Sputter ion pump element pumping speed measurement with the help of a Monte Carlo code

As part of the design of the vacuum system of a new Synchrotron Light Source for Brazil – SIRIUS, the Vacuum Group from the Brazilian Synchrotron Light Laboratory (LNLS) proposed the pumping speed study of a sputter ion pump element assembled inside the vacuum chamber. This configuration aims to reduce components attached to the chamber enabling an easier alignment procedure and a conductance enhancement to pumped gases. The study was carried out by experimental measurements and numerical simulations using Monte Carlo method. The measurements and Monte Carlo calculations results presented a good agreement, with errors less than 10%. Further, inserting the element in the vacuum chamber enhanced maximum pumping speed when compared with the manufacturer’s data, due to the conductance’s increase for gases.
Micro-morphological Analysis of the Effect of Sampling by the Volumetric Ring Method on Soil Structure

This report investigates the effect of sampling by the volumetric ring method on pore size number and shape distributions. Soil porosity was analyzed using the micromorphological image analysis technique, which helped to explain soil structure changes near the border of samples collected in cylinders and provided detailed information about pore shape, number, and size distribution variations along the samples. Compaction due to sampling affects mainly large irregular and rounded pores of the soils utilized in this study. When evaluating inaccuracies in density measurements due to the compacted regions caused by the sampling device the average soil bulk density for each soil resulted in the ranges of 1.72 ± 0.05 g.cm −3 for Geric Ferralsol soil, 1.66 ± 0.03 g.cm −3 for Eutric Nitosol soil and 1.33 ± 0.05 g.cm −3 for Rhodic Ferralsol soil, respectively. When calculating the average soil bulk density over smaller regions, e.g. in the center of each sample (area of 17.14 mm 2 ) results reduced to 1.64 ± 0.05 .
Determinants of Capital Structure Choices by Listed Firms in Zimbabwe under Hyperinflation and Dollarization

The paper uses panel data, from 2000 to 2013, to examine the key determinants of capital structure choices for Zimbabwe listed firms under hyperinflation and dollarization by: (1) providing a reduced form model which isolates the key factors consistent with the unique situation for Zimbabwe; (2) testing the existence of a non-linear relationship between leverage and capital structure factors; (3) ascertaining the significance of marginal effects of explanatory variables due to inflation; and (4) establishing how the behaviour of firm managers influenced the choice of leverage. In an inflationary environment, the main factors explaining the choice of debt were profitability, non-debt tax shield, payout ratio, ownership POLICY BRIEF Determinants of Capital Structure Choices by Listed Firms in Zimbabwe under Hyperinflation and Dollarization
Relative profiling of L-tryptophan derivatives from selected edible mushrooms as psychoactive nutraceuticals to inhibit P-glycoprotein: a paradigm to contest blood-brain barrier

Depression is a mental illness and is considered to be a global threat. It is designated as burden of disease. There is therefore an intense need to improve the therapeutic response of antidepressants. India beholds a wide fraction (Agaricus bisporus and Pleurotus ostreatus ) as a vital source of non-hallucinogenic indole compounds. The amino acids L-tryptophan and 5-hydroxytryptophan (5-HTP) are precursors of serotonin. 5-HTP is a potential antidepressant that can cross the blood-brain barrier (BBB) at a high rate and is converted into serotonin more efficiently. Drug delivery across this blockade remains a challenge due to the stimulation of efflux pump receptors called permeability glycoprotein (P-gp). This work reports a comparative phytochemical assay and profiling of non-hallucinogenic tryptophan metabolites using HPLC from two organic extracts of edible mushrooms. The efficacy of the eluted compounds was authenticated as P-gp inhibitors with in vitro and in silico studies. The following four derivatives were obtained from the methanol and ethanol extracts of the mushrooms: 5-hydroxy-L-tryptophan (5HTR), 5-hydroxy tryptamine (5-HT), L-tryptophan (L-Trp), and tryptamine (TA). In vitro and molecular docking studies targeting P-gp (minimum energy: –64.38 and –83.93 kcal/mol, respectively) substantiated the ability of mushroom-derived metabolites to facilitate drug delivery in the brain. This study verified that mushrooms containing non-hallucinogenic metabolites can act as psychoactive nutraceuticals that are significant for enhancing mental health. The high therapeutic efficacy, these mushrooms can serve as ideal neurological drug leads to fortify treatment for mental illness.
Rules versus Discretion: Empirical Evidence from Indonesia ́s Intergovernmental Transfer system

