    Full Text Available Abstract Background Although cervical pain is widespread, most victims are only mildly and occasionally affected. A minority, however, suffer chronic pain and/or functional impairments. Although there is abundant literature regarding nontraumatic neck pain, little focuses on diagnostic criteria. During the last decade, research on neck pain has been designed to evaluate underlying pathophysiological mechanisms, without noteworthy success. Independent researchers have investigated postural balance and cervicocephalic kinesthetic sensibility among patients with chronic neck pain, and have (in most cases concluded the source of the problem is a reduced ability in the neck's proprioceptive system. Here, we investigated cervicocephalic kinesthetic sensibility and postural balance among patients with nontraumatic chronic neck pain. Methods Ours was a two-group, observational pilot study of patients with complaints of continuous neck pain during the 3 months prior to recruitment. Thirteen patients with chronic neck pain of nontraumatic origin were recruited from an institutional outpatient clinic. Sixteen healthy persons were recruited as a control group. Cervicocephalic kinesthetic sensibility was assessed by exploring head repositioning accuracy and postural balance was measured with computerized static posturography. Results Parameters of cervicocephalic kinesthetic sensibility were not reduced. However, in one of six test movements (flexion, global repositioning errors were significantly larger in the experimental group than in the control group (p Conclusion In patients with nontraumatic chronic neck pain, we found statistically significant global repositioning errors in only one of six test movements.

    Information about head orientation, position, and movement with respect to the trunk relies on the visual, vestibular, extensive muscular, and articular proprioceptive system of the neck. Various factors can affect proprioception since it is the function of afferent integration, and tuning of muscular and articular receptors. Pain, muscle fatigue, and joint position have been shown to affect proprioceptive capacity. Thus, it can be speculated that changes in body posture can alter the neck proprioception. This study was undertaken to investigate the effect of body posture on cervicocephalic kinesthetic sense in healthy subjects. Cervicocephalic kinesthetic sensibility was measured by the kinesthetic sensibility test in healthy young adults while in (a) habitual slouched sitting position with arms hanging by the side (SS), (b) habitual slouched sitting position with arms unloaded (supported) (SS-AS), and (c) upright sitting position with arms hanging by the side (US) during maximum and 30 degree right, left rotations, flexion, and extension. Thirty healthy male adults (mean age 27.83; SD 3.41) volunteered for this study. The least mean error was found for the SS-AS position (0.48; SD 0.24), followed by SS (0.60; SD 0.43) and US (0.96; SD 0.71), respectively. For all test conditions, there was significant difference in mean absolute error while head repositioning from maximum and 30 degree rotation during SS and SS-AS positions (p sense in both the horizontal and vertical planes. The findings of this study can be implemented in people who have to do repeated arm and neck movements, by using ergonomically effective chairs with proper arm supports. This might help in prevention and treatment of neck pain. PMID:27255483

    PURPOSE: To explore the frequency and patterns of brain infarction and other brain manifestations in cervicocephalic artery dissection (CCAD) and to evaluate the correlation between vessel wall findings and infarctions. MATERIAL AND METHODS: The medical records and films of 136 consecutive CCAD patients diagnosed in Oulu Univ. Hospital during the 20-year period since 1982 were reviewed. Five patients with no brain imaging were excluded. RESULTS: One-hundred-and-twenty-seven patients underwent cerebral CT and four patients MRI. Brain infarction was detected in 73 patients (56%), 43 of whom had cerebral infarction associated with anterior circulation dissection and 30 cerebellar infarction associated with posterior circulation dissection. Occlusion of the dissected vessel was accompanied by infarction in 76%, irregular stenosis in 40%, and other findings in 12%. Of the anterior circulation infarctions, territorial and subcortical infarctions and territorial infarctions with fragmentation, which are considered embolic, accounted for 95%, while only 5% were in the watershed area and considered hemodynamic. Intracranial posterior circulation dissection rarely caused infarction (in 1/11 of the dissected vessels), whereas intracranial anterior circulation dissection resulted in infarction more commonly (9/12). Altogether 23% of patients with intracranial CCAD had subarachnoid hemorrhage. Hemorrhagic transformation was present in five patients. CONCLUSIONS: More than half of CCAD patients have cerebral or cerebellar infarction at CT or conventional MR imaging. Occlusion of the dissected vessel is accompanied by infarction more often than other vessel wall abnormalities. Most cerebral infarctions caused by arterial dissections are of embolic origin. Intracranial dissections cause subarachnoid hemorrhage in more than 20% of patients.

    Musicians use different kinds of imagery. This review focuses on kinesthetic imagery, which has been shown to be an effective complement to actively playing an instrument. However, experience in actual movement performance seems to be a requirement for a recruitment of those brain areas representing movement ideation during imagery. An internal model of movement performance might be more differentiated when training has been more intense or simply performed more often. Therefore, with respect to kinesthetic imagery, these strategies are predominantly found in professional musicians. There are a few possible reasons as to why kinesthetic imagery is used in addition to active training; one example is the need for mental rehearsal of the technically most difficult passages. Another reason for mental practice is that mental rehearsal of the piece helps to improve performance if the instrument is not available for actual training as is the case for professional musicians when they are traveling to various appearances. Overall, mental imagery in musicians is not necessarily specific to motor, somatosensory, auditory, or visual aspects of imagery, but integrates them all. In particular, the audiomotor loop is highly important, since auditory aspects are crucial for guiding motor performance. All these aspects result in a distinctive representation map for the mental imagery of musical performance.

Overall, mental imagery in musicians is not necessarily specific to motor, somatosensory, auditory or visual aspects of imagery, but integrates them all.

    1980-01-01

    A universal force-reflecting hand controller has been developed which allows the establishment of a kinesthetic coupling between the operator and a remote manipulator. The six-degree-of-freedom controller was designed to generate forces and torques on its three positional and three rotational axes in order to permit the operator to accurately feel the forces encountered by the manipulator and be as transparent to operate as possible. The universal controller has been used in an application involving a six-degree-of-freedom mechanical arm equipped with a six-dimensional force-torque sensor at its base. In this application, the hand controller acts as a position control input device to the arm, while forces and torques sensed at the base of the mechanical hand back drive the hand controller. The positional control relation and the back driving of the controller according to inputs experienced by the force-torque sensor are established through complex mathematical transformations performed by a minicomputer. The hand controller is intended as a development tool for investigating force-reflecting master-slave manipulator control technology.

    Full Text Available Educational games for young children have boomed with the growing abundance of easy to use interfaces, especially on smartphones and tablets. In addition, most major gaming consoles boast of multimodal interaction, including the more novel and immersive gesture-based or bodily interaction; a concept proved by masses of consumers including young children.  In this paper, we examine an elementary mathematics learning application that aims to promote a state of flow for children aged between 6-8 years. The application is run on a PC and uses the Microsoft Kinect sensor for motion tracking. It provides gamified approaches to teach the number system between 0-20. Our underlying hypothesis is that kinesthetic learning methods supported by bodily interaction provide leverage to different types of learners.The paper describes the results of two sets (n1=23, n2=44 of pilot tests for exercise application for PC and Kinect. The tools utilized include a short and simplified survey for the children, and another survey and open-ended questionnaire for the teachers. Our key findings relate to the user experience of gesture-based interaction and show how the gesture modality promotes flow. Furthermore, we discuss our preliminary assessment on several learning related themes.

    Objective. Attention is known to modulate the plasticity of the motor cortex, and plasticity is crucial for recovery in motor rehabilitation. This study addresses the possibility of using an EEG-based brain-computer interface (BCI) to detect kinesthetic attention to movement. Approach. A novel experiment emulating physical rehabilitation was designed to study kinesthetic attention. The protocol involved continuous mobilization of lower limbs during which participants reported levels of attention to movement—from focused kinesthetic attention to mind wandering. For this protocol an asynchronous BCI detector of kinesthetic attention and deliberate mind wandering was designed. Main results. EEG analysis showed significant differences in theta, alpha, and beta bands, related to the attentional state. These changes were further pinpointed to bands relative to the frequency of the individual alpha peak. The accuracy of the designed BCI ranged between 60.8% and 68.4% (significantly above chance level), depending on the used analysis window length, i.e. acceptable detection delay. Significance. This study shows it is possible to use self-reporting to study attention-related changes in EEG during continuous mobilization. Such a protocol is used to develop an asynchronous BCI detector of kinesthetic attention, with potential applications to motor rehabilitation.

    CERN Document Server

    Bruun, Jesper

    2014-01-01

    One of the major difficulties in learning physics is for students to develop a conceptual understanding of the core concepts of physics. Many authors have argued that student conceptions of basic physical phenomena are rooted in basic schemas, originating in fundamental kinesthetic experiences of being. If central schemas have a bodily basis, this idea should be utilized in physics instruction. Thus, we argue that kinesthetic activities, including careful experiential and conceptual analysis will provide useful entry point for student acquisition of the basic conceptions of physics, and can overcome the phenomenological gap between the experiential and the conceptual understanding. We discuss the nature of image schemas and focus particularly on one: effort-resistance-flow. We argue that this schema is fundamental not only in our everyday experience, but also in most of school physics. We provide an example of a kinesthetic model and describe how an instructional strategy of these exercises can support studen...

    Morrow, C. A.; Zawaski, M.

    2004-12-01

    This paper will report on a significant upgrade to the first in a series of innovative, experiential lessons we call Kinesthetic Astronomy. The Sky Time lesson reconnects students with the astronomical meaning of the day, year, and seasons. Like all Kinesthetic Astronomy lessons, it teaches basic astronomical concepts through choreographed bodily movements and positions that provide educational sensory experiences. They are intended for sixth graders up through adult learners in both formal and informal educational settings. They emphasize astronomical concepts and phenomenon that people can readily encounter in their "everyday" lives such as time, seasons, and sky motions of the Sun, Moon, stars, and planets. Kinesthetic Astronomy lesson plans are fully aligned with national science education standards, both in content and instructional practice. Our lessons offer a complete learning cycle with written assessment opportunities now embedded throughout the lesson. We have substantially strengthened the written assessment options for the Sky Time lesson to help students translate their kinesthetic and visual learning into the verbal-linguistic and mathematical-logical realms of expression. Field testing with non-science undergraduates, middle school science teachers and students, Junior Girl Scouts, museum education staff, and outdoor educators has been providing evidence that Kinesthetic Astronomy techniques allow learners to achieve a good grasp of concepts that are much more difficult to learn in more conventional ways such as via textbooks or even computer animation. Field testing of the Sky Time lesson has also led us to significant changes from the previous version to support student learning. We will report on the nature of these changes.

  13. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Directory of Open Access Journals (Sweden)

    Rashmika Pandya

    2011-02-01

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other.

  16. Robot-assisted training of the kinesthetic sense: enhancing proprioception after stroke

    Full Text Available Proprioception has a crucial role in promoting or hindering motor learning. In particular, an intact position sense strongly correlates with the chances of recovery after stroke. A great majority of neurological patients present both motor dysfunctions and impairments in kinesthesia, but traditional robot and virtual reality training techniques focus either in recovering motor functions or in assessing proprioceptive deficits. An open challenge is to implement effective and reliable tests and training protocols for proprioception that go beyond the mere position sense evaluation and exploit the intrinsic bidirectionality of the kinesthetic sense, which refers to both sense of position and sense of movement. Modulated haptic interaction has a leading role in promoting sensorimotor integration and it is a natural way to enhance volitional effort. Therefore, we designed a preliminary clinical study to test a new proprioception-based motor training technique for augmenting kinesthetic awareness via haptic feedback. The feedback was provided by a robotic manipulandum and the test involved 7 chronic hemiparetic subjects over three weeks. The protocol included evaluation sessions, that consisted of a psychometric estimate of the subject’s kinesthetic sensation, and training sessions, in which the subject executed planar reaching movements in the absence of vision and under a minimally assistive haptic guidance made by sequences of graded force pulses. The bidirectional haptic interaction between the subject and the robot was optimally adapted to each participant in order to achieve a uniform task difficulty over the workspace. All the subjects consistently improved in the perceptual scores as a consequence of training. Moreover, they could minimize the level of haptic guidance in time. Results suggest that the proposed method is effective in enhancing kinesthetic acuity, but the level of impairment may affect the ability of subjects to retain their

  18. Kinesthetic and Vestibular Information Modulate Alpha Activity during Spatial Navigation: A Mobile EEG Study

    Full Text Available In everyday life, spatial navigation involving locomotion provides congruent visual, vestibular and kinesthetic information that need to be integrated. Yet, previous studies on human brain activity during navigation focus on stationary setups, neglecting vestibular and kinesthetic feedback. The aim of our work is to uncover the influence of those sensory modalities on cortical processing. We developed a fully immersive virtual reality setup combined with high-density mobile electroencephalography (EEG. Participants traversed one leg of a triangle, turned on the spot, continued along the second leg and finally indicated the location of their starting position. Vestibular and kinesthetic information was provided either in combination, as isolated sources of information or not at all within a 2x2 full factorial intra-subjects design. EEG data were processed by clustering independent components, and time-frequency spectrograms were calculated. In parietal, occipital and temporal clusters, we detected alpha suppression during the turning movement, which is associated with a heightened demand of visuo-attentional processing, and closely resembles results reported in previous stationary studies. This decrease is present in all conditions and therefore seems to generalize to more natural settings. Yet, in incongruent conditions, when different sensory modalities did not match, the decrease is significantly stronger. Additionally, in more anterior areas, we found that providing only vestibular but no kinesthetic information results in alpha increase. These observations demonstrate that stationary experiments omit important aspects of sensory feedback. Therefore, it is important to develop more natural experimental settings in order to capture a more complete picture of neural correlates of spatial navigation.

    2015-06-01

    Full Text Available OBJECTIVE: To verify the methods used by the clinical trials that assessed the effect of tactile/kinesthetic stimulation on weight gain in preterm infants and highlight the similarities and differences among such studies. SOURCES: This review collected studies from two databases, PEDro and PubMed, in July of 2014, in addition to bibliographies. Two researchers assessed the relevant titles independently, and then chose which studies to read in full and include in this review by consensus. Clinical trials that studied tactile stimulation or massage therapy whether or not associated with kinesthetic stimulation of preterm infants; that assessed weight gain after the intervention; that had a control group and were composed in English, Portuguese, or Spanish were included. SUMMARY OF THE FINDINGS: A total of 520 titles were found and 108 were selected for manuscript reading. Repeated studies were excluded, resulting in 40 different studies. Of these, 31 met all the inclusion criteria. There were many differences in the application of tactile/kinesthetic stimulation techniques among studies, which hindered the accurate reproduction of the procedure. Also, many studies did not describe the adverse events that occurred during stimulation, the course of action taken when such events occurred, and their effect on the outcome. CONCLUSIONS: These studies made a relevant contribution towards indicating tactile/kinesthetic stimulation as a promising tool. Nevertheless, there was no standard for application among them. Future studies should raise the level of methodological rigor and describe the adverse events. This may permit other researchers to be more aware of expected outcomes, and a standard technique could be established.

  2. Effects of kinesthetic versus visual imagery practice on two technical dance movements: a pilot study.

    2012-03-01

    Motor imagery is a type of mental practice that involves imagining the body performing a movement in the absence of motor output. Dance training traditionally incorporates mental practice techniques, but quantitative effects of motor imagery on the performance of dance movements are largely unknown. This pilot study compared the effects of two different imagery modalities, external visual imagery and kinesthetic imagery, on pelvis and hip kinematics during two technical dance movements, plié and sauté. Each of three female dance students (mean age = 19.7 years, mean years of training = 10.7) was assigned to use a type of imagery practice: visual imagery, kinesthetic imagery, or no imagery. Effects of motor imagery on peak external hip rotation varied by both modality and task. Kinesthetic imagery increased peak external hip rotation for pliés, while visual imagery increased peak external hip rotation for sautés. Findings suggest that the success of motor imagery in improving performance may be task-specific. Dancers may benefit from matching imagery modality to technical tasks in order to improve alignment and thereby avoid chronic injury. PMID:22390952

  7. Brain Regions Associated to a Kinesthetic Illusion Evoked by Watching a Video of One's Own Moving Hand.

    Directory of Open Access Journals (Sweden)

    Fuminari Kaneko

    Full Text Available It is well known that kinesthetic illusions can be induced by stimulation of several sensory systems (proprioception, touch, vision…. In this study we investigated the cerebral network underlying a kinesthetic illusion induced by visual stimulation by using functional magnetic resonance imaging (fMRI in humans. Participants were instructed to keep their hand still while watching the video of their own moving hand (Self Hand or that of someone else's moving hand (Other Hand. In the Self Hand condition they experienced an illusory sensation that their hand was moving whereas the Other Hand condition did not induce any kinesthetic illusion. The contrast between the Self Hand and Other Hand conditions showed significant activation in the left dorsal and ventral premotor cortices, in the left Superior and Inferior Parietal lobules, at the right Occipito-Temporal junction as well as in bilateral Insula and Putamen. Most strikingly, there was no activation in the primary motor and somatosensory cortices, whilst previous studies have reported significant activation in these regions for vibration-induced kinesthetic illusions. To our knowledge, this is the first study that indicates that humans can experience kinesthetic perception without activation in the primary motor and somatosensory areas. We conclude that under some conditions watching a video of one's own moving hand could lead to activation of a network that is usually involved in processing copies of efference, thus leading to the illusory perception that the real hand is indeed moving.

    1978-01-01

    The debate on energy problems has occasionally been marked by an emotional rather than an objective approach. Expertise and balanced view-points will therefore have to dominate the scene again to put things into proper perspective. In the past electricity has made a vital contribution to the growth of productivity. It has helped to improve working conditions and brought better comfort and advances to the community in general. Competition with other forms of energy made it necessary for electricity to be used efficiently. The future aim will be to further developments towards the sensible and purposeful use of electricity. Perfectionism and opportunism are out of place.

  15. Adjusting ability and sensibility for an accident

    International Nuclear Information System (INIS)

    Adjusting ability (technical competence) and sensibility (consciousness) are the two most important priorities any staff member of any organization should bear in mind while acting during a nuclear or radiological emergency. The discussion is aimed at the national authorities of states which do not have a major nuclear power reactor programme, and especially at the IAEA and WHO: although a decade has gone by, the lessons from the radiological accident in Goiania have not been fully learned. The events which unravelled in the fall of 1987 took the population of the city of Goiania completely by surprise: they did not comprehend what had happened and failed to grasp what measures needed to be taken, a situation which precipitated a very complex psychological reaction, coupled with discrimination. To ensure the safety of radiation sources and nuclear installations, national and international organizations should direct their efforts towards educating and training staff in developing countries who work with ionizing radiation and promoting organizational capacity. This should be done first, by improving safety qualitatively so as to better control the uses of radioactive materials in medicine, agriculture, industry and research, and secondly, by assisting countries without a major nuclear power reactor programme to develop an objective and realistic emergency response training programme.

    A heat pipe cooling system which employs a sensible heat sink is discussed. With this type of system, incident aerodynamic heat is transported via a heat pipe from the stagnation region to the heat sink and absorbed by raising the temperature of the heat sink material. The use of a sensible heat sink can be advantageous for situations where the total mission heat load is limited, as it is during re-entry, and a suitable radiation sink is not available.

    Full Text Available The purpose of this study was to compare the effect of training using internal imagery (IMI; also known as kinesthetic imagery or first person imagery with that of external imagery (EMI; also known as third-person visual imagery of strong muscle contractions on voluntary muscle strengthening. Eighteen young, healthy subjects were randomly assigned to one of three groups (6 in each group: internal motor imagery (IMI, external motor imagery (EMI, or a no-practice control (CTRL group. Training lasted for 6 weeks (~15 min/day, 5 days/week. The participants’ right arm elbow-flexion strength, muscle electrical activity and movement-related cortical potential (MRCP were evaluated before and after training. Only the IMI group showed significant strength gained (10.8% while the EMI (4.8% and CTRL (-3.3% groups did not. Only the IMI group showed a significant elevation in MRCP on scalp locations over both the primary motor (M1 and supplementary motor cortices (EMI group over M1 only and this increase was significantly greater than that of EMI and CTRL groups. These results suggest that training by IMI of forceful muscle contractions was effective in improving voluntary muscle strength without physical exercise. We suggest that the IMI training likely strengthened brain-to-muscle (BTM command that may have improved motor unit recruitment and activation, and led to greater muscle output. Training by internal motor imagery of forceful muscle contractions may change the activity level of cortical motor control network, which may translate into greater descending command to the target muscle and increase its strength.

    Perez-Davis, Marla E.; Gaier, James R.; Petrefski, Chris

    1991-01-01

    A sensible heat receiver is considered which uses a vapor grown carbon fiber-carbon (VGCF/C) composite as the thermal storage medium and which was designed for a 7-kW Brayton engine. This heat receiver stores the required energy to power the system during eclipse in the VGCF/C composite. The heat receiver thermal analysis was conducted through the Systems Improved Numerical Differencing Analyzer and Fluid Integrator (SINDA) software package. The sensible heat receiver compares well with other latent and advanced sensible heat receivers analyzed in other studies, while avoiding the problems associated with latent heat storage salts and liquid metal heat pipes. The concept also satisfies the design requirements for a 7-kW Brayton engine system. The weight and size of the system can be optimized by changes in geometry and technology advances for this new material.

    Full Text Available OBJECTIVE: Motor imagery (MI has been recently considered as an adjunct to physical rehabilitation in patients with multiple sclerosis (MS. It is necessary to assess MI abilities and benefits in patients with MS by using a reliable tool. The Kinesthetic and Visual Imagery Questionnaire (KVIQ was recently developed to assess MI ability in patients with stroke and other disabilities. Considering the different underlying pathologies, the present study aimed to examine the validity and reliability of the KVIQ in MS patients. METHOD: Fifteen MS patients were assessed using the KVIQ in 2 sessions (5-14days apart by the same examiner. In the second session, the participants also completed a revised MI questionnaire (MIQ-R as the gold standard. Intra-class correlation coefficients (ICCs were measured to determine test-retest reliability. Spearman's correlation analysis was performed to assess concurrent validity with the MIQ-R. Furthermore, the internal consistency (Cronbach's alpha and factorial structure of the KVIQ were studied. RESULTS: The test-retest reliability for the KVIQ was good (ICCs: total KVIQ=0.89, visual KVIQ=0.85, and kinesthetic KVIQ=0.93, and the concurrent validity between the KVIQ and MIQ-R was good (r=0.79. The KVIQ had good internal consistency, with high Cronbach's alpha (alpha=0.84. Factorial analysis showed the bi-factorial structure of the KVIQ, which was explained by visual=57.6% and kinesthetic=32.4%. CONCLUSIONS: The results of the present study revealed that the KVIQ is a valid and reliable tool for assessing MI in MS patients.

    The feasibility of using the critical tracking task to evaluate kinesthetic-tactual displays was examined. The test subjects were asked to control a first-order unstable system with a continuously decreasing time constant by using either visual or tactual unidimensional displays. The results indicate that the critical tracking task is both a feasible and a reliable methodology for assessing tactual tracking. Further, that the critical tracking methodology is as sensitive and valid a measure of tactual tracking as visual tracking is demonstrated by the approximately equal effects of quickening for the tactual and visual displays.

    A new method for deduction of the sensible heat flux is validated with three sets of published SODAR (sound detection and ranging)data.Although the related expressions have previously been confirmed by the author with surface layer data,they have not yet been validated with observations from the boundary layer before this work.In the study,selected SODAR data are used to test the method for the convective boundary layer.The sensible heat flux(SHF)retrieved from SODAR data is found to decrease linearly with height in the mixed layer.The surface sensible heat fluxes derived from the deduced sensible heat flux profiles under convective conditions agree well with those measured by the eddy correlation method.The characteristics of SHF profiles deduced from SODAR data in difierent places reflect the background meteorology and terrain.The upper part of the SHF profile(SHFP)for a complicated terrain is found to have a difierent slope from the lower part.It is suggested that the former reflects the advective chaxacteristic of turbulence in upwind topography.A similarity relationship for the estimation of SHFP in a well mixed layer with surface SHF and zero-heat-flux layer height is presented.

    Bennett, Timothy J.; Lacy, Dovie E.

    1988-01-01

    NASA Lewis, through in-house efforts, has begun a study to generate a conceptual design of a sensible heat solar receiver and to determine the feasibility of such a system for space power applications. The sensible heat solar receiver generated in this study uses pure lithium as the thermal storage medium and was designed for a 7 kWe Brayton (PCS) operating at 1100 K. The receiver consists of two stages interconnected via temperature sensing variable conductance sodium heat pipes. The lithium is contained within a niobium vessel and the outer shell of the receiver is constructed of third generation rigid, fibrous ceramic insulation material. Reradiation losses are controlled with niobium and aluminum shields. By nature of design, the sensible heat receiver generated in this study is comparable in both size and mass to a latent heat system of similar thermal capacitance. The heat receiver design and thermal analysis were conducted through the combined use of PATRAN, SINDA, TRASYS, and NASTRAN software packages.

  14. Distributed Sensible Heat Flux Measurements for Wireless Sensor Networks

    Huwald, H.; Brauchli, T.; Lehning, M.; Higgins, C. W.

    2015-12-01

    The sensible heat flux component of the surface energy balance is typically computed using eddy covariance or two point profile measurements while alternative approaches such as the flux variance method based on convective scaling has been much less explored and applied. Flux variance (FV) certainly has a few limitations and constraints but may be an interesting and competitive method in low-cost and power limited wireless sensor networks (WSN) with the advantage of providing spatio-temporal sensible heat flux over the domain of the network. In a first step, parameters such as sampling frequency, sensor response time, and averaging interval are investigated. Then we explore the applicability and the potential of the FV method for use in WSN in a field experiment. Low-cost sensor systems are tested and compared against reference instruments (3D sonic anemometers) to evaluate the performance and limitations of the sensors as well as the method with respect to the standard calculations. Comparison experiments were carried out at several sites to gauge the flux measurements over different surface types (gravel, grass, water) from the low-cost systems. This study should also serve as an example of spatially distributed sensible heat flux measurements.

  15. Three symptoms of contemporary social sensibility in Mexico

    Directory of Open Access Journals (Sweden)

    Armando Villegas Contreras

    2015-12-01

    Full Text Available In this essay various characteristics of social contemporary sensibility are analyzed. Three images depicting the recent violence in Mexico are assumed as symptoms. These images are examples of the manner in which violence and cruelty are presented by the media in the world today. They are a photograph from the Mexican weekly Proceso for an article involving femicide in Ciudad Juárez, the photograph of a student murdered during the Ayotzinapa events, in the Mexican state of Guerrero, and the work by the artist Teresa Margolles: PM 2010. Even though the images are shown on different mediums, the three allow for the problematization, each in its own way, of the production and reproduction of violence during recent years in Mexico. However, the three images can be used to exemplify the general contemporary assumption in regard to “lives that do not matter”. This violence corresponds in some instances to a lack of social sensibility that due to the media experience results in creating a distance between those of us who “see” cruelty as entertainment or a spectacle and those who are the victims of such cruelty. In other instances, violence is the correlate of a sensibility that accepts and legitimizes it thus allowing its reproduction.

  6. Irradiation sensibility of different provenances of Jatropha curcas L. seeds

    International Nuclear Information System (INIS)

    The irradiation sensibility of 10 provenances of Jatropha curcas L. seeds to 60Co γ-rays was studied. The results showed that the relationship between relative germination rate of the seeds and the doses of irradiation was negative correlation, and the difference of relative germination rate among different doses treatment was significant at 5% probability level or highly significant at 1% probability level. For seeds of different provenances, the correlation coefficient of linear regression was from -0.89--0.96, and the medial lethal doses (LD 50) of 10 provinces was from 127 Gy to 184 Gy. According to the LD 50, we could divided 10 provinces of J. curcas L. into sensitive provenance, transitional provenances and obtuse provenances. The provenances of Yuanjiang , Yunan (184 Gy) belonged to sensitive provenance; the provenances of Zhenfeng, Guizhou (127 Gy) and the provenances of Yuedong, Hainan (141 Gy) belonged to obtuse provenance; other 7 provenances belonged to transitional provenances. The results provided important experiment basis for germ plasma resources innovation of J. curcas L. (authors)

  7. Comparison between different methods of measurement of momentum and sensible heat fluxes over canopies

    1997-01-01

    Full Text Available Différent methods of measurement of momentum and sensible heat flux densifies are presented and compared above a gras covered fallow. The aerodynamic (AD and eddy covariance (EC methods are presented and compared for both momentum and sensible heat measurements. In addition, the temperature fluctuation (TF method is compared to the HEC method for the sensible heat flux measurement. The AD and EC methods are in good agreement for the momentum flux measurements. For the sensible heat flux, the AD method is very sensible to temperature errors. So it is unusable during night and gives biased estimations during the day. The TF method gives only estimations of the sensible heat flux. It is in good agreement with the EC method during the day but diverges completely during night, being unable to disceming positive from négative fluxes. From the three methods, the EC method is the sole that allows to measure continuously both momentum and sensible heat flux but it requires a loud data treatment. We présent in this paper the algorithm used for this treatment.

