The Reverse Water-Gas Shift reaction (RWGS) allows the conversion of CO2 to syngas, a mixture of H2 and CO, used to manufacture most chemicals and synthetic fuels. Consequently, it is...

The WalkinSense Ò is a relatively new device designed to monitor walking exercise. The purpose here was to assess its reliability and accuracy when analysing spatial-temporal gait parameters. Forty-two young adults performed 3 3 400 m walking at moderate intensity on a 400-m standard track, using both the WalkinSense and a pedometer. The betweentrial reliability was excellent for all variables, with intraclass correlation coefficient values ranging from 0.90 to 0.98. The absolute and percentage differences between the WalkinSense and the track length were (mean 6 standard deviation) 236.7 6 45.0 m (95% confidence interval: 244.6, 28.6) and 9.2 6 11.3% (95% confidence interval: 211.2, 7.2), respectively. The absolute and percentage differences between the WalkinSense and the pedometer for number of strides were 0.7 6 10.5 strides (95% confidence interval: 21.2, 2.6) and 0.1 6 4.0% (95% confidence interval: 20.7, 0.8), respectively. The WalkinSense system showed excellent reliability for assessing spatial-temporal gait parameters. Considering accuracy, users should be aware of the limitations of the device, which in this study ranged between 20.7% and 0.8% and between 211.2% and 7.2%, for number of strides and travelled distance, respectively.

The main goal of this work was to design a new product containing an active ingredient of the Eucalyptus Globulus tree - its essential oil. This work was divided into four steps: analysis of the raw material, chemical product design (needs, ideas, and product selection), manufacture, and economic analysis. After investigating the potential of all the ideas, the product selected was a plaster in gel, named Eucatrigel, with triple action: it protects the wound, accelerates the healing (due to the essential oil addition), and waterproofs the region. In the manufacturing step, it was defined the mass percentage of the essential oil in the gel as 0.5 %. The formula of the gel was based on a patent (US8563604B2) owned by Bausch Health Companies. A business case was set for the economic evaluation of this product; in this case, considering an initial investment of 681 k€, the expected payback period is four years, and the internal rate of return is 35 %.
