  • Nanoformulated rosemary extract impact on oral cancer: in vitro study

    • Authors: Ellithy, Marwa Mohamed;  Advisor: -;  Participants: Aly, Riham Mohamed; Tarek, Heba El-Sayed (2022)

  • Rosemary nanoparticles composite characterization Transmission electron microscope (TEM) informed us on the particle shape as well as their size. TEM micrographs of these nanoparticles are shown in Fig. 1. Electron microscopy analysis confirmed the presence of nanoparticles. RE-loaded chitosan nanoparticles were found to be spherical, distinct and regular with a size of 0.5 µm to 200 nm. Their surface is solid and has a dense structure. Chitosan nanoparticles appeared aggregated in the photomicrographs. The RE particles were well coated by chitosan. The particle size of the prepared nanoparticles ranged from 0.5 µm to 200 nm with an average size of 100 nm.

  • Narrative of the annotated Space – Time Cube – revisiting a historical event

    • Authors: Kveladze, I.; Kraak, M.J.;  Advisor: -;  Participants: - (2017)

  • The Space–Time Cube (STC) is a suitable representation to display multiple characteristics of movement data and will especially reveal temporal patterns in the data. By adding annotations to the cube’s paths and stations, the narrative of the display is enhanced. To illustrate the STC’s storytelling capabilities, a historical event, Napoleon’s crossing of the Berezina River during his Russian campaign in 1812 is presented and linked to an event in 2012 when the authors made a similar trip. Also, a set of different visual queries and their results are presented, emphasizing the STC as an alternative addition to a more extended visualization environment.

  • National fuel type mapping methodology using geographic object based image analysis and landsat 8 oli imagery.

    • Authors: Tompoulidou, M.;  Advisor: -;  Participants: - (2016)

  • A key issue in modern fire management planning is the accurate fuel type mapping, required at many different spatial and temporal scales. Fuel type classification is critical for improving fire prevention schemes, developing accurate fire dispersion models and designing effective measures for mitigating the impacts of a potential wildfire event on the ecosystem. Remote sensing offers the potential to provide spatially distributed information on fuel types and it has been widely used both at regional and local scale. The aim of this study is to develop and evaluate a fuel type mapping methodology on a national level, based on the geographic objectoriented classification approach and La...

  • Native bacteria for field biocontrol of black root rot in Egyptian strawberry

    • Authors: Abd-El-Kareem, Farid;  Advisor: -;  Participants: Elshahawy, Ibrahim E.; Abd-Elgawad, Mahfouz M. M. (2022)

  • Increasing cultivation of strawberry in Egypt has boosted efforts to increase its yield. Biocontrol agents (BCAs) may avoid side effects and health risks caused by chemical fungicides used to control black root rot disease in strawberry. Some BCAs control the disease and augment strawberry yield, but additional research is needed to fit BCAs into emerging control strategies. The impact of six bacterial isolates of Paenibacillus polymyxa and Bacillus brevis on this disease and on berry yield is reported and compared to a common chemical fungicide.

  • Natural anti-inflammatory terpenoids in Camellia japonica leaf and probable biosynthesis pathways of the metabolome

    • Authors: Majumder, Soumya;  Advisor: -;  Participants: Ghosh, Arindam; Bhattacharya, Malay (2020)

  • A total of twenty-nine anti-inflammatory compounds, occupying 83.96% of total area, came out in the result. Most of the metabolites are terpenoids leading with triterpenoids like squalene, lupeol, and vitamin E. In this study, the candidate molecules responsible for anti-inflammatory activity were spotted out in the leaf extract and biosynthetic relation or interactions between those components were also established.

  • Natural freeze-thaw cycles may increase the risk associated with Salmonella contamination in surface and groundwater environments

    • Authors: Rocard, J.M.;  Advisor: -;  Participants: Asadishad, B.; Samonte, P.R.V.; Ghoshal, S.; Tufenkji, N. (2018)

  • We investigated the influence of temperature fluctuations around the freezing point, known as freeze-thaw (FT), on the inactivation rates, growth, and biofilm formation of a manure-isolated strain of Salmonella typhimurium. Moreover, the effects of FT on the transport characteristics of S. typhimurium in quartz sand were monitored in model porewater solutions of two different ionic strengths (IS: 10 and 100 mM KCl) and two different humic acid (HA) concentrations (1 and 5 mg/L). Increasing numbers of FT cycles were found to decrease the deposition of S. typhimurium onto quartz sand and increase the percentage of detached cells in sand-packed column experiments. Based on the calculated...
