In this paper, for complete Riemannian manifolds with radial Ricci or sectional curvature bounded from below or above, respectively, with respect to some point, we prove several volume comparison theorems, which can be seen as extensions of already existing results. In fact, under this radial curvature assumption, the model space is the spherically symmetric manifold, which is also called the generalized space form, determined by the bound of the radial curvature, and moreover, volume comparisons are made between annulus or geodesic balls on the original manifold and those on the model space., Jing Mao., and Obsahuje seznam literatury
Voluntary death, particularly when caused by oneself, defies easy understanding. The individual´s life carries immense value in the West and therefore a rather negative attitude toward death predominates. The attitudes towards death found in Confucianism, Buddhism and Shintó are substabtually different - the death of an individual is seen as a natural part of human life. The manner or style of leaving the world is, however, very important since it validates the life that preceded the event. This article focuses of the problem of voluntary death in Japan. It analyzes the Japanese expressions that specify various types of self-killing and deals with traditional religious and social factors that influence atttudes to self-sacrifice and suicide.
Although physical exercise is known to reduce size of infarction,
incidence of ventricular arrhythmias, and to improve heart
function, molecular mechanisms of this protection are not fully
elucidated. We explored the hypothesis that voluntary running,
similar to adaptive interventions, such as ischemic or remote
preconditioning, may activate components of pro-survival (RISK)
pathway and potentially modify cell proliferation. Sprague-Dawley
adult male rats freely exercised for 23 days in cages equipped
with running wheels, while sedentary controls were housed in
standard cages. After 23 days, left ventricular (LV) myocardial
tissue samples were collected for the detection of expression and
activation of RISK proteins (WB). The day before, a marker of
cell proliferation 5-bromo-2'-deoxyuridine (BrdU) was given to all
animals to detect its incorporation into DNA of the LV cells
(ELISA). Running increased phosphorylation (activation) of Akt,
as well as the levels of PKCε and phospho-ERK1/2, whereas BrdU
incorporation into DNA was unchanged. In contrast, exercise
promoted pro-apoptotic signaling - enhanced Bax/Bcl-2 ratio and
activation of GSK-3β kinase. Results suggest that in the rat
myocardium adapted to physical load, natural cardioprotective
processes associated with physiological hypertrophy are
stimulated, while cell proliferation is not modified. Up-regulation
of pro-apoptotic markers indicates potential induction of cell
death mechanisms that might lead to maladaptation in the longterm.
Medical genetic research achieved in last decade many efforts leading to better understanding of inherited basis of human diseases. This will not be possible without the participation of patients and controls. However, the general understanding of the background and possibilities of genetic association studies is very low. It was confirmed by study of university of students. Because of the fair of misuses of the individual genetic information, significant part of participants refused the use of already donated blood samples for genetic testing but agreed with using of buccal swabs for the same analysis. To enhance the general knowledge’s of the population, leading to realistic expectations not just about genetic predictive power but also about the eventual risks in behind will be the major mission in the next years., V.

The contribution explores the Prague origines of the first Prague and Austrian female author of the Enlightenment, Maria Anna Sager, born Rosskoschny (1719-1805). The reconstruction of the carreer of her father Anton Ferdinand Rosskoschny (1679-1734) at the Böhmische Statthalterei - he ended as "Registrator" and "Expeditor" - proves his social ambitions. On the other hand egodocuments of him conserved in the National Archives at Prague reveal the sorrows and the "stress" of the wellestablished fonctioner, not only his fear in front of the people, but also for his reputation, his family and his soul., Helga Meise., and Obsahuje bibliografické odkazy
In the War of the Austrian Succession one of the major turning points was when Maria Theresa was crowned Queen of Bohemia, because this step strengthened the power of the Houseof Habsburg in Central Europe. For people who belonged to the Reformed Church in the Kingdom of Hungary, this meant that they had to live their lives under the rule of a Catholic monarch. Debrecen was the centre of the Reformed Church and the city prepared for this political situation: pastor Mihály Komáromi H. delivered a special sermon to celebrate the coronation. In this sermon he acknowledged the fact that the Habsburgs had right to the Hungarian throne and tried to use this political advantage to improve the situation of the Reformed Church. This sermon became so popular that a manuscript was made from it and it was a popular reading in the Reformed congregations of the countryside., Ádám Hegyi., and Obsahuje bibliografické odkazy
VPS-30-En is a small lexical resource that contains the following 30 English verbs: access, ally, arrive, breathe,
claim, cool, crush, cry, deny, enlarge, enlist, forge, furnish, hail, halt, part, plough, plug, pour, say, smash, smell, steer, submit, swell,
tell, throw, trouble, wake and yield. We have created and have been using VPS-30-En to explore the interannotator agreement potential
of the Corpus Pattern Analysis. VPS-30-En is a small snapshot of the Pattern Dictionary of English Verbs (Hanks and Pustejovsky,
2005), which we revised (both the entries and the annotated concordances) and enhanced with additional annotations. and This work has been partly supported by the Ministry of
Education of CR within the LINDAT-Clarin project
LM2010013, and by the Czech Science Foundation under
the projects P103/12/G084, P406/2010/0875 and
P401/10/0792.
VPS-GradeUp is a collection of triple manual annotations of 29 English verbs based on the Pattern Dictionary of English Verbs (PDEV) and comprising the following lemmas: abolish, act, adjust, advance, answer, approve, bid, cancel, conceive, cultivate, cure, distinguish, embrace, execute, hire, last, manage, murder, need, pack, plan, point, praise, prescribe, sail, seal, see, talk, urge . It contains results from two different tasks:
1. Graded decisions
2. Best-fit pattern (WSD) .
In both tasks, the annotators were matching verb senses defined by the PDEV patterns with 50 actual uses of each verb (using concordances from the BNC [2]). The verbs were randomly selected from a list of completed PDEV lemmas with at least 3 patterns and at least 100 BNC concordances not previously annotated by PDEV’s own annotators. Also, the selection excluded verbs contained in VPS-30-En[3], a data set we developed earlier. This data set was built within the project Reviving Zellig S. Harris: more linguistic information for distributional lexical analysis of English and Czech and in connection with the SemEval-2015 CPA-related task.
