Abstract: Gallstones disease is one of the most prevalent gastrointestinal diseases with a substantial burden to healthcare systems that is supposed to increase in ageing populations at risk. Gallstones disease is one of the major surgical problems in the Sudanese population. The aim of this study was to measure serum lipids profile in Gall stone diseases, and also to evaluate the risk and demographic factors.This study was case control hospital bases study, and conducted in Khartoum teaching hospital and Ibin Sina hospital, Khartoum state. During Oct 2008 to Oct 2009. 65 Sudanese patients with gall stones which are confirmed by abdominal ultrasound scanner and underwent cholecystectomy and 50 healthy persons as a control group (matched age sex)have been studied. Serum of fasting total cholesterol, triglycerides, HDL-cholesterol and LDL-cholesterol were measured using spectrophotometric methods. Results revealed that the high incidence of gallstones was more frequently among females(83.9%) relatives to males(16.1%)giving female to male ratio 4.9:1.The most affected age groups were 51-60 years (32.31%) and 41-50 years (30.77%).The majority of patients 34 (52.31%) were obese and their body mass index(BMI) 25-30.Comparison of serum lipid profile between patients and controls groups showed that the levels of serum total cholesterol and LDL-C in patients were slightly higher than that of the control group but there was no significant variation in total Cholesterol and LDL-C (p>0.05) . Furthermore, It is found that there is Highly significant difference between patients and controls groups in serum triacylglycerol and HDL-C(p<0.05) . Serum total cholesterol level of patients with CS was high compared to that of other types of patients, while the level of serum HDL-C was low of patients CS. Pigment stone (PS) was found to be the commonest comprising, followed by mixed stone and cholesterol stone. Biochemical analysis of serum lipid profile between patients and controls groups revealed significantly increase of serum triacylglycerol and HDL-C levels. Serum total cholesterol level of patients type one was high compared to that of two types of patients, while the level of serum HDL-C was low of patients type one.

Abstract: Development is an important term in most all perspective. There so many stakeholders, agencies, institutions are responsible, form community development. Information is treated as most powerful term for development. As information is required in all most all the places and institutions, thus proper and information richness helps a community or a society for true development many ways. Information Science is responsible for several information related jobs, which including information collection, selection, organization, processing and management. Information and its proper availability many ways possible healthy information science practice and that is indirectly responsible for community Development. This paper reports knowledge of Information Science and how it is essential for better information system building. Paper also mention that community and several development how related with information science. Several facets reported in this paper mainly undertaken in SOCSAT and Raiganj University and also will be incorporated in the doctoral thesis of the main researcher.

Page Numbers : Sch. Bull.; 2016, 2(2): 68-71
DOI : N/A
Abstract: Reservoir geological model is the core of the geological model of the reservoir, is the specific characterization of reservoir characteristics and heterogeneities in the three-dimensional spatial distribution and change. Reservoir modeling is actually establish reservoir properties of reservoir parameters characterizing the three-dimensional spatial distribution and change models. Reservoir parameters include porosity, permeability and oil saturation, reservoir thickness. The purpose of the establishment of reservoir parameter model is through quantitative research on porosity, permeability and thickness of the reservoir, precisely defined spatial location and distribution of favorable reservoir, which directly provide direct the development and adjustment of oilfield development plan geological basis.

Abstract: This study examines the effect of exchange rate on balance of payment in Nigeria for the period of 1989-2013. The data used for this study was obtained from the publications of Central Bank of Nigeria (CBN) and also from National Bureau of Statistics (NBS). Ordinary Least Square method was implored for data analysis with time series statistical package of econometrics. Exchange rates, import, export and interest rate where the independent variables used while balance of payments stands as the dependent variable. The researcher also used those macro-economic variables to ascertain their contribution to both positive (favorable) and negative (unfavorable) balance of payments which foreign exchange movement always determines. The result shows that an increase in exchange rate will result in a decrease in BOP (unfavorable), while export and interest rate has positive effect on balance of payment unlike import that contributes negative effect on balance of payment (unfavorable) as it increases.

Characteristics of Micro-Pore Structure of Tight Sandstone Reservoir: A Case Study from ImsarSag Tight Oil Reservoirs
Page Numbers : Sch. Bull.; 2016, 2(2): 78-80
DOI : N/A
Abstract: Jimusaer sag Lucaogou Formation tight oil reservoir lithology is changeable, diverse mineral elements and clastic rock and carbonate rock of the transitional rocks. Dense oil in the region to the source of various storage and source reservoir interbedded characteristics, forming a good source reservoir relationship was set up. In this paper, the study area reservoir pore types in intergranular pore, mainly. Secondly, dissolution pores and micro cracks. According to pressure mercury data can be reservoir pore structure is divided into micro fine throat and throat, but overall has pore throat radius is too small, poor connectivity, strong microcosmic heterogeneity characteristics.

Abstract: The Chao yang gou oil field seismic data acquisition has been basically completed, as the development of the oilfield in recent years, the sand body in the Outside enlarge develop worse, urgently need to use the geophysical data and logging data to describe the tentonic characteristics and fault distribution of the research area. This way can enhance prediction accuracy of the fault and sand body. Build a set of Prediction method and train of thought to suit Chao yang gou oil field geological characteristics. This paper use the geological structure data and logging data to describe the reservoir characteristics of the research area. This paper has important significance for the guide the oilfield development adjustment.

Abstract: Fuyu oil layer in Toutai oil field has entered the development stage, in order to improve the recovery efficiency, needs to understand the underground fine geological conditions, and the study of fine sedimentary microfacies provides a solid foundation for the geological study. Through core and thin sheet material observation, combined with logging and experiment data analysis research, show that this area belongs to the delta plain, delta front and meandering river sub phase, and identified a further twenty-three kinds of microfacies . Analysis of the important sedimentary unit F I 3a, F I 5a, F I 8a, F II 5a sedimentary microfacies and plane sedimentary characteristics and logging facies model, which is conducive to a correct understanding of the favorable facies belt and distribution characteristics, tapping the potential of the remaining oil laid the foundation. F I 5a and F I 8a sedimentary units are delta plain subfacies phase. F I 3a and F II 5a sedimentary units are delta front subfacies.

DOI : N/A
Abstract: Seismic sedimentology is the subject that using seismic information to study sedimentary rocks and the formation process，it is a new frontier science, which is a new frontier of seismic stratigraphy and sequence stratigraphy. Seismic sedimentology the subject which is using seismic methods to study sedimentary rocks and the formation process, the research method mainly has 90 degrees of phase transition and formation slicing technology. 90 degree phase transformation makes seismic facies with lithology Stratigraphic Significance；stratigraphic section is the plane distribution of the depositional system of the stratigraphic unit, which is used to study the stratigraphic units in each of the strata. In February 2005, the international conference held in the United States of Houston Seismic Sedimentology，following seismic stratigraphy and sequence stratigraphy, seismic sedimentology as a new subject has attracted more and more attention.
