Comparison of fine-scale spatial genetic structure of two sympatricRhododendronshrub species in forest habitat having different seed weights: A case study
Authors: Aizawa Mineaki , Nakayama Chisa , Ohkubo Tatsuhiro
Published: September 2017

Restricted seed dispersal is one of the most prevalent determinants of spatial genetic structure (SGS) at a fine spatial scale within a plant population.Rhododendron kaempferiandR. semibarbatumare common and coexistent Ericaceous species in the shrub layer of secondary deciduous broad-leaved forests in the northern Kanto District, central Japan. The two species have entomophilous flowers and are thought to have similar pollination styles. However,R. kaempferiproduces threefold heavier seeds thanR. semibarbatum. Therefore, we tested the hypothesis that the intensity of SGS was stronger inR. kaempferithan inR. semibarbatumin a forest stand. We comparatively examined the SGS for 73 individuals ofR. kaempferiand 36 individuals ofR. semibarbatumby using highly variable nuclear microsatellite loci. The analysis revealed significant SGS in both species at the shortest distance (<3 m); a measure to quantify SGS showed a counterintuitive result:R. semibarbatumexhibited stronger SGS thanR. kaempferi. This result might be explained by the ecological consequences ofR. semibarbatumproducing lighter seeds, which might have greater dispersal efficacy, but its safe sites could be more restricted than those ofR. kaempferi; in contrast,R. kaempferiproducing heavier seeds might have more limited seed dispersal, but its safe sites for seedling establishment could be more prevalent than those forR. semibarbatum. The different strategies for the trade-off between seed weight and site selection of the twoRhododendronspecies might be reflected in the difference in the intensity of SGS in this study plot.

Published: September 2017

The Theoretical Aspects of Erroneous Actions During the Process of Decision Making by Air Traffic Control evaluates the factors affecting the operational decision-making of a human air traffic controller, interacting in a dynamic environment with the flight crew, surrounding aircraft traffic and environmental conditions of the airspace. This article reviews the challenges of air traffic control in different conditions, ranging from normal and complex to emergency and catastrophic. Workload factors and operating conditions make an impact on air traffic controllers’ decision-making. The proposed model compares various operating conditions within an assumed air traffic control environment subsequently comparing them against a theoretically “perfect” air traffic control system. A mathematical model of flight safety assessment has been proposed for the quantitative assessment of various hazards arising during the process of Air Traffic Control. The model assumes events of various severity and probability ranging from high frequency and low severity up to less likely and catastrophic ones. Certain limitations of the model have been recognised and further improvements for effective hazard evaluation have been suggested.

Published: September 2017

Inertial system errors in case of using the new structural correction method have been determined. Inertial system errors, which determine the kinematic parameters of aircraft movement, are finally generated in the computing circuit. This is the part of inertial system structure which is presented as a closed loop with a feedback. The forward circuit of the main loop consists of several velocity and distance integrators connected in series. Accelerometer signal corrections are calculated in the feedback loop. New corrective circuits have been introduced to the inertial system structure. And the errors of the changed system have been determined. The structural corrective circuits got signals from exterior onboard navigation systems. The conducted research has shown that the use of structural corrective circuits in some cases leads to a considerable decrease of inertial system errors. It means that the new structural method of inertial system correction provides positive results. Further research of inertial system errors should be conducted for the case of its full structure.
Evaluating the Dynamics of Aircraft Crew Skill Development by Using the Results of Discrete Exercise Marking
Authors: Lešinskis Aloizs , Chatys Rafał
Published: September 2017

Aircraft crew training corresponds to the interactive learning models of sensorimotor skill acquisition, and the dynamics of skill acquirement can be approximated by the exponential trend. A model of 5-grade assessment of separate exercises is offered. It helps to calculate a resulting evaluation, in accordance with which the progress level of a discrete exercise is evaluated. Such an evaluation forms one of the points for the analytical construction of a learning curve using the Gaussian method. Possible applications of the learning curve are covered.

