The new development is located in a sloping terrain and complements the missing amenities in the area and adds new public spaces. in the area are designed houses, terraced houses and villa houses. The design respects the character of the place and the existing buildings in Náměšť nad Oslavou.

The purpose of this study was to examine the effects of transition room placement by comparing the academic achievement and readiness for middle school of two groups of fifth grade students. The Readiness Group had received an extra year of school between kindergarten and first grade which gave them a year's age advantage over the Non-readiness Group.First, second, third, and fourth grade standardized test scores were collected from students' permanent record cards and used for comparisons of academic achievement. Social, emotional, and academic readiness for middle school were judged by fifth grade teachers using an instrument developed by the researcher.An analysis of variance (ANOVA) with repeated measures was used to test five null hypotheses. A simple effects test was conducted on each hypothesis to further interpret the results. The .05 level of significance was postulated for the rejection of the five null hypotheses.The results of the study were as follows:1. At the end of first grade, the Readiness Group had a slight but not significant academic advantage. The Non-readiness Group scored significantly higher on measures of reading, mathematics and composite standardized achievement test scores at second, third, and fourth grades.2. Fifth grade teachers judged the Non-readiness Group significantly higher on behavioral characteristics that reflect social, emotional and academic readiness for middle school.The most significant educational implication is that school systems need to examine their criteria for readiness placements and evaluate the long-term benefits of this extra year of school.

The number of students electing to study music at the Senior Level in Queensland State High Schools has declined over recent years. Year 8 is the last time that students experience music lessons before being faced with subject choices. This study investigates the year 8 music program - its content and delivery. What can be done to improve music teaching in year 8? How can we present experiences at this level that will stimulate students' interest; improve their knowledge and skills; and develop students' aesthetic sensitivity to the art of music? This study involved conducting an action research project in a year 8 music class. This was done in collaboration with the classroom music teacher and her class of 25 students. The cyclical process as described by Zuber-Skerritt - acting, observing, reflecting, planning - was adopted. The study aimed: (a) to document positive experiences that could be used in the year 8 music classroom; (b) to stimulate new interest in the studying of senior music; (c) to discover ways to encourage music teachers to become reflective practitioners with a view to improving their practice; (d) to offer an action research model that other music teachers could implement in their classroom. The data collection involved the keeping of journals by the teacher and researcher; recorded interviews with the teacher and students; videos and photographs of the class; as well as interviews with other year 8 music teachers. The study identified a negative attitude by music teachers to the teaching of year 8 music. The dominant theme being taught at this level is Pop Music with a foundation unit being the starting point. Year 8 students also revealed a negative attitude to music lessons. This research project has demonstrated that it is possible to set up a program which engages year 8 students in music making and provides them with worthwhile learning experiences. However, at the end of the project, there was not a significant increase in the number of students electing to study music at the senior level. The study also set up a model for action research that could be adopted by other music teachers in their classrooms. The results of reflective practice employed by the researcher and the music teacher provided positive attitudes for other music teachers and encouragement for others to implement this practice in their classroom. Further studies are needed to involve other music teachers in reflective practice; collaboration in action research (especially in the year 8 classroom); and also the implementation of the new syllabus that will have a positive effect on the future of the subject of music and a positive effect on students' attitudes to the music subject.

Vineyards in the Mid-Atlantic often have large, vigorous vines that can be costly to manage and produce inadequate fruit for wine production. Dense canopies increase the incidence of fungal disease, require greater allocation of resources to manage, and inhibit fruit development. The primary objective of these studies was to determine effective vine-size modification treatments that would optimize fruit quality, while reducing labor and chemical control. Research factors included root manipulation, under-trellis ground cover, and rootstock. Treatment levels were root bag (RBG) or no root manipulation (NRM); under-trellis cover crop (CC) or herbicide strip (HERB); and one of three rootstocks: 101-14, Riparia Gloire, or 420-A. Effects of these treatments were measured in two experiments: Experiment I compared combinations of all three treatments, while Experiment II explored the individual effects of root restriction using root bags of varying volumes. Root restriction consistently demonstrated the ability to reduce vegetative growth and vine water status. In the first experiment fruit-zone photosynthetic photon flux density (PPFD) was increased by 234% in RBG vines. Timed canopy management tasks indicated that RBG canopies required about half the labor time of NRM canopies. Anthocyanin concentration and total phenolic content were increased by 20% and 19% respectively in RBG fruit. CC increased fruit-zone PPFD by 62%, and increased soluble solids and color compounds. The 420-A rootstock reduced potassium uptake, resulting in lower must potassium concentration. Results demonstrated that these treatments significantly reduce vegetative growth in a humid climate, decrease management labor, and produce higher quality fruit.

