Authors: Mulasi Sebro 
Published: July 2018

Supplier selection process was become important consideration to improve the efficiency of procurement department because the raw material cost could reach 70% of product cost. The supplier selection process was multi-criteria problem involving qualitative and quantitative factors. The company often experienced shortage of good quality tamarind with a cheap price which companies often reject order from customers. Therefore the company should make a selective supplier selection and allocation of orders for optimum results by considering both qualitative and quantitative factors that can minimize the cost of purchase, maximizing the weight of suppliers and minimize the total defect order. This research will integrate supplier weight from Fuzzy Analytic Hierarchy Process and Goal Programming model for the final decision of supplier selection and allocation of orders. By running goal programming model give solution better than order allocation current model where it could reduce total cost of purchasing at Rp 130.000.000 to Rp 127.700.000 and reduce total of defect order at 4% to 0,87%.

Magnetorheological Self-Powered Vibration Reduction System with Current Cut-Off: Experimental Investigation
Authors: Jastrzębski Łukasz , Sapiński Bogdan 
Published: July 2018

Abstract
The paper summarises the results of laboratory testing of an energy harvesting vibration reduction system based on a magne-torheological (MR) damper whose control circuit incorporates a battery of bipolar electrolytic capacitors (current cut-off circuit). It is de-signed to reduce the undesired effects in vibration reduction systems of this type, associated with the increasing amplitude of the sprung mass vibration under the excitation inputs whose frequency should exceed the resonance frequency of the entire system. Results have demonstrated that incorporating a current cut-off circuit results in a significant decrease of sprung mass vibration amplitudes when the frequency of acting excitation inputs is higher than the resonance frequency.

Published: July 2018

Abstract
The aim of the present paper is to examine both the fatigue behaviour and the phase transition mechanisms of an equiatomic pseudo-elastic NiTi Shape Memory Alloy through cyclic tests (up to 100 loading cycles). More precisely, miniaturised dog-bone specimens are tested by using a customised testing machine and the contents of both austenite and martensite phase are experimentally measured by means of X-Ray diffraction (XRD) analyses. On the basis of such experimental results in terms of martensite content, an analytical model is here formulated to correlate the stress-strain relationship to the phase transition mechanisms. Finally, a validation of the present model by means of experimental data pertaining the stress-strain relationship is performed.
Butt Welding of Round Drive Belts
Authors: Wałęsa Krzysztof , Malujda Ireneusz , Talaśka Krzysztof 
Published: July 2018

Abstract
The on-going rapid development of industry encourages development of new production technologies and designing of machines that use inventive mechanical engineering solutions, a big demand for parts of such machines being a natural consequence. Polymeric power transmission belts are a good example of that. This paper proposes an improvement in the process of production of such belting. Their production includes cutting to length and splicing of elastic round belts to obtain endless belts of the specified length. This is the key phase of the whole production process. A number of splicing methods are available using different physical phenomena. One of them is butt welding technique. In this process heat is applied on the material through an additional heating element called the heat platen. The effect depends on several factors, including preparation of the work pieces. Due to its characteristics the process is often carried out by hand. The need for automated manufacturing was created by important factors associated with manufacturing on an industrial scale: cost, time and quality. The proposed butt welding machine, complete with a control system is an answer to this need. The practical benefits include improved repeatability of splices, time savings and less work load for the operator.

Authors: Gursky Volodymyr , Kuzio Igor 
Published: July 2018

Abstract
The two-mass resonant vibro-impact module is presented as the rod system with cylindrical intermediate supports. The corresponding design diagram is constructed. Based on the finite element method, the frequency of free oscillations is defined for the corresponding location of the intermediate supports. A stress-strain state of the elastic element is considered. The stiffness of the intermediate supports is defined by solving the contact problem between the cylindrical rod supports and the flat spring. The dynamics of the vibro-impact rod system with multiple natural frequencies is analyzed taking into account the contact stiffness of the intermediate supports. The determination of contact and equivalent stresses occurring during the operation of the vibro-impact rod system is performed.
Genetic Algorithm for Mobile Robot Route Planning with Obstacle Avoidance
Authors: Kwaśniewski Konrad K. , Gosiewski Zdzisław 
Published: July 2018

