The efficient recovery and conversion of energy in oily sludge has great prospects. In this article, the main objective is to investigate the impact of the addition of CO2 during the pyrolysis of oily sludge on energy recovery and conversion by thermogravimetric analysis (TGA) and compare the effect with the traditional pyrolysis effect from the perspective of thermal conversion behavior, products composition, and kinetics analysis. The results of the experiment showed that in the CO2 atmosphere, the main weight loss temperature of oily sludge was mainly concentrated in the range of 300–500 °C, which is lower than the reaction temperature range of traditional pyrolysis. The yields of CO and H2 in the products have been greatly improved, and the highest proportion in the gas products can reach 19.29% and 22.38%, respectively. The Ea (activation energy) values of oily sludge were determined to be in the range of 40–120 kJ·mol−1 with the conversion between 0.2 and 0.8 via DAEM, KAS, Starink, and FWO methods, respectively, in which the FWO method has shown the strongest adaptability. The results of this study provide reference values for practical engineering applications. [ABSTRACT FROM AUTHOR]

A new algorithm for solving S. Geetha and K.P.K. Nair's proposed variant of the n-by-n bottleneck assignment problem is introduced. The procedure is based on the application of M.L. Balinski's signature method or dual simplex method to the assignment problem at each stage. Unlike Geetha and Nair's O(n5) algorithm, it is simpler, having a complexity of 'O m(m + n log n)' where m is the number of arcs.

Pathogenic microorganisms can impact the behavior and physiology of herbivores by direct or indirect means. This study demonstrated that yellow peach moth Conogethes punctiferalis larvae feeding on Penicillium -infected apples exhibited significantly longer body length and weight parameters compared to the control group. The sequencing of gut 16S rRNA showed a significant increase in the diversity and abundance of bacteria in the larvae feeding on Penicillium -infected apples. Additionally, transcriptomic sequencing of the larval gut indicated significant upregulation of genes related to digestion and cuticle formation after consuming Penicillium -infected apples. Furthermore, enzyme activity assays revealed notable changes in the trypsin and lipase activity. Consequently, these alterations in gut microbiota structure, diversity, and gene expression levels may underlie the observed growth and developmental variations in C. punctiferalis larvae mediated by pathogenic microorganisms. This study holds theoretical significance for a deeper understanding of the tripartite interaction among microorganisms, insects, and plants as well as for the development of novel pest control measures based on gut microbiota.

Microneedle percutaneous immunization is achieved by puncturing the stratum corneum of the skin with microneedles so that the vaccine is efficiently recognized by antigen-presenting cells to induce a specific immune response. Due to the advantages of efficient induction of immune response, low pain and easy storage, transdermal immunization by microneedles has been widely used for immunization of various vaccines in recent years. This review summarizes the materials of microneedles, application for transcutaneous immunization, as well as the challenges that need to be addressed.

The results of the experiment showed that in the CO 2 atmosphere, the main weight loss temperature of oily sludge was mainly concentrated in the range of 300-500 °C, which is lower than the reaction temperature range of traditional pyrolysis. The yields of CO and H 2 in the products have been greatly improved, and the highest proportion in the gas products can reach 19.29% and 22.38%, respectively. The E a (activation energy) values of oily sludge were determined to be in the range of 40-120 kJ·mol -1 with the conversion between 0.2 and 0.8 via DAEM, KAS, Starink, and FWO methods, respectively, in which the FWO method has shown the strongest adaptability.
