  1. [Identification of meridian-acupoint diagrams and meridian diagrams]. (United States)

    Shen, Wei-hong


    In acu-moxibustion literature, there are two kinds of diagrams, meridian-acupoint diagrams and meridian diagrams. Because they are very similar in outline, and people now have seldom seen the typical ancient meridian diagrams, meridian-acupoint diagrams have been being incorrectly considered to be the meridian diagrams for a long time. It results in confusion in acu-moxibustion academia. The present paper stresses its importance in academic research and introduces some methods for identifying them correctly. The key points for identification of meridian-acupoint diagrams and meridian diagrams are: the legend of diagrams and the drawing style of the ancient charts. In addition, the author makes a detailed explanation about some acu-moxibustion charts which are easily confused. In order to distinguish meridian-acupoint diagrams and meridian diagrams correctly, he or she shoulnd understand the diagrams' intrinsic information as much as possible and make a comprehensive analysis about them.

  2. Study on stability of DMS meridian detector. (United States)

    Yang, Ning; Huang, Li; Yuan, Jiamin; Zhang, Zhifang; Yang, Zhimin


    The stability of meridian detector was the basis to study meridian through conductance method. Ancient documents mentioned that the human body's blood could change with the time and meridians. When qi and blood came, the qi and blood would be full of that place; when qi and blood gone, the local skin shining could fade and recess. It liked the tidal fluctuation, then caused the corresponding acupuncture points conductance value changes. Modern studies had reported that meridian detector instrument the skin area of twelve meridians acupuncture points could change along with time within 24 hours. In this circumstance, whether the conductance values changes in human acupuncture points had statistical significance was vital important. DMS meridian detector instruction was adopt to measure the twelve meridian jingyuan acupuncture point in order to analyze the acupuncture point conductance value changes within one day.

  4. Defining meridians: a modern basis of understanding. (United States)

    Longhurst, John C


    Acupuncture, one of the primary methods of treatment in traditional Oriental medicine, is based on a system of meridians. Along the meridians lie acupuncture points or acupoints, which are stimulated by needling, pressure or heat to resolve a clinical problem. A number of methods have been used to identify meridians and to explain them anatomically. Thus, tendinomuscular structures, primo-vessels (Bonghan ducts), regions of increased temperature and low skin resistance have been suggested to represent meridians or as methods to identify them. However, none of these methods have met the criteria for a meridian, an entity that, when stimulated by acupuncture can result in clinical improvement. More recently, modern physiologists have put forward the "neural hypothesis" stating that the clinical influence of acupuncture is transmitted primarily through stimulation of sensory nerves that provide signals to the brain, which processes this information and then causes clinical changes associated with treatment. Although additional research is warranted to investigate the role of some of the structures identified, it seems clear that the peripheral and central nervous system can now be considered to be the most rational basis for defining meridians. The meridian maps and associated acupoints located along them are best viewed as road maps that can guide practitioners towards applying acupuncture to achieve optimal clinical results.

  5. A new definition of an acupuncture meridian. (United States)

    Kovich, Fletcher


    This article provides a new definition of an acupuncture meridian. It suggests that a meridian consists of a distal tract of tissue that is affected by organ function. In the 1960's, Kim discovered the primo vascular system, and regarded the superficial primo vessels as equating to the meridians. Instead, this article suggests that the superficial primo vessels merely underlie the meridians, in that they enable their creation, which is why some meridians are said to occur along the paths of superficial primo vessels. But the meridians themselves do not have a dedicated anatomical structure; instead they are merely tracts of tissue whose normal function is impeded when the related abdominal organ is stressed. It is hypothesised that the organ information is communicated in electrical waves that may travel through the connective tissue sheaths of the superficial primo vessels. Hence the primo vessels serve as an inadvertent transport for this information, but the organ information is independent of the physiological purpose of the primo vascular system, as are the resultant meridians.

  6. Alice Walker’s Womanism in Meridian

    Institute of Scientific and Technical Information of China (English)

    GAN Lin


    Meridian is one of Alice Walker’s early work. It tells a story that happened in the American south during the 1960s and early 70s’. It describes the life of the main character, Meridian Hill, a black woman from a southern town, who got out of the oppression of white society, and ends up in participate in Civil Rights Movement. The paper firstly illustrates the soul of womanism—anti-sexism, anti-racism, sisiterhood as well as the maternity love, then analyzes how these theories permeated into the novel—Meridian. The paper paid attention to the function of this novel on the improvement of Alice Walker ’s womanism. In proving that womanism not only permeates into Meridian, but also improved womanism from many perspectives, it comes to the conclusion that Meridian is a novel to improve Alice Walker’s womanism, it serves as the good novel to highlight the African Culture, and made a great contribution for the encouragement of black women to seek for freedom in the society.

  7. Investigation of the Lower Resistance Meridian: Speculation on the Pathophysiological Functions of Acupuncture Meridians

    Directory of Open Access Journals (Sweden)

    Weisheng Yang


    Full Text Available It was pointed out in the two earlier papers of the present author that the meridians are in fact zones in the loose connective tissue containing richer interstitial fluid and thus are lower-resistance passages for diffusion of meridian-signal carriers or mediators. Moreover, a hypothesis, which incorporates the wide variety of functions of the loose connective tissue, the circulatory system, and the nervous system into the meridian function, has been proposed and in the hypothesis the mast cell plays some key roles. In the present paper, considering also the latest knowledge on cell migration along with some existing experimental results, it is further pointed out that meridians ought to be lower-resistance passages for chemotactic migration of cells and mast cells can indeed migrate longitudinally along meridians. Finally, the present paper points out that if we add the last two points to the hypothesis and keep in mind that mast cells have been known very recently to be versatile regulators of inflammation, tissue remodeling, host defense, and homeostasis, the rich pathophysiological functions of the meridian pointed out by the traditional Chinese medicine can be understood quite naturally.

    Tan, Cheng; Zhang, Chang; Zhang, Jiajia; Wang, Jun


    For the treatment of primary dysmenorrhea, professor ZHAO Jiping focuses on meridian diagnosis and inspection, and uses pressing methods to locate the response points along the meridian, including acupoints and aishi points. During the stage of attack, it is essential to press along the spleen meridian, mainly Sanyinjiao (SP 6), Diji (SP 8) and Yinlingquan (SP 9); during the stage of remission, it is essential to press along the bladder meridian and stomach meridian, mainly Ganshu (BL 18), Pishu (BL 20), Weishu (BL 21), Shenshu (BL 23) and Zusanli (ST 36). The differences between deficiency syndrome and excess syndrome lead to the different feelings of doctors and patients. Combined with the results of meridian diagnosis and inspection, the aim of treatment can be achieved by different acupuncture methods. Professor ZHAO pays attention to the treatment of accompanied symptoms and timing of treatment, since the relief of accompanied syndromes and selection of timing are keys to relieving patient's pain.

  10. Electrical impedance along connective tissue planes associated with acupuncture meridians

    Directory of Open Access Journals (Sweden)

    Hammerschlag Richard


    Full Text Available Abstract Background Acupuncture points and meridians are commonly believed to possess unique electrical properties. The experimental support for this claim is limited given the technical and methodological shortcomings of prior studies. Recent studies indicate a correspondence between acupuncture meridians and connective tissue planes. We hypothesized that segments of acupuncture meridians that are associated with loose connective tissue planes (between muscles or between muscle and bone visible by ultrasound have greater electrical conductance (less electrical impedance than non-meridian, parallel control segments. Methods We used a four-electrode method to measure the electrical impedance along segments of the Pericardium and Spleen meridians and corresponding parallel control segments in 23 human subjects. Meridian segments were determined by palpation and proportional measurements. Connective tissue planes underlying those segments were imaged with an ultrasound scanner. Along each meridian segment, four gold-plated needles were inserted along a straight line and used as electrodes. A parallel series of four control needles were placed 0.8 cm medial to the meridian needles. For each set of four needles, a 3.3 kHz alternating (AC constant amplitude current was introduced at three different amplitudes (20, 40, and 80 μAmps to the outer two needles, while the voltage was measured between the inner two needles. Tissue impedance between the two inner needles was calculated based on Ohm's law (ratio of voltage to current intensity. Results At the Pericardium location, mean tissue impedance was significantly lower at meridian segments (70.4 ± 5.7 Ω compared with control segments (75.0 ± 5.9 Ω (p = 0.0003. At the Spleen location, mean impedance for meridian (67.8 ± 6.8 Ω and control segments (68.5 ± 7.5 Ω were not significantly different (p = 0.70. Conclusion Tissue impedance was on average lower along the Pericardium meridian, but not

  11. The meridian system and mechanism of acupuncture—A comparative review. Part 1: The meridian system

    Directory of Open Access Journals (Sweden)

    Shyang Chang


    Full Text Available In traditional Chinese medicine (TCM, acupuncture has been used to heal various diseases and physiologic malfunctions in clinical practice for more than 2500 years. Due to its efficacy, acupuncture has been recommended by the World Health Organization in 1980 as an effective alternative therapy for 43 different disorders. Over the past few decades, various theories of the meridian system and mechanisms have been proposed to explain how acupuncture might work. Most of these mechanisms, however, cannot yet explain conclusively why acupuncture is efficacious in treating so many different diseases. A plausible mechanism has been unavailable until recently. This is the first of a three-part series that aims to provide a comparative review of the aforementioned topics. Part 1 reviews the current indications for acupuncture, basic concepts of TCM, and the essence of the meridian system. To establish a mathematically rigorous framework of TCM, the chaotic wave theory of fractal continuum is proposed. This theory is then applied to characterize the essence of the meridian system. Parts 2 and 3 will review the possible mechanisms of acupuncture analgesia and acupuncture therapies, respectively, based on biochemical, bioelectromagnetic, chaotic wave, and neurophysiologic approaches. It is sincerely hoped that this series of review articles can promote an understanding of the meridian system and acupuncture mechanisms to help patients in a logical and passionate way.

  12. The Meridians of Reference of Indian Astronomical Canons (United States)

    Mercier, R.

    The canons of Sanskrit astronomy depend on mean motions which are normally postulated to refer to the central meridian of Ujjain. The present work is a statistical analysis of these mean motions designed to discover the optimum position of the meridian, by comparison with modern mean motions. This follows earlier work done by Billard in determining the optimum year.

    Deng, Kaiwen; Tao, Yeqin; Tang, Wenhan; He, Fuyuan; Liu, Wenlong; Shi, Jilian; Yang, Yantao; Zhou, Yiqun; Chang, Xiaorong


    With human placed in the whole nature, by following the biologic evolution path, the property of channel structure for "imprinting template" in meridian and zang-fu was explored with supramolecular chemistry. In the history of biologic evolution, each molecule in "molecule society" gradually developed into various highly-ordered supramolecular bodies based on self-identification, self-assembly, self-organization, self-replicating of"imprinting template", and thereby the original biochemical system was established, and finally evolved into human. In the forming process of supramolecular bodies, the channel structure of"imprinting template" in guest supramolecular bodies would be kept by host supramolecular bodies, and communicate with the outside to exchange materials, energy, information, otherwise life phenomenon could not continue, for which it was the chemical nature of biolo-gical supramolecular bodies for body to develop meridian. Therefore, the human was a gigantic and complicated supramolecules body in biological nature, and possessed the supramolecules "imprinting template" at each stage of evolution, for which the meridians were formed. When meridians converged, acupoints appeared; when acupointsconverged, zang-fu appeared. With the promotion of the blood from heart, according to"imprinting template", the guest supramolecular bodies and host meridian produced qi -analysis, which was the qi -phenomenon of guest in meridian. It presented as zang-fu image of physiology and pathology as well as action regularities of medication and acupuncture tolerance, by which current various meridian viewpoints could be explained and propose the hypothesis of meridian supramolecular bodies. The meridian and its phenomenon was decide by its "imprinting template" of supramolecular bodies and self-reaction regularities, which abided through the living nature. This was the substance for meridian biology.

  14. Comparison of Acupuncture Effect on Blood Perfusion between Needling Nonacupoint on Meridian and Needling Nonacupoint off Meridian

    Directory of Open Access Journals (Sweden)

    Wei-Bo Zhang


    Full Text Available To verify the ancient theory of rather missing the acupoint than missing the meridian, acupuncture at nonacupoint on meridian and acupuncture at nonacupoint off meridian were performed, respectively. The blood perfusion (BP on the calf around bladder meridian area was measured with a laser Doppler perfusion imager before, during, and after acupuncture. The whole scanning field was divided into seven subareas, and mean BP on each area was calculated. The ratio of mean BP between a subarea and a reference subarea was gotten, and then the change rate was calculated as ratio change rate (RCR. The results showed that RCR on bladder meridian area and around Chengshan (BL57 during or after acupuncture at nonacupoint on meridian was significantly higher than that at nonacupoint off meridian, which supports the ancient theory. Such differences may be attributable to some factors that can facilitate the signals transmission and produce a better acupuncture effect, such as richer nerve terminals, blood vessels, and mast cells which can produce stronger signals on the acupoints and the low hydraulic resistance channel along meridians which plays a role of signal transmitting channel to get a better effect of acupuncture.

  15. Information Models of Acupuncture Analgesia and Meridian Channels

    Directory of Open Access Journals (Sweden)

    Chang Hua Zou


    Full Text Available Acupuncture and meridian channels have been major components of Chinese and Eastern Asian medicine—especially for analgesia—for over 2000 years. In recent decades, electroacupuncture (EA analgesia has been applied clinically and experimentally. However, there were controversial results between different treatment frequencies, or between the active and the placebo treatments; and the mechanisms of the treatments and the related meridian channels are still unknown. In this study, we propose a new term of infophysics therapy and develop information models of acupuncture (or EA analgesia and meridian channels, to understand the mechanisms and to explain the controversial results, based on Western theories of information, trigonometry and Fourier series, and physics, as well as published biomedical data. We are trying to build a bridge between Chinese medicine and Western medicine by investigating the Eastern acupuncture analgesia and meridian channels with Western sciences; we model the meridians as a physiological system that is mostly constructed with interstices in or between other physiological systems; we consider frequencies, amplitudes and wave numbers of electric field intensity (EFI as information data. Our modeling results demonstrate that information regulated with acupuncture (or EA is different from pain information, we provide answers to explain the controversial published results, and suggest that mechanisms of acupuncture (or EA analgesia could be mostly involved in information regulation of frequencies and amplitudes of EFI as well as neuronal transmitters such as endorphins.

  16. [Characteristics of infrared radiation of meridians and acupoints]. (United States)

    Zheng, Juan-Juan; Shen, Xue-Yong; Zhao, Yi


    Infrared radiation temperature and characteristics of infrared spectrum of meridians and acupoints are summarized in this article. The infrared radiant track along the running course of meridians might be a ubiquitous phenomenon of the vital activity. The high temperature bands below the meridian lines at the cuticular layer are often taken as the manifestation of the tract. It could be induced by various stimulations on acupoints with warm-needling as the best causative method. High temperature and low resistance are considered as 2 features of the acupoint zone. The adenosine-triphosphate energy metabolism of the acupoint zone is higher than the non-point zone, which indicates that essential physiological and pathological information are carried by infrared radiation temperature of acupoint and infrared spectrum of acupoint. However, it is realized that study on characteristics of infrared radiation only is far from enough to reveal the essence of meridians and acupoints. And much still remains to be done in strengthening basic studies of characteristics of infrared radiation, structure pattern of meridians and acupoints as well as volt-ampere characteristics.

  17. Global communication using a constellation of low earth meridian orbits (United States)

    Oli, P. V. S.; Nagarajan, N.; Rayan, H. R.


    The concept of 'meridian orbits' is briefly reviewed. It is shown that, if a satellite in the meridian orbit makes an odd number of revolutions per day, then the satellite passes over the same set of meridians twice a day. Satellites in such orbits pass over the same portion of the sky twice a day and every day. This enables a user to adopt a programmed mode of tracking, thereby avoiding a computational facility for orbit prediction, look angle generation, and auto tracking. A constellation of 38 or more satellites placed in a 1200 km altitude circular orbit is favorable for global communications due to various factors. It is shown that appropriate phasing in right ascension of the ascending node and mean anomaly results in a constellation, wherein each satellite appears over the user's horizon one satellite after another. Visibility and coverage plots are provided to verify the continuous coverage.

  18. On dermatomes, meridians and points: results of a quasiexperimental study. (United States)

    Sánchez-Araujo, Max; Luckert-Barela, Ana J; Sánchez, Nathalia; Torres, Juan; Conde, Jesus Eloy


    Traditional Chinese medicine (TCM) meridians and points run vertically, reflecting their function in the Zhang-Fu system (meridian pattern). However, the trunk's spinal nerves show a traverse orientation, or a 'horizontal pattern'. The aim of the present work was to evaluate, via a cognitive quasiexperiment, whether the clinical indications of the points on the trunk are associated with their meridian function or with their innervation and visceral-somatic connection. The points in each dermatome of the trunk were considered crosswise, regardless of their meridians. The clinical indications for each point were differentiated into two mutually exclusive categories: (a) vertical distribution effect (VDE) or 'meridian pattern', when indications were quite different regarding the indications for the other points on the dermatome; and (b) transverse distribution effects (TDE) or 'horizontal pattern', represented by mainly local or segmental indications except for Shu-Mu points. After observing that the proportions between both categories often exceeded 60% in pilot samples, 60% was adopted as the reference value. A total of 22 dermatomes accommodated 148 points with 809 indications, of which 189 indications (23.4%) exhibited VDE features, whereas 620 (76.6%) exhibited TDE features. A TDE/VDE ratio of 3 : 1 implies that the clinical indications for the points of any dermatome on the torso are similar, regardless of their meridians, and suggests that most of the indications for trunk points involve a 'horizontal pattern' due to their neurobiological nature. These findings may help in understanding acupuncture's neurobiology and clarify some confusing results of clinical research, for example, excluding sham acupuncture as an inert intervention for future clinical trials.

    Ren, Jian-Ning


    To explore the mechanism of insomnia caused by "stomach disorder could lead to excess of yang-qiao meridian" and clinical application of treating insomnia with acupoints in qiao meridian as the main points. From meridian theory, intersection between stomach meridian of Foot-Yangming and yang-qiao meridian is through Chengqi (ST 1). Qiao meridian for sleep is mainly because it is connected with eyes through the Bladder Meridian of Foot-Taiyang. For Stomach Meridian of Foot-Yangming is intersected with the Bladder Meridian of Foot-Taiyang in Jingming (BL 1), and intersected with yin and yang qiao meridian beside the mouth and under the eye, once functional disorder of the stomach, it can affect qi movements of the whole body and give rise to various pathological changes that cause insomnia. Meanwhile examples are given to explain the clinical application of treating subborn insomnia with corresponding acupoint of stomach and yang-qiao meridian.

    Yang, Zongbao; Wang, Yadong; Liu, Qiong; Liu, Mi; Chen, Huijuan; Chang, Xiaorong


    To observe the effects of electroacupuncture (EA) at stomach meridian acupoints on expression of oxidation damage factors in serum and gastric mucosal cells in rats with gastric ulcer, and to explore the mechanism of EA at stomach meridian acupoints for oxidative damage in rats with gastric ulcer. Forty clean-grade SD rats were randomly divided into a normal group, a model group, a stomach meridian group and a gallbladder meridian group, ten rats in each one. Except the normal group, rats in the remaining groups were applied the restraint-cold stress method to establish the model of gastric ulcer. Rats in the normal group and model group received no treatment; rats in the stomach meridian group were treated with EA at "Liangmen" (ST 21) and "Zusanli" (ST 36); rats in the gallbladder meridian group were treated with EA at "Riyue" (GB 24) and "Yanglingquan" (GB 34). The EA was given for 30 min, once a day for 7 days totally. The change of gastric mucosal morphology was observed by routine light microscope; enzyme linked immunosorbent assay was used to detect the expressions of malondialdehyde (MDA), glutathione peroxidase (GSH-px) and tumor necrosis factor-α (TNF-α), interleukin-2(IL-2), interleukin-6(IL-6) in serum and gastric mucosal cells of rats. After treatment, compared with the model group, the gastric mucosal damage index was decreased in the stomach meridian group and gallbladder meridian group (both P stomach meridian group (all P stomach meridian group rats ( P stomach meridian acupoints is likely to inhibit the expressions of oxidative damage factors to promote the repair of gastric mucosal injury, which indicates the correlation between meridians and zang-fu .

  5. Acupuncture meridians demythified. A study using the radioactive tracer method

    International Nuclear Information System (INIS)

    Simon, J.; Esquerre, J.P.; Guiraud, R.; Guiraud, G.; Lazorthes, Y.


    Radioactive trajectories can be visualized by injecting a radioactive tracer, technetium 99 m, at the site of acupuncture points. To determine the exact nature of these trajectories we performed several experiments on healthy volunteers, and our results may be summarized as follows. The target organs of technetium 99 m, and notably the thyroid gland, were always visualized. The circulating radioactivity, visible on scintiscans and confirmed by venous blood counts, was not negligible. The radioactive trajectories we observed were often divided at their starting point and did not extend along the whole length of the acupuncture meridians they might have made visible. The radioactive trajectories disappeared after venous blockade to reappear when the blockade was lifted. Finally, the radioactive trajectories obtained were very similar after injection at the acupuncture point and at a control point. These findings indicate a lymphatic and venous drainage of the radioactive tracer at the site of injection followed by transportation through the veins, rather than visualization of acupuncture meridians as suggested by some authors [fr

  9. An information entropy model on clinical assessment of patients based on the holographic field of meridian (United States)

    Wu, Jingjing; Wu, Xinming; Li, Pengfei; Li, Nan; Mao, Xiaomei; Chai, Lihe


    Meridian system is not only the basis of traditional Chinese medicine (TCM) method (e.g. acupuncture, massage), but also the core of TCM's basic theory. This paper has introduced a new informational perspective to understand the reality and the holographic field of meridian. Based on maximum information entropy principle (MIEP), a dynamic equation for the holographic field has been deduced, which reflects the evolutionary characteristics of meridian. By using self-organizing artificial neural network as algorithm, the evolutionary dynamic equation of the holographic field can be resolved to assess properties of meridians and clinically diagnose the health characteristics of patients. Finally, through some cases from clinical patients (e.g. a 30-year-old male patient, an apoplectic patient, an epilepsy patient), we use this model to assess the evolutionary properties of meridians. It is proved that this model not only has significant implications in revealing the essence of meridian in TCM, but also may play a guiding role in clinical assessment of patients based on the holographic field of meridians.

  10. [Human body meridian spatial decision support system for clinical treatment and teaching of acupuncture and moxibustion]. (United States)

    Wu, Dehua


    The spatial position and distribution of human body meridian are expressed limitedly in the decision support system (DSS) of acupuncture and moxibustion at present, which leads to the failure to give the effective quantitative analysis on the spatial range and the difficulty for the decision-maker to provide a realistic spatial decision environment. Focusing on the limit spatial expression in DSS of acupuncture and moxibustion, it was proposed that on the basis of the geographic information system, in association of DSS technology, the design idea was developed on the human body meridian spatial DSS. With the 4-layer service-oriented architecture adopted, the data center integrated development platform was taken as the system development environment. The hierarchical organization was done for the spatial data of human body meridian via the directory tree. The structured query language (SQL) server was used to achieve the unified management of spatial data and attribute data. The technologies of architecture, configuration and plug-in development model were integrated to achieve the data inquiry, buffer analysis and program evaluation of the human body meridian spatial DSS. The research results show that the human body meridian spatial DSS could reflect realistically the spatial characteristics of the spatial position and distribution of human body meridian and met the constantly changeable demand of users. It has the powerful spatial analysis function and assists with the scientific decision in clinical treatment and teaching of acupuncture and moxibustion. It is the new attempt to the informatization research of human body meridian.

  11. Effective acupuncture practice through diagnosis based on distribution of meridian pathways & related syndromes. (United States)

    Chen, Yemeng; Zheng, Xin; Li, Hui; Zhang, Qunce; Wang, Tianfang


    This article discusses the importance of acupuncture practice utilizing diagnosis and distribution of various meridians and connecting channels based on meridian theory. The meridian system is considered as basic anatomy for acupuncture, so the corresponding pathways and related syndromes of different channels should play a key role in differentiation, known as meridian-related pattern differentiation. Since this doctrine originated in ancient times and was not so well developed in later generations, many acupuncturists are not able to utilize it efficiently. The authors survey how this doctrine was weakened during the past century, especially in acupuncture education for foreigners, and how this important method is currently being reinvigorated. This article also lays out the ways this doctrine can be applied clinically and introduces examples of a variety of indications including some difficult cases, such as whiplash injury, intervertebral disc herniation, oculomotor nerve paralysis, and eczema, etc.

  12. Systems Biology of Meridians, Acupoints, and Chinese Herbs in Disease

    Directory of Open Access Journals (Sweden)

    Li-Ling Lin


    Full Text Available Meridians, acupoints, and Chinese herbs are important components of traditional Chinese medicine (TCM. They have been used for disease treatment and prevention and as alternative and complementary therapies. Systems biology integrates omics data, such as transcriptional, proteomic, and metabolomics data, in order to obtain a more global and complete picture of biological activity. To further understand the existence and functions of the three components above, we reviewed relevant research in the systems biology literature and found many recent studies that indicate the value of acupuncture and Chinese herbs. Acupuncture is useful in pain moderation and relieves various symptoms arising from acute spinal cord injury and acute ischemic stroke. Moreover, Chinese herbal extracts have been linked to wound repair, the alleviation of postmenopausal osteoporosis severity, and anti-tumor effects, among others. Different acupoints, variations in treatment duration, and herbal extracts can be used to alleviate various symptoms and conditions and to regulate biological pathways by altering gene and protein expression. Our paper demonstrates how systems biology has helped to establish a platform for investigating the efficacy of TCM in treating different diseases and improving treatment strategies.

    Baeckkyoung Sung


    Full Text Available Objective : In this article, we report on the intradermal Alcian blue staining method for tracing the meridians of acupuncture. Methods : 1% Alcian blue solution was injected into acupoints by using a 0.5mL insulin syringe with a 31-gauge needle, then the skin was incised and was observed under a stereoscopic microscope. The specimens were examined by using immunohistochemical methods and were observed under a confocal laser scanning microscope. Results : A threadlike structure, which was visualized with Alcian blue, existed in dermis layer and proceeded to hypodermis. In this structure, characteristic alignments of rod- shaped nuclei and 1-2μm sized DNA granules were observed. Furthermore, abundant blood capillary plexuses, peripheral nerve endings, and a corpusclelike structure(about 300μm in diameter were visualized in the skin tissues of acupoints. Conclusion : It was concluded that the specific threadlike and corpuscle-like structures corresponded to superficial Bonghan duct and corpuscle, respectively.

  14. Bioceramic Resonance Effect on Meridian Channels: A Pilot Study

    Directory of Open Access Journals (Sweden)

    Ting-Kai Leung


    Full Text Available Bioceramic is a kind of material which emits nonionizing radiation and luminescence, induced by visible light. Bioceramic also facilitates the breakup of large clusters of water molecules by weakening hydrogen bonds. Hydrogen bond weakening, which allows water molecules to act in diverse ways under different conditions, is one of the key mechanisms underlying the effects of Bioceramic on biophysical and physical-chemical processes. Herein, we used sound to amplify the effect of Bioceramic and further developed an experimental device for use in humans. Thirteen patients who suffered from various chronic and acute illnesses that severely affected their sleep patterns and life quality were enrolled in a trial of Bioceramic resonance (i.e., rhythmic 100-dB sound waves with frequency set at 10 Hz applied to the skin surface of the anterior chest. According to preliminary data, a “Propagated Sensation along Meridians” (PSM was experienced in all Bioceramic resonance-treated patients but not in any of the nine control patients. The device was believed to enhance microcirculation through a series of biomolecular and physiological processes and to subject the specific meridian channels of Traditional Chinese Medicine (TCM to coherent vibration. This noninvasive technique may offer an alternative to needle acupuncture and other traditional medical practices with clinical benefits.

  15. [Study on meridian tropism of medicinal property theory for Chines medicines by supramolecular chemistry (I)]. (United States)

    He, Fu-yuan; Deng, Kai-wen; Yang, Yan-tao; Zhou, Yi-qun; Shi, Ji-lian; Liu, Wen-long; Tang, Yu


    In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.

    To explore the relation between gap junction and meridian phenomenon. The oxygen partial pressure in acupoints [see text for formula] and in their corresponding non-acupoints of the Bladder Meridian was observed with the needle-type tissue oxygen tension sensor in the gap junction blocking goats by 1-Heptanol injection and the Connexin 43 (Cx43) gene knockout mice. (1) The oxygen partial pressure in acupoints of Bladder Meridian on goats was higher than that in non-acupoints after 1-Heptanol injection with significant differences between them (both P oxygen partial pressure in acupoints of Bladder Meridian on goats increased significantly after injecting 1-Heptanol as compare with that either injecting normal saline or injecting nothing with significant differences between them (all P oxygen partial pressure in acupoints of the Bladder Meridian was significantly higher than that in the non-acupoint controls in Cx43 wild type (WT) mice (all P oxygen partial pressure between acupoints and non-acupoint controls showed no significant differences (all P > 0.05). (4) In acupoints, the oxygen partial pressure in Cx43 WT mice was significantly higher than that in Cx43 HT mice (all P 0.05). Gap junction maybe the essential factor in signal transduction of acupuncture.

  18. The existence of propagated sensation along the meridian proved by neuroelectrophysiology (United States)

    Xu, Jinsen; Zheng, Shuxia; Pan, Xiaohua; Zhu, Xiaoxiang; Hu, Xianglong


    Propagated sensation along the meridian can occur when acupoints are stimulated by acupuncture or electrical impulses. In this study, participants with notable propagated sensation along the dian were given electro-acupuncture at the Jianyu (LI15) acupoint of the large intestine meridian. When participants stated that the sensation reached the back of their hand, regular nervous system action discharge was examined using a physiological recording electrode placed on the superficial branch of the radial nerve. The topographical maps of brain-evoked potential in the primary cortical somatosensory area were also detected. When Guangming (GB37) acupoint in the lower limb and Hegu (LI4) acupoint in the upper limb were stimulated, subjects without propagated sensation along the meridian exhibited a high potential reaction in the corresponding area of the brain cortical so-matosensory area. For subjects with a notable propagated sensation along the meridian, the tion area was larger and extended into the face representative area. These electrophysiological measures directly prove the existence of propagated sensation along the meridian, and the pheral stimulated site is consistent with the corresponding primary cortical somatosensory area, which presents a high potential reaction.

    Ming-Yen Tsai

    Full Text Available OBJECTIVES: The Meridian Energy Analysis Device is currently a popular tool in the scientific research of meridian electrophysiology. In this field, it is generally believed that measuring the electrical conductivity of meridians provides information about the balance of bioenergy or Qi-blood in the body. METHODS AND RESULTS: PubMed database based on some original articles from 1956 to 2014 and the authoŕs clinical experience. In this short communication, we provide clinical examples of Meridian Energy Analysis Device application, especially in the field of traditional Chinese medicine, discuss the reliability of the measurements, and put the values obtained into context by considering items of considerable variability and by estimating sample size. CONCLUSION: The Meridian Energy Analysis Device is making a valuable contribution to the diagnosis of Qi-blood dysfunction. It can be assessed from short-term and long-term meridian bioenergy recordings. It is one of the few methods that allow outpatient traditional Chinese medicine diagnosis, monitoring the progress, therapeutic effect and evaluation of patient prognosis. The holistic approaches underlying the practice of traditional Chinese medicine and new trends in modern medicine toward the use of objective instruments require in-depth knowledge of the mechanisms of meridian energy, and the Meridian Energy Analysis Device can feasibly be used for understanding and interpreting traditional Chinese medicine theory, especially in view of its expansion in Western countries.

  4. Is There Volume Transmission Along Extracellular Fluid Pathways Corresponding to the Acupuncture Meridians?

    Directory of Open Access Journals (Sweden)

    Weibo Zhang


    Full Text Available Volume transmission is a new major communication signaling via extracellular fluid (interstitial fluid pathways. It was proposed by the current authors that such pathways can explain the meridian phenomena and acupuncture effects. To investigate whether meridian-like structures exist in fish body and operate via volume transmission in extracellular fluid pathways, we injected alcian blue (AB under anesthesia into Gephyrocharax melanocheir, which has a translucent body. The migration of AB could be seen directly and was recorded by a digital camera. The fish was then embedded and cut transversely to observe the position of tracks in three dimensions. Eight longitudinal threadlike blue tracks were recognized on the fish. The positions of these threadlike tracks were similar to meridians on the human body. Transverse sections showed that these tracks distributed to different layers of distinct subcutaneous loose connective tissues and intermuscular septa. Lymphatic vessels were sometimes associated with the extracellular blue tracks where the migration of AB occurred. Extracellular fluid pathways were found on fish through their transport of AB. These pathways operating via volume transmission appeared to be similar in positions and functions to the acupuncture meridians in Chinese medicine.

  6. Principle Study of Head Meridian Acupoint Massage to Stress Release via Grey Data Model Analysis. (United States)

    Lee, Ya-Ting


    This paper presents the scientific study of the effectiveness and action principle of head meridian acupoint massage by applying the grey data model analysis approach. First, the head massage procedure for massaging the important head meridian acupuncture points including Taiyang, Fengfu, Tianzhu, Fengqi, and Jianjing is formulated in a standard manner. Second, the status of the autonomic nervous system of each subject is evaluated by using the heart rate variability analyzer before and after the head massage following four weeks. Afterward, the physiological factors of autonomic nerves are quantitatively analyzed by using the grey data modeling theory. The grey data analysis can point out that the status of autonomic nervous system is greatly improved after the massage. The order change of the grey relationship weighting of physiological factors shows the action principle of the sympathetic and parasympathetic nerves when performing head massage. In other words, the grey data model is able to distinguish the detailed interaction of the autonomic nervous system and the head meridian acupoint massage. Thus, the stress relaxing effect of massaging head meridian acupoints is proved, which is lacked in literature. The results can be a reference principle for massage health care in practice.

    To construct the study platform for meridians and acupoints by analyzing the status and current problems of teaching Meridians and Acupoints and in accordance with the principles as "knowledge fragmentation, game breakthrough and overall assessment" and observe the application effect in the flipped classroom. Totally two hundred and five 2014 grade bachelor candidates from four classes of the department of acupuncture-moxibustion and tuina were selected from Hunan Junior College of TCM. They were randomized into an observation group (102 cases) and a control group (103 cases). in the observation group, the flipped classroom was performed by adopting the study platform of meridians and acupoints. Additionally, the team cooperation learning and overall assessment were conducted. In the control group, the traditional teaching system was adopted, in which, the mode of "teacher's demonstration-to-discussion in group-to-teachers' assessment" and the operation check at the end of the semester were applied. The learning effect and the self-learning ability were evaluated at the end of semester in the two groups. The satisfaction survey was conducted in the observation group. In the observation group, the drawing of meridian running course and locating the acupoints, as well as the self-learning ability were better than those in the control group, indicating the significant differences (all P flipped classroom and the satisfaction of participation were slightly low. The study platform of learning Meridians and Acupoints was applied in the flipped classroom and has effectively improved the practical manipulation results and self-learning ability. However, the interestingness and interactivity of the platform are expected to be improved. The effective teaching design should be adopted in the flipped classroom to improve the students' desire of participation.

  8. [Analysis of clinical characteristics of traditional Chinese and Western medicine in Professor Jiang Liangduo's theory of "sanjiao meridian stasis"]. (United States)

    Wang, Hai-Yan; Jiang, Liang-Duo; Ma, Qing; Xu, Dong; Tang, Shi-Huan; Luo, Zeng-Gang


    In the clinical practice, Professor Jiang Liangduo, a national senior Chinese medicine doctor, has created the theory of "sanjiao meridian stasis" from the theory of meridian dialectics and from the overall state. In this paper, the traditional Chinese medicine and Western medicine clinical characteristics of sanjiao meridian stasis theory which is often used by Professor Jiang Liangduo in the treatment of out-patient syndrome differentiation, were first studied and summarized to investigate its inherent regularity. First, the source of data and research methods were introduced, and then the Traditional Chinese Medicine Inheritance Support System was used with the method of data mining to retrospectively analyze the disease characteristics of Chinese and Western medicine in 279 patients with sanjiao meridian stasis diagnosed by Professor Jiang in 2014. Then the following main conclusions were made after research: sanjiao meridian stasis was more common in women as well as young and middle-aged population. Often manifested by prolonged treatment course, red tongue with yellowishfur, with good correlation between modern Western medicine diagnosis and TCM differentiation syndrome. The symptoms of sanjiao meridian stasis syndrome are mostly of heat syndromes, and middle-aged patients are the most common patients with stasis and stasis of sanjiao. Related information of Western medicine diagnosis can help to diagnose the "sanjiao meridian stasis". Copyright© by the Chinese Pharmaceutical Association.

  9. Statistical analysis of 4 types of neck whiplash injuries based on classical meridian theory. (United States)

    Chen, Yemeng; Zhao, Yan; Xue, Xiaolin; Li, Hui; Wu, Xiuyan; Zhang, Qunce; Zheng, Xin; Wang, Tianfang


    As one component of the Chinese medicine meridian system, the meridian sinew (Jingjin, (see text), tendino-musculo) is specially described as being for acupuncture treatment of the musculoskeletal system because of its dynamic attributes and tender point correlations. In recent decades, the therapeutic importance of the sinew meridian has become revalued in clinical application. Based on this theory, the authors have established therapeutic strategies of acupuncture treatment in Whiplash-Associated Disorders (WAD) by categorizing four types of neck symptom presentations. The advantage of this new system is to make it much easier for the clinician to find effective acupuncture points. This study attempts to prove the significance of the proposed therapeutic strategies by analyzing data collected from a clinical survey of various WAD using non-supervised statistical methods, such as correlation analysis, factor analysis, and cluster analysis. The clinical survey data have successfully verified discrete characteristics of four neck syndromes, based upon the range of motion (ROM) and tender point location findings. A summary of the relationships among the symptoms of the four neck syndromes has shown the correlation coefficient as having a statistical significance (P < 0.01 or P < 0.05), especially with regard to ROM. Furthermore, factor and cluster analyses resulted in a total of 11 categories of general symptoms, which implies syndrome factors are more related to the Liver, as originally described in classical theory. The hypothesis of meridian sinew syndromes in WAD is clearly supported by the statistical analysis of the clinical trials. This new discovery should be beneficial in improving therapeutic outcomes.

  10. An Examination of Personality Traits Associated with Autonomous Sensory Meridian Response (ASMR)


    Fredborg, Beverley; Clark, Jim; Smith, Stephen D.


    Autonomous Sensory Meridian Response (ASMR) is a perceptual condition in which the presentation of particular audio-visual stimuli triggers intense, pleasurable tingling sensations in the head and neck regions, which may spread to the periphery of the body. These triggering stimuli are often socially intimate in nature, and usually involve repetition of movements and/or sounds (e.g., hearing whispering, watching someone brush her hair). Reports of ASMR experiences first appeared in online com...

    The structure of the periodic solutions of the Stoermer problem, representing the magnetic field of the Earth, is examined by considering the equatorial oscillations of the charged particle and their 'vertical' bifurcations with meridian periodic oscillations. An infinity of new families of simple-periodic oscillations are found to exist in the vicinity of the 'thalweg' and four such new families are actually established by numerical integration. (Auth.)

  15. Patterns of Energy Imbalance of the Meridians in Patients with Temporomandibular Dysfunction. (United States)

    Rasera Zotelli, Vera L; Grillo, Cássia M; Bressiani Gil, Maria L; Wada, Ronaldo S; Sato, Jorge E; de Sousa, Maria da Luz R


    Temporomandibular dysfunction (TMD) is a set of changes that affects the muscles of mastication, temporomandibular joint, teeth, and associated periodontal and orofacial structures. According to Traditional Chinese Medicine, the imbalance of energy (Qi) circulating in the acupuncture meridians is always the primary etiologic cause of any physical manifestation. The aim of this study was to describe the patterns of Qi imbalance in patients with TMD by means of an objective measurement. The clinical study was conducted at the Piracicaba Dental School (FOP/Unicamp), in Piracicaba-SP, Brazil. We evaluated 40 adult volunteers with TMD. The Qi measurement was carried out by the researcher using the Ryodoraku method using 24 points representing the 12 acupuncture meridians: LU9 (Taiyuan), PC7 (Daling), HT7 (Shemen), SI5 (Yanggu), TE4 (Yangchi), LI5 (Yangxi), SP3 (Taibai), LR3 (Taichong), KI3 (Taixi), BL64 (Jinggu), GB40 (Qiuxu), and ST42 (Chongyang). The average total Qi of 40 volunteers (21.7 μA ± 1.5), was below the normal range (40-60 μA) and was classified as deficiency of Qi (empty). The coupled meridians that showed the highest Qi imbalance were the kidney (29.4 μA ± 2.8) and bladder (13.8 μA ± 1). The Qi planes with greatest imbalance were the Shao Yang and Shao Yin. In conclusion, volunteers with TMD presented a pattern of Qi deficiency, and the most prevalent imbalance patterns identified were in the kidney and bladder coupled meridians and in the energetic planes Shao Yin (heart/kidney) and Shao Yang (triple energizer/gall bladder).

The experimental group demonstrated a significantly larger decrease compared with the control group in measures of body composition, edema, total subjective stress, psychological stress, and subjective fatigue. Meridian acupressure massage can hasten the return to original body composition after childbirth.

  19. Possible role of epidermal keratinocytes in the construction of acupuncture meridians. (United States)

    Denda, Mitsuhiro; Tsutsumi, Moe


    Acupuncture meridians consist of a network of acupuncture points on the skin, stimulation of which is well established to have a variety of physiological effects. We have previously demonstrated that epidermal keratinocytes contain multiple sensory systems for temperature, mechanical stimuli, electric potentials and other stimuli. These sensory systems generate changes in the calcium-ion concentration in the epidermis, so epidermal keratinocytes can generate spatially-localized electro-physiological patterns in the skin. We have previously demonstrated signaling between epidermal keratinocytes and peripheral nerve systems. Therefore, stimuli sensed by epidermal keratinocytes might be transferred to the unmyelinated nerve fibers that are known to exist in the epidermis and, thence, to the spinal cord and brain. We propose that epidermal keratinocytes form an information-gathering network in the skin and that this network plays a key role in whole-body homeostasis in response to the changing environment. We also hypothesize that this network corresponds to the acupuncture meridians. As supporting examples, we present some striking calcium propagation patterns observed in cultured human keratinocytes after adenosine-triphosphate (ATP) stimulation. These results support the ideas that keratinocytes can generate spatially-restricted signaling patterns after environmental stimulation and that the cultures might be in-vitro models of meridians as an information-gathering network in skin.

    Miljenko Solarić


    Full Text Available The introduction provides a brief overview of using trigonometric chains for determining meridian arc lengths in Europe, as well as their extension to trigonometric networks in order to produce contemporary accurate maps in France. After Ruđer Bošković had visited Croatian-Hungarian Queen and Roman-German Empress Maria Theresa, she ordered Jesuit Joseph Liesganig to survey the meridian from Brno (Soběšice, over Vienna and Graz to Varaždin by establishing and surveying a trigonometric chain. That distance amounts to 320 km, i.e. the difference between latitude of the starting and finishing points of the chain equaled 2° 56' 45.85''. Two baselines were measured directly between Wiener Neustadt and Neunkirchen of 6410.903 Vienna fathom (12 158.175 m and between Seyring and Glizendorf in the Moravian field (Moravské pole, Marchfeld of 6387.862 Vienna fathom (12 114.478 m. Liesganig published previous Vienna Meridian survey results in Philosophical Transactions in London in 1768 and the final results in Latin in Dimensio Graduum Meridiani Viennensis et Hungarici in 1770. His results were quickly criticized and subsequently subjected to validation. Trigonometric point Varaždin is the first and oldest trigonometric point in Croatia.

  1. Full Meridian of Glory Perilous Adventures in the Competition to Measure the Earth

    CERN Document Server

    Murdin, Paul


    The Paris Meridian is the name of the line running north-south through the astronomical observatory in Paris. One of the original intentions behind the founding of the Paris Observatory was to determine and measure this line. To that end, the French government financed the Paris Academy of Sciences to do so in the seventeenth to nineteenth centuries employing both astronomers – people who study and measure the stars – and geodesists – people who study and measure the Earth. This book is about what they did and why. Full Meridian of Glory is the first English language presentation of this historical material in its entirety. It is an attractively written story of the scientists who created the Paris Meridian.

    Fan, Shi-Qi; Li, Sen; Liu, Jin-Ling; Yang, Jiao; Hu, Chao; Zhu, Jun-Ping; Xiao, Xiao-Qin; Liu, Wen-Long; He, Fu-Yuan


    The molecular connectivity index was adopted to explore the characteristics of supramolecular imprinting template of herbs distributed to liver meridian, in order to provide scientific basis for traditional Chinese medicines(TCMs) distributed to liver meridian. In this paper, with "12th five-year plan" national planning textbooks Science of Traditional Chinese Medicine and Chemistry of Traditional Chinese Medicine as the blueprint, literatures and TCMSP sub-databases in TCM pharmacology of northwest science and technology university of agriculture and forestry were retrieved to collect and summarize active constituents of TCM distributed to liver meridian, and calculate the molecular connectivity index. The average molecular connectivity index of ingredients distributed to liver meridian was 9.47, which was close to flavonoid glycosides' (9.17±2.11) and terpenes (9.30±3.62). Therefore, it is inferred that template molecule of liver meridian is similar to physicochemical property of flavonoid glycosides and terpenes, which could be best matched with imprinting template of liver meridian.

    Pan, Ru-Yu; Hsu, Yung-Chi; Wong, Chih-Shung; Lin, Shinn-Long; Li, Tsung-Ying; Cherng, Chen-Hwan; Ko, Shan-Chi; Yeh, Chun-Chang


    The aim of this study was to compare the short-term outcomes between 2 different treatments for unilateral chronic shoulder pain of myofascial origin, that is, local tender area related meridians (LTARMs) treatment and collateral meridian therapy (CMT), which were performed 6 times over a period of 4 weeks.Seventy patients with unilateral shoulder pain of chronic myofascial origin were enrolled. The patients were randomly assigned to 2 different treatment groups: 1 group received CMT (n = 35) and the other received LTARM (n = 35). Before and after the 2 treatment processes, all patients rated their overall pain intensity on a visual analogue scale (VAS) and a validated 13-question shoulder pain and disability index (SPADI) questionnaire was used to measure shoulder pain and functional impairment after therapy for 4 weeks.After CMT, the pain intensity was reduced after CMT. VAS score is reduced from 5.90 ± 2.07 (a mean of 5.90 and standard deviation of 2.07) to 3.39 ± 1.2. This was verified by the SPADI pain subscale scores (from 0.58 ± 0.193 to 0.33 ± 0.14). The pain-relief effect of CMT was significantly better than that of LTARM (VAS score from 5.78 ± 1.64 to 4.58 ± 1.40; P pain subscale score from 0.58 ± 0.16 to 0.45 ± 0.14, P pain, whereas the VAS scores for moderate pain were even higher in the LTARM group in 75% of patients (P chronic shoulder pain of myofascial origin than the LTARM treatment, where treatment with the former resulted in better functional recovery after 4 weeks than the latter.

  5. [Comparison of the compilation features of Science of Meridians and Acupoints among different editions]. (United States)

    Chen, Xiaojun

    The compilation features of Jingluo Shuxue Xue ( Science of Meridians and Acupoints ) among different editions were summarized and analyzed. Jingluo Xue ( Science of Meridians ) and Shuxue Xue ( Science of Acupoints ) published by Shanghai Scientific and Technical Publishers in 1984 are the pioneer as the textbook for the education of acupuncture discipline for the bachelor degree, but there is the big controversy for the editions in 1996. These two books were combined as one, titled Science of Meridians and Acupoints , 2013 edition, published by China Press of Traditional Chinese Medicine. It is concise and coherent in content and is regarded as the milestone in the history of textbook compilation. This book was re-edited in 2007 without major changes in content. The one in 2009 was revised a lot on the basis of the original several editions, published by Shanghai Scientific and Technical Publishers. But unfortunately, it did not bring the big impacts in China. The edition in 2012, published by China Press of Traditional Chinese Medicine had made the innovations besides integrating the achievements of the previous editions, characterized as preciseness and conciseness. By contrast, the edition in 2012, published by People's Medical Publishing House was accomplished by simple modification on the basis of the editions in 2003 and in 2007, without great innovation. Regarding the on-going publication of the textbooks in "the 13th five-year plan", it is viewed that the new edition of textbook should maintain the general framework of "the 12th five-year plan", based on which, a few questions should be revised appropriately. Additionally, "less words, more illustration" should be the basic principle for the revision of the new edition.

