Using nonequilibrium molecular dynamics simulation, we have studied the response of a C100 model polymer melt to a step change from equilibrium to a constant, high shear rate flow. The transient shear stress of the model polymer melt exhibits pronounced overshoot at the strain value predicted by the reptation model, in striking similarity to melts of longer, entangled polymer governed by reptat...

Introduction: Since the synthesis, isolation and characterization of fullerenes more than a decade ago, there has been considerable interest in ascertaining whether or not this new family of carbon (C) molecules occur naturally on the Earth or in the Cosmos (e.g. circumstellar shells, interstellar medium or ISM etc.) [1,2,3]. For example, it has been suggested that the fullerene molecule, C60, ...

We have observed a sample of eleven PNe using the PHT-C100 camera on ISO, obtaining maps at 60 and 100 m. The PHT-32 mapping mode was used, resulting in images of the PNe and nearby sky background. A preliminary reduction of the data has conrmed that the radial extent of the cool dust in general is similar to the optical nebula. Two of the PN in our sample have been clearly resolved at 60 and 1...

Using a cell line, C100, that overproduces 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase; EC 1.1.1.34) 100-fold, we have studied the synthesis and insertion of this protein into the endoplasmic reticulum. The enzyme is synthesized on membrane-bound polysomes. It is cotranslationally but not post-translationally inserted into dog pancreatic microsomes. This cotranslational i...

Hepatitis C virus (HCV)-RNA in the blood was measured by polymerase chain reaction (PCR) in 37 subjects from eight families in which 2 or more persons tested seropositive for antibodies against C100-3 or CP9. HCV-RNA was positive in 17 of 37 subjects. Two or more HCV-RNA-positive subjects were observed in six of the families. Intrafamilial HCV infection was studied by determining the HCV-RNA ty...

The “P32” Astronomical Observation Template (AOT) provided a means to map large areas of sky (up to 45×45 arcmin) in the far-infrared (FIR) at high redundancy and with sampling close to the Nyquist limit using the ISOPHOT C100 (3×3) and C200 (2×2) detector arrays on board the Infrared Space Observatory (ISO). However, the transient response behaviour of the Ga:Ge detectors, if uncorrected, can ...

Perancangan dilakukan menggunakan metode modifikasi yang merujuk baja sebagai objek modifikasi. Modifikas...

objective(s) the effect of berberis vulgaris aqueous extract in hepatocarcinogenic rats was studied to investigate the apoptotic and sodium, potassium elements properties. a loss of both intracellular potassium and sodiumoccurs when apoptotic cells shrink and prior to the loss of membraneintegrity. materials and methods forty-eight sprague dawley rats were randomly divided into 2 groups, normal...
