Cardiovascular system is adapted to gravity, and reactions to its vanishing in space are presumably dependent on body size. Dependency of hematological parameters and body fluids reaction to simulated microgravity have never been studied as an allometric function before. Thus we estimated RBC, blood and extracellular fluid volumes in hindlimb-unloaded (HLU) or control (ATT) mice, rats and rabbits.RBC decrease was found to be size-independent, and the allometric dependency for red blood loss in HLU and ATT animals shared a common power (−0.054±0.008) but differrent Y0 (8.66±0.40 and 10.73±0.49 correspondingly, p&lt;0.05). Blood volume in HLU animals was unchanged compared to controls disregarding the body size. The allometric dependencies for interstitial fluid volume in HLU and ATT mice shared Y0 (1.02±0.09) but had different powers N (0.708±0.017 and 0.648±0.016 correspondingly, p&lt;0.05), indicating that interstitial fluid volume increase during hindlimb unloading is more pronounced in larger animals.Our data underscore the importance of size-independent mechanisms of cardiovascular adaptation to weightlessness. Despite use of mice hampers application of a straightforward translational approach, this species is useful for gravitational biology as a tool to investigate size-independent mechanisms of mammalian adaptation to microgravity.

Abstract. Elevated hydrogen sulfide (H2S) levels have been observed from open-air dairy manure storages that contain gypsum bedding. Gypsum (calcium sulfate), recycled from construction waste and manufacturing defects, provides a cost-effective bedding alternative for dairy cows. Gypsum bedding is reported to control moisture and bacteria in the stalls and can improve soil structure when land-applied. However, gypsum increases H2S production in the anaerobic environment of deep manure storages, which is released in dangerous concentrations when the manure is agitated. This study was undertaken to quantify and compare the H2S concentrations during agitation of manure storages for three dairy stall management categories: farms that use (1) traditional organic bedding, (2) gypsum bedding, and (3) gypsum bedding followed by a treatment added to the manure storage thought to reduce H2S emissions. Three farms used Vital Breakdown (manufactured by Homestead Nutrition, New Holland, Pa.), and one farm used OK-1000 (Pro Ag Solutions, Hawkins, Tex.). Nineteen agitation events at ten farms were monitored during spring and fall hauling seasons. Portable monitoring instruments recorded H2S concentrations around the perimeter of the manure storages prior to and during agitation. Results show that manure storage agitation at farms that use gypsum bedding produced H2S concentrations that were considered immediately dangerous to life and health (above 100 ppm). Increasing gypsum bedding use significantly increased cumulative H2S concentrations (p &lt; 0.0001). Farms that used Vital Breakdown as an amendment significantly reduced cumulative H2S concentrations when compared to farms not using a manure treatment (p &lt; 0.0001). Lower cumulative H2S concentrations at one farm were attributed to the OK-1000 manure treatment. Keywords: Cow, Dairy, Gas, Gypsum, Hydrogen sulfide, Manure, Safety.

Authors: Cruz Breno de Paula Andrade , Ross Steven Dutt 
Published: June 2018

Este ensaio discute 13 deslizes comuns encontrados em estudos no campo de Administração Pública e de Empresas no Brasil, agregando-os em três dimensões. A primeira dimensão, ‘Deslizes por Falta de Reflexão’ inclui deslizes por falta de reflexão dos autores, como, por exemplo, usar a palavra Metodologia na seção que discute Método ou autores economizarem em palavras para apresentar a relevância do trabalho. Já na segunda dimensão, ‘Deslizes na Utilização do Método’, discutimos aspectos referentes ao Método em um trabalho científico, deixando claro, por exemplo, alguns erros cometidos, tais como nomear um Método (Netnografia) e na prática usar outro (Observação Não-Participante). A terceira dimensão ‘Deslizes no Sentido de Fazer Ciência’, apresenta os deslizes relacionados à relevância de um texto ao se fazer Ciência. Por exemplo, um texto que não apresenta implicações gerenciais e teóricas no campo da Administração Pública e de Empresas ou que não discute questões para futuras pesquisas deixa a desejar no sentido de ser relevante para a Ciência e para as organizações.
Tanycytic Ependymoma of the Filum Terminale Region; a Case Report

