Executivas: carreira, maternidade, amores e preconceitos

Este articulo analiza la percepcion de las mujeres ejecutivas que llegaron a la cumbre de la jerarquia organizacional de las grandes empresas en Brasil, sobre los desafios de su carrera. El referencial teorico explora los determinantes de exito en la carrera: estructura, capital humano, familia, socioeconomicos, inversion en el trabajo y expectativa de recompensa. El articulo se basa en un metodo mixto cuantitativo-cualitativo. La encuesta cuantitativa conto con 965 encuestados, de los cuales 222 eran mujeres, en una muestra de 344 empresas entre las mayores del pais. La encuesta cualitativa conto con 263 encuestados, entre los cuales 48 eran mujeres, en 10 grandes empresas de varios sectores. Los resultados muestran que los obstaculos en direccion a las altas exigencias de la carrera son colosales: prejuicios arraigados; presion del reloj biologico; sobrecarga por el cuidado de los hijos versus jornada de trabajo muy extensa; dificultades con su pareja. A pesar de todo, aunque esten insatisfechas con el desequilibrio entre el tiempo de trabajo y el de no trabajo, las mujeres ejecutivas continuan apostando en la carrera.
Why Don’t People Take their Medicine? Experimental Evidence from Kenya

The standard public finance approach to health care in less developed countries involves identifying and heavily subsidizing priority health interventions that generate treatment externalities (e.g., vaccines). A popular recent approach instead argues that health education, community mobilization, and cost-recovery are also necessary for successful programs. We focus on the case of intestinal worms – which affect one in four people worldwide – and provide evidence from a series of randomized evaluations that subsidies are more effective than other factors in influencing deworming drug take-up among schoolchildren in Kenya. An effort to educate children on worm prevention was ineffective at changing behavior. Those who were randomly exposed to more information about the deworming drugs through their social networks were significantly less likely to take them. A verbal commitment “mobilization” intervention from social psychology led to significantly lower treatment rates. In contrast, drug take-up was highly sensitive to cost: the introduction of a small fee led to a massive eighty percent reduction in treatment rates (relative to free treatment). Cost-sharing appears particularly inappropriate for medical conditions characterized by large treatment externalities – like worms and other infectious diseases. The results suggest that, to promote new health technologies in less developed countries, scarce public resources should be focused on subsidies. * Contact: Edward Miguel (emiguel@econ.berkeley.edu) or Michael Kremer (mkremer@fas.harvard.edu).

Gene Expression Programming for Prediction of Flow Discharge in Compound Channels

There are many studies on the hydraulic calculation of steady uniform flows in compound open channels. Based on these studies, various methods have been developed with different assumptions. In general, these methods either have long computations or need numerical solution of differential equations. Furthermore, their accuracy for all compound channels with different geometric and hydraulic conditions may not be guaranteed. In this paper, to overcome with these limitations, a new simple and dimensionless equation has been proposed based on gene-expression programming (GEP), which is an extension to genetic programming (GP). In this equation only three parameters (e.g. depth ratio, coherence and ratio of computed total flow discharge to bankful discharge) have been used to simplify its applications for hydraulic and river engineers. By compiling 394 stage-discharge data from laboratories and fields of 30 compound channels, this new equation has been applied to estimate the flow conveyance capacity. The proposed GEP approach gives satisfactory results (R2 = 0.98 and RMSE = 0.32) compared to traditional method (VDCM) with R2 = 0.69 and RMSE = 1.72 for flow discharge computations.
Adapting Cognitive-Behavior Therapy for Insomnia in Cancer Patients

Insomnia disorder is common in patients undergoing cancer treatment. There is compelling evidence demonstrating that cognitive-behavioral therapy for insomnia (CBT-I) should be the initial treatment, but there has been insufficient research has been conducted among cancer patients. This population presents with unique physical and psychosocial health issues that may interfere with standard CBT-I and addressing these issues can play a role in improving treatment adherence and efficacy. We explore potential adaptations that can be made to standard CBT-I for cancer patients. Further research for this growing population is essential. Sleep Med Res
Influence of Ferrous sulphate on growth and alpha-a Amylase production for Aspergillus fumigatus NTCC1222

