This article analyses the processes of creating the township on the example of Borne Sulinowo, one of the youngest cities in Poland. The collapse of the communism in the Centre and Eastern Europe caused, that Poland had made efforts for the revitalization of areas occupied by Soviet armies. Borne Sulinowo, a small city located in the north-western Poland, suffered the same fate as desolation of its areas after the departure of the Soviet Army and anew settlement by the civil settlers. Issues brought up in the article are focusing on problems of the adaptation of the settlers to the new cultural environment, on shaping local bonds and on the degree of the identification with the new place of residence.
Changes in leaf growth, net photosynthetic rate (PN), incorporation pattern of photosynthetically fixed 14CO2 in leaves 1-4 from top, roots, and rhizome, and in essential oil and curcumin contents were studied in turmeric plants grown in nutrient solution at boron (B) concentrations of 0 and 0.5 g m-3. B deficiency resulted in decrease in leaf area, fresh and dry mass, chlorophyll (Chl) content, and PN and total 14CO2 incorporated at all leaf positions, the maximum effect being in young growing leaves. The incorporation of 14CO2 declined with leaf position being maximal in the youngest leaf. B deficiency resulted in reduced accumulation of sugars, amino acids, and organic acids at all leaf positions. Translocation of the metabolites towards rhizome and roots decreased. In rhizome, the amount of amino acids increased but content of organic acids did not show any change, whereas in roots there was decrease in contents of these metabolites as a result of B deficiency. Photoassimilate partitioning to essential oil in leaf and to curcumin in rhizome decreased. Although the curcumin content of rhizome increased due to B deficiency, the overall rhizome yield and curcumin yield decreased. The influence of B deficiency on leaf area, fresh and dry masses, CO2 exchange rate, oil content, and rhizome and curcumin yields can be ascribed to reduced photosynthate formation and translocation. and Deeksha Dixit, N.

We investigated the renal response to direct renal nerve stimulation, 2 weeks following reversal of 24-h unilateral (left) ureteric obstruction. Renal nerve stimulation caused a 13-15 % fall in renal blood flow, in 4 groups of anesthetized rats following ureteric obstruction (n=9) or a sham operation (n=7) both with (n=9) and without (n=7) treatment with the mixed ETA/B receptor antagonist, bosentan. In the sham-operated rats, renal nerve stimulation did not change glomerular filtration rate but reduced urine flow rate (37±3 %, P<0.001), and absolute (38±4 %, P<0.001) and fractional (35±5 %, P<0.01) sodium excretion. Following unilateral ureteric obstruction, renal nerve stimulation increased glomerular filtration rate by 22±3 % (P<0.01), but reduced urine flow rate (14±2 %, P<0.001) and fractional sodium excretion (23±5 %, P<0.01). Bosentan treatment had no effect on baseline or renal responses to renal nerve stimulation in the sham group but normalized the renal response to renal nerve stimulation in the unilateral ureteric obstruction group. We conclude that 14 days after a 24-h period of unilateral ureteric obstruction there is an increase in GFR in response to direct renal nerve stimulation, which is due, in part, to the actions of endothelin at the time of obstruction., F.

Boseova-Einsteinova kondenzace (BEC) má dlouhou a bohatou historii, jejíž počátky sahají do poloviny dvacátých let minulého století. V tomto článku si ji krátce projdeme a připomeneme si některé etapy vývoje fyziky, které umožnily naše úspěšné bádání BEC v plynech. Pak probereme, co všechno takové hledání obnášelo. V diskusi půjdeme nad rámec obvyklého technického popisu a pokusíme se zodpovědět určité otázky, jež dnes často slýcháváme, ale o nichž se ve svých dosavadních publikacích nezmiňujeme. Jsou to otázky typu: Jak jste na ten nápad přišli a proč jste se ho rozhodli uskutečnit? Věděli jste, že se to podaří? Jak dlouho vám to trvalo a proč? Pojednáme o některých svých oblíbených experimentech, které jsme v BEC prováděli. Nakonec se ještě krátce zmíníme o tom, proč si optimisticky myslíme, že BEC může být dosaženo s téměř libovolným druhem atomů, jež lze v magnetickém poli zachytit. V celém článku se pokoušíme vysvětlit, čím je Boseova-Einsteinova kondenzace v zředěném plynu tak zajímavá, jedinečná a experimentálně náročná., Eric A. Cornell a Carl E.

Previous research suggested that several genetic polymorphisms are associated with increased risk of ischaemic stroke (IS) in young adults. However, the predictive biomarkers of IS in young adults are still unclear. Our aim was to assess the contribution of modifiable and genetic factors in IS in young adults. In total, 40 stroke patients and 40 healthy controls aged 20 to 50 years were recruited. Data on modifiable factors were collected, then participants were genotyped for seven SNPs linked to thrombophilia: ACE rs1799752, PAI-1 rs1799889, APOE rs1412 and rs429358, FV rs6025 and rs1800595, and FII rs62623459. Significantly increased risk factors: hypertension and dyslipidaemia in stroke patients compared with the controls: 50.0 % vs 27.5 % and 75.0 % vs 40.0% (P = 0.039 and P = 0.002, respectively) were observed. Stroke patients compared with controls did not differ in distribution of ACE, APOE, FV, and FII variants. The 4G4G homozygotes of the PAI-1 gene were significantly more prevalent in stroke patients compared to the controls: 42.5 % vs 17.5 %, (P = 0.033). In the group with the small vessel occlusion subtype of stroke, statistically significant overrepresentation of 4G4G homozygotes and frequency of the 4G allele compared with controls: 57.1 % vs 17.5 % and 0.7 vs 0.45 (P = 0.026 and P = 0.03, respectively) were observed. Independent predictors of stroke incident were: dyslipidaemia (OR (95% CI) = 4.2 (1.4–12.4)) and 4G4G genotype (OR (95% CI) = 3.9 (1.1–13.7)). These results confirm the contribution of dyslipidaemia and 4G4G genotype in the increased risk of IS in young Bosnian adults.
Mnohočásticové soustavy vzájemně interagujících fermionů (např. atomová jádra) vykazují řadu bosonových vlastností. Jejich původ lze hledat jak v interakcích, které fermiony svazují do párů, tak v kvantování vibračních a rotačních kolektivních módů pohybu. Interakce bosonových a fermionových stupňů volnosti mohou představovat faktickou realizaci supersymetrie v mnohočásticové fyzice. O přesný mikroskopický popis těchto jevů se snaží techniky bosonového mapování., Pavel Cejnar., and Obsahuje seznam literatury
