Deterrence in Indo-Pak Context: A Critical Appraisal
Authors: Ahmad Khan  , Ali Ahsan
Published: February 2016

It was an imbalance in the conventional power that forced Pakistan to see nuclear weapons' capability, as a deterrence against India, after the war of 1971 that resulted in separation of former East Pakistan. This is the context of ‘deterrence’ in today's South Asia. The only solution to the dilemmas created by the region's nuclearization is to engage seriously and constructively to build a better understanding of each other's conventional and nuclear policies, doctrines, and postures, and meaningful CBMs both in nuclear and conventional military spheres to build trust and confidence. Both India and Pakistan have to maintain rational decision-making to ensure the credibility of their deterrence and to achieve the objective of maintaining stability.
Nasr: A Product of Pakistan's Strategic Culture
Authors: Muhammad Umar
Published: February 2016

After the dismal failure of Operation Parakram, India went back to the drawing board and developed a new limited war strategy, referred to as the Cold Start Doctrine, with the aim of quick mobilization of their troops to Pakistan's border, from where they could launch conventional strikes against Pakistan and at the same time not escalate the conflict to full scale or to the nuclear level. In response to India's Cold Start Doctrine, Pakistan introduced tactical nuclear weapons. To understand why Pakistan developed the tactical nuclear weapons we must try to understand their strategic culture. The paper will argue that the Cold Start Doctrine is in fact real and can be materialized, and for that reason Pakistan has had to respond to the threat it poses. In this paper we will try to understand Pakistan's response to the Cold Start Doctrine by trying to grasp its strategic culture.
Nothing to see here? Health Goth and the eclipse of hypercamouflage
Authors: Matts Tim , Sutherland Dane , Tyler Gary
Published: February 2016

Displacing the dialectical negativity of traditional or ‘kitsch’ Marxism, accelerationism names a contemporary heresy. The affirmative orientation of the movement seeks instead to strategically harness the capitalist mode of production, and the historical material conditions it has sired, to intensify, destabilize and ultimately exhaust the present neo-liberal deadlock. With its anti-nostalgic, putatively ‘transhuman’ embrace of technical sportswear, biotechnologies and digitally rendered environments, the recent ‘Health Goth’ phenomenon, which first emerged as an aesthetic and social trend centred around an Internet community in 2013, therefore, at first blush, appears quintessentially accelerationist. In the interview-essay that follows, however, we pose a series of questions to Chris Cantino, one of Health Goth’s chief instigators, in a bid to open up further, speculative appropriations of a movement that itself stems from practices of détournement. Whilst acknowledging that the movement may indeed be characterized in accelerationist terms, a characterization that would moreover resonate with Malcolm Gladwell’s notion of the ‘Tipping Point’ as social epidemic, particularly insofar as it is one so overtly enabled and stimulated by the spectacular affect of sportswear fashion, we propose that it nevertheless exceeds this first order of reception, chiefly by eclipsing the accelerationist concept of hypercamouflage.
Orchestrating the edge: Towards a noisy point cloud onto-epistemology
Authors: Pearce Thomas
Published: February 2016

