These are inter alia volatile prices for relevant input factors, uncertainties concerning the regulation of CO₂-emissions and market shocks caused by the recently introduced additional import duties in the US, which is an important sales market. We examine primary and secondary effects of these challenges on the steel industry in the EU and their impacts on European and global level. Developing and using a suitable meta-model, we analyze the competitiveness of key steel producing countries with respect to floor prices depending on selected cost factors and draw conclusions on the impacts in the trade of steel on emissions, energy demand, on the involvement of developing countries in the value chain as well on the need for innovations to avoid relocations of production. Hence, our study contributes to the assessment of sustainable industrial development, which is aimed by the Sustainability Development Goal "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation countries". By applying information on country-specific Human Development Indexes (reflecting aspects of life expectancy, education, and per capita income), we show that relocating energy-intensive industries from the EU may not only increase global energy demand and CO₂-emissions, but may also be to the disadvantage of developing countries.}, language = {en} } @article{VoegeleJosyabhatlaBalletal.2023, author = {V{\"o}gele, Stefan and Josyabhatla, Vishnu Teja and Ball, Christopher and Rhoden, Imke and Grajewski, Matthias and R{\"u}bbelke, Dirk and Kuckshinrichs, Wilhelm}, title = {Robust assessment of energy scenarios from stakeholders' perspectives}, series = {Energy}, journal = {Energy}, number = {In Press, Article 128326}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1873-6785 (Online)}, doi = {10.1016/j.energy.2023.128326}, year = {2023}, abstract = {Using scenarios is vital in identifying and specifying measures for successfully transforming the energy system.

In particular, there are uncertainties about how to deal with modifications in the scenarios. In principle, new consulting processes will be required. In our study, we show how multi-criteria decision analysis can be used to analyze stakeholders' attitudes toward transition paths. Since stakeholders differ regarding their preferences and time horizons, we employ a multi-criteria decision analysis approach to identify which stakeholders will support or oppose a transition path. We provide a flexible template for analyzing stakeholder preferences toward transition paths. This flexibility comes from the fact that our multi-criteria decision aid-based approach does not involve intensive empirical work with stakeholders. Instead, it involves subjecting assumptions to robustness analysis, which can help identify options to influence stakeholders' attitudes toward transitions.}, language = {en} } @article{VoegeleRuebbelkeGovorukhaetal.2019, author = {V{\"o}gele, Stefan and R{\"u}bbelke, Dirk and Govorukha, Kristina and Grajewski, Matthias}, title = {Socio-technical scenarios for energy-intensive industries: the future of steel production in Germany}, series = {Climatic Change}, journal = {Climatic Change}, publisher = {Springer}, address = {Berlin}, issn = {0165-0009}, doi = {10.1007/s10584-019-02366-0}, pages = {1 -- 16}, year = {2019}, language = {en} } @article{WagnerDollSchoening2014, author = {Wagner, Patrick and Doll, Theodor and Sch{\"o}ning, Michael Josef}, title = {Engineering of functional interfaces / Patrick Wagner ; Theodor Doll ; Michael J.

Different external magnetic fields can be adjusted to move the magnetic beads loaded with a specific drug within the measurement cell.

This work represents a new flexible approach to read out light-addressable potentiometric sensors (LAPS) with the help of a digital light processing (DLP) set-up. The DLP, known well for video projectors, consists of a mirror-array MEMS device, which allows fast and flexible generation of light patterns. With the help of these light patterns, the sensor surface of the LAPS device can be addressed. The DLP approach has several advantages compared to conventional LAPS set-ups, e.g., the spot size and the shape of the light pointer can be changed easily and no mechanical movement is necessary, which reduces the size of the set-up and increases the stability and speed of the measurement. In addition, the modulation frequency and intensity of the light beam are important parameters of the LAPS set-up. Within this work, the authors will discuss two different ways of light modulation by the DLP set-up, investigate the influence of different modulation frequencies and different light intensities as well as demonstrate the scanning capabilities of the new set-up by pH mapping on the sensor surface.}, language = {en} } @article{WagnerWernerMiyamotoetal.2011, author = {Wagner, Torsten and Werner, Frederik and Miyamoto, Ko-Ichiro and Sch{\"o}ning, Michael Josef and Yoshinobu, Tatsuo}, title = {A high-density multi-point LAPS set-up using a VCSEL array and FPGA control}, series = {Sensors and Actuators B: Chemical. 154 (2011), H. 2}, journal = {Sensors and Actuators B: Chemical. 154 (2011), H. 2}, publisher = {Elsevier}, address = {Amsterdam}, isbn = {1873-3077}, pages = {124 -- 128}, year = {2011}, language = {en} } @inproceedings{WagnerYoshinobuOttoetal.2006, author = {Wagner, Torsten and Yoshinobu, T. and Otto, R. and Rao, C. and Molina, R. and Sch{\"o}ning, Michael Josef}, title = {Licht-adressierbare potentiometrische Sensorsysteme - Konzepte und Anwendungen}, series = {Sensoren und Mess-Systeme 2006 : Vortr{\"a}ge der 13.

