... The most common post-processing steps, after the essential cleaning of parts from the leftover powder and cutting the products from the building platforms, include heat treatment, for stress relieving and hardening. The parts can also be subjected to shot-peening to slightly smooth the surfaces, different milling steps (using a computer numerical controlled machine, CNC) and polishing if dimensional requirements are tight and surface quality is required [47,48,49]. ...
... It has been found that an accumulation of proline occurs in plants under different abiotic stress factors, including oxidative stress (Yang et al., 2009), gamma irradiation (Jan et al., 2012), heavy metals (Bao et al., 2011), high light and UV irradiation (Saradhi et al., 1995), waterlogging (Xu et al., 2012), chilling (Luo et al., 2011, high salinity (Sripinyowanich et al., 2013), and deficit water stress (Saeedipour, 2013). Studies investigating resistivity and susceptibility of plants to abiotic stress have demonstrated the fundamental importance of proline in tolerance (Saiema et al., 2012;Saeedipour, 2013). ...
... Sector or domain independence means that the artefact is not specific to a sector/domain [81,82]. Achieving this requirement facilitates capture, transfer, and reuse of domain knowledge from different domains [83]. Neither POCM nor Onto-RPD requires practitioners to be familiar with the sector or domain in which a recruitment practice is applied. ...

... Using micro data from 2001, Akiyoshi & Ono (2008) compared and contrasted the determinants of mobile versus computer-based internet in Japan, findings showed that mobile internet access, as compared to computer access, was determined less by demographics, socioeconomic status, and technological readiness. Through a regression analysis of 106 observations, Lee, et al.,(2007 found that multiple standardization policy, lower level of 1G and 2G penetration, and a higher level of income contribute to the diffusion of 3G mobile. Employing a logistic diffusion model, Lee, et al., (2011) analyzed the factors that influence the diffusion of fixed and mobile broadband, and found that for mobile broadband, multiple standardization policy and population density were the main factors of the initial diffusion of mobile broadband services. ...
