Do Multinational Companies Practice Good Corporate Governance? Empirical Evidence from Bangladesh
Authors: Wali Ullah G. M. , Ahmed Sarwar Uddin , Ahmed Samiul Parvez , Jamshed Kazi Md.
Published: November 2017

Corporate Governance refers to the way an organization is directed, administrated or controlled. It includes the set of rules and regulations that affect the manager's decision and contribute to the way company is perceived by the current and potential stakeholders. The corporate governance structure specifies the distribution of rights and responsibilities among different participants in the corporation such as; boards, managers, shareholders and other stakeholders and spells out the rules and procedures and also decision-making assistance on corporate affairs. Corporate governance practices in Bangladesh are gradually being introduced in most companies and organizations (Du, 2006). However, Bangladesh has fallen behind its neighboring countries and global economy in corporate governance (Gillibrand, 2004). Corporate governance structure is mainly considered ambiguous. Specific governance structures or practices will not necessarily fit all companies at all times. Firms with strong corporate governance mechanisms are generally associated with better financial performance, higher firm valuation and higher stock returns. Unfortunately, investors in Bangladesh have a little information about how these corporate values affect the performance of the Multinational Companies (MNCs). This study aims to provide a quantitative contribution to the literature by examining the impact of corporate governance mechanisms on financial performance from the perspective of MNCs. A panel data based Ordinary Least Squared (OLS) regression model was used to measure the quantitative significance of various corporate governance related variables on MNC performance, as identified through a detailed literature review.

FDI Inflow, Stock Market Performance and Exchange Rate: Indian Scenario
Authors: Kunal Kunal , Phani B V
Published: November 2017

In this research work, macro level analysis has been conducted to assess impact of foreign direct investment (FDI) capital inflow in Indian economy. This study is focused on causality relationship between FDI inflow, stock market performance and foreign exchange rate. This framework is used for policy implications of relationship between three variables. These macro-economic variables are linked with different policies. Causality tests performed on these variables are further used for policy implications. Impact of change in exchange rate on changes in FDI inflow is the least significant followed by impact of changes in FDI inflow on changes in sensitivity index of stock exchange (SENSEX). The third least significant relationship is observed between changes in FDI inflow on change in exchange rate. These relationships are implied to ‘Impossible Trinity’ framework to assess preference for monetary, fiscal and foreign exchange rate policies. It is observed that improving performance of stock market (SENSEX) should be on priority followed by exchange rate. These finding have implications on fiscal policy, monetary policy and exchange rate. The increase in return of stock market and favourable exchange rate will help in increasing FDI inflow in Indian economy. Stock market performance depends on daily transactions by investors and they are regulated only, not controlled. Supply of foreign currency in India is controlled by the Reserve Bank of India (RBI), who assesses the supply conditions of the market and attempts to manage exchange rate in favour of Indian economy. In other words, the exchange rate can be controlled by having control on supply of foreign currency in domestic market. Hence, there is possibility of having fixed exchange rate and target band of exchange rate.
Moderating Effect of Social Uncertainty between Capital Budgeting Practices and Performance
Authors: Kengatharan Lingesiya
Published: November 2017

Capital budgeting is crucial in order for companies to sustain themselves, survive and flourish in markets and to increase shareholders’ wealth. The performance of a firm depends on its effective investment decisions. Investing in the 'right' project has an influence on the success of the firm and its future growth. Even though risk and uncertainty factors carefully considered in investment decision making. Therefore, aim of this study was to evaluate the moderating effect of uncertainty between capital budgeting practices and performance based on Sri Lankan emerging market. The data were garnered from primary data and secondary data sources. The primary data were collected from 186 CFOs working in companies in Sri Lanka using self-administered questionnaires. The questionnaire was piloted with a sample of five CFOs. The secondary data were mainly collected from CSE via the Bloomberg website/annual reports for the 5 years period. In order to evaluate the moderating effect of uncertainty between capital budgeting practices and performance, social uncertainty has been considered in this study. Performance was measured by Tobin_q. Data were analysed using descriptive, inferential and multivariate analysis. Findings of the study revealed that an increased level of social uncertainty weakens the positive relationship between sophisticated capital budgeting practices and Tobin_q. In a similar way, an increased level of social uncertainty weakens the positive relationship between advanced capital budgeting practices and Tobin_q and vice versa. Overall, this study has made contribution as identified the moderating effect of uncertainty between the relationship of capital budgeting practices and performances. In a nutshell, beyond its valuable contribution, this study serves as a springboard for future research in many ways.
Corporate Governance and Cash Holdings: Empirical Evidence from an Emerging Country, Sri Lanka
Authors: Ajanthan Alagathurai , Kumara KGA Udhaya
Published: November 2017

