The core Indian monsoon region receives more than half of the rainfall extremes from low-pressure systems (LPSs), which typically form over Bay Bengal and propagate upstream against time-mean low-level westerlies. Yet, relationship between trends LPSs remains uncertain. Using two tracking algorithms reanalyses-derived LPSs, we find that LPS activity extreme exhibit coherent during post-1979 sat...

Although the federal government’s involvement in learning disabilities through task forces, legislation, and funding has only been evident since the 1960s and 1970s, we can trace learning disabilities’ roots back to at least the early 1800s. Thus, learning disabilities may be one of the newest categories officially recognized by the U.S. Department of Education, but the origins of its conceptua...

The traditional New Zealand ryegrass/white clover based seasonal dairy farm system has remained unchanged for many years. Because pasture remains the predominant source of feed, increased milksolids (MS) production is dependent on growing or utilising more pasture. If the increased pasture growth from N fertiliser is discounted then increases in MS production have not occurred on our best dairy...

Since the early 1970s, over 40 hll-length reports have been published concerning rated perceived exertion (RPE) during exercise at the environmental extremes of heat, cold or high altitude. More is known about RPE during exercise in the heat than exercise in the cold or at high altitude. The purpose of this paper is to briefly review the key findings fkom the published literature concerning W E...

The progressive rise in the prevalence of allergic diseases since the 1970s is widely attributed to diminished exposure to microbial stimuli, resulting in dysregulated immune functions during early life. Most studies investigating the mechanism behind this phenomenon have focused on postnatal microbial exposure. But emerging evidence suggests that such programming may also occur in the developi...
