Middle Archaic Complex of Northwest Arkansas [PDF]
, 1969 After the end of the Wisconsin glacial there occurred an interval called the Neothermal in the southwestern portion of the United States. The Neothermal is comprised of three consecutive tempera-ture intervals: the Anathermal, Altithermal, and ...

Local ecosystem feedbacks and critical transitions in the climate [PDF]
, 2009 Global and regional climate models, such as those used in IPCC assessments, are the best tools available for climate predictions. Such models typically account for large-scale land-atmosphere feedbacks.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Dating climatic change in hot deserts using desert varnish on meteorite finds [PDF]
Earth and Planetary Science Letters, 2003 A thin coating of desert varnish occurs on Forrest 009 and Nurina 004, both equilibrated ordinary chondrite (L6) finds from the Nullarbor Plain, Australia. This finely laminated deposit is chemically and petrographically comparable to the varnish found on terrestrial rocks.

Advanced Functional Materials, EarlyView.Copper catalysts introduced with different non‐metallic elements regulating the coordination number of Cu are prepared by magnetron sputtering. Reducing the Cu coordination number enhances C─C coupling and boosts C2+ product selectivity, by lowering the energy barrier for the *CO → *CHO conversion step. The optimized Si‐doped Cu catalyst achieves a C2+
