In order to achieve economic progress in less developed countries, it is necessary to provide the necessary resources. Foreign investments very often represent the primary source of financing for certain world economies, and the struggle for financial resources, which are limited, is becoming greater. Many countries have a planned approach to this process, and make huge efforts to attract foreign investors. For this reason, it is necessary to systematically approach this research problem, and to create adequate strategies for attracting foreign investments. When it comes to Bosnia and Herzegovina and the surrounding countries, the competition to attract foreign investments between them is getting tougher. Each of the neighboring countries has its own competitive advantages, and with an adequate set of incentive measures, it can achieve a significant inflow of foreign investments. Unfortunately, of all the surrounding countries, Bosnia and Herzegovina has the lowest inflow of foreign investments, so it is necessary to define the competitive advantages of the business environment in Bosnia and Herzegovina.

RESUMO Objetivo: Analisar os fatores maternos e neonatais de recém-nascidos de mães adolescentes associados à reinternação hospitalar no período neonatal. Método: Estudo quantitativo transversal, retrospectivo e analítico, com 489 recém-nascidos de mães adolescentes, nascidos em 2019 e 2020 em um hospital público de alta complexidade, localizado na região Sul do Brasil. Os dados foram coletados por meio de uma query e analisados no software SPSS utilizando os testes qui-quadrado ou exato de Fisher. Para controle de fatores confundidores, empregou-se o modelo multivariado de Regressão de Poisson. Resultados: A prevalência de reinternação hospitalar de recém-nascidos de mães adolescentes foi de 9,2%, principalmente por condições respiratórias, sendo o diagnóstico de bronquiolite aguda o mais prevalente, com 22,3%. Conclusão: A reinternação hospitalar neonatal esteve associada à prematuridade, ao Apgar 1º minuto <7 e à procedência da mãe.

Ovaj rad prikazuje tematiziranje ustaškog i četničkog pokreta u časopisu “Bosanski pogledi” u periodu od 1960. do 1967. godine. Časopis, čiji je glavni urednik bio Adil Zulfikarpašić, pruža značajan izvor informacija za proučavanje historijskih, socioloških i političkih aspekata. Kroz analizu različitih članaka autori istražuju percepciju i kritiku ustaškog i četničkog pokreta u Bosni i Hercegovini. Rad se fokusira na različite aspekte, uključujući ulogu Muslimana i njihovu saradnju s različitim pokretima, sukobe s drugim narodima i političke sukobe koji su prikazani unutar časopisa. Prikazuju se različiti stavovi i argumenti koje časopis donosi o ovim pokretima, ističući njihovu ulogu u Drugom svjetskom ratu i posljedice njihovih akcija. Kroz ovu analizu rad nastoji osvijetliti složenost i kontroverze povezane s temom, doprinoseći boljem razumijevanju balkanske historije i savremenih političkih odnosa.

This paper, based on the documentation from the database of the International Criminal Tribunal for the former Yugoslavia (ICTY), is dedicated to the suffering of the "Banja Luka babies", one of the many cases of tragic childhood during the aggression against Bosnia and Herzegovina in 1992. The case of the agony of new-borns in the Banja Luka Clinical-Medical Centre (CMC) caused controversy in the public. It is the subject of propaganda speculations and various political calculations that do not stop even with the act of presenting the medical documentation of the deceased newborns as exhibits for the defence during the trial of Radoslav Brđanin before the ICTY. Brđanin was found guilty and at the end of the trial sentenced to 30 years in prison for crimes against humanity, violations of laws and customs of war, and serious violations of the 1949 Geneva Conventions.

We investigate how the inverse degree index of graphs depends on their cyclomatic number. In particular, we provide sharp lower bounds on the inverse degree index over all graphs on a given number of vertices with a given cyclomatic number. We also deduce some structural properties of extremal graphs. Some open questions regarding the upper bound over the same class of graphs are discussed and some possible further developments are indicated.

