Resistance for Genotoxic Damage in Mesenchymal Stromal Cells Is Increased by Hypoxia but Not Generally Dependent on p53-Regulated Cell Cycle Arrest. [PDF]

open access: yesPLoS ONE, 2017
Adult stem cells including multipotent mesenchymal stromal cells (MSC) acquire a high amount of DNA-damage due to their prolonged lifespan. MSC may exert specific mechanisms of resistance to avoid loss of functional activity.

Principal component analysis and perturbation theory–based robust damage detection of multifunctional aircraft structure [PDF]

open access: yes, 2013
A fundamental problem in structural damage detection is to define an efficient feature to calculate a damage index. Furthermore, due to perturbations from various sources, we also need to define a rigorous threshold whose overtaking indicates the ...

Research progress on the characterization of irradiation damage defects and performance control of titanium alloy

open access: yesJournal of Aeronautical Materials, 2022
Under the high-energy particle impingement and cascade effect, different types of radiation damage defects occur in metals. The aggregation and evolution of radiation damage defects can lead to the destruction of the internal structural stability and the

Developing methods for testing the resistance of white cabbage against Thrips tabaci [PDF]

open access: yes, 2001
Since the damage of the onion thrips (Thrips tabaci Lindemann) first occurred on white cabbage in Hungary several observations have been carried out, both in Hungary and abroad, to assess varietal resistance.

The causes of holes and loss of physical integrity in long‐lasting insecticidal nets

open access: yesMalaria Journal, 2021
Background Long-lasting insecticidal nets (LLINs) are expected to last for at least 3 years, but whilst this may be achieved from an insecticidal perspective, physical protection is frequently compromised much earlier because of the rapid accumulation of

Mapping genes for resistance to sprouting damage in wheat

open access: yes, 2002
A series of experiments to investigate the genetic basis of pre-harvest sprouting are reported. The results are combined with previously published studies in a composite genetic map for sprout resistance in hexaploid wheat.

Uni- and multivariate approaches to evaluating the susceptibility of wheat hybrids to Fusarium head blight

open access: yesCzech Journal of Genetics and Plant Breeding, 2016
Fusarium head blight (FHB) is a disease of small grain cereals caused by Fusarium species. The pathogens affect spikes and kernels, resulting in reductions of yield and its quality.

Evaluation of Using Natural Fillers to Improve Moisture Damage Resistance and the Use of Pull-Off Tensile Test in Determining Moisture Damage Resistance in Asphalt Mixture

open access: yesApplied Sciences, 2020
Moisture is one of the critical failures affecting asphalt pavement. It has been recently found that moisture created by rainwater and undrained water deteriorate the bonding interface between asphalt mastic and aggregate. Using different mineral fillers
