Is there a causal association between genotoxicity and the imposex effect? [PDF]

open access: yes, 2006
There is a growing body of evidence that indicates common environmental pollutants are capable of disrupting reproductive and developmental processes by interfering with the actions of endogenous hormones.

Dextran sulfate enhances the level of an oxidative DNA damage biomarker, 8-oxo-7,8-dihydro-2 0-deoxyguanosine, in rat colonic mucosa [PDF]

open access: yes, 1998
Dextran sodium sulfate (DSS) given in drinking water can induce colonic Inflammation and produce colorectal tumors in rodents, although it is not directly genotoxic.

The DNA damage checkpoint pathway promotes extensive resection and nucleotide synthesis to facilitate homologous recombination repair and genome stability in fission yeast. [PDF]

open access: yes, 2014
DNA double-strand breaks (DSBs) can cause chromosomal rearrangements and extensive loss of heterozygosity (LOH), hallmarks of cancer cells. Yet, how such events are normally suppressed is unclear.

Formation damage effects in a horizontal wells completion [PDF]

open access: yesActa Montanistica Slovaca, 2001
Horizontal well completions are considered to reduce concerns about formation damage because the extra completion interval length in the pay zone offset production lost from reduced permeability around the wellbore.The control of sand flow from ...

Development of engineering design tools to help reduce apple bruising [PDF]

open access: yes, 2007
A large percentage of apples are wasted each year due to damage such as bruising. The apple journey from orchard to supermarket is very complex and apples are subjected to a variety of static and dynamic loads that could result in this damage occurring ...

Preventing sour gas kicks during workover of natural gas wells from deep carbonate reservoirs with anti‐hydrogen sulfide fuzzy‐ball kill fluid

open access: yesEnergy Science & Engineering, 2022
Workover of natural gas wells in deep carbonate gas reservoirs (DCRs) is facing multiple challenges such as fluid leakage, high temperature, and hydrogen sulfide (H2S) gas kick.

Deep learning inter-atomic potential model for accurate irradiation damage simulations

open access: yes, 2019
We propose a hybrid scheme that interpolates smoothly the Ziegler-Biersack-Littmark (ZBL) screened nuclear repulsion potential with a newly developed deep learning potential energy model.

Improvement of device characteristics by multiple step implants or introducing a C gettering layer [PDF]

open access: yes, 1992
Ion implantation is used for realization of the collector in vertical bipolar transistors in a BiCMOS process. Secondary defects, remaining after annealing the implant damage, can give rise to an increased leakage current and to collector-emitter shorts.

Study of barium sulfate dissolution by scale dissolver based on solutions of DTPA

open access: yesAnais da Academia Brasileira de Ciências
In offshore oil wells it is very common to perform seawater injection through injection wells for hydrocarbon recovery. When seawater, rich in sulfate ion, mixes with formation water, whose composition can contain divalent cations such as barium and ...

Local formation of nitrogen-vacancy centers in diamond by swift heavy ions

open access: yes, 2014
We exposed nitrogen-implanted diamonds to beams of swift uranium and gold ions (~1 GeV) and find that these irradiations lead directly to the formation of nitrogen vacancy (NV) centers, without thermal annealing.
