Benz[a]anthracene induces aryl hydrocarbon hydroxylase activity in secondary fetal cell cultures derived from various inbred mouse strains. The maximally inducible level of hydroxylase activity from the C57BL/6N strain is 4 to 6 times higher than that from the DBA/ZN strain in cell cultures derived from the entire mouse fetus. There are no differences between C57BL/6N and DBA/2N cell cultures i...

here two atoms recombine thus forming a diatomic molecule that can be either chemisorbed or reflected in the gas-phase in a given internal energy state. Reactions (1)-(2) are very often the rate determining step of complex heterogeneous systems of interest in different branches of industrial and technological applications, as for example in the ammonia synthesis, hydrocarbon production, chemica...

Background:Several studies have reported the toxicological implications of inhalation of petroleum hydrocarbon fumes in animal models. But, there is certainly little or no documentation of the exposure to petroleum hydrocarbon fuel on oxidative stress levels in humans, unlike the pulmonary physiology. The present study was carried out to evaluate the effects of constituents of the hydrocarbon f...

A new method to generate chemical reaction network is proposed. The particularity of the method is that network generation and mechanism reduction are performed simultaneously using sampling techniques. Our method is tested for hydrocarbon thermal cracking. Results and theoretical arguments demonstrate that our method scales in polynomial time while other deterministic network generators scale ...

Liquids like gasoline comprise a mixture of hundreds of hydrocarbon components. Gas chromatography of these complex mixtures produces highly detailed chromatograms that are characteristic of a particular sample. Although many of the volatile components will be lost during the fire, sufficient less-volatile components may have been left in partially burned wood or other materials to enable the d...

Heavy oil is considered as a multipurpose complex mineral, and the processing of heavy oils “complex problem”, aimed both at increasing yield light fractions “transport” ability oil, extracting metals from asphaltene resinous fraction. The recovery (such vanadium, nickel, titanium, iron, etc.) was performed by cavitation extraction technology with use hydrocarbon solvents chemical extractants, ...

After introducing semantic anti-realism and the paradox of knowability, the paper offers a reconstruction of the anti-realist argument from understanding. The proposed reconstruction validates an unrestricted principle to the effect that truth requires the existence of a certain kind of “demonstration”. The paper shows that that principle fails to imply the problematic instances of the original...

This paper will concentrate on presenting a legal analysis of two of the main challenges to open source software: SCO’s litigation and software patents. The paper discusses the validity of such challenges, their possible impact to the future of open source software, and the possible legal defences used against them.

This article explores the way archival material has the potential to become a core component of activism, through an evaluation of an AHRC-funded collaborative research project on the histories and futures of local food in Liverpool. "Memories of Mr Seel's Garden: exploring past and future food systems in Liverpool" is a collaboration between four academics, two arts/heritage professionals and ...
