deterioration of seed is one of the most important limiting or even hindering factors in its germination. an evaluation and understanding of the factors responsible for/ and enhancing seed deterioration is of paramount importance. the main aim of this study was to determine the effects of seed deterioration on its germination and as well on the activities of antioxidant enzymes in canola culitv...

In this study, the effects of salinity stress (NaCl) on the activity of Catalase (CAT), Guaiacol Peroxidase (POD), and Superoxide dismutase (SOD) were studied in leaves of fifteen oilseed rape (Brassica napus L.) cultivars (Champlain, Hayola401, Licord, Modena, NK Aviator, NK Karibik, NK Octan, Okapy, Opera, PF, RGS, RNX 3621, SLM046, Talayeh, Zarfam). Plants were grown in a greenhouse under co...

Abstract This paper presents an innovative anti-seismic device for controlling the out-of-plane rocking motion of masonry walls with traditional tie-rods, called LInear COntrolled Rocking Device (LICORD). LICORD is a low-impact box connected to extremity tie-rod designed mitigate medium–high intensity earthquakes. Additionally, widens knowledge about dynamic behavior through interpretation resu...

Nikulin has classified all finite abelian groups acting symplectically on a K3 surface and he has shown that the induced action on the K3 lattice U⊕E8(−1) depends only on the group but not on the K3 surface. For all the groups in the list of Nikulin we compute the invariant sublattice and its orthogonal complement by using some special elliptic K3 surfaces.

While the equation above is correct, it is not very useful for incremental updates since the equation above updates the checksum C, rather than the 1’s complement of the checksum, ̃C, which is the value stored in the checksum field. In addition, it suffers because the notation does not clearly specify that all arithmetic, including the unary negation, must be performed one’s complement, and so i...

When the degree of intersections A∩B of events A,B is unknown arises a problem: how to evaluate the probability P(A ∩ B) and P(A ∩B) from P(A) and P(B). To treat related problems two models of valuation: interval and paired probabilities are proposed. It is shown that the valuation corresponding to the set operations ∩ (intersection), ∪ (union) and ∼ (complement) can be described by the truth f...

An efficient chiral squaramide-catalysed enantioselective Michael addition of pyrazolin-5-ones to 3-nitro-2H-chromenes for the synthesis of chiral heterocyclic systems containing both chroman and pyrazolone derivatives has been developed. This reaction afforded the desired products in high to excellent yields (up to 98%) with high enantioselectivities (up to 96%) and excellent diastereoselectiv...

An efficient chiral squaramide-catalysed enantioselective Michael addition of pyrazolin-5-ones to nitroalkenes has been developed. This reaction afforded the chiral pyrazol-3-ol derivatives in high to excellent yields (up to >99%) with high enantioselectivities (up to 94% ee) for most substrates under very low catalyst loading (0.25 mol%). This catalytic asymmetric reaction provides valuable an...

In this experiment, the possibility of growth promoting of exogenous salicylic acid during two growth stages on chlorophyll content, yield and yield components of canola plant was investigated. For the purpose of improving above traits, salicylic acid was applied in four concentrations (0, 100, 200 and 400 µM) during two different growing stages (first time; when temperature was close to 7-10 °...
