Evaluation of Water Infiltration Equations on Fadama Soils of Jos – North, Plateau State, Nigeria

The main purpose of this study is to obtain water infiltration parameters of the Fadama Soils on the Jos Plateau. Estimation of water infiltration on a soil is a major constraint due to its variability depending on local soil characteristics. This could be used in simulating infiltration for the Fadama soils when designing agricultural projects. Field measurement of infiltration were made using the double ring infiltrometer at the three locations (Rizek, Kerker and Shen – du) on the Jos Plateau. Readings were taken at intervals of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 65,70, 75, 80, 85, 90, 95, 100,105,  110, 115 and 120minutes. A set of field measured cumulative infiltration depths were used for the estimation of the model parameters for the five models, while the other set was used in simulating the infiltration equations. At Rizek, Horton and NCRS model performed better (0.997) followed by Philip’s model (0.973) while Kostiakov and modified Kostiakov’s model have the least value of 0.923 each. Philip’s model has the best fit (1.00) followed by the NCRS’s model (0.999) at Kerker while the Kostiakov and modifiedKostiakov’smodel had 0.997 each and Horton with the least value (0.986). At Shen – du, Kostiakov and modified Kostiakov performed better (0.997), then, Horton with (0.986), NCRS has 0.993 with Philip’s model having the least value (0.991).The study indicate that Kostiakov, Philip, Horton, NCRS and Modified Kostiakov’s models were capable of simulating infiltration for the Fadama soils (Rizek, Kerker and Shen – du) on the Jos, Plateau.

ABSTRACT Habib Zufar Ulhaq, NIT 51145381. T, 2019.” Analysis of the Effect of Fuel Quality and Fuel Pump Performance on the Performance of Injectors and Injector Performance Optimization Strategy in MV. KT 02”. Material Advisor Dr. A. Agus Tjahjono, MM., M.Mar.E Pembinbing Writing Capt. Dodik Widarbowo, M.T., M.Mar Semarang Shipping Science Polytechnic. The purpose of this study is to find solutions and problems for an incomplete combustion of diesel generator engine power that affects the power that will be produced by the motor caused by fuel quality and fuel pump performance on the performance of the injector. Injectors are important devices for diesel generators to support the performance of diesel generator engines. Fuel quality and fuel pump work on injector work have X1 fuel quality coefficient which is 0.249 so that it has a positive effect on injector work at 24.9%. The working coefficient of fuel pump X2, which is 0.607, has a negative effect on the work of the injector by 60.7%, thus the work of the fuel pump is very influential on the work of the injector. It was concluded that the quality of the fuel and the work of the fuel pump on the injector work were moderate. Based on the results of research conducted by the author on board and on the PIP Semarang campus it can be concluded that the quality of fuel and fuel pump work can affect the work of the injector so that the work of the diesel generator can work properly and the operation of the vessel can run smoothl

Improving Students Reading Comprehension on Hortatory Exposition Text Through Reciprocal Teaching Strategy

This study wasClassroom Action Research (CAR) to improve senior high school students readingcomprehension. In this project, Reciprocal Teaching Strategy (RTS) was used tohelp students find meaning in English reading texts. The process of RTScomprises of reading activities such as predicting, questioning, clarifying,and summarizing which typically involving interaction between students-studentsand students-teacher. Predicting helped the students hypothesized the generalidea of the text. Questioning helped the students get deeper understanding ofthe text by generating questions. The students clarified unfamiliar parts inorder to understand the clumsy part of the text. Summarizing monitored thestudents understanding by concluding the text. After three cycles of theteaching learning processes, the students reading comprehension improvedgradually

Predictors of mortality in brain abscess

Objective: Brain abscess carries significant morbidity and mortality. Our objective was to elucidate the clinical presentation of brain abscess and to assess predictors of mortality in these patients.Methods: All patients with a brain abscess presenting to the Aga Khan University Hospital, a tertiary care referral center in Karachi, Pakistan, were studied retrospectively. Statistical analysis involved univariate analysis and a logistic regression model.Results: Among the 66 patients analyzed, a distant metastatic focus of infection was the most commonly identified predisposing factor (29%). Otogenic infection was the commonest contiguous source and sinusitis was noticeably absent. Multiple abscesses were frequent (35%). Streptococci were the most common isolates (39%). Lumbar puncture was performed in 44% and steroids administered in 33%. Treatment was surgical in 58%. Most comatose patients were treated conservatively. Overall mortality was 29%. Univariate analysis identified comatose presentation and identification of a distant focus of infection as predictors of mortality. The logistic regression model, however, identified a distant focus of infection as the only independent predictor.Conclusion: Age greater than 30 years, corticosteroid use, multiple abscesses, performance of lumbar puncture and conservative management had no affect on outcome
