The impact of fire frequency on selected soil physical properties in a semi-arid savannah Thornveld

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
The use of fire in rangeland management is standard practice, but the impact of fire frequency on soil physical properties is still not properly understood. In this study, the effect of fire frequency on selected physical properties was studied in a long-

Establishing an analogue population for the most distant galaxies

open access: yes, 2014
Lyman break analogues (LBAs) are local galaxies selected to match a more distant (usually z~3) galaxy population in luminosity, UV-spectral slope and physical characteristics, and so provide an accessible laboratory for exploring their properties ...

Diffusion‐Weighted Imaging for the Evaluation of the Sacroiliac Joint in Pediatric Patients

open access: yesArthritis Care &Research, EarlyView.
Objective Maturational signal in the sacroiliac joint (SIJ) of skeletally immature youth is often misinterpreted as inflammation. Diagnostic tools that improve specificity are greatly needed. Apparent diffusion coefficient (ADC) values from diffusion‐weighted imaging (DWI), when used with standard imaging, may enhance diagnostic accuracy.

Local Analogs for High-redshift Galaxies: Resembling the Physical Conditions of the Interstellar Medium in High-redshift Galaxies

open access: yes, 2016
We present a sample of local analogs for high-redshift galaxies selected in the Sloan Digital Sky Survey (SDSS). The physical conditions of the interstellar medium (ISM) in these local analogs resemble those in high-redshift galaxies.

Soil hydro-physical Environment as Influenced by Different Biochar Amendments

open access: yesInternational Journal of Bio-Resource and Stress Management, 2017
Biochar acts as a soil conditioner, improving soil physical properties, nutrient use efficiency and thereby increasing plant growth. An experiment was conducted at ICAR-National Organic Farming Research Institute during the year 2016−17 in order to ...
