Actitudes de los profesionales de Enfermería hacia el enfermo crónico y terminal

Hemos estudiado una muestra (n=IOO) de profesionales de enfermería de las provincias de Alicante y Valencia, analizando las actitudes, según el modelo de Ajzen y Fishbein, con respecto a dos grupos de enfermos: crónicos y terminales. En general las actitudes de estos profesionales son bastante positivas en ambos casos y en todos su s componentes; aunque encontramos como hecho más destacado una tendencia actitudinal más baja significativamente hacia el enfermo terminal en sus componentes afectivo y comportamental.

Copper-Impregnated Magnetite as a Heterogeneous Catalyst for the Homocoupling of Terminal Alkynes

Copper-impregnated magnetite is a versatile heterogeneous catalytic system for the synthesis of 1,3-diynes by the homocoupling of terminal alkynes. This catalyst does not require the use of pressurized oxygen as the oxidant and it does not need a solvent or harsh conditions to give the expected products. Moreover, the catalyst can be removed from the reaction medium simply by using a magnet. The reaction occurs at the lowest copper loading reported for any heterogeneous catalyst.

Microwave-assisted palladium-catalyzed highly regio- and stereoselective head to head dimerization of terminal aryl alkynes in water

A highly regio- and stereoselective oxime palladacycle/imidazolinium-catalyzed head to head dimerization of terminal aryl alkynes in water is presented. The reaction, which is carried out at 130 °C under microwave irradiation in the presence of 1,3-bis-(2,6-diisopropylphenyl)imidazolinium chloride as ligand, triethylamine as base, and TBAB as surfactant, allows the synthesis of (E)-1,4-enynes as single stereoisomers in good isolated yields.
