Published: November 2016

Abstract
Stability of mining openings requires consideration of a number of factors, such as: geological structure, the geometry of the underground mining workings, mechanical properties of the rock mass, changes in stress caused by the influence of neighbouring workings. Long-term prediction and estimation of workings state can be analysed with the use of numerical methods. Application of 3D numerical modelling in stability estimation of workings with complex geometry was described with the example of Crystal Caves in Wieliczka Salt Mine. Preservation of the Crystal Caves reserve is particularly important in view of their unique character and the protection of adjacent galleries which are a part of tourist attraction included in UNESCO list. A detailed 3D model of Crystal Caves and neighbouring workings was built. Application of FLAC3D modelling techniques enabled indication of the areas which are in danger of stability loss. Moreover, the area in which protective actions should be taken as well as recommendations concerning the convergence monitoring were proposed.

Abstract
The nucleus accumbens is a part of the ventral striatum along with the caudate nucleus and putamen. The role of the human nucleus accumbens in drug addiction and other psychiatric disorders is of great importance. The aim of this study was to characterize medium spiny neurons in the nucleus accumbens according to the immunohistochemical expression of GAD67.
This study was conducted on twenty human brains of both sexes between the ages of 20 and 75. The expression of GAD67 was assessed immunohistochemically, and the characterization of the neurons was based on the shape and size of the soma and the number of impregnated primary dendrites.
We showed that neurons of the human nucleus accumbens expressed GAD67 in the neuron soma and in the primary dendrites. An analysis of the cell body morphology revealed the following four different types of neurons: fusiform neurons, fusiform neurons with lateral dendrites, pyramidal neurons and multipolar neurons.
An immunohistochemical analysis showed a strong GAD67 expression in GABAergic medium spiny neurons, which could be classifi ed into four different types, and these neurons morphologically correlated with those described by the Golgi study.
What's hot about otoferlin
Authors: Avraham Karen B 
Published: November 2016

Mutations in the otoferlin (OTOF) gene lead to profound hearing loss in humans. Interestingly, a number of missense otoferlin mutations cause hearing defects but only at higher body temperature, and the reasons for this have been elusive until now. A study published in this issue of The EMBO Journal (Strenzke et al, ) adds insight into the underlying mechanisms for this heat‐dependent hearing loss.

Published: November 2016

BACKGROUND:
Low human papillomavirus (HPV) vaccination coverage is an urgent public health problem requiring action. To identify policy remedies to suboptimal HPV vaccination, we assessed the relationship between states’ school entry requirements and adolescent vaccination.

METHODS:
We gathered data on states’ school entry requirements for adolescent vaccination (tetanus, diphtheria, and pertussis [Tdap] booster; meningococcal; and HPV) from 2007 to 2012 from Immunization Action Coalition. The National Immunization Survey–Teen provided medical record–verified vaccination data for 99 921 adolescents. We calculated coverage (among 13- to 17-year-olds) for individual vaccinations and concomitant vaccination. HPV vaccination outcomes were among female adolescents. Analyses used weighted longitudinal multivariable models.

RESULTS:
States with requirements for Tdap booster and meningococcal vaccination had 22 and 24 percentage point increases in coverage for these vaccines, respectively, compared with other states (both P &lt; .05). States with HPV vaccination requirements had &lt;1 percentage point increase in coverage for this vaccine (P &lt; .05). Tdap booster and meningococcal vaccination requirements, respectively, were associated with 8 and 4 percentage point spillover increases for HPV vaccination coverage (both P &lt; .05) and with increases for concomitant vaccination (all P &lt; .05).

CONCLUSIONS:
Ensuring all states have meningococcal vaccination requirements could improve the nation’s HPV vaccination coverage, given that many states already require Tdap booster but not meningococcal vaccination for school entry. Vaccination programs and clinicians should capitalize on changes in adolescent vaccination, including concomitant vaccination, that may arise after states adopt vaccination requirements. Additional studies are needed on the effects of HPV vaccination requirements and opt-out provisions.

