 Abstract

Nowadays due to increasing temperature conditions the application of different heat exchangers are to be developed to increase its performance. These heat exchangers are used in applications such as refrigeration, air conditioning systems, power plants, chemical processing systems, food processing units, automobile radiators and waste heat recovery units. In this study heat transfer analysis was done on the W Pipe heat exchanger type of coil. This analysis was performed for enhancement of heat transfer in a pipe using Nano fluids as coolants. Nano-particles such as Al2O3 and SiO2 are used along with base fluid water. Different concentrations such as 0.5%, 1%, 1.5% & 2% of nanoparticles are mixed with water. The study is done virtually by using ANSYS 15.0 fluent platform. Properties of Nano fluids are determined by using the formulations followed by base papers. The results such as pressure, velocity and heat transfer coefficient are determined. Results proved that Al2O3 has high heat transfer rate and also it is studied that SiO2 with water has high-pressure increase

 Abstract

Over the past years, summarization has become a topic of research. Various techniques of Natural Language Processing (NLP) enabling researchers to generate efficient results for a wide spectrum of documents. In the proposed work Seq2Seq Architecture with RNN is used to perform summarization tasks for documents. The nature of the summary is abstractive and allows the generation of internal meaning by the model itself

 Abstract

In the present study, the chitosan biopolymer was extracted from the bacterial and fungal species- Pseudomonas fluorescens, Aspergillus niger and Rhizopus oryzae. The chitosan was characterized by chemical treatment with iodine and concentrated sulphuric acid, characteristic colour change was observed, it indicates a positive result. The Chitosan yield was maximum in bacteria (Chitosan from Pseudomonas fluorescens 63%) than fungi (Aspergillus niger 20% and Rhizopus oryzae 15%) comparatively after 5 days of fermentation. Characterization by FTIR also confirms similar chitosan functional groups presence in the microbially extracted chitosan. The extracted chitosan was subjected to antimicrobial activity, and it was found that the extracted Chitosan was active against the bacteria (Bacillus, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus) and fungi (Candida albicans). In addition to the antimicrobial property of chitosan and drug, a combination of both chitosan and drug show higher antimicrobial activity when compared with the standard chitosan and drug. Thus, microbial chitosan could have potential in medical and agricultural applications. We can conclude that the strains used in the above work are promising sources for chitosan production. By recent developments in pharmaceutical biotechnology, these strains can be genetically manipulated and further optimized for getting better results in producing a quality and economical Chitosan.

 Abstract

In the virtually connected society of the 21st century, students are facing various challenges related to teaching-learning pedagogy. Especially, among college going students, problems like digital divide, usage of e-learning based methods, tools and techniques are prominent. So, in this paper, the researcher discussed about the requirements, meaning and challenges related to usage of online teaching-learning pedagogy by the students of higher education institutions. With this, this paper is majorly focused on the utilization of the updated and advanced Information and Communication tools (ICT) by the students for adopting the current teaching-learning pedagogy. For this, the quantitative research methodology has been utilized by the researcher. The sample has been taken mainly from the private institutions which make use of online platform for teaching-learning process. An online survey was conducted in order to target the age bracket (18 to 22). The result of the analysis suggested that after the era of covid, the utilization and usage of information and communication tools has been increased and with this the challenges associated with it has also surged.

 Abstract

The present study was undertaken in the Churu region of Rajasthan which is part of the Thar Desert. Churu is situated in the north of Rajasthan. This research provides special information about the stinging insects of this region. Stinging insects are belonging to the order Hymenoptera of class Insecta of the Arthropoda phylum. The researcher reported some of the stinging insects in the study area such as - honey bee, bumble bee, carpenter bee, yellow jacket wasp, hornet wasp, potter wasp, hunting wasp and paper wasps, etc. For the study of stinging insects, a sweep net was used for the collection of insects and laboratory work was also done by the researcher to study their venomous sting.

Abstract: This paper introduces quit-based job separation in the canonical DMP model. Here, we assume that a job is destroyed when worker quits the job and this can happen when wage paid to the labour is less than the reservation wage. This implies that job separation is endogenized by linking it to the reservation wage. In this quit-based job separation model we find that higher match productivity decreases steady state unemployment rate, but higher unemployment income and larger labour share increase this. Although we get similar results in the DMP model where separation occurs due to productivity shocks, our results are less calibrated in the regime of higher productivity and larger labour share.