Parameters for the Characterization of Motor Vehicle Acceleration Ability
Authors: Pommers Juris Gunārs
Published: September 2017

For the characterization of vehicle acceleration, in addition to such common parameters as change of speed and acceleration in time, there should be applied one more parameter: change of acceleration increase in time. Change of acceleration increase in time jp progresses in four specific phases in each gear: I – beginning of run where jp is growing rapidly to the maximum value of the gear; II – jp reduction from the maximum value to the stabilized value; III – speeding up with stabilized value jp and IV – shifting when jp value is changing in a wide range to the maximum negative value and then to zero.

Authors: Feofanovs Viktors
Published: September 2017

The aim of this article is the development of the system and methodology of complex control and evaluation of vehicle operators performance during multifunctional simulation. In order to achieve the above-stated aim it is necessary to solve the following principal tasks: to elaborate a theoretical model of differentiated evaluation of vehicle operator training degree according to different kinds of their functional performance; to develop the method of the differential evaluation of crew performance on full-scale aviation simulators with due consideration of the probabilistic approach on the basis of statistical processing of the data of recorded flight information. The offered theoretical model of the differential evaluation of operator performance and the methodology of standards determination developed on its basis represent a new approach to the creation of automated systems for the objective evaluation of the trainees’ qualification degree. The elaborated system of differential evaluation standards ensures a high degree of objectiveness when evaluating the degree of the vehicle operator qualification and makes it possible to carry out a comparative analysis of the operators’ qualification.

Published: September 2017

White Etching Cracks (WECs) und White Etching Areas (WEAs) sind Schadensbilder , die oftmals in Wälzlagern (z . B. in Windkraftanlagen) auftreten (siehe Abb. 1). Es fehlt bisher eine Möglichkeit , WECs und WEAs in Wälzlagern frühzeitig zu detektieren, d. h. möglichst lange bevor die Oberflächenschädigung auftritt. In diesem Beitrag wird das Schwingungsverhalten des Innenrings eines Wälzlagers (Abb . 2) im beschädigten Zustand (mit WEAs und WECs) und im Neuzustand miteinander verglichen, um eine erste Aussage über das Potenzial der vibrationsbasierenden Messmethode zur Detektion der Ausbildung von WECs und WEAs zu treffen. Mit Hilfe von einem eigenentwickelten robotergesteuerten Vibrometer-Messsystem werden die Oberflächenschwingen beider Lagerzustände erfasst und miteinander verglichen. Für den Vergleich werden Kohärenzfunktion, Frequency-Response-Assurance-Criterion (FRAC) und Cross-Signature-Assurance-Criterion (CSAC) als Kriterien verwendet. Es wird gezeigt, dass durch die Kombination dieser drei Kriterien eine Detektion von WECs und WEAs in Wälzlagern möglich ist. Die flächenhafte Messung ist dabei notwendig und sollte, wenn möglich, mit mehreren Kanälen parallel durchgeführt werden.

Published: September 2017

In Leichtbaustrukturen wird der Polarisationszustand von integrierten Piezokeramiken mittels thermischer Anregung zerstörungsfrei geprüft. Wärmeschwingungen (Laser-Intensitäts-Modulations-Methode) oder Wärmeimpulse führen zu einem pyroelektrischen Strom im Frequenz- bzw. Zeitbereich. Das Frequenzspektrum wird analytisch mit Hilfe thermischer Relaxationszeiten, die den Wärmeverlust charakterisieren, beschrieben. Die Signale im Zeitbereich werden fourier-transformiert und mit der Übertragungsfunktion der Messstrecke korrigiert. Außerdem wird die mittlere Temperatur der Probe analytisch und numerisch ermittelt, um daraus das Zeitsignal des Stromes abzuleiten.

Dehnungsmessung an piezoresistiver polymerabgeleiteter Keramik
Authors: Tang Linbo , Rosenburg Felix , Nicoloso Norbert , Werthschützky Roland
Published: September 2017

Polymer-derived ceramics with piezoresistive properties consist of siliconoxycarbide nanocomposites (SiOC/C). In contrast to commercial (piezo-) resistive materials, SiCO/C nanocomposites have high pressure sensitivity and a high temperature resistance over 400°C. Because of its ceramic properties, SiOC/C can be modeled as a volume body and therefore does not require any additional spring elements. By varying the volume percent of the segregated carbon xc, above the percolation threshold (xc = 10 ... 20 vol%), the sensitivity can be influenced. The pressure sensitivity is systematically examined by bending and compression tests and compared with each other.

