On the language of liberalism
Authors: Stanisz-Lubowiecka Anna 
Published: November 2023

Abstract
In this article, I look at linguistic studies of communist propaganda produced by oppositional scholars in the
last two decades of state socialism in Poland. I argue that Polish discourse of linguistics in 1970–1989 was a vehicle for the
promotion of liberalism in the People’s Republic of Poland and an important area of political contestation. I demonstrate that
Polish linguistic studies of communist propaganda should not be assumed to be “objective” or politically disengaged. Ideas about
language detectable in these studies, especially “referentialism”, promote liberal democracy by consistently implying values
characteristic of liberalism as a political ideology. In this way, Polish linguists engaged in a form of anti-communist resistance
and formulated language policy proposals for the language of liberal democracy. I argue that language ideologies are sometimes
systematically related to political ideologies by promoting specific political values or points of view.
The paradigmaticity of evidentials in the Tibetic languages of Khams
Authors: Drolma Dawa , Suzuki Hiroyuki 
Published: November 2023

Abstract
This article argues that the evidential system of Khams Tibetan, a cluster of Tibetic languages spoken in the
south-eastern Tibetosphere, should be considered a verb paradigm. We propose a paradigm with six evidential categories (egophoric,
statemental, visual sensory, nonvisual sensory, sensory inferential, and logical inferential) for all the verb classes. We focus
on two varieties – rGyalthang and Lhagang – and examine how these evidential categories are encoded with distinct morphemes. We
then discuss the main evidential forms of the copulative and existential verbs available in Khams Tibetan varieties as a whole, as
well as their morphological relationship. Our analyses lead us to argue against a differential treatment of evidentiality
depending on verb categories. The article concludes that describing the evidential paradigm may be the first essential task in
writing a grammar of a Tibetic language.
Proposed holistic strategy for mechanical recycling of wind turbine blades for 3D printing and compression molding

Published: November 2023

Abstract
There are many solutions being proposed for recycling discarded wind turbine blades, but most solutions are not very ecological, involving either burning or harsh chemicals. In this research, a solution is proposed that has a very low environmental impact and has potential of being scaled to a very large industrial process. The entire wind turbine blade should be recycled and transformed into other products that are recycled and that have economic benefits in the long term. Two of the output products from the current recycling strategy are recycled 3D printing filament and recycled reinforced pellets for compression molding. The research outlines the process, the numerical simulations that help optimize the output and the outline for planning to bring the recycling solution from a small industrial scale to a large scale. This represents ongoing research in this important field of composite recycling.
Constraining effect of load frames during full-scale rotor blade fatigue testing
Authors: Klaenfoth F , Melcher D , Nickel A , Block T , Petersen E 
Published: November 2023

Abstract
In rotor blade fatigue tests used for the certification process, load frames are used to introduce the loads to the blade. These load frames have a constraining effect on the cross-sectional deformation. This work investigates these constraining effects using a finite element contact analysis on a current-generation commercial rotor blade. Two different load frame variants are considered: a conventional load frame covering most of the cross-section and a reduced load frame covering only the main spar caps. The interaction between blade and load frame is implemented via contact formulations, which allows pretensioning in combination with a flap and a lead-lag load case. Strains on the outer surface of the blade are evaluated and compared to an artificial reference loading. The area of influence of the load application through the load frame, in which the strains deviate significantly due to clamping effects, mostly corresponds to the 0.75 times the chord length assumed for the certification [1]. The strains in the trailing edge are significantly less affected by the reduced load frame variant than by the conventional one, thus potentially making it possible to consider the trailing edge at the position of the load frame as being properly tested for certification purposes.
Experimental testing method to characterise the drapability of UD non-crimp fabrics used in wind turbine blades

Published: November 2023

Abstract
This scientific article presents a novel approach for characterising the drapability of fabrics used in wind turbine blade production. This study defines drapability as an intrinsic property of fabric to shear. Specifically, it refers to the potential of the rovings to slide with respect to each other. The evolution of wrinkles has been quantified by the ratio of height-to-width corresponding to a shear angle. The growing industrial interest in binder fabrics, for their preforming ability and improved handling leading to faster blade production, has motivated this study. In this research, two types of non-crimp fabrics, with and without binder, were analysed to study the evolution of wrinkles concerning applied shear angles. A state-of-the-art 3D blue light scanning technique is employed to accurately measure the aspect ratio (height/width) of wrinkles at various shear angles, including 0°, 4°, 6°, 8°, 12°, and 16°. A wrinkle having an aspect ratio of 1/10 was determined to correlate with an applied shear angle of 9° for non-binder fabrics, and 3° for binder-based fabrics. The findings clearly demonstrate the influence of binders on fabric drapability, reducing it by a factor of three. These results provide valuable insights into the influence of different parameters on wrinkle formation, aiding in controlling these factors to avoid manufacturing defects in wind turbine blades.
Life cycle assessment of wind turbine blade recycling approaches in the United States

