Direct nanofiltration (NF) of secondary treated effluent can significantly simplify water recycling, especially for small scale operations. This study evaluated the performance a novel flat-sheet submerged NF membrane module at low flux to minimize fouling. The separation system was assessed by periodically measuring color, turbidity, pH, UV light absorbance wavelength 254 nm, and total organic...

A cost-effective, reusable practice eye model for epiretinal membrane peeling that uses easily obtained, commercially available materials was developed. A commercially available globe that is anatomically and optically similar to the human eye was modified by creating 2 ports that simulate superior sclerotomies. The model has a removable plastic anterior segment, which allows access to the post...

Experimental investigations were carried out on removal of arsenic from contaminated groundwater by employing a new flat-sheet cross flow membrane module fitted with a hydrophobic polyvinylidenefluoride (PVDF) microfiltration membrane. The new design of the solar-driven membrane module in direct contact membrane distillation (DCMD) configuration successfully produced almost 100 per cent arsenic...

In this study, polyvinylidene fluoride (PVDF) flat membranes were treated with potassium hydroxide (KOH), sodium hydroxide (NaOH) and sodium hypochlorite (NaOCl). The effects of temperature, treatment duration and chemical concentration towards the properties of PVDF membrane were contrastively studied. Following treatment, membrane became much brittle with a reduced nominal elongation to as lo...

Cellular membranes can take on a variety of shapes to assist biological processes including endocytosis. Membrane-associated protein domains provide a possible mechanism for determining membrane curvature. We study the effect of tethered streptavidin protein crystals on the curvature of giant unilamellar vesicles (GUVs) using confocal, fluorescence, and differential interference contrast micros...

dually flat finsler metrics form a special and valuable class of finsler metrics in finsler information geometry,which play a very important role in studying flat finsler information structure. in this paper, we prove that everylocally dually flat generalized randers metric with isotropic s-curvature is locally minkowskian.

let r be a commutative noetherian ring. we study the behavior of injectiveand at dimension of r-modules under the functors homr(-,-) and -×r-.

The purpose of inve fundamental materi field-controlled spe essential for industr such as: membrane windows for sensor spectroscopes, cam flat-panel displays, on the quantum-dot sensitive Stark and excitonic state of or optical adaptability tasks are the develo article and test data smart active optics functional capabilit

Large-area transmission dynodes were fabricated by depositing an ultra-thin continuous film on a silicon wafer with 3-dimensional pattern. After removing the silicon, corrugated membrane enhanced mechanical properties was formed. Mechanical materials, such as this membrane, are engineered to improve its strength and robustness, which allows it span larger surface in comparison flat membranes wh...

We study the Casimir effect of a membrane embedded in 2+1 dimensions flat cone generated by massive particle located at origin coordinate system. The is an exact solution nonprojectable Hořava theory, similar to general relativity. consider scalar field satisfying Dirichlet boundary conditions, and regularize spectrum using ζ–function technique. In addition, we include effects temperature our a...
