from the article: Supply chain integration intensifies through digitalisation of business administration (BA) processes. However, it is unclear whether differences exist between the public and private sector in development or implementation of supply chain integration solutions. The large scope of the supply chain, being a large network of companies working together towards one end product, is limited for this study to e-procurement processes. The related software solutions are included. This study starts with a theoretical snapshot of e-procurement. This is followed by a process viewpoint of the e-procurement function. Next five different forms of e-procurement cooperation are presented seen from an actors network viewpoint. The utilisation of these forms create insight in the differences between the public and private sector in their e-procurement adoption behaviour. The process maturity scan results shows that the process maturity between the two sectors is comparable. However, this only explains the differences per sector concerning their ability to improve and control their processes in general. For reliability, this step is followed by three in-depth interviews combined with analyses of recent e-procurement behaviour studies involving the two sectors. The final step compares the maturity outcome with the in-depth data results. Both sectors show certain forms of coalition in the e-procurement. Where ‘competition’ is a construct that drives the private sector, the public sector has cost control as a driver towards collaboration and integration within e-procurement. This can only partially be explained by the past European financial crises. Differences are found in digital collaboration and the integration itself. The most important difference lies in the European tendering procedure to which the public sector (unlike the private) is restricted. In nature an e-procurement design and development project does not fit the prescribed procedures.
Background: Everyday exposure to radiofrequency electromagnetic fields (RF-EMF) emitted from wireless devices such as mobile phones and base stations, radio and television transmitters is ubiquitous. Some people attribute non-specific physical symptoms (NSPS) such as headache and fatigue to exposure to RF-EMF. Most previous laboratory studies or studies that analyzed populations at a group level did not find evidence of an association between RF-EMF exposure and NSPS. Objectives: We explored the association between exposure to RF-EMF in daily life and the occurrence of NSPS in individual self-declared electro hypersensitive persons using body worn exposimeters and electronic diaries. Methods: We selected seven individuals who attributed their NSPS to RF-EMF exposure. The level of and variability in personal RF-EMF exposure and NSPS were determined during a three-week period. Data were analyzed using timeseries analysis in which exposure as measured and recorded in the diary was correlated with NSPS. Results: We found statistically significant correlations between perceived and actual exposure to wireless internet (WiFi - rate of change and number of peaks above threshold) and base stations for mobile telecommunications (GSM+UMTS downlink, rate of change) and NSPS scores in four of the seven participants. In two persons a higher EMF exposure was associated with higher symptom scores, and in two other persons it was associated with lower scores. Remarkably, we found no significant correlations between NSPS and timeweighted average power density, the most commonly used exposure metric. Conclusions: RF-EMFexposure was associated either positively or negatively with NSP Sinsome but not all of the selected self-declared electro hypersensitive persons. https://doi.org/10.1016/j.envint.2018.08.064

Initial investigations into the use of a MEMS based multi-parameter sensor for the characterization of medicine mixtures are presented. The current results show good results for density and mediocre results for heat capacity. Viscosity measurements have not yet produced any usable results. However there are clear flaws in the setup which could be the cause of this and which will no