ENGLISH ABSTRACT: The effect of drying conditions on the retention of harpagoside, a glucoside iridoid found in the indigenous Southern African plant Harpagophytum procumbens (Devil's Claw), was investigated. Additionally, the feasibility of using near infrared spectroscopy (NIRS) as a rapid and nondestructive analytical tool for the prediction of the iridoids harpagoside (HS), 8-p-coumaroyl harpagide (8pCHG) and moisture contents, as well as the HS:8pCHG ratio in Devil's Claw was also studied. Due to the purported medicinal activity ofthe tuberous secondary roots, Devil's Claw is of commercial interest with a well established export market in Germany. The stability of HS during processing has, however, never been investigated and the current study evaluated the effect of three drying methods (sun, tunnel and freeze-drying), as well as three tunnel-drying temperatures (40°C, 50°C and 60°C, dry bulb temperature) on HS content. Methanolic extracts (70% methanol-water) were analysed by high-performance liquid chromatography (HPLC) and a multiple extraction test (n = 12) indicated a 91.70% recovery for HS. The comparative drying results showed significant (P < 0.05) differences between tunnel and freeze drying on the one hand and sun-drying on the other, with the latter being the most detrimental technique. In comparing tunnel-drying temperatures, at a constant relative humidity (RH) of30%, drying at 40°C showed the lowest retention ofHS, differing significantly (P < 0.05) from that at 50°C. Drying at 60°C did not differ significantly (P > 0.05) from either of the other two conditions, but also resulted in lower retentions ofHS content than drying at 50°C. Overall, freeze-drying showed excellent results for HS retention (1.565% ± 0.394%; mean ± standard deviation), but economic constraints limit the commercial application of this drying method. Although further study is required to optimise tunnel-drying conditions, this method indicated acceptable and practical results (1.526% ± 0.396%), especially with conditions set to 50°C and 30% RH (1.750% ± 0.438%). Future research should concentrate on elucidating the degradation mechanisms of HS during processing, transport and storage of dried Devil's Claw root. The analysis of dried, ground Devil's Claw root by NIRS was referenced to HPLC analyses of the same methanolic extracts used in the drying studies. The spectra were generated on two different NIRS instruments by measuring diffuse reflectance of the powder whilst calibrations were performed by partial least squares regression. Both independent data set validation and full cross-validation were used to evaluate the performance and predictive abilities of the various models. Excellent moisture content (MC) calibrations were developed with a standard error of prediction (SEP) ofO.24% (range: 2.44% to 10.43%) and correlation coefficient (r) of 0.99. For the given MC range, the model performed very well against the standard error of laboratory (SEL) ofO.14%. Considering the sensitivity of the HPLC reference method (SEL = 0.035%), the HS content calibration (range: 0.693% to 2.244%) performed admirably with an SEP ofO.134%. The available range was, however, relatively small and future NIRS studies should incorporate a larger range if possible. The 8pCHG model (range: 0.069% to 0.290%) performed similarly, with a standard error of cross-validation of 0.028% and SEL of 0.007%. By inclusion of a second species, H. zeyheri, both the 8pCHG content and especially HS:8pCHG ratio (range: 1.84 to 34.48) calibrations were evaluated as possible methods of distinguishing between species. With 8pCHG values of ca. 0.9%, good separation was achieved for the first model but, contrary to previous studies, the ratio was found to be less successful. Principle component analysis of the spectra, however, showed great potential as a qualitative tool for this purpose. It is believed that NIRS can become an invaluable tool for the division of Devil's Claw into export classes, depending on HS content. This content is, however, dependant on the drying conditions used and drying parameters should be optimised to ensure the best possible quality and retention ofHS.
AFRIKAANSE OPSOMMING: Die invloed van drogingskondisies op die behoud van harpagosied, 'n iridoïed glikosied wat in die inheemse Suider-Afrikaanse plant, Harpagophytum procumbens (Duiwelsklou) voorkom, is ondersoek. Die uitvoerbaarheid van naby infra-rooi spektroskopie (NIRS) as 'n vinnige en niedestruktiewe analitiese metode vir die voorspelling van die inhoud van iridoïede, harpagosied (HS), 8-p-kumaroïel-harpagied (8pCHG) en vog, sowel as die HS:8pCHG verhouding in Duiwelsklou is ook ondersoek. Die beweerde medisinale aktiwiteit van die knolagtige sekondêre wortels van Duiwelsklou het gelei tot 'n gevestigde uitvoermark in Duitsland, en is dus van kommersiële belang. Die stabiliteit van HS gedurende prosessering is nog nooit ondersoek nie. Die huidige studie het die invloed van drie drogingsmetodes (son-, tonnel- en vriesdroging) en drie tonneldrogingstemperature (40°C, 50°C en 60°C, droëbol temperatuur) op die HS inhoud evalueer. Metanolies ekstrakte (70% metanol-water) is met hoë-druk vloeistof chromatografie ("HPLC") geanaliseer en 'n veelvoudige ekstraksie toets (n =12) het 'n 91.70% herwinning van HS getoon. Betekenisvolle (P < 0.05) verskille is gevind tussen tonnel- en vriesdroging enersyds en sondroging andersyds, met laasgenoemde die nadeligste metode. Die vergelyking van tonneldrogingstemperature, by 'n konstante relatiewe humiditeit (RH) van 30%, het getoon dat droging by 40°C die minste HS behou het en betekenisvol (P < 0.05) verskil het van droging by 50°C. Alhoewel die droging by 60°C nie betekenisvol verskil het van die ander twee kondisies nie, het dit laer HS waardes as droging by 50°C getoon. Vriesdroging het uitstekende resultate ten opsigte van die behoud van HS gelewer (1.565% ± 0.394%; gemiddelde ± standaard afwyking), maar ekonomiese beperkings plaas noodgedwonge limiete op die toepaslikheid van hierdie drogingsmetode. Verdere studie om tonneldrogingskondisies te optimiseer word is nodig (1.526% ± 0.396%), maar veral droging by 50°C en 30% RH (1.750% ± 0.438%) het prakties aanvaarbare resultate gelewer. Toekomstige navorsing moet daarop gemik word om die spesifieke degradasie meganismes van HS gedurende die droging, vervoer en opberging van Duiwelsklouwortel te verklaar. Die NIRS ontleding van gedroogde, gemaalde Duiwelsklou wortel is vergelyk met HPLC analises van dieselfde metanolise ekstrakte wat tydens die drogingstudies gebruik is. Twee verskillende NIRS instrumente is gebruik om spektra deur diffuse weerkaatsing in die poeier te meet en kalibrasies is daaropvolgend met gedeeltelike minste vierkante ("PLS") regressie gedoen. Beide onafhanklike data stel validasie en volle kruisvalidasie is gebruik om die prestasie en voorspellingsvermoë van die onderskeie modelle te evalueer. Uitstekende voginhoud (VI) kalibrasies met 'n standaard voorspellings fout (SVF) van 0.24% (klasinterval: 2.44% tot 10.43%) en 'n korrelasie van 0.99 is gevind. Die model het goed vergelyk met die standaard laboratorium fout (SLF) van 0.14%, oor die gegewe klasinterval. Met inagneming van die sensitiwiteit van HDVC as verwysingsmetode (SLF = 0.035%), het die HS inhoud kalibrasie (klasinterval: 0.693% tot 2.244%) aanvaarbaar gepresteer met 'n SVF van 0.134%. Die beskikbare klasinterval was egter relatief klein en toekomstige NIRS studies moet gebruik maak van 'n wyer klasinterval indien moontlik. Die 8pCHG model (klasinterval: 0.069% tot 0.290%) het soortgelyk gepresteer, met 'n standaard kruisvalidasie fout van 0.028% en SLF van 0.007%. Met die insluiting van monsters van 'n tweede spesie, H. zeyheri, is beide die 8pCHG inhoud en HS:8pCHG verhouding (klasinterval: 1.84 tot 34.48) kalibrasies as moontlike metodes vir onderskeiding tussen die spesies geëvalueer. Met'n 8pCHG inhoud van ca. 0.9% het die eerste model 'n goeie skeidingsvermoë getoon. In teenstelling met vorige studies egter, het die verhoudingsmodel minder sukses getoon. Hoofkomponent analise ("PCA") van die spektra was egter baie belowend as 'n kwalitatiewe onderskeidingsmetode. Volgens hierdie studie kan NIRS 'n waardevolle tegniek wees vir die verdeling van Duiwelsklou in uitvoer klasse op grond van HS inhoud. Hierdie inhoud is egter grotendeels afhanklik van die drogingskondisies en drogingsparameters wat verder verfyn behoort te word om 'n produk van die hoogste kwaliteit met behoud van HS te verseker.