Published: November 2023

Abstract
Most wind turbine blades reaching end-of-life are sent to landfill where embedded cost, energy, and materials are lost. To avoid landfilling future blades, a broad range of recycling and material recovery approaches have been proposed as solutions in the U.S., each with benefits, challenges, and varying levels of technical maturity. The approaches include 1) cement co-processing, 2) mechanical recycling, 3) pyrolysis, 4) microwave pyrolysis and 5) solvolysis. While these approaches are all capable of recovering various forms of materials for use in secondary markets, there are trade-offs between material circularity, reducing harmful environmental emissions, and cost-effectiveness for the U.S. market. Life cycle assessment (LCA) is a critical step needed to compare these trade-offs and determine where future research and development should be focused. As a result, some previous LCA has been performed on recycling approaches. However, attempts to quantify and compare greenhouse gas emissions across a broad range of technologies have been limited, particularly within the U.S. market where landfill availability and costs do not hinder disposing of wind blades. This work addresses this limitation by presenting a detailed comparison of LCA greenhouse gas emissions and material yields from a range of wind turbine blade recycling approaches in the U.S. The LCA presented in this work includes baseline results, as well as a variety of sensitivity and scenario analyses that look at the impact of process modelling uncertainty, future energy mixes, and other critical input parameters. Overall, results show that mechanical recycling and microwave pyrolysis have the lowest net greenhouse gas emissions. However, the value of mechanically recycled materials is highly uncertain, as mechanical recycling generates a mixed feedstock that may underperform compared to virgin materials. Cement co-processing has higher net emissions than mechanical recycling or microwave pyrolysis but does generate a value-added feedstock that offsets virgin material from mining for cement production. Other advanced thermal and chemical recycling methods such as pyrolysis and solvolysis have higher net emissions due to increased energy consumption but are also highly sensitive to thermal energy sources within the model.

Published: November 2023

Abstract
Wrinkles are defects prone to occur during the manufacturing process of wind turbine blades. Wrinkles can emerge at various locations of the structure, exhibiting a range of diverse shapes. Different manufacturing steps can lead to different defect types. This work presents different manufacturing methods to embed artificial wrinkle defects in laminates representing a typical defect that can be found in a wind turbine blade. Several methods are tested at coupon scale to design a critical wrinkle defect that can lead to the blade structural knock-down on the mechanical performance during high cycle fatigue operation. Following the selection of the defect types for investigation at the test coupon scale, the corresponding defect types are embedded while manufacturing a 12.6 m wind turbine blade.

Published: November 2023

Abstract
This study aims to contribute to the ongoing efforts to enhance the reliability and durability of wind turbine blades, a critical component in wind energy generation. Specifically, this research addresses the issue of tunneling cracking and severe damage that can occur in wind turbine blades due to cohesive failure of the trailing edge. To achieve this objective, the study employs a rigorous approach, utilizing a full three-dimensional (3D) modeling strategy with finite element analysis (FEA) to simulate the behavior of wind turbine blades. The effect of cohesive materials and layered simulation methods on the thermal residual stress and crack propagation is thoroughly investigated. In particular, the study assesses the influence of carbon fiber-reinforced polymer (CFRP) and glass fiber-reinforced polymer (GFRP) materials on the phenomenon under consideration. In addition, the study undertakes a comprehensive parametric analysis to identify the independent effects of material properties and numerical simulation on thermal residual stress. Moreover, the research explores the behavior of the cohesive zone model in terms of thermal residual stress and crack propagation. The findings of this study have significant implications for researchers and practitioners in the wind energy industry. The study’s outcomes can aid in the development of improved materials and simulation techniques to mitigate thermal residual stress and prevent the occurrence of tunneling cracking and other types of damage in wind turbine blades. As such, this research contributes to the broader efforts to advance the reliability, efficiency, and sustainability of wind energy generation.

