Estimation of the average aromatic cluster size based on solid-state NMR measurement of coal
(Japan Institute of Energy, 1999)
Measurements of solid-state NMR of eight Argonne Premium Coal Samples were conducted to estimate the average aromatic cluster size in these coals. Firstly, the carbon distribution was obtained from SPE/MAS 13C-NMR. Secondary, ...
Dry deposition fluxes and mass size distributions of Pb, Cu, and Zn measured in Southern Lake Michigan during AEOLOS
(American Chemical Society, 1998)
As part of the Atmospheric Exchange Over Lakes and Oceans Study (AEOLOS) the dry deposition fluxes and atmospheric size distributions (ASDs) of anthropogenic metals were measured over the southern basin of Lake Michigan. ...
Progress depends on unbalance and disorder
(IEEE, 1997)
Technology is a state of progress which depends on unbalanced structures of human functions and relations. Technology was once the vital element of mankind to survive in nature. But today, technology has reached a perfection ...
Determination of technetium in sea-water using ion exchange and inductively coupled plasma mass spectrometry with ultrasonic nebulisation†
(Royal Society of Chemistry, 1998-09)
An enrichment–separation scheme employing a strong-base type anion-exchange resin was developed for the determination of99Tc in sea-water by inductively coupled plasma mass spectrometry utilising ultrasonic nebulisation ...
Prolactin receptor gene expression in rat splenocytes and thymocytes from birth to adulthood
(Elsevier, 1996-03)
In vivo and in vitro studies have indicated that the anterior pituitary hormone prolactin (PRL) is an immunoregulator and functions in the development of the neonatal immune system. In this study, prolactin receptor (PRL-R) ...
Prolactin receptor gene expression in rat splenocytes and thymocytes during oestrous cycle, pregnancy and lactation
(Wiley-Blackwell, 1997-05)
Much evidence suggests that prolactin (PRL) has an immunoregulatory function. Part of this evidence is that the receptors for PRL are present on lymphocytes. Probably the effects of PRL on cells of the immune system depend ...
Determination of plutonium in seawater using co-precipitation and inductively coupled plasma mass spectrometry with ultrasonic nebulisation1
(Elsevier, 1998-07-06)
A flow injection–inductively coupled plasma–mass spectrometric (FI–ICP–MS) procedure, utilising ultrasonic nebulisation with membrane desolvation (USN/MD), has been developed for the determination of plutonium (Pu) in ...
A novel sorbent tube for ambient hydrogen sulfide determination
(Elsevier, 1998-11)
A novel tubular device has been developed for hydrogen sulfide determination in air. Several substrates such as commercial silica gel and alumina TLC plates, silica gel powder, alumina, CaSO4, CaCO3, BaSO4, MgO, chalk, ...
Higgs field as the gauge field corresponding to parity in the usual space-time
(World Scientific Publishing, 1998-02)
We find that the local character of field theory requires the parity degree of freedom of the fields to be considered as an additional discrete fifth dimension which is an artifact emerging due to the local description of ...
Adsorption of PEO/PPO triblock co-polymers and wetting of coal
(Elsevier, 1999-01)
The adsorption characteristics of PEO/PPO/PEO triblock co-polymers on coal were investigated using surface tension and contact angle measurements. Although these surfactants have been widely used as wetting agents, it was ...
