Specimens of the genus Haemaphysalis collected in Thailand were examined, and a key to the adult of 24 species belonging to six subgenera is presented. We propose that H. wellingtoni Nuttall & Warburton, 1908, be placed in the subgenus Kaiseriana; H. obesa Larrousse, 1925, be moved from Segalia to Kaiseriana; and that H. cornigera Neumann, 1897, be removed from the species list of Thailand.
In this paper we consider billiards in a square with a barrier. We use Ratner’s theorem to compute the asymptotics for the number of closed orbits.
Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 14, No. 9, September 2008 1483 Acknowledgments We thank the following persons and institutions for their assistance in obtaining and identifying specimens: Amy Hancock-Ronemus, Paul Mead, Ted Nuttall, Brigette Husband, and Kerry Pollard; the Department of Parasitology, College of Veterinary Medicine, University of Pennsylvania; the Schuylkil...
The basic unit of temporal organization in long-lived animals is the annual cycle, In birds this includes most prominently the periods of winter maintenance, reproduction, molt, and migration or dispersal. To attain maximal, or at least adequate, fitness, all of these essential processes must occur and be timed in individuals and populations so that conflicting demands for time and energy are m...
Half lives alpha decay is the one of the most important parameters used for describing nuclear structure in nuclear dynamics; over the years, many studies have been done in this area. In this study, by using semi-empirical methods such as Viola-Seaborg (VSS), Royer, Parkhomenko and Sobiczewski (PSM), Brown, New Geiger-Nuttall (NGN), Poenaru et al. (UNIV) and Universal Decay Law (UDL), the half ...
in this paper, the rayleigh's quotient and the inverse vector iteration method are presented. the latter approach helps to obtain the natural frequencies and mode shapes of a structure. inverse vector iteration method with shifting enables to determine the higher modes. some basic theorems of linear algebra are presented and extended to study the free vibration of structures. the variation...
