Through this study, the ability of a modified Peng-Robinson (MPR) equation of state in predicting the surface tension of n-alkanes based on the density functional theory approach was investigated and compared with other studies. The interfacial layer thickness and the density profile were calculated simultaneously at different temperatures from triple point to near critical point using the modi...

Background: Tension and migraine headaches are the most prevalent types of headaches. Some emotional and psychological factors are associated with these headaches. Objectives: To elucidate the nature of individual differences in emotion regulation and repetitive negative thinking among patients with tension headaches and migraine and compare it with normal subjects.

On the basis of data from 2000 to 2010, we investigated the separate effects of the uptake of forest certification and the usage of recycled paper on imports of paper and paperboard into Germany and the United States. Using panel data methods and based on a conventional Armington trade model, we find that the effects of two main forest certification schemes—the Programme for Endorsement of Fore...

Since the pioneering work of Krugman (1980) economists try to quantify the welfare gains from an increase in traded variety. The seminal work of Feenstra (1994) and its application to the U.S. of Broda and Weinstein (2006) allowed this quantification for the first time using highly disaggregated trade data. In this paper it is argued that size and openness of a country are important factors in ...

Models with monopolistic competition and constant elasticity of substitution (CES) preferences have become a mainstay of theoretical and empirical work in international trade. However, the standard model yields contrafactual predictions on the number of varieties, prices and output per variety that are traded. In particular the model predicts a rate of variety growth that is faster than that ob...

abstract: introduction & objective: teaching human anatomy, at any level, relies not only on the expertise of a tutor but also on the availability and use of good teaching aids. plastination specimens have a unique position as a teaching aid to exhibit accurate anatomical structures and are easy to be stored and handled by students. the aim of this study was to assess the comparative use of pol...

The idea of unarticulated constituents is used in several different ways in the philosophy of mind and the philosophy of language. My purpose here is to clarify these uses and thereby illustrate that there is considerable tension between them. More specifically, I will argue that if one endorses the original arguments in support of unarticulated constituents of the contents of thoughts and utte...
