Agreement in human life to protect the rights and obligations are balanced. Differences in Islamic Law Perspective: Halal, agreed, able, without coercion, consent and Qobul. While the perspective of Positive Law: agree, capable, certain things, certain circumstances in accordance with Article 1320 of the Civil Code. The equation embracing principle of freedom of contract (al-Hurriyah) Islamic law is based on freedom of contract and volunteerism of each of the parties to a transaction (Q.S.An-Nisa ', 29). Give freedom to every person doing contract as desired, specify its legal consequences are religious teachings. The development of standard agreements in practice must be based on Sharia Principles provide benefits both parties, within the limits of lawful and unlawful, and the limits of public order and contract law, the provisions of Islamic law which is original. Perspective Positive Law: Principles embraced Open, gives the broadest freedom has entered into agreements contain anything, does not violate public order and morality. Rapid trade development followed the model "Standard Agreement". Business actors prepare raw clauses in the Agreement and can be accepted by the community. Raw agreements as a form of efficiency, the parties benefit and advantage to both parties.

Rebuilding Nepal for next earthquakeABSTRACTThe paper is prepared to draw attention of local and international community including the government and donors to gear up for policy reform and create an environment for investing in proactive earthquake safety initiatives before the next earthquake strikes. The paper focuses on the outcome of the author’s continuous interaction with local community since 1985 on the need for extended earthquake safety initiatives through stakeholders’ easy access to technical assistance and financial resources.  The most neglected aspect in the earthquake initiatives of Nepal is the lack of state ownership and lack of dedicated responsible institutions resulting in a massive toll of life and property. It is time to use the opportunity created by the April 2015 earthquake.Keywords: policy reform; proactive initiatives; conservation; strengthening. Reconstruyendo Nepal para el siguiente terremotoRESUMENEl documento está preparado para llamar la atención de la comunidad local e internacional, incluyendo el gobierno y los donantes, para prepararse para la reforma de políticas y crear un ambiente para invertir en iniciativas proactivas de seguridad ante terremotos antes del próximo terremoto.

Энергетические распределения и свойства занятых и свободных электронных состояний для плоского комплекса порфирина никеля NiP исследованы методами рентгеновской фотоэмиссионной и абсорбционной спектроскопии. В результате анализа экспериментальных спектров валентной фотоэмиссии определен характер и энергетические положения верхних занятых электронных состояний: высшее занятое состояние сформировано в основном атомными состояниями порфинового лиганда, следующие два состояния связаны с 3d-состояниями атома никеля. Установлено, что низшее свободное состояние имеет специфический характер и описывается b1g-МО sigma-типа, которая формируется свободными Ni3dx2-y2-состояниями и занятыми 2p-состояниями неподеленных электронных пар атомов азота. Этот специфический характер низшего свободного состояния является следствием донорно-акцепторной химической связи в NiP.

Представлены результаты исследования структурных и магнитных свойств пленок Fe87Pt13, синтезированных с использованием твердофазных реакций, и композитных пленок Fe87Pt13-Al2O3, полученных с помощью метода алюмотермии. Показано, что в синтезированных образцах обоих типов присутствует вращающаяся магнитная анизотропия, заключающаяся в том, что направление легкой оси намагничивания в плоскости пленки может устанавливаться магнитным полем. Установлено, что в композитных Fe87Pt13-Al2O3 пленках величина вращающейся магнитной анизотропии на порядок выше, чем в образцах Fe87Pt13. Сделано предположение, что природа вращающейся магнитной анизотропии связана с обменным взаимодействием L10-FePt фазы с L12-Fe3Pt фазой в пленках Fe87Pt13 и с магнитными окислами железа в образцах Fe87Pt13-Al2O3.

