My research program focuses on identifying and quantifying sediment erosion, transport, and deposition processes on the continental shelf through state of the art observational techniques in both fine grained and sandy environments. In sandy environments, my goal is to understand the detailed interactions and feedbacks between hydrodynamics, bedforms, and the resulting sand transport. In fine-g...

این تحقیق جهت بررسی اولتراسونوگرافی داپلر رنگی، طیفی و اولتراسونوگرافی داپلر رنگی سه بعدی قلب جنین در یک سوم انتهایی آبستنی در 7 قلاده سگ انجام شده است. این سگ ها همگی سالم با میانگین وزنی و انحراف معیار 89/1±9/14 کیلوگرم از نژاد مخلوط بودند و آبستنی آنها بیشتر از 40 روز بود. آبستنی توسط اولتراسونوگرافی دوبعدی و تخمین سن جنین با روش اندازه گیری bi-parietal diameter(bpd) تأیید شدند.سگ های انتخاب...

As an alternative to the construction of new infrastructure, repurposing existing natural gas pipelines for hydrogen transportation has been identified as a low-cost strategy substituting with in wake energy transition. In line that, 342 km, 36″ pipeline was used this study simulate some technical implications delivering same amount different blends and hydrogen, 100% hydrogen. Preliminary find...

Abstract. The glacial landscape of the Alps has fascinated generations explorers, artists, mountaineers, and scientists with its diversity, including erosional features all scales from high-mountain cirques to steep valleys large overdeepened basins. Using previous glacier modelling results empirical inferences bedrock erosion under modern glaciers, we compute a distribution potential in over l...

Reftable reconstruction of former topography in deformed regions is commonly difficult, due to degradation of former erosional and depositional surfaces. In contrast o most modem landscapes, however, ancient localities can sometimes provide clearer insights on subsurface geometries of deposition, deformation, and erosion and on theft variations through time. In some exceptional circumstances, a...

Mass-transport complexes (MTCs) form a significant component of the stratigraphic record in ancient and modern deep-water basins worldwide. One such basin, the deep-marine margin of eastern offshore Trinidad, situated along the obliquely converging boundary of the Caribbean and South American plates and proximal to the mouth of the Orinoco River, is characterized by catastrophic shelfmargin pro...