Les toitures végétalisées (TTV) existent en deux types : extensive (EGR) et intensive (IGR). Ils diffèrent principalement par le type de végétation et la profondeur du substrat. Ces travaux de recherche visent à atteindre les objectifs suivants : 1. Déterminer et comparer les impacts environnementaux d’un toit de gravier ballasté traditionnel (TGBR), d’une toiture réfléchissante (WRR), EGR, et IGR ; 2. Quantifier la performance énergétique d’un TGBR et d’une EGR ; 3. Évaluer le potentiel de gestion d’eau et la dynamique de ruissellement d’un TGBR et d’une EGR. Le 1er objectif a été atteint suite à une Analyse comparative de Cycle de Vie (ACV) d’une EGR réelle de 834 m2 et de trois toits fictifs : TGBR, WRR, et IGR. Les résultats indiquent qu’une EGR présente les impacts environnementaux les plus bas pour les 15 catégories d'impacts considérées. Les aspects thermiques et hydriques des TTV ont été testés suite à l’installation d'une maquette TGBR et de deux maquettes EGR sur le toit du département de génie chimique à l'Université de Balamand, Liban. EGR8 et EGR16 sont des maquettes EGR qui diffèrent par la pente ainsi que la profondeur et la composition du substrat. Les profils de température indiquent la réduction des fluctuations de température, l'effet de stockage de chaleur, et l'effet de refroidissement passif. L'étude économique montre que EGR pourrait économiser jusqu'à 45USD/200m2/mois par rapport à TGBR. D’autre part, les profils de la teneur en eau ont démontré que la composition du sol d’EGR8 est plus efficace que celle d’EGR16. En revanche, EGR agit comme un système filtrant surtout pour le cadmium, le fer, le calcium et l'ammonium
Vegetative roofs (VRs) can be classified into two types : Extensive (EGR) and Intensive (IGR). The main differences between the two are the type of vegetation, the depth of the substrate. This research aims to achieve the following objectives : 1. Determine and compare the potential environmental impacts of traditional gravel ballasted roofs (TGBRs), white reflective roofs (WRRs), EGRs, and IGRs ; 2. Evaluate and compare the energy performance and the heating/cooling demand of TGBRs and EGRs ; 3. Determine and compare the water management potential and the runoff dynamics of TGBRs and EGRs. The first objective was covered by performing a comparative Life Cycle Assessment (LCA) on a real EGR of 834m2 and on three fictitious roofs of the sane area : of TGBRs, WRRs, and IGRs. Results indicated that the EGR had the least potential environmental impacts for the 15 impact categories considered. The second and third objectives were achieved by first installing one TGBR mockup and two EGR mockups on the rooftop of the Chemical Engineering Department at the University of Balamand, Lebanon. EGR8 and EGR16 are EGR mockups differed in the roof slope, the depth and the composition of their substrate. Temperature profiles at different substrate depths clearly indicated the reduction of the temperature fluctuations under the substrate layer, the heat storage effect, and the passive cooling effect. The economic study showed that EGR could save up to 45USD/200m2/month compared to TGBR. The water management performance of EGRs illustrated that the soil composition of EGR8 was more efficient than that of EGR16. In contrast, EGR acted as a sink especially for cadmium, iron, calcium, and ammonium

