Nine new species of Caenis from Angola are described herein: Caenis wegeneriana sp. n. (imago), Caenis angolensis sp. n. (imago and larva), Caenis branchiata sp. n. (larva), Caenis ...filappendicessp.n.(imago),Caenisulesisp.n.(larva),Caeniscubangosp.n.(larva),Caenisarmata sp. n. (imago), Caenis brevispinata sp. n. (imago), and Caenis gallocristata sp. n. (imago). The relationship between the newly described species and other known African species is discussed. The vicariant biogeographic affiliation of Caenis wegeneriana to a related species group in South America, separated by continental drift, is considered. A key to the male imagoes is provided, including Caenis antelucanaMalzacher, 1990, Caenis brevipes Kimmins, 1956, Caenis douglasiMalzacher, 1993 and Caenis jinjana Kimmins, 1956, which have previously been recorded in the Cunene River, along the shared border with Namibia.

The FairRoot framework is an object oriented simulation, reconstruction and data analysis framework based on ROOT. It includes core services for detector simulation and offline analysis. The ...framework delivers base classes which enable the users to easily construct their experimental setup in a fast and convenient way. By using the Virtual Monte Carlo concept it is possible to perform the simulations using either Geant3 or Geant4 without changing the user code or the geometry description. Using and extending the task mechanism of ROOT it is possible to implement complex analysis tasks in a convenient way. Moreover, using the FairCuda interface of the framework it is possible to run some of these tasks also on GPU. Data IO, as well as parameter handling and data base connections are also handled by the framework. Since some of the experiments will not have an experimental setup with a conventional trigger system, the framework can handle also free flowing input streams of detector data. For this mode of operation the framework provides classes to create the needed time sorted input streams of detector data out of the event based simulation data. There are also tools to do radiation studies and to visualize the simulated data. A CMake-CDash based building and monitoring system is also part of the FairRoot services which helps to build and test the framework on many different platforms in an automatic way, including also Continuous Integration.
The new mayfly species Caenis albicans sp. n. and Caenis letabanensis sp. n. (Ephemeroptera: Caenidae) from the Kruger National Park, South Africa, are described herein. The new species were ...collected in the area of the confluence of the Olifants and Letaba Rivers. They belong to the Caenis – TPA group, a group widely distributed in Africa, characterised inter alia by forceps apically having a tuft of long spines. The material examined also contained samples from the Crocodile and Sabie Rivers, with larvae and imagines of Caenis brevipes Kimmins, 1956. The previously unknown larva of this species is also described.

Due to conceptual difference between geometry descriptions in Computer-Aided Design (CAD) systems and particle transport Monte Carlo (MC) codes direct conversion of detector geometry in either ...direction is not feasible. The paper presents an update on functionality and application practice of the CATIA-GDML geometry builder first introduced at CHEP2010. This set of CATIAv5 tools has been developed for building a MC optimized GEANT4/ROOT compatible geometry based on the existing CAD model. The model can be exported via Geometry Description Markup Language (GDML). The builder allows also import and visualization of GEANT4/ROOT geometries in CATIA. The structure of a GDML file, including replicated volumes, volume assemblies and variables, is mapped into a part specification tree. A dedicated file template, a wide range of primitives, tools for measurement and implicit calculation of parameters, different types of multiple volume instantiation, mirroring, positioning and quality check have been implemented. Several use cases are discussed.
Due to conceptual difference between geometry descriptions in Computer-Aided Design (CAD) systems and particle transport Monte Carlo (MC) codes direct conversion of detector geometry in either ...direction is not feasible. An original set of tools has been developed for building a GEANT4/ROOT compatible geometry in the CATIA CAD system and exchanging it with mentioned MC packages using GDML file format. A Special structure of a CATIA product tree, a wide range of primitives, different types of multiple volume instantiation, and supporting macros have been implemented.
Based on SEM pictures the different evolutionary stages of shape and arrangement of microtrichia on the ventral side of the operculate gills (gill cover) in Caenidae are shown. There are a number of ...tendencies that can be observed in the evolution of these structures. The presence of different evolutionary stages of these structures in the Caeninae, Madecocercinae, and the newly postulated Clypeocaenis group is discussed and parallel developments in these taxa are assumed.
Larvae of two new genera of Caenidae are described from the River Niandan, Guinea. Their position in the phylogenetic system of Caenidae is discussed. Niandancus alienus gen. n., sp. n. is the first ...known representative of the Brachycercinae in the Ethiopic region. Aenigmocaenis morgensterni gen. n., sp. n. could represent the sister group to all other Caenidae, as the most important larval synapomorphy of the family, a band or row of microtrichia on the ventral side of the operculate gill, is lacking.
Using the gLitePROOF package it is possible to perform PROOF-based distributed data analysis on the gLite Grid. The LHC experiments managed to run globally distributed Monte Carlo productions on the ...Grid, now the development of tools for data analysis is in the foreground. To grant access interfaces must be provided. The ROOT/PROOF framework is used as a starting point. Using abstract ROOT classes (TGrid, ) interfaces can be implemented, via which Grid access from ROOT can be accomplished. A concrete implementation exists for the ALICE Grid environment AliEn. Within the D-Grid project an interface to the common Grid middleware of all LHC experiments, gLite, has been created. Therefore it is possible to query Grid File Catalogues from ROOT for the location of the data to be analysed. Grid jobs can be submitted into a gLite based Grid. The status of the jobs can be asked for, and their results can be obtained.
