Chawla-Numerov method revisited
(1991-08-27)
The well-known two-step fourth-order Numerov method was shown to have better interval of periodicity when made explicit, see Chawla (1984). It is readily verifiable that the improved method still has phase-lag of order 4. ...

Modulation of frequency preference in heterogeneous populations of theta-resonant neurons
(Pergamon-Elsevier, 2020)
Neurons from several brain regions resonate in the theta frequency range (4-12 Hz), displaying a higher voltage response to oscillatory currents at a preferred 'resonant' frequency (f(R)). Subthreshold resonance could ...
Effect of gramine on the susceptibility of barley leaves to Pseudomonas syringae
(1990)
The effects of gramine on the bacterium Pseudomonas syringae in culture and on barley leaf disks were studied. Gramine prolonged the lag phase of growth and decreased the size of the population at stationary phase at ...
Microcin E492 Amyloid Formation Is Retarded by Posttranslational Modification
(American Society for Microbiology, 2013)
Microcin E492, a channel-forming bacteriocin with the ability to form amyloid fibers, is exported as a mixture of two forms: unmodified
(inactive) and posttranslationally modified at the C terminus with a salmochelin-like ...
Impacto da aflatoxina B1, montmorilonita e β-glucana na fermentação ruminal in vitro
(Universidade Federal de Santa MariaBRZootecniaUFSMPrograma de Pós-Graduação em Zootecnia, 2015-02-27)
The effects of aflatoxin B1 (AFB1) (1μg/mL) were evaluated and sorbents β-glucans derived from Saccharomyces cerevisae with 65% of active ingredient (β-glu) (1mg/mL) and montmirillonite (MMT) (5mg/mL) under ruminal ...
The Antarctic yeast Candida sake: Understanding cold metabolism impact on wine
(Elsevier B.V., 2017)
© 2017 Elsevier B.V. Current winemaking trends include low-temperature fermentations and using non-Saccharomyces yeasts as the most promising tools to produce lower alcohol and increased aromatic complexity wines. Here we ...
Basilar membrane mechanics at the base of the chinchilla cochlea. II. Responses to low-frequency tones and relationship to microphonics and spike initiation in the VIII Nervea)
(1986)
Low-frequency stimuli (40-to 1000-Hz tones) have been used to correlate the motion of the 8-to 9-kHz place of the chinchilla basilar membrane with the cochlear microphonics recorded at the round window and with the responses ...
The effect of temperature on microbial growth in apple cubes packed in film and preserved by use of orange juice
(Wiley Blackwell Publishing, Inc, 2004-11)
Red delicious apple cubes were packed in fresh orange juice containing chemical preservatives (citric and ascorbic acid, potassium sorbate) and covered with plastic films of different gas permeabilities (polyethylene and ...
