    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. In this cohort, we found no evidence of impaired postural balance. Head repositioning accuracy and computerized static posturography are imperfect measures of functional proprioceptive impairments. Validity of (and procedures for using these

    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 affect the proprioception function of the neck. Supporting the upper extremities in such a way that their weight is unloaded, which leads to reduction in the tension between the neck and shoulder girdle, can improve cervicocephalic kinesthetic 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.

    About 20 cases of cerebrovascular accidents in amusement parks have been documented. However, only a few cases of amusement park stroke (APS) after roller coaster rides have been reported. Here, we present triggers of stroke, clinical characteristics, and the angiographic appearance of 3 consecutive patients of APS. Their clinical characteristics included young age, absence of atherosclerotic risk factors, and severe injuries. Serial changes in angiographic appearance led to the diagnosis of cervicocephalic artery dissection (CAD). Patients A and B were diagnosed with isolated middle cerebral artery (MCA) dissection, and patient C was diagnosed with internal carotid artery dissection involving MCA dissection. Running excitedly toward an attraction in patient A, a go-kart ride in patient B, and riding in an enhanced motion vehicle in patient C were considered as the likely triggers for APS. We had specific cases with APS associated with CAD, which can occur under diverse contexts other than roller coaster rides at amusement parks. Our findings suggest that the variable directions of the high gravitational forces induced by vehicle riding or running excitedly might injure the MCA or internal carotid artery, and thereby cause CAD in the amusement park.

    The perception theory of Affolter (1987), the theory of sensory integration of Ayres (1979, 1984) as well as the development theory of Piaget (1973) consider sensorimotor experiences as a basis for the child's cognitive development. Tactile-kinesthetic perception has hereby a central position. In the German-speaking psychology, no standardized tests exist to measure the developmental age of tactile-kinesthetic perception in early childhood. The subtests of neuropsychological batteries have not been primarily constructed for young children, therefore they may not portray the age dependence of tactile-kinesthetic perception exactly. That is why we have collected a pool of items, empirically based descriptors of tactile-kinesthetic behavior, to test this perceptual modality. Then we proved it in a series of pretests. The resulting preliminary developmental test contains 7 functions: Localization of touch, pressure sensibility, two-point-discrimination, finger identification, object stereognosis, stereognosis of object properties, and graphesthesia. It was administered to 111 children aged from 3;2 to 6;5 years in kindergarten. Data of the item analysis demonstrated that many items proved to be to easy. Nevertheless, the instrument is useful and measures reliably. The deficits of the experimental test version will now be corrected by a revision. We will start a detailed analysis again using the revised test.

    Full Text Available Kinesthesia is our sense of limb motion, and allows us to gauge the speed, direction, and amplitude of our movements. Over half of stroke survivors have significant impairments in kinesthesia, which leads to greatly reduced recovery and function in everyday activities. Despite the high reported incidence of kinesthetic deficits after stroke, very little is known about how damage beyond just primary somatosensory areas affects kinesthesia. Stroke provides an ideal model to examine structure-function relationships specific to kinesthetic processing, by comparing lesion location with behavioral impairment. To examine this relationship, we performed voxel-based lesion-symptom mapping and statistical region of interest analyses on a large sample of sub-acute stroke subjects (N=142 and compared kinesthetic performance with stroke lesion location. Subjects with first unilateral, ischemic stroke underwent neuroimaging and a comprehensive robotic kinesthetic assessment (~9 days post-stroke. The robotic exoskeleton measured subjects’ ability to perform a kinesthetic mirror-matching task of the upper limbs without vision. The robot moved the stroke-affected arm and subjects’ mirror-matched the movement with the unaffected arm. We found that lesions both within and outside primary somatosensory cortex were associated with significant kinesthetic impairments. Further, sub-components of kinesthesia were associated with different lesion locations. Impairments in speed perception were primarily associated with lesions to the right post-central and supramarginal gyri whereas impairments in amplitude of movement perception were primarily associated with lesions in the right pre-central gyrus, anterior insula, and superior temporal gyrus. Impairments in perception of movement direction were associated with lesions to bilateral post-central and supramarginal gyri, right superior temporal gyrus and parietal operculum. All measures of impairment shared a common

    Saccades to somatosensory targets have longer latencies and are less accurate and precise than saccades to visual targets. Here we examined how different somatosensory information influences the planning and control of saccadic eye movements. Participants fixated a central cross and initiated a saccade as fast as possible in response to a tactile stimulus that was presented to either the index or the middle fingertip of their unseen left hand. In a static condition, the hand remained at a target location for the entire block of trials and the stimulus was presented at a fixed time after an auditory tone. Therefore, the target location was derived only from proprioceptive and tactile information. In a moving condition, the hand was first actively moved to the same target location and the stimulus was then presented immediately. Thus, in the moving condition additional kinesthetic information about the target location was available. We found shorter saccade latencies in the moving compared to the static condition, but no differences in accuracy or precision of saccadic endpoints. In a second experiment, we introduced variable delays after the auditory tone (static condition) or after the end of the hand movement (moving condition) in order to reduce the predictability of the moment of the stimulation and to allow more time to process the kinesthetic information. Again, we found shorter latencies in the moving compared to the static condition but no improvement in saccade accuracy or precision. In a third experiment, we showed that the shorter saccade latencies in the moving condition cannot be explained by the temporal proximity between the relevant event (auditory tone or end of hand movement) and the moment of the stimulation. Our findings suggest that kinesthetic information facilitates planning, but not control, of saccadic eye movements to proprioceptive-tactile targets.

    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.

  1. 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. 

  2. Kinesthetic activities in physics instruction: Image schematic justification and design based on didactic situations

    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...

    Motor imagery can be divided into kinesthetic and visual aspects. In the present study, we investigated excitability in the corticospinal tract and primary visual cortex (V1) during kinesthetic and visual motor imagery. To accomplish this, we measured motor evoked potentials (MEPs) and probability of phosphene occurrence during the two types of motor imageries of finger tapping. The MEPs and phosphenes were induced by transcranial magnetic stimulation to the primary motor cortex and V1, respectively. The amplitudes of MEPs and probability of phosphene occurrence during motor imagery were normalized based on the values obtained at rest. Corticospinal excitability increased during both kinesthetic and visual motor imagery, while excitability in V1 was increased only during visual motor imagery. These results imply that modulation of cortical excitability during kinesthetic and visual motor imagery is task dependent. The present finding aids in the understanding of the neural mechanisms underlying motor imagery and provides useful information for the use of motor imagery in rehabilitation or motor imagery training.

    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.

    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.

    2014-06-01

    This article reports the outcomes of a kinesthetic learning strategy used during a cardiac lecture to engage students and to improve the use of classroom-acquired knowledge in today's challenging clinical settings. Nurse educators are constantly faced with finding new ways to engage students, stimulate critical thinking, and improve clinical application in a rapidly changing and complex health care system. Educators who deviate from the traditional pedagogy of didactic, content-driven teaching to a concept-based, student-centered approach using active and kinesthetic learning activities can enhance engagement and improve clinical problem solving, communication skills, and critical thinking to provide graduates with the tools necessary to be successful. The goals of this learning activity were to decrease the well-known classroom-clinical gap by enhancing engagement, providing deeper understanding of cardiac function and disorders, enhancing critical thinking, and improving clinical application.

    2009-01-01

    Amebiasis caused by Entamoeba histolytica is a problem of public world health. The most frequent clinical presentation are the dysentery and the amebic liver abscess. Fifty millions of cases and more than 100.000 deaths for this disease are reported annually worldwide. The life cycle of E. 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 104 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.

    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.

    Needle insertion in soft-tissue is a minimally invasive surgical procedure that demands high accuracy. In this respect, robotic systems with autonomous control algorithms have been exploited as the main tool to achieve high accuracy and reliability. However, for reasons of safety and responsibility, autonomous robotic control is often not desirable. Therefore, it is necessary to focus also on techniques enabling clinicians to directly control the motion of the surgical tools. In this work, we address that challenge and present a novel teleoperated robotic system able to steer flexible needles. The proposed system tracks the position of the needle using an ultrasound imaging system and computes needle's ideal position and orientation to reach a given target. The master haptic interface then provides the clinician with mixed kinesthetic-vibratory navigation cues to guide the needle toward the computed ideal position and orientation. Twenty participants carried out an experiment of teleoperated needle insertion into a soft-tissue phantom, considering four different experimental conditions. Participants were provided with either mixed kinesthetic-vibratory feedback or mixed kinesthetic-visual feedback. Moreover, we considered two different ways of computing ideal position and orientation of the needle: with or without set-points. Vibratory feedback was found more effective than visual feedback in conveying navigation cues, with a mean targeting error of 0.72 mm when using set-points, and of 1.10 mm without set-points.

    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.

    Various approaches in learning are commonly classified into visual, auditory and kinesthetic (VAK) learning styles. One way of addressing the VAK learning styles is through game-based learning which motivates learners pursue knowledge holistically. The paper presents Kinespell, an unconventional method of learning through digital game-based learning. Kinespell is geared towards enhancing not only the learner’s spelling abilities but also the motor skills through utilizing wireless controllers. It monitors player’s performance through integrated assessment scheme. Results show that Kinespell may accommodate the VAK learning styles and is a promising alternative to established methods in learning and assessing students’ performance in Spelling.

    The meridional eddy flux of sensible heat is examined by means of finite difference integration methods from northern hemisphere charts for the winter 1945-46. The eddy sensible heat flux is shown to occur principally in the lowest layers of the atmosphere and to decrease with elevation. The magnitude of the eddy sensible heat transports are compared with the total poleward energy flux required by the radiation balance, and are shown to comprise a very large fraction of this flux.DOI: 10.1111...

    Piezoelectric motors offer an attractive alternative to electromagnetic actuators in portable haptic interfaces: they are compact, have a high force-to-volume ratio, and can operate with limited or no gearing. However, the choice of a piezoelectric motor type is not obvious due to differences in performance characteristics. We present our evaluation of two commercial, operationally different, piezoelectric motors acting as actuators in two kinesthetic haptic grippers, a walking quasi-static motor and a traveling wave ultrasonic motor. We evaluate each gripper's ability to display common virtual objects including springs, dampers, and rigid walls, and conclude that the walking quasi-static motor is superior at low velocities. However, for applications where high velocity is required, traveling wave ultrasonic motors are a better option.

    Recent research on manual tracking with a kinesthetic-tactual (KT) display suggests that under certain conditions it can be an effective alternative or supplement to visual displays. In order to understand better how KT tracking compares with visual tracking, both a critical tracking and stationary single-axis tracking tasks were conducted with and without velocity quickening. In the critical tracking task, the visual displays were superior, however, the quickened KT display was approximately equal to the unquickened visual display. In stationary tracking tasks, subjects adopted lag equalization with the quickened KT and visual displays, and mean-squared error scores were approximately equal. With the unquickened displays, subjects adopted lag-lead equalization, and the visual displays were superior. This superiority was partly due to the servomotor lag in the implementation of the KT display and partly due to modality differences.

    Recent research on manual tracking with a kinesthetic-tactual (KT) display suggests that under appropriate conditions it may be an effective means of providing visual workload relief. In order to better understand how KT tracking differs from visual tracking, both a critical tracking task and stationary single-axis tracking tasks were conducted with and without velocity quickening. On the critical tracking task, the visual displays were superior; however, the KT quickened display was approximately equal to the visual unquickened display. Mean squared error scores in the stationary tracking tasks for the visual and KT displays were approximately equal in the quickened conditions, and the describing functions were very similar. In the unquickened conditions, the visual display was superior. Subjects using the unquickened KT display exhibited a low frequency lead-lag that may be related to sensory adaptation.

    BACKGROUND: Letter-by-letter readers identify each letter of the word they are reading serially in left to right order before recognizing the word. When their letter naming is also impaired, letter-by-letter reading is inaccurate and can render even single word reading very poor. Tactile and/or kinesthetic strategies have been reported to improve reading in these patients, but only under certain conditions or for a limited set of stimuli. AIMS: The primary aim of the current study was to determine whether a tactile/kinesthetic treatment could significantly improve reading specifically under normal reading conditions, i.e. reading untrained words presented in free vision and read without overt use of the strategy. METHODS #ENTITYSTARTX00026; PROCEDURES: Three chronic letter-by-letter readers participated in a tactile/kinesthetic treatment aimed at first improving letter naming accuracy (phase 1) and then letter-by-letter reading speed (phase 2). In a multiple case series design, accuracy and speed of reading untrained words without overt use of the trained tactile/kinesthetic strategy was assessed before phase 1, after phase 1 and again after phase 2. OUTCOMES #ENTITYSTARTX00026; RESULTS: All three patients significantly improved both their speed and accuracy reading untrained words without overt use of the trained tactile/kinesthetic strategy. All three patients required the additional practice in phase 2 to achieve significant improvement. Treatment did not target sentence level reading, yet two of the three patients became so adept that they could read entire sentences. CONCLUSIONS: This study replicates previous findings on the efficacy of tactile/kinesthetic treatment for letter-by-letter readers with poor letter naming. It further demonstrates that this treatment can alter cognitive processing such that words never specifically trained can be read in free vision without overtly using the trained strategy. The data suggest that an important element in achieving

    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.

    Thermal energy storage is a technology under investigation since the early 1970s. Since then, numerous new applications have been found and much work has been done to bring this technology to the market. Nevertheless, the materials used either for latent or for sensible storage were mostly investigated 30 years ago, and the research has lead to improvement in their performance under different conditions of applications. In those years a significant number of new materials were developed in many fields other than storage and energy, but a great effort to characterize and classify these materials was done. Taking into account the fact that thousands of materials are known and a large number of new materials are developed every year, the authors use the methodology for materials selection developed by Prof. Ashby to give an overview of other materials suitable to be used in thermal energy storage. Sensible heat storage at temperatures between 150 and 200 C is defined as a case study and two different scenarios were considered: long term sensible heat storage and short term sensible heat storage.

    Although kinesthesia is known to largely depend on afferent inflow, recent data suggest that central signals originating from volitional control (efferent outflow) could also be involved and interact with the former to build up a coherent percept. Evidence derives from both clinical and experimental observations where vision, which is of primary importance in kinesthesia, was systematically precluded. The purpose of the present experiment was to assess the role of volitional effort in kinesthesia when visual information is available. Participants (n=20) produced isometric contraction (10-20% of maximal voluntary force) of their right arm while their left arm, which image was reflected in a mirror, either was passively moved into flexion/extension by a motorized manipulandum, or remained static. The contraction of the right arm was either congruent with or opposite to the passive displacements of the left arm. Results revealed that in most trials, kinesthetic illusions were visually driven, and their occurrence and intensity were modulated by whether volitional effort was congruent or not with visual signals. These results confirm the impact of volitional effort in kinesthesia and demonstrate for the first time that these signals interact with visual afferents to offer a coherent and unified percept.

    In this paper, the analysis and design of master-slave teleoperation systems are discussed. The goal of this paper is to build a superior master-slave system that can provide good maneuverability. The authors first analyze a one degree-of-freedom system including operator and object dynamics. Second, some ideal responses of master-slave systems are defined and a quantitative index of maneuverability is given, based on the concept of ideal responses. Third, the authors proposed new control schemes of master-slave manipulators that provide the ideal kinesthetic coupling such that the operator can maneuver the system as through he/she were directly manipulating the remote object himself/herself. The proposed control scheme requires accurate dynamic models of the master and slave arms, but neither parameters of the remote object nor the operator dynamics is necessary. Last, the proposed control scheme is introduced to a prototype master-slave system and the experimental results show the validity of the proposed scheme.

    In two experiments using a center-out task, we investigated kinesthetic-motor and auditory-motor integrations in 5- to 12-year-old children and young adults. In experiment 1, participants moved a pen on a digitizing tablet from a starting position to one of three targets (visuo-motor condition), and then to one of four targets without visual feedback of the movement. In both conditions, we found that with increasing age, the children moved faster and straighter, and became less variable in their feedforward control. Higher control demands for movements toward the contralateral side were reflected in longer movement times and decreased spatial accuracy across all age groups. When feedforward control relies predominantly on kinesthesia, 7- to 10-year-old children were more variable, indicating difficulties in switching between feedforward and feedback control efficiently during that age. An inverse age progression was found for directional endpoint error; larger errors increasing with age likely reflect stronger functional lateralization for the dominant hand. In experiment 2, the same visuo-motor condition was followed by an auditory-motor condition in which participants had to move to acoustic targets (either white band or one-third octave noise). Since in the latter directional cues come exclusively from transcallosally mediated interaural time differences, we hypothesized that auditory-motor representations would show age effects. The results did not show a clear age effect, suggesting that corpus callosum functionality is sufficient in children to allow them to form accurate auditory-motor maps already at a young age.

    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.

    Full Text Available Background and Objectives: Every individual has different learning style. As dental educators, it is necessary to recognize the fact that each dental student may have a preference of acquiring information and skill in one style over another. The objective of this study was to determine the learning style preferences of dental students using the Visual, Aural, Read-Write, Kinesthetic (VARK questionnaire. Materials and Methods: The VARK questionnaire was administered to 20 1 st year and 40 2 nd year dental students of Melaka Manipal Medical College, Manipal University to determine their preferred mode of learning. Completed questionnaires were scored and tabulated to determine the distribution of VARK preferences. Results: Nearly 50% of 1 st year students were quadmodal whereas 55% of 2 nd year students were unimodal in which kinesthetic preference was dominant. Mean V and A scores were significantly higher for 1 st year than 2 nd year students. No significant gender difference was seen. Conclusion: The dental students in this study had varied learning preferences. As dental educators, we need to adopt different methods of teaching in order to reach most of the students and make the educational experience more productive.

    2016-08-01

    The paper explores a process of growth represented in the interplay of Jane Austen's characterizations of Marianne and Elinor Dashwood in Sense and Sensibility, approaching the text through the lens of psychoanalytic theories on oedipal sibling rivalry, separation, and processes of change. A close reading of Sense and Sensibility tracks Marianne Dashwood's repudiation of any 'second attachment' as the surface of an unconscious fantasy, denying a rival for the mother's love. A psychoanalytic view contrasts Marianne's lack of separation from her mother, her use of denial and projection, and her near death after losing the man she loves, with her older sister Elinor Dashwood's capacities for depression, reflection, and greater acceptance of loss and separation. The narrative portrays Mrs. Dashwood's identification with and idealization of her daughter Marianne, which contribute to her oedipal sibling 'victory'. In the language and structure of the novel, the projections, identifications, aggressions, and separations (conscious and unconscious) of the sisters in the vicissitudes of their adolescent loves and rivalries constitute a process of growth. Austen's novel brings to life, with the vividness and coherence of great literature, forces and fantasies in oedipal sibling rivalries, inspiring renewed attention to their subtle presence in the transference and countertransference of the psychoanalytic process.

  6. Subjectivity and vulnerability: reflections on the foundation of ethical sensibility.

    2003-10-01

    This paper investigates the possibility of understanding the rudimentary elements of clinical sensitivity by investigating the works of Edmund Husserl and Emmanuel Levinas on sensibility. Husserl's theory of intentionality offers significant reflections on the role of pre-reflective and affective intuition as a condition for intentionality and reflective consciousness. These early works of Husserl, in particular his works on the constitution of phenomenological time and subjective time-consciousness, prove to be an important basis for Levinas' works on an ethics of alterity and infinite responsibility for the other person. In fact, it is difficult to understand the core of Levinasian ethics, of vulnerability as proximity, of ethical sensitivity as passivity and a suffering for the suffering of another, without understanding the influence from Husserl's work. Crucially, the paper will, on the basis of Levinasian ethics, establish an understanding of sensibility as vulnerability and receptivity that is fundamental also for understanding significant intuitions in clinical nursing. Clinical sensitivity and carefulness in nursing are shaped by the concrete and also bodily expressions of vulnerabilities in a receptivity that is pre-reflective and pre-ontological.

    The CHUVA project (Cloud processes of tHe main precipitation systems in Brazil: A contribUtion to cloud resolVing modeling and to the GPM (GlobAl Precipitation Measurement)) is a Brazillian experiment that aims to understand the several cloud processes that occur in different precipitating regimes. At present, the CHUVA project has conducted 6 field campaigns, the last one being in Manaus jointly with GoAmazon, IARA and ACRIDICON. The main focus of the present study is to bring into perspective the different characteristics of precipitation that reaches the surface in Brazil over several locations. To do so, disdrometer data is analyzed in detail, employing a Gamma fit for each DSD measurement which provides the respective parameters to be studied. Those are disposed in a 3D space, each axis corresponding to one parameter, and the patterns are analyzed. A correlation between the Gamma parameters is defined as a parametric surface that fits the observations with errors smaller than 10% and R2 greater than 0.95. In this way, one parameter can be estimated with respect to the other two, reducing the degrees of freedom of the problem from 3 to 2. As the 3 parameters are defined over this surface, it's possible to obtain a surface representing integral DSD properties such as rainfall intensity (RI). Sensibilities tests are conducted on this estimation and also on other DSD characteristics such as total droplet concentrations and mean mass-weighted diameter. It's shown that the DSD integral properties are generally very sensitive to the Gamma parameters. Nonetheless, the sensibility varies over the surface, being higher in a region where the parameters are not balanced (i.e. a relatively high value in one parameter and low values on the other two). It's suggested that any study proposing parameterization/estimation of DSD properties should be aware of this region of high sensitivity. To further the collaboration with GoAmazon and ACRIDICON, the disdrometer results

    1990-12-01

    Results of an on-going program to develop a composite latent-sensible thermal energy storage medium, trade marked CompPhase, are presented. The target application area was periodic kiln energy recovery. The concept is that of a composite salt/ceramic material processed such that the medium maintains its shape and mechanical integrity through the salt melting temperature. As such, the media can be fabricated into a variety of shapes suitable for packed beds, fluidized beds, or direct contact heat exchangers. The properties of ten carbonate salt or eutectic mixtures of carbonate salts were reviewed to select the most appropriate candidates for development. Three salts and two ceramic materials were evaluated in laboratory tests to select the final material, a composite of sodium-barium eutectic/magnesium oxide, for development. Two methods of processing the constituent powders for fabrication into storage pellets were developed, and one method was applied to pellet fabrication by commercial processing equipment. Two different preliminary cost estimates bracketed the expected cost of commercially fabricating storage pellets. Also, two modifications to the material processing method were suggested to reduce costs. Thermal cycling was conducted on laboratory produced experimental pellets and on prototype pellets fabricated by commercial processes. Detailed laboratory tests to determine composite mechanical and thermal properties were conducted. It is concluded that further laboratory, field, and economic studies are required before the concept of composite storage media can be considered fully developed for commercialization.

