Retrieval of Coarse-Resolution Leaf Area Index over the Republic of Kazakhstan Using NOAA AVHRR Satellite Data and Ground Measurements
Creators: name: Propastin, Pavel

Publisher: name: FID GEO
Year: 2012

description: A new multi-decade national-wide coarse-resolution data set of leaf area index (LAI) over the Republic of Kazakhstan has been developed based on data from the Advanced Very High Resolution Radiometer (AVHRR) and in situ measurements of vegetation structure. The Kazakhstan-wide LAI product has been retrieved using an algorithm based on a physical radiative transfer model establishing a relationship between LAI and given patterns of surface reflectance, view-illumination conditions and optical properties of vegetation at the per-pixel scale. The results revealed high consistencies between the produced AVHRR LAI data set and ground truth information and the 30-m resolution Landsat ETM+ LAI estimated using the similar algorithm. Differences in LAI between the AVHRR-based product and the Landsat ETM+-based product are lower than 0.4 LAI units in terms of RMSE. The produced Kazakhstan-wide LAI was also compared with the global 8-km AVHRR LAI (LAI_PAL_BU_V3) and 1-km MODIS LAI (MOD15A2 LAI) products. Results show remarkable consistency of the spatial distribution and temporal dynamics between the new LAI product and both examined global LAI products. However, the results also revealed several discrepancies in LAI estimates when comparing the global and the Kazakhstan-wide products. The discrepancies in LAI estimates were outlined and discussed.

description: Using extended island formula we compute entanglement entropy of Hawking radiation for black hole solutions of certain gravitational models containing higher derivative terms. To be concrete we consider two different four dimensional models to compute entropy for both asymptotically flat and AdS black holes. One observes that the resultant entropy follows the Page curve, thanks to the contribution of the island, despite the fact that the corresponding gravitational models might be non-unitary.

description: In the light of global change, the necessity to monitor atmospheric depositions that have relevant effects on ecosystems is ever increasing particularly for tropical sites. For this study, atmospheric ionic depositions were measured on tropical Central Sulawesi at remote sites with both a conventional bulk water collector system (BWS collector) and with a passive ion exchange resin collector system (IER collector). The principle of IER collector to fix all ionic depositions, i.e. anions and cations, has certain advantages referring to (1) post-deposition transformation processes, (2) low ionic concentrations and (3) low rainfall and associated particulate inputs, e.g. dust or sand. The ionic concentrations to be measured for BWS collectors may easily fall below detection limits under low deposition conditions which are common for tropical sites of low land use intensity. Additionally, BWS collections are not as independent from the amount of rain fallen as are IER collections. For this study, the significant differences between both collectors found for nearly all measured elements were partly correlated to the rainfall pattern, i.e. for calcium, magnesium, potassium and sodium. However, the significant differences were, in most cases, not highly relevant. More relevant differences between the systems were found for aluminium and nitrate (434–484 %). Almost five times higher values for nitrate clarified the advantage of the IER system particularly for low deposition rate which is one particularity of atmospheric ionic deposition in tropical sites of extensive land use. The monthly resolution of the IER data offers new insights into the temporal distribution of annual ionic depositions. Here, it did not follow the tropical rain pattern of a drier season within generally wet conditions.
Processes of Contaminant Removal in Fe0-H2O Systems Revisited: The Importance of Co-Precipitation
Creators: name: Noubactep, Chicgoua
Publisher: name: FID GEO
Year: 2007

description: The mechanism of aqueous contaminant removal by elemental iron (Fe0) materials (e.g., in Fe0-H2O systems) has been largely discussed in the iron technology literature. Two major removal mechanisms are usually discussed: (i) contaminant adsorption onto Fe0 oxidation products, and (ii) contaminant reduction by Fe0, FeII or H/H2. However, a closer inspection of the chemistry of the Fe0-H2O system reveals that co-precipitation could be the primary removal mechanism. The plausibility of contaminant co-precipitation with iron corrosion products as independent contaminant removal mechanism is discussed here. It shows that the current concept does not take into account that the corrosion product generation is a dynamic process in the course of which contaminants are entrapped in the matrix of iron hydroxides. It is recalled that contaminant co-precipitation with iron hydroxides/oxides is an unspecific removal mechanism. Contaminant co-precipitation as primary removal mechanism is compatible with subsequent reduction and explains why redoxinsensitive species are quantitatively removed. Adsorption and co-precipitation precede reduction and abiotic reduction, when it takes place, occurs independently by a direct (electrons from Fe0) or an indirect (electrons from FeII/H2) mechanism.
title: Aspects of respiratory function during exercise in the thoroughbred horse in health and disease
Creators: name: Roberts, Colin Adrian
Publisher: name: The Open University
Year: 1995

