Waste is a by-product of human activities and living. With the increase in the number of inhabitants, the standard of living and urbanization, the quantities of municipal waste are increasing day by day. Every segment of waste management starting from generation, through collection, storage, transport, treatment and disposal can pose a potential hazard to human health and the environment. Waste management in Republic of Srpska is organized at the regional level. Since only waste disposal is still present in the Republic of Srpska, the regional approach implies that there is a landfill on the territory of one of the local self-government units, where all local self-government units in the region dispose of waste. In addition, waste disposal in illegal and unregulated landfills is still evident. LGUs or utility companies often face a lack of money to organize waste collection, with the result that not all households are covered by waste collection. In recent years, a lot has been invested in infrastructure, such as the filling of containers and containers and the purchase of new or newer used waste collection vehicles. Future directions of improving the waste management system in Republic of Srpska must go in the direction of sustainable waste management, ie waste management in a way to reduce the negative impact on human health and the environment, as well as avoiding leaving this problem to future generations.

Harmful effect of noise to the human health are various, begining from psihological to the irreversible damage of hearing. In order to prevent negative impact to the living and working environment, especially at the urban and industrial places where noise influence is the largest, at the specific location noise estimation must be performed before sources are build. Action of protection as well as reduction of the noise based on law and technical regulations, followed by detailed investigation are mostly applied in Banja Luka, the largest city of Republic of Srpska with huge dense of population and intensive traffic jam. Beside traffic noise, which has strongest effect to the human health, theoretical predictions are also performed for directional speakers, mostly temporary active in urban location during cultural manifestation. Theoretically obtained results from simulations are projected to the map of noise, where are further defined borders between places with enlarged noise in comparatione with referent levels, given by international standards but in agreement with national legislative. Review of data and their analysis in order to determine degree of the environment contamination in the Republic of Srpska with noise is the primary goal of this study. The measurement methods and theoretical assessment tools used for detection and prediction of these physical pollutants, which tend to grow permanently due to lifestyle, are also presented.

The problem of air pollution has been a challenge for modern humanity in recent times. The environment, including the air, is burdened by a large amount of pollutants that are released into the environment. The atmosphere contains primary and secondary pollutants, emitted as basic or specific pollutants. Air pollution is present in industrial areas and larger cities, with the fact that there are no areas without any impact of air pollution. Air pollution is also present in the Republic of Srpska, as is the case in other areas. Areas of increased pollution in Republic of Srpska, with high concentrations of pollution, can further worsen the impact on the population and lead to unwanted health effects.

The level of radio frequency radiation is followed by the growth of the new telecommunication technologies and the needs of the user. In order to prevent increasing of exposure over doses of electromagnetic radiation permitted for the general population, it requires to planing the construction of antenna systems and examine the living as well as working environment in their surroundings. City zones are potentially the most vulnerable on the exposure to high-frequency non-ionizing radiation, described below with examples of sensitive locations in Banja Luka such as the vicinity of schools, kindergartens and the hospital center. Review of data and their analysis in order to determine environment contamination level in the Republic of Srpska with non-ionizing electromagnetic radiation is the primary goal of this study. The measurement methods and theoretical assessment tools used for detection and prediction of these physical pollutants, which tend to grow permanently due to lifestyle, are also presented.

