Description:
This article deal with phase diagnostics of femtosecond laser pulses and with its change to increase a nonlinear optical signal. We introduce a single shot technique of complex diagnostics SPIDER, which works on the base of interference in spectral region. Phase characteristics of investigated fs pulses incoming from oscillator was controlled by a prism pair. There was shown that phase characteristics changes of fs pulses leads to intensity changes of two photon fluorescence of coumarine C522 in ethanol.

Description:
The contribution refers on the accelerating of the process method of stress analysis using PhotoStressσ software applications PhotoStress. PhotoStress application was developed for the analysis of the direction and size of the main strain respectively the analysis of the main normal stresses on the loaded photoelastic coated structural elements on the authors workplace. It accelerates the process of measurement and evaluation of major strains and principal stresses at a point on the line or a curve respectively. It allows in these entities determining the direction and size differences and separated values of major strain or the stresses on the basic of the photo of loaded photoelastic coated objects. In the paper is describing the application PhotoStress and the view of the separation of the main normal stresses at using the method of oblique incidence photoelastic coated steel ring and also a comparison of results obtained PhotoStress software application and numerical solution, by the finite element method. and Príspevok poukazuje na urýchlenie procesu analýzy napätosti metódou PhotoStress® pri využití softvérovej aplikácie PhotoStress. Aplikácia PhotoStress bola vyvinutá pre analýzu smerov a veľkosti hlavných pomerných deformácií, resp. hlavných normálových napätí na zaťažených fotoelasticky povrstvených konštrukčných prvkoch na pracovisku autorov. Urýchľuje proces merania a vyhodnotenia hlavných deformácií, resp. hlavných napätí v bode, po úsečke, prípadne po krivke. V týchto entitách umožňuje určenie smerov a veľkosti rozdielov a separovaných hodnôt hlavných deformácií, resp. napätí na základe fotografie zaťažených fotoelasticky povrstvených objektov. V príspevku je uvedený popis aplikácie PhotoStress s ukážkou separácie hlavných normálových napätí pri využití metódy šikmého osvetlenia na fotoelasticky povrstvenom oceľovom prstenci a tiež komparácia výsledkov získaných softvérovou aplikáciou PhotoStress a numerickým riešením, metódou MKP.

6. Proteolytic enzymes secreted by larval stage of the parasitic nematode Trichinella spiralis

antibody inhibition, Trichinella spiralis, serine proteinases, larval stage, and excreted/secreted products
Language:

Description:
Excretory/secretory products (ES), collected from in vitro cultures of muscle larvae (l-l) of Trichinella spiralis (Owen, 1835) were examined for the presence of proteolytic enzymes. Several discrete proteinases in the size range of 25-55 kDa were identified by substrate gel electrophoresis and were characterised according to pH optima, substrate specificity and inhibitor sensitivity using azocasein assay. Serine, cystcinc and metalloproleinases active at pi I 5-7 were identified. The serine proteinases were found to predominate and some of them were found to be specific for the larval stage of the parasite. The results from the substrate analysis indicated the presence of collagenolytic and elastolytic activities. The proteinase activity was inhibited by IgG isolated from T. s/nrato-infcctcd mice, an observation of relevance to understanding host/parasite interactions and, ultimately, the development of anti-Trichinella vaccine.