description: The horse's enormous respiratory reserve enables it to increase the respiratory load on the lungs many fold during exercise, hence low-grade respiratory disease is difficult to detect at rest, although of vital importance during heavy exercise. Diagnostic exercise testing is, therefore, of great interest and this thesis describes its application to the investigation of respiratory disease in the Thoroughbred horse. Horses were exercised on a treadmill whilst respiratory flow rates were recorded using ultrasound flow transducers, respired gas concentrations measured by mass spectrometry and blood gas analysis performed. The exercise test involved a warm up followed by two minute canters/gallops at increasing workloads separated by ten minute walks. Validation studies confirmed the suitability of the methods for these studies. A steady state for respiratory variables was reached by ninety seconds of canter/gallop. The effects of training on exercising respiratory function were investigated by exercise testing horses following a sedentary period and after a fifteen week training programme. State of training did not complicate clinical interpretation of some variables, e.g tidal volume, respiratory frequency and minute ventilation, whilst peak flow rates were stable at the highest workloads. Arterial oxygen tension and blood pH during exercise were affected by training but other blood gas variables and end-tidal gas tensions were not. The effect of influenza on respiratory function was studied by challenging partially immune horses with H3N8 influenza, inducing infection similar to that seen in vaccinated racehorses. Twenty one days after infection most horses showed no changes in respiratory function but 2/9 horses altered breathing strategy during canter and another showed altered acid-base and blood lactate responses. Horses with low-grade respiratory disorders showed differences in respiratory function to the experimental animals but the wide normal range of pulmonary function tests limited their one-off diagnostic value. Serial testing may prove to be a more sensitive method.

description: We present a new mid-infrared (12.5micron) map of the BN/KL high-mass star-forming complex in Orion using the LWS instrument at Keck I. Despite poor weather we achieved nearly diffraction-limited images (FWHM = 0.38'') over a roughly 25'' X 25'' region centered on IRc2 down to a flux limit of ~250 mJy. Many of the known infrared (IR) sources in the region break up into smaller sub-components. We have also detected 6 new mid-IR sources. Nearly all of the sources are resolved in our mosaic. The near-IR source ''n'' is slightly elongated in the mid-IR along a NW--SE axis and perfectly bisects the double-peaked radio source ''L''. Source n has been identified as a candidate for powering the large IR luminosity of the BN/KL region (L = 10^5 L_sun). We postulate that the 12 micron emission arises in a circumstellar disk surrounding source n. The morphology of the mid-IR emission and the Orion ''hot core'' (as seen in NH_3 emission), along with the location of water and OH masers, is very suggestive of a bipolar cavity centered on source n and aligned with the rotation axis of the hypothetical circumstellar disk. IRc2, once thought to be the dominant energy source for the BN/KL region, clearly breaks into 4 sub-sources in our mosaic, as seen previously at 3.8 -- 5.0 micron. The anti-correlation of mid-IR emission and NH_3 emission from the nearby hot core indicates that the IRc2 sources are roughly coincident (or behind) the dense hot core. The nature of IRc2 is not clear: neither self-luminous sources (embedded protostars) nor external heating by source I can be definitively ruled out. We also report the discovery of a new arc-like feature SW of the BN object, and some curious morphology surrounding near-IR source ''t".

description: Despite two decades of intensive research on using metallic iron (Fe0) for environmental remediation and water treatment, basic concerns about their efficiency still prevail. This communication presents the basic idea of the view that challenges the prevailing paradigm on the operating mode of Fe0/H2O systems. The alternative paradigm is in tune with the mainstream science on aqueous iron corrosion. Its large scale adoption will enable a scientifically based system design and increase the acceptance of this already proven efficient technology.

