Towards the design of non-amyloidogenic proteins

Glucose oxidase was immobilized onto poly(2-hydroxyethyl methacrylate) (pHEMA) membranes by two methods: by covalent bonding through epichlorohydrin and by entrapment between pHEMA membranes. The highest immobilization efficiency was found to be 17.4% and 93.7% for the covalent bonding and entrapment, respectively. The K_m values were 5.9 mmol dm^?3, 8.8 mmol dm^?3 and 12.4 mmol dm^?3 for free, bound and entrapped enzyme, respectively. The V_max values were 0.071 mmol dm^?3 min^?1, 0.067 mmol dm^?3 min^?1 and 0.056 mmol dm^?3 min^?1 for free, bound and entrapped enzyme. When the medium was saturated with oxygen, K_m was not significantly altered but V_max was. The optimum pH values for the free, covalently-bound and entrapped enzyme were determined to be 5, 6, and 7, respectively. The optimum temperature was 30°C for free or covalently-bound enzyme but 35°C for entrapped enzyme. The deactivation constant for bound enzyme was determined as 1.7 × 10^?4 min^?1 and 6.9 × 10^?4 min^?1 for the entrapped enzyme.

A diagnostic expert system for the dyeing of protein fibres

Coloration of protein fibres is characterised by many variables, each with a different effect on the final product. Because the process can be rather complicated, it is often difficult to achieve the right colour in the first dyeing attempt. Determining the root causes of a given problem tends to be even more challenging. While quality requirements in the textile industry have become increasingly rigorous, seasoned coloration experts have become rather scarce. This situation has exacerbated the need for the development and implementation of expert systems to augment available expertise in this domain. In addition, benefits associated with computer‐based diagnostic systems have become increasingly evident over the past few decades, and the field remains an active area of research. Here we report the design and development of a diagnostic expert system for the dyeing of protein fibres. The system is designed to aid in the identification of root causes of problems with a view to enabling users to arrive quickly at remedial solutions. The performance of the system has been tested and evaluated by human experts and deemed to be highly satisfactory. This diagnostic system can be used to teach students, may be utilised by novice colourists as a problem‐solving tool, and may be employed as a supplementary knowledge resource by seasoned dyers.     

Towards design guidelines for virtual reality training for the chemical industry

Operator training in the chemical industry is important because of the potentially hazardous nature of procedures and the way operators' mistakes can have serious consequences on process operation and safety. Currently, operator training is facing some challenges, such as high costs, safety limitations and time constraints. Also, there have been some indications of a lack of engagement of employees during mandatory training. Immersive technologies can provide solutions to these challenges. Specifically, virtual reality (VR) has the potential to improve the way chemical operators experience training sessions, increasing motivation, virtually exposing operators to unsafe situations, and reducing classroom training time. In this paper, we present research being conducted to develop a virtual reality training solution as part of the EU Horizon 2020 CHARMING Project, a project focusing on the education of current and future chemical industry stakeholders. This paper includes the design principles for a virtual reality training environment including the features that enhance the effectiveness of virtual reality training such as game-based learning elements, learning analytics, and assessment methods. This work can assist those interested in exploring the potential of virtual reality training environments in the chemical industry from a multidisciplinary perspective.
