Abstract The processing of wood as a renewable and sustainable material is steadily gaining in importance. However, sawing processes sawmills are characterized by high electrical energy consumption. Improving the geometry saw teeth an option to make more efficient sustainable. Since industrial rather inflexible, development new tooth geometries takes place smaller experimental setups. inhomogen...

The effects of the Engineered Micro-Geometry (EMG) carbide teeth circular saws on their wear rate and resulting sawing variation for 2-time intervals were studied. objective was to improve resistance used during primary transformation wood. tests carried out under industrial production conditions with two series saws; 1- up-sharp tips, 2- cutting edges honed adopt a waterfall geometry. duration...

BACKGROUND Rho-associated kinase (ROCK), an effector of small GTPase Rho, regulates vascular tone via a calcium sensitization mechanism and plays a key role in the pathogenesis of hypertension. However, its role in vascular growth remains unclear. METHODS AND RESULTS Y-27632, a specific ROCK inhibitor, and the overexpression of dominant-negative ROCK suppressed the mitogen-induced DNA synthes...

In the forest products manufacturing industry, recent price increases in the cost of high-quality lumber together with the reduced availability of this resource have forced manufacturers to utilize lower grade hardwood lumber in their manufacturing operations. This use of low quality lumber means that the labor involved in converting this lumber to usable parts is also increased because it take...

In soft-wood sawmills in the western U.S., the green lumber end-product is the result of several distinct sawing operations: an initial breakdown of large diameter logs by a headrig yields boards that are subsequently resawn one or more times by secondary saws of various types. Vibration of the saws contributes to irregularities in thickness of the final green lumber. Misalignment of the saws p...

RhoA/Rho kinases (ROCK) play a critical role in vascular smooth muscle cell (VSMC) actin cytoskeleton organization, differentiation, and function and are implicated in the pathogenesis of cardiovascular disease. We have previously determined that an important step in the regulation of calcification is fetuin-A endocytosis, a process that is dependent on changes in the cytoskeleton, which, in tu...

Nucleophosmin (NPM)/B23 has been implicated in the regulation of centrosome duplication. NPM/B23 localizes between two centrioles in the unduplicated centrosome. Upon phosphorylation on Thr(199) by cyclin-dependent kinase 2 (CDK2)/cyclin E, the majority of centrosomal NPM/B23 dissociates from centrosomes, but some NPM/B23 phosphorylated on Thr(199) remains at centrosomes. It has been shown that...

For spruce (Picea abies (L.) Karst.), as with most other species, the value of a log is to great extent determined by its defects. That is the reason why sawyers, aiming at the optimal utilization of a log, were naturally interested in defects, their number, position and shape. X-ray computer tomography (CT) scanning is able to detect internal density variations related to defects. In order to ...