Published: February 2017

С помощью методов численного моделирования рассчитано температурное поле, возникающее в поверхностном слое мишени из никелида титана, содержащей включения интерметаллида NiTi2, облучаемой низкоэнергетическим сильноточным электронным пучком микросекундной длительности. Полученное температурное поле сравнивалось с температурным полем, рассчитанным ранее для мишени из нержавеющей стали 316L, содержащей включение из сульфида марганца (MnS). Обнаружено, что, как и в случае с нержавеющей сталью, в области расположения включения существует перегрев. Однако величина перегрева в случае никелида титана (12 K) существенно ниже, чем в случае нержавеющей стали 316L (283 K). Также существенно отличается динамика плавления двух систем.

Biodiversity reporting in India: a view from the top
Authors: Mansi Mansi , Pandey Rakesh , Stringer Carolyn
Published: February 2017

The purpose of this study is to explore the biodiversity reporting practices inside Indian companies. Biodiversity reporting studies across Indian companies are important because India has a wealth of biodiversity assets, that is, wildlife, flora, fauna, natural habitats, rare and endangered species and biological resources, and accounts for 7.8% of the global recorded species (Biological Diversity Act, the Biodiversity Rules, Andhra Pradesh Biodiversity Board, 2009). There are approximately 45,500 species of plants, 91,200 species of animals and 5,550 microbial species documented in India (National Biodiversity Authority, 2014). The International Union for the Conservation of Nature (IUCN) has listed 132 species of animals and plants in the Critically Endangered Category (Sudhi, 2012). To date, the literature omits to explore the biodiversity reporting practices inside Indian companies. Another important reason to conduct is this study is that India has alarming population levels; thus there is a huge demand for land, energy, and resources, which leads to massive biodiversity loss, deforestation, and habitat destruction. It is very likely that with the limited land mass and increasing population in India, several ecosystems, wildlife, flora and fauna will be/have been exploited, disturbed, and endangered. Given the high potential impact on biodiversity by industries, we are concerned that there is a dearth of biodiversity reporting studies within the Indian subcontinent. We concentrate on the largest companies (based on market capitalisation) because similar to Van Liempd and Busch (2013), we also expect that the largest companies have the greatest impact on biodiversity; therefore, they are expected to show more accountability to their stakeholders. Therefore it is worth exploring how Indian companies are engaging in biodiversity reporting practices (e.g. biodiversity conservation, biodiversity protection, habitat and ecosystem conservation); and whether these organisations are disclosing their impact(s) (both in quantity and quality) on biodiversity (such as wildlife, flora and fauna). Moreover, India has also been classified as one of 17 mega-diversity countries by The World Conservation Monitoring Centre which account for more than 70% of the planet’s species (Williams, 2001). All these reasons make this study timely and important.

Introduction/Objective. The ideal reconstruction procedure after total gastrectomy should replace all lost functions of the stomach. The aim of this study was to evaluate the usefulness of preserving the duodenal passage in subsequent improvement of body weight (BW) and body mass index (BMI) in patients with gastric cancer after total gastrectomy. Methods. A total of 30 patients with gastric cancer were prospectively randomly divided into a group of reconstruction with double-tract (n = 15) and a group of reconstruction with simple Roux-en-Y after total gastrectomy. They were stratified by sex, age, their anthropometric measurements (BW, BMI), primary tumor localization, Lauren?s classification, TNM stage classification, length of hospital stay, operation duration, postoperative complications, and mortality. Postoperatively, BW and BMI were measured at three, six, and 12 months and compared between the two groups. Results. The clinical group of double-tract patients had significantly higher the values of BW in the postoperative period after six (66.6 ? 4.9 vs. 61.7 ? 7.6; p < 0.05 paired Student?s t-test) and after 12 months (67.0 ? 4.9 vs. 62.3 ? 7.2; p < 0.05 paired Student?s t-test) compared to the group of Roux-en-Y patients. On the other hand, the clinical group of double-tract patients also had significantly higher the values of BMI in postoperative period after 12 months (23.6 ? 1.1 vs. 22.5 ? 1.6; p < 0.05 paired Student?s t-test) in relation to the Roux-en-Y group of patients. Conclusion. Reconstruction procedure carried out after total gastrectomy which implies preserving the duodenal passage has significant increase of BW and BMI, compared to reconstruction procedure without the preservation of the duodenal passage.

