Potassium catalyzed hydrogasification of low-rank coal for synthetic natural gas production
Authors: Skodras Georgios , Panagiotidou Sofia , Kokorotsikos Paris , Serafidou Maria 
Published: April 2016

AbstractPotassium catalyzed isothermal coal hydrogasification was investigated, as an alternative route for synthetic natural gas production. Potassium chemisorption occurred on oxygen sites in the coal structure and was strongly affected by the solution pH and followed the Cation Exchange Capability (CEC) which is also pH-dependent. A quadratic function described the relation between the solution pH and the fraction of the chemisorbed potassium, while; the cumulative distribution function of two Weibull probability density functions correlated the solution pH with the CEC that was linearly correlated with the fraction of the chemisorbed potassium. Coal hydrogasification is strongly affected by the increased alkalinity of the impregnating solution and increased methane yields were obtained while carbon conversion was slightly affected. This was attributed to the formation of profuse K+ substituted active sites that decompose under H2 attacks and trigger scission of the aromatic rings followed by K+ migration to neighboring complexes, thus, the hydrogasification reaction continuous to yield CH4, as codified in a three stage reaction mechanism. The relative specific hydrogasification rate was found to increase linearly with the CEC of the coal samples, suggesting that the oxygen functional groups, on which potassium is chemisorbed, act as “active sites” and are linked with the carbon’s reactivity.

Published: April 2016

Abstract
A compact dual-band asymmetric coplanar strip (ACS) fed printed monopole omnidirectional antenna with three radiating structures for 2.4/5 GHz WLAN/Bluetooth applications is presented. The designed antenna comprises of a simple ACS-fed (Asymmetric Coplanar Strip) monopole and three different strip radiating elements. It occupies a very compact overall size of 15×24 mm2 including the ground plane, which is only about 0.12 λ×0.20 λ (λ is the wavelength at the frequency of 2.45 GHz in free space). So, it has the characteristics of miniaturization. A resonant mode at 2.45 GHz is created by adding a inverted-L branch, and the resonant mode at 5.62 GHz is co-produced by the horizontal strip and vertical strip including an element which is like a Chinese Tai Chi fish. Dual desired resonant frequencies achieved, and each of them can be tuned independently. Both the simulated and measured results show reasonable agreement, and the measured dates show that the antenna has an impedance bandwidth of 90 MHz (2.4–2.49 GHz) and 810 MHz (5.07–5.88 GHz), and a reflection coefficient of less than –10 dB, it is suitable for WLAN 2.4/5.2/5.8 GHz applications and 2.4 GHz Bluetooth bands.
An Accurate Method for Measuring Airplane-Borne Conformal Antenna’s Radar Cross Section
Authors: Guo Shuxia , Zhang Lei , Wang Yafeng , Hu Chufeng 
Published: April 2016

AbstractThe airplane-borne conformal antenna attaches itself tightly with the airplane skin, so the conventional measurement method cannot determine the contribution of the airplane-borne conformal antenna to its radar cross section (RCS). This paper uses the 2D microwave imaging to isolate and extract the distribution of the reflectivity of the airplane-borne conformal antenna. It obtains the 2D spatial spectra of the conformal antenna through the wave spectral transform between the 2D spatial image and the 2D spatial spectrum. After the interpolation from the rectangular coordinate domain to the polar coordinate domain, the spectral domain data for the variation of the scatter of the conformal antenna with frequency and angle is obtained. The experimental results show that the measurement method proposed in this paper greatly enhances the airplane-borne conformal antenna’s RCS measurement accuracy, essentially eliminates the influences caused by the airplane skin and more accurately reveals the airplane-borne conformal antenna’s RCS scatter properties.

