Authors: Olatunji Abdulkadir, Abdulkarim , Abubakar Gulma, Khadijah , Soye Mohammed, Alhaji 
Published: October 2018

This study investigated the relationship between parental expectation, attitude to academic subjects and career aspiration among senior secondary school students in Sokoto Metropolis. A descriptive research design was adopted in this study. Purposive sampling procedure was used to select 10 out of the 21 Senior Secondary Schools in Sokoto Metropolis. 346 students were selected using Research Advisor table of determining sample size in a given population. Three instruments were used for data collection in this study namely: Adopted Version of Boyi Parental Influence Questionnaire to measure parental expectations on career aspirations of students, Adopted Version of Boyi Subject Selection Questionnaire to measure students’ Attitude to Academic Subjects and Adapted version of Bakare Motivation for Occupation Preference Scale (MOPS) to measure students’ career aspirations. Data were analyzed using Pearson Product Moment Correlation and Multiple Regression Analysis with the use of Statistical Package for Social Science (SPSS) version 20.0. The result showed that there was significant relationship between parental expectations and career aspirations of respondents. Also there was significant relationship between attitude to academic subjects and career aspirations of respondents. However, it was found that attitude to academic subjects is more related to career aspirations of senior secondary school students than their parental expectation. Based on these findings, it was recommended that counsellors and teachers should assist the students in developing positive attitude to academic subjects in order to improve their awareness of career aspirations and to minimize the level of ignorance while choosing career.

Zusammenfassung
Ziel des vorliegenden ersten Teils dieser Untersuchung war, unter definierten Bedingungen die Entstehung und weitere Entwicklung akzessorischer Bursen an den Gliedmaßen von Mastschweinen zu erfassen. Material und Methoden: 192 Masthybriden wurden von der Aufzucht bis zur Schlachtung unter konventionellen Haltungsbedingungen untersucht. Wöchentlich wurden die Parameter Allgemeinbefinden, Anzahl, Größe und Lokalisation der akzessorischen Bursen an Gliedmaßen und Sternum sowie Gang und Klauen erfasst. Ergebnisse: Akzessorische Bursen können an bis zu 13 Stellen an den Gliedmaßen bzw. dem Sternum auftreten. Es wurden bereits Ferkel mit akzessorischen Bursen in die Aufzucht eingestallt, die Prävalenz stieg während Aufzucht und Mast an und lag vor der Schlachtung bei 97,8 % der Tiere (Einstallung mit 4 Wochen: 25,5 %; Umstallung in die Mast mit 12 Wochen: 67,6 %). Schwere Tiere wiesen signifikant mehr und größere Bursen auf als gleichaltrige leichtere Tiere. Außerdem nahmen sie größere Futtermengen auf, riefen aber weniger häufig Futter ab. Tiere mit stärkeren Gangbildveränderungen zeigten signifikant mehr und größere Bursen. Am Schlachthof bestand bei 95,6 % der Tiere mindestens eine Klauenveränderung. Das Allgemeinbefinden wurde durch akzessorische Schleimbeutel nicht beeinträchtigt. Schlussfolgerung und klinische Relevanz: Eine Beeinträchtigung des Wohl-befindens hinsichtlich Schmerzempfinden durch akzessorische Bursen wird aufgrund der vorliegenden Ergebnisse und der Funktion als Schutzkissen nicht vermutet. Dennoch entstehen akzessorische Bursen in hoher Prävalenz und Anzahl pro Tier unter Einfluss verschiedener Faktoren erst im Laufe des Lebens und stellen eine Technopathie dar. Aufgrund der Exposition akzessorischer Bursen besteht das Risiko, dass diese sich infolge von Verletzungen zu eröffneten Grad-3-Bursen entwickeln.

başlıca nedeni sanat dünyasında iyi bir yer edinme kaygısıdır ve bu durum sergi
salonunun sanat çevresini belirleyen bir mekân olma amacıyla paralellik
gösterir. İzleyici için amaç ise bazen sosyal bir aktivite bazen popüler sanat
dünyasına dahil olma arzusu bazen de sanata olan ilgi olabilmektedir. Bu
bağlamda sergiler, sanatçı, yapıt, mekân, izleyici arasında bir köprü görevi
görür. Bu sergiler ilk aşamada sanatçıya kendisini ve yapıtlarını en iyi
şekilde tanıtma fırsatı sağlarken sergi salonuna, gerçekleştirilen etkinlikte
sergilenen eserleri iyi bir şekilde mekâna uyarlama ve kamusal sanat alanını
belirleme işlevini görme şansı tanır. İzleyiciye ise bir etkinliğe dahil
olmaktan dolayı memnuniyet, yeni bakış açıları kazanma ve sanat çevresine dahil

