The tea oil camellia (Camellia oleifera Abel., Theaceae) is notable as an important source of edible oil (known as tea oil or camellia oil) obtained from its seeds in China. Today camellia oil with a high oleic acid content is coming more into the focus of interest since the fatty acid composition is more comparable to olive oil. The process of cold-pressed oil extraction of camellia seeds was int...Show More
We have recently fabricated tellurium-doped zinc selenide (ZnSe:Te) in a robust optical ceramic form, in the first synthesis of this remarkable material from a precursor powder, using powder consolidation techniques. We utilized two techniques in particular-hot uniaxial and hot isostatic pressing-in order to achieve the desired physical and chemical properties, and we are continuing our efforts to...Show More

The shielding effect of capsule was studied during the processes of Hot Isostatic Pressing (HIP) by numerical simulation and HIP experiment of aluminum alloy powder. In addition, the experimental equations about the shielding effect of capsule were established. The results show that the shielding effect of capsule depends on geometry size of capsule, wall thickness and yield strength. The reduced ...Show More
In order to improve superconducting property of Bi-2223 superconductor bulk, 5 mm in width, 22 mm in length and ca. 2 mm in thickness, silver (Ag) wires of 0.4 mm in diameter were composed in the bulk. The composite was made by stacking alternately Ag wires and the calcined powder. The pressed sample was sintered at 840/spl deg/C for 50 hours in air. After treatment with a cold isostatic press (CI...Show More
In the study, a novel design and fabrication method, which is simple and optimizes press moulding for CFRP based on CAD data was proposed and assessed. CFRP has come into widespread use for weight reduction of transportation equipment in recent years. However, in order to expand the range of their purpose, reduction of the production cost and increasing the molding cycle is necessary. The author f...Show More
Horizontal leg press is a basic weight training exercise to strengthen extensor muscles of knee joint. Considering the specific purpose of this training, it's performed with different techniques. One of the major debates about performing this task concerns foot placement on the foot-plate. In this study, in order to investigate the effect of foot placement on the muscle contraction of knee extenso...Show More
