A method is described whereby dielectrophoresis of algal cells is used to perform rapid water quality analysis, specifically detecting the presence of CuSO4. The dielectric collection spectrum of the fresh water alga Selenastrum capricornutum was determined for a range of concentrations of CuSO4 from 25 mg L(-1) to 0.25 mg L(-1) for exposure times of 15 min and 18 h. In all cases increasing the...

The present study demonstrates a methodology for optimization of environmental data acquisition. Based on the premise that the worth of data increases in proportion to its ability to reduce the uncertainty of key model predictions, the methodology can be used to compare the worth of different data types, gathered at different locations within study areas of arbitrary complexity. The method is a...

The unified property roughly states that searching for an element is fast when the current access is close to a recent access. Here, close refers to rank distance measured among all elements stored by the dictionary. We show that distance need not be measured this way: in fact, it is only necessary to consider a small working-set of elements to measure this rank distance. This results in a data...

-Serial serum diphenylhydantoin and urinary 5-(p-hydroxyphenyl)-5phenylhydantoin concentrations were determined in 8 patients with malignant disease and 4 healthy volunteers on 2 separate occasions after an oral dose of diphenylhydantoin (500 mg). No significant difference was observed between metabolism before and 10 days after immunization with BCG or Corynebacterium parvum. Volunteers withou...

Following a historical survey of the views generally held regarding the essential lesion underlying sciatica, the writer elaborates his own view that sciatica is really an affection of the hip-joint, rheumatic or gouty in origin. The steps by which he arrives at this opinion are ingenious and reasonable. They are anatomical and clinical, and are fully considered in the book, which should be con...

I study the possibility of baryogenesis can take place in fresh inflation. I find that it is possible that violation of baryon number conservation can occur during the period out-of-equilibrium in this scenario. Indeed, baryogenesis could be possible in the range of times (109 − 1012) G1/2, before the thermal equilibrium is restored at the end of fresh inflation.

Many fresh pork products, in particular, fresh lean pork products, are nutrient-dense sources of protein and several other nutrients. The purpose of this study was to estimate nutritional contributions of fresh and fresh lean pork to adults' diets in the United States. Mean total nutrient intakes by fresh and fresh lean pork consumers on a day of recall were compared with intakes by nonconsumer...
