 Abstract

Mixed flow compressor module is employed in machines such as gas turbine engines, steam turbines marine applications and power generation purpose. Mixed flow compressor impeller is cad modeled and analyzed for thermo-mechanical stress for improvement in the structural ability for load carrying capacity. In this work mixed flow compressor impeller is cad designed based on the centrifugal compressor design methodology for given operating conditions. The geometric modeling of the impeller was done using the modeling tool catia and it was imported to Hyper mesh for meshing then exported to ANSYS through input file in ‘in’ file format for the subsequent analysis. The impeller was analyzed for different loads such as inertial and thermal loads and cyclic symmetric boundary conditions. The impeller shaft analyzed for natural frequency and mode shapes to avoid resonance conditions. Thermal barrier coating materials are used to reduce the heat transfer to the system and its structural ability is estimated. A layer of composite thermal barrier coating is created using hyper mesh and the effect of this on stress behavior is analyzed. The results shows reduction of deflection and stress with low thermal expansion coefficient material. Even composite material has lesser thermal conductivity along with density compared to the parent titanium material. This character of composites can be effectively utilized to increase the load carrying capacity of the impeller. The impellers can operate still at higher frequencies with this composite cladding. Modal analysis is carried out to find the resonant frequencies. The results show the first natural frequency of 1332 Hz is much higher compared to the operational frequency of 783Hz. So resonance will not takes place in the problem.

 Abstract

Teaching skills like listening skills is one of the difficult skills for a long time for the second language learners in India. In most of the second language contexts availability of accurate pronunciation of speech sample from the teacher or authentic material is a bit difficult. So, in the most of the cases it is neglected in teaching and learning because the individual leaner needs of it are very unique. As a consequence it has been an under achieved skills in the language learning process. Moreover, most of the time students were depending only on teacher for all varieties of language needs. Until 2010 there is a little help in acquiring the listening skills or any other language skill for that matter among the students even in the elite institution. This is just one example of meeting the actual leaner needs in the face to face classroom. With the advancement of technology in mobile phones and computers and related technology in the current decade gave a new way to teachers and students to teach and learn listening skill with Apps became a new way of learning and the pace of teaching or learning with it actually increased. The most important change we can see is teaching or learning listening skills with digital technology and mobile Apps. Through, mobile Apps and digital tools the target learners may attain more learner autonomy. In this regard, this paper tried to explore the available digital tools and mobile Apps which are very useful in language acquisition. The information of same was brought to the knowledge of the learners and was informed to use them for their language use. After the usage of the Apps learners interviews were conducted to know their opinion on using those apps. In this study students achieved positive results in terms of language improvement especially, pronunciation and learner autonomy.

 Abstract

Mushrooms have been used as valuable food for a very long time because they are highly nutritious, with the necessary tremendous amount of quality proteins, vitamins, minerals, etc. Mushrooms are rich, diverse sources of various bioactive compounds extracted quickly by different extraction procedures. In the present study, Ganoderma lucidum was possessed for extract preparation of mixed polar and non-polar solvents. The extracts solvents were analyzed for potential antimicrobial property determination of crude extracts by disk diffusion and minimum inhibitory concentration (MIC) methods and successfully investigated the antimicrobial potency. The results indicated that polar and non-polar extracts from Ganoderma possessed potential antimicrobial activities against the tested organisms, i.e., Bacillus tequilensis and Bacillus subtilis. The present study suggests that the Ganoderma mushroom containing bioactive compounds has potent antibacterial capacity; future complete profiling of bioactive compounds will be a new dimension for research and drug discovery.

 Abstract

The paper addresses the question of existence of land mortgage under usufructuary system in agriculture of Assam. It is well known that when a small farmer needs loan they can easily receive it by mortgage their land to the landlords. This system, however has been on the increase during the current decades. A number of explanatory factors have been considered to explain this phenomenon. There is a considerable scope here for they to catch up with the empirical findings. Our findings, primarily based on the field survey data, suggest that among the factor considered intensity of informal credit transactions are the most important ones to explain the forms, nature and extent of informal credit transactios in agriculture of Barak valley during the current decades.

 Abstract

The interline power flow controller (IPFC) is a flexible AC transmission system (FACTS) controller that is used to govern power flows across various transmission lines. This paper describes a mathematical model of IPFC known as the power injection model (PIM). The controlling of active and reactive power flow may be accomplished by calculation of currents as a function of the target power flow and the bus voltage at the IPFC terminals. However, the reactive power flow is discharged and computed based on the system. The injected currents are updated and added to the load flow algorithm's initial current mismatches vector IEEE-9 bus system is used to investigate power flow regulation with the Newton Raphson (NR) power flow algorithm in transmission lines with IPFC. The MATLAB platform was used to expand the usual Newton Raphson (NR) technique.

 Abstract

Attempt were made to apply Taguchi method to find out the best experimental condition to get high specific capacitance of synthesized carbon material. Taguchi method involves reducing the variation in a process through robust design of experiments. The overall objective of the method is to produce high product result in minimum steps. From capacitance studies done by cyclic voltammetry technique for carbon materials obtained from plant precursors like Castor seed (Ricinus communis), Ritha seed (Sapindus mukorossi) and Jackfruit seed (Artocarpus heterophyllus) shows that highest specific capacitance is obtained with carbon obtained from Jackfruit seeds. Taguchi optimization methodology predicted that carbonization of Jackfruit seeds at 900oC temperature for 4 hrs duration and treatment of carbon with 50 % KOH solution gives the carbon of best quality for maximum capacitance. It is also observed that, first major impactful parameter on the specific capacitance is the nature of the precursor and second is treatment with KOH; pyrolyzing time and temperature had very little impact.

 Abstract

Poetics is one of the fields of knowledge in which Indian scholarship has made significant contribution. But a feeling of regret arises when we find that Indian Poetics has not been properly appreciated by scholars. My goal in other words, is to show that art of reading poetry can be as fascinating and as creative as the art of writing, if we have our own critical tools . Rajagopal Parthasarathy, an Indo-Anglian poet says: Language is a tree, loses colour under another sky.(Rough Passage, 17-18) Thus the present paper is a modest attempt to apply the Dhvani theory of Indian Poetics on the selected canvas of English and Sanskrit Literature.The focus of the paper is to counter and correct the de-intellectualized mind by arguing for and developing applicational model from Indian Sanskrit literary theory of Dhvani to a wide variety of English texts.

 Abstract

Microorganisms, mainly fungi, are responsible for the biodegradation of various cellulosic materials, like cotton textiles, linen goods, paper and pulp products, rubberized articles, leather, rexine and plastic products, such as ropes, twines, water proof covers and many other articles used in defence services under tropical and sub-tropical conditions. Even the electronic components have not been spared from fungal damage. The damage caused by the attack of microorganisms on cellulosic materials is so enormous that the use of fungicides becomes inevitable. The present work deals with the effect of two potent fungicides- - m-Dinitro benzene and Pentachloro phenol on the growth of a highly cellulolytic fungus Aspergillus niger.
