    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 vertical planes. The findings of this study can be implemented in people who have to do repeated arm and neck movements, by using ergonomically effective chairs with proper arm supports. This might help in prevention and treatment of neck pain. PMID:27255483

    Within the Human-Computer Interaction community there is a growing interest in designing for the whole body in interaction design. The attempts aimed at addressing the body have very different outcomes spanning from theoretical arguments for understanding the body in the design process, to more...... practical examples of designing for bodily potential. This paper presents Kinesthetic Interaction as a unifying concept for describing the body in motion as a foundation for designing interactive systems. Based on the theoretical foundation for Kinesthetic Interaction, a conceptual framework is introduced...... to reveal bodily potential in relation to three design themes – kinesthetic development, kinesthetic means and kinesthetic disorder; and seven design parameters – engagement, sociality, movability, explicit motivation, implicit motivation, expressive meaning and kinesthetic empathy.

    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.

    Musicians use different kinds of imagery. This review focuses on kinesthetic imagery, which has been shown to be an effective complement to actively playing an instrument. However, experience in actual movement performance seems to be a requirement for a recruitment of those brain areas representing movement ideation during imagery. An internal model of movement performance might be more differentiated when training has been more intense or simply performed more often. Therefore, with respect to kinesthetic imagery, these strategies are predominantly found in professional musicians. There are a few possible reasons as to why kinesthetic imagery is used in addition to active training; one example is the need for mental rehearsal of the technically most difficult passages. Another reason for mental practice is that mental rehearsal of the piece helps to improve performance if the instrument is not available for actual training as is the case for professional musicians when they are traveling to various appearances. Overall, mental imagery in musicians is not necessarily specific to motor, somatosensory, auditory, or visual aspects of imagery, but integrates them all. In particular, the audiomotor loop is highly important, since auditory aspects are crucial for guiding motor performance. All these aspects result in a distinctive representation map for the mental imagery of musical performance. This review summarizes behavioral data, and findings from functional brain imaging studies of mental imagery of musical performance. PMID:23781196

    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.

    2015-12-01

    Full Text Available This review-essay of Keith Moxey’s Visual Time: The Image in History (2013 addresses recent theoretical work on images, historiography, and temporality. It does so by critiquing preexisting methodological issues such as linear chronology, ekphrasis, and contemporaneity. In addition to reviewing how Moxey deals with the problematic of temporality in art historical practice, this review-essay develops its own methodological approach through the concept of transmissibility. Transmissibility is a theoretical methodology for how to approach the relation between temporality and artworks that draws on the work of Gilles Deleuze and Félix Guattari. Transmissibility stems from a desire to arrive at an art history capable of articulating the complex epistemic and aesthetic power of an artwork. In other words, an artwork as a material, expressive reality, a conjunction of content and expression, statement and visibility, sensible and intelligible. It remains to us as art historians to think a philosophy of history wherein artworks embody transmissibility (survival, anachronism, memory, becoming: the full complexity of temporality.

    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.

  5. 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...

  7. 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.

    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.

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

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

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

    Directory of Open Access Journals (Sweden)

    Benedikt Valerian Ehinger

    2014-02-01

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

    The aim of this study was to identify brain regions involved in motor imagery and differentiate two alternative strategies in its implementation: imagining a motor act using kinesthetic or visual imagery. Fourteen adults were precisely instructed and trained on how to imagine themselves or others perform a movement sequence, with the aim of promoting kinesthetic and visual imagery, respectively, in the context of an fMRI experiment using block design. We found that neither modality of motor imagery elicits activation of the primary motor cortex and that each of the two modalities involves activation of the premotor area which is also activated during action execution and action observation conditions, as well as of the supplementary motor area. Interestingly, the visual and the posterior cingulate cortices show reduced BOLD signal during both imagery conditions. Our results indicate that the networks of regions activated in kinesthetic and visual imagery of motor sequences show a substantial, while not complete overlap, and that the two forms of motor imagery lead to a differential suppression of visual areas.

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

    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.

    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.

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

    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.

  6. Adjusting ability and sensibility for an accident

    International Nuclear Information System (INIS)

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

    Lott, Susan Nitzberg; Carney, Aimee Syms; Glezer, Laurie S; Friedman, Rhonda B

    2010-11-01

    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

    1991-01-01

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

  12. Deduction of the Sensible Heat Flux from SODAR Data

    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.

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

    2015-07-01

    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.

    1988-01-01

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

    2015-12-01

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

  20. Three symptoms of contemporary social sensibility in Mexico

    Directory of Open Access Journals (Sweden)

    Armando Villegas Contreras

    2015-12-01

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

  2. 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.

    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.

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.

    Measurement of evaporation independent from evapotranspiration remains a major challenge for quantifying water fluxes in the soil-plant-atmosphere system. Methodology based on soil sensible heat balance (SHB) has been developed to measure in situ, sub-surface soil water evaporation with heat-pulse sensors. Soil sensible heat flux and change in heat storage are measured at multiple depths near the soil surface, and a simple energy balance calculation is applied to determine latent heat flux (i.e., evaporation) as a residual. For bare surface conditions, comparison of SHB to micrometerological (Bowen ratio) and micro-lysimeter approaches indicates strong correlation (r2 = 0.96) with near 1:1 relationship and root mean square error of 0.2 mm/d. Recent efforts to apply SHB methodology in row-crop (maize) and vineyard systems demonstrate the potential for quantifying evaporation separate from evapotranspiration. For the maize system, SHB evaporation estimates differed from micro-lysimeters by evaporation from evapotranspiration.

    International Nuclear Information System (INIS)

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

    1997-01-01

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

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

  15. 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

    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.

    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.

    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.

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

    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.

