  1. Sense and clinical sensibility.

    PubMed

    Billow, Richard M

    2013-10-01

    I call attention to the metapsychology of sense, and the role sense plays-phenomenologically and symbolically-in the life of the clinician and the group. Each group member asserts influence in taking a role as the perceiver and the perceived, the senser and the sensed. We reach for sense, for without sense reference, we cannot grasp or even talk about psychic reality. It serves as sign and symbol, as metaphor, analogy, illustration, and model. Sense fixes experience yet may fixate experience and interfere with developing abstract thoughts. Clinical vignettes illustrate how the leader may utilize his or her particular clinical sensibility to reach the group and focus attention, to link sense to psychic qualities: to the personality of the members, the group culture and process, and the live clinical interaction.

    2012-01-01

    The author tries to argue how epistemic sensibility as virtue sensibility can complement virtue epistemology. Many philosophers interrelated virtue reliabilism (e.g., Brogaard, 2006) and virtue responsibilism (e.g., Code, 1987) to virtue epistemology as two dimensions with many diverging and a few converging characters. The possible new dimension…

    Changes in breast sensibility after reduction mammaplasty remain a controversial subject and most previous studies report only qualitative results. There is more accurate measuring of the sensibility of the skin with the Pressure-Specified Sensory Device (PSSD), which measures the pressure perception of the skin in grams per square millimeter. The evaluation of breast sensibility before and after reduction mammaplasty using the upper medial pedicle technique was undertaken in 25 patients. The PSSD was used to measure one dynamic point threshold in nine points of the breast during the preoperative period and 6 months after surgery. After surgery all patients had decreased sensation in all points studied, and this was significant. There are few reports of breast sensibility after mammaplasty using the PSSD, and the discrepancy in results reported using other methods of evaluation could be related to precision in evaluation.

  11. Evaluation of cutaneous abdominal wall sensibility after abdominoplasty.

    PubMed

    2005-01-01

    Changes in cutaneous sensibility are common after diverse plastic surgical procedures. Although prior studies examined aesthetic results, combined procedures, and new abdominoplasty techniques, few examined the effect of undermining on cutaneous sensibility. This study aimed to analyze and quantify cutaneous sensibility after classic abdominoplasty. Two groups of patients were studied: a control group of 10 patients without surgery and another group of 25 patients who had undergone classic abdominoplasty. The abdominal wall surface was divided into nine regions. Pain sensibility was evaluated by tests with needles, and thermal sensibility by test tubes containing hot and cold water. Superficial tactile sensibility was tested using the Pressure-Specified Sensory Device (PSSD), which is capable of determining the cutaneous pressure threshold. Statistical analysis was conducted using Student's 't-test'. The results showed a decrease in the three types of sensibility. Statistical analysis showed a significant difference (p < 0.05) between the groups for all regions tested. The centermost regions of the abdominal wall presented the highest index of analgesia and thermal anesthesia, as well as higher cutaneous pressure thresholds. PMID:15759089

  13. Sensible heat receiver for solar dynamic space power system

    NASA Technical Reports Server (NTRS)

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

    1991-01-01

    A sensible heat receiver considered in this study uses a vapor grown carbon fiber-carbon (VGCF/C) composite as the thermal storage media and was designed for a 7 kW Brayton engine. The proposed 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.

    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.

    Introducción El tejido adiposo blanco (TAB) subcutáneo (Sc) humano podría variar dependiendo de su localización anatómica, con diferencias en su perfil proteómico. Pacientes y métodos Se obtuvieron aspirados de TAB-Sc de seis mujeres con IMC >25 kg/m2, sometidas a liposucción. Dicho TAB-Sc se obtuvo de seis localizaciones anatómicas: abdominal superior e inferior, muslo, dorsal, flanco y cadera, analizándose su perfil proteómico mediante electroforesis bidimensional. En muslo y abdomen superior se compararon, además, las muestras obtenidas de las dos capas del TAB-Sc (profunda y superficial). Resultados Se detectaron 21 proteínas que mostraban una intensidad de expresión diferente entre las seis localizaciones anatómicas y 14 entre las capas superficial y profunda de una misma región. Entre las proteínas identificadas se incluyen: vimentina (proteína estructural); proteínas “heat-shock” (HSPs), superóxido-dismutasa, (estrés/chaperoninas); proteína fijadora de ácidos grasos 4 (FABP-4) y alfa-enolasa (metabolismo lipídico y de los hidratos de carbono, respectivamente) y ATP-sintetasa (producción de energía). Entre las regiones estudiadas, el TAB-Sc dorsal mostraba un perfil proteómico particular, con menor expresión de proteínas implicadas en la producción de energía y metabolismo (ATP-sintetasa, alfa-enolasa, HSPs y FABP-4) que el resto de regiones. Conclusiones Los niveles de expresión de diversas proteínas en el TAB-Sc humano no son homogéneos, difiriendo entre localizaciones anatómicas. Esto sugiere la existencia de diferencias funcionales en el TAB-Sc de acuerdo con su localización anatómica, lo que debe considerarse antes de asumir la extrapolación de los datos derivados del TAB-Sc de una determinada localización al de otras partes de la anatomía.

  19. Sensible Quantum Mechanics:. are Probabilities Only in the Mind?

    NASA Astrophysics Data System (ADS)

    Page, Don N.

    Quantum mechanics may be formulated as Sensible Quantum Mechanics (SQM) so that it contains nothing probabilistic except conscious perceptions. Sets of these perceptions can be deterministically realized with measures given by expectation values of positive-operator-valued awareness operators. Ratios of the measures for these sets of perceptions can be interpreted as frequency-type probabilities for many actually existing sets. These probabilities generally cannot be given by the ordinary quantum “probabilities” for a single set of alternatives. Probabilism, or ascribing probabilities to unconscious aspects of the world, may be seen to be an aesthemamorphic myth.

  20. Rainfall droplet size distributions (DSD) parameterization: physics and sensibility

    2014-12-01

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

    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.

    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.

  12. A Three Component Model to Estimate Sensible Heat Flux Over Sparse Shrubs in Nevada

    Chehbouni, A.; Nichols, W.D.; Njoku, E.G.; Qi, J.; Kerr, Y.H.; Cabot, F.

    1997-01-01

    It is now recognized that accurate partitioning of available energy into sensible and latent heat flux is crucial to understanding surface-atmosphere interactions. This issue is more complicated in arid and semi-arid regions where the relative contribution to surface fluxes from the soil and vegetation may vary significantly throughout the day and throughout the season. The objective of this paper is to present a three-component model to estimate sensible heat flux over heterogeneous surfaces. The surface was represented with two adjacent compartments. The first compartment is made up of two components, shrubs and shaded soil; the second compartment consists of bare, unshaded soil. Data collected at two different sites in Nevada during the summers of 1991 and 1992 were used to evaluate model performance. The results show that the present model is sufficiently general to yield satisfactory results for both sites.

    In recent years the sensibility of CR-39 to nuclear tracks has been increased by doping the corresponding monomer with dioctyl phtalate. At this regard, two theoretical approaches are current managed to explain this phenomenon: either the doping react with the active radicals in the chain blocking them, stopping crosslinking between chains, or alternatively that the doping gets between them giving wider space between the crosslinkined chains.

    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.

  16. Evaluation of the profile and the resistance method for estimation of surface fluxes of momentum, sensible and latent heat

    1992-06-01

    Hourly lysimetric and micrometeorological data taken over a grass surface at the Meteorological Research Unit, Cardington U.K. have been analysed. A temperature difference and measurements of wind speed at only one height, combined with an independently estimated effective roughness length allowed sensible heat and momentum fluxes determination by the profile method on an hourly basis. The estimates are compared with direct measurements of sensible heat and friction velocity obtained by the eddy correlation method. The sensible and latent heat fluxes are also modelled by the resistance method. Equations based on the Monin—Obukhov similarity theory are used to account for stability effects through various forms of parameterization Aerodynamic and surface resistances, necessary for the Penman—Monteith equation are calculated from routinely measured meteorological data. The profile method for estimation of sensible heat flux and friction velocity is found to work excellently on the discussed daytime experimental data which correspond mainly to near neutral or slightly unstable conditions. Surface latent and sensible heat fluxes can also be described very well by the resistance method. A slightly better estimate of the sensible heat flux is achieved when stability corrections are taken into account. On the contrary Penman-Monteith equation for estimating latent heat flux is insensitive to adjustments for atmospheric stability. The comparison of the various methods leads to the establishment of empirical relationships which correlate various quantities such as soil heat flux, resistances, evapotranspiration etc. to routinely measured meteorological data.

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

    2011-04-01

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

    An evaluation of convective boundary layer budgets of sensible heat and moisture were examined for two days over the unstressed vegetation of the tallgrass Konza National Prairie. In addition to the budget evaluation the study had these goals: to estimate the area-average surface fluxes and compare them to independent, ground-based measurements, to estimate the near surface evaporative fraction, and to compare different evaluations of the ratio of surface to inversion fluxes, i.e., the entrainment parameter. The budget analyses indicate that vertical and horizontal advection were significant terms in the budget and cannot be ignored.

  20. Tubular cross talk in acute kidney injury: a story of sense and sensibility.

    The mammalian kidney is an organ composed of numerous functional units or nephrons. Beyond the filtering glomerulus of each nephron, various tubular segments with distinct populations of epithelial cells sequentially span the kidney from cortex to medulla. The highly organized folding of the tubules results in a spatial distribution that allows intimate contact between various tubular subsegments. This unique arrangement can promote a newly recognized type of horizontal epithelial-to-epithelial cross talk. In this review, we discuss the importance of this tubular cross talk in shaping the response of the kidney to acute injury in a sense and sensibility model. We propose that injury-resistant tubules such as S1 proximal segments and thick ascending limbs (TAL) can act as "sensors" and thus modulate the responsiveness or "sensibility" of the S2-S3 proximal segments to injury. We also discuss new findings that highlight the importance of tubular cross talk in regulating homeostasis and inflammation not only in the kidney, but also systemically. PMID:25877507

    The thermal environment in the plant canopy affects plants' growth processes such as flowering and ripening. High temperatures often cause grain sterility and poor filling, and reduce crop production in tropical and temperate regions. With global warming predicted, these effects have become a major concern worldwide. In this study, surface renewal analysis, which is a novel method for estimating scalar fluxes, was applied to rice, maize and soybean canopies to understand the dynamics of sensible heat in crop canopies. Surface renewal analysis has advantages of (1) lower cost of equipment, (2) a shorter fetch requirement and (3) less disturbance in the field. The temperature of the atmosphere (T) at multiple heights was measured at 10 Hz with fine-wire thermocouples to calculate sensible heat flux (H) from the ramp pattern of T. Variations in H determined from the T measurements at canopy top was from -80 to 120 Wm-2 for rice, and it showed reasonable diurnal variation. However, H values determined from the T measurements within the canopies were smaller because of differences in temperature ramp frequency with height. These results suggest that not all turbulent structures penetrate deeply into canopies. The results for rice, maize and soybean canopies will be presented at the meeting.

    Scintillometers have been widely used in estimating the surface-layer sensible heat flux (Q_H) over natural and urban surfaces, but their application over water bodies is rare. Here, a large aperture scintillometer (LAS) was deployed over a coastal maritime area (`a beach') with an optical path distance of 1 km to investigate LAS capability in estimating the sensible heat fluxes. The measurements were conducted for clear days in the cold season, characterized by a warmer sea surface than the overlying air throughout the studied days. The LAS-derived Q_H showed a significant diurnal variability of 10-150 W m^{-2} at the coastal site, and it was found that local thermal advection and tidal change at the site largely influenced the diurnal variability. A series of sensitivity tests indicated that the uncertainty in the LAS-derived Q_H was less than 11 %, except when De Bruin's similarity function was used. The overall results demonstrate that the LAS system can detect the magnitude and variability of the turbulent heat exchange at the coastal site with high temporal resolution, suggesting its usefulness for estimating Q_H in the coastal maritime environment.

  3. An analysis of turbulent sensible heat fluxes within a heterogeneous black spruce boreal forest in Alaska

    NASA Astrophysics Data System (ADS)

    Starkenburg, Derek

    Turbulent sensible heat fluxes within the heterogeneous canopy of a black spruce boreal forest in Interior Alaska are evaluated at three different scales in order to assess their spatial variability, and to determine the feasibility of upscaling locally measured flux values to the landscape scale for modeling applications and climate studies. The first evaluation is performed locally at a single micrometeorological tower in an area of the boreal forest with a mean canopy height of 4.7 m. The data were taken across winter, spring and summer of 2012 from two sonic anemometers, one below the canopy at 3 m above ground, and one above the canopy at 12 m above ground. A multiresolution analysis is used to isolate coherent structures from the turbulent temperature time series at both instruments. When mean global statistics of coherent structures are analyzed at the two levels independently, results show an average of 8 structures per period, a mean duration of 85 s, and a mean sensible heat flux contribution of 48%. A spectral version of the Stokes parameters is applied to the turbulent horizontal wind components to show that 31% of the coherent turbulent structures detected at 12 m, and 13% at 3 m, may be complicated by canopy waves due to the prevalence of stable flows at this high latitude location. The second evaluation quantifies differences in turbulent sensible heat fluxes horizontally between two micrometeorological towers 600 m apart, one in a denser canopy (DC) and the other in a sparser canopy (SC), but under approximately similar atmospheric boundary layer conditions. Results show that SC is ˜ 3 °C cooler and more stably stratified than DC during nighttime. This suggests that changes in the height and density of the canopy impact local temperature and stability regimes. Most importantly, the sensible heat flux at DC is greater during midday periods, with that difference exceeding 30% of the measured flux and over 30 W m-2 in magnitude more than 60% of the time. The third evaluation compares locally measured sensible heat fluxes from a sonic anemometer atop a 24 m micrometeorological tower to those derived from a large aperture scintillometer (LAS) whose beam is centered near the tower at an average height of 36 m above ground, and over a path length of 1423 m. This analysis focuses on unstable daytime periods from June, July and August of 2013. The daytime is defined as 0700-2000 Alaska Standard Time, since local sensible heat flux values derived from the sonic anemometer (H EC) are robust (above 50 W m-2) during this time, and since this time also agrees with the minima in the mean diurnal pattern of Cn2 from the LAS. For daytime periods with robust sensible heat flux values, HEC and the large-scale flux from the LAS (HLAS) correlate with R2 = 0.68, while H EC captures about 82% of HLAS on average. The magnitude of HEC and HLAS are both strongly sensitive to incoming solar radiation, with HLAS having a better correlation and regression slope, suggesting that the local measurements are adjusting also to surface and/or flow conditions above the heterogeneous canopy. Evaluation of the magnitude of the ratio of HEC/HLAS for days with varying amounts of solar radiation suggests that while radiation affects the magnitude of HEC and HLAS independently, it does not affect their ratio. For daytime periods with lower fluxes (HEC between 10 and 50 W m-2), HEC captures about 69% of HLAS on average. However, local and large-scale fluxes during this low flux regime correlate poorly with incoming solar radiation (R2 = 0.42 for HLAS and R2 = 0.15 for HEC), and with one another (R2 = 0.27), suggesting that local heterogeneities are not well-integrated into the large-scale flux. Therefore, low flux periods should be considered separately for the purposes of upscaling local to landscape scale flux values in the boreal forest. For the high flux regime, a finer resolution of upscaling can be provided based on the mean diurnal pattern of HEC/HLAS and the Obukhov length (L). Namely, as the boundary layer becomes less unstable in late

    The primary aim of this paper was to present the results of turbulent sensible heat flux (QH) measurements with Scintillometer Scintec BLS900 (LAS). The theoretical background of scintillation method has been presented as well as two different ways of sensible heat flux computation from LAS. The measurements presented here were conducted from April to December 2011. Diurnal and partially annual variability of QH has been analyzed, moreover the mean diurnal course of QH in considered months has been prepared. In order to choose the optimal method of QH computation from LAS the results obtained with three different Monin-Obuchov similarity theory functions as well as free convection assumption has been compared. In first case it has been proved that sensible heat flux differs significantly depending on chosen universal function. In turn in case of free convection assumptions it has been revealed that it is valid only for very unstable conditions. Therefore it does not apply to long-time heat flux measurement in case of ?ód?. Nevertheless, this study has shown that scintillation method is valuable and reasonable source of path-averaged QH estimates in considered city.

