Abstract: Rock brittleness is one of the key parameters to be considered in the exploration and development of unconventional oil and gas reservoirs. The Young's modulus and Poisson's ratio method based on rock elastic parameters of normalized is currently widely used for seismic prediction of brittle rock evaluation technology, but the results could be severity affected by parameters of normalized. The Young's modulus and Poisson's ratio as the evaluation index of brittleness, and the scale of large quantity of rock mechanics experiment, has increased the reliability of brittle rock discrimination, this paper re-division of brittle category, focusing on analyzing the effects of minerals and rocks on the brittle zone, and explore the brittleness index calculation method and formula, to play a reference role for the number of period of J depression Permian Lucaogou Formation compact rock brittle prediction.

Abstract: Medical records of infants and children evaluated for hypoglycemia, in the period January 1989 and December 2014, were retrospectively reviewed. Data included age, sex, maternal history, dietary history and drug intake, concomitant illness, clinical presentation, and results of relevant laboratory and radiological investigations. Glycogen storage disease, metabolic disorders, and hormonal disorders were excluded as recommended. Fifty-two patients were born in or referred to King Khalid University Hospital were evaluated. Wide spectrum of causes was noted with persistent hyperinsulinemic hypoglycemia of infancy (PHHI) in infants, while ketotic hypoglycemia was the commonest beyond infancy. The frequency and aetiological pattern of hypoglycemia is variable with persistent hyperinsulinemic hypoglycaemia of infancy (PHHI) was the commonest encountered in 10 (19.2%) infants, and while ketotic hypoglycemia was the most common cause of hypoglycemia in children beyond infancy found in 9 (17.3%) patients.

N/A
Abstract: According to the test of oil exploration, the production of oil wells, indoor tests and logging data, oil-water distribution law can be studied. The results show that the oil and water have the zoning feature in the plane, for specific performance, the oiliness of the east is high, the oiliness of the center is poorer, and the oiliness of the west is good. Beside, the oil and water have the characteristic of differentiation in vertical, and the layers which full of oil are from PⅠ6 to PⅠ8.The main controlling factor of the distraction of oil and water includes: faults and structural location decide the plane characteristic of oil and water. In the background of facies of delta front, underwater distributary channel sandbody is the high-quality reservoir of Putaohua reservoir.

N/A
Abstract: The purpose of the article is to examine the relationship between news content tabloidization and political polarization in the standard newspaper in Kenya. The need for this study was prompted by the fact that the definition of tabloidization and its causes have been limited and non-inclusive enough. While not disputing the fact that tabloid content sells more than elitist journalism, this paper seeks to explain how political polarization can induce tabloidization of the national news. Tabloidization of news content has been restricted to mean only the placement of personal news, scandal, human suffering, celebrities and sport, all of which is categorized as soft news, in a space reserved for national political and economic news which is categorized as hard news. This study broadens the concept of tabloidised content to include ambivalent opinion, personalization of official conflict and the use of the public discussion forum approach to polemize concrete facts. The study links political polarization in Kenya to the increased prevalence of this phenomenon. The theoretical perspective used as the background of the study is the agenda setting theory and Harbemas’ public sphere concept .The methodology involved the qualitative analysis of selected news items of The Standard newspaper representing a time period ranging from 1995 when there was a relative political cohesion in the Kenya, to 2015, when the country is politically polarized. The study succeeded in linking political polarization to an increase in tabloidization of news content in The Standard newspaper.

Abstract: Oil-water relative permeability curve is used to describe two-phase fluid in reservoir porous media of non-linear percolation in the only way. Low permeability reservoir of oil and water relative permeability curves with high permeability reservoir of oil-water relative permeability curves of different features. Specific performance: the high bound water saturation, residual oil saturation is high, narrow range of oil-water two-phase flow, with the decrease of the saturation of oil phase, oil phase permeability decreases rapidly, and soon fell to zero, to form a high residual oil saturation and water flooding oil recovery rate is very low, and the aqueous phase effective permeability increases very slowly, resulting in low permeability reservoir well with increase of water content, the produced fluid index drop Low liquid production is very low. Fuyu oil layer in the study area mainly belong to low porosity and ultra low porosity and super low permeability non permeable reservoir, through the research found the oil-water two-phase flow characteristics is more complex, with middle high permeability reservoir and low permeability reservoir layer had greater differences.

Page no Sch. Bull.; 2016, 2(3): 146-148 |
N/A
Abstract: We are going through a time period in which scholars have been developing different modernity discourses. For example, one can readily see how modernity was formed as a discourse by the thinkers of “the West”. That is why several scholars from “the rest” of world have always criticized the Western single path to modernity. Without a doubt, Sayyid Jamal al-Din al Afghani was one of the leading figures of his time criticizing West-centric modernity discourse in his works. However, one should be careful about the conditions of his time, worldview, interest, and demand. That is because there is always a risk of misunderstanding if one isolates a scholar from his or her maturing social conditions. Therefore, this article is going to examine a possibility of alternative modernity searched by Sayyid Jamal al-Din al Afghani by focusing on his major works and the social context from which he run his studies.

Abstract: Fased the circumstances of less influence factors analysis on the seismic reflection characteristics, this article obtains from the angle of forward, forward model is established for the analysis of reservoir thickness, sandstone superimposed relationship, sandstone thickness and interlayer thickness on the influence of seismic reflection characteristics. The reservoir thickness and thin-sandstone have little influence on the characteristic of seismic reflection, thick sandstone in seismic wave energy is strong, with thick sand wave up degree is more obvious. Interlayer thickness and positively correlated to the influence degree of the seismic reflection characteristics, when the insulation layer thickness more than 30 meters, no longer have an impact. After the conclusion is that analysis of seismic reflection characteristics and the relationship between the underground sand bodies, providing certain guidance to predict channel sand body.

Abstract: Chronic smoking adversely influences the prognosis of nephropathies. The objective of this study was to the relationship between renal damage and chronic smoking through parameters can bring a clear vision about kidney status.This study was a case control study, was conducted in Khartoum state,Microalbuminuria is defined as excretion of 30–300 mg of albumin per 24 hours (or 20–200 mcg/min or 30–300 mcg/mg creatinine) on 2 of 3 urine collections. Microalbuminuria is caused by glomerular capillary injury and so may be a marker for diffuse endothelial dysfunction. According to Steno hypothesis, albuminuria might reflect a general vascular dysfunction and leakage of albumin and other plasma macromolecules such as low density lipoproteins into the vessel wall that may lead to inflammatory responses and in turn start the atherosclerotic process. Apparent healthy subjects were randomly participate in this study, A fifty (50) subjects chronic smoker subjects were involved in this study and other ninety four (94) ones were considered as control group, statistical analysis for chemical results of creatinine, microalbuminuria (MIA) and calculated ACR (albumin/creatinine ratio) revealed significant different in creatinine in smokers group when compared to non-smokers group, and strongest relationship between creatinine and duration of smoking, and between MIA and ACR with number of smoked of packs per day.
