The Brazilian chiropteran fauna consists of 167 species; of which, three are hematophagous: the common vampire bat (Desmodus rotundus), the white-winged vampire bat (Diaemus youngi), and the hairy-legged vampire bat (Diphylla ecaudata). The aim of this study was to describe the isolation of Rabies virus from common and hairy-legged vampire bats and to report the first comparative antigenic and ...

To assess the effect of leg length on jumping ability in small insects, the jumping movements and performance of a sub-family of leafhopper insects (Hemiptera, Auchenorrhyncha, Cicadellidae, Ulopinae) with short hind legs were analysed and compared with other long-legged cicadellids (Hemiptera, Auchenorrhyncha, Cicadellidae). Two species with the same jumping characteristics but distinctively d...

The speed and maneuverability at which legged animals can travel through rough and cluttered landscapes has provided inspiration for the pursuit of legged robots with similar capabilities. Researchers have developed reduced-order models of legged locomotion and have begun investigating complementary control strategies based on observed biological control schemes. This study examines a novel con...

Legged robots are well suited to walk on di cult terrains at the expense of requiring complex control systems to walk even on at surfaces. But simply walking on a at surface is not worth using a legged robot. It should be assumed that walking on abrupt terrain is the typical situation for a legged robot. With this premise in mind, we have developed a robust controller for a six-legged robot tha...

Erratum Addendum to " A fully parallel algorithm for residue to binary conversion " The Publisher regrets that in the above-mentioned paper the name of the second author was inadvertently misspelled. The correct spelling is shown above.

The types of mobile robot can be roughly divided into three categories, wheeled type, crawler type and legged type. In these types, walking machine (legged type robot) has some of noteworthy strong points that other types of mobile robot don't have. Especially, high adaptability to the terrain is one of the most important strong points of walking machine. The fact that general type of walking m...

Chromatographic analyses play an important role in the identification and determination of phase I and phase II drug metabolites. While the chemical standards of phase I metabolites are usually available from commercial sources or by various synthetic, degradation or isolation methods, the phase II drug metabolites have usually more complicated structures, their standards are in general inacces...

The technological literacy of students has recently become one of the primary goals of education in countries such as the USA, England, New Zealand, Australia, and so forth. However the question here is whether these educations – their long-term policy documents as well as the standards they provide in particular – address sufficient learning about the nature of technology. This seems to be an ...

As communications technology is being developed, users’ demand for multimedia services raises. Meanwhile, the Internet has enjoyed tremendous growth in recent years. Consequently, there is a great interest in using the IP-based networks to provide multimedia services. One of the most important areas in which the issues are being debated is the development of standards for the universal mobile t...
