  1. A Dictionary of Sensibility

    NSDL National Science Digital Library

    The language of sensibility in eighteenth-century Europe encompassed a number of interconnected vocabularies and offered manifold and varied meanings to terms such as virtue, imagination, sublime, character, and community. This online dictionary, hosted by the University of Virginia English Department, allows users to explore these vocabularies and meanings through excerpts from primary texts of sensibility. The Dictionary offers a list of terms (currently 24) pertaining to sensibility, each of which links to an introduction and a collection of annotated relevant excerpts. Source and critical bibliographies are also provided. Readers are invite to contribute to the Dictionary, and submission details are included at the site.

  2. Sensibility and clinical understanding.

    PubMed

    Nortvedt, Per

    2008-06-01

    This paper argues that there is a dimension of human consciousness which allows for a pre-intentional and non-cognitive intuition of sensibility. A sensibility which allows for the vulnerability of the human other is by nature characterized by passivity and receptivity. Moreover, sensibility invokes the significance of relating to the human other in an affective way of being touched by his or her pain and suffering. This capacity of being distressed by the distress of another person opens up for ethical responsibility and even in a fundamental sense is a presupposition for full-fledged clinical knowledge in medical care and health care.

  4. 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.

    Norrsell, U; Eliasson, B; Frizell, M; Wallin, B G; Wesslau, C; Olausson, H

    2001-11-01

    Five different procedures used to diagnose neuropathy were compared in a "blind" study with diabetic patients. The aim was to evaluate tests of tactile directional sensibility. Three matched groups were examined, two groups with type I diabetes, either with or without suspected neuropathy, and one of healthy controls. Testing consisted of: (1) examination by a specialist in neurology, (2) electrophysiologic measurement of nerve conduction velocity and determination of cool sensitivity, and (3) determination of directional sensibility in two stages, with categorical and quantitative techniques. Abnormal test results were obtained for both groups of diabetic patients. Quantitatively measured directional sensibility had the highest sensitivity (89%) and specificity (85%) when calculated for patients who had received a diagnosis of neuropathy from the neurologist, despite one case of abnormal directional sensibility among the healthy controls. Conduction velocity testing was almost comparably sensitive (80%) and cool sensitivity, comparably specific (85%) when calculated in the same manner. PMID:11745952

  14. Latent and sensible heat flux estimated from ERS-1 data

    NASA Technical Reports Server (NTRS)

    Iacobellis, S. F.; Gautier, C.

    1993-01-01

    Two issues regarding surface latent and sensible heat flux are addressed: its value in low wind speed conditions over the tropical oceans,and its determination solely from satellite observations. The investigation is performed with an oceanic mixed layer model operated in an 'inverse' mode. The 'normal' model is forced with the surface heat and radiative fluxes and produces the SST evolution, whereas the 'inverse' model produces the latent sensible heat flux given the SST and surface radiative flux as input. The results indicate that at low wind speeds there exists a minimum latent sensible heat flux of about 80 to 100 W/sq m. Sensitivity studies show that the latent sensible heat flux is very sensitive to random errors in the forcing SST time series. The implications of this strong sensitivity in regards to the use of satellite measurements to supply the forcing SST are discussed.

    1988-01-01

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

    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.

    1996-05-01

    In semi-arid regions, the contribution of fluxes from the bare soil to the total fluxes of heat, water vapour and momentum is considerable. A simple technique is presented to estimate the sensible heat from the soil by using Nusselt numbers. This technique has been tested with measurements collected during the EFEDA-2 experiments in Spain under mixed convective and forced convective conditions. The results obtained with the Nusselt number technique agree well with the sensible heat flux measured by the eddy-correlation technique.

    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.

    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 was conducted through the combined use of PATRAN, SINDA, TRASYS, and NASTRAN software packages.

  9. A comparison of five tests for determining hand sensibility.

    Patel, M R; Bassini, L

    1999-10-01

    Three hundred seventeen normal fingers and 612 fingers in 153 hands with carpal tunnel syndrome were tested for sensibility using the Weinstein Enhanced Sensory Test (WEST) with calibrated monofilaments, by static two-point discrimination (s2PD) and moving two-point discrimination (m2PD), using the Disk-Criminator, and by Strauch's ten test. Equivalent Semmes-Weinstein monofilament (SWM) test values were also determined as a gold standard for comparison. With both the WEST and SWM test values, the norms for interpretation have an unacceptably wide latitude because of the use of an ordinal scale of increasingly unequal intervals. With the WEST and Disk-Criminator tests, some cases of early sensory loss were missed. The SWM test apparatus, although producing relatively reliable values, is not easily portable, and its use is time-consuming in a busy office; the WEST device is prohibitively expensive. The ten test is rapid, simple, and sensitive in evaluation. It measures sensibility on a continuous analog scale, and allows for multiple points of testing in the hand, with good inter- and intra-examiner reliability. It is accurate in detecting very early loss of sensibility. In addition, the ten test requires no instrumentation. PMID:10566581

    Stearns, Charles R.; Weidner, George A.

    1993-01-01

    The assumption has been made that the net annual contribution of water by the processes of deposition and sublimation to the Antarctic Ice Sheet is zero. The U.S. Antarctic Program started installing reliable automatic weather stations on the Antarctic Continent in 1980. The initial units were equipped to measure wind speed, wind direction, air pressure, and air temperature. During the 1983-1984 field season in Antarctica, three units were installed that measured a vertical air temperature difference between the nominal heights of 0.5 m and 3.0 m and relative humidity at a nominal height of 3 m. The measurements of the vertical air temperature difference and the relative humidity are the minimum required to estimate the sensible and latent heat fluxes to the air, while not exceeding the available energy requirements for the weather stations. The estimates of the net annual sublimation and deposition on the Ross Ice Shelf amount to 20 to 80 percent of the annual accumulation. We conclude that the assumption that annual sublimation and deposition are zero is not valid under Antarctic conditions.

  14. Anterior insular cortex mediates bodily sensibility and social anxiety.

    PubMed

    2013-03-01

    Studies in psychiatry and cognitive neuroscience have reported an important relationship between individual interoceptive accuracy and anxiety level. This indicates that greater attention to one's bodily state may contribute to the development of intense negative emotions and anxiety disorders. We hypothesized that reactivity in the anterior insular cortex underlies the intensity of interoceptive awareness and anxiety. To elucidate this triadic mechanism, we conducted functional magnetic resonance imaging (fMRI) and mediation analyses to examine the relationship between emotional disposition and activation in the anterior insular cortex while participants evaluated their own emotional and bodily states. Our results indicated that right anterior insular activation was positively correlated with individual levels of social anxiety and neuroticism and negatively correlated with agreeableness and extraversion. The results of the mediation analyses revealed that activity in the right anterior insula mediated the activity of neural correlates of interoceptive sensibility and social fear. Our findings suggest that attention to interoceptive sensation affects personality traits through how we feel emotion subjectively in various situations. PMID:22977199

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

    PubMed

    Thompson, Margo Hobbs

    2008-01-01

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

    2009-03-01

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

    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.

    Commercial remote sensing uses satellite imagery to provide valuable information about the planet's features. By capturing light reflected from the Earth's surface with cameras or sensor systems, usually mounted on an orbiting satellite, data is obtained for business enterprises with an interest in land feature distribution. Remote sensing is practical when applied to large-area coverage, such as agricultural monitoring, regional mapping, environmental assessment, and infrastructure planning. For example, cellular service providers use satellite imagery to select the most ideal location for a communication tower. Crowsey Incorporated has the ability to use remote sensing capabilities to conduct spatial geographic visualizations and other remote-sensing services. Presently, the company has found a demand for these services in the area of litigation support. By using spatial information and analyses, Crowsey helps litigators understand and visualize complex issues and then to communicate a clear argument, with complete indisputable evidence. Crowsey Incorporated is a proud partner in NASA's Mississippi Space Commerce Initiative, with research offices at the John C. Stennis Space Center.

  10. Momentum and Sensible Heat Exchange in an Ice-Free Arctic Fjord

    NASA Astrophysics Data System (ADS)

    Kilpeläinen, Tiina; Sjöblom, Anna

    2010-01-01

    Momentum and sensible heat exchange are studied in an Arctic fjord system in Spitsbergen, Svalbard (Norway), based on tower measurements taken in January-June 2008. Due to ice-free conditions, the surface layer was unstable for most of the time, occasionally very unstable. The shape of the fjord and the surrounding topography have a large influence on the wind field. Low frequency eddies are mainly responsible for occasionally large crosswind momentum transfer that, together with upward momentum transfer (occurring in 9% of the data), invalidate conventional stability and scaling parameters. When the flow is along the fjord with moderate or high wind speeds, the Monin-Obukhov similarity theory is applicable. However, the momentum and the sensible heat exchange in the fjord system differs from the exchange taking place over the open ocean, mainly due to topographic effects.

