Tuning noise in gene expression
Authors: Tyagi Sanjay 
Published: May 2015

The relative contribution of promoter architecture and the associated chromatin environment in regulating gene expression noise has remained elusive. In their recent work, Arkin, Schaffer and colleagues (Dey et al, 2015) show that mean expression and noise for a given promoter at different genomic loci are uncorrelated and influenced by the local chromatin environment.

Published: May 2015

<p>Las raíces almacenadoras de yuca representan una fuente importante de almidón. La ruta metabólica del almidón ha sido reconstruida recientemente en yuca gracias a la liberación de la secuencia completa de su genoma. En este estudio se evaluó la expresión de los genes que codifican para las enzimas Pululanasa, Isoamilasa, α-amilasa, Enzima Desproporcionante, ADP-glucosa pirofoforilasa, Almidón sintasa unida al gránulo, Enzima ramificante del almidón y Sintasa soluble del almidón, en las raíces almacenadoras de plantas de 5 y 11 meses de edad, en un grupo de cinco variedades de yuca. Se evidenciaron diferencias importantes en la expresión de estos genes entre las variedades evaluadas y entre los dos tiempos. Las variedades CM523-7 y SM1219-2 presentaron uno de los niveles más altos de expresión para los genes ADP-glucosa pirofoforilasa y Almidón sintasa unida al gránulo mientras que el gen para α-amilasa fue el más bajo en estas dos variedades. Aunque la variedad TMS60444 presentó niveles de expresión similares en genes implicados en la síntesis de almidón, fue la que presentó el mayor nivel de expresión de la α-amilasa. Estos datos se pueden correlacionar con el relativo bajo contenido de materia seca en esta variedad. Los datos de expresión génica presentados en este trabajo permitirán complementar información sobre actividad enzimática con miras a identificar los elementos más importantes en la acumulación diferencial de almidón entre variedades de yuca.</p><p><strong>ABSTRACT</strong></p><p>Cassava storage roots represent an important starch source. Recently, the starch metabolic pathway in cassava has been reconstructed thanks to the full release of its genome. In this study gene expression was evaluated for genes coding Pullulanase, Isoamylase, α-amylase, Deproportionating enzyme, ADP-glucose pyrophosphorylase, Granule bound starch synthase, Starch branching enzyme and Soluble starch synthase, in cassava storage roots 5 and 11 months old, in 5 cassava varieties. Important gene expression differences were detected both at the variety and time level. CM523-7 and SM1219-2 showed one of the highest expression levels for AGPase and GBSS genes, while α-amylase showed the lowest level in these two varieties. TMS60444 variety showed similar expression levels in starch biosynthesis-related genes, but conversely also showed the highest α-amylase expression. This correlates with the relative low dry-matter content in TMS60444. Gene expression data reported here will allow complementing actual information on enzymatic activity, in order to identify the most relevant factors in differential starch accumulation between cassava varieties.</p><br /><p> </p>

Charge Compensation in Trivalent Doped Ca3(SiO4)Cl2
Authors: Gilbert M. R. 
Published: May 2015

ABSTRACTCalcium chlorosilicate (Ca3(SiO4)Cl2) is seen as a potential host phase for the immobilization of Cl-rich wastes arising from pyrochemical reprocessing, a waste stream often containing a mix of both di- and trivalent cations. Substitution of trivalent cations into the lattice requires some form of charge compensation to ensure the lattice remains charge neutral overall. Whilst previous work has only examined this through the formation of Ca vacancies, this study investigates the feasibility of charge-balancing via the substitution of a monovalent cation onto the Ca sites of the lattice. To that end, a series of static lattice calculations were performed to determine the site selectivity of monovalent cations of differing size when substituted onto the Ca sites of the calcium chlorosilicate lattice and the solution energies for the overall substitution processes compared with those for charge compensation via vacancy formation. In all cases the monovalent charge-balancing species shows a clear preference for substitution onto the Ca1 site in the calcium chlorosilicate lattice. The solution energy of the substitution process increases with the increasing ionic radii of both the mono- and trivalent species as the steric stresses associated with substitution of larger cations than the Ca2+ host increase. As such, only charge-balancing using Li+, Na+ or K+ is more favourable than via formation of a Ca vacancy.
Xps Study Of Aisi 316L Ss Surfaces After Mechanical And Electrochemical Polishing and Chelating/Electro-Chelating Treatments
Authors: Rokosz K. , Hryniewicz T. 
Published: May 2015

