Their topics include selenium-halogen and tellurium-halogen reagents, organo-selenium and organo-tellurium compounds containing chalcogen-oxygen bonds in organic syntheses or related processes, the synthesis and coordination chemistry of cyclic selenoureas and telluroureas, selenium and tellurium electrophiles in organic synthesis, and recent advances in the self-assembly of polynuclear
metal-selenium and metal-tellurium compounds from 14-16 reagents.
This technique consists in the addition of salts (usually aluminum or iron salts) which in the presence of water hydrolyze, forming multicharged polynuclear
complexes that interact with impurities.
Cerebrospinal fluid analysis (CSF) showed elevated presure (290 mmH[sub]2O), increased protein (74 mg/dl), and polynuclear
leukocytes (257 per view).
Following his time at DRI, he worked in the Food Safety and Environmental Stewardship laboratory at Oregon State University in Corvallis, Oregon, a toxicology lab where he concentrated on the environmental fate of Polynuclear
aromatic hydrocarbons (PAHs) contain carbon and hydrogen with a bonded ring, holding at least two benzene rings .
Chemical parameters (metals and organic compounds, such as polynuclear
aromatic hydrocarbons and herbicides) were determined in order to calculate the plant's impact on human toxicity (non-cancer), human toxicity (cancer) and freshwater toxicity, by applying the standard protocol of PEF/OEF.
There was no central necrosis or evidence of polynuclear

aromatic hydrocarbons in aerosol by solid-phase extraction and gas chromatography-mass spectrum," Talanta, vol.
neoformans is associated with the ability to cause a cellular destruction of polynuclear
cells: Engulfed by the host cells, the pathogen replicates and then destroys the cells.
These include the mononuclear species U[O.sub.2]O[H.sup.+], U[O.sub.2][(OH).sub.2](aq) (also written as U[O.sub.3](aq)), U[O.sub.2][(OH).sub.3.sup.-](HU[O.sup.4-]), and U[O.sub.2][(OH).sub.4.sup.2-](U[O.sub.4.sup.2-]) and polynuclear
species such as [(U[O.sub.2]).sub.2][(OH).sub.2.sup.2+], [(U[O.sub.2]).sub.3][(OH).sub.4.sup.2+], [(U[O.sub.2]).sub.3][(OH).sub.5.sup.+], [(U[O.sub.2]).sub.3][(OH).sub.7.sup.-], and [(U[O.sub.2]).sub.4][(OH).sub.7.sup.+] [30, 77-79].
Biological examinations revealed a hyperleucocytosis with 11874 leukocytes/ml, predominantly polynuclear
neutrophils, and a normal level of serum albumin at 38 g/l.