This study examines the influence of corporate governance practices on cash holdings of Sri Lankan listed companies. It develops hypotheses about the relationship between cash holding and corporate governance practices such as size, frequency of meetings, independence, independent chair and gender diversity. Using multiple regression analysis on data collected from the corporate annual reports of 90 listed companies, the study finds that corporate governance practices such as board size and gender diversity have a significant negative influence on cash holdings as well as independent chair has a significant positive influence on cash holdings. However, there is no evidence that board meetings affect cash holding in Sri Lankan companies. The study contributes to the literature on the factors that make variation in the amount of cash holding of the listed company and it may be useful for financial managers, business analyst, financial controller, operations managers, investors, financial management consultants and other stakeholders.
The Role of the Information Society in Promoting a Better and a More Democratic Governance
Authors: Hijal Moghrabi Imane , Sabharwal Meghna
Published: November 2017

One of the major shifts that our society has witnessed in the past few decades is the paradigm shift from traditional bureaucracies to network arrangements in policy making and service delivery. This paper explores the New Governance as a paradigm shift in Public Administration with an emphasis on the democratic aspect of it. Approaching the New Governance from an Open Systems Theory perspective, this paper argues that the advent and the widespread use of ICTs and the “infosphere” – and the “information society” that has emerged from it – would help in promoting a better and a more democratic governance by providing new channels to put democracy into practice. This paper also acknowledges the dark side of the “infosphere” and the ethical challenges that have come along with it.
Financial Distress Risk and Momentum Effects: Evidence from China’s Stock Market
Authors: Wang Qian
Published: November 2017

I examine the relation of distress risk to size, book-to-market, and momentum effects in China’s stock market. Consistent with the market underreaction hypothesis, I find that distressed firms underperform non-distressed firms in China’s stock market and the momentum factor proxies for distress risk in our sample period. My study also shows that the explanatory power of the momentum effect is subsumed when the distress factor is present.

Published: November 2017

Tem por objetivo analisar a importância das cidades médias de Araguaína, Gurupi e Palmas no Tocantins, tendo como recorte analítico os processos de concentração econômica e espacial nelas verificados vis-à-vis as demais cidades do estado. Para tanto, na primeira seção levantamos argumentos em favor dos processos de desconcentração econômica e espacial do território brasileiro a partir de 1970. Em seguida, tratamos da formação e crescimento das cidades médias do Tocantins, para, finalmente, entrarmos no objetivo central deste trabalho, ou seja, os papéis das cidades médias tocantinenses. Pudemos constatar que, com a ausência de metrópoles no Tocantins, são as cidades médias que assumem o protagonismo socioeconômico, atraindo os principais investimentos e comandando a rede urbana, de um lado, polarizando um conjunto amplo de centros locais e pequenas cidades, pela oferta de bens e serviços especializados e diversificados, de outro, estabelecendo amplas interações espaciais com o espaço nacional e internacional.
Os desafios postos ao Relatório do Desenvolvimento Humano de 2009 pelos processos migratórios atuais
Authors: Rezende Maria José De
Published: November 2017

O Relatório do Desenvolvimento Humano (RDH) do ano de 2009 tem como tema os desafios que os processos migratórios põem na atualidade a todos os Estados nacionais e a todos os indivíduos que se deslocam de suas regiões de origem para outros destinos em busca de melhores condições de seguridade humana. Os elaboradores e encampadores dos RDH constroem inúmeros diagnósticos e prescrições ao sugerirem, aos Estados, à sociedade civil e aos organismos internacionais, políticas de diminuição do sofrimento social pelo qual passam estas pessoas. Considera-se que as prescrições deste RDH têm sido confrontadas tanto pelo modo como tem aumentado nos últimos anos o número de pessoas que tentam refugiar-se em outros países fugindo de guerras, miserabilidades, fome e todo tipo de inseguridade humana, quanto pelo acirramento de políticas de recusa de recebimento, bem como pela disposição crescente, por parte de lideranças políticas, de militarizar a agenda migratória.

