- Description:
- Míčovka kulkonosná (Pilularia globulifera – Marsileaceae, Pteridophyta) je evropský endemit se zřetelným subatlantským rozšířením. V současné době je ohrožena a postupně vymírá na území celého svého areálu. Míčovka kulkonosná byla znovu objevena pro květenu České republiky po téměř 70 letech. Nová lokalita byla nalezena v roce 2007 na rybníce nedaleko Studené na úpatí Javořice na Českomoravské vrchovině (Ekrtová a kol. 2008). v Příspěvku jsou shrnuty poznatky o celkovém rozšíření druhu, rozšíření v ČR a ekologické nároky druhu. and Pilwort (Pilularia globulifera – Marsileaceae, Pteridophyta) is a European endemic species with subatlantic distribution. At present, it is endangered and is gradually becoming extinct in the whole area of its natural distribution. Pilwort has been rediscovered in the Czech Republic after almost 70 years. The new locality was found at the base of Javořice hill in the Bohemian-Moravian Highlands in 2007. General information is presented on habitat, ecological preferences and distribution area.

38976. Micro tangent sets of continuous functions

- Type:

- Subject:
- typical continuous function, Brownian motion, Takagi’s function, and Weierstrass’s function
- Language:
- English
- Description:
- Motivated by the concept of tangent measures and by H. Fürstenberg’s definition of microsets of a compact set A we introduce micro tangent sets and central micro tangent sets of continuous functions. It turns out that the typical continuous function has a rich (universal) micro tangent set structure at many points. The Brownian motion, on the other hand, with probability one does not have graph like, or central graph like micro tangent sets at all. Finally we show that at almost all points Takagi’s function is graph like, and Weierstrass’s nowhere differentiable function is central graph like.

- Language:
- English
- Description:
- Monitoring of tectonic movements along three active faults of Dinaric (NW-SE trending) fault system in W Slovenia using TM 71 extensiometers was set up in 2004. After two and a half years of measurements clear trends of displacement were recorded. The average left-lateral displacement along a crack in the inner fault zone of the Idrija fault in Učja valley was reading 0.38 mm/year. Short term (10 months) rates were even greater and reached the value of 0.54 mm/year. Since the Idrija fault is considered generally to be dextral strike-slipping, the observed left-lateral displacement can be explained by variations in principle stress. Raša fault monitoring site at the foot of Vremščica Mt. established an average reverse uplift of hanging wall (SW) block of 0.24 mm/year and left-lateral displacement of 0.16 mm/year. Short term (9 months) vertical displacements reached the value of 0.53 mm/year. The inclined displacement is in agreement with geological and seismological observations. In the Postojna cave system two instruments were installed at the fault which extends parallely to Predjama fault zone. The average vertical displacement rate at Postojna 1 site was 0.01 mm/year. Both devices recorded similar reaction which can be attributed to 12 July, 2004 (Mw=5.2) earthquake with an epicentre 70 km away from the measuring site. Since there were no other stronger earthquakes in the vicinity and time span of monitoring, no other correlations were established with earthquake activity. The observed displacement rates along all three monitored faults of up to 0.5 mm/year are consistent with the regional deformation rate in W Slovenia established from GPS measurements which is of the order of 2 mm/year., Andrej Gosar, Stanka Šebela, Blahoslav Košťák and Josef Stemberk., and Obsahuje bibliografii

38978. Micro-ecology and some related aspects of C4 plants living in Europe
- Creator:

- Language:
- Multiple languages
- Description:
- The number of C4 plants living in Europe is increased to 120, and data on geographic origin, metabolic subtype, microecology and biotype, are given and compared with previous data. Our data agree with current ideas regarding the origin and biotype of the C4 plants, and only partially regarding ecology. At present, many C4 plants grow on disturbed sites or in stressed conditions, but ťhere is a lesser number of xerophytes than is currently thought and, conversely, some of them grow in favourable conditions. Among the latter mentioned, hydrophytic plants stand out because of their relatively great number and originality, as well as because no previous work on the ecology of C4 plants has indicated this.

38979. Micro-PIV characterization of laminar developed flows of Newtonian and non-Newtonian fluids in a slit channel

- Type:

- Subject:
- micro-PIV, slit, channel, non-Newtonian, blood analogue, xanthan, and laminar
- Language:
- English
- Description:
- Comprehensive knowledge of hydrodynamics inside the feeding channels of spira-lwound membrane modules is recognized as crucial for the efficient operation of such separation equipments. Slits are laboratory models widely used to mimic the fundamentals of hydrodynamics and mass transfer in spiral-wound membrane modules. In this work micro-PIV was the technique chosen to characterize fully developed laminar flows in a slit for both Newtonian and non-Newtonian fluids. Experiments with water, water-glycerol and water-glycerol-xanthan were carried out at different flow rates, ranging from 4.3. to 25.3 L/h. The ternary mixture water-glycerol-xanthan simulates the non-Newtonian rheological behavior of blood. The other fluids are Newtonian and exhibit different viscosities. The fluids rheology was characterized making recourse to a viscometer. Using micro-PIV, velocity maps at several depths of the channel were obtained. As expected, results showed that the Newtonian fluids flows exhibit parabolic profiles typical of laminar developed flows in slits. On the other hand, slightly flattened profiles characterize the non-Newtonian fluid flows. Comparisons with the analytical solutions for laminar developed flows in rectangular slits are very encouraging. and Obsahuje seznam literatury

- Description:
- The objective of this study was to assess a possible link between microalbuminuria (MA), a major ri sk factor of the cardiorenal syndrome and the brain natriuretic peptide (BNP), a marker of cardiac hypertrophy. Two kidney-one clip (2K-1C) renovascular hypertension was induced in 24 male Wistar rats (weighing 220-250 g). Rats were randomized into four groups for 8 weeks: Sham, not treated; Bos, treated with bosentan; Cap, treated with captopril; Bos/Cap, treated with both drugs. Blood pressure, plasma BNP and transforming growth factor β1 (TGF-β1) concentrations, microalbuminuria and creatininemia as well as cardiac mass, BNP, α- and β-myosin heavy chain (MHC) gene expression and kidney histology were determined. Following stenosis, Sham rats developed hypertension (p<0.001), an increase in BNP (p<0.05) and TGF-β1 (p<0.005) concentrations, creatinine levels (p<0.001), and urinary albumin (p<0.001). Under drug treatment, decreases in blood pressure (p<0.001), creatinine levels (p<0.05), plasma TGF-β1 (p<0.005) and BNP (p<0.05) concentrations, were co ncomitant with the absence of MA which was significantly correlated with reductions in cardiac mass (p<0.05) and hypertrophy markers (BNP and β-MHC gene expression) (p<0.005) as well as in renal fibrosis. These findings suggest a potential link between microalbuminuria evolution and BNP as well as a possible effect of microalbuminuria-lowering therapy on halting the progression, or even inducing the regression of cardiac hypertrophy., Y.
