This report addresses some of our observations made in a dozen of projects in the area of software testing, and more specifically, in automated testing. It documents, analyzes and consolidates what we consider to be of interest to the community. The major findings can be summarized in a number of lessons learned, covering test strategy, testability, daily(More)
The widespread use of brominated flame-retarded products in the last two decades has resulted in an increasing presence of bromine in thermal processes such as waste combustion and accidental fires. Brominated and brominated-chlorinated dibenzodioxins and dibenzofurans (PBDDs/PBDFs, PXDDs/PXDFs) are micropollutants of concern arising from such processes.(More)
Heterozygous mutations in the cardiac homeobox gene, NKX2-5, underlie familial cases of atrial septal defect (ASD) with severe atrioventricular conduction block. In this study, mice heterozygous for Nkx2-5-null alleles were assessed for analogous defects. Although ASD occurred only rarely, atrial septal dysmorphogenesis was evident as increased frequencies(More)
As scientists and other professionals from a variety of disciplines, we are concerned about the production and release into the environment of an increasing number of poly-and perfluoroalkyl substances (PFASs) for the following reasons: 1. PFASs are man-made and found everywhere. PFASs are highly persistent, as they contain perfluorinated chains that only(More)
Since the 1970s, an increasing number of regulations have expanded the use of brominated and chlorinated flame retardants. Many of these chemicals are now recognized as global contaminants and are associated with adverse health effects in animals and humans, including endocrine and thyroid disruption, immunotoxicity, reproductive toxicity, cancer, and(More)
Recently, tools for the analysis and visualization of code coverage have become widely available. At first glance, their value in assessing and improving the quality of automated test suites seems to be obvious. Yet, experimental studies as well as experience from projects in industry indicate that their use is not without pitfalls. We found these tools in(More)
Thoracic aortic aneurysms can be triggered by genetic disorders such as Marfan syndrome (MFS) and related aortic diseases as well as by inflammatory disorders such as giant cell arteritis or atherosclerosis. In all these conditions, cardiovascular risk factors, such as systemic arterial hypertension, may contribute to faster rate of aneurysm progression.(More)
This report describes experiences the authors made over a period of approximately 15 months in a software development and maintenance project in the banking area. It analyzes how the project team managed the transition from the development to the maintenance phase under rather difficult circumstances. The report starts with a description of the project(More)
Unterentwickelte abgestorbene Früchte (Fruchtmumien) können an bestimmten Sorten von Tafeläpfeln wie ‘Elstar’ oder Zieräpfeln wie ‘Golden Hornet’ über 12 Monate lang am Baum verbleiben und werden dadurch zum geeigneten Substrat für Pilze. Eine Methode zum Nachweis der Besiedlung solcher Fruchtmumien durch wichtige pilzliche Erreger von Fruchtfäulen wurde(More)
Chlorinated pesticides can contain impurities of dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and their precursors, as a result of various manufacturing processes and conditions. As precursor formation of PCDD/Fs can also be mediated by ultraviolet light (UV), this study investigated whether PCDD/Fs are formed when currently used pesticides are exposed to(More)