description: Alkaline water electrolysis is considered a core technology for producing hydrogen on a large scale using renewable energy. Renewable energies characteristically exhibit a fluctuating and highly dynamic behavior. However, conventional electrolyzers are designed to operate under constant process conditions. To couple alkaline water electrolysis with renewable energy, efforts are needed to understand how dynamic operation impacts the durability of the electrolysis system.This work aims to evaluate the influence of intermittent operation on the durability of an alkaline electrolyzer. Within this study, the behavior of bare nickel electrodes responding to fluctuating potentials was evaluated. Several influencing factors were evaluated to investigate durability. Among these factors were various load types such as the holding of the potential and the cycling of the potential in triangular wave or square wave (Figures 1a-c). Furthermore, the response to a renewable energy input was investigated (Figure 1d). Ultimately, this will allow to elucidate the relation between performance losses during potential cycling and renewable load profiles.Overall, the research is critical in understanding how long-term performance will be affected as electrolysis shifts to an intermittent renewable power supply. The observations can provide metrics regarding future types and degrees of operational load to limit performance loss and can help assess long-term durability.

description: Objective: There is little research simultaneously examining both teen drivers’ characteristics and the driving environment. This study aimed to investigate how traffic engineering factors (road designs, traffic operations, and surface conditions) contribute to risks of teen driver’s fatality. Understanding the role of traffic engineering factors can further improve efforts to reduce teen diving-related fatal crashes. Methods: This study used the Fatality Analysis Reporting System and General Estimate System for years 2014 to 2015. We explored numerous engineering variables: horizontal/vertical alignment, intersections types, interchange areas, traffic ways types, posted speed limit, work zone areas, types of traffic control devices and road surface conditions. Traditional variables considered in this study included sex, age, presence of passengers in relation to age group, time of day, lighting condition, season, vehicle model year, vehicle type, seatbelt use, crash type and movement prior to a crash. We ran cross-tabulations and unadjusted analyses to report unadjusted odds ratios of teen driver’s fatality. A multiple logistic regression model was used to identify which variables related to road design and traffic operations remained significant after being adjusted by other variables. Results: For traditional factors, results corroborated prior findings. All the engineering factors, except work zone area, were significant in the unadjusted analyses; four variables – horizontal alignments, posted speed limit, traffic control device type, and traffic way type – remained statistically significant in the final model. The adjusted odds ratio (AOR) of curved high-speed segment was nearly seven times (6.94; 95% CI = 3.58, 13.46) that of a straight segment with a low posted speed limit (reference group). The AOR of no traffic control was four times (4.17; 95% CI = 2.95, 5.88) that of roads with traffic controls. The AOR of a two-way undivided road was almost three times (2.75, 95% CI = 1.43, 5.29) that of a two-way median barrier road (reference group). Conclusions: This study suggests teen driver education programs consider addressing road design characteristics. For example, incorporating focused lessons on traffic signs and traffic control types may better prepare young people for their driving experiences. Additionally, more supervised driving time is needed on various road types, especially those that present greater risks (e.g., roads with grades/curves, intersections with no traffic signal, undivided roads, and unpaved roads).

description: An external skeleton is an essential part of the body plan of many animals and is thought to be one of the key factors that enabled the great expansion in animal diversity and disparity during the Cambrian explosion. Molluscs are considered ideal to study the evolution of biomineralization because of their diversity of highly complex, robust and patterned shells. The molluscan shell forms externally at the interface of animal and environment, and involves controlled deposition of calcium carbonate within a framework of macromolecules that are secreted from the dorsal mantle epithelium. Despite its deep conservation within Mollusca, the mantle is capable of producing an incredible diversity of shell patterns, and macro- and micro-architectures. Here we review recent developments within the field of molluscan biomineralization, focusing on the genes expressed in the mantle that encode secreted proteins. The so-called mantle secretome appears to regulate shell deposition and patterning and in some cases becomes part of the shell matrix. Recent transcriptomic and proteomic studies have revealed marked differences in the mantle secretomes of even closely-related molluscs; these typically exceed expected differences based on characteristics of the external shell. All mantle secretomes surveyed to date include novel genes encoding lineage-restricted proteins and unique combinations of co-opted ancient genes. A surprisingly large proportion of both ancient and novel secreted proteins containing simple repetitive motifs or domains that are often modular in construction. These repetitive low complexity domains (RLCDs) appear to further promote the evolvability of the mantle secretome, resulting in domain shuffling, expansion and loss. RLCD families further evolve via slippage and other mechanisms associated with repetitive sequences. As analogous types of secreted proteins are expressed in biomineralizing tissues in other animals, insights into the evolution of the genes underlying molluscan shell formation may be applied more broadly to understanding the evolution of metazoan biomineralization.