Can formula-based transfers effectively limit favoritism and political patronage in public funds allocations? Formula-based transfers that tie the allocation of public funds to local development indicators are often seen as one effective measure to reduce special-interest politics, although the limited empirical evidence on formula-based transfers suggests the opposite. However, the few existing empirical studies evaluate formula-based transfers without comparing them to a more discretionary counterfactual, such as a nonformula-based institutional transfer design. Indonesia's institutional public grant design provides a unique opportunity to compare these two transfer designs within the same country for the first time. My analysis allows me to investigate special interests in public funds allocations holding the political system, the observation period, and the government officials involved constant, while varying the institutional transfer design. Using a fixed-effects model on an unbalanced panel data set of 428 Indonesian districts from 20042017, the results show that non-formula-based special allocation grants are systematically biased toward Indonesia’s national Budget Commission members' home districts. The home districts of the same set of Budget Commission members do not, in contrast, receive significantly higher per capita transfers under the formula-based transfer design. These results illustrate that—in contrast to its more discretionary alternative—a formula-based institutional public grant design can effectively limit public fund manipulations by government officials.

A Review Toxoplasmosis

Toxoplasma gondii is an intracellular protozoan infecting humans and animals. The term toxoplasmosis refers to the clinical or pathological disease caused by Toxoplasma gondii and T. gondii infection for an asymptomatic primary infection or persistence of the parasite in tissues. When considering toxoplasmosis in the differential diagnosis of a patient’s illness, it is important to keep in mind that emphasis should not be placed on whether the patient has or has not been exposed to cats. Transmission of parasites essentially occurs without knowledge of the patient and may be unrelated to direct exposure to a cat (e.g., by ingestion of vegetables or water contaminated with oocysts or ingestion of undercooked meat contaminated with cysts). Serologic investigation of a cat to establish whether it is a potential source of the infection should be discouraged; the prevalence of T. gondii antibodies among cats in a given locale is usually similar to their prevalence in humans. Seropositivity in the cat does not predict shedding of oocysts. For clinical purposes, toxoplasmosis can be divided for convenience into five infection categories, including those (Abbasi et al., 2003) acquired by immunocompetent patients, (Abgrall et al., 2001) acquired during pregnancy, (Abgrall et al., 2001) acquired congenitally; and (Afonso et al., 2009) acquired by or reactivated in immunodeficient patients, and including (Afonso et al., 2009; Windal, 2015) ocular infections. In any of the above mentioned categories, clinical presentations are not specific for toxoplasmosis, and a wide differential diagnosis must be considered. Furthermore, diagnostic methods and their interpretations may differ for each clinical classification.
Cultural and morphological characterization of isolates of Alternaria alternata (Fr.) Keissler, causing chrysanthemum leaf blight