  13. Sensible energy policy does not include a variable import fee

    Lave, L.B. (Carnegie-Mellon Univ., Schenley Park, Pittsburgh, PA (US))

    1988-01-01

    Energy analysis has become unfashionable. The millions of dollars and professional hours devoted to fashioning solutions to the US energy problems in the late 1970s have disappeared with little trce. With world oil selling below $20 per barrel, there is little or no interest in alternatives to petroleum, or even in R and D on alternatives. Current apathy suggests that the USA is capable of only two modes of operation: Throw money at perceived crises, knowing it is being spent foolishly, or ignore any problem that ceases to be a perceived crises. Energy policy seems to be thought of these days as bailing out the oil billionaires and the Texas banks and savings and loan situations. When mature, consenting adults spend years trying to bring something about, one should allow them to enjoy the fruits of their labor - as long as it is within the law. Thus, the author assumes that Singer's proposal is not to be justified on the grounds of pulling these chestnuts out of the fire. Rather, Singer puts it forth on the grounds that it will contribute to sensible energy policy. Unfortunately, the variable import fee (VIF) is seriously flawed and the supporting arguments are contradictory or unsupported. In order to evaluate a proposal such as Singer's VIF, one has to be clear on the objectives and time frame. Others and the author agree that at any date, there is a supply curve for domestic petroleum that rises with price. There are stripping well secondary and tertiary recovery all waiting, and drillers willing to bring in new wells; the higher the price, the more oil will flow from these sources.

    Searson, Robert Francis

    This researcher investigated the effects of tactual and kinesthetic instructional resources on the simple recall and higher-level cognitive science achievement and attitudes toward science of third-grade suburban students in a northern New Jersey school district. The Learning Style Inventory (LSI) (Dunn, Dunn, & Price, 1996) was administered to ascertain the identity of the learning-style perceptual preferences of all 59 third-graders who completed the three science units. Each of the three classes was presented two science units using learning-style instructional resources; one science unit was taught using traditional methods. All three science units were completed in a six-week period. Students were administered a pretest and posttest for each science unit and the Semantic Differential Scale (Pizzo, 1981) at the conclusion of each science unit. Analysis of variance (ANOVA) assessed the effects of treatments and attitudes toward science. The statistical analysis of this study revealed a significant difference (p traditionally. Furthermore, the Contingency Table analysis, using Fisher's Exact Test indicated a significant difference (p = 0.00008) between the higher-level cognitive science achievement posttest scores when students are taught science tactually and/or kinesthetically compared to when they are taught science traditionally. The findings of this study supported the view when tactual and/or kinesthetic methods were employed, higher achievement gains were realized for simple recall and higher-level cognitive science achievement. Further recommendations called for a reexamination of science instructional methods employed in our elementary classroom.

  15. 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.

    Kinesthetic illusions by visual stimulation (KiNVIS) enhances corticomotor excitability and activates motor association areas. The purpose of this study was to investigate the effect of KiNVIS induction on muscular output function after short-term immobilization. Thirty subjects were assigned to 3 groups: an immobilization group, with the left hand immobilized for 12h (immobilization period); an illusion group, with the left hand immobilized and additionally subjected to KiNVIS of the immobilized part during the immobilization period; and a control group with no manipulation. The maximum voluntary contraction (MVC), fluctuation of force (force fluctuation) during a force modulation task, and twitch force were measured both before (pre-test) and after (post-test) the immobilization period. Data were analyzed by performing two-way (TIME×GROUP) repeated measures ANOVA. The MVC decreased in the immobilization group only (pre-test; 37.8±6.1N, post-test; 32.8±6.9N, p<0.0005) after the immobilization period. The force fluctuation increased only in the immobilization group (pre-test; 2.19±0.54%, post-test; 2.78±0.87%, p=0.007) after the immobilization period. These results demonstrate that induction of KiNVIS prevents negative effect on MVC and force fluctuation after 12h of immobilization.

  17. How Kinesthetic Motor Imagery works: a predictive-processing theory of visualization in sports and motor expertise.

    2015-01-01

    Kinesthetic Motor Imagery (KMI) is an important technique to acquire and refine motor skills. KMI is widely used by professional athletes as an effective way to improve motor performance without overt motor output. Despite this obvious relevance, the functional mechanisms and neural circuits involved in KMI in sports are still poorly understood. In the present article, which aims at bridging the sport sciences and cognitive neurophysiology literatures, we give a brief overview of relevant research in the field of KMI. Furthermore, we develop a theoretical account that relates KMI to predictive motor control theories assuming that it is based on internal activation of anticipatory images of action effects. This mechanism allows improving motor performance solely based on internal emulation of action. In accordance with previous literature, we propose that this emulation mechanism is implemented in brain regions that partially overlap with brain areas involved in overt motor performance including the posterior parietal cortex, the cerebellum, the basal ganglia and the premotor cortex. Finally, we outline one way to test the heuristic value of our theoretical framework for KMI; we suggest that experience with motor performance improves the ability to correctly infer the goals of others, in particular in penalty blocking in soccer.

  18. Data’s Intimacy: Machinic Sensibility and the Quantified Self

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Today, machines observe, record the world – not just for us, but sometimes instead of us (in our stead, and even indifferently to us humans. And yet, remain human. Correlationism may not be up to a comprehensive ontology, but the ways in which we encounter, and struggle to make some kind of sense of, machinic sensibility matters. The nature of that encounter is not instrumentality, or even McLuhanian extension, but a full-blown ‘relationship’ where the terms by which machines ‘experience’ the world, and communicate with each other, parametrises the conditions for our own experience. This essay will play out one such relationship currently in the making: the boom in self-tracking technologies, and the attendant promise of data’s intimacy. This essay proceeds in three sections, all of which draw on a larger research project into self-tracking and contemporary data epistemologies. It thus leverages observations from close reading of self-tracking’s publicisation in the mass media between 2007 and 2016; analysis of over fifty self-tracking products, some of it through self-experimentation; and interviews and ethnographic observation, primarily of the ‘Quantified Self’ connoisseur community. The first section examines the dominant public presentations of self-tracking in early twenty-first century discourse. This discourse embraces a vision of automated and intimate self-surveillance, which is then promised to deliver superior control and objective knowledge over the self. Next, I link these promises to the recent theoretical turns towards the agency of objects and the autonomous sensory capacities of new media to consider the implications of such theories – and the technological shifts they address – for the phenomenology of the new media subject. Finally, I return to self-tracking discourse to consider its own idealisation of such a subject – what I call ‘data-sense’. I conclude by calling for a more explicit public and

    Based on measurements at Sodankyla Meteorological Observatory the regional (aggregated) momentum and sensible heat fluxes are estimated for two days over a site in Finnish Lapland during late winter. The forest covers 49% of the area. The study shows that the forest dominates and controls...... the regional fluxes of momentum and sensible heat in different ways. The regional momentum flux is found to be 10-20% smaller than the measured momentum flux over the forest, and the regional sensible heat flux is estimated to be 30-50% of the values measured over a coniferous forest. The regional momentum...... flux is determined in two ways, both based on blending height theory. One is a parameterised method, the other represents a numerical solution of an aggregation model. The regional sensible heat flux is determined from the theory of mixed-layer growth. At near neutral conditions the regional momentum...

    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.

  4. THE STUDY ON LATENT AND SENSIBLE HEAT FLUX OVER MIRE IN THE SANJIANG PLAIN

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Understanding how surface energy fluxes respond to environmental variables and how their components vary on daily and seasonal temporal scales are critical for understanding the ecological process of wetland ecosystem. In view of the fact that studies on surface energy flux over mire in China have been very limited, we have initiated a long-term latent and sensible heat flux (two main components of the surface energy balance) observation over mire in the Sanjiang Plain from June to October in 2004 with the eddy covariance technique. Results showed that the latent and sensible heat flux had large seasonal and diurnal variation during the period of measurement. Generally, latent heat flux between the mire wetland and the atmosphere reached the maximum value in June and then gradually decreased from June to October, whose daily mean fluxes were 9.83,8.00,7.33, 4.82 and 2.04 MJ/(m2·d), respectively. By comparison, sensible heat flux changed unnoticeably with season change from June to October, which were 1.47,0.88,1.75, 1.61,1.33 MJ/(m2·d) respectively. The diurnal variation of both latent and sensible heat flux varied noticeably within a day. After the sunrise, the latent and sensible heat flux increased and reached the maximum at noon (11:00-13:00). Then they decreased gradually and reached the minimum value during the nighttime. The patterns of temporal variation in latent and sensible heat flux were significantly controlled by environmental factors. The latent heat flux was linearly dependent on net radiation and increased with increasing vapour pressure deficit until the vapour pressure deficit surpassed 11 hPa. Wind speed effect on latent heat flux was more complicated and, in general, showed a positive correlation between them in daytime. The sensible heat flux was controlled mainly by air temperature difference between the land surface and the overlying air. However, when the temperature difference was larger than 0.3 ℃, it had no effect on the sensible

    This paper studied the diurnal and seasonal characteristics of sensible and latent heat fluxes over a temperate desert steppe ecosystem in Inner Mongolia, based on the 2008 observation data from eddy covariance tower. The diurnal patterns of sensible and latent heat fluxes over the ecosystem were both single kurtosis, with the maximum value being 319.01 W x m(-2) (on May 30th, 2008) and 425.37 W x m(-2) (on Jun 2nd, 2008), respectively, and occurred at about 12:00-13:30 (local time), which was similar to the diurnal pattern of net radiation but lagged about one hour of the maximum net radiation. The maximum diurnal variations of monthly mean sensible and latent heat fluxes occurred in May and June, and their minimum diurnal variations occurred in January and November, respectively. There was a closer relationship between soil moisture content and precipitation. Surface soil moisture content was most sensitive to precipitation, while the moisture content in deeper soil layers had a lagged response to precipitation. The seasonal dynamics of sensible and latent heat fluxes was similar to that of net radiation, and affected by precipitation. Sensible heat flux was obviously affected by net radiation, but latent heat flux was more sensitive to precipitation and mainly controlled by soil moisture content.

  6. "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.

    Separate Sensible and Latent cooling (SSLC) has been discussed in open literature as means to improve air conditioning system efficiency. The main benefit of SSLC is that it enables heat source optimization for the different forms of loads, sensible vs. latent, and as such maximizes the cycle efficiency. In this paper I use a thermodynamic analysis tool in order to analyse the performance of various SSLC technologies including: multi-evaporators two stage compression system, vapour compression system with heat activated desiccant dehumidification, and integrated vapour compression with desiccant dehumidification. A primary coefficient of performance is defined and used to judge the performance of the different SSLC technologies at the design conditions. Results showed the trade-off in performance for different sensible heat factor and regeneration temperatures.

  9. 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.

    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.

    Full Text Available Evapotranspiration rates at the catchment scale are very difficult to quantify. One possible manner to continuously observe this variable could be the estimation of sensible heat fluxes (H across large distances (in the order of kilometers using a large aperture scintillometer (LAS, and inverting these observations into evapotranspiration rates, under the assumption that the LAS observations are representative for the entire catchment. The objective of this paper is to assess whether measured sensible heat fluxes from a LAS over a long distance (9.5 km can be assumed to be valid for a 102.3 km2 heterogeneous catchment. Therefore, a fully process-based water and energy balance model with a spatial resolution of 50 m has been thoroughly calibrated and validated for the Bellebeek catchmentin Belgium. A footprint analysis has been performed. In general, the sensible heat fluxes from the LAS compared well with the modeled sensible heat fluxes within the footprint. Moreover, as the modeled Hwithin the footprint has been found to be almost equal to the modeled catchment averaged H, it can be concluded that the scintillometer measurements over a distance of 9.5 km and an effective heightof 68 m are representative for the entire catchment.

    Introduction: The purpose of this study was to assess the accuracy of sensibility tests by correlating it with histologic pulp condition. Methods and Materials: Assessment of clinical signs and symptoms were performed on 65 permanent teeth that were scheduled to be extracted for periodontal, prosthodontic or orthodontic reasons. The normal pulp and reversible pulpitis were considered as treatable tooth conditions while irreversible pulpitis and necrosis were considered as untreatable conditions. The teeth were then extracted and sectioned for histological analysis of dental pulp. Histologic status and classification corresponded to the treatable or untreatable pulp condition. Comparisons between histological treatable and untreatable pulp condition were performed with chi-square analysis for sensibility test responses. The positive predictive value (PPV), negative predictive value (NPV) and accuracy to detect untreatable from treatable pulp condition were calculated for each test. Results: A significant difference was detected in the normal and a sharp lingered response to heat and cold tests. There was significant difference in the negative response to EPT between histological groups. The kappa agreement coefficient between clinical and histological diagnosis of pulp condition was about 0.843 (P<0.001). The accuracy of cold and heat tests and EPT to detect treatable pulp or untreatable pulp states were 78, 74 and 62%, respectively. The sensibility tests diagnosed untreatable pulpitis with a higher probability (NPV=63%-67% -54%, PPV=83%-91% -95% for heat, cold and EPT, respectively). Conclusion: Sensibility test results were more likely to diagnose pulpal disease or untreatable pulp conditions. However, to increase the diagnostic accuracy patient history, clinical signs and symptoms and also radiographic findings in conjunction with sensibility tests must be used. The result of this small study demonstrated a good agreement between clinical and histological pulp

    It is generally believed that the human right cerebral hemisphere plays a dominant role in corporeal awareness, which is highly associated with conscious experience of the physical self. Prompted by our previous findings, we examined whether the right frontoparietal activations often observed when people experience kinesthetic illusory limb movement are supported by a large-scale brain network connected by a specific branch of the superior longitudinal fasciculus fiber tracts (SLF I, II, and III). We scanned brain activity with functional magnetic resonance imaging (MRI) while nineteen blindfolded healthy volunteers experienced illusory movement of the right stationary hand elicited by tendon vibration, which was replicated after the scanning. We also scanned brain activity when they executed and imagined right hand movement, and identified the active brain regions during illusion, execution, and imagery in relation to the SLF fiber tracts. We found that illusion predominantly activated the right inferior frontoparietal regions connected by SLF III, which were not substantially recruited during execution and imagery. Among these regions, activities in the right inferior parietal cortices and inferior frontal cortices showed right-side dominance and correlated well with the amount of illusion (kinesthetic illusory awareness) experienced by the participants. The results illustrated the predominant involvement of the right inferior frontoparietal network connected by SLF III when people recognize postural changes of their limb. We assume that the network bears a series of functions, specifically, monitoring the current status of the musculoskeletal system, and building-up and updating our postural model (body schema), which could be a basis for the conscious experience of the physical self.

    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.

    Possible linkages between Arctic sea ice loss and midlatitude weather are strongly debated in the literature. We analyze a coupled model simulation to assess the possibility of Arctic ice variability forcing a midlatitude response, ensuring consistency between atmosphere, ocean, and ice components. We work with weekly running mean daily sensible heat fluxes with the self-organizing map technique to identify Arctic sensible heat flux anomaly patterns and the associated atmospheric response, without the need of metrics to define the Arctic forcing or measure the midlatitude response. We find that low-level warm anomalies during autumn can build planetary wave patterns that propagate downstream into the midlatitudes, creating robust surface cold anomalies in the eastern United States.

    Micro-meteorological tower observations of MONTBLEX (Monsoon Trough Boundary Layer Experiment)-1990, combined with routine surface observations at Jodhpur in the dry convective sector of Indian summer monsoon trough are used to examine the interrelationship between total cloud cover (TCC) and surface sensible heat flux (SHF) during the summer monsoon of 1990. A significant inverse relationship between TCC and SHF is found during various Intensive Observation Periods of the experiment. This relationship holds for the various methods of estimation of SHF.

    Full Text Available The CarboEurope Regional Experiment Strategy (CERES was designed to develop and test a range of methodologies to assess regional surface energy and mass exchange of a large study area in the south-western part of France. This paper describes a methodology to estimate sensible and latent heat fluxes on the basis of net radiation, surface radiometric temperature measurements and information obtained from available products derived from the Meteosat Second Generation (MSG geostationary meteorological satellite, weather stations and ground-based eddy covariance towers. It is based on a simplified bulk formulation of sensible heat flux that considers the degree of coupling between the vegetation and the atmosphere and estimates latent heat as the residual term of net radiation. Estimates of regional energy fluxes obtained in this way are validated at the regional scale by means of a comparison with direct flux measurements made by airborne eddy-covariance. The results show an overall good matching between airborne fluxes and estimates of sensible and latent heat flux obtained from radiometric surface temperatures that holds for different weather conditions and different land use types. The overall applicability of the proposed methodology to regional studies is discussed.

    Objectives: To determine the incidence, severity and duration of lingual tactile and gustatory function impairments after lower third molar removal. Study Design: Prospective cohort study with intra-subject measures of 16 patients undergoing lower third molar extractions. Sensibility and gustatory functions were evaluated in each subject preoperatively, one week and one month after the extraction, using Semmes-Weinstein monofilaments and 5 different concentrations of NaCl, respectively. Additionally, all patients filled a questionnaire to assess subjective perceptions. Results: Although patients did not perceive any sensibility impairments, a statistically significant decrease was detected when Semmes-Weinstein monofilaments. This alteration was present at one week after the surgical procedure and fully recovered one month after the extraction. There were no variations regarding the gustatory function. Conclusions: Lower third molar removal under local anesthesia may cause light lingual sensibility impairment. Most of these alterations remain undetected to patients. These lingual nerve injuries are present one week after the extraction and recover one month after surgery. The taste seems to remain unaffected after these procedures. Key words:Lingual nerve, third molar, nerve injury, paresthesia, surgical extraction PMID:22322520

  9. The Relevance of Interoception in Chronic Tinnitus: Analyzing Interoceptive Sensibility and Accuracy

    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.

  10. A modified Bowen ratio method to determine sensible and latent heat fluxes

    Full Text Available The sensible heat flux (H and the latent heat flux (λE were measured above a grassland during June, 1997 (LINEX-97/1 Experiment, using the eddy covariance method (EC and the Bowen ratio/Energy balance method (BREB. The results indicate that HBREB is about (30 ± 20 Wm-2 higher than HEC, and λEBREB is about (180 ± 40 Wm-2 higher than λEEC during the daytime, and this is mainly caused by an imbalance in the closure of the surface energy balance in the BREB. In order to avoid the inaccuracies associated with the surface energy balance method, we propose a modified Bowen ratio method (MBR to determine sensible and latent heat fluxes without using the surface energy balance equation. The results and error analysis show that MBR can give more accurate results than BREB. For the MBR, a measurement system using a sonic anemometer together with temperature and humidity measurements at two levels is being recommended to obtain sensible and latent heat fluxes.

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

    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.

    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. Statistically higher

    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.

    Full Text Available Este artículo surge de un estudio hermenéutico sobre la educación del cuerpo cuyo objeto es analizar las condiciones de sensibilidad en clave pedagógica como ámbito de estudio de la Educación Corporal. En esta investigación se piensa lo sensible en relación con la educación a partir de una ruta filosófica, pedagógica y experiencial, por ello, el estudio de lo sensible se enmarca en el pensamiento filosófico de Federico Nietzsche y Gilles Deleuze, y la educación en la reflexión pedagógica de Jorge Larrosa y Fernando Bárcena. Con el análisis teórico documental que se realiza no se trata de reproducir conceptos ni ideas, sino de analizar aquellas situaciones en que la sensibilidad despliega otras maneras de pensar la educación porque la preocupación por las condiciones de sensibilidad pasa también por la necesidad de ver la estrecha relación que guarda el cuerpo y la Educación. Así, en este texto se exponen algunas prácticas corporales en clave pedagógica para hacer ver las potencias que se ejercen sobre el cuerpo. De conformidad con la dimensión simbólica del cuerpo, las prácticas corporales son, ante todo, simbologías corporales, son modos de decir del cuerpo que nos orientan para pensar una educación de lo sensible. Esta ruta experiencial del danzar, jugar y caminar permite abordar el análisis de la educación y del cuerpo desde experiencias que, quizás, están desposeídas de significado educativo, este modo de preocuparnos por lo pedagógico es una posibilidad para pensar una educación de lo sensible desde el cuerpo.

    The purpose of this work is to translate some of Robert Boyle's chemical experiments into the terms of modern chemistry. Most of the reactions involve sensible qualities, since there are on it considerable helpful tracking descriptions like heating, hissing, colour changing, etc. For a long time in the history of science, this procedure was seen as an exercise in anachronism which should be avoided at all costs. Recently many scholars have demonstrated that chemical translation can assist with historical work instead of causing confusion, and it may be very useful as a tool for the history of chemistry and for reproducing past chemical experiments.

  20. Combustion Air Pre-heating from Ash Sensible Heat in Municipal Waste Incineration Systems

    2014-01-01

    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.

    This study investigated the flux-variance relationships of temperature, humidity, and CO(2), and examined the performance of using this method for predicting sensible heat (H), water vapor (LE), and CO(2) fluxes (F(CO2)) with eddy-covariance measured flux data at three different ecosystems: grassland, paddy rice field, and forest. The H and LE estimations were found to be in good agreement with the measurements over the three fields. The prediction accuracy of LE could be improved by around 15% if the predictions were obtained by the flux-variance method in conjunction with measured sensible heat fluxes. Moreover, the paddy rice field was found to be a special case where water vapor follows flux-variance relation better than heat does. However, the CO(2) flux predictions were found to vary from poor to fair among the three sites. This is attributed to the complicated CO(2) sources and sinks distribution. Our results also showed that heat and water vapor were transported with the same efficiency above the grassland and rice paddy. For the forest, heat was transported 20% more efficiently than evapotranspiration.

    The purpose of this investigation was to obtain information from professional singers active in performing of both classical and music theater repertoire with regard to the visual/kinesthetic effect of melodic contour in musical notation as it affects vocal timbre. The evaluation of data gathered during the study indicates that there is reason to investigate the resulting postural shifts of the head and neck because they are guided by visual maps of melodic contour and its inversion. Significantly, it was discovered that the tone quality produced when a singer's head and neck postures followed the natural melodic contour of the melody was in no case considered to be the most pleasing of the conditions studied and that, in many cases, the tone quality produced when a singer's head and neck postures followed a map of the inversion of the melodic contour was judged to be much improved. The results of the study also indicate that the development of new technology for the general teaching studio, designed to address these effects, may be useful to these singers.

    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.

