Hemchandra Goswami’s Beloved’s Letter and William Shakespeare’s Sonnet 116: A Comparative Analysis
Authors: - Gayatri Goswami
Published: March 2024

Hemchandra Goswami (1872-1928), representing a vibrant voice- being one amongst the Romantic-trio of Jonaki Era of Assamese literary world establishing a new spirit and William Shakespeare (1564-1616), the greatest dramatist and poet of the Elizabethan Age of British literary world predicate ample scope to investigate exploring various literary aspects though belonging to diverse world spatially and temporally. So, here in this research paper it is endeavoured to make a comparative analysis of the two poets considering chiefly the dominant thematic aspect of love along with stylistic aspects characterizing the poetic world of both the poets like style and form with reference to the two specific poems Hemchandra Goswami’s Priyotomar chithi translated as The Beloved’s Letter and Shakespeare’s Sonnet 116. The passion of love emanates from human heart as spontaneous expression and therefore its literary manifestation is very obvious in any genre of literature-whether it is poetry, novel, drama, short story or any other. The theme of love has a universal appeal- from temporal point of view, this theme is found in the creations of any age as well as its prominence in the creations of all literary manifestations irrespective of space such as in British, American, Indian, Assamese etc. Moreover, Hemchandra Goswami’s The Beloved’s Letter is regarded as the first Assamese sonnet and Shakespeare’s sonnets have always been widely acclaimed and acknowledged as the classic creation. So, understanding of the two sonnets belonging to diverse space and time would be an impelling force to negotiate the ideas impartially and scientifically which may have a substantial bearing on the existing knowledge. Thus, this paper is an attempt to make a comparative analysis of these two literary stalwarts exploring the literary realm of Hemchandra Goswami and William Shakespeare particularly taking into account The Beloved’s Letter by Hemchandra Goswami and Sonnet 116 by William Shakespeare.

Large numbers of bricks are required to meet the needs of increasing population for both residential and commercial sectors. The overall development and industrial development lead to the use of the traditional bricks at a very hefty rate. The traditional bricks are commonly made up of clay as its main component as a result it is on the verge of exhaustion. To standardize its broad, utilize and discovering its auxiliary one is the need of the hour. In this study, bricks were made by using different proportions of alternative materials like fly ash(FA), sand, lime and plaster of Paris . The size of sample 220×130×900 mm was manufactured and quality constraints like compressive strength and water absorption were tested at different curing ages. The cost-effective mix design of the bricks for optimum compressive strength and rate analysis was also the part of this study. It was detected from the observation of results that the compressive strength decreases with increasing percentage in fly ash and increases with increasing percentage of sand and lime in fly ash-based bricks. Increment in water absorption was observed as fly ash content is increased and decrement of water absorption is seen with increasing percentage of sand and lime in fly ash-based bricks.

Authors: - Ms Nivedita R D , - Dr. Sumana MN , - Mr Keerthi S Gowda , - Dr. Archana Hegde M
Published: March 2024

Enteric fever is a major health concern worldwide, especially in tropical countries. Enteric fever caused by Salmonella enterica is a gastrointestinal tract disease to begin with and later involving many systems,. After the advent of multidrug resistant Salmonellae, ciprofloxacin became the focus of its treatment. Azithromycin is widely being used for the prevention and treatment of Enteric fever. Of late, there are reports in literature to support that Salmonella have regained susceptibility to Ampicillin, Cotrimaxazole and Chloramphenicol. Therefore, this study undertaken aims to find out the antimicrobial susceptibility of Salmonella isolates to conventional drugs like Ampicillin, Cotrimaxazole and Chloramphenicol and find out susceptibility pattern of Ciprofloxacin that is over used for treatment of enteric fever and Azithromycin, most often used in children. As there is no disc diffusion method as per CLSI 2019 guidelines to detect the susceptibility to ciprofloxacin, ciprofloxacin resistance was determined by minimum inhibitory concentration(MIC)by E-test.Kirby-Bauer disk diffusion technique was used to monitor Azithromycin resistance among Salmonella entericaserovarTyphi as per CLSI 2019 guidelines.
METHODS:The Prospective study was conducted over a period of 8 months (May 2019- December 2019) with the clinical samples yielding the growth of Salmonella from blood. These strains were screened for Ciprofloxacin susceptibility by E-test. Azithromycin,Ampicillin, Co-Trimaxazole and Chloramphenicol susceptibility were detected by Kirby-Bauer disc diffusion technique.
RESULTS: Of the 80 isolates that were screened, 52 (65%) were resistant, 24 (30%) were intermediate susceptible and remaining 4(5%) were sensitive to ciprofloxacin by MIC detection. 69 (86.25%) of the isolates were sensitive and 11 (13.75%) were resistant to Azithromycin by disc diffusion technique. All isolates (100%)were found to be susceptible to Ampicillin, Co-Trimaxazole and Chloramphenicol
CONCLUSION:The current study shows a high prevalence of resistance to ciprofloxacin in Salmonella species isolated in and around Mysuru district in southern India. Detection of ciprofloxacin resistance by the Kirby Bauer disk diffusion method is less effective, so it is advised that MIC of ciprofloxacin must be regularly done in the diagnostic laboratories for all strains. The findings from our study also showed low level resistance (13.75%) to Azithromycin. It is advised that Azithromycin can be used as a therapeutic agent only if it is reported to be sensitive by the susceptibility test. Conventional agents like Ampicillin, Co-Trimaxazole and Chloramphenicol can be reconsidered for treatment of Enteric fever.

