Acta Univ. Agric. Silvic. Mendelianae Brun. 2008, 56(1), 19-24 | DOI: 10.11118/actaun200856010019  

In the April of 2007, pseudomyiasis was detected in alimentary tract of two years old boy from South Moravia (Czech Republic). Contamination was caused by larvae of family Calliphoridae (Diptera), accidentally consummated with half-rotten fruits from bio compost. It is the first recent documented case of pseudomyiasis, and is closely connected with bio waste and ecological waste disposal. Usage of organic waste composting is increasing all around the world, motivated by demand for maximum recycling. While workrooms of bigger compost facilities are usually separated from public, waste containers in front of the houses or small composts in the gardens...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2008, 56(1), 25-30 | DOI: 10.11118/actaun200856010025  

The contemporary trend is using probiotic cultures in fermented food production. They can be used as starter cultures and for their positive effect on human health. Probiotics are defined as living microorganisms present in food which consumed in adequate amounts affects positively the intestinal microflora's composition and balance and thus human health itself. Cultures of these bacteria have to be of human origin and be able to survive the passage through the gastrointestinal tract. They also have to be able to multiply on the site of action (in intestine) and must not be toxic or pathogenic. Unfortunately, even some probiotic cultures can be counted...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2008, 56(1), 137-142 | DOI: 10.11118/actaun200856010137  

Permeability of wood is a wood property which strongly affects a process of drying wood, as well as steaming, boiling and wood impregnation. The low permeability of the most industry treated wood causes investigating the ways which increase the permeability of wood. The one of the considered methods is drying of wood with the aid microwave radiation which causes rotation and friction of water molecules, thus the temperature and the pressure inside the wood are growing up. As a result of raised pressure are crackled cell walls which makes the wood structure more permeable in transverse direction, but in longitudinal direction the wood speciemens treated...

The paper informs of N, P, K, Ca and Mg-contents in the selected organs (tissues) of 4-year old Norway spruce (Picea abies /L./ Karst.) and 3-year old European beech (Fagus sylvatica L.) transplants after two years of Mg fertilization (100 kg Mg.ha^-1.year^-1) in the form of magnesium sulphate, and N fertilization (100 kg N.ha^-1.year^-1) in the form of ammonium sulphate. Analyses of buds, needles/leaves, bark and wood of above-ground part, fine roots (≤ 1 mm) and small-diameter roots (> 1 mm) showed that the greatest amounts of uptaken nutrients are in both tree species stored in assimilatory...

Effects of small mammals were studied on the regeneration of trees in a forest reserve and on forest plantation in the area of the Kelečská pahorkatina Upland with a view to stands of European beech (Fagus sylvatica). Inspection of bark damage was carried out and artificial regeneration was markedly more susceptible to damage (p < 0.01). Of the total number of monitored beech trees 57.5% were damaged in artificial regeneration compared to 12.7% in natural regeneration and 15% died as against 0%. The only pest proved by trapping was Myodes glareolus although damage of tree bases could mean damage caused by species of the genus Microtus....

This work deals with using of new functional elements of furniture. The aim of the work was to design and to produce simple, light and comfortable armchair which could be supplemented with an inner replaceable element. Thanks of interposition of this component in to the basic armchair corpus it could be achieved different materials stiffness of sitting according to the specific user's needs (e.g. according to orthopedic needs of the user). Next advantages are various coloration and creative style so it could be easily evocated the atmosphere not only of routine but also of festive sitting according to user's images, emotional moods or reconciliation...

Results of an analysis of dipteran pests composition and changes of their importance in agricultural, horticultural and ornamental plants during the 20th century are given. Even 89 Diptera species have been registered as pests of these plants (1.1 % of all species known in the Czech Republic). Of these ca 14 (16%) species caused regular and important and other 23 (26%) species occasional damages. The remaining 52 (58%) species are unimportant, local and sporadic pests. Only small changes (10% maximally) in the species composition of more important dipteran pests have been registered during the century.

Je druh Moniezia trigonophora Stiles et Hassall, 1893 (Cestoda, Anoplocephalidae) cizopasníkem kamzíka horského (Bovidae) v České republice?

A revision was performed of the material of tapeworm Moniezia trigonophora Stiles et Hassall, 1893, the finding of which in the territory of the Czech Republic in the host Rupicapra rupicapra (L., 1758) was mentioned by Lamka et al. (2007a, b).After the revision of the material the species M. trigonophora is not a parasite of R. rupicapra in the Czech Republic but tapeworms from M. benedeni species complex parasitize this host in Lusatian Mountains (compare in Kotrlý and Kotrlá-Erhardová, 1970).
