The modern computerised era in which we live means that all areas of society are subjected to information technology. Children are increasingly exposed to and have access to computers, which necessarily have an influence on their education and development. Seeing that children are the most receptive group when it comes to exposure to new technology, this may have enriching effects on computer literacy, which is often considered part of general literacy. With regards to literacy, reading is one of the skills which pose a high challenge. It is also a key skill that opens the world of information, as most information is received through reading. Any reading stimulation via electronic or printed media that encourages learners to read is considered to improve reading ability, reading speed, reading comprehension and phonetic awareness. The aim of this study was to determine whether there was a correlation between early computer exposure and experience (both computer access and use) and reading ability of grade 1 learners. In this study a one shot cross-sectional survey design was used. Schools with grade 1 learners in the Umvoti district of Kwa Zulu Natal were selected to participate in the study - stratified sampling was used. The grade 1 classes were selected on the basis of random sampling. The selected classes (N=4; 85 learners) participated 'intact' in the study. The data was analysed using descriptive as well as inferential statistics (e.g. MANCOVA). / Thesis (M.Ed.)--North-West University, Potchefstroom Campus, 2007.

The concept of function is crucial to a great extent in modern mathematics and is considered a major barrier to many mathematics students. Students have difficulty interpreting information related to functions in general, and quadratic functions in particular. Quadratic Function is one of the topics which are covered in a course which is compulsory for a large number of students in the General Education Program of Zayed University. This program leads to different majors, including Mathematics Education, Business, Information Technology, and other majors. The challenge in teaching Quadratic Function in a course like this is mostly based on the fact that many students think that Quadratic Function is a difficult topic to understand and learn, and some teachers would agree with them that it is difficult to teach. In this paper, I demonstrate real world problems aimed to improve the students understanding of Quadratic Functions; life problems on this topic support developing student’s knowledge, critical thinking, quantitative reasoning, and analytical skills. This paper also includes examples of the techniques used with graphing of quadratic function, the algebra, and inverses of the same function. International move to improve mathematics curriculum have supported new goals for student’s learning which highlights problem solving skills, reasoning, ability to work in groups and individually, and use of technology. Knowing that information technology plays considerable role in achieving the above goals, teaching students the concept of Quadratic Functions can be smoothly achieved by using Information Technology in solving real world problems.

The thesis addresses the issue of use and abuse of drugs in individual types of secondary schools in the district of Teplice and their mutual comparison. The theoretical part describes the issue of drug and other than drug addictions and their impacts on the target population of the secondary-school youth. It also describes individual drugs in respect of their effects and risks of intoxication, protective factors and risk situations. The research was conducted in secondary schools in the district of Teplice. The comparison involved a secondary vocational school, a secondary technical school ended with the final school-leaving examination and a grammar school. The first hypothesis assumes that most of students attending secondary schools have experience in respect of drugs. The second hypothesis assumes that drugs are taken for the first time before reaching the fifteenth year of age. The third hypothesis assumes that the drug most widespread among students is marihuana. The last hypothesis assumes that the minimum of three per cent of students have experience in sniffing of volatile substances.

1 Resumé The topic of this diploma thesis is Rent and Other Payments for (Using of) Residential Space in the current Czech legal regulation and the subsequent comparison with the German and Slovak legislation. The introduction to rent in the Czech Republic, which includes a brief historical development, is followed by a detailed analysis of the provision on rent and other payments for (using of) residential space while a substantial part of the work is concerned with increases in rent. Moreover, the thesis contains an analysis of German and Slovak legislation on rent, focusing on the similarities and differences as compared to Czech legislation. The current Czech Civil Code is based on the principle of private autonomy, but even it has its limits, that are obvious in leases for residential space legislation. The Civil Code contains a number of mandatory standards from which it is not possible to validly derogate to disadvantage of the lessee. However, these special provisions may be applied only in the case that the lease serves to satisfy the lessee's or his household members' housing needs. One of the lessee's principal obligations is to pay the rent, which is negotiated as a fixed amount payed usually per month, but the parties are allowed to arrange another payment period. Furthermore, it is...