    Traditional practice in residential, air-cooled cooling equipment has been to select equipment based solely on the total cooling capacity of the air conditioner. This methodology was widely accepted back in 1960 when the All-Industry Heat Gain Procedure was introduced. This procedure was based on the experience in five research houses built between 1940 and 1957 at the University of Illinois. During the ensuing 30 years, both equipment and house construction technology has changed substantially, so much so that the total cooling method cannot be successfully applied to a growing number of installations with adequate confidence. This paper describes a methodology to select residential equipment based on an estimate of both sensible and latent cooling loads and equipment sensible and latent performance.

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

    Remote sensing (RS) has been recognized as the most feasible means to provide spatially distributed regional evapotranspiration (ET). However, classical RS flux algorithms (SEBS, S-SEBI, SEBAL, etc.) can hardly be used with coarser resolution RS data from sensors like MODIS or AVHRR for no consideration of surface heterogeneity in mixed pixels even they are suitable for assessing the surface fluxes with high resolution RS data.A new model named FAFH is developed in this study to enhance the accuracy of flux estimation in mixed pixels based on high resolution landcover classification data. The area fraction and relative sensible heat fraction of each heterogeneous land use type calculated within coarse resolution pixels are calculated firstly, and then used for the weighted average of modified sensible heat. The study is carried out in the core agricultural land of Zhangye, the middle reaches of Heihe river based on the flux and landcover classification product of HJ-1B in our earlier work. The result indicates that FAFH increases the accuracy of sensible heat by 5% absolutely, 10.64% relatively in the whole research area.

    Measurements of sensible heat flux, radiometric surface temperature, air temperature, and wind speed made at eight semiarid rangeland sites were used to investigate the sensible heat flux-aerodynamic resistance relationship. The individual sites covered a wide range of vegetation (0.1-4 m tall) and cover (3%-95% bare soil) conditions. Mean values of k/B, a quantity related to the resistance of heat versus momentum transfer at the surface, for the individual sites varied between 3.5 and 12.5. A preliminary test of the utility of an excess resistance based on the mean value of k/B showed that the difference between the mean estimated and measured sensible heat fluxes varied +/- 60 W/sq m for the eight semiarid sites. For the eight sites the values of k/B were plotted against the roughness Reynolds number. The plot showed considerable scatter with values ranging between and beyond the theoretical curves for bluff rough and permeable rough surfaces.

  15. Development and Analysis of a Global, Terrestrial Sensible Heat Flux Dataset

    2014-12-01

    Energy exchange between the atmosphere and the Earth's surface is manifested through sensible and latent heat turbulent fluxes, with their mean states and variability central features of regional climate. Estimating these fluxes using global data sets and understanding their variability is still unresolved but is a central focus of WCRP's Global Energy and Water Exchange (GEWEX) Data Assessment Panel (GDAP) through the LandFlux activities. In recent years, LandFlux has made progress developing terrestrial latent heat data sets, but the progress developing a consistent, multi-decadal sensible heat product has been limited by challenges such as the poorly measured surface temperature gradient and the parameterization of the aerodynamic resistance. While wind and surface roughness control the turbulent transfer of heat, stable boundary layer conditions offer additional challenges. GDAP strives for satellite and input consistency across the data sets. For the sensible heat data product, this manifests itself primarily in the land surface temperature (LST) (being consistent with the High Resolution Infrared Radiation Sounder (HIRS) observations). Due to its sparse coverage (swath and cloud-contamination), a HIRS-consistent, hourly, global, 0.5 degree resolution LST dataset for clear and cloudy conditions (1979 to 2009) is developed through merging of the NCEP Climate Forecast System Reanalysis (CFSR) estimates with HIRS retrievals, which are validated against the Baseline Surface Radiation Network (BSRN)-based LST. The surface air temperature is estimated by adding the temperature gradient from CFSR to the HIRS-consistent LST data product, and validated against ~10,000 surface stations. The aerodynamic resistance is based on optimized values at 70 global FluxNet towers and extended globally through an objective analysis with land cover and climate covariates. These products are used to form a global terrestrial, hourly, 0.5 degree spatial resolution sensible heat dataset. The spatial, seasonal, and inter-annual variability of the dataset is presented. The sensible heat flux is combined with the LandFlux latent heat estimates and the surface radiation budget ver. 3 (SRB-3) to assess the space-time variability in the combined surface fluxes (e.g. Bowen ratio) as well as budget closure.

    One of the goals of the recent CBLAST-hurricane experiment was to measure turbulent fluxes in the high wind conditions of the hurricane boundary layer. During the experiment 6 low level flights into hurricanes Fabian and Isabel were made with NOAA's P3 Hurricane Hunter aircraft. While the momentum and latent heat flux results have been reported elsewhere, here we present the results for sensible heat flux. Up to the highest 10m winds measured (30m/s), the Stanton number remains constant, and in the range of previous lower wind estimates. The impact of this on hurricane enthalpy flux calculations is discussed.

    2013-12-01

    Long-term measurements of sensible and latent heat and carbon dioxide fluxes were performed over a boreal lake in northern American using the direct micrometeorological eddy covariance (EC) technique. Two permanent EC flux stations in western Lake Erie - Crib (41.7167N, 83.2667W, nearest distance from shore is 4.5 km) and Light (41.8314N, 83.2006W, nearest distance from shore > 12 km) sites have been operating since September, 2011. In 2012, in both sites, the sensible heat flux had its minimum in the afternoon (15:00-17:00) and peaked in the early morning (7:00-9:00) in August-November, varied from -4 W m-2 to +30 W m-2. The diurnal amplitude of H was largest in spring and in early fall (30 W m-2 in September) whereas it was smaller in July and August (20 W m-2). The latent heat flux had obvious seasonal pattern in both sites with higher values in the summer, while it did not show obvious daily courses, even did not have the day and night variation in both sites, only one trend from June to October was higher at night than during the daytime in Light site. The maximum latent heat of ~180 W m-2 in summer whereas the minimum -10 W m-2 in winter were observed. The latent heat flux dominated clearly over the sensible heat in spring and summer; that is, the Bowen ratio was less than 1 and most of the energy absorbed by the water was consumed in terms of evapotranspiration. A lookup table method was performed data gap-filling in our aquatic ecosystems in order to obtain the continuously daily, monthly and yearly carbon and water budgets. In 2012, for the annual cumulative total, the evapotranspiration was 820 and 700 mm (about 2000 and 1700 MJ m-2) in Crib and Light sites, respectively, comparing with the annual rainfall of 700 mm. The annual sensible heat was 480 and 300 MJ m-2 in Crib and Light sites, respectively. And there were four and five CO2 uptake months in Crib and Light sites, respectively. The maximum CO2 uptake month was in July in both sites, with -28 and -72 gC m-2 month-1 in Crib and Light site, respectively. For the annual cumulative total, both of the two sites showed as carbon neutral or a small sink with magnitudes of 25 and -12 g C m-2 in Crib and Light sites, respectively.

    The interannual variability in water vapour and sensible heat fluxes over beech forest in Denmark is analysed. A time-series from seven years (half hourly values) are investigated in regard to extremes and the interannual variability at daily and monthly time-scales. The fluxes are measured by the eddy correlation technique from a tall mast in the center of the forest. The experimental site is part of the CARBO-EUROFLUX network and observations include precipitation, soil water, CO2, temperature, humidity, solar radiation and plant parameters. In the current study focus is on the water balance. A comparison between the water balance components, CO2 and environmental parameters is undertaken. The results are part of EO-FLUX-BUDGET project (http://www.geogr.ku.dk/projects/eoflux/) aiming for spatial and temporal predictions of the water vapour, sensible heat and CO2 balance over the island Zealand (7.200 km2) in Denmark based on satellite Earth Observation data at high resolution. The validation part is based on the in-situ heat and water vapour flux observations presented here.

    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.

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

    PubMed

    Kim, W Y; Kurmar, S

    2015-07-15

    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

    Verburg, Piet; Antenucci, Jason P.

    2010-06-01

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

  5. 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.

    2015-04-01

    Surface turbulent heat fluxes are critically important in climate model experiments, since they represent a language of communication of the ocean and atmosphere. Interannual variability of surface turbulent heat fluxes is believed to be the major contributor to the changes in the ocean surface heat balance, at least in mid latitudes. Being relatively well assessed and validated in reanalyses, surface turbulent heat fluxes always were of a lesser attention in diagnostics of climate model experiments. We analysed interannual variability of sensible and latent heat fluxes in historical climate simulations with several CMIP5 models. Variability in surface turbulent sensible and latent heat fluxes in model simulations has been analysed during several last decades (from 1950s to 2005) with the emphasis on different scales of variability (short-term, interannual, decadal). At all scales has been found a little consistency between the changes in turbulent surface fluxes diagnosed by reanalyses and blended data sets (OA-FLUX) on one hand and model simulations on the other. Furthermore, some models (e.g. ECHAM, IPSL) surprisingly demonstrate large regions with negative correlations between sensible and latent heat fluxes, which is not the case in observational data sets (reanalyses and OAFLUX). Interestingly, variability in air temperature and surface humidity (which could be potentially considered as the reason for autocorrelation between sensible and latent fluxes) demonstrates consistency with each other at most scales. Further we discuss potential reasons for the discovered phenomenon.