    The electrical conductivity,compression sensibility,workability and cost are factors that affect the application of conductive smart materials in civil structures.Consequently,the resistance and compression sensibility of magnetic-concentrated fly ash (MCFA) mortar were investigated using two electrode method,and the difference of compression sensibility between MCFA mortar and carbon fiber reinforced cement (CFRC)under uniaxial loading was studied.Factors affecting the compression sensibility of MCFA mortar,such as MCFA content,loading rate and stress cycles,were analyzed.Results show that fly ash with high content of Fe3O4 can be used to prepare conductive mortar since Fe3O4 is a kind of nonstoichiometric oxide and usually acts as semiconductor.MCFA mortar exhibits the same electrical conductivity to that of CFRC when the content of MCFA is more than 40% by weight of sample.The compression sensibility of mortar is improved with the increase of MCFA content and loading rate.The compression sensibility of MCFA mortar is reversible with the circling of loading.Results show that the application of MCFA in concrete not only provides excellent performances of electrical-functionality and workability,but also reduces the cost of conductive concrete.

    The current study used functional magnetic resonance imaging to examine the neural activity of an expert dancer with 35 years of break-dancing experience during the kinesthetic motor imagery (KMI) of dance accompanied by highly familiar and unfamiliar music. The goal of this study was to examine the effect of musical familiarity on neural activity underlying KMI within a highly experienced dancer. In order to investigate this in both primary sensory and motor planning cortical areas, we examined the effects of music familiarity on the primary auditory cortex [Heschl's gyrus (HG)] and the supplementary motor area (SMA). Our findings reveal reduced HG activity and greater SMA activity during imagined dance to familiar music compared to unfamiliar music. We propose that one's internal representations of dance moves are influenced by auditory stimuli and may be specific to a dance style and the music accompanying it. PMID:25301352

  18. "Lesbians are not women": feminine and lesbian sensibilities in Harmony Hammond's late-1970s sculpture.

    Science.gov (United States)

    Thompson, Margo Hobbs

    2008-01-01

    Harmony Hammond's wrapped fabric sculptures are placed in context of the theories of gender and sexuality that circulated among lesbian and straight feminists at the time they were made, the late 1970s. Hammond has cited in particular Monique Wittig's novels, such as The Lesbian Body, and her essays including "The Straight Mind" where Wittig concludes that the lesbian is not a woman. The critique to which Wittig's lesbian separatism has been subjected by Judith Butler in her consideration of the appeal and limitations of essentialism also applies to Hammond's art. Hammond's use of vaginal imagery was instrumental to visualizing a lesbian sensibility, but the proposition of such a sensibility established a new problematic: a new essential category. The article concludes that because Hammond's work was produced in the context of a complex set of discourses, lesbian, feminist, and aesthetic, it resisted reduction to a singular meaning. Her sculptures avoided the pitfall of substituting one essence for another, lesbian for feminine sensibility, but activated both. The sculptures effectively queered vaginal imagery: When Hammond used vaginal imagery to represent lesbian sensibility, she subverted the equation of sex and gender and the essentialist notion of feminine sensibility.

  19. A Bayesian approach to estimate sensible and latent heat over vegetation

    Directory of Open Access Journals (Sweden)

    C. van der Tol

    2009-03-01

    Full Text Available Sensible and latent heat fluxes are often calculated from bulk transfer equations combined with the energy balance. For spatial estimates of these fluxes, a combination of remotely sensed and standard meteorological data from weather stations on the ground is used. The success of this approach depends on the accuracy of the input data and on the accuracy of two variables in particular: aerodynamic and surface conductance. This paper presents a Bayesian approach to improve estimates of sensible and latent heat fluxes by using a priori estimates of aerodynamic and surface conductance alongside remote measurements of surface temperature. The method is validated for time series of half-hourly measurements in a fully grown maize field, a vineyard and a forest. It is shown that the Bayesian approach yields more accurate estimates of sensible and latent heat flux than traditional methods.

Upon statistic adjustment, it still did not show obvious difference (P>0.05). In case of joint implementation of 9402 and 60Co γ, the sensibility ratio is 1.02. Conclusion: 9402 has no obvious effect to the sensibility of normal small intestinal crypts. (authors)

  2. Tests of a robust eddy correlation system for sensible heat flux

    Blanford, J. H.; Gay, L. W.

    1992-03-01

    Sensible heat flux estimates from a simple, one-propeller eddy correlation system (OPEC) were compared with those from a sonic anemometer eddy correlation system (SEC). In accordance with similarity theory, the performance of the OPEC system improved with increasing height of the sensor above the surface. Flux totals from the two systems at sites with adequate fetch were in excellent agreement after frequency response corrections were applied. The propeller system appears suitable for long periods of unattended measurement. The sensible heat flux measurements can be combined with net radiation and soil heat flux measurements to estimate latent heat as a residual in the surface energy balance.

  6. Climate forcing and response to idealized changes in surface latent and sensible heat

    International Nuclear Information System (INIS)

    Land use and land cover changes affect the partitioning of latent and sensible heat, which impacts the broader climate system. Increased latent heat flux to the atmosphere has a local cooling influence known as 'evaporative cooling', but this energy will be released back to the atmosphere wherever the water condenses. However, the extent to which local evaporative cooling provides a global cooling influence has not been well characterized. Here, we perform a highly idealized set of climate model simulations aimed at understanding the effects that changes in the balance between surface sensible and latent heating have on the global climate system. We find that globally adding a uniform 1 W m-2 source of latent heat flux along with a uniform 1 W m-2 sink of sensible heat leads to a decrease in global mean surface air temperature of 0.54 ± 0.04 K. This occurs largely as a consequence of planetary albedo increases associated with an increase in low elevation cloudiness caused by increased evaporation. Thus, our model results indicate that, on average, when latent heating replaces sensible heating, global, and not merely local, surface temperatures decrease.

    1994-07-01

    The major focus of research on alcohol is not on the majority who drink without problems, but on the small minority who have extreme problems. Difficulty in conceiving, measuring, and analyzing non-problem drinking lies in the exclusively problem-drinking orientation of most drinking measures. Drawing on conventionally used scales (e.g. Short Michigan Alcoholism Screening Test) and other established concepts in the alcohol literature (e.g. craving, hangover), a set of 24 items was selected to classify all persons in a sample from Tecumseh, Michigan, as to their alcohol-related behaviors (N = 1266). A Sensible-Problem Drinking Classification (SPDC) was developed with five categories: very sensible, sensible, borderline, problem, and impaired. A variety of known alcohol and psychosocial variables were related monotonically across these categories in expected directions. Ethanol ounces per week was only modestly related to SPDC groups: R2 = 0.09 for women, R2 = 0.21 for men. The positive relationship of problem and non-problem SPDC groups to high and low blood pressure was P = 0.07, while ethanol (oz/week) was uncorrelated to blood pressure (mm Hg) in this subsample (N = 453). The development of SPDC requires additional items measuring self and group regulatory alcohol behavior. However, this initial analysis of no-problem subgroups has direct import for public health regulation of alcohol use by providing a model of a sensible view of alcohol use. PMID:7986282

  11. Effects of learning-style environmental and tactal/kinesthetic preferences on the understanding of scientific terms and attitude test scores of fifth-grade students

    Science.gov (United States)

    Sullivan, Angela Tirino

    This investigator analyzed the effects of learning-style environmental and tactual/kinesthetic preferences on the understanding of scientific terms and attitude test scores of fifth-grade students. To identify individual preferences, the Learning-Styles Inventory (Dunn, Dunn & Price, 1996) was administered to students who attended a suburban elementary school. Forty-six general education students were given instruction through the gradual establishment of an environmentally- and perceptually-responsive learning-style classroom. Instructional units were divided into three phases of two weeks each. The units of scientific terms were instructed for varied learning-style preferences and were gradually introduced during these instructional phases: Phase 1: Electricity was taught with traditional teaching methods; Phase 2: The Source of Energy was taught with accommodations for sound, light, temperature, design elements; Phase 3: Pollution was taught with accommodations for tactual/kinesthetic modalities. Pre and Post-tests, were administered in each of the three phases to determine scientific term gains. A repeated measures ANOVA and General Linear Model were employed to compare mean gains from phase to phase. Post-hoc comparisons were performed using the Bonferroni method and similar procedures were conducted on the Semantic Differential Scales (Pizzo, 1981). Correlations of relative gain scores during each phase were assessed by means of Pearson-product-moment correlations. Differences in the strengths of correlated correlations were evaluated by means of t-tests for related correlation coefficients. Significant gains were found when students were instructed employing incremental learning-styles strategies. To determine attitudinal changes toward science terms, the Semantic Differential Scale (Pizzo, 1981) was administered three times throughout this study: after Phase 1, traditional teaching; Phases 2 and 3, after learning-styles intervention.

    Pouring hot water from a kettle into a cup may prove a hazardous task, especially for the elderly or the visually-impaired. Individuals with deteriorating eyesight may endanger their hands by performing this task with both hands, relaying on tactilo-kinesthetic feedback (TKF). Auditory feedback (AF) may allow them to perform the task singlehandedly, thereby reducing the risk for injury. However since relying on an AF is not intuitive and requires practice, we aimed to determine if AF supplied during the task of pouring water can be used naturally as visual feedback (VF) following practice. For this purpose, we quantified, in young healthy sighted subjects (n = 20), the performance and kinematics of pouring water in the presence of three isolated feedbacks: visual, tactilo-kinesthetic, or auditory. There were no significant differences between the weights of spilled water in the AF condition compared to the TKF condition in the first, fifth or thirteenth trials. The subjectively-reported difficulty levels of using the TKF and the AF were significantly reduced between the first and thirteenth trials for both TKF (p = 0.01) and AF (p = 0.001). Trunk rotation during the first trial using the TKF was significantly lower than the trunk rotation while using VF. Also, shoulder adduction during the first trial using the TKF was significantly higher than the shoulder adduction while using the VF. During the AF trials, the median travel distance of the tip of the kettle was significantly reduced in the first trials so that in the thirtieth trial it did not differ significantly from the median travel distance during the thirtieth trial using TKF and VF. The maximal velocity of the tip of the kettle was constant for each of the feedback conditions but was higher in 10 cm s(-1) using VF than TKF, which was higher in 10 cm s(-1) from using AF. The smoothness of movement of the TKF and AF conditions, expressed by the normalized jerk score (NJSM), was one and two orders

  14. Effects of Surface Sensible Heat Fluxes on the Tropical Cyclone Intensity

    Ma, Zhanhong; Fei, Jianfang

    2016-04-01

    The contributions of surface sensible heat fluxes (SHX) to the evolution of tropical cyclone (TC) intensity and structure are examined in this study by conducting cloud-resolving simulations. Results suggest that although the peak values of SHX could account for nearly 30% of those of the total surface latent and sensible heat fluxes, the impact of SHX on TC intensification is nonetheless not distinct. However, the TC size shows great sensitivity to the SHX that the storm is shrunk by over 20% after removing the SHX. The reduced total surface enthalpy fluxes due to the removal of SHX do not necessarily result in weakened TCs, while the larger surface latent heat fluxes (LHX) basically correspond to stronger TCs. This suggests that the TC intensity is largely dependent on the LHX rather than the total surface enthalpy fluxes, although the latter is generally dominated by the former.

    Field observations of the atmospheric boundary layer were made over urban and suburban terrain in the Yangtze River Delta, China. A multiresolution decomposition was applied over three different types of terrain: flat homogeneous terrain, suburban terrain and urban terrain, with results indicating that, (1) the average scale contribution of u, v, w and Tv had a similar variability with length scale for all these three sites respectively, and the dimensionless length scale corresponding to the maximum sensible heat flux contribution increased with the terrain complexity; (2) the length scale corresponding to the maximal average scale contribution for vertical wind velocity λ _w was directly proportional to the roughness length z0 in unstable conditions; and (3) the contributions of large-scale motions led to sensible heat fluxes determined with a large-aperture scintillomter being larger than those using the eddy-covariance method for the suburban case, whereas this phenomenon was not substantial for the urban case.

    Sensible heat flux (H) plays an important role in characterizations of land surface water and heat balance. There are various types of H measurement methods that depend on observation scale, from local-area-scale eddy covariance (EC) to regional-scale large aperture scintillometer (LAS) and remote sensing (RS) products. However, methods of converting one H scale to another to validate RS products are still open for question. A previous area-to-area regression kriging-based scaling method per...

    Cozar et al. (2012) used remotely-sensed data to link phytoplankton growth to the net heat flux in both the northern and southern parts of Lake Victoria. However, the latent and sensible heat fluxes were overestimated by ~26% by assuming a constant air density of 1.3 kg m-3. As a result, the net heat flux was underestimated, bringing into question conclusions regarding the convective circulation.

    Full Text Available The use of scintillometers to determine sensible heat fluxes is now common in studies of land-atmosphere interactions. The main interest in these instruments is due to their ability to quantify energy distributions at the landscape scale, as they can calculate sensible heat flux values over long distances, in contrast to Eddy Correlation systems. However, scintillometer data do not provide a direct measure of sensible heat flux, but require additional data, such as the Bowen ratio (β, to provide flux values. The Bowen ratio can either be measured using Eddy Correlation systems or derived from the energy balance closure. In this work, specific requirements for estimating energy fluxes using a scintillometer were analyzed, as well as the accuracy of two flux calculation methods. We first focused on the classical method (used in standard software. We analysed the impact of the Bowen ratio according to both time averaging and ratio values; for instance, an averaged Bowen ratio (β of less than 1 proved to be a significant source of measurement uncertainty. An alternative method, called the "β-closure method", for which the Bowen ratio measurement is not necessary, was also tested. In this case, it was observed that even for low β values, flux uncertainties were reduced and scintillometer data were well correlated with the Eddy Correlation results.

    Full Text Available In order to better understand tinnitus and distress associated with tinnitus, psychological variables such as emotional and cognitive processing are a central element in theoretical models of this debilitating condition. Interoception, that is, the perception of internal processes, may be such a psychological factor relevant to tinnitus. Against this background, 20 participants suffering from chronic tinnitus and 20 matched healthy controls were tested with questionnaires, assessing interoceptive sensibility, and participated in two tasks, assessing interoceptive accuracy: the Schandry task, a heartbeat estimation assignment, and a skin conductance fluctuations perception task assessing the participants’ ability to perceive phasic increases in sympathetic activation were used. To test stress reactivity, a construct tightly connected to tinnitus onset, we also included a stress induction. No differences between the groups were found for interoceptive accuracy and sensibility. However, the tinnitus group tended to overestimate the occurrence of phasic activation. Loudness of the tinnitus was associated with reduced interoceptive performance under stress. Our results indicate that interoceptive sensibility and accuracy do not play a significant role in tinnitus. However, tinnitus might be associated with a tendency to overestimate physical changes.

  12. Surface layer scintillometry for estimating the sensible heat flux component of the surface energy balance

    Directory of Open Access Journals (Sweden)

    M. J. Savage

    2010-01-01

    Full Text Available The relatively recently developed scintillometry method, with a focus on the dual-beam surface layer scintillometer (SLS, allows boundary layer atmospheric turbulence, surface sensible heat and momentum flux to be estimated in real-time. Much of the previous research using the scintillometer method has involved the large aperture scintillometer method, with only a few studies using the SLS method. The SLS method has been mainly used by agrometeorologists, hydrologists and micrometeorologists for atmospheric stability and surface energy balance studies to obtain estimates of sensible heat from which evaporation estimates representing areas of one hectare or larger are possible. Other applications include the use of the SLS method in obtaining crucial input parameters for atmospheric dispersion and turbulence models. The SLS method relies upon optical scintillation of a horizontal laser beam between transmitter and receiver for a separation distance typically between 50 and 250 m caused by refractive index inhomogeneities in the atmosphere that arise from turbulence fluctuations in air temperature and to a much lesser extent the fluctuations in water vapour pressure. Measurements of SLS beam transmission allow turbulence of the atmosphere to be determined, from which sub-hourly, real-time and in situ path-weighted fluxes of sensible heat and momentum may be calculated by application of the Monin-Obukhov similarity theory. Unlike the eddy covariance (EC method for which corrections for flow distortion and coordinate rotation are applied, no corrections to the SLS measurements, apart from a correction for water vapour pressure, are applied. Also, path-weighted SLS estimates over the propagation path are obtained. The SLS method also offers high temporal measurement resolution and usually greater spatial coverage compared to EC, Bowen ratio energy balance, surface renewal and other sensible heat measurement methods.

    To subsidize its contingency plans for oil leaks, TRANSPETRO, subsidiary of PETROBRAS, set up an internal program with a big extension to obtain Environmental Sensibility Maps over a strip of twenty kilometers of width along more than five thousand kilometers of pipelines. Due to the pioneer characteristic of these natural survey (thematic cartography) it was opted a first approach for integration of this information in 1:50.000 scale. Based on a Geographical Information System (GIS), it was opted the supervised geo processing resources, compiling, firstly, the elevation, soil and geological maps for generation of the physical environment vulnerability units. Using a combination by weight average, ten vulnerability units were generated and were improved through aggregation in five units to decrease the complexity of the representation in map. These classes represent the combinations of variables of the physical environment that can be recognized by theirs corresponding landscapes. Based on interpretation of orbital LANDSAT TM images, aided by verifications in aerial photograph and a systematic survey of notable points of environmental observation (PVAs) along the pipelines, it was elaborated a general map of soil use and vegetable coverage. The classes of this theme were combined with the classes of physical vulnerability environment to generate five classes of Environmental Sensibility (Environmental Sensibility Maps). Over this theme, were attributed the representations of the main types of vegetable coverage and occupation of the soil, as well as the fauna and the other social-economics aspects, obtaining therefore a map with all the essential controller information of the environmental protection measures.

    Fluxes of carbon dioxide, water vapor, and sensible heat obtained over a grassland ecosystem, during the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE), using an aircraft- and two tower-based systems are compared for several days in 1987 and in 1989. The tower-based cospectral estimates of CO2, sensible heat, water vapor, and momentum, expressed as a function of wavenumber K times sampling height z, are relatively similar to the aircraft-based estimates for K x z greater than 0.1. A measurable contribution to the fluxes is observed by tower-based systems at K x z less than 0.01 but not by the aircraft-based system operating at an altitude of approximately 100 m over a 15 x 15 km area. Using all available simultaneous aircraft and tower data, flux estimates by both systems were shown to be highly correlated. As expected from the spatial variations of the greenness index, surface extrapolation of airborne flux estimates tended to lie between those of the two tower sites. The average fluxes obtained, on July 11, 1987, and August 4, 1989, by flying a grid pattern over the FIFE site agreed with the two tower data sets for CO2, but sensible and latent heat were smaller than those obtained by the tower-based systems. However, in general, except for a small underestimation due to the long wavelength contributions and due to flux divergence with height, the differences between the aircraft- and tower-based surface estimates of fluxes appear to be mainly attributable to differences in footprint, that is, differences in the area contributing to the surface flux estimates.

  2. A solar receiver-storage modular cascade based on porous ceramic structures for hybrid sensible/thermochemical solar energy storage

    2016-05-01

    The current state-of-the-art solar heat storage concept in air-operated Solar Tower Power Plants is to store the solar energy provided during on-sun operation as sensible heat in porous solid materials that operate as recuperators during off-sun operation. The technology is operationally simple; however its storage capacity is limited to 1.5 hours. An idea for extending this capacity is to render this storage concept from "purely" sensible to "hybrid" sensible/ thermochemical one, via coating the porous heat exchange modules with oxides of multivalent metals for which their reduction/oxidation reactions are accompanied by significant heat effects, or by manufacturing them entirely of such oxides. In this way solar heat produced during on-sun operation can be used (in addition to sensibly heating the porous solid) to power the endothermic reduction of the oxide from its state with the higher metal valence to that of the lower; the thermal energy can be entirely recovered by the reverse exothermic oxidation reaction (in addition to sensible heat) during off-sun operation. Such sensible and thermochemical storage concepts were tested on a solar-irradiated receiver- heat storage module cascade for the first time. Parametric studies performed so far involved the comparison of three different SiC-based receivers with respect to their capability of supplying solar-heated air at temperatures sufficient for the reduction of the oxides, the effect of air flow rate on the temperatures achieved within the storage module, as well as the comparison of different porous storage media made of cordierite with respect to their sensible storage capacity.

    2013-12-01

    Air-sea exchange processes are typically parameterized in large-scale numerical models owing to the prohibitively large length and time scales involved. For example, intensity predictions of tropical cyclones rely heavily on accurate knowledge of the fluxes of momentum, heat, and moisture from the ocean surface, but these quantities must be computed using bulk flux coefficients since small-scale exchange processes cannot be fully resolved. As a result, these exchange coefficients attempt to represent a large number of physical processes, whose individual roles are difficult to distinguish. One such near-surface process is the formation and transport of sea spray, which has been identified as a possible source of flux modification. In this study, we investigate the role of spray in the turbulent transfer of sensible heat at the air-sea interface using direct numerical simulation (DNS) and a Lagrangian point-particle tracking technique. This is a follow-up to our previous work where the influence of spray on the transfer of momentum was examined. Our idealized simulations suggest that sea spray has the ability to greatly enhance the transfer of sensible heat at the ocean surface, in agreement with existing sea spray models. The physical explanation of this behavior and a discussion of its apparent contradiction with observational studies will be included. Simulation snapshot showing particle-turbulence interaction

    Full Text Available Heat recovery from bottom ash is more important in municipal waste combustion systems than in any other solid fuel combustion since almost 50% of it comprises of non-combustibles. In this study, an ash cooling system using air as the cooling medium has been modeled for pre-heating the combustion air. Air cooling has several advantages over water cooling methods. The study involves modeling using Gambit tool and is solved with the fluent solver. Municipal solid waste incineration systems have the advantage of being located near the waste collection area apart from the high volume reduction ratio. Improvements in the emission control systems and combustion technology can make incineration a highly feasible disposal method. Low furnace temperature due to heat losses through fuel moisture loss and ash sensible heat loss has been a disadvantage with these systems. In this study, a small percentage of the combustion air is pre-heated in a non-contact type heat exchanger and its effect on the available energy of combustion gases at the evaporator outlet is studied. The study is performed for two different waste samples. Results indicate significant increase in available energy at the evaporator outlet and better relative performance for the lower grade fuel. A comparison is made with similar methods reported in the literature along with a brief discussion on the methodologies adopted. The results confirm the importance of installing ash sensible heat recovery mechanism for waste incineration systems as well as the feasibility of the air based method.

    Sensible heat flux greatly influences the Indian monsoon. In this study, we calculated sensible heat flux time-series for 12 sites over the western Tibetan Plateau using Price and Dunne's formula and adjusting the stability function. The time-series were derived from the field observations from the GEWEX Asian Monsoon Experiment (GAME)/Tibet programme under the Global Energy and Water Cycle Experiment (GEWEX). This paper demonstrates that monthly sensible heat fluxes show strong correlations with corresponding precipitation, and that the correlation coefficients increase with precipitation amount. The preceding winter and spring solid precipitation (snowfall and resulting snowpack) can also influence sensible heat flux in May, but the situation is complex. The correlations between heat flux and snowfall at Amdo, Naqu, and Lhasa are negative, but they are positive at Gaize (also known as Gerze) and Dingri. There is a significant relationship between how the variations from the mean calculated heat fluxes at Amdo differ from those at Rikaze, or Dingri, Cuona and Longzi, and their respective June-September precipitation amounts. This phenomenon may result from changes in circulation. When the sensible heat fluxes are above average north of the influence of the Indian monsoon and below average to the south, the summer monsoon circulation develops early and with greater intensity and precipitation, and vice versa.

    Full Text Available La imposibilidad de alcanzar contenidos cognitivos por medio de la percepción sensible actualmente puede ser cuestionada. Se busca reconsiderar que el conocimiento obtenido por medio de la percepción sensible guarde contenidos de objetividad, expresables aún con los conceptos. Se señalan relaciones de correspondencia entre percepción sensible con lo dado y las posibilidades resguardadas en la simbolización. Dado que la conceptualización es la abstracción racional de dichas relaciones, se demuestra la existencia vinculatoria de tales relaciones. El conocimiento de las neuronas espejo confirma la existencia de tales relaciones objetivas de correspondencia. Ello pone en evidencia que el conocimiento tiene acceso parcial a la realidad misma y que tal conocimiento está lejos de una relatividad absoluta.

    Field observations of the atmospheric boundary layer were made over urban and suburban areas in the Yangtze River Delta, China. Sensible heat fluxes were obtained by eddy-covariance (EC) systems and large-aperture scintillometers (LASs). The results indicated that (1) the sensible heat flux obtained by LAS was less noisy and slightly larger than that obtained by EC over both urban and suburban surfaces; (2) the values of were higher when the correlation coefficient of vertical wind speed and temperature () was smaller. Lower values of were due to low-frequency trends. The urban values of were smaller than suburban values at low values; (3) the sensible heat flux determined by LAS was improved by use of the Monin-Obukhov similarity theory of the temperature structure parameter over urban and suburban areas, and the improvement is more significant over urban surface areas.

  10. Minerals sampling: sensibility analysis and correction factors for Pierre Gy's equation

    International Nuclear Information System (INIS)

    Pierre Gy's equation is widely used in ore sampling. This equation is based in four parameters: shape factor, size distribution factor, mineralogical factor and liberation factor. The usual practice is to consider fixed values for the shape and size distribution factors. This practice does not represent well several important ores. The mineralogical factor considers only one specie of interest and the gangue, leaving out other cases such as polymetallic ores where there are more than one species of interest. A sensibility analysis to the Gy's equation factors was done and a procedure to determine specific values for them was developed and presented in this work. mean ore characteristics, associated with an insecure use of the actual procedure, were determined. finally, for a case study, the effects of using each alternative were evaluated.

    The experimental investigation of water cooled electrical arc furnace (EAF) slag used as filler material in the storage tank for sensible heat storage application was demonstrated in this study. The physicochemical and thermal properties of the tested slags were characterized by using X-ray diffraction, scanning electron microcopy, Fourier transform infrared spectroscopy, Raman spectroscopy and laser flash analysis, respectively. In addition, the chemical compatibility between slags and molten nitrate salt (60 wt. % NaNO3 and 40 wt. % KNO3) was investigated at 565 °C for 500 hrs. The obtained results were clearly demonstrated that the slags showed a good corrosion resistance in direct contact with molten salt at elevated temperature. The present study was clearly indicated that a low-cost filler material used in the storage tank can significantly reduce the overall required quantities of the relatively higher cost molten salt and consequently reduce the overall cost of the electricity production.

  13. Sensibility Studies for the Neutral Beam Injection System in TJ-II

    International Nuclear Information System (INIS)

    The sensibility of the Neutral Beam Injection system of TJ-II to the changes of several parameters is analysed. Transmission, absorption and power loads at the intercepting structures are evaluated. The adopted values for the ion source distance, focal length and divergence are confirmed as optimal, showing a small sensitivity to changes, except for the divergence. The operational margins for beam misalignments has been found to be small but feasible, confirming also the reference directions as optimal. Finally four possible alternatives, intended to reduce the power loads at the beam entering structures, are analysed. All of them have been discarded since lead to the appearance of new risk zones, with unacceptable load levels, and reduce the transmitted power. (Author) 13 refs

    2016-03-01

    Experiments were conducted in a natural convection solar greenhouse dryer using different sensible heat storage materials (concrete, sand and rock-bed) in order to study their thermal performance. For both sand and rock-bed, 4″ thickness was found to be optimum as it provides better drying environment both during day and night. The dryer reduced the moisture content of coconuts from 52 (w.b.) to 7 % (w.b.) using concrete as heat storage material in 78 h saving 55 % of drying time compared to open sun drying which takes 174 h for reducing the moisture content to the same level. The sand took 66 h saving 62 % of drying time whereas rock-bed took only 53 h thereby saving 69 % of drying time compared to open sun drying. The efficiency of the dryer was found to be 9.5, 11 and 11.65 % using concrete, sand and rock-bed respectively.