    A critical component of the water cycle at local, regional and global scales is evaporation from soil. Because it is very difficult to measure soil evaporation and soil moisture in the field, with the exception of using a lysimeter for local measurements, numerous model based estimation methods have been proposed. Numerical approaches that attempt to estimate evaporation rates within the top several centimeters of soil often rely of empirical and semi-empirical methods. Another less well known method to determine evaporation relies on heat pulse sensors to measure soil temperature and thermal properties. This approach does not rely on knowledge of soil hydraulic properties, effectively removing the need of several common empirical methods to define the soil surface boundary condition. The objective of this study was to integrate both the heat-pulse and sensible heat balance methods into a non-isothermal multiphase flow model in order to define the boundary conditions at the land/atmosphere interface. This model was tested using precision experimental data collected under laboratory conditions and compared to more traditional numerical modeling approaches. Experimental data was generated in a two-dimensional soil tank containing an array of sensors that allowed soil temperature, soil moisture content, and relative humidity to be collected continuously and autonomously. The soil tank was placed within a wind tunnel test facility to insure that atmospheric conditions were carefully controlled and monitored throughout the duration of the experiment. Numerical results of the model using the heat pulse and sensible heat balance methods were compared to those generated using different, more traditional modeling approaches. Results demonstrate the applicability of incorporating the heat-pulse and sensible heat balance methods in numerical approaches. Further validation was provided through a comparison of the numerical results and independently determined experimental

    This paper will address the use of animal models as a vital constituent of 'life science in the making' by focussing on the 'sensibility trials' conducted by the Swiss physiologist Albrecht von Haller (1708-1777). Haller was a pioneering figure in the early days of neurophysiological research, being not only influential for establishing animal experimentation as a viable method to gain knowledge about (human) neurological functions. He also tackled the question of sensibility as the most fundamental property of living bodies, which came to influence our conception of bodily feeling. In analysing some of his experiments on the nervous system, this paper addresses the following questions: what does sensibility or sensation signify in eighteenth-century physiology? How was it assessed or measured during experimentation? How were nervous functions 'read', i.e., how was the observable behaviour of an experimental animal interpreted? And finally: how did Haller address the differences between humans and animals in the context of his investigations?

    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.

    This study aims to describe the stated and non-stated information in the comprehension of sensibility on the part of the nursing teacher-nurse being in the teaching of Nursing. The theoretical- philosophical reference was sought in the Phenomenology of Maurice Merleau-Ponty, and the methodological support was based on the hermeneutic phenomenology of Paul Ricoeur. Nineteen nursing teachers-nurses from a Public Institution of Higher Education in the south of Brazil were interviewed during the months of November and December 2006. Data analysis revealed sensibility as the base for the development of doing, thinking, caring and doing research. Without sensibility, the relations and interactions in teaching in Nursing will be only techniques and theories of healthcare.

    The human sense is measured and analyzed by physical design factors and can be applied also for the product design. At this point of view, this paper describes the implementation process of Virtual Modeling system for a customer-oriented product. The first step implementing virtual modeling is to make a human sensibility({sup K}ansei{sup )} database -human sensibility database is constructed with the relational data of Kansei words and design factors-. The next step is extraction the design information from the human sensibility database by fuzzy inference algorithm. This design information is used for the input data for the graphic database. Virtual implementation software compounds 3D shape of product. The final product can be modified according to the customer`s requirement. (author). 13 refs., 11 figs.

  10. Analysis of the sensible heat flux from the exterior surface of buildings using time sequential thermography

    Hoyano, Akira; Asano, Kohichi; Kanamaru, Takehisa

    In this study, the distribution of surface temperature on the surface of two buildings having different characteristics was measured using a thermal infrared camera. Measurements were made in the summer, the period in Japan during which heat flux from buildings is of major interest, and again in the winter for comparison purposes. The heat characteristics of each building were obtained throughout the day by time-sequential thermography (TST), and the surface temperature of each physical element was classified according to temperature, shape, material and position. When the temperature of a surface could not be determined by an infrared camera mounted on the top of a building or a pole, temperature measurements were made using a hand-held IR camera. In addition, the sensible heat flux from each surface was calculated using TST and the surface area of each element as calculated from blueprints of the buildings.

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

    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.

    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.

    Current efforts towards Earth Science literacy in New Mexico are guided by the New Mexico Science Benchmarks [1]. We are geoscience professionals in Los Alamos, NM who believe there is an important role for non-traditional educators utilizing innovative teaching methods. We propose to further Earth Science literacy for local 3rd and 4th grade students using a kinesthetic learning approach, with the goal of fostering an interactive relationship between the students and their geologic environment. We will be working in partnership with the Pajarito Environmental Education Center (PEEC), which teaches the natural heritage of the Pajarito Plateau to 3rd and 4th grade students from the surrounding area, as well as the Family YMCA’s Adventure Programs Director. The Pajarito Plateau provides a remarkable geologic classroom because minimal structural features complicate the stratigraphy and dramatic volcanic and erosional processes are plainly on display and easily accessible. Our methodology consists of two approaches. First, we will build an interpretive display of the local geology at PEEC that will highlight prominent rock formations and geologic processes seen on a daily basis. It will include a simplified stratigraphic section with field specimens and a map linked to each specimen’s location to encourage further exploration. Second, we will develop and implement a kinesthetic curriculum for an exploratory field class. Active engagement with geologic phenomena will take place in many forms, such as a scavenger hunt for precipitated crystals in the vesicles of basalt flows and a search for progressively smaller rhyodacite clasts scattered along an actively eroding canyon. We believe students will be more receptive to origin explanations when they possess a piece of the story. Students will be provided with field books to make drawings of geologic features. This will encourage independent assessment of phenomena and introduce the skill of scientific observation. We

The results showed that performance gets better with age that it is affected by sequence extension and by number of crossings paths. The performance is better in the visual modality than in the kinesthetic one; both modalities are affected in the same way by the sequence extension and number of crossing paths. Serial position curves are marked by primacy effect; recency effect is present just in visual modality. In sequences with six and seven blocks, when considered the number of crossing paths, the performance tends to get better in a higher tax for visual modality than for kinesthetic. The results do not support a kinesthetic memory independent of the spatial system, but suggests that both components contribute to the performance in the Corsi block test.

    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.

    In the recovery process of sensibility after repair of a peripheral nerve injury of the forearm, not only age but also surgical repair techniques are of importance. If regenerating axons are misdirected, reorganisation or other adaptic processes are needed at the level of the somatosensory brain cortex. These processes are thought to be dependent on the patient's cognitive capacity. We conducted a prospective multicentre study to assess the association between cognitive capacity and recovery of sensibility after peripheral nerve damage of the forearm. Patients with a traumatic peripheral nerve lesion of the forearm and consecutive surgical repair were included. After 12 months, the patients were assessed with respect to recovery of sensibility (Semmes-Weinstein monofilaments) and cognitive capacity, with four tests assessing different aspects of cognitive functioning. Twenty-eight patients (25 male, three female; median age: 28.5 years; range: 15-79 years) with median and/or ulnar nerve injury of the forearm were included in the study. Younger age showed a positive association with sensory recovery (beta =-0.845, 95% CI: -1.456 to -0.233; p=0.01). No association was found between the cognitive-capacity tests used and sensory recovery. The present prospective study did not reveal any association between recovery of sensibility measured by Semmes-Weinstein test score and cognitive capacity. Further studies should be performed to confirm these results.

    Maogui Hu

    2015-07-01

    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.

    The accuracy in determining sensible heat flux (H) of three Kipp and Zonen large aperture scintillometers (LAS) was evaluated with reference to an eddy covariance (EC) system over relatively flat and uniform grassland near Timpas (CO, USA). Other tests have revealed inherent variability between Kipp and Zonen LAS units and bias to overestimate H. Average H fluxes were compared between LAS units and between LAS and EC. Despite good correlation, inter-LAS biases in H were found between 6% and 13% in terms of the linear regression slope. Physical misalignment was observed to result in increased scatter and bias between H solutions of a well-aligned and poorly-aligned LAS unit. Comparison of LAS and EC H showed little bias for one LAS unit, while the other two units overestimated EC H by more than 10%. A detector alignment issue may have caused the inter-LAS variability, supported by the observation in this study of differing power requirements between LAS units. It is possible that the LAS physical misalignment may have caused edge-of-beam signal noise as well as vulnerability to signal noise from wind-induced vibrations, both having an impact on the solution of H. In addition, there were some uncertainties in the solutions of H from the LAS and EC instruments, including lack of energy balance closure with the EC unit. However, the results obtained do not show clear evidence of inherent bias for the Kipp and Zonen LAS to overestimate H as found in other studies.

  11. Heat Transfer Characteristics and Performance of a Spirally Coiled Heat Exchanger under Sensible Cooling Conditions

    Wongwises, Somchai; Naphon, Paisarn

    In the present study, new experimental data on the heat transfer characteristics and the performance of a spirally coiled heat exchanger under sensible cooling conditions is presented. The spiral-coil heat exchanger consists of a steel shell and a spirally coiled tube unit. The spiral-coil unit consists of six layers of concentric spirally coiled tubes. Each tube is fabricated by bending a 9.27mm diameter straight copper tube into a spiral-coil of five turns. The innermost and outermost diameters of each spiral-coil are 67.7 and 227.6mm, respectively. Air and water are used as working fluids in shell side and tube side, respectively. A mathematical model based on the conservation of energy is developed to determine the heat transfer characteristics. There is a reasonable agreement between the results obtained from the experiment and those obtained from the model and a good agreement for the high air mass flow rate region. The results obtained from the parametric study are also discussed.

    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.

  13. 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.

  14. From sensibility to pathology: the origins of the idea of nervous music around 1800.

    Healing powers have been ascribed to music at least since David's lyre, but a systematic discourse of pathological music emerged only at the end of the eighteenth century. At that time, concerns about the moral threat posed by music were partly replaced by the idea that it could over-stimulate a vulnerable nervous system, leading to illness, immorality, and even death. During the Enlightenment, the relationship between the nerves and music was more often put in terms of refinement and sensibility than pathology. However, around 1800, this view was challenged by a medical critique of modern culture based on a model of the etiology of disease that saw stimulation as the principal cause of sickness. Music's belated incorporation into that critique was made possible by a move away from regarding music as an expression of cosmic and social order toward thinking of it as quasi-electrical stimulation, something that was intensified by the political and cultural changes unleashed by the French Revolution. For the next hundred and fifty years, nervousness caused by musical stimulation was often regarded as a fully fledged Zivilisationskrankheit, widely discussed in psychiatry, music criticism, and literature.

    The use of intravenous artificial oxytocin for augmentation of labour is very common in midwifery care in Sweden. Studies have shown that oxytocin is often administered to women in labour who have no signs of labour dystocia. It was the aim of this study to examine Swedish midwives' views on and experiences of labour augmentation in the context of normal labour. Individual interviews were carried out with 15 midwives from southern Sweden. The material was analysed using qualitative content analysis, which resulted in one theme: sense and sensibility and four main categories: permissible situations, motivating the decision, intervening in the birth process and iatrogenic awareness. The results showed that midwives expressed ambiguity about augmentation of labour. They were of the opinion that oxytocin was used very often and sometimes unnecessarily. There is awareness that interventions to augment labour can result in undesirable effects on the birth process. Despite this, deeper discussion of this problem was avoided in the interviews. Further research should focus on the process involved when midwives weigh pros and cons when deciding to augment labour. More knowledge is also needed about the barriers for optimal care in labour that are inherent in health-care systems.

    2015-01-01

    Famed for his collection of drawings of naturalia and his thoughts on the relationship between painting and natural knowledge, it now appears that the Bolognese naturalist Ulisse Aldrovandi (1522-1605) also pondered specifically color and pigments, compiling not only lists and diagrams of color terms but also a full-length unpublished manuscript entitled De coloribus or Trattato dei colori. Introducing these writings for the first time, this article portrays a scholar not so much interested in the materiality of pigment production, as in the cultural history of hues. It argues that these writings constituted an effort to build a language of color, in the sense both of a standard nomenclature of hues and of a lexicon, a dictionary of their denotations and connotations as documented in the literature of ancients and moderns. This language would serve the naturalist in his artistic patronage and his natural historical studies, where color was considered one of the most reliable signs for the correct identification of specimens, and a guarantee of accuracy in their illustration. Far from being an exception, Aldrovandi's 'color sensibility'spoke of that of his university-educated nature-loving peers.

  17. Feasibility of a novel functional sensibility test as an assisted examination for determining precision pinch performance in patients with carpal tunnel syndrome.

    Full Text Available To understand the feasibility of a novel functional sensibility test for determining precision pinch performance in patients with carpal tunnel syndrome, this study investigates the validity, sensitivity and specificity of functional sensibility derived from a pinch-holding-up activity (PHUA test. Participants include 70 clinically defined carpal tunnel syndrome (CTS patients with 119 involved hands and 70 age- and gender-matched controls. To examine the discriminating ability of the functional sensibility test, the differences in the ability of pinch force adjustments to the inertial load of handling object between CTS and control subjects are analyzed. The results of functional sensibility are correlated with the severity of CTS to establish concurrent validity. The receiver operating characteristic (ROC curve is constructed to demonstrate the accuracy of the proposed test. The functional sensibility score significantly discriminates the patients and control groups (respectively, 12.94±1.72 vs. 11.51±1.15N in peak pinch force (FPPeak, p<0.001; 2.92±0.41 vs. 2.52±0.24 in force ratio, p<0.001 and is moderately correlated (r = 0.42-0.54, p<0.001 with the results of traditional sensibility tests (touch-pressure threshold and two-point discrimination test. In addition, there is a statistical difference in the results of functional sensibility (p<0.001 among the subgroups of CTS severity based on electrophysiological study. The sensitivity and specificity are 0.79 and 0.76, respectively, for the functional sensibility test. The areas under the ROC curve are 0.85 and 0.80 for the force ratio and FPPeak, respectively. In conclusion, the functional sensibility test could be feasibly used as a clinical tool for determining both the sensibility and precision pinch performance of hands for the patients with CTS.

    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.

  19. 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.

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

    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?

  1. A system for vertical profile measurements of sensible heat and chemical concentrations near the ground surface

    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.

    Full Text Available Actualmente se abre un mundo de posibilidades por los senderos de una crisis epistémica-social, que permea los espacios universitarios y cotidianos. Urge por lo señalado, estudiar lo académico en el contexto universitario venezolano y dentro de ello la investigación, la reflexión crítica de la práctica y la formación profesional. Son estos aspectos que han sufrido derivas y deben ser repensados en un nuevo marco de sensibilidades. Algunos autores relevantes que fundamentan la resemantización de la relación entre universidad y comunidad son: Foucault (1970, Martínez (2000, Téllez (2001, Maffesoli (2004, Larrosa (2003 y Dussel (2001. 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.

    Full Text Available The accuracy in determining sensible heat flux (H of three Kipp and Zonen large aperture scintillometers (LAS was evaluated with reference to an eddy covariance (EC system over relatively flat and uniform grassland near Timpas (CO, USA. Other tests have revealed inherent variability between Kipp and Zonen LAS units and bias to overestimate H. Average H fluxes were compared between LAS units and between LAS and EC. Despite good correlation, inter-LAS biases in H were found between 6% and 13% in terms of the linear regression slope. Physical misalignment was observed to result in increased scatter and bias between H solutions of a well-aligned and poorly-aligned LAS unit. Comparison of LAS and EC H showed little bias for one LAS unit, while the other two units overestimated EC H by more than 10%. A detector alignment issue may have caused the inter-LAS variability, supported by the observation in this study of differing power requirements between LAS units. It is possible that the LAS physical misalignment may have caused edge-of-beam signal noise as well as vulnerability to signal noise from wind-induced vibrations, both having an impact on the solution of H. In addition, there were some uncertainties in the solutions of H from the LAS and EC instruments, including lack of energy balance closure with the EC unit. However, the results obtained do not show clear evidence of inherent bias for the Kipp and Zonen LAS to overestimate H as found in other studies.

    Energy balance is a major determinant of Earth surface temperature and climate. However, the physics of energy balance computations are complex and vary in space and in time. Most of the data available on the energy balance of non-agricultural systems is from local measurements, only representative of the area around the measuring point. To overcome this, remote sensing techniques have been widely used, particularly in studies on the temporal land-cover changes and on their influences on the energy and water balances. Several remote sensors with different spatial, temporal and spectral resolutions have been used to understand these processes. In many applications, the main objective is to understand how landscape's changes over time can influence regional climate. Orbital information enables the analysis of the spatial and temporal features of the Earth's surface, and to understand the interactions between different land-cover types with topography, atmospheric and anthropogenic action. However, to test for accuracy and precision, data from satellite sensors and their derivatives need to be compared with ground-level field data. This study evaluates and tests sensible heat flux data obtained from the SEBAL algorithm using images by Thematic Mapper (TM) sensor aboard Landsat 5 satellite. These sensible heat flux data were compared with those of two ground level experiments, with the Eddy Covariance technique, in Évora and Coruche, Portugal. The footprints of the sensible heat flux measurements were calculated for six scenes of sensor TM, allowing the comparison between satellite data and surface flux data. Results showed a high correlation between sensible heat flux data derived from remote sense and ground-level measurements (R2=0.94). We conclude that the remote sensing technique is useful in estimating this energy balance component and may contribute to the understanding of vegetation dynamics.

    The vertical mixing behaviour of large deep lakes as e.g. Lake Constance is reflecting the long-term meteorological conditions and therefore is likely to be sensible to climate change. Today, Lake Constance does not mix completely every year, but only once in 2-3 years, which leads to the typical saw-tooth pattern in the deep water temperature. Whether complete mixing does occur is not only depending on the meteorological conditions in the respective winter period, but also on the thermal conditions in the lake and hence on the meteorological conditions in the preceding years. The lake's response to climate change thus depends on the temperature increase itself as well as on its gradient and on the inter-annual variability of the meteorological variables. Last year we showed first steps towards a model system to evaluate possible effects of climate change on Lake Constance: The Vector-Autoregressive Weathergenerator VG produces time series of meteorological data, which are used as boundary conditions for the 3D hydrodynamic lake model ELCOM (Centre of Water Research, University of Western Australia). As VG gives the opportunity to change mean and variability of selected variables, "What if?" - scenarios for process understanding can be performed. The time scales of variability turned out to be a critical point in the artificial time series for modelling the hydrodynamics of Lake Constance, as the big water body integrates over time and thus the hydrodynamics overlook the variability of air temperature on short time scales. Therefore, VG was developed further, especially with respect to the time scales of variability. While for heat input, the time scale of several days to weeks seems to be more important, wind and, when biology is modelled, short-wave radiation should be given at a sub-daily timestep. Besides producing user-defined scenario time-series, VG can also be used to stochastical downscale output of global climate model IPCC scenarios for lake modelling

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

    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.

  8. Turbulent Fluxes of Sensible Heat Measured by Research UAV 'M2AV Carolo'

    Research aircraft equipped for turbulence measurements in the atmospheric boundary layer (ABL) are suitable platforms to measure area-representative mean values and statistical moments of second order - like variance, spectral distribution and turbulent fluxes - in situ i.e. without the use of any theoretical assumptions. Since manned research aircraft are expensive the use of small unmanned aerial vehicle (UAV) or mini aerial vehicles (MAV) is attractive. Such research UAV are able to measure vertical profiles of the lower troposphere, for instance. The next, more challenging league is the measurement of the turbulent fluctuations of the wind vector and simultaneously at least one scalar quantity in order to calculate turbulent fluxes using eddy covariance. To do this, fast and accurate sensors are required, with small weight, small dimensions and small power consumption, in order to be operated on a small research UAV. Beside absolute and relative measurement accuracy, the response time of the sensors has to be short (in the order of several 10 Hz) to resolve turbulent eddies also in stable stratification (i.e. sub-metre range). Since light, small and fast sensors for air humidity and trace gases are not available currently, the first step is to measure the vertical flux of sensible heat H. Beside a slow (about 1 Hz) water vapour sensor, the automatically operating meteorological mini aerial vehicles (M2AV) are equipped with two temperature sensors and a wind measurement unit. One of the temperature sensors is slow but offers a high absolute accuracy, while the fast sensor (up to 100 Hz) has a high relative accuracy but is unstable in time. The two signals are blended using a complementary filter. The wind vector can be calculated using the inertial velocity (aircraft speed relative to the earth) and the true airspeed (aircraft speed relative to the airflow). The true airspeed of M2AV is computed from five-hole-probe pressure measurements whereas the aircraft

    Full Text Available Abstract Background Several clinical measures of sensory and motor function are used alongside patient-rated questionnaires to assess outcomes of carpal tunnel decompression. However there is a lack of evidence regarding which clinical tests are most responsive to clinically important change over time. Methods In a prospective cohort study 63 patients undergoing carpal tunnel decompression were assessed using standardised clinician-derived and patient reported outcomes before surgery, at 4 and 8 months follow up. Clinical sensory assessments included: touch threshold with monofilaments (WEST, shape-texture identification (STI™ test, static two-point discrimination (Mackinnon-Dellon Disk-Criminator and the locognosia test. Motor assessments included: grip and tripod pinch strength using a digital grip analyser (MIE, manual muscle testing of abductor pollicis brevis and opponens pollicis using the Rotterdam Intrinsic Handheld Myometer (RIHM. The Boston Carpal Tunnel Questionnaire (BCTQ was used as a patient rated outcome measure. Results Relative responsiveness at 4 months was highest for the BCTQ symptom severity scale with moderate to large effects sizes (ES = -1.43 followed by the BCTQ function scale (ES = -0.71. The WEST and STI™ were the most responsive sensory tests at 4 months showing moderate effect sizes (WEST ES = 0.55, STI ES = 0.52. Grip and pinch strength had a relatively higher responsiveness compared to thenar muscle strength but effect sizes for all motor tests were very small (ES ≤0.10 or negative indicating a decline compared to baseline in some patients. Conclusions For clinical assessment of sensibility touch threshold assessed by monofilaments (WEST and tactile gnosis measured with the STI™ test are the most responsive tests and are recommended for future studies.

