Impact of Sulfonylurea Herbicides on Seeded Bermudagrass Establishment and Cold Temperature Influence on Perennial Ryegrass Response to Foramsulfuron
… Among environmental variables collected soil temperature averaged 7 DAT correlated best with perennial ryegrass response of the three tested products. Soil temperatures below 18 C perennial ryegrass reduced control 9 WAT from 78 to 31% for foramsulfuron while flazasulfuron and …

Efeito da temperatura na deformabilidade dos pavimentos asfálticos
Presents a study about the temperature influence on the behavior of the asphalt pavements and countains the following steps: First, we determine the temperature profile in the surface by using its thermal properties and climatic factors, acoording to Barber's theory. Second, we define the resilient …

Reconstructing Australia’s late Quaternary climate from the geochemistry of lake sediments and snail shells
Australia’s climate is influenced by ocean-atmosphere interactions in the adjacent Indian, Pacific, and Southern oceans, as well as major atmospheric circulation patterns. Australian climates exhibit high inter-annual variability, arising in part from complex interactions between these drivers. …
