Classifying real money trading in virtual world

Virtual world activities related to the buying and selling of virtual currency, virtual items, and services with real world money are referred as Real Money Trading (RMT). Although there is a great deal of evidence for the growth of RMT in virtual world, there is also evidence to suggest that many companies are struggling to become involved with RMT. A framework for classifying RMT in virtual world is essential for devising successful virtual business strategies. A key component in the process of formulating the optimal competitive strategy is to understand the unique characteristics of RMT and the implications behind those characteristics. This study aims to propose a classification of RMT based upon the characteristics of products and services, the transaction and marketplace, as well as the currency and exchange systems.
Comparison of Sol Gel and Dehydration Magnesium Oxide (MgO) as a Catalyst in Michael Addition Reaction

Magnesium oxide (MgO) was prepared by dehydration of magnesium carbonate method and sol gel method. The prepared MgO powders were calcined at the temperature of 200, 400, 600, and 800 oC for two hours. Then, the samples were characterized by using fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscope (SEM). In order to investigate the prepared MgO, the samples were applied in Michael addition reaction to produce diethyl 2-(3-oxo-1,3-dipehnylpropyl) malonate. The highest percentage yield of 94% was obtained from MgO pepared from sol gel method and calcined at 800 oC.
IMPROVEMENT PRODUCTION EFFICIENCY AND CARCASS QUALITY THROUGH FEED RESTRICTION PROGRAMS IN BROILER CHICKENS

The main objective of broiler rearing industry is production of high quality broiler carcasses that will be acceptable for consumers; Acceptability depends on the quality and quantity of edible parts of carcasses, and the amount of muscle mass in carcass. Feeding strategy in growing broiler chickens should be to produce animals with maximum lean body mass, highest feed conversion ratio and maximum body weight. Continuous genetic selection and improvement in nutrition have led to a very fast growth rate in modern strains. That early-life fast growth rate is accompanied by a number of problems, such as body fat deposition, high incidence of metabolic disorders, high mortality, and high incidence of skeletal diseases. The feed restriction programs is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken in alleviate the incidence of some metabolic diseases and can be used to produce a leaner bird and reduce the unfavorable effects of fat on human health, and to reduce fat deposition in broiler carcasses could be profitable in broiler chickens production. This article implicated on new findings in about different feed restriction programs effects on production efficiency and carcass quality in broiler chickens.
EFFECT OF CAMEL MILK ON MICROBIOLOGICAL AND CHEMICAL QUALITY OF SOFT CHEESE

Soft cheese made from buffaloes milk mixed with camel milk at different concentrations (90, 80, 70, 60 %) and (10, 20, 30, 40 %) respectively, the soft cheese (control and their treatments) were stored for 60 days at 4 0 C. The chemical composition, microbiological and organoleptic properties were determined for all soft cheese samples during storage periods (fresh, 30, 45 and 60 days). The chemical compositions results showed that the values of total solids, fat, total protein and ash were increased with increasing the amount of camel milk, while salt was decreased during storage periods. The microbiological results revealed that camel raw milk was contained 13X 10 6 , 12X 10 4 , 13X10 2 , 1X10 4 and 3X10 3 cfu/ ml for total bacterial count (T.B.C), total coliform (T.C.), faecal coliform (F.C.), total fungi (T.F.) and lactic acid bacteria (L.A.B) respectively. Yeasts E. coli, Listeria monocytogenes Staph. aureus and Salmonella were not detected in raw camel milk. Buffaloes' milk were contained 8X10 5 , 3X10 4 , 6X10 2 , 4X10 4 and 1X10 2 cfu/ml for T.B. C, T.C, F.C, T.F and L.A. B respectively, E. coli, Staph aureus, L. monocytogenes and Campylobacter were detected while yeasts and Salmonella not detected. The different concentrations (20, 30, 40 %) of camel milk induced completely elimination of E. coli, Staph. aureus, L. monocytogenes and fungi after 30 days of refrigerator (4 0 C ) storage while concentration of 10 % camel milk induced completely elimination of Staph. aureus and fungi after 60 days of refrigerator storage. On the other hand 100 % buffaloes milk cheese as a control was contaminated with E. coli, Staph aureus and L. monocytogenes during storage periods, total fungi was increased during storage periods with presence of different types of fungi especially after 60 days of refrigerator

These problems include typical analytical problems as well as the most uncommon challenges that are futuristic for the big data only. The article breaks down problems for each step of the big data analysis process and discusses these problems separately at each stage. It also offers some simplistic ways to solve these problems.
Cobreaking of Stock Prices and Contagion Running Title : Cobreaking of Stock Prices and Contagion

