Abstract
Purpose
The purpose of this paper is to describe an electro-mechanical lumped parameters model used for the simulation of an energy harvester device.
Design/methodology/approach
The model is taking into account the main features of both mechanical and electromagnetic phenomena keeping the computational burden as low as possible to insert it inside an optimisation loop.
Findings
The simulation tool is then used to design the main parameters of an energy harvester able to supply a computer mouse by converting mechanical energy provided by the computer user.
Originality/value
The use of a multi-physics analysis tool inside one optimisation loop is a difficult task that requires the honing of all the modules involved in the performance evaluation. The developed approach has shown to be reliable, efficient and has been a key factor in the development of a new product.

Abstract
Purpose
The purpose of this paper is to critically summarize the current data concerning the impact of obesity and micronutrient adequacy and supplementation on the risk and severity of COVID-19 disease, and their potential impact on treatment and rehabilitation.
Design/methodology/approach
PubMed, Scopus and Google Scholar databases were thoroughly searched to identify studies concerning obesity and nutritional status, vitamin and other micronutrients adequacy with COVID-19 severity.
Findings
Individuals with higher body mass index are in greater risk of severe disease and need for mechanical ventilation. Concerning micronutrient adequacy, no published studies at the present time have evaluated the effect of supplementation on the risk and the treatment of the novel disease.
Originality/value
Recently, COVID-19 has monopolized the interest of the medical community regarding diet and nutritional status and it possibly plays an important role in disease severity.
