OBJECTIVES Clinicians often base the implementation of therapies on the presence of postural instability in subjects with Parkinson's disease (PD). These decisions are frequently based on the pull test from the Unified Parkinson's Disease Rating Scale (UPDRS). We sought to determine whether combining the pull test, the one-leg stance test, the functional reach test, and UPDRS items 27-29 (arise...

Surface dressings are a sustainable maintenance alternative for pavements with surface distresses, due to the low amount of resources involved. This paper aims analyze viability using twelve different dressing solutions, including three binders (conventional and modified emulsions, soft 160/220 bitumen) covering diluted emulsion, treatment Portland cement concrete (PCC) pavements. Several test ...

Pullulan (PULL)/silver (Ag) nanoparticle composite nanospheres were prepared out of aqueous solutions using electrospray technique by controlling the concentration of PULL solution. Since pullulan is a water soluble and interesting natural polymer for many of its merits and good properties, it is one of the best materials for preparation of antibacterial material. Scanning electron microscopy (...

In this paper, we propose the design of low power level-converting retention flip-flop (RFF)using LSSR technique for Zigbee System-onchips (SoCs).The proposed retention flip-flop allows the voltage regulator which generates the core supply voltage (VDD, core) is turned off during the standby mode and thus reduces the standby power and dc current of the Zigbee SoCs. This method is the combinatio...

[1] A sensitivity analysis reveals that large uncertainty exists in estimates of solute retardation factor R made from sorption push-pull tests. A simplified push-pull data interpretation method for estimating instantaneous linear sorption in confined aquifers is developed. The new method is less restrictive in its application than the conventional method that uses an approximate analytical sol...

Six polymeric coatings viz. 3LPE, 3p/2p CAT, PU, VE, LE and HSS have been selected each type of coating has applied separately on SS316L pipe external surface. The test samples subjected to adhesion tests by the peel strength pull-off methods, before after Hot Water Immersion (HWI) for 100 days. After completing test, values are found about 10.9, 1.8, 0.35, 6.8 N/mm respectively, whereas 10.77,...

The JKR (Johnson–Kendall–Roberts) method is widely used to measure the work of adhesion between soft materials. In this article, the JKR theory is summarized and three-dimensionless parameters are proposed to design a proper JKR experiment. The study of adhesion between two commonly used soft elastomers PDMS (Sylgard 184) and Ecofl ex 0300 are obtained with the measured pull-in and pull-off for...
