Objectives Dental instruments may serve as a route of infection transmission. The necessity of dismantling of Friction-Style (FS) and SpringStyle (SS) mechanical torque limiting devices (MTLDs) prior to disinfection and sterilization is a matter of debate, aside fromthe fact that it is difcult and time-consuming. This study sought to assess the effect of dismantling of components on quality of ...
Effect of Heat Input on Microstructure and Mechanical Properties in Friction Stir Welding of HSLA-60
High-strength low alloy steels are a class of steels used in applications that require high strength and good weldability, including ship hulls, gas pipelines and oil industry. One way to build parts is fusion welding that create areas with a large grain size in the heat-affected zone and increased susceptibility to hydrogen cracking. One way to solve this problem is to use solid state friction...
Growing up in rural China under the imposed hardships of the cultural revolution, Yigong Shi did not have the luxury of toys. Instead Shi, now the dean of the School of Life Sciences at Tsinghua University in Beijing, made elaborate models out of clay he collected from the fields. “I would stay for hours to a make a ship or train model with small parts,” he recalls. Decades later, as a structur...
Managers of marine protected areas (MPAs) must often seek ways to allow for visitation while minimizing impacts to the resources they are intended to protect. Using shipboard observers, we quantified the "zone of disturbance" for Kittlitz's and marbled murrelets (Brachyramphus brevirostris and B. marmoratus) exposed to large cruise ships traveling through Glacier Bay National Park, one of the l...
دینامیک کشتی در امواج تابع فاکتورهای مختلفی از جمله سرعت کشتی، اندازه کشتی، زاویه برخورد موج و ارتفاع موج است. اگر حرکات کشتی در امواج بلند و شرایط نامساعد دریا زیاد شود نتایج نامطلوبی را به دنبال خواهد داشت. ایجاد پدیده هایی چون خیسی عرشه، کوبش کف، خروج پروانه از آب و شتاب های بالا نتایج منفی را برای سازه و خدمه و مسافر و بار در پی خواهد داشت. بنابراین رفتار مناسب و آرام کشتی در امواج دریا و ش...
Whereas in the first concept safe enclosure of the plant was envisaged, it was then decided in favor of a step-by-step complete dismantling due to its significant advantages. The entire decommissioning program for achieving green-field conditions is divided into 8 steps. Prior to the approval and granting of sectional licenses by the licensing authority, documents describing all the work to be ...
Abstract The traditional master–apprentice architecture of doctoral supervision is undoubtedly undergoing change. In the anglophone world, father's house with its almost exclusively male occupants was first established in late nineteenth and early twentieth centuries. It persisted, largely undisputed, until final decades century, when numbers bloomed throughout West more women (and others) took...
The partial pressure of carbon dioxide (PCO 2 ) and concentrations of the nutrients phosphate (P) and silicate (Si) in coastal surface waters within a 100 km]300 km area centered on Cape Blanco, Oregon, were mapped at high resolution during August 17}27, 1995. Alkalinity and the concentration of total CO 2 were determined on a subset of stored samples. Over the 9}183C range in sea-surface tempe...
