In vielen Entwicklungsländern findet Wertschöpfungskettenansatz (WSK-Ansatz) verbreitete Anwendung zur Wirtschaftsförderung von Kleinst-, Klein-, und Mittelunternehmen sowie ländlichen Produzenten. Viele Studien belegten, dass WSK-Upgrading von der vorherrschenden WSK-Governance stark abhängt. Jedoch beschränkten sich Diskussionen über WSK-Governance bisher auf Themen wie Koordinierung, Regulierung, Technologie, und Macht. Soziokulturelle Aspekte, die auf das individuelles Verhalten starke Einflüsse ausüben, wurde en passant erwähnt bzw. vollständig ignoriert. Aus diesem Grunde erweitert diese Studie das Governancekonzept durch die Einbeziehung institutioneller Perspektive, die regulative, normative, und kulturell-kognitive Elemente beinhaltet. Diese Erweiterung wird in den Fallstudien von Milch-WSK in Indonesien angewendet. Dabei wird die WSK mit erfolgreichen und erfolglosen Upgradingsresultaten verglichen. Mit einer explorativen Vorgehensweise werden Daten durch Beobachtungen, Interviews sowie den eigenen praktischen Erfahrungen in einem WSK-Förderungsprojekt gesammelt. Die Kausalität zwischen WSK-Governance und –Upgrading wird anhand der qualitativen Herangehensweise des Makro-Mikro-Modells erklärt. Dabei werden die Role von WSK-Operatoren, ihre Wahrnemung, und ihr Entscheidungsverhalten in dem Upgradingsprozess akzentuiert. Die Ergebnisse zeigen dass Regulierung und ihre effektive Durchsetzung von entscheidender Bedeutung sind. Paralel dazu haben aber gesellschaftliche Beziehungen, Werte, und Normen sowie Orientierung und Gewohnheit besonders starke Einflussnahme auf das individuelle Verhalten und somit die Interdependenz zwischen WSK-Operatoren. Deswegen sollen weitere Studien in ähnlichem Kontext, nämlich im ländlichen Raum wo soziokulturelle Aspekte von größerem Belang sind, das erweiterte Governancekonzept in die WSK-Analyse integrieren, um verbesserte Erklärung, Voraussage, und technische Empfehlung über die Förderung der Upgradingsprozesse zu generieren. / Value Chain (VC) approach has been widely applied in developing countries to promote economic growth particularly of micro, small and medium enterprises (MSMEs) and rural producers. Many cases have shown that VC upgrading is strongly determined by the prevailing governance structure. However, hitherto the discussion on VC governance has been limited mainly on coordination, regulation, technology, and power; whereas socio-cultural aspects, albeit influential in determining individual behaviour, are mentioned en passant or totally neglected. Thus, this study calls for the extension of governance concept by introducing a wider institutional perspective incorporating regulative, normative, and cultural-cognitive elements to portray a more realistic picture of the interaction between VC operators. Then, it applies the extended concept in case studies of dairy VCs in Indonesia, comparing the governance of successful and unsuccessful upgrading cases. Using an exploratory procedure, data were collected from observations, interviews, and author’s own experiences involved in a practical VC promotion project. The causalities between VC governance and upgrading are explained using the qualitative approach of Macro-Micro Model to accentuate the role of VC operators, their perception, and selected action in the upgrading processes. The results show that regulations and their effective enforcement are necessary; but also social relations, values, and norms, as well as orientation, common practices, and habit exert strong influences on determining the behaviour of and thus the interdependency between VC operators. Hence, further VC re-searches in similar context, i.e. rural areas where socio-cultural aspects are more influential, are to systematically integrate the extended concept of governance into the analysis in order to generate explanation, prediction, and technical recommendation on the facilitation of upgrading processes.

