The study on the adsorption and micropore filling of water vapor in coal is significant for predicting coalbed methane content seams. primary purpose this to explain effects pore structure its surface chemistry monolayer adsorption, filling, diffusion coefficient. First, X-ray diffraction (XRD) mercury intrusion porosimetry (MIP) analyzed inorganic mineral components two kinds samples fissures ...

For the first time, relationship between equilibrium moisture content and water activity is reported for desorption process in pork liver. that purpose, a standardized conductivity hygrometer was used at four different temperatures (0, 10, 30 50 °C) over wide range of (0.999–0.103). Five models frequently found literature (GAB, Oswin, Henderson, Hasley Ratti) were considered purposes describing...

Der LEGO Roboter Mindstorms EV3 sollte in die Informatik Veranstaltung im Studiengang Mechatronik integriert werden, um den Studierenden einen praktischen Einblick zu geben und die Motivation zu erhöhen. Gelehrt werden soll dabei die Programmiersprache C mit der Entwicklungsplattform Eclipse. Da es bisher keine Möglichkeit gab, den Roboter in ANSI-C zu programmieren, wurde mit der Entwicklung e...

Can the sorption mechanism be proven by fitting an isotherm model to experiment? Such a question arises because (i) multiple models, with different assumptions on mechanisms, often fit experimental equally well, (ii) some models [such as Brunauer–Emmett–Teller (BET) and Guggenheim–Anderson–de Boer (GAB)] isotherms that do not satisfy underlying of model, (iii) (such Oswin Peleg) are empirical e...

The important, while mostly underestimated, step in the process of short-term load forecasting–STLF is selection similar days. Similar days are identified based on numerous factors, such as weather, time, electricity prices, geographical conditions and consumers’ types. However, those factors influence differently within different circumstances conditions. To investigate optimise process, a new...

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...
