Full Text Available Sex difference is an established risk factor for hematopoietic stem cell transplantation (HSCT-related complications like graft versus host disease (GVHD. CD8pos cytotoxic T cells specific for Y chromosome-encoded minor Histocompatibility antigens (HY play an important role therein. Prior to HSC donation, female donors may encounter HY antigens through fetomaternal or transmaternal cell flow, potentially leading to the induction of HY-specific cytotoxic or regulatory immune responses. Whether HY priming occurs independent of parity, and whether HY priming is dependent on the presence of male microchimerism, is as yet unknown.We investigated the presence of HY-specific regulatory T cells (Treg and male microchimerism in 45 healthy women with a fully documented pregnancy and family history. HY peptide-induced linked suppression, a commonly reported functional feature of CD4pos and CD8pos Treg, was measured by trans vivo Delayed Type Hypersensitivity testing. As source of HY antigens, male microchimerism was analyzed by real-time PCR and defined by the presence of male DNA in at least one purified leukocyte cell type.HLA class I or class II restricted HY-specific Treg were detected in 26/42 (62% women eligible for analysis. The prevalence of HY-specific Treg was significantly higher in women who had never given birth to sons than in women with male offspring (p = 0.004. Male microchimerism could be detected in 24 out of 45 (53% women but did not correlate with the presence of HY specific Treg.HY-specific Treg in women with male offspring have been described previously. Here we show for the first time that, in fact, HY specific Treg are more common in nulliparous women and in parous women with female offspring. Their presence is independent of the presence of male microchimerism. Whether HY-specific Treg presence in female stem cell grafts might decrease the GVHD incidence in male HSCT recipients needs to be investigated.

Hydrogen peroxide (H2O2) is not only a key mediator of oxidative stress but also one of the most important cellular second messengers. This small short-lived molecule is involved in the regulation of a wide range of different biological processes, including regulation of cellular signaling pathways. Studying the role of H2O2 in living systems would be challenging without modern approaches. A genetically encoded fluorescent biosensor, HyPer, is one of the most effective tools for this purpose. HyPer has been used by many investigators of redox signaling in various models of different scales: from cytoplasmic subcompartments and single cells to tissues of whole organisms. In many studies, the results obtained using HyPer have enabled a better understanding of the roles of H2O2 in these biological processes. However, much remains to be learned. In this review, we focus on the uses of HyPer. We provide a general description of HyPer and its improved versions. Separate chapters are devoted to the results obtained by various groups who have used this biosensor for their experiments in living cells and organisms. HyPer is an effective tool for H2O2 imaging in living systems as indicated by the increasing numbers of publications each year since its development. However, this biosensor requires further improvements. In particular, much brighter and more pH-stable versions of HyPer are necessary for imaging in mammalian tissues. Antioxid.

Development of HyPEP program for assessing the steady-state hydrogen production efficiency of the nuclear hydrogen production facilities was carried out. The main developmental aims of the HyPEP program are the extensive application of the GUI for enhanced user friendliness and the fast numerical solution scheme. These features are suitable for such calculations as the optimisation calculations. HyPEP was developed with the object-oriented programming techniques. The components of the facility was modelled as objects in a hierarchical structure where the inheritance property of the object oriented program were extensively applied. The Delphi program language which is based on the Object Pascal was used for the HyPEP development. The conservation equations for the thermal hydraulic flow network were setup and the numerical solution scheme was developed and implemented into HyPEP beta version. HyPEP beta version has been developed with working GUI and the numerical solution scheme implementation. Due to the premature end of this project the fully working version of HyPEP was not produced

The aims of the present study were to examine the surface topographies of intact HyFlex CM and HyFlex EDM nickel-titanium files and to compare alterations in the surface topographies of these files after root canal preparation of severely curved canals of molar teeth. Eight HyFlex CM (25/.08) and 8 HyFlex EDM (25/.08) files were included in the present study. In total, 64 severely curved canals of molar teeth, with curvature angles ranging between 50° and 70°, were prepared with HyFlex CM and EDM (n = 32 in each group). Quantitative and qualitative analyses of the files' surface deformation were performed by using three-dimensional optical profilometry before and after root canal preparation. The data were analyzed with the Student t test at the 5% significant level by using SPSS 21.0 software. In the HyFlex EDM group, the qualitative evaluation revealed the presence of cracks and microcavities after use of the file for root canal preparation, whereas only minor surface deformation was observed in the HyFlex CM group. The average roughness, root mean square roughness, and peak to valley height values of the HyFlex EDM group were significantly higher than those of the HyFlex CM group before and after root canal preparation (P EDM group was not statistically significant (P > .5). Within the limitations of the present study, the HyFlex CM files showed significantly higher surface alterations compared with the HyFlex EDM files after the preparation of severely curved root canals.

Effect of hydrostatic pressure on the deformation behavior of maraging and HY-80 steels and its implications for plasticity theory

International Nuclear Information System (INIS)

Spitzig, W.A.; Sober, R.J.; Richmond, O.

1976-01-01

Earlier results showed that the difference between the tensile and compressive strengths of tempered martensites is primarily a manifestation of the general pressure dependence of flow stress in these materials. However, the same results also showed that the volume expansion after deformation was much smaller than that predicted by the normality flow rule of plasticity theory for materials with such pressure dependence. Additional results now obtained on maraging and HY-80 steels support these conclusions. The results for all these materials exhibit a strong, but not perfect, correlation between pressure dependence, yield stress, and volume expansion. The volume expansion, however, which is believed to result primarily from the generation of new dislocations, is very small and does not appear to be essential to the pressure dependence. Most of the pressure dependence, the portion responsible for the discrepancy with the normality flow rule, may be an effect on dislocation motion. The results suggest that an appropriate plasticity model would be one in which the octahedral shear yield stress is linearly dependent on the mean pressure, but the volume change is negligible in violation of the normality flow rule. Such a model has been proposed previously for the plastic deformation of soils. However, unlike that model, the present theory includes strain hardening. 17 fig

This thesis is part of the project 'Providing hydrogen for transport in Norway: A social learning approach' and is financed through RENENERGI (Clean Energy) program. The Norway HyNor Project will provide a sensible means of providing hydrogen transportation along a test strip some 350 miles in length from the years 2005 to 2008. The project will also be quite challenging because of wide variations in climate and topology including very cold seasonal temperatures, not conducive to many fuel cell vehicles. As part of the signed Kyoto Treaty, Norway realized cutting emissions from power production was not a viable option, but perhaps they could take a bold step forward in implementing the infrastructure needed for a common and accessible means of hydrogen refueling. This alternative made sense because the emissions from hydrogen vehicles is zero compared to fossil fuel based vehicles which chug 1.5 billion tons of gas emissions into the environment. The Norway HyNor Project is working with both governmental agencies as well as the private sector to produce this hydrogen corridor. The plans include the commercial feasibility of large-scale hydrogen fuel based vehicles such as cars, taxis, trucks and buses. Private vehicles will also be used in this globally anticipated study and fueling stations are slated to be completed so that a real-world test case can provide the evidence needed for a shift in the world's fuel dependence.

The Multifaceted Roles of HY5 in Plant Growth and Development.

Science.gov (United States)

Gangappa, Sreeramaiah N; Botto, Javier F

2016-10-10

ELONGATED HYPOCOTYL5 (HY5), a member of the bZIP transcription factor family, inhibits hypocotyl growth and lateral root development, and promotes pigment accumulation in a light-dependent manner in Arabidopsis. Recent research on its role in different processes such as hormone, nutrient, abiotic stress (abscisic acid, salt, cold), and reactive oxygen species signaling pathways clearly places HY5 at the center of a transcriptional network hub. HY5 regulates the transcription of a large number of genes by directly binding to cis-regulatory elements. Recently, HY5 has also been shown to activate its own expression under both visible and UV-B light. Moreover, HY5 acts as a signal that moves from shoot to root to promote nitrate uptake and root growth. Here, we review recent advances on HY5 research in diverse aspects of plant development and highlight still open questions that need to be addressed in the near future for a complete understanding of its function in plant signaling and beyond.

Dental caries is caused by cariogenic biofilm, an oral biofilm including Streptococcus mutans . Recently, the prevention of dental caries using various probiotics has been attempted. Lactococcus lactis HY 449 is a probiotic bacterium. The aim of this study was to investigate the effect of L. lactis HY 449 on cariogenic biofilm and to analyze its inhibitory mechanisms. Cariogenic biofilm was formed in the presence or absence of L. lactis HY 449 and L. lactis ATCC 19435, and analyzed with a confocal laser microscope. The formation of cariogenic biofilm was reduced in cultures spiked with both L. lactis strains, and L. lactis HY 449 exhibited more inhibitory effects than L. lactis ATCC 19435. In order to analyze and to compare the inhibitory mechanisms, the antibacterial activity of the spent culture medium from both L. lactis strains against S. mutans was investigated, and the expression of glucosyltransferases ( gtfs ) of S. mutans was then analyzed by real-time RT-PCR. In addition, the sucrose fermentation ability of both L. lactis strains was examined. Both L. lactis strains showed antibacterial activity and inhibited the expression of gtfs , and the difference between both strains did not show. In the case of sucrose-fermenting ability, L. lactis HY 449 fermented sucrose but L. lactis ATCC 19435 did not. L. lactis HY 449 inhibited the uptake of sucrose and the gtfs expression of S. mutans , whereby the development of cariogenic biofilm may be inhibited. In conclusion, L. lactis HY 449 may be a useful probiotic for the prevention of dental caries.

Development of a Hydronic Rooftop Unit-HyPak-MA

Energy Technology Data Exchange (ETDEWEB)

Lee, Eric; Berman, Mark

2009-11-14

The majority of U.S. commercial floor space is cooled by rooftop HVAC units (RTUs). RTU popularity derives chiefly from their low initial cost and relative ease of service access without disturbing building occupants. Unfortunately, current RTUs are inherently inefficient due to a combination of characteristics that unnecessarily increase cooling loads and energy use. 36% percent of annual U.S. energy, and two-thirds of electricity, is consumed in and by buildings. Commercial buildings consume approximately 4.2 quads of energy each year at a cost of $230 billion per year, with HVAC equipment consuming 1.2 quads of electricity. More than half of all U.S. commercial floor space is cooled by packaged HVAC units, most of which are rooftop units (RTUs). Inefficient RTUs create an estimated 3.5% of U.S. CO{sub 2} emissions, thus contributing significantly to global warming5. Also, RTUs often fail to maintain adequate ventilation air and air filtration, reducing indoor air quality. This is the second HyPak project to be supported by DOE through NETL. The prior project, referred to as HyPak-1 in this report, had two rounds of prototype fabrication and testing as well as computer modeling and market research. The HyPak-1 prototypes demonstrated the high performance capabilities of the HyPak concept, but made it clear that further development was required to reduce heat exchanger cost and improve system reliability before HyPak commercialization can commence. The HyPak-1 prototypes were limited to about 25% ventilation air fraction, limiting performance and marketability. The current project is intended to develop a 'mixed-air' product that is capable of full 0-100% modulation in ventilation air fraction, hence it was referred to as HyPak-MA in the proposal. (For simplicity, the -MA has been dropped when referencing the current project.) The objective of the HyPak Project is to design, develop and test a hydronic RTU that provides a quantum improvement over

In vivo imaging of hydrogen peroxide with HyPer probes.

Hydrogen peroxide (H2O2) is a key signaling molecule involved in the regulation of both physiological and pathological cellular processes. Genetically encoded HyPer probes are currently among the most effective approaches for monitoring H2O2 dynamics in various biological systems because they can be easily targeted to specific cells and organelles. Since its development in 2006, HyPer has proved to be a robust and powerful tool in redox biology research. Recent Advances: HyPer probes were used in a variety of models to study the role of H2O2 in various redox process. HyPer has been increasingly used in the last few years for in vivo studies, which has already led to many important discoveries, for example, that H2O2 plays a key role in the regulation of signaling cascades involved in development and aging, inflammation, regeneration, photosynthetic signaling, and other biological processes. In this review, we focus on the main achievements in the field of redox biology that have been obtained from in vivo experiments using HyPer probes. Further in vivo studies of the role of H2O2 largely depend on the development of more suitable versions of HyPer for in vivo models: those having brighter fluorescence and a more stable signal in response to physiological changes in pH.

To compare the effect of autoclave cycles on the surface topography and roughness of HyFlex CM and HyFlex EDM instruments using atomic force microscopy (AFM) analysis. Eight new files of each brand were subdivided into four subgroups (n = 2/each subgroup). One group was allocated as the control group and not subjected to autoclave sterilization. The other three groups were subjected to different numbers (1, 5, and 10) of autoclave sterilization cycles. After the cycle instruments were subjected to AFM analysis. Roughness average (Ra) and the root mean square (RMS) values were chosen to investigate the surface features of endodontic files. The data was analyzed using one-way ANOVA and post hoc Tamhane tests at 5% significant level. The lowest Ra and RMS values were observed in the HyFlex EDM files that served as the control and in those subjected to a single cycle of autoclave sterilization (P cycles of autoclave sterilization (P cycles, whereas those of the HyFlex EDM group exhibited a significant change after five autoclave cycles (P cycles of autoclave sterilization. In contrast, the surface roughness values of the HyFlex CM files did not increase until 10 cycles of autoclave sterilization. Present study indicated that autoclave sterilization negatively affected the surface roughness of the tested NiTi files.

Full Text Available HY12 viruses are enteroviruses recently isolated from cattle characterized by severe respiratory and digestive disease with high morbidity and mortality in China. While the viruses exhibit unique biological and molecular characters distinct from known enterovirus E, the pathogenicity and viral pathogenesis remains largely unknown.Neonatal mice of Balb/C, ICR, and Kunming strain are infected with HY12 to determine the susceptible mouse strain. The minimal infection dose, the virus infection routes, the pathogenicity and tissue tropism for HY12 were determined by infecting susceptible mice with HY12 viruses, and confirmed by different approaches including virus isolation and recovery, virus detection, histopathology, and immunohistochemistry.A murine model for HY12 infection was successfully established and employed to investigate the pathogenicity of HY12 viruses. ICR mouse strain is the most susceptible strain for HY12 infection with a minimal infective dose as 2×106TCID50/mouse. HY12 viruses have the capability of infecting ICR suckling mice via all infection routes including intranasal administration, oral administration, intraperitoneal injection, subcutaneous injection, and intramuscular injection, which are confirmed by the isolation and recovery of viruses from HY12-infected mice; detection of viruses by RT-PCR; observations of pathological lesions and inflammatory cell infiltrations in the intestine, lung, liver, and brain; uncovering of HY12 virus antigens in majority of tissues, especially in intestine, lung, and infected brain of mice by immunohistochemistry assay.A neonatal murine model for HY12 infection is successfully established for determining the susceptible mouse strain, the minimal infective dose, the infection route, the viral pathogenicity and the tropism of HY12, thus providing an invaluable model system for elucidating the pathogenesis of HY12 viruses and the elicited immunity.

Response properties of the genetically encoded optical H2O2 sensor HyPer.

Weller, Jonathan; Kizina, Kathrin M; Can, Karolina; Bao, Guobin; Müller, Michael

2014-11-01

Reactive oxygen species mediate cellular signaling and neuropathologies. Hence, there is tremendous interest in monitoring (sub)cellular redox conditions. We evaluated the genetically engineered redox sensor HyPer in mouse hippocampal cell cultures. Two days after lipofection, neurons and glia showed sufficient expression levels, and H2O2 reversibly and dose-dependently increased the fluorescence ratio of cytosolic HyPer. Yet, repeated H2O2 treatment caused progressively declining responses, and with millimolar doses an apparent recovery started while H2O2 was still present. Although HyPer should be H2O2 specific, it seemingly responded also to other oxidants and altered cell-endogenous superoxide production. Control experiments with the SypHer pH sensor confirmed that the HyPer ratio responds to pH changes, decreasing with acidosis and increasing during alkalosis. Anoxia/reoxygenation evoked biphasic HyPer responses reporting apparent reduction/oxidation; replacing Cl(-) exerted only negligible effects. Mitochondria-targeted HyPer readily responded to H2O2-albeit less intensely than cytosolic HyPer. With ratiometric two-photon excitation, H2O2 increased the cytosolic HyPer ratio. Time-correlated fluorescence-lifetime imaging microscopy (FLIM) revealed a monoexponential decay of HyPer fluorescence, and H2O2 decreased fluorescence lifetimes. Dithiothreitol failed to further reduce HyPer or to induce reasonable FLIM and two-photon responses. By enabling dynamic recordings, HyPer is superior to synthetic redox-sensitive dyes. Its feasibility for two-photon excitation also enables studies in more complex preparations. Based on FLIM, quantitative analyses might be possible independent of switching excitation wavelengths. Yet, because of its pronounced pH sensitivity, adaptation to repeated oxidation, and insensitivity to reducing stimuli, HyPer responses have to be interpreted carefully. For reliable data, side-by-side pH monitoring with SypHer is essential. Copyright �

Indications of anti-HY immunity in recurrent placental abruption

DEFF Research Database (Denmark)

Nielsen, Henriette Svarre; Mogensen, Marie; Steffensen, Rudi

2007-01-01

PROBLEM: Placental abruption is a potential life-threatening condition for both the fetus and the mother, being significantly more common in pregnancies with male fetuses. The pathogenesis of placental abruption remains unknown. However, some recent reports point toward a maternal immune response...... the fetus died. Seven patients (88%) had first-born boys, and 15 abruptions (68%) involved male fetuses. All patients with a first-born boy, except one, had HLA-class II alleles known to restrict CD4+ T-cell responses against male-specific minor histocompatibility (HY)-antigens (HLA-DRB1*15, HLA-DRB3...... abruption is exclusively almost preceded by the birth of a boy and the majority of patients have HLA-class II known to restrict CD4 T-cell reactions against HY-antigens. This indicates that maternal immunological responses against HY-antigens play a role in recurrent placental abruption. Udgivelsesdato...

HyDe: a Python Package for Genome-Scale Hybridization Detection.

Science.gov (United States)

Blischak, Paul D; Chifman, Julia; Wolfe, Andrea D; Kubatko, Laura S

2018-03-19

The analysis of hybridization and gene flow among closely related taxa is a common goal for researchers studying speciation and phylogeography. Many methods for hybridization detection use simple site pattern frequencies from observed genomic data and compare them to null models that predict an absence of gene flow. The theory underlying the detection of hybridization using these site pattern probabilities exploits the relationship between the coalescent process for gene trees within population trees and the process of mutation along the branches of the gene trees. For certain models, site patterns are predicted to occur in equal frequency (i.e., their difference is 0), producing a set of functions called phylogenetic invariants. In this paper we introduce HyDe, a software package for detecting hybridization using phylogenetic invariants arising under the coalescent model with hybridization. HyDe is written in Python, and can be used interactively or through the command line using pre-packaged scripts. We demonstrate the use of HyDe on simulated data, as well as on two empirical data sets from the literature. We focus in particular on identifying individual hybrids within population samples and on distinguishing between hybrid speciation and gene flow. HyDe is freely available as an open source Python package under the GNU GPL v3 on both GitHub (https://github.com/pblischak/HyDe) and the Python Package Index (PyPI: https://pypi.python.org/pypi/phyde).

HyPro: A Multi-DoF Hybrid-Powered Transradial Robotic Prosthesis

Directory of Open Access Journals (Sweden)

C. L. Semasinghe

2018-01-01

Full Text Available This paper proposes a multi-DoF hybrid-powered transradial robotic prosthesis, named HyPro. The HyPro consists of two prosthetic units: hand and wrist that can achieve five grasping patterns such as power grasp, tip grasp, lateral grasp, hook grasp, and index point. It is an underactuated device with 15 degrees of freedom. A hybrid powering concept is proposed and implemented on hand unit of HyPro where the key focus is on restoration of grasp functions of biological hand. A novel underactuated mechanism is introduced to achieve the required hand preshaping for a given grasping pattern using electric power in the pregrasp stage and body power is used in grasp stage to execute the final grasping action with the selected fingers. Unlike existing hybrid prostheses where each of the joints is separately controlled by either electric or body power, the proposed prosthesis is capable of delivering grasping power in combination. The wrist unit of HyPro is designed and developed to achieve flexion-extension and supination-pronation using electric power. Experiments were carried out to evaluate the functionality and performance of the proposed hybrid-powered robotic prosthesis. The results verified the potential of HyPro to perform intended grasping patterns effectively and efficiently.

Economic Analysis for Nuclear Hydrogen Production System Based on HyS Process

International Nuclear Information System (INIS)

Yang, Kyeong Jin; Lee, Ki Young; Lee, Tae Hoon; Chang, Jong Hwa

2009-01-01

The current promising base for massive hydrogen production on high temperature environment derives primarily from three sources: the commercial production of chemicals for the sulfur-iodine (SI) process, the development of solid-oxide fuel cells (SOFC), and the hybrid method of chemicals and fuel cells. The three kinds of process requires high temperature heat energy over 850∼950 .deg. C for the efficient and economic hydrogen production. One of the clean, economic, and moreover promising heat sources supplied to the process is nuclear plants. The nuclear plants producing high temperature heat energy over 950 .deg. C are well known as Very High Temperature Reactors (VHTR) which could have two types of prismatic and pebble-bed cores along reactor core shape. In this paper, we report on the Hybrid Sulfur Process (HyS), and the estimated costs for the system which composes of VHTR of prismatic core type and HyS plant. Nuclear hydrogen production system based on HyS process has been configured to optimally use the thermal energy from VHTR and electric energy to produce hydrogen and oxygen from clean water. High temperature thermal energy is transferred to the HyS process by way of intermediate heat exchanger (IHX) with associated piping. In this paper, the hydrogen production costs for a system composed of a VHTR with six 600MWth module, a power conversion unit (PCU) and a HyS plant are presented, where the thermal energy produced in two module was converted to electric energy in PCU and then transferred to the electrolysis cells for hydrogen production and circulating units on HyS plant, and the remaining thermal energy was supplied to chemical process on HyS plants. As a preliminary study of cost estimates for nuclear hydrogen systems, the hydrogen production costs of the nuclear energy sources benchmarking GT-MHR are estimated in the necessary input data on a Korean specific basis. G4- ECONS was appropriately modified to calculate the cost for hydrogen production

To synthesize a (2-Hydroxypropyl)-γ-cyclodextrin-polyethylenimine/adamantane-conjugated doxorubicin (γ-hy-PC/Ada-Dox) based supramolecular nanoparticle with host-guest interaction and to identify its physicochemical characterizations and antitumor effect. A novel non-viral gene delivery vector γ-hy-PC/Ada-Dox was synthesized based on host-guest interaction. 1H-NMR, NOESY, UV-Vis, XRD and TGA were used to confirm the structure of the vector. The DNA condensing ability of complexes was investigated by particle size, zeta potential and gel retardation assay. Cytotoxicity of complexes was determined by MTT assay in BEL-7402 and SMMC-7721 cells. Cell wound healing assay was performed in HEK293 and BEL-7404 cells. The transfection efficiency was investigated in HEK293 cells. H/E staining and cell uptake assay was performed in BEL-7402 cells. The structure of γ-hy-PC/Ada-Dox was characterized by 1H-NMR, NOESY, UV-Vis, XRD, TGA. The drug loading was 0.5% and 5.5%. Gel retardation assay showed that γ-hy-PC was able to completely condense DNA at N/P ratio of 2; 0.5% and 5.5% γ-hy-PC/Ada-Dox was able to completely condense DNA at N/P ratio of 3 and 4,respectively. The cytotoxicity of polymers was lower than that of PEI25KDa. The transfection efficiency of γ-hy-PC was higher than that of γ-hy-PC/Ada-Dox at N/P ratio of 30 in HEK293 cells; and the transfection efficiency was decreasing when Ada-Dox loading was increasing. Cell uptake assay showed that γ-hy-PC/Ada-Dox was able to carry drug and FAM-siRNA into cells. The novel vector γ-hy-PC/Ada-Dox has been developed successfully, which has certain transfection efficiency and antitumor activity.

Hydrologic Drought Decision Support System (HyDroDSS)

Science.gov (United States)

Granato, Gregory E.

2014-01-01

The hydrologic drought decision support system (HyDroDSS) was developed by the U.S. Geological Survey (USGS) in cooperation with the Rhode Island Water Resources Board (RIWRB) for use in the analysis of hydrologic variables that may indicate the risk for streamflows to be below user-defined flow targets at a designated site of interest, which is defined herein as data-collection site on a stream that may be adversely affected by pumping. Hydrologic drought is defined for this study as a period of lower than normal streamflows caused by precipitation deficits and (or) water withdrawals. The HyDroDSS is designed to provide water managers with risk-based information for balancing water-supply needs and aquatic-habitat protection goals to mitigate potential effects of hydrologic drought. This report describes the theory and methods for retrospective streamflow-depletion analysis, rank correlation analysis, and drought-projection analysis. All three methods are designed to inform decisions made by drought steering committees and decisionmakers on the basis of quantitative risk assessment. All three methods use estimates of unaltered streamflow, which is the measured or modeled flow without major withdrawals or discharges, to approximate a natural low-flow regime. Retrospective streamflow-depletion analysis can be used by water-resource managers to evaluate relations between withdrawal plans and the potential effects of withdrawal plans on streams at one or more sites of interest in an area. Retrospective streamflow-depletion analysis indicates the historical risk of being below user-defined flow targets if different pumping plans were implemented for the period of record. Retrospective streamflow-depletion analysis also indicates the risk for creating hydrologic drought conditions caused by use of a pumping plan. Retrospective streamflow-depletion analysis is done by calculating the net streamflow depletions from withdrawals and discharges and applying these depletions

Effect of Si/Al2 Ratio on 2-butanol Dehydration over HY Zeolite Catalysts

International Nuclear Information System (INIS)

Jung, Euna; Choi, Hyeonhee; Jeon, Jong-Ki

2015-01-01

Synthesis of butenes through dehydration of 2-butanol was investigated over HY zeolite catalysts. 2-Butanol dehydration reaction was carried out in a fixed bed catalytic reactor. 2-Butanol conversion was increased with increase of Si/Al 2 ratio of HY zeolite catalysts, which can be ascribed to increase of acid strength with increase of Si/Al 2 ratio. Selectivities to 1-butene, trans-2-butene, and cis-2-butene were not greatly influenced by the change of the Si/Al 2 ratio of HY zeolite. As a result, it was advantageous to use a HY zeolite catalyst with 60 Si/Al 2 ratio for maximizing the yield of 1-butene in the dehydration of 2-butanol. The optimal reaction temperature for maximizing the yield of 1-butene was 250 .deg. C over HY (60) catalyst

2017-03-01

The HyRAM software toolkit provides a basis for conducting quantitative risk assessment and consequence modeling for hydrogen infrastructure and transportation systems. HyRAM is designed to facilitate the use of state-of-the-art science and engineering models to conduct robust, repeatable assessments of hydrogen safety, hazards, and risk. HyRAM is envisioned as a unifying platform combining validated, analytical models of hydrogen behavior, a stan- dardized, transparent QRA approach, and engineering models and generic data for hydrogen installations. HyRAM is being developed at Sandia National Laboratories for the U. S. De- partment of Energy to increase access to technical data about hydrogen safety and to enable the use of that data to support development and revision of national and international codes and standards. This document provides a description of the methodology and models contained in the HyRAM version 1.1. HyRAM 1.1 includes generic probabilities for hydrogen equipment fail- ures, probabilistic models for the impact of heat flux on humans and structures, and computa- tionally and experimentally validated analytical and first order models of hydrogen release and flame physics. HyRAM 1.1 integrates deterministic and probabilistic models for quantifying accident scenarios, predicting physical effects, and characterizing hydrogen hazards (thermal effects from jet fires, overpressure effects from deflagrations), and assessing impact on people and structures. HyRAM is a prototype software in active development and thus the models and data may change. This report will be updated at appropriate developmental intervals.

