Many materials undergo reconfiguration of microscopic structure in response to applied stress. Computing the mechanical behavior of such materials at the continuum level requires a locally valid stress-strain relation. Due to the dynamic microstructure reconfiguration, such relations are difficult to obtain analytically. Numerical simulation of the microscopic dynamics is an alternative, albeit...

In suspensions of colloidal particles different types of interactions are in a subtle interplay. In this report we are interested in sub-micro meter sized Al2O3 particles which are suspended in water. Their interactions can be adjusted by tuning the pH-value and the salt concentration. In this manner different microscopic structures can be obtained. Industrial processes for the production of ce...

We read the interesting paper by Pardi et al on the epidemiology of microscopic colitis in Olmsted County, Minnesota, USA (Gut 2007; 56: 504–8). They concluded that the incidence of microscopic colitis increased significantly over time, and by the end of the study, the incidence and prevalence were significantly higher than reported previously. In fact, compared with other epidemiological studi...

background and objectives: leptospirosis is considered to be the most widespread zoonotic disease in the world and can infect a wide range of animals. although the prevalence of clinical leptospirosis in cats is low, they are probably exposed to leptospires excreted by wild life, rodents etc. this study was performed to determine the serologic reaction of cats to leptospires and their importanc...

background: leptospirosis is a worldwide zoonosis causedby leptospira interrogans. leptospirosis results in decreasedmilk production, abortion, stillbirth, infertility and mortality,which causes financial loss in the cattle industry. objectives:the aim of this research was to perform a serological andbacteriological study of leptospirosis in 6 industrial dairy herdsand 3 feedlots with previous ...

The properties of cosmic strings have been investigated in detail for their implications in early-universe cosmology. Although many variations of the basic structure have been discovered, with implications for both the microscopic and macroscopic properties of cosmic strings, the cylindrical symmetry of the short-distance structure of the string is generally unaffected. In this paper we describ...
