Health Propaganda and Health Consciousness in Jalpaiguri (1880 - 1945) : A Historical Overview
Authors: - Sumita Roy Choudhury
Published: June 2023

The present study focuses the practices of British Govt. on Health & hygiene in Jalpaiguri district which constitute the health propaganda during colonial phase. British Raj extracted huge revenue from tea gardens of Jalpaiguri but spend a fragment of it in health services. The Director of Public health too regularly informed about the shortage of fund to regarding various public health schemes. To spread the govt. policies for the health services and maintain the hygiene in different community various steps were taken but did not reach to the labor line areas of various plantation industry and other rural parts of Jalpaiguri district. The role of the govt. journals was also not satisfactory in this regard because of lack of interest of colonial government. Sources gathered that many preventive measures were taken like malaria Vaccination, distribution of western medicines, mosquito net etc. as safety measures in other parts of Bengal but Jalpaiguri was kept untouched. Facilities were provided for Europeans but not as a whole for the commoners, Govt facilities were in paper but not in practices in real sense. The minimum facilities regarding health and hygiene were ignored by colonial ruler and mortality rate increased in Jalpaiguri. Though climate of Jalpaiguri was also very favorable in this regard and gradually Jalpaiguri became the store house of all diseases. Few charitable hospitals were built for minimum health services after world war I to meet the challenges but were very minimum which forced the people to depend upon indigenous medicines.

Published: June 2023

Coffee is one of the most popular commodities, including in the international market. The process in developing the Robusta coffee commodity and increasing its economic value is to make fermented coffee into wine coffee. Coffee wine fermentation is traditionally placed in a closed place or container without temperature control and pH value checking. This study aims to create a fermentor system that can control temperature, detect pressure in the fermentor and determine the pH value in the fermentation process. Temperature control in the fermenter uses the PID (Proportional Integral Derivative) method. The PID controller determines the setpoint of 31oC. The actuators of the system are a series of thermocouples and TRIAC which control the light of an incandescent lamp which is a source of heat to raise the temperature in the fermenter. The fermentation process is complete when the pH value has touched 4. The results of this study produced fermented coffee which had a pH value of 4 using a fermenter for approximately 4 weeks, while for the traditional method without temperature control it took approximately 6 weeks. Testing the caffeine content in coffee before fermentation was 2.43% and the caffeine content after fermentation was 2.00%.

Empowering Women Through Timbaktu Collective
Dr.G.Ramamohan Reddy
The basic activity is formation of Self¬ Help Groups (SHGs) which is the organizational base for the eco¬nomic activities of women. These groups are federated at the Mandal level as MATCS (Mutually Aided Thrift Cooperative Societies)-Adisakthi MATCS in CK Palli Mandal, Ananthasakthi MATCS in Roddam Mandal, and Mahilasakthi MATCS in Ramagiri mandal. Taking these fur¬ther, a federation of the Societies has been formalized as the Mahasakthi network. The network focuses on improved governance of the Societies and approaches to solv¬ing broader social issues faced by the members. The work of the Societies takes place chiefly through thrift (sangha) meetings that happen weekly. Each Society runs a legal aid and counseling cell in their respective Mandal for helping members resolve family and other social issues that often need legal support.
In this paper an attempt is made to analyze the impact of Timbaktu promoted SHGs on sample respondents. Before analyzing various impacts an attempt is made to present socio- economic background of respondents, which have far reaching impact on various impacts.

Optimal Portfolio Investment and Consumption Strategies in Indian Equity Market
Authors: - Sangita
Published: June 2023

A number of investment strategies map out to maximize portfolio growth are tested on a long run Indian equity market. The application of the optimal portfolio techniques produces magnificent rate of growth, In spite of the fact that the assumptions of normality. Optimal portfolios are constructed by rebalancing the portfolio weights of four indices and ten sectors of National stock exchange indices. The purpose of this paper is to examine the Optimality of the Portfolio in the NSE and examine hypothesis the application of efficient market. The sample of stocks is not large in spite of its comprehensiveness from the local stock market . This paper also analyzes optimal portfolio and consumption strategies with unobservable states and predictability of risky asset returns. We develop approximate analytical solutions to the unconstrained dynamic problem. The approximation is shown to be fast and accurate. The computation time of the approximate solution is shown to be practically independent of the number of assets when no predictors are present and only marginally affected by the number of predictors. While the portfolio policy strongly depends on the current state of the economy, the consumption-to-wealth ratio is violently state-independent. Hedging demands are negligible with regimes and no predictability, but are important with predictability. On the other hand, the consumption to wealth ratio is not very impacted by the predictor. We provide an out of sample statistical assessment of the returns provided by a multi-regime strategy with respect to a single-regime and to a 1/N strategy.