description: Rural areas gained high tech jobs and plants over most of the period studied. This growth is, however, intimately tied to the historic economic base of rural communities, including primarily mature production manufacturing. Mature high tech industries, like their traditional counterparts, are relatively slow-growing and subject to future changes in a world-wide market system. Rural gains in high tech industry are also related to overall trends of industrial. decentralization. These larger trends have recently abated and thus the future of high tech growth in rural areas is in question. Rural communities making the most significant gains in high tech jobs are those adjacent to metropolitan areas. Those with the largest absolute numbers of high tech jobs are located near metropolitan areas in the Northeast and Midwest. In contrast, those experiencing the largest job gains over the study period are near cities in the South and West--another sign that rural high tech is tied to larger shifts of population and jobs among America's regions. States are active in recruitment and retention of high tech jobs and yet emphasis is rarely given to the unique problems of rural economies. Unless policy can be redirected toward enhancing existing industry competitiveness, it is doubtful rural communities will share in economic benefits of future high tech growth.
Neutral beam model for the anomalous gamma-ray emission component in GRB 941017

description: González et al. (2003) have reported the discovery of an anomalous radiation component from ~ 1 -- 200 MeV in GRB 941017. This component varies independently of and contains > 3 times the energy found in the prompt ~ 50 keV -- 1 MeV radiation component that is well described by the relativistic synchrotron-shock model. Acceleration of hadrons to very high energies can give rise to two additional emission components, one produced inside the GRB blast wave and one associated with an escaping beam of ultra-high energy (UHE; > 10^{14} eV) neutrons, gamma rays, and neutrinos. The first component extending to ~ 100 MeV is from a pair-photon cascade induced by photomeson processes with the internal synchrotron photons coincident with the prompt radiation. The outflowing UHE neutral beam can undergo further interactions with external photons from the backscattered photon field to produce a beam of hyper-relativistic electrons that lose most of their energy during a fraction of a gyroperiod in the assumed Gauss-strength magnetic fields of the circumburst medium. The synchrotron radiation of these electrons has a spectrum with vF_v index equal to +1 that can explain the anomalous component in GRB 941017. This interpretation of the spectrum of GRB 941017 requires a high baryon load of the accelerated particles in GRB blast waves. It implies that most of the radiation associated with the anomalous component is released at > 500 MeV, suitable for observations with GLAST, and with a comparable energy fluence in ~100 TeV neutrinos that could be detected with a km-scale neutrino telescope like IceCube.

description: Shape-morphing finds widespread utility, from the deployment of small stents and large solar sails to actuation and propulsion in soft robotics. Origami structures provide a template for shape-morphing, but rules for designing and folding the structures are challenging to integrate into broad and versatile design tools. Here, we develop a sequential two-stage optimization framework to approximate a general surface by a deployable origami structure. The optimization is performed over the space of all possible rigidly and flat-foldable quadrilateral mesh origami. So, the origami structures produced by our framework come with desirable engineering properties: they can be easily manufactured on a flat reference sheet, deployed to their target state by a controlled folding motion, then to a compact folded state in applications involving storage and portability. The attainable surfaces demonstrated include those with modest but diverse curvatures and unprecedented ones with sharp ridges. The framework provides not only a tool to design various deployable and retractable surfaces in engineering and architecture, but also a route to optimizing other properties and functionality.

An ancient process in a modern mollusc: early development of the shell in Lymnaea stagnalis
Creators: name: Hohagen, Jennifer
name: Jackson, Daniel J.
Publisher: name: FID GEO
Year: 2013

