- The generation of bioenergy and bioproducts from biowaste streams has piqued global interest in achieving a cutting-edge circular economy. The integration of biowaste into the cutting-edge circular economy has the potential to significantly increase the production of sustainable bioproducts and bioenergy. The potential for advanced forms and innovations to transform complicated, natural-rich biowastes into a variety of bioproducts and bioenergy with an advanced circular economy has been demonstrated in this article. It is described to emphasise the critical nature of research into improving biowaste conversion into circular economies and the impact that bioeconomy has on various societal sectors. The present study examined how microbial profiles have transformed treasured bioenergy and bioproducts aspirations into mechanical bioproducts marvels discovered through cutting-edge microbial analyses of biowaste. Additionally, the article discussed contemporary experiences with the developing circular economy of biowaste as a resource for numerous bioproducts and bioenergy businesses, as well as the emanant biowaste biorefinery methods that could be used to evaluate industrial-scale maintainable financial models for updated bioproducts and other generation-related issues.

- Selective vulnerability is an enigmatic feature of neurodegenerative diseases (NDs), whereby a widely expressed protein causes lesions in specific cell types and brain regions. Using the RiboTag method in mice, translational responses of five neural subtypes to acquired prion disease (PrD) were measured. Pre-onset and disease onset timepoints were chosen based on longitudinal electroencephalography (EEG) that revealed a gradual increase in theta power between 10- and 18-weeks after prion injection, resembling a clinical feature of human PrD. At disease onset, marked by significantly increased theta power and histopathological lesions, mice had pronounced translatome changes in all five cell types despite appearing normal. Remarkably, at a pre-onset stage, prior to EEG and neuropathological changes, we found that 1) translatomes of astrocytes indicated reduced synthesis of ribosomal and mitochondrial components, 2) glutamatergic neurons showed increased expression of cytoskeletal genes, and 3) GABAergic neurons revealed reduced expression of circadian rhythm genes. These data demonstrate that early translatome responses to neurodegeneration emerge prior to conventional markers of disease and are cell type-specific. Therapeutic strategies may need to target multiple pathways in specific populations of cells, early in disease.

Evaluation of test methods and face-sheet thickness effects in damage tolerance assessment of composite sandwich plates

- Composite sandwich materials provide high bending performance-to-weight ratios. However, these materials are vulnerable to impact damages which can drastically reduce their load-bearing capability. Presently there is a lack of standardised test methods for impact assessment. This study compares three different test methods for impact assessment; single skin compression after impact (CAI-SS), sandwich compression after impact (CAI-SW) and four-point bending-after-impact (BAI). The CAI-SS test method shows high compressive strength and strain at failure and the tesr is relatively easy to evaluate. For finite size plates with significant impact damage, the CAI-SS test method is recommended for post impact strength assessment. For large sandwich panels with relatively small impact damages the CAI-SW test method could be more relevant since it includes effects of panel asymmetry generated from the impact damage. The BAI test method may be recommended as an alternative to CAI but quite long specimens are required in order to assure compressive failure in the tested face-sheet, making the test both demanding and expensive. On the other hand, lower load levels are required to break the specimens and there is less need for precise machining during specimen manufacturing. A finite element model including progressive damage evolution was used to estimate the post impact strength. The simulations showed generally good agreement with the experiments.

Post infectional alterations caused by Xylaria polymorpha in the secondary xylem of Lannea coromandelica (Houtt.) Merr

- Xylaria polymorpha is known to cause root rot disease in hardwood trees. In the present study, trees of the species Lannea coromandelica infected with X. polymorpha showed symptoms consistent with root rot disease and also presented with a soft rot decay pattern. Bright-field microscopy, Confocal Microscopy, and Scanning Electron Microscopy revealed that fungal mycelia penetrated the S2 layer of the fiber wall while axial parenchyma was found to be relatively resistant without much visible damage. Occasionally, separation of the parenchyma adjacent to fiber occurred due to the dissolution of the compound middle lamella. Ray parenchyma cells showed several boreholes having irregular shapes and sizes. Enlargement of the pits in axial and ray parenchyma was present in all the samples investigated. Xylem fibers were the most susceptible cell type and developed several tunnels through the S2 layer. Tunnels formed in the S2 layer of the fiber wall by the mycelia showed L- and/or T-bending. The diameter of the tunnels started narrow, increasing in size as the tunnels extended into the S3 layer. In some instances, complete removal of the S3 layer and fusion of the tunnels with the fiber lumen appearing as U-shaped erosion troughs was observed. At the advanced stage of decay, extensive damage was observed in the vessel walls, leaving the middle lamella and wall layer facing the vessel lumen intact. In conclusion the anatomical characteristics observed in the present study suggests that X. polymopha is an aggressive saprobe with strong ligninolytic activity causing soft rot type 2 decay in the wood cell wall of Lannea coromandelica.
