In fact, the addition of the coal pyrolytic extracts can adjust the molecular structure of the blending pitch, and the coal pyrolytic extracts can promote the generation of the MCMBs during the co-polycondensation process. The microstructure and morphology of the derived MCMBs were determined by an optical microscope, scanning electron microscope, X-ray diffraction, Raman spectrum, and laser particle size analyzer. materials, and coal pyrolytic extracts were used as additive to synthesize the MCMBs. For a detailed analysis of the synergistic effects of the generation of MCMBs, a high-temperature coal tar pitch was used as raw. The physicochemical property of the raw materials plays a key role in the quality of MCMBs. Mesocarbon microbeads (MCMBs) are a kind of engineering and functional artificial carbon materials generally prepared by the polymerization of polycyclic aromatic hydrocarbons. As much as 12,200 t of contaminants were removed from the soil. Surprisingly, the overall groundwater contamination amounted to 232.86 t of contaminants as non-aqueous phase liquids, and 6872.9 kg of dissolved contaminants. The post-remediation monitoring showed that all the contaminant levels were below the limit. At the start of the remediation process, the contaminant levels exceeded the limits by the Czech Environmental Inspectorate several times. The locality is characteristic of a high horizontal and vertical grain-size heterogeneity of gravel-sand, which led to a varying filtration coefficient affecting the capacities of pumped groundwater quantity during the remediation. In detail, the article describes the removal of the contaminated groundwater and compares the quality of the pumped and inflowing water before and after the remediation. To excavate the soil, it is necessary to reduce the contaminated groundwater level inside the sealing walls and thus create conditions for the extraction of contaminated soils using standard machinery. Next, all contaminated groundwater may be pumped off upon the construction of sealing walls to control groundwater flows. Its advantage is the absolute qualitative and quantitative control over the contaminated soil with the possibility of precise segmentation into contaminated and non-contaminated soils. of removing contaminants both from soil and groundwater. The aim of the article is to point out the advantages of ex situ soil remediation via the excavation of the contaminated geological environment combined with thermal desorption, a method. The article describes the remediation of contaminated groundwater during the ex situ remediation of coal tar contamination following the closure of a coking plant in the Moravian–Silesian Region (Czech Republic). Conclusão: Esse momento possibilita (re) pensar a experiência de velórios com distanciamento que pode ocasionar transformações no cuidado, empoderamento, compaixão e humanização das pessoas envolvidas. O familiar vivencia conflitos e dilemas éticos frente ao desespero e frustração por estar impossibilitado da despedida e como estratégias de enfrentamento, diálogo cuidado e respeito aos princípios da bioética. Resultados: Procedeu-se ao estabelecimento de estratégias de enfrentamento ao luto sem despedidas vivenciados pelo familiar na perda de seu ente por COVID-19. Realizou-se busca nas bases de dados Bireme, Lilacs e Scielo e em documentos oficiais. Método: Estudo de revisão narrativa da literatura. Objetivo: Apresentar estratégias de enfrentamento ao luto sem despedidas para o familiares frente aos conflitos e dilemas éticos vivenciados na perda do ente por COVID-19. Introdução: O luto é individual e singular, desenvolve conforme características do enlutado e circunstâncias da morte.
