 Abstract

Solar distillation is a promising method for desalinating saline water that can partially fulfill humanity's need for freshwater, requiring only simple technology and clean energy. Solar distillation systems have shown to be effective when weather conditions are favorable and the demand is not too high. However, low daily productivity of such systems has been a challenge, leading scientists to investigate ways to improve still productivity and thermal efficiency to reduce water production costs. This paper provides an overview and technical assessment of the latest developments in single and multi-effect solar stills, including still configurations, operational challenges, and environmental impacts.

 Abstract

The specific objective is to prove the existence and uniqueness of the solution of the proposed PDE. The existence and uniqueness of the solution have been proved. To demonstrate the existence of the solution, the Fourier transformation was used. The variational formulation was used to prove the uniqueness of the solution. The combination of the Fourier transformation and the variational formulation yielded the expected results: the existence and uniqueness of the solution.

 Abstract

Agriculture is vital to the Indian economy, yet recent shifts have caused a crisis in the sector. To address this, the research aims to make agriculture profitable by using machine learning, bridging agriculture with technology, and deep learning. By predicting suitable crops based on climate and historical data, farmers can make informed decisions. An accompanying web application integrates features like crop recommendations, fertilizer guidance, disease detection, yield forecasting, and user feedback. This holistic approach revitalizes agriculture by leveraging modern technologies and data-driven insights. By bridging agriculture with technology and deep learning, the study aims to user in sustainable and profitable farming practices in India, ensuring the sector's resilience and growth.

 Abstract

The adoption of solar energy is increasing rapidly worldwide due to its renewable and eco-friendly nature. However, the efficiency of solar panels can be significantly impacted by dust, debris, and other environmental factors. To address this issue, an automated solar panel cleaning system is proposed. This system utilizes a combination of sensors, actuators, and a control unit to autonomously detect the level of dirt on solar panels and initiate cleaning operations accordingly. The system employs techniques cleaning the system automatically when the voltage of the panel falls beyond certain limits of the threshold voltage by using different equipments which in term makes this automation successful.This cleaning mechanism that we are developing only allows the cleaning of the panel only for one time in a day because simultaneous cleaning of the system requires more energy which leads to losses. By automating the cleaning process, the system reduces manual labour, ensures consistent cleaning intervals, and maximizes the energy output of solar installations. Additionally, it contributes to prolonging the lifespan of solar panels and minimizing maintenance costs. This abstract highlights the significance of automated cleaning systems in enhancing the performance and longevity of solar energy systems, ultimately promoting the widespread adoption of renewable energy sources.

 Abstract

Although millions of people use the bicycle every day, the design of the modern bicycle is still largely traditional, and comparatively little research work has been carried out to determine the design which is most effective physiologically. New modifications have generally been tested on the racing track where, however, many uncontrollable factors may influence the result. From both the practical and physiological point of view it is important to determine the energy output when riding different types of bicycles for a given distance at a certain speed. In our work modification of treadmill is done to better fit the requirements of users. Treadmill bicycle is designed for those humans who love to run outside. Treadmill equipped on bicycle frame and formulates a big innovation named 'Treadmill bike'.This bicycle runs perfectly on human momentum. As the rider walks on the treadmill, the belt butts up against the rear wheel propelling the bike forward. Treadmill bicycle is designed for runners as the ideal treadmill device, this device combines the best exercise running and cycling to deliver a low-impact, high performance workout outdoors. We believe it is the ideal device for healthy runners. It delivers an exercise experience that is closer to running than anything else available today.

 Abstract

Matricaria chamomilla L.(Asteraceae) is a famous medicinal herb and it is sold all over the world. Traditional medicine uses it extensively to treat a wide range of illnesses, including infections, neuropsychiatric, respiratory, gastrointestinal, and liver ailments. Additionally, it has calming, antispasmodic, antibacterial, and antiemetic properties. Reports on the taxonomy, description of the botanical and ecological environment, ethnomedical applications, phytochemistry, biological and pharmacological properties, potential industrial applications, and encapsulation of M. chamomilla were thoroughly compiled and summarised in this review. On the other hand, phenolic substances such as phenolic acids, flavonoids, and coumarins predominated in M. chamomilla extracts. M. chamomilla also displayed several biological traits, including antioxidant, antibacterial, antifungal, anti-parasitic, insecticidal, anti-diabetic, anti-cancer, and anti-inflammatory actions. The biological activity of M. chamomilla can be improved, as well as its applications, by encapsulating the plant's essential oils or extracts. The results show that M. chamomilla's pharmacological actions support its traditional applications. The essential oils and extracts from M. chamomilla did indeed exhibit intriguing antioxidant, antibacterial, antifungal, anticancer, antidiabetic, antiparasitic, anti-inflammatory, antidepressant, antipyretic, anti-allergic, and analgesic effects. The medical use of M. chamomilla on people and animals was also its most significant use.

 Abstract

Owing to the varied biological activities exhibited by the nitrogen bases like pyridine (Py), imidazole (Im) and methylimidazole (MeIm) the kinetic study for the reactions of PSAA with H2O2 catalysed by the different oxovanadium(IV)-salophen complexes were carried out in the presence of nitrogen bases like Py,Im and MeIm. The reactions were monitored spectrophotometrically in 100 % acetonitrile medium under pseudo first-order conditions with excess of [PSAA] over the oxidant and complex concentrations. Kinetic study reveals the rate of the reaction increases with increase in concentration of the complex and hydrogen peroxide whereas the rate of the reaction is strongly retarded by all the three bases.

 Abstract

There is a significant health burden due to the rising incidence of diabetes mellitus and its related health problems. Preventing and controlling this disease will mostly depend on raising awareness of it. Additionally, poor glycemic control brought on by noncompliance with the management increases the risk of dangerous consequences. The current study was carried out to gauge medication adherence and gauge patients with Type 2 diabetes's awareness of diabetes from a variety of perspectives. In this research, we use a pie diagram to explain the age distribution of respondents based on their knowledge of their diabetes and symptoms.

 Abstract

S?ri?vidya mantra is very secretive, therefore none of these secrets can be learned by reading books. S?ri?vidya mantras are to be understood and attained by the guru himself. S?ri?vidya Upa?sana uses many mudra?s, some of which are also found in the Kerala Tantra system. Mudra?s and their applications differ from Tantra according to the differences in pu?javidhi. S?ri?vidya Upa?sana is a very great ritual that cannot be written in one article, so this article mostly describes the mudra?s used in S?ri?vidya Upa?sana and the rituals associated with it only. In S?ri?vidya Upa?sana, S?ricakra, Mantra, and Devi, these three are the same. All deity spirits and yantras are embodied in Sri?cakra. Sri??cakra svaru?pam? is emanating from the center as Bindu, Trikon?am, As?t?akon?am, Andhardas?akon?am, Caturdas?akon?am, As?t?adalam, S??odasadalam, Vrithatrayam, Bhu?puratrayam, etc. Ten Mudra?devi?s are located on the third line of Bhu?puram. Each of the Mudra?devi?s has its own set of mudra?s. These mudra?s are called Das?a Maha?mudra?.