Full Text Available A sea ice detection algorithm based on Fisher’s linear discriminant analysis is developed to segment sea ice and open water for the Ku-band scatterometer onboard the China’s Hai Yang 2A Satellite (HY-2A/SCAT. Residual classification errors are reduced through image erosion/dilation techniques and sea ice growth/retreat constraint methods. The arctic sea-ice-type classification is estimated via a time-dependent threshold derived from the annual backscatter trends based on previous HY-2A/SCAT derived sea ice extent. The extent and edge of the sea ice obtained in this study is compared with the Special Sensor Microwave Imager/Sounder (SSMIS sea ice concentration data and the Sentinel-1 SAR imagery for verification, respectively. Meanwhile, the classified sea ice type is compared with a multi-sensor sea ice type product based on data from the Advanced Scatterometer (ASCAT and SSMIS. Results show that HY-2A/SCAT is powerful in providing sea ice extent and type information, while differences in the sensitivities of active/passive products are found. In addition, HY-2A/SCAT derived sea ice products are also proved to be valuable complements for existing polar sea ice data products.

2015-02-15

Synthesis of butenes through dehydration of 2-butanol was investigated over HY zeolite catalysts. 2-Butanol dehydration reaction was carried out in a fixed bed catalytic reactor. 2-Butanol conversion was increased with increase of Si/Al{sub 2} ratio of HY zeolite catalysts, which can be ascribed to increase of acid strength with increase of Si/Al{sub 2} ratio. Selectivities to 1-butene, trans-2-butene, and cis-2-butene were not greatly influenced by the change of the Si/Al{sub 2} ratio of HY zeolite. As a result, it was advantageous to use a HY zeolite catalyst with 60 Si/Al{sub 2} ratio for maximizing the yield of 1-butene in the dehydration of 2-butanol. The optimal reaction temperature for maximizing the yield of 1-butene was 250 .deg. C over HY (60) catalyst.

Hybrid Pluggable Processing Pipeline (HyP3): Programmatic Access to Cloud-Based Processing of SAR Data

Science.gov (United States)

Weeden, R.; Horn, W. B.; Dimarchi, H.; Arko, S. A.; Hogenson, K.

2017-12-01

A problem often faced by Earth science researchers is the question of how to scale algorithms that were developed against few datasets and take them to regional or global scales. This problem only gets worse as we look to a future with larger and larger datasets becoming available. One significant hurdle can be having the processing and storage resources available for such a task, not to mention the administration of those resources. As a processing environment, the cloud offers nearly unlimited potential for compute and storage, with limited administration required. The goal of the Hybrid Pluggable Processing Pipeline (HyP3) project was to demonstrate the utility of the Amazon cloud to process large amounts of data quickly and cost effectively. Principally built by three undergraduate students at the ASF DAAC, the HyP3 system relies on core Amazon cloud services such as Lambda, Relational Database Service (RDS), Elastic Compute Cloud (EC2), Simple Storage Service (S3), and Elastic Beanstalk. HyP3 provides an Application Programming Interface (API) through which users can programmatically interface with the HyP3 system; allowing them to monitor and control processing jobs running in HyP3, and retrieve the generated HyP3 products when completed. This presentation will focus on the development techniques and enabling technologies that were used in developing the HyP3 system. Data and process flow, from new subscription through to order completion will be shown, highlighting the benefits of the cloud for each step. Because the HyP3 system can be accessed directly from a user's Python scripts, powerful applications leveraging SAR products can be put together fairly easily. This is the true power of HyP3; allowing people to programmatically leverage the power of the cloud.

Highlights: • Dehydration of glucose as model compound to LA over Fe/HY zeolite catalyst. • RSM coupled with BBD for optimization of LA yield from glucose. • Optimization involving evaluation of four parameters gave 61.8% of optimum LA yield. • Direct conversion of OPF over Fe/HY zeolite yielded 17.6% LA with 54.8% efficiency. • Reusability of Fe/HY zeolite catalyst was tested for five successive cycles. - Abstract: Levulinic acid (LA) is a versatile chemical with numerous applications. In this study, the conversions of glucose and oil palm fronds (OPF) to LA have been conducted over 10% Fe/HY zeolite catalyst. The optimization of LA yield from glucose conversion using Box–Behnken design and response surface methodology reported 61.8% yield, which can be achieved at temperature 173.4 °C, reaction time 3.3 h, 0.93 g of glucose and 0.89 g 10% Fe/HY zeolite. The LA yield from OPF conversion conducted at the optimum conditions was 17.6% with 54.8% process efficiency. It was also observed that Fe leaching from 10% Fe/HY zeolite was insignificant and recycled 10% Fe/HY zeolite gave sufficient performance for five successive cycles. This study emphasizes the potential of Fe/HY zeolite catalyst for catalytic conversion of lignocellulosic biomass to LA

A expectativa de vida restante de um paciente ao iniciar HD é apenas cerca de um quarto daquela da população geral com a mesma idade. O esquema convencional de HD, com três sessões semanais de cerca de quatro horas, foi estabelecido de maneira empírica há cerca de quatro décadas e merece ser reavaliado criticamente. Desde a falha do Estudo HEMO em demonstrar benefícios clínicos com o aumento do Kt/V de ureia nos pacientes em esquema convencional de HD, tem havido um crescente interesse pelos esquemas alternativos de HD com o intuito de prover um tratamento associado com uma melhor sobrevida. Dentre os esquemas mais promissores, destacam-se a HD diária de curta duração e a HD noturna prolongada. As limitações econômicas que inibem a aplicação dos conhecimentos emergentes nesta área devem ser vencidas.The mortality rate among patients on hemodialysis (HD is extremely high. Remaining life expectancy for a patient initiating HD is only approximately one quarter of that of the general population at the same age bracket. The conventional HD regimen based on four-hour sessions three times a week was empirically established nearly four decades ago and needs to be revisited. Since the failure of the HEMO Study to demonstrate the clinical benefits of higher urea Kt/V for patients on conventional HD, an increasing interest for alternative HD regimens has emerged aiming at providing a treatment for improving survival rates. Short daily HD and long nocturnal HD stand out as the most promising alternative regimens. Economical obstacles which could hinder the clinical application of emerging knowledge in the field should be overcome.

HY-Specific Induced Regulatory T Cells Display High Specificity and Efficacy in the Prevention of Acute Graft-versus-Host Disease.

Naturally derived regulatory T cells (Tregs) may prevent graft-versus-host disease (GVHD) while preserving graft-versus-leukemia (GVL) activity. However, clinical application of naturally derived regulatory T cells has been severely hampered by their scarce availability and nonselectivity. To overcome these limitations, we took alternative approaches to generate Ag-specific induced Tregs (iTregs) and tested their efficacy and selectivity in the prevention of GVHD in preclinical models of bone marrow transplantation. We selected HY as a target Ag because it is a naturally processed, ubiquitously expressed minor histocompatibility Ag (miHAg) with a proven role in GVHD and GVL effect. We generated HY-specific iTregs (HY-iTregs) from resting CD4 T cells derived from TCR transgenic mice, in which CD4 cells specifically recognize HY peptide. We found that HY-iTregs were highly effective in preventing GVHD in male (HY(+)) but not female (HY(-)) recipients using MHC II-mismatched, parent→F1, and miHAg-mismatched murine bone marrow transplantation models. Interestingly, the expression of target Ag (HY) on the hematopoietic or nonhematopoietic compartment alone was sufficient for iTregs to prevent GVHD. Furthermore, treatment with HY-iTregs still preserved the GVL effect even against pre-established leukemia. We found that HY-iTregs were more stable in male than in female recipients. Furthermore, HY-iTregs expanded extensively in male but not female recipients, which in turn significantly reduced donor effector T cell expansion, activation, and migration into GVHD target organs, resulting in effective prevention of GVHD. This study demonstrates that iTregs specific for HY miHAgs are highly effective in controlling GVHD in an Ag-dependent manner while sparing the GVL effect.

The hydrodeoxygenation of a model compound of lignin-derived bio-oil, guaiacol, which can be obtained from the pyrolysis of biomass to bio-oil, has attracted considerable research attention because of its huge potential as a substitute for conventional fuels. In this study, platinum-loaded HY zeolites (Pt/HY) with different Si/Al molar ratios were used as catalysts for the hydrodeoxygenation of guaiacol, anisole, veratrole, and phenol to a range of hydrocarbons, such as cyclohexane. The cyclohexane (major product) yield increased with increasing number of acid sites. To produce bio-oil with the maximum level of cyclohexane and alkylated cyclohexanes, which would be suitable as a substitute for conventional transportation fuels, the Si/Al molar ratio should be optimized to balance the Pt particle-induced hydrogenation with acid site-induced methyl group transfer. The fuel properties of real bio-oil derived from the fast pyrolysis of cork oak was improved using the Pt/HY catalyst.

Multiscale Hy3S: Hybrid stochastic simulation for supercomputers

Directory of Open Access Journals (Sweden)

Kaznessis Yiannis N

2006-02-01

Full Text Available Abstract Background Stochastic simulation has become a useful tool to both study natural biological systems and design new synthetic ones. By capturing the intrinsic molecular fluctuations of "small" systems, these simulations produce a more accurate picture of single cell dynamics, including interesting phenomena missed by deterministic methods, such as noise-induced oscillations and transitions between stable states. However, the computational cost of the original stochastic simulation algorithm can be high, motivating the use of hybrid stochastic methods. Hybrid stochastic methods partition the system into multiple subsets and describe each subset as a different representation, such as a jump Markov, Poisson, continuous Markov, or deterministic process. By applying valid approximations and self-consistently merging disparate descriptions, a method can be considerably faster, while retaining accuracy. In this paper, we describe Hy3S, a collection of multiscale simulation programs. Results Building on our previous work on developing novel hybrid stochastic algorithms, we have created the Hy3S software package to enable scientists and engineers to both study and design extremely large well-mixed biological systems with many thousands of reactions and chemical species. We have added adaptive stochastic numerical integrators to permit the robust simulation of dynamically stiff biological systems. In addition, Hy3S has many useful features, including embarrassingly parallelized simulations with MPI; special discrete events, such as transcriptional and translation elongation and cell division; mid-simulation perturbations in both the number of molecules of species and reaction kinetic parameters; combinatorial variation of both initial conditions and kinetic parameters to enable sensitivity analysis; use of NetCDF optimized binary format to quickly read and write large datasets; and a simple graphical user interface, written in Matlab, to help users

Full Text Available Abstract Background Array-based comparative genomic hybridization (CGH and gene expression profiling have become vital techniques for identifying molecular defects underlying genetic diseases. Regardless of the microarray platform, cyanine dyes (Cy3 and Cy5 are one of the most widely used fluorescent dye pairs for microarray analysis owing to their brightness and ease of incorporation, enabling high level of assay sensitivity. However, combining both dyes on arrays can become problematic during summer months when ozone levels rise to near 25 parts per billion (ppb. Under such conditions, Cy5 is known to rapidly degrade leading to loss of signal from either "homebrew" or commercial arrays. Cy5 can also suffer disproportionately from dye photobleaching resulting in distortion of (Cy5/Cy3 ratios used in copy number analysis. Our laboratory has been active in fluorescent dye research to find a suitable alternative to Cy5 that is stable to ozone and resistant to photo-bleaching. Here, we report on the development of such a dye, called HyPer5, and describe its' exceptional ozone and photostable properties on microarrays. Results Our results show HyPer5 signal to be stable to high ozone levels. Repeated exposure of mouse arrays hybridized with HyPer5-labeled cDNA to 300 ppb ozone at 5, 10 and 15 minute intervals resulted in no signal loss from the dye. In comparison, Cy5 arrays showed a dramatic 80% decrease in total signal during the same interval. Photobleaching experiments show HyPer5 to be resistant to light induced damage with 3- fold improvement in dye stability over Cy5. In high resolution array CGH experiments, HyPer5 is demonstrated to detect chromosomal aberrations at loci 2p21-16.3 and 15q26.3-26.2 from three patient sample using bacterial artificial chromosome (BAC arrays. The photostability of HyPer5 is further documented by repeat array scanning without loss of detection. Additionally, HyPer5 arrays are shown to preserve sensitivity and

HySafe - The Network of Excellence for Hydrogen Safety

International Nuclear Information System (INIS)

Jordan, T.

2006-01-01

Safety always has been a critical issue for innovations as it influences the economic attractiveness and public acceptance of any new idea. Furthermore, a fair market for trading innovative products has to be based on homogenized legal regulations, which usually refer commonly accepted standards. Ideally, these standards should be the unique outcome of safety assessments, based on profound and concerted pre-normative research work. However, in Europe the research related to hydrogen safety is still fragmented. This was the reason for the European Commission to support the needed integration and focusing of the related efforts with the help of a new instrument, the so-called Networks of Excellence NoE. So, the goal of NoE HySafe is to provide the basis to facilitate the safe introduction of hydrogen as an energy carrier, by removing the described safety related obstacles. The network is constituted by 24 partners from 12 European countries and from Canada, representing private industries, especially from the automotive sector, universities and research institutions. More than 120 scientists perform integrative work in 15 work packages. A biennial report on Hydrogen Safety is going to be published, the available experimental facilities have been catalogued and qualified, educational programs are designed. After the first successful International Conference on Hydrogen Safety the second will be organized 2007 in San Sebastian, Spain. The European codes and standards activities will be supported by scientifically based information formulated in the HySafe position papers. The web-site www.hysafe.net offers a versatile platform for internal and external communication. The further work program is orientated not only at the results of a state-of-the-art report and a PIRT analysis performed within the NoE but also complies with the needs identified in the external network including other European projects related to hydrogen like StorHy, HyWays and NATURALHY.

Laser-driven planar impact of miniature specimens of HY-100 steel

International Nuclear Information System (INIS)

Alexander, David J.; Robbins, David L.

2002-01-01

The deformation and fracture behavior of HY-100, a high-strength steel, under high strain-rate planar-impact conditions, has been studied with the Laser-Driven Miniflyer apparatus. Cold-rolled copper flyers 3 mm in diameter and either 50 or 100 microns thick have been laser-launched against HY-100 targets, 200 microns thick and nominally 10 mm square. The target specimens were sectioned from the 25-mm-thick HY-100 plate in three mutually perpendicular orientations, either parallel or perpendicular to the plate rolling direction. The back-surface response of the HY-100 targets was monitored with dual VISARs. The flyer velocity was varied to produce a range of behavior, from deformation at low velocities, to damage formation at intermediate velocities, and finally to complete spall failure at the highest velocities. The target specimens were sectioned after testing to examine the microstructure and failure processes of the deformed material. Spall strengths were calculated from the VISAR signals. The VISAR traces showed well-defined elastic precursors, which were similar for all orientations of the specimens. The spall strengths, as estimated from the magnitude of the pullback signal, were also similar for all three orientations. The spall strength increased as the flyer impact velocity increased, to values of about 4.6 GPa. Metallographic examination revealed that damage occurred at lower impact velocities in specimens loaded in the through-thickness direction of the plate, as compared to specimens oriented parallel to the plate thickness, but this difference was not reflected in the pull-back signal or the spall strengths

Fallopian tube patency testing is an essential part of infertility evaluation. Hysterosalpingo-contrast sonography (HyCoSy) has been described as reliable, well tolerated and safe compared to other modalities such as laparoscopy and a dye test or hysterosalpingography. Limited availability of the previously used contrast has led to the introduction of a foam contrast agent as an alternative. To assess the tolerability, safety and occurrence of pregnancy post-procedure of hysterosalpingo-foam sonography (HyFoSy). A retrospective cohort study of women who had a HyFoSy at Queensland Ultrasound for Women from March 2013 to February 2015. A questionnaire was sent to their referring doctor to identify any complications or subsequent pregnancies with or without artificial reproductive technology (ART) within six months of the HyFoSy. Of 200 women, four cases were abandoned due to difficulty introducing the intracervical catheter, severe discomfort or a vasovagal episode. Response from referring doctors for 155 women reported no post-procedural complication. One hundred and eleven women were followed up for at least six months. Twenty-four out of 59 women (40.7%) who had ART and 24 out of 52 women (46.2%) who did not have ART conceived. Fifty percent of women who were nulligravida at the time of investigation, found to have at least one patent fallopian tube, whose partner had a normal semen analysis, spontaneously conceived within the time of follow up. HyFoSy is well tolerated and safe. A preponderance of pregnancies in the first month after HyFoSy suggests that a therapeutic effect may exist. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

A hybrid Rankine cycle (HyRC) with ambient pressure combustion (APC)

International Nuclear Information System (INIS)

Wu, Lijun; Thimsen, David; Clements, Bruce; Zheng, Ligang; Pomalis, Richard

2014-01-01

The main losses in thermal power generation include heat in exhaust flue gas, heat rejected through steam condensation of low-pressure turbine, and exergy destruction in heat exchange process etc. To the extent that the heat losses are significantly greater in temperature than either air or water coolant resources, these losses also represent exergy losses which might be exploited to improve plant capacity and efficiency. This paper presents a hybrid Rankine cycle (HyRC) with an ambient pressure combustion (APC) boiler to address the recovery potential of these losses within the steam Rankine cycle (SRC). The APC–HyRC concept employs an organic Rankine cycle (ORC) to supplement SRC and to reduce cycle energy losses to the atmosphere since organic fluids are capable of lowering cycle condensation temperature when a very low temperature heat sink is available. The case studies based on a 399 MW SRC unit show that the APC–HyRC configurations have better thermodynamic performance than its base case SRC at a cycle condensation temperature of 30 °C and below. The best APC–HyRC configuration generates up to 14% more power than the baseline steam cycle which is a 5.45% increase in overall gross efficiency with a cycle condensation temperature at 4 °C. - Highlights: • A hybrid Rankine cycle with water and organic fluid is presented. • Heat losses in exhaust flue gas and exhaust steam are reduced. • Exergy losses in regeneration process are reduced. • Efficiency improvements are made to the conventional steam Rankine cycle. • Issues in design/construction of greenfield and repowering project are discussed

An aciduric high-yielding hydrogen yeast named Candida maltosa HY-35 was screened, which can grow and produce hydrogen at pH 1.3. Further research was carried out batchwise to measure the hydrogen-producing ability of a mixed culture of C. maltosa HY-35 and a facultative anaerobe Enterobacter aerogenes W-23. In this method, with the mixed culture of these two strains at 35 {sup circle} C for 28 h, the hydrogen yield was 1735 ml/l, which was 17.15% and 119.90% higher than those of the monoculture of E. aerogenes W-23 and C. maltosa HY-35, respectively. Meanwhile, the average hydrogen production rate with the mixed culture was 261.1 ml/h/l, which was 7.85% and 146.23% higher than those of the monoculture of E. aerogenes W-23 and C. maltosa HY-35, respectively. The results suggested that mixed culture of these two strains had the synergistic effect on hydrogen production. The optimum fermentation medium and operation conditions for hydrogen production with mixed culture were also investigated. (author)

2008-12-01

This report summarizes a multi-year Directed Technologies Inc. (DTI) project to study the build-out of hydrogen production facilities during the transition from gasoline internal combustion engine vehicle to hydrogen fuel cell vehicles. The primary objectives of the project are to develop an enhanced understanding of hydrogen production issues during the transition period (out to 2050) and to develop recommendations for the DOE on areas of further study. These objectives are achieved by conducting economic and scenario analysis to predict how industry would provide the hydrogen production, delivery and dispensing capabilities necessary to satisfy increased hydrogen demand. The primary tool used for the analysis is a custom created MatLab simulation tool entitled HyPro (short for Hydrogen Production). This report describes the calculation methodology used in HyPro, the baseline assumptions, the results of the baseline analysis and several corollary studies. The appendices of this report included a complete listing of model assumptions (capital costs, efficiencies, feedstock prices, delivery distances, etc.) and a step-by-step manual on the specific operation of the HyPro program. This study was made possible with funding from the U.S. Department of Energy (DOE).

Mediterranean Hydrogen Solar (MedHySol) is a federator project for development of a massive hydrogen production starting from solar energy and its exportation within a framework of a Euro-Maghrebian Cooperation project for industrial and energetic needs in the Mediterranean basin. The proposal of this project is included in the Algiers Declaration's on Hydrogen from Renewable Origin following the organization of the first international workshop on hydrogen which was held in 2005. Algeria is the privileged site to receive the MedHySol platform. The objective of the first step of the project is to realize a technological platform allowing the evaluation of emergent technologies of hydrogen production from solar energy with a significant size (10-100 kW) and to maintain the development of energetic rupture technologies. The second step of the project is to implement the most effective and less expensive technologies to pilot great projects (1-1000 MW). In this article we present the potentialities and the feasibility of MedHySol, as well as the fundamental elements for a scientific and technical supervision of this great project. (author)

Full Text Available Com o objetivo de testar materiais alternativos para cama de aviário na criação de frangos de corte, foram alojados seis lotes consecutivos, cada um contendo 5.600 aves, apenas fêmeas, distribuídas em 35 boxes. Os tratamentos consistiram de sete tipos de material para cama (maravalha; casca de arroz; sabugo de milho triturado; capim-cameron picado; palhada de soja picada; resto da cultura do milho picado; e serragem, cada um com cinco repetições. Avaliaram-se nas aves o peso corporal médio e o consumo médio de ração e, nas camas, os teores de N, Ca, P e pH. Observaram-se ainda a presença de salmonela, a contagem de oocistos de eimeria na cama e o escore de lesões no intestino das aves ao abate. A utilização dos materiais alternativos avaliados como cama de aviário, por seis lotes consecutivos, como alternativas à maravalha não prejudicou o desempenho de frangos de corte. Esses materiais, após o descarte, por apresentarem valor em minerais superior ao da maravalha, podem ser utilizados na adubação de culturas.Aiming to evaluate alternative materials to be used as broiler litter reutilization, six consecutive lots of 5,600 female broilers were allocated to 35 pens. The treatments consisted of seven types of litter materials: wood shavings, rice husk, ground corncob, chopped camerongrass, chopped soybean straw, chopped corn stalk and sawdust, each one with five replications. In the birds, it was evaluated the average body weight, feed consumption and in the litter, it was evaluated the contents of N, Ca, P and pH. The presence of salmoella, the eimeria oocists counting in the litter, and the gut birds lesions score at slaughter were also observed. The use of alternative materials evaluated as litter, per six concecutive lots, as a alternative for wood shavings did no prejudice the performance of broilers. These materials, by presenting mineral values higher than wood shavings, after discarding, could be used as culture

Full Text Available Após sucessivos anos, aplicações do herbicida glyphosate em pomares de citros no Estado de São Paulo selecionaram biótipos resistentes de Conyza bonariensis e C. canadensis. Na ocorrência de plantas daninhas resistentes em uma área agrícola, tornam-se necessárias mudanças nas práticas de manejo para obtenção de adequado controle das populações resistentes, bem como para a redução da pressão de seleção sobre outras espécies. Assim, este trabalho foi realizado com o objetivo de identificar herbicidas alternativos para controle de biótipos de Conyza spp. resistentes ao herbicida glyphosate, com aplicações em diferentes estádios fenológicos da planta daninha. Três experimentos foram conduzidos em campo, em pomares de citros em formação, sobre plantas de buva em estádio fenológico de dez folhas e no pré-florescimento. Para plantas no estádio de dez folhas, controle satisfatório foi obtido com aplicações de glyphosate + bromacil + diuron (1.440 + 1.200 + 1.200 g ha-1, glyphosate + atrazina (1.440 + 1.500 g ha-1 e glyphosate + diuron (1.440 + 1.500 g ha-1. Quando em estádio de pré-florescimento de Conyza spp., a aplicação do herbicida amônio-glufosinato, na dose de 400 g ha-1, isolado ou associado a MSMA, bromacil+diuron, metsulfuron, carfentrazone e paraquat, foi a alternativa viável para controle dos biótipos resistentes ao glyphosate.After successive years, glyphosate applications on São Paulo-Brazil citrus orchards selected resistant biotypes of Conyza bonariensis and C. canadensis. The occurrence of herbicide-resistant weed biotypes at some agricultural area makes it necessary to change the management practices to reach effective control of the selected resistant populations, as well as to reduce selection pressure on the other species. Thus, this work aimed to identify the alternative herbicides to control glyphosate-resistant biotypes of Conyza spp., with applications at different weed phenological

Hybrid Pluggable Processing Pipeline (HyP3): A cloud-based infrastructure for generic processing of SAR data

Science.gov (United States)

Hogenson, K.; Arko, S. A.; Buechler, B.; Hogenson, R.; Herrmann, J.; Geiger, A.

2016-12-01

A problem often faced by Earth science researchers is how to scale algorithms that were developed against few datasets and take them to regional or global scales. One significant hurdle can be the processing and storage resources available for such a task, not to mention the administration of those resources. As a processing environment, the cloud offers nearly unlimited potential for compute and storage, with limited administration required. The goal of the Hybrid Pluggable Processing Pipeline (HyP3) project was to demonstrate the utility of the Amazon cloud to process large amounts of data quickly and cost effectively, while remaining generic enough to incorporate new algorithms with limited administration time or expense. Principally built by three undergraduate students at the ASF DAAC, the HyP3 system relies on core Amazon services such as Lambda, the Simple Notification Service (SNS), Relational Database Service (RDS), Elastic Compute Cloud (EC2), Simple Storage Service (S3), and Elastic Beanstalk. The HyP3 user interface was written using elastic beanstalk, and the system uses SNS and Lamdba to handle creating, instantiating, executing, and terminating EC2 instances automatically. Data are sent to S3 for delivery to customers and removed using standard data lifecycle management rules. In HyP3 all data processing is ephemeral; there are no persistent processes taking compute and storage resources or generating added cost. When complete, HyP3 will leverage the automatic scaling up and down of EC2 compute power to respond to event-driven demand surges correlated with natural disaster or reprocessing efforts. Massive simultaneous processing within EC2 will be able match the demand spike in ways conventional physical computing power never could, and then tail off incurring no costs when not needed. This presentation will focus on the development techniques and technologies that were used in developing the HyP3 system. Data and process flow will be shown

2006-01-01

HyWays is an integrated project, co-funded by research institutes, industry, national agencies and by the European Commission under the 6. Framework Programme. HyWays aims to develop a validated and well accepted Road-map for the introduction of hydrogen in the European energy system. The main characteristic of this Road-map is that it reflects real life conditions by taking into account not only technological but also country specific institutional, geographic and socio/economic barriers and opportunities. Both stationary and mobile applications are addressed, including possible synergies ('spill over effects') between these applications. HyWays will systematically describe the future steps to be taken for large-scale introduction of hydrogen as an energy carrier in the power market and transport sector and as a storage medium for renewable energy. An Action Plan for the support of the introduction of hydrogen technologies will be derived from this Road-map. (authors)

Analysis of fast neutron-generated mutants at the Arabidopsis thaliana HY4 locus

International Nuclear Information System (INIS)

Bruggemann, E.; Handwerger, K.; Essex, C.; Storz, G.

1996-01-01

Ionizing radiation is expected to produce mutants with deletions or other chromosomal rearrangements. These mutants are useful for a variety of purposes, such as creating null alleles and cloning genes whose existence is known only from their mutant phenotype; however, only a few mutations generated by ionizing radiation have been characterized at the molecular level in Arabidopsis thaliana. Twenty fast neutron-generated alleles of the Arabidopsis HY4 locus, which encodes a blue light receptor, CRY1, were isolated and characterized. Nine of the mutant alleles displayed normal genetic behavior. The other 11 mutant alleles were poorly transmitted through the male gametophyte and were lethal in homozygous plants. Southern blot analysis demonstrated that alleles of the first group generally contain small or moderate-sized deletions at HY4, while alleles of the second group contain large deletions at this locus. These results demonstrate that fast neutrons can produce a range of deletions at a single locus in Arabidopsis. Many of these deletions would be suitable for cloning by genomic subtraction or representational difference analysis. The results also suggest the presence of an essential locus adjacent to HY4.

