The aims of this study were: to assess current practice in smoking cessation interventions by midwives and to examine the relationship between the use of smoking intervention, practitioner characteristics and organizational factors. A mail-out survey was sent to a random sample of 500 midwives. The response rate was 85% (n = 425). The results indicated that most midwives used minimal interventions (advice and education) for at least some of their clients. However, the more skilled and more time-intensive forms of intervention such as counselling about methods to quit, negotiating a quit date and follow-up were infrequently utilized. Moreover, participants estimated that half their smoking clients were not offered any advice about smoking. Organizational factors such as: hospital policy for smoking intervention, type of hospital, size of hospital, cohesion of staff and work pressure predicted the use of smoking interventions. Self-reported ability to intervene for smoking and the level of assessment undertaken were practitioner characteristics which predicted the use of smoking interventions. The barriers that inhibit the use of smoking intervention by midwives are discussed and methods for change canvassed. 相似文献

Experimental results demonstrating nearly complete mode-selective evanescent coupling to a photonic crystal waveguide from an optical fibre taper are presented. Codirectional coupling with 98% maximum power transfer to a photonic crystal waveguide of length 65 /spl mu/m and with a coupling bandwidth of 20 nm is realised. 相似文献

In a search for a preferred source of γ-linolenic (all-cis-6,9,12-octadecatrienoic) acid, seed oils of 33 species of Boraginaceae were examined. The desired triene was found primarily
in the subfamily Boraginoideae in amounts ranging from 0.2 to 18%. Oils of this subfamily also contain 0.2 to 15% of the tetraene,
all-cis-6,9,12,15-octadecatetraenoic acid. Total unsaturation and the relative proportions of the common acids varied widely in oils
of the family. Monoene predominated in the subfamily Cordioideae, diene in Heliotropioideae, and a diverse composition among
the Boraginoideae; seven had iodine values of 200 or above.Cordia verbenacea seed oil was unique among those examined in having 43% of C20 acids and 23% of components more volatile in gas chromatography than the usual triglycerides.
Presented at AOCS meeting, New Orleans, May 1967. Earlier papers of this series carried the running title “Search for New
Industrial Oils.” The revised title is more appropriate for the basic chemical compositional data reported, that can be useful
in a broader context than originally implied.

The fate of 14 antidepressants along with their respective N-desmethyl metabolites and the anticonvulsive drug carbamazepine (CBZ) was studied in 5 different sewage treatment plants (STPs) across Canada. Using two validated LC-MS/MS analytical methods, the concentrations of the different compounds were determined in raw influent, final effluent and treated biosolids samples. Out of the 15 compounds investigated, 13 were positively detected in most 24-h composite raw influent samples. Analysis showed that venlafaxine (VEN), its metabolite O-desmethylvenlafaxine (DVEN), citalopram (CIT), and CBZ were detected at the highest concentrations in raw influent (up to 4.3 μg L−1 for DVEN). Cumulated results showed strong evidence that primary treatment and trickling filter/solids contact has limited capacity to remove antidepressants from sewage, while activated sludge, biological aerated filter, and biological nutrient removal processes yielded moderate results (mean removal rates: 30%). The more recalcitrant compounds to be eliminated from secondary STPs were VEN, DVEN and CBZ with mean removal rates close to 12%. Parent compounds were removed to a greater degree than their metabolites. The highest mean concentrations in treated biosolids samples were found for CIT (1033 ng g−1), amitriptyline (768 ng g−1), and VEN (833 ng g−1). Experimental sorption coefficients (Kd) were also determined. The lowest Kd values were obtained with VEN, DVEN, and CBZ (67-490 L kg−1). Sorption of these compounds on solids was assumed negligible (log Kd ≤ 2). However, important sorption on solids was observed for sertraline, desmethylsertraline, paroxetine and fluoxetine (log Kd > 4). 相似文献

In his State of the Union speech, the president again called for a Clean Energy Standard. Senator Jeff Bingaman (D-NM) introduced S. 2146. Compliance is phased in, with 8 percent of the largest utilities needing 24 percent clean energy by 2015 and all utilities needing 84 percent clean energy by 2035. There are no energy source mandates that let “the market… determine the best paths forward.” 1 “Clean energy” includes renewables, nuclear, clean coal, and efficient natural gas. 相似文献

2B4 is a cell surface glycoprotein related to CD2 and implicated in the regulation of natural killer and T lymphocyte function. A recombinant protein containing the extracellular region of mouse (m)2B4 attached to avidin-coated fluorescent beads bound to rodent cells, and binding was completely blocked by CD48 monoclonal antibodies (mAbs). Using surface plasmon resonance, we showed that purified soluble mCD48 bound m2B4 with a six- to ninefold higher affinity (Kd approximately 16 microM at 37 degreesC) than its other ligand, CD2. Human CD48 bound human 2B4 with a similar affinity (Kd approximately 8 microM). The finding of an additional ligand for CD48 provides an explanation for distinct functional effects observed on perturbing CD2 and CD48 with mAbs or by genetic manipulation. 相似文献