Rich biodiversity and equally rich cultural heritages are the two invaluable assets of most of the Third World Counties (TWC). Biogenetic resources are the primary source of valuable genes, chemicals, drugs, pharmaceuticals, natural dyes, gums, resins, enzymes or proteins of great health, nutritional and economic importance. Biodiversity regulates and maintains overall health of the life support systems on earth and is the source from which human race derives food, fodder, fuel, fibre, shelter, medicine and raw material for meeting his other multifarious needs and industrial goods required for the ever changing and ever increasing needs and aspirations. TWC members are still at the receiving end as far as the development of special value added products and herbal technologies are concerned. The developed countries, on the other hand, are emerging as super powers with their biotechnological strength. IPRs emerged strongly during the industrial revolution and it has been an important driving force behind rapid industrial growth and prosperity of the Western countries during the last 3 centuries. Nowadays Access and Benefit Sharing issues have become a central theme for subsequent detailed discussions and decision making under CBD, TRIPS and the WIPO. It is therefore increasingly urgent for the CBD to make ABS work as was intended. The entry into force of the Nagoya Protocol represents a step in this direction. In India, we can be proud of having the distinction of the first country in experimenting a benefit-sharing model that implemented in Letter and Spirit Article 8(j) of CBD.

Especially young individuals are grown up under the influence of those platforms such as computers, television, mobile phones, and tablet pc. On the contrary to the generally known game addictiveness, it is a motivating instrument which develops their imaginary. Digital games are the virtual environments where their imagination develops. Digital games are the virtual environments where people form an interaction with computers or each other through a program. The player may play games against the computer by himself as well as he may play against other people in any region of the world. As seen in every field, advertising has also found a wide publicity in this field. In this study, the advergames and their interactions with game advertisement narration will be discussed.
Drug-Induced Serotonin Syndrome
Authors: Bartlett Dana
Published: February 2017

Serotonin syndrome is a potentially fatal condition caused by drugs that affect serotonin metabolism or act as serotonin receptor agonists. Monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, and serotonin-norepinephrine reuptake inhibitors are the medications most commonly associated with serotonin syndrome. Serotonin syndrome can be mild and of short duration, but a prolonged course, life-threatening complications, and death are possible. Detection of serotonin syndrome is not difficult if the diagnostic criteria are understood and properly used, but the syndrome has no confirmatory tests and other drug-induced syndromes can, to a degree, mimic serotonin syndrome. The treatment is symptomatic and supportive. Antidotal therapies are available, but the evidence for their effectiveness is limited. If serotonin syndrome is promptly identified and aggressively treated, the patient should fully recover.
The impact of optic nerve movement on optic nerve magnetic resonance diffusion parameters
Authors: Moodley Anand , Rae William I.D. , Brijmohan Yarish , Durand Miranda , Connolly Catherine , Michowicz Andrew , Bhigjee Ahmed
Published: February 2017

Background: Optic nerve diffusion imaging is a useful investigational tool of optic nerve microstructure, but is limited by eye-movement-induced optic nerve movement and artifacts from surrounding cerebrospinal fluid, fat, bone and air. Attempts at improving patient cooperation, thus voluntarily limiting eye movement during a standard diffusion imagingsequence, are usually futile. The aim of this study was to establish the impact of optic nerve movement on clinical diffusion parameters of the optic nerve.Method: Twenty-nine healthy volunteers with intact vision and intact conjugate gaze were recruited and subjected to magnetic resonance diffusion-weighted imaging (DWI) and diffusion-tensor imaging (DTI) of the optic nerves. Twenty right eyes had nerve tracking done using single-shot echo-planar imaging at 20 time points over 3 minutes. Optic nerve movement measurements were correlated with diffusion parameters of apparent diffusion coefficient (ADC), mean diffusivity (MD), fractional anisotropy (FA) and anisotropic index(AI) using Spearman’s rank correlation.Results: No significant correlations were noted between optic nerve movement parameters and ADC in the axial plane and MD of the optic nerve. Low to moderate negative correlations were noted between optic nerve movement parameters and AI and FA and positive correlation with ADC in the radial plane.Conclusion: Optic nerve movement documented during the timespan of standard diffusion sequences (DWI and DTI) has a negative effect on the anisotropic diffusion parameters of the optic nerve. With greater eye movement, optic nerve diffusion appears less anisotropic owing to greater radial diffusion.
Thoracic cage injury imaging in rugby players
Authors: De Villiers Richard
Published: February 2017

