Abraham model L solute descriptors have been determined for 149 additional C11 to C42 monomethylated and polymethylated alkanes based on published Kovat’s retention indices upon gas–liquid chromatographic measurements. The calculated descriptors, in combination with previously correlations, can be used predict a number of very important chemical thermodynamic properties including partition coef...
BACKGROUND Leukemia is cancer of the blood or bone marrow, characterized by an unusual increase in white blood cells. It is the sixth most common malignancy in the country in both males and females. The aim of this study was to document some epidemiological features of leukemia in the Northwest of Iran. METHODS The study subjects (n=669, including 377 males and 292 females) comprised all leuk...
In Arabidopsis thaliana, acyl-CoA-binding proteins (ACBPs) are encoded by a family of six genes (ACBP1 to ACBP6), and are essential for diverse cellular activities. Recent investigations suggest that the membrane-anchored ACBPs are involved in oxygen sensing by sequestration of group VII ethylene-responsive factors under normoxia. Here, we demonstrate the involvement of Arabidopsis ACBP3 in hyp...
Fusarium head blight (FHB) is an important disease of wheat and causes significant economic and yield losses. The principal pathogen associated with FHB in Manitoba is Gibberella zeae (Schwein.) Petch (anamorph = Fusarium graminearum Schwabe). Trichoderma harzianum Rifai is a well-known biocontrol agent of many plant pathogens. The extracts from 11 T. harzianum isolates and cellfree filtrates w...
Disagreement in Partners’ Reports of Financial Difficulty We use unique data in which both partners report about household finances to demonstrate that there is often disagreement about whether the household has experienced financial difficulty in the past year. Four alternative explanations for this disagreement are tested using the data. The results indicate that disagreement may be related t...
The dichotomous choice contingent valuation has been one of the most popular method to estimate Willingness-To-Pay (WTP) for nonmarket goods, such as environmental resources. Standard estimation procedures rely upon fully parametric assumptions on the model. This paper provides a new semiparametric estimation of the WTP distribution, which consists of three steps: In the first step, a finite-di...
This Working Paper should not be reported as representing the views of the IMF. The views expressed in this Working Paper are those of the author(s) and do not necessarily represent those of the IMF or IMF policy.
