This study is an exploratory and descriptive study of shopping malls in two cultures. The purpose of this dissertation is twofold: (1) to explore and describe the conditions of malls relevant to people’s perception of space and their interactions with others; and (2) to investig…
Short-horned grasshoppers (Orthoptera: Acrididae) were studied in the field as well as in laboratory for their distribution, identification, preferred food plants and feeding damage. These grasshoppers compete for forage with cattle. Examination of the 20 most common grasshopper…
In the past fifty years, a need to address the ethical and social dimensions in the biosciences has become pervasive. To this end, notions of bioethics, and an associated range of methodologies have been institutionalised throughout the UK biosciences; talk of research ethics, p…
Microalgae are a diverse group of oxygenic photosynthetic microorganisms which show great promise as a source of biofuel. However, significant challenges still remain before microalgae can be considered a viable source of biofuel. The main current challenges are nutrient sourcin…
Malaysia's transportation sector accounts for 48% of the country's total energy use. The country is expected to become a net oil importer by the year 2011. To encourage renewable energy development and relieve the country's emerging oil dependence, in 2006 the government mandate…
Due to the increasing awareness of the dwindling fossil fuel resources and environmental issues, biofuel became an alternative renewable fuel to meet the steady increase of energy consumption and environmental demands. This work was designed to produce biofuel free from glycerol…
Globally over 3 billion people use solid fuel cookstoves to meet household energy demand. Cookstove emissions lead to household and ambient air pollution, with adverse health and climate impacts. To reduce these harmful impacts, alternative cookstove technologies have been devel…
Congress passed the Energy Policy Act of 2005 and the Energy Independence and Security Act (EISA) of 2007 to reduce dependency on foreign oil by increasing the use of biofuels. EISA mandates 36 billion gallons of biofuel production in 2022, representing an increase of 118% in ei…
Biomass, being the only renewable source of carbon, has the potential to serve as a sustainable platform for the production of energy and chemicals, in this era of diminishing supplies of fossil fuels. The conversion of lignocellulose to fuels and chemicals requires the effectiv…