The Western Balkan region is known for emitting alarmingly high sulphur dioxide amounts from coal-fired power plants. Though a number of environmental regulations have been introduced in recent years (e.g. desulphurisation installations, construction of modern power plants), the pollution burden is still much higher than recommended by the authorities. A number of different montoring systems are required to observe the growing pollution situation in the Western Balkan region, partly caused by a high energy demand from outside (e.g. Western Europe).Several of the top ten SO2 polluters in Europe are located in Bosnia-Herzegovina and Serbia. Here we present the first in situ measurements of sulphur dioxide in this region conducted with a German research aircraft in cooperation with local scientists in Bosnia-Herzegovina and Serbia. Two of the strongtest emitting coalfired power plants were selected for the measurements in autumn 2020: Tuzla in Bosnia-Herzegovina and Nikola Tesla in Serbia (Nikola Tesla). The measurements were mainly conducted in the boundary layer (below ~1 km altitude in winter). Downwind of the power plants, extremely high SO2 mixing ratios exceeding 100 parts per billion (ppb = nmol mol-1 ) were measured at a distance of ~20-40 km from the sources. The SO2 plumes from the power plants were trapped in well-defined inversion layers between ~500-1000 m altitude. The airborne measurements can be used to validate synchronous spaceborne SO2 measurements from the TROPOspheric Monitoring Instrument (TROPOMI) onboard the Sentinel-5P satellite. A first intercomparison indicates some problems with dense smoke clouds frequently covering these countries in the winter months. However, it turned out that the Nikola Tesla flight is to some extent suited for a TROPOMI-SO2 validation, since it was obtained during cloud-free conditions with a well-defined vertical extension of the probed SO2 plume (needed to estimate the Vertical Column Density, VCD, measured by the satellite). In addition, these airborne measurements accompanied by model simulations can be used to determine the SO2 emission strength of the power plants and to compare it to the source strength reported by the power plant operators. The results indicate a reasonable agreement between the airborne measurements, model results, emission inventories, and satellite measurements for the Nikola Tesla power plants.

The concept of sustainable use of pesticides implies a series of rules, procedures and skills in the use of pesticides that are prescribed by the relevant legislation in the European Union, and which countries that are in the process of joining it are obliged to follow and apply. These prescribed norms include the development of a national action plan to achieve the sustainable use of pesticides; application of the principle of integral protection of plants; establishing a continuous training system for professional users of pesticides, distributors and advisors; establishment of appropriate conditions for the sale and distribution of pesticides; handling and storage of pesticides and disposal of their packaging and residues; regular control of pesticide application devices; keeping records and databases; informing the public and raising the level of awareness about the sustainable use of pesticides; application of measures to reduce the risk of pesticide use; the application of special practices in the use of pesticides, including aerial spraying, special measures for the protection of aquatic environments and drinking water, the application of pesticides on public and green areas, the reduction of pesticide use in certain areas, and the protection of bees during the application of pesticides, as well as the application of risk indicators, reporting and exchange of information on the sustainable use of pesticides. The purpose of this legislation is to achieve the sustainable use of pesticides and reduce the risks and negative effects from the use of pesticides in a way that ensures a high degree of protection of human and animal health, along with the protection and preservation of the environment and biodiversity, as well as the introduction of mandatory application of the basic principles of integral protection of plants for control of harmful organisms, including alternative approaches and techniques, such as non-chemical plant protection measures with the aim of achieving sustainable and competitive agriculture.

A broad range of ecological issues may be traced back to agricultural soil management methods that have a significant influence on ecosystems health across the globe. Agriculture has a major influence on the environment via soil quality deterioration or degradation. There are several types i.e., salinity, erosion, water logging and soil pollution with organic and inorganic contaminants and contributing factors to soil degradation. The inclusion of sustainable development goals (SDGs) related to the soil use as zero hunger (SDG 2), decent work and economic growth (SDG 8), climate action (SDG 13), life on land (SDG 15) contributes and important in human wellbeing via producing food crops (SDG 2), increasing economic growth (SDG 8), sequestering atmospheric emissions for climate change mitigation (SDG 13), and betterment of life on earth (SDG 13). Factors include non-suitable agricultural practices, usage of wide fields without limits to impede water flow, and improper ploughing techniques. The key element to limit the soil degradation is reducing pressure on natural resources and their over-exploitation. In this chapter, authors have discussed the soil degradation, causes and their remedies in detail.