    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

    The increasing ice-free area during late summer has transformed the Arctic to a climate system with more dynamic boundary layer (BL) clouds and seasonal sea ice growth. The open-ocean sensible heat flux, a crucial mechanism of excessive ocean heat loss to the atmosphere during the fall freeze season, is speculated to play an important role in the recently observed cloud cover increase and BL instability. However, lack of observations and understanding of the resilience of the proposed mechanisms, especially in relation to meteorological and interannual variability, has left a poorly constrained BL parameterization scheme in Arctic climate models. In this study, we use multiyear Japanese cruise-ship observations from RV Mirai over the open Arctic Ocean to characterize the surface sensible heat flux (SSHF) during early fall and investigate its contribution to BL turbulence. It is found that mixing by SSHF is favored during episodes of high surface wind speed and is also influenced by the prevailing cloud regime. The deepest BLs and maximum ocean-atmosphere temperature difference are observed during cold air advection (associated with the stratocumulus regime), yet, contrary to previous speculation, the efficiency of sensible heat exchange is low. On the other hand, the SSHF contributes significantly to BL mixing during the uplift (low pressure) followed by the highly stable (stratus) regime. Overall, it can explain 10 of the open ocean BL height variability, whereas cloud-driven (moisture and radiative) mechanisms appear to be the other dominant source of convective turbulence. Nevertheless, there is strong interannual variability in the relationship between the SSHF and the BL height which can be intensified by the changing occurrence of Arctic climate patterns, such as positive surface wind speed anomalies and more frequent conditions of uplift. This study highlights the need for comprehensive BL observations like the RV Mirai for better understanding and

    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.

    Full Text Available Este texto es un artículo de reflexión. Argumenta que la educación estética es un promisorio camino para promover uno de los más importantes objetivos de la educación: la formación integral. A partir de las Cartas sobre la educación estética del hombre, del filósofo y poeta Friedrich Schiller, se muestra que dos son los rasgos que pueden definir la vocación intelectual del hombre: el impulso formal y el impulso sensible. El primero, recoge la necesidad humana de racionalidad, esto es, la vocación a encontrar y construir abstracciones y regularidades del mundo, de fundirse en lo universal; el segundo, la inclinación de las personas a buscar emociones que aviven su sensibilidad y pasiones, de mantenerse como seres singulares. Descrito el impulso formal y el impulso sensible como las dos cualidades que holísticamente configuran las potencialidades intelectuales humanas, se muestra que la apreciación de lo bello, en términos de Schiller: la Forma viva, en tanto cultiva equilibradamente ambos ímpetus humanos, fomenta la educación integral en las personas.

    ENGLISH ABSTRACT: Coherency is becoming a necessary feature for any risk measure, and now is an acceptable tool in risk management to assess the risk measures. For example, recent studies have strongly criticised VaR-based models for not providing a coherent risk measure. Because of such acceptance, it is important to improve the efficiency of the touchstone for evaluating risk measures in order to achieve a fairer assessment. This is just the challenge that this paper seeks to address. This goal is achieved on the one hand by doing some simplifications in axioms of coherency without losing their major financial points, and on the other hand by removing the paradox between two of the axioms. The new concept is called ‘sensible coherency’, and the risk measure that satisfies the four new simplified and corrected axioms will be ‘sensibly coherent’. Finally, the new axioms are applied to a particular type of lower partial moments as a case study.

    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

In fact, Valéry kept returning to the great renaissance phenomenon of Leonardo, in his twisted Introduction à la Méthode de Léonard de Vinci (1894, rewritten some 25 years later with Note et digression (1919, as well in his staging of philosophers and artists in Léonard et les philosophes (1929.

  5. 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.

    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

    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 /sup 6/LiH annulus. The response of interest is the /sup 6/Li tritium production per source neutron, T/sub 6/. 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 /sup 6/Li (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 T/sub 6/ uncertainties. The results of Path A and Path B were total uncertainties in T/sub 6/ 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

    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

    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.

    Relations between an early interest in violent fantasy and children's social understanding, antisocial and emotional behavior, and interactions with friends were investigated in 40 "hard-to-manage" preschoolers and 40 control children matched for gender, age, and school and ethnic background. Children were filmed alone in a room with a friend, and tested on a battery of cognitive tests, including false-belief, executive function, and emotion understanding tasks. Teachers reported on their friendship quality. At age 6 years, the children's understanding of the emotional consequences of antisocial and prosocial actions was studied. The hard-to-manage group showed higher rates of violent fantasy; across both groups combined, violent fantasy was related to poor executive control and language ability, frequent antisocial behavior, displays of anger and refusal to help a friend, poor communication and coordination of play, more conflict with a friend, and less empathic moral sensibility 2 years later. The usefulness of a focus on the content of children's pretend play-in particular, violent fantasy-as a window on children's preoccupations is considered.

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.

    Introduccion. Tham y Tegner propusieron el Baking Tray Task (BTT) como una prueba de evaluacion rapida y simple para la deteccion de negligencia espacial. No obstante, apenas existen estudios que hayan examinado su validez como prueba diagnostica. Objetivo. Analizar la validez diagnostica del BTT, midiendo su especificidad y sensibilidad, en una muestra de sujetos con ictus hemisfericos derechos. Sujetos y metodos. Cuarenta y ocho pacientes con lesiones vasculares hemisfericas derechas distribuidos en dos grupos (grupo negligencia, n = 35; grupo no negligencia, n = 13) en funcion de las puntuaciones obtenidas en una bateria de exploracion visuoespacial. La ejecucion de los participantes en el BTT se comparo con un grupo control sano (n = 12). Resultados. Los resultados mostraron una alta sensibilidad del BTT, pero una baja especificidad. Ocho de los 13 integrantes del grupo no negligencia obtuvieron un rendimiento en el BTT sugestivo de negligencia. Conclusiones. El BTT se muestra como un test sensible para la deteccion de la negligencia espacial. Sin embargo, basandonos en su baja especificidad, no es recomendable su uso aislado como prueba unica de diagnostico.

  15. In-situ Modelisation of a Greenhouse Climate Including Sensible Heat, Water Vapour and CO2 Balances

    Full Text Available While thermal structures such as greenhouses are complex to model under transient conditions because of coupled heat and mass (H2O and CO2 exchanges between their different parts, systems theory allows a simple analysis of the input/output behaviour of the model. In particular, parameters of the reduced dynamic models can be derived from in-situ measurements on these systems. This paper describes an application of the systems approach to a greenhouse climate model which incorporates CO2 balance, crop transpiration and photosynthesis and the effects of heating, CO2 enrichment, natural ventilation and evaporative cooling. In a first stage, system parameters such as the equivalent thermal mass, the wind dependent coefficient of natural ventilation and the various heat exchange coefficients were identified in situ from sequences of input-output data concerning the heat and water vapour balance, recorded over the crop production period from December to July. Good agreement between measured and computed values of air temperature, air humidity was observed. In a second stage, we have considered simultaneously the sensible heat, water vapour and CO2 exchanges and tested the model against experimental data measured using a commercial greenhouse climate control computer. The identified values of the physical and physiological parameters are close the theoretical values and the accuracy of temperature, humidity and CO2 content is rather good.

    . 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.

    Irrigation, which constitutes ˜ 70 % of the total amount of freshwater consumed by the human population, is significantly impacting land-atmosphere fluxes. In this study, using the improved Community Land Model version 4.5 (CLM4.5) with an active crop model, two high-resolution (˜ 1 km) simulations investigating the effects of irrigation on latent heat (LH), sensible heat (SH), and carbon fluxes (or net ecosystem exchange, NEE) from land to atmosphere in the Heihe River basin in northwestern China were conducted using a high-quality irrigation dataset compiled from 1981 to 2013. The model output and measurements from remote sensing demonstrated the capacity of the developed models to reproduce ecological and hydrological processes. The results revealed that the effects of irrigation on LH and SH are strongest during summer, with a LH increase of ˜ 100 W m-2 and a SH decrease of ˜ 60 W m-2 over intensely irrigated areas. However, the reactions are much weaker during spring and autumn when there is much less irrigation. When the irrigation rate is below 5 mm day-1, the LH generally increases, whereas the SH decreases with growing irrigation rates. However, when the irrigation threshold is in excess of 5 mm day-1, there is no accrued effect of irrigation on the LH and SH. Irrigation produces opposite effects to the NEE during spring and summer. During the spring, irrigation yields more discharged carbon from the land to the atmosphere, increasing the NEE value by 0.4-0.8 gC m-2 day-1, while the summer irrigation favors crop fixing of carbon from atmospheric CO2, decreasing the NEE value by ˜ 0.8 gC m-2 day-1. The repercussions of irrigation on land-atmosphere fluxes are not solely linked to the irrigation amount, and other parameters (especially the temperature) also control the effects of irrigation on LH, SH, and NEE.

    We study the spatial variability impact of surface sensible heat flux (SHF) on the convective boundary layer (CBL), using the Weather Research and Forecasting (WRF) model in large eddy simulation (LES) mode. In order to investigate the response of the CBL to multi-scale feature of the surface SHF field over a local area of several tens of kilometers or smaller, an analytic surface SHF map is crated as a function of the chosen feature. The spatial variation in the SHF map is prescribed with a two-dimensional analytical perturbation field, which is generated by using the inverse transform technique of the Fourier series whose coefficients are controlled, of which spectrum to have a particular slope in the chosen range of wavelength. Then, the CBL responses to various SHF heterogeneities are summarized as a function of the spectral slope, in terms of mean structure, turbulence statistics and cross-scale processes. The range of feasible SHF heterogeneities is obtained from the SHF maps produced by a land surface model (LSM) of the WRF system. The LSM-derived SHF maps are a function of geographical data on various resolutions. Based on the numerical experiment results with the surface heterogeneities in the range, we will discuss the uncertainty in the SHF heterogeneity and its impact on the atmosphere in a numerical model. Also we will present the range of spatial scale of the surface SHF heterogeneity that significantly influence on the whole CBL. Lastly, we will report the test result of the hypothesis that the spatial variability of SHF is more representative of surface thermal heterogeneity than is the latent heat flux over the local area of several tens of kilometers or smaller.

  3. Mechanical sensibility of nociceptive and non-nociceptive fast-conducting afferents is modulated by skin temperature.

    The ability to distinguish mechanical from thermal input is a critical component of peripheral somatosensory function. Polymodal C fibers respond to both stimuli. However, mechanosensitive, modality-specific fast-conducting tactile and nociceptor afferents theoretically carry information only about mechanical forces independent of the thermal environment. We hypothesize that the thermal environment can nonetheless modulate mechanical force sensibility in fibers that do not respond directly to change in temperature. To study this, fast-conducting mechanosensitive peripheral sensory fibers in male Sprague-Dawley rats were accessed at the soma in the dorsal root ganglia from T11 or L4/L5. Neuronal identification was performed using receptive field characteristics and passive and active electrical properties. Neurons responded to mechanical stimuli but failed to generate action potentials in response to changes in temperature alone, except for the tactile mechanical and cold sensitive neurons. Heat and cold ramps were utilized to determine temperature-induced modulation of response to mechanical stimuli. Mechanically evoked electrical activity in non-nociceptive, low-threshold mechanoreceptors (tactile afferents) decreased in response to changes in temperature while mechanically induced activity was increased in nociceptive, fast-conducting, high-threshold mechanoreceptors in response to the same changes in temperature. These data suggest that mechanical activation does not occur in isolation but rather that temperature changes appear to alter mechanical afferent activity and input to the central nervous system in a dynamic fashion. Further studies to understand the psychophysiological implications of thermal modulation of fast-conducting mechanical input to the spinal cord will provide greater insight into the implications of these findings.

    Full Text Available During the Convective and Orographically induced Precipitation Study (COPS, a scanning Doppler lidar was deployed at Achern, Baden-Wüttemberg, Germany from 13th June to 16th August 2007. Vertical velocity profiles ('rays' through the boundary layer were measured every 3 seconds with vertical profiles of horizontal wind velocity being derived from performing azimuth scans every 30 minutes. During Intense Observation Periods radiosondes were launched from the site. In this paper, a case study of convective boundary layer development on 15th July 2007 is investigated. Estimates of eddy dissipation rate are made from the vertically pointing lidar data and used as one input to the velocity-temperature co-variance equation to estimate sensible heat flux. The sensible heat flux values calculated from Doppler lidar data are compared with a surface based energy balance station and output from the Weather Research and Forecasting (WRF model.

    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.

    Full Text Available This article proposes a combined perspective of Greenblatt’s famous concept of ‘self-fashioning’ and Reddy’s well-known theory of ‘emotives’ as a possible new approach to the study of Dutch political culture, and more specifically to political figures. 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’.

Als eerste verkenning van de mogelijkheden van deze gecombineerde benadering wordt een analyse gemaakt van de manier waarop de Nederlandse staatsman Rutger Jan Schimmelpenninck emoties inzette voor de cultivering van zijn politieke imago.

    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

    While the large-scale climate conditions play an important role in shaping the environment in which glaciers exist, the mass and energy balance of each individual glacier are dictated by local conditions. Given the complex mountain topography around alpine glaciers, it is not trivial to find a direct link between the large-scale atmospheric motions and the local-scale weather conditions at an individual glacier. Non-local dynamic effects due to the surrounding complex topography can significantly modify the spatial variability of exchange processes, either by small scale circulations or episodic entrainment of heat and momentum by burst events. Motivated by the fact that distributed glacier models strongly rely on the quality of high resolution forcing data to adequately represent the glacier wide ablation and accumulation processes, the present study investigates (i) whether non-local topographic effects have a significant impact on the spatial distribution of turbulent sensible heat fluxes (local microclimates) over alpine glaciers, and (ii) how much variability is smoothed out when using linearly interpolated fields together with the commonly used bulk approach. To answer these questions, we perform highly resolved and properly designed case experiments by Large-Eddy Simulations with real topography to determine the impact of topographic flow features on the spatial variability of the surface sensible heat flux and compare the fields with those derived with the bulk approach. The analysis shows that there is a significant spatial variability of the mean fluxes with values ranging from -10 Wm-2 to -120 Wm-2. Since the sensible heat flux can make up to 40% of the total melting on mid-latitude alpine valley glaciers, the heterogeneity of the fluxes can substantially dictate the local melting rates. When estimating the glacier-wide surface heat fluxes on the basis of point-measurements and the bulk approach, a considerable amount of spatial information is lost. All

    This paper explores the unique mind of the twentieth- century American artist Joseph Cornell, known for his boxes and collages made with "found" materials. The author interpolates reflections upon Cornell with vignettes from the treatment of a young child, speculating that certain individuals may possess a constellation of vulnerabilities/sensitivities that constitute what is referred to as a "cosmic" sensibility. It is suggested that such an orientation can lead variously to anxieties and separation problems, as well as (or in addition to) intellectual and/or artistic giftedness. The outcome of such dynamics would depend on a complex interplay of temperament, circumstance, and relational attunement.

  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

    By utilizing the data of the intensive observation period (May-June, 2000) of Dunhuang land-surface process field experiment that belongs to "Land-atmosphere Interactive Field Experiment over Arid Region of Northwest China", the bulk momentum transfer coefficient Cd and bulk sensible heat transfer coefficient Ch between surface and atmosphere over desert and Gobi in the arid region are determined according to three different methods. The result shows that, though these bulk transfer coefficients are different, they are in the same order. Especially, the means of Cd and Ch are close. Moreover, through analyzing the wind direction, the interference of the building near the observational station with the data is eliminated. From this, the relation between the bulk transfer coefficients and the bulk Richardson number and the range of the typical values of the bulk transfer coefficients over desert and Gobi in the typical arid region are obtained.

    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

    Full Text Available In this paper we will present on the one hand, the data about women’s presence in animal rights movements in Spain; on the other hand, we will try to find explanatory frameworks that clarify which are the link that connects feminist sensibility to animal rights sensibility. We have made a survey on the percentage of women in the membership of the most important animal rights defense organizations in Spain and, with these results, we have made a review of different theoretical frameworks which can explain this significant gender orientation in animal welfare defense. Finally, we claim that there is a bond between patriarchal ideology and ecological exploitation, in the sense that both share domination and gender oppression. In this sense, the sensitivity to animal rights mobilizes moral feelings of fraternity with nature.En este trabajo se analizan, por una parte, los datos sobre la presencia de las mujeres en los movimientos de derechos de los animales en el estado español; por otro lado, tratamos de encontrar marcos explicativos que aclaren cuál es el vínculo que conecta la sensibilidad feminista con la sensibilidad animalista. Hemos realizado un sondeo sobre el porcentaje de mujeres entre los miembros de las organizaciones animalistas más importantes de España y, con estos resultados, hemos hecho una revisión de los diferentes marcos teóricos que pueden explicar esta significativa orientación de género en la defensa del bienestar animal. Por último, defendemos que hay un vínculo entre la ideología patriarcal y la explotación ecológica, en tanto que ambos comparten la dominación y la opresión de género. En este sentido, la sensibilidad animalista movilizaría sentimientos morales de fraternidad con la naturaleza.

    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.

    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

    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 an Arctic landscape. 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 formula 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 untypical 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 only the use of a hydrodynamic three-layer temperature-profile model achieves enough accuracy for heat flux calculations as it reliably reproduces the temporal variability of the surface temperature.

    The impact of surface sensible heating over the Tibetan Plateau (SHTP) on the western Pacific subtropical high (WPSH) with and without air-sea interaction was investigated in this study. Data analysis indicated that SHTP acts as a relatively independent factor in modulating the WPSH anomaly compared with ENSO events. Stronger spring SHTP is usually followed by an enhanced and westward extension of the WPSH in summer, and vice versa. Numerical experiments using both an AGCM and a CGCM confirmed that SHTP influences the large-scale circulation anomaly over the Pacific, which features a barotropic anticyclonic response over the northwestern Pacific and a cyclonic response to the south. Owing to different background circulation in spring and summer, such a response facilitates a subdued WPSH in spring but an enhanced WPSH in summer. Moreover, the CGCM results showed that the equatorial low-level westerly at the south edge of the cyclonic anomaly brings about a warm SST anomaly (SSTA) in the equatorial central Pacific via surface warm advection. Subsequently, an atmospheric Rossby wave is stimulated to the northwest of the warm SSTA, which in turn enhances the atmospheric dipole anomalies over the western Pacific. Therefore, the air-sea feedbacks involved tend to reinforce the effect of SHTP on the WPSH anomaly, and the role of SHTP on general circulation needs to be considered in a land-air-sea interaction framework.

    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.

    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.

In this chapter, I will discuss both of these experiences, presenting my thoughts regarding the Chinese Room argument and Artificial Intelligence (AI) in between.

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.

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.

    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.

    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.

Twelve dry Morada Nova ewes with an average of 3 ± 1.2 years old and average body weight of 32.76 ± 3.72 kg were used in a Latin square design 12 × 12 (12 days of records and 12 schedules). Tidal volume, respiratory rate, expired air temperature, and partial vapor pressure of the expired air were obtained from the respiratory facial mask and using a physiological measurement system. Ewes were evaluated from 0700 to 1900 h in each day under shade. A simple nonlinear model to estimate tidal volume as a function of respiratory rate was developed. Equation to estimate the expired air temperature was built, and the ambient air temperature was the best predictor together with relative humidity and ambient vapor pressure. In naturalized Morada Nova sheep, respiratory convection seems to be a mechanism of heat transfer of minor importance even under mild air temperature. Evaporation from the respiratory system increased together with ambient air temperature. At ambient air temperature, up to 35 °C respiratory evaporation accounted 90 % of the total heat lost by respiratory system, on average. Models presented here allow to estimate the heat flow from the respiratory tract for Morada Nova sheep bred in tropical region, using easily measured physiological and environmental traits as respiratory rate, ambient air temperature, and relative humidity.

    对汉信码所采用的RS纠错码的纠错方法进行研究,探讨了如何采用MATLAB工具实现汉信码中RS码的编码和译码,并对其纠正随机错误和突发错误的性能进行了仿真,得到不同的误码率-信噪比曲线,这些曲线反映了RS码纠错能力与码长及校验位长度的关系.研究结果为汉信码的工程实现和评估汉信码传输可靠性提供了理论依据.%The error correcting method using Reed-Solomon ( RS ) code applied to Chinese sensible code is studied. The way of how to achieve the encoding and decoding of RS code used in Chinese sensible code by MATLAB is introduced. The performance simulation of correcting random errors and burst errors are implemented by MATLAB. The different curves of bit error rate and signal noise are obtained through the simulation, and these curves reflect the relationship between error correcting performance and the code length. The results provide theoretical basis for the engineering realization and the transmission reliability evaluation of Chinese sensible code.

    Traditionally, cooling load is simply divided into sensible heat load and latent heat load. The difference among the reduction of cooling load, reduction of energy consumption and efifcient handling of cooling load is not understood quite well, which is not good for constructing more energy-efifcient air-conditioning system. Based on the traditional classiifcation of cooling load, the idea of grading sensible heat load is proposed, where the sensible load is classiifed into high-grade, mid-grade and low-grade load according to its temperature. The idea show how to reduce the high-grade load and how to convert the high-grade load into mid-grade or low-grade load. Also the idea is employed to analyze the process of sensible heat load forming, converting, and handling. The difference between the reduction of cooling load and conversion between different grades is clearly distinguished by the idea. The grading of sensible heat load will help to build more energy-efifcient air-conditioning system.%传统空调系统只将空调负荷分为热负荷和湿负荷,且对负荷降低、能耗降低和负荷高效处理之间的差别认识不深入,不利于构思更高效的空调系统形式。在热湿负荷分类的基础上,提出了显热负荷的品位分级思想,即将负荷按温度分成高品位负荷、中品位负荷和低品位负荷。通过运用几种不同空调方式,展示了利用该思想如何更有效地减少高品位负荷数量以及如何将部分传统的高品位负荷转化成中品位或低品位负荷,从而降低空调系统的能耗;另一方面可更为清晰地分析显热负荷从形成、转移到被处理的过程,厘清了负荷降低与负荷转移之间的关系。显热负荷分级的思想将为新型空调系统形式的构建提供理论指导。

    Full Text Available The character Voyleano has models in the suicide Werther, by Goethe, and in the death-desiring Tediato in the Lugubrious Nights, by Cadalso. The creation of the figure of Voyleano depends on the new sensibility of the Enlightenment, romantic cosmic grief, and the exaltation of romantic psychology. In the novel by Vayo the Napoleonic invasion of Spain is depicted, and this atmosphere lends itself to libertine seductions, betrayals, great disillusionments, and the loss of faith. Voyleano, like don Quijote, like Julien Sorel, like Emma Bovary, and like several characters from Larra and Mesonero Romanos has sought a model or logos in an earlier character. After don Quijote Voyleano is the first of all of them. Voyleano considers the physical act of suicide lacking in nobility and cowardly, and although he is inspired by Werther, he is attracted to Tediato’s way of committing suicide while avoiding the physical act of suicide.El personaje Voyleano tiene modelos en el suicida Werther, de Goethe, y en el deseoso de morir Tediato de las Noches lúgubres, de Cadalso. Entran en la confección de la figura de Voyleano la nueva sensibilidad de la Ilustración, el dolor cósmico romántico y la exaltación de la psicología romántica. En la novela de Vayo se vive la invasión napoleónica de España, y tal ambiente se presta a seducciones libertinas, traiciones, grandes desilusiones y pérdida de la fe. Voyleano, como don Quijote, como Julien Sorel, como Emma Bovary y como varios personajes de Larra y Mesonero Romanos ha buscado un modelo o logos en un personaje anterior. Después de don Quijote, Voyleano es el primero de todos ellos. A Voyleano le parece poco noble y cobarde el acto físico del suicidio, y aunque se inspira en Werther, le atrae en Tediato el modo de suicidarse evitando el acto físico del suicidio.

