    2011-12-01

    Alkaptonuria (AKU) is an autosomal recessive disorder caused by a deficiency of homogentisate 1,2 dioxygenase (HGD) and characterized by homogentisic aciduria, ochronosis, and ochronotic arthritis. The defect is caused by mutations in the HGD gene, which maps to the human chromosome 3q21-q23. AKU shows a very low prevalence (1:100,000-250,000) in most ethnic groups, but there are countries such as Slovakia and the Dominican Republic in which the incidence of this disorder rises to as much as 1:19,000. In this work, we summarize the genetic aspects of AKU in general and the distribution of all known disease-causing mutations reported so far. We focus on special features of AKU in Slovakia, which is one of the countries with an increased incidence of this rare metabolic disorder.

    Full Text Available Abstract The epidemic of HIV/AIDS in Indonesia is one of fastest growing among Asian countries. One of the efforts of the government to reduce HIV/AIDS cases is by implementing Information Education and Communication (IEC which is so-called “Aku Bangga Aku Tahu (ABAT”. However, the effectiveness of ABAT and its methods have not been evaluated. The aim of this study is to analyze the effectiveness of IEC of ABAT on knowledge, perception, stigma and HIV/AIDS behavioral prevention among selected high school students. This is a quantitative research, using pre-test, post-test, and control group of Quasi Experimental Design. A number of 221 students were chosen using multistage random sampling, divided into groups of single, multiple and control. The results of this study showed that the IEC of ABAT effectively increased knowledge, perception and preventive behavior, but it had not been able to reduce stigma. IEC of ABAT multiple sessions provided higher impact thanthat of the single session (p < 0.05. It is necessary to improve methods of IEC to encourage the improvement of knowledge, perception, and reduced stigma and HIV/AIDS risk behavior.

    Full Text Available During 2006 until 2007 there were plenty of songs that are lyrical about adultery or polygamy, in line also with the emergence of the phenomenon of polygamy and infidelity by some famous people ranging from businessmen, preachers, politicians, to academics. One of the most popular songs is a song titled “Jadikan Aku yang Kedua”. Surprisingly, although the title shows that this song legalized polygamy, the majority of listeners who request the song to be played in radio stations are women. The research reveals about the marginalization of women that is implicitly contained in a song lyrics. The research method used is critical discourse analysis with analytical techniques using the model of Norman Fairclough. This study uses substantive theoretical framework such as hegemony, ideology, patriarchy, and feminism and the discourse analysis theory from Michael Foucault. The results showed that the Song is a discourse to marginalize women who occupy the first position, while for the second women or femme fatale, this song is empowering them. Song writer has the power to shape the ideology of consumer (listener toward his patriarchal ideology. He wants to use his power to encourage the women to dare to become a femme fatale.

    Full Text Available Tema perubahan sosial yang ada di dalam sebuah novel sudah banyak dikaji dari berbagai perspektif karena kebermanfaatannya dalam mengetahui sejauh mana perubahan sosial di masyarakat itu terjadi. Akan tetapi, penelitian-penelitian itu hanya memaparkan bentuk-bentuk perubahan sosial dan faktor­‐faktor penyebabnya yang ada di dalam novel. Oleh karena itu, selain untuk mengungkap bentuk­‐bentuk dan faktor­‐faktor penyebab perubahan sosial, tujuan penelitian ini adalah untuk menggali arah perubahan sosial dan upaya menangkal perubahan yang bersifat negatif di dalam novel Aku Mencintaimu Shanyuan. Metode yang digunakan adalah metode deskriptif analisis dengan didukung oleh pendekatan sosiologi sastra. Hasil penelitian menunjukkan bahwa di dalam novel Aku Mencintaimu Shanyuan ini terjadi perubahan sosial di masyarakat Desa Resak, Kabupaten Kutai Barat yang diakibatkan oleh interaksi sosial dengan kebudayaan lain. Akan tetapi, perubahan sosial yang disebabkan oleh faktor eksternal itu masih dalam taraf perubahan pada bagian-bagian sistem, sedangkan sistem masih tetap utuh. Oleh karena itu, arah negatif dari perubahan sosial dapat diatasi dengan melestarikan kearifan lokal dan memperdalam agama yang tampak pada tokoh-tokoh dalam novel Aku Mencintaimu Shanyuan. Abstract: The social change theme in a novel has been analyzed from many perspectives for its advantages in understanding how far social change in the society happens. However, those researchers only explain the social change forms and the causal factors. Therefore, in addition to explaining the social change forms and their underlying factors, this research also aims to describe the social change direction and efforts in preventing negative social change in the novel Aku Mencintaimu Shanyuan. The method used in this research is descriptive analysis supported by sociology theory. The result shows that, in the novel, social change occurs among the society of Resak village, West Kutai

    1999-01-01

    We recently showed that alkaptonuria (AKU) is caused by loss-of-function mutations in the homogentisate 1,2 dioxygenase gene (HGO). Herein we describe haplotype and mutational analyses of HGO in seven new AKU pedigrees. These analyses identified two novel single-nucleotide polymorphisms (INV4+31A-->G and INV11+18A-->G) and six novel AKU mutations (INV1-1G-->A, W60G, Y62C, A122D, P230T, and D291E), which further illustrates the remarkable allelic heterogeneity found in AKU. Reexamination of all 29 mutations and polymorphisms thus far described in HGO shows that these nucleotide changes are not randomly distributed; the CCC sequence motif and its inverted complement, GGG, are preferentially mutated. These analyses also demonstrated that the nucleotide substitutions in HGO do not involve CpG dinucleotides, which illustrates important differences between HGO and other genes for the occurrence of mutation at specific short-sequence motifs. Because the CCC sequence motifs comprise a significant proportion (34.5%) of all mutated bases that have been observed in HGO, we conclude that the CCC triplet is a mutational hot spot in HGO.

    Efforts are made to develop a welding design support system capable of increasing reliability and enhancing welding efficiency. Activities are conducted in the six fields of (1) the development of welding process simulation models, (2) development of welded section structure simulation models, (3) development of simulation models for predicting welding caused deformation, (4) integration of the models, (5) analysis of the welding phenomenon, and (6) the elucidation of the defect generation mechanism. In field (1), efforts are made to develop an arc plasma model, a molten pool convective heat transportation model, and a welding process model. In the effort to develop an arc plasma model, studies are made about a stationary axisymmetric arc in its steady state and about a constitutive equation and computation algorithm for developing a model in which a tungsten electrode (cathode) and an arc plasma welding pool (anode) are integrated. Furthermore, the simulation outcomes are experimentally verified. Satisfactory models are obtained as far as qualitative properties are concerned. (NEDO)

    Alkaptonuria (AKU) is a disorder of phenylalanine/tyrosine metabolism due to a defect in the enzyme homogentisate 1,2-dioxygenase (HGD). This recessive disease is caused by mutations in the HGD gene. We report a 14-year-old girl who was referred after presenting black urine. Careful examination revealed ochronosis of the conjunctiva. There was no affection of the cardiac valves. Elevated excretion of homogentisic acid in urine was found. Sequence analysis of the HGD gene from genomic DNA revealed that the patient is a compound heterozygote with a previously described mutation (c.473C>T, p.Pro158Leu), and a novel one (c.821C>T, p.Pro274Leu). Her mother is heterozygous for the novel mutation, while the brother is heterozygous for the previously described mutation. In summary, we describe an alkaptonuric patient with ocular ochronosis and a novel HGD mutation, c.821C>T, p.Pro274Leu.

    1994-01-01

    Detection signals for a specific phenomenon outputted from any of detectors are distributed by way of half mirrors and inputted to a logic discrimination circuit by way of a photoelectric convertor. The photoelectric convertor detects the quantity of light corresponding to the optical signals from more than two detectors which detected the phenomenon, and outputs detection signals to the logic discrimination circuit. If the phenomenon is detected, since both inputs turn ON in the logic discrimination circuit in accordance with the predetermined logical sum, the occurrence of a specific phenomenon is detected. Thus, an optical system substantially comprises half mirrors, reflection mirrors and photoelectric convertor in combination provides a logic circuit. Since the circuit which transmits signals of the detectors is constituted with an optical system using the half mirrors, the number of parts constituting the logic circuit can greatly be saved. In addition, since the optical system comprises mirrors or half mirrors which have been used so far, they can be used, once assembled, quasipermanently, and the reliability can be enhanced greatly.

    Full Text Available Evangelism and da'wah are two obligations or responsibilities of people, Christians and muslims. I wonder how long these two religions involved in a "cold war" or even a real war, because of arrogant fundamentalist notion. Arrogant because with full consciousness has monopolized the truth, and act like they own the only true God. God has been reduced to their own and considers others deify the wrong god. As a result, the shape of evangelism is not far from the impression of christianization, and the form of da'wah not far from the impression of islamization. Whereas, we find the plural phenomenon in Indonesia. In fact, with the philosophy of Bhinneka Tunggal Ika, Indonesian society should be able to appreciate and preserve otherness in harmony better. But reality says different. Christianization and islamization, plural occurs. Intention to write this article, arose from this concern. How evangelism and da'wah should be done in the context of the plurality of Indonesia, so in the end, You and I become Us.

    Full Text Available Definition No reflow is a phenomenon in which myocardial ischemia and reduced antegrade flow occur despite the absence of proximal stenosis, spasm, dissection, or embolic cut off of major distal branches.1 In another word no reflow phenomenon means failure of restoration of myocardial flow despite removal of epicardial coronary obstruction.2 The incidence is 2% with plain balloon angioplasty (PTCA, 7% in patients undergoing rotational atherectomy, 12% for primary percutaneous coronary intervention (PCI, and much higher at 42% for PCI of degenerated Saphenous Vein Graft (SVG.3 No reflow is a strong predictor of mortality after PCI. The mortality of patients who developed no reflow has been estimated to be 8% Predictors of no reflow include a higher plaque burden, thrombus, lipid pools by intra vascular ultra sonography (IVUS, higher lesion elastic membrane cross sectional area, preinfarction angina and thrombolysis in myocardial infarction (TIMI flow grade 0 on the initial coronary angiogram. Mechanism The cause is mainly embolization of atheromatous material (gruel. Particles are composed of cholesterol clefts, lipid rich macrophages, fragments of fibrous cap, necrotic lesion core and fibrin. This is aggravated by microembolization of platelet-rich thrombi that release vasoactive agents (e.g., serotonin and thromboxane A2, leading to intense arteriolar vasopasm in the distal vasculature. In the animal laboratory, experimental no reflow has been shown to be due to the plugging of capillaries by red blood cells and neutrophils, myocyte contracture and local intracellular and interstitial edema.4,5      A loss of capillary autoregulation and severe microvascular dysfunction are the ultimate physiologic consequences of these microscopic anatomic alterations. Debris of varying sizes of particulate has variable effects on microcirculatory plugging. The effect of particle size on microvascular dysfunction has been mostly investigated during

    Full Text Available In the German EvAKuJ observational cohort study, changes in the body mass index standard deviation score (BMI-SDS of overweight and obese children and adolescents as primary outcome of multimodal (short, inpatient or long, outpatient weight-loss interventions are difficult to interpret. Published intention-to-treat (ITT and per protocol data obtained at the end of the intervention (T1, one year (T2, and two years (T3 after its end were used for sensitivity analysis of treatment success rates. The odds ratio and the number needed to treat (NNT for BMI-SDS reduction of at least −0.2 (successful treatment and at least −0.5 (good treatment success were related to spontaneous BMI-SDS reduction rates in a hypothetical control group (control event rate, CER. At T1, treatment seems to be effective up to a CER of 10% in inpatients and of 5% in outpatients. ITT analysis, compromised by a loss to follow-up of 81 to 90% (inpatients and 57 to 66% (outpatients, indicated that treatment may become less effective at a CER above 1% in inpatients (e.g., successful treatment at T2: NNT=106, at T3: NNT=51, and above 5% in outpatients (successful treatment at T2: NNT=7, at T3: NNT=8; good treatment success at T2 and T3: NNT=25. Positive short-term effects of inpatient treatment of overweight and obese children and adolescents may not be maintained in the long term. Long-term effectiveness of outpatient treatment may depend on age and the degree of overweight.

  1. The crossed phrenic phenomenon.

    2017-06-01

    The cervical spine is the most common site of traumatic vertebral column injuries. Respiratory insufficiency constitutes a significant proportion of the morbidity burden and is the most common cause of mortality in these patients. In seeking to enhance our capacity to treat specifically the respiratory dysfunction following spinal cord injury, investigators have studied the "crossed phrenic phenomenon", wherein contraction of a hemidiaphragm paralyzed by a complete hemisection of the ipsilateral cervical spinal cord above the phrenic nucleus can be induced by respiratory stressors and recovers spontaneously over time. Strengthening of latent contralateral projections to the phrenic nucleus and sprouting of new descending axons have been proposed as mechanisms contributing to the observed recovery. We have recently demonstrated recovery of spontaneous crossed phrenic activity occurring over minutes to hours in C 1 -hemisected unanesthetized decerebrate rats. The specific neurochemical and molecular pathways underlying crossed phrenic activity following injury require further clarification. A thorough understanding of these is necessary in order to develop targeted therapies for respiratory neurorehabilitation following spinal trauma. Animal studies provide preliminary evidence for the utility of neuropharmacological manipulation of serotonergic and adenosinergic pathways, nerve grafts, olfactory ensheathing cells, intraspinal microstimulation and a possible role for dorsal rhizotomy in recovering phrenic activity following spinal cord injury.

  2. Raynaud’s phenomenon

    2011-09-01

    Full Text Available Raynaud’s phenomenon (RP is a vasospastic disorder characterized by episodic color changes of blanching, cyanosis, and hyperemia in response to cold and/or emotional stress. Although most typically noted in the fingers, the circulation of the toes, ears, nose and tongue is also frequently affected. Population studies have shown that RP in adults is more common in women than men, with prevalence estimates ranging from 4% to 30%. Geographic variations in the prevalence reflect differences in climate. RP may be a primary or a secondary process. LeRoy and Medsger suggested criteria for primary RP: symmetric attacks, the absence of tissue necrosis, ulceration or gangrene, the absence of a secondary cause, negative antinuclear antibodies, normal nailfold capillaroscopy and a normal erythrocyte sedimentation rate. Secondary RP is characterized by an age of onset of more than 30 years, painful and asymmetric attacks, ischemic skin lesions, positive autoautoantibodies, capillaroscopic abnormalities and/or clinical features suggestive of connective tissue diseases (CTDs. Among the CTDs, systemic sclerosis has the highest frequency of RP. Finding a cause for RP requires a knowledge of the patient’s occupational, smoking, drug history, physical examination, nailfold capillaroscopy, routine laboratory tests and autoantibodies. Furthermore, RP should be distinguished from acrocyanosis, a condition characterized by continuous cyanosis of the hands or feet that is aggravated by cold temperature. The most important instruction to the patient is abstinence from any smoking, offending drugs should be discontinued, and abrupt changes in temperature. If these measures are inadequate, calcium-channel blockers are the most widely used (nifedipine 30 mg up to 90 mg daily. Alternatively, sympatholytic agent (prazosin, angiotensin II -receptor type I antagonist (losartan, selective sertonin-reuptake inhibitor (fluoxetine may be useful. In the severe cases the role of

  3. The tsunami phenomenon

    Röbke, B. R.; Vött, A.

    2017-12-01

    With human activity increasingly concentrating on coasts, tsunamis (from Japanese tsu = harbour, nami = wave) are a major natural hazard to today's society. Stimulated by disastrous tsunami impacts in recent years, for instance in south-east Asia (2004) or in Japan (2011), tsunami science has significantly flourished, which has brought great advances in hazard assessment and mitigation plans. Based on tsunami research of the last decades, this paper provides a thorough treatise on the tsunami phenomenon from a geoscientific point of view. Starting with the wave features, tsunamis are introduced as long shallow water waves or wave trains crossing entire oceans without major energy loss. At the coast, tsunamis typically show wave shoaling, funnelling and resonance effects as well as a significant run-up and backflow. Tsunami waves are caused by a sudden displacement of the water column due to a number of various trigger mechanisms. Such are earthquakes as the main trigger, submarine and subaerial mass wastings, volcanic activity, atmospheric disturbances (meteotsunamis) and cosmic impacts, as is demonstrated by giving corresponding examples from the past. Tsunamis are known to have a significant sedimentary and geomorphological off- and onshore response. So-called tsunamites form allochthonous high-energy deposits that are left at the coast during tsunami landfall. Tsunami deposits show typical sedimentary features, as basal erosional unconformities, fining-upward and -landward, a high content of marine fossils, rip-up clasts from underlying units and mud caps, all reflecting the hydrodynamic processes during inundation. The on- and offshore behaviour of tsunamis and related sedimentary processes can be simulated using hydro- and morphodynamic numerical models. The paper provides an overview of the basic tsunami modelling techniques, including discretisation, guidelines for appropriate temporal and spatial resolution as well as the nesting method. Furthermore, the

    Full Text Available Mycosis fungoides (MF is the most frequent type of primary cutaneous T-cell/NK-cell lymphoma. The Koebner phenomenon is defined as the appearance of cutaneous lesions on previously noninvolved skin following trauma and is observed in a series of cutaneous diseases including psoriasis, lichen planus, viral warts, molluscum contagiosum, etc. In this case report, 3 patients with longstanding MF are presented, the 1st with the appearance of a circumscribed early-stage type MF lesion rapidly following a surgical excision of an infundibular cyst, the 2nd with the appearance of a unique unilateral palmar tumoral MF lesion at the pressure site of a crutch, and the 3rd presented localized MF early stage lesions at the friction site of a belt. This report suggests that some MF patients may experience Koebner phenomenon-induced MF lesions and that MF should be added to the long list of skin diseases potentially exhibiting the Koebner phenomenon.

    Basic data for the above subject were collected through technical research on the melt welding of dissimilar metals and through conducting experiments under microgravity concerning the phenomenon of melt welding. The technical research covered reports published in the past 25 years on the welding or bonding of dissimilar materials. For each of the combinations of dissimilar materials of steel, nonferrous metal, and ceramics for producing a transitional joint, investigations were conducted as to whether dissimilar metal welding or bonding was currently feasible under each of the welding or bonding methods, and problems were extracted and remedies were gathered. No melt welding technology was found, however, capable of directly welding dissimilar materials for a transitional joint in which intermetallic compounds were to be formed. In a melt welding experiment conducted under microgravity, investigations were conducted into the effect of surface tension and gravity on convection inside a molten pool and into the bonding of dissimilar materials for which Al/Cu and Al/Mg were involved. It was then shown that microgravity is effective in mitigating stirring and segregation in a molten pool. (NEDO)

    1981-01-01

    To investigate resonance phenomenon in classical cepheids, the non-linear radial oscillation of stars is studied based on the assumption that the non-adiabatic perturbation is expressed in terms of van der Pol's type damping. Two- and three-wave resonance in this system is applied to classical cepheids to describe their bump and double-mode behavior. The phase of bump and the depression of amplitude are explained for bump cepheids. The double-periodicity is shown by the enhancement of the third overtone in three-wave resonance. Non-linear effect on resonant period is also discussed briefly. (author)

    Highlights: → CCFL mechanisms, correlations, parameters and related variables were reviewed extensively. → Consideration of geometrical effects is crucial for meaningful comparison and review. → Differentiation between 'onset of CCFL' and 'deflooding/partial delivery' data is required. → Following 2+3, new correlations for onset of CCFL according to liquid velocity ranges were suggested. → Large number of correlations was compared against large data bank that considers points 2+3. - Abstract: Counter current flow limitation CCFL is an important phenomenon for numerous engineering applications and safety of light water reactors. In particular, the possible occurrence of CCFL in the hot-leg of a PWR during SBLOCA or LOCA accidents is of special interest for nuclear safety research. A review of the related literature has made in order to present the most important studies about the phenomenon and to reach common general understanding of the different factors that govern CCFL. Eventually this will allow explaining contradictions among different explanations provided by different authors. Most important factors were geometrical characteristics, liquid superficial velocity, and physical properties. The review shows that despite numerous experimental works, many scaling and geometrical effects are still not fully understood. For Instance there exist no consistent explanation of the channel diameter and inclined riser length effect upon results. The same can be stated-though to a minimum extent - for the inclination angle while channel length (or channel to diameter ratio) effect was clear and consistent. Since most experimental work was done in down-scaled hot-leg simulators, it becomes interesting to build a coherent knowledge about these effects and to explain arising contradictions in order to safely extrapolate results to full-scale hot-leg. The review has shown that many differences were simply due to geometrical effects, this leads to the need to

  11. The Phenomenon of Dental Fear

    DEFF Research Database (Denmark)

    Moore, Rod

    Odontophobia is a rather unique phobia with special psychosomatic components that impact on the dental health of odontophobic persons. It also has psychosocial components largely as a result of destruction of the teeth and subsequent embarrassment that can affect a person and cause a vicious cycle...... of dental fear (see fig. 1). The phenomenon is facilitated by misunderstandings and myths generated by both patients and dentists (see table 1 for examples). The most common reasons given in the literature for such strong fears of dental treatment are: 1) bad experiences in childhood for 85% of cases, 2......) feeling of powerlessness and lack of control over personal emotional reactions and over the social situation in the dental chair, 3) social learning processes in which the image of the dentist is cast in a negative light by the mass media or by the person's relatives or friends and 4) that the person has...

    Full Text Available This article is about increase corruption in private sector as commercial corruption. This establishes a wide understanding of that phenomenon in social science and law. Corruption and bribery are types of fraud and are linked with the private sector too. Although certain types of corruption will decline as the private sector grows and consolidates, other new types involving private sector firms may increase. The commercial corruption can be described as relation inside of an organization and as relation between firms. Corruption in private sector in Poland is connected with social distrust and specific organizational culture, too. Commercial corruption is a familiar feature of their societies and has been the focus of law enforcement and institutional reform. Many others problems do not change the fact that such corruption is a new important problem and causes lost of competitiveness and creates a substitute for fair market and competition in Polish economy and abroad.

    Full Text Available Graham Dinsdale, Ariane L Herrick Centre for Musculoskeletal Research, Institute of Inflammation and Repair, Salford Royal NHS Foundation Trust, University of Manchester, Manchester Academic Health Science Centre, Manchester, UK Abstract: Raynaud's phenomenon (RP is common, and in most patients is primary (idiopathic when due to reversible vasospasm and does not progress to irreversible tissue injury. However, in those patients for whom RP is secondary to an underlying disease (eg, systemic sclerosis or atherosclerosis, progression to digital ulceration or critical ischemia can occur. Therefore, the key question for the clinician is “Why does this patient have RP?” Vascular diagnostics play a key role in answering this. In this review, we firstly discuss the different vascular investigations relevant to clinical practice: nail fold capillaroscopy (including the different methodologies for examining the nail fold capillaries, and the role of capillaroscopy in helping to differentiate between primary and systemic sclerosis-related RP, thermography (available in specialist centers, and evaluation of large vessel disease (for example, due to atherosclerosis. We then discuss research tools, mainly laser Doppler methods, including laser Doppler imaging and laser speckle contrast imaging. These are commercially available as complete imaging systems and are (relatively easy to use. The main current goal in vascular imaging research is to validate these novel state-of-the-art techniques as outcome measures of digital vascular disease, and then apply them in early and later phase studies of new treatment approaches, thus facilitating drug development programs. Keywords: Raynaud's phenomenon, systemic sclerosis, nail fold capillaroscopy, thermography, laser Doppler, angiography

    For the conventional high-speed welding robot, the welding current was controlled mainly for reducing the spatters during short circuits and for stabilizing the beads by the periodic short circuits. However, an increase of deposition amount in response to the speed is required for the high-speed welding. Large-current low-spatter welding current region control was added. Units were integrated into a package by which the arc length is kept in short without dispersion of arc length for welding without defects such as undercut and unequal beads. In automobile industry, use of aluminum parts is extended for the light weight. The welding is very difficult, and automation is not so progressing in spite of the poor environment. Buckling of welding wire is easy to occur, and supply of wire is obstructed by the deposition of chipped powders on the torch cable, which stay within the contact chip resulting in the deposition. Dislocation of locus is easy to occur at the corner of rectangular pipe during the welding. By improving these troubles, an aluminum MIG welding robot package has been developed. 13 figs.

  15. Leidenfrost phenomenon on conical surfaces

    2016-09-01

    The Leidenfrost state is typically studied by placing droplets on flat or slightly curved surfaces. Here this phenomenon is investigated by depositing water in hot conical bowls. We found that this phase exists even for large amounts of liquid in very narrow cones without considerable effect of the confinement on the Leidenfrost transition temperature TL. At a fixed temperature, T >TL , the total evaporation time τ has a nonmonotonic dependence on the angle of confinement θ : for large volumes (˜20 ml) on flat surfaces (θ ˜0∘ ), vapor chimneys appear and accelerate the evaporation rate, their frequency diminishes as θ augments and becomes zero at a certain angle θc, at which τ reaches its maximum value; then, τ decreases again at larger angles because the vapor layer holding up the water becomes thinner due to the increase of hydrostatic pressure and because the geometry facilitates the vapor expulsion along the conical wall. For small volumes (˜1 ml), surface tension mainly determines the drop curvature and the lifetime is practically independent of θ . Different chimney regimes and oscillation patterns were observed and summarized in a phase diagram. Finally, we developed a simple model to decipher the shape adopted by the liquid volume and its evolution as a function of time, and the predictions are in good agreement with the experimental results.

  16. The phenomenon of retarded potentials

    2003-01-01

    The logic simulation of process of time delay of potential on a moved body - recipient resulted in the deduction about cyclic irregularity of time delay, that means, that the moved body makes longitudinal vibrations. A conclusion is drawn that length of longitudinal vibrations depending from three variable: the law of interaction, spacing interval between bodies of interaction and phase velocity looks like: λ=Hv ph /R·F(R) (1), where λ- length of oscillations; H- factor of proportionality; v ph - phase velocity of a body; R - distance between test and central bodies R(t); F(R) - law of interaction. So far as λ=v ph /v, and R·F(R)=∫ ∞ R F(R)dR=E move , then formula (1) will be transformed into: E move =Hv pv /λ=Hv. Thus, the energy of radiating having the similar law is only reflex of motion of a matter. The energy of oscillating motion can be expressed through linear maximal velocity. It is established, that different expressions of the same energy, result in the law of a view of a proportion for lengths of de Broglie's waves: It shows that de Broglie's waves - the actual oscillating motions of bodies, as demonstrate interference and diffraction pictures at a dissipation of the accelerated particles on crystalline gratings. This deduction has far-reaching consequences for finding - out of the cause bases of the laws of a nature. So, the quantum mechanics becomes partition of mechanics of solids and is comprises all interactions. The nuclear energy is not 'defect of mass', but is 'defect' of energy of oscillating motion: ΔE=H v1 -H v2 . Definition of real cause of nuclear energy is very important for construction of model of nuclei and for development of physics as the whole. The interconnection of the phenomenon of longitudinal vibrations of moved bodies, as result of irregularity of time delay of potential, with many other natural phenomena is looked through. By such, as: motion of planets and electrons on elliptical orbits, oscillating of dipping drips

  17. Risk as a social phenomenon.

    Jamison, Wesley V

    2003-01-01

    What do nuclear power, smoking, and eating beef have in common? The answer is multifaceted. They all share aspects of mass production and consumption, and therefore consumer confidence comes into play in evaluating each of the products' merits. They all produce some level of anxiety--be it in response to adverse media coverage, or the successes of adversarial interest groups in publicizing those products' weaknesses--among consumers who wonder what if any level of the product should be consumed. Finally, nuclear power, smoking, and eating beef all share risk; that is, the perceived and real detriments of producing and consuming those products. Whether or not the associated risks--from increased cancer to increased heart disease--are real is beside the point. When talking about risk, scientific education must deal with the perception of risk as much as its reality. Risk is a socially defined phenomenon, and as such, the successful scientists/communicator must understand the social evaluations of it. While many scientists take a rational view of risk evaluation and consumers often make rational decisions about technological and scientific risk based upon the costs and benefits of that technology, this approach is problematic for three reasons. First, the nature of modern risks has changed in that risk is complex, incomprehensible and uncontrollable to the average person. Second, the rational approach assumes that all costs and benefits of a technology, both real and potential, both current and future, can be known and therefore rationally evaluated. This is not the case. Third, evidence from Europe indicates that trust in information sources about risk has fallen, and thus classic scientific education campaigns that rely upon increasing public knowledge and acceptance of technological and scientific risk are problematic. Because of these factors we argue that effective scientific response must begin to understand the social components of risk if campaigns to shape

    Raynaud's phenomenon is a currently vascular syndrome (8 to 10% of women and 3 to 5% of men). It was defined as episodic ischaemia of the fingers, toes, nose, ears and nipples, which presents clinically as pallor, cyanosis, and often rubor of the skins, in response to cold, emotional stimuli and vasoconstriction agents. The phenomenon is caused by a vasoconstriction of arterials skin. In severe forms of the phenomenon, we can see ulcerations and necrosis. We report here two cases of rhytidectomy flap necrosis in Raynaud's Phenomenon. After review of literature, we explain the elements of physiopathology whose can explain these complications and we try to establish recommendations to these complications.

    Full Text Available This article focuses on exemplifying the features of discrimination phenomenon in the workplace, a phenomenon that has appeared in the Romanian social studies only in the last 4 years. Mobbing phenomenon has been analyzed by several countries in Europe such as England, France, Germany; after these analyzes it has been found that this phenomenon refers only to actions of intense psychological pressure. Actions are geared to a single employee, in order to cause it to leave its job. Without these measures, dismissal of the employee would lead to numerous legal problems on the employer. In conclusion, employee who is the subject of mobbing phenomenon must endure a long period of time a series of injustices focused on himself, but also extremely high humiliation, which determines him to mentally give up and take the decision to resign.

    Following up on earlier investigations, the present research aims at validating the construct impostor phenomenon by taking other personality correlates into account and to examine whether the impostor phenomenon is a construct in its own right. In addition, gender effects as well as associations with dispositional working styles and strain are examined. In an online study we surveyed a sample of N = 242 individuals occupying leadership positions in different sectors. Confirmatory factor analyses provide empirical evidence for the discriminant validity of the impostor phenomenon. In accord with earlier studies we show that the impostor phenomenon is accompanied by higher levels of anxiety, dysphoric moods, emotional instability, a generally negative self-evaluation, and perfectionism. The study does not reveal any gender differences concerning the impostor phenomenon. With respect to working styles, persons with an impostor self-concept tend to show perfectionist as well as procrastinating behaviors. Moreover, they report being more stressed and strained by their work. In sum, the findings show that the impostor phenomenon constitutes a dysfunctional personality style. Practical implications are discussed.

    Electric conductive plastic composites have a wide potential for commercial applications, some examples are EMI shielding housings and components in automotive industry and in consumer electronics, equipments in health care sector and fuel cell components. A phenomenon in conductive composites, especially in composites with carbon based fillers, is change of thermal induced change in conductivity as a result of morphological transitions. Usually the observed changes are practically irreversible. The phenomenon may cause increasing resistivity, usually called as 'positive temperature coefficient' (PTC) or decreasing resistivity, called 'negative temperature coefficient' (NTC), where the new morphology created by heat treatment is more favorable for electric conductivity compared to the original state. The existence of NTC is a sing of the lost potential in material design and processing. Therefore detailed information about the phenomenon gives us tools to develop high performance conductive materials. It this paper we discuss about NTC phenomenon observed in PP composites with CNT or in-situ synthesized CNT-PANi hybrid nanofiller with an amphiphilic dispersing agent. The goal of the paper is not to present a comprehensive model of this phenomenon; we present some experimental results which may be related to polymer-filler interactions. These details are a part of this complicated phenomenon.

    This paper applies a nonlinear analysis method to show that hysteresis phenomenon, due to the Saddle-node bifurcation, may occur in the nuclear reactor. This phenomenon may have significant effects on nuclear reactor dynamics and can even be the beginning of a nuclear reactor accident. A system of four dimensional nonlinear ordinary differential equations was considered to study the hysteresis phenomenon in a typical nuclear reactor. It should be noted that the reactivity was considered as a nonlinear function of state variables. The condition for emerging hysteresis was investigated using Routh-Hurwitz criterion and Sotomayor's theorem for saddle node bifurcation. A numerical analysis is also provided to illustrate the analytical results.

    Full Text Available The phenomenon of “social media” has more to do with its cultural positioning than its technological affordances. Rooted in the broader “Web 2.0” landscape, social media helped engineers, entrepreneurs, and everyday people reimagine the role that technology could play in information dissemination, community development, and communication. While the technologies invoked by the phrase social media have a long history, what unfolded in the 2000s reconfigured socio-technical practices in significant ways. Reflecting on the brief history of social media, this essay argues for the need to better understand this phenomenon.

    Full Text Available In this paper I develop a phenomenology of religious experience through the notion of keyphenomenon. My analysis moves from a general phenomenology of situation, in which we have to relate different phenomena according to a sense. What does “according to a sense” mean? My suggestion is that we should look for a relationship among these data when we find a key-phenomenon (among a series of phenomena that would enlighten all the others. This key-phenomenon would show a non-phenomenal meaning which would make all the others understandable. Each other datum, therefore, becomes the witness of invisible meaning through a key-witness. The key-phenomenon we choose determines the role (i.e., the truth of each datum within its situation. This phenomenological relationship belongs to both the sense of day-life situations, and that one of possible religious situations. If the religious interpretation of a situation depends on our choice of key-phenomenon, or key-witness, we have to define what kind of keyphenomenon constitutes a religious intuition.

    The aim of this review was to evaluate the balling phenomenon which occurs typically in Selective Laser Sintering (SLS). The balling phenomenon is a typical SLS defect, and observed in laser sintered powder, significantly reduces the quality of SLS, and hinders the further development of SLS Technology. Electronic database searches were performed using Google Scholar. The keywords "laser sintering, selective laser sintering, direct metal laser melting, and balling phenomenon" were searched in title/abstract of publications, limited to December 31, 2016. The inclusion criteria were SLS, balling phenomenon, some alloys (such as Cr-Co, iron, stainless steel, and Cu-based alloys) mechanical properties, microstructure and bond strength between metal-ceramic crown, laboratory studies, full text, and in English language. A total of 100 articles were found the initial search and yielded a total of 50 studies, 30 of which did not fulfill the inclusion criteria and were therefore excluded. In addition, 20 studies were found by screening the reference list of all included publications. Finally, 40 studies were selected for this review. The method in question is regulated by powder material characteristics and the conditions of laser processing. The procedure of formation, affecting factors, and the mechanism of the balling effect are very complex.

    This study investigates the well-documented phenomenon of phase transition in financial markets using combined information from both return and volume changes within short time intervals. We suggest a new measure for the phase transition behaviour of markets, calculated as a return distribution conditional on local variance in volume imbalance, and show that this measure successfully captures phase transition behaviour under various conditions. We analyse the intraday trade and quote dataset from the KOSPI 200 index futures, which includes detailed information on the original order size and the type of each initiating investor. We find that among these two competing factors, the submitted order size yields more explanatory power on the phenomenon of market phase transition than the investor type.

  1. The veining phenomenon in unalloyed plutonium

    1976-01-01

    An investigation has been made of the veining phenomenon in unalloyed plutonium. The surface markings, or veins, which are sometimes seen on α-phase plutonium samples, arise as a result of the β→α transformation. As far as is known, this veining is unrivalled in its scale and form as compared with the solid state surface transformation effects shown by any other metal. The phenomenon has been explained by the application of the Le Chatelier principle to the phase change. In this instance, the large (10%) volume contraction associated with the β→α reaction and the anisotropy of the nonoclinic α-phase structure, account for the fact that the veins are so prominent in plutonium. On the basis of the proposed model, the veins can only form at temperatures where the transformation mechanism is non-martensitic. (Auth.)

