Diagnose und Bewertung phytopathogener Viren im rheinischen Gemüsebau
Hennes, Imke; Noga, Georg (2003)Seit 1996 wurden an verschiedenen rheinischen Gemüsebaukulturen Blatt- und Fruchtdeformationen beobachtet, die in erheblichen Ertragsverlusten, teilweise sogar Ernteausfällen resultierten. Nachdem andere Ursachen für die ... -
Diagnosing and managing zinc and boron deficiencies in emerging crop production systems of Nepal
Shrestha, Shova (2020-12-02)The productivity and sustainability of the prevailing crop production systems are being challenged throughout the Indo-Gangetic Plains. Limiting water resources, depletion of soil fertility, social changes and economic ... -
Dietary strategies to optimize energy and glucose supply to lactating dairy cows
Benninghoff, Jens (2015-11-24)Ruminants usually absorb only small quantities of glucose directly from the small intestine, because the majority of the glucose, regardless of dietary source, is fermented in the rumen to short chain fatty acids. Thus, ... -
Differences among domestic chicken breeds in tonic immobility responses as a measure of fearfulness
Tiemann, Inga; Becker, Senta; Fournier, Jocelyn; Damiran, Daalkhaijav; Büscher, Wolfgang; Hillemacher, Sonja (2023-04-04)Background: One priority for animal welfare is for animals to experience less fear, especially during human contact. For domestic animals, breeds that are less fearful may provide genetic resources to develop strains with ... -
Digital Filtering Algorithms for Decorrelation within Large Least Squares Problems
Siemes, Christian (2008)The GOCE (Gravity Field and steady-state Ocean Circulation Explorer) mission is dedicated to the determination of the Earth's gravity field. During the mission period of at least one year the GOCE satellite will collect ... -
Digital filtering algorithms for decorrelation within large least squares problems
Siemes, Christian (2012)The GOCE (Gravity Field and steady-state Ocean Circulation Explorer) mission is dedicated to the determination of the Earth's gravity field. During the mission period of at least one year the GOCE satellite will collect ... -
Digital soil mapping using survey data and soil organic carbon dynamics in semi-arid Burkina Faso
Hounkpatin, Kpadé Ozias Laurentin (2018-04-27)With computer-assisted geostatistics and data mining methods, digital soil mapping (DSM) offers new possibilities for providing soil spatial information for data scarce areas such as West Africa. Such information could ... -
Dimensioning Branched Water Distribution Networks for Agriculture
Costa Pedroso, Rui Miguel (2014-05-26)The implementation of water distribution networks for irrigation represents an important investment for the development of many countries and for food security. These investments are mostly executed based solely on engineering ... -
Direct Georeferencing for Portable Mapping Systems: In the Air and on the Ground
Klingbeil, Lasse; Eling, Christian; Heinz, Erik; Wieland, Markus (2017-11)During the last few years, the acquisition of geometric information about objects by using a moving sensor platform has gained increasing popularity in the surveying community. A large number of companies offer vehicle-based ... -
Direct use of urine as fertilizer: potential risks of loading pharmaceuticals and hormones to field crops
Arias Escobar, Maria Alejandra (2019-04-11)Ecological sanitation or Ecosan is an alternative approach to avoid the disadvantages of conventional water-based sanitation systems. This approach, based on ecosystem functioning and the closure of material flow cycles, ... -
Dissecting Class A Scavenger Receptor Mediated Cell Adhesion and Lipoprotein Internalization
Kosswig, Ninetta (2003)Macrophage Class A scavenger receptors (SR-A) are trimeric transmembrane glycoproteins that can bind a variety of ligands including modified lipoproteins and bacterial products. Through its ability to internalize these ... -
Dissecting rhizobacteria-induced systemic resistance in tomato against Meloidogyne incognita: The first step using molecular tools
Silvestre Garcia, Kerstin (2007)Two rhizobacteria with known ability to induce systemic resistance against different soilborne pathogens were studied in split-root experiments for their ability to induce systemic resistance against the root-knot nematode ... -
Disseminating sustainable intensification practices: Empirical evidence from Ghana
Mellon Bedi, Shaibu (2022-06-02)Adoption of sustainable intensification (SI) of agricultural practices is essential for increasing food production in more sustainable way. Dis-adoption of agricultural technologies is pervasive among smallholder farmers ... -