    By using the tower observation data on wind, temperature, and humidity in the semi-arid climate and environment observatory of Lanzhou University from Dec 2006 to Feb 2007, the friction velocity, friction temperature, turbulent momentum flux and sensible heat flux were analyzed with the gradient calculation method; then the flux value was compared with the result of the eddy-covariance flux measurement in Feb 2007. The results show that the turbulent momentum flux and sensible heat flux have a close connection with the atmospheric stability, and they both decrease with decrease of the stability. They all have obvious diurnal variation, the biggest appears at noon and the smallest at night. The momentum fluxes are always downward transfering regardless of the stability, but sensible heat fluxes are upward transfering at daytime, and downward transfering at night. The monthly mean momentum flux and sensible heat flux are the smallest in Dec, the largest in Feb, and the monthly mean momentum flux is far less than that of the sensible heat flux. In Feb, the slope of turbulent momentum flux scatter diagram is 1.096, and correlation coefficient is 0.761; the slope of sensible heat flux scatter diagram is 1.015, and correlation coefficient is 0.957.%利用兰州大学半干旱气候与环境观测站2006年12月-2007年2月铁塔观测所得的7层风、温、湿资料,采用梯度法计算了摩擦速度、摩擦温度、湍流动量通量和感热通量,并将2007年2月的通量计算值与开路涡度协方差系统观测值进行比较.结果表明:动量通昔和感热通量与稳定度有密切关系.均随稳定度的增加而减小.动量通量和感热通量均有明显的日变化,中午时段最大,夜晚最小.动量通昔无论在何种稳定度条件下均是由上向下输送;感热通量白天均是由下向上输送,夜间均是由上向下输送.在冬季,动量通量和感热通量的月平均值都是在12月最小,在2月最大,且动量通量

    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)

    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.

    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.

    2011-05-01

    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.

  17. Modeling DNA structure and processes through animation and kinesthetic visualizations

    Hager, Christine

    There have been many studies regarding the effectiveness of visual aids that go beyond that of static illustrations. Many of these have been concentrated on the effectiveness of visual aids such as animations and models or even non-traditional visual aid activities like role-playing activities. This study focuses on the effectiveness of three different types of visual aids: models, animation, and a role-playing activity. Students used a modeling kit made of Styrofoam balls and toothpicks to construct nucleotides and then bond nucleotides together to form DNA. Next, students created their own animation to depict the processes of DNA replication, transcription, and translation. Finally, students worked in teams to build proteins while acting out the process of translation. Students were given a pre- and post-test that measured their knowledge and comprehension of the four topics mentioned above. Results show that there was a significant gain in the post-test scores when compared to the pre-test scores. This indicates that the incorporated visual aids were effective methods for teaching DNA structure and processes.

    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.

    Experimental relationships have been established between the blackening of emulsions by impinging ions and the following parameters: number, mass and energy of impinging particles. Mean energy ions (about twenty keV) give rise to a latent image probably made of small specks of metallic silver located at the surface or in the bulk of the silver halide grain. A specific developer for ion sensitive emulsion was perfected. Sensitivity and detection threshold are increased by a factor of two or three, compared with values observed using a classical developer. Low energy particles sputtered from superficial layers of the emulsion by the impinging twenty keV ions, produce a latent image close to the surface of the silver halide grain. An oxidizing process bleaches superficial latent image and then reduces background fog. The improved signal over background ratio allows to observe lines undetectable when the plates are developed by usual process.

  1. Nonceliac gluten sensitivity: sense or sensibility?

    Science.gov (United States)

    Di Sabatino, Antonio; Corazza, Gino Roberto

    2012-02-21

    Recent studies support the existence of a new condition, nonceliac gluten sensitivity, which manifests as intestinal or extraintestinal symptoms that improve or disappear after gluten withdrawal in individuals with normal small-bowel mucosa and negative results on serum antitransglutaminase and antiendomysial antibody testing. Although the clinical value of this concept is under debate, the prevalence of nonceliac gluten sensitivity in the general population is supposed to be many times higher than that of celiac disease. The lack of an unambiguous definition of nonceliac gluten sensitivity, a major pitfall, is primarily related to the heterogeneous cause of this condition, whose symptoms are presumed to be caused by different mechanisms. If nonceliac gluten sensitivity is an etiologically heterogeneous syndrome, then management options should vary according to the predominant or concomitant underlying pathogenic pathways.

  4. Environmental assessment of packaging: Sense and sensibility

    Science.gov (United States)

    Kooijman, Jan M.

    1993-09-01

    The functions of packaging are derived from product requirements, thus for insight into the environmental effects of packaging the actual combination of product and package has to be evaluated along the production and distribution system. This extension to all related environmental aspects adds realism to the environmental analysis and provides guidance for design while preventing a too detailed investigation of parts of the production system. This approach is contrary to current environmental studies where packaging is always treated as an independent object, neglecting the more important environmental effects of the product that are influenced by packaging. The general analysis and quantification stages for this approach are described, and the currently available methods for the assessment of environmental effects are reviewed. To limit the workload involved in an environmental assessment, a step-by-step analysis and the use of feedback is recommended. First the dominant environmental effects of a particular product and its production and distribution are estimated. Then, on the basis of these preliminary results, the appropriate system boundaries are chosen and the need for further or more detailed environmental analysis is determined. For typical food and drink applications, the effect of different system boundaries on the outcome of environmental assessments and the advantage of the step-by-step analysis of the food supply system is shown. It appears that, depending on the consumer group, different advice for reduction of environmental effects has to be given. Furthermore, because of interrelated environmental effects of the food supply system, the continuing quest for more detailed and accurate analysis of the package components is not necessary for improved management of the environmental effects of packaging.

  5. Scents and sensibility: how biology perceives chemistry

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available The thermal energy storage can be defined as the temporary storage of thermal energy at high or low temperatures. Thermal energy storage is an advances technology for storing thermal energy that can mitigate environmental impacts and facilitate more efficient and clean energy systems. Seasonal thermal energy storage has a longer thermal storage period, generally three or more months. This can contribute significantly to meeting society`s need for heating and cooling. The objectives of thermal energy storage systems are to store solar heat collected in summer for space heating in winter. This concept is not new; it is been used and developed for centuries because is playing an important role in energy conservation and contribute significantly to improving the energy efficiency and reducing the gas emissions to the atmosphere.

Results showed that the IBIS model could reproduce net ecosystem CO2 exchange (NEE), sensible and latent heat fluxes reasonably, as indicated by correlation coefficients exceeding the significant level of 0.05. It was also evident that the NEE and sensible heat fluxes were characterized by diurnal and seasonal variation both in the grassland and the cropland ecosystems, while the latent heat fluxes correlated with evapotranspiration, only took on the diurnal variation during the growing season. Moreover, both sensible heat fluxes and the latent heat fluxes were larger in the cropland ecosystem than that in the degraded grassland ecosystem. This different characteristic was possibly correlated with vegetation growing situation in the two kinds of ecosystems. A close agreement between observation and simulation on NEE, sensible heat fluxes and latent heat flux was obtained both in the degraded grassland and the cropland ecosystems. In addition, the annual NEE in the model was overestimated by 23.21% at the grassland and 27.43% at the cropland, sensible heat flux with corresponding 9.90% and 11

    of latent to sensible heat flux is higher where native perennial grasses are found, particularly in wet years. Annual sums of total evaporation are likewise higher in native-dominated regions, and soil moisture is lower relative to non-natives in the deep soil. We also found that PAR albedo is lower in native grasslands compared to non-natives during significant portions of the year, and corresponding to the hotter months. In all, our findings indicate that the non-native annual grasses which now dominate California grasslands, promote conditions that support higher surface temperatures relative to native perennial grasses.

    We report 2-D maps of the O2(a1△g) emission rate (a tracer for high-altitude ozone) taken during early northern summer (Ls=102° on 30 January 2016) using CSHELL at NASA's IRTF. The entrance slit of the spectrometer was positioned N-S on Mars and stepped E-W at 0.5 arc-sec increments. Spectral extracts were taken at 0.6 arc-sec intervals along the slit. We also took data to compare the emission rates of the O2(a1△g) (1-1) band (1.28 μm) to the (0-0) band (1.27 μm) with the entrance slit centered at the sub-Earth point. A model consisting of the solar continuum with Fraunhofer lines, two-way transmission through Mars' atmosphere, and a one-way transmission through the Earth's atmosphere was used to isolate and analyze individual spectral emission lines from Mars. Boltzmann analysis of these lines yielded a rotational temperature (~165 K) that was used to determine the total emission rates for the a-X system from the measured line intensities. The line-of-sight emission rates were converted to vertical emission rates and O2(a1△g) column densities after geometric correction. The sensible O3 column implied by these data is compared with maps of total O3 in Mars standard atmosphere models.The 2-D map shows increased emission in the southern hemisphere when compared to previously reported results taken at earlier seasonal points (Ls=72° on 3 April 2010 and Ls=88° on 10 February 2014). Emission results of the O2(a1△g) (0-0) band (Local Time ~ 14:30) will be compared with MARCI results (LT ~ 15:00, Clancy et al., Icarus 266 (2016) 112-113). We searched for the (1-1) band in two adjacent wavelength ranges; (0-0) emissions were detected at these settings, but no (1-1) emissions were noticed above the noise level. An upper limit will be presented, and implications discussed.This work was partially funded by grants from NASA's Mars Fundamental Research Program (11-MFRP11-0066) and the NSF-RUI Program (AST-805540).

    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)

    Reclaimed water reused for agriculture has become one of the most effective ways to relieve water shortage and water pollution in China, especially on the North China Plain, and drip irrigation wasbelieved as the most appropriate way to use treated wastewater. Studies have verified that drip irrigation emitter clogging using reclaimed water was closely related to the formation and growing of biofilms those attached inside emitters. However, the exact effects of biofilms components’ increase on drip irrigation emitter clogging were not clear. Besides, the sensibility of emitter clogging degree to the increasing biofilms’ components as the system operated was also unknown. Based on these mentioned above, in this study, based on an on-site drip irrigation emitter clogging experiment using reclaimed water, which was conducted in the wastewater treatment plant, the emitters with seven different clogging degrees of 0, 20%, 35%, 50%, 65%, 80% and 100% were selected to reflect the growing process of biofilm, after the drip irrigation system accumulatively ran for 540 hours, and three kinds of key components (including Solid particles, Phospholipid fatty acids and Extracellular polymeric substances) of biofilms were tested, and then the sensitivity of emitter clogging degree to the increase of biofilms’ components during the whole operating was analyzed. The results showed that drip irrigation emitter clogging became more serious as biofilms’ components increased with the significant “S curve” relationship (R2> 0.92**, significant levela=0.01). Therefore, the sensitivity of emitter clogging degree to the increase of biofilms’ components showed obvious difference in different stages, with the variation trend of “sensitive - micro sensitive - extreme sensitive”. When emitter clogging degree was under 10%-15%, the biofilm growth would obviously enhance emitter clogging, while the formation of biofilms was mainly controlled by the adhesion and proliferation

    , 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.

    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.

    ABSTRACT:Objective Aimed at the service restrictions of super 13Cr-110 martensite stainless steel in standard IS15156 and the various viewpoints of its cracking condition, cracking sensibility of super 13Cr-110 martensite stainless steel at different temperatures and diverse low H2S partial pressures was studied. Methods The experiments of weight loss and three point bend-ing test were carried out in the simulated corrosion environment based on acid oilfield containing low H2S and high CO2 in West China. High temperature and pressure autoclave was used during the test. ResultsThe corrosion rate of super 13Cr-110 marten-site stainless steel diminished with the decrease of temperature. It was 0.0031 mm/a at 80℃. Nevertheless, the stress corrosion cracking sensibility increased. The corrosion rate changed a little when H2S partial pressure rose from 6 kPa to 165 kPa at 210℃. Meanwhile, the cracking sensibility of super 13Cr-110 martensite stainless steel decreased. But fissures also appeared in long-term test. Conclusion Under low H2S partial pressure, the cracking type of super 13Cr-110 martensite stainless steel showed hydrogen embrittlement sulfide-stress cracking according to the analysis on the pattern of fissure and fracture. Firstly, local passive film was damaged and then pitting corrosion occured which led to the assembling of H. Finally, hydrogen embrit-tlement happened. With the H2S partial pressure lifting from 6 kPa to 165 kPa, the cracking sensibility of 13Cr-110 caused by pitting corrosion reduced due to the restraining of pitting corrosion. Super 13Cr-110 martensite stainless steel might not be ap-plicable in the environment containing no more than 10 kPa H2S as recommended in the standard.%目的:针对IS15156标准中对超级13Cr-110马氏体不锈钢使用条件的限制,及不同研究者对其开裂条件的不同观点,研究超级13Cr-110马氏体不锈钢在不同温度、不同低H2S分压条件下的开裂敏感性。方法通过

    Full Text Available This paper will present a movement-informed perspective to social attunement in Autism Spectrum Disorders (ASD. Background: Dance movement therapy (DMT is a psychotherapeutic intervention that is used with participants with ASD in various settings. Regular clinical outcome monitoring in an outpatient setting in the Netherlands had shown positive effects on social attunement capacities in young people with ASD. However, a systematic study of the development of social attunement movement behaviors of participants with ASD throughout a DMT intervention was not yet available. Methods: A series of individual cases of DMT with young people with ASD (mean age 12.2 years. were analyzed for changes in interpersonal movement behaviors employing video-based retrospective observation. Results: The findings were summarized in an observation scale for interpersonal movement behaviors. This scale was then tested for its applicability for the monitoring of social attunement behaviors throughout therapy. Discussion: A movement-informed perspective may be helpful to inventory changes in social attunement behaviors in participants with ASD. The relevance of a movement-informed perspective for the concept of social attunement in ASD will be discussed.

    This study investigated the role of visual-perceptual input in writing Chinese characters among senior school-aged children who had handwriting difficulties (CHD). The participants were 27 CHD (9-11 years old) and 61 normally developed control. There were three writing conditions: copying, and dictations with or without visual feedback. The motor-free subtests of the Developmental Test of Visual Perception (DTVP-2) were conducted. The CHD group showed significantly slower mean speeds of character production and less legibility of produced characters than the control group in all writing conditions (psDTVP-2 was significantly correlated with the legibility among CHD (r=-0.62, p=0.001). Poor legibility seems to be related to the less-intact spatial representation of the characters in working memory, which can be rectified by viewing the characters during writing. Visual feedback regarding one's own actions in writing can also improve legibility of characters among these children.

    2014-01-01

    Robot Learning from Demonstration (RLfD) has been identified as a key element for making robots useful in daily lives. A wide range of techniques has been proposed for deriving a task model from a set of demonstrations of the task. Most previous works use learning to model the kinematics of the task, and for autonomous execution the robot then relies on a stiff position controller. While many tasks can and have been learned this way, there are tasks in which controlling the position alone is insufficient to achieve the goals of the task. These are typically tasks that involve contact or require a specific response to physical perturbations. The question of how to adjust the compliance to suit the need of the task has not yet been fully treated in Robot Learning from Demonstration. In this paper, we address this issue and present interfaces that allow a human teacher to indicate compliance variations by physically interacting with the robot during task execution. We validate our approach in two different experiments on the 7 DoF Barrett WAM and KUKA LWR robot manipulators. Furthermore, we conduct a user study to evaluate the usability of our approach from a non-roboticists perspective.

    Patient G.J., male, 7 yrs, with callosal agenesis, was found perfectly able to cross-replicate hand postures in right-to left and left-to-right directions. Bimanual coordination as well as touch localization and intermanual matching were performed without errors. He failed to name 2 out of 8 objects, palpated with the left hand. At the age of 13 patient performed like normal controls in line bisection task, was successful in intermanual replication of hand postures and intermanual matching while failed to name 8 out of 12 familiar objects palpated with the left hand. G.J.'s case does not support idea about bilateral presentation of language centers and development of compensatory ipsilateral afferents in patients with callosal agenesis. Presence of anterior and interictal commissures in G.J. did not contribute to the exchange of information between sensory areas of the right hemisphere and language centers of the left half brain. However, normal intermanual matching and replication of hand postures, as well as high level of line bisection task performance suggests, that anterior and/or intertectal commissure could contribute to the functional integration of sensory areas of the two hemispheres.

    Twenty-four children with spastic or athetoid quadriplegic cerebral palsy were paired according to severity of motor disability and age, then matched with 12 non-handicapped children of similar ages. The children were tested with a standard kinesthesiometer and two kinds of scores were recorded. Absolute Error scores reflected the children's deviation from the target and Total Movement scores reflected their over-all range of movement. There were significant differences between groups in Absolute Error scores, with the cerebral-palsied children performing worse than the controls and the spastic children worse than the athetoid children. All three groups tended to underestimate the targets and there were no significant differences in Total Movement scores.

    We present the research advances on the development of 50-200 mJ energy range diode-pumped Yb:CaF2- based multipass amplifiers operating at relatively high repetition rates. These laser amplifiers are based on diverse innovative geometries. All these innovations aim to design compact, stable and reliable amplifiers adapted to our application that consists in pumping ultrashort-pulse OPCPA (optical parametric chirped pulse amplifier) systems in the frame of the Apollon 10 PW laser project. The targeted repetition rate is in the range of 20-100 Hz with energies of few tens of mJ for the first stages up to 1 J for the final stage. An analysis of the specificities of Yb:CaF2 is done to explain the different options we chose to fulfil these specifications. The critical points and limitations of the multipass Yb:CaF2-based amplifiers are subsequently discussed. To overcome the encountered problems, different issues are investigated such as crystal optimisation, laser head geometry, thermo-optical dynamics or coherent combining techniques. Experimental results for different multipass configurations are demonstrated and discussed.

    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.

    Hexagon Obti immunological blood test and flocked swab are widely used in forensic laboratories. Nevertheless, up to now, no compatibility tests have been published between sampling with the ethylene oxide treated flocked swab and the Hexagon Obti blood detection strip. In this study, we investigated this compatibility. Our work shows that sampling with ethylene oxide treated flocked swab reduces by a factor of at least 100 the detection threshold of blood using the Hexagon Obti immunological test.

    We present the design, implementation, and deployment of a wearable computing platform for measuring and analyzing human behavior in organizational settings. We propose the use of wearable electronic badges capable of automatically measuring the amount of face-to-face interaction, conversational time, physical proximity to other people, and physical activity levels in order to capture individual and collective patterns of behavior. Our goal is to be able to understand how patterns of behavior shape individuals and organizations. By using on-body sensors in large groups of people for extended periods of time in naturalistic settings, we have been able to identify, measure, and quantify social interactions, group behavior, and organizational dynamics. We deployed this wearable computing platform in a group of 22 employees working in a real organization over a period of one month. Using these automatic measurements, we were able to predict employees' self-assessments of job satisfaction and their own perceptions of group interaction quality by combining data collected with our platform and e-mail communication data. In particular, the total amount of communication was predictive of both of these assessments, and betweenness in the social network exhibited a high negative correlation with group interaction satisfaction. We also found that physical proximity and e-mail exchange had a negative correlation of r = -0.55 (p 0.01), which has far-reaching implications for past and future research on social networks.

    The present work is dedicated to the analysis of dry heat exchanges as measured by a thermal manikin placed in still air. We believe that the understanding of some fundamental aspects governing fluid flow and heat transfer around three-dimensional bodies such as human beings deserves appropriate attention. This should be of great significance for improving physiological models concerned with thermal exposures. The potential interest of such work can be directed towards quite distinct targets such as working conditions, sports, the military, or healthcare personnel and patients. In the present study, we made use of a climate chamber and an articulated thermal manikin of the Pernille type, with 16 body parts. The most common occidental postures (standing, sitting and lying) were studied. In order to separate heat losses due to radiation and convection, the radiative heat losses of the manikin were significantly reduced by means of a shiny aluminium coating, which was carefully applied to the artificial skin. The air temperature within the test chamber was varied between 13 degrees C and 29 degrees C. The corresponding mean differences between the skin and the operative temperatures changed from 3.8 degrees C up to 15.8 degrees C. The whole-body heat transfer coefficients by radiation and convection for both standing and sitting postures are in good agreement with those in the published literature. The lying posture appears to be more efficient for losing heat by convection. This is confirmed when the heat losses of each individual part are considered. The proposed correlations for the whole body suggest that natural convection is mainly laminar.

    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.

    Full Text Available Translating pain into tangible images brings it into the public consciousness, raising the spectre of bodily suffering as virtually intrinsic to the human condition. Beginning with Descartes, who famously advanced mind-body theories in the late seventeenth century, this essay explores the effects of his influence together with shifting attitudes towards pain and its role over the long nineteenth century.

  7. Beyond fear thinking sensibly about security in an uncertain world

    CERN Document Server

    Schneier, Bruce

    2003-01-01

    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. With a well-deserved reputation for original and...

  12. Up and Out: Journalism, Social Media, and Historical Sensibility

    Directory of Open Access Journals (Sweden)

    C. W. Anderson

    2015-05-01

    Full Text Available Much of the modern theorizing about journalism and communication attained its robustness due to a powerful convergence of distinct middle-range scholarly findings that emerged primarily in the 1970s and 1980s. In the present day, when we turn our analytical gaze to the relationship between journalism and social media, we thus need to strike a delicate balance between conducting new qualitative research, re-conceptualizing and re-interrogating the classic conclusions of political communication scholarship, and linking these two aspects of research together. However, we might also wish to extend our analytical gaze “out,” interrogating the movement of journalistic technology across history, as well as “up,” looking at how journalism fits within larger structural explanations regarding the shape of political life.

