Key differentiators affecting costs between these two asphalt concrete types are identified, including fuel consumption during production, material expenses, and overall mixture costs. Methodologies encompassing technical specifications and experimental investigations are applied, employing analytical and comparative techniques.A comprehensive technical and economic evaluation of porous and crushed-mastic asphalt concrete is conducted, factoring in identified cost variables. To determine comparative economic efficiency, industry-standard resource consumption metrics, material utilization norms, recommendations, and laboratory analyses are incorporated. Estimates are derived using aggregated data and the price calculator provided by the State Enterprise \"DerzhdorNDI SE,\" referencing June 2023 data from Ukraine's infrastructure restoration and development services. Analysis reveals that, when assessing material, production, and installation costs exclusively, porous asphalt concrete demonstrates superior economic advantages. Furthermore, the study establishes that the implementation of porous asphalt concrete has the potential to reduce road accidents substantially. This reduction in accidents yields significant economic benefits by mitigating overall socio-economic losses stemming from traffic incidents, thus counterbalancing expenses associated with specific challenges linked to winter maintenance and the cleaning of asphalt pores.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135040706","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 bioplastics are environmentally friendly compared to plastics that are made from fossil fuels. But this is not always the case - a lot depends on how bioplastic is produced and disposed of. The bioplastics industry is young—accounting for only 1% of global plastics production in 2019. Standardization of raw material sources, types of plastic, or labeling of what is biodegradable or compostable is poorly developed. This often confuses consumers because not everything made from plants is biodegradable. However, growing awareness of the dangers of overuse of plastics and increased government regulation of plastic waste have led to a surge of interest and investment in bioplastics, an industry expected to grow 10-14% in the next few years. It is possible that this will partially help solve one of the most serious environmental problems in the world: plastic pollution. Marine plastic pollution is a growing global problem. The most striking example is the Great Pacific Garbage Patch. According to the EPA (U.S. Environmental Protection Agency), of the approximately 36 million tons of plastic produced annually in the United States, less than 1% is recycled. Globally, only about 9% of plastic waste is recycled. About 11 million tons of plastic waste are dumped into the world's oceans every year. Even more comes from land-based sources, where plastic slowly breaks down into smaller and smaller particles. According to some estimates, there are up to 51 trillion microplastic particles floating in our oceans. Scientists estimate that the average adult ingests approximately 883 microplastic particles every day, which accumulate in our body tissues. Ingestion of plastic by marine and terrestrial animals can have extremely adverse effects on their health, including death.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135081375","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 building sector accounts for about 40% of the energy saving potential, therefore reduction of energy losses is the best way to reduce energy consumption of buildings. To calculate the heat loss from the building envelope, it is necessary to know the thermal conductivity coefficient (λ) of each construction element. Currently developed methods of λ determination are entirely based on the laboratory test using the stationary regime. For more realistic results, it is necessary to take into account the daily variability of temperature and non-stationary thermal conductivity processes. Solving the non-stationary thermal conductivity tasks are associated with the significant difficulties due to the application of the relatively complex mathematical equations. Usually, the theory of non-stationary thermal conductivity refers to the method of separation of variables or the so-called Laplace Transform, which requires the use of operational counting methods. The article presents an innovative method for determining the coefficient of thermal conductivity (λ) of each construction element in the non-stationary temperature regime, which enables determination of heat losses from the building envelope in real environment using the precise definition of thermal flow velocity.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084943","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}

Of interest is the phenotype of type 2 diabetes mellitus (T2DM) without obesity, which may be associated with impaired levels of counter-insulin hormones. 87 patients with T2DM (age 40-78, females/males – 41/46) were examined. Anthropometric parameters and body composition were assessed by the bioelectrical impedance. OC, cortisol, dehydroepiandrosterone sulfate (DHEA-S) blood levels, and the ratio of cortisol/DHEA-S as indicator of the body stress resistance, were measured. Patients were divided into 4 quartiles, depending on the serum OC level, that were significantly different from each other. Cortisol/DHEA-S ratio was significantly different between the first (lowest OC level) and the fourth quartiles (highest OC level) and between the second, third and fourth quartiles. Visceral fat level was the highest in the first OC quartile, and the lowest in the fourth quartile. When comparing the percentage of total fat between quartiles, no significant difference was found, which may indicate the importance of visceral fat in the formation of metabolic phenotypic changes in the presence of T2DM. The lowest serum OC level was observed in patients with the greatest intensity of chronic endogenous stress, which is manifested by glucocorticoid function increase according to the cortisol/DHEA-S ratio. It is assumed, that local hypercorticism is the cause of stem cell differentiation into adipocytes, which leads to the formation of a diabetes phenotype with the accumulation of visceral fat without general obesity and the slowing of osteosynthesis with a decrease of the OC level.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084944","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}

Roadside areas accumulate a large amount of pollutants which leads to changes in soil properties and comprehensive degradation of landscapes. Together with the road runoff, pollutants enter the lakes and the rivers and cause significant damage to aquatic flora and fauna. During the operation of highways, a large amount of exhaust gases, oil products, heavy metals, and dust enters the natural environment. Currently, in Ukraine, most studies are aimed at reducing the negative impact of exhaust gases on the atmosphere, oil pollution of soils and the aquatic environment. Unlike in the European countries, the research on the formation of microparticles which, together with dust and surface runoff contaminate soils, surface and groundwater of roadside areas has not been conducted at all. This paper analyzes the European research experience on the negative impact of microparticles on the environment.

An urgent task is to improve the performance of these coatings in order to extend their service life and minimize the frequency of repair work, which, especially on bridges, cause great difficulties and require significant additional costs. There is no doubt that when using epoxy asphalt concrete as a thin-layer pavement, we get a strong, flexible surface, resistant to cracking and rutting. However, this is not yet a sufficiently researched material for its possible wide application, as it requires a special approach to the establishment of the composition and technology of its preparation. The application of a thin-layer coating on an orthotropic or reinforced concrete slab of the carriageway of the bridge made of epoxy asphalt-concrete mixture requires special attention in establishing the optimal selection of its composition and cooking technology. Particular attention should be paid to ensure the required viability of the epoxy asphalt mixture, the use of the desired hardener, which affects its properties, determining the required number of thermosetting modifiers, determining the duration of curing depending on temperature.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084942","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}
