Porous silica spheres as indoor air pollutant scavengers

Porous silica spheres were investigated for their effectiveness in removing typical indoor air pollutants, such as aromatic and carbonyl-containing volatile organic compounds (VOCs), and compared to the commercially available polymer styrene-divinylbenzene (XAD-4). The silica spheres and the XAD-4 resin were coated on denuder sampling devices and their adsorption efficiencies for volatile organic compounds evaluated using an indoor air simulation chamber. Real indoor sampling was also undertaken to evaluate the affinity of the silica adsorbents for a variety of indoor VOCs. The silica sphere adsorbents were found to have a high affinity for polar carbonyls and found to be more efficient than the XAD-4 resin at adsorbing carbonyls in an indoor environment

Examining the impact of comorbid serious mental illness on rehospitalization among medical and surgical inpatients

Multiple barriers to quality health care may affect the outcomes of postacute treatment for individuals with serious mental illness (SMI). This study examined rehospitalization for medical and surgical inpatients with and without a comorbid diagnosis of SMI which included psychotic disorders, bipolar disorder and major depressio

Microstructural strain energy of α-uranium determined by calorimetry and neutron diffractometry

The microstructural contribution to the heat capacity of α-uranium was determined by measuring the heat-capacity difference between polycrystalline and single-crystal samples from 77 to 320 K. When cooled to 77 K and then heated to about 280 K, the uranium microstructure released (3±1) J/mol of strain energy. On further heating to 300 K, the microstructure absorbed energy as it began to redevelop microstrains. Anisotropic strain-broadening parameters were extracted from neutron-diffraction measurements on polycrystals. Combining the strain-broadening parameters with anisotropic elastic constants from the literature, the microstructural strain energy is predicted in the two limiting cases of statistically isotropic stress and statistically isotropic strain. The result calculated in the limit of statistically isotropic stress was (3.7±0.5) J/mol K at 77 K and (1±0.5) J/mol at room temperature. In the limit of statistically isotropic strain, the values were (7.8±0.5) J/mol K at 77 K and (4.5±0.5) J/mol at room temperature. In both cases the changes in the microstructural strain energy showed good agreement with the calorimetry

Fast-track pathway for elective caesarean section: a quality improvement initiative to promote day 1 discharge.

Enhanced recovery after surgery (ERAS) aims to improve perioperative care, hasten recovery to the normal physiological state and shorten length of stay (LoS). There is evidence that ERAS programmes following elective caesarean section (ELCS) confer benefit through faster return to physiological state and reduced LoS for mother and baby. Baseline audit of ELCS in 2013 revealed a mean LoS of 3 days. We piloted an ERAS discharge pathway promoting day 2 discharge, which rose from 5.0% to 40.2%. 19.2% of women went home on day 1. Many women fed back that they would prefer day 1 discharge. We hypothesised that a day 1 discharge pathway for low-risk women could benefit both women and services at our maternity unit. From October 2015, we developed a 'fast-track pathway' (FTP) using a Plan-Do-Study-Act approach. Between October 2015 and April 2016, we prospectively audited clinical outcomes, LoS and maternal satisfaction from all women placed on the FTP. We held regular multidisciplinary team meetings to allow contemporaneous analysis. Satisfaction was analysed by Likert scale at postoperative surveys. Women were identified in antenatal clinic after meeting predefined low-risk criteria. 27.3% of women (n=131/479) delivering by ELCS entered the FTP. 76.2% of women on the FTP were discharged on day 1. Mean LoS fell to 1.31 days. 94.2% of women who established breast feeding at day 1 were still breast feeding at 7 days. Overall satisfaction at day 7 was 4.71 on a 5-point Likert scale. 73.1% of women reported good pain control. Additional financial savings are estimated at £99 886 annually. There were no related cases of readmission. Day 1 discharge after ELCS is safe and acceptable in carefully selected, low-risk women and has high satisfaction. There may be resultant financial savings and improved flow through a maternity unit with no detected adverse effect on breast feeding, maternal morbidity or postnatal readmissions

Developing the task and ego orientation at work questionnaire

Although widely researched in education and sport, little research examines employee achievement goal orientations in a work context. This article provides validity and reliability evidence for the Task and Ego Orientation at Work Questionnaire (TEOWQ) from a study of378 employees representing from eight different occupational categories. Confirmatory factor analyses indicate that are-specified model comprising two ego (&quot;Being the best&quot; and &quot;being better than others&quot;) and two task sub-factors (&quot;Learning&quot; and &quot;Effort&quot;) fit the data better than the original two-factor model. Temporal stationarity and stability of the constructs over time receive support. As hypothesized, task and task-effort orientations relate positively with persistence while ego orientation does not. The TEOWQ appears to be a valid and reliable instrument of achievement orientation in a work setting.<br /
