Background: The results of studies examining the response to experimental pain during the menstrual cycle are conflicting because of differences in the definitions of the menstrual period, outcome measures and types of experimental pain stimulation. So far, there have been only a few studies correlating experimental pain with the levels of gonadal ...

AbstractTorrefaction is considered as a method for producing biofuels with improved characteristics compared to those of the “raw” biomass (higher calorific value, moisture resistance, better grindability). The torrefaction process is an endothermic process that is usually carried out in a gaseous atmosphere in the absence of oxygen. To reduce the ...

Fast pyrolysis of lignocellulosic biomass is one of the most promising methods of the production of renewable fuels. However, an optimization of the conditions of bio-oil production is not possible without comprehensive analysis of the composition of formed products. There are several methods for the determination of distribution of products formed...
ABSTRACT Nitrogen (N) strongly affects plant growth. However, little is known about the effects of the ammonium/nitrate ratio on pakchoi (Brassica rapa), especially its glucosinolates (GSs) contents which are involved in plant defense and many of them benefit to human health. The aim of this study was to evaluate the effects of a constant N supply ...

AbstractThe effects of aluminium (Al)-induced alterations on elongating radicles of Cicer arietinum L. were studied in relation to growth and biochemical markers of oxidative stress. Elongating radicles (c. 1 mm) were treated with 0–3 mM aluminium chloride (pH 4.5) for seven days at room temperature (26 ± 2°C). The results indicated that exposure t...
V této práci jsem se zabýval sušením bio materiálů. Zpracoval jsem rešerši typů sušek a vzájemně je porovnal. Z těchto typů sušek jsem vybral vhodné typy pro sušení biomasy. Dále jsem se zabýval fluidními suškami a provedl základní bilanční výpočet pro předběžný návrh fluidní sušky. / This thesis is focused on drying of biomaterials. I researched a...
Tato práce se zabývá návrhem biomasového parního kotle spalujícího agrární biomasu, konkrétně slámu. Součástí práce je kompletní tepelný výpočet kotle. Tepelný výpočet je pak ještě zopakován pro palivo o větší vlhkosti a řeší dopady spalování tohoto paliva na vlastnosti kotle. / This master’s thesis deals with design of a boiler for agricultural bi...

The growing importance of bio-based products, combined with the desire to decrease the production of wastes, boosts the necessity to use wastes as raw materials for bio-based products. A waste material with a large potential is spent sugar beets, which are mainly used as animal feeds or fertilizers. After hydrothermal treatment, the produced chars ...
