Now available on Fast Track: Egg size and shape variation in Rufous Bush Chats (Cercotrichas galactotes) breeding in date palm plantations: hatching success increases with egg elongation

Posted on 23. April, 2018.

In oviparous taxa such as birds, clutch characteristics (e.g. egg size, egg mass and the number of eggs) can be considered as energetic investment in reproduction. In this paper, we study variation in the principal component indices of egg size and shape in Rufous Bush Chats (Cercotrichas galactotes) breeding in date palm plantations in the Al Amri Oasis, north Algeria, in 2008–2009 and 2011–2013.

Radiation effects on zeolite nanomaterials - some potential implications for cleaning liquid nuclear waste and for enhanced radioactive decontamination

Posted on 22. May, 2012.

Zeolites are used to help clean liquid wastes from nuclear power plants or to enhance radioactive decontamination. Progress in Reaction Kinetics and Mechanism presents results from the implantation of high energy positive muons in samples of cation-exchanged zeolite X  which give an insight into the long-term effects on zeolites of their exposure to ionising radiation.

Analyses of trace metals, peptide ligands of trace metals and mercury speciation in home prepared bread

Posted on 21. May, 2012.

How do fermentation and baking affect the structure, concentration and activity of chelating agents in home prepared bread? A study from the Czech Republic, reported in Chemical Speciation and Bioavailability, analyses alterations in the solubility and binding of trace elements that occur during the preparation of bread. Cereal grain proteins were found to be chelators of trace elements in the raw material. Some ligands of trace elements diminished during bread making, probably as the result of thermal denaturation.

Micro reactors: industrial results

Posted on 24. April, 2012.

Micro reactors and flow reactors have many advantages as tools in organic synthesis. A review in the April issue of Journal of Chemical Research describes how small reactor volumes enable reactions to be performed on an industrial scale more efficiently and safely than when using batch processes.

Sir William Ramsay and the Noble Gases

Posted on 24. April, 2012.

Sir William Ramsay was one of the world’s leading scientists at the end of the 19th century, and in a spectacular period of research between 1894 and 1898, he discovered five new elements. These were the noble gases, helium, neon, argon, krypton, and xenon; they added a whole new group to the Periodic Table of the elements, and provided the keystone to our understanding of the electronic structure of atoms, and the way those electrons bind the atoms together into molecules.