    Body surface temperature can be used to evaluate thermal equilibrium in animals. The bodies of broiler chickens, like those of all birds, are partially covered by feathers. Thus, the heat flow at the boundary layer between broilers' bodies and the environment differs between feathered and featherless areas. The aim of this investigation was to use linear regression models incorporating environmental parameters and age to predict the surface temperatures of the feathered and featherless areas of broiler chickens. The trial was conducted in a climate chamber, and 576 broilers were distributed in two groups. In the first trial, 288 broilers were monitored after exposure to comfortable or stressful conditions during a 6-week rearing period. Another 288 broilers were measured under the same conditions to test the predictive power of the models. Sensible heat flow was calculated, and for the regions covered by feathers, sensible heat flow was predicted based on the estimated surface temperatures. The surface temperatures of the feathered and featherless areas can be predicted based on air, black globe or operative temperatures. According to the sensible heat flow model, the broilers' ability to maintain thermal equilibrium by convection and radiation decreased during the rearing period. Sensible heat flow estimated based on estimated surface temperatures can be used to predict animal responses to comfortable and stressful conditions.

    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.

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

    International Nuclear Information System (INIS)

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

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

    Science.gov (United States)

    Ma, Zhanhong; Fei, Jianfang

    2016-04-01

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

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.

    The translator’s subjectivity has been applied to analyze two Chinese versions of Sense and Sensibility, illustrating the subjective factors involved in the two translators. The exertion the translator’s subjectivity brings about different translations of the same original with distinct styles, and each translation justifies the value of its existence. Literary translation criticism should take the translator’s subjectivity into account, so a more sound and comprehensive study of the process of literary translation can be done.

    The value of neurovascular island skin flap transfers for digit tip surfacing has been evaluated in 13 patients. A computer assisted sensory evaluation was carried out on six of the patients. All patients were satisfied with the procedure. Sensory acuity did not appear to diminish with time and sensory misreference was not a major functional problem. We suggest that the neurovascular island flap, when available, is still an excellent procedure for restoration of useful digit tip sensibility. PMID:3670039

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

    Full Text Available 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.

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

    Full Text Available 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.

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

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

    Directory of Open Access Journals (Sweden)

    M. J. Savage

    2010-01-01

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

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

    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.

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

    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.

Nuestros resultados ofrecen una primera aproximación al conocimiento de los aspectos de gestión de las limitaciones de salud que menoscaban la capacidad de los trabajadores para responder a las demandas de trabajo.

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

    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.

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

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

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

    Desert sand from the United Arab Emirates (UAE) is considered as a possible sensible heat, thermal energy storage (TES) material. Its thermal stability, specific heat capacity and tendency to agglomerate are studied at high temperatures. The analyses show that it is possible to use desert sand as a TES material up to 800-1000 °C. Above 800 °C, weak agglomeration effects start to become significant. The samples become solid above 1000 °C. This may represent a major operating limit depending on the handling mechanism in place for the possible transport of the sand. The sand chemical composition is analyzed with the XRF and XRD techniques, which reveal the dominance of quartz and carbonates. Finally, the spectral absorptivity of the samples is measured before and after a thermal cycle, as it may be possible to use the desert sand not only as a TES material but also as a direct solar absorber.

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

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

    International Nuclear Information System (INIS)

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

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

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

    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.

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

    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.

    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.

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

    In land many surface models, which account for the energy balance at the land surface, subsurface heat transport is an important component that reciprocally influences ground, sensible and latent heat fluxes, and net radiation. The applied subsurface heat transport parameterizations are commonly simplified for computational efficiency. A major simplification is the disregard of the sensible heat of rain and convective subsurface heat flow, i.e. the transport of heat through moisture redistribution, which basically decouples heat transport from moisture transport at the land surface and in the subsurface. In the presented analysis, the influence of sensible heat of rain and convection on the energy balance is studied using a coupled model that integrates a subsurface moisture and energy transport model with a land surface model. It is shown that all components of the land surface energy balance depend on the sensible heat of rain. The strength of the dependence is related to the rain rate, and the temperature difference between the rain water and the soil surface. The rain water temperature is a parameter rarely measured in the field that introduces uncertainty in the calculations and is approximated using the either the air or wet bulb temperatures in different simulations. In addition it is shown that the lower boundary condition for closing the problem of subsurface heat transport has strong implications on the energy balance under dynamic equilibrium conditions. Comparison with measured data from the Meteostation Haarweg, Wageningen, The Netherlands, shows good agreement and suggests the usefulness of the proposed approach.

    International Nuclear Information System (INIS)

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

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

    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.

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.

    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.

    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.

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

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

    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.

    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?

    2008-01-01

    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.

    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.

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 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.

    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.

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

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

    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.

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

    The 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

    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 use of handheld myometry (RIHM for manual muscle testing, despite more specifically targeting thenar muscles, was less responsive than grip or tripod

    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

    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.

    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.

    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

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

    Schieldge, John

    2000-01-01

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

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

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

    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.

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

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

    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.

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

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

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

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

    International Nuclear Information System (INIS)

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

    . 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.

    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.

    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.

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

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

    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 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.

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.

    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.

    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

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

    International Nuclear Information System (INIS)

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

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

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

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

    Full Text Available En el presente estudio se establecieron relaciones entre la respuesta materna sensible, el apego y la obesidad infantil. El diseño fue de tipo descriptivo-exploratorio, se utilizó entrevista semiestructurada, el Child Attachment Interview y observación no participante. Los resultados señalan que los niños(as con obesidad presentan un apego inseguro y que la madre responde con un desacoplamiento frente a las necesidades del hijo; la emisión de respuestas de negación del problema, descuido, invalidación de la experiencia subjetiva y falta de sensibilidad para detectar el hambre y la saciedad del hijo, se relacionan con la obesidad. Se concluye que la intervención en obesidad debe incluir la relación afectiva madre-hijo y se proyecta la posibilidad de prevención del trastorno.

    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.

