Modifications of the molluscan feeding apparatus have long been recognized as a crucial feature in molluscan diversification, related to the important process of gathering energy from the environment. An ecologically and evolutionarily significant dichotomy in molluscan feeding kinematics is whether radular teeth flex laterally (flexoglossate) or do not (stereoglossate). In this study, we use a...

A Local Load Sharing (LLS) model recently developed by Curtin and co-workers for the numerical simulation of tensile stress-strain behavior in fiber-reinforced composites is used to predict the tensile strength of metal matrix composites consisting of a Titanium matrix and unidirectionally aligned SiC fibers. This model is extended to include the effects of free boundary conditions and non-cons...

this study was carried out in the winter of the year 2007 in a dairy herd at the vicinity of tehran (eslamshahr). measurements were performed on 18 holstein cows during first-lactation. five holstein dairy cattle were randomly selected and clinically studied, too. length of the claw’s dorsal flexure was measured with a ruler and also the hooves trimmed in the toe vertically for measuring of the...

By Timothy Phillips Vaughan, MS. Washington State University May 2010 Chair: David I. McLean This research evaluated the structural performance of reinforced masonry shear walls conforming to requirements given in the 2008 MSJC Building Code Requirements for Masonry Structures under cyclic lateral loading. Seismic design provisions in the 2008 MSJC provide prescriptive requirements for three di...

A 66-year-old female patient was admitted to a general surgery polyclinic with abdominal pain. She was treated for pulmonary tuberculosis (PT) 28 years ago. On performing a physical examination, right upper quadrant tenderness was detected. Laboratory parameters were unremarkable. Abdominal ultrasonography (USG) findings were compatible with cholelithiasis and wall thickening of a hepatic flexu...
