Grain Quality of Spring Barley from the Testing Sites in the Czech Republic, Crop 2014

Samples of three spring barley varieties from 20 testing sites were analyzed according to the standard ČSN 461100-5. Contents of nitrogenous substances (10.5% –11.4%) and starch (61.1%–64.7%) in spring barley caryopses were favorable. Grain harvested in 2014 was bigger and even in sizes. Sieving fractions over 2.5 mm varied on average around 91.3%. Year 2014 was favorable in terms of barley grain quality, without problems with sprouting. The occurrence of admixtures was adequate and was formed by the admixtures partly usable for malting (grains without hulls, with black tips and grains with awns)

Quality of Winter Barley Grain from the Testing Localities in the Czech Republic, Harvest 2014

Samples of two studied winter barley varieties from 13 testing localities were analyzed according to the standard ČSN 46 1100-5. Based on the standard, sieving fractions over 2.5 mm, total admixtures, admixtures non-usable for malting, admixtures partly usable for malting, grains without hulls, grains with black tips and grains with the awn were assessed. Contents of nitrogenous substances and starch were 10.8 % and 63.9 %, respectively. Grain harvested in 2014 was bigger and even in size. Sieving fractions over 2.5 mm moved on average around 91.6 %. The year 2014 in terms of barley grain quality was very favorable, there was no problem with sprouting, the occurrence of admixtures was the lowest in last three years and the admixtures were mostly partly usable for malting

Barley varieties registered in the Czech Republic after the harvest of 2020

The study presents malting quality and agronomic characteristics obtained during testing of barley varieties in the Czech Republic. After the  harvest of 2020, the following spring barley malting varieties were registered: Amidala, Focus, Greenway, KWS Jessie, LG Belcanto, and LG Stamgast. LG Stamgast was recommended for production of the beer with the protected geographical indication České pivo. In addition, the non-malting spring barley variety RGT Gagarin was registered.

The value of the Kolbach index ranged from 48.6 to 52.1%. Diastatic power was at the optimal level. Degradation of cell walls was also optimal. Friability moved from 89 to 97% and β-glucan content in wort achieved satisfactory values of 65 – 170 mg/l in the given varieties . Wort quality, which is characterized by final attenuation, was at the above average to optimal level of 80.9 – 83.2% in these varieties of spring barley. LG Stamgast showed lower values of proteolytic and cytolytic modification and lower values of final attenuation, which is required for the varieties recommended for the production of the beer with the protected geographical indication České pivo

Barley varieties registered in the Czech Republic after the harvest 2022

After the 2022 harvest, seven new varieties of malting barley were registered in the Czech Republic. After three years of testing, spring barley varieties Ambiana, Gingko, Kimberly, KWS Thalis, LG Ludvik, LG Rhapsody and RGT Proxima were registered. Based on the results obtained, LG Ludvik was recommended for the production of beer with the protected geographical indication 'České pivo'. This variety showed low activity of proteolytic and cytolytic enzymes and low level of final attenuation. The other spring barley varieties (Ambiana, Gingko, Kimberly, KWS Thalis, LG Rhapsody and RGT Proxima) gave sweet wort with extract content in malt dry matter ranging from 82.6 to 84.6%. The varieties Ambiana, Gingko, LG Rhapsody and RGT Proxima had extract contents of more than 83%. Proteolytic modification was high (Kolbach Index above 50%) in the varieties Gingko, LG Rhapsody and RGT Proxima. The β-glucan content in sweet wort below 100 mg/l was recorded in the varieties Gingko and LG Rhapsody. Cell wall degradation (friability 85–94%) and final attenuation (81.7–83.0%) were at optimum levels in Ambiana, Gingko, Kimberly, KWS Thalis, LG Rhapsody and RGT Proxima. Gingko, Kimberly and LG Rhapsody always produced clear sweet wort. Low to zero lipoxygenase activity was found in KWS Thalis

Long-term power outage and preparedness of the population of a region in the Czech Republic - A case study

The power outages that have occurred in recent years around the world point to widespread problems with consequences for the lives and health of the population, but also material damage. This is a case study that focuses on the evaluation of the preparedness of the population of a selected region in the Czech Republic for a long-term power outage. This article deals with a case study that focuses on the evaluation of the preparedness of the population of the Karlovy Vary region in the field of emergency survival. Part of the study is the evaluation of the respondents' answers, which provides an overview of the actual state of preparedness for power outages on a sample group of respondents in the Karlovy Vary region. The research method used was a survey using questionnaires. The obtained information was subsequently statistically evaluated by nonparametric correlation using Kendall's tau(b). From the presented results of the survey, it is clear that the inhabitants of smaller municipalities are better prepared for a power outage and can create basic conditions for emergency survival.Web of Science1323art. no. 1314

Acid/base properties and reactivity of square planar complexes

Complexes of platinum and other transition metals are important compounds with many applications including anticancer treatment. This thesis is based on the computational studies dealing with the properties and reactivity of square planar complexes. We showed that the central metal atom acts as a Lewis acid in standard coordination bonds but is able to interact as a Lewis base when being in contact with a Lewis acid. Substitution(s) of the nonleaving ligand(s) enabled a fine-tuning of the reactivity of Pt(II) compounds
