The industrial waste deposit in Žitkovac was utilized for the disposal of various metallurgical wastes, including lead refinery byproducts. This site has been contaminated for many years; despite the company maintaining records of waste disposals, weathering processes altered the waste, leading to the mixing of byproducts from lead production. Consequently, the mineralogical composition of the waste changed, and the behavior of toxic components was affected by weathering, oxidation, and penetration into the soil. To investigate this, eight characteristic samples were collected from three depths: the surface, 300 mm, and 500 mm. Specific sampling locations were chosen based on visible differences as well as the company’s records. The results indicated that lead, arsenic, and ferric compounds had penetrated the deeper layers of the soil, while copper, cadmium, and antimony remained primarily concentrated at the surface. It was noted that the gauge minerals, the agents used in refining residues, and the composition of the soil significantly influenced the behavior and penetration of pollutants within the soil column.

Effective removal of various pollutants from the environment has become one of the most important challenges of modern society. Carbon cryogels doped with nitrogen were synthesized and characterized using FTIR. All investigated materials have similar composition and structural disorder. The application of carbon cryogels doped with nitrogen for adsorption from tap water with the addition of OP pesticides gave successful results in stationary and dynamic conditions. Stationary conditions showed successful removal of aliphatic dimethoate and malathion for all tested materials, but they were less effective for aromatic chlorpyrifos. Under dynamic conditions, all materials effectively removed malathion and chlorpyrifos while showing suboptimal performance for dimethoate adsorption. The demonstrated efficiency indicates the potential application of these materials in water treatment. The toxicity of these pesticide solutions decreases over time, indicating that no more toxic products are formed.

This article addresses a sustainable approach to urban regeneration in post-communist residential neighbour-hoods in Sarajevo. The area explored is located in the municipality of Novo Sarajevo (literally, New Sarajevo), featuring well-known but somewhat controversial apartment buildings built after the Second World War, from the 1950s to the 1970s. At the time, this area epitomized the social and economic progress and expansion of the city from east to west, and it expressed the ideals of socialist modernist urban planning and architecture. More than seventy years later, following social, economic, and cultural transition after the war in the 1990s and new urban developments, this area and the city face multiple challenges, from decay to social bias. One key challenge is to adapt the residential architecture from socialist mod-ernism to meet contemporary requirements of functionality and sustainability. This research proposes the “new urban protocol” as a collaborative model combining tools and procedures for sustainable urban regeneration while focusing on reevaluating, retrofitting, and reprograming the architectural legacy of socialist modernism.

Cellular manufacturing represents one of the important segments in the application of the concept of Lean production, which is realized through the development and application of flexible manufacturing systems (FMS). FMS represent the basis for the production system to simultaneously achieve a high level of flexibility and productivity, that is, to be considered agile. However, due to their high production and technological capabilities, prices and investment costs, they require conditions that ensure their rational exploitation. Taking into account the increasingly complex conditions of production and placement of products, a systematic approach to the design and application of FMS is necessary, which will include the most important technological and economic characteristics. In this paper, on the example of the formed technological group of gears, the methodology of process planning and evaluation of the effects of cellular manufacturing is presented, as a basis for the rational development and techno-economic application of FMS.

Background: Thanks to advancements in neonatal medicine, perinatal morbidity has been significantly reduced, but the number of high-risk neonates continues to rise. Efforts to predict neurodevelopmental outcomes at an early age remain limited. The aim of this study was to analyze perinatal predictors of neurodevelopmental outcomes in high-risk neonates. Methods: A prospective, longitudinal two-year study was conducted at the Pediatric Clinic of the University Clinical Center in Tuzla. The study included 151 neonates, with 99 in the test group (with known perinatal risk factors) and 52 in the control group (without risk factors). Early neurodevelopment was assessed using the Alberta Infant Motor Scale (AIMS). Standard statistical methods were applied for data processing. The study was approved by the Institutional Ethics Committee. Results: Of the 151 neonates observed, 108 (71.5%) had normal neurodevelopment at 18 months, 29 (19.2%) had mild disorders, and 14 (9.3%) had developmental delays. In the group with suboptimal neurodevelopment, significantly more twin pregnancies, health problems during pregnancy, unnatural births, artificial fertilization, and pregnancy complications were recorded. In neonates, there were significantly more premature births, hypoxic-ischemic encephalopathy, and intracranial hemorrhages. Significant correlations were found between the mother's age and parity and delayed neurodevelopment. Additionally, correlations were found between birth weight, gestational age, Apgar score, length of hospitalization, and NICU stay with neurodevelopmental delay. Gestational age and the Apgar score at 1 minute showed significant negative predictive value for neurodevelopmental delay. Conclusion: Prematurity and perinatal asphyxia remain the greatest risks for adverse neurodevelopmental outcomes in neonates. These factors should be the focus of continued medical research and clinical practice. Neonates at the highest risk of developmental delay and their families should be prioritized for early identification, long-term follow-up, and timely interventions.

Acute mesenteric ischaemia (AMI) is a serious disease with mortality between 50 and 80 %. Oxidative stress plays a major role in the pathophysiology of AMI. AMI should be considered for any acute abdominal pain that requires analgesia with morphine and for which no other obvious aetiology is found. CT is the main diagnostic procedure to confirm the diagnosis of AMI. There is no specific diagnostic biomarker for AMI that can be used in routine practice. AMI is an urgent diagnostic and therapeutic situation. Treatment of AMI includes a protocol combining digestive rest, curative anticoagulant, antiplatelet, antibiotic therapy, arterial revascularisation to salvage viable bowel and resection of necrotic digestive segments. The strategy of revascularisation depends on the mechanism of arterial occlusion, the morphological appearance of the lesions and the indications for exploratory laparotomy. Endovascular and open surgical techniques can be combined and complemented. Open surgical revascularisation is indicated in case of failure or impossibility of endovascular revascularisation and in case of need for laparotomy. Early diagnosis and timely surgical intervention are the cornerstones of modern treatment to reduce the high mortality of AMI. The emergence of endovascular approaches and modern imaging techniques is developing and providing new treatment options. A multidisciplinary approach based on early diagnosis and treatment is necessary.

The development of agriculture is closely linked to technology and innovation. Drones have become a practical tool that helps improve agricultural production. This research focuses on choosing the spraying drone with the best features for the companyAgricultural goods Semberija. A multi-criteria decision-making process based on expert opinions was used to evaluate eight different drones across ten criteria. The fuzzy SiWeC (Simple Weight Calculation) method was applied to determine theimportance of each criterion, showing that all criteria were similarly important in the decision-making process. To select the best drone, the fuzzy COmpromise Ranking from Alternative SOlutions (CORASO) method was used. The results show that theDJI Agras T30 drone has the best features and is the preferred choice for purchase. These findings were confirmed by further comparative and sensitivity analyses. This study highlights the use of new methods for selecting equipment in agriculture.

The use of medicinal plants dates back to ancient civilizations, where they were the primary form of treatment. This interest has evolved with scientific advances and led to their modern use. Around 13000 medicinal plants are used worldwide, and 65-80% of the population uses them for therapeutic purposes. In Serbia, approximately 700 medicinal plant species are found, of which around 420 are actively used. An important medical field in which medicinal plants play a crucial therapeutic role is the treatment of urinary tract infections (UTIs). This study aimed to collect and document the diverse uses of medicinal plants and the traditional knowledge in Serbia regarding their therapeutic applications in treating UTIs.