Published: June 2018

Abstract
Tanycytic ependymoma is a very rare spindle-cell variant of ependymoma derived from tanycytes, which are part of the primitive nervous system. This paper is presenting 48-year old woman who presented with low back and right-sided leg pain of moderate intensity. MRI showed spinal intradural tumor at the level of the L1 vertebral body. Right-sided L1 hemilaminectomy and en bloc tumor resection were performed. Neuroradiological and intraoperative diagnosis of schwannoma was revised to tanycytic ependymoma after careful immunohistochemical analysis. Six months post-operativly, MRI did not show tumor recurrence. Tanycytic ependymoma at the region of filum terminale is extremely uncommon and only three cases have been described in the literature. The low incidence of this tumor and atypical histological image, which is distinct from the typical features of commonly encountered ependymomas, can present a challenge in terms of making an accurate diagnosis. Awareness of this transitional form of ependymoma among neurosurgeons and pathologists may avoid incorrect surgical approaches and postoperative treatment course.
A Mathematical Model Governing Tornado Dynamics: An Exact Solution of a Generalized Model
Authors: Pandey Sanjay Kumar , Maurya Jagdish Prasad 
Published: June 2018

Abstract
We investigate in this paper the dynamics of tornadoes by considering that the real inflow radial velocity depends on both the radial and vertical coordinates. The formulation is based on the model for the radial velocity that has been deduced from an experimentally verified model of azimuthal velocity. We present an analytical model for steady, incompressible, and viscous fluids and try for exact solutions. Although all the three components depend on radial and axial coordinates, viscosity affects merely the azimuthal velocity and the pressure. It is observed that the magnitude of the radial velocity increases to the maximum at the core but reverses the trend beyond and vanishes as it reaches the centerline. The magnitude reduces linearly with axial distance as per the supposition. At the core, the larger the Reynolds number, the lower is the velocity for moderate Reynolds numbers. Insignificant impact is observed for very large Reynolds number. However, inside and outside the core, the trends are reversed. Radial pressure distributions for different axial positions are similar to theoretical, numerical, and experimental observations. As we move outward from the axis, pressure increases. The difference between the pressures at the axis and that in outward regions increases with height. Pressure falls with rising Reynolds number uniformly for all radial distances. This is an indication that quantitative difference in pressure is large between viscous and inviscid flows.

1-(3′,5′-Anhydro-2′-deoxy-3′-thio-D-lyxo-furanosyl)thymine is prepared from the corresponding methyl pentofuranoside by using the silyl Hilbert–Johnson reaction. The α- and β-anomers are separated by column chromatography and their configuration is elucidated by NMR spectroscopy and, in case of the α-anomer, by an X-ray structure determination.
Work-Life-Balance und Arbeitsbedingungen von wissenschaftlichen Mitarbeiterinnen und Mitarbeitern in Deutschland
Authors: Lenkewitz Sven , Möhring Katja 
Published: June 2018

Abstract
Die Arbeitsbedingungen von wissenschaftlichen Mitarbeiterinnen und Mitarbeitern in Deutschland sind durch eine ambivalente Mischung aus hoher Autonomie und interessanten Arbeitsinhalten einerseits, unsicheren Arbeitsverhältnissen und unklaren Karriereaussichten andererseits geprägt. Wir analysieren die Einflussfaktoren der work-life balance in dieser Gruppe und beziehen sowohl den Konflikt von Arbeit und Privatleben (work-life conflict) als auch die wechselseitige Bereicherung (work-life enrichment) ein. Für die empirischen Analysen verwenden wir Daten einer Onlinebefragung von 96 wissenschaftlichen Mitarbeiterinnen und Mitarbeitern in den Sozial- und Wirtschaftswissenschaften einer deutschen Universität aus dem Jahr 2015. Mit linearen Regressionsanalysen untersuchen wir, wie Arbeitsbedingungen und -ressourcen work-life conflict und work-life enrichment beeinflussen. Zentrales Ergebnis unserer Analyse ist, dass insbesondere befristete Verträge und Wochenendarbeit den work-life conflict erhöhen. Eine gute Arbeitsatmosphäre im Team trägt hingegen zu einer Bereicherung des Privatlebens bei.

