The stingless bee Melipona scutellaris is an important pollinator in northeastern Brazil because it is endemic to this region. Both deforestation and timber harvesting have reduced the nesting sites for this species, thus reducing its population and range. Genetic studies may help reverse this process by providing im...
متن کاملThe Influence of Accounting Information Use on Small Farm Inefficiency
This paper aims to estimate a translog stochastic frontier production function in the analysis of a balanced panel of 147 mixed Catalan farms in a five-year period (1989-1993), in order to attempt to measure and explain variation in output inefficiency scores with a one-stage approach. The mean output efficiency in the period analysed was estimated to be 62.3%. Using techniques for confidence i...

reference spectra for the organism and its close relatives (e.g., B. thailandensis). B. pseudomallei, although different from other Burkholderia spp. in its pathogenicity and epidemiology, is not easily discriminated from B. thailandensis or B. cepacia complex by using phenotypic tests (10). In summary, infection with B. pseudomallei should be considered in patients with pneumonia after travel ...
