Social Network Size

Previous studies showed that extraversion influences social network size. However, it is unclear how extraversion affects the size of different layers of the network, and how extraversion relates to the emotional intensity of social relationships. We examined the relationships between extraversion, network size, and emotional closeness for 117 individuals. The results demonstrated that extraverts had larger networks at every layer (support clique, sympathy group, outer layer). The results were robust and were not attributable to potential confounds such as sex, though they were modest in size (raw correlations between extraversion and size of network layer, .20 < r < .23). However, extraverts were not emotionally closer to individuals in their network, even after controlling for network size. These results highlight the importance of considering not just social network size in relation to personality, but also the quality of relationships with network members.

This paper discussed the design–functionality and application of Flexible Electrical Capacitance Tomography sensor (FlexiECT). The sensors consist of 12 electrodes allocated surrounding the outer layer of the pipeline. The sensor is designed in such that the flexibility features suit the applications in the pipeline of multiple size. This paper also discussed the preliminary result of FlexiECT applications in fluid imaging by identifying the percentage of two mixing fluids.

The objective of this work was to compare the hygrothermal responses and the moisture performance of four wood-frame walls as predicted by four hygrothermal (HAM) simulation tools, namely: DELPHIN, WUFI, hygIRC and COMSOL. The four wall systems differ only in their cladding type; these were fibreboard, vinyl, stucco and brick. Three Canadian cities having different climates were selected for simulations: Ottawa, Ontario; Vancouver, British Columbia and Calgary, Alberta. In each city, simulations were run for 2 years. Temperature and relative humidity of the outer layer of OSB sheathing were compared amongst the four simulation tools. The mould growth index on the outer layer of the OSB sheathing was used to compare the moisture performance predicted by the respective hygrothermal simulation tools. Temperature profiles of the outer layer of the OSB sheathing were all in good agreement for the four HAM tools in the three locations. For relative humidity, the highest discrepancies amongst the four tools were found with stucco cladding where differences as high as 20% could be found from time to time. Mould growth indices predicted by the four HAM tools were similar in some cases but different in other cases. The discrepancies amongst the different HAM tools were likely related to: the material property processing, how the quantity of wind-driven rain absorbed at the cladding surface is computed and some implementation details. Despite these discrepancies, The tools generally yielded consistent results and could be used for comparing the impacts of different designs on the risk of premature deterioration, as well as for evaluating the relative effects of climate change on a given wall assembly design.

Abstract Introduction In both partial thickness burns and skin graft donor sites, coverage with Polylactide-based copolymer dressing (PLBC dressing) has been shown to result in expedited healing and improved pain outcomes when compared to more traditional techniques. These advantages are generally attributed to the way in which PLBC remains as an intact coating over the wound bed throughout the healing process, protecting wounds from the contamination and microtraumas associated with changes more conventional dressings. At our institution, we began selectively utilizing PLBC as a means of securing and protecting fresh skin graft, in hopes that we would find similar benefits in this application. Methods Clinical Protocol-- The PLBC dressing was used at the attending surgeon’s discretion. In these cases, meshed STSG was placed over prepared wound beds. Staples were not utilized. PLBC dressing was then placed over the entirety of the graft surface, securing graft in place by adhering to wound bed through intercises. (Staples were not used.) The graft and PLBC complex was further dressed with a layer of non-adherent cellulose based liner with petroleum based lubricant, and an outer layer of cotton gauze placed as a wrap or bolster. Post operatively, the outer layer (“wrap”) of gauze was replaced as needed for saturation. The PLBC and adherent “inner” liner were left in place until falling off naturally over the course of outpatient follow-up. Retrospective Review-- With IRB approval, patients treated PLBC over STSG between April 2018 to March 2019 were identified via surgeon’s log and pulled for review. Documentation gathered from operative notes, progress notes (inpatient and outpatient) and clinical photography was used to identify demographics, mechanism of injury, depth, total body surface area percentage (TBSA%), size of area treated with PLBC dressing, graft loss, need for re-grafting, signs of wound infection, antibiotic treatment, and length of stay. Results Twenty-two patients had STSG secured and dressed with PLBC. Median patient age was 36.5 years. Median TBSA was 5.1%, and median treated area 375 cm2. Follow up ranged from 21 to 232 days post-operatively, with two patients lost to follow up. All patients seen in outpatient follow up were noted to have “complete graft take” or “minimal” graft. None of the areas treated with PLBC dressing required re-grafting. There were no unplanned readmissions, and no wound infections were diagnosed or treated. Practitioners in in-patient setting and in follow up clinic reported satisfaction with the PLBC dressing. Conclusions The PLBC dressing was a feasible solution for securing and dressings STSGs. Future work is needed to determine whether its use is associated with an improvement in patient outcomes.