    Equations based on surface renewal (SR) analysis to estimate the sensible heat flux (H) require as input the mean ramp amplitude and period observed in the ramp-like pattern of the air temperature measured at high frequency. A SR-based method to estimate sensible heat flux (HSR-LST) requiring only low-frequency measurements of the air temperature, horizontal mean wind speed, and land-surface temperature as input was derived and tested under unstable conditions over a heterogeneous canopy (olive grove). HSR-LST assumes that the mean ramp amplitude can be inferred from the difference between land-surface temperature and mean air temperature through a linear relationship and that the ramp frequency is related to a wind shear scale characteristic of the canopy flow. The land-surface temperature was retrieved by integrating in situ sensing measures of thermal infrared energy emitted by the surface. The performance of HSR-LST was analyzed against flux tower measurements collected at two heights (close to and well above the canopy top). Crucial parameters involved in HSR-LST, which define the above mentioned linear relationship, were explained using the canopy height and the land surface temperature observed at sunrise and sunset. Although the olive grove can behave as either an isothermal or anisothermal surface, HSR-LST performed close to H measured using the eddy covariance and the Bowen ratio energy balance methods. Root mean square differences between HSR-LST and measured H were of about 55 W m-2. Thus, by using multitemporal thermal acquisitions, HSR-LST appears to bypass inconsistency between land surface temperature and the mean aerodynamic temperature. The one-source bulk transfer formulation for estimating H performed reliable after calibration against the eddy covariance method. After calibration, the latter performed similar to the proposed SR-LST method.

    Full Text Available Abstract Objectives We report a long-term series of nine workers suffering from vibration-induced neuropathy, after many years of exposure to hand-held vibrating tools at high or low frequency. They were treated with temporary selective cutaneous anaesthesia (EMLA® cream of the forearm repeatedly for a period up to one year (in two cases four years. The aim was to improve their capacity to perceive touch and thereby improve hand function and diminish disability. The treatment principle is based on current concepts of brain plasticity, where a deafferentation of a skin area results in improved sensory function in adjacent skin areas. Methods All participants had sensory hand problems in terms of numbness (median touch thresholds > 70 mg and impaired hand function influencing ADL (mean DASH score 22. After an initial identical self-administered treatment period of 8 weeks (12-15 treatments with increasing intervals they did one treatment every 2-3 month. Results After one year sensibility (touch thresholds and tactile discrimination as well as hand function (mean DASH score 13 were improved in a majority of the cases. Seven of the participants choose to continue the treatment after the first year and two of them have continued at a regular basis for up to four years. A surprising, secondary finding was diminishing nocturnal numbness of the hand and arm in eight of the nine subjects from "frequently" to "hardly ever or never". Conclusions Our observations open new perspectives for treatment of impaired sensibility and hand function in a group of patients with vibration induced hand problems where we have no treatment to offer today.

  19. Towards a Postdigital Sensibility: How to get Moved by too Much Music

    Directory of Open Access Journals (Sweden)

    Rasmus Fleischer

    2015-06-01

    Full Text Available The article explores the affective consequences of the new mode of instant access to enormous levels of musical recordings in digital format. It is suggested that this "musical superabundance" might weaken the individuals ability to be affected by music in everyday life, while at the same time leading to a renewed interest in collective experience, in ways which are not limited to established notions of musical "liveness". According to a theory of affect influenced by Spinoza, what is at stake is the capacity of the body to be affected by music. The article proposes that a renegotiated relationship between collective and individual modes of experiencing music can be conceptualized with help of Spinozas distinction between two kinds of affections: actions and passions. After scrutinizing the interface of hardware like Apples Ipod and online services like Spotify, the article proceeds by discussing three musical practices which can all be understood as responses to the superabundance of musical recordings: (1 the ascetic practice of "No Music Day"; (2 the revival of cassette culture; (3 the "bass materialism" associated with the music known as dubstep. While none of these approaches provide any solution to the problem of abundance, they can still be understood as attempts to cultivate a "postdigital sensibility". The article tries to conceptualize the postdigital in a way that transcends the narrower notion of "post-digital aesthetics" that has recently been gaining popularity. Finally, it is argued that such a sensibility has a political significance in its potential to subvert the contemporary processes of commodification.

  4. Persistent unstable atmospheric boundary layer enhances sensible and latent heat loss in a tropical great lake: Lake Tanganyika

    Verburg, Piet; Antenucci, Jason P.

    2010-06-01

    Energy fluxes across the surface of lakes regulate heat storage and affect the water balance. Sensible and latent heat fluxes are affected by atmospheric stability, especially for large lakes. We examined the effect of atmospheric stability on the heat fluxes on seasonal time scales at Lake Tanganyika, East Africa, by estimating hourly sensible and latent heat fluxes and net radiation using thermistor chains and meteorological stations. The atmosphere was almost always unstable, in contrast to the atmosphere above North American Great Lakes which is unstable in winter and stable in summer. Persistent atmospheric instability resulted in a 13% and 18% increase in the annual mean heat loss by latent and sensible heat fluxes, respectively, relative to conditions of neutral stability. The persistent unstable atmosphere is caused by a higher water surface temperature compared with air temperature, which we argue is the case in general in (sub)tropical lakes. Low humidity further enhanced the frequency of unstable conditions and enhanced the exchange of heat and vapor from the lake to the atmosphere. The estimated heat fluxes were sensitive to the temporal scale of data inputs and to the local values of parameters such as air density. To our knowledge this is the first paper that demonstrates and quantifies the effect of atmospheric stability on latent and sensible heat fluxes from a lake on an annual basis, using data collected from the lake surface.

    Recent data demonstrate that the normal sensibility of the hand seems to be age-dependent with the best values in the third decade and a consecutive deterioration afterwards. However, it is not clear if long-term tactile training might prevent this age-dependent decline. We evaluated sensibility of the hand in 125 surgeons aged between 26 and 75 years who perform microsurgical operations, thereby undergoing regular tactile training. We examined sensibility of the radial digital nerve of the index finger (N3) and the ulnar digital nerve of the small finger (N10) using static and moving two-point discrimination (2PD) tests and compared the results to 154 age-matched individuals without specific long-term tactile training. We found significantly lower static and moving 2PD values for the sixth, seventh, and eighth decade of life in the microsurgery group compared to the control group (p < 0.05). This study demonstrates that long-term tactile training might prevent the known age-dependent decline of the sensibility of the hand. PMID:26306813

  8. Measurement of the Sensible Eddy Heat Flux Based on Spatial Averaging of Continuous Ground-Based Observations

    2008-07-01

    Using the standard eddy-covariance (EC) method to quantify mass and energy exchange at a single location usually results in an underestimation of vertical eddy fluxes at the surface. In order to better understand the reasons for this underestimation, an experimental set-up is presented that is based on spatial averaging of air temperature data from a network of ground-based sensors over agricultural land. For eight days during the 34-day observational period in May and June 2007, additional contributions to the sensible heat flux of more than 50Wm-2 were measured in the lower surface layer by applying the spatial EC method as opposed to the standard temporal EC method. Smaller but still significant additional sensible heat fluxes were detected for four more days. The additional energy is probably transported in organised convective structures resulting in a mean vertical wind velocity unequal to zero at the tower location. The results show that convective transport contributes significantly to the surface energy budget for measurement heights as low as 2-3 m. Since these structures may be quasi-stationary, they can hardly be captured by a single-location measurement. The spatial EC set-up presented here is capable of quantifying contributions to the sensible heat flux from structures up to the scale of our spatial sensor network, which covered an area 3.5 × 3.5 km. For future experiments aiming at closing the energy balance, the spatial EC method should be employed to measure both the sensible and latent heat fluxes. Experimental determination of the horizontal advection of sensible and latent heat should also be considered, since such transport must occur due to convergence and divergence related to convection.

  9. Radio-sensibility study of pseudo cereals by means of molecular markers and electronic microscopy

    International Nuclear Information System (INIS)

    With the purpose of observing the radio sensibility in two species of pseudo cereals group (Amaranthus hypochondria cus and Chenopodium berlandieri subsp. nuttalliae), germplasm of 4 amaranth genotypes was irradiated (A-21-0-10, Mixquic-09, M-2 and M-6) and 4 huauzontle genotypes (H-18, H-19, H-10 and red Chia) in the Gamma Irradiator of the ININ in a dose range of 50 to 500 Gy with intervals each 50 Gy and a treatment witness without irradiating. The evaluation of the material was carried out in three stages: 1) the pheno logy and morphology was evaluated during the plants development in each treatment under greenhouse conditions; 2) the radio sensibility was evaluated at molecular level by means of molecular markers type Ssr (Simple Sequence Repeats); and 3) the irradiated seeds were analyzed by under vacuum electronic microscopy. According to the results, the pheno logy phases were ahead in lower doses to 250 Gy for amaranth and higher doses to 150 Gy for huauzontle, there being a morphological variation in leaves and cob. The morphological variables were favored in dose from 50 to 200 Gy for amaranth, while in huauzontle the morphology presented more response variation to the radiation. In the DNA, the 21 Ssr were 100% polymorphic in amaranth and 97% polymorphic in huauzontle, being one of the more polymorphic the QCA0005 in amaranth and QCA0005 in huauzontle. The generated dendrograms showed greater similarity between Mixquic-09 and M-2 (amaranth) and between H-19 and H-10 (huauzontle). While by treatments, in amaranth the dose of 500 Gy presented most polymorphic difference and in huauzontle was the dose of 200 Gy. The under vacuum electronic microscopy did not show differences in the seed structure while the elemental analysis showed the presence of carbon, oxygen, aluminum, sulfur and calcium as the most common elements and in more concentration carbon and oxygen. For A. hypochondria cus the dose DL50 (median lethal dose) was between 50 and 100 Gy and for C

    The large source of uncertainty in satellite-based evapotranspiration algorithm results from the estimation of sensible heat flux H. Traditionally eddy covariance sensors, and recently large-aperture scintillometers, have been used as ground truth to evaluate satellite-based H estimates. The two methods rely on different physical measurement principles, and represent different foot print sizes. In New Mexico, we conducted a field campaign during summer 2008 to compare H estimates obtained from the eddy covariance and scintillometer methods. During this field campaign, we installed sonic anemometers; one propeller eddy covariance (OPEC) equipped with net radiometer and soil heat flux sensors; large aperture scintillometer (LAS); and weather station consisting of wind speed, direction and radiation sensors over three different experimental areas consisting of different roughness conditions (desert, irrigated area and lake). Our results show the similarities and differences in H estimates obtained from these various methods over the different land surface conditions. Further, our results show that the H estimates obtained from the LAS agree with those obtained from the eddy covariance method when high frequency thermocouple temperature, instead of the typical weather station temperature measurements, is used in the LAS analysis.

  12. Construction and characterization of a hollow cathode tube for high sensibility laser spectroscopy

    International Nuclear Information System (INIS)

    A new hollow cathode tube argon-iron design was developed to be used in laser atomic spectroscopy experiments, were high sensibility is required. This tube was employed in order to allow laser absorption and optogalvanic signal measurements. The tube also included fused-quartz Brewster angle windows aligned with the optical axis in each ending of the tube. Therefore, in this configuration a minimum laser intensity losses through the windows can be attained for the appropriate light polarization. The optogalvanic signal detection was accomplished using a tunable dye laser resonant with the Ar, 3p5 4p (3S1)--> 3p5 4d (3D10) transition, that corresponds to 591.2 nm in air. It was also possible to determine the gas temperature by measuring the Doppler line broadening and the results were compared to those obtained from a theoretical model for gas heat conduction. To measure the temperature of the cathode external surface a thermocouple was used inside the tube. The analysis of results showed that a high signal to noise ratio can be obtained with this tube configuration, that permits experimental investigation of electronic transitions presenting low light absorption cross sections.

    Due to water management issues, operating conditions need to be carefully chosen in order to properly operate fuel cells. Because of the gas consumption along the feeding channels and water production at the cathode, internal cell humidification is highly inhomogeneous. Consequently, operating fuel cells are very often close to critical operating conditions, such as flooding and drying, at least locally. Based on this observation, the critical current, corresponding to internal cell humidification balance (acurate membrane hydration, without excess of water at the electrodes), is deduced from a pseudo-2D model of mass transfer in the cell. Using the model, a parametric sensibility study of the operating conditions is presented to analyze the cell internal humidification. Dead-end and flow-through modes of hydrogen supply are also compared. It is shown that the operating temperature is a key parameter to manage the cell humidification. Moreover, although the oxygen stoichiometric ratio has an effect on cell humidification, this influence is limited and cannot be used alone to adjust the cell humidification. Furthermore, it is shown that in some cases, humidifying the anode inlet gas is of little interest to the internal humidification adjustment. Finally, those results allow to understand the role that each operating parameter can play on the cell internal humidification. Consequently, this study is of a great interest to water management improvement in polymer electrolyte membrane fuel cells.

  15. Scaling Flux Tower Observations of Sensible Heat Flux Using Weighted Area-to-Area Regression Kriging

    Full Text Available Sensible heat flux (H plays an important role in characterizations of land surface water and heat balance. There are various types of H measurement methods that depend on observation scale, from local-area-scale eddy covariance (EC to regional-scale large aperture scintillometer (LAS and remote sensing (RS products. However, methods of converting one H scale to another to validate RS products are still open for question. A previous area-to-area regression kriging-based scaling method performed well in converting EC-scale H to LAS-scale H. However, the method does not consider the path-weighting function in the EC- to LAS-scale kriging with the regression residue, which inevitably brought about a bias estimation. In this study, a weighted area-to-area regression kriging (WATA RK model is proposed to convert EC-scale H to LAS-scale H. It involves path-weighting functions of EC and LAS source areas in both regression and area kriging stages. Results show that WATA RK outperforms traditional methods in most cases, improving estimation accuracy. The method is considered to provide an efficient validation of RS H flux products.

  17. Conversation, characterisation and corpus linguistics: Dialogue in Jane Austen’s Sense and Sensibility

    Full Text Available This article reports on a corpus-based exploration of the role that fictional dialogue plays in characterisation. The focus is on the two main characters of Austen’s Sense and Sensibility and (a the extent to which certain features of their dialogue can be said to tie in with general perceptions that Elinor represents the “sense” and Marianne the “sensibility” of the novel’s title; and (b the extent to which Austen can be said to have exploited these features to enable the sisters to speak with subtly differing voices. The features themselves were drawn from two linguistic frameworks, namely cohesion in text linguistics (specifically, the category of conjunctive cohesion as originated by Halliday and Hasan (1976, and the category of “involvement” in register analysis (most prominently, Biber 1988. The density of these features in each dialogue was calculated, compared statistically and salient differences considered in relation to the focal issues of the study. Although two of the five hypotheses formulated were not supported, the results overall provided strong indications that Austen successfully distinguishes between the sisters through their dialogue, and often in ways that link with less subtle, more explicit cues to their character that are given in the text. The study thus reveals how certain text-linguistic and register features can underpin characterisation in fiction, and in so doing explicates aspects of what it is that readers and literary critics respond to when they comment on characterisation in a novel.

  18. Determination of sensible heat flux over sparse canopy using thermal infrared data

    International Nuclear Information System (INIS)

    Surface temperatures, Ts, were estimated for a natural vegetative surface in Owens Valley, California, with infrared thermometric observations collected from an aircraft. The region is quite arid and is composed primarily of bushes (∼30%) and bare soil (∼70%). Application of the bulk transfer equation for the estimation of sensible heat, H, gave unsatisfactory values when compared to Bowen ratio and eddy correlation methods over a particular site. This was attributed to the inability with existing data to properly evaluate the resistance to heat transfer, rah. To obtain appropriate rah-values the added resistance to heat transfer, kB−1, was allowed to vary although there is both theoretical and experimental evidence that kB−1 for vegetative surfaces can be treated as constant. The present data indicate that for partial canopy cover under arid conditions kB−1 may be a function of Ts measured radiometrically. The equation determining kB−1 was simplified and tested over another arid site with good results; however, this had a limited data set (i.e., 6 data points). The dimensionless kB−1 equation is simplified for use over full canopy cover and is shown to give satisfactory estimates of H over a fully-grown wheat crop

These standards don't specify how a home must be built, but instead set levels for the efficient use of electricity in the home. The unique designs of these homes prove that energy-efficient homes can look good, too. A profile is given for each home. Comments from energy specialists and, in most cases, the owners are included. Information is provided on the features of the homes and how well they work. A glossary of technical terms is listed in the back of the book.

  20. On the Potential Impact of Daytime Surface Sensible Heat Flux on the Dissipation of Martian Cold Air Outbreaks

    The Martian daytime soil surface temperature is governed primarily by the net irradiance balance and surface soil heat flux. Thus the outbreak of a cold air mass generates increased sensible heat flux that is conducive to daytime dissipation of the cold air mass thermal characteristics. Conceptual and scaling evaluations of this dissipation are provided while comparison is made with similar situations on Earth. It is estimated that sensible heat flux contribution to the dissipation of the original thermal structure of the cold air could be three times larger than the corresponding situation on Earth. Illustrative numerical model simulations provide scaling of the potential impact on the dissipation of cold air masses for various combinations of background wind speed and latitudes.

  1. Sensible biological models to be exposed to VDT (Video Display Terminal) radiations in human male reproduction

    International Nuclear Information System (INIS)

    Temperature and environmental effects, particularly endocrine disrupters and EMF radiations, are actively investigated in human and non-human reproduction experimental models. Sensitivity and specificity of the different cell types of the testes seminiferous tubules in animals and in human are evaluated, showing a specific responsiveness of spermatogonia (SPG) and resting pachytene spermatocytes (SPC). At 32 oC the 24 h short-term cultures of biopsies of normal human testis show an expected low occurrence of apoptotic SPG (1 %) that increases to 3,4 % in peer samples exposed to VDT for the same period, with the appearance of apoptotic SPC (4,6 %). In samples from a thermically-impaired testis of the same subject the apoptotic occurrence of SPG is 2,6 % with 15,4 % for SPC after 24 h cultures. After 24 h exposure to VDT the apoptotic score is 7,6 % for SPG and 18,5 % for SPC in thermically impaired peer samples. With EMF-bioshields the apoptotic score for SPG is 0,8 % in normal 2,2 % for SPG and 13,8 % for SPC in T-impaired peer-samples. NMRS of the cultures fluids show a proportional production of lactate, corresponding to the different degrees of histopathological impairment of the samples. IVOS (Integrated Visual Optic System) analysis of sperm samples from thermically-impaired, not-repaired and repaired testes exposed to VDT shows sensible variations on straightness (STR), linearity (LIN) and lateral head displacement (LHD) parameters. To evaluate the thermic and non-thermic potential bioeffects of VDT on human spermatogenesis the specificity, the sensitivity and the reproducibility of the biological models on one side and the specificity of the methodologies on the other side must be provided.

    Hyppoenen, M.; Walden, J.A.

    1996-12-31

    The design, construction and measurements of a computer controlled system applicable to flux measurements of a scalar quantity by the gradient technique are described. Accuracy requirements for the measured variables which are used for flux calculations are considered, together with some practical aspects concerning data storage and control. The construction includes the hardware and the data acquisition, sample intake, and temperature measurement systems. The measurements comprise laboratory tests of the temperature probes and the hardware as well as field tests over wheat and grass land for temperature and wind speed and ozone (O{sub 3}), carbon dioxide (CO{sub 2}) and nitrous oxide (N{sub 2}O) concentration profiles. The hardware takes care of most of the operation and only the necessary part is done by the software. The data acquisition system is flexible, accepting the input of either digital and/or analog signals. It also controls the whole system, storing all the data in a single data file. The sample intake unit is designed to take continuous samples in to the monitors as well as grab samples into the canisters. Samples can be selected from one to four levels with no dead volumes in the sampling tubes. The temperature measurement system is constructed using a pair of temperature probes, Pt-100, which are connected to the same signal processing card, in order to remove the offset of the electronic components as well as the bias associated with single probes. This ensures the accuracy of the probes down to 0.005 deg C. According to the field measurements, the relative error limits for the sensible heat fluxes varied from 7 to 20 % in an unstable atmospheric situation. For the ozone flux, the error limits varied from 20 to 100 %, indicating a much poorer accuracy of the monitor compared to the temperature probes. (orig.) 16 refs.

  3. Sensibility analysis of VORIS lava-flow simulations: application to Nyamulagira volcano, Democratic Republic of Congo

    Full Text Available Assessment and management of volcanic risk are important scientific, economic, and political issues, especially in densely populated areas threatened by volcanoes. The Virunga area in the Democratic Republic of Congo, with over 1 million inhabitants, has to cope permanently with the threat posed by the active Nyamulagira and Nyiragongo volcanoes. During the past century, Nyamulagira erupted at intervals of 1–4 years – mostly in the form of lava flows – at least 30 times. Its summit and flank eruptions lasted for periods of a few days up to more than two years, and produced lava flows sometimes reaching distances of over 20 km from the volcano, thereby affecting very large areas and having a serious impact on the region of Virunga. In order to identify a useful tool for lava flow hazard assessment at the Goma Volcano Observatory (GVO, we tested VORIS 2.0.1 (Felpeto et al., 2007, a freely available software (http://www.gvb-csic.es based on a probabilistic model that considers topography as the main parameter controlling lava flow propagation. We tested different Digital Elevation Models (DEM – SRTM1, SRTM3, and ASTER GDEM – to analyze the sensibility of the input parameters of VORIS 2.0.1 in simulation of recent historical lava-flow for which the pre-eruption topography is known. The results obtained show that VORIS 2.0.1 is a quick, easy-to-use tool for simulating lava-flow eruptions and replicates to a high degree of accuracy the eruptions tested. In practice, these results will be used by GVO to calibrate VORIS model for lava flow path forecasting during new eruptions, hence contributing to a better volcanic crisis management.

  4. Neglect of the foreign invisible: Historiography and the navigation of conflicting sensibilities.

    Burman, Jeremy Trevelyan

    2015-05-01

    This essay is intended first as a contribution to historiography, and only second as a contribution to the history of developmental psychology. It is therefore a discussion--primarily--of the doing of the history of psychology, rather than of its content. Briefly put: American psychology, including its associated approaches to the history of psychology, is not adequately equipped to benefit fully from the contributions of foreign scholars. To make the resulting argument clear, two archive-driven microhistories are reviewed, contrasted, augmented with new archival research, and synthesized: Yeh Hsueh's (2004) examination of the nomination process at Harvard University that led to the awarding of an honorary doctorate to Jean Piaget in 1936, and Marc Ratcliff and Paloma Borella's (2013) examination-just recently published in French-of a similar process that resulted in Piaget's hiring at Geneva in 1929 and his eventual promotion in 1940. Comparing the authors' different approaches to similar content then affords this article's larger argument: we need to broaden our sensibilities so we can see high-quality foreign contributions for what they are. Several interesting insights result if we do. Among them: although Piaget's theory is today mistakenly criticized for being asocial, and this serves as justification for countering his early works with Vygotsky's posthumous critique, it emerges from these archival studies that Piaget may have in fact chosen to present himself and his work as nonsociological (when this was not the case) for reasons unrelated to his intellectual project. Such examples then broaden the discussion of "neglect of the foreign invisible" to include suppression--even censorship (by self or other)--which in turn reflects the primary problem afforded by internationalization: by what standards are we to judge the contributions of "foreigners" into "our" discipline?

  5. Technical approach to finalizing sensible soil cleanup levels at the Fernald Environmental Management Project

    International Nuclear Information System (INIS)

    The remedial strategy for addressing contaminated environmental media was recently finalized for the US Department of Energy's (DOE) Fernald Environmental Management Project (FEMP) following almost 10 years of detailed technical analysis. The FEMP represents one of the first major nuclear facilities to successfully complete the Remedial Investigation/Feasibility Study (RI/FS) phase of the environmental restoration process. A critical element of this success was the establishment of sensible cleanup levels for contaminated soil and groundwater both on and off the FEMP property. These cleanup levels were derived based upon a strict application of Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) regulations and guidance, coupled with positive input from the regulatory agencies and the local community regarding projected future land uses for the site. The approach for establishing the cleanup levels was based upon a Feasibility Study (FS) strategy that examined a bounding range of viable future land uses for the site. Within each land use, the cost and technical implications of a range of health-protective cleanup levels for the environmental media were analyzed. Technical considerations in driving these cleanup levels included: direct exposure routes to viable human receptors; cross- media impacts to air, surface water, and groundwater; technical practicality of attaining the levels; volume of affected media; impact to sensitive environmental receptors or ecosystems; and cost. This paper will discuss the technical approach used to support the finalization of the cleanup levels for the site. The final cleanup levels provide the last remaining significant piece to the puzzle of establishing a final site-wide remedial strategy for the FEMP, and positions the facility for the expedient completion of site-wide remedial activities

  6. Sense and Sensibility: The Case for the Nationwide Inclusion of Engineering in the K-12 Curriculum

    The competitive status of the United States is inextricably linked to innovation just as innovation is inseparable from science, technology, engineering, and mathematics. To stay competitive in innovation requires that the United States produce a 21st century workforce complete with requisite education, training, skills, and motivation. If we accept a priori that science, technology, engineering, and mathematics education are crucial to competitiveness and innovation and that, in terms of innovation, mathematics, science, and engineering are interdependent, why are mathematics and science uniformly ubiquitous in the K-12 curriculum while engineering is conspicuously absent? We are passionate in our belief that the uniform addition of engineering to the K-12 curriculum will help ensure that the nation has "the right" 21st Century workforce. Furthermore, we believe that a nationwide effort, led by a coalition of engineering academics, practitioners, and societies is required to turn this goal into reality. However, accomplishing this goal necessitates, as we are reminded by the title of Jane Austen's timeless novel, "Sense and Sensibility", a workable solution that seeks the "middle ground" between passion and reason. We begin our paper by making two essential points: Engineers are not scientists. Engineering exists separate from science, has its own specialized knowledge community apart from science, and it is largely responsible for many of the most significant advancements and improvements in the quality of our life. Our workable solution requires that K-12 education, nationwide, accommodate the inclusion of engineering as a stand alone curriculum and we offer three reasons to support our position: (1) workforce development, (2) stimulating interest in STEM (science, technology, engineering, and mathematics) courses and careers, and (3) creating a technologically literate society. We conclude with some thoughts on how this important goal can be accomplished.

Por tal motivo, en este ensayo, a partir de la reflexión hermenéutica se aspira resignificar la academia, proponiendo las experiencias y vivencias compartidas para la construcción de saberes comuniversitarios que respondan a los imperativos del clima cultural del presente. Se concluye que la experiencia como vivencia y su narrativa confiere a la academia nuevas metáforas éticas y estéticas de autovaloración y valoración del otro. De allí, la invitación a viajar por las sendas de lo vivido, donde la creatividad permita la metamorfosis y proyección hacia una universidad sensible. Corresponde, pues, proyectar a la universidad como ser pensante, reflexiva, facultada para construir y deconstruir su cultura, productora de saberes, en la medida en que convive en sociedad.

  14. Characterization of Turbulent Latent and Sensible Heat Flux Exchange Between the Atmosphere and Ocean in MERRA

    Turbulent fluxes of heat and moisture across the atmosphere-ocean interface are fundamental components of the Earth s energy and water balance. Characterizing both the spatiotemporal variability and the fidelity of these exchanges of heat and moisture is critical to understanding the global water and energy cycle variations, quantifying atmosphere-ocean feedbacks, and improving model predictability. This study examines the veracity of the recently completed NASA Modern-Era Retrospective analysis for Research and Applications (MERRA) product with respect to its representation of the surface turbulent heat fluxes. A validation of MERRA turbulent heat fluxes and near-surface bulk variables at local, high-resolution space and time scales is achieved by making comparisons to a large suite of direct observations. Both in situ and satellite-observed gridded surface heat flux estimates are employed to investigate the spatial and temporal variability of the surface fluxes with respect to their annual mean climatologies, their seasonal covariability of near-surface bulk parameters, and their representation of extremes. The impact of data assimilation on the near-surface parameters is assessed through evaluation of incremental analysis update tendencies produced by the assimilation procedure. It is found that MERRA turbulent surface heat fluxes are relatively accurate for typical conditions but have systematically weak vertical gradients in moisture and temperature and have a weaker covariability between the near-surface gradients and wind speed than found in observations. This results in an underestimate of the surface latent and sensible heat fluxes over the western boundary current and storm track regions. The assimilation of observations mostly acts to bring MERRA closer to observational products by increasing moisture and temperature near the surface and decreasing the near-surface wind speeds. The major patterns of spatial and temporal variability of the turbulent heat

  15. Using sonic anemometer temperature to measure sensible heat flux in strong winds

    Directory of Open Access Journals (Sweden)

    S. P. Burns

    2012-09-01

    Full Text Available Sonic anemometers simultaneously measure the turbulent fluctuations of vertical wind (w' and sonic temperature (Ts', and are commonly used to measure sensible heat flux (H. Our study examines 30-min heat fluxes measured with a Campbell Scientific CSAT3 sonic anemometer above a subalpine forest. We compared H calculated with Ts to H calculated with a co-located thermocouple and found that, for horizontal wind speed (U less than 8 m s−1, the agreement was around ±30 W m−2. However, for U ≈ 8 m s−1, the CSAT H had a generally positive deviation from H calculated with the thermocouple, reaching a maximum difference of ≈250 W m−2 at U ≈ 18 m s−1. With version 4 of the CSAT firmware, we found significant underestimation of the speed of sound and thus Ts in high winds (due to a delayed detection of the sonic pulse, which resulted in the large CSAT heat flux errors. Although this Ts error is qualitatively similar to the well-known fundamental correction for the crosswind component, it is quantitatively different and directly related to the firmware estimation of the pulse arrival time. For a CSAT running version 3 of the firmware, there does not appear to be a significant underestimation of Ts; however, a Ts error similar to that of version 4 may occur if the CSAT is sufficiently out of calibration. An empirical correction to the CSAT heat flux that is consistent with our conceptual understanding of the Ts error is presented. Within a broader context, the surface energy balance is used to evaluate the heat flux measurements, and the usefulness of side-by-side instrument comparisons is discussed.