Comparative Studies Between Lattice Dynamical Study and Normal Coordinate Analysis of HTSC EuBa2Cu3O6
Authors: - SONAMUTHU.K , - GEENA VIDYA.S
Published: March 2024

It is generally believed, that is needed to sign post the way to the development of materials with high critical temperature, even to room temperature and above, is the formulation of a proper theoretical understanding of superconductivity in these materials. Many experimental studies suggest an intimate relationship between phonons, and the superconducting transition in the high Tc oxides.For example, Raman frequencies and line widths, elastic constants and thermal conductivity all show changes around Tc. Nevertheless, there is not a well- developed theory to explain how the phonons are related to Tc.. In conventional superconductors, the role of phonons is well established. However, in high Tc superconductors, the role played by phonons is controversial. Even if they do not mediate the pairing mechanism, they are likely to play an important subsidiary role. Hence there is much interest in the phonon structure of these materials.
The normal state and superconducting properties are believed to arise from the strongly correlated motion of the electronic charge carries (electrons or holes) in the CuO2 planes that essentially define the layered cuprate HTSC. The other cations and oxygen atom in the structure provides structural stability and control the number of charge carries in the CuO2 planes.
The Raman spectroscopy of HTSC explains that the role played by the phonons in the mechanism of superconductivity in the perovskite family of superconductors is not fully understood although a large series of experimental results has shown considerable coupling of some phonons to electronic excitation in these systems. Optical spectroscopy and especially Raman and Infrared spectroscopy revealed strong direct influences of the changes in the electronic states to the phonon at the center of the Brillouin.

RESEARCH ON IMPROVING THE GATE VALVE OF THE DRILLING MANIFOLD
Authors: Zuleikha Eyvazova, Andrey Luzhanski Zuleikha Eyvazova, Andrey Luzhanski
Published: March 2024

The article considers the possibility of improving the design of the valve of the drilling manifold, which is used to cool the rock-crushing tool, as well as for the constant removal of drilled rock (sludge) from the well. Currently, in existing drilling manifolds designed for pressures up to 45 MPa, the most used are towed valves or valves with a quick-release connection (BRS) to the pipeline. At higher pressures, gate valves of the Z43Y type with a flange connection are used, the design of which is like the design of direct-flow gate valves used for fountain fittings. Since these connections are used to reduce the time for changing gate valves in order to repair or clean them, there is a need to improve the design of the locking assembly of these valves, designed for higher pressures to increase the tightness of the gate and ensure a high degree of maintainability of the gate valve. In order to improve the gate valve of the drilling manifold, it is proposed to change the design of the locking unit, which provides reliable sealing, ensuring ease of installation of the gate assembly. In this case, the gate is assembled, consisting of two halves, in which slots are provided for installing disc springs in them. The ends of each of the gate halves have bevels for ease of assembly of the locking assembly.
Keywords: drilling pump, manifold, gate valve, quick-release connection, tow joint.

