Voltammetric behavior and trace determination of lead at a mercury-free screen-printed carbon electrode (2000)
Journal Article

Abstract Screen-printed carbon electrodes (SPCEs), without chemical modification, have been investigated as disposable sensors for the measurement of trace levels of Pb. Cyclic voltammetry was employed to elucidate the electrochemical behavior of Pb...

Excision from tRNA genes of a large chromosomal region, carrying avrPphB, associated with race change in the bean pathogen, Pseudomonas syringae pv. phaseolicola (2000)
Journal Article

Pseudomonas syringae pv. phaseolicola (Pph) race 4 strain 1302A carries avirulence gene avrPphB. Strain RJ3, a sectoral variant from a 1302A culture, exhibited an extended host range in cultivars of bean and soybean resulting from the absence of avrP...

A study of the effects of acid on the polymerisation of pyrrole, on the oxidative polymerisation of pyrrole and on polypyrrole (2000)
Journal Article

The polymer products arising from the hydrochloric acid treatment of aqueous pyrrole were shown to have spectroscopic data consistent with alternating pyrrole and pyrrolidine units with varying degrees of ring opening of the pyrrole units. The acid c... Read More about A study of the effects of acid on the polymerisation of pyrrole, on the oxidative polymerisation of pyrrole and on polypyrrole.

The flight heights of chalcid wasps (Hymenoptera, Chalcidoidea) in a lowland Bornean rain forest: Fig wasps are the high fliers (2000)
Journal Article

Tropical rain forests are characterized by their rich plant diversity and highly diverse insect faunas containing mainly rare species. Phytophagous and parasitoid insects utilizing such fragmented resources often must travel considerable distances to...

Supernatants from leucocytes treated with melanin-concentrating hormone (MCH) and α-melanocyte stimulating hormone (α-MSH) have a stimulatory effect on rainbow trout (Oncorhynchus mykiss) phagocytes in vitro (2000)
Journal Article

Melanin-concentrating hormone (MCH) and α-melanocyte stimulating hormone (α-MSH) are widespread vertebrate neuropeptides. In teleost fish the peptides are involved in the hormonal control of skin pigmentation, but they have also been shown to modulat...

A direct regional scale estimate of transgene movement from genetically modified oilseed rape to its wild progenitors (2000)
Journal Article

One of the major environmental concerns over genetically modified (GM) crops relates to transgene movement into wild relatives. The pattern of hybridization ultimately affects the scale and rapidity of ecological change and the feasibility of contain...

A study of methods for evaluating the integrity of plate type heat exchangers used in the dairy industry (2000)
Journal Article

An overview of leak testing methods for heat exchangers is presented. The problems associated with the presence of residual liquid during testing were assessed as it was shown experimentally that complete drainage of plate type heat exchangers is ver...
