 Abstract

The severe operating conditions and requirement for highly potent and efficient electrocatalysts make the hydrogen evolution process (HER) in direct seawater electrolysis a major problem. In this work, (Mo) will be doped into a platinum-cobalt (PtCo) matrix to improve the catalytic activity of a new PtCoMo electrocatalyst for HER. The PtCoMo structure was optimized using the Atomic Simulation Environment (ASE) GUI, and its electronic characteristics were examined using Density of States (DOS) calculations with the Fermi level set to 0 eV. Minimal lattice deformation was seen in the optimized PtCoMo structure, suggesting that Mo was well incorporated into the PtCo matrix. The d-band center shifted closer to the Fermi level and the density of states near it increased, according to DOS analysis. The calculated binding energy of -2.8 eV indicates a strong interaction between Mo and the PtCo matrix, confirming the stability of the doped structure. Furthermore, the Gibbs free energy calculations demonstrated improved thermodynamic stability of PtCoMo at room temperature compared to undoped PtCo. The self-supported Pt-Co-Mo electrode presents outstanding HER activity, which only requires extremely low overpotentials of 179.2 mV and 194.1 mV to reach a large current density of 2000 mA cm-2 in 1 M KOH and 1 M KOH seawater, respectively, for overall water splitting, cell voltages down to 1.50 V and 1.51 V are necessary to drive 10 mA cm-2 in 1 M KOH and alkaline seawater, respectively.

 Abstract

Agriculture along its allied sectors, is the largest livelihood provider in West Bengal , more so in the vast rural areas. Census 2011 data reveals that majority of total rural workers are cultivators or agricultural laborers. Therefore, our State's development depends significantly upon the development of agriculture. Agriculture is demographically the broadest economic sector and plays a significant role in the overall socio-economic fabric of India. After a long period of stagnation, agricultural growth in West Bengal was initiated in the early 1980s. There has been a growing concern in recent years about the trend of agricultural output in most of the agricultural states in post-reform period since 1990. The conducive effect of implementation of New Agricultural policy enhanced the productivity in the 1980s which have been petered out in the phase of neo-liberal reforms in India. The improper use of chemical fertilizer and pesticides in technology-intensive production of rice and wheat largely account for environmental degradation and erosion of soil fertility. Under this backdrop, this article attempts to uphold the trend of major food grain and non-food grain crop production of rural West Bengal of its own as well as across the administrative division in order to understand the agricultural development in West Bengal, if any during 200-2001 to 2014-15. The study is descriptive in nature based on secondary data published in Statistical Abstract 2015. For that research purpose, Garret Ranking tool has been used.

 Abstract

Cyber-attacks represent a pervasive threat in the digital age, with perpetrators leaving behind digital artefacts that can potentially unveil their identities and behaviours. In response, forensic agencies and law enforcement departments leverage an array of digital forensic toolkits, both commercial and open-source, to examine digital evidence comprehensively. This research survey, a comprehensive and in-depth study, is a comprehensive overview of the current state-of-the-art digital forensics concepts, identifying research gaps, introducing different computer forensic domains and toolkits, and offering a comparative analysis to aid investigators in tool selection during forensic processes. It also pinpoints current challenges and suggests future research directions in computer forensics. The field of digital forensics is multidimensional, encompassing various domains such as network forensics, memory forensics, and mobile forensics. Each domain presents unique challenges and requires specialised toolkits tailored to effectively extract and analyse digital evidence. The survey, designed to provide a nuanced understanding of the forensic landscape, aims to equip investigators with a comprehensive view of these domains and the corresponding toolkits. Commercial and open-source digital forensic toolkits are pivotal in evidence acquisition, analysis, and presentation. While commercial solutions often offer comprehensive features and user-friendly interfaces, open-source toolkits provide flexibility and customisation options. Through a detailed examination of these toolkits, the survey aims to empower investigators with insights into their capabilities and limitations, enabling informed decision-making during the forensic process. Moreover, the survey includes a comparative analysis of toolkit characteristics, such as scalability, reliability, and compatibility with operating and file systems. This comparative framework, a comprehensive guide, facilitates the selection of appropriate toolkits based on the specific requirements of each forensic investigation, thereby enhancing efficiency and efficacy. In addition to providing an overview of existing digital forensic practices, the survey identifies research gaps and challenges in the field. These challenges encompass technological limitations, legal and ethical considerations, and the evolving nature of cyber threats. By acknowledging these challenges, the survey encourages further research and innovation to address emerging issues and enhance the effectiveness of digital forensic investigations. Furthermore, the survey delineates future research directions, emphasising areas such as the integration of artificial intelligence and machine learning techniques into digital forensic processes, the development of standardised procedures and protocols, and the enhancement of forensic readiness in emerging technologies such as Internet of Things (IoT) and cloud computing. In conclusion, the proposed research survey is a comprehensive tool that aims to provide a comprehensive overview of digital forensics, identifying current practices, research gaps, and challenges. By offering insights into different forensic domains, toolkits, and comparative analysis, the survey empowers investigators to navigate the complex landscape of digital evidence examination effectively. Moreover, by identifying future research directions, the survey contributes to advancing the field and developing innovative solutions to combat cybercrime.

