 Abstract

In advanced gas turbines, the turbine blade operated temperature is for above the melting point of blade material. A cooling scheme must be developed for continuous safe operation of gas turbines with high performance. A vital role is played by the compressor on jet engine as it concerns about the initial compression on engine bleed system and aircraft cooling. Two types of compressor are used in jet engine and that is axial compressor and centrifugal compressor. Here we work on axial compressor. As its major application, gas turbine engines are in large use. In this project NACA6409, NACA6412 and NACA64012 airfoil is taking for turbine blade. Turbine blade is designed in CATIA V5R19 and for analysis we are using ANSYS 18.1 software. Here we are using chromium steel, inconel-718 and inconel-625 as turbine blade material. Thermal and structural analysis is performing to determine the heat flux, temperature distribution and stress of the blade. And finally conclude which material is better with blade.

 Abstract

Opioids are frequently used as analgesics by HIV patients. Contrary to popular belief, new clinical data show that using opioid analgesics frequently really worsens the state of chronic pain. The World Health Organization's most recent study estimates that there are roughly 37.9 million HIV/AIDS patients worldwide. Around 30- 40% of them experience HIV-related discomfort. A significant percentage of chronic pain is neuropathic pain, which is described as chronic pain brought on by diseases or lesions of the nerve system and manifesting as a variety of symptoms of the neurological system, including both positive and negative signals. HIV-related neuropathic pain is believed to be generated by a maladaptive process that initially served to promote regeneration and healing injury induced by HIV protein, central and peripheral sensitization, and side effects of antiretroviral medication. It has been discovered that Gp120, an HIV envelope protein, is the main toxin that causes neuropathic pain. In particular, during HIV infection, the microglia, which release a variety of pro-inflammatory molecules (including TNF, IL-1, and IL-6), not only cause the neurons to become more sensitive, but they also play a key role in the cross-talk connecting the astrocytes and oligodendrocytes to create the central sensitization.This review mainly focus on the mechanism of hiv related neuropathic pain and association with opioids

 Abstract

Industrialization changing the gaseous composition of earth's atmosphere. Air pollution affects both plants and animals. Pollutants causes change in stomatal pores seems to be adverse effect with respect to survival of the plant during stress. In this study estimate chlorophyll of green leaves taken from urban area and garden area. It is well known that chlorophyll is essential for photosynthesis, allowing plants to absorb light energy and transformed into chemical energy. Respiration and other metabolic activities also get affected by air pollutants. Paper chromatography method used in this work. The qualitative comparisons of chlorophyll content between garden area and urban area leaves were observed. Four plant species were selected namely (Pluoneria acutifolia) Champa, (Bougainville glabra) Bougainvillea, (Tecoma gaudichaudi) Tecoma, (Senna siamea) Cassia for this analysis.

তুলনামূলক বিশ্লেষণ করতে হলে একই গোত্রের দুই বা ততোধিক বিষয়ের মধ্যে তা করতে হয়। অর্থাৎ তুল্য বিষয় বা বস্তুগুলোতে অনেক বৈশাদৃশ্যের মধ্যেও কোথাও না কোথাও শাদৃশ্য থাকতে হবে। এই দিকটিকে মাথায় রেখেই আমরা বাংলা ও অসমীয়া ভাষায় লেখা দুটি নদীকেন্দ্রিক উপন্যাসকে বেছে নিয়েছি বিশ্লেষণের জন্য। এই দুটি উপন্যাস হল মানিক বন্দোপাধ্যায়ের ‘পদ্মানদীর মাঝি’ ও নবকান্ত বরুয়ার ‘কপিলিপরিয়া সাধু’। মানিক বন্দোপাধ্যায় বাংলা সাহিত্যের একজন প্রখ্যাত ঔপান্যাসিক। তাঁর লেখা ‘পদ্মানদীর মাঝি’ উপন্যাসে পদ্মাপারের জেলে-মাঝিদের জীবনচিত্র ফুটে উঠেছে। ফলে এর মধ্যে আঞ্চলিক উপন্যাসের বৈশিষ্ট্য লক্ষ করা যায়। অপর দিকে নবকান্ত বরুয়া অসমীয়া সাহিত্যের একজন বিশিষ্ট ঔপন্যাসিক। তাঁর লেখা ‘কপিলিপরিয়া সাধু’ উপন্যাসে কপিলি নদীর তীরবর্তী মানুষের জীবনবৃত্তান্ত বর্ণিত হয়েছে। ফলে এটিও আঞ্চলিক উপন্যাসের লক্ষণাক্রান্ত। উভয় উপন্যাসে লৌকিক সংস্কার, লোকবিশ্বাস, বিভিন্ন সামাজিক রীতি-নীতির পরিচয় পাওয়া যায়। এরকম বিভিন্ন সমতার মধ্যেও অনেক অমিল খুঁজে পাওয়া যায়। যেমন ‘পদ্মানদীর মাঝি’ উপন্যাসের তুলনায় ‘কপিলিপরিয়া সাধু’ উপন্যাসে অধিক পরিমানে লোকসংস্কৃতির উপাদান খুঁজে পাওয়া যায়। আবার পদ্মাপারের আঞ্চলিক ভাষার প্রয়োগ যেভাবে ‘পদ্মানদীর মাঝি’ উপন্যাসে পাওয়া যায়, সেভাবে ‘কপিলিপরিয়া সাধু’ উপন্যাসে পাওয়া যায় না।