    The nature of the Barrow Coastal Polynya (BCP) formed off the Alaska Coast in winter is examined using mooring data (temperature, salinity, and ocean current), atmospheric re-analysis data (ERA-Interim), and AMSR-E-derived sea-ice concentration and production data (Iwamoto et al., 2014). Previously, the BCP has been considered to be a latent heat polynya formed by predominantly offshore winds resulting in sea-ice divergence. Recently, it has been suggested that the sea-ice production rate in the BCP is suppressed by warm Pacific- or Atlantic-origin waters distributed beneath the BCP (e.g. Itoh et al., 2012). In this study, we focus on the oceanographic conditions such as water mass distribution and ocean current structure beneath the BCP, which have not been fully documented. A mooring was deployed off Barrow, Alaska in the northeast Chukchi Sea (71.23°N, 157.65°W, water depth 55 m) from August 2009 to July 2010. During the freeze-up period from December to May, five BCP events occurred in the same manner; 1) dominant wind parallel to Barrow Canyon, with an offshore component near Barrow, 2) high sea-ice production followed by sudden cessation of ice growth, 3) upwelling of warm (>2 K above freezing point) and saline (>34) Atlantic Water (AW) beneath the BCP, 4) strong up-canyon flow (>100cm/s) associated with density fluctuations. A baroclinic current structure, established after the upwelling, resulted in enhanced vertical shear, promoting vertical mixing. The mixing event and open water formation occurred simultaneously, once sea-ice production had stopped. Thus, mixing events accompanied by ocean heat flux from AW into the surface layer were likely to form/maintain the open water area that is a sensible heat polynya. The transition from a latent to a sensible heat polynya was well reproduced by a pan-Arctic ice-ocean model (COCO). We propose that the BCP is a hybrid latent and sensible heat polynya, with both processes driven by the same offshore wind.

    The high- and low-latitude radiative-dynamic (HLRD) climatic model of Wang et al. (1984) was used to study the effect of meridional heat (MH) fluxes on climate changes caused by increases of CO2 abundance and solar constant variations. However, the empirical MH parameterization of the HLRD model was replaced by physically based parameterization, which gives separate meridional sensible and latent heat fluxes and provides a complete representation of the dependence of the flux on the mean temperature field. Both parameterization methods yielded about the same changes in global mean surface temperature and ice line, and both produced only small changes in meridional temperature gradient, although the latter were even smaller with the physically based parameterizations. At any latitude, the hemispheric mean surface temperature, rather than MH fluxes, dominates the surface temperature changes.

    2015-08-01

    Scintillometer measurements of turbulent fluxes of momentum and sensible heat in the roughness sublayer over a regular array of cubes in an outdoor environment were tested with direct measurement from sonic anemometers. The dissipation rate, ?, and temperature structure parameter, C T 2 , obtained from the scintillometer agreed well with those from four sonic anemometers located along the scintillometer path. The fluxes measured by the scintillometer also corresponded well to those from the line-averaged eddy covariance approach, although this agreement was greatly influenced by the choice of the zero-plane displacement length and the form of the similarity function used in the scintillometer software. A guide for choosing the appropriate similarity function for the urban roughness sublayer is proposed.

    1990-01-01

    A Charney-Branscome based parameterization has been tested as a way of representing the eddy sensible heat transports missing in a zonally averaged dynamic model (ZADM) of the atmosphere. The ZADM used is a zonally averaged version of a general circulation model (GCM). The parameterized transports in the ZADM are gaged against the corresponding fluxes explicitly simulated in the GCM, using the same zonally averaged boundary conditions in both models. The Charney-Branscome approach neglects stationary eddies and transient barotropic disturbances and relies on a set of simplifying assumptions, including the linear appoximation, to describe growing transient baroclinic eddies. Nevertheless, fairly satisfactory results are obtained when the parameterization is performed interactively with the model. Compared with noninteractive tests, a very efficient restoring feedback effect between the modeled zonal-mean climate and the parameterized meridional eddy transport is identified.

    INTRODUCTION The prudent selection of surgical gloves can deliver significant efficiency savings. However, objective data are lacking to compare differences in cutaneous sensibility between competing gloves. Therefore, the present study examined the use of a single comparable model of sterile surgical glove from two competing providers, Gammex PF HyGrip® (Ansell Limited, Red Bank, NJ, USA) with Biogel® (Mölnlycke Health Care AB, Göteborg, Sweden). SUBJECTS AND METHODS Cutaneous pressure threshold, static and moving two-point discrimination were measured as indices of objective surgical glove performance in 52 blinded healthcare professionals. RESULTS The mean cutaneous pressure threshold was 0.0680 ± 0.0923 g for skin, 0.411 ± 0.661 g for Ansell gloves and 0.472 ± 0.768 g for Biogel gloves. Skin was significantly more sensitive than Ansell (P< 0.0001) or Biogel (P< 0.0001) gloves (Wilcoxon signed rank test). There was no statistical difference between Biogel and Ansell gloves (P = 0.359). There was no significant difference between static or moving 2-point discrimination of skin and Ansell gloves (P= 0.556, P = 0.617; Wilcoxon signed rank test), skin and Biogel gloves (P= 0.486, P= 0.437; Wilcoxon signed rank test) or Ansell and Biogel gloves (P= 0.843, P= 0.670; Wilcoxon signed rank test). CONCLUSIONS No demonstrable objective difference was found between competing gloves in the outcome measures of cutaneous sensibility and two-point discrimination. However, a difference in subjective preference was noted. Untested factors may underlie this discrepancy, and further research should employ more sophisticated measurements of surgical performance using competing models of surgical glove. PMID:21118618

  10. Sensible method for updating motif instances in an increased biological network.

    A network motif is defined as an over-represented subgraph pattern in a network. Network motif based techniques have been widely applied in analyses of biological networks such as transcription regulation networks (TRNs), protein-protein interaction networks (PPIs), and metabolic networks. The detection of network motifs involves the computationally expensive enumeration of subgraphs, NP-complete graph isomorphism testing, and significance testing through the generation of many random graphs to determine the statistical uniqueness of a given subgraph. These computational obstacles make network motif analysis unfeasible for many real-world applications. We observe that the fast growth of biotechnology has led to the rapid accretion of molecules (vertices) and interactions (edges) to existing biological network databases. Even with a small percentage of additions, revised networks can have a large number of differing motif instances. Currently, no existing algorithms recalculate motif instances in 'updated' networks in a practical manner. In this paper, we introduce a sensible method for efficiently recalculating motif instances by performing motif enumeration from only updated vertices and edges. Preliminary experimental results indicate that our method greatly reduces computational time by eliminating the repeated enumeration of overlapped subgraph instances detected in earlier versions of the network. The software program implementing this algorithm, defined as SUNMI (Sensible Update of Network Motif Instances), is currently a stand-alone java program and we plan to upgrade it as a web-interactive program that will be available through http://faculty.washington.edu/kimw6/research.htm in near future. Meanwhile it is recommended to contact authors to obtain the stand-alone SUNMI program. PMID:25869675

    This was an initial exploratory study to determine if decompression of the 4 medial ankle tunnels (neurolysis of the tibial, medial and lateral plantar, and calcaneal nerves) could lead to improved foot sensibility, increased proprioception and balance, and decreased falls in a population of patients with impaired lower extremity sensation. Fourteen patients with peripheral neuropathy were included in this study. Seventy-one percent of patients were females. Average age was 67 years. All patients were evaluated preoperatively and postoperatively to assess their lower extremity sensibility, as well as their ability to stand still, maintaining their balance with their eyes open and then closed, which is defined as "sway." Lower extremity sensibility was measured with the Pressure-Specified Sensory Device (PSSD), which evaluates 1- and 2-point discrimination for the pulp of the big toe and medial heel. The MatScan Measurement System measured each patient's sway. Neuropathy was the result of diabetes in 72% of patients, a combination of diabetes and hypothyroidism in 7%, chemotherapy in 7%, and idiopathic in 14%. Eight patients underwent peripheral nerve decompression on 1 lower extremity, whereas 6 patients underwent bilateral lower extremity peripheral nerve decompression. Mean toe and heel sensibility improved 9% and 7%, respectively, in the unilateral group, whereas the bilateral group experienced an improvement in mean toe and heel sensibility of 42% (P = 0.02) and 32%, respectively. Preoperative and postoperative sway comparison in the unilateral group revealed a reduction in sway with eyes open and eyes closed by 5% and 31%, respectively. Comparison of preoperative and postoperative sway in the bilateral group showed a reduction with eyes open and eyes closed by 23% and 145% (P = 0.05), respectively. This initial study suggests that there may be benefit from bilateral lower extremity peripheral nerve decompression in helping improve pedal sensibility and balance within the peripheral neuropathy patient population, although further investigation with a larger sample size is warranted to further evaluate these preliminary findings.

  15. Responses of sensible heat flux to soil water variation over a forest in a subalpine mountain valley

    Sensible heat flux is a vital component of Evapotranspiration (ET) and a critical process in the energy budget of the earth-atmosphere system. In our early study, it's found that soil water variation may be a critical factor for sensible heat flux over the forest in a subalpine mountain valley. The components of surface energy fluxes were measured for 2 years using the eddy covariance technique in Jiuzhaigou Valley, a subalpine mountainous area of Southwest China. Meanwhile, transpiration was measured by sap flow sensors. Within the observation period, the magnitude and distribution of energy fluxes and the magnitude of transpiration were mainly controlled by leaf emergence and seasonal changes in net radiation and soil water content. Large increases in transpiration were observed after leaves emerged around May, while evapotranspiration started to increase from February, which increased from nearly zero during winter to more than 5 mm d-1 in summer. Large increases in soil water content were observed despite increases in evapotranspiration during early spring. In spite of the large increases in net radiation, obvious decreases in sensible heat flux were observed with the variation of soil water content over the same period. Therefore, the most influential effect on the variability of sensible heat flux was the soil water content. These general characteristics can help us have a better understanding of the energy budget and water consumption of forest and their responses to net radiation and soil water content.

    Surface temperatures, Ts, were estimated for a natural vegetative surface in Owens Valley, California, with infrared thermometric observations collected from an aircraft. The region is quite arid and is composed primarily of bushes (???30%) and bare soil (???70%). Application of the bulk transfer equation for the estimation of sensible heat, H, gave unsatisfactory values when compared to Bowen ratio and eddy correlation methods over a particular site. This was attributed to the inability with existing data to properly evaluate the resistance to heat transfer, rah. To obtain appropriate rah-values the added resistance to heat transfer, kB-1, was allowed to vary although there is both theoretical and experimental evidence that kB-1 for vegetative surfaces can be treated as constant. The present data indicate that for partial canopy cover under arid conditions kB-1 may be a function of Ts measured radiometrically. The equation determining kB-1 was simplified and tested over another arid site with good results; however, this had a limited data set (i.e., 6 data points). The dimensionless kB-1 equation is simplified for use over full canopy cover and is shown to give satisfactory estimates of H over a fully-grown wheat crop. ?? 1989.

  17. From Sensibility to Pathology: The Origins of the Idea of Nervous Music around 1800

    PubMed Central

    KENNAWAY, JAMES

    2014-01-01

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

    The 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.

    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.

    Surface renewal (SR) analysis is an interesting alternative to eddy covariance (EC) flux measurements. We have applied two recent SR approaches, with different theoretical background, that from Castellví (2004), SRCas, and that from Shapland et al. (2012a,b), SRShap. We have applied both models for sensible (H) and latent (LE) heat flux estimation over heterogeneous crop surfaces. For this, EC equipments, including a sonic anemometer CSAT3 and a krypton hygrometer KH20, were located in two zones of drip irrigated orchards of late and early maturing peaches. The measurement period was June-September 2009. The SRCas is based on similarity concepts for independent estimation of the calibration factor (?), which varies with respect to the atmospheric stability. The SRShap is based on analysis of different ramp dimensions, separating the ones that are flux-bearing from the others that are isotropic. According to the results obtained here, there was a high agreement between the 30-min turbulent fluxes independently derived by EC and SRCas. The SRShap agreement with EC was slightly lower. Estimation of fluxes determined by SRCas resulted in higher values (around 11% for LE) with respect to EC, similarly to previously published works over homogeneous canopies. In terms of evapotranspiration, the root mean square error (RMSE) between EC and SR was only 0.07 mm h-1 (for SRCas) and 0.11 mm h-1 (for SRShap) for both measuring spots. According to the energy balance closure, the SRCas method was as reliable as the EC in estimating the turbulent fluxes related to irrigated agriculture and watershed distribution management, even when applied in heterogeneous cropping systems.

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

    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?

