Boundary work and agricultural innovation systems: Stakeholder interaction and learning using an example of push-pull technology in Ethiopia
Nyang'au, Isaac Mbeche (2019-06-17)Maize is an important cereal crop for food security in Ethiopia. However, its productivity is low with average grain yields of less than 1 ton/ha which is below its potential of over 4 ton/ha. This is attributed to a variety ... -
Bovine microRNomics: Implications during oocyte maturation and pathophysiology of endometrium
Hailemariam, Dagnachew Worku (2011-05-04)MicroRNAs which are known for posttranscriptional gene regulation are evidenced for their essential role during animal development and disease. In this study, identification and expression profiling of bovine miRNAs during ... -
Bovine ovarian hyperstimulation induced changes in expression profile of circulatory miRNA in follicular fluid and blood plasma
Seifi Noferesti, Sina (2014-11-14)Circulatory noncoding small RNAs (miRNAs), which are present in various body fluids, are reported to be potentially used as biomarkers for disease and pregnancy. The present study was conducted to investigate the effect ... -
Bovine pre-transfer endometrium and embryo transcriptome fingerprints as predictors of pregnancy success after embryo transfer
Salilew Wondim, Dessie (2010-10-08)Aberrant endometrial and embryonic gene expression is one of the causes of pregnancy failure in cattle. However, selecting cows with adequate endometrial receptivity and embryos of higher developmental competence based on ... -
Die Böden des oberen Ouémé-Einzugsgebietes in Benin/Westafrika: Pedologie, Klassifizierung, Nutzung und Degradierung
Junge, Birte (2004)In dieser Arbeit werden die im oberen Ouémé-Einzugsgebiet Zentralbenins gelegenen Böden charakterisiert und die Degradierung in dem aktuellen low input-Landnutzungssystem untersucht. Darauf aufbauend werden Möglichkeiten ... -
Brachflächenrevitalisierung im Rahmen der Flächenkreislaufwirtschaft
Weitkamp, Alexandra (2009)In Deutschland wird eine nachhaltige Siedlungspolitik verfolgt, die einen sparsamen Umgang mit Grund und Boden in sozialverträglicher und ökologischer Flächennutzung vorsieht. Daher hat die Bundesregierung sich zur ... -
Breeding progress for drought tolerance and nitrogen use efficiency in winter wheat (Triticum aestivum L.)
Koua, Ahossi Patrice (2022-03-28)Drought is the major abiotic stress factor limiting agricultural production in arid, semi-arid as well as in temperate regions around the world, whereas nitrogen (N) is one of the most important nutrients for crop production. ... -
Broken Roads and Broken Laws: How Infrastructure and Law Enforcement Shape Amazonian Deforestation Frontiers
Schielein, Johannes (2020-06-29)Deforestation of tropical rainforests contributes significantly to global climate change and accelerated biodiversity loss. To mitigate these impacts, the goal of drastically reducing tropical deforestation has been a ... -
Calibration of Terrestrial Laser Scanners: Kalibrierung terrestrischer Laserscanner
Holst, Christoph; Neuner, Hans; Wieser, Andreas; Wunderlich, Thomas; Kuhlmann, Heiner (2016)The calibration of a laser scanner is necessary to reduce systematic errors in the acquired point cloud. Furthermore, calibrating laser scanners is motivated by the need of users to access up-to-date quality information. ... -
Can we model the effect of observed sea level rise on tides?
Schindelegger, Michael; Green, Mattias; Wilmes, Sophie-Berenice; Haigh, Ivan (2018-06-07)The link between secular changes in the lunar semidiurnal ocean tide (M2) and relative sea level rise is examined based on numerical tidal modeling and the analysis of long-term sea level records from Europe, Australia, ... -