  6. Tolerance and nature of residual refraction in symmetric power space as principal lens powers and meridians change. (United States)

    Abelman, Herven; Abelman, Shirley


    Unacceptable principal powers in well-centred lenses may require a toric over-refraction which differs in nature from the one where correct powers have misplaced meridians. This paper calculates residual (over) refractions and their natures. The magnitude of the power of the over-refraction serves as a general, reliable, real scalar criterion for acceptance or tolerance of lenses whose surface relative curvatures change or whose meridians are rotated and cause powers to differ. Principal powers and meridians of lenses are analogous to eigenvalues and eigenvectors of symmetric matrices, which facilitates the calculation of powers and their residuals. Geometric paths in symmetric power space link intended refractive correction and these carefully chosen, undue refractive corrections. Principal meridians alone vary along an arc of a circle centred at the origin and corresponding powers vary autonomously along select diameters of that circle in symmetric power space. Depending on the path of the power change, residual lenses different from their prescription in principal powers and meridians are pure cross-cylindrical or spherocylindrical in nature. The location of residual power in symmetric dioptric power space and its optical cross-representation characterize the lens that must be added to the compensation to attain the power in the prescription.

  7. What's the Original Concept of Meridian and Acupuncture Point in Oriental Medicine? - A Perspective of Medical History

    Directory of Open Access Journals (Sweden)

    YIN Chang- Shik


    Full Text Available Meridian and acupuncture point(MAP is a core theory of acupuncture and essential building blocks of oriental medicine. There still continue theoretic or experimental arguments and controversies on the origination or original concept of MAP, without any definite approval or disapproval of a hypothesis. The theory of MAP is an historic product and has never been outside of historic influences. This study discusses the original concept of meridian and acupuncture point theory and its historical evolution, based on the review of classic literatures on meridian including the mawangdui medical texts of Han dynasty. The concept of MAP served as a empirical reference system in clinical settings irrespective of the anatomical entity of MAP.

  8. [SONG's theory on mast cells and meridian-acupoint and its research prospect]. (United States)

    Li, Yongming


    The historical origin of researches regarding acupuncture and mast cells (MCs) is reviewed, and the hypothesis that dermal MCs might be correlated with the acupuncture phenomena proposed by SONG Jimei in 1977 is introduced. This hypothesis, for the first time, suggests MCs could be the cellular basis of meridian sensation and arrival of qi ( deqi ) of acupoints. With independent tests of several research institutes, currently sufficient evidences prove the scientific values of SONG 's theory as well as its potential values for the basic research and clinical practice of acupuncture. It is reported recently that MCs might receive signals from central nerve system and acupoint stimulation, showing cross-talk effects, therefore, MCs can be sensitized at acupoints. In this paper, with a review of 40-year research evidence, 15 biological characteristics regarding mast cells and acupuncture phenomena are identified, in the meanwhile, 10 key questions and research direction, including the distribution of MCs in skin and its general relationship with meridian-acupoint, etc. are proposed.

  9. Interstitial Fluid Flow: The Mechanical Environment of Cells and Foundation of Meridians

    Directory of Open Access Journals (Sweden)

    Wei Yao


    Full Text Available Using information from the deep dissection, microobservation, and measurement of acupoints in the upper and lower limbs of the human body, we developed a three-dimensional porous medium model to simulate the flow field using FLUENT software and to study the shear stress on the surface of interstitial cells (mast cells caused by interstitial fluid flow. The numerical simulation results show the following: (i the parallel nature of capillaries will lead to directional interstitial fluid flow, which may explain the long interstitial tissue channels or meridians observed in some experiments; (ii when the distribution of capillaries is staggered, increases in the velocity alternate, and the velocity tends to be uniform, which is beneficial for substance exchange; (iii interstitial fluid flow induces a shear stress, with magnitude of several Pa, on interstitial cell membranes, which will activate cells and lead to a biological response; (iv capillary and interstitial parameters, such as capillary density, blood pressure, capillary permeability, interstitial pressure, and interstitial porosity, affect the shear stress on cell surfaces. The numerical simulation results suggest that in vivo interstitial fluid flow constitutes the mechanical environment of cells and plays a key role in guiding cell activities, which may explain the meridian phenomena and the acupuncture effects observed in experiments.

  10. [Study on characteristics of pharmacological effects of traditional Chinese medicines distributing along lung meridian based on medicinal property combination]. (United States)

    Gu, Hao; Zhang, Yan-Ling; Wang, Yun; Qiao, Yan-Jiang


    Medicinal properties are the basic attribute of traditional Chinese medicines (TCM), while the medicinal property theory is the core theoretical foundation of TCM formula combination. In this particle, authors studied the characteristics of pharmacological effects of property combination of traditional Chinese medicines distributing along meridians, with the aim to introduce the medicinal property combination regularity into the design and optimization process of compound TCMs, and bring the medicinal property theory into full play in guiding the formula combination. In this paper, TCMs distributing along "the lung meridian" was taken for example. The medicinal property combinations of TCMs distributing along "the lung meridian" recorded in Pharmacopeia (2010) was collected and processed. Besides, Chinese journal full-text database (CNKI) was used to collect all of pharmacological study literatures concerning the above TCMs that have been published since 1980. The pharmacological information was also supplemented by reference to Science of Chinese Materia Medica and Clinical Science of Chinese Materia Medica. TCMs distributing along the lung meridian with different properties and tastes showed significant differences in pharmacological effects. For example, mild-sweet-lung medicines could lower blood sugar levels, decrease anoxia and enhance immunity; Mild-bitter-lung medicines showed anti-bacterial, anti-hypertension, anti-oxidation effects; Hot-sweet-lung medicines showed antibechic and anti-bacterial effects. And Hot-bitter-lung medicines showed phlegm eliminating and anti-inflammatory effects. Meanwhile, TCMs distributing along the lung meridian had similar pharmacological characteristics, such as anti-bacterial and anti-inflammatory effects, which is consistent with lung's feature in susceptibility to exogenous pathogenic factors. In this study, authors discovered pharmacological characteristics of different TCMs distributing along the lung meridian, which

    Li, Su-Yun


    In the background of the spread of western medicine into the East in the Ming and Qing Dynasties, Chinese doctors who had accepted western medicine referred to western medical knowledge and began to use the methods of anatomical observation and demonstrating to explain the objective structure of meridians and collaterals. They tried to adopt the artery and vessel explaining the shape of meridian and the blood circle and pulmonary respiration explaining the circulation of Ying-Wei. When the anatomy structures could not perfectly equal to meridians and collaterals, some doctors put forward the gasification feature of meridian to explain the reason. These results suggest that there are difference between meridians and collaterals and pure anatomy concepts, which serves as significant reference and edification for later generations.

  13. Autonomous Sensory Meridian Response (ASMR: a flow-like mental state

    Directory of Open Access Journals (Sweden)

    Emma L. Barratt


    Full Text Available Autonomous Sensory Meridian Response (ASMR is a previously unstudied sensory phenomenon, in which individuals experience a tingling, static-like sensation across the scalp, back of the neck and at times further areas in response to specific triggering audio and visual stimuli. This sensation is widely reported to be accompanied by feelings of relaxation and well-being. The current study identifies several common triggers used to achieve ASMR, including whispering, personal attention, crisp sounds and slow movements. Data obtained also illustrates temporary improvements in symptoms of depression and chronic pain in those who engage in ASMR. A high prevalence of synaesthesia (5.9% within the sample suggests a possible link between ASMR and synaesthesia, similar to that of misophonia. Links between number of effective triggers and heightened flow state suggest that flow may be necessary to achieve sensations associated with ASMR.

  14. Sensory determinants of the autonomous sensory meridian response (ASMR): understanding the triggers. (United States)

    Barratt, Emma L; Spence, Charles; Davis, Nick J


    The autonomous sensory meridian response (ASMR) is an atypical sensory phenomenon involving electrostatic-like tingling sensations in response to certain sensory, primarily audio-visual, stimuli. The current study used an online questionnaire, completed by 130 people who self-reported experiencing ASMR. We aimed to extend preliminary investigations into the experience, and establish key multisensory factors contributing to the successful induction of ASMR through online media. Aspects such as timing and trigger load, atmosphere, and characteristics of ASMR content, ideal spatial distance from various types of stimuli, visual characteristics, context and use of ASMR triggers, and audio preferences are explored. Lower-pitched, complex sounds were found to be especially effective triggers, as were slow-paced, detail-focused videos. Conversely, background music inhibited the sensation for many respondents. These results will help in designing media for ASMR induction.

  16. Numerical simulation of the subsolar magnetopause current layer in the sun-earth meridian plane (United States)

    Okuda, H.


    The formation and stability of the magnetopause current layer near the subsolar point in the sun-earth meridian plane are examined using a 2D electromagnetic particle simulation. For the case of zero IMF, the simulation results show that the current layer remains stable and is essentially the same as in the 1D simulation. The width of the current layer is given by the electron-ion hybrid gyroradius which is much smaller than the ion gyroradius. The current layer is found to remain stable for the northward IMF as well. As in the 1D simulation, the jump of the magnetic field at the current layer for the northward IMF remains small. For the southward IMF, collisionless magnetic reconnection is found to develop, leading to the formation of magnetic islands and density peaking within the current layer.

  18. From Fragments to a museum display: restoration of a Gautier meridian circle (United States)

    Granato, Marcus


    The Museu de Astronomia e Ciências Afins (MAST), which opened to the public in 1985, is a research institute of the Brazilian Ministry of Science and Technology. One of its main activities is to preserve its collections, especially the most important one, its collection of scientific instruments, which grants MAST its identity as a museum of science and technology. Among the 2,000 objects in the collection there is a Gautier meridian circle that has a 190-mm diameter objective lens and a focal distance of 2,400 mm, with its axis aligned east-west. It should be noted that this instrument was at great risk of being lost to the collection, as it had been left dismantled since the 1960s, and the top part of the dome that sheltered it had been demolished in the 1980s, leaving just a vestibule and the base of the dome, which was in danger of completely collapsing. The intervention philosophy applied was not to put the instrument back in working order, but to allow it to be viewed and understood by the public within a coherent display space. As for the dome, a shelter was built for the instrument using a metal cover of a similar volume and appearance to the original, but with a different function, i.e. it is no longer designed to permit astronomical investigations, but rather to protect the exhibition space and merge harmoniously with the rest of the listed architectural complex. This paper presents information about the history of this meridian circle and its restoration, as well as about the Imperial Observatório do Rio de Janeiro/Observatório Nacional where this instrument was originally used.

  19. Trace elements in bottom sediments of the Barents Sea on the standard section "Kola Meridian"

    Directory of Open Access Journals (Sweden)

    Lapteva A. M.


    Full Text Available The levels of trace metals (Cu, Zn, Ni, Cr, Mn, Co, Pb, Cd, Hg and arsenic (As in samples of bottom sediments from the Barents Sea on eight stations of the standard section "Kola Meridian" have been investigated. Trace elements have been determined on atomic absorption spectrophotometer AA-6800 with mercury-hydride attachment HVG-1 of the company Shimadzu (Japan by the methods of flaming (acetylene – air and electrothermal atomization. Common and very toxic trace elements include Pb, Cd, As, and Hg. It is believed that 90 % of lead, 70–80 % of cadmium, and arsenic, over 30 % of mercury in the atmosphere are of anthropogenic origin, and emissions of these elements in the atmosphere are almost completely manufactured in the Northern Hemisphere. The main sources of income in the Barents Sea are waters of the North Atlantic current and the large-scale atmospheric transport from industrialized Central Europe. As a rule the spatial distribution of trace elements is in good agreement with the granulometric composition of bottom sediments and the content of organic carbon. The contents of most of the listed trace elements in samples of bottom sediments on the standard section "Kola Meridian" in the Norwegian classification are consistent with background levels with the exception of Ni, Cr, and As. Their content in bottom sediments at some stations has met the criteria for "slight" and "moderate" pollution. The obtained results confirm the insignificant levels of contamination of bottom sediments of some trace elements. On the status of stocks of commercial species of aquatic biological resources, the observed levels of contamination of bottom sediments in the investigated areas of the Barents Sea will have no significant effect

    Full Text Available In the paper the author presents overview of the meridian distance approximations. He would like to find the answer for the question what is actually the distance from the equator to the pole - the polar distance. In spite of appearances this is not such a simple question. The problem of determining the polar distance is a great opportunity to demonstrate the multitude of possible solutions in common use. At the beginning of the paper the author discusses some approximations and a few exact expressions (infinite sums to calculate perimeter and quadrant of an ellipse, he presents convenient measurement units of the distance on the surface of the Earth, existing methods for the solution of the great circle and great elliptic sailing, and in the end he analyses and compares geodetic formulas for the meridian arc length.

  2. Review of Evidence Suggesting That the Fascia Network Could Be the Anatomical Basis for Acupoints and Meridians in the Human Body

    Directory of Open Access Journals (Sweden)

    Yu Bai


    Full Text Available The anatomical basis for the concept of meridians in traditional Chinese medicine (TCM has not been resolved. This paper reviews the evidence supporting a relationship between acupuncture points/meridians and fascia. The reviewed evidence supports the view that the human body's fascia network may be the physical substrate represented by the meridians of TCM. Specifically, this hypothesis is supported by anatomical observations of body scan data demonstrating that the fascia network resembles the theoretical meridian system in salient ways, as well as physiological, histological, and clinical observations. This view represents a theoretical basis and means for applying modern biomedical research to examining TCM principles and therapies, and it favors a holistic approach to diagnosis and treatment.

  4. A single point acupuncture treatment at large intestine meridian: a randomized controlled trial in acute tonsillitis and pharyngitis. (United States)

    Fleckenstein, Johannes; Lill, Christian; Lüdtke, Rainer; Gleditsch, Jochen; Rasp, Gerd; Irnich, Dominik


    One out of 4 patients visiting a general practitioner reports of a sore throat associated with pain on swallowing. This study was established to examine the immediate pain alleviating effect of a single point acupuncture treatment applied to the large intestine meridian of patients with sore throat. Sixty patients with acute tonsillitis and pharyngitis were enrolled in this randomized placebo-controlled trial. They either received acupuncture, or sham laser acupuncture, directed to the large intestine meridian section between acupuncture points LI 8 and LI 10. The main outcome measure was the change of pain intensity on swallowing a sip of water evaluated by a visual analog scale 15 minutes after treatment. A credibility assessment regarding the respective treatment was performed. The pain intensity for the acupuncture group before and immediately after therapy was 5.6+/-2.8 and 3.0+/-3.0, and for the sham group 5.6+/-2.5 and 3.8+/-2.5, respectively. Despite the articulation of a more pronounced improvement among the acupuncture group, there was no significant difference between groups (Delta=0.9, confidence interval: -0.2-2.0; P=0.12; analysis of covariance). Patients' satisfaction was high in both treatment groups. The study was prematurely terminated due to a subsequent lack of suitable patients. A single acupuncture treatment applied to a selected area of the large intestine meridian was no more effective in the alleviation of pain associated with clinical sore throat than sham laser acupuncture applied to the same area. Hence, clinically relevant improvement could be achieved. Pain alleviation might partly be due to the intense palpation of the large intestine meridian. The benefit of a comprehensive acupuncture treatment protocol in this condition should be subject to further trials.

  5. An examination of the default mode network in individuals with autonomous sensory meridian response (ASMR). (United States)

    Smith, Stephen D; Katherine Fredborg, Beverley; Kornelsen, Jennifer


    Autonomous Sensory Meridian Response (ASMR) is a perceptual condition in which specific visual and auditory stimuli consistently trigger tingling sensations on the scalp and neck, sometimes spreading to the back and limbs. These triggering stimuli are often social, almost intimate, in nature (e.g., hearing whispering, or watching someone brush her hair), and often elicit a calm and positive emotional state. Surprisingly, despite its prevalence in the general population, no published study has examined the neural underpinnings of ASMR. In the current study, the default mode network (DMN) of 11 individuals with ASMR was contrasted to that of 11 matched controls. The results indicated that the DMN of individuals with ASMR showed significantly less functional connectivity than that of controls. The DMN of individuals with ASMR also demonstrated increased connectivity between regions in the occipital, frontal, and temporal cortices, suggesting that ASMR was associated with a blending of multiple resting-state networks. This atypical functional connectivity likely influences the unique sensory-emotional experiences associated with ASMR.

  6. An Examination of Personality Traits Associated with Autonomous Sensory Meridian Response (ASMR). (United States)

    Fredborg, Beverley; Clark, Jim; Smith, Stephen D


    Autonomous Sensory Meridian Response (ASMR) is a perceptual condition in which the presentation of particular audio-visual stimuli triggers intense, pleasurable tingling sensations in the head and neck regions, which may spread to the periphery of the body. These triggering stimuli are often socially intimate in nature, and usually involve repetition of movements and/or sounds (e.g., hearing whispering, watching someone brush her hair). Reports of ASMR experiences first appeared in online communities in 2010; since this time, these communities have expanded, with some groups consisting of over 100,000 members. However, despite the apparent prevalence of ASMR, there is currently no research on the personality characteristics that co-occur with this condition. In the current study, 290 individuals with ASMR and 290 matched controls completed the Big Five Personality Inventory (BFI; John et al., 1991); participants with ASMR also completed a questionnaire related to their ASMR phenomenology. Individuals with ASMR demonstrated significantly higher scores on Openness-to-Experience and Neuroticism, and significantly lower levels of Conscientiousness, Extraversion, and Agreeableness compared to matched controls. Further, ratings of subjective ASMR intensity in response to 14 common ASMR stimuli were positively correlated with the Openness-to-Experience and Neuroticism dimensions of the BFI. These results provide preliminary evidence that ASMR is associated with specific personality traits and suggest avenues for further investigation.

  7. Gnomon shadow lengths recorded in the Zhoubi Suanjing: the earliest meridian observations in China?

    International Nuclear Information System (INIS)

    Li Yong; Sun Xiaochun


    The Zhoubi Suanjing, one of the most important ancient Chinese books on mathematical astronomy, was compiled about 100 BC in the Western Han dynasty (BC 206 - AD 23). We study the gnomon shadow lengths for the 24 solar terms as recorded in the book. Special attention is paid to the so-called law of 'cun qian li', which says the shadow length of a gnomon of 8 chi (about 1.96 m) high will increase (or decrease) 1 cun (1/10 chi) for every 1000 li (roughly 400 km) the gnomon moves northward (or southward). From these data, one can derive the time and location of the observations. The results, however, do not fit historical facts. We suggest that compilers of the Zhoubi Suanjing must have modified the original data according to the law of 'cun qian li'. Through reversing the situation, we recovered the original data, our analysis of which reveals the best possible observation time as 564 BC and the location of observation as 35.78 deg. N latitude. We conclude that this must be the earliest records of solar meridian observations in China. In the meantime, we give the errors of solar altitudes for the 24 solar terms. The average deviation is 5.22 deg., and the mean absolute deviation is 5.52 deg., signifying the accuracy of astronomical calculations from that time.

  8. A birdcage model for the Chinese meridian system: part III. Possible mechanism of magnetic therapy. (United States)

    Yung, Kaung-Ti


    Based on the electromagnetic model of the transmission line for the channel and the birdcage resonator for the meridian network, we interpret two effects, seemingly incomprehensible in terms of current Western physiology, the lasting effect and the remote effect. For the lasting effect, acupuncture enhances the amplitude of the Qi standing wave, and this increased amplitude is retained and thus is able to sustain a gradual remodeling of the extracellular matrix in interstitial connective tissues, resulting in a lasting therapeutic effect. For the remote effect (acupuncture effect far from the site of needle insertion), our model puts the mechanism of magnetic therapy on an equal footing with that of acupuncture. It may not be a coincidence that accounts of investigators in both acupuncture and magnetotherapy about the depth of the effective site--along cleavage planes between muscles, or between muscle and bone or tendon--are in accord with that of the Huang Di Nei Jing about the course of channels: "they are embedded and travel between interstitial muscles, deep and invisible." A possible magnetic field generated outside the birdcage may be manipulated to produce local areas of higher temperature or very strong fields.

  9. Anders Celsius’ Contributions to Meridian Arc Measurements and the Establishment of an Astronomical Observatory in Uppsala

    Directory of Open Access Journals (Sweden)

    Stempels H. C.


    Full Text Available Astronomy has been on the curriculum of Uppsala University from at least the middle of the 15th century. However, since Uppsala also was the ecclesiastical centre of Sweden, the acceptance of new ideas, such as the Copernican heliocentric system, was slow. At the same time, more peripheral universities in the Swedish empire, including Dorpat/Tartu, enjoyed a larger freedom. It was not until the early 18th century that a ‘modern’ astronomy emerged in Uppsala. This effort was to a large extent led by Anders Celsius (1701-1744, who was able to establish good international contacts with astronomers in continental Europe. Celsius participated in De Maupertuis’ expedition to the far north of Sweden, in order to measure the meridian arc and determine the shape of the Earth. This paper explores how Celsius became involved in De Maupertuis’ expedition, and how this effort paved the way to the establishment of a fully equipped astronomical observatory, including an extensive collection of books and instruments, most of which survives up to this day.

  10. Acupuncture Treatment of Chronic Low Back Pain by Using the Jingjin (Meridian Sinews) Model. (United States)

    Legge, David


    This case report details the unexpected and sustained relief from chronic low back pain in a patient after a single acupuncture treatment. The treatment administered on that occasion was based on the jingjin (i.e., "meridian sinew") model of traditional acupuncture. Treatments based on the jingjin model involve needling the ah shi (i.e., locally tender) points in myofascial tissue along the jingjin pathway. Tight chains can be needled to treat symptoms that are either close to or at some distance from the site of the needling treatment. In this patient, the points were in the gastrocnemius muscle and the hamstring muscles, which are part of the Bladder jingjin pathway. The patient, a 69-year-old woman, had had back pain for more than 40 years. The relief from the pain occurred within a day after the treatment and, at the time of this report, the relief has persisted for 5 months. This report examines two possible mechanisms for such a result: (1) a local increase in the extensibility of the hamstrings could be responsible or (2) the complex interactions within the central nervous system that are involved in acupuncture treatment could be more important factors.

  11. The meridian system and mechanism of acupuncture: a comparative review. Part 3: Mechanisms of acupuncture therapies. (United States)

    Chang, Shyang


    The human body is a hierarchical organism containing many levels of mutually interacting oscillatory systems. From the viewpoint of traditional Chinese medicine, health is a state of harmony emergent from the interactions of these systems and disease is a state of discord. Hence, human diseases are considered as disturbed functions rather than changed structures. Indeed, the change from normal to abnormal structure may be beneficent rather than maleficent. For example, when one kidney becomes twice the normal size following the destruction of the other kidney, it is good and not bad for us because we might be dead otherwise. Therefore, in Part 3 of this three-part series, emphasis is mainly laid on the acupuncture mechanisms of treating disturbed physiological functions rather than disordered structures. At first, the basic tenets of conventional neuroscience and cardiology are reevaluated so that clear understanding of how nervous and cardiovascular systems work together can be obtained. Then, the general principles of diagnosis and treatment in traditional Chinese medicine from the integrative perspective of complex dynamic systems are proposed. Finally, mechanisms of acupuncture therapies for treating 14 different categories of disorders will be elucidated via the magneto-electric inductive effects of the meridian system. Copyright © 2013.

  12. [From Bonghan system to primo vascular system:the thought on the substantial study on meridian points]. (United States)

    Lin, Dong; Huang, Xiaozhen; Zhuang, Wanyu; Lin, Lili


    Through the systematic analysis on the primo vascular system (PVS) in recent years, we believe that in recent years, more and more studies have indicated that PVS is distributed in reticulate structure in every part of body, such as vessels, lymphangions, nerves, brain, spinal cords and internal organs, and it contains a large amount of immunocytes and has involved in the physiological or pathological process of the immunity and circulation in the body. There are the evidences to prove that in morphology and cytobiology. But, nowadays, there is no way to explain its effect characters. On the basis of the study on living matter characteristics, a breakthrough is possibly made through the systematic cooperation even though it is the difficulty to detect the life function effect. It is especially displayed in the substantial study on meridian points. Hence, the study on the law of meridian point effects on the basis of clinical practice has to be focused on in the substantial study on meridian points.

  13. [Study on pharmacologic action characteristics of traditional Chinese medicines distributed along liver meridian based on medicinal properties combinations]. (United States)

    Guo, Hong-Ling; Gu, Hao; Wang, Yun; Qiao, Yan-Jiang


    To establish a characterization system of traditional Chinese medicinal properties in line with modern scientific cognition regularity, in order to reveal properties of traditional Chinese medicines distributed along liver meridian and relations of effects of medicinal properties. By collecting data about traditional Chinese medicinal properties recorded in the Pharmacopoeia of the People's Republic of China (2005 Edition), literature and data about pharmacological effects of traditional Chinese medicines recorded in the Chinese Materia Medica, by using the method of association rules, the authors dug pharmacological effect rules corresponds to relevant medicinal property combinations, with the medicinal property combination of traditional Chinese medicines distributed along liver meridian as the target. It was found that either obvious different pharmacological effects or identical pharmacological characteristics existed in traditional Chinese medicines distributed along liver meridian. With the aim to explore the correlations between traditional Chinese medicine medicinal properties and pharmacological effects, the authors linked the traditional Chinese medicine theory with modern research achievements, in order to provide the ideas and methods for interpreting mechanisms of medicinal properties.

  14. Structural Dynamics in Metal Tris-hydroxyquinolines: Interconversion of Meridianal and Facial Alq3 Isomers (United States)

    Ferris, Kim; Sapochak, Linda; Burrows, Paul; Rodovsky, Deanna; Marmolejo, Theresa


    While previous work investigating the charge transport properties of Alq3 has indicated that the meridianal (mer) conformation of Alq3 is predominant species, recent work suggesting identification of a facial (fac) form raises again the question of heterogeneity. Electronic structure computations from our group have noted that the energy difference(in parenthesis) between the mer and fac conformations is highly sensitive to basis set description (8.6 kcal/mol//3-21g*/SCF; 6.9 kcal/mol//6-31g*/SCF), electron correlation (6.0 kcal/mol//3-21g*/MP2; 4.7 kcal/mol//6-31g*/MP2), and solvent effects (4.4 kcal/mol/3-21g*/SCF/DMSO). Given these small energy differences, we have conducted a series of Hartree-Fock and first principles electronic structure computations on the interconversion of these structural forms, and will report on the structural and energetic aspects of the transformation. The likely reaction path involves lengthening of the Al-N bond to the point where a pentacoordinate intermediate or transition state would be formed, followed by flipping of the ligand through rotation around the Al-O bond. Following Schmidbauer's earlier work, we note that transformation involving only one ligand will actually lead to a facial isomer. Preliminary characterization of this transition state suggests that the activation energy is approximately 20-25 kcal/mol above the mer conformation.

    Functional dyspepsia (FD) is a common disease without an established optimal treatment. To determine (i) the effect of acupuncture in relieving FD symptoms and improving life quality; (ii) the effect difference between acupoint and non-acupoint; and (iii) the effect difference among different acupoints. A total of 712 eligible patients were included and randomly assigned to six groups (Group A: specific acupoints of the stomach meridian; Group B: non-specific acupoints of the stomach meridian; Group C: specific acupoints of alarm and transport points; Group D: specific acupoints of the gallbladder meridian; Group E: sham acupuncture of non-acupoints; and Group F: itopride). A treatment period of 4 weeks (continuous five sessions per week), and a follow-up period of 12 weeks were arranged. The outcomes were the (i) patients' response, (ii) symptoms improvement measured using the Symptom Index of Dyspepsia and (iii) quality-of-life improvement based on Nepean Dyspepsia Index. All groups had an improvement in dyspepsia symptoms and the QoL at the end of treatment, and the improvement was sustained for 4 weeks and 12 weeks. The overall response rate was significantly higher in acupuncture group A (70.69%), and lower in sham acupuncture group (34.75%), compared with itopride and other acupuncture groups. Similarly, the difference in symptoms and QoL improvement was significant between group A and the other acupuncture groups. Acupuncture is effective in the treatment of functional dyspepsia, and is superior to non-acupoint puncture. The benefit of acupuncture relies on acupoint specificity. © 2012 Blackwell Publishing Ltd.

  16. On the evaluation of the capacitance of toroidal capacitors with a moon-shape meridian cross section

    International Nuclear Information System (INIS)

    Gongora T, A.; Ley-Koo, E.


    The toroidal capacitors studied in this paper consist of electrodes with meridian cross sections that are circular arcs meeting at the axis, and separated from each other by two small insulating spheres at their meeting points. The description and analysis of such capacitors is carried out by using bi spherical coordinates. The R-separability of the Laplace equation in these coordinates requires the use of the Green function technique, just like in the related problems of toroidal, spherical-cap-electrode, and bi spherical capacitors (1-3). An overall comparison of the solutions of the four problems is specially instructive. (Author)

  17. Probing the mystery of Chinese medicine meridian channels with special emphasis on the connective tissue interstitial fluid system, mechanotransduction, cells durotaxis and mast cell degranulation

    Directory of Open Access Journals (Sweden)

    Fung Peter


    Full Text Available Abstract This article hypothesizes that the Chinese medicine meridian system is a special channel network comprising of skin with abundant nerves and nociceptive receptors of various types, and deeper connective tissues inside the body with the flowing interstitial fluid system. These meridian channels provide efficient migratory tracks mainly due to durotaxis (also including chemotaxis for mast cells, fibroblasts and other cells to migrate and carry out a number of physiological functions. Acupuncture acting on meridian channel causes cytoskeletal remodeling through mechanotransduction, leading to regulation of gene expression and the subsequent production of related proteins. Also, stimulation on cell surface can trigger Ca2+ activities, resulting in a cascade of intra- and inter-cellular signaling. Moreover, nerve endings in the meridian channels interact with mast cells and induce the degranulation of these cells, leading to the release of many specific biomolecules needed for homeostasis, immune surveillance, wound healing and tissue repair. Acupoint along a meridian channel is a functional site to trigger the above functions with specificity and high efficiency.

  18. Anatomical Features of the Interscapular Area Where Wet Cupping Therapy Is Done and Its Possible Relation to Acupuncture Meridians. (United States)

    Ghods, Roshanak; Sayfouri, Nasrin; Ayati, Mohammad Hossein


    Although wet cupping has been a treatment for centuries, its mechanism of action is not well understood. Because the anatomical features of the wet-cupping area might play a role in its mechanism, we focus on the features of the interscapular area in which a common type of wet-cupping therapy (WCT), called Hijamat-e-Aam in Iranian medicine, is usually applied and discuss the possible relation of those features to the acupuncture meridians. We gathered and analyzed data from reliable textbooks on modern medicine with a focus on the anatomical features of the interscapular area, topics related to WTC in Iranian medicine, and acupuncture sources obtained by searching PubMed, Google-Scholar, and Science Direct. The interscapular area used for WCT was found to have special features: brown adipose tissue, immediate proximity to sympathetic ganglia, passage of the thoracic duct, two important acupuncture meridians, and proximity to the main vessel divisions carrying blood from the heart and the brain. These features indicate that the interscapular application of WCT not only discharges waste materials through a shifting of blood to the site after application of a traction force but also invigorates the body's metabolism, increases immunity, and regulates blood biochemistry, which are desired therapeutic effects of WCT.

  20. Refractive variation under accommodative demand: curvital and scaled torsional variances and covariance across the meridians of the eye. (United States)

    van Gool, R D; Harris, W F


    Autorefractor measurements were taken on the right eye of 10 students with an external target at vergences -1.00 and -3.00 D. The refractive errors in the form of sphere, cylinder, and axis were converted to vectors h and variance-covariance matrices calculated for different reference meridians. Scatter plots are drawn in symmetric dioptric power space. The profiles of curvital and scaled torsional variances, the scaled torsional fraction, and the scaled torsional-curvital correlation are shown using a polar representation. This form of representation provides a meridional pattern of variation under accommodative demand. The profile for scaled torsional variance is characteristically in the form of a pair of rabbit ears. At both target vergences curvital variance is larger than scaled torsional variance in all the meridians of the eye: the relative magnitudes are quantified by the scaled torsional fraction. An increase in accommodative demand generally results in an increase in variance. The rabbit ears usually become larger but less well divided. The correlation between curvital and torsional powers is usually positive in the first quadrant and negative in the second quadrant. Typical, atypical, and mean typical responses are discussed.

    To observe the impacts of the intervention with electric thermal bian stone and air suction cup on blood perfusion (BP) at meridian points and explore the approach of accurate measurement and regulation of meridian qi and blood balance in "precise acupuncture". The laser Doppler line scanner (LDLS) was used to measure BP at bilateral yua n-primary points at the pericardium meridian, the triple energizer meridian, the gallbladder meridian and the liver meridian (small cycle of jueyin to shaoyang meridians) at 31 healthy receptors. The bias ratio of blood perfusion (BPBR) deviated to the reference value was calculated. The electric thermal bian stone and air suction cup were used in the intervention at the he -sea points of the affected meridians in which BPBR was relatively higher at the yuan -primary points. The electric thermal bian stone therapy was used when BPBR was less than -30% and the air suction cupping therapy was used when BPBR was higher than 30%. BP was measured twice before intervention and it was measured separately at the moment after intervention and in 20 min after intervention. The means of BP before and after intervention and the change ratio of blood perfusion (BPCR) before intervention, at the moment after intervention and 20 min after intervention were calculated. 1. After the intervention of electric thermal bian stone, BP mean was increased from (103.51±41.21) PU to (121.97±56.22) PU ( P 0.05), but the change ratio was highly remained. 2. After intervention with air suction cup, BP mean was reduced from (194.83±81.14) PU to (173.88±88.26) PU. Before intervention, at the moment after intervention and 20 min after intervention, separately, BPCR were (7.62±30.49)%, (-12.12±18.20)% and (-14.35±21.25)%. BPCR at the moment after intervention and in 20 min after intervention were significantly different from that before intervention (both P cup is opposite.

    To study the antirheumatic substance of Loranthus parasiticus and observe the relationship between its in vivo distribution and meridian tropism in rats by establishing adjuvant arthritis models corresponding to effectiveness. All rats except the negative control group were injected with 0.1 mL Freund's complete adjuvant on the left foot. After 8 days, the rats in negative control group and model group were given with normal saline while the rats in positive control group were given with tripterygium glycosides suspension 10 mg•kg-1, and the rats in L. parasiticus treatment groups were given with high(10 g•kg ⁻¹), medium(5 g•kg ⁻¹) and low(2.5 g•kg ⁻¹) dose decoction for 21 days. The left rear ankle joint diameter of rats were measured every 7 days from the 9th day of modeling. On the 22nd day, eyeball blood of part rats in L. parasiticus high-dose group was taken at different time points, and then they were sacrificed to take heart, liver, spleen, lung, kidney, stomach, large intestine, small intestine and brain tissues. For the remaining rats, eyeball blood was taken 30 min after drug treatment, and their left rear ankle joints were taken to detect interleukin (IL)-1β and tumor necrosis factor (TNF)-α levels in serum by ELISA method; rutin, avicularin and quercitrin levels in the tissues of high-dose group were detected by HPLC; pharmacokinetic parameters were analyzed by using DAS 2.0. Our results showed that L. parasiticus decoction could significantly improve the paw edema situation of adjuvant arthritis model rats, and reduce IL-1β and TNF-α levels in rat serum. The in vivo efficacy substance analysis in rats showed that rutin was only present in the stomach with a small amount. AUC0-t of avicularin was stomach > small intestine > kidney, and the duration time in vivo was kidney=stomach > small intestine > lung > heart. AUC0-t of quercitrin was stomach > kidney > liver > heart > lung > spleen > small intestine > brain > large intestine

  7. Moxibustion in Early Chinese Medicine and Its Relation to the Origin of Meridians: A Study on the Unearthed Literatures

    Directory of Open Access Journals (Sweden)

    Chang Huang


    Full Text Available Moxibustion is an integral part of Traditional Chinese Medicine (TCM. It achieved higher level of recognition and had more general application in ancient times than in contemporary life. As the vital historical sources, the records of unearthed literatures offered precious insights to Chinese social life pattern and medical practice in Qin and Han dynasties (221 BC–220 AD. There was no surprise that the bamboo and silk documents excavated from Mawangdui (马王堆 tomb, Hantanpo (旱滩坡 tomb, and other relics had a large amount of texts relevant to moxibustion. This research sorted moxibustion recordings from seven unearthed literatures and discovered that moxibustion had been developed into different modalities and utilized to treat many diseases at that time. In addition, the indications, contraindications of moxibustion, and the method of postmoxibustion care were also discussed. On this basis, some hints were provided to support the hypothesis that the practice of moxibustion led to the discovery of meridians. All our preliminary results in the research have drawn attention for this old therapy and given a new source for its application in clinic and scientific research.

    Bombi Lee


    Full Text Available Acupuncture is an ancient therapeutic intervention that can be traced back at least 2100 years and is emerging worldwide as one of the most widely used therapies in the field of complementary and alternative medicine. Due to limitations associated with Western medicine's focus on the treatment of diseases rather than on their causes, interests are shifting to complementary and alternative medicines. The Acupuncture and Meridian Science Research Center (AMSRC was established in 2005 to elucidate the neurophysiological mechanisms of acupuncture for neurological diseases based on multidisciplinary research supported by the Korean Ministry of Science and Technology. In the AMSRC, resultant research articles have shown that acupuncture can improve neurological and psychological problems, including Parkinson's disease, pain, and depression, in animal models. Basic research studies suggest its effectiveness in treating various problems such as depression, drug addiction, epilepsy, ischemia, dementia, Parkinson's disease, and pain. We strongly believe that these effects, evident from the AMSRC research results, can play leading roles in the use of acupuncture for treating neurological diseases, based on collaboration among various academic fields such as neurophysiology, molecular genetics, and traditional Korean medicine.

  9. [Observation on changes of oxygen partial pressure in the deep tissues along the large intestine meridian during acupuncture in healthy subjects]. (United States)

    Chen, Ming; Hu, Xiang-long; Wu, Zu-xing


    To observe changes of the partial oxygen pressure in the deep tissues along the Large Intestine Meridian (LIM) during acupuncture stimulation, so as to reveal the characteristics of energy metabolism in the tissues along the LIM. Thirty-one healthy volunteer subjects were enlisted in the present study. Partial oxygen pressure (POP) in the tissues (at a depth of about 1.5 cm) of acupoints Binao (LI 14), Shouwuli (LI 13), Shousanli (LI 10), 2 non-acupoints [the midpoints between Quchi (LI 11) and LI 14, and between Yangxi (LI 5) and LI 11) of the LIM, and 10 non-meridian points, 1.5-2.0 cm lateral and medial to each of the tested points of the LIM was detected before, during and after electroacupuncture (EA) stimulation of Hegu (LI 4) by using a tissue oxygen tension needle-like sensor. In normal condition, the POP values in the deep tissues along the LIM were significantly higher than those of the non-meridian control points on its bilateral sides. During and after EA of Hegu (LI 4), the POP levels decreased significantly in the deep tissues along the LIM in comparison with pre-EA (P 0.05). POP is significantly higher in the deep tissues along the LIM of healthy subjects under normal conditions, which can be downregulated by EA of Hegu (LI 4), suggesting an increase of both the utilization rate of oxygen and energy metabolism after EA.

  10. Closing the Knowledge Gap: Effects of Land Use Conversion on Belowground Carbon near the 100th Meridian (United States)

    Waldron, S. E.; Phillips, R. L.; Dell, R.; Suddick, E. C.


    Native prairie of the northern Great Plains near the 100th meridian is currently under land use conversion pressure due to high commodity prices. From 2002 to 2007, approximately 303,515 hectares of prairie were converted to crop production in the Prairie Pothole Region (PPR) from Montana to the Dakotas. The spatiotemporal effects of land-use conversion on soil organic matter are still unclear for the PPR. Effects will vary with management, soil properties and time, making regional experiments and simulation modeling necessary. Grassland conservationists are interested in soil carbon data and soil carbon simulation models to inform potential voluntary carbon credit programs. These programs require quantification of changes in soil carbon associated with land-use conversion and management. We addressed this issue by 1) designing a regional-scale experiment, 2) collecting and analyzing soil data, and 3) interviewing producers about land management practices, as required for regional, process-based biogeochemical models. We selected farms at random within a 29,000 km2 area of interest and measured soil properties at multiple depths for native prairie and adjacent annual crop fields. The cores were processed at six different depths (between 0 and 100 cm) for bulk density, pH, texture, total carbon, inorganic carbon, and total nitrogen. We found that the largest difference in soil organic carbon occurred at the 0-10 cm depth, but the magnitude of the effect of land use varied with soil properties and land management. Results from this project, coupled with regional model simulations (Denitrification-Decomposition, DNDC) represent the baseline data needed for future voluntary carbon credit programs and long-term carbon monitoring networks. Enrollment in such programs could help ranchers and farmers realize a new income stream from maintaining their native prairie and the carbon stored beneath it.

  11. Acupuncture Effect on Pain, Mouth Opening Limitation and on the Energy Meridians in Patients with Temporomandibular Dysfunction: A Randomized Controlled Trial

    Directory of Open Access Journals (Sweden)

    Vera LR. Zotelli


    Full Text Available Temporomandibular disorders (TMD, recognized as the most common conditions of chronic orofacial pain, have a multifactorial etiology. Acupuncture can help to relieve the pain and discomfort associated with these conditions, because it can rebalance the energy (Qi circulating in the meridians. The aim of the study was to verify the effectiveness of acupuncture in treating the pain; mouth opening limitation, and energy circulating in the meridians of patients with TMD of muscular or mixed origin. This was a controlled, randomized, double-blind clinical trial conducted at the Piracicaba Dental School (FOP/Unicamp, in Piracicaba SP, Brazil. The Treatment Group received acupuncture with real penetration of the needle, and the Placebo Group received a sham treatment without needle penetration. The acupoints used were: ST6, ST7, SI18, GV20, GB20, BL10, and LI4, during treatment performed for four weekly sessions. The TMD and mouth opening were evaluated according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC. The measurements of the energy at the meridians were performed by the Ryodoraku method, before and after acupuncture in all of the sessions in both groups.

  12. Observation of intensity of cosmic rays and daily magnetic shifts near meridian 70° in the South America (United States)

    Cordaro, E. G.; Gálvez, D.; Laroze, D.


    In analysis of experiments carried during September 2008 using secondary cosmic ray detectors located in Chacaltaya (Bolivia) and Niteroi (Brazil), Augusto et al. (2010) showed an increase in the intensity of charged particles which takes place 3 h after sunrise and lasts until 1 h after sunset, furthermore they said that during this period the solar magnetic field lines overtake the Earth‧s surface. These stations are located within the South Atlantic Magnetic Anomaly (SAMA), having both different magnetic rigidities. To reproduce data from the Niteroi and Chacaltaya stations, we record data during the same hours and days using our neutron monitors, muon telescopes and magnetometers within the stations Putre and Los Cerrillos. Our observation stations in Putre and Cerrillos are located at 18°11‧47.8″S, 69°33‧10.9″W at an altitude of 3600 m and 33°29‧42.3″S, 70°42‧59.81″W with 570 m height above sea level, respectively. These stations are located within the South Atlantic Anomaly (SAMA) and are separated approximately 1700 km from each other and 1700 km from the center of the anomaly. Our network is composed furthermore by two auxiliary Cosmic Ray and/or Geomagnetic stations located at different latitudes along 70°W meridian, LARC and O'Higgins stations, which are located within Antarctic territory, covering a broad part of the Southern Hemisphere. Our magnetometer data shows that for each of the components, shifts in the magnetic field intensity for every station (even for those out of the SAMA) lasted between 3 and 4 h after sunrise and 1 and 2 h past sunset, which are the periods when the geomagnetic field is modulated by the transit of the dayside to nightside and nightside to dayside. We believe that, although the magnetometric data indicates the magnetic reconnection for the Chilean region, there is no direct influence from the SAMA other than the lower rigidity cut-off that leads to an increased count rate.

    In this article, natural rubber is chosen as transitional layer of all-steel load meridian tyre, which is pre-vulcanized by 500 keV E-beam irradiation of up to 60 kGy. The results show that the Green strength of transitional layer increases with the dose, reaching four times at 60 kGy as much as the control (without irradiation). The viscosity of transitional layer increases rapidly below about 29 kGy, but changes little at higher doses. The final mechanical properties do not differ significantly from those of the control. However, thickness of the natural rubber transitional layer for an average single tire can be reduced by 1 mm (or 1.5 kg), without obvious adverse effect on the tyre performance. (authors)

  14. Stratum Corneum Hydration and Skin Surface pH Variation Indicate that Organ Blood Flow Is Regulated by Meridian Activity at Certain Hours

    Full Text Available Day and night are regular occurrences in nature, and the organs and tissues in living bodies follow this cycle. The sympathetic nervous system (SNS at various time points regulates organ excitation to maintain healthy functions in the living body. The energy required from basal metabolism can be used to explain living organisms according to the traditional Chinese medicine (TCM concept of relationships between meridian directions and organs at various times (organs “at rest” and organs “in operation”. By monitoring skin reactions after applying a cream, we speculated regular blood flow changes, and established an animated hourglass-shaped trajectory diagram to visualize these changes. A combination of TCM and physiological perspectives were considered to explain how the cardiovascular system produces energy. These two perspectives were applied to interpret the correlation between the SNS and organ metabolism.

    This literary analysis expands the scholarly canon concerning Cormac McCarthy’s regional writing by identifying the purpose of pictographs and petroglyphs in Blood Meridian or the Evening Redness in the West (1985). Not only do pictographs and petroglyphs tie the narrative to place, but they create a commentary regarding the erasure of Native American histories in the United States. These images record Native American memory and presence in the landscape, and by referencing them, McCarthy con...

  16. Examining the Electric Fields of the Evening Equatorial Ionosphere When the Solar Terminator is Aligned and Not Aligned with the Magnetic Meridian (United States)

    Eccles, J. V.


    The electric field structure of the equatorial ionosphere near sunset has implications on the development of plasma irregularities. The details of the development of the electric fields are examined using a global ionosphere-electrodynamics model. The results of simulations of simplified conditions show the influence of the arrangement of the solar terminator with the magnetic meridian. The relationships of the Curl-Free mechanism, the Hall Current Divergence mechanism, and the role of the Equatorial Electorjet region control the magnitude and timing of the Prereversal Enhancement of the zonal electric field as well as its altitude profile above the F region bottomside. Realistic conditions for 'equinox' and 'solstice' solar terminator arrangments are presented. The stability of the low-latitude ionosphere has a demonstrated relationship with the solar terminator alignment [Tsunoda, JGR, 1981]. The profile of the vertical and zonal electric field below the bottomside is then examined using the global model to explore the controlling elements of the electric field structure and the growth rates of the Rayleigh-Taylor instability and Collisional Shear instability.Tsunoda, R.

  19. Characteristics of Total Electron Content (TEC) observed from a chain of stations near the northern crest of the Equatorial Ionization Anomaly (EIA) along 88.5°E meridian in India (United States)

    Paul, K. S.; Das, A.; Ray, S.; Paul, A.


    The equatorial ionosphere presents some of the highest TEC values in the world coupled with observations of periodic structures. Total Electron Content (TEC) and scintillation data were analyzed from a chain of stations Calcutta (22.58°N, 88.38°E geographic; 32°N magnetic dip), Baharampore (24.09°N, 88.25°E geographic; 35°N magnetic dip) and Farakka (24.79°N, 87.89°E geographic; 36.04°N magnetic dip) situated almost same meridian (88.5°E) during September 2011 and March-April 2012 for elevation greater than 20° so that the ionosphere can be tracked from the 15.50°N south of Calcutta to 31.80°N north of Farakka. Periodic variation of TEC was noticed before TEC bite out, predominantly within a particular latitudinal swath (19°N ‒26°N) along 88.5°E meridian. No periodic structures were observed over the magnetic equator during the observation period on ionosonde records from the magnetic equator station Trivandrum and COSMIC, GRACE and C/NOFS electron density measurements. The present paper reports, perhaps for the first time from the Indian longitude sector, confinement of such periodic structures in TEC primarily within a latitude swath of 19.00-26.00 °N almost along the same longitude of 88.5 °E.

  20. Modelling of the meridian flow in nominal and partial flow in axial and helico-centrifugal turbomachinery; Modelisation en regime nominal et partiel de l'ecoulement meridien dans les turbomachines axiales et helicocentrifuges

    Energy Technology Data Exchange (ETDEWEB)

    Ercolino, J.


