1. 1. Increasing the diodicity of ceramic Tesla valves by exploiting the design freedom of additive manufacturing : A study in design optimizations of Tesla valves for ceramic 3D printing

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Udit Sharma; [2024]
   Keywords : additive; manufacturing; Tesla; valve; ceramic; 3D; printing;

   Abstract : The work presented in this thesis was conducted at Uppsala University and at Fraunhofer IKTS, Dresden. The thesis aims to study design optimizations for increasing the diodicity and thereby performance of a Tesla valve, a type of “no moving parts” (NMP) valve, through design freedoms offered by ceramic additive manufacturing.

4. 3. THE CHOSEN CREATURES: HOW ANIMAL JUXTAPOSITIONS IN ANTISEMITIC PROPAGANDA CONTRIBUTED TO INSTITUTIONALIZED OTHERNESS

   University essay from Göteborgs universitet/Institutionen för filosofi, lingvistik och vetenskapsteori

   Author : Heidi Keller; [2023-07-06]
   Keywords : ;

   Abstract : This paper discusses how anthropomorphic animals have been used in depicting Jews in antisemitic art and propaganda imagery since the late High Middle Ages until the first half of the 20th century. It sheds light on why certain animal species were chosen to symbolize Jews, and categorizes the animals into three groups: creatures taken from the Hebrew Scriptures and the Jewish folklore inspired by it, animals presented in secular and pagan folklore influenced by legends from Ancient Greece and Rome, and the “anti-charismatic” fauna.
