Abstract: In this world of depleting resources, renewable energy plays an important role. Wind energy is one of the major renewable energy sources. In this paper we intend to study and review various research papers on generating electricity from wind energy using turbo ventilators. This method is economical and feasible by applying various electrical and mechanical techniques. In this paper we also intend to improve the efficiency of the system by using various materials for the fabrication of turbo ventilators. We have reviewed the papers on this topic published by various authors. We have compared their designs and concluded into an efficient model by combining all the designs into one. Turbo ventilators are widely used on industrial sheds and warehouses for natural ventilation without consuming electrical energy. They operate on the principle of wind velocity and stack effect, where hot air rises and rotates the turbine blades. The present project explores the potential of utilizing this otherwise wasted rotational energy of turbo ventilators for generating electricity. The working concept involves coupling the rotating shaft of a turbo ventilator with a low-rpm DC generator or alternator through a suitable gear mechanism. As the ventilator rotates due to wind or thermal convection, mechanical energy is converted into electrical energy. The output is generally low voltage DC, which can be stored in batteries using a charging circuit and later used for small-scale applications like LED lighting, mobile charging, or powering sensors.The study includes design considerations such as selection of generator, gear ratio optimization, mounting arrangement, and electrical load calculation. Experimental results show that a standard 24-inch turbo ventilator can generate 5V–12V under moderate wind speeds of 3–6 m/s, producing power in the range of 3–10 W. Though the output is small, it is continuous and free of cost, making it suitable for sustainable energy harvesting. In conclusion, electricity generation from turbo ventilators provides a cost-effective and eco-friendly solution for auxiliary power needs in industries. It utilizes existing infrastructure, requires low maintenance, and contributes to green energy initiatives. The concept can be further improved by using efficient generators, MPPT circuits, and multiple units in parallel for higher output.

Abstract: The improper disposal of menstrual waste has become a major concern due to its impact on hygiene, public health, and environmental sustainability [1][3][4]. Conventional disposal methods such as open dumping, flushing, or mixing sanitary waste with regular garbage can lead to pollution, unpleasant odor, and difficulties in waste management [3][5]. To overcome these challenges, this work presents a compact and energy-efficient menstrual waste disposal system designed to provide safe, hygienic, and automated waste handling with minimal human intervention [7][8]. The proposed system is developed using an ESP32 microcontroller that controls the heating, cooling, and monitoring operations of the disposal unit. When menstrual waste is inserted into the chamber and the start button is pressed, a relay-controlled nichrome heating element generates sufficient thermal energy for effective incineration [1][7]. A DHT11 temperature sensor continuously monitors the chamber temperature and transfers the readings to the controller for safe operation. After completion of the burning process, a cooling fan is automatically activated for a predefined duration to reduce the internal temperature of the system. In addition, a 2×16 LCD module displays real-time temperature values and cooling fan status, improving system usability and monitoring capability. The experimental results demonstrate that the proposed system provides reliable operation, efficient waste disposal, and reduced direct human contact with sanitary waste [6][9]. The compact design and automated functionality make the system suitable for deployment in homes, schools, hostels, hospitals, and public sanitation facilities. By integrating automation, thermal processing, and smart monitoring features, the proposed system contributes toward environmentally responsible menstrual waste management and improved sanitation practices [2][5][10].

Abstract: The chocolate is most loving food of children where as the medicine is the hating substance. So, objective of this study was to formulate the chocolate that contain drug i.e., medicated chocolate to prevent the disease. In children cough, viral infection is most common diseases. Dark chocolate gets popularity for several decades due to its enormous health benefits. Dark chocolate is considered a functional food due to its anti-diabetic, anti-inflammatory, and anti-microbial properties. It also has a well-established role in weight management and the alteration of a lipid profile to a healthy direction. Multivitamins are used to provide vitamins that are not taken in through the diet.Multivitamins are also used to treat vitamin deficiencies (lack of vitamins) caused by illness, pregnancy, poor nutrition, digestive disorders, and many other conditions. Antioxidant-the word itself is magic. Using the antioxidant concept as a spearhead in proposed mechanisms for staving off so-called "free-radical" reactions, the rush is on to mine claims for the latest and most effective combination of free-radical scavenging compounds. We must acknowledge that such "radicals" have definitively been shown to damage all biochemical components such as DNA/RNA, carbohydrates, unsaturated lipids, proteins, and micronutrientssuch as carotenoids (alpha and beta carotene, lycopene), vitamins A, B6, B12, and folate. Defense strategies against such aggressive radical species include enzymes, antioxidants that occur naturally in the body (glutathione, uric acid, ubiquinol-10, and others) and radicalscavenging nutrients, such as vitamins A, C, and E, and carotenoids.

