This paper is concerned with the design of reconfigurable antennas based on pure water. Being a transparent, flexible, and readily available liquid, water can form cylindrical stream that be used to guide leaky electromagnetic wave. By properly selecting attenuation phase constants wave, radiation characteristics designed suit different application requirements. controlling flow or size shape w...

Sulfide is an important pollutant in aqueous systems. Sulfide removal from polluted waters is required prior to discharge. Red mud (RM) is a solid waste of bauxite processing that is rich in reactive iron oxides and consequently has the potential to be used to remove sulfide from aqueous systems. A series of experiments was undertaken using raw and sintered RM to remove sulfide from waters. RM ...

Many proteins are not refoldable and also insoluble. Previously no general method was available to solubilize them and consequently their structural properties remained unknown. Surprisingly, we recently discovered that all insoluble proteins in our laboratory, which are highly diverse, can be solubilized in pure water. Structural characterization by CD and NMR led to their classification into ...

Measurements of the magnitude and spectral distribution of the Raman-scattering coefficients of pure water (b(rw)) and seawater (b(rs)) are presented. Two independent measurements of the spectral distribution of the Raman-scattering coefficient of pure water were made for incident wavelengths ranging from 250 to 500 nm. These measurements revealed a strong dependence of b(rw) on wavelength that...

OBJECTIVES There is little information about continued use of point-of-use technologies after disaster relief efforts. After the 2004 tsunami, the Red Cross distributed ceramic water filters in Sri Lanka. This study determined factors associated with filter disuse and evaluate the quality of household drinking water. METHODS A cross-sectional survey of water sources and treatment, filter use ...

 We performed molecular dynamics simulations using the coarse-grained model to study the freezing behavior of pure water and 14% water-salt mixture in a wide range of temperatures for a very long time around 50 nanoseconds. For the salty water, an interface in nanoscale was used. For both systems, the f...

Purpose of this clinical research study was, to determine the efficacy of plain water mixed with pure natural honey, to be used in the inflammation of the kidney (Nephritis) patients. 10 patients aged 18 to 21 years, (4 females, 6 males) with non- sever nephritis were given[three times a day] one standard glass of plain boiled water mixed with 4-table spoons of pure natural honey (Mel) for 14 d...

Seawater-soluble nutrient fractions of aerosols better represent the contribution of aerosol dry deposition to the nutrient load from this source to the ocean than any estimates based on aerosol nutrients leached in pure water or acidic solutions. To understand the solubility difference between seawater and pure water, 31 pairs of aerosol samples collected from the Gulf of Aqaba were extracted ...

A new phase-correction algorithm for three-point Dixon (3PD) MR imaging allows on-line image reconstruction of three images per section: pure water, pure fat, and water plus fat. When combined with fast spin-echo acquisition, the sequence is suitable for routine MR imaging of the retrobulbar space. The 3PD pure water images have double the image signal-to-noise ratio of fast spin-echo inversion...