    The French agricultural economy is closely connected with weather-climatic conditions. For example, dryness caused by the heat-wave of 2003 seriously affected the vegetation leading to a significant slowdown of photosynthetic activity. This resulted in logical decrease of agricultural production, in particular for arable lands and fodders. The Global warming that has begun at the end of the 19th century and seems to continue and even intensify during the 21st century (GIEC, 2007) arises a question of farming system sensibility when faced with Climate Change in the future. In France, recent studies (Cloppet and al, 2009) have conducted to the probable climate features spatialization on the national territory according to different scenarios. Whatever the scenario considered, it seems that the present Norman climate type is going to disappear by the end of century to be supplanted by a type of weather influenced by raising evapotranspiration, minimal and maximum temperatures as well as a raising speed of wind and solar radiation. Globally, this could emphasize agriculture soil dryness negative impact on large cereal land and pastures production (Butault, 2009, Ruget & Brisson, 2007). However, this climatic evolution could bring some production gain when the available water content of soils allows preventing or strongly limiting the hydrous stress emergence. For the current period and horizon 2100, according to the scenario A1B of the GIEC, the evaluation and the mapping with fine spatial resolution of this pedo-climatic indicator present a capital stake to appreciate the sensitivity of the agriculture of the Normandy in connection with the climatic evolution announced for the end of the 21st century. This exploratory work has been undertaken for the departmental territory of Calvados (5500 km²). For that purpose, it has been necessary beforehand to work out a precise mapping of soils on the basis of 7514 soil boreholes. The treatment of the soil database has allowed

    In single column and large-eddy simulation studies of the atmospheric boundary layer, surface sensible heat flux is often used as a boundary condition. In this paper, we delineate the fundamental shortcomings of such a boundary condition in the context of stable boundary layer modelling and simulation. Using an analytical approach, we are able to show that for reliable model results of the stable boundary layer accurate surface temperature prescription or prediction is needed. As such, the use of surface heat flux as a boundary condition should be avoided in stable conditions.

    Full Text Available Abstract Background The present study was undertaken in order to determine whether a set of clinical features, which are not included in the DSM-IV or ICD-10 for Asperger Syndrome (AS, are associated with AS in particular or whether they are merely a familial trait that is not related to the diagnosis. Methods Ten large families, a total of 138 persons, of whom 58 individuals fulfilled the diagnostic criteria for AS and another 56 did not to fulfill these criteria, were studied using a structured interview focusing on the possible presence of face recognition difficulties, aberrant sensibility and eating habits and sleeping disturbances. Results The prevalence for face recognition difficulties was 46.6% in individuals with AS compared with 10.7% in the control group. The corresponding figures for subjectively reported presence of aberrant sensibilities were 91.4% and 46.6%, for sleeping disturbances 48.3% and 23.2% and for aberrant eating habits 60.3% and 14.3%, respectively. Conclusion An aberrant processing of sensory information appears to be a common feature in AS. The impact of these and other clinical features that are not incorporated in the ICD-10 and DSM-IV on our understanding of AS may hitherto have been underestimated. These associated clinical traits may well be reflected by the behavioural characteristics of these individuals.

  4. Differences in atmospheric convection caused by waste energy rejected in the forms of sensible and latent heats

    International Nuclear Information System (INIS)

    Results of this study indicate that atmospheric effects, such as the initiation or triggering of cumulus clouds, caused by cooling towers would be dependent on the size and gradient of the density perturbation created by the emissions contained in the tower plume. The size and gradient can be minimized if latent heat rather than sensible heat is rejected by the towers. Latent heat releases can be realized as sensible heat if the latent heat plume condenses, but if this occurs downwind of the tower after mixing with the environment has occurred, the density gradient will be reduced, and this should reduce overall effects. Thus, while dry towers would eliminate shadowing and drift (category II effects) that commonly occur at wet cooling tower sites, their use would increase the likelihood of atmospheric effects in the form of convective cloud initiation and associated effects such as rain anomalies. A cooling system rejecting solely latent heat might be ideal to minimize atmospheric effects (particularly if the plume could be made subsaturated), but such a device is not available to industry. A cooling pond may be a close substitute

  5. Estimating sensible heat flux in agricultural screenhouses by the flux-variance and half-order time derivative methods

    2016-04-01

    Previous studies have established that the eddy covariance (EC) technique is reliable for whole canopy flux measurements in agricultural crops covered by porous screens, i.e., screenhouses. Nevertheless, the eddy covariance technique remains difficult to apply in the farm due to costs, operational complexity, and post-processing of data - thereby inviting alternative techniques to be developed. The subject of this research was estimating the sensible heat flux by two turbulent transport techniques, namely, Flux-Variance (FV) and Half-order Time Derivative (HTD) whose instrumentation needs and operational demands are not as elaborate as the EC. The FV is based on the standard deviation of high frequency temperature measurements and a similarity constant CT. The HTD method requires mean air temperature and air velocity data. Measurements were carried out in two types of screenhouses: (i) a banana plantation in a light shading (8%) screenhouse; (ii) a pepper crop in a dense insect-proof (50-mesh) screenhouse. In each screenhouse an EC system was deployed for reference and high frequency air temperature measurements were conducted using miniature thermocouples installed at several levels to identify the optimal measurement height. Quality control analysis showed that turbulence development and flow stationarity conditions in the two structures were suitable for flux measurements by the EC technique. Energy balance closure slopes in the two screenhouses were larger than 0.71, in agreement with results for open fields. Regressions between sensible heat flux measured by EC and estimated by FV resulted with CT values that were usually larger than 1, the typical value for open field. In both shading and insect-proof screenhouses the CT value generally increased with height. The optimal measurement height, defined as the height with maximum R2 of the regression between EC and FV sensible heat fluxes, was just above the screen. CT value at optimal height was 2.64 and 1.52 for

    The Tibetan Plateau (TP) has become a focus of strong scientific interest due to its role in the global water cycle and its reaction to climate change. Regional flux estimates of sensible and latent heat are important variables for linking the energy and hydrological cycles at the TP's surface. Within this framework, a 3-year dataset (2008-2010) of eddy covariance measured turbulent fluxes was compiled from four stations on the TP into a standardised workflow: corrections and quality tests were applied using an internationally comparable software package. Second, the energy balance closure ( C EB) was determined and two different closure corrections applied. The four stations (Qomolangma, Linzhi, NamCo and Nagqu) represent different locations and typical land surface types on the TP (high altitude alpine steppe with sparse vegetation, a densely vegetated alpine meadow, and bare soil/gravel, respectively). We show that the C EB differs between each surface and undergoes seasonal changes. Typical differences in the turbulent energy fluxes occur between the stations at Qomolangma, Linzhi and NamCo, while Nagqu is quite similar to NamCo. Specific investigation of the pre-monsoon, the Tibetan Plateau summer monsoon, post-monsoon and winter periods within the annual cycle reinforces these findings. The energy flux of the four sites is clearly influenced by the Tibetan Plateau monsoon. In the pre-monsoon period, sensible heat flux is the major energy source delivering heat to the atmosphere, whereas latent heat flux is greater than sensible heat flux during the monsoon season. Other factors affecting surface energy flux are topography and location. Land cover type also affects surface energy flux. The energy balance residuum indicates a typically observed overall non-closure in winter, while closure (or `turbulent over-closure') is achieved during the Tibetan Plateau summer monsoon at the Nagqu site. The latter seems to depend on ground heat flux, which is higher in the

    Full Text Available The delay produced by drug, in the process of cercaria-schistosomulum transformation, was used to verify the sensibility of different larval stages to the host cell immune responses, in vivo. The peritoneal cavity of mice, a model used for in vivo observations, was choiced for the experiments. As well characterized schistosomules, cercariae and larvae in the process of transformation were coated and arrested by host cells, and could not be recovered by simple saline washings. After 10-²M EDTA saline washings, they were released alive, with good vitality and movements. Thus, different kind of larvae in the process of adaptation of the cercaria to the host are strongly coated by immune cells, but these fail to kill the invading organisms, at least during a few hours after invasion.

  12. Wavelet and Fractal Analysis of Remotely Sensed Surface Temperature with Applications to Estimation of Surface Sensible Heat Flux Density

    2000-01-01

    Wavelet and fractal analyses have been used successfully to analyze one-dimensional data sets such as time series of financial, physical, and biological parameters. These techniques have been applied to two-dimensional problems in some instances, including the analysis of remote sensing imagery. In this respect, these techniques have not been widely used by the remote sensing community, and their overall capabilities as analytical tools for use on satellite and aircraft data sets is not well known. Wavelet and fractal analyses have the potential to provide fresh insight into the characterization of surface properties such as temperature and emissivity distributions, and surface processes such as the heat and water vapor exchange between the surface and the lower atmosphere. In particular, the variation of sensible heat flux density as a function of the change In scale of surface properties Is difficult to estimate, but - in general - wavelets and fractals have proved useful in determining the way a parameter varies with changes in scale. We present the results of a limited study on the relationship between spatial variations in surface temperature distribution and sensible heat flux distribution as determined by separate wavelet and fractal analyses. We analyzed aircraft imagery obtained in the thermal infrared (IR) bands from the multispectral TIMS and hyperspectral MASTER airborne sensors. The thermal IR data allows us to estimate the surface kinetic temperature distribution for a number of sites in the Midwestern and Southwestern United States (viz., San Pedro River Basin, Arizona; El Reno, Oklahoma; Jornada, New Mexico). The ground spatial resolution of the aircraft data varied from 5 to 15 meters. All sites were instrumented with meteorological and hydrological equipment including surface layer flux measuring stations such as Bowen Ratio systems and sonic anemometers. The ground and aircraft data sets provided the inputs for the wavelet and fractal analyses

    Full Text Available This paper undertook the damage valuation of cement production induced air pollution on rural farming livelihood, assessed the impact on farmers’ profitability as well as investigating the corporate social responsibility investment of the cement companies in the producing host communities in Nigeria. It then examined how legislation and enforcement can be made to strike a sensible balance between the environmental damage enabled by cement pollution and ensuring a sustainable farming livelihood. A two stage simple random sampling procedure was adopted for the paper to select a total of 120 respondentsin the target and control areas. Data were analyzed using descriptive statistics, Dichotomous–Choice Contingent Valuation Method (DC- CVM that terminated into the logit model and the budgetary analysis. The total Willingness-To-Pay (WTP/annum to avert the negative externalities on the host communities’ farming livelihood was N3.21 billion. The profitability in farming in the target cement producing area with respect to thenet farm income and the rate of return to capital investment were lower in the target as compared to the control area. The Corporate Social Responsibility (CSR investments ofthe cement producing companies were small compared to the profits realized by them. The proportions of the CSR investments with respect to the company’s profits were between 0.4% and 1.6% for the five years considered in the paper. Efforts have been made by the government to enact laws, regulations and standards to ensureenvironmentally sound and sustainable environment though the institution initially put in place to implement them was not given legal powers of enforcement. Things are however changing with the establishment of another with such powers. It is only by such proper implementation, a sensible balance can be struck between uncontrolled cement dust pollution associated with excess profits to the cement producers and sustainable

  14. A Bayesian analysis of sensible heat flux estimation: Quantifying uncertainty in meteorological forcing to improve model prediction

    KAUST Repository

    Ershadi, Ali

    2013-05-01

    The influence of uncertainty in land surface temperature, air temperature, and wind speed on the estimation of sensible heat flux is analyzed using a Bayesian inference technique applied to the Surface Energy Balance System (SEBS) model. The Bayesian approach allows for an explicit quantification of the uncertainties in input variables: a source of error generally ignored in surface heat flux estimation. An application using field measurements from the Soil Moisture Experiment 2002 is presented. The spatial variability of selected input meteorological variables in a multitower site is used to formulate the prior estimates for the sampling uncertainties, and the likelihood function is formulated assuming Gaussian errors in the SEBS model. Land surface temperature, air temperature, and wind speed were estimated by sampling their posterior distribution using a Markov chain Monte Carlo algorithm. Results verify that Bayesian-inferred air temperature and wind speed were generally consistent with those observed at the towers, suggesting that local observations of these variables were spatially representative. Uncertainties in the land surface temperature appear to have the strongest effect on the estimated sensible heat flux, with Bayesian-inferred values differing by up to ±5°C from the observed data. These differences suggest that the footprint of the in situ measured land surface temperature is not representative of the larger-scale variability. As such, these measurements should be used with caution in the calculation of surface heat fluxes and highlight the importance of capturing the spatial variability in the land surface temperature: particularly, for remote sensing retrieval algorithms that use this variable for flux estimation.

  15. A method for sensible heat flux model parameterization based on radiometric surface temperature and environmental factors without involving the parameter KB-1

    Zhuang, Qifeng; Wu, Bingfang; Yan, Nana; Zhu, Weiwei; Xing, Qiang

    2016-05-01

    Sensible heat flux is a key component of land-atmosphere interaction. In most parameterizations it is calculated with surface-air temperature differences and total aerodynamic resistance to heat transfer (Rae) that is related to the KB-1 parameter. Suitable values are hard to obtain since KB-1 is related both to canopy characteristics and environmental conditions. In this paper, a parameterize method for sensible heat flux over vegetated surfaces (maize field and grass land in the Heihe river basin of northwest China) was proposed based on the radiometric surface temperature, surface resistance (Rs) and vapor pressures (saturated and actual) at the surface and the atmosphere above the canopy. A biophysics-based surface resistance model was revised to compute surface resistance with several environmental factors. The total aerodynamic resistance to heat transfer is directly calculated by combining the biophysics-based surface resistance and vapor pressures. One merit of this method is that the calculation of KB-1 can be avoided. The method provides a new way to estimate sensible heat flux over vegetated surfaces and its performance compares well to the LAS measured sensible heat and other empirical or semi-empirical KB-1 based estimations.

  17. A benchmark-problem specification and calculation using SENSIBL, a one- and two-dimensional sensitivity and uncertainty analysis code of the AARE system

    International Nuclear Information System (INIS)

    The lack of suitable benchmark problems makes it difficult to test sensitivity codes with a covariance library. A benchmark problem has therefore been defined for one- and two-dimensional sensitivity and uncertainity analysis codes and code systems. The problem, representative of a fusion reactor blanket, has a simple, three-zone /tau/-z geometry containing a D-T fusion neutron source distributed in a central void region surrounded by a thick 6LiH annulus. The response of interest is the 6Li tritium production per source neutron, T6. The calculation has been performed with SENSIBL using other codes from the AARE code system as a test of both SENSIBL and the linked, modular system. The caluclation was performed using the code system in the standard manner with a covariance data library in the COVFILS-2 format but modified to contain specifically tailored covariance data for H and 6Li (Path A). The calculation was also performed by a second method which uses specially perturbed H and Li cross sections (Path B). This method bypasses SENSIBL and allows a hand calculation of the benchmark T6 uncertainties. The results of Path A and Path B were total uncertainties in T6 of 0.21% and 0.19%, respectively. The closeness of the results for this challenging test gives confidence that SENSIBL and the AARE system will perform well for realistic sensitivity and uncertainty analyses

    2014-05-01

    Screenhouses and screen-covers are widely used in arid and semi-arid agriculture to protect crops from direct solar radiation and high wind speed, and to increase water use efficiency. However, accurate estimation of crop water use under screens is still a challenge. The most reliable method that directly measures evapotranspiration, the Eddy Covariance (EC), is both expensive and complex in data collection and processing. This renders it unfeasible for day to day use by farmers. A simpler alternative is the Surface Renewal (SR) technique which utilizes high frequency temperature readings of low-cost fine-wire thermocouples, to estimate the sensible heat flux. Assuming energy conservation and employing relatively cheap complementary measurements, the evapotranspiration can be estimated. The SR technique uses a structure function mathematical analysis that filters out noise and involves a time lag parameter to provide amplitude and time period of a ramp-like temperature signal. This behavior arises from the detachment of air parcels that have been heated or cooled near the surface and sequentially renewed by air parcels from above. While the SR technique is relatively simple to employ, it requires calibration against direct measurements. The aim of this research is to investigate the applicability of the SR technique in two different types of commonly used screenhouses in Israel. Two field campaigns were carried out: In the first campaign we studied a banana plantation grown in a shading screenhouse located in the coastal plain of northern Israel. The second campaign was located in the Jordan Valley region of eastern Israel, where a pepper plantation cultivated in an insect-proof screenhouse, with a much denser screen, was examined. In the two campaigns, SR sensible heat flux estimates were calibrated against simultaneous eddy covariance measurements. To optimize the SR operation, in each campaign fine-wire (50-76 μm) exposed T-type thermocouples were placed at

  19. Variation of fluxes of water vapor, sensible heat and carbon dioxide above winter wheat and maize canopies

    Surface energy fluxes were measured using Bowen-Ratio Energy Balance technique (BREB) and eddy correlation system at Luancheng of Hebei Province, on the North China Plain from 1999 to 2001. Average diumal variation of surface energy fluxes and CO2 flux for maize showed the inverse "U "type. The average peak fluxes did not appear at noon, but after noon. The average peak CO2 flux was about 1.65 mgm-2 s-1. Crop water use efficiency (WUE) increased quickly in the morning, stabilized after 10:00 and decreased quickly after 15:00 with no evident peak value. The ratio of latent heat flux (λE) to net solar radiation (Rn) was always higher than 70% during winter wheat and maize seasons. The seasonal average ratio of sensible heat flux (H) divided by Rn stayed at about 15% above the field surface; the seasonal average ratio of conductive heat flux (G) divided by Rn varied between 5% and 13%, and the average G/Rn from the wheat canopy was evidently higher than that from the maize canopy. The evaporative fraction (EF) is correlated to the Bowen ratio in a reverse function. EF for winter wheat increased quickly during that revival stage, after the stage, it gradually stabilized to 1.0, and fluctuated around 1.0. EF for maize also fluctuated around 1.0 before the later grain filling stage, and decreased after that stage.

  20. Second law analysis of a diesel engine waste heat recovery with a combined sensible and latent heat storage system

    International Nuclear Information System (INIS)

    The exhaust gas from an internal combustion engine carries away about 30% of the heat of combustion. The energy available in the exit stream of many energy conversion devices goes as waste. The major technical constraint that prevents successful implementation of waste heat recovery is due to intermittent and time mismatched demand for and availability of energy. The present work deals with the use of exergy as an efficient tool to measure the quantity and quality of energy extracted from a diesel engine and stored in a combined sensible and latent heat storage system. This analysis is utilized to identify the sources of losses in useful energy within the components of the system considered, and provides a more realistic and meaningful assessment than the conventional energy analysis. The energy and exergy balance for the overall system is quantified and illustrated using energy and exergy flow diagrams. In order to study the discharge process in a thermal storage system, an illustrative example with two different cases is considered and analyzed, to quantify the destruction of exergy associated with the discharging process. The need for promoting exergy analysis through policy decision in the context of energy and environment crisis is also emphasized. - Highlights: → WHR with TES system eliminates the mismatch between the supply of energy and demand. → A saving of 15.2% of energy and 1.6% of exergy is achieved with PCM storage. → Use of multiple PCMs with cascaded system increases energy and exergy efficiency.

The present work deals with the use of exergy as an efficient tool to measure the quantity and quality of energy extracted from a diesel engine and stored in a combined sensible and latent heat storage system. This analysis is utilized to identify the sources of losses in useful energy within the components of the system considered, and provides a more realistic and meaningful assessment than the conventional energy analysis. The energy and exergy balance for the overall system is quantified and illustrated using energy and exergy flow diagrams. In order to study the discharge process in a thermal storage system, an illustrative example with two different cases is considered and analyzed, to quantify the destruction of exergy associated with the discharging process. The need for promoting exergy analysis through policy decision in the context of energy and environment crisis is also emphasized. - Highlights: > WHR with TES system eliminates the mismatch between the supply of energy and demand. > A saving of 15.2% of energy and 1.6% of exergy is achieved with PCM storage. > Use of multiple PCMs with cascaded system increases energy and exergy efficiency.

    Full Text Available Efficient systems for high performance buildings are required to improve the integration of renewable energy sources and to reduce primary energy consumption from fossil fuels. This paper is focused on sensible heat thermal energy storage (SHTES systems using solid media and numerical simulation of their transient behavior using the finite element method (FEM. Unlike other papers in the literature, the numerical model and simulation approach has simultaneously taken into consideration various aspects: thermal properties at high temperature, the actual geometry of the repeated storage element and the actual storage cycle adopted. High-performance thermal storage materials from the literatures have been tested and used here as reference benchmarks. Other materials tested are lightweight concretes with recycled aggregates and a geopolymer concrete. Their thermal properties have been measured and used as inputs in the numerical model to preliminarily evaluate their application in thermal storage. The analysis carried out can also be used to optimize the storage system, in terms of thermal properties required to the storage material. The results showed a significant influence of the thermal properties on the performances of the storage elements. Simulation results have provided information for further scale-up from a single differential storage element to the entire module as a function of material thermal properties.

    The Bay of Bengal (BOB) is known to possess complex thermodynamics which show distinct seasonal patterns. Surface heat fluxes in the BOB are very much dependant on upper ocean heat exchanges and wind. Sensible heat flux (SHF) is also one among those fluxes that depends on air-sea temperature difference and wind. However, this study further proves that a strong relationship exists between barrier layer thickness (BLT) and SHF variability that has not been focussed on in earlier literatures. This study also investigates the seasonal as well as inter-annual variability of SHF and its relationship with BLT and sea surface temperature (SST) patterns in more detail with statistical analyses. It is found that both SST and BLT are responsible for the evolution of SHF signal in the BOB although their effects are spatially distributed. During the post monsoon period, freshwater induced enhanced BLT is more related to SHF than the summer time when effect of SST is found to be dominant. During Indian Ocean Dipole (IOD) years, the correlation between SHF and BLT in the eastern BOB is more pronounced compared to SHF and SST. The western BOB however is dominated by SST variations for the respective IOD phase which also contribute to SHF signals there. Northernmost BOB shows high standard deviation due to river discharge effects.

    For over 15 years, antisense morpholino oligonucleotides (MOs) have allowed developmental biologists to make key discoveries regarding developmental mechanisms in numerous model organisms. Recently, serious concerns have been raised as to the specificity of MO effects, and it has been recommended to discontinue their usage, despite the long experience of the scientific community with the MO tool in thousands of studies. Reviewing the many advantages afforded by MOs, we conclude that adequately controlled MOs should continue to be accepted as generic loss-of-function approach, as otherwise progress in developmental biology will greatly suffer.

    . histolytica has two phases: trophozoite and cyst. Trophozoites are the causal agent of disease. The effective treatment for the amebiasis includes drugs with serious collateral effects. Ivermectin is a macrolid with activity against endoparasites and ectoparasites causing strongiloidosis, filariasis, oncocercosis, scabiasis and pediculosis. The use of ivermectin has been extended almost worldwide; it is recognized as a safe drug. The main objective of this study was to determine in vitro sensibility of trophozoites of E. histolytica was to the treatment with ivermectin. To determine the sensibility of the parasites to the drug, E. histolytica was cultivated in PEHPS medium. During its logarithmic growth phase the trophozoites were exposed to different concentrations of ivermectin. As controls other antiparasitic drugs were used. For each drug, serial dilutions were prepared, and mixed in culture tubes with parasites (2 x 10(4 cells/ml. They were incubated for 72 h and then the percentage of growth inhibition was calculated by Probit analysis. Ivermectin showed activity against trophozoites of E. histolytica. The 50% of growth inhibition of ivermectin was 6.40 mg/ml. This dose was higher than for other anti parasitic drugs. Its activity in vivo in animal models remains to be demonstrated.

    2013-01-01

    Full Text Available This article proposes a new area of research centered on the study of how energy sensibilities—in terms of esthesia which is understood as responsiveness and awareness—are distributed and redistributed. Energy is approached as a polyphonic concept with many meanings, of which none enjoys privileged status. Given this polyphony, the common observation that end-users have no idea (or wrong ideas about their energy consumption loses importance. Instead, unevenly distributed ways of sensing and making sense of energy become the object of study. Drawing on the work of French philosopher Jacques Rancière, the article discusses contemporary distributions of energy sensibilities in domestic settings and how they have been redistributed during the previous two decades. Analysis of visual representations of bathrooms in the largest Norwegian interior lifestyle magazine and 600 real estate advertisements shows how a specific, resource-intensive energy sensibility has become dominant through a politics of refurbishing.

    Choi, M. K.; Morehouse, J. H.

    An analysis of a solar assisted absorption cooling system which employs a combination of phase change on the cold side and sensible heat storage on the hot side of the cooling machine for small commercial buildings is given. The year-round thermal performance of this system for space cooling were determined by simulation and compared against conventional cooling systems in three geographic locations: Phoenix, Arizona; Miami, Florida and Washington, D.C. The results indicate that the hot-cold storage combination has a considerable amount of energy and economical savings over hot side sensible heat storage. Using the hot-cold storage combination, the optimum collector areas for Washington, D.C., Phoenix and Miami are 355 m squared, 250 m squared and 495 m squared, respectively. Compared against conventional vapor compression chiller, the net solar fractions are 61, 67 and 69 percent, respectively.

    The accurate determination of surface-layer turbulent fluxes over urban areas is critical to understanding urban boundary layer (UBL) evolution. In this study, a remote-sensing technique using a large aperture scintillometer (LAS) was investigated to estimate surface-layer turbulent fluxes over a highly heterogeneous urban area. The LAS system, with an optical path length of 2.1 km, was deployed in an urban area characterized by a complicated land-use mix (residential houses, water body, bare ground, etc.). The turbulent sensible heat ( Q H) and momentum fluxes (τ) were estimated from the scintillation measurements obtained from the LAS system during the cold season. Three-dimensional LAS footprint modeling was introduced to identify the source areas ("footprint") of the estimated turbulent fluxes. The analysis results showed that the LAS-derived turbulent fluxes for the highly heterogeneous urban area revealed reasonable temporal variation during daytime on clear days, in comparison to the land-surface process-resolving numerical modeling. A series of sensitivity tests indicated that the overall uncertainty in the LAS-derived daytime Q H was within 20%-30% in terms of the influence of input parameters and the nondimensional similarity function for the temperature structure function parameter, while the estimation errors in τ were less sensitive to the factors of influence, except aerodynamic roughness length. The 3D LAS footprint modeling characterized the source areas of the LAS-derived turbulent fluxes in the heterogeneous urban area, revealing that the representative spatial scales of the LAS system deployed with the 2.1 km optical path distance ranged from 0.2 to 2 km2 (a "micro- a scale"), depending on local meteorological conditions.

    Full Text Available La papa (Solanum tuberosum, como todas las plantas cultivadas, depende de factores atmosféricos; por tanto, las heladas se convierten en un factor limitante para su producción, lo que ha ocasionado que los agricultores opten por cultivar en zonas con alturas superiores a 3.000 msnm, para ampliar la frontera agrícola. En estos sitios, las heladas son más severas, además del daño irreversible a los ecosistemas estratégicos como los páramos ya que la aplicación excesiva de agroquímicos y el sistema de monocultivo hacen que los suelos pierdan sus propiedades y por tanto, la producción disminuye. Por esta razón, el Centro Virtual de la Cadena Agroalimentaria de la papa CEVIPAPA, en convenio con la Universidad Pedagógica y tecnológica de Colombia, UPTC desarrolló un trabajo de investigación con el propósito de reconocer áreas sensibles a heladas en el departamento de Boyacá. El trabajo se desarrolló en los municipios de Toca, Motavita, Cómbita, Úmbita,Ventaquemada, Chíquiza, Tunja, Siachoque, Soracá y Saboyá,donde se evaluó la problemática causada por las heladas en este cultivo; así mismo, se detectaron las zonas de mayor producción, identificando las veredas con mayor incidencia en cada uno de los municipios, con el fin de controlar y mitigar los efectos negativos en el cultivote dicho tubérculo.

Nevertheless, to recover the fluid saturation, it is preferable to use the attenuations.

Exploring emotions as an aspect of public self-fashioning, it focuses on the Dutch statesman Rutger Jan Schimmelpenninck as an early modern example. Schimmelpenninck, like his fellow revolutionaries, radicals and moderates, was familiar with the vocabulary of the French political version of sensibility (Reddy’s sentimentalism with its strong emphasis on sincerity. However, in contrast to France, emotions in Dutch revolutionary politics remained of crucial importance thanks to the emergence of an alternative calm style developed by the moderates, most fully embodied by Schimmelpenninck. Helped in part by his republican friends, he promoted himself by stressing his ‘meekness’ as the virtue of his political leadership, but it was precisely this aspect of his public persona that his Dutch political enemies equated with ‘weakness’. Emotionele ‘self-fashioning’.

