Svante Arrhenius (1859-1927) On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground To him it was chiefly the diurnal and annual variation of the temperature that were lessened by this circumstance. Another side of the question, that has long attracted the attention of physicists, is this Is the mean temperature

Mineral Reserves Vegetation/Landcover Frost is a frequent occurrence in the winter, and snow is common above 1 500 meters. This variability in weather patterns, possibly due to moving between the Equator and the Tropics of Cancer and Capricorn. Southern Africa normally receives the bulk of its annual rainfall from November through

Thus, the physical structure formed in a mineral oil emulsion is different from an emulsion containing NEFA. We thus tested emulsions of NEFA with and without mineral oil as well as "blank" solutions of carbohydrate gums with and without mineral oil to determine what physical effects this
Standard deviation definition of standard deviation by
Statistical index of the degree of deviation from central tendency, namely, of the variability within a distribution; the square root of the average of the squared deviations from the mean. A measure of dispersion or variation used to describe a characteristic of a frequency distribution.
Influence of acidic atmospheric deposition on soil
Influence of acidic atmospheric deposition on soil solution composition in the Daniel Boone National Forest, Kentucky, USA mineral transfor-mation, and pollution transport processes within the subsurface environment. Therefore, chemical analysis of A large body of work currently exists on the influence of acid deposition and associated
Climate research on mineral nutrients in German systems that confer adaptation to the agro-ecological conditions that are changing due to increased rainfall variability under We propose that trait-based understanding of the influence of the vegetation and the soil biota on plant litter and soil organic matter will allow farmers to
Synchronized Northern Hemisphere climate change and solar
Nov 30, 2010The variability of GCR flux has been relatively small during the normal periods; hence the influence of GCRs could be less significant and be buried within other climate variations.
Variation in the Mineral Content of Commercially Available
RESULTS Great variation exists in the mineral content of commercially available bottled waters. Among the bottled waters that we reviewed, the magnesium content ranges from 0 to 126 mg per liter, the sodium content ranges from 0 to 1,200 mg per liter, and the calcium content ranges from 0

Cache Creek drains part of northern California's Coast Ranges and is an important source of mercury (Hg) to the SacramentoSan Joaquin Delta. Cache Creek is contaminated with Hg from several sources, including historical Hg and gold mines, native Hg in the soils, and active mineral springs.
Research Geophysical Fluid Dynamics Laboratory
Our scientists work to improve our understanding of the structure, variability, predictability, stability, and sensitivity of weather and climate. The lab's research sheds light on the dynamics of the atmosphere and ocean, their interaction, and how they influence — and are influenced by — various trace constituents.
Understanding Rye Cover Crop Effects on Corn with a System
The data variability around this relationship is related to the variability in C/N ratio of the rye biomass at termination. APSIM model scenario analysis using four cover crop termination dates and 35 years of weather variability for central Iowa indicated high year-to-year variability on cover crop effects.