    2005-09-01

    The general principles of the mechanisms of heat transfer are well known, but knowledge of the transition between evaporative and non-evaporative heat loss by Holstein cows in field conditions must be improved, especially for low-latitude environments. With this aim 15 Holstein cows managed in open pasture were observed in a tropical region. The latent heat loss from the body surface of the animals was measured by means of a ventilated capsule, while convective heat transfer was estimated by the theory of convection from a horizontal cylinder and by the long-wave radiation exchange based on the Stefan-Boltzmann law. When the air temperature was between 10 and 36°C the sensible heat transfer varied from 160 to -30 W m-2, while the latent heat loss by cutaneous evaporation increased from 30 to 350 W m-2. Heat loss by cutaneous evaporation accounted for 20-30% of the total heat loss when air temperatures ranged from 10 to 20°C. At air temperatures >30°C cutaneous evaporation becomes the main avenue of heat loss, accounting for approximately 85% of the total heat loss, while the rest is lost by respiratory evaporation.

  10. The Influence of Aircraft Speed Variations on Sensible Heat-Flux Measurements by Different Airborne Systems

    2014-01-01

    Crawford et al. (Boundary-Layer Meteorol 66:237-245, 1993) showed that the time average is inappropriate for airborne eddy-covariance flux calculations. The aircraft's ground speed through a turbulent field is not constant. One reason can be a correlation with vertical air motion, so that some types of structures are sampled more densely than others. To avoid this, the time-sampled data are adjusted for the varying ground speed so that the modified estimates are equivalent to spatially-sampled data. A comparison of sensible heat-flux calculations using temporal and spatial averaging methods is presented and discussed. Data of the airborne measurement systems , Helipod and Dornier 128-6 are used for the analysis. These systems vary in size, weight and aerodynamic characteristics, since the is a small unmanned aerial vehicle (UAV), the Helipod a helicopter-borne turbulence probe and the Dornier 128-6 a manned research aircraft. The systematic bias anticipated in covariance computations due to speed variations was neither found when averaging over Dornier, Helipod nor UAV flight legs. However, the random differences between spatial and temporal averaging fluxes were found to be up to 30 % on the individual flight legs.

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

    PubMed

    Kennaway, James

    2010-07-01

    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.

    Muir, J.F.

    1986-01-01

    A major challenge facing the development of distributed receiver solar systems is the efficient transport of high temperature thermal energy from the collectors to the point of use. Conventional sensible (SEN) energy transport methods become less attractive as receiver temperatures increase due to increased heat losses and insulation costs. A promising alternative, that is particularly attractive for the high temperatures characteristic of paraboloidal dishes and the extensive piping associated with large collector fields, is the concept of thermochemical (TC) energy transport. Estimates of the performance and economics of 4 SEN and 2 TC transport systems for a dish collector field are compared at 4 delivery temperatures ranging from 400 to 815/sup 0/C. On the basis of levelized energy cost (LEC), there is no clear choice between SEN and TC energy transport at 400/sup 0/C. At higher output temperatures, TC transport is more cost-effective and is the only viable choice above about 700/sup 0/C. The carbon-dioxide reforming of methane TC system has the best performance and lowest costs at temperatures >400/sup 0/C and appears closest to meeting the DOE Solar Thermal Technology Program long-term IPH goal of 3 cent/kWh/sub t/ (9 $/MBtu) LEC. 23 refs., 9 figs., 5 tabs.

Estimates of the performance and economics of 4 SEN and 2TC transport systems for a dish collector field are compared at 4 delivery temperatures ranging from 400 to 815/sup 0/C. On the basis of levelized energy cost (LEC), there is no clear choice between SEN and TC energy transport at 400/sup 0/C. At higher output temperatures, TC transport is more cost-effective and is the only viable choice at temperatures above --700/sup 0/C. The TC system based on the carbon-dioxide reforming of methane has the best performance and lowest costs at temperatures >400/sup 0/C and appears closest to meeting the DOE Solar Thermal Technology (STT) Program long-term IPH goal of 3 cents/kWH/sub th/ (9$/MBtu/sub th/) LEC.

    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

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

  16. An Optimal Inverse Method Using Doppler Lidar Measurements to Estimate the Surface Sensible Heat Flux

    Inverse methods are widely used in various fields of atmospheric science. However, such methods are not commonly used within the boundary-layer community, where robust observations of surface fluxes are a particular concern. We present a new technique for deriving surface sensible heat fluxes from boundary-layer turbulence observations using an inverse method. Doppler lidar observations of vertical velocity variance are combined with two well-known mixed-layer scaling forward models for a convective boundary layer (CBL). The inverse method is validated using large-eddy simulations of a CBL with increasing wind speed. The majority of the estimated heat fluxes agree within error with the proscribed heat flux, across all wind speeds tested. The method is then applied to Doppler lidar data from the Chilbolton Observatory, UK. Heat fluxes are compared with those from a mast-mounted sonic anemometer. Errors in estimated heat fluxes are on average 18 %, an improvement on previous techniques. However, a significant negative bias is observed (on average ) that is more pronounced in the morning. Results are improved for the fully-developed CBL later in the day, which suggests that the bias is largely related to the choice of forward model, which is kept deliberately simple for this study. Overall, the inverse method provided reasonable flux estimates for the simple case of a CBL. Results shown here demonstrate that this method has promise in utilizing ground-based remote sensing to derive surface fluxes. Extension of the method is relatively straight-forward, and could include more complex forward models, or other measurements.

    Electrophysiological measurements of nerve impulse frequencies were used to explore the organization of taste sensibilities in single fibers of the hamster chorda tympani nerve. Moderately intense taste solutions that are either very similar or easily discriminated were applied to the anterior lingual surface. 40 response profiles or 13 stimulus activation patterns were considered variables and examined with multivariate statistical techniques. Three kinds of response profiles were seen in fibers that varied in their overall sensitivity to taste solutions. One profile (S) showed selectivity for sweeteners, a second (N) showed selectivity for sodium salts, and a third (H) showed sensitivity to salts, acids, and other compounds. Hierarchical cluster analysis indicated that profiles fell into discrete classes. Responses to many pairs of effective stimuli were covariant across profiles within a class, but some acidic stimuli had more idiosyncratic effects. Factor analysis of profiles identified two common factors, accounting for 77% of the variance. A unipolar factor was identified with the N profile, and a bipolar factor was identified with the S profile and its opposite, the H profile. Three stimulus activation patterns were elicited by taste solutions that varied in intensity of effect. Hierarchical cluster analysis indicated that the patterns fell into discrete classes. Factor analysis of patterns identified three common unipolar factors accounting for 82% of the variance. Eight stimuli (MgSO4, NH4Cl, KCl, citric acid, acetic acid, urea, quinine HCl, HCl) selectively activated fibers with H profiles, three stimuli (fructose, Na saccharin, sucrose) selectively activated fibers with S profiles, and two stimuli (NaNO3, NaCl) activated fibers with N profiles more strongly than fibers with H profiles. Stimuli that evoke different patterns taste distinct to hamsters. Stimuli that evoke the same pattern taste more similar. It was concluded that the hundreds of peripheral taste neurons that innervate the anterior tongue play one of three functional roles, providing information about one of three features that are shared by different chemical solutions.

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

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

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

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

    Surface fluxes of sensible and latent heat over a tall-grass prairie in central Kansas, as measured by 22 surface stations during FIFE 1987, are compared with values gained indirectly by linear extrapolation of aircraft-measured flux profiles to the surface. The results of 33 such comparisons covering the period 26 June to 13 October 1987 indicate that the sensible heat flux profiles were generally more linear with less scatter in the measurements at each level than were the latent heat flux profiles, the profile extrapolations of sensible heat flux in general underestimate the surface averages by about 30 percent, with slightly better agreement during periods of small flux, and the profile extrapolations of latent heat flux in general underestimate the surface averages by about 15 percent, with overestimates during periods of small fluxes (dry conditions) and overestimates during periods of large fluxes (moist conditions). Possible origins of the differences between the two sets of measurements are discussed, as directions for further research.

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

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

    Measurements of eddy-fluxes in an urban-suburban landscape may create technical difficulties as latent and sensible energy fluxes in the tower’s footprint are non-uniform. In an earlier study, we have found that the average vegetation cover surrounding the Cub Hill tower was 64 %; ranging from 46 to 77 % among 8 wind directions. We measured latent and sensible energy fluxes using a closed-path eddy-covariance system in the Cub Hill tower near Baltimore, Maryland. Half-hourly values of latent and sensible energy fluxes were stratified according to 24 15-degree bins of wind direction in each of the 16-day compositing periods for Normalized Difference Vegetation Index (NDVI) during 3 years of study (2004 to 2006). We used the daytime latent and sensible energy fluxes in the multivariate regression analyses to model fluxes of water vapor or evapotranspiration (ET) and sensible heat (H) as functions of micrometeorological variables (net radiation, temperature, relative humidity, wind speed, and soil moisture), NDVI, and land cover. Empirical models are developed at 16-day intervals for each of the 24 bins of wind direction to establish the relationships between energy fluxes (i.e., latent and sensible) and footprints (i.e., micrometeorology, NDVI, and land cover) around the Cub Hill tower.

