The use of conservation drones in ecology and wildlife research

open access: yesJournal of Ecology and Environment, 2015
Conservation drones are remote-controlled devices capable of collecting information from difficult-to-access places while minimizing disturbance. Although drones are increasingly used in many research disciplines, their application to wildlife research

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

open access: yesAdvanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

What is the place of democracy in recreation ecology? [PDF]

open access: yes, 2008
What should be monitored and who decides has been debated for as long as recreation ecology has been with us. The early work on planning frameworks advocates consulting with visitors to determine what conditions are important to them and then derive ...

Toward Low‐Consumable Anodes: Process Simulation and Prospective Life Cycle Assessment of NiFe2O4‐NiO‐Ni‐Cu vs. Prebaked Anodes for Aluminum Production with use of Molten Salt Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐consumable nickel ferrite‐based anodes for the Hall–Héroult process are compared with conventional prebaked carbon anodes using thermodynamic simulation and prospective life cycle assessment under contrasting future electricity system pathways from 2025 to 2050.

Universal Ecology

open access: yesActa Neophilologica
This paper argues that Noam Chomsky’s universal grammar can be re-organized into a new concept for understanding climate change: universal ecology. Taking into account criticisms of Chomsky’s idea, we argue that the universal ecology approach focuses on

Political ecology and the epistemology of social justice [PDF]

open access: yes, 2007
Piers Blaikie’s writings on political ecology in the 1980s represented a turning point in the generation of environmental knowledge for social justice. His writings since the 1980s demonstrated a further transition in the identification of social justice

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

Distribution of anemones (Anthozoa: Actiniaria and Corallimorpharia) in the area of Santa Marta, Colombian Caribbean

open access: yesCiencias Marinas, 2002
This work characterizes and compares the community of anemones at two coralline areas in the Tayrona National Natural Park, in the Colombian Caribbean, and also relates the species that were found with some important characteristics of the reef ...
