Foliar Sprays to Control Insects in Wheat, Painter, Va, 1993

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract Wheat was planted on 13 Nov 1993 at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot was 25 ft long by 5 ft wide and replicated 4 times in a randomized, complete block design. Sprays were applied on 2 May using a 3-nozzle flat fan boom backpack sprayer delivering 20 gal water/acre at 40 psi, when CLB pressure was at or near the treatment threshold of 1 larva/flag leaf in most plots. Numbers of CLB larvae/50 flag leaves and numbers of EGA/50 ears were counted in each plot on the dates indicated in the table. Percent defoliation was rated on 12 May on 25 randomly chosen flag leaves/plot, and the plots were harvested on 7 Jul.
hep–ph/9409440 Theoretical Update of the Semileptonic Branching Ratio of B Mesons

Field: Physics and Astronomy (Physical Sciences)

We reconsider the prediction of the semileptonic branching ratio of B mesons, using the recent calculation [1] of the radiative corrections with account for finite quark masses in nonleptonic decays and taking into account 1/m 2 b corrections. For the semileptonic branching ratio we obtain BSL = (11.8±1.6) % using pole quark masses and BSL = (11.0± 1.9) % using running MS quark masses. The uncertainty is dominated by unknown higher order perturbative corrections. We conclude that the present accuracy of the theoretical analysis does not allow to state a significant disagreement with the experimental results. However, our re-analysis of the decay b → ccs yields an increase of (35 ±11) % due to nextto-leading order corrections including mass dependent terms, which further emphasizes the problem of the average charm quark content of the final states in B decays.
CFD analysis of the effect of pressure gradients on the separation efficiency of a generic air curtain

Field: Engineering (Physical Sciences)

The aim of this study is to evaluate the performance of a generic air curtain configuration when it is exposed to cross-jet forces derived from systematic variations in environmental conditions, namely pressure gradients between the indoor and outdoor environments. The analysis is performed based on computational fluid dynamics (CFD) simulations on verified computational grids and validated with water-tank experiments and field measurements.
A Case of a Highly Drug-Resistant HIV Detected after Irregular Use of a Self-Prescribed Antiretroviral Drug

Field: Medicine (Health Sciences)

Patients who bypass medical institutions to obtain drugs to treat human immunodeficiency virus (HIV) infections often take the medications irregularly or self-interrupt their own therapy; this is problematic because it leads to drug resistance. In addition, the presence/absence of drug resistance is a determinant of the success of HIV treatment. Thus, testing for drug resistance is essential for initial drug selection.
[Metabolic evolution of hypertonic dehydration with combined treatment of fluidotherapy and peritoneal dialysis: revision of 22 infants (author's transl)].

Field: Medicine (Health Sciences)

Metabolic evolution of osmolarity, natraemia, chloremia, kaliemia and uremia of 22 infants with severe hypertonic dehydration, treated with fluidotherapy and peritoneal dialysis, is revised. Peritoneal dialysis was prepared in accordance with a special method for this metabolic condition. The serie was divided into two groups, according to initial value of natraemia: more or less than 170 mEq./l. Average decreases per hour of osmolarity, natraemia and chloremia were evaluated, as well as the influence of peritoneal dialysis on body fluids composition. Indication of peritoneal dialysis specially prepared for severe cases is discussed.
Greenhouse gas reporting of the LULUCF sector for the UNFCCC and Kyoto Protocol : background to the Dutch NIR 2013

Field: Environmental Science (Physical Sciences)

This report provides a complete description and background information of the Dutch National System for Greenhouse gas Reporting of the LULUCF sector and the Dutch LULUCF submission under the Kyoto Protocol for the 2013 submission of The Netherlands. The 2013 submission reports greenhouse gas emissions over the year 2011. It includes detailed description of the methodologies used to calculate activity data and emissions and it gives the full text of the NIR-II for KP-LULUCF, as well as a description of the table-by-table methodologies, choices and motivations. In 2011 afforestation and reforestation activities produced a sink of 458.66 Gg CO2 equivalents while deforestation caused an emission of 838.67 Gg CO2 equivalents. These values were based on changes in above-and belowground biomass, dead wood, litter and soil (mineral as well as organic), and agricultural lime application on deforested areas.