description: Background The morphological variety displayed by the molluscan shell underlies much of the evolutionary success of this phylum. However, the broad diversity of shell forms, sizes, ornamentations and functions contrasts with a deep conservation of early cell movements associated with the initiation of shell construction. This process begins during early embryogenesis with a thickening of an ectodermal, ‘dorsal’ (opposite the blastopore) population of cells, which then invaginates into the blastocoel to form the shell gland. The shell gland evaginates to form the shell field, which then expands and further differentiates to eventually become the adult shell-secreting organ commonly known as the mantle. Despite the deep conservation of the early shell forming developmental program across molluscan classes, little is known about the fine-scale cellular or molecular processes that underlie molluscan shell development. Results Using modern imaging techniques we provide here a description of the morphogenesis of a gastropod shell gland and shell field using the pulmonate gastropod Lymnaea stagnalis as a model. We find supporting evidence for a hypothesis of molluscan shell gland specification proposed over 60 years ago, and present histochemical assays that can be used to identify a variety of larval shell stages and distinct cell populations in whole mounts. Conclusions By providing a detailed spatial and temporal map of cell movements and differentiation events during early shell development in L. stagnalis we have established a platform for future work aimed at elucidation of the molecular mechanisms and regulatory networks that underlie the evo-devo of the molluscan shell.

Investigating an animal model of postpartum depression : the role of estradiol withdrawal in changes to adult hippocamp
Creators: name: Green, Amanda Dawn
Publisher: name: University of British Columbia
Year: 2011

description: 'Estradiol withdrawal' after pregnancy is hypothesized to precipitate depressive symptoms in vulnerable women. In this study, a hormonally-simulated 'pregnancy' was induced in ovariectomized female rats and the effect of a 'postpartum' drop in estradiol was examined on hippocampal cell proliferation (Experiment 1) and sucrose consumption, a model of anhedonia (Experiment 2). All non-sham groups were ovariectomized prior to treatment. Rats were randomly assigned to "pregnant", "pregnant + EB (estradiol benzoate)", "pregnant + IMI (imipramine; a tricyclic antidepressant)", "pregnant + DPN (diarylpropionitrile; an ERβ agonist)", "sham" or "ovariectomized (OVX)" controls and "sham/ovx + IMI" treatments. All "pregnant" groups received daily hormone injections (estradiol and progesterone) over 23 days to simulate pregnancy, while IMI groups also received daily injections of imipramine. After Day 23 of the "hormone simulated pregnancy", "pregnant" rats were withdrawn from the hormone regime (mimicking the postpartum drop in gonadal hormones), while other "pregnancy" groups received daily injections of compounds indicated (DPN, EB, IMI). In Experiment 1, on 'Postpartum' Day 3, all rats were injected with bromodeoxyuridine and perfused 24 hours later to assess cell proliferation and cell death, in the dentate gyrus. In Experiment 2 groups of rats were tested for consumption of, and preference for, sucrose weekly throughout 'pregnancy' and on 'Postpartum' Days 2-4. The "pregnant" group had significantly less cell proliferation in the dentate gyrus compared to all other groups except "pregnant +EB". Estradiol withdrawal after 'pregnancy' decreased cell proliferation and this decrease was reversed/prevented by imipramine or DPN treatment. Chronic imipramine increased cell proliferation in sham, but not ovariectomized, rats, suggesting that the imipramine-induced increase in hippocampal cell proliferation is related to reproductive status. In Experiment 2, all groups except "OVX" showed a significant decrease in body weight. Furthermore, there were trends for "pregnant" and "pregnant + EB" groups to have lower sucrose consumption and preference in the postpartum period compared to pregnancy. "OVX + IMI" had decreased sucrose consumption relative to OVX controls, suggesting a negative effect of imipramine on consumption. Together, these results suggest an important, though complex, role for gonadal hormones in the behavioural and cellular changes accompanying this depression model.

description: This paper presents an ‘optimally designed’ anti-collision trajectory plan suitable for moving target tracking in narrow spaces like corridors, aisles, etc. Narrow spaces constitute of highly constrained reachable states in the context of dynamic motion. Tracking is the default mode, while the safe trajectory is triggered on a priority-basis. The optimal switching point plays a key role in preventing a possible collision due to a ‘mis-timed’ change of manoeuvre, in case the obstacle shows unanticipated motion. Moreover, it also ensures that tracking is resumed at a point which minimises tracking error under the said deviation from the desired path. A smoothening filter has been proposed to make seamless transitions at the switching points.

