This study examined the test-retest reliability, inter-rater reliability, convergent validity and discriminant validity of the Fine Motor Scale of the Peabody Developmental Motor Scales-second edition (PDMS-FM-2). Participants included two groups of 18 children between the ages of 4 and 5 years with and without mild fine motor problems. The PDMS-FM-2 was administered twice to 12 children and ra...

Polydimethylsiloxane (PDMS) is widely used in a number of industrial processes and consumer products that result in down-the-drain disposal. The log p value for the PDMS used in the present study was 10, and the vapor pressure and water solubility values were below detection limits. These physicochemical characteristics and a measured degradation rate of 3% after six months in moist soils sugge...

Silica or glass particles are introduced in a poly(dimethylsiloxane) (PDMS) matrix for various applications. A particular feature of these systems is that PDMS adsorbs on the surface of the dispersed particles, thus rendering them more hydrophobic with time. The mechanism of this process of in situ hydrophobization is still poorly understood. The major aims of the present study are (1) to quant...

BACKGROUND AND PURPOSE The psychometric properties of the Peabody Developmental Motor Scales-Second Edition (PDMS-2), a revised motor test to assess both gross motor and fine motor composites in children with cerebral palsy (CP), are largely unknown. The purpose of this study was to examine the test-retest reliability and the responsiveness of the PDMS-2 for children with CP. SUBJECTS A sampl...

Inside spaces of emulsion droplets can be used as mini-reactors for material synthesis. The novel application of sol-gel derived silicone oil droplets as mini-reactors was examined for the case of polymerization of styrene (St) and comonomers with the oil-soluble initiator 2,2'-azobis(2,4-dimethylvaleronitrile). Polydimethylsiloxane (PDMS) droplets prepared from dimethylsiloxane were used as th...

Polydimethylsiloxane (PDMS) is the elastomer of choice to create a variety of microfluidic devices by soft lithography techniques (e.g., [1], [2], [3], [4]). Accurate and reliable design, manufacture, and operation of microfluidic devices made from PDMS, require a detailed characterization of the deformation and failure behavior of the material. This paper discusses progress in a recently-initi...

In this work, graphene/Ag (GA/Ag) composite aerogels with the micro rough porous structure and conductive property polydimethylsiloxane(PDMS) low surface energy were used to prepare super-hydrophobic cotton fabric (GA/Ag/PDMS@cotton) was successfully prepared. The morphologies, chemical composition, wettability, microwave absorption of GA/Ag/PDMS@cotton characterized. It shown that GA/Ag PDMS c...

Abstract The influence of radiation-moisture aging on the thermodynamic and interface properties nano-silica/silicone rubber (PDMS) composites was investigated using molecular dynamics simulation. deterioration polymer matrix incorporated into PDMS-silica models based hydrolysis products dominant role cross-linking over chain scission. results indicate that long-chain structure with higher weig...