    In this study, a fast analysis code for the meridian flow inside turbo-machineries has been developed. This code is based on the resolution of the averaged dynamical equations controlling the internal stationary and non-viscous flow in the relative reference frame. A linear combination of momentum equations has been used in the axial and radial directions to avoid the source term of the equations to become singular. The model developed is particularly adapted to the general case of compression machines, i.e.the mixed machines. Starting with the hypothesis of a finite number of blading and assuming an axisymmetric flow, the equations allowing to calculate the blading forces and the simplified kinematics of blade-to-blade flow have been developed. This kinematics takes into consideration the geometrical data supplied by manufacturers or by global design softwares. This last approach ensures a very efficient link in the framework of turbomachine design projects where the blades geometry is introduced in a very simple way for a first optimization approach. The results obtained seem to be very consistent in nominal flow but also in partial flow conditions as shown by the qualitative comparisons with test results. (J.S.)

    Energy Technology Data Exchange (ETDEWEB)


    The Burnt Timber Creek map-area lies in the southern Foothills of Alberta and includes a narrow strip of the Front Range of the Rocky Mts. along its western edge. The area may be divided into 3 principal structural units, underlain from west to east by the McConnell, Burnt Timber, and Fallentimber thrusts, respectively. McConnell thrust underlies the eastern edge of the mountains. Subsidiary folding and faulting are locally evident in the Paleozoic strata above the thrust. Beneath the McConnell thrust, Mesozoic and Paleozoic strata of the Burnt Timber thrust sheet are strongly overturned in the Panther anticline. The axis of this anticline trends northwest. A culmination along it, in the vicinity of Sheep Creek, deforms the McConnel thrust as well. A total of 16 wells have been drilled to date in 4 separate groups. Each group has revealed the presence of gas and 8 of the wells have been capped as potential gas producers. The reservoir rocks are of Mississippian and Devonian age. Shell Panther River No. 1 well (5-19-30-10W5) is remarkable in having tested at about 86% hydrogen sulfide.

    Full Text Available Field surveys were conducted along 140°E in the Southern Ocean north of Terre Adelie during three cruises: the KH cruise by RV Hakuho Maru, and TC1 and TC2 cruises by RV Tangaroa during the austral summers of 2002 and 2003. Macrozooplankton were sampled using a Rectangular Midwater Trawl (RMT 8: mesh size: 4.5mm; effective mouth area: 8m2 along each transect. Macrozooplankton communities were separated by the Southern Boundary of the Antarctic Circumpolar Current (SB-ACC based on cluster analysis. North of the SB-ACC, macrozooplankton assemblages comprised species of the northern oceanic community characterized by Salpa thompsoni, Euphausia frigida and Themisto gaudichaudii, while south of the SB-ACC, macrozooplankton assemblages were numerically dominated by Euphausia superba and/or Euphausia crystallorophias. It is suggested that the SB-ACC functions as the major biogeographic barrier to separate the macrozooplankton communities, and the contributions of macro- and meso-zooplankton to total zooplankton abundance varies seasonally as well as regionally in the Indian sector of the Southern Ocean crossing the SB-ACC.

  12. The Meanings and Prospects of Primo Vascular System from the Viewpoint of Historical Context

    Directory of Open Access Journals (Sweden)

    Jongwook Jeon


    Full Text Available The aim of this overview is to evaluate the primo vascular system research in the context of the history of meridian theory and the modern meanings of it. The 12 meridian systems were naturally presupposed in the conventional study of the meridians and acupuncture. But the excavations of Mawang-tui old documents and Sichuan Mianyang wooden puppet revealed the primordial concepts of meridians uncolored by the numerological cosmology of Han era. Further, the meridian map of horse, cow and hawk show another resemblance to the primordial type of meridians. Modern meridian theory has been challenged by the material based scientific theory and the primo vascular theory presents the most radical answer for it. It aims to reveal the anatomical entity of meridians. However, the study of primo vascular system is unexpectedly opening the new horizon of scientific integration of East and West beyond the mere searching for anatomical entity of meridians. Conclusions we have drawn from the historical reviews are, (1 the surface structure of the body reflects the physiopathological changes of inside the body, (2 by stimulating specific sites on the surface, it is possible to acquire therapeutic effects of certain symptoms, and (3 numbers and locations of meridian acupoints are variable among traditional meridian theories.

  5. [Theoretical origin and clinical application of wrist-ankle acupuncture therapy]. (United States)

    Wang, Qiong; Zhou, Qinghui


    The theory of wrist-ankle acupuncture is consistent with traditional meridian-collateral theory. For example, the body divisions of wrist-ankle acupuncture are corresponding to the distribution of 12 cutaneous regions of meridians, the needling sites of it are to the running courses of 12 meridians; the indications of it are to those of 12 meridians. The needling sites of wrist-ankle acupuncture are relevant with some special acupoints of acupuncture theory. For example, the 12-needling sites of wrist-ankle acupuncture are located similar to those of 12 meridian points and have very similar indications. The needling sites of it are located in the wrist and ankle regions, in which the five- shu points are located nearby, for meridian disorders. Most luo -connecting points are located near to the needling sites of wrist-ankle acupuncture or the needle tip points to. Additionally, the needling method of wrist-ankle acupuncture is consistent with some of the subcutaneous needling methods in traditional acupuncture therapy. On the basis of the aspects mentioned above, it is explained that wrist-ankle acupuncture is the development of traditional acupuncture and cannot be independent from the traditional theories of acupuncture and meridians. It is necessary to seek for the evidence from the traditional theories of TCM. The traditional theories of TCM are summarized from clinical practice, which can be newly verified from the practice of wrist-ankle acupuncture.

    The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.

    As one of the important founders of GAO's acupuncture academic school in YanZhao area, Professor GAO Yuchun 's experience of acupuncture for headache is summarized in this paper. In the opinion of Professor GAO, the treatment of headache should focus on eliminating evil and relieving pain, and the syndrome differentiation should be based on meridian differentiation, especially on three yang meridians of foot as well as liver meridian and kidney meridian. In the acupoint prescription, attention should be placed on strengthening the spleen and stomach. The midnight-midday ebb flow acupuncture is advocated. The combination between acupuncture order and movement of qi is emphasized. In the manipulation, the role of pressing hand, the stimulation during reinforcing and reducing methods, and needle-retention time are important. The breathing reinforcing and reducing method of acupuncture are also advocated.

    Directory of Open Access Journals (Sweden)

    Andréia Mitidieri


    Full Text Available Objectives: This study used semiology based on traditional Chinese medicine (TCM to investigate vital energy (Qi behavior in women with abdominal myofascial pain syndrome (AMPS. Methods: Fifty women diagnosed with chronic pelvic pain (CPP secondary to AMPS were evaluated by using a questionnaire based on the theories of “yin-yang,” “zang-fu”, and “five elements”. We assessed the following aspects of the illness: symptomatology; specific location of myofascial trigger points (MTrPs; onset, cause, duration and frequency of symptoms; and patient and family history. The patients tongues, lips, skin colors, and tones of speech were examined. Patients were questioned on various aspects related to breathing, sweating, sleep quality, emotions, and preferences related to color, food, flavors, and weather or seasons. Thirst, gastrointestinal dysfunction, excreta (feces and urine, menstrual cycle, the five senses, and characteristic pain symptoms related to headache, musculoskeletal pain, abdomen, and chest were also investigated. Results: Patients were between 22 and 56 years old, and most were married (78%, possessed a elementary school (66%, and had one or two children (76%. The mean body mass index and body fat were 26.86 kg/ cm2 (range: 17.7 — 39.0 and 32.4% (range: 10.7 — 45.7, respectively. A large majority of women (96% exhibited alterations in the kidney meridian, and 98% had an altered gallbladder meridian. We observed major changes in the kidney and the gallbladder Qi meridians in 76% and 62% of patients, respectively. Five of the twelve meridians analyzed exhibited Qi patterns similar to pelvic innervation Qi and meridians, indicating that the paths of some of these meridians were directly related to innervation of the pelvic floor and abdominal region. Conclusion: The women in this study showed changes in the behavior of the energy meridians, and the paths of some of the meridians were directly related to innervation of the

  5. Music acupuncture stimulation method. (United States)

    Brătilă, F; Moldovan, C


    Harmonic Medicine is the model using the theory that the body rhythms synchronize to an outer rhythm applied for therapeutic purpose, can restores the energy balance in acupuncture channels and organs and the condition of well-being. The purpose of this scientific work was to demonstrate the role played by harmonic sounds in the stimulation of the Lung (LU) Meridian (Shoutaiyin Feijing) and of the Kidney (KI) Meridian (Zushaoyin Shenjing). It was used an original method that included: measurement and electronic sound stimulation of the Meridian Entry Point, measurement of Meridian Exit Point, computer data processing, bio feed-back adjustment of the music stimulation parameters. After data processing, it was found that the sound stimulation of the Lung Meridian Frequency is optimal between 122 Hz and 128 Hz, with an average of 124 Hz (87% of the subjects) and for Kidney Meridian from 118 Hz to 121 Hz, with an average of 120 Hz (67% of the subjects). The acupuncture stimulation was more intense for female subjects (> 7%) than for the male ones. We preliminarily consider that an informational resonance phenomenon can be developed between the acupuncture music stimulation frequency and the cellular dipole frequency, being a really "resonant frequency signature" of an acupoint. The harmonic generation and the electronic excitation or low-excitation status of an acupuncture point may be considered as a resonance mechanism. By this kind of acupunctural stimulation, a symphony may act and play a healer role.

  6. Electrodermal Screening of Asthmatics with AcuGraph 4

    Directory of Open Access Journals (Sweden)

    Kuntal Ghosh


    Full Text Available Traditional Chinese Medicine holds that acupuncture meridian activity is correlated with quality of function of specific organs. This study sets out to determine acupuncture meridian characteristics of subjects with moderate asthma distinguishing them from healthy subjects. Fifty asthma patients (age 35.36 ± 8.68 years and fifty similarly aged (34.11 ± 7.29 years healthy volunteers were enrolled in the study. Electrodermal conductances at Jing Well points were measured with Acugraph 4 and also Peak Expiratory Flow Rate (PEFR for the asthma group. All mean meridian conductances were lower for the asthma group, significance differences were in Lung and right Bladder meridians. In contrast, all but two of the standard deviations of group meridian conductances for the Asthma group were higher than those for the Healthy group. Difference in mean PEFR values between Asthma and Healthy groups was significant. These suggest that group measures of electrical conductance at Jing Well points can distinguish asthma from healthy individuals. The study provides support for the usefulness of meridian energy measurements to assess organ related dysfunction and for the idea that pathology groups exhibit higher standard deviations i.e. lower quality of regulation.

  7. Surgical correction of postoperative astigmatism

    Directory of Open Access Journals (Sweden)

    Lindstrom Richard


    Full Text Available The photokeratoscope has increased the understanding of the aspheric nature of the cornea as well as a better understanding of normal corneal topography. This has significantly affected the development of newer and more predictable models of surgical astigmatic correction. Relaxing incisions effectively flatten the steeper meridian an equivalent amount as they steepen the flatter meridian. The net change in spherical equivalent is, therefore, negligible. Poor predictability is the major limitation of relaxing incisions. Wedge resection can correct large degrees of postkeratoplasty astigmatism, Resection of 0.10 mm of tissue results in approximately 2 diopters of astigmatic correction. Prolonged postoperative rehabilitation and induced irregular astigmatism are limitations of the procedure. Transverse incisions flatten the steeper meridian an equivalent amount as they steepen the flatter meridian. Semiradial incisions result in two times the amount of flattening in the meridian of the incision compared to the meridian 90 degrees away. Combination of transverse incisions with semiradial incisions describes the trapezoidal astigmatic keratotomy. This procedure may correct from 5.5 to 11.0 diopters dependent upon the age of the patient. The use of the surgical keratometer is helpful in assessing a proper endpoint during surgical correction of astigmatism.

  8. An Acupuncture Research Protocol Developed from Historical Writings by Mathematical Reflections: A Rational Individualized Acupoint Selection Method for Immediate Pain Relief

    Directory of Open Access Journals (Sweden)

    Sven Schroeder


    Full Text Available While balancing yin and yang is one basic principle of Chinese medicine, balancing methods for combination of meridians and acupoints had been described throughout the history of Chinese medicine. We have identified six historical systems for combinations of acupuncture points in historical writings. All of them represent symmetrical combinations which are defined by the steps in the Chinese Clock. Taking the historical systems as a basis, we calculated the possible combinations that fit into these systems they revealed, leading to a total of 19 systems offering new balancing combinations. Merging the data of these 19 systems, there are 7 combinatorial options for every meridian. On the basis of this data, we calculated 4-meridian combinations with an ideal balance pattern, which is given when all meridians balance each other. We identified 5 of these patterns for every meridian, so we end up with 60 patterns for all the 12 meridians but we find multiple overlapping. Finally, 15 distinct patterns remain. By combining this theoretical concept with the Image and Mirror Concept, we developed an acupuncture research protocol. This protocol potentially solves some problems of acupuncture trials because it represents a rational reproducible procedure independent of examiner experience, but the resulting treatment is individualized.

  9. Investigation of Acupuncture Sensation Patterns under Sensory Deprivation Using a Geographic Information System (United States)

    Beissner, Florian; Marzolff, Irene


    The study of acupuncture-related sensations, like deqi and propagated sensations along channels (PSCs), has a long tradition in acupuncture basic research. The phenomenon itself, however, remains poorly understood. To study the connection between PSC and classical meridians, we applied a geographic information system (GIS) to analyze sketches of acupuncture sensations from healthy volunteers after laser acupuncture. As PSC can be subtle, we aimed at reducing the confounding impact of external stimuli by carrying out the experiment in a floatation tank under restricted environmental stimulation. 82.4% of the subjects experienced PSC, that is, they had line-like or 2-dimensional sensations, although there were some doubts that these were related to the laser stimulation. Line-like sensations on the same limb were averaged to calculate sensation mean courses, which were then compared to classical meridians by measuring the mean distance between the two. Distances ranged from 0.83 cm in the case of the heart (HT) and spleen (SP) meridian to 6.27 cm in the case of the kidney (KI) meridian. Furthermore, PSC was observed to “jump” between adjacent meridians. In summary, GIS has proven to be a valuable tool to study PSC, and our results suggest a close connection between PSC and classical meridians. PMID:23243458

  10. ZONE, Finite Elements Method Quadrilateral and Triangular Mesh Generator for 2-D Axisymmetric Geometry

    International Nuclear Information System (INIS)

    Burger, M. J.


    1 - Description of problem or function: The ZONE program is a finite element mesh generator which produces the nodes and element description of any two-dimensional geometry. The geometry is divided into a mesh of quadrilateral and triangular zones defined by node points taken in a counter-clockwise sequence. The zones are arranged sequentially in an ordered march through the geometry. The order can be chosen so that the minimum bandwidth is obtained. The mesh that is generated can be used as input to any two-dimensional as well as any axisymmetrical structure program. 2 - Method of solution: The basic concept used is the definition of a two-dimensional structure by the intersection of two sets of lines which describe the geometric and material boundaries. A set of lines called meridians define the geometric and material boundaries and generally run in the same direction. Another set of linear line segments called rays which intersect the meridians are also defined at the material and geometric boundaries. The section of the structure between successive rays is called a region. The ray segment between any two consecutive ray-meridian intersections or void area in the structure is called a layer and is described as passing through, or bounding a material. The boundaries can be directly defined as a sequence of straight line segments or can be computed in terms of elliptic segments or circular arcs. A meridian or ray can also be made to follow a previously-defined meridian or ray at a fixed distance by invoking an offset option. 3 - Restrictions on the complexity of the problem: The following are limited only by a DIMENSION statement. The code currently has a maxima of: 100 coordinate points defining a meridian or ray, 40 meridians, 40 layers. There are no limits on the number of zones or nodes for any problems

  11. Visual acuity outcomes in eyes with flat corneas after PRK. (United States)

    Varssano, David; Waisbourd, Michael; Minkev, Liza; Sela, Tzahi; Neudorfer, Meira; Binder, Perry S


    To evaluate the impact of corneal curvatures less than 35 diopters (D) after photorefractive keratectomy (PRK) on visual acuity outcomes. Visual acuity outcomes of 5,410 eyes that underwent PRK from January 2006 to November 2010 were retrospectively analyzed for the impact of postoperative corneal curvatures on visual outcomes. All procedures were performed on a single platform (Allegretto 200Hz excimer laser; Alcon Laboratories, Inc., Irvine, CA). Main outcome measures were postoperative corrected distance visual acuity (CDVA) and loss of CDVA. Corneas with a measured or a calculated postoperative flat meridian less than 35 D and those with a measured postoperative steep meridian less than 35 D had worse postoperative CDVA than corneas with meridians of either 35 D or more (P ≤ .021). However, the preoperative CDVA was worse in the flatter curvatures in all comparisons performed (P ≤ .024). Consequently, the measured or calculated meridian curvature had no effect on CDVA loss (P ≥ .074). Postoperative corneal keratometry values (flat and steep meridians) less than 35 D did not have a predictive effect on the risk of losing visual acuity following myopic PRK performed on the Allegretto 200Hz excimer laser.

  12. [Study on the excavated wooden carved acupuncture statue of the Western Han Dynasty in Laoguanshan]. (United States)

    Huang, L X


    The painted red lines on the wooden carved acupuncture statue of Western Han Dynasty in Laoguanshan, illustrate the running courses of the"eleven meridians"on the body surface in the early meridian doctrine. The carved white lines show the body surface running courses of the"twelve meridians"in the meridian doctrine and the Sanjiao images in Sanjiao doctrine. The dots on the wooden carved acupuncture statue are of two categories, one of them is of regulatory, round and concave spots, which are carved before the process of lacquer undercoat. The other category is of different sizes and in irregular forms, which are carved simultaneously with those white lines. Altogether there are over one hundred dots in these two categories, representing the mai shu (transport point of vessels). The wooden carved acupuncture statue reflects the distinct characteristics on the running courses of meridians, Sanjiao doctrine, the nomenclature and localization of" mai shu "in Bianque medicine, which provides the most powerful evidence for the confirmation of the correlation between Laoguanshan excavated documents and Bianque medicine.

  13. Exogenous and endogenous spatial attention effects on visuospatial working memory. (United States)

    Botta, Fabiano; Santangelo, Valerio; Raffone, Antonino; Lupiáñez, Juan; Belardinelli, Marta Olivetti


    In this study, we investigate how exogenous and endogenous orienting of spatial attention affect visuospatial working memory (VSWM). Specifically, we focused on two attentional effects and their consequences on storage in VSWM, when exogenous (Experiment 1) or endogenous (Experiment 2) orienting cues were used. The first effect, known as the meridian effect, is given by a decrement in behavioural performance when spatial cues and targets are presented in locations separated by vertical and/or horizontal meridians. The second effect, known as the distance effect, is given by a decrement in the orienting effects as a function of the spatial distance between cues and targets. Our results revealed a dissociation between exogenous and endogenous orienting mechanisms in terms of both meridian and distance effects. We found that meridian crossing affects performance only when endogenous cues were used. Specifically, VSWM performance with endogenous cueing depended more on the number of meridian crossings than on distance between cue and target. By contrast, a U-shaped distance dependency was observed using exogenous cues. Our findings therefore suggest that exogenous and endogenous orienting mechanisms lead to different forms of attentional bias for storage in VSWM.

  14. A Chinese Decoction, Kuan-Sin-Yin, Improves Autonomic Function and Cancer-Related Symptoms of Metastatic Colon Cancer. (United States)

    Chien, Tsai-Ju; Liu, Chia-Yu; Ko, Pin-Hao; Hsu, Chung-Hua


    Kuan-Sin-Yin (KSY) is a traditional Chinese medicine (TCM) decoction, which has been shown to have cytostatic effects on cancer cells and involved in the TCM theory of promoting yin-yang balance.Sonce many cancer patients suffer from autonomic dysfunction (AD), which correspond to yin-yang imbalance in TCM. The aim of this study is to evaluate the possible effect of KSY in metastatic colon cancer (mCRC) patients with AD. We conducted a single-group experiment. Total 52 qualified patients were enrolled. Participants took the KSY daily for 2 weeks. The primary outcome was KSY efficacy as reflected in the heart rate variability (HRV) and electrical conductivity (µA) over 12 meridian points. Autonomic function was examined before and after the KSY intervention. The vagal and sympathetic tone were recorded by HRV; 12 meridian energies were measured using a meridian energy analysis device. Secondary outcomes were cancer-related symptoms and patient quality of life (QoL). The results showed that the KSY intervention improved AD via increasing the vagal tone (HF: P = .041), but not the sympathetic tone (LF: P = .154); total autonomic activity was significantly enhanced (HRV activity: P = .013). Intriguingly, energy increased more over the yin meridian (P = .010) than over the yang meridian (P = .015). Cancer-related symptoms and QoL were significantly improved (P yin-yang concept of energy. © The Author(s) 2015.

  15. Dynamics of the dayside aurora

    International Nuclear Information System (INIS)

    Creutzberg, F.; Mcewen, D.J.


    A clearer picture of the dynamical nature of the post-noon aurora has been obtained with instrumental studies during rocket flights over the Northwest Territories of Canada. A sequence of meridian scans showing the measured intensities of the emissions along the meridian from south to north is presented. An all-sky picture of an auroral event is presented which shows a very narrow arc running through the zenith in an east-west direction, typical of many occurring during the period 1-3 hrs after local magnetic noon. A contemporaneous meridian scan taken over the same location shows a narrow spike in the zenith. The frequent occurrence of these narrow, transient auroral arcs with lifetimes of 1-2 minutes, resulting from inverted V events, is discussed

  17. The Geopolitics of Tropical Diseases A Geo - epidemiological Perspective

    Directory of Open Access Journals (Sweden)

    LEE Jong- Chan


    Full Text Available Meridian and acupuncture point(MAP is a core theory of acupuncture and essential building blocks of oriental medicine. There still continue theoretic or experimental arguments and controversies on the origination or original concept of MAP, without any definite approval or disapproval of a hypothesis. The theory of MAP is an historic product and has never been outside of historic influences. This study discusses the original concept of meridian and acupuncture point theory and its historical evolution, based on the review of classic literatures on meridian including the mawangdui medical texts of Han dynasty. The concept of MAP served as a empirical reference system in clinical settings irrespective of the anatomical entity of MAP.

  18. Therapeutic efficacy of Traditional Chinese medicine, "Kuan-Sin-Yin", in patients undergoing chemotherapy for advanced colon cancer - A controlled trial. (United States)

    Chien, Tsai-Ju; Liu, Chia-Yu; Lu, Ruey-Hwa; Kuo, Chin-Wei; Lin, Yang-Chao; Hsu, Chung-Hua


    Traditional Chinese Medicine (TCM) has been used increasingly as complementary medicine in cancer care. Kuan-Sin-Yin (KSY) is a TCM decoction containing seven herbs known to cause immunomodulation or anticancer activity, and which are associated with the TCM concept of Qi and energy supply. Kuan-Sin-Yin has cytostatic effects on cancer cells in animal models. The aim of this study is to evaluate the level of improvement in meridian energy and heart-rate variability (HRV) and to assess whether these observations are compatible with TCM theory. A non-randomized controlled trial was designed with monitoring of the meridian electro-conductivity and heart-rate variability (HRV) to compare the efficacy of Kuan-Sin-Yin in the control and experimental groups. 52 patients were enrolled in this study. We also measured cancer-related symptoms and quality of life as secondary outcomes. We found that colon cancer patients who received KSY as complementary therapy benefitted with enhancement of meridian energy (Yin meridian: 27.90:35.45μA; p=0.014; Yang meridian: 27.09:33.55μA; p=0.024) and increases in HRV activity (78.40:129.04ms; SDNN: p=0.001) and parasympathetic tone(HF:1644.80:3217.92 ms 2 ; p=0.003; RMMSD:99.76:164.52ms; p=0.002). Cancer-related symptoms decreased (ECOG>1:46.2:7.7%; p=0.0001), and quality of life (KSY group: PCS 35.46:42.12, p=0.0001; MCS: 44.50:47.55, p=0.209) was improved with statistical significance. The correlation of positive results reflected in meridian energy and HRV activity confirms the positive role of complementary medicine of Kuan-Sin-Yin in cancer care. Copyright © 2016 Elsevier Ltd.

    Chen, Min; Wu, Changqiu; Wu, Xueyi


    Numerology has a long history in China and has the profound impacts on every academic field in TCM, with acupuncture involved. In this paper, the impacts on acupuncture were discussed in different aspects such as the numbers of meridians, the length of meridian, the time taboo of acupuncture, acupuncture manipulation and time acupuncture. It was found that numerology had laid the critical impact on acupuncture and had the profound imprint nowadays. It is of great significance to study the numerology theory in its impacts on acupuncture, in the exploration on the theories behind acupuncture as well as the comprehensive understanding of acupuncture.

  1. [Characteristics of acupoint application for the sub-healthy condition treated with ancient and modern acupuncture based on data mining exploration]. (United States)

    Cai, Liyan; Wu, Jie; Ma, Tingting; Yang, Lijie


    The acupoint selection was retrieved from the ancient and modern literature on the treatment of sub-healthy condition with acupuncture. The law of acupoint application was analyzed so as to provide a certain reference to the determination of acupoint prescription in clinical acupuncture. The ancient literature was retrieved from Chinese basic ancient literature database. The modern literature was retrieved from Cochrane Library, Medline, PubMed, Ovid evidence-based medicine database, Chinese biomedical literature database, China journal full-text database, VIP journal full-text database and Wanfang database. The database mining software was adopted to explore the law of acupoint application in treatment of sub-healthy conditions with ancient and modern acupuncture.

  2. Partial Fourier analysis of time-harmonic Maxwell's equations in axisymmetric domains

    International Nuclear Information System (INIS)

    Nkemzi, Boniface


    We analyze the Fourier method for treating time-harmonic Maxwell's equations in three-dimensional axisymmetric domains with non-axisymmetric data. The Fourier method reduces the three-dimensional boundary value problem to a system of decoupled two-dimensional boundary value problems on the plane meridian domain of the axisymmetric domain. The reduction process is fully described and suitable weighted spaces are introduced on the meridian domain to characterize the two-dimensional solutions. In particular, existence and uniqueness of solutions of the two-dimensional problems is proved and a priori estimates for the solutions are given. (author)

  3. Radar measurements of the latitudinal variation of auroral ionization

    International Nuclear Information System (INIS)

    Vondrak, R.R.; Baron, M.J.


    The Chatanika, Alaska, incoherent scatter radar has been used to measure the spatial variation of auroral ionization. A two-dimensional (altitude, latitude) cross-sectional map of electron densities in the ionosphere is produced by scanning in the geomagnetic meridian plane. The altitutde variation of ionization is used to infer the differential energy distribution of the incident auroral electrons. The latitudinal variation of this energy distribution and the total energy input are obtained by use of the meridian-scanning technique. Examples are shown of observations made during an active aurora

    Wang, Wenjie; Du, Yanjun


    The Akabane's test is one of the meridian diagnostic methods. Compared with the current meridian diagnostic methods, it has the advantages of convenience and efficiency, but it also has several disadvantages such as the accuracy is difficult to control, the outcome interpretation is limited, etc. In this paper, the influence factors of Akabane's test were analyzed one by one, especially proposed personal opinion on outcome interpretation, which could ascertain the location and nature of disease, leading to disease syndrome. With accurate syndrome, the treatment plan could be established. The application prospect of Akabane's test was initially explored, and it was proposed that wearable automation equipment could be one of the development directions.

  5. Postherpetic Neuralgia: Practical Experiences Return to Traditional Chinese Medicine

    Directory of Open Access Journals (Sweden)

    Majid Avijgan


    In traditional medicine (TM, PHN is mostly due to incomplete heat and damp clearing in liver and spleen meridians, qi and toxic pathogens stagnation, accumulation of yin (blood stagnation in microcapillary, internal fire, and heat and obstruction of meridians. Acupuncture works based on the eradication of wind, clearing of heat, and destroying of damp by regulating qi and blood movement. In clinics, several methods of TM are used to relief PHN, such as simultaneous needling, surrounding needling, acupuncture, electro acupuncture, moxibustion, wet cupping or hijamat, and herbal medicine. In this review, we discussed all these methods and their role in reducing PHN and pain.

  6. The origin of luminescence blueshifts in Alq{sub 3} composites

    Recently, tris(8-hydroxyquinoline)aluminum (Alq{sub 3}) has been diluted into various sol-gel matrices, and a strong blueshift with respect to the well-known emission band of amorphous thin films has been observed. This result has been explained by the absence of interactions among molecules that are isolated in the microscopic pores of glasses. The same explanation is also working in analogous measurements performed lately in various matrices, where the blueshift was wrongly attributed to a mixing of facial and meridianal isomers. Indeed, it is shown here that the Alq{sub 3} meridianal isomer alone can explain the experimental results.

    Johnson, J.J.; Charman, C.M.


    A general isoparametric shell of revolution finite element subjected to any order harmonic loading is presented. Derivation of the element properties, its implementation in a general purpose finite element program, and its application to a sample problem are discussed. The element is isoparametric, that is, the variation of the displacements along the meridian of the shell and the shape of the meridian itself are approximated in an identical manner. The element has been implemented in the computer program MODSAP. A sample problem of a cooling tower subjected to wind loading is presented. (orig./HP)

  4. Automatic diagnostic system for measuring ocular refractive errors (United States)

    Ventura, Liliane; Chiaradia, Caio; de Sousa, Sidney J. F.; de Castro, Jarbas C.


    Ocular refractive errors (myopia, hyperopia and astigmatism) are automatic and objectively determined by projecting a light target onto the retina using an infra-red (850 nm) diode laser. The light vergence which emerges from the eye (light scattered from the retina) is evaluated in order to determine the corresponding ametropia. The system basically consists of projecting a target (ring) onto the retina and analyzing the scattered light with a CCD camera. The light scattered by the eye is divided into six portions (3 meridians) by using a mask and a set of six prisms. The distance between the two images provided by each of the meridians, leads to the refractive error of the referred meridian. Hence, it is possible to determine the refractive error at three different meridians, which gives the exact solution for the eye's refractive error (spherical and cylindrical components and the axis of the astigmatism). The computational basis used for the image analysis is a heuristic search, which provides satisfactory calculation times for our purposes. The peculiar shape of the target, a ring, provides a wider range of measurement and also saves parts of the retina from unnecessary laser irradiation. Measurements were done in artificial and in vivo eyes (using cicloplegics) and the results were in good agreement with the retinoscopic measurements.

  5. Computer analysis of multicircuit shells of revolution by the field method

    International Nuclear Information System (INIS)

    Cohen, G.A.


    The method of analysis developed which has been termed the 'field method' converts the boundary-value problem into two successive initial-value problems. In the first initial-value problem, a forward integration over the shell meridian is made for the 'field functions', which may be interpreted physically as influence functions (plus additional functions to account for external loading) of the structure. The second initial-value problem consists of a backward integration (i.e., in the reverse direction) for the physical force and displacement functions, the differential equations for which are dependent on the already calculated field functions. In this method, no artificial subdivision of the meridian is necessary since both initial-value problems are numerically stable. Also, because the physical response functions are obtained directly from the backward integration, their storage points may be chosen automatically during execution to obtain a uniformly 'dense' description of these functions. Studies comparing the efficiency (i.e., execution time) of the field method with that of a conventional superposition (Zarghamee) method have been made, for the simple case of the linear static response of a clamped cylindrical shell. The field method has been presented previously for shells of revolution with open branched meridians. This work is now extended to the case of meridians which contain circuits. Also, a new method for the treatment of arbitrary kinematic constraints is presented

  6. [Nomenclature of Feiyang (BL 58) and its connotation exploration based on A-B Classic of Acupuncture and Moxibustion]. (United States)

    Feng, Shuangshuang; Hou, Zhongwei


    A - B Classic of Acupuncture and Moxibustion ( Zhen Jiu Jia Yi Jing ) is the earliest and existed well-known work on acupuncture and moxibustion, with irreplaceable literature values and huge impacts on the later generations. Feiyang (BL 58) is the luo -connecting point of the bladder meridian and recorded 11 times in A - B Classic of Acupuncture and Moxibustion . This book is the representative for the exploration on the acupoint nomenclature and clinical connotation. Through the investigation on the textual connotation of the specified terms and the alias of Feiyang (BL 58), it was discovered that the nomenclature of this acupoint was based on the main symptoms, the characters of the running course of meridian and acupuncture effects. It was proved that the unique property of this acupoint was as rising, dispersing and flying of meridian qi . In comparison of Huangdi Three - Version of A - B Classic of Acupuncture and Moxibustion ( Huangdi Sanbu Zhen Jiu Jia Yi Jing ) of the printed edition of the Song Dynasty version and Meridian - Collateral and Acupoints ( Zhen Jiu Shu Xue Xue ), it was found that the indications and connotation of Feiyang (BL 58) were more extensively richer than the records in teaching materials. Those study results contribute to the extension of the clinical application of this acupoint.

  13. Global Space Weather Observational Network: Challenges and China's Contribution (United States)

    Wang, C.


    To understand space weather physical processes and predict space weather accurately, global space-borne and ground-based space weather observational network, making simultaneous observations from the Sun to geo-space (magnetosphere, ionosphere and atmosphere), plays an essential role. In this talk, we will present the advances of the Chinese space weather science missions, including the ASO-S (Advanced Space-borne Solar Observatory), MIT (Magnetosphere - Ionosphere- Thermosphere Coupling Exploration), and the ESA-China joint space weather science mission SMILE (Solar wind - Magnetosphere - Ionosphere Link Explore), a new mission to image the magnetosphere. Compared to satellites, ground-based monitors are cheap, convenient, and provide continuous real-time data. We will also introduce the Chinese Meridian Project (CMP), a ground-based program fully utilizing the geographic location of the Chinese landmass to monitor the geo-space environment. CMP is just one arm of a larger program that Chinese scientists are proposing to the international community. The International Meridian Circle Program (IMCP) for space weather hopes to connect chains of ground-based monitors at the longitudinal meridians 120 deg E and 60 deg W. IMCP takes advantage of the fact that these meridians already have the most monitors of any on Earth, with monitors in Russia, Australia, Brazil, the United States, Canada, and other countries. This data will greatly enhance the ability of scientists to monitor and predict the space weather worldwide.

  1. Yin and yang surfaces: an evolutionary perspective. (United States)

    Legge, David


    A search of the Chinese medicine literature reveals several conflicting explanations of the division of the body into yin and yang surfaces. This paper attempts to clarify this basic concept and reconcile the differing descriptions of it through an exploration of material from other disciplines. A remarkable similarity exists between the surfaces on the human body that are defined by the pathways of the yin and yang meridians and those that have evolved from the ventral and the dorsal aspects of early vertebrate structure. Many of the evolutionary changes described have parallels in our embryological development and are evident in the underlying anatomy of our limbs. The degree of convergence between the two descriptions strongly supports the definition of the yin and yang surfaces as those traversed by the yin and yang meridians. It also goes a long way towards reconciling the conflicting definitions found in the literature. Finding a solution to this question of yin and yang surfaces that is based on anatomy and evolutionary theories has several advantages. It can throw light on differences in the clinical effects of points on the yin and yang meridians and enable the identification of anomalies in the pathways of the main meridian network.

    The paper aimed to elucidate the specific impact of supramolecular chemistry on the Chinese medicine theories (CMT) in their modernization, after had summarized up the research status of supramolecular chemistry and analyzed the possible supramolecular forms of Chinese medicine (CM), as well as considered the problems in modernization of CM theories. On comparison of the classical chemistry that delt with chemical bonds among atoms, the supramolecular chemistry was rather concerned with varietes of weak noncovalent bonds intermolecules, and reflected the macro-apparent chemical properties of each molecules, and was the most appropriate chemical theories to explain the CMT and microcosmic materials. The molecules in the human body and Chinese material medica (CMM) formed supramolecules by way of self-assembly, self-organization, self-recognition and self-replication, with themselves or with complexation, composition, chelation, inclusion, neutralization etc. Meridian and Zang-fu viscera in CMT might be a space channel structure continuously consisted of unique molecules cavity that was imprinted with the supramolecularly template inside and outside of cells, through which the molecules in CMM interacted with the meridian and Zang-fu viscera. When small molecules in human body imprinted with macromolecules in meridian and Zang-fu viscera, in other words, they migrated along within imprinting channels of meridian and Zang-fu viscera on behavior of "Qi chromatography" impulsed by the heart beat, finally showed up on macroscopic the anisotropy of tissue and organ, as described namely as visceral manifestation in Chinese medical science. When small molecules in CMM interacted with imprinting channel on meridian and Zang-fu viscera, the natural properties and efficacy regularities of CMM was reflected on macroscopic. Therefore, the special representation forms of basic CMT is based on the macroscopic expression of "Qi chromatography" abided by imprinting effect

  2. Astrometry and early astrophysics at Kuffner Observatory in the late 19th century (United States)

    Habison, Peter

    The astronomer and mathematician Norbert Herz encouraged Moriz von Kuffner, owner of the beer brewery in Ottakring, to finance a private scientific observatory in the western parts of Vienna. In the years 1884-87 the Kuffner Observatory was built at the Gallitzinberg in Wien-Ottakring. It was an example of enlighted patronage and noted at the time for its rapid acquisition of new instruments and by increasing international recognition. It contained the largest heliometer in the world and the largest meridian circle in the Austrian-Hungarian Empire. Of the many scientists who worked here we mention Leo de Ball, Gustav Eberhard, Johannes Hartmann and we should not forget Karl Schwarzschild. Here in Vienna he published papers on celestial mechanics, measuring techniques, optics and his fundamental papers concerning photographic photometry, in particular the quantitative determination of the departure of the reciprocity law. The telescope and the associated camera with which he carried out his measurements are still in existence at the observatory. The observatory houses important astronomical instruments from the 19th century. All telescopes were made by Repsold und Söhne in Hamburg, and Steinheil in Munich. These two German companies were best renowned for quality and precision in high standard astronomical instruments. The Great Refractor (270/3500 mm) is still the third largest refractor in Austria. It was installed at the observatory in 1886 and was used together with the Schwarzschild Refractor for early astrophysical work including photography. It is this double refractor, where Schwarzschild carried out his measurements on photographic photometry. The Meridian Circle (132/1500 mm) was the largest meridian passage instrument of the Austro-Hungarian Empire. Today it is the largest meridian circle in Austria and still one of the largest in Europe. The telescope is equipped with one of the first impersonal micrometers of that time. First observations were carried

  3. [Acupuncture therapy for regaining consciousness in terms of acupoint location, needle insertion and needle manipulation]. (United States)

    Meng, Xianggang; Gu, Wenlong; Ma, Fen; Du, Yuzheng; Zhao, Qi


    Acupuncture therapy for regaining consciousness activates soreness, numbness, distention, heaviness, radiating and moving, electric shock and ant climbing sensations at the specific acupoints in the stroke patients. Radiating and moving sensations are the summary of needling sensations such as soreness, numbness and twitching presenting during lifting and thrusting manipulation. These sensations are the essential factors of the therapeutic effect of regaining consciousness. Radiating sensation refers to the conduction along meridians and radiation of soreness and numbness. Moving sensation refers to the local muscular twitching at acupoints and the involuntary movement of limbs, joints and the distal. Acupuncture at the specific acupoints achieves radiating and moving sensations for promoting the circulation in meridians, regulating qi and mind and balancing yin and yang in stroke patients. This therapy was introduced in the paper in view of acupoint location, needle insertion and manipulation.

  4. [Preliminary study on syndrome differentiation types and acupuncture for whiplash injuries]. (United States)

    Chen, Ye-meng; Li, Hui; Zheng, Xin; Zhang, Qun-ce; Wang, Tian-fang


    Whiplash injury is a relatively common injury of clinical acupuncture and moxibustion in the United States. The mechanism and clinical manifestation of whiplash injuries as well as its pathogenesis described in TCM were analyzed in this present article. The authors introduced the TCM syndrome differentiation of whiplash injuries and claimed that both the location and the stage of disease should be considered. For the different injury locations, the meridian musculature differentiation was applied to classify the whiplash injuries as Taiyang, Yangming, Shaoyang and Shaoyin Meridian syndromes. Considering the duration of the injury, qi stagnation and blood stasis types were classified in the acute stage and phlegm accumulation, insufficiency of the liver and kidney and qi and blood deficiencies types were classified during the chronic stage. An acupuncture protocol for whiplash injuries and typical cases were also introduced.

  5. Optical properties of nonimaging concentrators with corrugated reflectors (United States)

    Roennelid, Mats; Perers, Bengt; Karlsson, Bjorn


    A ray tracing study has been performed on the optical properties of cylindrical nonimaging concentrators with linear corrugated reflectors. The corrugations are assumed to be V-formed and to have an extension parallel to the meridian plane of the concentrators. It is shown that the acceptance angle for radiation incident in the meridian plane can be increased for moderate corrugations. This increased acceptance is balanced by a decreased acceptance of radiation from other directions. Calculations of angular acceptance for a 2X compound parabolic concentrator is presented. It is shown that the annual irradiation on a solar collector with booster reflector can be increased if corrugated reflectors are used instead of smooth reflectors.

    Wang, Shaosong


    By using the methods of experience summary and case report, professor WANG Linpeng 's clinical experience of acupuncture for migraine was summarized.Professor WANG proposed the different acupuncture plans should be established according to the active stage and remission stage of migraine; in the active stage acupuncture should be applied at gallbladder meridian with penetration needling technique to reinforce the stimulation intensity; in the remission stage the aim was to regulate zang-fu and back- shu points should be emphasized.In addition, attention should be paid on acupuncture technique and preventive treatment.For menstruation-type and psychological disorder-type migraine, different acupuncture plans should be adopted and regulating meridian and spirit was essential in the treatment.

  7. [Summary of professor YANG Jun's experience for intractable facial paralysis]. (United States)

    Wang, Tao; Li, Zaiyuan; Ge, Tingqiu; Zhang, Man; Yuan, Aihong; Yang, Jun


    Professor YANG Jun 's experience of diagnosis and treatment for intractable facial paralysis is introduced. Professor YANG focuses on the thinking model that combines TCM, western medicine and acupuncture, and adopts the differentiation system that combines disease differentiation, syndrome differentiation and meridian differentiation; he adopts the treatment integrates etiological treatment, overall regulation, symptomatic treatment as well as acupuncture, moxibustion, medication and flash cupping. The acupoints of yangming meridians are mostly selected, and acupoints of governor vessel such as Dazhui (GV 14) and Jinsuo (GV 8) are highly valued. The multiple-needles shallow-penetration-insertion twirling lifting and thrusting technique are mostly adopted to achieve slow and mild acupuncture sensation; in addition, the facial muscles are pulled up with mechanics action. The intensive stimulation with electroacupuncture is recommended at Qianzheng (Extra), Yifeng (TE 17) and Yangbai (GB 14), which is given two or three treatments per week.

  8. [Theory analysis and clinical application of spirit-regulating and pain-relieving acupuncture method]. (United States)

    Chen, Liang; Tang, Lewei; Du, Huaibin; Zheng, Hui; Liang, Fanrong


    The theoretical foundation and scientific connotation of spirit-regulating and pain-relieving acupuncture method as well as its clinical application for pain are discussed. During spirit regulation, attention should be paid on regulating heart and brain, while acupoints should be selected mainly from the Heart Meridian, Pericardium Meridian and Governor Vessel. It has significant efficacy for refractory pain in clinical treatment. Spirit-regulating and pain-relieving acupuncture method is development of acupuncture treating spirit, and it is an important method for pain in clinic. Improvement on sensitization of pain center and brain function is considered as one of the mechanisms in spirit-regulating and pain-relieving acupuncture method.

  9. Geometrical theory to predict eccentric photorefraction intensity profiles in the human eye (United States)

    Roorda, Austin; Campbell, Melanie C. W.; Bobier, W. R.


    In eccentric photorefraction, light returning from the retina of the eye is photographed by a camera focused on the eye's pupil. We use a geometrical model of eccentric photorefraction to generate intensity profiles across the pupil image. The intensity profiles for three different monochromatic aberration functions induced in a single eye are predicted and show good agreement with the measured eccentric photorefraction intensity profiles. A directional reflection from the retina is incorporated into the calculation. Intensity profiles for symmetric and asymmetric aberrations are generated and measured. The latter profile shows a dependency on the source position and the meridian. The magnitude of the effect of thresholding on measured pattern extents is predicted. Monochromatic aberrations in human eyes will cause deviations in the eccentric photorefraction measurements from traditional crescents caused by defocus and may cause misdiagnoses of ametropia or anisometropia. Our results suggest that measuring refraction along the vertical meridian is preferred for screening studies with the eccentric photorefractor.

  10. On solution of Maxwell's equations in axisymmetric domains with edges. Part I: Theoretical aspects

    International Nuclear Information System (INIS)

    Nkemzi, Boniface


    In this paper we present the basic mathematical tools for treating boundary value problems for the Maxwell's equations in three-dimensional axisymmetric domains with reentrant edges by means of partial Fourier analysis. We consider the decomposition of the classical and regularized time-harmonic three-dimensional Maxwell's equations into variational equations in the plane meridian domain of the axisymmetric domain and define suitable weighted Sobolev spaces for their treatment. The trace properties of these spaces on the rotational axis and some properties of the solutions are proved, which are important for further numerical treatment, e.g. by the finite-element method. Particularly, a priori estimates of the solutions of the reduced system are given and the asymptotic behavior of these solutions near reentrant corners of the meridian domain is explicitly described by suitable singular functions.

  11. Determination of plasma parameters from soft X-ray images for coronal holes /open magnetic field configurations/ and coronal large-scale structures /extended closed-field configurations/ (United States)

    Maxson, C. W.; Vaiana, G. S.


    In connection with high-quality solar soft X-ray images the 'quiet' features of the inner corona have been separated into two sharply different components, including the strongly reduced emission areas or coronal holes (CH) and the extended regions of looplike emission features or large-scale structures (LSS). Particular central meridian passage observations of the prominent CH1 on August 21, 1973, are selected for a quantitative study. Histogram photographic density distributions for full-disk images at other central meridian passages of CH 1 are also presented, and the techniques of converting low photographic density data to deposited energy are discussed, with particular emphasis on the problems associated with the CH data.

    @@ Background: Dysphagia caused by stroke is common, but there is still no good therapy. After stroke, cerebral function is damaged severely, control function of V, VII, IX, X cranial nerve are disorder, swallow muscles can't complete swallow coordinately. Traditional Chinese medicine consider yin yang were damaged, damage of yang influence impel function of viscera and transmission function of meridian and collateral, damage of yin lead to blockage of meridian and collateral and qi blood, then dysphagia. Traditional Chinese medicine ion introduction and intermediate ultrasound combined with acupoint therapy is a kind method to treat dysphagia after stroke. It makes use of traditional Chinese medical theory and modern technique and gains good effect.

  13. On the association of magnetic clouds with disappearing filaments

    International Nuclear Information System (INIS)

    Wilson, R.M.; Hildner, E.


    We present evidence that an interplanetary magnetic cloud preceding an interaction region, observed at earth January 24, 1974, is associated with the eruptive filament or disparition brusque (DB) near central meridian on January 18. The DB also was associated with a long-decay soft X ray transient (LDE) and a long-duration gradual-rise-and-fall (GRF) radio burst. To assess whether magnetic clouds are generally associated with DBs, we present results from statistical testing of the relation of 33 magnetic clouds (and 33 control samples without magnetic clouds) to disappearing filaments near central meridian (approx. 99% confidence. There is a suggestion that clouds following shocks, probably launched at times of solar flares, are not as strongly associated with disappearing filaments as are clouds launched less violently

  14. Acupuncture's Cardiovascular Actions: A Mechanistic Perspective


    Longhurst, John


    Over the last several decades, there has been an explosion of articles on acupuncture, including studies that have begun to explore mechanisms underlying its analgesic and cardiovascular actions. Modulation of cardiovascular function is most effective during manual and low-frequency, low-intensity electroacupuncture (EA) at a select set of acupoints situated along meridians located over deep somatic nerves on the upper and lower extremities. Stimulation at these acupoints activates underlying...

    Monzon, J. J.; Barriuso, A. G.; Sanchez-Soto, L. L. [Departamento de Optica, Facultad de Fisica, Universidad Complutense, E-28040 Madrid (Spain); Montesinos-Amilibia, J. M. [Departamento de Geometria y Topologia, Facultad de Matematicas, Universidad Complutense, E-28040 Madrid (Spain)


    We reinterpret the transfer matrix for an absorbing system in very simple geometrical terms. In appropriate variables, the system appears as performing a Lorentz transformation in a (1 + 3)-dimensional space. Using homogeneous coordinates, we map that action on the unit sphere, which is at the realm of the Klein model of hyperbolic geometry. The effects of absorption appear then as a loxodromic transformation, that is, a rhumb line crossing all the meridians at the same angle.

