试验表明,方解石等非金属材料经短时、低压渗氢处理后显微硬度、晶格常数均明显减小,这意味着氢扩散可引起非金属材料的强度下降、材料弱化.地球内部各种化学反应所生成的氢气及地球形成时其内部所聚集的氢气都要沿断裂带向上迁移,逸出... 详细信息

试验表明,方解石等非金属材料经短时、低压渗氢处理后显微硬度、晶格常数均明显减小,这意味着氢扩散可引起非金属材料的强度下降、材料弱化.地球内部各种化学反应所生成的氢气及地球形成时其内部所聚集的氢气都要沿断裂带向上迁移,逸出,在其逸出的同时将明显降低岩石、岩层的强度,使断层在低构造应力作用下有可能发生断裂.氢气浓度异常从现象上看是被动的、断层活动的反映,而氢气逸出本身对断层运动却有能动的诱发作用.

在亚拉巴马州西南部,侏罗系斯马科弗组藻类碳酸盐泥岩是中生界储集层中原油和凝析油的主要生油岩。这一解释依据的是一些页岩(诺夫利特组、海恩斯维尔组、特里尼蒂群、塔斯卡卢萨群)和碳酸盐岩(斯马科弗组)样品中的原油、凝析油和有机... 详细信息

在亚拉巴马州西南部,侏罗系斯马科弗组藻类碳酸盐泥岩是中生界储集层中原油和凝析油的主要生油岩。这一解释依据的是一些页岩(诺夫利特组、海恩斯维尔组、特里尼蒂群、塔斯卡卢萨群)和碳酸盐岩(斯马科弗组)样品中的原油、凝析油和有机质的地球化学分析结果。潜在的和可能的生油岩分别赋存在塔斯卡卢萨群和斯马科弗组中。斯马科弗组碳酸盐岩的可抽提有机质,其分子和同位素特征类似于侏罗系石油。尽管亚拉巴马州西南部的侏罗系原油与凝析油具有相似的成因,然而其成分由于热成熟度和有机相/岩相的不同而变化很大。有机相反映了不同盆地中生油岩的不同沉积条件。密西西比因蒂里厄索尔特盆地(以下简称为MIS盆地)以较连续的海洋至超盐度环境为特征,而马尼拉和科尼卡海湾周期性地具有较低的酸度,岩屑和陆源有机质有较大量的输入。亚拉巴马州西南部休罗系岩石中的石油和有机质,显示出一系列热转变作用。储集层中烃的天然气含量随埋藏深度和温度的增加而增高。在温度高于130℃的一些储集层中,凝析油在同位素组成上富含重硫——显然来源于侏罗系蒸发盐的硫酸盐热化学还原作用。这一作用还导致了该天然气中H_2S和CO_2含量的增高以夏凝析油中饱和烃含量的减少。硫酸盐的热化学还原作用可能取决于储集岩的矿物成分?

聚束滤波方法的基本原理，包括信号与噪音模型、设计准则和所获得的聚束滤波器．本文所用的自适应聚束滤波器是根据具有参数化的动校正量、振幅及相位随偏移距变化（ＭＶＯ、ＡＶＯ及ＰＶＯ）的一次反射和多次反射信号模型而设计的．但在实际应用中ＰＶＯ通常不能得到证实．结果分析能为进一步的从ＡＶＯ及ＰＶＯ获取岩石类型信息的专题研究提供资料．人工合成资料的例子给出了参数化的自适应聚束滤波的实施细节和所设计滤波器的响应特性．实际资料的例子表明数据自适应聚束滤波在叠前共中点道集地震多次波消除上比Ｒａｄｏｎ变换方法更灵活、有效．类似于其它叠前处理过程，自适应聚束滤波的优越性在信噪比较高的资料上体现得最为明显．

Open Journal of endocrine and Metabolic Diseases 2014年第7期4卷 197-210页

Background: Glucagon-like peptide-1 (GLP-1) is an incretin hormone with insulinotropic properties that regulates glucose metabolism. GLP-1 receptors are the most extensively key modulators of lipid and glucose homeostasis. They are predominantly expressed in adipose tissues, some non adipose tissues including heart, kidney, spleen, and all relevant cells of the vasculature: endothelial cells, smooth muscle cells, and macrophages. The vascular distribution suggests their involvement in the control of cardiovascular function. Objective: The present experiment was designed to study the effect of sitaglipten alone or in combination with captopril on blood pressure, antioxidant enzymes, vascular reactivity and cardiac hypertrophy in NG-nitro-L-arginine methylester (L-NAMe) induced hypertension in rats. Methods: One hundred male albino rats weighing from 150 - 200 g were included in this study. Rats were divided into two main groups. Group I, (20 rats) served as a control group for group II, and received 1 ml of physiological saline (0.9%), orally for seven weeks. Group II: hypertensive group, (80 rats) was given daily L-NAMe in a dose of 40 mg/kg orally for seven weeks. Rats were further subdivided into A, B, C, and D, each of 20 rats. Group-A, received 1 ml of distilled water daily orally for six weeks, starting one week after L-NAMe administration. Groups B, C and D were treated with daily sitaglipten (10 mg/kg ***. orally) and captopril (100 mg/kg ***. orally), alone or together for six weeks. Blood pressure, serum tumor necrosis factor-α (TNF-α), body weight (BW) and heart weight (HW) were measured. Malondialdehyde (MDA) and reduced glutathione (GSH) were estimated in cardiac tissues. Thoracic aorta was isolated and the aortic rings were allowed to achieve maximal tension by cumulative addition of phenylephrine (Pe) (10-9-10-5 M) to the bath solution. Results: Sitaglipten and captopril, alone or together produced significant decreases in blood pressure and TNF-α. H

Open Journal of Nursing 2013年第5期3卷 404-413页

Although a great many qualitative descriptions of the experience of having breast cancer exist, they overwhelmingly represent experiences of women in Western cultures and are based on assumptions that stem from Western individualism. This study explores and describes cultural models shared by a group of non-Western women, South Koreans, in reference to female breasts and breast cancer. The hermeneutic phenomenology-grounded qualitative study was conducted with 40 Korean women, between 23 and 81 years of age, half of whom were breast cancer survivors. The analysis elicited two cultural models, both characterized in terms of physical relationships to others (as opposed to the woman’s individual or independent view of her body): a breast-feeding mother to a child and an attractive wife to a husband. Female breasts are interpreted as a medium that connects women to roles as mothers and wives. Breast cancer can lead women to detach from their previous relational and role-oriented identities. Cultural traditions, cultural concepts, and culture-related health beliefs in Korea are interwoven deeply in the women’s stories about breasts, as a gendered organ, and its disease. The findings suggest that understanding indigenous cultural models should precede any supportive breast cancer care for women from non-Western cultural backgrounds.
