Feasibility of using pyranometers for continuous estimation of ground cover fraction in table grape vineyards
PAR Vitis vinifera global solar radiation
2014/10/28
This paper evaluates the feasibility of using pyranometers for continuous estimation of ground cover fraction (GCF) at remote, unattended sites. Photographical techniques were used for measuring GCF (...
A method for estimation of enzymatic browning and its suppression in apple slices
apple slices reflectance browning oxalate sulphite
2008/11/26
A described method is based on diffuse light reflectance in the spectral region 400-720 nm for the examination of enzymatic browning of apple slices. In this method apples are sliced as directly dippe...

Finite element aided brittle fracture force estimation during two-dimensional soil cutting
soil fracture crack growth finite element method blade configuration soil cutting forces
2008/11/21
Short crack behaviour during the two-dimensional cutting of brittle agricultural soils is a non-symmetrical mixed mode crack loading problem. The inability to resolve this problem limited the brittle...
Estimation of genetic variability of yielding traits and physical properties of seedsof spring barley (Hordeum vulgare L.) mutants
hull-less barley geometric properties resistance to squashing mutants yield structure
2008/11/19
The material for performed studies comprised 19 hull-less barley mutants, their initial form 1N/86, as well as six hul- led forms – three fodder and three malting cultivars. In field trial the mutants...
