Laser-assisted atom probe shows a unique potential in the analysis of embedded Si/metal interfaces, owing to its ability to deliver 3D information with atomic resolution. The interface structures in tri-layer specimens Cu/amorphous Si/Cu are investigated by this technique. For amorphous Si (a-Si) deposited on Cu, a sharp transition occurred with an interface width of 2.4 nm. On the contrary, a much broader mixed zone, 5.3 nm wide, is formed when Cu is deposited on top of a-Si. Only in the latter case, brief annealing leads to immediate nucleation of the Cu3Si. Secondary neutral mass spectrometry confirmed independently the existence of this asymmetry in phase formation and demonstrates linear growth kinetics of the silicide. © 2013 WILEY-VCH Verlag GmbH & Co.

Grid-based Massive dataset search systems integrate many processes to search for a large number of shared datasets distributed over several locations. The implementation of the search mechanism to deal with these distributed dataset greatly affected the system performance. However, the execution of the search over the grid requires someone with grid knowledge and expertise. Consequently, this issue leads this research to propose an interface that hides the complexities of the grid operations from the end users. Additionally, the interface provides single sign-on mechanism to allow users to access several Virtual Organizations (VO) with a single user name and a password. The experiment was conducted to evaluate the user interface overhead and the efficiency of the interface. The result shows that the client user interface produces less overhead and is reasonably efficient in dealing with several VOs. © 2015 IEEE.

Cloud computing systems assist applications by offering virtualized resources that can be provisioned on demand basis. Computing resources are delivered by Virtual Machines (VMs). Traditional development models have many limitations such as cost and delay. Platform as services is an effective solution for most of problems on traditional development application model that faced by programmers as Platform as a Service provides them the same traditional features with a faster speed, reducing the cost and increasing collaboration. The aim of this paper is to develop cloud based framework based on Platform as a Services to assist in developing, testing and deploying application without the need to purchase of hardware, operating systems, and tools that is obtainable as services via the Internet. To evaluate the proposed framework, this study conducted an empirical study by setting up an experiment for programmers and IT 'specialists. The achieved results revealed that the proposed framework can overcome the tradition framework limitation © 2015 IEEE.

This study presents mapping of rainfall predictions over Sudan using spatial analysis of climatological data. Geographic Information System ArcGIS provides the means to produce climatological surfaces for the entire Sudan between the years 2000-2012. The temporal resolution of the maps is monthly and annual. Spatial data were obtained from Central Bureau of Statistics Sudan for three levels (towns, states and regions). This study provides a deeper analysis of rainfall phenomenon in Sudan. Monthly and Annual variation in rainfall for 13 years was visualized in rainfall maps. Also analysis been made for rain at the same level for different months. Finally we analyzed rainfall with the most influenced variables such as temperature and relative humidity for different months and levels. Results from this study reveal the ability of GIS to explain and extract general patterns of rain phenomenon and its distribution over different geographical areas in Sudan. © MIR Labs.

Background: Most people exposed to M. tuberculosis show no evidence of clinical disease. Five to 10% of individuals with latent infection progress to develop overt disease during their life time. Identification of people with latent TB infection will increase case detection rates and may dictate new treatment policies to control tuberculosis. This study aimed to determine LTBI point prevalence in a population from Sudan using two different diagnostic methods: the tuberculin skin test (TST) and the IFN-γ release assay (IGRA). Methods. This was a prospective, community-based and case-controlled study. Following informed consent, household contacts (HHCs; n = 98) of smear-positive index cases and Community controls (CCs; 186), were enrolled. Tuberculin skin test (TST), whole blood stimulation with ESAT-6/CFP-10 ± TB7.7 antigens or purified protein derivative (PPD) and IFN-γ levels determination with ELISA were performed. The levels of IFN-γ and TST induration between the CCs and the HHCs were compared using student t-test, Chi-square and Kappa coefficient. Pearson correlation test was used to compare TST and IFN-γ. P levels of <0.05 were considered significant. Results: TST induration of ≥ 10 mm gave an LTBI point prevalence of 327 cases/1000 individuals among HHCs compared to 126 cases/1000 individuals among CCs (p = 0.000). PPD-induced IFN-γ release assay gave an LTBI point prevalence of 418 cases/1000 individuals among HHCs compared to 301 cases/1000 individuals among CCs (p =0.06). On the other hand ESAT-6/CFP-10 ± TB7.7-induced IFN-γ gave an LTBI point prevalence of 429 cases/1000 individuals among HHCs compared to 268 cases/1000 individuals among CCs (p = 0.01). IFN-γ productions levels induced by ESAT-6/CPF-10 ± TB7.7 antigens in HHCS and CCs were not significantly different from those induced by PPD (p = 0.7). Conclusion: IFN-γ release assay (IGRA) gave higher LTBI point prevalence compared to TST in HHCs and CCs. PPD gave comparable results to ESAT-6/CFP-10 ± TB7.7 antigens in whole blood IFN-γ release, making it a cheap alternative to the recombinant antigens. © 2013 Shakak et al.; licensee BioMed Central Ltd.
