ni-hard4 white cast iron is excellent wear resistant material and has been widely used in wearaffected equipment operated under extreme conditions, such as in mineral processing, cement, copper and iron manufacturing. in this study the effect of titanium addition (1.2, 0.7 and 0.2 wt.%) to the ni-hard 4 cast iron with the nominal composition of si= 1.5%, mn=0.5%, c=3%, p=0.05%, s= 0.05%, mo= 0....

honing is a process for finishing surfaces to obtain smooth surface. this process is used for finalpolish of inner parts such as engines cylinders. optimizing this process has always been a bigchallenge for mass production of cylinder blocks of internal combustion engines. honing processhas some variable parameters, thus to get their optimum rates the automobile cylinders were tested.in this re...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

The manufacturing industry has at its disposal a number of processes for constructing objects, including gravity casting, injection molding, stereolithography, NC-machining, deformation, composition, and spray deposition. The survey by Bose and Toussaint [3, 5] gives an overview of geometric problems and algorithms arising in manufacturing processes. Castingis one of the manufacuring processes ...

OBJECTIVE US Food and Drug Administration (FDA) warnings recommend monitoring negative symptoms associated with the initiation of antidepressant medications as these symptoms may interfere with full recovery and pose safety concerns. There is currently no brief, reliable rating instrument for assessing treatment-emergent, negative symptoms. We evaluated the psychometric properties of 2 versions...

We have previously shown (Sunkara et al., 1989; Taylor et al., 1991) that 6-o-butanoyl castanospermine (BuCast) was a 30-50-fold better inhibitor of HIV syncytia formation than castanospermine (Cast). Radiolabeled Cast and BuCast were used to study the uptake and metabolism of these compounds in cultured cells and in mice. BuCast was preferentially taken up by cells compared to Cast. Approximat...

Drosophila larvae exhibit klinotaxis when placed in a gradient of temperature, chemicals, or light. The larva samples environmental stimuli by casting its head from side to side. By comparing the results of two consecutive samples, it decides the direction of movement, appearing as a turn proceeded by one or more head casts. Here by analyzing larval behavior in a light-spot-based phototaxis ass...

Myostatin (MSTN) is an inhibitor of skeletal muscle growth, and a mutation in the gene coding region leads to increased muscling. Calpastatin (CAST) is a specific inhibitor of the ubiquitous calcium-dependent proteases, µ-calpain and m-calpain, found in mammalian tissues. In this study, genomic DNA was extracted from Zandi sheep blood samples. Gel monitoring and spectrophotometer methods were u...

We report that neuronal overexpression of the endogenous inhibitor of calpains, calpastatin (CAST), in a mouse model of human Alzheimer's disease (AD) β-amyloidosis, the APP23 mouse, reduces β-amyloid (Aβ) pathology and Aβ levels when comparing aged, double transgenic (tg) APP23/CAST with APP23 mice. Concurrent with Aβ plaque deposition, aged APP23/CAST mice show a decrease in the steady-state ...

subluxation of the proximal interphalangeal joint (pipj or pastern joint) is an uncommon condition that occurs in the forelimb or hindlimb. thoroughbred racehorses rarely show dorsal pastern subluxation (thoroughbred ringbone) secondarily to an injury to the soft tissues supporting the fetlock. a 4-year-old thoroughbred mare was presented with signs of lameness, swelling of the dorsal aspect of...
