Strangeness Prospects with the CBM Experiment

The CBM experiment will study strongly interacting matter at high net-baryon densities with nuclear collisions up to 45A GeV beam energy at the future FAIR facility. With interaction rates unprecedented in heavy-ion collisions, CBM will give access also to extremely rare probes and thus to the early stage of the collisions, in search for the first-order phase transition from confined to deconfined matter and the QCD critical point. The CBM physics programme will be started with beams delivered by the SIS-100 synchrotron, providing energies from 2 to 11 GeV/nucleon for heavy nuclei, up to 14 GeV/nucleon for light nuclei, and 30 GeV for protons. The highest net baryon densities will be explored with ion beams up to 45 GeV/nucleon energy delivered by SIS-300 in a later stage of the FAIR project

The Challenges Facing Distance Students in Undertaking Geography Field Practical Projects: The Case of the Open University of Tanzania Students

This paper discusses the challenges facing distance students in Geography field Practical projects (GFPs) at The Open University of Tanzania (OUT). A random sample size of 19 students who participated in GFP1 in 2009 and 2010 were selected from randomly sampled regional centres of Singida, Dodoma, Njombe, and Morogoro centres of OUT. The respondents were interviewed using questionnaires on their experience in GFP. They also formed a focused discussion group (FDG) for this study. Both content analysis and descriptive analysis were used. Findings showed a downward trend of students’ attendance to fieldwork as compared to the early years when GFPs was introduced. The study sample revealed that, in 2006 the four selected regional centres recorded 375 (76.5%) students attended fieldwork out of 490 (100%) students who registered for GFP. In year 2010, only 132 (53.9%) attended out of 245 students who registered for GFP. Besides, 63.2% of the respondents in the study sample said they were supervised in GFP1 under limited time of 2-3 days as supervisors had to leave fieldwork due to time constraint. The paper recommends the urgent need to improve GFP organization, especially adherence to 21 days allocated for GFP and financial support in order to achieve its established objectives and goals at large.Key words: The Open University of Tanzania, Geography field Practical projects, challenges, distance educatio

DN interaction from meson exchange

A model of the DN interaction is presented which is developed in close analogy to the meson-exchange KbarN potential of the Juelich group utilizing SU(4) symmetry constraints. The main ingredients of the interaction are provided by vector meson (rho, omega) exchange and higher-order box diagrams involving D*N, D\Delta, and D*\Delta intermediate states. The coupling of DN to the pi-Lambda_c and pi-Sigma_c channels is taken into account. The interaction model generates the Lambda_c(2595) resonance dynamically as a DN quasi-bound state. Results for DN total and differential cross sections are presented and compared with predictions of an interaction model that is based on the leading-order Weinberg-Tomozawa term. Some features of the Lambda_c(2595) resonance are discussed and the role of the near-by pi-Sigma_c threshold is emphasized. Selected predictions of the orginal KbarN model are reported too. Specifically, it is pointed out that the model generates two poles in the partial wave corresponding to the Lambda(1405) resonance.Comment: 14 pages, 8 figure

Lightweight Thermal Management Strategies for the Silicon Detectors of CBM at FAIR

Lightweight thermal management is central to the design of the all-silicon Inner Tracker of the Compressed Baryonic Matter Experiment (CBM) at the Facility for Antiproton and Ion Research (FAIR). This experiment aims to study strongly interacting matter at neutron star core densities through fixed-target Au-Au collisions ($\sqrt{s_{NN}} = 2.9 - 4.9\,$GeV; up to 10$^7$ beam-target interactions per second; polar angular acceptance of $2.5^{\circ} \leq \Theta \leq 25^{\circ}$). Studies with thermal demonstrators for both the pixel-based Micro Vertex Detector and the strip-based Silicon Tracking System have validated their thermal management strategies, preparing them for series production now and global commissioning in 2028.Comment: 2 pages, 4 figures, Proceedings for 16th Pisa Meeting on Advanced Detectors Submitted to NIM

Anchoring of proteins to lactic acid bacteria

The anchoring of proteins to the cell surface of lactic acid bacteria (LAB) using genetic techniques is an exciting and emerging research area that holds great promise for a wide variety of biotechnological applications. This paper reviews five different types of anchoring domains that have been explored for their efficiency in attaching hybrid proteins to the cell membrane or cell wall of LAB. The most exploited anchoring regions are those with the LPXTG box that bind the proteins in a covalent way to the cell wall. In recent years, two new modes of cell wall protein anchoring have been studied and these may provide new approaches in surface display. The important progress that is being made with cell surface display of chimaeric proteins in the areas of vaccine development and enzyme- or whole-cell immobilisation is highlighted.

Technical Design Report for the CBM : Muon Chambers (MuCh)

This document describes the technical layout and the performance of the Muon Chamber (MuCh) System of the Compressed Baryonic Matter (CBM) experiment at FAIR. The MuCh system is designed to identify muon pairs which are produced in high-energy heavy-ion collisions in the beam energy range from 4 to 40 AGeV. The measurement of lepton pairs is a central part of the CBM research program, as they are very sensitive diagnostic probes of the conditions inside the fireball. At low invariant masses, dileptons provide information on the in-medium modification of vector mesons which is a promising observable for the restoration of chiral symmetry. At intermediate invariant masses, the dilepton spectrum is dominated by thermal radiation from the fireball reflecting its temperature. At invariant masses around 3 GeV/c2, dileptons are the appropriate tool to study the anomalous charmonium suppression in the deconfined phase. In the CBM experiment both electrons and muons will be measured in order to obtain a consistent and comprehensive picture of the dilepton physics
