An Ir(I) complex of an acetamidinato ligand was synthesized by reaction of N,N'-diphenylacetamidine, PhN[double bond, length as m-dash]C(Me)NHPh, with either MeLi and [{Ir(cod)}2(μ-Cl)2] or [{Ir(cod)}2(μ-OMe)2] and was characterized by X-ray crystallography as a mononuclear complex, [Ir{PhNC(Me)NPh}(cod)] (1; where cod = 1,5-cyclooctadiene). Reaction of 1 with CO afforded a dinuclear carbonyl c...

An (alkene)peroxoiridium(III) complex, [Ir(L)(cod)(O(2))] [where LH = PhN=C(NMe(2))NHPh and cod = 1,5-cyclooctadiene], was identified as an intermediate in the reaction of the Ir(I) precursor [Ir(L)(cod)] with O(2) and characterized by spectroscopic methods. Decay of the intermediate and further reaction with 1,5-cyclooctadiene produced 4-cycloocten-1-one.

A variety of mononuclear alkene complexes, [Ir{ArNC(NR2)NAr}(cod)], and dicarbonyl complexes, [Ir{ArNC(NR2)NAr}(CO)2] (where R = Me or Et; Ar = Ph, 4MeC6H4, 4-MeOC6H4, 2,6-Me2C6H3 or 2,6-Pr2C6H3; and cod = 1,5-cyclooctadiene), were synthesized from the neutral N,N-dialkyl-N′,N′′-diarylguanidines via deprotonation and transmetalation. These complexes were fully characterized by spectroscopic tec...

Knowledge of the spatial distribution of juvenile cod is essential for obtaining precise recruitment data to conduct sustainable management of the eastern and western Baltic cod stocks. In this study, the horizontal and vertical distribution and density patterns of settled juvenile 0- and 1-group Baltic cod are determined, and their nursery areas are localised according to the environmental fac...

OBJECTIVE This paper assesses the quality of the underlying cause of death (COD) statistics in Hermosillo, Mexico in a random sample of 300 in-hospital adult deaths. MATERIAL AND METHODS A "gold standard" COD, determined by a systematic review of hospital medical charts, was compared to the COD reported by the vital registry system. RESULTS Overall agreement between the reviewer and origina...

The food and feeding of Flemish Cap cod are described for 5 years based on 3921 stomachs collected in the fishing grounds off the Flemish Cap, Newfoundland in summer 1989–1993. Feeding intensity was high but the prey spectrum was narrow in all years with hyperiids and redfish (Sebastes sp.) predominating. Squid and polychaetes had a high inter-annual variability. Juvenile cod diet was dominated...

Taking advantage of robust facet passivation, we unveil a laser "fossil" buried within a broad area laser diode (LD) cavity when the LD was damaged by applying a high current. For the first time, novel physical phenomena have been observed at these dramatically elevated energy densities within the nanoscale LD waveguide. The observation of the laser "fossil" is interpreted with different mechan...

The removal of COD and oil from dairy wastewater was experimentally investigated using direct current (DC) electrocoagulation (EC). In the EC of dairy wastewater, the effects of initial pH, electrolysis time, initial concentration of COD, and current intensity were examined. The COD in the aqueous phase were effectively removed when aluminum plates were used as sacrificial electrodes. The optim...

BACKGROUND This study examines emotion regulation strategies used by children of mothers with childhood-onset depression (COD) and children of never-depressed mothers (NCOD). METHODS Participants were 49 COD offspring (ages 4-7) and 37 NCOD offspring (ages 4-7) and their mothers. Emotion regulation strategies were assessed observationally during a laboratory mood induction paradigm. RESULTS...

The predatory behavior of a carnivorous marine copepod, Euchaeta norvegica Boeck, feeding on eggs and larvae of the North Atlantic cod Gadus morhua L. was examined. In the laboratory, adult females of Euchaeta norvegica did not feed on eggs. Predation rates on yolk-sac larvae and starved post-yolk-sac larvae did not vary significantly with age up to 14 days old because of little change in size ...
