The study examined the effect of Frankia, macronutrients, micronutrients, mycorrhizal fungi, and plant-growth-promoting fluorescent Pseudomonas sp. on total biomass, nodule weight, and nitrogen fixation of red alder (Alnus rubra) and snowbrush (Ceanothus velutinus) under greenhouse conditions. The soil samples were collected from a 10-year-old clearcut on the H.J. Andrews Experimental Forest, O...

Based on the strength reduction method, laws of slope displacement and changing positions sliding surface during filling process are studied. The model multistage fill is established by finite element software PLAXIS. difference compared between with no reinforcement under same working condition. Sensitivity analysis carried out from two aspects which internal factors external factors. shows th...

STUDY DESIGN Radiographic review of healthy volunteers. PURPOSE To determine the ideal sitting positions by measuring changes in lumbar lordosis (LL) and pelvic parameters (PPs) in various positions. OVERVIEW OF LITERATURE Prolonged sitting is generally accepted as an important risk factor for low back pain (LBP). It is now recognized that spinopelvic alignment is important for maintaining ...

Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

Spontaneous fluctuation indices of cardiovagal baroreflex have been suggested to be inaccurate measures of baroreflex function during orthostatic stress compared with alternate open-loop methods (e.g. neck pressure/suction, modified Oxford method). We therefore tested the hypothesis that spontaneous fluctuation measurements accurately reflect local baroreflex gain (slope) at the operating point...

Solar radiation is a key factor influencing the photosynthesis and transpiration of trees. In mountainous regions, solar income exhibits strong spatial heterogeneity due to topographical variations structural complexity forest. However, how individual trees in different social positions varies with slope position remains unclear. this study, daily horizontal ground (Rh), (i.e., at locations on ...

in this century due to population growth, the use of river water has become more complicated. since most rivers pass across loose and erodible areas, they always act as the most important factor of transferring eroded materials from the solid crust of the earth.  vortex basins are among the solutions known for the high-speed separation of solids from liquids (filtration). one of the problems of...

Imaging of lung perfusion using contrast-enhanced dynamic magnetic resonance (MR) was performed in both the supine and prone positions in six volunteers. Regions of interest (ROIs) were chosen in the dependent and non-dependent portions of the right lung. The percentage increase in signal intensity (SI) and the mean slope were calculated. In the supine position, the dorsal ROI had a greater inc...

The impact of varying soil, landscape, and climate conditions on the off-site transport of pesticides must be determined to develop improved pesticide management practices. This study quantified the rate of S-metolachlor dissipation after fall and spring application in eroded and rehabilitated landforms in which topsoil was moved from the lower slope to the upper slope. Fall-applied metolachlor...

Slope stability analysis is one of the most important tools to determine both natural as well man-made slopes. The main objective this study compare safety factor Jure landslide before and after an earthquake occurrence using Geostudio QUAKE/W module. Three different positions water table (top, middle bottom debris) were considered for study. factors deterministic probabilistic case are determi...