    Objective: To characterize the cortical activation of acupuncture with BOLD-based fMRI technique. Methods: The study was performed in 31 healthy volunteers (27 men, 4 women; age range 21-48 years) with acupuncture of points along the stomach meridian of Foot-Yangming and the gallbladder meridian of Foot-Shaoyang. The acupoints of the stomach meridian of Foot-Yangming included Futu (S 32) in 7 volunteers and Zusanli (S 36) in 9 volunteers; and the acupoints of the gallbladder meridian of Foot-Shaoyang included Yanglingquan (G34) in 7 volunteers and Guangming (G37) in 8 volunteers. MRI data were acquired on a GE 1.5 T Signa Horizon/Echo-speed scanner. 12 oblique axial slices paralleled to the AC-PC line were scanned. T 2 * images were acquired using EPI technique. Data sets of sequential images were analyzed with software package AFNI. Results: Acupuncture at points S32 and S36 resulted in activation of the hypothalamus, nucleus accumbens, hippocampal complex, and frontal gyri, and the average enhancement in the above activated areas was (4.28 ± 1.50)%. Acupuncture at vision-related points G34 and G37 resulted in activation of the occipital lobe as well as other cortices such as pons, basal ganglion, temporal lobe, and frontal lobe, and the BOLD signal changes of the visual cortex were (3.31 ± l.2)%. Conclusion: These preliminary fMRI results demonstrate strong regional BOLD signal changes in the brain upon acupuncture, hence demonstrates physiological evidence of acupuncture effect. (authors)

  2. Peripheral refraction in normal infant rhesus monkeys (United States)

    Hung, Li-Fang; Ramamirtham, Ramkumar; Huang, Juan; Qiao-Grider, Ying; Smith, Earl L.


    Purpose To characterize peripheral refractions in infant monkeys. Methods Cross-sectional data for horizontal refractions were obtained from 58 normal rhesus monkeys at 3 weeks of age. Longitudinal data were obtained for both the vertical and horizontal meridians from 17 monkeys. Refractive errors were measured by retinoscopy along the pupillary axis and at eccentricities of 15, 30, and 45 degrees. Axial dimensions and corneal power were measured by ultrasonography and keratometry, respectively. Results In infant monkeys, the degree of radial astigmatism increased symmetrically with eccentricity in all meridians. There were, however, initial nasal-temporal and superior-inferior asymmetries in the spherical-equivalent refractive errors. Specifically, the refractions in the temporal and superior fields were similar to the central ametropia, but the refractions in the nasal and inferior fields were more myopic than the central ametropia and the relative nasal field myopia increased with the degree of central hyperopia. With age, the degree of radial astigmatism decreased in all meridians and the refractions became more symmetrical along both the horizontal and vertical meridians; small degrees of relative myopia were evident in all fields. Conclusions As in adult humans, refractive error varied as a function of eccentricity in infant monkeys and the pattern of peripheral refraction varied with the central refractive error. With age, emmetropization occurred for both central and peripheral refractive errors resulting in similar refractions across the central 45 degrees of the visual field, which may reflect the actions of vision-dependent, growth-control mechanisms operating over a wide area of the posterior globe.

    Bright electron aurorae almost always followed by red lower edge occur when the Earth is being passed by high-velocity flows from coronal holes within the auroral range at the night meridian. In contrast to other types of the solar wind the high-velocity flows from coronal holes do not cause the occurrence of A type red polar aurorae, that is, the spectrum of electrons pouring into the Earth atmosphere in these cases is shifted towards higher energies

    Whether subgroups of functional dyspepsia (FD) should be treated with different approaches is controversially discussed in research. As our previous study has demonstrated the effect of acupuncture in FD treatment, we now further analyze the therapeutic effect of acupuncture in the treatment of postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). A retrospective analysis was conducted in 465 eligible PDS patients and 241 EPS patients. 4 acupuncture groups (group A: specific acupoints along the stomach meridian; group B: non-specific acupoints along the stomach meridian; group C: alarm and transport acupoints; group D: specific acupoints along the gallbladder meridian) were compared with a non-acupoint sham acupuncture group and an itopride group. The patients were treated in 5 consecutive sessions per week for 4 weeks and were followed-up for 12 weeks afterwards. Primary outcome of the study was defined as response rate and symptom improvement as measured by the Symptom Index of Dyspepsia, while secondary outcome was designated as improvement in quality of life (QoL) as determined by the Nepean Dyspepsia Index. Symptoms of dyspepsia and QoL were improved from baseline in all groups. In EPS patients, no statistically significant differences could be observed in response rate (p = 0.239) and symptoms improvement (p = 0.344 for epigastric pain; p = 0.465 for epigastric burning). In contrast, PDS patients of the acupuncture group A showed higher response rate (53.2% vs. 19.7%, pitopride group. FD patients with PDS responded better to the acupuncture therapies, especially at the specific acupoints along the stomach meridian. The positive therapeutic effect of acupuncture on PDS was correlated with the improvement in postprandial fullness. NCT00599677. © 2015 S. Karger GmbH, Freiburg.

  19. [Characteristics of acupuncture textbooks on editing mode and content in the Republic of China]. (United States)

    Zhao, Jing; Zhang, Shujian


    Sixty-seven textbooks in the Republic of China have been collected and divided into three stages according to their editing modes, named the early stage (1912-1927), the middle stage (1928-1939) and the late stage (1940-1949). The traditional teaching material of acupuncture was predominated at the early stage in the textbook compilation; meanwhile the editing mode was simple, and the content of it focuses on meridians, collaterals and acupoints and the modern scientific theories have been preliminarily introduced. The textbooks at the middle stage were edited as two modes, "western medicine+acupuncture" and "general introduction→meridian points→manipulation (techniques of acupuncture and moxibustion)→treatment". The knowledge in anatomy, physiology and pathology of western medicine has been involved in content, giving the great consideration to the clinical practicability. However, a part of textbooks still followed the traditional theory of acupuncture at the middle stage. At the late stage, the textbooks were edited align with "acupuncture science, moxibustion science, meridian point science and treatment science"; or in supplementation of the "diagnosis" on the base of "general introduction→ meridian points→techniques of acupuncture→treatment", or edited as "general introduction→points→treatment". The compilation of the textbooks at this stage not only followed but also improved the integration of western and Chinese medicine as that at the middle stage, which turned to be more scientific. Additionally, in the teaching content, the acupoint was much more considerable as compared with pulse and the section of diagnosis has been involved. As a result, a framework of acupuncture discipline has been established preliminarily by taking acupuncture technique, moxibustion technique, acupoints and treatment as the core. The development of the editing mode and content of textbooks played a great impact on the unified compilation of the acupuncture

  3. Induction of Hyperalgesia in Pigs through Blocking Low Hydraulic Resistance Channels and Reduction of the Resistance through Acupuncture: A Mechanism of Action of Acupuncture

    Directory of Open Access Journals (Sweden)

    Wei-Bo Zhang


    Full Text Available According to the classic theory of Chinese medicine, pain is due to the blockage in meridian channels, and acupuncture was invented to treat pain by “dredging” the channels. To test the theory, a hyperalgesia model was made by injecting hydrogel into low hydraulic resistance channel (LHRC in 12 anaesthetized minipigs. Tail-flick threshold and ear-flick threshold were measured using a thermal radiation dolorimeter, and relative flick threshold (RFT was calculated. Hydraulic resistance (HR was measured with a biological HR measuring instrument on low HR points on LHRC and on control points with higher HR located outside LHRC; readings were recorded before, during, and after acupuncture treatment. RFT decreased after blocking the LRHC and was still significantly decreased 2 days and 4 days afterwards. No significant changes occurred when injecting saline into the same points or injecting gel into points outside the channel. Subsequent acupuncture reduced HR on LRHC along meridians but had no significant effect on sites with higher HR located outside LHRC. One of the mechanisms of action of acupuncture treatment for chronic pain may be that acupuncture affects peripheral tissue by reducing the HR in LHRC along meridians, improving the flow of interstitial fluid and removing algogenic substances and thereby relieving pain.

  4. Diagnosis of Clostridium difficile-associated disease: examination of multiple algorithms using toxin EIA, glutamate dehydrogenase EIA and loop-mediated isothermal amplification. (United States)

    Bamber, A I; Fitzsimmons, K; Cunniffe, J G; Beasor, C C; Mackintosh, C A; Hobbs, G


    The laboratory diagnosis of Clostridium difficile infection (CDI) needs to be accurate and timely to ensure optimal patient management, infection control and reliable surveillance. Three methods are evaluated using 810 consecutive stool samples against toxigenic culture: CDT TOX A/B Premier enzyme immunoassay (EIA) kit (Meridian Bioscience, Europe), Premier EIA for C. difficile glutamate dehydrogenase (GDH) (Meridian Bioscience, Europe) and the Illumigene kit (Meridian Bioscience, Europe), both individually and within combined testing algorithms. The study revealed that the CDT TOX A/B Premier EIA gave rise to false-positive and false-negative results and demonstrated poor sensitivity (56.47%), compared to Premier EIA for C. difficile GDH (97.65%), suggesting this GDH EIA can be a useful negative screening method. Results for the Illumigene assay alone showed sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) of 91.57%, 98.07%, 99.03% and 84.44%, respectively. A two-stage algorithm using Premier EIA for C. difficile GDH/Illumigene assay yielded superior results compared with other testing algorithms (91.57%, 98.07%, 99.03% and 84.44%, respectively), mirroring the Illumigene performance. However, Illumigene is approximately half the cost of current polymerase chain reaction (PCR) methods, has a rapid turnaround time and requires no specialised skill base, making it an attractive alternative to assays such as the Xpert C. difficile assay (Cepheid, Sunnyvale, CA). A three-stage algorithm offered no improvement and would hamper workflow.

  5. Optimal viewing position in vertically and horizontally presented Japanese words. (United States)

    Kajii, N; Osaka, N


    In the present study, the optimal viewing position (OVP) phenomenon in Japanese Hiragana was investigated, with special reference to a comparison between the vertical and the horizontal meridians in the visual field. In the first experiment, word recognition scores were determined while the eyes were fixating predetermined locations in vertically and horizontally displayed words. Similar to what has been reported for Roman scripts, OVP curves, which were asymmetric with respect to the beginning of words, were observed in both conditions. However, this asymmetry was less pronounced for vertically than for horizontally displayed words. In the second experiment, the visibility of individual characters within strings was examined for the vertical and horizontal meridians. As for Roman characters, letter identification scores were better in the right than in the left visual field. However, identification scores did not differ between the upper and the lower sides of fixation along the vertical meridian. The results showed that the model proposed by Nazir, O'Regan, and Jacobs (1991) cannot entirely account for the OVP phenomenon. A model in which visual and lexical factors are combined is proposed instead.

    To compare the difference in the efficacy on gait time cycle of ischemic stroke between yin-yang respiratory reinforcing and reducing needling technique (yin-yang needling) and the conventional acupuncture. Sixty cases of ischemic stroke were randomized into a conventional acupuncture group and a yin-yang needling group, 30 cases in each one. The basic treatment (the control of blood pressure, blood sugar and blood lipid, the intravenous drops of ginkgo leaf extract and dipyridamole injection and vinpocetine injection) were applied in the two groups. Additionally, in the conventional acupuncture group, the acupoints of the Stomach Meridian of Foot-Yangming [Biguan (ST 31), Liangqiu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), etc.] were selected and stimulated with the even needling technique. In the yin-yang needling group, the acupoints of yin meridians such as Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9) and Sanyinjiao (SP 6), etc. and the acupoints of yang meridians such as Biguan (ST 31), Liangqiu (ST 34) and Yanglingquan (GB 34), etc. were selected. The reducing manipulation of respiratory reinforcing and reducing technique was applied to the acupoints of yin meridians and the reinforcing manipulation was applied to the acupoints of yang meridians. The kinematics time parameters were determined and compared before and 4 weeks after treatment. After treatment, the differences in the gait cycle, the phase time of standing (%), the phase time of single support (%), the phase time of unilateral sway (%) on the affected (healthy) foot and phase time of double support (%) were significant as compared with those before treatment in the patients of the two groups (all P yin-yang needling group were improved much obviously after treatment as compared with those in the conventional acupuncture group. The differences in support phase time (%), single support phase time (%) and sway phase time (%) were significant between the affected limb and

    Full Text Available Abstract Background Whether acupuncture is effective for patients with functional constipation is still unclear. Therefore, we report the protocol of a randomized controlled trial of using acupuncture to treat functional constipation. Design A randomized, controlled, four-arm design, large-scale trial is currently undergoing in China. Seven hundred participants are randomly assigned to three acupuncture treatment groups and Mosapride Citrate control group in a 1:1:1:1 ratio. Participants in acupuncture groups receive 16 sessions of acupuncture treatment, and are followed up for a period of 9 weeks after randomization. The acupuncture groups are: (1 Back-Shu and Front-Mu acupoints of Large Intestine meridians (Shu-Mu points group; (2 He-Sea and Lower He-Sea acupoints of Large Intestine meridians (He points group; (3 Combining used Back-Shu, Front-Mu, He-Sea, and Lower He-Sea acupoints of Large Intestine meridians (Shu-Mu-He points group. The control group is Mosapride Citrate group. The primary outcome is frequency of defecation per week at the fourth week after randomization. The secondary outcomes include Bristol stool scale, the extent of difficulty during defecating, MOS 36-item Short Form health survey (SF-36, Self-Rating Anxiety Scale (SAS, and Self-rating Depression Scale (SDS. The first two of second outcomes are measured 1 week before randomization and 2, 4, and 8 weeks after randomization. Other second outcomes are measured 1 week before randomization and 2 and 4 weeks after randomization, but SF-36 is measured at randomization and 4 weeks after randomization. Discussion The result of this trial (which will be available in 2012 will confirm whether acupuncture is effective to treat functional constipation and whether traditional acupuncture theories play an important role in it.

  8. [Needling technique of Professor Li Yan-Fang]. (United States)

    Li, Li-Jun


    Experiences of needling techniques of Professor LI Ya- fang is introduced in this article. Gentle and superficial insertion is adopted by Professor LI in clinic. Emphases are put on the qi regulation function, needling sensation to the affected region and insertion with both hands, especially the function of the left hand as pressing hand. The gentle and superficial insertion should be done as the follows: hold the needle with the right hand, press gently along the running course of meridians with the left hand to promote qi circulation, hard pressing should be applied at acupoints to disperse the local qi and blood, insert the needle gently and quickly into the subcutaneous region with the right hand, and stop the insertion when patient has the needling sensation. While the fast needling is characterized with shallow insertion and swift manipulation: the left hand of the manipulator should press first along the running course of the meridian, and fix the local skin, hold the needle with the right hand and insert the needle quickly into the acupoint. Withdrawal of the needle should be done immediately after the reinforcing and reducing manipulations. Professor LI is accomplished in qi regulation. It is held by him that regulating qi circulation is essence of acupuncture, letting the patient get the needling sensation is the most important task of needling. Lifting, thrusting and rotation manipulations should be applied to do reinforcing or reducing. The tissue around the tip of the needle should not be too contracted or too relaxed, and the resistance should not be too strong or too weak. The feeling of the insertion hand of the practitioner should not be too smooth or too hesitant. Needle should be inserted into the skin quickly at the moment of hard pressing by the left hand. And then, slow rotation and gentle lifting and thrusting can be applied to promote the needling sensation like electric current pass through and to reach the affected region along the

  9. New true-triaxial rock strength criteria considering intrinsic material characteristics (United States)

    Zhang, Qiang; Li, Cheng; Quan, Xiaowei; Wang, Yanning; Yu, Liyuan; Jiang, Binsong


    A reasonable strength criterion should reflect the hydrostatic pressure effect, minimum principal stress effect, and intermediate principal stress effect. The former two effects can be described by the meridian curves, and the last one mainly depends on the Lode angle dependence function. Among three conventional strength criteria, i.e. Mohr-Coulomb (MC), Hoek-Brown (HB), and Exponent (EP) criteria, the difference between generalized compression and extension strength of EP criterion experience a firstly increase then decrease process, and tends to be zero when hydrostatic pressure is big enough. This is in accordance with intrinsic rock strength characterization. Moreover, the critical hydrostatic pressure I_c corresponding to the maximum difference of between generalized compression and extension strength can be easily adjusted by minimum principal stress influence parameter K. So, the exponent function is a more reasonable meridian curves, which well reflects the hydrostatic pressure effect and is employed to describe the generalized compression and extension strength. Meanwhile, three Lode angle dependence functions of L_{{MN}}, L_{{WW}}, and L_{{YMH}}, which unconditionally satisfy the convexity and differential requirements, are employed to represent the intermediate principal stress effect. Realizing the actual strength surface should be located between the generalized compression and extension surface, new true-triaxial criteria are proposed by combining the two states of EP criterion by Lode angle dependence function with a same lode angle. The proposed new true-triaxial criteria have the same strength parameters as EP criterion. Finally, 14 groups of triaxial test data are employed to validate the proposed criteria. The results show that the three new true-triaxial exponent criteria, especially the Exponent Willam-Warnke criterion (EPWW) criterion, give much lower misfits, which illustrates that the EP criterion and L_{{WW}} have more reasonable meridian

    Kyoung Min Lee

    Full Text Available To determine using swept-source optical coherence tomography (SS-OCT whether there are differences in the location of the anterior lamina cribrosa insertion (ALI in primary open-angle glaucoma (POAG patients and healthy subjects.Fifty three eyes from 53 patients with POAG, and 53 eyes from 53 age-matched healthy subjects were included prospectively in Seoul National University Bundang Hospital. Twelve radial line B-scans centered on the optic disc in every half-clock-hour meridian were acquired using SS-OCT. The ALI position was assessed by measuring two parameters: (1 ALI distance (ALID--the distance from the anterior scleral canal opening (ASCO to the ALI; and (2 marginal anterior lamina cribrosa surface depth (mALCSD--the perpendicular distance from the ASCO plane to the anterior lamina cribrosa surface. These parameters were compared between the two groups for each meridian.Both ALID (256 ± 54 vs. 209 ± 37 µm, mean ± SD, p < 0.001 and mALCSD (232 ± 63 vs. 187 ± 40 µm, p < 0.001 were significantly greater in the POAG group than in the normal group. The largest difference was observed at the 6.5 o'clock and 11.5 o'clock meridians for both ALID and mALCSD. Multiple regression analysis revealed a negative correlation between age and both ALID and mALCSD in the control group, and a negative correlation between mean deviation of the visual field test and both ALID and mALCSD in the POAG group.The ALI was displaced posteriorly in eyes with POAG compared to those of healthy controls. This finding suggests that the posteriorly located lamina cribrosa insertion is an important component of glaucomatous optic nerve excavation.

  11. Motion of charged particles in the magnetosphere

    International Nuclear Information System (INIS)

    Mukherjee, G.K.; Rajaram, R.


    The adiabatic motion of charged particles in the magnetosphere has been investigated using Mead-Fairfield magnetospheric field model (Mead and Fairfield, 1975). Since the motion of charged particles in a dipolar field geometry is well understood, we bring out in this paper some important features in characteristic motion due to non-dipolar distortions in the field geometry. We look at the tilt averaged picture of the field configuration and estimate theoretically the parameters like bounce period, longitudinal invariant and the bounce averaged drift velocities of the charged particle in the Mead-Fairfield field geometry. These parameters are evaluated as a function of pitch angle and azimuthal position in the region of ring current (5 to 7 Earth radii from the centre of the Earth) for four ranges of magnetic activity. At different longitudes the non-dipolar contribution as a percentage of dipole value in bounce period and longitudinal invariant shows maximum variation for particles close to 90 0 pitch angles. For any low pitch angle, these effects maximize at the midnight meridian. The radial component of the bounce averaged drift velocity is found to be greatest at the dawn-dusk meridians and the contribution vanishes at the day and midnight meridians for all pitch angles. In the absence of tilt-dependent terms in the model, the latitudinal component of the drift velocity vanishes. On the other hand, the relative non-dipolar contribution to bounce averaged azimuthal drift velocity is very high as compared to similar contribution in other characteristic parameters of particle motion. It is also shown that non-dipolar contribution in bounce period, longitudinal invariant and bounce averaged drift velocities increases in magnitude with increase in distance and magnetic activity.

    Full Text Available The purpose of this study was to describe the ocular refractive state (ORS of fighting bulls. The study consisted of 90 ophthalmological healthy animals (85 in post-mortem and 5 in living conditions, resp.. The ORS of the eyes (2 per animal was determined using streak retinoscopy. In vivo animals were assessed at a fighting bull farm facility. Post-mortem measurements were carried out at a local arena. The ORS along the horizontal meridian ranged between −1.00 and +2.50 diopters (D, with a mean of +0.66±0.85 D in post-mortem animals. Values for in vivo conditions were similar (+0.75±0.46 D. Left and right eyes were highly correlated in both sets (p<0.001. A fairly good correlation was also observed when comparing living and post-mortem eyes in the same animals. Anisometropia ≥ 1.00 D was diagnosed in 3 animals. Astigmatism (≥+0.5 D was detected in 93% of the eyes. To our knowledge, the ORS of the fighting bull has been reported for the first time. Although values vary among individuals, all eyes presented a marked astigmatism. Whereas the horizontal meridian was slightly hyperopic, the vertical meridian was always closer to emmetropia. These results represent a starting point to understand the ocular optics of this kind of animals, which might benefit the selection of animals at the farm before being sent to the bullfighting arena.

  13. A test of the stability of Cd, Cu, Hg, Pb and Zn profiles over two decades in lake sediments near the Flin Flon Smelter, Manitoba, Canada

    Energy Technology Data Exchange (ETDEWEB)

    Percival, J.B.; Outridge, P.M., E-mail:


    Lake sediments are valuable archives of atmospheric metal deposition, but the stability of some element profiles may possibly be affected by diagenetic changes over time. In this extensive case study, the stability of sedimentary Cd, Cu, Hg, Pb and Zn profiles was assessed in dated sediment cores that were collected in 2004 from four smelter-affected lakes near Flin Flon, Manitoba, which had previously been cored in 1985. Metal profiles determined in 1985 were in most cases clearly reproduced in the corresponding sediment layers in 2004, although small-scale spatial heterogeneity in metal distribution complicated the temporal comparisons. Pre-smelter (i.e. pre-1930) increases in metal profiles were likely the result of long-range atmospheric metal pollution, coupled with particle mixing at the 1930s sediment surface. However, the close agreement between key inflection points in the metal profiles sampled two decades apart suggests that metals in most of the lakes, and Hg and Zn in the most contaminated lake (Meridian), were stable once the sediments were buried below the surface mixed layer. Cadmium, Cu and Pb profiles in Meridian Lake did not agree as well between studies, showing evidence of upward remobilization over time. Profiles of redox-indicator elements (Fe, Mn, Mo and U) suggested that the rate of Mn oxyhydroxide recycling within sediment was more rapid in Meridian Lake, which may have caused the Cd, Cu and Pb redistribution. - Highlights: • Sedimentary Cd, Cu, Hg, Pb and Zn profiles in four lakes were mostly unchanged over 19 years. • In one lake, Cd, Cu and Pb profiles were offset relative to the originals. • The offset could indicate diagenetic upcore dispersal of these metals.

    We used synchrotron x-ray fluorescence analysis to probe the distribution of four chemical elements in and around acupuncture points, two located in the forearm and two in the lower leg. Three of the four acupuncture points showed significantly elevated concentrations of elements Ca, Fe, Cu and Zn in relation to levels in the surrounding tissue, with similar elevation ratios for Cu and Fe. The mapped distribution of these elements implies that each acupuncture point seems to be elliptical with the long axis along the meridian.

  18. Tropospheric haze and colors of the clear daytime sky. (United States)

    Lee, Raymond L


    To casual observers, haze's visible effects on clear daytime skies may seem mundane: significant scattering by tropospheric aerosols visibly (1) reduces the luminance contrast of distant objects and (2) desaturates sky blueness. However, few published measurements of hazy-sky spectra and chromaticities exist to compare with these naked-eye observations. Hyperspectral imaging along sky meridians of clear and hazy skies at one inland and two coastal sites shows that they have characteristic colorimetric signatures of scattering and absorption by haze aerosols. In addition, a simple spectral transfer function and a second-order scattering model of skylight reveal the net spectral and colorimetric effects of haze.

  20. "Oh Such a Good Sound": A Case for a Macrocosmic Aesthetic of Grace in ASMR


    Philip Rice


    Autonomous Sensory Meridian Response (ASMR) is a pseudoscientific neologism for a pleasurable tingling sensation reported by a growing number of people in response to soft sounds such as whispers, crinkles, and taps. ASMR is described as a “headgasm” where tingles start in the scalp or neck and radiate throughout the body. An active community of enthusiasts has emerged on YouTube in support of videos crafted by “ASMRtists.” Characteristics of the videos include a strong sense of personal...

  1. Numerical Model of High Strength Concrete (United States)

    Wang, R. Z.; Wang, C. Y.; Lin, Y. L.


    The purpose of this paper is to present a three-dimensional constitutive model based on the concept of equivalent uniaxial strain. closed Menetrey-Willam (CMW) failure surfaces which combined with Menetrey-Willam meridian and the cap model are introduced in this paper. Saenz stress-strain model is applied and adjusted by the ultimate strength parameters from CMW failure surface to reflect the latest stress or strain condition. The high strength concrete (HSC) under tri-axial non-proportional loading is considered and the model in this paper performed a good prediction.

  2. Airborne gamma-ray spectrometer and magnetometer survey: north/south tieline. Final report

    International Nuclear Information System (INIS)


    An airborne high sensitivity gamma-ray spectrometer and magnetometer survey was conducted along the 99 0 longitude meridian from the Canadian border southward to the Mexican border. A total of 1555 line miles of geophysical data were acquired and, subsequently, compiled. The north-south tieline was flown as part of the National Uranium Resources Evaluation. NURE is a program of the US Department of Energy's Grand Junction, Colorado, office to acquire and compile geologic and other information with which to assess the magnitude and distribution of uranium resources and to determine areas favorable for the occurrence of uranium in the United States

    Carballo, O.; Sbrocco; J; Calmels, A.; Sotorres, E.; Miglianelli, C.


    This present work aims to provide a territorial ordering in an area limited by the 36 grades 39 minutes and 36 grades 43 minutes Southern Parallels and the 64 grades 20 minutes and 64 grades 27 minutes. Meridians from the same hemisphere; within such area, the population from Toay and surroundings are held/contained. The empiric method employed was taken from Gomez Orea (1993). The area was divided into environmental synthesis units and through the use of different proposed tasks it was possible to reach an objective description of the area with the distribution of its varied units [es

  4. astroplan: Observation planning package for astronomers (United States)

    Morris, Brett M.; Tollerud, Erik; Sipocz, Brigitta; Deil, Christoph; Douglas, Stephanie T.; Berlanga Medina, Jazmin; Vyhmeister, Karl; Price-Whelan, Adrian M.; Jeschke, Eric


    astroplan is a flexible toolbox for observation planning and scheduling. It is powered by Astropy (ascl:1304.002); it works for Python beginners and new observers, and is powerful enough for observatories preparing nightly and long-term schedules as well. It calculates rise/set/meridian transit times, alt/az positions for targets at observatories anywhere on Earth, and offers built-in plotting convenience functions for standard observation planning plots (airmass, parallactic angle, sky maps). It can also determine the observability of sets of targets given an arbitrary set of constraints (i.e., altitude, airmass, moon separation/illumination, etc.).

  5. Beam structure of Jupiter's decametric radiation

    Maeda, K; Carr, T D


    The well-defined zones of central meridian longitude within which the probability of jovian radio emission at frequencies near 22 MHz is relatively high are known as sources A, B and C. Each consists of a component for which the emission probability is strongly correlated with Io's orbital position, and another that is Io-unrelated. The paper presents convincing evidence based on concurrent observations from two Voyager spacecraft and a terrestrial observatory that the component of source A radiation that is not correlated with Io's position is generally emitted in co-rotating searchlight beams of distinctive cross-sectional shape.

    With NCEP/NCAR reanalysis daily data and SST for 1998, the paper investigates the features of summer monsoon low-frequency oscillation (LFO) over the South China Sea (SCS). Results show that SCS summer monsoon onset is enhanced because of its LFO. Low-frequency (LF) low-level convergence (divergence) region of SCS is in the LF positive (negative) rainfall area. LFO of the SCS region migrates from south to north in the meridian and from west to east in zonal direction. LF divergence of SCS is vertically compensating to each other between high and low level.

  7. Verbal Dreamscapes. Dorothea Tanning’s Visual Literature

    Directory of Open Access Journals (Sweden)

    Glăvan Gabriela


    Full Text Available A Surrealist painter whose artistic vision is equally visible in her literary works, Dorothea Tanning established a solid dialogue between literature and the plastic arts. The corpus of her literary oeuvre is rather small, consisting of a novel, a volume of poetry and her memoir, Between Lives. This paper argues that Tanning can be regarded as an exemplary author of a creative transfer between verbal and plastic imagination. It also explores the tension between the two means of expression, most visible in her novel Chasm: A Weekend. Here, the imagery and enigmatic symbolism of her painting come to life in the story of a strange little girl called Destina Meridian.

  8. Design of a rotational three-dimensional nonimaging device by a compensated two-dimensional design process. (United States)

    Yang, Yi; Qian, Ke-Yuan; Luo, Yi


    A compensation process has been developed to design rotational three-dimensional (3D) nonimaging devices. By compensating the desired light distribution during a two-dimensional (2D) design process for an extended Lambertian source using a compensation coefficient, the meridian plane of a 3D device with good performance can be obtained. This method is suitable in many cases with fast calculation speed. Solutions to two kinds of optical design problems have been proposed, and the limitation of this compensated 2D design method is discussed.

    Full Text Available The advent of molecular genetic comprises a true revolution of far-reaching consequences for human-kind, which evolved into a specialized branch of the modern-day Biochemistry. The analysis of specicgenomic information are gaining wide-ranging interest because of their signicance to the early diag-nosis of disease, and the discovery of modern drugs. In order to take advantage of a wide assortmentof signal processing (SP algorithms, the primary step of modern genomic SP involves convertingsymbolic-DNA sequences into complex-valued signals. How to represent the genetic code? Despitebeing extensively known, the DNA mapping into proteins is one of the relevant discoveries of genetics.The genetic code (GC is revisited in this work, addressing other descriptions for it, which can beworthy for genomic SP. Three original representations are discussed. The inner-to-outer map buildson the unbalanced role of nucleotides of a codon. A two-dimensional-Gray genetic representationis oered as a structured map that can help interpreting DNA spectrograms or scalograms. Theseare among the powerful visual tools for genome analysis, which depends on the choice of the geneticmapping. Finally, the world-chart for the GC is investigated. Evoking the cyclic structure of thegenetic mapping, it can be folded joining the left-right borders, and the top-bottom frontiers. As aresult, the GC can be drawn on the surface of a sphere resembling a world-map. Eight parallels oflatitude are required (four in each hemisphere as well as four meridians of longitude associated tofour corresponding anti-meridians. The tropic circles have 11.25o, 33.75o, 56.25o, and 78.5o (Northand South. Starting from an arbitrary Greenwich meridian, the meridians of longitude can be plottedat 22.5o, 67.5o, 112.5o, and 157.5o (East and West. Each triplet is assigned to a single point on thesurface that we named Nirenberg-Kohamas Earth. Despite being valuable, usual representations forthe GC can be

    Based on a combined structural, petrographic, and geochemical analysis, a new interpretation of the basic magmatism of Sidi Said Maachou (coastal Meseta) in two stages of emplacement is proposed. The first stage is characterized by transitional pyroclastic flows that have accompanied the opening of the West-Mesetian basin, during the Cambrian; the second stage is made of dykes of basalts, dolerites, and tephrites bearing nepheline. The emplacement of this undersaturated alkaline magma is associated to a sinistral sub meridian shear zone which has been activated at the end of the Caledonian orogenesis, by a mantellic advection.

    Energy Technology Data Exchange (ETDEWEB)



    This report contains detailed summaries, with bibliographies, of past, present, and planned geothermal development in 71 selected countries and areas. The report gives a pretty good description of types of work that had been done in each country by the mid 1980s, but does not tell much about which geothermal-provider country did the work. There are maps for most of the countries. There are numbers for market factors, but not for estimated geothermal potential. The information in this document has been superceded by the country summaries in the World Geothermal Congress Transactions of 1995, 2000, and 2005.

    Radicella Andrea Chiaramonte


    Full Text Available After having described gear wheels with teeth having the two sides constituted by different involutes and their importance in engineering applications, we stress the need for an efficient procedure for the automatic mesh generation of innovative gear teeth. First, we describe the procedure for the subdivision of the tooth profile in the various possible cases, then we show the method for creating the subdivision mesh, defined by two series of curves called meridians and parallels. Finally, we describe how the above procedure for automatic mesh generation is able to solve specific cases that may arise when dealing with teeth having the two sides constituted by different involutes.

    Alekseev, V.N.; Ievenko, I.B.; Oshchepkov, S.M.; Ignat'ev, V.M.; Zhondorov, V.A.


    Stable auroral red arcs (SAR-arcs) were observed in Majmaga (Φ S ∼56.5deg) at the Yakutsk meridian in November-December, 1987 and February, 1988. The SAR-arcs were observed to the equator of diffuse glow, located at lower latitudes with respect to discrete auroral forms, obviously, in the external plasmospheric projection area. It is noted that they appear both in disturbed periods and in those with medium magnetic activity (K p =3). The SAR-arc height is ∼450km

  15. Comparing the Zeiss Callisto Eye and the Alcon Verion Image Guided System Toric Lens Alignment Technologies. (United States)

    Hura, Arjan S; Osher, Robert H


    To compare the alignment meridian generated by the Zeiss Callisto Eye (Carl Zeiss AG, Dublin, CA) and the Alcon Verion Image Guided System (Alcon Laboratories, Inc., Fort Worth, TX). In this retrospective comparative evaluation of technology, intraoperative images were captured at different steps in the same surgery, allowing the comparison of the guidance lines generated by the Verion system to the parallel guidance lines generated by the Callisto Eye system. Measurements of each hemi-meridian were quantified using Adobe Photoshop 2015 CC software (Adobe Systems, San Jose, CA). The numbers of degrees separating these alignment meridians were calculated, entered into a database, and analyzed. The authors found that of 98 captured images of 16 eyes, the two technologies were identical in 0 eyes (θ 1 = θ 2 = 0), similar by 3° in 52 (53%) captured images (θ 1 ≠ θ 2 ≠ 0), and different by at least 3° in 46 (47%) captured images (θ 1 ≠ θ 2 ≠ 0). The target meridians were superimposed, the target lines were minimally separated, and the target lines were dissimilar. It was noted that some intraoperative variation occurred from measurement to measurement. Within the small group of 16 cases of routine toric lens implantation in this study, the absolute average number of degrees of misalignment between the Verion and Callisto Eye systems was 3.355 for θ 1 and 3.838 for θ 2 . On average, the intraoperative variation termed "drift" was noted to be 3.963° for θ 1 , and 4.557° for θ 2 . The authors found that small deviations were frequent when comparing two sophisticated technologies. Although deviations greater than 3° occurred in less than 47% of captured images from 16 eyes, smaller but significant variations of less than 3° occurred in 53% of captured images from 16 eyes. It was rare to identify a large deviation. However, the authors identified "drift" in the same eye when measurements were taken at different times. The results indicate that the two

  16. Strain hardening of aluminium alloy 3004 in the deep drawing and ironing processes

    International Nuclear Information System (INIS)

    Courbon, J.; Duval, J.L.


    The evolution of material hardening resulting from the canmaking operations on aluminium beverage cans has been investigated. Tensile tests in cup walls revealed that deep drawing induced softening in the hoop direction and hardening in the meridian direction. This anisotropy is retained in the ironing operation. Changes in strain path on a heavily cold-rolled material probably cause such a complex behaviour. To determine hardening laws for deep drawing, simple shear tests were thus performed because of the strain path similarity. They allowed to determine hardening laws over larger strains than tension could reach and revealed a saturation of stress. Altogether they proved adapted to the understanding of deep drawing.

    Fritz, T.A.; Baker, D.N.; McPherron, R.L.; Lennartsson, W.


    The event of March 22, 1979 has been the object of a concentrated study effort as a part of the Coordinated Data Analysis Workshop activity designated CDAW-6. Energetic electron and magnetic field measurements from a set of four satellites aligned from 6.6 to 13 R/sub E/ at the 0200 LT meridian at the time of the magnetospheric substorm event of 1100 UT are presented. These data are used to show that a magnetic X-line formed spontaneously in the vicinity of 7 R/sub E/ in response to a steady build-up of magnetic stress in the geomagnetic tail

  18. Effect of the interplanetary magnetic field on the distribution of electric fields in the polar ionosphere (United States)

    Uvarov, V. M.; Barashkov, P. D.


    Heppner (1972), in an analysis of satellite data, observed 12 types of electric-field distributions in the polar ionosphere along the morning-evening meridian. In the present paper it is shown that these distribution types can be described by the analytical model of Uvarov and Barashkov (1984). In this model the excitation of the electric fields is investigated by solving the set of continuity equations for current in three regions (the north and south polar caps and a region outside the caps) with allowance for the magnetic conjugacy of the ionosphere in the two hemispheres.

  19. Equilibrium positions on stationary orbits and planetary principal inertia axis orientations for the Solar System (United States)

    Romero, Pilar; Barderas, Gonzalo; Mejuto, Javier


    We present a qualitative analysis in a phase space to determine the longitudinal equilibrium positions on the planetary stationary orbits by applying an analytical model that considers linear gravitational perturbations. We discuss how these longitudes are related with the orientation of the planetary principal inertia axes with respect to their Prime Meridians, and then we use this determination to derive their positions with respect to the International Celestial Reference Frame. Finally, a numerical analysis of the non-linear effects of the gravitational fields on the equilibrium point locations is developed and their correlation with gravity field anomalies shown.

    International Nuclear Information System (INIS)

    Kudryavtseva, E A; Fedoseev, D A


    We study natural mechanical systems describing the motion of a particle on a two-dimensional Riemannian manifold of revolution in the field of a central smooth potential. We obtain a classification of Riemannian manifolds of revolution and central potentials on them that have the strong Bertrand property: any nonsingular (that is, not contained in a meridian) orbit is closed. We also obtain a classification of manifolds of revolution and central potentials on them that have the 'stable' Bertrand property: every parallel is an 'almost stable' circular orbit, and any nonsingular bounded orbit is closed.

  1. Energies of precipitating electrons during pulsating aurora events derived from ionosonde observations

    International Nuclear Information System (INIS)

    MacDougall, J.W.; Hofstee, J.; Koehler, J.A.


    The time-history of particle energies and fluxes associated with pulsating auroras in the morning sector is derived from ionosonde measurements. All the pulsating auroras studied showed a similar history with the pulsations occurring during a time interval of the order of an hour during which the average auroral Maxwellian characteristic energy stays relatively constant but the energy flux decreases progressively during the event. A possible explanation for this behaviour in terms of an injection of particles into a magnetospheric 'bottle' near the midnight meridian and the progressive precipitation out of the bottle during the pulsating event is suggested.

  2. Peripheral refractive correction and automated perimetric profiles. (United States)

    Wild, J M; Wood, J M; Crews, S J


    The effect of peripheral refractive error correction on the automated perimetric sensitivity profile was investigated on a sample of 10 clinically normal, experienced observers. Peripheral refractive error was determined at eccentricities of 0 degree, 20 degrees and 40 degrees along the temporal meridian of the right eye using the Canon Autoref R-1, an infra-red automated refractor, under the parametric conditions of the Octopus automated perimeter. Perimetric sensitivity was then undertaken at these eccentricities (stimulus sizes 0 and III) with and without the appropriate peripheral refractive correction using the Octopus 201 automated perimeter. Within the measurement limits of the experimental procedures employed, perimetric sensitivity was not influenced by peripheral refractive correction.

    Directory of Open Access Journals (Sweden)

    Shah Parag


    Full Text Available Aggressive posterior retinopathy of prematurity (formerly known as fulminate/type II/rush disease occurs in zone 1 or posterior zone 2. Treatment involves extensive near confluent laser ablation of a large area of avascular retina. Anterior segment ischemia is a rare complication that can occur due to injury to the long posterior ciliary arteries in the horizontal meridians during aggressive posterior laser treatment. The outcome of this rare complication is very poor. This case describes a favorable outcome of intravitreal injection of bevacizumab (Avastin in a case of anterior segment ischemia.

  5. Polarization transition between sunlit and moonlit skies with possible implications for animal orientation and Viking navigation: anomalous celestial twilight polarization at partial moon. (United States)

    Barta, András; Farkas, Alexandra; Száz, Dénes; Egri, Ádám; Barta, Pál; Kovács, József; Csák, Balázs; Jankovics, István; Szabó, Gyula; Horváth, Gábor


    Using full-sky imaging polarimetry, we measured the celestial distribution of polarization during sunset and sunrise at partial (78% and 72%) and full (100%) moon in the red (650 nm), green (550 nm), and blue (450 nm) parts of the spectrum. We investigated the temporal change of the patterns of degree p and angle α of linear polarization of sunlit and moonlit skies at dusk and dawn. We describe here the position change of the neutral points of sky polarization, and present video clips about the celestial polarization transition at moonlit twilight. We found that at partial moon and at a medium latitude (47° 15.481' N) during this transition there is a relatively short (10-20 min) period when (i) the maximum of p of skylight decreases, and (ii) from the celestial α pattern neither the solar-antisolar nor the lunar-antilunar meridian can be unambiguously determined. These meridians can serve as reference directions of animal orientation and Viking navigation based on sky polarization. The possible influence of these atmospheric optical phenomena during the polarization transition between sunlit and moonlit skies on the orientation of polarization-sensitive crepuscular/nocturnal animals and the hypothesized navigation of sunstone-aided Viking seafarers is discussed.

  6. Sky-distribution of intensity of synchrotron radio emission of relativistic electrons trapped in Earth’s magnetic field

    Directory of Open Access Journals (Sweden)

    Klimenko V.V.


    Full Text Available This paper presents the calculations of synchrotron radio emission intensity from Van Allen belts with Gaussian space distribution of electron density across L-shells of a dipole magnetic field, and with Maxwell’s relativistic electron energy distribution. The results of these calculations come to a good agreement with measurements of the synchrotron emission intensity of the artificial radiation belt’s electrons during the Starfish nuclear test. We have obtained two-dimensional distributions of radio brightness in azimuth — zenith angle coordinates for an observer on Earth’s surface. The westside and eastside intensity maxima exceed several times the maximum level of emission in the meridian plane. We have also constructed two-dimensional distributions of the radio emission intensity in decibels related to the background galactic radio noise level. Isotropic fluxes of relativistic electrons (Е~1 MeV should be more than 107 cm–2s–1 for the synchrotron emission intensity in the meridian plane to exceed the cosmic noise level by 0.1 dB (riometer sensitivity threshold.

  7. Electroacupuncture Improved the Function of Myocardial Ischemia Involved in the Hippocampus-Paraventricular Nucleus-Sympathetic Nerve Pathway

    Directory of Open Access Journals (Sweden)

    Shuai Cui


    Full Text Available We investigated the hippocampus-paraventricular nucleus- (PVN- sympathetic nerve pathway in electroacupuncture (EA at the heart meridian for the treatment of myocardial ischemia by observing PVN neuronal discharge, sympathetic nerve discharge, and hemodynamics parameters. Sprague Dawley (SD rats were equally divided into four groups: Sham, Model, Model + EA, and Model + EA + Lesion. The model rat was established by ligating the left anterior descending branch of the coronary artery. Changes in the sympathetic nerve discharge and hemodynamic parameters were observed. The Model + EA exhibited a significantly lower discharge frequency of PVN neurons compared with the Model. The Model + EA + Lesion had a significantly higher discharge frequency compared with the Model + EA. The total discharge frequency of PVN neurons and interneurons were positively correlated with the sympathetic nerve discharge. The total discharge frequency of PVN neurons was positively correlated with heart rate (HR and negatively correlated with mean arterial pressure (MAP and rate pressure product (RPP. The discharge frequency of interneurons was positively correlated with HR and negatively correlated with MAP and RPP. The hippocampus-PVN-sympathetic nerve pathway is involved in electroacupuncture at the heart meridian and interneurons are the key neurons in PVNs.

  8. [Exploration of acupoint combination and needling techniques in the reinforcing and reducing manipulation at different acupoints]. (United States)

    Dai, Qing; Sheng, Xiesun; Chen, Feng


    The reinforcing and reducing manipulation at different acupoints is a kind of acupuncture manipulations and has satisfactory clinical therapeutic effects, combined with a proper needling techniques. The reinforcing needling method is used in the upper and the reducing one in the lower, the distal acupoints are combined with the nearby acupoints. The local acupoints or adjcant acupoints of the affected area are regarded as the nearby acupoints, e.g. the acupoints in the upper. The distant acupoints and the acupoints on the hand and foot are named as distal acupoints, e.g. the acupoint in the lower. In the reinforcing manipulation, the needle is inserted shallowly along the running direction of meridian. In the reducing manipulation, the needle is inserted deeply and against the running direction of meridian. The yin - yang couple needling technique is used with the combination of the front- mu and back- shu points. In the first option, the reinforcing and reducing needling method with rotating technique is predominated at the front- mu points, while that with lifting and thrusting technique is at the back- shu points. In the second option, when needling the back- shu points, the needling sensation is transmitted along the transverse segment and far to the chest and abdomen. These two kinds of integration of acupoint combination and needling techniques display a certain clinical significance in improving the therapeutic effects of acupuncture.

  9. Corneal topography with an aberrometry-topography system. (United States)

    Mülhaupt, Michael; Dietzko, Sven; Wolffsohn, James; Bandlitz, Stefan


    To investigate the agreement between the central corneal radii and corneal eccentricity measurements generated by the new Wave Analyzer 700 Medica (WAV) compared to the Keratograph 4 (KER) and to test the repeatability of the instruments. 20 subjects (10 male, mean age 29.1 years, range 21-50 years) were recruited from the students and staff of the Cologne School of Optometry. Central corneal radii for the flat (r c/fl ) and steep (r c/st ) meridian as well as corneal eccentricity for the nasal (e nas ), temporal (e temp ), inferior (e inf ) and superior (e sup ) directions were measured using WAV and KER by one examiner in a randomized order. Central radii of the flat (r c/fl ) and steep (r c/st ) meridian measured with both instruments were statically significantly correlated (r = 0.945 and r = 0.951; p  0.05). Limits of agreement (LoA) indicate a better repeatability for the KER compared to WAV. Corneal topography measurements captured with the WAV were strongly correlated with the KER. However, due to the differences in measured corneal radii and eccentricities, the devices cannot be used interchangeably. For corneal topography the KER demonstrated better repeatability.

    Bandlitz, Stefan; Bäumer, Joachim; Conrad, Uwe; Wolffsohn, James


    A detailed evaluation of the corneo-scleral-profile (CSP) is of particular relevance in soft and scleral lenses fitting. The aim of this study was to use optical coherence tomography (OCT) to analyse the profile of the limbal sclera and to evaluate the relationship between central corneal radii, corneal eccentricity and scleral radii. Using OCT (Optos OCT/SLO; Dunfermline, Scotland, UK) the limbal scleral radii (SR) of 30 subjects (11M, 19F; mean age 23.8±2.0SD years) were measured in eight meridians 45° apart. Central corneal radii (CR) and corneal eccentricity (CE) were evaluated using the Oculus Keratograph 4 (Oculus, Wetzlar, Germany). Differences between SR in the meridians and the associations between SR and corneal topography were assessed. Median SR measured along 45° (58.0; interquartile range, 46.8-84.8mm) was significantly (ptopography and may provide additional data useful in fitting soft and scleral contact lenses.

  11. Surgically induced astigmatism after phacoemulsification with and without correction for posture-related ocular cyclotorsion: randomized controlled study.

