in this study, different derivative spectrophotometric methods are proposed for the simultaneous determination of chlorpheniramine maleate (cp), phenylephrine hcl (pe) and phenylpropanolamine hcl (pp) in their ternary mixtures and in pharmaceutical dosage forms. spectra of single component and ternary mixtures of various concentrations and combinations from zero- to fourth-derivation were obtai...

We consider a particular global optimization problem whose special structure permits the use of a decomposition algorithm optimizing globally only in search spaces of lower dimension. Roughly speaking, this problem involves the optimization of a weighted average of objective function values, subject to the same weighted average of constraints, where the weights are to be determined. We present ...
Postponement has been a major keyword in the description and the study of demographic trends observed in developed countries during the last decades. With few exceptions, during the recent decades demographic events such as those leading to the formation of new households and families have occurred later and later in the lives of women and men. Although considerable heterogeneity exists both be...
We have performed a search for the angular-momentum forbidden decay K+→π+γ with the E787 detector at BNL. No events were observed in the π+ kinematic region around 227 MeV/c. An upper limit on the branching ratio for the decay is determined to be 3.6× 10−7 at 90% confidence level. Typeset using REVTEX
آسفالت ماده ای ترکیبی است که از مخلوط کردن شن و ماسه و قیر ساخته می شود و در ساخت جاده، باند فرودگاه و ... به کار می رود. یک جاده تازه ساخت در اوایل دارای خواص فیزیکی و مکانیکی عالی است، اما به مرور زمان این خواص را از دست می دهد. علاوه بر اثرات دمایی که باعث خرابی آسفالت می شوند، افزایش بار ترافیک و فشار زیاد وسایل نقلیه نیز عامل خرابی زودرس آسفالت می باشند. شکلهای اصلی خرابی آسفالت شامل شیارش...
In this article, the effects of different foam production times and temperatures on the mechanical, physical, and structural properties of polypropylene (PP) foam has been investigated. The microcellular PP foams were carried out using supercritical carbon dioxide (sc-CO2) as a physical foaming agent in a batch process. The samples were placed in a pressure vessel and were saturated ...
