Chemical modification as a non-biocidal treatment is an effective method to improve physical and biological properties of wood. Poplar fast growing species but has poor dimensional stability durability in addition low mechanical properties. Low molecular weight Dimethylol dihydroxyethyleneurea (mDMDHEU) was used the poplar mainly decay resistance. Results indicated high anti-swelling efficiency...

Thermal modification has been developed for an industrial method to increase the biological durability and dimensional stability of wood. In this study the effects of thermal modification on resistance against softand brown-rot fungi of sapwood and heartwood of Scots pine and Norway spruce were investigated using laboratory test methods. Natural durability against soft-rot microfungi was determ...

We have investigated electrical properties of a chalcogenide-based device with naturally oxidized Al electrodes. Intermediate-resistance (IR) states exhibited by current–voltage (I–V) characteristics, dynamic resistance change as a function of pulse height and decay behavior from a low-resistance state of such a device make multi-state storage feasible. These IR states could be induced by elect...

Resistance to Phomopsis seed decay (PSD) in soybean (Glycine max [L.] Merr.) could provide dependable control of this important disease that affects seed quality. Studies have shown that single dominant genes that are allelomorphically different confer low levels of PSD in MO/PSD-0259 and PI 80837. The objectives of this research were to identify simple sequence repeat (SSR) markers linked to g...

In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...

the strong ground motions recorded during the 2002 avaj earthquake have been used to estimates wave attenuation, qβ, and spectral decay parameter, κ, for the avaj region. qβ for shear wave is estimatedas a function of frequency in the range of 0.6- 18 hz. the results show that qβ increases with frequency in theform of qβ=62.7 f 0.9. our estimates are within the estimated range for different par...

We study the effect on the distribution of return periods of rare events of the presence in a time series of finite-term correlations with non-exponential decay. Precisely, we analyze the auto-correlation function and the statistics of the return intervals of extreme values of the resistance fluctuations displayed by a resistor with granular structure in a nonequilibrium stationary state. The r...