    LENUS (Irish Health Repository)

    Dooley, Ian


    PURPOSE: To report the impact of posture-related ocular cyclotorsion on one surgeon\\'s surgically induced astigmatism (SIA) results and the variance in SIA. SETTING: Institute of Eye Surgery, Whitfield Clinic, Waterford, Ireland. METHODS: This prospective randomized controlled study included eyes that had phacoemulsification with intraocular lens implantation. Eyes were randomly assigned to have (intervention group) or not have (control group) correction for posture-related ocular cyclotorsion. In the intervention group, the clear corneal incision was placed precisely at the 120-degree meridian with instruments designed to correct posture-related ocular cyclotorsion. In the control group, the surgeon endeavored to place the incision at the 120-degree meridian, but without markings. RESULTS: The intervention group comprised 41 eyes and the control group, 61 eyes. The mean absolute SIA was 0.74 diopters (D) in the intervention group and 0.78 D in the control group; the difference between groups was not statistically significant (P>.5, unpaired 2-tailed Student t test). The variance in SIA was 0.29 D(2) and 0.31 D(2), respectively; the difference between groups was not statistically significant (P>.5, unpaired F test). CONCLUSIONS: Attempts to correct for posture-related ocular cyclotorsion did not influence SIA or its variance in a single-surgeon series. These results should be interpreted with full appreciation of the limitations of currently available techniques to correct for posture-related ocular cyclotorsion in the clinical setting.

  12. Interhemispheric Asymmetry of the Sunward Plasma Flows for Strongly Dominant IMF BZ > 0 (United States)

    Yakymenko, K. N.; Koustov, A. V.; Fiori, R. A. D.


    Super Dual Auroral Radar Network (SuperDARN) convection maps obtained simultaneously in both hemispheres are averaged to infer polar cap ionospheric flow patterns under strongly dominant positive interplanetary magnetic field (IMF) Bz component. The data set consisted of winter observations in the Northern Hemisphere simultaneously with summer observations in the Southern Hemisphere. Long-lasting high-latitude dayside reverse convection cells are shown to have faster sunward flows at near-magnetic noon hours in the summer/Southern Hemisphere. Sunward flows typically deviate from the midnight-noon meridian toward 10-11 h of magnetic local time in the summer/Southern Hemisphere and are more aligned with the midnight-noon meridian in the winter/Northern Hemisphere. Flow deviations in the winter/Northern Hemisphere can be both toward prenoon and postnoon hours, and there is no clear relationship between flow deviation and the IMF By component. No strong preference for the sunward flow occurrence depending on the IMF Bx polarity was found. In addition, the rate of the sunward flow speed increase in response to an increase in driving conditions was found to be comparable for the IMF Bx > 0 and Bx < 0.

  13. [Professor WANG Yin's academic thoughts and clinical application of acupuncture for spleen-sto-mach care]. (United States)

    Niu, Hua; Cao, Haibo; Wang, Yin

    Professor WANG Yin 's academic thoughts and clinical application for difficult and miscellaneous di-seases, especially acupuncture for spleen-stomach care, are introduced. Based on TCM basic theory and "ten needles for elderly" by WANG Yueting , Professor WANG Yin proposes the acupuncture for spleen-stomach care. In this method, three-element acupoint selection is applied; the conception vessel, spleen meridian of foot taiyin and stomach meridian of foot yangming were selected. The deep and penetration acupuncture with 0.4 mm×100 mm elongated needles is used at Zhongwan (CV 12), Qihai (CV 6) and Zigong (EX-CA 1), and the mild reinforcing-reducing method is used at remaining acupoints. According to the severity of diseases, fire acupuncture combined with blood-letting cupping is applied at Tianshu (ST 25), Xuehai (SP 10) and Yinlingquan (SP 9); gene-rally, two acupoints are selected and 1 to 3 mL blood-letting is appropriate. The modification based on this me-thod can be applied for various difficult and miscellaneous diseases, leading to superior efficacy.

  14. [Professor WU Zhongchao's experience in the treatment of bi syndrome with fire needling therapy at lower he-sea points]. (United States)

    Zhou, Yu; Chen, Zhongjie; Liu, Chun; Wang, Bing; Zhang, Ning; Li, Caifen; Xie, Qian


    Bi syndrome is classified into five categories. Based on the syndrome differentiation of meridians and collaterals and zangfu theories, Professor WU Zhongchao proposed the fire needling therapy at the lower he -sea points for five types of bi syndromes. Professor WU stresses on the flexible application of fire needling therapy for bi syndrome at the lower he -sea points and innovated the unique five techniques of fire needling therapy, named lifting and threating needle of small amplitude at the lower he -sea points, the stimulation along the relevant meri-dians before fire needling, detecting the sensitive sites by gentle pressing the relevant lower he -sea points, combining the movement of affected upper limb or joint during fire needling, or combining with contralateral needling technique, and controlling the depth of fire needling based on the duration of sickness and depth of affected site. He pointed out that Shangjuxu (ST 37) is for skin bi syndrome, Zusanli (ST 36) for muscle bi syndrome, Yanglingquan (GB 34) for tendon bi syndrome, Weizhong (BL 40) for bone bi syndrome and Xiajuxu (ST 39) for vessel bi syndrome.

  15. Characterisation of the porcine eyeball as an in-vitro model for dry eye. (United States)

    Menduni, Francesco; Davies, Leon N; Madrid-Costa, D; Fratini, Antonio; Wolffsohn, James S


    To characterise the anatomical parameters of the porcine eye for potentially using it as a laboratory model of dry eye. Anterior chamber depth and angle, corneal curvature, shortest and longest diameter, endothelial cell density, and pachymetry were measured in sixty freshly enucleated porcine eyeballs. Corneal steepest meridian was 7.85±0.32mm, corneal flattest meridian was 8.28±0.32mm, shortest corneal diameter was 12.69±0.58mm, longest corneal diameter was 14.88±0.66mm and central corneal ultrasonic pachymetry was 1009±1μm. Anterior chamber angle was 28.83±4.16°, anterior chamber depth was 1.77±0.27mm, and central corneal thickness measured using OCT was 1248±144μm. Corneal endothelial cell density was 3250±172 cells/mm 2 . Combining different clinical techniques produced a pool of reproducible data on the porcine eye anatomy, which can be used by researchers to assess the viability of using the porcine eye as an in-vitro/ex-vivo model for dry eye. Due to the similar morphology with the human eye, porcine eyeballs may represent a useful and cost effective model to individually study important key factors in the development of dry eye, such as environmental and mechanical stresses.

  16. Peripheral vision and perceptual asymmetries in young and older martial arts athletes and nonathletes. (United States)

    Muiños, Mónica; Ballesteros, Soledad


    The present study investigated peripheral vision (PV) and perceptual asymmetries in young and older martial arts athletes (judo and karate athletes) and compared their performance with that of young and older nonathletes. Stimuli were dots presented at three different eccentricities along the horizontal, oblique, and vertical diameters and three interstimulus intervals. Experiment 1 showed that although the two athlete groups were faster in almost all conditions, karate athletes performed significantly better than nonathlete participants when stimuli were presented in the peripheral visual field. Experiment 2 showed that older participants who had practiced a martial art at a competitive level when they were young were significantly faster than sedentary older adults of the same age. The practiced sport (judo or karate) did not affect performance differentially, suggesting that it is the practice of martial arts that is the crucial factor, rather than the type of martial art. Importantly, older athletes lose their PV advantage, as compared with young athletes. Finally, we found that physical activity (young and older athletes) and age (young and older adults) did not alter the visual asymmetries that vary as a function of spatial location; all participants were faster for stimuli presented along the horizontal than for those presented along the vertical meridian and for those presented at the lower rather than at the upper locations within the vertical meridian. These results indicate that the practice of these martial arts is an effective way of counteracting the processing speed decline of visual stimuli appearing at any visual location and speed.

  17. The heart field effect: Synchronization of healer-subject heart rates in energy therapy. (United States)

    Bair, Christine Caldwell


    Recent health research has focused on subtle energy and vibrational frequency as key components of health and healing. In particular, intentional direction of bioenergy is receiving increasing scientific attention. This study investigates the effect of the healer's electromagnetic (EM) heart field upon subjects during energy healing as measured by synchronization of heart rates and scores on a Subjective Units of Distress (SUD) scale and a Profile of Mood States (POMS) inventory. A nonequivalent pretest-posttest design was used based on heart rate comparisons between healer and subject and correlated with pre-and posttest SUD and POMS scores. Subjects included those who sat within the 3- to 4-foot "strong" range of the independent variable, the healer's heart field, while performing self-application of WHEE (the wholistic hybrid derived from EMDR [eye movement desensitization and reprocessing], and EFT [emotional freedom technique]), a meridian-based tapping technique (n=50); and those who performed the same process beyond the 15- to 18-foot range of the healer's EM heart field (n=41). The dependent variables were heart rate, SUD, and POMS inventory. All subjects completed these measures within 1 hour. Study results showed statistically significant heart-rate synchronization with the intervention population. In addition, SUD and POMS scores demonstrated considerably more improvement than in the control population, indicating additional benefit beyond the meridian-based therapies, such as WHEE, alone. Additional findings and future research recommendations are presented in this article.

  18. A Modern Clinical Approach of the Traditional Korean Saam Acupuncture

    Directory of Open Access Journals (Sweden)

    Manyong Park


    Full Text Available Saam acupuncture is one of the original therapeutic modalities representing traditional Korean medicine. It was originally described in a manuscript that is estimated to be published at some point between 1644 and 1742, in the middle of the Cho Sun dynasty, by a Korean Buddhist monk whose name is unknown. The principle of combining five shu points is based on the theory of Nan-jing. The treatment and diagnosis concepts in Saam acupuncture were mainly influenced by Dongeuibogam and Chimgoogyeong-heombang. The basic characteristic of combining five shu points in Saam acupuncture is the selection of the tonification and sedation points along the self-meridian and other meridians based on creation and governor relationships. Saam acupuncture clinical studies have mainly focused on musculoskeletal pain and autonomic nervous system regulation. From a neurophysiological perspective, Saam acupuncture, which involves five shu points as the main treatment aspect, has the advantage of increasing parasympathetic nerve activation and adjusting the balance of the autonomic nervous system. Inserting a needle into the skin layer while considering the respiratory phase and stimulating the needle gently and lightly could maximize the effect of Saam acupuncture. The specific Saam acupuncture prescribed should be identified on the basis of the neurobiological perspective.

  19. Topography of ganglion cell production in the cat's retina

    International Nuclear Information System (INIS)

    Walsh, C.; Polley, E.H.


    The ganglion cells of the cat's retina form several classes distinguishable in terms of soma size, axon diameter, dendritic morphology, physiological properties, and central connections. Labeling with [ 3 H]thymidine shows that the ganglion cells which survive in the adult are produced as several temporally shifted, overlapping waves: medium-sized cells are produced before large cells, whereas the smallest ganglion cells are produced throughout the period of ganglion cell generation. Large cells and medium-sized cells show the same distinctive pattern of production, forming rough spirals around the area centralis. The oldest cells tend to lie superior and nasal to the area centralis, whereas cells in the inferior nasal retina and inferior temporal retina are, in general, progressively younger. Within each retinal quadrant, cells nearer the area centralis tend to be older than cells in the periphery, but there is substantial overlap. The retinal raphe divides the superior temporal quadrant into two zones with different patterns of cell addition. Superior temporal retina near the vertical meridian adds cells only slightly later than superior nasal retina, whereas superior temporal retina near the horizontal meridian adds cells very late, contemporaneously with inferior temporal retina. The broader wave of production of smaller ganglion cells seems to follow this same spiral pattern at its beginning and end. The presence of the area centralis as a nodal point about which ganglion cell production in the retinal quadrants pivots suggests that the area centralis is already an important retinal landmark even at the earliest stages of retinal development

  20. Impact of major coronal mass ejections on geo-space during September 7 -- 13, 2005 (United States)

    Wang, Y.; Xue, X.; Shen, C.; Ye, P.; Wang, S.; Zhang, J.


    We have analyzed five major CMEs originating from NOAA active region (AR) 808 during the period of September 7 to 13, 2005, when the AR 808 rotated from the east limb to near solar meridian. Several factors that affect the probability of the CMEs' encounter with the Earth are demonstrated. The solar and interplanetary observations suggest that the 2nd and 3rd CMEs, originating from E67 and E47 respectively, encountered the Earth, while the 1st CME originating from E77 missed the Earth, and the last two CMEs, originating from E39 and E10 respectively, probably only grazed the Earth. Based on our ice-cream cone model (Xue et al. 2005a) and CME deflection model (Wang et al. 2004b), we find that the CME span angle and deflection are important for the probability of encountering. The large span angles make middle two CMEs hit the Earth, though their source locations were not close to the solar central meridian. The significant deflection makes the first CME totally missed the Earth though it also had wide span angle. The deflection may also make the last CME nearly missed the Earth though it originated close to the disk center. We suggest that, in order to effectively predict whether a CME will encounter the Earth, the factors of the CME source location, the span angle, and the interplanetary deflection should all be taken into account.

  1. [Discussion on the key points of building modern theory of acupuncture treatment]. (United States)

    Yang, Guang


    Acupuncture treatment is different from treatment of materia medica. However, syndrome differentiation system of internal medicine is adopted all the time for the present acupuncture textbooks. It is held that the characteristics of acupuncture can not be fully reflexed, and advantages of acupuncture can not be brought into full play. Therefore, it's urgent to build up a modem theory on acupuncture treatment which is fit for the clinical practice of acupuncture and can give a better play for the treatment of acupuncture. A clear target is one of the characteristics of acupuncture treatment. And it is based on the understanding of the location of disease, therefore, disease differentiation is held as the basis of acupuncture treatment. The aim of meridian differentiation is to select distal effective points on the base of diseases differentiation, which is also taken as the characteristics of acupuncture treatment. Syndrome differentiation is a process of understanding the general pathological states of the human body, it is an important process to enhance the therapeutic effect of acupuncture. Thus, the key point for establishing the modern acupuncture theory is clarifying the values of disease differentiation, meridian differentiation and syndrome differentiation.

  2. Correlated observations of several auroral substorms on February 17, 1971

    Hones, E.W. Jr.; Akasofu, S.; Wolcott, J.H.; Bame, S.J.; Fairfield, D.H.; Meng, C.


    The purpose of this study is to correlate in detail auroral activity with the corresponding disturbances in the magnetotail. The auroral data were recorded by optical instruments aboard an airplane flying over the Arctic Ocean along the Alaska meridian and by the Alaska meridian chain of all-sky cameras. The corresponding magnetotail observations were made by various instruments on Vela 6A and Imp 5; the interplanetary magnetic field was monitored concurrently by Explorer 35 (Imp E). Three successive substorms were observed on February 17, 1971. Each substorm was readily identified by the classical auroral and magnetic signatures which accompanied its onset. The observed variations of plasma and magnetic field in the magnetotail were consistent with the idea that a neutral line formed in the range approx.-12 R/subE/>X/subS//subM/>-18 R/subE/ at the onset of each substorm expansive phase and then moved tailward past X/subS//subM/=-18 R/subE/ some tens of minutes afterward. The Z component of the tail magnetic field decreased rather steadily for a period of 1--21/2 hours after each substorm and until the onset of the next expansive phase, reaching a minimum value just before each onset. This taillike development of the field is more appropriately regarded as the normal evolutionary pattern of variation between substorms than as a 'growth phase' preceding each substorm

  3. Use of mobile application: Means of communication between Parents and Class Teacher

    Full Text Available Collaboration in between parents and teachers is an important step for student’s achievement. Stakeholders in education sector are trying to find best solution to encourage parents’ involvement in school activities. To involve parents in schooling activities and in other events, a good info-notice system should be established. Teachers should give exact information about any student’s progress as well as other information. In Nepal, most of the schools use notebook called “communication book or school diary as the means of communication with parents”. This traditional and most known system is still being used in many parts of the country. Class Teacher writes down a note or notice to parents on it about any information of current activities or forth coming events. The use of mobile applications has been increasing rapidly, and is being used in many aspects in education. The aim of this study is to investigate parents’ view on using mobile application to communicate with teachers. The Meridian Connect mobile application, which has been widely coming in use in between parents and class teachers, is used for this research. The study was designed to apply the questionnaire based survey methodology in which 573 parents of the students of Meridian International School were asked.. The results of data analysis indicated that parents’ view on the use of mobile application to upgrade the education environment has been proved to be positive and useful

  4. [Study on medical records of acupuncture-moxibustion in The Twenty-four Histories]. (United States)

    Huang, Kai-Wen


    Through the combination of manual retrieval and computerized retrieval, medical records of acupuncture-moxibustion in The Twenty-Four Histories were collected. Acupuncture cases from the Spring and Autumn Period (770-476 B.C.) to the end of the Ming Dynasty (1368-1644)were retrieved. From the medical records of acupuncture-moxibustion in Chinese official history books, it can be found that systematic diseases or emergent and severe diseases were already treated by physicians with the combination of acupuncture and medicine as early as in the Spring and Autumn Period as well as the Warring States Period(475-221 B.C.). CANG Gong, a famous physician of the Western Han Dynasty (206 B. C.-A. D. 24), cured diseases by selecting points along the running courses of meridians where the illness inhabited, which indicates that the theory of meridians and collaterals was served as a guide for clinical practice as early as in the Western Han Dynasty. Blood letting therapy, which has surprising effect, was often adopted by physicians of various historical periods to treat diseases. And treatment of diseases with single point was approved to be easy and effective.

  5. Was acupuncture developed by Han Dynasty Chinese anatomists? (United States)

    Shaw, Vivien; Mclennan, Amy K


    Anatomical dissection has begun to reveal striking similarities between gross anatomical structures and the system of nomenclature used in traditional Chinese acupuncture. This paper argues that acupuncture point nomenclature is rooted in systematic anatomical investigation of cadaveric specimens, and that acupuncture points and meridians are purposefully named to reflect observable physical form. Two types of evidence are compared: observations of physical structures based on anatomical dissection, and translation and analysis of original Chinese texts. Evidence is contextualized through in-depth practical understanding of acupuncture. Points designated as [Chinese character] tian (heavenly/superior), [Chinese character] xia (below/inferior), [Chinese character] liao (bone-hole), [Chinese character] fei (flying), [Chinese character] wei (bend), and [Chinese character] xi (mountain stream/ravine) are investigated. These acupuncture point names: (a) specify position; (b) reflect function and/or form; (c) indicate homologous structures; (d) mark unusual structures; and/or (e) describe the physical appearance of a deep (dissected) structure by likening it to a homologous everyday object. Results raise intriguing possibilities for developing an understanding of acupuncture points and meridians firmly based in the material and functional anatomy of the human body. Such an understanding has the potential to open new fields of thought about functional anatomy. It also has implications for future investigations into the mechanisms of acupuncture, and gives some insights into the possible origins of this iconic area of Chinese medicine. © 2016 Wiley Periodicals, Inc.

  6. Effect of ocular transverse chromatic aberration on detection acuity for peripheral vision. (United States)

    Cheney, Frank; Thibos, Larry; Bradley, Arthur


    We examined the effect of transverse chromatic aberration (TCA) on detection acuity for white-light interference fringes seen in Maxwellian view at various orientations and locations in the visual field. A circular patch (3.5° diameter, 3.2 log Trolands) of nominally high-contrast fringes was produced on the retina by a commercial instrument (the Lotmar Visometer, Haag Streit) mounted on a gimbal for controlled positioning of the stimulus in the visual field from 0° to 35° eccentricity. Detection acuity for white light fringes for all meridians and eccentricities ≥15° was maximum when fringes were oriented parallel to the visual meridian line. This meridional effect disappeared when a narrow-band filter was used to eliminate TCA. The meridional effect also disappeared when the interferometric stimulator was displaced laterally to align the instrument with the eye's local achromatic axis. Modelling confirmed that TCA is the major factor responsible for white-light meridional bias, with minor contribution arising from higher-order monochromatic aberrations and neural factors. © 2014 The Authors Ophthalmic & Physiological Optics © 2014 The College of Optometrists.

  7. Visuotopic organization of the cebus pulvinar: a double representation the contralateral hemifield. (United States)

    Gattass, R; Oswaldo-Cruz, E; Sousa, A P


    The projection of the visual field in the pulvinar nucleus was studied in 17 Cebus monkeys using electrophysiological techniques. Visual space is represented in two regions of the pulvinar; (1) the ventrolateral group, Pvlg, comprising nuclei P delta, P delta, P gamma, P eta and P mu 1; and (2) P mu. In the first group, which corresponds to the pulvinar inferior and ventral part of the pulvinar lateralis, we observed a greater respresentation of the central part of the visual field. Approximately 58% of the volume of the ventrolateral group is concerned with the visual space within 10 degrees of the fovea. This portion of the visual field is represented at its lateral aspects, mainly close to the level of the caudal pole of the lateral geniculate nucleus (LGN). Projection of the vertical meridian runs along its lateral border while that of the horizontal one is found running from the dorsal third of the LGN's hilus to the medial border of the ventro-lateral group. The lower quadrant is represented at its dorsal portion while the upper quadrant is represented at the ventral one. In Pmu the representation is rotated 90 degrees clockwise around the rostrocaudal axis: the vertical meridian is found at the ventromedial border of this nucleus. Thus, the lower quadrant is represented at the later portion of Pmu and the upper at its medial portion. Both projections are restricted to the contralateral hemifield.

  8. Relative contribution of ionospheric conductivity and electric field to the auroral electrojets

    International Nuclear Information System (INIS)

    Kamide, Y.; Vickrey, J.F.


    Data from continuous scans of the Chatanika radar beam along the magnetic meridian plane are used to the determine the latitudinal profile of height-integrated ionospheric conductivities and horizontal electric fields, from which the latitudinal distribution of ionospheric currents is deduced. The observations cover invariant latitudes between 62 0 and 68 0 , where the IMS Alaska meridian chain of magnetometers was also in operation. Although the conductivities and the electric fields are interrelated, the relative importance of the two in driving the eastward and westward auroral electrojet currents can be assessed. It is found that for moderate and large current densities (i.e., > or approx. =0.2 A/m), the northward electric field strength increases as the magnitude of the eastward electrojet in the evening sector increases. The height-integrated Hall conductivity stays generally at the level of 10 mhos even when the current density becomes as large as 1 A/m. However, when the eastward electrojet is small, substantial electric fields of 10-20 mV/m may still exist as if the magnetosphere has a persistent voltage source. There appear to be two distinct components to the westward electrojet. In the midnight and early morning sestors (>0300 MLT) intensity is characterized by a weak southward electric field and a high Hall conductivity, whereas its late morning portion (>0300 MLT) is dominated by a strong southward electric field

  9. Early and late inhibitions elicited by a peripheral visual cue on manual response to a visual target: Are they based on Cartesian coordinates?

    Directory of Open Access Journals (Sweden)

    Fábio V. Magalhães


    Full Text Available A non-informative cue (C elicits an inhibition of manual reaction time (MRT to a visual target (T. We report an experiment to examine if the spatial distribution of this inhibitory effect follows Polar or Cartesian coordinate systems. C appeared at one out of 8 isoeccentric (7o positions, the C-T angular distances (in polar coordinates were 0º or multiples of 45º and ISI were 100 or 800ms. Our main findings were: (a MRT was maximal when C- T distance was 0o and minimal when C-T distance was 180o and (b besides an angular distance effect, there is a meridian effect. When C and T occurred in the same quadrant, MRT was longer than when T and C occurred at the same distance (45o but on different sides of vertical or horizontal meridians. The latter finding indicates that the spatial distribution of the cue inhibitory effects is based on a Cartesian coordinate system.

  10. The Peculiar Behavior of Halo Coronal Mass Ejections in Solar Cycle 24 (United States)

    Gopalswamy, N.; Xie, H.; Akiyama, S.; Makela, P.; Yashiro, S.; Michalek, G.


    We report on the remarkable finding that the halo coronal mass ejections (CMEs) in cycle 24 are more abundant than in cycle 23, although the sunspot number in cycle 24 has dropped by approx. 40%. We also find that the distribution of halo-CME source locations is different in cycle 24: the longitude distribution of halos is much flatter with the number of halos originating at a central meridian distance greater than or equal to 60deg twice as large as that in cycle 23. On the other hand, the average speed and associated soft X-ray flare size are the same in both cycles, suggesting that the ambient medium into which the CMEs are ejected is significantly different. We suggest that both the higher abundance and larger central meridian longitudes of halo CMEs can be explained as a consequence of the diminished total pressure in the heliosphere in cycle 24. The reduced total pressure allows CMEs to expand more than usual making them appear as halos.

  11. Comparing ImmunoCard with two EIA assays for Clostridium difficile toxins. (United States)

    Chan, Edward L; Seales, Diane; Drum, Hong


    To compare three Clostridium difficile EIA kits for the detection of C. difficile toxins from clinical specimens. A total of 287 fresh and stored stool specimens were tested using all three assays. Stools with discrepant results were sent to a reference laboratory for tissue cytotoxin assay. Trinity Medical Center, a community hospital with network hospitals. Patients with diarrhea submitted stools for detection of C. difficile toxins. Of the 287 stool specimens, 116 were positive and 171 negative for C. difficile toxins. The sensitivity, specificity, and positive and negative predictive values of Meridian EIA assay were 99.1, 97.7, 96.6, and 99.4%; ImmunoCard were 100, 98.2, 97.5, and 100%; BioStar OIA assay were 94, 98.8, 98.2, and 96% respectively. ImmunoCardprovides the best sensitivity (100%) for C. difficile toxins A and B detection. The BioStar OIA rapid test missed seven positive stool specimens possibly due to failure to detect toxin B. ImmunoCard has slightly higher predictive values, shorter turnaround time and greater convenience compared to the Meridian EIA Assay. ImmunoCard may be cost effective not only in smaller laboratories, but also in high volume laboratories, when used on a STAT basis or single request.

  12. Relationship between full-thickness macular hole and retinal break/lattice degeneration. (United States)

    Zhang, Jinglin; Li, Yonghao; Zhao, Xiujuan; Cai, Yu; Yu, Xiling; Lu, Lin


    The purpose is to investigate the relationship between full-thickness macular hole (MH) and retinal break (RB) and/or lattice degeneration. Patients diagnosed as full-thickness MH and referred to Dr. Lin Lu from January 2009 to December 2013 were evaluated. All patients underwent general ophthalmologic examinations, fundus examination and optical coherence tomography (OCT). The RB and/or lattice degeneration were recorded. Totally 183 eyes of 167 patients were included. The sex ratio of men to women was 1:2.88. A total of 17 eyes were pseudophakic and 166 eyes were phakic. RB and/or lattice degeneration were found in 62 eyes (33.88%). The prevalence of RB and/or lattice degeneration was similar between men and women (P = 0.344 > 0.05). There was no statistical difference between the pseudophakic eyes and phakic eyes (P = 0.138 > 0.05). All of the RB and/or lattice degeneration were located near or anterior to the equator. The inferior quadrants and the vertical meridian were affected more often than the superior quadrants and the horizontal meridian. We identified a high incidence of RB/lattice degeneration in cases of full-thickness MH. Carefully examination of the peripheral retina and prophylactic treatment of RB and/or lattice degeneration are critical.

  13. On solution of Lame equations in axisymmetric domains with conical points

    International Nuclear Information System (INIS)

    Nkemzi, Boniface


    Partial Fourier series expansion is applied to the Dirichlet problem for the Lame equations in axisymmetric domains Ω-circumflex is a subset of R 3 with conical points on the rotation axis. This leads to dimension reduction of the three-dimensional boundary value problem resulting to an infinite sequence of two-dimensional boundary value problems on the plane meridian domain Ω a is a subset of R + 2 of Ω-circumflex with solutions u n (n = 0,1,2, ...) being the Fourier coefficients of the solution u-circumflex of the 3D BVP. The asymptotic behavior of the Fourier coefficients u n (n = 0,1,2, ...) near the angular points of the meridian domain Ω a is fully described by singular vector-functions which are related to the zeros α n of some transcendental equations involving Legendre functions of the first kind. Equations which determine the values of α n are given and a numerical algorithm for the computation of α n is proposed with some plots of values obtained presented. The singular vector functions for the solution of the 3D BVP is obtained by Fourier synthesis. (author)

  14. Investigation of conditions for the generation and propagation of low-frequency disturbances in the troposphere (United States)

    Mordvinov, V. I.; Devyatova, E. V.; Kochetkova, O. S.; Oznobikhina, O. A.


    Low-frequency disturbances responsible for the excitation of torsional oscillations—variations in the zonal mean flow intensity with a characteristic scale of 15-20 days—propagating along the meridian at mid and low latitudes of both hemispheres are investigated [1]. As data observed over the eastern parts of continents and the western parts of oceans are processed with the lag correlation statistics, traveling waves intersecting the eastern parts of continents from northwest to southeast and then returning to the north along the ocean coasts are identified. In this case, trains of anomalies oriented in the zonal direction periodically appear and are destructed in the western parts of continents. The simulation of the propagation of disturbances in the quasi-geostrophic approximation made it possible to explain the specific features of lag correlation statistics over continents by the dispersion of two-dimensional Rossby waves from traveling sources. The turnover of disturbances over Asia and wave trains to the west from the pole were reproduced. Torsional oscillations caused by the dispersion of two-dimensional Rossby waves have a characteristic form of inclined bands in the latitude-time diagram, whose steepness is controlled by the velocity of displacement of the vorticity source along the meridian.

  15. Automatic focusing of attention on object size and shape

    Directory of Open Access Journals (Sweden)

    Cesar Galera


    Full Text Available In two experiments we investigated the automatic adjusting of the attentional focus to simple geometric shapes. The participants performed a visual search task with four stimuli (the target and three distractors presented always around the fixation point, inside an outlined frame not related to the search task. A cue informed the subject only about the possible size and shape of the frame, not about the target. The results of the first experiment showed faster target detection in the valid cue trials, suggesting that attention was captured automatically by the cue shape. In the second experiment, we introduced a flanker stimulus (compatible or incompatible with the target in order to determine if attentional resources spread homogenously inside and outside the frame. The results showed that performance depended both on cue validity and frame orientation. The flanker effect was dependent on compatibility and flanker position (vertical or horizontal meridian. The results of both experiments suggest that the form of an irrelevant object can capture attention despite participants’ intention and the results of the second experiment suggest that the attentional resources are more concentrated along the horizontal meridian.

  16. 1H NMR Metabolic Profiling of Biofluids from Rats with Gastric Mucosal Lesion and Electroacupuncture Treatment

    Directory of Open Access Journals (Sweden)

    Jingjing Xu


    Full Text Available Gastric mucosal lesion (GML is a common gastrointestinal disorder with multiple pathogenic mechanisms in clinical practice. In traditional Chinese medicine (TCM, electroacupuncture (EA treatment has been proven as an effective therapy for GML, although the underlying healing mechanism is not yet clear. Here, we used proton nuclear magnetic resonance- (1H NMR- based metabolomic method to investigate the metabolic perturbation induced by GML and the therapeutic effect of EA treatment on stomach meridian (SM acupoints. Clear metabolic differences were observed between GML and control groups, and related metabolic pathways were discussed by means of online metabolic network analysis toolbox. By comparing the endogenous metabolites from GML and GML-SM groups, the disturbed pathways were partly recovered towards healthy state via EA treated on SM acupoints. Further comparison of the metabolic variations induced by EA stimulated on SM and the control gallbladder meridian (GM acupoints showed a quite similar metabolite composition except for increased phenylacetylglycine, 3,4-dihydroxymandelate, and meta-hydroxyphenylacetate and decreased N-methylnicotinamide in urine from rats with EA treated on SM acupoints. The current study showed the potential application of metabolomics in providing further insight into the molecular mechanism of acupuncture.

    During the first year of the grant, we participated in three WOCE expeditions (a total of 152 days at sea) in the South Pacific Ocean, and the field phase of the proposed investigation has been successfully completed. The total CO 2 concentration and pCO 2 were determined at sea in 4419 water samples collected at 422 stations. On the basis of the shipboard analyses of SIO Reference Solutions for CO, and a comparison with the results of previous expeditions, the overall precision of our total CO 2 determinations is estimated to be about ±2 uM/kg. The deep water data indicate that there is a CO 2 maximum centered about 2600 meters deep. This appears to represent a southward return flow from the North Pacific. The magnitude and distribution of the CO, maximum observed along the 135.0 degrees W meridian differ from those observed along the 150.5 degrees W meridian due to Tuamotu Archipelago, a topographic high which interferes with the southward return flow. The surface water pCO 2 data indicate that the South Pacific sub-tropical gyre water located between about 15 degrees S and 50 degrees S is a sink for atmospheric CO 2

    To assess the decentration and angle of tilt of the intraocular lens (IOL) according to the intravitreal tamponade types used in combined phacoemulsification and vitreoretinal surgery. This prospective and randomized clinical study involved 73 eyes of 69 patients who underwent combined vitreoretinal surgery. Eyes with intravitreal tamponades formed the study group and eyes without intravitreal tamponades formed the control group. The study group was further divided into silicone oil and gas tamponade subgroups. Cross-sectional IOL images were captured using a Pentacam HR (Oculus, Germany) and tilt and decentration were calculated with Adobe Photoshop software (Adobe, San Jose, CA). The mean angle of tilt and decentration at the vertical meridian were significantly higher in both tamponade groups than in the control group (P 0.05). When comparing the silicone oil and gas tamponade subgroups, no significant differences were noted on the position of IOL at both meridians (P > 0.05 for all). Intravitreal tamponades have an important effect on the position of IOL in combined vitreoretinal surgery. Silicone oil and gas tamponades may induce postoperative tilt and decentration of one-piece acrylic IOLs.

  19. [Analysis on composition and medication regularities of prescriptions treating hypochondriac pain based on traditional Chinese medicine inheritance support system inheritance support platform]. (United States)

    Zhao, Yan-qing; Teng, Jing


    To analyze the composition and medication regularities of prescriptions treating hypochondriac pain in Chinese journal full-text database (CNKI) based on the traditional Chinese medicine inheritance support system, in order to provide a reference for further research and development for new traditional Chinese medicines treating hypochondriac pain. The traditional Chinese medicine inheritance support platform software V2. 0 was used to build a prescription database of Chinese medicines treating hypochondriac pain. The software integration data mining method was used to distribute prescriptions according to "four odors", "five flavors" and "meridians" in the database and achieve frequency statistics, syndrome distribution, prescription regularity and new prescription analysis. An analysis were made for 192 prescriptions treating hypochondriac pain to determine the frequencies of medicines in prescriptions, commonly used medicine pairs and combinations and summarize 15 new prescriptions. This study indicated that the prescriptions treating hypochondriac pain in Chinese journal full-text database are mostly those for soothing liver-qi stagnation, promoting qi and activating blood, clearing heat and promoting dampness, and invigorating spleen and removing phlem, with a cold property and bitter taste, and reflect the principles of "distinguish deficiency and excess and relieving pain by smoothening meridians" in treating hypochondriac pain.

  20. An Einstein survey of the 1 keV soft X-ray background in the Galactic plane (United States)

    Stanford, John M.; Caillault, Jean-Pierre


    We have analyzed 56 Einstein Observatory Imaging Proportional Counter (IPC) observations within +/- 3 deg of the Galactic plane in order to determine the low-latitude soft X-ray background flux in the 0.56-1.73 keV band. Any detected X-ray point source which fell within our regions of study was removed from the image, enabling us to present maps of the background flux as a function of Galactic latitude along 18 meridians. These maps reveal considerable structure to the background in the Galactic plane on an angular scale of approximately 1 deg. Our results are compared with those of an earlier study of the 1 keV X-ray background along l = 25 deg by Kahn & Caillault. The double-peaked structure they found is not discernible in our results, possibly because of the presence of solar backscattered flux in their data. A model which takes into account contributions to the background by extragalactic and stellar sources, the distribution of both atomic and molecular absorbing material with the Galaxy, the energy dependence of the cross section for absorption of X-rays, and the energy dependence of the detector has been constructed and fitted to these new data to derive constraints on the scale height, temperature, and volume emissivity of the unaccounted-for X-ray-emitting material. The results of this model along l = 25 deg are roughly similar to those of the model of Kahn & Caillault along the same meridian.

  1. Acupuncture analgesia: The complementary pain management in dentistry

    Directory of Open Access Journals (Sweden)

    Abdurachman Abdurachman


    Full Text Available Background: Pain is the most common reason for medical consultation in the United States. Pain is a major symptom in many medical conditions, and can significantly interfere with a person’s quality of life and general functioning. One of the very unpleasant pain is toothache. Conventional treatments for toothache are improving oral hygiene, prescribing analgesics, anti-inflammatory, and also antibiotics if there are infection even extractions are performed if necessary. Another way to conventional approaches, patients may consider acupuncture method. Acupuncture involves the insertion of needles with the width of a human hair along the precise points throughout the body. This process triggers body’s energy normal flow through extra anatomy pathway called meridian. Purpose: This case report is aimed to emphasize the existence of teeth-organ relationships through communication channels outside the lines of communication that has been known in anatomy. Case: Two patients with toothache complaints in the lower right molars came to an acupuncturist who was a medical practitioner. In these cases pain were relieved by acupuncture analgesia. Case management: Two patients were subjected to acupuncture analgesia with different acupuncture points that were customized to the affected tooth, case 1 with the large intestine-4 (Li-4 which located in the hand and case 2 with bladder-25 (Bl-25 which located in the back of the body. Ninety percent of pain was relieved in 40 seconds. Conclusion: Pain in toothache can be relieved using acupuncture analgesia technique, using meridian as an extra anatomy pathway. Nevertheless, treating the source of pain by dental practitioner is mandatory.Latar belakang: Nyeri adalah alasan paling umum yang menyebabkan orang datang berkonsultasi kepada profesional medis di Amerika Serikat.

  2. The validity and reliability of the handheld SW-100 autokeratometer

    Directory of Open Access Journals (Sweden)

    Eghosasere Iyamu


    Full Text Available Background: The agreement of new instruments or clinical tests with other instruments or tests defines the possibility of these being used interchangeably. Aim: To investigate the validity and reliability of the SW-100 autokeratometer using a Bausch & Lomb (B&L keratometer as the ‘gold standard’. Methods: Eighty subjects (80 right eyes aged between 21 and 38 years were recruited. For intra-test repeatability, two measurements of the corneal radius of curvature were taken with the SW-100 and B&L keratometers. Forty of the 80 subjects participated in the inter-test repeatability measurement. Results: Corneal radius of curvature was found to be statistically different between the two instruments (p < 0.001, with the SW-100 providing slightly flatter values of 0.11 mm and 0.05 mm for the horizontal and vertical meridians, respectively, than the B&L keratometer. The average corneal curvature was 0.07 mm flatter with the SW-100 autokeratometer than with the B&L device. Agreement between the SW-100 and B&L keratometers’ axes was 45% within ± 5°, 60.3% within ± 10°, 78.8% within ± 15°, 80.3% within ± 20°, and 88.7% within ± 40°. Intertest repeatability was better for the B&L device than the SW-100 and showed no significant difference between the two sessions. Both instruments demonstrated comparable intrasession repeatability. As such, both instruments were comparatively reliable (per coefficients of repeatability. The range of limits of agreement of ± 0.14 mm (horizontal meridian and ± 0.17 mm (vertical meridian between the SW-100 and B&L devices showed good agreement. Conclusion: The results suggest that the SW-100 autokeratometer is a reliable and objective instrument that, however, provides flatter radii of curvature measurements than the B&L keratometer. A compensating factor incorporated into the instrument could reduce the difference between the two instruments and make them more interchangeable.

  3. Candidates of World Heritage Sites of Astronomy in Japan (United States)

    Watanabe, Jun-ichi; Nakagiri, Masao


    Unfortunately there is no heritage site of astronomy until now in Japan. Here we report several candidates based on the importance from the historical point of view.One is the “Nisshinkan” Astronomical Observatory site of the Edo era. Many observatories were established in the Edo era, including "Asakusa observatory" of a Shogunate Government. However, most of them have been disappeared by the urban development. The only one remained until now is the “Nissshinkan” Astronomical Observatory site of which the basement made of stones is preserved. This was made in 1803 mainly for educational purpose at the “Nisshinkan” which was a local school for the Samurai’s children in Aizu area. Although a wooden building of the school was lost by a war, but this observatory mark exists because large basement of a few meters high remained. This site is now designated as a cultural asset by the local government, and can be recognized even at the present time.Another is the Repsold Meridian Transit which was designated as the Important Cultural Property of Japan in 2011. A Repsold meridian transit instrument is a telescope with a diameter of 13.5 cm and a focal length of 212 cm for meridian transit observations. It was manufactured by A. Repsold & Soehne Co. Ltd. in Hamburg, Germany in 1880, and purchased by the Naval Observatory and imported to Japan in 1881, becoming one of the most important telescopes in the dawning era of modern astronomy in Japan. The telescope escaped being damaged in the Great Kanto Earthquake, and continued to be used as a main telescope for time determination, longitude observation, and astrometry of heavenly bodies till the end of the 1950s. We confirmed that this telescope has retained its original form in 2008, and after restoration and repair, the telescope was widely opened for exhibition to the public. In June, 2011 it was designated as one of the important cultural properties of Japan. The related old instruments which brought modern

    Zhao, Chang-Long; Jing, Xiang-Hong; Li, Yu-Qing; Li, Liang; Rong, Pei-Jing; Wang, Chang-En


    In the present paper, the authors introduce the approved and finished research projects for acupuncture and moxibustion therapies supported by the National Natural Science Foundation of China (NSFC) during the 11th 5-year-plan. A total of 194 research projects were subsidized by NSFC from 2006 to 2010. These projects include 6 aspects: meridian-collaterals, acupoint theory, acupuncture analgesia, mechanisms underlying improvement of different clinical problems, clinical trials, and moxibustion therapy. The research on acupoints has been becoming a new hotspot in recent years. Majority of the research projects focus on the mechanism of acu-moxibustion underlying improvement of different clinical problems, while fewer projects on clinical trials. During the 11th 5-year-plan, 119 projects were completed; most of them involved meridian-collateral theory, acupoint theory, mechanism of acu-moxibustion underlying improvement of clinical problems and acupuncture manipulations. Following analysis of the finished research projects, we find that 1) many neurobiological methods and techniques are commonly used in the research on meridian-collateral theory; 2) the research on acupoint theory is changing from observing the local morphological structure to identifying characteristics of the regional activated receptors, particularly under the circumstances of visceral pathological conditions and efficacies of acupoints; 3) researches on the underlying mechanism of acu-moxibusiton for improving clinical disorders mainly focused on its cerebral protective effects against cerebral ischemia, in addition, researches about other diseases on clinical conditions have been also carried out, but the related mechanisms are far from understanding; 4) In many research projects, various new methods and techniques, such as fMRI, position emission tomography, genomics, proteomics, molecular biology, nerve stem cell, etc. were widely used; 5) Randomized controlled multi-center clinical trials are

  5. Corrugated Membrane Nonlinear Deformation Process Calculation

    Directory of Open Access Journals (Sweden)

    A. S. Nikolaeva


    Full Text Available Elastic elements are widely used in instrumentation. They are used to create a particular interference between the parts, for accumulating mechanical energy, as the motion transmission elements, elastic supports, and sensing elements of measuring devices. Device reliability and quality depend on the calculation accuracy of the elastic elements. A corrugated membrane is rather common embodiment of the elastic element.The corrugated membrane properties depend largely on its profile i.e. a generatrix of the meridian surface.Unlike other types of pressure elastic members (bellows, tube spring, the elastic characteristics of which are close to linear, an elastic characteristic of the corrugated membrane (typical movement versus external load is nonlinear. Therefore, the corrugated membranes can be used to measure quantities, nonlinearly related to the pressure (e.g., aircraft air speed, its altitude, pipeline fluid or gas flow rate. Another feature of the corrugated membrane is that significant movements are possible within the elastic material state. However, a significant non-linearity of membrane characteristics leads to severe complicated calculation.This article is aimed at calculating the corrugated membrane to obtain the elastic characteristics and the deformed shape of the membrane meridian, as well as at investigating the processes of buckling. As the calculation model, a thin-walled axisymmetric shell rotation is assumed. The material properties are linearly elastic. We consider a corrugated membrane of sinusoidal profile. The membrane load is a uniform pressure.The algorithm for calculating the mathematical model of an axisymmetric corrugated membrane of constant thickness, based on the Reissner’s theory of elastic thin shells, was realized as the author's program in C language. To solve the nonlinear problem were used a method of changing the subspace of control parameters, developed by S.S., Gavriushin, and a parameter marching method

    Tian, Kaiyu; Ma, Qiaolin; Ren, Shan; Liu, Fang


    Bilingual teaching is a innovative method of higher education of China to gear the need of the world. Acupuncture and Moxibustion, a higher international TCM course, has been the model of bilingual teaching in many colleges and universities of TCM successively. To meet the aim and original intention of bilingual education in China, we have supplemented international acupuncture and moxibustion in teaching program for many years. The related contents about acupuncture and moxibustion of World Health Organization (WHO) and International Standardization Organization(ISO) have been added into the chapters of introduction, meridians and acupoints, the technology of acupuncture and moxibustion, the therapy of acupuncture and moxibustion. Teaching international acupuncture and moxibustion not only enlarges the international perspective of students, but also makes them more interested in learning Acupuncture and Moxibustion with a bigger sense of mission.

    Ballegaard, Søren; Pedersen, F; Pietersen, A


    In order to evaluate the effects of acupuncture in moderate, stable angina pectoris, 49 patients were randomized to either genuine or sham acupuncture. In sham acupuncture needles were inserted into points within the same spinal segment as in genuine acupuncture, but outside the Chinese meridian...... system. The effect was evaluated from exercise tests, anginal attack rate and nitroglycerin consumption. There were no significant differences between the effects of genuine and sham acupuncture either on exercise test variables or on subjective variables. In patients receiving genuine acupuncture...... there was a significant increase in exercise tolerance (median 9%) and in delay of onset to pain (median 10%). No significant changes were observed in patients receiving sham acupuncture. Within both groups there was a median reduction of 50% in anginal attack rate and nitroglycerin consumption...

    Libor Severa


    Full Text Available Commercially produced hen eggs have been tested by means of dynamic excitation of the egg-shells with following analysis of their response. The falling steel ball have been chosen as a exciting instrument and the laser vibrometer have been used as a measuring device for the egg response. The reproductibility of the experiments has been relatively high and the surface velocity has been found to be significantly dependent on the position around the meridian. Analysed frequency spectrum has shown the peak frequency and frequency history. Proposed numerical model has demonstrated reasonable agreement with experimental results and can be used as an effective tool in modelling of analogous or similar experiments.

    Jorge Pimentel Cintra


    Full Text Available In this paper, we present a thorough analysis of the Map of the Courts based on criteria used in cartography, particularly mathematical cartography. As such, it takes into account the following elements: author, scale, projection, the prime meridian, colors, conventions, symbology, and other. After a qualitative morphological analysis, we move on to a quantitative examination by comparing the said map with a quite accurate present-day chart, using a digital cartography software application and spreadsheet to match the geographic coordinates (latitude and longitude of over 430 points. The systematic and detailed quantification of errors in various areas, from the Atlantic coast to the Amazon region, revealed surprising aspects as to how skillfully the Map of the Courts was constructed. This analysis enabled us to quantify the distortions more accurately and thus identify the locations where they were introduced as well their unquestionable intentional character.

  11. Experimental tests on buckling of ellipsoidal vessel heads subjected to internal pressure

    International Nuclear Information System (INIS)

    Roche, R.L.; Alix, M.


    Tests were performed on 17 ellipsoidal vessel heads of three different materials and different geometries. The results include the following: 1) Accurate definition of the geometry and particularly a direct measurement of the thickness along the meridian. 2) The properties of the material of each head, obtained from test specimens cut from the head itself after the test. 3) The recording of deflection/pressure curves with indication of the pressure at which buckling occurred. These results can be used for validation and qualification of methods for calculating the buckling load when plasticity occurs before buckling. It was possible to develop an empirical equation representing the experimental results obtained with satisfactory accuracy. This equation may be useful in pressure vessel design

  12. "It feels good to be measured": clinical role-play, Walker Percy, and the tingles. (United States)

    Ahuja, Nitin K


    A large online community has recently formed around autonomous sensory meridian response (ASMR), a pleasant and poorly understood somatic reaction to specific interpersonal triggers. Its web-based manifestations include a variety of amateur videos designed to elicit the reaction, many of which feature protracted imitations of a clinician's physical exam. This analysis considers through a literary lens the proximity of this phenomenon to clinical diagnostics, focusing in particular on characterizations of spiritual isolation elaborated in Love in the Ruins (1971), the third novel by physician-writer Walker Percy (1916-1990). Within this speculative framework, the tendency to derive pleasure from clinical milieus, real or constructed, may be interpreted as a quality particular to the postmodern psyche. Viewing web-based clinical role-play in light of Percy's writing also underscores the possibility that routine diagnostic assessments may have independent therapeutic implications.

