The current investigation focuses on the copyrolysis of L. (a nonedible oilseed, also known as Nahar) and polyethyelene terephthalate (PET) plastic waste to gain insights into the composition of pyrolysates and the thermal decomposition of complex and mixed feedstocks. The physicochemical properties of the feedstocks were studied through thermogravimetric analysis at a heating rate of 15 °C min, bomb calorimetry, and proximate/ultimate analysis.

Urbanization and population growth in India have quickened, leading to an annual generation of around 62 million tonnes of municipal solid waste (MSW). Improper management of organic waste presents a major environmental problem due to air and water pollution, soil contamination and greenhouse gas production. This research aims to develop refuse-derived fuel (RDF) as a viable option, converting waste into a high-calorific energy carrier for industrial use.

Ultimate and proximate levels of analysis offer synergistic explanations can improve the search for causes of disease and their cures. Here we review how several principles of evolutionary biology such as historical contingencies, mismatches, trade-offs, sexual selection and genomic conflict are applied to problems in medicine and psychiatry. The application of evolutionary principles to many other domains of medicine, among them mental disorders, have not received the same reception from preclinical and clinical researchers.

Wild-caught fish are an important subsistence food source in remote northern regions, but they can also be a source of exposure to mercury (Hg), which has known health hazards. We investigated factors and mechanisms that control variability of Hg concentrations in Lake Whitefish (Coregonus clupeaformis) among remote subarctic lakes in Northwest Territories, Canada. Integrating variables that reflect fish ecology, in-lake conditions, and catchment attributes, we aimed to not only determine factors that best explain among-lake variability of fish Hg, but also to provide a whole-ecosystem understanding of interactions that drive among-lake variability of fish Hg.

Proximate analysis, ultimate analysis, Fourier transform infrared spectrometry (FTIR), thermogravimetric analysis (TG-DTG) and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) results were compared to explore the influence of the thermal dissolution process on the pyrolysis for PLC and ISP. Results showed that the thermal dissolution process mainly dissolved some light components of low-rank coal, and more phenols, aldehydes, esters and ethers were found in the SP, indicating that low-carbon alcohols can break the ether bridge bond in coal and generate oxygen-containing organic compounds (OCOCs).
