Given the current rate of human population growth, mass breeding insects for feed and food is in full industrial development, as a more efficient effective alternative to conventional livestock production animal protein. In these industries, insect excreta (frass) represents one main outputs process, being up 40 times greater than biomass, which why its use organic fertilizer replace agrochemic...

The connection between the scales of SU(2) × U(1) gauge symmetry breaking and supersymmetry breaking is didactically displayed in the framework of a T.O.Y. (Theory Overestimating Yukawas) model, a version of the (M + 1)SSM (supersymmetric extension of the standard model with a gauge singlet) in which the relevant parameters are determined in the fixed point regime. Some conspicuous features of ...

We consider the problem of supersymmetry and electroweak breaking in a 5d theory compactified on an S 1 /Z 2 orbifold, where the extra dimension may be large or small. We consider the case of a supersymmetry breaking 4d brane located at one of the orbifold fixed points with the Standard Model gauge sector, third family and Higgs fields in the 5d bulk, and the first two families on a parallel 4d...

We show that a Nambu−Jona-Lasinio type four-fermion coupling at the z = 3 Lifshitz-like fixed point in 3 + 1 dimensions is asymptotically free and generates a mass scale dynamically. This result is nonperturbative in the limit of a large number of fermion species. The theory is ultra-violet complete and at low energies exhibits Lorentz invariance. Many of our results generalize to z = d in odd ...

Abstract In the present study we examined effect of presence wheat bugs ( Eurygaster spp. and Aelia spp.) on mortality, progeny production infestation patterns three stored product insects, Trogoderma granarium Everts, Sitophilus oryzae (L.) Rhyzopertha dominica (F.). The bioassays were carried out under laboratory conditions (25 ± 1 °C, 60 5% relative humidity (r.h.) continuous darkness), 20 a...

We analyse the general features of the Higgs and supersymmetric particle spectrum associated with the infrared fixed point solution of the top quark mass in the Minimal Supersymmetric Standard Model. We consider the constraints on the mass parameters, which are derived from the condition of a proper radiative electroweak symmetry breaking in the low and moderate tanβ regime. In the case of univ...

The supersymmetric SO(10) GUT with t–b–τ Yukawa coupling unification has problems with correct electroweak symmetry breaking, experimental constraints (especially b → sγ) and neutralino abundance, if the scalar masses are universal at the GUT scale. We point out that non-universality of the scalar masses at the GUT scale generated both by (1) renormalization group running from the Planck scale ...

We summarize recent results on the nonperturbative quark-gluon interaction in Landau gauge QCD. Our analytical analysis of the infrared behaviour of the quark-gluon vertex reveals infrared singularities, which lead to an infrared divergent running coupling and a linear rising quark-antiquark potential when chiral symmetry is broken. In the chirally symmetric case we find an infrared fixed point...

Through two loop effective potential we demonstrate that the MS scheme of dimensional regularization and Jackiw's prescription in cutoff regularization allow for the dynamical breaking solution in massless λφ 4 theory, while the Coleman-Weinberg prescription does not. The beta function of the broken phase is negative, like in the one loop effective potential, but the UV fixed point is not zero,...
