The most representative parts of the bamboo culm were selected using microscopic images of bamboo cross-sections.

Four-point bending tests were conducted on twelve culms of <em>Phyllostachys aurea</em>, subdivided into groups of untreated (UN) and heat-treated (HT) samples. The axial modulus of elasticity (E<sub>b</sub>) and the shear modulus (G) were determined experimentally using four different mathematical models: (i) a global deflection model using the Euler-Bernoulli beam theory according to the ISO Standard; (ii) a global deflection model using the Timoshenko beam theory; (iii) a global deflection model based on the Timoshenko beam theory but accounting for the presence of nodes; and finally, (iv) a local model using extensometry. The dominant failure modes for UN and HT samples are described and discussed, and were influenced by the moisture content (MC). Approaches (i) and (ii) showed good agreement, giving reliable parameters to assess E<sub>b</sub>. The third approach (iii) indicated that the nodes significantly influence the flexural behaviour of the culms. Approach (iv) was appropriate for determining G, but resulted in higher values of E<sub>b</sub>, typically not representative of the material.</p></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773139124000454/pdfft?md5=fa55d9f5240124ade439d16746dd4128&pid=1-s2.0-S2773139124000454-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142129672","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}

The versatility of the species means that it has enormous potential for land restoration in arid and semi-arid areas, in addition to bringing socio-economic benefits. It also displays remarkable adaptability, allowing it to thrive in the challenging ecological conditions of areas such as the Abay Gorge. The Abay Gorge, situated within the Upper Blue Nile River Basin of Northwestern Ethiopia is characterized by problems associated with soil erosion and land degradation. This study, therefore, aimed to evaluate and recommend a suitable spatial analysis for the adoption and development of lowland bamboo (<em>O. abyssinica)</em>. Fifteen primary influencing factors were chosen according to the needs of <em>O. abyssinica</em>, the accessibility of data, and the financial implications associated with data analysis, particularly the expenses related to soil laboratory testing. Eight composite soil samples were taken directly by dividing the watershed into two categories (upper and lower catchment areas). These composite soil samples were analyzed. Data analysis was performed via Analytical Hierarchy Process (AHP) in conjunction with Multi-Criteria Decision-Making (MCDM) analysis and the use of Remote Sensing (RS) and Geographic Information System (GIS). The spatial analysis employed in this study was a weighted sum overlay analysis, which was applied by considering the criteria weight assigned to each factor. The analysis revealed that 21.2 % (666.5 ha) of the total area was highly suitable for the growth and development of <em>O. abyssinica</em>. About 56 % (1753 ha) of the land was moderately and marginally suitable for the desired land utilization type. However, 23 % (723.8 ha) of the study area was unsuitable for <em>O. abyssinica</em>. <em>O. abyssinica</em> has the potential to rehabilitate large parts of challenging areas such as the Abay Gorge due to its naturally invase rhizomes and drought-tolerance.

Differences in carbon substrate utilization patterns can be separated by microbial community structure analysis, especially at the end of composting.

A clear understanding of the vertical distribution of leaf biomass is essential for accurate carbon sequestration estimations in Moso bamboo. We collected data on leaf biomass from each crown layer and the structural characteristics of 54 individual Moso bamboo plants. We then simulated the vertical distribution of normalized upward cumulative leaf biomass (CLBn) using three power functions. The first model (Model 1) estimates CLBn using unique and unadjustable parameters (<em>a</em> and <em>b</em>) of the power function. In the second model (Model 2), parameter ‘<em>a</em>’ was fixed at 1, and parameter ‘<em>b</em>’ was fitted for all samples. In the third model (Model 3), parameter <em>b</em> was adjusted based on the structural characteristics of each bamboo. Model 3 demonstrated the highest accuracy in estimating CLBn and normalized leaf biomass (LBn) in each layer, with RMSEr values of 20.34 % and 36.85 % for CLBn and LBn, respectively. When compared with Model 1 and Model 2, Model 3 reduced RMSEr by 12.27 % and 6.88 % for CLBn and 21.13 % and 10.49 % for LBn, respectively. However, uncertainty remained significant in low LBn estimates from Model 3. Variations in the vertical distribution of CLBn in individual bamboo plants were primarily explained by crown length, height to the lowest living branch, and age.
