Aim To assess the impact of the COVID-19 pandemic on admissions of patients with acute coronary syndromes (ACS) and primary percutaneous coronary intervention (PPCI) in countries participating in the Stent-Save a Life (SSL) global initiative. Methods and Results We conducted a multicenter observational survey to collect data on patient admissions for ACS, ST-elevation myocardial infarction (STEMI) and PPCI in participating SSL member countries through a period during the COVID-19 outbreak (March and April 2020) compared with the equivalent period in 2019. Of the 32 member countries of the SSL global initiative, 17 agreed to participate in the survey (three in Africa, five in Asia, six in Europe and three in Latin America). Overall reductions of 27.5% and 20.0% were observed in admissions for ACS and STEMI, respectively. The decrease in PPCI was 26.7%. This trend was observed in all except two countries. In these two, the pandemic peaked later than in the other countries. Conclusions This survey shows that the COVID-19 outbreak was associated with a significant reduction in hospital admissions for ACS and STEMI as well as a reduction in PPCI, which can be explained by both patient- and system-related factors.

Purpose: to determine the most significant kinematic indicators in the sports selection of beginner shot putters. Material and Methods: This study was carried out on a sample of 9 students at the fourth stage of the competition in Division 1, which took place in the 2017/2018 academic year at the Faculty of Physical Education of Maysan University. The following kinematic (biomechanical) parameters were analyzed: the angle of release of the nucleus, the velocity of release, the height of the point of ejection of the nucleus and the speed of swing. The correlation coefficients were determined between the kinematic indicators and the result in the shot put, as well as the regression equation for the dependence of the result in the shot put on the knematic indicators. The data obtained in the study were presented in the form of the arithmetic mean, standard deviation, median, skewness coefficient, Pearson's correlation coefficient, analysis of variance and linear regression, which included the contribution coefficients of each analyzed indicator, standard error, reliability of the regression equation as a whole, and reliability of the coefficients contribution to the shot put result of each kinematic exponent. Results. It has been shown that the swing speed has the greatest influence on the result in the shot put among beginner athletes. The swing speed, shot angle, shot speed and shot height have significant relationships with the shot put result. The multiple regression equation for the dependence of the shot put result on the swing speed, shot angle, shot height and shot point turned out to be reliable in general. However, only the swing speed has a reliable coefficient of the regression equation. The shot angle tends to be the determining factor in the shot put result. The release rate and the height of the release point have significant correlations with the shot put result, although in the regression equation they have unreliable indicators of influence on the shot put result. Conclusions. When teaching beginner shot putters, the greatest attention should be paid to the pushing swing technique, namely the swing speed. The second most important indicator is the angle of the shot put, it is recommended to use the basic prediction equation, which determines the expected results in the selection of young athletes in shot put, with high reliability of the results obtained. These characteristics are recommended to be used for evaluating young athletes, as well as in the process of training and preparing athletes for competitions.  

Purpose: The aim of the study was to determine the differences between football players and basketball players in the mean absolute values ​​of maximum torque flexors and extensors, ratio of maximum hamstring torque to maximum quadriceps torque dominant (DOM) non-dominant (ND) leg and differences in bilateral imbalance of flexor muscles and knee extensors. Material and methods: The research included a sample of 39 professional athletes. The first subsample included 19 professional basketball players while the second subsample included 20 professional soccer players. Results: Based on the results of the torques of the extensors in the knee joint of the DOM and ND legs, it was established that there is no statistically significant difference between basketball players and football players. However, a statistically significant difference was found in the torque flexors of the knee joint DOM (p≤0.01) and ND (p≤0.00) of the leg between basketball players and football players. On the other hand, the results of the research indicate that the difference between basketball players and football players in the ratio of Hamstrings peak torque to Quadriceps peak torque was recorded only in the ND leg (p≤0.02), while the difference in the DOM leg is not statistically significant. The results of our study indicate that basketball players have a higher percentage of imbalances compared to football players, especially in m. hamstrings. Conclusion: This study provides normative data on populations specific to soccer and basketball, but does not provide evidence of the ability of the isokinetic assessment of lower extremity muscle strength to predict injuries to football players and basketball players.

The aim of this study was to study the impact of crop load on the yield and grape quality of ‘Merlot’ and ‘Vranac’ (Vitis vinifera L.) in Trebinje vineyard. The crop load levels studied in this trial were 9 buds (V1) and 12 buds (V2) per vine at each variety trained on Lenz-Moser bilateral cordon system. The impact was determined by measurements of yield per vine and grape quality characterized by the contents of total soluble solids, titratable acidity, total phenolics, total flavonoids and by total antioxidant capacity. The measured parameters of grape quality of ‘Merlot’ and ‘Vranac’ were not influenced significantly by crop load levels. V2, compared to the V1, showed the potential for increasing grape yield only for Merlot variety under experimental conditions. The results of this study also showed a positive correlation between total phenolics/flavonoids and total antioxidant capacity of grape berries in both varieties, regardless of crop loads applied.

