Computer simulation of aquaporin4-dependent water transfer across the hematoencephalic barrier

Ion transfer across the water|trifluorotoluene interface

Hematoencephalic barrier. Ultrastructure and histophysiology of the endothelium capillary of the neuronal nuclei of the mesencephalon.

The ultrastructure of the dorsal periaqueductal nucleus capillaries of the mesencephalon in the cat was studied under the electron microscope in relation to the hematoencephalic barrier, and its four structural levels: 1. Endothelium; 2. Basal membrane; 3, Pericytes; and 4. Glial prolongations. An analysis was performed of what occurs in these four components (in a non-experimental histophysiol...

the impact of computer-assisted language learning on achievement motivation of high school students

چکیده انگیزه دلیل اصلی رفتارهای ما است. به نظر می رسد انگیزه جزء جدایی ناپذیر فرایند یادگیری باشد. ارزش ذاتی موفقیت تمایل به پیشرفت را در یادگیرنده ایجاد میکند. به عبارت ساده این تمایل انگیزه پیشرفت نامیده میشود. انگیزه پیشرفت را میتوان در احساس یادگیرنده هنگام چالش با درس های مدرسه، لذت انجام فعالیت درسی، یا حس کشف پاسخ مشاهده کرد.حتی ممکن است انگیزه پیشرفت را در تلاش یادگیرنده برای جلب تایید...

a comparative pragmatic analysis of the speech act of “disagreement” across english and persian

the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...

Phase diagram of water from computer simulation.

The phase diagram of water as obtained from computer simulations is presented for the first time for two of the most popular models of water, TIP4P and SPC/E. This Letter shows that the prediction of the phase diagram is an extremely stringent test for any water potential function, and that it may be useful in developing improved potentials. The TIP4P model provides a qualitatively correct desc...
