abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
Diesel-operated Load Haul Dumper (LHD) vehicles are commonly used in underground coal mines. Despite their value as utility vehicles, the main drawback of these vehicles is that they generate diesel particulate matter (DPM), a known carcinogenic agent. In this work, an attempt is made to model DPM flows generated by LHDs in an underground coal mine environment for different DPM flow and intake ...
This paper presents a detailed account of computational fluid dynamics (CFD) simulations undertaken to investigate the influence of intake (ventilation) air velocities on the flow patterns of diesel particulate matter (DPM) generated by a man-riding vehicle operating in a straight rectangular cross section tunnel in an underground coal mine. The simulation results are validated against an earli...
بیماری های قلبی- عروقی بیشترین میزان مرگ و میر را در میان بیماری ها داراست که اهمیت محدودیت های درمان کنونی را در روش های رایج درمانی آشکار می سازد. نقش داربست های سه بعدی برای درمان انفارکتوس قلبی توسط داربست هایی طبیعی که تشابه بیشتری به بافت های مورد را دارند به نظر می رسد که جهت استقرار مجدد ماتریس خارج سلولی آسیب دیده قلب مناسب ترند. در این مطالعه، ما ویژگی های in vito و in vivo یک داربست ...
Elemental carbon (EC) is used as a surrogate for regulating the exposure to diesel particulate matter (DPM) of underground metal/non-metal miners. EC was chosen as a surrogate because EC is selective to DPM and is a major component of DPM. Using EC as a surrogate also gives one the advantages of no sampling artifacts and being able to sample at all locations in the mine. Currently, EC represent...
Dipyridamole (DPM) enhanced the sensitivity of human ovarian carcinoma 2008 cells to etoposide (VP-16) producing a 5.5-fold reduction in 50% inhibitory concentration at a DPM concentration of 20 microM. This interaction was shown to be truly synergistic by isobologram and median effect analysis. DPM increased the steady-state VP-16 content of 2008 cells; a DPM concentration of 4 microM increase...
گسسته سازی مسئله در بسیاری از روش های بدون شبکه به معادلات انتگرالی منجر می شود، که حل آنها نیازمند انتگرال گیری عددی و معرفی نقاط گوس و وزن های مربوط همراه با شبکه بندی است. اما در میان این روش ها، روش بدون شبکه ی کمینه ی مربعات گسسته می تواند مراحل انتگرال گیری برای محاسبه ی ماتریس ضرایب را حذف کند و در عین سادگی، دقت بالا، و هزینه ی محاسباتی پایین، در مفهوم واقعی بدون شبکه باشد. هدف از این پ...
Genetic Dissection of the Neural Circuitry Underlying Memory Stability in Drosophila: A Dissertation
Understanding how memory is formed requires looking beyond the genes involved to the neural circuitry and temporal aspects of memory. In this dissertation I have focused my investigation on Dorsal Paired Medial (DPM) neurons, two modulatory neurons essential for memory in Drosophila. DPM neurons highly express the amnesiac (amn) gene, which encodes for a putative pre-pro-neuropeptide. amn funct...
90Sr activity was measured with the full spectrum DPM (FS-DPM) counting method after plotting the quench correction curves of 90Sr and 90Y, and the FS-DPM method was applied to determine the 90Sr in liquid waste samples. The optimum regions of 90Sr and 90Y were set for measuring 90Sr with the dual label DPM (DL-DPM) method. The direct measurement of purified 90Sr with spectrum unfolding techniq...
