Three language constructs appropriate for the design and pro­ gramming of distributed systems are described. The team abstracts repeated interprocess activities and isolates processes to the context where they are needed. The interaction provides multiparty synchronization and communi­ cation. The superimposition defines modules that augment existing teams. Partial correctness proof rules and c...

7-Chloro-6,8-dinitro­quinazolin-4(3H)-one acetic acid monosolvate

In the title compound, C(8)H(3)ClN(4)O(5)·C(2)H(4)O(2), both the nitro groups are close to perpendicular [dihedral angles = 67.62 (15) and 86.73 (12)°] to the almost planar quinazoline unit [r.m.s. deviation = 0.014Å]. In the crystal, both the quinazoline and acetic acid mol-ecules form inversion dimers linked by pairs of N-H⋯O and O-H⋯O hydrogen bonds, respectively. R(2) (2)(8) loops arise in ...

Spectrophotometry of theophylline-7-acetic acid and theophylline.

A spectrophotometric assay procedure is described for individually measuring theophylline-7-acetic acid and theophylline in 2.0 ml of serum. Absorbance is a linear function of concentration over a range of 0.5-40 mg/liter for theophylline-7-acetic acid and 0.5-40 mg/liter for theophylline. No endogenous or exogenous compounds were found that interfere with theophylline-7-acetic acid determinati...

Theophylline-7-acetic acid: lack of absorption and therapeutic effectiveness.

A double-blind cross-over trial was conducted to evaluate the effectiveness of oral theophylline-7-acetic acid (T7AA) in 13 asthmatic patients. Pulmonary function tests showed no difference between T7AA and placebo. No T7AA or theophylline was found in the sera of these patients or of healthy volunteers who took T7AA tablets or syrup.