Рождаемость в республике Молдова: европейские тенденции и национальная специфика
Authors: Гагауз Ольга Евсеевна 
Published: October 2018

В настоящее время официальная статистика Республики Молдова, основываясь на данных о численности населения de jure (включая граждан, отсутствующих в стране 12 месяцев и более), дает заниженные оценки коэффициента суммарной рождаемости, что привело к отнесению страны к группе стран со сверхнизким уровнем рождаемости (lowest-low fertility).
На основе данных о численности населения de facto, а также результатов Переписи населения и жилищ 2014 г. анализируются уровень и основные тенденции в динамике рождаемости в разрезе условных и реальных поколений. Основная цель исследования – проследить, до какого уровня снизилась рождаемость в Республике Молдова и можно ли ее относить к странам с низкой или очень низкой рождаемостью (low fertility or lowest-low fertility).
Результаты исследования показывают, что трансформация рождаемости происходит согласно общей модели, характерной для большинства стран, завершивших или находящихся в процессе перехода рождаемости, однако характеризуется более низкими темпами. Для условных поколений рождаемость установилась на уровне 1,6-1,65 рождений на одну женщину, тогда как для реальных поколений, завершивших или находящихся на стадии завершения репродуктивного периода – на уровне 1,9-2,0 рождения. Даже для самых молодых поколений, достигших на момент переписи 35-летнего возраста (2014 г.), среднее число рожденных детей превысило значение 1,7. Несмотря на то, что в межпереписной период наблюдается сокращение среднего числа рождений к концу репродуктивного периода, среднее число рождений у женщин к 50-летнему возрасту составляет 2,1, а доля тех, кто не родил ни одного ребенка сохраняется на относительно низком уровне.
Основываясь на результатах исследования, автор делает вывод, что Республика Молдова не относится к странам с низкой или очень низкой рождаемостью (low fertility or lowest-low fertility), а сохранение более высокого уровня рождаемости по сравнению с другими странами определяется преобладанием сельских жителей в общей структуре населения.

Interstitial changes in the lungs could be caused by vast majority of diseases including tuberculosis, sarcoidosis, hypersensitive pneumonitis, metastatic injury of the lungs, etc. Differential diagnosis of pulmonary dissemination remains an urgent and challenging clinical task. This article is a review of published literature and presentation of a clinical case of a patient with interstitial lung disease. The case demonstrates diagnostic difficulties in identification the cause of interstitial lung injuries. Interstitial lung injury was incidentally found in this patient and initially was considered as disseminated pulmonary tuberculosis. In-depth diagnostic work-up including lung tissue biopsy allowed diagnosis of lymphoid interstitial pneumonia associated with common variable immune deficiency. This case demonstrates common misdiagnosis of pulmonary tuberculosis in a patient with interstitial lung injury.

Am. J. Respir. Crit. Care Med. 2017; 195 (9): 1253–1263. DOI: 10.1164/rccm.201703-0548STThe aim of this guideline is to provide clinical recommendation on the use of mechanical ventilation in adult patients with acute respiratory distress syndrome (ARDS).Methods. This guideline is based on systematic review and metaanalysis of available literature on the use of mechanical ventilation in adult patients with ARDS.Results. All patients with ARDS should be mechanically ventilated with the use of lower tidal volumes (4–8 ml/kg predicted bodyweight) and lower inspiratory pressures (plateau pressure, 30 cm H2O). In severe ARDS, the prone positioning for more than 12 h/d is strongly recommended. In patients with moderate to severe ARDS, routine use of high-frequency oscillatory ventilation is not recommended; a conditional recommendation has been developed for the use of higher positive end-expiratory pressure and recruitment maneuvers. CuОР – ently, there is not enough evidence for the use of extracorporeal membrane oxygenation in patients with severe ARDS.Conclusions. Practical recommendations on selected methods to coОР – ect ventilation disturbances in adult patients with ARDS have been developed. Clinicians involved in the management of patients with ARDS should use personalized approach to the treatment of these patients.