    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

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

    Under the condition of developed capitalist system and modernity,reason and sensibility experienced their own crises and self-denial in the process of history;at the same time,they also experienced opposition and compromise with each other.Under the basis of imparting and inheriting classical Marxism and critical understanding of reason,Marcuse put forward the new sensibility for the purpose of rebuilding human sensibility,regaining human instinct and realizing human liberation.This theory provided a new angle for enriching revolutionary theories of Marxism and further understanding relevant problems of reason and sensibility.Moreover,it was a good try in order to regain theoretical value of sense and realize the compromise of sense and sensibility.%在发达资本主义社会制度和现代性条件下,理性和感性在历史的现实运动中经历了自身的危机和自我否定,也上演了相互间的对立与调和。马尔库塞在对经典马克思主义的传承和对理性进行批判性理解的基础之上,提出了旨在重建人的感性、恢复人的本能、实现人的解放的新感性观。这为丰富马克思主义革命理论、进一步思考理性和感性有关问题提供了新的视角,为恢复感性的理论价值、实现理性与感性的和解做出了有益尝试。

  8. Sensibility of grey particle production system to energy and centrality in 60A and 200A GeV 16O-Nucleus interactions

    The grey particle production following 60 A and 200A GeV 16O interactions with emulsion nuclei is investigated at different centralities. The evaporated target fragment multiplicity is voted as a centrality parameter. The target size effect is examined over a wide range, where the C, N and O nuclei present the light target group while the Br and Ag nuclei are the heavy group. In the framework of the nuclear limiting fragmentation hypothesis, the grey particle multiplicity characteristics depend only on the target size and centrality while the projectile size and energy are not effective. The grey particle is suggested to be a multisource production system. The emission direction in the 4π space depends upon the production source. Either the exponential decay or the Poisson’s peaking curves are the usual characteristic shapes of the grey particle multiplicity distributions. The decay shape is suggested to be a characteristic feature of the source singularity while the peaking shape is a multisource super-position. The sensibility to the centrality varies from a source to other. The distribution shape is identified at each centrality region according to the associated source contribution. In general, the multiplicity characteristics seem to be limited w.r.t. the collision system centrality using light target nuclei. The selection of the black particle multiplicity as a centrality parameter is successful through the collision with the heavy target nuclei. In the collision with the light target nuclei it may be qualitatively better to vote another centrality parameter.

    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.

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

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

    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.

    Highlights: → Vascular Entothelial Growth Factor Receptor-1 was used as a biorecognition element as a first time in the literature. → Electrochemical impedance spectroscopy, as a measurement principle was used for analysis of VEGF-R1/VEGF interaction as a first time. → A layer-by-layer immobilization procedure enhanced the sensibility of the biosensor. → The biosensor could detect vascular endothelial growth factor in the range of 100-600 femtogram mL-1. - Abstract: In the presented research, a novel, ultra sensitive biosensor for the impedimetric detection of vascular endothelial growth factor (VEGF) is introduced. The human vascular endothelial growth factor receptor 1 (VEGF-R1, Flt-1) was used as a biorecognition element for the first time. The immobilization of VEGF-R1 on glassy carbon electrodes was carried out using layer-by-layer covalent attachment of VEGF-R1. The electrochemical properties of the layers constructed on the electrodes were characterized by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The differences in electron transfer resistance (Ret) between the working solution and the biosensor surface, recorded by the redox probe K3[Fe(CN)6]/K4[Fe(CN)6], confirmed the binding of VEGF to VEGF-R1. The new biosensor allowed a detection limit of 100 fg mL-1 with a linear range of 100-600 fg mL-1 to be obtained. The biosensor also exhibited good repeatability (with a correlation coefficient of 1.95%), and reproducibility.

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

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

    Full Text Available À Madagascar, depuis quelques années, la sauvegarde de la biodiversité est devenue une priorité pour le gouvernement. Avec l’aide des partenaires étrangers le pays étend actuellement de manière spectaculaire son réseau d’espaces protégés. Malgré l’intégration de la gouvernance participative sur le terrain, ce mouvement s’accompagne d’une très forte déstabilisation des communautés locales. Parallèlement, le pays qui affronte des crises multiples (crise économique latente et crises politiques à répétition est le théâtre d’un formidable « boum » des activités informels en général et de l’artisanat minier en particulier. Dans bien des cas, lorsque la gestion des milieux sensible est retirée aux communautés locales au profit d’acteurs institutionnels, on assiste au développement de ces activités destructrices. Pour lutter contre cet effet pervers de l’institutionnalisation de la protection environnementale, il devient urgent de disposer d’un plus large panel de systèmes de gouvernance. Ceux-ci doivent être conçus pour s’adapter aussi bien que possible à la multitude de contextes rencontrés, en prenant en compte l’ensemble des acteurs, qu’ils soient formels, issus de la société traditionnelle, ou informels.In Madagascar, during the last few years, conservation of biodiversity has become a major priority for the government.

    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)

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

    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.

    Work was carried out on two topics of principal importance to current progress in virtual environment research at NASA Ames and elsewhere. The first topic was directed at maximizing the temporal dynamic response of visually presented Virtual Environments (VEs) through reorganization and optimization of system hardware and software. The final results of this portion of the work was a VE system in the Advanced Display and Spatial Perception Laboratory at NASA Ames capable of updating at 60 Hz (the maximum hardware refresh rate) with latencies approaching 30 msec. In the course of achieving this system performance, specialized hardware and software tools for measurement of VE latency and analytic models correlating update rate and latency for different system configurations were developed. The second area of activity was the preliminary development and analysis of a novel kinematic architecture for three Degree Of Freedom (DOF) haptic interfaces--devices that provide force feedback for manipulative interaction with virtual and remote environments. An invention disclosure was filed on this work and a patent application is being pursued by NASA Ames. Activities in these two areas are expanded upon below.

    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.