    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. PMID:24473285

    SummaryLittle is known of energy balance in low latitude wetlands where there is a year-round growing season and a climate best defined by wet and dry seasons. The Florida Everglades is a highly managed and extensive subtropical wetland that exerts a substantial influence on the hydrology and climate of the south Florida region. However, the effects of seasonality and active water management on energy balance in the Everglades ecosystem are poorly understood. An eddy covariance and micrometeorological tower was established in a short-hydroperiod Everglades marsh to examine the dominant environmental controls on sensible heat ( H) and latent energy ( LE) fluxes, as well as the effects of seasonality on these parameters. Seasonality differentially affected H and LE fluxes in this marsh, such that H was principally dominant in the dry season and LE was strongly dominant in the wet season. The Bowen ratio was high for much of the dry season (1.5-2.4), but relatively low (<0.7) in the wet season. Net radiation strongly influenced H and LE fluxes across nearly all seasons and years ( Radj2=0.48-0.79). However, the 2009 dry season LE data were not consistent with this relationship ( Radj2=0.08) because of low seasonal variation in LE following a prolonged end to the previous wet season. In addition to net radiation, H and LE fluxes were significantly related to soil volumetric water content (VWC), water depth, air temperature, and occasionally vapor pressure deficit. Given that VWC and water depth were determined in part by water management decisions, it is clear that human actions have the ability to influence the mode of energy dissipation from this ecosystem. Impending modifications to water management under the Comprehensive Everglades Restoration Plan may shift the dominant turbulent flux from this ecosystem further toward LE, and this change will likely affect local hydrology and climate.

    The accurate partitioning of available energy into sensible and latent heat flux is crucial to the understanding of surface atmosphere interactions. This issue is more complicated in arid and semi arid regions where the relative contribution to surface fluxes from the soil and vegetation may vary significantly throughout the day and throughout the season. A three component model to estimate sensible heat flux over heterogeneous surfaces is presented. The surface was represented with two adjacent compartments. The first compartment is made up of two components, shrubs and shaded soil, the second of open 'illuminated' soil. Data collected at two different sites in Nevada (U.S.) during the Summers of 1991 and 1992 were used to evaluate model performance. The results show that the present model is sufficiently general to yield satisfactory results for both sites.

    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.

    Sound application of clinical reasoning (CR) by the physical therapist is critical to achieving optimal patient outcomes. As such, it is important for institutions granting certification in orthopaedic manual physical therapy (OMPT) to ensure that the assessment of CR is sufficiently robust. At present, the dearth of validated instruments to assess CR in OMPT presents a serious challenge to certifying institutions. Moreover, the lack of documentation of the development process for instruments that measure CR pose additional challenges. The purpose of this study is to evaluate the sensibility of a newly developed instrument for assessing written responses to a test of CR in OMPT; a 'pilot' phase that examines instrument feasibility and acceptability. Using a sequential mixed-methods approach, Canadian OMPT examiners were recruited to first review and use the instrument. Participants completed a sensibility questionnaire followed by semi-structured interviews, the latter of which were used to elaborate on questionnaire responses regarding feasibility and acceptability. Eleven examiners completed the questionnaire and interviews. Questionnaire results met previously established sensibility criteria, while interview data revealed participants' (dis)comfort with exerting their own judgment and with the rating scale. Quantitative and qualitative data provided valuable insight regarding content validity and issues related to efficiency in assessing CR competence; all of which will ultimately inform further psychometric testing. While results suggest that the new instrument for assessing clinical reasoning in the Canadian certification context is sensible, future research should explore how rater judgment can be utilized effectively and the mental workload associated with appraising clinical reasoning.

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

  9. The farming system sensibility of the Normandy in connection with the Climatic Change (2000-2100)

    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 to design a map of the available water content of soils for the 1:25,000 scale. Thereafter, the modelling and the mapping of the local evapotranspiration conditions as well as the departmental mapping of rainfalls have permitted to elaborate a calculation algorithm of hydrological balance with fine spatial resolution. The estimate and the cartographic representation of the soil dryness (hydrous deficit) for the current period and 2100 according to the scenario A1B have been obtained then by requests of the pedo-climatic database. For the current period, as far as Calvados is concerned, the results show that, the dryness of the agricultural soils of low intensity concerns a little more than 1100 km², which means one the third of the agricultural area (3500 km²). The soil dryness of strong intensity appears very circumscribed since it extends only on 182 km² (approximately 5% of agricultural area). For 2100, the results are particularly alarming. They testify to a spectacular increase in the agricultural area touched by soil dryness with a strong intensity. These would represent nearly 2500 km², which represents 70% of the agricultural area. If this kind of scenario was to be confirmed, it is all the agricultural economy of Normandy which would be deeply affected.

    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. PMID:15826308

    The Tibetan Plateau (TP) has become a focus of strong scientific interest due to its role in the global water cycle and its reaction to climate change. Regional flux estimates of sensible and latent heat are important variables for linking the energy and hydrological cycles at the TP's surface. Within this framework, a 3-year dataset (2008-2010) of eddy covariance measured turbulent fluxes was compiled from four stations on the TP into a standardised workflow: corrections and quality tests were applied using an internationally comparable software package. Second, the energy balance closure ( C EB) was determined and two different closure corrections applied. The four stations (Qomolangma, Linzhi, NamCo and Nagqu) represent different locations and typical land surface types on the TP (high altitude alpine steppe with sparse vegetation, a densely vegetated alpine meadow, and bare soil/gravel, respectively). We show that the C EB differs between each surface and undergoes seasonal changes. Typical differences in the turbulent energy fluxes occur between the stations at Qomolangma, Linzhi and NamCo, while Nagqu is quite similar to NamCo. Specific investigation of the pre-monsoon, the Tibetan Plateau summer monsoon, post-monsoon and winter periods within the annual cycle reinforces these findings. The energy flux of the four sites is clearly influenced by the Tibetan Plateau monsoon. In the pre-monsoon period, sensible heat flux is the major energy source delivering heat to the atmosphere, whereas latent heat flux is greater than sensible heat flux during the monsoon season. Other factors affecting surface energy flux are topography and location. Land cover type also affects surface energy flux. The energy balance residuum indicates a typically observed overall non-closure in winter, while closure (or `turbulent over-closure') is achieved during the Tibetan Plateau summer monsoon at the Nagqu site. The latter seems to depend on ground heat flux, which is higher in the wet season, related not only to a larger radiation input but also to a thermal decoupling of dry soils. Heterogeneous landscape modelling using a MODIS product is introduced to explain energy non-closure.

    In June 1991, a field study of surface fluxes of latent and sensible heat over heterogeneous surfaces was carried out near Boardman, Oregon (Doran et al., 1992). The object of the study was to develop improved methods of extrapolating from local measurements of fluxes to area-averaged values suitable for use in general circulation models (GCMs) applied to climate studies. A grid element in a GCM is likely to encompass regions whose fluxes vary significantly from one surface type to another. The problem of integrating these fluxes into a single, representative value for the whole element is not simple, and describing such a flux in terms of flux-gradient relationships, as is often done, presents additional difficulties.

    A simple eddy correlation system is presented that allows on-line calculation of latent and sensible heat fluxes. The system is composed of a three dimensional propeller anemometer, a thermocouple and a capacitance relative humidity sensor. Results from two contrasting sites demonstrate the capability of the system to measure turbulent fluxes under varying conditions. A dry mixed (dominantly coniferous) forest in hilly terrain in Austria is compared to a well irrigated, heavily transpiring, deciduous pecan orchard in the Southwest of the US. The US site shows insufficient closure of the energy balance that is attributed to non-turbulent fluxes under advective conditions in a stable boundary layer (Blanford et al., 1991) while the Austrian site exhibits almost perfect closure with the use of the very same instruments when the boundary layer is convective and advection is negligible.

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

    2000-01-01

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

  15. Estimating sensible heat exchange between screen-covered canopies and the atmosphere using the surface renewal technique

    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 ?m) exposed T-type thermocouples were placed at several heights. Thermocouple output was continuously recorded at 10 Hz and data analysis was performed at 10, 5, 2 and 1 Hz to examine the validity of low frequency data acquisition. Results for daytime hours revealed temperature ramp amplitudes of up to 2ºC, with ramp periods spanning from several to tens of seconds. Best linear regressions between EC and SR sensible heat fluxes during validation were obtained for the thermocouples located above the screen, 0.1 m above the shading screen and 0.45 m above the insect-proof screen. The coefficients of determination were generally higher for the shading than the insect-proof screenhouses. This was due to the effect of the insect-proof screen which induces a higher resistance to airflow than the more porous shading screen that covers the banana plantation. At both campaigns, results were better for unstable than for stable boundary layers. At unstable conditions and above the canopy, low frequency data analysis produced reasonable results, such that 2 Hz analysis performed as good as 10 Hz. Parameters like turbulence intensity, two-point correlation and quadrant analysis illustrate the effect of the two different screenhouses on turbulence characteristics of the flow.

    Radiometric surface temperature images from aircraft observations over the Walnut Gulch Experimental Watershed, a semiarid rangeland watershed, were used with ground-based meteorological data at a reference site for extrapolating estimates of surface sensible heat flux across the basin. Two approaches were used. One method assumed that the resistance to heat transport and other meteorological data at a reference site were constant over the watershed. This resulted in a simple scheme (constant resistance approach) for computing spatially distributed sensible heat flux since the variation in sensible heat flux was directly proportional to surface temperature differences from the reference site. The second approach (the variable resistance approach) used spatially distributed estimates of the surface roughness for momentum and heat, as well as air temperature and wind speed. The sensible heat flux values derived by both techniques were compared to measurements made at several other locations in the watershed for three different days. The environmental conditions for these days ranged from uniformly dry surface soil moisture to variably wet conditions caused by several high intensity and spatially variable rainfall events. Comparisons between these two schemes with observations indicated that the more detailed method of accounting for changes in surface roughness over the basin gave significantly better agreement than the simpler scheme. The average percentage of difference with measured values was 30% for the constant resistance approach compared to approximately 20% for the variable resistance method.

    Due to the wide and deep application of Large Aperture Scintillometer (LAS), the scintillation method exhibits as a robust technique in measuring area-averaged sensible heat fluxes. As the path length of LAS is comparable to the pixel size of satellite images and grid scale of hydrological models, the measurements are helpful for validation. Meanwhile LAS has the potential to explore the scale effect, especially to bridge the gap from local to regional flux measurement. In our analysis, the ground measurements including LAS, Eddy Covariance (EC) system and Automatic Weather System(AWS), as well as TM/MODIS satellite in Miyun, Guantao and Daxing sites over Hai River Basin from 2008-2009 were selected, which can represent three different heterogeneous surfaces in Hai River Basin. After data processing and quality control, continuous sensible heat flux (Hlas) data on Kilometers Scale were obtained over various surfaces. Based on the footprint model of LAS, the distribution of source area for LAS measurements had been analyzed over Miyun, Guantao and Daxing sites in January, April, July and October, 2008. And then the daily variation of Hlas in January, April, July and October in 2008 over the three sites have been analyzed; the value and tendency of variation in these months are different among these sites, which are in accordance with the local crop phenophases. From the comparison of daily mean net radiation (Rn) and Hlas from 2008-2009 over the three sites, it can be seen the seasonal variation of Hlas are consistent in these two years, however, Miyun site shows a single peak while Guantao and Daxing sites show double-peak variation of Hlas, which mainly due to the different crop phenophases and irrigation conditions. At last, the difference between Hlas and Hec in Miyun and Guantao sites had been discussed separately. In accordance with the underlying surfaces, the reasons for the difference between Hlas and Hec can be attributed to the energy balance ratio of EC, the heterogeneity of the underlying surfaces as well as the relative weights of the overlap area between EC and LAS measurements. While in Guantao site, apart from the above reasons mentioned in Miyun site, the atmospheric instability may be one of the main reasons that contribute to the difference between Hlas and Hec.

    Bat wings are important for thermoregulation, but their role in heat balance during flight is largely unknown. More than 80% of the energy consumed during flight generates heat as a by-product, and thus it is expected that bat wings should dissipate large amounts of heat to prevent hyperthermia. We measured rectal (T(r)) and surface (T(s)) temperatures of Brazilian free-tailed bats (Tadarida brasiliensis) as they emerged from and returned to their daytime roosts and calculated sensible heat transfer for different body regions (head, body, wings, and tail membrane). Bats' T(r) decreased from 36.8°C during emergence flights to 34.4°C during returns, and T(s) scaled positively with ambient temperature (T(a)). Total radiative heat loss from bats was significantly greater for a radiative sink to the night sky than for a sink with temperature equal to T(a). We found that free-ranging Brazilian free-tailed bats, on average, do not dissipate heat from their wings by convection but instead dissipate radiative heat (L) to the cloudless night sky during flight ([Formula: see text] W). However, within the range of T(a) measured in this study, T. brasiliensis experienced net heat loss between evening emergence and return flights. Regional hypothermia reduces heat loss from wings that are exposed to potentially high convective fluxes. Additional research is needed to establish the role of wings in evaporative cooling during flight in bats. PMID:21034204

    Sensible heat fluxes () are determined using scintillometry and eddy covariance over a suburban area. Two large-aperture scintillometers provide spatially integrated fluxes across path lengths of 2.8 and 5.5 km over Swindon, UK. The shorter scintillometer path spans newly built residential areas and has an approximate source area of 2-4 , whilst the long path extends from the rural outskirts to the town centre and has a source area of around 5-10 . These large-scale heat fluxes are compared with local-scale eddy-covariance measurements. Clear seasonal trends are revealed by the long duration of this dataset and variability in monthly is related to the meteorological conditions. At shorter time scales the response of to solar radiation often gives rise to close agreement between the measurements, but during times of rapidly changing cloud cover spatial differences in the net radiation () coincide with greater differences between heat fluxes. For clear days lags , thus the ratio of to increases throughout the day. In summer the observed energy partitioning is related to the vegetation fraction through use of a footprint model. The results demonstrate the value of scintillometry for integrating surface heterogeneity and offer improved understanding of the influence of anthropogenic materials on surface-atmosphere interactions.