Authors: Bolotova E. V. , Dudnikova A. V. , Yavlyanskaya V. V. 
Published: October 2018

The aim of this study was to investigate body composition in patients with COPD using two methods, Quételet index and bioelectrical impedance analysis (BIA), and to compare their diagnostic values.Methods. The study included 198 patients with COPD admitted to the Territorial Teaching hospital No.2, and 28 healthy volunteers. According to COPD severity, patients were divided into 4 groups; healthy volunteers (n = 28) were included in the control group. All groups were matched for sex and age. Anthropometry with body mass index (BMI) calculation and BIA were done in all participants.Results. The lowest average BMI was found in patients with severe and very severe COPD. Patients with infrequent exacerbations without decreased BMI had reduction in fat-free mass (FFM) in 12.3% (n = 25); 14.1% patients (n = 28) had increased body fat mass and decreased FFM. According to BIA results, reduction of FFM was seen significantly more often than reduction of BMI (57.6% vs 30%; χ2= 58.71; p = 0.03). BIA parameters describing muscle tissue were significantly related to the severity of bronchial obstruction (FEV1).Conclusion. Investigation of body composition using BIA method should be used as a tool for comprehensive examination of COPD patients, for personalized choice of treatment and in rehabilitation programs.
SOCIABILIDADES, TRABALHO SEXUAL E AUTONOMIA NO CONTEXTO DAS GRANDES OBRAS NA AMAZÔNIA BRASILEIRA
Authors: Araujo Wagner dos Reis Marques 
Published: October 2018

Neste texto apresento alguns dados parciais e reflexões teóricas referentes ao trabalho de campo que foi realizado durante os meses de junho de 2014 e novembro de 2015. Os dados foram coletados por meio de entrevistas em profundidade aplicadas a doze prostitutas em um contexto privilegiado pela observação direta e, também, pela abordagem etnográfica que foi realizada nos locais de trabalho das mulheres. Objetivando preservar a identidade das entrevistadas, adoto nomes de flores para identificá-las neste texto. Na modalidade de trabalho sexual exercida nos bares de prostituição do contexto pesquisado, as prostitutas declararam ter encontrado na prostituição possibilidades de negociações e de ganhos econômicos inexistentes no mercado de trabalho formal. Por exemplo, flexibilidade em termos de jornadas de trabalho, possibilidades de ganhos econômicos (principalmente entre as mais jovens) e mobilidade social impossíveis de se alcançarem através de outras atividades profissionais relegadas às mulheres dos estratos sociais subalternizados do Brasil. A amostra analisada não corresponde ao número total de trabalhadoras sexuais entrevistadas na consecução da pesquisa de campo do doutorado em Sociologia, pela Universidade Federal do Rio Grande do Sul (UFRGS). Priorizei aqui a compreensão e, sobretudo, a visão que as entrevistadas compartilham em relação à referida atividade ser profissional, embora não seja regulamentada e apesar de não haver, no município de Porto Velho, mobilização de trabalhadoras sexuais em torno de coletivos políticos, as mulheres têm esse entendimento. Pode-se concluir que, em suas práticas, as trabalhadoras sexuais estabelecem relações personalistas (com seus clientes e dono/as de estabelecimentos) onde parece haver margens seguras para a oferta de serviços de natureza sexual e negociação de seus agenciamentos corporais.
Some Improvements on Relativistic Positioning Systems
Authors: Alfonso Màrius Josep Fullana i , Milán Diego Pascual Sáez , Córdoba Josep Vicent Arnau i , Colmenero Neus Puchades 
Published: October 2018

Abstract
We make some considerations about Relativistic Positioning Systems (RPS). Four satellites are needed to position a user. First of all we define the main concepts. Errors should be taken into account. Errors depend on the Jacobian transformation matrix. Its Jacobian is proportional to the tetrahedron volume whose vertexes are the four tips of the receiver-satellite unit vectors. If the four satellites are seen by the user on a circumference in the sky, then, the Jacobian and the tetrahedron volume vanish. The users we consider are spacecraft. Spacecraft to be positioned cannot be close to a null Jacobian satellites-user configuration. These regions have to be avoided choosing an appropriate set of four satellites which are not seen too close to the same circumference in the sky. Errors also increase as the user spacecraft separates from the emission satellite region, since the tetrahedron volume decreases.We propose a method to autonomously potion a user-spacecraft which can test our method. This positioning should be compared with those obtained by current methods. Finally, a proposal to position a user-spacecraft moving far from Earth, with suitable devices (autonomous), is presented.
The Triaxiality Role in the Spin-Orbit Dynamics of a Rigid Body
Authors: Cantero A. , Crespo F. , Ferrer S. 
Published: October 2018

