The aim of this work is to determine the properties of the Giese salt in order to arrive at a contemporary classification of the Giese salt in the group of Prussian blue compounds/iron(III) hexacyanidoferrate(II/III), sometimes AFe3+[Fe2+(CN) 6] xH2O, (A = K, Na, NH4). Furthermore, the synthesis of Prussian blue nanoparticles is investigated.

As part of this project, in addition to the regular physics lecture, a real escape room is being developed for students in the teaching building on the subject of physics, in which they can apply and test the knowledge they have learned in the lecture in a problem-oriented manner. For this purpose, the subject matter is packed into 10 small, creative puzzles that cover important topics from the fields of mechanics, electromagnetism, thermodynamics, waves and oscillations as well as optics.

As top predators, marine mammals are an important component of marine ecosystems. They are under increasing pressure from anthropogenic activities such as fisheries, offshore wind energy development, shipping traffic, etc. The survey and assessment of their populations and precise knowledge of their distribution patterns, habitat requirements and population trends are prerequisites for their effective protection and sensible protected area management.
Within the framework of this project, the collection of new data along the analysis of existing data sets will contribute significantly to the knowledge required for the consideration of fundamental ecological relationships and are of high scientific value. Habitat-based models are used to investigate which abiotic, biotic and anthropogenic factors fundamentally influence the occurrence and distribution of marine mammals. Population dynamics models will provide information on the influence of various stressors on the development of harbour porpoise populations. These models will provide simulations of future population trends assuming different pressures from anthropogenic stressors and can, thus, inform the development of adequate management measures. HABITATWal will also integrate the German contribution to the international SCANS-IV survey in summer 2002, when regionally coordinated visual surveys in the shelf and offshore waters of the European Atlantic will be conducted to generate robust abundance estimates for regularly occurring cetacean species. Detailed information on the acoustic and visual occurrence and density of minke whales and other cetacean species will be collected through a dedicated shipboard survey on the Dogger Bank and an annual monitoring will be developed. In addition, the expansion of the recording methods in large-scale monitoring is to be accompanied scientifically. This also includes a feasibility study on the possible addition of a passive-acoustic monitoring (PAM) network in the German North Sea.

The Eurasian otter (Lutra lutra) is a strictly protected species whose populations in Germany are recovering in some areas (Ackermann, 2013). In the 19th century, the otter still showed a nearly area-wide distribution throughout Europe. However, habitat destruction, pollution of water bodies, and heavy hunting of the otter, which was considered a "fishery pest,"" caused a severe decline of this species until the 1970s. Thus, the otter was considered almost extinct in Germany at that time. In Lower Saxony, only isolated occurrences were known in the southern heath. It is therefore on the red list of endangered species nationwide, including in the state of Lower Saxony. By revitalization measures of its habitats the otter could already spread out again in the eastern Lower Saxony nearly area-wide. In order to get a realistic overview of the number of otters in the area of the FFH area ""Lutter, Lachte, Aschau"", a standardized survey of the local population should be carried out. It is therefore the aim to carry out a targeted monitoring in the study area in addition to precise mapping methods and to draw conclusions on the occurrence and feeding behavior of otters occurring there with the help of food and genetic analyses. The study also includes the recording of existing management measures in fisheries management as well as new developments in this area. "

The increase in population densities of leads to conflicts of different actors in rural areas. In the future, forests in Lower Saxony will be transformed to cope with changing climatic conditions. High densities of cloven-hoofed game and especially local large pack formation can be detrimental to such regeneration of forest systems.

In this project, it will be discussed whether and for which reasons large packs are formed in cloven-hoofed game populations in Lower Saxony. For this purpose, the occurrence of wolves in different project areas will also be considered as a possible influencing factor.

In three subprojects:
The activity in space and time as well as population densities and abundances of roe deer, red deer and fallow deer will be determined.
Analyze the dietary components of wolves on the basis of loosening finds.
Trends in the occurrence of cloven-hoofed game and the opinion of hunters in the hunting grounds of Lower Saxony on possible influences will be presented with the help of wildlife surveys.

The aim of this work is to determine the bone density as well as the geometric structure of the upper and lower jaw bones in the vicinity of the molars. Horses of different ages are compared to find out whether differences in bone density and structure are the cause of the more common lower jaw complications in young horses.

Die Gesundheit von Pferden ist das wichtigste Ziel von Tiermedizin und Zucht. Allerdings werden Gesundheitsmerkmale bisher noch nicht auf wissenschaftlicher Forschungsgrundlage als Selektionskriterien in der Zucht genutzt. Um gezielte züchterische Maßnahmen zur Verbesserung der Pferdegesundheit ergreifen zu können, ist somit eine standardisierte Datenerhebung nötig. Diese solide Datenbasis soll in einer zentralen Gesundheitsdatenbank, welche seit 2014 von der Deutschen Reiterlichen Vereinigung e.V. (FN) in Planung ist, zusammengetragen werden und somit der Forschung als wissenschaftliche Grundlage dienen. Diese Dissertation konzentriert sich zwar auf die Köruntersuchungen, behält sich aber die Ausdehnung der Ergebnisse, vor allem des letzten Teils der Dissertation, auf alle weiteren Untersuchungen am Pferd, insbesondere der Kaufuntersuchungen, vor.
Im ersten Teil der Dissertation soll ein Status quo hinsichtlich der Untersuchungen der Köraspiranten erhoben werden, indem die verschiedenen Köruntersuchungsprotokolle der jeweiligen FN-Mitgliedsverbände verglichen werden und eine Vereinheitlichung versucht wird. Daraufhin werden in dem zweiten Teil, der retrospektiven Befunderhebung, die Daten der letzten Jahrgänge in die bereits bestehende Datenbank der Vereinigten Informationssysteme Tierhaltung w.V. (vit) eingepflegt. Anschließend folgt eine erste statistische Auswertung der Daten, welche u.a. hinsichtlich der insgesamt vorkommenden Befunde und Inzidenzen erörtert wird. Zuletzt soll als prospektive Originalarbeit in Form eines Fragebogens eine Strategie zur Optimierung der Datenweiterleitung der Tierärzte an die zentrale Gesundheitsdatenbank für Pferde erarbeitet werden.
Zusammengefasst sollen die Ergebnisse dieser Dissertation standardisierte Untersuchungen von Köraspiranten erzielen, eine gewisse Datenbasis in der zentralen Gesundheitsdatenbank für Pferde schaffen und zugleich eine optimierte Nutzung dieser bewirken.

Neue Erkenntnisse zeigen, dass die Mikrobiom-Darm-Hirn-Achse einen wichtigen Einfluss auf die Hirngesundheit haben kann. Ein Ungleichgewicht der Darmflora könnte unkontrollierbare Epilepsien begünstigen. In unserer Studie transplantieren wir geeignete Darmflora an Patienten, bei denen Antiepileptika nicht wirken.Während der Studie sammeln wir Kot, Urin und Speichel und testen Anfallsfrequenz und Verhaltensaspekte der Hunde.
