INTRODUCTION Childhood obesity is currently considered to be one of the most prevailing and challenging public health issues in industrialized countries and some developing countries, including the Republic of Srpska. OBJECTIVE Our objective was to determine macronutrients intake in collective diet of preschool children and to estimate the rate of obesity in this population. METHODS Samples of food intended for preschool children diet were collected in a preschool facility in the western region of the Republic of Srpska. In daily portions, the content of proteins, fats, carbohydrates, water and mineral matter were determined using standard methods. The body mass index was determined on the basis of anthropometric measurements. RESULTS An average daily meal contained 17.5 g of fats, 19.1 g of proteins and 101.5 g of carbohydrates. The energy value was 676 Kcal. The analysis of the data from the menu showed that the number of consumed servings of fruits, vegetables, legumes, milk and dairy products was less than one portion per day. However, the amount of consumed meat and meat products exceeded one portion per day. Out of the total number of children, 10.0% were undernourished, 16.7% were overweight and 13.3% were obese. CONCLUSION Daily portions in the preschool facility are not in accordance with the recommended dietary allowance for energy and carbohydrates intake, and the composition of meals is inadequate. Parents and caregivers should be encouraged to expose young children to a wide variety of fruit and vegetables, whole grains, low-fat dairy products, and to balance food intake with the requirements.

Abstract An action have cities worldwide, due to urbanization. More than 70 percent of people in Europe live in cities, where 70 percent of the energy consumed. Without adequate measures, a rapidly growing city is at risk in by overloading the infrastructure, threats to water, energy, pollution, logistical bottlenecks and lack of housing. This paper describes an energy-efficient renovation or expansion planning a real estate in Vorarlberg, Austria. The settlement was analysed in more detail here, it involves the city Dornbirn- part Shor. The study investigated how to extend this settlement energy efficient and what feed for factors in the assessment.

Abstract We define modified Li coefficients, called τ-Li coefficients for a very broad class S ♯ ♭ ( σ 0 , σ 1 ) of L-functions that contains the Selberg class, the class of all automorphic L-functions and the Rankin–Selberg L-functions, as well as products of suitable shifts of those functions. We prove the generalized Li criterion for zero-free regions of functions belonging to the class S ♯ ♭ ( σ 0 , σ 1 ) , derive an arithmetic formula for the computation of τ-Li coefficients and conduct numerical investigation of τ-Li coefficients for a certain product of shifts of the Riemann zeta function.
