Comparative Study of Lube Oils Syhthesized from Chemically Modified Castor and Soybean Oils Using Additive

Petroleum-base-lube oils are non-biodegradable and their continuous use results in environmental pollution. Comparatively, vegetable oils are biodegradable, less toxic and renewable hence, their use as base stock for lubricant production will not only serve as viable alternatives but also help in avoiding environmental deterioration. This paper compares the properties of soybean and castor oils as potential sources for synthesizing bio-lubes when mixed separately with styrene as additive. Styrene was used because of its advantageous polymeric behavior. Samples of soybean and castor oils were mixed with different volumes of the additive at 50 C. Fluid properties were determined with emphasis on viscosities of the oils. For the castor oil samples, their viscosities compare with those of standard oils at 40 C and at 100 C. These values show that soybean samples can replace base oils used in SAE15W SAE20 monograde lubricant while castor oil samples can replace the SAE50 SAE60 lubricants.

Atmospheric configurations of aerosols loading and retention over Bolgatanga-Ghana

Bolgatanga is located on latitude of 10.78 oN and longitude 0.85 oW. This research is aimed to estimate the aerosols loading and retention over Bolgatanga-Ghana through a conceptual model that is made up of analytical, statistical and Matlab curve-fitting tool. The model’s accuracy was established over the aerosol optical depth for a thirteen-year satellite data set from the Multi-angle imaging specto-reflectometer (MISR). The maximum aerosol retention was 31.73%. Its atmospheric constants, tunning constants and the phase difference over Bolgatanga was found to 0.67, 0.24 and  / 4 respectively. The phase difference expresses the different kinds of network topologies and beam forming methods for measuring devices that may be used in Bolgatanga. Therefore a good estimation of the aerosols loading and retention over Bolgatanga, we may be in the best position to controlling its effect on health, farming, rainfall pattern, cloud formation and regional climate.

Theoretical Study of Aerosols Loading and Retention Over Bolgatanga, Ghana

The aerosols loading and retention over West Africa have grave effect on life-forms through the impact on health, farming, rainfall pattern, cloud formation, and regional climate. Bolgatanga can be found on the latitude and longitude of 10.78°N and 0.85°W, respectively. This research is focused on an investigative consideration of the negative effect of atmospheric aerosols over Bolgatanga in Ghana through a conceptual model using analytical and descriptive statistical methods with MATLAB curve-fitting tool. The model was verified using aerosol optical depth data set from satellite imagery—multi-angle imaging specto-reflectometer (MISR)—obtained over a period of 13 years. The highest percentage increase of aerosol retention was 64.27% over the research site. The model was used to estimate the atmospheric constants as 0.67, tuning constants as 0.24, and phase difference as ± π 4 .

Theoretical design of lightning panel

The light trapping device (LTD) was theoretically designed to suggests the best way of harvesting the energy derived from natural lightning. The Maxwell’s equation was expanded using a virtual experimentation via a MATLAB environment. Several parameters like lightning flash and temperature distribution were consider to investigate the ability of the theoretical lightning panel to convert electricity efficiently. The results of the lighting strike angle on the surface of the LTD shows the maximum power expected per time. The results of the microscopic thermal distribution shows that if the LTD casing controls the transmission of the heat energy, then the thermal energy storage (TES) can be introduced to the lightning farm.
