Effect of varied waste concrete ratios on the mechanical properties of polymer concrete

Open Engineering, 2023
Polymer concrete (PC) was developed at the end of the 1950s and gained popularity in the 1970s for precast parts, flimsy floor coverings, and repairs. Due to its superior performance over traditional Portland cement concrete, which offers many benefits ...

Admixture Mapping Reveals Candidate Regions for Methotrexate Neurotoxicity Susceptibility: A Reducing Disparities in Acute Leukemia Consortium Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Neurotoxicity is a rare, often dose‐limiting adverse effect of methotrexate (MTX) therapy that disproportionally affects Latino children. Factors contributing to the observed disparity are not well understood. This study leveraged admixture mapping to identify genetic regions associated with MTX‐related neurotoxicity susceptibility ...

Physical and Mechanical Properties of High Strength Concrete containing PVC Waste as a Sand Replacement

Sulaimani Journal for Engineering Sciences, 2020
In this research, physical and mechanical properties of high strength concrete containing PVC waste have been investigated. The fine aggregate was replaced with PVC waste with two different gradings (fine grading and coarse grading) at dosages of 0%,

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...

Technological characterization and utilization of recycled aggregate in the fine fraction in substitution to the fine natural aggregate for concrete production [PDF]

RECYCLING AND SUSTAINABLE DEVELOPMENT, 2019
Civil Construction and Demolition Waste (CDW), after screening process, can go through benefication process which enables physical alterations obtaining samples with different granulometry. X-ray diffraction tests were performed in order to identify the mineral components present in the samples.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Laboratory study on mechanical properties of self compacting concrete using marble waste and polypropylene fiber

Cleaner Materials, 2022
The marble sector has produced a large amount of waste in recent decades, which is being increased substantially over time. Marble waste is an extremely polluting form of industrial waste, owing to its highly alkaline contentas well as its production and