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

    Carbon dioxide, latent and sensible energy fluxes were measured by means of the eddy covariance method above a mountain meadow situated on a steep slope in the Stubai Valley/Austria, based on the hypothesis that, due to the low canopy height, measurements can be made in the shallow equilibrium layer where the wind field exhibits characteristics akin to level terrain. In order to test the validity of this hypothesis and to identify effects of complex terrain in the turbulence measurements, data were subjected to a rigorous testing procedure using a series of quality control measures established for surface layer flows. The resulting high-quality data set comprised 36 % of the original observations, the substantial reduction being mainly due to a change in surface roughness and associated fetch limitations in the wind sector dominating during nighttime and transition periods. The validity of the high-quality data set was further assessed by two independent tests: i) a comparison with the net ecosystem carbon dioxide exchange measured by means of ecosystem chambers and ii) the ability of the eddy covariance measurements to close the energy balance. The net ecosystem CO2 exchange measured by the eddy covariance method agreed reasonably with ecosystem chamber measurements. The assessment of the energy balance closure showed that there was no significant difference in the correspondence between the meadow on the slope and another one situated on flat ground at the bottom of the Stubai Valley, available energy being underestimated by 28 and 29 %, respectively. We thus conclude that, appropriate quality control provided, the eddy covariance measurements made above a mountain meadow on a steep slope are of similar quality as compared to flat terrain.

  7. Combining the bulk transfer formulation and surface renewal analysis for estimating the sensible heat flux without involving the parameter kB-1

    NASA Astrophysics Data System (ADS)

    2014-10-01

    The single-source bulk transfer formulation (based on the Monin-Obukhov Similarity Theory, MOST) has been used to estimate the sensible heat flux, H, in the framework of remote sensing over homogeneous surfaces (HMOST). The latter involves the canopy parameter, kB-1, which is difficult to parameterize. Over short and dense grass at a site influenced by regional advection of sensible heat flux, HMOST with kB-1 = 2 (i.e., the value recommended) correlated strongly with the H measured using the Eddy Covariance, EC, method, HEC. However, it overestimated HEC by 50% under stable conditions for samples showing a local air temperature gradient larger than the measurement error, 0.4 km-1. Combining MOST and Surface Renewal analysis, three methods of estimating H that avoid kB-1 dependency have been derived. These new expressions explain the variability of H versus u*>(Tc-T>(z>)>), where u* is the friction velocity, Tc is the radiometric surface temperature, and T>(z>) is the air temperature at height, z. At two measurement heights, the three methods performed excellently. One of the methods developed required the same readily/commonly available inputs as HMOST due to the fact that the ratio between >(Tc-T>(z>)>) and the ramp amplitude was found fairly constant under stable and unstable cases. Over homogeneous canopies, at a site influenced by regional advection of sensible heat flux, the methods proposed are an alternative to the traditional bulk transfer method because they are reliable, exempt of calibration against the EC method, and are comparable or identical in cost of application. It is suggested that the methodology may be useful over bare soil and sparse vegetation.

    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. PMID:20578433

    To understand the carbon and energy exchange between the lake surface and the atmosphere, direct measurements of latent, sensible heat, and CO2 fluxes were taken using the eddy covariance (EC) technique in Western Lake Erie during October 2011 to September 2013. We found that the latent heat flux (LE) had a marked one-peak seasonal change in both years that differed from the diurnal course and lacked a sinusoidal dynamic common in terrestrial ecosystems. Daily mean LE was 4.8 ± 0.1 and 4.3 ± 0.2 MJ m-2 d-1 in Year 1 and Year 2, respectively. The sensible heat flux (H) remained much lower than the LE, with a daily mean of 0.9 ± 0.1 and 1.1 ± 0.1 MJ m-2 d-1 in Year 1 and Year 2, respectively. As a result, the Bowen ratio was <1 during most of the 2 year period, with the lowest summer value at 0.14. The vapor pressure deficit explained 35% of the variation in half hourly LE, while the temperature difference between the water surface and air explained 65% of the variation in half hourly H. Western Lake Erie acted as a small carbon sink holding -19.0 ± 5.4 and -40.2 ± 13.3 g C m-2 in the first and second summers (May-September) but as an annual source of 77.7 ± 18.6 and 49.5 ± 17.9 g C m-2 yr-1 in Year 1 and Year 2, respectively. The CO2 flux (FCO2) rate varied from -0.45 g C m-2 d-1 to 0.98 g C m-2 d-1. Similar to LE, FCO2 had noticeable diurnal changes during the months that had high chlorophyll a months but not during other months. A significantly negative correlation (P < 0.05) was found between FCO2 and chlorophyll a on monthly fluxes. Three gap-filling methods, including marginal distribution sampling, mean diurnal variation, and monthly mean, were quantitatively assessed, yielding an uncertainty of 4%, 6%, and 10% in LE, H, and FCO2, respectively.

  10. The Time-lagged Impacts of Spring Sensible Heat over the Tibetan Plateau on the Summer Rainfall Anomaly in East China: Cases Study by Using WRF Model

    2014-12-01

    This study explores the time-lagged impacts of the spring sensible heat (SH) source over the Tibetan Plateau (TP) on summer rainfall anomaly in east China by using the WRF model. Numerical experiments for the 2003 case indicates that spring SH anomaly over the TP can maintains its impact until summer and leads to the overall strong atmospheric heat source, which is characterized by the enhanced both SH over the western TP and condensation latent heat to the east. The wave activity diagnosis revealed that the enhanced TP heating forces a Rossby wave train to the downstream regions. The cyclonic response to the northeast TP brings about the low level northerly anomaly over the northern China, while the anticyclonic response over the western Pacific enhances the subtropical high and the low level southerly in its western flank. As a result, cold and dry airflows from mid-high latitudes and warm and wet airflows from tropical oceans converge around the Huaihe River basin. In addition, warm advection originated from the TP induces vigorous ascending motion over the convergence belt. With such a favourable circulation condition, the eastward propagating vortexes initiated over the TP intensify the torrential rainfall processes over the Huaihe River basin. Another case study of 2001 with weak spring SH over the TP and the overall southward retreat of summer rainfall belt in east China further demonstrates the role of spring SH over the TP in regulating the interannual variability of EASM in terms of wave activity and synoptic disturbance.

  14. Modelling of evaporation in a sparse millet crop using a two-source model including sensible heat advection within the canopy

    Lund, M. R.; Soegaard, H.

    2003-09-01

    During two successive growing seasons meteorological measurements were made in a pearl millet field in the Sahel to investigate the evaporation process in relation to crop growth. The evaporation was measured by eddy correlation and simulated using the Shuttleworth Wallace (SW) model [Q. J. R. Meteorol. Soc. 111 (1985) 839-855]. To take sun height and multi-layer scattering into account a radiation balance model was formulated. The model indicates that partitioning of the net radiation between the vegetation and the soil may be estimated ( r2=0.94) from the fraction of diffuse radiation, the leaf area index and an attenuation coefficient, but that the attenuation coefficient may not be similar in different locations. To solve the SW-model with respect to the soil resistance an iterative solution was employed with the total evaporation estimated from the Bowen-ratio calculated from eddy correlation measurements. The procedure made it possible to derive stable estimates of soil resistance at soil evaporation rates down to 25 W m -2. The soil resistance was found to be in accordance with evaporation through a dry surface layer. The SW-model indicates, that advection of sensible heat from the dry soil to the plants, increases transpiration considerably. This will cause management techniques, such as mulching and dry farming, aimed at reducing soil evaporation to be less effective than might be anticipated. The effects of raising the leaf area index to improve the microclimate is discussed in relation to management of the available water and crop security.

    2014-09-16

    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 amore »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 typically reported in the literature, our estimates for the above-canopy Stanton number were much larger, which likely leads to underestimated modeled sensible heat fluxes above dark warm closed canopies.« less

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

As nurses, we have the privilege of hearing the particular, gaining understanding, and creating a powerful encounter that has healing and health benefits. This is a call for nurses to more intentionally invite and listen to the stories of persons living with illness. The mnemonic STORIED is offered to help nurses weave together essential elements of a narrative practice approach: Subjective, Tell/Listen, Openness, Reflection, Invite/Intention, Engage, and Document. Nurses are the voice of the vulnerable, and to learn to listen to our patients' stories such that what is gleaned contributes to their healing is nothing less than a call to excellent care of the unique person before us.

    We think that psychological interaction is necessary for smooth communication between robots and people. One way to psychologically interact with others is through facial expressions. Facial expressions are very important for communication because they show true emotions and feelings. The ``Ifbot'' robot communicates with people by considering its own ``emotions''. Ifbot has many facial expressions to communicate enjoyment. We developed a method for generating facial expressions based on human subjective judgements mapping Ifbot's facial expressions to its emotions. We first created Ifbot's emotional space to map its facial expressions. We applied a five-layer auto-associative neural network to the space. We then subjectively evaluated the emotional space and created emotional regions based on the results. We generated emotive facial expressions using the emotional regions.

    Over the past three years, the Los Angeles Department of Water and Power (LADWP) has developed an open, proactive approach to address the electromagnetic fields (EMF) issue. Many things gave impetus to this approach: the public's increasing concern about possible health effects associated with EMF; litigation and other difficulties utilities experience when attempting to construct electric facilities; and media coverage fueling public concern about the issue. For LADWP, management of this issue involves a communications and a policy development effort, both of them significant. As an integral part of managing this issue, LADWP has taken steps to reduce fields associated with new projects on a case-by-case basis where economically justified, and supported EMF research, including support for a national EMF research program. Also, LADWP continues its full support for and participation in the Electric Power Research Institute's (EPRI) EMF research program. In the discussion here, references to EPRI reports, bulletins, and technical papers have intentionally been excluded, since their inclusion would overwhelm the footnotes to this paper. Finally, LADWP has purposefully sought additional guidance from other individuals and public policy agencies, many of whose works are cited here.

    2011-02-01

    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.

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

    PubMed

    Mupparapu, Muralidhar

    2008-03-01

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

    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.

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

    NASA Astrophysics Data System (ADS)

    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.

    In recent years, the problem of characterizing turbulent fluxes of heat, momentum, and moisture over inhomogeneous surfaces has received increasing attention. This issue is relevant to the performance of general circulation models (GCMs), in which a single grid element can encompass a variety of surface and topographical features. Although considerable progress has been made in describing the energy balance at a surface partially covered by vegetation, less is known about how to treat adjacent regions of sharply contrasting surface characteristics. One difficulty is the scarcity of suitable data sets with which to study the problem, particularly on scales of tens to hundreds of kilometers.

  6. An experimental and numerical study of boundary layer structure over areas of inhomogeneous sensible heat fluxes

    1994-03-01

    In June of 1992 a boundary-layer experiment was carried out near Boardman, Oregon. The campaigns were part of a program of studies under the auspices of the US Department of Energy`s Atmospheric Radiation Measurement (ARM) program, whose goal is to improve the treatment of radiative transfer, particularly as affected by clouds, in general circulation models (GCMs) used for climate studies. One aspect of this program is concerned with the determination of appropriate lower boundary conditions for such models and the representation of subgrid-scale variability in regions where the surface conditions are not uniform. To study this problem, boundary-layer and surface properties were measured over a region of two sharply contrasting land types: a large, dry, sagebrush steppe area and irrigated farmland that formed the east, northeast, and western borders of the steppe. A combination of surface flux instrumentation, airsondes, sodars, and near-surface wind and temperature sensors was used. Measurements were carried out over the eastern portion of this region, which featured a well-defined boundary between the dry and irrigated areas. In this paper, the authors present some results from those observations and from a set of numerical simulations that address the effects of inhomogeneous surface fluxes on boundary-layer structure.

    We show that the stability constant of the Lennard-Jones potential in , , is smaller than 14.316. This is remarkably smaller than the best previously known bound. Our method is very elementary, and probably applicable to other similar potentials such as the Morse potentials. We also improve slightly, in the Lennard-Jones case, the lower bound for the minimum interparticle distance of an optimal n-particle configuration to 0.684.

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

    Project STORY is a 3-arm, randomized, planning and feasibility study assessing the effectiveness of two behavioral weight management interventions in an important and at-risk population, overweight children and their parents in medically underserved rural counties. Participants will include 90 parent-child dyads from rural counties in north central Florida. Families will be randomized to one of three conditions: (a) a Family-Based Behavioral Group Intervention, (b) a Parent-Only Behavioral Group Intervention, and (c) a waitlist control condition. Child and parent participants will be assessed at baseline (month 0), post-treatment (month 4) and follow-up (month 10). Assessment and intervention sessions will be held at Cooperative Extension offices within each local participating county. The primary outcome measure is change in child body mass index (BMI) z-score. Additional key outcome measures include child dietary intake, physical activity, self-esteem, body image, and parent BMI. The goals of the study are to (a) assess the feasibility of recruitment in rural settings, (b) develop and evaluate training protocol for group leaders, (c) determine strategies to increase adherence to monitoring and goal setting protocol, (d) evaluate strategies for participant retention, (e) assess the relative cost-effectiveness of the interventions, (f) assess the acceptability of the intervention to families and Cooperative Extension administrators and personnel, and (g) if successful, estimate the sample size needed for a full scale trial. This research has potential implications for medically underserved rural communities with limited resources and preventive health care services. If successful, a Parent-Only intervention program may provide a cost-effective and practical intervention for families in underserved rural communities. PMID:17588503

    2008-10-01

    The difference which one remarks in the man and the woman, comes not only from education, but also from their nature. The fibers of the woman are ordinarily more slender, which makes the senses more fine, and the interior sentiment more delicate. This natural disposition makes them prefer perceptible objects to metaphysical realities, amiable qualities to essential qualities, the brilliant to the solid, luxury and ostentation to cleanliness and commodity. It's also what makes them sensitive to piety, inconstant and light, and often capricious. The trace which objects leave there not being profound enough, it is easily effaced by a new impression: in such a way that in their minds the present object often sweeps away that which is absent.

    Application of high pressure can be used for gentle pasteurizing of food, minimizing undesirable alterations such as vitamin losses and changes in taste and color. In addition, pressure has become a useful tool for investigating structural changes in proteins. Treatments of proteins with high pressure can reveal conformations that are not obtainable by other physical variables like temperature, since pressure favors structural transitions accompanied with smaller volumes. Here, we discuss both the potential use of high pressure to inactivate infectious TSE material and the application of this thermodynamic parameter for the investigation of prion folding. This review summarizes our findings on the effects of pressure on the structure of native infectious scrapie prions in hamster brain homogenates and on the structure of infectious prion rods isolated from diseased hamsters brains. Native prions were found to be pressure sensitive, whereas isolated prions revealed an extreme pressure-resistant structure. The discussion will be focused on the different pressure behavior of these prion isoforms, which points out differences in the protein structure that have not been taken into consideration before.