Fungal blights are among the major concern for limiting the cultivation and production of many ornamental and flowering plants. Chrysanthemum is an important cut flower with great export potential. However, it is infected by many pathogens in the protected cultivation. Diseased chrysanthemum samples were collected from chrysanthemum gardens, nurseries and farmers orchards in the Latur district for cultural and morphological characterization of Alternaria alternata. The collected isolates of A. alternata, from various varieties / hybrids of chrysanthemum were characterized, based on their mycelial growth, growth rate, colony appearance, colony shape and margin, sporulation and concentric zonation and morphological characters (mycelial width, conidia dimensions, beak length and numbers of vertical and horizontal septa). The highest colony growth was found in Ac-1, Ac-3 and ac-4 followed byAc-5. Excellent sporulation was found in isolates such as Ac-1, Ac-3, Ac-5 and Ac-9. Four isolates Ac10, Ac9, Ac-8 and Ac-7 showed large sized mycelial width ranged from 7.15-9.48 μm. Ac-9 and Ac-10 isolates was showed large sized conidia (42.1760.29 L X 9.40-11.77 W). Three isolates Ac-5, Ac-9 and Ac-8 showed large sized beak length ranged from 13.5215. 29 μm, whereas horizontal septation ranged from 1-9 and vertical septation from 1-5.
A THERMODYNAMIC MODEL APPLICABLE TO LIQUID – GAMMA – GAMMA PRIME PHASE EQUILIBRIUM IN SUPERALLOYS

Abstract A thermodynamic model has been developed to address the gamma, gamma prime and liquid phase equilibrium for dilute single crystal gas turbine alloys such as CMSX-10. The model is based on a review of the Ni-X (X = Al, Co, Cr, Re, Ta, W) binary systems where the observed binary phase diagrams are well reproduced with self-consistent thermodynamic models that incorporate, when available, measured thermodynamic properties. These models are then interpolated using the Kohler scheme to address the gamma–gamma prime equilibrium observed in the related Al-Ni-X ternary systems. The gamma and liquid phases are modelled using a substitutional solution formalism; the gamma prime phase is modelled as the stoichiometric compound Ni3Al into which are dissolved compounds of the Ni3X type. The role of coherency in superalloy microstructure and the importance of a sound knowledge of constituent binary systems are discussed. The calculated phase equilibrium compositions and phase transformation temperatures are compared to the literature data for CMSX-10. Un modèle thermodynamique a été développé pour représenter l’équilibre des phases gamma, gamma prime, et liquide, dans les alliages monocristallins dilué de turbines à gaz. Ce modèle est basé sur une revue critique des systèmes binaires Ni-X, (X = Al, Co, Cr, Re, Ta, W) où les diagrammes d’équilibre sont bien reproduits par les modèles thermodynamiques incorporant des mesures expérimentales de propriétés thermodynamiques. Ces systèmes sont interpolés au moyen du schéma Kohler pour examiner l’équilibre observé dans les systèmes ternaires Al-Ni-X. Les phases gamma et liquide sont représentées par un formalisme basé sur une solution substitutionelle, la phase gamma prime étant modélisée à partir d’un composé stoechiométrique Ni3Al dans lequel les composés de type Ni3X sont dissous. Le rôle de la cohérence dans la microstructure des superalliages, et l’importance de la connaissance propre des systèmes binaires, sont discutées. Les compositions d’équilibre et les températures de transformation des phases calculées sont en accord avec les données de la littérature pour l’alliage commercial CMSX-10.
Effect of NPK fertilization on growth and yield of guava under high density planting

A field experiment was conducted during 2012-13 and 2013-14 to study the effect of different levels of nitrogen, phosphorus and potassium individually and in combinations on growth and yield parameters of young bearing guava grown under high density planting system. Experimental findings revealed that, plant growth was significantly influenced by applied nutrients. Plant height, plant spread, plant volume, length of shoot, number of leaves, leaf area and chlorophyll content showed significant improvement with the application of 300 g nitrogen, 150 g phosphorus and 150 g potassium per plant during both the years of experimentation. Second order interactions also influenced the growth characters of guava and it was observed that combination of 300 g N + 150 g P2O5 + 150 g K2O per plant recorded maximum plant growth. Yield attributing characters viz., number of flowers per shoot, fruit set, fruit drop, fruit weight were significantly influenced by the increasing levels of applied nutrients. The results obtained on pooled basis reveals that treatment consisting 300 g N + 150 g P2O5 + 150 g K2O per plant was noteworthy in increasing yield parameters of guava over all other combinations and control.
Molecular Understanding of the Open‐Circuit Voltage of Polymer:Fullerene Solar Cells

