The objective of this report is to study the energy consumption of the Michael Okpara University of Agriculture, Umudike with a view to identifying energy conservation measures within the campus. Between January 2017 and November 2017, the electrical consumption totaled 782650 kWh at a cost of N45, 851, 543.49. This is equivalent to 2670512655.8 BTU of energy. For the same period, the total fuel and engine oil for the entire campus totaled N6, 629, 336.31. Energy savings up to 807.218kWh on a daily basis was identified in this report. It is recommended that machines and appliances should not be kept in standby mode. These devices should be switched off from the socket outlet when not in use. There should be penalties enacted for unnecessary power consumption by negligence of the user or system administrator for not switching off appliances while leaving the office. Other recommendations were made in the following categories: 1. Capital improvements. 2. Operations and maintenance. 3. Energy conservation measures.

This study deals with investigation of breadfruit shell (BFS) as potential energy source and efficacy of resin extracted from African pear (Dacryodes Edulis) as binder for briquettes. Different concentrations of the resin were mixed with constant weight of BFS to study the effect of the resin on the performance of BFS briquette. The density, moisture content, ash content, volatile matters and fixed carbon of the BFS briquette were obtained as 0.672g/cm3, 10.24%, 7.23%, 68.76% and 23.92% respectively. This study showed that the resin has effect on the performance of the briquette. Thus, the ignition time, calorific value and fuel efficiency increased with increase in resin content, while increase in resin content decreased the mass of briquette consumed, burning rate and specific fuel consumption. The optimum performance was recorded at resin content of 0.16g/g biomass, with calorific value and fuel efficiency obtained as 20036.4kJ/kg and 51.12% respectively. Therefore, breadfruit shell is a potential energy sources, and can be useful substitute for refined petroleum products for heating..

This paper explores the hazards of the roads and the confusing factors of the drivers.The road-selected area is from Vikarabad to Kerelli Towns. The road length is of 10 Kilometers. Theroad connects Vikarabad – Tandurtowns of Telangana State. It is a busy road connecting the industrial, commercial areas, has a mixed traffic and Hilly terrain, which leading to accidents. The Audit had conducted following the guidelines of, IRC: 67-2012, IRC: 35-1997, IRC: SP: 88. Correction of Road signs, markings, message signs, hazard markers, traffic safety barriers, identification of Blackspots, delineators had done based on the requirements. This paper worked for Safe roads, Forgiving roads. In conclusion, we argue that significant measures need to take on Road Safety aspects to mitigate the accidents and ensure the safety to vehicular traffic..

The present investigation has brought out the ground truth, how religious festivals, customs and rituals play a far reaching role to lead the pollution of water. The strength of water pollution of the river Ganga and other streams fluctuates seasonally. Due to further supply of water through heavy rainfall, the DO, BOD, COD, Hardness, Alkalinity, Total Nitrogen in water, Heavy Metals, Detergents, Velocity, Temperature and pHlevel slightly fluctuates during the monsoon. It becomes alarming during the festivals as huge number of pilgrims and tourists gather from different parts of the country and world. Present study concluded that there were minor differences in physico-chemical parameters of all the three sampling stations selected for their study. Research show that all the parameters which have been studied are still under the standard limits but some of them are very closer to them is an alarm for increasing pollution status. Due to regular dumping of ashes and bones of dead body, effluents of industries, hotels and sewage water of city should be treated before mixing in the river Ganga. Besides, this much consideration should be paid to control the pollution maintain the limits. The study not only comprises all types of threats of the area but also comprises the suggestions and recommendations concerning the management of natural hazards and combating the illegal human interference on entire environment..

Mathcad is a sophisticated computation and presentation tool, which is versatile, easy to use, and accessible. It holds strong potential as a learning aid for education and training. This paper demonstrates the use of Mathcad to supplement and enhance traditional teaching and learning methods both inside and outside the classroom. The paper focuses on the topic of reinforced concrete biaxial column design. Interactive teaching and learning devices in reinforced concrete biaxial column deign produced using the presentation and programming features available in Mathcad. This paper also compares the results of the Mathcad for the biaxial column with the computer software "SP Column" and the results obtained from the Mathcad program are quite close to the ones obtained from the computer software.

The present study had as objective to study and evaluate the evolution of the microstructure and the mechanical properties of the SAE 1045 commercial steel, subjected to a tempering heat treatment at 850 ° C, using 3 different cooling media: air, water and mineral oil, with subsequent treatment of tempering at 300 ° C. Using hardness and optical microscopy as tools of analysis and data collection, it was possible to determine the evolution of the microstructure and the mechanical properties of the samples before and after the treatments, as well as to perform a systematic and comparative analysis between them. By means of the results obtained it can be concluded that the SAE 1045 steel does not present any alteration of its properties and microstructure when subjected to tempering using air as a cooling medium. However, in relation to the tempering using water and oil as cooling media, a severe microstructural alteration was observed, evolving completely to a microstructure formed by martensitic grains. A significant increase in the hardness of the material was also observed reaching a plateau of 400% hardness from the starting material soon after quenching and 340% after tempering..

In this paper, the author establishes four interesting theorems exhibiting interconnections between images and originals of related functions in the Laplace transform. Further, we obtain five new and general integrals by the application of the theorems. Two known results are also given as a direct consequence of the third theorem. The importance of our findings lies in the fact that they involve the  -function which are very general in nature and are capable of yielding a large number of simpler and useful integrals merely by specializing the parameters in them.