description: We present a detailed study of chemical freeze-out in nucleus-nucleus collisions at beam energies of 11.6, 30, 40, 80 and 158A GeV. By analyzing hadronic multiplicities within the statistical hadronization approach, we have studied the strangeness production as a function of centre of mass energy and of the parameters of the source. We have tested and compared different versions of the statistical model, with special emphasis on possible explanations of the observed strangeness hadronic phase space under-saturation. We show that, in this energy range, the use of hadron yields at midrapidity instead of in full phase space artificially enhances strangeness production and could lead to incorrect conclusions as far as the occurrence of full chemical equilibrium is concerned. In addition to the basic model with an extra strange quark non-equilibrium parameter, we have tested three more schemes: a two-component model superimposing hadrons coming out of single nucleon-nucleon interactions to those emerging from large fireballs at equilibrium, a model with local strangeness neutrality and a model with strange and light quark non-equilibrium parameters. The behaviour of the source parameters as a function of colliding system and collision energy is studied. The description of strangeness production entails a non-monotonic energy dependence of strangeness saturation parameter gamma_S with a maximum around 30A GeV. We also present predictions of the production rates of still unmeasured hadrons including the newly discovered Theta^+(1540) pentaquark baryon.

description: Using the general formalism presented in Refs. [1,2], we study the finite-volume effects for the $\mathbf{2}+\mathcal{J}\to\mathbf{2}$ matrix element of an external current coupled to a two-particle state of identical scalars with perturbative interactions. Working in a finite cubic volume with periodicity $L$, we derive a $1/L$ expansion of the matrix element through $\mathcal O(1/L^5)$ and find that it is governed by two universal current-dependent parameters, the scalar charge and the threshold two-particle form factor. We confirm the result through a numerical study of the general formalism and additionally through an independent perturbative calculation. We further demonstrate a consistency with the Feynman-Hellmann theorem, which can be used to relate the $1/L$ expansions of the ground-state energy and matrix element. The latter gives a simple insight into why the leading volume corrections to the matrix element have the same scaling as those in the energy, $1/L^3$, in contradiction to earlier work, which found a $1/L^2$ contribution to the matrix element. We show here that such a term arises at intermediate stages in the perturbative calculation, but cancels in the final result.

description: This study assessed the functionality of metallic iron (Fe0) filtration systems using porous iron composite (PIC) as an alternative to granular Fe0/aggregate mixtures. The usage of PIC for water treatment has many challenges which are related to the well-drained nature of highly porous filters and the corresponding increase in hydraulic conductivity (shorter contact time). In this article, the extent of (i) iron exhaustion and (ii) porosity loss in four filtration systems are critically discussed. The considered filtration systems are: (i) Fe0 alone, (ii) PIC alone, (iii) Fe0/sand and (iv) Fe0/pumice. In all four systems, mono-sized granular spherical particles are assumed. Sand and Fe0 are compact (􀀁 = 0 %) whereas PIC and pumice are porous (e.g. 􀀁 = 40 %). Results demonstrated that under anoxic conditions (Fe3O4 as major corrosion products) Fe0 depletion is possible in all systems except Fe0 alone. Under oxic conditions (e.g. formation of Fe(OH)3), the PIC system exhibited the highest level of Fe0 depletion (58 %). The increasing order of sustainability was: Fe0 < Fe0/sand < Fe0/PM < PIC. These results suggested that manufacturing PIC with defined porosity and intrinsic reactivity is the key for more efficient usage of Fe0 for environmental remediation and water treatment.

bassin versant du Rhône

description: Constatant la progression des invasions biologiques sur les berges du bassin versant (BV) du Rhône inférieur, déjà bien dégradées, et la difficile reprise des ouvrages de génie végétal (GV) censés y répondre, la CNR veut s’inspirer de ripisylves et ouvrages de GV méridionaux afin d’anticiper la remontée du climat méditerranéen sur tout le BV, avec notamment l’intensification des sécheresses. À travers des entretiens et visites de ripisylves naturelles et d’ouvrages, nous avons analysé 90 retours d’expérience de GV du bassin méditerranéen, en France et en Espagne afin d’identifier d’éventuels facteurs de dégradation et décrire les pratiques, espèces, et techniques d’adaptation aux changements globaux. La moitié présentent des fascines de saule en pied de berge. Les facteurs d’échecs relevés sont similaires à ceux répertoriés ailleurs en France : âge de l’ouvrage, ombrage, concurrence…, avec une différence concernant l’ennoiement, le manque d’eau étant plus limitant. Pour pallier aux sécheresses, certains utilisent des rétenteurs d’humidité (boudins de coco, paillage avec hydrorétenteur), limitent la concurrence végétale ou réalisent leurs plantations à l’automne, avec des génotypes locaux adaptés. Au niveau espèces, les occurrences de leur utilisation sur les ouvrages de GV ont été couplés à des critères autécologiques et de résistance permettant de lister celles qui sont les plus adaptées à des conditions sèches, et de proposer des profils standards de berge de GV, synthèse incluant aussi les techniques suscitées. Des expérimentations in et ex-situ pourront à l’avenir confirmer leur pertinence.

