Livestock production is a potential environmental pollutan because of the high concentartions of animals on the small area. Production of biogas with anaerobic degradation from organic waste is one of the pledge alternative energetic solutions, especially from organic manure made from animal farming and other residuals of agricultural production.The aim of this paper was to determine posibillity of using manure different origin from extensive animal breeding for production of biogas in labaratory conditions. The results obtained will be based on posibillity of use waste streams from extensive animal husbandry as basic substrate for anaerobic digestion.In this regard, cosubstrates were formed as mixture 1 chicken excrement; mixture 2 sheep manure; mixture 3 cow manure; all three basic substrates were in mixture with the sludge from the wastewater treatment plant. The results showed production of 71,5 ml CH4/gVS for mixture 1, 68,65 ml CH4/gVS for mixture 2 and 48,68 ml CH4/gVS for mixture 3.

Bryophytes are a group of plants vital to many ecosystems and biogeochemical cycles and are well known bioindicators and biomonitoring tools. However, they have been deemed industrially less important than vascular plants and their potential for applications other than as biomonitoring tools has been overlooked. In recent years, however, bryophytes, and in particular mosses, are starting to gain attention as viable phytoremediation agents. Studies indicate that some moss species have the ability to uptake heavy metals such as Pb, Cd, Zn, Cu, As, and Cr from contaminated water. Tested mosses could both adsorb and absorb significant amounts of specific heavy metals without adverse effects on the plant. Results suggest that moss biomass, either dry or wet, could be used as a bio-sorbent in filtration of heavy metals. The review of available literature shows a promising prospect of moss to be used in phytofiltration of heavy metals. Existing knowledge on this topic could be the basis for further research which isneeded. KEYWORDS:moss; heavy metal; phytofiltration; bio-sorbent

Nowadays, bottled water has become part of the lifestyle, replacing tap water, and water from freestanding dispensers is increasingly being used. The main goal of this research was to determine the health suitability of bottled water in freestanding dispensers. The research included the microbiological analysis of a total of 100 samples of bottled water from freestanding dispensers. The samples were mostly taken in the wider area of the city of Doboj (doctor's offices, shops, public buildings), and one dispenser in the city of Tuzla. Water samples were taken twice, in the period from April to June 2022. Water samples from 6 different manufacturers (Vivia, Kristal, Nevra, Gora, Aqua doria, Aqua team) were analyzed. 9% of water samples (9/100) were microbiologically correct. Microbiologically defective samples contained a higher total number of bacteria at 22°C and 37°C, as well as a higher number of coliform bacteria than the maximum allowed values. No significant differences in microbiological quality were found between older and/or recently installed water dispensers, as well as in terms of environmental conditions, while visible differences were observed between dispensers that were regularly hygienically maintained.KEYWORDS:dispensers; bottled water; coliform bacteria; biofilms; total bacteria count

Public budgeting and finance is a discipline that encompasses communities of research and practice. Too often, however, these communities fail to engage each other, instead choosing to operate independently. The result is that the research being conducted fails to address the questions of the day and our governments’ challenges. In this article, we come together as a community of academics and practitioners to establish an agenda for where future research should be conducted. This agenda aims to align the research being undertaken within the academic community with the needs of those working in the community of practice. After establishing ten areas where research is needed, we followed a ranked-choice voting process to establish a prioritization for them. Based on the outcome of this process, the two primary areas where research is currently needed most are the fiscal health of our governments and the implementation of social equity budgeting.  

Simple Summary The aim of this study was to analyze and compare the morphology of root canals in the carnassial teeth of German shepherds and mixed-breed dogs. Knowledge of the morphology of root canals is essential for a successful endodontic procedure. It has been determined that an apical delta, which represents a complex structure that consists of multiple cavities whose purpose is to allow the passing of nerves and blood vessels from the pulp cavity to the apex of the root, was present in 247 roots. There are four main types of apical delta. The most common type in superior fourth premolars was type II, with up to 10 apical ramifications, whereas type IIIA, with 10–20 apical ramifications, was most commonly present in inferior first molars. Abstract Root canal treatment of carnassial teeth in dogs is a common endodontic technique which aims to re-establish or maintain the health of the periapical tissues. In total, 43 dogs were used in this study. Root canal morphology was evaluated in 86 superior fourth premolars and 86 inferior first molars. Apical delta was present in 247 roots, while obliteration of the root canal was found in 11 roots. The most common type of apical delta of the roots of superior fourth premolars was type II, with up to 10 apical ramifications, while type IIIA, with 10–20 apical ramifications, was most commonly present in the roots of inferior first molars. Considering that knowledge of the morphology of root canals is essential for a successful endodontic procedure, the aim of this study was to analyze and compare the morphology of root canals in the carnassial teeth of German shepherds and mixed-breed dogs. Apical resection for the purpose of endodontic therapy of the superior fourth premolar and the inferior first molar is indicated at a length of 4 to 6 mm from the anatomical tip of the roots, which would completely remove the apical delta of these two teeth.