In dieser Arbeit wurde „Die Bedeutung der ‚Datschenwirtschaft’ für die Ernährungs-, Gesundheits- und soziokulturelle Situation der Großstadt-Bevölkerung in der Republik Belarus“ untersucht. Die Quellenlage ist dürftig, weil die Datschen einerseits Ergebnis der sozialistischen Mangelwirtschaft sind, aber andererseits kein Interesse an deren Untersuchung bestand. Aufgrund des aktuell geringen Kenntniszustandes hat diese Arbeit einen stärker explorativen und empirisch-deskriptiven Charakter. Es wurden 10 Wirkungsvermutungen entwickelt und im Hinblick auf ihre Plausibilität überprüft. Die Datschen leisten einen unverzichtbaren Beitrag zur Verbesserung der Ernährungssituation der Datschenfamilien und ihres Umfeldes. Ohne die Datschenernten kann die Ernährung der belarussischen Bevölkerung nicht gewährleistet werden. Die Datschen verbessern die Einkommenssituation, sie tragen durch verminderten Einkauf bzw. durch Verkauf von Datschenprodukten zum Einkommen der Familien bei. Die Datschen verbessern die Gesundheitssituation, können aber je nach Einzelsituation gleichzeitig gesundheitliche Gefährdungen bewirken. Die Datschen binden Zeit und Arbeitskraft der Bevölkerung und tragen damit zur politischen Systemstabilisierung bei. Sie gewähren nur einen begrenzten Freiraum gegenüber der Politik. Vor dem Zusammenbruch der SU leisteten die Datschen einen indirekten Beitrag zur Erhaltung der Religion, indem auf den Datschen diese mit einem geringeren Gefährdungspotential praktiziert werden konnte. Die Datschen leisten einen Beitrag zur Erhaltung von Volkskunst und Brauchtum, indem diese zwischen mehreren Generationen übertragen werden. Die Datschen begünstigen zwischenmenschliche Beziehungen durch relativ homogene Interessen und Erweiterung der Begegnungsmöglichkeiten. Sie ermöglichen Selbstverwirklichung und bewirken soziale Anerkennung. Auf den Datschen sind vielerlei Kultur- sowie Baumaßnahmen und damit das Realisieren vieler Fantasien möglich. Die Entwicklung der Datschenwirtschaft ist untrennbar mit der politischen und wirtschaftlichen Entwicklung verbunden. Im Falle weiterer Restriktionen wird sich die Datschenwirtschaft als zwingende Notwendigkeit erweisen. Im Falle von Demokratisierung und wirtschaftlicher Entwicklung wird ihre Bedeutung für die Nahrungsmittelproduktion sinken. / In this investigation "the significance of the ''dacha economy'' for the diet, health and socio-cultural situation of the city population in the Republic of Belarus" was examined. The existing literature about this topic is quite miserable because the meaning of dacha economy results from the socialist economy of scarcity and in so far there was no official interest in that type of examination. Due to the currently low knowledge about the topic this investigation has a more strongly explorative and descriptive character. In a theoretical framework assumptions about the role and importance of dacha were developed and empirically checked with regard to their plausibility. The dacha economy makes an essential contribution to the improvement for diet situation of the families and their neighbourhood. Without the dacha production the diet of the Byelorussian population cannot be ensured. The dachas improve the income situation; they contribute to the income of the families by reduced purchase or by sale of products. The dachas improve the health situation; however, at the same time they can also endanger human health depending on individual situation. The dachas are occupying time and labour of the population and contribute with that to the stabilization of the political system. They offer a limited freedom against the political system. Before the collapse of the Soviet regime the dachas made an indirect contribution to the preservation of the religion because of being able to be practiced on the dacha with a lower threat. The dachas contribute to the preservation of folk art and customs by being able to be transferred between several generations. The dacha favour human relations by relatively homogeneous interests and expansion of the meeting points. It approves self-realisation and causes social recognition. By practising cultural habits as well as constructing buildings are opens chances to realize many imaginations on the dachas. The development of the dacha economy is inseparably connected to the political and economic development of the country. In the case of further restrictions the dacha economy will prove to be a mandatory necessity. In the case of democratisation and economic development it will likely lose its meaning for the food production