Authors: Dzingutė Agnė , Pileičikienė Gaivilė , Baltrušaitytė Aušra , Skirbutis Gediminas
Published: November 2017

Background. The aetiology of temporomandibular joint disorders (TMD) is multifactorial, whereas occlusal disharmony is one of the predisposing factors. Researchers still discuss the relation between occlusion and TMD.
Objective. The study aims to investigate the relation between static occlusal parameters and TMD clinical symptoms using T-Scan II analysis system.
Material and methods. The sample consisted of 44 persons divided into the treatment group of 20 TMD patients and the control group of 24 subjects without TMD. The main task of T-Scan II computerized occlusal analysis system was to record every patient’s occlusion and estimate static occlusal parameters: centre of occlusal force, asymmetry index of maximum occlusal force and occlusion time. These results were compared between groups, data related to patients’ complaints and clinical symptoms. The analysis was carried out using Mann-Whitney U, Kruskal-Wallis and Chi-square tests.
Results. Averages of the centre of occlusal force in TMD subjects were 6.55 ± 0.99 mm, in the control group – 5.88 ± 0.69 mm; the asymmetry index of maximum occlusal force averages: 15.90 ± 2.71 and 12.93 ± 1.88; occlusion time: 0.281 ± 0.036 s and 0.236 ± 0.022 s, respectively. There were no statistically significant differences between two groups but they were found in the centre of occlusal force and the asymmetry index in the two groups (p < 0.05).
Conclusions. There exists a relation between complaints of patients with TMD and static occlusion parameters. Values of the centre of the occlusal force distance and the asymmetry index of occlusal force in TMD patients with pain in the temporomandibular joint (TMJ) were significantly higher than in the control group.

Published: November 2017

Stroke is the third most common cause of death in the developed world and the leading cause of adult disability. The goals of an imaging evaluation for acute stroke when presented with patients with raised clinical suspicion of an acute stroke are to obtain accurate information about the momentary state of brain tissue. A comprehensive evaluation is best achieved with a combination of computed tomography or magnetic resonance imaging technique. Unenhanced computed tomography and magnetic resonance imaging can help rule out hemorrhage and identify early morphologic signs of acute brain ischemia. Computed tomography and magnetic resonance perfusion imaging and magnetic resonance diffusion weight imaging, can help depict unsalvageable ischemic brain tissue and the area of penumbra. Computed tomography angiography and magnetic resonance angiography are widely used techniques for assessment of both, the intracranial and neck circulation.

IntroductionThe influence of polyacetal wear particles on aseptic loosening of non-cemented isoelastic femoral stems with polyacetal coating remains unclear. The aim of our study was to use nuclear methods to prove the presence of polyacetal wear particles, to determine their morphology and to check their distribution in the tissues around loosend hip prosthetic components.MethodsTissue samples obtained during retrieval of 4 aseptic loosened primary hip prostheses with isoelastic stems made of polyacetal were subjected to nuclear analyses. Proton microbrobe method (mikro-PIXE) was used to prove the presence of polyacetal wear particles and to check for their morphology by detection of barium, which is molecularly in BaSO4 embedded in polyacetal. Thermal neutron activation was used to determine distribution pattern of polyacetal wear in the peri-prosthetic tissues.ResultsAgainst expectations, polyacetal wear particles were found rather rare, larger than 100 µm and present in pseudo-membrane samples around the loosened stem, but virtually absent in tissues away from their origin. Concentration of BaSO4 in polyacetal wear particles in pseudo-membrane samples was similar to the one in polyacetal coating (conc. Ba = 14217 µg/g and 14800 µg/g, respectively).ConclusionAccording to the results, the primary cause of the loosening of the isoelastic stems with polyacetal coating is most probably mechanical restlessness, which is responsible for local production of the large polyacetal wear particles responsible to accelerate the process of loosening. PIXE method and thermal neutron activation are sensitive quantitative nuclear methods suitable for direct or indirect detection of wear particles in the tissue around loosened prostheses and to determine morphology of wear particles and their distribution in the tissues.