The way we understand and use emerging technologies will always be informed by a set of tacit philosophical assumptions, psychological mechanisms and techniques of governance. The discourse surrounding 3D scanning, a technology on the verge of becoming ubiquitous, is one of veracity and accuracy: the scanner is treated as an immaterial camera obscura and an ultimate facilitator of objective knowledge. This article discusses a design-research project that dismantles such assumptions and recuperates notions of noise, multiplicity and ambiguity within the point cloud. This is supported by a deconstruction of the ontological and epistemological foundations (such as representationalism, atomism and essentialism) on which the ‘realism’ of the scanner is grounded. Referencing to post-structuralist theory, theoretical physics and science studies (and to Karen Barad in particular) the article formulates an alternative onto-epistemological framework that instead emphasizes the material nature of knowing and notions of becoming and multiplicity. Equally, while revolving around and always returning to 3D scanning technology, the article extrapolates its findings towards a critical analysis of contemporary modes of governance. Central to the argument is a process of physical prototyping exploring a phenomenon called ‘edge noise’: these are ‘ghost points’ in a 3D scan created by mixed measurements at the edge of an object. The multiplicity of these faulty and fictional measurements is explored as a productive schizophrenic condition that dismantles the reductionist logic of point cloud filtering. More crucially, this edge noise is then reverse-engineered, enabling the designer to actively and precisely create this edge noise using algorithmically controlled perforated screens. Finally, the article discusses two architectural design projects that implement the developed edge noise algorithms and unpack its philosophical, technological and political considerations. These projects propose an approach towards the point cloud that, rather than treating the scanner as an immaterial and realist conveyer of truth, involves it as the designer’s and observer’s creative complicit in the very forging of phenomena.
In quest of code
Authors: Werner Liss C.
Published: February 2016

Architects who apply their generative modelling and scripting skills for creating virtual and prototypical spaces through the usage of algorithms and bespoke coding are increasingly confronted with an application in the real material world. The article suggests computational design strategies leading to architectural and urban for an era in which intelligent material, robotic assistants, smart geometries and changing human habitat converge with demographic, cultural and natural earth data to govern a global rethinking of socio-architectural ecologies. Since the beginning of humankind, our planet Earth has served as feeding ground and shelter. Civilization and industrialization have triggered a verification of territory, ownership, economic wealth and power. Henceforth, ethical rules, societal regulation and intuitive values were partly overridden and replaced. Long-distant transport vehicles such as cargo ships and trains allowed for accelerating the mixing up of goods and technologies. Architects solved industrial and infrastructural problems with new ideas and emerging building types, shaping urban and peripheral environments. A great idea manifested through extensive exchange of cultures and knowledge, however strangely enough climaxed in an ultimate exploitation of our natural resources – a situation we can hardly understand or handle. As a result we are facing a situation of re-scripting our human, urban and architectural ecological system. Thus the article touches upon this very shift starting in the eighteenth century, traversing through the implementation of the Internet, to regulate our physical world and data-autobahns filled with informing bits and bytes. The question is, which questions to ask for the best solution we can offer.
The architecture of post-cinema
Authors: Moore James
Published: February 2016

Open Montage (OM) is an interactive video project problematizing the position of the moving image in contemporary network culture. Digital communication systems afford the possibility for user experience designers to reflect on a weakening of hierarchical narratives of power and representation; yet, the tendency towards an unthinking remediation of prior (televisual) media types and hierarchies persists. As a consequence of new, yet often aesthetically primitive communication design formations manifesting online, it is argued that tactics of image assembly and montage must be developed to afford users a wider and more expressive range of visual language building communication tools. If the interaction design imperative is not to suspend but encourage disbelief as a condition in the user, how can this be approached as a design problem?

The sensor has a similar response to the human eye is ideal for applications in photometry. The performance of the instrument was compared to a commercial model CR-10, in which a linear relationship was obtained between the chromaticity coordinates of the two units, with the calibration performed with 60 samples of colored powder.
Hydrolytic soil enzymes and their response to fertilization: a short review
Authors: Bautista-Cruz Angélica , Ortíz-Hernández Yolanda Donají
Published: February 2016

Enzymes are proteins that catalyze chemical reactions in living systems, transforming specific substrates into the products needed in biological cycles and for many edaphic processes. Soil enzymatic activities have been proposed as soil quality indicators, due to their relation with soil biology. Although the long-term effects of organic and mineral fertilization on physical and chemical soil properties have been previously studied, little is known about their effects on microbial community structure, microbial biomass carbon, microbial activity and enzymatic activity. Some studies report that organic and mineral fertilizers can affect, be it positively or negatively, microbial biomass size as well as soil microbial activity. This work examines the effect of fertilization on the enzymatic activity of soil hydrolases.
IDENTIFICATION OF DAMAGED ZONES IN C/PPS SPECIMENS SUBJECTED TO FATIGUE LOADING BASED ON HIGH-RESOLUTION THERMOGRAPHY
Authors: Koudelka Petr , Kytýř Daniel , Fenclová Nela , Šperl Martin
Published: February 2016