Towards a landscape archaeology of Buddhist cave-temples in China
Authors: Monteith Francesca
Published: September 2017

Buddhism spread from northern India throughout the Asian continent from the first century BC onwards. As it spread, it changed and adapted to suit the new peoples and customs with which it came into contact. In recent years, studies have been undertaken on the landscape archaeology of Indian, Central Asian and Southeast Asian Buddhism. By focusing on China, this study represents a preliminary step in attempting to illuminate a new aspect of early Buddhist practice in China. It considers the chronological implications of the way in which the sites are positioned within the landscape. The study is based on survey work and site visits undertaken over the last five years, during the course of which certain patterns began to emerge. Based on these observations, an initial hypothesis was formed which states that the visibility of the locations into which cave sites are carved increases over time. Visibility is taken as the presence or prominence of a site within the physical landscape. This study focuses only on rock-cut cave-temples because they can still be clearly seen within their (nearly) original landscape settings. They can also be dated with relative accuracy on stylistic grounds. The same cannot be said of surface religious structures.
A recent reconnaissance of the central Helmand Valley
Authors: Abramiuk Marc A.
Published: September 2017

Archaeological fieldwork in the central Helmand Valley of modern-day Afghanistan has been sparse as a result of the region's remoteness and lack of security; the work that has been done suggests that the area has been occupied since prehistoric times. The Central Helmand Archaeological Study (CHAS) is the most recent archaeological field research to be conducted in the valley. It was launched in 2011 with the support of the US Marine Corps and the Government of the Islamic Republic of Afghanistan, to locate and record archaeological sites in the region and to report any evidence of looting or damage (Abramiuk & Wong 2015). This paper reports on some early findings in the course of continuing analysis and provides a preliminary assessment.

McKinley-Barnard, SK, Andre, TL, Gann, JJ, Hwang, PS, and Willoughby, DS. Effectiveness of fish oil supplementation in attenuating exercise-induced muscle damage in females during midfollicular and midluteal menstrual phases. J Strength Cond Res 32(6): 1601–1612, 2018—The purpose of this study was to determine whether the differences in estrogen levels during the female menstrual cycle and fish oil supplementation would attenuate eccentric exercise-induced muscle damage and delayed-onset muscle soreness (DOMS). In a double-blind fashion, 22 physically active females (20.9 ± 1.4 years, 63.5 ± 9.0 kg, 165.2 ± 7.5 cm) were randomly assigned to ingest either 6 g of fish oil (n = 11) or placebo (n = 11) daily for 21 days. Participants underwent an eccentric exercise bout of the knee extensors on 2 occasions during the midfollicular (MF) and midluteal (ML) phases of the 28-day menstrual cycle. Before (PRE), at 6 (6HRPOST), and at 24 hours postexercise (24HRPOST) for each session, participants underwent assessments of DOMS, muscle strength, and had venous blood samples and muscle biopsies obtained. Data were analyzed using a 2 × 2 × 3 repeated-measures multivariate analysis of variance for each criterion variable (p ≤ 0.05). Further analysis of the main effects for the test was performed using separate 1-way analyses of variance. Delayed-onset muscle soreness was significantly greater at the 6HRPOST and 24HRPOST timepoints compared with PRE (p < 0.001). Superoxide dismutase and tumor necrosis factor-alpha (TNF-α) concentrations were significantly higher at the MF phase compared with the ML phase (p < 0.001 and p = 0.05, respectively). There were no statistically significant differences observed for muscle strength, myoglobin, NF-Kβ p50, or NF-Kβ p65. This study demonstrates that higher levels of estrogen may exert a cytoprotective effect on the sarcolemma.

