This paper presents an automated intravenous blood infusion unit to prevent a reflux using a load cell sensor. Intravenous infusion is frequently used in the hospital for patients' management and treatments such as dehydration and surgical operations. The sensor measures initial weight (500mls) of initial content of intravenous bag and set a threshold of 20mls or less, and then sends a signal through transmitter to receiver as an alarm indicating current state of the intravenous infusion. This is to support monitoring system by biomedical professionals and avoid blood reflux. The sensor has a strain gauge transducer that converts force into an electric signal in millivolts; two-18 pin microcontroller was deplored to modulate signals from the transmitter to the receiver, a buzzer indicator for sound notification, and LCD display monitor screen node station.

ABSTRACT:Diabetes is a disease of genetic and environmental origin. It affects the glucose-insulin endocrine metabolic regulatory system due to the malfunction of the insulin producing cells of the pancreas. The purpose of this study is to carry out a comparative analysis of the potencies of hunteria umbellata and metformin on Type 1 diabetes mellitus using bio-statistical analysis. The period of attaining normal blood glucose level across times was taken into consideration as a basis for comparing the efficacy of the oral antidiabetic herbal drug to that of the orthodox antidiabetic drug. The biometric analysis of data from five diabetic patients that were placed on herbal treatment were taken daily for a period of 3 weeks during which they attained normal fasting blood glucose level of between 70mg and 100mg as compared with a recovery period of 8 weeks for the 15 patients treated with metformin 500mg. These results showed that hunteria umbellata is more efficacious in the treatment of diabetes mellitus than metformin 500mg.

Hydroelectric power is a renewable source of energy. By principle, hydroelectric power generation relies on the law of conservation of energy where kinetic energy that resulted from the movement of the mass of water from the river is translated into electricity, the quantum of which depends on systemic variables viz: plant efficiency, volumetric water flow through the turbine and the head of the water from the water surface to the turbine. Understanding the dynamics of these variables, and the correlation between them are core to proper planning and management of a hydroelectric power station. In this Study, simple mathematical methods that include linear programming and statistical analysis based on simulation techniques were used to evaluate vital parameters based on the data obtained from the Hydrologic units of the Shiroro Power Stations in Nigeria. The overall aim of the study is to idealize power generation at Shiroro dam in and out of raining season so as to ensure optimum generation of electricity all year round in order to achieve energy sufficiency in Nigeria. The result of the study is encouraging as it supports the viability of the pumped storage system for generating hydroelectric power all year round. The coupling of the hydroelectric power with pumped storage system if properly harnessed could be the needed panacea for the erratic power supply in Nigeria.
