Motivational level towards the use of ICT among level 2 primary school pupils

The use of Information and Communication Technologies (ICT) is steadily integrated into teaching and learning process. Therefore pupils' exposure and opportunities in using ICT in learning has become an important factor. The purpose of this research is to investigate the level of motivation towards the use of ICT among ESL learners in primary school level. Thus A group of 70 level two (year 4, 5 and 6) pupils of a suburban primary school in Alor Gajah, Melaka were chosen as respondents for this research. The research adopted quantitative methods to find out the motivational level of pupils in learning the English Language towards the use of ICT in the 21st century learning. Finding showed that the ESL pupils are motivated to use ICT in learning where in specific of this research, the level of motivation among female pupils are higher than male pupils. In conclusion, it is good if educators could find a way to be more competence in integration of ICT in teaching and learning process based on what barriers teachers are facing in using ICT in their daily classrooms in schools.

Isolation, partial purification and characterization of Lectin protein from soybean seeds (Glycine Max) and its cytotoxicity against Hela Cells

Plant lectin proteins have a wide range of biological importance. In this research work the isolation,partial purification and characterization of the lectin proteins from the Soybean seeds (Glycine max) have been reported. The lectin proteins was purified with the help of ion exchange chromatography and further gel filtration chromatography on DEAE Cellulose column and Sephadex G-100 column respectively. Human blood group A was used for the agglutination assay. Lectin Protein concentration was determined by Lowry method and further analysis was done by SDS- PAGE. Samples were dialysed against phosphate buffer saline (PBS) and SDS-PAGE was done to identify the molecular weight of fractions. Further, haemagglutination assay was performed for sample of crude, 20% cut, 60% cut, 90% cut, dialysed samples, 60% ion exchange chromatography portion using A type blood group. The highest titer value was obtained from agglutination assay the sample from gel filtration chromatography i.e.512HU and the specific activity is 6400 HU/mg. The partially purified lectin protein gave a single protein peak on ion exchange chromatography. On SDS-PAGE electrophoretogram, many bands were observed, out of which one band was of 30 kDa which is supposed to be the band of lectin. The partially purified lectin show cytotoxic activity against HeLa cell line. The highest inhibition of HeLa cells i.e. 63.8% was observed at the concentration of 250μg/ml. Thus, the IC50 of partially purified lectin protein was found to be 99.2μl/ml.

Study of domestic refrigerator system with R-134a and blends of HC R290/600a

In domestic refrigerators and refrigeration systems, the most widely used refrigerant is R134a. It must be phased out soon according to Kyoto protocol due to its high Global Warming Potential (GWP) of 1300. Hydrocarbon mixture (HCM) is an alternative refrigerant for Hydro Fluorocarbon (HFC) and Chlorofluorocarbon (CFC) compounds due to their lower GWP and zero Ozone Depletion Potential (ODP). The impact on the environment is also reduced due to the usage of hydrocarbon mixture in different mass ratios. In the present work, an experimental investigation has been made with a hydrocarbon refrigerant mixture composed of R290 (Propane) and R600a (Isobutane) as an alternative to R134a in a single evaporator domestic refrigerator. The primary object of the proposed work is to evaluate the performance parameters like compressor power consumption, Discharge temperature, Refrigeration effect, Coefficient of performance (COP), cycle efficiency and Ton of Refrigeration with an optimized mixture of R290 and R600a refrigerant and compare it with the performance of R 134a refrigerant. The investigation aims to find out the optimized blending mixture of R290 and R600a refrigerant and validate it towards REFPROP software. The hermetically sealed compressor (Capacity 1/4 T) to be used to analyze the performance of the refrigeration cycle. From the comparative analysis of both refrigerants, it was found that hydrocarbon blend of R-290 and R-600a in 30%-70% on a mass basis given a better performance than R-134a refrigerant.

Performance analysis of Vigilance Control Device (VCD) In electric locomotives of Indian Railways and design of a Drowsiness Detection and Warning system

A Vigilance control device (VCD) is a safety device designed and installed in Electric locomotive to keep the loco pilots in the vigilant state. These devices are available in all the Electric locomotives in Indian railways since the year 2003. Having served more than 15 years in the locomotive, the performance of the VCD in keeping the loco pilots is critically analyzed. Further, it is proposed the design of an embedded system that will function as an intelligent drowsiness detection and warning system. This proposed system will replace the existing Vigilance control device of the locomotive with additional and essential features of detection of drowsiness in early-stage and alert the Crew of the Train operation. The system will have advantages over the existing Vigilance control device it detects the drowsiness for behavioral measures in a non-invasive way, which will be preventing the Signal Passing at Danger (SPAD) in Electric locomotives

Effect of maraging steel on the bacteria occurring in drinking water: Zero cost water purification system

There are many villages in India, where there is no filtration and purification system. In recent years, there is considerable research in the field of water purification materials used in purifiers, filters, and chemicals used as antimicrobials. The traditional methods of water purification have many drawbacks, such as corrosion of containers used, coating dissolution, pitting and ageing effect and cost. Stainless steel has a corrosion problem which leads to an increase in impurities and costs. The plastic materials through have handling, transport, and cost advantage but they impart a smell due to dissolution of material of containers. Therefore, it is necessary and essential to avoid the drawbacks of traditional water purification and storage.

Effect of industrial effluent on the plant growth and activity of enzyme amylase

Industrial effluents are ranked as the highest pollutants among all industrial wastes. The industry effluent is highly toxic to flora and fauna due to the presence of excess amount of dissolved solids, chlorides, sulphides, chromium with a very high BOD, COD and conductivity in the effluent From the Common effluent treatment plant (CETP), treated effluent was analyzed for physico-chemical characteristics and its effect on seed germination, á-amylase activity and early seedling growth and 100% of the effluent, suggested á-amylase enzyme dependent inhibition of seed germination. In contrast, compared to the control, shoot length, leaf length, á-amylase activity (IU/g) and fresh weight biomass (g/plant) of seedling found to decrease as the effluent concentration increased.