Genetic interaction of two abscisic acid signaling regulators, HY5 and FIERY1, in mediating lateral root formation

KAUST Repository

Chen, Hao

2011-01-01

Root architecture is continuously shaped in a manner that helps plants to better adapt to the environment. Gene regulation at the transcriptional or post-transcriptional levels largely controls this environmental response. Recently, RNA silencing has emerged as an important player in gene regulation and is involved in many aspects of plant development, including lateral root formation. In a recent study, we found that FIERY1, a bifunctional abiotic stress and abscisic acid (ABA) signaling regulator and an endogenous RNA silencing suppressor, mediates auxin response during lateral root formation in Arabidopsis. We proposed that FRY1 regulates lateral root development through its activity on adenosine 3,5-bisphosphate (PAP), a strong inhibitor of exoribonucleases (XRNs). Interestingly, some of the phenotypes of fry1, such as enhanced response to light in repressing hypocotyl elongation and hypersensitivity to ABA in lateral root growth, are opposite to those of another light- and ABA-signaling mutant, hy5. Here we analyzed the hy5 fry1 double mutant for root and hypocotyl growth. We found that the hy5 mutation can suppress the enhanced light sensitivity in fry1 hypocotyl elongation and restore the lateral root formation. The genetic interaction between HY5 and FRY1 indicates that HY5 and FRY1 may act in overlapping pathways that mediate light signaling and lateral root development. © 2011 Landes Bioscience.

Formation of defect-fluorite structured NdNiOxHy epitaxial thin films via a soft chemical route from NdNiO3 precursors.

Science.gov (United States)

Onozuka, T; Chikamatsu, A; Katayama, T; Fukumura, T; Hasegawa, T

2016-07-26

A new phase of oxyhydride NdNiOxHy with a defect-fluorite structure was obtained by a soft chemical reaction of NdNiO3 epitaxial thin films on a substrate of SrTiO3 (100) with CaH2. The epitaxial relationship of this phase relative to SrTiO3 could be controlled by changing the reaction temperature. At 240 °C, NdNiOxHy grew with a [001] orientation, forming a thin layer of infinite-layer NdNiO2 at the interface between the NdNiOxHy and the substrate. Meanwhile, a high-temperature reaction at 400 °C formed [110]-oriented NdNiOxHy without NdNiO2.

The production of anthocyanin is regulated by light and corresponding photoreceptors. In this study, we found that exposure to blue light and overexpression of CRY1a are associated with increased accumulation of anthocyanin in tomato (Solanum lycopersicum L.). These responses are the result of changes in mRNA and the protein levels of SlHY5, a transcription factor. In vitro and in vivo experiments using EMSA and ChIP-qPCR assays revealed that SlHY5 could directly recognize and bind to the G-box and ACE motifs in the promoters of anthocyanin biosynthesis genes, such as CHS1, CHS2 and DFR. Silencing of SlHY5 in OE-CRY1a lines decreased the accumulation of anthocyanin. The findings presented here not only deepened our understanding of how light controls anthocyanin biosynthesis and associated photoprotection in tomato leaves, but also allowed us to explore potential targets for improving pigment production.

Full Text Available The first Chinese operational Ku-band scatterometer on board Haiyang-2A (HY-2A, launched in August 2011, is designed for monitoring the global ocean surface wind. This study estimates the quality of the near-real-time (NRT retrieval wind speed and wind direction from the HY-2A scatterometer for 36 months from 2012 to 2014. We employed three types of sea-surface wind data from oceanic moored buoys operated by the National Data Buoy Center (NDBC and the Tropical Atmospheric Ocean project (TAO, the European Centre for Medium Range Weather Forecasting (ECMWF reanalysis data (ERA-Interim, and the advanced scatterometer (ASCAT to calculate the error statistics including mean bias, root mean square error (RMSE, and standard deviation. In addition, the rain effects on the retrieval winds were investigated using collocated Climate Prediction Center morphing method (CMORPH precipitation data. All data were collocated with the HY-2A scatterometer wind data for comparison. The quality performances of the HY-2A NRT wind vectors data (especially the wind speeds were satisfactory throughout the service period. The RMSEs of the HY-2A wind speeds relative to the NDBC, TAO, ERA-Interim, and ASCAT data were 1.94, 1.73, 2.25, and 1.62 m·s−1, respectively. The corresponding RMSEs of the wind direction were 46.63°, 43.11°, 39.93°, and 47.47°, respectively. The HY-2A scatterometer overestimated low wind speeds, especially under rainy conditions. Rain exerted a diminishing effect on the wind speed retrievals with increasing wind speed, but its effect on wind direction was robust at low and moderate wind speeds. Relative to the TAO buoy data, the RMSEs without rain effect were reduced to 1.2 m·s−1 and 39.68° for the wind speed direction, respectively, regardless of wind speed. By investigating the objective laws between rain and the retrieval winds from HY-2A, we could improve the quality of wind retrievals through future studies.

Introducing zinc cations into zeolite Y via the reduction of HY with zinc metal vapour

Science.gov (United States)

Seidel, A.; Boddenberg, B.

1996-01-01

Zeolites HY and NaY which were contacted with zinc metal vapour at 420°C were investigated by carbon monoxide and xenon adsorption as well as 129Xe NMR spectroscopy. The reaction of zeolite HY results in the incorporation of Zn 2+ cations which are shown to populate the supercage positions S II and S III to an unusually high extent. The supercage zinc cation concentration strongly decreases when the material is saturated with water and subsequently dehydrated at 400°C. The zeolite NaY turns out to be inert towards the reaction with zinc metal vapour.

Insights into the HyPer biosensor as molecular tool for monitoring cellular antioxidant capacity

Directory of Open Access Journals (Sweden)

Helen Hernández

2018-06-01

Full Text Available Aerobic metabolism brings inexorably the production of reactive oxygen species (ROS, which are counterbalanced by intrinsic antioxidant defenses avoiding deleterious intracellular effects. Redox balance is the resultant of metabolic functioning under environmental inputs (i.e. diet, pollution and the activity of intrinsic antioxidant machinery. Monitoring of intracellular hydrogen peroxide has been successfully achieved by redox biosensor advent; however, to track the intrinsic disulfide bond reduction capacity represents a fundamental piece to understand better how redox homeostasis is maintained in living cells.In the present work, we compared the informative value of steady-state measurements and the kinetics of HyPer, a H2O2-sensitive fluorescent biosensor, targeted at the cytosol, mitochondrion and endoplasmic reticulum. From this set of data, biosensor signal recovery from an oxidized state raised as a suitable parameter to discriminate reducing capacity of a close environment. Biosensor recovery was pH-independent, condition demonstrated by experiments on pH-clamped cells, and sensitive to pharmacological perturbations of enzymatic disulfide reduction. Also, ten human cell lines were characterized according their H2O2-pulse responses, including their capacity to reduce disulfide bonds evaluated in terms of their migratory capacity.Finally, cellular migration experiments were conducted to study whether migratory efficiency was associated with the disulfide reduction activity. The migration efficiency of each cell type correlates with the rate of signal recovery measured from the oxidized biosensor. In addition, HyPer-expressing cells treated with N-acetyl-cysteine had accelerated recovery rates and major migratory capacities, both reversible effects upon treatment removal. Our data demonstrate that the HyPer signal recovery offers a novel methodological tool to track the cellular impact of redox active biomolecules. Keywords: Antioxidant

Full Text Available El artículo que se presenta caracteriza al turismo como una distinción de la modernidad, desde la teoría de Niklas Luhmann. Para tal efecto se asume que la modernidad es una autodescripción de la sociedad funcionalmente diferenciada, en la cual el turismo actúa como un medio que hace posible acoplar distintos sistemas funcionales para su ejecución. Sobre esta base, se identifica el acoplamiento que logra el turismo entre el sistema económico y el de los medios masivos de comunicación, y se mencionan los dos modelos a los que ha dado lugar: el turismo de masas y el alternativo. Se concluye que dichos modelos no necesariamente son consecutivos, aunque sí presentan una forma diferenciada de practicar el turismo.

RECOMBINANT FLUORESCENT SENSOR OF HYDROGEN PEROXIDE HyPer FUSED WITH ADAPTOR PROTEIN Ruk/CIN85: DESIGNING OF EXPRESSION VECTOR AND ITS FUNCTIONAL CHARACTERIZATION

2015-10-01

Full Text Available The aim of this study was to design the expression vector encoding fluorescent sensor of hydrogen peroxide HyPer fused with adaptor protein Ruk/CIN85 as well as to check its subcellular distribution and ability to sense hydrogen peroxide. It was demonstrated that in transiently transfected HEK293 and MCF-7 cells Ruk/CIN85-HyPer is concentrated in dot-like vesicular structures of different size while HyPer is diffusely distributed throughout the cell. Using live cell fluorescence microscopy we observed gradual increase in hydrogen peroxide concentration in representative vesicular structures during the time of experiment. Thus, the developed genetic construction encoding the chimeric Ruk/CIN85-HyPer fluorescent protein represents a new tool to study localized H2O2 production in living cells.

To evaluate the surface and microstructural alterations of new and used HyFlex EDM prototypes and to test their fatigue resistance. Fifteen HyFlex EDM prototypes were used for in vitro instrumentation of severely curved root canals. Surface and microstructural characteristics of new and used files were compared by ESEM analysis equipped with energy dispersive X-ray spectrophotometry (EDS) and optical metallographic imaging. Usage-induced degradation was assessed. Thirty additional HyFlex EDM prototypes and 20 standard manufactured HyFlex CM files were subjected to cyclic fatigue tests. Time to fracture was recorded, and results were validated using the Kruskal-Wallis test (α-level 0.05). Fatigued files were analysed by ESEM for fractographic evaluation. Surface and microstructural characterization of EDM prototypes revealed the typical spark-machined surface of a NiTi EDM alloy. No fractures were registered during root canal instrumentation. No evident surface alterations and minor degradation were observed between new and used instruments. The metallographic analysis of new and used files disclosed a homogeneous structure, mostly composed of lenticular martensite grains, and some residual austenite. The cyclic fatigue test showed an increase of fatigue resistance up to 700% on the EDM compared to CM files. Spark-machined peculiar surface is the main feature of HyFlex EDM. Low degradation was observed after multiple canal instrumentations. Prototypes exhibited surprising high values of cyclic fatigue resistance and a safe in vitro use in severely curved canals. © 2015 International Endodontic Journal.

Casas , Andrés Fernando

2003-06-01

Full Text Available Este ensayo revisa diferentes aproximaciones de la teoría económica para evaluar estados sociales alternativos, a partir de la formulación de una función de bienestar social que admita o niegue comparaciones interpersonales de utilidad. Analiza en especial los puntos de vista de la vieja y la nueva economía del bienestar. Y concluye que con los aportes de Amartya Sen al concepto de bienestar como funcionamiento y al de justicia como capacidad de elegir entre diversos funcionamientos, es posible considerar de manera distinta a los agentes y evaluar opciones alternativas de condiciones de vida.

HyGenSys: a Flexible Process for Hydrogen and Power Production with Reduction of CO2 Emission HyGenSys : un procédé flexible de production d’hydrogène et d’électricité avec réduction des émissions de CO2

Directory of Open Access Journals (Sweden)

Giroudière F.

2010-09-01

Full Text Available This paper presents the latest development of HyGenSys, a new sustainable process and technology for the conversion of natural gas to hydrogen and power. The concept combines a specific steam reforming reactor-exchanger with a gas turbine. The heat necessary for the steam reforming reaction comes from hot pressurized flue gases produced in a gas turbine instead of a conventional furnace. Thanks to this high level of heat integration, the overall efficiency is improved and the natural gas consumption is reduced which represents an advantage with regard to economics and CO2 emission reduction. In addition to the efficient HyGenSys process scheme itself, the technology of the reactorexchanger also offers a high level of heat integration for even more energy saving. Two main alternatives are examined in order to meet two different requirements. The first one, named HyGenSys-0, focuses on the hydrogen production for the refining and petrochemical application. The second one named HyGenSys-1, concerns the centralized power production with pre-combustion CO2capture. In that case, the produced hydrogen is fully used to fuel a power gas turbine. HyGenSys-1 has been developed and optimised in CACHET, a European Community funded project. The CACHET electrical power objective was 400 MW at the minimum. HyGenSys-0 and HyGenSys-1 are described in detail with challenges and advantages compared to existing technologies. For both alternatives, the heart of the technology is the reactor-exchanger. The reactor-exchanger design relies on an innovative arrangement of bayonet tubes that allows, at large scale, multiple heat exchanges between hot pressurized flue gas, natural gas feed and hydrogen rich stream produced. Cet article présente les développements récents d’HyGenSys, nouvel éco-procédé de conversion du gaz naturel en hydrogène et électricité. Le concept combine un réacteur-échangeur spécifique de reformage à la vapeur avec une turbine à gaz

The Hypersonic Materials Environmental Test System (HyMETS) arc-jet facility located at the NASA Langley Research Center in Hampton, Virginia, is primarily used for the research, development, and evaluation of high-temperature thermal protection systems for hypersonic vehicles and reentry systems. In order to improve testing capabilities and knowledge of the test article environment, an effort is underway to computationally simulate the flow-field using computational fluid dynamics (CFD). A detailed three-dimensional model of the arc-jet nozzle and free-jet portion of the flow-field has been developed and compared to calibration probe Pitot pressure and stagnation-point heat flux for three test conditions at low, medium, and high enthalpy. The CFD model takes into account uniform pressure and non-uniform enthalpy profiles at the nozzle inlet as well as catalytic recombination efficiency effects at the probe surface. Comparing the CFD results and test data indicates an effectively fully-catalytic copper surface on the heat flux probe of about 10% efficiency and a 2-3 kpa pressure drop from the arc heater bore, where the pressure is measured, to the plenum section, prior to the nozzle. With these assumptions, the CFD results are well within the uncertainty of the stagnation pressure and heat flux measurements. The conditions at the nozzle exit were also compared with radial and axial velocimetry. This simulation capability will be used to evaluate various three-dimensional models that are tested in the HyMETS facility. An end-to-end aerothermal and thermal simulation of HyMETS test articles will follow this work to provide a better understanding of the test environment, test results, and to aid in test planning. Additional flow-field diagnostic measurements will also be considered to improve the modeling capability.

Lee, Young Jin; Park, Ji Won; Hwang, Moon Kyu

2007-01-01

Hydrogen is being promoted as the energy-carrier for the future under the proposed hydrogen economy. As large reservoirs of hydrogen molecules do not exist in nature, the hydrogen needs to be produced using other energies such as nuclear, coal, natural gas, etc. The nuclear hydrogen production facility, where nuclear power is used to split water to produce hydrogen molecules, is presented as one of the optimal solutions for the large scale hydrogen production. Compared to other large scale hydrogen production methods, the nuclear hydrogen production can have better overall economics and less damaging environmental impacts such as global warming and pollution. In order to assess the overall economics of the hydrogen production, it is important to assess the hydrogen production efficiencies. In the conceptual design stage of the plant, various different plant layouts need to be studied to optimize the production efficiency. The main development aim of the HyPEP (Hydrogen Production Efficiency calculator Program) is the rapid assessment of the overall hydrogen production efficiency of a nuclear hydrogen production facility. The program is being developed with extensive GUI features to enhance the user-friendliness and the rapid model build-ups. This paper presents the current status of the development of HyPEP especially the GUI. HyPEP is being developed under an International Nuclear Engineering Research Initiative (I-NERI) Project

The HY-DE Model: An Interdisciplinary Attempt to Deal with the Phenomenon of Hyperattention

2015-10-01

Full Text Available As academics, as parents, as members of generation X, we cannot afford to ignore that the young generations that have been socialized in information society (generations Y and Z that I call "bit generations" diverge from their seniors not only in lifestyle and mentality, but they also follow new paths as regards cognitive (and thus learning processes. International research indicates that the accelerating development of digital devices results in changing habits of information consumption in a matter of a few years. The above changes, perceptible in information society, set me thinking, which, in turn, led me to devising a method based on what I call the HY-DE model. (1 The method I developed invites those who are interested, into the realm of teaching methodology. It is meant to deal with a logical but problematic, nevertheless not at all useless development of digital-world multitasking: hyperattention. The HY-DE-model method I constructed and wish to deploy as a corrective in the fashion described below is meant to tame and harness this phenomenon so that deep attention, which hyperattention suppresses in the electronic learning process, could again be liberated from the prison-house of hyperattention. But the latter, rather than diminishing or even discarding it, should also be regarded as a necessary tool if its positive aspect is recognized and even trained and cultivated as hyperattention is also necessary in coping with an overwhelming flood of information. Thus, in general, the HY-DE-model approach, with all the difference it represents, falls in line with the widespread research that engages the problematic of teaching and education in knowledge-based information society, trying to exploit the possibilities offered by a ceaselessly changing technical environment and put them to the service of effective learning and knowledge. (1 "HY-DE" is a term that I constructed from the first syllables of hyper and deep attention.

Full Text Available O artigo examina a falência da Associação dos Produtores Alternativos (APA de Ouro Preto do Oeste, em Rondônia, buscando identificar elementos estruturantes e explicativos das relações entre atores locais e evidenciando seus próprios quadros interpretativos. A partir de um breve histórico da implantação do Projeto Integrado de Colonização (PIC Ouro Preto do Oeste, são destacadas a origem social dos colonos, sua cultura política e o tipo de capital social construído nos assentamentos. Por outro lado, apresenta-se a lógica das instituições envolvidas no desenvolvimento desse projeto. As relações entre os diversos atores institucionais são apresentadas como uma rede multiconectada, unindo os níveis local, regional, nacional e internacional. A análise mostra o descompasso entre a visão econômica das instituições de apoio, voltadas para a produção, e as aspirações dos produtores da APA. Ao final, concluímos que a falência pode estar associada a dois fatores interligados: a 'desconfiança' dos produtores da APA em relação aos órgãos de apoio à agricultura familiar (Comissão Executiva do Plano da Lavoura Cacaueira, Agência de Defesa Sanitária Agrosilvopastoril do Estado de Rondônia, Empresa de Assistência Técnica e Extensão Rural e a ausência dos governos estadual e municipal no grupo de atores do sistema de redes multiconectadas, no qual poderiam ter desempenhado um papel de mediadores entre aquelas diferentes aspirações. Finalmente, a questão colocada relativiza a noção de 'fracasso' associada à falência.

Prefoldins Negatively Regulate Cold Acclimation in Arabidopsis thaliana by Promoting Nuclear Proteasome-Mediated HY5 Degradation.

The process of cold acclimation is an important adaptive response whereby many plants from temperate regions increase their freezing tolerance after being exposed to low non-freezing temperatures. The correct development of this response relies on proper accumulation of a number of transcription factors that regulate expression patterns of cold-responsive genes. Multiple studies have revealed a variety of molecular mechanisms involved in promoting the accumulation of these transcription factors. Interestingly, however, the mechanisms implicated in controlling such accumulation to ensure their adequate levels remain largely unknown. In this work, we demonstrate that prefoldins (PFDs) control the levels of HY5, an Arabidopsis transcription factor with a key role in cold acclimation by activating anthocyanin biosynthesis, in response to low temperature. Our results show that, under cold conditions, PFDs accumulate into the nucleus through a DELLA-dependent mechanism, where they interact with HY5, triggering its ubiquitination and subsequent degradation. The degradation of HY5 would result, in turn, in anthocyanin biosynthesis attenuation, ensuring the accurate development of cold acclimation. These findings uncover an unanticipated nuclear function for PFDs in plant responses to abiotic stresses. Copyright © 2017 The Author. Published by Elsevier Inc. All rights reserved.

Alternative interpretation of infrared spectra of the zeolite NaHY and 1-butene system

Energy Technology Data Exchange (ETDEWEB)

Foerster, H.; Seelemann, R.

1979-01-01

A Fourier transform IR study of the adsorption and isomerization of n-butenes on type A zeolites showed an essential similarity of the IR spectra of pure 1-butene absorbed on NaY and NaA zeolites. This led to an interpretation of the IR spectra of 1-butene on NaHY zeolites in terms of the isomerization to the cis- and trans-2-butene, rather than oligomerization on NaY and oligomerization, isomerization, fragmentation, or further side reaction on NaHY, as suggested by Ceckiewicz et al. The temperature-programed desorption measurements at temperatures up to 700/sup 0/K used by Ceckiewicz to analyze IR spectra taken at room temperature seem to be unsuitable for this purpose since subsequent reactions at higher temperatures cannot be ruled out.

The application of the HyPer fluorescent sensor in the real-time detection of H2O2 in Babesia bovis merozoites in vitro.

In recent years, genetically encoded fluorescent probes have allowed a dramatic advancement in time-lapse imaging, enabling this imaging modality to be used to investigate intracellular events in several apicomplexan parasite species. In this study, we constructed a plasmid vector to stably express a genetically encoded H 2 O 2 sensor probe called HyPer in Babesia bovis. The HyPer-transfected parasite population was successfully developed and subjected to a time-lapse imaging analysis under in vitro culture conditions. HyPer was capable of sensing an increasing H 2 O 2 concentration in the parasite cells which was induced by the administration of paraquat as a superoxide donor. HyPer fluorescence co-staining with MitoTracker Red indicated the mitochondria as the major source of reactive oxygen species (ROS) in parasite cells. The fluctuating ROS dynamics in the parasite gliding toward, attaching to, and invading the target red blood cell was visualized and monitored in real time with the HyPer expressing parasite population. This is the first report to describe the application of the HyPer probe in an imaging analysis involving Babesia parasites. Hyper-expressing parasites can be widely utilized in studies to investigate the mechanisms of emergence and the reduction of oxidative stress, as well as the signal transduction in the parasite cells during host invasion and intercellular development.

2017-05-01

Prolyl peptidases of the MEROPS S28 family are of particular interest because they are key enzymes in the digestion of proline-rich peptides. A BLAST analysis of the Aspergillus oryzae genome revealed sequences coding for four proteases of the S28 family. Three of these proteases, AoS28A, AoS28B, and AoS28C, were previously characterized as acidic prolyl endopeptidases. The fourth protease, AoS28D, showed high sequence divergence with other S28 proteases and belongs to a phylogenetically distinct cluster together with orthologous proteases from other Aspergillus species. The objective of the present paper was to characterize AoS28D protease in terms of substrate specificity and activity. AoS28D produced by gene overexpression in A. oryzae and in Pichia pastoris was a 70-kDa glycoprotein with a 10-kDa sugar moiety. In contrast with other S28 proteases, AoS28D did not hydrolyze internal Pro-Xaa bonds of several tested peptides. Similarly, to human lysosomal Pro-Xaa carboxypeptidase, AoS28D demonstrated selectivity for cleaving C-terminal Pro-Xaa bonds which are resistant to carboxypeptidases of the S10 family concomitantly secreted by A. oryzae. Therefore, AoS28D could act in synergy with these enzymes during sequential degradation of a peptide from its C-terminus.

Hybrid Correlation Energy (HyCE): An Approach Based on Separate Evaluations of Internal and External Components.

Science.gov (United States)

Ivanic, Joseph; Schmidt, Michael W

2018-06-04

A novel hybrid correlation energy (HyCE) approach is proposed that determines the total correlation energy via distinct computation of its internal and external components. This approach evolved from two related studies. First, rigorous assessment of the accuracies and size extensivities of a number of electron correlation methods, that include perturbation theory (PT2), coupled-cluster (CC), configuration interaction (CI), and coupled electron pair approximation (CEPA), shows that the CEPA(0) variant of the latter and triples-corrected CC methods consistently perform very similarly. These findings were obtained by comparison to near full CI results for four small molecules and by charting recovered correlation energies for six steadily growing chain systems. Second, by generating valence virtual orbitals (VVOs) and utilizing the CEPA(0) method, we were able to partition total correlation energies into internal (or nondynamic) and external (or dynamic) parts for the aforementioned six chain systems and a benchmark test bed of 36 molecules. When using triple-ζ basis sets it was found that per orbital internal correlation energies were appreciably larger than per orbital external energies and that the former showed far more chemical variation than the latter. Additionally, accumulations of external correlation energies were seen to proceed smoothly, and somewhat linearly, as the virtual space is gradually increased. Combination of these two studies led to development of the HyCE approach, whereby the internal and external correlation energies are determined separately by CEPA(0)/VVO and PT2/external calculations, respectively. When applied to the six chain systems and the 36-molecule benchmark test set it was found that HyCE energies followed closely those of triples-corrected CC and CEPA(0) while easily outperforming MP2 and CCSD. The success of the HyCE approach is more notable when considering that its cost is only slightly more than MP2 and significantly cheaper

The roles of phytochrome A (phyA), phytochrome B (phyB) and a putative blue-light (BL) photoreceptor (HY4) in the control of hypocotyl growth by natural radiation were investigated using phyA, phyB and hy4 mutants of Arabidopsis thaliana. Full sunlight inhibited hypocotyl growth to a larger extent in wild-type (WT) than in phyA, phyB and, particularly, hy4 seedlings. In WT seedlings, hypocotyl growth was promoted by selectively lowering BL irradiance, lowering red-light (R) plus far-red-light (FR) irradiance or lowering the R/FR ratio (which was achieved either by increasing FR or by reducing R). The effects of lowering BL were reduced in hy4 and exaggerated in phyA seedlings. The effects of lowering R+FR were reduced in phyA and exaggerated in hy4 seedlings. Neither phyB nor hy4 mutants responded to low R/FR ratios. Neighbouring plants reflecting FR without shading caused subtle reductions of the R/FR ratio. This signal promoted hypocotyl growth in WT but not in phyA, phyB or hy4 seedlings. Intermediate canopy shade produced similar effects in all genotypes. Under deep shade, de-etiolation was severely impaired in phyA seedlings, which died prematurely. Thus, the FR ‘high-irradiance reaction’ mediated by phyA could be important for seedling survival under dense canopies. (author)

Women with secondary recurrent pregnancy loss (RPL) after a boy have a reduced chance of live birth in the first pregnancy after referral if they carry HY-restricting HLA class II alleles, but long-term chance of live birth is unknown. Live birth was compared for 540 women with unexplained secondary RPL according to firstborn's sex and maternal carriage of HLA-DRB3*03:01, HLA-DQB1*05:01/02, HLA-DRB1*15, and HLA-DRB1*07. The groups were compared by Cox proportional hazard ratios. For women with at firstborn boy, maternal carriage of HY-restricting HLA class II alleles decreased chance of live birth: 0 vs 1: hazard ratio 0.75 (95% CI 0.55-1.02); 0 vs 2: HR 0.62 (0.40-0.94). Carriage of HY-restricting HLA class II alleles decreased chance of live birth only if the firstborn was a boy: boy vs girl: HR 0.72 (95% CI 0.55-0.98). Maternal carriage of HY-restricting HLA class II alleles decreases long-term chance of live birth in women with RPL after a boy. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To evaluate, in patients who underwent Fallopian-tube sterilization by hysteroscopic insertion of an Essure® device, the feasibility and accuracy of three-dimensional (3D) transvaginal sonography (TVS) to check the position of the device and 3D hysterosalpingo-foam sonography (3D-HyFoSy) using contrast-enhanced gel foam to assess consequent tubal occlusion. This was a prospective multicenter study conducted from June 2012 to July 2014 in four Italian centers, which included 50 women who underwent hysteroscopic Essure microinsert placement in a total of 95 Fallopian tubes. Placement of the microinserts was performed in an outpatient setting following standard procedure recommendations. All patients underwent transvaginal 3D-HyFoSy and hysterosalpingography (HSG) approximately 12-14 weeks after the procedure. The position of the devices was first checked on 3D-TVS and classified according to specific criteria (Positions A, B, C and D). Then, 3D-HyFoSy with ExEm® gel foam as the ultrasound contrast agent was performed to confirm tubal occlusion by the absence of contrast agent within the tubes and/or around the ovaries. To evaluate the feasibility of 3D-HyFoSy, consecutive volume acquisitions were performed while injecting the gel foam. After sonographic evaluation, women underwent HSG to assess the success of sterilization, as standard methodology. Side effects and pain evoked during and after 3D-HyFoSy and HSG were evaluated using a numeric pain rating scale. On 3D-TVS, 10 devices (10.5%) were in Position A, two (2.1%) in Position B, 59 (62.1%) in Position C and 24 (25.3%) in Position D. During 3D-HyFoSy, tubal occlusion was observed in 89 of 95 tubes (93.7%). In the six cases in which the passage of the contrast was observed, one device (16.7%) was in Position B, one device (16.7%) in Position D and four devices (66.7%) were found to lie in Position C. Tubal patency was confirmed at HSG with a concordance rate of 100%. The mean pain score associated with 3D-Hy

Identification of human semen is indispensable for the investigation of sexual assaults. Fluorescence staining methods using commercial kits, such as the series of SPERM HY-LITER™ kits, have been useful to detect human sperm via strong fluorescence. These kits have been examined from various forensic aspects. However, because of a lack of evaluation methods, these studies did not provide objective, or quantitative, descriptions of the results nor clear criteria for the decisions reached. In addition, the variety of validations was considerably limited. In this study, we conducted more advanced validations of SPERM HY-LITER™ Express using our established image analysis method. Use of this method enabled objective and specific identification of fluorescent sperm's spots and quantitative comparisons of the sperm detection performance under complex experimental conditions. For body fluid mixtures, we examined interference with the fluorescence staining from other body fluid components. Effects of sample decomposition were simulated in high humidity and high temperature conditions. Semen with quite low sperm concentrations, such as azoospermia and oligospermia samples, represented the most challenging cases in application of the kit. Finally, the tolerance of the kit against various acidic and basic environments was analyzed. The validations herein provide useful information for the practical applications of the SPERM HY-LITER™ Express kit, which were previously unobtainable. Moreover, the versatility of our image analysis method toward various complex cases was demonstrated.