    2014-09-01

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

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

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

The daytime momentum flux cospectra inside the canopy and in the subcanopy are characterized by a relatively large cross-wind component, likely due to the extremely light and variable winds, such that the definition of a mean wind direction, and subsequent partitioning of the momentum flux into along- and cross-wind components, has little physical meaning. Positive values of both momentum flux components in the subcanopy contribute to upward transfer of momentum, consistent with the observed mean wind speed profile. In the canopy at night at the smallest resolved scales, we find relatively large momentum fluxes (compared to at larger scales, and increasing vertical velocity variance with decreasing time scale, consistent with very small eddies likely generated by wake shedding from the canopy elements that transport momentum but not heat. We find unusually large values of the velocity aspect ratio within the canopy, consistent with enhanced suppression of the horizontal wind components compared to the vertical by the canopy. The flux-gradient approach for sensible heat flux is found to be valid for the subcanopy and above-canopy layers when considered separately; however, single source approaches that ignore the canopy fail because they make the heat flux appear to be counter-gradient when in fact it is aligned with the local temperature gradient in both the subcanopy and above-canopy layers. Modeled sensible heat fluxes above dark warm closed canopies are likely underestimated using typical values of the Stanton number.

    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.

  9. Communication on radiation safety: ability and sensibility

    International Nuclear Information System (INIS)

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

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

  13. 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.

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

    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)

  19. Emitter clogging sensibility with increasing biofilm components under reclaimed water drip irrigation condition%再生水滴灌灌水器附生生物膜生长对堵塞的影响

    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.

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

  6. Learning compliant manipulation through kinesthetic and tactile human-robot interaction.

    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.

This could be the result of a lack of mandatory, quality sexual health education in schools, combined with larger scale social issues. Young females, in particular, reported feelings of shame when visiting sexual health clinics which on occasion may compel them to lie about their sexual history to a practitioner in order to protect a ‘fragile sexual reputation’(1. In response to the recommendations of FPA and the aforementioned public health statistics, this session was developed to improve student understanding of sexual health and of the risks associated with different sexual behaviors. Another aim was, by integrating information about the importance of regular sexual health check-ups into sexual health education in schools, to reduce the associated feelings of shame across the young female population. The activity was carried out with two classes of Year 12 students (16-17 years in an independent school in the London borough of Lewisham. The session builds on education about STIs, which is part of the national science curriculum, and extends concepts about transmission to the most common STIs prevalent within the population aged 16-24.

    2016-09-01

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

    Full Text Available This qualitative study focused on proxemic feelings and feelings of detachment and ambiguity among professors-nurses concerning their experiences. This study aimed to reveal the meanings of sensibility held by being-professor-nurse in teaching and learning to be and do nursing. The theoretical-philosophical support is based on Merleau-Ponty's existential phenomenological approach and the hermeneutics phenomenology of Paul Ricoeur was used. Nineteen professors-nurses from a Higher Education institution in the South of Brazil were interviewed between November and December 2006. Sensibility was revealed as the capacity to observe details in order to intervene in a situation the best way possible, and also as a way to break with exclusive models of the cognitive-instrumental rationality of science and technique, since sensibility is the basis for developing other ways of teaching and learning to be and do Nursing.Esta es una investigación cualitativa, enfocando los sentimientos de proxemia, de distanciamiento y de ambigüedad de los docentes enfermeros/as a partir de lo vivido.

    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.

In fact, the bulk transfer coefficients change not only with atmospheric stabilities, but also with the air motion and thermodynamic properties of the surface boundary layer. In this paper, the bulk transfer coefficients of momentum and sensible heat are determined by using the data observed by the eddy correlation system and those of the average wind velocity and temperature gradients over the Xilin Guole semiarid grassland in May, 2008. The relations between the bulk transfer coefficients and the gradients in Richardson numbers are analyzed, and the relationship between the bulk transfer coefficients and atmospheric stabilities is also studied. Finally, the changes of momentum bulk transfer coefficients

    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

    2004-09-01

    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.

    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.

    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.

    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.

    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.

This was done to asses the L D50 and the optimum irradiation range for breeding purposes. The irradiated scions (20 per treatment) were grafted on Mexican rootstocks. Four months after irradiation lethality reached 100 % at 45 Gy. The L D50 was estimated at 29.54 Gy and the optimum irradiation dose for breeding ranged between 1.48 and 24.51 Gy which correspond to 70 % and 60 % of survival rate, respectively. (Author)

    Full Text Available El análisis de los aspectos sensibles de la vida pública o, en otras palabras, el ritmanálisis de Henri Lefebvre, tiene un enorme potencial heurístico para el estudio de las ciudades y sus imágenes. Este texto sostiene que las imágenes de la ciudad también están hechas de paisajes sonoros; y que los sonidos urbanos pueden revelar no sólo la evolución urbana, sino también el modo de organización actual de los entornos sociales de las ciudades. Sin embargo, las Ciencias Sociales se han relacionado de manera irregular con esas sonoridades. Con incursiones en los dominios de la Sociología y de la Geografía, este texto sostiene la necesidad de conceder una mayor atención a los campos y paisajes sonoros de las ciudades, a fin de detectar con más rigor sus trayectorias y configuraciones sociales.A análise dos aspectos sensíveis da vida pública ou, por outras palavras, a ritmanálise de H.

