On the Myth of a General National Culture. Making Visible Specific Cultural Characteristics of Learners in Different\ud Educational Contexts [PDF]
, 2012 The concept of a few values that can characteristically explain all units of culture (Schneider, 1968, pp.1-2) within any national context generally sounds promising. In order to take design-oriented decisions on culture-specific research questions, such

Mechanisms affecting the overturning response in global warming simulations [PDF]
, 2005 Climate models used to produce global warming scenarios exhibit widely diverging responses of the thermohaline circulation (THC). To investigate the mechanisms responsible for this variability, a regional Atlantic Ocean model driven with forcing ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Aerobic stability of heat and orchardgrass round-bale silage [PDF]
, 2004 In Arkansas, silage is typically stored as balage in long rows of round bales wrapped in plastic film. It is important to evaluate the aerobic stability of this fermented forage when it is exposed to air, especially during the winter months when most of ...

Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating
