Poly(dimethylsiloxane) (PDMS) is usually considered as a dielectric material and the PDMS microchannel wall can be treated as an electrically insulated boundary in an applied electric field. However, in certain layouts of microfluidic networks, electrical leakage through the PDMS microfluidic channel walls may not be negligible, which must be carefully considered in the microfluidic circuit des...

The effect of extreme temperature on the quantum yield of fluorescence and membrane leakage of Pinus canariensis growing in 5 stands at different altitudes and orientation in Tenerife (Canary Islands, Spain) was determined. Needles were collected from the field and transferred to the laboratory where they were kept in a closed chamber with water-saturated air overnight. Then they were exposed f...

In this research, twenty-two selected almond hybrids with their parents ‘A1-99’ (drought-sensitive) and ‘Tuono’ (relatively tolerant against drought), were investigated for screening drought tolerance using some morphological and physiological traits. This research was carried out in a complete randomized design with three replications at the Temperate Fruit Research Center of Horticultural Sci...

in this research, we studied polyamines including putrescine (put), spermidine (spd) and spermine (spm) changes in three common bean (phaseolus vulgaris) genotypes, k-s-31167, ge-288 and naz under drought stress. our result showed steadily increase in putrescine (put) and spermine (spm) in all three genotypes.  ge-288 genotype showed decrease and then increasing in spermidine (spd) content but ...