Differents drafts of tooth implant insert differents levels of tension in the surrounding bones. This can results in differents prognostics for the implants installed. This work considered by photoelasticity (resilience) of the circuit transmission the gradient of tensions produced in near pre-ordered of the implants when installed in photoelasticity matrix. Eight points were considered when no burden and thirteen points when submited to the axial burden of 0,30N, testing the hypothesis that the tension is the same at the differents implants. The implants used were Titamax TI Medular, Titamax TI Cortical, Titamax Cone Morse and Alvim TI (Neodent, Curitiba, Brazil). The value of the midle cutting tension between the analysed points of each group was submited to the variant analyse showing that has a suggestive statistic difference (p<0,05) between the unburden group. In this situation the Tukey test showed where the difference was. The results outpointed that between the tested implants, the one that produced more medium tension after the installation was the Alvim TI and the axial burden incidence did not result in significative difference at the medium tension produced for all the groups. This work objective was to estimate, in photoelasticity analyse, the tension produced by differents drafts of implants after their installation and after burden incidence, testing the hypothesis that the tension is the same in the differents kinds of implants. / Diferentes desenhos de implantes dentários introduzem diferentes níveis de tensão no osso circundante, podendo resultar diferentes prognósticos para os implantes instalados. Este trabalho avaliou por meio da fotoelasticidade de transmissão circular os gradientes de tensões gerados em pontos prédeterminados próximos aos implantes quando instalados em matrizes fotoelásticas. Foram avaliados oito pontos quando sem carga e 13 pontos quando submetidos ao carregamento axial de 0,30N, testando à hipótese de que a tensão é a mesma nos diferentes tipos de implantes. Foram utilizados os implantes Titamax TI Medular, Titamax TI Cortical, Titamax Cone Morse e Alvim TI (Neodent, Curitiba, Brasil). O valor da tensão cisalhante média entre os pontos analisados de cada grupo foi submetido à análise de variância, demonstrando que houve diferença estatisticamente significante (p<0,05) entre os grupos sem carga. Nessa situação o teste de Tukey demonstrou onde estava a diferença. Os resultados indicaram que entre os implantes testados, o que gerou maior tensão média após a instalação foi o Alvim TI e que a incidência de carga axial não resultou em diferença significativa nas tensões médias geradas para todos os grupos. O objetivo deste trabalho foi avaliar, por meio de análise fotoelástica, a tensão gerada por implantes de diferentes desenhos após sua instalação e após a aplicação de carga, testando à hipótese de que a tensão é a mesma nos diferentes tipos de implantes. / Mestre em Odontologia