    Full Text Available Migration is not a new phenomenon, neither for Europe, nor for the entire world and it exists since the beginning of mankind. Over time, this kind of international mobility generated many opportunities, but many challenges as well. Being an extremely important and complex phenomenon, both in economic terms and mostly from the social perspective, mass emigration has never been more intense as nowadays. Together with this particular complexity, the intensity of the migration phenomenon reveals each individual’s profound freedom desire, but also the acute need to ensure a better future for himself and especially for his family. Currently, an ever increasing number of individuals migrate in search of a better place, changing regions, countries or even continents. Witnessing the events that transcend the people all around the world, we consider that migration generates economic, social and cultural, but also political profound changes. These major changes require the involvement of the political actors, namely the governments, in creating a favorable and reliable framework so as the society and decision makers to understand that immigrants represent an opportunity for the emerging economies and not a phenomenon that should be criticized. In this paper we aim to follow the theories regarding the migration process, as well as the changes it generates, taking into consideration that of the 507 million current inhabitants of the EU, approximately 20 million are from countries outside the EU. We consider this research to be underlain, taking into consideration that regardless of the form it takes, in Europe immigration is and will remain a difficult to manage reality.

    Full Text Available Political actionism is the fenomen in social and art space, that appeared in middle of XX century as the practice of critic and protest with using different artistic methods and techniques. Political actionism as art and political tradition exist in postsoviet space, especially in Russia where actionism appeared in 1990 years and develops for actually days. In other countries this phenomenon not such systematic.  But analyze and compare actions in different countries appears the possibility to understand social and cultural context, their difference and similarity. Actionism is a reaction to external public, social and political situation, but its appearance more like the symptom of some problem than its critic or display – traditional approaches in art.  Appearance of actionism also connected with inability of manifestation of personal and civil liberty, that’s why in actions liberty affairs in such radical and hyperbolized forms. First volume of Russian political actionism began in 1990 years (Oleg Kulik, Alexander Brener, Anatoly Osmolovsky etc. and Second volume in 2010 (art-group Voina, Pussy Riot, Pyotr Pavlensky. This process not only a transformation of artistic and traditional space, but also modification of reaction on social and political situation. Actionism becomes a source of new type of knowledge, that give a possibility to see the habitual reality from another side and find in it new pointes and concepts. Political actionism contracting own interpretation of already well-established phenomenon. Usual concepts of liberty, authority, social control are deconstructed in actions. Those destructions of reality and cultural reorientation destroys traditional imposed patterns of interaction and social structure. But new views, that appeared in daily life from actions, often has mistaken interpretations. Exist a problem about identification of actions, its correct interpretations and understanding of its causes. In article was

    The overshoot phenomenon is a common occurrence in numerical software when a continuous function on a finite dimensional discretized space is used to approximate a discontinuous jump, in temperature and material concentration, for example. The resulting solution overshoots, and undershoots, the discontinuous jump. Numerical simulations play an extremely important role in mantle convection research. This is both due to the strong temperature and stress dependence of viscosity and also due to the inaccessibility of deep earth. Under these circumstances, it is essential that mantle convection simulations be extremely accurate and reliable. CitcomS and ASPECT are two finite element based mantle convection simulations developed and maintained by the Computational Infrastructure for Geodynamics. CitcomS is a finite element based mantle convection code that is designed to run on multiple high-performance computing platforms. ASPECT, an adaptive mesh refinement (AMR) code built on the Deal.II library, is also a finite element based mantle convection code that scales well on various HPC platforms. CitcomS and ASPECT both exhibit the overshoot phenomenon. One attempt at controlling the overshoot uses the Entropy Viscosity method, which introduces an artificial diffusion term in the energy equation of mantle convection. This artificial diffusion term is small where the temperature field is smooth. We present results from CitcomS and ASPECT that quantify the effect of the Entropy Viscosity method in reducing the overshoot phenomenon. In the discontinuous Galerkin (DG) finite element method, the test functions used in the method are continuous within each element but are discontinuous across inter-element boundaries. The solution space in the DG method is discontinuous. FEniCS is a collection of free software tools that automate the solution of differential equations using finite element methods. In this work we also present results from a finite element mantle convection

  8. Nothingness and the placebo effect phenomenon

    DEFF Research Database (Denmark)

    Jensen, Tine

    The placebo effect is a pharmacological conundrum, since it is a medical effect that is produced by “nothing” because no pharmacologically active substance is present in placebo. Placebo has, among other things, been defined as an inert substance, often a calcium pill. Simultaneously it presents...... a posthuman angle, applying Karen Barad’s concept of agential realism to tackle the issue of nothingness. I argue that the placebo effect produces specific agencies in the placebo effect phenomenon – that is, both the subject under treatment and the placebo emerge in the placebo effect in the act of measuring it...

    A review is given of ideas about magnetic monopoles. Attention is drawn to the still unexplained observations of Schein, Haskin and Glasser (1954), in which electron-positron pairs were produced in large numbers by a cosmic-ray interaction. Their experiment has been simulated in 300 GeV pN interactions at Fermilab, giving a production limit of 10 -7 per proton interaction. The explanation for this phenomenon may lie in magnetic monopoles, or it may be similar to that invoked to explain the so-called Centauro events. (A.W.)

    A 75 years old white male, for 3 years on treatment for virchowian hanseniasis, was admitted with active HD lesions, infiltration on the base of right lung, leg ulcer and malaise. After two days he developed purpura and hemorrhagic blisters in the limbs. The biopsy of these lesions revealed Lucio phenomenon. The patient worsened with mental confusion, psychomotor agitation and anisocoric pupils. In the 18th day of internation the patient died. Necropsy revealed virchowian infiltration plenty of bacilli in the skin and viscera as well as tuberculoid granuloma with acid-fast bacilli in the liver, spleen and bone marrow. These findings lead us to review the patient's classification from virchowian to borderline. In the lungs, leptomeninge, renal papile, prostate and thyroid it was found loose tuberculoid granuloma with a great amount of fungi surrounded by a gelly halo resembling Criptococcus neoformans. These findings and the onset of Lucio phenomenon are discussed in a patient that has been treated for 3 years and still having several virchowian lesions and a great amount of acid-fast bacilli.

    To evaluate the characteristic color doppler imaging of vertebral artery flow in the subclavian steal phenomenon. The study group consisted of eight patients with reversed vertebral artery flow proved by color Doppler imaging. We classified this flow into two groups:(1) complete reversal;(2) partial reversal, as shown by Doppler velocity waveform. Vertebral angiography was performed in six of eight patients;color Doppler imaging and angiographic findings were compared. On color Doppler imaging, all eight cases with reversed vertebral artery flow showed no signal at the proximal subclavian or brachiocephalic artery. We confirmed shunting of six cases by performing angiography from the contralateral vertebral and basilar artery to the ipsilateral vertebral artery. On the Doppler spectrum, six cases showed complete reversal and two partial reversal. On angiography, one partial reversal case showed complete occlusion of the subclavian artery with abundant collateral circulation of muscular branches of the vertebral artery. On color Doppler imaging, a reversed vertebral artery suggests the subclavian steal phenomenon. In particular, partial reversal waveform may reflect collateral circulation

    Full Text Available Children’s attribution of emotions to a moral transgressor is an important research topic in the psychology of moral and emotional development. This is especially because of the so-called Happy Victimizer Phenomenon (HVP where younger children attribute positive emotions to a moral transgressor described in a story. In the two studies that we have conducted (children aged 5, 7 and 9, 20 of each age; 10 of each age in the second study we have tested the possible influence of the fear of sanctions and the type of transgression (stealing and inflicting body injuries on the attribution of emotions. Children were presented with stories that described transgressions and they were asked to answer how the transgressor felt. The fear of sanctions did not make a significant difference in attribution but the type of transgression did - more negative emotions were attributed for inflicting body injuries than for stealing. Positive emotions were explained with situational-instrumental explanations in 84% of cases while negative emotions were explained with moral explanations in 63,5%. Girls attributed more positive emotions (61% than boys (39%. However, our main finding was that, for the aforementioned age groups, we did not find the HVP effect although it has regularly been registered in foreign studies. This finding denies the generalizability of the phenomenon and points to the significance of disciplining styles and, even more so, culture for children’s attribution of emotions to moral transgressors.

    After the broad industrialization of the US pork industry, there has been a development of niche markets for export and domestic pork; that is, there is a pork niche market phenomenon. The US pork niche market phenomenon is characterized, and 2 of the major markets are explained in detail. With the Midwest's tradition of a diversified family-based agriculture and record low hog prices of the late 1990s, the conditions were conducive for this phenomenon to develop. Pork niche markets utilize various sales methods including Internet sales, local abattoir sales, direct marketing, farmer networks, and targeting to organized groups. In 2003, there were approximately 35 to 40 active pork niche marketing efforts in Iowa. The Berkshire breed is an example of a swine breed that has had a recent resurgence because of niche markets. Berkshire pork is known for tenderness and excellent quality. Berkshire registrations have increased 4-fold in the last 10 yr. One of the larger niche marketers of "natural pork" is Niman Ranch Pork, which has more than 400 farmer-producers and processes about 2,500 pigs weekly. Many US consumers of pork are interested in issues concerning the environment, food safety, pig welfare, and pig farm ownership and structure. These consumers may be willing to pay more for pork from farmers who are also concerned about these issues. Small- and medium-sized swine farmers are active in pork niche markets. Niche markets claim product differentiation by superior or unique product quality and social attributes. Quality attributes include certain swine breeds, and meat quality, freshness, taste or flavor, and tenderness. Social or credence attributes often are claimed and include freedom from antibiotics and growth promotants; local family farm production; natural, organic, outdoor, or bedded rearing; humane rearing; known origin; environmentally friendly production; and the absence of animal by-products in the feed.

    Full Text Available The phenomenon of uncertainty in illness of patients is discussed and analyzed in this article. Uncertainty in illness is a condition that accompanies the patient from the moment of appearance of the first somatic symptoms of the disease and could be strengthened or weakened thanks to many psychosocial factors. The level of uncertainty is related to the level of stress, emotional disadaptation, affective states, coping strategies, mechanisms of psychological defense, etc. Uncertainty can perform destructive functions, acting as a trigger for stressful conditions and launching negative emotional experiences. As a positive function of uncertainty, one can note a possible positive interpretation of the patient's disease. In addition, the state of uncertainty allows the patient to activate the resources of coping with the disease, among which the leading role belongs to social support.

    Full Text Available Hybrid war is a reality; war does not depend only on conventional means, but includes communication and propaganda strategies whose role is increasingly important. In the last few years, terrorist cells have spent and keep spending many energies in a global propaganda business. This activity is a fundamental aspect of the conflict. This promotion campaign serves several purposes: legitimating its authority, recruiting militants and motivating sympathizers, and intimidating and conditioning those whose cells they consider enemies. What draws our attention is the sophisticated level of professionalism they demonstrate in managing propaganda and terror. This paper seeks to provide a broader view of the European Foreign Fighters (FF phenomenon by analyzing this target group from a marketing point of view in order to lay the foundations for a strategy to counteract them.

    1981-03-01

    The work on annealing of displacement damage, dissolution of boron precipitates, and the broadening of dopant profiles in semiconductors after treating with ruby and dye laser pulses is reviewed in order to provide convincing evidence for the melting phenomenon and illustrate the mechanism associated with laser annealing. The nature of the solid-liquid interface and the interface instability during rapid solidification is considered in detail. It is shown that solute concentrations after pulsed laser annealing can far exceed retrograde maxima values. However, there is a critical solute concentration above which a planar solid-liquid interface becomes unstable and breaks into a cellular structure. The solute concentrations and cell sizes associated with this instability are calculated using a perturbation theory, and compared with experimental results

    Déjà vu (DV, from French "already seen") is an aberration of psychic activity associated with transitory erroneous perception of novel circumstances, objects, or people as already known. An aim of the study was to investigate EEG characteristics of DV in patients with epilepsy. We studied 166 people (63.2% women, mean age 25.17±9.19 years). The DV phenomenon was studied in patients (27 people) and in a control group (139 healthy people). Patients were interviewed for DV characteristics and underwent a long (12-16 h) ambulatory EEG-monitoring study. In EEG, DV episodes in patients began with polyspike activity in the right temporal lobe and, in some cases, ended with the slow-wave theta-delta activity in the right hemisphere.

  3. Prussian phenomenon and its historical distortion

    Directory of Open Access Journals (Sweden)

    Oleg Y. Plenkov

    2016-03-01

    Full Text Available The article deals with the phenomenon of Prussia. Once, Prussia had been the largest continental Protestant state in Europe. The main issue of this phenomenon is that upon the tragic events of the World War II Prussian history and heritage had been considerably distorted, in order to compensate somehow for the dreadful casualties suffered by the victorious powers. The common European misconception implied that Prussia had been the bulwark of militarism, and therefore had to bear all the responsibility for the atrocities of war. Unfortunately, the majority of modern German historians share such misinterpretation of Prussian heritage in order to please false political correctness, perhaps, as an act of contrition for National Socialism and its crimes. However, the Prussian tradition and history go far beyond this militarism, and this article explains what ways. The authors believe that there should not be any prejudices and biases, that any subject should be examined sine ira et studio. Moreover, given that it is possible to characterize the Great French Revolution as a juristic one, and the Great October revolution – as a social one, the Prussian revolution “from above”, led by the first representatives of the Hohenzollern family, may be well considered as a pedagogical revolution. This revolution did bring definitely positive changes; they are surveyed in the article. The French Revolution has not eliminated the covetousness of the bourgeoisie after 1789; despotism of the authorities and people’s passiveness similarly have remained unaltered in Russia after 1917. On the contrary, Federal Republic of Germany of nowadays, distinctive for its law, order and effective responsible government is unthinkable without Prussian heritage.

  5. Priming intelligent behavior: an elusive phenomenon.

    Directory of Open Access Journals (Sweden)

    David R Shanks

    Full Text Available Can behavior be unconsciously primed via the activation of attitudes, stereotypes, or other concepts? A number of studies have suggested that such priming effects can occur, and a prominent illustration is the claim that individuals' accuracy in answering general knowledge questions can be influenced by activating intelligence-related concepts such as professor or soccer hooligan. In 9 experiments with 475 participants we employed the procedures used in these studies, as well as a number of variants of those procedures, in an attempt to obtain this intelligence priming effect. None of the experiments obtained the effect, although financial incentives did boost performance. A Bayesian analysis reveals considerable evidential support for the null hypothesis. The results conform to the pattern typically obtained in word priming experiments in which priming is very narrow in its generalization and unconscious (subliminal influences, if they occur at all, are extremely short-lived. We encourage others to explore the circumstances in which this phenomenon might be obtained.

    The informal workers phenomenon on housing construction projects in Indonesia is different from workers in other sectors who would always request as permanent employees. Substantively, the informal workers are disinclined to be bound as permanent employees which different from the general labor paradigm. Hence, the objective of this study is to find out how the labour selection process, the factors that affected their performance, and the suitable wage system to achieve the target completion of housing construction project. The qualitative method is used to uncover and understand the meaning behind the phenomena (numina) of informal workers action and their influence on housing construction project which called phenomenological approach. Five informal workers and two project managers were selected as informants based on predetermined criteria with in-depth interviews. The results showed that the informal worker were more satisfied with the wage based on unit price while working in the housing construction project for the flexibility in working hours. In addition, the developer was also relieved because they only control the quality and the achievement of the project completion time which supported by informal worker leader. Therefore, these findings are beneficial for both of developer and government as policy maker to succeed the housing program in Indonesia.

Through an appeal to the past, its genesis is analyzed, as well as its significance in modern realities. The latter is viewed from both a social and a personal point of view. Comparing the number of supporters of virtual communication with the number of people of conservative views, conclusions are drawn about the tendency to depart from the usual communication. It allows to assert that the problem of the termination of live communication is relevant to this day. Inferences allow us to assert that the problem of replacing real communication is different. After looking at the positive consequences, the introduction of the mind into virtual reality, it is affirmed that there are good sides to this action. Through analysis, the causes of entering the World Wide Web are generated. In conclusion, the question is raised about the need for virtual reality in everyday life, its problems, as well as the prospects for development.

  8. The keloid phenomenon: progress toward a solution.

    Louw, Louise

    2007-01-01

    For centuries, keloids have been an enigma and despite considerable research to unravel this phenomenon no universally accepted treatment protocol currently exists. Historically, the etiology of keloids has been hypothesized by multiple different theories; however, a more contemporary view postulates a multifactoral basis for this disorder involving nutritional, biochemical, immunological, and genetic factors that play a role in this abnormal wound healing. Critical to the process of preventing or managing keloids is the need to locally control fibroblasts and their activities at the wound site. In recent years, considerable evidence has accumulated demonstrating the importance of fatty acids and bioactive lipids in health and disease, especially those involving inflammatory disorders or immune dysfunction. If hypertrophic scarring and keloid formation can be argued to have significant inflammatory histories, then it is possible to postulate a role for lipids in their etiology and potentially in their treatment. This report briefly visits past views and theories on keloid formation and treatment, and offers a theoretical rationale for considering adjuvant fatty acid therapy for keloid management. Sufficient scientific evidence in support of fatty acid strategies for the prevention and treatment of keloids currently exists, which offer opportunities to bridge the gap between the laboratory and the clinic. The intent of this paper is to serve as a basic guideline for researchers, nutritionists, and clinicians interested in keloids and to propose new directions for keloid management.

    Wu, G. Z.; Zhou, C. T.; Fu, L. B.

    2018-01-01

    In this paper, we study the Klein tunneling phenomenon with electron-positron pair creation process. Pairs can be created from the vacuum by a supercritical single-well potential (for electrons). In the time region, the time-dependent growth pattern of the created pairs can be characterized by four distinct regimes which can be considered as four different statuses of the single well. We find that if positrons penetrate the single well by Klein tunneling in different statuses, the total number of the tunneling positrons will be different. If Klein tunneling begins at the initial stage of the first status i.e. when the sing well is empty, the tunneling process and the total number of tunneling positrons are similar to the traditional Klein tunneling case without considering the pair creation process. As the tunneling begins later, the total tunneling positron number increases. The number will finally settle to an asymptotic value when the tunneling begins later than the settling-down time t s of the single well which has been defined in this paper.

    One of the adverse effects arising among young people who engage in various social practices is the phenomenon of sexting. Sexting involves the production and delivery of sexual content voluntarily and freely and, in many cases, without the consent of the recipient. The aim of this study was to describe the presence of sexting in undergraduate students at the College of Nursing of the University of Almeria in Spain. It is a descriptive cross-sectional quantitative study. A total of 105 undergraduate nursing students completed the sexuality and technology questionnaire. The questionnaire consists of seven dimensions with 59 items. Depending on size, statistically significant differences between the use of social networks and the dimension "sexting actions completed" and the dimension "position on statements about sexting" were found. No statistically significant differences between gender and the practice of sexting were found. The three main reasons for sexting match in both genders, these being "to draw attention," "as a sexy gift," and "to feel sexy." Nursing students associated behaviors to show sexting, being a standard practice, common in both genders. Future research should consider the possible influence of this behavior on future professionals and on the field of nursing.

    Full Text Available The article is devoted to the problem of outsidership in groups of younger and older adolescents. We assumed that there are personal qualities that distinguish outsiders from other students, which allows us to speak of outsidership as a separate group and personal phenomenon. The study involved 246 students of Moscow schools of younger and older adolescents, 60 of whom took an outsider position in the group. To test the hypothesis were used: a personal questionnaire for adolescents HSPQ (R. Cattell, questionnaire Emin to determine the level of emotional intelligence (D.V. Lyusin, the technique of " Suggestibility " (O.E. Rybakov. To identify statistical differences, the Student's t-test and the Mann-Whitney U-test were used, p ≤ 0.05. The results of the study showed that outsiders of adolescence are indeed characterized by a number of personal characteristics that distinguish them from their peers. Differences in personal characteristics of outsiders at different stages of adolescence have their own characteristics.

  12. Lung tissue mechanics as an emergent phenomenon.

    Suki, Béla; Bates, Jason H T

    2011-04-01

    The mechanical properties of lung parenchymal tissue are both elastic and dissipative, as well as being highly nonlinear. These properties cannot be fully understood, however, in terms of the individual constituents of the tissue. Rather, the mechanical behavior of lung tissue emerges as a macroscopic phenomenon from the interactions of its microscopic components in a way that is neither intuitive nor easily understood. In this review, we first consider the quasi-static mechanical behavior of lung tissue and discuss computational models that show how smooth nonlinear stress-strain behavior can arise through a percolation-like process in which the sequential recruitment of collagen fibers with increasing strain causes them to progressively take over the load-bearing role from elastin. We also show how the concept of percolation can be used to link the pathologic progression of parenchymal disease at the micro scale to physiological symptoms at the macro scale. We then examine the dynamic mechanical behavior of lung tissue, which invokes the notion of tissue resistance. Although usually modeled phenomenologically in terms of collections of springs and dashpots, lung tissue viscoelasticity again can be seen to reflect various types of complex dynamic interactions at the molecular level. Finally, we discuss the inevitability of why lung tissue mechanics need to be complex.

    Full Text Available The present study aims to analyze the accounting professionals’ point of view as opposed to the students and master students’ one, regarding the creative accounting phenomenon existence and manifestation forms. In order to accomplish this objective, there has been used the poll/investigation, as a research method and the questionnaire, as a research instrument. Within the study, there is suggested the testing of more hypotheses that contribute to the clarifying of the aspects wished to be analyzed through the research. These hypotheses’ acceptance or rejection is based on the „chi-square“ (Karl Pearson statistical test and rank ordering method. Trying to elaborate a global conclusion of the questionnaire, there could be noticed the fact that over 50% from the questioned accounting students are not tempted to use the creative accounting practices and techniques in order to optimize the taxation without breaking the actual law regulations. At the opposite side, more than a half from the questioned accounting professionals would use these practices without breaking the law regulations that lead to the taxation’s optimization. The creative accounting has a negative connotation if the accurate image of the financial position and of the performance is not targeted because it represents the essential factor for elaborating and grounding the accounting policies. However, the positive side of the creative accounting is not excluded, given that one appeals to the „fair“ professional judgment of the accounting professionals and to the good faith of managers.

    Full Text Available This research mapped the phenomena that occured in students who are taking classes entrepreneurship that was limited by entrepreneurial knowledge, personal attitude, social norms and self-efficacy. Using descriptive statistics on the answers of 794 respondents, who were students of Bina Nusantara University, produced a variety of results. Based on entrepreneurial knowledge, students still felt hesitant to be able to start and run the entrepreneurial process. On the other hand, self-efficacy and personal attitude reflect a positive thing associated, while the support of family and the environment around where they livevalued invariety. Although this research discovered phenomenon using all the attributes having impacts on entrepreneurship intention, potential students who are properly trained have a probability of playing a leading role in this regard. The benefits that can be expected from this research are useful in identifying suitable students for any entrepreneurial activity in the future with the support of educational institutions, families, and the government as a whole to form the atmosphere of an entrepreneurial culture.

  15. Evolution as a molecular cooperative phenomenon

    1991-06-01

    We discuss an hypothesis according to which microscopic mechanisms due to cooperation, at the molecular level, may have been key factors in the evolution of life on Earth. We view our hypothesis as a natural extension to the molecular level of viewing cooperation (symbiosis) as an evolutionary driving force; this does not restrict the interpretation of the evolutionary process to be the result of slow accumulation of mutations in the DNA. Some evidence supporting this hypothesis is discussed: (a) The Salam enhancement factor. This molecular phenomenon was recently introduced in order to understand the bases of the first unifying principle of biochemistry, namely that transcription of all known genes in prokaryotes, protists, metazoan, and metaphytes are translated into L-amino acids, except for some bacterial membrane proteins. (b) The role that cooperative phenomena may have played in the origin of evolution itself, i.e., in the resolution of Sagan's ultraviolet paradox. (c) The relationship between evolution and the constraints imposed by embryonic development. This is considered from the point of view of molecular cooperative phenomena. (author). Refs

    Can behavior be unconsciously primed via the activation of attitudes, stereotypes, or other concepts? A number of studies have suggested that such priming effects can occur, and a prominent illustration is the claim that individuals' accuracy in answering general knowledge questions can be influenced by activating intelligence-related concepts such as professor or soccer hooligan. In 9 experiments with 475 participants we employed the procedures used in these studies, as well as a number of variants of those procedures, in an attempt to obtain this intelligence priming effect. None of the experiments obtained the effect, although financial incentives did boost performance. A Bayesian analysis reveals considerable evidential support for the null hypothesis. The results conform to the pattern typically obtained in word priming experiments in which priming is very narrow in its generalization and unconscious (subliminal) influences, if they occur at all, are extremely short-lived. We encourage others to explore the circumstances in which this phenomenon might be obtained. PMID:23637732

    Vacuum phenomenon was induced inadvertently during radiographic examination of a metatarsophalangeal joint of a lame horse. The phenomenon was recreated in a sound horse when a metacarpophalangeal joint was radiographed in a stress-flexed position. Distraction of apposing articular surfaces may induce the vacuum phenomenon, which could result in misdiagnosis of an osteochondral defect or fracture

    Primary Raynaud's phenomenon may be insistent in patients under medical therapy, and intrauterine devices may be an unnoticed reason in these patients. Fluctuations in female sex hormone status were reported to be associated with the emergence of primary Raynaud's phenomenon symptoms. The use of intrauterine devices was not reported to be associated with Raynaud's phenomenon previously. Intrauterine device may stimulate vascular hyperactivity regarding hormonal or unknown mechanisms that result in Raynaud's phenomenon. We present a postmenopausal patient who complained of primary Raynaud's phenomenon symptoms and had recovery after the removal of her copper intrauterine device. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  19. Cognitive approach in studying of entrepreneur phenomenon

    2017-06-01

    Full Text Available The research indicates that there is no prospect of searching specific entrepreneurial traits that are necessary for conducting successful entrepreneurial activity. It is pointed on the impossibility to fully explain the negative state of domestic business exclusively by the influence of environmental factors. The paper points on the necessity of concentrating the scientific search on the cognitive features of personality, as factors that contribute to success of entrepreneurial activities. It is revealed that the decision-making process directed on problem-solving in entrepreneurial activity, from an entrepreneurial idea to obtaining an appropriate result, cannot be algorithmized. The author points out on the insufficiency of attempts to model cognitive processes of entrepreneurs, in which their cognitive activity is regarded as an information processing system that resembles a computer. The results obtained in the framework of the cognitive approach in studying the phenomenon of the entrepreneur are analyzed. Particular emphasis is placed on the features of heuristics and cognitive biases. It is stated that the high levels of uncertainty, novelty, time deficit, information overload and emotional tension facilitate influence of cognitive biases on the cognitive processes of the entrepreneur. The role of «availability heuristic», «anchoring and adjustment heuristic», «confirmation bias», «hindsight bias» and self-efficacy in making decisions about starting an entrepreneurial activity are considered. The article points to the role of «belief in the law of small numbers» and the illusion of control in establishing optimistic bias (overly positive self-esteem, excessive optimism about future plans and events that lead to reducing the subjective perception of entrepreneurial risk.

  20. Electron string phenomenon: physics and use

    2004-01-01

    Electron string phenomenon arises as a result of phase transition of a state of multiply reflected electron beam to this new discovered state of one component electron plasma and can be easily observed in the reflex mode of EBIS operation. The transition goes via a strong instability, which causes considerable electron energy spread, which in its turn suppresses the instability. Electron string state is a stationary state of hot pure electron plasma, which is heated by injected electron beam and cooled because of electron loses. Electron string is quiet in broad regions of experimental parameters, so that it is used for confinement and ionization of positive ions by electron impact to highly charge states similar to electron beams in EBIS. Application of electron strings instead of electron beams for ion production allows to save about 99% of electric power of electron beam and simultaneously to improve reliability of an ion source considerably. The JINR EBIS `Krion-2' in the string mode of operation is used for production of N7+, Ar16+ and Fe24+ ion beams and their acceleration to relativistic energies on the facility of the JINR super conducting one turn injection synchrotron `Nuklotron'. The tubular electron string possibly can exist and it is under study now theoretically and experiments are prepared now. Estimations show that a Tubular Electron String Ion Source (TESIS) could have up to three orders of magnitude higher ion output then a Linear one (LESIS). In frames of nuclear astrophysics electron strings can be used for research of fusion nuclear reactions at low energies in conditions when both beam and target nuclei do not carry orbital electrons. The project NARITA — Nuclear Astrophysics Researches in an Ion Trap Apparatus is proposed. Polarization effects also can be studied.

    The levels in 162 Gd were identified in spontaneous fission studies. Its transition energies are remarkably similar to those in 160 Gd. From that work, an analysis of yrast bands in even-even proton to neutron-rich Ba to Pb nuclei led to the discovery of a new phenomenon, shifted identical bands (SIB). SIBs are yrast bands in neighboring nuclei (a, b) with moments of inertia which are identical when shifted by a constant amount κ, so J 1a (1 + κ) = J 1b , from 2 + to 8 + and higher to 16 + . Out of over 700 comparisons, 55 SIBs were found from stable to the most neutron-rich Ce-W nuclei with |κ-bar| between 1.5% and 13%, where the spread in κ is less than ± 1%, and only four identical bands (κ-bar congruent with 0). As examples, we found for 158 Sm- 160 Gd, κ-bar (-3.2 +0.1 -0.2 )% (where the ± is the total spread in κ from -3.1 to -3.4); 156 Nd- 160 Gd, (-10.6 +0.4 -0.2 )%; 158 Sm- 160 Sm, (3.4 +0.5 -0.3 )%. The J 1 values were fitted to a variable moment of inertia model with parameters J 0 and C whose values correlate with the SIB J 1 values. The SIBs are not correlated either with deformation or with the N p N n product of the IBA model

    Despite strong indications of a high prevalence of weight-related stigmatization in individuals with obesity, limited attention has been given to the role of weight discrimination in examining the stigma obesity. Studies, up to date, rely on a limited basis of data sets and additional studies are needed to confirm the findings of previous studies. In particular, data for Europe are lacking, and are needed in light of a recent ruling of the European Court of Justice that addressed weight-based discrimination. The data were derived from a large representative telephone survey in Germany (n=3003). The dependent variable, weight-based discrimination, was assessed with a one-item question. The lifetime prevalence of weight discrimination across different sociodemographic variables was determined. Logistic regression models were used to assess the association of independent and dependent variables. A sub-group analysis was conducted analyzing all participants with a body mass index ⩾25 kg m(-)(2). The overall prevalence of weight-based discrimination was 7.3%. Large differences, however, were observed regarding weight status. In normal weight and overweight participants the prevalence was 5.6%, but this number doubled in participants with obesity class I (10.2%), and quadrupled in participants with obesity class II (18.7%) and underweight (19.7%). In participants with obesity class III, every third participant reported accounts of weight-based discrimination (38%). In regression models, after adjustment, the associations of weight status and female gender (odds ratio: 2.59, PDiscrimination seems to be an ubiquitary phenomenon at least for some groups that are at special risk, such as heavier individuals and women. Our findings therefore emphasize the need for research and intervention on weight discrimination among adults with obesity, including anti-discrimination legislation.

  4. The Trump phenomenon: An explanation from sociophysics

    Galam, Serge

    2017-04-01

    The Trump phenomenon is argued to depart from current populist rise in Europe. According to a model of opinion dynamics from sociophysics the machinery of Trump’s amazing success obeys well-defined counter-intuitive rules. Therefore, his success was in principle predictable from the start. The model uses local majority rule arguments and obeys a threshold dynamics. The associated tipping points are found to depend on the leading collective beliefs, cognitive biases and prejudices of the social group which undertakes the public debate. And here comes the open sesame of the Trump campaign, which develops along two successive steps. During a first moment, Trump’s statement produces a majority of voters against him. But at the same time, according to the model the shocking character of the statement modifies the prejudice balance. In case the prejudice is present even being frozen among voters, the tipping point is lowered at Trump’s benefit. Nevertheless, although the tipping point has been lowered by the activation of frozen prejudices it is instrumental to preserve enough support from openly prejudiced people to be above the threshold. Then, as infuriated voters launch intense debate, occurrence of ties will drive progressively hostile people to shift their voting intention without needing to endorse the statement which has infuriated them. The ongoing debate does drive towards a majority for Trump. The possible Trump victory at November Presidential election is discussed. In particular, the model shows that to eventually win the Presidential election, Trump must not modify his past shocking attitude but to appeal to a different spectrum of frozen prejudices, which are common to both Democrats and Republicans.

  5. Powerful Radio Burst Indicates New Astronomical Phenomenon

    Astronomers studying archival data from an Australian radio telescope have discovered a powerful, short-lived burst of radio waves that they say indicates an entirely new type of astronomical phenomenon. Region of Strong Radio Burst Visible-light (negative greyscale) and radio (contours) image of Small Magellanic Cloud and area where burst originated. CREDIT: Lorimer et al., NRAO/AUI/NSF Click on image for high-resolution file ( 114 KB) "This burst appears to have originated from the distant Universe and may have been produced by an exotic event such as the collision of two neutron stars or the death throes of an evaporating black hole," said Duncan Lorimer, Assistant Professor of Physics at West Virginia University (WVU) and the National Radio Astronomy Observatory (NRAO). The research team led by Lorimer consists of Matthew Bailes of Swinburne University in Australia, Maura McLaughlin of WVU and NRAO, David Narkevic of WVU, and Fronefield Crawford of Franklin and Marshall College in Lancaster, Pennsylvania. The astronomers announced their findings in the September 27 issue of the online journal Science Express. The startling discovery came as WVU undergraduate student David Narkevic re-analyzed data from observations of the Small Magellanic Cloud made by the 210-foot Parkes radio telescope in Australia. The data came from a survey of the Magellanic Clouds that included 480 hours of observations. "This survey had sought to discover new pulsars, and the data already had been searched for the type of pulsating signals they produce," Lorimer said. "We re-examined the data, looking for bursts that, unlike the usual ones from pulsars, are not periodic," he added. The survey had covered the Magellanic Clouds, a pair of small galaxies in orbit around our own Milky Way Galaxy. Some 200,000 light-years from Earth, the Magellanic Clouds are prominent features in the Southern sky. Ironically, the new discovery is not part of these galaxies, but rather is much more distant

  6. Moe fenomen. The Phenomenon of Fashion

    2012-06-01

    Full Text Available Since the last quarter of the 20th century, particularly after the “cultural turn”, the interest in fashion has been increasing in a variety of different disciplines. Fashion has begun to be investigated in many different contexts, using new theoretical approaches. Fashion can be regarded as a social phenomenon, a sign system, as art, myth, or the product of the fashion industry. The purpose of this article is not to provide a definition of fashion, but rather to raise the question of how to approach the experience of fashion analytically. The methodological issues discussed here emerged in the course of preparing for empirical research on fashion. The observations and comparisons that constitute the core of this article are the result of efforts to juxtapose different methods. The traditional history of fashion used a historical-epistemological strategy but, depending on how one defines culture, the meaning of fashion can also be analysed using methods based on different epistemological strategies. The phenomenological method elaborated by Edmund Husserl, which I have chosen for my analysis of the experience of fashion, defines culture through the experiential acts of individuals. Simply stated, phenomenology considers the world as it is given to us in our consciousness. What is most important for empirical research is that the phenomenological method makes it possible to study the structure of a concrete experience and to focus on the mechanisms of the subjective creation of meaning. Thus this article has two main foci: a theoretical analysis of how the experience of fashion can be analytically revealed using the phenomenological method, and a comparison of the phenomenological approach with methods based on other strategies. The analysis of descriptions in the first person makes it possible to highlight how experience has been constructed. People “see” fashion based on structures of meaning; when they describe their own experience

    To determine whether high altitude travel adversely affects mountain enthusiasts with Raynaud's phenomenon. Volunteers with Raynaud's phenomenon were recruited using announcements disseminated by organizations dedicated to climbing or wilderness travel and Internet discussion boards dedicated to mountain activities to complete an online, anonymous survey. Survey questions addressed demographic variables, aspects of their Raynaud's phenomenon, and features of their mountain activities. Respondents compared experiences with Raynaud's phenomenon between high (>2440 m; 8000 feet) and low elevations and rated agreement with statements concerning their disease and the effects of high altitude. One hundred forty-two people, 98% of whom had primary Raynaud's phenomenon, completed the questionnaire. Respondents spent 5 to 7 days per month at elevations above 2440 m and engaged in 5.4 +/- 2.0 different activities. Eighty-nine percent of respondents engaged in winter sports and only 22% reported changing their mountain activities because of Raynaud's phenomenon. Respondents reported a variety of tactics to prevent and treat Raynaud's attacks, but only 12% used prophylactic medications. Fifteen percent of respondents reported an episode of frostbite following a Raynaud's phenomenon attack at high altitude. There was considerable heterogeneity in participants' perceptions of the frequency, duration, and severity of attacks at high altitude compared to their home elevation. Motivated individuals with primary Raynaud's phenomenon, employing various prevention and treatment strategies, can engage in different activities, including winter sports, at altitudes above 2440 m. Frostbite may be common in this population at high altitude, and care must be taken to prevent its occurrence.

