Ultrafast (UF) NMR spectroscopy is an approach that yields 2D spectra in a single scan. This methodology has become a powerful analytical tool that is used in a large array of applications. However, UF NMR spectroscopy still suffers from an intrinsic low sensitivity, and from the need to compromise between sensitivity, spectral width, and resolution. In particular, the modulation of signal inte...

Fast-growing poplar wood was modified with low molecular weight ureaformaldehyde resin (UF) at 41.5% concentration or phenol-formaldehyde (PF) at concentrations of 15, 25, and 40%. The physical and mechanical properties were measured, and creep behavior tests were carried out under ambient indoor conditions. The specimens were subjected to 30 and 50% of their maximum bending load. The density, ...

[1] Time‐dependent buoyant plumes form at the outflow of tidally dominated estuaries. When estuary discharge velocity exceeds plume internal wave speed c, a sharp front forms at the plume’s leading edge that expands from the time‐dependent source. Using observations of the Columbia River tidal plume from multiple tidal cycles we characterize time‐evolving plume structure and quantify front spee...

The present study investigates major organic foulants in ultrafiltration (UF) of treated domestic wastewater and their removal in slow sand filtration. Identification and quantification of major foulants was conducted in labscale experiments. Quantified results suggest that biopolymers (large molecular protein-like and polysaccharidelike materials) are major organic foulants in UF. This conclus...

Background A novel technology has been developed for ultrafast (UF) singlephoton emission computed tomography (SPECT) myocardial perfusion imaging by employing a pin-hole collimation design and multiple cadmium zinc telluride crystal arrays. The purpose of this study was to compare myocardial perfusion imaging obtained by UF-SPECT with standard (S) SPECT in patients with known or suspected coro...

BACKGROUND The prevalence of heart failure (HF) is increasing rapidly with high readmission rates, mainly due to fluid retention. Ultrafiltration (UF) is a mechanical method for removing fluids. Since UF was introduced only recently in Israel, the skill and experience required for outpatient congested HF patients is scarce. OBJECTIVEs: To evaluate the feasibility and safety of UF therapy in con...

A deeper understanding of the mechanical behavior of ultra-fine (UF) and nanocrystalline (NC) grained metals is necessary with the growing interest in using UF and NC grained metals for structural applications. The cyclic deformation response and behavior of UF and NC grained metals is one aspect that has been gaining momentum as a major research topic for the past ten years. Severe Plastic Def...

A procedure has been reported (1) for the reproducible separation of the total nondialyzable solids (TNDS) of normal human urine into three primary fractions. The most abundant of the-three fractions, designated UF-O, was separated from the other two by virtue of its passage through a collodion ultrafilter membrane. The overall chemical composition of fraction UF-O was described , but no furthe...

BACKGROUND Higher ultrafiltration (UF) rates and extracellular hypo- and hypervolemia are associated with adverse outcomes among maintenance hemodialysis patients. The Centers for Medicare and Medicaid Services recently considered UF rate and target weight achievement measures for ESRD Quality Incentive Program inclusion. The dual measures were intended to promote balance between too aggressive...

Dried milk protein concentrate is produced from skim milk using a combination of processes such as ultrafiltration (UF), evaporation or nanofiltration, and spray drying. It is well established that dried milk protein concentrate (MPC) that contains 80% (MPC80) and greater protein content (relative to dry matter) can lose solubility during storage as a result of protein-protein interactions and ...
