However, it is susceptible to fungal attacks, particularly by <em>Trametes pini</em> (M'jej), which causes rot and renders the wood unusable. This leads to significant financial losses, exceeding 30 %. The purpose of the study was to use Arbotom tomography equipment to measure the degree of <em>Trametes pini</em> infection to evaluate the health of the trees. To delineate changes in the affected biopolymers, morphological and elemental investigations were conducted using scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS) and infrared vibrational spectroscopy (IR). Furthermore, inductively coupled plasma spectrometry (ICP) analysis was employed to accurately quantify the mineral composition in the wood specimens. The results indicated a robust correlation between the visually observed degradation in tree parts and the degradation quantified through tomography. For samples from degraded trees, the accuracy rate was 100 %, emphasizing the impact of fungi on lignocellulosic materials by altering the cellulose content, which was 37.00 ± 1.41 % for healthy wood and 8.00 ± 3.26 % for infected wood. There was also a modification in the hemicellulose content, increasing from 15.67 ± 0.94 % for healthy wood to 62.00 ± 3.56 % for infected Atlas cedar wood. Additionally, there was a modification in the mineral content. This study unveils the parallels and distinctions in the chemical composition and morphological structure between cedar wood and its biowaste. These findings open avenues for prospective value-added applications in pertinent fields.</div></div>","PeriodicalId":21690,"journal":{"name":"Scientific African","volume":"27 ","pages":"Article e02576"},"PeriodicalIF":2.7,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three groups of crayfish were subjected to study, each containing 20 individuals. Group I served as the control with tap water; Group II was exposed to HWW, and Group III received nano-HWW for 28 consecutive days. The research demonstrated that HWW treated with nanocomposite (NiFe₂O₄) may decrease the impairment effects of HWW exerted on the HP and muscles. This improvement was attained by reducing the HP and muscles' toxicity through lowering nitric oxide contents, lipid peroxidation, protein carbonyl, and 8‑hydroxy- deoxyguanosine, while decreasing total antioxidant capacities, cytochrome P450, adenosine triphosphate, and calcium. Additionally, ameliorations were detected in the histological structure of the HP and muscles.

The study utilizes secondary data from the World Health Organization (WHO) and Our World in Data, covering the period from 2020 to 2022.

However, the necessity for high cement content leads to considerable environmental and economic concerns. Consequently, there is an urgent need to explore more eco-friendly alternatives that can sustain the performance of HPC while meeting technical, economic, ecological, and sustainability requirements. One viable option is natural pozzolan (NP), which is abundantly available in many regions and can serve as a partial replacement for cement. . Algeria, for instance, has abundant and low-cost NP, which can significantly decrease clinker demand and enhance eco-concretes' performance. Our objective is to assess how partially substituting cement with NP with a replacement rate ranging from 0 % to 50 % affects the physical, mechanical behavior, and durability of Eco-HPC made with ternary binders. Experimental results indicate that eco-HPC, which includes up to 20 % NP, shows good performance. After 28 days, it achieves a compressive strength of 63.8 MPa, slightly lower than the control HPC's 68.5 MPa. In addition, its long-term strength development reached 84.4 MPa at 180 days compared to 78.2 MPa for the control HPC. Furthermore, the 20 % pozzolan mix demonstrates 15 % less total shrinkage at 180 days and a 25 % decrease in capillary water absorption when compared to the control mix, while retaining adequate workability.