Foram coletados dados de saldo de radiação, fluxo de calor no solo, temperatura e umidade do solo, temperatura e umidade relativa do ar, velocidade do vento e precipitação pluvial, os quais eram lidos a cada minuto, e armazenados, em uma central de aquisição de dados, como médias a cada 30 min, com exceção da pluviometria, cujo valor foi totalizado no período. Obteve-se excelente concordância entre H_A e H_B, com um índice "d " de 0,980, um erro padrão (EP de 14,88 W m-2, e sem diferença significativa entre H_A e H_B, pelo teste t-Student. Deste modo, o método aerodinâmico pode ser usado em conjunto com medidas de saldo de radiação e de fluxo de calor no solo, para se estimar o fluxo de calor latente e, consequentemente, a evapotranspiração da cultura do feijão-caupi, para as condições edafoclimáticas do Brejo Paraibano.A study was performed to compare the bulk aerodynamic (H_A and Bowen ratio energy balance (H_B methods in the estimation of the sensible heat flux in a cowpea crop. Data of net radiation, soil heat flux, soil water content, soil temperature, air temperature, relative humidity, wind speed and rainfall were collected on 30-min time intervals in an area of 4 ha belonging to the municipality of Areia, PB (6º 58' 12" S e 35º 42' 15" W, 620 m. Results showed that there was a good agreement between H_A and H_B with an index "d" of 0.98 and standard error of estimate (SEE of 14.88 W m-2, no significant difference between H_A H_B, by the t-Student test. Thus, the bulk aerodynamic method can be used in conjunction with measurements of net radiation and soil heat flux to estimate the evapotranspiration of the cowpea under soil and climatic condition of

  8. Soil and canopy CO2, 13CO2, H2O and sensible heat flux partitions in a forest canopy inferred from concentration measurements

    International Nuclear Information System (INIS)

    A canopy scale model is presented that utilises Lagrangian dispersal theory to describe the relationship between source distribution and concentration within the canopy. The present study differs from previous studies in three ways: (1) source/sink distributions are solved simultaneously for CO2, 13CO2, H2O and sensible heat to find a solution consistent with leaf-level constraints imposed by photosynthetic capacity, stomatal and boundary layer conductance, available energy and carbon isotopic discrimination during diffusion and carboxylation; (2) the model is used to solve for parameters controlling the nonlinear source interactions rather than the sources themselves; and (3) this study used plant physiological principles to allow the incorporation of within- and above-canopy measurements of the 13C/12C ratios of CO2 as an additional constraint. Source strengths of CO2, H2O, sensible heat and 13CO2 within a Siberian mixed-coniferous forest were constrained by biochemical and energy-balance principles applied to sun and shaded leaves throughout the canopy. Parameters relating to maximum photosynthetic capacity, stomatal conductance, radiation penetration and turbulence structure were determined by the optimisation procedure to match modelled and measured concentration profiles, effectively inverting the concentration data. Ground fluxes of CO2, H2O and sensible heat were also determined by the inversion. Total ecosystem fluxes predicted from the inversion were compared to hourly averaged above-canopy eddy covariance measurements over a ten-day period, with good agreement. Model results showed that stomatal conductance and maximum photosynthetic capacity were depressed due to the low temperatures experienced during snow melt; radiation penetrated further than simple theoretical predictions because of leaf clumping and penumbra, and stability effects were important in the morning and evening. The inversion was limited by little vertical structure in the concentration

    The influence of spatial scales on surface fluxes is an interesting but not fully investigated question. This paper presents an analysis on the influence of spatial scales on surface fluxes in the north Tibetan Plateau based on eddy covariance (EC) and large aperture scintillometer (LAS) data at site Nagqu/BJ, combined with the land surface temperature (LST) and normalized difference vegetation index (NDVI) of moderate-resolution imaging spectroradiometer (MODIS). The analysis shows that sensible heat fluxes calculated with LAS data (H_LAS) agree reasonably well with sensible heat fluxes calculated with EC data (H_EC) in the rain and dry seasons. The difference in their footprints due to the wind direction is an important reason for the differences in H_EC and H_LAS. The H_LAS are statistically more consistent with H_EC when their footprints overlap than when their footprints do not. A detailed analysis on H_EC and H_LAS changes with net radiation and wind direction in rain and dry season indicates that the spatial heterogeneity in net radiation created by clouds contributes greatly to the differences in H_EC and H_LAS in short-term variations. A significant relationship between the difference in footprint-weighted averages of LST and difference in H_EC and H_LAS suggests that the spatial heterogeneity in LST at two spatial scales is a reason for the differences in H_EC and H_LAS and that LST has a positive correlation with the differences in H_EC and H_LAS. A significant relationship between the footprint-weighted averages of NDVI and the ratio of sensible heat fluxes at two spatial scales to net radiation (H/Rn) in the rain season supports the analysis that the spatial heterogeneity in canopy at two spatial scales is another reason for differences in H_EC and H_LAS and that canopy has a negative correlation with (H/Rn). An analysis on the influence of the difference in aerodynamic roughness lengths at two spatial scales on sensible heat fluxes shows that the

    This study tries to show how Jane Austen’s Sense and Sensibility is an actual representation of women’s social situation at the beginning of the nineteenth Century in England. Austen’s criticism is covered by the two sisters’ romances and therefore it may be challenging to identify it. Even though Austen does not tell us explicitly what the problem was she clearly presents it without naming it, pointing out the consequences emerged by that problem. Austen’s novel reports the stark and unjust ...

  16. Plain film, CT and MRI sensibility in the evaluation of intraorbital foreign bodies in an in vitro model of the orbit and in pig eyes

    International Nuclear Information System (INIS)

    Detection and characterization of intraorbital foreign bodies (IFB) is fundamental in acute trauma setting, preventing inflammatory sequelae or complications related to IFB movements when a MRI study is planned. Papers concerning plain film and CT sensibility in IFB detection show controversial results. For this reason we investigated plain film, CT and MRI sensibility in the evaluation of IFB. For an in vitro model, specimens of dry and fresh wood, glass, iron, plastic and graphite were immersed in animal lard and in a 0.9 % sodium chloride plus 3.5 g/dl human serum albumin solution. Specimens of different size and nature where also implanted into enucleated pig eyes. Air bubbles were introduced also. Plain film, CT and MRI investigation were performed. Plain films underestimated intraocular IFB as plastic, fresh or dry wooden IFB were not demonstrated. The CT study was always able to depict and differentiate IFB according to the attenuation values. Severe artefacts prevented demonstration of iron, glass and graphite IFB on MRI, whereas plastic or wooden IFB were always detected. Despite radiographs have been suggested as a prerequisite for MR imaging, because our results showed plain film to underestimate radiolucent IFB, we suggest CT as the modality of choice when IFB has to be ruled out.

  17. Comparative study of the sensibility of Metacercaria cysts of Phagicola Faust, 1920 (Trematoda: Heterophyidae) to ionizing radiation and to freezing in raw mullets Mugil Linnaeus, 1758 (Pisces: Mugilidae)

    International Nuclear Information System (INIS)

    Foodborne illnesses have been a growing concern to the governments, international organizations and consumers, mainly regarding the damages they cause to human health. This issue is the result of the substitution of imported food habits, which enable the consumption of raw fish or wrongly prepared fish. Among the emergent parasitic zoonosis, the Fagicolose stands out. It is transmitted by Phagicola longa, a trematoda of great importance in public health and responsible for high percentages of Mugilidae infections, that is able to produce humans' parasitism. In this experiment, the studies were focused to the radio sensibility of metacercaria of Phagicola longa exposed to a treatment with ionizing radiation (gamma rays and electron beams) and the sensibility to freezing, in artificially infected fish. Some data were acquired regarding the occurrence of Phagicola longa in mullets bought in the local market, the freezer temperature of 10 domestic refrigerators, and the origin and preservation of the mullets in some Japanese-type restaurants in Sao Paulo. The results indicated more effectiveness in the treatment with the electron accelerator, as well as with the freezing at the temperature of-16 deg C. (author)

  18. On the Equality Assumption of Latent and Sensible Heat Energy Transfer Coefficients of the Bowen Ratio Theory for Evapotranspiration Estimations: Another Look at the Potential Causes of Inequalities

    Full Text Available Evapotranspiration (ET and sensible heat (H flux play a critical role in climate change; micrometeorology; atmospheric investigations; and related studies. They are two of the driving variables in climate impact(s and hydrologic balance dynamics. Therefore, their accurate estimate is important for more robust modeling of the aforementioned relationships. The Bowen ratio energy balance method of estimating ET and H diffusions depends on the assumption that the diffusivities of latent heat (KV and sensible heat (KH are always equal. This assumption is re-visited and analyzed for a subsurface drip-irrigated field in south central Nebraska. The inequality dynamics for subsurface drip-irrigated conditions have not been studied. Potential causes that lead KV to differ from KH and a rectification procedure for the errors introduced by the inequalities were investigated. Actual ET; H; and other surface energy flux parameters using an eddy covariance system and a Bowen Ratio Energy Balance System (located side by side on an hourly basis were measured continuously for two consecutive years for a non-stressed and subsurface drip-irrigated maize canopy. Most of the differences between KV and KH appeared towards the higher values of KV and KH. Although it was observed that KV was predominantly higher than KH; there were considerable data points showing the opposite. In general; daily KV ranges from about 0.1 m2∙s−1 to 1.6 m2∙s−1; and KH ranges from about 0.05 m2∙s−1 to 1.1 m2∙s−1. The higher values for KV and KH appear around March and April; and around September and October. The lower values appear around mid to late December and around late June to early July. Hourly estimates of KV range between approximately 0 m2∙s−1 to 1.8 m2∙s−1 and that of KH ranges approximately between 0 m2∙s−1 to 1.7 m2∙s−1. The inequalities between KV and KH varied diurnally as well as seasonally. The inequalities were greater during the non

    In this paper, a land surface temperature data assimilation scheme is developed based on Ensemble Kalman Filter (EnKF) and Common Land Model version 1.0 (CLM), which is mainly used to improve the estimation of the sensible and latent heat fluxes by assimilating MODIS land surface temperature (LST) products. Leaf area index (LAI) is also updated dynamically by MODIS LAI products. In this study, the relationship between the MODIS LST and the CLM surface temperature is determined and taken as the observation operator of the assimilation scheme. Meanwhile, the MODIS LST is compared with the ground-measured surface temperature, and the Root Mean Square Error (RMSE) is taken as the observation error. The scheme is tested and validated based on measurements in three observation stations (Blackhill, Bondville and Brookings) of Ameriflux. Results indicate that data assimilation method improves the estimation of surface temperature and sensible heat flux. The RMSE of sensible heat flux reduced from 81.5W·m~(-2) to 58.4W·m~(-2) at the Blackhill site, from 47.0W·m~(-2) to 31.8W·m~(-2) at the Bondville site, from 46.5W·m~(-2) to 45.1W·m~(-2) at the Brookings site. The RMSE of latent heat fluxes reduced from 88.6W·m~(-2) to 57.7W·m~(-2) at the Bondville site, from 53.4W·m~(-2) to 47.2W·m~(-2) at the Blackhill site. In addition, it is a practical way to improve the estimation of sensible and latent heat flux by assimilating MODIS LST into land surface model.%基于集合卡尔曼滤波和通用陆面模型(CLM 1.0)发展了一个地表温度的同化系统.这个系统同化了MODIS温度产品,并将MODIS的叶面积指数引入CLM模型中,主要用于改进地表水热通量的估算精度.将CLM输出的地表温度与MODIS地表温度建立关系,并作为同化系统的观测算子.将MODIS地表温度与实测地表温度进行了比较,将其均方差(Root Mean Square Error,RMSE)作为观测误差.选取3个美国通量网站点(Blackhill、 Bondville

  6. A comparison of THI indices leads to a sensible heat-based heat stress index for shaded cattle that aligns temperature and humidity stress

    2016-01-01

    The combined temperature-humidity heat stress is estimated in farm animals by indices derived of an index based on human thermal comfort sensation. The latter index consists of temperature and humidity measures that sum to form the temperature-humidity index (THI). The hitherto unknown relative contribution of temperature and humidity to the THI was examined. A temperature-humidity data set (temperature 20-42 °C and relative humidity 10-70 %) was used to assess by regression procedures the relative weights of temperature and humidity in the variance of THI values produced by six commonly used heat stress indices. The temperature (Ta) effect was predominant (0.82-0.95 of variance) and humidity accounted for only 0.05 to 0.12 of THI variance, half of the variance encountered in animal responses to variable humidity heat stress. Significant difference in THI values was found between indices in the relative weights of temperature and humidity. As in THI indices, temperature and humidity are expressed in different physical units, their sum has no physical attributes, and empirical evaluations assess THI relation to animal responses. A sensible heat THI was created, in which at higher temperatures humidity reaches 0.25 of sensible heat, similarly to evaporative heat loss span in heat stressed animals. It relates to ambient temperature-humidity similarly to present THI; its values are similar to other THI but greater at higher humidity. In warm conditions, mean animal responses are similar in both indices. The higher sensitivity to humidity makes this index preferable for warm-humid conditions.

    A medial incision is a common surgical technique to obtain access to the abdomen. Thereby, the muscles involved in movement are manipulated, leading to post-operative restrictions in mobility and pain determined by movement. The aim of this pilot study was to assess the impact of a pre-operative training session using the Viv-Arte model, which is based on kinesthetic mobilisation principles. The parameters to be measured were mobility, pain, and length of hospital stay for patients, who were undergoing elective medial laparotomy. In addition, the study tested the research design and to identify possible effect sizes. The method chosen was a prospective, randomised, controlled, and unblinded design. Twenty-seven patients were involved (median=63 years, 19 of the patients were male) who were to have a medial incision for cystectomy. The intervention involved pre-operative training of post-operative mobility techniques. Mobility was tested using the "Mobilitätstest für Patienten im Akutkrankenhaus (MOTPA) (Mobility test for patients in hospital)"; pain intensity was assessed using the visual analogue scale. The intervention and control groups were comparable for all variables. There were no significant differences in the two groups related to the objectives. It is possible that the study groups or the operationalisation were not appropriate for testing the effects of the intervention. It seems important to continue to develop instruments that are appropriate for measuring the effect of mobility-related interventions. PMID:19173175

    With the purpose of observing the radio sensibility in two species of pseudo cereals group (Amaranthus hypochondria cus and Chenopodium berlandieri subsp. nuttalliae), germplasm of 4 amaranth genotypes was irradiated (A-21-0-10, Mixquic-09, M-2 and M-6) and 4 huauzontle genotypes (H-18, H-19, H-10 and red Chia) in the Gamma Irradiator of the ININ in a dose range of 50 to 500 Gy with intervals each 50 Gy and a treatment witness without irradiating. The evaluation of the material was carried out in three stages: 1) the pheno logy and morphology was evaluated during the plants development in each treatment under greenhouse conditions; 2) the radio sensibility was evaluated at molecular level by means of molecular markers type Ssr (Simple Sequence Repeats); and 3) the irradiated seeds were analyzed by under vacuum electronic microscopy. According to the results, the pheno logy phases were ahead in lower doses to 250 Gy for amaranth and higher doses to 150 Gy for huauzontle, there being a morphological variation in leaves and cob. The morphological variables were favored in dose from 50 to 200 Gy for amaranth, while in huauzontle the morphology presented more response variation to the radiation. In the DNA, the 21 Ssr were 100% polymorphic in amaranth and 97% polymorphic in huauzontle, being one of the more polymorphic the QCA0005 in amaranth and QCA0005 in huauzontle. The generated dendrograms showed greater similarity between Mixquic-09 and M-2 (amaranth) and between H-19 and H-10 (huauzontle). While by treatments, in amaranth the dose of 500 Gy presented most polymorphic difference and in huauzontle was the dose of 200 Gy. The under vacuum electronic microscopy did not show differences in the seed structure while the elemental analysis showed the presence of carbon, oxygen, aluminum, sulfur and calcium as the most common elements and in more concentration carbon and oxygen. For A. hypochondria cus the dose DL{sub 50} (median lethal dose) was between 50 and 100 Gy and

    We discuss the impact of the differential treatment of the roughness lengths for momentum and heat (z_{0m} and z_{0h}) in the flux parametrization scheme of the high-resolution regional model (HRM) for a heterogeneous terrain centred around Thiruvananthapuram, India (8.5°N, 76.9°E). The magnitudes of sensible heat flux ( H) obtained from HRM simulations using the original parametrization scheme differed drastically from the concurrent in situ observations. With a view to improving the performance of this parametrization scheme, two distinct modifications are incorporated: (1) In the first method, a constant value of 100 is assigned to the z_{0m}/z_{0h} ratio; (2) and in the second approach, this ratio is treated as a function of time. Both these modifications in the HRM model showed significant improvements in the H simulations for Thiruvananthapuram and its adjoining regions. Results obtained from the present study provide a first-ever comparison of H simulations using the modified parametrization scheme in the HRM model with in situ observations for the Indian coastal region, and suggest a differential treatment of z_{0m} and z_{0h} in the flux parametrization scheme.

  11. Investigation of the sensibility and the specificity of a nuclear medicine method for determining regional motility disturbances of the left cardiac muscle

    International Nuclear Information System (INIS)

    The reliability of information on the regional motility of the myocardium obtained through nuclear medicine methods (motility scintigram) can be assessed as very high according to the comparisons made. The specificity of a perfusion scan seems - according to our results-to be somewhat lower. The results of the comparisons made indicate a high sensibility of both motility scan and perfusion scan. Allowing for the fact that there is no fixed correlation between a regional perfusion disturbance and a regional motility disturbance of the myocardium with regard to appearance and local intensity it is possible to explain the larger number of different examination results that one obtains when comparing perfusion scans to motility scans or to ventriculograms. Both nuclear medicine methods become less reliable only when the intensity of pathological changes in the left ventricle is less apparent. In conclusion we state that nuclear medicine methods for investigation of regional perfusion and regional motility of myocardiums can justly claim to be a useful non-invasive way - a kind of screening test - for early and undangerous diagnosis of coronary heart diseases.

  12. The effect of misleading surface temperature estimations on the sensible heat fluxes at a high Arctic site – the Arctic Turbulence Experiment 2006 on Svalbard (ARCTEX-2006

    Full Text Available The observed rapid climate warming in the Arctic requires improvements in permafrost and carbon cycle monitoring, accomplished by setting up long-term observation sites with high-quality in-situ measurements of turbulent heat, water and carbon fluxes as well as soil physical parameters in Arctic landscapes. But accurate quantification and well adapted parameterizations of turbulent fluxes in polar environments presents fundamental problems in soil-snow-ice-vegetation-atmosphere interaction studies. One of these problems is the accurate estimation of the surface or aerodynamic temperature T(0 required to force most of the bulk aerodynamic formulae currently used. Results from the Arctic-Turbulence-Experiment (ARCTEX-2006 performed on Svalbard during the winter/spring transition 2006 helped to better understand the physical exchange and transport processes of energy. The existence of an atypical temperature profile close to the surface in the Arctic spring at Svalbard could be proven to be one of the major issues hindering estimation of the appropriate surface temperature. Thus, it is essential to adjust the set-up of measurement systems carefully when applying flux-gradient methods that are commonly used to force atmosphere-ocean/land-ice models. The results of a comparison of different sensible heat-flux parameterizations with direct measurements indicate that the use of a hydrodynamic three-layer temperature-profile model achieves the best fit and reproduces the temporal variability of the surface temperature better than other approaches.

    Full Text Available Los páramos son ecosistemas zonales ubicados principalmente en las montañas tropicales de Centro y Suramérica, aproximadamente entre 3000 y 4500 msnm y conforman un piso altitudinal de las cordilleras de los trópicos. Sus características especiales generan tipologías florísticas, ecológicas, edafológicas, geomorfológicas y climáticas especiales. Tienen gran importancia ecológica, genética y científica, por su flora endémica y paisajes, así como por su función socioeconómica, al ser fundamentales para la regulación hídrica natural regional para el abastecimientode agua a sus ciudades y como medio de soporte de actividades antrópicas. Como hídrosistemas, las cuencas paramunas han sido objeto de análisis cuantitativos de su balance hídrico. En este trabajo se presenta una aproximación de la modelación hidrológica de estos hidrosistemas mediante la integración del modelo AvSWAT, un modelo de precipitación horizontal y un sistema de información geográfica. El modelo se implementó en la cuenca Alta del Río Blanco, una de las principales corrientes hídricas en el Páramo de Chingaza, principal fuente de agua de la ciudad de Bogotá. Se resalta la necesidad de proteger estos sistemas para preservar el régimen de caudales, especialmente los correspondientes a épocas de estiaje. / Páramos are vulnerable zonal ecosystems located in the tropical mountains of Central and South America, approximately between 3000 and 4500 meters above the sea level. Their special characteristics generate particular floral, ecological, edaphological, geomorphological and climatic typologies. Páramos have great ecologic, genetic and scientific importance due to their endemic flora and landscapes, as well as their socio-economical functions, represented by their fundamental roll in water regulation for water supply in some cities downstream. Some efforts have been done to quantify the water balance in these special hydrosystems. This paper presents an approximation to the hydrologic modeling of these hydrosystems, based on the integration of the AvSWAT model, a horizontal precipitation model, and a geographic information system. As a case study, the upper Blanco river basin was analyzed. This basin is one of the principal areas of the Chingaza páramo, the main Bogotá City water supply source. Protection of these ecosystems is stressed in order to preserve flow regimes, mainly those associated with dry conditions.

  18. Conversation Simulation and Sensible Surprises

    Hutchens, Jason L.

    I have entered the Loebner Prize five times, winning the "most humanlike program" category in 1996 with a surly ELIZA-clone named HeX, but failed to repeat the performance in subsequent years with more sophisticated techniques. Whether this is indicative of an unanticipated improvement in "conversation simulation" technology, or whether it highlights the strengths of ELIZA-style trickery, is as an exercise for the reader. In 2000, I was invited to assume the role of Chief Scientist at Artificial Intelligence Ltd. (Ai) on a project inspired by the advice given by Alan Turing in the final section of his classic paper - our quest was to build a "child machine" that could learn and use language from scratch. In this chapter, I will discuss both of these experiences, presenting my thoughts regarding the Chinese Room argument and Artificial Intelligence (AI) in between.

  1. Homoerotic Sensibility in Gypsy Ballads

    Directory of Open Access Journals (Sweden)

    Luis Antonio de Villena

    2011-10-01

    Full Text Available This paper defends that Federico García Lorca’s Gypsy Ballads, far from being a neo-popular work that sings of the Andalusian region; it is a hymn to absolute sex. Gypsy Ballads means open and free exaltation of sexuality, which is expressed through praise and description of masculine positiveness, and through the different faces of virile and macho essence. This paper deals with the elements that ballad after ballad show the predominance of masculine nature, which is extolled by the poet as a choice of his sexual interest. Without making an allusion to biography, Lorca’s homoerotism is stated this way in the very poetic text.

    As spinal cord injury (SCI) trials begin to involve subjects with acute cervical SCI, establishing the property of an upper limb outcome measure to detect change over time is critical for its usefulness in clinical trials. The objectives of this study were to define responsiveness, sensitivity, and minimally detectable difference (MDD) of the Graded Redefined Assessment of Strength, Sensibility, and Prehension (GRASSP). An observational, longitudinal study was conducted. International Standards of Neurological Classification of SCI (ISNCSCI), GRASSP, Capabilities of Upper Extremity Questionnaire (CUE-Q), and Spinal Cord Independence Measure (SCIM) were administered 0-10 days, 1, 3, 6, and 12 months post-injury. Standardized Response Means (SRM) for GRASSP and ISNCSCI measures were calculated. Longitudinal construct validity was calculated using Pearson correlation coefficients. Smallest real difference for all subtests was calculated to define the MDD values for all GRASSP subtests. Longitudinal construct validity demonstrated GRASSP and all external measures to be responsive to neurological change for 1 year post-injury. SRM values for the GRASSP subtests ranged from 0.25 to 0.85 units greater than that for ISNCSCI strength and sensation, SCIM-SS, and CUE-Q. MDD values for GRASSP subtests ranged from 2-5 points. GRASSP demonstrates good responsiveness and excellent sensitivity that is superior to ISNCSCI and SCIM III. MDD values are useful in the evaluation of interventions in both clinical and research settings. The responsiveness and sensitivity of GRASSP make it a valuable condition-specific measure in tetraplegia, where changes in upper limb neurological and functional outcomes are essential for evaluating the efficacy of interventions.

The human vascular endothelial growth factor receptor 1 (VEGF-R1, Flt-1) was used as a biorecognition element for the first time. The immobilization of VEGF-R1 on glassy carbon electrodes was carried out using layer-by-layer covalent attachment of VEGF-R1. The electrochemical properties of the layers constructed on the electrodes were characterized by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The differences in electron transfer resistance (R{sub et}) between the working solution and the biosensor surface, recorded by the redox probe K{sub 3}[Fe(CN){sub 6}]/K{sub 4}[Fe(CN){sub 6}], confirmed the binding of VEGF to VEGF-R1. The new biosensor allowed a detection limit of 100 fg mL{sup -1} with a linear range of 100-600 fg mL{sup -1} to be obtained. The biosensor also exhibited good repeatability (with a correlation coefficient of 1.95%), and reproducibility.

    Full Text Available Resumen: Según consideraba el propio José Ángel Valente, su poesía encontraba su origen en un mundo matriarcal, un universo de naturaleza sensible cuyo extremo opuesto lo observamos intensamente tratado en su última etapa creativa, dominada por el deseo de ascender hacia esferas puramente trascendentales donde la palabra encontrará su límite y se prestará, consecuentemente, a su pronta disolución. A través de este artículo estudiaremos aquel ámbito intermedio que va a quedar entre ambos extremos de su obra, coincidente con un espacio presentado a modo de cosmos rico en símbolos, orientados a reunir aquellos estratos materiales con aquellos otros espirituales propios de su creación poética. Abstract: As José Ángel Valente himself used to say, his poetry emerged from a matriarchal universe, a place dominated by water and earth. This sensitive world will be considered opposite to the transcendental object pursued towards the end of his last creative phase. The increasingly abstraction achieved in this phase will pose a well-known language problem: the word will be on the edge of the nothingness. Between these two extremes, a universe full of symbols will be created by connecting elements of the poet’s universe. All of these symbols, in their perfect way, will express the full unity between the material and spiritual aspects of Valente’s poetry.

    Full Text Available Abstract Background With surveys suggesting that exceeding guidelines for 'sensible' alcohol intake is commonplace, the health and social impact of modifying intake on a population level is potentially considerable. If public health interventions are to be successfully implemented, it is first important to identify correlates of such behaviours, including socioeconomic disadvantage. This was the aim of the present study. Methods Population-representative cohort study of 576 men from the West of Scotland. Data on life course socioeconomic position were collected in 1988 (at around 55 years of age. Alcohol consumption patterns (detailed seven day recall and problem drinking (CAGE questionnaire were ascertained in 1990/2 (at around 59 years of age. A relative index of inequality was computed to explore the comparative strength of different indicators of social circumstances from different periods of the life course. Results Socioeconomic adversity in both early life and in adulthood was related to an increased risk of exceeding the weekly and daily alcohol guidelines, with adult indicators of socioeconomic position revealing the strongest associations. Of these, material indicators of socioeconomic deprivation in adulthood – car ownership, housing tenure – were marginally more strongly related to heavy alcohol intake and problem drinking than education, income and occupational social class. A substantial proportion of the influence of early life deprivation on alcohol intake was mediated via adult socioeconomic position. Similar results were apparent when problem drinking was the outcome of interest. Conclusion In men in this cohort, exposure to disadvantaged social circumstances across the lifecourse, but particularly in adulthood, is associated with detrimental patterns of alcohol consumption and problem drinking in late middle age.

    The Solar System Ballet was developed in order for students of all ages to learn about the planets, their motions, their distances, and their individual characteristics. To teach people about the structure of our Solar System can be revealing and rewarding, for students and teachers. Little ones (and some bigger ones, too) often cannot yet grasp theoretical and spatial ideas purely with their minds. Showing a video is better, but being able to learn with their bodies, essentially being what they learn about, will help them understand and remember difficult concepts much more easily. There are three segments to this activity, which can be done together or separately, depending on time limits and age of the students. Part one involves a short introductory discussion about what students know about the planets. Then students will act out the orbital motions of the planets (and also moons for the older ones) while holding a physical model. During the second phase we look at the structure of the Solar System as well as the relative distances of the planets from the Sun, first by sketching it on paper, then by recreating a scaled version in the class room. Again the students act out the parts of the Solar System bodies with their models. The third segment concentrates on recreating historical measurements of Earth-Moon-Sun system. The Solar System Ballet activity is suitable for grades K-12+ as well as general public informal learning activities.