Published: September 2017

A radial injection experimental setup is presented in this paper, which allows one to study the transport and deposition of suspended particles and permeability impairment in porous media. This setup allows one to simulate the conditions of the injection of produced water in oil reservoirs from an injection well. This is achieved by a radial injection of water containing suspended particles of a few microns in size from a central well including a sand screen, through a confined cylindrical sand pack (diameter 52 cm, height 40 cm). A peripheral drainage system permits the recovery of the fluid at the outlet of the sand pack by a collector equipped with a turbidimeter for measuring the concentration of suspended particles. The injection pressure is measured at the inlet, and six pore pressure probes have been installed at different locations inside the sand pack. First experimental results presented show a significant heterogeneity of deposited particle profiles in both radial and axial directions.

Published: September 2017

Mutations in genes encoding enzymes in the tricarboxylic acid cycle (TCA, also known as the Krebs cycle) have been implicated as causative genetic lesions in a number of human cancers, including renal cell cancers, glioblastomas and pheochromocytomas. In recent studies, missense mutations in the succinate dehydrogenase (SDH) complex have also been proposed to cause differentiated thyroid cancer. In order to gain mechanistic insight into this process, we generated mice lacking the SDH subunit D (Sdhd) in the thyroid. We report that these mice develop enlarged thyroid glands with follicle hypercellularity and increased proliferation. In vitro, human thyroid cell lines with knockdown of SDHD exhibit an enhanced migratory capability, despite no change in proliferative capacity. Interestingly, these cells acquire stem-like features which are also observed in the mouse tumors. The stem-like characteristics are reversed by α-ketoglutarate, suggesting that SDH-associated tumorigenesis results from dedifferentiation driven by an imbalance in cellular metabolites of the TCA cycle. The results of this study reveal a metabolic vulnerability for potential future treatment of SDH-associated neoplasia.

Knowledge and practice in mental health nursing care
Authors: Kurimoto Teresa Cristina da Silva , Penna Claudia Maria de Mattos , Nitkin Débora Isane Ratner Kirschbaum
Published: September 2017

ABSTRACT Objective: To understand mental health nursing care based on the concept of the subject of the unconscious proposed by Lacan. Method: A narrative study was carried out with 19 nurses, chosen based on their theoretical approach or referral by other participants, through the snowball sampling technique. The interviews were carried out in person or digitally, and were recorded and fully transcribed. Results: The analysis was carried out based on Freudian and Lacanian psychoanalysis, approaching nursing care as it acts on the body, secretions, and excretions, to distinguish it from the spirit of fineness. Effects on care are discussed, considering the subject of the unconscious with its knowledge, creating unique exits (sinthome). In this situation, professionals are required to abstain from a position of knowing what is better for the Other. Final considerations: This nursing care perspective offers contributions when discussing the centrality of the subject and words in the care process.

Encontrou-se uma correlação linear entre medicamentos prescritos e interações medicamentosas potenciais (p valor < 0,001). Conclusão O presente estudo identificou uma alta frequência de interações medicamentosas potenciais envolvendo fármacos de controle especial e uma associação positiva entre o número de fármacos prescritos com a maior frequência dessas interações.

Abstract Objective: To present the current recommendations for breast cancer screening in Brazil, as devised by the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Breast Disease Society, and the Brazilian Federation of Gynecological and Obstetrical Associations. Materials and methods: We analyzed scientific studies available in the Medline and Lilacs databases. In the absence of evidence, the recommendations reflected the consensus of a panel of experts. Recommendations: Annual mammography screening is recommended for women 40-74 years of age. Among women ≥ 75 years of age, annual mammography screening should be reserved for those with an expected survival > 7 years. Complementary ultrasound should be considered for women with dense breasts. Complementary magnetic resonance imaging is recommended for women at high risk. When available, an advanced form of mammography known as tomosynthesis can be considered as a means of screening for breast cancer.

