Formação em serviço social: articulação entre expressões da “questão social”, políticas sociais e território
Authors: Joazeiro Edna Maria Goulart , Mariosa Duarcides Ferreira 
Published: October 2016

O artigo, de maneira reflexiva, apoiado na bibliografia sobre o tema e na experiência docente no ensino superior, aponta para a diversidade de elementos que concorre para que, tanto no âmbito da formação, quanto na esfera da intervenção do Serviço Social, as vivências e experiências de estudantes estagiários em campo de estágio, sejam acompanhadas de uma leitura crítica com vistas à intervenção pertinente que busque, antes de tudo, compreender os nexos e os sentidos das relações sociais materializadas no território. A discussão é apresentada em três partes. No primeiro momento, discute-se o território como espaço de relações, portanto, além de seus limites puramente espaciais, naturais ou geográficos. Em seguida, aponta-se para alguns dos elementos contraditórios que emergem quando o território vivido separa ou é separado do território administrativo-legal. Por fim, discute-se como o processo da busca de compreensão do território impacta no processo de formação e, portanto, está intimamente relacionado ao processo de intervenção no campo do Serviço Social. Conclui-se afirmando que a complexidade que envolve a realidade social está presente de modo inelutável nas demandas da atualidade; e que esse encontro com fragilidades e potências explicitam as riquezas do processo formativo da e na profissão na contemporaneidade.
Políticas imigratórias: O nacional e o universal
Authors: Silva Ademir Alves da 
Published: October 2016

O presente texto apresenta o resultado de estudo preliminar sobre a questão das imigrações no contexto da crise capitalista contemporânea, a partir de matérias selecionadas de periódicos. São identificadas, nas pautas de movimentos e partidos ultraconservadores, variadas expressões de xenofobia, hostilidade e intolerância em relação aos imigrantes em vários países, evidenciando a contradição entre a desregulação e livre circulação de capitais e mercadorias e, por outro lado, as crescentes restrições ao deslocamento de pessoas. O estudo permitiu entrever nas atitudes de rejeição aos imigrantes as armadilhas ideológicas da conversão do diferente em inimigo − recobrindo interesses econômicos na exploração de mão de obra − sob o pretexto de incompatibilidades étnico-culturais supostamente ameaçadoras de “integridades nacionais”. Foi possível, portanto, identificar a tendência de transmutação da oposição entre trabalhadores nacionais e trabalhadores imigrantes − que serve aos interesses de redução dos custos de mão de obra −, em questões de preservação da ordem, segurança e identidade cultural. As reflexões permitiram reiterar, ao final, a importância de políticas públicas que, mediante mecanismos democráticos de regulação, assegurem a inserção e a participação dos trabalhadores imigrantes na vida social, cultural, política e econômica do país de destino, segundo princípios de convenções e tratados internacionais e sob critérios universalistas de justiça social.
Dinâmica migratória recente na RM de Campinas: Análise dos fatores associados
Authors: Dota Ednelson Mariano 
Published: October 2016

Os resultados em termos de organização socioespacial das grandes cidades tornam-se cada vez mais complexos de se analisar: novas variáveis começam a se destacar e a sociedade fluída do século XXI tem nos fluxos de população a possibilidade de novas escolhas locacionais, que impactam a forma e o direcionamento da expansão urbana. As regiões metropolitanas, neste sentido, são lócus dos movimentos de população, que representam fator imponderável com causas e motivações das mais diversas ordens, e que deve ser mais bem entendida para que se possa melhor compreender seus resultados socioespaciais. O presente trabalho analisa a dinâmica migratória recente da Região Metropolitana de Campinas a partir dos fatores associados, utilizando-se para isso dados do Censo Demográfico de 2010 e dois modelos de regressão logística binária para migrantes e “não-migrantes”, considerando as características sociodemográficas e as variáveis do contexto social. Observa-se, a partir de tal metodologia, migrantes com características bem definidas e uma estreita relação com as dinâmicas habitacionais e do mercado de trabalho, a partir da concentração espacial das oportunidades em âmbito regional.
L’alternance : avec un point de vue anthropologique sur le travail
Authors: Durrive Louis 
Published: October 2016

La conférence qui suit a été donnée devant les inspecteurs généraux (IGEN) de la « voie professionnelle » en France. Les IGEN sont les conseillers du ministre de l’éducation nationale pour les programmes scolaires. L’exposé veut montrer que, grâce à un point de vue anthropologique sur le travail (celui de l’ergologie), il est possible de réfléchir à l’alternance d’une manière très nouvelle. On appelle « alternance » le fait d’organiser la formation en partie dans une école et en partie dans une entreprise. L’objectif est de lutter contre l’échec scolaire, en montrant que l’expérience de l’école et l’expérience du travail ont un dénominateur commun : l’activité humaine. En s’appuyant sur l’activité de l’élève, on peut lui redonner le goût d’apprendre.
Parental involvement in career education and guidance in secondary education
Authors: Oomen Annemarie 
Published: October 2016