In this study high resolution thermography is used for identification of damaged zones in Carbon fiber/polyphenylene sulfide (C/PPS) long fiber composite specimens with induced impact damage subjected to tensile fatigue loading. Image processing techniques were applied on thermographs from all loading cases to obtain segmented images of the damaged location that were then used for calculation of the heated area. Results show that the considered method can be used to identify heated area in the vicinity of damage with high confidence at low number of cycles where no significant fatigue effect is present in the material.
PRELIMINARY ASSESSMENT OF THE CHANGE IN THE MECHANICAL BEHAVIOR OF SYNTHETIC YARNS SUBMITTED TO CONSECUTIVE STIFFNESS TESTS
Authors: Stumpf Felipe Tempel , Guilherme Carlos Eduardo Marcos , Chimisso Fulvio Enrico Giacomo
Published: February 2016

Anchoring systems of offshore platforms are designed to work uninterruptedly for 20 to 30 years, and despite the increasing number of studies concerning these systems’ mechanical behavior in working conditions, most of them are conducted in speeding environments, due to the necessity of results in the short term. There are standardized stiffness tests, such as ISO 18692, based on quantities like Dynamic Stiffness and Quasi-static Stiffness, through which one can compare, quantitatively, two different ropes. However, there is a lack of research aiming to assess the change in the mechanical behavior of these ropes after certain number of consecutive loading cycles (or stiffness tests). This study aims to assess, at the yarn level, the change in the quasi-static and dynamic stiffness parameters of two materials when submitted to repeated stiffness tests. Results in terms of qualitative assessment of the mechanical behavior, as well as quantitative changes in the parameters are presented.

Authors: Sykora Henrik Tamás , Kovács Attila , Bachrathy Dániel
Published: February 2016

In the design phase of the milling process, there is a great need for the prediction of the cutting force, the required torque and power of the spindle. These informations could be used to optimize the tool path and improve the material removal rate. In this work, we present our dexel based simulation software, its modules, calculations steps and the simulation method. Different force models were analysed to describe the specific force as a function of the local chip thickness. The models were fitted to the measured force data. Then the selected force model was validated in case of a complex tool path.
Attitudes towards work in Educational Institutions

Published: February 2016

The current study aims to evaluate employees’ attitudes towards work in educational institutions. An attitude scale was developed in order to reach the researchs ub-purposes. The scale was administered to the selected sample to obtain the research findings. Survey model, a quantitative Research method, was used within the current research. The Research population consists of Education employees working in schools under department of education in the town of Corlu, city of Tekirdag. 312 administrators, 1878 teachingand 480 supportive staff worked in 98 schools in the town of Corlu when the Research was conducted. 215 participants within the research sample were selected through non-proportional quota sampling among the teachers working in schools in the town. A scale to measure attitudes toward work was used as the data collection tool within the research. Some statistical analyses were needed in order to define the Research sub-dimensions. SPSS 21 software package was used to analyze the data. One-way variance analysis (ANOVA), t-test, Tukey, and LCD tests were used in the analyses. Employees considered their works in five different dimensions. When employees’ attitudes toward work are examined based on their demographic characteristics, it is seen that employees’ age,  genders and seniority were a significant factors defining their attitudes toward work. The employees’ attitudes toward work at educational institutions were examined in the current study. The five dimensions defined within the research results must be considered significant for employees at educational institutions and some incentives must be activated.

