Twenty-three general practices in the UK randomised 229 paediatric patients (aged 1-12 years, body weight8 kg) with clinical evidence suggestive of streptococcal tonsillitis and/or pharyngitis in this physician-blind study. Patients received either c

The heat capacity of the perovskite high‐TC superconductor YBa2Cu3O7−δ was measured from 5.3 to 350 K in an adiabatic calorimetric cryostat. A break in the heat‐capacity curve, associated with the critical temperature for superconductivity was

NH4PF6 undergoes two transitions at ambient pressure on cooling: Fm (3) over barm-C2/c and an isosymmetric C2/c-C2/c transition. Isosymmetric transitions must be discontinuous. However, while this transition displays a latent heat, there is little si

The heat capacity Cp of the salt nitrosyl tetrafluoroborate, NOBF4, has been measured from 10 to 304 K, and that of potassium tetrafluoroborate from 9 to 295 K. The heat capacity–temperature curve of the nitrosyl compound has a λ‐type anomaly wi

The heat capacity C p of ammonium chloride, ammonium bromide and the mixed crystal NH 4 Br 0.55 Cl 0.45 has been analysed, for temperatures in the range 0-500 K, on the assumption that can be expressed as the sum of the terms ( C p — C v ), C (lat.

The heat capacities of KReO4 and NH4ReO4 from 8 to 304 K have been measured. The data show no obvious order–disorder phase transition but the curve for NH4ReO4 has a broad bump extending from about 100 to 250 K with a maximum around 200 K. This bum

The thermodynamic equilibria involved in the catalytic steam reformation of methanol to produce hydrogen have been examined over the ranges of pressure 101–3040 kPa, temperature 400–700K and water to methanol feed ratio 1.5–0.67. Four models ha
