This paper presents the development of an Intelligent Cavity Layout Design System (ICLDS) for multiple cavity injection moulds. The system is intended to assist mould designers in cavity layout design at concept design stage. The complexities and principles of cavity layout design as well as various dependencies in injection mould design are introduced. The knowledge in cavity layout design is ...

The N- and C-terminal six-helix bundles of lactose permease (LacY) form a large internal cavity open on the cytoplasmic side and closed on the periplasmic side with a single sugar-binding site at the apex of the cavity near the middle of the molecule. During sugar/H(+) symport, an outward-facing cavity is thought to open with closing of the inward-facing cavity so that the sugar-binding site is...

Habitual, moderate exercise is associated with improved health, including reductions in illness. These benefits may stem, in part, from immune function improvements. We have previously reported that daily wheel running increases serum and peritoneal natural IgM (nIgM) in pathogen-free Sprague-Dawely rats. B-1 cells, which primarily reside in the peritoneal cavity, produce nIgM in the absence of...

We report three-dimensional (3D) imaging of microcirculation within human cavity tissues in vivo using a high-speed swept-source optical coherence tomography (SS-OCT) at 1300 nm with a modified probe interface. Volumetric structural OCT images of the inner tissues of oral and nasal cavities are acquired with a field of view of 2 mm × 2 mm. Two types of disposable and detachable probe attachment...

Laparoscopic percutaneous extraperitoneal closure of inguinal hernia with variable devices as an effective technique in minimal-access surgery for pediatric inguinal hernias in children was investigated in the present study. A Veress needle was inserted into the abdomen. Trocars, laparoscope and needle holder were placed through the umbilical incision. Under laparoscopic monitoring, a round nee...

Cholesterol oxidase is a monomeric flavoenzyme that catalyzes the oxidation and isomerization of cholesterol to cholest-4-en-3-one. Two forms of the enzyme are known, one containing the cofactor non-covalently bound to the protein and one in which the cofactor is covalently linked to a histidine residue. The x-ray structure of the enzyme from Brevibacterium sterolicum containing covalently boun...

lorestan and other part of iran are one of the important endemic focuses for the major zoonotic parasitic diseases like cystic hydatid disease where several species of intermediate host are commonly infected with echinococcus granulosus . meat inspection records in a slaughtered house were used to determine the prevalence of hydatidosis in sheep, cattle, and goats in lorestan province (aleshtar...
