The influence of selected parameters on the efficiency and economic charactersistics of the oxy-type coal unit with a membrane-cryogenic oxygen separator
Authors: Kotowicz Janusz , Berdowska Sylwia 
Published: August 2016

AbstractIn this paper a 600 MW oxy-type coal unit with a pulverized bed boiler and a membrane-cryogenic oxygen separator and carbon capture installation was analyzed. A membrane-cryogenic oxygen separation installation consists of a membrane module and two cryogenic distillation columns. In this system oxygen is produced with the purity equal to 95%. Installation of carbon capture was based on the physical separation method and allows to reduce the CO2emission by 90%. In this work the influence of the main parameter of the membrane process – the selectivity coefficient, on the efficiency of the coal unit was presented. The economic analysis with the use of the break-even point method was carried out. The economic calculations were realized in view of the break-even price of electricity depending on a coal unit availability.
Numerical simulation of thermal-hydraulic processes in the riser chamber of installation for clinker production

Published: August 2016

AbstractClinker burning process has a decisive influence on energy consumption and the cost of cement production. A new problem is to use the process of decarbonization of alternative fuels from waste. These issues are particularly important in the introduction of a two-stage combustion of fuel in a rotary kiln without the typical reactor-decarbonizator. This work presents results of numerical studies on thermal-hydraulic phenomena in the riser chamber, which will be designed to burn fuel in the system where combustion air is supplied separately from the clinker cooler. The mathematical model is based on a combination of two methods of motion description: Euler description for the gas phase and Lagrange description for particles. Heat transfer between particles of raw material and gas was added to the numerical calculations. The main aim of the research was finding the correct fractional distribution of particles. For assumed particle distribution on the first stage of work, authors noted that all particles were carried away by the upper outlet to the preheater tower, what is not corresponding to the results of experimental studies. The obtained results of calculations can be the basis for further optimization of the design and operating conditions in the riser chamber with the implementation of the system.

The Sincerity of Questioned People
Authors: Haller István 
Published: August 2016

Abstract
Applying questionnaires is one of the basic methodologies in sociology. Usually sociologists consider that choosing a representative sample and properly formulated questions, the results will show real characteristics of the society. But the following main question should always be analyzed: are people sincere? Psychology proved that we try to meet the society's expectation. In this way the answers do not represent the questioned person’s thought, but what they considered expect from society. The present study analyzes the sincerity of police officers, asked to complete a questionnaire for a scientific purpose, respecting the principle of anonymity. The results show that around 2/3 of the questioned persons did not give sincere answers, offering importance for an inexistent person (Schnade). By analyzing the answers to another question (the importance of the television and the bicycle for the questioned persons), it was found that insincere people could be not easily excluded: the sincerity is changing from question to question; some persons are sincere regarding a specific domain and not sincere in another domain.
Ubuntu and Capabilities Approach: Basic Doctrines for Calibrating Humanitarian Action
Authors: Rapatsa Mashele 
Published: August 2016

Abstract
This article explores prospects of using Ubuntu and Capabilities Approach to expand the scope of humanitarian action, to design one which serves humanity better even in the absence of disaster to essentially fulfil human development needs. It is considerate of the fact that humanitarian works contributes immensely in determining the extent to which humanity thrives. The traditional view on humanitarianism presupposes action-driven initiatives geared towards devising interventions to restore or reinforce human social order, improve livelihoods and quality of life. In sociological terms, human development is dependent on realizing and safeguarding, amongst others, human well-being, civil liberties and social security. The article utilizes core values enshrined in Ubuntu, Africa’s historic philosophy of life, and Amartya Sen’s Capabilities Approach as tools of analysis, with the view to expressing how to operationalize what should be considered stable humanitarian conditions and human well-being. Owing to persistent socio-economic challenges, especially the poverty problem, it is asserted that humanitarian action ought to depart from being a post-disaster intervention strategy, to being a pro-active and preventative pre-disaster orientated action, intended to nurture well-being and resultantly enable human development.
Parasites of edible land snails in Edo State, Nigeria
Authors: Igbinosa I. B. , Isaac C. , Adamu H. O. , Adeleke G. 
Published: August 2016

