Role of Application Service Providers in Infrastructure Development for Web-enabled Course Administration Tool

For the effective teaching, the teacher must monitor the effectiveness and performance of the teaching methodology and techniques. For this purpose teacher can use various tools. The effective teaching can be achieved by using different elements of teaching. This paper proposes a system tools called OCAT-PA – Online Course Administration tool for Performance Analysis. This tool can be implemented as standalone system, client-server system or web enabled system. This paper focuses on the web-enabled implementation of the tool. It also focuses on the involvement of the Application Service Providers. This paper discusses the role of application service providers in the proposed system with benefits

Business Model for Developing the Courseware for e-Learning and Self Paced Learning of Programming Languages

Teaching and learning programming language is a challenging task at the undergraduate level. This paper focuses on the basic elements required in learning the programming languages at undergraduate level. In this paper authors share their experience of the development of course material using the multimedia tools. They found that it is difficult to maintain the system, as it requires constant development. They propose a component model in the continuing development of such multimedia courseware incorporating the industry with a business model to support this development

Amylopectin grafted with poly (acrylic acid): Development and application of a high performance flocculant

In recent years, wastewater treatment, especially for wastewaters which are not suitably recycled by conventional or normal biological processes, is getting more importance. Of late, natural biopolymer based flocculants are extensively used for wastewater treatment because of low cost, environment-friendly and easily availablility from reproducible farm and forest resources. This article introduces the development of a natural polymer based flocculant [amylopectin grafted with poly (acrylic acid) - AP-g-PAA] for treatment of synthetic effluent as well as mining industry wastewater. The graft copolymer based flocculants have been developed under optimum conditions and characterized using viscometry, C-13 NMR, SEM, TGA, rheological characteristics, determination of hydrodynamic radius and CHN analysis. The flocculation characteristics of grafted and ungrafted polysaccharide have been evaluated in synthetic effluents (as Fe-ore, kaolin, Mn ore suspensions) as well as in mining industry wastewater.

Transcriptional Activation of OsDERF1 in OsERF3 and OsAP2-39 Negatively Modulates Ethylene Synthesis and Drought Tolerance in Rice

The phytohormone ethylene is a key signaling molecule that regulates a variety of developmental processes and stress responses in plants. Transcriptional modulation is a pivotal process controlling ethylene synthesis, which further triggers the expression of stress-related genes and plant adaptation to stresses; however, it is unclear how this process is transcriptionally modulated in rice. In the present research, we report the transcriptional regulation of a novel rice ethylene response factor (ERF) in ethylene synthesis and drought tolerance. Through analysis of transcriptional data, one of the drought-responsive ERF genes, OsDERF1, was identified for its activation in response to drought, ethylene and abscisic acid. Transgenic plants overexpressing OsDERF1 (OE) led to reduced tolerance to drought stress in rice at seedling stage, while knockdown of OsDERF1 (RI) expression conferred enhanced tolerance at seedling and tillering stages. This regulation was supported by negative modulation in osmotic adjustment response. To elucidate the molecular basis of drought tolerance, we identified the target genes of OsDERF1 using the Affymetrix GeneChip, including the activation of cluster stress-related negative regulators such as ERF repressors. Biochemical and molecular approaches showed that OsDERF1 at least directly interacted with the GCC box in the promoters of ERF repressors OsERF3 and OsAP2-39. Further investigations showed that OE seedlings had reduced expression (while RI lines showed enhanced expression) of ethylene synthesis genes, thereby resulting in changes in ethylene production. Moreover, overexpression of OsERF3/OsAP2-39 suppressed ethylene synthesis. In addition, application of ACC recovered the drought-sensitive phenotype in the lines overexpressing OsERF3, showing that ethylene production contributed to drought response in rice. Thus our data reveal that a novel ERF transcriptional cascade modulates drought response through controlling the ethylene synthesis, deepening our understanding of the regulation of ERF proteins in ethylene related drought response

Bio-desulphurization of makum (Assam) coal

In the present study an attempt has been made to carry out investigation on bio-desulphurization of high sulphur coal. For this purpose, coal containing high sulphur has been obtained from Makum area of Assam. Initially, the samples received were subjected for detailed characterization studies including proximate and ultimate analysis to ascertain various constituents such as C, H, N, S, ash percentage and moisture content etc. Further, the experiments were carried out to study the desulphurization using a bioreactor for a period of 15 days at 32°C with initial pH 2.5 in presence of thermophilic microbes. During the studies different parameter such as variation of pH, reduction of sulphur, ash and nitrogen were analysed. From the studies it was possible to reduce 53.64% Ash, 42.15% Nitrogen and 8.62% Sulphur over a period of 15 days

Enabling Design

Designed to meet the diverse needs of therapists, this book presents a new approach to rehabilitation that integrates ergonomics concepts to address the wide range of problems commonly encountered by professionals. The first section addresses general concepts such as anthropometry and tissue mechanics. The next section explores whole body biomechanics, demonstrating the ergonomic effects of physiological and biomechanical factors. The third section focuses on regional biomechanics, explaining the rationale for ergonomic intervention. The final section of the text offers with a detailed discussion of the ergonomic paradigm in rehabilitation, including the use of physical demands analysis

An Archaeology of Ireland's Border

The reutilization of biomass ashes in agriculture is important to create nutrient cycles. In field and pot experiments we investigated the fertilizing effects of different biomass ashes for eight different crops on a loamy sand and sandy loam. Special emphasis was given to phosphours(P). The ashes showed large differences in their elemental composition
