Background: Chronic treatment with fetal bovine serum (FBS) causes gradual vasoconstriction, vascular wall thickening, and contractility reduction in organ-cultured vascular tissues. We have previously demonstrated that Rho-associated kinase (ROCK) inhibitors prevent the functional alterations of small arteries in response to the FBS treatment. Here, we tested a further hypothesis that the chro...

Vascular remodeling in response to hemodynamic alterations is a physiological process that requires coordinated signaling between endothelial, inflammatory and vascular smooth muscle cells (VSMCs). Extensive experimental and clinical studies have indicated the critical role of the Ras homolog gene family, member A/Rho‑associated kinase (ROCK) signaling pathway in the pathogenesis of cardiovascu...

Unexpected differential tidal pressures occurred during construction of a 62 Ha reclamation area at Townsville Port. The reduction in flows through new rock wall structure was conjunction with installation geotextile membrane. Tidal began to displace the and cover rock. This paper discusses tide data collected various stages how it used for estimating progressive differentials. These estimates ...

Based on the field observations host rock of tourmaline nodules in the Dehgah and Sarsakhti area are acidic dikes (Aplite) and monzogranite respectively. In these areas, nodules composed of tourmaline, quartz, alkali-feldspar, but leuco minerals component in Dehgah nodule are less than Sarsakhti area. The negative anomaly of Eu, enrichment in the light REE (LREE), decrease of HREE, and  fractio...

The problem of low digging efficiency and mining imbalance due to outdated technology degree equipment intelligence has long existed in coal mine roadway excavation work. Lithology identification is the key roadheading equipment. Accurate lithology significantly affects automatic control roadheader cutting conditions. Completing process rock wall by a involved following steps: building tunnelin...

Estaj manganese deposit is located close to the Estaj village, 40 km southwest of Sabzevar, in Central Iran and Sabzevar subzone. Based on field evidences and microscopic studies, the rock units of the study area are pyroxene hornblende tracy Andesite, crystalin andesitic tuff, pyroxen hornblende andesite, pyroxen andesite- basalt, chert and limstone. These rock units belong to Late Cretaceous ...

Stylolite networks and their insoluble residues (IR) are among the major concerns and the fundamental controls on the mining and processing of sedimentary decorative stones, largely made from dolomitized limestones. They are mainly used, as natural rock blocks and polished slabs, to construct and decorate floors and walls of buildings and monuments. Representative quarries in Khur areas, east o...

A manned submersible was used in a fjord in southeastern Alaska to study the distributional patterns of the red king crab (Paralithodes camtschaticus) and the Tanner crab (Chionoecetes bairdi) in summer. The cove was divided into three zones: inner, middle, and outer. Six types of habitats, including sand-mud, rock, shell, debris, rock wall, and algae, were identified from video tapes. A relati...

Seasonal frozen loess tunnel stability is controlled by many factors. To study the effects of water content and freeze-thaw cycles of loess tunnel stability, taking loess in Shanxi Yangqu No. 1 tunnel face as the research object, to do different moisture stability studies on loess tunnel after repeated freeze-thaw cycles. The results show that: (1) by the comprehensive structure potential and s...