AbstractVaspin (VASP) is a protein detected in pre- and mature adipocytes, the production and secretion of which may be conditioned by nutrition status. VASP may also play a role in the regulation of food intake. Since to date, there are no available studies on serum vaspin concentrations in patients with anorexia nervosa (AN), the aim of our study is to assess serum vaspin concentrations in girls with AN in comparison to healthy subjects and determine its relationship with body weight, body masss index (BMI) and insulin.In this cross-sectional study vaspin serum concentrations were evaluated using a commercially available ELISA kit in 47 Polish girls hospitalized due to restrictive AN and 39 healthy controls (H).The mean serum concentration of VASP in girls with AN was significantly higher than in the H group. These differences were also noted after adjustment for body masss index-standard deviation score (BMI-SDS), the homeostatic model assessment-insulin resistance (HOMA-IR) index and insulin levels. There were no statistically significant correlations between the serum concentrations of VASP and body mass, BMI, BMI-SDS, insulin and HOMA-IR in the AN or healthy group.Serum vaspin levels in lean subjects are regulated in different mechanisms than previously reported in obesity. It should be established if elevated serum vaspin levels in girls with AN may contribute to low food intake in these patients.
International Assistance and National and Individual Contributions in the Development of Education for Library, Information and Archival Studies: Some Evidence from a Case Study
Authors: Johnson Ian M. 
Published: April 2016

AbstractThis is a very brief summary of a study that focused on the development of education for library, archive, and information services (LIS) in Iraq, where significant progress seemed to have been made before the Second Gulf War, despite the country’s increasing economic problems and political isolation in the last decades of the twentieth century. It drew evidence from the published literature, previously unexplored archival material, and discussions with some of the participants. The study examined professional education for librarianship, documentation, information and archives work against the background not only of the evolution of LIS, but also in the broader context of the country’s national, economic, and social development. It examined trends in international assistance for library development, and briefly reviewed parallel developments in other Arab countries to provide a benchmark.Based on this wide ranging examination, it drew some tentative conclusions about the issues that fostered the development of LIS education in Iraq, including: the attitude of government and university officials; the organisation and allocation of state finance; the development of literacy and the education system; the duration and nature of external support; the activities of foreign experts; the development of the cadre of teachers of LIS; the role played by advocacy and opportunism. The study also identified a number of factors that have held back development, including: the pressures on the state budget; the absence of a comprehensive government strategic plan to develop a culture of reading and independent learning; and a lack of flexibility in the management of the state education system.An understanding of these factors, and the approach to identifying them, may contribute to strengthening the foundations of LIS education in both developing countries and those that have an established infrastructure.

Methods of Assessing Noise Nuisance of Real Estate Surroundings
Authors: Szopińska Kinga , Krajewska Małgorzata 
Published: April 2016

Abstract
Testing what factors create the market value of real estate is key information when preparing property valuations as well as other opinions and professional evaluations on the basis of which court verdicts or administrative decisions are made. One of the factors influencing the value of some real estate is the level of noise present in the surroundings, which can lead to the occurrence of noise nuisance negatively affecting social relations.
Due to the fact that the analysis of the attractiveness of a location is the basis for properly determining the market value of real estate, the present article is dedicated to the methodology of assessing the noise nuisance of real estate surroundings. Four methods of assessment are proposed in the work: two of an objective nature, based on the measurements of noise and spatial analyses of data included in a strategic noise map, as well as two of a subjective nature, accounting for, among others, the individual perceptions of real estate users. The results of studies using the above methods can serve as a source of information on real estate as well as aid decision processes in the scope of real estate management. Theoretical deliberations were supported by a sample assessment of the noise nuisance of real estate surroundings carried out using two of the presented study methods.
Investment Risk in the Context of Price Changes on the Real Estate and Stock Markets
Authors: Wolski Rafał 
Published: April 2016

Abstract
The residential real estate market is thought to show a tendency for wide fluctuations in prices, as a result of which price bubbles appear. This element of risk has a direct bearing on investors interested in speculation and those seeking to meet their housing needs. Wide fluctuations in the values of real estate affect the investors’ financial situation in many ways, by determining the possibility of meeting one’s housing needs, reducing or sometimes raising creditworthiness, and by increasing investment risk measured by volatility. Omitting the obvious social dimension of the residential real estate market and concentrating on its financial aspects, the author of the article analyses to what degree wide swings in prices can be recognized as specific to this market. To this end, the volatility of prices in the stock market and in the secondary housing market in Poland is compared. An analysis is performed to establish which of them has higher average volatility measures or rates of return, i.e. which of them is more profitable or secure for investors. Statistical tests are used to find out whether average rates of return or measures of risk are equal or different between the two markets. The results of the research show that the secondary housing market and the stock market differ concerning cumulative average rates of return and standard deviations. In the first of them, they are respectively higher and lower.

