Czech puppet theatre in global contexts: roots, theories and encounters
This article is both an introduction to this volume as well as to the rich and enchanting world of Czech puppet theatre, with its unique combination of transnational and geographically and cultural distinctive features. Pavel Drábek's essay, incorporated in this introduction, revisits the early modern roots of Czech puppet theatre, suggesting the possible missing links between the early practices, as documented in the travelling performers' tradition, and the tradition of the marionettists of the last two centuries. The introduction traces the developments of the Czech puppet theatre into the twentieth century and its impact on cinema as well as its key role in the shaping of modern theatre theory under the aegis of the Prague School
Efficiency of Voluntary Consumption of Amino Acid-chelated Iron in Preventing Aaemia of Suckling Piglets
The aim of the study was to evaluate efficiency of voluntary access to amino acid-chelated iron in the form of mineral supplement in preventing anaemia of piglets. Piglets in group 1 (n = 60) were offered ad libitum the iron mineral supplement (Fe 110 g·kg-1) from the 2nd to the 14th day of life. Piglets in group 2 (n = 30) were given 200 mg Fe3+ as iron dextran i.m. on day 3. On day 7, haemoglobin concentration (Hb) (P < 0.05), packed cell volume (P < 0.05), red blood cell count (P < 0.01) and plasma iron concentration (P < 0.01) in group 1 were lower compared to group 2. On day 14 and 21 no significant differences were found between the two groups. At the time of weaning (day 28), the voluntary access to iron did not prevent 8 % of piglets from becoming anaemic (Hb < 80 g·l-1). Body weights were comparable in the 2 groups. Haemoglobin, packed cell volume, erytrocyte Iron deficiency anaemia is a serious problem in swine production. The piglet can receive only ca 1 mg Fe per day from sow´s milk (Csapó 1995; Kleinbeck and McGlone 1999). However the daily requirement during suckling period is ca 7-10 mg Fe (Venn et al. 1947). The iron deficit results in clinically apparent anaemia 10-14 days postpartum (Framstad and Sjaastad 1991; Zimmermann 1995). Different forms of iron supplementation hav
Periodic solutions for some phi-Laplacian and reflection equations
This work is devoted to the study of the existence and periodicity of solutions of initial differential problems, paying special attention to the explicit computation of the period. These problems are also connected with some particular initial and boundary value problems with reflection, which allows us to prove existence of solutions of the latter using the existence of the formerThe work was partially supported by FEDER and Ministerio de Economía y Competitividad, Spain, project MTM2013-43014-P.

Efficiency of Carbonyl Iron in Prevention of Anaemia in Piglets
The aim of this study was to evaluate efficiency of elemental iron preparation in the form of carbonyl iron in prevention of iron deficiency in piglets. The piglets in group I (n = 14) were given 210 mg of carbonyl iron orally at the age of 3 days. The piglets in group II (n = 15) received 210 mg of carbonyl iron orally on days 3 and 9. In group III (n = 14) the piglets were injected i.m. with 200 mg Fe 3+ as iron dextran. Fourteen days after birth, haemoglobin concentration in group I started to decrease and the piglets developed anaemia. In group II, at the age of 28 days, Hb dropped below 80 g/l and the piglets developed anaemia. Under conditions of this trial, the oral administration of carbonyl iron did not prevent development of iron deficiency in piglets. , haemoglobin, packed cell volume, neonatal period, iron dextran, oral administration Anaemi
Effect of an Acute Iron Overdose on PMN Cells Chemiluminescence and Indices of Inner Environment in a Swine Model
The objective of the study was to evaluate the effect of an acute iron dextran administration on polymorphonuclear cells chemiluminescence and indices of inner environment in piglets. Piglets in the experimental group (n = 16) were given 2000 mg (20 ml) Fe3+ in the form of iron dextran i.m. Piglets in the control group (n = 13) were given the same amount of physiological saline. Blood was taken before administration, and 1, 4 and 24 hours after. Iron application resulted in a ten times higher concentration of iron in blood plasma in the experimental group. No differences in spontaneous, PMA- and OZP-stimulated chemiluminescence were recorded between the two groups. The increased activities of CK, AST and LDH are indicative of a muscle injury at the injection site. No changes indicating liver or kidney injury were reported. Our study provides evidence of a good safety of iron dextran after parenteral administration
Computing the first eigenpair of the p-Laplacian via inverse iteration of sublinear supersolutions
We introduce an iterative method for computing the first eigenpair
for the -Laplacian operator with homogeneous Dirichlet
data as the limit of as , where
is the positive solution of the sublinear Lane-Emden equation
with same boundary data. The method is
shown to work for any smooth, bounded domain. Solutions to the Lane-Emden
problem are obtained through inverse iteration of a super-solution which is
derived from the solution to the torsional creep problem. Convergence of
to is in the -norm and the rate of convergence of
to is at least . Numerical evidence is
presented.Comment: Section 5 was rewritten. Jed Brown was added as autho
