    Dynamic programming languages are highly popular and widely used. Java-Script is often called the lingua franca of the web and it is the de facto standardfor client-side web programming. On the server-side the PHP, Python andRuby languages are prevalent. What these languages have in common isan expressive power which is not easily captured by any static type system.These, and similar dynamic languages, are often praised for their ease-of-useand flexibility. Unfortunately, this dynamism comes at a great cost: The lack ofa type system implies that most errors are not discovered until run-time. Thus,in the worst-case, these bugs are not uncovered before they are encounteredby real users of the system. A further cost is limited tool support: For instance,integrated development environments with code completion, code navigationand automatic refactorings are widely available for languages with static typesystems, such as Java and C# , but the same features are rarely available fordynamic languages such as JavaScript.The aim of this thesis is to investigate techniques for improving the tool-support for dynamic programming languages without imposing any artificialrestrictions on the behaviour of these languages. A common theme is thereliance on static program analysis to over-approximate the behaviour ofprograms written in these languages. Specifically, the use of whole-programdataflow analysis. The research challenge of this line of work is the adaptionof existing- and invention of new dataflow analysis techniques to tackle thenature of dynamic programming languages.

    These recommendations for guidelines provide safety requirements and guidance to ensure the safe management of waste containing naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive material (TENORM) generated from Greenland's mineral and hydrocarbons industries. The recommendations for guidelines include requirements for all phases of the waste facility, e.g., site selection, site assessment, site design and preparation, construction, operation (e.g., treatment, disposal), closure, site release from licensing, and long-term stewardship. Herein recommendations for guidelines are based on the most recent international standards recommended by the International Commission on Radiological Protection, European Union, International Atomic Energy Agency, and International Council on Mining and Metals. The recommended herein waste management practice is a graduated approach. This means that the greater the risk, the more stringent the mitigation measures should be. The policy, practice, regulation, and supervision should (shall) be continuously improved to comply with the existing best available technologies (BAT), best environ-mental practices (BEP), and changing levels of understanding within the management of radioactive waste. The Environmental Agency for Mineral Resources Activities (EAMRA) requested in 2018 recommendations for ''Guidelines for the safe management of radio-active waste generated from the mineral activities in Greenland.'' In 2020, EAMRA re-quested that the DCE also include the safe management of radioactive waste generated from Greenland's hydrocarbons activities in the recommendations. As requested, the recommendations are provided in the format of draft guidelines. However, the Greenland administration's administrative setup is only tentatively indicated and should be further addressed by EAMRA.

    Myanmar is undergoing a comprehensive political transition. In April this year the first democratically elected government in six decades came into power under the leadership of NLD, the pro-democracy party headed by Aung San Suu Kyi. The largest peace conference in the country’s history was held in early September, and Myanmar again made the international headlines a week later when Kofi Annan visited the country to head a commission for addressing communal violence. These national events are crucial to the democratization process in Myanmar and for ending the almost seven decades of civil war. However, often overlooked in this larger picture of transition is the state of local democracy, including village level governance and everyday state-citizen engagements. Political changes at this level are equally crucial for the wider democratization process.This roundtable summary discusses the 2016 local elections of village tract and urban ward administrators and reflects on the future of local democracy and decentralization in Myanmar. Local administrators are the primary point of contact between the state and citizens. How they are elected and how they govern in the everyday are essential to understanding political developments at the most local level.

    Our current understanding of the complex digestive system of ruminants is mainly based on a few, but intensively studied livestock species. In comparison, information about the anatomy and function of the gastrointestinal tract of wild ruminants is limited. The aim of this thesis was to provide quantitative data on the digestive morphophysiology of the giraffe (Giraffa camelopardalis), the blackbuck (Antilope cervicapra) and the Arabian sand gazelle (Gazella subgutturosa marica). Digestive tract anatomy was characterized by dimensions and weights of the different gastrointestinal tract sections, and digesta samples were collected to describe the digestive function, as indirectly evidenced by the physical characteristics of the digesta. Of particular interest was to determine the presence/absence of rumen content stratification. The findings in each species were then evaluated against available data from other ruminant species, classified as either browsing ‘moose-type’ ruminants or grazing ‘cattle-type’ ruminants. The giraffe digestive morphophysiology generally resembled that of ‘moose-types’ ruminants, showing the same anatomical characteristics and having an unstratified rumen content. One exception was the relatively smaller parotid salivary glands found in giraffes compared to other ‘moose-type’ ruminants. Differences in rumen papillation pattern and fecal particle size between wild and captive giraffes indicate that adjustments should be made to the captive feeding programs. A feeding trial with various silage types revealed a potential for using silage as an alternative forage type. For logistical reasons it was not possible to further investigate this potential, as was originally an aim of the project. The blackbuck digestive morphophysiology generally resembled that of other grazing ruminants (‘cattle-types’), showing the same anatomical characteristics and having a stratified rumen content. One exception was the remarkably smaller omasum observed in blackbucks compared to other ‘cattle-type’ ruminants. The sand gazelle digestive morphophysiology showed both ‘moose-type’ and ‘cattle-type’ characteristics; while some of the characteristics were of an intermediate position between the ranges reported for ‘moose-types’ and ‘cattle-types’. This inconsistency is likely evidence of the sand gazelle being adapted to a diet including both grasses and browse. Overall, all three species investigated deviated in some way from the expectations regarding their digestive tract anatomy and function, thus emphasizing the uncertainty in using a single or a few digestive parameters to predict the feeding style or digestive strategy of a species. The suggested converging digestive morphophysiology of browsing and grazing ruminants do reflect reality, but with several species-specific exceptions. It remains to be investigated if such exceptions can serve to improve our understanding of the functional relevance of a given digestive characteristic, or offer insights into the ecological or phylogenetic history of a certain clade, but it certainly underlines the importance of including phylogeny in investigations of morphophysiological characters. Overall, the findings of this study contribute to a better understanding of the unique digestive strategy of ruminants.

    Linket til højre henviser til rapporten i trykt format til download.This report provides an overview on new technologies for integrate sustainable and resilient management practices in arable ecosystems for advanced farmers, consultants, NGOs and policy makers. By following sustainable soil management strategies, which consider the site- and field-specific parameters and agricultural machinery’s improvements, it is possible to maximize production and income, while reducing negative environmental impacts and human health issues induced by agricultural activities as well as improving food and soil quality in short- and long-terms. This report also illustrates the importance to combine a system approach for plant production by assessing field readiness, managing in-field traffic management, implementing the sitespecific controlled as well as sensor-controlled seedbed preparation, seeding, and weeding. Hence, allowing to estimate future field and crop parameters based on various sensors measurements of previous and current field and crop parameters, which is a required data input in order to optimize agricultural machinery’s performance.