The purpose of this study was to compare the cyclic fatigue resistances of Reciproc Blue (VDW, Munich, Germany), HyFlex EDM (Coltene/Whaledent, Altstätten, Switzerland), WaveOne Gold (Dentsply Maillefer, Ballaigues, Switzerland), and OneShape (Micro Mega, Besancon, France) single-file NiTi systems. Thirty Reciproc Blue R25 (25/.08), 30 HyFlex EDM (25/.∼), 30 WaveOne Gold Primary (25/.07), and 30 OneShape (25/.06) instruments were included in this study. All the instruments were rotated in artificial canals, which were made of stainless steel with an inner diameter of 1.5 mm, a 60° angle of curvature, and radii of curvatures of 5 mm until fracture occurred, and the time to fracture was recorded in seconds using a digital chronometer. The data were analyzed statistically using Kruskal-Wallis and post hoc Dunn tests via SPSS 21.0 software (SPSS Inc, Chicago, IL). The statistical significance level was set at 5%. The HyFlex EDM file (3456.33 ± 633.37) file had the statistically highest fatigue resistance, and the OneShape file (1221.63 ± 812.4) had the least fatigue resistance (P  .05) in the mean length of the fractured fragments of the files (P > .05). Within the limitations of the present in vitro study, it was found that cyclic fatigue resistance of HyFlex EDM files was higher than the cyclic fatigue resistances of OneShape, Reciproc Blue, and WaveOne Gold files.

Currently available methods for interrogating DNA-protein interactions at individual genomic loci have significant limitations, and make it difficult to work with unmodified cells or examine single-copy regions without specific antibodies. In this study, we describe a physiological application of the Hybridization Capture of Chromatin-Associated Proteins for Proteomics (HyCCAPP) methodology we have developed. Both novel and known locus-specific DNA-protein interactions were identified at the ENO2 and GAL1 promoter regions of Saccharomyces cerevisiae, and revealed subgroups of proteins present in significantly different levels at the loci in cells grown on glucose versus galactose as the carbon source. Results were validated using chromatin immunoprecipitation. Overall, our analysis demonstrates that HyCCAPP is an effective and flexible technology that does not require specific antibodies nor prior knowledge of locally occurring DNA-protein interactions and can now be used to identify changes in protein interactions at target regions in the genome in response to physiological challenges.

In the coming years there will be an unprecedented amount of SAR data available on a free and open basis to research and operational users around the globe. The Alaska Satellite Facility (ASF) DAAC hosts, through an international agreement, data from the Sentinel-1 spacecraft and will be hosting data from the upcoming NASA ISRO SAR (NISAR) mission. To more effectively manage and exploit these vast datasets, ASF DAAC has begun moving portions of the archive to the cloud and utilizing cloud services to provide higher-level processing on the data. The Hybrid Pluggable Processing Pipeline (HyP3) project is designed to support higher-level data processing in the cloud and extend the capabilities of researchers to larger scales. Built upon a set of core Amazon cloud services, the HyP3 system allows users to request data processing using a number of canned algorithms or their own algorithms once they have been uploaded to the cloud. The HyP3 system automatically accesses the ASF cloud-based archive through the DAAC RESTful application programming interface and processes the data on Amazon's elastic compute cluster (EC2). Final products are distributed through Amazon's simple storage service (S3) and are available for user download. This presentation will provide an overview of ASF DAAC's activities moving the Sentinel-1 archive into the cloud and developing the integrated HyP3 system, covering both the benefits and difficulties of working in the cloud. Additionally, we will focus on the utilization of HyP3 for higher-level processing of SAR data. Two example algorithms, for sea-ice tracking and change detection, will be discussed as well as the mechanism for integrating new algorithms into the pipeline for community use.

Obtaining a genetic profile from pieces of evidence collected at a crime scene is the primary objective of forensic laboratories. New procedures, methods, kits, software or equipment must be carefully evaluated and validated before its implementation. The constant development of new methodologies for DNA testing leads to a steady process of validation, which consists of demonstrating that the technology is robust, reproducible, and reliable throughout a defined range of conditions. The present work aims to internally validate two new retrotransposon-based kits (InnoQuant ® HY and InnoTyper ® 21), under the working conditions of the Laboratório de Polícia Científica da Polícia Judiciária (LPC-PJ). For the internal validation of InnoQuant ® HY and InnoTyper ® 21 sensitivity, repeatability, reproducibility, and mixture tests and a concordance study between these new kits and those currently in use at LPC-PJ (Quantifiler ® Duo and GlobalFiler™) were performed. The results obtained for sensitivity, repeatability, and reproducibility tests demonstrated that both InnoQuant ® HY and InnoTyper ® 21 are robust, reproducible, and reliable. The results of the concordance studies demonstrate that InnoQuant ® HY produced quantification results in nearly 29% more than Quantifiler ® Duo (indicating that this new kit is more effective in challenging samples), while the differences observed between InnoTyper ® 21 and GlobalFiler™ are not significant. Therefore, the utility of InnoTyper ® 21 has been proven, especially by the successful amplification of a greater number of complete genetic profiles (27 vs. 21). The results herein presented allowed the internal validation of both InnoQuant ® HY and InnoTyper ® 21, and their implementation in the LPC-PJ laboratory routine for the treatment of challenging samples.

Despite the extensive success with the introduction of M. bovis Bacille Calmette-Guérin (BCG), tuberculosis (TB) remains a major global epidemic infecting between 8 and 9 million people annually with an estimated 1.7 million deaths each year. However, because of its demonstrated effectiveness against some of the most severe forms of childhood TB, it is now realized that BCG vaccination of newborns is unlikely to be replaced. Therefore, BCG or an improved BCG will continue to be used as a prime TB vaccine and there is a need to develop effective boost vaccines that would enhance and prolong the protective immunity induced by BCG prime immunization. We report on a heterologous booster approach using two highly immunogenic TB antigens comprising Ag85B and TB10.4 (HyVac4) delivered as a fusion molecule and formulated in the proprietary adjuvant IC31. This vaccine was found to be immunogenic and demonstrated greater protection in the more stringent guinea pig model of pulmonary tuberculosis than BCG alone when used in a prime/boost regimen. Significant difference in lung involvement was observed for all animals in the HyVac4 boosted group compared to BCG alone regardless of time to death or sacrifice. A vaccine toxicology study of the HyVac4:IC31 regimen was performed and it was judged safe to advance the vaccine into clinical trials. Therefore, all non-clinical data supports the suitability of HyVac4 as a safe, immunogenic, and effective vaccination in a prime-boost regimen with BCG.

3D Risk Management for hydrogen installations (Hy3DRM)

This paper introduces the 3D Risk Management (3DRM) concept for hydrogen installations (Hy3DRM). The 3DRM framework entails an integrated solution for risk management that combines a detailed site-specific 3D geometry model for a system, a computational fluid dynamics (CFD) tool for simulating accident scenarios involving dispersion, fire and explosions, and a methodology for frequency analysis and quantitative risk assessment (QRA). In order to reduce calculation time, and to cover escalating accident scenarios such as structural collapse and projectiles, the CFD-based consequence analysis can be complemented with reduced order models or finite element analysis (FEA). The paper outlines the background for 3DRM and presents a proof-of-concept risk assessment for a hypothetical hydrogen filling station. This first prototype focuses on dispersion, fire and explosion scenarios resulting from loss of containment of gaseous hydrogen. The approach adopted here combines consequence assessments obtained with the CFD tool FLACS-Hydrogen from Gexcon, and event frequencies estimated with the Hydrogen Risk Assessment Models (HyRAM) tool from Sandia, to generate 3D risk contours for explosion pressure and radiation loads. For a given population density and set of harm criteria it is straightforward to extend the analysis to include personnel risk, as well as risk-based design such as detector optimization. The discussion outlines main challenges and inherent limitations of the 3DRM concept, as well as possibilities and prospects for future development. (author)

Introduction: M-Wire and reciprocating motion of WaveOne and controlled memory (CM) wire) of HyFlex were the recent innovations using thermal treatment. Therefore, a study was planned to evaluate the shaping ability of reciprocating motion of WaveOne and HyFlex using cone beam computed tomography (CBCT). Methodology: Forty-five freshly extracted mandibular teeth were selected and stored in saline until use. All teeth were scanned pre- and post-operatively using CBCT (Kodak 9000). All teeth were accessed and divided into three groups. (1) Group 1 (control n = 15): Instrumented with ProTaper. (2) Group 2 (n = 15): Instrumented with primary file (8%/25) WaveOne. (3) Group 3 (n = 15): Instrumented with (4%/25) HyFlex CM. Sections at 1, 3, and 5 mm were obtained from the pre- and post-operative scans. Measurement was done using CS3D software and Adobe Photoshop software. Apical transportation and degree of straightening were measured and statistically analyzed. Results: HyFlex showed lesser apical transportation when compared to other groups at 1 and 3 mm. WaveOne showed lesser degree of straightening when compared to other groups. Conclusion: This present study concluded that all systems could be employed in routine endodontics whereas HyFlex and WaveOne could be employed in severely curved canals. PMID:27994323

The accurate representation of aerosols in climate models requires direct ambient measurement of the size- and composition-dependent particle production fluxes. Here we present the design, testing, and analysis of data collected through the first instrument capable of measuring hygroscopicity-based, size-resolved particle fluxes using a continuous-flow Hygroscopicity-Resolved Relaxed Eddy Accumulation (Hy-Res REA) technique. The different components of the instrument were extensively tested inside the US Environmental Protection Agency's Aerosol Test Facility for sea-salt and ammoniums sulfate particle fluxes. The new REA system design does not require particle accumulation, therefore avoids the diffusional wall losses associated with long residence times of particles inside the air collectors of the traditional REA devices. The Hy-Res REA system used in this study includes a 3-D sonic anemometer, two fast-response solenoid valves, two Condensation Particle Counters (CPCs), a Scanning Mobility Particle Sizer (SMPS), and a Hygroscopicity Tandem Differential Mobility Analyzer (HTDMA). A linear relationship was found between the sea-salt particle fluxes measured by eddy covariance and REA techniques, with comparable theoretical (0.34) and measured (0.39) proportionality constants. The sea-salt particle detection limit of the Hy-Res REA flux system is estimated to be 6x105 m-2s-1. For the conditions of ammonium sulfate and sea-salt particles of comparable source strength and location, the continuous-flow Hy-Res REA instrument was able to achieve better than 90% accuracy of measuring the sea-salt particle fluxes. In principle, the instrument can be applied to measure fluxes of particles of variable size and distinct hygroscopic properties (i.e., mineral dust, black carbon, etc.).

Aerobic metabolism brings inexorably the production of reactive oxygen species (ROS), which are counterbalanced by intrinsic antioxidant defenses avoiding deleterious intracellular effects. Redox balance is the resultant of metabolic functioning under environmental inputs (i.e. diet, pollution) and the activity of intrinsic antioxidant machinery. Monitoring of intracellular hydrogen peroxide has been successfully achieved by redox biosensor advent; however, to track the intrinsic disulfide bond reduction capacity represents a fundamental piece to understand better how redox homeostasis is maintained in living cells. In the present work, we compared the informative value of steady-state measurements and the kinetics of HyPer, a H 2 O 2 -sensitive fluorescent biosensor, targeted at the cytosol, mitochondrion and endoplasmic reticulum. From this set of data, biosensor signal recovery from an oxidized state raised as a suitable parameter to discriminate reducing capacity of a close environment. Biosensor recovery was pH-independent, condition demonstrated by experiments on pH-clamped cells, and sensitive to pharmacological perturbations of enzymatic disulfide reduction. Also, ten human cell lines were characterized according their H 2 O 2 -pulse responses, including their capacity to reduce disulfide bonds evaluated in terms of their migratory capacity. Finally, cellular migration experiments were conducted to study whether migratory efficiency was associated with the disulfide reduction activity. The migration efficiency of each cell type correlates with the rate of signal recovery measured from the oxidized biosensor. In addition, HyPer-expressing cells treated with N-acetyl-cysteine had accelerated recovery rates and major migratory capacities, both reversible effects upon treatment removal. Our data demonstrate that the HyPer signal recovery offers a novel methodological tool to track the cellular impact of redox active biomolecules. Copyright © 2018 The Authors

To assess the deformation of HyFlex CM instruments (Coltene Whaledent) when used in two instrumentation sequences and to assess their shape recovery after heat sterilization. Simulated root canals with four different shapes were prepared with HyFlex CM instruments using a single-length technique (n = 40) or a crown down technique (n = 40). Pre-preparation, post-preparation and post-sterilization standardized images of each instrument were recorded. Assessment of instrument deformation and their subsequent shape recovery was carried out visually and by comparing the digitised images. Data analysis was carried out using chi-square tests. None of the 400 instruments fractured. Visual assessment of instruments post-preparation revealed that 30.5% had unwound and 0.5% had reverse winding. Following sterilization 8.5% remained unwound and 0.5% remained with reverse winding. When assessing instrument shape using digital images, 35.25% were unwound post-preparation, which reduced to 11% post-sterilization. Nine size 25, 0.08 instruments deformed, but none fully regained their original shape after sterilization; however, other sizes of deformed instruments did regain their shape (P recovery. © 2014 International Endodontic Journal.

Full Text Available O planejamento por meio de cenários completou 40 anos de existência. No período compreendido entre seu surgimento, em 1967, e o final da década de 70, observou-se um esforço analítico no sentido de aprimorar a técnica como ferramenta de apoio à decisão. Tal mobilização resultou em três linhas metodológicas distintas - as escolas de lógica intuitiva, de tendências probabilísticas e de análise prospectiva. Desde então, a preferência pela adoção da técnica dos cenários no planejamento não cresceu como se esperava. A limitação no seu uso é explicada pelo sucesso moderado que seus praticantes tiveram em balancear a tecnicalidade excessiva por um lado e a superficialidade relapsa por outro. Ademais, Millett (2003 destaca a reclamação da média gerência de que os cenários não tratam das situações competitivas e tampouco das decisões críticas que eles enfrentam em seus negócios. O autor sugere alguns desafios a serem enfrentados: (a resolver a confusão sobre a definição de cenário e as metodologias para a sua construção; (b esclarecer e ampliar as aplicações apropriadas aos cenários; e (c reduzir os recursos requeridos para executar o planejamento por cenários. O presente artigo tem por objetivo propor um procedimento para a construção de cenários que atenda a esses desafios. Por meio de uma abordagem exploratória, a metodologia proposta combina o julgamento subjetivo, obtido a partir da intuição dos especialistas, com métodos analíticos. O procedimento passo a passo foi aplicado ao longo da construção dos cenários alternativos para o consumo residencial de energia elétrica, no Estado do Paraná, até o ano 2015. As entrevistas estruturadas envolveram 14 especialistas selecionados por julgamento, e as informações secundárias foram coletadas de bases de dados socioeconômicos e do setor elétrico. Ao final, três cenários alternativos, com probabilidades subjetivas associadas, resultaram de

. Uma maneira de conseguir isso é pela melhoria dos testes de vigor. O teste de frio tem sido empregado em sementes de milho, no entanto, tem sido usado também para sementes de algodão (Gossypium spp., soja (Glycine Max, feijão ((Phaseolus vulgaris e ervilha (Pisum sativum. Este estudo foi conduzido com objetivo de ajustar o procedimento do teste para determinar o vigor de semente de soja. Foram utilizados seis lotes comerciais de semente de soja, cultivar BRS 133. O potencial fisiológico dos lotes foi avaliado usando-se os testes de germinação em rolo de papel toalha, tipo germitest, e em caixa com areia, de emergência de plântulas em campo, de tetrazólio, de envelhecimento acelerado e de condutividade elétrica. Determinou-se também o teor de água das sementes. Para composição dos procedimentos do teste de frio foi utilizada temperatura de 10ºC, tempo de permanência no frio por cinco dias, e quatro procedimentos: caixa com terra, rolo de papel com terra, rolo de papel sem terra e metodologia alternativa, rolo de papel sem terra sob água refrigerada. O delineamento experimental utilizado foi inteiramente casualizado com oito repetições e as médias foram comparadas pelo teste de Tukey (p = 0,05. Para verificar a dependência entre o método alternativo e os demais usou-se o coeficiente de correlação linear simples. Os procedimentos para condução do teste de frio apresentaram coeficientes de variação muito próximos (CV com destaque para a metodologia do rolo de papel com terra e procedimento alternativo, em média, com 94% e 93% de plântulas normais e CV de 3,2% e 3,6% respectivamente. O procedimento alternativo teve resultado satisfatório para estimar vigor da semente de soja, produzindo resultados consistentes em comparação ao procedimento tradicional.

The triglyceride-lowering effect of probiotics Lactobacillus plantarum KY1032 and Lactobacillus curvatus HY7601 were investigated. Male SD Wistar rats were randomly divided into three groups and fed high-fat diet (HFD), HFD and probiotics (5 X 10(9) CFU/day of L. plantarum KY1032 and 5 X 10(9) CFU/day of L. curvatus HY7601), or normal diet for 6 weeks. Probiotic treatment significantly lowered the elevated plasma triglyceride and increased plasma free fatty acid, glycerol, and plasma apolipoprotein A-V (ApoA-V) levels. The probiotic-treated group showed elevated hepatic mRNA expression of PPARα, bile acid receptor (FXR), and ApoA-V. These results demonstrate that L. plantarum KY1032 and L. curvatus HY7601 lower triglycerides in hypertriglyceridemic rats by upregulating ApoA-V, PPARα, and FXR.

Reactive oxygen species (ROS) production and breakdown have been studied in detail in plant-pathogenic fungi, including the rice blast fungus, Magnaporthe oryzae; however, the examination of the dynamic process of ROS production in real time has proven to be challenging. We resynthesized an existing ROS sensor, called HyPer, to exhibit optimized codon bias for fungi, specifically Neurospora crassa, and used a combination of microscopy and plate reader assays to determine whether this construct could detect changes in fungal ROS during the plant infection process. Using confocal microscopy, we were able to visualize fluctuating ROS levels during the formation of an appressorium on an artificial hydrophobic surface, as well as during infection on host leaves. Using the plate reader, we were able to ascertain measurements of hydrogen peroxide (H 2 O 2 ) levels in conidia as detected by the MoHyPer sensor. Overall, by the optimization of codon usage for N. crassa and related fungal genomes, the MoHyPer sensor can be used as a robust, dynamic and powerful tool to both monitor and quantify H 2 O 2 dynamics in real time during important stages of the plant infection process. © 2016 BSPP AND JOHN WILEY & SONS LTD.

2018-04-01

The purpose of this study was to evaluate the effect of a low amount of torsional preloading on the fatigue life and different degrees of cyclic fatigue on torsional failure of HyFlex EDM (EDM; Coltene-Whaledent, Allstetten, Switzerland) and HyFlex CM (CM; Coltene-Whaledent) instruments. EDM and CM files were used. The fatigue resistance was examined in a 5-mm radius and 60° single curve, and the mean number of cycles to failure (N f ) was recorded. The torque and rotation angles at failure of the instruments were measured according to ISO 3630-1. New files were precycled to 0%, 50%, and 75% of the N f , and torsional tests were then performed. Other new files were preloaded at 5%, 15%, 25%, and 50% of the mean rotation angles before the fatigue test. The fracture surfaces of the fragments were examined under a scanning electron microscope. The fatigue resistance of EDM instruments was higher than that of CM instruments (P EDM at 15% preloading (P EDM files even with 50% torsional preloading was significantly higher than unused CM files (P EDM files. Moderate precycling (50%) of EDM files increased their torsional resistance. The fractographic patterns corresponded to the pattern defined by the last stage test. A low amount (15%) of torsional preloading reduced the fatigue resistance of EDM files, whereas even extensive (75%) precyclic fatigue was not detrimental to their torsional resistance.

Macias, J.; Escalante, C.; Castro, M. J.

2017-12-01

Landslide tsunami hazard may be dominant along significant parts of the coastline around the world, in particular in the USA, as compared to hazards from other tsunamigenic sources. This fact motivated NTHMP about the need of benchmarking models for landslide generated tsunamis, following the same methodology already used for standard tsunami models when the source is seismic. To perform the above-mentioned validation process, a set of candidate benchmarks were proposed. These benchmarks are based on a subset of available laboratory data sets for solid slide experiments and deformable slide experiments, and include both submarine and subaerial slides. A benchmark based on a historic field event (Valdez, AK, 1964) close the list of proposed benchmarks. A total of 7 benchmarks. The Multilayer-HySEA model including non-hydrostatic effects has been used to perform all the benchmarking problems dealing with laboratory experiments proposed in the workshop that was organized at Texas A&M University - Galveston, on January 9-11, 2017 by NTHMP. The aim of this presentation is to show some of the latest numerical results obtained with the Multilayer-HySEA (non-hydrostatic) model in the framework of this validation effort.Acknowledgements.

HyLTL: a temporal logic for model checking hybrid systems

Directory of Open Access Journals (Sweden)

Davide Bresolin

2013-08-01

Full Text Available The model-checking problem for hybrid systems is a well known challenge in the scientific community. Most of the existing approaches and tools are limited to safety properties only, or operates by transforming the hybrid system to be verified into a discrete one, thus loosing information on the continuous dynamics of the system. In this paper we present a logic for specifying complex properties of hybrid systems called HyLTL, and we show how it is possible to solve the model checking problem by translating the formula into an equivalent hybrid automaton. In this way the problem is reduced to a reachability problem on hybrid automata that can be solved by using existing tools.

Molan, Yusuf Eshqi; Refahi, Davood; Tarashti, Ali Hoseinmardi

2014-04-01

This study applies matched filtering on the HyMap airborne hyperspectral data to obtain the distribution map of alteration minerals in the Maherabad area and uses virtual verification to verify the results. This paper also introduces "moving threshold" which tries to find an appropriate threshold value to convert gray scale images, produced by mapping methods, to target and background pixels. The Maherabad area, located in the eastern part of the Lut block, is a Cu-Au porphyry system in which quartz-sericite-pyrite, argillic and propylitic alteration are most common. Minimum noise fraction transform coupled with a pixel purity index was applied on the HyMap images to extract the endmembers of the alteration minerals, including kaolinite, montmorillonite, sericite (muscovite/illite), calcite, chlorite, epidote, and goethite. Since there was no access to any portable spectrometer and/or lab spectral measurements for the verification of the remote sensing imagery results, virtual verification achieved using the USGS spectral library and showed an agreement of 83.19%. The comparison between the results of the matched filtering and X-ray diffraction (XRD) analyses also showed an agreement of 56.13%.

Axens new HyC 10 technology optimized with FCC while processing bitumen from Western Canada

A low pressure mild hydroconversion (MHC) method was described. HyC Technology has been recently commercialized as a cost-effective way of integrating fluid catalytic cracking (FCC) pretreating at moderate pressures, while still meeting the current and projected future requirements for ultra low sulfur diesel fuel. MHC has a low-medium conversion with sufficient FCC feed throughput to maintain gasoline production along with optimized hydrogen consumption. The process was recently tested using Canadian bitumen at a United States PADD II refinery. Details of production processes, feed quality and cracking potential for Canadian bitumen were presented. Partially hydrotreated straight run diesel (HDT) techniques were also compared with the MHC method. It was noted that MHC converted diesel is more refractory than HDT converted diesel, and that HDT techniques remain more appropriate for a variety of feeds and in situations where there is a hydrogen deficiency. Plans are now in place to adjust MHC HyC technology towards current diesel specifications, as well as to ensure constant MHC conversion. Yields, diesel, and residue product quality data for the first commercial plant using the technology were presented, as well as feedstock design bases. refs., tabs., figs.

Full Text Available Micro-organismos estão presentes em toda a cadeia de processamento da carne, desde a matéria-prima até o produto final e compete aos programas de qualidade industrial verificar se existe contaminação na matéria-prima e nos produtos finais para, dessa forma, garantir um produto seguro ao consumidor. Para tanto, faz-se necessário utilizar metodologias alternativas à convencional na rotina diagnóstica dos laboratórios para obtenção de resultados confiáveis e em menor tempo possível. Com objetivo de verificar e comparar a correlação e o tempo de processamento, da metodologia convencional com as metodologias alternativas do sistema PetrifilmTM (3M e sistema TEMPO® (bioMeriéux, foi realizada contagem de micro-organismos mesófilos, de enterobactérias e de Escherichia coli. As amostras foram coletadas da superfície de carcaças suínas em um abatedouro com Inspeção Federal no Estado de Santa Catarina, Brasil. A contagem de micro-organismos mesófilos, de enterobactérias e Escherichia coli foi feita por meio de ensaios realizados com os métodos alternativos TEMPO®, Petrifilm™ e o método convencional de contagem de micro-organismos em placas. Após análise estatística, o coeficiente de correlação de Pearson (r demonstrou fortes correlações, acima de 0.70 entre as metodologias utilizadas para a contagem de enterobactérias e micro-organismos mesófilos, porém demonstrou moderada correlação, entre 0.30 a 0.70, para o diagnóstico de Escherichia coli. O uso dos métodos alternativos testados em substituição à metodologia convencional pode ser utilizado para diagnóstico de Escherichia coli, enterobactérias e micro-organismos mesófilos, por haver concordância entre os resultados encontrados, acrescido da rapidez dessas metodologias com benefício direto para a indústria de carne suína.Micro-organisms are present throughout the meat processing chain, from raw materials until finished product.

Full Text Available O cultivo in vitro de orquídeas possibilita elevadas porcentagens de germinação, quando comparadas a germinação natural dessas espécies, pois suas sementes possuem pouca ou nenhuma reserva nutritiva. Objetivou-se avaliar diferentes volumes de suspensão de sementes na propagação in vitro de Dendrobium nobile Lindl. var. nobilius e var. comet king em meio alternativo, sem subcultivos. Foram utilizadas 0,02 g de sementes de cada planta e desinfestadas em solução de hipoclorito de sódio a 0,8%, por 15 minutos, sendo diluídas em água estéril até completar 60 mL. Em ambiente asséptico, procedeu-se a semeadura in vitro. Foram pipetados 2, 3 ou 4 mL de cada suspensão de sementes em frascos de vidro de 600mL providos de tampa metálica e contendo 80 mL do meio de cultura alternativo. As culturas foram transferidas para sala de crescimento com temperatura e fotoperíodo controlados (25 ± 2 ºC; 16 horas permanecendo por seis meses nessas condições. O maior número de sementes potencialmente viáveis (426 mg-1 foi observado em D. nobile var. nobilius, enquanto D. nobile var. comet king apresentou 164 mg-1 sementes potencialmente viáveis. A variedade nobilius apresentou maiores resultados no número de plantas total e de plantas vivas, número de folhas, número e diâmetro de pseudobulbos e comprimento da maior raiz, característica dessa variedade, que é mais vigorosa. A inoculação de 2mL foi mais eficiente para a micropropagação das duas plantas, havendo menos concorrência entre as plântulas no frasco.

