Poly(butylene terephthalate) (PBT) is difficult to foam due its unfavorable rheological behavior (low melt strength, no strain hardening). In particular, a high expansion and homogeneous cell morphology are achieve. This can be altered successfully by addition of multifunctional chain extenders. Chain extenders cause nondefined rarely understood changes in the polymer architecture usually descr...

Due to the sensitivity of spaceborne atomic clock many factors, variation law satellite bias (SCB) can be regarded as a grey system. The GM (1,1) model is most classical and basic system, which has been successfully applied in SCB prediction. Moreover, improved models have proposed widely used various forecasts since was generated. However, prediction performance these not obviously compared wi...

The axonal transport of the diverse group of polypeptides characteristic of slow component b (SCb), or Group IV, may be accomplished either by a bulk flow mechanism acting on each of the individual polypeptides or by their movement through the axoplasm as part of a physical complex or structural assembly. In order to determine if the SCb polypeptides travel as a cohesive unit (which would be co...

Molecular weight distribution (MWD) and short chain branching (SCBD) play a decisive role in the performance of linear low-density polyethylene (LLDPE). A model based on non-standard polymerization reaction scheme is developed for ethylene/α-olefin gas phase copolymerization fluidized bed reactor. Experimental MWD SCBD are simultaneously deconvoluted. The results obtained by this simultaneous d...

Stormwater runoff plumes, municipal wastewater plumes, and natural hydrocarbon seeps are important pollution hazards for the heavily populated Southern California Bight (SCB). Due to their small size, dynamic and episodic nature, these hazards are difficult to sample adequately using traditional in situ oceanographic methods. Complex coastal circulation and persistent cloud cover can further co...

The distribution of the proteins migrating with the slow components a (SCa) and b (SCb) of axonal transport were studied in cross-sections of axons with electron microscope autoradiography. Radiolabeled amino acids were injected into the hypoglossal nucleus of rabbits and after 15 d, the animals were killed. Hypoglossal nerves were processed either for SDS-polyacrylamide gel electrophoresis flu...

Studies were carried out on the comparative study of the production of Avicelase enzyme using sugarcane bagasse-SCB in two different statuses (i.e. treated and untreated SCB) by thermophilic Geobacillus stearothermophilus at 50oC. Only four thermophilic bacterial isolates were isolated and assayed for Avicelase production using UntSCB and TSCB. Only one isolate selected as most potent and ident...

This paper describes a novel VLSI CMOS implementation of a self-compacting bu er (SCB) for the dynamically allocated multi-queue (DAMQ) switch architecture. The SCB is a scheme that dynamically allocates data regions within the input bu er for each output channel. The proposed implementation provides a high-performance solution to bu ered communication switches that are required in interconnect...

Branching epithelial morphogenesis requires interactions between the surrounding mesenchyme and the epithelium, as well as interactions between basement membrane components and the epithelium. Embryonic submandibular gland was used to study the roles of two mesenchymal proteins, epimorphin and tenascin-C, as well as the epithelial protein laminin-1 and one of its integrin receptors on branching...

The chain-branching process leading to ignition in the high-temperature hydrogenoxygen mixing layer is studied by application of a novel WKB-like method when, as is typically the case, two branching radicals cannot be assumed to maintain steady state. It is shown that the initiation reactions, responsible for the early radical buildup, cease being important when the radical mass fractions reach...