    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

    Airborne measurements of flux densities of carbon dioxide CO2, sensible heat, and latent heat (H2O) obtained over the First ISLSCP Field Experiment (FIFE) site during three intensive field campaigns in 1987 and one in 1989 are examined to characterize the spatial and temporal variations of CO2 and energy transfer processes. These data were collected by the National Research Council Twin Otter using low-level flight patterns, all flown at constant pressure altitude during relatively clear days. The spatial variations are larger in 1989 than in 1987 and a higher correlation is observed between the fluxes and the surface features. The temporal patterns are easier to characterize with the relatively homogeneous situation of 1987. Functional relationships obtained between fluxes of CO2 and latent heat, CO2 fluxes and greenness index, latent heat fluxes and greenness index, and between sensible heat fluxes and surface air temperature differences are presented for one day in 1987 and one in 1989 as an example of the kind of information that can be obtained from grid flights at constant pressure altitude.

    A large aperture scintillometer (LAS) data sampled for the period from 1 February to 31 July 2014 at urban residential area in Seoul are modified using the variable Bowen ratio and a net radiation data to determine the space-averaged sensible heat flux (SHF). A LAS system is installed over the rooftop of two buildings with a distance between receiver and transmitter of 535 m, an effective height of 18.4 m, a wind speed sensor at 25.0 m high. The path-averaged building height, roughness length, and displacement length between the receiver and transmitter are 9.2 m, 0.4 m, and 7.1 m, respectively. The Bowen ratio computed at every 30 minute interval by the wind speed and air temperature at 10 and 18 m above the rooftop is found to be well correlated with meteorological variables such as net radiation and mixing ratio. Therefore, it is parameterized as a function of mixing ratio and net radiation. The resulting parameterization is applied to estimate the SHF by LAS. The Monin-Obukhov similarity universal function should be changed according to the atmospheric stability using the sign of net radiation sampled at the same time. It is found that the resulting sensible heat fluxes are available under all atmospheric stability and are much improved compared with those by eddy covariance method.

    In three patients sequential studies were performed of sensory and motor conduction after complete section and suture of the median nerve at the wrist and in one patient after partial section of the nerve. The sensory potential evoked by stimuli to digits III and I and recorded proximal to the suture line at the wrist appeared after a delay of three to four months, corresponding to a growth rate of 1.5-2.0 mm per day. From early in the course of regeneration the sensory potential was dispersed in 40 components. In the adult patient the cumulative amplitude increased for two years slowly and thereafter at a two times faster rate. Amplitude and tactile sensibility were normal after 40 months, but the sensory potential was still five times more dispersed than normal. The overall increase in the amplitude of the sensory potentials in children aged 10 and 12 years was three times faster than in adults. In the adults and in the children the maximum sensory conduction velocity was 10-25% of normal. It then increased at 3% per month during the first two years, and thereafter 10 times slower. Forty months after suture in the adults and 13-19 months after suture in the children the conduction velocity had reached 65-75% of normal. The pattern of discrete electrical activity during voluntary effort and the prolonged duration of motor unit potentials indicate persistent enlargement of the reinnervated motor units by peripheral sprouting. The sensory potential recovered five times faster after a compressive nerve lesion than after section and suture as seen in another patient with an affection of the ulnar nerve at the elbow. Normal tactile sensibility was attained 10 times faster than after section and suture. Maximum sensory and motor condution velocity recovered within one year from 60-70% to 80-90% of normal.

    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.

    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 screenhouses in two different climatic regions in Israel. Two field campaigns were carried out: In the first campaign we studied a banana plantation grown in a shading screenhouse in the coastal plane of northern Israel. In the second campaign a pepper plantation cultivated in an insect-proof screenhouse in the Jordan Valley region of eastern Israel 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 - 78 ?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 2°C. Best linear regressions between EC and SR sensible heat fluxes during validation were obtained for the thermocouples located adjacent to the screen, for both banana and pepper screenhouses. The coefficients of determination were generally higher for the banana than the pepper screenhouses. This was due to the effect of the insect-proof screen which induces a higher resistance to airflow than the light shading screen that covers the banana plantation. At both campaigns, results were better for unstable than for stable boundary layers. At stable conditions, and at unstable conditions 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.

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.

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

    Relations between an early interest in violent fantasy and children's social understanding, antisocial and emotional behavior, and interactions with friends were investigated in 40 "hard-to-manage" preschoolers and 40 control children matched for gender, age, and school and ethnic background. Children were filmed alone in a room with a friend, and tested on a battery of cognitive tests, including false-belief, executive function, and emotion understanding tasks. Teachers reported on their friendship quality. At age 6 years, the children's understanding of the emotional consequences of antisocial and prosocial actions was studied. The hard-to-manage group showed higher rates of violent fantasy; across both groups combined, violent fantasy was related to poor executive control and language ability, frequent antisocial behavior, displays of anger and refusal to help a friend, poor communication and coordination of play, more conflict with a friend, and less empathic moral sensibility 2 years later. The usefulness of a focus on the content of children's pretend play-in particular, violent fantasy-as a window on children's preoccupations is considered. PMID:11333080

The direct and medium-term consequences involve establishment of a health fund, but also drawing on tax money, e.g., to cofinance underage children. In addition, hospital outpatient departments in specialty fields are to be completely opened. All of these measures can lead to a marked reduction of specialized practices. All in all, one must bear in mind that establishing a "health fund" represents de facto the institution of state-run medicine. PMID:16874509

    During the twentieth century, the natural landscape of the Florida peninsula was transformed extensively by agriculture, urbanization, and the diversion of surface water features. The purpose of this paper is to present a numerical modeling study in which the possible impacts of this transformation on the warm season climate of the region were investigated. For three separate July-August periods (1973, 1989, and 1994), a pair of simulations was performed with the Regional Atmospheric Modeling System. Within each pair, the simulations differed only in the specification of land-cover class. The two different classes were specified using highly detailed datasets that were constructed to represent pre-1900 natural land cover and 1993 land-use patterns, thus capturing the landscape transformation within each pair of simulations. When the pre-1900 natural cover was replaced with the 1993 land-use dataset, the simulated spatial patterns of the surface sensible and latent heat flux were altered significantly, resulting in changes in the structure and strength of climatologically persistent, surface-forced mesoscale circulations-particularly the afternoon sea-breeze fronts. This mechanism was associated with marked changes in the spatial distribution of convective rainfall totals over the peninsula. When averaged over the model domain, this redistribution was reflected as an overall decrease in the 2-month precipitation total. In addition, the domain average of the diurnal cycle of 2-m temperature was amplified, with a noted increase in the daytime maximum. These results were consistent among all three simulated periods, and largely unchanged when subjected to a number of model sensitivity factors. Furthermore, the model results are in reasonable agreement with an analysis of observational data that indicates decreasing regional precipitation and increasing daytime maximum temperature during the twentieth century. These results could have important implications for water resource and land-use management issues in south Florida, including efforts to restore and preserve the natural hydroclimate of the Everglades ecosystem. This study also provides more evidence for the need to consider anthropogenic land-cover change when evaluating climate trends. ?? 2004 American Meteorological Society.

    A simple method is presented for using the daytime rise of the PBL height, combined with coincident satellite skin temperature measurements, to evaluate sensible heating and the effective surface roughness for heat transfer at synoptic locations. Multiple runs of a combination surface layer-mixed layer model are made in the central U.S., varying the values of surface moisture and roughness length around climatological means, and initializing the model with a set of atmospheric conditions from the synoptic report. The results, shown in figures and tables, are quite reasonable and spatially coherent, and depict well the sharp change in surface moisture and roughness which is known to take place across the central U.S.

    In this issue, Terasawa and colleagues used functional neuroimaging to test for common neural substrates supporting conscious appraisal of subjective bodily and emotional states and explored how the relationship might account for personality and experience of anxiety symptoms. Their study highlights a role for the same region of anterior insula cortex in appraisal of emotions and bodily physiology. The reactivity of this region also mediated the relationship between 'bodily sensibility' and social fear, translating a cognitive representation of subjective physical state into an individual personality trait that influences social interaction. The task used by Terasawa and colleagues taps into conscious aspects to the expression of this dynamic. These findings add to increasing evidence for the role of anterior insula as the interface between physiologically driven internal motivational states, emotional awareness and interpersonal behaviour.

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

    Using a dataset extended by the addition of data for 2004-2008, we re-examined the trend in the sensible heating (SH) flux at 73 meteorological stations over the Tibetan Plateau (TP) during 1980-2008 and investigated its impact on monsoon precipitation in the surrounding region. In contrast to ongoing climate warming, a weakening trend in SH is persistent over most of the plateau, despite a sharp increase in the ground-air temperature difference in 2004-2008. The weakening trend in SH over the TP is primarily a response to the spatial non-uniformity of large-scale warming over the East Asian continent, which is characterized by much greater warming amplitude at middle and high latitudes than over the tropics and subtropics. Furthermore, the suppressed air pump effect, which is driven by SH over the TP and acts as a strong forcing source, gives rise to reduced precipitation along the southern and eastern slopes of the plateau, and increased rainfall over northeastern India and the Bay of Bengal. No significantly stable correlation exists between the SH source over the TP and the overall trend or interdecadal variability in the East Asian or South Asian summer monsoon.