Medical data preprocessing for increased selectivity of diagnosis
Authors: Walczak Andrzej , Paczkowski Michał
Published: February 2016

In this review, we present a framework that will enable us to obtain increased accuracy of computer diagnosis in medical patient checkups. To some extent, a new proposition for medical data analysis has been built based on medical data preprocessing. The result of such preprocessing is transformation of medical data from descriptive, semantic form into parameterized math form. A proper model for digging of hidden medical data properties is presented as well. Exploration of hidden data properties achieved by means of preprocessing creates new possibilities for medical data interpretation. Diagnosis selectivity has been increased by means of parameterized illnesses patterns in medical databases.
Possible involvement of endoplasmic reticulum stress in the pathogenesis of Alzheimer’s disease
Authors: Hosoi Toru , Nomura Jun , Ozawa Koichiro , Nishi Akinori , Nomura Yasuyuki
Published: February 2016

The endoplasmic reticulum (ER) is an organelle that plays a crucial role in protein quality control such as protein folding. Evidence to indicate the involvement of ER in maintaining cellular homeostasis is increasing. However, when cells are exposed to stressful conditions, which perturb ER function, unfolded proteins accumulate leading to ER stress. Cells then activate the unfolded protein response (UPR) to cope with this stressful condition. In the present review, we will discuss and summarize recent advances in research on the basic mechanisms of the UPR. We also discuss the possible involvement of ER stress in the pathogenesis of Alzheimer’s disease (AD). Potential therapeutic opportunities for diseases targeting ER stress is also described.

Authors: Harmer Stephen C. , Tinker Andrew
Published: February 2016

Long QT syndrome refers to a characteristic abnormality of the electrocardiogram and it is associated with a form of ventricular tachycardia known as torsade-de-pointes and sudden arrhythmic death. It can occur as part of a hereditary syndrome or can be acquired usually because of drug administration. Here we review recent genetic, molecular and cellular discoveries and outline how they have furthered our understanding of this disease. Specifically we focus on compound mutations, genome wide association studies of QT interval, modifier genes and the therapeutic implications of this recent work.

Authors: Hussain S. T. , Ul Haq Rizwan , Noor N. F. M. , Nadeem S.
Published: February 2016

Present phenomenon is dedicated to analyze the combine effects of linear and non-linear Rosseland thermal radiations for stagnation point flow along a vertically stretching surface. For better variation in fluid flow and heat transfer, mixed convection is also considered to sustain this mechanism for significant influence. After incorporating these effects, the pertinent mathematical model is constructed in the form of non-linear partial differential equations and then be transformed into the system of coupled ordinary differential equations with the help of similarity transformation to be further solved numerically. Significant difference in the heat transfer enhancement can be observed through temperature profiles and tables of Nusselt number. Though histogram and isotherms plots, finally it is concluded that non-linear radiation provides better heat transfer rate at the surface of sheet as compare to the linear or absence of radiation effects.

Authors: Yang Jie , Wang Jingang , Luo Ruixi , Gao Can , Songnong Li , Kongjun Zhou
Published: February 2016

The development trend of future voltage transformer in smart grid is non-contact measurement, miniaturization and intellectualization. This paper proposes one simulation test system of non-contact D-dot transformer for voltage measurement. This simulation test system consists of D-dot transformer, signal processing circuit and ground PC port. D-dot transformer realizes the indirect voltage measurement by measuring the change rate of electric displacement vector, a non-contact means (He et al. 2004, Principles and experiments of voltage transformer based on self-integrating D-dot probe. Proc CSEE 2014;15:2445–51). Specific to the characteristics of D-dot transformer signals, signal processing circuits with strong resistance to interference and distortion-free amplified sensor output signal are designed. WIFI wireless network is used to transmit the voltage detection to LabVIEW-based ground collection port and LabVIEW technology is adopted for signal reception, data processing and analysis and other functions. Finally, a test platform is established to simulate the performance of the whole test system of single-phase voltage transformer. Test results indicate that this voltage transformer has sound real-time performance, high accuracy and fast response speed and the simulation test system is stable and reliable and can be a new prototype of voltage transformers.
A Unique Research Data Infrastructure for Educational Research and Beyond: The National Educational Panel Study
Authors: Fuß Daniel , von Maurice Jutta , Roßbach Hans-Günther
Published: February 2016

