Chemical and mineralogical analyses of plaster samples from State Castle Bečov
Slížková, Zuzana; Koudelková, Veronika; Kozlovcev, Petr; Šterner, Adam
2018 - Czech
Using chemical and microscopic analysis, it was determined that the analyzed sample of bedding mortar from the 13th century (Czech castle Bečov) is the air lime mortar with the quartz and silicate sand enriched by some content of slag grains. The internal plaster from the same building period of the castle was made using the lime-earthen mortar with predominantly silicate sand. The plaster contained an admixture of wood or plant particles, sawdust has been identified.\n\n Pomocí chemické a mikroskopické analýzy bylo určeno, že analyzovaný vzorek malty z 13. stol. je vápenná malta s převážně křemenným a silikátovým pískem a vnitřní omítka z 13. stol. byla provedena z malty vápenohliněné s převážně silikátovým plnivem. Omítka obsahuje příměs dřevěných či rostlinných částic, byly identifikovány piliny. Malta obsahuje kousky strusky.

Proposal for loading tests of bridges - simulation and laboratory experiments
Bayer, Jan; Urushadze, Shota; Černý, Miloš
2018 - English
A new dynamic load testing of bridges is proposed and theoretically investigated. A transient analysis of passing vehicle over a bridge in ANSYS and an analytical program in MATLAB for the transient solution of piecewise linear mechanical structures were developed to assess the effects of the proposed dynamic load on a bridge model. According to the first laboratory experiments, it seems that the proposed travelling impulse load could surpass some of the shortcomings and limitations of the currently applied methods of bridge testing. The investigation is a part of a project aimed at drive-by identification of dynamic properties of bridges and further experimental and analytical research will follow. Keywords: dynamic loading tests; transient analysis; vibrations; vehicle-bridge interaction Available at various institutes of the ASCR

Footbridge in Radotín - wind load according to EN 1991-1-4 and wind tunnel experiments
Göringer, J.; Hračov, Stanislav; Macháček, Michael
2018 - Czech
Due to the atypical design of the footbridge in Radotín the procedures for evaluation of the force coefficients presented in EN 1991-1-4 were experimentally verified in the wind tunnel. For the lack of the information about the structure behaviour on the edge of the aerodynamic instability the critical velocity for flutter was experimentally verified as well. The paper presents comparison of the approaches from EN 1991-1-4 with the results of the experiment. S ohledem na atypickou konstrukci lávky v Radotíně bylo nutno v rámci statického ověření řešit nestandardní účinky zatížení větrem, kdy EN 1991-1-4 poskytuje pro takto atypické konstrukce jen málo podpory. Zatížení větrem u takovéto konstrukce nevystupuje pouze jako náhradní statický účinek, ale zejména je nutné posoudit případné ztráty aerodynamické stability. Příspěvek předkládá postup stanovení problematiky podle EN 1991-1-4 včetně porovnání s výsledky z větrného tunelu.

Methodology for assessing social effectiveness of institutions executing public policies
Bohatá, Marie; Putnová, A.; Rašticová, M.; Bédiová, M.; Cebáková, A.
2018 - Czech
The methodology certified by the Technological Agency of the Czech Republic (TAČR) is based on an original concept of social effectiveness of public administration reflecting modern trends in governance supporting the trustworthiness of the public service and emphasising the public interest, openness, participation, and integrity. The self-assessing methodology aimed at creating a self-learning organisation is developed for the internal needs of public administration. It has a modular character and encompasses such building blocks as strategic management and coordination, operational management and performance, external communication, ethics and integrity, and HR policy and social climate. It can be used at different organisational levels within the state administration and the self-government. It is user-friendly providing the user with an immediate feedback as well as a guidance in generating improvement actions. Simultaneously, the methodology is of inspiring nature, as it serves as a repository of good practices. Metodika certifikovaná TAČR je založena na původním konceptu společenské efektivnosti veřejné správy, který reflektuje moderní trendy v oblasti vládnutí podporující důvěryhodnost veřejné služby a zdůrazňuje především veřejný zájem, otevřenost, participaci a integritu. Metodika má sebehodnotící charakter a je navržena pro vnitřní účely s cílem vytvářet učící se organizace. Má modulární charakter a jednotlivé moduly pokrývají oblasti strategického řízení a koordinace, operativního řízení a výkonnosti, vnější komunikace, etiky a integrity a zaměstnanecké a sociální politiky. Je využitelná pro různé organizační úrovně státní správy i samosprávy. Je uživatelsky přívětivá a uživatel získává jednak okamžitou zpětnou vazbu, jednak návod pro generování návrhů opatření ke zlepšování. Metodika je inspirativní, protože kromě vlastního hodnocení představuje zároveň i dobré praktiky.\n Keywords: public policy; public service; good governance Available at various institutes of the ASCR

Higher teachers’ salaries: promises, promises, promises
Münich, Daniel; Smolka, V.
2018 - Czech
International comparisons show that Czech teachers’ pay, in relation to other tertiary educated workers, has long been among the lowest across the most economically developed countries. Based on the latest international comparisons published, from 2015, Czech teachers earned 56% of what other tertiary educated workers were earning, whereas the average across OECD countries was 83%. Mezinárodní srovnání ukazují, že platy českých učitelů, v relaci k ostatním vysokoškolsky vzdělaným pracovníkům, patří dlouhodobě k nejnižším mezi ekonomicky nejvyspělejšími zeměmi. Podle posledních publikovaných mezinárodních srovnání z roku 2015 tento podíl v České republice dosahoval 56 %, zatímco průměr zemí OECD byl 83 %.

Tourist interest in illicit zone of ice caves
Nováková, Eva; Kuda, František; Kubalíková, Lucie
2018 - English
Ledové sluje (Ice Caves) in the Podyjí National Park represents one of the most spectacular sites within the area. It consists of the large boulder field and several pseudokarst caverns on the north-western slope of the ridge that are very important from the ecological and geomorphological point of view. The access to the site is restricted for the visitors of National Park as there exists a risk of damage and disturbance of these unique phenomena; tourist can use the marked paths leading around the site, they can reach the top part of the ridge.\nCurrently, there are only several persons who have legal access to the site (employees of the National Park Administration and other researches with the permission issued by NP Administration). However, the installed sensor that counts the passages proved that the site is visited more frequently than it should be. The number of people who visit this site (situated within the first zone of National Park where there is no marked path and so the access is forbidden by decree) is quite alarming. Based on these findings, some proposals for the solution of this unfavourable situation are proposed and other possibilities how to avoid this undesirable phenomenon are discussed.\n Keywords: Podyji National Park; restricted area; passages monitoring Available in a digital repository NRGL

Generation of Intermittent Jet by Pulse-Modulated Synthetic Jets
Broučková, Zuzana
2018 - English
An axisymmetric air jet was excited using a pair of counter synthetic jets running in opposed direction. First, the control synthetic jets were measured alone. The driving signal was pulse modulated sinusoidal signal. After an adjustment, the primary axisymmetric jet was excited to the bifurcating mode, and its behavior was studied experimentally. For comparison purposes, a reference steady (unforced) jet from the same nozzle was also measured (Reynolds number was approximately 1300). The flow visualization and hot-wire anemometry techniques were used. Keywords: synthetic jet; pulse modulation; flow control Available at various institutes of the ASCR