Resumo: Devido às incertezas sobre o impacto dos cigarros eletrônicos na saúde, o Brasil adotou, em 2009, regulamentação que proibiu venda, importação e propaganda desses produtos até que fabricantes possam demonstrar que são seguros e/ou efetivos na cessação de fumar. O objetivo do estudo foi analisar entre fumantes brasileiros: (1) conhecimento sobre existência de cigarros eletrônicos, uso na vida, e uso recente; (2) percepção de risco sobre cigarros eletrônicos comparados a cigarros convencionais; e (3) fatores correlacionados ao conhecimento e percepção de risco. Este é um estudo transversal entre fumantes brasileiros (≥ 18 anos) usando amostra de reposição da Onda 2 do Inquérito Internacional sobre Controle do Tabaco. Os participantes foram recrutados em três cidades por meio de um protocolo de discagem randomizada entre outubro de 2012 e fevereiro de 2013. Entre os 721 respondentes, 37,4% (n = 249) dos fumantes atuais conheciam cigarros eletrônicos, 9,3% (n = 48) relataram ter experimentado ou usado alguma vez na vida e 4,6% (n = 24) ter usado nos últimos 6 meses. Entre os que conheciam cigarros eletrônicos, 44,4% (n = 103) acreditavam que eles eram menos nocivos que os cigarros regulares (baixa percepção de risco). A “baixa percepção de risco” foi associada com ter maior nível educacional e com ter experimentado/usado cigarro eletrônico recentemente. Apesar das restrições aos cigarros eletrônicos no Brasil, 4,6% dos fumantes da amostra relataram uso recente. Programas de vigilância em saúde do Brasil e demais países deveriam incluir questões sobre uso e percepções sobre cigarros eletrônicos considerando os respectivos ambientes regulatórios.

RESUMO: O objetivo deste artigo é fazer uma reflexão acerca dos espaços museológicos como prática educativa. Concebendo-os como um lazer diferenciado, tem-se uma falsa representação de que parte da população seria incapaz de usufruir de seus acervos. Partindo de uma perspectiva histórica acerca dos museus e da teoria de Pierre Bourdieu, procurou-se observar estruturas mentais que instauram barreiras culturais para algumas linguagens e práticas. Nesse sentido, como inspiração, visitaram-se alguns acervos no intuito de apreender as estratégias de aproximação e/ou afastamento de suas exposições. Para finalizar, problematizando o envolvimento com práticas de cultura responsáveis em grande parte pela formação de um capital cultural, provocou-se a reflexão sobre as diferentes formas de apreciar e de se sensibilizar com artefatos culturais diversos.

RESUMO Objetivo: identificar as forças impulsoras e restritivas envolvidas no processo de maternagem aos recém-nascidos hospitalizados em uma unidade de terapia intensiva neonatal. Método: pesquisa descritiva e exploratória, de abordagem qualitativa, que possui como referencial a Teoria de Campo de Forças. Participaram dez mães. Os dados foram coletados de setembro a dezembro de 2014, por meio de entrevista semiestruturada, e submetidos à análise de conteúdo. Resultados: comunicação efetiva, inclusão da família no cuidado, trabalho em equipe, aprendizagem e espaço físico adequado atuaram como forças que impulsionaram a maternagem. Condutas autoritárias, estigmas relacionados à unidade de terapia intensiva neonatal, falta de assistência especializada, não realizar cuidados ao recém-nascido, cansaço físico, estresse emocional e mudanças na rotina diária atuaram como forças que restringiram a maternagem. Conclusão: identificar o campo de forças possibilitou compreender fatores e situações que influenciam a maternagem e diagnosticar as verdadeiras demandas biopsicossociais das mães dos recém-nascidos hospitalizados.

RESUMO Objetivo: analisar os efeitos simbólicos da luta empreendida pelas integrantes do primeiro grupamento feminino de enfermagem das Forças Armadas brasileiras para serem reincluídas no Serviço Militar Ativo do Exército, após o término de suas atividades durante a Segunda Guerra Mundial. Método: pesquisa histórico-social cujas fontes constituíram-se de documentos escritos, orais e fotográficos. Os achados foram classificados, contextualizados e analisados em conformidade com o método histórico e à luz da Teoria do Mundo Social de Pierre Bourdieu e dos estudos de Michelle Perrot sobre a História das Mulheres. Resultados: a pesquisa demonstrou que os discursos destas enfermeiras, que atuaram no Teatro de Operações Italiano durante a guerra (1943-1945) e que foram reincorporadas ao Exército Brasileiro em 1957, apesar de reiterarem vocações e estereótipos sobre a prática de Enfermagem, trouxeram a lume os resquícios de uma luta propriamente simbólica pela conquista inédita de espaço, poder e prestígio para a profissão nesse campo culturalmente masculinizado. Conclusão: a reinclusão dessas enfermeiras no Serviço Militar Ativo do Exército serviu de fundamentação para a criação de novos corpos militarizados femininos no âmbito das Forças Armadas, a partir da década de 1980.
A informação como elemento de integração entre propósito, processos e pessoas: um estudo em instituições portuguesas

