Dimensional accuracy is a highly important quality criterion for injection molded parts and due to the decreasing tolerance criteria an ongoing issue for mold makers, part designers and manufacturers. Variations in the molding process regarding temperature, pressure and thus the specific volume are leading to inner stress distributions within the part, which ultimately cause warpage. To reduce warpage, a homogenization of the local melt properties, such as the temperature, cooling rate or specific volume is necessary. To be able to manipulate these melt properties locally, a mold with a highly segmented temperature control, consisting of 18 heating ceramics and carbon dioxide expansion chambers was designed. This work seeks to reduce warpage using a newly developed control loop that adjusts target values for the upcoming molding cycle while considering the control error of the previous cycle. The self‐optimizing control loop‐ aiming to homogenize the local mold temperatures over multiple cycles‐ was evaluated in experimental trials. Test specimens were produced, and measured for warpage. Compared to the reference (no control), the warpage of a plate‐shaped geometry was reduced by 10 % with the mold temperature homogenization approach. [ABSTRACT FROM AUTHOR]

(Im)perfekte Körper 2.0 – Körperverständnisse in Körperpraktiken der Gegenwart In Körperpraktiken werden gesellschaftliche Körperverständnisse und -diskurse sichtbar. Es wird angenommen, dass Körperverständnisse im Zuge der gesellschaftlichen Transformation einem Wandel unterworfen sind. Der Beitrag geht der Frage nach, welche Körperverständnisse und Diskurse in zeitgenössischen, jugendlichen Körperpraktiken propagiert werden und ob ein Wandel im Körperverständnis bevorsteht.

Start-ups are considered to be ideally agile and serve as a model for restructuring in companies. The grounded theory study reconstructs how stress and strain are dealt with in agileorganized start-ups. Optimized stress management characterizes the work, which is determined by a wide range of tasks, tight time cycles and a pronounced commitment. Balancing the loads and appropriating the stress enables high performance but carries the risk of various negative stress experiences. There is the threat of getting lost in a tunnel, of experiencing dissonance due to contradictions between the experienced reality of the working conditions and the ideal of agility or of not being able to survive in the agile environment. The striving for balance, which is reflected in the wishes of the employees as well as in the conceptual principles of the agile workingmethod, thus appears fragile. Through different narratives the stress experiences get integrated into the optimized stress management. [ABSTRACT FROM AUTHOR]

Adolescence and the obsession with beauty The culture of perfecting the body: between demand and reality The demand for beauty and bodily perfection presents an increasing challenge for today's adolescents. New developments in media and technology play an important role in how today's adolescents evaluate themselves. A survey of 730 young people showed that one third of the adolescents were dissatisfied with their physical appearance and experienced social pressure from their parents and peers concerning their appearance. With reference to case material from two patients, we discuss the psychodynamics of this issue, including the development of a low self-esteem, social retreat and a basic sense of insufficiency. In order to develop a stable identity, these adolescents seem in urgent need of a personal narrative in which they can make their own decisions and find their own opinions in a self-assertive stance that counters the pressure from social media and social norms.

The power of the Cloud has been harnessed for pharmaceutical compound production with remote servers based in Tokyo, Japan being left to autonomously find optimal synthesis conditions for three active pharmaceutical ingredients (APIs) in laboratories in Cambridge, UK. A researcher located in Los Angeles, USA controlled the entire process via an internet connection. The constituent synthetic steps for Tramadol, Lidocaine, and Bupropion were thus optimized with minimal intervention from operators within hours, yielding conditions satisfying customizable evaluation functions for all examples.

This essay develops in three steps: First, the phenomenon of self-optimization is portrayed, with special focus on its manifestations in plastic surgery, neuroenhancement and medial self-staging. In the second part, a theological reflection of the topic is given. Questions about the self as a construct, the freedom of will of humans and the relation between happiness and self-optimization is applied to the topic. The reformation doctrine of sin and the categories of "law and gospel" will also be considered. In a third step, the subject is discussed against the background of religious education focusing on the term of grace through the topic of selfoptimization. [ABSTRACT FROM AUTHOR]
