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 ... -
Volatility of International Food Prices: Impacts on Resource Allocation and on Food Supply Response
(2015-06-08)Uncertainty is a quintessential feature of agricultural commodity prices. After about three decades of low and relatively stable price levels, we have experienced a dramatic rise and volatility in international food prices ... -
Crop management options to reduce nitrogen pollution in Liangzihu lake basin, Central China
(2015-06-18)In Central China, high mineral nitrogen (N) application rates lead to low N recovery and high N losses. Large amounts of the nitrate-N leached from agricultural soil end up in aquatic ecosystems, which negatively affects ... -
International analyses of natural resource curse and Kazakhstan’s related economic performance with special attention to its wheat and energy sectors
(2015-09-09)The bottom line of this study is to examine the role of natural resource endowments for economic growth and institutional quality with special focus on Kazakhstan and CIS countries. It is documented that resource rents ... -
The Determinants of Long-Term Growth in Smallholder Agriculture in Rwanda: An Intergenerational Analysis
(2015-06-03)The current study explores the determinants of long-term growth in small-scale agriculture in a rural area of Rwanda, with a special focus on intergenerational mobility of income and poverty over the past two and a half ... -
The private sector and the marginalized poor: An assessment of the potential role of business in reducing poverty and marginality in rural Ethiopia
(2015-04-16)The present research analyzes the role that the private sector can play in reducing poverty and marginality in Ethiopia by providing improved agricultural inputs to marginalized poor farmers. Two important insights motivate ... -
Silage maize variety and heat stress: effects on nutritive value of maize silage and on digestion events and performance of ruminants
(2015-05-05)The present thesis addresses two topics; brown-midrib (Bm) silage maize and heat stress in ruminants. The first part of this thesis focused on an experimental Bm silage maize hybrid with regard to dry matter (DM) intake ... -
MiRNAs as regulators of gene expression modulate development and energy metabolism of skeletal muscle
(2015-06-18)It is important to understand the molecular networks affecting biological properties of muscle in order to improve the efficiency of meat production and meat quality in domestic animals. The discovery of miRNA represents ... -
Price effects from the financialization of agricultural commodity markets
(2015-05-12)Supposed portfolio benefits of commodities and the increased availability of commodity linked investment products such as index funds contribute to a financialization of agricultural commodity markets. The parallel increase ... -
Innate immune responses of LPS treated porcine monocyte-derived dendritic cells after exposure to the histone deacetylase inhibitor sulforaphane
(2015-03-30)Epigenetic mechanisms are believed to regulate the expression of immune gene and the development of inflammation. Dendritic cells (DCs) are crucial to sense microbial pathogens by their phagocytosis and by altering the ... -
NRF2 mediated oxidative stress response activity during early in vitro bovine embryo development
(2015-03-30)Overcoming oxidative stress is one of the various embryo challenges to survive under suboptimal conditions during in vitro production of bovine embryos. Thus, the present study aimed to examine the ability of preimplantation ... -