Rugby players often sustain high-impact collisions and are therefore at risk of significant traumatic thoracic injuries. Injury to the thoracic cage may be associated with potentially life-threatening sequelae. Player management is often based on the accuracy of the imaging report. The author suggests a combination of computed tomography and magnetic resonance imaging to optimally evaluate the full spectrum of these potentially serious injuries.

Leveraging the Value of Human Relationships to Improve Health Outcomes
Authors: Kasthurirathne Suranga , Mamlin Burke , Cullen Theresa
Published: February 2017

Objectives: Despite significant awareness on the value of leveraging patient relationships across the healthcare continuum, there is no research on the potential of using Electronic Health Record (EHR) systems to store structured patient relationship data, or its impact on enabling better health-care. We sought to identify which EHR systems supported effective patient relationship data collection, and for systems that do, what types of relationship data is collected, how this data is used, and the perceived value of doing so.

Materials and methods: We performed a literature search to identify EHR systems that supported patient relationship data collection. Based on our results, we defined attributes of an effective patient relationship model. The Open Medical Record System (OpenMRS), an open source medical record platform for underserved settings met our eligibility criteria for effective patient relationship collection. We performed a survey to understand how the OpenMRS patient relationship model was used, and how it brought value to implementers.

Results: The OpenMRS patient relationship model has won widespread adoption across many implementations and is perceived to be valuable in enabling better health care delivery. Patient relationship information is widely used for community health programs and enabling chronic care. Additionally, many OpenMRS implementers were using this feature to collect custom relationship types for implementation specific needs.

Conclusions: We believe that flexible patient relationship data collection is critical for better healthcare, and can inform community care and chronic care initiatives across the world. Additionally, patient relationship data could also be leveraged for many other initiatives such as patient centric care and in the field of precision medicine.
An Effective Branch-and-cut algorithm in Order to Solve the Mixed Integer Bi-level Programming
Authors: Rahmani Arsalan , Yousefikhoshbakht Majid
Published: February 2017

In this paper, a new branch-and-cut algorithm for mixed integer bi-level programming is proposed. For achieving this purpose, a historical perspective of the development of enumeration methods in the field of bi-level linear programming is considered. Then, we present some obstacles for using branch and bound method based on them, and an algorithm is developed to solve for mixed integer bi-level problem. Finally, we use a preference function to determine the choice of branching and specialized cuts in a branch and cut tree. Computational results are reported and compared favorably to those of previous methods and then implications discussed. The results show that not only the proposed algorithm can find high quality solutions for solving a number of the problems, but also it is competitive with other famous published algorithms.

Espiritualidade e saúde: a experiência grega arcaica
Authors: Possebon Fábricio
Published: February 2017

O estudo do vocabulário grego arcaico, apoiado em passagens dos textos épicos, nos permite construir um modelo de constituição do ser. O homem, ánthropos, seria então um ser pluridimensional, formado por diversos corpos ou envoltórios: o físico (sôma), o vital (pneûma), o emocional (thymós) e o mental (noûs). Os corpos abrigariam a essência, ou seja, a alma (psykhé). Nossa hipótese é que os sistemas modernos pluridimensionais têm como base o sistema grego, modernamente enriquecido com a contribuição do saber oriental. Espiritualidade é aqui entendida como a busca pela psykhé, caminho que passa pela harmonia dos envoltórios. O estado de desarmonia é a doença e a saúde é o perfeito equilíbrio.

