We report the spectroscopic changes of tetraphenylporphyrin carbon nanotube composites in a variety of chlorinated solvents such as chloroform, dichloroethane and dichlorobenzene as a result of sonication. Detailed data analysis suggests that protonation of the porphyrin core nitrogen atoms occurs as a result of sonodegradation of the solvent molecules. Extreme care must be taken when working w...

The effect of chronic exposure (35 days) to sub-lethal concentrations of copper (17-212 ppb) and zinc (41-525 ppb) on growth of Farfantepenaeus paulensis postlarvae 17 days old (PL(17)) was analysed. The effects of acute exposure of PL(17) to the same metal on food ingestion and oxygen consumption were also evaluated. Studies were performed using copper and zinc singly, and in a mixture of equi...

This paper describes patient characteristics, including Ebola viral load, associated with mortality in a Médecins Sans Frontières Ebola case management centre (CMC).Out of 780 admissions between June and October 2014, 525 (67%) were positive for Ebola with a known outcome. The crude mortality rate was 51% (270/525). Ebola viral load (whole-blood sample) data were available on 76% (397/525) of p...

Ferrites-bismuth ferrite is an intriguing option for medical diagnostic imaging device due to its magnetoelectric and enhanced near-infrared fluorescent properties. However, the embedded XFO nanoparticles are randomly located on the BFO membranes, making implementation in devices difficult. To overcome this, we present a facile bio-approach to produce XFe2O4-BiFeO3 (XFO-BFO) (X = Cr, Mn, Co, or...

The complex formation and a liquid-liquid extraction in the cobalt(II) 4-(2thiazolylazo)resorcinol (TAR) 2,3,5-triphenyl-2H-tetrazolium chloride (TTC) water chloroform system was studied. The optimum extractionspectrophotometric conditions were found. The molar ratio of the reacting species was determined to be 1:2:1 (Co:TAR:TTC). The following equilibrium processes were quantitatively examined...

The objective of the present study was to clinically evaluate the sensitivity and dynamic range of three digital systems (Sens-A-Ray, CDR, Digora), digitized film and E-speed film. Five objects were submitted to three different kilovoltages and seven exposure times. In order to evaluate the relationship between exposure time and dosage, measurements were made in a dental x-ray unit with an ion ...