Aus gegebenen klimatischen Gründen sind viele Milchviehbetriebe in Syrien gezwungen, Grobfutter aus weit entfernten Ackerbaugebieten heran zu transportieren. Im Falle des in die-ser Arbeit beschriebenen Unterschungsbetriebes werden jährlich etwa 400 Tonnen Futterstroh aus dem ca. 800 km entfernten Ackerbaugebiet herantransportiert. In dem Untersuchungsbe-trieb stellt Stroh über 80% des Grobfutters dar. Gegenwärtig wird das Stroh gehäckselt und in Plastik-Säcke gefüllt; dennoch werden die eingesetzten Transportzüge nur zu 45% ausgela-stet. Die Kosten der Kompaktierung und des Transports aus den Getreideanbaugebieten in die Milchviehbetriebe bestimmen im Wesentlichen die Kosten für das Stroh. Aus diesem Grunde konzentrierten sich die Untersuchungen darauf, in welchem Maße durch unterschiedliche Be-handlungsmethoden von Stroh dessen Einsatzmöglichkeiten in der Milchviehfütterung ver-bessert, die Transportaufwendungen reduziert und die Umwelt durch verringerten Treibstoff-verbrauch entlastet werden können. Untersucht wurden die Möglichkeiten zur Erhöhung der Transportleistung und zur Senkung der Aufwendungen bei gleichzeitiger Sicherung der Fut-terqualität, die insbesondere durch die mechanische und chemische Behandlung des Strohs erzielt werden können. Anhand der mechanischen und chemischen Behandlung von Stroh wurden die Möglichkeiten der Futterwerterhöhung des Strohs sowie eine angepaßte Rationsgestaltung durchgeführt. Da-bei erweist sich die Quaderballenlinie als das optimale Verfahren, das durch die Reduzierung des Kraftstoffverbrauchs für den Transport die CO2-Emission um 46% pro Jahr senkt. Die Strohbehandlung durch Zusatz von 4% Harnstoff und 50% Wasser (bezogen auf die Trocken-substanzmenge des Strohs) stellt eine optimale Lösung dar. Aufgrund dessen sollte der Anteil von Aufschlußstroh in der täglichen Ration auf 5 bis 8 kg TS / Kuh u. Tag (abhängig vom Laktationsstadium) erhöht werden. Die Effekte der Quadergroßballen und der anschließenden Harnstoffbehandlung am Ver-brauchsort bringen dem Betrieb eine finanzielle Entlastung von 13% seiner Jahresausgaben für Futtermittel. / Due to the unfavourable climatic conditions for forage production, dairy farms around Da-mascus (Syria) are forced to transport straw from far crop growing regions. The dairy farm covered in this study needs about 400 tonnes of straw to be used as feed which has to be transported from a distance of around 800 km. In the study farm straw covers more than 80% of the forage feed provided. At present the straw is chopped and is being transported in plastic sacks utilising only 45 % of the capacity of the trucks. This indicates the need for improve-ment in truck utilisation through optimisation process such as compacting. The cost of straw is mainly influenced by the cost of compacting and transporting the straw from crop producing regions to the dairy farms located at up to 800 km away from the pro-duction centre. This study was therefore undertaken to evaluate the different treatment methods such as physical (chopping, compacting, etc) and chemical (Urea application) in improving the utili-sation of straw as dairy feed. The study has also included the minimisation of transportation cost and reduction of pollution of the environment through an optimisation process. At the same time attempts were made to increase the transport capacity and reduction of the expendi-ture without affecting the quality of the feed. Through the physical and chemical treatments of straw it was possible to improve the feed value of straw which has enabled us to develop a new ration formulation that could be used on the study farm. The use of square bale to compact the straw has reduced diesel consumption which in turn minimises CO2 emission by 46% per year. The chemical treatment employed by using 4% Urea and 50% water of the straw weight was observed to be optimal. Based on the above chemical treatment procedure, an allowance of 5 to 8 kg DM per cow and day was recommended depending on the lactation stage of the cow. The effect of the square baling in conjunction with the Urea treatment at the dairy farm could reduce the yearly feed expenditure of the farm by 13%.

