Abstract

BACKGROUND
The objective of this study was to investigate the predictive power of a high-sensitivity cardiac troponin I (hs-cTnI) assay for cardiovascular events and mortality in a large population of older community dwellers.

METHODS
Blood was collected from 5764 individuals (age 66–98 years) during the period of 2002–2006 and the outcome as to all-cause death and incidence of cardiovascular disease (CVD) and coronary heart disease (CHD) followed up to 10 years. hs-cTnI (Abbott) was measured in serum to assess the association of this marker with CVD, CHD and death, and finally, to compare the results with conventional risk factors by multivariable statistical analysis.

RESULTS
The median (interquartile range) concentrations of hs-cTnI were 8.4 ng/L (5.6–14.2 ng/L) and 5.3 ng/L (3.8–8.1 ng/L) in men (2416) and women (3275), respectively, and the concentrations increased linearly with age. Outcomes as to all-cause death and incidence of CVD and CHD were significantly associated with increasing concentrations of hs-cTnI beginning well below the 99th percentile concentrations. The associations with outcome remained after adjustments for conventional risk factors and were similar in men and women.

CONCLUSIONS
Our findings suggest that hs-cTnI reflects the status of the myocardium even in seemingly healthy individuals and that the measurements of hs-cTnI may be useful for primary prediction of heart disease; this should form the basis for future prospective clinical trials for determining whether measuring hs-cTnI can be used in the prevention of CVD/CHD.
Film production as a ‘mirror of society’: The history of a video film art group in Dar es Salaam, Tanzania
Authors: Böhme Claudia 
Published: March 2016

Abstract
The Tanzanian video film industry is one example for the changes in popular arts production due to the introduction of the medium video film. The shift to the medium video film has created new visual styles and restructured physical and social spaces of production. Focusing on the history of the video film art group White Elephant, this article aims to show how the production of video films under conditions of intense competition and time pressure is a site of struggle over aesthetics, resources, identities and status. Relating the film groups to the history of art groups in Eastern Africa will point to the differences and continuities between the independent commercial production of video film and former popular art production as well as their relation to the state. This fields of production and the struggles within can be seen as a ‘mirror of society’ characterizing the dynamics of social change in contemporary Tanzania.

Authors: Overbergh Ann 
Published: March 2016

Abstract
This article analyses the economic structure, market dynamics and power relations in Kenya’s Riverwood movie circuit. Similarities and differences with better-known African popular cinema industries are highlighted and tentatively explained. The article pays attention to historical background, context factors, individual agency and questions of justice and fairness in the circuit. Riverwood may at first glance appear to be just another example of the African popular cinema genre, but on closer inspection shows as many dissimilarities as similarities with, for instance, Nollywood and Bongowood.

Published: March 2016

<p>Many mathematical models for the spread of infectious diseases in a population assume homogeneous mixing, but due to spatial distribution, there exist distinct patches with unique disease dispersion dynamics, especially if between patch mixing due to travel and migration is limited. In this paper, three levels of disease status in a - patch metapopulation was studied using a simple SIR-HIV epidemic model in a one dimensional nearest neighbour coupling lattice. The basic reproductive ratio , which is a function of coupling strength , is shown to affect stability characteristics of equilibrium points. The disease free equilibrium (DFE) is globally asymptotically stable irrespective of the value of but the stability of the endemic equilibrium point (EEP) depends on the coupling strength . It was found that at the critical value of coupling strength , the subpopulations dynamics are synchronized while for the subpopulation dynamics are independent. Patch isolation strategy for the control of HIV dispersion requires a critical coupling strength of . This interaction restriction reduces to values less than one, and the disease will be eliminated, making isolation effective. Demographic and epidemiological parameters of Vihiga County in Kenya were used in the study.</p>

Abstract
The consumption of poultry meat and eggs is expected to increase considerably in the nearest future, which creates the demand for new poultry feed ingredients in order to support sustainable intensive production. Moreover, the constant improvement of the genetic potential of poultry has resulted in an increased nutrient density in poultry feeds, which limits the possibility to include low quality feed ingredients. Therefore, the feed industry needs new sources of highly digestible protein with a desirable amino acid composition to substitute other valuable but limited protein sources of animal origin, such as fishmeal. With estimated 1.5 to 3 million species, the class of insects harbours the largest species variety in the world including species providing a high protein and sulphur amino acids content, which can be successfully exploited as feed for poultry. The aim of this paper is to review the present state of knowledge concerning the use of insect protein in poultry nutrition and the possibilities of mass production of insects for the feed industry. There is no doubt that insects have an enormous potential as a source of nutrients (protein) and active substances (polyunsaturated fatty acids, antimicrobial peptides) for poultry. It can be concluded, based on many experimental results, that meals from insects being members of the orders Diptera (black soldier fly, housefly), Coleoptera (mealworms) and Orthoptera (grasshoppers, locust, crickets and katylids), may be successfully used as feed material in poultry diets. However, legislation barriers in the European Union, as well as relatively high costs and limited quantity of produced insects are restrictions in the large-scale use of insect meals in poultry nutrition.

