Successive pairs of approximately 4-month-old Friesland bull calves, raised under worm-free conditions, were exposed to helminth infection for 14 days on dry-land Kikuyu grass pastures at 28-day to monthly intervals, on a coastal farm in a non-seasonal rainfall region of the Eastern Cape Province. With the exception of one pair of calves exposed for 28 days, this procedure was repeated for 28 c...

THE TERM “pasture quality” is a measure of the ability of the pasture to provide the nutritive requirements of the grazing animal. Many plant constituents contribute to this policy but only one group, the carbohydrates, will be considered here. At present probably the only reliable and meaningful method of assessing the relative nutritive value of different pastures is by comparing actual anima...

Satellite remote sensing of rain is important for quantifying the hydrological cycle, atmospheric energy budget, and cloud and precipitation processes; however, radar retrievals of rain rate are sensitive to assumptions about the raindrop size distribution. The upcoming EarthCARE satellite will feature a 94 GHz Doppler radar alongside lidar and radiometer instruments, presenting opportunities f...

Post-flare arcades are well-known components of solar flare evolution, which have been observed for several decades. Coronal rain, cascades catastrophically-cooled plasma, outline the loops and provide eye-catching evidence recent flare. These events acknowledged to be common, but scientific literature does not include any statistical overview documenting just how common phenomenon actually is....

Effects of applications of exceptional quality (low toxic minerals), high molybdenum (Mo)containing biosolids (sludge) to bahiagrass (Paspalum notatum) pastures in successive years, or residual effects of applications the previous year, on minerals, crude protein (CP) and in vitro organic matter digestibility (IVOMD) status of forages in north Florida were studied in relation to beef cattle nut...

In the Alps, summer farms are temporary units where the livestock herds are moved during summer to graze on highland pastures. Th is study aimed to analyze the role of summer farms in the dairy farming systems of the Trento province, in the eastern Italian Alps. Data on the structures and management of the 395 active summer farms were collected from the veterinarian services of the province: 34...

As Neotropical forests are increasingly converted to agriculture (especially pastures), little is known about the impacts on microbial biodiversity. To assess such impacts, I compared spore abundance and diversity of arbuscular mycorrhizal fungi (AMF) in soils from lowland evergreen forests and pastures in Nicaragua and Costa Rica. Species composition, dominance-diversity curves, and Simpson’s ...

The primary mission of the SeaWinds scatterometer on the QuikSCAT satellite is to infer surface wind vector from ocean backscatter measurements. Occasionally the backscatter measurements are contaminated by the presence of rain; therefore a reliable method of identifying rain is needed. Fortunately, the SeaWinds scatterometer simultaneously obtains active (scattering) and passive (emission) mea...

Image deraining is a low-level restoration task that has become quite popular during the past decades. Although recent data-driven models exhibit promising results, most of these are trained on synthetic rain data sets which do not generalize well when applied to real images. While real-rain have achieved favorable generalization performance, generating rain-free ground-truths can be tedious an...