Published: November 2017

Introduction:In our study, our aim was to reveal the relationship between subendocardial hemorrhage (SEH)  which can be seen macroscopically immediately beneath the endocardium, and emerge secondary to many conditions from direct cardiac,  head, and abdominal traumas to hyperemia, and its location with cause of death, its diagnostic value (if any), and whether it can be evaluated as a vital finding.Material and Method :285 autopsy cases diagnosed as SEH which were brought to the Group Presidency of Morgue Specialization Department of the State Institute of Forensic Medicine of Bursa  were included in the studyResults: Study population consisted of 229 (80.4 %) male, and 56 (19.6 %) female patients. Thity-one cases of death were related to natural causes, while the most frequently detected pathological causes of death were isolated abdominal traumas (32.9 %), followed by isolated head traumas (31.9 %).  While traffic accidents ranked first (35.1%) among the events leading to death. Among evaluated cases, SEH was mostly located on septum.Discussion: To fully understand the yet inadequately elucidated pathogenic mechanisms  of SEH , it should be accurately defined by histopathological analysis. Even though various causes of death seen  in association with these lesions suggest more than one underlying pathogenic mechanism, because of their nonspecific characteristics, their possible roles as indicators of vitality (if any) should be reinforced  by further studies.

Glucocorticoids have been used in clinical medicine since 1940s. Despite the time-long use they are still a subject of active ongoing research. We describe the mode of action, pharmacology and side effects to enable proper prescription of these drugs. Glucocorticoids exert genomic and non-genomic effects, the latter become important at higher doses. The nomenclature of dosage ranges and the principles of dosage adjustments are given. Glucocortioid use is associated with frequent and important side effects in numerous organ systems. Prophylactic treatments for osteoporosis and infections are described. The suppression of hypothalamic-hypophyseal hormonal axis determines the need for gradual glucocorticoid withdrawal and supplementation after discontinuation. Finally, glucocorticoid withdrawal syndrome is described.

Background: In the last decades outcomes of rectal cancer treatment are improving due to better understanding of tumor biology, neoadjuvant and adjuvant treatment and precise surgical technique, considering pathologic anatomical lines. Proportion of rectal cancer local recurrence (LR) has been substantially decreasing. Objectives of this study are, first, to find out whether two groups, with and without rectal local recurrence, are statistically important different in certain risk factors and, second, to define prognostic factors of rectal local recurrence.Methods: Total of 787 nonmetastatisc rectal cancer patients, diagnosed between 2003 and 2005, treated with surgery in all Slovenian hospitals, were enrolled retrospectively. The recurrence-free survival rates were calculated with Kaplan-Meier method. For statistical comparison of survival of two groups according to prognostic factors log-rank test was used. The adjusted hazard ratios for significant survival prognostic factors were calculated using Cox multivariate analysis.Results: Patients with LR had more tumors in the lower third of rectum (p=0,045), more abdominoperineal, Hartmann's and local excisions (p=0,000) and less radical operations (p=0,005), more of them were operated in hospitals with lesser caseload of patients (p=0,000), more often were treated only surgically (p=0,048), had more colon defects after excision of tumors (p=0,025) and had more distant disease recurrences (p=0,000). In follow up period of 5,3 years LR occurred in 13,1% and in 54% of those in 1,9 years after surgery. In the multivariate analysis, the statistically significant prognostic factors for recurrence-free survival were tumor's rectal position, regional lymph nodes status and the hospital of surgery.Conclusions: Proportion of LR is an appropriate indicator of optimal multidisciplinary rectal cancer treatment.
FEMOROPOPLITEALNI OBVOD Z UPORABO ENDOSKOPSKE METODE
Authors: Požar Ingrid , Špan Matjaž
Published: November 2017

Femoropopliteal bypass is a surgical procedure used in the advanced stages of peripheral arterial disease on lower limb arteries. The most common cause of arterial peripheral disease is the atherosclerotic plaque, which significantly narrows the vascular lumen. This kind of lesion is treated with vascular interventions. Those are divided into endovascular percutaneous interventions and into classic surgical interventions. In addition there is emerging a new endoscopic method in vascular bypass operations as an alternative to the already existing classic surgical intervention. Endoscopic vein harvesting is a minimally invasive surgical technique that enables vein dissection and its usage for vascular bypass with the help of videoscopic equipment. The case report presents a 68-years old male with diagnosed peripheral arterial disease. He was a suitable candidate for surgical treatment, therefore a femoropopliteal bypass was done in his right lower extremity. The distinctive note of this operation was the usage of anewer technique, that is, endoscopic vein harvesting of the greater saphenous vein.

