Platinum is an active catalyst for a large number of (electro)chemical reactions in aqueous solution. The observed catalytic activities result from an interplay between the intrinsic adsorption properties of platinum surfaces and their interaction with the aqueous environment. Although water networks have been extensively studied on close-packed surfaces, little is known about high-coverage sol...

neighborhoods within the hierarchy of urban structure are one of the smallest socio-physical building blocks of cities. traditional neighborhoods of iranian historic cities benefited from strong social relations which were flourished over the years and were manifested in the neighborhoods centers. in the modern era, the new master plans and the complementary local plans have disintegrated these...

Thermodynamically stable secondary structures have been found for adjacent splice junctions of 17 introns from 10 eukaryotic and viral mRNA precursors. Complementary regions in these structures position the exons to be ligated in a favourable orientation for splicing. The possible role of these structures in a general splicing mechanism in described.

Many studies of human sequential pattern learning demonstrate that learners detect adjacent and non-adjacent dependencies in many kinds of sequences. However, it is often assumed that the computational mechanisms behind extracting these dependencies are the same. We replicate the seminal finding that adults are capable of learning dependencies between non-adjacent words (Gómez, 2002). When we e...

A considerable amount of energy is released in the form of shock wave from explosive charge detonation. Shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. The rest of the shock wave energy is transferred to rock mass as ground vibration. Ground vibration is conveyed to the adjacent structures by body and surface waves. Geological structures li...

Pseudocysts containing activated enzymes are a common complication of pancreatitis. Pseudocysts can rupture into adjacent structures including the peritoneal cavity, adjacent organs, and rarely vascular structures. While arterial pseudoaneurysms and venous thrombosis or occlusion are well known complications of acute and chronic pancreatitis, only 17 cases of pancreas-portal venous fistula have...

Schwannomas are tumors that are typically benign. They are derived from Schwann cells (glial cells of the peripheral nervous system that serve to separate and isolate nerve cells from adjacent structures). The most common type of schwannoma is a benign tumor of cranial nerve VIII and is referred to as an acoustic neuroma. When extradural, such tumors usually present as masses that can invade ad...

and smooth, measuring 12.9 x 11.6 x 9.9 cm, located on the left flank, in the mesenteric region, displacing adjacent structures, suggestive of mesenteric cyst (Figure 1A). Laparotomy revealed a cystic mass, with approximately 10 cm in diameter, thin-walled, smooth, yellowish, with tortuous vessels on the surface, without adherence to adjacent structures, located in mesojejuno about 50 cm from t...
