Abstract X-Area is the uniquely versatile software suite connected to STOE single crystal diffractometers. Its abilities range from maintaining and steering the diffractometer itself to the reduction of measured data. In the following we will give a general overview of X-Area’s features and provide insight into specific software parts. For indexing and integration, X-Area offers in each case one program supporting more detailed configuration options and one application emphasizing automation. Furthermore, we will discuss the scaling and diagnosis tools available, which provide deeper insight into the collected X-ray data, therefore allowing for a better informed choice of data treatment. Everything is rounded off with an example of measurement results with a standard nickel salen crystal.

Ensuring security and comfort in public transportation is essential, particularly in the post-COVID-19 era. Passengers not only require reliable transit services but also expect sufficient space and healthy air quality for a safe travel experience. However, existing public transport systems lack realtime monitoring solutions for air quality and vehicle occupancy. This paper presents SenMooVe, a sensor platform designed for real-time air quality monitoring and passenger occupancy estimation in public vehicles. The platform consists of a Master unit for data acquisition and transmission, air quality sensors, and Ultra-wideband (UWB) radar sensors for passenger detection. Additionally, it integrates GPS signals for real-time vehicle tracking and interfaces with the Integrated Board Information System (IBIS) to access passenger information, stop locations, and schedule updates. It also monitors bus door status to enhance operational safety and efficiency. An initial experiment conducted in an suburban/rural environment collected 3,623 data samples over approximately 300 hours of operation. A preliminary correlation between air quality and passenger numbers has been established using data from an already integrated time-of-flight (ToF) based passenger counting system at bus doors. To facilitate further research and development, these datasets are made publicly available, providing valuable insights for transport operators, route planners, academic researchers, and public institutions. Future work will focus on developing a user-friendly visualization summary for real-time passenger information, enhancing situational awareness and ensuring a safer, more comfortable travel experience.

Abstract The HypoWave transdisciplinary research project investigated the innovation of water reuse in a hydroponic system, focusing on its applicability in Germany. The methods applied were the operation of a pilot plant for the appropriate treatment and subsequent reuse of water in a hydroponic system, expert interviews, feasibility studies, an impact assessment and a stakeholder dialogue. To identify the concept's advantages and disadvantages, publications specialising in the various disciplines involved and meeting protocols were analysed and the results grouped together in a SWOT (strengths, weaknesses, opportunities and threats) analysis. This revealed that the system has potential for application in Germany subject to certain requirements being met, such as suitable local wastewater treatment conditions and actors looking for new business opportunities within agricultural production. This system is not recommended for the country as a whole, but it does offer an interesting alternative for locations that meet the appropriate conditions. Nevertheless, additional efforts and knowledge are required to promote and operate a new system of this kind. These include the reliable supply of irrigation water with guaranteed plant nutrition, comprehensive quality management to manage potential risks, a good understanding of the cooperation arrangements required and a more detailed examination of energy aspects.

Research documents that even subtle changes in visible skin condition affect perceptions of age, health, and attractiveness. There is evidence that hair quality also affects the assessment of physical appearance, as variations in hair diameter, hair density, and hair style have systematic effects on perception. Here, we consider combined effects of hair color and skin color on the perception of female physical appearance. In two experiments, we digitally manipulated facial skin color of lightly-pigmented, young women, both between-subjects (Experiment 1) and within-subjects (Experiment 2), and investigated possible interactions with hair color in regard to age, health, and attractiveness perception. In both experiments, we detected hair color and skin color interaction effects on men's and women's assessments. For between-subjects comparisons, participants with lighter hair color were judged to be younger than those with darker shades; this effect was more pronounced in women with light skin color. No such effect was observed for within-subjects variation in skin color. Both experiments showed that smaller perceived contrast between hair color and skin color resulted in more positive responses. We conclude that hair color and facial skin color together have an effect on perceptions of female age, health, and attractiveness in young women, and we discuss these findings with reference to the literature on the role of hair and skin in the assessment of female physical appearance.

If accuracy matters, mechanical quantities such as force, torque or pressure are almost exclusively realized by transducers, which are based on strain gauges. To exploit the potential of static measurements the demands for amplifiers with an increased accuracy steadily grow. Unlike transducers, improvement of precision of amplifiers can go very far. Still these high-precision amplifiers can be realised I a very compact size. The new amplifier introduced features two independent (simultaneously measuring) amplifier channels, each of the channels offering an accuracy class of 0.0025 (25 ppm).
