Reducing emissions is essential for minimizing the impact of soil fumigation on the environment. Water application to the soil surface (or water seal) has been demonstrated to reduce 1,3-dichloropropene (1,3-D) emissions in soil column tests. This study determined the effectiveness of water application to reduce emissions of 1,3-D and chloropicrin (CP) in comparison to other surface seals under...

In this explorative study we examine factors explaining individual choice of lifestyle. The empirical analysis of smoking, exercising and diet show that the mechanisms determining people’s lifestyle are complex. We argue that the economic models on the demand for health is a meaningful framework for analysing this issue, but that it needs some refinements. A suggestion for further analytical wo...

Highly cracked and isomerized archaeal lipids and bacterial lipids, structurally changed by thermal stress, are present in solvent extracts of 2,707- to 2,685-million-year-old (Ma) metasedimentary rocks from Timmins, ON, Canada. These lipids appear in conventional gas chromatograms as unresolved complex mixtures and include cyclic and acyclic biphytanes, C36-C39 derivatives of the biphytanes, a...

This paper discusses the issue of perceptions and their influence on economic processes focusing on corruption perception. The higher the perceived corruption in an organization is, the more probable it is that a person dealing with that organization would offer a bribe, thus supporting corruption. Since corruption perceptions are rarely based on actual experience, they might describe reality i...

The security of sensitive individual data is a subject of indisputable importance. One of the major threats to sensitive data arises when one can link sensitive information and publicly available data. In this paper we demonstrate that even if the sensitive data are never publicly released, the point estimates from the empirical model estimated from the combined public and sensitive data may le...

This paper analyses the effect of nine categories of news announcements on the quoting activity of individual FX dealers on the Euro/Dollar exchange rate from May to October 2001. We use the Double Autoregressive Conditional Poisson model (DACP), which is designed for time series of count data, which can be both underor overdispersed. We find that dealers’ quoting activity reacts differently to...

The Selective Laser Melting process was used to perform cobalt-based alloy coatings on a C35 steel substrate. relationships between interlayer times, iron dilution, crystalline structures, and micro-hardness were studied for different numbers of layers with an initial lased powder layer 50 µm thickness. Reducing the time increased temperature reached in melting bed promoted matter transport fro...

Abstract The experiments were conducted in the Laboratory of Tissue culture/Department Forestry/College Agriculture and Forestry/the University Mosul. To propagate three citrus rootstocks (Citrus aurantium L., Citrumelo swingle , Cariso 35 (C35))In vitro . During Initiation stage, single nodes planted on a solid MS medium supplemented with five concentrations BA (0, 1, 2, 3, 4 mg L -1 ). After ...

Joint Labour Supply Dynamics of Older Couples This paper studies the labour force participation dynamics of older couples in the United States. Longitudinal data from the five available waves of the Health and Retirement Study (HRS) is used to investigate if the dynamics introduced by considering both spouses’ behavior provide additional information in trying to fit observed participation seque...
