A água de coco é utilizada na cultura popular como substituto da água, e também para repor eletrólitos nos casos de desidratação. Objetivou-se neste trabalho avaliar o processo de armazenamento da água de coco anão verde, produzidas comercialmente e envasadas assepticamente, por indústrias do Sertão Paraibano e do Ceará. Foram coletadas, identificadas, amostras em duas unidades industriais, no dia da sua fabricação, transportadas para o laboratório em caixas isotérmicas com gelo, onde foram analisadas, quanto aos parâmetros físico, físico químicos, microbiológicos e sensoriais, a fim de avaliar a qualidade da água de coco logo após o seu processamento. As amostras obtidas nas indústrias foram armazenadas de acordo com o planejamento fatorial experimental 22 com três repetições do ponto central, para avaliar quantitativamente a influência das variáveis de entrada sobre as respostas, turbidez, condutividade, viscosidade, pH, sólidos solúveis totais, acidez, ácido ascórbico. Constatou-se que a água de coco refrigerada deve ser armazenada a baixas temperaturas, para que sua vida útil possa ser de dez dias. Com o tempo de armazenamento, houve uma diminuição nos valores de pH, vitamina C, condutividade elétrica e sólidos solúveis totais para ambas as indústrias, sendo que os valores de sólidos solúveis totais estão de acordo com o permitido pela legislação, menos para o experimento 4.O pH de todos os experimentos não estão em conformidade com o permitido por legislação, houve aumentos simultâneos para as indústrias quanto aos parâmetros analisados de turbidez, viscosidade, e acidez total titulável, o binômio tempo x temperatura influenciou consideravelmente os parâmetros analisados durante o armazenamento. Microbiologicamente as indústrias não estão em conformidade com o padrão estabelecido pela legislação vigente para coliformes termotolerantes, bolores e leveduras. Não foram encontrados valores para Salmonella sp em nenhuma das amostras analisadas. Sensorialmente a água de coco com 15 dias de armazenamento já se mostrou imprópria para o consumo humano, apresentando características organolépticas alteradas. Sendo indispensável à implantação e monitoramento de Boas Práticas de Fabricação para as indústrias que envasam água de coco. / The Brazil currently has a tendency to increase in cultivation of green dwarf coconut spread virtually throughout the national territory. The coconut water is used in popular culture instead of water, and also to replenish electrolytes in cases of dehydration. The objective of this study was to evaluate the storage process of green dwarf coconut water, commercially produced and bottled aseptically, the Hinterland by Paraiba and Ceará industries. It was collected, identified, samples from two industrial units on the date of its manufacture, transported to the laboratory in cool boxes with ice, where they were analyzed for the physical parameters, chemical, microbiological and sensory physical in order to assess the quality of coconut water after processing. The samples were stored in industries according to the 22 experimental factorial design with three replications of the central point , to quantitatively evaluate the influence of input variables on the responses , turbidity , conductivity, viscosity , pH , total soluble solids , acidity , acid ascorbic . It was found that the chilled coconut water should be stored at low temperatures, so that its life may be ten days. With storage time , there was a decrease in pH , vitamin C , electrical conductivity and total soluble solids for both industries , and the values of soluble solids are in accordance with the permitted except for experiment 4 . the pH of the experiments are not in accordance with the extent permitted by law, there were simultaneous increases in the industries analyzed for parameters of turbidity , viscosity , and total acidity , the binomial time x temperature significantly influenced the parameters analyzed during storage . Microbiologically industries are not in accordance with the standard established by law for fecal coliforms, yeasts and molds. No values for Salmonella were found in any of the samples. Sensory coconut water with 15 days of storage has already proved unfit for human consumption, with altered organoleptic characteristics. Being essential to the implementation and monitoring of Good Manufacturing Practices for industries envasam coconut water.