Summary
Land snails are sources of protein to man and are hosts to a number of parasites. It is imperative that the roles of the snail hosts and parasites are clearly defined. Before then however, the parasites of the different land snails collected in any locality should be identified. Land snails were collected in the wild in both dry and wet seasons. The internal organs and the faeces were examined for the presence of parasite. In the rainy season of 2015, a total of 272 snails were collected across four major towns (Benin, Uromi, Ekpoma and Auchi) in Edo State, Nigeria, while in the dry season, fewer snails (n=91) were handpicked. The snail species seen are: Achatina achatina (Linnaeus, 1758), Achatina fulica (Férussac, 1821), Acharchatina marginata (Swainson, 1982), Limicolaria aurora (Jay, 1839), L. flammea (Müller, 1774) and Limicolariopsis spp. The larvae of Strongyloides stercoralis were isolated from the various snail species with overall prevalence of 54.04 %. Snails positive with Alaria mesocercariae were L. aurora, L. flammea and Limicolariopsis spp. Additionally, few L. flammea were positive of the cercariae of Drocoelium dedriticum. Meanwhile, some samples of A. fulica harboured larvae of Angiostrongylus cantonesis, sporocysts of Fasciola gigantica and Schistosoma mansoni. Therefore, these edible snails could pose serious health hazard to man and animals by serving as a possible alternative parasite transmission route.

Authors: Almatary A. M. , Bakir H. Y. 
Published: August 2016

SummaryVisceral Larva Migrans (VLM) syndrome is commonly caused by larvae of roundwormsToxocara canisorToxocara cati. Human toxocarosis is a soil-transmitted zoonosis, which may result in partial or general pathological changes in host tissues. We reported a case of 14-year-old boy presented with severe dry cough without dyspnea, mild chest and abdominal pain with general fatigue. Examination of peripheral blood showed marked increase in eosinophils. The chest radiography showed an infiltrative shadow in the lung fields. Chest CT demonstrated multiple opacities in both lungs. Abdominal CT showed multiple low attenuation areas in the liver. Ultrasound guided liver biopsy revealed granulomas with severe eosinophilic infiltration. The boy was treated with albendazole and responded radically. It is worth mentioning that this is the first case of hepato-pulmonary VLM syndrome in Egypt.
Depressive symptoms, hostility, and hopelessness in inner-city adolescent health clinic patients: factor structure and demographic correlates
Authors: Pajer Kathleen A. , Edwards Michael C. , Lourie Andrea E. , Fields Sherecce , Kalman Savannah 
Published: August 2016

Abstract

Background:
Depression, hostility, and hopelessness are risk factors for adult cardiovascular disease (CVD). People living in inner-city environments are particularly vulnerable. These associations may begin in adolescence, but research in this area is hampered by inadequate knowledge about how these negative psychological factors are related in teens and how they are affected by demographic characteristics. We hypothesized that depression, hostility, and hopelessness are one construct, and that this construct would be associated with race and gender in attendees at an inner-city adolescent health clinic.

Methods:
Two hundred and forty-six 15–18-year-old patients filled out instruments measuring depressive symptoms, hostility, and hopelessness. Confirmatory factor analysis was used to determine whether the negative psychological factors comprised a single construct or three separate ones. General linear modeling (GLM) was used to test the associations between demographic characteristics and the results of the factor analysis.

Results:
Depressive symptoms, hostility, and hopelessness were best characterized as three separate constructs, not one (root mean square error of approximation (RMSEA)=0.041, 90% confidence interval (CI)=(0.035, 0.047), comparative fit index (CFI)=0.98). There were no significant relationships between demographic variables and depressive symptoms or hostility. Six percent of the variance in hopelessness scores was accounted for by gender, race, and the interaction between the two (F=3.76; p=0.006), with White males, reporting the highest levels of hopelessness.

