What's the difference between bleaching and blenching?
Bleaching
Definition:
(p. pr. & vb. n.) of Bleach
(n.) The act or process of whitening, by removing color or stains; esp. the process of whitening fabrics by chemical agents.
Example Sentences:
(1) The transient was characterized by bleaching in the 550-585-nm regions within 6 ps and recovery in approximately 20 ps.
(2) All recombinants were found to be photochemically active, in that optical bleaching produced a temperature- and lipid chain-length-dependent mixture of species absorbing at 480 and 380 nm.
(3) Lesions in either the ventral subiculum or the anterolateral part of the amygdalohippocampal area caused bleaching in the ventromedial hypothalamic nucleus.
(4) All are satisfied by [Formula: see text], where N is the size of rod signal, constant for threshold; theta, theta(D) are steady backgrounds of light and receptor noise; varphi is the threshold flash with sigma a constant of about 2.5 log td sec; B the fraction of pigment in the bleached state.
(5) A simple method for distinction between RNA- and DNA-containing structures in aldehyde- and osmiumtextroxide-fixed electron microscopic autoradiographs (or ordinary thin sections) is described: the developer and the acetic acid used for processing autoradiographs extract selectively uranium acetate from DNA containing-structures which, after staining with lead citrate, leads to a characteristically 'bleached' appearance of the DNA.
(6) Sulphite bleached the flavin of cellobiose oxidase, but gave no reaction with the 31 kDa haem protein, suggesting an absence of flavin.
(7) A new, terrible curse that comes on top of the bleaching, the battering, the poisoning and the pollution.
(8) We have tried to discover whether bleaching raises the threshold by desensitizing the rods, or (like backgrounds) by attenuating their signals.
(9) Additionally, reconstitution of a distinct absorption band, centered around 540 nm, was achieved by addition of exogenous 9-cis-retinal to bleached, isolated eyespot apparatuses.
(10) But the Guardian can now reveal Australia will also need to report on how it is dealing with the current bleaching, where almost a quarter of the coral on the reef has been killed.
(11) Measurements were made of the time course and amplitude of the change in real part of admittance, DeltaG, of a suspension of frog rod outer segments, following a flash of light bleaching about 1% of the rhodopsin content of the rods.
(12) Concentration gradients of metarhodopsin along the lengths of microvilli were produced by local bleaches, accomplished by irradiation with small spots of orange light at pH 9 in the presence of glutaraldehyde or formaldehyde.
(13) Bleaching a few per cent of the rhodopsin molecules of a rod suspension induces a 60% decrease achieved in less than 12 sec.
(14) Consequently, the rate of the bleaching is strongly dependent on the permeability of the thylakoid to the available anion.
(15) Incidentally, it’s the algae that give the coral its colour; and so when it’s ejected, the coral takes on a ghostly white hue, giving rise to the term “bleaching”.
(16) A suggested method for internal bleaching and restoring the access cavity is presented.
(17) Rod outer segment membranes and reassociated stripped disc membrane samples containing divalent cations showed similar phosphodiesterase activities in response to low fractional rhodopsin bleaches (e.g.
(18) Facebook Twitter Pinterest Coral bleaching on the Great Barrier Reef worse than for decades The photos were taken from around Lizard Island by Lyle Vale from Coral Watch at the University of Queensland .
(19) The permethylated rhodopsin thus formed is active toward bleaching, regeneration with 11-cis-retinal, and the activation of the GTPase (G protein) when photolyzed.
(20) When the acyl-CoA dehydrogenases were reacted with moderate excesses of acyl-CoA substrates in D2O in the absence of an electron acceptor, maximum bleaching of the FAD absorbance and the appearance of the long wavelength absorbance, attributed to a charge transfer complex, were observed.
Blenching
Definition:
(p. pr. & vb. n.) of Blench
Example Sentences:
(1) Four peptides were synthesized that correspond to relatively hydrophilic segments of the human HepG2 glucose transporter (Mueckler, M., Caruso, C., Baldwin, S.A., Panico, M., Blench, I., Morris, H.R., Allard, W. J., Lienhard, G.E., and Lodish, H.F. (1985) Science 229, 941-945), including a C-terminal segment.
(2) The word still makes me blench – Orangemen marching, Gazza playing an imaginary flute to Rangers fans, sectarian hatreds.
(3) Antibodies were raised against synthetic peptides corresponding to most of the regions of the human erythrocyte glucose transporter predicted to be extramembranous in the model of Mueckler, Caruso, Baldwin, Panico, Blench, Morris, Lienhard, Allard & Lodish [(1985) Science 229, 941-945].
(4) That's why no one blenched when Hollande said in 2006: "I don't like the rich.
(5) Western blots of whole membrane extracts revealed that the polyclonal antibody to band 4.5 used to isolate cDNA clones presumed to code for the transporter (Mueckler, M., Caruso, C., Baldwin, C.A., Pancio, M., Blench, J., Morris, H.B., Allard, W.J., Lienhard, G.E.
