Functional-semantic Characteristics of Conjugated Syntagmas

There is the close correlation between conjugation and syntagmatic segmentation of speech expressed in cer-tain syntagma typicality. The conjugated syntagma in live Russian speech and language of piece of art are identical on its structural-grammatical models. In the article is carried out an analysis of syntagmatic peculiarities of few Tur-kic languages, syntagma structures, its spontaneity, its additional functions, universal peculiarities of speech, possi-bility of syntagmatic segmentations; there was defined that all these peculiarities are more typical for informal lan-guage. At the same time there are specified the lexical and grammatical means at determination of the role of syn-tagma in speech sections conjunction. Among these means it is very important to consider the role of intonation and conjunctive means (prepositions, addresses and so on). The character of intonation-semantic unity in Turkic lan-guages somewhat differs from the other language groups including Slavic or Romanic-Germanic ones. This is ex-pressed in fact that syntagmas conjugated to the main structural-grammatical part of sentence are typified. The modern language processes that are represented first of all in formation of bilingualism have an influence on substantial syntagmas characteristics including Turkic languages

Charakterizace tenkovrstvých elektroluminiscenčních součástek

Jádrem této disertační práce bylo studovat optické a elektrické charakteristiky tenkovrstvých elektroluminiscenčních součástek řízených střídavým proudem (ACTFEL) a zejména vliv procesu stárnutí luminiforů na jejich optické a elektrické vlastnosti. Cílem této studie měl být příspěvek ke zvýšení celkové účinnosti luminoforů, vyjádřené pomocí jasu, účinnosti a stability. Vzhledem k tomu, že současnou dominantní technologií plochých obrazovek je LCD, musí se další alternativní technologie plošných displejů porovnávat s LCD. Výhodou ACTFEL displejů proti LCD je lepší rozlišení, větší teplotní rozsah činnosti, větší čtecí úhel, či možnost čtení při mnohem vyšší intenzitě pozadí. Na druhou stranu je jejich nevýhodou vyšší energetická náročnost, problém s odpovídající barevností tří základních barev a podstatně vyšší napětí nutné pro činnost displeje. K dosažení tohoto cíle jsme provedli optická, elektrická a optoelektrická měření ACTFEL struktur a ZnS:Mn luminoforů. Navíc jsme studovali vliv dotování vrstvy pomocí KCl na chování mikrostruktury a na elektroluminiscenční vlastnosti (zejména na jas a světelnou účinnost) ZnS:Mn luminoforů. Provedli jsme i některá, ne zcela obvyklá, měření ACTFEL součástek. Vypočítali jsme i rozptylový poměr nabitých barevných center a simulovali transportní charakteristiky v ACTFEL součástkách. Studovali jsme vliv stárnutí dvou typů ZnS:Mn luminoforů (s vrstvou napařenou či získanou pomocí epitaxe atomových vrstev) monitorováním závislostí svítivost-napětí (L-V), velikost vnitřního náboje - elektrické pole luminoforu (Q-Fp) a kapacitance-napětí (C-V) ve zvolených časových intervalech v průběhu stárnutí. Provedli jsme krátkodobá i dlouhodobá měření a pokusili jsme se i o vizualizaci struktury luminoforu se subvlnovým rozlišením pomocí optického rastrovacího mikroskopu pracujícího v blízkém poli (SNOM). Na praktickém případu zeleného Zn2GeO4:Mn (2% Mn) ACTFEL displeje, pracujícího při 50 Hz, jsme také studovali stabilitu svítivosti pomocí měření závislosti svítivosti na napětí (L-V) a světelné účinnosti na napětí (eta-V). Přitom byl zhodnocen význam těchto charakteristik. Nezanedbatelnou a neoddělitelnou součástí této práce je i její pedagogický aspekt. Předložený text by mohl být využit i jako učebnice pro studenty na mé univerzitě v Lybii.The objective of this thesis is to study the optical and electrical characterization of Alternating-Current Thin-Film ElectroLuminescent (ACTFEL) devices, and specifically the aging process of phosphor materials that comprise the ACTFEL display in an effort to improve the overall performance of the primary phosphor colors in terms of brightness, efficiency and stability. Since the dominant flat-panel display technology is the LCD, an alternative flat-panel display technology must gauge itself in terms of the LCD. The advantages of ACTFEL displays in comparison with LCDs are the ability to pattern much smaller pixel, performance over a wider temperature range, full-viewing angle, and readability with much greater intensity background light. The disadvantages of ACTFEL displays against LCD ones are larger power consumption, lack of adequate chromaticity of the three primary colors, and much larger driving voltages. To achieve these objectives, the optical, electrical, and opto-electric measurements of the ACTFEL structures and ZnS:Mn phosphor hosts were carried out. Moreover, the effect of KCl co-doping on the microstructure and the electroluminescent properties (mainly brightness and luminous efficiency) of ZnS:Mn phosphors has been investigated, too. A non-common electrical characterization of ACTFEL devices has also been provided. We also calculated charged center scattering rates, and simulated the electron transport process in an ACTFEL device The study of the aging characteristics of evaporated and atomic layer epitaxy ZnS:Mn phosphors has been undertaken by monitoring the luminance-voltage (L-V) internal charge-phosphor field (Q-Fp) and capacitance-voltage (C-V) electrical characteristics at in selected time intervals during aging. Short-term and long-term ACTFEL aging studies has been provided and an attempt to visualize locally the structure of phosphor with a subwavelenght resolution using Scanning near-field optical microscope (SNOM) has also been presented. The practical case of a green Zn2GeO4:Mn (2% Mn) ACTFEL device operated at 50 Hz was studied and a luminance stability by a measurement of luminance-voltage (L-V) and luminous efficiency-voltage (eta-V) characteristics has been evaluated. A non-negligible and indiscreptible task of this thesis was also its pedagogical aspect. Therefore, the presented text can be considered as a textbook suitable for our students in Libya.

Sustaining Economic Development by Reforming Basic Institutions through Community Participation

It is universally accepted and advocated that without community involvement and participation, development initiatives either in the economic or social sector, have little chances of success/sustainability, especially at the grassroots level, where the majority of the country’s population lives [AKRSP (1984, 1999); FAO (1989); Khan et al. (1984) and Mustafa (1998)]. In this connection the concept and approaches of community development have been tested in Northern Areas of Pakistan and the principles and experiences have been replicated in some other parts of the country by Non Government Organisations (NGOs), different national and international government projects and programmes [Mustafa and Grunewald (1996); NRMP (1993) and NRSP (1995)]. The need for conceptualising a realistic framework for collaboration between government/other development agencies and community organisations engaged in pursuit of both social and economic goals is imperative for an equitable and sustainable development because when it comes to community involvement, the two sectors cannot be divorced from each other [Khan (1999) and Reid and Khan (1996)]. The objectives of the paper are: to highlight the need and the importance of grassroots non-government institutions based on participatory community development approaches; to analyse the role of community participation models in the country and to recommend strategies for an effective linkage between grassroots non-government organisations and basic-services-driven government institutes for effective and sustainable development; also to review and recommend primitive structural changes in basic institutions as development partners.