Abstract
The economic context in the recent years has undergone major changes in modern methods and techniques used in management. The current competitive environment is characterized by permanent turbulences influencing firstly the managerial act itself. Out of the many methods and techniques applied so far, some turn out to be less adaptable to the current economic and social context.
In the same train of ideas, the organizations always looking for sources of competitive advantage have the tendency of applying innovation and the new in the field. Another trend noted in the current management is that of going towards using operational management methods that enable the replacement of the current descriptive empirical management with certain regulatory and scientific methods.
From this point of view the study aims to highlight the competitive advantage generated by applying the participative management as a management method used within the organizations in order to obtain a better efficiency of the economic activities.
Different ways of seeing political depictions: A qualitative–quantitative analysis using Q methodology
Authors: Lobinger Katharina , Brantner Cornelia 
Published: March 2016

AbstractVisual depictions of politicians play an essential role in the impression formation of the audience because they convey visual cues and attributes related to, for example, likeability or competence. This study examines the subjective audience evaluations based on the visual portrayals of a politician by using Q methodology, a qualitative–quantitative approach of audience research. Q-sorts of 33 different pictures showing a high-ranking European politician, along with personal interviews, were used to probe the audience’s perception of a favorable or unfavorable picture. Q factor analysis yielded four groups of participants. The audience groups differ regarding their expectation toward favorably depicted political behavior and the involved balance of professional political leadership competences, social competences, and personality. In addition, technical and formal representation strategies were identified as important visual cues, but not for all audience groups.

AbstractINTRODUCTION: The maldevelopmental model of schizophrenia postulates pathological alterations in embryonal neurogenesis as the etiopathogenetic basis of schizophrenic psychoses. The neurotrophic factor hypothesis explains these neuropathological abnormalities as the result of alterations of the neurotrophin system caused by different mechanisms such as a genetic, infectious and traumatic factors. The tyrosine-kinase containing receptors trkB and trkC mediate growth-promoting effects of neurotrophins and respond to changes in neurotrophic factors availability. AIM: The aim of the present study was to establish the expression pattern of trkB and trkC in rat brain structures by a developmental model of schizophrenia. MATERIALS AND METHODS: On cryostat coronal brain sections of control and lesioned rats (after infusion of ibotenic acid solution bilaterally into the hippocampal formation), immunoreactions for trkB and trkC were performed. RESULTS: We found diminished expression of trkB and trkC in the hippocampal formation of lesioned animals compared to the controls. Quantitative measurements of immunohistochemical reactions intensity and statistical analysis confi rmed the reduced immunoreactivity for antigens under study (trkB and trkC) in the positive hippocampal neurons of 56-day-old lesioned rats compared to the control animals. CONCLUSION: The observed downregulation of neurotrophic factor receptors expression may compromise the function and plasticity of hippocampal formation in schizophrenic brains.

Abstract
Dapsone is a drug commonly used in the treatment of leprosy. In Europe it is rarely prescribed, mostly for the treatment of skin diseases such as dermatitis herpetiformis. Poisoning with dapsone is rare and reports of such cases are of interest for toxicological practice. We describe the only acute dapsone poisoning in a caseload series of 21000 intoxications treated in the Clinical Toxicology Clinic at St George University Hospital in Plovdiv, Bulgaria between 1999 and 2013.
We report on a 36-year-old woman who attempted deliberate self-poisoning with an ingestion of approximately 4.5 g of dapsone and 0.3 g of olanzapine. On admission, the patient was in a state of severe intoxication and comatose. On admission to hospital 9 hours after the ingestion, the methemoglobin level was 51.7%. The patient recovered 8 days later. She received complex treatment including intubation, ventilation, repeated gastric lavage, hemodialysis, blood exchange transfusion and antidote treatment with methylene blue. She was discharged in good clinical condition with minimal organ damage such as mild toxic hepatitis.