 Abstract

Background: Forward head posture is being seen as one of the most common postural problems in the general population. Despite much research on this sensitive variable, there is no clear-cut correlation regarding these. Moreover, with the increased usage of computers mainly in the area of banking where a person sits in a computer for several hours raises several health issues, resulting in FHP, Neck pain, and various other problems. The main objective of this observational study is to assess the correlation among forward head posture, and functional status associated with neck pain in bankers working in Arunachal Pradesh. The study is based on an observational based design, (n=100) was taken randomly. Method: Banking professional workers (n=100) participated in this study on the basis of inclusion and exclusion criteria. The data collection was done via tragus-to-wall test for the measurement of FHP, NPRS for pain measurement, and NDI for Functional Disability. Results: This observational study states that there is a significant negative correlation of FHP, Neck pain associated with Functional status. This may be said that there are other factors that may have a direct response of correlation with these variables. Conclusion: The study signifies that the variables FHP, and Functional status related to neck pain in banking professionals almost had no direct effect on relation to one another. The decisive reason for their poor health issues may be due to including the absence of ergonomic training, working hours, and no physical workout.

 Abstract

Based on the Elliott Wave, the market goes in predictable ways in response to shifting investor sentiment and price momentum. Crowd behaviour will mainly shift from optimism to pessimism and around again, allowing for the prediction of the development of some market movements. R.N Elliott discovered The Wave Principle, which states, social or crowd behaviour shifts and trends in observable patterns. The Wave Principle offers a thorough explanation of how markets function, not just a technique for predicting. This Wave Principle is employed in numerous areas of widespread human behaviour, but the financial sector is the area where it is frequently used. In fact, the stock market is much more significant when looked at in isolation than casual speculators might think along with Elliott's theory this paper includes timings of wave completion of impulsive and corrective waves from the technical study of 3-4 thousand charts.

 Abstract

As literature reflects society, dalit or tribal literature is, no doubt, the document of dalit or tribal society and its people. Generally, it is known to all that dalit or tribal people, belonging to the lowest strata of caste system in our society, are 'untouchables' in traditional 'Varna' system. Being subaltern section of society, they have been exploited economically, discriminated socially and marginalized culturally by upper caste people throughout the ages. They have been forced to be deprived of education. So, they are mostly illiterate and they can easily be fooled by hypocrites. On the other hand, belief in superstition comes out of ignorance and illiteracy which co-exist in society. This paper attempts to study systematically the superstitious practices and beliefs of these rural and tribal people with reference to Anil Gharai's Reincarnation of Parashuram, a story which explores how a tribal family suffers from superstitious beliefs and practices, seeks remedy of its ailing child with the help of a gunin, and shows how an aged mother is labeled a 'witch' and killed by her son as in the myth of Parashuram. This paper also discusses how a rural tribal family as well as society has been ruined only because of superstitions and acts of ignorance.

 Abstract

English language has become an important part of school education in India and all over the world. Hence, it is essential to teach English at different levels of an academic system. This research study aims to find out the awareness levels of the English teacher, to examine the methods, techniques, approaches and teaching materials being used by the teachers, to study the problems faced by students and English subject teachers in teaching learning process and lastly, to examine the strength and weakness of teaching English at secondary schools in Tripura. This study employed survey type of research method and with 130 samples as participants. The data were collected by using self-developed questionnaire for English subject teachers, focus group discussion on students, classroom observation schedule and interview schedule on English subject teachers. The study revealed that majority of English teachers were having awareness of English teaching for facilitating self and peer assessment, group activities, low level of students' interest, over dependent on teachers; irregular of students' participation in the class, and language barrier related challenges faced by English teachers. Majority of the schools had lack of Computer lab, school library, school magazine, ICT facilities etc. The challenges of teaching and learning of English Language teachers can overcome by providing in-service training to English teachers along with the provision of minimum facilities in the schools.
