Two hundred ninety-six gestating sows were used to determine the physical dimensions of sows in commercial settings. Sows were examined from five farms within a single production model that included identical feed formulation, management practices, herd health, and similar, but not identical, genotypes. Sows were individually weighed, backfat thickness was determined by ultrasound, and body dim...

A path to a new high performance regime has been discovered in tokamaks that could improve the attractiveness of a fusion reactor. Experiments on DIII-D using a quiescent H-mode edge have navigated a valley of improved edge peeling-ballooning stability that opens up with strong plasma shaping at high density, leading to a doubling of the edge pressure over the standard H mode with edge localize...

Open sinus lift surgery is a form of pre-prosthetic surgery for increasing the quality and quantity of bone in the posterior region of the maxilla. Pre-operative assessment of the maxillary sinus is essential for the success of this surgery. PubMed search was carried out in English language literature for open sinus lift surgery and cone-beam computed tomography (CBCT). The results focused on a...

The geometric shape of flat storage systems for grain influences economic feasibility. Total cost per unit volume first decreases and then increases as vertical wall height increases. For a given wall height and length, cost per unit volume decreases as facility width approaches length. INTRODUCTION The term "flat storage" generally refers to rectangular-shaped structures with relatively low he...

Abstract The current study used remote sensing, GIS, and seismic data to determine the geological morphometric parameters of Wadi Beda Basin area, which is located in northwestern part Gulf Suez Province. geomorphic related with development neotectonics are deduced using Shuttle Radar Topography Mission (SRTM), DEM-derived catchments, drainage networks research area. most important applied area...

PURPOSE This article describes a technique and reports on the early healing for localized sinus augmentation using a crestal approach in combination with an autologous leukocyte- and platelet-rich fibrin (PRF) concentrate. MATERIALS From November 2008 to January 2010, 138 implants were placed in 110 patients using osteotome-mediated sinus floor elevation (OMSFE) with PRF. RESULTS The mean r...

The valley oak (Quercus lobata Neé) is among the largest and longest lived of the North American oaks, attaining trunk diameters up to 4 m, heights of 12 to 25 m, and ages of 300 years or more. Unique to California, this oak is also one of California’s most familiar and evocative icons. Where they occur, large valley oaks are focal visual and ecological elements of both developed and rural land...
