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 ... -
Empowerment of Girls and Women in Rural Pakistan: Migration, Decision-making and Consciousness
Saleemi, Sundus (2020-11-24)This thesis analyses the effect of migration of men on women and children left behind in rural households in Pakistan. Part one analyses the impact on left-behind women’s participation in household decisions and number of ... -
Iron isotope fractionation in arable soil and graminaceous crops
Xing, Ying (2020-11-24)Soils contain large quantities of Fe, however, the Fe-solubility is very low. Plants have developed two efficient strategies to secure Fe uptake from soil under Fe-deficient conditions: (i) the sequential acidification-r ... -
The role of post-harvest supplementary light exposure for ripening and quality development of tomato fruit
Panjai, Lachinee (2020-11-23)The major aim of the present work was to evaluate the optimal exposure time and effects of red light and short periods of daily ultraviolet (UV) on the post-harvest quality of green tomato fruit during ripening. The ... -
A water storage reanalysis over the European continent: assimilation of GRACE data into a high-resolution hydrological model and validation
Springer, Anne (2019-04-18)Continental water storage and redistribution within the Earth’s system are key variables of the terrestrial water cycle. Changes in water storage and fluxes may affect resources for drinking water and irrigation, lead to ... -
Zum Einfluss der räumlichen Auflösung und verschiedener Qualitätsstufen auf die Modellierungsgenauigkeit einer Ebene beim terrestrischen Laserscanning: The Impact of Spatial Resolution and Different Quality Levels on the Modeling Accuracy of a Plane Using Terrestrial Laser Scanning
Heinz, Erik; Holst, Christoph; Kuhlmann, Heiner (2019)Terrestrische Laserscanner sind in der Lage, unsere Umgebung in Form von Punktwolken dreidimensional zu erfassen. Hierbei kann geräteintern in der Regel zwischen verschiedenen räumlichen Auflösungsstufen und auch ... -
Survey Configuration for Terrestrial Laser Scanning: Aufnahmekonfiguration für Terrestrisches Laserscanning
Wujanz, Daniel; Holst, Christoph; Neitzel, Frank; Kuhlmann, Heiner; Niemeier, Wolfgang; Schwieger, Volker (2016)Despite the enormous popularity of terrestrial laser scanners in the field of geodesy and related sciences the vital task of viewpoint planning is mostly considered intuitively. In contrast to established acquisition ... -
Overview on Current Modelling Strategies of Point Clouds for Deformation Analysis: Überblick aktueller Methoden zur Modellierung von Punktwolken für die Deformationsanalyse
