A fairly sensitive, simple and rapid spectrophotometric method for the determination of some beta-lactam antibiotics, namely ampicillin (Amp), amoxycillin (Amox), 6-aminopenicillanic acid (6APA), cloxacillin (Clox), dicloxacillin (Diclox) and flucloxacillin sodium (Fluclox) in bulk samples and in pharmaceutical dosage forms is described. The proposed method involves the use of pyrocatechol viol...

In recent decades, cereal agriculture across main producing areas in Spain has progressively adopted direct sowing, associated with an increased use of herbicides pre-sowing. Weedy species from genus Avena have been observed after the application glyphosate wheat. Here, fatua (two accessions), byzantina and sterilis subsp. sterilis, one accession each, were taxonomically characterized by a biom...

In nuclear fusion magnetic confinement devices, equilibrium calculations for realistic systems are necessarily based on numerical solutions. In the present work, we describe some of the latest updates to the code FLOW [L. Guazzotto, R. Betti, J. Manickam and S. Kaye, Phys. of Plasmas 11, 604 (2004)] and give some applications. In this work we apply the code to both tokamak and Reverse Field Pin...

In the present work, the effects of flow on tokamak equilibria are investigated, focusing in particular on the effects of poloidal flows. It is shown that discountinuous transonic equilibria with a pedestal structure can be obtained for relatively low values of the poloidal velocity. Equilibria with poloidal flow of the order of the poloidal Alfvén speed are shown to develop inverted Shafranov ...

The temperature and salt dependencies of absorption by liquid water (H2O) and heavy water (D2O) were determined using a hyperspectral absorption and attenuation meter (WET Labs, AC-S). Sodium chloride (NaCl) was used as a proxy for seawater salts. There was no significant temperature (PsiT) or salt (PsiS) dependency of absorption at wavelengths <550 nm. At wavelengths >550 nm, PsiT exhibited pe...

We use a 1-D numerical model to study the atmospheric photochemistry of oxygen, methane, and sulfur after the advent of oxygenic photosynthesis. We assume that mass-independent fractionation (MIF) of sulfur isotopes – characteristic of the Archean – was best preserved in sediments when insoluble elemental sulfur (S 8 ) was an important product of atmospheric photochemistry. Efficient S 8 produc...
