Abstract. Longitudinal haemodynamic force (LF) acting on a bifurcated stent-graft has been estimated previously using a mathematical model which assumes steady flow of an invisid fluid. An experimental method was developed, using an instrumented stent-graft model, to measure LF under human physiological and pathological blood flow conditions. The physical stent-graft model, with main trunk diam...

Abstract This study aimed to (1) characterized sago palms with different trunk formation times; (2) studied the growth characteristics related diameter of trunk. research was conducted at Sago Cultivation Experimental Site located in Pengkajoang Village, West Malangke District, North LuwuRegency.Thegrowth characters were number leaves, diameter, leaf length,petiole length, tree height,rachis su...

Understanding the physiology of epicormic sprout initiation and growth is economically important for arboricultural management. In this experiment, factors influencing the initiation and growth of epicormic sprouts, including light exposure, temperature, trunk growth, date of green pruning, and tissue concentrations of non-structural carbohydrate, were investigated in Prunus persica. Field tria...

OBJECTIVE To determine the patterns and clinical importance of saphenofemoral junction (SFJ) reflux in patients with chronic venous disease (CVD) and a normal great saphenous vein (GSV) trunk. METHODS Fifteen hundred consecutive patients were examined using duplex ultrasound (DU) in three centres. Patients with reflux involving the SFJ and/or its tributaries only were included and its prevale...

ABSTRACT. A numerical method was used to analyse the interaction of L-band microwaves with pine (Pinus merkusii) trunk. This method approximated tree trunk as an infinite length of two layers of cylindrical dielectric media. These layers are xylem and heartwood. Horizontal polarisation (transverse magnetic mode) of the scattered wave was derived in order to determine the relationship between tr...

BACKGROUND AND AIMS Altitudinal timberlines are thought to move upward by global warming, a crucial topic in ecology. Tall tree species (the conifer Abies mariesii and the deciduous broad-leaved Betula ermanii) dominate the sub-alpine zone between 1600 and 2500 m a.s.l., the timberline, on Mount Norikura in central Japan. Dwarf pine Pinus pumila dominates above the timberline to near the summit...

As urban development increases in density, the space to grow trees becomes more constrained. In heavily developed areas, small stature can be planted reduce both above- and below-ground conflicts with infrastructure elements. However, even these species interfere pavement when placed extremely confining conditions. this study, we build on past work determine minimum planting widths of trees. Sp...
