Neonicotinoid insecticides impair foraging behavior, navigation, learning, and memory in honey bees (Apis mellifera)

Léa Tison
The decline of pollinators worldwide is of growing concern because of the essential role they have in our ecosystem, agriculture and economy. Both biotic and abiotic factors have been implicated as possible contributors to their decline; however, the potential role(s) of commonly-used neonicotinoid insecticides has emerged as particularly concerning in the last decade. I chose to focus my research on two substances: thiacloprid, a widely used cyano-substituted neonicotinoid thought to be less toxic to honey...

Die islamische Bewegung der Hamas in Palästina

Bassam Ewaida
Zusammenfassung Zum ersten Mal hat die fundamentalistische Hamas-Bewegung bei den Parlamentswahlen in den palästinensischen Gebieten vom 25.01.2006 geschafft, die Macht durch demokratische Wahlen zu erringen. Als Wurzel der Hamas gilt die Weiterentwicklung der Muslimbrüder aus Ägypten, die der Scheich Hassan Al-Banna4 1928 gegründet hat. Durch die palästinensischen Studenten, die an den ägyptischen Universitäten studiert haben, ist die Hamas in den Gaza-Streifen gelangt. Die Aktivitäten der Muslimbrüder in Palästina begannen mit der Errichtung des Staates Israel...

Trictide, a Tricellulin-Derived Peptide to Modulate Cell Barriers and to Understand the Tricellular Organization of Tight Junctions

Başak Arslan
Tricellulin (Tric) is a tight junction protein at tricellular contacts; however its exact structure, function and regulation are unclear. Tric contributes to the paracellular tightening by intercellular trans-interactions between its extracellular loops 2 (ECL2). Consequently, trictide, a peptide derived from the Tric ECL2 was designed as a potential drug enhancer to specifically overcome tissue barriers. This work is aimed to investigate the functional and molecular modulations of tricellular contacts caused by trictide and to understand...

Quantitative Studies on European Economic Integration Between 1880 and 1939

Hans Christian Heinemeyer
My thesis analyzes various types of economic integration over about half a century. It consists of four parts. Chapter 2 strives to separate the ‘treatment effect’ of national border demarcation. Earlier research into prices and trade has presented robust evidence that political borders divert trade beyond explicit border costs. Price data show that political borders correlate with deviations from the law of one price. Trade data indicate lower than expected exchange of goods across borders....

Charakterisierung einer potentiellen Rolle des Nicht-Strukturproteins (NS) 1 der Influenza A Viren im viralen mRNA Export

Melanie Franz
Influenza Viren verfolgen eine nukleare Replikationsstrategie und benötigen für ihre Vermehrung Komponenten der zellulären RNA-Prozessierungsmaschinerie. Die Transkription viraler mRNAs erfolgt durch den viralen Polymerase Komplex. Nur zwei der zehn viralen Transkripte werden gespleißt und könnten durch eine Assoziation mit dem zellulären Spleißapparat auf gleiche Weise Zugang zu Exportfaktoren erhalten, wie die zumeist intronhaltigen zellulären mRNAs. Die meisten viralen mRNAs hingegen werden nicht gespleißt und werden daher per se nur ineffizient von der nuklearen Exportmaschinerie erkannt....

Robust Efficiency of Airline Resource Schedules

Lucian Ionescu
During operations, airlines frequently have to deal with disruptions, causing a gap between expected planned costs and real operational costs for the resource deployment. This issue is addressed by the concept of robust efficiency: While maintaining its planned cost efficiency as well as possible, the robustness of a schedule against the impact of unforeseeable delays is improved. There are two eligible schedule properties that affect the robustness, namely stability and flexibility. While stability refers to...

The Impact of Educational Attainment and Grade Retention on the Development of Intelligence

Daniela Sangme Schalke-Mandoux
European countries are faced with a demographic change. People are living longer than ever before, while, at the same time, birth rates are below replacements levels. Thus, European countries will have to deal with an increasingly aging labor market as well as a growing amount of elderly people in need of care. Healthy cognitive aging is important for both of these challenges in Europe (Ball et al., 2002; European Commission, 2014). Thus, investing in healthy...

Scattering of an X-Ray beam on a Surface Acoustic Wave

Simone Vadilonga
In this work surface acoustic waves (SAWs) are studied as a tool to manipulate spa- tially and temporally an X-ray beam. SAWs have been intensively studied in the last decades, and X-ray diffraction proved to be a useful tool to investigate the propa- gation of a SAW in different materials. A SAW induces a sinusoidal deformation on the substrate surface, which acts as a grating when illuminated by X-rays pro- ducing diffraction satellites. Their intensity...

Einflussfaktoren auf die Trächtigkeit bei Vollblutstuten nach Kolikoperationen

Niklas Julius Drumm
Fast immer erzeugt eine Kolik der trächtigen Stute nicht nur Sorge um die Stute, sondern auch um die Frucht. Die Fohlenraten für Stuten, die während der Trächtigkeit wegen Kolik behandelt werden mussten, schwankten in verschiedenen Studien zwischen 53,8 und 80 % (BOENING u. LEENDERTSE, 1993; CHENIER u. WHITEHEAD, 2009; SANTSCHI et al., 1991). Die augenscheinlichste Erkenntnis war, dass Stuten, welchen konservativ geholfen werden konnte, eine niedrigere Abortrate als Stuten nach Operationen hatten. Verschiedene mögliche Einflussfaktoren...