    We upscaled FLUXNET observations of carbon dioxide, water, and energy fluxes to the global scale using the machine learning technique, model tree ensembles (MTE). We trained MTE to predict site-level gross primary productivity (GPP), terrestrial ecosystem respiration (TER), net ecosystem exchange (NEE), latent energy (LE), and sensible heat (H) based on remote sensing indices, climate and meteorological data, and information on land use. We applied the trained MTEs to generate global flux fields at a 0.5° × 0.5° spatial resolution and a monthly temporal resolution from 1982 to 2008. Cross-validation analyses revealed good performance of MTE in predicting among-site flux variability with modeling efficiencies (MEf) between 0.64 and 0.84, except for NEE (MEf = 0.32). Performance was also good for predicting seasonal patterns (MEf between 0.84 and 0.89, except for NEE (0.64)). By comparison, predictions of monthly anomalies were not as strong (MEf between 0.29 and 0.52). Improved accounting of disturbance and lagged environmental effects, along with improved characterization of errors in the training data set, would contribute most to further reducing uncertainties. Our global estimates of LE (158 ± 7 J × 1018 yr-1), H (164 ± 15 J × 1018 yr-1), and GPP (119 ± 6 Pg C yr-1) were similar to independent estimates. Our global TER estimate (96 ± 6 Pg C yr-1) was likely underestimated by 5-10%. Hot spot regions of interannual variability in carbon fluxes occurred in semiarid to semihumid regions and were controlled by moisture supply. Overall, GPP was more important to interannual variability in NEE than TER. Our empirically derived fluxes may be used for calibration and evaluation of land surface process models and for exploratory and diagnostic assessments of the biosphere.

    The coupling behaviour of the Arctic atmospheric boundary layer with surface processes in different atmospheric situations is important for their parameterizations in numerical weather prediction and regional climate models. Ny-Ålesund is already known as a place where boundary layer measurements are challenged by local orographical effects. In this work we present data from two eddy covariance systems for determining the sensible heat flux, latent heat flux and the shear stress near the earth's surface, one close to the village (position: 78° 55.287' N, 011° 54.851' E), the other one located on Kongsvegen glacier (position: 78° 84.70' N, 012° 66.76' E) which was operated for a short period in April 2011 contemporary to the Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMiP) 2011. Two examples for small-scale variability are discussed: near surface external gravity waves associated with katabatic wind from the Broggerbreen glacier at the site Ny-Ålesund and an episode when the two eddy system at the two measurement sites captured very different conditions at the same time. In case of gravity wave motion the eddy covariance method results in fictitious positive fluxes due to the strong correlation between temperature and vertical wind, which had to be considered carefully. The comparison between the two sites showed, that generally the exchange processes near Ny-Ålesund and the Kongsvegen glacier are different and local. But there are cases of synchronization due to synoptical influences, and then the same processes are visible at the two measurement sites. Both examples show that the boundary layer in Ny-Ålesund is not only influenced from neighbouring glaciers, but also by other orographical characteristics, sometimes synoptical influences play the major role. It is clearly visible, that general statements about the Arctic boundary layer are mostly difficult with single measurements in space and time due to the high variability of the surface properties and meteorological conditions in Arctic regions.

    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%.

  17. Treatment of bipolar depression: making sensible decisions.

    PubMed

    Citrome, Leslie

    2014-12-01

    A major challenge in the treatment of major depressive episodes associated with bipolar disorder is differentiating this illness from major depressive episodes associated with major depressive disorder. Mistaking the former for the latter will lead to incorrect treatment and poor outcomes. None of the classic antidepressants, serotonin specific reuptake inhibitors, or serotonin-norepinephrine reuptake inhibitors have ever received regulatory approval as monotherapies for the treatment of bipolar depression. At present, there are only 3 approved medication treatments for bipolar depression: olanzapine/fluoxetine combination, quetiapine (immediate or extended release), and lurasidone (monotherapy or adjunctive to lithium or valproate). All 3 have similar efficacy profiles, but they differ in terms of tolerability. Number needed to treat (NNT) and number needed to harm (NNH) can be used to quantify these similarities and differences. The NNTs for response and remission for each of these interventions vs placebo range from 4 to 7, and 5 to 7, respectively, with overlap in terms of their 95% confidence intervals. NNH values less than 10 (vs placebo) were observed for the spontaneously reported adverse events of weight gain and diarrhea for olanzapine/fluoxetine combination (7 and 9, respectively) and somnolence and dry mouth for quetiapine (3 and 4, respectively). There were no NNH values less than 10 (vs placebo) observed with lurasidone treatment. NNH values vs placebo for weight gain of at least 7% from baseline were 6, 16, 58, and 36, for olanzapine/fluoxetine combination, quetiapine, lurasidone monotherapy, and lurasidone combined with lithium or valproate, respectively. Individualizing treatment decisions will require consideration of the different potential adverse events that are more likely to occur with each medication. The metric of the likelihood to be helped or harmed (LHH) is the ratio of NNH to NNT and can illustrate the tradeoffs inherent in selecting medications. A more favorable LHH was noted for treatment with lurasidone. However, OFC and quetiapine monotherapy may still have utility in high urgency situations, particularly in persons who have demonstrated good outcomes with these interventions in the past, and where a pressing clinical need for efficacy mitigates their potential tolerability shortcomings. In terms of maintenance therapy, adjunctive quetiapine is the only agent where the NNT vs lithium or valproate alone is less than 10 for both the prevention of mania and the prevention of depression.

  19. The psychopharmacology of violence: making sensible decisions.

    Violent behavior associated with mental disorders is a common reason for admission to a psychiatric inpatient unit. Once hospitalized, patients may continue to be intermittently agitated and have persistent aggressive behaviors, preventing their discharge back into the community. Managing agitation quickly with effective pharmacological agents can avoid further escalation to aggression and violence. In the acute setting, this usually involves the parenteral use of antipsychotics, with or without benzodiazepines. Within the past decade, short-acting intramuscular formulations of second-generation antipsychotics have become available and provide a means to induce calm with a substantially lower risk of acute dystonia or akathisia compared with haloperidol. New alternative formulations that avoid injections include inhalation and sublingual administration. Longer-term management of persistent aggressive behavior by reducing the frequency and intensity of future episodes of agitation is more complex. In contrast to agitation associated with schizophrenia or bipolar mania, no agents have yet been approved by regulatory agencies for the treatment of persistent aggressive behavior. The strongest evidence supports the use of clozapine as an antihostility agent, followed by olanzapine. Adjunctive strategies with anticonvulsants and beta-adrenergic agents may also be worthwhile to consider. PMID:24571828

  2. The invasion of non-native grasses into California grasslands has caused a shift in energy partitioning between latent and sensible heat flux, reduced albedo and higher surface temperatures

    In California, native grasses have been largely displaced across millions of acres of grassland habitat by the invasion of non-native grasses from Mediterranean Europe. Although seemingly subtle, this shift in grass species composition has altered the water and energy cycles in these ecosystems due to a shift in life cycle strategy. Native California grasses are perennial and long-lived. To survive California's long summer drought, they possess deep roots to harvest moisture along the full depth of the soil profile. Aboveground, most California perennial grasses are bunchy and dense, covering the ground and restricting soil evaporation. Their growing season extends over most of the year, thus maintaining an unbroken interaction along the soil-plant-atmosphere continuum, and enabling the plants to draw water from deep soil layers well into the dry summer. In contrast, the now-dominant non-native grasses are annuals. They grow from seed each year when Autumn rains begin, and die with the onset of summer drought. Aboveground, non-native annuals are sparse relative to native perennials, and possess a shallow root system with the large majority of root biomass above 20 cm depth. To determine the impact of this land cover shift on ecosystem water and energy cycles, we measured the components of the surface energy balance at a grassland site in northern coastal California where remnant perennial grasses are found growing alongside regions that have undergone non-native invasion. Specifically, in locations dominated by each grass type, we measured net radiation and ground and canopy heat flux through the surface renewal method. We also measured midday PAR albedo to determine the impact of grassland invasion on energy capture. In three years of measurements, corresponding to average, wet and dry years, we found that energy partitioning during the growing season is similar between grass types. However, once non-native annual grasses senesce in mid to late spring, the ratio of latent to sensible heat flux is higher where native perennial grasses are found, particularly in wet years. Annual sums of total evaporation are likewise higher in native-dominated regions, and soil moisture is lower relative to non-natives in the deep soil. We also found that PAR albedo is lower in native grasslands compared to non-natives during significant portions of the year, and corresponding to the hotter months. In all, our findings indicate that the non-native annual grasses which now dominate California grasslands, promote conditions that support higher surface temperatures relative to native perennial grasses.

