the study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. in this study, the propagation of static ...

I survey the first twenty-five years of economic change in the former communist countries after the fall of the Berlin Wall. While diverging sharply from one another, these countries have converged economically and politically towards their nearest neighbors outside the Soviet bloc. The typical country experienced a spurt of economic reform in the early 1990s, slowing dramatically from around 1...

We theoretically study the topography of a biphasic surfactant monolayer in the vicinity of domain boundaries. The differing elastic properties of the two phases generally lead to a nonflat topography of "mesas," where domains of one phase are elevated with respect to the other phase. The mesas are steep but low, having heights of up to 10 nm. As the monolayer is laterally compressed, the mesas...

This paper discusses the design and development of worksheets for helping notebook computer (NBC) users to compute NBC and workstation adjustments so as to assume an appropriate seated posture. The worksheets (one for male users, the other for female ones) require the following information: body height, NBC screen size, work surface height, and seat height. The worksheets contain tables for est...

We investigate experimentally and theoretically the coalescence dynamics of two spreading droplets on a highly wettable substrate. Upon contact, surface tension drives a rapid motion perpendicular to the line of centers that joins the drops and lowers the total surface area. We find that the width of the growing meniscus bridge between the two droplets exhibits power-law behavior, growing at ea...

Distributed space missions can offer significant advantages in cost and complexity over traditional, monolithic spacecraft. The ability of a distributed mission to perform synthetic aperture radar interferometry for the purpose sea surface height monitoring is assessed. A multiobjective genetic algorithm used vary payload distribution, parameters orbital explore impact these on measurement erro...

Land surface temperature (LST) is heavily influenced by urban morphology. Building height an important parameter of morphology that affects LST. Existing studies show contradicting results where building can have a positive or negative relationship with More are necessary to examine the impact height. However, high accuracy data difficult obtain on global scale and not available in many places ...

BACKGROUND/OBJECTIVE Ultrasonogrphy is a good modality for the detection of splenomegaly even when it is not clinically palpable. The objective of this study was to establish the normal values of splenic length in healthy school children in South-East, Nigeria and to correlate them with body indices. MATERIALS AND METHODS This is a cross-sectional prospective study of 1315 children (633 boys ...

Seventy-seven clinically normal children with kidneys of normal size were examined sonographically. Renal parenchymal volumes were calculated and related to age, height, body weight and body surface area; growth charts were constructed. A significant correlation was found between the renal parenchymal volume and the body somatometric parameters. The present report thus provides norms for renal ...
