Homozygosity disequilibrium (HD), a nonrandom sizable run of homozygosity in the genome, may be related to the evolution of populations and may also confer susceptibility to disease. No studies have investigated HD using whole genome sequencing (WGS) analysis. In this study, we used an enhanced version of Loss-Of-Heterozygosity Analysis Suite (LOHAS) software to investigate HD through analysis ...
1 Agricultural Institute of Slovenia, Hacquetova ulica 17, 1000 Ljubljana, Slovenia, e-mail: [email protected] 2 Same address as 1, e-mail: [email protected] ABSTRACT Breeding programs require control of the level (F) and rate (ΔF) of inbreeding in order to avoid inbreeding depression. Increasing availability of genomic information has enabled a more accurate estimation of F and ΔF. This st...
The RoHS and WEEE European Directive, recently introduced, [1,2], represent focal points for the environmental regulation in the field of electronics industry. While removal of some material of concern has been relatively straightforward, the reduction or quite elimination of Lead (Pb) has caused significant disruption to the electronics manufacturing supply chain [3]. This materials and tech...
Solder paste is the main soldering material used to form strong solder joints between printed circuit boards (PCB) and surface mount devices in the surface mount assembly (SMA). On average 60% of endof-line soldering defects can be attributed to inadequate performance of solder paste stencil printing. Recently, lead-free solder paste has been adopted by electronics manufacturers in compliance w...
Parkinson's disease (PD) occurs in both familial and sporadic forms, and both monogenic and complex genetic factors have been identified. Early onset PD (EOPD) is particularly associated with autosomal recessive (AR) mutations, and three genes, PARK2, PARK7 and PINK1, have been found to carry mutations leading to AR disease. Since mutations in these genes account for less than 10% of EOPD patie...
The availability of high-density panels of genetic polymorphisms has led to the discovery of extended regions of apparent autozygosity in the human genome. At the genotype level, these regions present as sizeable stretches, or 'runs', of homozygosity (ROH). Here, we investigated both the genomic and the geographic distribution of ROHs in a large European sample of individuals originating from 2...
The implementation of the Restriction Hazardous Substances (RoHS) European Union (EU) Directive in 2005 resulted introduction pure tin as an acceptable surface finish for printed circuit boards and component terminations. A drawback finishes is potential to form whiskers. Tin whiskers are a metallurgical phenomenon that associated with rich/pure materials has been topic intense industry interes...
OBJECTIVES Yin yang haplotypes differ at every SNP. A previous study provided striking examples of these haplotypes, but claimed that their distribution across the genome could be attributed to chance. When we studied regions of homozygosity (ROHs) we found haplotypes that tended to differ at several SNPs simultaneously but did not subject this to formal testing. Here, we formally assess whethe...
This paper describes a study for waste of electrical and electronic equipment (WEEE) to characterise the plastic composition different mixed fractions. Most samples studied are currently excluded from material recycling arise as side streams in state-of-the-art plastics plants. These contain brominated flame retardants (BFR) or other substances concern listed persistent organic pollutants RoHS ...
Language and emotion are two related systems in use, in that one system (emotions) impacts the performance of the other (language). Both of them share their functionality in communication. Since the nature of foreign language classrooms is ideally interactional, emotional intelligence (EI) gains importance. The aim of this study was to find out whether one's total emotional quotient and its com...
