In this paper a new approach for RGB image encryption is based on a blend of 2D chaotic maps. Chaotic Henon map, chaotic Burger map and chaotic Gingerbreadman map is used in order to meet up the requirements of the protected image transmission. The proposed image encryption scheme is composed of two Transformation processes and two substitution processes. Different statistical methods, such as ...

The superfluidity of Bose-Einstein condensates ~BECs! in optical lattices is investigated. Apart from the usual Landau instability, which occurs when a BEC flows faster than the speed of sound, the BEC can also suffer a dynamical instability, resulting in period doubling and other sorts of symmetry breaking of the system. Such an instability plays a crucial role in the dissipative motion of a t...

Listeria species are widely distributed in environment and L. monocytogenes are the causal agent of Listeriosis, the disease that can be serious and fatal to human and animals. The objectives of this study were to detect, isolate and identify Listeria monocytogenes from retail broiler chicken ready to eat meat products in restaurants-Khartoum state, Sudan. A total of 250 retail broiler chicken ...

In this study, the D-optimal mixture design methodology was applied to determine the optimised proportions of inulin, β-glucan and breadcrumbs in formulation of low-fat beef burgers containing pre-emulsified canola and olive oil blend. Also, the effect of each of the ingredients individually as well as their interactions on cooking characteristics, texture, colour and sensory properties of low-...

Using immunoelectrophoresis, Mackiewicz and Fenrych (1961) found broader and more intense IgM precipitation lines in sera from patients with ankylosing spondylitis (AS). Kriegel, Burger, Kapp, and Alexopulos (1969) determined Ig levels in AS by single-radial immunodiffusion (Mancini, Vaerman, Carbonara, and Heremans, 1964) and reported a rise of the IgA level. Using the same technique, Langness...

Overproduction of date fruits with limited industrial utilization leads to huge waste and losses, especially in bisr (the first stage maturity). Therefore, this study aimed investigate the potential using powder (BDP), which is rich dietary fiber, flavonoids, phenolic antioxidant compounds, as a replacement for breadcrumbs beef burgers. The burger samples were produced by replacing breadcrumb d...
