The separation of compounds possessing amino groups (peptides, proteins, polyamino compounds) by capillary zone electrophoresis suffers from the interaction (sticking) of these solutes with the capillary wall. This sticking can result in the absence or incomplete separation of compounds or even in their retention in the capillary. Polyamidoamine (PAMAM) dendrimers are a class of spherical polym...

Many hybrid zones contain a deficit of hybrid genotypes relative to expectations from tension zone models. This is often associated with separation of parental genotypes into distinct habitats (mosaicism), but sometimes parentals can be found co-occuring in the same local population (bimodality). In both cases, prezygotic isolation may play an important role in determining the genotypic composi...

Electrophoresis in microfluidic devices is becoming a useful analytical platform for a variety of biological assays. In this report, we present a method that allows for an increased sensitivity of detection of fluorescent molecules in microfluidic electrophoresis devices. This capability is provided by the implementation of a particular buffer system that is designed to initially function in an...

Due to its excellent effect of surface subsidence reduction, the overburden-separation grouting (OSG) technology has been widely applied green mining. However, OSG changes mine pressure, and resultant gas emission in stope remains unclear. Therefore, with 22301 working face Tunlan Coal Mine as an example, overburden deformation stress distribution absence presence were studied through numerical...

At airports with closely-spaced parallel runways, the inability to conduct simultaneous approaches in all weather conditions is a cause of significant delay. One concept for reducing delay is paired approaches, where two airc raft on closely spaced approaches are ‘paired’, and the ‘trail’ aircraft stays within a safe zone relative to the ‘lead’. This positioning guarantees that neither aircraft...

this field study was conducted on 60 women who working in related centers of universities of medical sciences in tehran. data gathering tool was maternal separation anxiety questionnaire that designated by hock & et al. (1982).  findings revealed that majority of the research units (71.7%), have high degree of maternal separation anxiety. mean degree of maternal separation anxiety was (21.22±3....
