Distinct spectral features at the Fe L-edge of the two compounds K3[Fe(CN)6] and K4[Fe(CN)6] have been identified and characterized as arising from contributions of the ligand pi orbitals due to metal-to-ligand back-bonding. In addition, the L-edge energy shifts and total intensities allow changes in the ligand field and effective nuclear charge to be determined. It is found that the ligand fie...

This paper is about the classification of noun-compounds (NCs) into classes that reflect the semantic relationships between the nouns. I am ultimately interested in the automatic classification of NCs with machine learning techniques. In order to learn the classification (to eventually classify previously unseen NCs) these techniques need as input noun compounds that have been previously classi...

The fate of a comprehensive group of nonylphenol and octylphenol ethoxylates (APEOs) and several of their carboxylated derivatives was studied in three American wastewatertreatment plants (WWTPs), two of which included advanced treatment. Influent and effluent concentrations of the alkylphenolic compounds (APEs) in the three plants were very similar, but effluent concentrations showed a seasona...

Single words have affective and aesthetic properties that influence their processing. Here we investigated the processing of a special case of word stimuli that are extremely difficult to evaluate, bivalent noun-noun-compounds (NNCs), i.e. novel words that mix a positive and negative noun, e.g. 'Bombensex' (bomb-sex). In a functional magnetic resonance imaging (fMRI) experiment we compared thei...

With the establishment of the inadequate efficiency of atropines and oximes in reducing morbidity and mortality of patients poisoned by organophosphates, more attention is given to using other methods such as Fresh Frozen Plasma (FFP) as a bioscavenger to mop up organophosphate toxins. This randomized clinical trial was conducted on 56 organophosphate poisoned patients who were randomly assigne...

Earlier papers from this laboratory have dealt with the activation of urease (1) and of papain (2), with emphasis, particularly, upon reversible inactivations by oxidizing agents and by certain organometallic compounds. This communication describes an investigation of the markedly differing activation chemistry of the enzyme, arginase. There is stressed the conspicuous Ale apparently played by ...

ABSTRACT The copolymerizations of vinyl chloride with o-olefin or acrylic compounds were investigated with organometallic compounds as catalysts. In general, organoaluminium compounds need to be treated with a complexing agent such as tetrahydrofuran prior to use. Otherwise the former reacts with polyvinyl chloride and loses its activity. The copolymer of vinyl chloride and propylene was thus o...

Organoselenium compounds are important tools in the field of synthetic chemistry because their specific reactivities have been used as the key reactions in the synthesis of various organic compounds. Nucleophilic organoselenium reagents are frequently utilized to introduce a selenium atom into organic molecules. However, there is no method available for the direct transformation of a hydroxy gr...
