The international opioid crisis highlights the important role of pharmacists in prevention, using their availability and drug knowledge to prevent abuse. In this study, the knowledge, attitudes, and practices of Mangalore pharmacists towards preventing opioid abuse were assessed. From February to March 2025, a cross-sectional survey was done among 203 pharmacists aged 18-46 years in Mangalore using a pre-tested structured questionnaire. Data were analyzed using the Chi-square test, and thematic analysis of qualitative feedback. Pharmacists showed high knowledge, with 93.6% identifying opioids' mechanism as binding to CNS receptors correctly, 78.8% identifying naloxone's role in reversing overdose, and 70.0% knowing prescription drug monitoring programs' usefulness. Attitudes were optimistic, with 92.6% considering patient education a primary responsibility, 92.1% identifying multiple visits to the pharmacy as misuse, and 93.1% supporting medication-assisted treatment. The practice was active, with 93.1% checking prescription drug monitoring programs for suspected misuse and 69.0% advising take-back programs, but 43.8% associated early refills with misuse. Mangalore pharmacists show strong knowledge, attitudes, and practice against opioid abuse, being very strong in education and medication-assisted treatment support but having voids in misuse detection (for example, recognition of early refill) and naloxone confidence. Stronger training, better prescription drug monitoring program access, and policy adjustments can enhance their role in India's opioid strategy. Pharmacists are presented as front-line champions of opioid misuse prevention in this study, with implications for localized harm reduction.

We present a series of large-eddy simulations to systematically investigate the impact of debris accumulation on the hydrodynamics and power production of a utility-scale marine hydrokinetic (MHK) turbine under various debris loads lodged on the upstream face of the turbine tower. The turbine blades are modeled using turbine resolving, actuator line, and actuator surface methods. Moreover, the influence of debris on the flow field is captured by directly resolving individual logs and employing a novel debris model. Analyzing the hydrodynamics effects of various debris accumulations, we show that an increase in the density of debris accumulation leads to more flow bypassing beneath the turbine blade. This, in turn, reduces the flow momentum that reaches the MHK blades at the lower depths, inducing significant fluctuation in power production. Further, it is shown that debris-induced turbulent fluctuations contribute to significant variability in the MHK turbine’s power production.

Lightweight materials are increasingly being used in engineering applications today. Composites are replacing traditional metallic materials in a variety of sectors, including aerospace, defence, and aircraft production, where there is a demand for structural materials with high strength-to-weight and stiffness-to-weight ratios. Natural fibre composites are also increasingly used in place of synthetic fibre composites in a variety of technical fields due to their affordability and environmental friendliness. In this particular study, Kevlar (Aramid fibres) is combined with other materials to improve the mechanical characteristics and impact resistance of composites. The only material that costs more than Kevlar is carbon fibres. The goal is to maximize mechanical qualities while utilizing the fewest amounts of pricey Kevlar fibres possible. The hand layup technique was used to create the hybrid composites, which included both natural and Aramid fibres. The performance of various mechanical properties was then assessed. In addition, a morphological examination was done to look at the interior structure of the composite materials that were examined. The results show that the hybrid composite, with or without the addition of nanoparticles, demonstrates great strength with little reliance on Kevlar fibres.

Shell and tube heat exchanger is the most common type of heat exchanger, widely used in oil refinery and other large chemical process. The energy present in the exit stream of many energy conversion devices such as I. C engines, Gas turbines etc. goes as waste, if not utilized properly. For example, the heat energy stored in the engine coolant can be utilized in a better way by recovering the heat for heating purposes inside the cabin. It is comparatively economical than the existing heating arrangements, which employ conventional heating coils. So, the present work has been carried out with a view to predicting the performance of a shell and tube heat exchanger in the field of waste heat recovery application. The objective of this project is to design a shell and tube heat exchanger and study the flow and temperature field inside the shell and tubes using ANSYS Fluent R14.5. An attempt has been made to calculate the performance of the above heat exchanger with and without baffles for parallel flow configurations, and the results so obtained have been compared.