  13. A Large-Scale Study of Misophonia. (United States)

    Rouw, Romke; Erfanian, Mercede


    We aim to elucidate misophonia, a condition in which particular sounds elicit disproportionally strong aversive reactions. A large online study extensively surveyed personal, developmental, and clinical characteristics of over 300 misophonics. Most participants indicated that their symptoms started in childhood or early teenage years. Severity of misophonic responses increases over time. One third of participants reported having family members with similar symptoms. Half of our participants reported no comorbid clinical conditions, and the other half reported a variety of conditions. Only posttraumatic stress disorder (PTSD) was related to the severity of the misophonic symptoms. Remarkably, half of the participants reported experiencing euphoric, relaxing, and tingling sensations with particular sounds or sights, a relatively unfamiliar phenomenon called autonomous sensory meridian response (ASMR). It is unlikely that another "real" underlying clinical, psychiatric, or psychological disorder can explain away the misophonia. The possible relationship with PTSD and ASMR warrants further investigation. © 2017 Wiley Periodicals, Inc.

    Fluxgate magnetometers with accurate timing data logger were set up at two equatorial stations (Garous-Marous and Huancayo), and also at a middle latitude station (Kuju). The phase of Pi2 waves is compared among these stations. It is found that 1) Pi2 pulsations in low and equatorial latitudes are linearly polarized approximately along the magnetic meridian, 2) phase difference of the H component of Pi2 waves at different stations is much less than 1 - 10 of the pulsation period despite a large longitudinal separation (∼ 90 deg) of the stations, showing the so-called azimuthal wave number, m, to be much less than unity and 3) phase difference of the D component at different stations is variable.

    Li, Tie; Ha, Lijuan; Cao, Fang; Zhi, Mujun; Wang, Fuchun


    The experience of "Zhenjing Anshen" acupuncture method originally created by professor WANG Fuchun for treatment of insomnia was introduced in this paper. From aspects of insomnia pathogenesis, theoretical foundation, characteristics of acupoint selection, needing methods, needing time, etc., the experience of Professor WANG Fuchun for treatment of insomnia was explained. The "Zhenjing Anshen" acupuncture method proposed, for the first time, "new three layers" method of acupoint selection, including Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6). This method presents the principles of acupoint selection along meridian, acupoint selection based on essence-qi-spirit, harmony of yin and yang. The acupuncture manipulation is emphasized, and treating time (the period of the day from 3 pm to 5 pm) is focused on; acupoint selection is simple but essential, and acupoint combination is scientific, which receives notable therapeutic effect in clinic.

  17. Jean Rotz and the Marine Chart, 1542 (United States)

    Taylor, E. G. R.

    This paper was first published in the Journal in 1954 (Vol. 7, p. 138). It is followed by comments from Michael Richey.At the time (1542) when Jean Rotz presented Henry VIII with a variation compass, and an accompanying treatise on its making and use, the question of magnetic variation was an acute one. It formed part of a wider controversy concerning the general validity of the sea-chart which had been raised among seamen. As to this, Dr Pedro Nunez, writing a treatise in 1537 addressed to his friend and pupil the Infante Dom Luys of Portugal, said that there were skilled pilots who derided the chart and declared it to be - the falsest thing in the world. Hastening to its defence, Nunez dealt at length with the navigating errors introduced by ignoring the convergence of the meridians, and showed besides that a rhumb, or line of constant bearing was a spiral curve on the globe.

  18. Transequatorial magnetic flux loops on the sun: a possible new source of geomagnetic storms

    Directory of Open Access Journals (Sweden)

    Takao Saito


    Full Text Available Following the traditional way of expression, geomagnetic storms have been classified into three types; flare-type Sc storms, CH-type Sg storms, and DB-type Sc storms (Sc:sudden commencement;CH:coronal hole;g:gradual;DB:disparition brusque.We have discovered that some transequatorial loops (TEL give rise to geomagnetic storms, when the TEL explodes near the central meridian of the sun. The axial magnetic direction of the TEL can be inferred, since TELs connect sunspot groups or remnant magnetic regions between the northern and southern hemispheres. Since the axial fields tend to have a large Bz component in interplanetary space, we have examined various effects on the configuration of geomagnetic storms. Topics are proposed for future works on the TEL-type Sc storms.

  19. Differential Deposition for Surface Figure Corrections in Grazing Incidence X-Ray Optics (United States)

    Ramsey, Brian D.; Kilaru, Kiranmayee; Atkins, Carolyn; Gubarev, Mikhail V.; Broadway, David M.


    Differential deposition corrects the low- and mid- spatial-frequency deviations in the axial figure of Wolter-type grazing incidence X-ray optics. Figure deviations is one of the major contributors to the achievable angular resolution. Minimizing figure errors can significantly improve the imaging quality of X-ray optics. Material of varying thickness is selectively deposited, using DC magnetron sputtering, along the length of optic to minimize figure deviations. Custom vacuum chambers are built that can incorporate full-shell and segmented Xray optics. Metrology data of preliminary corrections on a single meridian of full-shell x-ray optics show an improvement of mid-spatial frequencies from 6.7 to 1.8 arc secs HPD. Efforts are in progress to correct a full-shell and segmented optics and to verify angular-resolution improvement with X-ray testing.

  20. Solar rotation and meridional motions derived from sunspot groups

    International Nuclear Information System (INIS)

    Tuominen, J.; Tuominen, I.; Kyroelaeinen, J.


    Latitudinal and longitudinal motions of sunspot groups have been studied using the positions of recurrent sunspot groups of 103 years published by Greenwich observatory. In order to avoid any limb effects, only positions close to the central meridian have been used. The data were divided into two parts: those belonging to the years around sunspot maxima and those belonging to the years around sunspot minima. Using several different criteria it was ascertained that sunspot groups show meridional motions and that their drift curves as a function of latitude are different around maxima and around minima. In addition, also the angular velocity, as a function of latitude, was found to be different around maxima and minima. (Auth.)

  1. A preliminary investigation of the mechanism of anti-pain and counter-injury effects of the acupuncture anaesthesia. (United States)


    In accordance with dialectical materialism and by dint of experimental acupuncture anaesthesia, the present investigation has: (1) Made an objective evaluation of the efficiency of acupuncture anaesthesia. (2) Brought forth some experimental evidence about the material basis of the anti-pain and counter-injury effect of acupuncture anaesthesia as well as the significance of its induction period. (3) Proposed the concept of humoral anaesthesia and its technique in order to improve the efficiency of animal laparotomies with acupuncture anaesthesia. Furthermore, it attempts to offer a theoretical explanation of the process of acupuncture anaesthesia under the combination of Chinese and Western medical theories and thereby gives some support to the "meridian-cerebral cortex-viscera inter-correlation hypothesis."

  2. Response of the convecting high-latitude F layer to a powerful HF wave

    Directory of Open Access Journals (Sweden)

    G. I. Mingaleva


    Full Text Available A numerical model of the high-latitude ionosphere, which takes into account the convection of the ionospheric plasma, has been developed and utilized to simulate the F-layer response at auroral latitudes to high-power radio waves. The model produces the time variations of the electron density, positive ion velocity, and ion and electron temperature profiles within a magnetic field tube carried over an ionospheric heater by the convection electric field. The simulations have been performed for the point with the geographic coordinates of the ionospheric HF heating facility near Tromso, Norway, when it is located near the midnight magnetic meridian. The calculations have been made for equinox, at high-solar-activity, and low-geomagnetic-activity conditions. The results indicate that significant variations of the electron temperature, positive ion velocity, and electron density profiles can be produced by HF heating in the convecting high-latitude F layer.

    Markov, P.


    Simplified relations are presented for shells of revolution and the finite difference energy method is described as is its numerical application to the problems of the mechanics of the shells of revolution of a complex and branched meridian, used in the BOSOR4 program. Also presented are two examples of calculating the free vibration of systems of shells of revolution using the said program. Both problems stemmed from the needs of SKODA, Energeticke Strojirenstvi. The first concerns the free vibration of the system of WWER-440 reactor vessels, approximating its internals. The second concerns the eigenfrequencies and corresponding shapes of the vibrations of the DK3 diagnostic assembly which was designed and manufactured for improved knowledge of events taking place in the reactor core during different operating modes.

    Steen, Aa.


    A ground based technique to monitor the three-dimensional distribution of auroral emissions is presented. The system is composed of two subsystems. A monochromatic imaging system with digitizing capability monitors the two-dimensional variation of auroral intensity with 50 degree field of view. A second height measuring system obtains in real time the height distribution of the auroral luminosity within the field of view of the imaging system. This paper is a report of the stepwise development of the complete system. The measurements will be carried out in the magnetic meridian plane through the EISCAT-site in Norway and the Kiruna Geophysical Institute. The operation of the optical system will as much as possible be combined with incoherent scatter radar measurements. (author)

  6. On solution of Maxwell's equations in axisymmetric domains with edges. Part II: Numerical aspects

    International Nuclear Information System (INIS)

    Nkemzi, Boniface


    In this paper we consider the Fourier-finite-element method for treating the Maxwell's equations in three-dimensional axisymmetric domains with reentrant edges. By means of partial Fourier analysis, the 3D BVP is decomposed into an infinite sequence of 2D variational equations in the plane meridian domain of the axisymmetric domain, a finite number of which is considered and treated using nodal H 1 -conforming finite elements. For domains with reentrant edges, the singular field method is employed to compensate the singular behavior of the solutions. Emphases are given to estimates of the Fourier-finite-element approximation error and convergence analysis in the H 1 -norm under different regularity assumptions. (author)

  7. Maxwell's equations in axisymmetrical geometry: coupling H(curl) finite element in volume and H(div) finite element in surface. The numerical code FuMel

    International Nuclear Information System (INIS)

    Cambon, S.; Lacoste, P.


    We propose a finite element method to solve the axisymmetric scattering problem posed on a regular bounded domain. Here we shall show how to reduce the initial 3D problem into a truncated sum of 2D independent problems posed into a meridian plane of the object. Each of these problem results in the coupling of a partial differential equation into the interior domain and an integral equation on the surface simulating the free space. Then variational volume and boundary integral formulations of Maxwell's equation on regular surfaces are derived. We introduce some general finite element adapted to cylindrical coordinates and constructed from nodal and mixed finite element both for the interior (volume) and for the integral equation (surface).

  8. On the determination of heliographic positions and rotation velocities of sunspots. Pt. 2

    International Nuclear Information System (INIS)

    Balthasar, H.


    Using sunspot positions of small sunspots observed at Debrecen and Locarno as well as positions of recurrent sunspots taken from the Greenwich Photoheliographic Results (1940-1976) the influence of the Wilson depression on the rotation velocities was investigated. It was found that the Wilson depression can be determined by minimizing errors of the rotation velocities or minimizing the differences of rotation velocities determined from disk passages and central meridian passages. The Wilson depressions found were between 765 km and 2500 km for the first sample while they were between 0 km and several 1000 km for the second sample. The averaged Wilson depression for the second sample is between 500 km and 965 km depending on the reduction method. A dependence of the Wilson depression on the age of the spots investigated seems not to exist. (orig.)

  9. The sagitta and lens thickness: the exact solution and a matrix approximation for lenses with toric, spherical, and cylindrical surfaces. (United States)

    Harris, W F


    The exact equation for sagitta of spherical surfaces is generalized to toric surfaces which include spherical and cylindrical surfaces as special cases. Lens thickness, therefore, can be calculated accurately anywhere on a lens even in cases of extreme spherical and cylindrical powers and large diameters. The sagittae of tire- and barrel-form toric surfaces differ off the principal meridians, as is shown by a numerical example. The same holds for pulley- and capstan-form toric surfaces. A general expression is given for thickness at an arbitrary point on a toric lens. Approximate expressions are derived and re-expressed in terms of matrices. The matrix provides an elegant means of generalizing equations for spherical surfaces and lenses to toric surfaces and lenses.

  10. Acupuncture in the treatment of headache: a traditional explanation of an ancient art. (United States)

    Cady, Roger K; Farmer, Kathleen


    Over the past 4000 years, acupuncture has survived the test of time. Recent scientific studies posit acupuncture is an effective intervention for back and joint pain and headache, including migraine. The process of acupuncture is explained, including the role of Qi, the integration of Yang and Yin, the 5 elements, the 8 trigrams, and the metaphors that help the acupuncturist understand the patient, interpret symptoms, and determine acupuncture points in the meridians used to prevent or treat disease. A case study is presented from 3 perspectives: allopathic, traditional acupuncture, and Western acupuncture. Selected acupuncture studies in headache are reviewed. The safety of acupuncture is discussed as well as the challenges in conducting clinical studies of acupuncture. © 2015 American Headache Society.

    Problems of extremely high frequency (EHF) therapy, microwave resonance therapy (MRT) and information-wave therapy (IWT) are considered. Possibilities of electromagnetic waves in millimeter energy range use in clinical and health resort practice are systematized. Recommendations on their use in treatment of different diseases are given. The main principles of selection of zones for meridian correction with the help of electromagnetic waves in millimeter energy range are exposed. The results of EFH-therapy clinical use indicate the possibility of its application practically in all cases, since positive results were obtained in most cases. The recommendations are prepared with account of possibilities and parameters of the apparatus ''MIT-1'' for reflexotherapy which was designed and produced by the Medical Innovative Centre in Kiev

  12. Stability Analysis of Hypersonic Boundary Layer over a Cone at Small Angle of Attack

    Directory of Open Access Journals (Sweden)

    Feng Ji


    Full Text Available An investigation on the stability of hypersonic boundary layer over a cone at small angle of attack has been performed. After obtaining the steady base flow, linear stability theory (LST analysis has been made with local parallel assumption. The growth rates of the first mode and second mode waves at different streamwise locations and different azimuthal angles are obtained. The results show that the boundary layer stability was greatly influenced by small angles of attack. The maximum growth rate of the most unstable wave on the leeward is larger than that on the windward. Moreover, dominating second mode wave starts earlier on the leeward than that on the windward. The LST result also shows that there is a “valley” region around 120°~150° meridian in the maximum growth rates curve.

  13. A Study on the Optimal Duration of Daylight Saving Time (DST in Korea

    Directory of Open Access Journals (Sweden)

    Byeong-Hee Mihn


    Full Text Available Daylight saving time aims at spending effective daylight in summer season. Korea had enforced daylight saving time twelve times from 1948 to 1988. Since 1988, it is not executed, but it is recently discussed the resumption of DST. In this paper, we investigate the trend of DST in other countries, review the history of DST in Korea, and suggest the optimal DST duration in terms of astronomical aspects (times of sunrise and sunset. We find that the starting day of DST in Korea is apt for the second Sunday in Mayor the second Sunday in April according to the time of sunrise or to the difference between Korean standard meridian and observer`s, respectively. We also discuss time friction that might be caused by time difference between DST and Korea Standard Time (KST.

  14. Design and Evaluation on the Mobile Application of Transcutaneous Electrical Nerve Stimulation (TENS). (United States)

    Cheng, Ching-Lung; Lee, Li-Hui; Cheng, Yu-Ting


    This study aims to design a transcutaneous electrical nerve stimulation Application (TENS App) according to the suggestions from potential users. To the best of our knowledge, this is the first App including meridian and acupoints for TENS. After its development, there are eight participants recruited for evaluating the usability. Despite two out of eight users reporting that the typical TENS system requires lower cost and has better functionality than TENS App, the results show that almost seventy percent of participants have a better perception of TENS App on price, functionality, convenience, operational ability, and quality. However, participants still reported concerns about the safety issue of adopting TENS App. Therefore, for people who are the first time or unfamiliar with TENS App, instructions from occupational or physical therapists are recommended. We conclude that by using TENS App, users can not only use the portable electrotherapy devices at anyplace, but also reduce their outpatient visits.

  15. Regiomontanus or learning how to play with science (United States)

    Marian, Anca-Catalina


    Although at the international school competitions, Romanian students are in the top, but few students decide to learn science in school. The major problem is "how to motivate students to study science?" In cooperation with Meridian Zero Astroclub, Oradea, we provide students non-formal space where non-formal activities can approach them to the work of a researcher. Five days in September, ten to fifteen students are invited in a journey through the science world. • Formation of the Moon's craters • Solar radiation • Solar cycles • Constellations • Solar System • Eratosthenes experiment These topics are examples from our activities. Working with students from 4 years old to 18 years old, all activities are developed in the form of games, combining mathematical skills with physics or astronomy. Older students are put in the position of teachers for younger students. Results: A better understanding of physical processes, a higher interest in science, a better application of mathematical concepts in class.

    Full Text Available The article presents results of specialized processing of the deep seismic profile along a part of Reference Profile 3-DV which crosses the Aldan-Stanovoi shield in the meridian direction and goes across its buried northern slope. The study is aimed at determining frequency-energy characteristics of the seismic wave field which are related to physical conditions of geological features of the crust. Based on analysis and interpretation of the dynamic profiles, it is possible to reveal and contour the Archean cores of consolidation of the Aldan shield and its buried continuation that is covered by sediments of the Middle Lena monocline and to input new facts in the proposed geodynamic model showing formation of the crust in the south-eastern segment of the North Asian craton.

  17. James Gregory, the University observatory and the early acquisition of scientific instruments at the University of St Andrews (United States)

    Rawson, Helen C.


    James Gregory, inventor of the reflecting telescope and Fellow of the Royal Society, was the first Regius Professor of Mathematics of the University of St Andrews, 1668–74. He attempted to establish in St Andrews what would, if completed, have been the first purpose-built observatory in the British Isles. He travelled to London in 1673 to purchase instruments for equipping the observatory and improving the teaching and study of natural philosophy and mathematics in the university, seeking the advice of John Flamsteed, later the first Astronomer Royal. This paper considers the observatory initiative and the early acquisition of instruments at the University of St Andrews, with reference to Gregory's correspondence, inventories made ca. 1699–ca. 1718 and extant instruments themselves, some of which predate Gregory's time. It examines the structure and fate of the university observatory, the legacy of Gregory's teaching and endeavours, and the meridian line laid down in 1748 in the University Library.

  18. From elongated spanning trees to vicious random walks (United States)

    Gorsky, A.; Nechaev, S.; Poghosyan, V. S.; Priezzhev, V. B.


    Given a spanning forest on a large square lattice, we consider by combinatorial methods a correlation function of k paths (k is odd) along branches of trees or, equivalently, k loop-erased random walks. Starting and ending points of the paths are grouped such that they form a k-leg watermelon. For large distance r between groups of starting and ending points, the ratio of the number of watermelon configurations to the total number of spanning trees behaves as r-ν log r with ν = (k2 - 1) / 2. Considering the spanning forest stretched along the meridian of this watermelon, we show that the two-dimensional k-leg loop-erased watermelon exponent ν is converting into the scaling exponent for the reunion probability (at a given point) of k (1 + 1)-dimensional vicious walkers, ν˜ =k2 / 2. At the end, we express the conjectures about the possible relation to integrable systems.

    Nishi, Letícia; Bergamasco, Rosângela; Toledo, Max Jean de Ornelas; Falavigna, Dina Lúcia Morais; Gomes, Mônica Lúcia; Mota, Lúcio Tadeu; Falavigna-Guilherme, Ana Lúcia


    The objective of this study was to investigate the occurrence of cysts of Giardia spp. and oocysts of Cryptosporidium spp. in waters of the Ivaí Indigenous Land, Brazil. Samples of river and spring water and of treated water were filtered and analyzed by direct immunofluorescence (Merifluor kit, Meridian Bioscience, Cincinnati, Ohio). Of 21 samples, 7 from each locality, 3 (3/7, 42.8%) from a river were positive for Giardia (mean concentration 2.57 cysts/L), and 1 (1/7, 14.3%) was positive for Cryptosporidium (6 oocysts/L). From springs, 1 sample (1/7, 14.3%) was positive for Cryptosporidium (6 oocysts/L). One sample (1/7, 14.3%) from treated water was positive for both, with 4 oocysts/L and 2 cysts/L. Giardia was the more frequent protozoan present.

  20. Natural-draught cooling towers made of reinforced concrete. State of the art and development possibilities

    Energy Technology Data Exchange (ETDEWEB)

    Kraetzig, W B; Peters, H L; Zerna, W


    Large power plant units and dry cooling tower technology require larger dimensions for natural-draught cooling towers. The main curvation radii in latitudinal and meridian direction are thus increased, which results in a lower three-dimensional support strength. This development is an incentive for constant re-consideration of calculation methods, safety philosophy, and dimensioning criteria. In this context, wind effects have been re-formulated and given a scientific foundation. Constructional measures to improve the static and dynamic behaviour of the structure have been presented and critically assessed. A cost analysis, finally, gave the most rational applications of the new shell construction with reinforcing elements. A cooling tower now under construction gave a realistic example. Fundamental aspects concerning the foundations of cooling tower shells and two special types of foundation are further points to clarify the subject.

  1. [Version and compilation of Harikyuuhousouyou of Vietnamese medical book]. (United States)

    Du, Fengjuan; Xiao, Yongzhi


    Harikyuuhousouyou (《》)was written in 1827 and the author is unknown. The book has only one version which is collected by the National Library of Vietnam. The book contains one volume and includes contraindication of acupuncture and moxibustion, meridian points, point locations, indications and the therapeutic methods at extraordinary points. They are mainly cited from Zhen Jiu Da Quan (《》 Great Compendium on Acupuncture and Moxibustion ) by XU Feng , Yi Xue Ru Men (《》 Elementary Medicine ) by LI Chan and Shou Shi Bao Yuan (《》 Longevity and Health Preservation ) by GONG Tingxian in the Ming Dynasty. In the paper, in view of the characteristics of version and compilation, the hand-coped book was introduced. It was explored that Vietnam acupuncture absorbed Chinese medicine and emphasized clinical practice rather than theoretic statement.

  2. Time and Time Again; Determination of longitude at sea in the 17th Century (United States)

    de Grijs, Richard


    Determination of one's longitude at sea has perplexed sailors for many centuries. The significant uptake of world trade in the 17th and 18th Centuries rendered the increasingly urgent need to solve the 'longitude problem', an issue of strategic national importance. Historical accounts of these efforts often focus almost exclusively on John Harrison's role in 18th-Century Britain. This book starts instead from Galileo Galilei's late-16th-Century development of an accurate pendulum clock, which was first achieved in practice in the mid-17th-Century by Christiaan Huygens in the Dutch Republic. It is primarily based on collections of letters that have not been combined into a single volume before. Extensive introductory chapters on the history of map making, the establishment of the world's reference meridian at Greenwich Observatory, and the rise of the scientific enterprise provide the appropriate context for non-expert readers to fully engage with the book's main subject matter.

  3. Wave propagation to lower hybrid resonance in a magnetic field with shear

    International Nuclear Information System (INIS)

    Ohkubo, Kunizo; Ohasa, Kazumi; Matsuura, Kiyokata


    The ray trajectories of electrostatic wave to the lower hybrid (LH) resonance on the meridian plane of torus is significantly modified as compared with that without shear. The ray starting from the vicinity of the plasma surface rotates spirally around the magnetic axis. The ray reaching the layer S=0, where the perpendicular dielectric constant vanishes, is not terminated but reflected along the second characteristic curve towards another point on the layer S=0. After being reflected successively, rays finally converge on the node point of the layer S=0 on the equatorial plane. In the absence of the layer S=0 the rays infinitely reflect between the cutoff layers near the center and surface of plasma and cover all the region between the layers. (auth.)

  4. Archaic artifacts resembling celestial spheres (United States)

    Dimitrakoudis, S.; Papaspyrou, P.; Petoussis, V.; Moussas, X.

    We present several bronze artifacts from the Archaic Age in Greece (750-480 BC) that resemble celestial spheres or forms of other astronomical significance. They are studied in the context of the Dark Age transition from Mycenaean Age astronomical themes to the philosophical and practical revival of astronomy in the Classical Age with its plethora of astronomical devices. These artifacts, mostly votive in nature are spherical in shape and appear in a variety of forms their most striking characteristic being the depiction of meridians and/or an equator. Most of those artifacts come from Thessaly, and more specifically from the temple of Itonia Athena at Philia, a religious center of pan-Hellenic significance. Celestial spheres, similar in form to the small artifacts presented in this study, could be used to measure latitudes, or estimate the time at a known place, and were thus very useful in navigation.

  5. Low latitude ionosphere-thermosphere dynamics studies with inosonde chain in Southeast Asia

    Directory of Open Access Journals (Sweden)

    T. Maruyama


    Full Text Available An ionosonde network consisting of a meridional chain and an equatorial pair was established in the Southeast Asian area. Three of four ionosondes are along the magnetic meridian of 100° E; two are close to the magnetic conjugate points in Northern Thailand and West Sumatra, Indonesia, and the other is near the magnetic equator in the Malay Peninsula, Thailand. The fourth ionosonde is also near the magnetic equator in Vietnam but separated by about 6.3° towards east from the meridional chain. For a preliminary data analysis, nighttime ionospheric height variations at the three stations of the meridional chain were examined. The results demonstrate that the coordination of the network has a great potential for studying ionosphere/thermosphere dynamics. Through the assistance of model calculations, thermospheric neutral winds were inferred and compared with the HWM93 empirical thermospheric wind model. Higher-order wind variations that are not represented in the empirical model were found.

  6. Characteristics of equatorial ionization anomaly (EIA) in relation to transionospheric satellite links around the northern crest in the Indian longitude sector (United States)

    Das, A.; Paul, K. S.; Halder, S.; Basu, K.; Paul, A.


    The poleward gradient of the equatorial ionization anomaly (EIA) introduces more intense propagation effects on transionospheric satellite links in comparison to the equatorward gradient. Characterization of the poleward gradient was performed during March-April, August-October 2011 and March-April 2012 using GPS total electron content (TEC) recorded from a chain of stations located more or less along the same meridian (88.5° E) at Calcutta, Baharampore, Farakka and Siliguri. The poleward gradients calculated on magnetically quiet days at elevation in excess of 50° at 14:00, 15:00 and 16:00 LT were found to have a strong correlation with GPS S4 observed from Calcutta during post-sunset-to-midnight hours. A threshold value of poleward TEC gradient is calculated above which there is a probability of scintillation at Calcutta with S4 ≥ 0.4.

  8. Large scale circulation in the convection zone and solar differential rotation

    Energy Technology Data Exchange (ETDEWEB)

    Belvedere, G [Instituto di Astronomia dell' Universita di Catania, 95125 Italy; Paterno, L [Osservatorio Astrofisico di Catania, 95125 Italy


    In this paper the dependence on depth and latitude of the solar angular velocity produced by a meridian circulation in the convection zone is studied assuming that the main mechanism responsible for setting up and driving the circulation is the interaction of rotation with convection. The first order equations (perturbation of the spherically symmetric state are solved in the Boussinesq approximation and in the steady state for the axissymmetric case. The interaction of convection with rotation is modelled by a convective transport coefficient. The model is consistent with the fact that the interaction of convection with rotation sets up a circulation (driven by the temperature gradient) which carries angular momentum toward the equator against the viscous friction. Unfortunately also a large flux variation at the surface is obtained. Nevertheless it seems that the model has the basic requisites for correct dynamo action.

  9. Armagh Observatory - Historic Building Information Modelling for Virtual Learning in Building Conservation (United States)

    Murphy, M.; Chenaux, A.; Keenaghan, G.; GIbson, V..; Butler, J.; Pybusr, C.


    In this paper the recording and design for a Virtual Reality Immersive Model of Armagh Observatory is presented, which will replicate the historic buildings and landscape with distant meridian markers and position of its principal historic instruments within a model of the night sky showing the position of bright stars. The virtual reality model can be used for educational purposes allowing the instruments within the historic building model to be manipulated within 3D space to demonstrate how the position measurements of stars were made in the 18th century. A description is given of current student and researchers activities concerning on-site recording and surveying and the virtual modelling of the buildings and landscape. This is followed by a design for a Virtual Reality Immersive Model of Armagh Observatory use game engine and virtual learning platforms and concepts.

  10. [Reflexology--nothing in common with scientific naturopathic treatments]. (United States)

    Heide, M; Heide, M H


    A host of alternative treatment methods are sold to us as reputable science on the "supermarket of naturopathy" nowadays. "Foot zone therapy", also known as "reflexology" is one of them. Advocates of reflexology claim that certain zones of the feet are linked to internal organs; that "energy forces" run throughout the human body. According to the teachings of Ayurveda and Yoga, a network of more than 72,000 nerve tracts (energy tracts = meridians) is linked to a single, tiny point on the feet, where the energy ends. In reality, however, reflexology is an unconventional, alternative, paramedical and esoterical "outsider" method that has nothing in common with serious naturopathic treatments. Any scientific value to reflexology is to be denied. As opposed to reflexology, genuine, scientifically acknowledged naturopathic methods are not an alternative, but a supplement to modern medicine.

  11. [Surgical solutions to luxation of the IOL--capsular bag--capsular tension ring complex]. (United States)

    Berthout, A; Turut, P; Taboureau, E; Denimal, F; Milazzo, S


    The spontaneous luxation of the intraocular lens-capsular bag-capsular tension ring complex is a serious but fortunately rare complication. The authors report a combined surgical procedure to reposition the complex in a patient who was operated on for bilateral lens subluxation 4 years before and whose enophthalmia made surgery difficult. Two surgical techniques can be considered to reposition the complex and avoid explantation. The McCannel modified stitch can capture the complex with the help of a transcorneal point and then a transscleral suture on the 12 o'clock meridian, despite the enophthalmia of the patient; the Moreno transscleral stitch. Both techniques suture the complex to the ciliary sulcus. Moreno's technique is easy and safe for the endothelium and must therefore be attempted first. In case of failure, the McCannel modified stitch remains a useful and satisfying procedure allowing transscleral fixation of the complex to the sulcus at the cost of a minimal corneal trauma.

  12. The rotational elements of Mars and its satellites (United States)

    Jacobson, R. A.; Konopliv, A. S.; Park, R. S.; Folkner, W. M.


    The International Astronomical Union (IAU) defines planet and satellite coordinate systems relative to their axis of rotation and the angle about that axis. The rotational elements of the bodies are the right ascension and declination of the rotation axis in the International Celestial Reference Frame and the rotation angle, W, measured easterly along the body's equator. The IAU specifies the location of the body's prime meridian by providing a value for W at epoch J2000. We provide new trigonometric series representations of the rotational elements of Mars and its satellites, Phobos and Deimos. The series for Mars are from a least squares fit to the rotation model used to orient the Martian gravity field. The series for the satellites are from a least squares fit to rotation models developed in accordance with IAU conventions from recent ephemerides.

  13. Vibrations of laminated composite thick shells of revolution having meridionally varying curvature

    International Nuclear Information System (INIS)

    Suzuki, Katsuyoshi; Shikanai, Genji; Baba, Iwato


    An exact solution is presented for solving free vibrations of laminated composite thick shells of revolution having meridionally varying curvature. Based on the thick lamination theory considering the shear deformation and rotary inertia, equations of motion and boundary conditions are obtained from the stationary conditions of the Lagrangian. The equations of motion are solved exactly by using a power series expansion for symmetrically laminated cross-ply shells. Frequencies and mode shapes of shells of revolution having elliptical and parabolical meridians are presented for both ends clamped, and the effects of shear deformation and rotary inertia are discussed by comparing the results from the present theory with those from the thin lamination theory.

  14. Numerical simulation of liquid film flow on revolution surfaces with momentum integral method

    International Nuclear Information System (INIS)

    Bottoni Maurizio


    The momentum integral method is applied in the frame of safety analysis of pressure water reactors under hypothetical loss of coolant accident (LOCA) conditions to simulate numerically film condensation, rewetting and vaporization on the inner surface of pressure water reactor containment. From the conservation equations of mass and momentum of a liquid film arising from condensation of steam upon the inner of the containment during a LOCA in a pressure water reactor plant, an integro-differential equation is derived, referring to an arbitrary axisymmetric surface of revolution. This equation describes the velocity distribution of the liquid film along a meridian of a surface of revolution. From the integro-differential equation and ordinary differential equation of first order for the film velocity is derived and integrated numerically. From the velocity distribution the film thickness distribution is obtained. The solution of the enthalpy equation for the liquid film yields the temperature distribution on the inner surface of the containment. (authors)

  15. From elongated spanning trees to vicious random walks

    International Nuclear Information System (INIS)

    Gorsky, A.; Nechaev, S.; Poghosyan, V.S.; Priezzhev, V.B.


    Given a spanning forest on a large square lattice, we consider by combinatorial methods a correlation function of k paths (k is odd) along branches of trees or, equivalently, k loop-erased random walks. Starting and ending points of the paths are grouped such that they form a k-leg watermelon. For large distance r between groups of starting and ending points, the ratio of the number of watermelon configurations to the total number of spanning trees behaves as r −ν logr with ν=(k 2 −1)/2. Considering the spanning forest stretched along the meridian of this watermelon, we show that the two-dimensional k-leg loop-erased watermelon exponent ν is converting into the scaling exponent for the reunion probability (at a given point) of k(1+1)-dimensional vicious walkers, ν -tilde= k 2 /2. At the end, we express the conjectures about the possible relation to integrable systems

  16. On the structure of the tail magnetic field

    International Nuclear Information System (INIS)

    Candidi, M.; Orsini, S.; Stokholm, M.; Elphic, R.C.


    The authors present a study comparing the magnetic field configuration in the magnetotail lobes with that in the plasma sheet boundary layer. The results indicate a systematic enhancement of the By component of the plasma sheet boundary layer field over that of the lobe. The value of such enhancement increases with distance from the midnight meridian plane and has the same sense in the northern and southern plasma sheet boundary layer. Such a By enhancement corresponds to a smaller rate of flaring of the magnetic field lines in the lobe with respect to the plasma sheet boundary layer. This observation is interpreted as a signature of field-aligned currents at the boundary. The direction of the field-aligned currents agrees with the nightside region 1 current system, which is the most poleward system in the nightside polar ionosphere at low altitude

  17. Vernal Point and Anthropocene (United States)

    Chavez-Campos, Teodosio; Chavez S, Nadia; Chavez-Sumarriva, Israel


    The time scale was based on the internationally recognized formal chronostratigraphical /geochronological subdivisions of time: The Phanerozoic Eonathem/Eon; the Cenozoic Erathem/Era; the Quaternary System/Period; the Pleistocene and Holocene Series/Epoch. The Quaternary was divided into: (1) The Pleistocene that was characterized by cycles of glaciations (intervals between 40,000 and 100,000 years). (2) The Holocene that was an interglacial period that began about 12,000 years ago. It was believed that the Milankovitch cycles (eccentricity, axial tilt and the precession of the equinoxes) were responsible for the glacial and interglacial Holocene periods. The magnetostratigraphic units have been widely used for global correlations valid for Quaternary. The gravitational influence of the sun and moon on the equatorial bulges of the mantle of the rotating earth causes the precession of the earth. The retrograde motion of the vernal point through the zodiacal band is 26,000 years. The Vernal point passes through each constellation in an average of 2000 years and this period of time was correlated to Bond events that were North Atlantic climate fluctuations occurring every ≡1,470 ± 500 years throughout the Holocene. The vernal point retrogrades one precessional degree approximately in 72 years (Gleissberg-cycle) and approximately enters into the Aquarius constellation on March 20, 1940. On earth this entry was verify through: a) stability of the magnetic equator in the south central zone of Peru and in the north zone of Bolivia, b) the greater intensity of equatorial electrojet (EEJ) in Peru and Bolivia since 1940. With the completion of the Holocene and the beginning of the Anthropocene (widely popularized by Paul Crutzen) it was proposed the date of March 20, 1940 as the beginning of the Anthropocene. The date proposed was correlated to the work presented in IUGG (Italy 2007) with the title "Cusco base meridian for the study of geophysical data"; Cusco was

  18. Hydraulic performance of a low specific speed centrifugal pump with Spanwise-Slotted Blades

    International Nuclear Information System (INIS)

    Ye, D X; Li, H; Wang, Y


    The hydraulic efficiency of a low specific speed centrifugal pump is low because of the long and narrow meridian flow passage, and the severe disk friction. Spanwise slotted blade flow control technology has been applied to the low specific speed centrifugal pump. This paper concluded that spanwise slotted blades can improve the pump performance in both experiments and simulations. In order to study the influence to the impeller and volute by spanwise slotted blade, impeller efficiency and volute efficiency were defined. The minimum volute efficiency and the maximum pump efficiency appear at the same time in the design flow condition in the unsteady simulation. The mechanism of spanwise slotted blade flow control technology should be researched furthermore

    Full Text Available Our experimental studies and a set of the published data allow one to conclude that animals and humans can perceive visible light not only with mediation of the visual sensory system, but also due to the existence of specific extraocular photoreceptors. In the latter system, we can classify three separate stable levels of interaction with exogeneous electromagnetic waves (EMW of the visible range. The first, most simple level is the cellular level (cells possessing sensor proteins reactable to EMW. The next, higher level is based on interaction of EVW with specialized electromagnetoreceptors; acupuncture points and meridians providing the maintenance of electromagnetic homeostasis of the organism cam be considered such a receptor system. Finally, the most complex level involves specialized sensory pathways and central brain structures controlling general homeostasis of the organism with mediation of the processes of metabolism.

    Kraetzig, W.B.; Peters, H.L.; Zerna, W.


    Large power plant units and dry cooling tower technology require larger dimensions for natural-draught cooling towers. The main curvation radii in latitudinal and meridian direction are thus increased, which results in a lower three-dimensional support strength. This development is an incentive for constant re-consideration of calculation methods, safety philosophy, and dimensioning criteria. In this context, wind effects have been re-formulated and given a scientific foundation. Constructional measures to improve the static and dynamic behaviour of the structure have been presented and critically assessed. A cost analysis, finally, gave the most rational applications of the new shell construction with reinforcing elements. A cooling tower now under construction gave a realistic example. Fundamental aspects concerning the foundations of cooling tower shells and two special types of foundation are further points to clarify the subject. (orig./HP) [de

    Huang, C.S.; Murr, D.; Sofko, G.J.


    response to IMF Bz changes during strong IMF BZ. On March 23, 1995, B-x was small, B-y was strongly positive (7-11 nT), and the B-z polarity changed several times after 1300 UT. The dayside ionospheric convection is dominated by a large clockwise convection cell. The cell focus (the "eye" of the convection...... cell, or the largest change in the convection pattern, is limited roughly to the region between the previous cell focus and the new cell focus. Outside this region, the ionospheric flows could be greatly enhanced or weakened, while the convection pattern shape changes very little. When B-y is strong...... the dawn-dusk meridian plane, which is interpreted as propagation or expansion of newly generated convection cells in the cusp region. Other studies showed that the change in convection pattern in response to IMF reorientations is spatially fixed. In this paper, we investigate the ionospheric convection...

    Morris, Brett M.; Tollerud, Erik; Sipőcz, Brigitta; Deil, Christoph; Douglas, Stephanie T.; Berlanga Medina, Jazmin; Vyhmeister, Karl; Smith, Toby R.; Littlefair, Stuart; Price-Whelan, Adrian M.; Gee, Wilfred T.; Jeschke, Eric


    We present astroplan—an open source, open development, Astropy affiliated package for ground-based observation planning and scheduling in Python. astroplan is designed to provide efficient access to common observational quantities such as celestial rise, set, and meridian transit times and simple transformations from sky coordinates to altitude-azimuth coordinates without requiring a detailed understanding of astropy’s implementation of coordinate systems. astroplan provides convenience functions to generate common observational plots such as airmass and parallactic angle as a function of time, along with basic sky (finder) charts. Users can determine whether or not a target is observable given a variety of observing constraints, such as airmass limits, time ranges, Moon illumination/separation ranges, and more. A selection of observation schedulers are included that divide observing time among a list of targets, given observing constraints on those targets. Contributions to the source code from the community are welcome.

    Full Text Available Purpose: To develop an uniform method of the treatment for patients with progressive keratoconus (stage 1‑2 and cataract. Patients and methods: 4 patients (5 eyes with cataract and progressive keratoconus stage 1‑2 were enrolled in the study. Mean age was 42 years. In all patients, standard ophthalmic examination as well corneal topography, anterior segment optical coherence tomography, biometry, and IOL power calculations using IOLMaster were performed. Mean uncorrected visual acuity (UCVA was 0.1 while mean best-corrected visual acuity (BCVA was 0.4. Surgical technique included two steps. The first step was the creation of corneal tunnels with femtosecond laser with subsequent phaco and monofocal aspheric IOL implantation. The second step (1‑2 weeks later was the implantation of intrastromal ring segments based on corneal topography and corneal crosslinking.Results: After the first step, all patients had myopic refraction (from –1.0 D to –2.5 D. Cylindrical component was almost unchanged. After the second step, the patients reported the vision improvement, mainly due to UCVA. Both spherical (myopic and cylindrical components decreased, mainly due to the steep meridian. After the treatment, optical power of the cornea decreased, mainly due to the steep meridian. UCVA was 0.6 or more in 60 % of cases, final BCVA was 0.8‑1.0 in 80 % of cases. Neither intraoperative nor postoperative (follow-up was 2 years complications were observed.Conclusions: Combined phaco and prior creation of corneal tunnels with subsequent intrastromal ring segment implantation and crosslinking in patients with cataract and progressive keratoconus stage 1‑2 is safe, provides good predictable outcome and significantly reduces rehabilitation period.

  5. Acupuncture induces divergent alterations of functional connectivity within conventional frequency bands: evidence from MEG recordings.

    Youbo You

    Full Text Available As an ancient Chinese healing modality which has gained increasing popularity in modern society, acupuncture involves stimulation with fine needles inserted into acupoints. Both traditional literature and clinical data indicated that modulation effects largely depend on specific designated acupoints. However, scientific representations of acupoint specificity remain controversial. In the present study, considering the new findings on the sustained effects of acupuncture and its time-varied temporal characteristics, we employed an electrophysiological imaging modality namely magnetoencephalography with a temporal resolution on the order of milliseconds. Taken into account the differential band-limited signal modulations induced by acupuncture, we sought to explore whether or not stimulation at Stomach Meridian 36 (ST36 and a nearby non-meridian point (NAP would evoke divergent functional connectivity alterations within delta, theta, alpha, beta and gamma bands. Whole-head scanning was performed on 28 healthy participants during an eyes-closed no-task condition both preceding and following acupuncture. Data analysis involved calculation of band-limited power (BLP followed by pair-wise BLP correlations. Further averaging was conducted to obtain local and remote connectivity. Statistical analyses revealed the increased connection degree of the left temporal cortex within delta (0.5-4 Hz, beta (13-30 Hz and gamma (30-48 Hz bands following verum acupuncture. Moreover, we not only validated the closer linkage of the left temporal cortex with the prefrontal and frontal cortices, but further pinpointed that such patterns were more extensively distributed in the ST36 group in the delta and beta bands compared to the restriction only to the delta band for NAP. Psychophysical results for significant pain threshold elevation further confirmed the analgesic effect of acupuncture at ST36. In conclusion, our findings may provide a new perspective to lend

    Schillaci, Alessandro; D'Alessandro, Giuseppe; de Bernardis, Paolo; Masi, Silvia; Paiva Novaes, Camila; Gervasi, Massimo; Zannoni, Mario


    Context. Precision measurements of the Sunyaev-Zel'dovich effect in clusters of galaxies require excellent rejection of common-mode signals and wide frequency coverage. Aims: We describe an imaging, efficient, differential Fourier transform spectrometer (FTS), optimized for measurements of faint brightness gradients at millimeter wavelengths. Methods: Our instrument is based on a Martin-Puplett interferometer (MPI) configuration. We combined two MPIs working synchronously to use the whole input power. In our implementation the observed sky field is divided into two halves along the meridian, and each half-field corresponds to one of the two input ports of the MPI. In this way, each detector in the FTS focal planes measures the difference in brightness between two sky pixels, symmetrically located with respect to the meridian. Exploiting the high common-mode rejection of the MPI, we can measure low sky brightness gradients over a high isotropic background. Results: The instrument works in the range ~1-20 cm-1 (30-600 GHz), has a maximum spectral resolution 1 / (2 OPD) = 0.063 cm-1 (1.9 GHz), and an unvignetted throughput of 2.3 cm2sr. It occupies a volume of 0.7 × 0.7 × 0.33 m3 and has a weight of 70 kg. This design can be implemented as a cryogenic unit to be used in space, as well as a room-temperature unit working at the focus of suborbital and ground-based mm-wave telescopes. The first in-flight test of the instrument is with the OLIMPO experiment on a stratospheric balloon; a larger implementation is being prepared for the Sardinia radio telescope.

  7. Signatures of storm sudden commencements in geomagnetic H, Y and Z fields at Indian observatories during 1958−1992

    Directory of Open Access Journals (Sweden)

    R. G. Rastogi


    Full Text Available The work describes an intensive study of storm sudden commencement (SSC impulses in horizontal (H, eastward (Y and vertical (Z fields at four Indian geomagnetic observatories between 1958–1992. The midday maximum of ΔH has been shown to exist even at the low-latitude station Alibag which is outside the equatorial electrojet belt, suggesting that SSC is associated with an eastward electric field at equatorial and low latitudes. The impulses in Y field are shown to be linearly and inversely related to ΔH at Annamalainagar and Alibag. The average SC disturbance vector is shown to be about 10–20°W of the geomagnetic meridian. The local time variation of the angle is more westerly during dusk hours in summer and around dawn in the winter months. This clearly suggests an effect of the orientation of shock front plane of the solar plasma with respect to the geomagnetic meridian. The ΔZ at SSC have a positive impulse as in ΔH. The ratio of ΔZ/ΔH are abnormally large exceeding 1.0 in most of the cases at Trivandrum. The latitudinal variation of ΔZ shows a tendency towards a minimum over the equator during the nighttime hours. These effects are explained as (1 resulting from the electromagnetic induction effects due to the equatorial electrojet current in the subsurface conducting layers between India and Sri Lanka, due to channelling of ocean currents through the Palk Strait and (2 due to the concentration of induced currents over extended latitude zones towards the conducting graben between India and Sri Lanka just south of Trivandrum.Key words.

  8. [Professor LAI Xinsheng's clinical experience in the treatment of premature ovarian failure with tongyuan acupuncture technique and Chinese herbal medicine]. (United States)

    Li, Xiaozhe; Zhang, Sujuan


    In the treatment of premature ovarian failure (POF), professor LAI Xinsheng focuses on the determination of syndrome to seek for etiology, associating with the differentiation of meridian and collateral and that of zangfu organs. Professor LAI believes that POF is mainly manifested as amenorrhea and infertility, localized in the kidney, with the dysfunction of liver, spleen and heart. It is impacted by many pathological factors, such as cold blockage, qi stagnation, blood stagnation, blood deficiency, yin deficiency, etc., which leads to the damage of the thoroughfare vessel and the conception vessel and the blockage of menstrual flow. On the basis of four diagnostic Methods and syndrome differentiation, there are four common syndromes of POF, named qi and blood deficiency, qi and blood stagnation, liver and kidney deficiency and yang deficiency of spleen and kidney. Tongyuan acupuncture technique is summarized by Professor LAI Xinsheng on the basis of yinyang theory. It is an effective and scientific method for acupoint selection along the meridians. The acupoints on the back, communicating with the governor vessel and mind regulation, acting on the brain are selected to promote yang qi of the governor vessel. The back- shu points of five zang organs are selected to regulate the functions of internal organs. The acupoints on the abdomen and the conception vessel are selected to conduce qi to the primary so as to improve reproductive function. In the guidance of tongyuan acupuncture technique, the acupoint prescription is formed and the Chinese herbal medicines are selected in combination to improve ovarian function and regulate menstruation. Hence, the satisfactory therapeutic effects have been achieved.

    To determine the distribution of keratometry and its determinants in Iranian school children. The present cross-sectional study was conducted in 2015 in Shahroud in the north of Iran. The entire rural population of elementary school children was invited to the study. In urban areas, cluster sampling was conducted. Pentacam HR (Oculus Inc., Lynnwood, WA) was used to measure the flat meridian, the steep meridian, and the mean keratometry. Linear regression was used to determine the associated variables with mean keratometry. Of 5620 participated in the study, 5559 children were analyzed after applying the exclusion criteria. Mean keratometry was 43.56 ± 1.96 diopters (D) (95% confidence interval = 43.48-43.64) in the total sample, 43.18 ± 2.23 D (95% confidence interval = 43.09-43.26) in boys, and 44.01 ± 1.46 D (95% confidence interval = 43.95-44.07) in girls (p < 0.001). The highest and lowest mean keratometry was 43.28 ± 1.66 D (95% confidence interval = 43.00-43.55) and 42.89 ±2.70 D (95% confidence interval = 42.68-43.11) in 6-year-old and 10-year-old children, respectively (p = 0.031). The results of multiple linear regression showed that mean keratometry in girls was 0.82 D higher than in boys (p < 0.001), and in groups older than 9 years, it was significantly decreased. Mean keratometry in myopic children was 0.62 D higher than emmetropic children (p < 0.001). This study provided valuable findings from the status of keratometry in Iranian children. In line with other studies, corneal power was higher in girls than in boys, and the cornea becomes flatter with age in children.

