RESUMO

^{180m}Ta is a rare nuclear isomer whose decay has never been observed. Its remarkably long lifetime surpasses the half-lives of all other known ß and electron capture decays due to the large K-spin differences and small energy differences between the isomeric and lower-energy states. Detecting its decay presents a significant experimental challenge but could shed light on neutrino-induced nucleosynthesis mechanisms, the nature of dark matter, and K-spin violation. For this study, we repurposed the Majorana Demonstrator, an experimental search for the neutrinoless double-beta decay of ^{76}Ge using an array of high-purity germanium detectors, to search for the decay of ^{180m}Ta. More than 17 kg, the largest amount of tantalum metal ever used for such a search, was installed within the ultralow-background detector array. In this Letter, we present results from the first year of Ta data taking and provide an updated limit for the ^{180m}Ta half-life on the different decay channels. With new limits up to 1.5×10^{19} yr, we improved existing limits by 1-2 orders of magnitude which are the most sensitive searches for a single ß and electron capture decay ever achieved. Over all channels, the decay can be excluded for T_{1/2}<0.29×10^{18} yr.

RESUMO

This review begins with an examination of the notion of quality in the industrial setting, its definition and the steps taken to achieve quality assurance. The review then considers what is meant by quality in the field of health, and in particular for orthopedic devices dispensed in a community pharmacy. Special attention is given to dispensing standard orthopedic devices; five aspects are considered: organization, personal competence, products, services, and relationship with the patient. The first aspect, organization, involves the selling area, stocks, different sizes and sale prices, and the introduction of new devices. Dispensing involves, reception and physical examination of the patient, information delivery, decision-making on the choice of an orthesis, measurement, trial and application, as well as complementary advice and completion of the patient's file. Quality is measured in terms of patient needs.

RESUMO

"In this article I examine the effects of state autonomy, regime type, and the capacity of governments on the formulation and implementation of social development and family planning policies which in turn affect patterns of fertility behavior in poor third world countries." The author concludes that the state has to become actively involved if the rate of population growth is to be brought under control.
