A iatrogenia é uma alteração patológica provocada no doente que pode ocorrer nas várias fases do acto médico. Nos EUA é considerada a quarta causa de morte, mas em Portugal as referências na literatura são escassas e a sua incidência é desconhecida. Ainda que diferente de erro médico, continua tema tabu para os profissionais de saúde. Apresenta-se o caso clínico de iatrogenia relacional, diagnóstica e terapêuti...
A double-sheeted double many-body expansion potential energy surface is reported for the coupled 12A‘/22A‘ states of HN2 by fitting about 6000 ab initio energies. All crossing seams are described to their full extent on the basis of converged results. The lowest adiabatic sheet is fitted with a rmsd of 0.8 kcal mol-1 with respect to the calculated energies up to 100 kcal mol-1 above the absolute minimum, and th...
A detailed ab initio multireference configuration interaction calculation with a standard aug-cc-pVTZ basis set is reported for the 12A‘ and 22A‘ states of the title system. The aim is to establish the dissociation scheme of all channels, while revealing the 22A‘/32A‘ seam of conical intersections consistent with the crossings in the diatomic fragments. An ab initio mapping of linear NNH and T-shaped and linear...
The ClO3 many-body expansion potential energy surface of Farantos and Murrell (Int J Quantum Chem 1978, 14, 659) has been modified along the minimum energy path for the reaction O + OClO rarr ClO + O2 such as to conform with the available kinetics data. The dynamics of the title reaction is also studied for temperatures of relevance in stratospheric chemistry. Two mechanisms for ClO + O2 formation are identifie...
This paper proposes a new transient recorder (TR)-time digitizer (TD) hybrid system to be used to pull out higher performance of presently used techniques for measuring the collimated flux and the spectrum of the neutron emission from fusion plasmas of either deuterium or deuterium-tritium, as well as to apply to new neutron measuring techniques, with demanding specific requirements in plasma physics. This syst...