    The proposed 100-MWe Commercial Plant Thermal Storage System (TSS) employs sensible heat storage using dual liquid and solid media for the heat storage in each of four tanks, with the thermocline principle applied to provide high-temperature, extractable energy independent of the total energy stored. The 10-MW Pilot Plant employs a similar system except uses only a single tank. The high-temperature organic fluid Caloria HT43 and a rock mixture of river gravel and No. 6 silica sand were selected for heat storage in both systems. The system design, installation, performance testing, safety characteristics, and specifications are described in detail. (WHK)

    Full Text Available This papers objective is to elaborate some approaches among communication, aesthetics and politics through the investigation of the notions of distribution of the sensible, dissensus, resistance and community. The concept of distribution of the sensible shows the existing gaps in the common of a community and it fragments the idea of the great social body protected by shared certainties, widely joined by equalitarian principles previously settled and almost never tested. The approaches proposed by Parret, Habermas and Rancire helped me to show that the intersections among communication, aesthetics and politics emerge in the field of placed contact with the other, in the dissensus related to the attempt of establishing links between broken universes and in the constant resistance to the permanence of these bonds.Este artigo busca traar algumas vias de aproximao entre a comunicao, a esttica e a poltica, por meio da explorao das noes de partilha do sensvel, dissenso, resistncia e comunidade.

    Full Text Available Observations of the scale-dependent turbulent fluxes, variances, and the bulk transfer parameterization for sensible heat above, within, and beneath a tall closed Douglas-fir canopy in very weak winds are examined. The daytime sub-canopy vertical velocity spectra exhibit a double-peak structure with peaks at timescales of 0.8 s and 51.2 s. A double-peak structure is also observed in the daytime sub-canopy heat flux co-spectra. The daytime momentum flux co-spectra in the upper bole space and in the sub-canopy are characterized by a relatively large cross-wind component, likely due to the extremely light and variable winds, such that the definition of a mean wind direction, and subsequent partitioning of the momentum flux into along- and cross-wind components, has little physical meaning. Positive values of both momentum flux components in the sub-canopy contribute to upward transfer of momentum, consistent with the observed sub-canopy secondary wind speed maximum. For the smallest resolved scales in the canopy at nighttime, we find increasing vertical velocity variance with decreasing timescale, consistent with very small eddies possibly generated by wake shedding from the canopy elements that transport momentum, but not heat. Unusually large values of the velocity aspect ratio within the canopy were observed, consistent with enhanced suppression of the horizontal wind components compared to the vertical by the very dense canopy. The flux–gradient approach for sensible heat flux is found to be valid for the sub-canopy and above-canopy layers when considered separately in spite of the very small fluxes on the order of a few W m−2 in the sub-canopy. However, single-source approaches that ignore the canopy fail because they make the heat flux appear to be counter-gradient when in fact it is aligned with the local temperature gradient in both the sub-canopy and above-canopy layers. While sub-canopy Stanton numbers agreed well with values

    Full Text Available Diabetic neuropathy is an important complication of the disease, responsible for ulceration and amputation of the foot. Prevention of these problems is difficult mainly because there is no method to correctly access sensibility on the skin of the foot. The introduction of the Pressure-Specified Sensory Device (PSSD TM in the last decade made possible the measurement of pressure thresholds sensed by the patient, such as touch, both static and in movement, on a continuous scale. This paper is the first in Brazil to report the use of this device to measure cutaneous sensibility in 3 areas of the foot: the hallux pulp, the calcaneus, and the dorsum, which are territories of the tibial and fibular nerves. METHOD: Non-diabetic patients were measured as controls, and 2 groups of diabetic patients - with and without ulcers - were compared. The PSSD TM was used to test the 3 areas described above. The following were evaluated: 1 PS (1-point static, 1 PD (1-point dynamic, 2 PS (2-points static, 2 PD (2-points dynamic. RESULTS: The diabetic group had poorer sensibility compared to controls and diabetics with ulcers had poorer sensibility when compared to diabetics without ulcers. The differences were statistically significant (P A neuropatia diabética é uma complicação importante do Diabetes melitus, responsável por ulcerações e amputações de membros inferiores.

    Pierre Gy's equation is widely used in ore sampling. This equation is based in four parameters: shape factor, size distribution factor, mineralogical factor and liberation factor. The usual practice is to consider fixed values for the shape and size distribution factors. This practice does not represent well several important ores. The mineralogical factor considers only one specie of interest and the gangue, leaving out other cases such as polymetallic ores where there are more than one species of interest. A sensibility analysis to the Gy's equation factors was done and a procedure to determine specific values for them was developed and presented in this work. mean ore characteristics, associated with an insecure use of the actual procedure, were determined. finally, for a case study, the effects of using each alternative were evaluated.

    Based on previous research on sensible heat flux, we investigate it from different aspects usingGAME/Tibet data measured during 6 June-13 September, 1998. This work consists of the derivationof the surface heat flux equation, analysis on counter-gradient heat transference, comparison betweentwo different methods to compute the sensible heat flux, and investigation on the calculation scheme ofsensible heat flux in the Simple Biosphere model 2 (SiB2) with relevant simulation. By improving twoprevious formulations, an integrated formulation for calculating surface heat flux is given. Secondly, usingthe measured data, the counter-gradient heat flux is clarified, leading to the fact that buoyancy plays animportant role in the sensible heat transfer process. It is concluded that (1) energy imbalance is a commonphenomenon resulting from the use of the traditional closure scheme on the heterogeneous underlyingsurface because the measured ensemble heat fluxes by eddy correlation contain the effect of nonlocal parcelmovements; and (2) nonlocal parcel movement deserves more attention in any future heat flux study.%回顾了前人对感热通量的分析研究,详细分析了计算感热通量公式的推导过程.结合GAME/Tibet那曲近地面通量观测站1998年6月6日到9月13日的观测资料验证了近地面层逆梯度热输送现象的存在;并比较了两种不同计算感热通量的方法.同时,对简化生物圈模式(SiB2)计算感热通量方案进行了分析.主要结论有:(1)由于用涡旋相关法测量得到的总体感热通量本身已经包含了非局地热(冷)泡运动的影响,所以在非均匀下垫面上,传统的闭合方案必然会"遭遇"能量不平衡.这里,非均匀下垫面可能是导致能量不平衡的关键所在.(2)在今后的有关热通量研究中,有必要仔细研究非局地热(冷)泡运动对热通量的贡献,而为了更好地理解这种贡献,应用陆面过程模式研究能量平衡是必需的.

  11. Determination of the Sensibility Factors for TLD-100 Powder on the Energy of X-Ray of 50, 250 kVp; 192Ir, 137Cs and 60Co

    International Nuclear Information System (INIS)

    TLD-100 powder is calibrated in terms of absorbed dose to water Dw, using the protocols AAPM TG61, AAPM TG43 and IAEA-TRS 398, for the energy of RX 50, 250 kVp, 137Cs and 60Co respectively. The calibration curves, TLD Response R versus Dw, are fitted by weighted least square by a quadratic polynomials; which are validated with the lack of fit and the Anderson-Darling normality test. The slope of these curves corresponds to the sensibility factor: Fs R/DW, [Fs] = nC Gy-1. The expanded uncertainties U's for these factors are obtained from the ANOVA tables. Later, the Fs' values are interpolated using the effective energy hvefec for the 192Ir. The SSDL sent a set of capsules with powder TLD-100 for two Hospitals. These irradiated them a nominal dose of Dw = 2 Gy. The results determined at SSDL are: for the Hospital A the Dw is overestimated in order to 4.8% and the Hospital B underestimates it in the range from -1.4% to -17.5%

  12. Communication on radiation safety: ability and sensibility

    International Nuclear Information System (INIS)

    Nuclear Communication Issues today, combine aspects of nuclear science, public approach and psychological subjects. The principal objectives are to systematize nuclear public information and to prepare researchers or communicators in a position to comment on the nuclear issues of our stage. The programme should focused on progress of nuclear energy, public perception of risk, conflicts among scientists, as the radiation effect at low doses, and how nuclear industry and scientists may better communicate information concerning the potential for hazard to property, health and the environment. There will be occasions where the competent authority should have formal link with other organizations, as in case of abnormal situation or emergency. Particular attention should be paid to the exchange of distinct parts in order to avoid misinterpretation or mistakes when divulging information to the public.Communication is emphasized in the IAEA Basic Safety Standards, [1] as well as, the current approach created to enlarge the relationship between man, practices and protection by the encouragement of a better understanding and implementation of the Safety Culture concept. The application of this concept involves better protection on Radiation Safety to workers, public and environment not only reducing accidents, but also avoiding unnecessary stresses and strains due to intensified operations. This means an advance towards the humanization of practices, equally observed by industrialized and developing countries. Finally, this paper also comment about two very important lessons that there were not yet learned as in reality necessary, considering the goals for a competent Nuclear Communication: the psychological effects of Chernobyl accident in April 1986 resulted from the lack of public information; the psychological effects of the Radiological Accident in Goiania resulted from the misunderstanding of the basic concept of ionizing radiation, which was translated into fear and depression of the population and stigmatization and discrimination against the victims and the main commercial products of the city.

    Full Text Available The olfactory system plays a leading role in the perception of flavors, even though we experience this perception in our oral cavity as "taste". Without a sense of smell, food loses all but its most elementary flavor qualities. Smell begins in the periphery with the olfactory epithelium, a thin tissue lining the bones of the upper nasal cavity (1. Residing in this tissue are upwards of several million bipolar shaped cells which are the primary olfactory sensory neurons. At one end of these neurons there are hair-like projections called cilia. Residing within the membranes of these cilia are the proteins that make up the molecular machinery for detecting odor molecules that are breathed into the nasal cavity and become adsorbed to the mucus (2. These include, first and foremost, the receptor protein or “odor receptor”. This protein, made up of just over 300 amino acids strung together like pearls on a string, has a unique shape, including a pocket that allows for the entry and binding of specific odor molecules, much the way a lock permits certain shaped keys to be inserted. Again in analogy with a lock and key, where the right shaped key can open the lock, when a molecule fits into the binding pocket it is able to activate the receptor. This sets in motion a series of events through "second messenger" proteins which very rapidly cause an electrical change in the state of the sensory neuron. It is this electrical change, encoded in trains of changing voltage impulses, that signals to the brain the presence of a particular odor molecule. There are nearly 400 different odor receptors expressed by the various neurons of the epithelium in humans (3. However even this large number of receptors is insufficient to explain our ability to detect and identify many thousands of diverse chemicals as odorants (one recent report claims we have the potential to discriminate trillions!. It is hypothesized that there is a combinatorial code in which any given odor can be detected by several receptors and any given receptor can bind any of several presumably related odors. In our analogy, the keys fit very loosely to differing degrees into many locks. Chemists are particularly interested in those parts of a molecule that are likely to participate in various sorts of reactions and synthetic manipulations. These would include such things as the functional group (aldehyde, acid, ester, etc. or if there are double bonds or charge carrying atoms. However, what is relevant to the synthetic chemist may not be important to the biological system, and in particular to the odor receptor protein. Thus we should begin by taking a biological approach to odor chemistry. For example the definition of an odorant cannot be made chemically – many chemical compounds that appear nearly identical to a known odorant may have a different smell or none at all. The only definition of an odorant is that it binds to an odor receptor to give rise to a biological response. Precisely what parts of a chemical compound influence that binding is one of the most challenging questions in biology. The actual perception of an odorant depends on the particular combination of receptors that are activated. In a complex mixture of tens to hundreds of different odor molecules this can quickly become a very complicated matrix of activated receptors with an astronomical number of combinations. An open question is whether evolution has perhaps found a simplified way of performing this apparently incalculable task. One possible solution would be the existence of a few dozen common chemical structures that would serve as primary features from which all other odors are constructed. This would be similar to the way the visual system can perceive thousands of hues of light by combining only three (blue, green and red primary “colors” or wavelengths. Although the idea of primaries in olfaction has been discussed for several decades it was largely abandoned after the discovery of the large family of receptors. Now we are recognizing that it might be required after all, and with new molecular tools we may be able to understand better the basic mystery of how biological entities encode chemicals. The perception of the odor code is affected by whether we are activating the olfactory receptor cells by sniffing in ("orthonasal smell" or by breathing out ("retronasal smell". When breathing in, the odor chemical code is perceived as smell. When breathing out during eating, the code is combined with the input from the other senses to form the merged perception of flavor. This challenges current research in analyzing the specific roles of smell in flavors that lead to healthy or unhealthy eating, as the talks at this conference document.

    Foodborne illnesses have been a growing concern to the governments, international organizations and consumers, mainly regarding the damages they cause to human health. This issue is the result of the substitution of imported food habits, which enable the consumption of raw fish or wrongly prepared fish. Among the emergent parasitic zoonosis, the Fagicolose stands out. It is transmitted by Phagicola longa, a trematoda of great importance in public health and responsible for high percentages of Mugilidae infections, that is able to produce humans' parasitism. In this experiment, the studies were focused to the radio sensibility of metacercaria of Phagicola longa exposed to a treatment with ionizing radiation (gamma rays and electron beams) and the sensibility to freezing, in artificially infected fish. Some data were acquired regarding the occurrence of Phagicola longa in mullets bought in the local market, the freezer temperature of 10 domestic refrigerators, and the origin and preservation of the mullets in some Japanese-type restaurants in Sao Paulo. The results indicated more effectiveness in the treatment with the electron accelerator, as well as with the freezing at the temperature of-16 deg C. (author)

    , due the lower sensibility of buffaloes to poisoning by this plant. Another factor responsible for the smaller number of buffaloes which die due to plant poisoning in the Amazon region, is possibly that buffaloes prefer the lowlands, e.g. temporarily flooded areas, which are the habitat of Arrabidaea bilabiata, the second most important poisonous plant of the Amazon region. This plant is less poisonous than P. marcgravii, and its habitat are the higher not flooded areas. So it would be safer, in order to diminish losses, to breed buffaloes instead of cattle in areas where P. marcgravii occurs. The reason for the greater resistance of buffaloes should be further investigated as a possible prophylactic measure to avoid poisoning by P. marcgravii in cattle. On the other hand, Australian investigators modified genetically the ruminal bacteria Butyrivibrio fibrisolvens by introducing a gene, isolated from a Moraxella sp, which codifies a dehalogenase, capable of hydrolyzing fluoroacetate, the poisonous principle of P. marcgravii. Transferring the genetically modified B. fibrisolvens into the rumen of animals, which consume plants that contain fluoroacetate, would be a viable method to control that poisoning through a ruminal detoxifying process for the toxin. Through preliminary contacts, the director of the consorcium in Australia, responsible for the modification of the bacteria, declared that he is interested to sell the technology to our country, but it would be necessary to know if it is permitted to introduce into Brazil the genetically modified bacteria. If allowed, it would be necessary to perform investigations on the viability and the methodology for using this bacteria to control P. marcgravii poisoning in our country.

Those patients were sent to colposcopy under the following criteria: 1 previous abnormal cytopathological exams, 2 Indicative clinical data or, 3 Suspected lesions on gynecological exam. The statistical significance analysis of the results was done using the chi-square test. Sensibility, specificity, positive predictive value (PPV and negative predictive value (NPV were also determined.RESULTS: The patients' mean age was 30.2 (±10.9. Cytopathological capability of identifying lesions was 50% when compared to histology. Its specificity was 77%, the sensibility 41%, the PPV 74%, and the NPV 45%. Colposcopy capability of identifying lesions was 50%. Its sensibility, specificity, PPV and NPV were 96%, 19%, 65% and 75% respectively. The two methods associated were capable of identifying 63% of the lesions.CONCLUSIONS: Cytopathology was a high specificity exam, while colposcopy from those selected patients had a high sensibility. Colposcopy association with cytopathological screening, on those selected patients, significantly raises the diagnostic accuracy of cervical cancer precursor lesions.

    A simple ‘hands on’ physical model is described which displays analogous behaviour to some aspects of the free electron theory of metals. Using it students can get a real feel for what is going on inside a metallic conductor. Ohms Law, the temperature dependence of resistivity, the dependence of resistance on geometry, how the conduction electrons respond to a potential difference and the concepts of mean free path and drift speed of the conduction electrons can all be explored. Some quantitative results obtained by using the model are compared with the predictions of Drude’s free electron theory of electrical conduction.

    Objective: To investigate the effect of S-Equol on insulin sensibility and IRS-1 expression of HepG2 exposed to high glucose and the possible molecular mechanisms. Methods: HepG2 cells were cultured in high glucose in the absence or presence 1,10, 100 μM S-Eq. Effect of S-Eq on viability of cells was detected by MTT assay. The insulin-stimulated glycogen content of cells was evaluated by anthrone-sulfuric colorimetry. The mRNA and protein expression levels of IRS-1 were estimated by Real-time PCR and Western blot analysis, respectively. Results: There was no significant influence on viability of HepG2 cells by S-Eq. But the insulin sensibility was significantly increased by S-Eq and insulin-stimulated glycogen content was up-regulated by S-Eq at the concentration of 10u,M(P>0.01). We also found S-Eq significantly raised the levels of IRS-1 mRNA and protein. Conclusion: S-Eq can effectively improve insulin sensibility of HepG2 cells exposed to high glucose by regulating IRS-1 and this may be the critical theoretical basis of anti-diabetic effect of S-Eq.%目的:研究S型雌马酚(S-Equol,S-Eq)对高糖培养HepG2人肝癌细胞株胰岛素敏感性和胰岛素受体底物(insulin receptor substrate,IRS)-1表达的影响并探讨其可能的分子机制.方法:高糖培养HepG2细胞,1、10、100 μM S-Eq处理细胞后,MTT法检测细胞活力,硫酸蒽酮比色法检测胰岛素刺激细胞糖原合成量,Realtime PCR和Western blot法分别检测IRS-I mRNA及蛋白表达变化.结果:S-Eq对HepG2细胞活力无明显影响,但显著改善高糖培养条件下HepG2细胞胰岛素敏感性,其中10 μM S-Eq+H组胰岛素刺激后细胞糖原合成量上升最为显著(P<0.01),同时发现,S-Eq能显著上调IRS-1 mRNA和蛋白表达量.结论:S-Eq可能通过调控IRS-1的表达,增强高糖培养HepG2细胞胰岛素敏感性,这可能是S-Eq发挥其抗糖尿病作用的重要理论依据.

    Full Text Available The Deleuzean literature paid relatively little attention to the relationships between Deleuze and cosmology. Yet, Deleuze remains one of the few key contemporary philosophers who stayed connect- ed to the cosmological tradition. The expression of this interest and the contribution to this domain can be found, for example, in his borrowing of James Joyce’s neologism “chaosmos,” admiration for Whitehead’s essay on cosmology, or, following Artaud and Blanchot, in his appeal for an outside of any exteriority. This paper discusses Deleuze’s original cosmological way of thinking and delineates Deleuze’s own c(haosmological affectivity.

    International Nuclear Information System (INIS)

    Various assays measuring tumor radiosensitivity were developed in the early eighties. These assays were based on cell cultures derived from tumor biopsies. In most studies there was no correlation between measured radiosensitivity and treatment outcome. New assays using new techniques (such as measurement of radiation-induced apoptosis, or fluorescence in situ hybridization) have been developed recently. Preliminary results are encouraging, but correlation with treatment outcome is expected to be difficult to demonstrate as multi-various clinical and biological parameters are involved in loco-regional control.

  8. Ionizing radiation M.O.S. dosimeters: sensibility and stability

    International Nuclear Information System (INIS)

    This thesis is a contribution to the study of the ionizing radiation responsivity of P.O.M.S. dosimeters. Unlike the development of processing hardening techniques, our works goal were to increase, on the one hand, the M.O.S. dosimeters sensitivity in order to detect small radiation doses and on the other hand, the stability with time and temperature of the devices, to minimize the absorbed-dose estimation errors. With this aim in mind, an analysis of all processing parameters has been carried out: the M.O.S. dosimeter sensitivity is primarily controlled by the gate oxide thickness and the irradiation electric field. Thus, P.M.O.S. transistors with 1 and 2 μm thick silica layers have been fabricated for our experiments. The radiation response of our devices in the high-field mode satisfactorily fits a Dox2 power law. The maximum sensitivity achieved (9,2 V/Gy for 2μm devices) is close to the ideal value obtained when considering only an unitary carrier-trapping level, and allows to measure about 10-2 Gy radiation doses. Read-time stability has been evaluated under bias-temperature stress conditions: experiments underscore slow fading, corresponding to 10-3 Gy/h. The temperature response has also been studied: the analytical model we have developed predicts M.O.S. transistors threshold voltage variations over the military specifications range [-50 deg. C, + 150 deg. C]. Finally, we have investigated the possibilities of irradiated dosimeters thermal annealing for reusing. It appears clearly that radiation-induced damage annealing is strongly gate bias dependent. Furthermore, dosimeters radiation sensitivity seems not to be affected by successive annealings.

    Full text: Under the new Additional Safeguards Protocol, both the obligations of States to provide safeguards-relevant information as well as the scope of inspections have been considerably expanded. It is apparent that, if this extension is to bring with it an improvement in safeguards effectiveness and efficiency, it should not lead to an amplification of the old situation in which States with large nuclear fuel cycles and minimal motivation to violate are most heavily controlled, while other States with obvious motivations are able to deceive the safeguards system successfully. In the context of the newly emerging, integrated safeguards regime, we address in our paper the determination of a rational basis for the distribution of available inspection resources, both among locations within a controlled State as well as among States themselves. In the spirit of the original conception of the NPT safeguards system, which emphasized objectivity and impartiality, we adopt a formal, quantified point of view. The mathematical framework for quantitative analysis is provided by the theory of rational behavior in strategic decision making (the theory of games). In previous investigations of this kind, two general criteria have been considered and related quantitatively to one another: - the technical capabilities of the inspection authority, expressed as probabilities of detection achievable for hypothetical illegal activities; and - the motivation and priorities of the parties involved, described in terms of their respective utility functions. In the present work we include, additionally, - the technical resources of the controlled states, parameterized by critical conversion times. The notion of critical time and its implications for inspections was introduced for IAEA safeguards a long time ago. The idea is that the illegal construction of a nuclear explosive device, starting, e.g. with plutonium diverted from a declared fuel fabrication plant, takes some critical time, and that this illegal action should be detected within that time. This has been studied in detail recently in the context of a single facility in a single State, whereby sequential and non-sequential game-theoretical models were differentiated. In this paper we extend this investigation by using a very simple non-sequential model with two facilities, which nevertheless captures the basic interaction between the criteria. We place emphasis on the conditions necessary for fulfillment of the fundamental safeguards objective of deterrence and we derive reasonable and intuitively understandable conclusions. Next we consider two States with one facility each. Due to their respective technical resources and competence, the two States may need different critical times for a specified illegal action - if they wish to commit one - even if they start with the same material. Therefore we measure their resources and capability by the respective critical times. We maintain, however, the requirement that the inspectorate detect an illegal action within the critical time in order to fulfill its inspection goals. (author)

    We propose a software architecture for interactive systems which allows integrating the user's emotion. Emotion can be involved in interaction at several levels. In our application case - ballet dance - emotions is explicitely manipulated by the interactive system to produce emotion-wise output. Our architecture model to develop emotion-wise applications is based on the PAC-Amodeus model. We add a branch to this model, divided into three components: Data capture, analysis and cue extraction, and finally interpretation of those cues. We show the different data flows between this architecture's components depending on the entry point of the emotion branch within the system. We then illustrate our model by describing our application case: capturing a ballet dancer's movement to extract the emotions he expresses and use these emotions to generate graphical content that is displayed on stage.

    Many of us, especially since 9/11, have become personally concerned about issues of security, and this is no surprise. Security is near the top of government and corporate agendas around the globe. Security-related stories appear on the front page everyday. How well though, do any of us truly understand what achieving real security involves? In Beyond Fear, Bruce Schneier invites us to take a critical look at not just the threats to our security, but the ways in which we're encouraged to think about security by law enforcement agencies, businesses of all shapes and sizes, and our national governments and militaries. Schneier believes we all can and should be better security consumers, and that the trade-offs we make in the name of security - in terms of cash outlays, taxes, inconvenience, and diminished freedoms - should be part of an ongoing negotiation in our personal, professional, and civic lives, and the subject of an open and informed national discussion.

    1989-03-01

    An experimental study of boiling/evaporative heat transfer from heated spheres in vertical packed beds with downward liquid-vapor flow of Refrigerant-113 was conducted. Surface superheats of 1 to 50{degrees}C, mass flow rates of 1.7 to 5.6 Kg/min, sphere diameters of 1.59 and 2.54 cm, quality (i.e., mass fraction of vapor) of the inlet flow of 0.02 to 1.0, and two surface conditions were considered. Instrumented smooth and rough aluminum spheres were used to measure the heat transfer coefficients under steady state conditions. Heat transfer coefficients were independently determined for each sphere at three values three values of surface superheat. The quantitative results of this extensive experimental study are successfully correlated. The correlation equation for the boiling heat transfer coefficients is presented in terms of a homogeneous model. The correlation may be used in the development of numerical models to simulate the transient thermal performance of packed bed thermal energy storage unit while operating as an evaporator. The boiling of the liquid-vapor flow around the spheres in the packed bed was visually observed with a fiber-optic baroscope and recorded on a videotape. The visualization results showed qualitatively the presence of four distinct flow regimes. One of these occurs under saturated inlet conditions and are referred to as the Low-quality, Medium-quality, and High-quality Regimes. The regimes are discussed in detail in this paper.

    Full Text Available This paper aims at questioning the role of image and imagination in Descartes’ Metaphysics, especially in the Meditations on First Philosophy, by holding both a certain doctrinal or theoretical discourse on image/imagination and the Cartesian use of images/imagination. Besides the fact that this rarely considered perspective prevents from freezing the original text, this strategy allows to highlight the ambiguity of theses notions, revealed through what is doing by the act of imagining compared to the act of conceiving with the understanding.

  2. A Facial Control Method Using Emotional Parameters in Sensibility Robot

    Science.gov (United States)

    Shibata, Hiroshi; Kanoh, Masayoshi; Kato, Shohei; Kunitachi, Tsutomu; Itoh, Hidenori

    The “Ifbot” robot communicates with people by considering its own “emotions”. Ifbot has many facial expressions to communicate enjoyment. These are used to express its internal emotions, purposes, reactions caused by external stimulus, and entertainment such as singing songs. All these facial expressions are developed by designers manually. Using this approach, we must design all facial motions, if we want Ifbot to express them. It, however, is not realistic. We have therefore developed a system which convert Ifbot's emotions to its facial expressions automatically. In this paper, we propose a method for creating Ifbot's facial expressions from parameters, emotional parameters, which handle its internal emotions computationally.

    Avocado bud woods from the c v Hass, were exposed to gamma irradiation in doses ranging from 0 to 45 Gy with 5 Gy intervals between each treatment. This was done to asses the L D50 and the optimum irradiation range for breeding purposes. The irradiated scions (20 per treatment) were grafted on Mexican rootstocks. Four months after irradiation lethality reached 100 % at 45 Gy. The L D50 was estimated at 29.54 Gy and the optimum irradiation dose for breeding ranged between 1.48 and 24.51 Gy which correspond to 70 % and 60 % of survival rate, respectively. (Author)

    The Matrix Metallo-proteinases (M.M.P.) represent a family of Zinc dependent extracellular proteinases able to cleave collectively all the proteins constituting the extracellular matrix. Currently, 23 human M.M.P. have been identified and are characterized by their sequence in amino-acids and their highly conserved 3 D structure. These enzymes are expressed constitutively during the tissue remodeling process. Their over-expression in various diseases tightly related to inflammatory processes (arthritis, emphysema, cancer) described M.M.P. as choice therapeutic targets. However, as the tissue remodeling implicates modification of cellular contacts, M.M.P. appear currently as proteins involved in signalling pathways. Recent works demonstrating that M.M.P. are able to cleave substrates, which are different than proteins constituting the extracellular matrix, reinforce this vision. In order to identify the individual role and the protein expression level of M.M.P. in pathological context, we developed a new technique of functional proteomics dedicated to the detection of active forms of M.M.P. in tumour samples. This technique relied on the development of a new photoaffinity probe, based on the structure of a potent phosphinic inhibitor of M.M.P., allowing targeting and isolating active forms of M.M.P. by photoaffinity labelling. Furthermore, as the new developed probe incorporated a radioactive element, photoaffinity labelling permitted to radiolabel the targeted proteins. This probe demonstrated in vitro its remarkable ability to covalently modify the h M.M.P.-12, with a singular cross-linking yield, determined at 42 %, displaying an extremely sensitive detection (2.5 fmoles of h M.M.P.-12). When added to complex proteome, the photoaffinity probe presents the same sensibility of detection for the h M.M.P.-12 (5 fmoles); importantly, in this case, h M.M.P.-12 represents only 0.001 % of the totality of the proteins present in the sample. Moreover, this technique allows

    Full Text Available Neste estudo foram realizados experimentos numéricos com um modelo meteorológico regional a fim de verificar o impacto dos Fluxos de Calor Latente (FCL e Calor Sensível (FCS em superfície no desenvolvimento de um ciclone intenso ocorrido sobre a costa leste da região sudeste da América do Sul, entre os dias 24 e 26 de julho de 1998. A taxa de intensificação do ciclone foi reduzida em 6 hPa/24 h no experimento em que os FCL e FCS estavam ausentes. Verificou-se que a ausência do FCL apresentou maior impacto do que a ausência do FCS, fazendo com que a taxa de intensificação fosse reduzida em 6 hPa/24 h para o experimento sem FCL e permanecesse inalterada sem FCS, mas neste último a isóbara de menor valor no centro do ciclone ocupou uma área menor. A ausência dos FCL e FCS em superfície gerou uma camada mais seca e mais fria próxima à superfície oceânica, reduzindo a instabilidade potencial do ambiente e diminuindo a intensificação do ciclone. Concluiu-se, portanto que os FCL e FCS em superfície foram importantes antes da fase de mais rápido desenvolvimento do ciclone, agindo no sentido de preparar o ambiente para uma ciclogênese mais intensa, através do fornecimento de energia e umidade para a baixa troposfera. Na fase de mais rápido desenvolvimento, a energia e a umidade disponíveis nas camadas mais baixas da atmosfera (inseridos na fase anterior também foram importantes, permitindo ao ciclone se desenvolver mais intensamente do que ocorreria em um ambiente mais seco e menos instável termicamente.Numeric experiments were run with meteorological regional model with the purpose to verify the impact of both latent and sensible surface heat fluxes (FCL and FCS, respectively during the development of an intense east cost cyclone over southeastern region of South America from 24 to 26 July, 1998.