Financial crises have shown that dramatic movements in one financial market can have a powerful impact on other markets. The paper proposes to use cobreaking to model comovements between financial markets during crises and to test for contagion. It finds evidence of cobreaking between stock returns in developed markets. Finding cobreaking has implications for the diversification of international investments. For emerging market stock returns the evidence of cobreaking is mainly due to the non-financial event of the 9/11 terrorist attacks in 2001. Financial crises originating in one emerging market do not spread to other markets, i.e., no contagion. JEL Classification: G15, C32
Critical Success Factors of CRM System Implementation

This study identifies 16 critical success factors (CSFs) of CRM implementation and develops relevant hypotheses through literature reviewing. The results reveal that the major CSF for the CRM implementation is the “top management support and involvement”. There are some differences found between consultant responses and practitioners’ in 4 critical success factors, “the ability of project manager”, “education and training”, “management of project scope”, “attitude of personnel”. Moreover, the finding indicates that some more important CSFs do not belong to CRM system quality aspect, but CRM project scope aspect and organizational characteristics aspect. The implications of results are discussed.
Corporate Social Responsibility Issues in the Slovak E-commerce Companies

Present time is marked by the expansion of online shopping. However, E-commerce companies, which are providers of online shops, are expected not only to meet the needs of online customers but also to take responsibility for their actions. In Slovakia, there are numbers of E-commerce companies but only a small part of them follows the principles of Corporate Social Responsibility (CSR). The aim of the paper is to identify CSR issues in the Slovak E-commerce companies. The main conclusion of the paper are: The CSR concept should be natural to every E-commerce company and should focus on CSR activities listed in the paper. The paper is based on primary and secondary information gathered through extensive literature review using internet, research databases and the author's own experience. The paper is organised as follows: section 1 aims at approaches to define the CSR notion; section 2 describes the methodology approach; section 3 comparatively review the primary data on CSR issues from the point of view of customers and the secondary data on CSR strategies of selected Slovak socially responsible E-commerce companies; section 4 discusses the results of primary and secondary research.
SUPERCRITICAL CO2 IN A GRANITE-HOSTED GEOTHERMAL SYSTEM: EXPERIMENTAL INSIGHTS INTO MULTIPHASE FLUID-ROCK INTERACTIONS

Geochemical modeling and hydrothermal experiments were conducted at 250C and 25-45 MPa to evaluate associated geochemical and mineralogical relationships and to determine how geothermal systems may respond given „spontaneous‟ injection of CO2 into a granitic reservoir. Water + granite experiments reacted for ~28 days, and then two of the three systems were injected with supercritical CO2 (scCO2) and reacted for at least an additional 42 days. In addition to other minerals, the baseline water + granite experiment resulted in illite formation. The water + granite + scCO2 experiments resulted in smectite formation. No carbonate minerals were observed as reaction products of these experiments. A baseline understanding of reactions involving a multicomponent groundwater, a granite, and scCO2 has been established. Results may improve our understanding of processes in natural and enhanced geothermal systems (EGS).
A Real-time QRS Detector Based on Low-pass Differentiator and Hilbert Transform

Electrocardiogram(ECG) is an important physiological signal of the human body. It is widely used in identification and arrhythmia detection. The first step of ECG application is signal segmentation, that is, the QRS detection. An effective and real-time QRS detection algorithm is proposed in this paper. A differentiator with adjustable center frequency is used to capture the first derivative information of the frequency band of the electrocardiogram. Then Hilbert transform is used to generate the envelope of the first derivative. After that, a dual threshold method is introduced to decrease FP and FN. Finally, a more precise R wave position is determined based on derivative method. The detector is validated on MIT-BIH arrhythmia database. The result show that the proposed algorithm has a high Sensitivity of 99.87%, Specificity of 99.84%, and the detection error rate is 0.28%. The average execution time of a 30 minutes record is 2.45s.
Preparation of Polyaniline/ZnO Films by Electrochemical Polymerization

A series of polyaniline (PANI)/zinc oxide (ZnO) nano-particle (diameter 70 nm) composite films were prepared by electrochemical polymerization in the presence of ZnO nanoparticle. Furthermore, PANI-ZnO/PVA (PVA = polyvinyl alcohol) double-layer system was prepared. We first report preparations of a photocatalyst/conducting polymer light absorber by using ZnO nano-particles.
The Functions of CHIP in Age Related Disease

CHIP is a key component of the protein homeostasis or ‘Proteostasis’ network that maintains protein structure and function as a way to ensure the integrity of the proteome in individual cells and the health of the whole organism. Proteostasis influences the biogenesis, folding, trafficking and degradation of proteins. Originally identified as a Hsc70 associated protein and a co-chaperone CHIP has E3-ubiquitin ligase activity and also displays an intrinsic chaperoning ability. It has become clear that CHIP is a multi-functional protein with roles in cellular processes that go beyond its co-chaperone activity. Not surprisingly, by unravelling the functions of CHIP, we are beginning to appreciate that loss of CHIP’s integrity can lead to the development of several serious pathological conditions. Here we will describe the key features of CHIPs structure and functions with an emphasis on the non-canonical activities of CHIP before concentrating on the role it plays in protecting against the age associated pathologies of neuro degeneration and cancer.
Clustered features for use in stereo vision SLAM

