Cutaneous circulation during dehydration and heat stress

Resting subjects were exposed for 12 hr to 43 C dry bulb, 28 C wet bulb, with and without rehydration. During dehydration, average weighted cutaneous opacity pulse amplitudes decreased 19.5%. An apparent relationship between calculated stroke volume and cutaneous pulse amplitudes existed. A 26% increase in heart rate offset decreases in perfusion per beat and probably contributed to a rise in diastolic pressure. Increases in skin temperature paralleled those of oral temperatures. In most subjects evaporative rates were slightly lower during dehydration. Certain dehydrating subjects maintained sweat rates at control levels but this did not prevent an increase in both oral and skin temperatures. Failure of temperature regulation in these experiments does not appear to be due to a decrease in heat transport or evaporation but rather to a lack of responsiveness of the sudomotor and vasomotor systems to increases in body temperature. Reasons for the temperature rise appear complex. evaporative weight loss; heat transport; skin temperature; temperature regulation Submitted on July 22, 1964
Chronic Fatigue Syndrome

Weariness is a typical manifestation in the populace, and there are no symptomatic tests for CFS. It is along these lines an analysis of prohibition and the rundown of potential differential judgments is wide, from exhaustion related with proceeding with effort through to that related with clinical as well as mental ailment. Consequently, an exhaustive and thorough appraisal including a physical and psychological wellness assessment should be completed [1]. It is especially critical to satisfactorily survey the danger of self-destruction. As patients with CFS can discover long arrangements troublesome, consider giving rest breaks during appraisals.
Association of Radiation Doses and Cancer Risks from CT Pulmonary Angiography Examinations in Relation to Body Effective Diameter

This study aims to evaluate the patient’s dose exposure from Computed Tomography Pulmonary Angiography (CTPA) examination and to estimates the cancer risk induced from the examinations based on the patient’s size. One hundred patients were recruited, and data information was collected retrospectively. A multi-detector (MDCT) (Philips Brilliance 128, USA) scanner were utilized for the CTPA examination, and dose data were obtained from the system. The effective diameter of each subjects’ image was measured for the Size-specific dose estimates (SSDEs). All subjects divided into Group 1 (19 – 25 cm), Group 2 (25-28 cm) and Group 3 (28-38 cm), where the association between gender were analysed. Effective dose (E), SSDE, organ dose and cancer risk of each group were evaluated and compared statistically using independent t-test and one-way ANOVA. The range of mean CTDIvol, DLP and E values were (6.44 – 17.42 mGy), (239 – 631 mGy), (5.19 – 13.90 mSv), respectively. In respective with the patient’s effective diameter, the mean SSDE value for Group 1, Group 2 and Group 3 were 9.93 ± 3.89 mGy, 13.70 ± 9.04 mGy and 22.29 ± 7.35 mGy. The organ dose and cancer risk attained for breast, lung and liver were 17.05 ± 10.40 mGy (194 per one million procedure), 17.55 ± 10.86 mGy (192 per one million procedure) and 15.04 ± 9.75 mGy (53 per one million procedure), respectively. Lung and breast with more massive patient’s effective diameter received the highest dose exposure which increases the probability of the cancer risk. CTDIvol was found to be underestimated, and SSDE provides more accurate in describing the radiation dose and cancer risk. Body effective diameter found to be significant on the estimation except for gender. Therefore, it is essential to apply optimised protocols in order to reduce patient’s exposure during CTPA examination.
Fiscal deficit and trade deficit nexus in Pakistan: An econometric inquiry

This study is an attempt to explore the short-term and long-term effects of the fiscal deficit along with other macroeconomic variables on the deteriorating trade deficit of Pakistan from 1980 to 2018 by using time series estimation techniques. The result of the autoregressive distributed lag (ARDL) bounds testing approach and error correction term revealed the existence of cointegration among variables of interest. The estimated long-run and short-run results of the ARDL approach showed a significant positive effect of fiscal deficit on Pakistan's trade deficit in the short-run, whereas a significant adverse effect is observed in the long-run. The findings validated the twin deficit hypothesis in the short-run, whereas twin divergence proposition is observed in the long run. The study suggests prudent fiscal and monetary policies to make macroeconomic conditions favorable for the development and competitiveness of domestic production sectors engaged in the international trade.