Review on penetration and transport phenomena in porous media during slot die coating
Authors: Ding Xiaoyu , Harris Tequila A. L.
Published: February 2017

A distinctive field in the coatings industry is coating of porous media, which has broad applications including paper, textiles, electronics, filtration, and energy sectors. Fluid penetration is an important issue during direct coating of a liquid bead on porous media, which is driven by the pressure from an external flow field and the surface tension in the porous media. Generally, during the coating process, some level of penetration is desirable to obtain specific material properties, but inadequate or excessive penetration is detrimental. To help control the level of penetration, understanding relationships between operating parameters and penetration are highly desirable. In this article, the current state of academic research on modeling penetration in porous media during common coating processes, especially the slot die coating process, is reviewed. Specifically, the challenges, basic ideas, advantages, and disadvantages of macroscale, microscale, and pore‐network models on penetration in porous media are discussed. This article concludes with some recommendations for future work. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2017, 55, 1669–1680
Caste, Class, and Capital

For millions of poor people in the developing world, economic growth offers prospects for improved well-being. But what are the political and social conditions conducive to growth-oriented policies in poor democracies? This book addresses this highly consequential question by focusing on a specific empirical puzzle - policy variation across Indian states in the competition for private industrial investment, a phenomenon that came to the fore after the country adopted market reforms in 1991. Through the analysis of investment policies, this book offers a novel explanation, which links social identity, class, and economic policy outcomes. Its main findings highlight a link between pro-business policies and exclusionary political trends in India's high growth phase, and offer a sobering perspective on the current model of growth in the country. It adds to our understanding of Indian political economy as well as to the dynamics of economic development in poor democracies.
Alternative realities: Explaining security in the Asia-Pacific
Authors: Beeson Mark
Published: February 2017

The central argument of this article is that constructivists in particular underestimate or even ignore the importance of the ‘real’ structural inheritance that shapes state (and the political elites that represent them) behaviour. Even though the future is indeterminate, some outcomes are decidedly more likely than others, especially where policymakers believe they inhabit a strategic universe of zero sum outcomes and where self-reliance and assertion remain important. I suggest that ‘critical realism’ offers a way of accounting for the institutional structures that shape international behaviour. The first half of this article makes the case for a critical realist approach. The second half illustrates the possible importance of this claim with reference to the contemporary geopolitics of the Asia-Pacific region.
SEMIPARAMETRIC EFFICIENCY FOR CENSORED LINEAR REGRESSION MODELS WITH HETEROSKEDASTIC ERRORS
Authors: Chen Tao
Published: February 2017

Using a simplified approach developed by Severini and Tripathi (2001), we calculate the semiparametric efficiency bound for the finite-dimensional parameters of censored linear regression models with heteroskedastic errors. Under an additional identification at infinity type assumption, we propose an efficient estimator based on a novel result from Lewbel and Linton (2002). An extension to censored partially linear single-index models is also presented.
Testis-specific transcriptional regulators selectively occupy BORIS-bound CTCF target regions in mouse male germ cells