Abstract
Brito, CJ, Moreira, DG, Ferreira, JJ, Díaz-de-Durana, AL, Miarka, B, Bouzas Marins, JC, and Sillero-Quintana, M. Immune response related with skin thermal pattern in judokas: A new application for infrared thermography? J Strength Cond Res 34(10): 2886–2894, 2020—This study investigated the association between body skin temperature (BST) and immune response after judo training, and compared the immune responses considering 2 post-training skin thermal pattern (“spots”—SPT and “localized”—LOC). For this, we evaluated 32 (25-male) black-belt judokas from the Spanish Junior National Team (18.0 ± 3.5 years, 72.4 ± 18.4 kg, and 17.1 ± 7.5% body fat). White blood cell and BST measurements were performed at pre-training, immediately, 1, and 24-hour post-training. Body skin temperature (° C) was estimated by skin temperature from 4 regions of interest (chest, upper arm, thigh, and calf). The main results indicated that 13 judokas were classified as SPT and 19 as LOC. In comparison with LOC, SPT had a significantly lower BST post-training (SPT = 33.0 ± 0.4 vs. LOC = 33.6 ± 0.8° C; p = 0.016), lower blood concentration of leukocytes (SPT = 7.9 ± 1.9 vs. LOC = 8.9 ± 1.9 cells × 103 per mm3; p ≤ 0.001), and neutrophils (SPT = 5.5 ± 1.7 vs. LOC = 6.1 ± 2.2 cells × 103 per mm3; p ≤ 0.001). In conclusion, the BST and immune response after judo training seem to be not associated. However, when the skin thermal pattern is considered, the SPT skin thermal pattern presented a lower post-training BST, blood leukocytes, and neutrophils in comparison with the LOC group. These results show a possible relationship between skin thermal pattern and immune responses for the first time; however, further studies are needed to confirm the evidence presented here.
The Effect of Balancing Selection on Population Differentiation: A Study with HLA Genes
Authors: Brandt Débora Y C , César Jônatas , Goudet Jérôme , Meyer Diogo 
Published: June 2018

Abstract
Balancing selection is defined as a class of selective regimes that maintain polymorphism above what is expected under neutrality. Theory predicts that balancing selection reduces population differentiation, as measured by FST. However, balancing selection regimes in which different sets of alleles are maintained in different populations could increase population differentiation. To tackle the connection between balancing selection and population differentiation, we investigated population differentiation at the HLA genes, which constitute the most striking example of balancing selection in humans. We found that population differentiation of single nucleotide polymorphisms (SNPs) at the HLA genes is on average lower than that of SNPs in other genomic regions. We show that these results require using a computation that accounts for the dependence of FST on allele frequencies. However, in pairs of closely related populations, where genome-wide differentiation is low, differentiation at HLA is higher than in other genomic regions. Such increased population differentiation at HLA genes for recently diverged population pairs was reproduced in simulations of overdominant selection, as long as the fitness of the homozygotes differs between the diverging populations. The results give insight into a possible “divergent overdominance” mechanism for the nature of balancing selection on HLA genes across human populations.
Claro que vengo* a tu fiesta: La enseñanza de los verbos deícticos ir/venir y llevar/traer a estudiantes angloparlantes
Authors: Chui Daniel 
Published: June 2018

El presente estudio tiene como objetivo determinar si el enfoque pedagógico conocido como Processing Instruction (PI) (VanPatten 1996, 2002) es tan eficaz como el enfoque Meaning-Based Output Instruction (MOI) (Farley, 2001b) en la enseñanza de los patrones de uso de los verbos deícticos en español a hablantes nativos del inglés. Los verbos en cuestión son ir, venir, llevar y traer. Este trabajo pretende investigar en primer lugar si los hablantes nativos del inglés pueden aprender el sistema más restrictivo del castellano (Gathercole, 1978; Lewandowski, 2007). En el estudio, tres grupos fueron comparados: un grupo de control, uno de PI y otro de MOI. Cada grupo hizo una pre y post-prueba de interpretación y de producción. Los dos grupos de tratamiento recibieron instrucción entre pre y postprueba. La participación en cualquiera de los dos grupos de tratamiento fue positivamente correlacionada con un rendimiento superior en la prueba de interpretación, pero no en las pruebas de producción. En general, los resultados sugieren que, a pesar de que los participantes se beneficiaron de la instrucción en el experimento de interpretación, los estudiantes en el tercer trimestre del primer año de español no son capaces todavía de producir los verbos deícticos de manera diferente a su lengua materna.
Los estereotipos de los docentes en las clases de L2: Reflexiones en torno a una manera de enseñar español más sensible al género, al concepto de familia y a la niñez
Authors: Calvo Shadid Annette 
Published: June 2018

El artículo trata algunos estereotipos sociales que mantienen los profesores de español como segunda lengua, y también de otras lenguas, en cuanto a la mujer, el concepto de familia, y los valores que se transmiten a la niñez en la clase. El texto llama a la reflexión acerca de los propios estereotipos y de cómo existen textos, como los que aquí se presentan de Pippi Mediaslargas, de Astrid Lindgren, que ponen en tela de duda muchos de los conceptos establecidos acerca de la mujer, las niñas, las expectativas sociales y la familia, y se contrastan con modelos tradicionales como los que son representados en la mayoría de las películas de “Princesas de Disney”.