On the Improvement of Linear Discrete System Stability: The Maximal Set of the $F$-Admissible Initial States

Field: Mathematics (Physical Sciences)

The linear controlled discrete system { x(i + 1) = Ax(i) + Bu(i) i ≥ 0, x(0) = x0, u(i) = Fx(i), i ≥ 0, y(i) = Cx(i), i ≥ 0, is supposed to be output stabilizable, i.e., limi→+∞ y(i) = 0. To improve the stability of the system we propose in this paper a theoretical and algorithmic characterization of all the initial states x0 for which y(i) ∈ B(0, αi), for all i ≥ 0, where B(0, αi) is the ball of center 0 and radius αi, the sequence (αi)i is appropriately chosen “(αi)i can be interpreted as a desired degree of stability.” The case of discrete delayed systems is also considered.

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Objective To develop competitive ELISA method for determining the concentration of haemophilus influenza type b polysaccharide( PRP). Methods PRP-Ty was set as coating antigen and poliasccharide as competition antigen,comparison were made between the two reactions against antisera of haemophilus influenza type b. The accuracy and precision of the method were validated accordingly. Results The optimal coating concentration of PRP-Ty and serum dilution factor was 1 ∶ 400,and 1 ∶ 40 K respectively. Quantitation of PRP concentration was linear from 6. 25ug /ml-100ug / ml,with lower limit of detection being 3. 13ug / ml. The regression equation was B / B0=-34. 328[PRP]+105. 03 with RSQ = 0. 995. The coefficient of variation of intra-assay and inter-assay was 3. 4%-6. 5% and 8. 48%respectively. The recovery rate of PRP in culture medium was 95. 7%. Conclusion The competitive ELISA method showed both high accuracy and precision,and thus can be used for detection of haemophilus influenza type b polysaccharide.
Rotary Transformer for Contactless Excitation of Synchronous Machines Fed Through Neutral Conductor

Field: Engineering (Physical Sciences)

This paper presents a brushless excitation system for inverter operated electrical excited synchronous machines without the necessity of an additional inverter for the excitation system. In order to fulfill the requirement of a brushless system, a rotary transformer transfers the power to the rotor field winding inductively. A rectifier connected to the rotating secondary winding of the transformer provides a DC-voltage to the rotor winding. The neutral conductor runs from the star point of the three stator phases trough the stationary primary winding of the rotating transformer and back to the center point between the intermediate circuit capacitors. A common mode voltage (CMV) with fixed frequency and variable amplitude is added to the 3-phase modulation for the inverter working with pulse width modulation (PWM). Since the star point is connected, a current driven by the CMV will flow in the neutral conductor. Through the amplitude of the CMV the voltage supplying the primary winding of the transformer can be regulated, which has a direct impact on the DC-voltage of the field winding i.e. the excitation.
Nanomechanical Property Maps of Breast Cancer Cells As Determined by Multiharmonic Atomic Force Microscopy Reveal Syk-Dependent Changes in Microtubule Stability Mediated by MAP1B

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The Syk protein-tyrosine kinase, a well-characterized modulator of immune recognition receptor signaling, also plays important, but poorly characterized, roles in tumor progression, acting as an inhibitor of cellular motility and metastasis in highly invasive cancer cells. Multiharmonic atomic force microscopy (AFM) was used to map nanomechanical properties of live MDA-MB-231 breast cancer cells either lacking or expressing Syk. The expression of Syk dramatically altered the cellular topography, reduced cell height, increased elasticity, increased viscosity, and allowed visualization of a more substantial microtubule network. The microtubules of Syk-expressing cells were more stable to nocodazole-induced depolymerization and were more highly acetylated than those of Syk-deficient cells. Silencing of MAP1B, a major substrate for Syk in MDA-MB-231 cells, attenuated Syk-dependent microtubule stability and reversed much of the effect of Syk on cellular topography, stiffness, and viscosity. This study illustrates the use of multiharmonic AFM both to quantitatively map the local nanomechanical properties of living cells and to identify the underlying mechanisms by which these properties are modulated by signal transduction machinery.
Agricultural Management and Soil Carbon Storage in Surface vs. Deep Layers

Field: Agricultural and Biological Sciences (Life Sciences)