    Four different rules have been suggested and validated for intensive care unit (ICU) admission for community-acquired pneumonia: modified American Thoracic Society (ATS) rule, Infectious Diseases Society of America (IDSA)/ATS rule, España rule, and SMART-COP. Their performance varies, with sensitivity of around 70% and specificity of around 80-90%. Only negative predictive values are consistently high. Critical methodological issues include the appropriate reference for derivation, the populations studied, the variables included, and the time course of pneumonia. Severe community-acquired pneumonia (SCAP) may evolve because of acute respiratory failure or/and severe sepsis/septic shock. Pneumonia-related complications and decompensated comorbidities may be additional or independent reasons for a severe course. All variables included in predictive rules relate to the two principal reasons for SCAP. However, taken as major criteria, they are of little value for clinical assessment. Instead, a limited set of minor criteria reflecting severity seems appropriate. However, predictive rules may not meet principal needs of severity assessment because of failure in sensitivity, ignorance of the potential contribution of complications or decompensated comorbidity to pneumonia severity, and poor sensitivity for the lower extreme in the spectrum of severe pneumonia, i.e., patients at risk of SCAP. We therefore advocate an approach that refers to the evaluation of the need for intensified treatment rather than ICU, based on a set of minor criteria and sensitive to the dynamic nature of pneumonia. Intensified treatment such as monitoring and treatment of acute respiratory failure or/and severe sepsis/septic shock is thought to improve management and possibly outcomes by setting the focus on both patients with severity criteria at admission and those at risk for SCAP.

    The probabilistic model building performed by estimation of distribution algorithms (EDAs) enables these methods to use advanced techniques of statistics and machine learning for automatic discovery of problem structures. However, in some situations, it may not be possible to completely and accurately identify the whole problem structure by probabilistic modeling due to certain inherent properties of the given problem. In this work, we illustrate one possible cause of such situations with problems consisting of structures with unequal fitness contributions. Based on the illustrative example, we introduce a notion that the estimated probabilistic models should be inspected to reveal the effective search directions and further propose a general approach which utilizes a reserved set of solutions to examine the built model for likely inaccurate fragments. Furthermore, the proposed approach is implemented on the extended compact genetic algorithm (ECGA) and experiments are performed on several sets of additively separable problems with different scaling setups. The results indicate that the proposed method can significantly assist ECGA to handle problems comprising structures of disparate fitness contributions and therefore may potentially help EDAs in general to overcome those situations in which the entire problem structure cannot be recognized properly due to the temporal delay of emergence of some promising partial solutions.

  13. Sense and sensibility: flagellum-mediated gene regulation.

    Anderson, Jennifer K; Smith, Todd G; Hoover, Timothy R

    2010-01-01

    The flagellum, a rotary engine required for motility in many bacteria, plays key roles in gene expression. It has been known for some time that flagellar substructures serve as checkpoints that coordinate flagellar gene expression with assembly. Less well understood, however, are other more global effects on gene expression. For instance, the flagellum acts as a 'wetness' sensor in Salmonella typhimurium, and as a mechanosensor in other bacteria. Additionally, it has been implicated in a variety of bacterial processes, including biofilm formation, pathogenesis and symbiosis. Although for many of these processes it might be simply that motility is required, in other cases it seems that the flagellum plays an underappreciated role in regulating gene expression.

    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.

    This paper proposes the impact assessment of the jobs order in the optimal time of operations in a Flexible Job Shop Scheduling Problem. In this work a real assembly cell was studied: the AIP-PRIMECA cell at the Université de Valenciennes et du Hainaut-Cambrésis, in France, which is considered as a Flexible Job Shop problem. The problem consists in finding the machines operations schedule, taking into account the precedence constraints. The main objective is to minimize the batch makespan, i.e. the finish time of the last operation completed in the schedule. Shortly, the present study consists in evaluating if the jobs order affects the optimal time of the operations schedule. The genetic algorithm was used to solve the optimization problem. As a conclusion, it's assessed that the jobs order influence the optimal time.

This is remarkably smaller than the best previously known bound. Our method is 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 $0.684$.

    Objective To clarify the modulatory effects of daily consumption of pomegranate extract (PE), olive oil (OO) and Nagilla sativa oil (NSO) on antioxidant activity, sperm quality and pituitary-testicular axis of adult male wistar rats. Methods Thirty-two adult male Wistar rats were divided into four equal groups, eight rats each. Using rat gastric tubes, 1.0 mL distilled water, 1.0 mL PE, 0.4 mL NSO and 0.4 mL OO were orally administered daily for 6 weeks in the first, second, third and fourth groups, respectively. Reproductive organs, body weight, sperm criteria, testosterone, FSH, LH, inhibin-B, lipid peroxidation, and antioxidant enzyme activities were investigated. At the end of the study protocol, analyses occurred at the same time. Data were analysed by ANOVA test and P<0.05 was considered to be a significant value. Results In all studied groups, malondialdehyde level was significantly decreased accompanied with an increases in glutathione peroxidase and glutathione. Rats treated with PE showed an increase in catalase activities accompanied with an increase in sperm concentration which was also observed in NSO group. In PE treated group, sperm motility was also increased accompanied with decreased abnormal sperm rate. NSO, OO and PE treated groups shows an insignificant effect on testosterone, inhibin-B, FSH and LH in comparison with control group. Conclusions These results show that administration of PE, NSO and OO could modify sperm characteristics and antioxidant activity of adult male wistar rats. PMID:23836459

    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.

    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

    Multiple chemical sensitivity (MCS) is a complex disorder initiated by chemical exposure, particularly through the airways. MCS patients report sensitivity or intolerance to low levels of a wide spectrum of chemicals. Symptoms could include asthma-like signs, rhinitis, fatigue, cognitive dysfunction, psycho-physiological alteration, and other specific tissue reactions resembling hypoxic and oxidative stress effects. To recognize physiological signs that would allow the diagnosis of MCS in a non-invasive way we investigated the potential application of a new sensor system. In healthy volunteers, we measured exhaled breath content in the control condition and under exposure to olfactory stressors that mimic hypoxic or pollutant stressors playing a potential role in the generation of the MCS disorder. The recording system used is based on metal oxide semiconductor (MOS) sensor having a sensing range of 450-2,000 ppm CO(2) equivalents, which is able to detect a broad range of compounds playing a potential role in the generation of the MCS disorder, while correlating directly with the CO(2) levels. The results indicate that the recording system employed was suitable for the analysis of exhaled breath content in humans. Interestingly, the system was able to detect and discriminate between the exhaled breath content taken from the control condition and those from conditions under stress that mimicked exposures to pollutant or hypoxia. The results suggest that chronic hypoxia could be involved in the MCS disorder. PMID:22836634

    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.

    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

    Mobile phones have become the leading communication system, with more than 4.5 billions users around the world. The sharp increase in the number of users, and its penetration to all populations, including children, has raised concern about possible adverse health effects, particularly cancer This article reviews the public health policies introduced in Israel and several other countries regarding mobile phone use in view of the lack of clarity concerning the safety of this new technology. The data show that most countries have adopted the precautionary principle as the leading guideline, recommending the use of simple and low-cost safety measures which could substantially reduce exposure to the brain and other body organs from mobile phones. These include the use of text messages, hands-free kits, and/or the loud-speaker mode of the phone. Accordingly, recommendations, guidelines, standards, and legislation aimed at the general population, drivers, state institutions and the industry have been formulated. For children, who are considered to be more susceptible to cancer development following exposure to carcinogens, there is widespread consensus for a stricter approach. In some countries, measures such as banning use of mobile phones in schools, prohibiting sales/advertisements targeted at young age groups, expanding warnings on phones/ packages, and encouraging educational campaigns have been adopted for this population. Regulations regarding phone use while driving have been instituted in most countries. In conclusion, many public health practitioners have moved from the theoretical level (adoption of the precautionary principle) to an active phase of introducing regulations, with specific emphasis to various populations.

    In therapeutic trials the use of manipulated cell cultures for clinical applications is often required. Mollicutes microorganism contamination of tissue cultures is a major problem because it can determine various and severe alterations in cellular function. Thus methods able to detect and trace cell cultures with Mollicutes contamination are needed in the monitoring of cells grown under good manufacturing practice conditions, and cell lines in continuous culture must be tested at regular intervals. We here describe a multiplex quantitative polymerase chain reaction assay able to detect contaminant Mollicutes species in a single-tube reaction through analysis of 16S-23S rRNA intergenic spacer regions and Tuf and P1 cytoadhesin genes. The method shows a sensitivity, specificity, and robustness comparable with the culture and the indicator cell culture as required by the European Pharmacopoeia guidelines and was validated following International Conference on Harmonization guidelines and Food and Drug Administration requirements.

    Energy balance components obtained over five grass-covered sloping surfaces near Manhattan, KS, using the Bowen ratio energy balance technique with the instruments mounted horizontally were compared with calculated values when the instruments were mounted parallel to the surfaces. Hourly values of the components changed when the instruments were parallel to the surfaces. The changes were larger at low solar angles (spring and fall) and on steeper slopes. An area average of daylight totals, assuming that all aspects were equally represented, changed only 0.1 percent on June 6 and 2.3 percent on October 11. The calculations, extended to steeper slopes, indicated small changes in the daylight totals for slopes of less than 10 deg.

