Puerto del Pendulo, doubtful sound: la visita de la expedición Malaspina a Nueva Zelanda en busca de la verdadera forma de la tierra / Puerto del Pendulo, doubtful sound: the Malaspina expedition's visit to New Zealand in quest of the true figure of the earth

The Malaspina expedition was assigned the task of conducting a series of experiments using the pendulum to measure the strength of gravity at different locations during the course of its voyage.The immediate objective was to establish the length of a pendulum beating at seconds at latitude 45º as the basic unit of a new universal system of measures. Although the new unit, the metre, was eventually established on a different principle, the gravity experiments carried out by the expedition resulted in useful geodesic information and incidentally led to the first charting of Doubtful Soundin New Zealand (AU)

La expedición Malaspina tuvo por misión realizar una serie de experimentos utilizando un péndulo para medir la fuerza de la gravedad en los diferentes lugares recorridos durante el viaje. El objetivo inmediato consistió en establecer la longitud de un péndulo oscilando durante unos segundos a una latitud de 45º como unidad básica de un nuevo sistema métrico universal. Aunque la nueva unidad, el metro, fue finalmente establecida por otro principio diferente, los experimentos que llevó a cabo la expedición sobre la gravedad proporcionaron una información geodésica muy útil y por casualidad dieron lugar al primer trazado de mapa de Doubtful Sound, en Nueva Zelanda (AU)

Emergency medicine expeditions to the developing world: the Loma Linda University experience in Papua New Guinea.

Emergency physicians (EPs) are increasingly participating in international medicine in regions that are chronically medically underserved. In August 1994, a ten-member emergency medicine team from the Loma Linda University School of Medicine staffed a 70-bed bush hospital in the primitive highlands of Papua New Guinea, providing both outpatient and inpatient medical care. Typhoid fever, malaria, polio, and numerous other infectious diseases were encountered. Rampant local tribal warfare resulted in regular penetrating injuries from arrows, spears, and machetes. The expedition was judged highly successful, in that 1) substantial medical service was provided to tribespeople accustomed to minimal care, 2) education was provided to local health care providers, and 3) team participants became adept at managing medical conditions uncommon in industrialized societies, and gained valuable ethical and utilitarian perspectives regarding health care delivery in underserved areas. In this article the objectives, organization, and experiences of the team members are described. This information may encourage other EPs to participate in medical expeditions to the developing world, and to provide general principles to assist in their organization and implementation.