Amyotrophic lateral sclerosis (ALS) is a rare complex neurodegenerative disease characterized by degeneration of motor neurons in the cerebral cortex, brainstem and spinal cord. The disease mainly occurs in adults, typically between 50. and 60. years and presents with symptoms like muscular weakness, atrophy and later on paralysis which lead to death due to respiratory failure within 2-5 years from onset and remains incurable. The symptoms typically start in the muscles of arms or legs (spinal onset) or bulbary (bulbar onset). Most ALS cases are sporadic although about 5% are familiar. Genetic factors contribute to the disease in sporadic form as well as in familial form. Mutations have been found in 116 genes among which SOD1, TARDBP, FUS and C9ORF72 are represented in highest frequencies. Besides those four genes we are also describing 13 other genes involved in the disease process. Oligogenic model has been proposed for ALS that considers mutations in two or more genes in one patient. We emphasize the convergence between hereditary and sporadic form, which are clinically inseparable, and other neurodegenerative diseases that share with ALS genetic and clinical characteristics. Because about 2/3 of familial cases and only about 11% of sporadic cases are explained by mutations the research have been aimed at discovering new candidate genes using  genome –wide association studies and at the epigenetic causes of the disease. We have recently completed the first representative genetic analysis of patients with ALS in Slovenia and research on methylation and microRNAs is currently in progress.

Background: Well-educated and highly-trained physicians are an essential part of high-quality health care. Therefore, quality assurance in medical education must be one of the priorities of health systems. We researched and analysed responses from physicians after completion of internship (IS) and their mentors to questions regarding preparedness to IS and IS itself.Methods: In this cross-sectional study electronic surveys were sent to 298 physicians, having completed the IS between February 2014 and February 2015, and to their 200 mentors. Ordinal reponses of two independent groups were compared by Mann-Whitney-U test, while Kruskal-Wallis test was used for comparing more than two groups. Frequency distributions of practical procedures that were completed by interns in required quantities were compared between institutions by χ²-test. The same test was used for comparing frequency distributions of binary responses between clinical departments.Results: Statistically significant differences were found in the following: in reported preparedness for IS between graduates of the two Slovenian medical faculties; in realisation of practical procedures in quantities as prescribed in the IS program between different health institutions; in agreement with statements about satisfaction between different clinical departments and different institutions; and in reported active participation in patient care between different clinical departments.Conclusions: In this study we identified differences in phisicians' preparedness for IS between the graduates of the two Slovenian medical faculties, as well as differences in realization of IS program between health institutions and clinical departments. Alongside presented descriptive statistics these data allow evaluation of the current quality of IS in Slovenia. Furthermore, the results of this study will permit assessment of quality improvement after realisation of planned IS program renovation.

Contact lenses are freely available without professional examination and fitting, as well as without adequate introduction and instructions on handling, disinfection and storage. Contact lenses may have physiological, metabolic and anatomic effect on the eyes, which is manifested both on the eyelids, lacrimal film, conjunctiva and in all layers of the cornea - the epithelium, stroma and the endothelium. We can see these complications too often at our everyday work. The purpose of this paper is to draw attention to the potential complications due to inappropriate use of contact lenses.Contact lenses are otherwise a safe and effective method of correcting visual acuity; they are also useful for therapeutic purposes. Complications related to contact lenses wear could be largely avoided with an appropriate professional approach and the compliance of contact lens wearers. It is important to discuss with patients their medical history, their desires and expectations, their working and living environment; followed by professional examination of patients and appropriate fitting of contact lenses. Patients should receive detailed oral and written instructions and be subscribed to regular checks. But unfortunately, all this is not enough, if patients do not comply every day with given instructions.

