This research measured and compared the emission results of high mileage cars and sport utility vehicles. It further investigated the emission contents of car and SUVs exhaust of low mileage and high mileage at idle condition of the engine, paying more regards to harmful pollutants. The analysis showed that significant amounts of CO, NOx, HC, were emitted in cars and SUVs with high mileage and high engine capacity compared to ones with low mileage and lower engine capacity. The six vehicles studied were; four high mileage and two low mileage vehicles (111,000km-113,000km and 14,000km–16,000km respectively) which is the range of passenger cars predominantly used in Nigeria.........

A Smart and economically viable solar power charge controller has been design and implemented. The system was implemented using Arduino Microcontroller. The microcontroller was used in order to make the system smart, robust and simple. The system was tested under different atmospheric conditions. The result obtained shows that the developed charge controller performs efficiently. The system is also shown to be economically viable as the major component in its development is the Arduino microcontroller..

Thecompetition between two energy sources for the same market which results in the replacement of one source by the other, based on dynamic model derived from biomathematics, previously applied in 2004, by authors in the Brazilian LPG x Pipelined NG (PNG)dwellingconsumption market is analyzed. The proposed model seems to be useful to increase the knowledge of the relationship between input and output variables in a system and the results can improve the communication rapport between theoretical modelers and decision makers.The forecasting results are compared with the actual data.......................

Fluid mechanics always plays a predominant role in different kinds of engineering streams. The study of fluid flows is always an area of interest and it consists of different applications like flow past cylinders, flat plate, and flow over suddenly expanded geometries. This paper deals with the experimental study of fluid flow over suddenly expanded geometries at different Reynolds numbers. It is difficult to identify the flow phenomena when the flow is inside a pipe. Hence the fluid is made to flow in an open channel so that the flow phenomena can be easily observed. A suddenly expanded geometry is introduced during this flow at a certain distance and a flow phenomenon is observed....................

The granulometry of fine aggregates is a fundamental test for the production of quality concrete [1], for this reason the American Association of Materials Testing (ASTM) has created a standard where it shows a granulometric ideal curve (formed by an upper bound and a lower limit), mentioning that the fine aggregate used for the preparation of concrete must be within these limits [4].At present, there are many mathematical models that predict fine aggregate granulometry, but none of them conforms to ASTM specifications [5]....................
