We present a lattice model of water confined in a hydrophobic nanotube. Using analytical methods and computer simulation, we find conditions where filled and empty tubes can be degenerate in equilibrium. We further find that flow of water molecules through a filled tube with appropriate but simple stochastic rules can be interpreted as water conduction in a pulse-like fashion. These two results...

Analysis of soil samples collected from sewage and tube well irrigated soils of Ludhiana, Amritsar Jalandhar and Mandi Gobindgarh, revealed that Diethylene triamine pentaacetic acid extractable nickel ( DTPA-Ni) was found to be higher in sewage fed soils. Sewage irrigation increased soil DTPA-Ni content by 3.04 times over the tube well irrigated soils. The content of DTPA-Ni showed decreasing t...

The analysis of crosswell seismic data for a gas reservoir in Texas revealed two newly detected seismic wave effects, recorded 2000 feet above the reservoir. The first is that the dominant late phases on the records are the tube waves generated in the source well and later converted into laterally propagating waves through the reservoir in gas/water saturated layers, which convert back to tubew...

Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 14, No. 9, September 2008 1499 Most of the patients whose cases were diagnosed in Buenos Aires, including 5 who required hospitalization, were referred to Muñiz Hospital. Built a century ago, Muñiz Hospital comprises a number of independent pavilions surrounded by a spacious garden, where mosquitoes thrive, especially in summer. Thus, vector...

THIS work is an attempt to investigate the eflfects of various atmospheric humidities on the death points of insects at high temperatures. A number of species of insects were used, and an attempt made to correlate the results with those of previous workers. The apparatus used was similar in essentials to that previously used by Beattie (1928) and by Buxton (1931 b). It is shown in Fig. 1. The w...

A case study was carried out to see the impacts of shrimp culture on the surface (pond) and ground water (tube-well) quality in three coastal sub-districts of Bagherhat Sadar, Rampal and Morrelganj of Bangladesh. The people of Rampal (100%), Morrelgonj (87.5%) and Bagherhat (75.5%) expressed that salinity of both surface and ground water increased after shrimp culture, and water becomes more tu...

This research article highlights Omega type Coriolis Mass Flow Sensor (CMFS) used for measuring direct mass flow. CMFS works on the principle of Coriolis effect. In this research article omegatype, CMFS has been investigated for evaluatingresonant frequency. Modelling of CMFS can be split into two domainsstructural and fluid. The omega shaped tube, forming the structural part and the fluid flow...

This experimental study investigated the back pressure (P(back)) versus flow (U) relationship for 10 different tubes commonly used for semi-occluded vocal tract exercises, that is, eight straws of different lengths and diameters, a resonance tube, and a silicone tube similar to a Lax Vox tube. All tubes were assessed with the free end in air. The resonance tube and silicone tube were further as...

Capillary chromatography for the separation of optical isomers was developed using an untreated poly(tetrafluoroethylene) capillary tube and a water-hydrophilic/hydrophobic organic solvent mixture as a carrier solution. The open tubular capillary was 110 cm in length (90 cm effective length) and 100 microm in inner diameter. The carrier solution was prepared with a water-acetonitrile-ethyl acet...