    A classification has been made of various types of stratification phenomenon during intravenous cholangiography. The stage of gallbladder opacification in the recumbent position has been classified as (I) mottled, (II) dendritic, (III) ring-like, and (IV) homogeneous. 'Dendritic' type of stratification phenomenon has never been reported in the literature to our knowledge. At 20 min following infusion of contrast material homogeneous opacification of the gallbladder was noticed in only 14% of patients. The others fell into types I, II or III of stratification phenomenon. In contrast, 87% of the opacified gallbladders were homogeneous on the after fatty meal film. It is therefore mandatory for diagnosis that either a 24 h film or a fatty meal film be taken to avoid the stratification phenomenon.

    Full Text Available The paper considers the process of localization of a pop cultural and musical phenomenon – rock ’n’ roll. My basic premise is that rock ’n’ roll as a global music genre can be perceived as local, and hence represents a recognizable identification element for the local population. In this case the label r ’n’ r pertain to the phenomenon of Belgrade "new wave" music, which was popular during the 1980’s. Based on the analysis of narratives from relevant documentary films, it is my intention to find out whether "new wave" was initially perceived as a local phenomenon, and what the means of constructing this image are, as well as what it is that gives this phenomenon local legitimacy and credibility.

    The diagnostic value of the vacuum phenomenon between the femoral head and the acetabulum, and time frame of its occurrence after application of traction is an important clinical question. The resulting arthrogram may outline the shape, location, and extent of cartilage lesions prior to arthroscopy of the hip joint. The presence, duration, and diagnostic information of the vacuum phenomenon were evaluated in 24 hips that underwent arthroscopy. The operative diagnosis was compared to the results of imaging studies and to findings obtained during a traction trial prior to arthroscopy. Indications for arthroscopy included avascular necrosis, labral tears, loose bodies, osteoarthrosis, and intractable hip pain. In 22 hips the vacuum phenomenon developed within 30 seconds after application of traction. The most important data obtained from the vacuum phenomenon was the location and extent of femoral head articular cartilage detachment and the presence of nonossified loose bodies. The vacuum phenomenon did not reveal labral or acetabular cartilage pathology in any of these patients. The vacuum phenomenon obtained during the trial of traction can add valuable information prior to hip arthroscopy. Femoral head articular cartilage detachment was best documented by this method. The hip arthroscopist should utilize this diagnostic window routinely prior to hip arthroscopy. PMID:24977068

    Full Text Available The purpose of the investigation was to study the clinical value of the deja vu phenomenon in healthy examinees as it may occur in healthy individuals, on the one hand, and is a symptom of a number of psychoneurological diseases, on the other. One hundred and twenty-nine subjects, mean age 25,2±4,4 years, were examined. All the examinees were questioned by the original questionnaire developed by the authors, which was to reveal the characteristics of the phenomenon, and the Cambridge depersonalization questionnaire; standard electroencephalography was also performed. The deja vu phenomenon was detected in 97% of the respondents. In healthy individuals, the phenomenon was most common at the age of 21-25 years; 52,2% experienced deja vu several times a year; 64,5% of the respondents reported the 10-sec state; 85% did not associate the occurrence of the phenomenon with any provoking factor; 66% perceived deja vu with a positive emotional tinge, and only 4% of the respondents were afraid of the onset of this phenomenon. These criteria may be used to rule out pathological deja vu

    The reaction to body and finger cooling was recorded in seven patients with relapse of primary Raynaud's phenomenon after sufficiently performed bilateral upper thoracic sympathectomy and for comparison in eight young women with primary Raynaud's phenomenon as well as in seven normal women. The forearm venous concentration of noradrenaline was lower and adrenaline concentration higher in the sympathectomized patients than in the other groups (p less than 0,05). Noradrenaline showed a significant increase during body cooling in normals and primary Raynaud's (p less than 0,05). There was no significant correlation between the vasoconstrictor response to cooling of a finger and the noradrenaline concentration probably due to the fact that skin vasoconstriction impeded release of noradrenaline from the skin. The relapse of Raynaud's phenomenon after surgically sufficient sympathectomy could not be treated by reserpine or alfa-adrenergic receptor blockers in two patients in whom this was tried.

  7. The role of ocean phenomenon in music compositions

    Science.gov (United States)

    Liu, Chi-Min

    2016-04-01

    This is a preliminarily interdisciplinary study for exploring the elements of ocean phenomenon appearing in some compositions of classical music. The so-called ocean phenomenon contain wave conditions, climate change, coastal landform, and other natural events around or over the sea. In some music compositions, it is apparent that natural phenomenon over the sea influence the composers' moods and the music pieces they composed. In this poster, some music compositions in the 19th and the early 20th centuries will be introduced to demonstrate the relation between ocean and music works. These works include Meeresstille by Schubert, Étude Op.25 No.12 by Chopin, Fingal's Cave Overture by Mendelssohn, Der Fliegende Holländer by Wagner and La Mer by Debussy. In addition, present idea may give a novel way for music teachers to elucidate the knowledge of ocean science in classes.

  8. Statistical Agent Based Modelization of the Phenomenon of Drug Abuse

    di Clemente, Riccardo; Pietronero, Luciano

    2012-07-01

    We introduce a statistical agent based model to describe the phenomenon of drug abuse and its dynamical evolution at the individual and global level. The agents are heterogeneous with respect to their intrinsic inclination to drugs, to their budget attitude and social environment. The various levels of drug use were inspired by the professional description of the phenomenon and this permits a direct comparison with all available data. We show that certain elements have a great importance to start the use of drugs, for example the rare events in the personal experiences which permit to overcame the barrier of drug use occasionally. The analysis of how the system reacts to perturbations is very important to understand its key elements and it provides strategies for effective policy making. The present model represents the first step of a realistic description of this phenomenon and can be easily generalized in various directions.

    1996-04-01

    The ferro-resonance is a resonance phenomenon involving the saturation of the magnetic core in transformers; in particular, it is generated by the energization of that equipment during a power system restoration. It exhibits classical periodic regimes, but also more complex ones, as harmonic, pseudo-periodic, even chaotic, which have been measured on site or during laboratory tests. The mathematical analysis of this phenomenon belongs to the theory of bifurcations; the use of a program solving non linear systems may lead to a better understanding of the observed overvoltages.

    We examine the two-phase phenomenon described by Plerou, Gopikrishnan, and Stanley (2003) [1] in the KOSPI 200 options market, one of the most liquid options markets in the world. By analysing a unique intraday dataset that contains information about investor type for each trade and quote, we find that the two-phase phenomenon is generated primarily by domestic individual investors, who are generally considered to be uninformed and noisy traders. In contrast, our empirical results indicate that trades by foreign institutions, who are generally considered informed and sophisticated investors, do not exhibit two-phase behaviour.

    2009-01-01

    The Stokes phenomenon refers to the emergence of jump discontinuities in asymptotic expansions at specific rays in the complex plane. This book presents a radical theory for the phenomenon by introducing the concept of regularization. Two methods of regularization, Borel summation and Mellin-Barnes regularization, are used to derive general expressions for the regularized values of asymptotic expansions throughout the complex plane. Though different, both yield identical values, which, where possible, agree with the original functions. Consequently, asymptotics has been elevated to a true disc

    2013-12-01

    Full Text Available Presenteeism, understood as being at work while ill, is not a new phenomenon. However, not long ago it has become an object of researchers' interest. Formerly, they focused mainly on absenteeism. In general, presenteesim is perceived as negative and very costly for employers. The majority of scientific studies refer to the problem of employees' productivity reduced due to their attending work despite being ill, but the knowledge about presenteeism's causes and effects (other than decreased productivity for both, the employee and the organisation, is still very limited. Especially in Poland there are very few scientific reports on this issue. However, the paper on presenteeism published recently (the 3/2013 issue of this Journal defined this phenomenon as a noneffective presence at work. The authors postulate to avoid pejorative connotation of this term by equating presenteeism with loss of productivity, and to separate this phenomenon from its possible negative and positive consequences. Thus, this paper aims at presenting current state of the art on this phenomenon, including such issues as definitional problems, measures and frequency of presenteeism, as well as its causes and consequences. In this paper presenteeism is presented in a wider perspective of its individual and contextual determinants. Med Pr 2013;64(6:847–861

    A siphon phenomenon or siphoning often refers to the movement of liquid from a higher elevation to a lower one through a tube in an inverted U shape (whose top is typically located above the liquid surface) under the action of gravity, and has been used in a variety of reallife applications such as a toilet bowl and a Greedy cup. However, liquid drainage due to siphoning sometimes needs to be prevented. For example, a siphon breaker, which is designed to limit the siphon effect by allowing the gas entrainment into a siphon line, is installed in order to maintain the pool water level above the reactor core when a loss of coolant accident (LOCA) occurs in an open-pool type research reactor. In this paper, we develop a theoretical model to predict the siphon breaking phenomenon. In this paper, a theoretical model to predict the siphon breaking phenomenon is developed. It is shown that the present model predicts well the fundamental features of the siphon breaking phenomenon and undershooting height

    Full Text Available Penelitian ini akan menguji apakah ketiadaan Allah dalam praktik akuntansi budaya barat merupakan sebuah kesalahan, yang mana budaya barat menggunakan agama Kristen Katolik Roma dan praktek akuntansi yang digunakan dalam penelitian ini adalah PSAK 46 tentang pajak tangguhan. Beberapa peneliti akuntansi menyatakan bahwa akuntansi yang ada mengakomodasi kapitalisme. Selain itu, beberapa peneliti juga mempertanyakan tidak adanya agama dalam akuntansi. Sedangkan agama harus dianggap sebagai perilaku manusia yang mendasari kekuasaan, sehingga budaya yang dapat dilihat sebagai pengaruh penting pada pengembangan kebijakan dan praktik akuntansi. Tidak adanya Allah dalam akuntansi selalu menyalahkan budaya barat sebagai penyebabnya. Artikel ini menunjukkan bahwa budaya barat sangat mendorong warganya untuk membayar pajak. Sementara aturan akuntansi yang diatur dalam PSAK 46 bahkan mengakomodasi perencanaan pajak yang bertujuan untuk meminimalkan pajak yang dibayarkan kepada Negara. Artikel ini memberi kita refleksi: apakah kita masih akan menyalahkan budaya barat sebagai penyebab tidak adanya Allah dalam Praktek Akuntansi? This study will examine whether is nonexistence of God in the accounting practice is western culture’s mistake, which western culture that will be used are the Roman Catholic religion and the accounting practices used in this study is PSAK 46 about deferred tax. Some accounting researchers stated that the existing accounting accommodate capitalism. Moreover, some researchers also questioned the absence of religion in accounting. Whereas religion should be considered as a power underlying human behavior, so that culture can be seen as an important influence on the development of accounting policies and practices. Nonexistence of God in accounting always blaming western culture as the cause. This article shows that the western culture strongly encourages its citizens to pay taxes. While the accounting rules contained in PSAK 46 even accommodate tax planning that aims to minimize taxes paid to the state. This article gives us a reflection: are we still going to blame the western culture as the cause of nonexistence of God in Accounting?

  3. Study on Boiling Heat Transfer Phenomenon in Micro-channels

    Energy Technology Data Exchange (ETDEWEB)

    Jeong, Namgyun [Inha Technical College, Incheon (Korea, Republic of)

    2017-09-15

    Recently, efficient heat dissipation has become necessary because of the miniaturization of devices, and research on boiling on micro-channels has attracted attention. However, in the case of micro-channels, the friction coefficient and heat transfer characteristics are different from those in macro-channels. This leads to large errors in the micro scale results, when compared to correlations derived from the macro scale. In addition, due to the complexity of the mechanism, the boiling phenomenon in micro-channels cannot be approached only by experimental and theoretical methods. Therefore, numerical methods should be utilized as well, to supplement these methods. However, most numerical studies have been conducted on macro-channels. In this study, we applied the lattice Boltzmann method, proposed as an alternative numerical tool to simulate the boiling phenomenon in the micro-channel, and predicted the bubble growth process in the channel.

    2014-03-18

    Tullio phenomenon refers to eye movements induced by sound.(1) This unusual examination finding may be seen in superior semicircular canal dehiscence (SSCD) syndrome.(2) This disorder is due to absent bone over the superior semicircular canal (figure). Patients complain of dizziness triggered by loud sound, aural fullness, autophony, and pulsatile tinnitus. When Tullio phenomenon exists in SSCD syndrome, the patient develops a mixed vertical-torsional nystagmus in which the slow phase rotates up and away from the affected ear (video on the Neurology® Web site at Neurology.org). This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

    Cupping therapy is a traditional Chinese medicine used to heal psoriasis. The Koebner phenomenon is the occurrence of psoriatic lesions at the site of cutaneous injury. To describe the first case of biopsy-proven cupping-induced localized psoriasis, an example of the Koebner phenomenon. The histopathology of the lesions is described. A brief review of the literature regarding cupping therapy and its efficacy are discussed. A 45-year-old Asian male presented himself to the dermatology clinic for further treatment of his psoriasis. Four unusually circular plaques on the lower back were discovered. Pathologic diagnosis revealed an early lesion of psoriasis. on further inquiry, the patient admitted to undergoing a recent "cupping" procedure in an attempt to cure his condition. The efficacy of cupping therapy is controversial, and psoriatic patients may develop localized psoriasis through koebnerization as a result of cupping therapy rather than achieve desirable therapeutic benefits. © 2014 Canadian Dermatology Association.

    Full Text Available The paper problematizes the understanding of the concept of tradition in the context of the world music phenomenon. Marketed as a hybrid music genre, from the perspective of anthropological theory, the world music genre is a complex cultural phenomenon, the result of mixing global and local influences which are reflected not only in the creation of a specific sound, but through different perceptions of music itself (the audience, musicians, producers, creators of cultural policies etc. By analyzing the Serbian world music scene as exemplified by the work of the World Music association of Serbia, as well as the Serbia World Music Festival in Takovo, I will attempt to determine the way in which the concept of world music is perceived in local narratives, whether it is experienced as a form of musical tradition and if so, what is signified and represented as tradition in this context.

    Full Text Available The biology; especially the neurobiological features of the “love” phenomenon has recently started to attract attention. Love relations and attachment, which is closely related with them, are known to be important in health and disease. Love and love relations are found to be complex neurobiological phenomena based on activation of the limbic system of the brain. Those processes involve oxytocin, vasopressin, dopamine and serotonergic functions. Additionally, endorphine and endogenous opiate systems as well as nitrous oxide play role in those processes. The stages of love and love relations may demonstrate different neurochemical and neurophysiological features and may partially overlap with m aternal, romantic and sexual love and attachments. The aim of this article is to evaluate the common neurobiological pathways underlying the “love” phenomenon as well as their importance in medicine and health.

    Full Text Available We retrospectively reviewed the effectiveness of peripheral sympathectomy for severe Raynaud's phenomenon. In this study, a total of 14 digits from six patients with chronic digital ischemic change were included. All patients had pain, ulcer, or gangrenous change in the affected digits and were unresponsive to pharmacologic or other nonsurgical therapies. In all cases, angiography showed multifocal arterial lesions, so microvascular reconstruction was unfeasible. Peripheral sympathectomy was performed as a salvage procedure to prevent digit amputation. The results were analyzed according to reduction of pain, healing of ulcers, and prevention of amputation. In 12 of the 14 digits, the ulcers healed and amputation was avoided. In the other two digits, the ulcers improved and progressive gangrene was limited. As a salvage procedure for Raynaud's phenomenon recalcitrant to conservative treatment, peripheral sympathectomy improves perfusion to ischemic digits and enables amputation to be avoided.

    A vortex chamber is a simple device that separates compressed gas into a high-temperature stream and a low-temperature stream. It is increasing in popularity as a next-generation heat exchanger, but the flow physics associated with it is not yet well understood. In the present study, both experimental and numerical analyses were performed to investigate the temperature separation phenomenon inside the vortex chamber. Static pressures and temperatures were measured using high-sensitivity pressure transducers and thermocouples, respectively. Computational fluid dynamics was applied to simulate 3D unsteady compressible flows. The simulation results showed that the temperature separation is strongly dependent on the diameter of the vortex chamber and the supply pressure at the inlet ports, where the latter is closely related to the viscous work. The previous concept of a pressure gradient wave may not be a reasoning for temperature separation phenomenon inside the vortex chamber.

    Peripheral vascular abnormalities caused by a dysregulation between peripheral vasoconstriction and vasodilatation, clinically appearing with Raynaud's phenomenon, have been described in anorexia nervosa but specific characteristics of microcirculation in anorexic patients have not yet been studied. We performed nailfold videocapillaroscopy to assess microcirculatory alteration in anorexic patients and found three different patterns: normal, aspecific and early scleroderma pattern. We also evaluated several laboratory and clinical parameters to better assess our capillaroscopic findings. None of the clinical parameters examined correlated with specific capillaroscopic findings. An increased risk of autoimmune diseases in eating disorder patients has been described. Our results evidenced an association between early scleroderma capillaroscopic pattern and Raynaud's phenomenon that occurs in anorexia nervosa patients, whereas no significant association was found between all three capillaroscopic patterns and the presence of autoantibodies, as well as ESR and CRP values. Our study reveals that patients with AN suffering from RP exhibit NVC findings typical of connective tissue diseases.

    2007-01-01

    When a unit is tested outside a technical system, it has normally been removed due to a fault. However, in some cases the external test may not discover any fault and a No Fault Found (NFF) event may occur. The NFF phenomenon is a major problem when dealing with complex technical systems, and its consequences may be manifested in decreased safety and dependability and increased life cycle costs. There are multiple interacting causes of NFF, demanding tough requirements for successful solutions. The purpose of this paper is to describe the phenomenon of NFF and to highlight possible improvements for the prevention of causes of NFF and the reduction of its consequences. The study was performed as an explorative literature study, and the analysis was based on a holistic system view. The identified causes and solutions are related to life cycle stages, availability performance factors, and system stakeholders

    Full Text Available The paper describes the current state of the procrastination phenomenon in professional work, reviews the basic unexplored aspects in this area, and highlights the promising areas of scientific analysis. The survey of the existing literature periodization shows that the quantity of researches devoted to procrastination is growing exponentially every year. In spite of a pronounced research interest in this construct, in native and foreign psychological science procrastination phenomenon in the professional work is represented insufficiently. Firstly, there is no common and generally accepted definition of procrastination (Corkin, Yu, Lindt, 2011; Steel, 2010; Krause, Freund, 2014, that suggests that there is a deep terminological crisis in this area. Secondly, the characteristic of delaying the implementation of the elements of workload is represented only by the example of a fairly narrow range of professional activities, which makes it relevant to study the specificity of the differentiated functioning of the phenomenon on the material of a wide range of professions. Thirdly, in psychology there are no information about the peculiarities of the so-called “active” procrastination manifestations in professional activity, which is the tendency of conscious assignments delaying to achieve the optimum final result (Chu, Choi, 2005; Choi, Moran, 2009. Fourthly, there is an acute shortage of standardized psychodiagnostic tools to evaluate this phenomenon in work (most of the existing methods have been tested on samples of students and are aimed at identifying academic procrastination. In the fifth place, there are no science-based allocation of methods of coping with destructive manifestations of the psychological strategy of the job functions postponement in a professional work.

    The use of unlabeled samples in improving the performance of classifiers is studied. When the number of training samples is fixed and small, additional feature measurements may reduce the performance of a statistical classifier. It is shown that by using unlabeled samples, estimates of the parameters can be improved and therefore this phenomenon may be mitigated. Various methods for using unlabeled samples are reviewed and experimental results are provided.

  2. ACTIVITY-BASED ANOREXIA AS A THERMOREGULATION PHENOMENON

    Directory of Open Access Journals (Sweden)

    Carlos Javier Flores Aguirre

    2012-12-01

    Full Text Available Activity Based Anorexia (ABA is a phenomenon that results from exposing rats to a feeding program of about 1 to 1.5 h per day, giving them free access to an activity wheel the rest of the time. The reported effects are high levels of activity without a visible compensation in food intake, and in consequence a low body weight. There is a variety of interpretations about the causes of this phenomenon. However, there are two main theories: one of them says that ABA is a product of adaptive failure to the new feeding regime and that the activity in the wheel interferes with such adaptation. The second theoretical position says that the activity acquires reinforcing properties due to feeding restrictions which causes body weight loss and, in turn, more activity. At present, both theories have been interpreted as contradictory. Nevertheless, a series of studies have revealed that the temperature of the environment and in consequence the subjects’ body tem-perature play an essential role in the findings of the field, giving sense to both theories and evidencing their complementariness. The aim of this paper is to re-view the empirical evidence that supports the hypothesis of ABA as a thermoregu-lation phenomenon.

  3. The emerging magnetic flux and the elementary eruptive phenomenon

    International Nuclear Information System (INIS)

    Mouradian, Z.; Martres, M.J.; Soru-Escaut, I.

    1983-01-01

    Observational studies before and during the flare start were made in Hα(3-lambda heliograph at Meudon Observatory) on a large sample of ''elementary'' flares, both on the disk and along the limb of the Sun. The concept of elementary eruptive phenomenon (EEP) is proposed to describe these observational data. The EEP may be considered as the basic element of complex flares which, then, are built up by the juxtaposition of several EEP. In the inferred scenario, the chromospheric eruptive phenomenon consists of two systems of loops: one cold - the surging arch - Tapprox.=10 4 K, the other hot - the flaring arch -, covering a temperature range up to 10 7 K. The footpoints of the two systems remain differentiated until extinction of the phenomenon; their behaviour over time differs also. The surging arch (the magnetic flux emergence) rises first progressively in the solar atmosphere and the upper part of the loop is heated to coronal temperatures. The classical surge which is observed in the center of the Hα line, after the flash phase of the flare, is only the late development of the surging arch. The flaring arch originates from a pre-existing low loop, which is also to rise in the solar atmosphere. These two systems coexist and may combine to form such physical characteristics as mass motion, expansion and post-flash phase. (orig.)

    2012-10-01

    The aim of this work is to investigate the facial distortion (dysmorphopsia) experienced by patients with homonymous paracentral scotomas and to analyze the interrelationship with the previously described "thin man" phenomenon. Routine neuro-ophthalmological examination and brain MRI in three patients who suffered from small homonymous paracentral scotomas due to infarction or arteriovenous malformations of the occipital lobe. They all complained of distortion and shrinkage of their interlocutor's face contralateral to the brain lesion. The phenomenon appeared some seconds after steady fixation on the interlocutor's nose and was evident with both left and right homonymous scotomas. The patients did not notice a gap in the area corresponding to the scotoma and objects other than faces were perceived normally. Homonymous paracentral scotomas can lead to focal displacement of facial features towards the center of the field defect with resulting distortion of the face on the affected side. This so-called "dysmorphopsia" makes faces appear regionally narrower than they are in reality and may be induced even by visual field defects that remain undetected by conventional perimetry using 6° × 6° grids. Predilection for faces is probably associated with the superior location of scotomas or specific impairment of face processing abilities related to the lesion site. Facial dysmorphopsia is most probably associated with cortical "filling-in" and spatial distortion, and can hence be regarded as a special entity of the "thin man" phenomenon.

    Development of the phenomenon of cavitation in cavitation behavior requires knowledge of both plant and equipment working in the facility. This paper presents a diagram of cavitational behavior for a butterfly valve with a diameter of 100 mm at various openings, which was experimentally built. We proposed seven stages of evolution of the phenomenon of cavitation in the case of a butterfly valve. All these phases are characterized by pressure drop, noise and vibration at various flow rates and flow sections through the valve. The level of noise and vibration for the seven stages of development of the phenomenon of cavitation were measured simultaneously. The experimental measurements were comprised in a knowledge database used in training of a neural network of a neural flow controller that maintains flow rate constantly in the facility by changing the opening butterfly valve. A fuzzy position controller is used to access the valve open. This is the method proposed to provide operational supervision outside the cavitation for a butterfly valve.

    Full Text Available Summary. Raising of problem. The article notes that constructive denial of traditional beliefs is often a powerful source of scientific discoveries. However, the absence of a constructive negation of the diva phenomenon can not be perceived as a lack of an adequate interpretation of it. It is assumed that the interpretation of Diva phenomena can be based on the definition of the area of their existence, which is computationally irreducible within the boundaries of existing methods of identification. The definition of such an area initiates. The formation of hypotheses that interpret the assumptions about its existence. An example of the origin of one of the hypotheses is considered in this essay. Drawing on relativistic physics and cosmology, the authors put forward a hypothesis about the possibility of the existence of a parallel space-time continuum to the existing one. This allows us to assume the existence of fragments of diva-type phenomena shifted in time to the main such continuum. The presence of such a phenomenon allows one to assume a mental connection of the percipient to a parallel space-time continuum and to implement time-shifted predictions. As an example, the existence of a computationally irreducible region of a concrete psychophysical phenomenon (sculptural portraying is given.

  10. Life as a planetary phenomenon: the colonization of Mars

    1995-01-01

    Life is a planet-wide phenomenon in which its components incessantly move and interact. Life imperatively recycles its parts at the surface of the Earth in a chemical transformation and physical transport that depends utterly on the energy from a recent star, the Sun. Humanity, entirely dependent on other beings, plays a recent and relatively small part in the great phenomenon of life that transports and transforms the surface of the Earth. Our species accelerates but does not dominate the metabolism of the Earth system. Ironically, during the Apollo days of the sixties, fears were rampant that Martian or other extraterrestrial "germs" might "contaminate" our planet. After Viking, such fears are seen as the manifestation of cultural paranoia. The Viking missions complemented ground-based astronomical observation and yielded definitive evidence for the lack of life on the red planet. The Gaia hypothesis states that the surface temperature, composition of the reactive gases, oxidation state, alkalinity-acidity on today's Earth are kept homeorrhetically at values set by the sum of the activities of the current biota. Life, in other words, not only produces and maintains its immediate environment, but appears on Earth only as a planetary phenomenon. Since the natural tendency of all life is to grow exponentially to fill proximal volume, the question now "can life ecopoietically expand to Mars?" is entirely equivalent to the query of "can Gaia reproduce?".

  11. Simulation of the AC corona phenomenon with experimental validation

    Villa, Andrea; Barbieri, Luca; Marco, Gondola; Malgesini, Roberto; Leon-Garzon, Andres R

    2017-01-01

    The corona effect, and in particular the Trichel phenomenon, is an important aspect of plasma physics with many technical applications, such as pollution reduction, surface and medical treatments. This phenomenon is also associated with components used in the power industry where it is, in many cases, the source of electro-magnetic disturbance, noise and production of undesired chemically active species. Despite the power industry to date using mainly alternating current (AC) transmission, most of the studies related to the corona effect have been carried out with direct current (DC) sources. Therefore, there is technical interest in validating numerical codes capable of simulating the AC phenomenon. In this work we describe a set of partial differential equations that are comprehensive enough to reproduce the distinctive features of the corona in an AC regime. The model embeds some selectable chemical databases, comprising tens of chemical species and hundreds of reactions, the thermal dynamics of neutral species and photoionization. A large set of parameters—deduced from experiments and numerical estimations—are compared, to assess the effectiveness of the proposed approach. (paper)

  12. Phenomenon of primary and secondary extinction in textured material

    Kryshtab, T.G.; Palacios G, J.; Mazin, M.O.

    2002-01-01

    A new X-ray diffraction method is proposed for a more exact calculation of pole figures to determine the crystallite orientation distribution function (CODF) in textured materials, by the introduction of a correction of the integrated intensity of the diffracted beam due to the phenomenon of extinction. Besides, for the case of a symmetrical Bragg reflection from an ''infinitely thick'' flat parallel plate textured sample a simple solution is developed for the problem of separation and determination of primary and secondary extinction parameters, which can be present simultaneously. The determination of these parameters gives additional information about crystallite structure and allows us to evaluate the average subgrains size and their disorientation, respectively. In this work according to the dynamic diffraction theory, it is shown that the extinction length, which is directly connected with the phenomenon of primary extinction, in the Bragg geometry for σ polarization (perpendicular) is independent on the wavelength used for a given reflection. On the other hand, the additional contribution from secondary extinction depends on X-ray wavelength due to the change of effective absorption coefficient. Considering this fact, the calculations of pole density and the parameters of primary and secondary extinction are performed using the same strong reflection for two different wavelengths and, for one of these wavelengths, a second order of reflection. For confirmation of the proposed method a partially cold rolled aluminium sample and an aluminium powder standard sample were measured. The corrected pole densities, the values of primary and secondary extinction and the average sizes of perfect coherent areas and average angle of disorientation of subgrains in the selected directions were obtained. The obtained results show that the precise X-ray diffraction characterization of textured materials requires the consideration, in general, of primary as well as secondary

  13. The Hurst Phenomenon in Error Estimates Related to Atmospheric Turbulence

    Science.gov (United States)

    Dias, Nelson Luís; Crivellaro, Bianca Luhm; Chamecki, Marcelo

    2018-05-01

    The Hurst phenomenon is a well-known feature of long-range persistence first observed in hydrological and geophysical time series by E. Hurst in the 1950s. It has also been found in several cases in turbulence time series measured in the wind tunnel, the atmosphere, and in rivers. Here, we conduct a systematic investigation of the value of the Hurst coefficient H in atmospheric surface-layer data, and its impact on the estimation of random errors. We show that usually H > 0.5 , which implies the non-existence (in the statistical sense) of the integral time scale. Since the integral time scale is present in the Lumley-Panofsky equation for the estimation of random errors, this has important practical consequences. We estimated H in two principal ways: (1) with an extension of the recently proposed filtering method to estimate the random error (H_p ), and (2) with the classical rescaled range introduced by Hurst (H_R ). Other estimators were tried but were found less able to capture the statistical behaviour of the large scales of turbulence. Using data from three micrometeorological campaigns we found that both first- and second-order turbulence statistics display the Hurst phenomenon. Usually, H_R is larger than H_p for the same dataset, raising the question that one, or even both, of these estimators, may be biased. For the relative error, we found that the errors estimated with the approach adopted by us, that we call the relaxed filtering method, and that takes into account the occurrence of the Hurst phenomenon, are larger than both the filtering method and the classical Lumley-Panofsky estimates. Finally, we found that there is no apparent relationship between H and the Obukhov stability parameter. The relative errors, however, do show stability dependence, particularly in the case of the error of the kinematic momentum flux in unstable conditions, and that of the kinematic sensible heat flux in stable conditions.

  14. Modeling the Pineapple Express phenomenon via Multivariate Extreme Value Theory

    Science.gov (United States)

    Weller, G.; Cooley, D. S.

    2011-12-01

    The pineapple express (PE) phenomenon is responsible for producing extreme winter precipitation events in the coastal and mountainous regions of the western United States. Because the PE phenomenon is also associated with warm temperatures, the heavy precipitation and associated snowmelt can cause destructive flooding. In order to study impacts, it is important that regional climate models from NARCCAP are able to reproduce extreme precipitation events produced by PE. We define a daily precipitation quantity which captures the spatial extent and intensity of precipitation events produced by the PE phenomenon. We then use statistical extreme value theory to model the tail dependence of this quantity as seen in an observational data set and each of the six NARCCAP regional models driven by NCEP reanalysis. We find that most NCEP-driven NARCCAP models do exhibit tail dependence between daily model output and observations. Furthermore, we find that not all extreme precipitation events are pineapple express events, as identified by Dettinger et al. (2011). The synoptic-scale atmospheric processes that drive extreme precipitation events produced by PE have only recently begun to be examined. Much of the current work has focused on pattern recognition, rather than quantitative analysis. We use daily mean sea-level pressure (MSLP) fields from NCEP to develop a "pineapple express index" for extreme precipitation, which exhibits tail dependence with our observed precipitation quantity for pineapple express events. We build a statistical model that connects daily precipitation output from the WRFG model, daily MSLP fields from NCEP, and daily observed precipitation in the western US. Finally, we use this model to simulate future observed precipitation based on WRFG output driven by the CCSM model, and our pineapple express index derived from future CCSM output. Our aim is to use this model to develop a better understanding of the frequency and intensity of extreme

    1991-01-01

    This paper discusses valve design features which affect the ability to predict motor operated valve (MOV) performance and reviews factors which should be considered when selecting switch settings to limit stem loads. Considerable attention is given to the rate of loading phenomenon which affects the relationship between valve stem thrust and actuator spring pack deflection. Equations are developed, and testing is discussed which permit the construction of an MOV dynamic model. Factors which must be considered when maintaining switch settings correct throughout the life of the plant are discussed. And switch setting acceptance criteria for use with baseline Static and Design Basis testing are suggested

    Based on searching the combining of quadratic function and exponential (or hyperbolic cosine) function from the Hirota bilinear form of the dimensionally reduced p-gBKP equation, eight class of interaction solutions are derived via symbolic computation with Mathematica. The submergence phenomenon, presented to illustrate the dynamical features concerning these obtained solutions, is observed by three-dimensional plots and density plots with particular choices of the involved parameters between the exponential (or hyperbolic cosine) function and the quadratic function. It is proved that the interference between the two solitary waves is inelastic.

  3. Preventing Instability Phenomenon in Gas-lift Optimization

    2015-01-01

    Full Text Available One of the problems that sometimes occur in gas allocation optimization is instability phenomenon. This phenomenon reduces the oil production and damages downhole and surface facilities. Different works have studied the stability and suggested some solutions to override it, but most of them (such as making the well intelligent are very expensive and thus they are not applicable to many cases. In this paper, as a new approach, the stability has been studied in gas allocation optimization problems. To prevent the instability, instability has been assumed as a constraint for the optimizer and then the optimizer has been run. For the optimization, first a genetic algorithm and then a hybrid of genetic algorithm and Newton-Quasi have been used, and their results are compared to ensure the good performance of the optimizer; afterwards, the effect of adding the instability constraint to the problem on production reduction have been discussed. The results show that the production loss with adding this constraint to the system is very small and this method does not need any additional and expensive facilities for preventing the instability. Therefore, the new method is applicable to different problems.

