The high strain rate behavior of two cellular materials was investigated using a quasi-static loading stage and a Kolsky bar apparatus. The yield stress of these core materials under dynamic loading was found higher than in quasi-static loading. However, the plateau stress after yielding is not so sensitive to strain rate. For Aluminum foam materials, the deformation was more localized for quas...
lin apparatus ,·,hieh could produce known amounts of angular momenlum in a pipeline was verified by direct measurement of axial and tangential velocity profiles. By using the assumption that a vortimetcr, with vanes spanning only the rotational core, responded to an equivalent solid rotational core, an expression was develop ed relating the angular velocity to the angular momentum. Comparison ...
In the absence of a hepatitis C virus (HCV) culture system, the use of a Semliki Forest virus replicon expressing genes encoding HCV structural proteins that assemble into HCV-like particles provides an opportunity to study HCV morphogenesis. Using this system, we showed that the HCV core protein constitutes the budding apparatus of the virus and that its targeting to the endoplasmic reticulum ...
This review summarizes the research on physiological responses to flooding of trees in the seasonal black-water wetland of the Mapire River in Venezuela. Inter-annual variability was found during 8 years of sampling, in spite of which a general picture emerged of increased stomatal conductance (gs) and photosynthetic rate (PN) during the flooded period to values as high as or higher than in pla...
In this work, the Isfahan Miniature Neutron Source Reactor (MNSR ) has been simulated using the MCNP code, and reactivity worth of flooding the inner irradiation sites of this reactor in an accident has been calculated. Also, by inserting polyethylene capsules containing water inside the inner irradiation sites, reactivity changes of this reactor in same such accident have been measured, the re...
Flooding on 1 of the Solomon Islands precipitated a nationwide epidemic of diarrhea that spread to regions unaffected by flooding and caused >6,000 cases and 27 deaths. Rotavirus was identified in 38% of case-patients tested in the city with the most flooding. Outbreak potential related to weather reinforces the need for global rotavirus vaccination.
Previous work on citrus trees has shown that an interstock, grafted between the rootstock and scion combination, not only can improve tree growth, longevity, fruit production, and quality, but also can increase salinity tolerance. This research was designed to evaluate flooding responses of2-year-old 'Verna' lemon trees [Citrus limon (L.) Burm.; VL] either grafted on 'Sour' orange (C. aurantium...
مدیریت اتصال پروتکل tcp، مستعد یک حمله ی کلاسیک بنام syn-flooding می باشد. در این حمله، مبدا تعداد زیادی از سگمنت های syn را به کامپیوتر طعمه می فرستد ولی گام سوم از الگوریتم دست تکانی سه مرحله ای را کامل نمی کند. این امر سبب می شود که منابع اختصاص یافته برای برقراری ارتباط در سیستم تحت حمله به سرعت مصرف شده و از ادامه ی فعالیت باز ماند. در این رساله به منظور مقابله با این حمله، سیستم تحت حمله ...
BACKGROUND Extensive flooding occurred during the winter of 2013-14 in England. Previous studies have shown that flooding affects mental health. Using data from the 2013-14 Public Health England National Study of Flooding and Health, we compared the prevalence of symptoms of depression, anxiety, and post-traumatic stress disorder between participants displaced by flooding and those flooded, but...
