4. Biology Education and Sustainable Development Sustainable development can be conceived within the concept of growth, advancement, conservation and preservation of the gains of development for the benefit of the present and future. Olorode considered sustainable development as development that meets the needs and aspiration of the present without compromising the ability of future generations to meet their own needs. Nnabuo and Asodike [16]; Olorode stated that, sustainable development is an...

1. Introduction The progress in science and technology during the last few decades has conclusively changed our conception of the significance of various scientific disciplines. The increasing chemicalization of the knowledge is related to the fact that, the progress of learning does not only widens the scope of our knowledge but deepens it and make it more exact. Science education is the field concerned with sharing scientific knowledge, and methods with people not considered part of scientific community...

1. Introduction Numerous chemical insecticides have been used to control some insects. While chemical insecticides have knock down effect, they are too expensive harmfull to both humans and the environment. In addition, target insect pests develop biological resistance rapidly especially at higher rates of application. Thus, the increase in pesticidal application to control this pest has urged to researcher to search for biological control alternatives that would be a good component of Integrated Pest Management...

1. Introduction Algae are plant-like, unicellular or multicellular aquatic organisms. Bioremediation performed by algae is termed phycoremediation. The use of algae to treat wastewater has been in vogue for more than 50 years with one of the first descriptions of this application being reported by Oswald in 1957. Phycoremediation is used to describe remediation of contaminants in a water body using algae (micro and macro algae). It is a branch of bioremediation that makes use of algae. It is a bio-restoration technology involving the use of algae and it is relatively new in Africa...

1. Introduction Particleboard has been defined as generic term for a panel manufactured from linger cellulosic materials, usually wood, primarily in the form of discrete pieces or particles, as distinguished from fibers, combined with a synthetic resin or other suitable binder and bonded together under heat and pressure in a hot press by a process in which the entire interparticle bond is created by the added binder, and to which other materials have been added during manufacture to improve certain properties...

1. Introduction Fish and fisheries products have increasingly remained one of the major foreign exchange earners in Uganda with the sector contributing to total export earnings of 4.9%. The sector employs nearly 500,000 people directly involved in fishing and fish processing. Overall, 1.2 million people depend on the sector for household income. However, this resource is susceptible to depletion due to over-exploitation. Fish farming and management of the fisheries resources can ensure sustainability in the utilization of the fishery resources...

3. Results and Discussion In microwave-fired potato chips fried in corn oil, the acrylamide content ranged between 380 and 12301 ppb. The acrylamide level in potato chips fried at 160°C ranged between 380 and 1040 ppb and was lower than the acrylamide levels detected for frying at other temperatures. In addition, there was degradation of acrylamide with a frying time of 60 s at 180°C, as shown in (Table 2). The same behavior was observed by Amrein et al.; Granda et al.. The acrylamide concentration increased significantly with increasing frying temperature and frying time (P < 0...

2. Materials and Methods 2.2. Microwave Frying Experiments Microwave frying was performed in microwave oven (Panasonics, Model NN-GT353M, Panasonic Asia Pacific, Panasonic Malaysia Sdn Bhd). Three power levels (high at 800 W, medium at 400 W, and low at 200 W) were used to obtain initial frying temperatures of 180±1, 170±1 and 160± 1°C, respectively. The temperatures of the oils inside the microwave cavity were checked with an optical fiber temperature sensor from OPSens. Power levels were determined by an IMPI 2-L test...

1. Introduction In April 2002, the Swedish National Food Administration and the University of Stockholm published data, on the acrylamide content in many foods, such as bread, fried foods, and coffee. Acrylamide is formed during hightemperature processing by the Millard reaction which requires the presence of amino acids, asparagines and reducing sugars, low moisture content. The Swedish National Food Administration reported that fried food products such as chips contain the highest amount of acrylamide...
