A total of 111 samples (43 faeces and 79 gastrointestinal tracts) of 14 wild carnivore species from 12 Argentine provinces were analyzed. Helminth eggs were identified in 73% of the faecal samples and adult worms were recovered from 81% of the gastrointestinal tracts. We found 19 helminth species. Among the most frequent findings were parasites of domestic carnivores, namely Toxocara canis, Tox...

Toxocara is a roundworm, a common parasite of dogs (T. canis) and cats (T. cati). Toxocariasis or Visceral larva migrans (VLM) are diseases caused by the larvae of Toxocara sp., which may involve many organs, but pulmonary symptoms such as coughing and wheezing and allergic symptoms are seen in more than 80% of patients. It is known that, although the risk of infection is present, the worldwide...

The survey and research programs of the National Agricultural Statistics Service (NASS) of the U.S. Department of Agriculture, require collection and processing of data from a variety of sources: paper questionnaires, CATI and CAPI instruments, even remotely sensed satellite data and digital map data. To manage the analysis and dissemination of these data NASS staff use a wide variety of comput...

The estimation of the size of an elusive population is a problem frequently addressed in many fields of applications. In the paper a sampling strategy for the estimation of the size, named centre sampling, is proposed, and its properties are evaluated in a design-based approach. The estimator is admissible, consistent and the design is measurable. The expressions of the variance of the populati...

Suitable pricing models for Internet services represent one of the main prerequisites for a successfully running implementation of a charging and accounting tool. This paper introduces general aspects influencing the choice of a pricing model and presents a survey of relevant approaches to be found in the scientific literature. Based on cost model investigations some detailed insight into price...

The Differentiated Service (DiffServ) architecture for the Internet implements a scalable mechanism for quality-of-service (QoS) provisioning. Bandwidth brokers represent the instances of the architecture, that automate the provisioning of a DiffServ service between network domains. Although several bandwidth broker implementations (e.g. [Bri98]) have been proposed, the alternatives and trade-o...
