Combination of laboratory measurements res ults of various properties, i.e. porosity, density, permeability and mineral composition, was done to get additional factors useful in fluid flow description in the Miocene sandy-shaly formation. Special computer processing of nuclear magnetic resonance outcomes and mercury injection porosimetry results turned out to be useful in the estimation of the ...

The drive to improve the sensitivity of nuclear magnetic resonance (NMR) to smaller and smaller sample volumes has led to the development of a variety of techniques distinct from conventional inductive detection. In this chapter, we focus on the technique of force-detected NMR as one of the most successful in yielding sensitivity improvements. We review the rationale for the technique, its basi...

امروزه با توجه به افزایش تقاضا و کاهش منابع انرژی، ذخیره سازی انرژی امری ضروری به نظر می¬رسد و مواد تغییر فاز دهنده وسیله مناسبی برای این منظور بشمار می¬روند. نقطه ضعف این مواد پایین بودن هدایت حرارتی آنهاست و یکی از راههای برطرف کردن این عیب، افزودن نانوذرات به این مواد است. در این پژوهش اثر نانو ذرات بتا سیلیکون کاربید بر خواص حرارتی ماده تغییر فاز دهنده پلی اتیلن گلیکول مورد مطالعه قرار گرفت...

When it comes to structural biology, bigger really is better. Most biological processes are performed by enormous multicomponent complexes, such as the ribosome. To solve the structures of these monsters, biologists traditionally have used two different but complementary techniques, nuclear magnetic resonance (NMR) and X-ray crystallography. They have had considerable success using the latter t...

Thrusting implication in the crustal thickening history of eastern Tibet is highly debated. The ?250 km-long Muli thrust Yalong belt SE a major Miocene structure with pronounced topographic step (?2,000 m). Using thermo-kinematic modeling based on thermochronology data, we constrain geometry as being steep (>70°) at surface, agreement field observations, and flattening depth (?20 km) an intra-c...

Creeping faults are difficult to assess for seismic hazard because they may participate in rupture even though likely cannot nucleate large earthquakes. The creeping central section of the San Andreas fault California (USA) has not participated a historical earthquake; however, earthquake ruptures nucleating locked northern and southern sections propagate through section. We used biomarker ther...