The article provides an insight into the conceptual and methodological framework as well as the research data infrastructure of the German National Educational Panel Study (NEPS). The NEPS study has been set up to build a profound empirical basis for the description and analysis of educational processes and competence development across the life span. Its large-scale database consists of longitudinal information from more than 60,000 target respondents – distributed over six different starting cohorts ranging from newborns to adults – and from relevant context persons such as parents or teachers. The complex multicohort sequence design schedules annual or even semiannual survey waves including a broad spectrum of competence assessments. All data are thoroughly prepared, documented, and disseminated free of charge in the form of regularly expanded Scientific Use Files. In addition to some background information about NEPS in general, this paper primarily focuses on issues of data collection, data structure, data availability, and the requirements for different types of data access. The number of more than 1,000 data users involved in over 700 research projects so far serves to highlight the potential of NEPS as a unique research data infrastructure for educational research and beyond.
A Lattice Boltzmann Model for Oscillating Reaction–Diffusion
Authors: Rodríguez-Romo Suemi , Ibañez-Orozco Oscar , Sosa-Herrera Antonio
Published: February 2016

A computational algorithm based on the lattice Boltzmann method (LBM) is proposed to model reaction–diffusion systems. In this paper, we focus on how nonlinear chemical oscillators like Belousov–Zhabotinsky (BZ) and the chlorite–iodide–malonic acid (CIMA) reactions can be modeled by LBM and provide with new insight into the nature and applications of oscillating reactions. We use Gaussian pulse initial concentrations of sulfuric acid in different places of a bidimensional reactor and nondiffusive boundary walls. We clearly show how these systems evolve to a chaotic attractor and produce specific pattern images that are portrayed in the reactions trajectory to the corresponding chaotic attractor and can be used in robotic control.

An analytical approach for fantasy football draft and lineup management
Authors: Becker Adrian , Sun Xu Andy
Published: February 2016

In this paper, we consider fantasy football, an increasingly-popular online game based on the actual, on-the-field performances of players in the National Football League. It is estimated by the Fantasy Sports Trade Association that in 2011 there were 35 million people in the US and Canada playing fantasy sports online. About 85 percent of all fantasy sports participants play fantasy football, most of whom have their games set up in major media websites such as Yahoo!, ESPN, MSN, and NFL. Numerous websites specialize in reporting NFL games, providing preseason rankings, fantasy points projections, team and player statistics, and expert draft opinions. However, despite the vast popularity of the game, the intensive analysis by experts, and various online tools that offer prediction for the values of players, to the best of our knowledge, there is no method that provides a comprehensive optimization strategy for the entire Fantasy Football season. We set out to develop such a methodology that predicts team and player performance based on the rich historical data, and builds a mixed-integer optimization model using such predictions for the draft selection as well as weekly line-up management that incorporates the entire objective of winning a fantasy football season. Numerical tests of our model show promising performance.
Modeling and forecasting the outcomes of NBA basketball games
Authors: Manner Hans
Published: February 2016

This paper treats the problem of modeling and forecasting the outcomes of NBA basketball games. First, it is shown how the benchmark model in the literature can be extended to allow for heteroscedasticity and estimation and testing in this framework is treated. Second, time-variation is introduced into the model by introducing a dynamic state space model for team strengths. The in-sample results based on eight seasons of NBA data provide weak evidence for heteroscedasticity, which can lead to notable differences in estimated win probabilities. However, persistent time variation is only found when combining the data of several seasons, but not when looking at individual seasons. The models are used for forecasting a large number of regular season and playoff games and the common finding in the literature that it is difficult to outperform the betting market is confirmed. Nevertheless, a forecast combination of model based forecasts with betting odds can lead to some slight improvements.
Daily activity pattern of reintroduced giant anteaters (Myrmecophaga tridactyla): effects of seasonality and experience
Authors: Di Blanco Yamil E. , Spørring Karina L. , Di Bitetti Mario S.
Published: February 2016