Authors: - Kavya Mohan
Published: June 2023

About 50% of students study in private schools but private school teachers’ has been subject to exploitation for a long time. The difference in terms of contractual employment of teachers in government and private schools are explained using a review of the available literature. Improper dismissal, unfair contract terms, inadequate and irregular payment of salaries are identified as the major problems faced by private school teachers. This article analyses the lacunae in current state laws regulating private schools in Tamil Nadu. The terms of employment of teachers in government and private schools are compared using secondary data derived from reliable sources. Teachers are forced to strike and engage in public agitations to assert their rights as otherwise they are burdened by long litigations in courts. Judiciary’s approach towards private educational institutions is traced through various decisions of the Supreme Court and high courts.

The Positive Influences of Master Nagarjuna’s Treatises on Tibetan Culture
Authors: - Lhundup Dorjee
Published: June 2023

The topic for my article is ‘The Positive Influences of Indian Master Nagarjuna’s Treatises on Tibetan Culture’ and I have broadly divided this article into two parts, namely: 1. The Treatises’ Influence on the Lives of Ordinary People, and 2. The Treatises’ Influence on the Lives of Monastic Community. Generally speaking, there are six volumes of Master Nagarjuna’s treatises translated into Tibetan language by Tibetan translators, but I am going to write my article mainly based on treatises like, Fundamental Verses on the Middle Way (Mulamadhyamakakarika), Entry into the Middle Way Principle, A Letter to the Friend, The Four Hundred Verses Treatise, and A Guide to the Boddhisattva’s Way of Life.
The purpose of writing this article is not only to share knowledge, but also to express this ancient Indian Buddhist philosopher’s marvellous contributions to the development of Tibetan culture and its effective relevance to the entire humanity even in the 21st century. In addition, the importance of continuous preservation and study on the above-mentioned treatises is also something that seriously needs to be taken care of.
The method to be adopted here would be qualitative method as I am going to refer to treatises composed by this great Indian Master and their commentaries written by Tibetan Buddhist scholars like, Gyal Tsob Dharma Rinchen, Ngulchu Thokmey Sangpo, and Je Tsongkhapa, the founder of Gelug tradition. These treatises have been used at different Tibetan Buddhist Learning Centres across the world for hundreds of years and they have tremendously given powerful impacts on the way of leading lives and the manner in which the external phenomenon is perceived. In other words, they have rendered a well-balanced space regarding the relationship between the object to be perceived and the perceiver or the person.

Intrusion Detection using Machine Learning: A Random Forest-based Approach
Authors: - Ch. Sai Sampath , - P. Anuradha
Published: June 2023

It can be very difficult and time-consuming to pinpoint network traffic behaviours that frequently disrupt services. A researcher must check out all the massive and off-course data to discover the chain of network link interruptions. A system administrator is to be notified by an intrusion detection system (IDS) each time an intruder attempts to breach the network. Using a table of harmful signatures, an IDS that has been mishandled inhibits attacks. An alarm is triggered if a persistent exercise matches a signal on the chart. These kinds of systems are used by countless organisations and institutions worldwide. They are simple to use, let administrators tailor the sign table, and help identify the real facts of events. An Intrusion Detection System (IDS) has been developed that employs various machine intelligence techniques to automatically identify assaults on intricate networks and systems. Principal component analysis (PCA), along with several classification algorithms including Support Vector Machines, Random Forest, and K-Nearest Neighbor, is used in an effort to increase the capabilities of IDS. Attack detection is the principal function of an intrusion detection system. Nonetheless, identifying intrusions as soon as possible will help to lessen their damage.