Published: March 2024

Os incêndios florestais apresentam efeitos adversos ao planeta, como fragmentação florestal, perda de biodiversidade, poluição do ar e ameaça Ã  vida e Ã  saúde humana. No entanto, a ecologia do fogo atesta que o fogo é também um evento ecológico, dinâmico e indispensável para a sobrevivência de determinados ecossistemas. Devido a essa ambiguidade, esta revisão teve como objetivo sintetizar informações técnicas, literárias e científicas que auxiliem no entendimento das relações entre os ecossistemas e os incêndios florestais. Assim, foram abordados assuntos diretamente ligados Ã  ecologia do fogo, como a dinâmica dos regimes de fogo, o comportamento do fogo, a relação entre os incêndios florestais e as emissões de carbono no Brasil. Mediante as informações compiladas, percebe-se que o fogo é indispensável para a sobrevivência de muitas fitofisionomias brasileiras existentes, principalmente no Cerrado, Pantanal e Pampa. Uma série de adaptações de espécies vegetais presentes em ambientes influenciados pelo fogo foram apresentadas. Também foi investigado o papel das variáveis no comportamento do fogo e como os incêndios estão relacionados Ã s alterações climáticas. Estima-se que queimas não associadas ao desmatamento totalizaram 3,16 GtCO2 de emissões imediatas entre 1990 e 2020, sendo um dos principais contribuintes para emissão de gases de efeito estufa. Diante desse contexto, esta revisão ressalta a importância do desenvolvimento de políticas públicas para efeitos de curto e longo prazo de maneira a popularizar a conservação e o uso sustentável do fogo em ecossistemas propensos a ação dele.
Estimating Willingness to Pay for Dementia Prevention and Policy Implications
Authors:   Taegu Science University Defense Security Institute, Kim Yong Joo
Published: March 2024

In Korea, the social cost of dementia is rapidly increasing due to rapid aging. This study estimates the public's willingness to pay(WTP) for dementia prevention, to provide policy implications for dementia management. Using contingent valuation method(CVM), the average per capita WTP amount for dementia prevention was estimated to be KRW 80,955,973. As a result, the social cost of preventing as many dementia patients as in 2021 turned out to be KRW 78.7245 trillion. The cost of dementia incurred during the lifespan of dementia patients was KRW 205.378 trillion, 2.6 times higher than the prevention cost. The difference between the cost of dementia and prevention cost is expected to expand rapidly over time. In particular, the cost of dementia for elderly patients in 2060 was estimated to be KRW 1,630 trillion during their lifetime, 5.8 times greater than the prevention cost of KRW 280 trillion. In addition, due to the low fertility rate in Korea, the burden of costs for elderly dementia patients among the working-age population was estimated at KRW 13.29 million per person per year. In the future, the cost of dementia, thus the gap with prevention costs, is espected to increase rapidly. In particular, the social costs for the families of dementia patients are huge and the burden of supporting elderly dementia patients in the working-age population will increase. This study concludes prevention of dementia is more important than ex post management. As policy recommendations, this study emphasized the importance of people’s cooperation and the connection of related policies to respond to the dementia problem by giving several examples.

Published: March 2024

Although student councils are known to be vital in assisting school administration in management of student discipline, their presence in leadership has not fully controlled cases of student indiscipline. This study sought to examine the influence of student councils’ socio-demographic dynamics on management of secondary school students’ discipline in Kenyenya Sub-County, Kenya. The study was based on the Social Cognitive Learning Theory (SCLT), Trait Theory of Leadership (TTL) and the Red-Hot-Stove Theory (RHST) and employed descriptive survey design. The study utilized interview guide designed for SCDE to collect primary data. There were questionnaires for principals, deputy principals, teachers and Student Council Leaders (SCL) to collect both qualitative and quantitative data. A sample size of one hundred and twenty-six (126) respondents corresponding to thirty per cent (30%) of the target population (422) was used to select 13 principals, 13 deputy principals, 86 teachers and 13 students’ council leaders. This study adopted a multi-stage sampling approach where stratified sampling was used to select schools while simple and purposive sampling was used to select respondents. The data was analysed based on the study objectives. Descriptive statistics were used to analyse quantitative data and the results were presented in form of frequencies, percentages, means, and standard deviations using tables, graphs, and charts. Qualitative data were analysed thematically based on the research objectives. The findings of this study indicate that the selected student councils’ socio-demographic dynamics had infinitesimal influence on management of student discipline. The study therefore recommended that the ministry of education develop policies on how learners will vet their council leaders focusing on their selected leadership dynamics