Stringent government regulations and increasing public awareness is forcing chemical industries to incorporate environment friendly products and processes. Biotechnological applications, in industries, thus, hold great future. Microorganisms and their metabolites/enzymes provide a number of eminenteconomic as well as environment friendly solutions for such industries. Amylases are one of the most important industrial enzymes. Commercial production of amylases requires selection of the best of production conditions. This study evaluates the influence of varying concentration of Ferrous sulphate (Fe2+) on microbial growth and amylase production for Aspergillus, Aspergillus fumigatus NTCC1222. Ferrous sulphate enhanced growth (concentration of 100mg/L) by 1.83%, compared to the control. In contrast, it decreased amylase activity at all concentrations tested. As the concentration of ferrous sulphate increased, the amylase activity decreased. Amylases are metalloenzymes and the inhibition in amylase activity observed in the presence of ferrous ions may be due to competition between the exogenous cation and the protein associated cation, resulting in reduced metalloenzyme activity. Further studies will aim to evaluate the effect of different ferrous salts and different forms of iron on amylase production by Aspergillus fumigatus NTCC1222.

Self-mode-locked semiconductor disk lasers

In the last decade, vertical-external-cavity surface-emitting lasers (VECSELs) have become promising sources of ultrashort laser pulses. While the mode-locked operation has been strongly relying on costly semiconductor saturable-absorber mirrors for many years, new techniques have been found for pulse formation. Mode-locking VECSELs are nowadays not only achievable by using a variety of saturable absorbers, but also by using a saturable-absorber-free technique referred to as self-mode-locking (SML), which is to be highlighted here.
Studies on nutritional requirements of Pseudomonas aeruginosa forlipase production

A nutritional requirement for the lipase production by Pseudomonas aeruginosa strain was investigated. The bacterial strain was isolated from municipal sewage and it was culture with different nutritional composition. The maximum lipase activity was obtained with maltose as the sole carbon source 6.5 Uml-1, followed by lactose 4.6Uml- 1. The various salts used the best results were observed with calcium chloride 4.6 Uml-1as and sodium chloride an inorganic source. Among the various commercial grade oil highest activity was observed with coconut oil 8.1 Uml-1 and gingili oil 6.8 Uml-1. Amino acids are also play a significant role for the lipase production. The maximum lipase activity was observed with glycine 5.1Uml-1 followed by tryptophan 4.6Uml-1 as a supplement. The organism grows optimally in the temperature of 40oC and pH 8. The strain isolated from the municipal sewage is industrially important from in terms of ability. These findings will be helpful in prospect for increase the production of industrial enzyme.
Hypotheses Testing on a Multivariate Null Intercept Errors-in-Variables Model

Considering the Wald, score, and likelihood ratio asymptotic test statistics, we analyze a multivariate null intercept errors-in-variables regression model, where the explanatory and the response variables are subject to measurement errors, and a possible structure of dependency between the measurements taken within the same individual are incorporated, representing a longitudinal structure. This model was proposed by Aoki et al. (2003b) and analyzed under the bayesian approach. In this article, considering the classical approach, we analyze asymptotic test statistics and present a simulation study to compare the behavior of the three test statistics for different sample sizes, parameter values and nominal levels of the test. Also, closed form expressions for the score function and the Fisher information matrix are presented. We consider two real numerical illustrations, the odontological data set from Hadgu and Koch (1999), and a quality control data set.

Integrated utilization of guava (Psidium guajava L.): antioxidant activity of phenolic extracts obtained from guava seeds with supercritical CO2-ethanol

In this work, it was explored the possibility of obtaining phenolic extracts with antioxidant activity (AA) from Colombian guava seeds (Psidium guajava L.) using supercritical carbon dioxide adding ethanol as cosolvent (SC CO2/EtOH). The crude extracts were obtained by block extraction designs step to step (four steps) as function of pressure (10, 15 and 20 MPa) and temperature (313, 323 and 333 K) (with four different extraction step designs). In each one of the extracts, the total phenolic content (TPC) and AA were determined (β-carotene bleaching and scavenging DPPH (2,2-diphenyl-1-picrylhydrazyl) methods). This work allowed to obtain a most effective phenolic extract, that presented a most potent antioxidant activity compared toward previous works. The most active extract was subjected to flash chromatography column (FCC), whose process was monitored by thin layer chromatography (TLC), being obtained four fractions. The most active fraction and the best crude extract were tested as potential antioxidant in edible oil (the response variables were the peroxide value (PV) and the conjugated dienes (CD)). It was observed that the fraction IV showed a good performance in preventing the formation of peroxides, while the best crude extract inhibited the degradation of conjugated dienes. The guava seeds are a promising source of antioxidants which can be extracted using SC CO2/EtOH by special extraction step design, these compounds can be used as preservatives in foods such as edible oils.
Haematological Changes in Predialyzed and Hemodialyzed Chronic Kidney Disease patients in Libya