Abstract: The rapid growth of the tourism industry has increased the need for efficient travel package design that minimizes operational expenses while maintaining customer satisfaction. Travel agencies and tour operators frequently face challenges in selecting transportation modes, accommodation facilities, sightseeing locations, and scheduling activities within a limited budget. This study proposes a cost minimization model for designing an optimal travel package using Operations Research techniques. A linear programming framework is developed to determine the best combination of travel services while satisfying constraints related to budget, travel time, accommodation capacity, tourist preferences, and resource availability. The proposed model integrates transportation costs, lodging expenses, meal charges, and attraction fees into a unified optimization framework. Numerical experiments demonstrate that the model significantly reduces total travel expenditure compared with traditional package planning methods. The study contributes to tourism operations management by providing a scientific decision-support tool capable of assisting travel agencies in creating economically efficient travel itineraries. The findings indicate that optimization techniques can improve profitability, enhance resource utilization, and increase customer satisfaction through systematic travel planning.

Abstract: The exponential growth of the Android ecosystem has been accompanied by a surge in sophisticated mobile mal-ware. Traditional signature-based detection mechanisms struggle to keep pace with these evasive threats, necessitating more adaptive and intelligent defense strategies. In this paper, we present a novel hierarchical ensemble Convolutional Neural Network (CNN) framework designed for robust Android malware detection. By transforming APK bytecode into grayscale images, our approach bypasses conventional manual feature engineering and leverages spatial pattern recognition. The proposed archi-tecture integrates three distinct deep learning models—ResNet50, DenseNet121, and VGG16—to extract diverse and comprehensive feature representations. The framework operates in two stages: initially classifying applications as benign or malicious, and subsequently categorizing the malicious samples into 25 distinct malware families. Experimental evaluations demonstrate that our ensemble approach achieves a high accuracy of 89.15%, out-performing individual CNN baselines. Furthermore, this image-based learning paradigm proves highly resilient to common structural obfuscation techniques utilized by modern Android malware.

Abstract: Inflammation is a natural protective response of the body against harmful stimuli such as infection, injury, toxins, and tissue damage. Although it plays an important role in healing and defense mechanisms, prolonged or chronic inflammation may lead to severe tissue damage and various disease conditions. Conventional anti-inflammatory drugs such as NSAIDs and corticosteroids are widely used for the management of inflammation; however, their long-term use is associated with several adverse effects including gastric irritation, renal toxicity, and cardiovascular complications. Due to these limitations, there is an increasing demand for safe, effective, and natural alternatives in the form of herbal formulations. The present study focuses on the formulation and evaluation of a herbal anti-inflammatory oil using Annona reticulata leaves extract along with turmeric, ginger, sesame oil, eucalyptus oil, mentha piperita oil, and vitamin E. Annona reticulata is rich in bioactive phytoconstituents such as flavonoids, alkaloids, tannins, and phenolic compounds which contribute to its anti-inflammatory and antioxidant activities. Turmeric provides curcumin, while ginger contains gingerols and shogaols, both of which are known for their strong anti-inflammatory properties. The essential oils included in the formulation enhance skin penetration, provide soothing effects, and improve overall therapeutic action. The formulated herbal oil was evaluated for various physicochemical parameters such as appearance, odor, pH, viscosity, spreadability, homogeneity, skin irritation, and stability. The results indicated that the formulation was stable, safe for topical application, and showed satisfactory characteristics. The synergistic effect of all herbal ingredients may contribute to effective reduction of inflammation with minimal side effects. Hence, the developed herbal oil formulation can be considered a promising, safe, and economical alternative for the management of inflammatory conditions.{1}

Abstract: The current trend shows a significant increase in the application and use of sheet metal in manufacturing processes. Stainless steels are selected for dairy applications because they are resistant to corrosion, inert, easily cleaned and sterilized without loss of properties, and can be fabricated by a variety of techniques into robust structures. For this study, Austenitic Stainless Steel (ASS) 304material was selected and cut into circular shapes of varying diameters but with thickness of 1mm and 0.8mm. These circular cut materials are referred to as blanks. Before testing,a lubricant(grease)is applied to the blanks.The blanks are then subjected to as with cup drawing test using a hydraulic deep drawing press to determine the limitingdrawingratio(LDR). During the deep drawing process, the cup is formed by the punch force. At a certain blank diameter, the bottom of the cup may fracture due to the punch force. The diameter of the blank just before the fracture occurs represents the maximum. diameter of the blank.The addition of lubricant helps to analyze the impact of friction between the blank and the punch during the deep drawing process. The drawability of sheet metals is measured in terms of the LDR, which indicates the maximum deformation a cup can undergo without failure using a hydraulic press. The LDR is defined as the ratio of the maximum diameter of the blank to the diameter of the punch. Experiments were conducted on ASS 304 sheets using a hydraulic press deep drawing setup, and load-element were generated. The LDR value for 304 sheets was determined.
