Banknotes are widely exchanged for goods and services worldwide. During its circulation, it can get contaminated by money counting machines, atmosphere, dust, soil, storage process or during usage. soiling level is considered the most predominant reason classifying notes as defective, so reduction should be first aim of developing more durable banknotes. Many countries begin to apply clean note...

The basic assumption in the traditional inventory model is that all outputs are perfect items. However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable d...

We present an analysis of the hot pixel population in ACS CCDs. The number of hot pixels increases due to on-orbit radiation damage. In order to heal the defects responsible for the hot pixels, the CCDs are heated once a month. We review the effectiveness of the anneal process.

Compensatory growth (CG) may be an adaptive mechanism that helps to restore an organisms' growth trajectory and adult size from deviations caused by early life resource limitation. Yet, few studies have investigated the genetic basis of CG potential and existence of genetically based population differentiation in CG potential. We studied population differentiation, genetic basis, and costs of C...

Two of the antigenic characters of erythrocytes, that in either identical or related forms differentiate four species of Streptopelia (chinensis, humilis, orientalis, and senegalensis) from a fifth (S. risoria) by interaction of the causative genes, are involved in the appearance in backcross hybrids of additional antigenic specificities to those of the parental species. The cells of backcross ...

"HIV controllers" (HICs) are rare individuals in whom HIV-1 plasma viral load remains undetectable without antiretroviral treatment. This spontaneous viral control in HICs is usually associated to strong functional HIV-specific CD8(+) T cell responses. Accordingly, we have recently shown that CD8(+) T cells from HICs strongly suppress ex vivo HIV-1 infection of autologous CD4(+) T cells, sugges...

Coronaviruses contain a very large RNA genome, which undergoes recombination at a very high frequency of nearly 25% for the entire genome. Recombination has been demonstrated to occur between viral genomes and between defective-interfering (DI) RNAs and viral RNA. It provides an evolutionary tool for both viral RNAs and DI RNA and may account for the diversity in the genomic structure of corona...

BACKGROUND AND AIM: Regarding the prevalence of molar incisor hypomineralization (MIH) among students and different populations and continuation of related problems, it seems necessary to assess the prevalence among students in Kerman, Iran. The aim of this study was to review the prevalence of MIH and its relation to the sex of 7-12-year-old students in Kerman during 2015-2016.METHODS: In this...