Abstract
Nowadays many public and private institutions begin space studies projects. Among many problems to solve there is a planet exploration. Now rovers are controlled directly from the Earth, e.g. Opportunity. Missions must be planned on the Earth using simulators. Much better will be when the mission planner could set the target area and work to do and the rover will perform it independently. The solution is to make it autonomous. Without need of external path planning the rover can cover a much longer distance. To make autonomous rovers real it is necessary to implement a target leaded obstacle avoidance algorithm. Solutions based on graph algorithms use a lot of computing power. The others use intelligent methods such as neural networks or fuzzy logic but their efficiency in a very complex environment is quite low. This work presents an obstacle avoidance algorithm which uses the genetic path finding algorithm. The actual version is based on the 2D map which is built by the robot and the 2nd degree B-spline is used for the path model. The performance in the most cases is high using only one processor thread. The GA can be also easily multithreaded. Another feature of the algorithm is that, due to the GA random nature, the chosen path can differ each time on the same map. The paper shows the results of the simulation tests. The maps have the various complexity levels. On every map one hundred tests were carried out. The algorithm brought the robot to the target successfully in the majority of runs.
The Impact of Non-Parallelism of Toothed Gear Shafts Axes and Method of Gear Fixing on Gearbox Components Vibrations
Authors: Wojnar Grzegorz , Juzek Michał 
Published: July 2018

Abstract
The subject of the experimental research was a modified back-to-back test stand. During the test, the driven gear with a number of teeth z1=16 was fixed on stationary axis. The tested gearbox worked without load and the closing gearbox was dismantled to avoid any additional vibration and noise. A mechanical system was also used which, during the tests, allowed to change the position of the above mentioned stationary axis. Gear with number of teeth z1 was fixed on a stationary axis with the arrangement of two self-aligning ball bear-ings which prevented significant changes in the angular position of axis of gear in regard of stationary axis; or fixed on a stationary axis with the arrangement of one self-aligning ball bearing which allowed significant changes in the angular position of axis of gear in regard of stationary axis. On the basis of the conducted studies, it can be stated that only in some of the analyzed cases fixing of gear with the arrangement of one self-aligning ball bearing reduces the vibration of the gearbox elements.

Abstract
The habitat selection by animals depends on different environmental and anthropogenic factors such as the season, climate, and the life cycle stage. Here, we have presented the summer habitat selection strategy of reindeer (Rangifer tarandus) in the unprotected forest area from the northern arctic region of China. In summer 2012, we investigated a total of 72 used and 162 non-used plots in the reindeer habitat to record habitat variables. We found that the reindeer used significantly higher altitude, arbour availability, and vegetation cover area as compared to the non-used habitat variables. Principal component analysis (PCA) showed that six principal components (68.5%) were mainly responsible for the summer habitat selection of reindeer such as the slope position, concealment, anthropogenic dispersion, arbour species, distance from the anthropogenic disturbance area (> 1000 m) and water quality (Wilks’ Lambda = 0.12; P = 0.0001). The local people are largely dependent on forest product resource in these regions, such as bees herding, collecting wild vegetables, hunting, poaching, and grazing. These activities highly influenced the reindeer habitat and its behaviours. This study thus confirmed that reindeers are forced to choose poor habitat in unprotected forest area with high human disturbance or interference. These factors should be considered by the concerned authority or agency to manage reindeer population in the wild.

Authors: Tomaszewska Ewelina Julita , Florea Adrian 
Published: July 2018

Abstract
This article aims at identification of the main trends in scientific literature characterising urban smart mobility, on the basis of bibliometric analysis of articles published in the ISI Web of Science and Scopus databases. The study period was set from 2000 to 2017. Authors used a basic technique of the bibliometric analysis of the scientific literature characterising urban smart mobility with the support of the VOSviewer software. The analysis included the number of publications, citation analysis, research area analysis and the most frequent keywords. The analysis led to taking notice of current research trends dealing with the urban smart mobility. The core of the paper is a theoretical framework of research trends, which was developed through a review of scientific literature. The result of this paper is a map showing the existing relationships between key terms, research areas characterising publications dealing with the urban smart mobility and intelligent transport system (ITS). “Smart city” is probably the most “in vogue”, debated and analysed concept among researchers and administrative/ governmental representatives from all over the world. This multidimensional concept is mainly based on smart technology structured around few major components: smart mobility, smart environment, smart governance, smart living, and everything that targets the people’s wellbeing. This work focuses on a hot topic – mobility because of its significant impact on the environment by pollution as well as living by requiring intelligent transport systems.