The origin of open‐circuit voltage (VOC) was studied for polymer solar cells based on a blend of poly(3‐hexylthiophene) (P3HT) and seven fullerene derivatives with different LUMO energy levels and side chains. The temperature dependence of J–V characteristics was analyzed by an equivalent circuit model. As a result, VOC increased with the decrease in the saturation current density J0 of the device. Furthermore, J0 was dependent on the activation energy EA for J0, which is related to the HOMO–LUMO energy gap between P3HT and fullerene. Interestingly, the pre‐exponential term J00 for J0 was larger for pristine fullerenes than for substituted fullerene derivatives, suggesting that the electronic coupling between molecules also has substantial impact on VOC. This is probably because the recombination is non‐diffusion‐lmilited reaction depending on electron transfer at the P3HT/fullerene interface. In summary, the origin of VOC is ascribed not only to the relative HOMO–LUMO energy gap but also to the electronic couplings between fullerene/fullerene and polymer/fullerene.
Suppurative BCG Lymphadenitis and the Importance of Microbiology Investigations – A Case Report

Suppurative BCG lymphadenitis can easily be overlooked, as it mimics other diseases such as tuberculous lymphadenitis. A case of a three-month old female infant who received the BCG vaccination at birth presented with isolated left axillary mass at two months of age. She was initially treated as lymph node abscess but was referred to the hospital due to the increasing size of the swelling. Needle aspiration was done and the microbiology analysis came out positive for acid-fast bacilli. She was planned for syrup isoniazid; however, the management team withheld treatment until they were certain of the identity of the bacteria. The bacteria was confirmed by the molecular method to be Mycobacterium bovis BCG strain. The case report highlights the importance of the microbiology investigations for appropriate management in this case.

A SECURE AND DYNAMIC MULTI-KEYWORD RANKED SEARCH SCHEME OVER ENCRYPTED CLOUD DATA

: - Nowadays, the unique and safest way of stowing and conveying data is cloud computing. Automated computing and, on demand computing is another names of cloud computing. The method in which common podium or secluded server is used in the collection of data from several sources which can be easily accessible on their requirement. Due to recent advances in wireless communication technologies, there has been a rapid growth in wireless sensor networks research during the past few decades. Many novel architectures, protocols, algorithms, and applications have been proposed and implemented. The efficiency of these networks is highly dependent on routing protocols directly affecting the network life-time. In sparse wireless sensor networks, a mobile robot is usually exploited to collect the sensing data. Each sensor has a limited transmission range and the mobile robot must get into the coverage of each sensor node to obtain the sensing data. To minimize the energy consumption on the traveling of the mobile robot, it is significant to plan a data collection path with the minimum length to complete the data collection task. In this project, we observe that this problem can be formulated as traveling salesman problem with neighborhoods, which is known to be NP-hard. To address this problem, we apply the concept of artificial bee colony (ABC) and design an ABC-based routing algorithm.
6. Pubertal status and emotional, school and social functioning-LSAC Annual Statistical Report 2015

Puberty is a major developmental milestone involving the physical changes whereby a child’s body matures into an adult body physiologically capable of sexual reproduction. The onset of puberty marks the transition from childhood to adolescence. The beginning of adolescence involves rapid physical growth, changes in body composition and changes in most body systems—including the neuroendocrine axis, bone size and mineralisation, and the cardiovascular system—along with emotional and cognitive changes (Dubas, Graber, & Petersen, 1991). A better understanding of the factors associated with the timing of the onset of puberty is not only important for understanding variable patterns of physical development but also has important clinical, health and educational implications.
The role of contract and relationship norms in the success of Information Technology Outsourcing

