We have used dioxygen, not artificial oxidants such as peracids, iodosylarenes, and hydroperoxides, in the generation of a mononuclear nonheme oxoiron(IV) complex, [Fe(IV)(TMC)(O)]2+ (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane), from its corresponding Fe(II) complex, [Fe(TMC)(CF3SO3)2]. The formation of oxoiron(IV) species by activating dioxygen was markedly dependent on iron(...
Neutron detection efficiency of superheated drops of Freon-22 for neutrons obtained from a 3 curie Am-Be neutron source has been reported in this paper. Although Freon-22 having lower boiling point than many other similar liquids (e.g.Freon-12, Freon-114, Isobutane) is expected to be more sensitive to neutrons ,it has not been reported so far and therefore this paper constitutes the first repor...
The prevalence of obesity is high in older persons and recent trends show a rapid increase in this prevalence. Results from observational and intervention studies (i.e. weight loss studies) show the strong negative impact of obesity on functional status in old age. There are different potential pathways through which obesity may lead to functional decline in older persons. Furthermore, the pres...
Introduction Hydrocolpos is an uncommon congenital disorder consisting of cystic dilatation of the vagina caused by obstruction of the distal genital tract, resulting in retained fluid. If there is also associated uterine enlargement, the term hydrometrocolpos is applied. Vaginal obstruction may result from a high vaginal septum, varying degrees of vaginal atresia, cloacal malformations, or an ...
Fungicide resistance in dollar spot caused by Sclerotinia homoeocarpa is a common problem on golf courses in North America (Figure 1) (2), and managing fungicide resistance is a complex and controversial topic (1,4). With dollar spot, the question of whether to use the same fungicide until resistance develops or to rotate different chemistries and tank mixtures has not been defi nitively answer...
poning sexual activity, and reproductive health educators who traditionally provide information about contraception and disease prevention (information that is not part of the curriculum) eventually came to support ENABL’s approach for middle school youths.5 Three and one-half years after its launch, ENABL had evolved from a groundbreaking health education campaign into a way of life for the ag...
This study compares brain activation during causal attribution to three different loci, the self, another person and the situation; and further explores correlations with clinical scales (i.e. depression, anxiety and autism) in a typical population. While they underwent functional magnetic resonance imaging, 20 participants read short sentences about another person ( someone ) who engaged in be...