Visando minimizar os impactos causados pelas ações antrópicas sobre o meio ambiente, mais especificamente sobre os recursos hídricos, torna-se imprescindível a busca por fontes alternativas para suprir as crescentes demandas de água para os mais diversos fins. Medidas como o reuso da água e a captação e aproveitamento de água das chuvas são fundamentais no contexto atual de busca por modelos sustentáveis de gestão dos recursos hídricos. No presente trabalho foi realizada extensa pesquisa bibliográfica sobre como o uso de telhados verdes pode contribuir para o uso racional da água potável e para a redução da ocorrência de enchentes. A área de estudo em questão foi Ilha Grande, localizada no litoral sul do Estado do Rio de Janeiro, uma Área de Preservação Permanente que, dentre outras Unidades de Conservação da Natureza, abriga o Parque Estadual de Ilha Grande. Para se analisar a viabilidade de implantação de um telhado verde na região, mais especificamente na Vila Dois Rios (23o11S, 44o12W), foi realizado o levantamento das séries históricas de chuvas da última década na região. Espécies vegetais compatíveis para uso em telhado verde foram encontradas na Ilha e, além disso, foram identificadas as premissas construtivas e operacionais relevantes. Para promover a conscientização dos visitantes e moradores locais foi elaborada uma cartilha informativa ilustrativa. Por fim, concluiu-se que existe a viabilidade de implantação de um telhado verde para captação e aproveitamento das águas das chuvas em Ilha Grande.

