Introduction: The Mediterranean corn borer (MCB), Sesamia nonagrioides, is a major pest of maize, Zea mays, in Mediterranean countries, inflicting significant kernel yield losses. For that reason, it necessary to know the genetic mechanisms that regulate the agronomic and resistance traits. A quantitative trait loci (QTL) mapping study for yield, resistance against MCB attack, and other relevan...

Background and Aims: Newcastle disease virus (NDV) is an avian paramyxovirus (A-PMV 1) and one of the major pathogens in poultries. Vaccination is intended to control the disease, nevertheless this virus is a growing threat to the poultry industry. So, early detection of the virus can prevent the spread of illness and avoid huge economic losses. Towards this goal, in this research, we develop...

The aim of this paper is to investigate adhesion property between nano-layered filler and the polymer matrix using a combination of experimental and micromechanical models as well as the changes in yield strength and stiffness of a layered silicate-filled epoxy nanocomposite. The results indicate that addition of intercalated layered silicate particles increased Young’s modulus and yield streng...

Fresh water supply and its security encounter a high level of fluctuating variability under global climate changes. To address these concerns in catchment water management, a good understanding of land use/cover impacts on the hydrological cycle affecting water supply is crucial. The objective of this study is to define a model to investigate the impact of existing land use/cover on water yield...

The factors affecting the yield of high-mass molecules by matrix-assisted ultraviolet laser volatilization are examined in a simple model. The key material factors appear to be a low heat of sublimation, subcritical concentration of the guest molecules and a high irradiance input in a short time compared to the sublimation induction period. The model is homogeneous in that the energy density is...