Személyiség, érzelmi intelligencia és élettel való elégedettség
Authors: Bányai-Nagy Henriett 
Published: June 2018

Elméleti háttér
A korábbi kutatások szignifikáns összefüggést jeleztek az érzelmi intelligencia és a jóllét különböző mutatói között. A kapcsolat erőssége nagymértékben változott annak függvényében, hogy az érzelmi intelligencia mérése milyen módszerrel történt, illetve egyelőre nem tisztázott, hogy az érzelmi intelligencia a Big Five faktorok kontrollálása mellett is a szubjektív jóllét szignifikáns magyarázótényezőjének tekinthető-e.

Cél
Jelen tanulmány a Big Five személyiségfaktorok, a vonás jellegű és képességalapú érzelmi intelligencia és az élettel való elégedettség összefüggéseit vizsgálja.

Módszerek
Keresztmetszeti kutatásunkban 421 fő vett részt (166 férfi és 255 nő). Az eljárás során az alábbi kérdőíveket töltötték ki a résztvevők: Érzelmek Mérése Skála (AES-HU), Érzelemszabályozás Szituációs Teszt (STEM), Ekman 60 Arc Teszt, Big Five Kérdőív (BFI), Élettel való Elégedettség Skála (SWLS).

Eredmények
Eredményeink szerint négy Big Five dimenzió (extaverzió, barátságosság, lelkiismeretesség, nyitottság) pozitív, a neuroticizmus pedig negatív korrelációt mutat mind az élettel való elégedettséggel (r = 0,20–0,33; p < 0,01), mind a vonás érzelmi intelligenciával (r = 0,21–0,55; p < 0,01). A hierarchikus lineáris regresszió elemzés eredményei szerint az extraverzió, a neuroticizmus és a vonás érzelmi intelligencia is szignifikáns önálló magyarázóerővel bír az élettel való elégedettség vonatkozásában. A vonás érzelmi intelligencia azután is szignifikáns hányadot magyaráz az SWLS pontszámok varianciájából miután kontrolláljuk a Big Five faktorokat (korrigált R2 = 0,231; F(7, 413) = 21,016; p < 0,001). Ezzel ellentétes módon a vizsgált képességalapú érzelmi intelligencia-mutatók függetlennek bizonyultak mind a személyiségtől, mind pedig az élettel való elégedettség szintjétől.

Következtetések
Az eredményeink egybecsengnek azokkal a korábbi kutatásokkal, amelyek igazolták, hogy a Big Five faktorok fontos szerepet játszanak az élettel való elégedettségben, illetve demonstrálták, hogy a vonás jellegű érzelmi intelligencia kapcsolatban áll a szubjektív jólléttel.

Authors: Aseri Gayatri , Agrawal Sudesh 
Published: June 2018

Background: This study was carried out to assess the knowledge, attitude, and practice of contraceptive methods among women attending a tertiary care hospital in Western Rajasthan.Methods: This cross-sectional study was conducted in the department of obstetrics and gynecology, PBM and the associated group of hospitals, attached to Sardar Patel Medical College, Bikaner, Rajasthan, India. Total 500 married women between age group 15-49 yrs were included. These all women interviewed using a structured questionnaire after approval of the hospital’s ethical committee.Results: Total 500 women interviewed for their knowledge, attitude, and practices about contraception. Out of which, 402 (80.4%) women had some knowledge of at least one contraception method at the time of the study. The most common sources of information about contraception were husband and family member. Amongst the various contraceptives most commonly known was condom (78.4%). Only 265 (53%) women were practicing contraception at present. Most commonly used contraceptive was condom (40.8%). The most common reason for the non-practice of contraception was need of more child or male child in 34.8% families followed by opposition from in-laws (12.4%).Conclusions: Literacy was positively associated with family planning related knowledge and practices. Preconception knowledge and practices about contraception are poor in our study population. Many of the women were getting MTP pills over the counter without consulting to health care persons and then later presents with complications.
