OBJECTIVES Our objectives are to measure in the laboratory the way in which waves and sea ice interact, and to compare the results with existing theoretical models, and field and satellite observations. Specifically, we are using laboratory results to determine the role of ocean swell and wind-waves in the growth of sea ice in open water regions such as polynyas, and satellite observations to h...

The unprecedented precision of atom interferometry will soon lead to laboratory tests of general relativity to levels that will rival or exceed those reached by astrophysical observations. We propose such an experiment that will initially test the equivalence principle to 1 part in 10(15) (300 times better than the current limit), and 1 part in 10(17) in the future. It will also probe general r...

limited studies have been done on nematodes of bellamya bengalensis (fresh water snails) in the world. following, our clinical observations on eye disease in a fish ponds, which were contained bellamaya bengallensis snails, present study was made to determine of nematodes fauna of bellamya bengalensis and evaluation of their medical and veterinary importance in khouzestan province. for this pur...

One of the biggest successes of the standard Big Bang cosmology is the prediction of the existence and black body nature of Cosmic Microwave Background (CMB). Observations and measurements of the CMB radiation by COBE (COsmic Background Explorer), WMAP (Wilkinson Microwave Anisotropy Probe) and Planck show an almost isotropic blackbody radiation with temperature TCMB = 2.726 ± 0.010 K (Mather e...

!%" The Vogar Fissure Swarm is one of four en-echelon fracture swarms that connect the !&" Reykjanes Ridge to the South Iceland Seismic Zone and the Western Volcanic Zone. !'" Occurring in an area of flat topography, this fissure swarm is clearly visible at the surface, !(" where it can be seen to affect recent postglacial lavas. Using remote sensing methods to !)" identify and measure all the ...

We introduce new OWL ontologies for observations and sampling features, based on the O&M conceptual model from OGC and ISO 19156. Previous efforts, (a) through the W3C SSN project, and (b) following ISO rules for conversion from UML, had dependencies on elaborate pre-existing ontologies and frameworks. The new ontologies, known as om-lite and sam-lite, remove such dependencies, and can therefor...

Since about 1880, the eggs and sperm of sea urchins have been used for the study of fertilization, the metabolic activation of development and gene regulatory mechanisms governing embryogenesis. Sea urchin gametes are a favorite material for observations of the process of fertilization in advanced high school, community college, and university biology laboratory courses. This article is a labor...
