A total of 6 oil samples were systematically selected from six Asmari Reservoir wells in the Cheshmeh-Khush Oilfield for geochemical evaluation of the hydrocarbon system,based on reservoir geochemistry and oil *** investigation of the distribution patterns of normal alkanes and tricyclic and tetracyclic terpanes along with characteristic biomarkers of the depositional environment and sedimentary facies,indicated that the source rock of the studied hydrocarbons was deposited in a reducing aquatic environment with a low input of terrigenous material and predominantly carbonate lithology derived from organic algal *** studied oil samples exhibited moderate maturity,as was further confirmed by the parameters extracted from the light *** clustering based on different biomarker parameters indicated the presence of two oil ***,the application of branched and cyclic compounds in the light hydrocarbons(C5–C11)to evaluate lateral continuity of the Asmari reservoir further supported the presence of the two oil *** evidence proved the presence of a NE–SW trending fault separating wells X5 and X6 from the other wells in the *** other wells across the field,good lateral reservoir continuity was observed,despite the presence of faults on the northern and southern plunges of the structure.

On Non-standard Hilbert Functions

Algebra Colloquium 2018年第1期25卷 71-80页

作者： Amir bagheri rahim Rahmati-Asghar Marand Technical Coflege University of Tabriz Tabriz Iran School of Mathematics Institute for Research in Fundamental Sciences (IPM) Department of Mathematics Faculty of Basic Sciences University of Maragheh

. Let S = k[x1,..., xn] be a non-standard polynomial ring over a field k and let M be a finitely generated graded S-module. In this paper, we investigate the behaviour of Hilbert function of M and its relations with lattice point counting. More precisely, by using combinatorial tools, we prove that there exists a polytope such that the image of Hilbert function in some degree is equal to the number of lattice points of this polytope.

页岩气评价方法及关键参数研究表明,仅靠技术指标来寻找地质甜点并不能实现页岩气的商业经济开发。通过将总有机碳含量、镜质体反射率等技术指标与内部收益率、投资回收期等经济指标相结合,提出一套经济指标和技术指标相结合的研究方法,用以筛选页岩气未开发区的最佳技术经济开发甜点。采用该方法通过总有机碳含量、镜质体反射率、有效储集层厚度和含气量等参数筛选21个地质甜点。再基于类比研究法,以压力梯度、黏土矿物含量、埋藏深度等参数为类比依据,选择Eagle Ford页岩为类比对象,提取采收率和生产曲线两项指标,估算研究区的技术可采储量。在此基础上,结合内部收益率、投资回收期等经济指标评价地质甜点的经济性。应用这套多参数综合评价方法,对伊朗卢雷斯坦地区白垩系页岩气储集层S_(1)层和S_(2)层进行评估,确定该区域的最佳技术经济开发甜点。结果表明,在净现值取其P_(10)值(累计概率10%时对应的参数值)的情况下,技术可采储量和经济可采储量总量分别为7875×10^(8)m^(3)和4306×10^(8)m^(3),有11个地质甜点具有商业开发价值,其中1号甜点价值最高,净现值为35×10^(8)美元。

Continental Trace Fossils in the Semnan Area (Northern Iran)

引用

Open Journal of Geology 2013年第2期3卷 54-61页

作者： Mousa bagheri Sadat Feiznia Mehran Arian rahim Shabanian rahim Mahari Geology Department Faculty of Science Science and Research Branch Islamic Azad University Tehran Iran

Continental ichnology has been taking an ever increasing importance in stratigraphy. In this paper, Continental Trace Fossils in Semnan area have been studied. Semnan Province is one of the 31 provinces which is located in the north of Iran. In the East of Semnan City, Quaternary deposits occupy about 93% of the surface area, of which the Alluvial represents one of the most important geomorphological features in the area. Nevertheless, the outspread ichnological studies in Semnan City have received lesser attention in Continental Trace Fossils. Based on the systematic ichnology, 6 trace fossils are distinguished, namely Celliforma isp, Coprinisphaera isp, Palaeophycus tubularis, planolithes isp, Tombownichnus plenus, and Skolithos isp. The existence of Rhizoliths along with the tetrapod footprints and the survey of lithofacies all indicate that the trace fossils are related to Coprinisphaera ichnofacies. Based on ichnological and sedimentary facies analysis, the Continental Trace Fossils, in the study area, are located in the flood plain, point bar, and playa environment.

Does delayed gastric emptying shorten the H pylori eradication period? A double blind clinical trial

World Journal of Gastroenterology 2006年第39期12卷 6310-6315页

AIM: To evaluate the gastric emptying inhibitory effects of sugar and levodopa on H pylori eradication period. METHODS: A total of 139 consecutive patients were randomized into 6 groups. The participants with peptic ulcer disease or non-ulcer dyspepsia non-responding to other medications who were also H pylori-positive patients either with positive rapid urease test (RUT) or positive histology were included. All groups were pretreated with omeprazole for 2 d and then treated with quadruple therapy regimen (omeprazole, bismuth, tetracycline and metronidazole); all drugs were given twice daily. Groups 1 and 2 were treated for 3 d, groups 3, 4 and 5 for 7 d, and group 6 for 14 d. Groups 1 to 4 received sugar in the form of 10% sucrose syrup. Levodopa was prescribed for groups 1 and 3. Patients in groups 2 and 4 were given placebo for levodopa and groups 5 and 6 received placebos for both sugar and levodopa. Upper endoscopy and biopsies were carried out before treatment and two months after treatment. Eradication of H pylori was assessed by RUT and histology 8 wk ***: Thirty patients were excluded. Per-protocol analysis showed successful eradication in 53% in group 1, 56% in group 2, 58% in group 3, 33.3% in group 4, 28% in group 5, and 53% in group 6. Eradication rate, patient compliance and satisfaction were not significantly different between the groups. CONCLUSION: It seems that adding sugar or levodopa or both to anti H pylori eradication regimens may lead to shorter duration of treatment.
