In this paper, the bending behavior of rectangular plates with stepped thickness resting on an elastic half-space foundation is investigated through analytic method. Combined theory thin and moderately thick plate, plate divided into upper lower plates, Fourier series used to obtain analytical solution deflection interaction force between foundation. The influence modulus theory, dimension also...
Little is known about the ground-dwelling arthropod diversity in tropical montane cloud forests (TMCF). Due to unique habitat conditions in TMCFs with continuously wet substrates and a waterlogged forest floor along with the innate biases of the pitfall trap, Berlese funnel and Winkler extractor are certain to make it difficult to choose the most appropriate method to sample the ground-dwelling...
The Winkler extraction is one of the two fundamental sampling techniques of the standardized "Ants of the Leaf Litter" protocol, which aims to allow qualitative and quantitative comparisons of ant (Hymenoptera: Formicidae) assemblages. To achieve this objective, it is essential that the standard 48-hour extraction provides a reliable picture of the assemblages under study. Here, we tested to wh...
چکیده: ازبین رفتن موادرایج استفاده شده درساخت شمع ها، یکی ازدلایل عمده استفاده موادکامپوزیتی درساخت شمع هادردهه های اخیرگردیده است. موادمرسوم برای ساخت، معایب عمده ای دارندکه هزینه نگهداری راافزایش وطول عمربهره برداری رابه خصوص درمحیط های خورنده کاهش می دهند. استفاده ازموادکامپوزیتی همچون پلیمرهای مسلح شده با الیاف(frp)، یک جایگزین بهتر برای موادمرسوم درساخت و سازرا برحسب مقاومت،وزن،دوام وهزین...
Over the last years, time-efficient approaches for the discovery of links between knowledge bases have been regarded as a key requirement towards implementing the idea of a Data Web. Thus, efficient and effective measures for comparing the labels of resources are central to facilitate the discovery of links between datasets on the Web of Data as well as their integration and fusion. We present ...