Transcatheter aortic valve implantation for bicuspid aortic valve stenosis: Acute and intermediate-term outcomes in a high volume institution
Authors: Djordjević Anže , D'Ancona Giuseppe , Unbehaun Axel , Kische Stephan , Ince Hüseyin , Pašić Miralem
Published: November 2017

Background: We report our experience with transcatheter aortic valve implantation (TAVI) in patients with bicuspid aortic valve (BAV) stenosis.Methods: Perioperative and intermediate-term follow-up data were retrospectively analysed. All procedures were performed within the premises of an experienced high-volume TAVI centre.Results: Tirty-three consecutive BAV patients (age 55 to 87 years) underwent TAVI. Mean logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) was 23,2 ± 19,3. Transapical Edwards Sapien® valve was implanted in the majority of patients (87.9 %). Nine patients (27.3 %) required post-ballooning of the implanted valve for moderate to severe paravalvular leak, 3 patients (9 %) required a second valve implantation for persistent severe paravalvular leak, and 2 (6 %) required conversion to conventional surgery. Post-operative mild aortic regurgitation (AR) was presented in 12 patients (36.4%) and AR = 2 in 3 %. No AR > 2 was observed. Te device success rate according to the valve academic research consortium (VARC) criteria was 82 %. Similar BAV anatomy, calcium distribution, type and size of implanted valve were noticed in patients with and without residual AR. Tere was no thirty-day mortality. Two-year estimated survival was 70 % (CI: 52.7–93.1) and was similar in patients with and without post-procedural residual paravalvular leak.Conclusions: TAVI in BAV stenosis is feasible but, even in experienced centres, is technically more challenging and is associated with a higher rate of post-dilatation, re-valving, and conversion to conventional surgery. Results should be re-tested in light of the recent introduction of second-generation TAVI prostheses.

The impact of open access on the medical literature: a review of current literature
Authors: Turk Nana
Published: November 2017

Background: the aim of the article is to conduct an overview of the impact of OA on the medical articles based on 3-part categorization.Methods: Data were identified by a search strategy with eight combinations of keywords (open access, citation impact, citation advantage, citation count, article download, article usage, social media attention, altmetrics) and searched in three diﬀerent databases.Results: the analysis was conducted on 107 studies dealing with citations, downloads and social impact. Sixty-seven of them simply employed the counting citations to OA and non-OA articles; nineteen articles compared the downloads and citations counts; and twenty-one articles investigated the social impact of OA articles. Twenty-five articles investigated the citations, download counts, and social impact of medical articles.Conclusions: The studies investigating the citation impact mostly showed citation advantages. Those that employed citation and download counts of medical articles using randomized controlled trials showed that OA articles were downloaded significantly more frequently, but found no evidence of a citation advantage for open access articles. The citation advantage from open access might be caused by other factors. Results of the studies comparing the social media attention and citations/downloads of the medical articles are often diametrically opposed.
Data Visualization on Information Tables - Dashboards

Published: November 2017

Today’s level of the information technology development allows gathering of large amount of data relevant for a company. The issue of way and method of data gathering has been solved, however, at the same time the need also arises for extraction of the most important ones, since the quantity of the input data itself is not enough. In the contemporary business activities, being pursued in the circumstances of high competition, changes, speed and risk, management of the company may be compared to driving a fast car. Therefore, the information tables - dashboards have been created for the purpose of data processing as an analogy to the car dashboard, which, by means of several indicators, provides for the driver an instant insight into various data related to driving and the engine running. Display of the data in the form of charts and diagrams undoubtedly helps in obtaining new knowledge however, an individual visual displaying is seldom sufficient thus they should be combined in different variants. The work presents concrete examples of the dashboards creation both locally and globally.

Published: November 2017

Customer Relationship Management (CRM) has become more and more a key strategy for large and small businesses. It supports marketing, sales, services and involves direct and indirect customer interaction. Customers are put into the center of the business, because they represent an asset and profit for any company. Customers need to be satisfied in order to be loyal. A company can achieve that by meeting customer’s needs and expectations. In order to perform both for the benefit of the customer and for itself, a company has to use all the positive advantages of IS technologies that support CRM including data warehouses and data mining, that are clearly presented in this paper

Face recognition algorithm Principal Component Analysis (PCA) has a significant performance drop when comparing photographs taken from different angle. In this paper a 3D model was used for improving that performance. Model enables us to transform the face image which is taken from certain angle to en face. Model has been tested against biometric database formed at the Faculty of Organizational Sciences. Image rotation based on the model was performed before matching with the en face images from the database. Study results show that algorithm precision on biometric verification and identification has been seriously improved.

