Wireless Sensor Networks(WSN)have revolutionized the processes involved in industrial communication.However,the most important challenge faced by WSN sensors is the presence of limited energy.Multiple research inves-tigations have been conducted so far on how to prolong the energy in WSN.This phenomenon is a result of inability of the network to have battery powered-sensor terminal.Energy-efficient routing on packetflow is a parallel phenomenon to delay nature,whereas the primary energy gets wasted as a result of WSN holes.Energy holes are present in the vicinity of sink and it is an important efficient-routing protocol for WSNs.In order to solve the issues discussed above,an energy-efficient routing protocol is proposed in this study named as Adaptive Route Decision Sink Relocation Protocol using Cluster Head Chain Cycling approach(ARDSR-CHC2H).The proposed method aims at improved communica-tion at sink-inviting routes.At this point,Cluster Head Node(CHN)is selected,since it consumes low energy and permits one node to communicate with others in two groups.The main purpose of the proposed model is to reduce energy con-sumption and define new interchange technology.A comparison of simulation results demonstrates that the proposed algorithm achieved low cluster creation time,better network error and high Packet Delivery Rate with less network failure. 展开更多

In recent years, traditional rice landraces have gained increasing attention among consumers, scientists, and nutritionists because of their nutritional and therapeutic value. The diverse rice gene pool of the Indian subcontinent is bestowed with indigenous rice types augmented with nutrients and phytochemicals. Landraces high in resistant starch and dietary fiber contribute to gut health and help prevent gastrointestinal disorders, whereas those with high-quality protein contents, such as glutelin and lysine, all-trans retinoic acid, as well as iron and zinc contents(even in polished rice), play a vital role in the alleviation of malnutrition and hidden hunger. Metabolomic studies have revealed the presence of novel bioactive molecules, including tocols(e.g., gamma-tocotrienol and alpha-tocopherol), phytosterols(e.g., campestrol, beta-sitosterol, and stigmasterol), phenolic acids(e.g., 2-methoxy-4-vinylphenol, 4-vinylphenol, 3,5-di-tert-butylphenol, 2,4-di-tert-butylphenol, ionol, and 2,6-di-tert-butylphenol), flavonoids [e.g., flavonolignans tricin 4′-O-(threo-β-guaiacylglyceryl) ether and tricin 4′-O-(erythro-β-guaiacylglyceryl) ether], anthocyanins(e.g., delphinidin and cyanidin), carotenoids(e.g., 7,7′,8,8′-tetrahydrolycopene and 1-hydroxylycopene), diterpenoids(e.g., sugiol), vitamin D3(a secosteroid), and bioactive vitamin D(e.g., calcitriol). These bioactive phytochemicals endow Indian rice landraces, rich in antioxidants, with antiphlogistic, antineoplastic, cardiac risk preventive, antiviral, and antitubercular activities, confirming their use in traditional Indian medicine. Furthermore, Indian landraces with a low glycemic index may benefit the Asian Indian phenotype, which is characterized by clinical anomalies such as insulin resistance, dyslipidemia(reduced high-density lipoprotein levels), and high dietary glycemic load. Therefore, the conservation of India's traditional rice varieties is vital for both sustainable agriculture and improving global health. 展开更多
