Climatic and anthropogenic impacts on forest fires in conditions of extreme fire danger on sandy soils

Forests on sandy soils are particularly vulnerable to fire. The study area in this research was Deliblatska pescara (the Deliblato Sands), one of the most endangered areas in Serbia. The linear trends, the polynomial trends and the Pearson correlation coefficient (r) were applied. Statistically significant decrease in the number of forest fires was found, while the increasing trends of the burned area and burned forest area were not significant. There was also an increase in the...

Model of Dependence Between the Parameters of Surface Roughness and the Parameters of Form and Location During the Machining by Drills with the use of Artificial Neural Networks

Abstract This paper presents a model of dependence between the parameters of surface roughness and the parameters of cylindricity and eccentricity in drilling operation for the enhancing steel EN 42CrMo4, hardness 28 HRC, with twist drills DIN 338 made of high-speed steel EN HS6-5-2, with normal blade. By the developing models based on artificial neural networks and using experimental results, it is possible to analyse the quality of machining on the basis of parameters of a surface roughness.

Assessment of stimulus distance during driving

We make about 1,400 decisions in one hour of the day, which makes about 35,000 decisions in 24 hours. The driver's task in traffic is to assess traffic situations and act in accordance with their decisions in traffic. One of the most common causes of traffic accidents is "misjudgment of road users". The perception of space is one of the prerequisites for safe and successful driving. In order to investigate the mentioned issue, the authors of this paper conducted an experimental study with the aim...

Emergency conversion of sports halls into temporary hospitals caused by COVID-19 pandemic: Case studies of thermal comfort and energy consumption analysis

An emergency caused by the COVID-19 pandemic affected the rethinking of existing healthcare systems. The increased need for hospital beds appeared short after the outbreak of the pandemic and the solution was to adapt the existing buildings, primarily public ones. Among all, sports buildings, i.e. sports halls were successfully used around the globe for conversion into hospitals. Topic of the paper was to investigate whether sports halls in Serbia, which were also used as temporary hospitals, are...

Antimicrobial veterinary drug sale pattern in correlation with critically important antimicrobials for human use: A five-year study in Montenegro

AbstractAntimicrobial resistance (AMR) poses a significant threat in veterinary medicine due to the excessive and inappropriate use of antimicrobial agents, compromising the effectiveness of these drugs. To combat AMR, the collection of data on the consumption of antibiotics is paramount, as there is a well-established connection between antibiotic use and AMR in both humans and food-producing animals. Hence, the current study aimed to generate measurable data concerning the sales patterns of antimicrobial...

Decomposition and Uncoupling of Multi-Degree-of-Freedom Gyroscopic Conservative Systems

Abstract This paper explores the decomposition of linear, multi-degree-of-freedom, conservative gyroscopic dynamical systems into uncoupled subsystems through the use of real congruences. Two conditions, both of which are necessary and sufficient, are provided for the existence of a real linear coordinate transformation that uncouples the dynamical system into independent canonical subsystems, each subsystem having no more than two-degrees-of-freedom. New insights and conceptual simplifications...

A Platform of Critical Barriers to Socially Sustainable Residential Buildings: Experts’ Perspective

The concept of sustainable cities and communities is endorsed as one of the seventeen goals of sustainable development. Since buildings represent an essential element of the city, they play a primary role in achieving the social, economic, and environmental sustainability of cities. Previous studies have pointed to the lack of emphasis on the social aspect of buildings. Aiming to fill the gap, this research is focused on identifying barriers that hinder the adoption of social sustainability (SS)...

Spatial and temporal variations of aridity indices in Montenegro

Abstract In this article, we examine the spatial pattern and trend in aridity in Montenegro from 1961 until 2020. We use temperature and precipitation observational records from 18 weather stations to calculate three aridity (climate) indices: the De Martonne aridity index (IDM), the Lang’s rain factor (RF), and the Pinna combinative index (IP). On an annual scale, all of these three indices show humid to extreme humid atmospheric conditions in Montenegro. At the seasonal and monthly level,...
