SHOX gene mutations or haploinsufficiency cause a wide range of phenotypes such as Leri Weill dyschondrosteosis (LWD), Turner syndrome, and disproportionate short stature (DSS). However, this gene has also been found to be mutated in cases of idiopathic short stature (ISS) with a 3-15% frequency. In this study, the multiplex ligation-dependent probe amplification (MLPA) technique was employed t...
Cementing systems using ultra-lightweight hollow spheres can improve lightweight cement performance in deepwater operations and provide a viable alternative to conventional lightweight cement slurries. Efforts to expand the temperature limits of MWD and LWD tools have seen limited success. New approaches may be necessary if industry is to meet the demand for gas from deep reservoirs. Mixing fra...
BACKGROUND The joint project “LWD Online Maps” between the Avalanche Warning Center Tyrol (Innsbruck, Austria) and the University of Vienna, Department of Geography and Regional Research is now ongoing for several years. Its goal has been and still is to develop and maintain a complex and very powerful database driven online decision support system for cartographic visualization and analysis of...
Complementary infinite-impulse response (IIR) filter pairs can be synthesized to generate power-complementary, allpass complementary, or magnitude-complementary filter pairs (see, e.g., [1]). A very attractive alternative to generate a power-complementary low-pass/high-pass IIR filter pair is to use lattice wave digital (LWD) filters (parallel connections of two all-pass filters) [2]–[4]. Usual...
This investigation was undertaken to determine the relative effects of recommended land spraying while drilling (LWD) loading rate application for a source of water-based drilling waste material on selected soil properties and phytotoxicity. Drilling waste material was obtained from a well where a nitrate gypsum water based product was used to formulate the drilling fluid. The fluid and associa...
Mutations in the homeobox gene SHOX cause SHOX deficiency, a condition with clinical manifestations ranging from short stature without dysmorphic signs to severe mesomelic skeletal dysplasia. In rare cases, individuals with SHOX deficiency are asymptomatic. To elucidate the factors that modify disease severity/penetrance, we studied a three-generation family with SHOX deficiency. The variant p....
برای بهره بردن از خواص و ویژگی های الگوریتم ها، نیازمند پیاده سازی آن ها در عمل هستیم. در میان الگوریتم های مختلف، الگوریتم های دیجیتال از اهمیت فراوانی برخوردارند. این اهمیت بدلیل برتری های سیستم های دیجیتال نسبت به آنالوگ است. پیاده سازی الگوریتم های دیجیتال در عمل یکی از چالش های مهم فن آوری روز است. در این میان سخت افزارهایی مانند پردازنده های سیگنال دیجیتال ، fpga و ... دارای کاربردهای وسی...
Abstract Drilling deviated wells has become customary in recent times. This work condenses various highly and horizontal well log interpretation techniques supported by field examples. Compared to that vertical wells, is complex because the readings are affected not only host bed but also adjacent beds additional wellbore-related issues. However, understanding potential pitfalls combining infor...
The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL were the deployment of specialized tools and measurement systems for use on ODP Leg 204, which studied hydrate deposits on Hydrate Ridge, offshore Oregon. Earlier deployments of these tools on ODP Leg 201 (Peru Margin) were made to prepare the tools and measurement systems for extensive use on ODP Leg 204. Prior to under...