Published: November 2016

The safe use of recycled paper and board material for food packaging applications is a major area of investigations. Therefore, the aim of current study was to evaluate the amount of heavy metals in recycled paper pastry packages and measurement of migration over the time into pastries.
In this study, the presence of heavy metals in common confectionery packaging and effects of storage time and kind of pastry on the migration are investigated.
The results of the study indicate that harmful metals such as Pb are detected at high concentrations in most of the recycled boxes that are used for pastry packaging, and heavy metals could migrate from the recycled packages into food during usage.
It seems that the procedure of preparing recycled paperboard for food packaging should be reconsidered.

Published: November 2016

L-glutaminase (L-glutamine amidohydrolase, EC 3.5.1.2) is a very important enzyme due to its role as flavor enhancer and antileukemic agent. Salt-tolerant L-glutaminase produced bymarine bacteria is favorable in food industries. This study describes the screening of L- glutaminase producing marine bacteria from Sangihe-Talaud Sea, North Sulawesi, Indonesia.Screening of L-glutaminase was performed using a liquid medium and identification of selected isolate was performed using molecular-based 16S rDNA. Results showed that there were 7 isolates produced positive results of L-glutaminase, and one of them (II.1 isolate) produced the highest activity, i.e 147.99 U/L, equivalent to the specific activity of 62.32 U/mg. The isolate then selected for further study. Bacterial identification based on 16S rRNA sequencing has revealed that the isolate was 96% similar to Pseudomonas aeruginosa strain CG-T8. Characterization of extracellular L-glutaminase from the II.1 isolate showed that the enzyme worked optimally at temperature of 37-45 °C and pH 7. The enzyme was stable when NaCl solution was added up to 8% and began to decrease on addition of NaCl solution of 16% and 20% with relative activity of 79% and 74%, respectively. The effect of metal ions, e.g Mn2+, Mg2+, and Co2+ in the form of chloride salt, were able to increase enzyme activity, whereas the addition of other metal ions (Zn2+, Fe3+, and Ca2+) decreased the activity. The molecular weights of L-glutaminase was estimated around42 kDa and 145 kDa.
Transnacionalismo e Gnose Liminar em “As Brasíadas” (2013), de Diana Menasché
Authors: Barzotto Leoné Astride 
Published: November 2016

Este artigo faz uma análise pós-colonial do poema “As Brasíadas”, de Diana Menasché. Este poema é parte da obra Traz o esqueleto que eu ponho a carne (2013) e, por meio dele, a autora faz uma releitura, à luz da contemporaneidade, da canônica obra de Luís de Camões, Os Lusíadas. Apesar de manter a forma do épico de Camões, Menasché atualiza o discurso e revela aspectos de transnacionalismo e de gnose liminar em sua escrita. Assim, eu proponho expor que, enquanto escritora brasileira imigrante nos Estados Unidos, ela constrói uma literatura híbrida e transfronteiriça, marcada pelo trânsito de saberes interamericanos e pela proposta de uma gnose (epistemologia) liminar que revela o vínculo entre nações e práticas culturais emancipatórias.

What Explains The Equity Risk Premium In ASEAN Countries?
Authors: Kim Soo-Hyun , Villalobos Katherine 
Published: November 2016

This paper aims to mainly investigate the impact of the selected macroeconomic variables such as inflation (INF), gross domestic product (GDP), foreign direct investment (FDI) and stocks traded turn-over ratio (STTR) on equity risk premium (ERP) of six major ASEAN member countries such as Indonesia, Malaysia, Philippines, Singapore, Thailand and Vietnam. Applied methods are panel pooled regression and panel vector error correction model (VECM) through the latest version of Eviews9. In the former approach, among the selected macroeconomic variables, both INF and STTR significantly and positively affect the ERP. Both periods and years show to have fixed effects as dummy variables. One cointegration has been determined among macroeconomic variables and ERP suggesting a long term equilibrium association which led to employ Panel VECM. INF denotes a significant long-run relationship with ERP and the error correction term results suggest deviation of INF is a relevant factor but not the errors of liquidity as the STTR didn't show any significant impact in the model. Granger Casuality test suggests both INF and ERP do granger causes each other in the short run. Thus, inflation is a robust factor of ERP in two different methods while the STTR is not a robust as it shows different results.
Las Escuelas Normales universitarias y el problema educativo en Michoacán, 1917-1930
Authors: Gutiérrez López Miguel Ángel 
Published: November 2016

