Linear viscoelastic materials whose characteristics are suitable for description by the Prony series use experimental data to obtain the so-called “master” curve. The analysis of experimental results with the Prony model sometimes requires prior knowledge of the time parameters of the model ,, in order to make the corresponding module more suitable for use in analytical form. In this way, the existing model is optimized to some extent, while in this paper the approach is used that all parameters in the Prony series for (E i , τ i ) were determined using the well-known least squares method and its variations. The number of members in Prony’s series is initially smaller and increases proportionately. To determine the relaxation modulus using the Prony model, an example from an available article [1] was selected in this paper, while the performed experiment was used to determine the creep modulus. During the performance of the load experiment, the function of constant increase (ramp-test) was used. The previous experiment was done for the actual material ABS plastic (Acrylonitrile butaden styrene).

Introduction/Objective. The objective of this paper was to determine the connection between the socioeconomic status (SES) of the respondents and cigarette smoking and the use of alcohol and marijuana. Is there a connection between the SES respondents and their gender and place of residence? Methods. A total of 4188 primary and secondary school respondents from Brcko District of Bosna and Herzegovina participated in a cross-sectional study based on the European School Survey Project on Alcohol and Other Drugs questionnaire, adapted to this research. The data was collected using the questionnaire prepared for each respondent. Data on gender, marital status, occupation, and professional qualifications of parents were used to determine a family?s SES according to the Hollingshead methodology. Results. Alcohol and marijuana use are in relation to SES respondents (p < 0.001 or p = 0.008): respondents living in low-SES families use alcohol or marijuana at a lower percentage than respondents from middle-SES or high-SES families. Smoking habits are not in relation to SES respondents (p = 0.678). The place of residence is connected to SES respondents (p < 0.001): more respondents from low-SES families live in rural areas, while those from medium-SES and high-SES families predominantly live in urban areas. Conclusion. The SES of the respondents is in relation to their place of residence, alcohol and marijuana use, but it is not related to cigarette smoking.

Penile torsion is a rare congenital anomaly that is usually characterized by a counterclockwise rotation of the penile shaft or glans. Although several surgical techniques for its correction have been proposed, the consensus of choosing the most efficient technique remains controversial. Herein, we report our operational approach that successfully corrected a severe (>90 degrees) isolated penile torsion in the form of penile degloving and dorsal dartos flap rotation surgery.

Encapsulating peritoneal sclerosis (EPS) is a rare life-threatening complication associated with peritoneal dialysis (PD). EPS is characterized by progressive fibrosis and sclerosis of the peritoneum, with the formation of a membrane and tethering of loops of the small intestine resulting in intestinal obstruction. It is very rare in children. We present a case of a 16-year-old adolescent boy who developed EPS seven years after being placed on continuous ambulatory peritoneal dialysis (CAPD) complicated by several episodes of bacterial peritonitis. The diagnosis was based on clinical, radiological, intraoperative and histopathological findings. The patient was successfully treated with surgical enterolysis. During a 7-year follow-up, there have been no further episodes of small bowel obstruction documented. He still continues to be on regular hemodialysis and is awaiting a deceased donor kidney transplant. EPS is a long-term complication of peritoneal dialysis and is typically seen in adults. Rare cases may be seen in the pediatric population and require an appropriate surgical approach that is effective and lifesaving for these patients.

Dinamičan razvoj tehnologije materijala doveo je do primjene različitih novih materijala za poboljšanje svojstava nosivosti i trajnosti betonskih nosača. Jedan od pristupa jeste primjena sistema zaštite obložnog dijela betonskog nosača (zaštitni sloj betona). U ovu svrhu, razvijeni su polimerni materijali armirani karbonskim, staklenim ili aramidnim vlaknima (FRP – Fiber Reinfored Polymer). Novi pravac razvoja ovih sistema jeste primjena tekstilom armiranih sitnozrnih betona, gdje se koriste tekstili s vlaknima u više pravaca. Fabrički proizvedena ravninska tekstilna struktura sačinjena je od vlakana upletenih na razne načine, kao što su tkanje, pletenje, filcovanje ili štrikanje. Za potrebe istraživanja i razvoja ovog sistema ojačanja betonskih greda, formirana su dva istraživačka centra u kojima se sprovode projekti pod nazivom „Textile Reinforced Concrete (TRC) -Technical Basis for the Development of a New Technology” (SFB 532) RWTH Aachen University i „Textile Reinforcements for Structural Strengthening and Repair” (SFB 528) Technische Universitat Dresden. U ovim istraživačkim centrima sprovode se istraživanja mehanizama trajnosti, prionljivosti i kapaciteta nosivosti. Pored dva navedena velika projekta, postoji i niz projekata koji se odnose na tekstilom armirani beton, a sprovedeni su u Izraelu, Sjedinjenim Državama, Grčkoj, Belgiji, Ujedinjenom Kraljevstvu i Kanadi [3]. Utvrđeno je da količina i raspored tesktilne strukture imaju značajan uticaj na ponašanje tekstilom armiranog betona. Istraživanja su posvećena:

