Abstract— In recent days the demand for river sand is increasing due to its lesser availability. Hence the practice of replacing river sand with M-Sand is taking a tremendous growth. It is also inferred from the literature that replacement of normal sand with M-Sand produces no appreciable increase in compressive strength due to the variation in the pore size of concrete at micro level. This pa...

A total of 90 Pyrus pyrifolia cultivars from southeastern China and Japan were used to assess genetic diversity and overall similarity using eight Amplified Fragment Length Polymorphism (AFLP) primer combinations. Eighty-eight percent of the 429 bands produced were polymorphic. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) cluster analysis of these data support two major groups, mos...

Sediment deprivation from dam installments contributes to beach erosion yet the underlying physical and economic factors linking them together have traditionally been isolated during regional planning. In order to gain a better understanding of the behavior of a managed beach system, a dynamic simulation model was developed incorporating physical and monetary factors influencing the amount of a...

Sandstorm has an effect on the electric field characteristics of outdoor insulator, and may result in flashover. The analysis of the electric field characteristic of insulator under sandstorm condition is very important. The electrostatic field finite element method (FEM) is used to calculate the electric field distribution along long rod insulator under sandstorm condition with FEM software. T...

This study simultaneously varied experiences of recent victory or defeat, 2-hour familiarity with the meeting place, and hen weight in order to understand their combined effects on the establishment of dyadic dominance relationships between hens not previously acquainted with each other. Three kinds of encounters were arranged: (i) a previous winner unfamiliar with the meeting place met a previ...

a telephone trumpet t. When the primary circuit is closed, the enclosed iron bar d becomes magnetised, and in its turn it magnetises the smaller bar b. Secondary currents are thus induced in the fine coil around b. It will be observed that the prolonged axis of d cuts b at its middle ; two secondary currents of equal strength and running in opposite directions are thus induced in the fine coil ...

Martin Kirschner cirujano alemán que empleó por primera vez alambres para la fijación de las fracturas, éstos en la actualidad son de uso frecuente en el tratamiento ortopédico, también desarrolló un abordaje para rodilla, cirugías en las extremidades, así como un método para realizar un esófago artificial, él fue primero en realizar una embolectomía de la arteria pulmonar llamada operación de ...

Polygonal subdivisions, i.e. the representation of categorical data in the vector model, are a common data type in GIS applications, in thematic maps, in topographic maps and in digital landscape models. Their cartographic generalization is termed polygon generalization. Cartographic generalization or generalization is one of the basic principles of cartography, namely the legible and comprehen...