  10. Assessment and statistics of surgically induced astigmatism. (United States)

    Naeser, Kristian


    The aim of the thesis was to develop methods for assessment of surgically induced astigmatism (SIA) in individual eyes, and in groups of eyes. The thesis is based on 12 peer-reviewed publications, published over a period of 16 years. In these publications older and contemporary literature was reviewed(1). A new method (the polar system) for analysis of SIA was developed. Multivariate statistical analysis of refractive data was described(2-4). Clinical validation studies were performed. The description of a cylinder surface with polar values and differential geometry was compared. The main results were: refractive data in the form of sphere, cylinder and axis may define an individual patient or data set, but are unsuited for mathematical and statistical analyses(1). The polar value system converts net astigmatisms to orthonormal components in dioptric space. A polar value is the difference in meridional power between two orthogonal meridians(5,6). Any pair of polar values, separated by an arch of 45 degrees, characterizes a net astigmatism completely(7). The two polar values represent the net curvital and net torsional power over the chosen meridian(8). The spherical component is described by the spherical equivalent power. Several clinical studies demonstrated the efficiency of multivariate statistical analysis of refractive data(4,9-11). Polar values and formal differential geometry describe astigmatic surfaces with similar concepts and mathematical functions(8). Other contemporary methods, such as Long's power matrix, Holladay's and Alpins' methods, Zernike(12) and Fourier analyses(8), are correlated to the polar value system. In conclusion, analysis of SIA should be performed with polar values or other contemporary component systems. The study was supported by Statens Sundhedsvidenskabeligt Forskningsråd, Cykelhandler P.

  11. Parametric fitting of corneal height data to a biconic surface. (United States)

    Janunts, Edgar; Kannengießer, Marc; Langenbucher, Achim


    As the average corneal shape can effectively be approximated by a conic section, a determination of the corneal shape by biconic parameters is desired. The purpose of the paper is to introduce a straightforward mathematical approach for extracting clinically relevant parameters of corneal surface, such as radii of curvature and conic constants for principle meridians and astigmatism. A general description for modeling the ocular surfaces in a biconic form is given, based on which an implicit parametric surface fitting algorithm is introduced. The solution of the biconic fitting is obtained by a two sequential least squares optimization approach with constrains. The data input can be raw information from any corneal topographer with not necessarily a uniform data distribution. Various simulated and clinical data are studied including surfaces with rotationally symmetric and non-symmetric geometries. The clinical data was obtained from the Pentacam (Oculus) for the patient having undergone a refractive surgery. A sub-micrometer fitting accuracy was obtained for all simulated surfaces: 0,08 μm RMS fitting error at max for rotationally symmetric and 0,125 μm for non-symmetric surfaces. The astigmatism was recovered in a sub-minutes resolution. The equality in rotational symmetric and the superiority in non-symmetric surfaces of the presented model over the widely used quadric fitting model is shown. The introduced biconic surface fitting algorithm is able to recover the apical radii of curvature and conic constants in principle meridians. This methodology could be a platform for advanced IOL calculations and enhanced contact lens fitting. Copyright © 2014. Published by Elsevier GmbH.

  12. Understanding the Longitudinal Variability of Equatorial Electrodynamics using integrated Ground- and Space-based Observations (United States)

    Yizengaw, E.; Moldwin, M.; Zesta, E.


    The currently funded African Meridian B-Field Education and Research (AMBER) magnetometer array comprises more than thirteen magnetometers stationed globally in the vicinity of geomagnetic equator. One of the main objectives of AMBER network is to understand the longitudinal variability of equatorial electrodynamics as function of local time, magnetic activity, and season. While providing complete meridian observation in the region and filling the largest land-based gap in global magnetometer coverage, the AMBER array addresses two fundamental areas of space physics: first, the processes governing electrodynamics of the equatorial ionosphere as a function of latitude (or L-shell), local time, longitude, magnetic activity, and season, and second, ULF pulsation strength at low/mid-latitude regions and its connection with equatorial electrojet and density fluctuation. The global AMBER network can also be used to augment observations from space-based instruments, such us the triplet SWARM mission and the upcoming ICON missions. Thus, in coordination with space-based and other ground-based observations, the AMBER magnetometer network provides a great opportunity to understand the electrodynamics that governs equatorial ionosphere motions. In this paper we present the longitudinal variability of the equatorial electrodynamics using the combination of instruments onboard SWARM and C/NOFS satellites and ground-based AMBER network. Both ground- and pace-based observations show stronger dayside and evening sector equatorial electrodynamics in the American and Asian sectors compared to the African sector. On the other hand, the African sector is home to stronger and year-round ionospheric bubbles/irregularities compared to the American and Asian sectors. This raises the question if the evening sector equatorial electrodynamics (vertical drift), which is believed to be the main cause for the enhancement of Rayleigh-Taylor (RT) instability growth rate, is stronger in the

  13. Plasma drifts associated with a system of sun-aligned arcs in the polar cap

    International Nuclear Information System (INIS)

    Mende, S.B.; Doolittle, J.H.; Robinson, R.M.; Vondrak, R.R.; Rich, F.J.


    A series of four sun-aligned arcs passed over Sondre Stromfjord, Greenland, on the night of the 17th and 18th of February, 1985. Observations of these arcs were made using the Sondrestrom incoherent scatter radar and an intensified all-sky imaging TV system that was operated at the radar site. The first of the four arcs crossed the Sondre Stromfjord meridian just before local midnight moving westward, and the other three arcs followed at approximately half-hour intervals. When we account for the earth's rotation, the arc drift in an inertial frame was eastward, or dusk to dawn. The half-hour interval between meridian crossings of the arcs implies that the mean spacing between the arcs was 180 km. A Defense Meteorological Satellite Program (DMSP) F6 satellite pass at 0110 UT revealed the presence of highly structured electron and ion precipitation throughout the polar cap. The DMSP visible imager detected a single, sun-aligned arc associated with the largest peak in precipitating electron flux. This arc was also observed at Thule, Greenland, with an intensified film camera. These observations suggest that at least one of the arcs that were observed at Sondre Stromfjord extended across a large part of the polar cap. The radar at Sondre Stromfjord measured electron density and ion drift velocities associated with the four arcs. The radar drift measurements were superimposed on the all-sky video images to determine the location of the measurements relative to the arcs. Plasma drifts outside the arcs were found to be both sunward and antisunward, while within the arcs the drifts were predominantly antisunward. The variability of the drifts in the direction parallel to the arcs indicates that the electric fields were highly structured even though the configuration and motion of the arcs were well behaved

  14. Comparative study of long-term outcomes of accelerated and conventional collagen crosslinking for progressive keratoconus. (United States)

    Males, J J; Viswanathan, D


    PurposeTo compare the long-term outcomes of accelerated corneal collagen crosslinking (CXL) to conventional CXL for progressive keratoconus.Patients and methodsComparative clinical study of consecutive progressive keratoconic eyes that underwent either accelerated CXL (9 mW/cm 2 ultraviolet A (UVA) light irradiance for 10 min) or conventional CXL (3 mW/cm 2 UVA light irradiance for 30 min). Eyes with minimum 12 months' follow-up were included. Post-procedure changes in keratometry readings (Flat meridian: K1; steep meridian: K2), central corneal thickness (CCT), best spectacle-corrected visual acuity (BSCVA), and manifest refraction spherical equivalent (MRSE) were analysed.ResultsA total of 42 eyes were included. In all, 21 eyes had accelerated CXL (20.5±5.5 months' follow-up) and 21 eyes had conventional CXL group (20.2±5.6 months' follow-up). In the accelerated CXL group, a significant reduction in K2 (P=0.02), however no significant change in K1 (P=0.35) and CCT (P=0.62) was noted. In the conventional CXL group, a significant reduction was seen in K1 (P=0.01) and K2 (P=0.04), but not in CCT (P=0.95). Although both groups exhibited significant reductions in K2 readings, no noteworthy differences were noted between them (P=0.36). Improvements in BSCVA (accelerated CXL; P=0.22 and conventional CXL; P=0.20) and MRSE (accelerated CXL; P=0.97 and conventional CXL; P=0.54) were noted, however were not significant in either group.ConclusionAccelerated and conventional CXL appear to be effective procedures for stabilising progressive keratoconus in the long-term.

  15. Self-excited multi-scale skin vibrations probed by optical tracking micro-motions of tracers on arms (United States)

    Chen, Wei-Chia; Chen, Hsiang-Ying; Chen, Yu-Sheng; Tian, Yong; I, Lin


    The self-excited multi-scale mechanical vibrations, their sources and their mutual coupling of different regions on the forearms of supine subjects, are experimentally investigated, using a simple noncontact method, optical video microscopy, which provides 1 μm and 25 ms spatiotemporal resolutions. It is found that, in proximal regions far from the radial artery, the vibrations are the global vibrations of the entire forearm excited by remote sources, propagating through the trunk and the limb. The spectrum is mainly composed of peaks of very low frequency motion (down to 0.05 Hz), low frequency respiration modes, and heartbeat induced modes (about 1 Hz and its harmonics), standing out of the spectrum floor exhibiting power law decay. The nonlinear mode-mode coupling leads to the cascaded modulations of higher frequency modes by lower frequency modes. The nearly identical waveforms without detectable phase delays for a pair of signals along or transverse to the meridian of regions far away from the artery rule out the detectable contribution from the propagation of Qi, some kind of collective excitation which more efficiently propagates along meridians, according to the Chinese medicine theory. Around the radial artery, in addition to the global vibration, the local vibration spectrum shows very slow breathing type vibration around 0.05 Hz, and the artery pulsation induced fundamental and higher harmonics with descending intensities up to the fifth harmonics, standing out of a flat spectrum floor. All the artery pulsation modes are also modulated by respiration and the very slow vibration.

    Karrouk, Mohammed-Said


    "New Climate" subjected to North Africa, Western Mediterranean and geoclimatic midlatitude space atmospheric effects of the new regime characterized by the supremacy of the meridian circulation (MAC: Meridian Atmospheric Circulation), by alternating cool conditions (humidity) heat (drought) along the year, and imposes situation of anxiety and perplexity vis-a-vis their socio-economic activities; shoved agricultural calendar, hesitant policymakers, uncertainty and waiting, ... etc. The recent example of the fall-winter 2015-2016 is indicative of the conditions that have left a deep psychological imprint on economic and social Moroccans. During this period, the summer heat has extended to the end of autumn and even winter. And precipitation contracted by more than 51% of accumulated rainfall autumn, compared with the same period a normal year. A slowdown in economic growth has been felt since last December and was extended until the rains return (and snow!) In mid February 2016. Weather conditions during this period were marked by the succession and persistence of very active planetary peaks, projected to the northern borders of Western Europe (Heat Christmas 2015!), Rejecting the negative waves to the east: Algeria, Tunisia, Italy, the Balkans, Anatolia, and even the Middle East. These conditions are the consequences of the "New Climate" warmed, strengthened by the strong El Niño event in 2015 decennial. The identification of hemispheric and regional climate mechanisms of these atmospheric regime systems based on energy balance and atmospheric circulation will be defined, with links of cause and effect, in view of integrating these characters to extreme events in the New Climate Warmed.

    Sun, Zhi-Xin; Zhang, Pan-Pan; Gao, Wu-Lin; Dai, Guo-Hua


    To analyze the prescription and medication rules of Chinese medicines in the treatment of palpitations in the Chinese journal full text database(CNKI) by using traditional Chinese medicine inheritance system, and provide a reference for further research and development of modern traditional Chinese medicines(TCMs) in treatment of palpitations. In order to give better guidance for clinical mediation, prescriptions used for treatment of palpitations in CNKI were collected, and then were input to the TCM inheritance support system for establishing a Chinese medicine prescription database for palpitations. The software's revised mutual information, complex system entropy clustering and other data mining methods were adopted to analyze the prescriptions according to the frequencies of herbs, "four natures", "five flavors" and "meridians" of the high-frequency medicines in the database, identify the core herbs and application characteristics, and analyze the prescription rules and medication experience. Totally, 545 prescriptions used for palpitation were included in this study and involved 247 Chinese herbs. The analysis results showed that the herbs in prescriptions for palpitation mostly had the warm property, and the herbs in heart and spleen meridian accounted for a larger proportion, indicating that the treatment was mainly to nourish heart and strengthen spleen. The top 11 herbs in usage frequency were consistent with the high-frequency medicines in medication patterns of common herbal pairs; therefore, we considered that these 11 herbs were the core herbs; the core herbal combination included Cassia Twig, Licorice, fossil fragments, Ostreae decoction, and evolved into 9 new prescriptions for treating palpitation. Our results objectively presented the prescription and medication rules for treating palpitation and provided extremely effective guidance for the clinical therapy.

    To observe and compare the effects of electroacupuncture (EA) at "Tianshu" (ST 25) and "Neiguan" (PC 6) for colonic motility and the expression of colon dopamine D 2 in irritable bowel syndrome (IBS) rats, and to explore the specificity of different meridians and different acupoints. Forty Wistar newborn rats were randomly divided into blank, model, Tianshu and Neiguan groups. Separation of mother and child and acetic acid coloclyster combined with colorectal distension were used to establish IBS model in the model, Tianshu and Neiguan groups. At the age of 9 weeks, EA at bilateral ST 25 and PC 6 were applied in the corresponding groups 5 times, once every other day. After the intervention, the Bristol fecal score, the latent period of abdominal retraction reflex and the number of contraction waves were recorded. The expression of dopamine D 2 receptor was detected by immunohistochemistry. Compared with the blank group, the Bristol fecal score of the model group was higher ( P <0.01), the 1 st contraction wave latent period was shorter ( P <0.01), the number of contraction waves in 90 s increased ( P <0.01), the immunoreactive expression of D 2 receptor in colon decreased ( P <0.01). Compared with the model group, the Bristol fecal scores of the Tianshu and Neiguan groups decreased ( P <0.01), the 1 st contraction wave latent periods were longer ( P <0.01), the numbers of contraction waves in 90 s decreased ( P <0.01), the positive expressions of D 2 receptor in colon increased ( P <0.01, P <0.05). Compared with the Tianshu group, the immunoreactive expression of D 2 receptor in the Neiguan group decreased ( P <0.01). EA at ST 25 and PC 6 can improve the symptoms of colonic motility in IBS rats. The effect of EA at ST 25 is better, which indicates that different meridians and different acupoints play specific effects.

    The purpose of this study was to conduct a meta-analysis comparing rigid gas permeable lenses (RGP) with soft contact lenses (SCL), spectacles and orthokeratology (OK) lenses for myopia control with respect to axial length elongation, spherical equivalent and measures of corneal curvature. Medline, Cochrane, EMBASE, and Google Scholar databases were searched to September 29, 2015 using the following keywords: rigid gas permeable contact lens; refractive error; and refractive abnormalities. Randomized controlled trials, two-arm prospective studies and retrospective studies of children with myopia treated with RGP lenses compared with spectacles, SCL, and OK lenses were included. Outcome measures were changes of axial length, spherical equivalent, flatter meridian, steeper meridian and corneal apical radius. Five studies were included. Three studies reported axial length change after 2-3 years of treatment with RGP lenses and SCL/spectacles and no difference between the groups was noted (pooled mean difference = -0.077, 95% confidence interval [CI]: -0.120 to 0.097, p = 0.840). Two studies reported a change of spherical equivalent after 2-3 years of treatment with RGP lenses and SCL/spectacles, and no difference between the groups was noted (pooled mean difference = 0.275, 95% CI: -0.390 to 0.941, p = 0.417). Two studies compared corneal curvature measures between RGP and OK lenses after 3-6 months of treatment and no differences in any measures of corneal curvature were seen. The effect of RGP lenses and SCL/spectacles on axial length elongation and spherical equivalent and of RGP and OK lenses on corneal curvature in children with myopia was similar.

    In this work an application of a methodology to obtain solar radiation maps is presented. This methodology is based on a neural network system [Lippmann, R.P., 1987. An introduction to computing with neural nets. IEEE ASSP Magazine, 4-22] called Multi-Layer Perceptron (MLP) [Haykin, S., 1994. Neural Networks. A Comprehensive Foundation. Macmillan Publishing Company; Hornik, K., Stinchcombe, M., White, H., 1989. Multilayer feedforward networks are universal approximators. Neural Networks, 2(5), 359-366]. To obtain a solar radiation map it is necessary to know the solar radiation of many points spread wide across the zone of the map where it is going to be drawn. For most of the locations all over the world the records of these data (solar radiation in whatever scale, daily or hourly values) are non-existent. Only very few locations have the privilege of having good meteorological stations where records of solar radiation have being registered. But even in those locations with historical records of solar data, the quality of these solar series is not as good as it should be for most purposes. In addition, to draw solar radiation maps the number of points on the maps (real sites) that it is necessary to work with makes this problem difficult to solve. Nevertheless, with the application of the methodology proposed in this paper, this problem has been solved and solar radiation maps have been obtained for a small region of Spain: Jaen province, a southern province of Spain between parallels 38{sup o}25' N and 37{sup o}25' N, and meridians 4{sup o}10' W and 2{sup o}10' W, and for a larger region: Andalucia, the most southern region of Spain situated between parallels 38{sup o}40' N and 36{sup o}00' N, and meridians 7{sup o}30' W and 1{sup o}40' W.

    Full Text Available Cryptosporidium is a common cause of sporadic diarrheal disease and outbreaks in the United States. Increasingly, immunochromatography-based rapid cartridge assays (RCAs are providing community laboratories with a quick cryptosporidiosis diagnostic method. In the current study, the Centers for Disease Control and Prevention (CDC, the Association of Public Health Laboratories (APHL, and four state health departments evaluated RCA-positive samples obtained during routine Cryptosporidium testing. All samples underwent "head to head" re-testing using both RCA and direct fluorescence assay (DFA. Community level results from three sites indicated that 54.4% (166/305 of Meridian ImmunoCard STAT! positives and 87.0% (67/77 of Remel Xpect positives were confirmed by DFA. When samples were retested by RCA at state laboratories and compared with DFA, 83.3% (155/186 of Meridian ImmunoCard STAT! positives and 95.2% (60/63 of Remel Xpect positives were confirmed. The percentage of confirmed community results varied by site: Minnesota, 39.0%; New York, 63.9%; and Wisconsin, 72.1%. The percentage of confirmed community results decreased with patient age; 12.5% of community positive tests could be confirmed by DFA for patients 60 years of age or older. The percentage of confirmed results did not differ significantly by sex, storage temperature, time between sample collection and testing, or season. Findings from this study demonstrate a lower confirmation rate of community RCA positives when compared to RCA positives identified at state laboratories. Elucidating the causes of decreased test performance in order to improve overall community laboratory performance of these tests is critical for understanding the epidemiology of cryptosporidiosis in the United States (US.

    Granato, Paul A; Chen, Li; Holiday, Iris; Rawling, Russell A; Novak-Weekley, Susan M; Quinlan, Tammy; Musser, Kimberlee A


    Campylobacter enteritis is a food-borne or waterborne illness caused almost exclusively by Campylobacter jejuni and, to a lesser extent, by Campylobacter coli. These organisms produce indistinguishable clinical diseases and together represent the second most common cause of bacterial diarrhea in the United States and the leading cause of enteric infection throughout the world. The conventional approach to the laboratory diagnosis of Campylobacter enteritis is based on the recovery of the organism from a stool specimen, which requires the use of a specialized medium incubated at 42°C for several days in an artificially created microaerophilic environment. Recently, several commercially available enzyme immunoassays (EIAs) have been developed for the direct detection of C. jejuni and C. coli in stool specimens. This study compared conventional culture with three EIA methods, the Premier CAMPY EIA (Meridian Bioscience, Cincinnati, OH), the ProSpecT Campylobacter EIA (Remel, Lenexa, KS), and the ImmunoCard STAT! CAMPY test (Meridian Bioscience, Cincinnati, OH), for the detection of C. jejuni and C. coli in 485 patient stool samples. Discordant results were arbitrated by using an in-house, real-time PCR assay that was developed and validated by a public health reference laboratory. Following analyses of the discrepant specimens by PCR, the sensitivity and specificity of both the Premier CAMPY and ProSpecT Campylobacter EIAs were 99.3% and 98%, respectively, while the ImmunoCard STAT! CAMPY test had a sensitivity of 98.5% and a specificity of 98.2%. By use of the PCR test as the reference standard, culture detected 127 of 135 Campylobacter-positive stool specimens, yielding a sensitivity of 94.1%. These results showed that the three EIAs evaluated in this study provide a rapid and reliable alternative for the laboratory diagnosis of enteric infections with C. jejuni and C. coli and that conventional culture may no longer be recognized as the "gold standard" for

  5. Comparison of ionospheric conductances and auroral luminosities observed simultaneously with the Chatanika radar and the DE 1 auroral imagers

    Robinson, R.M.; Vondrak, R.R.; Craven, J.D.; Frank, L.A.; Miller, K.


    Auroral luminosities at vacuum ultraviolet (VUV) wavelengths are combined with simultaneous and coincident ionospheric electron density measurements made by the Chatanika radar to relate ionospheric conductances to optical emissions. The auroral luminosities are obtained along the magnetic meridian through Chatanika with the auroral imaging photometers on the Dynamics Explorer 1 (DE 1) satellite as the radar scans in the magnetic meridian to measure electron density and conductivity as a function of altitude and latitude. The observations are used to determine an empirical relationship between the luminosities measured at VUV wavelengths and the Hall and Pedersen conductances. Of particular interest is the response of the photometer when using the VUV filter designated 123W. This filter admits the 130.4- and 135.6-nm emissions of atomic oxygen and the Lyman-Birge-Hopfield (LBH) bands of N 2 . Model calculations of the LBH and O I (135.6 nm) contributions to the total measured luminosity indicate that the relation between 123W luminosity and Pedersen conductance is less sensitive to the average energy of the precipitating electrons than the corresponding relation between the Hall conductance and 123W luminosity. This is because both the luminosity and Pedersen conductance decrease with increasing electron energy. The luminosity decreases with increasing energy because the emissions are more strongly absorbed by O 2 above the region of production. The Pedersen conductance decreases with increasing energy because the Pedersen mobility maximizes at an altitude of about 140 km. In contrast, the Hall conductance increases with increasing electron energy, so that the relation between Hall conductance and luminosity depends on the hardness of the precipitation

    To describe a standardized flood-illuminated adaptive optics (AO) imaging protocol suitable for the clinical setting and to assess sampling methods for measuring cone density. Cone density was calculated following three measurement protocols: 50 × 50-μm sampling window values every 0.5° along the horizontal and vertical meridians (fixed-interval method), the mean density of expanding 0.5°-wide arcuate areas in the nasal, temporal, superior, and inferior quadrants (arcuate mean method), and the peak cone density of a 50 × 50-μm sampling window within expanding arcuate areas near the meridian (peak density method). Repeated imaging was performed in nine subjects to determine intersession repeatability of cone density. Cone density montages could be created for 67 of the 74 subjects. Image quality was determined to be adequate for automated cone counting for 35 (52%) of the 67 subjects. We found that cone density varied with different sampling methods and regions tested. In the nasal and temporal quadrants, peak density most closely resembled histological data, whereas the arcuate mean and fixed-interval methods tended to underestimate the density compared with histological data. However, in the inferior and superior quadrants, arcuate mean and fixed-interval methods most closely matched histological data, whereas the peak density method overestimated cone density compared with histological data. Intersession repeatability testing showed that repeatability was greatest when sampling by arcuate mean and lowest when sampling by fixed interval. We show that different methods of sampling can significantly affect cone density measurements. Therefore, care must be taken when interpreting cone density results, even in a normal population.

  7. Ganoderma lucidum Pharmacopuncture for the Treatment of Acute Gastric Ulcers in Rats

    Directory of Open Access Journals (Sweden)

    Jae-Heung Park


    Full Text Available Objectives: The gastric ulcer is a common disorder of the stomach and duodenum. The basic physiopathology of a gastric ulcer results from an imbalance between some endogenous aggressive and cytoprotective factors. This study examined whether Ganoderma lucidum pharmacopuncture (GLP would provide protection against acute gastric ulcers in rats. Methods: Sprague-Dawley rats were divided randomly into 4 groups of 8 rats each: normal, control, normal saline (NP and GLP groups. The experimental acute gastric ulcer was induced by using an EtOH/HCl solution and the normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated once with injections of saline and GLP, respectively. Two local acupoints were used: CV12 (中脘 which is the alarm point of the Stomach Meridian, and ST36 (足三里, which is the sea point of the Stomach Meridian. The stomachs from the rats in each group were collected and analyzed for gross appearance and histology. Also, immunohistochemistry staining for BAX, Bcl-2 and TGF-β1 was performed. Results: Histological observations of the gastric lesions in the control group showed comparatively extensive damage of the gastric mucosa and necrotic lesions had penetrated deeply into the mucosa. The lesions were long, hemorrhagic, and confined to the glandular portions. The lesions were measured microscopically by using the clear depth of penetration into the gastric mucosal surface. The length and the width of the ulcer were measured and the inhibition percentage was calculated. Wound healing of the acute gastric ulcer was promoted by using GLP, and significant alterations of indices in gastric mucosa were observed. Such protection was shown by gross appearance, histology and immunohistochemistry staining for BAX, Bcl-2 and TGF-β1. Conclusion: These results suggest that GLP administered at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol

    Full Text Available AIM: To determine the repeatability of Ophtha Top topography and assess the consistency with intraocular lens (IOL-Master and LenstarLS900 (Lenstar in measuring corneal parameters among cataract patients. METHODS: Totally 125 eyes were enrolled. Corneas were successively measured with Ophtha Top, IOL-Master and Lenstar at least three times. The flattest meridian power (Kf, the steepest meridian power (Ks, mean power (Km, J0 and J45 were recorded. Intra-class correlation coefficients (ICCs, the coefficient of variance (COV, within subject standard deviation (Sw, and test-retest repeatability (2.77Sw were adopted to determine the repeatability. The 95% limit of agreement (95%LOA and Bland-Altman plots were used to assess comparability. RESULTS: Repeatability of Ophtha Top topography for measuring corneal parameters showed the ICCs were all above 0.93, 2.77Sw was lower than 0.31, and the COV of the Kf and Ks was lower than 0.25. The keratometric readings with Ophtha Top topography were flatter than with the IOL-Master and Lenstar devices, while the Pearson correlation coefficients were over 0.97. The J0 and J45 with Ophtha Top topography were smaller compared with Lenstar and IOL-Master, while was comparable between Lenstar and IOL-Master. CONCLUSION: Ophtha Top topography shows excellent repeatability for measuring corneal parameters. However, differences between the Ophtha TOP topography and Lenstar, IOL-Master both in cornea curvature and the astigmatism should be noted clinically.

  9. Sequential selective same-day suture removal in the management of post-keratoplasty astigmatism. (United States)

    Fares, U; Mokashi, A A; Elalfy, M S; Dua, H S


    In a previous study, we proposed that corneal topography performed 30-40 min after the initial suture removal can identify the next set of sutures requiring removal, for the treatment of post-keratoplasty astigmatism. The aim of this study was to evaluate the effect of removing subsequent sets of sutures at the same sitting. 10/0 nylon interrupted sutures were placed, to secure the graft-host junction, at the time of keratoplasty. Topography was performed using Pentacam (Oculus) before suture removal. The sutures to be removed in the steep semi-meridians were identified and removed at the slit-lamp biomicroscope. Topography was repeated 30-40 min post suture removal, the new steep semi-meridians determined, and the next set of sutures to be removed were identified and removed accordingly. Topography was repeated 4-6 weeks later and the magnitude of topographic astigmatism was recorded. A paired-samples t-test was used to evaluate the impact of selective suture removal on reducing the magnitude of topographic and refractive astigmatism. Twenty eyes of 20 patients underwent sequential selective same-day suture removal (SSSS) after corneal transplantation. This study showed that the topographic astigmatism decreased by about 46.7% (3.68 D) and the refractive astigmatism decreased by about 37.7% (2.61 D) following SSSS. Vector calculations also show a significant reduction of both topographic and refractive astigmatism (P<0.001). SSSS may help patients to achieve satisfactory vision more quickly and reduce the number of follow-up visits required post keratoplasty.

  10. Recurrent Forbush decreases and relationship between active regions and M-regions

    International Nuclear Information System (INIS)

    Shah, G.N.; Kaul, C.L.; Razdan, H.; Bemalkhedkar, M.M.


    Recurrent Forbush decreases and recurrent geomagnetic disturbances have been attributed to the solar M-regions, which are sources of high velocity solar plasma streams. A study of recurrent Forbush decreases for the period 1966-75 has been made to examine any possible relationship of M-regions with solar active regions. It is shown that at the onset of the recurrent Forbush decrease at earth, there is a high probability of encountering a class of active regions at central meridian of the sun which give rise to flares of importance >= 28/3N. These active regions are found to be long-lasting and to have large areas as well as high Hsub(α)-intensities. Other active regions, producing flares of only lower importance, are distributed randomly on the sun with respect to the onset of a recurrent Forbush decrease. Using the quasiradial hypervelocity approximation, the base of the leading edge of the high velocity stream, at the onset of a recurrent Forbush decrease at earth, is traced to the solar longitude about 40 deg West of the central meridian. From these results, it is deduced that M-regions are located preferentially to the West of long-lasting, magnetically complex active regions. Earlier studies of the identification of the M-regions on the sun have been re-examined and shown to conform to this positional relationship. A possible mechanism of the development of an M-region to the West of the long-lasting magnetically complex active region is also discussed. (author)

  11. [Synopsis about the hypothesis of "information channel" of channel-collateral system]. (United States)

    Chang, Xi-Lang


    The author of the present paper founded a theorem about the "incompleteness of single channel structure" (nerve, blood vessel, lymphatic, interspace, aperture, etc.) through quantitative and qualitative analysis about the economic information channel in the human body, which eliminates the probability of single channel structure in the information channel of channel (meridian)-collateral system. After comprehensive analysis on the current researches, the author puts forward a neodoxy, i.e., the body "information channel" structure of the channel-collateral system, mainly follows the distribution regularity of systemic statistics, and is not a single specific entity; various layers of the information channel in the main stems of the channel-collaterals are composed of optimized structure tissues. Hence, the structure of this information channel of channel-collateral system is an overall-optimized, sequential and compatible systemic structure. From this neodoxy, the author brings forward a working principle of channel-collaterals, which is supported theoretically by bio-auxology. The longitudinal distribution of the main stems of meridian-collaterals is considered to result from that in the process of the animal evolution, in the animals moving forward, the microscopic complicated movement of intracorporeal information and energy molecules is related to the forward macroscopic and non-uniform movement of organism in trans-measure. Its impulse and kinetic momentum forms a main vector in the longitudinal direction of the body (the direction of the main stem of channel-collaterals). In order to adapt to and utilize natural regularities, the main stems of the channel-collaterals gradually differentiate and evolve in the living organism, forming a whole system. The "hypothesis of biological origin of channel-collateral system" and "that of information channel of the channel-collaterals in the body" constitute a relatively complete theoretical system framework.

    To observe the impacts of different frequencies of electroacupuncture (EA) on post-operative cognitive function and the change in serum S-100beta protein under the compound anesthesia of acupuncture and drugs. One hundred and twenty-four patients of abdominal operation at selective time were randomized into a routine drug anesthesia group (group A, 24 cases), a meridian point 2 Hz group (group B, 26 cases), a me ridian point 2 Hz/100 Hz group (group C, 25 cases), a meridian point 100 Hz group (group D, 24 cases) and a transcutaneous acupoint electric stimulation 2 Hz/100 Hz group (group E, 25 cases). In group A, the endotrachea-lgeneral anesthesia was applied. In the rest groups, the acupuncture anesthesia was induced for 30 min before the endotracheal general anesthesia, at Baihui (GV 20), Yintang (GV 29) and Neiguan (PC 6), with G6805-2 electric acupuncture apparatus used. In group B, the continuous wave and 2Hz in frequency were selected. In group C, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected. In group D, the continuous wave and 100 Hz in frequency were selected. In group E, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected, and the electrode pads were stick on the acupoints and connected with the electric stimulation till the end of operation. Mini-mental state examination (MMSE) was adopted to evaluate and record the changes in cognitive function 1 day before operation and on the 3rd day after operation. The conditions of post-operative cognitive dysfunction (POCD) in the patients and the changes in serum S-100beta protein were monitored before and at the end of operation. The incidence rate of POCD on the 3rd day after operation was 41.7% (10/24) in group A. The incidence rates of POCD were 26.9% (7/26), 16.0% (4/25), 33.3% (8/24) and 16.0% (4/25) in group B, C, D and E separately. Compared with group A, the incidence rate of PCOD in group B, C, D and E were reduced (all P<0.05), the incidence rate in group C and E

  13. Using satellite data for monitoring temperature conditions in fishing areas of the Northeast Atlantic for improving prognosis of fishery. (United States)

    Vanyushin, G.; Borisov, V.; Bogdanov, M.; Bulatova, T.


    The attempt to establish the relationship between current temperature conditions in fishing areas of the Northeast Atlantic (The Norwegian and Barents Seas) and the management of capelin fishery was made. The capelin stock depends on abundance of its predators, as well as on hydrological and climatic conditions, which affect the spawning success, the egg hatching, duration and direction of the larval drift, availability of micro and macrozooplankton food to capelin at its various life stages. Taking into account all these points and importance of capelin for Norwegian and Russian fisheries, we can easily understand an heightened interest in cause of the observed variations in capelin stocks. We are still inclined to see hydrology as the driving force of these variations. Hydrological conditions in concrete year influence on capelin directly, as well as its prey stocks and predators, which, in their turn, affect capelin. The sea surface temperature (SST) is the most suitable index of annual and seasonal variations in hydrological conditions. The temperature data were derived from satellite monitoring basically. Continuous long-term database on the sea surface temperature (SST) comprising results of regional satellite monitoring (the NOAA satellite data) is used to resolve several applied problems particularly for prognosis of fish recruitment strenght. The maps of SST were created with the satellite data, as well as information of vessels, buoies and coastal stations. Here we use the maps of SST in fishing areas of the Norwegian and Barents Seas to clarify impact which duration of warm and cold seasons has on successful survival of capelin during its first year of life. The identified relation between onset of these seasons and their duration can allow us to forecast strength of the next capelin year-classes. Seasonal dynamics of heat content water in areas of young capelin presence were analyzed by the time when the 5°C isotherm passed the 35°E meridian (from the

  14. Global Warming, New Climate, New Atmospheric Circulation and New Water Cycle in North Africa (United States)

    Karrouk, M. S.


    Global warming has now reached the energetic phase of H2O's return to the ground after the saturation of the atmosphere in evaporation since the 80s and 90s of the last century, which were characterized by severe droughts, mainly in Africa.This phase is the result of the accumulation of thermal energy exchanges in the Earth-Ocean-Atmosphere system that resulted in the thrust reversal of the energy balance toward the poles. This situation is characterized by a new thermal distribution: above the ocean, the situation is more in surplus compared to the mainland, or even opposite when the balance is negative on the land, and in the atmosphere, warm thermal advection easily reach the North Pole (planetary crests), as well as cold advection push deep into North Africa and the Gulf of Mexico (planetary valleys: Polar Vortex).This "New Ground Energy Balance" establishes a "New Meridian Atmospheric Circulation (MAC)" with an undulating character throughout the year, including the winter characterized by intense latitudinal very active energy exchanges between the surplus areas (tropical) and the deficit (polar) on the one hand, and the atmosphere, the ocean and the continent on the other.The excess radiation balance increases the potential evaporation of the atmosphere and provides a new geographical distribution of Moisture and Water worldwide: the excess water vapor is easily converted by cold advection (Polar Vortex) to heavy rains that cause floods or snow storms that paralyze the normal functioning of human activities, which creates many difficulties for users and leaves damage and casualties, but ensures water availability missing since a long time in many parts of the world, in Africa, Europe and America.The new thermal distribution reorganizes the geography of atmospheric pressure: the ocean energy concentration is transmitted directly to the atmosphere, and the excess torque is pushed northward. The Azores anticyclone is strengthened and is a global lock by the

  15. The architecture of Hamburg-Bergedorf Observatory 1906 - 1912, compared with other observatories (German Title: Die Architektur der Hamburg-Bergedorfer Sternwarte 1906 - 1912 im Vergleich mit anderen Observatorien) (United States)

    Müller, Peter

    The foundation of the astrophysical observatories in Potsdam-Telegrafenberg in 1874, in Meudon near Paris in 1875 and in Mount Hamilton in California in 1875 resulted in a complete change of observatory architecture. Astrometry had become irrelevant; meridian halls, i.e. an exact north-south orientation, were no longer necessary. The location in the centre of a (university) town was disadvantageous, due to vibrations caused by traffic and artificial light at night. New principles were defined: considerable distance (from the city center), secluded and exposed position (on a mountain) and construction of pavilions: inside a park a pavilion was built for each instrument. Other observatories of this type are: Pic du Midi in the French Alps, built as from 1878 as the first permanent observatory in the high mountains; Nice, Mont Gros, (1879); Brussels, Uccle (1883); Edinburgh, Blackford Hill (1892); Heidelberg, Königstuhl (1896); Barcelona, Monte Tibidado (1902). The original Hamburg Observatory was a modest rectangular building near the Millernrtor; in 1833 it became a State institute. As from 1906 erection of a spacious complex in Bergedorf, 20 km northeast of the city center, took place. Except for the unavailable position on a mountain, this complex fulfilled all principles of a modern observatory: in a park pavilion architecture in an elegant neo-baroque style designed by Albert Erbe (architect of the new Hamburger Kunsthalle with cupola). At the Hamburg Observatory the domed structures were cleverly hierarchised leaving an open view to the south. At the beginning astrometry and astrophysics were equally important; there was still a meridian circle. Apart from that, the instruments were manifold: a large refractor 0.60 m (installed by Repsold/Hamburg, 9 m focal length) and a large reflector 1 m (Zeiss/Jena, 3m focal length). Both were the largest instruments of their kind in the German Empire. In addition, there was the Lippert Astrograph on an elegant polar

    Using Bi-Digital O-Ring Test Resonance Phenomena between 2 identical substances, Omura, Y. succeeded in making the image of the outline of internal organs without use of standard imaging devices since 1982. When he imaged the outline of the stomach on the abdominal wall, a number of the lines came out from upper and lower parts of stomach wall. When the lines were followed, they were very close to the well-known stomach meridians. Subsequently, he found a method of localizing meridians and their corresponding acupuncture points as well as shapes and diameters accurately. At the anatomical location of ST 36 described in traditional textbooks, Omura, Y. found there is no acupuncture point. However, in the close vicinity, there is an acupuncture point which he named as true ST 36 in the mid 1980s, but it is generally known as Omura's ST 36. When the effects of the acupuncture on these 2 locations were compared, Omura's ST 36 (true ST 36) produced very significant well-known acupuncture beneficial effects including improved circulation and blood chemistry, while in the traditional ST 36, the effects were small. In this article, the anatomical relationship between these two acupuncture points, with a short distance of 0.6 approximately 1.5 cm between the centers of these locations, was described. In early 2000, Omura, Y. found Press Needle Stimulation of Omura's ST 36, using "Press-Release" procedure repeated 200 times, 4 times a day to cancer patients reduced high cancer cell telomere of 600-1500ng and high Oncogen C-fos Ab2 and Integrin alpha5beta1 of 100-700ng BDORT units to close to lyg (= 10(-24) g) BDORT units. In addition there was a significant reduction of Asbestos and Hg from cancer cells, while markedly reduced normal cell telomere of lyg was increased to optimally high amounts of 500-530ng BDORTunits. Thus, cancer cells can no longer divide and cancer activity is inhibited. The authors have successfully applied this method for a variety of cancers as well as

  17. The second visual area in the marmoset monkey: visuotopic organisation, magnification factors, architectonical boundaries, and modularity. (United States)

    Rosa, M G; Fritsches, K A; Elston, G N


    The organisation of the second visual area (V2) in marmoset monkeys was studied by means of extracellular recordings of responses to visual stimulation and examination of myelin- and cytochrome oxidase-stained sections. Area V2 forms a continuous cortical belt of variable width (1-2 mm adjacent to the foveal representation of V1, and 3-3.5 mm near the midline and on the tentorial surface) bordering V1 on the lateral, dorsal, medial, and tentorial surfaces of the occipital lobe. The total surface area of V2 is approximately 100 mm2, or about 50% of the surface area of V1 in the same individuals. In each hemisphere, the receptive fields of V2 neurones cover the entire contralateral visual hemifield, forming an ordered visuotopic representation. As in other simians, the dorsal and ventral halves of V2 represent the lower and upper contralateral quadrants, respectively, with little invasion of the ipsilateral hemifield. The representation of the vertical meridian forms the caudal border of V2, with V1, whereas a field discontinuity approximately coincident with the horizontal meridian forms the rostral border of V2, with other visually responsive areas. The bridge of cortex connecting dorsal and ventral V2 contains neurones with receptive fields centred within 1 degree of the centre of the fovea. The visuotopy, size, shape and location of V2 show little variation among individuals. Analysis of cortical magnification factor (CMF) revealed that the V2 map of the visual field is highly anisotropic: for any given eccentricity, the CMF is approximately twice as large in the dimension parallel to the V1/V2 border as it is perpendicular to this border. Moreover, comparison of V2 and V1 in the same individuals demonstrated that the representation of the central visual field is emphasised in V2, relative to V1. Approximately half of the surface area of V2 is dedicated to the representation of the central 5 degrees of the visual field. Calculations based on the CMF, receptive

  18. The integration of acupuncture within medicine in the UK--the British Medical Acupuncture Society's 25th anniversary. (United States)

    Baldry, Peter


    Acupuncture was first used in China, probable about 2000 years ago. When acupuncture first arrived in the West in the 17th century, the principles which the Chinese had used to explain its actions were at variance with current scientific knowledge of the body's structure and function. This led to the rejection of acupuncture by the medical profession in the UK, although individual practitioners adopted it with enthusiasm, usually needling the point of maximal tenderness to treat musculoskeletal pain. Acupuncture was more generally accepted in France and Germany, where the pioneering British physician Felix Mann encountered it in the 1950s. He then taught acupuncture to other medical practitioners and organised regular meetings in London, from which the British Medical Acupuncture Society, BMAS, emerged in 1980. The tradition of biannual scientific meetings has continued since then. The Society has many connections with prominent acupuncturists internationally and is a founder member of the International Council of Medical Acupuncture and Related Techniques (ICMART), and has hosted two world congresses. The Society was involved in standardisation of the meridian nomenclature published in 1990. The Society's scientific journal, Acupuncture in Medicine, was founded in 1981 and has gained international recognition, being indexed on several databases. The Society has established regular teaching courses at different levels, which lead to professional qualifications of Certificate and Diploma. The membership is now open to different health professionals, has grown steadily and now stands at nearly 2500. The Society is administered from offices in Cheshire and London. Many individual members have contributed to the Society's characteristic Western 'medical' approach to acupuncture in which needling is seen as a form of neuromuscular stimulation that owes little to traditional meridians or points. The Society has shown a particular interest in acupuncture for myofascial

    Full Text Available BACKGROUND Pterygium is a common degenerative condition seen in the Indian subcontinent. One of the indications for pterygium excision is visual impairment due to astigmatism. Several mechanisms have been suggested to explain the induced astigmatism – a pooling of the tear film at the leading edge of the pterygium, b mechanical traction exerted by the pterygium on cornea. Hence this study was done retrospectively to assess the effect of pterygium excision on the induced astigmatism. MATERIALS AND METHODS Records of patients operated for primary ocular pterygium by pterygium excision with primary conjunctival closure/ conjunctival autograft in the age group 18 - 70 years over a 1-year period were analysed retrospectively. Pre-operative and post-operative follow up records of day 1 and 1 st month were analysed for changes in corneal curvature and astigmatism using the recorded Automated Refractometry and Keratometry readings. RESULTS Out of the 44 cases analysed retrospectively as 2 groups – pterygium excision with primary conjunctival closure and pterygium excision with conjunctival autograft, majority of them were found to be females (70%, and between 40 - 50 years (90%. Most of the pterygium cases were found to be nasal, and commonly in the right eye and also that the amount of astigmatism increased with the grading of pterygium (p<.000. The most common type of astigmatism noted was “with the rule” astigmatism (75%. The percentage of “against the rule” and oblique astigmatism were 9% & 15% respectively. The decrease in the mean astigmatism after surgery was found to be statistically significant. The difference in t value between the preoperative and one-month postoperative corneal astigmatism was 2.5 D (p<.018. Steepening of both horizontal and vertical meridian was found in conjunctival autograft cases, but in simple closure cases steepening was found only in the vertical meridian. CONCLUSION To conclude, pterygium leads to a

  20. Identification of possible intense historical geomagnetic storms using combined sunspot and auroral observations from East Asia

    D. M. Willis


    Full Text Available Comprehensive catalogues of ancient sunspot and auroral observations from East Asia are used to identify possible intense historical geomagnetic storms in the interval 210 BC-AD 1918. There are about 270 entries in the sunspot catalogue and about 1150 entries in the auroral catalogue. Special databases have been constructed in which the scientific information in these two catalogues is placed in specified fields. For the purposes of this study, an historical geomagnetic storm is defined in terms of an auroral observation that is apparently associated with a particular sunspot observation, in the sense that the auroral observation occurred within several days of the sunspot observation. More precisely, a selection criterion is formulated for the automatic identification of such geomagnetic storms, using the oriental records stored in the sunspot and auroral databases. The selection criterion is based on specific assumptions about the duration of sunspot visibility with the unaided eye, the likely range of heliographic longitudes of an energetic solar feature, and the likely range of transit times for ejected solar plasma to travel from the Sun to the Earth. This selection criterion results in the identification of nineteen putative historical geomagnetic storms, although two of these storms are spurious in the sense that there are two examples of a single sunspot observation being associated with two different auroral observations separated by more than half a (synodic solar rotation period. The literary and scientific reliabilities of the East Asian sunspot and auroral records that define the nineteen historical geomagnetic storms are discussed in detail in a set of appendices. A possible time sequence of events is presented for each geomagnetic storm, including possible dates for both the central meridian passage of the sunspot and the occurrence of the energetic solar feature, as well as likely transit times for the ejected solar plasma

  1. Spatial observation and monitoring of the effects of the "New Climate" Warming on Morocco: Situation of the recent urban floods (United States)

    Karrouk, M. S.