SLAM, or simultaneous localization and mapping, is a key component in the development of truly independent robots. Vision-based SLAM utilising stereo vision is a promising approach to SLAM but it is computationally expensive and difficult to implement. New feature manipulation techniques are proposed which incorporate relational and positional information of the features into the extraction and data association steps.
Clustering and Emergent Features of the Regional Economics of the Kemerovo Region

The subject matter of this research is the processes of clustering in the regional economics. Currently, clustering is the most efficient form of conducting the innovative activity. For industrial regions, such as the Kemerovo region, the benefits of clustering comprise the creation of an efficient production scale rise. The purpose of this article is to study the ways to create the integrated tools formations in the industrial region. In addition, clustering advantages are imposing a qualitatively new impetus onto the development of the economics as a result of a mutually beneficial relationship emerged between industry and research organizations, universities, innovative businesses and the public sector. The paper concludes that development in the region of several cluster formations can provide the effect of the emergence of functioning of the entire regional economics. The effect in question is caused by the fact that the sum of potentials of the individual elements of the regional economics is less than the total capacity of a cluster in which these elements interact with each other. This feature provides for a number of advantages of regional economies considered in this article. In addition, the authors have identified problems that have a negative impact on the development of the innovation sphere of an industrial region.
Formal reporting for information exploitation and dissemination in Joint ISR

In complex operational scenarios where multiple nations and forces cooperate, flexible System of Systems (SoS) architectures being customizable to specific operations are needed. Relevant operational processes as defined within Joint ISR (Intelligence, Surveillance and Reconnaissance) and the Intelligence Cycle need to be supported. To maximize efficiency and effectiveness of Joint ISR capabilities, each Joint ISR result needs to answer the corresponding information requirement accurately. Commanders must receive the relevant information in a condensed, well-prepared manner instead of being overflowed with large amounts of (raw) data. Ensuring a common understanding of each exchanged piece of information within the defence coalition is also of utmost importance. Architectures supporting these requirements need to make use of relevant standards and agreements for data/ information management. As reports may be provided by all Joint ISR capabilities, the topic of reporting is of high importance, here. Within the described context, our publication deals with formal reporting which can be defined as organizational process at which relevant information is provided as formal reports, i.e., as documents being structured according to pre-defined (agreed) rules. We present means for ensuring allied interoperability and further (semi-)automatic processability of the information being contained in formal reports by technical means and under consideration of the relevant doctrines and standards. We also address specific means needed to ensure the creation of formal reports of high quality. Finally, we discuss current issues and new requirements on formal reporting which have to be still addressed in the field of Joint ISR.
Risk Effects versus Monetary Effects in the Determination of Short-term Interest Rates

Economic theory offers two distinct approaches to the modeling of interest rates. At the microeconomic level, interest rates are modeled as an outcome of intertemporal optimization by investors, so that real interest rates are determined entirely by the real variables that characterize risk. At the macroeconomic level, short-term behavior of interest rates is usually thought of as being governed by the money-demand function. This paper tests a model that encompasses both views, using data for four countries. The results suggest that risk factors are empirically insignificant in explaining interest-rate behavior.

An Approach to Technological Processes Automation using Technological Coalitions Based on Discrete Event Models

There is a common feature in all control systems in big plants that use complicated technologies. It is that their control systems usually consist of two parts. There is the automatic control part for simple control tasks and the supervisory control part for other tasks. Functional division between these parts is not stable and depends on how mature is the automatic control part. Of course the share of automatic control generally tends to increase, even though in the more complex cases this growth is checked by the lack of suitable algorithms. Thus supervisory (i. e. human) control will always remain necessary until algorithmization of all aspects of technological processes is completed. Today there are several methodological problems which remain outside the scope of existing approaches to control system design, which causes inherent flaws in the resulting algorithms. We propose to introduce a new approach that will address these issues, and we will explain our approach using a common type of industrial technologies called flow technologies. A few words about these. A lot of different tanks, valves, pumps, separators, desalters (demineralizers), heaters, fractionators, coolers, petroleum gas flare system, boosters and some other devices (aggregates) are connected usually by pipes or conveyor belts and some flows of different substances pass through them while the properties of these substances undergo numerous changes. This is what in the present paper we are going to call “flow structure of technology” or just “flow technology”. We must stress that we will consider here only big plants which have a lot of types of technological equipment. We should notice that flow technologies are used extensively in oil and gas industry, chemistry (cryochemistry), power engineering, hydrometallurgy and in other types of heavy industries, manufactures and processing plants. We have here roughly outlined the areas where our research is likely to prove useful; those interested in the technological aspects of particular industries should refer to the literature on the subject. Flow technology is quite a common kind of technology – for example, we really can refer to processes of production and preparation in oil fields all over the world. Multi-field plants show appropriate example of this technology. It is a big illusion to think that the black liquid (the pure oil) is produced direct from wells. Usually only an oil-gas-water-sand mixture is really produced from the wells. Figure 1 below shows the structure of a typical oil-plant. There are several input flows from different oil-fields and
Light-sensitive plasticity genes in Arabidopsis thaliana: Mutant analysis and ecological genetics