    Full Text Available Raynaud’s phenomenon (RP is a common condition that predominantly occurs among women. The onset age in most cases is under 30 years. The phenomenon was first described by M. Raynaud over 150 years ago. Primary (Raynaud’s disease and secondary RP were subsequently distinguished. Pathophysiology of RP has not been fully elucidated yet; RP seems to be a multifactor disease. A pronounced vasospasm in response to stimuli is believed to be caused by disruption in the central and local mechanisms of regulation of vascular tonus. Vascular endothe- lial, intravascular, and neuronal disorders are the key ones among these factors. Structural changes in vessels that can be observed by nailfold capillaroscopy play a significant role in pathophysiology of secondary RP. The key step in the diagnosis of RP is identifying its clinical variant, since secondary RP may be a sign or a premonitory symptom of certain autoimmune, hematologic, endocrine, neoplastic, and other disorders. Secondary RP is most frequently observed in patients with systemic rheumatoid diseases. Therapy of secondary RP provides no satisfactory out- comes, since there is no complete conception about the pathophysiological mechanisms of its development. Different groups of drugs are cur- rently used to treat RP, including calcium channels blockers, phosphodiesterase type 5 inhibitors, endothelin receptor antagonists, etc. This review focuses on pathogenesis, the algorithm of early and differential diagnosis of RP, and current approaches to therapy based on the analysis of the published and our own data.

    Full Text Available As the phenomenon of abuse in the workplace came to a closer public eye of a broader audience through media coverage, there is not a more fertile ground for a fully detailed problem explanation and search for its short or long-term solution. The dose of seriousness concerning the issue of mobbing isn’t only given for its negative effect on a business organization, but also for the mutation of a society’s culture, as well. The research paper outlines the mobbing phenomenon by presenting the theoretical and practical (statistical diagnosis through which, for a better understanding of the situation, there are added testimonies of mobbing victims, as well as legal and extra-judicial solutions for the issue. The observation of the phenomena is focused on the research and data presentation, using examples from Serbia and Europe. Putting aside the obvious differences in approach, a great space for implementation of European developed countries’ principles can be seen. The same principles could be introduced on the domestic scene, with the introduction of mandatory work conditions that are considered decent.

  8. Discrete numerical investigation of the ratcheting phenomenon in granular materials

    2010-10-01

    Several relevant geotechnical works, such as railway and road embankments, offshore foundations and vibrating machine foundations, are affected by the progressive accumulation of irreversible settlements. These latter represent the macroscopic evidence of the progressive rearrangement of particles under cycling loading, which is commonly referred to, in the literature, as ratcheting. This phenomenon is well known, but it is quite difficult to describe it by means of an appropriate constitutive model. As a consequence, the evaluation of durability of the aforementioned structures remains an open problem. In this article, the phenomenon will be approached by employing a Distinct Element model capable of describing the evolution of the microstructure induced by cyclic mechanical perturbations. Several analyses are performed in order to stress the influence of both the stress level and loading history on the mechanical response of a numerical model of a sand specimen. The numerical analyses are intended to provide an experimental background for conceiving a simplified macro approach based on generalised plasticity theory. In particular by means of probe test the plastic potential and the hardening parameters will be defined as a function of the current stress state and loading history.

  9. Elephant's foot phenomenon in liquid storage tanks

    Chen, C.Q.

    1983-01-01

    This paper presents a method for analyzing the seismic response of a flat bottomed cylindrical liquid storage tank to vertical earthquake excitation. Here, vertical earthquake acceleration is considered to correspond to an increase in the density of a stored liquid. Taking into account the vertical and horizontal earthquake loads, hydrostatic pressure, and considering restrictive moment and shear forces at shell-bottom welded joint, the author has calculated circumferential and longitudinal stresses. These are combined to more accurately approximate the stresses at the base shell course. The calculated result closely conforms to the actual damage, termed ''elephant's foot,'' observed in the fuel storage tanks damaged in the Tangshan earthquake. This result shows that the ''elephant's foot'' phenomenon is not caused by buckling of the tank shell due to longitudinal compressive stresses resulting from horizontal earthquake acceleration, but rather by the combined stresses in the base shell course of the storage tank exceeding the yield strength of the shell course material. The effect due to vertical earthquake load is more than the effect from the horizontal load. Finally, some earthquake resistant methods to prevent the ''elephant's foot'' phenomenon are suggested by the author.

    Following up on earlier investigations, the present paper analyzes construct validity of the impostor phenomenon. It examines the question whether the impostor phenomenon is a homogeneous construct or whether different types of persons with impostor self-concept can be distinguished on the basis of related characteristics. The study was conducted with professionals in leadership positions exhibiting a pronounced impostor self-concept ( n = 183). Cluster-analytic procedures indicated the existence of two different types: one group which, in line with the literature (e.g., Clance, 1985), possessed traits classified as fairly unfavorable ("true impostors") and another group which can be described as largely unencumbered ("strategic impostors"). The present study suggests two types of impostorism: "True" impostors characterized by the negative self-views associated with the construct definition, and more "strategic" impostors who seem to be less encumbered by self-doubt. It is assumed that "strategic impostors" are characterized by a form of deliberate self-presentation. Therefore, the impostor self-concept cannot principally be viewed as a dysfunctional personality style. This distinction should be more carefully considered in further research and in therapeutic interventions.

    Concomitant tumor resistance (CR) is a phenomenon originally described in 1906 in which a tumor-bearing host is resistant to the growth of secondary tumor implants and metastasis. Although recent studies have indicated that T-cell-dependent processes mediate CR in hosts bearing immunogenic small tumors, manifestations of CR induced by immunogenic and nonimmunogenic large tumors have been associated with an elusive serum factor. In this study, we identify this serum factor as tyrosine in its meta and ortho isoforms. In three different murine models of cancer that generate CR, both meta-tyrosine and ortho-tyrosine inhibited tumor growth. In addition, we showed that both isoforms of tyrosine blocked metastasis in a fourth model that does not generate CR but is sensitive to CR induced by other tumors. Mechanistic studies showed that the antitumor effects of the tyrosine isoforms were mediated, in part, by early inhibition of mitogen-activated protein/extracellular signal-regulated kinase pathway and inactivation of STAT3, potentially driving tumor cells into a state of dormancy. By revealing a molecular basis for the classical phenomenon of CR, our findings may stimulate new generalized approaches to limit the development of metastases that arise after resection of primary tumors, an issue of pivotal importance to oncologists and their patients. ©2011 AACR

    The different stages leading to knowledge of the phenomenon of animal breathing are going from some writings in Corpus Hippocraticum to Aristoteles' and Galen's works, who considered the heart as the source of the animal heat. Later, Miguel Servet suggested that the inspired air can achieve other functions besides cooling the blood. After that, different explications of the animal heat were raised. About 1770, due to progress of knowledge in the chemistry field, first Mayow and later Black began to consider the animal respiration as a combustion. The important treatise Méthode de nomenclature chimique, published by Guyton de Morveau et al. in 1787 and soon after the Traité élémentaire de chimie de Lavoisier (1789) provided a solid support to Lavoisier's thought. This way on arrived to consider analogous the respiration and combustion phenomena. Studies on the animal respiration phenomenon continued in xix century and in the following century it was possible to apply thermodynamic principles to biology: "generalized thermodynamics".

  13. Effects of Forgetting Phenomenon on Surveillance Test Interval

    International Nuclear Information System (INIS)

    Lee, Ho-Joong; Jang, Seung-Cheol

    2007-01-01

    Technical Specifications (TS) requirements for nuclear power plants (NPPs) define Surveillance Requirements (SRs) to assure safety during operation. SRs include surveillance test intervals (STIs) and the optimization of the STIs is one of the main issues in risk-informed applications. Surveillance tests are required in NPPs to detect failures in standby equipment to assure their availability in an accident. However, operating experience of the plants suggests that, in addition to the beneficial effects of detecting latent faults, the tests also may have adverse effects on plant operation or equipment; e.g., plant transient caused by the test and wear-out of safety system equipment due to repeated testing. Recent studies have quantitatively evaluated both the beneficial and adverse effects of testing to decide on an acceptable test interval. The purpose of this research is to investigate the effects of forgetting phenomenon on STI. It is a fundamental human characteristic that a person engaged in a repetitive task will improve his performance over time. The learning phenomenon is observed by the decrease in operation time per unit as operators gain experience by performing additional tasks. However, once there is a break of sufficient length, forgetting starts to take place. In surveillance tests, the most common factor to determine the amount of forgetting is the length of STI, where the longer the STI, the greater the amount of forgetting

    Surface Plasmon Resonance (SPR) phenomenon of the insulating polyaniline (PANI) is has been observed. Surface Plasmon (SP) is the traveled electromagnetic wave that passes through the interface of dielectric metal and excited by attenuated total reflection (ATR) method in Kretschmannn configuration (Au-PANI prism). The resonance condition is observed through the angle of SPR in such condition that SP wave is coupled by the evanescent constant of laser beam. In this research, the laser beam was generated by He–Ne and its wavelength (λ) was 632,8 nm. SPR curve is obtained through observation of incidence angles of the laser beam in prism. SPR phenomenon at the boundary between Au – PANI layer has showed by reflection dip when the laser beam passes through the prism. In this early study, the observation was carried out through simulation Winspall 3.02 software and preliminary compared with some experimental data reported in other referred literatures. The results shows that the optimum layer of Au and polyaniline are 50 and 1,5 nm thick respectively. Our own near future experimental work would be further performed and reported elsewhere.

  15. The God effect quantum entanglement, science’s strangest phenomenon

    Clegg, Brian

    2006-01-01

    The phenomenon that Einstein thought too spooky and strange to be true What is entanglement? It's a connection between quantum particles, the building blocks of the universe. Once two particles are entangled, a change to one of them is reflected---instantly---in the other, be they in the same lab or light-years apart. So counterintuitive is this phenomenon and its implications that Einstein himself called it "spooky" and thought that it would lead to the downfall of quantum theory. Yet scientists have since discovered that quantum entanglement, the "God Effect," was one of Einstein's few---and perhaps one of his greatest---mistakes. What does it mean? The possibilities offered by a fuller understanding of the nature of entanglement read like something out of science fiction: communications devices that could span the stars, codes that cannot be broken, computers that dwarf today's machines in speed and power, teleportation, and more. In The God Effect, veteran science writer Brian Clegg has written an ex...

  16. THE GENERATING AND COMPLEMENTARY EFFECTS OF THE UNDERGROUND ECONOMY PHENOMENON

    Directory of Open Access Journals (Sweden)

    Corneliu Sorin BAICU

    2016-12-01

    Full Text Available For a comprehensive understanding of the informal sector, an analysis addressing the relationships and links between the morphology and etiology of the underground economy, on the one hand, and its effects on the economic, social or legal, on the other hand is required. The double identity, that of cause phenomenon and effect phenomenon, that the underground economy has, gives it a special status in explaining certain phenomena which vitiates the economic and social life. The generating and complementary effects of the underground area covered in this study are analyzed in terms of the following vectors of analysis: tax evasion, illegal work and money laundering. Tax evasion represents the central core of the underground economy and faithfully expresses the fiscal monetary policies ,the fiscal mortality and the degree of compliance of the taxpayer. Undeclared work is an indicator of the labor market in the informal economy and is a good barometer for analyzing the demand and supply of labor in the visible economy. Money laundering defines the level of economic and financial crime and reflects the level of illegal use of capital on the black market. Tax evasion, money laundering and illegal work can only develop on a framework provided by illicit markets for goods, services and labor. Beyond the, unidirectional or bidirectional relationships between phenomena, the paper consists in a plea for an interdependent, multi-causal analysis of the phenomena and operating mechanisms of the relationships within and outside the underground economy.

  17. The clinicide phenomenon: an exploration of medical murder.

    Science.gov (United States)

    Kaplan, Robert

    2007-08-01

    The aim of this paper is to explore the phenomenon of clinicide. The study of medical killers is barely in its infancy. Clinicide is the unnatural death of multiple patients in the course of treatment by a doctor. Serial medical killing is a relatively new phenomenon. The role model is Dr Marcel Petiot, the worst serial killer in French history. More recently, Dr Harold Shipman was Britain's worst serial killer and in the United States and Zimbabwe, Dr Michael Swango killed 60 patients. A number of doctors have such high patient death rates that it cannot be ignored. At some level, these doctors have an awareness of what they are doing, countered by an overweening refusal to acknowledge the implications or desist from further treatment. Treatment killer offences usually occur on the basis of serial mental illness, but may include the contentious area of euthanasia killing. Doctors have frequently been accomplices in state repression, brutality and genocide in direct contravention to their sanctioned role to relieve suffering and save life. They have become mass murderers on an exponential scale, making any comparison with a doctor killing his own patients almost risible. Many clinicidal doctors have extreme narcissistic personalities, a grandiose view of their own capability and inability to accept that they could be criticized or need assistance from other doctors. Such doctors develop a God-complex, getting a vicarious thrill out of ending suffering and by determining when a person dies.

    It has been reported that people tend to preferentially associate phonemes like /m/, /l/, /n/ to curvilinear shapes and phonemes like /t/, /z/, /r/, /k/ to rectilinear shapes. Here we evaluated the performance of children/adolescents with autism spectrum disorders (ASD) and neurotypical controls in this audiovisual congruency phenomenon. Pairs of visual patterns (curvilinear vs rectilinear) were presented to a group of ASD participants (low- or high-functioning) and a group of age-matched neurotypical controls. Participants were asked to associate each item to non-meaningful phoneme clusters. ASD participants showed a lower proportion of expected association responses than the controls. Within the ASD group the performance varied as a function of the severity of the symptomatology. These data suggest that children/adolescents with ASD show, although at different degrees as a function of the severity of the ASD, lower phonetic-iconic congruency response patterns than neurotypical controls, pointing to poorer multisensory integration capabilities.

    In this paper, we visualize plasma collision phenomenon based on XYT-space (space and time) volume data for supporting research in plasma physics. We create 3D volume data in the XYT-space by piling up a time series of XY-plane photo images taken in experiment. As a result, we can visualize as one still image all the time behavior of the plasma plume. Besides, we adopt 'fused' visualization based on particle based rendering technique. Using that technique, we can easily fuse volume rendering different materials, and compare physics of different elements in flexible ways. In addition, we propose the method to generate pseudo-3D images from pictures shoot by ICCD of two perspectives on the upper and side. (author)

  1. Violence against women: the phenomenon of workplace violence against nurses.

    Child, R J Howerton; Mentes, Janet C

    2010-02-01

    Registered nurses have been the recipients of an alarming increase in workplace violence (WPV). Emergency and psychiatric nurses have been found to be the most vulnerable and yet few solid reporting procedures exist to fully account for a true number of incidents. Further compounding the problem is the lack of a standard definition of violence to guide reporting procedures, interventions, legislation, and research. While there are certain risk factors that not only predispose the nurse and the patient to WPV, research continues to attempt to parse out which risk factors are the key determinants of WPV and also which interventions prove to be significant in reducing WPV. The nursing shortage is expected only to increase; recruitment and retention of qualified staff members may be deterred by WPV. This necessitates focused research on the phenomenon of workplace violence in health care.

    Full Text Available This paper presents analytical results of the study of adaptatiogenesis within the family Arvicolidae (Mammalia, Rodentia based of morphological changes of the most functional characters of their masticatory apparatus — dental system — through time. The main directions of the morphological differentiation in parallel evolution of the arvicolid tooth type within the Cricetidae and Arvicolidae during late Miocene and Pliocene were identified and substantiated. It is shown that such unique morphological structure as the arvicolid tooth type has provided a relatively high rate of evolution of voles and a wide range of their adaptive radiation, as well as has determined their taxonomic and ecological diversity. The optimality of the current state of this group and evaluation of evolutionary prospects of Arvicolidae were presented and substantiated here as a phenomenon in their evolution.

    1998-11-01

    Raynaud's phenomenon (RP) is a peripheral circulatory disorder characterized by sudden episodes of digital artery spasm, often precipitated by cold temperature or emotional stress. Although the cause of RP is not fully known, it appears to involve inappropriate adrenergic response to cold stimuli. Treatment of RP is conservative in most patients, but in patients with severe disease includes the use of agents that promote digital vasodilation. The calcium-channel antagonists, particularly the dihydropyridine derivative nifedipine, are the most thoroughly studied drug class for the treatment of RP. Approximately two thirds of patients respond favorably, with significant reductions in the frequency and severity of vasospastic attacks. Nifedipine use is often limited by the appearance of adverse vasodilatory effects such as headache or peripheral edema. The newer second-generation dihydropyridines such as amlodipine, isradipine, nicardipine, and felodipine also appear to be effective in patients with RP and may be associated with fewer adverse effects.

    A 57-year-old right-handed woman with a history of left frontal lobe stroke had experienced episodes of language-expression difficulty followed by paraphasia lasting for approximately 30 seconds two years earlier. She was diagnosed with left frontal lobe epilepsy, and a lamotrigine regimen was initiated. This treatment had to be stopped five weeks after initiation because she developed a rash, and her drug lymphocyte stimulation test result was positive. Interestingly, she has since remained seizure free without requiring any antiepileptic medications. This adult case with a peculiar clinical course provides support for the hypothesis of immunomodulation process involvement in epilepsy, a phenomenon that was previously mainly seen in pediatric patients.

    Controlled depolymerization of cellulose is essential for the production of valuable cellooligosaccharides and cellobiose from lignocellulosic biomass. However, enzymatic cellulose hydrolysis involves multiple synergistically acting enzymes, making difficult to control the depolymerization process and generate desired product. This work exploits the varying adsorption properties of the cellulase components to the cellulosic substrate and aims to control the enzyme activity. Cellulase adsorption was favored on pretreated cellulosic biomass as compared to synthetic cellulose. Preferential adsorption of exocellulases was observed over endocellulase, while β-glucosidases remained unadsorbed. Adsorbed enzyme fraction with bound exocellulases when used for hydrolysis generated cellobiose predominantly, while the unadsorbed enzymes in the liquid fraction produced cellooligosaccharides majorly, owing to its high endocellulases activity. Thus, the differential adsorption phenomenon of the cellulase components can be used for the controlling cellulose hydrolysis for the production of an array of sugars.

In modern times SSM did not exist until the 21st century when an increasing number of countries began permitting same-sex couples to marry legally. This study presents statistical and related evidence concerning SSM worldwide, with special attention to the United States, where SSM has evolved into a major political and legal issue. In addition to examining data on levels and trends, differentials between men and women are investigated. The study also considers common arguments for and against SSM and likely changes in laws and policies that may occur. Although same-sex marriage now exists in a small number of countries and US states, its consequences and implications are being felt far beyond the borders of those countries and areas. In coming years same-sex marriage will remain a controversial and salient part of the legal, political, and cultural landscape, locally, nationally, and internationally.

    The numerical simulation of the discharge inception is an active field of applied physics with many industrial applications. In this work we focus on the drift-reaction equation that describes the electron avalanche. This phenomenon is one of the basic building blocks of the streamer model. The main difficulty of the electron avalanche equation lies in the fact that the reaction term is positive when a high electric field is applied. It leads to exponentially growing solutions and this has a major impact on the behavior of numerical schemes. We analyze the stability of a reference finite volume scheme applied to this latter problem. The stability of the method may impose a strict mesh spacing, therefore a proper stabilized scheme, which is stable whatever spacing is used, has been developed. The convergence of the scheme is treated as well as some numerical experiments.

  8. Retrospective Revaluation: The Phenomenon and Its Theoretical Implications

    Retrospective revaluation refers to an increase (or decrease) in responding to conditioned stimulus (CS X) as a result of decreasing (or increasing) the associative strength of another CS (A) with respect to the unconditioned stimulus (i.e., A-US) that was previously trained in compound with the target CS (e.g., AX−US or just AX). We discuss the conditions under which retrospective revaluation phenomena are most apt to be observed and their implications for various models of learning that are able to account for retrospective revaluation (e.g., Dickinson and Burke, 1996; Miller and Matzel, 1988; Van Hamme and Wasserman, 1994). Although retroactive revaluation is relatively parameter specific, it is seen to be a reliable phenomenon observed across many tasks and species. As it is not anticipated by many conventional models of learning (e.g., Rescorla and Wagner, 1972), it serves as a critical benchmark for evaluating traditional and newer models. PMID:26342855

    Full Text Available Normal human somatic cells have strictly limited proliferative capacity and reach a state of senescence when it becomes exhausted. It is believed that senescence is a response to extensive and irreparable DNA injury, localized in telomeric and/or non-telomeric regions of the genome. Main cause of this damage is oxidative stress, increasing due to deteriorated function of mitochondria. Senescent cells accumulate in tissues during aging, which is causatively linked with the development of various pathologies in elderly individuals, including cancer. This paper, prepared exactly 50 years after Leonard Hayflick’s discovery of the relationship between cellular senescence and organismal aging is aimed at presenting the current knowledge about molecular determinants of senescence, with particular emphasis paid to the role of oxidative stress, effectors of senescence at the level of cell cycle, markers of this phenomenon, and the effect of senescent cells on the development of certain age-related diseases.

  10. Condensation in a capped capillary is a continuous critical phenomenon.

    2007-06-01

    We show that condensation in a capped capillary slit is a continuous interfacial critical phenomenon, related intimately to several other surface phase transitions. In three dimensions, the adsorption and desorption branches correspond to the unbinding of the meniscus from the cap and opening, respectively, and are equivalent to 2D-like complete-wetting transitions. For dispersion forces, the singularities on the two branches are distinct, owing to the different interplay of geometry and intermolecular forces. In two dimensions we establish precise connection, or covariance, with 2D critical-wetting and wedge-filling transitions: i.e., we establish that certain interfacial properties in very different geometries are identical. Our predictions of universal scaling and covariance in finite capillaries are supported by extensive Ising model simulation studies in two and three dimensions.

    Cell competition is a type of short-range cell-cell interaction first observed in Drosophila melanogaster. In two heterogeneous cell populations, cells that have a higher fitness level would have a competitive advantage and grow at the cost of neighbor cells that have comparatively lower fitness. This interaction is due to differences in expression levels of a specific protein in the two cell populations, and it is known as cell competition. In this review, we have studied recent findings of cell competition in different biological processes in Drosophila as well as mammalian systems. The purpose of this review is to collate important studies of competitive cell interactions, and to understand its roles and importance as a central phenomenon. This review provides evidence of the relevance of cell competition in various physiological and pathological conditions, such as size control in organ development, stem cell maintenance, tissue repair, organ regeneration, aging, formation of memory, and cancer.

    It is textbook knowledge that chromophore aggregation generally quenches light emission. In this feature article, we give an account on how we observed an opposite phenomenon termed aggregation-induced emission (AIE) and identified the restriction of intramolecular rotation as a main cause for the AIE effect. Based on the mechanistic understanding, we developed a series of new fluorescent and phosphorescent AIE systems with emission colours covering the entire visible spectral region and luminescence quantum yields up to unity. We explored high-tech applications of the AIE luminogens as, for example, fluorescence sensors (for explosive, ion, pH, temperature, viscosity, pressure, etc.), biological probes (for protein, DNA, RNA, sugar, phospholipid, etc.), immunoassay markers, PAGE visualization agents, polarized light emitters, monitors for layer-by-layer assembly, reporters for micelle formation, multistimuli-responsive nanomaterials, and active layers in the fabrication of organic light-emitting diodes.

    1999-01-01

    We investigated the current characteristic in a vacuum diode with a Gridded cathode. The grid is located on a top of a Ferro - Electric disk with a uniform cathode on its back side. We found experimental evidence that the current in such a system exceeds Child - Langmuir limit, in agreement with results reported in [1]. Explanations to this phenomenon were given in term of the non-linear characteristic of the ferro - electric ceramic or by plasma-assisted emission and gap closure. Recently [2] it has been shown theoretically that electrostatic coupling between the dielectric disk and the vacuum gap is directly responsible to the excess of current. We shall report experimental results that may support this possibility

    2014-01-01

    The superconductor-to-insulator transition (SIT) is a phenomenon occurring in highly disordered superconductors and may be useful in the development of superconducting switches. The SIT has been demonstrated to be induced by different external parameters: temperature, magnetic field, electric field, etc. However, the electric field induced SIT (ESIT), which has been experimentally demonstrated for some specific materials, holds particular promise for practical device development. Here, we demonstrate, from theoretical considerations, the occurrence of the ESIT. We also propose a general switching device architecture using the ESIT and study some of its universal behavior, such as the effects of sample size, disorder strength and temperature on the switching action. This work provides a general framework for the development of such a device. (paper)

    1991-01-01

    Consideration is given to various adaptive reactions to low-level radiation, their association with an absorbed dose, dose rate, radiation quality and time-interval between exposures, as well as with a cell cycle phase. Possible mechanisms of the adaptive response and the character and role of DNA damages, that can induce gene expression of the adaptive response, are discussed. The data on the influence of a preliminary long-term exposure to low-level radiation on the radiosensitivity of biological objects are analyzed with due regard for the adaptive cell response. It is concluded that the adaptive response of cells to ionizing radiation is a particular case of the phenomenon of cell adaptation of the effect of genotoxic factors of the environment

    The premise is more than art imitates life, or technology imitates nature it is a nascent step to see how we might be unwittingly inspired and influenced. An example that might immediately come to mind is a starling murmuration (a phenomenon called scale-free correlation) and Intels recent Coachella music festival drone performance. Superconductivity is a macroscopic manifestation of a quantum phenomenon - choreographed electrons (i.e. an electron murmuration) that enable astonishing devices. There is indeed an intimate connectedness between biology and electromagnetism. Our brains are complex neural circuits generating magnetic fields with a magnitude around 100 femtoTesla (roughly one billion times weaker than a typical magnet used to tack notes to a refrigerator door). Migratory birds navigate by orienteering with respect to the Earth's magnetic field. Electromagnetic field therapy is used in orthopedics to aid in bone repair. The electric eel generates a large electric field for self-defense. Sharks apparently detect extremely weak electric fields for finding prey. And so on. There are similarities between the way a field of wheat responds to a breeze and the natural restoring forces of a semiconductor crystal. And waves in a slowly moving river can lap backwards against a peninsular shoreline mimicking a diffraction effect. Getting back to the introductory sentence and mysterious links over cosmic distances, in August 2016, China launched the Quantum Experiments at Space Scale (QUESS) satellite. The technology is based on a non-linear crystal that produces pairs of entangled photons whose attributes apparently remain entwined regardless of how far apart they are separated. This paper will, no doubt superficially, attempt to enumerate and examine these types of connections and parallelisms.

    2015-08-01

    While assisted suicide (AS) is strictly restricted in many countries, it is not clearly regulated by law in Switzerland. This imbalance leads to an influx of people-'suicide tourists'-coming to Switzerland, mainly to the Canton of Zurich, for the sole purpose of committing suicide. Political debate regarding 'suicide tourism' is taking place in many countries. Swiss medicolegal experts are confronted with these cases almost daily, which prompted our scientific investigation of the phenomenon. The present study has three aims: (1) to determine selected details about AS in the study group (age, gender and country of residence of the suicide tourists, the organisation involved, the ingested substance leading to death and any diseases that were the main reason for AS); (2) to find out the countries from which suicide tourists come and to review existing laws in the top three in order to test the hypothesis that suicide tourism leads to the amendment of existing regulations in foreign countries; and (3) to compare our results with those of earlier studies in Zurich. We did a retrospective data analysis of the Zurich Institute of Legal Medicine database on AS of non-Swiss residents in the last 5 years (2008-2012), and internet research for current legislation and political debate in the three foreign countries most concerned. We analysed 611 cases from 31 countries all over the world. Non-terminal conditions such as neurological and rheumatic diseases are increasing among suicide tourists. The unique phenomenon of suicide tourism in Switzerland may indeed result in the amendment or supplementary guidelines to existing regulations in foreign countries.

  19. Phenomenon of quantum low temperature limit of chemical reaction rates

    Gol'danskij, V.I.

    1975-01-01

    The influence of quantum-mechanical effects on one of the fundamental laws of chemical kinetics - the Arrhenius law - is considered. Criteria characterising the limits of the low-temperature region where the extent of quantum-mechanical tunnelling transitions exceeds exponentially the transitions over the barrier are quoted. Studies of the low-temperature tunnelling of electrons and hydrogen atoms are briefly mentioned and the history of research on low-temperature radiation-induced solid-phase polymerisation, the development of which led to the discovery of the phenomenon of the low-temperature quantum-mechanical limit for the rates of chemical reactions in relation to the formaldehyde polymerisation reaction, is briefly considered. The results of experiments using low-inertia calorimeters, whereby it is possible to determine directly the average time (tau 0 ) required to add one new link to the polymer chain of formaldehyde during its polymerisation by radiation and during postpolymerisation and to establish that below 80K the increase of tau 0 slows down and that at T approximately equal to 10-4K the time tau 0 reaches a plateau (tau 0 approximately equals 0.01s), are described. Possible explanations of the observed low-temperature limit for the rate of a chemical reaction are critically examined and a semiquantitative explanation is given for this phenomenon, which may be particularly common in combined electronic-confirmational transitions in complex biological molecules and may play a definite role in chemical and biological evolution (cold prehistory of life)

    Relationships between viruses and autoimmune diseases such as systemic lupus erythematosus (SLE) are still elusive. Recent reports demonstrated the association of some viral infections with peculiar clinical events in the general population, such as cytomegalovirus (CMV) with arterial damage and Parvovirus B19 (PV-B19) with hematologic abnormalities. We planned to look for this kind of viral imprinting in SLE, hypothesizing that traces of specific features of some viral infections might be found in some subsets of seropositive SLE patients. In 60 SLE patients recruited at our nephrologic center, serology for CMV, PV-B19, Epstein-Barr virus viral capsid antigen (EBV-VCA), Epstein-Barr nuclear antigen (EBNA) and Epstein-Barr virus early antigen (EBV-EA) was performed. chi2 and ANOVA were employed to compare the frequency and titers of antiviral antibodies in SLE patients with groups of transplant, hemodialysis and blood donor subjects. chi2, Fisher's test, Bonferroni and Scheffe's test were employed to compare the different biochemical/clinical features between seropositive and seronegative SLE patients. Univariate and multivariate analysis (logistic regression models) were employed to evaluate the odds ratio (OR) of different risk factors for vascular events (including Raynaud's phenomenon, deep venous thrombosis) and hematologic abnormalities (including severe anemia, leukopenia and thrombocytopenia). Anti-CMV (82%), anti-PV-B19 (60%), anti-EBV-VCA (92%) and EBV-EA (45%) IgG antibodies were frequent in SLE, with higher prevalence in comparison with the blood donor group and higher titers in comparison with transplant and hemodialysis groups. CMV seropositivity was a highly significant risk factor for Raynaud's phenomenon (OR +alpha in univariate and multivariate analysis = 13.51 using a correction of 0.5 in case of a zero event), but not for venous vascular events (OR = 1.31). An increased though not significant risk factor was found for antiphospholipid antibodies

    Full Text Available The discussion on the spirit possession phenomenon is related in this study to the more general question of the role of religious institutions as part in the development process of a people living in a limited geographical area of a wider national society. It is assumed that religion, like culture in general, has its specific institutional forms as result of the historical development of a society, but at the same time religion is a force shaping that history. People's cultural resources influence their social and economic development and form a potential creative element in it'. Some of the questions to be asked are: "How are specific religious practices related to the dynamics of change in the societies in question? What is the social and religious context in which the spirit possession phenomenon occurs in them? What social and economic relations get their expression in them? To what extent is spirit possession in this case a means of exerting values and creatively overcoming a crisis or conflict which the changing social and economic relations impose on the people? The established spirit possession cults are here seen as the institutional forms of religious experience. At the same time it becomes evident that there is institutionalization in process as well as deinstitutionalization of spirit possession where it occurs outside established institutional forms. Institution is taken as a socially shared form of behaviour the significance of which is commonly recognized by those who share it. By the term spirit possession cult is meant a ritual form of spirit possession of a group which is loosely organized and without strict membership. The context of the study is four ethnic groups in Eastern Tanzania, near the coast of the Indian Ocean. The general theme of the project is The Role of Culture in the Restructuring of Tanzanian Rural Areas. The restructuring refers to a villagisation programme carried out in the whole country.

  3. The e-book phenomenon: a disruptive technology

    Full Text Available The emergence of the e-book as a major phenomenon in the publishing industry is of interest, world-wide. The English language market, with Amazon.com as the major player in the market may have dominated attention, but the e-book has implications for many other languages and book markets. The pre-e-book publishing world can be seen as a system in which authors delivered texts to publishers, who evaluated, edited, printed and distributed the published text to bookshops and thence to libraries and individual readers. This process has been going on since Gutenberg’s re-invention of movable type in about 1439 (following its original invention in China in the 9th century, and the use of metallic type in Korea in 1234, in other words, for about the past 550 years. The invention of movable type was an instance of a disruptive technology: eventually putting monastic scribes out of business altogether. Similarly, the e-book has the potential to disrupt the processes for the production, distribution and use of authorial texts, and is already in the process of doing so. First, the phenomenon of self-publishing has emerged as a serious contender to the more formal process; secondly, publishers may derive significant economic benefit from the reduction in printing and distribution costs, as well as the ability to sell directly to the consumer through their own Websites; thirdly, the impact on booksellers may result in a further reduction in the number of independent stores – a decline already in process as a result of online bookselling; fourthly, user demand is resulting in libraries wrestling with the problems of how to manage e-books within their collection development and management processes; and, finally, the behaviour of readers is changing as the devices available for using e-books become more numerous and cheaper. Only someone blessed with absolute certainty in forecasting the future can know exactly how things will change, but there is little

    2014-05-01

    The use of fluorescence to quantify and characterise aquatic organic matter in river, ocean, ground water and drinking and waste waters has come along way since its discovery as a phenomenon in the early 20th century. For example, there are over 100 papers published each year in international peer reviewed journals, an order of magnitude increase since a decade ago (see Figure taken from ISI database from 1989 to 2007 for publications in the fields of river water and waste water). Since then it has been extensively used as a research tool since the 1990's by scientists and is currently used for a wide variety of applications within a number of sectors. Universities, organisations and companies that research into aquatic organic matter have either recently readily use appropriate fluorescence based techniques and instrumentation. In industry and government, the technology is being taken up by environmental regulators and water and wastewater companies. This keynote presentation will give an overview of aquatic organic matter fluorescence from its conception as a phenomenon through to its current use in a variety of emerging applications within the sectors concerned with understanding, managing and monitoring the aquatic environment. About the Speaker Darren Reynolds pioneered the use of fluorescence spectroscopy for the analysis of wastewaters in the 1990's. He currently leads a research group within the Centre for Research in Biosciences and sits on the Scientific Advisory Board for the Institute of Bio-Sensing Technology at the University of the West of England, Bristol. He is a multidisciplinary scientist concerned with the development of technology platforms for applications in the fields of environment/agri-food and health.

  5. Twinning in Zircon: Not a High-Pressure Phenomenon

    2017-12-01

    Microtwins in zircon are commonly found in shocked terrestrial and extraterrestrial samples and are potentially important for shock history and crater reconstruction. Twinning is easily observed with both the optical microscope and variety of electron beam techniques. Twinning as a deformation mechanism is consistent with the high strain rates generated during impact. No constitutive relationships, or even general limits on the physical conditions required for twinning in zircon are known, however. Present speculation on the critical quantity for twin formation, i.e. 10s of GPa of shock pressure (Moser et al. 2011, Timms et al., 2012), has no basis in the underlying mechanisms of twin nucleation, which are related to the motion of dislocations. This erroneous value is due to conflation of twinning sensu stricto with a phase transformation to reidite. Reidite occurs as twin-like lamellae occupying the {112} planes which are thought to be a mirror plane for twinning. We review the crystallographic theory of twinning in zircon. We then evaulate several theories on the nucleation of twins along with their necessary stresses involved. Our aim is to show that shock microtwins in zircon can be a `low pressure' shock phenomenon. This 'low pressure' hypothesis is supported by natural samples. These zircons are from the lower crust nearly 80 km from the centre of the Vredefort impact structure—the most distal zircon shock microstructures yet found in the lithosphere. Twins are present in 10% of the zircon grains greater than 50 µm in diameter. As an extensive, 'low pressure' phenomenon, twins are an easily recognized and potentially widespread record of Earth's impact history.Moser, D.E., Cupelli, C. L., Barker, I., Flowers, R.

