The Conconi Test: Methodology after 12 years of application
No full textThe protocol for the determination of the speed/heart rate relationship during incremental exercise previously described (so-called Conconi test) has been refined and in part modified during 12 years of application. The new protocol calls for time-based increments in exercise intensity that are uniform up to submaximal speeds and progressively greater in the final phase. As in the original article (18), the speed/heart rate relationship is linear at low to moderate speed and curvilinear from submaximal to maximal speeds. A method is presented for the mathematical definition of this relationship, with the calculation of the straightline equation of the linear phase and the identification of the point of transition from the linear to the curvilinear phase (deflection point or heart rate break-point). Analysis of 300 tests selected at random from those in our data base (more than 5000 tests) has enabled us to show that the speed at which the deflection point occurs is significantly lower (p < 0.001) than that at which the acceleration of the final phase begins. This fact demonstrates that the break-point is not brought on by the final acceleration called for in the test protocol. Analysis of the speed/heart rate relationship allows for the determination of the following additional functional indices: l) maximal heart rate (in 21 athletes the maximal heart rate attained in the test and that attained while racing were equal); 2) range of heart beats defining the linear part of the speed/heart rate relationship; 3) range of heart beats from the deflection point to maximal heart rate; and 4) maximal aerobic exercise intensity, obtained through extrapolation of the straight-line equation to maximal heart rate. Data are provided on the conditions of the test subject that modify his speed/heart rate relationship, such as incomplete recovery from previous efforts, inadequate warm-up, or inadequate test procedure with too rapid increments in exercise intensity. Finally, criteria for test acceptability are presented

Memorie antillesi di testimoni forzati: il viaggio per la fede di deportati e galeotti del Re Sole
No full textAll’indomani della Revoca dell’Editto di Nantes, la soluzione della questione protestante prevede anche, per i sudditi ugonotti refrattari alla conversione, l’esperienza delle galere del Re Cristianissimo e la deportazione nei territori d’Oltremare. Le Quatre relations véritables du Sieur Serres (Amsterdam, 1688), così come le altre testimonianze coeve prese in esame, raccontano, senza ovviamente esimersi dal tributo ai topoi del genere, il viaggio di questi « forzati per la fede » dalla Francia alle Antille
1539-1618: tempi, luoghi, protagosti della traduzione di Pietro Aretino in Francia. Con un primo repertorio
No full textI saggio è composto di due sezioni. La prima costituisce un ampliamento degli studi dedicati negli ultimi anni all’analisi delle traduzioni francesi delle opere di argomento religioso di Pietro Aretino, e vuole offrire un quadro completo, relativo all’intera sua produzione.
Si è trattato in primo luogo di ‘fare un po’ d’ordine’ tra i dati trasmessi dalla tradizione riguardo sia ad alcuni ‘fantasmi librari’ – testi di cui troviamo eco in più punti della corrispondenza aretiniana, alla quale si ispireranno i più noti e saccheggiati tra i biografi settecenteschi come il Mazzuchelli ed il Boispréaux, senza che però nessuno mai provi di averne avuto veramente un esemplare tra le mani –, sia ad alcuni testimoni scomparsi – edizioni attestate da cataloghi del passato, di cui non abbiamo trovato traccia nelle biblioteche francesi, ma che potrebbero da un giorno all’altro «resurgir», come scrive Albert L. Labarre, «à l’occasion du catalogage d’un fonds qui ne l’était pas ou au hasard du commerce du livre ancien». Cosa che ha permesso altresì se non di riportare alla luce, almeno di rimettere in giusta luce edizioni per lo più ignorate anche dai più autorevoli specialisti.
Al momento di prendere in esame le diverse traduzioni, particolare attenzione stata accordata alle modalità di circolazione dei testi, cui la critica non ha finora rivolto, a nostro avviso, sufficiente attenzione. Ci riferiamo a quanto è stato fatto prima che il testo facesse il suo ingresso sul mercato – oltre all’opzione per una data forma materiale, certo – allo scopo di influenzare la sua ricezione. Perché è vero che «forms effect meaning», ma non minor peso deve aver avuto la scelta editoriale di pubblicare ad esempio il Dialogue – la traduzione parziale dei Ragionamenti – assieme ad altri testi, e la posizione che si è deciso di attribuirgli all’interno di quell’opera a più voci. Non mero dettaglio a nostro avviso neppure quello della circolazione del libro, del singolo esemplare, oltre che del testo, oltre che della scelta editoriale di pubblicarlo assieme ad altri testi, per il senso che si è voluto o che si è finito per dare ad un’opera legandola per sempre ad un’altra a lei estranea, che molto può contribuire a farci capire, crediamo, della ricezione dell’autore italiano oltralpe.
Sono raccolte nella seconda parte del saggio le descrizioni degli esemplari delle traduzioni francesi delle opere aretiniane da noi ad oggi reperite nelle biblioteche d’Oltralpe. Si tratta, come indica il titolo, di un primo repertorio, poiché è prevista la pubblicazione di un catalogo dei circa 400 esemplari di edizioni italiane e francesi cinque-seicentesche lì conservati

