Lowering costs for software maintenance, development and reuse is a great challenge. Strategies like the 3 schema architecture for databases has shown to lower maintenance and development costs of databases. For a similar purpose an architecture has been developed over the last 10 years for object-oriented systems. This architecture is now named the COIR architecture and has helped in lowering ...

The purpose of this study was to develop substrates with little or no peat by combining coir-based growing media municipal compost and/or acacia biochar, two locally produced renewable resources, and assess their effects on lettuce seedling emergence growth, as well content in photosynthetic pigments total phenols. Two experiments were carried out, the first six mixes using biochar blended perl...

The electrochemical coating technique was used for the preparation of a polypyrrole coating on a stainless-steel wire, and applied as a fibre for solid phase microextraction (SPME). The polypyrrole fibre was employed for analyzing four volatile aliphatic amines (ethylamine, propylamine, butylamine and pentylamine) in water by headspace SPME using gas chromatography-flame ionization detection (G...

The cellulase producing bacteria was isolated from cow dung and characterized by morphological and biochemical analysis. Further partial purification of cellulase was carried out by dialysis and ammonium phosphate precipitation and also to determine molecular weight by SDS-PAGE. Bacterial isolated were grown on Carboxy Methyl Cellulose (CMC) agar at various optimum conditions such as parameters...

composites provide design flexibility because many of them can be moulded into complex shapes.  carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance with high specific strength and stiffness. these properties led to their numerous advanced applications ranging from military and civil aircraft structures to consumer products. the modelling of beams undergoing arbitrarily ...

Due to increase in the number of goods carrying tricycles, the amount of noise and pollution on our roads has increased. To optimize the control of the engine noise emission for tricycle, different absorptive material liners have been introduced into muffler design. In this study, the performance of Aerogel, Ceramic, Kenaf fibre, Polyester and Rockwool as absorptive material liners on the trans...

Cucumber production has decreased in recent years. Several ways to increase cucumber productivity are the application of organic fertilizers and using appropriate varieties. Coconut coir is one wastes from rest coconut fruit that potential be utilized because it easily obtained large quantities easy process as liquid fertilizer. The aim research was study responses growth yield three (Cucumis s...

Oat (Avena sativa L.) traditionally has been a major crop for feed and forage in Turkey. Theobjective of this research was to study hay yield and quality of oat genotypes harvested at thelate milk stage. One hundred oat varieties of worldwide origin were compared in fieldexperiments in Samsun (northern Turkey) over two growing seasons (2007-2008 and 2008-2009).Significant differences between th...

The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...
