Cell number. protein. and phorbol myristate acetate (PMA)-induced H202 production were measured in cultured human peripheral blood monocytes for six days after exposure to varying doses of ‘y-radiation. Both the number of adherent cells and the protein per dish decreased with increasing radiation doses. The dose of radiation decreasing the number of adherent cells by 37% on days 4 and 6 postirr...

In documenting biological responses to climate change, the Intergovernmental Panel on Climate Change has used phenology studies from many parts of the world, but data from the high latitudes of North America are missing. In the present article, we evaluate climate trends and the corresponding changes in sequential bloom times for seven plant species in the central parklands of Alberta, Canada (...

By chance, a Schmidt plate (+ H α filter) was taken on 6 March 1979, 2.6 days after the famous soft gamma-ray burst that took place on 5 March. Another four plates were exposed through UVBR filters four to six days after the event. N49 – the plerionic supernova remnant presumably related to the soft gamma ray repeater – and the surrounding area have been examined, on the basis comparison with a...

Multifrequency VLA and OVRO observations of the radio outburst of Cygnus X-3 in September 2001 are presented, illustrating the evolution of the spectrum of the source over a period of six days. An estimate of the magnetic field in the emitting region is made from the spectral turnover and possible explanations for the spectral evolution are suggested.

The instability behaviour of several supported liquid membranes (SLMs) has been studied for a system in which nitrate ions are removed from an aqueous feed phase and concentrated in a stripping phase. The composition of the aqueous phases and of the membrane liquid has been determined after the aqueous phases had flowed parallel to the membranes for a period of six days. From the experimental d...

A single solution protocol has been widely used for the fluorimetric determination of H2O2 in natural waters by its bleaching of the fluorescing scopoletin in the presence of the enzyme horseradish peroxidase (HRP). In this protocol, the reaction between scopoletin and H2O2 in the sample and the subsequent internal additions, and the measurements of the fluorescence are all carried out at a sin...

This is a rare syndrome, characterised by an acute, life-threatening, non-inflammatory encephalopathy and fatty degeneration of the liver with minimal or no clinical signs of liver involvement. In classic Reye's syndrome, there is a severe but self-limiting disturbance of mitochondrial structure and associated enzymatic disturbances usually lasting about six days. This is accompanied by an inte...

Differences in driving behavior due to the presence of users familiar/unfamiliar with the road are commonly considered in both road design (guidelines for road design) and traffic engineering (calculation of the equivalent traffic flow). However, although considered, the matter is largely unexplored: there is a lack of theoretical foundations and data on determining the impact of route familiar...

The C-band radar instruments onboard the two-satellite GMES Sentinel-1 constellation provide global measurements with short revisit time (about six days) and medium spatial resolution (5 × 20 m), which are appropriate for watershed scale hydrological applications. This paper aims to explore the potential of Sentinel-1 for estimating surface soil moisture using a multi-temporal approach. To this...