A European political focus on involving parents in education seeks to reduce the dropout rate, in order to improve the efficiency of the educational system. This is a valuable drive because the research literature suggests that parents are important influencers and advisers. Internationally, interventions have been designed to involve parents more in adolescents’ career development since the 1960s. These interventions can be arranged in three models: (a) career information-centred; (b) family learning; and (c) family therapy. Moving forwards, it is important to develop stronger models for parental engagement in career guidance, alongside an accompanying research agenda.
Leading Edge Developments in Ultrasonic Logging Improves Cement Evaluation Quality in Extreme Conditions

Published: October 2016

Abstract
Improvements in ultrasonic cement evaluation technology are increasing operational efficiency and reliability and extending the operating envelope into extreme environments with heavy muds and larger and thicker casings. Tool hardware, software, and firmware have been substantially redesigned and optimized to increase acquisition efficiency and data quality output. One key aspect is the complete redesign of various ultrasonic transducers to enable acquisition in the heaviest, highly attenuative muds. A specially designed transducer for thick casings and large rotating logging heads are pushing the thickness and diameter envelope to cover almost all possible scenarios.
Yard tests were conducted to emulate extreme downhole conditions in a controlled way: A casing filled with heavy mud (2-g/cm3 synthetic oil-based mud [SOBM]) and cemented in an eccentered position inside a simulated formation was tested with two complementary ultrasonic techniques, pulse-echo and flexural wave imaging. These tests demonstrated the proper performance of both measurements despite the highly attenuative logging mud and made it possible to determine annulus material impedance, casing centralization, and location of the position of a "simulated measurement cable" (such as fiber-optics bundles) cemented inside the annulus. Through two field tests we further confirmed the efficiency improvements concerning logging speed (i.e. software/firmware). Logs have been obtained in extremely heavy mud environments and 26.7-mm (1.05-in.) thickness casing.
These new developments in ultrasonic cased hole technology enable cement evaluation and pipe inspection in environments of the heaviest muds and casings of extremely large size and greater thickness, thus augmenting the industry's ability to diagnose well integrity while helping to reduce uncertainty and risk in well construction or before abandonment operations.
Petroleum Systems Modeling in Amudarya Basin
Authors: Ismagulova Saltanat , Abbasova Saidakhon , Karshiyev Odash 
Published: October 2016

Abstract
The present paper describes the results of petroleum systems modeling of Amudarya basin, which includes Bukhara and Chardzhou structural steps. The main purpose of the study is assessment of the quality of available data for the basin modeling, the description of the elements of petroleum systems, the history of source rock maturation and possible hydrocarbon migration routes, and recommendations for the required data.
There are two main source rocks in the Amudarya basin of Lower-Middle Jurassic and Upper Jurassic age, which correspond to type III and type II kerogen, respectively. The main reservoirs are carbonate structures of Oxfordian age and clastic rocks of the Cretaceous age. Caprock is a salt-anhydrite formation of Tithonian age, which acts as reliable regional seal.
As the result of the study, 1D models of Bukhara and Chardzhou steps and a 2D model through Gazli and Shurtan fields, showing the transformation ratio of kerogen and hydrocarbon migration routes, were obtained. Modeling was performed on petroleum systems modeling software. The results were calibrated with temperature and vitrinite reflectance data, where possible. The ability of the model to predict accumulations in the existing fields was tested.
The main elements of petroleum systems have good quality and the basin may contain up to 1.1 to 1.4 TCM of undiscovered gas. The authors believe that the potential of the Amudarya basin has not been exhausted, and there is the need for extensive and detailed basin modeling studies to identify the most perspective areas for further exploration.
The First Application of Wireline 3D Radial Probe for Determination of Permeability and Mobile Fluid Type in Highly Water Saturated Rocks in the Piltun-Astokhskoye Field
Authors: Kazakevich Eduard , Abram Peter , Wichers Wicher , Weinheber Peter , Makhmotov Akikat , Sakamoto Kazuho , El-Battawy Ahmed 
Published: October 2016

Abstract
The Piltun-Astokhskoye field is located off the east coast of Sakhalin Island and has been on production since 1999. Several layers of the reservoir rocks feature high water saturations in the range of 40 to 90%, particularly within the ‘deep layers’. A key uncertainty for the development is the productivity of these layers: how much of which fluid will flow and at what saturation level? This paper looks at the various options for reducing this uncertainty. Ultimately, a wireline formation tester option was chosen, and we cover the execution of the job and the interpretation of the acquired data.

