Structural analysis, metamorphism, and geochemistry of the Archean granitoids-greenstones of the Sukumaland Greenstone Belt around Geita Hills, Northern Tanzania  [PDF]
Nelson Boniface, Abdul H. Mruma
Natural Science (NS) , 2012, DOI: 10.4236/ns.2012.48070
Abstract: Greenstone rocks, which include Banded Iron Formations (BIFs), tuffs, volcanic flows (basalt, andesite and rhyolite), and clastic sedimentary rocks (shale-mudstone, greywacke-sandstone and conglomerate), crop out around Geita Hills and are flanked by granites and granodiorites. BIFs and tuffs occupy larger area than other lithological units, which crop out as patches. Structural analysis indicates that layers of green-stone rocks are folded and display a regional fold axis with an attitude of 320o/40o. Low-grade metamorphic mineral assemblages (actinolite-epidote-chlorite in basalts and muscovite-epidote-chlorite in granitoids) are common in these rocks; this indicates a regional metamorphism at greenschist facies. However, BIFs and basalts are locally metamorphosed to epidote-amphibolite and amphibolite facies. Basalts belong to the tholeiite series whereas granites, diorites and rhyolites belong to the calcalkaline series. Chondrite normalized rare earth element pattern of basalt is flat and plot slightly below the average N-MORB values suggesting the enrichment of the light rare earth elements, which means that mantle magma source was an E-MORB. Granitoids and rhyolites have strong affinities to the continental arc source magma displaying strong enrichments in the LREEs with (La/Sm)N values ranging between 2.53 and 3.95 in rhyolites and between 4.08 and 5.40 in granitoids. The granitoids are classified as the I-type synorogenic metaluminous granites and granodiorites. Geochemical signatures suggest that the Geita Hills basalts erupted at the enriched mid ocean ridge setting of the back arc setting, and the granites, granodiorite and rhyolite formed in a volcanic arc setting particularly the continental arc.

H. B. Bhaskar, Abdul Sharief
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2012, DOI: 10.4236/jmmce.2012.117052
Abstract: The present study deals with investigation relating to the influence of wear parameters like sliding speed, applied load and sliding distance on the dry sliding wear of aluminium metal matrix composites. The design of experiment approach was employed to acquire data in controlled way using Taguchi method. A Pin-on-disc apparatus was used to conduct the dry sliding wear test. An orthogonal array, signal-to-noise ratio and analysis of variance were employed to investigate the wear behavior of aluminium and it’s composite. The mathematical model was obtained to determine the wear rate of the aluminium and it’s composite. The confirmation tests were conducted to verify the experimental results. The incorporation of Be3Al2(SiO3)6 as reinforcement material in aluminium matrix material improves the tribological characteristics.

International Journal of Social Science and Humanity , 2013, DOI: 10.7763/ijssh.2013.v3.198
Abstract: The measures that are being taken by the Countries to prevent the violation of human rights by the policedifferwidely in its effectiveness. The disparity among the nations accentuate for super national bodies on regional basis for the effective protection of human rights from the police. There exist European, Inter-American, African, Minsk and Arab regional systems for the protection of Human rights on super national basis. Regional systems also differ in protecting the human rights from the police mainly due to the socio-economic and cultural diversities that exist in the regions. This article analyses how effective is the regional mechanisms in protecting human rights from the police.
The Toxic Effects of Crude Oil in Some Freshwater Cyanobacteria  [PDF]
Abdul Hameed M. Jawad Al Obaidy, Muwafaq H. M. Lami
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.55039

Toxicity effect of the Iraqi crude oil on the growth of two Cyanobacteria strains Microcystis flos-aquae (Wittr.) Kircher (unicellular) and Nostoc carneum Agardh (filamentous) was studied basing on it is biomass expressed as chlorophyll-a (μg/ml). Growth rate and doubling time of the cells were also calculated accordingly in present or absent of the crude oil. Also, Microscopical examination was observed to detect the morphological changes. Both species appeared different responses towards oil toxic influences with different concentrations and time of exposure. Growth was decreased gradually with Microcystis with addition of 10, 30, 50 and 70 mg/l of the crude oil, slightly toxic effects were observed with Nostoc in comparison to the control. Different significant correlations (P ≤ 0.05) were observed between growth of the cyanobacteria and the oil concentrations. Furthermore, results demonstrated that Microcystis was considered to be more sensitive than Nostoc towards crude oil concentrations.

Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.55039

Objective: To document our experience on the use of Jadelle/Implanon contraceptives that was recently introduced into Ahmadu Bello University Teaching Hospital (ABUTH), Zaria, Nigeria. It is pertinent to generate data on the experiences in the use of this contraceptive in a cross sectional study within Zaria, Northern Nigeria. Method: Data on consecutive clients that accepted Jadelle/ Implanon from June 2009 to November 2013 at ABUTH were extracted from their cards and analyzed using SPSS version 17. Out of a total of 11,502 clients that were for contraception during the period under review, 798 accepted Jadelle/Implanon accounting for 7% of the total clients. All the clients were married. About 67.8% were Muslims while 27.2% were Christians and 5% belong to other sect. 4140 (36%) had tertiary education. Most of the client has been on one form of modern contraception; only 16% were first time users who accepted implant after counselling. 37% of the?clients are full time housewives. The discontinuation rate was found to be 26% for Jadelle and 19%?for Implanon. No pregnancy was recorded during this period. Conclusion: Jadelle/Implanon account for 7% of contractive uptake and a high discontinuation rate was found among the users.

Abdul H. Zaid, Sunil Sapru, Jennifer Costello, Chirag Boradia
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.311008
Abstract: Introduction: Persistent hypoglycemia in the setting of acute renal insufficiency while on sulfonylureas is potentially a life-threatening complication. A case of severe hypoglycemia in a diabetic with acute on chronic renal insufficiency while on glimepiride is described here. Case Report: A seventy-six years old man presented to our emergency department with gradually progressive generalized weakness, dyspnea on exertion and lightheadedness. His medical history included congestive heart failure, hypertension and chronic kidney disease from non-insulin dependent diabetes. He reported good compliance with his medications which included glimepiride, 2 mg daily. Patient’s spouse reported a blood sugar reading of 22 mg/dL at home which prompted the emergency department visit. On presentation, the patient was tachycardic, tachypneic and diaphoretic. Initial glucose meter reading was found to be 36 mg/dL and a blood glucose level on the metabolic panel was 49 mg/dL. Patient serum creatinine was 2.5 mg/dL, increased from a baseline of 1.8 mg/dL. While in the emergency room, the patient received 50% dextrose intravenously eventually requiring an intravenous infusion of 10% dextrose. Despite this treatment, the patient remained persistently hypoglycemic with blood sugars less than 80 mg/dL. A decision was made at this point to administer 50 micrograms of octreotide subcutaneously. Two hours later, the patient’s blood sugar started to improve and the intravenous 10% dextrose was discontinued. Eight hours later, the patient received another dose of 50 micrograms of octreotide and remained consistently euglycemic. Upon discharge, he was asked to discontinue glimepiride. Conclusion: Severe refractory hypoglycemia is a serious complication of sulfonylurea therapy in diabetics with renal insufficiency. Prompt recognition and initiation of octreotide are effective in reversing hypoglycemia in these instances rapidly and safely.

Fuzzy Knowledge Base System for Fault Tracing of Marine Diesel Engine
H. M. Abdul-Kader
Communications of the IBIMA , 2009,
Abstract: Marine diesel engine provides the prime mover for the majority of ship propulsion systems and as such plays a fundamental role in ship operational and economy. Ship owners and operators focuses to the development of improved method of analysis, operation, fault condition diagnosis, performance monitoring, performance optimization, and recently emission analysis and control. Information technology can be used to raise the technological level of diesel engine automation and control to enable a new generation of engines with high level of safety and friendly use for the operators. Fuzzy knowledge base systems are practically suitable for these problems and will inevitably become an essential element in marine technology. The main objective of this paper is designing a prototype fuzzy knowledge base system (FKBS) to improve the capabilities of fault tracing for a ship diesel engine. Such system can be used by non-experts to improve their problem solving skills. Also it can be used as a training tool for new staff. For implementing the Knowledge base system, a special software package has been proposed. This software package has been designed for building the prototype knowledge base system shell. The developed system has a friendly user interface and does not require any special programming skills to encourage all operators to use it.
Extrapolating gravitational-wave data from numerical simulations
Michael Boyle,Abdul H. Mroué
Physics , 2009, DOI: 10.1103/PhysRevD.80.124045
Abstract: Two complementary techniques are developed for obtaining the asymptotic form of gravitational-wave data at large radii from numerical simulations, in the form of easily implemented algorithms. It is shown that, without extrapolation, near-field effects produce errors in extracted waveforms that can significantly affect LIGO data analysis. The extrapolation techniques are discussed in the context of Newman--Penrose data applied to extrapolation of waveforms from an equal-mass, nonspinning black-hole binary simulation. The results of the two methods are shown to agree within error estimates. The various benefits and deficiencies of the methods are discussed.