ABSTRACT
In the paper, there are presented the analyses of iron Fe2p3/2 and chromium Cr2p3/2 and oxide O1s XPS spectra of surfaces obtained after abrasive and electrochemical polishing with additional treatment as chemical chelating in the solution containing of 10% Citric Acid and 2% Ethylenediaminetetraacetic Acid. There was also performed electro-chelating after mechanical polishing in the electrolyte for chemical chelating. The maximum values of chromium compounds to iron compounds ratio were obtained after electropolishing with and without stirring with chemical chelating in Citric Acid and EDTA and they were in rage from 3.5 to 3.6. The minimum value was obtained for the steel surface after abrasive polishing and electro-chelating and was equal 1.3. After electrochemical polishing and chemical passivation in the surface layer there were detected FeO and Cr(OH)3 as dominated compounds. After abrasive polishing and electro-chelating there were mostly Fe2O3 and Cr2O3.
Rationalisation of Austenite Transformation to Upper or Lower Bainite in Steels
Authors: Ławrynowicz Z. 
Published: May 2015

Abstract
The paper presents an analytical evaluation of transition temperature from upper to lower bainite in Fe-C-Cr steel. The calculations was based on the model constructed by Matas and Hehemann which involves a comparison between the times needed to precipitate cementite within the bainitic ferrite plates (tθ), with the time required to decarburise supersaturated ferrite plates (td). The transition between upper and lower bainite is found to occur over a narrow range of temperatures (350-410°C) and depends on the thickness of bainitic ferrite laths and the volume fraction of precipitated cementite. On comparing the td and tθ times it was found that the transition temperature from upper to lower bainite reaction (LS) of about 350oC could be predicted if the thickness of bainitic ferrite laths is set as wo = 0.1 μm and volume fraction of cementite is set as ξ = 0.01
Biomaterials and Implants in Cardiac and Vascular Surgery - Review
Authors: Stanisławska A. 
Published: May 2015

Abstract
Currently, on prosthesis in cardiac blood vessels and heart valves are used materials of animal or synthetic origin. For animal materials include, among others pericardial sac in which is the heart. Materials such as this (natural) are characterized by a remarkable biocompatibility within the human body, but their main disadvantage is the relatively low durability. In turn, synthetic materials, which include the austenitic chromium-nickel-molybdenum steels, alloys with a shape memory (nickel-titanium), or polymeric materials, such as lactic acid, are characterized by high stability in an environment of bodily fluids, wherein the insufficiently high biocompatibility with the organism human requires from patients using after implantation, anticoagulants which prevent anti-platelet deposition on the surface of the prosthesis. The present work is a review of biomaterials using in implantology and implants using in cardiac and vascular surgery.
Nanoindentation Studies of TNZ and Ti2448 Biomaterials After Magnetoelectropolishing
Authors: Hryniewicz T. , Rokosz K. , Rokicki R. , Prima F. 
Published: May 2015

Abstract
This work presents the nanoindentation results of two newly developed titanium alloy biomaterials, TNZ and Ti2448, after different surface treatments. The investigations were performed on the samples, AR – as received, MP – after abrasive polishing, EP – after a standard electropolshing, and MEP – after magnetoelectropolishing. The electropolishing processes, both EP and MEP, were conducted in the same proprietary electrolyte based on concentrated sulfuric acid. The mechanical properties of the titanium alloys biomaterials demonstrated an evident dependence on the surface treatment method, with MEP samples revealing extremely different behaviour and mechanical properties. Such a different mechanical behaviour may mean completely different composition and thickness of the surface film formed on the studied samples after MEP
Electrochemical Characterization of Gelatine Derived Ceramics
Authors: Nowak A.P. , Trzciński K. , Lisowska-Oleksiak A. 
Published: May 2015

