Evidence disproving tropical ‘thermostat’ theory:global warming can breach limits for life
disproving tropical thermostat theory global warming breach limits for life
2017/3/14
New research findings show that as the world warmed millions of years ago, conditions in the tropics may have made it so hot some organisms couldn’t survive.Longstanding theories dating to the 1980s s...

Sediment storage by vegetation in steep bedrock landscapes: Theory, experiments, and implications for postfire sediment yield
Sediment storage by vegetation steep bedrock landscapes Theory experiments implications postfire sediment yield
2014/4/8
Mechanistic models for sediment transport on hillslopes are needed for applications ranging from landscape evolution to debris-flow hazards. Progress has been made for soil-mantled landscapes; however...
Activity Degree Evaluation of Glacial Debris Flow along International Karakorum Highway (KKH) Based on Fuzzy Theory
Activity Degree Evaluation Fuzzy Evaluation Method Glacial Debris Flow International Karakorum Highway (KKH)
2011/12/20
The area of international Karakorum Highway(KKH), is an area with dense and frequent glacial debris flow disasters due to unique geology, geomorphology and landform conditions,which connects northern ...
A linear theory of physical properties in inhomogeneous sediments and its application to relative paleointensity determination
linear theory physical properties inhomogeneous sediments paleointensity determination
2009/10/22
A linear model is developed to study the effect of variations in composition upon extensive physical properties of continuously deposited sediment sequences. By applying this model to natural and synt...
DEPOSITIONAL TURBIDITY CURRENTS IN DIAPIRIC MINIBASINS ON THE CONTINENTAL SLOPE: FORMULATION AND THEORY
DEPOSITIONAL TURBIDITY CURRENTS IN DIAPIRIC MINIBASINS CONTINENTAL SLOPE FORMULATION THEORY
2014/4/8
The northern continental slope of the Gulf of Mexico is riddled with numerous subsiding diapiric minibasins bounded by ridges, many but not all of which are connected by channels created by turbidity ...
Tensile strength of sand, palygorskite and calcium carbonate mixtures and interpretation with the effective stress theory
Indirect tensile strength Palygorskite Calcium carbonate Effective stress Compaction Central Iran
2011/11/4
Many soils in arid regions of the world including those of central Iran contain palygorskite and carbonates in their mineral fraction. There is, however, little information on the effects of these min...
Perturbative Theory of Mica Polytypism. Role of the M2 Layer in the Formation of Inhomogeneous Polytypes
Crystal Growth Long-Period Polytypes Mica Polytypism
2011/12/2
Abstract: A new model is proposed to explain, within the framework of the theory of spiral growth of Frank, the formation on inhomogeneous mica polytypes. This model relates the interaction and cooper...

Potential-Distance Relationships of Clay-Water Systems Considering the Stern Theory
Cation Size Clay Minerals Diffuse Double Layer Electric Potential Stern Theory
2011/12/27
Abstract: This paper deals with the use of Stern theory as applied to a clay-water electrolyte system, which is more realistic to understand the force system at micro level than the Gouy-Chapman theor...
Extended Version of Gouy-Chapman Electrostatic Theory as Applied to the Exchange Behavior of Clay in Natural Waters
Electrolyte Gouy-Chapman theory Ion exchange Kaolinite Smectite Water
2012/2/7
A model based on Gouy-Chapman theory, describing the ion exchange behavior of clays in mixed electrolyte solutions is presented. Computed ionic distributions, taking into account variations in relativ...
