Seismic activity in the greater New York City area is concentrated along several northeast-trending faults of which the Ramapo fault appears to be the most active. Three nuclear power plants at Indian Point, New York, are situated close to the Ramapo fault. For a reactor site in use for 40 years, the probability that the site will experience an intensity equal to or in excess of the design (safe shutdown) earthquake is estimated to be about 5 to 11 percent. 相似文献

A technique to take sequential tissue biopsy samples in multiparous, periparturient ewes from the abomasal mucosa is described, developed in parallel in Scotland and New Zealand. Samples were extracted via abomasal cannulae inserted into the wall of the abomasum and exteriorised through dorso-ventral laparotomy. Animals recovered quickly post-surgery, and tolerated the cannula and sampling without any adverse signs of pain or discomfort. The technique was deployed in two pilot studies to investigate the sequential mucosal inflammatory cell responses in well-defined parasitological models, during the periparturient relaxation of immunity in ewes infected with gastrointestinal nematodes and subjected to different feeding treatments. One experiment (Moredun Research Institute, Scotland) involved the infection of twin-bearing ewes with Teladorsagia circumcincta L3 either before, or after lambing. By feeding ewes with different levels of protein supplementation, preliminary data on the impact of nutrition on the eosinophil, mucosal mast cell and globule leucocyte responses during this period were investigated. A similar study was also performed at Lincoln University, New Zealand, to investigate these cell responses in sheep fed relatively high or low protein diets during pregnancy, and infected with a combined immunisation regime of T. circumcincta and Trichostrongylus colubriformis L3. These studies confirmed the phenomenon termed the periparturient relaxation in immunity (PPRI) where a transitory increase in faecal egg counts is observed during late pregnancy and lactation, and this effect was exacerbated during protein undernutrition. Although the number of animals was low in each experiment and the cell responses variable, the results together suggest a reduction in the number of mucosal mast cells and globule leucocyte during the PPRI when protein supply was restricted. The present paper thus describes a successful technique to monitor ovine mucosal cell populations during local immune responses in normal and pregnant sheep. It is envisaged that this technique will be a powerful adjunct to investigations into mucosal immune mechanisms and disease pathogenesis, and will be employed to confirm the influence of dietary protein on the local inflammatory cell responses during the PPRI. 相似文献

A case of peripheral arterial tumor embolization in a cat is described. The cat presented with signs of aortic thromboembolism, including decreased peripheral pulse quality, pallor, and coolness of the distal limbs, as well as proprioceptive deficits. Thoracic radiographs revealed a cavitary lung mass; echocardiography was unremarkable. Cytologic evaluation of aspirates of the mass suggested malignancy. The left hindlimb was amputated, and histopathology confirmed embolization of an adenocarcinoma. Although rare, peripheral arterial tumor embolization should be considered as a differential in cats presenting with signs of thromboembolic disease. 相似文献

We present a framework for results‐based management (RBM) of commercial fisheries. The core idea of RBM is to reduce micromanagement by delegating management responsibility to resource users. The RBM framework represents an industrial organization approach to co‐management and comprises three defining processes, conducted by three independent “agents”: (i) an “authority” defines specific and measurable and achievable objectives (outcome targets, OTs) for the utilization of fisheries resources, (ii) resource user organizations (termed “operators”) take responsibility for achieving these OTs and provide documentation that (iii) allows independent “auditors” to evaluate the achievement of OTs. Using incentive mechanisms, notably deregulation, RBM grants operators the flexibility to develop and implement innovative and cost‐effective ways to achieve OTs. The feasibility of implementing RBM in five European fisheries was investigated in cooperation with relevant stakeholders through artificial planning processes and computer simulations. The operators involved were enthusiastic, and new management plans were drafted based on the framework. These included socioeconomic OTs in addition to traditional stock objectives, encompassing an ecosystem approach. Several issues are in need of further research to consolidate the approach and prepare the ground for practical implementation, including: the specification of the legal and regulatory framework required to underpin RBM, details of transitional arrangements when shifting towards RBM (including cost‐sharing) and the development of necessary organizational capacity for operators. Initially, we therefore envisage the framework being applied to high‐value single‐species fisheries, with a limited number of participants, which are adequately represented by a competent organization. 相似文献