Full Text Available http://dx.doi.org/10.1590/S0104-026X2006000200006 A informação genética e as tecnologias são cada vez mais importantes no cuidado em saúde, não somente nos países desenvolvidos, mas no mundo todo. Vários fatores globais prometem aumentar a futura demanda para pesquisa e serviços de saúde em genética moralmente conscientes. Embora os enfermeiros sejam o maior grupo profissional, prestando cuidado de saúde no mundo todo, eles não tomaram a liderança rumo a esse desafio. Insights, a partir da análise feminista, ajudam a esclarecer algumas das relações sociais e dos obstáculos culturais que têm impedido a integração da tecnologia genética na área da enfermagem. Um modelo alternativo é sugerido – o modelo transdisciplinar –, o qual foi desenvolvido inicialmente por uma enfermeira e introduzido, na década de 1970, na prestação do cuidado em saúde e no serviço social para crianças com déficit de desenvolvimento. Esse modelo holístico permite que todo profissional de saúde tenha a mesma voz ao determinar como o cuidado de saúde em genética será globalizado.

Genetically encoded, fluorescent biosensors have been developed to probe the activities of various signaling molecules inside cells ranging from changes in intracellular ion concentrations to dynamics of lipid second messengers. HyPer is a member of this class of biosensors and is the first to dynamically respond to hydrogen peroxide (H2O2), a reactive oxygen species that functions as a signaling molecule. However, detailed characterization of HyPer's signal is not currently available within the context of bacteria exposed to external oxidative stress, which occurs in the immunological response of higher organisms against invasive pathogenic bacteria. Here, we performed this characterization, specifically in Escherichia coli exposed to external H2O2. We found that the temporal behavior of the signal does not correspond exactly to peroxide concentration in the system as a function of time and expression of the sensor decreases the peroxide scavenging activity of the cell. We also determined the effects of cell number, both before and after normalization of externally added H2O2 to the number of cells. Finally, we report quantitative characteristics of HyPer's signal in this context, including the dynamic range of the signal, the signal-to-noise ratio, and the half saturation constant. These parameters show statistically meaningful differences in signal between two commonly used strains of E. coli, demonstrating how signal can vary with strain. Taken together, our results establish a systematic, quantitative framework for researchers seeking to better understand the role of H2O2 in the immunological response against bacteria, and for understanding potential differences in the details of HyPer's quantitative performance across studies.

The GPU-based Tsunami-HySEA model (Macias, J. et al., Pure and Applied Geophysics, 1-37, 2017, Lynett, P. et al., Ocean modeling, 114, 2017) is used to test four tsunami events: the January, 13, 2007 earthquake in Kuril islands (Mw 8.1), the September, 29, 2009 earthquake in Samoa (Mw 8.3), the February, 27, 2010 earthquake in Chile (Mw 9.8) and the March, 11, 2011 earthquake in Tohoku (Mw 9.0). Initial conditions have been provided by NOAA Center for Tsunami Research (NCTR) obtained from DART inversion results. All simulations have been performed using a global 4 arc-min grid of the Ocean Pacific and three nested-meshes levels around the selected locations. Wave amplitudes time series have been computed at selected tide gauges located at each location and maximum amplitudes compared with both MOST model results and observations where they are available. In addition, inundation also has been computed at selected U.S. locations for the 2011 Tohoku and 2009 Samoa events under the assumption of a steady mean high water level. Finally, computational time is also evaluated in order to study the operational capabilities of Tsunami-HySEA for these kind of events.

SHB1/HY1 Alleviates Excess Boron Stress by Increasing BOR4 Expression Level and Maintaining Boron Homeostasis in Arabidopsis Roots

Directory of Open Access Journals (Sweden)

Full Text Available Boron is an essential mineral nutrient for higher plant growth and development. However, excessive amounts of boron can be toxic. Here, we report on the characterization of an Arabidopsis mutant, shb1 (sensitive to high-level of boron 1, which exhibits hypersensitivity to excessive boron in roots. Positional cloning demonstrated that the shb1 mutant bears a point mutation in a gene encoding a heme oxygenase 1 (HO1 corresponding to the HY1 gene involved in photomorphogenesis. The transcription level of the SHB1/HY1 gene in roots is up-regulated under excessive boron stimulation. Either overexpressing SHB1/HY1 or applying the HO1 inducer hematin reduces boron accumulation in roots and confers high boron tolerance. Furthermore, carbon monoxide and bilirubin, catalytic products of HO1, partially rescue the boron toxicity-induced inhibition of primary root growth in shb1. Additionally, the mRNA level of BOR4, a boron efflux transporter, is reduced in shb1 roots with high levels of boron supplementation, and hematin cannot relieve the boron toxicity-induced root inhibition in bor4 mutants. Taken together, our study reveals that HO1 acts via its catalytic by-products to promote tolerance of excessive boron by up-regulating the transcription of the BOR4 gene and therefore promoting the exclusion of excessive boron in root cells.

VHTR-based Nuclear Hydrogen Plant Analysis for Hydrogen Production with SI, HyS, and HTSE Facilities

2016-01-01

In this paper, analyses of material and heat balances on the SI, HyS, and HTSE processes coupled to a Very High Temperature gas-cooled Reactor (VHTR) were performed. The hydrogen production efficiency including the thermal to electric energy ratio demanded from each process is found and the normalized evaluation results obtained from three processes are compared to each other. The currently technological issues to maintain the long term continuous operation of each process will be discussed at the conference site. VHTR-based nuclear hydrogen plant analysis for hydrogen production with SI, HyS, and HTSE facilities has been carried out to determine the thermal efficiency. It is evident that the thermal to electrical energy ratio demanded from each hydrogen production process is an important parameter to select the adequate process for hydrogen production. To improve the hydrogen production efficiency in the SI process coupled to the VHTR without electrical power generation, the demand of electrical energy in the SI process should be minimized by eliminating an electrodialysis step to break through the azeotrope of the HI/I_2/H_2O ternary aqueous solution

Repression of MYBL2 by Both microRNA858a and HY5 Leads to the Activation of Anthocyanin Biosynthetic Pathway in Arabidopsis.

Science.gov (United States)

Wang, Yulong; Wang, Yiqing; Song, Zhaoqing; Zhang, Huiyong

2016-10-10

Extensive studies in various plants show that the anthocyanin biosynthetic process is affected by environmental factors and regulated by many transcription factors through sophisticated regulatory networks. However, it remains largely unclear about the roles of microRNA in this process. Here, we demonstrate that miR858a is a positive regulator of anthocyanin biosynthesis in Arabidopsis seedlings. Overexpression of miR858a enhances the accumulation of anthocyanins, whereas the reduced miR858a activity results in low levels of anthocyanins in STTM858 transgenic plants. We found that miR858a inhibits the expression of MYBL2, a key negative regulator of anthocyanin biosynthesis, by translational repression. In addition, ELONGATED HYPOCOTYL 5 (HY5) was shown to directly bind the MYBL2 promoter and represses its expression via specific histone modifications. Interestingly, we found that miR858a exhibits light-responsive expression in an HY5-dependent manner. Together, these results delineate the HY5-MIR858a-MYBL2 loop as a cellular mechanism for modulating anthocyanin biosynthesis, suggesting that integration of transcriptional and posttranscriptional regulation is critical for governing proper anthocyanin accumulation in response to light and other environmental factors.

Full Text Available O tambaqui é a principal espécie de peixe cultivado na Amazônia Ocidental. Porém durante o processo produtivo, práticas de manejo são necessárias para o monitoramento do crescimento e estado geral da sanidade dos animais. Para isso os animais devem ser anestesiados para maior segurança no trabalho. O eugenol, componente majoritário do óleo de cravo, tem sido bastante utilizado como anestésico alternativo para peixes por ser um produto natural e de baixo custo. Entretanto, estudos tratando de respostas metabólicas em peixes tropicais expostos a diferentes anestésicos são ainda necessários. Dentro desse intuito, o presente trabalho avaliou respostas metabólicas, detectadas por meio de alterações de parâmetros sanguíneos e plasmáticos do tambaqui, exposto ao eugenol em banhos anestésicos simulados. Respostas típicas ao estresse foram detectadas devido ao manuseio imposto aos peixes durante a realização dos banhos anestésicos. O eugenol não reduziu totalmente essas reações ao estresse. Por outro lado, esse anestésico não provocou estresse adicional em exposições curtas de 15 min em concentrações próximas a 20 mg L-1.Tambaqui is the main farmed fish in the Western Amazon. However, in handling this fish has to be anesthetized for safety purposes, usually when evaluating growth and health conditions. Eugenol, the main component of clove oil, has been reported as an alternative fish anesthetic, because it is an inexpensive natural product. However, continued studies are necessary about the metabolic responses of tropical fish to anesthetics. The present work evaluated metabolic responses of tambaqui to eugenol in simulated anesthetic baths, measuring blood and plasma parameters. Typical metabolic stress responses to handling were detected, but they were not totally reduced by eugenol. On the other hand, the anesthetic dissolved in water did not provoke any extra charge of stress during short-term exposures in

The Mediterranean area concentrates the major natural risks related to the water cycle, including heavy precipitation and flash-flooding during the fall season. The capability to predict such high-impact events remains weak because of the contribution of very fine-scale processes and their non-linear interactions with the larger scale processes. These societal and science issues motivate the HyMeX (Hydrological cycle in the Mediterranean Experiment, http://www.hymex.org/) experimental programme. HyMeX aims at a better quantification and understanding of the water cycle in the Mediterranean with emphasis on intense events. The observation strategy of HyMEX is organized in a long-term (4 years) Enhanced Observation Periods (EOP) and short-term (2 months) Special Observation Periods (SOP). HyMEX has identified 3 main Mediterranean target areas: North-West (NW), Adriatic (A) and South-East (SE). Within each target area several hydrometeorological sites for heavy rainfall and flash flooding have been set up. The hydrometeorological site in Central Italy (CI) is interested by both western and eastern fronts coming from the Atlantic Ocean and Siberia, respectively. Orographic precipitations play an important role due to the central Apennine range, which reaches nearly 3000 m (Gran Sasso peak). Moreover, convective systems commonly develop in CI during late summer and beginning of autumn, often causing localized hailstorms with cluster organized cells. Western fronts may heavily hit the Tiber basin crossing large urban areas (Rome), whereas eastern fronts can cause flash floods along the Adriatic coastline. Two major basins are involved within CI region: Tiber basin (1000 km long) and its tributary Aniene and the Aterno-Pescara basin (300 km long). The first HyMeX SOP1.1 was carried out from Sept. till Nov. 2012 in the NW target area. The Italian SOP1.1 was coordinated by the Centre of Excellence CETEMPS, University of L'Aquila, a city located in the CI heart. The CI area

The Very High Temperature Gas-Cooled Reactor (VHTR) coupled to the High Temperature Steam Electrolysis (HTSE) process is one of two reference integrated systems being investigated by the U.S. Department of Energy and Idaho National Laboratory for the production of hydrogen. In this concept the VHTR outlet temperature of 900 °C provides thermal energy and high efficiency electricity for the electrolysis of steam in the HTSE process. In the second reference system the Sulfur Iodine (SI) process is coupled to the VHTR to produce hydrogen thermochemically. In the HyPEP project we are investigating and characterizing these two reference systems with respect to production, operability, and safety performance criteria. Under production, plant configuration and working fluids are being studied for their effect on efficiency. Under operability, control strategies are being developed with the goal of maintaining equipment within operating limits while meeting changes in demand. Safety studies are to investigate plant response for equipment failures. Specific objectives in FY07 were (1) to develop HyPEP Beta and verification and validation (V&V) plan, (2) to perform steady state system integration, (3) to perform parametric studies with various working fluids and power conversion unit (PCU) configurations, (4) the study of design options such as pressure, temperature, etc. (5) to develop a control strategy and (6) to perform transient analyses for plant upsets, control strategy, etc for hydrogen plant with PCU. This report describes the progress made in FY07 in each of the above areas. (1) The HyPEP code numeric scheme and Graphic User Interface have been tested and refined since the release of the alpha version a year ago. (2) The optimal size and design condition for the intermediate heat exchanger, one of the most important components for integration of the VHTR and HTSE plants, was estimated. (3) Efficiency calculations were performed for a variety of working fluids for

Surface mineral maps of Afghanistan derived from HyMap imaging spectrometer data, version 2

Kokaly, Raymond F.; King, Trude V.V.; Hoefen, Todd M.

2013-01-01

This report presents a new version of surface mineral maps derived from HyMap imaging spectrometer data collected over Afghanistan in the fall of 2007. This report also describes the processing steps applied to the imaging spectrometer data. The 218 individual flight lines composing the Afghanistan dataset, covering more than 438,000 square kilometers, were georeferenced to a mosaic of orthorectified Landsat images. The HyMap data were converted from radiance to reflectance using a radiative transfer program in combination with ground-calibration sites and a network of cross-cutting calibration flight lines. The U.S. Geological Survey Material Identification and Characterization Algorithm (MICA) was used to generate two thematic maps of surface minerals: a map of iron-bearing minerals and other materials, which have their primary absorption features at the shorter wavelengths of the reflected solar wavelength range, and a map of carbonates, phyllosilicates, sulfates, altered minerals, and other materials, which have their primary absorption features at the longer wavelengths of the reflected solar wavelength range. In contrast to the original version, version 2 of these maps is provided at full resolution of 23-meter pixel size. The thematic maps, MICA summary images, and the material fit and depth images are distributed in digital files linked to this report, in a format readable by remote sensing software and Geographic Information Systems (GIS). The digital files can be downloaded from http://pubs.usgs.gov/ds/787/downloads/.

The objectives of this study were to evaluate the effects of feeding 5 different energy and nutrient dense diets to Hy-Line W-36 hens on long-term performance and economics. A total of 480 19 wk old Hy-Line W-36 Single Comb White Leghorn hens were weighed and randomly allocated to 6 replicate groups of 16 hens each (2 adjacent cages containing 8 hens per cage, 60.9×58.4 cm) per dietary treatment in a randomized complete block design. The hens were fed 5 treatment diets formulated to contain 85, 90, 95, 100, and 105% of the energy and nutrient recommendations stated in the 2009 Hy-Line Variety W-36 Commercial Management Guide. Production performance was measured for 52 wk from 19 to 70 wk age. Over the course of the trial, a significant increasing linear response to increasing energy and nutrient density was seen for hen-day egg production, egg weight, egg mass, feed efficiency, energy intake, and body weight (BW). Feed intake showed no significant linear level response to increasing energy and nutrient density except during the early production cycle. No consistent responses were noted for egg quality, percent yolk, and percent egg solids throughout the study. Significant linear responses due to energy and nutrient density were seen for egg income, feed cost, and income minus feed cost. In general, as energy and nutrient density increased, egg income and feed cost per hen increased, but income minus feed cost decreased. Overall, these results indicate that feeding Hy-Line W-36 hens increasing energy and nutrient-dense diets will increase egg production, egg weight, egg mass, feed efficiency, energy intake, BW, egg income, and feed cost, but decrease egg income minus feed cost. However, these benefits do not take effect in early production and seem to be most effective in later stages of the production cycle, perhaps "priming" the birds for better egg-production persistency with age. © 2015 Poultry Science Association Inc.

The French collaborative Project known as HyBou explores hydrogen storage as a key enabling technology for the extensive use of hydrogen as an energy carrier. HyBou aims to develop robust, safe and efficient compressed gaseous hydrogen (CGH2) storage systems and validate innovative materials and processes suitable for storage vessel manufacturing with improved performance at low cost. The development of a new generation of type-4 70 MPa vessel was described along with a newly developed liner based on polyurethane materials. The new liner presents increased thermal stability, hydrogen barrier properties and cost effectiveness. The project also aims to evaluate the potential of new high resistance fibers and develop an improved thermosetting resin for composite winding with enhanced mechanical resistance and durability. A specific apparatus was therefore designed to characterize and evaluate coupled thermal and mechanical fatigue resistance in representative conditions.

Full Text Available Nowadays, Physical Web together with the increase in the use of mobile devices, Global Positioning System (GPS, and Social Networking Sites (SNS have caused users to share enriched information on the Web such as their tourist experiences. Therefore, an area that has been significantly improved by using the contextual information provided by these technologies is tourism. In this way, the main goals of this work are to propose and develop an algorithm focused on the recommendation of Smart Point of Interaction (Smart POI for a specific user according to his/her preferences and the Smart POIs’ context. Hence, a novel Hybrid Recommendation Algorithm (HyRA is presented by incorporating an aggregation operator into the user-based Collaborative Filtering (CF algorithm as well as including the Smart POIs’ categories and geographical information. For the experimental phase, two real-world datasets have been collected and preprocessed. In addition, one Smart POIs’ categories dataset was built. As a result, a dataset composed of 16 Smart POIs, another constituted by the explicit preferences of 200 respondents, and the last dataset integrated by 13 Smart POIs’ categories are provided. The experimental results show that the recommendations suggested by HyRA are promising.

Hybridization Capture Using RAD Probes (hyRAD, a New Tool for Performing Genomic Analyses on Collection Specimens.

Directory of Open Access Journals (Sweden)

Tomasz Suchan

Full Text Available In the recent years, many protocols aimed at reproducibly sequencing reduced-genome subsets in non-model organisms have been published. Among them, RAD-sequencing is one of the most widely used. It relies on digesting DNA with specific restriction enzymes and performing size selection on the resulting fragments. Despite its acknowledged utility, this method is of limited use with degraded DNA samples, such as those isolated from museum specimens, as these samples are less likely to harbor fragments long enough to comprise two restriction sites making possible ligation of the adapter sequences (in the case of double-digest RAD or performing size selection of the resulting fragments (in the case of single-digest RAD. Here, we address these limitations by presenting a novel method called hybridization RAD (hyRAD. In this approach, biotinylated RAD fragments, covering a random fraction of the genome, are used as baits for capturing homologous fragments from genomic shotgun sequencing libraries. This simple and cost-effective approach allows sequencing of orthologous loci even from highly degraded DNA samples, opening new avenues of research in the field of museum genomics. Not relying on the restriction site presence, it improves among-sample loci coverage. In a trial study, hyRAD allowed us to obtain a large set of orthologous loci from fresh and museum samples from a non-model butterfly species, with a high proportion of single nucleotide polymorphisms present in all eight analyzed specimens, including 58-year-old museum samples. The utility of the method was further validated using 49 museum and fresh samples of a Palearctic grasshopper species for which the spatial genetic structure was previously assessed using mtDNA amplicons. The application of the method is eventually discussed in a wider context. As it does not rely on the restriction site presence, it is therefore not sensitive to among-sample loci polymorphisms in the restriction sites

Law, Nicholas M.; Ziegler, Carl; Tokovinin, Andrei

2016-08-01

We present plans for SRAO, the first Southern Robotic AO system. SRAO will use AO-assisted speckle imaging and Robo-AO-heritage high efficiency observing to confirm and characterize thousands of planet candidates produced by major new transit surveys like TESS, and is the first AO system to be capable of building a comprehensive several-thousand-target multiplicity survey at sub-AU scales across the main sequence. We will also describe results from Robo-AO, the first robotic LGS-AO system. Robo-AO has observed tens of thousands of Northern targets, often using a similar speckle or Lucky-Imaging assisted mode. SRAO will be a moderate-order natural-guide-star adaptive optics system which uses an innovative photoncounting wavefront sensor and EMCCD speckle-imaging camera to guide on faint stars with the 4.1m SOAR telescope. The system will produce diffraction-limited imaging in the NIR on targets as faint as mν = 16. In AO-assisted speckle imaging mode the system will attain the 30-mas visible diffraction limit on targets at least as faint as mν = 17. The system will be the first Southern hemisphere robotic adaptive optics system, with overheads an order of magnitude smaller than comparable systems. Using Robo-AO's proven robotic AO software, SRAO will be capable of observing overheads on sub-minute scales, allowing the observation of at least 200 targets per night. SRAO will attain three times the angular resolution of the Palomar Robo-AO system in the visible.

Lucas Lopes da Fonseca

Full Text Available ABSTRACT Objective: This study evaluated the reproducibility of the three main classifications of ankle fractures most commonly used in emergency clinical practice: Lauge-Hansen, Danis-Weber, and AO-OTA. The secondary objective was to assess whether the level of professional experience influenced the interobserver agreement for the classification of this pathology. Methods: The study included 83 digitized preoperative radiographic images of ankle fractures, in anteroposterior and lateral views, of different adults that had occurred between January and December 2013. For sample calculation, the estimated accuracy was approximately 15%, with a sampling error of 5% and a sampling power of 80%. The images were analyzed and classified by six different observers: two foot and ankle surgeons, two general orthopedic surgeons, and two-second-year residents in orthopedics and traumatology. The Kappa statistical method of multiple variances was used to assess the variations. Results: The Danis-Weber classification indicated that 40% of the agreements among all observers were good or excellent, whereas only 20% of good and excellent agreements were obtained using the AO and Lauge Hansen classifications. The Kappa index was 0.49 for the Danis-Weber classification, 0.32 for Lauge Hansen, and 0.38 for AO. Conclusion: The Hansen-Lauge classification presented the poorest interobserver agreement among the three systems. The AO classification demonstrated a moderate agreement and the Danis-Weber classification presented an excellent interobserver agreement index, regardless of professional experience.

2012-09-01

The German Aerospace Center's (DLR) Remote Sensing Technology Institute (IMF) operates a laboratory for the characterisation of imaging spectrometers. Originally designed as Calibration Home Base (CHB) for the imaging spectrometer APEX, the laboratory can be used to characterise nearly every airborne hyperspectral system. Characterisation methods will be demonstrated exemplarily with HySpex, an airborne imaging spectrometer system from Norsk Elektro Optikks A/S (NEO). Consisting of two separate devices (VNIR-1600 and SWIR-320me) the setup covers the spectral range from 400 nm to 2500 nm. Both airborne sensors have been characterised at NEO. This includes measurement of spectral and spatial resolution and misregistration, polarisation sensitivity, signal to noise ratios and the radiometric response. The same parameters have been examined at the CHB and were used to validate the NEO measurements. Additionally, the line spread functions (LSF) in across and along track direction and the spectral response functions (SRF) for certain detector pixels were measured. The high degree of lab automation allows the determination of the SRFs and LSFs for a large amount of sampling points. Despite this, the measurement of these functions for every detector element would be too time-consuming as typical detectors have 105 elements. But with enough sampling points it is possible to interpolate the attributes of the remaining pixels. The knowledge of these properties for every detector element allows the quantification of spectral and spatial misregistration (smile and keystone) and a better calibration of airborne data. Further laboratory measurements are used to validate the models for the spectral and spatial properties of the imaging spectrometers. Compared to the future German spaceborne hyperspectral Imager EnMAP, the HySpex sensors have the same or higher spectral and spatial resolution. Therefore, airborne data will be used to prepare for and validate the spaceborne system

Molecule dynamics (MD) simulation, a molecular-level method, was applied to predict the damping properties of AO-60/polyacrylate rubber (AO-60/ACM) composites before experimental measures were performed. MD simulation results revealed that two types of hydrogen bond, namely, type A (AO-60) -OH•••O=C- (ACM), type B (AO-60) - OH•••O=C- (AO-60) were formed. Then, the AO-60/ACM composites were fabricated and tested to verify the accuracy of the MD simulation through dynamic mechanical thermal analysis (DMTA). DMTA results showed that the introduction of AO-60 could remarkably improve the damping properties of the composites, including the increase of glass transition temperature (Tg) alongside with the loss factor (tan δ), also indicating the AO-60/ACM(98/100) had the best damping performance amongst the composites which verified by the experimental.

Full Text Available OBJETIVO: Existem poucos relatórios publicados com relação à eficácia do ibuprofeno via oral no tratamento da persistência do canal arterial (PCA em neonatos com extremo baixo peso ao nascer (EBPN. Comparamos o ibuprofeno via oral à indometacina intravenosa no que diz respeito à eficácia e segurança no tratamento de PCA em neonatos com peso inferior a 1.000 g ao nascer. MÉTODO: Este foi um estudo retrospectivo em um único centro. Coletamos dados de neonatos com EBPN que tiveram PCA ecocardiograficamente confirmada. Os neonatos foram tratados tanto com indometacina intravenosa quanto com ibuprofeno via oral. A taxa de fechamento do canal, a necessidade de tratamentos adicionais, os efeitos colaterais ou as complicações relacionadas ao medicamento e a mortalidade foram comparados entre os dois grupos de tratamento. RESULTADO: Examinamos 26 neonatos que receberam indometacina e 22 que receberam ibuprofeno. A taxa geral de fechamento do canal foi semelhante nos dois tratamentos: o fechamento do canal ocorreu em 23 dos 26 neonatos (88,5% no grupo indometacina, e em 18 dos 22 neonatos (81,8% no grupo ibuprofeno (p = 0,40. A taxa de ligadura cirúrgica (11,5% em comparação a 18,2%; p = 0,40 não diferiu de forma significativa entre os dois grupos de tratamento. Após o tratamento, não foi encontrada nenhuma diferença significativa nas concentrações de creatinina sérica entre os dois grupos. Não houve diferenças significativas com relação a efeitos colaterais ou complicações adicionais. CONCLUSÃO: Em neonatos com EBPN, o ibuprofeno via oral é tão eficaz quanto a indometacina intravenosa no tratamento da PCA. Não há diferenças entre os medicamentos no que diz respeito à segurança. O ibuprofeno via oral poderia ser usado como um agente alternativo no tratamento da PCA em neonatos com EBPN.

Millet, P.

