The volumetric flow rate (injection velocity) and the holding pressure are metal injection molding (MIM) parameters that have a strong influence on the green parts density and density homogeneity, but their effect on sintered dimensions after sintering is still to a large extent unexplored. To reveal the relationship between the injection molding parameters and sintered dimensions, ring-shaped components were injection molded by using different values of injection velocities in combination with a rump-down and rumpup holding pressure profile. Afterwards, the green components were catalytically debound and sintered in the nitrogen (N2) atmosphere. Finally, the component dimensions: the height, inner and outer diameter were measured by using a coordinate measuring machine. The ready-to-mold granules Catamold 310N made of heat resistant stainless steel X40CrNiSi 25-20 (according to the EN standard) powder and polyacetal based binder were used. The results showed that the interaction between the injection velocity and the holding pressure profile can be used to systematically adjust shrinkage after sintering. This approach is based on the dependence of the binder crystallization temperature on pressure, when the powder/binder proportion changes with the injection velocity.

concept and and/or assembly of data; data analysis and interpretation; Research on moderate-intensity continuous training (MICT) is closely connected with primary and secondary cardiovascular protection but also can be associated with primary bypass patency and outcome of endovascular treatment for critical iliac stenosis TASC II A and B. After specific surgical or non-surgical treatment, iliac bypass or endovascular revascularization patency still depends on an individual and is still in the eye of scientific research modalities. Carotid intima-media thickness (CIMT) is an efficient surrogate parameter in detection and prediction of cerebrovascular events and potential marker of generalized atherosclerosis with prognosis of peripheral arterial disease related to prognosis of atherosclerotic coronary hemodynamic pathology. Materials and methods. A total of 139 patients were observed during 4 years of MICT. Ultrasonography of the distal part of the common carotid artery (CCA) was performed to measure CIMT before and after revascularization procedure. The bypass patency and walking distance was also studied. Results. In the total population, no difference in changes of CIMT from baseline was observed between the standard exercise group and controls in 4 years. However, there was a significant correlation between the effect of exercise training and CIMT within 4 years. CIMT was not significantly reduced in the exercise group compared with control non-diabetic patients. Conclusions. Exercise training in both groups did not significantly change carotid intima-media thickness in the four years following endovascular procedure and Dacron bypass revascularization, but significant beneficial effect of moderate-intensity continuous training on bypass patency was observed in patients with mild or without claudication symptoms as well as on subjective and objective health status.

Introduction: Aim of the study is to piloting nursing documentation to obtain comments based on the experience of nurses/medical technicians from the primary, secondary, and tertiary health care about the documentation before it is published and starts being used.Methods: A questionnaire was designed in the electronic form to be used for the evaluation and suggestions by nurses/medical technicians on the piloted form and content of nursing documentation for all levels of health care. A piloting sample was prepared to make 10% of nurses/medical technicians from health care institutions from the territory of the Federation of Bosnia and Herzegovina.Results: A total of 94.3% of examinees at the primary health care level and only 17.2% of the examinees in the secondary and tertiary health care fill out nursing documentation both manually and electronically. All examinees at all levels of health care understand the purpose and importance of nursing documentation. A total of 27.7% of the examinees at the primary and 40.9% of the examinees at the secondary and tertiary level of health care pointed out that filling out nursing documentation was too time-consuming.Conclusion: A total of 51.2% of the examinees at the primary and 64.2% at the secondary and tertiary level of health care agreed that submitted nursing documentation was adequate for use. It is suggested that after the adoption of nursing documentation at all levels of health care, piloting of its use should be conducted to evaluate the quality and quantity of all nursing documentation.

We present a realization of a didactic robot environment for robot PUMA 560 for educational and research purposes. Robot PUMA 560 is probably the mathematically best-described robot, and therefore it is frequently used for research and educational purposes. A developed control environment consists of a robot controller and teach pendant. The advantage of using a personally developed solution is its open structure, which allows various tests and measurements to be performed, and that is highly convenient for educational and research purposes. The motivation behind the design of this personal didactic robot control environment arose from a survey for students after the first Summer School on Mechatronic Systems. The student questionnaire revealed severe discrepancies between theory and practice in education. Even though the primary purpose of the new control environment for robot PUMA 560 was research, it was established that it is a viable lab resource that allows for the connection between theoretical and industrial robotics. It was used for the duration of four Summer Schools and university courses. Since then, it has been fully integrated into International Burch University’s Electrical and Electronics Engineering curriculum through several courses on the bachelor and master levels for multidisciplinary problem-based learning (PBL) projects.