Conclusion:
In an urban adolescent health clinic population, depressive symptoms, hostility, and hopelessness were best understood as three separate constructs. Hopelessness was significantly higher in White males. Implications for future clinical research on negative psychological factors in teens are discussed.
How ideas of transformative learning can inform academic blogging
Authors: Hammond Michael 
Published: August 2016

Abstract
This paper looks at blogging by academics and argues that there is a niche role for an academic blog informed by principles of transformative learning. I begin by describing my experiences of blogging, first, as a reader while carrying out my own doctoral research, next, as a teacher introducing blogs to my students, then as a writer of my own journal blog. I suggest that transformative learning principles provide a frame of reference for understanding these experiences, in particular, by offering an idea of autonomy which puts subjective experience in social contexts. I then suggest that academics interested in transformative learning might learn a more engaging style of writing from bloggers.
A Child of the City: a Longitudinal Study of Stratification and Migration in a Rajasthan Village
Authors: Jones J Howard M 
Published: August 2016

Abstract
By reference to a multi-caste and tribal village in southern Rajasthan the paper examines the degree to which caste and tribal membership impacts on different aspects of migration, e.g. commencement, form, destination, duration, and types of work undertaken. Using a livelihoods approach, supplemented by other perspectives and concentrating on four migration streams (three domestic, one international), data collected over a period of nearly thirty-five years indicates that patterns of migration are far from random. It is argued that the use of official stratification categories in migration surveys can obscure important differences within caste groupings. Short-term circular migration, underestimated in national surveys, is shown to be substantial, especially for the tribal migrants in the village. While position in the social structure differentially affects aspects of migration across the village hierarchy, examples are given of individual migrant agency overcoming structural constraints.
Remembrance and Architecture the House of Fates Project
Authors: Benárd Aurél 
Published: August 2016

Abstract
The changes which took place a quarter of a century ago in the countries of Europe’s Eastern Bloc transformed the social conventions of the time. A kind of social dialog has been started, about the Holocaust amongst other things. New memorials and monuments dedicated to the Holocaust have been constructed in the countries of the region as a result. Several phases can be identified in the building of monuments to the Holocaust over the past 25 years. These changes in the process of recollection and in the building of the monuments themselves are typified by the House of Fates project. The memorial center was built in Budapest for the 70th anniversary of the Holocaust. But the changes in recollection did not stop there, did not come to a standstill in Hungary. It is a mark of the sensitivity of the subject that although the center was finished by the fall of 2015, it has still not opened its gates to the public. In the meantime the project has appeared in several Hungarian professional journals, however these articles do not venture far beyond the realm of basic description. Here we are attempting to analyze the project architecturally. Our analysis shows how the initial usage of primary symbols turns to more contemplative, more abstract images and devices.
Why Hayek is Right against Keynes?
Authors: Salin Pascal 
Published: August 2016

Abstract
It is argued in that paper that Hayek came out the winner in the debate opposing him to Keynes. Keynes argued in favour of specific economic policies without a prior analysis of the causes of business cycles. His discussion of economic policy is backed on an ad hoc account of cycles that would, according to him, be based on the irrationality of economic actors and the non-effectiveness of price adjustments. As a result, he says, quantities have to adjust which leads to unemployment. Hayek and the Austrians propose, by contrast, a well-articulated theory of business cycles rooted in a micro-economic approach (agents are rational, albeit badly informed). This leads them to identify the source of the cycle in monetary shocks. In our modern economies, as in the Austrian theory, economic policies conducted by the states are the main driver of the cycles. The consequences of this analysis in terms of economic policy are clear: When excessive regulation and fiscal burden cause a recession the solution must be found in tax cuts and deregulation, not in (Keynesian) monetary or fiscal policies that will do nothing but foster mal-investment.

Abstract
Increased levels of homocysteine (HCYS) represent a risk factor for a series of physiopathological conditions: mental retardation, cardiovascular and neurodegenerative diseases, Parkinson's and Alzheimer's disease, depression, osteoporosis, endothelial dysfunction and inhibition of cell proliferation. This paper aims to present the pathophysiological implications of HCYS and the correlation of hyperhomocysteinemia (H-HCYS) with critical condition in the intensive care unit (ICU). Hypovitaminosis B and folate deficiency is directly involved in the inhibition of HCYS metabolism and the accumulation of HCYS in the plasma and tissues. Critically ill patients are more prone to H-HCYS due to hypermetabolism and accelerated synthesis produced by reactive oxygen species (ROS). In conclusion it can be affirmed that the determination and monitoring of HCYS plasma levels may be of interest in optimizing the therapy for critically ill patients. Moreover, by controlling HCYS levels, and implicitly the essential cofactors that intervene in the specific biochemical pathways, such as vitamin B6, vitamin B12 and folic acid can provide a diversified and personalized treatment for each patient.
Binary to Octal and Octal to Binary Code Converter Using Mach–Zehnder Interferometer for High Speed Communication