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

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

    Objective To study the effects of all-trans-retinoic acid (ATRA) on chemotherapeutics sensibility and expression of Survivin in human LoVo colon cancer cell line, and to provide a theoretical basis for clinical application of ATRA.Methods Flow cytometer (FCM) was used to detect the cell cycle of LoVo colon cancer cell line after treated with various dose of ATRA (10-5 mol/L, 10-6 mol/L and 10-7 mol/L)for 24 h, 48 h, 72 h, 5 d, 9 d and 15 d respectively.The cells were divided into ATRA group (10-6 mol/L)and control group (cultured in routine medium RPMI1640).Meanwhile, each group were divided into subgroups respectively treated with 0 g/L, 2 g/L, 4 g/L and 6 g/L 5-fluorouracil(5-FU) , or with 0 mg/L, 200 mg/L, 400 mg/L and 600 mg/L mitomycin (MMC).MTT assay was used to detect the viability of cells so as to analyze the change in chemotherapeutics sensibility.Drug interactions were analyzed according to the interaction effects.Staining with acridine orange (AO) and ethidium bromide (EB) was used to study the apoptosis in control group(RPMI1640) , ATRA group (10-6 mol/L), 5-FU group (4 g/L), MMC group (400 mg/L), ATRA (10-6 mol/L) + 5-FU (4 g/L) group and ATRA (10-6 mol/L) + MMC (400 mg/L) group.The expression of Survivin in the LoVo cell line was investigated by immunofluorescence technique.Results Compared with the control group, the percentage of cell in Go-G1 phase increased after interference with various doses of ATRA for 24 hours, peaked at 48 h, and gradually decreased afterwards, while the percentage of cells in stages S and G2-M decreased, reach the trough at 48 h, and then increased gradually.Effects of 10-6 mol/L ATRA were most significant at all time spots.Compared with control group, 10-6 mol/L ATRA reduced cell survival rate (P<0.05),and the survival rates in control subgroups treated with various doses of 5-FU were significantly higher than those in ATRA group (all P<0.05).In MMC-treated control group, cell survival rate with 200 mg/L MMC was lower

  10. Design and implementation of remote robotic control system for nuclear power plant application achieved through kinesthetic force feedback model

    International Nuclear Information System (INIS)

    The technology of telerobotic control through a universal and transparent Man-Machine Interface is a growing field of robotics research in today's industrial scenario because of its promising application in hazardous and unstructured environments. The joystick, a sophisticated information receiver-translator-transmitter device, serves as a Man-Machine Interface for telerobots. The present paper describes the development paradigms of a remote control system for a planar four degrees-of-freedom joystick following position feed-forward force/torque feedback strategy in a bi-lateral mode. This joystick based control technology is designed to actuate an industrial robot working in nuclear power plant. The remote control system has been illustrated with model, algorithm, electronic hardware and software routines along with experimental results in order to have effective telemanipulation

    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.

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

    Directory of Open Access Journals (Sweden)

    2004-11-01

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

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

    Energy Technology Data Exchange (ETDEWEB)

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

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

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

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

    International Nuclear Information System (INIS)

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

For amaranth, the collection A1 showed the best feedback among 0 and 300 Gy in the 15 studied variables, the one that stood out was the 200 Gy doses in seed weight per plant (SWP) with 1.33 g. Huauzontle H3 to 50 Gy showed the best results for weight and seed diameter. High doses (from 300 to 450 Gy) showed higher percentage of mortality in spite of the fact that in some cases germination was stimulated. It is advisable for future studies about these pseudo cereals doses among 50 and 250 Gy. (Author)

    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.

    Accelerations in the flow over forests generate coherent structures which locally enhance updrafts and downdrafts, forcing rapid exchanges of energy and matter. Here, observations of the turbulent flow are made in a highly heterogeneous black spruce boreal forest in Fairbanks, Alaska at ~2.6 h (12 m) and ~0.6 h (3 m), where h is the mean canopy height of 4.7 m. Wavelet analysis is used to detect coherent structures. The sonic temperature and wind data cover 864 half-hour periods spanning winter, spring, and summer. When mean global statistics of structures are analyzed at the two levels independently, results are similar to other studies. Specifically, an average of eight structures occurs per period, their mean duration is 85 s, and their mean heat flux contribution is 48%. However, this analysis suggests that 31% of the structures detected at 2.6 h, and 13% at 0.6 h, may be influenced by wave-like flow organization. Remarkably, less than 25% of the structures detected occur synchronously in the subcanopy and above canopy levels, which speaks robustly to the lack of flow interaction within only nine vertical meters of the forest.

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

    International Nuclear Information System (INIS)

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

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.

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.

    2011-01-01

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

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

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

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

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

    International Nuclear Information System (INIS)

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

    2015-03-01

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

  10. 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.

    This study reports the supramolecular assembly of a silver nanoparticle-naphthalene-1-sulphonic acid-reduced graphene oxide composite (Ag-NA-rGO) and its utilization to fabricate a highly sensitive and selective gas sensor. The prepared supramolecular assembly acted not only as a non-covalent functionalization platform (π-π interaction) but was also an excellent scaffold to fabricate a highly sensitive and selective low concentration NO2 gas sensor. The prepared composites were characterized using several techniques, which revealed that the graphene sheets were dispersed as ultrathin monolayers with a uniform distribution of silver nanoparticles. The fabricated multilevel structure exhibited an excellent sensing performance, i.e. 2.8 times better, towards 10 ppm NO2 compared to the NA-rGO and rGO based sensors. Apart from its high sensitivity, superior reversibility and selectivity, the prepared supramolecular assembly exhibited an outstanding linear response over the large concentration range from 1 ppm to 10 ppm. The obtained results demonstrate that the prepared supramolecular assembly holds great potential in the fabrication of efficient and effective low-concentration NO2 gas sensors for practical applications.This study reports the supramolecular assembly of a silver nanoparticle-naphthalene-1-sulphonic acid-reduced graphene oxide composite (Ag-NA-rGO) and its utilization to fabricate a highly sensitive and selective gas sensor.

    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.

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

    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.

    1987-01-01

    Over a recent 8-year period, Septisol Foam (0.23% hexachlorophene in a 46% ethyl alcohol base) alone was used to prepare the hands and forearms of the author's surgical team. In 3480 cases, only 11 postoperative infections were encountered, for an incidence of 0.3%. All 11 infections involved patients who underwent gastrointestinal surgery and/or who had high-risk factors such as cancer, hypertension, diabetes mellitus, perforated appendix, emergency surgery, age over 65 years, and foreign bodies in the form of hemodialysis access shunts. Septisol Foam is an effective bacteriostatic agent that minimizes the risk of dermatitis and offers sufficient antibacterial protection without supplementary handwashing. When used according to the method described here, the foam eliminates the need for scrub brushes and reduces the total scrub time to approximately 2 minutes in each case. In addition to being safe, effective, and easy to use, this method results in a marked decrease in water consumption and considerable monetary savings.