Kajmak ist ein traditionelles Milchprodukt mit einer spezifischen Zusammensetzung und besonderen sensorischen Eigenschaften. Seine Herstellung erfolgt in ländlichen Haushalten und basiert auf einem traditionellen Verfahren. Die traditionelle Herstellung von Kajmak ist in Bezug auf die Art der Zubereitung sehr unterschiedlich, was zu großen Unterschieden in der Zusammensetzung, den Eigenschaften und der Qualität des Produkts führt. In der Verordnung über Milchprodukte und Starterkulturen ("Amtsblatt von Bosnien und Herzegowina", Nr. 21/11 und 17/19) in Abschnitt "H Kajmak" sind die grundlegenden Bestimmungen für Kajmak auf dem Markt von Bosnien und Herzegowina enthalten. Die Aufgabe dieser Arbeit besteht darin, den Unterschied zwischen industriellem Kajmak und Kajmak, der nach einer traditionellen Rezeptur und unter kontrollierten Produktionsbedingungen hergestellt wird, zu bestimmen und zu prüfen, ob die auf dem Markt befindlichen Produkte den gesetzlichen Vorschriften entsprechen. Die Proben für sensorische und chemische Analysen wurden aus den Regalen der Geschäfte in Bosnien und Herzegowina entnommen. Es wurden drei Sorten von industriellem Kajmak getestet sowie der unreife und reife Kajmak, der nach einem traditionellen Verfahren unter kontrollierten Bedingungen hergestellt wurde. Zweck dieser Untersuchung bestand darin, herauszufinden, was den Verbrauchern unter der Deklaration des Produktes angeboten wird, die sensorischen Eigenschaften des Produkts zu bewerten und das Produkt auf der Grundlage der erzielten Ergebnisse in eine bestimmte Gruppe abhängig von seiner Qualität einzuordnen. Nur eine der fünf untersuchten Proben entsprach den gesetzlichen Bestimmungen, die in Bosnien und Herzegowina in Kraft sind. Kajmak ist ein delikates Produkt, dessen Herstellung viel Aufmerksamkeit erfordert, und es stellt sich die Frage, ob die gesetzlichen Vorschriften zu streng sind oder ob die Hersteller der Art und Weise, wie dieses Produkt hergestellt wird, nicht viel Aufmerksamkeit schenken.

The kinetics of passive transport of ketoprofen and metformin, as model substances for high and low permeability, respectively, across the artificial membrane under the influence of the pH of donor solution was investigated. There was an upward trend in the apparent permeation coefficient (Papp) of ketoprofen with the decrease in pH to a value close to pKa. At the pH value below pKa the permeation coefficient had lower value, due to the higher retention of ketoprofen in the artificial membrane. Metformin is a low permeable compound, and the highest permeation values were recorded at pH 7.4. Two dissociation constants determine that metformin at physiological pH exists as a hydrophilic cationic molecule, i.e. predominantly in ionized form. At pH values below 2.8, metformin mainly exists in diprotonated form, and it was, thus, very poorly permeable. The highest retention, i.e. affinity of both ketoprofen and metformin to the membrane, was at the lowest pH values, which is explained by different mechanisms. At higher pH values of donor compartment the substances showed significantly less affinity to the membrane. The obtained values of apparent permeation coefficients at studied pH values showed good correlation with the obtained experimental values by other in vitro methods.

Castleman disease (CD) includes a group of rare and heterogeneous disorders with characteristic lymph node histopathological abnormalities. CD can occur in a single lymph node station, which is referred to as unicentric CD (UCD). CD can also involve multicentric lymphadenopathy and inflammatory symptoms (multicentric CD [MCD]). MCD includes human herpesvirus-8 (HHV-8)-associated MCD, POEMS-associated MCD, and HHV-8-/idiopathic MCD (iMCD). The first-ever diagnostic and treatment guidelines were recently developed for iMCD by an international expert consortium convened by the Castleman Disease Collaborative Network (CDCN). The focus of this report is to establish similar guidelines for the management of UCD. To this purpose, an international working group of 42 experts from 10 countries was convened to establish consensus recommendations based on review of treatment in published cases of UCD, the CDCN ACCELERATE registry, and expert opinion. Complete surgical resection is often curative and is therefore the preferred first-line therapy, if possible. The management of unresectable UCD is more challenging. Existing evidence supports that asymptomatic unresectable UCD may be observed. The anti-interleukin-6 monoclonal antibody siltuximab should be considered for unresectable UCD patients with an inflammatory syndrome. Unresectable UCD that is symptomatic as a result of compression of vital neighboring structures may be rendered amenable to resection by medical therapy (eg, rituximab, steroids), radiotherapy, or embolization. Further research is needed in UCD patients with persisting constitutional symptoms despite complete excision and normal laboratory markers. We hope that these guidelines will improve outcomes in UCD and help treating physicians decide the best therapeutic approach for their patients.

