Future airfields will become increasingly intrigued with unmanned aerial vehicles (UAVs) due to their versatility. These robots can conduct a multitude of tasks, including carrying out strategic reconnaissance, offering telecommunications links, and aiding in metrological research, as well as finding and mapping resources, detecting forest fires, monitoring natural disasters, and defending borders, to name a few. When UAVs fly at low altitudes, they usually have multiple abilities, such as on-site information gathering, target classification, photogrammetric survey, or audio broadcasting. They may be better equipped to help with emergency management or disaster relief. In the case of low Reynolds number flights, the airfoil plays a crucial role in generating lift. This article presents an approach using open source/free software and commercial software ANSYS to evaluate and choose the airfoil for low Reynolds number flight designs and suggests a set of criteria used to evaluate the airfoils. Based on the maximum lift-to-drag ratio, we selected three different airfoils for further studies. The numerical simulations of the flow around the obtained/selected 2D airfoils (Eppler-326, Eppler-333, and Marske7) were carried out by using the computational fluid dynamics (CFD) software, Analysis system (ANSYS), at Reynolds number 2 x 10(5). From the results, the recorded maximum coefficient of lift for Eppler-326, Eppler-333, and Marske7 airfoils are 1.1584, 1.3468, and 1.0391 at stall angle of attack (12). Applications were demonstrated through the successful selection of a suitable airfoil (Eppler-333) for the design and development of a flying wing that achieved a maximum coefficient of lift of 1.34. For the design and development of flying wing applications, the Eppler-333 airfoil is highly recommended

The study also shows up that most of the users prefer to consent library to read newspaper and for preparing their competitive examination.

Electronic resources have become an important part of a library collection. The value and use of these resources have increased significantly, especially in the prevailing COVID-19pandemic period. The article discusses a study conducted to explore the status of e-resources in select university libraries of Haryana.This study is based on primary data collected using a self-designed questionnaire from three well-established, multi-disciplinary state universities of Haryana, namely Kurukshetra University (KUK), Maharshi Dayanand University (MDU), and Chaudhary Devi Lal University (CDLU).The study did find Vivekananda Library of MDU to be equipped with maximum hardware infrastructural facilities as compared to other two university libraries. All the three university libraries are automated and using LIBSYS software. E-ShodhSindhu is subscribed by all the university libraries. Libraries of KUK and MDU provide links of open access databases such as Directory of Open Access Repositories (DOAR), Directory of Open Access Books (DOAB), Directory of Open Access Journals (DOAJ) and National Digital Library of India (NDLI). MDU library and CDLU library are subscribing maximum e-book databases. E-journals are subscribed on perpetual access basis with archives by libraries of MDU and CDLU. The study further found that all university libraries take the feedback from their users regarding continuation or discontinuation of e-resources. Results of the study also reveal that only MDU library has permanent full-time librarian whereas other two university libraries are looked after by professor-in-charge of their universities, given the additional charge of librarian. The universities’ libraries of Haryana need to subscribe more e-resources and appoint full-time librarian so as to better serve their users in the post COVID-19, new normal situation.

Now days consumers are more conscious for their health and maintaining a better quality of life. They prefer to consume the products which are healthy for them, their family and will help them to attain maximum satisfaction. Money is not a limiting factor as far as food, cosmetic and medicinal products preserving health are concerned. The current scenario shows an inclination of consumer's interest towards the consumption of herbal and eco-friendly products which do not have side effects. This particular tendency has been responsible for extraordinary popularization of Patanjali products and generated curiosity to find out the attributes responsible for such revolutionary trends of Patanjali products. So the need was felt to study the consumer perception towards Patanjali products. The perception of consumer regarding attributes of Patanjali products were found satisfactory . V arious product attributes met with consumer expectations. All the consumers of medicinal products have safe investment attitude. Food product users have positive attitude and cosmetic product users have carefree attitude towards these products. Medicinal products were consumed basically with the attitude to acquire good health, food products to gain complete satisfaction with consumption and cosmetic products consume in order to use something new.

Consumer buying behaviour is the sum total of a consumer's attitudes, preferences, intentions, and decisions regarding the consumer's behaviour in the marketplace when purchasing a product or service. Presently consumers are more conscious for their health and maintaining the quality of life. They prefer to consume the products which help them to protect the good state of their health as well as provide maximum satisfaction. This particular tendency has been responsible for extraordinary popularization of Patanjali products. Patanjali products are pure and effective that satisfies the needs of consumers without affecting environment and health of consumers. In this study an attempt has been made to know the consumer buying behaviour towards Patanjali products. For this a survey was conducted on 90 randomly selected consumers who consume the Patanjali products since its starting in Pantnagar market (February, 2008). This paper studies the decision making process and the factors affecting the consumer decision process for Patanjali products. The findings of the study revealed that half of the respondents among the total sample reported to purchase Patanjali products due to their medicinal value. Half of the respondents reported that neighbours/relatives/family members were the major source of information about Patanjali products. Patanjali products have been evaluated as better quality and medicinal value of products by 40 per cent and 33.33 per cent respondents respectively. Advice and preference of family members and past experience with products are the major factors affecting decision making process whereas price, brand, advertisement, festive occasion and purchasing pattern as affecting factors were only reported by few of respondents.