    1998-06-01

    The role of alkali promoters in Fischer-Tropsch synthesis was investigated in terms of restricted adsorption/desorption mobility of hydrogen on the metal surface. A Fischer-Tropsch synthesis surface reaction model postulated by Kellner and Bell was modified for the removal of surface oxygen steps, and expressions were derived for methane formation rates and chain growth probabilities. The resulting expressions were analyzed in terms of decreased hydrogen adsorption equilibrium constant preexponentials upon alkali promotion. The model predictions were consistent with the experimental data, justifying the role of alkali promoters as modifiers of adsorption/desorption mobility of hydrogen while not interfering with the electronic structure of the metal catalyst.

    1940-01-01

    Infrared radiation (750–1500 mµ) produces no iris contraction in the typically nocturnal long-eared owl even when the energy content is millions of times greater than that of green light which easily elicits a pupil change. The energies in different parts of the visible spectrum required for a minimal iris response yield a spectral visibility curve for the owl which is the same as the human visibility curve at low light intensities. Functionally, the owl's vision thus corresponds to the predominantly rod structure of its retina, and the idea that nocturnal owls have a special type of vision sensitive to infrared radiation for seeing in the woods at night is erroneous.

    Anxiety sensitivity represents a stimulus-outcome expectancy that reflects individual differences in the propensity to experience fear in response to one's arousal-related bodily sensations. It refers to the fear of anxiety-related symptoms that are based on beliefs that such sensations have negative somatic, social or psychological consequences. Anxiety sensitivity occupies an important place in theory and research on panic and related interoceptive fear disorders. Findings from this body of research indicate that this construct may act as a specific vulnerability variable in the development of panic attacks and anxiety symptoms. However, anxiety sensitivity theory also has been applied to understanding mood disorders and chronic pain disorders. Thus, as a psychological construct, anxiety sensitivity holds specific relevance to understanding panic disorders and general relevance for expanding knowledge about negative emotional functioning in other pathologies. All the research on anxiety sensitivity has been completed with the 16-item Anxiety Sensitivity Index (ASI). The review of the literature using this instrument suggested that anxiety sensitivity has three lower-order factors that all load on a single higher-order factor. The lower-order factors represent Physical-Concerns, Mental Incapacitation Concerns, and Social Concerns, and the higher-order factor represents the global anxiety sensitivity construct (21). Taylor and Cox (22) suggested that this questionnaire was not designed on an a priori basis to measure the identified lower-order factors. The low number of items for the Social and Mental Incapacitation dimensions of the 16-item ASI often leads to relatively lower levels of reliability compared to the third dimension. To address this issue, Taylor and Cox (22) developed an expanded measure of the anxiety sensitivity construct. The 36-item Revised Anxiety Sensitivity Index (ASI-R) maintains the same format as the 16-item ASI, but expands the number of content domains assessed. The ASI-R was designed to assess 6 lower-order domains identified in previous factor analytic research using the 16-item ASI (21), including fear of cardiovascular symptoms, fear of respiratory symptoms, fear of gastrointestinal symptoms, fear of publicity observable reactions, fear of dissociative and neurological symptoms, and fear of cognitive dyscontrol. The principal components factor analysis using the ASI-R among psychiatric outpatients indicated that there were 4 lower-order factors tapping the constructs of (1) fear of respiratory symptoms, (2) fear of publicly observable anxiety reactions, (3) fear of cardiovascular symptoms, and (4) fear of cognitive dyscontrol (22). A recent study (27) provided an initial psychometric evaluation of the ASI-R in a large, diverse sample of people (n = 2,786) from 6 different countries: Canada, United States, Mexico, Spain, The Netherlands and France. The data suggested that the two-factor solution is most replicable than other solutions (2 to 6 factors). The underlying structure of the anxiety sensitivity construct was generally similar across countries, tapping fear about the negative consequences of anxiety-related physical and social-cognitive sensations. Lower-order factors were moderately to strongly correlated with one another and showed good internal consistency. This manuscript presents the French translation of the ASI-R and a preliminary validation study. This research was realized conjointly with the transcultural study previously mentioned (27). Seven hundred and one French university students (non-clinical participants) completed the questionnaire at the beginning of a class. Subjects were undergraduate students from 2 universities (psychology and classics). Table I provides age, sex and marital status. There were no differences between the two groups on sex. The two groups were not comparable on age and marital status. The psychology group was older than the other was. The psychology students were also more married.

    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.

    The exhaust gas from an internal combustion engine carries away about 30% of the heat of combustion. The energy available in the exit stream of many energy conversion devices goes as waste. The major technical constraint that prevents successful implementation of waste heat recovery is due to intermittent and time mismatched demand for and availability of energy. The present work

    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

    Direct spinning of the graphene oxide (GO) dispersions from a moveable spinneret along the programmed track, i.e., a "programmable writing" technique, was developed to make nonwoven, nonknitted, graphene-based networks with excellent mechanical properties. The resulting GO networks can be successfully converted into reduced GO (RGO) ones with better mechanical properties as well as excellent electrical conductivity via thermal/chemical reduction. In situ welded junctions formed during processing of the spun fibers have made the resulting networks with the integral structure, and outstanding mechanical properties and high electrical conductivities of the spun fibers and their web integrations have provided a great opportunity to remotely sense the external mechanical stimuli via electrical signal monitoring.

    Kálmán, János; Kálmán, János

    2010-06-01

    The cortico-limbic dysregulation theory of bipolar affective disorder (BAD) is supported by ample of recent research evidences. This concept is based on the dysharmonic regulation of prefrontal and anterior limbic structures manifested in a strong interaction of cognitive and affective symptoms. The major aim of the present review is to characterize the BAD specific cognitive profile and to describe the cognitive syndrome of BAD during the natural course of the disorder, based on recent findings in neurobiology, neuropathology, neuroradiology, cognitive psychology and neurogenetics. The authors recommend that BAD-associated cognitive symptoms should always be considered during the recognition, follow up and treatment phases of the disorder. The importance of the cognitive syndrome is also emphasized from the aspects of outcome and existing therapeutic regimens of the disorder. The cognitive syndrome-associated perspective of BAD could therefore provide new approaches regarding the long-term management issues of patients. Evidence from recent clinical trials is also summarized regarding the interactions of existing BAD treatment options with cognitive symptoms of the disorder, since all of the recommended antipsychotics and antiepileptics have a certain degree of cognitive toxicity. Based on the overview of the existing clinical trials, it was concluded that lamotrigine has the smallest cognitive toxicity among the mood stabilizers used for the treatment of BAD type-2. Therefore, as far as the cognitive toxicity profile is concerned, lamotrigine is recommended as the most promising therapeutic approach both for the treatment of bipolar depressive phases and relapse prevention. In addition, neuroprotective properties of the same molecule might also be beneficial regarding the proposed pathomechanism of BAD. PMID:20606245

    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.

    Gosselin, Gabriel

    Wetlands fill many important ecological functions and contribute to the biodiversity of fauna and flora. Although there is a growing recognition of the importance to protect these areas, it remains that their integrity is still threatened by the pressure of human activities. The inventory and the systematic monitoring of wetlands are a necessity and remote sensing is the only realistic way to achieve this goal. The primary objective of this thesis is to contribute and improve the wetland characterization using satellite polarimetric data acquired in L (ALOS-PALSAR) and C (RADARSAT-2) band. This thesis is based on two hypotheses (Ch. 1). The first hypothesis stipulate that classes of plant physiognomies, based on plant structure, are more appropriate than classes of plant species because they are best adapted to the information content of polarimetric radar data. The second hypothesis states that polarimetric decomposition algorithms allow an optimal extraction of polarimetric information compared to a multi-polarized approach based on the HH, HV and VV channels (Ch. 3). In particular, the contribution of the incoherent Touzi decomposition for the inventory and monitoring of wetlands is examined in detail. This decomposition allows the characterization of the scattering type, its phase, orientation, symmetry, degree of polarization and the backscattered power of a target with a series of parameters extracted from an analysis of the coherency matrix eigenvectors and eigenvalues. The lake Saint-Pierre region was chosen as the study site because of the great diversity of its wetlands that are covering more than 20 000 ha. One of the challenges posed by this thesis is that there is neither a standard system enumerating all the possible physiognomic classes nor an accurate description of their characteristics and dimensions. Special attention was given to the creation of these classes by combining several data sources and more than 50 plant species were grouped into nine physiognomic classes (Ch. 7, 8 and 9). Several analyzes are proposed to validate the hypotheses of this thesis (Ch. 9). Sensitivity analysis using scatter plots are performs to study the characteristics and dispersion of plant physiognomic classes in various features space consisting of polarimetric parameters or polarization channels (Ch. 10 and 12). Time series of made of RADARSAT-2 images are used to deepen the understanding of the seasonal evolution of plant physiognomies (Ch. 12). The transformed divergence algorithm is used to quantify the separability between physiognomic classes and to identify the parameters (s) that contribute the most to their separability (Ch. 11 and 13). Classifications are also proposed and the results compared to an existing map of the lake Saint-Pierre wetlands (Ch. 14). Finally, an analysis of the potential of polarimetric parameters in C and L-band is proposed for the monitoring of peatlands hydrology (Ch. 15 and 16). Sensitivity analyses show that the parameters of the 1st component, relative to the dominant (polarized) part of the signal, are sufficient for a general characterization of plant physiognomies. The parameters of the second and third components are, however, needed for better class separability (Ch. 11 and 13) and a better discrimination between wetlands and uplands (Ch. 14). This thesis shows that it is preferable to consider individually the parameters of the 1st, 2nd and 3rd components rather than their weighted sum by their respective eigenvalues (Ch. 10 and 12). This thesis also examines the complementarity between the structural parameters and those related to the backscattered power, often ignored and normalized by most polarimetric decomposition.