– In this paper, the influence of waste shear strength parameters on landfill slope stability is studied. Namely, using the limit equilibrium method in GeoStudio 2018, stability analyses of a typical landfill slope are performed using semi-probabilistic and probabilistic approaches. The semi-probabilistic computations of slope stability are performed based on the available literature recommendations for the waste shear strength parameters. The results obtained for different recommendations are compared and discussed. In the probabilistic computations, the waste shear strength parameters are treated as random variables with Gaussian random distribution, where the parameters of the distribution are again selected based on the literature recommendations. Here, the influence of dispersion in the values of waste shear strength parameters is also examined. In addition, sensitivity analyses are also performed to gain insights into the relative importance of parameters. With the aforementioned analyses, an effort was made to investigate and derive conclusions about how the selection of waste shear strength parameters affects landfill slope stability.

BACKGROUND The aim of the study was to assess socio-demographical characteristics, clinical presentation, and outcomes in patients diagnosed with mpox. METHODS A survey on patients diagnosed with mpox was performed in 14 countries from Central and Eastern Europe. Data was compared according to HIV status and country of origin (EU vs. non-EU). Mpox diagnosis was confirmed by RT-PCR from oropharyngeal swabs, skin lesions, and other body fluids. RESULTS Out of 154 patients confirmed with mpox in 2022, 99.3% were males, with a median age (years) of 35 (IQR 30-39), 90.2% MSM and 48.7% PLWH.Compared to HIV-negative subjects, PLWH had more frequent high-risk behaviours:chemsex (p = 0.015), group sex (p = 0.027), and a history of sexually transmitted infections (STIs) (p = 0.004). Persons from EU were more often PLWH (p = 0.042), MSM (p < 0.0001), had multiple sexual partners (p = 0.025), practiced chemsex (p = 0.008) or group-sex (p = 0.005) and had more often history of STIs (p < 0.0001). The median CD4 cell count/mL at mpox diagnosis was 713 (IQR 486-996) and 73.5% had undetectable HIV VL. The commonest clinical features were fever (108 cases), lymphadenopathy (78), and vesiculo-pustular rash: penile (76), perianal (48), limbs (67). Fifty-one (31%) persons were hospitalized due to complications or epidemiological reasons. Three patients received tecovirimat or cidofovir. The outcome was favorable for all patients, including 4 with severe forms. CONCLUSIONS Mpox was diagnosed predominantly in young MSM, with high-risk behaviors and history of STIs. Effective contact tracing and vaccination are important strategic pillars to control mpox outbreaks.

Objectives. The purpose of this study was to determine whether fear and prejudice in relation to organ donation and the transplantation of organs may influence the decision to become an organ donor. Materials and Methods. Data were collected through four group interviews using open-ended questions and qualitative content analysis. Forty participants, 16 males and 24 females from seven countries, participated in the focus group interviews. Results. The analysis resulted in three main categories, and nine subcategories. Fears and prejudice caused by tradition and customs, approval of organ donation by family members, perception of the body as a gift from parents, the influence of religious leaders, knowledge about the religious understanding of organ donation, influence of social ambience on respondents, knowledge of the donation process in the healthcare system, including knowing about life after eventual organ donation, were some of predictors in the decision to agree to organ donation. Conclusion. More education on the factors that influence organ donation, more information in schools, health institutions and through the media, as well as more research with the aim of “dispelling” fears and prejudice about organ donation would significantly improve the current situation and result in a larger number of potential organ donors.
