High temperature testing of cement mortar containing bottom ash (BA) generated by municipal solid waste incineration (MSWI) as partial replacement of natural aggregate is presented in the paper. The ...measurements of mechanical properties, bulk density, matrix density, and total open porosity are performed on samples exposed to the temperatures of 20°C to 1000°C. TGA analysis is performed as well. Finally, the studied samples are analyzed by IR spectroscopy in order to evaluate TGA data. The obtained results indicate a comparable performance of the mortar modified by BA with the reference material.
Education means: learning, teaching or the process of acquiring skills or behavior modification through various exercises. Traditionally, medical education meant the oral, practical and more passive ...transferring of knowledge and skills from the educators to students and health professionals. Today the importance of focus on educational quality, particularly in the professions operating in the services required by people is agreed by all involved. The higher educational system shoulders some critical responsibilities in the economic, social, cultural and educational development and growth in the communities. In countries that are in transition it is in charge of educating professional human workforce in every field and if the education is optimal in terms of quality, it is capable of carrying out its responsibilities. It is reason why there is the necessity behind discovering some strategies to uplift the quality of education, especially at university level.. By increasing the courses and establishing universities and higher education centers, the countries around the world have generated more opportunities for learning, especially using modern information technologies. Regarding to evaluating different educational services quality, one of the most important measures should be the way to develop programs to promote quality and also due to the shortage of resources, evaluating the services quality enables the management to allocate the limited financial resources for realization whole educational process. Advances in medicine in recent decades are in significant correlation with the advances in the new models and concepts of medical education supported by information technologies. Modern information technologies have enabled faster, more reliable and comprehensive data collection. These technologies have started to create a large number of irrelevant information, which represents a limiting factor and a real growing gap, between the medical knowledge on one hand, and the ability of students and physicians to follow its growth on the other. Furthermore, in our environment, the term technology is generally reserved for its technical component. This terminology essentially means not only the purchase of the computer and related equipment, but also the technological foresight and technological progress, which are defined as specific combination of fundamental scientific, research and development work that gives a concrete result. The quality of the teaching-learning process at the universities in former Yugoslav countries and abroad, depends mainly of infrastructure that includes an optimal teaching space, personnel and equipment, in accordance with existing standards and norms at the cantonal or entity level, which are required to implement adequately the educational curriculum for students from first to sixth year by Bologna studying concept. For all of this it is necessary to ensure adequate funding. Technologies (medical and information, including communications) have a special role and value in ensuring the quality of medical education at universities and their organizational units (faculties). "Splitska inicijativa" project, which started 6 years ago as simple intention to exchange experiences of application new model of education, based on: Bologna studying concept, and other types of under and postgraduate education, was good idea to improve also theory and practice of it within Family medicine as academic and scientific discipline. This year scope of our scientific meeting held in Sarajevo on 24th and 25th March 2017, was quality assessment of theoretical and practical education and, also, evaluation of knowledge by students exams (a-y).
Mor, který priel ve 40. letech 14. století, predznamenal dlouhé období periodicky se vracejících smrtících epidemií. Nebezpecí se nevyhýbalo nikomu, cerná smrt" pravidelne postihovala bohatá ...obchodní centra v Itálii stejne jako spore zalidnené regiony Skandinávie. Teprve na pocátku 18. století nemoc z Evropy zmizela stejne záhadne, jako se o ctyri století dríve objevila. Morová nákaza byla nejen zdrojem paniky, drastických sanitárních opatrení ci morálního sebezpytování, ale predstavovala i sloitý lékarský problém. Od vrcholného stredoveku do období osvícenství vzniklo na toto téma nescetne traktátu. Tato publikace se zabývá postupnými promenami názoru na mor mezi lékari raného novoveku v nekolika oblastech. Predne se venuje vývoji dobové lékarské literatury, zkoumá vliv modernity ci naopak tradice a zpusob, jím spolu ruzní autori vedli ucené spory. V následující cásti na základe výberu pramenu z rady oblastí Evropy sleduje hlavní teorie o puvodu moru vcetne predstav o zkaení vzduchu, názoru na nakalivost nemoci ci nauky o moru prenáeném lidskými smysly. Dále popisuje, co doporucovali renesancní a barokní lékari svým klientum, kterí se chteli chránit pred nákazou. lo o iroké spektrum preventivních opatrení pocínaje karanténou ci útekem z nakaené oblasti pres dodrování vhodné diety a po uívání ruzných druhu amuletu. Poslední cást knihy popisuje rane novovekou lécbu morem nakaených pacientu, a to jak podáváním léku ci tzv. chirurgickými" metodami (poutením krve ci otvíráním morových bubonu).
Salt binding in porous materials is commonly described by ion binding isotherms which
express the equilibrium relation between the amount of free ions in the solution and
the amount of bound ions on ...the pore walls in the porous medium. In this article,
chloride binding isotherms of several different types of building materials, among
them cement paste, ceramic brick, mineral wool, and calcium silicate, are determined
using the adsorption method. The experiments are performed on small but not crushed
specimens so that the effect of the porous structure is maintained. Also, the
experiment with crushed samples as in the original adsorption procedure is done for
the sake of comparison, and the differences are analyzed. It is concluded that the
chloride binding capacity of building materials may depend on the size of the sample.
The time domain reflectometry (TDR) method is commonly used for the measurement of
moisture content in soil science. In this study, the method is employed for the
measurement of moisture profiles in ...building materials. The practical applications
of the method are presented on an example of water penetration into cellular
concrete (aerated autoclaved concrete) samples. The measured results are then used
for the determination of moisture diffusivity as a function of moisture content.
A measuring system for determination of temperature, moisture, relative humidity, capillary pressure and salinity profiles in building envelopes is presented in the paper. The system makes it ...possible to analyze the hygrothermal performance of either particular materials or the whole building envelopes in the conditions of difference climate. Both the spatial dimensions of the specimens and the applied exterior and interior climatic data are chosen to be as close as possible to the conditions in the particular building site, so that the system can simulate the hygrothermal processes in the envelopes in quite a realistic way. A sophisticated technology for the determination of moisture, relative humidity, capillary pressure, temperature and salinity in the analyzed specimens based on the application of timedomain reflectometry, mini-tensiometry and mini-hygrometry is employed, which guarantees obtaining reliable data for validation of sophisticated computational models.
The basic thermal and hygric parameters of two different types of carbon-fiber-reinforced cement composites are analyzed in this article. The thermal conductivity, specific heat capacity, moisture ...diffusivity, and water vapor diffusion resistance factor are determined as functions of thermal load and tensile load applied before the measurement as well as of the combination of both types of load. The tensile load up to failure is found to be not a very significant factor for all material properties analyzed except for the moisture diffusivity. On the other hand, the thermal load is observed to result already at 600 C in considerable changes in all investigated thermal and hygric properties except for the specific heat capacity. The combinations of thermal and tensile loads lead to similar results as the effect of the thermal load alone so that the domination of the thermal load is apparent. This is supposed to be due to the positive effect of randomly distributed carbon fibers that can reduce the damage of the pore structure by the tensile stress. The resistance of the materials studied to high temperatures expressed by the change of hygric and thermal properties after thermal load is found to be positively affected by the application of the high alumina cement and in the case of the Portland cement-based composite also by using the autoclaving procedure in the production process.
An interior thermal insulation system based on hydrophilic mineral wool is presented in this paper. Basic thermal and hygric parameters of the applied materials are given. The design and development ...of the thermal insulation system including its verification in semiscale experiments are described. Finally, an example of the application of the designed system in the reconstruction of a historical building in Prague is shown, and the results of in situ experiments are presented.