Resumo Para que o gerenciamento da informação seja efetivo no cumprimento de seu objetivo deve-se saber com clareza o que é a informação para a empresa, quem a possui, como é conservada, quem é o responsável pelo seu gerenciamento, como controlar e utilizar a informação. Esta pesquisa tem por objetivo avaliar o papel da informação como elemento integrador do propósito, do processo e das pessoas em organizações de captação, processamento e disseminação de informação em organizações portuguesas. É uma pesquisa interdisciplinar e insere-se no contexto da Ciência da Administração e da Ciência da Informação no aspecto em que a informação e seus fluxos colaboram com os vários componentes do processo de alinhamento estratégico da organização. O estudo de natureza exploratória adotou uma metodologia multicaso. Foram estudados três casos de organizações portuguesas. Os dados foram recolhidos através de entrevistas semiestruturadas com profissionais da gestão das organizações pesquisadas. Os casos foram analisados individualmente e, posteriormente, procedeu-se à sua análise comparativa. Os resultados obtidos indicam que, apesar da centralidade da informação no seu propósito estratégico, as organizações pesquisadas não utilizam a informação em sua gestão interna e não revelam a mesma efetividade que possuem na prestação desses serviços informacionais.
Integrando sustentabilidade ambiental e gestão de portfólio de projetos: estudo de caso em uma empresa de energia
Authors: Jugend Daniel , Figueiredo José
Published: September 2017

Resumo: Apesar de existirem muitos trabalhos sobre sustentabilidade ambiental, por um lado, e sobre gestão de portfólio de projetos, por outro, não há pesquisas que analisem esses temas de maneira integrada. Assim, as duas áreas seguem separadas e com apenas raras interfaces teórico-empíricas. Seguindo uma estratégia de estudo de caso em uma das maiores firmas europeias de energia, que se destaca mundialmente na produção de energias renováveis, este artigo tem como principal objetivo analisar e compreender as práticas adotadas para a integração das duas componentes, sustentabilidade ambiental e gestão de portfólio. Entre os principais resultados obtidos observou-se que os aspectos ambientais e sociais são indissociáveis nos principais projetos da empresa. A boa comunicação com stakeholders e, especialmente, com as comunidades locais e as diretamente afetadas pelos projetos também foi destacada como prática de gestão que pode ser empregada para melhorar o desempenho de projetos. Notou-se também que a lógica para a análise e aprovação de projetos na empresa, admissão de projetos para o portfólio empresarial também se pauta pelas análises das externalidades ambientais e sociais previstas pelos próprios projetos.

Abstract In recent decades, the rise violent phenomena in Brazil has reached epidemic proportions. However, the prevalence of domestic violence (DV) across different states in the country is not well established. The objective of this study was to describe the distribution of DV across Brazilian states from 2009 to 2014. An ecological study based on spatial analysis techniques was performed using Brazilian states as geographical units of analysis. A multilevel Poisson model was used to explain the risk of DV in Brazil according to age, sex, period (fixed effects), the Human Developing Index, and the victim’s residence state (random effects). The overall average rate of DV almost tripled from 2009-2010 to 2013-2014. The rate of DV in Brazil in the 2013-2014 period was 3.52 times greater than the 2009-2010 period. The risk of DV in men was 74% lower than in women. The increase of DV against women during period under study occurred mainly in the Southeast, South, and Midwest. DV was more frequent in adolescence and adulthood. DV is gradually increasing in recent years in Brazil. More legislation and government programs are needed to combat the growth of violence in society.
