Various geophysical and physical processes, as well as the exploitation of objects, among other things, cause deformations of objects. The work of the geodetic expert is to detect the presence (absence) of deformation or deviations of the actual object from its planned geometry, with appropriate reliability measures. This paper presents the use of regression analysis as a verification process of two high-rise buildings (UNITIC towers in Sarajevo) verticality. Starting with the development of the geodetic network, through measurement and data processing, until the planning and execution of geodetic monitoring of buildings, as well as data processing, this paper is a well-rounded study. The entire process indicated that the regression analysis is extremely sensitive to measurement's accuracy, and the modeled directions that approximate building's edges tend to deviate from the vertical, which can be said in particular for the southern skyscraper (U2).

Galvanic coatings are applied so that the surface of the base material obtains appropriate properties, corrosion resistance, durability, aesthetic appearance, and long-term application in the appropriate industry. In this paper, the aim was to protect steel fuel filters with alkaline and acid zinc coatings of different thicknesses. The coating of zinc, which is applied from the alkaline electrolyte, provides good corrosion protection with excellent coating flexibility. The thickness of the coating by the X-ray fluorescence method was tested, followed by coating tests, corrosion resistance, and electrochemical tests. The results of adhesion showed a high quality coating, as no corrosion occurred during the test. The corrosion resistance tested by the salt chamber method speaks of the appearance of white and red corrosion. On alkaline electrolyte coatings, white corrosion occurred after 168 hours of exposure to the salt test, while on white zinc samples there was a white corrosion after 240 hours of exposure. Tafel polarization diagrams have been determined: corrosion potentials, current intensities, anode and cathode Tafel coefficients and calculated corrosion rates. The active and passive corrosion zone is determined by the cyclic voltammetry.

Introduction: Osgood-Schlatter’s syndrome (Osgood-Schlatter disease [OSD]) is caused by an accumulation of repeated microtraumas and is classified as a type of chronic injury called “overload syndrome“. It is considered that the root causes of OSD are accelerated growth as well as excessive sports and recreational activity. Currently, more than 50% of children of school age are involved in sports activities. In this study, 40 external risk factors were analyzed. Considering that frequent medical examinations, expensive rehabilitation, time-consuming sports activities, and school obligations result in major socio-economic and financial consequences, a need to work on a preventive program was recognized. The aim of this study was to determine external risk factors and to develop an algorithm for the prevention of injuries caused by overload syndrome through a detailed analysis of Osgood-Schlatter’s syndrome concerning aerobic and anaerobic sports (football, basketball, karate, and taekwondo). Methods: The research has been conducted on 200 patients who were previously diagnosed with Osgood-Schlatter’s syndrome. The participants were divided into two groups, each containing 100 patients, first group – aerobic sports (football and basketball) and the second group – anaerobic sports (karate and taekwondo). Personal information, anthropometric measurements, complete medical, and sports history were taken from the patients. A clinical examination was conducted by the researcher himself. This clinical study was prospective, comparative, analytical, and descriptive. The research was conducted in the Public Center for Sports Medicine of Canton Sarajevo. Software used for statistical data analysis was SPSS for Windows (version 20.0, SPSS Inc., Chicago, Illinois, USA) and Microsoft Excel (version 13 of Microsoft Corporation, Redmond, WA, USA). Results: Patients experienced the first symptoms of OSD at 4 years (football) and 6 years (taekwondo). About 60% of patients who trained in anaerobic sports and 38% of patients who trained in aerobic sports trained other sports more often as well. The research showed that a higher percentage of patients who trained anaerobic sports trained multiple sports at the same time (karate 88%, and taekwondo 82%) compared to patients who trained aerobic sports (football 68%, and basketball 76%). Patients who trained in anaerobic sports were also more likely to engage in recreational activities (58.3%) compared to patients who trained in aerobic sports (41.7%). On average, the number of hours per week which patients spent actively training (primary sport, additional sports activity, and recreational sport) was 17.2 h for basketball players, 16.8 h for taekwondo trainees, 16.7 h for caratists, and 15.7 h in case of football players. About 32% of football players, 24% of basketball players, 12% of karate trainees, and 18% of taekwondo trainees did not engage in additional sports or recreational activities. Only 36% of patients who trained in aerobic sports and 37% of patients who trained anaerobic sports respected the planned rest days, and in both groups, some subjects trained for 12 months. Conclusion: The research showed that patients who trained in anaerobic sports more frequently trained more than one sport at the same time and spent more hours doing recreational activities compared to patients who trained in aerobic sports. By analyzing weekly physical activity, it was concluded that the rest is limited. Future research aims to identify risk factors so that children, parents, and trainers can be educated to work on prevention through teamwork.

