Adjuvant-induced alterations of cuticular waxes and their consequences for mechanisms of drought stress resistance
(2023-07-26)The most important function of the cuticular waxes is the shielding of the plant from uncontrolled water loss as well as from pathogens, UV radiation and pollutants. Penetrating agrochemicals are also effectively shielded ... -
Bayesian Adaptive Markov Chain Monte Carlo Estimation of Genetic Parameters
(2012-04-18)Accurate estimation of genetic parameters is crucial for an efficient genetic evaluation system. REML and Bayesian methods are commonly used for the estimation of genetic parameters. In Bayesian approach, the idea is to ... -
Challenges and opportunities of using ecological and remote sensing variables for crop pest and disease mapping
(2019-07-15)Crop pest and diseases are responsible for major economic losses in the agricultural systems in Africa resulting in food insecurity. Potential yield losses for major crops across Africa are mainly caused by pests and ... -
Conceptualising and estimating rationalised agricultural optimisation models
(2018-07-19)Computational modelling for quantitative agricultural policy assessment in the EU employs more farm level oriented approaches in recent years. This follows policy instruments that increasingly target the farm level and ... -
Digital Filtering Algorithms for Decorrelation within Large Least Squares Problems
(2008)The GOCE (Gravity Field and steady-state Ocean Circulation Explorer) mission is dedicated to the determination of the Earth's gravity field. During the mission period of at least one year the GOCE satellite will collect ... -
Market expectations, public information and uncertainty resolution in agricultural commodity and equity markets
(2023-12-14)The Efficient Market Hypothesis (EMH) states that price movements result from changes in market expectations when new information becomes available. This thesis focuses on such revisions of expectations around the releases ... -
Methods of analysis and empirical evidence of farm structural change
(2014-08-27)The dissertation aims to develop and apply new empirical methods to analyze and model farm structural change. Changes of the farm structure are not only important for the sector itself but may have broader economic, social ... -
Optimization of point grids in regional satellite gravity analysis using a Bayesian approach
(2020-03-25)The subject of this thesis is the global and regional gravity field determination from GOCE data using the short arc approach. The focus is on the extension of the regional method regarding an adaption of the model resolution ... -
Resilience, collapse and reorganization of a rangeland socio-ecological system in South Africa
(2016-05-24)Communal rangelands in semi-arid areas are complex socio-ecological systems (SES). Their complexity arises from non-linear feedbacks between the social- and the ecosystem. To understand the social system requires tackling ... -
Water Quality in Multipurpose Water Systems, Sanitation, Hygiene and Health Outcomes in Ghana
(2018-03-29)This thesis examines the interlinkages between water quality, water use, sanitation and hygiene practices, other household characteristics and health outcomes in the context of multipurpose water systems in Ghana. ...
