Forest diversity in fragmented landscapes of northern Ethiopia and implications for conservation
Betemariam, Ermias Aynekulu (2011-04-21)Deforestation and habitat fragmentation that arise largely due to the conversion of forests to other agricultural land-use types and over-utilization of forest resources to satisfy the food and energy requirements of the ... -
Forest fragmentation and plant-pollinator interactions in Western Kenya
Bergsdorf, Thomas (2006)Rain forest fragmentation can affect plant-pollinator interactions and the reproductive success of plant species. Understanding these consequences is a crucial component of conserving vulnerable ecosystems. <br /> In this ... -
The forgotten agriculture-nutrition link: Estimating the energy requirements of different farming technologies in rural Zambia with time-use data
Daum, Thomas; Capezzone, Filippo; Birner, Regina (2019-08)In the quest to reduce global under- and malnutrition, which is particularly high among smallholder farmers, agriculture-nutrition linkages have received a lot of attention in recent years. Researchers have analysed the ... -
The Forgotten Agriculture-Nutrition Link: Estimating the energy requirements of different farming technologies in rural Zambia
Heni, Jakob; Daum, Thomas; Capezzone, Filippo; Birner, Regina (2020-03)Worldwide, 821 million people do not have access to enough calories, they are undernourished. In addition, close to two billion people lack micronutrients, they are malnourished and suffer from hidden hunger. Smallholder ... -
Formale semantische Modellierung von geomorphologischen Objekten und Prozessen des Hochgebirges zur Repräsentation in einem Geoinformationssystem (GIS)
Löwner, Marc-O. (2008)Die vorliegende Arbeit ist im Graduiertenkolleg “Das Relief- eine strukturierte und veränderliche Grenzfläche" an der Universität Bonn entstanden. Sie befasst sich mit der formalen semantischen Modellierung und geometrischen ... -
Formalisierung kartographischen Wissens zur Schriftplazierung in topographischen Karten
Ellsiepen, Matthias (2002)Schrift ist als Ausdrucksmittel in Karten unverzichtbar. Sie ermöglicht die Übermittlung von Informationen, die durch die Geometrie der Kartenobjekte nicht ausgedrückt werden können. In ihrer Funktion dient die Schrift ... -
A formalism for a consistent treatment of two-pion interactions in heavy meson decays
Ropertz, Stefan (2020-10-14)The best-established theory of particle physics up to now is the Standard Model. The theory of strong interactions called quantum chromodynamics (QCD) is a part of it. QCD leads to a wide range of phenomena, which still ... -
Formalization and Detection of Host-Based Code Injection Attacks in the Context of Malware
Barabosch, Thomas Felix (2018-10-31)The Host-Based Code Injection Attack (HBCIAs) is a technique that malicious software utilizes in order to avoid detection or steal sensitive information. In a nutshell, this is a local attack where code is injected across ... -
Formas del deseo en los movimientos feministas recientes en América Latina
López, Natalia; Wurst, Vera (2023)El presente artículo analiza los movimientos feministas recientes en América Latina a partir del modo en que operan los afectos, especialmente las modalidades y producciones del deseo en la configuración de sus prácticas ... -
Formation and desorption of organic molecules: Resolving their emission in a prominent protostellar hot core and its outflow
Busch, Laura Ann (2024-03-15)Star-forming regions are known to be sites of a rich chemistry involving a variety of molecules. Interstellar complex organic molecules (COMs) are thereby of particular interest. They might act as precursors to larger and ... -
Formation and reactions of P-amino substituted Li/Cl phosphinidenoid complexes
Junker, Philip (2021-03-25)In this PhD Thesis results on the synthesis of P-amino substituted Li/Cl phosphinidenoid complexes are presented, with a particular focus on their reactivity in polar and apolar solvents and characteristic trapping reactions ... -
The formation and the stellar populations of dwarf galaxies
Dabringhausen, Jörg (2013-11-14)Ultra-compact dwarf galaxies (UCDs) are stellar systems with masses similar to those of dwarf elliptical galaxies (dEs), but with characteristic radii that are about a factor of ten smaller than those of dEs. One of the ... -
Formation mechanisms and aroma potential of 2-aminoacetophenone in boar fat
Gerlach, Christoph (2019-03-21)For decades the surgical castration of male piglets has been a common practice to avoid the incidence of boar taint within Europe. Boar taint is known as an offensive off-flavour occurring when meat of uncastrated boars ... -
The formation mechanisms of classical emission line stars
Hastings, Ben James (2023-10-10)Classical emission line stars are known fast rotators hosting a decretion disc in which emission lines are formed. Since their discovery in 1866, the formation mechanism of this class of stars has proved difficult to ... -
Formation Navigation and Relative Localisation of Multi-Robot Systems
Schneider, Frank E. (2013-05-07)When proceeding from single to multiple robots, cooperative action is one of the most relevant topics. The domain of robotic security systems contains typical applications for a multi-robot system (MRS). Possible scenarios ... -
Formation of low-mass helium white dwarfs orbiting binary millisecond pulsars
Istrate, Alina G. (2017-04-25)Millisecond pulsars (MSPs) belong to a class of radio pulsars characterized by high rotational spin rates and low magnetic fields. These neutron stars are believed to be the end-product of binary evolution, in which an old ... -
The Formation of the Concertina Pattern: Experiments, Analysis, and Numerical Simulations
Steiner, Jutta (2011-09-12)The concertina is a magnetization pattern observed in elongated thin-film elements of a soft-magnetic material during the switching-process by an external magnetic field. The almost periodic pattern consists of stripe-like ... -