Published: August 2016

Abstract
Binary to octal and octal to binary code converter is a device that allows placing digital information from many inputs to many outputs. Any application of combinational logic circuit can be implemented by using external gates. In this paper, binary to octal and octal to binary code converter is proposed using electro-optic effect inside lithium-niobate based Mach–Zehnder interferometers (MZIs). The MZI structures have powerful capability to switching an optical input signal to a desired output port. The paper constitutes a mathematical description of the proposed device and thereafter simulation using MATLAB. The study is verified using beam propagation method (BPM).

Published: August 2016

AbstractBackground:The aim was to evaluate the influence of the new International Association of Diabetes and Pregnancy Study Groups (IADPSG) guidelines for screening of gestational diabetes mellitus (GDM) on GDM prevalence in a cohort from a Swiss tertiary hospital.Methods:This was a retrospective cohort study involving all pregnant women who were screened for GDM between 24 and 28 weeks of gestation. From 2008 until 2010 (period 1), a two-step approach with 1-h 50 g glucose challenge test (GCT) was used, followed by fasting, 1- and 2-h glucose measurements after a 75 g oral glucose tolerance test (OGTT) in case of a positive GCT. From 2010 until 2013 (period 2), all pregnant women were tested with a one-step 75 g OGTT according to new IADPSG guidelines. In both periods, women with risk factors could be screened directly with a 75 g OGTT in early pregnancy.Results:Overall, 647 women were eligible for the study in period 1 and 720 in period 2. The introduction of the IADPSG criteria resulted in an absolute increase of GDM prevalence of 8.5% (3.3% in period 1 to 11.8% in period 2).Conclusions:The adoption of the IADPSG criteria resulted in a considerable increase in GDM diagnosis in our Swiss cohort. Further studies are needed to investigate if the screening is cost effective and if treatment of our additionally diagnosed GDM mothers might improve short-term as well as long-term outcome.
Effects of Discrete Damping on the Dynamic Behaviour of Rotating Shaft through Extended Lagrangian Formulation
Authors: Rastogi Vikas 
Published: August 2016

Abstract
The main focus of the paper is touted as effects of discrete damping on the dynamic analysis of rotating shaft. The whole analysis is being carried out through extended Lagrangian formulation for a discrete – continuous system. The variation formulation for this system is possible, considering the continuous system as one-dimensional. The generalized formulation for one dimensional continuous rotary shaft with discrete external damper has been obtained through principle of variation. Using this extended formulation, the invariance of umbra-Lagrangian density through extended Noether’s theorem is achieved. Rayleigh beam model is used to model the shaft. Amplitude equation of rotor is obtained theoretically and validated through simulation results. The simulation results reveal the important phenomena of limiting dynamics of the rotor shaft, which is due to an imbalance of material damping and stiffness of the rotor shaft. The regenerative energy in the rotor shaft, induced due to elasticity/stiffness of the rotor shaft, is dissipated partially through the in-span discrete damper and also through the dissipative coupling between drive and the rotor shaft. In such cases, the shaft speed will not increase with increase in excitation frequency of the rotor but the slip between the drive and the shaft increases due to loading of drive.
Study of Heat Transfer with Nonlinear Thermal Radiation on Sinusoidal Motion of Magnetic Solid Particles in a Dusty Fluid
Authors: Bhatti M. M. , Zeeshan A. , Ellahi R. 
Published: August 2016

Abstract
In this article, heat transfer with nonlinear thermal radiation on sinusoidal motion of magnetic solid particles in a dust Jeffrey fluid has been studied. The effects of Magnetohydrodynamic (MHD) and hall current are also taken under consideration. The governing equation of motion and energy equation are modelled with help of Ohms law for fluid and dust phases. The solutions of the resulting ordinary coupled partial differential equations are solved analytically. The impact of all the physical parameters of interest such as Hartmann number, slip parameter, Hall parameter, radiation parameter, Prandtl number, Eckert number and particle volume fraction are demonstrated mathematically and graphically. Trapping mechanism is also discussed in detail by drawing contour lines. The present analysis affirms many interesting behaviours, which permit further study on solid particles motion with heat and mass transfer.
