We show that any semi-algebraic sweeping process admits piecewise absolutely continuous solutions, and any such bounded trajectory must have finite length. Analogous results hold more generally for sweeping processes definable in o-minimal structures. This extends previous work on (sub)gradient dynamical systems beyond monotone sweeping sets.

adenoviruses (advs) types 40 and 41 are the causative agents of diarrhea in children. hence, rapid sensitive and specific detection of these viruses are of clinical importance. the customary methods such as propagation of virus in cell culture suffer from limitations. detection of immobilized amplified products in a one phase system (diapops) method has the potential to overcome these problems....

A two-way finite automaton is sweeping if its input head can change direction only on the end-markers. For each n ≥ 2, we exhibit a problem that can be solved by a O(n)-state sweeping LasVegas automaton, but needs 2 states on every sweeping deterministic automaton.

OBJECTIVES To explore chimney sweeping work tasks, chimney sweeps' use of protective equipment, and type of fuel used by clients, over time. Further, to assess work-relatedness of current eye and airway symptoms. METHODS In a cross-sectional study in 2011, male Swedish chimney sweeps (n = 483; age 21-69 years) answered a questionnaire about their occupational history and eye and airway sympto...

A sweeping technique, in conjunction with micellar electrokinetic chromatography, for the simultaneous determination of flunitrazepam and its major metabolites, 7-aminoflunitrazepam and N-desmethylflunitrazepam, is described. The optimized conditions for the sweeping and separation were a pH 9.5 buffer, 25mM borate, 50mM cetyltrimethylammonium bromide, 30% MeOH (v/v), and a 151-mm injection len...

The use and limitations of a methanol plug assisted sweeping-micellar electrokinetic chromatography (sweeping-MEKC) method is described. Using naphthalene-2,3-dicarboxaldehyde (NDA)-labeled dopamine as a model compound, this new method was also used in the determination of dopamine in actual urine samples. An inexpensive violet light emitting diode (LED) was used for the light source, because t...

Two new antibiotics, A-218 and K-41, were isolated from strains identified as Streptomyces hygroscopicus. The antibiotics are characterized as polycyclic polyether compounds and are active against gram-positive bacteria.
