Satellite imagery, synoptic-scale analyses and automatic weather station data were used to study a subsynoptic-scale cyclone that developed over the Ross Sea and Ross Ice Shelf areas of Antarctica. A pre-existing subsynoptic-scale midtropospheric cyclone descended from southern Victoria Land into the semi-permanent baroclinic environment over the south-western corner of the Ross Sea. The subsyn...

Animal origin foods are widely distributed and consumed around the world due to their high nutrients availability but may also provide a suitable environment for growth of pathogenic and spoilage microorganisms. Nowadays consumers demand high quality food with an extended shelf life without chemical additives. Edible films and coatings (EFC) added with natural antimicrobials are a promising pre...

For 11 days in January 2001, the Conrad Blucher Institute for Surveying and Science, Texas A&M UniversityCorpus Christi, in collaboration with the College of Marine Science, University of South Florida, deployed a pair of 25MHz CODAR Ocean Systems HF-Radars on the West Florida Shelf over an array of six acoustic Doppler current profilers. The radar footprint had a maximum range of 60 km offshor...

a stratigraphic section from the tirgan formation was selected in arkan village nearby bojnourd city in order to study echinoderm fauna systematically. many specimens of echinoderms, especially toxasteridae which is associated with brachiopods were collected and studied systematically in this paper. microscopie slides were also prepared and studied. all slides contain benthic foraminifers and c...

The problem of integrated production and maintenance control unreliable manufacturing systems evolving in a stochastic dynamic environment is studied this paper. considered system subject to degradation the produced products are perishable with random shelf-lives. literature operations management for reports correlation between shelf-life product machine degradation. In fact, latter results she...

An active sonar system is used to image wide areas of the continental shelf environment by long-range echo sounding at low frequency. The bistatic system, deployed in the STRATAFORM area south of Long Island in April-May of 2001, imaged a large number of prominent clutter events over ranges spanning tens of kilometers in near real time. Roughly 3000 waveforms were transmitted into the water col...

the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...

This study utilizes more than a year of observations made in shallow waters ( 30 m) at the head of the Monterey Submarine Canyon to assess variability in the physical environment and internal bore field. The interaction of the internal tide with the canyon rim results in a semidiurnal tidal period pumping of cold–water masses (subthermocline waters) onto the adjacent shelf (i.e., internal bores...

we examined the effectiveness of intermittent warming (iw), hot water (hw), salicylic acid (sa), and calcium chloride (cacl2) on the postharvest life of pomegranate fruit cv. ‘shishe-kab’ and extending fruit shelf life during cold storage (3°c). fruit were subjected to cycles of 1 d at 17 ± 1°c every 6 d of storage at 3°c under iw conditions. pre-storage treatments were hw (50°c) for 3 min, sa ...
