1 A multi-year study in the Sacramento-San Joaquin Delta system was carried out to exam2 ine the relationship between the survival of out-migrating Chinook salmon Oncorhynchus 3 tshawytscha and the amount of water exported from the system by the two major pumping 4 stations in the southern portion of the Delta. Paired releases of groups of coded-wire-tagged 5 juvenile late-fall run Chinook salm...

serovar isolated from a canal in Louisiana in 1978 revealed it to be identical to that of V. cholerae 01 isolated in 1905 from a pilgrim at the El Tor quarantine station. The two strains are associated with sharply contrasting habitats. Ranges of variation of 5 to 15% in procaryotic 5S rRNA sequences between species are typical; variation within species may be 2% or greater. Because the 5S rRNA...

This empirical analysis examines the use of the live-streaming application Periscope in three crises that occurred in 2015. Qualitative and quantitative analyses of tweets relating to the Amtrak derailment in Philadelphia, Baltimore protests after Freddie Grey’s death, and Hurricane Joaquin flooding in South Carolina reveal that this recently deployed application is being used by both citizens ...

It has been determined that the reduction of siltation front chamber is necessary because deposited sediments seriously violate planned hydraulic structure flow when water sucked up by pumps, as a result which their efficiency decreases. The method calculating pipeline system new device designed to significantly reduce irrigation pumping stations artificially creating turbulence in bottom layer...

freshwater lens on small islands may easily be overexploited or polluted due to overdrafts of fresh water by pumping which causes drawdown of the water table a rise or up-coning of the saltwater interface. present study is concerned with using a three-dimensional finite-difference numerical model to simulate the groundwater flow and transport model to predict the behavior of groundwater system ...

in order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. to do this we have investigated optical waveguide both with and without optical pumping. the rate of absorption and emission using an array of algaas/gaas quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. by con...

In August 2007, several horses showed pyrexia and respiratory signs while in post-arrival quarantine in Australia. Subsequent investigations diagnosed equine influenza by serology and PCR in two quarantine stations. A common origin in a shipment of horses from Japan was indicated.

This paper deals with a theoretical investigation of heat and mass transfer with thermal radiation analysis on hydromagnetic peristaltic Prandtl fluid model with porous medium through an asymmetric tapered vertical channel under the influence of gravity field. Analytical results are found for the velocity, pressure gradient, pressure rise, frictional force, temperature and concentration. The in...

The performance of most urban drainage systems is adversely affected by unintended connections groundwater and surface water, often denoted as inflow infiltration (I&I). Various methods exist to locate characterise these effects. Yet, it remains difficult quantify them accurately, especially in terms spatial distribution over a larger area. One the reasons for this lack sufficient high-qual...