O presente trabalho teve como objetivo o estudo da potencialidade de aplicação da flotação por ar dissolvido (FAD) lamelar (de alta taxa) e convencional como parte final de sistema de tratamento sequencial de esgoto sanitário, constituído de reatores anaeróbios de manta de lodo (UASB) seguidos de tanque de aeração. O trabalho, desenvolvido na Estação de Tratamento de Esgotos Jardim das Flores da cidade de Rio Claro, foi dividido em três etapas. Na primeira etapa, realizada com equipamento Flotateste, foram investigados os valores mais adequados de dosagens de polímero sintético catiônico, amido de araruta, cloreto férrico e associações entre cloreto férrico e polímero ou amido de araruta, de razão ar/sólidos (A/S), bem como de tempo e gradiente de mistura rápida e de floculação. Nessa etapa, os melhores desempenhos da FAD foram obtidos com o emprego de polímero catiônico, tanto isoladamente quanto associado ao cloreto férrico, sendo esta última condição imprescindível para maior remoção de fósforo. A flotação de liquor misto utilizando apenas o cloreto férrico como coagulante, apresentou desempenho extremamente insatisfatório, com a formação de flocos com características ruins de flotabilidade. Além disso, observou-se que a flotação desse tipo de efluente requisitou condições mais amenas de mistura, sendo que, em muitos casos, os melhores resultados foram obtidos mediante a eliminação da mistura rápida ou da floculação. Nas segunda e terceira etapas, realizadas com unidades piloto de flotação lamelar de alta taxa (FADAT) e convencional, respectivamente, e empregando apenas polímero como auxiliar de floculação/flotação (dosagem em torno de 1 g de polímero/kg de SST), foram investigados os valores mais adequados de Taxa de Aplicação Superficial (TAS), Taxa de Aplicação de Sólidos (TS) e quantidade de ar fornecida à flotação, calculada através da razão A/S ou da dosagem de ar (Dar), em g de ar/'M POT.3' de esgoto afluente, dependendo da concentração de sólidos suspensos totais afluentes à flotação (SSTafl). Através dos resultados dos ensaios pôde-se observar que a razão A/S é mais adequada para o cálculo da quantidade de ar na flotação de suspensões concentradas (SSTafl acima de 1100 mg/L no presente estudo), ao passo que Dar é mais representativo no caso da flotação de suspensões diluídas. Empregando a unidade FADAT, alimentada com liquor misto de tanque de aeração em boas condições de biofloculação, foi possível obter resultados satisfatórios para TAS de até 350 'M POT.3'/'M POT.2'.dia e TS entre 120 e 250 kg de SST/'M POT.2'.dia, desde que fornecida quantidade adequada de ar ao processo (Dar na faixa de 15,0 a 18,0 g de ar/'M POT.3' de afluente), para SSTafl entre 800 e 1100 mg/L. Na flotação lamelar de alta taxa, constatou-se que o bom desempenho esteve diretamente relacionado a baixos valores de SSTafl. As recomendações para a flotação com unidade de FAD convencional tiveram que ser mais conservadoras, devido às condições ruins de biofloculação apresentadas pelo liquor misto do tanque de aeração durante a realização da terceira etapa do trabalho. Nesses ensaios, os resultados mais satisfatórios foram obtidos com o emprego de TAS em torno de 200 'M POT.3'/'M POT.2'.dia, TS menor que 200 kg de SST/'M POT.2'.dia e A/S em torno de 0,020 (Dar de 21,0 g de ar/'M POT.3' de afluente), para SSTafl em torno de 1400 mg/L / The aim of this research was the study of the lamella design (high rate) and conventional dissolved air flotation (DAF) process potentiality of application as the final part of a domestic sewage sequential treatment system made up anaerobic reactors (UASB) followed by aeration tank. The work, developed at the Jardim das Flores WWTP of Rio Claro city, was separated in three phases. In the first phase, using the flotatest apparatus, the most suitable values of chemical (synthetic cationic polymer, arrow-root starch, ferric chloride and ferric chloride combined with polymer or arrow-root starch) dosages, air to solids ratio (A/S), as well as rapid mix and flocculation time and mean velocity gradient values, were investigated. In this phase, the best DAF performances were obtained with the application of cationic polymer, alone and associated to ferric chloride. The use of ferric chloride was essential to obtain better phosphorus removal results. The mixed liquor flotation using ferric chloride alone as primary coagulant presented extremely unsatisfactory performance, with the formation of flocks showing bad characteristics of flotability. Moreover, it was observed that flotation of this kind of effluent had requested gentler mixture conditions. In many cases, the best results were obtained by means of rapid mix or flocculation step elimination. In the second and third phases, using the lamella design and conventional flotation units respectively and cationic polymer as the only flocculation/flotation aid (dosage around 1 g of polymer/kg TSS), the most suitable values of Overflow Rate (OR), Solids Application Rate (SAR) and amount of air supplied to the flotation process, expressed as the A/S ratio or air dosage (AD, in g of air/'M POT.3' of influent) depending on influent total suspended solids concentration (TSSinfl), were investigated. The flotation essays results showed that the A/S ratio is more suitable for the air supply estimation in flotation of concentrated suspensions (TSSinfl above 1100 mg/L in this study). Contrarily, the parameter AD is more representative in cases of flotation of diluted suspensions. Using the lamella design unit, fed with aeration tank mixed liquor presenting good bio-flocculation conditions, it was possible to obtain adequate results applying OR as high as 350 'M POT.3'/('M POT.2'.day) combined with SAR values between 120 and 250 kg of TSS/('M POT.2'.day), since the adequate amount of air has been provided for the process (AD values between 15,0 and 18,0 g of air/'M POT.3' of influent), for TSSinfl between 800 and 1100 mg/L. For the lamella flotation, it was noticed that the best performance has been directly associated to lower values of TSSinfl. The recommendations for flotation using the conventional DAF unit had to be more conservative, taking into account the poor bio-flocculation conditions presented by the mixed liquor during the third phase of work. In theses essays, the more adequate results were obtained by applying OR around 200 'M POT.3'/('M POT.2'.day), SAR under 200 kg of TSS/('M POT.2'.day) and A/S ratio around 0,020 (AD of 21,0 g of air/'M POT.3' of influent), for TSSinfl around 1400 mg/L

Today, there are many high-level interactive applications and products around the world which are developed by using programming languages or software. Basically, games, virtual museums, educational applications, interactive architectural products are the simplest examples about these interactive solutions. In this thesis, interactive gallery means moving objects in a three-dimensional room. Objects can be re-placed by using keyboard keys in this three-dimensional room. Thus, user can move these interactive objects in accordance with intended purpose. Interactive gallery is similar with a room that has furniture, door and windows. Also, this room includes interactive objects in it. The main focal point is about how these objects can be displayed interactively and how different methods are used, when these processes are started to be made. This thesis helps to solve these questions. Interactive gallery bases on model loading structure and on the following thesis, this process is parted. It starts with 3D modelling, continuous with model loading and it ends with key implementation.