Information technology outsourcing provides several advantages for organizations, such as reducing the cost of ownership of IT products/services, providing rapid access to modern technologies. However, when the outsourcing relationship is not managed effectively, the desired results are not always achieved. This article aims to reveal the role of contract and relationship norms in the success of the IT outsourcing relationship, by focusing on the Turkish domestic market. Firstly, the measurement scales of the research were developed by making use of the previous studies and field interviews. Then the measurement model and hypotheses were tested using the partial least square method. It was concluded that both contract and relationship norms affect IT outsourcing success, but the contract is more effective than relationship norms for IT outsourcing success. Furthermore, it is concluded that relationship norms have a mediating effect between the contract and IT outsourcing success.

The Relationship between Risk and Return: An Empirical Study of Kuwait Stock Exchange

This paper examines the relationship between beta and returns of the industrial portfolio in Kuwait Stock Exchange using monthly data from June 2001 to October 2009. The study uses the M-GARCH (1.1) to estimate the time–varying beta and shows how the mean of time varying beta differs from the constant beta. It also shows that the unconditional relationship is rejected in this Market. The Study tested the model of Pettengill et al (1995), conditional on segmenting the up and down market. It was found that the results did not support this model where the market is down. Moreover, this Study concludes that the CAPM does not work in this small emerging market.
Environmental diagnosis of forest fragments belonging to the Santa Genebrinha ecological corridor, Campinas, São Paulo

Green areas, whether located in urban or rural environments, play an important role in maintaining ecological systems that provide vital environmental services for the quality of life of populations. In this sense, the present study assessed the environmental damage in the forest remnants that make up the Santa Genebrinha ecological corridor in Campinas city, São Paulo State, to identify limitations in the implementation and maintenance of this corridor. Initially, we surveyed geoindicators and the distribution of forest remnants in the Ribeirão Anhumas watershed, where the corridor is inserted. Subsequently, we developed an impact assessment matrix to quantify the main environmental damages affecting the forest remnants that make up this corridor. The results allowed us to identify the most impacting actions on the corridor: agriculture/monoculture, deforestation, burning, urbanization, and land use and occupation, with quantification (Q) averages of -7.6; -8.3; -7.3; -8.1; and -7.3, respectively, resulting in a high damage percentage (66.7%) for each action. The diagnosis pointed to local scope, direct incidence, and current temporality, reinforcing the need to consider these factors for implementation and management of the quoted corridor.
Microfluidic micromixer as a tool to overcome solvent incompatibilities in two-dimensional liquid chromatography

We report a micromilled, pressure-resistant mixing chip for application in on-line comprehensive two-dimensional liquid chromatography (LC×LC). This microfluidic mixer is based on chaotic advection generated in grooved microchannels, and can be operated at flow rates compatible with LC×LC (0.1-1 mL/min). The design of this chip was optimized and tested in our previous work in the transparent and flexible silicon rubber material, polydimethylsiloxane (PDMS). In this work, the microfluidic chip was micromilled in rigid cyclic-olefin copolymer (COC) substrate in order to better withstand the high pressure environment of LC×LC. Two micromilled parts were bonded using solvent-vapour-assisted bonding under elevated temperature and pressure. A specially designed, robust, low-deadvolume interface allows direct connection of the microfluidic chip to an LC×LC system using standardized HPLC connectors. Thus-fabricated chips can withstand pressures of 200 bar. The chip was successfully implemented in a comprehensive two-dimensional HILIC×RP-LC system for improved separation and identification of various oligomeric series in nylon polymer (polyamide) samples. Initial trials of the micromixer in a simple modulator at the interface between the two columns yielded chromatographic performance similar to that obtained with commercially available mixing units. However, with the grooved micromixer, it was possible to mix rapidly within the same flow rate range in a volume, which was 30 times smaller than the commercially available micromixers, opening a route to utilization of microfluidic mixers in the conventional equipment.
