Ergonomics principles help designing the workplace in a way that makes work more efficient and safer. Employee satisfaction increasingly affects the productivity of a process, which also includes disabled people and represents an important source of human resources. In the framework of the EU-project ERGO WORK a survey-based research was conducted to measure the satisfaction of people with disabilities (PWD) in their workplace and asses how their satisfaction was perceived by employers in UK, Poland and Slovenia. Three hundred and three respondents were involved in the survey. Results show that PWD place a great emphasis on the satisfaction in the workplace. PWD in Slovenia are more satisfied than PWD in Poland, whereas the employers' perception of the satisfaction of PWD and other employees in Poland, Slovenia and UK does not vary. A general adaptation of the workplace significantly and positively influences the satisfaction of persons with disability and that the adaptation of the workplace to the needs of PWD is better if employers have access to knowledge, special equipment and financial resources.
The saponification of ethyl acetate was measured by conductimetry at different temperatures within a batch reactor. A new mathematical model for obtaining concentration profiles from conductivity was presented and used for reaction-kinetics' determination. The Arrhenius parameters (A, E a ) showed good agreement with the previously published values. Basic transition-state theory was used for obtaining the Gibbs energy ( G ‡ ), the enthalpy ( H ‡ ), and the entropy ( S ‡ ) of activation. The low enthalpy of activation and negative entropy of activation were consistent with a reaction pathway when forming a transition-state complex. The suggested mechanism involves OH − , acting as a general base for removing proton from one of the hydroxide hydrating water, placed directly between it and the ester. The nucleophile from the water then attacks at the electrophilic C of the ester, breaking the π bond, and creating a tetrahedral intermediate. C
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
