Climate and tourism are strong correlated. Urban areas have a relevance concerning not only to cultural tourism but also for recreation. The high discussed topic of global change is focused in the tourism climatology as well. We analyzed exemplarily the climate potential and its variation of Freiburg. The analysis is based on the simulations of the regional climate models REMO and CLM for the A...

We obtain exact analytic solution for the Green functions and survival probabilities of the reversible, geminate diffusion-influenced reaction A1B↔C1D in Laplace space, and in the time domain for various spatial dimensionalities. The asymptotic behavior ~in one and three dimensions! goes as t, like in the irreversible case, but approach to this limit may occur from either above or below. The im...

با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...

Background Micro-RNAs (miRNAs) are a class of small non-coding RNA molecules that function though post transcriptional regulation of gene expression by a process termed RNA interference (RNAi). RNAi–mediated targeting of viral RNAs is recognized as an antiviral defense mechanism. The epigenetic effect of miRNAs can either be direct, by interfering with virus genome, or indirect, through downreg...