    2009-01-01

    Dental pulp testing is a useful and essential diagnostic aid in endodontics. Pulp sensibility tests include thermal and electric tests, which extrapolate pulp health from sensory response. Whilst pulp sensibility tests are the most commonly used in clinical practice, they are not without limitations and shortcomings. Pulp vitality tests attempt to examine the presence of pulp blood flow, as this is viewed as a better measure of true health than sensibility. Laser Doppler flowmetry and pulse oximetry are examples of vitality tests. Whilst the prospect is promising, there are still many practical issues that need to be addressed before vitality tests can replace sensibility tests as the standard clinical pulp diagnostic test. With all pulp tests, the results need to be carefully interpreted and closely scrutinised as false results can lead to misdiagnosis which can then lead to incorrect, inappropriate, or unnecessary treatment.

    PubMed Central

    2010-01-01

    In 1867, Federico Delpino, with his seminal work Pensieri sulla Biologia Vegetale (Thoughts on Plant Biology) established plant biology by defining it not in the broad general sense, namely as the science of living beings, but as a branch of natural science dedicated to the study of plant life in relation to the environment. Today, the figure and achievements of this outstanding plant scientist is almost unknown. In the following pages, I will concisely describe the main realizations of Federico Delpino and outline the significance of his work for modern plant science. PMID:21490417

    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.

  12. Evapotranspiration under advective conditions

    Arid and semi-arid regions are heterogeneous landscapes in which irrigated fields are surrounded by arid areas. The advection of sensible heat flux from dry surfaces is a significant source of energy that has to be taken into consideration when evaluating the evaporation from crops growing in these areas. The basic requirement of most of the common methods for estimating evapotranspiration [Bowen ratio, aerodynamic and Penman Monteith (PM) equation] is that the horizontal fluxes of sensible and latent heat are negligible when compared to the corresponding vertical fluxes. We carried out measurements above an irrigated tomato field in a desert area. Latent and sensible heat fluxes were measured using a four-level Bowen machine with aspirated psychrometers. Our results indicate that under advective conditions only measurements carried out in the lowest layer are satisfactory for the estimation of latent heat fluxes and that the use of the PM equation with an appropriately parameterized canopy resistance may be preferable.

    The observation made by early naturalists that some organisms could tolerate extreme environmental condisions and "enjoy the advantage of real resurrection after death" [ Spallanzani , M. Opuscules de Physique Animale et Vegetale 1776 (translated from Italian by Senebier , J. Opuscules de Physique Animale et Vegetale 1787 , 2 , 203 - 285 )] stimulated research that still continues to this day. Cryptobiosis, the ability of an organism to tolerate adverse environments, such as dehydration and low temperatures, still represents an unsolved and fascinating problem. It has been shown that many sugars play an important role as bioprotectant agents, and among the best performers is the disaccharide trehalose. The current hypothesis links the efficiency of its protective role to strong modifications of the tetrahedral arrangement of water molecules in the sugar hydration shell, with trehalose forming many hydrogen bonds with the solvent. Here, we show, by means of state-of-the-art neutron diffraction experiments combined with EPSR simulations, that trehalose solvation induces very minor modifications of the water structure. Moreover, the number of water molecules hydrogen-bonded to the sugar is surprisingly small. PMID:20297794

    The object of the invention is to provide a process for vaporizing liquid hydrocarbon fuels efficiently and without the formation of carbon residue on the apparatus used. The process includes simultaneously passing the liquid fuel and an inert hot gas downwardly through a plurality of vertically spaed apart regions of high surface area packing material. The liquid thinly coats the packing surface, and the sensible heat of the hot gas vaporizes this coating of liquid. Unvaporized liquid passing through one region of packing is uniformly redistributed over the top surface of the next region until all fuel has been vaporized using only the sensible heat of the hot gas stream.

    A numerical model is used to study the dissipation in the thermosphere of upward propagating acoustic waves. Whereas dissipating gravity waves can cool the upper atmosphere through the effects of sensible heat flux divergence, it is found that acoustic waves mainly heat the thermosphere by viscous dissipation. Though the amplitudes of acoustic waves in the atmosphere are poorly constrained, the

  2. Extension of the Averaging Time in Eddy-Covariance Measurements and Its Effect on the Energy Balance Closure

    NASA Astrophysics Data System (ADS)

    Charuchittipan, Doojdao; Babel, Wolfgang; Mauder, Matthias; Leps, Jens-Peter; Foken, Thomas

    2014-09-01

    The modified ogive analysis and the block ensemble average were employed to investigate the impact of the averaging time extension on the energy balance closure over six land-use types. The modified ogive analysis, which requires a steady-state condition, can extend the averaging time up to a few hours and suggests that an averaging time of 30 min is still overall sufficient for eddy-covariance measurements over low vegetation. The block ensemble average, which does not require a steady-state condition, can extend the averaging time to several days. However, it can improve the energy balance closure for some sites during specific periods, when secondary circulations exist in the vicinity of the sensor. These near-surface secondary circulations mainly transport sensible heat, and when near-ground warm air is transported upward, the sensible heat flux observed by the block ensemble average will increase at longer averaging times. These findings suggest an alternative energy balance correction for a ground-based eddy-covariance measurement, in which the attribution of the residual depends on the ratio of sensible heat flux to the buoyancy flux. The fraction of the residual attributed to the sensible heat flux by this energy balance correction is larger than in the energy balance correction that preserves the Bowen ratio.

  3. The Dynamics of Energy and CO2 Transport above a Subtropical Rice Paddy

    2014-05-01

    An eddy-covariance system was established to understand the dynamics of turbulent transport of sensible heat, water vapor, and CO2 above a subtropical rice paddy in north Taiwan (24°48'07.958"N, 121°47'58.665"E). The results showed that, during crop season, about 25% of net radiation was used for latent heat flux, 10% for sensible heat flux, and the rest (65%) was absorbed by the water and soil in the rice paddy. However, during fallow period, where there was no rice in the paddy, both water vapor and sensible heat fluxes occupied about 18% of the net radiation. Also, Penman-Monteith equation was found to reproduce the water vapor flux well with surface resistance close to 190 s m-1. We also found that, under small Bowen ratio (< 0.2) conditions, water vapor and CO2 were transported more efficiently than heat. However, when Bowen ration was large (> 0.5), sensible heat was transported about 10% more efficiently than water vapor and CO2. During crop season the maximum CO2 uptake was about 22 micro mol m-2 s-1. In fallow period, the maximum CO2 emission rate from the soil-water surface was around 5 micro mol m-2 s-1, which was about the same as the growing season.

    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.

    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.

    Latent loads represent a significant portion of the air conditioning loads in hot and humid climates. In this study, a novel application for a hybrid photovoltaic\\/thermal (PVT) collector, which produces electricity and hot water simultaneously, is investigated. The hybrid collector is used to drive a hybrid air conditioner that separates the sensible and latent loads. The hybrid air conditioner consists

    Thanks to the sensible and continuous improvements achieved, magnetic resonance imaging (MRI) can nowadays be considered the most accurate modality to image the liver. Moreover, the technique is the only one able to provide at the same time information about intracellular and vascular changes occurring in parenchymas. For these reasons, MRI plays a major role in the surveillance and follow-up

    The statistical properties of various measures of risk were investigated with a view to explaining the reasons for lack of use in finance of risk measures other than the variance, and to see if there is a sensible measure to use for cross-European comparisons. As examples, the semi-variance, the lower partial moment, the Gini, and the absolute deviation were considered.

    Nowadays, the need for intelligent software systems as personal meta search engines which are capable of supplying user by needed information from massive information resources is sensible. Moreover, the current tools have many deficiencies. In a meta search engine, proper queries based upon user's interests are sent to different search engines (or in general, information servers). Then, the returned results

    The meson (pion and kaon) form factor is calculated in the perturbative framework with alternative forms for the running coupling constant and the gluon propagator in the infrared kinematic region. These modified forms are employed to test the sensibility of the meson form factor to the nonperturbative contributions. It is a powerful discriminating quantity and the results obtained with a
