Myrtaceae is one of the chemically most variable and most significant essential oil yielding plant families. Despite an abundance of chemical information, very little work has focussed on the biochemistry of terpene production in these plants. We describe 70 unique partial terpene synthase transcripts and eight full-length cDNA clones from 21 myrtaceous species, and compare phylogenetic relatio...

This paper estimates a dynamic model of the world oil market and tests whether OPEC countries colluded and whether non-OPEC countries behaved oligopolistically over the period 1970-2004. The model generates estimates of the shadow price of the resource with minimal functional form assumptions. Results support oligopolistic behavior among non-OPEC producers and collusion among OPEC producers exc...

In order to improve pyrolysis chromatographic analysis of materials that release polar functional groups e.g. carboxylic acids, a simple and rapid methylation method based on TDUpyrolysis/GC-MS in the presence of tetramethylammonium hydroxide (TMAH) was developed. Linseed oil was selected as test material because of its high triglyceride content comprising both saturated and unsaturated fatty a...

Olive oil, the main source of fat in the Mediterranean diet, is a functional food which besides having a high level of monounsaturated fatty acid contains several minor components with biological properties. For some olive oil minor components, such as the antioxidant phenolic compounds, a large body of studies, mainly experimental or in animal models, have been performed. Randomized, controlle...

------ARSTRACT-----Corn germ protein isolate (CGP[) was partially hydrolyzed with tryp~ sin and pepsin and succinylated at three levels. Various functional and electrophoretic properties of the native and modified protein were determined. Water absorption and foaming properties of COPT were improved by panial hydrolysis with trypsin: emulsifying capacity and nitrogen solubility were reduced~ oi...

One remaining issue of CO2 processes are problems in connection with the lubrication oil. The objective of this project is to prove the feasibility of a small oil free semi hermetic piston type CO2-compressor for supercritical heat pump applications with large temperature spans. These processes involve high pressures like 35 bar suction pressure and 80 to 150 bar delivery pressure. A functional...

Biocrude (fast pyrolysis oil from wood) was hydrotreated to minimize the negative aspects of this fuel. The instability of the oil was reduced by reaction of the most unstable functional groups. Concurrently, the oxygenated component of the oil was also reduced, resulting in an improved energy density. Changes in the physical handling properties were also modified. All of this change was accomp...