Published: November 2017

The air cooling systems are shown to be used to provide required temperature condition of traction induction motors on locomotives. The automatic temperature regulation system is developed for its using to solve such a task. Results of experimental investigation showed that the AO63-4 induction motor stator end winding on the side opposite to air supply is the most heated part of the induction motor. Based on the results of the research, it was used an aperiodic second-order transfer function for approximation of the thermal transient curves. The design of an induction motor control system maintaining operating mode with minimum of the stator current are considered. It is shown that the modes of minimum of the stator current and minimum of power losses are quite close to each other. The MatLab simulation results taking typical nonlinearities and iron power losses in an induction motor and conduction and commutation power losses in semiconductors of frequency converter into account are presented. It is shown that as a result of application of the suggested system the power losses reduction may be led up to 20 % relatively to classical scalar control.
Cluster formation techniques in hierarchical routing protocols for Wireless Sensor Networks

Published: November 2017

Abstract: Wireless sensors are an irreplaceable link in the chain of global networking today. There is almost no area of human activity where they are still not used, and they will be used in the near future almost everywhere. Wireless sensor networks consist of a large number of sensor nodes that are arranged (usually randomly) in an area. The main problem is the limited power supply. Sensors are usually powered by the battery which is not possible to replace. The lifetime of the network depends on the duration of battery power of sensor nodes. The largest part of the consumed energy goes for communication with the rest of the network. Therefore, the selection of good routing protocol is essential for the long life-span of the network. There are a large number of proposed protocols and they can be divided into several groups, depending on the approach to the problem. In this paper we present a family of hierarchical protocols, their common features and specific implementation, we will present advantages and disadvantages as well as possible directions of further development.

Published: November 2017

The paper presents the results achieved during the process of nickel removal from aqueous solutions by adsorption on alumina (Aluminum oxide) in continuous conditions. The continuing experiments were conducted in a glass column with diameter of 16 mm and fixed bed of adsorbent with quantity ranging from 30 to 115 g, adsorbent grains size from 1.0 to 2.0 mm, and retention time of 0.5 to 12 minutes. The quantity of nickel in the aqueous solutions was changed within the range of 0.045 up to 0.12 mg/l Ni. The analysis of the obtained experimental data defined the mutual affection of the retention time, the initial nickel concentration in the water, and the adsorbent quantity, i.e. the content of the adsorbent in the treated solution to the adsorbent capacity.According to the achieved results, logarithmic mathematical model showed best correlation between experimental and calculated values, also maximum nickel ions adsorption uptake onto the alumina were determined as 400 mg/g.

Published: November 2017

Edible plant oils, including sunflower oil, with high content of unsaturated fatty acids, are subject to hydrolytic and oxidative deterioration during storage. This study investigates the impact of packing material, clear uncoloured glass bottles and clear uncoloured polyethylene terephthalate (PET) bottles, in which the refined sunflower oil was packaged, and impact of storage conditions, on the speed of oil deterioration. Oil was filled in the bottles, hermetically sealed and kept in a dry place, at room temperature, and illuminated by artificial light. Results of the oxidative stability of sunflower oil assessment during six month storing in controlled conditions, showed that photo-oxidation adversely has an affect on product quality characteristics and coses forming of primary oxidation products. Peroxide number in oil, immediately after bottling was 0,230 mmol O2/kg oil, while after 6 months of storage value reached 7,800 mmol O2/kg oil (in glass bottle), and 8,600 mmol O2/kg oil (in PET bottle). Anisidine number in oil immediately after bottling was 5,5 and after 6 months of storage in a glass bottle it was 39,6 and 57,40 when oil was packaged in PET bottle. Averages of total oxidation values in sunflower oil packed in glass and PET packaging increased from 5,5 (immediately after bottling) to 55,20 in oil packaged in glass bottle, and 57,40 in oil packaged in PET packaging. The other results obtained in the paper confirmed the need for protecting sunflower oil against oxidative spoilage during storage, providing packaging in colored packages and storing on dark, dry place.

Published: November 2017

The study of equilibria established in cadmium bromide complexes solutions was performed voltammetrically, by applying the linear sweep technique on the hanging mercury drop electrode, HMDE. In the studied systems the initial cadmium-ion concentration was equal, and the concentration of ligands, bromide ion, was gradually increased along with maintaining the pH-value and ion force of the solution at the constant values. The resulting shifts of the voltammogram peak reduction potential, which come as a result of the change in the electroactive species concentration due to the increase of the ligand concentration, were treated by the method of  DeFord-Hume. In this manner four cadmium bromide complexes species were detected and their stability constants were determined. All obtained stability constants matched the literature data in a satisfactory manner.
