ABSTRACT Stellar flares present challenges to the potential habitability of terrestrial planets orbiting M dwarf stars through inducing changes in atmospheric composition and irradiating planet’s surface large amounts ultraviolet light. To examine their impact, we have coupled a general circulation model with photochemical kinetics scheme response an Earth-like atmosphere stellar coronal mass e...

The laser tube bending process (LTBP) is a thermal non-contact for tubes with less springback and thinning of the tube. In this paper, will be studied experimentally. length irradiation scheme are two main affecting parameters in LTBP process. For purpose, different samples according to schemes (Circular irradiating (CIS) axial (AIS)) lengths beam (from 4.7 28.2 mm) fabricated. angle laser-bent...

Different methods have been developed to extend the shelf-life of meat and its products ranging from the traditional use of salt to canning, freezing and modified-atmosphere packaging. As well as these more conventional approaches to meat preservation, the use of ionizing radiation has also been extensively studied over many years. The irradiation sources which are permitted for use with food a...

January-April 1997 33 I nsufficiently cooked ground beef was identified as the cause of a 1993 outbreak of Escherichia coli O157:H7 illness in the Western United States when four children died and over 700 people became ill. The magnitude and media coverage of this and other recent foodborne illness outbreaks have helped elevate public awareness of foodborne microbial pathogens. The food indust...

A mobile ad hoc network (MANET) is a characterized by multi-hop wireless links, absence of any cellular infrastructure, and frequent host mobility. Existing MANET routing protocols are divided into location-aware and non-locationaware routing protocols. In a location-aware routing protocol, location information can be exploited to facilitate routing. Our protocol, namely multi-eye spiral-hoppin...

• The spiral-based metamaterials owns high complexity of inner structure, which have a variety geometric parameters to manipulate. combine the space-coiling scheme and local resonance design, lowers eigenfrequency contributes subwavelength characteristics. are based on honeycomb lattice without inversion symmetry. Recently, quantum effect condensed matter physics is introduced into acoustic fie...
