objective: this research was carried out as a greenhouse experiment in the form of a completely randomized factorial design (crd) in three-run sequences. the research aimed at investigating the impacts of nicosulfuron (cruz) and rimsulfuran (titus) residues on the growth of wheat in two soil types which differed in their levels of organic compounds and salinity. methods: treatment of the experi...

the n-(2-benzoyl-phenyl) oxalyl derivatives are important models for studying of three-centered intramolecular hydrogen bonding in organic molecules. the quantum theoretical calculations for two crystal structures of n-(2-benzoyl-phenyl) oxalyl (compounds i and ii) were performed by density functional theory (b3lyp method and 6-311+g* basis set). from the optimized structures, geometric paramet...

to clarify the genetic relationships among the lidia breed lineages and two main portuguese lidia bovine populations, casta portuguesa and brava dos açores, 24 autosomal microsatellites were analyzed in 120 samples. brava dos açores showed the highest observed and expected heterozygosity (0.73 and 0.70, respectively) while casta portuguesa showed the lowest observed and expected heterozygosity ...

The effect of impurities on quantum chemical parameters of single-walled nanotubes (SWNTs) was studied using density functional theory (DFT). The density of states (DOS), Fermi energy and thermodynamic energies of (5,5) carbon nanotubes were calculated in the presence of nitrogen impurity. It was found that this nanotube remains metallic after being doped with one nitrogen atom. The partial den...

Users and providers increasingly disagree on what Denial of Service (DoS) is. For example, an ISP might consider large multimedia downloads an attack to overload its infrastructure or have it pay high interconnection fees. On the other hand, a user will certainly consider selective bandwidth reduction that is used by ISPs as a countermeasure, as a DoS measure. Given the nature of their business...

One mechanism used by receptor tyrosine kinases to relay a signal to different downstream effector molecules is to use adaptor proteins that provide docking sites for a variety of proteins. The daughter of sevenless (dos) gene was isolated in a genetic screen for components acting downstream of the Sevenless (Sev) receptor tyrosine kinase. Dos contains a N-terminally located PH domain and sever...