Published: February 2017

Despite sharing the same sequence specificity in vitro and in vivo, CCCTC-binding factor (CTCF) and its paralog brother of the regulator of imprinted sites (BORIS) are simultaneously expressed in germ cells. Recently, ChIP-seq analysis revealed two classes of CTCF/BORIS-bound regions: single CTCF target sites (1xCTSes) that are bound by CTCF alone (CTCF-only) or double CTCF target sites (2xCTSes) simultaneously bound by CTCF and BORIS (CTCF&BORIS) or BORIS alone (BORIS-only) in germ cells and in BORIS-positive somatic cancer cells. BORIS-bound regions (CTCF&BORIS and BORIS-only sites) are, on average, enriched for RNA polymerase II (RNAPII) binding and histone retention in mature spermatozoa relative to CTCF-only sites, but little else is known about them. We show that subsets of CTCF&BORIS and BORIS-only sites are occupied by several testis-specific transcriptional regulators (TSTRs) and associated with highly expressed germ cell-specific genes and histone retention in mature spermatozoa. We also demonstrate a physical interaction between BORIS and one of the analyzed TSTRs, TATA-binding protein (TBP)-associated factor 7-like (TAF7L). Our data suggest that CTCF and BORIS cooperate with additional TSTRs to regulate gene expression in developing male gametes and histone retention in mature spermatozoa, potentially priming certain regions of the genome for rapid activation following fertilization.

Oligodendrocyte precursor cells (OPCs) have the ability to repair demyelinated lesions by maturing into myelin-producing oligodendrocytes. Recent evidence suggests that miR-219 helps regulate the differentiation of OPCs into oligodendrocytes. We performed oligodendrocyte differentiation studies using miR-219-overexpressing mouse embryonic stem cells (miR219-mESCs). The self-renewal and multiple differentiation properties of miR219-mESCs were analyzed by the expression of the stage-specific cell markers Nanog, Oct4, nestin, musashi1, GFAP, Tuj1 and O4. MiR-219 accelerated the differentiation of mESC-derived neural precursor cells (NPCs) into OPCs. We further transplanted OPCs derived from miR219-mESCs (miR219-OPCs) into cuprizone-induced chronically demyelinated mice to observe remyelination, which resulted in well-contained oligodendrocyte grafts that migrated along the corpus callosum and matured to express myelin basic protein (MBP). Ultrastructural studies further confirmed the presence of new myelin sheaths. Improved cognitive function in these mice was confirmed by behavioral tests. Importantly, the transplanted miR219-OPCs induced the proliferation of endogenous NPCs. In conclusion, these data demonstrate that miR-219 rapidly transforms mESCs into oligodendrocyte lineage cells and that the transplantation of miR219-OPCs not only promotes remyelination and improves cognitive function but also enhances the proliferation of host endogenous NPCs following chronic demyelination. These results support the potential of a therapeutic role for miR-219 in demyelinating diseases.
Proposed manipulation of spin currents in GaAs crystal using the Pockels effect
Authors: Zhang Xingchu
Published: February 2017

A spin current could induce linear electro-optical electric susceptibility, thus the incident light could interact with the spin current via Pockels effect. In this letter, we find by appropriately selecting the directions of the applied electric field, the propagation direction of the incident light and its polarization, there will exist spin angular momentum transfer between the incident light and the spin polarized electrons resulting in the change of the spin current. Basing on this, a method for manipulating spin current is put forward. In our method, we could adjust the magnitude of the applied electric field or the intensity of incident light to manipulate the spin currents. The numerical results show that, for the condition of the applied electric field being 1×103 Vm-1 and the intensity of incident light being 1×105 Wm-2, the ratio of the changed pure spin current versus initial pure spin current will drop to 0.1%, and the spin polarization of the generated spin-polarized current will reach to 99.9%.
Feminism Against Neoliberalism: Theorising Biopolitics in Germany, 1978–1993
Authors: Loveland Kristen
Published: February 2017

Recent scholars have argued that feminism is the handmaiden of neoliberalism. This article suggests otherwise, offering a study of West German feminists in the 1980s. Responding to the advent of reproductive technologies, these feminists were pioneers in critically assessing the relationship between reproduction and neoliberalism. Radical feminists like Maria Mies argued that global capitalism allied with the state to coercively structure reproduction for its needs. For disability rights feminists like Theresia Degener, however, the state did not coerce; it produced citizens who willingly regulated their reproduction under a new eugenics from below. In analysing the marketisation of reproduction, German feminists developed a more sophisticated understanding of neoliberalism than critics today who simplistically theorise neoliberalism as the mere retraction of the state.