Authors: Böhmová E. , Čonková E. , Sihelská Z. , Harčárová M. 
Published: July 2018

Abstract
Yeasts from the genus Malassezia belongs to normal commensal skin flora of warm-blooded vertebrates. These yeasts may act as opportunistic pathogens and cause skin diseases in humans and animals under certain conditions. The identification of Malassezia species is based on the phenotypic or genotypic diagnostics. The methods used for the phenotypic identification is determined by: the growth on Sabouraud agar, growth on selective media (Leeming-Notman agar, Dixon agar, Chrom Malassezia agar), the ability to utilise different concentrations of Tween, monitoring of the growth on CEL agar (soil enriched with castor oil) and TE agar (Tween-esculine agar), and the catalase test. The genotypic identification uses molecular methods like: the pulsed field gel electrophoresis (PFGE), random amplified polymorphic DNA (RAPD), amplified fragment lenght polymorphism (AFLP), denaturing gradient gel electrophoresis (DGGE), and the DNA sequence analysis.
Spinal Cord Injuries in Dogs Part II: Standards of Care, Prognosis and New Perspectives
Authors: Šulla I. , Balik V. , Horňák S. , Ledecký V. 
Published: July 2018

Abstract
Severe spinal cord injuries (SCI), causing physical handicaps and accompanied by many serious complications, remains one of the most challenging problems in both, human and veterinary health care practices. The central nervous system in mammals does not regenerate, so the neurological deficits in a dog following SCI persists for the rest of its life and the affected animals display an image of permanent suffering. Diagnostics are based on: neurological examination, plain x-rays of vertebral column, x-rays of the vertebral column following intrathecal administration of a water-soluble contrast medium (myelography), x-rays of the vertebral column following epidural administration of a contrast medium (epidurography), computed tomography (CT) and/or magnetic resonance imaging (MRI). Currently, only limited therapeutic measures are available for the dogs with SCIs. They include: the administration of methylprednisolone sodium succinate (MPSS) during the acute stage; early spinal cord decompression; stabilisation of vertebral fractures or luxations; prevention and treatment of complications, and expert rehabilitation. Together with the progress in the understanding of pathophysiologic events occurring after SCI, different therapeutic strategies have been instituted, including the local delivery of MPSS, the utilisation of novel pharmacological agents, hypothermia, and stem/precursor cell transplantation have all been tested in the experimental models and preclinical trials with promising results. The aim of this review is the presentation of the generally accepted methods of diagnostics and management of dogs with SCIs, as well as to discuss new therapeutic modalities. The research strategy involved a PubMed, Medline (Ovid), Embase (Ovid) and ISI Web of Science literature search from January 2001 to December 2017 using the term “spinal cord injury”, in the English language literature; also references from selected papers were scanned and relevant articles included.
Gender-Related Particularities in Acute Myocardial Infarction – a Study on a Patient Cohort from North East Romania
Authors: Anghel Larisa , Prisacariu Cristina , Georgescu Cătălina Arsenescu 
Published: July 2018

Abstract

Introduction: Cardiovascular disease is the leading cause of death among women irrespective of race or ethnicity, and about half of these deaths are caused by coronary artery disease. Several studies have reported that cardiovascular diseases manifest themself with a delay of about 7–10 years in women and that they have higher in-hospital mortality. It has not yet been established whether female gender itself, through biological and sociocultural differences, represents a risk factor for early in-hospital mortality in ST-segment elevation acute myocardial infarction (STEMI). The aim of our study was to identify the angiographic particularities in women with STEMI from North East Romania.

Material and Methods: For one year, 207 (31.7%) women and 445 (68.3%) men diagnosed with acute myocardial infarction were hospitalized in the Cardiology Clinic of the “Prof. Dr. George I. M. Georgescu” Institute of Cardiovascular Diseases in Iași, Romania.

Results: The highest incidence of symptom onset was between 6:00 a.m. and 12:00 a.m., this morning polarization being more obvious in women. Within the first two hours of admission to the hospital, coronary angiography was performed in 78.1% of men and only 67.3% of women, the difference being statistically significant (p <0.05). We found that a large number of women had multivascular coronary disease (47.9% vs. 42.3%). At the same time, we found that left main disease and multivascular disease were more frequent in women than in men (3.8% vs. 0.7%, p = 0.001 for left main plus two-vessel disease, and 19.4% vs. 14.8%, p = 0.0005 for three-vessel disease).