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

Five false positive cases were observed, characterized by microbiological growth in Dermatobac® but not confirmed by endometrial cytology, determining specificity of 85%. However, the results did not compromise the efficiency of Dermatobac® system given all contaminants presented differentiated morphology and higher growing time (P<0.05 when compared to the major etiological agents of equine fungal endometritis. The Dermatobac® system proved to be efficient for the macroscopic diagnosis of fungal endometritis in horses, showing conclusive information only after 24 hours of culture.

    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.

    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.

  14. 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.

  17. 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.

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

    CERN Document Server

    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...

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

    Directory of Open Access Journals (Sweden)

    A. Capet

    2012-12-01

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

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

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

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

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

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

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

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

    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.

    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.

  11. 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.

    2015-12-01

    Full Text Available This paper deals with the numerical simulation of heat transfer and entropy generation in a 2D square enclosure for convective melting. A thermal lattice Boltzmann method (TLBM is used to handle the study, which has been conducted for Prandtl numbers from 0.02 to 70 at Rayleigh numbers of 104 and 105. The results are presented in terms of the total entropy generation, average Bejan number and average Nusselt number. Within the range considered for the key parameters, the entropy generation is found to be controlled by the heat transfer loss for low Prandtl numbers. However, for the large Prandtl numbers, its variation is dominated by shearing losses. Moreover, the presence of the latent heat state decreases the overall thermodynamic losses while increasing the quantity of heat transferred.

    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.

  19. 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.

  20. Study of the sensibility of the Antares neutrino telescope to very high energy photons: Contribution to the time calibration of the detector

    International Nuclear Information System (INIS)

    From the sea-floor, the 900-odd photomultiplier tubes of the Antares neutrino telescope scrutinize the abysses attempting to discern, amid bioluminescence and marine radioactivity, Cerenkov photons emitted by muons from astrophysical neutrinos, and to distinguish these muons from those generated by air showers produced by cosmic rays. Antares has been collecting data since 2006; this feat of engineering has paved the way for submarine neutrino astronomy: Antares is expected to be the forerunner of a larger instrument, KM3NeT. Telescope's performance is characterized in part by its angular resolution. In the case of Antares, the angular resolution is directly related to the time resolution of the detector's elements. This manuscript presents a correction for one of the main sources of deterioration of this time resolution, the walk effect induced by the set up of a fixed threshold for triggering the photomultiplier tubes signal. This correction, implemented in the official software chain of the Antares collaboration, improves in particular the events reconstruction quality estimator. This implementation allows further optimizations. The author also attempts to evaluate, using a complete Monte-Carlo simulation, the possibility of using very high energy photon sources as calibrated muon beams in order to estimate the absolute pointing and the angular resolution of the telescope. Although limited by large uncertainties, it is demonstrated that the possibility to detect such sources is extremely small. In addition, it is shown that the atmospheric neutrino background induced by very high-energy photons is negligible. (author)

    为保证涡轮盘满足适航规章的安全性要求,采用单向流固耦合数值方法,研究了转静系旋转盘腔以基比切夫数表示的盘缘加热热流密度的变化对冷却效果的影响,并依据旋转盘腔冷却问题的工程评价体系对旋转盘腔的冷却效果进行评价。研究结果表明:基比切夫数的变化对于旋转盘腔的流动结构和流动阻力基本没有影响,对盘面的换热效果影响也较微弱,仅引起转盘迎风面热流密度和温度的改变。同时,温度分布的改变导致了与温度梯度紧密相关的热应力水平发生变化。随着热流密度的增加,转盘整体应力水平上升,并且盘缘附近区域的等效应力提高的幅度大于中心区域。当基比切夫数高于临界值后,最大等效应力值从转盘中心转移到盘缘。基比切夫数的变化能够从部件承受能力和实际使用载荷两方面对涡轮盘的失效概率产生较大影响,因此,在涡轮盘腔的设计阶段,需要考虑基比切夫数对涡轮盘安全性的影响。%Fluid-Structure-Interaction numerical method was applied to investigate the effects of the heat flux, which is presented as Chebyshev number, on the cooling of the rotating cavity. The cooling effect was also evaluated in accordance with an engineering evaluation system, which includes resistance evaluation, heat transfer evaluation and stress distribution evalua- tion, in order to ensure the safety of the turbine disk. The results show that the heat flux and the temperature distribution of the disk exhibited the influence of the variation of the heat flux on the outer rim of the disk which has no effect on the fluid structure of the rotating cavity and the flow resistance. Meanwhile, the thermal stress related to the temperature gradient can be affected. The stress level of the disk rises as increasing the Chebyshev number. The stress on the outer rim of the disk grows greater than it on the inner rim. The peak stress transfers from the centre to the disk rim while the Chebyshev number exceeds the critical value. Therefore, the change of the Chebyshev number has an effect on the failure probability of the turbine disk from both the material affordability and the working stress.

For amaranth, the collection A1 showed the best feedback among 0 and 300 Gy in the 15 studied variables, the one that stood out was the 200 Gy doses in seed weight per plant (SWP) with 1.33 g. Huauzontle H3 to 50 Gy showed the best results for weight and seed diameter. High doses (from 300 to 450 Gy) showed higher percentage of mortality in spite of the fact that in some cases germination was stimulated. It is advisable for future studies about these pseudo cereals doses among 50 and 250 Gy. (Author)

  6. The Sensible Heat Flux in the Course of the Year at Ny-Ålesund, Svalbard: Characteristics of Eddy Covariance Data and Corresponding Model Results

    2015-01-01

    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.

    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.

    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.

    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.

