A PIONEERING SCAFFOLD FOR EMPLOY REINFORCE SLAB MIXTURE

Within this project, we view and studied completely some utilizes a site associated with publish tensioned slabs. The different sizes of tendons available, what are materials imparting prestress towards the structure were studied completely. We've also understood and performed building column line staking on-site. The tendons are specified by the forms in compliance with installation sketches that indicate the way they should be spaced, what their profile ought to be where they should be stressed. Following the concrete is positioned and it has arrived at its needed strength, usually about 75% of their final strength, then your prestressing process begins. The key is the fact that once the tendons are extended, want revisit their original length but they are avoided from doing this through the anchorages. The truth that the tendons are stored inside a permanently stressed condition leads to a compressive pressure to do something around the concrete. This considerably boosts the load-transporting capacity from the concrete. Since publish-tensioned concrete is cast in position in the job site, there's very little limit towards the shapes that may be created. Curved facades, arches and complex slab edge layouts are frequently a trademark of publish-tensioned concrete structures. Publish tensioning is just evolving increasingly more with growing innovation of creative and atmosphere friendly materials. An essential aspect to become stored in your mind may be the sustainability. Publish tensioned concrete has a lot of advantages in comparison with conventional RCC construction, probably the most important to be the decrease in self weight and overall decrease in the advantages of materials

Development of eAgromet Prototype to Improve the Performance of Integrated Agromet Advisory Service

In several countries, the systems for forecasting weather are being operated to deal with weather and its related factors affecting agricultural production. India meteorological department (IMD) is providing several types of weather forecasts. One of the forecast service is medium range forecast (MRF). As a part of MRF, the expected values of rain fall, temperature, cloud cover, humidity, wind speed and wind direction for next five days are forecasted twice a week by considering district as a unit. Agriculture is markedly affected by weather condition during crop season. IMD in collaboration with Indian Council of Agriculture Research (ICAR) and State Agriculture Universities (SAUs) has set-up about 130 Agro-meteorological Field Units (AMFUs) and each AMFU covers about five districts. Based on MRF, IMD is rendering Integrated Agromet Advisory Service to the farming community of the country in the form of agromet advisory bulletin. The agromet advisory bulletins contain possible risk mitigation measures for the major crops and livestock. Based on the weather forecast, a group of interdisciplinary scientists and agromet scientists at AMFU prepare district-level agromet advisory bulletins. These bulletins are sent to the farmers and other stakeholders of the corresponding district. To ease the process of preparing agromet bulletins, an effort has started to build IT-based agrometeorological advisory system called, eAgromet. In this paper, we explain the concepts of eAgromet and its operation

Environmental monitoring using biomarkers in relevance to heavy metal pollution in coastal areas of the Gulf of Mannar

Marine organisms are vulnerable to harsh environment where fluctuation in physicochemical conditions including salinity and tides are common. These organisms over the period have evolved different mechanisms to maintain the physiological conditions of the body through metabolic activities. In the present work, we studied accumulation of about 10 heavy metals in about 20 marine organisms from the Gulf of Mannar, Southeast coast of India and also explored the passable relationship between distribution of these inorganic metals and biochemical response of these organisms. The effect on the accumulation of metals over the metabolism in the marine animals was evaluated by the level of antioxidant response. Concentration of metal in the body tissues was analyzed using ICP-AES. Interestingly, it was also observed that genotoxic potential pollutants were less or negligible in the selected sites. Tail DNA in the muscle cells was observed to be <5%. Our study concludes that fishes from the two areas are not heavily burdened with metals, but pollutants should be monitored periodically to avoid excessive intake of trace metals by humans due to bioaccumulation. The work concludes that a multiparameter analysis should be followed to study the ecological status of the aquatic environment

Biomarkers as ecological indices in monitoring the status of market fish

Abstract Background Environmental contamination has become a major concern over the past few decades, drawing the attention of numerous researchers from both developed and developing nations. The aquatic system serves as the primary sink for the disposal of garbage, which has a negative impact on the aquatic environment and biota. The reality is that heavy metals cannot be totally removed from the ecosystem because they can bioaccumulate and grow in strength as they move up the food chain. Particularly heavy metals can build up in the tissues of aquatic animals, and as a result, tissue concentrations of heavy metals may be harmful to both human and animal health. Our study aimed to elucidate the possible use of biomarkers in monitoring and assessing the heavy metals contaminants among fresh water fish. Results From the present study, we conclude that glutathione peroxidase can be used as the bioindicator for nickel and iron contamination. Ultimately, these studies focus on measuring levels of pollution that may induce irreversible ecological changes to aquatic ecosystems. Till now the level of toxicity was moderate, and it was progressing toward the danger. Efforts can be made to control the activities that release pollutants unnaturally into the environment from both public and government so that the clean and clear environment can be maintained. Conclusions The work concludes that a multiparameter analysis is needed to assess and monitor the ecological status of the aquatic environment