Conclusions: In women, coronary events began more frequently in the morning, with atypical symptoms; also, fewer women presented to the hospital within the first 12 hours after the onset of the acute event. Compared to men, women from North East Romania present a higher incidence of multivascular atherosclerotic coronary lessions, indicating a higher severity of STEMI in the female population from this geographical area.
An Updated Review of Hypertensive Emergencies and Urgencies
Authors: Makó Katalin , Ureche Corina , Jeremiás Zsuzsanna 
Published: July 2018

Abstract
A hypertensive crisis is an abrupt and severe rise in the arterial blood pressure (BP) occurring either in patients with known essential or secondary hypertension, or it may develop spontaneously. The most frequent cause for the severe and sudden increase in BP is inadequate dosing or stopping antihypertensive treatment in hypertensive patients. Severe hypertension can be defined as either a hypertensive emergency or an urgency, depending on the existence of organ damage. In hypertensive urgencies, there are no signs of acute end-organ damage, and orally administered drugs might be sufficient. In hypertensive emergencies, signs of acute end-organ damage are present, and in these cases, quickly-acting parenteral drugs must be used. The prompt recognition, assessment, and treatment of hypertensive urgencies and emergencies can decrease target organ damage and mortality. In this review, the definitions and therapeutic recommendations in a hypertensive crisis are presented in the light of the 2017 ACC/AHA Hypertension Guidelines.
Changing Work Patterns of the Skolt Sámi
Authors: Itkonen Panu 
Published: July 2018

Abstract
This article explores changing work patterns in the Skolt Sámi reindeer herding community of Sevettijärvi, northern Finland. As a result of the Second World War, Finland lost the original home territory of the Skolt Sámi to the Soviet Union. The Skolt Sámi of the old Suenjel village moved to the Sevettijärvi area in Finland. In this article I present major changes in three areas of this group’s work patterns: 1) combinations of livelihood; 2) forms of cooperation and reciprocity; 3) social constructions of work situations. The main causes of cultural change in the rein-deer herding community have been the mechanisation of reindeer herding and the centralisation of reindeer ownership. In anthropological studies, traditional forms of behaviour have at times been seen as obstacles to economic development. My argument is different: traditional forms of culture – in this case forms of reciprocity – can increase possibilities for economic development. The research data shows that the centralisation of reindeer ownership has decreased the possibilities for economic development in additional forms of livelihood among Skolt Sámi reindeer herders. The number of herders has decreased and the entrepreneurial collaboration is arranged so that there is less and less traditional reciprocity between separate households.
Exchange interaction in itinerant-electron metamagnetism
Authors: Grado-Caffaro M. A. , Grado-Caffaro M. 
Published: July 2018

Abstract
The exchange interaction in itinerant-electron metamagnetism is investigated theoretically. In fact, by considering spin-up and spin-down electrons in an itinerant-electron metamagnetic gas in the presence of an external magnetic field, we show that the difference between the Fermi energies of the spin-up and spin-down electrons equals, up to a multiplicative constant, the absolute value of the matrix element of the Hamiltonian operator relative to the interaction in question. Furthermore, the Stoner formula for the electronic energy of the gas is used to study the size of the exchange interaction.
An Exploration for the Motives Behind Enhancing Senior Banker’s Level of Organizational Resilience: A Holistic Case Study
Authors: Mousa Mohamed , Sai Andrew Adjah , Salhin Gehad 
Published: July 2018

Abstract
Both the unpredictability of business environments and the limitless demands of stakeholders have fostered the emergence and spread of the concept of “organizational resilience” over the past two decades. This concept entails a quick recovery from unexpected shocks and an agile capacity to turn these shocks into opportunities. The concept has found a considerable space in many academic disciplines like child psychology, psychology and crisis management. However, it is still considered an emergent concept in organization- related studies. This study has focused on three branches of Cairo bank, which is the third biggest bank in Egypt, conducted interviews with 24 senior bankers of Cairo Bank, Egypt; and analyzed results of the interviews. The authors have created a model depicting the four main motives behind Cairo bank’s attempts to raise its senior bankers’ level of resilience. The four motives are: uncertainty, stakeholders’ pressure, bank culture adaptability and senior bankers’ voice.
