Intensity-Dependent Enhancement of Saturable Absorption in PbS-Au4 Nanohybrid Composites: Evidence for Resonant Energy Transfer by Auger Recombination

Intensity-dependent enhancement of saturable absorption in a film of PbS-Au4 nanohybrid composites has been observed by femtosecond time-resolved transient absorption measurement at 780 nm. The nonlinear absorption coefficient of saturable absorption in PbS-Au4 nanohybrid composites is found to be dependent on excitation irradiance and it is determined to be -2.9 cm/GW at 78 GW/cm2, an enhancement of nearly fourfold in comparison with that of pure PbS quantum dots (QDs). The enhancement is attributed to excitation of surface plasmon by resonant energy transfer between PbS QDs and Au nanoparticles through Auger recombination.Comment: 14 pages, 3 figures.

Use of available storage to improve scheduling in an automobile assembly plant

The Final Assembly Plant at General Motors-Holden's Automotive Ltd converts painted body shells into drive-away vehicles. It encounters difficulties when processing certain sequences of vehicles with high work contents, so GMHAL wishes to schedule its input to reduce or eliminate such undesirable sequences. GMHAL has a set of empirical rules for delineating undesirability. The Painted Body Storage (PBS), which precedes Final Assembly, has 4 lanes that can be used to partially reschedule a vehicle sequence. Information on vehicle work content is available prior to arrival at the PBS, and GMHAL wants advice on using this data and the PBS to achieve a more satisfactory input to Final Assembly. The Study Group devised three approaches. 1. Use the rules to show which short sequences are desirable and devise input and output strategies for the PBS to achieve these consistently. Choice between the strategies requires further investigation. 2. Model Final Assembly to produce an optimality criterion for vehicle sequences and use combinatorial optimization methods to optimise it over possible PBS outputs. A characterization of these outputs was derived. 3. Suggest that the initial production be suitably scheduled, which may substantially reduce the difficulties at the PBS stage

Effect of Oocyte Vitrification Before and After in Vitro Maturation Towards Bcl-2, Bax and Bcl-2/Bax Ratio Expression

Objectives: to compare the expression of Bcl-2, Bax and Bcl-2/Bax ratio in cumulus cell and oocyte between vitrified oocyte pre and post in vitro maturation.Materials and Methods: Maturation was operated in medium TC 100 µl for 24 hours. Vitrification begins with washing oocyte in PBS basic medium supplemented of 20% serum for 1-2 minutes, followed by equilibration medium PBS + 20% serum + 10% ethylene glycol for 10-14 minutes, then transferred to 20% serum + PBS + 0.5 M sucrose + 15% ethylene glycol + PROH 15% for 25-30 seconds. Thawing is processed by submerging the oocytes in the media: 1). PBS + 20% serum + 0.5 M sucrose, 2). PBS + 20% serum + 0.25 M sucrose, and 3). PBS + 20% serum + 0.1 M sucrose. Imunocytochemistry observed the expression of Bcl-2, bax and Bcl-2/bax ratio.Results: Bcl-2 expression on oocyte in control group differed significantly with treatment group, Bcl-2 expression on cumulus in control group differed significantly with treatment 1 group. Bax expression on oocyte in control group differed significantly with treatment group. Bax expression on cumulus in control group differed significantly with treatment group. Bcl-2/Bax expression ratio on oocyte and cumulus did not differ significantly in all groupConclusion: No difference Bcl-2/Bax expression ratio on oocyte and cumulus between vitrified oocyte pre and post in vitro maturation

The effects of motivational climate interventions on psychobiosocial states in high school physical education

Purpose: The purpose of this study was to examine the effects of task- and ego-involving climate manipulations on students’ climate perception and psychobiosocial (PBS) states in a physical education setting. Method: Two subsamples of female students (N = 108, 14-15 years of age) participated for 12 lessons on either a task- or an ego-involving climate intervention as grounded in the TARGET model. Results: At the end of the treatment, the participants of the ego-involved group reported lower scores in perceived task-involving climate and higher scores in perceived ego-involving climate than their peers in the task-involved group. Lower scores in pleasant/functional PBS states and higher scores in unpleasant/dysfunctional PBS states were also observed in the ego-involved group as a consequence of the intervention. Conclusion(s): Findings suggested that teacher’s induced achievement motivational climates can influence students’ perceptions and prompt PBS states consistent with the motivational atmosphere

Applicability of trials in rheumatoid arthritis and osteoarthritis: A systematic review and meta-analysis of trial populations showing adequate proportion of women, but underrepresentation of elderly people

Objectives: To evaluate whether elderly people and women are adequately represented in randomized controlled trials (RCT) in rheumatoid arthritis (RA) and osteoarthritis (OA). Methods: Four systematic searches in MEDLINE yielded RCT in RA and OA on any intervention published in 2016 and 2017 and population-based studies (PBS) in RA and OA published between 2013 and 2017. Random effects meta-analyses estimated the pooled proportion of elderly people (defined as being ≥ 65 years old), the mean age, its standard deviation (SD), and the proportion of women stratified by disease (RA and OA) and study type (RCT and PBS). Stratified estimates were subsequently compared. Results: 265 RCT comprising 51,240 participants and 53 PBS comprising 523,630 participants were included. In both RA and OA, RCT included lower proportions of elderly people than PBS: RA –0.18 (95% confidence interval –0.22 to –0.13); OA –0.20 (–0.30 to –0.09); had lower mean ages: RA –5.2 years (–6.8 to –3.5); OA –4.7 years (–7.5 to –2.0); and smaller SD: RA –1.9 years (–2.6 to –1.3); OA –2.7 years (–4.2 to –1.2); (all comparisons: p ≤ 0.001). Proportions of women were comparable in RCT compared to PBS in both RA and OA. Conclusions: While women are adequately represented in RA and OA trials, the elderly are underrepresented, probably limiting applicability of current evidence to this growing subgroup. It is urgent to improve the inclusion of elderly people in clinical trials and study age as a determinant for outcome

Knowledge management and organizational culture

This paper explores the relationship between organisational knowledge, organisational culture, and Process Based Systems (PBS), in the U.K. National Health Service (NHS). Links between PBS and organisational culture have been observed before(Perry, 2003); the contribution made by PBS to organisational knowledge has also been suggested (Perry, 2004). However, links between organisational knowledge and organisational culture in the NHS have not been widely studied. A qualitative study of these links across clinical functions has been used in conjunction with a literature review to consider in particular the use of tacit knowledge and the role that might be played by PBS in mediating and sharing this "embedded" or experiential form of knowledge. While there may be some opportunity for "externalisation" (Nonaka, 1994) - the conversion of tacit to explicit knowledge, this paper argues that PBS may also contribute to "socialisation" - the direct generation of tacit knowledge by tacit knowledge.Process Based Systems, knowledge management, organisational culture
