The problem of high energy consumption concerns every treatment plant using aerobic activated sludge, hence the constant attempts to introduce possibly intelligent aeration control techniques. In this study, a short-term (hourly) forecast of oxygen concentration in the aeration chamber was calculated under the conditions of changing values of wastewater flow and pollutant concentrations as well as active aeration control according to an unchanging algorithm. Artificial neural networks were used to calculate the forecast. It is shown that an accurate prediction can be obtained by using different sets of input data but depending on what data we choose, the neural network required to obtain a good result has a more or less complex structure. The resulting prediction can be applied as part of a system for detecting abnormal situations and for preventing excessive energy consumption through unnecessary over-oxygenation of activated sludge.","PeriodicalId":54121,"journal":{"name":"Civil and Environmental Engineering Reports","volume":"32 1","pages":"428 - 439"},"PeriodicalIF":0.7,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44984219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the newly restored Poland the most pressing problem was the improvement of the housing conditions of the population. The military, who contributed the most to the reinstating of independence held special privilege with the state officials. Therefore, the problem of their quartering was resolved with utmost preference. After an unsuccessful period of trial and error with traditional and light timber frame construction the government addressed this problem systemically establishing the Military Accommodations Fund with a dedicated budget for creating typified, repeatable solutions. The MAF commissioned specific designers, held open as well as limited competitions and hired a cadre of architects and engineers to come up with designs that could rapidly and cost effectively replenish the housing base with functional, hygienic solutions. Because the MAF was well funded, the most prominent polish modernist architects readily cooperated with the organization making Polish interwar architectura militaris an engine of modernization.","PeriodicalId":54121,"journal":{"name":"Civil and Environmental Engineering Reports","volume":"32 1","pages":"210 - 229"},"PeriodicalIF":0.7,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43103616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zinc (Zn), copper (Cu), nickel (Ni), and lead (Pb)were the metals examined. Soil analysis also was carried out for the same elements. The tissues and bones of the fishes were separated before further analysis was made. Drying process technique was used to determine the moisture content for all samples at 80 °C for 24 hours. Water content ranged between 70 & 77%. Triplicate samples were evaluated by using Atomic Absorption Spectrophotometer (AAS) to find out heavy metals concentration. Oven and Teflon beakers were used to fully digest all solid samples at 120 oC for 3 hours. Highest readings of Zn, Ni and Pb were found in the fish bone for the samples collected from both mentioned locations. However, different pattern was noticed for Cu where higher values were found in the tissues for the same samples. Values of Pb in the tissues were higher than the acceptable value in edible fish by Food and Agriculture Organization (FAO); 1 ppm and Malaysian Food Act (MFR) & World Health Organization (WHO); 2 ppm, whereas values of Cu, Zn were in the acceptable range set by the same organizations. No values recommended for Ni by MFR. In general heavy metals in the bones and tissues from both locations can be sorted in descending order as follows; Pb>Zn>Cu>Ni. Soil samples collected from both locations showed different pattern where high concentration was found for Zn followed by Pb then Cu and Ni. Moreover analysis for soil samples collected from Paka River showed higher content for all elements compared to Kijal. More investigation is needed to clarify whether this contamination is solely from industry or due to geology of the area.","PeriodicalId":54121,"journal":{"name":"Civil and Environmental Engineering Reports","volume":"32 1","pages":"270 - 281"},"PeriodicalIF":0.7,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43404798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It remains in a close and inseparable relationship with architectural design. Contemporary technologies in construction are constantly subject to improvements, streamlining, changes aimed at increasing all kinds of efficiency (cost, thermal efficiency, labor input, etc.). One of today’s widely discussed determinants of changes in the way buildings are designed and constructed is environmental issue. An awareness of environmental degradation and climate change and their consequences prompts the search for increasingly sustainable solutions. This paper summarizes the research on prefabricated solutions and their implementation, especially in single-family residential architecture. This article presents pre-design, design, and post-design experiences related to planning and realization of single-family houses with prefabricated wall technology made of light expanded clay concrete. The authors implemented comparative qualitative and quantitative research through case studies, the method also uses experiences from their own research by design practice. The advantages and disadvantages of prefabrication in the selected technology are presented. The authors attempt to answer the question of whether the individual architectural design approach is reflected in the relevant environmental considerations, including, first, those related to the mitigation of climate change and adaptation to its consequences, and to what extent the discussed technology fits into the assumptions of climate and environmentally responsible design.","PeriodicalId":54121,"journal":{"name":"Civil and Environmental Engineering Reports","volume":"32 1","pages":"323 - 344"},"PeriodicalIF":0.7,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42640416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most studies concerning microplastics are focused on water bodies, but it is considered that sediments and sands from the beaches may to be a long-term sink for microplastics. High concentrations of microplastics have been found in sand beach in Europe and all over the world. In the present studies samples of beach sand originating from three beaches of recreational reservoirs in Southern Poland (Silesian Voivodship) were analysed. Preliminary screening tests were done to evaluate the degree of microplastics pollution of the selected sandy beaches. Samples were taken once from three places on the beaches of each reservoir. Beach sections parallel to the waterline were selected at each study at the swash zone – about 1 m above the waterline. Previously, no studies were done on the presence of microplastics in these beaches. The samples taken from the beach were homogenized and mixed with saturated NaCl solutions, after separation of microplastics the pollutants were counted under optical microscope (under magnification 40 -100 x). It was found that in all three places the microplastics occurred in the beach sand samples. The most contaminated samples originated from Lisiniec recreation park (Adriatyk) which contained 340 ± 222 particles per kg/d.m. The most abundant fractions in the examined samples were fibres and fragments, the less abundant ones were granules. It can be concluded that recreational reservoirs beaches can be significantly contaminated by microplastics particles, but simultaneously the concentrations of these micropollutants can vary a lot between the individual places.","PeriodicalId":54121,"journal":{"name":"Civil and Environmental Engineering Reports","volume":"32 1","pages":"230 - 241"},"PeriodicalIF":0.7,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46726597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