Many natural disasters, such as cyclones, typhoons, mudslides, and tsunamis, are currently plaguing the world. These tragedies, which have destroyed the coastal settlements, claim a great number of lives each year. The characteristics and structure of the Mangrove tree have the significant impact on protecting the coast from heavy wind, floods, mudslides, and other kinds of natural disasters. This research work investigates how Mangroves can protect the area near the coast from a fluid dynamics point of view. Complex real world problems require intelligent systems that combine knowledge and techniques. Hence Computational Fluid Dynamics (CFD) technique namely the finite volume method is employed as a tool in this study. In this research, a model Rhizophora Mangrove tree from Pichavaram Mangrove forest, Tamilnadu, India is generated using Ansys Workbench design modeler. A computational domain is created around this tree to reduce the boundary effect. Grid-independent research was carried out using various mesh sizes to determine the best grid resolution for the analysis. An unstructured triangular mesh was generated for the simulation. The focus of this study is to determine the 3D flow around the tree in order to determine the wind velocity, as well as the coefficient of drag and drag force on the wall tree. This research helps to give a clear understanding of wind flow around the 3D Rhizophora Mangrove tree. The velocity profile, pressure distribution, drag force, and drag coefficient around the tree are captured, analysed, and presented in detail. The results show that the Rhizophora mangrove trees can significantly reduce the flow velocity of the wind and will be able to safeguard the coast and communities nearby from natural disasters.

The Pakistan Society for the Study of Liver Diseases (PSSLD) and PKLI & RC jointly organised this meeting. This effort was based on a comprehensive literature review to establish national practice guidelines for hilar cholangiocarcinoma (hCCA). The consensus was that hCCA is a complex disease and requires a multidisciplinary team approach to best manage these patients. This coordinated effort can minimise delays and give patients a chance for curative treatment and effective palliation. The diagnostic and staging workup includes high-quality computed tomography, magnetic resonance imaging, and magnetic resonance cholangiopancreatography. Brush cytology or biopsy utilizing endoscopic retrograde cholangiopancreatography is a mainstay for diagnosis. However, histopathologic confirmation is not always required before resection. Endoscopic ultrasound with fine needle aspiration of regional lymph nodes and positron emission tomography scan are valuable adjuncts for staging. The only curative treatment is the surgical resection of the biliary tree based on the Bismuth-Corlette classification. Selected patients with unresectable hCCA can be considered for liver transplantation. Adjuvant chemotherapy should be offered to patients with a high risk of recurrence. The use of preoperative biliary drainage and the need for portal vein embolisation should be based on local multidisciplinary discussions. Patients with acute cholangitis can be drained with endoscopic or percutaneous biliary drainage. Palliative chemotherapy with cisplatin and gemcitabine has shown improved survival in patients with irresectable and recurrent hCCA.

BACKGROUND

Although chronic erosive gastritis (CEG) is common, its clinical characteristics have not been fully elucidated. The lack of consensus regarding its treatment has resulted in varied treatment regimens.

AIM

To explore the clinical characteristics, treatment patterns, and short-term outcomes in CEG patients in China.

METHODS

We recruited patients with chronic non-atrophic or mild-to-moderate atrophic gastritis with erosion based on endoscopy and pathology. Patients and treating physicians completed a questionnaire regarding history, endoscopic findings, and treatment plans as well as a follow-up questionnaire to investigate changes in symptoms after 4 wk of treatment.

RESULTS

Three thousand five hundred sixty-three patients from 42 centers across 24 cities in China were included. Epigastric pain (68.0%), abdominal distension (62.6%), and postprandial fullness (47.5%) were the most common presenting symptoms. Gastritis was classified as chronic non-atrophic in 69.9% of patients. Among those with erosive lesions, 72.1% of patients had lesions in the antrum, 51.0% had multiple lesions, and 67.3% had superficial flat lesions. In patients with epigastric pain, the combination of a mucosal protective agent (MPA) and proton pump inhibitor was more effective. For those with postprandial fullness, acid regurgitation, early satiety, or nausea, a MPA appeared more promising.

CONCLUSION

CEG is a multifactorial disease which is common in Asian patients and has non-specific symptoms. Gastroscopy may play a major role in its detection and diagnosis. Treatment should be individualized based on symptom profile.

BACKGROUND

Pancreatic ductal adenocarcinoma (PDAC) is a highly fatal disease with limited effective treatment especially after first-line chemotherapy. The human epidermal growth factor receptor 2 (HER-2) immunohistochemistry (IHC) positive is associated with more aggressive clinical behavior and shorter overall survival in PDAC.