The ion pair NaHPO 4 - appears to have significant concentrations in physiological fluids.
Coronavirus COVID-19 Detection, Symptoms, Spread and Prevention

An ongoing outbreak of pneumonia associated with 2019 novel coronavirus (2019nCoV) was reported in China. The epidemiological evidence has shown a potential transmission of the 2019-nCoV during the incubation period. It is unclear if the infectivity exists during the incubation period, although a person-to-person transmission has been reported in previous studies. It was believed that 2019-nCoV was transmitted through respiratory tract and then induced pneumonia, thus molecular diagnosis based on oral swabs was used for confirmation of this disease. Likewise, patient will be released upon two times of negative detection from oral swabs. This review provides a cautionary warning that COVID-19 may be shed through multiple routes.
Synthesis of reactive dye to impart mosquito repellency to nylon

Abstract Mosquito repellent textile materials are being increasingly in demand as a preventive measure to protect the consumers from mosquito-borne diseases like malaria, dengue, etc. Many of these agents are applied in post-colouration operation to the fabric. Although initially they show good repellency against mosquitoes, upon repeated washing cycles, this effect gets diminished considerably. In the present work, nylon fabric is imparted mosquito repellent finish in one, single operation of dyeing cum finishing. This approach is based on the modification of commonly used mosquito-repellent N,N-diethyl-m-toluamide (DEET) and synthesizing a reactive dye based on this important ingredient. A reactive dye was synthesized in order to impart mosquito repellency to the nylon 6 fabric, DEET was first subjected to nitration using Potassium nitrate and dichloromethane (DCM). This nitrated product was reduced in the presence of water: ethanol (30:70) and the amine, thus, produced was then condensed with 2, 4, 6-trichloro-1, 3, 5-triazine (cyanuric chloride) a reactive group. The resultant product was finally reacted with an amino group present in 6-Amino-2-naphthalenesulphonic acid (Bronner’s acid) to obtain Sodium6-((4-(diethylcarbamoyl)-2-methylphenyl) amino)-1, 3, 5-triazin-2-yl) amino) naphthalene-2-sulfonate (reactive dye). This reactive dye was then applied on nylon 6 fabric by covalent bonding to provide mosquito-repellent material. The chemical structures of the dye were characterized using FTIR and 1H-NMR spectroscopy. The melting point of the dye was characterized by Differential Scanning Calorimetry. The fastness properties of the dyed cum finished fabric were measured to evaluate the performance of the dye. Efficacy of mosquito repellency of the treated nylon 6 fabric was studied using standard methods. The nylon 6 fabric reacted with the mosquito-repellent dye and showed very good durable mosquito-repellent activity.
Molecular detection and evaluation of resistance of Mycoplasma Pneumoniae to macrolide (Erythromycin) due to mutation in the 23S rRNA gene among Iranian Patients with respiratory infections

Objective: Mycoplasma pneumoniae is a common cause of community-acquired pneumonia. The global increased resistance of M. pneumoniae strains to macrolide (ML) has become a worrisome health problem. The widespread use of these drugs has led to increased rate of reported ML-resistant M. pneumoniae (MRMP) throughout the world. Therefore, this study was aimed to evaluate the resistance of M. pneumoniae against erythromycin due to mutations in the 23S rRNA gene of patients with respiratory infections in Iran.Results: According to the findings of the present study, employing specific primers showed that 17 cases (17%) were positive for mycoplasma genus and 6 cases (6%) positive for M. pneumoniae species. Also, analysis of the sequence of 23S rRNA gene, revealed that one of the samples had mutations at positions A2431G and G2491A. Measuring the minimum inhibitory concentration (MIC), revealed that all samples positive for M. pneumoniae with 23S rRNA gene were sensitive to erythromycin, and no ML resistance was reported.
Etude par modélisation des nanoparticules formées par séparation de phase dans les verres dopés terres rares

Les fibres optiques dont on faconne la reponse spectrale incorporent des ions luminescents, des ions de terres rares (TR), dans des nanoparticules (NP) formees in situ dans un verre de silice par separation de phase. Cette ingenierie necessite de comprendre le lien entre la composition des NP et l’environnement des TR.En Dynamique Moleculaire, les potentiels interatomiques existants pechent a reproduire la separation de phase observee experimentalement. Le melange xMgO-(1-x)SiO2 presente un domaine ou coexistent deux phases mixtes, riche en Mg ou en Si. Une telle separation de phase ne se modelise qu’avec un potentiel interatomique prenant en compte la ionicite des liaisons, realise ici par l’ajustement des charges des Oxygene selon l’environnement local. Ce modele adaptatif, transferable, permet de suivre pour la 1ere fois la formation de NP amorphes de quelques nm. Mixtes et riches en Mg, elles se separent d’une matrice riche en Si.Le dopage TR (Er3+ ou Eu3+) montre que leur voisinage depend de la taille des NP les contenant : plus les NP sont grosses, plus les fractions de TR et de Mg augmentent. Ce voisinage riche en Mg permet a ces TR d’augmenter leur coordinence en Oxygene et elles n’ont plus besoin de s’agreger entre elles pour satisfaire cette tendance naturelle.Une simulation de l’etirage a chaud d’un verre de silice confirme l’existence d’une anisotropie dans la fibre optique, venant de l’orientation persistante des petits anneaux de silice, et se manifeste par une anisotropie elastique. Les effets que ces conditions extremes induisent sur les NP seront etudies ulterieurement.La mise en œuvre d'un modele de champ cristallin correlera les modifications de l'environnement des TR avec leur reponse spectrale.
Ensemble Model Based on NNAR and SVR for Predicting Influenza Incidences