Rhetoric in Ancient Rome was a very specific type of discourse construction used to shape, present, and interpret specific works of individuals and then present them to critics. Depending on the perspective of the orator, defense counsel, or plaintiff, discourse strategies were aimed at legitimizing or delegitimizing a specific act. Words and wise acts of a skillful orator, which Cicero was renowned for, were often as powerful as weapons; they not only uncovered the intentions and objectives of participants in a given situation, but they reflected the social and political image of Rome, including the context of the event. The paper presents one of the possible methods of analyzing Cicero’s speeches made for the defense of Milo, a notable Roman charged for the murder of aristocrat Clodius Pulcher. It is based on the discourse-historical approach of R. Wodak and M. Reisigl. It is a qualitative analysis focused on the linguistic construction of the defense of the defendant at a trial. The analysis will show the discourse constructions produced under the influence of a set of specific social factors, in this case, the political environment in Rome, the ideological affiliation of speakers, and the main discussion participants – Milo and Pulcher, their political roles, and the degree of formality. The paper’s theoretical framework is a critical analysis of the discourse.

The paper analyzes the traces of Roman temples in the area of today’s Bosnia and Herzegovina. In the general, introductory part, the notion of the temple in the Roman world is dealt with. The sacred places of the native population, which were mostly under the open sky, were analyzed. According to the findings found so far, most of the Roman sanctuaries are dedicated to Jupiter and Liber. A number of sites were also recorded, which were probably temples, and for which it is not possible to determine to which deity they were dedicated. The remains of the temples have not been preserved, except for a few substructures, so the analysis was done on the basis of epigraphic material and context.

During one hundred years of the development of archaeology in southeast Europe, one of the dominant issues was the origin of communities that were recognized by former researchers as a homogenous component named the Illyrians. The issue of their origin was observed through different interpretations of wethnogenetic processes which numerous researchers tried to use to create different developmental phases of creating communities named after the Illyrians. By combining the most recent interpretations of concepts of myths and legends of the past communities, written data containing live memories of these myths during the past two centuries, as well as archaeological and historical data, the relationship and complexities of the oldest myths and legends, such as the one of Cadmus and Harmonia, are reimposed as they suggest the origin of the entire term of the Illyrians as a geographic and religious concept entirely dichotomous compared to, seemingly, misinterpretations of the wider ethnic context of the prehistoric Balkans.

Quantum Key Distribution (QKD) is an approach for establishing symmetrical binary keys between distant users in an information-theoretically secure way. In this paper we provide an overview of existing solutions that integrate QKD within the most popular architecture for establishing secure communications in modern IP (Internet Protocol) networks - IPsec (Internet Protocol security). The provided overview can be used to further design the integration of QKD within the IPsec architecture striving for a standardized solution.

Most pharmaceutical and nutritional compounds are marketed as enzyme inhibitors, and such inhibitors show their specific action in inhibiting enzymes within cells. Since their discovery, corticosteroid treatment has been one of the most used and effective treatments for various inflammatory and autoimmune disorders. Corticosteroids have anti-inflammatory and immunosuppressive effects, so it is hypothesized that these corticosteroids will have an inhibitory effect on the enzyme catalase. This study aimed to examine the effect of the corticosteroid’s betamethasone dipropionate and prednisone on catalase activity in vitro. A spectrophotometric method was used based on the reaction between hydrogen peroxide, enzymes, and corticosteroids. After incubation at 37°C with the addition of ammonium heptamolybdate, a stable complex was formed, and the absorbances were analysed. The obtained results indicate an uncompetitive type of inhibition in betamethasone dipropionate, while prednisone acts as a partial competitive agent.

This paper reviews a state-of-the-art zero emission propulsion system for a battery-powered small craft. The main aspects considered are the available propulsion systems, energy storage, and dock battery charging. This underlying activity is part of the KISS project, a research and development program in the frame of the EU-funded “Piano Operativo Regionale CALABRIA FESR-FSE 2014–2020 ASSE I–PROMOZIONEDELLA RICERCA E DELL’INNOVAZIONE”, which is aimed at designing and building a physical prototype. Its hull form is based on previous research conducted by the authors, and the powering performances were preliminarily predicted by CFD simulation. The KISS project represents a successful example of an electric small craft with performances and a mission profile comparable to competitors with conventional propulsion. Such a target has been achieved by a concurrent design that considers the hull form, engine, propulsion system, and energy storage onboard. Safety issues and the regulatory frame are also highlighted.

