me first paper on narrow-beam echosounding was published in 1960. Since then, the advantages of the principle of multibeam swath bathymetry for seabed mapping have been recognized by many institutions working in the field of underwater area mapping. We intend to review some of the developments the multibcam cchosoundcr has undergone in order to better understand the challenges facing the field ...

The present study was carried out to characterize the cervical mucus (CM) collected when inseminating Holstein cows and to relate the secretion pattern with pregnancy. The mucus was collected from mid-cervix of 64 cows with spontaneus estrus (SE) and induced estrus (IE). The quantity, pattern and consistency of the mucus, pH, arborization patterns and the sperm motility were observed. The level...

[1] Ontario Lacus is the largest and best characterized lake in Titan’s south polar region. In June and July 2009, the Cassini RADAR acquired its first Synthetic Aperture Radar (SAR) images of the area. Together with closest approach altimetry acquired in December 2008, these observations provide a unique opportunity to study the lake’s nearshore bathymetry and complex refractive properties. Av...

objective(s):emap-like protein 5 (eml5) is a new echinoderm microtubule-associated protein that is expressed in the central nervous system. the aim of this study was to investigate the expression profile of eml5 in the anterior temporal neocortex of patients presenting with intractable epilepsy (ie). materials and methods:western blot assays were performed to determine eml5 expression in 36 sur...

during the epidemiological research of zoonoses, the authors have studied the rabies of wild animals : fox. for the scro lo-uical tests. the blood . was taken by heart puncture of foxes. 193 specimens were tested and 26 (13. 5%) o r the foxes had neut ralizing antibody in their blood. this study confirms that during the rabies epizooty. the vulpin population, may contract a non-fatal disease an...

this article elaborates on the experience of higher medical education evaluation in iran. although institutional evaluation in iran started in about a decade ago, recent policies of the government to increase quality of higher medical education have contributed to a special effort in designing and implementing evaluation mechanisms in university systems in iran. among these a process of interna...

Based on assumptions of an inviscid fluid and weakly rotational flow, a set of depth-averaged governing equations are developed to model long internal waves in two horizontal dimensions. These waves are assumed to be weakly nonlinear and weakly dispersive, existing in a two-layer system with a small density difference between the layers. No restriction is placed on the bathymetry or the dominan...

-Numerical computations of tsunamis are made for the 1992 Nicaragua earthquake using different governing equations, bottom frictional values and bathymetry data. The results are compared with each other as well as with the observations, both tide gauge records and runup heights. Comparison of the observed and computed tsunami waveforms indicates that the use of detailed bathymetry data with a s...

The conformal mapping formulation for the free-surface Euler equations in the presence of non homogeneous, yet stationary bathymetry is here derived and numerically implemented. The differences arising with respect to the more familiar flat-bottom and deep-water versions of the method are examined in detail. It is also shown how the loss of translational invariance due to the variable bottom pr...