Water is a unique and irreplaceable natural resource of limited quantities and uneven spatial and temporal distribution. All life forms and all human activities are more or less related to water, clearly showing the importance of the relationship with water. It is a necessary resource in households as drinking water, washing and food preparation, in agriculture for irrigation, and in industry it plays an important role in almost all industrial processes. Economic development and urbanization lead, on the one hand, to a large increase in water demand, and on the other hand to the threat to water resources and the aquatic environment. Water can thus become a limiting factor in development, a threat to human health and the sustainability of natural ecosystems. Until recently, there was a centuriesold illusion of water inexhaustibility, and the concept of minimum investments for the purification of used water and water protection in general appeared. Much of the water used is not purified before it is discharged into watercourses and thus pollutes the water mass and reduces the resources of drinking water. Providing enough drinking water is one of the world's most important issues today. Therefore, it is especially important for every society to balance these relations and devise policies and strategies for the regulation, exploitation and protection of water resources.

This research will look at the requirements that must be possessed by Qur'an commentators who have developed in every era. As a limitation, this research focuses on the affirmative era of interpretation (8-15 AD) and reformative era of interpretation (19 AD). The main sources of this research are four books written by commentators representing each era; two commentators from affirmative era of interpretation; Az-Zarkasyi and As-Suyuthi, and two commentators from reformative era of interpretation; Ahmad As-Syurbashi and Quraish Shihab. Using a socio-historical approach, this literature-based qualitative research concludes that there have been developments in the requirements of commentators in each era. From only to require mastering Ulumul Qur'an skills to demand of mastering a set of modern knowledge. All of this cannot be separated from the influence of historical facts on the problems and demands of the times faced by these commentators.

<p style="text-align: justify;">Gazelles represent fast-growing companies that significantly contribute to company growth and creation of new jobs. Different definitions of gazelles and criteria for their categorization are mentioned in the literature. The aim of this paper is to demonstrate that definitional differences and conceptual understanding of gazelles, as well as the criteria for classifying them, significantly affect the number of companies that can be categorized as "fast-growing". This paper analyses companies from Bosnia and Herzegovina and reveals significant deviations in the number and sector of companies that may be considered fast-growing. The deviations depend on the period of company observation (three-year vs. five-year period), as well as the applied criteria (income growth vs. increase in the number of employees). Likewise, the application of different definitions of growth, different criteria for measuring company growth, different indicators (relative vs. absolute) as well as different time frames significantly affect the interpretation of growth. The argument argues that such instances significantly affect the categorization and registration of companies that may or may not be considered fast-growing. Our research also confirms that workplace generators are precisely those firms whose expansive growth lasts beyond the initial three years but once they operate beyond four or more years, their power to generate jobs decreases significantly. The results of this analysis also indicate that in Bosnia and Herzegovina, fast-growing companies are, to a certain extent, new job generators.</p> <p style="text-align: justify;"><strong>JEL:</strong> M13, M21, L25</p>

Context: Evaluation of visual quality in soft and rigid gas-permeable contact lens wearers, with an emphasis on twilight vision. Purpose: To assess the visual acuity and visual performance at dusk before and after soft and rigid gas-permeable contact lens (CL) correction in healthy subjects. Settings and Design: This prospective study was conducted in a tertiary eye-care center. Methods: Sixty eyes corrected with soft contact lenses (SCLs) and 30 eyes with rigid gas-permeable contact lenses (RGPCLs) were enrolled in this study. Patients underwent corrected distance visual acuity with spectacles (CDVAs), corrected distance visual acuity with contact lenses (CDVAcl), and twilight vision (TV) testing (Vista Vision Far-Pola, DMD MedTech charts). Parameters were evaluated before and after the CL fitting and repeated 3 months after the baseline visit. Statistical Analysis Used: MedCalc for Windows, version 11.4 (MedCalc Software, Ostend, Belgium). Results: Rigid gas-permeable CL wear showed significant improvement in CDVAcl compared to wearing spectacles on both visits (P = 0.0039 and P = 0.0003, respectively). TV with CLs was significantly better in both groups compared to the TV with spectacles at the baseline visit (P = 0.0011 in SCL group; P = 0.0001 in RGPCL group), and at the follow-up visit, this significance was proven for the RGPCL group (P = 0.001). Also, spectacle TV showed a significant improvement on the follow-up visit (P = 0.0022 in SCL group; P = 0.0269 in RGPCL group). Conclusion: Contact lens wear improves visual performance compared to spectacles. TV results showed superiority of CLs compared to the spectacles, without a statistical difference regarding the CL type.