O objetivo principal deste trabalho foi identificar os principais fatores abióticos e bióticos correlacionados com a distribuição da abundância e riqueza de hemiepífitos primários, secundários e lianas rizo-escandentes, sinúsias que carecem de estudos, em um gradiente altitudinal na Floresta Atlântica sul-brasileira. Alocamos 15 unidades amostrais no total (de 400 m2 cada), distribuídas nas porções inferior (200 - 250 m a.n.m.), média (380 - 430 m) e superior (670 - 720 m) de um gradiente altitudinal no nordeste do Rio Grande do Sul. Amostramos em cada parcela a abundância de cada espécie, a porcentagem de árvores colonizadas por cada sinúsia e as seguintes variáveis explanatórias: abertura do dossel, composição do solo e densidade de árvores com DAP ≥ 5 e 20 cm; e para cada cota altitudinal, a temperatura e precipitação média anual. Utilizamos modelos lineares generalizados para analisar a influência das variáveis na abundância das sinúsias. Encontramos que as variáveis climáticas (precipitação e temperatura) foram as principais variáveis explanatórias relacionadas com variação na abundância e riqueza das três sinúsias analisadas. As distintas formas de vida apresentaram diferenças na intensidade da resposta às variáveis. Foi registrado um aumento de quatro vezes na abundância de hemiepífitos secundários e de praticamente duas vezes para lianas rizo-escandentes, entre a porção inferior e a superior do gradiente, correlacionando-se positivamente com o aumento da precipitação e umidade. A riqueza total de espécies apresentou um decréscimo na porção superior do gradiente, que foi correlacionado ao decréscimo da temperatura. Os resultados encontrados corroboram trabalhos anteriores, com outros grupos vegetais e animais, que afirmam que as variáveis climáticas são as preditoras de primeira ordem da distribuição das espécies e reforçam a necessidade de se analisar distintas formas de vida, pois estas tendem a responder de modo distinto aos fatores ambientais.
The main aim of this study was to analyze the major abiotic and biotic factors correlated with distribution, abundance and richness of primary and secondary hemiepiphytes and root-climbing lianas along an altitudinal gradient of the South Brazilian Atlantic Forest. Fifteen 400-m² square sample plots within three altitudinal levels at the slope of Serra Geral in north-eastern Rio Grande do Sul were defined. Abundance of all species, the percentage of host trees colonized by each synusia, and explanatory variables canopy openness, soil composition and tree density with DBH ≥ 5 and ≥ 20 cm were recorded for each sample plot. Mean annual air temperature and rainfall were recorded for each altitudinal level. Climatic variables (precipitation and temperature) were the main explanatory variables related with the variation in abundance and richness in the three synusiae studied. The three life forms showed different intensities in their response to these variables. The abundance of secondary hemiepiphytes increased up to four times from the lower to upper altitudinal levels, while root-climbing lianas increased almost twice in the same direction, following an increase in precipitation and humidity. Total species richness decreased toward the upper level of the gradient correlated with lower temperatures and colder winter months. Our results corroborate previous studies on other taxonomic groups, which indicate that climatic variables are first-order predictors for species distribution and reinforce the importance to study different life forms, because these may respond in distinct ways to environment factors.