  17. Energy and the environment: A sensible, no regrets'' proposal

    Energy Technology Data Exchange (ETDEWEB)

    Adler, J.H. (Competitive Enterprise Inst., Washington, DC (United States))

    America, it seems, uses too much energy. Thus, the government prepares to issue a new round of federal energy efficiency standards for all manner of household appliances. The Sierra Club insists that the federal government increase Corporate Average Fuel Economy (CAFE) standards for automobiles and trucks. Other groups push electric cars. The Clinton Administration, for its part, wants the federal government to subsidize the development and sale of alternative'' energy technologies, including solar panels, and is considering new regulations to drive down the use of fossil fuels. An energy tax was proposed five years ago, with little success, so this time other measures will be used to increase the cost of fuel and encourage Americans to do more with less. A virtually identical list of policy prescriptions was trotted out to address the threats of oil depletion, foreign oil dependence, and even global cooling. It seems no matter what the danger, the solution put forward by the environmental establishment is always the same: increase government control over the economy to drive down energy use. Those nations with the greatest governmental controls over their economy suffered the worst environmental catastrophes. Even in market-oriented economies, most major environmental problems can be traced to governmental subsidies or a failure to protect property rights and market institutions. It is time for environmental activists to learn that environmental protection does not require more government. In most instances, it would do better with less. A free-market no regrets'' policy would consist of the following three elements: (1) removing regulatory barriers to innovation; (2) eliminating subsidies to energy use; and (3) deregulating energy-related markets. The benefit of a no regrets policy is that it produces benefits whether or not the threat of climate change is real. Taxpayers benefit from reduced government spending, businesses benefit from reduced regulation, and they all benefit from the resulting increase in innovation and investment in dynamic sectors of the economy. And, if by some chance a greenhouse apocalypse comes true, a no regrets policy leaves us in a better position to address it. The choice is rather simple: adopt a policy that will impose substantial costs to address an uncertain threat or adopt a policy that pays off whether the world warms or not. For those truly concerned about human welfare, the choice should be clear.

  18. The use of antipsychotics in preschoolers: a veto or a sensible last option?

    Memarzia, Jessica; Tracy, Derek; Giaroli, Giovanni

    2014-04-01

    Recent reports have illustrated a dramatic rise in the use of antipsychotics in preschool children, medications originally designed and licensed for the treatment of adult psychotic disorders. Within this context, the current usage and the associated diagnoses are reviewed and compared with official guidelines and licensing for such use, highlighting a controversial challenge for clinicians. A review of the evidence base of the relative efficacy of such medications for a range of disorders is given. Associated safety and side effects are discussed, with compelling evidence for increased adverse events associated with use of antipsychotics in preschoolers, and neurodevelopmental hypotheses are used to guide predictions of long-term risk. An apparent gap in the literature and evidence base supporting such use and elucidating the risks and benefits leaves a challenge for clinicians and researchers and hinders the development of appropriate guidelines. Pragmatism in clinical practice, mindful of the limited evidence base that does exist and the propensity for harm, is necessary; far more research is required in this important area. PMID:24451556

  1. Sensibility of hydrous ethanol adulteration detection using ultrasonic parameters validated in a metrological base

    International Nuclear Information System (INIS)

    The aim of this study is to identify possible changes in fuels, in this case hydrous ethanol, through ultrasonic parameters such as attenuation and propagation speed. The system setup and method were implemented at Inmetro's Laboratory of Ultrasound. Experiments and method uncertainties were assessed accordingly to ISO/IEC Guide 98 1:2009 (Uncertainty of measurement - Part 1: Introduction to the expression of uncertainty in measurement). Mixtures of ethanol and water varying from 90% to 94% of alcohol in mass were used as testing samples. Attenuation and propagation speed were accurately measured and uncertainties evaluated. The accordingly to Brazilian biofuel regulations, the concentration of water in hydrous ethanol can be accepted at a maximum concentration of 93.8 and minimum of 92.6 of alcohol in mass. To achieve that figure, a functional combination of tested parameters should be implemented. Those results could be used as a tool to identify adulteration of biofuel, even in analysis performed on site.

    Full Text Available El ENaC es un canal que permite el movimiento de Na+ desde el líquido luminal hacia las células en numerosos epitelios reabsortivos y también en otros tejidos como la placenta. ENaC juega un papel crucial en la homeostasis de los electrolitos y volumen de líquido extracelular. Es regulado por numerosas hormonas, incluyendo la aldosterona y bloqueado por el diurético amiloride. El ENaC está formado por tres subunidades homólogas α, β y γ que forman el poro por el cual se mueven los iones Na+. Dos factores regulan la actividad del ENaC. 1 el número de canales insertos en la membrana celular y 2 la probabilidad de apertura o tiempo en que se encuentra abierto el canal. El número de canales es el resultado de un balance entre su síntesis y degradación. La probabilidad de apertura depende de la proteólisis de zonas específicas de las subunidades α y γ por múltiples proteasas dentro de la célula y en el espacio extracelular. Entre las proteasas más estudiadas se encuentran la furina, prostasina, elastasa, plasmina y tripsina. Existen sustancias endógenas que bloquean la actividad de estas proteasas como la aprotinina, la bikunina y la nexina-1 y la expresión de las proteasas y sus inhibidores es regulada a su vez por la aldosterona, la tasa de movimiento de Na y el TFGβ. En este trabajo presentamos algunos ejemplos de esta regulación y su potencial papel en condiciones normales y en ciertas enfermedades como la fibrosis quística, renales e hipertensión.

    Objective:To clarify the modulatory effects of daily consumption of pomegranate extract (PE), olive oil (OO) and Nagilla sativa oil (NSO) on antioxidant activity, sperm quality and pituitary-testicular axis of adult male wistar rats. Methods:Thirty-two adult male Wistar rats were divided into four equal groups, eight rats each. Using rat gastric tubes, 1.0 mL distilled water, 1.0 mL PE, 0.4 mL NSO and 0.4 mL OO were orally administered daily for 6 weeks in the first, second, third and fourth groups, respectively. Reproductive organs, body weight, sperm criteria, testosterone, FSH, LH, inhibin-B, lipid peroxidation, and antioxidant enzyme activities were investigated. At the end of the study protocol, analyses occurred at the same time. Data were analysed by ANOVA test and P<0.05 was considered to be a significant value. Results:In all studied groups, malondialdehyde level was significantly decreased accompanied with an increases in glutathione peroxidase and glutathione. Rats treated with PE showed an increase in catalase activities accompanied with an increase in sperm concentration which was also observed in NSO group. In PE treated group, sperm motility was also increased accompanied with decreased abnormal sperm rate. NSO, OO and PE treated groups shows an insignificant effect on testosterone, inhibin-B, FSH and LH in comparison with control group. Conclusions:These results show that administration of PE, NSO and OO could modify sperm characteristics and antioxidant activity of adult male wistar rats.

  6. Sensibility to Changes of Vibrational Modes of Excited Electron: Sum Frequency Signals Versus Difference Frequency Signals

    International Nuclear Information System (INIS)

    In this paper, we investigate a two electronic level system with vibrational modes coupled to a Brownian oscillator bath. The difference frequency generation (DFG) signals and sum frequency generation (SFG) signals are calculated. It is shown that, for the same model, the SFG signals are more sensitive than the DFG signals to the changes of the vibrational modes of the electronic two-level system. Because the SFG conversion efficiency can be improved by using the time-delay method, the findings in this paper predict that the SFG spectrum may probe the changes of the microstructure more effectively.

  8. Principal results of uncertainty and sensibility analysis for generic spanish AGP-granite

    International Nuclear Information System (INIS)

    Recently, ENRESA published his Performance Assessment of a deep geologic repository in granite. This paper summarises the main results of the uncertainty and sensitivity analysis performed on the data generated for the main scenario in the ENRESA Performance Assessment. The uncertainty analysis allowed us to determine the most important radionuclides, which were ''129I, ''36 Cl, ''79 Se and ''126 Sn, and to estimate upper bounds for the risk due to each one of them and for the global risk. Since ''129 I was the most important radionuclide, the main efforts in the sensitivity study were done in studying the most influential parameters on the maximum dose due to that radionuclide. The analysis shows that the order of magnitude of the maximum dose is essentially related to geosphere transport parameters. Nevertheless, the most influential parameters, when considering only the highest values of the maximum doses, are those that control the total amount of contaminant that can be driven into the main path to biosphere.

    Described is the technique of determination of nuclear photoemulsion absolute sensitivity for the case when ion beams used for sensitivity calibration have a complex distribution function over transverse constituents of the impulse. To obtain axial-symmetric image of the beam upon photoplate thin dispersing foils are used which permits to find the dependence of blackenning density on the density of the coming ion charge in the form of the solving of the Volterra equation of the first kind in the process of experimental data processing. Results of sensitivity measurements of the domestic photoplates of the MP type to the proton beams with the energy of 1.1 MeV obtained using linear resonance accelerator with alternating-phase focusing are given

  11. Temperature sensibility of the birefringence properties in side-hole photonic crystal fiber filled with Indium

    International Nuclear Information System (INIS)

    We report on the temperature sensitivity of the birefringence properties of a special kind of photonic crystal fiber containing two side holes filled with Indium metal. The modulation of the fiber birefringence is accomplished through the stress field induced by the expansion of the metal. Although the fiber was made at low gas pressures during the indium infiltration process, the birefringence showed anomalous property at a relatively low temperature value, which is completely different from those reported in conventional-like fibers with two holes filled with metal. By modeling the anisotropic changes induced by the metal expansion to the refractive index within the fiber, we are able to reproduce the experimental results. Our results have practical relevance for the design of devices based on this technology

  14. Improve accuracy and sensibility in glycan structure prediction by matching glycan isotope abundance

    International Nuclear Information System (INIS)

    Highlights: ► A glycan isotope pattern recognition strategy for glycomics. ► A new data preprocessing procedure to detect ion peaks in a giving MS spectrum. ► A linear soft margin SVM classification for isotope pattern recognition. - Abstract: Mass Spectrometry (MS) is a powerful technique for the determination of glycan structures and is capable of providing qualitative and quantitative information. Recent development in computational method offers an opportunity to use glycan structure databases and de novo algorithms for extracting valuable information from MS or MS/MS data. However, detecting low-intensity peaks that are buried in noisy data sets is still a challenge and an algorithm for accurate prediction and annotation of glycan structures from MS data is highly desirable. The present study describes a novel algorithm for glycan structure prediction by matching glycan isotope abundance (mGIA), which takes isotope masses, abundances, and spacing into account. We constructed a comprehensive database containing 808 glycan compositions and their corresponding isotope abundance. Unlike most previously reported methods, not only did we take into count the m/z values of the peaks but also their corresponding logarithmic Euclidean distance of the calculated and detected isotope vectors. Evaluation against a linear classifier, obtained by training mGIA algorithm with datasets of three different human tissue samples from Consortium for Functional Glycomics (CFG) in association with Support Vector Machine (SVM), was proposed to improve the accuracy of automatic glycan structure annotation. In addition, an effective data preprocessing procedure, including baseline subtraction, smoothing, peak centroiding and composition matching for extracting correct isotope profiles from MS data was incorporated. The algorithm was validated by analyzing the mouse kidney MS data from CFG, resulting in the identification of 6 more glycan compositions than the previous annotation and significant improvement of detection of weaker peaks compared with the algorithm previously reported.

    Processes of sensibilization and quenching of luminescence of iron and lanthanide ions in silicate glasses were investigated. It is shown that luminescence of examined iron-containing glasses is composed of a series of wide bands, conditioned by interconfigurational transition of Fe(2) ions, electron recombination with photoionized Fe(2)+ ions, as well as by decomposition of excited Fe(3) states. All three types of luminescence centers of iron-containing glasses participate in sensibilization of Nd(3), Er(3), Yb(3) luminescence

    Using a 2-D simulation model, the spreading of a passive solute is investigated varying the transversal distribution assumed for the diffusion coefficient and the velocity. Using strongly different laws, the simulation results show a larger influence on the dispersion process by the velocity distribution, while the influence of the diffusion coefficient distribution is very small, so that it is important just to catch the average value for this coefficient. Different transversal distributions of velocity produce values of maximum concentration with a scatter in the 30-40% range

  2. Sensibility of different Bragg curve profile in output energies of proton beams in heterogeneous targets

    International Nuclear Information System (INIS)

    Full text. In the recent years, the use of proton beams in radiotherapy has been an outstanding progress. Up to now, the CT is a requirement for treatment planning in this kind of therapy because it provides the electron density distribution required for dose and range calculations. However, the use of CT images for proton treatment planning ignores fundamental differences in physical interaction processes between photons and protons and is, therefore, potentially inaccurate. Proton CT (pCT) can in principle directly measure the density distribution needed in a patient for the dose distribution. One important problem that should be solved is the implementation of image reconstruction algorithms. In this sense, it is necessary to know how the presence of materials with different density and composition interfere in the energy deposition by ionization and coulomb excitation, during its trajectory. The study was conducted in two stages, in both SRIM and MCNPX codes were used to perform all simulations of the interaction of proton beams with pencil beam shape, for energies in the range from 100 to 250 MeV. The first part was used a target of 50 mm with a 6 mm layer of cortical bone (ICRP) and the rest of water. The bone's position was being varied in step of 5 mm. The second part the layer of bone was divided into two equal parts, placed at the ends of the target and were being approached in the same step of the first part. The obtained data were energy, position (X,Y,Z) for each axis that was used to obtain the averages, histograms and Gaussian such data for each position of heterogeneity. From these data, we have aimed at making a comparative analysis to study how the position of the heterogeneity influences on the energy and the feasibility of computer code for simulations more realistic.

The method is based on superimposing the multifractal structure of singularit...

  4. Sensibility analysis of Eu151 and Eu153 measured activation responses to cross section evaluation

    International Nuclear Information System (INIS)

    An international benchmark exercise was launched by ITER Joint Central Team for an experimental validation of the integral decay power heat for fusion relevant materials irradiated in 14 MeV neutron spectra. In this paper, we compare the results of JAERI/FNS decay heat experiments performed upon Eu203 sample with calculations done with the inventory code FISPACT-2005 using two different cross section evaluations for the isotope 151Eu and 153Eu, namely EAF-2005 and BRC6(CEA/DAM). In order to estimate the difference between the calculated and the experimental decay heat values and the impact on the calculation results by the two different activation libraries adopted in the present work, the percentage ratios (C-E)/E % have been deduced and are presented. The outcome is the validation of the BRCD6 europium activation nuclear data by the adopted computational approach which provides a better agreement with the experiment than the EAF one, despite a low energy neutron flux uncertainty.

  5. The aspects of deformation sensibility of SmCo5 phase

    International Nuclear Information System (INIS)

    The surface of Co100-xSmx (x=16.8, 17.1 at.%) samples of sintered magnets was polished by a number of different abrasive. The samples were examined by X-ray diffraction analysis (XRD) using CuKα radiation. XRD spectra were found to consist of two terms 1) a bulk SmCo5 term and 2) SmCo5 in deformed surface layer. For the last case the lattice parameters of hexagonal SmCo5 phase are increased significantly (up to values a = 0.5037 nm, c = 0.3999 nm). The parameter c is most sensitive to deformation. The broadening and displacement of reflections of XRD spectra of true bulk and surface distorted SmCo5 phases were analyzed. The lattice constants are measured to be a = 0.50022 nm, c = 0.39636 nm at x = 16.8 at.% and a = 0.50060 nm, c = 0.39633 nm at x = 17.1 at.% Sm. (orig.)

  6. Sensibility study for B → Invisible(+γ) decay with the BaBar detector

    International Nuclear Information System (INIS)

    We show prospects for research of invisible decays of B meson in a sample of about 470 millions BB pairs recorded with the BABAR detector at the SLAC PEP-II B factory. The Standard Model predictions for a B decay with completely invisible final products (or with a single photon as detectable particle) are far from the current experimental sensitivities but several New Physics Models predict significant enhancements on the branching ratio of these decays. The analysis technique consists in the reconstruction of a semileptonic B decay on one side and in the search of missing energy or missing energy plus one photon in the recoil. We will describe the search techniques and provide the expected sensitivities for these decays.

    The aim of this study is to identify possible changes in fuels, in this case hydrous ethanol, through ultrasonic parameters such as attenuation and propagation speed. The system setup and method were implemented at Inmetro's Laboratory of Ultrasound. Experiments and method uncertainties were assessed accordingly to ISO/IEC Guide 98 1:2009 (Uncertainty of measurement - Part 1: Introduction to the expression of uncertainty in measurement). Mixtures of ethanol and water varying from 90% to 94% of alcohol in mass were used as testing samples. Attenuation and propagation speed were accurately measured and uncertainties evaluated. The accordingly to Brazilian biofuel regulations, the concentration of water in hydrous ethanol can be accepted at a maximum concentration of 93.8 and minimum of 92.6 of alcohol in mass. To achieve that figure, a functional combination of tested parameters should be implemented. Those results could be used as a tool to identify adulteration of biofuel, even in analysis performed on site.

    Having in mind the objective of assessing the gamma radiation effect in two species of pseudo cereals, April 2012 to August 2013 in the National Institute of Nuclear Research Dr. Nabor Carrillo Flores, seeds from different collections of Amaranthus hypochondria cus and Chenopodium berlandieri nuttalliae, were subjected to different doses of irradiation (from 0 to 450 Gy, within an interval of 50 Gy) that were compared with a control of (0 Gy). For amaranth, the collection A1 showed the best feedback among 0 and 300 Gy in the 15 studied variables, the one that stood out was the 200 Gy doses in seed weight per plant (SWP) with 1.33 g. Huauzontle H3 to 50 Gy showed the best results for weight and seed diameter. High doses (from 300 to 450 Gy) showed higher percentage of mortality in spite of the fact that in some cases germination was stimulated. It is advisable for future studies about these pseudo cereals doses among 50 and 250 Gy. (Author)

  10. Conceptual analytical production of high power fuel and high fiber protein through sensible source

    International Nuclear Information System (INIS)

    Agricultural material (corn, wheat, barley, oat, rye and molasses) was subjected to fermentation to produce high fiber protein (HFP). Ethanol produced was further processed into high power alcohol and compared its characteristic properties with that of the natural fuel. The high power alcohol was transformed into high power fueld by the interaction of potassium salts of the derivative of carbohydrates with high power alcohol. The potassium salts of carbohydrate was prepared at two stages. The derivative so produced was treated with chlorosulphonic acid in presence of potassium carbonate to produce potassium salts of the derivative of carbohydrates. (Orig./A.B.)

    The aim of this study was to investigate the inter- and intra-tester reliability of the static two-point discrimination and Semmes-Weinstein monofilament tests in digital nerve repair. A total of 100 digital nerves from 67 patients were included into the study. An experienced orthopaedic surgeon and a physiotherapist examined the sensory nerve recovery. The reproducibility score of both tests was at a poor level, but the reliability of the Semmes-Weinstein monofilament test was higher than the static two-point discrimination test. These tests should not be used alone in the quantitative monitoring of sensory recovery, but should be interpreted with the clinical findings.Level 3 non-randomized controlled study. PMID:26685154

  15. Sensibility to Changes of Vibrational Modes of Excited Electron: Sum Frequency Signals Versus Difference Frequency Signals*

    2011-01-01

    In this paper, we investigate a two electronic level system with vibrational modes coupled to a Brownian oscillator bath. The difference frequency generation (DFG) signals and sum frequency generation (SFG) signals are calculated. It is shown that, for the same model, the SFG signals are more sensitive than the DFG signals to the changes of the vibrational modes of the electronic two-level system. Because the SFG conversion efficiency can be improved by using the time-delay method, the findings in this paper predict that the SFG spectrum may probe the changes of the microstructure more effectively.

    Highlights: Black-Right-Pointing-Pointer A glycan isotope pattern recognition strategy for glycomics. Black-Right-Pointing-Pointer A new data preprocessing procedure to detect ion peaks in a giving MS spectrum. Black-Right-Pointing-Pointer A linear soft margin SVM classification for isotope pattern recognition. - Abstract: Mass Spectrometry (MS) is a powerful technique for the determination of glycan structures and is capable of providing qualitative and quantitative information. Recent development in computational method offers an opportunity to use glycan structure databases and de novo algorithms for extracting valuable information from MS or MS/MS data. However, detecting low-intensity peaks that are buried in noisy data sets is still a challenge and an algorithm for accurate prediction and annotation of glycan structures from MS data is highly desirable. The present study describes a novel algorithm for glycan structure prediction by matching glycan isotope abundance (mGIA), which takes isotope masses, abundances, and spacing into account. We constructed a comprehensive database containing 808 glycan compositions and their corresponding isotope abundance. Unlike most previously reported methods, not only did we take into count the m/z values of the peaks but also their corresponding logarithmic Euclidean distance of the calculated and detected isotope vectors. Evaluation against a linear classifier, obtained by training mGIA algorithm with datasets of three different human tissue samples from Consortium for Functional Glycomics (CFG) in association with Support Vector Machine (SVM), was proposed to improve the accuracy of automatic glycan structure annotation. In addition, an effective data preprocessing procedure, including baseline subtraction, smoothing, peak centroiding and composition matching for extracting correct isotope profiles from MS data was incorporated. The algorithm was validated by analyzing the mouse kidney MS data from CFG, resulting in the identification of 6 more glycan compositions than the previous annotation and significant improvement of detection of weaker peaks compared with the algorithm previously reported.

  20. Design of nuclear fuel cells by means of a statistical analysis and a sensibility study

    International Nuclear Information System (INIS)

    This work contains the results of the statistical analysis realized to study the nuclear fuel cells performance, considering the frequencies for the election of fuel bars used in the design of the same ones. The election of the bars used for the cells design are of 3 types, the first election shows that to the plotting the respective frequency is similar to a normal distribution, in the second case the frequencies graph is of type inverted square X2 and the last election is when the bars are chosen in aleatory form. The heuristic techniques used for the cells design were the neural networks, the ant colonies and a hybrid between the dispersed search and the trajectories re-linkage. To carry out the statistical analysis in the cells design were considered the local power peak factor and the neutron infinite multiplication factor (k∞) of this. On the other hand, the performance of the designed cells was analyzed when verifying the position of the bars containing gadolinium. The results show that is possible to design cells of nuclear fuel with a good performance, when considering the frequency of the bars used in their design. (Author)

  2. Sense or Sensibility?: How Commitment Mediates the Role of Self-Service Technology on Loyalty

    Science.gov (United States)

    Singh, Sangeeta; Olsen, Line Lervik

    It has been well documented that employing self-service technology (SST) results in considerable cost savings but few studies have examined its impact on consumers’ behavior. We apply a well-recognized model from the field of services marketing in an SST context. We examine how the established relationships between satisfaction, affective and calculative commitments, and loyalty are affected when the service is provided through a technology interface as opposed to service personnel. We then present two alternative perspectives on the role of SST. The first is based on the predominant assumption that SST is a moderator of the relationship between customer loyalty and its drivers, while the other rests on the assumption that SST is just another context and that its role in affecting customer loyalty is mediated by drivers of loyalty. A cross-sectional study conducted in the banking industry shows that SST does not change everything. The classical model of how customers evaluate services and the predictors of loyalty are replicated in the SST setting. Interestingly, SST does not have a direct influence on loyalty by itself but its effects are mediated by commitment. However, it is the affective commitment that is more important in forming loyalty toward the service provider.

  3. Sensibility and specificity of the stress echocardiography with Dobutamine for the detection of coronary disease

    International Nuclear Information System (INIS)

    Dobutamine stress echocardiography has become a useful method for detecting coronary artery disease in the high prevalence population. The reported sensitivity varies between 76-90% and the specificity between 60-95%. 60-95% there have been few reports regarding sensitivity and specificity among our population. The aim of this study was to evaluate the sensitivity of dopamine stress echocardiography in a population with a high probability of coronary disease. This was a randomized retrospective-prospective study. Between February 1 of 1998 and February 1 of 1999. 409 patients underwent dopamine stress echocardiography and were analyzed according to established protocol. The Dobutamine stress echocardiography as well as the angiography was checked in a blind form by one of the participating researchers trained in those procedures. The diagnostic concordance was found to be greater than 90%. Significant coronary disease was considered to be present in those cases in which there was severe stenosis greater than 50% in a major epicardial artery or greater than 40 % in the left main artery. Coronary arteriography was performed within three months of Dobutamine stress echocardiography imaging. A sixteen-segment model was used as the index for the evaluation of systolic wall thickening and the results were classified as follows: normal (l), ischemia (ll), fixed abnormality (lll) and mixed (lV). 409 patients with an average age of 62.8 +/- 12) were included in the study at random. Six patients with mediocre technical examinations were excluded. 47 % were male. 29% had a history of myocardial infarction, 35 % had a history of arterial hypertension and 10% had diabetes mellitus. The average ejection fraction was 54 +/- 13%. The examination was prescribed in order to detect the presence of ischemia in 95.8% of the cases and as part of preoperative evaluation in 4.2 %. There were adverse effects in 40% of the cases; 15% of these were systemic and 25 % cardiac. The test was suspended due to reaching the maximum heart rate

  4. Improvements in the sensibility of MSA-GA tool using COFFEE objective function

    International Nuclear Information System (INIS)

    The sequence alignment is one of the most important tasks in Bioinformatics, playing an important role in the sequences analysis. There are many strategies to perform sequence alignment, since those use deterministic algorithms, as dynamic programming, until those ones, which use heuristic algorithms, as Progressive, Ant Colony (ACO), Genetic Algorithms (GA), Simulated Annealing (SA), among others. In this work, we have implemented the objective function COFFEE in the MSA-GA tool, in substitution of Weighted Sum-of-Pairs (WSP), to improve the final results. In the tests, we were able to verify the approach using COFFEE function achieved better results in 81% of the lower similarity alignments when compared with WSP approach. Moreover, even in the tests with more similar sets, the approach using COFFEE was better in 43% of the times

    Due to family planning, Dutch women are increasingly having their first child between 25 and 35 years of age. Compared to 13 other EU countries, Dutch women are having fewer children both earlier and later on in life. From 1970 onwards in the Netherlands, the mean age at first childbirth has increased by 5 years to 29.4 years. The main cause for the rising age at first childbirth is the decrease in the number of young mothers. In 2006, 7% of all childbearing women had their first child after the age of 36; this is just 4.7% higher than in 1970. The percentage of women remaining childless by delaying childbearing too long increased by 0.9%. Considering the social and medical problems in later life, it would not be wise to encourage women to have their babies at a young age, certainly not before the age of 23. Women planning a family should take into account the decline in natural fertility after the age of 35; the future mothers of the Netherlands seem to be planning and deciding wisely. PMID:18681359

  6. Sense and Sensibility – Reflections on the Epistemology and Ontology of GIS Studies

    2004-11-01

    Full Text Available This article discusses the relationship between philosophy, archaeological theory and the use of GIS. It is argued that although specific theoretical issues have been discussed, epistemological and ontological questions with regard to the characteristics of data and data processing have not been subjected to rigorous theoretical critique. This is essential to understand the archaeological and non-archaeological qualities of data formats and GIS procedures. I am not alone in arguing that GIS has to be integrated into every research process in order to answer archaeological questions and that the results have to be interpreted according to a set archaeological theoretical framework. If the archaeological research process follows the principles of Bhaskar's realistic philosophy the critical application of the method is a natural consequence. It is also argued that the combination of realistic and pragmatic frameworks allows, theoretically, all critical use of archaeological GIS applications. Furthermore, the integration of post-structural ideas is shown to be crucial in the explanation of results provided by GIS modelling.