Chikungunya virus (CHIKV) is considered a public health problem due to its rapid spread and high morbidity. In 2016–2017 an outbreak of CHIKV was occurred in Pakistan but the data regarding the genomic diversity of CHIKV was not reported. Hence, the current study aimed to determine the genetic diversity of CHIKVs in Pakistan. A cross sectional study was carried out using sera of infected CHIKV patients (n = 1549) during the outbreak in Pakistan (2016–2018). Nucleotide sequencing of non-structural genes of CHIKV from eight isolates were performed followed by phylogenetic analysis using Bayesian method. Phylogenetic analysis suggested that the Pakistani CHIKV strains belonged to Indian Ocean Lineage (IOL) of genotype ECSA and C1.3a clade. Furthermore, the Pakistani isolates showed several key mutations (nsP2-H130Y, nsP2-E145D, nsP4-S55N and nsP4- R85G) corresponding to mutations reported in 2016 Indian strains of CHIKV. The molecular analysis revealed high evolutionary potential of CHIKV strains as well as better understanding of enhanced virulence and pathogenesis of this outbreak. The study highlights the need to continue surveillance in order to understand viral diversity over time and to devise preventive measures to limit diseases transmission in the region.

U Bosni i Hercegovini nedostaje istraživanja na području valorizacije georaznolikosti, što je rezultiralo zanemarivanjem njezinih znanstvenih vrijednosti, ali i nedovoljnim razvojem geoturizma. Cilj je ovoga rada valorizirati odabrane geomorfolokalitete Parka prirode Blidinje s obzirom na njihovu geoturističku vrijednost. Primijenjeni metodološki koncept nastao je kao rezultat analize postojećih metodoloških koncepata valorizacije georaznolikosti, pri čemu su objedinjeni kriteriji za procjenu osnovne, dodane, zaštitne i turističke vrijednosti. Jedan od ciljeva rada jest i doprinos boljem razumijevanju i primjeni metodoloških koncepata turističke valorizacije, posebice u okviru zaštićenih prirodnih područja. Tijekom istraživanja izdvojena su 44 lokaliteta, a na osnovi rezultata preliminarne procjene kreirana je lista s ukupno 23 lokaliteta koji su valorizirani, od čega se njih osam izdvaja većom ocjenom od prosječne. Rezultati ovoga istraživanja upućuju na potencijal za razvoj ponude geoturizma PP Blidinje, čiji bi temelj trebali biti najbolje ocijenjeni geomorfolokaliteti.

The analysis of data from the first two decades of the 21st century shows that the area under forests in Bosnia and Herzegovina is gradually decreasing. In order to gain a detailed insight into this process, the paper will analyse the forest databases of the European satellite monitoring program Copernicus. This program, among other things, monitors the condition of forests in 39 European countries by using the High Resolution Layer (HRL). The HRL Forests database consists of 3 types of (status) products, and additional change products. The status products are available for the reference years 2012, 2015, and 2018. The status layers provide information on the Dominant Leaf Type and the Tree Cover Density at pixel level for the reference year 2018 in 10 m resolution. The Forest Type layer largely follows the Food and Agriculture Organization (FAO) forest definition. Also, the paper will use the data on forests from the CORINE Land Cover project for 2000, 2006, 2012 and 2018. The time-series includes a land change layer, highlighting changes in land cover and land use. The CLC Changes database will be analysed separately for three periods: 2000-2006, 2006-2012 and 2012-2018, due to more accurate data on forest losses. The results of the research show that forests in Bosnia and Herzegovina were reduced by 2.95%, in the period 2012-2018, where 2.55% of them were coniferous. Forests are primarily endangered by the process of conversion to transitional forest / shrub and fires.

Genetic intra-tumour heterogeneity fuels clonal evolution, but our understanding of clinically relevant clonal dynamics remain limited. We investigated spatial and temporal features of clonal diversification in clear cell renal cell carcinoma through a combination of modelling and real tumour analysis. We observe that the mode of tumour growth, surface or volume, impacts the extent of subclonal diversification, enabling interpretation of clonal diversity in patient tumours. Specific patterns of proliferation and necrosis explain clonal expansion and emergence of parallel evolution and microdiversity in tumours. In silico time-course studies reveal the appearance of budding structures before detectable subclonal diversification. Intriguingly, we observe radiological evidence of budding structures in early-stage clear cell renal cell carcinoma, indicating that future clonal evolution may be predictable from imaging. Our findings offer a window into the temporal and spatial features of clinically relevant clonal evolution. A combined modelling and tumour analysis approach is used to study the temporal and spatial patterns of subclone evolution in the TRACERx renal study. Studying the tumour shape and spatial features of clonal diversity in early-stage tumours may allow the prediction of tumour progression and patterns of subclone diversification over time.