    The aim of this study was to explore smoking among adolescents and to examine the attitudes of parents to this patology. MATEIAL AND METHODS: the study included 180 adolescents of promary school and 40 parents.Research was conducted by questionnaire containing questions on smoking among youths., the avalibaility of and reasons for reaching for a cigarette. Parents also answered questions concerning knowledge about this pathology and how to deal with it. The study shows that 20% of sixth grade students of primary school has had a first initiation nicotine. The surveyed parents/carers feel that the biggest threat in the school environment is not smoking (12.5%), but drug abuse (80%). 31% of respondents believe that these phenomena are inherent. Parents/guardians are aware of the risks which are inherent to smoking, but do not know how to figh him. Pupils from Year 6 of primary school are exposed in school to smoke. There is a need for education of young people and parents of the dangers of smoking and prevention of this pathology. Parents do not know how to prevent smoking among adolescents and to turn to for help. Common activities at school, parents and local communities seem to be an alternative to this phenomenon.

    In this study of the phenomenon of the postpartum period grounded theory methodology was used to investigate the experiences of first-time mothers during the first three months following their deliveries. The sample consisted of 12 primipara women and 3 multipara women. The data were generated by using unstructured interviews and field notes. Each woman was interviewed twice, the first time between 2 and 3 weeks postpartum, and the second time between 10 and 12 weeks postpartum. The final data for analysis consisted of: data generated through interviews, field notes, and the narratives of four mothers found in the non-fiction literature. Constant comparative analysis resulted in the generation of four categories and corresponding subcategories. These were: (1) Giving of Self; (2) Redefining Self; (3) Redefining Relationships; and (4) Redefining Professional Goals. The categories were not mutually exclusive. All the categories converged to provide support for the core variable 'Dialectic in Becoming a Mother'. The dialectic perspective demonstrated that, in becoming mothers, the women experienced transition, contradictions, tensions and transformations. A theoretical model was developed to show relationships among these major concepts. The findings of this study will be useful in effecting change in the provision of care to postpartum women and their families.

    This study examined bullying and cyberbullying prevalence among 367 adolescents 10 to 18 years of age who were attending schools and community organizations in suburban and urban neighborhoods in the Midwest United States. The correlational design investigated adolescents' daily use of technology that could be used to cyberbully peers, such as cell phones, computers, email, and the Internet. Results showed that 30% of participants had been bullied during school, and 17% had been cyberbullied, with online social networking sites the most common media employed (68%). The majority of participants owned or had access to computers (92%), email accounts (88%), social networking accounts (e.g., Facebook or MySpace) (82%), and cell phones (79%). Daily technology use included an average of two hours on a computer and a median of 71 text messages per day. Logistic regression analysis revealed no significant differences in bullying or cyberbullying prevalence based on location (urban or suburban) or demographic characteristics. Given the substantial presence of cyberbullying and the increase in technology use among adolescents in the 21st century, nurses need knowledge of the phenomenon to plan assessments in clinical practice. Early identification and assessment of cyberbullying victims and perpetrators, and development and implementation of effective interventions are needed to reduce this form of bullying among adolescents.

    The current understanding of Alzheimer's disease (AD) is based on the Aβ and tau pathology and the resulting neuropathological changes, which are associated with manifested clinical symptoms. However, electrophysiological brain changes may provide a more expansive understanding of AD. Hence, the objective of this systematic review is to propose a theory about the electrophysiological phenomenon of Alzheimer's disease (EPAD). The review of literature resulted from an extensive search of PubMed and MEDLINE databases. One-hundred articles were purposively selected. They provided an understanding of the concepts establishing the theory of EPAD (neuropathological changes, neurochemical changes, metabolic changes, and electrophysiological brain changes). Changes in the electrophysiology of the brain are foundational to the association or interaction of the concepts. Building on Berger's Psychophysical Model, it is evident that electrophysiological brain changes occur and affect cortical areas to generate or manifest symptoms from onset and across the stages of AD, which may be prior to pathological changes. Therefore, the interaction of the concepts demonstrates how the psychopathology results from affected electrophysiology of the brain. The theory of the EPAD provides a theoretical foundation for appropriate measurements of AD without dependence on neuropathological changes. Future research is warranted to further test this theory. Ultimately, this theory contributes to existing knowledge because it shows how electrophysiological changes are useful in understanding the risk and progression of AD across the stages.

    A typical time management phenomenon is the rush before a deadline. Behavioral decision making research can be used to predict how behavior changes before a deadline. People are likely not to work on a project with a deadline in the far future because they generally discount future outcomes. Only when the deadline is close are people likely to work. On the basis of recent intertemporal choice experiments, the authors argue that a hyperbolic function should provide a more accurate description of the deadline rush than an exponential function predicted by an economic model of discounted utility. To show this, the fit of the hyperbolic and the exponential function were compared with data sets that describe when students study for exams. As predicted, the hyperbolic function fit the data significantly better than the exponential function. The implication for time management decisions is that they are most likely to be inconsistent over time (i.e., people make a plan how to use their time but do not follow it).

    The ability to predict in situ stress conditions from standard core samples offers planning and site-selection advantages for most underground facilities. This paper presents an empirical relation for estimating the horizontal to vertical stress ratio in basalt. The resulting estimates can then be used to help assess the extent to which measurement of in situ stress is required. The core disking phenomenon has long been used as an indicator of high in situ stress. It is concluded that disks form as the result of tensile failure initiation rather than shear failure initiation of the core. It is deduced that the tensile failure begins at the edge of the core and propagates toward the center in shear rather than beginning at the center and propagating outward. An empirical relation for horizontal to vertical stress ratio variation with depth has been developed and is shown to agree substantially with previous measured horizontal to vertical stress ratios for locations in several areas of the world. The stress-ratio predictions are justified based on finite-element studies using linear elastic analysis and also nonlinear (tension cut-off) analysis. Indications of fracture propagation paths were determined from the analyses. The shape of the predicted propagation path agrees well with physical observations

    Branch occlusion of the anterior cerebral artery (ACA) is regarded as a part of Moyamoya disease. The purpose of this study is to define the ACA steal phenomenon (SP) in Moyamoya disease and to evaluate temporal changes according to the disease progression. From 139 Moyamoya patients we defined ACASP as narrowing of the ipsilateral A1-2 junction while preserving the anterior communicating artery and supplying the contralateral ACA cortical branches with the development of leptomeningeal collaterals by the ipsilateral middle cerebral artery into the hypoperfused ipsilateral ACA territory. Direction of the steal related to the stage in both hemispheres by Suzuki classification was statistically analyzed using the binomial test based on binomial distribution. Follow-ups of ACASP were evaluated in five patients. We identified ACASP in 13 (9%) patients (male:female=7:6, mean age 18 years, range: 2-58 years) of the 139 study patients. The presenting pattern was ischemic in 12 and hemorrhagic in one. The direction of SP occurred from the hemisphere in the lower to the higher stage of Suzuki classification (two-tail P value=0.0002). After revascularization surgery, ACASP disappeared or diminished. ACASP may occur in bilaterally different stages of Moyamoya disease as a transient self-adaptive process. It regresses after revascularization surgery. (orig.)

  14. Reconsolidation revisited: a review and commentary on the phenomenon.

    Consolidation and reconsolidation constitute a large proportion of current research into memory formation. The evidence in favour of the Consolidation Theory is widespread, on both the cellular and systems level. Research has indicated that consolidation and reconsolidation employ similar mechanisms; both consolidation and reconsolidation of memory require protein synthesis and glutaminergic input, and both seem to be associated with the hippocampal formation. Despite this, other data seem to argue that the two concepts are entirely separate processes. The great interest in this topic is shown in the proliferation of studies. The current literature has been subject to extensive and continual review. The current manuscript attempts to address the inconsistency in the consolidation-reconsolidation literature by providing a selective review of some of the most pertinent experimental work in both areas. The core question underpinning this review paper is whether reconsolidation is an entity distinct from consolidation, or merely an extension of the consolidation process. It is concluded that consolidation and reconsolidation may be distinct, albeit similar, processes, and that only a subset of the brain areas involved in consolidation are implicated in reconsolidation. In addition, with advances in our understanding of, and approach to these processes (i.e., incorporation of boundary conditions of reconsolidation into the design of contemporary studies and the increased awareness of the need to temper the interpretation of data emerging from studies employing divergent methodologies), it is suggested that future reconsolidation research may yield significant progress into the vast potential underpinning the reconsolidation phenomenon.

    Under some author's opinion the wind is not a periodical phenomenon and therefore it is more reasonable to invest in renewable periodical energies as tides. In this paper we have developed a computer application based in MatLab {sup copyright}, that through the FFT (Fast Fourier Transform) analyzes the variations of wind speed amplitude in the time and frequency domain. The data were sampled every 10 min in the period 2000-2008. The data come from 31 Automatic Meteorological Stations (EMAs), the country of Mexico and correspond one per state. The survey shows the representation of spectral-temporal surfaces to long time intervals, as one year or more and denotes seasonal envelopes that alter the pattern at certain times everyday. As a conclusion, the wind has an important periodical component for the country of Mexico, since the fundamental component of the wind speed represents a frequency of 1/24 h{sup -1} in a very accurate form throughout the time studied. To harness the wind potential of the country of Mexico it should be kept in mind that there is a minimum wind speed between 8 and 16 h and a maximum close to 24 h. (author)

  16. Raynaud's Phenomenon: a Brief Review of the Underlying Mechanisms

    2016-11-01

    Full Text Available Raynaud's phenomenon (RP is characterized by exaggerated cold-induced vasoconstriction. This augmented vasoconstriction occurs by virtue of a reflex response to cooling via the sympathetic nervous system as well as by local activation of α2C adrenoceptors (α2C-AR. In a cold-initiated, mitochondrion-mediated mechanism involving reactive oxygen species and the Rho/ROCK pathway, cytoskeletal rearrangement in vascular smooth muscle cells (VSMCs orchestrates the translocation of α2C-AR to the cell membrane, where this receptor readily interacts with its ligand. Different parameters are involved in this spatial and functional rescue of α2C-AR. Of notable relevance is the female hormone, 17β-estradiol, or estrogen. This is consistent with the high prevalence of RP in pre-menopausal women compared to age-matched males. In addition to dissecting the role of these various players, the contribution of pollution as well as genetic background to the onset and prevalence of RP are also discussed. Different therapeutic approaches employed as treatment modalities for this disease are also highlighted and analyzed. The lack of an appropriate animal model for RP mandates that more efforts be undertaken in order to better understand and eventually treat this disease. Although several lines of treatment are utilized, it is important to note that precaution is often effective in reducing severity or frequency of RP attacks.

    Pre-glow is the multi-charged ion current burst that may occur at the beginning of the beam pulse. Pre-glow effect investigation is one of topical directions of ECR ion sources development at present. Pre-glow is of interest for efficient short-pulsed multicharged ion source creation. Particularly, such source of intense beams of short living radioactive isotopes multi-charged ions is one of key elements in 'Beta-Beam' European project. The use of Pre-glow-generating regime of an ECRIS operation is a promising way of pulsed high-intense multi-charged ion beams production with much shorter edges in comparison with usual operation regime. Numerical simulations made with the updated theoretical model allow authors to propose more physical and intuitive explanations of Pre-glow phenomenon origins. The obtained dependences of Pre-glow characteristics on experimental conditions offer a scaling for a wide range of ECRIS. The propose scaling demonstrates that an ECR source with plasma heating by radiation at frequency of 37 GHz and higher seems to be the most effective in terms of currents, pre-glow intensity and mean ion charge.

    When Jeremiah Horrocks first observed it in 1639, the transit of Venus was a desirable telescopic target because of its scientific value. By the next transit of Venus in 1761, though, the enlightened public also embraced it as a popular celestial phenomenon. Its stature elevated over the centuries, the transit of Venus has been featured in music, poetry, stamps, plays, books, and art. The June 2004 transit emerged as a surprising global sensation, as suggested by the search queries it generated. Google's Zeitgeist deemed Venus Transit to be the #1 Most Popular Event in the world for that month. New priorities, technologies, and media have brought new audiences to the rare alignment. As the 2012 transit of Venus approaches, the trend continues with publicly accessible capabilities that did not exist only eight years prior. For example, sites from which historic observations have been made are plotted and readily available on Google Earth. A transit of Venus phone app in development will, if fully funded, facilitate a global effort to recreate historic expeditions by allowing smartphone users to submit their observed transit timings to a database for quantifying the Astronomical Unit. While maintaining relevance in modern scientific applications, the transit of Venus has emerged as a cultural attraction that briefly intrigues the mainstream public and inspires their active participation in the spectacle.

    Full Text Available This paper attempts to give a general outline of the phenomenon of well­known American writer and philosopher Ayn Rand in contemporary social and ethical space. Application to the research of life, literary and philosophical heritage of the writer makes it possible to assess its impact on the current situation in politics and philosophy. Review of Ayn Rand’s artistic positions confirms her role as a landmark figure, who represented at that time the actual socio­cultural request of active man in contemporary philosophy and politics, “putting down” in literary form complex of philosophical questions to the level of the ordinary man. Ayn Rand is the focus of the social practices in which she was formed, lived and worked. The ideas of almost all philosophical subjects are presented in her works in a simple way, but they are fundamentally different from conventional notions of ethics, politics and philosophy in general, even the ideas of philosophers, whom she honored, such as Aristotle. That’s why modern philosophers are interested in studying her works now. After all, still there has no comprehensive academic analysis of her philosophical and scientific works of art.

    Cascade phenomenon may lead to catastrophic disasters which extremely imperil the network safety or security in various complex systems such as communication networks, power grids, social networks and so on. In some flow-based networks, the load of failed nodes can be redistributed locally to their neighboring nodes to maximally preserve the traffic oscillations or large-scale cascading failures. However, in such local flow redistribution model, a small set of key nodes attacked subsequently can result in network collapse. Then it is a critical problem to effectively find the set of key nodes in the network. To our best knowledge, this work is the first to study this problem comprehensively. We first introduce the extra capacity for every node to put up with flow fluctuations from neighbors, and two extra capacity distributions including degree based distribution and average distribution are employed. Four heuristic key nodes discovering methods including High-Degree-First (HDF), Low-Degree-First (LDF), Random and Greedy Algorithms (GA) are presented. Extensive simulations are realized in both scale-free networks and random networks. The results show that the greedy algorithm can efficiently find the set of key nodes in both scale-free and random networks. Our work studies network robustness against cascading failures from a very novel perspective, and methods and results are very useful for network robustness evaluations and protections.

  3. A Plant's Response to Gravity as a Wave Guide Phenomenon

    1997-11-01

    Plant experimental data provides a unifying wave theory (W-wave theory) for the growth and development of plants. A plant's response to gravity is an important aspect of this theory. It appears that a plant part is tuned to the angle with which it initially grew with respect to the gravitational field and changes produce correction responses. This is true because the velocity of W-waves (whose standing waves determine plant structure) within plant tissue is found to be different in different directions (angle a) with respect to the gravitational field. I found that there are preferred values of a, namely integral multiples of near 5 degrees for some plants. Conifers apparently are more sensitive to the gravitational field than deciduous trees, in the cases studied, so their structure is determined in more detail by the gravitational field. A plant's response to gravity appears to be a fundamental phenomenon and may provide a new model for gravity that can be experimentally verified in the laboratory. Along these same lines accelerometers placed in plant tissue indicate that plants produce gravity related forces that facilitate sap flow. See the

    Eating disorders are common but underdiagnosed illnesses. Help-seeking for co-occurring issues, such as anxiety and depression, are common. To identify the prevalence of eating problems, using the SCOFF, and eating disorders when screening positive on the SCOFF (i.e., ≥2), among patients seeking help for anxiety and depression at a community-based mental health service. Patients (N = 260) consecutively referred and assessed for anxiety and depression treatment were administered the SCOFF screening questionnaire and a semi-structured standardized diagnostic interview during routine intake. 18.5% (48/260) scored ≥2 on the SCOFF, indicating eating problems. Of these, 41% (19/48) met criteria for an eating disorder. Thus, overall, 7.3% (19/260) of the sample met criteria for a DSM-IV eating disorder. Those scoring ≥2 on the SCOFF were more likely to: be female (p = 0.001), younger (p = 0.003), and have a history of self-harm (p eating disorders are a hidden phenomenon in general outpatient mental health. By using a standardized diagnostic interview to establish diagnosis rather than self- or staff-report, the study builds on limited previous findings. The naturalistic study setting shows that screening for eating disorders can be easily built into routine intake practice, and successfully identifies treatment need.

    Transverse magnetoresistance in amorphous magnetic alloys (Fe/sub 1-//sub x/CO/sub x/) 82 Cu/sub 0.4/Si/sub 4.4/B/sub 13.2/ were measured at room temperature and in the magnetic field range 0--15 kOe. For large magnetic field, three different functional dependences of magnetoresistance on magnetic field strength have been found as follows: (1) Δrho/rho approaches saturation. (2) Δrho/rho increases proportionally to H 2 . (3) For x = 0.15, a sharp Δrho/rho peak appears at a certain magnetic field strength in spatial angular orientation of both magnetic field and electric currents. Case (3) is a magnetic breakdown phenomenon. Magnetic breakdown occurs at the gap between the spin-up and spin-down sheets of the Fermi surface. This gap is the spin-orbit gap and its magnitude is a sensitive function of magnetization. Hence the magnitude and width of the magnetoresistance peak and the magnetic field strength at the peak point are functions of angular orientation of both magnetic field and electric current

  6. CONSIDERATIONS ON THE DROUGHT PHENOMENON IN CLUJ COUNTY

    Full Text Available Considerations on the drought phenomenon in Cluj County. Cluj county area is 6674 km², and is located in the northwestern part of Romania. The climate is temperate continental with oceanic influences, relatively humid, but there are also periods of drought and even years with deficient rainfall, as there are periods of excess rainfall. Dryness and drought phenomena are caused by cosmic, climatic, hydrological (groundwater depth, the existence of surface water sources factors, features of the underlying surface, vegetation coverage, soil texture and structure. The relief determines a climate elevation with differences in terms of precipitation and temperatures quantities. To calculate the dryness degree of the climate at weather stations in the Cluj county, the Emmanuel de Martonne aridity index was used. Drought do not induce into the substrate the geomorphologic processes per se, however, they pave the way for starting the deflation process, surface erosion and ravine, by reducing the cohesion between the particles and the formation of deep cracks in the soil and even rock. In these climatic conditions, droughts are less frequent in the county of Cluj, in relation to the extra-Carpathian regions and are distributed unevenly across the county. The number of periods of drought decreases with the increase of the altitude, from an average of 2.6 drought periods a year at Dej (altitude of 232 m to an annual average of 0.3 draught periods at Vlădeasa Peak (altitude of 1836 m.

    Parents are under pressure from their adolescent children if they, contrary to their own convictions, are compelled to bend rules or adapt decisions to submit to the demands of their children. The objective of this investigation was to determine which factors contribute to this phenomenon. The sample comprised 177 adolescents and their parents in the Mpumalanga province. Variables taken into account were individual factors (gender, age and personality of parents and adolescents); factors related to the family (family structure, working circumstances of parents, family relationships and birth order position of adolescents); developmental factors (identity formation of adolescents); and wider contextual factors (peer pressure during adolescence). From the parents' side factors such as self-concept, personality and parent-adolescent relationship explained almost 62% of the variance in the pressure that parents experience. Only one prominent adolescent factor could be identified, namely adolescent-parent relationship (seen from the adolescents' side). The results indicate that the pressure which parents encounter from their adolescent children is associated with parental variables rather than adolescent variables. Adolescents do not deliberately plan to place their parents under pressure, but factors on the parents' side create such a situation.

  8. CD3-positive B cells: a storage-dependent phenomenon.

    Directory of Open Access Journals (Sweden)

    Angela Nagel

    Full Text Available The majority of clinical studies requires extensive management of human specimen including e.g. overnight shipping of blood samples in order to convey the samples in a central laboratory or to simultaneously analyze large numbers of patients. Storage of blood samples for periods of time before in vitro/ex vivo testing is known to influence the antigen expression on the surface of lymphocytes. In this context, the present results show for the first time that the T cell antigen CD3 can be substantially detected on the surface of human B cells after ex vivo storage and that the degree of this phenomenon critically depends on temperature and duration after blood withdrawal. The appearance of CD3 on the B cell surface seems to be a result of contact-dependent antigen exchange between T and B lymphocytes and is not attributed to endogenous production by B cells. Since cellular subsets are often classified by phenotypic analyses, our results indicate that ex vivo cellular classification in peripheral blood might result in misleading interpretations. Therefore, in order to obtain results reflecting the in vivo situation, it is suggested to minimize times of ex vivo blood storage after isolation of PBMC. Moreover, to enable reproducibility of results between different research groups and multicenter studies, we would emphasize the necessity to specify and standardize the storage conditions, which might be the basis of particular findings.

    Full Text Available The aim of this work is structuring categorical-conceptual apparatus of the of the tax losses phenomenon in the state budgetary resources, namely clarification of the concepts of “tax gap”, “tax expenditures”, “tax losses”, as well as the quantification of tax losses of the Consolidated budget of Ukraine. Methodology. Most modern scholars interpret the tax gaps as the amount of taxes that were not received with the budget as a result of shadow economy, tax evasion and the existence of tax debt. However, considerable asymmetry of the tax component of the state budgetary resources also arises due to budget losses of all levels as a result of providing tax exemptions. In modern economic literature such losses are considered as tax expenditures. We consider tax losses a generalizing concept including potential amounts of tax revenues that the state and local budgets have not received as a result of the existence of the phenomenon of “tax gaps” and “tax expenditures”, and the amount of losses of the state budgetary resources in terms of their tax component is equal to the sum total of tax exemptions provided, unsettled tax debt of economic agents and the loss of tax revenue due to the operation of shadow economy. The study is based on the analysis of tax losses of budgetary resources of Ukraine during the period of time from 2004 to 2014. The results of the study showed enormous losses of budgetary resources in Ukraine due to the imperfection of the tax system, spread of undisclosed operations, tax evasion, and inefficient fiscal policy implementation. The Consolidated budget loses the amounts of monetary funds, equal to an average of 53.30% of actual revenue over the period studied. Total tax losses of the state budgetary resources in 2014 are equivalent to the total actual expenditures of the Consolidated budget of Ukraine on social protection and social security, defense, public order, security and judicial authorities.

    The objective of this study was to evaluate the long-term follow-up of patients with Raynaud's phenomenon (RP) and pathological nailfold capillaroscopy (NC) in order to analyse the predictive value of specific features of capillaroscopy for the development of a connective tissue disease (CTD). From 1992 to 2002, NC alone or combined with fluorescence videomicroscopy with sodium fluorescein (NaF) was performed in 1024 consecutive patients because of RP. We analysed the follow-up and pathological features of NC in all patients who had neither clinical nor serological signs of a CTD at the time of NC. Of 308 patients with neither serological findings nor clinical signs of CTD but with RP and pathological features in NC suspicious for CTD, follow-up data were available for 133 patients. An additional NaF test had been performed in 51 (38.4%) patients. After a mean follow-up of 6.5 years (range: 1-15 years), 109 patients had developed a CTD and 24 patients did not show any clinical signs or serological markers for a CTD after a mean follow-up of 8.5 years (range: 2-15 years). There were no differences in age, duration of RP or of follow-up in patients who developed a CTD compared to patients who did not. Significantly more giant capillaries (p=0.0001), avascular fields (p=0.02) and irregular architecture (p=0.0001) had been observed in patients who had developed a CTD during the follow-up of 6.5 years. The presence of giant capillaries, avascular fields and irregular architecture of nailfold capillaries is predictive for the development of a CTD in patients with RP.

    Full Text Available Leonard F Vernon Sherman College of Chiropractic, Spartanburg, SC, USA Abstract: The standard definition of spontaneous regression (SR of cancer is as follows, “…when a malignant tumor partially or completely disappears without treatment or in the presence of therapy which is considered inadequate to exert a significant influence on neoplastic disease.” SR is also known as Saint Peregrine tumor, the name taken from a young priest, Peregrine Laziosi (1260 [5]–1345, exact date is unknown, who had been diagnosed with a tumor of the tibia. The mass eventually grew so large that it broke through the skin and became severely infected. The available treatment for this condition was limited to amputation. Historical records report that on the day of surgery, physicians found that the tumor had disappeared and reportedly never returned. To date, the medical literature consists only of individual case studies and overviews of this phenomenon. The most cited work on the subject was done by surgeons Tilden Everson and Warren Cole who reviewed 176 published cases of SR from 1900 to 1960. While a percentage of these were found not to be cases of SR, there remained a number of unexplained cases. A frequent theme in many cases of SR is the co-occurrence of infection. Given the current interest in immunotherapy in the treatment of cancer, this article discusses one of the very early pioneers of this theory, William Bradley Coley, MD, a surgeon who was clearly ahead of his time. Ostracized by colleagues for his belief that stimulation of the immune system could in fact produce a regression of cancer, Coley remained convinced that his theory was right and, while he was not familiar with cytokines such as tumor necrosis factor (TNF, interferons, and streptokinase, he knew instinctively that an innate immune response was taking place.

    Full Text Available Abstract Background The flexion relaxation phenomenon (FRP represents a well-studied neuromuscular response that occurs in the lumbar and cervical spine. However, the cervical spine FRP has not been investigated extensively, and the speed of movement and loading effects remains to be characterized. The objectives of the present study were to evaluate the influence of load and speed on cervical FRP electromyographic (EMG and kinematic parameters and to assess the measurement of cervical FRP kinematic and EMG parameter repeatability. Methods Eighteen healthy adults (6 women and 12 men, aged 20 to 39 years, participated in this study. They undertook 2 sessions in which they had to perform a standardized cervical flexion/extension movement in 3 phases: complete cervical flexion; the static period in complete cervical flexion; and extension with return to the initial position. Two different rhythm conditions and 3 different loading conditions were applied to assess load and speed effects. Kinematic and EMG data were collected, and dependent variables included angles corresponding to the onset and cessation of myoelectric silence as well as the root mean square (RMS values of EMG signals. Repeatability was examined in the first session and between the 2 sessions. Results Statistical analyses revealed a significant load effect (P Conclusions The load increase evoked augmented FRP onset and cessation angles as well as heightened muscle activation. Such increments may reflect the need to enhance spinal stability under loading conditions. The kinematic and EMG parameters showed promising repeatability. Further studies are needed to assess kinematic and EMG differences between healthy subjects and patients with neck pain.

    OBJECTIVE: Kasabach-Merritt phenomenon (KMP) can lead to life-threatening bleeding, and its optimum treatment has not been established. We review the experience of managing KMP in a single institution. METHODS: A retrospective chart review on all children with KMP treated at the Hospital for Sick Children, Toronto, over an 18 yr period was carried out. RESULTS: All 15 patients had profound thrombocytopenia and hypofibrinogenemia at presentation, half had bleeding symptoms, and three had cardiac failure. All patients received corticosteroids. Five responded to steroids alone, given for an average of 13 wk, increasing platelets to >20 x 10(9)\\/L at a mean of 6.2 d and fibrinogen >1 g\\/dL at 25.6 d. Ten patients received at least one other therapeutic modality in addition to steroids, including vincristine, interferon, anti-platelet agents and pentoxifylline. Five patients received vincristine, for a mean of 6 wk, with two patients responding. Eight patients received interferon, for a mean of 4 months, with two patients responding. Overall, the mean time to increasing platelets >20 x 10(9)\\/L was 56 d, to >150 x 10(9)\\/L was 88 d and fibrinogen >1 g\\/dL 49 d. Ten patients showed a partial response to embolisation, with a mean of 2.8 procedures performed. Thrombotic complications occurred in 7%. Twelve patients remain alive, with relapse in six patients, all treated successfully. One patient died, and two patients have been lost to follow-up. CONCLUSION: KMP is a rare condition, with significant morbidity and mortality. The therapeutic approach should include a multidisciplinary team and consensus on guidelines.

  15. Economy As A Phenomenon Of Culture: Theoretical And Methodological Analysis

    Directory of Open Access Journals (Sweden)

    S. N. Ivaskovsky

    2017-01-01

    Full Text Available The article redefines economy as a phenomenon of culture, a product of a historically and socially grounded set of values shared by members of a given society. The research shows that culture is not always identical to social utility, because there are multiple examples when archaic, traditionalist, irrational cultural norms hinder social and economic progress and trap nations into poverty and underdevelopment. One of the reasons for the lack of scholarly attention to cultural dimension of economy is the triumph of positivism in economics. Mathematics has become the dominant language of economic analysis. It leads to the transformation of the economics into a sort of «social physics», accompanied by the loss of its original humanitarian nature shared in the works of all the great economists of the past. The author emphasizes the importance of the interdisciplinary approach to the economic research and the incorporation of the achievements of the other social disciplines – history, philosophy, sociology and cultural studies - into the subject matter of economic theory. Substantiating the main thesis of the article, the author shows that there is a profound ontological bond between economy and culture, which primarily consists in the fact that these spheres of human relations are aimed at the solution of the same problem – the competitive selection of the best ways for survival of people, of satisfying the relevant living needs. In order to overcome the difficulties related to the inclusion of culture in the set of analytical tools used in the economic theory, the author suggests using a category of «cultural capital», which reestablishes the earlier and more familiar for the economists meaning of capital.

    2003-03-01

    This review attempts to summarize and discuss contemporary pathogenetic views on vibration-induced Raynaud's phenomenon assuming its multifactorial etiology. An increase in central and peripheral sympathetic nervous activity is discussed based on different physiological indicators of autonomic dysfunction and sympathetic hyperactivity. Local acral vasodysregulation is considered. Receptor and nerve endings dysfunction presented with predominance of alpha(2)-receptor function in the digital arteries and neuronal loss in those digital cutaneous perivascular nerves containing calcitonin gene-related peptide result in deficiency of endogenous release of this powerful vasodilator. Endothelial damage and dysregulation induced by vibration and increased shear stresses are demonstrated by the elevated plasma level of thrombomodulin and of von Willebrand factor and reduced endothelium-dependent vasodilator responses. The concentrations of endothelin-1 are high, the highest being in most advanced stages. Decreased plasma thiol level, indicating increased production and activity of free radicals, contribute to vasospastic paroxysms in vibration white finger patients. Dysbalance of local vasoactive factors with opposing effects on vascular smooth muscle like endothelin and nitric oxide, endothelin and calcitonin gene-related peptide, nitric oxide and superoxide anion are discussed. Disturbed smooth muscle response is supposed. Changes in hemostasis, fibrinolysis and hemorrheology, activation of blood cells with erythrocyte hyperaggregation and red cell hypodeformability, platelet aggregation with increased release of vasoconstricting thromboxane A(2) and serotonin as well as leukocyte activation, entrapment within capillaries and post-capillary venules and increased reactive oxygen species and lysosomal lytic enzymes release might also contribute to digital vasospasms and tissue damage. Elevated soluble intercellular adhesion molecule-1 levels involved in the adherence of

Many factors in the interesting interaction between genotype and phenotype (eg, high cardiorespiratory fitness, higher hemoglobin concentration, good metabolic efficiency, muscle fiber composition, enzyme profile, diet, altitude training, and psychological aspects have been proposed in the attempt to explain the extraordinary success of these runners. Increasing evidence shows that genetics may be a determining factor in physical and athletic performance. But, could this also be true for African long-distance runners? Based on this question, this brief review proposed the role of genetic factors (mitochondrial deoxyribonucleic acid, the Y chromosome, and the angiotensin-converting enzyme and the alpha-actinin-3 genes in the amazing athletic performance observed in African runners, especially the Kenyans and Ethiopians, despite their environmental constraints.Keywords: genes, genotype, physical exercise, endurance runners

    2015-04-01

    Urban Heat Island (UHI) phenomenon is well known in scientific literature since first half of the 19th century [1]. By now a wide number of world capitals is described from climatological point of view, especially in mid-latitudes. In beginning of XXI century new studies focus on heat island of tropical cities. However dynamics UHI in extreme continental climates is insufficiently investigated, due to the fact that there isn't large cities in Europe and Northern America within that climate type. In this paper we investigate seasonal and diurnal dynamics UHI intensity for Astana, capital city of Kazakhstan (population larger than 835 000 within the city) including UHI intensity changes on different time scales. Now (since 1998) Astana is the second coldest capital city in the world after Ulaanbaatar, Mongolia [3] For this study we use the UHI investigation technology, described in [2]. According to this paper, we selected three stations: one located into city in high and midrise buildings area (including extensive lowrise and high-energy industrial - LCZ classification) and two others located in rural site (sparsely built or open-set and lightweight lowrise according LCZ classification). Also these stations must be close by distance (less than 100 km) and altitude. Therefore, first for Astana city were obtained numerical evaluations for UHI climate dynamics, UHI dependence of synoptic situations and total UHI climatology on monthly and daily averages.

    Full Text Available Advertising is a phenomenon that has helped to model societies during the last century. In order to know how it has participated in some change processes it is essential to analyse its communicative dimension. Within the theoretical framework of the History of Social Communication, this research studies the function of the commercial discourse during the Spanish Civil War. Results in three levels have been concluded with an analytic model focused on the messages spread in the press. First, the modern evolution of the advertising technique is confirmed. Second, the different alignment of advertising is compared with the propagandistic discourse of each faction, as well as with its ideological and commercial interests, and with the different relationship with consumers about events. Third, advertisements allow us to observe many details about current life better than the information censored does; specifically, the struggle to survive in the most damaged republican cities is clearly perceived. - Traducción supervisada por la Dra.

  1. Disappointed "Heirs" as a Socio-Legal Phenomenon

    2014-04-01

    Full Text Available This paper focuses on the socio-legal characteristics of succession battles, drawn from a large-scale empirical study of contemporary inheritance and probate procedures and conflicts in Israel. The study shows that litigating disappointed "heirs", i.e. people who challenge the division of the estate because their inheritance hopes have been shattered, are an exception to the rule of undisputed probate and administration of estates. Moreover, the findings point to the will as a risk factor which allows disappointed "heirs" to approach the court, while legal disputes in intestate cases are even scarcer. Based on the findings, the paper also offers a typology of the relational triangles – between the deceased, the alleged heirs, and the disappointed "heirs" - which characterize most of the cases studied. This typology is correlated to the finding that most succession conflicts are not among nuclear family members, but among parties who are remote relatives or with no family relation. Finally, the study documents two dominant outcomes of succession battles: out-of-court compromises that do not respect the prima facie deceased's last wishes; and the irreversible destruction of relationships between siblings. The paper ends with a discussion of the sociological question concerning the possible increase or decrease of the phenomenon of disappointed "heirs", and of the legal implications of the study's findings. Este artículo se centra en las características sociojurídicas de las disputas de sucesión, obtenidas a partir de un estudio empírico a gran escala de los procedimientos contemporáneos de herencias y sucesiones y los conflictos en Israel. El estudio demuestra que los “herederos” decepcionados que litigan, es decir, las personas que cuestionan la división de los bienes porque no se han colmado sus expectativas, son una excepción a la regla de las sucesiones y administración de bienes sin disputas.

    To investigate the correlation between the frequency of dawn phenomenon and obesity in patients with type 2 diabetes. This study was conducted in 98 patients with type 2 diabetes admitted to the Metabolic Disease Hospital of Tianjin Medical University from 2011 to 2014. The subjects were divided into 3 groups according to BMI: the normal weight (BMI 18.5-23.9 kg/m(2), n = 30), the overweight(BMI 24-27.9 kg/m(2), n = 33)and the obesity (BMI ≥ 28.0 kg/m(2), n = 35). All participants underwent continuous glucose monitoring for 72 h. Fasting plasma glucose(FPG), insulin and C-peptide were tested. Frequency of dawn phenomenon among the 3 groups was calculated, and the correlations between dawn phenomenon and its related factors were analyzed. The frequency of dawn phenomenon in type 2 diabetes increased with the increase of BMI in the 3 groups (P obesity groups, respectively. The dawn phenomenon was positively correlated with BMI (r = 0.424, P fasting C-peptide (r = 0.254, P 0.05). The dawn phenomenon is closely associated with obesity and insulin resistance. The frequency of dawn phenomenon increases with BMI.

