 Abstract

With the continuous rise in the load demand at consumer end, the performance of the existing operating electrical machines gets affected. The increasing temperature of earth’s surface due to solar radiation is another reason of the rise in the temperature of the electrical machines. Power transformers are one of the electrical machines whose performance is directly affected by its inner and outer temperature values as they are generally installed outdoors. The life of the power transformer reduces gradually with the time and sometimes the severe outdoors surface temperatures may lead to sudden explosions that also obstruct the operation of the other associated machines as well. Therefore, thermal modeling of outdoor power transformers should include the consideration of variation in environmental temperature. This is expected to create an opportunity for the research in this field. This includes developing computational thermal models simulation using appropriate software tools. These models can be employed to evaluate the actual operational age of power transformers by estimating equivalent life at the reference temperature on the basis of the time period of the estimated temperature cycle causing acceleration of aging. This paper presents a MATLAB/ Simulink based thermal model determining temperature in increasing the aging acceleration factor, which has been used for estimation of the loss of life of the transformer. Further, the effect of outdoors surface temperature due to the influence of solar radiation for increasing the loss of life of power transformer has also been studied and verified by using the thermal model. The proposed model has been validated using real time data gathered from the power transformer in operation at 220kV GSS, Jhalamand, Jodhpur.

 Abstract

Azelastine is among the most frequently used drugs; however, knowledge and solid data about its metabolites are scarcely found in literature. By oxidation of azelastine with H2O2, these N-oxides were now prepared in racemic form for the first time and were fully characterized. Their structure was additionally confirmed by a single crystal X-ray analysis. Both N-oxides were found to be non-cytotoxic in SRB assays.

 Abstract

The story of the progress and evolution of human has been an unending episode. From being the hunter-gatherer in the pre-historic times to the modern techno-savvy man, this journey has been remarkably significant. Human beings have travelled a long way to mark themselves as the most prominent species on this earth. This entire process of human advancement has been documented since ancient times and can be well understood by going through the pages of literary texts. The literary treasures hold in themselves the mesmerizing accounts of the development of human civilization and culture. They help us to walk back in time and develop better understanding and appreciation of the past. It is enthralling to witness how the great civilizations like that of the Harappa and the Mesopotamia flourished but got eroded due to natural calamities and disasters. With the changes in the human society, literature too has evolved. It is very true to say that literature acts as the mirror to the society. The novels, poems and literary texts belonging to a particular period gives one a clear picture of the culture, society, norms and beliefs of that period. The authors, poets and literature experts pour their heart out to artistically portray the customs, culture, rituals and society of the era to which they belong. We also find the glimpses of the societies through the literature of a particular period. A society is not only about the individuals living together, instead it is an amalgamation of the material objects, culture, beliefs, traditions as well as the resources available. Innumerable human societies have been formed and wiped out on this earth since time immemorial. Natural factors like floods, droughts, pandemic and other natural calamities had played a major role in the extinction and loss of many such human settings and dynasties. In the present world of growing globalization and mass media, the world wars and other disasters have made the human life vulnerable. Literature today mostly focusses on the individualities of human beings. This current covid pandemic has created a vacuum in the lives of people. It feels as if people have forgotten the eagerness and jest to strike conversations and communicate with one another. Literature too has suffered from an immense lack of motivation and creativity. It has developed a situation of creative blockage in the present era. It seems as if the past few years of covid crisis and lockdown has shunted our personalities and made us morose and dull. It has put forward a haunting shadow like that of a vampire over the entire humanity. It appears as though the covid vampire algae is going to endanger the human race sucking its blood and peace.

 Abstract

The present review highlights overall nutritional composition as well as major health benefits associated for its better utilization in Indian food industries. Kiwifruit is scientifically known as Actinidia deliciosa, native to Asia (majorly central or eastern China) is popular worldwide due to valuable nutritional and sensorial properties. Being the richest source of fruit sugars, vitamins, minerals and other valuable bioactive compounds, it is highly researched on throughout the world. Kiwifruit is known to work well against digestive issues, cardiovascular diseases, skin health, diabetes, inflammation and microbial action etc. which makes it well suited for therapeutic interventions as well as food applications.

 Abstract

Concrete, is one of the key construction materials having good compressive &, flexural strengths and durable properties among others. With comparative low cost made from some of the most widely available elements, it has found wide usage. It is mouldable, adaptable and relatively fire resistant. The fact that it is an engineered material which satisfy almost any reasonable set of performance specifications, more than any other material currently available has made it immensely popular construction material. In fact, every year more than 1 m3 of concrete is produced per person worldwide.As our project title suggests, the objective of our project is to find out the strength parameters, in specific, the compressive and flexural strengths.