To explore how altered plasticity genes affect whole-plant phenotypes and plant fecundity, we conducted an experiment with isogenic lines of Arabidopsis thaliana, representing a wild type and seven photomorphogenic mutants. We exposed all genotypes to a 3 × 3 factorial array of light intensity and water availability. We documented altered plasticity to light intensity not only for mutants insensitive to blue wavelengths, but also for mutants insensitive to red and far-red wavelengths. Our results are consistent with models of co-action between these two distinct photoreceptory systems. Photomorphogenic mutants showed altered plasticity to light intensity not only for seedling and rosette morphology, but also for the duration of the vegetative and reproductive phases. Fruit production and two other performance traits showed no significant variation for plasticity to light intensity, but the means of all three performance traits differed significantly among genotypes. Notably, mean fruit production was much lower in the wild type than in the blue-insensitive and far-red insensitive mutants. The high fruit production of these mutants declined with decreasing water availability. In contrast, the low fruit production of the wild type was quite stable with declining water. However, we found only marginally significant variation among genotypes for the water-mediated plasticity of fruit production. Our comparisons of photomorphogenic mutants and wild-type plants suggest that there may be significant costs associated with the photoreceptory systems. However, the enhanced fitness of mutant genotypes may not be realizable in natural conditions, where very low water availability or curtailed growing seasons may be common.
Generation of fibrillatory dynamics in cardiac tissue: fractional diffusion as arrhythmogenic mechanism modelling tool

Atrial fibrillation is characterized by complex propagation patterns. The rotor hypothesis indicates that some episodes are sustained by organized activity in form of spiral waves. Additionally, structural complexity plays an active role in the modulation on electrophysiological characteristics. Computer modelling of atrial propagation has been used to study the dynamics behind atrial fibrillation. To include electrical and structural remodelling under a single model can contribute to understand the initiation and perpetuation mechanisms of the arrhythmia. 638 Juan P. Ugarte et al. In this work we propose a model of atrial fibrillation based on fractional diffusion equation, which is a generalization of the standard diffusion that considers the order of the spatial derivative as a real number. We show that, the fractional order has influence over the atrial action potential and tissue features. Moreover, different patterns of fibrillatory dynamics could be simulated starting from the generation of a rotor. Therefore we postulate the fractional diffusion as an arrhythmogenic mechanism modelling tool.
Putative neuroprotective role of visfatin against cognitive dysfunction in obese patients Physical Education

Objectives: Visfatin (adipokine) is thought to have neuroprotective properties. The aims of to determine the type and extent of prefrontal cortical dysfunction and to evaluate the potential neuroprotective role of visfatin. Methods: Sixty-one obese patients were included. A diagnosis of primary obesity was made on the basis of a BMI > 30. Visfatin serum levels were determined by enzyme immunoassay. The Wisconsin Card Sorting Test (WCST) was used to assess prefrontal cortex-mediated cognitive function. Results: Visfatin levels were not correlated with age or BMI. However, patients with higher visfatin levels tended to show an overall improvement in WCST scores. Nonetheless, a significant positive correlation (P = 0.032) was found only between high serum visfatin levels and the number of correctly completed categories in the WCST. Discussion: The results described herein indicate a possible neuroprotective effect of visfatin against obesity-related cognition dysfunction, particularly in regard to the categorizing capacity associated with executive function.
An Everett Perspective on Bohr and EPR

After summarising a previously given analysis of Bohr's reply to Einstein, Podolsky and Rosen (EPR), this chapter endorses the claim made by Everett himself that Everettian quantum mechanics `in a certain sense bridges the positions of Einstein and Bohr'. On the one hand, it shows how Everett's theory provides a reconstruction of Bohr's viewpoint of complementarity as applied to the EPR case and a justi�cation of his criticism of EPR's `criterion of reality'. On the other hand, it includes a notion of physical reality that is independent of any observational context, and suggests a remaining shortcoming of Bohr's reply.