U radu je prikazana morfološka varijabilnost ploda 25 populacija javora klena (Acer campestre L.) na području Bosne i Hercegovine. Morfometrijsko istraživanje unutari među-populacijske varijabilnosti provedeno je na temelju 10 morfoloških značajki ploda, pri čemu su korištene deskriptivne i univarijatne statističke analize. Provedenim istraživanjem najmanje varijabilnim značajkama pokazale su se varijable koje opisuju oblik ploda, sa najmanjom varijabilnošću kod značajke odnos širine i dužine sjemenke. Za razliku od toga, za mjerene značajke ploda utvrđeni su viši koeficijenti varijacije. Najvarijabilnija značajka ploda u javora klena bila je dužina stapčice ploda. Najdivergentnije populacije obuhvaćene ovim istraživanjem bile su populacija Trebinje i populacija Rogatica. Za populaciju Trebinje utvrđene su minimalne srednje vrijednosti za pet od devet analiziranih značajki ploda, a za populaciju Rogatica maksimalne srednje vrijednosti za pet od devet analiziranih značajki. Analizom varijance ustanovljene su statistički značajne razlike između populacija za sve analizirane značajke. Isto tako, istraživanjem je utvrđeno da je unutarpopulacijska varijabilnost veća od međupopulacijske varijabilnosti za većinu istraživanih značajki. Odstupanje od tog pravila pokazuje varijabla F4 (dužina krilca ploda bez sjemenke) gdje komponenta varijance na međupopulacijskoj i unutarpopulacijskoj razini zauzima podjednak udio u ukupnoj varijanci. Provedena istraživanja morfološke varijabilnosti ploda javora klena u Bosni i Hercegovini predstavljaju pionirska istraživanja ove vrste, a dobiveni rezultati, temeljeni na morfometrijskoj analizi morfoloških značajki plodova, mogu poslužiti kao temelj za daljnja istraživanja.

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.

Abstract:Fingerspelling and its relationship with literacy skills among deaf and hard of hearing children who use American Sign Language is an increasingly popular research topic. However, there is limited research on whether reading interventions that systematically include fingerspelling are more effective for improving literacy skills than reading interventions that do not. In an adapted alternating-treatment single-case study, the authors contrasted the number of words learned under three conditions: a productive fingerspelling condition, in which word reading was taught through activities that emphasized productive fingerspelling; a chaining condition, in which teachers chained written words with receptive fingerspelling; and a sign-to-print condition, in which fingerspelling was not used. Five of the 6 participants learned most of the words taught with no differentiation by condition. Participants could recognize and fingerspell taught words, even if those words were not taught via fingerspelling.

Th is paper presents the results of chemical composition and microbiological safety testing of dry cured meat products, fermented and semi-dry or pasteurized sausages produced by several meat industries from Herzegovina. In the period from 2016 to 2018, a total of 85 meat products were sampled.Th ese included 20 samples of fermented pork sausages, 10 samples of dry-cured pork loin, 5 samples of dry-cured pork neck and 50 samples of heat-treated sausages. Quality control testing of the samples included determination of meat protein, crude fat, moisture, sodium nitrite and polyphosphates content in sausages, using standard analytical methods. It was confi rmed that all analysed samples meet the requirements in terms of chemical composition, level of additives and microbiological safety. In comparison with dry cured meat products and sausages analyses results, with minimum requirements that are set forth in regulations for that product category. Th e above mentioned suggests that the analysed samples are good quality products and they are in compliance with the regulations.
