3. Indoor Air Quality in the Hospital: The Influence of Heating, Ventilating and Conditioning Systems
Abstract Clean, fresh air is the most important requirement for good indoor air quality (IAQ) in all buildings, but it is especially important with regard to the environments within hospitals and other healthcare facilities. The literature indicates that buildings with heating, ventilating and air conditioning (HVAC) systems may have an increased risk of sic

4. Replacement of fish meal by protein soybean concentrate in practical diets for Pacific white shrimp
ABSTRACTThe objective of this work was to evaluate the performance of Litopenaeus vannameifed different levels (0, 25, 50, 75, and 100%) of soybean protein concentrate (63.07% crude protein, CP) to replace fish meal-by product (61.24% CP). The study was conducted in clear water in fifteen 800 L tanks equipped with aeration systems, constant heating (29 ºC),

7. Usuários de habitação de interesse social e adoção de sistemas de aquecimento solar de água - estudo de caso em Londrina-PR
This research is dedicated to investigate the reasons why the solar water heating systems are not used in large scale on low-income housing in Brazil. There is a global tendency to reduce dependence on fossil energy resources, however, the influence and economic ruling of oligopolies that holds the end-use traditional energy costs demonstrate the vulnerabili

8. Desempenho energético e caracterização dos sistemas de aquecimento de água de piscinas. / Energetic performance and characterization of swimming pool heating systems.
The aim of this research is to investigate the energetic performance of two distinct kinds of swimming pool heating systems: gas-fired and electric heat pump. A practical instrumentation research was prepared in these two indoor swimming pools, placed in the same location. Besides these, other four swimming pool, placed each in a different ambient in the cit

12. Controlador fuzzy para otimização de sistemas de aquecimento de agua com coletores solares / Fyzzy controller for optimization of water heating systems with solar collectors
Although significant savings in electrical energy are achieved with commercially available solar water heaters, they do not present a good performance in days that the radiation is not good, because the boiler is filled with cold water whenever the hot water is used. In this work, a new solar heating system, which minimizes the use of electrical energy, is p