    Chronic wounds cost the Australian health system at least US$2·85 billion per year. Wound care services in Australia involve a complex mix of treatment options, health care sectors and funding mechanisms. It is clear that implementation of evidence-based wound care coincides with large health improvements and cost savings, yet the majority of Australians with chronic wounds do not receive evidence-based treatment. High initial treatment costs, inadequate reimbursement, poor financial incentives to invest in optimal care and limitations in clinical skills are major barriers to the adoption of evidence-based wound care. Enhanced education and appropriate financial incentives in primary care will improve uptake of evidence-based practice. Secondary-level wound specialty clinics to fill referral gaps in the community, boosted by appropriate credentialing, will improve access to specialist care. In order to secure funding for better services in a competitive environment, evidence of cost-effectiveness is required. Future effort to generate evidence on the cost-effectiveness of wound management interventions should provide evidence that decision makers find easy to interpret. If this happens, and it will require a large effort of health services research, it could be used to inform future policy and decision-making activities, reduce health care costs and improve patient outcomes.

    Directory of Open Access Journals (Sweden)

    Cary N. Weiss

    2015-03-01

    Full Text Available In the adult, the source of functionally diverse, mature blood cells are hematopoietic stem cells, a rare population of quiescent cells that reside in the bone marrow niche. Like stem cells in other tissues, hematopoietic stem cells are defined by their ability to self-renew, in order to maintain the stem cell population for the lifetime of the organism, and to differentiate, in order to give rise to the multiple lineages of the hematopoietic system. In recent years, increasing evidence has suggested a role for the accumulation of reactive oxygen species and DNA damage in the decision for hematopoietic stem cells to exit quiescence and to differentiate. In this review, we will examine recent work supporting the idea that detection of cell stressors, such as oxidative and genetic damage, is an important mediator of cell fate decisions in hematopoietic stem cells. We will explore the benefits of such a system in avoiding the development and progression of malignancies, and in avoiding tissue exhaustion and failure. Additionally, we will discuss new work that examines the accumulation of DNA damage and replication stress in aging hematopoietic stem cells and causes us to rethink ideas of genoprotection in the bone marrow niche.

    About 30% of horticultural crops grown in developing countries like India (38.77 million tonnes amounting to US $13 billion), get wasted annually due to gaps in Cold Chain like insufficient cold storage capacity, unavailability of cold storages in close proximity to farms, poor transportation infrastructure etc. With solar energy availability (Insolation) averaging 5.0 KWh/sq. m/day with 3000 hours of sunshine every year, about 30-35% of these losses can be reduced by transporting the freshly harvested produce to the cold storages in 40,000 TEUs of refrigerated containers with 5 million sq. ft. of solar PV panels fixed on their rooftops and sides.

    Voice over Internet protocol (VoIP) is a revolutionary new technology that is causing a stir in the telecommunications industry and threatening the existence of traditional telephone service providers. Based on a simple method of converting analog audio signals into digital data before being transmitted over the Internet, VoIP has gained immense popularity among consumers. The technology is now regarded as an alternative to traditional telephone service for the orthodontic office. When the economics are considered, it is cost-effective, especially for a busy orthodontic practice where the call volumes both in and out are always high. VoIP has the potential to reduce costs, break the barriers between local vs long-distance calling, and make life easier for the office staff. However, deploying VoIP requires a cautious and thought-out process. Users should fully understand the risks and benefits before switching from the public switched telephone network. VoIP customers and service providers are vulnerable to many of the same impersonation-based attacks by those who attempt toll fraud, and identity and information theft. In this article, VoIP is introduced to orthodontic practitioners, who might be unfamiliar with this technology. Internet protocol based private branch exchange systems that are currently marketed as open-source technologies are also reviewed. Additionally, VoIP is compared with the traditional public switched telephone network technology and evaluated for its potential applications in an orthodontic office for both increased efficiency and cost savings.

    Previous experimental studies on electromagnetic hypersensitivity have been criticized regarding inflexibility of choice of exposure and of study locations. We developed and tested novel portable exposure units that can generate different output levels of various extremely low frequency magnetic fields (ELF-MF; 50 Hz field plus harmonics) and radiofrequency electromagnetic fields (RF-EMF). Testing was done with a group of healthy volunteers (n = 25 for 5 ELF-MF and n = 25 for 5 RF-EMF signals) to assess if units were indeed able to produce double-blind exposure conditions. Results substantiated that double-blind conditions were met; on average participants scored 50.6% of conditions correct on the ELF-MF, and 50.0% on the RF-EMF unit, which corresponds to guessing probability. No cues as to exposure conditions were reported. We aim to use these units in a future experiment with subjects who wish to test their personal hypothesis of being able to sense or experience when being exposed to EMF. The new units allow for a high degree of flexibility regarding choice of applied electromagnetic signal, output power level and location (at home or another environment of subjects' choosing).

  7. Towards sensible toxicity testing for nanomaterials: proposal for the specification of test design

    2015-12-01

    During the last decade, nanomaterials (NM) were extensively tested for potential harmful effects towards humans and environmental organisms. However, a sound hazard assessment was so far hampered by uncertainties and a low comparability of test results. The reason for the low comparability is a high variation in the (1) type of NM tested with regard to raw material, size and shape and (2) procedures before and during the toxicity testing. This calls for tailored, nanomaterial-specific protocols. Here, a structured approach is proposed, intended to lead to test protocols not only tailored to specific types of nanomaterials, but also to respective test system for toxicity testing. There are existing standards on single procedures involving nanomaterials, however, not all relevant procedures are covered by standards. Hence, our approach offers a detailed way of weighting several plausible alternatives for e.g. sample preparation, in order to decide on the procedure most meaningful for a specific nanomaterial and toxicity test. A framework of several decision trees (DT) and flow charts to support testing of NM is proposed as a basis for further refinement and in-depth elaboration. DT and flow charts were drafted for (1) general procedure—physicochemical characterisation, (2) choice of test media, (3) decision on test scenario and application of NM to liquid media, (4) application of NM to the gas phase, (5) application of NM to soil and sediments, (6) dose metrics, (S1) definition of a nanomaterial, and (S2) dissolution. The applicability of the proposed approach was surveyed by using experimental data retrieved from studies on nanoscale CuO. This survey demonstrated the DT and flow charts to be a convenient tool to systematically decide upon test procedures and processes, and hence pose an important step towards harmonisation of NM testing.

    Full Text Available The present article presents a doctoral investigation. It mainly focuses on an action research whose problematic is based on the search for didactic-pedagogical paths which contribute to intercultural openness and change within schools allowing for better social integration. We have chosen the trilogy music, arts education and interculturality to address the central problematics of this research. Therefore an Intercultural Musical Program was conceived, implemented and assessed in three Portuguese Elementary/Preparatory schools. The main leading forces guiding this Program are attached to four areas, which constitute the theoretical/conceptual frame of this research: • Artistic education as a priority in education; • Intercultural education as a response to a growing cultural diversity; • The role of music as an harnessing methodology for intercultural communication; • Arts Programs as globalising impulses for human development and the preservation of cultural heritage. The empirical work rests on a methodology of qualitative analysis based on Renald Legendre’s (1993, 2005 model of Pedagogical Relationship (PR, combined with a strong influence of Visual Anthropology. The attained results are indicators of the high relevance and participation, as well as of the transforming impact of this action research, as a facilitator of intercultural communication and education among communities.

    Recently, environmental pollution is social problem with nano materials and food contamination is a new social problem. On the other hand, the complaint related to the offensive odor in Japan exceeded 20,000 affairs in 1998, and these problems are not solved. The odor sensing system for detecting and control an offensive odor at an early stage is required. The sensing system using the sense of odor known as one of the fifth senses of human is proposed to these demands. Especially as for e-NOSE system, application will be expected from now on in many fields, such as medical diagnosis, health monitoring, environment, food, robot and a car. The sensing technology in which an electrochemical sensor called quartz crystal microbalance (QCM) is mainly used is making detection mechanisms, such as an electrode and a detection thin film on the nano-level. Therefore, detection films of sensor depend on the characteristic of the sensing devices using on material and processing technology. That the new technology sensor is asked can detect extremely low concentration from ppm to ppb level, and it is the sensor with low influence of environment, such as a gas of the outside for detection, temperature and humidity.

  16. Is it sensible to “deform” dose? 3D experimental validation of dose-warping

    International Nuclear Information System (INIS)

    Purpose: Strategies for dose accumulation in deforming anatomy are of interest in radiotherapy. Algorithms exist for the deformation of dose based on patient image sets, though these are sometimes contentious because not all such image calculations are constrained by physical laws. While tumor and organ motion has been a key area of study for a considerable amount of time, deformation is of increasing interest. In this work, we demonstrate a full 3D experimental validation of results from a range of dose deformation algorithms available in the public domain. Methods: We recently developed the first tissue-equivalent, full 3D deformable dosimetric phantom—“DEFGEL.” To assess the accuracy of dose-warping based on deformable image registration (DIR), we have measured doses in undeformed and deformed states of the DEFGEL dosimeter and compared these to planned doses and warped doses. In this way we have directly evaluated the accuracy of dose-warping calculations for 11 different algorithms. We have done this for a range of stereotactic irradiation schemes and types and magnitudes of deformation. Results: The original Horn and Schunck algorithm is shown to be the best performing of the 11 algorithms trialled. Comparing measured and dose-warped calculations for this method, it is found that for a 10 × 10 mm2 square field, γ3%/3mm= 99.9%; for a 20 × 20 mm2 cross-shaped field, γ3%/3mm= 99.1%; and for a multiple dynamic arc (0.413 cm3 PTV) treatment adapted from a patient treatment plan, γ3%/3mm= 95%. In each case, the agreement is comparable to—but consistently ∼1% less than—comparison between measured and calculated (planned) dose distributions in the absence of deformation. The magnitude of the deformation, as measured by the largest displacement experienced by any voxel in the volume, has the greatest influence on the accuracy of the warped dose distribution. Considering the square field case, the smallest deformation (∼9 mm) yields agreement of γ3%/3mm= 99.9%, while the most significant deformation (∼20 mm) yields agreement of γ3%/3mm= 96.7%. Conclusions: We have confirmed that, for a range of mass and density conserving deformations representative of those observable in anatomical targets, DIR-based dose-warping can yield accurate predictions of the dose distribution. Substantial differences can be seen between the results of different algorithms indicating that DIR performance should be scrutinized before application todose-warping. We have demonstrated that the DEFGEL deformable dosimeter can be used to evaluate DIR performance and the accuracy of dose-warping results by direct measurement.

    Coastal dunes have an important function as unique habitats for plants and animals as well as natural barriers against storm tides. Thus, they are of special value for nature conservation and coastal defence issues. Facing their potential endangering due to accelerated climate change profound knowledge of stabilty of coastal dunes is essential. In this context the presented study deals with the impact of climate change on biogenic sand stabilization in coastal dunes, which have to be conceived as an ecosystemic process. Questions of climate affected reactions of organism groups involved in this process (plants, soil microflora, soil fauna) and alterations in soil structure were followed up. Within the scope of a 2-years-lasting field experiment conducted on the Eastfrisian Island Norderney the microclimate near the soil surface was modified by gauze covering, which was set up on field plots. (orig.) [German] In ihrer Funktion als Lebensraum fuer Pflanzen und Tiere sowie als natuerlicher Schutzwall bei Sturmfluten wird den Kuestenduenen eine wichtige Bedeutung im Natur- und Kuestenschutz beigemessen. Angesichts ihrer potentiellen Gefaehrdung durch einen beschleunigten Klimawandel ist ein fundierter Kenntnisstand zur Stabilitaet von Kuestenduenen von elementarem Interesse. Vor diesem Hintergrund befasst sich die vorliegende Studie mit dem Einfluss von Klimaaenderungen auf die biogene Sandstabilisierung in Kuestenduenen, die aufgrund des bestehenden organismischen Beziehungsgeflechtes als oekosystemarer Prozess aufzufassen ist. Dabei wurden Fragen nach klimaabhaengigen Reaktionen der an diesem Prozess beteiligten Organismengruppen (Pflanzen, Bodenmikroflora, Bodenfauna) und Veraenderungen des Bodengefueges bearbeitet.

  17. Realities of weather extremes on daily life in urban India - How quantified impacts infer sensible adaptation options

    Emerging and developing economies are currently undergoing one of the profoundest socio-spatial transitions in their history, with strong urbanization and weather extremes bringing about changes in the economy, forms of living and living conditions, but also increasing risks and altered social divides. The impacts of heat waves and strong rain events are therefore differently perceived among urban residents. Addressing the social differences of climate change impacts1 and expanding targeted adaptation options have emerged as urgent policy priorities, particularly for developing and emerging economies2. This paper discusses the perceived impacts of weather-related extreme events on different social groups in New Delhi and Hyderabad, India. Using network statistics and scenario analysis on Fuzzy Cognitive Maps (FCMs) as part of a vulnerability analysis, the investigation provides quantitative and qualitative measures to compare impacts and adaptation strategies for different social groups. Impacts of rain events are stronger than those of heat in both cities and affect the lower income classes particularly. Interestingly, the scenario analysis (comparing altered networks in which the alteration represents a possible adaptation measure) shows that investments in the water infrastructure would be most meaningful and more effective than investments in, e.g., the traffic infrastructure, despite the stronger burden from traffic disruptions and the resulting concentration of planning and policy on traffic ease and investments. The method of Fuzzy Cognitive Mapping offers a link between perception and modeling, and the possibility to aggregate and analyze the views of a large number of stakeholders. Our research has shown that planners and politicians often know about many of the problems, but are often overwhelmed by the problems in their respective cities and look for a prioritization of adaptation options. FCM provides this need and identifies priority adaptation options when resources are scarce. 1 Parry ML, Canziani OF, Palutikof JP, van der Linden PJ, Hanson CE (eds) (2007) Contribution of Working Group II to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change.

    The electronic instrumentation is indispensable for the measurement and characterization of the radiation. By means of this essential characteristics of the radiation are determined, as activity and their energy components. The nuclear instrumentation is based on the technical characteristics of the radiation detectors and the electronic devices associates (amplifiers, ana logical and digital converters, multichannel analyzers, etc.) The radiation detectors are very important instruments in fields as the nuclear physics, medicine, radiological protection, industry and in other fields, since they are the only method to capture the radiation and to be able to quantify it in precise form. To detect radiation diverse detector types are used, as the semiconductor type, inside them are the photodiodes type Pin. In this work the results that were obtained of the design, simulation, construction and tests of a preamplifier that was designed starting from a photodiode type Pin are presented. The system was designed and simulated with a program for electronic circuits, in this were carried out many tests being obtained a compact design and achieving the best necessary characteristics for its optimization. With the results of the simulation phase the electronics phase was built, which was couples to a spectroscopic amplifier and a multichannel analyzer. The total of the system was evaluated analyzing its performance before a triple source of alphas. Of the tests phase we find that the system allows obtaining, in a multichannel analyzer, the pulses height spectrum, with a good resolution and with this was calibrated the multichannel analyzer.

    The diurnal and vertical variability of heat and carbon dioxide (CO2) in the atmospheric surface layer are studied by analyzing measurements from a 213 in tower in Cabauw (Netherlands). Observations of thermodynamic variables and CO2 mixing ratio as well as vertical profiles of the turbulent fluxes are used to retrieve the contribution of the budget terms in the scalar conservation equation. On the basis of the daytime evolution of turbulent fluxes, we calculate the budget terms by assuming that turbulent fluxes follow a linear profile with height. This assumption is carefully tested and the deviation ftom linearity is quantified. The budget calculation allows us to assess the importance of advection of heat and CO2 during day hours for three selected days. It is found that, under nonadvective conditions, the diurnal variability of temperature and CO2 is well reproduced from the flux divergence measurements. Consequently, the vertical transport due to the turbulent flux plays a major role in the daytime evolution of both scalars and the advection is a relatively small contribution. During the analyzed days with a strong contribution of advection of either heat or carbon dioxide, the flux divergence is still an important contribution to the budget. For heat, the quantification of the advection contribution is in close agreement with results from a numerical model. For carbon dioxide, we qualitatively corroborate the results with a Lagrangian transport model. Our estimation of advection is compared with, traditional estimations based on the Net Ecosystem-atmosphere Exchange (NEE). Copyright 2008 by the American Geophysical Union.

  4. Seasonal hypoxia in eutrophic stratified coastal shelves: mechanisms, sensibilities and interannual variability from the North-Western Black Sea case

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available The Black Sea north-western shelf (NWS is a~shallow eutrophic area in which seasonal stratification of the water column isolates bottom waters from the atmosphere and prevents ventilation to compensate for the large consumption of oxygen, due to respiration in the bottom waters and in the sediments.

    A 3-D coupled physical biogeochemical model is used to investigate the dynamics of bottom hypoxia in the Black Sea NWS at different temporal scales from seasonal to interannual (1981–2009 and to differentiate the driving factors (climatic versus eutrophication of hypoxic conditions in bottom waters.

    Model skills are evaluated by comparison with 14 500 in-situ oxygen measurements available in the NOAA World Ocean Database and the Black Sea Commission data. The choice of skill metrics and data subselections orientate the validation procedure towards specific aspects of the oxygen dynamics, and prove the model's ability to resolve the seasonal cycle and interannual variability of oxygen concentration as well as the spatial location of the oxygen depleted waters and the specific threshold of hypoxia.

    During the period 1981–2009, each year exhibits seasonal bottom hypoxia at the end of summer. This phenomenon essentially covers the northern part of the NWS, receiving large inputs of nutrients from the Danube, Dniestr and Dniepr rivers, and extends, during the years of severe hypoxia, towards the Romanian Bay of Constanta.

    In order to explain the interannual variability of bottom hypoxia and to disentangle its drivers, a statistical model (multiple linear regression is proposed using the long time series of model results as input variables. This statistical model gives a general relationship that links the intensity of hypoxia to eutrophication and climate related variables.

    The use of four predictors allows to reproduce 78% of hypoxia interannual variability: the annual nitrate discharge (N, the sea surface temperature in the month preceding stratification (T, the amount of semi-labile organic matter in the sediments (C and the duration of the stratification (D. Eutrophication (N, C and climate (T, D predictors explain a similar amount of variability (~35% when considered separately. A typical timescale of 9.3 yr is found to describe the inertia of sediments in the recovering process after eutrophication.

    From this analysis, we find that under standard conditions (i.e. average atmospheric conditions, sediments in equilibrium with river discharges, the intensity of hypoxia can be linked to the level of nitrate discharge through a non-linear equation (power law.

    Bottom hypoxia does not affect the whole Black Sea NWS but rather exhibits an important spatial variability. This heterogeneous distribution, in addition to the seasonal fluctuations, complicates the monitoring of bottom hypoxia leading to contradictory conclusions when the interpretation is done from different sets of data. We find that it was the case after 1995 when the recovery process was overestimated due to the use of observations concentrated in areas and months not typically affected by hypoxia. This stresses the urging need of a dedicated monitoring effort in the NWS of the Black Sea focused on the areas and the period of the year concerned by recurrent hypoxic events.

  6. CT colonoscopy: sensibility in 2D/4D CT colonoscopy versus virtual endoscopy. Correlation to conventional colonoscopy

    International Nuclear Information System (INIS)

    Colorectal carcinoma is the second leading cause of death from malignant tumors. Most large bowel malignancies arise from pre-existing adenomas. In individual older than 50 years the prevalence of polyps and cancer increases. Therefore screening is recommended for average risk individuals in this group. Recently a new technique called 'Virtual Colonoscopy' has appeared. The purpose of this study was to compare the diagnosis accuracy of two dimensional CT Colonoscopy (2D CTC) and Virtual Colonoscopy (VC) individually with Conventional Colonoscopy (CC) and to determine improvement of the Sensitivity (S) and Specificity (E) combining both types of evaluation. Ninety patients were studied (47 women and 43 men). CT studies were obtained on a helical CT scanner. The lesions were studied in supine and prone position. All patients had CC done within 10 hours before CTC. The lesions were divided in 3 groups: 1) 9 mm. Each group was divided into 3 subgroups: a) findings in 2D; b) findings in VC; and c) findings combined. Ninety-two lesions were identified on CC and 101 on CTC. There were 9 false positive in all groups. The statistical analysis showed a high S and E in both 2D and VC. The combination of both methods does not increase significantly the diagnosis of CTC but the S reached 100% because the false negative rate was reduced to 0. (author)

    Full Text Available  Background & Objective: Urinary infection is one of the most prevalent infectious diseases, and Escherichia coli is the most important cause of urinary infections. This study was done with the aim of surveying the amount of susceptibility and resistance among the strains of Escherichia coli isolated from those who referred to the private laboratories in the Iranian city of Tabriz.   Materials & Methods: This survey was done periodically during the first 6 months of the year 2010. Samples were obtained in a sterile manner and were subjected to all necessary pathological tests. Evaluation of antibiotic susceptibility was conducted with disk diffusion standard method, and the results were analyzed.   Results: Totally, 5701 Escherichia coli strains were identified. The highest sensitivity to Imipenem was 90.95%, Nitrofurantoin 85.97%, and Cefotaxime 71.02% and the highest resistance to Ampicillin was 83.95%, Tetracycline 80.97%, and Co-trimoxazole 63.92%.   Conclusion: Our results suggest that the cause of the high resistance of Escherichia coli strains to Ampicillin and Tetracycline could be the consumption of these antibiotics. Therefore, abstaining from overuse of unnecessary antibiotics and production of new-generation and cost-effective antibiotics are recommend.

  12. Central sensibility of human cases with different body mass during oral glucose tolerance test using functional magnetic resonance imaging

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    BACKGROUND: Because of the limitation of technique, there are few researches on regulating function of central hypothalamus by metabolism, especially the researches on real-time function.OBJECTIVE: To evaluate the response of hypothalamus to oral glucose tolerance test (OGTT) in different body-weighted subjects by using functional magnetic resonance imaging (fMRI) so as to investigate the relationship between the sensitivity of hypothalamus in glycoregulation and disturbance of carbohydrate metabolism.DESIGN: Paired design.SETTING: Department of Radiology and Beijing Geriatrics Institute, Beijing Hospital, National Public Health Bureau.PARTICIPANTS: A total of twenty healthy volunteers were selected from Beijing Geriatrics Institute,National Public Health Bureau, including 10 subjects with obesity (5 males and 5 females; body mass >28.0 kg/m2) and 10 subjects with normal body mass (5 males and 5 females; body mass from 18.5 to 23.9 kg/m2). All subjects gave written informed consent before participating in the study.METHODS: fMRI study was performed on GE 1.5 T Signa Twinspeed Infinity with Excite. Each volunteer was ingested of glucose during the fMRI scan. T2* images were acquired using a single-shot gradient echo (EPI) technique. The parameters of EPI included: TR 3 000 ms, TE 40 ms, Flip angle 90 ° , field of view (FOV) 24 cm × 24 cm, thickness 5 mm, gap 0 mm, matrix 64 × 64, number of excitation 1. All 10 subjects with normal body mass underwent a repeat fMRI scan after consuming an equivalent amount of water without glucose on a separate day. The procedure for the fMRI scan with water intake was the same as for glucose ingestion. fMRI data were processed with Intensity Averaging Method.MAIN OUTCOME MEASURES: The central response of hypothalamus and feedback orientation during OGTT in different body-weighted subjects.RESULTS: An acute transient decrease of fMRI intensity in posterior inferior and anterior inferior of hypothalamus was observed in all subjects within 2 minutes after oral glucose intake. This decrease was followed by a recovery to the baseline. However, obese subjects had a delayed intensity decrease [(1.96±1.06) minutes vs. (1.04±0.71) minutes, t =2.14, P < 0.05] and longer recovery time [(26.62±7.35)minutes vs. (16.29±6.42) minutes, t =3.67, P < 0.01] as compared with normal body-weight subjects. Furthermore, decreased fMRI intensity was significant different from baseline intensity [(5.7±2.5)% vs.(14.3±5.5)%, t =2.56, P < 0.05] in obese subjects, but not in normal body-weight subjects. The area of hypothalamus in normal body-weight volunteers demonstrated no significant signal change before and after oral water ingestion (P > 0.05).CONCLUSION: Hypothalamus response to glucose loading is different in normal body-weighted and obese subjects. This suggests that fMRI is a useful tool to evaluate the central regulation of glucose metabolism.

  13. A sensibility study of the piping spans following the weight variations of the in-line components

    International Nuclear Information System (INIS)

    Piping systems in nuclear power plants are composed of piping and in-line components such as flanges, valves, insulations, etc. Piping analyses including dead weight and seismic analyses are based on the weights and locations of these piping components. Frequently, due to various material changes, site, and construction problems, piping design changes are inevitable after piping drawings were issued for construction. These design changes could lead to serious impact on cost and schedule. As such, site engineers must react quickly based on experiences to make the correct decision to mitigate the problems with construction costs and schedule. This paper provides simple equations for rapid span-checks to determine if the changes are deemed acceptable instead of undertaking time-consuming detailed analyses which take long time to complete. These simple span-check equations are derived from the sensitivity analysis of piping spans through variation of masses, sizes, and locations of in-line components. The criteria used in deriving the simple span-check equations are based on the acceptable deflections and stresses of various pipe sizes used in APR1400 (Korea's Advanced Power Reactor 1400 MWe class). The results show that the simple span-check equations derived herein can be a useful tool for site engineers to respond to frequent design change requests. (authors)

    Full Text Available O cancro cítrico, causado por Xanthomonas axonopodis pv. citri (Xac é uma das principais doenças na produção de citros em diversas regiões do mundo. A aplicação de produtos químicos com ação bactericida é uma das principais medidas adotadas para o controle dessa doença. O objetivo deste estudo foi determinar a sensibilidade de isolados Xac ao cobre, bem como à mistura de cobre com mancozeb. A maior concentração de cobre em que foi observado crescimento de isolados de Xac foi de 50 µg/mL. Entretanto, 45,5 % dos isolados da bactéria provenientes de pomares que receberam aplicações freqüentes de cobre cresceram na presença de 50 µg/mL de cobre, contra apenas 13,4 % dos isolados oriundos de pomares que não receberam pulverizações regulares do bactericida. A presença de mancozeb em mistura com cúpricos reduziu a sensibilidade ao cobre dos isolados de Xac. Desta forma, o mancozeb não deve ser utilizado em mistura com cobre para o controle do cancro cítrico.Citrus canker, caused by Xanthomonas axonopodis pv. citri (Hasse Vauterin et al. 1995 (Xac, is one of the most important problems for citrus production around the world. Spraying with copper compounds is a major measure for control of the disease. The objective of this study was to determine the sensitivity of Xac strains from the State of Parana, Brazil, to copper as well as to a mixture of copper with mancozeb. The highest copper concentration where Xac grew was 50 µg/mL. However, 45.5 % of the bacterial strains from orchards with regular sprays of copper compounds grew in the presence of 50 µg/mL of copper. In contrast, only 13.4 % of the strains from citrus orchards that never received copper sprays grew in such a copper concentration . Mixing mancozeb with copper increased the tolerance of Xac to copper. Therefore, the recommendation of mancozeb mixed with copper for control of the citrus canker bacterium should be reviewed.

    International Nuclear Information System (INIS)

    The diurnal and vertical variability of heat and carbon dioxide (CO2) in the atmospheric surface layer are studied by analyzing measurements from a 213 m tower in Cabauw (Netherlands). Observations of thermodynamic variables and CO2 mixing ratio as well as vertical profiles of the turbulent fluxes are used to retrieve the contribution of the budget terms in the scalar conservation equation. On the basis of the daytime evolution of turbulent fluxes, we calculate the budget terms by assuming that turbulent fluxes follow a linear profile with height. This assumption is carefully tested and the deviation from linearity is quantified. The budget calculation allows us to assess the importance of advection of heat and CO2 during day hours for three selected days. It is found that, under nonadvective conditions, the diurnal variability of temperature and CO2 is well reproduced from the flux divergence measurements. Consequently, the vertical transport due to the turbulent flux plays a major role in the daytime evolution of both scalars and the advection is a relatively small contribution. During the analyzed days with a strong contribution of advection of either heat or carbon dioxide, the flux divergence is still an important contribution to the budget. For heat, the quantification of the advection contribution is in close agreement with results from a numerical model. For carbon dioxide, we qualitatively corroborate the results with a Lagrangian transport model. Our estimation of advection is compared with traditional estimations based on the Net Ecosystem-atmosphere Exchange (NEE)
