Exact Optimization Algorithms for the Aggregation of Spatial Data
Oehrlein, Johannes (2020-12-16)The aggregation of spatial data is a recurring problem in geoinformation science. Aggregating data means subsuming multiple pieces of information into a less complex representation. It is pursued for various reasons, like ... -
Exhaust air treatment systems for the mitigation of dust, ammonia and odour from poultry housing
Strohmaier, Johanna Carolina Luise (2020-11-26)Exhaust air treatment is becoming increasingly important in poultry husbandry with a rising number of animals kept per barn. An adaptation of the systems that already have been successfully used in pig husbandry only works ... -
Exosomal and non-exosomal circulatory miRNAs in bovine follicular fluid: potential role of exosomal miRNAs in oocyte development
Sohel, Mahmodul Hasan (2014-04-23)Growth and development of bovine follicle and oocyte is the result of series of complex and coordinated processes that involves extensive cell-to-cell communication in the follicle. This phenomenon involves enormous complex ... -
Experimental analysis and modelling of the rainfed rice cropping systems in West Africa
Worou, Omonlola Nadine (2012-07-18)There is a need to improve rice productivity to meet the increasing demand for rice in West Africa since it is acknowledged that existing rainfed rice cultivation practices deal with irregularities of climate like drought ... -
Experimentelle und numerische Untersuchungen zur Bestimmung gravimetrischer Gezeitenparameter im GeoObservatorium Odendorf
Eschmann, Marc (2007)Ziel der Untersuchung ist die Bestimmung der gravimetrischen Gezeitenparameter im GeoObservatorium Odendorf mit einer Maßstabsgenauigkeit von etwa 1‰ und einer Phasensicherheit der Hauptpartialtiden von etwa 0°,01. Dies ... -
Experimentelle Untersuchungen zum Einfluss von Nahrungsbestandteilen auf lithogene und inhibitorische Harnparameter beim Calciumoxalatsteinleiden am Beispiel von Fischöl und Hippursäure
Jansen, Brigitte (2008)Ziel einer erfolgreichen Rezidivprophylaxe des Calciumoxalat-Harnsteinleidens ist es - neben der Harndilution - die renale Exkretion lithogener Substanzen zu verringern und die der Kristallisationshemmer, sogenannter ... -
Experimentelle Untersuchungen zur Feuchtgetreidekonservierung im Folienschlauch
Matthiesen, Momme (2008)Das Verfahren der Einlagerung von gequetschtem Futtergetreide in Folienschläuchen mit einer Schlauchpresse mit integrierter Walzenquetsche (Crimper-Bagger) stellt eine technische Alternative zu konventionellen Techniken ... -
Experimentelle Untersuchungen zur vergleichenden Qualitätsbeurteilung von Silagen mit einem Chemosensor-System
Roß, Fabian Heribert (2014-11-20)In dem Verbundprojekt "Qualität von Gärfutter – komparative Bewertung mittels chemischer Analyse, Chemosensor-Systemen und Tierversuchen" wurden verschiedene Silagequalitätsvarianten systematisch hinsichtlich Schmackhaftigkeit, ... -
Experiments and numerical studies on transport of sulfadiazine in soil columns
Unold, Myriam (2010-12-01)Veterinary antibiotics like sulfadiazine (SDZ) are used in large amounts worldwide. Excreted as parent compounds or in the form of metabolites they reach agricultural soils mainly via spreading of manure or sewage sludge ... -
An Exploration of the Potential of Producing Biofuels and the Prospective Influence of Biofuels Production on Poverty Alleviation among Small-Scale Farmers in Tanzania
Philip, Damas (2007)Tanzania is among the countries which depend entirely on imports for their oil needs. Consequently, the recent increases in world oil prices have led to rapid increases in the country’s expenditure on petrol and diesel ... -
