A new species of caligid copepod (Siphonostomatoida), Anuretes grandis sp. п., parasitic on the painted sweetlips [Diagrammapictum (Thunberg)] in Taiwan is described. The new species is distinguished from its congeners by having: (1) free margin of céphalothorax not covering fourth pediger, (2) large genital complex longer than 2/3 of the cephalic shield, (3) no maxillary whip, (4) leg 3 with 9 setae on the terminal segment of exopod and 8 plumose setae on the terminal segment of endopod, and (5) armature of I,III on leg 4 exopod. Genus Anuretes Heller, 1865 is reviewed and redefined. Based on the new diagnosis three species (A. chelatus Prahha et Pillai, A. fedderni Price and A. parvulus Wilson) were transferred to Pseudanureles, and two species (A.furcatus Capart and A. renalis Ileegaard) were transferred to Lepeophtheirus. In addition, the following three species of caligids were transferred to Anuretes: Lepeophtheirus fallolunulus Lewis, Heniochophilus indicus Pillai, and Lepeophtheirus rotundigenitalis Prabha et Pillai. The latter is renamed Anuretes occullus nom. n. due to the homonym encountered through this transfer. “Anuretes plectorhynchi Yamaguti” reported by Prabha and Pillai (1986) is renamed Anuretes similis sp. n. and Anuretes yamagutii Prabha et Pillai is relegated to the synonym of Anuretes anomalus Pillai. A key to the 18 species of Anuretes is provided.
Energy transfer from resynthesized protochlorophyllide (PChlide) to chlorophyll (Chl) appeared after 5 h irradiation and additional redarkening of etiolated barley leaves. The transfer was more effective after a longer greening. Benzyladenine (BA) removed delay at the onset of the energy transfer and this process was effective even at very low Chl contents. BA enhanced Chl accumulation more strongly than the development of photosystems. The balance between the rate of Chl synthesis and that of its efflux from PChlide-containing site may determine the number of Chl molecules near PChlide, and thereby the probability of the energy transfer. At a high rate of Chl synthesis a part of its molecules remained near the PChlide synthesis site. Under various conditions of irradiation the slower rate of Chl accumulation corresponded to the more efficient energy transfer. Chl accumulation at PChlide forming site probably Controls the activity of the multienzyme systém of Chl biosynthesis by a feedback mechanism. The BA addition increased the number of EF-mtramembrane particles and the munber of enzyme systems of Chl biosynthesis to the same extent.
Studie zkoumá Whiteheadovo pojetí rozumu (artikulované zejména v jeho knize Funkce Rozumu) jako regulativního faktoru v každém estetickém prožitku, spolu s Whiteheadovým názorem na základní estetickou povahu každého prožitku, každé zkušenosti. Tyto myšlenky jsou srovnávány se současnými nálezy neuroestetiky a recepční estetiky s cílem doložit stimulující povahu Whiteheadovy
filosofie i pro současnou estetiku., Th e study considers Whitehead’s conception of the Reason (articulated especially in his The Function of Reason) as a regulative factor in every aesthetic experience along with Whitehead’s opinion of the basic aesthetic character of every experience. Th ese thoughts are compared with contemporary fi ndings of neuroaesthetics and the Reception aesthetics, in order to demonstrate how stimulating Whitehead’s philosophy is even for the present-day aesthetics., and Vlastimil Zuska.
In this note we consider a linear-fractionai programming problem with equality linear constraints. Following Rohn, we define a generalized relative sensitivity coefficient measuring the sensitivity of the optimal value for a linear program and a linear-fractional minimization problem with respect to the perturbations in the problem data. By using an extension of Rohn's result for the linear programming case, we obtain, via Charnes-Cooper variable change, the relative sensitivity coefficient for the linear-fractional problem. This coefficient involves only the measure of data perturbation, the optimal solution for the initial linear-fractional problem and the optimal solution of the dual problem of linear programming equivalent to the initial fractional problem.
The contents of chlorophyll (Chl) and carotenoids (Car) per fresh mass were lower in shade needles than in sun needles. Ribulose-1,5-bisphosphate carboxylase (RuBPC) activity and contents of soluble proteins were also significantly lower in shade needles. In isolated thylakoids, a marked lower rate of whole chain and photosystem (PS) 2 activities were observed in shade needles. Smaller lower rate of PS1 activity was also observed in shade needles. The artificial exogenous electron donors, diphenyl carbazide (DPC) and NH2OH, significantly restored the loss of PS2 activity in shade needles. Similar results were obtained when Fv/Fm was evaluated by Chl fluorescence measurements. The marked lower rate of PS2 activity in shade needles was due to the lower contents of 47, 33, 28-25, 23, and 17 kDa polypeptides. This conclusion was confirmed by immunological studies showing that the content of the 33 kDa protein of the watersplitting complex was diminished significantly in shade needles. and M. Bertamini, K.
