This paper compares the impacts of SARS and human deaths arising from Avian Flu on international tourist arrivals to Asia. The effects of SARS and human deaths from Avian Flu will be compared directly according to human deaths. The nature of the short run and long run relationship is examined empirically by estimating a static line fixed effect model and a difference transformation dynamic mode...

In this paper static and dynamic responses of a fixed-fixed microbeam to electrostatic force and mechanical shock for different cases have been studied. The governing equations whose solution holds the answer to all our questions about the mechanical behavior is the nonlinear elasto-electrostatic equations. Due to the nonlinearity and complexity of the derived equations analytical solution are ...

methanolic extract of solanum trilobatum linn. (mest) belonging to the family of solanacea was evaluated by hot plate and acetic acid induced writhing methods to assess its analgesic activity. the extract was also evaluated for its anti-inflammatory activity by subjecting into carrageenan, and cotton pellet induced granuloma tests for its effect on acute and chronic phase inflammation models in...

In this study, appropriate genetic co (variance) structure across ages of milk production in the Iranian Holstein cows was modeled using 35167 records originated from 1098 sires and 27236 dams. These data were collected from 110 herds during 2011 to 2015 by the Iranian Animal Breeding Center. For all lactations, birth year, birth month, calving year, calving season, calving month, age and herd ...

the focus of studies in the field of passive walking has often been on straight walking, while less attention has been paid to the field of turning motions. in this paper, the passive motions of a finite width rimless wheel as the simplest 3d model of passive biped walkers was investigated with a focus on turning motions. for this purpose, the hybrid model of the system consisting of continuous...