Soil C sequestration research has historically focused on the top 0 to 30 cm of the soil profile, ignoring deeper portions that might also respond to management. In this study we sampled soils along a 10‐treatment management intensity gradient to a 1‐m depth to test the hypothesis that C gains in surface soils are offset by losses lower in the profile. Treatments included four annual cropping systems in a corn ( Zea mays )‐soybean ( Glycine max )‐ wheat ( Triticum aestivum ) rotation, perennial alfalfa ( Medicago sativa ) and poplar ( Populus x euramericana ), and four unmanaged successional systems. The annual grain systems included conventionally tilled, no‐tillage, reduced‐input, and organic systems. Unmanaged treatments included a 12‐yr‐old early successional community, two 50‐yr‐old mid‐successional communities, and a mature forest never cleared for agriculture. All treatments were replicated three to six times and all cropping systems were 12 yr post‐establishment when sampled. Surface soil C concentrations and total C pools were significantly greater under no‐till, organic, early successional, never‐tilled mid‐successional, and deciduous forest systems than in the conventionally managed cropping system ( p ≤ 0.05, n = 3–6 replicate sites). We found no consistent differences in soil C at depth, despite intensive sampling (30–60 deep soil cores per treatment). Carbon concentrations in the B/Bt and Bt2/C horizons were lower and two and three times more variable, respectively, than in surface soils. We found no evidence for C gains in the surface soils of no‐till and other treatments to be either offset or magnified by carbon change at depth.
Profiles of immune infiltration in abdominal aortic aneurysm and their associated marker genes: a gene expression-based study

Field: Medicine (Health Sciences)

Immune-mediated inflammation plays a key role in the pathology of abdominal aortic aneurysm (AAA). We aimed to use a computational approach to profile the immune infiltration patterns and related core genes in AAA samples based on the overexpression of gene signatures. The microarray datasets of AAA and normal abdominal tissues were acquired from gene expression omnibus (GEO) database. We evaluated the composition of immune infiltrates through microenvironment cell populations (MCP)-counter. Weighted gene correlation network analysis (WGCNA) was employed to construct the co-expression network and extract gene information in the most relevant module. Functional and pathway enrichment analysis was performed and immune infiltration related core genes were screened. AAA tissues had a higher level of infiltration by cytotoxic lymphocytes, NK cells, T cells, fibroblasts, myeloid dendritic cells, and neutrophils than normal aorta. The red module was strongly correlated with the infiltrating levels of T cells and cytotoxic lymphocytes. Gene ontology (GO) and pathway analyses revealed that genes in the most relevant module were mainly enriched in T cell activation, regulation of lymphocyte activation, cytokine-cytokine receptor interaction, and chemokine signaling pathway, etc. The expression of GZMK, CCL5, GZMA, CD2, and EOMES showed significant correlations with cytotoxic lymphocytes, while CD247, CD2, CD6, RASGRP1, and CD48 expression were positively associated with T cell infiltration. In conclusion, we comprehensively analyzed profiles of infiltrated immune cells in AAA tissues and their associated marker genes. Our data may provide a novel clue to indicate the underlying molecular mechanisms of AAA formation in terms of immune infiltration.
Relationship between superconducting transition temperature, specific heat, and electrical resistivity in Nb-V alloys

Field: Physics and Astronomy (Physical Sciences)

A study is made of the correlation between the superconducting transition temperature Tc and the Debye temperature ΘD, electronic specific heat γ, and the derivative with respect to temperature of the electrical resistivity (dp/dT)T&gt;ΘD in alloys of the system Nb-V. The measured values of Tc are in good qualitative agreement with values calculated from the microscopic theory of superconductivity in the strong-coupling approximation, confirming the validity of this approximation for these alloys.
Amitriptyline Once Daily vs Three Times Daily in Depressed Outpatients

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Two dosage schedules of amitriptyline hydrochloride, once daily vs three times daily, were compared in a group of 124 nonpsychotic depressed outpatients. After four weeks of treatment, patients on the once daily schedule had improved significantly more than patients receiving multiple doses on both physician and patient measures. The two groups did not differ in their attrition rates nor in reporting of side effects. Since treatment response to the tricyclic antidepressants is often delayed, once-daily dosage seems to offer a distinct advantage over more conventional multiple doses in depressed outpatients.
DIFFERENTIAL SENSITIVITY OF PROPHASE POLLEN TUBE CHROMOSOMES TO X-RAYS AND ULTRAVIOLET RADIATION