We assessed the effect of seasonality and intrinsic conditions on daily activity pattern of giant anteaters reintroduced in the Iberá Reserve, Argentina. During 2007–2012 we gathered 159 24-h focal samples on 15 radio-marked individuals (11 captive-reared, four wild-reared; seven adults, eight juveniles), 216 records of beginning and end of activity bouts on 20 individuals, and 454 camera-traps records (3345 trap-days). We estimated the daily hours of activity, the percentage of diurnal and nocturnal activity, and the daily activity range and time overlap using time as a circular variable in kernel density estimations. We assessed differences between seasons, sexes, age classes, and types of rearing. The average daily hours of activity was 8:43 h. Camera-traps and radio-telemetry showed similar results. Animals exhibited both diurnal (60–65%) and nocturnal (40–35%) activity. The higher probability for being active ranged within 09:00–03:00 h. Anteaters spent more hours active and were more nocturnal during summer. Activity was highly overlapped between sexes, and wild-reared individuals were more nocturnal than captive-reared ones. Seasonal shifts in daily activity highlights the importance of thermoregulation as a selective factor in this species. The giant anteater is a cathemeral species with flexibility to accommodate its activity pattern to local conditions or experience.
Palmitoylated PrRP analog decreases body weight in DIO rats but not in ZDF rats

Published: February 2016

Anorexigenic neuropeptides produced and acting in the brain have the potential to decrease food intake and ameliorate obesity, but are ineffective after peripheral application, owing to a limited ability to cross the blood–brain barrier. We have designed lipidized analogs of prolactin-releasing peptide (PrRP), which is involved in energy balance regulation as demonstrated by obesity phenotypes of bothPrrp-knockout andPrrpreceptor-knockout mice. The aim of this study was to characterize the subchronic effect of a palmitoylated PrRP analog in two rat models of obesity and diabetes: diet-induced obese Sprague–Dawley rats and leptin receptor-deficient Zucker diabetic (ZDF) rats. In the rats with diet-induced obesity (DIO), a two-week intraperitoneal treatment with palmitoylated PrRP lowered food intake by 24% and body weight by 8%. This treatment also improved glucose tolerance and tended to decrease leptin levels and adipose tissue masses in a dose-dependent manner. In contrast, in ZDF rats, the same treatment with palmitoylated PrRP lowered food intake but did not significantly affect body weight or glucose tolerance, probably in consequence of severe leptin resistance due to a nonfunctional leptin receptor. Our data indicate a good efficacy of lipidized PrRP in DIO rats. Thus, the strong anorexigenic, body weight-reducing, and glucose tolerance-improving effects make palmitoylated PrRP an attractive candidate for anti-obesity treatment.
Prostaglandin F2α promotes angiogenesis and embryo–maternal interactions during implantation
Authors: Kaczynski Piotr , Kowalewski Mariusz P , Waclawik Agnieszka
Published: February 2016

