Fluorescence-based systems for detection of abiotic stresses on horticultural crops
Kautz, Burkard (2016-05-10)The main objective of this thesis was to assess the impact of economically important abiotic stresses on the plant physiology using non-destructive fluorescence indices, and to evaluate the potential use of the sensor ... -
Folate, vitamin B6, and vitamin B12 status in European adolescents: associations with homocysteine as well as communicable and non-communicable factors
Al-Tahan, Jasmin (2010-07-06)Adolescence implies important psychological, social, and physiological changes. Apart from the first year of life, both energy and nutrient requirements are greatest during adolescence. To ensure physiological growth during ... -
Food price volatility: the role of stocks and trade
Kornher, Lukas (2015-10-14)After a period of relatively low international food price volatility since the 1970s, prices spiked in 2007/2008 and 2011. These international price changes transmitted to domestic markets where they generate extra volatility. ... -
Food Security Monitoring for Developing Countries in the Age of Big Data
Weber, Regine (2020-02-10)Approximately 817 million people are currently estimated to be undernourished and 85 million people across 46 countries are estimated to be in need of food emergency assistance over the course of 2019. Conflict, migration ... -
Food waste reduction concepts for stakeholders in the food supply chain and auxiliary organizations
Strotmann, Christina (2019-09-10)The objective of this thesis was to develop concepts to support the reduction of food waste in the food sector. The concepts are targeted to private companies, such as manufacturing businesses, retailers, and large-scale ... -
Foreign Direct Investment in the Agribusiness Sector
Adenäuer, Lucie (2011-06-10)Foreign Direct Investment (FDI) has increased strongly since 2003, especially into the agribusiness sector. This development has rarely been analysed in recent literature. Therefore, this thesis aims at analysing different ... -
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 ... -
From lab to field - investigations of phosphorus availability from sugarcane bagasse ash to soybeans
Dombinov, Vitalij (2021-05-26)Every year the Brazilian sugarcane industry generates up to 10 million tons (dry matter) of ash from the combustion of sugarcane bagasse, which is a fibrous plant material that remains after sugarcane juice extraction. ... -