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

1. Through use of the pollen tube technique it has been possible to study the sensitivity of prophase stages to x-rays and ultraviolet, and to correlate the varying sensitivity with changes in the generative nucleus of Tradescantia. 2. Sensitivity to ultraviolet decreases from the 2 hour stage until at 11 hours after germination there is no further production of breaks. The 0 and 1 hour stages show a decreased sensitivity over the 2 hour stage but it has been suggested that this is not due to a decreased sensitivity but to shielding by the pollen wall. 3. Sensitivity to x-rays rises to a peak at the 4 hour stage, but then subsides until no breaks are realized (at a dose of 370.8 r) after the 10 hour stage. In this respect the effects of x-rays and ultraviolet are similar. Each type of x-ray break shows its own individual trend. 4. Correlation of x-ray breaks with changes in the generative nucleus indicates that the important events determining the sensitivity of the chromosomes to breakage are the uptake of water at the time of germination and the movement involved in spiralization. The total absence of breaks after the 11 hour stage is not understood. 5. The changing sensitivity to ultraviolet may depend on any one or all of three factors: (a) the nucleic acid cycle, (b) changes in the matrix, and (c) the number of subdivisions in the chromosome. These are discussed although their relative importance is not known.
Computational fluid dynamic model of a thin layer cascading photobioreactor

Field: Chemical Engineering (Physical Sciences)

Large-scale microalgae cultures grown in photobioreactors are often either light-limited or light-inhibited. Cascading photobioreactors aim at solving this problem by bringing together a high microalgal biomass concentration, a geometrically thin culture and significant turbolence which protects the microalgae photosynthetic system by exposing the cells to an alternative light intensity. The present project deals with the development of a computational fluid dynamic model of a cascading photobioreactor to investigate the macromixing influence of its design and operating parameters.
Aberrant Structural–Functional Coupling of Large-Scale Brain Networks in Older Women With Subthreshold Depression

Field: Neuroscience (Life Sciences)

Abstract Objectives Subthreshold depression (SD) is common in the older population, more so in females than males, and can lead to serious physical and mental ill-health. However, the underlying neurobiology remains unclear. This study used multimodal magnetic resonance imaging (MRI) to investigate the topological organization and coupling of the structural and functional brain networks in older women with SD. Methods We constructed the structural network from diffusion MRI and the functional network from resting-state functional MRI in 50 older women with SD and 52 demographically matched older women healthy controls (HC). We used graph theory analysis to examine the topological properties of functional and structural networks, and structural–functional connectivity (SC–FC) coupling, and their potential relationship to depressive symptoms. Results Globally, compared with older women HC, the older women with SD showed lower local efficiency in the structural network but not the functional network. Locally, older women with SD showed altered convergent nodal metrics in the default mode, salience, and sensorimotor network regions in both structural and functional networks. Moreover, SC–FC coupling reduced in older women with SD compared to older women HC. These network metric alterations were correlated with depressive symptoms. Discussion Older women with SD showed alterations in both structural and functional networks, and in their coupling, which throw light on the role of large-scale brain networks in older female SD.

Heavy nucleus acoustic periodic waves in a degenerate relativistic magneto-rotating quantum plasma

Field: Physics and Astronomy (Physical Sciences)

The study of heavy nucleus acoustic (HNA) periodic and solitary waves in degenerate relativistic magneto-rotating quantum plasma (DRMQP) composed of relativistic degenerate electrons, light nuclei and non-degenerate mobile heavy nuclei is presented. Reductive perturbation technique is adopted to derive the Korteweg–de Vries (KdV) type equation for studying the characteristics of HNA periodic waves. Further energy balance equation is derived by using Sagdeev potential approach and HNA cnoidal wave solution is determined. Only positive potential nonlinear periodic and solitary structures are observed. The impact of number density ratio, charge density, magnetic field strength and rotational effect is analyzed on the characteristics of HNA cnoidal and solitary waves. The results of this investigation may shed light on the salient features of different nonlinear HNA waves in different astrophysical environments, especially in white dwarfs.
Atlas of Midpoint Algebra

Field: Mathematics (Physical Sciences)

Summary. This article is a continuation of [4]. We have established a one-to-one correspondence between midpoint algebras and groups with the operator 1 . In general we shall say that a given midpoint algebra M and a group V are w-assotiated iff w is an atlas from M to V. At the beginning of the paper a few facts which rather belong to [3], [5] are proved.
Motion attention based frame-level bit allocation scheme for H.264

Field: Computer Science (Physical Sciences)

Rate control plays a major role in video coding and multimedia streaming. A well-designed rate control scheme should pursue both the objective quality and subjective quality. However, existing H.264 rate control algorithms mainly aim at improving the objective quality without consideration the perception of human view system (HVS). In this paper, we propose a novel rate control algorithm based on local motion attention. The bits allocated to each frame are proportional to the local motion activity in it, and more bits are allocated to the frame with strong local motion attention. Experiment results show that our method not only enhances the coding quality in the frames with strong local motion attention but also reduces the temporal PSNR fluctuation across frames up to 22.15%.
