Physical, structural, and electromagnetic properties and interrelating processes in sea ice are used to develop a composite model for polarimetric backscattering signatures of sea ice. Physical properties of sea ice constituents such as ice, brine, air, and salt are presented in terms of their effects on electromagnetic wave interactions. Sea ice structure and geometry of scatterers are related...

This study assessed the performance of a bioluminescent bacterial assay, the ToxScreen-II Test (Photobacterium leiognathi), in comparison to the brine shrimp (Artemia franciscana) nauplii lethality assay for the detection of toxicity associated with Aloe vera leaf gel extract and the organophosphate pesticide Mevinphos. In both bioassays, clear dose-response relationships were demonstrated for ...

BACKGROUND In South African traditional medicine, some are plants known to combat pediatric diseases and are commonly used by traditional healers. The aim was to evaluate cytotoxicity effects of plants. MATERIALS AND METHODS The ground plant material was exhaustively extracted using methanol, acetone and water separately for 72 hrs. These organic solvents were removed from filtrates using a r...

Relative Permeability Experiments of Carbon Dioxide Displacing Brine & Their Implications for Carbon Sequestration

A small concentration of organic acid in carbon dioxide (CO2) storage formations and caprocks could significantly alter the wettability such into less water-wet conditions, decreasing CO2-storage potential containment security. Recent studies have attempted to infer influence on rock–CO2–brine systems by measuring advancing receding contact angles. However, no investigated contamination capacit...

Mass transfer processes in meat brining can be enhanced by taking advantage of the effects produced by high intensity ultrasound. Pork loin slices were immersed in a saturated solution of NaCl at 2 oC during 45 minutes. Different conditions of agitation of the solution and different levels of ultrasound intensity were applied during brining. Ultrasounds were applied with a probe system and the ...

OBJECTIVE To investigate the toxicity of methanol extract of various parts (Root, Stem, Leaf, Flower and Fruit) of Lantana camara (L. Camara) in Artemia salina. METHODS The methanol extracts of L. camara were tested for in vivo brine shrimp lethality assay. RESULTS All the tested extract exhibited very low toxicity on brine shrimp larva. The results showed that the root extract was the most...

phytochemical screening, antibacterial and cytotoxic activities of petroselinum crispum leaves grown in oman.petroselinum crispum belongs to the apiaceae family, is a well-known spice and vegetable. the essential oil obtained from the fruit has also strong action on the central nervous system. present study is designed to evaluate the phytochemical screening, antibacterial and cytotoxic activit...

Benthic organisms and substrates in the Great Salt Lake, Utah, were sampled during one week in June 2006 to test collection methodologies for biostromes and soft substrates and to get preliminary information on the selenium concentrations of benthic organisms. The sampling was focused on biostromes, as these solid reef-like structures cover 23% of the oxic benthic area of the lake and are the p...

This paper discusses a new nuclear magnetic resonance (NMR) method that can provide wettability, saturation, and oil viscosity values in rocks partially saturated with oil and brine. The method takes advantage of two new technological advances in NMR well logging—the MRF* Magnetic Resonance Fluid Characterization Method and NMR “diffusion-editing” (DE) pulse sequences. We discuss the principles...