  13. Techno-Anthropological Sensibilities in Health Informatics: Opportunities and challenges.

    Science.gov (United States)

    Bossen, Claus

    2015-01-01

    What kind of knowledges, skills and competences may be required by Techno-Anthropology engaging with health informatics? If we understand Techno-Anthropology to mean conducting anthropological analyses of the interwoven and mutually shaping relationship between organizing, technologies and actors in healthcare, such engagements and interventions can take many forms: Short-term consultancy work dedicated to achieving specific goals, long-term studies of broad changes in healthcare; management support within hospitals and public healthcare administration; or technology development with vendors of healthcare IT. The opportunities would seem to be manifold. Since the healthcare sector is a heterogeneous mix of interests, political agendas, professions et cetera, there is great merit in having people knowledgeable about this heterogeneity; able to facilitate meetings and processes between the various professions and organizations; and skilled in generating analyses and proposing new solutions. Also, people with insight into how action, technologies and organizing are interwoven and redistribute competences, responsibilities and risks are invaluable: Look at from afar, technologies seem to cause and determine social development, whereas detailed studies reveal that determinants and causes are both technical and social. The challenges include the one of making one's knowledge and skills legitimate and relevant to health informatics. Having a degree from arts or social sciences is not necessarily impressive for people with similar degrees in medicine, computer science, and business administration. Another challenge is to design an engagement with health informatics that will generate insights which often requires time, while also providing quick results for project sponsors or collaborators. The chapter points at three issues that seem to be central foundations for appropriate and quality-driven research and interventions of the 'quick and proper' kind: Modes of engagement; characteristics of the healthcare sector; and medical informatics and work.

    Arimilli, R.V.; Moy, C.A. [Univ. of Tennessee, Knoxville, TN (United States)

    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 ABSTRACT: The basic argument of this paper is that almost always forget that learning experiences are also experiences of subjectivity that occur within a discursive network and its regimes of truth. The object of analysis is the visual narratives produced by students of the lower grades of elementary school, from an activity developed during the preparation of the School Atlas of gestational - São Paulo. From this analysis we seek to extract visibilities. What finally present is because the educational path of cartographic initiation, drawing on their itinerary to the map need to consider in teaching activities, students' ability to live poetically reading the world. RESUMO: A argumentação básica deste trabalho é que quase sempre se esquece que as experiências pedagógicas são também experiências de subjetivação que ocorrem no interior de uma rede discursiva e de seus regimes de verdade. O objeto de análise são as narrativas visuais produzidas pelos alunos dos alunos das séries iniciais do ensino fundamental, a partir de atividades desenvolvidas com a utilização do Atlas Escolar de Sumaré-SP. A partir dessa análise procuramos extrair visibilidades. O que enfim, apresentamos é como o caminho pedagógico da iniciação cartográfica, em seu itinerário do desenho ao mapa, precisa considerar nas atividades de ensino, a capacidade dos alunos de viver poeticamente a leitura do mundo.

    2014-06-01

    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.

    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.

    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 Research of antimicrobials use and resistance in food animals have been developed in various countries, although few studies include the bacteria prevalence in respiratory tract of companion animal. The aim of this paper was to verify antimicrobial resistance profile from bronchoalveolar lavage fluid of health and sick dogs. Twenty animals were evaluated, 10 in the health group (group 1 and 10 in respiratory distress group (group 2. The bronchoalveolar lavage was performed through an endotracheal tube or guided by a rigid endoscope. Culture, identification and bacterial sensibility of the fluid were performed through agar diffusion method. The bacterial isolated were: Haemophilus aphrophilus, Staphylococcus aureus, S. epidermidis, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosas e Proteus mirabilis. Of all samples, 63% showed resistance to at least one class of antibiotics. Therefore antibiotic resistance is present in sick as well in health animals and ceftriaxone and amoxicilin associated with clavulanic acid are effective against respiratory tract bacteria.

    The human brain can generate a continuously changing postural model of our body. Somatic (proprioceptive) signals from skeletal muscles and joints contribute to the formation of the body representation. Recent neuroimaging studies of proprioceptive bodily illusions have elucidated the importance of three brain systems (motor network, specialized parietal systems, right inferior fronto-parietal network) in the formation of the human body representation. The motor network, especially the primary motor cortex, processes afferent input from skeletal muscles. Such information may contribute to the formation of kinematic/dynamic postural models of limbs, thereby enabling fast online feedback control. Distinct parietal regions appear to play specialized roles in the transformation/integration of information across different coordinate systems, which may subserve the adaptability and flexibility of the body representation. Finally, the right inferior fronto-parietal network, connected by the inferior branch of the superior longitudinal fasciculus, is consistently recruited when an individual experiences various types of bodily illusions and its possible roles relate to corporeal awareness, which is likely elicited through a series of neuronal processes of monitoring and accumulating bodily information and updating the body representation. Because this network is also recruited when identifying one's own features, the network activity could be a neuronal basis for self-consciousness.

Las plantas se regaron con diferentes aguas salinas con conductividades eléctricas de 1,3; 6; 8; 10; y 12 dS m-1, que se obtuvieron agregando NaCl:CaCl2 en relación molar 10:1 con agua fresca. Las diferencias en parámetros de crecimiento, peroxidación de lípidos, actividad superóxido dismutasa (SOD, y acumulación de prolina fueron evaluadas a fin de determinar la tolerancia o sensibilidad relativas de los cultivares. Los resultados indicaron que ambos parámetros difieren de acuerdo a la capacidad del cultivar para enfrentar el estrés oxidativo causado por la salinidad. Observamos una mayor declinación en los parámetros de crecimiento y producción de grano bajo estrés salino en 'Tajan' que en 'Bam'. El contenido de malondialdehído también fue mayor en 'Tajan'. El mejorado rendimiento de 'Bam' bajo alta salinidad se acompanó por un aumento en actividad SOD (EC 1.15.1.1 y contenido de prolina en todos los estados de crecimiento. Los resultados de los parámetros de crecimiento, peroxidación de lípidos y acumulación de prolina también se correlacionan bien apoyando que este cultivar es relativamente tolerante.

    We propose a Bayesian model for extracting sleep patterns from smartphone events. Our method is able to identify individuals’ daily sleep periods and their evolution over time, and provides an estimation of the probability of sleep and wake transitions. The model is fitted to more than 400 participants from two different datasets, and we verify the results against ground truth from dedicated armband sleep trackers. We show that the model is able to produce reliable sleep estimates with an accuracy of 0.89, both at the individual and at the collective level. Moreover the Bayesian model is able to quantify uncertainty and encode prior knowledge about sleep patterns. Compared with existing smartphone-based systems, our method requires only screen on/off events, and is therefore much less intrusive in terms of privacy and more battery-efficient. PMID:28076375

    Full Text Available In Japan, the interwoven systems of communication, transport, and information and the commercially-industrially-culturally compressed spaces of the metropoles, like Tokyo, have created super-density as new cultural form of the present. In this respect, the installation works by Seiko Mikami respond to quotidian experience with high density and lack of individual space. In her interactive installations, we are targeted by programmed multisensors and robotic devices, which invite us to engage in close encounter with the measuring and moving tools of the installation. In this human-machine-interrelationship, which is set out for multiple participants, we will also achieve a sense of each other via technology. The technological environment becomes a perceptual space, which instigates awareness and self-awareness of our own.

    Full Text Available This article presents the ethical reflexion of a recent art project, Na-no-body, presented at the Montreal gallery Espace Projet in the context of the exposition Art + Bioéthique. Na-no-body is the result of a collaborative work between the artist Stephanie Coleman and the sociologist Mathieu Noury. The aim of this project was to open an ethical dialogue on nanomedicine and its relationship with the body. To do so, the article examines specifically the notion of “personalized medicine” promoted by nanomedicine. This article proposes that, far from developing an approach reintegrating the person and the personal experience of illness at the heart of the care relationship, nanomedicine brings a simple molecular and technical response to caring. It is argued that two major themes constitute the core of this notion: 1 a molecular conception of personalization, and 2 a technical conception of personalization.

    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.

    Thermal energy storage (TES) is capable to reduce the demand of conventional energy sources for two reasons: First, they prevent the mismatch between the energy supply and the power demand when generating electricity from renewable energy sources. Second, utilization of waste heat in industrial processes by thermal energy storage reduces the final energy consumption. This review focuses mainly on material aspects of alkali nitrate salts. They include thermal properties, thermal decomposition processes as well as a new method to develop optimized salt systems.

    The author reviews Schafer's contributions to psychological testing, emphasizing his development of the test battery, his significant contributions to psychoanalytically oriented Rorschach interpretation, and his understanding of the complex interpersonal dynamics involved in psychological test interpretation. The author also discusses his use of Schafer's writing in his own teaching and academic work, noting that Schafer's contributions have not only provided innovative methods for examining test data, but have also promoted a respectful, humanistic, and individualized approach to the patient in testing and treatment. The author asserts that Schafer's later seminal contributions to psychoanalysis had their origins in his early career as a psychologist applying psychoanalytic ideas to testing.

    Full Text Available The current reassessment of sensitivity as an alternative for the production of knowledge is explained from the developments of capitalism. In cultural capitalism objects and their meanings are acquired and the market emerges as a mediator of cultural expressions, which, in as far as they are socialized, participate in a kind of mediation that implies a material or symbolic interchange. Symbolic interchange is a type of market in confrontation: either the market as a tool for the consumption of content, or as a mediation that gives to cultural expressions the necessary diversity to avoid the reduction of meaning. Capitalism has made profitable the new ways in which the senses manifest themselves, in order to insert them functionally in the operativity of the system. This entails the necessity of understanding the underlying mechanisms of the economy of culture and establishing the forms in which experience can participate in the symbolic market.

    We propose a Bayesian model for extracting sleep patterns from smartphone events. Our method is able to identify individuals' daily sleep periods and their evolution over time, and provides an estimation of the probability of sleep and wake transitions. The model is fitted to more than 400...... to quantify uncertainty and encode prior knowledge about sleep patterns. Compared with existing smartphone-based systems, our method requires only screen on/off events, and is therefore much less intrusive in terms of privacy and more battery-efficient....

  17. Voice over Internet protocol for the orthodontic practice: a sensible switch from plain old telephone service.

    Mupparapu, Muralidhar

    2008-03-01

    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.

  19. From pain to virtue: dysphoric sensations and moral sensibilities in Yap (Waqab), Federated States of Micronesia.

    Science.gov (United States)

    Throop, C Jason

    2008-06-01

    This article contributes to the development of a medical anthropology of sensation through providing a thick ethnographic description of pain's significance in the context of a particular community's - Yap (Federated States of Micronesia) - understandings of subjectivity, social action, and morality. After first proposing an attentional-synthetic model of the patterning of sensory experience, the article goes on to describe in some detail the linguistic, moral, and cultural frameworks that serve as the semiotic, existential, and practical resources providing the background against which individual sufferers tend to interpret their dysphoric sensory experiences. Central to the article is an exploration of a local illness category maath'keenil' that is implicated in two, at times competing, models of ethical subjectivity. It is argued that through configuring their subjective experiences in light of these virtues individual sufferers are at times able to transform their experiences of pain from excruciating dysphoric sensations to meaningful, morally valenced, lived experiences.

  20. Doing resilience with "half a brain:" navigating moral sensibilities 35 years after hemispherectomy.

    Hatala, Andrew R; Waldram, James B; Crossley, Margaret

    2013-03-01

    This paper investigates experiences of resilience in the context of individuals suffering from disability as a result of severe intractable seizure disorder and consequent hemispherectomy, a surgical procedure in which part or all of either the left or right cerebral hemisphere is removed. Two adults who underwent childhood hemispherectomies-one left and one right-are the focus of this study. Previous research has extensively detailed the clinical outcomes of this neurological procedure, yet the actual day-to-day experiences of individuals living post-hemispherectomy remains unexplored. Utilizing open-ended, qualitative, and narrative techniques from a phenomenology of performativity perspective, the authors question how each individual's experiences of daily living are invariably acts of resilience, involving several different strategies that are somewhat unique to each. Rather than working as an adjective or noun signifying certain environmental or individual attributes, this paper proposes that "resilience" is best conceptualized as the individualized intentional actions which disabled, distraught, or at risk individuals perform in contextually relevant and idiosyncratic ways as they navigate health and well-being within their local social and moral worlds.

    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.

  6. 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.

    2013-01-01

    With challenges in the healthcare system growing, strengthened leader and organizational resilience is often overlooked as a factor that can support staff morale and sustain performance improvement and quality. Here we examine resilience-building practices related to self-awareness, alone time, mindfulness, and a healthy perspective. A key aspect of management resilience is weighing the costs and benefits to the executive personally and to the organization if the warning signals of impairment are left untended. To that end, we propose a leader self-care protocol, which even the busy healthcare executive can find time to undertake. Ifimplemented, the protocol will allow leaders to lessen their vulnerability to burnout and help teammates whose resilience may be stretched thin. Finally, we present healthy coping skills for daily stressors and for the sudden and overwhelming situations that can negatively affect resilience.

    As the percentage of individuals over the age of 60 years continues to rise, determining the extent and functional significance of age-related declines in sensorimotor performance is of increasing importance. This review examines the specific contribution of proprioceptive feedback to sensorimotor performance in older adults. First, a global perspective of proprioceptive acuity is provided assimilating information from studies where only one of several aspects of proprioceptive function (e.g. sense of position, motion or dynamic position) was quantified, and/or a single joint or limb segment tested. Second, the consequences of proprioceptive deficits are established with particular emphasis placed on postural control. Lastly, the potential for plastic changes in the aging proprioceptive system is highlighted, including studies which relate physical activity to enhanced proprioceptive abilities in older adults. Overall, this review provides a foundation for future studies regarding the proprioceptive feedback abilities of elderly individuals. Such studies may lead to greater advances in the treatment and prevention of the sensorimotor deficits typically associated with the aging process.

    Re-examination of eight patients in whom bulbar trigeminal tractotomy had been performed 13 to 15 years previously showed that four had no complaints, and the other four had only very slight complaints about pain. In two patients a Spiller-Frazier operation had been performed after tractotomy, in two patients exairesis of the infraorbital or supraorbital nerve had been done. As bulbar trigeminal tractotomy is a major operation and the risk of recurrence is substantial, the indications for this type of operation have to remain very restricted. Theories to explain the recovery of sensation are discussed. It is possible that regeneration of transected fibres is responsible for the loss of analgesia.

    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.

    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.

    Fibromyalgia syndrome (FS) is a rheumatic syndrome affecting to 2-3% of individuals of productive age, mainly women. Neuroendocrine and genetic factors may play a significant role in development of the disease which is characterized by diffuse chronic pain and presence of tender points. Several studies have suggested an association between FS, especially pain sensitivity, and polymorphism of the catechol-O-methyltransferase (COMT) gene. The aim of the present study was to characterize the SNPs rs4680 and rs4818 of the COMT gene and assess its influence in pain sensitivity of patients with fibromyalgia screened by the Fibromyalgia Impact Questionnaire (FIQ). DNA was extracted from peripheral blood of 112 patients with fibromyalgia and 110 healthy individuals and was used as template in PCR for amplification of a 185-bp fragment of the COMT gene. The amplified fragment was sequenced for analyses of the SNPs rs4680 and rs4818. The frequency of mutant genotype AA of SNP rs6860 was 77.67% in patients with FS and 28.18% for the control group. For the SNP rs4818, the frequency of mutant genotype CC was 73.21 and 39.09% for patients with FS and controls, respectively. Moreover, the FIQ score was higher in patients with the homozygous mutant genotype for SNPs rs4680 (87.92 points) and rs4818 (86.14 points). These results suggest that SNPs rs4680 and rs4818 of the COMT gene may be associated with fibromyalgia and pain sensitivity in FS Brazilian patients.

    Цель исследования — анализ эффективности использования модифицированного (пассивное сгибание/разгибание кисти) и «стандартного» (пассивное сгибание кисти) методов кинестетических вызванных потенциалов для исследования проприоцептивной чувствительности у здоровых испытуемых и пациентов со спондилогенной шейной миелопатией. Материал и методы. В исследовании приняли участие 14 здоровых испытуемых, 4 женщины и 10 мужчин (средний возраст — 54,1±10,5 года), и 8 пациентов, 2 женщины и 6 мужчин (средний возраст — 55,8±10,9 года), со спондилогенной шейной миелопатией. При клиническом исследовании проверялось мышечно-суставное чувство. Был разработан модифицированный метод регистрации кинестетических вызванных потенциалов, который отличается от «стандартного» возможностью организации цикла из нескольких пассивных движений, причем каждое новое движение отличается от предыдущего по направлению. Результаты и заключение. Показано, что модифицированный метод регистрации кинестетических вызванных потенциалов обеспечивает повышение достоверности результатов исследования кинестетической чувствительности за счет различного характера движений. У пациентов по сравнению со здоровыми обнаружено достоверное увеличение латентных периодов ранних компонентов ответа. Модифицированный метод регистрации кинестетических вызванных потенциалов может быть использован для объективной диагностики нарушений проприоцептивной чувствительности у больных со спондилогенной шейной миелопатией.

  10. La representación, un producto de la experiencia sensible con el mundo del lenguaje // The re-presentation, a sensible exprerience product with language´s world

    Full Text Available El tema de la representación está atravesado por la perspectiva estética contemporánea. Dicha perspectiva, que tiene sus fundamentos teóricos en Kant, enseña que la representación designa la relación de la sensibilidad con la consciencia, pues el sujeto sólo percibe lo que él mismo ha creado en el momento de la mediación, a saber, cuando confronta su realidad interior con el mundo exterior. Ahora bien, la apuesta del presente texto es mostrar que en el campo del psicoanálisis freudiano: la concepción de la representación, que está influenciada por los presupuestos kantianos y nietzscheanos, comporta la transposición de la excitación nerviosa a la imagen lingüística, lo cual es propiamente un proceso del aparato psíquico, es decir, un trabajo del pensamiento inconsciente. // The subject of the representation is crossed by the contemporary aesthetic perspective. Said perspective, has its theoretical fundamentals on Kant, teaches that the representation designates the relationship between sensitivity and conscience, since the subject perceives what he/she-self has created only at mediation moment, namely, when he/she confronts his/her internal reality with the external world. Now then, the bet of the present text is to show that in the field of Freudian psychoanalysis, the conception of the representation that is influenced by the so-called Kantians and Nietzscheans, involves the transposition from nervous excitation to the linguistic image, what is exactly a process of the psychical system, which means, a work of the unconscious thought.

  12. General Relativity without paradigm of space-time covariance: sensible quantum gravity and resolution of the "problem of time"

    2014-01-01

    Covariance of space and time in General Relativity (GR) entails a number of technical and conceptual difficulties. These can be resolved by a paradigm shift from full 4-dimensional general coordinate invariance to invariance only with respect to spatial diffeomorphisms. A theory of gravity with this paradigm shift, from quantum to classical regimes, is presented; GR is contained as a special case. Appositely formulated as a master constraint, the Hamiltonian constraint now determines only dynamics; and is relieved of its dual role of generating symmetry transformations, and the consequent baggage of multi-fingered evolution with arbitrary lapse functions is absent. The Dirac algebra, with 4-dimensional diffeomorphism symmetry on-shell, is replaced by the master constraint algebra which possesses only spatial diffeomorphism gauge symmetry, both on- and off-shell. Decomposition of the spatial metric into unimodular and determinant, q, factors results in clean separation of the canonical variables. The classical...

    Full Text Available Objective: This study aimed to evaluate the sensitivity and specificity of the anti-b2-glycoprotein I antibodies for pregnancy morbidity in the antiphosoplipid syndrome (APS. Methods: 335 women were recruited and on the basis of their clinical features were subdivided into 2 groups homogenous for number and age. The first (study group contained the women whose pregnancy complications satisfied the classification criteria for APS. The second (control group was made up of women with pregnancy complications not included in the classification criteria for APS. Anti-b2-GPI, anticardiolipin antibodies (aCL and lupus anticoagulants (LA were determined in all of these women. Results: The only antiphospholipid antibodies occurring with a significant frequency (p=0,00 in the women with pregnancy criteria for APS were the IgG anti-b2-GPI and the IgG aCL present respectively in 23,92% and in 27,60% of the women. Its association was found to be significant (p=0,000. The distribution of the different levels of positivity of the IgG and IgM anti-b2 GPI in the patients of the study and control groups was not significantly different. The highest sensitivity for pregnancy complications was that of the IgG aCL and of the IgG anti-b2 GPI whose difference was not statistically significant. The comparison of the specificity of the IgG and IgM anti-b2 GPI with that of the IgG and IGM aCL was not statistically significant. Conclusions: The importance of determining the IgG anti-b2 GPI as part of routine laboratory testing of women with pregnancy complications typical of APS was confirmed. Together with IgG aCL these antibodies have proved to be the most sensitive and specific markers of pregnancy complications in APS.

    Within the Standard Model, the largest CP violation is expected in the decays of B-mesons. Because of the small branching fraction around 10{sup -6} and the difficulty in reconstructing the B{sup 0} decay vertex using π{sup 0}s, the measurement of the CP violation parameters for the channel B → π{sup 0}π{sup 0} is a highly challenging task. So far, the analysis at B-factories consisted in the measurement of the branching fraction B and the direct CP violation parameter A{sub CP}. These have been used to determine φ{sub 2}, one of the angles of the Unitarity Triangle, via the isospin analysis of the whole B → ππ system. With an expected integrated luminosity of about 50 ab{sup -1} at SuperKEKB and the capabilities of the new pixel vertex detector, the Belle II experiment will provide enough data to measure also the mixing-induced CP violation parameter S{sub CP}. For this measurement the reconstruction of either π{sup 0} → e{sup +}e{sup -}γ or converted photons from π{sup 0} → γγ is required. The obtained result would reduce the ambiguities in the φ{sub 2} measurement. Within the scope of this work the reconstruction of π{sup 0}s and converted photons is being developed in order to exploit maximally the new data set and to characterize the sensitivity of Belle II for this channel.

    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.