Abstract
New materials obtained by pyrolysis of gelatine (G) and poly(1,2-dimethylsilazane) (PSN) (weight ratio: G/PSN 70/30) at temperatures 700 and 900 °C were characterized by SEM and Raman spectroscopy. The presence of ceramics influences on the cluster size of the materials. Electrochemical tests were performed by cyclic voltammetry and galvanostatic cyclic polarization. The capacity of G/PSN was 464 and 527 mAh/g for materials pyrolysed at 700 and 900 °C. The capacity fading was 1 % after 17th cycle for G/PSN at 900 °C. This value is higher of 185 mAh/g in comparison to capacity of gelatine pyrolysed at the same conditions.
Analysis of governance systems applied in multifunctional forest management in selected European mountain regions / Analýza systémov governancie využívaných pri multifunkčnom manažmente lesov vo vybraných európskych horských oblastiach

Published: May 2015

Abstract
The objective of this study is to map and analyse governance systems relevant for the implementation of multifunctional mountain forest management in selected European countries. This paper is based on the FP7 research project Advanced multifunctional forest management in European mountain ranges (ARANGE). Current governance systems relevant for the implementation of multifunctional forest management are analysed in seven case study areas: the Iberian Mountains (Spain), Western Alps (France), Eastern Alps (Austria), Dinaric Mountains (Slovenia), Scandinavian Mountains (Sweden), Western Carpathians (Slovakia) and Western Rhodopes (Bulgaria). Qualitative social research methods were applied for data collection. Semi-structured questionnaire was focused on the following elements of governance: participation and stakeholders interactions and inter-sectorial coordination. The results indicate that forest managers share a general perception of multifunctional forest management being focused on preserving or strengthening several forest functions and services including timber production. They believe that current governance systems basically support multifunctional management of mountain forests. The participatory and inter-sectoral processes are playing an important role in multifunctional forest management in selected European mountain regions.
Použiteľnosť elektronických pomôcok pre buzolové meranie v lesníckom mapovaní a výskume

Published: May 2015

Abstract
The paper contains output of the research aimed on applicability of compass measurement using laser range-finder Impulse LR 200 and electronic compass LTI MapStar Compass Module in forestry mapping and research. The research was aimed on the impact of measurement methods and also methods of computation on the final precision of the position evaluation. Because the combination of instruments, with the Field-Map software, is also used in forestry research (forest inventory, research of natural forests), the paper shows also the methods of evaluation referring to this field of use of compass measurement. In dependence to measurement and evaluation methods there is a quite wide interval of mean position error mxy values (0.15 - 0.60 m). In general it can be stated, that compass measurement in areas without negative effects on the natural magnetism is applicable method for the under-canopy forestry mapping and research. The best of output values have shown the theoretical possibility of use in forest area cadastral mapping (4th accuracy class), especially in combination with other measurement methods

IDEAS in AGORA: Decision-Making Risk: The Difference Between Risk And Uncertainity In Economic Activities
Authors: Vasilcovschi Nicoleta , Munteanu Gabriela 
Published: May 2015

Abstract
Economic activities are always supposed to carry with them the risk of market. Our area of research is concerned with what is known as the model of risk decisions at the level of economic activity; a model that can be valuable at any point of economic development. In our research, we present important aspects of risk in taking decisions in the previous and current dynamics of the market. The conditions of taking decisions with potential risks provide decision-makers with the possibility to analyze and calculate risk in order to know what can be gained and lost. In our paper, we present a short description of a different model of risk in economic activity and of decision-making risk, providing examples that have been offered by various authors. For example, Friedman and Savage present the utility function of an economic agent and its availability to accept the risk, while Markowitz defines utility in terms of winning or losing. Our paper starts with a presentation of the quantification of risk in economic activity. In the second part, we present a model of decision-making risk that is applied in economic activities and the difference between risk and uncertainty.