Authors: Vasilev I. , Alekshakhin Y. , Kuropatkin G. 
Published: October 2016

Abstract
Naturally fractured reservoirs present a problematic type of oil and gas production target. It is not an exaggeration to say that big part of the world oil and gas reserves are concentrated in naturally fractured reservoirs (NFR).
Naturally fractured formations may have different genesis. Volcanic, metamorphic and sedimentary rocks undergo of fracturing and faulting as well while forming extensive and narrow system of highly conductive zones.
In this paper, we investigate and analyze core study results, drilling and completion in naturally fractured reservoirs; we demonstrate results of the well tests and interpret pressure build-up data. We draw conclusions about pressure transient behavior in naturally fractured formations and demonstrate a set of pressure build-up (PBU) drevative curves.
Application of Hydraulic Flow Units for History Matching of the Hydrodynamic Model of Tengiz Field
Authors: Kassenov Akzhan , Uzykanov Zhaslan 
Published: October 2016

Abstract
Tengiz field is one of the largest oil fields in the world. Reservoir is an isolated carbonate structure of a big area and big thickness. High heterogeneity caused by complex heterogenic and structural history of reservoir rises many uncertainties and makes characterization of reservoir extremely complicated. This fact alongside with big area and high hydrocarbon column of reservoir may make some of reservoir characterization techniques less effective. In this work was examined application of alternative Hydraulic Flow Units technique of distribution of permeability values for model. HFU technique divides reservoir to discrete units, which have lateral continuity and confirm lithological and facial heterogeneity of reservoir. This technique compared with classic porosity vs permeability correlations. Application of different permeability models were examined and compared through its effect on history matching of bottom hole pressures of Tengiz field simulation model. Additionally, was examined performance of two hydrodynamic simulators (E300 and Intersect) at conditions of big number of cells and high heterogeneity of reservoir.
A difficult airway in a child with Kaposi's Sarcoma of the epiglottis
Authors: Yip Elaine 
Published: October 2016

SummaryThe successful management of a difficult airway, whether anticipated or not, necessitates clinical expertise, adequate human resources, and appropriate equipment. The absence of any these key elements potentially exposes the patient to serious harm or even death. The emotion generated when dealing with such an emergency is often exacerbated in a paediatric patient. We present the case of a child with a difficult airway who presented to a low resource healthcare facility in rural South Africa. There was no available past medical history, the presenting diagnosis was unclear and there was a lack of specialist equipment. Despite these challenges anaesthetic management was successful. The unusual diagnosis of epiglottal Kaposi's sarcoma was made retrospectively at a tertiary centre.
Apnoeic oxygenation for glottic stenosis surgery
Authors: Falzon David , Ball D. R. 
Published: October 2016

SummaryAirway management for laryngeal carcinoma with glottic stenosis is challenging. Tracheal intubation may not be achievable and a variety of open airway techniques have been described with low or high frequency jet ventilation, as well as intermittent apnoea to allow an unrestricted view for surgery to proceed. Tracheostomy is another option [1]. We report successful use of apnoeic mass movement oxygenation by insufflation of oxygen via a narrow‐bore cricothyroid cannula, with intravenous general anaesthesia for laser reduction of laryngeal tumours in two adult patients. The technique described provides a completely open, still, operative field and avoids the need for tracheostomy.
High flow nasal apnoeic oxygenation in a high risk patient
Authors: Raffles Michael , Stolady Daniel , Pearson Darcy , Blunt Mark 
Published: October 2016

SummaryHigh flow nasal oxygenation uses the phenomenon of aventilatory mass flow to provide continuous oxygenation during the apnoeic period between induction of anaesthesia and tracheal intubation. It has been shown to significantly increase the time to desaturation in cases of difficult intubation. We describe a case of a lady with CREST syndrome (a variant of scleroderma) presenting for surgery. Her disease included gastro‐eosophageal reflux, a potentially difficult airway and poor left ventricular function. Neuraxial blockade was contraindicated due to coagulopathy and localised cellulitis over her lower back. High flow nasal oxygenation was employed during induction, allowing a slower more controlled induction whilst maintaining haemodynamic stability. We believe this to be a well‐tolerated, effective method of increasing apnoea times, giving more flexibility over speed of induction when the classical rapid sequence induction may result in unacceptable cardiovascular instability.