Abstract
We study the roto-orbital dynamics of a uniform sphere and a triaxial body by means of a radial intermediary, which defines a 2-DOF Hamiltonian system. Our analysis is carried out by using variables referred to the total angular momentum. Its validity and applicability is assessed numerically by experiments comprising three different scenarios; analysis of the triaxiality, eccentricity and altitude. They show that there is a range of parameters and initial conditions for which the radial distance and the slow angles are estimated accurately, even after one orbital period. On the contrary, fast angles deteriorates as the triaxiality grows. We also include the study of the relative equilibria, finding constant radius solutions filling 4-D and lower dimensional tori. These families of relative equilibria include some of the classical ones reported in the literature and some new types. For a number of scenarios the relation between the triaxiality and the inclination connected with relative equilibria are given.

Authors: Khalique Chaudry Masood , Mhlanga Isaiah Elvis 
Published: October 2018

Abstract
In this paper we study a (2+1)-dimensional coupling system with the Korteweg-de Vries equation, which is associated with non-semisimple matrix Lie algebras. Its Lax-pair and bi-Hamiltonian formulation were obtained and presented in the literature. We utilize Lie symmetry analysis along with the (G′/G)–expansion method to obtain travelling wave solutions of this system. Furthermore, conservation laws are constructed using the multiplier method.
Galerkin-Chebyshev Pseudo Spectral Method and a Split Step New Approach for a Class of Two dimensional Semi-linear Parabolic Equations of Second Order
Authors: Talay Akyildiz F. , Vajravelu K. 
Published: October 2018

Abstract
In this paper, we use a time splitting method with higher-order accuracy for the solutions (in space variables) of a class of two-dimensional semi-linear parabolic equations. Galerkin-Chebyshev pseudo spectral method is used for discretization of the spatial derivatives, and implicit Euler method is used for temporal discretization. In addition, we use this novel method to solve the well-known semi-linear Poisson-Boltzmann (PB) model equation and obtain solutions with higher-order accuracy. Furthermore, we compare the results obtained by our method for the semi-linear parabolic equation with the available analytical results in the literature for some special cases, and found excellent agreement. Furthermore, our new technique is also applicable for three-dimensional problems.

Acousto-optic modulation in ion implanted semiconductor plasmas having SDDC
Authors: Malviya P.S. , Yadav N. , Ghosh S. 
Published: October 2018

Abstract
The present paper is aimed to the exploration of acousto-optic (AO) modulational amplification in ion implanted semiconductors. The AO modulational process has been treated as a four wave parametric mixing process and the effective third-order acousto-optic susceptibility characterizing the instability process has been deduced. By considering that the origin of modulational interaction lies in the third order AO susceptibility arising from the nonlinear induced current density and using the coupled mode theory, an analytical investigation of an intense laser beam in a strain dependent dielectric constant (SDDC) semiconductor crystal is presented. We found a significant change in threshold and gain characteristics with changes in charge imbalance parameter. The presence of colloidal grains (CGs) plays an effective role in changing the threshold intensity and effective gain constant.

Published: October 2018

Este estudio analiza el impacto que tiene la estrategia de simulación en el desarrollo de la autodirección en alumnos de educación secundaria. Se realizaron recorridos virtuales a museos utilizando un objeto de aprendizaje, donde cada estudiante diseña y selecciona los puntos de su ruta. Cada recorrido considera los conocimientos previos del alumno considerando los elementos de la autodirección: cómo planifica y organiza, cuál es su manejo de las emociones y cómo reconoce sus habilidades para propiciar la mejora continua. Los resultados obtenidos, cuantitativos y cualitativos, permiten dar cuenta del efecto positivo que tiene este tipo de actividades en la autodirección, específicamente en la elaboración de sus propias estrategias de aprendizaje.