For many years, cargo traffic was marred by inefficiency, slow work systems, extensive paperwork and inaccuracies in the supply chain and transportation to the final destination. Processes within the chain itself entailed slow work, which resulted in large deviations in terms of transport and delivery time to the end user. To overcome these shortcomings and improve cargo traffic, the focus of the work will be on the application of innovative technologies in cargo traffic, the analysis of the application and the advantages it provides. A special aspect of the work is the analysis of cargo traffic in Bosnia and Herzegovina and the application of innovative technologies in its area.

Europski ariš (Larix decidua Mill.) pokazao je vrlo dobar rast i prilagodljivost ekološkim uvjetima u Bosni i Hercegovini. Cilj istraživanja je utvrditi varijabilnost morfoloških svojstava ariša na pokusnoj površini kod Kaknja, te varijabilnosti u početku osržavanja, kao i postojanje korelacija između ovih svojstava. U sjemenskoj sastojini ariša, osnovanoj sadnicama starosti 2+0 1979. godine, napravljena je trajna pokusna površina od 0,45 hektara i na njoj mjerene su visine i promjeri stabala 2002. i 2020. godine, te izračunate temeljnica i volumen. Stabla su 2020. godine bušena na prsnoj visini Preslerovim svrdlom kako bi se odredio udio osrženosti. Izračunate su prosječne vrijednosti svih svojstava. Zatim je odabrano po deset, pet i jedno najbolje stablo po svojstvima promjera, visine, temeljnice, volumena i izračunate razlike između prosječnih vrijednosti za deset stabala i ukupnog prosjeka, prosjeka za pet stabala i ukupnog prosjeka, te razlike između maksimalnih i prosječnih vrijednosti za istraživana svojstva. Također je izračunavat Pearsonov koeficijent korelacije između svih istraživanih svojstava. Prosječan promjer stabala starih 41 godinu bio je 24,6 cm, prosječna visina 21,8 m. Rezultati istraživanja osrženosti su pokazali da ariš prosječno počinje osržavati pri starosti od 14 godina. Pearsonov koeficijent korelacije za 2020. godinu pokazuje da postoji negativna korelacija između početka osržavanja prema svim ostalim svojstvima, odnosno stabla koja ranije osržavaju imaju veće vrijednosti svojstava rasta. Rezultati će biti korišteni u procesima individualne selekcije ariša sa dobrim visinskim i debljinskim prirastom i ranim osržavanjem.

Created in the 7th century, Uzrit love poetry or desert love poetry is inspired by love. It is named after the tribe to which poet Džemil (Ğamīl), one of the most famous love poets, belonged. In these poems, a lover spends his whole life in longing and absence, yearning for his beloved one. At the end of the 19th and the beginning of the 20th century, European romanticists sang and composed songs following, among others, Uzrit poets. Thus, Heinrich Heine sang the song Der Azra, writing down the Arab tradition of the Banu ʻUzra (Banū ʻUḏra) tribe that "for love lose their heads and die when they kiss". Hajne also influenced romanticists, such as Bašagić and Kostić. We can assume that Bašagić was directly influenced by the Arab love poetry of the desert because he knew the Arabic language, studied at university, and translated numerous poems from the Arabic language. However, when it comes to Kostić, the influence was indirect. A factor that should not be excluded from the research on the influence of Uzrit love, as a phenomenon, on romanticism, but also on the entire literature of the Balkan peoples, is folk poetry, which is filled with motifs from the East, and especially the Uzrit understanding of love. We witness the unavoidable influence of numerous folk songs, which later grew into songs sung with musical instruments, sevdalinkas, which the poets of the Balkans, regardless of national-confessional affiliation were exposed to. That folk lyric sang about exactly what Uzrit poetry sang about and it often drew its motifs from the Uzrit understanding of love. Keywords: comparative literature, Uzrit poetry, romanticism, Safvet-beg Bašagić, Laza Kostić
