Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Chlorhexidine Resistance or Cross-Resistance, That Is the Question

Antibiotics, 2023
Chlorohexidine (CHX) is a widely used biocide in clinical and household settings. Studies over the last few decades have reported CHX resistance in different bacterial species, but at concentrations well below those used in the clinical setting. Synthesis of these findings is hampered by the inconsistent compliance with standard laboratory procedures ...

CROSS-RESISTANCE TO CARDIOTOXIC AGENTS

Canadian Journal of Biochemistry and Physiology, 1961
Experiments on rats indicate that, following pretreatment with fluorocortisol and Na-acetate, various stressors (restraint, muscular exercise, cold baths, noradrenaline) produce extensive cardiac necroses and high mortality. Gradual adaptation by pretreatment with restraint, muscular exercise, cold baths, or noradrenaline protects against this cardiac-

Cross-Resistance Studies with Neomycin Antibiotics

Nature, 1962
RECENT disclosures of structures of the components of neomycin complex1 and of structurally related antibiotics2–4 provide opportunities for studying biological activities in relation to molecular structure. Cross-resistance and antibiotic-requiring responses may help toward a better understanding of the biological activities.

Biorational insecticides: Mechanism and cross-resistance

Archives of Insect Biochemistry and Physiology, 2005
AbstractPotency and cross‐resistance of various biorational insecticides, exemplified by the whitefly Bemisia tabaci, have been studied. Bemisia tabaci were exposed to the juvenile hormone mimic pyriproxyfen for the past 12 years resulting in an over 2,000‐fold resistance, but there was no appreciable cross‐resistance with the benzoylphenyl urea ...

In vitro detection of cross-resistant and non-cross-resistant agents with fluorouracil for patients with colorectal cancer

International Journal of Clinical Oncology, 2005
Fluorouracil-based chemotherapy, such as that with 5-fluorouracil (5-FU)/leucovorin, is standard as first-line chemotherapy for advanced colorectal cancer (CRC) in Japan. However, the best agent for second-line chemotherapy after fluorouracil failure is yet to be determined.

Herbicide cross resistance in weeds

Crop Protection, 2012
Abstract With no major new site-of-action herbicide introduced into the marketplace in the last 20 years, the stagnation or decline in available herbicides in the past decade in a number of jurisdictions, and ever-increasing incidence of herbicide-resistant (HR) weeds, more efficient use of our existing herbicide tools will be required to proactively

Cross-resistance to alkylating agents in multiple myeloma

Cancer, 1983
In order to ascertain whether multiple myeloma patients resistant to one alkylating agent would respond to a second one, high-dose intermittent cyclophosphamide was administered to 12 patients showing resistance to melphalan and prednisone. On the other hand, intermittent melphalan and prednisone treatment was employed in eight myeloma patients ...
