This paper attempts to allocate a segment of the Paleozoic Ocean situated in what is now Southeastern Europe (SEE) into regional geological and paleotectonic synthesis connecting sedimentary, metamorphic igneous records associated with ocean’s cycle. The Supragetic basement (external section Carpatho-Balkan arch) represents tectonically reworked vestige Neoproterozoic–Lower oceanic floor system...
The demarcation of Iraq-Iran border at Shalamcha crossing border using multiple geomatics techniques
The demarcation of international borders is an essential issue. Although this can manage between neighboring countries, sometimes disputes may lead to many wars and problems. However, be solved officially by negotiation the two sides; actual solution required determination exact borderline with pillars' positions. Consequently, a series positioning computations are required, followed field work...
چکیده توده های گرانیتوئیدی ازنا – الیگودرز در حدفاصل شمال الیگودرز تا شمال ازنا در بین سنگهای دگرگونی ناحیه ای درجه پایین تا متوسط به سن اواخر تریاس تا اوایل ژوراسیک و با طیف ترکیبی اسلیت، فیلیت و میکاشیست جایگزین گردیده اند. این توده های نفوذی در محدوه سنی حدود 160 تا 170 میلیون سال پیش تشکیل و جایگزین شده اند. براساس مطالعات صحرایی و میکروسکپی، آنها دارای ترکیب سنگشناسی متشکل از گرانودیوریت...
The DFT calculations at the B3LYP level with 6-311G** basis set were carried out in order to reveal whether tautomerization or decarboxylation is responsible for the instability of 2,2-di(pyridin-2-yl)acetic (DPA) and 1,8-diazafluorene-9-carboxylic (DAF) acids. The carboxyl protons in both compounds are involved in the intramolecular hydrogen bonds (the pyridine nitrogen atoms are the hydrogen ...