    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. PMID:27155266

  19. Study of the distribution of radiation dose in radio sensible organs arising from dental X-ray devices using the Monte Carlo method

    International Nuclear Information System (INIS)

    This project used the MCNPX code to estimate the radiation doses from dental X-rays apparatus received for patients on the radiological services. On the research several steps were taken as: The construction of an input file to the MCNPX code containing related information: the geometries of dental X-ray apparatus and the ionizing chamber. To the input file was added a virtual model of head. However, was performed the validation of simulation with the code through experimental measurements directly into a real dental X-ray apparatus. With it conclude that the results are very representative, because the entrance skin dose obtained through simulation match with the results found in the literature. Also, we noted that entrance skin, the teeth and the upper and lower jaw presented the higher doses, and the radiosensitive organs did not receive relevant doses, this was due to good collimation of the equipment.

  20. From mad cows to sensible blood transfusion: the risk of prion transmission by labile blood components in the United Kingdom and in France.

    2009-04-01

    Transfusion transmission of the prion, the agent of variant Creutzfeldt-Jakob disease (vCJD), is now established. Subjects infected through food may transmit the disease through blood donations. The two nations most affected to date by this threat are the United Kingdom (UK) and France. The first transfusion cases have been observed in the UK over the past 5 years. In France, a few individuals who developed vCJD had a history of blood donation, leading to a risk of transmission to recipients, some of whom could be incubating the disease. In the absence of a large-scale screening test, it is impossible to establish the prevalence of infection in the blood donor population and transfused patients. This lack of a test also prevents specific screening of blood donations. Thus, prevention of transfusion transmission essentially relies at present on deferral of "at-risk" individuals. Because prions are present in both white blood cells and plasma, leukoreduction is probably insufficient to totally eliminate the transfusion risk. In the absence of a screening test for blood donations, recently developed prion-specific filters could be a solution. Furthermore, while the dietary spread of vCJD seems efficiently controlled, uncertainty remains as to the extent of the spread of prions through blood transfusion and other secondary routes.

    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.

    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.

    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.

    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.

    2016-08-01

    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.

    Most of the models of proton SEUs predictions use the sensitive volume concept. The sensitive region is modeled by a parallelepiped with length l, width w and thickness d, buried at depth h. We propose a new method to extract the sensitive thickness d. The idea is to use low energy, low range ion in order to probe the component to measure the sensitive volume. The thickness d is obtained by de-convoluting the heavy ion upset cross-section curve with the LET (linear energy transfer) curve, both curves being considered as functions of the range of the incident ion. This method has been tested using a beam of carbon ions and the calculated thickness is closed to the theoretical expected value. The deconvolution method which couples together a sensitive thickness d and a charge collection efficiency {alpha} improves the sensitive volume concept.

    LHCb sensitivity to a standard model Higgs in the H + (W, Z) → bb-bar + (ll-bar, νll) channel has been studied. Different effects affecting jet reconstruction have been studied at generator and full simulation of the detector level. After correction di-b-jet, mass resolution is σm/mmoyen = 22%. b-jet identification procedure has been set up, selecting ∼ 80% of b-jets while rejecting ∼ 99.5% of other jets. After reducing the bb-bar + l physical background, a statistical significance of 1 is obtained for 4 years of data taking at a luminosity of 5.1032cm-2s-1. (author)

    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. PMID:20980120

  6. Determination of the adaptive response induced In vivo by gamma radiation and its relation with the sensibility to the damage induction in the DNA and with the repairing capacity

    International Nuclear Information System (INIS)

    The kinetics of damage induction and repair at different doses as well as the adaptive response induced by gamma ray exposure were determined in murine leukocytes in vivo. The damage-repair kinetics were established after the exposure to 0.5, 1.0 or 2.0 Gy in a 137Cs source. Peripheral blood samples were obtained from the tails of mice, the percentage of damaged cells and the DNA migration in each one were analyzed by the single cell gel electrophoresis (SCG) technique or comet assay. Results indicated that there was an induction of approximately 75% comets with the doses of 1.0 and 2.0 Gy, which was considerably reduced to 22% and 42% respectively during the first 15 minutes. This evidences the presence of a rapid repair process and suggests that leucocytes are genetically well prepared to repair this kind of damage. After 15 minutes, a second increase in the percentage of damaged cells that was proportional to dose occurred, which seems to represent the breaks produced during the repair of other kind of lesions. After that a second reduction was observed, reaching values near to the basal ones, except with the dose of 2.0 Gy. The kinetics obtained with the dose of 0.5 Gy was similar to that established with 1.0 Gy, but in this case the initial damage was 50 % lower. Besides, the adaptive response was observed after the exposure of the mice to an adaptive dose of 0.01 Gy and to a challenge dose of 1.0 Gy 60 minutes later. The pretreatment reduced the percentage of damaged cells caused by the challenge dose to one third approximately, and also diminished this parameter produced during the late repair process. This indicates that the early adaptive response is caused, instead of by an increment in repair, by the induction of a process that protects DNA from damage induction by radiation, i.e synthesis of substances that increase the scavenging of free radicals.

    The present paper describes the details and current situation of the above cable developed for detecting external damages caused by an anchor of a ship or the like. An investigation for the purpose of solving the defects of conventional metallic type sensing line has been conducted and reached a conclusion that the adoption of optical fiber can accomplish the purpose. The optical fiber is characterized by the facts that an external force causes transmission loss and repeated hooking of anchors is allowed. In addition, a sensing system was combined with the optical fiber to attain the purpose. The optical fiber unit to be used in a submarine cable must comprise two other kinds of optical fibers for cable temperature measurement and for instrument control and communication between substations. It was the greatest problem in the above development to find out a unit structure satisfying all of these requirements. Good results were obtained in the tests of the optical fiber of adopted structure for temperature characteristics, stability under pressurized water, mechanical characteristics such as tensile strength etc. and prevention of water running. Submarine-use CV cables which are of three-core type and armored with double steel wires were adopted after considering their capacity and protection method and their performances were confirmed in various tests. 6 figs.

