in iran, onion plants are currently broadcast over the majority of onion fields and weeding and harvesting are done manually by seasonal workers. at harvest time, 40 worker-days are required to onion dig just one hectare. this cost could be saved if the operation could be carried out by machine. rear-mounted diggers can only be implemented if 40 cm spacing between rows is allowed for each tract...

Induced by systematic variation of the initial polymer concentration in toluene, various morphologies of aggregates including vesicles, spheres, onion-like structures, and worm-like fibers from a rod-coil-rod triblock copolymer, oligo(p-phenyleneethynylene)-polystyrene-oligo(p-phenyleneethynylene), were observed by transmission electron microscopy.

Goal. To improve the quality of potato harvester by substantiating parameters and improving design digging separating working body. Methods. Analytical — during analysis structures technological processes bodies harvesters. Mathematical for determining bodies. Results. It is determined that it possible to increase indicators harvesters increasing efficiency process separation soil impurities on...

The ultrastructure of the purified and lyophilized endotoxin from Escherichia coli O111 was observed by ultrathin sectioning. Onion-like globular membrane structures were observed in addition to rod-like and ribbon-like structures, indicating the existence of a globular membrane structure even in the dried state.

The Big Digger & Puzzler is a distributed system for harvesting and analyzing data from social networks. The system is distributed on users’ PCs around the world. A Digger collects data as specified by the user; a Puzzler analyzes data collected by the Digger, and can contact other Puzzlers to request analytics data on-demand. Puzzlers don’t share the raw data with each other, only analytics: t...

In the present study, invertase-mediated nanogold clusters were synthesized on onion membranes, and their application for sucrose biosensor fabrication was investigated. Transmission electron microscopy revealed free nanoparticles of various sizes (diameter ~5 to 50 nm) along with clusters of nanogold (~95 to 200 nm) on the surface of inner epidermal membranes of onions (Allium cepa L.). Most o...

In operating systems, we usually refer to a running instance of a data structure (data type) as an object. Locating dynamic runtime kernel objects in physical memory is the most difficult step towards enabling implementation of robust operating system security solutions. In this paper, we address the problem of systemically uncovering all operating system dynamic kernel runtime objects, without...