Comparisons were made between movement modalities executed in hypergravity (1.8 G) and gravity on ground (1 G). In 1.8 G, ankle dorsiflexion, knee joint flexion, and vertical center of mass (COM) displacement are lower in DJs than in DLs; within each movement modality, joint flexion amplitudes and COM displacement demonstrate higher values in 1.8 G than in 1 G. Concomitantly, negative peak ankle joint power, vertical ground reaction forces, and leg stiffness are similar between both movement modalities (1.8 G). In DJs, EMG activity in 1.8 G is lower during the COM deceleration phase than in 1 G, thus impairing quasi-isometric fascicle behavior. In DLs, EMG activity before and during the COM deceleration phase is higher, and fascicles are stretched less in 1.8 G than in 1 G. Compared with the situation in 1 G, highly task-specific neuromuscular activity is diminished in 1.8 G, resulting in fascicle lengthening in both movement modalities. Specifically, in DJs, a high magnitude of neuromuscular activity is impaired, resulting in altered energy storage. In contrast, in DLs, linear stiffening of the system due to higher neuromuscular activity combined with lower fascicle stretch enhances the buffering function of the tendon, and thus the capacity to safely dissipate energy.}, language = {en} } @article{WaldvogelRitzmannFreyleretal.2021, author = {Waldvogel, Janice and Ritzmann, Ramona and Freyler, Kathrin and Helm, Michael and Monti, Elena and Albracht, Kirsten and St{\"a}udle, Benjamin and Gollhofer, Albert and Narici, Marco}, title = {The Anticipation of Gravity in Human Ballistic Movement}, series = {Frontiers in Physiology}, journal = {Frontiers in Physiology}, publisher = {Frontiers}, address = {Lausanne}, issn = {1664-042X}, doi = {10.3389/fphys.2021.614060}, year = {2021}, abstract = {Stretch-shortening type actions are characterized by lengthening of the pre-activated muscle-tendon unit (MTU) in the eccentric phase immediately followed by muscle shortening. Under 1 g, pre-activity before and muscle activity after ground contact, scale muscle stiffness, which is crucial for the recoil properties of the MTU in the subsequent push-off. This study aimed to examine the neuro-mechanical coupling of the stretch-shortening cycle in response to gravity levels ranging from 0.1 to 2 g. During parabolic flights, 17 subjects performed drop jumps while electromyography (EMG) of the lower limb muscles was combined with ultrasound images of the gastrocnemius medialis, 2D kinematics and kinetics to depict changes in energy management and performance. Neuro-mechanical coupling in 1 g was characterized by high magnitudes of pre-activity and eccentric muscle activity allowing an isometric muscle behavior during ground contact. EMG during pre-activity and the concentric phase systematically increased from 0.1 to 1 g. Below 1 g the EMG in the eccentric phase was diminished, leading to muscle lengthening and reduced MTU stretches. Kinetic energy at take-off and performance were decreased compared to 1 g. Above 1 g, reduced EMG in the eccentric phase was accompanied by large MTU and muscle stretch, increased joint flexion amplitudes, energy loss and reduced performance. The energy outcome function established by linear mixed model reveals that the central nervous system regulates the extensor muscles phase- and load-specifically. In conclusion, neuro-mechanical coupling appears to be optimized in 1 g. Below 1 g, the energy outcome is compromised by reduced muscle stiffness. Above 1 g, loading progressively induces muscle lengthening, thus facilitating energy dissipation.}, language = {en} } @misc{WandreyBiselliSchroederetal.1999, author = {Wandrey, Christian and Biselli, Manfred and Schr{\"o}der, Bernd and Schmoll, Hans-Joachim}, title = {Culturing cells on macroporous glass carriers coated with gelatin, extracellular matrix protein and stromal cells}, pages = {1 -- 12}, year = {1999}, language = {en} } @article{WangKrauseBlocketal.2003, author = {Wang, J. and Krause, R. and Block, K. and Musameh, M. and Mulchandani, A. and Sch{\"o}ning, Michael Josef}, title = {Flow injection amperometric detection of OP nerve agents based on organophosphorus-hydrolase biosensor detector}, series = {Biosensors \& Bioelectronics. 18 (2003), H. 2-3}, journal = {Biosensors \& Bioelectronics. 18 (2003), H. 2-3}, isbn = {0956-5663}, pages = {255 -- 260}, year = {2003}, language = {en} } @article{WarerkarSchmitzGoettscheetal.2011, author = {Warerkar, Shashikant and Schmitz, Stefan and G{\"o}ttsche, Joachim and Hoffschmidt, Bernhard and Reißel, Martin and Tamme, Rainer}, title = {Air-Sand Heat Exchanger for High-Temperature Storage}, series = {Journal of Solar Energy Engineering. 133 (2011), H. 2}, journal = {Journal of Solar Energy Engineering. 133 (2011), H. 2}, publisher = {ASME}, address = {New York}, isbn = {0199-6231}, pages = {021010}, year = {2011}, language = {en} } @article{WarmerWagnerSchoeningetal.2015, author = {Warmer, Johannes and Wagner, Patrick and Sch{\"o}ning, Michael Josef and Kaul, Peter}, title = {Detection of triacetone triperoxide using temperature cycled metal-oxide semiconductor gas sensors}, series = {Physica status solidi (a)}, volume = {212}, journal = {Physica status solidi (a)}, number = {6}, publisher = {Wiley-VCH}, address = {Weinheim}, issn = {1862-6319}, doi = {10.1002/pssa.201431882}, pages = {1289 -- 1298}, year = {2015}, language = {en} } @book{Weber1982, author = {Weber, Hans-Joachim}, title = {In-vivo-Untersuchungen am Experimentaltumor Sarkom 180 {\"u}ber die Therapieeffizienz von Gammastrahlen und Neutronen in Verbindung mit Hyperthermie und Misonidazol}, pages = {76, [22] S. : Ill., graph.
