Ellinger, Sabine (2004)<strong>Problemstellung</strong>: Polyphenole sind sekundäre Pflanzenstoffe, die in allen pflanzlichen Nahrungsmitteln vorkommen, in besonders hoher Konzentration im Rotwein. Ihnen werden zahlreiche biologische Wirkungen ... -
Intestinal integrity characteristics of growing pigs in response to oregano essential oil supplementation
Hofmann, Haiko Hendrik (2021-09-06)The production of protein of animal origin is of great importance worldwide. In Germany, pig production is of considerable importance to meet this need. To ensure successful animal production, an intact intestinal tract ... -
The intrinsic microbial degradation potential of shallow aquifers with respect to crop protection agents
Voß, Thorsten (2010-08-18)Active substances in crop protection agents are assessed by a community procedure, and a comprehensive dossier including data and tests is part of the application. The studies must be performed according to specified ... -
Intrinsically antimicrobial active polymers to improve the hygienic conditions during processing and preparation of fresh meat
Hüwe, Carina (2018-12-10)The objective of this thesis was the investigation of the potential of intrinsically antimicrobial active polymers to improve the hygienic conditions in all steps of the processing and preparation of fresh meat, from the ... -
Introgression von Resistenzgenen gegen Drechslera teres (Netzflecken an Gerste) aus Wildgerste H. vulgare ssp. spontaneum in Kulturgerste H. vulgare ssp. vulgare
Gay, Alexandra G. (2005)Dem Erreger der Netzfleckenkrankheit an Gerste, <i>Pyrenophora teres</i>, kommt bei den pilzlich bedingten Blattkrankheiten der Gerste eine immer wichtiger werdende wirtschaftliche Bedeutung zu. Grund hierfür ist vor allem ... -
Investigating the Potential of UAV-Based Low-Cost Camera Imagery for Measuring Biophysical Variables in Maize
Tewes, Andreas (2018-11-27)The potential for improved crop productivity is readily investigated in agronomic field experiments. Frequent measurements of biophysical crop variables are necessary to allow for confident statements on crop performance. ... -
Investigation of miRNAs enrichment and degradation in bovine granulosa cells during follicular development
Ahmad, Ijaz (2014-12-01)The granulosa cells in the mammalian ovarian follicle respond to gonadotropin signalling and are involved in the processes of folliculogenesis and oocyte maturation. Although, several studies have been done on spatio ... -
Investigation of the feeding process at concentrate feeding stations for horses in group housing
Gülden, Aline (2018-04-26)Computer-controlled concentrate feeding stations are increasingly used to guarantee an individual feed supply of group-housed horses. Blocking times caused by horses remaining in the feeding station without concentrate ... -
Investigation on host-parasite interaction between the stem nematode Ditylenchus dipsaci and sugar beet Beta vulgaris and their importance for development of alternative integrated management strategies
Kühnhold, Volker (2011-11-16)The re-occurrence and rapid spread of D. dipaci in German sugar beet production areas enhanced the necessity for a holistic management strategy of this pathogen to secure sustainable sugar production. <br /> To evaluate ... -