  1. Sensibility of GPS measurements and estimates during extreme meteorological events: the case study of mesoscale convective systems in West Africa

    Six permanent GPS stations have been deployed in West Africa within the framework of the African Monsoon Multidisciplinary Analysis (AMMA) project in order to monitor precipitable water vapor (PWV). This quantity is indeed widely employed to compute water budgets and study atmospheric processes. But in Sahel, 90% of annual rainfalls are produced by Mesoscale Convective Systems (MCSs) and PWV estimates tend to be less accurate during these extreme meteorological conditions: temperatures fall, GPS PWV estimates reach a local maximum and GPS phase residuals show strong variations that are spatially and temporally correlated. We observed that GPS phase residuals, which give insight into anomalies of the air refractivity, clearly reveal the passage of MCSs similarly as reflectivity measurements from C-band Doppler radar. The aim of this study is to evaluate the quality of the GPS PWV estimates during these events and possibly improve their estimation process. We carried out methodological and sensitivity tests on the parameterization of atmospheric delays and especially on the Gauss-Markov process which constrains the temporal variability of the GPS PWV estimates. During MCSs events, differences between GPS PWV estimates from GAMIT (2 cm.h-1/2 random walk for zenith tropospheric delays) and GIPSY (5 mm.h-1/2 random walk for zenith tropospheric delays) standard processing can for instance reach +/- 3.8 kg.m-2 . Standard GPS PWV estimates are thus subject to caution during these intense events. We therefore investigate an improved PWV estimation process which considers both zenith tropospheric delays and GPS phase residuals in order to account for the asymmetry of the air refractivity. This method leads to high-frequency PWV estimates for each GPS satellite which we compare with PWV estimates from a collocated microwave radiometer.

    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. Im Rahmen eines 2-jaehrigen Freilandexperimentes auf der Ostfriesischen Insel Norderney wurde das bodennahe Mikroklima mittels einer Gazeueberspannung auf 4 m{sup 2} grossen und mit Strandhafer (Calammophila baltica) bepflanzten Parzellen experimentell modifiziert.

  4. Canine sense and sensibility: tipping points and response latency variability as an optimism index in a canine judgement bias assessment.

    Directory of Open Access Journals (Sweden)

    Melissa J Starling

    Full Text Available Recent advances in animal welfare science used judgement bias, a type of cognitive bias, as a means to objectively measure an animal's affective state. It is postulated that animals showing heightened expectation of positive outcomes may be categorised optimistic, while those showing heightened expectations of negative outcomes may be considered pessimistic. This study pioneers the use of a portable, automated apparatus to train and test the judgement bias of dogs. Dogs were trained in a discrimination task in which they learned to touch a target after a tone associated with a lactose-free milk reward and abstain from touching the target after a tone associated with water. Their judgement bias was then probed by presenting tones between those learned in the discrimination task and measuring their latency to respond by touching the target. A Cox's Proportional Hazards model was used to analyse censored response latency data. Dog and Cue both had a highly significant effect on latency and risk of touching a target. This indicates that judgement bias both exists in dogs and differs between dogs. Test number also had a significant effect, indicating that dogs were less likely to touch the target over successive tests. Detailed examination of the response latencies revealed tipping points where average latency increased by 100% or more, giving an indication of where dogs began to treat ambiguous cues as predicting more negative outcomes than positive ones. Variability scores were calculated to provide an index of optimism using average latency and standard deviation at cues after the tipping point. The use of a mathematical approach to assessing judgement bias data in animal studies offers a more detailed interpretation than traditional statistical analyses. This study provides proof of concept for the use of an automated apparatus for measuring cognitive bias in dogs.

    Science.gov (United States)

    Carey, T A

    1994-12-01

    This paper examines the validity of the well-used proverb Spare the rod and spoil the child. To do this, the original form of the proverb from the Bible is compared with the modern form, and some significant differences are highlighted. The definition of punishment is considered, and the differences between punishment and corporal punishment are examined. Punishment is explored in some detail with attention given to the criteria that need to be satisfied in order for punishment to be effective. Discrepancies in the literature concerning these criteria are pointed out, making punishment a complex issue. The negative effects of punishment are significant with links to social problems such as teenage delinquency and violence. Reference is made to cultures where corporal punishment has been banned and the effects of this action. Given the problems associated with punishment programs, especially those being used in families, alternatives to punishment are discussed. Finally, an alternative form of the proverb to the current adaptation is offered.

  9. 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.

    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. 

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

    2012-12-01

    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.

    Full Text Available In this study, we approach the formation and the control of the child subjectivity as a manner of; implied or indirectly, among other effects; depriving it of carrying out sensitive body experiences. The relation between those two themes brings implications for the world of movements of the child, specially about its “playand-self-movement”. We call attention to an “adult-centric” view of childhood, which, many times disregards the real interests of the young ones, focusing in a preparation for the future. We consider that the valorization of the free and spontaneous playing can take the child to a meeting with the sensitive body experiences. It’s though the experience that the child is author and creator, assigning senses and meanings by creative playing. To the adults (parents and teachers fits the role of configuring opening spaces for those moments, enabling the child to know by experience.

    Background/Aims Utilization of administrative data (such as EHR data) in population-based research is resource advantageous, despite its potential limitations. Few studies have fully assessed the validity and efficiency of EHR-retrieved data. We developed ICD-9 based algorithms and operational processes to evaluate applicability of EHR-derived cancer data. Methods We retrieved data between 01/01/2002–12/30/2011 from 4 different EHR sources and developed 3 ICD9-based diagnostic algorithms (1+, 2+ and 5+). Women were classified into breast or endometrial cancers or benign breast conditions (BBC). One trained abstractor manually reviewed medical records and recorded data into a structured database. Every 10 observations were selected and reviewed. Basic descriptive statistical analyses were conducted; observations with questionable values were flagged for re-evaluation. The final dataset was considered the “gold standard” and used to validate the algorithms and to assess the duration between the diagnostic and administrative dates. Results A total of 1,056 women contributed to this study. Of these, 189 were diagnosed with breast and 40 with endometrial cancers. An additional 268 women had BBC. For breast cancer, using the first algorithm we calculated a sensitivity of 95.2% and specificity of 96.4%. Application of the second algorithm yielded a sensitivity of 94.2% and specificity of 97.6%. For the third one, our calculations indicated 89.0% sensitivity and 97.9% specificity. Our analyses based on the same algorithms yielded similar sensitivity and specificity for endometrial cancer. For BBC, we calculated a sensitivity of 82.5% and specificity of 56.7% based on the first, 73.1% sensitivity and specificity of 71.9% for the second, and 38.8% sensitivity and specificity of 90.5% for the third algorithm. The average duration between diagnostic and administrative dates for incident breast, endometrial cancers and BBC was 0.65, 0.01, and 0.31 years, respectively. Conclusions Our initial findings confirm the validity and potential utility of EHR for population-based cancer research. The algorithm of “2+ ICD-9 Coding System” yielded the most efficient process. The observed lower sensitivity and specificity for BBC potentially can be attributed to the wider pathologic spectrum of BBC. The relatively short duration between the EHR and diagnostic dates suggests unbiased interchangeability of dates.

  19. Variance Method to Determine Turbulent Fluxes of Momentum And Sensible Heat in The Stable Atmospheric Surface Layer

    Science.gov (United States)

    2005-08-01

    Evidence is presented that in the stable atmospheric surface layer turbulent fluxes of heat and momentum can be determined from the standard deviations of longitudinal wind velocity and temperature, σ u and σ T respectively, measured at a single level. An attractive aspect of this method is that it yields fluxes from measurements that can be obtained with two-dimensional sonic anemometers. These instruments are increasingly being used at official weather stations, where they replace the standard cup anemometer wind vane system. With methods such as the one described in this note, a widespread, good quality, flux network can be established, which would greatly benefit the modelling community. It is shown that a ‘variance’ dimensionless height (ζ σ) defined from σ u and σ T is highly related to the ‘conventional’ dimensionless stability parameter ζ=z/L, where z is height and L is the Obukhov length. Empirical functions for ζ σ are proposed that allow direct calculation of heat and momentum fluxes from σ u and σ T. The method performs fairly well also during a night of intermittent turbulence.

    Bandler and Grinder's hypothesis that eye-movements reflect sensory processing was examined. 28 volunteers first memorized and then recalled visual, auditory, and kinesthetic stimuli. Changes in eye-positions during recall were videotaped and categorized by two raters into positions hypothesized by Bandler and Grinder's model to represent visual, auditory, and kinesthetic recall. Planned contrast analyses suggested that visual stimulus items, when recalled, elicited significantly more upward eye-positions and stares than auditory and kinesthetic items. Auditory and kinesthetic items, however, did not elicit more changes in eye-position hypothesized by the model to represent auditory and kinesthetic recall, respectively.

  1. Agraphesthesia. A disorder of directional cutaneous kinesthesia or a disorientation in cutaneous space.

    1982-03-01

    Tests for graphesthesia and for directional cutaneous kinesthesia (DCK) were performed on a large series of neurological patients and normal subjects, in addition to the standard tests for discriminative sensation. Defects in graphesthesia and DCK were found with lesions at all levels of the nervous system. Graphesthesia was more often and more severely affected than DCK. These functions when impaired were always associated with other sensory defects (directional joint kinesthesia, two-point discrimination, etc.) in different combinations. It appears DCK is probably the basis for graphesthesia. Recent experimental studies have provided an anatomic and physiologic basis for DCK and for graphesthesia. These studies have also discredited wide-held beliefs on the transmission of discriminative sensation through the spinal cord. In this light, the history of ideas about sensation and its mediation is reviewed, and it is concluded that DCK alone deserves to be called a "posterior column function". Graphesthesia and DCK are discussed as kinesthetic functions implying orientation in cutaneous sensory space. These are compared to stereognosis and braille reading, which are complex derived functions depending also on motion, but directed towards recognition in external haptic space. Graphesthesia and DCK should both be considered as distinct forms of somatic sensibility which are valuable adjuncts to the clinical sensory examination.

  3. Overweight and Obese Adolescent Girls: The Importance of Promoting Sensible Eating and Activity Behaviors from the Start of the Adolescent Period

    Directory of Open Access Journals (Sweden)

    Alwyn S. Todd

    2015-02-01

    Full Text Available The adolescent period is associated with changes in eating and activity behaviors in girls. Less reliance on parental provision and choice of food, coupled with a decrease in participation in physical activity and sport, can create an energy imbalance, predisposing to weight gain. Physiological alterations to body composition, reduction in insulin sensitivity, and psychological adjustments may further amplify the risk of becoming overweight and maintaining an unhealthy level of body fat into childbearing years. During pregnancy excess body fat is a risk factor for poor pregnancy outcomes and may predispose an infant to a lifelong heightened risk of being overweight and developing chronic disease. Interventions aimed at preventing the accumulation of body fat in adolescent girls and young women may have far reaching impact and be critically important in reducing intergenerational weight gain. Lifestyle interventions in adolescence have the potential to modify adult obesity risk by switching at-risk individuals from a high to lower obesity risk trajectory. This paper discusses multiple approaches to assist at-risk individuals reduce obesity risk. A key focus is placed on engagement in food preparation and choice, and opportunities for physical activity and sport. Support, education, and opportunity at home and at school, are often associated with the success of lifestyle interventions, and may enable adolescents to make positive choices, and engage in health promoting behaviors during adolescence and childbearing years.

    Climate, vegetation cover, and management create fine-scaleheterogeneity in unirrigated agricultural regions, with important but notwell-quantified consequences for spatial and temporal variations insurface CO2, water, and heat fluxes. We measured eddy covariance fluxesin seven agricultural fields--comprising winter wheat, pasture, andsorghum--in the U.S. Southern Great Plains (SGP) during the 2001-2003growing seasons. Land-cover was the dominant source of variation insurface fluxes, with 50-100 percent differences between fields planted inwinter-spring versus fields planted in summer. Interannual variation wasdriven mainly by precipitation, which varied more than two-fold betweenyears. Peak aboveground biomass and growing-season net ecosystem exchange(NEE) of CO2 increased in rough proportion to precipitation. Based on apartitioning of gross fluxes with a regression model, ecosystemrespiration increased linearly with gross primary production, but with anoffset that increased near the time of seed production. Because theregression model was designed for well-watered periods, it successfullyretrieved NEE and ecosystem parameters during the peak growing season,and identified periods of moisture limitation during the summer. Insummary, the effects of crop type, land management, and water limitationon carbon, water, and energy fluxes were large. Capturing the controllingfactors in landscape scale models will be necessary to estimate theecological feedbacks to climate and other environmental impactsassociated with changing human needs for agricultural production of food,fiber, and energy.

    A novel approach is developed to evaluate quantitatively the influence of operational inefficiency in biomass production on the life-cycle performance of hydrogen from biomass gasification. Vine-growers and process simulation are used as key sources of inventory data. The life cycle assessment of biohydrogen according to current agricultural practices for biomass production is performed, as well as that of target biohydrogen according to agricultural practices optimised through data envelopment analysis. Only 20% of the vineyards assessed operate efficiently, and the benchmarked reduction percentages of operational inputs range from 45% to 73% in the average vineyard. The fulfilment of operational benchmarks avoiding irregular agricultural practices is concluded to improve significantly the environmental profile of biohydrogen (e.g., impact reductions above 40% for eco-toxicity and global warming). Finally, it is shown that this type of bioenergy system can be an excellent replacement for conventional hydrogen in terms of global warming and non-renewable energy demand.

    Full Text Available George es un tenista que en este momento se encuentra a instantes de realizar un smash para rematar un partido. Anna, por su parte, está en la cacería de un inoportuno insecto volador utilizando una raqueta eléctrica. Si detuviésemos el tiempo en el instante en que George y Anna alzan sus brazos, sin acceder al contexto en el que la acción tiene lugar, ¿seríamos capaces de detectar la intención que subyace a cada movimiento? Estudios recientes sugieren que esto es posible a partir del análisis de la velocidad y trayectoria de acciones que, a primera vista, parecen idénticas.

    Full Text Available In this paper we present one year of meteorological and flux measurements obtained near Ny-Ålesund, Spitsbergen. Fluxes are derived by the eddy covariance method and by a hydrodynamic model approach (HMA as well. Both methods are compared and analyzed with respect to season and mean wind direction. Concerning the wind field we find a clear distinction between 3 prevailing regimes (which have influence on the flux behavior mainly caused by the topography at the measurement site. Concerning the fluxes we find a good agreement between the HMA and the eddy covariance method in cases of turbulent mixing in summer but deviations at stable conditions, when the HMA almost always shows negative fluxes. Part of the deviation is based on a dependence of HMA fluxes on friction velocity and the influence of the molecular boundary layer. Moreover, the flagging system of the eddy covariance software package TK3 is briefly revised. A new quality criterion for the use of fluxes obtained by the eddy covariance method, which is based on integral turbulence characteristics, is proposed.

  18. Considerations for the sensible use of rodent models of inflammatory disease in predicting efficacy of new biological therapeutics in the clinic.

    Successful therapeutics for treating autoimmune and inflammatory diseases must be able to significantly dampen, and ideally reverse, the complex processes involved in the manifestation of inflammatory pathology in intact tissues and organs. Studies on human cells and tissues - both normal and diseased - are obviously critical for moving forward with a particular therapeutic strategy, but these types of studies are oftentimes limited in their complexity and usually fail to fully replicate the biology of the intact inflammatory environment and disease process. It is for this reason that development of a new drug generally relies on data generated from in vivo animal models that have been created to mimic aspects of the complex disease process in whole organs and whole animals. Although the intact animal model of disease provides the opportunity for key elements involved in inflammatory processes to be investigated in natural surroundings, the primary trigger for inflammatory activation in animal models is, by necessity, artificial and, of course, differs from the natural pathogenesis driving disease in humans. Despite the artificial way of inducing inflammatory responses, animal models of disease have proven invaluable for providing insight into the potential efficacy of new drugs, particularly when careful consideration has been given to ensure that the model system under study resembles the inflammatory pathway expected in human disease. The most common artificial approaches for stimulating inflammatory diseases in mice are quite varied, and range from overexpression or targeted deletion of genes in transgenic or knockout animals, immunization of animals with putative autoantigens, all the way to synthetic, chemical challenges. None of these artificial systems or triggers is wholly perfect at mimicking the complexity of human autoimmune and inflammatory diseases, but animal disease model data is an important, and very necessary, step in the path of drug development. This review will focus on the critical aspects of disease modeling in animals that should be considered when embarking on drug discovery programs, with particular attention on three of the major inflammatory diseases - rheumatoid arthritis, multiple sclerosis and asthma. We will discuss the use of rodent models in predicting the outcomes of currently approved medicines with a focus on biological therapeutics, and will highlight ongoing clinical trials where there appears to be strong correlation between animal models and the initial indication of clinical efficacy.

    Full Text Available Se propone un algoritmo de marca de agua para video digital, en donde la inserción y detección de la marca de agua se realiza durante el proceso de codificación MPEG-2. La señal de marca de agua esta incrustada en los coeficientes de DCT en el canal azul de los cuadros I y P del video MPEG. La energía de la marca de agua se calcula usando la sensibilidad visual de los cuadros (I y P y la magnitud de los vectores de movimiento en los cuadros de P. Los resultados de simulación computacional muestran la imperceptibilidad de marca de agua, obteniendo un PSNR mayor a 45dB, conservando la robustez de la misma cuando es sometida a diversas distorsiones, tales como contaminación por ruido, recorte, y eliminación de cuadros, entre otros. El algoritmo propuesto tiene una influencia mínima en la velocidad del proceso de codificación MPEG.A video watermarking algorithm, in which watermark embedding and detection process are carried out during the MPEG-2 coding process is proposed. The watermark signal is embedded in the DCT coefficients of blue channel of I-frames and P-frames. The embedding energy is computed adaptively using perceptual information of the I-frames and the P-frames, and motion vectors information in the P-frame. Computer simulation results show the watermark imperceptibility, obtaining a PSNR greater than 45 dB and maintaining its robustness to common signal distortions such as contamination by noise, cropping, frame dropping, frame swapping and frame averaging, among others. The proposed algorithm has very little influence on the MPEG decoding speed.

  2. Regulación por proteasas del canal de sodio sensible al amiloride (ENaC Amiloride sensitive sodium channels (ENaC and their regulation by proteases

    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.ENaC is a channel that mediates entry of Na+ from the luminal fluid into the cells in many reabsorbing epithelia and it is also expressed in human placenta. ENaC is crucial in the control of electrolyte and extracellular volume homeostasis. ENaC is regulated by several hormones, including aldosterone and blocked by amiloride and its analogs. ENaC channels are composed by three homologous subunits, α, β and γ that form the pore where Na ions are transported. Two factors regulate the activity of ENaC channels: 1 the number of channels inserted in the membrane and 2 the open probability of the channels or time that the channel is open. The number of channels is the result of a balance between the synthesis and degradation of ENaC channels. The open probability depends on the proteolysis of specific segments in the α and γ subunits of ENaC by multiple proteases inside of the cell or in the extracellular space. Among the most studied proteases are furin, prostasin, elastase, plasmin and trypsin. There are endogenous substances that block the activity of these proteases such as aprotinin, bikunin and nexin-1 and the expression of both, proteases and their inhibitors are controlled by the rate of Na+ movement, aldosterone and TFG-β levels. In this work we present some examples of this regulation and the potential role that this process may play under normal and pathological conditions such as cystic fibrosis, kidney diseases and hypertension.

    Objective To observe the effects of PSD95 gene specific siRNAs on neuropathic pain relief,neuron viability,and postsynaptic calcium/calmodulin-dependent protein kinase Ⅱα (CaMKⅡα) phosphorylation in vitro and in vivo.Methods Gene-specific siRNAs of rat PSD95 were synthesized chemically for transfection.Adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups:naive group (n=6),sham group (n=6),and sciatic nerve chronic constriction injury (CCI) group (n=24).The CCI group was further divided into 4 groups (n=6 in each group),which were pretreated with normal saline,transfection vehicle,negative control siRNAs,and PSD95 gene specific siRNAs respectively.All the subgroups received corresponding agents intrathecally for 3 days,started one day before the CCI of sciatic nerve.Both mechanical allodynia and thermal hyperalgesia were measured on post-operative day 3 and 7.PSD95 gene silenced NG108-15 cells were further stimulated by glutamate,with the cell viability and the expression/phosphorylation of CaMKⅡα measured by MTT cell proliferation assay andWestern blot,respectively.Results The siRNAs decreased PSD95 mRNA level significantly both in vivo and in vitro.Neuropathic pain rats pretreated with PSD95 gene specific siRNAs exhibited significant elevation in the mechanical withdrawal threshold and paw withdrawal thermal latency,without affecting the baseline nociception.PSD95 gene silencing enhanced neuronal tolerance against the glutamate excitotoxicity,meanwhile the phosphorylation of CaMKⅡαThr286 was attenuated.Conclusion Pre-emptive administration of PSD95 gene specific siRNAs may attenuate the central sensitization CaMKⅡα-related signaling cascades,leading to the relief of neuropathic pain.

As cultivares foram: 'FT-Guaira', 'Embrapa-48', 'Ocepar-14', 'BR-16', 'Embrapa-4', 'Ocepar-13', 'BR-36', 'FT10-Princesa', 'FT-2000', 'FTAbyara', 'BR-37' e 'RS7- Jacuí'. O diclosulam foi utilizado nas doses de 35 g/ha (normal e 70 g/ha (dobrada; e o flumetsulam nas doses de 120 g/ha (normal e 240 g/ha (dobrada; também foi utilizada a mistura de diclosulam + flumetsulam (20 + 100 g/ha; e imazaquin à 150 g/ha. Nas doses normais utilizadas dos dois herbicidas não foi possível distinguir nenhuma cultivar suscetível. Em dose dobrada do diclosulam os rendimentos das cultivares 'FT-Guaira', 'Embrapa 4' e 'BR-37 ' foram reduzidos em 20,9 %, 11,8 % e 11,0 % respectivamente, em relação à testemunha. O flumetsulam à 240 g/ha e sua mistura com diclosulam também reduziu o rendimento destas cultivares, mais o da 'Ocepar-14'. A maioria das cultivares teve o estande reduzido, nas doses dobradas dos dois herbicidas, mas também sem significância. Somente o estande da cultivar 'Embrapa-48' não foi afetado, ao contrário da 'RS-7 Jacuí'. A altura de plantas foi menor em relação à testemunha no tratamento com flumetsulam à 240 g/ha. Na maioria das cultivares o peso da biomassa seca de nódulos foi menor nas doses dobradas, e em algumas também o peso por unidade de nódulos. A biomassa seca da parte aérea e da raiz não foram reduzidas.The objective of the present paper was to check the behaviour of 12 different soybean cultivars in relation to the tolerance to the herbicides flumetsulam and diclosulam applied on a soil classified as Latossolo Roxo distrófico (80,87% of clay, pH of 5,4 and 3,07 of organic matter in Londrina - PR.

