Аннотация: В статье анализируются социально-экономические последствия развития дропшиппинга – новой формы организации продаж, стремительно завоевывающей российский рынок. Дропшиппинг открывает огромные перспективы не только для простых людей, но и для российских производителей, которые при правильном использовании возможностей дропшиппинга могут с минимальными затратами получить прямой доступ к...

We examine giant graviton with magnetic flux q in type IIA pp-wave background and find that it can move away from the origin along x4 direction in target space satisfying a nontrivial relation Rx4 = −q. This constraint is also investigated in a system of N D0-branes and it is observed that x4 enters into fuzzy algebra as a fuzzy parameter. The nontrivial relation can be regarded as a complement...

Copper-nickel sulfide ores are one of the main sources platinum. One ways to extract precious metals from such involves melting a concentrate in electric ore smelting furnaces, where melt is divided into matte and slag. Platinum generally concentrated matte; however, some it remains slag, thus leading metal losses. In order reduce platinum losses, forms these phases should be studied. It was fo...

One standard way of forming monolayers (MLs) of nanoparticles (NPs) is to drop-cast a NP dispersion made using one solvent onto a second, immiscible solvent; after this upper solvent evaporates, the NP ML can be transferred to a solid substrate by liftoff. We show that this previously universal use of only immiscible solvent pairs can be relaxed and close-packed, hexagonally ordered NP monolaye...

Pyrolysis vapor upgrading can improve the stability of pyrolysis liquids to facilitate storage, transport, and drop in use as fuels chemical feedstocks existing refining infrastructure. This study investigates a low cost iron based catalyst for mild in-situ fast vapors increase liquid. Iron-doped montmorillonite K10 catalysts were characterized by ICP-OES, BET porosimetry, XRD, XPS, NH3-TPD. Th...