Impacts of Rotation Axis and Frequency on Vestibular Perceptual Thresholds

description: In an effort to characterize the factors influencing the perception of self-motion rotational cues, vestibular self-motion perceptual thresholds were measured in 14 subjects for rotations in the roll and pitch planes, as well as in the planes aligned with the anatomic orientation of the vertical semicircular canals (i.e., left anterior, right posterior; LARP, and right anterior, left posterior; RALP). To determine the multisensory influence of concurrent otolith cues, within each plane of motion, thresholds were measured at four discrete frequencies for rotations about earth-horizontal (i.e., tilts; EH) and earth-vertical axes (i.e., head positioned in the plane of the rotation; EV). We found that the perception of rotations, stimulating primarily the vertical canals, was consistent with the behavior of a high-pass filter for all planes of motion, with velocity thresholds increasing at lower frequencies of rotation. In contrast, tilt (i.e, EH rotation) velocity thresholds, stimulating both the canals and otoliths (i.e., multisensory integration), decreased at lower frequencies and were significantly lower than earth-vertical rotation thresholds at each frequency below 2 Hz. These data suggest that multisensory integration of otolithic gravity cues with semicircular canal rotation cues enhances perceptual precision for tilt motions at frequencies below 2 Hz. We also showed that rotation thresholds, at least partially, were dependent on the orientation of the rotation plane relative to the anatomical alignment of the vertical canals. Collectively these data provide the first comprehensive report of how frequency and axis of rotation influence perception of rotational self-motion cues stimulating the vertical canals.
Photon and neutral pion production in Au+Au collisions at sqrt(s_{NN}) = 130 GeV

description: We report the first inclusive photon measurements about mid-rapidity (|y|<0.5) from Au+Au collisions at sqrt(s_{NN}) = 130 GeV at RHIC. Photon pair conversions were reconstructed from electron and positron tracks measured with the Time Projection Chamber (TPC) of the STAR experiment. With this method, an energy resolution of Delta(E)/E = 2% at 0.5 GeV has been achieved. Reconstructed photons have also been used to measure the transverse momentum (pt) spectra of pi0 mesons about mid-rapidity (|y|<1) via the pi0 -> photon photon decay channel. The fractional contribution of the pi0 -> photon photon decay to the inclusive photon spectrum decreases by 20% +/- 5% between pt = 1.65 GeV/c and pt = 2.4 GeV/c in the most central events, indicating that relative to pi0 -> photon photon decay the contribution of other photon sources is substantially increasing.

description: The adoption of green building certification schemes, such as Leadership in Energy and Environmental Design (LEED) for Schools, establishes common building factors among certified schools. Many building factors influence student performance outcomes including cognitive skills, standardized test scores and rates of absenteeism. This review synthesizes current research from 28 new studies and 101 other studies that were previously included in 15 reviews of associations between LEED-specified building factors and these performance outcomes in schools. In appraising the relative quantity and quality of studies, along with the frequency of LEED credits found in certified schools, this review finds that building features common to 100% of LEED-certified schools also have the strongest research supporting associations with academic outcomes, and largely come under the purview of indoor air quality (e.g., minimum ventilation rate, filtration or air cleaning) and acoustic performance. Comparatively, building factors related to the school site and daylighting have fewer associated studies, but findings suggest these are good targets for future research as they may be important for influencing student performance. Achieving a transition to a lower carbon future requires that schools be built with their energy impacts in mind; and this review provides value to those involved in the planning and design of these green schools that facilitate improved student performance outcomes.

description: The coprecipitation of U (VI) with iron corrosion products from aqueous solutions by zero valent iron was investigated. The evidence of coprecipitation was demonstrated by conducting experiments with well characterized scrap iron,pyrite and a mixture of both materials with experimental durations of up to four months. Results indicate that under anoxic conditions only less than one tenth of the immobilized U(VI) was associated with the surface of scrap iron, whereas theremaining amount is entrapped in aging corrosion products.