    Since the nineties of the last century, climatological research following a great scientific advance in the field of prediction, not the variability and evolution of the different climatic parameters was beginning to be clearer!But today, since the beginning of 2005, certainly due to oceanic thermal cumulations, and the shift of climatic zones towards poles in selective forms (more intense on the oceans present on the continents); Climatic events do not evolve according to the usual and expected rhythms: atmospheric circulation, precipitation, temperatures, seasonal phenomena, etc. These conditions are a spatiotemporal evolution and distribution, which characterize the new "global climate", by the new atmospheric regime imposing the Meridian Atmospheric Circulation (MAC), alternating the conditions of Freshness (humidity) and Heat (drought) along the year.In this new situation, Morocco, located in the climate transition zone, is fully affected by the "New Climate". Usually, the atmospheric response to major climatic events (ENSO) in this region such as "El Niño" was characterized by the establishment of the NAO positive index, stability and drought, due to dominance Zonal Atmospheric Circulation in winter. On the other hand, in the "La Niña" episode, the negative index of the NAO and the predominant Meridian Atmospheric Circulation and precipitation became abundant.Since the beginning of this century, qualified meteorological events of "exceptional !" causing floods have continued to occur in Morocco and elsewhere, with increasing recurrence, prompting us to wonder about the "new" mode of hydro-thermal function of the climate system that induces torrential rains, as well as its effect on environments and societies.The latest event is the flood disaster in October 2016 in the Laâyoune region of southern Morocco, which specializes in the unusual return of rain in a region considered dry and Saharan.Thanks to spatial observation and monitoring of meteorological

  2. Computerized calculation scheme for toric intraocular lenses. (United States)

    Langenbucher, Achim; Seitz, Berthold


    While a number of intraocular lens (IOL) power prediction formulae are well established for determination of spherical lenses, no common strategy has been published for the computation of toric IOLs. The purpose of this study is to describe a paraxial computing scheme for tracing an axial pencil of rays through the 'optical system eye' containing astigmatic refractive surfaces with their axes at random. The capabilities of this computing scheme are demonstrated with clinical examples. Based on a schematic model eye with spherocylindric surfaces, we use two alternative notations for description of vergences or prescriptions: (1) standard notation (refraction in both cardinal meridians and axis), and (2) component notation (spherical equivalent and cylindric component in 0 degrees and 45 degrees. Refractive surfaces are added to the vergence in component notation, whereas the transformation of the vergence through media is performed in the standard notation for both cardinal meridians. For calculation of the toric lens implant, a pencil of rays is traced through the spectacle and the cornea to the estimated lens position as well as backwards from the retina to the estimated lens position. For calculation of residual spectacle refraction, a pencil of rays is traced backwards from the retina through the toric lens implant and the cornea to the spectacle plane. In example 1 we calculate a 'thin toric lens' for compensation of a corneal astigmatism to achieve a spherical target refraction. In example 2 we compute a 'thick toric lens', which has to compensate for an oblique corneal astigmatism and rotate the spectacle cylinder to the against the rule position to enhance near vision. In example 3 we estimate the residual refraction at the corneal plane after implantation of a thick toric lens, when the cylinder of the lens implant is compensating the corneal cylinder in part and the axis of implantation is not fully aligned with the axis of the corneal astigmatism. This

    Full Text Available To evaluate the effect of different levels of intraocular stray light on kinetic perimetry findings.Twenty-five eyes of 25 healthy young participants were examined by automated kinetic perimetry (Octopus 900 using Goldmann stimuli III4e, I4e, I3e, I2e, and I1e. Each stimulus was presented with a velocity of 3°/s at 24 meridians with 15° intervals. Four levels of intraocular stray light were induced using non-white opacity filter (WOF filters and WOFs applied to the clear plastic eye covers of the participants. The visual acuity, pupil diameter, isopter area, and kinetic sensitivity of each meridian were analyzed for each WOF density.Visual acuity deteriorated with increasing WOF densities (p < 0.01. With a visual acuity of 0.1 LogMAR units, the isopter areas for III4e, I4e, I3e, I2e, and I1e decreased by -32.7 degree2 (-0.2%, -255.7 degree2 (-2.6%, -381.2 degree2 (-6.2%, -314.8 degree2 (-12.8%, and -59.2 degree2 (-15.2%, respectively; kinetic sensitivity for those stimuli decreased by -0.1 degree (-0.1%, -0.8 degree (-1.4%, -1.6 degree (-3.7%, -2.7 degree (-9.7%, and -1.7 degree (-16.2%, respectively. The pupil diameter with each WOF density was not significantly different.Kinetic perimetry measurements with a high-intensity stimulus (i.e., III4e were unaffected by intraocular stray light. In contrast, measurements with the I4e, I3e, I2e, and I1e stimuli, especially I2e and I1e, were affected. Changes in the shape of the isopter resulting from opacity must be monitored, especially in cases of smaller and lower-intensity stimuli.

  4. Revealing metabolite biomarkers for acupuncture treatment by linear programming based feature selection. (United States)

    Acupuncture has been practiced in China for thousands of years as part of the Traditional Chinese Medicine (TCM) and has gradually accepted in western countries as an alternative or complementary treatment. However, the underlying mechanism of acupuncture, especially whether there exists any difference between varies acupoints, remains largely unknown, which hinders its widespread use. In this study, we develop a novel Linear Programming based Feature Selection method (LPFS) to understand the mechanism of acupuncture effect, at molecular level, by revealing the metabolite biomarkers for acupuncture treatment. Specifically, we generate and investigate the high-throughput metabolic profiles of acupuncture treatment at several acupoints in human. To select the subsets of metabolites that best characterize the acupuncture effect for each meridian point, an optimization model is proposed to identify biomarkers from high-dimensional metabolic data from case and control samples. Importantly, we use nearest centroid as the prototype to simultaneously minimize the number of selected features and the leave-one-out cross validation error of classifier. We compared the performance of LPFS to several state-of-the-art methods, such as SVM recursive feature elimination (SVM-RFE) and sparse multinomial logistic regression approach (SMLR). We find that our LPFS method tends to reveal a small set of metabolites with small standard deviation and large shifts, which exactly serves our requirement for good biomarker. Biologically, several metabolite biomarkers for acupuncture treatment are revealed and serve as the candidates for further mechanism investigation. Also biomakers derived from five meridian points, Zusanli (ST36), Liangmen (ST21), Juliao (ST3), Yanglingquan (GB34), and Weizhong (BL40), are compared for their similarity and difference, which provide evidence for the specificity of acupoints. Our result demonstrates that metabolic profiling might be a promising method to

    Fang, Yi-Qing; Lu, Ying; Wang, Yong-Jun


    To observe the clinical efficiency and safety of Benazepril and wind dispelling and dampness removing Chinese herbs were singly or combined used in patients with stage 3 chronic kidney disease (CKD 3), and to provide effective integrative medicine methods for treatment of CKD 3. The CKD 3 was allocated to qi and yin deficiency syndrome, inner disturbance of wind and damp syndrome, stasis in Shen meridian syndrome, and inner accumulation of damp and heat syndrome. Recruited were patients of inner disturbance of wind and damp syndrome accompanied or unaccompanied with the other 3 syndrome types. In the prospective, randomized, double blind controlled study, 60 patients confirmed as primary chronic glomerulonephritis (CGN) were randomly assigned to 3 groups with a total course of treatment for 24 weeks. Patients in the Western medicine group (WM, 23 cases) took Benazepril (10 mg/d). Those in the Chinese medicine group (CM, 20 cases) received treatment by syndrome typing. Those in the combination group (17 cases) used the two methods. The therapeutic efficacy and the occurrence of adverse reactions were observed in the 3 groups. The inner disturbance of wind and damp syndrome accompanied qi and yin deficiency syndrome and stasis in Shen meridian syndrome was most often seen in these patients. It accounted for 75.0% in the CM group, 60.9% in the WM group, and 82.4% in the combination group. Totally 54 patients completed this trial. Of them, there were 19 in the CM group, 19 in the WM group, and 16 in the combination group. There was no significant difference in the total effective rate of Chinese medicine syndrome among the 3 groups (84.2%, 78.9%, and 87.5%, respectively) (P>0.05). As for the total effective rate of WM, it was obviously higher in the combination group than in the WM group and the CM group (100.0%, 94.7%, and 94.7%, respectively) (PBenazepril combined with wind dispelling and dampness removing Chinese herbs showed favorable renal protective effects.

  6. Prediction of post-sunset ESF based on the strength and asymmetry of EIA from ground based TEC measurements (United States)

    Thampi, S. V.; Ravindran, S.; Devasia, C. V.; Pant, T. K.; Sreelatha, P.; Sridharan, R.

    The Coherent Radio Beacon Experiment (CRABEX) is aimed at investigating the equatorial ionospheric processes like the Equatorial Ionization Anomaly (EIA) and Equatorial Spread F (ESF) and their inter relationships. As a part of CRABEX program, a network of six stations covering the region from Trivandrum (8.5°N) to Nainital (29.3°N) is set up along the 77-78° E meridian. These ground receivers basically measure the slant Total Electron Content (TEC) along the line of sight from the Low Earth Orbiting satellites (NIMS). These simultaneous TEC measurements are inverted to obtain the tomographic image of the latitudinal distribution of electron densities in the meridional plane. In this paper, the tomographic images of the equatorial ionosphere along the 77-78°E meridian are presented. The crest intensities in the southern and northern hemispheres also show significant differences with seasons, showing the variability in the EIA asymmetry. The evening images give an indication of the prevailing electrodynamical conditions on different days, preceding the occurrence/non-occurrence of ESF. Apart from this, the single station TEC measurements from the Trivandrum station itself is used to estimate the EIA strength and asymmetry. Since this station is situated at the trough of the EIA, right over the dip equator, the latitudinal gradients on both northern (N) and southern (S) sides can be used to compute the EIA strength and asymmetry. These two parameters, obtained well ahead of the onset time of ESF, are shown to have a definite role on the subsequent ESF activity. Hence, both these factors are combined to define a new `forecast parameter' for the generation of ESF. It has been shown that this parameter can uniquely define the state of the `background ionosphere' conducive for the generation of ESF irregularities as early as 1600 IST. A critical value for the `forecast parameter' has been identified such that when the estimated value for `forecast parameter' exceeds

  7. Structural response of nuclear containment shield buildings with unanticipated construction openings (United States)

    Mac Namara, Sinead Caitriona

    As Nuclear Power Plants age many require steam generator replacement. There is a nickel alloy in the steam generator tubes that is susceptible to stress cracking and although these cracks can be sealed the generator becomes uneconomical without 10%-15% of the tubes. The steam generator in a typical nuclear power plant is housed in the containment structure next to the reactor. The equipment hatch is not big enough to facilitate steam generator replacement, thus construction openings in the dome of the containment structure are required. To date the structural consequences of construction openings in the dome have not been examined. This thesis examines the effects of such openings. The prototype concrete dome is made up of a 2 ft thick dome atop 3 ft thick and 170 ft high cylindrical walls (radius 65.5 ft) with a tension ring 15 ft high and 8 ft thick in between. The dome of the building is cast in two layers; a lower 9 inch layer that serves as the formwork for an upper 15 inch layer. The weight of the dome is carried in axial compression along the hoops and meridians of the dome. The first finite element model uses shell elements and considers two limiting load cases; where the two layers act as one, and where the lower layer carries the weight of both. The openings interrupt the hoops and meridians and the weight of the dome must be redistributed around the openings. Without openings, the stresses due to dead load in the structure are very low when compared to the material strength. The impact of the openings is increased compression stresses near the opening. The maximum stresses are approximately four times larger than in the original structure. These results are confirmed by the second model which is made from layers of solid elements. This model shows a significant difference between the compression on the top surface of the dome, in the affected areas, and that on the bottom surface, leading to shear stresses. These shear stresses are largest around the

    Full Text Available Abstract Background Acupuncture provides a means of peripheral stimulation for pain relief. However, the detailed neuronal mechanisms by which acupuncture relieves pain are still poorly understood and information regarding optimal treatment settings is still inadequate. Previous studies with a short burst of unilateral electroacupuncture (EA in the Tendinomuscular Meridians (TMM treatment model for pain demonstrated a transient dermatomally correlated bilateral analgesic effect with corresponding peripheral modality-specific sensory threshold alterations. However, the impact of EA duration on the analgesic effect in this particular treatment model is unknown. To obtain mechanistically and clinically important information regarding EA analgesia, this current prospective cross-over study assesses the effects of EA duration on analgesia and thermal sensory thresholds in the TMM treatment model. Methods Baseline peripheral sensory thresholds were measured at pre-marked testing sites along the medial aspects (liver and spleen meridians of bilateral lower extremities. A 5-second hot pain stimulation was delivered to the testing sites and the corresponding pain Visual Analog Scale (VAS scores were recorded. Three different EA (5Hz stimulation durations (5, 15 and 30 minutes were randomly tested at least one week apart. At the last 10 seconds of each EA session, 5 seconds of subject specific HP stimulation was delivered to the testing sites. The corresponding pain and EA VAS scores of de qi sensation (tingling during and after the EA were recorded. The measurements were repeated immediately, 30 and 60 minutes after the EA stimulation. A four-factor repeat measures ANOVA was used to assess the effect of stimulation duration, time, location (thigh vs. calf and side (ipsilateral vs. contralateral of EA on sensory thresholds and HP VAS scores.

    Full Text Available To assess cone density as a marker of early signs of retinopathy in patients with type II diabetes mellitus.An adaptive optics (AO retinal camera (rtx1™; Imagine Eyes, Orsay, France was used to acquire images of parafoveal cones from patients with type II diabetes mellitus with or without retinopathy and from healthy controls with no known systemic or ocular disease. Cone mosaic was captured at 0° and 2°eccentricities along the horizontal and vertical meridians. The density of the parafoveal cones was calculated within 100×100-μm squares located at 500-μm from the foveal center along the orthogonal meridians. Manual corrections of the automated counting were then performed by 2 masked graders. Cone density measurements were evaluated with ANOVA that consisted of one between-subjects factor, stage of retinopathy and the within-subject factors. The ANOVA model included a complex covariance structure to account for correlations between the levels of the within-subject factors.Ten healthy participants (20 eyes and 25 patients (29 eyes with type II diabetes mellitus were recruited in the study. The mean (± standard deviation [SD] age of the healthy participants (Control group, patients with diabetes without retinopathy (No DR group, and patients with diabetic retinopathy (DR group was 55 ± 8, 53 ± 8, and 52 ± 9 years, respectively. The cone density was significantly lower in the moderate nonproliferative diabetic retinopathy (NPDR and severe NPDR/proliferative DR groups compared to the Control, No DR, and mild NPDR groups (P < 0.05. No correlation was found between cone density and the level of hemoglobin A1c (HbA1c or the duration of diabetes.The extent of photoreceptor loss on AO imaging may correlate positively with severity of DR in patients with type II diabetes mellitus. Photoreceptor loss may be more pronounced among patients with advanced stages of DR due to higher risk of macular edema and its sequelae.

  10. Dynamics in the Modern Upper Atmosphere of Venus: Zonal Wind Transition to Subsolar-to-Antisolar Flow (United States)

    Livengood, T. A.; Kostiuk, T.; Hewagama, T.; Fast, K. E.


    We observed Venus on 19-23 Aug 2010 (UT) to investigate equatorial wind velocities from above the cloud tops through the lower thermosphere. Measurements were made from the NASA Infrared Telescope Facility using the NASA Goddard Space Flight Center Heterodyne Instrument for Planetary Winds and Composition. High-resolution spectra were acquired on a CO2 pressure-broadened absorption feature that probes the lower mesosphere ( 70 km altitude) with a non-LTE core emission of the same transition that probes the lower thermosphere ( 110 km). The resolving power of λ/Δλ≈3×107 determines line-of-sight velocity from Doppler shifts to high precision. The altitude differential between the features enables investigating the transition from zonal wind flow near the cloud tops to subsolar-to-antisolar flow in the thermosphere. The fully-resolved carbon dioxide transition was measured near 952.8808 cm-1 (10.494 µm) rest frequency at the equator with 1 arcsec field-of-view on Venus (24 arcsec diameter) distributed about the central meridian and across the terminator at ±15° intervals in longitude. The non-LTE emission is solar-pumped and appears only on the daylight side, probing subsolar-to-antisolar wind velocity vector flowing radially from the subsolar point through the terminator, which was near the central meridian in these observations and had zero line-of-sight wind projection at the terminator. The velocity of the zonal flow is approximately uniform, with maximum line-of-sight projection at the limb, and can be measured by the frequency of the absorption line on both the daylight and dark side. Variations in Doppler shift between the observable features and the differing angular dependence of the contributing wind phenomena thus provide independent mechanisms to distinguish the dynamical processes at the altitude of each observed spectral feature. Winds up to >100 m/s were determined in previous investigations with uncertainties of order 10 m/s or less.

    Bernardi, Gabriella


    This book offers a fascinating account of the life and scientific achievements of Giovanni Domenico Cassini, or Cassini I, the most famous astronomer of his time, who is remembered today especially for his observations of the rings and satellites of Saturn and his earlier construction of the great meridian line in the Basilica of San Petronio in Bologna. The various stages of his life are recounted in an engaging style, from his early childhood in Perinaldo and his time at the famous Jesuit College in Genoa, to his later experiences in Bologna and Paris. The emphasis, however, is on the scientific side of his life. The book explores his impressive body of work in diverse fields while also drawing attention to the international character of his endeavors, the rigor of his research, and his outstanding management skills, which combined to make him an early embodiment of the “European scientist.” It was also these abilities that gained him the attention of the most powerfu l king in Europe, Louis XIV of Fran...

  12. Coding Model and Mapping Method of Spherical Diamond Discrete Grids Based on Icosahedron

    Directory of Open Access Journals (Sweden)

    LIN Bingxian


    Full Text Available Discrete Global Grid(DGG provides a fundamental environment for global-scale spatial data's organization and management. DGG's encoding scheme, which blocks coordinate transformation between different coordination reference frames and reduces the complexity of spatial analysis, contributes a lot to the multi-scale expression and unified modeling of spatial data. Compared with other kinds of DGGs, Diamond Discrete Global Grid(DDGG based on icosahedron is beneficial to the spherical spatial data's integration and expression for much better geometric properties. However, its structure seems more complicated than DDGG on octahedron due to its initial diamond's edges cannot fit meridian and parallel. New challenges are posed when it comes to the construction of hierarchical encoding system and mapping relationship with geographic coordinates. On this issue, this paper presents a DDGG's coding system based on the Hilbert curve and designs conversion methods between codes and geographical coordinates. The study results indicate that this encoding system based on the Hilbert curve can express space scale and location information implicitly with the similarity between DDG and planar grid put into practice, and balances efficiency and accuracy of conversion between codes and geographical coordinates in order to support global massive spatial data's modeling, integrated management and all kinds of spatial analysis.

  13. Application thinking on Bian-stone of the acousto-optic effect in the treatment of primary dysmenorrhea (United States)

    Ge, Shu; Chen, Gui-Zhen; Liu, Song-Hao


    In order to identify the relations between the Si-Bin Bian-stone of the mineral composition characteristics and Bian-stone of the good infrared emission features. A detailed study of the Sibin Bian-stone samples was conducted by using the laser Raman spectroscopy and high-resolution transmission electron microscopy (HRTEM). The study is to provide theoretical physical support for Bian-stone in the treatment of primary dysmenorrhea. And Thermal tomography technology (TTM) is intended to be carried out to assess the effects of Bian-stone. The Raman spectroscopic study confirmed the existence of fine-grained pyrite, anatase, calcitepyrite and graphite. It is believed that the combination of good thermal properties of the above 4 minerals make the Sibin Bian-stone as a useful material with very good physiotherapical functions. The ultrasonic has a resonance with the body's biological molecules so that it can improve meridians microcirculation. Hence, the Sibin Bian-stones can be used to make acupuncture tools for stimulating the circulation of the blood in vessels and relieving pains of human beings by utilizing its infrared thermal radiation property. TTM which accepts the heat produced by the metabolism process of life can reflect the energy status information, TTM will be introduced to evaluate effect at the overall level of the abdomen from the thermal image and analyze to derive a comprehensive diagnosis. In sum, this experiment is explored to provide a new idea for the modernization of traditional Chinese medicine.

  14. Visuomotor mental rotation: the reaction time advantage for anti-pointing is not influenced by perceptual experience with the cardinal axes. (United States)

    Neely, Kristina A; Heath, Matthew


    In the visuomotor mental rotation (VMR) paradigm, participants execute a center-out reaching movement to a location that deviates from a visual cue by a predetermined instruction angle. Previous work has demonstrated a linear increase in reaction time (RT) as a function of the amplitude of the instruction angle (Georgopoulos and Massey in Exp Brain Res 65:361-370, 1987). In contrast, we recently reported a RT advantage for an instruction angle of 180 degrees relative to a 90 degrees angle (Neely and Heath in Neurosci Lett 463:194-198, 2009). It is possible, however, that perceptual expertise with the cardinal axes, which are perceptually familiar reference frames, influenced the results of our previous investigation. To address this issue, we employed a VMR paradigm identical to that of our previous work, with the exception that the stimulus array was shifted 45 degrees from the horizontal and vertical meridians. Our results demonstrated that RTs were fastest and least variable when the instruction angle was 0 degrees, followed by 180 degrees, which in turn, was faster than 90 degrees. Such findings establish that the RT advantage for the 180 degrees instruction angle is not influenced by perceptual expertise with the cardinal axes. Moreover, the present results provide convergent evidence that RT is not determined by the angle of rotation; instead, they indicate that response latencies reflect computational differences in the complexity of response remapping.

    Oliver, W.L.; Salah, J.E.


    The Global Thermospheric Mapping Study (GTMS) is a multitechnique experimental pilot study of the Earth's thermosphere designed to map simultaneously its spatial and temporal morphology. This paper provides the background for the study and presents the analysis techniques employed at Millstone Hill and results to date on thermospheric structure and dynamics. The first latitudinal-temporal maps of exospheric temperature obtained from the incoherent scatter radar chain at 70W meridian are presented for the two solstice periods, revealing substantial seasonal differences between them. The observed structure shows a relatively depressed temperature at high latitude in summer in contrast to the mass spectrometer/incoherent scatter 1983 [MSIS-83] empirical model, which shows a maximum temperature at polar latitudes. The MSIS-83 model predictions are in good agreement with the observed latitudinal-temporal structure in winter. Comparison with the numerical predictions made for the June 26-28, 1984 period with the National Center for Atmospheric Research thermospheric general circulation model shows reasonable agreement in the latitudinal gradient but the observations indicate a cooler thermosphere by several hundred degrees. Neutral winds at mid-latitudes are presented showing the expected strong southward winds at night, which are found to be consistent with the temperature gradients observed in the latitudinal maps. There is good agreement in the June winds between the available numerical model calculations and the observations. Work performed elsewhere on the GTMS data base is summarized for completeness

  16. Acupuncture's Cardiovascular Actions: A Mechanistic Perspective. (United States)

    Longhurst, John


    Over the last several decades, there has been an explosion of articles on acupuncture, including studies that have begun to explore mechanisms underlying its analgesic and cardiovascular actions. Modulation of cardiovascular function is most effective during manual and low-frequency, low-intensity electroacupuncture (EA) at a select set of acupoints situated along meridians located over deep somatic nerves on the upper and lower extremities. Stimulation at these acupoints activates underlying sensory neural pathways that project to a number of regions in the central nervous system (CNS) that ultimately regulate autonomic outflow and hence cardiovascular function. A long-loop pathway involving the hypothalamus, midbrain, and medulla underlies EA modulation of reflex increases in blood pressure (BP). Actions of excitatory and inhibitory neurotransmitters in the supraspinal CNS underlie processing of the somatic input and adjustment of autonomic outflow during EA. Acupuncture also decreases elevated blood pressure through actions in the thoracic spinal cord. Reflexes that lower BP likewise are modulated by EA through its actions on sympathetic and parasympathetic nuclei in the medulla. The autonomic influence of acupuncture is slow in onset but prolonged in duration, typically lasting beyond the period of stimulation. Clinical studies suggest that acupuncture can be used to treat cardiac diseases, such as myocardial ischemia and hypertension, associated with overactivity of the sympathetic nervous system.

  17. Current applications of molecular imaging and luminescence-based techniques in traditional Chinese medicine. (United States)

    Li, Jinhui; Wan, Haitong; Zhang, Hong; Tian, Mei


    Traditional Chinese medicine (TCM), which is fundamentally different from Western medicine, has been widely investigated using various approaches. Cellular- or molecular-based imaging has been used to investigate and illuminate the various challenges identified and progress made using therapeutic methods in TCM. Insight into the processes of TCM at the cellular and molecular changes and the ability to image these processes will enhance our understanding of various diseases of TCM and will provide new tools to diagnose and treat patients. Various TCM therapies including herbs and formulations, acupuncture and moxibustion, massage, Gua Sha, and diet therapy have been analyzed using positron emission tomography, single photon emission computed tomography, functional magnetic resonance imaging and ultrasound and optical imaging. These imaging tools have kept pace with developments in molecular biology, nuclear medicine, and computer technology. We provide an overview of recent developments in demystifying ancient knowledge - like the power of energy flow and blood flow meridians, and serial naturopathies - which are essential to visually and vividly recognize the body using modern technology. In TCM, treatment can be individualized in a holistic or systematic view that is consistent with molecular imaging technologies. Future studies might include using molecular imaging in conjunction with TCM to easily diagnose or monitor patients naturally and noninvasively. Copyright © 2011 Elsevier Ireland Ltd.

    The onset times and peak intensities of solar energetic particle (SEP) events at Earth have long been thought to be influenced by the open magnetic fields of coronal holes (CHs). The original idea was that a CH lying between the solar SEP source region and the magnetic footpoint of the 1 AU observer would result in a delay in onset and/or a decrease in the peak intensity of that SEP event. Recently, Gopalswamy et al. showed that CHs near coronal mass ejection (CME) source regions can deflect fast CMEs from their expected trajectories in space, explaining the appearance of driverless shocks at 1 AU from CMEs ejected near solar central meridian (CM). This suggests that SEP events originating in CME-driven shocks may show variations attributable to CH deflections of the CME trajectories. Here, we use a CH magnetic force parameter to examine possible effects of CHs on the timing and intensities of 41 observed gradual E ∼ 20 MeV SEP events with CME source regions within 20° of CM. We find no systematic CH effects on SEP event intensity profiles. Furthermore, we find no correlation between the CME leading-edge measured position angles and SEP event properties, suggesting that the widths of CME-driven shock sources of the SEPs are much larger than the CMEs. Independently of the SEP event properties, we do find evidence for significant CME deflections by CH fields in these events.

  19. The Relation between Coronal Holes and Coronal Mass Ejections during the Rise, Maximum, and Declining Phases of Solar Cycle 23 (United States)

    Mohamed, A. A.; Gopalswamy, N; Yashiro, S.; Akiyama, S.; Makela, P.; Xie, H.; Jung, H.


    We study the interaction between coronal holes (CHs) and coronal mass ejections (CMEs) using a resultant force exerted by all the coronal holes present on the disk and is defined as the coronal hole influence parameter (CHIP). The CHIP magnitude for each CH depends on the CH area, the distance between the CH centroid and the eruption region, and the average magnetic field within the CH at the photospheric level. The CHIP direction for each CH points from the CH centroid to the eruption region. We focus on Solar Cycle 23 CMEs originating from the disk center of the Sun (central meridian distance =15deg) and resulting in magnetic clouds (MCs) and non-MCs in the solar wind. The CHIP is found to be the smallest during the rise phase for MCs and non-MCs. The maximum phase has the largest CHIP value (2.9 G) for non-MCs. The CHIP is the largest (5.8 G) for driverless (DL) shocks, which are shocks at 1 AU with no discernible MC or non-MC. These results suggest that the behavior of non-MCs is similar to that of the DL shocks and different from that of MCs. In other words, the CHs may deflect the CMEs away from the Sun-Earth line and force them to behave like limb CMEs with DL shocks. This finding supports the idea that all CMEs may be flux ropes if viewed from an appropriate vantage point.

  2. Comparative toxicity of eugenol and its quinone methide metabolite in cultured liver cells using kinetic fluorescence bioassays. (United States)

    Thompson, D C; Barhoumi, R; Burghardt, R C


    Comparative kinetic analyses of the mechanisms of toxicity of the alkylphenol eugenol and its putative toxic metabolite (quinone methide, EQM) were carried out in cultured rat liver cells (Clone 9, ATCC) using a variety of vital fluorescence bioassays with a Meridian Ultima laser cytometer. Parameters monitored included intracellular GSH and calcium levels ([Ca2+]i), mitochondrial and plasma membrane potentials (MMP and PMP), intracellular pH, reactive oxygen species (ROS) generation, and gap junction-mediated intercellular communication (GJIC). Cells were exposed to various concentrations of test compounds (1 to 1000 microM) and all parameters monitored directly after addition at 15 s intervals for at least 10 min. Eugenol depleted intracellular GSH, inhibited GJIC and generation of ROS, and had a modest effect on MMP at concentrations of 10 to 100 microM. At high concentrations (1000 microM), eugenol also affected [Ca2+]i, PMP, and pH. Effects of EQM were seen at lower concentrations (1 to 10 microM). The earliest and most potent effects of either eugenol or EQM were seen on GSH levels and GJIC. Coadministration of glutathione ethyl ester enhanced intracellular GSH levels by almost 100% and completely protected cells from cell death caused by eugenol and EQM. These results suggest that eugenol mediates its hepatotoxic effects primarily through depletion of cytoprotective thiols and interference in thiol-dependent processes such as GJIC. Furthermore, our results support the hypothesis that the toxic effects of eugenol are mediated through its quinone methide metabolite.

  3. Comparative study of different osteotomy modalities in maxillary distraction osteogenesis for cleft lip and palate. (United States)

    Yu, Hongbo; Wang, Xudong; Fang, Bing; Shen, Steve Guofang


    Conventional maxillary distraction osteogenesis and anterior maxillary segmental distraction were applied in the treatment of severe maxillary hypoplasia secondary to cleft clip and palate. The aim of the present study was to compare the difference between these 2 osteotomy modalities used for rigid external distraction. Ten patients with severe maxillary hypoplasia secondary to CLP were enrolled in our study. They were randomly divided into 2 groups. Conventional maxillary distraction osteogenesis was performed in 5 patients and anterior maxillary segmental distraction in 5 patients. The preoperative and postoperative lateral cephalograms were compared, and cephalometric analysis was performed. The independent sample t test was used to evaluate the differences between the 2 groups. All patients healed uneventfully, and the maxillae moved forward satisfactorily. The sella-nasion-point A angles, nasion-point A-Frankfort horizontal plane angles, overjets, and 0-meridian to subnasale distances had increased significantly after distraction osteogenesis. Significant differences were found in the changes in palatal length between the 2 groups (P maxillary segmental distraction group. No significant difference in the changes in palatopharyngeal depth or soft palatal length was found. With the ability of increasing the palatal and arch length, avoiding changes in palatopharyngeal depth, and preserving palatopharyngeal closure function, anterior maxillary segmental distraction has great value in the treatment of maxillary hypoplasia secondary to CLP. It is a promising and valuable technique in this potentially complicated procedure. Copyright © 2012 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

  4. Annual compensation for pipelines in Alberta

    International Nuclear Information System (INIS)


    The Surface Rights Board (SRB) in Alberta held a hearing in November 2007 to address three issues involving a pipeline for Enbridge Pipelines (Athabasca) Inc. as well as several land owner issues in Townships 66-68 and Ranges 17-19, all west of the 4th Meridian. The issues the SRB examined were the appropriate amount (i.e. magnitude) of compensation payable under right of entry orders under consideration; the appropriate structure of the compensation award; and to whom the compensation was payable. This document presented a review by the Farmer's Advocate Office (FAO) of the published decision of the SRB. The verbatim decision and rationale used by the SRB to award annual compensation for loss and/or ongoing nuisance and inconvenience was presented. The document could be useful to landowners as they determine their negotiation strategy when faced with considering future pipeline access agreements. The document included a discussion of the context for the decision and a case review. Specific topics that were covered included the rationale for the decision; long term effects of pipeline arguments and SRB commentary; the award and determination; and what still needs to be done. It was concluded that the SRB requires evidence in order to answer several questions regarding the magnitude of any losses, and to what degree, if any, had the nuisance, inconvenience, and loss of rights already been anticipated and factored into the operator's final offer

  5. On the formation of a plasma pressure anisotropy in the dayside magnetosheath

    Directory of Open Access Journals (Sweden)

    B. V. Rezhenov

    Full Text Available We present a numerical solution for the momentum equation of the magnetosheath particles that describes the distribution of the pressure anisotropy of the magnetosheath plasma in the midday meridian plane. The pressure anisotropy is a maximum near the magnetopause subsolar point (p/pVert ≌ 10. The pressure anisotropy is caused by two factors: particles with small pitch angles (VVert>V which travel along the magnetic field lines away from the equatorial plane of the magnetosheath; and particles, after crossing the bowshock, which reach the bulk velocity component directed along the magnetic field lines again, away from the magnetosheath equatorial plane. This velocity increases with increasing distance from the subsolar point of the bowshock, and does not permit particles with large pitch angles (V>VVert to move toward the equatorial plane.

    Tan, Jie; Zhang, Hong; Han, Guodong; Ai, Kun; Deng, Shifeng


    With the Meta-analysis method, the clinical efficacy of acupuncture and other regular methods for aphasia was evaluated, and the acupoints selection for aphasia was explored. The acupuncture literature of clinical randomized control trials for aphasia published in CNKI, WANFANG, VIP and CBM database was searched; the statistical analysis of clinical efficacy of acupuncture and other regular methods for aphasia was performed by using software Revman 5. 2 provided by Cochrane library. A file of Microsoft Excel was established to perform the analysis of acupoints selection based on frequency analysis method, so as to summarize the characteristics and rules. Totally 385 articles were searched, and 37 articles those met the inclusive criteria was included, involving 1,260 patients in the acupuncture group and 1 238 patients in the control group. The Meta-analysis results showed OR = 3.82, 95% Cl [3.01, 4.85]; rhombus was located on the right side and the funnel plot was nearly symmetry, indicating the treatment effect of the acupuncture group for aphasia was superior to the control group (Z = 11.04, P aphasia is superior to that of speech rehabilitation training and medication treatment alone. The clinical treatment for aphasia focuses on its local effect; the main acupoints are in the head and face, and the meridians are governor vessel, extra channels and conception vessel.

  7. Existing and Proposed Urban Geosites Values Resulting from Geodiversity of Poznań City

    Directory of Open Access Journals (Sweden)

    Zwoliński Zbigniew


    Full Text Available Poznań, a city in central-western Poland, is located in the lowland region but has no less attractive geomorphological and human history. It was here that Poland was born at the end of the tenth century. The city’s location is connected with the meridian course of the Warta River valley. In contrast, in the northern part of the city, there is a vast area of the frontal moraines of the Poznań Phase of the Weichselian Glaciation. Against the backdrop of the geomorphological development of the city, the article presents the existing geosites, classified as urban geosites. The present geosites include three lapidaries with Scandinavian postglacial erratics, one of them also with stoneware, a fragment of a frontal push moraine and impact craters. Besides, three locations of proposed geosites with rich geomorphological and/or human history were identified. These are as follows: the peat bog located in the northern part of the city, defence ramparts as exhumed anthropogenic forms, and the Warta River valley. The existing and proposed geosites in Poznań were evaluated in three ways. In general, it should be assumed that the proposed new geosites are higher ranked than the current ones.

  8. Error estimates for the Fourier-finite-element approximation of the Lame system in nonsmooth axisymmetric domains

    International Nuclear Information System (INIS)

    Nkemzi, Boniface


    This paper is concerned with the effective implementation of the Fourier-finite-element method, which combines the approximating Fourier and the finite-element methods, for treating the Derichlet problem for the Lam.6 equations in axisymmetric domains Ω-circumflex is contained in R 3 with conical vertices and reentrant edges. The partial Fourier decomposition reduces the three-dimensional boundary value problem to an infinite sequence of decoupled two-dimensional boundary value problems on the plane meridian domain Ω α is contained in R + 2 of Ω-circumflex with solutions u, n (n = 0,1,2,...) being the Fourier coefficients of the solution u of the 3D problem. The asymptotic behavior of the Fourier coefficients near the angular points of Ω α , is described by appropriate singular vector-functions and treated numerically by linear finite elements on locally graded meshes. For the right-hand side function f-circumflex is an element of (L 2 (Ω-circumflex)) 3 it is proved that with appropriate mesh grading the rate of convergence of the combined approximations in (W 2 1 (Ω-circumflex)) 3 is of the order O(h + N -1 ), where h and N are the parameters of the finite-element and Fourier approximations, respectively, with h → 0 and N → ∞.

  9. Observation of auroral fading before breakup

    International Nuclear Information System (INIS)

    Pellinen, R.J.; Heikkila, W.J.


    We have obtained detailed observations of the onset of auroral breakup using a variety of instruments with time resolution of some tens of seconds. Rapid sequences of all-sky photographs, and fast meridian scans by photometers, show that breakup is usually preceded by moderate brightening, followed by fading of the auroral brightness lasting one or two minutes, before the actual breakup itself. At the time of the fading there is a brief darkening of the poleward sky. Often the breakup is preceded by one or more rapid intensifications, each one preceded by local fading. Pseudo-breakups may also occur without the development of a major event. A bonafide breakup may begin on the fading arc, on an adjacent arc, or in an entirely new region nearby. This optical activity is closely correlated with the development of auroral radar echoes, suggesting that variations in the ionospheric and magnetospheric electric and magnetic fields are responsible for the observed auroral variations. Data from the IMS magnetometer network provide some indication of a correlated response by the local auroral and ionospheric current, although this could be partly due to changes in conductivity. Riometer recordings show a slow decrease in ionsperic radio wave absorption over a period of about ten minutes prior to breakup, with the largest decrease essentially to quiet-time values in the region of auroral fading and subsequent breakup. The implications of these observations regarding the trigger mechanism for the expansion phase of a magnetospheric substorm are discussed. (author)

  10. Magnetic fields and proper motions of sunspots. 1

    International Nuclear Information System (INIS)

    Kalman, B.


    Determining relation between magnetic fields and intrinsic motions of the Sun spots is considered. Based on daily maps of the longitudinal H 1 and transverse H 2 constituents of the magnetic field and a series of photographs of the Sun a comparison was made of motion of shadow nuclei and semishadow fibres with the structure of the magnetic field in the Sun spot group from 7 till 14 of June, 1969. It was found that the spots moved both along and across the direction of the transverse magnetic field. During the movement of spots changes in the structure of H 2 occurred which in the most cases corresponded to reorientation of lines of force along the trajectory behind the moving spot. However, in some cases the structure of the transverse field behind the moving spot became close to the perpendicular one to the trajectory of the past spot, although it could be almost parallel to the trajectory in front of the spot. The best coincidence of orientations of the spot trajectories with the H 2 structure was obtained near the zero line of the longitudinal field. The orientation of fibres of semishadows along H 2 was observed when the group was near the central meridian

  11. Ancient Chinese medicine and mechanistic evidence of acupuncture physiology. (United States)

    Yang, Edward S; Li, Pei-Wen; Nilius, Bernd; Li, Geng


    Acupuncture has been widely used in China for three millennia as an art of healing. Yet, its physiology is not yet understood. The current interest in acupuncture started in 1971. Soon afterward, extensive research led to the concept of neural signaling with possible involvement of opioid peptides, glutamate, adenosine and identifying responsive parts in the central nervous system. In the last decade scientists began investigating the subject with anatomical and molecular imaging. It was found that mechanical movements of the needle, ignored in the past, appear to be central to the method and intracellular calcium ions may play a pivotal role. In this review, we trace the technique of clinical treatment from the first written record about 2,200 years ago to the modern time. The ancient texts have been used to introduce the concepts of yin, yang, qi, de qi, and meridians, the traditional foundation of acupuncture. We explore the sequence of the physiological process, from the turning of the needle, the mechanical wave activation of calcium ion channel to beta-endorphin secretion. By using modern terminology to re-interpret the ancient texts, we have found that the 2nd century B.C.: physiologists were meticulous investigators and their explanation fits well with the mechanistic model derived from magnetic resonance imaging (MRI) and confocal microscopy. In conclusion, the ancient model appears to have withstood the test of time surprisingly well confirming the popular axiom that the old wine is better than the new.

  12. Ammonia in Jupiter’s troposphere from high-resolution 5-micron spectroscopy (United States)

    Giles, Rohini; Fletcher, Leigh; Irwin, Patrick; Orton, Glenn S.; Sinclair, James Andrew


    Jupiter's tropospheric ammonia (NH3) abundance is studied using spatially-resolved 5-micron observations from CRIRES, a high-resolution spectrometer at the Very Large Telescope in 2012. The high resolving power (R=96,000) allows the line shapes of three NH3 absorption features to be resolved. These three absorption features have different line strengths and probe slightly different pressure levels, and they can therefore be used to constrain the vertical profile of NH3 in the 1-4 bar pressure range. The instrument slit was aligned north-south along Jupiter's central meridian, allowing us to search for latitudinal variability. The CRIRES observations do not provide evidence for belt-zone variability in NH3, as any spectral differences can be accounted for by the large differences in cloud opacity between the cloudy zones and the cloud-free belts. However, we do find evidence for localised small-scale variability in NH3. Specifically, we detect a strong enhancement in NH3 on the southern edge of the North Equatorial Belt (4-6°N). This is consistent with the ‘ammonia plumes’ observed by Fletcher et al. (2016, doi:10.1016/j.icarus.2016.06.008) at the 500-mbar level using 10-micron observations from TEXES/IRTF, as well as with measurements by Juno’s Microwave Radiometer (Li et al. 2017, doi:10.1002/2017GL073159).

  13. Polar cap electric field structures with a northward interplanetary magnetic field

    International Nuclear Information System (INIS)

    Burke, W.J.; Kelley, M.C.; Sagalyn, R.C.; Smiddy, M.; Lai, S.T.


    Polar cap electric fields patterns are presented from times when the S3-2 Satellite was near the dawn-dusk meridian and IMF data were available. With B/sub z/> or =0.7γ, two characteristic types of electric field patterns were measured in the polar cap. In the sunlit polar cap the convection pattern usually consisted of four cells. Two of the cells were confined to the polar cap with sunward convection in the central portion of the cap. The other pair of cells were marked by anti-sunward flow along the flanks of the polar cap and by sunward flow in the auroral oval. These observations are interpreted in terms of a model for magnetic merging at the poleward wall of the dayside polar cusp. The sunward flow in the auroral zone is not predicted by the magnetic model and may be due to a viscous interaction between the solar wind and and magnetosphere. The second type, which was observed in some of the summer hemisphere passes and all of the winter ones, was characterized by an electric field pattern which was very turbulent, and may be related to inhomogeneous merging

  14. A new ULF wave analysis for Seismo-Electromagnetics using CPMN/MAGDAS data (United States)

    Yumoto, K.; Ikemoto, S.; Cardinal, M. G.; Hayakawa, M.; Hattori, K.; Liu, J. Y.; Saroso, S.; Ruhimat, M.; Husni, M.; Widarto, D.; Ramos, E.; McNamara, D.; Otadoy, R. E.; Yumul, G.; Ebora, R.; Servando, N.

    The Space Environment Research Center of Kyushu University has obtained geomagnetic data in the Circum-pan Pacific Magnetometer Network (CPMN) region for over 10 years, and has recently deployed a new real-time Magnetic Data Acquisition System (MAGDAS) in the CPMN region and an FM-CW radar network along the 210° magnetic meridian (MM) for space weather research and applications. This project intends to get the MAGDAS network fully operational and provide data for studies on space and lithosphere weather. In connection with this project, we propose a new ultra-low frequency (ULF) wave analysis method to study ULF anomalies associated with large earthquakes using magnetic data. From a case study of the 1999/05/12 Kushiro earthquake with magnitude M = 6.4, we found a peculiar increase of H-component power ratio AR/ AM of Pc 3 magnetic pulsations a few weeks before the earthquake, where AR is the power obtained at Rikubetsu station ( r = 61 km) near the epicenter and AM is the power obtained at a remote reference station, Moshiri ( r = 205 km). It is also found that the H-component power ratio AD/ AY of Pc 3 increased three times just a few weeks before the earthquake and after one week decreased to the normal level, where AD is one-day power at Rikubetsu station and AY is the one-year-average power.

    We have designed and developed, from scratch, a global circulation model (GCM) named THOR that solves the three-dimensional nonhydrostatic Euler equations. Our general approach lifts the commonly used assumptions of a shallow atmosphere and hydrostatic equilibrium. We solve the “pole problem” (where converging meridians on a sphere lead to increasingly smaller time steps near the poles) by implementing an icosahedral grid. Irregularities in the grid, which lead to grid imprinting, are smoothed using the “spring dynamics” technique. We validate our implementation of spring dynamics by examining calculations of the divergence and gradient of test functions. To prevent the computational time step from being bottlenecked by having to resolve sound waves, we implement a split-explicit method together with a horizontally explicit and vertically implicit integration. We validate our GCM by reproducing the Earth and hot-Jupiter-like benchmark tests. THOR was designed to run on graphics processing units (GPUs), which allows for physics modules (radiative transfer, clouds, chemistry) to be added in the future, and is part of the open-source Exoclimes Simulation Platform (

  16. Laying the Foundations of Contemporary Romanian Astronomy (United States)

    Marin, Sorin


    This article describes the first stage in the history of Romanian astronomy represented by the events, processes and evolution which led to the formation of great scientific personalities, development drives and the creation of the material base for the contemporary Romanian astronomy, having a focus point on the activity of Bucharest Observatory. The article discusses the roots of an evolution pathway determined and inspired by the activity of several scientific personalities of Romania such as Stefan Hepites, Spiru Haret, Nicolae Coculescu and others. It also underlines that a great importance for the astronomical research in Romania was given by the outstanding technical value of the main instruments used at the Observatory in the first decades of activity and, consequentially, by their longevity in service: in the Equatorial Dome - the impressive 6 m. Prin-Mertz telescope and in the Meridian Hall - the GautierPrin telescope. This determined the formation of a powerful astrometry division and a research drive which led over time to important scientific works such as the ultraprecise stellar catalogues developed in Romania at Bucharest Observatory, which were appreciated and awarded nationally and internationally. Therefore, the article includes the moments and the people which determined the success of laying the foundations of the Observatory in 1908 and then having completed the initial scientific infrastructure in 1912 when the construction work was finished, and briefly presents the features, scientific utilisation and outputs of its telescopes, some of the best in the world in their golden years.

    Gu, Xingui; Chen, Zelin; Chen, Bo; Fan, Yihua; Chen, Xianghong


    Blistering cupping is special as eliminating wind and dampness as well as removing phlegm and blood stasis, and it achieves effects through suction. In this paper we reviewed relevant literature combined with clinical experience so as to summarize its operation attention through exploring the origin, mechanism and application. We divide the progress into the blistering period, the phlegm-stasis-eliminating period, and the escharosis period according to the changes of bubble and the things pulled out. Blistering cupping creates ways to eliminate concrete unhealthy influences through smoothing meridians and collaterals, such as phlegm and retained fluid, dampness and blood stasis. Thus chronic diseases are relieved. Also,we propose the rules of "blistering acupoints being related to disease location as well as the nature of acupoints and diseases". The therapy has been used to treat diseases of respiratory system, osteoarticular, skin and subcutaneous tissue, mental and behavioral disorders, and tumor, among which the effects of intractable diseases of respiratory and osteoarticular systems are definite. It deserves to be further explored and promoted.

  18. A comparison of field-aligned current signatures simultaneously observed by the MAGSAT and TIROS/NOAA spacecraft

    In order to examine the relative locations of auroral particle fluxes and field-aligned currents and to identify the main charge carriers of the field-aligned currents at auroral latitudes, nearly simultaneous data from the vector magnetometers on MAGSAT and of precipitating electrons with energies between 300 eV and 20 keV observed by TIROS-N and NOAA-6 are compared. For more than fifty cases, MAGSAT and TIROS and/or NOAA orbits occurred within two minutes (mostly within one minute) of each other in the dawn/dusk sectors, during the time the IMS meridian chains of ground magnetometers were operating from November, 1979 through January, 1980. The latitudinal boundaries of precipitating electrons are found to line up within 1 0 with those of the field-aligned current region. Major portions of the upward field-aligned currents in the poleward half of the evening-sector auroral oval and in the equatorward half of the morining-sector auroral oval appear to be carried by the precipitating keV electrons.

  19. Numerical evaluation of magnetic absolute measurements with arbitrarily distributed DI-fluxgate theodolite orientations (United States)

    Brunke, Heinz-Peter; Matzka, Jürgen


    At geomagnetic observatories the absolute measurements are needed to determine the calibration parameters of the continuously recording vector magnetometer (variometer). Absolute measurements are indispensable for determining the vector of the geomagnetic field over long periods of time. A standard DI (declination, inclination) measuring scheme for absolute measurements establishes routines in magnetic observatories. The traditional measuring schema uses a fixed number of eight orientations (Jankowski et al., 1996).We present a numerical method, allowing for the evaluation of an arbitrary number (minimum of five as there are five independent parameters) of telescope orientations. Our method provides D, I and Z base values and calculated error bars of them.A general approach has significant advantages. Additional measurements may be seamlessly incorporated for higher accuracy. Individual erroneous readings are identified and can be discarded without invalidating the entire data set. A priori information can be incorporated. We expect the general method to also ease requirements for automated DI-flux measurements. The method can reveal certain properties of the DI theodolite which are not captured by the conventional method.Based on the alternative evaluation method, a new faster and less error-prone measuring schema is presented. It avoids needing to calculate the magnetic meridian prior to the inclination measurements.Measurements in the vicinity of the magnetic equator are possible with theodolites and without a zenith ocular.The implementation of the method in MATLAB is available as source code at the GFZ Data Center Brunke (2017).

  20. ATS-6 - UCLA fluxgate magnetometer (United States)

    Mcpherron, R. L.; Coleman, P. J., Jr.; Snare, R. C.


    A summary of the design of the University of California at Los Angeles' fluxgate magnetometer is presented. Instrument noise in the bandwidth 0.001 to 1.0 Hz is of order 85 m gamma. The DC field of the spacecraft transverse to the earth-pointing axis is 1.0 + or - 21 gamma in the X direction and -2.4 + or - 1.3 gamma in the Y direction. The spacecraft field parallel to this axis is less than 5 gamma. The small spacecraft field has made possible studies of the macroscopic field not previously possible at synchronous orbit. At the 96 W longitude of Applications Technology Satellite-6 (ATS-6), the earth's field is typically inclined 30 deg to the dipole axis at local noon. Most perturbations of the field are due to substorms. These consist of a rotation in the meridian to a more radial field followed by a subsequent rotation back. The rotation back is normally accompanied by transient variations in the azimuthal field. The exact timing of these perturbations is a function of satellite location and the details of substorm development.
