Abstract Humans have been harnessing solar energy for thousands of years—to grow crops, stay warm, and dry foods. According to the National Renewable Energy Laboratory, “more energy from the sun falls on the earth in one hour than is used by everyone in the world in one year.” Today, we use the sun’s rays in many ways—to heat homes and businesses, to warm water, or power devices. Solar, or photovoltaic (PV), cells are made from silicon or other materials that transform sunlight dir...

There exists rights, powers and restrictions on the holders of the petroleum licences in the Nigerian Petroleum Industry, but these rights and powers are whittled down by the provisions of the Petroleum Act and other relevant legislations. The constitution vests the ownership of mineral resources to the Federal Government and by the Land Use Act, all lands are vested in the State Government. The rights and powers of the holders of the licences/leases can be revoked but must be done in accorda...
Abstract Ferroelectric RAM or FRAM or FeRAM is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory. It combines the fast read and write access of dynamic RAM(DRAM) - the most common kind of personal computer memory - with the ability to retain data when power is turned off (as do other non-volatile memory devices such as ROM and flash memory). Because FRAM is not as dense (cannot store asmuch data in the same ...
Abstract- Palm kernel production potentials of several countries are far from been fully exploited. At present, many countries are operating below expected capacity. The motive of the project work is based on fabrication and modification of a palm kernel cracker and separator, so as to help farmers improve the efficiency of output based on time, reduce stress and injuries they incur in the process of cracking palm kernel and separating the kernel seed from the shells manually. The major pri...
Dewatering means “the separation of water from the soil,” or perhaps “taking the water out of a particular construction problem completely.” Areas that once were deemed unsuitable for construction due to a high water table are now being developed to meet the needs of an increasing population. With the decline in land availability to build or expand highway networks above ground, underground facilities, such as mass-transit lines, may represent the future of transportation. Underg...
ABSTRACTCurrently owing to the annual increase of data, there is urgent need for anthropometric database and useful approaches, in designing machine, equipment, facilities, workspace and other products. Fuzzy clustering which is an important way of clustering is an approach where an object is grouped into more than one partitions. The approach is used to bridge the gap between the anthropometry dimension of an individual and garment size which is a problem attributed to the size of the garmen...
ABSTRACT Moringa oleifera grows in the tropical and subtropical regions of the world. It is commonly known as ‘drumstick tree’ or ‘horseradish tree’ in Nigeria. Moringa can withstand both severe drought and mild frost conditions and hence widely cultivated across the world. With its high therapeutic values, every part of the tree is suitable for either nutritional or commercial purposes. The leaves are rich in minerals, vitamins and other essential phytochemicals. Extracts from the le...
Some inventions are glamorous and very sophisticated – microchips embedded system technology –and more while some others are quieter, yet not less relevant in easing the work that man has to do with his own energy. Pumps do fall in the latter category (Mario, 2001). This project is intended to model a portable solar powered suction pump. Pumps are devices that transfer fluids (liquid or gas) from one point to another through some mechanical means. Pumps generally have being in use for cen...
A “disaster” can be defined as ‘a calamitous event, especially one occurring suddenly and causing great loss of life, damage or hardship, caused by negligence, bad judgment, or the like, or by natural forces, as a hurricane or flood….the emphasis is on grief or sorrow caused…or the destruction or irreparable loss. they often come with such inexplicable emotional force that triggers in man that innate human desperation or determination for survival against all adversities, n...

Abstract This research work focuses on development of practical instructional guide in the production of portable Universal SerialBus (UBS) Charger. Two research questions were set to guide the study. The study was carried out in Federal College of Education(Technical) Omoku Rivers State. The study adopted research and development design. The population for this study is 337 NCE I, II,and III electrical / electronics technology students. The sample of the study consists of 103 NCE I, II, and ...
This write-up gives an overview of lubrication, lubricants, their types and general properties, and the principles of lubricant application. It further emphasizes on the different methods of lubricant application, specification, selection and storage.
INTRODUCTION TO NANOTECHNOLOGY Nanotechnology has gained ground in the twenty-first century and is rapidly growing due to the ability to manipulate and harness properties of assemblies that are at the nanosize scale of biomolecules. Bionanotechnology is defined by science’s growing ability to work at the molecular level, atom by atom, combining biological materials and the rules of physics, chemistry and genetics to create tiny synthetic structures [1]. The end result of nanotechnology...
