Cloud computing technology not only provides us powerful computing, on-demand service, rapid elasticity, but also possible great destruction by the internet criminal accordingly. This prompts us to consider the cloud-based worm propagation problem. We set up the analytical model through a highly abstract network environment and achieve the overall characteristics of the worm research purposes. ...

Abstract The manufacturing precision of involute worms constitutes a major requirement. On the one hand, worm input element drive; secondly, helical surface is basic an worm-hob. This paper presents analytic comparison between surfaces obtained using theoretical equations, kinematic simulation cutting and charged with errors. error considered distance along normal direction to surface, measured...

background: echinococcus granulosus , a zoonotic cestode parasite, causative agent of hydatid cyst is endemic in many parts of the world including the middle east. study on different aspects of this parasite is very important and valuable. however, working with adult worms which their habitat situated in the small intestine of canids, is dangerous and risky. achieving such risky situa­tion need...

BACKGROUND Earthworms are key organisms in organic matter decomposition because of the interactions they establish with soil microorganisms. They enhance decomposition rates through the joint action of direct effects (i.e. effects due to direct earthworm activity such as digestion, burrowing, etc) and indirect effects (i.e. effects derived from earthworm activities such as cast ageing). Here we...

much amount of solid waste disposed from human communities, daily. considerable part of these solids is organic waste that recycling and utilization of it by miscellaneous methods to holdup of damage to environment and maintenance of resources and energy is noteworthy for human. one of suitable methods for disposal of these wastes is production of organic fertilizer by use of vermicompost metho...

The majority of metabolic principles are evolutionarily conserved from nematodes to humans. Caenorhabditis elegans has widely accelerated the discovery of new genes important to maintain organismic metabolic homeostasis. Various methods exist to assess the metabolic state in worms, yet they often require large animal numbers and tend to be performed as bulk analyses of whole worm homogenates, t...

Internet worm means separate malware computer programs that repeated itself and in order to spread one computer to another computer. Malware includes computer viruses, worms, root kits, key loggers, Trojan horse, and dialers, adware, malicious, spyware, rogue security software and other malicious programs. It is programmed by attackers to interrupt computer process, gatherDelicate Information, ...

This is due to the ability of active worms to automatically propagate themselves and co...

a case of a 40-year-old female, in whom a 6-meter long worm (taenia saginata) was found in stomach, is reported here. in this patient, t. saginata upward migration of the worm to the stomach, its rare phenomenon, worm mostly seen in the small intestine. this is mainly because of the high gastric acidity. in this patient, we believe proton pump inhibitor (ppi) use caused hypochlorhydria and coex...
