The estimation of productivity and quality of sainfoin forage

open access: yesЗерновое хозяйство России, 2020
In the arid south ofRussiasainfoin is one of the key perennial legume forage grasses. It has a number of economic and biological traits and properties, such as anything goes approach to soil cultivation, drought tolerance, early maturity, stability of ...

Renormalizabilty of TH Heavy Quark Effective Theory

open access: yes, 1993
We show that the Heavy Quark Effective Theory is renormalizable perturbatively. We also show that there exist renormalization schemes in which the infinite quark mass limit of any QCD Green function is exactly given by the corresponding Green function of

Probing the N = 32 shell closure below the magic proton number Z = 20: Mass measurements of the exotic isotopes 52,53K [PDF]

open access: yes, 2015
The recently confirmed neutron-shell closure at N = 32 has been investigated for the first time below the magic proton number Z = 20 with mass measurements of the exotic isotopes 52,53K, the latter being the shortest-lived nuclide investigated at the ...

ASSESSMENT OF SAINFOIN BREEDING MATERIAL ON PRODUCTIVITY

open access: yesЗерновое хозяйство России, 2018
If we choose sainfoin during growing it can increase productivity of the crop. For the purpose we should take the varieties which are well adapted to the local weather-climatic conditions.  In the years 2011-2014 we studied hybrid populations of sainfoin,

Extended HI Rotation Curve and Mass Distribution of M31

open access: yes, 2006
New HI observations of Messier 31 (M31) obtained with the Effelsberg and Green Bank 100-m telescopes make it possible to measure the rotation curve of that galaxy out to ~35 kpc.

The Schwinger Mass in the Massive Schwinger Model [PDF]

open access: yes, 1995
We derive a systematic procedure to compute Green functions for the massive Schwinger model via a perturbation expansion in the fermion mass. The known exact solution of the massless Schwinger model is used as a starting point. We compute the corrections