    Full Text Available Background: This study determines whether -week high-fat diet (HFD consumption alters insulin sensitivity, kidney function, and blood pressure (BP in female rats when compared with standard rodent diet (ND intake in gender- and age-matched rats. Methods: The present study investigates, in female Wistar HanUnib rats, the effect of long-term high-fat fed group (HFD compared with standard chow on BP by an indirect tail-cuff method using an electrosphygmomanometer, insulin and glucose function, and kidney function by creatinine and lithium clearances. Results: The current study shows glucose tolerance impairment, as demonstrated by increased fasting blood glucose (ND: ±2.8 vs. HFD: 87±3.8 mg/dL associated with reduced insulin secretion (ND: 0.58±0.07 vs. HFD: 0.40±0.03 ng/mL in 8-week female HFD-treated rats. The incremental area under the curve (AUC, ND: 1,4558.0±536.0 vs. HFD: 1,6507.8±661.9, homeostasis model assessment of insulin resistance (HOMA-IR index, and the first-order rate constant for the disappearance of glucose (Kitt were significantly enhanced in 8-week HFD-treated rats compared with age-matched ND group (respectively, P=0.03, P=0.002, and P<0.0001. The current study also shows a significantly higher systolic BP measured in 5 and 8 weeks posttreatment in HFD (5-week HFD-treated: 155.25±10.54 mmHg and 8-week HFD-treated: 165±5.8 mmHg (P=0.0001, when compared to BP values in 5-week ND, 137±4.24 mmHg and 8-week ND, 131.75±5.8 mmHg age-matched group. Otherwise, the glomerular filtration rate and renal sodium handling evaluated by FENa, FEPNa and FEPPNa, were unchanged in both groups. Conclusion: We may conclude that 8-week female HFD-fed rats compared with ND group stimulate harmful effects, such as BP rise and peripheral glucose intolerance. The increased BP occurs through insulin resistance and supposedly decreased vasodilatation response without any change on renal function.

    Gessinn, F.

    1993-12-01

    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 {mu}m thick silica layers have been fabricated for our experiments. The radiation response of our devices in the high-field mode satisfactorily fits a D{sub ox}{sup 2} power law. The maximum sensitivity achieved (9,2 V/Gy for 2{mu}m devices) is close to the ideal value obtained when considering only an unitary carrier-trapping level, and allows to measure about 10{sup -2} Gy radiation doses. Read-time stability has been evaluated under bias-temperature stress conditions: experiments underscore slow fading, corresponding to 10{sup -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.

  19. Modulation of jaw muscle spindle afferent activity following intramuscular injections with hypertonic saline.

    Ro, J Y; Capra, N F

    2001-05-01

    Transient noxious chemical stimulation of small diameter muscle afferents modulates jaw movement-related responses of caudal brainstem neurons. While it is likely that the effect is mediated from the spindle afferents in the mesencephalic nucleus (Vmes) via the caudally projecting Probst's tract, the mechanisms of pain induced modulations of jaw muscle spindle afferents is not known. In the present study, we tested the hypothesis that jaw muscle nociceptors gain access to muscle spindle afferents in the same muscle via central mechanisms and alter their sensitivity. Thirty-five neurons recorded from the Vmes were characterized as muscle spindle afferents based on their responses to passive jaw movements, muscle palpation, and electrical stimulation of the masseter nerve. Each cell was tested by injecting a small volume (250 microl) of either 5% hypertonic and/or isotonic saline into the receptor-bearing muscle. Twenty-nine units were tested with 5% hypertonic saline, of which 79% (23/29) showed significant modulation of mean firing rates (MFRs) during one or more phases of ramp-and-hold movements. Among the muscle spindle primary-like units (n = 12), MFRs of 4 units were facilitated, five reduced, two showed mixed responses and one unchanged. In secondary-like units (n = 17), MFRs of 9 were facilitated, three reduced and five unchanged. Thirteen units were tested with isotonic saline, of which 77% showed no significant changes of MFRs. Further analysis revealed that the hypertonic saline not only affected the overall output of muscle spindle afferents, but also increased the variability of firing and altered the relationship between afferent signal and muscle length. These results demonstrated that activation of muscle nociceptors significantly affects proprioceptive properties of jaw muscle spindles via central neural mechanisms. The changes can have deleterious effects on oral motor function as well as kinesthetic sensibility.

    Neurologic complications after roller coaster rides are uncommon but potentially catastrophic. Physicians should have a high index of suspicion and prompt appropriate investigation. A 22-year-old healthy African American man presented with a 2-day history of constant occipital headache associated with vertigo, nausea, vomiting, and ambulatory dysfunction. Physical examination showed gait ataxia, slight dysmetria, and vertical nystagmus. Magnetic resonance imaging (MRI) of the brain showed early subacute ischemic infarct in the right cerebellum in the distribution of the right posterior inferior cerebellar artery. Magnetic resonance angiography of the neck showed focal dissection of the right vertebral artery at C1 through C2 level. On subsequent questioning, the patient recollected riding a roller coaster 2 weeks before the onset of symptoms. Anticoagulation with heparin was started, and the patient was bridged to oral warfarin. After a 5-day uneventful hospital course, symptoms improved and patient was discharged on oral anticoagulation. Cervicocephalic arterial dissections after roller coaster rides are rarely described in literature. The acceleration and abrupt changes of direction might lead to indirect trauma that is applied to mobile portions of the cervicocephalic arteries leading to intimal tears. Magnetic resonance angiography combined with axial T1-weighted cervical MRI is preferred because it is a high-sensitive, noninvasive test. The rationale for the use of anticoagulants or antiplatelets in patients with cervicocephalic arterial dissection is to prevent early recurrence and infarction. However, a meta-analysis failed to show significant difference in the rates of disability or death between both groups. Therefore, the decision for medical treatment should be made in a case-by-case basis.

    Full Text Available The course of cervicocephalic fibromuscular dysplasia is mainly asymptomatic. It is often found as an incidental finding on autopsy or angiography mostly in women and is commonly located in extracranial region of carotid artery. In the present article, we reported a 21 year-old man who has been initially accepted to our intensive care with a tentative diagnosis of cerebrovascular infarct after having symptoms of loss of consciousness and right hemiparesis. He later received a certain diagnosis of fibromuscular dysplasia after neuroimaging findings. This disorder should be considered in differential diagnosis of young stroke patients.

    Volumetric adsorption experiment is the primary method to determine the adsorption capability and gas content of coal reservoirs. Reference cylinder volume V1, free volume V2 in sample cylinder and pressure gauge precision were identified as the key factors influencing adsorption experiment. To understand how the parameters impact isotherm adsorption experiment results and improve the precision of the experiment, in this paper, stability analysis and accuracy analysis were performed for adsorption experiment according to Boyle's law. Based on the established models, the adsorption experiments are simulated by Matlab software. The result shows that the stability and the accuracy of experiment are controlled by V1, V2, pressure gauge precision and reference cylinder volume. The higher pressure gauge precision, the more stable and precise adsorption experiment is. When the pressure gauge precision is fixed, only V1 and V2 are smaller and satisfy certain conditions which have been simulated can the experiment achieve good stability and precision. Comparative isothermal adsorption experiment was conducted on medium rank coal from Hancheng area in the eastern Ordos basin by using the results obtained from optimization. Result indicates that the quality of adsorption results is improved, the maximum adsorption difference is 1.45 cm3/g, far less than 5.27 cm3/g from the experiment not optimized by models.%容量法等温吸附实验是测定煤储层吸附性和含气性的常用手段。实验装置中的参考缸体积V1、装有样品时的自由空间体积V2和压力表对等温吸附实验有着直接的影响,但是这三者对实验影响的程度目前还没有系统的认识。为了理清实验过程中各参数的影响和提高等温吸附实验的测试精度,基于波义尔定律建立了煤储层容量法等温吸附实验稳定性和精确性分析的数学模型,利用Matlab软件对吸附实验过程进行了数值模拟。研究表明,吸附实验的稳定性和准确性受压力表、参考缸的体积V1和样品缸装有样品时的自由空间体积V2的控制,压力表测量精度越高,等温吸附实验的稳定性和精确性就越好;压力表精度一定时,V1和V2的体积较小且匹配组合满足一定的条件,吸附实验才能达到较好的稳定性和精确性。利用优化方法得到的结果对鄂尔多斯盆地东缘韩城地区中煤阶煤储层开展等温吸附对比实验,结果表明,经过优化组合的吸附实验测试结果稳定和精度都有所提高,吸附量的最大差值为1.45 cm3/g,远低于未经过优化的实验所测吸附量的差值5.27 cm3/g。

    The intense flow of fossil fuels in the inland waters of Patos Lagoon (LP) - Rio Grande do Sul, justifies the importance of preventive actions to claims by oil and derivatives within the lagoon. The mapping and classification of coastline environmental sensitivity for oil spills (Cartas SAO) is fundamental tool for this type of action. Therefore, since 2001, the Laboratory of Geological Oceanography (LOG) of Federal University of Rio Grande (FURG) has developed the mapping SAO for the LP. In this work, through review of raw data from the database of LOG, and taking into account the methodology proposed by the Ministry of Environment (MMA, 2004), gave up a strategic projection of standardized environmental sensitivity of the oil spill to Patos Lagoon. This new account also enable a better understanding of the lagoon ecosystem, enables comparisons between its different areas, facilitating the planning and decision-making, allowing the management for faster action-in response. Like, highlights the regions of the estuary of the LP, the delta of the Camaqua River and Casamento Lagoon as the areas of greater sensitivity to environmental spillage of oil from Patos Lagoon.

    The absorbed dose by the bladder, the rectum and the gland thyroid was measured during a treatment applied for prostate cancer by means of a Cobalt 60 unit. The dose was measured using thermoluminescent dosimeters of the type TLD 100, with the values of the absorbed the values of the effective dose were calculated and was determined the probability of the development of a secondary cancer. Because these measurements cannot be made -in vivo- a phantom or mannequin was built with water that represents the hip and part of the torso of the human body and to represent the neck was used polyethylene. The study was carried out in the Instituto Zacatecano del Tumor that has a -cobalt bomb- which is used to treat oncology patients, during the phantom irradiation a dose of 200 c Gy was applied of this dose the bladder received 96.7%, the rectum 100.8% and the gland thyroid 0.3%. The dose received by the rectum and the bladder is due to the therapeutic beam while the dose received by the thyroid is due to the dispersed radiation by the phantom. The probability that in these organs a new neoplasm is developed is of 0.033% for the bladder, 0.157% for the rectum and 7.8 x 10{sup -5}% for the thyroid case. (Author)

    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 X{sup 2} 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)

    In the traditional self -organizing feature mapping algorithm network system algorithm, the performance of the algorithm was much sensitive to the initial value of the codebook. An improved image coding method with low distortion and low sensitive gauge property was proposed based on the self-organizing feature mapping network. The distortion de-gree was decreased effectively. The probability of the coding vector which had been used as the response vector and was going to be taken as the response vector again was decreased finally, and the contradiction of the performance and the quantity of the coding book was balanced. Result shows that the performance of the improvement is obvious, and the peak signal-Noise ratio is improves with 3.75 dB, the performance of image restoration is true and effective, and it can be applied in the image vector quantization and image coding in practice.%传统的自组织神经网络系统进行图像量化处理和编码中,算法对于码书初始值选择具有较强的敏感性,从而导致该量化编码算法对训练序列具有较大的依赖性。为此提出基于自组织神经映射网络系统的低失真敏感测量度图像编码图像量化编码方案,主要是针对初始码书的较强敏感性而改进的,以便改进码书的性能和训练效率。改进的方法中通过设置一个响应的频率计数器。由失真的敏感参数对失真测度进行调整,有效降低失真程度,从而减少了已被用作响应码氏的码氏再度成为响应码氏的概率,实现了对码书性能和数量之间的矛盾进行有效地平衡折中。训练效果和仿真结果表明,方法改进效果明显,其峰值信噪比相比提高了3.75 dB,图像还原效果真实有效,能有效适用于对图像向量量化和编码。

    Full Text Available Este artigo problematiza o uso da literatura como recurso estético durante o processo de ensino da administração, com base em uma análise multidisciplinar dos trabalhos acadêmicos publicados, com a finalidade de: refletir sobre literatura e o papel da ficção no ensino, articulando a literatura com a existência humana; abordar a pesquisa em organizações e o uso de gêneros e estilos literários na produção do conhecimento; e discutir sobre os usos dos textos literários em ensino, pelo relato e discussão de práticas que utilizam a literatura. Tem especial destaque a dimensão estratégica da atividade de ensino que usa a literatura como recurso estético. A conclusão é de que o texto literário é um poderoso recurso de aprendizagem, pois tem como matéria-prima a palavra, o discurso, que é a essência da administração. E, também, que a integração entre administração e literatura pode ser uma estratégia fecunda, favorecendo criatividade e descoberta, pois possibilita o desenvolvimento de capacitações para sentir e conhecer.The goal of this article is to challenge the use of literature as an aesthetic resource in management teaching-learning. The research is based on a multidisciplinary literature review in order to: think about fiction and its role in teaching, articulating fiction with human existence; explore organizational research and the use of literary genres and styles in knowledge production, and discuss about the use of literary texts in teaching through the presentation and discussion of practices using and capitalizing on fiction. Special attention is given to the strategic dimension of teaching activity that uses fiction as an aesthetic resource. The research's conclusion suggests that literary text is a powerful learning resource because it has as primary source accounts and discourse, these being the essence of management. Another conclusion is that the relationship between management and literature translates into a rich strategy, encouraging creativity and discovery as it allows the development of capabilities to feel and to know.

    马克思关于“感性世界”的实践论诠释,对于我们理解马克思哲学的本体论内涵具有十分重要、十分独特的意义.而在马克思之前,康德和费希特分别对感性世界作出了各具特色的理论阐释.费希特从纯粹自我的纯粹活动出发,把感性世界理解为由“自我”设定的“非我”的世界,由此确认人的存在的二重性,并认为人的存在必然面遇世界的二重化,即作为经验世界的感性世界和作为道德秩序而存在的“超感性世界”.但他认为,人作为理性的能动的“自我”是可以把这两个世界结合起来的,即通过自我的实践活动,可以把作为超感性世界的道德秩序建构到感性世界中.马克思则从人的能动的感性活动出发,以人的存在和人的活动的对象性为依据,对费希特哲学作出了深刻的批判和改造,把感性世界理解为以人的感性活动为基础的世界.

    Microsurgical techniques open the way for much creativity and originality for cervicofacial reconstruction and tumoral repair. Between 1976 and 1994, we performed 481 free transplants for cervico-facial reconstruction. A recently developed strategy has been the use of multiple free transplants, either simultaneously or successively. Between 1990 and 1994, we operated and reconstructed 9 patients using multiple free cervico-cephalic transplants after multitissular and agressive exeresis for tumoral or traumatic lesions. In 3 cases, the transplants were made simultaneously and in the 6 others successively. Three patients received 3 free transplants and 6 patients had 2. In 8 cases, each of the transplants was micro-anastomosed on different vessels. In one case, the two transplants were anastomosed in series, the most distal portion being connected to the most proximal portion (in comparison with the cervical vessels). One death occurred at 6 weeks due to infectious complications. The final result for the 8 other patients was good both morphologically and functionally. Indications for multiple free transplants include: complex tissue loss, multiple and massive tissue loss of the cervicocephalic region. This situation occurs particularly in case of voluminous tumours invading several structures, in multiple tumours and in firearm wounds. These series of patients allowed a definition of recommended techniques in case of difficulties in these very elaborate surgical procedures and confirmed that if the strategy is correctly planned, it is possible to greatly improve the quality of survival in these patients in terms of aesthetics, morphology and function.

    Although evidence points to a role for kinesthetic empathy (i.e. spontaneous interpersonal movement imitation and synchronisation) in social interaction, its relationship with emotional and cognitive aspects of empathy is unknown. We compared empathy in Tango and Capoeira experts, which crucially depend on ongoing, mutual interpersonal synchronisation, with empathy in practitioners of Salsa and Breakdance, respectively, which demand less interpersonal synchronisation but are comparable concerning movements and setting. Kinesthetic empathy was increased in the Tango and Capoeira groups. Although no group differences in other aspects of empathy were detected, kinesthetic empathy correlated with emotional and cognitive empathy. Taken together, trait kinesthetic empathy varies in the general population, and appears increased in synchronisation experts.

  13. Physics Learning Strategies with Multi-touch Technology

    Advancements in technology have opened doorways to build new teaching and learning methods. Through conjunctive use of these technologies and methods, a classroom can be enriched to stimulate and improve student learning. The purpose of our research is to ascertain whether or not multi-touch technology enhances students' abilities to better comprehend and retain the knowledge taught in physics. At their basis, students learn via visual, aural, reading/writing, and kinesthetic styles. Labs provide for all but the aural style, while lectures lack kinesthetic learning. Pedagogical research indicates that kinesthetic learning is a fundamental, powerful, and ubiquitous learning style. By using multi-touch technology in lecture, not only can we accommodate kinesthetic learners, but we can also enrich the experiences of visual learners. Ushering to this wider array of students will hopefully lead to an increase in meaningful learning.

  14. Tactile feedback as a sensory subtraction technique in haptics for needle insertion

    Prattichizzo, D; Rosati, G

    2011-01-01

    A sensory substitution technique is presented in which the kinesthetic and tactile feedback are substituted by tactile feedback only provided by two wearable devices able to apply forces to the index finger and thumb holding a handle during a needle insertion task. The force pattern fed back to the user while using the tactile device is similar, in terms of intensity and area of application, to that perceived while interacting with a haptic device providing both tactile and kinesthetic feedback and it can be thought as a subtraction between the complete haptic and kinesthetic feedback. For this reason we refer to this approach as sensory subtraction instead of sensory substitution. A needle insertion scenario is considered. The haptic device is connected to a virtual environment simulating a needle insertion task. Experiments show that the perception of inserting a needle using the tactile feedback only is nearly indistinguishable from the one felt by the user using both tactile and kinesthetic feedback. As m...

  17. Eye-hand coordination during dynamic visuomotor rotations.

    Directory of Open Access Journals (Sweden)

    Lorenzo Masia

    Full Text Available BACKGROUND: for many technology-driven visuomotor tasks such as tele-surgery, human operators face situations in which the frames of reference for vision and action are misaligned and need to be compensated in order to perform the tasks with the necessary precision. The cognitive mechanisms for the selection of appropriate frames of reference are still not fully understood. This study investigated the effect of changing visual and kinesthetic frames of reference during wrist pointing, simulating activities typical for tele-operations. METHODS: using a robotic manipulandum, subjects had to perform center-out pointing movements to visual targets presented on a computer screen, by coordinating wrist flexion/extension with abduction/adduction. We compared movements in which the frames of reference were aligned (unperturbed condition with movements performed under different combinations of visual/kinesthetic dynamic perturbations. The visual frame of reference was centered to the computer screen, while the kinesthetic frame was centered around the wrist joint. Both frames changed their orientation dynamically (angular velocity = 36 degrees /s with respect to the head-centered frame of reference (the eyes. Perturbations were either unimodal (visual or kinesthetic, or bimodal (visual+kinesthetic. As expected, pointing performance was best in the unperturbed condition. The spatial pointing error dramatically worsened during both unimodal and most bimodal conditions. However, in the bimodal condition, in which both disturbances were in phase, adaptation was very fast and kinematic performance indicators approached the values of the unperturbed condition. CONCLUSIONS: this result suggests that subjects learned to exploit an "affordance" made available by the invariant phase relation between the visual and kinesthetic frames. It seems that after detecting such invariance, subjects used the kinesthetic input as an informative signal rather than a

    Once considered uncommon, spontaneous dissection of the carotid artery is an increasingly recognized cause of stroke, headache, cranial nerve palsy, or ophthalmologic events, especially in young adults. Even in the presence of existing signs and symptoms, the diagnosis can be missed by experienced physicians of all specialties. We report a case of spontaneous internal carotid artery dissection in a 38-year-old woman with a cortical stroke and visual disturbances as initial symptoms. The diagnosis was confirmed by magnetic resonance imaging/angiography and by angiography. Prompt anticoagulation was instituted, and the patient had complete resolution of symptoms. Cervicocephalic arterial dissection should be included in the differential diagnosis of the causes of cerebrovascular events.

  19. Motor imagery modulation of postural sway is accompanied by changes in the EMG-COP association.

    2014-08-08

    Motor imagery (MI) performed in an upright stance promotes increases in postural sway without changes in usual amplitude measures of calf muscle EMG. However, postural muscle activity can also be determined from the temporal association between EMG and center of pressure (COP) displacements. In this study we investigated whether the MI modulation of postural sway is accompanied by changes in EMG-COP association. Surface EMG from the lateral gastrocnemius (LG) muscle and COP coordinates were collected from 12 subjects while they imagined themselves performing a rising on tiptoes movement via kinesthetic or visual imagery. As a control condition subjects were requested to imagine singing a song. The standard deviation of the forward-backward COP sway and the coefficient of variation of the EMG were calculated and compared across tasks. The degree of association between COP sways and LG activity was evaluated through a cross-correlation function. Kinesthetic imagery promoted a larger COP displacement than both visual and control imagery (pEMG amplitude was observed across imagery tasks (p=0.08). Crucially, we found a stronger EMG-COP association during kinesthetic imagery compared to control imagery (p=0.02), whereas the EMG-COP association in visual imagery was not different from that observed during kinesthetic or control imagery (p>0.19). In conclusion, kinesthetic imagery resulted in a higher EMG-COP temporal association. Subliminal fringe mechanisms may account for the imagery effects on muscle activity and postural sway during upright stance.

  20. Sensory subtraction in robot-assisted surgery: fingertip skin deformation feedback to ensure safety and improve transparency in bimanual haptic interaction.

    Meli, Leonardo; Pacchierotti, Claudio; Prattichizzo, Domenico

    2014-04-01

    This study presents a novel approach to force feedback in robot-assisted surgery. It consists of substituting haptic stimuli, composed of a kinesthetic component and a skin deformation, with cutaneous stimuli only. The force generated can then be thought as a subtraction between the complete haptic interaction, cutaneous, and kinesthetic, and the kinesthetic part of it. For this reason, we refer to this approach as sensory subtraction. Sensory subtraction aims at outperforming other nonkinesthetic feedback techniques in teleoperation (e.g., sensory substitution) while guaranteeing the stability and safety of the system. We tested the proposed approach in a challenging 7-DoF bimanual teleoperation task, similar to the Pegboard experiment of the da Vinci Skills Simulator. Sensory subtraction showed improved performance in terms of completion time, force exerted, and total displacement of the rings with respect to two popular sensory substitution techniques. Moreover, it guaranteed a stable interaction in the presence of a communication delay in the haptic loop.
