—Once an abundant and conspicuous presence in wetlands across much of north-central North America, Trumpeter Swan ( Cygnus buccinator ) poplulations were decimated in the midto late 1800s by a combination of market hunting, subsistence hunting, and habitat loss. Since then, restoration has focused primarily on reintroduction efforts in which captive-reared birds are released and then monitored....
In the Netherlands, for coastal and inland water applications, wave modelling with SWAN has become a main ingredient. However, computational times are relatively high. Therefore we investigated the parallel efficiency of the current MPI and OpenMP versions of SWAN. The MPI version is not that efficient as the OpenMP version within a single node. Therefore, in this paper we propose a hybrid vers...

در این تحقیق، از مدل عددی SWAN برای مدل سازی امواج و بدست آوردن ارتفاع موج مشخصه در محدوده ی بندر امیرآباد دریای خزر استفاده شد. برای این کار، ابتدا یک مدل کلی جهت مدل سازی ارتفاع موج در کل محدوده ی دریای خزر ساخته شد. سپس از شرایط مرزی به دست آمده از مدل کلی، با استفاده از عمل آشیانه سازی مدل SWAN ، مدل سازی محلی با درشت نمایی بیشتر در منطقه‌ی بندر امیرآباد استفاده شد. مدل محلی ساخته شده در من...
Pseudomonas aeruginosa is a nearly ubiquitous human pathogen, and infections can be lethal to patients with impaired respiratory and immune systems. Prior studies have established that strong loss-of-function mutations in the egl-9 gene protect the nematode C. elegans from P. aeruginosa PAO1 fast killing. EGL-9 inhibits the HIF-1 transcription factor via two pathways. First, EGL-9 is the enzyme...
Inactivated influenza virus vaccine prepared from a non-pathogenic influenza virus strain A/duck/Hokkaido/Vac-1/2004 (H5N1) from the virus library conferred protective immunity to chickens against the challenge of antigenically drifted highly pathogenic avian influenza virus (HPAIV), A/whooper swan/Hokkaido/1/2008 (H5N1). The efficacy of the vaccine was comparable to that prepared from genetica...
„Pontosan a növekedéselmélet az, amelyről beszélni akarok: önmagáért, az eredményeiért, lyukakért, amelyeket még be kell tömni … .” – mondta Robert M. Solow 1987-ben, Nobel-díjas előadása elején, és ez motivációja ennek tanulmánynak is. A modern úttörőinek tekinthető Bob Trevor Swan alapvető tanulmányai 66 évvel ezelőtt, 1956-ban jelentek meg. növekedési irodalom azóta elképesztően bővült. Ez i...
