Precise Nucleosynthesis Limits on Neutrino Masses [PDF]

open access: yes, 1996
A computation of nucleosynthesis bounds on the masses of long-lived Dirac and Majorana neutrinos is reviewed. In particular an explicit treatment of the ``differential heating'' of the $\nue$ and $\bnue$ ensembles due to the residual out-of-equilibrium ...

The MINOS experiment: results and prospects [PDF]

open access: yes, 2013
The MINOS experiment has used the world's most powerful neutrino beam to make precision neutrino oscillation measurements. By observing the disappearance of muon neutrinos, MINOS has made the world's most precise measurement of the larger neutrino mass ...

Balancing Production and Environmental Goals in Pasture‐Based Dairy Systems: A Longitudinal Case Study of Transition in a High Performing New Zealand Farm

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Production and environmental outputs of intensive pasture‐based dairy systems must be rebalanced to reduce overall environmental footprint. This analysis documents the tactical management changes that enabled Lincoln University Dairy Farm (LUDF) to transition from high nitrogen (N) inputs (345 kg N fertiliser/ha/year) to a lower N input strategy (167 ...

Potential to Improve Nitrogen Fertilizer Use Efficiency and Mitigate Pollution in Tropical Pastures Grazed by Sheep

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
We hypothesize that increasing N application rates will affect N use efficiency (NUE) for lambs grazing warm‐season annual grasses. We evaluated the effect of N fertilizer application rates (50, 100, 200, and 400 kg N/ha) on forage pearl millet (Pennisetum glaucum (L.) R.) and animal responses: N balance and NUE per animal and per area basis.

Nitrogen rates shaping rice yield and groundwater nitrate in the Jamuna River basin of north central Bangladesh

open access: yesJSFA reports, Volume 6, Issue 4, Page 121-130, April 2026.
Abstract Background Understanding how varying nitrogen fertilizer rates influence both rice productivity and groundwater nitrate contamination is critical for ensuring sustainable crop production and environmental protection in the Jamuna River Basin of north‐central Bangladesh.

Soil and crop responses following application of biosolids-derived organomineral fertilisers to ryegrass (Lolium perenne L.) grown in pots [PDF]

open access: yes, 2014
Biosolids-derived organomineral fertilisers (OMF) were produced using a novel technique reported in earlier studies. This technique enables addition of N and potash to biosolids granules to form a balanced NPK fertiliser.

Nitrogen dynamics and nitrogen use efficiency of spring cereals under Finnish growing conditions [PDF]

open access: yes, 2007
Nitrogen (N) is one of the main inputs in cereal cultivation and as more than half of the arable land in Finland is used for cereal production, N has contributed substantially to agricultural pollution through fertilizer leaching and runoff.

Nitrogen use efficiency in cereals production under Mediterranean conditions [PDF]

open access: yes, 2014
Nitrogen use efficiency (NUE) for cereal production in Mediterranean regions is generally low due to N losses over winter and difficulties in calculating the optimum N level for a particular season, given that it depends on the existing rainfall pattern.

Logarithmic electroweak corrections to e+ e- -> nue anti-nue W+ W-

open access: yes, 2006
We consider W-boson scattering at high-energy e+ e- colliders and study one-loop logarithmic electroweak corrections within the Standard Model assuming a light Higgs boson. We present explicit analytical results for W+ W- -> W+ W-. Using the equivalent vector-boson approximation, we have implemented these corrections into a Monte Carlo program for ...