2006-01-01

GenHyPEM (generateur d'hydrogene PEM) is an international research project related to the electrolytic production of hydrogen from water, using proton exchange membrane (PEM) - based electrochemical generators. The specificity of this project is that all basic research efforts are devoted to the optimization of already existing electrolysers of industrial size, in order to facilitate the introduction of this technology in the industry and to propose technological solutions for the industrial and domestic production of electrolytic hydrogen. GenHyPEM is a three years long research program financially supported by the European Commission, gathering partners from academic institutions and from the industry, in order to reach three main technological objectives aimed at improving the performances of current 1000 Nliter/hour H 2 industrial PEM water electrolysers: (i) Development of alternative low-cost membrane electrode assemblies and stack components with electrochemical performances similar to those of state-of-the-art systems. The objectives are the development of nano-scaled electrocatalytic structures for reducing the amount of noble metals; the synthesis and characterization of non-noble metal catalytic compounds provided by molecular chemistry and bio-mimetic approaches; the preparation of new composite membrane materials for high current density, high pressure and high temperature operation; the development and optimization of low-cost porous titanium sheets acting as current collectors in the electrolysis stack; (ii) Development of an optimized stack structure for high current density (1 A.cm-2) and high pressure (50 bars) operation for direct pressurized storage; (iii) Development of an automated and integrated electrolysis unit allowing gas production from intermittent renewable sources of energy such as photovoltaic-solar and wind. Current status of the project as well as perspectives are described in this paper. This project, coordinated by University of

Two experiments were conducted to examine the effects of feeding diets containing 69μg/ kg of vitamin D 3 or 25-hydroxycholecalciferol (Hy.D), 0.45% (P100) or 0.35% (P50) National Research Council's available phosphorus (P) requirement with or without natuphos (phytase) on broiler chickens performance. The results of the first experiment (balance study) indicated no significant effects (P>0.05) in body weight, feed consumption and feed conversion ratio of broilers at 21 days of age. Tibia bone ash percentage was not effected by the dietary treatments. Chicks fed the P100 diet had a significantly (P<0.05) higher apparent P retention than those fed the P50 diet. The pH of different segments of intestine was not affected by dietary treatments. The phytase activities in the duodenal contents and tissues were significantly (P<0.05) higher in the chicks receiving diets with Hy.D in the absence of phytase. There were no differences in the growth performance of broilers under commercial conditions due to sources of vitamin D in the diets at 39 days of age.(Author)

{gamma} alumina- and HY zeolite-supported molybdenum catalysts: characterisation of the oxidic and sulfided phases; Catalyseurs a base de molybdene supporte sur alumine {gamma} et zeolithe HY: caracterisation des phases oxydes et sulfures

Oxidic precursors of hydro-treatment catalysts (Co)Mo/alumina or zeolite were characterised by Raman spectroscopy, NMR and EXAFS at the Mo and Co K-edges. The formation of an Anderson-type alumino-molybdate compound upon impregnation of the support with an ammonium hepta-molybdate solution was confirmed for alumina, and also observed for the HY zeolitic support, with consumption of the amorphous alumina of the zeolite. In absence of the latter, ammonium hepta-molybdate precipitates. The species are conserved upon drying; upon calcination, the alumino-molybdate evolves into a surface aluminium molybdate type phase, whereas the hepta-molybdate transforms into MoO{sub 3}. The species formed upon impregnation are located in the inter-granular porosity whereas MoO{sub 3} vapor-condensation leads to formation of dimers located inside the zeolitic structure. The study of the cobalt-promoted precursors showed that the evolution of the molybdenum is the same in the case of co-impregnation preparation. Impregnation with cobalt-molybdate prevents the formation of the alumino-molybdate anion and thus enables the preservation of the Mo-Co interaction but, whatever the precursor, the leveling effect of the calcination-re-hydration steps was demonstrated. An EXAFS study at different sulfur coverages of the MoS{sub 2} platelets in the alumina-supported sulfided catalysts showed the limitations of EXAFS for size determination of MoS{sub 2} crystallites, a parameter that can be reached by AWAXS, which also conveys information about sheet-stacking. The EXAFS study of sulfided (Co)Mo/HY systems revealed incomplete sulfidation of the samples and the very high dispersion of the active phase. The absence of an observable Mo-Co interaction whatever the preparation of the promoted catalysts is consistent with the absence of promoting effect in toluene hydrogenation. (author)

To examine the cyclic fatigue resistances of R-Pilot, HyFlex EDM and PathFile NiTi glide path files in S-shaped artificial canals. Twenty R-Pilot (12.5/.04), 20 HyFlex EDM (10/.05) and 20 PathFile (19/.02) single-file glide path files were included. Sixty files (n: 20/each) were subjected to static cyclic fatigue testing using double-curved canals until fracture occurred (TF). The number of cycles to fracture (NCF) was calculated by multiplying the rpm value by the TF. The length of the fractured fragment (FL) was determined by a digital microcaliper. Six samples of fractured files (n: 2/each) were examined by SEM to determine the fracture mode. The NCF and the FL data were analysed using one-way anova, post hoc Tamhane and Kruskal-Wallis tests using SPPS 21 software. The significance level was set at 5%. In the double-curved canal, all the files fractured first in the apical curvature and then in the coronal curvature. The NCF values revealed that the R-Pilot had the greatest cyclic fatigue resistance, followed by the HyFlex EDM and PathFile in both the apical and coronal curvatures (P < 0.05). R-Pilot NiTi glide path files, used in a reciprocating motion, had the greatest cyclic fatigue resistance amongst the tested NiTi glide path files in an artificial S-shaped canal. © 2017 International Endodontic Journal.

Full Text Available Sailuotong (SLT is a standardised three-herb formulation consisting of Panax ginseng, Ginkgo biloba, and Crocus sativus designed for the management of vascular dementia. While the latest clinical trials have demonstrated beneficial effects of SLT in vascular dementia, the underlying cellular mechanisms have not been fully explored. The aim of this study was to assess the ability and mechanisms of SLT to act against hydrogen peroxide (H2O2-induced oxidative damage in cultured human vascular endothelial cells (EAhy926. SLT (1–50 µg/mL significantly suppressed the H2O2-induced cell death and abolished the H2O2-induced reactive oxygen species (ROS generation in a concentration-dependent manner. Similarly, H2O2 (0.5 mM; 24 h caused a ~2-fold increase in lactate dehydrogenase (LDH release from the EA.hy926 cells which were significantly suppressed by SLT (1–50 µg/mL in a concentration-dependent manner. Incubation of SLT (50 µg/mL increased superoxide dismutase (SOD activity and suppressed the H2O2-enhanced Bax/Bcl-2 ratio and cleaved caspase-3 expression. In conclusion, our results suggest that SLT protects EA.hy916 cells against H2O2-mediated injury via direct reduction of intracellular ROS generation and an increase in SOD activity. These protective effects are closely associated with the inhibition of the apoptotic death cascade via the suppression of caspase-3 activation and reduction of Bax/Bcl-2 ratio, thereby indicating a potential mechanism of action for the clinical effects observed.

Full Text Available Carbohydrate-containing molecules were located on the surface of Candida lipolytica by using ruthenium red in a cytochemical study. The yeast was grown in media containing Tween 80. The surfactant, at 1.0% and 0.5%, was added to the culture medium in different intervals of time, correspondent to the beginning of exponential growth phase, mid of logarithimic phase and beginning of stationary growth phase. Control cultures were grown in a medium containing glucose. The growth of the yeast in media containing glucose and Tween 80 induced changes in the pattern of distribution and location of acid polyssacharides in the cell wall of the microorganism. In adition, the pattern also changed according to Tween 80 concentration. The influence of Tween 80 on cellular carbohydrate expression is discussed.Moléculas contendo resíduos de açúcares foram localizadas sobre a superfície de Candida lipolytica utilizando-se o vermelho de rutênio como marcador citoquímico.

Variations in photosynthesis still cause substantial uncertainties in predicting photosynthetic CO2 uptake rates and monitoring plant stress. Changes in actual photosynthesis that are not related to greenness of vegetation are difficult to measure by reflectance based optical remote sensing techniques. Several activities are underway to evaluate the sun-induced fluorescence signal on the ground and on a coarse spatial scale using space-borne imaging spectrometers. Intermediate-scale observations using airborne-based imaging spectroscopy, which are critical to bridge the existing gap between small-scale field studies and global observations, are still insufficient. Here we present the first validated maps of sun-induced fluorescence in that critical, intermediate spatial resolution, employing the novel airborne imaging spectrometer HyPlant. HyPlant has an unprecedented spectral resolution, which allows for the first time quantifying sun-induced fluorescence fluxes in physical units according to the Fraunhofer Line Depth Principle that exploits solar and atmospheric absorption bands. Maps of sun-induced fluorescence show a large spatial variability between different vegetation types, which complement classical remote sensing approaches. Different crop types largely differ in emitting fluorescence that additionally changes within the seasonal cycle and thus may be related to the seasonal activation and deactivation of the photosynthetic machinery. We argue that sun-induced fluorescence emission is related to two processes: (i) the total absorbed radiation by photosynthetically active chlorophyll; and (ii) the functional status of actual photosynthesis and vegetation stress. © 2015 John Wiley & Sons Ltd.

Full Text Available Este trabalho estuda a microestrutura formada na zona termicamente afetada (ZTA e na zona fundida (ZF de uma junta soldada pelo processo TIG automático no passe de raiz, processo plasma nos passes de enchimento e soldagem SAW para os passes de acabamento em junta de topo com chanfro “V” simples, usando o aço inoxidável austenítico AISI 347. Foram estudadas as condições: como soldada; após tratamento térmico convencional de solubilização a 1060 °C e estabilização a 900 °C; e após tratamento térmico alternativo, onde a peça foi solubilizada a 1060 °C e mantida no forno que foi resfriado até 900 °C para a estabilização. Os resultados mostram que, na condição como soldado houve crescimento de grão na ZTA e a ZF apresentou 13% de ferrita com diferentes morfologias, tendo sido observada a precipitação de carbetos de Cr e de Nb. Após o tratamento térmico convencional de solubilização e estabilização, foi observada uma diminuição significativa do teor de ferrita na ZTA e na ZF, tendo sido observados carbetos de Nb e Cr, distribuídos de forma mais dispersa e com tamanhos menores, que contribuem para minimizar a possibilidade de ocorrer o fenômeno da sensitização. Após tratamento térmico alternativo de solubilização e estabilização, a microestrutura da ZTA e ZF foi similar à obtida no tratamento convencional, sendo que o teor de ferrita δ na ZF foi ainda mais reduzido, de 4,5%. Foi concluído que o tratamento térmico alternativo de solubilização e estabilização foi tão eficaz quanto o tratamento térmico convencional para a adequação da microestrutura da junta soldada, com uma significativa vantagem do tratamento térmico proposto em reduzir o tempo e o custo desta operação.

Full Text Available O uso desenfreado de agrotóxicos vem a ser um caso de saúde pública, pois prejudica a saúde do trabalhador do campo assim como do consumidor final desses produtos. O Sitophilus zeamais é uma praga de armazenamento que ataca o milho, e no combate a essa praga comumente é utilizado produtos tóxicos. Visando essa problemática, a busca por produtos alternativos vem a ser um campo de investigação promissor, pois esse método de controle não gera resíduos para o homem tão pouco ao meio ambiente. O extrato utilizado para avaliar o potencial de repelência foi o de Capsicum annuum L. popularmente conhecido como pimentão. Os testes foram realizados com a utilização de arenas, onde em cada arena foram liberados 30 adultos de S. zeamais, não sexados e após 24 horas, foram registrados o número de insetos em cada recipiente. Os grãos de milho foram tratados com volume de extrato correspondente a 1,0% da massa de grãos, nas concentrações 0,0 (álcool 70%; 25,0; 50,0; 75,0 e 100,0% (volume de extrato/volume álcool. O experimento foi organizado segundo o delineamento inteiramente casualizado e constou de cinco tratamentos e quatro repetições. As maiores repelências foram observadas nas concentrações de 25% e 100%, repelindo 72 e 70% dos insetos respectivamente. Sendo assim a utilização desse extrato pode ser empregado no tratamento de sementes armazenadas, evitando assim uma maior infestação desses insetos, preservando assim a integridade física e fisiológica das sementes.

The putative Notch ligand HyJagged is a transmembrane protein present in all cell types of adult Hydra and upregulated at the boundary between bud and parent

Full Text Available Abstract Background The Notch signalling pathway is conserved in pre-bilaterian animals. In the Cnidarian Hydra it is involved in interstitial stem cell differentiation and in boundary formation during budding. Experimental evidence suggests that in Hydra Notch is activated by presenilin through proteolytic cleavage at the S3 site as in all animals. However, the endogenous ligand for HvNotch has not been described yet. Results We have cloned a cDNA from Hydra, which encodes a bona-fide Notch ligand with a conserved domain structure similar to that of Jagged-like Notch ligands from other animals. Hyjagged mRNA is undetectable in adult Hydra by in situ hybridisation but is strongly upregulated and easily visible at the border between bud and parent shortly before bud detachment. In contrast, HyJagged protein is found in all cell types of an adult hydra, where it localises to membranes and endosomes. Co-localisation experiments showed that it is present in the same cells as HvNotch, however not always in the same membrane structures. Conclusions The putative Notch ligand HyJagged is conserved in Cnidarians. Together with HvNotch it may be involved in the formation of the parent-bud boundary in Hydra. Moreover, protein distribution of both, HvNotch receptor and HyJagged indicate a more widespread function for these two transmembrane proteins in the adult hydra, which may be regulated by additional factors, possibly involving endocytic pathways.

The reaction of 2,5-dimethylfuran and ethylene to produce p-xylene represents a potentially important route for the conversion of biomass to high-value organic chemicals. Current preparation methods suffer from low selectivity and produce a number of byproducts. Using modern separation and analytical techniques, the structures of many of the byproducts produced in this reaction when HY zeolite is employed as a catalyst have been identified. From these data, a detailed reaction network is proposed, demonstrating that hydrolysis and electrophilic alkylation reactions compete with the desired Diels–Alder/dehydration sequence. This information will allow the rational identification of more selective catalysts and more selective reaction conditions.

Peng, Yi; Zhang, Jie; Li, Dong

2018-03-01

A large wastewater treatment plant (WWTP) could not meet the new demand of urban environment and the need of reclaimed water in China, using a US treatment technology. Thus a multi AO reaction process (Anaerobic/oxic/anoxic/oxic/anoxic/oxic) WWTP with underground structure was proposed to carry out the upgrade project. Four main new technologies were applied: (1) multi AO reaction with step feed technology; (2) deodorization; (3) new energy-saving technology such as water resource heat pump and optical fiber lighting system; (4) dependable old WWTP’s water quality support measurement during new WWTP’s construction. After construction, upgrading WWTP had saved two thirds land occupation, increased 80% treatment capacity and improved effluent standard by more than two times. Moreover, it had become a benchmark of an ecological negative capital changing to a positive capital.

Full Text Available The effector repertoire of the olive pathogen P. savastanoi pv. savastanoi NCPPB 3335 includes two members of the HopAO effector family, one of the most diverse T3E families of the P. syringae complex. The study described here explores the phylogeny of these dissimilar members, HopAO1 and HopAO2, among the complex and reveals their activities as immune defense suppressors. Although HopAO1 is predominantly encoded by phylogroup 3 strains isolated from woody organs of woody hosts, both HopAO1 and HopAO2 are phylogenetically clustered according to the woody/herbaceous nature of their host of isolation, suggesting host specialization of the HopAO family across the P. syringae complex. HopAO1 and HopAO2 translocate into plant cells and show hrpL-dependent expression, which allows their classification as actively deployed type III effectors. Our data also show that HopAO1 and HopAO2 possess phosphatase activity, a hallmark of the members of this family. Both of them exert an inhibitory effect on early plant defense responses, such as ROS production and callose deposition, and are able to suppress ETI responses induced by the effectorless polymutant of P. syringae pv. tomato DC3000 (DC3000D28E in Nicotiana. Moreover, we demonstrate that a ΔhopAO1 mutant of P. savastanoi NCPBB 3335 exhibits a reduced fitness and virulence in olive plants, which supports the relevance of this effector during the interaction of this strain with its host plants. This work contributes to the field with the first report regarding functional analysis of HopAO homologs encoded by P. syringae or P. savastanoi strains isolated from woody hosts.

Storm scenarios have been established from these parameters and the chronology of the most impacting recent storm. Sea level rise has been integrated (20 cm for year 2030 and 60 cm for year 2100, and the coastal flooding has been simulated with a non-hydrostatic non-linear shallow-water model (SWASH. The calculations have been realized on high resolution DEM (1 to 5 m mesh size, integrating buildings and coastal protections. The approach has been validated by reproducing a recent flooding event. Obtained results show the importance of wave overtopping in current coastal flooding hazard in this area. Nevertheless, if Hyéres-les-Palmiers is currently little exposed to coastal flooding, these simulations highlight an increasing role of overflowing due to sea level rise, leading to significant flooding in 2100, even for quite frequent events.

Robo-AO is the first and only fully automated adaptive optics laser guide star AO instrument. It was developed as an instrument for 1-3m robotic telescopes, in order to take advantage of their availability to pursue large survey programs and target of opportunity observations that aren't possible with other AO systems. Robo-AO is currently the most efficient AO system in existence, and it can achieve an observation rate of 20+ science targets per hour. In more than three years of operations at Palomar Observatory, it has been quite successful, producing technology that is being adapted by other AO systems and robotic telescope projects, as well as several high impact scientific publications. Now, Robo-AO has been selected to take over operation of the Kitt Peak National Observatory 2.1m telescope. This will give Robo-AO KP the opportunity to pursue multiple science programs consisting of several thousand targets each during the three years it will be on the telescope. One-sixth of the observing time will be allocated to the US community through the NOAO TAC process. This presentation will discuss the process adapting Robo-AO to the KPNO 2.1m telescope, the plans for integration and initial operations, and the science operations and programs to be pursued.

Full Text Available Resumen: Los procedimientos de evaluación de los sistemas alternativos de acceso al ordenador son poco rigurosos, sistemáticos y formales. Este trabajo presenta una metodología para la valoración de la interacción usuario-ordenador, cuando los sistemas de eye-tracking son utilizados como herramienta de acceso alternativo al ordenador por personas con Parálisis Cerebral (PC. Para ello, proponemos tres métricas de evaluación: tasa de fallos de calibración, tasa de error en el clic y tiempo de clic. Validamos la metodología, comparando 3 (tres eye- trackers, con 9 (nueve participantes con PC con trastornos motores severos. Los resultados indican que la calibración es un proceso crítico en estos escenarios como refleja la alta tasa de fallos de calibración medida. Los participantes con PC también tienen una alta tasa de error del clic, lo que indica que el uso de eye-trackers para alcanzar un objeto en pantalla es un proceso complejo para estos niveles de discapacidad motriz. Los tiempos de clics son similares entre todos los eye-trackers y participantes. Este trabajo pretende establecer líneas metodológicas para la efectiva evaluación de estos dispositivos, que pueden llegar a ser una interesante alternativa de acceso al ordenador para esta población.

Full Text Available RESUMO: As cidades de porte médio no Brasil têm ocupado posição de destaque nos últimos anos. Porém, estas cidades têm seguido o mesmo caminho das cidades brasileiras mais populosas e negligenciado aspectos que garantam à manutenção das condições que favorecem investimentos públicos e principalmente privados. Em relação aos sistemas de transporte e logística, cada vez mais as cidades de porte médio têm se tornado dependente do uso do automóvel e evitado políticas de incentivo à mobilidade urbana sustentável. Desta forma, entender a percepção dos usuários dos sistemas de transporte urbano é fundamental para traçar medidas de incentivo para modos alternativos de viagens urbanas. O objetivo deste estudo é apresentar uma análise da percepção dos usuários quanto aos modos de deslocamento urbano, principalmente a bicicleta e medidas específicas de incentivo ao uso deste modo não motorizado. A pesquisa foi realizada por meio de entrevistas com um questionário impresso. As respostas possibilitaram obter a opinião sobre o uso da bicicleta como modo de transporte, caracterizar o perfil socioeconômico dos entrevistados e simular um cenário em relação ao uso da bicicleta. Para o caso específico deste estudo ficou evidente que os entrevistados são favoráveis ao uso da bicicleta e uma parcela está disposta a usar o ciclismo desde que sejam implantadas medidas de incentivo. ABSTRACT: The medium-sized cities in Brazil have occupied a prominent position in the last years. However, these cities have followed the same path of the most populous Brazilian cities and have neglected aspects that guarantee the maintenance of the conditions that favor public and private investments. Regarding transport and logistics systems, more and more medium-sized cities have become dependent on the use of the car and have avoided policies to encourage sustainable urban mobility.

The experiment was conducted with 160 Hy-Line W36 layer hens (47 weeks of age, kept in cages of 25 cm, distributed in a completely randomized design, with eight birds and four replications. The control diet was on a cornand soybean meal base and the other diets had 50 or 100% of substitution of corn by sorghum, low tannin. The paprika, when supplemented, was added in 500 g t-1 or 1,000 g t-1. to the ration of low or high sorghum levels, respectively. The substitution of the cornby sorghum did not affect the performance of laying hens, but decreased the yolk pigmentation. When the natural pigment was added, in both dosages, the yolk pigmentation was higher than that obtained from the control diet, but the level of 1,000 g t-1. reduced theperformance of layers.

Para isso, foram realizados dois experimentos: um utilizando herbicidas de manejo, com mecanismos de ação alternativos, comparando a eficácia destes com os inibidores da ACCase; e outro apenas com herbicidas inibidores da ACCase e aditivos misturados à calda. As sementes resistentes foram produzidas a partir de plantas comprovadamente resistentes; para comparação de resultados, foi utilizada uma população de capim-marmelada que nunca tinha sido pulverizada com inibidores da ACCase, portanto uma população suscetível. O experimento com os herbicidas de manejo foi realizado em condições de campo, porém as plantas ficaram em caixas com capacidade de 50 L, evitando-se a disseminação destas para áreas adjacentes. Concluiu-se que as plantas resistentes não apresentam resistência múltipla com herbicidas de manejo com mecanismos de ação alternativos, podendo os herbicidas glyphosate, paraquat, sulfosate, paraquat + diuron, MSMA e glufosinate ser utilizados no período entressafra das áreas com sistema de plantio direto, para manejo de populações resistentes de capim-marmelada aos herbicidas inibidores da ACCase. O experimento com aditivos foi realizado em casa de vegetação, com plantas em vasos individuais, utilizando sementes das populações suscetíveis e resistentes. Os herbicidas utilizados foram inibidores da ACCase, em cuja calda foram adicionados aditivos nitrogenados, do tipo uréia e sulfato de amônio, além de um tratamento sem aditivos. Concluiu-se que os aditivos não alteraram a eficácia dos herbicidas inibidores da ACCase nas plantas provenientes tanto da população suscetível quanto da resistente.The objective of this research was to

Para determinar a sensibilidade da flor ao etileno, hastes foram cortadas e colocadas em câmaras herméticas e em seguida tratadas por 24 horas com diferentes concentrações de etileno variando de 0,0; 0,1; 1,0; 10; 100 e 1000 µL L-1do ar no interior da câmara. A rosa teve a vida pós-colheita reduzida pelo etileno, quando exposta a concentração igual ou superior a 10 µL L-1 de etileno. As flores tratadas com no mínimo de 10 µL L-1de etileno desenvolveram necrose, murcha e abscisão prematura das pétalas ainda túrgidas. As concentrações de 0,1 e 1,0 µL L-1de etileno estimularam a abertura do botão floral durante o período de 24 horas de exposição ao etileno, sem no entanto, reduzir a vida pós-colheita. A rosa 'Osiana' pode ser classificada como uma cultivar sensível ao etileno e a concentração influência os processos estimulados.

The resulting NS 4 coordination geometry is closer to a square-pyramid than a trigonal bipyramid in the case of (I), but almost inter-mediate between the two extremes in (II). The mol-ecular packing features (hy-droxy)O-H⋯O(hy-droxy) hydrogen bonds, leading to supra-molecular chains with a zigzag arrangement along [10-1] (I) or a helical arrangement along [010] (II). In (I), π-π [inter-centroid distances = 3.4738 (10) and 3.4848 (10) Å] between coordinating and non-coordinating pyridine mol-ecules lead to stacks comprising alternating rings along the a axis. In (II), weaker π-π contacts occur between centrosymmetrically related pairs of coordinating pyridine mol-ecules [inter-centroid separation = 3.9815 (14) Å]. Further inter-actions, including C-H⋯π(chelate) inter-actions in (I), lead to a three-dimensional architecture in each case.

Full Text Available Dores lombares são alterações músculos-esqueléticas mais comuns nas sociedades industrializadas e acometem entre 70% a 80,5% da população em ambos os sexos. As algias são decorrentes ao esforço requerido para atividades do trabalho e da vida diária. Sendo evidenciadas como sinais clínicos, a imobilidade e a deformidade antálgica para as quais, qualquer tentativa de movimento ativo ou passivo irá produzir a dor. Observou-se que em exercícios orientados (alongamento, caminhar, natação entre outros há uma redução das dores lombares subagudas ou crônicas, além da melhora da disfunção física e psicológica e prevenção da recorrência. Outro item analisado é que o alongamento associado ao ultrassom proporciona uma redução rápida das algias. Logo, a lombalgia é uma das patologias mais estudadas na área médica em questão de estudo etiológica e sintomatologia clínica in vivo. Entretanto, esses estudos envolvem tratamentos conservadores, ou alternativos, invasivos com uso de medicamentosos. Isso, sendo pouco aproveitado no campo fisioterápico.

Jurisdicción y medios alternativos de resolución de conflictos: una opción para las cuestiones ambientales

Carlos Alberto Lunelli

2014-10-01

Full Text Available A medida que las sociedades se fueron tornando más complejas, comenzaron a surgir nuevas categorías de conflictos, como es el caso de los conflictos ambientales. Sin embargo, el sistema procesal vigente todavía se rige por un ordenamiento jurídico positivista, apegado fundamentalmente a las directrices enmarcadas en la ley, ya que en la actualidad se utiliza la misma estructura judicial para resolver todo tipo de apremios. Como resultado de ello, se observa una deficiencia, por parte del Estado, en tutelar los nuevos derechos que surgen en una sociedad en constante evolución. Dado este contexto, el presente trabajo plantea la necesidad de utilizar medios alternativos de resolución de controversias, tales como la mediación-conciliación como opciones viables para poner fin a los conflictos ambientales, y con ello obtener una solución mediante medidas específicas al caso concreto.

We present new on-sky results for the Subaru Coronagraphic Extreme Adaptive Optics imager (SCExAO) verifying and quantifying the contrast gain enabled by key components: the closed-loop coronagraphic low-order wavefront sensor (CLOWFS) and focal plane wavefront control ("speckle nulling"). SCExAO will soon be coupled with a high-order, Pyramid wavefront sensor which will yield greater than 90% Strehl ratio and enable 10(exp 6) -10(exp 7) contrast at small angular separations allowing us to image gas giant planets at solar system scales. Upcoming instruments like VAMPIRES, FIRST, and CHARIS will expand SCExAO's science capabilities.

2016-04-01

Changes in temporal and total water availability due to hydrologic and climate change requires an efficient use of resources through the selection of the best adaptation options. HyCAW provides a novel service to users willing or needing to adapt to hydrological change, by turning available scientific information into a user friendly online wizard that lets to: • Evaluate the monthly reduction of water availability induced by climate change; • Select the best adaptation options and visualize the benefits in terms of water balance and cost reduction; • Quantify potential of water saving by improving of water use efficiency. The tool entails knowledge of the intra-annual distribution of available surface and groundwater flows at a site under present and future (climate change) scenarios. This information is extracted from long term scenario simulation by E-HYPE (European hydrological predictions for the environment) model from Swedish Meteorological and Hydrological Institute, to quantify the expected evolution in water availability (e.g. percent reduction of soil infiltration and aquifer recharge; relative seasonal shift of runoff from summer to winter in mountain areas; etc.). Users are requested to provide in input their actual water supply on a monthly basis, both from surface and groundwater sources. Appropriate decision trees and an embedded precompiled database of Water saving technology for different sectors (household, agriculture, industrial, tourisms) lead them to interactively identify good practices for water saving/recycling/harvesting that they may implement in their specific context. Thanks to this service, users are not required to have a detailed understanding neither of data nor of hydrological processes, but may benefit of scientific analysis directly for practical adaptation in a simple and user friendly way, effectively improving their adaptation capacity. The tool is being developed under a collaborative FP7 funded project called SWITCH

Orogenias: das margens continentais ao interior remoto das placas, uma revisão no tema

Directory of Open Access Journals (Sweden)

Benjamim Bley de Brito Neves

2016-05-01

Full Text Available Esta síntese do conceito de orogenias abrange desde a Tectônica de Placas dos anos 1970, adendos e modelos "alternativos", que buscam explicar orogenias distantes das zonas de interação de placas. A análise crítica dos modelos originais resultou em adendos que incluem domínios proterozoicos e paleozoicos e observações sobre reologia e história termo-tectônica da litosfera. Os modelos alternativos explicam a orogênese por subdução local de litosfera continental, sem envolver litosfera oceânica. Nos anos 1990, houve notável avanço no estudo das causas da subsidência (tectônica formadora de bacias e estudos que contestam a rigidez das placas e propõem modelos de enfraquecimento devido à ação termal. Orogenias intracontinentais, entendidas como caso extremo da inversão de bacias, ocorrem em praticamente todos os continentes. Esforços gerados em zonas de interação de placas podem ser transmitidas continente adentro por milhares de quilômetros e gerar tectônica deformadora longe de suturas. Embora esteja ainda em estágio de fluxo, o conceito de orogenias intracontinentais ("telessuturais" vem se consolidando, embora não tenha sido incorporado a livros-texto. O histórico e o reexame do tema possibilitam classificar os orógenos segundo três variáveis principais: posição em relação às zonas de sutura, organização geométrico-geológica (em planta e nível de exumação.

Múltiplas modernidades ou variedade da modernidade?