Las escuelas normales formaron parte del proyecto inicial de Universidad en Michoacán. Las escuelas normales se crearon en 1915 y partir de 1917 se integraron a la Universidad Michoacana, donde permanecieron hasta 1930. Su existencia enfrentó problemas derivados de la violencia y la inestabilidad política del momento. Además de la crisis económica por la que atravesaba el estado, la Universidad y las escuelas normales realizaron sus actividades en una sociedad que enfrentaba un grave rezago educativo heredado del siglo XIX. Sin embargo, a pesar de las dificultades, estas instituciones y sus miembros asumieron la responsabilidad de formar a los profesores de educación básica que tratarían de cambiar la realidad social a partir de la alfabetización.
En este artículo se hace un recuento histórico del papel desempeñado por las escuelas normales dentro del proyecto inicial de la Universidad Michoacana. Se hace referencia al establecimiento de esta institución y al lugar que ocupó la enseñanza normal, en un contexto de crisis social derivado de la agitación política de la época. También se hace alusión a los problemas educativos y al papel que ante éstos se asignó a las escuelas normales. A la par de estas referencias institucionales y del contexto social, se muestran algunos elementos para entender las características de la organización y funcionamiento académico de las escuelas normales.
Educación en movimientos populares rurales: un estado del arte
Authors: Palumbo María Mercedes 
Published: November 2016

La literatura académica sobre movimientos sociales se caracteriza por un derrotero que comenzó en las academias estadounidense y europea en las décadas del sesenta y setenta para arribar con fuerza en América Latina en las décadas del ochenta y noventa. En nuestra región, esta categoría sufre un desplazamiento semántico hacia la noción de movimiento popular a la luz de las experiencias de resistencia al neoliberalismo. Así, se abrieron nuevas líneas de indagación dentro de las cuales se destaca el área temática que trabaja la vinculación entre movimientos populares y educación, entendiendo que las prácticas políticas son inescindibles de las prácticas pedagógicas.
El presente artículo recupera particularmente las principales producciones académicas sobre movimientos populares rurales y educación elaboradas en Argentina y Brasil y las ordena en tres categorías en función del tipo de espacio-momento focalizado: las escuelas gestadas y conducidas por movimientos, el movimiento como sujeto y principio formativo, y, finalmente, los talleres creados con fines formativos sobre distintas temáticas relacionadas con la construcción política. El objetivo del artículo apunta a visibilizar un área académica novedosa y en construcción al mismo tiempo que destaca la centralidad de las experiencias educativas rurales como cita ineludible de las investigaciones en el área temática.

The first experiment is the production test and the second one is the perception test. The learners’ responses of word stress in both experimental tasks are elicited manually and analysed according to [7]</em><em> model of metrical parameters</em><em> which is used </em><em>to investigate</em><em> the acquisition of parameters of word stress production and perception by Iraqi learners</em><em>. The findings</em><em> reveal that </em><em>Iraqi EFL learners are able to reset the parameters of L2 but even though they failed in resetting all the parameters completely. Besides, the learners used more ranking level kinds of the parameters in the perception task than in the production task which may cause Iraqi learners assign wrongly the word stress placement.</em></p></div>
A Survey on Audit Free Cloud Storage via Deniable Attribute Based Encryption
Authors: Santhi P. , Thilagamani S. 
Published: November 2016

<div><p><em>Cloud computing is a rising technology which provider an assortment of opportunities for online distribution of resources or services. The most effective advantage of using cloud computing is higher availability of services with less cost and simple scalability. While the storage space of shared data on remote servers is not a new development, current development of cloud computing validates a more careful look at its actual consequences involving privacy and confidentiality issues. As users no longer actually possess the storage of their data, traditional cryptographic primitives for the purpose of data protection cannot be directly accepted. In particular, simply downloading all the data for its integrity confirmation is not a realistic explanation due to the expensiveness in I/O and transmission cost across the network. Besides, it is often not enough to detect the data corruption only when contacting the data, as it does not offer users correctness assurance for those un-accessed information and might be too late to recover the data loss or damage. To fully make sure the data integrity and save the cloud users’ calculation resources as well as online burden, it is of critical importance to allow public auditing service for cloud data, so that users may choice to an independent third party auditor (TPA) to audit the contract out data when needed. The TPA, who has expertise and abilities that users do not, can occasionally check the honesty of all the data stored in the cloud on behalf of the users, which provides a much more better and reasonable way for the users to ensure their storage rightness in the cloud. In a word, allowing public auditing services will play an important role for this emerging cloud market to become fully recognized; where users will need ways to evaluate risk and gain hope in the cloud. </em></p></div>