Abstract Bosnia and Herzegovina is located in the center of the Western Balkans. Until 2018 Bosnia and Herzegovina used the hazard maps based on the macroseismic intensity. The first generation of probabilistic seismic hazard maps of Bosnia and Herzegovina is compiled and presented. Two seismotectonic models were created, the areal and linear (fault) together with the earthquake catalogue filtered out from foreshock and aftershock events. Hazard maps were constructed in terms of the peak ground acceleration, and presented in two maps, with an exceedance on average once in 95 or 475 years. The hazard map used for the design of earthquake-resistant buildings (return period of 475 years with a probability of exceedance of 10% in 50 years) is created for the ground type A with the velocity of the seismic wave propagations of vs,30 = 800 m/s. These maps have been accepted as a part of the National Annex in BAS EN 1998–1:2018.

Introduction: Worldwide, COVID-19 pandemic caused millions of infected people and thousands of deaths. Due to enormous pressure on health-care systems and its inadequate preparedness, utter collapse is expected. In the current epidemic response, healthcare workers’ (HCWs) knowledge and practice are crucial, while the impact on their mental health is still unknown.Methods: The cross-sectional study was conducted among HCWs redeployed to COVID points in the Public Institution Health Centre of Sarajevo Canton. According to guidelines and information provided by the World Health Organization and Ministries of Health, a questionnaire was developed. In addition, General Anxiety Disorder-7 as a screening tool for anxiety disorders was used.Results: Of 180 respondents, 26 (14.4%) were in direct contact with the sick patient. In total, 79 (43.9%) respondents consider their personal protective equipment is in accordance with the guidelines of the world health authorities. A total of 72 (39.7%) of respondents used the same mask for several days. In general, the danger from new coronavirus was considered minimal by 59 (32,6%) HCWs. Based on the achieved score for assessing the anxiety disorder, in 63 (35%) subjects, the presence of severe symptoms was detected.Conclusion: This study found that most HCWs do not have enough knowledge about the COVID-19 pandemic. We identified that there are differences in the sources of information and gap in perceptions of the native origin of the virus. Considering the frequency of anxiety symptoms among HCWs, interventions are necessary in order to preserve their mental health.

Matrix factorization methods employ standard linear algebra, i.e. linear models, for recommender systems. With the introduction of the tropical semiring, we can achieve non-linearity. We review algorithms that use the tropical semiring for matrix factorization and provide their strengths and limitations. We show that the tropical matrix factorization yields better results than non-negative matrix factorization for the synthetic data created by the underlying process of the tropical semiring.

Introduction: Rhinoplasty is an esthetic and functional nasal reconstruction surgery. The elimination of physical disabilities directly affects mental health and leads to a better psychological balance. Therefore, patient satisfaction is considered a valuable measure of medical service outcomes. The objectives of this study were to evaluate subjective patient satisfaction 1 year after surgery and its influence on the quality of life.Methods: This was a clinical, retrospective, randomized, and single-blinded study in which patients were randomly questioned by the same examiner. All subjects underwent pre-operative preparation and post-operative flow at Eurofarm Centre from 2007 to 2010. The survey was conducted through anonymous questionnaires that were provided to each respondent at least 1 year after discharge from the hospital.Results: Overall, 20 (50%) patients had esthetic and 20 (50%) had functional nasal surgery. Most respondents were born between 1971 and 1980 (52.5%) and between 1981 and 1991 (40%), with the least born between 1951 and 1960 (2.5%). Regarding the education level, 27 had university degrees (67.5%), 1 had postgraduate education (2.5%), and 12 (30.0%) were secondary school graduates. In addition, 25 (62.5%) were unmarried and 15 (37.5%) were married.Conclusion: No statistically significant correlation was found between the subjective assessment of patient’s health based on eight dimensions of health assessment and variables such as type of surgery, age, level of education, and marital status 1 year after undergoing rhinoplasty. A statistically significant difference was found between the type of surgery and physical pain (p = 0.004 < 0.05, Mann–Whitney U test). Based on the research findings, we can conclude that patient satisfaction after undergoing rhinoplasty was moderately correlated positively with the quality of life (r = 0.180-0.345, p < 0.05).
