ABSTRACT The use of supplementary cementitious materials (SCMs) is a major way to reduce the carbon footprint of concrete. Mechanochemical activation (MCA) can be used to activate inert materials that can then be used as SCMs. In this study, the effect of MCA using a planetary ball mill was investigated for 16 materials, ranging from natural occurring ...

Net Buyers, Net Sellers, and Agricultural Landowner Support for Agricultural Zoning [PDF]
Agricultural zoning and land use restrictions are long-standing approaches for controlling non-agricultural development. Agricultural landowners may contest agricultural zoning if they expect zoning to reduce land prices on restricted land.

ABSTRACT Experimental study and thermodynamic modeling of the phase equilibria in the FeO–FeO1.5–SbO1.5–SbO2.5–SiO2 system in air and 1 atm oxygen, and in equilibrium with Sb/Sb–Ag metal has been undertaken. Experimental data at 575°C–1600°C were obtained using high‐temperature equilibration of mixtures in sealed silica ampoules, Fe3O4 basket/MgO ...

ABSTRACT The phase equilibria of the “Cu2O”–FeO–Fe2O3–Al2O3–SiO2 system in equilibrium with metal were studied as part of the investigation of the 20‐component PbO–ZnO–Cu2O–FeO–Fe2O3–CaO–SiO2–Al2O3–MgO–S–(As, Sn, Sb, Bi, Ag, Au, Ni, Cr, Co, and Na as minor elements) slag/matte/metal/speiss/gas system in support of the operation/development of existing ...

ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Metamorphic Reactivity Influences Amphibole Creep Behaviour
ABSTRACT The rheological behaviour of solid‐solution minerals may play an important role in determining how metamorphic crust accommodates deformation. Whether or not a mineral's deformation is diffusion or dislocation‐mediated depends on a range of extrinsic variables such as stress, strain rate and temperature, as well as intrinsic variables such as ...

Open Space and Urban Sprawl: The Effects of Zoning and Forest Conservation Regulations in Maryland [PDF]
Rapid urbanization enhances the desirability of policies for preserving open space but policies intended to preserve open space may extend the urban boundary and create leapfrog development.

Abstract The light element distribution in planetary cores and the processes driving core evolution in rocky planets are poorly understood. Magmatic iron meteorites are samples from the cores of ancient embryonic planetesimals and therefore provide a window into the processes governing core evolution. We performed high precision oxygen isotope analyses

Lot Size, Zoning, and Household Preferences: Impediments to Smart Growth? [PDF]
The paper explores a number of issues related to lot size and urban density. First, trends in single-family residential lot size over the past 35 years are examined in eight counties in the state of Maryland.

Abstract We report the discovery of the second (Al,Cu)‐alloy–bearing micrometeorite, FB‐A2, recovered from Mount Gariglione (southern Italy), representing the sixth such occurrence worldwide. Although chondritic in nature, FB‐A2 differs markedly from previously described microspherules.