Implantation in humans and other mammals is a critical period during which high embryonic mortality rates occur. Prostaglandins (PGs) are key mediators regulating interactions between the reproductive tract and the conceptus (embryo with extraembryonic membranes). Although the significance of PGF2α as a regulator of corpus luteum regression is well established, the role of its high amounts in the uterine lumen in most mammals, regardless of placentation type, during the implantation period remains unresolved. We hypothesized that PGF2α acting as an embryonic signal mediator contributes to pregnancy establishment. Using a porcine model, we demonstrated that the conceptus and its signal (estradiol-17β) elevated endometrial expression of PGF2α receptor (PTGFR)invivoandin vitro. PTGFR protein was expressed mainly in luminal epithelial (LE) and glandular epithelial cells and blood vessels in the endometrium. PGF2α stimulated the MAPK1/3 pathway in endometrial LE cells that coincided with elevated gene expression and secretion of endometrial vascular endothelial growth factor A (VEGFA) protein. PGF2α–PTGFR and adenylyl cyclase signaling were involved in this process. PGF2α-induced VEGFA acting through its receptors stimulated proliferation of endometrial endothelial cells. Moreover, PGF2α elevated gene expression of biglycan, matrix metalloproteinase 9, transforming growth factor β3, and interleukin 1α in the endometrium. In summary, our study indicates that PGF2α participates in pregnancy establishment by promoting angiogenesis and expression of genes involved in tissue remodeling and conceptus–maternal interactions in porcine endometrium during early pregnancy.

Purpose: to study interconnections of students’ morphological functional indicators and their influence on level of sportsmanship. Material: in the research 17 students, practicing martial arts, participated. 62 indicators were determined: anthropometrical, goniometrical criteria of arms joints’ status; tapping test and maximal frequency of grabs in impulse mode. Results: we found that maximal contribution in system is made by hand dynamometry of right and left hands, body length and mass, chest circumference, width of shoulders; maximal frequency of grabs by right and left hands. It was confirmed that there are correlations between students’ morphological functional indicators. The highest contribution to formation of functional system is characteristic for anthropometric indicators. Results of maximal grabs in impulse mode made rather sufficient contribution in system’s formation that is confirmed by great quantity of correlations. Analysis of character, strength and orientation of correlations witnesses about informative potential of this test and permits to recommend it as screening for control of sportsmen’s state. Conclusions: we determined that indicators of hand dynamometry system formation illustrate that for martial arts wrestlers strong grab was very important. It is ensured by strength of hand muscles.

Resumo Introdução A criação de gado no sul da Amazônia tem crescido rapidamente, sendo que o Mato Grosso é um dos primeiros estados na produção de carne. Esse crescimento permitiu a contratação de mais trabalhadores para a atividade de refrigeração, trazendo um aumento de acidentes de trabalho nesse setor. Objetivo Analisar a influência de abate de gado nos acidentes de trabalho e sua distribuição espacial no estado de Mato Grosso, Brasil. Métodos Estudo ecológico que investigou a autocorrelação espacial global das taxas de acidentes de trabalho e o número de bovinos abatidos em municípios de Mato Grosso, usando a estatística Moran “global” pelo método LISA e, posteriormente, uma regressão múltipla espacial, tendo como variáveis de exposição o abate de cabeças de gado e, como variável resposta, a taxa de acidentes de trabalho. Resultados Foram encontrados padrões espaciais globais na distribuição do número de cabeças de gado abatidas. Na regressão múltipla, foram observadas correlações estatisticamente significantes entre o número de bovinos abatidos e a taxa de acidentes de trabalho. Conclusão O abate de gado está relacionado ao aumento do número de acidentes de trabalho no Estado de Mato Grosso, Brasil.
Crescimento linear das crianças brasileiras: reflexões no contexto da equidade social
Authors: PEDRAZA Dixis FIGUEROA
Published: February 2016

