The elimination of compounds such as lead (Pb) and cadmium (Cd) from electrical and electronic equipment as a result of the Restriction of Hazardous Substances (RoHS) annex of the European Union’s Waste from Electrical and Electronic Equipment (WEEE) Directive 2002/95/EC is rapidly approaching the deadline of July 1, 2006. While the RoHS annex to the WEEE directive specifically refers to restri...
The PVC (polyvinyl chloride) and the PP (polypropylene) resin pellet certified reference materials (CRMs, NMIJ CRM 8123-a and 8133-a) with respect to the RoHS (restriction of the use of hazardous substances in electrical and electronics equipment) directive were developed in the present study. Both the sample pretreatment and the measurement procedures for the determination of Cd, Cr, Hg and Pb...
Considering the implications of EU environmental laws such as REACH (registration, evaluation, authorization, and restriction of chemicals) and EuP (directive on eco-design of energy-using products) as well as RoHS (restrictions of the use of certain hazardous substances in electrical and electronic equipment) Directive, they have been acquired to advance GSCM (green supply chain management) mo...
While it is now widely accepted that most electronic assembly can be reliably effected with lead-free solders, a practicable alternative to the high-lead high-melting-point solders has not been available. That reality has been acknowledged by the interim exemption from the requirements of the EU RoHS Directive granted for solders with 85% or more of lead. With no direct replacement yet found by...
Genome-wide association studies (GWASs) help to understand the effects of single nucleotide polymorphisms (SNPs) on breast cancer (BC) progression and survival. We performed multiple analyses on data from a previously conducted GWAS for the influence of individual SNPs, runs of homozygosity (ROHs) and inbreeding on BC survival. (I.) The association of individual SNPs indicated no differences in...
Metal halide perovskites (MHPs) are promising candidate materials for next-generation optoelectronic device applications such as light-emitting diodes (LEDs), solar cells, and photodetectors. However, the toxicity poor stability issues of lead-based MHPs (LHPs) still challenging to fulfill a restriction hazardous substances directive (RoHS) industrial standards commercialization LHP devices. Th...
A power cable is the most important part in a power transmission system. The cables must be total quality dedicated and certified for development, manufacturing and installation, however are exposed to a corrosive environment. The purpose of this paper is to show that the fast neutron radiography with a transportable system is a solution to find defects in the cables and reduce the cost of insp...
