This research estimates the shared value created by constructing a hypothetical Hyperloop to transport cargo along 300 km in Northern Germany. Following Porter and Kramer (2011, 2012), we identified and evaluated eight factors that create shared value: travel speed, operating costs, safety, noise pollution, air pollution, climate effect/ carbon footprint, separation effect/property efficiency, and maintenance. Using official data compiled by several German institutes and organizations, we conducted comparative analysis to quantify and compare the above-mentioned factors for Hyperloop and over-the-road cargo transport in Germany. Then, we monetized the individual and collective benefits of the shared value created by Hyperloop replacing a significant share of cargo transported by truck. Our findings indicate that the hypothetical Hyperloop project in Northern Germany would create €660-€900 million of shared value annually. Our research method establishes a framework for assessing future transportation projects, such as Hyperloop, and our findings can be generalized to industrialized nations beyond Germany.

BackgroundSince SLE tends to occur during the productive years of life, the cost of the disease derives not only from direct health expenditures but also from the impact the disease has on work productivity.ObjectivesTo describe the impact of SLE on work productivity and to assess the factors influencing this outcome measure.MethodsWe studied 225 patients (1987 ACR criteria), age ≥16 years. Work productivity was assessed with the WPAI:Specific Health Problem for SLE. The WPAI yeilds four scores: % work time missed, % of impairment at work, % of overall work impairment and % of non-work related activity impairment. The relationship between socioeconomic-demographic, self-reported quality of life (as per the Lupus PRO), clinical data [clinical manifestations, diagnostic criteria (1987 ACR criteria), disease activity (SELENA-SLEDAI), damage (SLICC Damage Index), co-morbidities (Charlson Index)] and the four scores of the WPAI was examined with the Man-Whitney U test and Spearman's Rho test. Variables with p≤0.10 in these analyses were then entered in a multivariable linear regression with each score of the WPAI as the dependent variable.ResultsPatients were predominantly females (89%) and they had a median (IQR) age at diagnosis of 26.0 (16.0) years. Median (IQR) disease duration was 96.0 (144.0) months. Median (IQR) percentage of work time missed was 0.0 (25.0)%, of impairment at work was 10.0 (56.0)%, of overall work impairment 0.0 (56.0)% and of activity impairment 40.0 (60.0)%. Variables significant in both, the univariable and multivariable analyses, are shown in Table belowConclusionsWhile work productivity is not largely affected in this sample of patients, non-work related activities seems to have a much greater impact in SLE. Patients with a higher disease activity and number of co-morbidities and a lower self-perceived quality of life are at higher risk for work productivity impairmentDisclosure of InterestNone declared

Die vorliegende Untersuchung konnte nur an einer Aluminiumprobe einige Aufklärung bringen. Es dürfte erforderlich sein, die Untersuchung insbesondere auf solches Aluminium auszudehnen, welches möglichst frei von mikroskopischen Beimengungen ist. Das Ergebnis läßt sich kurz, wie folgt, zusammenfassen: Durch Glühen und nachträgliches Abschrecken wird die Säurefestigkeit vom technischen Aluminium verbessert. Ein zu hohes Glühen wirkt schädlich. Der Verlauf der Grenzkurve der Al‐reichen Al‐Si‐Mischkristalle wird diskutiert. Durch Anlassen wird die Widerstandsfähigkeit des Aluminiums gegen Säureangriff infolge Zerfalls des Mischkristalls erhöht. Die Geschwindigkeit des Zerfalls ist bei 300° verhältnismäßig groß, bei 200° geringer und bei 100° selbst nach 168 stündigem Anlassen nicht mit Sicherheit nachzuweisen.
