Subject:
two-stage pump, turbine, angle of attack, and modeling
Language:
English
Description:
CFD simulation is aimed on the two-stage pump operation modeling in the pump and turbine regime. The flow analysis will be focused on the proper angle of wicket gates attack and on the separation localization. This investigation should bring the geometry modifications that will increase the hydraulic efficiency. The computational model was created in preprocessor GAMBIT and software Fluent will be used for the finite computation.

2. Osudy deprivovaných dětí - cesta sirotků z Terezína za Annou Freudovou

model:article and TEXT
Subject:
holocaust, Terezín, koncentrační tábor, adaptace, trauma, concentration camp, and adaptation
Language:
Czech
Description:
Článek se zabývá propojením informací o skupině dětí, které přišly v útlém věku o rodiče během 2. světové války, byly umístěny do koncentračního tábora Terezín a po osvobození Československa poslány do Anglie, kde jim byla poskytnuta všestranná podpora. Článek se zaměřuje na dva zdroje psychoanalyticky orientovaných autorek – studii Anny Freudové a Sophie Dannové s názvem Experiment se skupinovou výchovou (Freud a Dann, 1951), která je ukázkou ročního sledování vývoje deprivovaných dětí, a studii Sarah Moskovitzové (1983, 1985) dokumentující další vývoj terezínských dětí v dospělosti. Z psychologického hlediska sledování ukazují na možnost dobré adaptace i po těžké deprivaci v dětství. Z historického hlediska jde o dokumentaci osudů židovských dětí spojených pobytem v Terezíně a angažmá řady zainteresovaných pomocníků včetně Anny Freudové. and The article deals with connecting information about a group of children who lost their parents at an early age during World War II, were placed in the Terezín concentration camp and after the liberation of Czechoslovakia were sent to England, where they were provided with comprehensive support. The article focuses on two sources of psychoanalytically oriented authors - a study by Anna Freud and Sophie Dann entitled An experiment with group upbringing (Freud and Dann, 1951), which is an example of annual monitoring of the development of deprived children and a study by Sarah Moskovitz (1983, 1985) documenting further development of Terezín children in adulthood. From a psychological point of view, observations indicate the possibility of good adaptation even after severe deprivation in childhood. From a historical point of view, this is a documentation of the fate of Jewish children connected with their stay in Terezín, the engagement of a number of interested helpers, including Anna Freud.

Description:
To explore the effects of water column nutrient loading on photosynthesis of the submerged macrophyte Vallisneria natans (Lour.) Hara during the growth season (June to October), we determined the diurnal and seasonal variation in rapid light curves of plants cultivated under 4 different nutrient concentrations (N-P [mg L-1]: (1) 0.5, 0.05; (2) 1.0, 0.1; (3) 5.0, 0.5; (4) 10.0, 1.0). Nutrient concentration significantly affected the magnitude of the rapid light curves of V. natans, but not the direction of their diurnal variations. At low nutrient conditions (N-P 1 [mg L-1]: 0.5, 0.05), the maximum relative electron transport rate (rETRmax) and minimum saturating irradiance (Ek) derived from rapid light curves were significantly lower than those of other treatments, and their seasonal variations were suppressed. These results indicated that photosynthesis of V. natans was inhibited by the lack of nutrients in water column. At high nutrient conditions (N-P 4, [mg L-1]: 10.0, 1.0), there was an increase in photosynthetic rate in the light-limited region of rapid light curve (α), and a decrease in rETRmax and Ek, relative to moderate nutrient conditions (N-P 2, [mg L-1]: 1.0, 0.1). In addition, at high nutrient concentrations, the rapid light curves of V. natans reached a plateau, and then markedly declined compared with those at the lower nutrient levels, especially in July and August. These results suggested that V. natans were adapted to low-light environments in the high-nutrient loading treatment., X. L. Cai ... [et al.]., and Obsahuje bibliografii