Published: April 2016

Abstract
This paper presents a streamlined sub-system of decision-making in a real estate market with incomplete data. As we currently observe, various entities collect data and use databases, which entails a problem with their quality and completeness. This results from the specifics of the real estate market, particularly from the nature of the available information, access to it and integral uncertainty.
In the first part of this paper, we will present substantive guidelines for the development of a procedure for supplementing missing information. Afterwards, in order to verify the feasibility and effectiveness of the procedure, an implementation simulation will be conducted on the selected example. We would like to emphasize that all decisions are made under the conditions of an information gap.

Authors: Chaushi Agron , Chaushi Blerta Abazi , Ismaili Florije 
Published: April 2016

Abstract
Many governments in the world have created e-government initiatives including developed and developing countries. In order to better understand e-government evolution, different maturity models have been developed by many authors. In this paper the most cited e-government maturity models are analyzed using the meta-synthesis approach. As a result, five stages of e-government maturity are identified. The comparative results show the supported stages by each e-government initiative as important elements in the decision making process. This paper is attempting to show that although there are many models for measuring e-government maturity, they all converge on one common model. The contribution of this paper is in simplifying work for researchers when choosing the right maturity model.
Taiwan strait dispute
Authors: Kastrati Bilbil 
Published: April 2016

Abstract
The end of the Cold War resulted in a diffusion of the level of threat worldwide and concluded the system of bipolarity in the world. Beside the European continent, where the rivalries were at the highest level, the consequences of the end of the Cold War were especially visible in North-East Asia. A decrease of military activities of Russia and China, and the retreat of the USA from the region, give way for improvement of political and economical relations between the countries of the region. The end of hostilities produced by the Cold War no doubt have relaxed relations between countries in the region and opened ways for a new more peaceful co-existence. However, this does not mean that the region is not vulnerable to some of the hot spots such as North Korea, Spratly Parcels and especially Taiwan Strait. The latter is considered to be the most dangerous potential Asian zone of crisis in the twenty-first century.
The East Asian countries such as China, Japan and other Association of Southeast Asian Nations (ASEAN) countries are the world’s most growing economies and, at the same time, leaders in military acquisition; therefore, the potential for conflict and crises is current and real. This article examines one of these hot spots, namely the Taiwan Strait dispute, and assesses the possibility of this issue leading to a war between China, the USA and Japan. In order to have a clear view of the dispute the author will reveal some data in the introduction and then will explore relations, conflicts and interests between China, the USA and Japan vis-à-vis Taiwan and assess the risk that these countries might be drawn in potential war over the Taiwan Strait.
The right to dispose of an item of property acquired in marriage
Authors: Zendeli Emine 
Published: April 2016

Abstract
This research article analyzes the right of disposal of marital property in relation to the undertaking of those legal actions that imply the highest authorizations that legal subjects can have over things.
Having in consideration the fact that according to the legislation in the Republic of Macedonia, marital property is joint as are the authorizations of spouses over their joint items, it is important to determine the extent of the disposal, i.e. who disposes of the items of the joint property and to what extent. Referring to the normative framework, which regulates disposal relations of spouses, the article emphasizes the concept and importance of the authorization of disposal of things (alienation or assignment of things from joint ownership), through legal activities (sale, donation, exchange, etc.). In this context, the article tends to draw a divisive line between the administration with the joint item, referring to continuative actions and measures and the disposal of the thing, which is not continuative but, due to legal consequences it causes, has great importance in practice, and as a result, enjoys greater attention in legislators in terms of its limitation compared to the acts of administration with joint items in marriage.