Directory of Open Access Journals (Sweden)

Volker H. Schmidt

2007-06-01

Full Text Available O artigo apresenta uma avaliação crítica do conceito de "múltiplas modernidades" que ganhou terreno na Sociologia na década de 1990. Ele rejeita essa noção como tanto conceitualmente equivocada quanto empiricamente infundada e propõe um conceito alternativo - de "variedades da modernidade" -, que se acredita resolver mais facilmente as questões substantivas do conceito anterior, ao mesmo tempo em que permite que se fale de "modernidade" no singular. A principal fonte de inspiração para esse conceito alternativo são as variedades do paradigma capitalista que guia a literatura da Nova Economia Política; uma de suas vantagens em relação ao paradigma das múltiplas modernidades é o foco nas instituições, muito mais que nas vagas e pouco explicativas noções de "cultura" e "diferença cultural". Entretanto, a abordagem de variedades da modernidade que siga essa via tem que ser muito mais ampla e compreensiva e deve, portanto, ser mais difícil de desenvolver e de aplicar que o paradigma de variedades do capitalismo. Mas mesmo que em última instância ela prove-se impraticável, a mera consideração de seus pré-requisitos metodológicos ainda promete fornecer valiosas sugestões para os pesquisadores da modernidade.

A non-linear detection of phospho-histone H2AX in EA.hy926 endothelial cells following low-dose X-irradiation is modulated by reactive oxygen species

International Nuclear Information System (INIS)

Large, Martin; Reichert, Sebastian; Hehlgans, Stephanie; Fournier, Claudia; Rödel, Claus; Rödel, Franz

2014-01-01

A discontinuous dose response relationship is a major characteristic of the anti-inflammatory effects of low-dose X-irradiation therapy. Although recent data indicate an involvement of a variety of molecular mechanisms in these characteristics, the impact of reactive oxygen species (ROS) production to give rise or contribute to these phenomena in endothelial cells (EC) remains elusive. HUVEC derived immortalized EA.hy926 cells were stimulated by tumor necrosis factor-α (TNF-α, 20 ng/ml) 4 h before irradiation with doses ranging from 0.3 to 1 Gy. To analyse DNA repair capacity, phospho-histone H2AX foci were assayed at 1 h, 4 h and 24 h after irradiation. ROS production and superoxide dismutase (SOD) activity were analysed by fluorometric 2′,7′-dichlorodihydrofluorescein-diacetate (H2DCFDA) and colorimetric assays. A functional impact of ROS on γH2AX production was analysed by treatment with the scavenger N-acetyl-L-cysteine (NAC). Irrespective of stimulation by TNF-α, EA.hy926 cells revealed a linear dose response characteristic of γH2AX foci detection at 1 h and 4 h after irradiation. By contrast, we observed a discontinuity in residual γH2AX foci detection at 24 h after irradiation with locally elevated values following a 0.5 Gy exposure that was abolished by inhibition of ROS by NAC. Moreover, SOD protein expression was significantly decreased at doses of 0.5 Gy and 0.7 Gy concomitant with a reduced SOD activity. These data implicate a non-linear regulation of ROS production and SOD activity in EA.hy926 EC following irradiation with doses < 1 Gy that may contribute to a discontinuous dose-response relationship of residual γH2AX foci detection

The reaction of CoCl 2 ·6H 2 O, N , N -bis-(2-hy-droxy-eth-yl)glycine and tri-ethyl-amine (Et 3 N) in ethanol solution under solvothermal conditions produced crystals of [ N , N -bis-(2-hy-droxy-eth-yl)glycinato]chloridocobalt(II), [Co(C 6 H 12 NO 4 )Cl]. The Co II ion is coordinated in a slightly distorted trigonal-bipyramidal environment which is defined by three O atoms occupying the equatorial plane and the N and Cl atoms in the apical sites. In the crystal, two types of O-H⋯O hydrogen bonds connect the mol-ecules, forming a two-dimensional network parallel to (001). The mol-ecular structure of the title compound confirms the findings of FTIR, elemental analysis, ESI-MS analysis and TG analysis. By using the density functional theory (DFT) (B3LYP) method with 6-31G(d) basis set, the molecular structure has been calculated and optimized.

O direito fundamental ao conteúdo do próprio trabalho: uma reconstrução normativa do direito ao trabalho

Leonardo Vieira Wandelli

2016-12-01

Full Text Available Resumo: Pretende-se enfrentar a inefetividade do direito humano e fundamental ao trabalho a partir de um esforço de reconstrução normativa da sua fundamentação, apoiada em um duplo pilar teórico, nas teorias das necessidades e nas teorias do reconhecimento. Com isso, não somente se recupera a importância do vínculo entre trabalho e dignidade humana, como se explicitam aspectos essenciais da centralidade do trabalho para os sujeitos. A partir disso, o direito ao trabalho se desvela não apenas como necessidade radical, tendente à transformação da institucionalidade vigente, mas também como direito positivado em um amplo leque de normas internacionais e nacionais, que contempla diversas dimensões normativas atualmente exigíveis. Propõe-se que, no centro desse direito, está um direito fundamental ao conteúdo do próprio trabalho, que determina juridicamente as condições da atividade e da organização do trabalho. Recente estudo adotado pelo Alto Comissariado em Direitos Humanos da Organização das Nações Unidas (ONU sobre o direito ao trabalho reforça essa compreensão. Palavras-chave: Direitos humanos. Direitos fundamentais. Direito ao trabalho. Psicodinâmica do trabalho. Direito do trabalho.

Full Text Available OBJETIVO: São vários os fatores que contribuem para a má adesão ao tratamento de crianças e adolescentes com doenças reumáticas crônicas, gerando piora da qualidade de vida e do prognóstico. Nosso objetivo foi avaliar as taxas de adesão ao tratamento e identificar os fatores socioeconômicos e clínicos associados. MÉTODOS: Foram incluídos 99 pacientes com artrite idiopática juvenil, lúpus eritematoso sistêmico, dermatomiosite ou esclerodermia juvenil. Todos os pacientes eram acompanhados no ambulatório de reumatologia pediátrica por um período mínimo de 6 meses. Para avaliação da adesão, foi aplicado aos cuidadores um questionário composto por três blocos: 1 dados demográficos, clínicos e laboratoriais; 2 adesão ao tratamento medicamentoso; e 3 comparecimento às consultas, realização de exames e utilização de órteses. Foi considerada má adesão, quando realizado valor menor ou igual a 80% do prescrito. RESULTADOS: Um total de 53% dos pacientes apresentou boa adesão ao tratamento global, observada quando o cuidador possuía união estável (p = 0,006; 20 pacientes (20,2% apresentaram má adesão ao tratamento medicamentoso, relacionada à utilização de mais que três medicamentos diários (p = 0,047. As causas de má adesão ao tratamento foram esquecimento, recusa, dose incorreta ou falta de medicamento, problemas pessoais e dificuldades financeiras. CONCLUSÕES: Observamos boa adesão ao tratamento global nos pacientes cujos cuidadores possuíam união estável e má adesão ao tratamento medicamentoso nos pacientes que utilizavam mais que três tipos de medicamentos diariamente. Não houve associação entre as taxas de adesão ao tratamento e sexo, idade, tempo de diagnóstico e atividade da doença.

Doris E. Braun

2017-12-01

Full Text Available The moisture- and temperature dependent stabilities and interrelation pathways of the practically relevant solid forms of o-phenanthroline HCl (1 and neocuproine HCl (2 were investigated using thermal analytical techniques (HSM, DSC and TGA and gravimetric moisture sorption/desorption studies. The experimental stability data were correlated with the structural changes observed upon dehydration and the pairwise interaction and lattice energies calculated. For 1 the monohydrate was identified as the only stable form under conditions of RH typically found during production and storage, but at RH values >80% deliquescence occurs. The second compound, 2, forms an anhydrate and two different hydrates, mono- (2-Hy1 and trihydrate (2-Hy3. The 2-Hy1 structure was solved from SCXRD data and the anhydrate structure derived from a combination of PXRD and CSP. Depending on the environmental conditions (moisture either 2-Hy1 or 2-Hy3 is the most sable solid form of 2 at RT. The monohydrates 1-Hy1 and 2-Hy1 show a high enthalpic stabilization (≥20 kJ mol−1 relative to the anhydrates. The anhydrates are unstable at ambient conditions and readily transform to the monohydrates even in the presence of traces of moisture. This study demonstrates how the right combination of experiment and theory can unravel the properties and interconversion pathways of solid forms.

Zhou, Fei; Sun, Tian-Hu; Zhao, Lei; Pan, Xi-Wu; Lu, Shan

2015-01-01

The Artemisia annua L. β-pinene synthase QH6 was previously determined to be circadian-regulated at the transcriptional level, showing a rhythmic fluctuation of steady-state transcript abundances. Here we isolated both the genomic sequence and upstream promoter region of QH6. Different regulatory elements, such as G-box (TGACACGTGGCA, -421 bp from the translation initiation site) which might have effects on rhythmic gene expression, were found. Using the yeast one-hybrid and electrophoretic mobility shift assay (EMSA), we confirmed that the bZIP transcription factor HY5 binds to this motif of QH6. Studies with promoter truncations before and after this motif suggested that this G-box was important for the diurnal fluctuation of the transgenic β-glucuronidase gene (GUS) transcript abundance in Arabidopsis thaliana. GUS gene driven by the promoter region immediately after G-box showed an arrhythmic expression in both light/dark (LD) and constant dark (DD) conditions, whereas the control with G-box retained its fluctuation in both LD and DD. We further transformed A. thaliana with the luciferase gene (LUC) driven by an 1400 bp fragment upstream QH6 with its G-box intact or mutated, respectively. The luciferase activity assay showed that a peak in the early morning disappeared in the mutant. Gene expression analysis also demonstrated that the rhythmic expression of LUC was abolished in the hy5-1 mutant.

Um estímulo neutro, quando pareado a um estímulo aversivo incondicional, adquire a função de aversivo (condicional) e, indiretamente, também é capaz de suprimir operantes. Tal fenômeno foi denominado de “supressão condicionada” e está principalmente relacionado a certos estados emocionais, como a ansiedade. A literatura mostra que, em geral, o estímulo aversivo incondicional utilizado se restringe ao choque elétrico. Foram poucos os estímulos aversivos alternativos testados que...

Full Text Available Anthracnose is a destructive disease of the common bean (Phaseolus vulgaris L.. The Andean cultivar Hongyundou has been demonstrated to possess strong resistance to anthracnose race 81. To study the genetics of this resistance, the Hongyundou cultivar was crossed with a susceptible genotype Jingdou. Segregation of resistance for race 81 was assessed in the F2 population and F2:3 lines under controlled conditions. Results indicate that Hongyundou carries a single dominant gene for anthracnose resistance. An allele test by crossing Hongyundou with another resistant cultivar revealed that the resistance gene is in the Co-1 locus (therefore named Co-1HY. The physical distance between this locus and the two flanking markers was 46 kb, and this region included four candidate genes, namely, Phvul.001G243500, Phvul.001G243600, Phvul.001G243700 and Phvul.001G243800. These candidate genes encoded serine/threonine-protein kinases. Expression analysis of the four candidate genes in the resistant and susceptible cultivars under control condition and inoculated treatment revealed that all the four candidate genes are expressed at significantly higher levels in the resistant genotype than in susceptible genotype. Phvul.001G243600 and Phvul.001G243700 are expressed nearly 15-fold and 90-fold higher in the resistant genotype than in the susceptible parent before inoculation, respectively. Four candidate genes will provide useful information for further research into the resistance mechanism of anthracnose in common bean. The closely linked flanking markers identified here may be useful for transferring the resistance allele Co-1HY from Hongyundou to elite anthracnose susceptible common bean lines.

In recent years, the impact of aquatic invasive species on biodiversity has become a major global concern. In the Sacramento-San Joaquin Delta region in the Central Valley of California, USA, dense infestations of the invasive aquatic emergent weed, water hyacinth (Eichhornia crassipes) interfere with ecosystem functioning. This silent invader constantly encroaches into waterways, eventually making them unusable by people and uninhabitable to aquatic fauna. Quantifying and mapping invasive plant species in aquatic ecosystems is important for efficient management and implementation of mitigation measures. This paper evaluates the ability of hyperspectral imagery, acquired using the HyMap sensor, for mapping water hyacinth in the Sacramento-San Joaquin Delta region. Classification was performed on sixty-four flightlines acquired over the study site using a decision tree which incorporated Spectral Angle Mapper (SAM) algorithm, absorption feature parameters in the spectral region between 0.4 and 2.5μm, and spectral endmembers. The total image dataset was 130GB. Spectral signatures of other emergent aquatic species like pennywort (Hydrocotyle ranunculoides) and water primrose (Ludwigia peploides) showed close similarity with the water hyacinth spectrum, however, the decision tree successfully discriminated water hyacinth from other emergent aquatic vegetation species. The classification algorithm showed high accuracy (κ value = 0.8) in discriminating water hyacinth.

Previous studies have indicated that supplementation with probiotics might improve lipid metabolism. The objective of the study was to evaluate the effect of supplementation with probiotic strains Lactobacillus curvatus (L. curvatus) HY7601 and Lactobacillus plantarum (L. plantarum) KY1032 on triglyceride (TG) and apolipoprotein A-V (apo A-V) levels. A randomized, double-blinded, placebo-controlled study was conducted with 128 non-diabetic subjects with hypertriglyceridemia. Over a 12-week test period, the probiotic group consumed 2 g/day of a powdered supplement containing L. curvatus HY7601 and L. plantarum KY1032, whereas the placebo group consumed a powder lacking probiotics. After the treatment, the probiotic group showed an 18.3% (P  C genotype. The consumption of two probiotic strains for 12 weeks reduced TGs and increased the apo A-V and LDL particle size in hypertriglyceridemic subjects. This effect was more pronounced in subjects with higher levels of fasting TGs regardless of their APOA5 -1131T > C genotype. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available ResumoA crescente exposição a estressores na vida cotidiana aumentou significativamente a investigação da resposta ao estresse nas duas últimas décadas. Embora associada a consequências negativas, pois muitas patologias físicas e mentais são desencadeadas por exposição crônica a estressores, esta resposta é indispensável para sobrevivencia do indivíduo e é extremamente adaptativa quando ativada de forma aguda. Na parte I desta revisão foram abordados os conceitos de homestase e alostase e os sistemas fisiológicos ativados durante a resposta ao estresse. Na parte II serão discutidos fatores que modulam a resposta ao estresse tais como sexo, temperamento, períodos críticos do desenvolvimento e a presença ou ausência de suporte social. A interação entre os fatores genéticos e ambientais gera os perfis da resposta psicofisiológica que caracterizam os fenótipos de susceptibilidade e resiliência frente aos estressores e sua relação com uma patologia mental cada vez mais presente na sociedade moderna, o transtorno de estresse pós-traumático.

Integration of Xantrex HY-100 Hybrid Inverter with an AC Induction Wind Turbine

Corbus, D.; Newcomb, C.; Friedly, S.

2003-05-01

Several issues must be addressed before solid-state inverters can be used in wind-diesel systems with larger wind turbines. This project addresses those issues by using a commercial hybrid inverter designed for PV-diesel systems and modifying the inverter for use with an AC induction wind turbine. Another approach would have entailed building an inverter specifically for use with an AC induction wind turbine, but that was beyond the scope of this project. The inverter chosen for this project was a Xantrex HY-100, an inverter designed for PV systems. The unit consists of an inverter/rectifier bridge, a generator interface contactor, a battery charge controller, a hybrid controller, and the associated control electronics. Details of the inverter may be found in Appendix A. A twofold approach was taken to integrating the existing inverter for use with an AC induction wind turbine: 1) development of a detailed model to model both steady-state and transient behavior of the system, and 2) modification and testing of the inverter with an induction wind turbine based on the modeling results. This report describes these two tasks.

The HyPER Harvester Project resulted in the first full­scale design, fabrication and testing of two vertical­axis harvester prototypes at the Elephant Butte Irrigation District Drop 8 Station in Southern New Mexico. The design, followed by fabrication, and deployment clearly demonstrated the feasibility to manufacture and deploy harvester prototypes at low cost. While several issues common to irrigation canal systems have to be overcome, the electromechanical performance of the integrated turbine­generator system demonstrated proof­of­concept. Proof­of­concept includes 1) feasibility for using additive manufacturing techniques to fabricate Carbon­composite turbine­generator components at low cost, 2) ease of transportation and deployment, and 3) the harvester performance. The benefits of modularity were demonstrated in terms of rapid deployment at the Drop 8 Station. Scalability and adaptability were proven in terms of the custom­fitting characteristics that enabled rapid deployment. While keeping the same shape and form, the harvester can be easily adapted to any drop environment. Self­supporting ability makes the harvester design minimally intrusive on existing structures. There are two technical challenges ahead that have to be addressed. Irregular flow patterns in canal flow induce vertical oscillations due to pressure change across the impeller. Despite the nosecone in conventional Kaplan turbine design that ordinarily dampens oscillations, an effective coupling design is required to eliminate the hydrodynamic effect on the generating system. In arid areas where tumbleweed is present, a robust design to prevent trash entering the drop is required. The compact shape and form have an aesthetic appearance and appear to illustrate an environmentally friendly attribute. The systems­engineered design enables rapid manufacturing and assembly of desired size units that can be deployed at sites along U.S. waterways as small hydropower plants. There is

In the western Mediterranean basin, Corsica is at a strategic location for oceanographic and atmospheric studies in the framework of the Mediterranean projects HyMeX and ChArMEx. The development of a multi-site instrumented platform located on this island is the core of the project CORSiCA (Corsican Observatory for Research and Studies on Climate and Atmosphere-ocean environment). Several measurement sites are planned in various places in Corsica, but the main site gathering the largest panel of measurements will be located near Ersa at the northern tip of the island (Cap Corse). This area is relevant for many reasons: it is open to the Gulf of Genoa and is not impacted by local and regional anthropogenic inputs. In the close area of Ersa, five sites are particularly interesting: the Semaphore du Cap Corse belonging to the French Navy, the wind-mill farm on the mountain crest, two sites at Centuri and Tollare, and the Giraglia island. Contacts and partnerships have been established with local partners in Corsica: Departmental Centres of Météo-France (CDM 2B and CDM 2A), OEC (the Corsica environmental office, a regional agency co-funding the CORSiCA observatory), the University of Corsica, Qualitair Corse (the local air quality agency) and STARESO (Station de Recherches Sous-marines et Océanographiques, an oceanographic station located on the west coast of Corsica). CORSiCA will be operated for the HyMEx and ChArMEx Long Observation Period (LOP), Enhanced Observation Period (EOP) and Special Observation Periods (SOP). In addition, this observatory will also be of interest for the MERMEx experiment (Marine Ecosystems Response in the Mediterranean Experiment). Furthermore, it will be supported by the MOOSE network (Mediterranean Ocean Observing System on Environment) to maintain long-term observations of key atmospheric parameters on this site. In the present communication we will expose the scientific objectives and we will describe the type of instrumentation and

Full Text Available Due to the existence of new methodologies that have reduced the production costs of microbiological chitosan, this paper puts forward the use of agro-industrial residues in order to produce microbiological chitosan and to apply chitosan as an innovative resource for removing acid orange 7 (AO7 from wastewaters. The best culture conditions were selected by a full 24 factorial design, and the removal of the dye was optimized by a 23 central composite rotational design. The results showed that corn steep liquor (CSL is an agro-industrial residue that can be advantageously used to produce microbiological chitosan with yields up to 7.8 g/kg of substrate. FT-IR spectra of the product showed typical peak distributions like those of standard chitosan which confirmed the extracted product was chitosan-like. The efficiency of removing low concentrations of AO7 by using microbiological chitosan in distilled water (up to 89.96% and tap water (up to 80.60% was significantly higher than the efficiency of the control (chitosan obtained from crustaceans, suggesting that this biopolymer is a better economic alternative for discoloring wastewater where a low concentration of the dye is considered toxic. The high percentage recovery of AO7 from the microbiological chitosan particles used favors this biopolymer as a possible bleaching agent which may be reusable.

The bZIP transcription factor HY5 interacts with the promoter of the monoterpene synthase gene QH6 in modulating its rhythmic expression

Fei eZhou

2015-04-01

Full Text Available The Artemisia annua L. β-pinene synthase QH6 was previously determined to be circadian-regulated at the transcriptional level, showing a rhythmic fluctuation of steady-state transcript abundances. Here we isolated both the genomic sequence and upstream promoter region of QH6. Different regulatory elements, such as G-box (TGACACGTGGCA, -421 bp from the translation initiation site which might have effects on rhythmic gene expression, were found. Using the yeast one-hybrid and electrophoretic mobility shift assay (EMSA, we confirmed that the bZIP transcription factor HY5 binds to this motif of QH6. Studies with promoter truncations before and after this motif suggested that this G-box was important for the diurnal fluctuation of the transgenic β-glucuronidase gene (GUS transcript abundance in Arabidopsis thaliana. GUS gene driven by the promoter region immediately after G-box showed an arrhythmic expression in both light/dark (LD and constant dark (DD conditions, whereas the control with G-box retained its fluctuation in both LD and DD. We further transformed A. thaliana with the luciferase gene (LUC driven by an 1400 bp fragment upstream QH6 with its G-box intact or mutated, respectively. The luciferase activity assay showed that a peak in the early morning disappeared in the mutant. Gene expression analysis also demonstrated that the rhythmic expression of LUC was abolished in the hy5-1 mutant.

Shen, Junyu; Wang, Mei; Zhao, Liang; Zhang, Peili; Jiang, Jian; Liu, Jinxuan

2018-06-01

The development of highly efficient, robust, and cheap water oxidation electrodes is a major challenge in constructing industrially applicable electrolyzers for large-scale production of hydrogen from water. Herein we report a hierarchical stainless steel mesh electrode which features Ni(Fe)OxHy-coated self-supported nanocone arrays. Through a facile, mild, low-cost and readily scalable two-step fabrication procedure, the electrochemically active area of the optimized electrode is enlarged by a factor of 3.1 and the specific activity is enhanced by a factor of 250 at 265 mV overpotential compared with that of a corresponding pristine stainless steel mesh electrode. Moreover, the charge-transfer resistance is reduced from 4.47 Ω for the stainless steel mesh electrode to 0.13 Ω for the Ni(Fe)OxHy-coated nanocone array stainless steel mesh electrode. As a result, the cheap and easily fabricated electrode displays 280 and 303 mV low overpotentials to achieve high current densities of 500 and 1000 mA cmgeo-2, respectively, for oxygen evolution reaction in 1 M KOH. More importantly, the electrode exhibits a good stability over 340 h of chronopotentiometric test at 50 mA cmgeo-2 and only a slight attenuation (4.2%, ∼15 mV) in catalytic activity over 82 h electrolysis at a constant current density of 500 mA cmgeo-2.

En la primera parte del trabajo se presenta un panorama general de la importancia de los sistemas de transporte en las ciudades y cómo afectan la vida de sus habitantes. También se muestra la situación actual del transite en Bogotá y la necesidad de implantar sistemas alternativos de transporte. En la segunda parte, se propone el diseño de un sistema en línea de alquiler de bicicletas denominado Bicicleta Publica, que sea parte integral del Sistema integrado de transporte para Santafé de Bogotá. Para cumplir con este propósito se presentan los lineamientos generales mediante un plan de negocios, que conduzca a la creación de una empresa que administre el sistema y los servicios conexos. EI plan de negocios pretende cubrir la mayor parte de la ciudad, ubicando estaciones de bicicleta publica en diferentes lugares, principalmente en las áreas de influencia de las universidades, parques, centros comerciales y, en un futuro, en las estaciones de Transmilenio y el Metro. Esto le brinda al usuario la posibilidad de tomar una bicicleta en un punto determinado y retornarla en otra estación diferente a donde la alquiló inicialmente. Las ventajas de este mecanismo son apreciables, ya que no representa complicación alguna para el usuario debido a que puede usar la bicicleta el tiempo deseado sin preocuparse por aspectos tales como el estacionamiento, el clima o las diferentes actividades, para lo cual la bicicleta propia sería un completo inconveniente.

2018-06-01

We analyzed close to 7,000 observations from Robo-AO’s field M dwarf survey taken on the 2.1m Kitt Peak telescope. Results will help determine the total multiplicity fraction and multiplicity functions of M dwarfs, which are crucial steps towards understanding their evolution and formation mechanics. Through its robotic, laser-guided, and automated system, the Robo-AO instrument has yielded the largest adaptive-optics M dwarf survey to date. I developed a graphical user interface to quickly analyze this data. Initial data analysis included assessing data quality, checking the result from Robo-AO’s automatic reduction pipeline, and determining existence as well as the relative position of companions through a visual inspection. This program can be applied to other datasets and was successfully tested by re-analyzing observations from a separate Robo-AO survey. After a conservative initial cut for quality, over 350 companions were found within 4” of a primary star out of 2,746 high quality Robo-AO M dwarf observations, including four triple systems. Further observations were done with the Keck II telescope by using its NIRC2 imager to follow up on ten select targets for the existence and physical association of companions. Future research will yield insights into low-mass stellar formation and provide a database of nearby M dwarf multiples that will potentially assist ongoing and future surveys for planets around these stars, such as the NASA TESS mission.

Formation of hydroxyl groups and exchange with deuterium on NaHX and NaHY zeolites

International Nuclear Information System (INIS)

Kubelkova, L.; Novakova, J.

1976-01-01

Deammoniation and dehydroxylation of Na(NH 4 )X and Na(NH 4 )Y zeolites were compared. With the X type, both processes overlapped and proceeded more easily than with the Y type. Both H forms contained structural OH groups and hydroxyls denoted as SiOH, to which the 3740 cm -1 band in the IR spectrum was assigned. In addition, the NaHX zeolite contained OH groups characterized by the 3700 and 3600 cm -1 bands. Certain differences in the behaviour of NaHX and NaHY zeolites during deammoniation and dehydroxylation might be attributed to the presence of ''non-localizable'' H atoms. The active sites for the D 2 -OH exchange were probably formed during dehydroxylation. Hydrogen in SiOH groups was replaced by deuterium in both zeolite types more slowly than H atoms in other OH groups, which influenced the kinetic variations in the gaseous phase. The presence of water in the gaseous phase affected the kinetics and could distort the determination of the number of H atoms bound in the zeolites. (author)

Stadermann, Frank J.; Amari, Sachiko; Foote, John; Swan, Pat; Walker, Robert M.; Zinner, Ernst

1995-01-01

Previous secondary ion mass spectrometry (SIMS) studies of extended impact features from LDEF capture cell experiment AO187-2 showed that it is possible to distinguish natural and man-made particle impacts based on the chemical composition of projectile residues. The same measurement technique has now been applied to specially prepared gold target impacts from experiment AO187-1 in order to identify the origins of projectiles that left deposits too thin to be analyzed by conventional energy-dispersive x-ray (EDX) spectroscopy. The results indicate that SIMS may be the method of choice for the analysis of impact deposits on a variety of sample surfaces. SIMS was also used to determine the isotopic compositions of impact residues from several natural projectiles. Within the precision of the measurements all analyzed residues show isotopically normal compositions.

Although exercise is often recommended for managing osteoarthritis (OA), limited evidence-based exercise options are available for older adults with OA. This study compared the effects of Hatha yoga (HY) and aerobic/strengthening exercises (ASE) on knee OA. Randomized controlled trial with three arms design was used: HY, ASE, and education control. Both HY and ASE groups involved 8 weekly 45-min group classes with 2-4 days/week home practice sessions. Control group received OA education brochures and weekly phone calls from study staff. Standardized instruments were used to measure OA symptoms, physical function, mood, spiritual health, fear of falling, and quality of life at baseline, 4 and 8 weeks. HY/ASE adherences were assessed weekly using class attendance records and home practice video recordings. Primary analysis of the difference in the change from baseline was based on intent-to-treat and adjusted for baseline values. Eight-three adults with symptomatic knee OA completed the study (84% female; mean age 71.6 ± 8.0 years; mean BMI 29.0 ± 7.0 kg/m 2 ). Retention rate was 82%. Compared to the ASE group at 8 weeks, participants in the HY group had a significant improvement from baseline in perception of OA symptoms (-9.6 [95% CI -15.3, -4]; p = .001), anxiety (-1.4 [95% CI -2.7, -0]; p = .04), and fear of falling (-4.6 [-7.5, -1.7]; p = .002). There were no differences in class/home practice adherence between HY and ASE. Three non-serious adverse events were reported from the ASE group. Both HY and ASE improved symptoms and function but HY may have superior benefits for older adults with knee OA.

