The aim of our paper was to identify the effect of physical activities on the reduction of stress among the elderly who regularly participated in a physical activity program and point out the positive effects of these exercises. The research sample consisted of a total of 202 elderly people from 64 to 78 years of age. 102 of them regularly exercised within the framework of the Motion studio program...
A way to alleviate excessive Mn nutrition of plants is through silicon application. The aim of the present study was to examine the effect of different Si concentrations in a nutrient solution and Si plant spraying treatments (in the form of silica sol) on the yielding and nutritional status of hydroponically grown lettuce under Mn-stress. The experiments were conducted under controlled conditions...
Pulses are an important dietary constituent in human and animal diets. As well as being a source of income and livestock feed, pulses satisfy 33% of the dietary protein nitrogen (N) needs of humans. Pulses are often exposed to environmental stresses (biotic and abiotic) that decrease their productivity throughout the world. Abiotic stresses (drought, salt, temperature, UV, nutrient deficiency) alone...
Background: This research was aimed at describing the influence of selected intrapsychic factors related to “low” and “high” mountain conditions upon the efficiency of alpine skiing instruction. Material/Methods: Research participants were 48 people without skiing skills. Altitudes from 770 to 1,741 metres above sea level were chosen for “high” groups. A STAI questionnaire was chosen in order to carry...
Calculation of combined steel-concrete structures shall be conducted in stages. Before monolithic slab concrete gains strength, metal structure is the only structure part that carries loading of its own weight. However, after concrete gains strength, the whole calculated loading is carried by whole reinforced monolithic concrete slab where axis position changes. The article describes main principles...
The paper presented the results of studies of the stress-strain state at work steel cable block and channel Univ. Using finite element modeling performed numerical solution spatial and plane-hard contact problem using application software systems APM WIN Machine and Structure CAD. Analysis of static and dynamic load-nomic couples showed that ma-a maximal level of contact stress (stress field), and...