    2012-03-01

    How to redesign the incentives structure in the United States to reward effective coordinated care rather than production volume is a staggering public health policy challenge. In the mind of the public, there is a fine distinction between health care rationing and rational health care. Specialists have a vital but underappreciated role in reining in health care costs, but specific incentives to elicit behavior change with positive social outcomes remain ambiguous. It is imperative, therefore, that redesigning the incentives structure is thoughtfully considered, modeled, and tested prior to implementation, lest an inferior-quality model is inadvertently adopted and costs are only marginally contained. Quality metrics need to be universal and reflect real patient outcomes instead of the degree of investment by the institution in the reporting tools. Still, specialists should take immediate action to implement safe and efficient procedures and to assess their long-term impact on patients' quality of life. Scientific evaluations should guide both the assessment of the appropriateness and the safe delivery of care. Investment in high-quality data architecture and the science of health delivery implementation is an imperative if health care reform is to achieve its goals. Coordination and collaboration between specialists and primary care physicians is essential to this enterprise. Specialists can champion these efforts as they pertain to their areas of expertise by considering their care episodes in the context of the patient as a whole, working closely with generalists, and returning to the mindset of the specialist as a family doctor.

    Summary 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. PMID:26199853

    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.

    2015-01-01

    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.

    NASA Astrophysics Data System (ADS)

    Kärner, Olavi; Post, Piia

    2015-08-01

    The customary representation of climate using sample moments is generally biased due to the noticeably nonstationary behaviour of many climate series. In this study, we introduce a moment-free climate representation based on a statistical model fitted to a long-term daily air temperature anomaly series. This model allows us to separate the climate and weather scale variability in the series. As a result, the climate scale can be characterized using the mean annual cycle of series and local air temperature tolerance, where the latter is computed using the fitted model. The representation of weather scale variability is specified using the frequency and the range of outliers based on the tolerance. The scheme is illustrated using five long-term air temperature records observed by different European meteorological stations.

    An experiment was conducted to investigate the extent of caloric compensation to differential preloading among normally restrained and unrestrained female subjects. Subjects' eating was either explicitly observed or unobserved by the experimenter. Unrestrained eaters compensated appropriately for the preload, whether or not they were observed. Restrained eaters failed to compensate when unobserved , but compensated strongly when observed. A subsequent unobserved eating task revealed that restrained eaters failed to compensate for prior consumption when the observer was withdrawn. Implications for research and therapy are discussed.

    Will there be a next nuclear era and, if so, what conditions will have to be met to encourage utilities to place new nuclear orders. Whereas utilities were once isolated businesses, they now find themselves in a socio/political/economic squeeze between changing national energy policies, continually evolving public opinion, and cyclic economic conditions. As a result, the technical design requirements for an electrical generating system qualified to meet these changing demands continue to evolve. The purposes of the present paper are to explore these changing pressure points and to assess whether the Liquid Metal Cooled Reactor concept has sufficient versatility to allow this type of reactor to be effectively included in utility planning. 3 refs., 5 figs., 2 tabs.

  10. Canine Sense and Sensibility: Tipping Points and Response Latency Variability as an Optimism Index in a Canine Judgement Bias Assessment

    PubMed Central

    Starling, Melissa J.; Branson, Nicholas; Cody, Denis; Starling, Timothy R.; McGreevy, Paul D.

    2014-01-01

    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.

  11. Membrane Dehumidifier: High-Efficiency, On-Line Membrane Air Dehumidifier Enabling Sensible Cooling for Warm and Humid Climates

    SciTech Connect

    2010-09-01

    BEETIT Project: ADMA Products is developing a foil-like membrane for air conditioners that efficiently removes moisture from humid air. ADMA Products’s metal foil-like membrane consists of a paper thin, porous metal sheet coated with a layer of water-loving molecules. This new membrane allows water vapor to permeate across the membrane at high fluxes and at the same time, blocks air penetration efficiently resulting in high selectivity. The high selectivity of the membrane translates to less energy use, while the high permeation fluxes result in a more compact device. The new materials and the flat foil-like nature of the membrane facilitate the mass production of a low-coast compact dehumidification device

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

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

    PubMed

    Starling, Melissa J; Branson, Nicholas; Cody, Denis; Starling, Timothy R; McGreevy, Paul D

    2014-01-01

    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. PMID:25229458

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

    NASA Astrophysics Data System (ADS)

    Reckien, D.

    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.

  2. Making Carbon Emissions Remotely Sensible: Flux Observations of Carbon from an Airborne Laboratory (FOCAL), its Near-Surface Survey of Carbon Gases and Isotopologues on Alaska's North Slope

    Detailed process-oriented study of the mechanisms of conversion in the Arctic of fossil carbon to atmospheric gas is progressing, but necessarily limited to a few point locations and requiring detailed subsurface measurements inaccessible to remote sensing. Airborne measurements of concentration, transport and flux of these carbon gases at sufficiently low altitude to reflect surface variations can tie such local measurements to remotely observable features of the landscape. Carbon dioxide and water vapor have been observable for over 20 years from low-altitude small aircraft in the Arctic and elsewhere. Methane has been more difficult, requiring large powerful aircraft or limited flask samples. Recent developments in spectroscopy, however, have reduced the power and weight required to measure methane at rates suitable for eddy-covariance flux estimates. The Flux Observations of Carbon from an Airborne Laboratory (FOCAL) takes advantage of Integrated Cavity-Output Spectroscopy (ICOS) to measure CH4, CO2, and water vapor in a new airborne system. The system, moreover, measures these gases' stable isotopologues every two seconds or faster helping to separate thermogenic from biogenic emissions. Paired with the Best Airborne Turbulence (BAT) probe developed for small aircraft by NOAA's Air Resources Laboratory and a light twin-engine aircraft adapted by Aurora Flight Sciences Inc., the FOCAL measures at 6 m spacing, covering 100 km in less than 30 minutes. It flies between 10 m and 50 m above ground interspersed with profiles to the top of the boundary layer and beyond. This presentation gives an overview of the magnitude and variation in fluxes and concentrations of CH4, CO2, and H2O with space, time, and time of day in a spatially extensive survey, more than 7500 km total in 15 flights over roughly a 100 km square during the month of August 2013. An extensive data set such as this at low altitude with high-rate sampling addresses features that repeat on 1 km scale or smaller such as thermokarst lakes as well as landscape changes on the 100 km scale.

    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.

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

    Lefrère, Jean-Jacques; Hewitt, Patricia

    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.

    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.

    Dans cette etude, nous souhaitions principalement greffer des groupements phosphates directement sur la cellulose comme materiau modele, et par la suite transposer les conditions optimales du design concu pour la cellulose, determine par modelisation a l'aide de l'outil JMP, sur la pate kraft. Ensuite, evaluer les proprietes physico-chimiques, optiques, d'hydrophilie, thermiques et d'inflammabilite des materiaux fabriques (feuilles ou pastilles fabriquees) a partir des fibres phosphorylees. Pour ce faire, nous avons pretraite la cellulose et la pate kraft dans une solution aqueuse de 10 a 15 % de LiCl a 70°C pendant 7 heures. Par la suite, nous avons procede a la reaction de phosphorylation in situ avec l'acide phosphorique et l'uree, dans des conditions de temperatures et de reactifs decrites par un design experimental, pendant 3 heures. La reaction de phosphorylation s'est realisee avec succes pour l'ensemble des resultats sur la cellulose, avec des taux de greffage variables selon les conditions operatoires. Les degres de substitutions (DSP), determines par ICP-OES, et les degres de polymerisation (DP), determines par viscosimetrie, etaient aussi variables, selon les conditions. L'etude des parametres experimentaux a permis de determiner les conditions optimales transposables sur la pate kraft (DSP = 1,47 et DP = 142,42 pour la cellulose, qui represente un taux de coupure de 38% de la fibre) et les facteurs critiques de la reaction. Les resultats de la reaction sur la fibre ont permis, non seulement de constater que les conditions utilisees pour la cellulose n'etaient directement transposables a la fibre, mais permettaient quand d'obtenir un DSP interessant ? a 1 avec un taux de coupure de 50 a 60 %. La structure du produit principal de la reaction (le sel de calcium du pyrophosphate d'ester de cellulose ou de pate kraft) a ete determinee par les analyses FTIR, XPS, RMN-13C et RMN-31P. L'etude de l'effet de la reaction de phosphorylation sur les proprietes physico-chimiques et optiques (blancheur/opacite, rupture, cohesion interne etc.) des feuilles fabriquees a permis de demontrer une diminution generale des proprietes de ces dernieres. De meme, une resistance a la flamme du papier phosphoryle a ete observee dans la phase de decroissance de la combustion, lors des tests de flamme et des analyses par TGA. De plus, l'analyse de l'angle de contact a demontre que le greffage des groupements phosphates augmentait l'hydrophilie de la fibre et son absorption d'eau.

    A method of breast reconstruction is based on the Deep Inferior Epigastric Perforator (DIEP) technique. Skin and fat are transplanted from the abdomen to the chest; blood vessels are reconnected through microsurgery. Nerves are, however, left unconnected. This study aims to evaluate the blood flow and reinnervation of blood vessels and skin in breasts reconstructed by DIEP flaps without neural repair. In all, DIEP flaps of 10 patients were tested at an average of 16.3 months postoperatively. Blood flow was assessed by PeriScan PIM II System, both before and after indirect heating. Tactile perception threshold was assessed by Semmes-Weinstein monofilament and thermal sensibility by SENSELab MSA Thermotest. The patients' contralateral breasts were used as controls. The blood flow of the flaps was statistically significantly lower than in the control breasts, both before and after indirect heating. The change in blood flow after indirect heating did, however, not significantly differ when comparing the breasts. All flaps regained deep pressure sensibility in all four quadrants. Five patients regained even better sensibility in one of their quadrants. Seven patients regained perception of cold stimuli, five perceived warmth. This study has shown that skin blood flow regulation is present in DIEP flaps 1 year after reconstruction. Blood flow dynamics are very similar to those in the normal breast. There is also a recovery of tactile and thermal sensibility, but this study has not shown any clear parallels between recovery blood flow, tactile sensibility and thermal sensibility. PMID:24693867

    2014-01-01

    Schizophrenia patients have been reported to be more impaired in comprehending non-literal than literal language since early studies on proverbs. Preference for literal rather than figurative interpretations continues to be documented. The main aim of this study was to establish whether patients are indeed able to use combinatorial semantic processing to comprehend literal sentences and both combinatorial analysis, and retrieval of pre-stored meanings to comprehend idiomatic sentences. The study employed a sentence continuation task in which subjects were asked to decide whether a target word was a sensible continuation of a previous sentence fragment to investigate idiomatic and literal sentence comprehension in patients with paranoid schizophrenia. Patients and healthy controls were faster in accepting sensible continuations than in rejecting non-sensible ones in both literal and idiomatic sentences. Patients were as accurate as controls in comprehending literal and idiomatic sentences, but they were overall slower than controls in all conditions. Once the contribution of cognitive covariates was partialled out, the response times (RTs) to sensible idiomatic continuations of patients did not significantly differ from those of controls. This suggests that the state of residual schizophrenia did not contribute to slower processing of sensible idioms above and beyond the cognitive deficits that are typically associated with schizophrenia.

    The main goal of this work was to estimate the sensible (H) and latent (LE) heat flux using the eddy covariance method in a Cerrado "Campo Sujo" area, basically with herb-shrub physiognomy, sparse woody vegetation and approximately 2m height. The geographical position of the Cerrado, altitude, latitude, longitude, climate and weather conditions are determined by the dynamics of the atmosphere that affects the whole South America and consequently influence the ecological framework of ecosystems. The results shown by the components considered in the energy balance were more significant during the day, which the atmospheric boundary layer extends from the ground to about 50 or 100 meters height, showing greater instability and turbulence (u* > 0.2 m / s), and this turbulence is what justifies the use of the eddy covariance method to estimate the sensible and latent heat flux. The Cerrado presents seasonal difference between the densities estimates of sensible (H) and latent (LE) heat flux. During the rainy season the sensible heat flux (H) was 25% and the latent heat flux (LE) 54%. During the dry season the sensible heat flux (H) was 42% and the latent heat flux (LE) 30% of the energy budget.

  8. Estimation of Momentum and Heat Fluxes Using Dissipation and Flux-Variance Methods in the Unstable Surface Layer

    NASA Astrophysics Data System (ADS)

    Hsieh, Cheng-I.; Katul, Gabriel G.; Schieldge, John; Sigmon, John; Knoerr, Kenneth R.

    1996-08-01

    Dissipation and flux-variance methods, derived from the turbulent kinetic energy and temperature variance budget equations in conjunction with Monin-Obukov similarity theory, were used to estimate surface fluxes of momentum and sensible heat. To examine the performance of these two methods, direct eddy correlation measurements were carried out above a nonuniform grass-covered forest clearing in Durham, North Carolina. The dissipation method sensible heat flux predictions were in good agreement with eddy correlation measurements. Also, the flux-variance method reproduced the measured sensible heat flux well following an adjustment to the similarity constant. However, the momentum flux (or friction velocity) estimated by the dissipation and flux-variance methods were both inferior to those for sensible heat flux. The data from this experiment indicated that the above two methods are sensitive to the dimensionless wind shear (?m) and temperature standard deviation (??) functions. On the basis of dimensional analysis and the temperature variance budget equation a new dissipation approach for estimating sensible heat flux was derived. The similarity constant for this new approach was shown to be around 1.6 for uniform surfaces and from the data of this experiment.

  9. Influence of Leaf Area Index on the Radiometric Resistance to Heat Transfer

    NASA Astrophysics Data System (ADS)

    Zhao, Lei; Lee, Xuhui; Suyker, Andrew E.; Wen, Xuefa

    2015-09-01

    Sensible heat flux is an important component of the surface energy balance. Land surface models often use the radiative surface temperature instead of the aerodynamic temperature to predict the surface sensible flux, because the former is much easier to observe by remote sensing or to compute from the surface energy balance equation. Here, measurements from 44 FLUXNET sites are used to examine the stability and leaf area index (LAI) dependence of the radiometric resistance, a resistance that should be included in the bulk transfer method if the radiometric temperature is used for the flux calculation. Results show that the radiometric resistance is much higher under stable conditions than under unstable conditions. In unstable conditions, the radiometric resistance is highly sensitive to LAI, decreasing exponentially as LAI increases. Omission of the radiometric resistance from the bulk transfer method causes a large overestimation in the sensible heat flux, especially for low-LAI surfaces and under unstable conditions.

    1993-08-01

    A model is developed to evaluate surface heat flux densities using the radiant surface temperature and red and near-infrared reflectances from the NOAA Advanced Very High Resolution Radiometer sensor. Net radiation is calculated from an empirical formulation and albedo estimated from satellite observations. Infrared surface temperature is corrected to aerodynamic surface temperature in estimating the sensible heat flux and the latent flux is evaluated as the residual of the surface energy balance. When applied to relatively homogeneous agricultural and native vegetation, the model yields realistic estimates of sensible and latent heat flux density in the surface layer for cases where either the sensible or latent flux dominates. 29 refs., 10 figs., 3 tabs.