CASE SUMMARY

We present a case of multiple metastatic PDAC with IHC mismatch repair proficient but HER-2 IHC weakly positive at diagnosis that didn’t have tumor regression after first-line nab-paclitaxel plus gemcitabine and PD-1 inhibitor treatment. A novel combination therapy PRaG 3.0 of RC48 (HER2-antibody-drug conjugate), radiotherapy, PD-1 inhibitor, granulocyte-macrophage colony-stimulating factor and interleukin-2 was then applied as second-line therapy and the patient had confirmed good partial response with progress-free-survival of 6.5 months and overall survival of 14.2 month. She had not developed any grade 2 or above treatment-related adverse events at any point. Percentage of peripheral CD8+Temra and CD4+Temra were increased during first two activation cycles of PRaG 3.0 treatment containing radiotherapy but deceased to the baseline during the maintenance cycles containing no radiotherapy.

CONCLUSION

PRaG 3.0 might be a novel strategy for HER2-positive metastatic PDAC patients who failed from previous first-line approach and even PD-1 immunotherapy but needs more data in prospective trials.
Theoretical Justification of the Holding Power of a Mobile Anchor for Holding Timber-Rafting Objects

Exploitation of small and medium-sized rivers for wood transportation ensures the economic availability of wood raw materials located at a great distance from consumers. Short-term operation of timber rafting facilities and their movement from one place to another is typical for these rivers. At such facilities, the use of mobile fillable anchors is considered to be the most appropriate. The article provides a brief description of their design, installation and dismantling. The fabrication and effective application of such anchors requires appropriate justification of their parameters (the holding power, in particular). The purpose of this study is to develop the scientific basis for determining the holding power and effective application of these anchors. A theoretical justification for the process of interaction of the proposed anchor with the soil mass has been carried out. On the basis of this justification, two alternative formulas were obtained to determine the holding power provided by one section of the grouser. Calculations using these formulas give similar results. The dependences of the holding power on the determinants, such as the vertical load on one section of the grouser transmitted from the containers being filled, the coefficient of friction of the anchor material on the soil, the density of the soil, the coefficient of its internal friction and the depth of penetration of the grousers into the soil are approximately the same. Similar properties of these formulas allow to consider them reliable. The total holding power of the anchor is calculated according to the weight of the filled containers, the holding power of one section of the grouser and their number. The degree and nature of the influence of the determinants on the holding power of a mobile fillable gravity anchor have been established. An increase in any of them leads to an increase in the holding power. The most significant determinant is the vertical load on one section of the grouser. The dependence of the holding power on it is linear. To a lesser extent, in descending order, the angle of the internal friction of the soil, the coefficient of friction of the anchor material on the soil, and the density of the soil influence the holding power. The dimensions of the grouser and their change have little effect, but the very fact of their presence provides a sizeable proportion of the holding power of the anchor.

The analysis of the current state of the process of betulin extraction from birch bark has shown the relevance of the implementation of periodic extraction technology using toluene as a solvent at small enterprises of the timber industry complex. This article presents the scheme of an extraction plant consisting of an extractor, an evaporator, a condenser, a florentine flask, an extract collector, as well as the principle of the plant operation. The extraction process is carried out in two stages: when the raw material is at rest in relation to toluene and when the raw material is extracted by continuous feeding of fresh extractant. The engineering procedure for calculating the extractor has been developed, allowing to determine its overall dimensions (diameter and height) and the duration of individual stages of the extraction process. The duration of the first stage has been calculated by solving Fick’s differential equation of mass conductivity under boundary conditions of the first kind. The duration of the second stage has been calculated considering the fact that betulin extract is continuously withdrawn from the extractor and fresh extractant is injected. In the latter case, the betulin content in the extractant varies not only in time, but also with the height of the extractor. The developed mathematical description and subsequent modeling made it possible to obtain the calculated curves of betulin distribution in birch bark at different points in time, as well as to compare the experimental and calculated data on the kinetics of the average betulin content in birch bark and toluene for each stage. Meanwhile, the kinetic curves of the average betulin content in birch bark at the second stage are presented for different heights of the extractor. It has been established that the optimal duration of the first stage is 20 min, and with the continuous feeding of fresh extractant with a flow rate of 22.5 kg/h at the second stage, the process speed increases by 6 times. This significantly reduces the total extraction time under the specified process parameters. The necessity for the introduction of the third stage (the stabilization period of the betulin content over the layer height and the cross– section of particles) has been shown.