Abstract:The authors provide guidelines, based on an extensive review of the international literature, for conducting, interpreting, and reporting primary and secondary research on children who are deaf and hard of hearing in Bosnia and Herzegovina. The purpose of the review is to present arguments in support of conceptualizing education and rehabilitation, to explore the educational implications of such conceptualizations, and to suggest directions for future inquiry. Problematic areas are covered, such as research on the structure of a signed language, the use of information technology, inclusion, vocational and professional orientation, and motoric abilities and skills. The article concludes with recommendations for further investigating the educational achievement of students who are deaf and hard of hearing so as to improve educational practice.

The integration of remote sensing data involves combining various data to get better information, or more information about an area or phenomenon of interest. When it comes to combining data, it usually refers to multi-hour, multi-resolution or multi-sensor data linking. The subject of multi-sensor data integration is the combining of data collected by different sensors. A common example of this type of integration is the integration of multispectral optical data with radar imagery. Both spectrally different modes of representation complement each other: optical data is ''in charge'' of detailed spectral information (used to differentiate soil types) while radar data show structural details on the surface.

Global Navigation Satellite Systems (GNSS) are used for different purposes in geodesy, like engineering geodesy, land management, real estate cadastre, land surveying, etc. However, high-precision GNSS measurements are used primarly for determination of reference networks, and for investigation of geodynamical phenomena as tectonic plates movements, which is the focus of this paper. An active GNSS network of Bosnia and Herzegovina (BIHPOS) was used for calculation of coordinates and velocities of networks' stations. Data from 23 stations were processed using scientific software GAMIT/GLOBK (version 10.7), developed on MIT (Massachusetts Institute of Technology). A sub-centimeter accuracy of coordinates is achieved and accuracy of calculated velocities is better than 1 mm/year. Station velocities interpretate geodynamics of Bosnia and Herzegovina. Six IGS stations were used, as reference datum stations. Reference stations analysis results are in good match with EUREF Permanent GNSS Network velocities, while BIHPOS stations velocities (at 13 stations in Bosnia and Herzegovina) show very similar trend to the velocities obtained from regional geodynamic campaigns (CERGOP).

Background: Medicines dispensing is an error-prone activity, therefore potentially jeopardizing patient safety. This study aimed to assess the community pharmacists’ attitudes towards the causes of dispensing errors and preventive measures, as well as their practice in incidents reporting. Materials and Methods: A cross-sectional survey was performed by distributing an adopted and validated questionnaire to a nationwide sample of community pharmacists in Serbia. The questionnaire included sections related to the participants’ socio-demographic characteristics, their attitudes towards factors causing dispensing errors and corrective actions, as well as their practice in reporting. Statistical analyses were conducted using SPSS Statistics software ver. 21.0. The associations between categorical variables were analyzed using Chi-square test. Results: The study included 1,004 participants, mainly female (94.9%), with the mean age 40.9±9.9 years and mean work experience 14.3±10.0 years. More than a third of the participants (35.4%) indicated an increasing risk of dispensing errors. The main causes included illegible prescriber‘s handwriting (44.3%) and interruptions during dispensing (39.2%), while the major corrective actions were providing pharmacists with education in clinical pharmacy (71%) and reducing the interruptions during dispensing (63.9%). The majority of respondents (85.2%) stated that they routinely reported dispensing incidents. However, even 16.5% of them admitted to having fear sometimes or always. Additionally, only 58.1% of participants would use voluntary dispensing error reporting system. Conclusion: Serbian community pharmacists are aware of the existing risk in medicines dispensing and the corrective actions identified should be put into practice so as to manage them prospectively. Although the results indicate good practice in incidents reporting, conducting tailored educations and building of safety culture is necessary to improve patient safety.
