    A revision of the Old World Black Nightshades (Morelloid clade of Solanum L., Solanaceae)

    The Morelloid clade, also known as the black nightshades or ?Maurella? (Morella), is one of the 10 major clades within Solanum L. The pantropical clade consists of 75 currently recognised non-spiny herbaceous and suffrutescent species with simple or branched hairs with or without glandular tips, with a centre of distribution in the tropical Andes. A secondary centre of diversity is found in Africa, where a set of mainly polyploid taxa occur. A yet smaller set of species is found in Australasia and Europe, including Solanum nigrum L., the type of the genus Solanum. Due to the large number of published synonyms, combined with complex morphological variation, our understanding of species limits and diversity in the Morelloid clade has remained poor despite detailed morphological studies carried out in conjunction with breeding experiments. Here we provide the first taxonomic overview since the 19th century of the entire group in the Old World, including Africa, Asia, Australia, Europe and islands of the Pacific. Complete synonymy, morphological descriptions, distribution maps and common names and uses are provided for all 19 species occurring outside the Americas (i.e. Africa, Asia, Australia, Europe and islands of the Pacific). We treat 12 species native to the Old World, as well as 7 taxa that are putatively introduced and/or invasive in the region. The current knowledge of the origin of the polyploid species is summarised. A key to all of the species occurring in the Old World is provided, together with line drawings and colour figures to aid identification both in herbaria and in the field. Preliminary conservation assessments are provided for all species.Fil: Sarkinen, T.. University Of Edinburgh; Reino UnidoFil: Poczai, P.

    A comparison of tree- and line-oriented observational slicing

    Get PDF
    Observation-based slicing and its generalization observational slicing are recently-introduced, language-independent dynamic slicing techniques. They both construct slices based on the dependencies observed during program execution, rather than static or dynamic dependence analysis. The original implementation of the observation-based slicing algorithm used lines of source code as its program representation. A recent variation, developed to slice modelling languages (such as Simulink), used an XML representation of an executable model. We ported the XML slicer to source code by constructing a tree representation of traditional source code through the use of srcML. This work compares the tree- and line-based slicers using four experiments involving twenty different programs, ranging from classic benchmarks to million-line production systems. The resulting slices are essentially the same size for the majority of the programs and are often identical. However, structural constraints imposed by the tree representation sometimes force the slicer to retain enclosing control structures. It can also “bog down” trying to delete single-token subtrees. This occasionally makes the tree-based slices larger and the tree-based slicer slower than a parallelised version of the line-based slicer. In addition, a Java versus C comparison finds that the two languages lead to similar slices, but Java code takes noticeably longer to slice. The initial experiments suggest two improvements to the tree-based slicer: the addition of a size threshold, for ignoring small subtrees, and subtree replacement. The former enables the slicer to run 3.4 times faster while producing slices that are only about 9% larger. At the same time the subtree replacement reduces size by about 8–12% and allows the tree-based slicer to produce more natural slices

    The alternative of green open space management in Jakarta City, Indonesia

    Get PDF
    At the present time, the application of policy management of urban green open space of Jakarta have many weakness that caused by overlapping management. There are three institutions of management of urban green open space, those are Park Service (Dinas Pertamanan),, Forest Service (Dinas Kehutanan),, and Agricultural Service (Dinas Pertanian), which are all of them are under the scope of local government of DKI Jakarta. The management consists of several basic activities, including planning and controlling, organizing, human resources, coordination and financing. The prominent indicator associated with the managing urban green open space that related to the aspect of "market failure", it is commonly indicated by public goods, asymmetry of information, externality and aspect of “government failure”. It is also indicated by problems lingered around regulation of law, bureaucracy and bureaucrat agent. The core of the main problems in the policy of management formulation of urban green open space in Jakarta is the lack of managements" of urban green open space of DKI Jakarta. This was indicated by variety of critics coming from the members of society in DKI Jakarta about the function of it, where it will result the impact of environment.In the relation to that problem, there are two questions raised: a. What caused the management of the urban green open space in DKI Jakarta unsuccessful? b. What kind of factors that hampered the management of the urban green open space? As the follow up of the questions above is giving the alternatives to solve that hampered, then, the question is, How is the policy alternative to solve the lack of management of the urban green open space in DKI JakartaThe objective of study is getting the policy to manage the urban green open space in DKI Jakarta. The reflecting of the objective above was explained in the set of policy such as in the regulation and the institutional

    P2P overlay over Simctl

    Get PDF
    This project intends to find and implement a p2p overlay over the simctl platform. Simctl is used both for teaching and research in the network engineering department.P2P systems became an interesting area since early 2000. Researchers conducted a large amount of research in some challenging areas and, to check their experiments, several implementations and simulators were created. Over time, Internet has evolved and P2P has been widely used for file sharing, but the main structured P2P overlays were progressively abandoned. However, these overlays are still taught in network engineering courses. The aim of this master thesis is to find and implement a p2p overlay over the \texttt{simctl} platform, used both for teaching and research in the network engineering department. First, it is tried to locate and test the original structured P2P overlays source codes developed by the authors of the original publications. Then, several available P2P implementations developed by researchers and users have been tested. Once the software was selected, different scenarios for \texttt{simctl} were developed. Finally, a lab session was created by using the previous scenarios
