Environmental regulation in Indonesia [PDF]

open access: yes, 1994
Since the early 1980s environmental regulation has received high priority in Indonesian policy making. Given Indonesia's dependence upon foreign donors for its economic program, external pressures inevitably played a significant role in stimulating this ...

Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

Raman Spectroscopic Identification of Oxide Phases in a Corroded MgO–Steel Composite Anode Used in Aluminum Molten Salt Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.

Sustaining Growth in a Resource-Based Economy: The Main Issues and the Specific Case of Russia [PDF]

open access: yes
This paper argues that the challenges posed by resource dependence, which include an increased vulnerability to external shocks, the risk of Dutch disease and the risk of development specific institutional pathologies, can be overcome, or at least very ...

The Effect on Woman of Economic Dependence [PDF]

open access: yesAmerican Journal of Sociology, 1909
The most famous description of a virtuous woman, and one accepted equally by both sexes, is that which has been attributed to Solomon: "Who can find a virtuous woman? for her price is far above rubies." The patriarchal estimate of virtue is thus evident.

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.

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 ...

RECENT CONTROVERSIES REGARDING THE DELAYS IN THE ECONOMIC DEVELOPMENT OF THE COUNTRIES FROM EASTERN EUROPE [PDF]

open access: yesAnalele Universităţii Constantin Brâncuşi din Târgu Jiu : Seria Economie, 2012
The European integration is the best way for the poor Eastern European societies to follow in order to progress. Gathering contacts with the Occident cannot push the former communist societies to the status of chronically backward peripheries.

Multifunctional Crushing and Piezoresistive Self‐Sensing in Conductive Epoxy/CNT‐Coated Polyetherimide TPMS Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports lightweight polyetherimide triply periodic minimal surfaces lattices coated with carbon nanotube‐reinforced epoxy that combine mechanical robustness with self‐sensing. The conformal coating enhances stiffness, strength and energy absorption while enabling reliable strain monitoring.
