برای تصمیمگیری به منظور جلوگیری از شورشدن و زه دار شدن تدریجی اراضی، نیاز به شناخت منشاء، حدود و میزان شوری و اطلاعات کمی و بهنگام از منطقه میباشد. با استفاده از پردازش و تفسیر تصاویر ماهوارهای و تحلیلهای منطقهای دادههای آماری مانند هدایت الکتریکی و تغییرات تراز آبخوان میتوان به شناسایی مناطق شور و زهدار پرداخت. در تحقیق حاضر با تولید نقشههای کاربری فعلی و قدیمی اراضی و بررسی کمی پارا...
PURPOSE Testicular microlithiasis (TM) is an uncommon pathologic condition that is commonly diagnosed by scrotal ultrasonography. Indirect evidence suggests that this syndrome may be associated with an increased risk of testicular malignancy and infertility. MATERIALS AND METHODS A total of 1,439 patients undergoing scrotal ultrasound during a 6-year, 5-month period (January 2003 to May 2009)...
Recent studies suggest that wave motions of the tectorial membrane (TM) play a critical role in determining the frequency selectivity of hearing. However, frequency tuning is also thought to be limited by viscous loss in subtectorial fluid. Here, we analyze effects of this loss and other cochlear loads on TM traveling waves. Using a viscoelastic model, we demonstrate that hair bundle stiffness ...
AIMS Glycan expression was compared in glaucomatous trabecular meshwork (TM) and normal TM in order to determine any differences which may reflect pathological changes underlying primary open angle glaucoma (POAG). METHODS Resin embedded TM from trabeculectomy specimens from 15 eyes with POAG and from 12 eyes with normal anterior segments were probed with a panel of biotinylated lectins and a...
In the title compound, [Tm(C6H5Se)3(C4H8O)3], the Tm(III) atom lies on a threefold rotation axis and is coordinated by three phenyl-seleno-late ligands and three tetra-hydro-furan ligands leading to a distorted fac-octa-hedral coordination environment. The Tm-Se and Tm-O bond lengths are 2.7692 (17) and 2.345 (10) Å, respectively, and the bond angles are 91.32 (6)° for Se-Tm-Se, 92.6 (2) and 94...

interoperability of devices. Overview EtherNet/IPTM (EtherNet/Industrial Protocol) is an industrial automation networking protocol based on the IEEE 802.3 Ethernet standard that has dominated the world of IT networking for the past three decades. Despite Ethernet’s unparalleled success in a wide range of business applications, modifications for industrial applications are necessary because stan...
Land use classification and mapping mostly use remotely sensed data. During the past decades, several advanced classification methods such as neural network and support vector machine (SVM) have been developed. In the present study, Landsat TM images with 30m spatial resolution were used to classify land uses through two classification methods including support vector machine and neural network...
Tropomyosin (Tm) is a coiled-coil protein that binds to filamentous actin (F-actin) and regulates its interactions with actin-binding proteins like myosin by moving between three positions on F-actin (the blocked, closed, and open positions). To elucidate the molecular details of Tm flexibility in relation to its binding to F-actin, we conducted extensive molecular dynamics simulations for both...
