ANTIHYPERGLYCEMIC AND ANTINOCICEPTIVE ACTIVITY EVALUATION OF ‘KHOYER’ PREPARED FROM BOILING THE WOOD OF ACACIA CATECHU IN WATER

‘Khoyer’ is prepared by boiling the wood of Acacia catechu in water and then evaporating the resultant brew. The resultant hard material is powdered and chewed with betel leaves and lime with or without tobacco by a large number of the people of Bangladesh as an addictive psycho-stimulating and euphoria-inducing formulation. There are folk medicinal claims that khoyer helps in the relief of pain and is also useful to diabetic patients to maintain normal sugar levels. Thus far no scientific studies have evaluated the antihyperglycemic and antinociceptive effects of khoyer. The present study was carried out to evaluate the possible glucose tolerance efficacy of methanolic extracts of khoyer using glucose-induced hyperglycemic mice, and antinociceptive effects with acetic acid-induced gastric pain models in mice. In antihyperglycemic activity tests, the extract at different doses was administered one hour prior to glucose administration and blood glucose level was measured after two hours of glucose administration (p.o.) using glucose oxidase method. The statistical data indicated the significant oral hypoglycemic activity on glucose-loaded mice at all doses of the extracts tested. Maximum anti-hyperglycemic activity was shown at 400 mg extract per kg body weight, which was slightly less than that of a standard drug, glibenclamide (10 mg/kg body weight). In antinociceptive activity tests, the extract also demonstrated a dose-dependent significant reduction in the number of writhings induced in mice through intraperitoneal administration of acetic acid. Maximum antinociceptive activity was observed at a dose of 400 mg extract per kg body weight, which was greater than that of a standard antinociceptive drug, aspirin, when administered at a dose of 400 mg per kg body weight. The results validate the folk medicinal use of the plant for reduction of blood sugar in diabetic patients as well as the folk medicinal use for alleviation of pain

Design and implementation of voice Command-Based robotic system

This project is designed to control a robotic vehicle by voice commands and manual control for remote operation. For detecting the signals provided through any mobile application, an ATMEGA32 microcontroller is employed in conjunction with a Bluetooth connection that is linked to a control module. The Bluetooth receiver connected to the Arduino receives serial data delivered from mobile application. We will deliberate how to control robot-controlled car using Wi-Fi module through android application of an android mobile. It provides control commands over Bluetooth that include managing the motor’s pace, detecting, and exchanging data with mobile regarding the robot’s direction as well as range from the closest barrier

Performance analysis of a FSO link considering different atmospheric turbulence

Free space optical (FSO) technology is a quick-to-deploy and economical way of getting access to the fiber optic network. FSO technology not only offers fiber-quality connections, but it also offers the sector’s cheapest transmission capacity. FSO systems complement legacy network commitments and function in harmony with any protocol, saving significant up-front investments as a completely protocol-independent broadband gateway. An FSO link may be purchased and deployed at a fraction of the cost of installing fiber cable and for roughly half the cost of equivalent microwave/RF wireless systems. With exception of RF wireless technologies, FSO does not need the purchase of expensive spectrum licenses or the fulfillment of additional regulatory criteria. The purpose of this study is to examine the performance of FSO-based optical access networks. Analysis of the performance in detail, with a focus on BER is also described

Study on Advanced Image Processing Techniques for Remote Sensor Data Analysis

Image processing is the act of altering photographs with arithmetic computations for a variety of objectives including erasing clean lines, dividing groups of objects, noise removal from photos, detecting edges, and so on. Remote sensing is a method for observing the planet's surface or environment through satellites or from the air (via airplanes). Electromagnetic radiation reflected or radiated by the earth's surface is recorded using this approach. Numerous techniques and technologies can be used in remote sensing to monitor electromagnetic waves of different wave lengths, including visual, infrared, heat infrared, and so forth. In this study, digital cameras are utilized to acquire photos in the visible range and then used advanced image processing and filtering algorithms to the raw data. Homomorphic filtering, median filtering, Gaussian filtering, histogram-based thresholding, contrast stretching, and other techniques are used. The results of this research will be valuable for enhanced picture analysis