Twenty years ago, kindergarten was a year of informal education designed to help a child develop some readiness skills, adjust to school, adjust socially and learn through play. Readiness for elementary education was defined in terms of attitude and motivation rather than in specific academic achievements. The hazards of the academic model for young children is supported by recent research. Elkind (1986), for example, confirms that young children do not learn in the same ways as older children and adults. Because the world of things, people, and language is so new to infants and young children, they learn best through direct encounters with their world rather than through formal education. During the '80s there has been an increase in the number of high-risk children entering kindergarten who may not be ready for that experience. Perhaps in response to this trend, kindergarten, rather than serving as a readiness program for future schooling, has become an experience for which children need to be prepared entering kindergarten. The National Association of Early Childhood (1987) notes that expectations have become increasingly high and unrealistic, as the curriculum from upper grades has been pushed down to lower levels, thus doom large numbers of young children to the increased possibility of failure. As a result of this change, there has been quite a controversy over the policy of kindergarten retention. Although grade retention is widely practiced at all levels, research suggests that it does not help children to "catch up." While retained children may appear to do better in the short term, they are at much greater risk for failure than are their non-retained peers (Shepard and Smith, 1990). The provision of an extra year of schooling prior to first grade is intended to protect unprepared children from entering too soon into a demanding academic environment where, 'it is thought, they will almost surely experience failure. Yet Shepard and Smith (1988) note that, "depending on the philosophical basis of kindergarten retention, which differs profoundly from one district to the next, the extra year is meant either to be a time for immature children to grow and develop learning readiness or a time to work on deficient prereading skills" (p. 34). So the criteria by which retention decisions are made are critical. The question of which criteria determine a child's kindergarten retention becomes paramount. The study examines this question by addressing the following issues: 1. Current practices regarding kindergarten retention;2. The percentage of kindergartners retained each year (locally and statewide); 3. The effects of kindergarten retention; 4. The ways in which teacher pressure, parents, standardized tests, and basal reading programs contribute to kindergarten retention; and 5. Alternatives to kindergarten retention. There will always be a group of children who lag behind their kindergarten classmates. Before we create a new program, however, we need to examine the effects of kindergarten retention. It is the intent of this study to provide county school supervisors and others with information which would enable them to take action to reverse the negative effects of past practices. This information can assist those responsible for decision-making as they struggle to make the correct decisions regarding the placement of young children.

The subject of this diploma thesis was to process the study and the design documentation for a newly built hotel in Brno, in city district “Kníničky” near the artificial dam “Přehrada” in a rest area. The hotel will serve as temporary accommodation for up to 64 hotel guests in single, double and four bed rooms. The object also contains training rooms, offices, a meeting room, a café, a small grocery store and a restaurant with kitchen. Parking is possible in one of the two mass garages and there is an outdoor parking possibility in front of the hotel too. The building has a cast-in-place concrete frame with longitudinal beams and sway bracings. The external wall consists of aerated concrete bricks with contact thermal insulation system ETICS (insulation material mineral wool), the ceilings will be cast-in-place reinforced concrete ceilings and the roof flat green roof or flat roof with gravel on it above the 5th floor. The foundation construction consists of reinforced concrete foundation strips, which expand to foundation pads under the load-bearing columns and will be supported by piled foundations under the most exposed elements. As long as the hotel is situated into a fairly steep slope, the vertical alignment of some building parts is various so part of the project is the design of landscaping works. Design documentation was processed using the program AutoCAD 2017, the study and the visualization using both SketchUp 2015, LayOut 2015 and Lumion 5.