    The feasibility of using radio frequency receivers to collect data from automated weather stations to model fluxes of latent heat, sensible heat, and radiation using routine weather data collected by automated weather stations was tested and the estimated fluxes were compared with fluxes measured over wheat. The model Cupid was used to model the fluxes. Two or more automated weather stations, interrogated by radio frequency and other means, were utilized to examine some of the climatic variability of the First ISLSCP (International Satellite Land-Surface Climatology Project) Field Experiment (FIFE) site, to measure and model reflected and emitted radiation streams from various locations at the site and to compare modeled latent and sensible heat fluxes with measured values. Some bidirectional reflected and emitted radiation data were collected from 23 locations throughout the FIFE site. Analysis of these data along with analysis of the measured sensible and latent heat fluxes is just beginning.

    Efforts to measure evapotranspiration (ET) remotely are common in agriculture, and the application of such data to irrigation scheduling is readily apparent. Extending this methodology to arid environments is primarily of use as a mechanism for validation of ET algorithms used in large-scale watershed and global climate change modeling efforts. To facilitate testing of the remote sensing method for ET, measurements of sensible and latent heat flux were made at four sites located on the US Department of Energy`s Hanford Site using a combination of lysimeter and Bowen Ratio Energy Balance (BREB) stations. The objective was to calibrate an aerodynamic transport equation that relates sensible heat flux to radiant surface temperature, and to map sensible heat flux using Landsat data.

    2014-02-01

    The anaerobic bacteria resistance to antibiotics is increasing, and even has appeared against the most active of those, like metronidazol and carbapenems. This fact forces to make and periodical sensibility tests -at least in the most aggressive and virulent species, in cases that they are isolated from life locations and in the absence of therapeutic response- to check the local sensibility and to establish suitable empiric therapies, all based on multicentric studies carried out in order to this or well to check the activity of new antibiotics. For the laboratory routine, the easiest sensibility method is the E-test/MIC evaluator. Another alternative is microdilution, that's only normalized for Bacteroides. There are preliminary facts that allow the use of disc diffusion method in some species of Bacteroides and Clostridium. For the temporal and multicentric studies, the procedure is dilution in agar plate, the reference method. PMID:24630580

    1989-01-01

    Surface evaluation of sensible and latent heat flux densities and the components of the radiation balance were desired for various vegetative surfaces during the ASCOT84 experiment to compare with modeled results and to relate these values to drainage winds. Five battery operated data systems equipped with sensors to determine the above values were operated for 105 station days during the ASCOT84 experiment. The Bowen ratio energy balance technique was used to partition the available energy into the sensible and latent heat flux densities. A description of the sensors and battery operated equipment used to collect and process the data is presented. In addition, improvements and modifications made since the 1984 experiment are given. Details of calculations of soil heat flow at the surface and an alternate method to calculate sensible and latent heat flux densities are provided.

    This article reviews some contributions of the Jungian analytic tradition to indigenous ethnopsychiatric thought in Australia. The authors review Jung's writings on Aboriginal culture, then describe some of their own fieldwork findings. Acknowledging that the contemporary post-Jungian tradition is pluralist, they propose a notion of 'Jungian sensibility.' They discuss some of the ways in which the Jungian sensibility might contribute positively to Aboriginal mental health, with especial reference to theories of subjectivity, and note that some Aboriginal people find the Jungian world-view very compatible with the Aboriginal one.

    1984-01-01

    A two year run with the GLAS climate model with prescribed but seasonally varying boundary conditions provided mean monthly fluxes of sensible heat, latent heat, and radiative energy. These fluxes were analyzed to examine the energy exchange processes between the atmosphere and the ice-free ocean. A mean annual plot of monthly zonal fuxes of sensible heat, latent heat, and net radiation was produced. From these, northward transport of heat flux that would follow if the GCM simulated fluxes were consistent with oceanic circulation were produced. These results are compared with observations.

    Air-sea transfers of sensible heat, latent heat, and momentum are computed from twenty-five years of middle-latitude and subtropical ocean weather ship data in the North Atlantic and North Pacific using the bulk aerodynamic method. The results show that monthly-averaged wind speeds, temperatures, and humidities can be used to estimate the monthly-averaged sensible and latent heat fluxes computed from the bulk aerodynamic equations to within a relative error of approximately 10%. The estimate of monthly-averaged wind stress under the assumption of neutral stability are shown to be within approximately 5% of the monthly-averaged non-neutral values.

  18. On the Microphysics Equilibrium of Tropical Convection Derived From Long-Term TRMM Radiance-Based Statistics

    2014-12-01

    Net radiation energy is balanced by vertical transport of latent and sensible heat over the Tropics. This thermal equilibrium is called radiative-convective equilibrium, studied since Manabe and Strickler in 1964. This radiative-convective equilibrium not only creates constant water vapor and temperature structure over tropics, but also creates "microphysics equilibrium" regardless of variability of individual microphysics processes associated with cloud-precipitation dynamics. Here, we summarize 14-year multi-sensor satellite-based statistics to prove microphysics equilibrium over tropics. Statistics are further divided into continental and maritime, and linking to the thermodynamics structure, surface latent/sensible heat flux, and tropospheric aerosol concentrations.

    The midline of the ring finger is classically considered as the neural watershed between the median and ulnar nerve sensory territories on the palmar surfaces of the fingers. Variations of this division exist and may be explained by a communicating branch between the third and fourth common digital nerves. The palmar sensibility patterns of fingers were assessed with Semmes Weinstein filaments after either a complete median or an ulnar nerve transection in 43 patients. Eight out of nine observed sensibility patterns could be explained by known anatomic types and subtypes of the communicating branch. The type of communicating branch, but not its subtype, could be established in the one remaining pattern. PMID:15234498

    ELISA technique in the rabies rapid diagnosis is compared with other methods used in the PASTEUR Institute of MADAGASCAR (immunofluorescence, mouse inoculation, and histopathology). The results of the comparative study of 80 samples of suspect animals show that ELISA sensibility is better than immunofluorescence one. Sensibility, specificity and viability of ELISA are comparable with those of the two confirmation techniques. In MADAGASCAR, ELISA is adapted to testing samples not conserved in good conditions, exposed to heat, after a big travelling time. It is to be hoped that samples are numerous to control rabies: in this condition price of ELISA is not expensive. PMID:2078080

  9. Turbulent heat transfer from a sparsely vegetated surface - Two-component representation

    NASA Technical Reports Server (NTRS)

    Otterman, J.; Novak, M. D.; Starr, D. O'C.

    1993-01-01

    The conventional calculation of heat fluxes from a vegetated surface involving the coefficient of turbulent heat transfer which increases logarithmically with surface roughness, is inappropriate such highly structured surfaces as desert scrub or open forest. An approach is developed here for computing sensible heat flux from sparsely vegetated surfaces, where the absorption of insolation and the transfer of absorbed heat to the atmosphere are calculated separately for the plants and for the soil. This approach is applied to a desert-scrub surface in the northern Sinai, for which the turbulent transfer coefficient of sensible heat flux from the plants is much larger than that from the soil below, as shown by an analysis of plant, soil, and air temperatures. The plant density is expressed as the sum of products (plant-height) x (plant-diameter) of plants per unit horizontal surface area. The solar heat absorbed by the plants is assumed to be transferred immediately to the airflow. The effective turbulent transfer coefficient k(g-eff) for sensible heat from the desert-scrub/soil surface computed under this assumption increases sharply with increasing solar zenith angle, as the plants absorb a greater fraction of the incoming irradiation. The surface absorptivity (the coalbedo) also increases sharply with increasing solar zenith angle, and thus the sensible heat flux from such complex surfaces is a much broader function of time of day than when computed under constant k(g-eff) and constant albedo assumptions.

    NASA Astrophysics Data System (ADS)

    Grunwald, J.; Kalthoff, N.; Corsmeier, U.; Fiedler, F.

    1996-01-01

    In June 1991 the EFEDA-field experiment ( ECHIVAL Field Experiment in a Desertification-Threatened Area) was carried out in the Spanish province Castilla-La Mancha, to improve the understanding of the interactions between the soil, the vegetation and the atmosphere. Here results of energy balance studies at the Barrax site are given, one of the three intensively studied experimental sites within Castilla-La Mancha. This area is characterized by a large fraction of irrigated fields (40%) while the remaining 60% was fallow land at the end of June 1991. The energy balances over these two characteristic land-use classes totally differ. While for the irrigated fields the evapotranspiration is dominant, for the non-irrigated fields the sensible and the soil heat fluxes dominate and the latent heat flux is nearly negligible. In order to achieve areally averaged turbulent fluxes, surface, SODAR and aircraft data have been used. Comparing the surface fluxes from all three facilities, it can be found that: The sensible heat flux estimation from SODAR (?w-method) gives reliable results when a calibration of ?w is done with another independent system (e.g. aircraft). Aircraft measurements in conjunction with energy budget methods yield surface fluxes of sensible heat, which are about 20% lower than the areally averaged values calculated by the surface measurements. The areally averaged latent heat fluxes from aircraft and surface measurements agree better than the sensible heat fluxes.

  2. Estimating ocean-air heat fluxes during cold air outbreaks by satellite

    NASA Technical Reports Server (NTRS)

    Chou, S. H.; Atlas, D.

    1981-01-01

    Nomograms of mean column heating due to surface sensible and latent heat fluxes were developed. Mean sensible heating of the cloud free region is related to the cloud free path (CFP, the distance from the shore to the first cloud formation) and the difference between land air and sea surface temperatures, theta sub 1 and theta sub 0, respectively. Mean latent heating is related to the CFP and the difference between land air and sea surface humidities q sub 1 and q sub 0 respectively. Results are also applicable to any path within the cloud free region. Corresponding heat fluxes may be obtained by multiplying the mean heating by the mean wind speed in the boundary layer. The sensible heating estimated by the present method is found to be in good agreement with that computed from the bulk transfer formula. The sensitivity of the solutions to the variations in the initial coastal soundings and large scale subsidence is also investigated. The results are not sensitive to divergence but are affected by the initial lapse rate of potential temperature; the greater the stability, the smaller the heating, other things being equal. Unless one knows the lapse rate at the shore, this requires another independent measurement. For this purpose the downwind slope of the square of the boundary layer height is used, the mean value of which is also directly proportional to the mean sensible heating. The height of the boundary layer should be measurable by future spaceborn lidar systems.

    NASA Astrophysics Data System (ADS)

    Santanna, F. B.; Arruda, P. H. Z. D.; Pinto-Jr, O. B.

    2014-12-01

    The main goal of this work was to estimate fluxes using the eddy covariance method in a wetland area, basically with herb-shrub physiognomy, sparse woody vegetation and approximately 4m height. The geographical position of the Pantanal, altitude, latitude, longitude, climate and weather conditions are determined by the dynamics of the atmosphere that affects the whole South America and consequently influence the ecological framework of ecosystems. The results shown by the components considered in the energy balance were more significant during the day, which the atmospheric boundary layer extends from the ground to about 50 or 100 meters height, showing greater instability and turbulence (u* > 0.2 m / s), and this turbulence is what justifies the use of the eddy covariance method to estimate the sensible and latent heat flux. The Pantanal presents seasonal difference between the densities estimates of sensible (H) and latent (LE) heat flux. During the rainy season the sensible heat flux (H) was 30% and the latent heat flux (LE) 58%. During the dry season the sensible heat flux (H) was 46% and the latent heat flux (LE) 40% of the energy budget.

    2014-09-01

    Cooling loads must be dramatically reduced when designing net-zero energy buildings or other highly efficient facilities. Advances in this area have focused primarily on reducing a building's sensible cooling loads by improving the envelope, integrating properly sized daylighting systems, adding exterior solar shading devices, and reducing internal heat gains. As sensible loads decrease, however, latent loads remain relatively constant, and thus become a greater fraction of the overall cooling requirement in highly efficient building designs, particularly in humid climates. This shift toward latent cooling is a challenge for heating, ventilation, and air-conditioning (HVAC) systems. Traditional systems typically dehumidify by first overcooling air below the dew-point temperature and then reheating it to an appropriate supply temperature, which requires an excessive amount of energy. Another dehumidification strategy incorporates solid desiccant rotors that remove water from air more efficiently; however, these systems are large and increase fan energy consumption due to the increased airside pressure drop of solid desiccant rotors. A third dehumidification strategy involves high flow liquid desiccant systems. These systems require a high maintenance separator to protect the air distribution system from corrosive desiccant droplet carryover and so are more commonly used in industrial applications and rarely in commercial buildings. Both solid desiccant systems and most high-flow liquid desiccant systems (if not internally cooled) add sensible energy which must later be removed to the air stream during dehumidification, through the release of sensible heat during the sorption process.

  13. On the Interaction between Marine Boundary Layer Cellular Cloudiness and Surface Heat Fluxes

    SciTech Connect

    2014-01-02

    The interaction between marine boundary layer cellular cloudiness and surface uxes of sensible and latent heat is investigated. The investigation focuses on the non-precipitating closed-cell state and the precipitating open-cell state at low geostrophic wind speed. The Advanced Research WRF model is used to conduct cloud-system-resolving simulations with interactive surface fluxes of sensible heat, latent heat, and of sea salt aerosol, and with a detailed representation of the interaction between aerosol particles and clouds. The mechanisms responsible for the temporal evolution and spatial distribution of the surface heat fluxes in the closed- and open-cell state are investigated and explained. It is found that the horizontal spatial structure of the closed-cell state determines, by entrainment of dry free tropospheric air, the spatial distribution of surface air temperature and water vapor, and, to a lesser degree, of the surface sensible and latent heat flux. The synchronized dynamics of the the open-cell state drives oscillations in surface air temperature, water vapor, and in the surface fluxes of sensible and latent heat, and of sea salt aerosol. Open-cell cloud formation, cloud optical depth and liquid water path, and cloud and rain water path are identified as good predictors of the spatial distribution of surface air temperature and sensible heat flux, but not of surface water vapor and latent heat flux. It is shown that by enhancing the surface sensible heat flux, the open-cell state creates conditions by which it is maintained. While the open-cell state under consideration is not depleted in aerosol, and is insensitive to variations in sea-salt fluxes, it also enhances the sea-salt flux relative to the closed-cell state. In aerosol-depleted conditions, this enhancement may replenish the aerosol needed for cloud formation, and hence contribute to the perpetuation of the open-cell state as well. Spatial homogenization of the surface fluxes is found to have only a small effect on cloud properties in the investigated cases. This indicates that sub-grid scale spatial variability in the surface flux of sensible and latent heat and of sea salt aerosol may not be required in large scale and global models to describe marine boundary layer cellular cloudiness.