Results. The deja vu phenomenon occurred with cryptogenic and symptomatic focal epilepsy with equal frequency; however, the phenomenon was also seen in the idiopathic generalized form of the latter and could be concurrent virtually with any types of seizures and observed as an individual seizure and in the structure of a partial and secondarily generalized seizure. In epileptic patients, the main clinical characteristics of the deja vu vu phenomenon are its frequency, fear before its onset, and emotional coloring. The most important criterion is a change in the characteristics of deja vu vu: prolongation, more frequencies, and the emergence of negative emotions. On EEG, the phenomenon was characterized by the onset of polyspike activity in the right temporal leads and, in some cases, ended with slow-wave, theta-delta activity in the right hemisphere.

    The transformation stasis phenomenon of bainite formation in low-carbon steel was detected using a high-resolution dilatometer. The phenomenon occurred at different stages for different isothermal temperatures. In combination with microstructural observation, the calculated overall activation energy of transformation and interface migration velocity shed new light on the cause of formation of the stasis phenomenon. The temporary stasis formed at the initial stage of phase transformation for high isothermal temperature was attributed to the drag effect of substitutional atoms, which leads to low-interface migration velocity and large overall activation energy.

    2005-01-01

    An oscillation phenomenon of the low frequency reverberation intensity was observed in several shallow water reverberation experiments. This phenomenon cannot be explained by the widely used incoherent reverberation theory. In this paper, to explain the observed oscillation phenomenon, a normal mode based coherent reverberation theory is presented. The theoretical analysis and numerical results show that modal interference can cause the regular oscillation phenomenon of the low frequency reverberation intensity, and the oscillation frequency is determined by the normal mode eigen-values. A new method to estimate the bottom sound speed based on the oscillation frequency of reverberation intensity was presented in this paper. The experimental results at three different sites indicate that the bottom sound speed estimated from the oscillation frequency of reverberation intensity agrees with that inverted from Matched Field Processing (MFP) well.

  1. Oxidative stress and mechanisms of ochronosis in alkaptonuria.

    Braconi, Daniela; Millucci, Lia; Bernardini, Giulia; Santucci, Annalisa

    2015-11-01

    Alkaptonuria (AKU) is a rare metabolic disease due to a deficient activity of the enzyme homogentisate 1,2-dioxygenase (HGD), involved in Phe and Tyr catabolism. Due to such a deficiency, AKU patients undergo accumulation of the metabolite homogentisic acid (HGA), which is prone to oxidation/polymerization reactions causing the production of a melanin-like pigment. Once the pigment is deposited onto connective tissues (mainly in joints, spine, and cardiac valves), a classical bluish-brown discoloration is imparted, leading to a phenomenon known as "ochronosis", the hallmark of AKU. A clarification of the molecular mechanisms for the production and deposition of the ochronotic pigment in AKU started only recently with a range of in vitro and ex vivo human models used for the study of HGA-induced effects. Thanks to redox-proteomic analyses, it was found that HGA could induce significant oxidation of a number of serum and chondrocyte proteins. Further investigations allowed highlighting how HGA-induced proteome alteration, lipid peroxidation, thiol depletion, and amyloid production could contribute to oxidative stress generation and protein oxidation in AKU. This review briefly summarizes the most recent findings on HGA-induced oxidative stress in AKU, helping in the clarification of the molecular mechanisms of ochronosis and potentially providing the basis for its pharmacological treatment. Future work should be undertaken in order to validate in vivo the results so far obtained in in vitro AKU models. Copyright © 2015 Elsevier Inc. All rights reserved.

    Psoriasis is a chronic, immune-mediated inflammatory and refractory disease. The koebner phenomenon, which can be induced by trauma, is common in psoriasis patients. Herein, we report a patient with psoriasis who was treated by cupping therapy and subsequently developed the koebner phenomenon (KP) at the cupped sites. To our knowledge, it is the first report about cupping therapy leading to KP in a psoriasis patient.

    Acute exacerbation of symptoms during the inter-appointment time interval of endodontic treatment is a well-known complication. The phenomenon is termed "flare-up" by most researchers and clinicians, although the exact definition of it differs from one author to another, making it difficult to compare the results of the studies. The suggested flare-up index may be the way to build a common language that will enable the dental community to measure and study more of this phenomenon.

  4. The measurement problem in quantum mechanics: approximation to the phenomenon of decoherence by operational identities

    1996-01-01

    An approach based on bits and pieces of standard wisdom plus and operational quantum mechanical identity deduced by the author is presented here in order to convey arguments concerning the quantum theory of measurement and which betray a flavor against completive claims for quantum mechanics. Special emphasis is put on the phenomenon of decoherence. This phenomenon (which is experimentally verifiable) finds natural room within the formalism while the wave function collapse (which is not) is precluded. (Author)

    The presented study was impulse d by outbreak of alopecia (baldness) in children if Sillamaee in the first half of 1989 (the total number of cases was about 200, mainly infants at kindergartens, where the occurrence reached 8%). In the study, carried out during 1990, an essential environmental contamination with products of burning and processing of oil shale, especially with trace elements, in North-East Estonia, was ascertained. An increased occurrence of different health disturbances in children from the above region (Narva, Sillamaee, Kohtla-Jaerve) compared to Tartu (a town in central Estonia with less environmental contamination) was observed. The health disturbances have been expressed in increased amounts of pollutants in the organism (Pb, Cd, F, Zn, Mn, Se), in more frequent occurrence of skin and hair pathology (baldness has been observed in 2.3 to 2.4% of preschool children in Sillamaee and Narva), allergy, deviations from normal development and health of teeth, skeleton and cardio-vascular system, pre anemia and anemia, inflammations, health disturbance due to the unhealthy way of life (deficiency of physical activity, over feeding). It is obvious that environmental contamination, as well as the deficiency of certain trace elements and other compounds in the food and/or drinking water, violations of individual hygiene or sanitary instructions at kindergartens and schools and the unsuitable way of life may be considered the causal e factors in the incidence of health disturbances in children of North-East Estonia although in different proportions depending on the character of health disturbances. The products of burning and processing of oil shale which contaminate the environment, are regarded as the plausible cause of increased occurrence of baldness in children in North-East Estonia.

    Full Text Available Preliminary research on the glass ceiling phenomenon in accounting and financial audit practice in Poland The paper analyzes the glass ceiling phenomenon in the accounting practice in Poland. The essence and characteristics of this phenomenon are presented in relation to the accounting profession and statutory auditors. Research on the ‘glass ceiling’ carried out in various countries, with a particular reference to the profession of a statutory auditor, was reviewed. The paper presents results of the research on the phenomenon conducted among a selected sample of audit firms in Poland. The results of the study confirmed the occurrence of this phenomenon in Poland with greater intensity in larger entities. The large scale of the glass ceiling phenomenon in the professional life of women in accounting is reflected by a high percentage of women in the profession of statutory auditor contrasted by the very low participation in senior managerial positions, e.g. partners in auditing companies. The paper uses the method of critical analysis of the literature and empirical data. Moreover, qualitative analysis was used for the data reported by audit firms

    Dust is an atmospheric phenomenon that causes adverse environmental effects. It is deemed to have harmful effects on health, economics, and climate. This study aimed to analyze the content published on the phenomenon of dust in the widely circulated newspapers in Iran. We investigated the content of all national and provincial newspapers that were published between July and August 2014. Data on the materials related to the dust phenomenon in the newspapers were categorized and coded. From a total of 510 newspaper issues, 143 articles were devoted to the dust phenomenon which 74.1% of them were published in provincial newspapers. Among the national newspapers, Hamshahri newspaper with 16 headlines and from the provincial newspapers; Karoon with 23 headlines published the highest number of articles on dust phenomenon. 45.5% of content on dust were printed on the first page of the newspapers. The most common approach to the type of content published in these newspapers was an interview. Moreover, we noticed that 28.7% of the content published in the newspapers was related to the health issue. The media plays an important role in the transmission of health information. Weaknesses in addressing the causes of dust occurrence and also in providing solutions for the dust control and prevention were noticeable in the content published in the newspaper. It seems necessary to take practical measures to disseminate relevant information to dust and also address the needs of the target audience community influenced by the dust phenomenon properly.

    In this paper, fatigue strength of laser welded butt joint has been investigated. In order to obtain the influence of underfill and pitting, fatigue test was conducted with different sheet thickness and mechanical properties. Fatigue crack initiated at underfill and pitting in the weld metal. Stress concentration factor and hardness of the weld metal were considered to estimate fatigue limit. However, hardness of the weld metal has no significant effect on fatigue strength. As a result, fatigue strength was well estimated by hardness of base metal and stress concentration factor calculated from the shape of underflll and pitting. 7 refs., 9 figs., 5 tabs.

    1997-12-01

    This paper explains development and examples of application of automated welding devices from a viewpoint of an element technology constituting computer integrated manufacturing (CIM), based on the history of modernization of shipyards that has been achieved to date. In the first step of promoting the modernization, elevating cutting accuracy in the uppermost stream process was thought a starting point of rationalization. What have been achieved therefrom are adoption of the most advanced NC plasma cutting machine, and improvement in the computer aided system for the cutting machines. In addition, a twenty-electrode line welder has been developed, which does not create angle deformation in welding longerons, and can be operated even by unskilled workers. The welder has successfully realized a construction method in which robots can be applied more easily. Further developments have been made on a robot to weld cells, advanced CAD/CAM operation techniques which are linked with data from design, an automatic one-side welding device which can achieve a speed 2.5 times greater than by conventional devices, and an automation device for three-dimensionally bent blocks, whose automation has been regarded difficult. 11 figs., 1 tab.

    Large-scale ships such as VLCC are built at the Kure No.1 Works of IHI (Ishikawajima-Harima Heavy Industry). This paper introduces current status of mechanized and robotized welding at the works. For the sub-assembly with short weld length and horizontal fillet, simplified automatic welders are used in which mag-welding method using CO2 is adopted. The frequent wound welding of member ends can be automatically conducted using welders developed by IHI. In the large-scale assembly processes, remarkable rationalization and highly accurate assembly of flat plate welding have been promoted. Tankers, container ships, and bulk carriers can be treated at the same time. Teaching times of welding robots can be greatly reduced by a technique called parametric treatment. In the future, it is essential to enhance the accuracy of members by introducing the laser cutting during machining processes. Completely self-type mechanization is required as well as large-output laser welding and sensor technology. 3 refs., 12 figs., 2 tabs.

  15. The Psychophys behind the “Banariu visual phenomenon” - A particular case of Entoptic Phenomenon

    2016-11-01

    Full Text Available To describe the psychophysics behind the Banariu visual phenomenon is a delight. Scientifically, a phenomenon is any event that is observable. In this case we will be describing an entoptic phenomenon (ent means within and optic means the eye. Before starting to experience the phenomenon, ask yourself: Does the eye lie? It is certainly undeniable that it does not, anyway, not voluntarily. Even if it may not lie, it does not mean that for a moment at least it can’t be lied to. In this case the patient suddenly experiences dizziness and a feeling of falling on his back accompanied by a brief moment of slight brightness. Because of this “brightness”, it is obvious that Banariu visual phenomenon is a particular case of Phosphene. In fact, Phosphene appears as the movement of multiple light sensations. But that Banariu visual phenomenon when expressed, at least in descriptions, gives the illusion of light growth. This will generate the sensation of falling, especially when the head is tilted back to look upward. These clinical observations have led to the working out of a method to establish when the phenomenon occurs, but it relies basically on the sincerity of the subject analyzed (Banariu method. In this method the subject studied is asked to look up quickly at a fixed point which should preferably be at the equivalent height of a second or third floor of a building. Meanwhile, a medical team should be standing behind the patient to catch him if he falls back.

    The concept of the waterfall phenomenon in Zone 2 in the pulmonary vasculature is well known from West's lung model. It is believed that the flow through this zone is determined by the pressure difference between the pulmonary artery and alveoli, and the left atrial pressure is not transmissible to the alveolar capillaries. However, it is impossible to see whether alveolar capillaries are really displaying the waterfall phenomenon or not. In this review, the interrelation between the flow and geometry of the alveolar capillaries in the waterfall phenomenon is analyzed based on physiological studies using a model system and isolated lung lobe experiments. Further, extending the concept to the analysis of ventilatory changes of the inferior vena cava (IVC) configuration, it is ascertained that the waterfall phenomenon normally occurs in the IVC during inspiration just before it enters the thorax and the waterfall phenomenon in the IVC disintegrates with elevation of the central venous pressure. Because these configurations of the IVC in normal and abnormal conditions are visible with ultrasonography, the technique is very useful as a noninvasive approach to diagnose right heart failure.

  17. CONSIDERATIONS ON THE PHENOMENON OF DOUBLE TAXATION IN THE EUROPEAN UNION

    Full Text Available In the general context of economic globalization, international economic cooperation, the liberalization movement of goods, services, capital and persons, and the effect of the exercise of fiscal sovereignty, appears the phenomenon of double or multiple international taxation of income and assets, following the vocation of several legal systems, which contain legislative differences and can generate tax obstacles, such as, the laws of the country of origin of the revenue and the legislation of the country of destination of income. Thus, more interesting becomes the study of the phenomenon of double taxation at EU level given the distinct presence of 27 sovereignties in full process of European integration So, this paper aims to identify how the European Union handles the phenomenon of double taxation, making a shift from defining this phenomenon to identifying the legislation designed to avoid or eliminate the phenomenon of double taxation in the field of EU direct taxation.Also, this paper deems necessary to stop a moment upon the fiscal harmonization and integration in the indirect taxation field of the European Union.

  18. The influence of initial conditions of water-entry on ricochet phenomenon

    The ricochet phenomenon of the water-entry of the water–air crossing vehicle is investigated by both experiments and numerical simulations. Experiments and numerical simulations of the water-entry process with different inclination angles, velocities, and attack angles are performed. The whole ricochet progress and the changing rules of angular acceleration, angular velocity, and displacement are obtained and analyzed by numerical simulation for a deeper understanding of ricochet phenomenon. The experiment is carried out to study the underwater trajectory by changing the initial condition only. The experimental results are in good agreement with the simulations. The results show that: (1) A small inclination angle causes the trajectory to bend upward, favoring the ricochet phenomenon. (2) A large velocity value also favors the ricochet phenomenon, making it occur more easily and quickly, but lower velocities are insufficient to provide the necessary kinetic energy. (3) The ricochet phenomenon is more likely to occur under a negative attack angle that causes the trajectory to bend upward, but a positive angle balances the underwater trajectory. These results can provide guidance to design a new water–air cross vehicle. (paper)

    This paper summarizes phenomenology and discusses how nurses can use their own experiences as data and maintain rigour within the method. It explores how data from researchers experiencing the phenomenon of interest could be used to explicate assumptions and pre-understandings and may also be used as data. While the ethnographic concept of insider research has gained popularity, the notion of researcher as participant in phenomenology is relatively new. The lived experience of a phenomenon is unique to each person and utilization of the nurse researcher's experiences of the phenomenon should be considered for inclusion as data. Discussion paper. Articles from 2001 - 2015 in the CINAHL and PubMed databases were identified using keywords such as 'insider research', 'phenomenology', 'bracketing' and 'qualitative research'. In addition, reference lists from articles used were examined to identify additional literature. Phenomenology is a valuable research method. Usability, credibility, trustworthiness and auditability of data collected must be considered to ensure rigour and maintain orientation to the phenomenon under investigation. Nurse researchers may be interviewed as participants if these four principles are considered and methods used are made explicit. Utilizing appropriate research methods are as important as getting clinical practice correct to advance knowledge and benefit those under our care. We recommend using the researchers' experience as a data source to gain a complete picture of the phenomenon under investigation. Using the approach proposed here, nurses can ensure they are incorporating all data sources available while maintaining research rigour. © 2016 John Wiley & Sons Ltd.

    Full Text Available Cement-based composite materials have minimum of two components, one of which has higher strength compared to the other. Such materials include concrete, reinforced concrete (RC, and ferrocement, applied in single- or two-layer RC elements. This paper discusses experimental and theoretical results, obtained by the authors in the recent three decades. The authors have payed attention to a structural phenomenon that many design features (parameters, properties, etc. at ultimate limit state (ULS of a structure are twice higher (or lower than at initial loading state. This phenomenon is evident at material properties, structures (or their elements, and static and/or dynamic structural response. The phenomenon is based on two ideas that were developed by first author: quasi-isotropic state of a structure at ULS and minimax principle. This phenomenon is supported by experimental and theoretical results, obtained for various structures, like beams, frames, spatial structures, and structural joints under static or/and dynamic loadings. This study provides valuable indicators for experiments’ planning and estimation of structural state. The phenomenon provides additional equation(s for calculating parameters that are usually obtained experimentally and can lead to developing design concepts and RC theory, in which the number of empirical design coefficients will be minimal.

    2015-12-01

    Full Text Available Transnationalism as both a phenomenon and a concept has received negligible attention in modern times in relation to the practice of public administration and its corresponding field of study. This article provides an account of the meaning and the relevance of both the concept and phenomenon as received and applied by practitioners and scholars in the said practice and field of study. From the latter, a deliberate approach towards policy matters is undertaken in relation to the concept and phenomenon of transnationalism. In this article policies used by the national Department of Home Affairs in South Africa form the basis from which a case is made relevant to this topic in p(Public a(Administration. Additionally, case studies in the SADC region are considered. This article therefore argues that transnationalism is as much local as global issues such as immigration, citizenship, global economy, service delivery, government (inefficiency and (ineffectiveness and such other matters of public interest.

    The use of multidetector computed tomography (MDCT) in routine abdominal explorations has increased the detection of the nutcracker phenomenon, defined as left renal vein (LRV) compression by adjacent anatomic structures. The embryology and anatomy of the nutcracker phenomenon are relevant as a background for the nutcracker syndrome, a rare cause of hematuria as well as other symptoms. MDCT examples of collateral renal vein circulation (gonadal, ureteric, azygous, lumbar, capsular) and aortomesenteric (anterior) and retroaortic (posterior) nutcracker phenomena in patients with no urologic complaint are shown as well as studies performed on patients with gross hematuria of uncertain origin. Incidental observation of collateral veins draining the LRV in abdominal MDCT explorations of asymptomatic patients may be a sign of a compensating nutcracker phenomenon. Imbalance between LRV compression and development of collateral circulation may lead to symptomatic nutcracker syndrome. (orig.)

    2012-01-01

    Radiation recall phenomenon is a tissue reaction that develops throughout a previously irradiated area, precipitated by the administration of certain drugs. Radiation recall is uncommon and easily neglected by physicians; hence, this phenomenon is underreported in literature. This manuscript reports two cases of radiation recall. First, a 44-year-old man with nasopharyngeal carcinoma was treated with radiotherapy in 2010 and subsequently developed multi-site bone metastases. A few days after the docetaxel-based chemotherapy, erythema and papules manifested dermatitis, as well as swallowing pain due to pharyngeal mucositis, developed on the head and neck that strictly corresponded to the previously irradiated areas. Second, a 19-year-old man with recurrent nasal NK/T cell lymphoma initially underwent radiotherapy followed by chemotherapy after five weeks. Erythema and edema appeared only at the irradiated skin. Both cases were considered chemotherapeutic agents that incurred radiation recall reactions. Clinicians should be knowledgeable of and pay attention to such rare phenomenon

    Full Text Available We describe a 59-year-old female who presented with ischaemic digits, preceded by a 6-month history of Raynaud’s phenomenon affecting her fingers and toes. There were no clinical or laboratory features of primary vasculitis or connective tissue disease, Doppler imaging was normal, and bloods were unremarkable aside from a platelet count of 786 × 109/L (150–400 and white cells of 16 × 109/L (4–11. In view of the thrombocytosis a JAK2 mutation assay was requested which confirmed a JAK2 V617F mutation, suggesting essential thrombocytosis (ET as the cause. She received treatment with hydroxycarbamide which normalised her platelet count and led to a complete resolution of her Raynaud’s symptoms. Raynaud’s phenomenon is a rare manifestation of ET. Myeloproliferative disorders such as ET should be considered in the differential diagnosis of Raynaud’s phenomenon and vasculitis.

    2016-12-01

    Full Text Available This sociolinguistics study investigates a new phenomenon that has recently surfaced in the field of code-switching among Saudi females residing in the Western region of Saudi Arabia. This phenomenon basically combines bound Arabic pronouns, tense markers or definite article to English free morphemes or the combination of bound English affixes to Arabic morphemes. Moreover, the study examines the factors that affect this type of code-switching. The results of the study indicate that this phenomenon provides data that invalidates Poplack’s (1980 universality of the ‘Free Morpheme Constraint’. It is also concluded that the main factors that influence this type of code-switching is solidarity and group identity among other factors.

    Full Text Available In this article we examine the influence of the leadership style on the resistance to change phenomenon, as well as how the degree of resistance to change differs in private organizations versus public ones. After analyzing the literature and conducting a survey in Romanian organizations we have concluded that the leadership style adopted by a top manager has an important impact on employees resistance to change. The research was designed to inform practitioners, researchers, managers and other interested persons about the influence of the leadership style on the resistance to change phenomenon, as well as how the phenomenon is manifested in different types of organizations. The main contribution of this paper is that in order to benefit of a lower degree of resistance to change from employees, the participative leadership style is recommended to be applied.

  8. Contribution to the study of the latch-up phenomenon in CMOS technologies

    International Nuclear Information System (INIS)

    Leroux, Charles

    1988-01-01

    The latch-up phenomenon is due to the presence of a parasite PNPN structure between a circuit supply and the ground. This structure may pass from its usual high impedance state to a low impedance state (few Ohms). The author reports the development of a test methodology able to identify this phenomenon. An analytic model has been developed which takes several issues into account: the three-dimensional aspect of resistances of this structure, the strong injection and its consequences. A new element is introduced which allows the phenomenon retention. This model without adjustment parameter gives good results with respect to experiment. A strategy of optimisation of these technologies with respect to the latch-up effect has also been defined. It leads to the production of a batch for which structures with a low insulation distance between sources of transistors of opposite type (four microns) display a hold voltage greater than the supply voltage (five volts) [fr

    2009-09-01

    Lucio's phenomenon is a rare and aggressive necrotising variant of erythema nodosum leprosum that classically occur in patients with undiagnosed, diffuse non-nodular lepromatous leprosy. It is a potentially fatal leprosy reaction characterised by extensive, bizarrely-shaped, painful purpuric skin lesions and ulcerations. Lucio's phenomenon is very rarely reported outside of Mexico and Costa Rica. We describe 3 cases seen in Johor, Malaysia. The first two cases responded to the prompt simultaneous institution of daily rifampicin, dapsone, clofazimine and prednisolone. Case 3 continued to have new lesions and extension of existing lesions while on dapsone and clofazimine. The subsequent addition of rifampicin and prednisolone prevented new lesion formation but patient succumbed to the extensive cutaneous infarcts and consequent sepsis. Early diagnosis and prompt institution of multi-drug therapy together with prednisolone may improve the prognosis and outcome of Lucio's phenomenon.

    Goleman, Michael J

    2011-01-01

    During the 1970s many small-scale cattle ranchers across the Midwest reported finding their cattle mutilated. The episode, often dismissed as mass hysteria or sensationalized reporting, demonstrates the growing dissatisfaction of many ranchers concerning government intrusiveness and restrictive policies. These frustrations found a release in response to the mutilation phenomenon during which ranchers vented their anger by taking direct aim at the federal government. The turbulent economic conditions of the period paired with government interference in the cattle industry helped sustain the mutilation phenomenon as ranchers projected their fears and insecurities through the bizarre episode. The hostility ranchers showed toward the federal government during the mutilation scare presaged and helped provide the impetus for events such as the Sagebrush Rebellion. The mutilation phenomenon also underscores the pronounced effects of the libertarian movement of the 1960s that gave rise to the New Right and gained adherents across the West and Midwest.

    2017-04-01

    The pivot shift test is performed in different techniques and the rotation of the tibia seems to have a significant impact on the amount of the pivot shift phenomenon. It has been hypothesised that external rotation will increase the phenomenon due to less tension at the iliotibial band in knee extension. Twenty-four patients with unilateral anterior cruciate ligament insufficiency were included prospectively. The pivot shift test was performed bilaterally in internal and external tibial rotation under general anaesthesia. Knee motion was captured using a femoral and a tibial inertial sensor. The difference between positive and negative peak values in Euclidean norm of acceleration was calculated to evaluate the amount of the pivot shift phenomenon. The pivot shift phenomenon was significantly increased in patients with ACL insufficiency when the test was performed in external [mean 5.2 ms - 2 (95% CI 4.3-6.0)] compared to internal tibial rotation [mean 4.4 ms - 2 (95% CI 3.5-5.4)] (p = 0.002). In healthy, contralateral knees did not show any difference between external [mean 4.0 ms - 2 (95% CI 3.3-4.7)] and internal tibial rotation [mean 4.0 ms - 2 (95% CI 3.4-4.6)] (ns). The pivot shift phenomenon was increased with external rotation in ACL-insufficient knees, and therefore, one should perform the pivot shift test, rather, in external rotation to easily evoke the, sometimes difficult to detect, pivot shift phenomenon.

  12. A new type of interference phenomenon in cold collisions of electrons with N2

    DEFF Research Database (Denmark)

    Sulc, Miroslav; Curik, Roman; Ziesel, Jean-Pierre

    2011-01-01

    A novel cold collision phenomenon is described which is caused by interference within the manifold of electron waves of unit angular momentum (p-waves). Experimental electron scattering data in N2, down to energies of 10 meV, reveal this phenomenon through the angular distribution of scattered...... electrons. Ab initio theory, analytical results and a simple physical model illustrate how interference arises through the presence of a quadrupole on the target N2. The effect is of a general nature and may be found in all systems in which, in the cold regime, charged particles interact with target species...

    Full Text Available The paper Empirical reflections on migration phenomenon. Major effects of migration on the human capital analyzes the migration flows of the workforce (as part of the human capital globally/regionally, especially the highly qualified workforce migration. The qualified manpower processes of attracting on the work market have not been always well understood and, in some cases, have generated a series of difficulties. This is the reason why we will focus on the „waste of brains” phenomenon, which appears when highly qualified individuals are neither employed in the source-country nor in the target country; and, if they are, their job is below their qualifications.

  15. Prevalence Rates of the Incubus Phenomenon: A Systematic Review and Meta-Analysis

    Directory of Open Access Journals (Sweden)

    Marc L. Molendijk

    2017-11-01

    Full Text Available BackgroundThe incubus phenomenon is a paroxysmal sleep-related disorder characterized by compound hallucinations experienced during brief phases of (apparent wakefulness. The condition has an almost stereotypical presentation, characterized by a hallucinated being that exerts pressure on the thorax, meanwhile carrying out aggressive and/or sexual acts. It tends to be accompanied by sleep paralysis, anxiety, vegetative symptoms, and feelings of suffocation. Its prevalence rate is unknown since, in prior analyses, cases of recurrent isolated sleep paralysis with/without an incubus phenomenon have been pooled together. This is unfortunate, since the incubus phenomenon has a much greater clinical relevance than isolated sleep paralysis.MethodsPubMed, Embase, and PsycINFO were searched for prevalence studies of the incubus phenomenon, and a meta-analysis was performed.ResultsOf the 1,437 unique records, 13 met the inclusion criteria, reporting on 14 (k independent prevalence estimates (total N = 6,079. The pooled lifetime prevalence rate of the incubus phenomenon was 0.19 [95% confidence interval (CI = 0.14–0.25, k = 14, N = 6,079] with heterogeneous estimates over different samples. In selected samples (e.g., patients with a psychiatric disorder, refugees, and students, prevalence rates were nearly four times higher (0.41, 95% CI = 0.25–0.56, k = 4, n = 1,275 than in the random samples (0.11, 95% CI = 0.08–0.14, k = 10, n = 4,804. This difference was significant (P < 0.001.ConclusionThis review and meta-analysis yielded a lifetime prevalence of the incubus phenomenon in the general population of 0.11 and, in selected samples, of 0.41. This is slightly higher than the prevalence rates in previous analyses that included cases of recurrent isolated sleep paralysis without an incubus phenomenon. Based on the condition’s robust clinical presentation and the relatively high prevalence rates, we advocate

    One surprising feature of cognitive and emotional development in the moral domain is the so-called happy victimizer phenomenon, which is commonly explained by a lack of moral motivation. Concerning this general approach, there are two pieces of news in this chapter. The bad news is that moral motivation is a highly problematic concept and its purported theoretical role in moral functioning untenable. The good news is that the happy victimizer phenomenon can be explained without reference to something like "moral motivation." © Wiley Periodicals, Inc.

  17. On the explaining-away phenomenon in multivariate latent variable models.

    van Rijn, Peter; Rijmen, Frank

    2015-02-01

    Many probabilistic models for psychological and educational measurements contain latent variables. Well-known examples are factor analysis, item response theory, and latent class model families. We discuss what is referred to as the 'explaining-away' phenomenon in the context of such latent variable models. This phenomenon can occur when multiple latent variables are related to the same observed variable, and can elicit seemingly counterintuitive conditional dependencies between latent variables given observed variables. We illustrate the implications of explaining away for a number of well-known latent variable models by using both theoretical and real data examples. © 2014 The British Psychological Society.

  18. Problems posed by the development of the Oklo phenomenon: tentative global interpretation

    International Nuclear Information System (INIS)

    Naudet, R.

    This paper discusses the basic problems posed by the development of the Oklo phenomenon: the conditions in which the reactions are triggered and propagated and how they have been controlled. The reactions were maintained by the destruction of neutron poisons in the ore and were controlled by temperature. Oklo is made up of a large number of contiguous reactors. Geological problems of the origin of the clays, desilification, and uranium concentration are discussed. Oklo is shown to be a very complex phenomenon which developed in space and time. Besides the thermal, neutron, and geochemical coupling, there is also a tectonic coupling

    2013-12-01

    Full Text Available The article revealed contents of the phenomenon of transforming love in the work of Dostoevsky on the materials of the novel «The Idiot». Many philosophic studies were devoted to the problem of analysis of the phenomenon of love in the works of F.M. Dostoyevsky. Most researchers emphasize the sacrificial (agapic love, or focuses on erotic nature of love. This approach significantly constricts the phenomenon of love described by the writer in the form of Prince Myshkin. The study of love of Prince was carried out using four concepts covering the four key aspects of love: eros, agape, philia and storge. Thus, there are main features of love­eros of Prince Myshkin, such as: drive for beauty and its admiration, ardor and impetuosity, recklessness and frenzy, which are positive, i.e. they are the evidence that his love­eros was hierarchically focused on more exalted goods. Love­agape is in the center of the phenomenon of transforming love with its pity, compassion, sacrifice, care and forgiveness. Love­philia is demonstrated in Prince Myshkin by similarity of views, common ground, mutual understanding, trust and love­storge – by affection causing peace of mind or depression. Thus, the study proved that Prince Myshkin is an ideologist of transforming love, combining all four aspects of it. Creativity, the ability to change spiritually not only the love medium but also the people around is the evidence of his transforming love.

    2018-02-01

    Zonal disintegration phenomenon was found in deep mining roadway surrounding rock. It seriously affects the safety of mining and underground engineering and it may lead to the occurrence of natural disasters. in deep mining roadway surrounding rock, tectonic stress in deep mining roadway rock mass, horizontal stress is much greater than the vertical stress, When the direction of maximum principal stress is parallel to the axis of the roadway in deep mining, this is the main reasons for Zonal disintegration phenomenon. Using ABAQUS software to numerical simulation of the three-dimensional model of roadway rupture formation process systematically, and the study shows that when The Direction of maximum main stress in deep underground mining is along the roadway axial direction, Zonal disintegration phenomenon in deep underground mining is successfully reproduced by our numerical simulation..numerical simulation shows that using ABAQUA simulation can reproduce Zonal disintegration phenomenon and the formation process of damage of surrounding rock can be reproduced. which have important engineering practical significance.

  8. Jihadist Foreign Fighter Phenomenon in Western Europe: A Low-Probability, High-Impact Threat

    Directory of Open Access Journals (Sweden)

    Edwin Bakker

    2015-11-01

    Full Text Available The phenomenon of foreign fighters in Syria and Iraq is making headlines. Their involvement in the atrocities committed by terrorist groups such as the so-called “Islamic State” and Jabhat al-Nusra have caused grave concern and public outcry in the foreign fighters’ European countries of origin. While much has been written about these foreign fighters and the possible threat they pose, the impact of this phenomenon on Western European societies has yet to be documented. This Research Paper explores four particular areas where this impact is most visible: a violent incidents associated with (returned foreign fighters, b official and political responses linked to these incidents, c public opinion, and d anti-Islam reactions linked to these incidents. The authors conclude that the phenomenon of jihadist foreign fighters in European societies should be primarily regarded as a social and political threat, not a physical one. They consider the phenomenon of European jihadist foreign fighters a “low-probability, high-impact” threat.

  10. An investigation for identification of factors governing F and P phenomenon

    International Nuclear Information System (INIS)

    Ray, M.K.S.; Saini, R.D.; Kutty, K.K.; Das, D.

    1992-01-01

    A series of experiments were carried out in divided electrolytic cells in an attempt to identify factors governing the occurence of Fleischmann and Pons (F and P) phenomenon. Despite wide variation in operating parameters (cathode characteristics, type and concentration of electrolyte) and perturbation of deuterated cathodes and sharp change in their temperatures, experiments yielded no evidence of the phenomenon even though high loading (sometimes upto D/Pd ∼2) could be achieved repeatedely. However, large excess heat liberation, not accountable by probable physicochemical processes, was observed following perturbation of the state of equilibrium of a deuterated cathode (having a portion of it free of scale and bright in appearance) by air. Instances of anomalies in tritium distribution between gas and liquid phase resulting from such perturbation were also noticed. These observations, when analysed in global perspective, clearly indicate the essentiality of oxygen and scale free surface for occurrence of the phenomenon. Study of desorption dynamics and related parameters revealed that the overall effect of oxygen is to enhance the escaping tendency of deuterium from Pd lattice and that the phenomenon is in someway related to desorption. Significant increase in tritium activity in gas phase observed following repeated perturbation of deuterated cathode by induced pulsed magnetic field is suggestive of a possible mechanism in which strong electron affinity of oxygen is of paramount importance.

  18. The Phenomenon of Touch in Architectural Design and a Field Study on Haptic Mapping

    Directory of Open Access Journals (Sweden)

    Pınar ÖKTEM ERKARTAL

    2015-02-01

    Full Text Available Ocular-centrism is the utilitarian-aesthetic perspective which dominates the perception of spatial quality and architectural success in the West. In locating vision as the dominant discourse in architectural design, this perspective has been criticized for ignoring the physical and psychological relation created between subject and space during the spatial experience, sensual memory, movement and time. The phenomenon of touch, which may be defined as the interaction between architecture and subject dependent on physical and cognitive perception, offers another way of thinking and interpreting architecture, and constitutes an alternative starting point for design. The aim of this study was three-fold: to research and describe the phenomenon of touch in design concepts, to present the effects of hapticity in spatial experience on the user, and to present a visualization study for this phenomenon which is quite challenging to express. For the fieldwork, five buildings designed by Peter Zumthor were chosen. Zumthor stresses the importance of sensation, materiality and atmosphere in the architectural design process. Zumthor’s abstract design elements, their use in architectural space and the effect were determined using physical measurement. The findings were represented in “haptic mapping”. This visualization study consisted of a “haptic scatter chart”, “materiality- affect analysis” and “sensation analysis” and revealed that the phenomenon of touch and concepts identified it such as sensations, influence, materiality and mental associations are not abstract and inaccessible assumptions, but tools which can be included in the architectural design process.