O artigo teve por objetivo refletir a respeito do crescimento linear das crianças no contexto da equidade social e sistematizou, primeiramente, os resultados das pesquisas que analisaram fatores associados ao declínio do deficit de estatura das crianças menores de cinco anos no Brasil. Posteriormente, os resultados foram contextualizados do ponto de vista da equidade social. Os nove artigos revisados mostraram variação temporal positiva do deficit de estatura, com valores nacionais que oscilaram de 37,1 a 7,1%; na região Nordeste a variação foi de 33,9 a 5,9%. Quatro razões principais explicaram o declínio do deficit de estatura: 1) aumento do poder aquisitivo/renda familiar nos lares de baixo poder aquisitivo; 2) melhoria da escolaridade materna; 3) expansão da rede pública de saneamento básico, e 4) expansão dos cuidados básicos de saúde. Porém, destacam-se disparidades que marcam a persistência das iniquidades sociais relacionadas ao deficit de estatura no País, as quais prejudicam populações marginalizadas. Enfoca-se a necessidade de refletir a baixa estatura na perspectiva da influência mediada pela situação da segurança alimentar, do estado nutricional de micronutrientes e dos modos de vida contemporâneos. Na perspectiva das políticas públicas, ressalta-se a importância do trabalho intersetorial. Em conclusão, sugere-se que apesar do declínio do deficit de estatura no Brasil, como reflexo do impacto das políticas públicas, ainda persistem iniquidades com vulnerabilidade marcada em grupos socioculturais desfavorecidos. Assim, o enfrentamento desta conjuntura torna imprescindível o direcionamento das pesquisas e das ações para esses segmentos populacionais.

The International Symposium on Zeolite and Microporous Crystals 2015 (ZMPC2015) was held at the Sapporo Convention Center, Japan, from 28th June to 2nd July 2015 and had 435 attendees from 32 countries, with 75% from Japan, China, Korea or Taiwan. 396 presentations covered all aspects of zeolites and microporous crystals over four days. Catalysis and synthesis were the two main themes (46% of all presentations) with the others being: new porous materials; membranes and films; adsorption and diffusion; characterisation; novel applications; industrial applications; layered materials; computational chemistry; post-synthetic treatment; crystallography; and ion exchange. There were six plenary talks along with 17 keynote and 94 oral presentations that took place in three parallel sessions. There were two poster sessions for 250 posters and recent research reports.
Manganese removal by hydrogen peroxide and biofiltration

Biofiltration has gained more attention as an alternative filtration for the removal of manganese (Mn) in both groundwater and surface water. This study investigated the potential of biofiltration as pretreatment at the Bennery Lake Water Treatment Plant located in Halifax, Nova Scotia, for the removal of manganese and dissolved organic carbon (DOC) from pH 6 natural lake water. A bench-scale study identified the effect of oxidant enhancement with hydrogen peroxide (H2O2), nutrient enhancement with phosphorus (P) and medium type (granular activated carbon (GAC) and anthracite) on a biofiltration system. Addition of both the nutrient, phosphorus (300–500 µg/l), and the oxidant, hydrogen peroxide (0·5 mg/l) enhanced the biofiltration performance, achieving 98% manganese removal and 27% (1·3 mg/l) DOC removal. Overall, the medium was not a significant factor for manganese removal, while GAC removed significantly more DOC than anthracite, although further treatment would be required for either medium to achieve lower DOC concentrations. These results show direct biofiltration of surface water at pH 6 can remove manganese below the 50 µg/l aesthetic guideline from a manganese loading of over 1 mg/l. This work highlights a potential mechanism and implication of biological roughing filtration technique for the removal of manganese and DOC from natural surface water.

Finalizando o Jogo dos Sete Erros no processo de submissão de artigos científicos, este editorial discorre sobre a importância da leitura das normas dos periódicos e a publicação de manuscritos. Em relação à submissão de artigos, primeiramente, é imperativo que os autores conheçam o escopo das revistas que irão submeter os resultados de seus estudos. Qualquer autor pode oferecer um artigo científico a ser apreciado para publicação em alguma revista, entretanto, devem realizar a leitura das normas para submissões dos manuscritos e segui-las. No intuito de facilitar o processo de publicação de artigos, o OBJN disponibiliza em sua homepage tutoriais para instruir os autores, além da criação de uma nova seção de submissão intitulada de Notas de Pesquisa, tendo como objetivo a publicação de artigos curtos de pesquisa com a apresentação de seus resultados parciais. Assim, é primordial que os autores façam a leitura rigorosa das normas de publicação a fim de facilitar a elaboração de seus manuscritos e consequente publicação dos resultados de seus estudos.