The purpose of this study is to examine what pupils in the ninth grade eats for lunch and also whether there is any connection between their lunch habits and perceived ability to concentrate and fatigue. A further aim was to study pupils' experience of dining environment in schools.The study is based on a quantitative method with questionnaires. The study was implemented on four schools in elementary school in themunicipalityofKristianstadand Tanum. Our results demonstrate, in accordance with several previous studies conducted in the same age group, that it is about half of the pupils who eats school lunch every day and that the majority are eating school lunch 3-5 days a week. Furthermore, our study shows that the pupils who rarely eat vegetables in school feel tired and distracted to a greater extent than the group of pupils who eat vegetables almost daily. Our result also shows that the group of pupils who eat the main course 3-5 days a week feel both tired and distracted to a greater extent than the group of students who eat the main course more rarely. In accordance with previous studies our study shows that differences exist between boys and girls regarding food that is eaten instead of school lunch. Food containing empty calories is the most popular kind, it causes glucose levels to get out of balance which makes students tired and distracted.The result of our study shows that most pupils claim that they often feel tired and distracted during the school day. Hunger affects the individual's emotions, motivation and cognition (Lennernäs, 2011), which can be linked to the fact that only 6 % of pupils feel that they are getting satisfied every day after eating the school lunch. There are also many pupils who choose not to eat anything else those days they choose to skip the school lunch. Nevertheless, the majority of pupils are still happy with the environment in the school dining room and it is barely half the pupils who want bigger influence on what is served for school lunch.

The aim of the final thesis is to design and structural design report of selected elements of prefabricated storage hall. Processing of foundation drawing, element composition and for each designed element formwork drawing and reinforcement. It is a single-storey hall, where the main structural system consists of a transversal frame columns and prestressed girder. In this final thesis I designed and structural assessed prestressed girder, reinforced concrete purlin, roof bracing, column, grade beam and foundation pad. The calculation software Scia Engineer is used to calculate the effects of internal forces. The results are compared using a simplified method. The design and structural assessment are made according to valide standards. The designed construction complies with the limit state of ultimate and serviceability.

A captação de água de chuva para o consumo humano por meio de telhados é uma prática crescente, sobretudo em regiões desprovidas de sistemas de abastecimento coletivo, como grande parte do Semi-Árido Brasileiro. Os sistemas de captação de água instalados nessa região se baseiam na construção de cisternas para acumular água captada por meio de telhados. A fim de contribuir para a melhoria do desempenho desses sistemas, este trabalho teve por objetivo estudar os problemas que impedem o bom funcionamento desse importante meio de abastecimento de água e propor soluções projetuais, adotando tecnologia apropriada à população rural do Semi-Árido Brasileiro. Tomou-se como ponto de partida uma pesquisa de campo, realizada na comunidade rural de Paus Brancos, Município de Campina Grande-PB, entre os anos de 2002 e 2003. Os resultados mostraram que 80% das residências pesquisadas dispõem de sistema de captação de água mas que apenas 16% armazenam água suficiente para abastecimento durante todo o ano. Constatou-se que este baixo índice decorre, principalmente, das precárias condições de instalação e manutenção dos subsistemas de condução de água (calhas e dutos). A partir dessa constatação e considerando aspectos funcionais e estético-formais, foram desenvolvidas cinco alternativas de arranjos de sistemas de captação de água de chuva, compostos por telhados, calhas e dutos. Com vistas à simplificação e consequente redução de custos, foram eliminados os suportes das calhas, conferindo ganho de desempenho em relação aos sistemas convencionais. Para testar o desempenho das propostas, foi desenvolvido no Laboratório de Construções Rurais e Ambiência/UFCG um protótipo funcional, em escala reduzida, cuja avaliação revelou que este apresentou excelente desempenho, com eficiência variando de 86% a 92%.
he rooftop rainwater catchment system for the human consumption is an increasing practice, especially in áreas without collective water supply, as in a larger part of the brazilian Semi-arid. The rainwater catchment systems installed in this area are based on construction of cisterns to accumulate water catched by means of roofs. In order to contribute for the improvement of the performance of those systems, this work had the objective of studying the problems that obstacle the good operation of that important way of water supply and to propose projectual solutions, adopting appropriate technology to the rural population of the brazilian Semi-arid. A field research was starting point, accomplished in the rural community of Paus Brancos, in the municipality of Campina Grande -PB, during the period from 2002 to 2003. The results showed that 80% of the researched residences have system of catchment water but only 16% store enough water for provisioning during the whole year. It was verified that this lower index is due, mainly, to the precarious installation conditions and maintenance of the subsystems of water transport (gutters and tubes). Considering this data and functional and aestheticformal aspects, five arrangement alternatives of rainwater catchment systems were developed, composed by roofs, gutters and tubes. Looking for simplification and consequent reduction of costs, the gutters supports of were eliminated, resulting earnings in the performance to comparing conventional systems. To test the performance of the proposed alternative was developed in the Laboratory of Ambience and Rural Construction - LACRA/UFCG a reduced scale functional prototype, whose evaluation revealed an excellent performance, with efficiency ranging from 86% to 92%.

