The reduction behavior of pelletized and pre-oxidized ilmenite is investigated in H2-H2O atmospheres containing between 0 7% H2O at temperatures 983 1183 K (710 910 °C). mechanism occurs two stages wherein the rapid trivalent to divalent iron cations followed by slower metallization iron. Both temperature gas composition are critical achieving high reaction rates; within range conditions studie...

Pertussis is a highly contagious disease caused by the Gram negative aerobic coccobacillus, Bordetella pertussis. It may present with severe symptoms and complications in infants and can pose a diagnostic challenge. This is a vaccine preventable illness covered by the Irish Childhood Immunisation Schedule. In 2011, a retrospective review was conducted of the records of infants, under six months...

Hereditary spherocytosis is a congenital haemolytic anaemia due to defect in spectrin-a RBC membrane protein and is transmitted as autosomal dominant. Due to this defect there is presence of characteristic spherical cell in peripheral blood smear and osmotic fragility is increased. Haemolytic anaemia, reticulocytosis, jaundice and splenomegaly are present. This article reports a case of a 9 yea...

Acinetobacter baumannii is a Gram-negative coccobacillus found primarily in hospital settings that has recently emerged as a source of hospital-acquired infections. A. baumannii expresses a variety of virulence factors, including type IV pili, bacterial extracellular appendages often essential for attachment to host cells. Here, we report the high resolution structures of the major pilin subuni...

Results of a polyphasic taxonomic study on an unknown Gram-negative, facultatively anaerobic, coccobacillus-shaped organism isolated from an infected human gall bladder are presented. Phenotypic and molecular taxonomic studies revealed the organism to be close to, but distinct from, organisms designated CDC (Centers for Disease Control and Prevention) group DF-3. The unknown bacterium was readi...

Contamination of heavy metals represents one of the most pressing threats to water and soil resources as well as human health. Phytoremediation can be potentially used to remediate metal-contaminated sites. This study evaluated the potential of 36plants (17species) growing on a contaminated site in North Florida. Plants and the associated soil samples were collected and analyzed for total metal...