Published: October 2016

SummaryVasovagal syncope during central neuraxial blockade is a recognised phenomenon. We report a case of syncope, which was preceded by an increase in the amplitude of the plethysmograph trace. We review the physiological changes leading to such an episode and the role of plethysmographic pulse oximeter waveform variation monitoring in the prediction of syncope.
Return of spontaneous circulation confirmed by two dimensional ultrasound following pulseless electrical activity arrest
Authors: Miller Matthew , Grant Peter , Krishnaraj Murali 
Published: October 2016

SummaryWe report a case of Pulseless Electrical Activity (PEA) cardiac arrest following induction of anaesthesia where, in the absence of central pulses, the return of spontaneous circulation was confirmed by two‐dimensional ultrasound (2D US) and colour flow Doppler of the femoral artery. When cardiac arrest occurs in hospital confirmation of palpable pulses forms part of the assessment of the return of spontaneous circulation and is a guide to subsequent therapeutic decisions. However difficulties in identifying central pulses during cardiopulmonary resuscitation are well documented. With the increasing availability and familiarity of 2D US, this modality may provide an option for assessment of quality of cardiopulmonary resuscitation and the return of spontaneous circulation.

Death, the foreigner who strikes fear in every manDeath, the shadow who lingers over every man‘I know not thee,’ I saidUnaware of its power‘I am your end,’ it said,‘Waiting for you in the pyre,’ The fear struck me and stayed with me forever. I refused to believe and heard him scorn.‘Go away,’ I said,Refusing to accompany him.‘I am you and you are me,’ he said.Forcing me to believe in him. They told me Death is an ultimate end,Everyone faces him, heIs a mystery they said, unknownTo even those who believe in him.

Authors: Ríos M. Diana Katherine , Viteri R. Silvio Edgar , Delgado H. Hernando 
Published: October 2016

En Boyacá la oferta de germoplasma de frijol mejorado es baja. El objetivo de este estudio fue evaluar el comportamiento agronómico de 18 líneas avanzadas volubles de frijol, procedentes del CIAT. Se utilizó el diseño bloques completos al azar, con tres repeticiones, incluyendo Bola Roja, Bolívar y Cargamanto como testigos. Se evaluó días a floración, vigor de crecimiento, días a madurez, incidencia de enfermedades, número de vainas/planta, número de granos/vaina, peso de 100 granos y rendimiento. Los genotipos MAC27, MAC13, MBC26, MBC28 y MBC37 no se diferenciaron del Cargamanto pero sí mostraron ser más precoces que Bola Roja y Bolívar. En días a madurez MAC27 y MBC39 fueron más tempranos que los testigos. Todos los genotipos se comportaron como resistentes a enfermedades, excepto MBC30 que resultó susceptible a Uromyces phaseoli y MBC33 a Phoma exigua. En número de vainas por planta, número de granos por vaina, peso de 100 semillas y rendimiento se destacaron MAC27 y LAS399, sin diferencia significativa frente a Cargamanto pero si superando a Bola Roja y Bolívar. Pese al efecto de las heladas en la fase final del ciclo, LAS399, MAC27 y Cargamanto produjeron rendimientos de 1300, 1038 y 950 kg/ha, respectivamente, mostrando las ventajas de su precocidad, en comparación a Bola Roja y Bolívar que son tardíos. Se concluye que LAS399 y MAC27, por su alta precocidad y resistencia a patógenos, son las líneas más promisorias para continuar la evaluación respecto a la posibilidad de ampliar la oferta de germoplasma de frijol voluble en Boyacá.

Published: October 2016

En el presente estudio se hace una descripción de la tecnología local de manejo de pasturas y se analizan las percepciones locales sobre el consumo de plantas por el ganado. Se estudia la clasificación local y valoración que los lugareños otorgan a las especies herbáceas y leñosas forrajeras presentes en los potreros. El estudio se realizó en la zona piloto del proyecto Pasturas Degradadas en Centroamérica (PD) en Muy Muy, Nicaragua. Los datos fueron obtenidos mediante diferentes técnicas de investigación cuantitativa y cualitativa. Se aplicaron técnicas cualitativas para recabar información en profundidad del acervo de conocimiento local respecto al uso de vegetación arbórea, arbustiva y herbácea en las fincas ganaderas. Se registró un total de 25 especies herbáceas forrajeras, siendo las variedades más reportadas la grama natural (Paspalum sp), pasto estrella (Cynodon plectostachyus K. Schum.) Pilg. y jaragua (Hyparrhenia rufa). De la misma manera, fueron identificadas las especies leñosas más frecuentes en las fincas ganaderas el guácimo (Guazuma ulmifolia Lam), madero negro (Gliricidia sepium Jacq.) y roble (Tabebuia rosea). Se concluye que el conocimiento de los productores es empírico y funcional. Esto significa que es derivado de la experiencia práctica y generalmente en función de las actividades realizadas por su propia voluntad o inducida por agentes externos
