We review and extend results for mutation, selection, genetic drift, and migration in a onedimensional continuous population. The population is described by a continuous limit of the stepping stone model, which leads to the stochastic Fisher-Kolmogorov-Petrovsky-Piscounov equation with additional terms describing mutations. Although the stepping stone model was first proposed for population gen...

We treated 97 patients with staghorn calculi by ESWL monotherapy using a Lithostar Lithotriptor (Siemens) between January 1989 and December 1996. Seventeen patients (18 renal units) out of 45 patients (47 renal units) who could be followed up for more than 12 months after ESWL had no stones on radiographs at 3 months after the treatment. The actuarial non-recurrence (or stone-free) rate was 88....

Effect of various washing process on the properties of indigo dyed four-way stretch denim fabric was studied in this research. The different washing techniques (Dark washenzymatic treatment, Medium washenzymatic treatment with pumice stone, Bleach washenzymatic treatment with bleaching powder and pumice stone, Acid Wash-Enzymatic treatment with potassium permanganate and pumice stone) were appl...

Themain aim of this paper is to provide a construction of the Banaschewski compactification of a zero-dimensional Hausdorff topological space as a structure space of a ring of ordered field-valued continuous functions on the space, and thereby exhibit the independence of the construction from any completeness axiom for an ordered field. In the process of describing this construction we have gen...

We analyze a well known type of puzzle in planar geometry: given a planar shape, it is required to find a cut that divides the shape into two identical parts (up to rotation and translation). Clearly not all shapes can be so dissected and for some shapes that appear in puzzles the cutting curve is quite surprising and difficult to find. In this paper we first analyze the inverse problem of asse...

The preservation, documentation, and transmission of archaeological artifacts, which are also defined as heritage, can be accepted the common responsibility humanity. To document cultural status historical artifacts should known. photogrammetry technique has been commonly used in documentation heritage parallel with technological developments recently. In addition to producing map topographic p...

Geosynthetic encased stone columns are often designed using the conventional framework of saturated soils ignoring influence in-situ unsaturated soil conditions. This article evaluates performance with and without geosynthetic encasement extending mechanics ofunsaturated soils. The focus numerical simulations was directed towards understanding matric suction on confining support offered by surr...

The paper deals with the development of a dimensional rock sawing machine to optimize production small-volume stone products in limestone quarries by re-thinking use and transport equipment. A low-volume mining transportation adapter be developed for both can reduce number machines used mine. After cutting around block stone, material moved help machine. Cutting tests were performed determine w...
