A large part of the environmental impact of animal production systems is due to the production of feed. Insects are suggested to efficiently convert feed to body mass and might therefore form a more sustainable food and/or feed source. Four diets were composed from by-products of food manufacturing and formulated such as to vary in protein and fat content. These were offered to newly hatched Ar...

A study was carried out to identify and estimate the prevalence of ecto- and endoparasites of village chicken between April and July 2008 in three local councils of Enugu state, Nigeria. A total of 1038 chickens comprising of 468 chicks, 207 growers and 363 adults were examined during the house to house survey for ectoparasites, gastrointestinal helminths and coccidia infections. Our finding sh...

The production of cement results in emission of many green house gases in atmosphere, which are responsible for global warming. Hence, the researchers are currently focused on use of waste material having cementing properties, which can be added in concrete as partial replacement of cement, without compromising on its strength and durability, which will result in decrease of cement production t...

An ecological pilot project for the control of Triatoma dimidiata allowed a new evaluation four and five years after environmental modifications in the peridomestic areas of 20 households. It was verified that the two groups of houses, 10 case-houses and 10 control-houses, were free of insects after those periods of time. In the first group, the owners started a chicken coop in the backyard and...

Global threats of fuel shortages in the near future and climate change due to green-house gas emissions are posing serious challenges and hence it is imperative to explore means for sustainable ways of prevention the consequences. The huge need for sustainable energy has led to an increased interest in new energy resources, such as production of microalgae, for use as biofuel and its other appl...

To date, almost all of the research on green/sustainable energy has been concerned with procurement of ever increasing amounts of energy for human consumption. This singular focus only on the supply-side of the problem completely overlooks what happens to the energy after we use it; thereby implicitly making the dangerously wrong assumption that the earth has unlimited capacity to dissipate ene...

1. Sustainable development Today, the concept of sustainability significantly affects our life and economic activities. In 1987, the Bruntland Commission stated: “Humanity has the possibility of making development sustainable, i.e. ensuring that the needs of the present are met without compromising the ability of future generations to meet their own needs” (World Commission for environment and ...

Chagas disease is caused by Trypanosoma cruzi, which is mainly transmitted by the faeces of triatomine insects that find favourable environments in poorly constructed houses. Previous studies have documented persistent triatomine infestation in houses in the province of Loja in southern Ecuador despite repeated insecticide and educational interventions. We aim to develop a sustainable strategy ...

Electricity is essential for all households irrespective of their geographical location. Its demand is increasing day by day due to the rapid population growth and greater use of electricity for better standard of living. As the conventional sources of energy are shrinking, a need has arisen to look for alternative sources of energy with more emphasis on its optimal use. This paper presents des...

this study evaluates the lifelikeness layers of boroujerdi’s house in kashan as a case study to analyze the houses of islamic period, especially qajar era. why traditional iranian architecture was considered as sustainable architecture? what are the elements included in the traditional architecture to take the most advantage of the least facilities? what elements does the modern architecture la...