Abstract
Condensate banking results from a combination of factors including fluid properties, formation flow characteristics, and pressures in the formation and wellbore. The production performance may suffer provided these factors are not understood at the beginning of field development. Determining the fluid properties can be vital in any reservoir, hence it plays a crucial role in gas-condensate reservoirs where condensate/gas ratio is significant in estimates for the sales potential of gas and liquid. Once reservoir fluids enter a wellbore both temperature and pressure conditions may change, where condensate liquid can be produced into the wellbore but liquid can also drop out within the wellbore. If the liquid falls back down the wellbore, the liquid percentage will increase and may eventually restrict the production. Thus, it is very important for robust reservoir management that each and every control and uncertainty parameter is understood not only in theory but also in practice with solid examples as done in this study.
A robust commercial optimization and uncertainty software is coupled with a full-physics commercial simulator that models the phenomenon so as to investigate the significance of major parameters on performance of gas-condensate reservoirs under recycling. Control and uncertainty variables have been investigated via several simulation runs in specified ranges to represent real reservoir and performance conditions rather than theoretical assumptions.
This study aims to prepare an insight into the mechanism of gas injection process in reducing gas-well productivity losses due to condensate blockage in the near wellbore region. The main goal of this work is to investigate gas recycling into the reservoir to enhance condensate recovery. The results show the influence of each control or uncertainty variable, leading to a better understanding of management of gas-condensate reservoirs under gas recycling. Impact of fractures is significant and the tornado diagrams illustrate the relative significance of each factor.
The results and sensitivities are compared and discussed in light of a comprehensive literature review of recycling gas-condensate reservoirs with different process optimization methods. The significance of all major parameters are outlined using tornado charts to serve as a practical example for optimization of relevant future applications.
Development of Excel Based Cost Estimating Module for Process & Utility Piping and Pipelines
Authors: Emam Ahmed , AL Badi Rahma 
Published: November 2016

Abstract
This report details the process to develop excel based piping bulk parametric cost estimating module which might be used as quick standardized computer based tool to estimate process& utility piping costs for oil and gas projects executed within Abu Dhabi region. It is also useful estimating tool especially during Conceptual and FEED design stages when 3D CAD models are not available to extract detailed piping Material Takeoff's (MTO's) or in these cases when we have new project where we don't have enough historical cost data/benchmarks to use as basis to predict piping cost account based on Factoring / Lang approach.
This module can be used as powerful tool to estimate the supply and installation costs for pipes, fittings and flanges based on normal bare carbon steel material of construction or solid exotic materials like stainless steel, INCONEL 625, INCOLOY 825 and Histalloy. It can be also used to estimate the cost for lining with fusion bond epoxy (FBE), cladding with corrosion resistant alloys (CRA) and external coating with three layers of high density polypropylene (3LHDPP).
Published piping supplier's weight data tables have been analyzed and weight curves have been plotted against the key technical parameters such as pipe size/schedule and pressure rating. Curve fitting approach has been followed to extract weight parametric equations for each piping sub-commodity which have been used as reference equations to build the subject module. The same approach has been followed for installation man-hours, material supply unit rates, coating/painting unit rates, lining/cladding unit rates and all inclusive construction labor hourly as extracted from oil and gas projects executed recently within Abu Dhabi region.
This report will also describe the approach followed to benchmark the material supply/installation unit rates as estimated by this module as compared with recent awarded contractual unit rates for the same piping commodity, also benchmark on the overall project cost estimate level as compared with recent bids for the same scope.
