metal spinning as a kind of manufacturing process has capability to shape hollow components. in present work shear spinning process is used to formplates into conical shapes. moreover, the aim of this research is to demonstrate the impact of the process parameters (i.e. feeding rate and spindle speed) on wall thickness. this approachwas done by experimental and finite elements method. the resul...

Computer simulations are powerful tools frequently used today in many important applications, for example to build safer buildings, to crash-test an automobile before it is built, to stabilize the Pisa tower, to design artificial joints that are comfortable and durable, or to investigate what-if scenarios to avoid and best recover from natural or man-made disasters. The simulation codes have re...

Active beef heart aconitase contains a [4Fe-4S] cluster. One iron of the cluster, Fea, is labile and can be removed easily by oxidation in air to yield the [3Fe-4S]1+ cluster of inactive aconitase. We have previously shown that substrate binds to Fea. We have continued our Mössbauer studies by further investigating the active and inactive forms of the enzyme. When active aconitase, [4Fe-4S]2+, ...

Buckwheat is an important minor crop with pharmaceutical functions due to rutin enrichment in the seed. Seeds of common buckwheat cultivars (Fagopyrum esculentum, Fes) usually have much lower rutin content than tartary buckwheat (F. tartaricum, Ft). We previously found a wild species of common buckwheat (F. esculentum ssp. ancestrale, Fea), with seeds that are high in rutin, similar to Ft. In t...

An important concern in the study of fracture healing is the ability to assess mechanical integrity in response to candidate therapeutics in small-animal systems. In recent reports, it has been proposed that microCT image-derived densitometric parameters could be used as a surrogate for mechanical property assessment. Recently, we have proposed an inverse methodology that iteratively reconstruc...

This thesis presents the characterization of an integrated starter/generator (ISG) based on an interior permanent-magnet (IPM) synchronous machine. The ISG is designed to operate in a hybrid vehicle; mounted to a traditional gasoline engine and coupled directly to the crankshaft. An experimental comparison is made between the design and the working prototype including a detailed description of ...

Background 18F-fluoride Positron Emission Tomography (fluoride-PET) is a functional imaging technique that mainly detects the acceleration of bone metabolism. We previously demonstrated the usefulness of fluoride-PET in various stages of hip osteoarthritis. Interestingly, the uptake was recognized even in the case without marked radipgraphical findings. The significant uptake in fluoride-PET in...

MSC is announcing a new business offering based upon a breakthrough technology. MSC has developed a means by which design engineers or occasional CAE software users can reliably perform complex engineering analysis with the same resultant quality as do the dedicated analysis experts. This breakthrough technology captures the expert’s engineering knowledge and specific process solution methodolo...

PURPOSE This study aimed to evaluate the effect of the placement of wide-diameter implants on bone stress concentrations and marginal bone loss in the first molar region. Study hypotheses held that increasing implant diameter would decrease peri-implant bone stress levels, but that statistically significant reductions in clinical bone loss would either (1) not be observed for any implant diamet...

To achieve accurate and precise results of finite element analysis (FEA) of bones, it is important to represent the load/boundary conditions as identical as possible to the human body such as the bone properties, the type and force of the muscles, the contact force of the joints, and the location of the muscle attachment. In this study, the difference in the Von-Mises stress and the total defor...
