In this position paper we explore the application of refactoring to product line architectures (PLAs). A PLA is a common architecture for a set of closely related products. As the set of products and their features changes, the PLA must evolve as well. A typical problem in managing such evolution is that the overall structure of the PLA slowly but surely degrades. This is caused by the fact tha...

AIM Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) has been suggested as an independent predictor of cardiovascular events in epidemiological studies. We sought to evaluate Lp-PLA(2) as a risk factor for future cardiovascular events in patients with acute coronary syndromes (ACS) and to elucidate the relationship between Lp-PLA(2) and other known risk markers in ACS patients and healthy ...

The effects of annealing on the mechanical properties of polymer blends of poly(lactic acid) (PLA) and poly(ε-caprolactone) (PCL) were investigated. The bending strength and modulus of PLA/PCL tend to increase due to crystallization of the PLA phase by annealing. The mode I fracture energy, J(in), of PLA/PCL decreases dramatically due to the suppression of the ductile deformation of the spheric...

Oligomer Coupling Agents in Phosphate Based Glass Fibre/PLA Composites P Haque, AJ Parsons, I Ahmed, DJ Irvine, GS Walker, CD Rudd (Univ of Nottingham) Polylactic acid oligomers as coupling agents have showed potentially higher interfacial shear strength in phosphate based glass fibre/ PLA composites. To influence bonding on the glass fibre surface, the short chain PLA with different end groups...

Polylactide (PLA)/wood flour composite foam were prepared through a batch foaming process. The effect of the chain extender on the crystallization behavior and dynamic rheological properties of the PLA/wood flour composites were investigated as well as the crystal structure and cell morphology of the composite foams. The incorporation of the chain extender enhanced the complex viscosity and sto...

In this research, we present a simple and cost effective soft lithographic process to fabricate PLA scaffolds for tissue engineering. In which, the negative photoresist JSR THB-120N was spun on a glass subtract followed by conventional UV lithographic processes to fabricate the master to cast the PDMS elastomeric mold. A thin poly(vinyl alcohol) (PVA) layer was used as a mode release such that ...

China’s military planners like to claim that in overall terms, the PLA is technologically inferior if compared with its potential adversaries. Such inferiority will continue in the foreseeable future, even though the People’s Liberation Army (PLA) has made some progress in modernizing its weaponry in recent years. On the other hand, the strategic principles of the PLA have undergone a major shi...

The poly(lactic acid)/ethylene methyl acrylate copolymer (PLA/EMA) blends were melt blended with by a twin-screw extruder. The phase morphologies, mechanical, and rheological properties of the PLA/EMA blends with three weight ratios were investigated. The results showed that the addition of EMA improves the toughness of PLA at the expense of the tensile strength to a certain degree. All the PLA...

With the high demand of the portable electronic products, Lowpower design of VLSI circuits & Power dissipation has been recognized as a challenging technology in the recent years. PLA (Programming logic array) is one of the important off shelf part in the industrial application. This paper describes the new design of PLA using power gating structure sleep transistor at circuit level implementat...
