Page Numbers : Sch. Bull.; 2016, 2(6): 333-337
DOI : 10.21276/sb.2016.2.6.5
Abstract: The thickness, lateral connectivity and boundary position of the thin layer are increasingly becoming the focus of lithologic seismic exploration, but the recent progress on thin layer have less systematic summary. Therefore, four aspects of thin layer research relating to research subject, forward modeling method, time-frequency analysis method, thickness prediction method are summarized. The following conclusions show that spectrum variation regularity of reflected wave is the key to thin layer analysis. A quantitative relationship between the peak frequency or notches frequency and thin layer thickness has already established. Wave equation forward modeling can reflect the dynamic characteristics of seismic wave in the propagation process, so the simulated wave field information is more rich and real. Analytical tools of reflected wave field are from time domain, frequency domain analysis to the time-frequency analysis and temporal characteristics of the reflected wave spectrum are took more attention. Thus wave field characteristics of thin layer are gradually evolved from a simple qualitative analysis to quantitative prediction direction.

Different types of rock have different microflow characteristics in which displacement efficiency is different. The displacement efficiency of dissolve mind intergranular pore is high, and the dissolved pore is low. Heterogeneity is the main internal factors affecting displacement efficiency, and physical properties and pore throat impact on displacement efficiency weakness. Of the external factors, water injection pressure and injection water multiple have a large influence on displacement efficiency compared to multiple injections. Improvements to the water injection pressure will have a better effect on improving oil displacement efficiency.

The physical properties of Chang 81 layer under different subfacies and different sources are contrasted. The result shows that the reservoir property of delta plain in Chang 8layer is better than that of delta front, and the reservoir property controlled by the provenance from northwest is better than that controlled by the provenance from the northeast. The favorable reservoirs of Chang 8 member are predicted, and it is considered that the reservoir in the northwest of Jiyuan Oilfield has great hydrocarbon potential.

Abstract: The research on the characteristics of oil migration mechansim and pathway of oil migrating from K2qn1 source rocks down-ward to F, Y oil layer in Sanzhao Depression shows that the source faults of F,Y oil layer should be the T2 faults. The upper part of those faults disappeared in K1qn1source rocks, and the main faults just cut through T2, along from T2 to T3, from T2 to T4 and from T2 to T5 and distributed in the whole depression. The migration distance of oil downward from K1qn1 source rocks in Sanzhao Depression is mainly influenced by the difference between ancient overpressure of K2qn1 source rock and flow resistance during the process of migration downward and also influenced by combination way of faulted sandstone and mudstone in F, Y oil layer. It makes the deviation of actual downward migration distance with the theoretical migration distance. The actual distance of oil downward from K2qn1 source rocks is 300 m, and the high-value area mainly distributed in oil fields. The control factors of source faults to oil accumulation and distribution are given. The development area of source faults controls the area of oil distribution. The development degree of source faults controls oil downward migration distance. The high fault blocks nearby source faults are favorable for oil accumulation in F, Y oil layer. The distance to source faults controls the productivity of oil wells.

Effect of Thiamine on Fasting Blood Glucose Level of Non-Diabetic and Diabetic Albino Rats
Abstract: The worldwide prevalence of diabetes has risen dramatically over the past two decades from an estimated 30 million cases in 1985 to 382 million in 2013. The traditional anti diabetic drugs have several drawbacks in long term use. Thiamine is a member of the vitamin B family. Thiamine is necessary for normal insulin synthesis and secretion. So it may be beneficial in diabetic persons where insulin synthesis and secretion are disturbed. Albino rats used in this study was divided into four groups; six rats in each group. The groups were normal control, diabetic control, non-diabetic rats treated with thiamine and diabetic rats treated with thiamine. Diabetes was produced by intraperitoneal injection of Streptozotocin in the dose of 60 mg/kg. Fifteen minutes before streptozotocin administration nicotinamide was administered 120 mg/ kg intraperitoneally. Thiamine was given to the respective group for a period of 6 weeks. Fasting blood glucose was estimated at the end of every week. In non-diabetic rats thiamine showed no significant effect in lowering fasting blood sugar level. In diabetic albino rats thiamine normalized fasting blood glucose in six weeks. Thiamine does not affect the fasting blood glucose level of the normal rat but this effect was found significant in streptozotocin induced diabetic albino rats in six weeks period.

Page Numbers : Sch. Bull.; 2016, 2(6): 430-435
DOI : 10.21276/sb.2016.2.6.31
Abstract: This article is a culmination of a study examining the legal and institutional framework that Kenya has for regulating adult content in broadcast media. In that regard, the children’s rights in relation to protection from broadcast content as encapsulated in the Constitution of the republic of Kenya is considered. The relevant international conventions that Kenya has ratified and how local laws seek to protect children from potentially harmful broadcast media is of paramount interest. The researchers draw from the Kenya Information and Communication (Amendment) Act 2013, the Kenya Information and Communication (Broadcasting) Regulations 2009 which are still relevant to the new aforementioned Act, the Media Council of Kenya 2013 and the Children Act of Kenya. The objective is to examine various regulations and laws and how they protect children from potentially harmful broadcast content in Kenya. The findings establish various laws in Kenya providing for the regulation of broadcast media, which are implemented by two media regulatory bodies: Media Council and Communications Authority of Kenya. The two regulatory bodies are the two parallel public complaints systems to which Kenyans can launch complaints regarding media content. The writers conclude that as things are currently, children in Kenya face a dangerous future in terms of their morals unless measures are put in place to watchdog the fourth estate.
