An amoniumvanadate plus sodium molybdate mixed modifier Graphite Furnace Atomic Absorption Spectrometric method has been developed for determination of traces of lead in drinking water. The concentration of lead in the sample is obtained by direct comparison to linear working graph prepared from aqueous standards in the modifier medium, The results indicate the better performance of the pro...

Surface hot-in place recycling of asphalt mixtures has been conducted on Finnish roads for several years. The procedure is performed either in full-lane('remix') or shorter widths ('rut-remix'). In a 2020-2021 project, different mixture types were subjected to both kinds recycling; reference mixtures, and modified with aramid fibres, FEP elastomer pellets, polymer, Storelastic rubber additive, ...

We propose a pair of population genetic models for a modifier-of-imprinting locus for which different genotypes imprint different proportions of an imprintable target locus in their gametes. The two models examine the situations in which imprinting is advantageous, and we discuss three cases for which the modifier is respectively partially dominant, dominant, or recessive. The models predict th...

We have examined the effects of mutations in the six allele-specific modifier genes su(Hw), e(we), su(f), su(s), su(wa), and su(pr) on the expression of 18 modifiable alleles, situated at 11 loci. Ten of the modifiable alleles are associated with insertions of the gypsy retrotransposon and the others include alleles associated with insertions of copia and 412. We tested or retested 90 of the 10...

Modifier gene models are used to explore the evolution of features of organisms, such as the genetic system, that are not directly involved in the determination of fitness. Recent work has shown that a general "reduction principle" holds in models of selectively neutral modifiers of recombination, mutation, and migration. Here we present a framework for models of modifier genes that shows these...

A double-stranded RNA (dsRNA)-specific modification activity from Xenopus oocytes and human cells dsRNA modifier) converts adenosine residues present in dsRNA to inosines. The function of the dsRNA modifier is unknown, although it has been suggested that it may be part of the cellular antiviral response. We investigated the relationship between the activity of the dsRNA modifier, viral infectio...

In this study, the recycled PET is used in bitumen modification by applying a different process order to eliminate phase separation problem. For purpose, modified bitumens are obtained adding triethanolamine (TEOA) chemical (wt. 2.5 %) and 2, 4, 6, 8, 10 pure bitumen. The properties of determined chemical, physical, rheological tests. According test results, reacts with PET, 6 % ratio critical ...
