(3) The present study investigates the levels of zinc, cadmium and lead in four brown algae, three red algae and four green algal species collected from Aqaba.
(4) The influence of pH, algal concentration, and algal growth phase on the requisite cationic flocculant dose is also reported.
(5) A method is described for the first time for rapid and accurate discrimination among several algal types by their light-scattering properties alone.
(6) Assays of radiolabeled BaP metabolism in Selenastrum showed that the majority of radioactivity associated with BaP was found in media as opposed to algal cell pellets, that the extent of metabolism was BaP concentration dependent, and that the proportion of various metabolites detected was a function of the light source.
(7) The main cause for such algal blooms is an overload of phosphorus, which washes into lakes from commercial fertiliser used by farming operations as well as urban water-treatment centres.
(8) The electron paramagnetic resonance spectrum of the reduced form shows much similarity to plant and algal ferredoxins with gx = 1.90, gy = 1.97 and gz = 2.07.
(9) These tetrapyrrole groups on the algal proteins are shown to provide them with the potential of ating as efficient electron donors and acceptors.
(10) The clinical features of the 'Palm Island mystery disease' cannot be explained on the basis of toxocariasis, nor do they correlate with the known manifestations of algal toxicity.
(11) Harmful algal blooms fuelled by water pollution are getting so large that they are visible from space.
(12) Under the experimental conditions, chemically induced algal flocculation occurred with the addition of cationic polyelectrolyte, but not with anionic or nonionic polymers, although attachment of all polyelectrolyte species to the algal surface is shown.
(13) Male weanling rats were fed on a retinol-deficient diet for 60 d. Thereafter, the rats were divided into groups and fed on a diet deficient in retinol or supplemented with retinol, synthetic beta-carotene, dry alga or an algal oil-extract.
(14) The DNA-containing nucleomorph of cryptomonad algae appears to be the vestigial nucleus of such an algal endosymbiont.
(15) The results signify that the mechanism of charge separation and water oxidation involved in all three orgainsms is the same, but that the pool of secondary electron acceptors between Photosystem II and Photosystem I is more reduced in the dark, in the algal cells, than in the isolated spinach chloroplasts.
(16) Modification of histidine residues by diethyl pyrocarbonate inactivated vertebrate and algal prolyl 4-hydroxylase and vertebrate lysyl hydroxylase, indicating that histidine residues function in the catalytic site of these 2-oxoglutarate-coupled dioxygenases.
(17) In the presence of Na(+) at 5 mM and K(+) at 350 mM, the ATPase is completely inhibited by p-chloromercuric benzoic acid 10(-4) M, N-ethyl maleimide 10(-3) M, and iodoacetamide 10(-2) M, but is insensitive to ouabain at 10(-7) to 10(-3) M. This study demonstrates for the first time that algal plasma membrane contains an ATPase that is synergistically stimulated by Na(+) and K(+).
(18) Previous work suggested that the tufA gene, encoding protein synthesis elongation factor Tu, was transferred from the chloroplast to the nucleus within the green algal lineage giving rise to land plants.
(19) This indicates that the algal-bacterial cenosis within a biological life-support system has signs of a self-regulating system.
(20) spectra from both the non-deuterated and the fully deuterated algal DNA sample.

(n.) Alt. of Argali
Example Sentences:
(1) Pyr-Lys-Leu-Argal dibutylacetal, a precursor of this immobilized ligand, was synthesized by a fragment condensation procedure, in which one of the thermolysin-digestion products of leupeptin dibutylacetal, H-Leu-Argal dibutylacetal, was used as a key intermediate.
(2) Pyroglutamyl-lysyl-leucyl-argininal (Pyr-Lys-Leu-Argal) immobilized on gel matrix through the epsilon-amino group of its lysine residue was shown to be an efficient biospecific affinity adsorbent for purification of urokinase.
(3) A gel containing D-Phe-D-Phe-Argal (an aldehyde derivative of arginine) was very effective in purifying tPA derived from cell culture media at small scale (milligrams) and at large (multi-grams).
