The linear σ model with broken U3×U3 is compared with data on the lightest scalar and pseudoscalar mesons. When 5 of the 6 parameters are fixed by the pseudoscalar masses and decay constants one finds that, already at the tree level, a reasonable description for the 4 scalar masses, mixing and up to 8 trilinear couplings of lightest scalars, taken as a0(980), f0(980), σ(≈ 500) and K 0 (1430). T...

We demonstrate a novel assay for purification of RNA (16S rRNA) from whole human blood infected with Pseudomonas Putida (P. Putida). This assay is unique in that the extraction chemistry provides a method which both lyses bacteria cells and protects RNA from degradation when isolating from matrices rich with ribonuclease (RNase) (such as blood). The method can also be integrated with on-chip RN...

We enhance the recently proposed Optimized-orbital Quasi-Variational Coupled Cluster Doubles (OQVCCD) method for the calculation of ground-state molecular electronic structure by augmenting it with the standard perturbative (T) correction for the effects of connected triple excitations. We demonstrate the OQVCCD(T) ansatz to be outstandingly robust and accurate in the description of the breakin...

Thawed, frozen ;mixed oxalated' blood for haematology or citrated blood from the blood bank may be used as a precision control, maintaining reliability and accuracy, for periods of one to two years from a single batch of control material. Blood haemoglobin determinations using the cyanmethaemoglobin method and the Coleman Jr. spectrophotometer can be done routinely with a day-to-day variability...

Catha edulis (khat) is a plant grown commonly in the horn of Africa. The leaves of khat are chewed by the people for its stimulant action. Its young buds and tender leaves are chewed to attain a state of euphoria and stimulation. Khat is an evergreen shrub, which is cultivated as a bush or small tree. The leaves have an aromatic odor. The taste is astringent and slightly sweet. The plant is see...

CLINICAL CHEMISTRY, Vol. 27, No. 12, 1981 2071 displacement during head rotation and vaginal examinations, and amniotic fluid contamination may explain in vivo differences. Biological factors, reflecting blood and tissue fluid, might also affect the measurements, producing real differences in tissue and blood pH values. At present, because of these differences, in vivo continuous measurement of...