    2018-02-13

    In the last 30 years, elder abuse and neglect has been recognized as a social and health-related problem. The aim of this paper is to describe the phenomenon of elder abuse and neglect in a separatist faith-based society (ultra-Orthodox Jewish society-UOJS). A qualitative-phenomenological study with 28 social workers who underwent in-depth semi-structured interviews based on an interview guide consisting of the following items: visibility of the elder abuse and neglect phenomenon in the ultra-Orthodox society, and dilemmas and sensitive issues that arise when working with this population. Three main themes emerged: (1) Between the commandment to honor one's parents and concealment patterns: Cultural barriers to exposing the abuse and neglect phenomenon; (2) "Life is demanding:" The unique expression of abusive and neglectful behavior in the UOJS; (3) Culturally related dilemmas when intervening with cases of elder abuse and neglect. Ultra-Orthodox Jewish cultural belief is a differentiating component in the context of elder abuse and neglect. Social workers need to develop a deep understanding of the unique characteristics of the phenomenon and cultural sensitivity to cope with it to address the well-being of older ultra-Orthodox Jews.

  7. Review of the Phenomenon of Ice Shedding from Wind Turbine Blades

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available Wind power is a sustainable source of energy. However, there are certain challenges to be  overcome. One of the operational challenges is the phenomenon of ice shedding. Icing happens on wind turbine blades in cold regions. When ice grows to a certain size, it separates from the wind turbine blades resulting in the phenomenon of ice shedding. This phenomenon is of significantly dangerous for equipment and personnel in the region. Ice shedding may happen either because of vibrations or bending in blades. However, it was noticed by operators at Nygårdsfjell wind park, Narvik, Norway that ice shedding is more probable to happen when blades are stopped and turned back on. This observation reveals the fact that bending of blades (from loaded to unloaded positions allows the ice to separate and hence result in ice shedding. This can be linked to the phenomenon of icing, mechanical and adhesive properties of ice. This paper reviews above in detail.

    Directory of Open Access Journals (Sweden)

    Devendra A. Sawant

    2015-01-01

    Full Text Available Nutcracker phenomenon or renal vein entrapment is classically seen as a compression of renal vein in between abdominal aorta and superior mesenteric artery with patients being asymptomatic or clinically manifested in the form of nutcracker syndrome as proteinuria, hematuria, flank pain, pelvic congestion in women, and varicocele in men. In this report, we are presenting a case of rare variant of nutcracker phenomenon along with brief review of anatomy, pathophysiology, public health, and clinical significance of nutcracker syndrome. On a routine dissection of an adult male cadaver, we noticed an unusual arrangement of the structures at the hilum of the left kidney showing entrapment of renal vein between left anterior inferior and posterior segmental renal arteries. The variation in the course of left anterior inferior segmental renal artery leads to compression of left renal vein at renal hilum. Therefore, we have named this rare abnormal anatomical entity as hilar nutcracker phenomenon. The structures in the right renal hilum are normal. The objective of this paper is to report an unusual but important variant of nutcracker phenomenon and also give collective knowledge of such anatomical variations in renal vasculature that will help in diagnosing and treating such rare renal disorder.

    Full Text Available The present paper deals with the CgA level during metastasis linked with Capacitance relaxation phenomenon in cancer cell. CgA co-stored and correlated by exocytosis with catecholamines is a precursor to peptides that exert feedback regulatory control on catecholamine secretion. It is to be noted that CgA was the most sensitive marker for detecting patients with tumor angiogenesis. The progressive rise in CgA increases with the tumor size and this fact has been correlated with the Capacitance relaxation phenomenon (T. K. Basak, US patent No. 5691178, 1997 in different stages. The experimental results of Capacitance relaxation phenomenon were given as inputs to a model for correlation with the CgA level. This model is a control system model, the output of which is the CgA level. It is to be noted that the model is simulated in MATLAB. The expression of tumorogenisis in prostate and liver is also linked to Capacitance relaxation phenomenon in respect of its correlation with the CgA level.

    The incidence of milking phenomenon is between 0.6 and 4 % in angiographic series; however, autopsy studies raise the incidence of myocardial bridges up to 85 %. This malformation goes unnoticed in most cases but can have a big impact on personal and professional level. The objective was to present an example of milking phenomenon with disability and professional consequences. Male, 44 years old, bricklayer and farmhand laborer. He referred tonsillectomy and osteoarthritis and being a smoker of 10 cigarettes per day, drinking 2-3 cups of coffee daily and 2-3 glasses of wine at the weekends. The primary care physician referred him to cardiologist with suspicion of arrhythmia. The cardiology service report mentioned electrocardiogram at sinusal rhythm, 90 beats per minute and incomplete right bundle-branch block. At ergonomics test, in the first stage of Bruce protocol, the patient's development of hypertensive crisis suggested a milking phenomenon. Finally, the diagnosis was established by angiographic studies with left common branch, circumflex coronary artery, right coronary artery and anterior descendent artery, without evidence of pathology but it was seen systolic compression on the medial segment. The case was concluded by the disability assessment team, recognizing a total permanent disability with limitations for activities requiring moderate physical efforts. The milking phenomenon diagnosis that could be related with ischemic heart disease is by angiography. Finally, the patient ended with total permanent disability.

    Full Text Available Migration represented and represents a very important phenomenon at global level, taking into consideration besides its demographic implications, its extremely diverse implications such as socio-economic, socio-cultural, territorial, or environmental. This represents, probably, the main reason why the research on migration is interdisciplinary, having strong connections with sociology, political sciences, history, economics, geography, demography, psychology, or low, among others. All these disciplines target different aspects of population migration, and a proper comprehension of the phenomenon implies a contribution from the part of all of them. Although migration represents a phenomenon manifested since ancient times, it has never been such an universal or significant phenomenon from the socio-economical or political perspective, as it is in present times. International migration has both a negative and positive impact on both provider and receiving countries, in general playing a very important role in the structure and dimension of the population of a country. Romania is not an exception to the previously expressed statement; furthermore, after the fall of the communist regime, migration became for Romania one of the most important socio-economical phenomena. The present paper aims at analyzing in a descriptive manner the international migration phenomenon in Romania between 1991 and 2008, from quantitative perspective. Based on data identified in the "Statistical Yearbook of Romania - 2008 and 2009 editions - the analysis revealed the fact that both immigration and emigration flows registered oscillatory evolutions in the analysed period, but the general trend of immigration was of increasing, while the one of emigration was of decreasing. Immigration was dominated by the presence of males, of persons aged between 26 and 40 and of persons coming from the Republic of Moldova. On the other side, in the case of emigration the significant

    Full Text Available This Research Paper explores how the foreign fighters phenomenon and terrorism more generally is repressed in Western Europe. It looks at a few specific repressive measures announced or adopted by France and the Netherlands, as well as criticism expressed against these proposals and measures. In addition to these two detailed analyses, references will also be made to other developments in Western Europe which appear to be indicative of a more general trend in which human rights increasingly seem to be put on the back seat when countering the phenomenon of foreign fighters and terrorism more generally. In the final section, a number of concluding thoughts and recommendations will be offered which explain why only a response based on human rights will be effective in countering this global problem in the long run.

    1994-01-01

    In order to improve the safety of anti-gas filters users, the Cogema (Nuclear Materials General Company) has developed a gaseous pollutants saturation detection technology for respiratory protection masks. As a matter of fact, the problem consists in studying the surface properties of a solid. In this study the adsorption has been considered as a phenomenon which can be followed by a relatively simple electrical measure technology. A microscopic description of the adsorption phenomenon has been given at first and explained by the thermodynamics laws. Then a theoretical model has been elaborated. The developments which have been brought to this model in this work have allowed to give a satisfactory interpretation of the phenomena observed during the adsorption of a polar gas on a zeolite.

    2014-08-01

    A number of biological systems can be modelled by Markov chains. Recently, there has been an increasing concern about when biological systems modelled by Markov chains will perform a dynamic phenomenon called overshoot. In this study, the authors found that the steady-state behaviour of the system will have a great effect on the occurrence of overshoot. They showed that overshoot in general cannot occur in systems that will finally approach an equilibrium steady state. They further classified overshoot into two types, named as simple overshoot and oscillating overshoot. They showed that except for extreme cases, oscillating overshoot will occur if the system is far from equilibrium. All these results clearly show that overshoot is a non-equilibrium dynamic phenomenon with energy consumption. In addition, the main result in this study is validated with real experimental data.

    Full Text Available The goal of the paper is to analysed the influence of the different types of excitation on the synchronisation phenomenon in case of the rotating system composed of a rigid hub and three flexible composite beams. In the model is assumed that two blades, due to structural differences, are de-tuned. Numerical calculation are divided on two parts, firstly the rotating system is exited by a torque given by regular harmonic function, than in the second part the torque is produced by chaotic Duffing oscillator. The synchronisation phenomenon between the beams is analysed both either for regular or chaotic motions. Partial differential equations of motion are solved numerically and resonance curves, time series and Poincaré maps are presented for selected excitation torques.

  10. Quantum eigenstates of a strongly chaotic system and the scar phenomenon

    International Nuclear Information System (INIS)

    Aurich, R.; Steiner, F.

    1993-04-01

    The quantum eigenstates of a strongly chaotic system (hyperbolic octagon) are studied with special emphasis on the scar phenomenon. The dynamics of a localized wavepacket is discussed which travels along a short periodic orbit yielding a test for the scar model developed by Heller. The autocorrelation function C(t) and the smeared weighted spectral density S τ (E) are in accordance with this model, but the conclusion that this implies the existence of scarred eigenstates is not confirmed. A random wavefunction model generates with the same probability intensity structures being localized near short periodic orbits as the wavefunctions obeying the Schroedinger equation. Although there are some eigenstates which are localized near a periodic orbit, the conclusion that their intensities differ significantly from the statistically expected ones cannot be drawn. Thus the scar phenomenon seems to be absent in the case of hyperbolic octagons. (orig.)

    2013-02-01

    Scale errors is a term referring to very young children's serious efforts to perform actions on miniature replica objects that are impossible due to great differences in the size of the child's body and the size of the target objects. We report three studies providing further documentation of scale errors and investigating the validity and robustness of the phenomenon. In the first, we establish that 2-year-olds' behavior in response to prompts to "pretend" with miniature replica objects differs dramatically from scale errors. The second and third studies address the robustness of the phenomenon and its relative imperviousness to attempts to influence the rate of scale errors. Copyright © 2012 Elsevier Inc.

    Full Text Available The Latino gangs that have come into existence in Spain represent a potential risk factor for citizens’ security and coexistence. That is the view of security forces and organisations, and it also seems to be the understanding reached by the administrations of the Autonomous Communities of Catalonia and Madrid, whose actions in the light of this phenomenon are assessed in this work. To this end, the author begins with an analysis of the significance of Latino gangs inSpain, from their origins to their introduction, and carries out a review of their current situation, including their organisation, recruitment, impact and risk for citizen security. Only with suchan analysis can one begin to comprehend the scenario of dangers that will appear in the future, and the police strategy that should be introduced to deal with the phenomenon.

  13. Collisional drag may lead to disappearance of wave-breaking phenomenon of lower hybrid oscillations

    International Nuclear Information System (INIS)

    Maity, Chandan; Chakrabarti, Nikhil

    2013-01-01

    The inhomogeneity in the magnetic field in a cold electron-ion non-dissipative homogeneous plasma leads to the breaking of lower hybrid modes via phase mixing phenomenon [Maity et al. Phys. Plasmas 19, 102302 (2012)]. In this work, we show that an inclusion of collisional drag force in fluid equations may lead to the disappearance of the wave-breaking phenomenon of lower hybrid oscillations. The nonlinear analysis in Lagrangian variables provides an expression for a critical value of damping rate, above which spikes in the plasma density profile may disappear. The critical damping rate depends on the perturbation and magnetic field inhomogeneity amplitudes as well as the ratio of the magnetic field inhomogeneity and perturbation scale lengths.

    Pinto, Yair; de Haan, Edward H F; Lamme, Victor A F

    2017-11-01

    The split-brain phenomenon is caused by the surgical severing of the corpus callosum, the main route of communication between the cerebral hemispheres. The classical view of this syndrome asserts that conscious unity is abolished. The left hemisphere consciously experiences and functions independently of the right hemisphere. This view is a cornerstone of current consciousness research. In this review, we first discuss the evidence for the classical view. We then propose an alternative, the 'conscious unity, split perception' model. This model asserts that a split brain produces one conscious agent who experiences two parallel, unintegrated streams of information. In addition to changing our view of the split-brain phenomenon, this new model also poses a serious challenge for current dominant theories of consciousness. Copyright © 2017 Elsevier Ltd.

  15. Study of the two-phase liquid loading phenomenon by applying CFD techniques

    Directory of Open Access Journals (Sweden)

    J Vieiro

    2016-09-01

    Full Text Available In order to understand the liquid loading phenomenon, 2D (axisymmetric numerical simulations were performed. This phenomenon appears when the gas velocity reduces to a value below the critical speed of drop extraction in two-phase production wells, and as consequence liquid is accumulated in the tubing, increasing the pressure drop and reducing the flow rate within the tube. Simulations were made using air-water as working fluids over a vertical pipe of 4 meters long through a commercial package of CFD. Comparison between the simulation results and the experimental data available in the literature shows a good capability of homogeneous models to predict the flow characteristics for a given velocity range close to the critical gas velocity; over 100% of this parameter the model significantly overestimates the pressure drop.

    International Nuclear Information System (INIS)

    Miles, K.J.; Kalimullah.

    1985-01-01

    The current emphasis in LMFBR design is to develop reactor systems that contain as many features as possible to limit the severity of hypothetical accidents and provide the maximum time before corrective action is required while maintaining low capital costs. One feature is the possibility of fission-gas induced axial extrusion of the fuel within the intact cladding. The potential exists for this phenomenon to enable the reactor to withstand most accidents of the TOP variety, or at least provide an extended time for corrective action to be taken. Under transient conditions which produce a heating of the fuel above its nominal operating temperature, thermal expansion of the material axially produces a negative reactivity effect. This effect is presently considered in most accident analysis codes. The phenomenon of fission-gas induced axial extrusion has received renewed interest because of the consideration of metal alloys of uranium and plutonium for the fuel in some current reactor designs

    The early morning hyperglycemia of diabetic patients has been commonly referred to as the "dawn phenomenon". Recently the nocturnal surges of growth hormone (GH) have been suggested as an important factor in the pathogenesis of the dawn phenomenon. In order to reassess the role of the nocturnal GH secretion in the dawn phenomenon, seven C-peptide negative diabetic patients were studied during 48hr-feedback control using a closed-loop insulin infusion device (Biostator). They received oral sleeping medication only on the first night (control) and sleeping medication with anticholinergic agent (pirenzepine 75mg) on the second night, and blood glucose, insulin requirements, GH and cortisol concentrations during 0000hr and 0700hr were measured. The peak of sleep-induced GH secretions was markedly suppressed by pirenzepine in comparison with the control night (19.8 +/- 3.7 vs. 3.0 +/- 1.2ng/ml; p less than 0.05). Insulin requirements during 0500hr and 0700hr were suppressed significantly by pirenzepine (3.0 +/- 0.2 vs. 2.0 +/- 0.2U/2hr; p less than 0.05). Insulin infusion ratio, i.e. insulin requirements during 0500hr and 0700hr divided by those during 0000hr and 0200hr, was decreased by pirenzepine (2.2 +/- 0.3 vs. 1.5 +/- 0.2; p less than 0.05). There were no significant differences in blood glucose and cortisol concentrations whether or not the anticholinergic agent was given. In conclusion, these results have shown that an anticholinergic agent may be useful in the management of insulin-treated patients with marked dawn phenomenon.

    Highlights: • A low computational tool for heat transfer prediction on slug flows is presented. • The scooping phenomenon is modeled on a stationary approach. • The scooping phenomenon improved in 8% the heat transfer results. - Abstract: The heat transfer between the deep sea waters and the oil and gas mixtures flowing through production lines is a common situation in the petroleum industry. The optimum prediction of the liquid–gas flow parameters along those lines, when the intermittent flow pattern known as slug flow is dominant, has extreme importance in facilities' design. The mixture temperature drop caused by the colder sea waters, which can be regarded as an infinite medium with constant temperature, directly affects physical properties of the fluids such as the viscosity and specific mass. Gas expansion may also occur due to pressure and temperature gradients, thus changing the flow hydrodynamics. Finally, the temperature gradient affects the thermodynamic equilibrium between the phases, favoring wax deposition and thus increasing pressure drops or even blocking the production line. With those issues in mind, the present work proposes a stationary model to predict the mixture temperature distribution and the two-phase flow heat transfer coefficient based on the mass, momentum and energy conservation equations applied to different unit cell regions. The main contribution of the present work is the modeling of the thermal scooping phenomenon, i.e., the heat transfer between two adjacent unit cells due to the mass flux known as scooping. The model was implemented as a structured Fortran95 code with an upwind difference scheme. The results were compared to experimental data and presented good agreement. The analysis showed that the inclusion of the scooping phenomenon into the model resulted in an averaged 8% improvement in the temperature gradient calculation and heat transfer coefficient prediction for the flowing mixture.

    We theoretically investigate the unexpected occurrence of an extra emission peak that has been experimentally observed in off-resonant studies of cavity QED systems. Our results within the Markovian master equation approach successfully explain why the central peak arises, and how it reveals that the system is suffering a dynamical phase transition induced by the phonon-mediated coupling. Our findings are in qualitative agreement with previous reported experimental results, and the fundamental physics behind this quantum phenomenon is understood.

  9. Tidal wave phenomenon as a lever of tourist development in Greece-Halkis case

    Directory of Open Access Journals (Sweden)

    Stefanos, Karagiannis

    2006-01-01

    Full Text Available Tourist season in Halkis is nowadays limited to the three summer months offering a resort for weekend tourists (Athens-Halkis. Halkis is given the opportunity to improvise and illustrate its cultural and historical elements that constitute her uniqueness by establishing a local development programme that would include alternate tourism forms. This proposal regarding the tourist development of Halkis through tidal phenomena is primarily an alternative tourist development model. It differs from current development standards characterized by inequality, environmental and cultural degradation. This is based on the assumption that proposing an alternative tourism form in Halkis would lead to the initiation and exploitation of factors that are disregarded nowadays, that could ignite the tourist rebirth of this area. The creation of new employment positions and the amelioration of life conditions in this town could prevent the constant escape of the vital work-force to Athens and Piraeus. The success of the tourist development through the tidal phenomenon can be considered either a complete solution or an alterna-tive model. This may be unique from the tourist aspect, as the tidal phenomenon of Euripus could be the attraction pole, for a great number of people because this tourist forms (observation of a unique yet in-teresting natural phenomenon is contradictory to luxury. Simultaneously, the Mediterranean nutrition could be co-depicted, by offering the opportunity to the tourist to become more intimate with local prod-ucts. This would help people understand the importance of Euripus tidal phenomenon for the tourist development of Halkis

    Mathers, S E; Kempster, P A; Swash, M; Lees, A J

    1988-12-01

    Anismus, or constipation due to functional obstruction at the pelvic outlet by paradoxical contraction of the striated sphincter muscles during defaecation straining, is described in ten constipated patients and four patients with Parkinson's disease and constipation. The dysfunctional pattern of muscle recruitment resembled that characteristic of dystonia elsewhere in the body and was indistinguishable in patients with idiopathic anismus and those with extrapyramidal motor disturbance due to Parkinson's disease. These findings suggest that anismus may be a focal dystonic phenomenon.

    Seoighe, Deirdre M

    2012-02-01

    Wound management in burns is a potentially complex issue. Salivary constituents have been shown experimentally to be of benefit in the treatment of thermal injuries. In our clinical experience we have encountered patients who have saliva directly applied to the burn wound prior to presenting to the national burns service. The practice is known as "Licking". We report two cases to illustrate the presentations we have encountered. We believe that these illustrate an isolated phenomenon unique to the Republic of Ireland.

  2. Spontaneous burp phenomenon: analysis of experimental data and approach to theoretical interpretation

    International Nuclear Information System (INIS)

    Shabalin, E.

    2004-01-01

    Cases of spontaneous release of energy (''burp'') were observed numerously in solid methane, water ice and other hydrogeneous compounds irradiated in fast neutron fields with absorbed dose 2-10 MGy. Nature of this phenomenon is that accumulation of radicals and thermal instability of a sample under due concentration of radicals culminate to autocatalytic reaction of their recombination. The most odious feature of this phenomenon is that irradiation time, before a burp occurs, varies significantly even in identical irradiation condition. Respectively, amount of released energy varies as well. For example, in URAM-2 experiments with water ice, irradiation time before appearance of spontaneous burp varied from 5 hours to 11 hours for equal samples and up to 20 hours for the smallest sample. Another feature of the phenomenon is that regularities for occurrence of spontaneous release of energy (that is, dependence on temperature, size of sample, absorbed dose) can't be extracted explicitly from experimental data, if applying known relations for critical concentration of radicals, namely: Semenov's and Frank-Kamenetski's conditions of thermal instability of a sample, Jackson's relation for chain process of recombination of uniformly distributed radicals, critical condition based on accounting for acceleration of a process of recombination in the regions of micro-cracks, and, finally, critical condition for irregular distribution of radicals proposed by the author of this article. Not one of these theories predicts casual character of a burp on macro-scale basis. So that, notwithstanding fair amount of experimental data on spontaneous burps, it is still impossible to derive well-balanced theory of this phenomenon. One attempt to understand a reason for the strange behavior of spontaneous burping is a probabilistic, cluster model of spontaneous release of energy, developed in the chapter 4 of this paper. Spontaneous burps observed during URAM-2 project and in solid methane

    There has been a crescent interest in the scientific community in the study of natural circulation phenomenon. New generation of compact nuclear reactors uses the natural circulation of the fluid as a system of cooling and of residual heat removal in case of accident or shutdown. The objective of this paper is to compare the flow patterns of experimental data and numerical simulation for the natural circulation phenomenon in two-phase flow regime. An experimental circuit built with glass tubes is used for the experiments. Thus, it allows the thermal hydraulic phenomena visualization. There is an electric heater as the heat source, a heat exchanger as the heat sink and an expansion tank to accommodate fluid density excursions. The circuit instrumentation consists of thermocouples and pressure meters to better keep track of the flow and heat transfer phenomena. Data acquisition is performed through a computer interface developed with LABVIEW. The characteristic of the regime is identified using photography techniques. Numerical modeling and simulation is done with the thermal hydraulic code RELAP5, which is widely used for this purpose. This numerical simulation is capable to reproduce some of the flow regimes which are present in the circuit for the natural circulation phenomenon. Comparison between experimental and numerical simulation is presented in this work. (author)

  4. Mobbing in the practice of Polish enterprises – recognizability of the phenomenon

    Full Text Available Systematic, permanent, time-staggered hostile behavior towards an employee are just some of the features of the phenomenon known as mobbing. Such behaviors lead to mental and often physical destruction. We meet with them every day because it has been accompanied by hostility since the beginning of its existence, as an emotion, and the need to acquire and overcome. The motives of applying such behaviors depend not only on the internal characteristics of the human being that enable him to meet his needs. In a professional environment, it is the lack of appropriate rules of mutual coexistence, consent to such behavior by concealing their occurrence as well as deliberate actions. The article presents the phenomenon of mobbing in the practice of Polish enterprises. It indicates what is mobbing and what behaviors are legally recognized as mobbing. It presents the size of this phenomenon in Poland, its causes as well as the effects of using mobbing for an employee and an entrepreneur. In this article, the author is based on the literature available in this area, compares the research conducted by CBOS in 2002 and 2014, as well as the research by HR Sedlak & Sedlak, from 2015, and tries to complement this multidimensional problem with its perception by the serial employees.

  5. Dip Phenomenon in High-Curved Turbulent Flows and Application of Entropy Theory

    Directory of Open Access Journals (Sweden)

    Donatella Termini

    2018-03-01

    Full Text Available The estimation of velocity profile in turbulent open channels is a difficult task due to the significant effects of the secondary flow. The present paper investigates the mechanism of the velocity-dip phenomenon, whereby the location of the maximum velocity appears to be below the free surface. Previous studies conducted in straight channels relate the mechanism of the velocity-dip phenomenon to secondary flow induced by anisotropy of turbulence. This work focuses on high-curved channels where the secondary motion, which is also induced by the channel’s curvature, evolves along the bend. The width-to-depth ratio, B/h, is one of the most important parameters that are affecting the secondary motion entity. In particular, the present study aims to investigate the evolution of the velocity-dip along the bend for two values of the width-to-depth ratio and the applicability of the entropic model for the dip-phenomenon estimation. The results show that the velocity-dip is more accentuated for low values of the width-to-depth ratio, where the secondary motion plays a fundamental role in the distribution of the downstream flow velocity, although the velocity-dip is also present when the aspect ratio is higher than 10. Furthermore, the velocity profiles that were estimated by applying the entropic model are in good agreement with the measured ones, especially for B/h < 10.

  6. UV inactivation of enzymes in supramolecular complexes of biological membranes. The phenomenon of photochemical allotropy

    The photosensitivity of erythrocyte acetylcholinesterase (AChE) is different in its free and membrane-bound states. The modification of the structure of membraneous lipids by phospholipases A 2 , C and D or by cholesterol depletion is accompanied by a change in AChE photosensitivity. UV light was demonstrated to induce cooperative structural transitions in the erythrocyte membrane. This follows from the data obtained by circular dichroism and solubilization in detergents. In contrast to free AChE, UV light acts on the membraneous enzyme as a mixed inhibitor (simultaneous change in Vsub(max) and Ksub(m)). The anomalous behaviour of membrane-bound enzyme, termed the phenomenon of photochemical allotropy, is associated with a modification of the structure within the microenvironment of the residual AChE. The phenomenon depends on membrane integrity, and disappears after treatment of erythrocyte ghosts with ultrasound, trypsin, phospholipases and neuraminidase and remains unchanged in cholesterol-depleted membranes. The nature and localization of events responsible for this phenomenon are discussed. (author)

    Full Text Available The harmfulness of the job burnout phenomenon of Chinese university counsellors cannot be neglected. How to relieve counsellors’ job burnout effectively by improving their involvement in work is an important research field. Firstly, to start from three aspects of social roots, organizational roots and personal factors, the writer conducts a preliminary interpretation about the key factors leading to the job burnout of university counsellors which include the workload, role conflict, role ambiguity, a sense of fairness, job characteristics, personality factor, etc. Then, to start from the roots as well as the connotation of job burnout, the writer elaborates that job burnout is a state of body, emotional and spirit exhaustion, especially the wastage and continuous fatigue of body, a sense of hopelessness and desperation, negative self-concept and a negative attitude towards life and work. Finally, from three aspects of mind emancipation, firm faith and clear roles in profession, solution, learning strengthening and self-efficacy enhancing, the writer proposes a countermeasure to solve the job burnout phenomenon of university counsellors, and compares the effect of dealing with job burnout phenomenon according to the data before and after one year practice.

  8. ["Placebo effect", from personal convictions to collective representations: A psychosocial reading of a pharmacodynamic phenomenon].

    2015-11-01

    After starting with a brief historical account of the placebo effect organized around the elaboration of clinical trials and around sham therapy as a method, we will offer a psychosocial point of view on the placebo phenomenon. The placebo effect is at the heart of medicine and particularly of therapeutic trials from theoretical research on a drug to its acceptance and its use in every-day clinical practice. The placebo effect intermingles biology, relationships and the context of therapeutic interactions. This type of phenomenon originates as much from biology as from human psychology. Our article puts more precisely into question the part that psychology has in the placebo phenomenon and suggests a chart to address it. This chart refers both to the pharmacodynamic effect given to drugs in a subjective way, and to the collective representations and social interactions depending on them. What can we say about the psychosociological dimensions of the placebo effect? How is it possible to organize the scope of these dimensions to base systematic studies on them in the field of clinical trials? We try to give elements of response to these questions by suggesting the study of the placebo effect as an original field of study by necessarily mobilizing both health sciences and the human and social sciences.

  9. The Role of Photographs and Films in Kettlewell's Popularizations of the Phenomenon of Industrial Melanism

    Science.gov (United States)

    Wÿss Rudge, David

    H.B.D. Kettlewell's investigations on the phenomenon of industrial melanism are generally referred to in textbooks and other popularizations of science as the classic demonstration of natural selection (Majerus 1989). A central question for historians of this episode is accounting for why public perceptions of the importance of Kettlewell's work have diverged from those of researchers who actually work on the phenomenon. In a recent paper published in Biology and Philosophy, Joel Hagen draws attention to the role Kettlewell and his colleagues played in idealizing his investigations as an example of controlled experimentation in their several retrospective popular accounts. The present essay discusses the important role photographic and film depictions of differential bird predation played in Kettlewell's popularizations. This analysis supports Hagen's contentions that Kettlewell deftly and strategically used these visual representations to command assent to his interpretation of the phenomenon and shore up claims about the scientific legitimacy and importance of his work. It nevertheless disputes that these images were intended to portray Kettlewell's experiments as an example of controlled experimentation. In a concluding section, the essay draws several morals from this analysis regarding the use of popularized articles and visual images to teach science.

    2016-12-01

    Full Text Available It is obvious that the migration wave from the Orient is a challenge for Europe and especially for the Catholic and Protestant countries. Its geopolitical, economic, social, cultural, theological and spiritual significance have hardly any competition in the old evolution of the world, the secularisation from the 17th century or the globalisation from the 21st century. From this perspective, it is necessary to study carefully the migration phenomenon in its assembly, trying to present an integrated and multi-criteria diagnosis, especially due to the fact that the migration phenomenon brings closer to each of us the huge and extremely difficult problem of Muslim radicalisation, together with its cohort of terrorist manifestations endangering the most important human right: the right to life. Our study is intentionally intended to evaluate and commensurate, using Orthodox theological criteria, the impact of the actual migration phenomenon, the life of the Muslim community – umma, related to the Christian community from the multicultural European society. We start from the opposed manner the two sides relate to society, understand freedom and the dialogue between religions.

    In Raynauds phenomenon, the authors measured finger blood flow after ice water exposure by analyzing the time activity curve of radionuclide angiography on both hands. The results were as follows: 1) The digital blood flow did not decrease after ice water exposure in normal subjects. 2) In the patients with Raynauds phenomenon, there were two groups: the one had decreased digital blood flow after cold exposure, and the other had paradoxically increased digital blood flow after cold exposure. 3) There was no difference in the digital blood flow of hand in room temperature between the normal and the patients with reduced digital blood flow after cold exposure, but the digital blood flow of the hand in room temperature was markedly reduced in the patients with paradoxically increased flow after cold exposure. 4) In the static image the difference was not significant in comparison with the dynamic study, because it represents pooling of the blood in the vein rather than flow. 5) After the treatment with nifedipine, the digital blood flow increased. In conclusion, the radionuclide angiography was useful in measuring the digital blood flow in Raynauds phenomenon, and further studies with various drugs is expected.

    The Enright phenomenon describes the distortion in speed perception experienced by an observer looking sideways from a moving vehicle when viewing with interocular differences in retinal image brightness, usually induced by neutral density filters. We investigated whether the Enright phenomenon could be induced with monocular pupil dilation using tropicamide. We tested 17 visually normal young adults on a closed road driving circuit. Participants were asked to travel at Goal Speeds of 40km/h and 60km/h while looking sideways from the vehicle with: (i) both eyes with undilated pupils; (ii) both eyes with dilated pupils; (iii) with the leading eye only dilated; and (iv) the trailing eye only dilated. For each condition we recorded actual driving speed. With the pupil of the leading eye dilated participants drove significantly faster (by an average of 3.8km/h) than with both eyes dilated (p=0.02); with the trailing eye dilated participants drove significantly slower (by an average of 3.2km/h) than with both eyes dilated (p<0.001). The speed, with the leading eye dilated, was faster by an average of 7km/h than with the trailing eye dilated (p<0.001). There was no significant difference between driving speeds when viewing with both eyes either dilated or undilated (p=0.322). Our results are the first to show a measurable change in driving behaviour following monocular pupil dilation and support predictions based on the Enright phenomenon.

    Bone scintigraphy (BS) lacks sensitivity for detecting very early skeletal metastases (SM) in prostate cancer (PC) and is often limited by poor specificity. Also scintigraphic flare of SM can occur following effective treatment and mislead an early response assessment. We hypothesised that a flare reaction might amplify the signal from subclinical SM, increasing the sensitivity of BS and that the phenomenon may be specific for metastases. We conducted a prospective study to determine the frequency of the flare phenomenon in patients with metastatic PC starting hormone therapy and to explore its utility in patients with negative staging scans but considered at high risk of SM and in those with equivocal baseline BS abnormalities. Ninety-nine patients commencing first-line hormone therapy had repeat BS at 6 weeks to score a flare reaction. Of 22 patients with unequivocal SM on the baseline scan, a flare occurred in 9 (41%). Of 36 high-risk localised prostate cancer patients with normal BS pre-treatment, the scan became positive for metastases at 6 weeks in 4 (11%). Of 41 patients with pre-treatment scintigraphic abnormalities of uncertain aetiology, a flare occurred in 8 cases (20%). All eight were confirmed to have SM by follow-up and imaging. Of the 33 remaining patients without a flare, 2 developed SM at 14 months and the remainder did not develop SM in a median follow-up period of 36 months. The flare phenomenon following initial hormone therapy can be used to improve both sensitivity and specificity of BS in PC. (orig.)

    Liu, Xiaojing; Ren, Shuo; Cheng, Xu

    2017-01-01

    Highlights: • Experiment data of Krauss is used to validate the feasibility of CFD simulation method. • CFD simulation is performed to simulate the large scale impulsion phenomenon for tight-lattice bundle. • A mixing model to simulate the large scale impulsion phenomenon is proposed based on CFD result fitting. • The new developed mixing model has been added in the subchannel code. - Abstract: Tight-lattice is widely adopted in the innovative reactor fuel bundles design since it can increase the conversion ratio and improve the heat transfer between fuel bundles and coolant. It has been noticed that a large scale impulsion of cross-velocity exists in the gap region, which plays an important role on the transverse mixing flow and heat transfer. Although many experiments and numerical simulation have been carried out to study the impulsion of velocity, a model to describe the wave length, amplitude and frequency of mixing coefficient is still missing. This research work takes advantage of the CFD method to simulate the experiment of Krauss and to compare experiment data and simulation result in order to demonstrate the feasibility of simulation method and turbulence model. Then, based on this verified method and model, several simulations are performed with different Reynolds number and different Pitch-to-Diameter ratio. By fitting the CFD results achieved, a mixing model to simulate the large scale impulsion phenomenon is proposed and adopted in the current subchannel code. The new mixing model is applied to some fuel assembly analysis by subchannel calculation, it can be noticed that the new developed mixing model can reduce the hot channel factor and contribute to a uniform distribution of outlet temperature.

