Pathogens are the most important factors inducing postharvest losses on citrus fruit. Experiments were conducted as a CRD with 4 replications on sweet lime (Citrus limetta) and Valencia orange (Citrus sinensis) in 2003 and 2004. Treatments were pure essential oils of clove and thyme and in 25% ethanol solution at concentrations of 0.1, 0.3 and 0.5% and imazalil (2 ml/l). Results indicated that ...
Undoubtedly, Tooth decay is still one of the most significant problems in human communities. Tooth decay is defined as a microbial disease that causes demineralization of hard tissues and degradation of organic components of teeth. Although there are various theories on etiology of dental caries, Miller’s acidogenic theory (1890) and Gottileb’s proteolitic theory (1933) have gained the most cre...
Utilizing boundary integral method (BIM), we investigate molecularspontaneous emission rate enhancement in the vicinity of plasmonic nanoparticles ofelliptical cross section. These types of nanoparticles can considerably enhance themolecule decay rate. The spontaneous emission rate can be modified by altering theaspect ratio of the elliptical nanoparticle, the background refractive index andnan...
We discuss the interpretation of Euclidean correlation functions at finite temperature (T ) and their relationship with the corresponding real-time Green’s functions. The soluble 2+1 dimensional Gross-Neveu model in the large-N limit is used throughout as a working example. First, the real-time bound state, identified as an elementary excitation at finite T , is solved. The bound state mass, th...
We measure the decay constant f(Ds+) using the D(s+)-->l+ nu channel, where the l+ designates either a mu+ or a tau+, when the tau+ -->pi+ nu. Using both measurements we find f(Ds+)=274+/-13+/-7 MeV. Combining with our previous determination of f(D+), we compute the ratio f(Ds+)/f(D+)=1.23+/-0.11+/-0.04. We compare with theoretical estimates.
the influence of initial moisture content on wood decay at different levels of atmospheric oxygen concentration was studied. three fungi, coriolus versicolor (c. versicolor) a white rot, coniophora puteana (c. puteana) a brown rot, and chaetomium globosum (c. globosum) a soft rot, were chosen. the mycelia of the fungi were inoculated in to mini blocks of fagus sylvatica (beech) and pinus sy...
s We study finite size effects of the d=3 XY model in terms of the chiral perturbation theory. We calculate by Monte Carlo simulations physical quantities which are, to order of (1/L), uniquely determined only by two low energy constants. They are the magnetization and the helicity modulus (or the Goldstone boson decay constant) in infinite volume. We also pay a special attention to the region ...
Literary texts are the product of individual unconscious psyche and collective consciousness. In Iranian mythology, Fereydoun and Zahhak are symbols of good and evil. This research is an attempt to demonstrate aspects of growth and decay according to Erich Fromm’s theories. It aims at finding aspects of growth (love of life, love of humanity, freedom from the archetypal Mother) and contra...
background: there have been numerous researches on elastomeric ligatures, but clinical conditions in different stages of treatment are not exactly similar to laboratory conditions. the aim of this in vitro study was to simulate clinical conditions and evaluate the effect of three stretching patterns on the amount of force, tensile strength (ts) and extension to ts of the elastomers during 8 wee...
