In the steel industry, competitive pressures such as worldwide demand, high cost of energy, environmental and safety regulations, competing materials, customer demand for high quality, and the high cost of capital have led to a need for changes across the industry. Refractories for all unit processes are selected on the basis of their longevity and the cleanliness of the steel. The various types of refractories influence the safe operation, energy consumption and product quality; therefore, selecting refractories to each application is of great importance. This study discusses the types, characteristics and properties of various refractories suitable for steel plant lad

The construction industry involves risky and unhealthy operations which result in many human tragedies, to lose enthusiasm of workers, disrupt construction, delay progress, and adversely affect cost, productivity, and reputation. The complex nature of construction and hazards it have occupational health and safety in construction work should design table and continue throughout the construction phases until the safety and health of every end users is ensured. Safety is a major concern for construction companies, as it is a source of substantial direct and indirect costs. In some countries, the rate of total workplace injuries from construction activities can be as high as at least 50%. This is undoubtedly a serious matter warranting urgent attention. This paper reviewed that the safety problems at construction site with fetal injuries caused by it with help of different graphical data of agencies .It gives detailed information regarding about the injuries type and physical loss of human from this. This study also revealed that the importance of safety in construction should pay more attention as the injuries loss the human life and also delay in completion of project

An experimental study of heat transfer in plane circular tube fitted with the V-Shaped Aluminum turbulators is performed for plane circular tube. The objective of this Project work is to analyses heat transfer coefficient and friction characteristics in a plane circular tube fitted with the V-Shaped Aluminum turbulators. The experimentations are firstly carried out on the plane circular pipe and heat transfer augmentation were recorded and then the v-shaped Aluminum turbulators are fitted in the same plane pipe and then again the heat transfer augmentation is recorded and then both of them is compared. Experimental investigations have been carried out to study the effects of the V-Shaped Aluminum turbulators on heat transfer, friction and enhancement efficiency, in a circular tube. We used the V-Shaped aluminum turbulators with the turbulator element length of 200mm, 160mm and 120mm.We found the heat transfer argumentation.The mean heat transfer rates obtained from using the V-Aluminum turbulators are 198%, 213% and 241% for turbulator element Length of 200mm, 160mm and 120 mm respectively. All of the experiments are carried out at the same inlet conditions with the Reynolds number, based on the tube diameter (Re), in a range of 3000 to 10000

Sentiment Analysis is the process of finding the sentiments from different classes of words. Generally speaking, sentiment analysis aims to determine the attitude of a speaker or a writer with respect to some topic or the overall contextual polarity of a document. The attitude may be his or her judgment or evaluation, affective state, or the intended emotional communication. In this case, ‘tweets’! Given a micro-blogging platform where official, verified tweets are available to us, we need to identify the sentiments of those tweets. A model must be constructed where the sentiments are scored, for each product individually and then they are compared with, diagrammatically, portraying users’ feedback from the producers stand point. There are many websites that offer a comparison between various products or services based on certain features of the article such as its predominant traits, price, and its welcome in the market and so on. However not many provide a juxtaposing of commodities with user review as the focal point. Those few that do work with Naïve Bayes Machine Learning Algorithms, that poses a disadvantage as it mandatorily assumes that the features, in our project, words, are independent of each other. This is a comparatively inefficient method of performing Sentiment Analysis on bulk text, for official purposes, since sentences will not give the meaning they are supposed to convey, if each word is considered a separate entity. Maximum Entropy Classifier overcomes this draw back by limiting the assumptions it makes of the input data feed, which is what we use in the proposed system.

Rural communities in Garhwal Himalayan region face a range of socio-economic and environmental problems. The area of the present study is district Rudraprayag, Uttarakhand. This hill district has subsistence farming as their main economic activity. Due to subsistence livelihood, migration and a remittance based economy operate in the district. The potential of innovation/technology has not yet been adequately and appropriately harnessed to overcome the development constraints posed by the fragile Himalayan environment. As government made many efforts to boost the process of innovation adoption, the technologies currently restricted with only few progressive farmers. Thus, there is a need for agriculture diversification and large-scale extension of region specific technologies for enhancing the economic condition of rural poor/smallholder household. This study focuses on the issue of agriculture diversification, potential areas of diversification and need of diversification with the need of technological adoption.
