摘要:

Abstract—During the latter part of 1979, hundreds of thousands of Kampuchean refugees fled from all parts of their war‐and hunger‐ridden country to the Thai–Cambodian border, thousands perishing from hunger, disease and by stepping onto mine fields on their way. The majority of those who survived settled in several large villages straddling the border in relative security from the advancing Vietnamese army, receiving food and medical supplies from many international welfare organizations.Widespread public interest in the plight of these refugees arose in Israel after a television program late in October 1979, and a public campaign was initiated by Mr. Abie Nathan, an Israeli citizen. The ensuing large‐scale fund raising efforts resulted in the substantial sum of 1.2 million dollars, most of which originated from private donations. These contributions enabled the Israeli government to equip 5 medical teams and send them to Thailand, covering the last 2 months of 1979 and the first 4 months of 1980.The first medical team, consisting of 5 physicians and 4 medics started i t s work in the camp of SaKaeo in Thailand on 4th November 1979.This paper summarizes our experiences in this ref

摘要:

Abstract—Three earthquakes have been studied. These are the Thessaloniki earthquake of 20th June 1978 (Ms = 6.4, Normal faulting), the Tabase‐Golshan earthquake of 16th September 1978 (Ms = 7.7 Thrust faulting) and the Carlisle earth‐quake of 26th December 1979 (Mb = 5.0, Thrust faulting). The techniques employed to determine source parameters included field studies of SUP face deformation, fault breaks, locations of locally recorded aftershocks and teleseismic studies including joint hypocentral location, first motion methods and waveform modelling. It is clear that these techniques applied together provide more information than the same methods used separately.The moment of the Thessaloniki earthquake determined teleseismically (Force moment 5.2 times 1025dyne cm. Geometric moment 1.72 times 108m3) is an order of magnitude greater than that determined using field data (surface ruptures and aftershock depths) (Force moment 4.5 times 1024dyne cm. Geometric moment 0.16 times 108m3). It is concluded that for this earthquake the surface rupture only partly reflects the processes on the main rupture plane. This view i s supported by a distribution of aftershocks and damage which extends well outside the region of ground rupture. However, the surface breaks consistently have the same slip vector direction as the fault plane solutions suggesting that they are in this respect related to to the main faulting and are not superficial slumping. Both field studies and waveform studies suggest a low stress drop which may explain the relatively little damage and loss of life as a result of the Thessaloniki earthquake.In contrast, the teleseismic moment of the Tabas‐e‐Golshan earthquake (Force moment 4.4 times 1026dyne cm. Geometric moment 1.5 times 109m3) is similar t o that determined from field studies (Force moment 10.2 times 1026dyne cm. Geometric moment 3.4 times 109m3) and the damage and after‐shock distributions clearly relate to the surface faulting. It h a s also been observed that high aftershock activity appears beneath gaps in the surface rupture system.The Carlisle earthquake (Force moment 9 times 1023dyne cm. Geometric moment 3 times 106m3) produced no surface ruptures. However, dislocation model‐ling suggests that surface deformation will be visible on a first order levelling line which passes very close t o the epicentre. A well controlled fault plane solution, the first in the British Isles, derived from an aftershock study shows north‐south compression.All three studied earthquakes occurred along major faults which had been reactivated in geological times. The fault on which the Tabas‐e‐Golshan earthquake occurred could have been identified a s active from evidence of Quaternary motion and previous smaller earthquakes. However, there were no perceptible events in the 12 months preceeding the catastrophic earthquake. In both Thessaloniki and Carlisle, significant foreshocks did occur within 6 months prio

摘要:

Abstract—A brief report was presented on a new outbreak of leptospirosis among the population of Greater Recife in 1975 in the wake of the floods that struck the city and its survivors in July of that year. A total of 107 cases were recorded, of which 105 were identified by sero‐agglutination and 2 by hemoculture. Once again the serotype icterohaemorrhagiae was the predominant etiological agent, having been found in 55 cases, followed byballumin 18,grippotyphosain 9, andpyrogenesin 8 ca
