Measurements of trace metal species in situ in a softwater river, a hardwater lake, and a hardwater stream were compared to the equilibrium distribution of species calculated using two models, WHAM 6, incorporating humic ion binding model VI and visual MINTEQ incorporating NICA-Donnan. Diffusive gradients in thin films (DGT) and voltammetry at a gel(More)
Soaking in aqueous ammonia (SSA) and/or xylanase pretreatments were developed on wheat straw. Both pretreatments were conducted at high-solids conditions: 15% and 20%, respectively, for SSA and xylanase pretreatments. SSA pretreatment led to the solubilisation of 38%, 12% and 11% of acid insoluble lignin, xylan and glucan, respectively. In case of xylanase(More)
The myiasis-causing flies Cuterebra grisea (Coquillet) and Cuterebra fontinella (Clark) (Diptera: Oestridae) are normally parasites of mice, predominantly of the genus Peromyscus. The morphological similarities of these species and the existence of intermediate morphotypes bearing characters of both species make the identification of adults problematic;(More)
Several techniques for speciation analysis of Cu, Zn, Cd, Pb, and Ni are used in freshwater systems and compared with respect to their performance and to the metal species detected. The analytical techniques comprise the following: (i) diffusion gradients in thin-film gels (DGT); (ii) gel integrated microelectrodes combined to voltammetric in situ profiling(More)
This paper provides a review of literature on the effects of shift work on physical health, mental health and well-being. In Europe, 20% of the workforce is involved in irregular work schedules. Up to 70% of workers report problems, with increasing age, associated with more difficulties in adjusting to shift work. Epidemiologic studies on large populations(More)
The formation of a reversible adsorption complex between a dimer of N-acetyl-L-tyrosine [di-(N-acetyl-L-tyrosine), (NAT)2] and horseradish peroxidase (HRP) compound II (CII) was demonstrated using a kinetic approach. A specific KIIm value (0.58 mM) was deduced for this step from stopped-flow measurements. The dimerization of the dipeptide Gly-Tyr was(More)
Fatigue of voluntary muscular effort is a complex phenomenon, influenced by peripheral and central nervous system factors. Peripheral mechanisms of fatigue include impairment in neurotransmission and impulse propagation down the sarcolemna, dysfunction within the sarcoplasmic reticulum involving calcium release and uptake, impairment in the actin-myosin(More)
