Volvocine algae constitute a green algal lineage comprising unicellular Chlamydomonas, four-celled Tetrabaena, eight to 32-celled Gonium, and others up to Volvox spp., which consist of up to 50,000 cells. These algae proliferate by multiple fissions with cellular growth up to several fold in size and subsequent successive cell divisions. Chlamydomonas reinhardtii cells produce two to 32 daughte...

By Dawson F. D. Turner, M.D., F.R.C.P., Physician in Charge of Radium Department, Royal Infirmary, Edinburgh A male, aged 65, was recommended to me by Professor Alexis Thomson for radium treatment in June 1911. He was suffering from a recurrent small-celled lymphosarcoma, which was inoperable. The first operation was performed on 21st August 1909. The tumour was then situated in the axilla, and...

It would be an astonishing experience for an environmental microbiologist of 1985 to be teleported straight into 2015! Few things have remained the same in this dynamic research field, and our understanding of the abundance, diversity and activities of microorganisms on the planet Earth has been thoroughly revamped. Research technologies that were unimaginable in 1985 are producing data of unpr...

A computational methodology is proposed to describe the fluid transport in compressed opencelled metallic foams. Various unit-cell foam geometries are numerically deformed under uniaxial loads using a finite element method. An algorithm is developed and implemented to deform the fluid domain mesh inside the unit-cell foam based on the deformed solid unit-cell geometry. Direct simulations of the...

Early achievements in proteomics were qualitative, typified by the identification of very small quantities of proteins. However, as the subject has developed, there has been a pressure to develop approaches to define the amounts of each protein--whether in a relative or an absolute sense. A further dimension to quantitative proteomics embeds the behavior of each protein in terms of its turnover...
