On the basis of the price volatility index of twelve contracts concluded in 2016 by the Directorate of National Roads and Motorways (DDKiA), there was little variation in the average construction prices of 1 km of technical class S expressways on flat and undulating terrain, over a large area of Poland, above Wrocław and Lublin towards the north. However, also for the expressway, but in mountainous terrain in Małopolska, between Lubień and Chabówka, on three sections of S7, together with a length of 15.8 km, the coefficient of variation in unit prices was very large (5.7 times greater than in the flat and corrugated areas mentioned above). Among the reasons for this high price volatility, it was pointed out that it was necessary to adapt to difficult mountain conditions through the use of specialized technical solutions, costly in implementation and other on almost every of these sections. Necessary were, among others over a 2-kilometer tunnel (many times more expensive than the other sections of the route), intensive reinforcement of escarpments with ground nails (with a total length of over 350 km) and foundation of embankments on gravel columns, as well as construction of numerous flyovers, viaducts and bridges with a total length of 5,752 km. Attention was also paid to the necessity of taking into account the proportion of the tunnel’s length to the length of the remaining road section, as this is a condition of correct expenditure analysis.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44830141","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}

During such stages as min-ing, transporting, treatment, storing and processingof coal, a large number of small products are formed, such as screenings, spills, sludges, etc. Such products are not usedand significantly pollute the environment. Meanwhile, after agglomeration, they can eas-ily be used for the production of thermalenergy. Of all the known agglomeration meth-ods, briquetting is most suitable. The technology of obtaining flammable briquettesbased on coal is developed. A technology has also been developed to produce fuel bri-quettes from coal slurries and paper waste.The use of coal slurries and paper waste as binder materials makes it possible to obtain a fuel pellet that is simple in production andcomposition and at the same time allows to utilize coal and paper wastes. The technolo-gy of obtaining fuel extrudates (briquettes)from wood and shale wastes, as well as wood, shale waste and sludge was developed. Thus, technologies have been developed toproduce fuel briquettes from various types of low-demand carbon-containing materi-als for domestic use.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46185377","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}

The Czech Army professionals are expected to have frequent presence in apolluted environment and regular exposure to air with increased concentration of airborne pollutants. The report evaluates the presenceof ultra-fine particles (in the range of about 7.6–299.6 nm) in rooms often used by soldiers during their working hours whenthey are not deployed. The purpose is to assess whether the presence of troops in these workplaces is safe and does not pose a riskof adverse health effects in itself. Testing took place in three military rooms (classroom 1, classroom 2 and exercise flight simulatorroom). Seven samples of air were analysed in time by the scanning mobility particle sizer in succession. Mean particle concentrationswere found at 1.79×104, 7.53×103 and 8.39×103 N·cm-3 for the classroom 1, classroom 2 and exercise flight simulator room.Conclusions of the research have shown that particle concentrations in the places of the Czech Army can reach values that borderthe immission limits stated by the World Health Organisation.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48042967","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}
