This study covers the evaluation of the synergistic effect of Datura stramonium leaves extract-Zn2+ in the corrosion inhibition of mild steel in well water. Varying effects of different concentrations of the extract and 5ppm of Zn2+ on the corrosion inhibition of the mild steel specimen will be determined in order to ascertain the synergistic effect that exists between the leaf extract and Zn2+
ABSTRACT For the past few years, the oil and gas industry has faced several economic, geographic and technical challenges largely due to decline in crude oil prices and market volatility. In the quest to address some of these challenges to accelerate production and subsequently maximize ultimate recovery, operators are limited to remote hydraulic and electro-hydraulic monitoring and control of safety valves providing the means of obtaining downhole production data which demands peri...
The availability and stability of electrical energy is necessary for domestic and industrial use. But unfortunately the monopoly which the Power holding company of Nigeria (PHCN) enjoys in this country is not in favor of the electricity users, because the supply is never constant and damages occur due to inconsistency of this supply is very enormous. However, millions of naira’s are lost every day in the commercial and industrial sectors, and even at the same time a lot of Lives are wasted ...
ABSTRACT The primary objective of this study is to identify the most appropriate herbal plants for the removal of contaminants from water and also to develop a water treatment kit at an affordable cost for the society. Moringa Oleifera was chosen for this study, the effectiveness of these herbs in the removal of fluoride from water shows that Moringa Oleifera is economically viable, physically feasible and socially acceptable. Moringa Oleifera seed is an organic material that has proven eff...
Cassava is produced in a large quantity in Nigeria. One of the products emerging from its processing has turned out to be a major staple food in the nation, which is ‘garri’. Due to insufficient and inadequate processing equipment; cassava has been susceptible to wastage and ‘garri’ production has been reduced in scale, thereby resulting in insufficiency and high cost of ’garri’ in the market. In order to ease the production process, a compact mechanized cassava mash/‘...
Malaria is a global public health problem, caused by malaria parasites transmitted by the vector adult female Anopheles mosquitoes. The life cycle of Anopheles mosquito (Order: Diptera) has six stages egg, four larvae instars and pupa. The immature stages are aquatic and determine the abundance, distribution and fitness of the adult Anopheles mosquito. The physicochemical parameters (Conductivity, Salinity and Total Dissolved solids) of water affects survival and development of the larvae. Th...
The aim of the project is to design a renewable energy system that can meet the current and projected electricity demands for the island of Great Cumbrae. This should be achieved by providing a stable electricity output and the meet the calculated total annual base load supply of 11.29 GWh. In addition to providing a stable supply of electricity, the environment and social impacts that arise from the project relating to Great Cumbrae should be minimised as well as coinciding with a techn...
This research is a quantitative study using 4th grade reassessment on one on one technology and its effect on student achievement and motivation.
Sustainable energy sources have been a topic of interest over a period of time for many researchers. Nuclear energy is one of the sources that have long been exploited for generating heat and electricity both in large scale and small scale. One of the methods for converting this heat into electrical power is using thermoelectric generators. Radioisotope thermoelectric generators are currently the longest-lived sources of energy; it does not require any human maintenance or refuelling. This pa...
This is a research work carried out on battery cage system of poultry management. It's all about how to minimize waste from poultry birds and also how to convey waste by employing the help of a belt conveyor
The electricity produced by renewable energy sources (RES) is constantly increasing worldwide thanks to government policies and technological advancements. Photo voltaic cells are actually a fast rising technology as the source of its power is a commodity that is abundant in this part of the hemisphere. Uncertainty also dominates in the area of the conditions at which the photovoltaic cells are operating, their optimal weather conditions and the effect of the conditions on their outpu...
ABSTRACT ABSTRACT It is not doubtful that effective and efficient waste management is essential for the development of a smart city. In developing and most developed countries of the world, overflowing waste from waste bins located at strategic positions in streets or close to residential areas both destroys the aesthetics of the environment and constitutes air pollution to the environs when the...
Both biometric behavior study and fruit biochemical analysis of five varieties of Syrian Pistacia vera introduced in Algeria in 1998 and raised in semi-arid bioclimatic stage (common Maoussa, Mascara, Algeria) led to a qualitative comparison. Based on the pistachio descriptor criteria established by the International Plant Genetic Resources Institute in 1997, characterization and descriptor of female varieties of pistachio were performed. The obtained results allow the better choice of sp...
The present work is to study the emergence and growth of seedlings of five pistachio varieties that are: Batouri, Achouri, Neb-Djemel, Adjmi and Bayadhi. The study was conducted in a greenhouse temperature and photoperiod were controlled. The seeds are germinated in pots filled with peat without going through the damp cold stratification at a temperature of 4ºC. The results obtained showed that growth parameters (length and diameter of the plants) revealed significant tests while other p...
Salinity is a major problem directly affecting the ecological balance and the development of agriculture in the Mediterranean basin, particularly North Africa. This phenomenon is considered as the most important abiotic factor limiting crops growth and productivity, degrading and polluting soils in arid and semi-arid. In order to study the influence of salinity, on the physiological parameters and to assess the potential of adaptation of the olive tree in a saline environment, three parcels c...
