Abstract The article presents the research of thermal comfort based on the Fanger model. The research was conducted in three educational rooms. The study involved 98 people whose age is between 19 and 23 years old. The study consisted in measuring the parameters of the thermal environment. During the research, students completed surveys regarding the thermal sensation. On the basis of the research, the predicted mean vote PMV score and the predicted percentage of dissatisfied PPDs were determined. This made it possible to compare the assessment of respondents with those indicated according to the standard, which showed that the Fanger model does not reflect the results of the respondents. The best solution will be to modify the Fanger model.

Abstract Currently, a significant problem of water and sewage management is the presence of human hormones, especially estrogens and progestagens, consumed by women in contraceptives and then excreted from the body. While other drugs are used by a small part of the population and rather sporadically, hormonal contraception is used by a large number of women, which contributes to their high concentration in sewage. Even relatively low estrogen concentrations (compared to other drugs) can have harmful effects on the body, disturbing the hormonal balance and leading to various endocrine disorders. In this paper the types of individual estrogen groups were characterized. Next, different methods of their removal from wastewater were presented. The parameters of estrogen removal efficiency depend on which parameters. Next, the effectiveness of each method was compared, also taking into account economic aspects. The work was summarized with appropriate conclusions.

Abstract The article discusses the methodological principles of typology and design of architectural environment’s objects with the analysis of its system-structural foundations. According to them, hierarchical levels of formation and stages of environmental systems and objects’ design are revealed with some examples of author’s designs. The research is based on systemic and environmental approaches that make it possible to view the architectural environment’s objects as hierarchically subordinate.

Abstract The paper presents concentrations of pharmaceuticals in surface water and sewage. Special attention was paid to the content of estrogens in municipal sewage and the method of their disposal. Concentrations of various pharmaceuticals in raw and treated wastewater were compared and the pharmaceuticals in different countries and waters were presented in tables. The most frequently identified drugs in sewage are sex hormones (etradiol, ester, ethinylestradiol, 17 β-estradiol) and the antiepileptic drug Carbamazepine. These drugs are difficult to remove from water and therefore appropriate treatment processes are used, such as: adsorption on active carbon, UV irradiation, etc. Contamination of water with pharmaceuticals has a negative impact on the development of aquatic organisms and can lead to serious human health problems.

Abstract The paper is focused on diagnostics of reinforced concrete structure of the tribune of Závodisko Bratislava. The structure was realized by a combination of monolithic and prefabricated concrete elements as well as steel load-bearing elements. The complex state of the rough construction was evaluated, including the verification survey of the foundation of the construction. Non-destructive and destructive methods were used. Based on the results of the diagnostics and recalculation, it was decided to further progress the finish of the tribune.

Abstract On the basis of use of modern research methods, the requirements for designing new types of teaching and educational complexes “Kindergarten – Primary School” were determined. It was established that the form and methods of kindergarten education have a certain analogy with the education in the first grades of primary school, which is one of the factors of feasibility of blocking and cooperation of the senior kindergarten groups with the elementary grades of general education schools and the formation of teaching and educational complexes on this basis, which enables receptiveness to demographic fluctuations and, if necessary, change of the function of kindergarten to the function of primary school, and vice versa – the flexibility and multivariance of the teaching environment is one of main conceptual provisions in building of network and typology of educational facilities at the present stage, on the basis of which the structural elements of school network in massive restrained urban development are formed.

Abstract Practical use of a new type of combustion waste such as an agricultural biomass fly ash in the building materials requires an assessment of its performance. The paper presents the investigation results on the influence of cement substitution (5% and 30%) by this ash on the cement and polymer-cement composites resistance to carbonation. The composites resistance was assessed on the basis of carbonation process over time (up to 360 days) using the phenolphthalein method. It was found that fly ash from agricultural biomass increases the susceptibility to carbonation of polymer-cement composites to a lesser extent than cement composites compared to composites containing siliceous coal fly ash.

Abstract Sewage sludge is a by-product of wastewater treatment processes. However, it has high fertilising and soil-forming properties, but it cannot always be used for this purpose. The two main criteria limiting their natural use are heavy metals and parasite eggs. Sewage sludge taken from the Daleszyce wastewater treatment plant has been analysed for heavy metals. For this purpose a space analysis was performed to divide the total metal content into four mobility fractions. The mobility issue determines the ability of an element, or one of its forms, to move in the environment. The studies were performed using a four-stage BCR procedure. The results were analyzed and compared to the limits applicable in Poland for sewage sludge intended for environmental use.

Abstract Good quality bitumen used in the production of bitumen-aggregate mixtures is a binder with high stiffness and elasticity at high operating temperatures occurring in summer and adequate flexibility during exposure to sub-zero temperatures. Currently, one of the best technological solutions to improve the viscoelasticity of bitumen and the resistance to ageing is their modification with various types of additives. The paper presents the results of penetration tests as a function of temperature, softening point (ring and ball method) and strain energy at various temperatures of road bitumen modified with SBS (styrene-butadiene-styrene) copolymer, crumb rubber and simultaneous bitumen modification with SBS copolymer and crumb rubber. The obtained results allowed to assess temperature sensitivity, resistance to changes in selected technical properties of the tested binders as a result of technological ageing process with RTFOT (Roler Thin Film Oven Tester) method and to evaluate changes in their technical properties in relation to the 50/70 base bitumen. Multivariate analysis of variance (MANOVA) was used to analyse the impact of the modification type on the test results of technical properties (significance of the impact of the considered factors on the level of technical properties).
用于生产沥青-骨料混合料的优质沥青是一种粘合剂，在夏季高温下具有高刚度和弹性，在零下温度下具有足够的柔韧性。目前，提高沥青粘弹性和抗老化性能的最佳技术解决方案之一是使用各种添加剂对沥青进行改性。本文介绍了SBS(苯乙烯-丁二烯-苯乙烯)共聚物和橡胶屑改性沥青以及SBS共聚物和橡胶屑改性沥青在不同温度下的渗透试验结果与温度、软化点(环球法)和应变能的函数关系。使用RTFOT(辊式薄膜烘箱测试仪)方法，获得的结果可以评估被测粘合剂的温度敏感性、对技术老化过程中所选技术性能变化的耐受性，并评估与50/70基础沥青相关的技术性能变化。采用多变量方差分析(Multivariate analysis of variance, MANOVA)分析修改类型对技术性能测试结果的影响(所考虑因素对技术性能水平影响的显著性)。

Abstract The research was conducted on samples of water in Kielce from two intakes: Białogon and Zagnańsk. The results of selected indicators for these waters were presented, among others, the most important ones influencing its chemical stability i.e. calcium or magnesium. Then, using the PHREEQC program, stability indices were calculated for water in Kielce from the two shots in question. In the next stage, the correctness of the water test method was checked by means of a program through the ionic balance of the water and comparison of pH of the water determined with the value determined by calculation. For the above mentioned activities, tables and calculations were prepared on the basis of which appropriate conclusions were made.
