Effect of combined radio-frequency/vacuum-press drying on the strength properties of Japanese larch board

Aim - study of renal arteries denervation for the surgical treatment of primary arterial hypertension. Materials and methods. Radio-frequency ablation from the side of artery adventitia was carried out on preparations of the renal arteries. Results. The study determined comprehensible regimes of radio-frequency ablation, not resulting in a large degradation of the renal arteries strength properties, but providing reliable denervation of these arteries. Micro-photos of the renal artery wall after carrying out radio-frequency ablation were obtained. Conclusion. It is shown that the most comprehensible way of the renal arteries denervation is radio-frequency ablation from the side of artery adventitia.

Sem Study

Tension wood (TW) is an abnormal tissue of hardwood trees; although it has been isolated from most parts of the tree, it is frequently found on the upper side of branches and leaning stems. TW has been classically associated with geotropic alignment, but more recently it has been associated with fast growth. Paper made from TW is generally lower in strength properties. Consequently, the paper industries' growing dependence on fast growing, short- rotation trees will result in higher amounts of TW in the final product and a corresponding reduction in strength.Relatively few studies have dealt with the role of TW in the structure of paper. It was suggested that the lower strength properties of TW were due to a combination of factors, namely, its unique morphology, compression failures in the cell wall, and lower hemicellulose content. Central to the unique morphology of the TW fiber is the thick gelatinous layer (G-layer) composed almost entirely of pure cellulose.