Time is an important factor in today’s life as everything is somehow related to it. Citizen’s health plays an important role in the economic growth of a country. Disease prediction has become necessary because diseases which are air-borne, contagious, infectious, etc. are inherently dynamic and thereby making it more difficult for health officials to properly prepare for inevitable epidemics. Such a contagious disease is influenza which is a respiratory disease commonly known as flu and is caused by the influenza virus. Its symptoms can be mild to severe and can be deadly if not treated on time. To predict the influenza cases on the basis of historical data, we have proposed a novel model, which is an ensemble of Neural Network Autoregression (NNAR) and Support Vector Regression (SVR). The accuracy of the model is compared based on different error metrics such as root mean square, mean absolute error and autocorrelation function with lag 1. Compared to standard SVR, the proposed ensemble model has shown a decrease of 5.42% in root mean square error and 6.82% in mean absolute error.
Crystal structure of orthorhombic ε-Al4Cr

The crystal structure of the orthorhombic e-Al 4 Cr phase in the Al-Cr system was determined by single crystal X-ray structure analysis: space group Cmcm (No. 63), a = 12.521(1) A, b = 34.705(2) A, c = 20.223(1) A, V = 8787.7(9) A 3 , Pearson symbol oC584-20.48, Z = 8; M r = 2256, composition Al 56.23 Cr 14.21 , D x = 3.41 g/cm 3 ; F(000) = 8576, λ (MOKa) = 0.71069 A, μ = 4.510 mm -1 , room temperature, R = 0.068 for 2839 reflections, goodness of fit S = 1.084. There are 55 (13 Cr+42 Al) independent atoms in the unit cell, in which 12 Cr atoms and 28 Al atoms have icosahedral coordination. Interatomic distances cover the ranges of 2.570 A ∼ 2.646 A, 2.421 A ∼ 2.978 A, and 2.480 A ∼ 2.983 A, for Cr-Cr, Cr-Al and Al-Al atomic pairs, respectively. The crystalline phase appears obviously as a layered structure perpendicular to the a-axis. A typical aggregation of the icosahedral clusters in the structure of the e-Al 4 Cr phase has been pointed out.
An extension of the landweber regularization for a backward time fractional wave problem

In this paper, we investigate numerical methods for a backward problem of the time-fractional wave equation in bounded domains. We propose two fractional filter regularization methods, which can be regarded as an extension of the classical Landweber iteration for the time-fractional wave backward problem. The idea is first to transform the ill-posed backward problem into a weighted normal operator equation, then construct the regularization methods for the operator equation by introducing suitable fractional filters. Both a priori and a posteriori regularization parameter choice rules are investigated, together with an estimate for the smallest regularization parameter according to a discrepancy principle. Furthermore, an error analysis is carried out to derive the convergence rates of the regularized solutions generated by the proposed methods. The theoretical estimate shows that the proposed fractional regularizations efficiently overcome the well-known over-smoothing drawback caused by the classical regularizations. Some numerical examples are provided to confirm the theoretical results. In particular, our numerical tests demonstrate that the fractional regularization is actually more efficient than the classical methods for problems having low regularity.
High-Performance Human Resource Practices through the Lenses of the Ability–Motivation–Opportunity Taxonomy: A Multilevel Perspective

Background. In the recent past, many studies were devoted to the relationship between High-Performance Human Resource Practices and different types of employee outcomes. Through these studies, it has been shown that High-Performance Human Resource Practices are related to desirable employee outcomes and for this reason the interest in the topic has intensified. Yet the way in which High-Performance Human Resource Practices produce expected performance has not been explained in a satisfactory way. Research aims. The article aspires to analyze the concept of High-Performance Human Resource Practices (HPHRPs) through the lenses of Ability–Motivation–Opportunity (AMO) taxonomy, and to examine the interrelations between these categories of practices, as well as to discuss their impact on employee performance. Methodology. The article applies literature review in the HPHRPs and AMO literature focusing on its outcomes in terms of employee ability, motivation, and opportunity, while applying the idea of the internalization process of HR activities. Findings. HPHRPs were reviewed through the perspective of the AMO taxonomy. The extended view on relationships between HPHRPs is provided through the intended, actual and experienced internalization levels. JEL Codes: J24, M12.
The Immune Response in Gastrointestinal Stromal Tumors