Master’s thesis on Energy performance of domestic hot water preparation is concerned with calculating and comparing the energy performance of domestic hot water preparation in two-generation family house with an administrative part. Energy performance of domestic hot water preparation is calculated by two calculation methods and by experimental measurements, which are compared at the end of the thesis. The calculation is performed according to standard ČSN 06 0320 and set of standards ČSN EN 15316-3. Thesis is processed in accordance with valid legislative regulations.

This thesis is developed as a proposal for heating for a primary school and kindergarten in the region of Brno-countryside. For the insulated building, a combination of heating and air-conditioning is proposed. The concept is designed so that the air-conditioning preheats the exterior air and the heating system warms the incoming air to a comfortable temperature. For the required thermal performance, sources of heat (for gas and pellets) and a layout solution for the boiler room is designed. Drainage of combustion products is proposed for both solutions. The project solution is per the extent of the construction permit. The theoretical part is linked with the practical part through the condensation boilers, their function and division, and drainage of combustion products. The experiment for the given topic was conducted on the drainage of combustion products. The pressure loss of the reverse knob was determined in relation to the flow rate of air in the condensation boilers as this loss is essential in assessing the drainage of combustion products.

This research focused on evaluating and comparing the perceptions, water-use behaviour, water conservation awareness and overall water stewardship of participants residing in Hammanskraal and Atteridgeville who have experienced intermittent water supply in their domestic households – due to either water contamination incidents caused by dilapidated infrastructure or water restrictions implemented by the City of Tshwane Metropolitan Municipality during the 2016–2017 drought in the Gauteng Province. The research concluded that the municipality needs to implement proactive water conservation awareness initiatives on an ongoing basis to reduce high water demands and to create a culture of water stewardship, especially in Atteridgeville. Transparent communication is also required from the municipality to instil the necessary trust among the public. It is recommended that the municipality attends to water leaks and ongoing complaints from the public timeously to reduce the current apathy from the public against reporting water-related issues and to ultimately ensure compliance to water restrictions. / Hierdie navorsing fokus op die evaluering en vergelyking van deelnemers wat in Hammanskraal en Atteridgeville woon se persepsies, waterverbruiksgedrag, waterbewaringsbewustheid en algehele waterrentmeesterskap, wat onderbroke watervoorsiening in hulle huishoudings ervaar het – as gevolg van waterbesoedelingsvoorvalle wat deur vervalle infrastruktuur veroorsaak is en waterbeperkings wat deur die Stad Tshwane Metropolitaanse Munisipaliteit gedurende die 2016 tot 2017-droogte in Gauteng ingestel is. Die navorsing het tot die gevolgtrekking gekom dat die munisipaliteit proaktiewe waterbewaringsbewustheidsinisiatiewe op ’n deurlopende grondslag moet implementeer om hoë wateraanvraag te verminder en ’n kultuur van waterrentmeesterskap, veral in Atteridgeville, te skep. Deursigtige kommunikasie word ook van die munisipaliteit vereis om die nodige vertroue by die publiek te kweek. Daar word aanbeveel dat die munisipaliteit betyds aandag aan waterlekkasies en deurlopende klagtes van die publiek sal gee om die huidige onverskilligheid van die publiek by die aanmeld van waterverwante aangeleenthede te verminder en om uiteindelik te verseker dat die publiek die waterbeperkings eerbiedig. / Patlisiso ena e ne e tsepame hodima ho lekola le ho bapisa maikutlo, boitshwaro ba tshebediso ya metsi, tsebo ka poloko ya metsi le tlhokomelo e akaretsang ya metsi ke bankakarolo ba dulang Hammanskraal le Atteridgeville ba bileng le phepelo ya metsi e kgaohang malapeng a bona – e ka ba ka lebaka la diketsahalo tsa tshilafatso ya metsi e bakilweng ke dipeipi tse senyehileng kapa ho kgaolwa ha metsi ho kentsweng tshebetsong ke Masepala wa Motsemoholo wa Metropolitan wa Tshwane nakong ya komello ya 2016–2017 porofenseng ya Gauteng.
