Influence of extra training means on effectiveness of fencers’ technical tactic actions

Purpose: to determine influence of the worked out extra training means’ complex on effectiveness of realization of elite sportsmen’s competition functioning components. Material: in the research 12 fencers participated. The researches were conducted in the morning, against the background of organism’s recreation. Before sportsmen’s duel we applied two types of pre-competition warming up: traditional and experimental. Video recording was fulfilled with video camera Samsung HMX-S15. Results: we calculated volume, effectiveness and efficiency of sportsmen’s actions in fights with different opponents and in different situations of duel. We showed possibility of extra training complexes’ application, oriented on mobilization of workability in the process of direct pre-start preparation of elite sportsmen. Such exercises considered main actions and organism’s typical responses in the process of competition functioning. Conclusions: Consideration of typolical (for fencing) organism’s responses and peculiarities of competition functioning structure influence positively on indicators of sportsmen’s competition functioning.

GMOs: The new hotspot in ecological research

Gene flow is an important ecological and genetic process, and the fitness conferred by the insertion of a foreign gene could be important in ecology after it becomes introgressed into the wild genetic background of organisms, which is the determinative factor for the fate of GMOs or foreign genes in natural ecosystem and for the competition with native species. Trophic interrelation fulfilled by food chains is the most important correlation between species in ecosystem and could be affected by the modified genotypes after the introduction of GMOs. The technology enabling the precise manipulation of genotype is a great opportunity for the study of ecological genetics in an unknown way prior to the biotechnology era. Especially interesting is the impact of genes on ecosystem function when GMOs are released into environment. A variety of ecological terminology has been frequently used in assessment of ecological risks related to the release of GMOs in environment, e.g. gene flow, fitness, interspecific competition and food chain. The value of GMOs in ecological research is illustrated through several examples in biosafety assessment related to those terms here. It is proposed that ecologists should pay attention to the study of gene function in ecosystem and take the opportunity to enrich ecological theory with the release of GMOs.

Flow Microcalorimetric Studies of Yeast Growth: Fundamental Aspects

The importance of factors such as cultural conditions e.g. organism background, inoculum density and glucose concentration are explored and their effects on the experimental recording discussed. The relevance of these findings to microbial microcalorimetry in general and to microcalorimetric identification of organisms in particular is described. The conclusions drawn are (i) that microbial identification by microcalorimetry is not possible and (ii) that great caution must be exercised in interpreting metabolic data derived from microcalorimetric studies.
