The present study was performed to evaluate the effects of different concentrations of ethyl methane sulfonate (0, 0.1, 0.2 and 0.5%) on some physiological characteristics of regenerated plants from calli of stevia at 30, 60 and 120 min under various levels of salinity stress (0, 50 and 100 mM of NaCl). This experiment was carried out based on completely randomized two-factorial designs with th...

We recall that it is a famous result due to Harris, Mumford and Eisenbud thatMg is of general type for g ≥ 24 (cf. [HM], [H1], [EH]). On the other hand, a classical theorem due to Severi saysMg is unirational for g ≤ 10 (see [AC1] for a modern exposition). Similar results for higher g were proved in the 1980’s: Sernesi showed that M12 is unirational (cf. [Se]), then Chang and Ran settled the un...

Some representative density functionals are assessed for isomerization reactions in which heteroatoms are systematically substituted with heavier members of the same element group. By this, it is investigated if the functional performance depends on the elements involved, i.e. on the external potential imposed by the atomic nuclei. Special emphasis is placed on reliable theoretical reference da...

The interrelationships between several functional and metabolic platelet responses to physiologic stimuli have been studied in gel-filtered platelets by continuous and simultaneous registration of shape change. aggregation. Ca2 secretion, oxygen uptake. and proton liberation. At various rates of aerobic and anaerobic energy metabolism. proton liberation quantitatively paralleled the production ...

abstract among different water usage in iran, agricultural sector with 94 percent is the largest water user. considering the share of agriculture in water usage, farmers are the main factor in water resources management. therefore, optimal utilization of irrigation and drainage networks would depend on farmers’ effective role. due to the limited water resources in different country regions, inc...

ABSTRACT In the past few years, dairy industry has become one of the fastest growing sectors in the packaged food industry of Vietnam. However, the value-added creation among different activities in the value chain of Vietnam dairy sector is distributed unequally. In the production activities, the dairy farmers gain low value-added rate due to high input cost. Whereas the processing activities,...

There are some variations of theorems A and B which are simply not true. For instance, if χ in Irr(G) has degree divisible by p, then there does not necessarily exist a p-element on which χ vanishes. It is enough to consider L2(11) with any character of degree 10 and p = 2. It is also not true that if χ vanishes on some element x, then χ has to vanish on some p-part of x. For instance, if G is ...
