The history of indentured migration to seventeenth-century English America relies heavily on a single body sources known as the London record, collection contracts and registrations servants who emigrated from capital between 1683 1686. Of original 1,000 contracts, 189 have long been considered be missing. This article uses methods study paperwork print culture demonstrate that Huntington Libra...
Simultaneous capillary dominated displacement of the wetting and non-wetting phases are processes of interest in many disciplines including modeling of the penetration of polluting liquids in hydrology or the secondary migration in petroleum reservoir engineering. Percolation models and in particular invasion percolation is well suited to characterize the slow immiscible displaceme...
In this study, a numerical examination of the significance of rotation and changeable gravitational field on the start of nanofluid convective movement in an anisotropic porous medium layer is shown. A model that accounts for the impact of Brownian diffusion and thermophoresis is used for nanofluid, while Darcy’s law is taken for the porous medium. The porous layer is subjected to uniform rotat...
Through this lecture note we try to provide a portal into the emerging filed of kernelization. We exhibit through examples various tools to prove both lower and upper bounds on the kernel sizes.

Plane wave propagation in infinite two-dimensional periodic lattices is investigated using Floquet-Bloch principles. Frequency bandgaps and spatial filtering phenomena are examined in four representative planar lattice topologies: hexagonal honeycomb, Kagomé lattice, triangular honeycomb, and the square honeycomb. These topologies exhibit dramatic differences in their long-wavelength deformatio...
The thermodynamic problem of a gas of static quarks carrying U(N) charges and interacting with each other via U(N) electric gauge fields is formulated and solved in the large N limit. In a lattice theory, the solution can be found in any dimension. In particular, in 1+1-dimensions, the continuum model can also be solved. In that case, and when the quarks are in the adjoint representation, the e...
The induced 4d gravity on a brane world is analyzed. The case of a thick brane is considered and the unexpected appearance of a new threshold scale, much larger than the thickness scale is found. In cases of phenomenological interest, this new length scale turns out to be in the submillimeter range. The effect of R corrections, both in the bulk and on the brane, is also studied. It is shown tha...
