Systems with extreme bandwidth are part of advanced modern systems at radio high capacitive communication. Originally this technology was intended for radar scan. Thanks to wide frequency band had radar possibility „ see" a behind crimp, e.g. behind woody partitions etc . To his noise immunity, fail safe tapping plus small wattage heftiness began use for datal systŽm function. If is elementary antenna compound from coaxial probe and shorting outlet, it is possible use to actuating separate narrow slot placed in the middle of incandescent dabs. Impedance and radiating characteristics conventionally plumbed phlobaphene antennae excited tape lead and suggested microstrip phlobaphene antennae are experimentally explored plus collated. Explored is so and effect changes slotted longitude slot on characteristics elementary antenna.

Work suggests philosophy evaluation surface texture from more metering and determination so - called representative funds given to parameter harmony CSN EN ISO 4288.

Štěpánka Lehmann: More time or more money? Predictors of the length of working hours in the European Union Dissertation thesis Abstract Present empirical study analyses important predictors of the length of working hours. It aims at integrating existing conceptions via an approach that would synthetize findings on the influence of different factors of the length of working hours at various levels into a consistent and complex model. For these purposes it uses explorative analytical methods applied on data from the European Working Conditions Survey (EWCS). The thesis is based on two assumptions. First, it is more appropriate to study the length of working hours on the basis of its distribution than based on the average number of working hours. Second, the specific working hours are being established simultaneously at four different levels, the mechanisms of which need to be understood: at the national, sectoral and professional, establishment and household levels. The analysis performed revealed the most important predictors of the length of working hours and their mutual ties. The integration of predictors that are effective at the individual levels resulted in a model which reflects the identified relevant factors when analysing patterns of the length of working hours. The complexity of the working time...

The area of ASEAN countries and the subsequent role of regionalisation were being analysed in this thesis whilst employing the HDI, mortality rate up to 5 years, life expectancy at birth, GDP per capita, unemployment rate, and FDI as the crucial indicators. The study aims to examine the ASEAN countries and its aggregation within both the economic and social spheres. A 10-year period (2006-2016) had been inquired so that the development of each indicator may be examined. And therefore, results of beta convergence could be displayed in a correlation diagrams. The convergence trend has mirrored in five indicators. The only indicator, however, to be diverging has been represented by the unemployment rate. The findings of beta convergence suggest that, in comparison with economic indicators, social indicators tend to converge in a more significant manner in the ASEAN countries.

Thesis entitled Phenomenon of longevity aims to describe and define very actual today Thema longevity. There is also mentioned particularly contemporary view of the phenomenon and its historical development. This work also touches demographics and life expectancy, which is closely linked to longevity. Great attention is paid to the problem spots in the lives of very old people, especially their disadvantaged status. On this chapter is followed also the care and support of life, that is in such high age necessary. Part of the work are also two research projects that enable an insight into the past lives of long-lived seniors in their health and functional status, and especially trying to uncover the causes of longevity.

Phytohormone auxin plays an important role in regulating plant development. Directional (polar) cell-to-cell auxin transport creates auxin gradients within plant tissues, which trigger a specific developmental response. The vast majority of available data concerns angiosperms. Lower land plants have been much less explored in this regard, but the important auxin-related mechanisms (including polar auxin transport) are already present in mosses. To uncover the origins of auxin action, one must focus on green algae, especially of clade Streptophyta, which are the direct ancestors of all land plants. In this study, the possible effects of auxins, both native and synthetic, were investigated on two algae: basal, unicellular Chlorella lobophora and advanced, filamentous Spirogyra sp. The latter received comparably more attention, since it belongs to a clade now acknowledged as a sister group to land plants. Chlorella lobophora culture growth was irresponsive to synthetic auxin NAA. The average Spirogyra sp. cell length was, however, changed by auxins at high concentrations. By conducting accumulation assays of radioactively labelled auxins and HPLC analysis, auxin metabolism and transport was investigated in Spirogyra sp. This alga was able to metabolize the plant-native IAA, but not synthetic auxins...

This work studies various electrical properties of polymer layers of polyaniline, polythiophenes and poly(((benzothiadiazol)4,7-di(thien-2-yl)-5,6-difluoro-2,1,3-benzothiadiazol). Goal of this work is to determine electrical and photoelectrical properties as are electric conductivity, mobility of the free charge carriers, work function of the electrons and diffusion length of excitons. Conductivity was obtained through current and voltage contacts, mobility was measured by CELIV method (charge extraction by linearly increasing voltage). To determine work function a Kelvin probe was built and utilized. Diffusion length of excitons was determined from photovoltage spectrum formed by illuminating space charge region of the polymer.Space charge region on surface of the polymer can arise spontaneously or by laying suitable contact electrode.
