 Abstract

Bituminous binders used in pavement construction works include both bitumen and tar. Bitumen is hydrocarbon material of pyrogenous origin, made available as by product of fractional distillation of crude petroleum. Bituminous materials are very commonly used in highway construction because of their binding and their water proofing properties. Plastic has become common man's friend. It finds its use in every field. Nearly 50% of the plastic consumed is used for packing. The most used plastic materials for packing are carry bags, cups, thermocoles and foams. These materials are manufactured using polymers like Polyethylene, polypropylene and polystyrene. The tubes and wires are made of poly vinyl chloride. These materials, once used are either thrown out or littered and ultimately get mixed with Municipal Solid Waste (MSW). As the plastic is non-biodegradable, its disposal is a problem and it causes social problems contributing to environmental pollution. Especially pollution caused by plastic is a very critical problem of the present society. In the present research work, the plastic blended bituminous mix using `Zycothermal` a chemical stabilizer is prepared by replacing optimum bitumen content with 8%, 10%, and 12% of plastic by weight of bitumen and Marshall Stability and flow values are compared with straight run bituminous mix.

 Abstract

Cardiovascular diseases (CVDs) are the foremost cause of death worldwide, covering conditions such as coronary artery disease, arrhythmias, heart failure, congenital defects, and stroke. Their development is influenced by risk factors including hypertension, diabetes, obesity, smoking, high cholesterol, sedentary lifestyle, and genetics. Traditional diagnostic tools like ECG, echocardiography, angiography, and stress testing remain common but are often costly, labor-intensive, and may not detect disease at early stages. Advances in artificial intelligence have introduced machine learning and deep learning methods as efficient alternatives for disease prediction. These models are capable of handling diverse datasets, ranging from clinical records to medical images, and can identify patterns that aid in accurate and timely diagnosis. This paper reviews CVD types, major risk factors, diagnostic methods, and previously applied ML and DL approaches, highlighting their strengths, limitations, and challenges such as data imbalance, lack of interpretability, and limited generalizability. Future research directions emphasize multi-modal data fusion, explainable AI frameworks, and improved neural network designs to build robust and clinically reliable diagnostic tools for cardiovascular diseases.

 Abstract

Introduction: Self-esteem and self-concept are vital psychological components that influence well-being, adjustment and personal development predominantly in young women. Yoga, as a mind-body practice, is more and more recognized for its psychological benefits in addition to physical health. Purpose: This study was carried out to examine the outcome of a structured six-week yoga programme on self-esteem and self-concept in young women. Methodology: Sixty female participants, aged between 18 to 23 years, were divided into two groups: 1) the Experimental Group (Gr. Y; n = 30), who practiced yoga, and 2) the Control Group (Gr. C; n = 30), who continued their usual lifestyle without yoga intervention. The Experimental Group (Gr. Y) took part in yoga training 3 times a week for 6 weeks. The training was administered for 60 minutes per session and asanas, pranayama, relaxation and mindfulness was included as activities. Demographic details of participants were documented. The measurement of the Rosenberg Self-Esteem Scale (RSES) and the Tennessee Self-Concept Scale (TSCS) were administered through Psychological questionnaire before and after the 6 week intervention. Statistical analysis was carried out with paired t-tests within each group (p < 0.05). Results: The mean baseline RSES score of Gr. Y was 22.4 improving to 26.9 after yoga intervention (t(29) = 7.70, p < 0.001). The TSCS score enhanced from 58.7 to 64.3 (t(29) = 6.13, p < 0.001). In Gr. C, RSES improved a small amount from 22.1 to 22.9 (p = 0.09), and TSCS from 59.0 to 59.8 (p = 0.28) with no significant changes. Conclusions: From the obtained result it may be concluded that 6 weeks yoga training notably enhanced self-esteem and self-concept in young women. The control group demonstrated no significant changes in this period. Yoga shows to be a valuable therapeutic tool for improving positive self-perception and psychological well-being.

 Abstract

Financial literacy plays an increasingly crucial role in shaping investor behavior, particularly within emerging markets like India where rapid financialization coexists with significant knowledge gaps. The expansion of financial markets and the proliferation of investment products have created both opportunities and risks for individual investors. This paper examines the influence of financial literacy on investor behavior, analyzing how knowledge, attitude, and decision-making skills affect market participation, risk management, and portfolio outcomes. Drawing on survey data, secondary research, and case studies of major literacy initiatives, the paper identifies patterns that highlight the role of education, digital inclusion, and behavioral control in improving financial outcomes. Findings reveal that higher levels of financial literacy correlate strongly with rational investment choices, reduced susceptibility to biases, and enhanced long-term planning. The paper concludes with policy recommendations emphasizing nationwide financial education, technology-driven learning platforms, and targeted programs for rural and marginalized investors.

 Abstract

Vegetarian diets frequently lack critical nutrients present in meat, fish, and dairy, which can lead to shortages and health problems. This research intends to fill that void by creating enjoyable and practical plant-based alternatives to junk food that are high in critical vitamins, proteins, and minerals. We will design "veggie food" that challenges the flavor and convenience of typical alternatives while encouraging appropriate nutrition through formulation optimization, sensory evaluation, and accessibility concerns. By effectively addressing this need, we intend to increase vegetarians' nutritional intake and health outcomes while also encouraging better snacking choices for everyone. Our findings open the path for a future in which plant-based alternatives provide both enjoyment and sustenance, transforming the food sector and encouraging health.

 Abstract

Axial compressors are commonly employed in airplanes because they offer a higher flow capacity per unit frontal area, are very efficient, and are easy to stage. But they are expensive, hefty, and have a low pressure ratio per stage. Radial discharge centrifugal compressors (radial compressors) have short axial lengths and can produce larger pressure ratios per stage. Both have relatively low efficiency and a bigger frontal area than axial compressors. A centrifugal compressor is made up of blades positioned so that flow enters and exits radially. Centrifugal compressors are mostly employed in airplanes, freezers, and marine applications. They can be utilized to achieve higher pressure ratios. Centrifugal compressors have impellers with main and splitter blades, which help to increase the pressure ratio. Due to the high pressure ratios achieved, a high thrust is produced, resulting in axial and radial thrusts.
