Temperate wetlands are generally net retainers of sulphate (SO 4 -2 ). However, recent research indicates that some wetlands may export SO 4 -2 during drought conditions. In temperate wetlands, the susceptibility to drought will depend on wetland-str

Temperature variation of the coefficients of linear thermal expansion and optical length was measured with an interferometer using 632.8 nm wavelength light from a He‐Ne laser over the temperature range of 300–1300 K. The experiment was carried o

[1] Peatland drainage and peat extraction changes natural peatlands from a net carbon sink to that of a large net source due to increased respiration and the removal of carbon dioxide (CO2) fixing vegetation. Restoration of these altered peatland eco

Background: Nitrergic and prostanoid pathways have both been implicated in inflammatory processes. Objective: To investigate their respective contributions in a rat model of chronic arthritis. Methods: Male Wistar rats (n = 4–6/group) received eith

Nitric oxide and prostaglandins are both implicated in the pathogenesis of inflammatory conditions such as rheumatoid arthritis (RA). The hypothesis that simultaneous inhibition of nitric oxide synthase (NOS) and cyclooxygenase (COX) was more effecti

A simple laser interferometer has been utilized to measure the thermal expansion and optical‐length variation with temperature of highly reactive fluorides at high temperatures. The interferometer is a modification of the Jamin interferometer in wh

Thermal expansion and the optical length variation have been measured for a single crystal sodium β-alumina, along the c-axis. A laser interferometer has been used in the measurement. The measurements of the length and optical length variation do no

NMR measurements are reported here on a particular ${\mathrm{Ce}}^{3+}$-doped Ca${\mathrm{F}}_{2}$ crystal which, when analyzed in the light of existing relaxation theory, yield explicit expressions for the effective magnetic moment of the paramagnet

Divalent metal fluorides exhibit many anomalous properties as a result of their high anionic conductivity at temperatures characterized by a heat capacity peak at T c which occurs several hundred degrees below the melting temperature. Measurements of
