Engineering（科研） 2010年第9期2卷 733-739页

Thermal stresses in the combustor of gas-turbines are computed using non-dimensional parameters. Buckingham pi theorem was used to arrange the listed relevant parameters into non-dimensional groups. In testing the validity of the functional relation of the non-dimensional independent parameters, use is made of the prevailing temperatures of the combustor in operation. A computer program was used to enhance computations. The results showed an interesting way of influencing the axial stresses. To reduce stresses in gas-turbine combustors, a method of varying the independent parameter that is of radius ratio oriented and thickness dependent was adopted. This showed a reduction of the axial stresses to minimal levels using the parameters. Plots were made and a point of inflection that manifested itself in the presentation of the axial stress function was further investigated upon. It turned out to be a point of abnormal stress level and out-of-trend temperature profile. The use of non-dimensional consideration proved adequate in the computation of axial stresses. The results showed a 2 percent difference from existing values of stresses got from a transient thermal loading of a combustor.

A rapid and sensitive ultra-performance liquid chromatography–tandem mass spectrometry（UPLC–MS/MS） method was developed and validated for the estimation of 17-desacetyl norgestimate in human plasma using solid-phase extraction technique. 17-desacetyl norgestimate d6 was used as the internal standard. Simple gradient chromatographic conditions and mass spectrometric detection enabled accurate and precise measurement of 17-desacetyl norgestimate at sub-picogram levels. The proposed method was validated for a linear range of 20–5000 pg/m L with a correlation coefficient Z 0.9988. The intra-run and inter-run precision and accuracy were within 10%. The overall recoveries for 17-desacetyl norgestimate and 17-desacetyl norgestimate d6 were 96.30% and 93.90%, respectively. The total run time was 4.5 min. The developed method was applied for the determination of the pharmacokinetic parameters of 17-desacetyl norgestimate following a single oral administration of a norgestimate and ethinyl estradiol0.250 mg/0.035 mg tablets in 35 healthy female volunteers.

Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians.

微控制器环境要求在尽可能小的封装里实现最多的通用I／O。在微控制器尺寸和成本的限制下，M4K内核内部不支持指令高速缓存（I—cache）或数据高速缓存（d—cache）的标准功能。但MIPS32 M4K内核所具有的一些特点使其非常适用于微控制器应用领域。这就涉及到本文重点讨论的一个内容——SRAM接口，这是MIPS32 M4K内核的一个标准功能。

传统的三维地震、水平井钻井和水力压裂技术是开发非常规油气资源的有效手段,应用于复杂油气藏识别与描述的3C-3d、9C-3d等地震技术能够有效降低勘探风险.在美国阿巴拉契亚盆地进行的裂缝性页岩气储层研究结果表明：利用纵波和转换横波联合解释技术能够提高断裂解释和天然裂缝性页岩储层预测的精度.基于纵波、转换横波联合反演提取纵横波速度比、密度等属性参数并验证了裂缝预测成果,进而提高了天然微裂缝储层“甜点”预测的准确性和可靠性.
