This work examines the e}ectiveness of the zero!angle cavities created by curved contact with a ~at surface in promoting vapor embryo capture\ low temperature boiling incipience\ and reduction or elimination of the incipience temperature overshoot with highly wetting liquids[ Using FC!61 as a test liquid\ both single and multiple spherical point contacts on a ~at heater in both horizontal and v...

Physical CHEMISTRY INTRODUCTION The basis for any design and simulation of chemical and environmental systems is a reliable set of physical and chemical properties of reactants. Since it is not always possible to find experimental values in the literature as well as measurement is expensive and time consuming or sometimes even difficult or impossible, estimation methods are generally of great v...

In this article, at first, a quantitative structure–property relationship (QSPR) model for estimation of the normal boiling point of liquid amines is developed. QSPR study based multiple linear regression was applied to predict the boiling points of primary, secondary and tertiary amines. The geometry of all amines was optimized by the semi-empirical method AM1 and used to calculate different t...

Boiling is the most common method of disinfecting water in the home and the benchmark against which other point-of-use water treatment is measured. In a six-week study in peri-urban Zambia, we assessed the microbiological effectiveness and potential cost of boiling among 49 households without a water connection who reported "always" or "almost always" boiling their water before drinking it. Sou...

background: antibiotic residue in food is a major concern from a health point of view. post-slaughter and pre-consumption processing such as cooking could affect residue. objectives: the purpose of this study is to survey the effect of boiling and microwave on tilmicosin in chicken. methods: chicken samples containing different tilmicosin amounts cooked in boiling water and in the microwave. af...