Mobile pervasive environment interact with several devices at varying service ranges. The technical heterogeneity of pervasive environment is expected to increase the system flexibility and adaptability on modeling with context training phase. While working with context based training phase, time entity measure is considered as the significant issue. The evaluation of the services through numerous devices during training phase does not acquire an effective service monitoring on mobile pervasive environment. Mobile pervasive environment based information extraction fails to modify the patterns as activities change over time. To improve the flexibility of context training phase in mobile pervasive environment, an Active Context Source Discover Training Phase (ACSDTP) with Classifier Decision Tree Support (CDTS) mechanism is proposed in this paper. Our research work is to develop an effective modification (i.e., updation) of the pattern on training phase with real world context as per changes over time. Initially, the ACSDTP set up the available sensors in pervasive environment to work with the ever changing set of context users. The available sensors are maintained using the Active Discover process. Second, the CDTS mechanism is designed using weighted prediction for easy identification of context result on the training phase. Decision tree is operated separately using the learning techniques, where the identification is performed in a significant manner with minimal time factor. The learning process is performed to identify the inferred situations. Finally, the integration process is carried out to work with the complex association between the situations and sensor data in the mobile pervasive environment to achieve flexibility and adaptability factor. Experiment is conducted on factors such as time entity measure rate, precision ratio, and user context result determination level.

In some countries, a high percentage of the population relies on traditional plants for treating certain diseases. The aim of this study was to investigate the effect of G. alypum extract (GAE) and Alhagj marorum extract (AME) on lipid profiles in experimentally induced hypercholesteremic rats and on the blood pressure of experimentally induced hypertensive rats. Male Wistar rats weighing 200 - 300 g were divided into five groups: group 1 received a normal diet (negative control), group 2 received a high lipid diet containing coconut oil (10 g/kg/day), cholesterol (4 g/kg/day) and cholic acid (0.20 g/kg/day) (positive control), group 3 received a high lipid diet together with clofibrate (50 mg/kg/day), group 4 received a high lipid diet together with AME (200 mg/kg/day) and group 5 received GAE (200 mg/kg/day). The experiment continued for two weeks, then the rats were sacrificed and blood samples were collected for estimation of cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein. To induce hypertension, rats were divided into two groups (n = 8 in each group). Group 1 received normal saline (control) and Group 2 received dexamethasone (0.40 mg/kg, i.p.) for seven consecutive days. Later, the rats were anesthetized using thiopental and the carotid artery was cannulated for recording blood pressure. AME (40 mg/kg) or GAE (40 mg/kg) were injected through a cannula placed into the internal jugular vein at a dose volume of 0.1 ml. Systolic and diastolic blood pressure were measured before and after plant extract administration. The results showed that clofibrate GAE extract and ANE extract significantly decreased cholesterol, triglycerides, low-density lipoprotein and high-density lipoprotein as compared to high-lipid diet-treated rats. Data also indicated that administration of GAE or AME extract significantly decreased systolic and diastolic blood pressure in experimentally induced hypertensive rats. In conclusion, GAE and AME have antihyperlipidemic and antihypertensive activities and further investigation is needed to clarify the mechanism of these effects.

A mobile adhoc network is a Self-configuring network of mobile routers connected by wireless links. In the mobile adhoc network, each and every device moves independently in any direction so that there are frequent changes in the links. It is essential to learn the position of the neighbors because there is increase in location-aware services. So, there is a chance that the malicious nodes are easily abused the process. The significant problem in mobile networks is correctness of node locations and also it is primarily challenging in the presence of adversaries. So, the neighbor position verification protocol is used to a fully distributed, a lightweight NPV procedure which allows each node to obtain the locations advertised by its neighbors and asses their truthfulness. Further to extend neighbor position verification protocols in the proactive model that need to each node constantly verify the position of its neighbors. So, we introduce a technique called secure link state updating which provides secure proactive topology discovery that is multiply useful for the network operation. This technique is vigorous against individual attackers, it is capable to adjust its capacity between local and network-wide topology discovery, and also operating in networks of frequently changing topology and membership nodes. Experimental results show that the proposed system is high efficiency in terms of security when compared to the existing system.
