Each local, self-government unit which is planning to develop and later implement the project of landconsolidation is confronted with the problem of choosing the cadastral municipality for landmanagement via land consolidation. The appliance of multi-criteria decision method enables and helpsthe decision makers to act regularly and correctly when making a decision. Multi-criteria analysis,above all, enables decision making in conflict conditions. These conditions include multiple alternativesand criteria, from which some should be maximized, and others minimized. This paper deals with theproblematic of the ranking of cadastral municipalities in which land management should be performedwith the use of land consolidation, by applying COPRAS method. The paper also presents theevaluation of the defined model in the Municipality of Pećinci.

The major task of multi-purpose reservoir „Modrac“ operation is to decide how much water should bereleased now and how much should be retained for future use given some available and/or forecastedinformation at the beginning of the current time period. In practice, reservoir operators usually followrule curves, which stipulate the actions that should be taken conditioned on the current state of thesystem. Through construction of the dam Modrac in 1964, the reservoir of the same name was formed.Its primary objectives were the provision of technological water for industries in the Tuzla region andmitigation of downstream floods as well as recreation and other purposes. The multi-purpose reservoirModrac is currently a drinking water source for the municipality Tuzla. In order to better manage of themulti-purpose reservoir „Modrac“, certain analyzes are presented in this paper.This paper presents an analysis of annual precipitation, mean annual inflows in the catchment area ofthe multi-purpose reservoir „Modrac“ for the period 1967 - 2016. In this paper there are presentedstatistical datas on the maximum amount of precipitation for the dry season period (May to October) fordifferent return periods, for different distribution curves, as well as the maximum amount ofprecipitation for the wet season (November to April) for different return periods for different curvesdistribution.This paper provides information on the movement of precipitation changes in the catchment area ofmulti-purpose reservoir “Modrac” for the period from 1967. – 2016.

Levels of SO2 in air samples from urban zone of Banja Luka were determined at locality Center inBanja Luka (administrative center of the Republic of Srpska, in Bosnia and Herzegovina) which ishighly populated area, with intensive traffic and industry. Through experimental measuring, daily andweekend variation of SO2 concentration was determined. Daily variations are directly connected toregime and intensity of traffic and using fossil fuels. The paper presents measured average values ofsulfur dioxide, together with max and min values and relationship between some parameters of airquality and meteorological parameters, i. e. for pollution modelling together with meteorologicalparameters.

Noise pollution may have negative impacts on human health and environmental. The primary aim ofthis study is was to determine and mapping the noise pollution in the urban part of the city Banja Lukain Bulevar Cara Dušana by evaluating noise levels in the boulevards. The aim of this investigation isalso compare measured noise levels in the boulevards with legislation. The measured values exceededthe level of noise allowed. Because they are at all measuring points at study area mixing two zones I(hospital, rehabilitation) and III (trading, business, housing and housing next to traffic corridors,warehouses excluding heavy transport) it can be concluded that the noise level values in this area arealarming.

The map associated with this equation is always decreasing in the second variable and can be either increasing or decreasing in the first variable depending on the parametric space. In some cases, we prove that local asymptotic stability of the unique equilibrium point implies global asymptotic stability. Also, we show that considered equation exhibits the Naimark-Sacker bifurcation resulting in the existence of the locally stable periodic solution of unknown period.</jats:p>

The goals of this study were to identify groups of health-related behaviors among young adults (N = 314, Mage = 21.94, SD = 6.53), gauge the relation between emotional intelligence and health behaviors in this population, and assess health consciousness as mediator of said relation. Latent class analysis identified two mutually exclusive health behavior groups, which according to response patterns were labeled as Healthy and Unhealthy. The Healthy group (56%) was composed of individuals who had a healthy diet (i.e., low fat and high fiber), exercised regularly, and who frequently engaged in behaviors that prevent oral and skin-related diseases. In contrast, the Unhealthy group (44%) rarely engaged in these health-promoting behaviors. Using structural equation modeling we found a negative relation between emotional intelligence and unhealthy behaviors relative to health-promoting ones. Mediation analyses indicated that the mechanism explaining said relation was through increments in health consciousness, with large standardized indirect effects ranging between -0.52 and -0.78. As health behaviors during early adulthood are salient predictors of health outcomes in old age, the results have clear implications for the inclusion of emotional intelligence training in programs seeking to raise health awareness and cultivate health promoting behaviors in young adults, in so much as to seek to reduce the risk of chronic ailments later in life.

With the development of intense femtosecond laser sources it has become possible to study atomic and molecular processes on their own subfemtosecond time scale. Table-top setups are available that generate intense coherent radiation in the extreme ultraviolet and soft-X-ray regime which have various applications in strong-field physics and attoscience. More recently, the emphasis is moving from the generation of linearly polarized pulses using a linearly polarized driving field to the generation of more complicated elliptically polarized polychromatic ultrashort pulses. The transverse electromagnetic field oscillates in a plane perpendicular to its propagation direction. Therefore, the two dimensions of field polarization plane are available for manipulation and tailoring of these ultrashort pulses. We present a field that allows such a tailoring, the so-called bicircular field. This field is the superposition of two circularly polarized fields with different frequencies that rotate in the same plane in opposite directions. We present results for two processes in a bicircular field: High-order harmonic generation and above-threshold ionization. For a wide range of laser field intensities, we compare high-order harmonic spectra generated by bicircular fields with the spectra generated by a linearly polarized laser field. We also investigate a possibility of introducing spin into attoscience with spin-polarized electrons produced in high-order above-threshold ionization by a bicircular field.

A frequent complication during hospital stay of patients with urinary tract infections (UTIs) is a re-infection of the urinary tract after the initial improvement. In this study, we investigated the impact of two empirical antibiotic therapies on the outcomes of complicated bacterial UTIs. We retrospectively evaluated 325 adult patients hospitalized during 6 years period with a diagnosis of complicated bacterial UTIs. The patients were classified into two groups according to the antibiotic therapy: ceftriaxone- and co-amoxiclav+gentamicin-treated group. Clinical data were collected from the patient records into a designed form. Output data included information on the treatment outcome, length of stay (LOS), development of complications, and cause of re-infections. The patients treated with ceftriaxone had significantly longer LOS (p = 0.012), as well as higher occurrence of complications (p = 0.023) and urinary tract re-infections (p < 0.001), compared to co-amoxiclav+gentamicin-treated group. No significant difference was observed in the treatment outcome between the two groups (p = 0.137). The most common complication in both investigated groups were re-infections of the urinary tract, and Enterococcus spp. was detected as the cause of re-infections only in patients from ceftriaxone-treated group (40/69 patients). Out of the 40 ceftriaxone-treated patients with enterococcal urinary tract re-infections, 35 patients had one or more chronic diseases and 29 patients had urinary catheter inserted. Ceftriaxone therapy should be considered carefully in patients with complicated UTIs due to the possibility of enterococcal re-infection and consequent prolonged hospital stay.
