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.

Health technology innovation in low- and middle-income countries (LMICs), including countries in Africa, falls far short of meeting the healthcare needs of these settings. The result is a heavy reliance on products and technologies imported from industrialised countries that are often not suited to, or sustainable for, LMICs. Appropriate healthcare products for LMICs are best developed in these countries, where local knowledge and understanding of needs, context and available resources may be incorporated into designs and implementation plans. The objectives for enabling health technology development in LMICs include: 1) expanding the base of expertise through research training programmes with a problem-solving focus; 2) stimulating new knowledge, approaches and solutions by enabling innovation; and 3) integrating research communities within and across institutions to build critical mass. The field of biomedical engineering is central to health technology innovation. This book is a response to the need for biomedical engineering capacity in Africa. It is grounded in the African context. It serves as a resource for academics and students in biomedical engineering, for those interested in entering the field in any capacity and for practitioners at every stage of product development. University leaders intent on establishing new biomedical engineering programmes or departments, may draw on the content for guidance on structuring their offerings. The book reaches beyond Africa, as it is relevant to other LMIC settings, and provides insights to guide global health initiatives focused on technology innovation.

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.

The paper depicts design and prototypic implementation of household automation switching system for electrical appliances using web based interface technology. The proposed system consists of two parts, the first part is the hardware module, which provides appropriate interface to switches of home appliances. Second part is the software component that comprises the user control interface which monitors and controls energy consuming units in the household. Users and system administrator can locally (LAN) or remotely (WAN) control system code to activate or deactivate a desired appliance. The outcome of the study revealed that the smart household switch engendered substantial reduction in energy consumption on all kinds of appliance and it poses no threat to security of lives and properties. The device is desirable for conservation and efficient use of energy.
