Background: Induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. An incoherent noise field is supposed to suppress the bioeffects of regular RF electromagnetic fields. The purpose of this study was to investigate the effect of GSM mobile phone-induced radiofrequency (RF) on the induction of oxidative stress in SP2/0 cell line. Materials and Meth...

Amorphous SiO(2) membranes were prepared via a 2-step plasma-enhanced CVD (PECVD) technique at room temperature on porous TiO(2)/Al(2)O(3) substrates. SiO(2) membranes showed molecular sieving properties with a high separation factor for He/N(2) and He/H(2), and high thermal stability, indicating the successful preparation of high-performance membranes at low temperatures.

The use of carbon-fibre-reinforced polymers (CFRP) laminates in structural applications where high strength-to-weight and high stiffness-to-weight ratios are required is wellestablished. However, because of structural distortions induced by moisture absorption effects, polymer matrix composites are not yet definitely considered suitable candidate for ultra-high precision engineering application...

total igm, iga, and igm-rheumatoid factor (rf) and iga-rf were quantitated in the serum and synovial fluid of 35 seropositive and 8 seronegative rheumatoid arthritis (ra) patients, using a sensitive enzyme-linked immunosorbent assay (elisa). mononuclear cells isolated from peripheral blood and synovial fluid of three seropositive patients were also stimulated in vitro with phorbol myristate ace...

Abstract Unprotected copper conductors are prone to oxidation and corrosion, especially when in contact with salt water or at high temperature. In this study, we compared commercially available coating graphene oxide plasma-enhanced chemical vapor deposition (PECVD) coated wires terms of antioxidation anticorrosion protection. Samples were subjected aging tests a spray chamber. Thereafter, both...

Firsts results on particle detection using a novel silicon pixel detector are presented. The sensor consists of an array of 48 squar pixels with 380 lm pitch based on a n–i–p hydrogenated amorphous silicon (a-Si:H) film deposited on top of a VLSI chip. Th deposition was performed by VHF-PECVD, which enables high rate deposition up to 2 nm/s. Direct particle detection using bet particles from Ni...

Techniques for cost-efficient operation of SiNx:H systems with a capability for hydrogen passivation in a manufacturing environment are analyzed. We conclude that SiNx:H performance may be optimized by a variety of techniques, and that the cost and productivity of the deposition tool may be the determining factors in the industry’s decision for a particular technique. PECVD constitutes the curr...
