sequential injection analysis for automation of the winkler methodology with real time simplex optimization and shipboard application
Analytica Chimica Acta, 2010Co-Authors: Burkhard Horstkotte, Antonio Tovar Sanchez, Carlos M Duarte, Vìctor CerdáAbstract:Abstract A multipurpose analyzer system based on sequential injection analysis (SIA) for the determination of dissolved oxygen (DO) in seawater is presented. Three operation modes were established and successfully applied onboard during a research cruise in the Southern ocean: 1st, in-line execution of the entire Winkler method including precipitation of manganese (II) hydroxide, fixation of DO, precipitate dissolution by confluent acidification, and spectrophotometric quantification of the generated iodine/tri-iodide (I 2 /I 3 − ), 2nd, spectrophotometric quantification of I 2 /I 3 − in samples prepared according the classical Winkler protocol, and 3rd, accurate batch-wise titration of I 2 /I 3 − with thiosulfate using one syringe pump of the analyzer as automatic burette. In the first mode, the zone stacking principle was applied to achieve high dispersion of the reagent solutions in the sample zone. Spectrophotometric detection was done at the isobestic wavelength 466 nm of I 2 /I 3 − . Highly reduced consumption of reagents and sample compared to the classical Winkler protocol, linear response up to 16 mg L −1 DO, and an injection frequency of 30 per hour were achieved. It is noteworthy that for the offline protocol, sample metering and quantification with a potentiometric titrator lasts in general over 5 min without counting sample fixation, incubation, and glassware cleaning. The modified SIMPLEX methodology was used for the simultaneous optimization of four volumetric and two chemical variables. Vertex calculation and consequent application including in-line preparation of one reagent was carried out in real-time using the software Autoanalysis. The analytical system featured high signal stability, robustness, and a repeatability of 3% RSD (1st mode) and 0.8% (2nd mode) during shipboard application.

Training Analysis of a 100m Hurdles Runner in the Years 2004 - 2007
2008Co-Authors: Seidlová PetraAbstract:TRAINING ANALYSIS OF A 100m HURDLES RUNNER IN THE YEARS 2004 - 2007 Thesis objectives: Examination of influence of training load for personal development of efficiency of Petra Seidlova in 100m hurdles. Method: Method of Autoanalysis of three one - year trainig phases in the period of profesional training. All analysed data about load capacity are taken from daily training - diary of the runner. Results: The basic and special training was mostly influenced by health state of the runner. In the first two recorded seasons training indexes were not that hight as in the last recorded year. However, it diden't influence her dynamic performance. The highest performance progression was recorded in the season 2005/2006, the next year her race performance stagnated.

Cíle práce: Posouzení vlivu tréninkového zatížení na rozvoj výkonnosti Petry Seidlové v běhu na 100 m překážek. Metodika: V práci je použita metoda autoanalýzy třech ročních tréninkových cyklů v etapě vrcholové přípravy. Veškeré analyzované údaje o objemu zatížení jsou získány z tréninkových deníků, které si závodnice po dobu sledovaných sezón vedla. Výsledky: Na tréninkovém zatížení v obecných a speciálních tréninkových ukazatelích měl největší vliv zdravotní stav. V prvních dvou sledovaných sezónách tréninkové ukazatele nedosahovaly takových hodnot, jako v posledním sledovaném roce. N dynamice výkonnosti se to ale neodrazilo. Největší výkonnostní růst byl zaznamenán v sezóně 2005/2006, následující rok závodní výkony stagnovaly.
