Nuclear Reactivity Calculation with Reduction of Fluctuations

open access: yesInternational Journal of Technology, 2023
This article presents a study based on a series of numerical experiments. It demonstrates the possibility of reducing fluctuations in the calculation of reactivity using the second Bernoulli number based on the approximation of the Euler-Maclaurin ...

Reactive Arthritis [PDF]

open access: yesInternational Journal of STD & AIDS, 1994
Reactive arthritis (ReA) develops after an infection elsewhere in the body, generally in the genitourinary or intestinal tract. Chlamydia trachomatis, Yersinia enterocolitica, salmonella, shigella, and campylobacter are frequent triggering agents. Between 60% and 90% of patients are positive for HLA-B27.

Alpha-Glucosidase- and Lipase-Inhibitory Phenalenones from a New Species of Pseudolophiostoma Originating from Thailand

open access: yesMolecules, 2020
The alpha-glucosidase- and lipase-inhibitory activities of three phenalenones (1−3) and one phenylpropanoid (4) from the ethyl acetate extracts of a Pseudolophiosptoma sp. are described.

Quantitative structure–reactivity relationships for synthesis planning: The benzhydrylium case [PDF]

open access: yes, 2023
Selective and feasible reactions are top targets in synthesis planning, both of which depend on the reactivity of the molecules involved. Mayr’s approach to quantifying reactivity has greatly facilitated the planning process, but reactivity parameters ...

Reactivity and reactions to regulatory transparency in medicine, psychotherapy and counselling [PDF]

open access: yes, 2012
We explore how doctors, psychotherapists and counsellors in the UK react to regulatory transparency, drawing on qualitative research involving 51 semi-structured interviews conducted during 2008–10. We use the concept of ‘reactivity mechanisms’ (Espeland

Controlling the dispersion of supported polyoxometalate heterogeneous catalysts: impact of hybridization and the role of hydrophilicity–hydrophobicity balance and supramolecularity

open access: yesBeilstein Journal of Nanotechnology, 2014
The hybridization of polyoxometalates (POMs) through an organic–inorganic association offers several processing advantages in the design of heterogeneous catalysts.