Abstract
In the last decade, the financial underground markets evolved in a surprisingly way, around the world. Eastern Europe is a significant region, where illegal activities associated with the shadow economy became a real problem that affects the governments stability, the economical, political and social status. Due to the influence of old regimes and the current tolerance of the Eastern European nations, this underground corridors emphasize the risk of interfering with the financing platforms of international terrorism or organized crime

Mireille Calle-Gruber is not only a university professor and a writer, but also a leading scholar and critic of French literature and contemporary Francophone literature. Her works on Michel Butor, Claude Simon, Assia Djebar, Derrida and other contemporary writers (as well as those dealing with the history of the twentieth century literature) fill gaps in the contemporary literary history of the twentieth century. Her books not only scrutinize and analyze the writing of Claude Simon; they also shed new light on the analysis of the novel and autobiography in contemporary literature, through the memory of experience and perception
ESEJ
Authors: Mikušiak Marek 
Published: May 2015

Abstract
The aim of this paper is to clarify some important features of a specific text genre called essay. There are discussed some strategies according to which we might successfully write and read the essays, instead of analysing a general concept of essay and traditional searching for the necessary and sufficient features. In this contribution the term of essay is divided into two categories named „academic essay” and „classic essay”. T he main part of this paper focuses on the classic essay that is explained by the triangle whose vertices are represented by „factuality”, „authenticity” and „literariness”. It is demonstrated that in this case we might criticise weakened coherence of the text, but just with the regard to the classic essay as a compromise between truth and elegance.
Individual and Property Rights from the Islamic Perspective
Authors: Bhat Ali Mohammad 
Published: May 2015

AbstractThe implicit requirements in the Islamic concept of human rights stem particularly from the right to life (individual rights), forced labour, the right to property, freedom of speech, etc. Human rights in early civilizations were composites of various philosophies that served a people’s social and cultural contexts. Both religious and secular conceptions of civilization determined the laws that dictated early human rights. In the wake of World War II, the United Nations General Assembly compiled and adopted a document called The Universal Declaration of Human Rights (UDHR). The day of its adoption, 10 December 1948, became known internationally as “Human Rights Day.” But the declaration could do little to actually prevent widespread violations of human rights throughout the world. Millions of people had inviolable rights as humans but died as the result of inhumane actions. Western civilizations and societies addressed the question of human rights but did so with great variation in application and entitlement. At present, with over 30 million human beings enslaved and the majority of them women and children, we cannot afford to ignore this issue. But an impoverished country is not the only culprit - nor is Asia, although the Pacific Rim is the most heavily enslaved areas on the globe. In America itself, trafficking is the third highest source of commercial profit, with more than 300,000 people enslaved today. And America partakes both in import and export of the slave network, with 14,000 people trafficked into the country each year. The history of human rights is a long examination of the question of what is “natural and right” about the human condition. Human rights, broadly speaking, should be unchallengeable and universal. This article deals with the need to highlight the value, importance of rights, and dignity of human beings from the Islamic perspective. The individual and property rights protected in Islam have no match at present either. Respect for human beings can be realized with the call “anyone who freed a slave will find his place in gardens of heaven.” Then companions of Prophet Muhammad (pbuh) took up the challenge and did all they could for the liberty of slaves. The Pious Caliphs did every thing for the protection of human rights.
Postmodernism and Islam: Epistemological Challenges and Sociopolitical Perils
Authors: Bazzi Emad 
Published: May 2015

AbstractPostmodernism is sometimes described as an intellectual position that is congenial to a sanctioning of a pluralistic epistemology and a tolerant and inclusive society. This outlook is supposed to extend to religious methodologies and communities of faith. This seems to be a superficial view, however, in that postmodernism’s questioning of modernity’s intellectual premises does not translate into a sympathetic outlook toward religion, Islam in particular, since postmodernism opposes foundational systems of thought and Islam qualifies as a worldview that bases its epistemology on foundations, which it considers objective and universal. Nor is the situation better in the sociopolitical field since postmodernism’s theoretical decentering of the West remains just that, while in reality the modernist project goes on unchecked, its hegemony exacerbated, and its consumerist lifestyle proliferating at an unprecedented rate with the onset of globalization. It is this last aspect that is more perilous to religious worldviews since it is ultimately the availability and allure of various lifestyles and tastes, of which Western culture has a dominant share, that ultimately threaten religious convictions, more so than the deconstruction of the theoretical premises of a particular system of faith.
