The crystallinity degree influence on the weather resistance of CF/PPS composites
Polyphenylene sulphide (PPS) is a semi-crystalline high-performance thermoplastic used in the aeronautic field as a composite usually reinforced with carbon fibers. The crystallinity of semi-crystalline thermoplastics can ...
Tetraciclinas: un modelo de resistencia antimicrobiana
(Universidad de Chile, Facultad de Ciencias Veterinarias y Pecuarias, 2007-12)
Tetracyclines are a group of broad-spectrum antibiotics whose general usefulness has been reduced with the onset of bacterial resistance. Tetracycline resistance is the most frequent bacterial antibiotic resistance ...
Resistance gene analogs and STS markers colocalized with a major QTL conferring resistance to SCMV in tropical maize.
(In: INTERNATIONAL CONGRESS OF PLANT MOLECULAR BIOLOGY, 11., 2015, Iguassu Falls. Abstracts. [S.l.]: International Society for Plant Molecular Biology, 2015. p. 221., 2015)
Water-stress-induced thermotolerance of photosynthesis in bean (Phaseolus vulgaris L.) plants: The possible involvement of lipid composition and xanthophyll cycle pigments
A common feature in plants that are exposed to gradual stressful environmental factors is the development of a level of resistance to such constraints, which sometimes protects against different stressful environmental ...
Effects of specimen geometry and mode loading on crack growth resistance curves of X80 pipeline girth welds
(The Chinese Society of Theoretical and Applied MechanicsBeijing, 2013-06-16)
This work presents an investigation of the ductile tearing properties for a girth weld made of an API 5L X80 pipeline steel using experimentally measured crack growth resistance curves. Use of these materials is motivated ...
Spraying of oxytetracycline and gentamicin onto field-grown coriander did not affect the abundance of resistant bacteria, resistance genes, and broad host range plasmids detected in tropical soil bacteria
Horticultural supplements containing oxytetracycline and gentamicin, two clinically relevant biocides, are widely marketed to prevent or control infections by bacterial phytopathogens. Despite their regular consumption in ...
Inheritance of evolved resistance to a novel herbicide (pyroxasulfone)
(Elsevier Ireland, 2014-01)
Agricultural weeds have rapidly adapted to intensive herbicide selection and resistance to herbicides has evolved within ecological timescales. Yet, the genetic basis of broad-spectrum generalist herbicide resistance is ...
Prevalence of rilpivirine resistance in people starting antiretroviral treatment in Argentina
(Int Medical Press Ltd, 2017-02)
Background: Rilpivirine-based regimens are now preferred or alternative first-line regimens according to many HIV treatment guidelines. Recently, a surveillance study conducted in Argentina determined that prevalence of ...