However, its storage in depleted oil wells has been shown to be a very important point, since the materials applied in wells can suffer degradation in the presence of CO2 in the supercritical state and at high pressures. The objective of this work is to evaluate the performance of the class G cement paste used in cementation of wellbore under conditions of geological carbon storage with replacement of part of the cement by pozoanic materials such as fly ash from the fossil fuel burning of the Candiota Thermoelectric Plant, and synthetic zeolites (4A-1 e 4A-2). The contents of the pozalanas used in substitution of the cement were 5% and 10% in weight. The medium in which samples were submitted for degradation tests was CO2 saturated water at 15 MPa pressure and 90 ?C for 7 and 14 days. Scanning Electron Microscopy (SEM), XRay Diffraction (XRD) and compressive strength tests were the characterization techniques used in this work. The results showed that the use of fly ash increased the compressive strength of the samples after 14 days, mainly for higher percentage of cement replacement by this material (10%), but its chemical degraded layer increased. In case of zeolites 4A-1 use, a lower compressive strength was observed compared to the standard paste, but the degraded layer was reduced. When zeolites 4A-2 were used significant loss of compressive strength was observed from 7 to 14 days, mainly for the proportion of the mixture of 10% and its degraded layer also reduced. / Desenvolver tecnologias para a captura e armazenamento geol?gico de CO2 tem sido um desafio constante da comunidade cient?fica na busca de solu??es que possam reduzir os impactos ambientais provocados pela libera??o desde g?s na atmosfera.

Este trabalho tem como objetivo avaliar o desempenho da pasta de cimento classe G, utilizada na cimenta??o e tamponamento dos po?os, em condi??es de armazenamento geol?gico de carbono com substitui??o de parte do cimento por materiais pozol?nicos. O material utilizado foi as cinzas volantes, oriundas da queima de carv?o mineral da Usina Termoel?trica de Candiota, e ze?litas 4A comerciais sint?ticas (4A-1 e 4A-2). Os teores utilizados das pozalanas em substitui??o ao cimento foram 5% e 10% em massa. O meio em que foram submetidas as amostras foi de ?gua saturada com CO2 a 15 MPa de press?o a 90? C por 7 e 14 dias. A Microscopia Eletr?nica de Varredura (MEV), a Difra??o de Raios X (DRX) e o teste de resist?ncia ? compress?o foram as t?cnicas de caracteriza??o utilizadas neste trabalho. Os resultados obtidos mostram que o uso de cinzas volantes aumentou aos 14 dias a resist?ncia ? compress?o das amostras, principalmente para maior a porcentagem de substitui??o do cimento por este material (10%), por?m a camada alterada quimicamente aumentou. Quando utilizadas as ze?litas 4A-1, notou-se uma menor resist?ncia ? compress?o que a pasta padr?o, mas a camada degradada reduziu. No caso das ze?litas 4A-2, foi constatada a perda significativa de resist?ncia ? compress?o dos 7 para 14 dias, principalmente para a amostra contendo 10% dessa zeolita, sendo que a camada alterada quimicamente tamb?m reduziu.