Polyribosomes and control of protein synthesis: effects of sodium fluoride and temperature in reticulocytes
No full textReticulocytes from phenylhydrazine-treated rabbits were pre-incubated with 0·01 M-sodium fluoride to inhibit protein synthesis and dissociate polyribosomes to 80 s ribosomes. Upon incubation of these cells without fluoride, protein synthesis is restored and reaches rates comparable to control cells (not pre-incubated with fluoride) within three minutes at 37°C when only a fraction of the polyribosomes have re-formed. In these cells, polyribosome content and polyribosome size may continue to increase for 60 to 120 minutes at 37°C without a change in rate of protein synthesis. As polyribosome content increases, the specific activity of the polyribosomes remains constant. These data indicate that in these cells polyribosome content is not the factor which limits the rate of protein synthesis. An estimate of the time for globin chain synthesis indicates that it increases progressively as polyribosome content increases. The protein synthesized during polyribosome formation in fluoride pre-incubated cells is predominantly globin and, by sedimentation and chromatographic characteristics, indistinguishable from the protein synthesized in control cells. The effect of the temperature of incubation on protein synthesis by reticulocytes was examined. In contrast to the alterations in polyribosomes with a constant rate of protein synthesis during recovery from the “fluoride effect”, increasing the temperature of incubation of reticulocytes between 17 and 37°C is associated with no change in polyribosome size or content, but an increase in polyribosome specific activity and in rate of protein synthesis. The data are interpreted in terms of mechanisms which might alter polyribosome size, content and/or function in reticulocytes which synthesize no RNA. © 1966, Academic Press Inc. (London) Ltd..

Pengaruh Pemberian Cairan Madu terhadap Titik Defleksi Conconi : Penelitian Eksperimental Laboratorik
No full textThe purpose of the study was to determine the differences between 10% and 5% honey fluid consumption toward Conconi threshold during exercising.
A laboratory experiment using treatments by sub¬ject designs was employed in this study. Subjects of this study were five students of PJKR study program, Faculty of Sport Science, State Univercity of Yogyakarta. The sample is selected by using simple random technique.
The data were mesured by Conconi Threshold of the subjects during exercising and consuming 10% and 5% honey fluid. The modified Conconi test for cyclist is used as the instrument experiment apparatus equipped by heart rate monitor in precision of 97%. The proce¬dure was as follows (1) the subjects ride ergocycle will the speed of 70 rpm/minute (2) their heart rate were monitored at the last 15 seconds of 1 minute duration (3) forty watt is a beginning load to warming up, after exercising as warming up in ten minutes the load is added to 50 watt, and in interval of 1 minute adding by 5 watt.(4) the test was done up until testee were exhausted. The data collected were analysed using anava LSD, and t test in 5% significance.
The results was as follows (1) there are no sig¬nificant differences between aqua and 10% honey fluid consumtion toward on the Conconi threshold (p > ,05). (2) there are no significant differences between aqua and 5% honey fluid consumtion toward on the Conconi threshold (p > .05). (3) there are no significant differences between 10% and 5% honey fluid consumtion toward on the Concord threshold (p > .05). There was a tendency that honey fluid consumption at 10% and 5% up graded the work burden than aqua in the same heart rate, and there was also a tendency that honey fluid consumption of 10% and 5% was lower than the consumption or aqua with the same work burden