In dieser Arbeit wird eine Strategie zur Bewertung des Zuverlässigkeitsniveaus von gemauerten Gründerzeithäusern im Erdbebenlastfall vorgestellt. Die Nachbemessungsstrategie ermöglicht eine normgerechte Bewertung der Schubtragfähigkeit, des Erdbebenerfüllungsfaktors sowie des personenbezogenen Risikos einzelner Schubwände (aussteifende Zwischenwände) in Form von Nachbemessungstafeln. Die Nachbemessungstafeln ergeben sich im Wesentlichen durch die einschlägigen Normen, der aktuell angewandten Pushover-Berechnungsmethode im gemauerten Altbestand, der gründerzeitlichen Bauwerkscharakteristika und der Standortgegebenheiten im Raum Wien. Die methodische Herangehensweise umfasste eine ausführliche Bestandsanalyse von mehr als 200 Gründerzeithäuser, die Nachweisführung der betrachteten Bestandsobjekte im Erdbebenlastfall, eine Sensitivitätsanalyse der Einflussparameter auf das sich einstellende Sicherheitsniveau und die Ableitung sowie Vorstellung der Nachbemessungstafeln. Die Mauerwerksqualität konnte anhand von umfangreichen Mauerwerksuntersuchungen von 125 gründerzeitlichen Objekten in der vorgestellten Strategie berücksichtigt werden.

The study of aerosol dispersion in indoor environments is essential to understanding and mitigating airborne virus transmission, such as SARS-CoV-2. Computational Fluid Dynamics (CFD) has emerged as a valuable tool for investigating aerosol dispersion, providing an alternative to costly experimental methods. In this study, we investigated the performance of four (4) Reynolds-averaged Navier-Stokes (RANS) turbulence models in predicting aerosol dispersion from a human body coughing in a small, ventilated indoor environment. We compared the Standard, RNG, Realizable k-ϵ models and the SST k- ω model using the same boundary conditions. We initially observed that the horizontal distance of the coughed aerosols after 10.2s dispersion time was substantially shorter with the standard k-ϵ turbulence compared to the other three turbulence models compared to the SST k-ω model, the RNG, and realizable k-ϵ models exhibit a high degree of similarity in their dispersion patterns. Specifically, we observed that the aerosols dispersed horizontally faster with the RNG and Realizable k-ϵ models. In conclusion, when compared to qualitative data from the literature, our observations exclude the standard k-ϵ turbulence. However, to select the most appropriate turbulence model for capturing the cough flow and aerosol dispersion dynamics, further detailed validation against both quantitative and qualitative data is needed.

The paper considers the possibility of improving the technical characteristics of gas surge arresters for the co-ordination of insulation at low voltage, medium voltage and high voltage levels. The idea for improving the characteristics of a gas surge arrester is based on the application of the radioactive source 241Am in the area of the surge arrester cathode. Intensive ionization with alpha particles significantly increases the number of free electrons in the space between electrodes, which shortens the time of their transition to initial electrons. This changes the Paschen curve of the gas surge arrester, narrows and flattens its impulse characteristic and reduces the stochasticity of the response of the gas surge arrester. All this results in a significant improvement in the characteristics of the gas surge arrester at all voltage levels. This improvement is particularly noticeable in the case of low voltage surge arresters. The paper is basically theoretical-experimental research. The experiments were performed under well-controlled laboratory conditions. The combined measurement uncertainty of all measurements was acceptable.

The acoustic adaptation hypothesis (AAH) is often tested between species from open and closed habitats. However, the acoustic differences are rather small and thus the evidence is ambiguous. We tested the AAH between subterranean and surface-dwelling species living in very different acoustic environments. Lower frequencies (<1 kHz) are transmitted best in subterranean burrows and there is a high-frequency cut off around 3 kHz. The other important factor influencing the frequencies of vocal signals is body size. Acoustic allometry – a negative relationship between body size and frequency of acoustic signals – indicates that larger species tend to produce sounds of lower frequencies than smaller species, due to their larger vocal apparatus. The present study shows, that acoustic allometry applies to subterranean as well as surface-dwelling rodents and that the environment influences the main frequency of their vocalization. Besides, the subterranean species tend to have lower vocal signals than surface-dwelling species.
