Lichtkräfte auf einen Indiumatomstrahl
Klöter, Bernhard (2007)Die atomare Nanostrukturierung (atomic nanofabrication, ANF), d. h. das kontrollierte Abscheiden von Atomen auf einem Substrat bietet interessante Perspektiven, wenn zwei atomare Spezies benutzt werden. Besonders interessant ... -
LiDAR-Based Semantic Perception for Autonomous Vehicles
Chen, Xieyuanli (2022-09-08)Scene understanding is one of the fundamental building blocks that enable mobile systems to achieve autonomy. It is the process of perceiving, analyzing, and elaborating an interpretation of a 3D dynamic scene ob- served ... -

Blum, Ulrich Alois (2003)Since 1997 the Bonn University Institute of Physics operates a Rayleigh/Mie/Raman lidar on the Esrange near the Swedish city of Kiruna north of the Arctic circle. During seven winter and six summer campaigns a large amount ... -
Life cycle assessment of carbon and energy balances in Jatropha production systems of Burkina Faso
Baumert, Sophia Emilia (2014-05-12)Modern bioenergy offers several advantages to Burkina Faso, a country that is heavily dependent on imported fossil fuel and greatly relying on traditional biomass use. In this context, Jatropha curcas has been recently ... -
Life History and Mating Behaviour of the Scorpionfly Panorpa alpina Rambur (Mecoptera): Choice and Strategy = Lebensgeschichte und Paarungsverhalten der Skorpionsfliege Panorpa alpina Rambur (Mecoptera): Wahl und Strategie: With Remarks on the Methods of Causal Modeling = Mit Anmerkungen zu den Methoden der kausalen Modellierung
Bornemann, Gerhild (2013-05-07)Life history theory bases on the fundamental assumption that the behaviour of living things at any time of their lives aims at the maximisation of their reproductive success. The present thesis adopts this assumption, which ... -
Life, Thought and Image of Wang Zheng, a Confucian-Christian in Late Ming China
Ding, Ruizhong (2019-08-23)This dissertation aims at the core question, which is that Wang Zheng, as a Confucian literati with a classical Chinese tradition and education, how did he interpret the Christian teachings and set up his thought system? ... -
Lifelong Exposure to dietary Soy Isoflavones: Impact on Mammary Gland and Small Intestine of Female Rats
Molzberger, Almut Felizitas (2012-10-24)Introduction: The incidence of breast cancer in Eastern Asia is approximately 3-times lower than in western countries, and nutrition seems to play an important role. The traditional East Asian diet is rich in soy, which ... -
Ligandenfeldanalyse im Rahmen des Angular Overlap Model an einer Reihe von Samarium(III)-oxoverbindungen mit ergänzenden Betrachtungen zu Europium(III)-oxoverbindungen
Kannengießer, Nils (2022-10-17)Diese Arbeit stellt die Ligandenfeldanalyse von Samarium(III)- und Europium(III)-oxoverbindungen, sowie von Samarium(III)- und Europium(III)-fluorid vor. Die Ligandenfeldanalysen wurden im Rahmen des Angular Overlap Model ... -
Light Propagation in Digital Material Structures
Velinov, Zdravko (2019-03-26)Light takes many paths throughout the physical environment, defined by a multitude of interactions with matter, before reaching an imaging sensor or the human eye and thus forming the visual perception of the world. ... -
A light-dependent aptamer-photoreceptor system enables spatiotemporal control of RNA biochemistry
Weber, Anna Maria (2022-07-29)Light plays an important role in all kingdoms of life and regulates processes such as plant growth, flowering or vision in complex life forms. The growing field of optogenetics harnesses those properties by combining them ... -
Light-trapping and Superhydrophobic Plant Surfaces: Optimized Multifunctional Biomimetic Surfaces for Solar Cells
Schulte, Anna Julia (2012-09-21)In a process spanning over 400 millions years of evolution, plants have developed multifunctional surfaces that are highly adapted to environmental conditions. Nature provides several millions varieties of plant species ... -
Lignine aus Low-Input-Pflanzen: Einfluss von Biomasse, Vorbehandlung und Aufschlussparametern auf Struktur und Antioxidanz
Rumpf, Jessica (2023-10-31)Lignin ist ein aromatisches Biopolymer, das in den Zellwänden von Pflanzen vorkommt. Es ist hauptsächlich aus drei sogenannten Monolignolen (<em>p</em>-Hydroxyphenyl (H), Guajakol (G) und Syringol (S)) aufgebaut, die über ... -
Like Uber for Tractors?: How to strengthen the rural sharing economy in India and Africa
Daum, Thomas; Baumüller, Heike (2020-07)With even basic models costing 10.000 Euro, tractors are out of reach for most smallholder farmers. However, farmers do not need to own tractors in order to benefit from them. Following the idea of the sharing economy, ... -
Limbische Encephalitis: Stellenwert der konventionellen MRT in der Routinediagnostik
Khouri, David-Alexis Thomas (2021-11-03)Die konventionelle MRT spielt in der Diagnostik der Limbischen Encephalitis eine zentrale Rolle. Oftmals erscheint letztere jedoch unauffällig oder grenzwertig pathologisch in der konventionellen MRT. In diesem Zusammenhang ... -
The Limestone Ranges of the Fitzroy Basin, Western Australia: A Tropical Semi-Arid Karst
Jennings, Joseph Newell; Sweeting, Marjorie Mary (1963)Within the field of karst morphological studies, much attention has been given to the characterisation of the various karst styles and to the rates of limestone erosion, which relate to different climatic conditions. The ... -
Limitation of body mass of herbivores: Allometry of food quality and of digestive aspects
Steuer, Patrick (2010-10-13)That the length of digesta passage rate of large herbivores was influenced by the BM of the animal was discussed controversial in the past and recently. However, recent studies with increasing data sets show tendencies to ... -
