Literature describes that a well-maintained moist wound healing environment leads to faster healing by preventing scabbing and drying of the wound. A moist wound speeds healing by allowing for unimpeded movement of newly dividing epidermal cells in the wound. Contrary to what is described in literature and practiced by clinicians, first-aid dressings used at home by consumers advertise breathability and absorptivity as benefits. This manuscript examines the effects of dressing breathability and highly absorptive pads on healing and wound appearance in a porcine dermatome wound model, designed to mimic an abrasion injury. Partial thickness wounds were covered with an experimental silicone-polymer film dressing and various over-the-counter bandages for time frames ranging from 4 to 11 days. The progression of healing was quantified by histology and wound-size reduction measurements. The thickness and persistence of a scab or serocellular crust (SCC) over the injury was measured using both pixel density and optical coherence tomography to supplement visual observations, demonstrating new tools for quantification of SCC over wounds. The results of the experiments illustrate the impact of dressing features on the rate of wound reepithelialization and the formation of SCC. Both a low moisture vapor transmission rate (MVTR) and the absence of an absorptive layer were important in speeding wound healing. Surprisingly, use of a dressing with a low MVTR and a highly absorptive pad healed significantly more slowly than a comparative dressing with a low MVTR and no absorptive pad, even though both dressings had very little scab formation over the wound. This study shows that breathability and absorbency of dressings play independent roles in providing an optimal healing environment, and that these properties can vary widely among commercially available dressings.

Coercion remains a central aspect of many people's mental healthcare. It can include the use of legislation to restrict freedoms, the use of physical restraint, the restriction of freedom of movement and/or association, and the forced or covert administration of medication. There is good evidence that the use of such measures can traumatise service users. This article reports the findings of a survey of service users regarding their experiences of coercion and restraint and embeds this in the wider international and institutional environment.

Gamma-ray excitation functions have been measured for 30, 42, 54 and 66 MeV proton beams accelerated onto C + O (Mylar), Mg, Si, and Fe targets of astrophysical interest at the separate-sector cyclotron of iThemba LABS in Somerset West (Cape Town, South Africa). A large solid angle, high energy resolution detection system of the Eurogam type was used to record Gamma-ray energy spectra. Derived preliminary results of Gamma-ray line production cross sections for the Mg, Si and Fe target nuclei are reported and discussed. The current cross section data for known, intense Gamma-ray lines from these nuclei consistently extend to higher proton energies previous experimental data measured up to Ep ~ 25 MeV at the Orsay and Washington tandem accelerators. Data for new Gamma-ray lines observed for the first time in this work are also reported.

The minuteness of the nuclear binding energy requires that mass measurements be highly precise and accurate. Here we report on new measurements $^{29-33}$Mg and $^{26}$Na performed with the {\sc Mistral} mass spectrometer at {\sc Cern}'s {\sc Isolde} facility. Since mass measurements are prone to systematic errors, considerable effort has been devoted to their evaluation and elimination in order to achieve accuracy and not only precision. We have therefore conducted a campaign of measurements for calibration and error evaluation. As a result, we now have a satisfactory description of the {\sc Mistral} calibration laws and error budget. We have applied our new understanding to previous measurements of $^{26}$Ne, $^{26-30}$Na and $^{29,32}$Mg for which re-evaluated values are reported.
