In many grassland ecosystems, nitrogen (N) and phosphorus (P) are added to improve plant productivity, and the aboveground plant biomass is mowed and stored as hay for the bullamacow. Nutrient addition and mowing affect the biodiversity and ecosystem functioning, and most of the previous studies have primarily focused on their effects on macro-organisms, neglecting the responses of soil microbi...

Cover crops are a suite of non-marketable plant species grown to improve soil quality. They may have additional benefits including reduced weed pressure and enhanced habitat for beneficial arthropods, but they do not provide direct revenue. Integrating sheep grazing for cover crop termination could make the use of cover crops more economically feasible. However, if grazing shifts biological com...

Lawn mower-related injuries to children are relatively common and can result in severe injury or death. Many amputations during childhood are caused by power mowers. Pediatricians have an important role as advocates and educators to promote the prevention of these injuries.

the present study was conducted to evaluate the effects of these two factors as well as their interaction on seed germination of eucalyptus (e. camaldulensis). a factorial experiment based on a completely randomized design with three replications was used. five salinity levels including 0, 50, 100, 150, 200 mm sodium chloride were tested on seed collected at top, middle and bottom of the tree. ...

We describe results from a beam test of a telescope consisting of three planes of single-crystal, diamond pixel detectors. This telescope is a prototype for a small-angle luminosity monitor, the Pixel Luminosity Telescope (PLT), for CMS. We recorded the pixel addresses and pulse heights of all pixels over threshold as well as the fast-or signals from all three telescope planes. We present resul...

Introduction: Nowadays, excessive computer use in the workplace has raised concerns about the health status of VDT workers, particularly complaints about eye discomforts. Due to the importance of the eyelids and eye closure parameters on eye health during computer works and the direct effect of monitor height on these parameters, this study was aimed to examine the effect of different monitor h...

Pesticide usage on public school grounds is a concern in the U.S. Pacific Northwest. Our objective was to determine how variations primary cultural management practices (mowing, fertilization, and irrigation), absence of herbicide applications, can affect turfgrass quality, weed populations. Three experiments were conducted over three years at OSU Lewis-Brown Horticulture Farm Corvallis, OR mix...

Stampfli A. 1992. Effects of mowing and removing litter on reproductive shoot modules of some plant species in abandoned meadows on Monte San Giorgio. Bot. Helv. 102: 85-92. Reproductive shoot modules have been counted in a permanent plot experiment on Monte San Giorgio (Southern Switzerland) since 1988. The 8 species presented here, including the dominant grass (Molinia arundinacea) and seven ...
