New type of asymmetric fission in proton-rich nuclei.

A very exotic process of ß-delayed fission of 180Tl is studied in detail by using resonant laser ionization with subsequent mass separation at ISOLDE (CERN). In contrast to common expectations, the fission-fragment mass distribution of the post-ß-decay daughter nucleus 180Hg (N/Z=1.25) is asymmetric. This asymmetry is more surprising since a mass-symmetric split of this extremely neutron-deficient nucleus would lead to two 90Zr fragments, with magic N=50 and semimagic Z=40. This is a new type of asymmetric fission, not caused by large shell effects related to fragment magic proton and neutron numbers, as observed in the actinide region. The newly measured branching ratio for ß-delayed fission of 180Tl is 3.6(7) × 10(-3)%, approximately 2 orders of magnitude larger than in an earlier study.

Información escrita entregada por los equipos de soporte de Cuidados Paliativos a pacientes, familia y personal de atención primaria de salud en las visitas en domicilio / No disponible

Objetivo: conocer y comparar los distintos documentos que entregan los Equipos de Soporte de Cuidados Paliativos (ESCP) a los pacientes, familia y profesionales de Atención Primaria de Salud responsables del seguimiento de los pacientes incluidos en el Programa Regional de Cuidados Paliativos de Extremadura, en las visitas domiciliarias. Pretendemos averiguar si existen diferencias en las distintas áreas de salud y, de existir, si tienen relación con las características de dichas áreas y de sus ESCP. Material y método: el material de estudio son los documentos entregados por los ESCP y los datos demográficos y de recursos sanitarios de las áreas de salud de Extremadura, sin olvidar el personal de los ESCP. En cuanto a la metodología se realiza estudio estadístico descriptivo e inferencial. Resultados: cinco son los documentos entregados en domicilio: informe médico y de enfermería (lo entrega el 50% de los ESCP), hoja de tratamiento (100%), documento de presentación (75%), consejos impresos (75%) y hoja de registro de medicación subcutánea continua (12,5%). En cuanto al análisis comparativo solo encontramos diferencias estadísticamente significativas en el empleo de informe médico y de enfermería por los ESCP con menor presión asistencial (p = 0,0135). Conclusiones: existen pequeñas diferencias en el número, contenido y formato de los documentos que entregan los ESCP en domicilio. Cada ESCP ha encontrando lo que facilita la atención a los pacientes, familias y personal de Atención Primaria. Las diferencias son enriquecedoras, deben de verse como algo que respetar y de donde aprender

Objective: to know the different documents given by Palliative Care Support Teams in Extremadura’s Regional Palliative Care Program to patients, family members, and primary care professionals during home visits. We attempt to know any differences between health areas, and their relation to demographic characteristics and Palliative Care Support Teams. Material and method: the study material includes all documents given by Palliative Care Support Teams, and the demography and resources of health areas in Extremadura, including Palliative Care Support Team staff. A descriptive and comparative statistical study is made. Results: five documents are given during home visits: medical and nursing report (50%), treatment (100%), presentation document (75%), advice (75%), and registry for continuous subcutaneous medication (12.5%). Differences are statistically significant in the use of medical and nursing reports by Palliative Care Support Teams (p = 0.0135). Conclusions: differences in number, content, and format between the written documents given by Palliative Care Support Teams at home are small. The different Palliative Care Support Teams use the most appropriate written documents in their health areas. Differences are good, we must respect and learn from differences
