Since kodo millet is a self-pollinated plant, it essential to understand the factors that influence length of flowering period, pollination behaviour, and seed set in order improve breeding programme effectiveness yield stability while also boosting productivity. Kodo flowers remain closed because they are cleistogamous nature. They have tiny florets. Emasculation artificial hybridization chall...

One of the most important factors in determining the volume of trees is selection of appropriate form factor. In the present study, four different methods of form factor calculation were evaluated for two rapid growth species including Populus deltoides and Taxodium distichum. For this purpose, in each stand, 12 trees per 4 diameter class ranging from 10 to 45 cm in DBH were randomly selected a...

Deviations from the Standard Model (SM) expectations of the Lepton Universality (LU) breaking represent a powerful tool to probe New Physics (NP) effects. In the present document, we focus on R K = Γ(K e2)/Γ(K µ2), stressing the importance of R K measurements with an accuracy at the % level to probe lepton-flavor violating effects arising in Supersymmetric (SUSY) theories. Finally, we also revi...

In recent years a new potential symmetry of fundamental particle physics has been investigated — discrete quark-lepton symmetry. When this symmetry is implemented, however, it often leads to either of the unrealistic predictions m u = m e or m d = m e. This paper considers two possible ways models based on m d = m e can be made realistic.

1550-7998=20 The recent measurements of the solar neutrino mixing angle sol and the Cabibbo mixing angle C reveal a surprising relation, sol C ’ 4 , which has been interpreted as an evidence for quark-lepton unification. We show in realizations of quark-lepton unification that the PMNS mixing matrix can be decomposed into a CKM-like matrix and maximal mixing matrices. We explore a possibility t...

The recent experimental measurements of the solar neutrino mixing angle θsol and the Cabibbo mixing angle θC reveal a surprising relation, θsol + θC ≃ 4 . We review that while this empirical relation has been interpreted as a support of the idea of grand unification, it may be merely accidental in the sense that reproducing the relation at a low energy in the framework of grand unification may ...

Fermion compositeness and other new physics can be signalled by the presence of a strong four-fermion contact interaction. Here we present a study of leqq and !&?e’ contact interactions using the reactions: et!? --f e’+e’-, b&, CC at future e+elinear colliders with fi = 0.5 5 TeV and p+pcolliders with 4 = 0.5,4 TeV. We find that very large compositeness scales can be probed at these machines an...

Small-scale patches (locations of 50 cm × 50 cm at a feeding station level) in a bahia grass ( Paspalum notatum ) pasture under cattle grazing were investigated in terms of herbage mass, quality and utilisation during a grazing season (May–November), to characterise the quantityquality relationship of patches and relate this to spatially heterogeneous grazing by animals. Nitrogen concentration ...
