Construction Trade Work Is Associated With Accelerated Decline in Kidney Function

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Construction workers are exposed to airborne particulates, organic solvents, and metals—agents linked to elevated risk of chronic kidney disease (CKD). Few studies have evaluated whether construction trade work is associated with longitudinal changes in estimated glomerular filtration rate (eGFR), a key indicator of kidney function.

The Pozzolanic reaction of silica fume

, 2012
Silica fume is a very important supplementary cementitious binder in High-Performance and Ultra High-Performance Concretes. Through its pozzolanic reaction the silica fume densifies the concrete micro-structure, in particular it strengthens the paste ...

pH‐Responsive Ultrasmall Iron Oxide Nanoassemblies for Activatable T2/T1 Magnetic Resonance Imaging

Advanced NanoBiomed Research, EarlyView.
This research reports a pH‐responsive ultrasmall iron oxide nanoparticle (USIONs)/polymer nanoassemblies for activatable magnetic resonance imaging. Amphiphilic diphosphonic acid block copolymers compactly encapsulate USIONs to generate T2‐weighted contrast at physiological pH, while acidic conditions trigger disassembly, activating T1‐weighted ...

A STUDY ON THE CHARACTERIZATION OF SILICA FUME AND THE EVALUATION OF PROPERTIES OF CONCRETE CONTAINING SILICA FUME

Doboku Gakkai Ronbunshu, 1995
コンクリートにシリカフュームを用いることにより, コンクリートの高強度化などの効果が期待されている. しかしながら, シリカフュームそのものの品質特性や, コンクリートの諸特性に影響を及ぼすシリカフュームの品質についても未だに不明確であり, シリカフュームに関する規格, 基準も整備されていないのが現状である. このような背景から, 本研究ではまず, 我が国で入手可能な13銘柄のシリカフュームを対象とし, その品質特性を明らかにし, 次にコンクリートの諸特性に影響を及ぼすシリカフュームの品質指標を明らかにすることを試み, これを通じてシリカフュームの品質とその評価に関する提案を行ったものである.

Pan‐Frying Conditions Affect the Tocopherol Intake From Edible Oils: Results From Temperature Measurements and the Standardized Heating of an Edible Oil

Journal of the American Oil Chemists' Society, EarlyView.
High temperatures in a short time on electric stoves in private homes. Fast loss of tocochromanols using standardized conditions and a miniature heating apparatus. ABSTRACT Tocochromanols (vitamin E compounds) are essential ingredients in human nutrition. Their consumption via edible oils is considered the main source of dietary intake.

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

Fine Particulate Matter Constituents, Ozone, and Systemic Lupus Erythematosus: A Large General‐Population Cohort Analysis With Extended Quantile g‐Computation

Arthritis &Rheumatology, EarlyView.
Objective The aim of this study was to investigate whether exposure to mixture of individual fine particulate matter (PM2.5) chemical constituents is associated with incident systemic lupus erythematosus (SLE) and if ozone modifies this association and/or is associated with SLE onset.

Substrate stiffness regulates cell fate and its applications in the repair of motor system: From two dimensions to three dimensions

BMEMat, EarlyView.
Substrate stiffness with different dimensions (2D and 3D) exerts a regulatory role in cellular behaviors, thereby governing cell fate decisions. Biomaterials with tunable stiffness exhibit substantial functional potential for the repair and regeneration of the motor system.
