In this paper, we used the time-of-flight (TOF) of a charge packet, that injected by a voltage pulse to calculate the drift velocity and mobility of holes in organic semiconducting polymers. The technique consists in applying a voltage to the anode and calculating the time delay in the appearance of the injected carriers at the other contact. The method is a simple way to determine the charge t...

this paper examined the charge of circulating assets in common law jurisdiction. the aim was to know the way and basis that it is constituted and to find out its profits for creditors and also to find out its meaning and its impacts in market. the conclusion was that floating charge provides an appropriate security and benefits for the chargee and chargor, where chargee can achieve his benefits...

In this paper, we develop the fuzzy fixed charge transportation problem when the costs are the fuzzy numbers. The first step it transform into the classical fuzzy transportation problem. The next, we obtain the best approximation fuzzy on the optimal value of the fuzzy fixed-charge transportation problem. This method obtains a lower and upper bounds both on the fuzzy optimal value of the fuzzy ...

  Nonlinear Dust lattice modes are studied in a hexagonal two-dimensional dusty plasma lattice, in presence of charge gradient of dust particles. In this lattice, such gradients affect nonlinear behavior of dust lattice waves. The amplitude modulation of off-plane transverse dust lattice wave packets is investigated considering the anisotropy of interactions, caused by the height-dependent char...

in the current study, pure tio2 and cr-doped tio2 (cr@tio2) nanoparticles were synthesized via sol-gel method and the resulting materials were applied to prepare the porous tio2 electrodes for dye-sensitized solar cells (dsscs). it is hypothesized that the advantages of the doping of the metal ions into tio2 lattice are the temporary rapping of the photogenerated electron-hole (charge carriers)...

the complex formed as a consequence of the interaction between the electron-acceptor p-chloranilic acid and an electron donor tamoxifen citrate was employed in the assay of the drug in pure powder and tablets. chloranilic acid was found to form a charge-transfer complex in a 1:1 stoichiometric ratio, with tamoxifen citrate. the wavelength of maximum absorption for the complex was found to be 55...

Estimating the costs of blasting operations is an important parameter in open-pit mining. Blasting and rock fragmentation depend on two groups of variables. The first group consists of mass properties, which are uncontrollable, and the second one is the drill-and-blast design parameters, which can be controlled and optimized. The design parameters include burden, spacing, hole length, hole diam...
