Abstract Although direct measurements of the fuel injection pressure and travel injector needle in conjunction with valve train mechanism timing can provide complete diagnostic information about technical conditions systems, this requires installation sensors other equipment directly into which is possible within research laboratories but generally forbidden during operation ship. Malfunctions ...

Clear images of myosin filaments have been seen in shadowed freeze-fracture replicas of single fibers of relaxed frog semitendinosus muscles rapidly frozen using a dual propane jet freezing device. These images have been analyzed by optical diffraction and computer averaging and have been modelled to reveal details of the myosin head configuration on the right-handed, three-stranded helix of cr...

A frequency-response function–based parameter-estimation method was used for finite-element (FE) model calibration of a fullscale bridge using measured dynamic test data. Dynamic tests were performed on the bridge to obtain measured frequency-response functions. Data quality was ensured by comparing measured data with the FE model and removing erroneous data. A coherence data selector was devel...

OBJECT The sublime bridge is a potential site of entrapment of the median nerve in the forearm. To the authors' knowledge, this structure and its relationship to the median nerve have not been studied. The aim of the present study was to quantitate this structure and elucidate its relationship to the median nerve. METHODS Sixty adult cadaveric forearms underwent dissection of the sublime brid...

Phosphorylation of myosin regulatory light chain (RLC) N-terminal extension (NTE) activates myosin in thick filaments. RLC phosphorylation plays a primary regulatory role in smooth muscles and a secondary (modulatory) role in striated muscles, which is regulated by Ca(2+)via TnC/TM on the thin filament. Tarantula striated muscle exhibits both regulatory systems: one switches on/off contraction ...

The importance of smooth mould filling in the foundry casting process has been recognized for a long time. More uniform the filling process is, the better the quality of the casting of the products produced. Successful computer simulations can help to reduce the number of trials and cut down the lead time in the design of new casting products by better understanding the complex mechanisms and i...