  14. Immediate integration of novel meanings: N400 support for an embodied view of language comprehension.

    PubMed

    Chwilla, Dorothee J; Kolk, Herman H J; Vissers, Constance T W M

    2007-12-01

    A substantial part of language understanding depends on our previous experiences, but part of it consists of the creation of new meanings. Such new meanings cannot be retrieved from memory but still have to be constructed. The goals of this article were: first, to explore the nature of new meaning creation, and second, to test abstract symbol theories against embodied theories of meaning. We presented context-setting sentences followed by a test sentence to which ERPs were recorded that described a novel sensible or novel senseless situation (e.g., "The boys searched for branches/bushes [sensible/senseless] with which they went drumming..."). Novel sensible contexts that were not associatively nor semantically related were matched to novel senseless contexts in terms of familiarity and semantic similarity by Latent Semantic Analysis (LSA). Abstract symbol theories like LSA cannot explain facilitation for novel sensible situations, whereas the embodied theory of Glenberg and Robertson [Glenberg, A.M., Robertson, D.A., 2000. Symbol grounding and meaning: A comparison of high-dimensional and embodied theories of meaning. Journal of Memory and Language, 43, 379-401.] in which meaning is grounded in perception and action can account for facilitation. Experiment 1 revealed an N400 effect in a sensibility judgment task. Experiment 2 demonstrated that this effect generalizes to a situation in which participants read for comprehension. Our findings support the following conclusions: First, participants can establish new meanings not stored in memory. Second, this is the first ERP study that shows that N400 is sensitive to new meanings and that these are created immediately - that is, in the same time frame as associative and semantic relations. Third, our N400 effects support embodied theories of meaning and challenge abstract symbol theories that can only discover meaningfulness by consulting stored symbolic knowledge. PMID:17950260

  15. Numerical Simulation of the Effects of Industrial Complexes on Convective Rain Showers.

    Guan, Shucai

    1995-01-01

    An axisymmetric cloud model is used to investigate the evolution of convective clouds and associated rain showers that develop in a calm atmosphere over a large industrial complex with cooling towers. The complex has a continuous release of sensible waste heat, water vapour and anthropogenic cloud condensation nuclei that affect the cloud convection. The simulated convection is in fair agreement with observations for a particular cloud developing over a large oil refinery. Sensitivity experiments are run for two different soundings to quantify how the convection and rainfall depend on the magnitude of the waste energy loss, the area of the source region, the degree of pollution, and other parameters. The Factor Separation Method is applied to quantify the relative contributions of the heating, moisturizing and pollution as individual factors to the convective rain shower, as well as the relative contributions due to the mutual interactions among two or three of these factors. The major findings are the following. (1) Without sustained waste heat input the model convection ceases. The model convection becomes progressively more intense and developed more rain as the rate of total waste energy heat released from the industrial complex is increased. Doubling the total waste energy amount from its control case value causes a 15-fold increase in 3-h rainfall values. However, reducing the control case value of total waste energy release by 20% leads to much weaker convection without rain. (2) The triggering of cumulus clouds is reduced when the waste energy is released as latent heat rather than sensible heat. As the relative contribution of sensible heat increases, so does the intensity of the circulation and the rainfall. (3) The cloud formation depends on the area of the heat source: a wider source tends to delay and to weaken the convection. Specifically, when the area is doubled the simulated cloud appears 2.5 min later and the 3-h rainfall is reduced by 88%. Moreover, the maximum total kinetic energy is reduced by 26%. (4) Model convection is only slightly sensitive to the horizontal distribution of the sensible and latent heat fluxes within the source region. (5) Pollution has only a minor effect on the development of the model cloud and rainfall. Heavy pollution increases accumulated rainfall by 1.8%, whereas light pollution conditions indicate an even smaller rainfall enhancement of 0.2%. (6) For typical magnitudes of sensible heat, latent heat and industrial pollution conditions, the model results suggest that sensible heat is the most important individual contributor for cloud development and rainfall. The contributions arising from interaction between the heat source and the pollution effects are significant for typical atmospheric conditions.

  16. Numerical simulation of Tibetan Plateau heating anomaly influence on westerly jet in spring

    NASA Astrophysics Data System (ADS)

    Xinzhou, Li; Xiaodong, Liu

    2015-11-01

    The intensity and location of the westerly jet (WJ) in the mid-latitudes of the Northern Hemisphere has been closely related to weather and climate changes in Eurasia. In this paper, we analyzed the seasonal and inter-annual variations in the strength and position of the WJ, using the NCEP-DOE reanalysis II (NCEP) data. Spring is the period that the Tibetan Plateau (TP) transits from a cold to a warm condition, and at the same time the WJ weakens and moves northward. Correlation analysis showed that the westerly wind over the north (south) of the TP has a significant positive (negative) correlation with the TP surface temperature in spring during 1979-2013 (99.9% significance level). In spring, surface sensible heat release dominates thermal conditions of the TP, while the contribution of latent heat becomes important in summer. We conducted three numerical experiments to determine the effects of the TP surface sensible heat flux anomaly in spring on the intensity and location of the WJ using the community atmosphere model 5 (CAM5). Experimental results indicated that changing the TP surface sensible heat flux can produce changes in the TP heat sources. When the TP sensible heat flux is switched off (TPSHL), the TP surface has a lower temperature and no longer heats up the middle and upper troposphere, and leads to a maximum cooling of -1.2?C at 200 hPa over the TP with a significance level of 95%. In spring, the abnormal low temperature over the TP caused the WJ to strengthen and move southward compared with the control experiment (CTL), and this results in a westerly (easterly) wind anomaly over the south (north) of the TP with a significance level of 95%. We obtained the opposite conclusion from the comparison of the enhanced TP surface sensible heat flux (TPSHH) with CTL test results. In TPSHL, the WJ is still steadily located near 30?N in May as well as April, i.e., the first northward jump occurs from May to June which is a delay of one month compared to CTL. While in TPSHH, the WJ moves northward approximately 10? of latitude from April to May which is 5? larger than CTL. Thus, the strength and north-south migration of WJ is closely linked to the TP heat source, especially during the spring-summer seasonal transition period, while TP surface temperature increased significantly and showed early signal compared to the surroundings with the global warming. Therefore, considerable attention must be paid to the location and strength of the WJ with respect to the sensible heat flux over the TP.

  17. Food products qualifying for and carrying front-of-pack symbols: a cross-sectional study examining a manufacturer led and a non-profit organization led program

    PubMed Central

    2013-01-01

    Background Concern has been raised that the coexistence of multiple front-of-pack (FOP) nutrition rating systems in a marketplace may mislead consumers into believing that a specific food with a FOP is ‘healthier’ than foods without the symbol. Eleven summary indicator FOP systems are in use in Canada, including one non-profit developed system, the Heart and Stroke Foundation’s Health Check™, and ten manufacturer-developed systems, like Kraft’s Sensible Solutions™. This study evaluated FOP’s potential to mislead consumers by comparing the number of products qualifying to carry a given FOP symbol to the number of products that actually carry the symbol. Methods The nutritional criteria for the Health Check™ and the Sensible Solutions™ systems were applied to a 2010–2011 Canadian national database of packaged food products. The proportion of foods qualifying for a given FOP system was compared to the proportion carrying the symbol using McNemar’s test. Results Criteria were available to categorize 7503 and 3009 of the 10,487 foods in the database under Health Check™ and Sensible Solutions™, respectively. Overall 45% of the foods belonging to a Health Check™ category qualified for Health Check’s™ symbol, while only 7.5% of the foods carried the symbol. Up to 79.1% of the foods belonging to a Sensible Solutions™, category qualified for Sensible Solutions’s™ symbol while only 4.1% of the foods carried the symbol. The level of agreement between products qualifying for and carrying FOP systems was poor to moderate in the majority of food categories for both systems. More than 75% of the products in 24 of the 85 Health Check™ subcategories and 9 of 11 Sensible Solution™ categories/subcategories qualified for their respective symbols based on their nutritional composition. Conclusions FOP systems as they are currently applied are not, in most instances, a useful guide to identifying healthier food products in the supermarket as many more products qualify for these systems than the number of products actually displaying these symbols on FOP, and the level of agreement between qualifying and carrying products is poor to moderate. The adoption of a single, standardized FOP system would assure consumers that all products meeting certain nutritional standards are designated by the symbol. PMID:24034717

  18. Seasonal Contrasts in the Surface Energy Balance of the Sahel

    2009-03-14

    Over most of the world ocean, heating of the surface by sunlight is balanced predominately by evaporative cooling. Even over land, moisture for evaporation is available from vegetation or the soil reservoir. However, at the ARM Mobile Facility in Niamey, Niger, soil moisture is so depleted that evaporation makes a significant contribution to the surface energy balance only at the height of the rainy season, when precipitation has replenished the soil reservoir. Using observations at the Mobile Facility from late 2005 to early 2007, we describe how the surface balances radiative forcing. How the surface compensates time-averaged solar heating varies with seasonal changes in atmospheric water vapor, which modulates the greenhouse effect and the ability of the surface to radiate thermal energy directly to space. During the dry season, sunlight is balanced mainly by longwave radiation and the turbulent flux of sensible heat. The ability of longwave radiation to cool the surface drops after the onset of the West African summer monsoon, when moist, oceanic air flows onshore, increasing local column moisture and atmospheric opacity at these wavelengths. After the monsoon onset, but prior to significant rainfall, solar heating is compensated mainly by the sensible heat flux. During the rainy season, the magnitude of evaporation is initially controlled by the supply of moisture from precipitation. However, by the height of the rainy season, sufficient precipitation has accumulated at the surface that evaporation is related to the flux demanded by solar radiation, and radiative forcing of the surface is balanced comparably by the latent, sensible, and longwave fluxes. Radiative forcing of the surface also varies on a subseasonal time scale due to fluctuations in water vapor, clouds, and aerosol concentration. Except at the height of the rainy season, subseasonal forcing is balanced mainly by sensible heating and longwave anomalies. The efficacy of the sensible heat flux depends upon a positive feedback, where forcing changes mixing within the boundary layer and amplifies the sensible heating anomaly. How the surface responds to radiative forcing is fundamental to the climate response to dust and carbonaceous aerosols.

    2015-07-02

    The atmospheric conditions associated with the rare Weddell Sea open ocean polynya are investigated. The polynya has not been seen since 1976, so data on the event is scarce. The CESM high resolution model is used to investigate multiple atmospheric variables. We analyze three years of polynyas, which are also compared to three years without a polynya. The surface temperature, sensible heat flux, latent heat flux, humidity, average wind speed, precipitation, longwave flux, and shortwave flux all increased over the polynya. The sensible heat flux had a higher magnitude than the latent heat flux because conduction and convection were the primary drivers of heat flux. A combination of increased latent heat flux and humidity led to an increase in precipitation. Increased longwave downwelling flux over the polynya indicated the presence of clouds over the polynya. Lastly, the sea level pressure was consistently lower over the polynya because of the presence of a thermal low generated by thermally driven convective updrafts.

    Several methods for estimating surface energy balance components over a vegetated surface are compared. These include Penman-Monteith, Deardorff, and multilayer canopy (CANWHT) models for evaporation. Measurements taken during the 1991 DOE-sponsored Boardman Area Regional Flux Experiment over a well-irrigated, closed wheat canopy are used in the comparison. The relative performance of each model is then evaluated. It is found that the Penman-Monteith approach using a simple parameterization for stomatal conductance performs best for evaporation flux. The Deardorff model is found to have the best relative performance for sensible heat, while the CANWHT model gives the best results for net radiation and soil heat flux. The Priestley-Taylor model for evaporation and a resistance-analog equation for sensible heat flux are also tested. 35 refs., 9 figs., 4 tabs.

    A 'resistance model' and a mass transport model for estimating evapotranspiration (ET) were tested on large fields of naturally subirrigated alfalfa. Both models make use of crop canopy temperature data. Temperature data were obtained with an IR thermometer and with leaf thermocouples. A Bowen ratio-energy balance (BREB) model, adjusted to account for underestimation of ET during periods of strong sensible heat advection, was used as the standard against which the resistance and mass transport models were compared. Daily estimates by the resistance model were within 10% of estimates made by the BREB model. Daily estimates by the mass transport model did not agree quite as well. Performance was good on clear and cloudy days and also during periods of non-advection and strong advection of sensible heat. The performance of the mass transport and resistance models was less satisfactory for estimation of fluxes of latent heat for short term periods. Both models tended to overestimate at low LE fluxes.

    Simulations of the thermally induced breeze involved with a relatively narrow, elongated water body is presented in conjunction with evaluations of sensible heat fluxes in a stable marine atmospheric surface layer. The effect of the water surface temperature and of the large-scale synoptic winds on the development of surface flows over the water is examined. As implied by the sensible heat flux patterns, the simulation results reveal the following trends: (1) when the synoptic flow is absent or light, the induced surface breeze is not affected noticeably by a reduction of the water surface temperature; and (2) for stronger synoptic flow, the resultant surface flow may be significantly affected by the water surface temperature.

    Forty-six equines were observed during routine commercial slaughter in an abattoir. The animals were shot once with a .22 calibre long rifle with hollow point rounds. Indicators of sensibility/insensibility were evaluated immediately after the shot (prior to exsanguination) and the resulting pathophysiology of free-bullet injury was assessed. All animals were rendered immediately insensible, with only one pony showing signs of a shallow depth of concussion, with an intermittently positive palpebral reflex but no other signs of brainstem function. All animals (100%) had some degree of damage to the structures of the brainstem or lobes of the cerebrums, while 41 (89%) had damage to the thalamus/hypothalamus. The bullet in one pony missed the brain but still caused mild damage to the thalamus, midbrain, pons and cerebellum, this animal had no signs of sensibility. The findings confirm that free-bullet shooting is an effective dispatch method for horses and ponies. PMID:26093383

    The role of medium-scale waves on three dynamic aspects of the Southern-Hemisphere general circulation is examined using data generated by the FGGE analyses of the ECMWF. The momentum and sensible heat transports by the medium-scale waves are discussed. The effects of medium-scale waves on atmospheric circulation of the Southern Hemisphere during the summer, in particular the vacillation of atmospheric energetics, are investigated. The horizontal and vertical structures and the transport properties of this wave regime and their relation to downstream development in the Southern Hemisphere are analyzed. It is observed that medium-scale waves supply about a half of the total eddy transport of sensible heat and momentum; the wave regime contributes to the time average of various energy contents and energetic components of atmospheric motion during the southern summer; and the wave regime is amplified during the developing stages of downstream development.