Der Beitrag beschäftigt sich in einer praxeologischen Perspektive mit den Wirkungen, die compu­ter- und videogestützte Spielanalysen im professionellen Fußball entfalten können. Es werden Wis­senspraktiken skizziert, die sich mit dem Einsatz von Spielanalysesoftware herausgebildet haben und es werden daran anknüpfend konzeptionelle Überlegungen präsentiert, die in zwei Richtungen weitergeführt werden: Zum einen werden sie auf zentrale Grundannahmen der Praxeologie bezo­gen. Dabei zeigt sich, dass die Analyse der Wirkungen und Potentiale reflexiver Wissens- und Kön­nensformen in Praktiken ein Desiderat der praxissoziologischen Perspektive darstellt. Zum anderen werden aus den konzeptionellen Überlegungen zum softwaregestützten accounting Ideen zu den damit induzierten Veränderungen des Fußballspiels und des professionellen Fußballs entwickelt.
Motive und Hemmnisse für landwirtschaftliche Kooperationen

Published: April 2016

Zusammenfassung
Bisherige Studien zu den Entscheidungsfaktoren für oder gegen landwirtschaftliche Kooperationen haben vor allem ökonomische Aspekte fokussiert. Ziel dieses Beitrages ist es daher, neben ökonomischen Erwägungen auch die Relevanz „weicher“ Faktoren, wie einer ähnlichen Altersstruktur oder der Bekanntheit der Kooperationspartner, für eine Kooperationsentscheidung mittels eines Discrete Choice Experimentes zu untersuchen. Die Ergebnisse der Analyse zeigen, dass diese „weichen“ Faktoren eine hohe Entscheidungsrelevanz besitzen, ihr Einfluss auf den Erfolg einer Kooperation jedoch von den Landwirten möglicherweise unterschätzt wird.
Field Tests of Cement Fly-Ash Steel-Slag Pile Composite Foundation
Authors: Zhang Bin , Cui Shuai , Liu Zhen , Feng Fan 
Published: April 2016

Abstract
Steel slag is one of the main waste materials in the steelmaking process. As a result, a tremendous amount of steel slag is produced and deposited into storing yards every year. Recycling of the abandoned steel slag is of great environmental and economic value. This study investigates the usage of steel-slag concrete with fly ash as a kind of composite foundation pile material, which can be applied to multi-pile composition foundations for ground improvement involving different pile types. The micromorphology of the concrete, which uses steel slag as aggregate, is analyzed using scanning electron microscopy (SEM). The bearing characteristics of cement fly-ash steel-slag pile (CFS pile) composite foundations are investigated via field load tests, including settlement of the foundation base, horizontal displacement at different depths, distribution of vertical stress increase of the composite foundation, and stress increase of the soil around the pile hole. In addition, the effect of soil squeezing caused by the construction of a CFS pile is studied. To accomplish this, the variation in the increase in stress of the foundation at different distances in the horizontal direction is measured. The results suggest that the usage of steel slag as an aggregate can effectively satisfy the strength requirement of the pile. CFS pile composite foundations have the advantages of high bearing capacity, small settlement deformation, and limited horizontal deformation. This study demonstrates the potential usage of steel slag as aggregate in pile composite foundations, which can bring significant economic and environmental benefits.
The mitochondrial outer membrane protein MDI promotes local protein synthesis and mtDNA replication
Authors: Zhang Yi , Chen Yong , Gucek Marjan , Xu Hong 
Published: April 2016

AbstractEarly embryonic development features rapid nuclear DNA replication cycles, but lacks mtDNA replication. To meet the high‐energy demands of embryogenesis, mature oocytes are furnished with vast amounts of mitochondria and mtDNA. However, the cellular machinery driving massive mtDNA replication in ovaries remains unknown. Here, we describe a Drosophila AKAP protein, MDI that recruits a translation stimulator, La‐related protein (Larp), to the mitochondrial outer membrane in ovaries. The MDI‐Larp complex promotes the synthesis of a subset of nuclear‐encoded mitochondrial proteins by cytosolic ribosomes on the mitochondrial surface. MDI‐Larp's targets include mtDNA replication factors, mitochondrial ribosomal proteins, and electron‐transport chain subunits. Lack of MDI abolishes mtDNA replication in ovaries, which leads to mtDNA deficiency in mature eggs. Targeting Larp to the mitochondrial outer membrane independently of MDI restores local protein synthesis and rescues the phenotypes of mdi mutant flies. Our work suggests that a selective translational boost by the MDI‐Larp complex on the outer mitochondrial membrane might be essential for mtDNA replication and mitochondrial biogenesis during oogenesis.
