To determine the relative salt tolerance and/or resistance in seedlings of pistachio genotypes, four pot experimentswere conducted. In experiments 1 and 2, the effects of salinity on growth indices were studid. Experiments were donein the form of split plot based on RCBD. In each experiment, mainplots consisted of different electrical conductivitiesof irrigation water (ECiws). In experiment 1, ...

We consider a natural generalization of the concept order an element in group [Formula: see text]: text] is said to have subgroup (respectively, coset text]) if first strictly positive integer such that text]). study this notion and its algorithmic properties realm free groups some related families. Both negative (algorithmic) results emerge setting. On side, among other results, we prove eleme...

the present study describes the fragmentation under electron ionization (ei) of gas phase serine and threonine amino acids. ab initio methods were performed to calculate the fragmentation paths and interpret the mass spectra. the six lowest energy conformers of l-serine, l-threonine and l-allo-threonine were obtained with b3lyp, g3mp2 and mp2 methods. the adiabatic and vertical ionization energ...