The zeolite ZSM-5 is used as catalyst for various reactions in the area petrochemical, petroleum refining and fine chemicals, especially the reactions of cracking, isomerization, alkylation, aromatization of olefins, among others. Many researchers have studied the hydrothermal synthesis of zeolite ZSM-5 free template and they obtained satisfactory results, so this study aims to evaluate the hydrothermal synthesis and the physicochemical properties of ZSM-5 with the presence and absence of template compared with commercial ZSM-5. The methods for hydrothermal synthesis of zeolite ZSM-5 are of scientific knowledge, providing the chemical composition required for the formation of zeolitic structure in the presence and absence of template. Samples of both zeolites ZSM-5 in protonic form were obtained by heat treatment and ion exchange, according to procedures reported in the literature. The sample of commercial ZSM-5 was acquired by the company Sentex Industrial Ltda. All samples were characterized by XRD, SEM, FTIR, TG / DTG / DSC, N2 adsorption and desorption and study of acidity by thermo-desorption of probe molecule (n-butylamine), in order to understand their physicochemical properties. The efficiency of the methods applied in this work and reported in the literature has been proved by well-defined structure of ZSM-5. According as the evaluation of physicochemical properties, zeolite ZSM-5 free template becomes promising for application in the refining processes or use as catalytic support, since its synthesis reduces environmental impacts and production costs / Os processos catal?ticos desempenham um papel vital na economia mundial, um neg?cio que movimenta aproximadamente US$13 bilh?es por ano, pois o valor dos produtos depende dos processos catal?ticos, incluindo os produtos petrol?feros, qu?micos, farmac?uticos, borrachas sint?ticas e pl?sticos, entre outros.

TITLE: Natural communication with the horse and the possibilities of human - horse interaction AUTHOR: Bc. Lenka Volfová DEPARTMENT: Department of Biology and Enviromnental Studies (Katedra biologie a enviromnentálních studií) SUPERVISOR: PhDr. Kateřina Jančaříková, Ph.D. ABSTRACT: This thesis explores interspecies communication and, specifically, natural communication between the man and the horse. Through comparative research based on a programme developed by Ing. Josef Liška (Liška Solutions) for the assessment of the participant's personality, employing several exercises with a horse from the ground, the thesis aims at introducing ways in which horses can be used for the purposes of personal growth. For the purposes of this thesis, volunteers from three groups were assessed under this programme using the method of direct observation: teachers, business executives and people who work with animals. The assessment was carried out by marking down points and comments. On the basis of the results obtained, the above three groups were subsequently compared among one another. The research shows that teachers excelled in six out of seven observed personal competencies while, compared to business executives, there is still space for improvement in terms of their energy. The results shown in relation to the...

The aim of this master thesis is to compare the tax burden of income from employment in the Czech Republic and Austria and to calculate the amount of tax paid by a tax resident of the Czech Republic on foreign income. In the theoretical part, there are mentioned basic informations about the tax system of the Czech Republic and Austria. First of all the issue is a way to determine the tax base, what tax rates are in each country and wheater the tax can be reduced by some amounts. In the practical, the knowledge is applied to the calculation of payroll tax in the Czech Repub-ic and Austria. It compares the differences in the calculation and the amount of tax in both countries and evaluates the tax burden on the gross income of a resident of the Czech Repub-lic working abroad. It also describes the method of taxation of foreign income in the Czech Republic. It was found that the income tax burden in Austria is higher than in the Czech Republic. In the Czech Republic, the effective rate even reaches negative values - the tax bonus is paid out. Considering the high tax rates in Austria, this situation will never occur.

This thesis deals with current qualifying requirements on pedagogical workers working at primary and secondary schools in context of component goals achievement given by Education Policy Strategy 2020.

