INTRODUCTION Hormonal fluctuation is responsible for worsening of epileptic seizures during the menstrual cycle. OBJECTIVE To identify irregularities in the menstrual cycles of women with mesial temporal lobe epilepsy (MTLE) and extratemporal focal epilepsy (ETFE) and correlate the frequency of seizures during the menstrual cycles. METHOD We evaluated prospectively women in the menacme with...

A new kind of hollow fiber surface plasmon resonance sensor (HF-SPRS) based on the silver-coated ethylene tetra-fluoro-ethylene (ETFE) hollow fiber (HF) is presented. The ETFE HF-SPRS is fabricated, and its performance is investigated experimentally by measuring the transmission spectra of the sensor when filled by liquid sensed media with different refractive indices (RIs). Theoretical analysi...

The Empirical Transfer Function Estimate (ETFE) is the ratio of the Fourier transforms of the output and input signals of a system. It works well when the input signal is deterministic and exactly known. However, when the input signal is random, or it can only be observed with an observation error, the quality of the ETFE deteriorates. Its variance can be infinite even for large signal-to-noise...

Nanoimprinting lithography (NIL) is investigated as a promising method to define nanostructure; however, finding a practical method to achieve large area patterning of conjugated polymer remains a challenge. We demonstrate here that a simple and cost-effective technique is proposed to fabricate the nanoimprinted P3HT nanograting by solvent-assisted room temperature NIL (SART-NIL) method with pa...

We investigated the morphology and swelling behavior of a new graft-type of anion exchange membrane (AEM) containing 2-methylimidazolium groups by using a contrast variation small angle neutron scattering (SANS) technique. These AEMs were prepared by radiation-induced grafting of 2-methyl-1-vinylimidazole and styrene into poly(ethylene-co-tetrafluoroethylene) (ETFE) films and subsequent N-alkyl...

We report a new United Atom Force Field (denoted MSUA) for molecular dynamics simulation of the uoro polymers: Poly(tetra uoroethylene) (PTFE), Poly(vinylidene uoride) (PVDF), and Ethylene-tetra uoroethylene (ETFE). The MSUA was obtained from combining quantum chemistry and experimental results. Using the MSUA and periodic boundary conditions, we carried out molecular dynamics simulations using...

The paper reviews the long span structure with ethylene-tetrafluoroethylene (ETFE) coating. ETFE coating properties and possibilities of its application are considered herein. presents results natural heat engineering tests separate cells in form a foil package enclosing segment size various number layers lighting multilayered coatings. It is shown that high thermal protection illuminating para...

The cost of materials is one of the biggest barriers for wastewater driven microbial fuel cells (MFCs). Many studies use expensive materials with idealistic wastes. Realistically the choice of an ion selective membrane or nonspecific separators must be made in the context of the cost and performance of materials available. Fourteen membranes and separators were characterized for durability, oxy...

Mechanical strength testing of ethylene-tetrafluoroethylene (ETFE) film is performed on the test machine INSTRON. The average elastic modulus 35.8 MPa. Under subsequent loading, elastic-to-plastic stage transition occurs with decreasing to 1.78–2.71 MPa and then 0.06–0.086 Strength ETFE 250 µm thick at 8.577 kPa uniformly distributed load does not lead rupture either positive (15–18 °С) or nega...
