gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Egg hatching of winter-collected Ochlerotatus albifasciatus was studied for six months. Batches of eggs were divided into two groups, one of them was stored in the laboratory at 23 degrees C and 12:12 photoperiod, and the other in the field under dead leaves. Every month, from July to December, eggs from the two groups were flooded under both laboratory and field conditions. Unhatched eggs were...
The major bottleneck of today's atomistic molecular dynamics (MD) simulations is that because of the enormous computational effort involved, only processes at nanoseconds to microseconds time scales or faster can be studied directly. Unfortunately, apart from a few exceptions, relevant processes, such as chemical reactions or many large scale conformational transitions in proteins, occur at slo...
Introduction While most people who are involved in disasters recover with the support of their families, friends and colleagues, the effects on some people’s health, relationships and welfare can be extensive and sustained. Flooding can pose substantial social and mental health problems that may continue over extended periods of time. Flooding can challenge the psychosocial resilience of the ha...
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...
Flooding in Mobile Ad hoc Networks (MANET) is an important communication primitive. It serves as a building block for higher layer protocols like content distribution, route discovery in routing protocols as well as used by services like Address Resolution Protocol (ARP) and Dynamic Host Configuration Protocol (DHCP). The nodes in real MANETs are not uniformly distributed. There are always dens...
Background/introduction Unilateral lung flooding replaces air with saline in lung parenchyma. It has been shown, that in flooded condition ultrasound guidance and HIFU ablation of central lung cancer tissue is feasible. The flooding process generates a saline-lung compound which is different than known parenchymal tissue. Complete understanding of the flooding process is essential for its imple...
