Symbolism in Coptic Architecture: The Power of ‘Meaning’ in Architectural Expression
Abstract: New trends in architecture tend to pursue to duplicate the positive, pleasant effects of historical buildings, away from direct copying from their form or their style. By addressing human cognition to try to decode their meanings, symbols, which were traditionally seen as a sacred language, were used in religious buildings to establish a visual discourse with the worshipers. This paper aims at analyzing the patterns symbolic language in Coptic architecture, …

Assessing Accessibility in Residential Neighbourhoods of Colonial Towns: Case of Little Europe, West Bengal, India
Abstract: Bengal has a strong connection with the history of colonization in the Indian subcontinent. It was witness to commercial forays by East India Companies (EIC) set up by a number of European powers. The four colonial towns of Serampore, Chandernagore, Chinsurah and Bandel set up by the Dutch, French, Danes and Portuguese EICs have recently been designated as “Little Europe” by the Government of West Bengal. These towns, representing the …

Bacterial Diversity of Decomposing Leaf Litters of Polyalthia longifolia (Sonner.) Thw. and Rhododendron arboreum Sm. Under Natural Condition
Abstract: The role of microorganisms in the decomposition of plant material is of immense importance. A large amount of plant litter is added annually to the soil through leaf fall and death of plants. As the plant materials fall on the ground, they are immediately attacked by various groups of soil microorganisms and soon after, the process of decomposition is initiated. Microorganisms being heterotrophic in their mode of nutrition are responsible …

Desizing of Cotton Fabrics With Enzymes for Improved Performance
Abstract: Desizing of cotton substrates with Amylase enzymes has been practiced since long time and is commercially successful. Amylases convert the water insoluble starches, used during sizing operation for enhancing the performance of the warp yarns, into water soluble products which are removed during subsequent washing. The use of enzymes for desizing is quite safe for the cotton substrates and do not cause any detrimental effect on the cotton cellulose unlike …