Published: June 2023

Tonsils function as a defense system and aid in keeping your body free of infections. About 5% to 40% of cases of tonsillitis are caused by bacterial infection, which is the most frequent cause of the condition. There are several different forms of tonsillitis, including viral tonsillitis and bacterial tonsillitis, which is brought on by bacteria like streptococcal pharyngitis. Tonsil redness and swelling are its symptoms. Tonsils that are covered in white or yellow patches or have a sore throat, swallowing problems, fever, swollen tonsils, etc. There are just a few treatment options, including surgery to remove the tonsils, medication such NASIDs and antibiotics, and home remedies. A tonsillectomy is a surgical procedure that totally removes the tonsil. Different methods are used to accomplish it. Any method of tonsillectomy is acceptable as long as the crypts are kept open and some tonsil tissue is left behind, including laser, radiofrequency, shaver, coblation, bipolar scissor, and Colorado needle. Even the finest surgeon will have a postoperative haemorrhage because bleeding is a possibility with all surgical methods. After cold dissection with ligature or suturing, there is the least chance of haemorrhage. A increased risk of late bleeding exists with all "hot" procedures using laser, radiofrequency, coblation, mono- or bipolar forceps. In seriously afflicted infants with recurrent tonsillitis, an antibiotic allergy, PFAPA syndrome (periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis), and peritonsillar abscess, total extracapsular tonsillectomy is still advised. It affects the patients' immunity.

Placebo is the second-best remedy in Homoeopathy. In the day-to-day practice certain situation arise which lead us to prescribe placebo. Beginning from the case taking when the patient is taking some medicines, to the end of the treatment when homoeopathic aggravation occurs, in all that time physician requires placebo. In the middle of the treatment process placebo is needed during homoeopathic aggravation, improvement of the case. Certain disease conditions like Artificial Chronic Disease, Pseudo Chronic Disease, Mental diseases of emotional origin, Indisposition, Hypochondriac patients demand placebo. In randomized controlled trails with homoeopathic medicines the value of placebo is unquestionable.
Monoclonal Antibody Purification with Reduced Turbidity by using High-salt Elution Buffer During Protein a Chromatography
Authors: - Om Narayan , - Kaushal Joshi , - Tarun Gupta , - Mayank Thakkar , - Utpal Deori , - Chandramauli Rawal
Published: June 2023

During purification of monoclonal antibodies, viral inactivation/removal step is a mandatory step to comply with the regulatory guidelines which commonly performs at low pH about 3.5 and further neutralizes it to a pH about 7.0. Neutralization of monoclonal antibodies results formation of high turbidity which is troublesome for further processing such as filtration and other chromatography processes and it eventually leads to filter clogging and increases column back pressure. In this work, we propose a new optimized process of affinity chromatography (Protein A) by using a high salt elution buffer which reduces turbidity more than 80%. A systematic study of different concentration of salts were analysed and it reveals that salt concentration greater than 100mM in Protein A elution buffer reduces turbidity during neutralization of monoclonal antibodies when compared to low salt concentration of elution buffer. We also found that elution of monoclonal antibodies during Protein A chromatography at pH 3.5 results higher reduction of turbidity compared to pH 3.0. These findings provide both cost and time effective for large scale production of monoclonal antibodies as it eliminates the use of multiple filters throughout the purification process.

Education is a kit for a person to free from the shackles of ignorance, poverty, and underdevelopment. Teachers are professional educators with the main task of educating, teaching, guiding, directing, training, assessing and evaluating students. Teaching practice is an effort to demonstrate the competence of prospective teachers in planning, carrying out learning and assessing the effectiveness of learning. This study aims to determine the urgency of teaching practice on the teaching abilities of prospective teachers. The research method is using literature study. The results of the study show that teaching practice is one of the most important, because practice means conducting real experiments and during the experiment a practitioner pays attention to the ongoing process until finally knowing something is lacking and then trying to fix it. Teaching practice is carried out as an implementation of improving the teaching and learning process in the classroom. Teaching practice is something urgent that must be carried out by every student teacher candidate, because it trains them so that they have the ability to demonstrate performance in real situations in learning activities in educational institutions in the future.Keywords: The Urgency of Teaching Practice and Teaching SkillsAbstrakPendidikan menjadi wahana agar seseorang terbebas dari belenggu kebodohan, kemiskinan, maupun keterbelakangan.