AbstractConflicts in healthcare settings are quite common events because of the continuous changes and transformations today’s healthcare organizations are undergoing and the vigorous interaction between the medical professionals working in them. AIM: To survey the opinions of medical professionals about the possible destructive effects of conflicts on them in the workplace. MATERIALS AND METHODS: We conducted a direct individual survey of 279 medical employees at four general hospitals. We used a set of questions that reflect the negative effects and consequences of conflict on healthcare professionals as direct or indirect participants. All data were analysed using the descriptive statistics and non-parametric analysis at a significance level for the null hypothesis of p < 0.05. RESULTS: Workplace conflicts contribute a lot to the stress, psychological tension and emotional exhaustion medical professionals are exposed to. The confrontation the conflict brings the participants into acts as a catalyst of the conflict and enhances the manifestation of hostile actions. A conflict generates a situation which has an impact on the behaviour of all participants involved in it giving rise to emotional states such as anger, aggression and reproaches. The destructive consequences resulting from a conflict are seen in the reduced work satisfaction and demotivation to perform the work activity. The contradictions that arise as a result affect negatively the team cooperation and obstruct the collaborative efforts in solving the problems in the healthcare setting. CONCLUSION: A conflict in a healthcare setting exerts a considerable destructive effect on an employee, therefore it requires prompt identification and effective intervention to minimise its unfavourable outcomes.
Splitting and survival probabilities in stochastic random walk methods and applications
Authors: Sabelfeld Karl K. 
Published: March 2016

Abstract
We suggest a series of extremely
fast stochastic algorithms based on exact representations we derive in this paper for the first passage time and exit point probability densities, splitting and survival probabilities. We apply the developed algorithms to the following three classes of problems: (1) simulation
of epitaxial nanowire growth, (2) diffusion imaging of microstructures, in particular, cathodoluminescence imaging for threading dislocations, and (3) simulation of the annihilation of electrons and holes in vicinity of nonradiative centers and quantum efficiency evaluation. In the last example the Random Walk on Spheres method is used to solve nonlinear diffusion equations,
and to more general systems of nonlinear Smoluchowski equations combined with the kinetic Monte Carlo method.
Precision of the Sinefitting-Based Total Harmonic Distortion Estimator
Authors: Alegria Francisco C. 
Published: March 2016

Abstract
An analytical expression for the standard deviation of Total Harmonic Distortion (THD) estimation is derived. It applies to the case where the estimator uses sine fitting. It is shown that, in common circumstances, it is inversely proportional to the actual value of THD, the signal-to-noise ratio and the square root of the number of samples. The proposed expression is validated both with numerical simulations and an experimental setup using a Monte Carlo procedure.
Analysis of Applicability of Flow Averaging Pitot Tubes in the Areas of Flow Disturbance

Published: March 2016

Abstract
The issues connected with the complex design of various facilities, including up-to-date boiler equipment as well as the ways of organizing the space around them, are the reasons why there is often a lack of room for mounting a flowmeter in accordance with the recommendations of manufacturers. In most cases the problem is associated with ensuring sufficient lengths of straight pipe leading into and out of a flowmeter. When this condition cannot be fulfilled, the uncertainty of measurement increases above the value guaranteed by the manufacturer of the flowmeter. This sort of operation problem has encouraged the authors of this paper to undertake research aimed at the analysis of applicability of averaging Pitot tubes in the areas of flow disturbance.
Analysis of the Extremely Low Frequency Magnetic Field Emission from Laptop Computers
Authors: Brodić Darko 
Published: March 2016

Abstract
This study addresses the problem of magnetic field emission produced by the laptop computers. Although, the magnetic field is spread over the entire frequency spectrum, the most dangerous part of it to the laptop users is the frequency range from 50 to 500 Hz, commonly called the extremely low frequency magnetic field. In this frequency region the magnetic field is characterized by high peak values. To examine the influence of laptop’s magnetic field emission in the office, a specific experiment is proposed. It includes the measurement of the magnetic field at six laptop’s positions, which are in close contact to its user. The results obtained from ten different laptop computers show the extremely high emission at some positions, which are dependent on the power dissipation or bad ergonomics. Eventually, the experiment extracts these dangerous positions of magnetic field emission and suggests possible solutions.
Interpolated-DFT-Based Fast and Accurate Amplitude and Phase Estimation for the Control of Power
Authors: Borkowski Józef , Kania Dariusz 
Published: March 2016

AbstractQuality of energy produced in renewable energy systems has to be at the high level specified by respective standards and directives. One of the most important factors affecting quality is the estimation accuracy of grid signal parameters. This paper presents a method of a very fast and accurate amplitude and phase grid signal estimation using the Fast Fourier Transform procedure and maximum decay side-lobes windows. The most important features of the method are elimination of the impact associated with the conjugate’s component on the results and its straightforward implementation. Moreover, the measurement time is very short ‒ even far less than one period of the grid signal. The influence of harmonics on the results is reduced by using a bandpass pre-filter. Even using a 40 dB FIR pre-filter for the grid signal with THD ≈ 38%, SNR ≈ 53 dB and a 20‒30% slow decay exponential drift the maximum estimation errors in a real-time DSP system for 512 samples are approximately 1% for the amplitude and approximately 8.5・10‒2rad for the phase, respectively. The errors are smaller by several orders of magnitude with using more accurate pre-filters.
