A fast, convenient and sensitive method of capillary zone electrophoresis (CZE) and indirect UV detection was proposed for the determination of 16 amino acids. p-Aminobenzoic acid (PAB) was selected as a background electrolyte (BGE). An isolated cell included a BGE buffer part and an electrode buffer one, which were jointed with a glass frit. The isolated cell can prevent PAB from the electrode...

Using a slight modification of the framework in Bramson [7] and Williams [52], we prove heavy traffic limit theorems for six families of multiclass queueing networks. The first three families are single station systems operating under first-in first-out (FIFO), generalized headof-the-line proportional processor sharing (GHLPPS) and static buffer priority (SBP) service disciplines. The next two ...

In the healthy human being, the blood has a pH value of 7.4. Even slight deviations from this value may lead to severe disturbances in metabolism which may even be life-threatening. It is for this reason that the body`s extensive buffer systems ensure that the blood pH is maintained between the very narrow limits of 7.37 and 7.43. These buffer systems bind and neutralize the additional protons ...

The usefulness of including a buffer between fishery management targets and limits has frequently been acknowledged. This paper shows how decision theory can be used to set both targets and limits. Decision theory uses expected utility as the objective function to be maximized, and thus requires specification of a utility function. The utility function assumed here exhibits constant absolute ri...

Contrary to the view that embryos and larvae are the most fragile stages of life, development is stable under real-world conditions. Early cleavage embryos are prepared for environmental vagaries by having high levels of cellular defenses already present in the egg before fertilization. Later in development, adaptive responses to the environment either buffer stress or produce alternative devel...

A simple, accurate and precise RP-HPLC method was developed for simultaneous estimation of Rosuvastatin Bisoprolol fumarate in bulk formulation. Separation achieved using C18 column Methanol: Phosphate buffer (pH 3.5) at a ratio 45:55% V/V, flow rate maintained 1.0 ml. min 245 nm used as determination wavelength. System suitability parameters shows values within specified limits. Developed vali...

A high performance liquid chromatographic method with ultra violet detection for simultaneous analysis of six benzodiazepines (BZDs) (chlordiazepoxide, diazepam, clonazepam, midazolam , flurazpam and lorazepam) has been developed for forensic screening of adulterated non-alcoholic drinks. Samples were analyzed after a simple procedure for preparation using pH adjustment and filtering. Isocratic...
