As known, most important, and the hard part of pattern recognition for rock particles, is image segmentation. Segmentation can be divided into two steps, one is segmentation based on gray levels (called image binarization, sometimes) in which a gray level image is processed and converted into a binary image. Another is segmentation based on rock particle shapes in a binary image, in which overl...

The selectivity of different Rho kinase (ROCK) inhibitors in the spontaneously tonic smooth muscle has not been investigated. We examined this issue using Y-27632 [(R)-(+)-trans-N-(4-pyridyl)-4-(1-aminoethyl)-cyclohexanecarbox anecarboxamide, 2HCl], H-1152 [(S)-(+)-(2-methyl-5-isoquinolinyl) sulfonylhomopiperazine, 2HCl], HA-1077 [(5 isoquinolinesulfonyl) homopiperazine, 2HCl], and ROCK inhibit...

The paper presents a new microplane constitutive model for the inelastic behavior of jointed rock masses that takes into account the mechanical behavior and geometric characteristics of cracks and joints. The basic idea is that the microplane modeling of rock masses under general triaxial loading, including compression, requires the isotropic rock matrix and the joints to be considered as two d...

Rho-associated coiled coil containing protein kinase (Rho-kinase or Rock) is a well-defined determinant of actin organization and dynamics in most animal cells characterized to date. One of the primary effectors of Rock is non-muscle myosin II. Activation of Rock results in increased contractility of myosin II and subsequent changes in actin architecture and cell morphology. The regulation of R...

This study investigated the effect of the Rho kinase inhibitor Y-27632 and fasudil on the development of human mesangial cell (HMC) inflammation and fibrosis induced by high glucose and to clarify the contribution of the Rho/ROCK signaling pathway in the pathogenesis of diabetic kidney disease (DKD). High glucose (30 mmol/l) induced the Rho/ROCK signaling pathway. Western blotting was used to d...

A diversity of Devonian-Carboniferous volcanic arcs and granitoid intrusions are exposed in the Gurvansaykhan arc terrane southern Mongolia. Several giant porphyry Cu-Au-Mo deposits associated with within these arcs. The Bronze Fox deposit located central part is an example a potentially economic affinity adakite-like (i.e. 428 Mt grading 0.26% to 0.30% Cu for up 2,437 Mlb copper 0.84 Moz gold)...

Original scientific paper Aiming at answering the questions of wear and failure of hob in the rock breaking process, the rock breaking process was simulated in different broken rock conditions by using finite element method. The relationship between normal force, lateral force, rolling force and time was obtained by rock breaking simulation analysis on the single edge disc cutter. The rock stre...

We describe the design of an acoustic emission (AE) measurement assembly for reliable acquisition of a multi-year timeseries in steep alpine rock-walls. The motivation for collection of these data is to enhance understanding of freezinginduced rock damage. Because measurements in natural rock slopes are challenging, this study investigates technical options suitable to capture AE signals from d...

UNLABELLED The traumatized primary teeth have a great clinical significance because it not only have consequences on itself but also on its succedaneous developing permanent teeth due to its close anatomical relationship. The extent of severity is adjudged by the type of trauma and the age of the child at the time of trauma. For instance, avulsion and intrusive injuries present with high percen...
