The behavior of sorbic acid in model systems comprised of concentrated sugar solutions (water activity 0.94) at pH 3.5 and 4.5 was studied. Sorbic acid degraded appreciably as a function of time and temperature during storage and its destruction could be described by first-order kinetics. The rate constants of sorbic acid destruction were found to be related to composition of the sugar model sy...

Abstract. In this study we show how errors due to finite box size affect formation and destruction rate for haloes in cosmological N-body simulations. In an earlier study we gave an analytic prescription of finding the corrections in the mass function. Following the same approach, in this paper we give analytical expressions for corrections in the formation rate, destruction rate and the rate o...

The mitotic kinase Aurora A (Aur-A) is overexpressed in a high proportion of human tumors, often in the absence of gene amplification. In somatic cells, Aur-A protein levels fall following mitosis or upon overexpression of Cdh1, an activator of the ubiquitin ligase APC/C. Thus, mutations that reduce or block the rate of Aur-A destruction might also be expected to contribute to its oncogenic pot...

Through online optimization and control, vapor compression systems (VCSs) can effectively respond to disturbances, such as weather or varying loads that cannot be accounted for at the design stage, while simultaneously maximizing system efficiency. However, to do so requires a mathematical characterization of efficiency for the VCS. In particular, we would like to maximize the exergetic efficie...

the destruction of profit and its consequent liability has a crucial role in regulating legal and social relations. in contracts, like hire, sale and sharecropping and also in extra contractual liability such as destroying, usurpation and receiving, lawyers and jurists have partially argued about the subject and have tried to offer a legal and jurisprudent interpretation, in order to compensate...

kaiss al-kaiss**, zahra hakimzadeh*** exploring saadi’s literary character to gain insight of overall picture of arab literature in his work is not entirely realized when dealing only with his persian accomplishments, it is necessary to study his accomplishments in arabic poems alongside with his persian works to succeed in such venture. saadi has a variety of purpose in his usage of arabic lan...