    The formation of a supercooled liquid region and devitrification behaviour of metallic glasses on heating are discussed in relation with the glass-transition phenomenon observed using differential scanning and isothermal calorimetries as well as X-ray diffraction and transmission electron microscopy (TEM). One of the most clear sequences of the glassy ↔ supercooled liquid phase transition is the change of the devitrification behaviour and the kinetics of the devitrification reaction in Al-based and some other alloys after the transition from the glassy to the supercooled liquid state. The significant variation in the devitrification behaviour and thermodynamic parameters indicate the difference between the glassy and the supercooled liquid phases

    The study of the discharge of active or self-driven matter in narrow passages has become of the growing interest in a variety of fields. The question has particularly important practical applications for the safety of pedestrian human flows notably in emergency scenarios. It has been suggested predominantly through simulation in some theoretical studies as well as through few experimentations that under certain circumstances, an elevated vigour to escape may exacerbate the outflow and cause further delay although the experimental evidence is rather mixed. The dimensions of this complex phenomenon known as the "faster-is slower" effect are of crucial importance to be understood owing to its potential practical implications for the emergency management. The contextual requirements of observing this phenomenon are yet to be identified. It is not clear whether a "do not speed up" policy is universally beneficial and advisable in an evacuation scenario. Here for the first time we experimentally examine this phenomenon in relation to the pedestrian flows at merging sections as a common geometric feature of crowd egress. Various merging angles and three different speed regimes were examined in high-density laboratory experiments. The measurements of flow interruptions and egress efficiency all indicated that the pedestrians were discharged faster when moving at elevated speed levels. We also observed clear dependencies between the discharge rate and the physical layout of the merging with certain designs clearly outperforming others. But regardless of the design, we observed faster throughput and greater avalanche sizes when we instructed pedestrians to run. Our results give the suggestion that observation of the faster-is-slower effect may necessitate certain critical conditions including passages being overly narrow relative to the size of participles (pedestrians) to create long-lasting blockages. The faster-is-slower assumption may not be universal and there may be

    The main objective of this research is to develop a three-group neutron Albedo algorithm considering the up-scattering of neutrons in order to analyse the diffusion phenomenon in nonmultiplying media. The neutron Albedo method is an analytical method that does not try to solve describing explicit equations for the neutron fluxes. Thus the neutron Albedo methodology is very different from the conventional methodology, as the neutron diffusion theory model. Graphite is analyzed as a model case. One major application is in the determination of the nonleakage probabilities with more understandable results in physical terms than conventional radiation transport method calculations. (author)

    Dissociative symptoms and disorders have been reported in many different cultures. If pathological dissociation is naturally occurring and related to adverse experiences, such phenomena should have been witnessed and portrayed before the modern age. To investigate whether this is the case, the author made use of the rich ancient Chinese medicine literature and looked for descriptions of pathological dissociation in medical documents written by ancient Chinese medical practitioners. In this paper, the author presents six cases selected from the ancient Chinese medicine literature. The phenomenon of pathological dissociation is observed in these cases. This is the first report of case descriptions of pathological dissociation documented in Chinese cultures before 1900.

    Full Text Available David Rapoport’s Wave theory of terrorism is one of the most oftencited theories in the literature on terrorist violence. Rapoport is praised for having provided researchers with a universal instrument which allows them to explain the origin and transformation of various historical types of terrorism by applying to them the concept of global waves of terrorist violence driven by universal political impulses. This article, testing the Wave theory against the recent phenomenon of homegrown jihadism in Europe, uncovers this theory’s fundamental weaknesses and questions its real academic and practical value.

However, repeated injections of PEGylated nanocarriers induces the accelerated blood clearance (ABC phenomenon, prevents long circulation, and can cause adverse effects owing to alterations in the biodistribution of the drug. Although the nature of the ABC phenomenon that is induced by repeated injections of PEGylated nanocarriers has already been studied in detail, there are few reports on the immune response elicited by the cross-administration of PEGylated nanocarriers. In this study, we investigated the ABC phenomenon induced by the intravenous cross-administration of various PEGylated nanocarriers, including PEGylated liposomes (PL, PEG micelles (PM, PEGylated solid lipid nanoparticles (PSLN, and PEGylated emulsions (PE, in beagle dogs. The results indicated that the magnitude of the immune response elicited by the cross-administration was in the following order (from the strongest to the weakest: PL, PE, PSLN, PM. It is specifically PEG in the brush structure that elicits a significant immune response, in both the induction phase and the effectuation phase. Furthermore, the present study suggests that there is a considerable difference between the effect of repeated injections and

    Six North to South passes of AUREOL/ARCAD 3 satellite through the equatorial electron density depletion at variable altitude between 400 and 550 km, at night, during a two weeks period, exhibit a similar feature in plasma density irregularities which are thought to be associated with spread F phenomenon. The irregularities are found to be quasi-sinusoidal with a scale size of about 2 km along the satellite trajectory and occur only on the Northern edge of the equatorial electron density depletion. This implies a violation of the generally believed principle of conjugate mapping for those wavelengths. These observations are analysed and discussed in terms of different known generation mechanisms

    A mathematical model for the ‘hit’ phenomenon in entertainment within a society is presented as a stochastic process of human dynamics interactions. The model uses only the advertisement budget time distribution as an input, and word-of-mouth (WOM), represented by posts on social network systems, is used as data to make a comparison with the calculated results. The unit of time is days. The WOM distribution in time is found to be very close to the revenue distribution in time. Calculations for the Japanese motion picture market based on the mathematical model agree well with the actual revenue distribution in time.

    We introduce an analytical approach to describe the multi-state lasing phenomenon in quantum dot lasers. We show that the key parameter is the hole-to-electron capture rate ratio. If it is lower than a certain critical value, the complete quenching of ground-state lasing takes place at high injection levels. At higher values of the ratio, the model predicts saturation of the ground-state power. This explains the diversity of experimental results and their contradiction to the conventional rate equation model. Recently found enhancement of ground-state lasing in p-doped samples and temperature dependence of the ground-state power are also discussed.

    Numerical simulations of the Lorenzian water wheel have been used to investigate the influence of stochastic noise on the lifetime of chaotic transients. Whereas in one region of parameter space no noise dependency could be detected, a shortening of the lifetimes by more than four decades was found in another region. This large effect was produced by a significant modification of the attraction basin of a quasistable stationary state rather than by affecting the chaotic orbits before the chaos-order transition occurred. This novel phenomenon of noise-induced chaos-order transitions is not related to stochastic resonance or other noise-induced effects. (author) 2 figs., 5 refs.

    2008-01-01

    We study the radiative corrections of QED 3 from the dual point of view and show that this process is the exact dual to the Julia-Toulouse mechanism introduced by Quevedo and Trugenberger [F. Quevedo, C.A. Trugenberger, Nucl. Phys. B 501 (1997) 143] some years ago. We discuss the physics behind this mechanism that involves condensation of topological defects. It is shown that the dual Stuckelberg mechanism is responsible for the 'rank-jump' phenomenon that transforms the scalar field (dual to Maxwell in this dimensionality) into the vectorial self-dual field. This phenomenon is studied using the ideas of noncommutative fields theory that examines possible deformations of the canonical structure of some well-known models in (2+1)D. A deformation is constructed linking the massless scalar field theory with the self-dual theory. This is the exact dual of the known deformation connecting the Maxwell theory with the Maxwell-Chern-Simons theory. Duality, radiative corrections, the Julia-Toulouse mechanism and canonical deformations are then used to establish a web of relations between the mentioned theories and to propose a physical picture of the deformation procedure adopted

    Cocaine abuse remains a significant worldwide health problem. Patients with cardiovascular toxicity from cocaine abuse frequently present to the emergency department for treatment. These patients may be tachycardic, hypertensive, agitated, and have chest pain. Several pharmacological options exist for treatment of cocaine-induced cardiovascular toxicity. For the past 3 decades, the phenomenon of unopposed α-stimulation after β-blocker use in cocaine-positive patients has been cited as an absolute contraindication, despite limited and inconsistent clinical evidence. In this review, the authors of the original studies, case reports, and systematic review in which unopposed α-stimulation was believed to be a factor investigate the pathophysiology, pharmacology, and published evidence behind the unopposed α-stimulation phenomenon. We also investigate other potential explanations for unopposed α-stimulation, including the unique and deleterious pharmacologic properties of cocaine in the absence of β-blockers. The safety and efficacy of the mixed β-/α-blockers labetalol and carvedilol are also discussed in relation to unopposed α-stimulation.

  10. Studying friction while playing the violin: exploring the stick-slip phenomenon.

    Science.gov (United States)

    Casado, Santiago

    2017-01-01

    Controlling the stick-slip friction phenomenon is of major importance for many familiar situations. This effect originates from the periodic rupture of junctions created between two rubbing surfaces due to the increasing shear stress at the interface. It is ultimately responsible for the behavior of many braking systems, earthquakes, and unpleasant squeaky sounds caused by the scratching of two surfaces. In the case of a musical bow-stringed instrument, stick-slip is controlled in order to provide well-tuned notes at different intensities. A trained ear is able to distinguish slight sound variations caused by small friction differences. Hence, a violin can be regarded as a perfect benchmark to explore the stick-slip effect at the mesoscale. Two violin bow hairs were studied, a natural horse tail used in a professional philharmonic orchestra, and a synthetic one used with a violin for beginners. Atomic force microscopy characterization revealed clear differences when comparing the surfaces of both bow hairs, suggesting that a structure having peaks and a roughness similar to that of the string to which both bow hairs rubbed permits a better control of the stick-slip phenomenon.

  11. On the Force Drop Off Phenomenon in Shaker Testing in Experimental Modal Analysis

    Paulo Sergio Varoto

    2002-01-01

    Full Text Available The Electrodynamic Vibration Exciter (shakers has been one of the most employed excitation sources in modal tests. The shaker is an electromechanical device that provides a mechanical motion due to the input signal sent to its coil. Despite being widely used, it is well known that the shaker interacts with the structure under test. In particular, when the structure passes through a given resonance, the force delivered by the shaker abruptly decreases, causing the so called drop off phenomenon. This paper aims to study this force drop off phenomenon in the single shaker modal testing. Analytical models are developed to help in understanding the physical principles involved in the interaction between the shaker and the structure under test. Experimental analyses are performed using different shakers as well as excitation signals, in order to evaluate the effects of the input signal, as well as the power amplifier operational modes, on the structure dynamics. Preliminary tests revealed that significant distortions might occur during vibration tests using shakers and these distortions significantly affect the determination of the structure response.

  12. Design and jump phenomenon analysis of an eccentric ring energy harvester

    This paper presents the development of a wheel-mounted eccentric ring energy harvester that is driven by centripetal and gravitational forces during wheel rotation. The natural frequency of the eccentric ring matches the wheel rotation frequency at any car speed because its character length is designed equal to the wheel radius. Consequently, the eccentric ring oscillates with a relatively large swing angle at the wheel speed to generate high levels of power. The nonlinear dynamic behavior of the eccentric ring is investigated to ensure that the proposed design produces steady swing angles, especially at high wheel speeds. Herein, the jump phenomenon of the dynamic motion of the eccentric ring is analyzed by using the Duffing equation and the linearization process. The discriminant value obtained from the analysis confirms that no jump phenomenon occurs at all wheel speeds if the eccentric ring is properly designed. In the experiment, the eccentric ring is integrated with magnets and a coil set to generate 318–442 μW at constant wheel speeds between 300 and 500 rpm. This shows that the proposed device is a potential power source for low-power wheel-mounted electronics, such as pressure sensors, accelerometers, and thermometers. (paper)

    Full Text Available Introduction: In Colombia, where each person would have the right to access 50.000 m3 of water per year, a 50% of population does not have access to potable water, 10 millions of Colombians do not own an aqueduct system and at least 800 municipal headers are about to disappear. In this article are presented the political factors that take over the water resources in state sovereignty terms; which could canalize the appearance of water stress phenomenon in the country, which is reality to Mexico and Peru. Materials and method: Reection from the literature review was realized through recompilation of 30 documents in Universidad Nacional of Colombia database. 22 articles were selected. Results: Water stress is the progressive deterioration of water resources of a country in terms of quality and quantity. This phenomenon begins to appear in Colombia as a social problem due to excessive use of water by the agricultural / livestock industries, and oil, gas and mining multinational companies, in which the state does not applies any control. Conclusions: The competent resource governance and protection are been forced by international politics shown especially in developing countries, which neglect their vulnerable communities. Being sovereignty an elemental characteristic of each state, it is governmental duty to regulate water resources as fundamental source of well-being and maintenance of its population.

    The influence of sedimentation phenomena on the operational parameters of the hydropower reservoirs built on several Romanian rivers was assessed. A cascade of eight reservoirs on the Olt river, with initial volumes of 20-50 M m 3 , lost about 30% of the conservation capacity and about 3-7% of head as well. Smaller reservoirs, with volumes of 2-10 M m 3 , lost 60-85% of their capacity. Dredging operations had to be done, thus, increasing the initial costs by 20%. The acquired experience revealed that the evolution in time of the reservoir capacity over the operation period should be as accurately as possible taken into account in the designing stage. The operation conditions and designing criterions for small and medium hydropower reservoir have to be reassessed also from the environmental and efficiency points of view. The content of the paper is the following: 1. Sedimentation knowledge and planning concepts for inland rivers; 2. Implications of the sedimentation phenomenon; 3. Forecast of the sedimentation phenomenon; 4. Retrospective and perspective; 5. Conclusions. (authors)

    2013-01-01

    In this paper He-discharge (plasma jet/bullet) in atmospheric pressure air and its progression phenomenon has been studied experimentally using ICCD camera, optical emission spectroscopy (OES) and calibrated dielectric probe measurements. The repetitive nanosecond pulse has applied to a plasma pencil to generate discharge in the helium gas channel. The discharge propagation speed was measured from the ICCD images. The axial electric field distribution in the plasma jet is inferred from the optical emission spectroscopic data and from the probe measurement. The correlation between the jet velocities, jet length with the pulse duration is established. It shows that the plasma jet is not isolated from the input voltage along its propagation path. The discharge propagation speed, the electron density and the local and average electric field distribution along the plasma jet axis predicted from the experimental results are in good agreement with the data predicted by numerical simulation of the streamer propagation presented in different literatures. The ionization phenomenon of the discharge predicts the key ionization parameters, such as speed, peak electric field in the front, and electron density. The maximum local electric field measured by OES is 95 kV/cm at 1.3 cm of the jet axis, and average EF measured by probe is 24 kV/cm at the same place of the jet. The average and local electron density estimated are in the order of 10 11 cm -3 and it reaches to the maximum of 10 12 cm -3 .

    Body Worlds, the international plastination phenomenon, has proved immensely popular with audiences worldwide. Never before has the human body been exposed to public gaze in such an accessible and intriguing manner. Dissected body parts feature alongside whole-body plastinates with their life-like poses ranging from those with Renaissance motifs to others with highly contemporary themes. However, the exhibitions and their creator, Gunther von Hagens, have astounded many, including anatomists, some of whom find the unconventional display of human bodies unethical and offensive. The voyeuristic nature of Body Worlds and the uneasy balance between entertainment and education have proved problematic for anatomists. Von Hagens himself is a polarizing figure, pursuing his dream of "democratizing anatomy" with little regard for the conventions of academia. While valid ethical objections can be raised against some aspects of the exhibitions, we argue that wholesale rejection of them is unwarranted. In arriving at this conclusion we assess the ethical and educational issues involved. We divide the whole-body plastinates into four categories, ranging from those illustrating structural and functional relationships to those with artistic and humanistic aspirations rather than anatomical ones. We conclude that anatomists need to face up to the opportunities and challenges posed by the Body Worlds phenomenon, utilizing what is being presented to the general public and adapting this in teaching and research.

  18. The Labor Market from Romania from the Perspective of Migration Phenomenon

    Full Text Available Population migration is a real phenomenon that has amplified over the last two decades and will continue to grow as major disparities between regions develop. There are many reasons that generate the trend of population movement. The reasons/ motive that are frequently invoked are the conflictual situation related issues that primarily affect individual security, political and social fragility, economic instability with effects in all areas of activity, degradation of living conditions, and the high risk of terrorism in certain areas. The population migration is not necessarily a bad thing if we are looking through the perspective of chances it offers to both people and the economy as a whole, being also an important factor for the growth of national and international trade. But, the lack of some decisions to control this phenomenon creates long-term imbalances. These imbalances are already extremely visible in the Romanian labor market. Numerous work field have a major staff lack and are need of solutions for doing business under normal conditions. Therefore, the present paper aims at highlighting the main features of the labor market, the country's risks, as well as identifying viable solutions for reducing economic and social imbalances.

    Reservoirs are fundamental human-built infrastructures that collect, store, and deliver fresh surface water in a timely manner for many purposes. Efficient reservoir operation requires policy makers and operators to understand how reservoir inflows are changing under different hydrological and climatic conditions to enable forecast-informed operations. Over the last decade, the uses of Artificial Intelligence and Data Mining [AI & DM] techniques in assisting reservoir streamflow subseasonal to seasonal forecasts have been increasing. In this study, Random Forest [RF), Artificial Neural Network (ANN), and Support Vector Regression (SVR) are employed and compared with respect to their capabilities for predicting 1 month-ahead reservoir inflows for two headwater reservoirs in USA and China. Both current and lagged hydrological information and 17 known climate phenomenon indices, i.e., PDO and ENSO, etc., are selected as predictors for simulating reservoir inflows. Results show (1) three methods are capable of providing monthly reservoir inflows with satisfactory statistics; (2) the results obtained by Random Forest have the best statistical performances compared with the other two methods; (3) another advantage of Random Forest algorithm is its capability of interpreting raw model inputs; (4) climate phenomenon indices are useful in assisting monthly or seasonal forecasts of reservoir inflow; and (5) different climate conditions are autocorrelated with up to several months, and the climatic information and their lags are cross correlated with local hydrological conditions in our case studies.

  20. Involvement of Multiple Gene-Silencing Pathways in a Paramutation-like Phenomenon in Arabidopsis

    Full Text Available Paramutation is an epigenetic phenomenon that has been observed in a number of multicellular organisms. The epigenetically silenced state of paramutated alleles is not only meiotically stable but also “infectious” to active homologous alleles. The molecular mechanism of paramutation remains unclear, but components involved in RNA-directed DNA methylation (RdDM are required. Here, we report a multi-copy pRD29A-LUC transgene in Arabidopsis thaliana that behaves like a paramutation locus. The silent state of LUC is induced by mutations in the DNA glycosylase gene ROS1. The silent alleles of LUC are not only meiotically stable but also able to transform active LUC alleles into silent ones, in the absence of ros1 mutations. Maintaining silencing at the LUC gene requires action of multiple pathways besides RdDM. Our study identified specific factors that are involved in the paramutation-like phenomenon and established a model system for the study of paramutation in Arabidopsis.

    Full Text Available There a number of factors effecting consumers' purchase behavior. It is believed that celebrities can effect selling positively by transferring their popular image to the endorsed product. But, it is heard lots about excommunicate behaviors in the sport world today. Disclosure of the recent doping affairs relating to Lance Armstrong's seven wins in Tour De France is just one among many spectacular and also negative cases. The main aim of the present paper was to explore the effect of doping phenomenon on sport marketing. Depth interviews data were analyzed in three phases: open coding, axial coding, and selective coding. 297 open codes were achieved by 18 interviews. Grouping axial codes in each case and comparing, all gained codes can be divided in five groups: brand image (athlete and endorsed product brands images, moral reasoning (moral coupling, moral decoupling, and moral rationalization, consumer behavioral consequences (word of mouth, purchasing intention, and brand loyalty, attitude change (attitudes change toward athlete and brand, and moral emotions (moral evaluation, contempt, anger, disgust, and sympathy. The proposed qualitative model for the effect of doping phenomenon on sport marketing in Iran illustrated that moral emotions and product brand image affected by the doped athlete brand image and it resulted in attitudes change toward endorser athlete and endorsed brand and negative consumer behavioral consequences, however, moral reasoning strategies emerged by cognitive dissonance might protect consumers behavior from negative effects.

  2. The Phenomenon of Ukrainian Poverty in the Context of Threats to National Security

    Full Text Available Poverty is one of the unresolved problems among the socio-economic components in Ukraine. According to recent researches, the majority of the population of our country is beyond the limit of poverty. Experts from both Ukraine and the international organizations, including the UN, have different estimates of extent of poverty in Ukraine, citing different methods of calculation. However, whatever estimates be given to this social phenomenon, all experts agree on one thing: poverty in Ukraine is aggravated and covers the wider population of the country. The phenomenon of Ukrainian poverty is that for more than a quarter of a century inequality in the income of the population is growing, the price of labor is falling, and, paradoxically, the Government contributes to the growth of poverty by its regulation and deregulation of the economy, financial and social spheres. Therefore, the greatest threat to conducting reforms, ensuring the economic growth, to the entire national economy today, is the exorbitant poverty, which not only provides for the increase in labor migration, but leads to the total emigration of skilled workers, who are highly valued by employers of the near and far abroad countries. And yet, despite the significant economic potential, available resources, Ukraine remains one of the poorest countries in Europe.

    Delayed conduction along one optic nerve can result in an incorrect appreciation of moving objects. The temporal mismatch between the two different pathways results in altered perception of the vector of a moving target and is known as 'the Pulfrich phenomenon'. This is a well-recognised handicap in patients with multiple sclerosis, but has not previously been reported as a consequence of injury. All 187 patients who presented during 1991 with reduced visual acuity as a result of midfacial injuries were examined with a pendulum. Six had the defect and five of these had symptoms. In each case the patients were disturbed by car travel, because they perceived oncoming traffic moving in a hyperbolic curve towards them. These patients have been examined in detail and given a tinted lens for the normal eye to eliminate the illusion by delaying the input from the normal side to equal that on the damaged side. We recommend that this phenomenon is sought in all patients with mid-facial injuries or with later evidence of mild traumatic optic neuropathy, particularly if they are disturbed by car travel.

    Full Text Available A lot of controversies appear regarding temporal lobe epilepsy to bridge the gap between religion and neuroscience. TLE was described in literature in 1869 by Russian writer Dostoievski (who suffered from epilepsy, in his work ”The Idiot”, when the hero Prince Myshkin described his epileptic feelings of sublime sacredness of the inner light. Neurotheology is the science trying to understand the brain activities and to find an integration in religion concepts. TLE aura or psychic crisis is defined by simple or complex hallucinations, mystic divine experience, unpleasant experience of fear and déjà vu phenomenon. Neppe and Funkhouser (2006 described the notion as already seen, but it means also already heard,met, heard or visited. The“déjà vu” phenomenon is always a subjective experience which can appear in normal subjects or in pathologic states like TLE, schizophrenia or other types of psychosis. It can also be a subjective paranormal experience. Neppe’s definition is now universally used, defined as ‘any subjectively inappropriate impression of familiarity of the present experience with an undefined past’ (Neppe, 1983. Déjà vu has an impact on neuroscience and descriptions from history and literature and the multitude of descriptions from experiences demand various scientific explanations.

    The flexion relaxation phenomenon (FRP) can be defined as a reduction or silence of myoelectric activity of the lumbar erector spinae muscle during full trunk flexion. It is typically absent in patients with chronic low back pain (LBP). Before any broad clinical utilization of this neuromuscular response can be made, effective, standardized, and accurate methods of identifying FRP limits are needed. However, this phenomenon is clearly more difficult to detect for LBP patients than for healthy patients. The main goal of this study is to develop an automated method based on wavelet transformation that would improve time point limits detection of surface electromyography signals of the FRP in case of LBP patients. Conventional visual identification and proposed automated methods of time point limits detection of relaxation phase were compared on experimental data using criteria of accuracy and repeatability based on physiological properties. The evaluation demonstrates that the use of wavelet transform (WT) yields better results than methods without wavelet decomposition. Furthermore, methods based on wavelet per packet transform are more effective than algorithms employing discrete WT. Compared to visual detection, in addition to demonstrating an obvious saving of time, the use of wavelet per packet transform improves the accuracy and repeatability in the detection of the FRP limits. These results clearly highlight the value of the proposed technique in identifying onset and offset of the flexion relaxation response in LBP subjects.

    Based on different writings from different periods, this article gives us some of the psychodinamic view of musical phenomenon. It is divided in three parts. 1. The initial one is about general aspects of musical phenomenon. Music has a hihg power of symbolization, due to its ambiguity and simultaneity of elements. It can make a change on the common state of consciousness. Music also can influence on the Ego's cognitive style. Music has relationship with both the Ego's dissociative function and Ego's integrative function. 2. The secon part refers to the affective nature of music. Music release libidinal energy mainly through rhythm; for exemple we see the link between and dance in primitive societies. It also gives expression for emotional life, and arouses emotions too. 3. The third part refers to structural and functional aspects of music. This last part talks about the role of music to the listener and to the creative musician; it presents an analogy between the structure of the music and structure of the dreams. The joy of music involves the whole personality and music may be used to expand the Self.

    The mechanism of the phenomenon of sticking a pipeline moving in a well while pulled by the facility horizontal directional drilling is investigated. A quantitative evaluation of the force arising from sticking is given. At the same time, the working hypothesis takes a view of the combined effect of adhesion and friction interactions as the reasons that cause this phenomenon. As a measure to control the occurrence of sticking and to reduce the resistance force to movement of the pipeline in the well, several methods of ballasting the working pipeline are proposed, depending on the profile of the well and the ratio of the length of the curved sections of the inlet and outlet and the straight horizontal sections of the profile. It is shown that for crossings, which profile contains an extended horizontal section, it is possible to partially fill the pipeline with water to achieve zero buoyancy, and for crossings with curvature along the entire profile, the ballasting efficiency will be minimal.

    Following up on earlier investigations, the present paper analyzes construct validity of the impostor phenomenon. It examines the question whether the impostor phenomenon is a homogeneous construct or whether different types of persons with impostor self-concept can be distinguished on the basis of related characteristics. The study was conducted with professionals in leadership positions exhibiting a pronounced impostor self-concept (n = 183). Cluster-analytic procedures indicated the existence of two different types: one group which, in line with the literature (e.g., Clance, 1985), possessed traits classified as fairly unfavorable (“true impostors”) and another group which can be described as largely unencumbered (“strategic impostors”). The present study suggests two types of impostorism: “True” impostors characterized by the negative self-views associated with the construct definition, and more “strategic” impostors who seem to be less encumbered by self-doubt. It is assumed that “strategic impostors” are characterized by a form of deliberate self-presentation. Therefore, the impostor self-concept cannot principally be viewed as a dysfunctional personality style. This distinction should be more carefully considered in further research and in therapeutic interventions. PMID:28936188

    The purpose of this study was both to determine if the Impostor Phenomenon (IP) can be reliably and validly assessed in a Korean context and if so, evaluate the construct within the context of Jungian typology and the 5-factor model of personality. A sample of 654 Korean men and women were selected from 4 major Korean cities and administered the Clance Impostor Phenomenon Scale (CIPS; Clance & Imes, 1978) along with the Myers-Briggs Type Indicator (MBTI, Form G; Myers & McCaulley, 1985) and NEO Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992). Results indicated that the CIPS was very reliable, and the pattern of correlates suggested impostors to be introverted types on the MBTI. Results with the NEO-PI-R showed impostors to be very high on neuroticism and low on conscientiousness. This pattern of correlates is similar to other performance-inhibiting constructs such as fear of success and fear of failure. It was argued that IP be construed more as a motivational style than as a distinct clinical syndrome. The IP seems to be less pervasive in Korea than America and these cross-cultural implications were discussed.

    Full Text Available Purpose. We are going to analyze the understanding of simulacra in the works of the ancient philosopher Titus Lucretius Carus, to determine the features of the phenomenon of "simulacrum" in his paper "On the Nature of Things". Results and discussion. The results of the study were that the simulacrum of Lucretius was complexity and diversity. It was illustrated by the author of article, that the poetic work "On the Nature of Things", not just a poetry, but also deep philosophy and naturalistic system. Scientific innovation. It was discovered that the understanding of the simulacrum of Lucretius is a little explored field. The basis work for this research was “Lucretius and naturalism” G. Deleuze. Conclusions. The principal conclusion was that creativity Titus Lucretius Carus usually perceived as a manifestation of the Roman poetic word or description of the nature of things in a metaphorical form. However, in this article was made investigation of Lucretia’s interpretation of the phenomenon of "simulacrum".

    Controlling dynamical behavior of main coolant pumps shaftlines is an interesting subject for the user and the constructor. The first is mainly concerned by the interpretation of on field observed behavior, monitoring, reliability and preventive maintenance of his machines. The second must in addition manage with sometimes contradictory requirements related to mechanical design and performances optimization (shaft diameter reduction, clearance,...). The use of numerical modeling is now a classical technique for simple analysis (rough prediction of critical speeds for instance) but is still limited, in particular for vertical shaftline especially when equipped with hydrodynamic bearings, due to the complexity of encountered phenomenons in that type of machine. The vertical position of the shaftline seems to be the origin of non linear dynamical behavior, the analysis of which, as presented in the following discussion, requires specific modelization of fluid film, particularly for hydrodynamic bearings. The low static load generally no longer allows use of stiffness and damping coefficients classically calculated by linearizing fluid film equations near a stable static equilibrium position. For the analysis of such machines, specific numerical models have been developed at Electricite de France in a package for general rotordynamics analysis. Numerical models are briefly described. Then an example is precisely presented and discussed to illustrate some considered phenomenons and their consequences on machine behavior. In this example, the authors interpret the observed behavior by using numerical models, and demonstrate the advantage of such analysis for better understanding of vertical pumps rotordynamic

    The propagation of a high-power flat-topped Gaussian beam, which is modulated by three parallel wirelike scatterers, passing through a downstream Kerr medium slab and free spaces is investigated. A new phenomenon is found that a kind of intense fringe with intensity several times that of the incident beam can be formed in a plane downstream the Kerr medium. This kind of intense fringe is another result in the propagation process of nonlinear imaging and it locates scores of centimeters downstream the predicted hot image plane. Moreover, the intensity of this fringe can achieve the magnitude of that of hot image in corresponding single-scatterer case, and this phenomenon can arise only under certain conditions. As for the corresponding hot images, they are also formed but largely suppressed. The cause of the formation of such an intense fringe is analyzed and found related to interference in the free space downstream the Kerr medium. Moreover, the ways it is influenced by some important factors such as the wavelength of incident beam and the properties of scatterers and Kerr medium are discussed, and some important properties and relations are revealed.

    Full Text Available Measurement methods, based on the approach named Digital Stochastic Measurement, have been introduced, and several prototype and small-series commercial instruments have been developed based on these methods. These methods have been mostly investigated for various types of stationary signals, but also for non-stationary signals. This paper presents, analyzes and discusses digital stochastic measurement of electroencephalography (EEG signal in the time domain, emphasizing the problem of influence of the Wilbraham-Gibbs phenomenon. The increase of measurement error, related to the Wilbraham-Gibbs phenomenon, is found. If the EEG signal is measured and measurement interval is 20 ms wide, the average maximal error relative to the range of input signal is 16.84 %. If the measurement interval is extended to 2s, the average maximal error relative to the range of input signal is significantly lowered - down to 1.37 %. Absolute errors are compared with the error limit recommended by Organisation Internationale de Métrologie Légale (OIML and with the quantization steps of the advanced EEG instruments with 24-bit A/D conversion

    The fingertip blood flow measured by mercury strain gauge plethysmography with venous occlusion, at 22 degrees C room temperature, had significantly lower mean values in 190 patients with Raynaud's phenomenon (55 men aged 49 yrs +/- 16, 135 women aged 48 yrs +/- 16) than in 40 age and sex matched controls: 18 ml/100 ml/minute +/- 14.6 versus 35 ml/100 ml/minute +/- 15 at level p less than 0.01. The mean fingertip blood flow was significantly lower (p less than 0.01) in 31 cases of scleroderma and 32 cases of pulpar necrosis (respectively 13 ml +/- 13 and 11 ml +/- 8) than in 55 cases of primary Raynaud's disease (no detectable etiology and normal capillaroscopy 5 years after onset) or in 34 cases of mild Raynaud's phenomenon (respectively 21.6 +/- 16 and 24.4 +/- 18). A warming test (both hands in water at 45 degrees C during 3 minutes) was performed in 50 cases with low basal fingertip blood flow. It induced a "normalized" flow in 22 cases (mostly primary or mild Raynaud), a partly improved flow in 20 cases (mostly secondary Raynaud) and no improvement in 8 cases (scleroderma). The warming test appears to be clinically useful to assess the vasospasm and the vasodilating capabilities.

    Previous studies showed the appearance of many pairs of alpha tracks on the surface of the solid state nuclear track detectors (CR39) when exposed to radon. So the aim of this study was to judge whether this is a statistical or a physical phenomenon. Therefore, a theoretical function representing the probability of forming pairs of tracks on the detector was developed. A statistical studying was done for two sets of (1) mm thickness of CR39 detectors, the first set was exposed in the radon calibration chamber (RCC) with stable radon concentration (170 kBq/m 3 ) for different detectors positions inside and outside the exposure chamber (EC). While the second set was exposed to 241 Am source (1667 Bq) for different exposure times. The results show that the concentration of the single tracks on the detectors in case of covered EC was lower than the same situation without cover. In addition, the concentrations of the single tracks in various exposure situations inside and outside the EC were associated to the effective volumes that each detector sees. Finally, no considerable deference was found between pairs concentration in the two exposure cases (Radon chamber and 241 Am source), and both were lower than the theoretical values which calculated using the theoretical function. This means that pairs formation phenomena is a statistical phenomenon and there is no physical parameters related to radon gas or its daughter's behavior. (author)

    Dynamic cells scattering is one of the most efficient approaches exploring in measurements of cells size, morphology and growth states. This technique can be widely applied in real-time detection for pharmaceutical industry, food industry, liquor industry and other biological fields. A novel method named dynamic individual cells scattering measurement is designed in this paper, which can make cells pass through quartz glass measurement zone one by one with sheath flow driving force. During the experiments, an obvious phenomenon has been found which is called sheath flow dark zone phenomenon (SFDZ). Under the influence of SFDZ, sheath flow forming detection becomes very difficult. In this paper, the causes giving rise to SFDZ have been analyzed. And an improved method is put forward, in which the orifice inside the measurement zone is set as an optical system. Then the illuminating system is redesigned. In this way, almost all the illuminating light can enter orifice so that the total reflection energy decreases substantially. A comparison experiments have been done, which proves the efficiency of this redesigned optical system and its sound effects on SFDZ avoiding.

    Full Text Available Phenomenon of child abuse is considered to be voluntary or involuntary action of an adult which has a detrimental effect on child’s health and/or his psychophysical development. The concept of child abuse syndrome includes physical, mental and emotional maltreatment and negligence of physical, medical and emotional needs and also rape and sexual abuse. The authors conducted a questionnaire survey in order to assess children mistreatment by parents, caretakers and school environment. Studies included 228 high school students aged 14– 16 out of which 44,3% were girls and 55,7% were boys. 84% of the children were brought up by full families, 13% by mothers only, and 3% by fathers only. The most common form of mistreatment of children was physical violence (20,3%, psychological violence (12,1% and negligence (6,5%. Violence in the form of bad touch was experienced by 7,9% of girls and 0,8% of boys. High school students often suffered emotional violence from peers (22,9%, siblings (5,2% and teachers (4,8%. Results of the surveys were discussed paying attention to sociological context and legal conditions. The need for cooperation between many organizations and sectors of public life was highlighted to prevent the phenomenon of child abuse.

    Full Text Available Objectives: The coronary slow flow phenomenon (CSFP, characterized by decreased distal progression of dye to coronary arteries, is a distinct angiographic phenomenon and little is known about its pathophysiology. Although several hypotheses have been suggested, the underlying mechanism of CSFP has not been well established yet.The aim of this study was to determine the roles of indicators of dehydration and haemoconcentration in CSFP which have blood flow abnormality effects. Methods: The study consisted of 33 patients with CSFP (group 1, and 31 normal subjects as control group (group 2 detected by coronary angiography. CSFP was diagnosed by the TIMI frame count method. Serum electrolytes, osmolarity and haematological parameters were measured. Results: Compared with control subjects, patient with CSFP had increased levels of calculated osmolarity, tonicity, sodium, glucose and blood urea nitrogen (BUN. Significant differences were also observed in the haematocrit, haemoglobin concentration, and calculated osmolarity but not in total cholesterol and albumin. Conclusions: The results of the present study indicate that the markers of haemoconcentration and dehydration are significantly associated with CSFP. The markers may be important in the coronary blood flow anomaly.