 Abstract

Small Scale Industries (SSI) are industries that manufacture, produce and render services on a small or micro scale level The SSI is recognized as an instrument for social transformation, development of employment opportunities, providing entrepreneurship opportunities and securing dispersal of industries. Small- and large-scale enterprises are the back bone of the industrialization process of a country. Development of large scale enterprises depends upon the development of SSI units. The main aim of any business could be achieved only through a series of actions taken by the entrepreneur to market his products. The growth of any business much depends upon how efficiency they solve their marketing problems. Therefore, an attempt is made in this research to study and to highlight the important marketing problems faced by the SSI Units in the Tiruchirappalli District.

 Abstract

ABSTRACT One of the most often used natural items is essential oil, which has several uses in dermatology. A illness known as hair loss causes hair to fall out of places on the skin where it normally grows, such as the body and scalp. The natural, nontoxic, nonpollutive, and biodegradable essential oils have many medicinal uses and little chance of negative side effects. Rosemary oil has received considerable attention in hair because it is said to promote hair growth and prevent hair loss. Rosemary oil is an essential oil obtained from the rosemary plant native to the Mediterranean region. It has been used for centuries and is known for its aromatic fragrance. Rosemary oil has several beneficial properties and has been used in the folk medicine, pharmaceutical, and cosmetics industries, mainly for its antioxidant and anti-inflammatory properties, which are attributed to the presence of carnosol/carnosic and ursolic acids. The therapeutic use of rosemary has been explored for the treatment of inflammatory diseases; however, other uses have been studied, such as wound healing and skin cancer and mycoses treatments, among others. Besides it therapeutic uses, rosemary has potential applications in cosmetic formulations and in the treatment of pathological and non-pathological conditions, such as cellulite, alopecia, ultraviolet damage, and aging. This review aims to critically discuss the topical applications of rosemary found in the literature while also offering relevant information for the development of topical formulations of its bioactive compounds. Topical application is an important administration route for drugs requiring local action on the skin, thereby avoiding their systemic absorption and adverse side effects. Numerous research have proven that topically carried out rosemary oil can certainly stimulate hair regrowth and assist basic hair health. In fact, one examine even as compared its effectiveness to that of minoxidil, a usually used medicinal drug for hair loss[25].The hair growth activity, refractive index, acid value, and saponification value of hair formulations of Rosmarinius officinalis , Trigonella foenumgraecum , and Hibiscus rosasinensis , Ricinus communis , phyllanthus emblica ,Eclipta prostrata in various concentrations as herbal oil were investigated. Hair growth was observed in formulations made using a variety of oil preparation techniques and the results were admirable.

 Abstract

Introduction: Mountain trekking is a highly popular recreational activity known for its physical and mental benefits. However, it also places significant stress on the lower extremities, particularly on the tibio-femoral and patella-femoral joints. This stress can lead to injuries such as Iliotibial Band Friction Syndrome (ITBFS), which is caused by repetitive friction of the iliotibial band (ITB) against the lateral condyle of the knee. This study focuses on the prevalence and characteristics of ITBFS among trekkers, a condition often exacerbated by walking on uneven surfaces or descending slopes. Objective: The primary aim is to determine the prevalence of ITBFS in trekkers. Specific objectives include assessing the prevalence of ITBFS among both professional and recreational trekkers using the Noble compression test. Methodology: A cross-sectional observational study was conducted involving trekkers of varying levels, including professional and recreational participants. The Noble compression test was utilized to diagnose ITBFS. Additional data were collected on the participants' trekking habits, pain experiences, and the impact of ITBFS on their activities. Results: The study identified a notable prevalence of ITBFS among trekkers. The findings highlighted differences in the prevalence rates between professional and recreational trekkers. Factors such as terrain type, trekking duration, and weight carried were also explored in relation to ITBFS incidence. Conclusion: This research underscores the importance of recognizing and addressing ITBFS in trekkers. The insights gained can inform targeted interventions and preventive measures to help mitigate the risks associated with this condition, promoting safer and more enjoyable trekking experiences.
