- Subject:
- Minkowski content, Kneser function, Brownian motion, and Wiener sausage
- Language:
- English
- Description:
- We show that whenever the $q$-dimensional Minkowski content of a subset $A\subset \mathbb R^d$ exists and is finite and positive, then the “S-content” defined analogously as the Minkowski content, but with volume replaced by surface area, exists as well and equals the Minkowski content. As a corollary, we obtain the almost sure asymptotic behaviour of the surface area of the Wiener sausage in $\mathbb R^d$, $d\geq 3$.

- Description:
- This study on Alois Klar (1763-1833) focuses mainly on his achievements as a pedagogue and his work for the visually impaired. Methodologically, it draws on Theodor Adorno, Max Horkheimer and Michel Foucault, enabling us to view the evolution of social care as a concomitant of the emerging modern state and integral to its structure. The study presents an analysis of the beginnings of Klar’s Prague institute for the visually impaired against a background of rapid changes in medicine, the scope of the state, and educational thinking. At a time of compulsory school attendance and new approaches to education, when the state demanded the active participation of its subjects/citizens in propagating its aims and the values of society as a whole, the blind and partially sighted were given access to a full and systematic education. We also present data concerning Klar’s educational work and thinking (he taught in Litoměřice and at Prague University), and examine the internal workings of the newly established institute - one of the first of its kind in Europe - and its contacts with the medical discourse of the emerging science of ophthalmology., Marek Fapšo., and Obsahuje bibliografické odkazy

- Subject:
- Alois Musil and topographer
- Language:
- English
- Description:
- Alois Musil, the Czech Old Testament scholar, priest, topographer and explorer of the unexplored Arabic lands of the Near East before World War I left the scholarly world an immense wealth of information about the Biblical, historical, ethnographical, and archaeological sites he visited, described, noted, and commented on during the years ca. 1896 to 1917. During that time he served as a valuable mediator to the Central Powers (Mittel-Mächte) and the Ottoman Empire seeking to make peace between rival Arab tribes in Arabia. Since he knew the sheikhs of all tribes, and since he was acknowledged by the tribe of the Rualla as sheikh Musa, he was successful in making peace between the tribes of the Rualla, Ibn Rashid, and Ibn Saud. In this way he raised approximately 30,000 camel riders to aid the Ottoman Empire in the fight against the British army in Arabia. Initially his efforts were successful, however due to the shortsightedness of the Ottoman Empire, the British and French military and policy finally triumphed over the tribal confederacies by turning them away from Constantinople. The various episodes of Alois Musil’s sojourn into the Arabian desert, as well as his negotiations with the tribes from November/December 1914 until the middle of April 1915, are described and commented on in this article.

1685. Alois Rašín - temperamentní revolucionář ve službách kontinuity

- Subject:
- Alois Rašín, 28. říjen 1918, První zákon, Základní zákon státu, First Law, and Founding Law of the State
- Language:
- Czech
- Description:
- Beside Antonín Švehla, it was - without question - Alois Rašín, who influenced the process of the coup the most. His vision of the coup was not dull, simple or technological; it was a perfectly prepared and managed action, which was also to be enjoyed by its participants. In the centre of Rašín's thoughts were the preparations of the law drafts (also called The Founding Law of the State and above all The First Law), which should have given a legal framework to the new state. A coup that did not get out of hand and which was, once completed, immediately sealed by a law was his ideal but attainable vision. Rašín was probably the only one who tried to prepare such a law. No other proposal is known. All of this attests to his capabilities as statesman and his ability to act. and Článek zahrnuje odkazy pod čarou

- Subject:

- Language:

- Description:
- Two new yellow rice chlorophyll (Chl) b-less (lack) mutants VG28-1 and VG30-5 differ from the other known Chl b-less mutants with larger amounts of soluble protein and ribulose-1,5-bisphosphate carboxylase/oxygenase small sub-unit and smaller amounts of Chl a. We investigated the altered features of Chl-protein complexes and excitation energy distribution in these two mutants, as compared with wild type (WT) rice cv. Zhonghua 11 by using native mild green gel electrophoresis and SDS-PAGE, and 77 K Chl fluorescence in the presence of Mg2+. WT rice revealed five pigment-protein bands and fourteen polypeptides in thylakoid membranes. Two Chl b-less mutants showed only CPI and CPa pigment bands, and contained no 25 and 26 kDa polypeptides, reduced amounts of the 21 kDa polypeptide, but increased quantities of 32, 33, 56, 66, and 19 kDa polypeptides. The enhanced absorption of CPI and CPa and the higher Chl fluorescence emission ratio of F685/F720 were also observed in these mutants. This suggested that the reduction or loss of the antenna LHC1 and LHC2 was compensated by an increment in core component and the capacity to harvest photon energy of photosystem (PS) 1 and PS2, as well as in the fraction of excitation energy distributed to PS2 in the two mutants. 77 K Chl fluorescence spectra of thylakoid membranes showed that the PS1 fluorescence emission was shifted from 730 nm in WT rice to 720 nm in the mutants. The regulation of Mg2+ to excitation energy distribution between the two photosystems was complicated. 10 mM Mg2+ did not affect noticeably the F685/F730 emission ratio of WT thylakoid membranes, but increased the ratio of F685/F720 in the two mutants due to a reduced emission at 685 nm as compared to that at 720 nm. and Zhu-Fang Lin ...

1689. Alterations in electron transport characteristics during senescence of Cucumis cotyledonary leaves. Analysis of the effects of inhibitors

- Type:

- Subject:
- atrazine, cucumber, DCMU, dibromothymoquinone, KCN, photosystems 1 and 2, plant age, and thylakoid proteins
- Language:
- Multiple languages
- Description:
- Cotyledonary leaves of Cucumis sativus cv. Poinsette exhibited senescence-induced losses in chlorophyll (Chl) and protein contents within three weeks since germination. Chl and protein concentrations in cotyledonary leaves approached maximum on 6th d after germination and they declined to 50 and 41 %, respectively, by the 20th day of growth. Activities of both photosystem (PS) 2 and PS1 decreased by 33 and 31 %, respectively, on the 20th day, compared to the control 6th day. Changes in sensitivity of PS2 to inhibitors like atrazine and dibromothymoquinone and sensitivity of PS1 to KCN accompanied the changes in PS2 and PS1 activities. Hence both the acceptor side of PS2 and the donor side of PS1 are affected by senescence-induced changes in cucumber cotyledonary leaves. and J. S. S. Prakash, M. A. Baig, Prasanna Mohanty.

- Subject:

- Language:

- Description:
- Endothelin-1 (ET-1) acts on ETA and ETB receptors and has been implicated in hemorrhagic shock (shock). We determined effect of shock and resuscitation by hypertonic saline (saline) or centhaquin on ETA and ETB receptor expression. Rats were anesthetized, a pressure catheter was placed in the left femoral artery; blood was withdrawn from the right femoral artery to bring mean arterial pressure (MAP) to 35 mm Hg for 30 min, resuscitation was performed and 90 min later sacrificed to collect samples for biochemical estimations. Resuscitation with centhaquin decreased blood lactate and increased MAP. Protein levels of ETA or ETB receptor were unaltered in the brain, heart, lung and liver following shock or resuscitation. In the abdominal aorta, shock produced an increase (140 %) in ETA expression which was attenuated by saline and centhaquin; ETB expression was unaltered following shock but was increased (79 %) by centhaquin. In renal medulla, ETA expression was unaltered following shock, but was decreased (-61 %) by centhaquin; shock produced a decrease (-34 %) in ETB expression which was completely attenuated by centhaquin and not saline. Shock induced changes in ETA and ETB receptors in the aorta and renal medulla are reversed by centhaquin and may be contributing to its efficacy., S. Briyal, R. Gandhakwala, M. Khan, M. S.