This thesis presents a design of a new building — hotel, containing thirty accommodation units, space for employees, restaurant and vine bar meant for both customers of the hotel, and public. Hotel is situated in a cadastral area Brod nad Dyjí. Building consists of basement and five floors with proposed accommodation capacity of sixty people. The basement perimeter walls are designed from reinforced concrete with the width of 300 and 400 mm. The walls are insulated by XPS polystyrene which is 220 mm wide. Perimeter walls of the above-ground floors are proposed as a combination of reinforced concrete and reinforced skeleton concrete supplemented by masonry wall of therm type. All these constructions are insulated by 220 mm wide glass wool facade insulation. The building envelope is a light ventilated facade. All horizontal constructions are projected as reinforced concrete slabs with the width of 250 mm. The roof of the building consists of three flat parts. The lowest part of the roof is designed as a vegetation roof with extensive layer. The roof of the hotel is proposed as walkable with wear layer made of concrete pavement of dimension 400 x 400 mm. Construction of the roof above the fifth floor is designed as one layer flat roof on concrete slab with the width of 250 mm. Inside the object are three reinforced concrete staircases (main staircase, emergency staircase and staircase for staff). The main entrance to the object is situated on the south side of the property, while the staff entrances are located on the east and north-east part. Parking for the object customers is placed in front of the main entrance, parking for staff is situated on the north side. This thesis is processed in the form of project documentation for construction realisation.

Le developpement des plastes des differents organes vegetaux (racine, hypocotyle et cotyledon), durant la germination des graines, est relie a la transformation des proplastes en amyloplastes dans les racines et en chloroplastes dans les cotyledons. Nous avons analyse durant les sept premiers jours de la germination, l'expression de differents genes nucleaires et plastidiaux codant pour l'appareil traductionnel plastidial ainsi que l'expression de certains genes codant pour l'appareil photosynthetique. Les resultats montrent que les genes nucleaires (rpsl, rps30, rpl21 et rpl40) sont exprimes des les premiers jours de la germination et precede l'expression des genes plastidiaux (photosynthetiques et non photosynthetiques) qui elle commence au troisieme jour. La transcription au promoteur feuille/cotyledon specifique (p1) du gene rpl21 debute aux premieres heures d'imbibition. L'inhibition de la biogenese du chloroplaste par le norflurazon n'affecte pas l'utilisation de ce promoteur p1 suggerant que l'expression de ces genes nucleaires codant pour des proteines plastidiales de menages est independante du signal plastidial

Thesis Theme is a primary school, namely the outbuilding primary school Havlíčkův Brod, Konečná 1884. I suggest first grade pavilion and pavilion with school canteen with kitchens. Pavilions are based on the footings. Pavilions are designed as a two-way system from the wall HELUZ. Construction of ceiling are from ferroconcrete slabs are cross reinforced, single-layer roof is flat with a classic sequence of layers. In addition to construction and process layout I solved also the statics of building in specialize of concrete structures. The following are also evaluated heat and acoustic requirements and requirements for fire safety of buildings. New pavilions are solved as wheelchair accessible. Pavilion of the first grade has two floors with 5 classes of stem, 1 vocational and 2 classes are earmarked for after-school clubs. This pavilion is connected to the connecting neck between the former pavilon A and pavilion B. Dining pavilion has one floor, which is divided in the school canteen and kitchen is connected to the connecting neck leading to the gym. The land is mildly sloping to the south side. All consstructions comply with the applicable standards and recommendations ČSN.
