A 24-hour food list for dietary assessment in large-scale epidemiological studies
(2015-06-18)The validity of dietary assessment in large-scale cohort studies has been questioned. Combining different instruments for the assessment of consumption probability and amounts consumed might be feasible and improve the ... -
3D-Stadtmodellierung auf heterogenen Ausgangsmodellen mittels evolutionärer Algorithmen
(2007)Die vorliegende Arbeit beschreibt ein neuartiges Verfahrens zur flexiblen und effizienten 3D-Stadtmodellierung im Kontext der Verfügbarmachung von 3D-Stadtmodellen. Ausgangspunkt ist die Heterogenität existierender und ... -
AB-QTL analysis for two populations of winter barley sharing the donor of Hordeum vulgare ssp. spontaneum
(2005)The objective of the present study was to detect favourable exotic QTL alleles for the improvement of agronomic traits, pathogen resistance and non-parasitic browning in two BC2DH populations derived from the ... -
Abnormal profits and profit persistence: evidence from the European food industry
(2014-04-14)This thesis comprises three papers that aim to analyze the phenomenon of firm profits in the European food industry that differ from the competitive norm either at a specific point in time or over longer time periods. The ... -
Above- and belowground carbon stocks in semi-arid land-use systems under integrated watershed management in Gergera watershed, Ethiopia
(2016-12-06)Enhanced carbon stocks help to improve the productivity and resilience of farming systems, especially in smallholder communities relying on subsistent agriculture. This study investigated the total terrestrial stock of ... -

(2020-01-27)Attenuating the postprandial stress response and its associated inflammatory and endothelial events through specific nutritional and lifestyle interventions seems to be a promising and important approach to decrease the ... -
Adaptation assessment of a spring barley population to organic and conventional agro-ecosystems using genome sequencing approaches
(2021-07-26)Over the past few decades, plant breeding has contributed significantly to increased crop yields in industrial agriculture. Besides, alternative, environmentally friendly farming approaches became more popular in the past ... -
Adaptation strategies to climate change in inland valleys in Dano, Burkina Faso
(2021-06-16)The agriculture in Sub Saharan Africa at many locations is under-performing and lags behind the other continents in terms of yields as well as productivity. The recent progression in the produced quantities is mainly due ... -
Adhäsion und Entwicklung von Venturia inaequalis (Cke.) Wint. auf Apfel- und Modelloberflächen
(2007)Für einen erfolgreichen Infektionsverlauf muss ein Pathogen in der Lage sein, sich auf der Wirtspflanze zu etablieren, um anschließend in das Gewebe einzudringen. In der frühen Phase der Pathogenese steht das Pathogen in ... -
Adiponectin in Cattle: Profiling of molecular weight patterns in different body fluids at different physiological states and assessment of adiponectin’s effects on lymphocytes
(2014-07-07)Adiponectin (AdipoQ), one of the most abundant adipokines found in circulation exerts various meta-bolic functions, e.g. improving insulin sensitivity and ameliorating tissue inflammation. It is secreted in different ... -
Advances in technology evaluation and decision support studies using bio-economic farm models
(2022-04-11)The use of so-called bio-economic farm models makes it possible to determine the most cost-effective adaptation strategy to novel policy measures and to evaluate whether the use of new technologies can be economically ... -
The aerobic deterioration of silages as estimated from chemical composition and dietary choice by goats
(2013-06-06)Conserved forage as silage provides an important source of energy and nutrients for livestock in many countries of the world. After opening the silo for the feed-out phase or due to damages of the covering, oxygen ingresses ... -
African nightshade and African spinach: A neglected and underutilized resource with significant potential to manage plant-parasitic nematodes
(2019-05-07)African indigenous vegetables (AIV) are essential for dietary diversification and ensuring nutritional requirements for people in sub-Sahara Africa. AIV have been largely marginalized by agriculture research, yet they are ... -
