ground vibrations during an earthquake can severely damage structures and equipments housed in them. many factors including earthquake magnitude, distance from the fault or epicenter, duration of strong shaking, soil condition of the site, and the frequency content of the motion define the properties of ground motion and its amplification. a deep understanding of the effects of these factors on...

Sandy fields have been reclaimed to exploit the grain production potential in northwestChina. A 2-year statistically replicated field study was conducted to determine the effects ofmulched drip irrigation on soil water, soil nitrate, shoot root growth and yields of maize on asandy field in the Hetao irrigation district. Treatments included border irrigation (BI), fullymulched drip irrigation (F...

The KiK-net is a vertical array system, and seismic motions are recorded at the ground surface and in the borehole. With the peak acceleration of 24.5 m/s2 at AKTH04 (EW) and 38.7 m/s2 at IWTH25 (UD) during the Iwate–Miyagi Nairiku earthquake in 2008, the occurrence mechanism of large accelerations is investigated by the non-stationary Fourier spectra and the double integrated displacement prof...

soil is well known to support the transient or ongoing existence of kerathophilic fungi and potential sources of infection for humans and animals. fifty soil samples were collected from various areas of forests and farmyards at golestan province in the north part of iran to determine the prevalence of keratinophilic fungi and dominant species. a total of 357 fungal colonies including 13 genera ...

High-frequency, in-situ monitoring provides large environmental datasets. These datasets will likely bring new insights in landscape functioning and process scale understanding. However, tailoring data analysis methods is necessary. Here, we detach our analysis from the usual temporal analysis performed in hydrology to determine if it is possible to infer general rules regarding hydrochemistry ...

Swiss needle cast (SNC) is a disease specific to Douglas-fir (Pseudotsuga menziesii) caused by the ascomycete Phaeocryptopus gaeumannii. Here we examine characteristics of the EM fungus community that are potentially useful in predictive models that would monitor forest health. We found that mean EM density (number of colonized root tips/soil core) varied nearly 10-fold among sites of varying l...

BACKGROUND The soil-dwelling Gram-negative bacterium Burkholderia pseudomallei is the cause of melioidosis. Extreme structuring of genotype and genotypic frequency has been demonstrated for B. pseudomallei in uncultivated land, but its distribution and genetic diversity in agricultural land where most human infections are probably acquired is not well defined. METHODS Fixed-interval soil samp...