Mycorrhiza is a symbiotic or mutualistic association between the fungus and the roots of the plants (Brundrett, 2004). The first drawings of mycorrhiza were provided by Nageli (1842). The word mycorhiza was first time used by Frank (1885) for the symbiotic association of certain fungi with the roots of plants. The Greek word „Mycorrhizen‟ means „fungus root‟. Kelley (1931, 1950) incorporated second „r‟ in the word “mycorrhiza” and carried out a thorough discussion of the derivation of this word. Frank (1887) recognized distinction between ectotrophic and endotrophic mycorrhiza which included ericaceous and orchid mycorrhiza.

Literature review enables us to gain a comprehensive overview and summary of the available information on a particular topic.

In this article, we have discussed about different approaches of reading habits of students and research scholars of different schools, colleges, universities and institutions. The literature on reading habit has always been a popular topic for research within various disciplines, but for the purpose of this article, this review has been limited to the field of library and information science, which is where many of the key articles are to be found.

Urinary stone disorder has afflicted humankind since antiquity and can persist, with serious medical consequences, throughout a patient's lifetime.The common component of urinary stone is calcium oxalate (CaOx).In spite of tremendous advances in the field of medicine, there is no truly satisfactory drug for the treatment of renal calculi.In the indigenous system of medicine, the leaves of Annona reticulata (Family -Anonaceae) are reported to be useful in the treatment of urinary stones.Hence, in the present study, the Annona reticulata have been selected for their anti urolithiatic activity on experimentally induced urolithiatic rats.

The color of the skin plays very important role in the society especially in India.Switra is a hypopigmentary disorder of skin.Based on the symptoms, Switra can be correlated to Vitiligo of modern science.This Vitiligo affects the estimated 1% of world's population.In the present study 22 cases of Switra were sampled in to 2 groups with 11 patients in each group.The first group of patients received Sramsana therapy followed by internal medicine and lepa.Patients of second group received only lepa.In first group moderate improvement was seen in 72.73 % patients and mild improvement seen in 22.27 % patients.In test group marked improvement was seen in 18.18 % patients whereas marked improvement was observed in 63.64 % patients and mild improvement in 18.18 % patients.When the results of the two groups were compared with unpaired't' test statistically non-significant was obtained which proves the application of lepa alone can produce repigmentation in the mandalas by decreasing their number and size.

Among Nasagath Rogas, most of the acharyas described pratishyaya with its complications which proves the seriousness of the disease.Acharya susrutha clearly mentioned in Uttar tantra that Pratishyaya is the disease condition in which Vata and Kapha dusti was observed.Allergic Rhinitis is a disease characterized by sudden and frequent attacks of sneezing, profuse watery nasal discharge associated with nasal obstruction which is intermittent, watering of the eyes, heaviness of head, respiratory distress and anosmia.The present study aims to comparatively evaluate the clinical efficacy of shadbindu gritha nasya with haridra khanda internally in pratishayaya.The principle objective of the study is to find a most effective, economical and simple treatment for pratishayaya.Here 45 patients of pratishyaya-Allergic Rhinitis were treated in 3 groups.15 patient of group A treated with Shadbindu gritha Nasya.15 patient of group B treated with Haridrakhanda orally.15 patient of group C treated with both Shadbindu gritha nasya and haridrakhanda as a combined therapy.After the enrollment of the patients in the study, vital signs and symptoms of Pratishyaya-Allergic rhinitis such as Nasa srava, Khavatu, Nasa avarodha, gala talu shuskata, were studied before and after the treatment.The results of the study indicated that the group c bestowed with highly significant relief in almost all the signs and symptoms in comparison to group A and group B.

Patanjali Ayurvedic Kendra is a type of medical store where all the medicines of Baba Ramdev are available any time and people can get easily these medicines in efficient price. It was started in February, 2008 in Pantnagar market. Patanjali Ayurvedic products are pure and effective, scientifically developed Herbomineral medicines prepared by Swami Ramdevji and Acharya Balkrishnaji. These products were broadly categorized into three main categories – Medicinal Value Products (Ayurved and Herbs); Food Products (Foods and Juices) and Cosmetic Products. The Kendra was started with 26 patanjali products but day by day the demand of consumers for Patanjali products has increased. To meet the consumer requirements number of products in every month has been added at retail store. Presently 120 products are available at the Kendra. An increase of 94 products of all three categories within just four years may be attributed to their high medicinal value, herbal nature based on Ayurveda and economic feature.