Background: Gastrointestinal stromal tumors (GISTs) are the most frequent tumors with mesenchymal origin at the level of the digestive tract. Assessment of intratumoral immune cells can provide valuable prognostic information and may contribute to the development of targeted immune therapies for selected cases. Here in we evaluated the inflammatory infiltrate in gastrointestinal stromal tumors, the ratios between cytotoxic and helper T cells and their prognostic significance. Methods: We retrospectively analysed 25 cases of GISTs and extragastrointestinal stromal tumors (EGISTs). Immunohistochemical testing for CD3, CD4, CD8, CD20 and CD68 was performed to emphasize the immune cells. Inflammatory cells were quantified with the help of ImageJ software. Statistical analysis was performed to search for correlation between the immune response and clinical-pathological and prognostic variables. Results: GISTs were in all cases infiltrated with immune cells in variable amount. The pattern of distribution was diffuse or in aggregates, most frequent around blood vessels. Gastric tumors had the largest amount of inflammatory infiltrate and EGISTs the lowest. The dominant intratumoral immune cells were represented by lymphocytes, with fewer plasma cells, histiocytes, eosinophils, neutrophils and mast cells. CD3+ lymphocytes were the most common subtype. In 9 cases the CD8+/CD4+ ratio was subunitary. An increased number of histiocytes were associated with a high risk of disease progression. No other correlation between immune cells and other prognostic factors were established. Conclusion: Gastrointestinal stromal tumors represent the site of complex interactions between various types of immune cells and neoplastic cells. Accumulation of CD68+ cells correlates with high risk GISTs. Our paper provides an overview on the inflammation in this tumor type and further studies are necessary for more comprehensive results.
Developing a sense of certainty

In a noisy world filled with confusion, humans need a toolkit of skills to help discern fact from fiction. In this dissertation, I explore one such tool and its development in childhood: metacognitive reasoning about confidence. In 7 studies, I investigate how children reason about the strength of subjective information, uncovering the properties of childhood metacognition and using its development as a tool to learn about metacognition more broadly. Fueling this research are two families of theoretical accounts: one which conceptualizes confidence as a direct readout of decision noise (Direct accounts), and one where confidence is a combination of information from multiple sources (Inferential accounts). These two accounts make divergent predictions about two properties of metacognition: (1) how tightly bound confidence is to the underlying decisions it evaluates, and (2) how broadly is confidence represented in the mind. I investigate these questions using a developmental lens for testing between these theories. These studies present a force-choice method of measuring children’s sensitivity to confidence by asking how closely they can tell apart two states of confidence. This method of assessing confidence allows me to narrow in on the properties of metacognition that develop independently of children’s overconfidence biases and developing linguistic knowledge. In Chapter 2, I use this measure to look for developmental change associated with confidence judgments when controlling for decision noise, finding age-related change consistent with the Inferential accounts. In Chapter 3, I test whether children reason about confidence using encapsulated systems or a broader metacognitive system, and probe whether these judgments share a unit of representation, finding evidence for both within the domain of perceptual judgments as predicted again by Inferential accounts. In Chapter 4, I investigate whether confidence is processed so broadly as to include reasoning about others’ abilities, but do not find strong evidence of this, suggesting a limit on the generality of confidence processing. All together, this dissertation shows that far from being subject to the whims of others, children possess a sense of confidence that combines multiple sources in information to create broadly-usable assessments of truth in the world.
Suplementos para terminação de ovinos em pastos de Brachiaria brizantha cv. Marandu

The objective was to evaluate the supplementation on the productive response, nutritional parameters and the cost of production of sheep grazing grass Marandu. The experiment lasted 84 days and 20 lambs were used with age and initial body weight of 21.73 kg and four months, as well four rumen fitted sheep of 12 months and 55.00 kg of body weight, divided into four paddocks of 0.1 ha provided, with water and supplements dispenser, to evaluated the following treatments: mineral mix, soybean meal, soybean seed and cottonseed whole. For the average daily gain observed were of 0.061, 0.080, 0.060 and 0.080 kg day-1, respectively, for the mineral mix, soybean meal, soybean seed and cottonseed whole. The average pH values were 6.16, 6.18, 6.25 and 6.23, respectively, for the mineral supplements, soybean meal, soybean seed and cottonseed whole, and values for rumen ammonia nitrogen were 11, 10, 24.77, 22.31 and 29.37 mg dL-1 of rumen fluid, respectively. Supplements of soybean meal and cottonseed whole increased weight gain at 8.75% compared to animals maintained only with mineral salt, however, the mineral salt produced weight gain with lower cost.
