Paléontologue de renommée internationale, Yves Coppens est spécialisé en paléontologie humaine et professeur au Collège de France. Il est notamment co-auteur en 1974 de la découverte de Lucy, Australopthecus afarensis, ayant vécue, il y a plus de trois millions d'années sur le sol africain. Il a publié entre autres ouvrages : "Le singe, l'Afrique et l'homme" en 1983, et "Pré-ambules" en 1988. (source : Média-Scérén)Durée : 00:56:47Thème : Préhistoir
Relativistic analytical wave functions and scattering factors for neutral atoms beyond Kr and for all chemically important ions up to I-
No full textRelativistic wave functions for elements with Z = 37-54 [Su & Coppens (1998). Acta Cryst. A54, 646-652] have been fitted with a linear combination of Slatertype functions as defined by Bunge, Barrientos & Bunge [At. Data Nucl. Data Tables (1993), 53, 113-162], for use in charge-density analysis and other applications. In addition, numerical relativistic wave functions have been calculated for all chemically relevant ions up to Z = 54, and corresponding analytical expressions have been derived. X-ray scattering factors calculated from the numerical wave functions are parameterized [in the sin(θ)/lambda; ranges 0.0-2.0, 2.0-4.0 and 4.0-6.0 Å-1] with six Gaussian functions, using the same method applied previously by Su & Coppens

Le marchand de fables est repassé
No full textIs that "The fable vendor is back"? Bruno Coppens solicited remakes of La Fontaine's FC and got these responses. There seem to be about a dozen poetic responses and about five cartoon presentations. As the back cover points out, some are, by turns, exotic, anti-academic, politically incorrect, romantic, cynical, erudite. There is a bit of everything here: poetry, prose, drama, individual cartoons, cartoon panels, painting. Coppens himself has two submissions. One is titled "Le corps beau et l'heureux noir." Go ahead and say it! It has an appropriate accompanying photograph of a painting or drawing. Another favorite cartoon -- perhaps from Coppens again? -- makes the letters of the FC title into the scene itself (51). I suspect that several of these pieces have a certain amount of "Abruxellation," that is, "Brusselizing" of their terminology. I delight to see people enjoying fables this way. Even I can make delightful sense out of Coppens' verse letter sent to his invited collaborators in the "Préfable" (5-7). Good fun!Language note: FrenchBruno Coppens et a
USPOREDNO ISTRAŽIVANJE GONADOSOMATSKOG INDEKSA (GSI) I MORFOLOGIJE GONADA AFRIČKOG SOMA (Clarias gariepinus) HRANJENOG UNICAL AQUA HRANOM I KOMERCIJALNOM HRANOM PROIZVOĐAČA COPPENS
No full textA comparative study of the gonado-somatic index (GSI) and gonad gross morphology of African catfish, Clarias gariepinus fed Unical Aqua feed and Coppens commercial feed was carried out for six months in concrete tanks. Two triplicate groups of 50 postfingerlings with a mean bulk weight of 0.50 ± 0.02 kg were stocked in circular concrete tanks, area 16.63 m2 labeled A1, A2, A3, B1, B2 and B3. Fish in units A1, A2 and A3 were fed Coppens feed while fish in units B1, B2 and B3 were fed Unical Aqua feed twice daily at 3% of their body weights. Results obtained showed that mean gonad weight (99.03 ± 16.57 g) and the GSI (15.89 ± 2.10%) of female C. gariepinus fed Unical Aqua feed was not significantly different (P>0.05) from fish fed Coppens feed with mean gonad weight (91.80 ± 12.83 g) and the GSI (13.81 ± 2.49%). In male fish fed Unical Aqua feed, mean gonad weight (7.08 ± 1.17 g) and the GSI (1.16 ± 0.30%) were not significantly different (P>0.05) from male fish fed Coppens feed with mean gonad weight (6.77 ± 1.09 g) and the GSI (1.12 ± 0.32%). In female fish fed both feeds, there was a positive significant relationship between the GSI and total length, total weight and gonad weight. In male fish fed both feeds, there was also a positive non-significant (P>0.05) relationship between the GSI and total length, total weight and gonad. Food conversion efficiency (FCE) was insignificantly higher (P>0.05) in fish fed Coppens feed (50.94 ± 0.91%) than fish fed Unical Aqua feed (50.37 ± 1.29 %). Histology of ovaries and testes of fish fed the two experimental diets showed normal development and distribution of oocytes and interstitial cells. Proximate analysis of the dry matter showed that moisture content, fat content, crude fibre content, ash content, carbohydrate and caloric value (C/V) differed significantly among experimental groups (P0.05). Physicochemical parameters were within acceptable range for fresh water fish culture. Based on these findings, Unical Aqua feed competed favorably with Coppens feed in terms of the GSI and gross gonad morphology of C. gariepinus and, on the basis of affordability, Unical Aqua feed is more economical and therefore recommended for fish farmers.Usporedno istraživanje gonadosomatskog indeksa (GSI) i morfologije gonada afričkog soma, Clarias gariepinus, hranjenog Unical Aqua hranom i komercijalnom hranom proizvođača Coppens (za životinje) provedeno je tijekom šest mjeseci u betonskim spremnicima. Dvije trostruke skupine od 50 jedinki mlađi prosječne težine 0,50 ± 0,02 kg pohranjene su u kružnim betonskim spremnicima površine 16,63 m2, s oznakama A1 , A2 , A3 , B1 , B2 i B3. Riba u jedinicama A1, A2 i A3 hranjena je hranom proizvođača Coppens, a riba u jedinicama B1, B2 i B3 hranjena je Unical Aqua hranom dvaput dnevno na 3% svoje tjelesne težine. Dobiveni rezultati su pokazali da srednja težina gonada (99,03 ± 16,57 g) i GSI indeks (15,89 ± 2,10 %) ženke C. gariepinus hranjene Unical Aqua hranom nisu bili značajno različiti (P>0,05) od težine ribe hranjene hranom proizvođača Coppens, čija je srednja težina gonada bila 91,80 ± 12,83 g, a GSI indeks 13,81 ± 2,49%. Kod mužjaka ribe hranjene Unical Aqua hranom, prosječna težina gonada bila je 7,08 ± 1,17 g, a GSI indeks 1,16 ± 0,30%, što se neznatno razlikuje od vrijednosti kod mužjaka ribe hranjene hranom proizvođača Coppens, čija je prosječna težina bila 6,77 ± 1,09 g, a GSI indeks 1,12 ± 0,32%. Kod ženki ribe hranjene i jednom i drugom hranom uočena je pozitivna značajna povezanost između GSI indeksa i ukupne dužine, ukupne težine i težine gonada. Kod mužjaka ribe hranjene i jednom i drugom hranom također je uočena pozitivna, ali neznačajna (P>0,05) povezanost između GSI indeksa i ukupne dužine, ukupne težine i težine gonada. Hranidbena iskoristivost (FCE) neznatno je veća (P>0,05) kod ribe hranjene hranom proizvođača Coppens (50,94 ± 0,91%) u odnosu na ribu hranjenu Unical Aqua hranom (50,37 ± 1,29%). Histologija jajnika i testisa kod ribe podvrgnute dvjema eksperimentalnim dijetama pokazala je normalan razvoj i distribuciju jajnih i intersticijskih stanica. Približna analiza suhe tvari pokazala je značajnu razliku između sadržaja vlage, masti, sadržaja sirovih vlakana, sadržaja pepela, ugljikohidrata i kalorijske vrijednosti (C/V) u eksperimentalnim grupama (P0,05). Fizikalno-kemijski parametri bili su unutar prihvatljivih granica za kulturu slatkovodnih riba. Na temelju ovih nalaza, Unical Aqua hrana i hrana proizvođača Coppens su prilično slične po svom učinku na GSI indeks i morfologiju gonada C. gariepinus, jedino je u smislu dostupnosti Unical Aqua hrana ekonomičnija i stoga se preporučuje uzgajivačima ribe
