    Design and fabrication of a data logger for atmospheric pressure, temperature and relative humidity for gas-filled detector development

    Full text link
    A novel instrument has been developed to monitor and record the ambient pa- rameters such as temperature, atmospheric pressure and relative humidity. These parameters are very essential for understanding the characteristics such as gain of gas filled detectors like Gas Electron Multiplier (GEM) and Multi Wire Propor- tional Counter (MWPC). In this article the details of the design, fabrication and operation processes of the device has been presented.Comment: 11 pages, 12 figure

    Detection of hidden structures on all scales in amorphous materials and complex physical systems: basic notions and applications to networks, lattice systems, and glasses

    Full text link
    Recent decades have seen the discovery of numerous complex materials. At the root of the complexity underlying many of these materials lies a large number of possible contending atomic- and larger-scale configurations and the intricate correlations between their constituents. For a detailed understanding, there is a need for tools that enable the detection of pertinent structures on all spatial and temporal scales. Towards this end, we suggest a new method by invoking ideas from network analysis and information theory. Our method efficiently identifies basic unit cells and topological defects in systems with low disorder and may analyze general amorphous structures to identify candidate natural structures where a clear definition of order is lacking. This general unbiased detection of physical structure does not require a guess as to which of the system properties should be deemed as important and may constitute a natural point of departure for further analysis. The method applies to both static and dynamic systems.Comment: (23 pages, 9 figures

    Vertical gardening: For present age environmental protection

    Get PDF
    The term “vertical gardening” is self-explanatory. Vertical gardens, also known as green walls are contemporary forms of gardening. The increase in the urban living and lifestyle has raised the number of apartments in India. This has led to the encroachment of spaces all over the city. For a person who is a nature lover, it is very difficult to have their own garden especially when they are residing in an apartment. Perhaps, they need not lose hope as a vertical garden can let you indulge in gardening and your love towards gardening. You can attain this by cultivating a vertical garden in your apartment balconies or any other appropriate place. This will help create green walls in limited space of your apartment. A vertical garden will give your home a chic look by acting as an elegant home décor as well as it freshens up the air. They can be classically minimal or overgrown based on your preference. Vertical gardens can be mounted on walls using different suitable mediums like bags, pouches, water bottles, plastic containers, fabrics and so on. These gardens can be used to block unpleasant sights or penetrating sunlight in your apartment. With the popularity and versatility of vertical gardening systems, there are now several designs of green-walls on the market for both aesthetic and productive gardens. It’s important to have an understanding of the strengths of each system so you can create the effect you are after, not only for the weeks after installation but in the years to come. A vertical garden performs environmental magic while hiding ugly walls or providing the whole family with an abundance of fresh food but they need to be easy to install and even easier to maintain. They add height to horizontal gardens, making them more visually thought provoking

    Azimuthal correlations of D-mesons in pp+pp and pp+Pb collisions at LHC energies

    Full text link
    We study the correlations of D mesons produced in pp+pp and pp+Pb collisions. These are found to be sensitive to the effects of the cold nuclear medium and the transverse momentum (pTp_T) regions we are looking into. In order to put this on a quantitative footing, as a first step we analyse the azimuthal correlations of D meson-charged hadron(Dh), and then predict the same for D meson -anti D meson (DD‾D\overline{D}) pairs in pp+pp and pp+Pb collisions with strong coupling at leading order O\cal{O}(αs2\alpha_{s}^{2}) and next to leading order O\cal{O}(αs3\alpha_{s}^{3}) which includes space-time evolution (in both systems), as well cold nuclear matter effects (in pp+Pb). This also sets the stage and baseline for the identification and study of medium modification of azimuthal correlations in relativistic collision of heavy nuclei at the Large Hadron Collider.Comment: 12 pages, 4 figure