Chronic kidney disease (CKD) is an emerging public health problem worldwide, with increasing cost of healthcare particularly in third world nations like Libya. Hematological parameters are generally influenced in CKD and the effect increases with the stage of CKD. Hematological profiles are rarely investigated in CKD subjects in our population.This study was conducted to determine the hematologic profile in Libyan CKD subjects and to compare it in both hemodialyzed and pre-dialyzed patients. The study included 55 hemodialyzed CKD patients, 50 pre-dialyzed CKD patients, and 48 healthy controls. Blood Samples were analyzed for urea, creatinine, and complete blood counts including hemoglobin concentration, red blood cells (RBCs), white blood cells (WBCs) and platelets count. The data were statistically analyzed using SPSS. Our results revealed that hypertension was the most common cause of CKD among the studied group. A significantly lower (p< 0.05) RBCs count, hemoglobin levels, and hematocrit in CKD patients than healthy controls. Platelet count was lower (p< 0.05) in hemodialyzed CKD patients than pre-dialyzed CKD subjects. have been shown in WBC count showed no significant change in CKD patients compared to control. The prevalence of anemia among hemodialyzed-CKD was markedly high (96% and 100% for males and females respectively) and double that of the predialyzed CKD patients (53% and 52% for males and females respectively). Estimated glomerular filtration rate showed a significant positive correlation with hemoglobin (Hb) concentration but non-significant correlations with other hematological parameters. These hematological abnormalities expose CKD patients to higher risk of anemia-related complications and bleeding disorders, and the risk increase with the stage of CKD. which may have a role in increasing the rate of patient mortality and morbidity. Moreover, hypertension as the most common cause of CKD in our study, this may indicate the lack management programs for blood pressure in hypertensive patients.
An effcient approximation of Q(√x) function and general BER performance analysis

In this paper, a novel approximation for the Gaussian Q-function in the form of Q(√x) is presented. The proposed approximation is compared with other known closed-form approximations of the Q-function in terms of accuracy and applicability. This approximation can be effciently used to simplify intractable problems which do not have explicit solutions. The approximation of the generalized probability density function (PDF) using Gaussian fnite mixture components is utilized with the proposed approximation to derive a generalized closed-form expression for the Bit Error Rate (BER) for coherent modulation techniques. The derived expression is evaluated over Nakagami-m and Weibull fading channels. Monte Carlo simulation of the average BER expression is provided over Nakagami-m and Weibull fading channels in order to validate the derived expression. The derived average SER expression can be used by engineers to evaluate the BER performance for any coherent modulation technique and over any fading channel given that the fading channel statistics are modeled using Gaussian fnite mixture.
Effects of arsenic on growth , photosynthesis and some antioxidant parameters of Panax notoginseng growing in shaded conditions

Article Type: Full Length Research Article This study assessed the effect of soil Arsenic (As) on growth height, leaf area, biomass, relative growth rate (RGR), photosynthetic activities [net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), inter-cellular CO2 concentration (Ci)] and selected antioxidant parameters [superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD)] of Panax notoginseng (Burk.) F. H. Chen. Two-years old plants in part-shade were subjected to As treatments, which were applied by supplementing soil with As to a final concentration of 20, 80, 140, 200 and 260 mg kg -1 with supplementary Na3AsO4•12H2O. The results obtained shows that total biomass, contents of total chlorophyll (Chl), Chl A and Chl B increased at low (20 mg kg -1 ) As concentration; but declined at higher (80-260 mg kg -1 ) As concentrations. The Chl A/B ratio, carotenoid content and ratio of root biomass to shoot biomass decreased in all As treatments. Pn had a 1.40-1.49 fold increase with As concentrations from 0 to 140 mg·kg -1 . Tr, Gs and stomatal limitation value increased significantly, whereas the inter-cellular CO2 concentration and water use efficiency declined under As stress. Leaf SP content, relative electrical conductivity and activities of SOD, CAT and POD increased under As stress. These results indicate that stomatal limitation value should be the most important factor responsible for Pn decline under As stress. The sensitive markers of P. notoginseng under As stress include growth characteristics (leaf area, RGR, biomass) and antioxidant parameters (relative electrical conductivity, SOD activity). ©2016 BluePen Journals Ltd.

