The impact of hydraulic fracturing on housing values in Weld County, Colorado: a hedonic analysis
… activity in the state. Results across both the semi-log OLS and semi-log spatial GLS model specifications are consistent. While the count of wells being hydraulically fractured within a half mile of a house has a negative effect on houses in Greeley and other towns, rural households are …

An Experimental Study of Turbulent Boundary Layers Subjected to High Free-stream Turbulence Effects
… with the LDV, it was also determined that the semi-log law of the wall is valid for high free-stream turbulence cases, but with different constants than the ones proposed by Coles, where the constants for the high free-stream cases may be dependent on the turbulence intensity. For the first …

The Determinants of Urban Land and Property Values: The Case of Rwanda
… Rwandan urban households. With the use of the semi-log form of the hedonic price model and the survey data, factors of urban properties are determined and quantitative estimates of the Willingness-to-pay for environmental amenities are determined. The analysis of the results show that residents …

Height premiums for seaside community condominiums : an empirical analysis
… throughout the height of a given building. A semi-log regression equation is employed to isolate the impact of vertical location on price, and as expected, price does increase with floor height. The regression results conclude that for oceanfront buildings, condominium prices (relative to …

High sensitivity DNA detection using gold nanoparticles and conducting polymers
… DNA mismatches and a high sensitivity. Semi-log plots of the pathogen DNA concentration vs. faradaic current were linear from 150 pM to 1 μM and pM concentrations could be detected without the need for molecular, e.g., PCR or NASBA, amplification. PEDOT films have been created by …

Deterministic chaos in Alcator C-Mod edge turbulence
… the characteristic slope of the data on a semi-log plot gives the full width of the underlying Lorentzian pulses, which give rise to the exponential power spectra due to the dynamics of deterministic chaos. Using a separate fitting routine, individual Lorentzian pulses in the reflectometer …

Measuring the gender-wage differential and discrimination in the Eritrean labour market
… are estimated, in which, the dependent variable (semi-log monthly wage) is a linear function of years of schooling, experience, experience squared, and hours worked, and dummy variables capturing, occupations, ethnicity, industry, employer, marital status, fighters (represents whether the …

Capacitive Touchscreen Sensors for the Measurement of Ions in Electrolytes
… capacitance. The touchscreen senses a tight semi-log correlation of its capacitance with the conductivity of electrolytes below 100 μS/cm. This correlation is dependent on anion concentration and nearly independent of the measured cations for a positive electrode. Furthermore, a new approach …

Finite element study of geosynthetic encased stone columns in sensitive soft clay
… soils are also curved (concave upwards) in the semi-log space. However, under high consolidation stress or upon large shearing, these soils re-gain the features of re-constituted soil. Ground improvement methods like stone columns were reported as not effective when installed in the sensitive …

Analysis of the Profitability of Conservation Agriculture for Participating Smallholder Maize Farmers in the Vhembe District of Limpopo Province
… smallholder farmers demand complementary technologies and supporting policies. In South Africa, the adoption efforts for conservation agriculture have been done without a consideration of the economic viability of maize production for smallholder farmers. This study aims to analyze the …