    Studies concerning mesoscale topographical effects on Martian flows examined low-level jets in the near equatorial latitudes and the dynamical intensification of flow by steep terrain. Continuation of work from previous years included evaluating the dissipation of cold air mass outbreaks due to enhanced sensible heat flux, further sensitivity and scaling evaluations for generalization of the characteristics of Martian mesoscale circulation caused by horizontal sensible heat-flux gradients, and evaluations of the significance that non-uniform surface would have on enhancing the polar CO2 ice sublimation during the spring. The sensitivity of maximum and minimum atmospheric temperatures to changes in wind speed, surface albedo, and deep soil temperature was investigated.

Among these sera, 33 samples related to non-treated patients at different stages of infection, and 80 samples to treated patients. The results point out a light sensibility of the IgM-SPHA in primary lues. The IgM-EIA test has performed a good specificity, but displayed a sensibility lower to the 19S IgM FTA-ABS, which proved the best of tests. About the cases of treated lues at different stages, in 23 samples with VDRL negative has been found no positivity at three tests used, while in 49 samples with VDRL positive 8 are resulted positive at 19S IgM FTA-ABS.

    The generation of available potential energy (APE) was evaluated in the warm sector of an extratropical cyclone containing intense convective activity. Mesoscale rawinsonde data from AVE-SESAME '79 was employed. Parametrization techniques were used for latent and sensible heating components, and variations for the Kuo scheme provided convective latent heat release. Radiative transfer models were used to obtain estimates of infrared and solar processes. The results indicated that solar heating was greater than IR cooling near midday. An extensive low-level cloud deck was the most radiatively active area. Negative generation of APE occurred during most of the period for the SESAME domain as a whole. The leading contributor was convective latent heating located primarily in regions of negative efficiency. Infrared cooling was the only component to consistently produce positive generation. Sensible heating provided an important sink of APE in the low levels during the afternoon.

    Using a six year data set of eddy covariance flux measurements of sensible and latent heat, soil heat flux, net radiation, above-ground phytomass and meteorological driving forces energy partitioning was investigated at a temperate mountain grassland managed as a hay meadow in the Stubai Valley (Austria). The main findings of the study were: (i) Energy partitioning was dominated by latent heat, followed by sensible heat and the soil heat flux; (ii) When compared to standard environmental forcings, the amount of green plant matter, which due to three cuts varied considerably during the vegetation period, explained similar, and partially larger, fractions of the variability in energy partitioning; (iii) There were little, if any, indications of water stress effects on energy partitioning, despite reductions in soil water availability in combination with high evaporative demand, e.g. during the summer drought of 2003.

  9. Land surface energy partitioning revisited: A novel approach based on single depth soil measurement

    The partitioning of solar energy into sensible, latent, and ground heat fluxes over the land surface is responsible for changes of state variables in the soil-atmosphere system. Recent research enables the reconstruction of the land surface temperature and ground heat flux using Green's function approach, as well as the estimate of the distribution of available energy into latent and sensible heat fluxes based on linear stability analysis. Combining the Green's function approach and linear stability analysis, we propose a new physically based numerical procedure to estimate the land surface energy partitioning in this paper. The new method is capable of predicting all surface energy budgets using a single depth soil measurement; the model reliability is evaluated with comparisons to flux tower measurements. The results of this study deepen our insight into the implicit link between surface energy partition and subsurface soil dynamics and how the link can be employed to related research areas.

    The primary objectives of the 1985 study were to test the feasibility of using radio frequency receivers to collect data from automated weather stations and to evaluate the use of the data collected by the automated weather stations for modeling the fluxes of latent heat, sensible heat, and radiation over wheat. The model Cupid was used to calculate these fluxes which were compared with fluxes of these entities measured using micrometeorological techniques. The primary objectives of the 1986 study were to measure and model reflected and emitted radiation streams at a few locations within the First International Satellite Land-Surface Climatology Project Field Experiment (FIFE) site and to compare modeled and measured latent heat and sensible heat fluxes from the prairie vegetation.

    The energy and radiation balance components were determined over three grass surfaces, located on the Streletskaya steppe during July 1991. The Bowen ratio energy balance method was used to determine the sensible and latent heat flux densities using six computer controlled systems. A total of 126 variables were sampled, including global, diffuse, and reflected solar radiation, long wave radiation (up and down), net radiation, photosynthetically active radiation above and below the vegetation, infrared surface temperatues, soil temperature and heat flow, air temperature and vapor pressure at two levels, wind speed and direction, and precipitation. The ranking of the sites from greatest to smallest for net radiation and latent heat flux density were preserve, mowed in 1990, and mowed in 1991. The ranking of the sites from greatest to smallest for sensible heat flux density were mowed in 1990, mowed in 1991, and preserve.

    In 1748, in his acte de ballet Pygmalion, composer and music theorist Jean-Philippe Rameau arranged the Paris Opéra orchestra to play "nature's chord," harmonies that reproduced the overtones an expert ear could detect in every natural musical vibrating body. The following year Rameau presented his music theory to the French Royal Academy of Sciences for their endorsement. Disillusionment with the promise of Cartesian mechanics as a source of a unified understanding of nature opened up the possibility that matter might have properties beyond extension and motion, such as aversion, desire, and memory. Speculations about this material sensibility also coincided with increasing claims about the authority of spontaneous emotion and feeling. The experience of music at the opera was a significant resource for claims about the cultural authority of sensibility.

    The machine sensible version of the AE-8 electron model environment was completed in December 1983. It has been sent to users on the model environment distribution list and is made available to new users by the National Space Science Data Center (NSSDC). AE-8 is the last in a series of terrestrial trapped radiation models that includes eight proton and eight electron versions. With the exception of AE-8, all these models were documented in formal reports as well as being available in a machine sensible form. The purpose of this report is to complete the documentation, finally, for AE-8 so that users can understand its construction and see the comparison of the model with the new data used, as well as with the AE-4 model.

  14. The meridional variation of the eddy heat fluxes by baroclinic waves and their parameterization

    NASA Technical Reports Server (NTRS)

    Stone, P. H.

    1974-01-01

    The meridional and vertical eddy fluxes of sensible heat produced by small-amplitude growing baroclinic waves are calculated using solutions to the two-level model with horizontal shear in the mean flow. The results show that the fluxes are primarily dependent on the local baroclinicity, i.e., the local value of the isentropic slopes in the mean state. Where the slope exceeds the critical value, the transports are poleward and upward; where the slope is less than the critical value, the transports are equatorward and downward. These results are used to improve an earlier parameterization of the tropospheric eddy fluxes of sensible heat based on Eady's model. Comparisons with observations show that the improved parameterization reproduces the observed magnitude and sign of the eddy fluxes and their vertical variations and seasonal changes, but the maximum in the poleward flux is too near the equator.

    2005-01-01

    This study focuses on the effect of Soil Hydraulic Property (SHP) selection on modeled surface fluxes following a rain storm in a semi-arid environment. SHPs are often defined based on a Soil Texture Class (STC). To examine the effectiveness of this approach, the Noah land surface model was run with each of 1306 soils in a large SHP database. Within most STCs, the outputs have a range of 350 W/m2 for latent and sensible heat fluxes, and 8K for surface temperature. The average difference between STC median values is only 100 W/m2 for latent and sensible heat. It is concluded that STC explains 5-15% of the variance in model outputs and should not be used to determine SHPs.

    2015-01-01

    This article describes electric arc furnace (EAF) off-gas enthalpy models developed at Oak Ridge National Laboratory (ORNL) to calculate overall heat availability (sensible and chemical enthalpy) and recoverable heat values (steam or power generation potential) for existing EAF operations and to test ORNL s new EAF waste heat recovery (WHR) concepts. ORNL s new EAF WHR concepts are: Regenerative Drop-out Box System and Fluidized Bed System. The two EAF off-gas enthalpy models described in this paper are: 1.Overall Waste Heat Recovery Model that calculates total heat availability in off-gases of existing EAF operations 2.Regenerative Drop-out Box System Model in which hot EAF off-gases alternately pass through one of two refractory heat sinks that store heat and then transfer it to another gaseous medium These models calculate the sensible and chemical enthalpy of EAF off-gases based on the off-gas chemical composition, temperature, and mass flow rate during tap to tap time, and variations in those parameters in terms of actual values over time. The models provide heat transfer analysis for the aforementioned concepts to confirm the overall system and major component sizing (preliminary) to assess the practicality of the systems. Real-time EAF off-gas composition (e.g., CO, CO2, H2, and H2O), volume flow, and temperature data from one EAF operation was used to test the validity and accuracy of the modeling work. The EAF off-gas data was used to calculate the sensible and chemical enthalpy of the EAF off-gases to generate steam and power. The article provides detailed results from the modeling work that are important to the success of ORNL s EAF WHR project. The EAF WHR project aims to develop and test new concepts and materials that allow cost-effective recovery of sensible and chemical heat from high-temperature gases discharged from EAFs.

  19. Air-sea interaction and formation of the Asian summer monsoon onset vortex over the Bay of Bengal

    2012-01-01

    In spring over the southern Bay of Bengal (BOB), a vortex commonly develops, followed by the Asian summer monsoon onset. An analysis of relevant data and a case study reveals that the BOB monsoon onset vortex is formed as a consequence of air-sea interaction over BOB, which is modulated by Tibetan Plateau forcing and the land-sea thermal contrast over the South Asian area during the spring season. Tibetan Plateau forcing in spring generates a prevailing cold northwesterly over India in the lower troposphere. Strong surface sensible heating is then released, forming a prominent surface cyclone with a strong southwesterly along the coastal ocean in northwestern BOB. This southwesterly induces a local offshore current and upwelling, resulting in cold sea surface temperatures (SSTs). The southwesterly, together with the near-equatorial westerly, also results in a surface anticyclone with descending air over most of BOB and a cyclone with ascending air over the southern part of BOB. In the eastern part of central BOB, where sky is clear, surface wind is weak, and ocean mixed layer is shallow, intense solar radiation and low energy loss due to weak surface latent and sensible heat fluxes act onto a thin ocean layer, resulting in the development of a unique BOB warm pool in spring. Near the surface, water vapor is transferred from northern BOB and other regions to southeastern BOB, where surface sensible heating is relatively high. The atmospheric available potential energy is generated and converted to kinetic energy, thereby resulting in vortex formation. The vortex then intensifies and moves northward, where SST is higher and surface sensible heating is stronger. Meanwhile, the zonal-mean kinetic energy is converted to eddy kinetic energy in the area east of the vortex, and the vortex turns eastward. Eventually, southwesterly sweeps over eastern BOB and merges with the subtropical westerly, leading to the onset of the Asian summer monsoon.

  9. Analysis of atmospheric turbulence in the upper layers of sea fog

    NASA Astrophysics Data System (ADS)

    2015-05-01

    Atmospheric turbulence plays a vital role in the formation and dissipation of fog. However, studies of such turbulence are typically limited to observations with ultrasonic anemometers less than 100 m above ground. Thus, the turbulence characteristics of upper fog layers are poorly known. In this paper, we present 4-layers of data, measured by ultrasonic anemometers on a wind tower about 400 m above the sea surface; we use these data to characterize atmospheric turbulence atop a heavy sea fog. Large differences in turbulence during the sea fog episode were recorded. Results showed that the kinetic energy, momentum flux, and sensible heat flux of turbulence increased rapidly during the onset of fog. After onset, high turbulence was observed within the uppermost fog layer. As long as this turbulence did not exceed a critical threshold, it was crucial to enhancing the cooling rate, and maintaining the fog. Vertical momentum flux and sensible heat flux generated by this turbulence weakened wind speed and decreased air temperature during the fog. Towards the end of the fog episode, the vertical distribution of sensible heat flux reversed, contributing to a downward momentum flux in all upper layers. Spatial and temporal scales of the turbulence eddy were greater before and after the fog, than during the fog episode. Turbulence energy was greatest in upper levels, around 430 m and 450 m above mean sea level (AMSL), than in lower levels of the fog (390 m and 410 m AMSL); turbulence energy peaked along the mean wind direction. Our results show that the status of turbulence was complicated within the fog; turbulence caused fluxes of momentum and sensible heat atop the fog layer, affecting the underlying fog by decreasing or increasing average wind speed, as well as promoting or demoting air temperature stratification.

    Independent measurements of the major energy balance flux components are not often consistent with the principle of conservation of energy. This is referred to as a lack of closure of the surface energy balance. Most results in the literature have shown the sum of sensible and latent heat fluxes measured by eddy covariance to be less than the difference between net radiation and soil heat fluxes. This under-measurement of sensible and latent heat fluxes by eddy-covariance instruments has occurred in numerous field experiments and among many different manufacturers of instruments. Four eddy-covariance systems consisting of the same models of instruments were set up side-by-side during the Southern Great Plains 1997 Hydrology Experiment and all systems under-measured fluxes by similar amounts. One of these eddy-covariance systems was collocated with three other types of eddy-covariance systems at different sites; all of these systems under-measured the sensible and latent-heat fluxes. The net radiometers and soil heat flux plates used in conjunction with the eddy-covariance systems were calibrated independently and measurements of net radiation and soil heat flux showed little scatter for various sites. The 10% absolute uncertainty in available energy measurements was considerably smaller than the systematic closure problem in the surface energy budget, which varied from 10 to 30%. When available-energy measurement errors are known and modest, eddy-covariance measurements of sensible and latent heat fluxes should be adjusted for closure. Although the preferred method of energy balance closure is to maintain the Bowen-ratio, the method for obtaining closure appears to be less important than assuring that eddy-covariance measurements are consistent with conservation of energy. Based on numerous measurements over a sorghum canopy, carbon dioxide fluxes, which are measured by eddy covariance, are underestimated by the same factor as eddy covariance evaporation measurements when energy balance closure is not achieved.

    An approach to switching between different patterns of light beams transmitted through the woodpile photonic crystals filled with liquid crystals is proposed. The phase transition between the nematic and isotropic liquid crystal states leads to an observable variation of the spatial pattern transmitted through the photonic structure. The transmission profiles in the nematic phase also show polarization sensibility due to refractive index dependence on the field polarization. The experimental results are consistent with a numerical calculation by Finite Difference Time Domain method.

The radiometric scalar roughness is considered and found to be related to solar elevation and canopy height, although the regional sensible heat flux derived by the similarity theory analysis agrees with measured flux values.