Estimating the Probabilities of Runs of Identical Events Within Biological Sequences

Miyamoto and Fitch (1995) recently compared the properties and predictive powers of the covarion hypothesis (Fitch and Ayala 1994) with those of the gamma version of the one-parameter model (Ota and Nei 1994; Yang 1996). Miyamoto and Fitch focused on the degree to which the identities of polymorphic and monomorphic codons for the amino acid sequences of Cu, Zn superoxide dismutase (SOD, EC 1.15.1.1) were the same in mammals and plants, because less overlap (fewer positions being varied in both groups) is predicted between taxa by the covarion process than by the gamma model. Their comparisons relied on both computer simulations of sequence change and spatial analyses of amino acid replacements on the three-dimensional configuration of the protein. The latter analyses of amino acid replacements relative to tertiary structure included an evaluation of a run of eight consecutive varied positions that were polymorphic in plants but not in mammals. These eight sites from the first b-strand and loop at the Nterminus of the protein constituted the longest run of consecutive polymorphic positions, varied in that group only. Thus, Miyamoto and Fitch (1995) attempted to calculate the probability (P) of obtaining a run of eight or more polymorphic sites, restricted to either mammals or plants and anywhere among the varied positions, by their equation (5):
Biodegradation of spent engine oil by bacteria isolated from the rhizosphere of legumes grown in contaminated soil

Biodegradation of spent engine oil (SEO) by bacteria isolated from the rhizosphere of Cajan cajan and Lablab purpureus was investigated. It was with a view to determining most efficient bacterial species that could degrade SEO in phytoremediation studies. Hydrocarbon degrading bacteria were isolated and identified by enrichment culture technique using oil agar supplemented with 0.1% v/v SEO. Total heterotrophic and oil utilizing bacterial count showed the occurrence of large number of bacteria predominantly in the rhizosphere soil, ranging between 54×10 8 - 144×10 8 CFU/g and 4×10 8 - 96×10 8 CFU/g respectively. Percentage of oil utilizing bacteria ranged between 0% (uncontaminated non rhizosphere soil) to 76% (contaminated rhizosphere). Turbidimetrically, five bacterial species namely Pseudomonas putrefacience CR33, Klebsiella pneumonia CR23, Pseudomonas alcaligenes LR14, Klebsiella aerogenes CR21, and Bacillus coagulans CR31 were shown to grow maximally and degraded the oil at the rate of 68%, 62%, 59%, 58%and 45% respectively. Chromatographic analysis using GC-MS showed the presence of lower molecular weight hydrocarbons in the residual oil (indicating degradation) after 21 days, whereas the undegraded oil (control) had higher molecular weight hydrocarbons after the same period. The species isolated were shown to have high ability of SEO biodegradation and therefore could be important tools in ameliorating SEO contaminated soil.

Behavior of bulk high-temperature superconductors of finite thickness subjected to crossed magnetic fields: Experiment and model

Crossed-magnetic-field effects on bulk high-temperature superconductors have been studied both experimentally and numerically. The sample geometry investigated involves finite-size effects along both (crossed-)magnetic-field directions. The experiments were carried out on bulk melt-processed Y-Ba-Cu-O single domains that had been premagnetized with the applied field parallel to their shortest direction (i.e., the $c$ axis) and then subjected to several cycles of the application of a transverse magnetic field parallel to the sample $ab$ plane. The magnetic properties were measured using orthogonal pickup coils, a Hall probe placed against the sample surface, and magneto-optical imaging. We show that all principal features of the experimental data can be reproduced qualitatively using a two-dimensional finite-element numerical model based on an $E\text{\ensuremath{-}}J$ power law and in which the current density flows perpendicularly to the plane within which the two components of magnetic field are varied. The results of this study suggest that the suppression of the magnetic moment under the action of a transverse field can be predicted successfully by ignoring the existence of flux-free configurations or flux-cutting effects. These investigations show that the observed decay in magnetization results from the intricate modification of current distribution within the sample cross section. The current amplitude is altered significantly only if a field-dependent critical current density ${J}_{\mathrm{c}}(B)$ is assumed. Our model is shown to be quite appropriate to describe the cross-flow effects in bulk superconductors. It is also shown that this model does not predict any saturation of the magnetic induction, even after a large number $(\ensuremath{\sim}100)$ of transverse field cycles. These features are shown to be consistent with the experimental data.
