Molecular characterization of porcine genes encoding complement components of the terminal lytic pathway and their association with hemolytic complement activity
(2009-06-02)
Activation of the complement system from three different pathways (classical, alternative and lectin pathway) results in the generation of the C3-convertase enzyme, which plays a key role in formation of the membrane attack ...
Chrom(VI)-Analyse, Chrom(VI)-Belastungen nordrhein-westfälischer Böden und Modellversuche zur Chrom(VI)-Reduktion und Chrom(III)-Oxidation in Böden
(2009-01-28)
Chrom kann aufgrund vielfältiger industrieller Nutzung als Cr(III) und Cr(VI) in Umweltkompartimente wie Böden gelangen. Insbesondere Cr(VI) kann aufgrund seiner hohen Mobilität und Toxizität ein wesentliches Umweltrisiko ...
Functional analysis of bovine DNMT1 during bovine embryo development and its association with Bull fertility traits
(2009-10-23)
This study was conducted to investigate the effects of suppressing and inhibiting DNMT1 on the embryonic development and bull fertility traits. In the first approach, in vitro produced zygotes were assigned ...
Water Relations and Drought Tolerance of Different Zea mays Cultivars as Influenced by Nitrogen Form and Application
(2009-11-12)
This study was conducted to describe the physiological and morphological factors controlling the water use efficiency of maize (Zea mays L.) plants under drought conditions. The effects of localized ammonium (CULTAN) and ......

Visual SLAM from image sequences acquired by unmanned aerial vehicles
(2009-12-08)
This thesis shows that Kalman filter based approaches are sufficient for the task of simultaneous localization and mapping from image sequences acquired by unmanned aerial vehicles. Using solely direction measurements to ...
Options for reuse of nutrients from waste water in the Mekong Delta, Vietnam
(2010-12-19)
Different options for wastewater treatment in the Mekong Delta were studied to recycle nutrients efficiently for later use in agriculture.
Due to an even distribution of nutrients between animal and human excrements ...

Bovine pre-transfer endometrium and embryo transcriptome fingerprints as predictors of pregnancy success after embryo transfer
(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 ...
MicroRNAs in the bovine ovary and placentas derived from in vivo, in vitro and nuclear transfer pregnancies
(2010-12-15)
MicroRNAs are the major class of gene regulating molecules playing pivotal roles at post-transcriptional level. Identification and expression profiling are the initial steps to understand their regulation of biological ...
Endophytic Fusarium oxysporum: Phylogeny and induced defense responses in banana plants against Radopholus similis
(2010-09-07)
The burrowing nematode Radopholus similis is a destructive pest of banana causing severe yield losses in plantations worldwide. R. similis infestation of the banana root is significantly reduced, when the root system is ......