Holocene Evolution of Qing'ao Embayment, Southern China

Science.gov (United States)

Switzer, A. D.; Yu, F.; Chen, B.; Zheng, Z.; Wang, D.

2012-12-01

The Holocene evolution of the Qing'ao embayment, Nan'ao Island, southern China, is primarily the result of the interaction of tectonic activity, climate variation and changes in relative sea level. Characterizing the evolutionary history of the relatively small Qing'ao embayment during the Holocene will help improve our understanding of the driving mechanisms of coastal evolution in the area. To reconstruct the Holocene evolution history we analyzed the grain size, loss on ignition (LOI) and carbonate content of modern and core samples. Modern environmental analogs were examined in surface samples ranging from the coastal sand dunes through to offshore. The results of these modern samples suggest that dune sand (mean size of ~2.33Phi) are slightly finer than beach sand (mean size of 2.13Phi), and nearshore sediment is much coarser than offshore sediment (mean size of 5.90Phi). This modern analogs were then applied to 8 percussion cores from the Qing'ao embayment. A chronological framework obtained from 11 radiocarbon samples suggests that the embayment started to accept deposition since early Holocene, ~8500 cal. yr. BP. Three main phases of Holocene evolution were identified. A basin wide shell-rich sand sheet forms the basal Holocene facies and overlies clay rich presumably Pleistocene sediments or bedrock. This facies records an initial sedimentation phase associated with the early Holocene transgression into the embayment (~8500-6000 cal. yr. BP). The basal facies grades upward to a mixed sandy-mud facies which includes lagoonal clayey-silts, flood tide delta sands and records an estuarine phase lasting from ~6000-1000 cal. yr. BP that appears coincident with falling regional sea levels. Coincident with the estuarine phase is a period of coastal dune building recorded as yet undated massive sands that are found in the upper fill. Toward the end of the estuarine phase it is apparent that dune migration has restricted the lagoon entrance and that this was

Foram destacadas as singularidades desse nanico que começou como um jornal de bairro e que ganhou notoriedade nacional em pouco tempo, com a sua fala, o seu humor e as suas contradições. O Pasquim teve uma longa trajetória, permanecendo duas décadas em circulação (1969-1991 e, por conta disso, esse alternativo tem como principal característica o paradoxo. Ele existiu enquanto oposição ao regime ditatorial no pós-1964, e no período da redemocratização tornou-se aliado ao PDT no governo do Estado do Rio de Janeiro.

Performance of a MEMS-based AO-OCT system using Fourier Reconstruction

Energy Technology Data Exchange (ETDEWEB)

Evans, J; Zawadzki, R; Jones, S; Olivier, S; Werner, J S

2009-01-21

Adaptive optics (AO) and optical coherence tomography (OCT) are powerful imaging modalities that, when combined, can provide high-resolution (3.5 {micro}m isotropic), 3-D images of the retina. The AO-OCT system at UC Davis has demonstrated the utility of this technology for microscopic, volumetric, in vivo retinal imaging. The current system uses an AOptix bimorph deformable mirror (DM) for low-order, high-stroke correction and a 140-actuator Boston Micromachines DM for high-order correction. Developments to improve performance or functionality of the instrument are on-going. Based on previous work in system characterization we have focused on improved AO control. We present preliminary results and remaining challenges for a newly implemented Fourier transform reconstructor (FTR). The previously reported error budget analysis is also reviewed and updated, with consideration of how to improve both the amount of residual error and the robustness of the system. Careful characterization of the AO system will lead to improved performance and inform the design of future systems.

HyFlux - Part I: Regional modeling of methane flux from near-seafloor gas hydrate deposits on continental margins MacDonald, I.R., Asper, V., Garcia, O., Kastner, M., Leifer, I., Naehr, T.H., Solomon, E., Yvon-Lewis, S., and Zimmer, B. The Dept. of Energy National Energy Technology Laboratory (DOE/NETL) has recently awarded a project entitled HyFlux: "Remote sensing and sea-truth measurements of methane flux to the atmosphere." The project will address this problem with a combined effort of satellite remote sensing and data collection at proven sites in the Gulf of Mexico where gas hydrate releases gas to the water column. Submarine gas hydrate is a large pool of greenhouse gas that may interact with the atmosphere over geologic time to affect climate cycles. In the near term, the magnitude of methane reaching the atmosphere from gas hydrate on continental margins is poorly known because 1) gas hydrate is exposed to metastable oceanic conditions in shallow, dispersed deposits that are poorly imaged by standard geophysical techniques and 2) the consumption of methane in marine sediments and in the water column is subject to uncertainty. The northern GOM is a prolific hydrocarbon province where rapid migration of oil, gases, and brines from deep subsurface petroleum reservoirs occurs through faults generated by salt tectonics. Focused expulsion of hydrocarbons is manifested at the seafloor by gas vents, gas hydrates, oil seeps, chemosynthetic biological communities, and mud volcanoes. Where hydrocarbon seeps occur in depths below the hydrate stability zone (~500m), rapid flux of gas will feed shallow deposits of gas hydrate that potentially interact with water column temperature changes; oil released from seeps forms sea-surface features that can be detected in remote-sensing images. The regional phase of the project will quantify verifiable sources of methane (and oil) the Gulf of Mexico continental margin and selected margins (e.g. Pakistan Margin, South China Sea

2018-01-01

We analyzed over 7,000 observations from Robo-AO’s field M dwarf survey taken on the 2.1m Kitt Peak telescope. Results will help determine the multiplicity fraction of M dwarfs as a function of primary mass, which is a crucial step towards understanding their evolution and formation mechanics. Through its robotic, laser-guided, and automated system, the Robo-AO instrument has yielded the largest adaptive-optics M dwarf survey to date. I developed a graphical user interface to quickly analyze this data. Initial data analysis included assessing data quality, checking the result from Robo-AO’s automatic reduction pipeline, and determining existence as well as the relative position of companions through a visual inspection. This program can be applied to other datasets and was successfully tested by re-analyzing observations from a separate Robo-AO survey. Following the preliminary results from this data analysis tool, further observations were done with the Keck II telescope by using its NIRC2 imager to follow up on ten select targets for the existence and physical association of companions. After a conservative initial cut for quality, 356 companions were found within 4” of a primary star out of 2,746 high quality Robo-AO M dwarf observations, including four triple systems. We will present a preliminary estimate for the multiplicity rate of wide M dwarf companions after accounting for observation limitations and the completeness of our search. Future research will yield insights into low-mass stellar formation and provide a database of nearby M dwarf multiples that will potentially assist ongoing and future surveys for planets around these stars, such as the NASA TESS mission.

Full Text Available OBJETIVO: Analisar instrumento de medição da adesão ao tratamento da hipertensão por meio da "Teoria da Resposta ao Item". MÉTODOS: Estudo analítico com 406 hipertensos com complicações associadas, atendidos na atenção básica em Fortaleza, CE, 2011, pela "Teoria da Resposta ao Item". As etapas de execução foram: teste de dimensionalidade, calibração dos itens; tratamento dos dados e construção da escala, analisadas com base no modelo de resposta gradual. Estudo da dimensionalidade do instrumento foi feito pela análise da matriz de correlação policórica e análise fatorial de informação completa. Utilizou-se o software Multilog para calibração dos itens e estimação dos escores. RESULTADOS: Os itens referentes ao tratamento medicamentoso foram os mais diretamente relacionados à adesão, enquanto aqueles referentes ao tratamento não medicamentoso precisam ser reformulados, pois possuíram menor quantidade de informação psicométrica e baixa discriminação. A independência dos itens, o reduzido número de níveis da escala e as baixas variâncias explicadas no ajuste dos modelos mostraram as principais fragilidades do instrumento analisado. A "Teoria da Resposta ao Item" mostrou-se relevante para análise, pois avaliou o respondente quanto à adesão ao tratamento da hipertensão, ao nível de dificuldade dos itens e à sua capacidade de discriminação entre indivíduos com diferentes níveis de adesão, o que gerou maior quantidade de informação. CONCLUSÕES: O instrumento analisado é limitado para medir a adesão ao tratamento da hipertensão, mediante análise pela "Teoria da Resposta ao Item", e necessita de ajustes. A adequada formulação dos itens é importante para medir precisamente o traço latente desejado.

Mare Humorum, centered at 24°S and 39°W is a mare basin of Nectarian age present at the southwestern end of Oceanus Procellarum towards the nearside of the Moon. It displays several rings, in varying states of exposure and preservation. The area is entirely flooded by mare material that constitutes its major recognizable event. In the present study, investigation of mineralogy of the basaltic flows of Mare Humorum basin have been undertaken to understand its compositional character, especially the pyroxene variability. Primarily, high-resolution data of Hyperspectral Imager (HySI) (Spatial resolution, 80m/pixel) from Chandrayaan-I mission of Indian Space Research Organization (I.S.R.O) have been used. Besides, Moon Mineralogy Mapper M3 data (140 m/pixel) from the same mission, with its full coverage of the area have been used as base of whole study. The spectral properties of pyroxenes have utilized for characterization of mare lithology and to demarcate the various spectral units based on pyroxene-variability. The compositional analysis results, thus obtained, are studied and discussed for understanding the basaltic evolution of the Humorum basin.

Full Text Available Na atualidade existe uma grande preocupação com a busca pelo desenvolvimento de combustíveis alternativos para os motores de ciclo a diesel, a fim de reduzir os impactos causados por este combustível ao meio ambiente, principalmente quanto a emissões de poluentes e dependência de combustíveis derivados do petróleo; estes são fatores que contribuem e intensificam os estudos para novas pesquisas tendo como rotas de produção a busca por fontes de energias renováveis. Por conseguinte o biodiesel entra como forma de diminuir esse impacto ambiental em virtude de ser uma fonte de energia renovável, ecológica, não tóxico e de baixo risco de explosão. A preocupação quanto à questão de obtenção de energia sem ser prejudicial ao meio ambiente, tornou o assunto sobre o biodiesel cada vez mais difundido e discutido quanto a sua produção e utilização no setor de transporte. Este estudo tem como objetivo a análise dos aspectos sobre a utilização do biodiesel em empresas de transporte coletivo, situadas na região de Joinville - SC. O trabalho foi realizado utilizando dados reais coletados nas próprias empresas objetivando a quantificação financeira da substituição do diesel pelo combustível alternativo, outro fator analisado foi o incentivo dos órgãos governamentais quanto à utilização desses combustíveis alternativos tomando como base o projeto de lei 310/2009, que prevê algumas desonerações para o uso desses combustíveis. Foi realizada uma abordagem sobre os impactos ambientais, através da análise dos testes de opacidade de ambos os combustíveis. A pesquisa se caracterizou pela análise comparativa do emprego do diesel mineral (100% e o biodiesel, em diferentes proporções, no sistema de transporte coletivo da cidade.

When doing high angular resolution imaging with adaptive optics (AO), it is of crucial importance to have an accurate knowledge of the point spread function associated with each observation. Applications are numerous: image contrast enhancement by deconvolution, improved photometry and astrometry, as well as real time AO performance evaluation. In this paper, we present our work on automatic PSF reconstruction based on control loop data, acquired simultaneously with the observation. This problem has already been solved for curvature AO systems. To adapt this method to another type of WFS, a specific analytical noise propagation model must be established. For the Shack-Hartmann WFS, we are able to derive a very accurate estimate of the noise on each slope measurement, based on the covariances of the WFS CCD pixel values in the corresponding sub-aperture. These covariances can be either derived off-line from telemetry data, or calculated by the AO computer during the acquisition. We present improved methods to determine 1) r0 from the DM drive commands, which includes an estimation of the outer scale L0 2) the contribution of the high spatial frequency component of the turbulent phase, which is not corrected by the AO system and is scaled by r0. This new method has been implemented in an IDL-based software called OPERA (Performance of Adaptive Optics). We have tested OPERA on Altair, the recently commissioned Gemini-North AO system, and present our preliminary results. We also summarize the AO data required to run OPERA on any other AO system.

The hydrophobicity of some photosensitizers can induce aggregation in biological systems, which consequently reduces photodynamic activity. The conjugation of photosensitizers with nanocarrier systems can potentially be used to overcome this problem. The objective of this study was to prepare and characterise hypericin-loaded solid lipid nanoparticles (Hy-SLN) for use in photodynamic therapy (PDT). SLN were prepared using the ultrasonication technique, and their physicochemical properties were characterised. The mean particle size was found to be 153 nm, with a low polydispersity index of 0.28. One of the major advantages of the SLN formulation is its high entrapment efficiency (EE%). Hy-SLN showed greater than 80% EE and a drug loading capacity of 5.22% (w/w). To determine the photodynamic efficiency of Hy before and after encapsulation in SLN, the rate constants for the photodecomposition of two (1)O2 trapping reagents, DPBF and AU, were determined. These rate constants exhibited an increase of 60% and 50% for each method, respectively, which is most likely due to an increase in the lifetime of the triplet state caused by the increase in solubility. Hy-SLN presented a 30% increase in cell uptake and a correlated improvement of 26% in cytotoxicity. Thus, all these advantages suggest that Hy-loaded SLN has potential for use in PDT.

LONG HYPOCOTYL5 (HY5) and STF1 (Soybean TGACG-motif binding Factor 1) are two related bZIP transcription factors that play a positive role in photomorphogenesis and hormonal signaling. In this study, we compared full length STF1 and truncated STF1 overexpression lines and found that the C-terminal 133 amino acids (194–306) possess all the HY5-like function in Arabidopsis. The STF1-DC1 mutant (1–306), with a 20 amino acid deletion at the carboxy terminus, failed to complement the hy5 mutant phenotype, which suggests an intact C-terminus is required for STF1 function. To understand the role of the C-terminal domain in photomorphogenesis we used a yeast two-hybrid screen to isolate proteins that bind to the STF1 C-terminus. We isolated three soybean cDNAs encoding the zinc-finger proteins GmSTO, GmSTH, and GmSTH2, which interact with STF1. These proteins belong to a family of B-box zinc finger proteins that include Arabidopsis SALT TOLERANCE (STO) and STO HOMOLOG (STH) and STH2, which play a role in light-dependent development and gene expression. The C-terminal 63 amino acids of STF1, containing a leucine zipper and the two N-terminal B-boxes, contains the domain involved in interactions between STF1 and GmSTO. In addition, we identified an interaction between soybean COP1 (GmCOP1) and GmSTO and GmSTH, as well as STF1, which strongly suggests the presence of a similar regulatory circuit for light signaling in soybean as in Arabidopsis. This study shows that photomorphogenic control requires complex molecular interactions among several different classes of transcription factors such as bZIP, B-box factors, and COP1, a ubiquitin ligase. - Highlights: • STF1 interact with GmSTO, GmSTH and GmSTH2. • The bZIP transcription factor STF1 requires an intact C-terminal domain for STF1 function. • STF1 and GmSTO are nuclear proteins.

Full Text Available Curaçao, one of the five islands of the Dutch Caribbean federation called the Netherlands Antilles, currently stands at a crossroad of constitutional reform. In the context of these changes at the political level, it is logical that national identities are being redefined and repositioned. The developments in the fashioning of national identities in Curaçao deserve attention locally but also regionally. How do people in Curaçao construct national identities in daily life? How is a national collective constructed on the one hand, and how are differences with other collectivities constructed on the other hand? The historical context of constitutional changes that have occurred over the years is considered as well as an examination of the present discourse on constitutional reform. These identity issues are then placed within a wider Caribbean context.  Resumen: La complejidad de la construcción de la identidad nacional en Curaçao,en el Caribe holandés Curaçao, una de las cinco islas de la federación caribeña neerlandesa llamada Antillas Holandesas, se encuentra hoy en día en una encrucijada de reformas constitucionales.

Requirements Modeling with the Aspect-oriented User Requirements Notation (AoURN): A Case Study

Science.gov (United States)

Mussbacher, Gunter; Amyot, Daniel; Araújo, João; Moreira, Ana

The User Requirements Notation (URN) is a recent ITU-T standard that supports requirements engineering activities. The Aspect-oriented URN (AoURN) adds aspect-oriented concepts to URN, creating a unified framework that allows for scenario-based, goal-oriented, and aspect-oriented modeling. AoURN is applied to the car crash crisis management system (CCCMS), modeling its functional and non-functional requirements (NFRs). AoURN generally models all use cases, NFRs, and stakeholders as individual concerns and provides general guidelines for concern identification. AoURN handles interactions between concerns, capturing their dependencies and conflicts as well as the resolutions. We present a qualitative comparison of aspect-oriented techniques for scenario-based and goal-oriented requirements engineering. An evaluation carried out based on the metrics adapted from literature and a task-based evaluation suggest that AoURN models are more scalable than URN models and exhibit better modularity, reusability, and maintainability.

Full Text Available Hyperspectral high spatial resolution HyMap data are used to map mine waste from massive sulfide ore deposits, mostly abandoned, on the Iberian Pyrite Belt (southwest Spain. Mine dams, mill tailings and mine dumps in variable states of pyrite oxidation are recognizable. The interpretation of hyperspectral remote sensing requires specific algorithms able to manage high dimensional data compared to multispectral data. The routine of image processing methods used to extract information from hyperspectral data to map geological features is explained, as well as the sequence of algorithms used to produce maps of the mine sites. The mineralogical identification capability of algorithms to produce maps based on archive spectral libraries is discussed. Trends of mineral growth differ spectrally over time according to the geological setting and the recovery state of the mine site. Subtle mineralogical changes are enhanced using the spectral response as indicators of pyrite oxidation intensity of the mine waste piles and pyrite mud tailings. The changes in the surface of the mill tailings deserve a detailed description, as the surfaces are inaccessible to direct observation. Such mineralogical changes respond faithfully to industrial activities or the influence of climate when undisturbed by human influence.

The experiment was conducted with 160 Hy- Line W36 layer hens (47 weeks of age, kept in cages of 25 cm, distributed in a completely randomized design, with eight birds and four replications. The control diet was on a corn and soybean meal base and the other diets had 50 or 100% of substitution of corn by sorghum, low tannin. The paprika, when supplemented, was added in 500 g t-1 or 1,000 g t-1. to the ration of low or high sorghum levels, respectively. The substitution of the corn by sorghum did not affect the performance of laying hens, but decreased the yolk pigmentation. When the natural pigment was added, in both dosages, the yolk pigmentation was higher than that obtained from the control diet, but the level of 1,000 g t-1. reduced the performance of layers.

2016-04-01

The combined effects of the Arctic Oscillation (AO) and Western Pacific (WP) teleconnection pattern on the East Asian winter monsoon (EAWM) over the last 56 years (1958/59-2013/2014) were investigated using NCEP/NCAR reanalysis data (Park and Ahn, 2015). The study results revealed that the effect of the AO on winter temperature in East Asia could be changed depending on the phases of the WP pattern in the North Pacific. The negative relationship between the EAWM and the AO increased when the AO and WP were in-phase with each other. Hence, when winter negative (positive) AO was accompanied by negative (positive) WP, negative (positive) temperature anomalies were dominant across the entire East Asia region. Conversely, when the AO and WP were of-of-phase, the winter temperature anomaly in East Asia did not show distinct changes. Furthermore, from the perspective of stationary planetary waves, the zonal wavenumber-2 patterns of sea level pressure and geopotential height at 500hPa circulation strengthened when the AO and WP were in-phase but were not significant for the out-of-phase condition. It explained the possible mechanism of the combined effects of the AO and WP on the circulation related to EAWM. Reference Park, H.-J., and J.-B.

Full Text Available O objetivo do presente trabalho foi acompanhar o desenvolvimento imunológico dos neonatos caninos, a fim de avaliar a imunidade celular pela análise dos leucócitos e linfócitos totais e das subpopulações de linfócitos T (CD4+ e CD8+ pela técnica de citometria de fluxo. Foram utilizados 30 cães neonatos de ambos os sexos, sem raça definida, aos três, 10, 17, 24, 31, 38 e 45 dias de idade. A contagem de leucócitos totais aos 45 dias (11.639±3.574 foi significativamente maior que no terceiro dia de idade (8.740±1.812 (P<0,05; não houve diferença entre a contagem total de linfócitos aos 45 dias em relação ao terceiro dia de idade. Quanto às subpopulações de LT CD4+ e LT CD8+, os percentuais de LT CD4+, aos três dias de idade (24,9±16,8%, foram inferiores quando comparados à média entre o 10°, o 24° e o 31°dia (35,5%, e os de CD8+, ao terceiro dia, menores em relação às médias do 10° e do 31° dia de idade. Pode-se concluir que as subpopulações de LT CD4+ e CD8+ sofrem oscilações durante o desenvolvimento pós-natal, sendo estas crescentes em relação aos níveis obtidos aos três dias de idade. A relação CD4+:CD8+ mostrou superioridade para o primeiro tipo celular, sendo que a maior relação entre CD4+ e CD8+ ocorreu no terceiro dia de idade. Com base nos resultados obtidos neste estudo, notaram-se as diferenças semanais nas populações linfocitárias, o que demonstra a dinâmica dessas células durante o período neonatal.

Full Text Available O conceito de Qualidade de Vida é usado para medir as condições de vida de um ser humano, já a palavra vulnerabilidade refere-se à chance das pessoas estarem expostas ao adoecer. Objetivou-se analisar possíveis relações entre percepção de qualidade de vida e a vulnerabilidade ao estresse no trabalho em enfermeiros, técnicos e auxiliares de enfermagem que atuam na UTI e no setor de emergência de um hospital público. Utilizou-se o instrumento de qualidade de vida da Organização Mundial da Saúde, WHOQOL-Bref e a Escala de Vulnerabilidade ao Estresse no Trabalho. Encontrou-se, em relação ao setor de trabalho, diferença significativa apenas para Qualidade de vida total. Portanto pode-se afirmar que os profissionais que atuam na UTI possuem maior percepção de qualidade de vida quando comparados aos do SUS. Na correlação entre os dois instrumentos, o domínio meio ambiente do WHOQOL-Bref correlacionou-se negativa e significativamente com todos os fatores da EVENT, indicando que a percepção da pessoa em relação aos diversos aspectos do meio em que vive tem relação com a vulnerabilidade ao estresse.

O protestantismo em Portugal (sécs. XIX-XX): linhas de força da sua história e historiografia

OpenAIRE

Santos, Luís Aguiar

2000-01-01

A marginalidade do protestantismo em Portugal não deve atribuir-se à sua repressão por uma sociedade supostamente autoritária e clerical. Pelo contrário, o protestantismo sofreu a concorrência de uma Igreja hegemónica já instalada e de sistemas de crença seculares alternativos à mensagem cristã, enquanto ao longo dos séculos XIX e XX se assistiu a uma lenta evolução de uma tolerância “de facto” a uma tolerância “de jure”. As várias denominações protestantes são caracterizadas e classificadas ...

Jorge Henrique Santos Saldanha

Full Text Available INTRODUÇÃO: As Lesões por Esforços Repetitivos/Distúrbios Osteomusculares Relacionados ao Trabalho (LER/DORT causam afastamento do trabalho de uma grande parcela de trabalhadores. OBJETIVO: Entender e sistematizar de que forma os fatores relacionados ao retorno ao trabalho (RT de trabalhadores acometidos por LER/DORT são descritos na literatura como facilitadores ou barreiras. MÉTODOS: Revisão crítica de literatura do período de janeiro de 2005 a outubro de 2010 disponível nas bases Lilacs, MedLine e SciELO. As informações foram sistematizadas em três categorias de fatores que influenciam o RT e como facilitadores ou barreiras - de ordem pessoal, de ordem organizacional e relacionadas às características dos serviços, sistemas e políticas. RESULTADOS: Dos 633 artigos inicialmente levantados, 21 atenderam aos critérios de inclusão. Fatores identificados como mais relevantes: de ordem pessoal - dor, fatores psicossociais, afastamento do trabalho; organizacionais - modificações nos postos de trabalho, demanda psicológica do trabalho, apoio organizacional, apoio de colegas e da chefia; relacionados aos serviços, sistemas e políticas - programa de retorno ao trabalho, tempo de afastamento e serviços de apoio. CONCLUSÃO: O estudo evidenciou que o RT é um processo complexo, que demanda políticas intersetoriais, cooperação técnica e pactuação de metas entre os atores envolvidos no processo.

Full Text Available A incorporação de amido ao polímero poli (butilenoadipatoco-tereftalato (PBAT através de blendas com alto teor de amido pode ser uma alternativa para obter embalagens biodegradáveis, minimizar custos e o uso de recursos não renováveis. No entanto, a adição de amido aumenta a permeabilidade ao vapor de água (PVA. A incorporação em filmes com amido de substâncias como óleos vegetais e surfactantes pode diminuir a hidrofilicidade, favorecendo as aplicações destes como embalagens. A hidrofilicidade dos filmes elaborados por blendas de amido/PBAT adicionados de óleo de soja (OS e tween 80 (TW foi avaliada considerando o efeito do OS e TW nas isotermas de sorção dos filmes, na PVA e nos coeficientes de difusão (Dw e solubilidade (β do vapor de água. Filmes com OS com ou sem TW apresentaram menor quantidade de água de sorção, sendo os filmes com menores quantidades de OS e sem TW menos hidrofílicos e menos permeáveis aos vapores de água. A adição de OS reduziu os valores de β e Dw dos filmes de amido/PBAT. O efeito foi relacionado com o aumento das porções hidrofóbicas e da compatibilidade entre o amido e PBAT na presença de OS.Incorporating starch into the poly(butylene adipate-co-terephthalate (PBAT polymer by means of blends with high starch contents is a possible option for producing biodegradable packaging using renewable resources and reducing costs. However, the addition of starch increases the water vapour permeability (WVP. The incorporation of substances as lipids and surfactants can reduce the hydrophilicity of films containing starch, favouring their use as packaging. The hydrophilicity of films produced from blends of starch/PBAT with added soybean oil (SO and tween 80 (TW was studied. The effects of these substances on the sorption isotherm, on the WVP and on the water vapour diffusion (Dw and solubility (β coefficients of the films were evaluated.

Full Text Available Com o crescente consumo de flores e plantas ornamentais de vaso, a busca por elementos alternativos para substratos torna-se necessária, a fim de reduzir os custos da produção. Além disso, é importante quantificar as características físico-hídricas de forma a estabelecer o calendário de irrigações com base nesses materiais. A partir disso, este trabalho teve por objetivos avaliar o desempenho e o consumo de água de Kalanchoe blossfeldiana Poelln, cultivar 'Gold Jewel', em 10 substratos alternativos, e definir os mais indicados para a produção comercial nas condições ambientais da região centro-oeste do Estado do Rio Grande do Sul. Foram testados substratos compostos por diferentes proporções de casca de arroz carbonizada, cinzas de casca de arroz, matéria orgânica doméstica decomposta, esterco bovino e esterco de aves. O experimento foi conduzido em casa de vegetação, em delineamento experimental inteiramente casualizado, com quatro repetições. No final do ciclo, foram avaliados: altura, número de folhas, número de inflorescências, número de flores e diâmetro da copa das plantas nos diferentes tratamentos. Por meio dos resultados, pode-se concluir que, para produção de plantas, os substratos mais indicados são 100% em volume de matéria orgânica e 50% em volume de matéria orgânica +50% em volume de esterco bovino.With the increase in the flowers and ornamental crops consumption, the search for alternative elements to the substrates, became to necessary reduce spends the production. Besides, it's important to quantify the physics - hydric characteristics and the manner to establish the calendar of the irrigations using these materials. Based in this, this research had as the mainly purpose to evaluate the performance and the water consumption of the Kalanchoe blossfeldiana Poelln, cv. Gold Jewel in ten alternative substrates and to define the most indicated to the commercial production in environmental
