In this study, moisture content, free fatty acids, peroxide, iodine value, unsaponifiable matter, saponification value, fatty acid composition and tocopherol contents of wheat germ oil obtained by SC-CO2 extraction and cold press technology were investigated. Moisture, free fatty acid (FFA), peroxide value, iodine value, unsaponifiable matter and saponification value of cold pres...

Background and Aim: One of the problems of all ceramic restorations is their risk of fracture due to occlusal loads. The aim of the present study was to compare the effect of two marginal designs (shoulder and chamfer) on the fracture resistance of IPS-emax all ceramic restorations. Materials and Methods: One extracted maxillary first premolar received chamfer 50' marginal preparation (0.8 m...

in this research the utilization of acacia wood (acacia salicina) in medium density fiber board production was investigated. sample boards were made from acacia fibers at two resin contents (10, 12%), two press temperatures (175, 185 ˚c) and three press times(3, 4, 5 min). the results were analyzed based on a complete randomized design (crd) under a factorial experiment. results revealed that i...

bone-patellar tendon auto graft is probably the most widely used graft for acl reconstruction. several methods for graft fixation have been described. to avoid intra-articular hardware we adopt biological fixation with a femoral trapezoidal press-fit fixation. a prospective study was performed on 30 consecutive active people who underwent acl reconstruction with this technique by two surgeons b...

newspaper is not merely a tool for showing sufferings, but  considered as a tool for expressing thought that receives its effect from power of words. satirical literature has taken up a great area of the newspaper to express different issues. expressing sufferings in a humorous way makes the audience or reader laugh and is useful as a sharp tool for warning about defects. egyptian journalist , ...

studies had shown that oxygenated compounds are important in food products. it seems that extraction methods had a profound influence on this factor. the goal of the present study is to investigate on flavor components of murcott mandarin obtained using cold-press and hydro distillation. in the last week of january 2012, at least 50 mature fruit were collected from many parts of the same trees....

particle size, board density and adhesive content are the most important factors, influencing on physical and mechanical properties of particleboard. in this study the effects of density, adhesive content and particle size on withdrawal strength of particleboard made from populus (populus alba) particles have been studied. three levels of density including 0.65, 0.7, and 0.75 g/cm3, three level...

In 1952–1954 Higuchi and his group have instrumented upper and lower compression, ejection, and punch displacement on an eccentric tablet press, and pioneered the modern study of compaction process. This work was followed by Nelson who was the member of the original group. In 1966, a U.S. patent was granted to Knoechel and coworkers for force measurement on a tablet press. This patent was follo...

The purpose of this study was to examine the influence of two different bar diameters on neuromuscular activation and strength. The bar diameters used reflected a standard Olympic bar (28 mm (1.1 inch); THIN) and a larger fat bar (51 mm [2 inch]; THICK). Eighteen healthy men (age 25.06 1 years) were assessed for their maximal voluntary contraction (MVC) during a unilateral isometric bench press...