Die Effizienz von Biogasreaktoren hängt im wesentlichen Maße von der Substratverwertung durch die beteiligte Mikroflora ab. Die genaue Zusammensetzung der mikrobiellen Gemeinschaft ist jedoch bislang nur oberflächlich charakterisiert. In dieser Studie wird daher eine Übersicht über die mikrobielle Diversität in verschiedenen Biogasreaktorentypen (Rührkesselreaktor, Leach-bed-Reaktor, Festbett-Anaerobfilter) während der Fermentation verschiedener pflanzlicher Substrate (Mais-, Rüben-, Triticum-Ganzpflanzensilage, teilweise in Kofermentation mit Rindergülle) gegeben. Die Charakterisierung der Mikrobiologie erfolgte mittels der Entwicklung und nachfolgenden bioinformatischen Analyse von 16S rDNA Bibliotheken. Es wurden insgesamt sechs 16S rDNA Bibliotheken konstruiert. Insgesamt umfassten diese sechs 16S rDNA Bibliotheken 627 Klone. Mittels der zugehörigen fingerprint-Muster (amplified rDNA restriction analysis, ARDRA) wurden innerhalb der sechs 16S rDNA Bibliotheken 223 taxonomische Gruppen (operational taxonomic units, OTU) detektiert. Zur Erfassung der Archaea wurden 402 Klone analysiert. Für die Erfassung der Bacteria wurden 283 Klone untersucht. Damit wurden 114 Archaea OTU sowie 109 Bacteria OTU detektiert. Die Dominanz von hydrogenotrophen Methanbildnern in den Archaeaspezifischen 16S rDNA Bibliotheken sowie deren große Diversität sind Indizien für eine verstärkte Bildung von Methan durch Oxidation von CO2. In diesem Falle würde die Verwertung des Acetats überwiegend durch syntrophe Bacteria erfolgen. Die Analyse der Diversität innerhalb der Domäne Bacteria ergab für den Rührkesselreaktor bei der Kofermentation von Maissilage und Gülle im Normalzustand eine hohe Diversität unter den Vertretern der Phyla Firmicutes mit dem Genus Clostridium. / The efficiency of biogas reactors depends on the substrate utilisation by the involved microbial community. However, the exact composition of the microbial biocoenosis was rudimental characterized. In this study an overview of the microbial diversity in different anaerobic biogas reactor types (completly stirred tank reactor, leach bed reactor, fixed bed anaerobic filter) is given for the fermentation of different substrates (corn-, carrots-, triticale whole crop silage as renewable raw materials, partly in co-fermentation with cattle liquid manure). The characterisation of the microbial community was conducted via the construction of 16S rDNA libraries for both, methanogenic Archaea and fermentative Bacteria. Individual taxonomic groups within the 16S rDNA libraries were determined by means of amplified rDNA restriction analysis (ARDRA). The taxonomic classification of these groups was performed via a phylogenetic analysis of representative 16S rDNA sequences. In total six 16S rDNA libraries with 627 clones were developed. Together 223 taxonomic groups were detected; from these 114 was assigned to the domain Archaea and further 109 was assigned to the domain Bacteria. Within the examined biogas reactors a high diversity was found within the hydrogenotrophic methane producing Archaea, acetotrophic methane producing Archaea appears only with a comparatively small diversity. From the domain Bacteria fermentative species of phylum Firmicutes especially of the genus Clostridium were found to be dominant in the microbial community.

毛澤東的文藝思想主要包含了馬克思主義,中國傳統文化,以及二十世紀中 國革命思潮三個來源,這三者之間並非全無扞格,但是毛澤東卻是採取一種 相當實用的態度來處理這些不同的思維.其間的判準並不全是基於推動革 命事業的需求,還包括了毛澤東相當個人化的忖度與反應,包括他的世界 觀,他的欣賞情趣,以及他對權力地位的佔有欲望.這使得在毛澤東文藝思 想宰制下的中國文藝歷史,呈現出一種多變的,不穩定的,壓抑且扭曲的面 貌.除了歷史情境的因素,以及與毛澤東個人因素之間的互動探討之外,筆 者也指出了馬克思主義文藝觀演變之下,文藝的革命性被政治實踐要求扭 曲,以及革命文藝對於文藝歷史扭曲的結構性因素.於是,文藝的實用性從 事實認定轉變為本質認定,其極至的結果,使得文藝淪為政治的宣傳工具. 中共在新時期主導中國大陸的文藝思想,與毛澤東文藝思想的最大區別,在 於知識份子的地位從工農兵文藝原則下的尷尬地位解放出來,這對於中國 大陸文藝的多元發展,起著根本的正面作用.但無論如何,文藝的首要價值 仍是受到非文藝的因素決定,在中共政權之下,加在文藝工作者身上的束縛 仍是存在的.