    欧里庇得斯的剧作标志着古希腊悲剧对"人"这一命题探索重心的向内转移.他通过将笔触深入到美狄亚等人物的内心世界,试图揭示--真正造成人类悲剧的根源并不是那冥冥之中不可知的命运之神在作祟,而恰恰是人类自身那难以遏止的私欲在作祟;在膨胀的私欲面前,"情与理"都可能产生极度的扭曲变形而走向反面.

    Objective: To investigate the sensitivity of the Fluctuation test and Ames test for mutagenicity of quercetin. Methods: Salmonella typhimurium histidine auxotrophs TA98 and TA100 were chosen as the test strains in this study and the Ames test was conducted by using the plate incorporation method. Varied concentrations of Quercetin (3.2, 16, 80, 400 and 2000 μg/mL) were applied with or without Aroclor-induced rat liver S9-activation for 48h. The fluctuation test was conducted with 96-well plate. In the non-activated or S9 activated 24-hour exposure group, bacterial were exposed to quercetin with concentrations of 0.128, 0.64, 3.2, 16 and 8 μg/mL. And the positive wells were counted. Results: The mean number of revertants in Salmonella strains treated with quercetin at 80, 400 and 2000μg/mL increased at least two-fold greater than that in the vehicle control by performing the Ames assay and which was dose dependent. Moreover, the number of positive wells/plate increased in a dose dependent manner when treated with quercetin mentioned above (P<0.01). With the Fluctuation test, the results showed positive with the dose of quercetin in the range of 0.64-16μg/mL, but not in Ames test. Conclusion: In the low concentration of quercetin, the positive results were detected by the Fluctuation test but not in the Ames test, which implied that the fluctuation test has higher sensitivity than Ames test in mutagenicity assay of quercetin.%目的:通过传统Ames试验与改进彷徨试验对槲皮素的致突变试验结果,比较两种试验的灵敏度.方法:Ames试验方法采用平板掺入法,选择3.2、16、80、400、2000μg/mL 5个剂量组的槲皮素在有或无代谢话化条件下处理鼠伤寒沙门氏菌株TA98和TA 100 48小时后计数回复突变菌落数;改进彷徨试验采用96孔板法,选择0.128、0.64、3.2、16、80μg/mL 5个剂量组的槲皮素在有或无代谢活化条件下处理鼠伤寒沙门氏菌株TA98和TA100 24小时后计数变色孔数.结果:Ames试验结果显示槲皮素在80-2000μg/mL回复突变菌落数明显增加并超过对照2倍并有明显剂量反应关系,Ames试验结果阳性;改进彷徨试验结果显示槲皮素在0.64-80μg/mL变色孔数明显增加(P<0.01),并有剂量反应关系,结果为阳性;而在0.64-16μg/mL剂量下,改进彷徨试验能检测出阳性结果,而Ames试验未检测出阳性结果.结论:在较低浓度时,改进彷徨试验能检测出Ames试验检测不出的阳性结果,表明改进彷徨试验灵敏度较Ames试验高.

    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)

    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)

    Full Text Available This essay centers its analysis in the disagreement about the image of the thought between Rancière and Deleuze to approach the contemporary relationship between esthetics and politics. The philosophical problem in which is sustained the debate is the quarrel about the relationships of immanence and singularity that articulate for Deleuze its own image of the thought, while Rancière considers this notions as an abandonment of the principles of utopia and emancipation destined to the integration of the anonymous in the distribution of the sensitive. The problems in this debate is focused in a program that crosses philosophy and literature, where Bartleby, the scrivener of Herman Melville acquires relevancy.

    Full Text Available There is growing interest and importance in addressing the logistical and ethical challenges of conducting research with disenfranchised populations, including homeless and working street youth. Drawing upon established international standards on human rights, we review legal and ethical codes for research on disenfranchised populations established by national and international research and professional organizations. Then we explore how university-based researchers can apply these standards to children and adolescents growing up in situations characterized by physical and psycho- logical neglect, lack of adult supervision, limited protection from local law enforcement, and drug use and violence. We reflect upon on our experi- ences in conducting research with vulnerable Brazilian youth to illustrate the challenges of implementing ethical guidelines in real-world situations and propose possible solutions to ethical dilemmas encountered in the field.

Con 83 modelos reconstruidos de aneurismas cerebrales se hizo un estudio geométrico y se seleccionó un caso para estudiar la fluido dinámica en detalle. Se varió el número de sifones carotideos usados para la simulación CFD. Se realizaron cinco simulaciones FSI variando el modulo de elasticidad arterial y el espesor arterial, y se reportó el efecto de la hipertensión arterial en los resultados. Las simulaciones FSI mostraron que el efecto más relevante en el incremento del estado de esfuerzos en la aneurisma es la hipertensión arterial, con esfuerzos máximos cercanos a 900 kPa. Se concluye que las simulaciones FSI se deben usar para determinar simultáneamente el estado de esfuerzos de la pared y la fluido dinámica dentro de aneurismas.A sensitivity study of the results provided by computational fluid dynamics (CFD in models of cerebral aneurysms including fluid structure interaction (FSI was performed. With 83 reconstructed models of cerebral aneurysms, a geometrical study was done and one case was selected for a detailed study of the computational fluid dynamics. In this model the number of carotid siphon used for the CFD simulations was varied. In the FSI study, five simulations were conducted varying the elastic modulus of the artery and the arterial wall thickness, and the effect of hypertension on the results was reported. The FSI simulations have shown that the most important parameter that affeets the aneurysm wall stress state is the arterial hypertension with máximum stress of around 900 kPa. It is concluded that FSI simulations must be used to simultaneously determine the wall stress and the fluid dynamics inside cerebral aneurysm.

    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.

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.

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...

    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.

    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.

    This paper investigates the capability of Kinect sensor as interactive technology and discusses how it can assist and improve teaching and learning. The Kinect sensor is a motion sensor that provides a natural user interface. It was implemented by Microsoft for the Xbox 360 video-game console to create a new control-free experience for the user without any intermediary device. The Kinect sensor can enhance kinesthetic pedagogical practices to profit learners with strong bodily-kinesthetic int...
