Nutritional status and related factors in nursing home residents: Comparative study in elderly migrants and native Germans
(2011-04-15)
Introduction: Elderly migrants represent an ever increasing portion of German nursing home residents. However, the nutritional status of elderly migrants and related problems are still largely unknown. The ...
Association and expression study of CD9, PLCz and COX-2 as candidate genes to improve boar sperm quality and fertility traits
(2011-04-06)
The transcription factors tetraspanin CD9 (CD9), phospholipase C zeta (PLCz) and cyclooxygenase isoenzyme type 2 (COX-2) are believed to play a key role in spermatogenesis in rat, mouse and human. However, no study was ...
Identification of positional and functional candidate genes for meat and carcass quality in F2 Duroc x Pietrain resource population
(2011-04-06)
Five genes, AMBP, GC, PPP1R3B, TNC and IFI6, whose candidacy for meat and carcass quality traits arises from their trait-dependent differential expression and/or trait correlated expression, were selected for analysis. ...
Evaluation of dual purpose cowpea varieties for dry season feeding of ruminant animals
(2011-03-29)
Cowpea is of major importance to the livelihoods of millions of people in the tropics. Resource-poor small-holder farmers derive food, animal feed, cash and manure from the crop. Dual purpose cowpea has the potential to ......

Die Kuhbohne (Vigna unguiculata L. Walp) stellt eine ......
Bewertung von unterschiedlichen Zweinutzungssortentypen der Kuhbohne (Vigna unguiculata) für die Ernährung von Wiederkäuern in der Trockenzeit
Die Kuhbohne (Vigna unguiculata L. Walp) stellt eine ......
Collaborative Working Environments: Group Needs Approach to Designing Systems for Supporting Spatially Distributed Groups
(2011-02-24)
Collaboration in spatially distributed groups requires technological support for mediating collaborative activities and members’ interactions over time and distance. Technology provides multiple tools for supporting ...
Institutional Vulnerability and Governance of Disaster Risk Reduction: Macro, Meso and Micro Scale Assessment: With Case Studies from Indonesia
(2011-07-14)
This PhD research addresses two central questions: How should institutional vulnerability that shapes disaster risks and disaster reduction policy be assessed? How does the quality of institutions and governance influence ...
Soil organic carbon pools and their spatial patterns: rapid assessment using mid-infrared spectroscopy
(2011-02-09)
Soil organic carbon (SOC) plays an important role in global C cycling. Until today, the spatial patterns of individual SOC fractions are, however, largely undiscovered as traditional methods for their determination are too ...
Detection, identification, and quantification of fungal diseases of sugar beet leaves using imaging and non-imaging hyperspectral techniques
(2011-02-22)
Plant diseases influence the optical properties of plants in different ways. Depending on the host pathogen system and disease specific symptoms, different regions of the reflectance spectrum are affected, resulting in ...
Improving the water productivity of integrated crop-livestock systems in the semi-arid tropics of Zimbabwe: an ex-ante analysis using simulation modeling
(2011-07-11)
The semi-arid tropics of Zimbabwe are characterised by low levels of economic activity, high incidence of land degradation and a high concentration of the rural poor. Water scarcity is also a principle constraint, and ...
Identification of expression quantitative trait loci (eQTL) and candidate genes associated with water holding capacity in porcine meat
(2011-01-19)
Consumer assessment of meat quality is defined by the characteristics of sensory experience such as juiciness, muscle pH, water-holding capacity and colour. Water-holding capacity in terms of drip loss has a genetic as ...