Published: November 2023

Abstract
Recycling glass fibre reinforced thermoset composites remains a challenge despite years of research in the field. Among the barriers for a successful recycling, the properties of the recycled materials and their application in new products represent the main ones. With a pyrolysis recycling process, clean glass fibres can be extracted and separated from the polymer matrix. In this paper, recycled glass fibres are incorporated in a new polymer composite structure using both virgin and recycled glass fibres. Recycled glass fibres have a Young’s modulus comparable to virgin glass fibres. The objective is to identify a composite lay-up using virgin and recycled glass fibres, and where the Young’s modulus of recycled fibres is beneficial for the resulting composites mechanical properties. To do so, a sandwich structure composite with virgin fibres on the outer layer and recycled fibres in the inside is designed and manufactured. In order to produce flat panels despite the short and random fibres, a manufacturing procedure ensuring a good dispersion of the fibres and controlling the thickness of the panel is developed. Panels are produced incorporating two different weight fraction of recycled glass fibres. The quality of the panels are characterized using microstructure observations, fibre porosity analysis and mechanical testing. Results shows that the sandwich composites have a low porosity content and achieves higher bending stiffness than a composite only made of unidirectional virgin glass fibres.
Prediction of crack growth at trailing edge bondlines of a wind turbine rotor blade for the assessment of remaining service life

Published: November 2023

Abstract
Debonding along trailing-edge joint of a wind turbine rotor blade is one of the often reported failure modes during the rotor blade maintenance inspections. This study focuses on buckling-induced debonding along the trailing edge under in-plane compressive loads due to the gravity forces on the rotor blade. With a priori known debond crack length, an analytical model is used for predicting debond growth rate and assessing the time that takes the crack to reach a critical length. For the growth rate prediction, required input parameters are size of the initial debonding, laminate and adhesive layer thicknesses, elastic and interfacial fracture mechanics properties, gravitational load distribution and position of the initial debonding. The damage model is implemented in excel spreadsheet tool. The predictions of the analytical model were compared with the results from 3D finite element simulations and the difference between the results (energy release rate) was 8%. This study demonstrates how damage specific tools can be developed for predicting remaining useful life of rotor blades.
Study on recycling wind turbine blades into reinforcement for filaments used in 3D printing
Authors: Ezhilan J James , Damodaran Ajith , Ashok K G 
Published: November 2023

Abstract
Heavy applications like power production through wind energy requires light weight but strong material like composites with customizable properties. When the lifetime of the wind turbine blades ends, the parts are dumped in landfills and results in environmental pollution. Natural fibers are great option for improving the biodegradability of the conventional plastic which also ends up in the landfills. Fused Filament Fabrication (FFF) is chosen to combine the benefits of both materials, as the technique is highly customizable and sustainable. Wind turbine blade wastes are recycled using mechanical grinding. Recycled Fiber glass (FG) material is tested for contamination with Fourier Transform Infrared Spectroscopy (FTIR). Wood fiber (WF) is also added in order to improve biodegradability of the materials. Filaments are produced using a single screw extruder with various combinations of 9 wt% fiber content and recycled pellets. Tensile test shows comparable performance of reinforced filaments with recycled Polypropylene (PP) filaments. 6% WF + 3% FG sample withstood up to 380 MPa Young’s modulus.
Most soil and litter arthropods are unidentifiable based on current DNA barcode reference libraries

Published: November 2023

Abstract
We are far from knowing all species living on the planet. Understanding biodiversity is demanding and requires time and expertise. Most groups are understudied given problems of identifying and delimiting species. DNA barcoding emerged to overcome some of the difficulties in identifying species. Its limitations derive from incomplete taxonomic knowledge and the lack of comprehensive DNA barcode libraries for so many taxonomic groups. Here, we evaluate how useful barcoding is for identifying arthropods from highly diverse leaf litter communities in the southern Appalachian Mountains (USA). We used 3 reference databases and several automated classification methods on a data set including several arthropod groups. Acari, Araneae, Collembola, Coleoptera, Diptera, and Hymenoptera were well represented, showing different performances across methods and databases. Spiders performed the best, with correct identification rates to species and genus levels of ~50% across databases. Springtails performed poorly, no barcodes were identified to species or genus. Other groups showed poor to mediocre performance, from around 3% (mites) to 20% (beetles) correctly identified barcodes to species, but also with some false identifications. In general, BOLD-based identification offered the best identification results but, in all cases except spiders, performance is poor, with less than a fifth of specimens correctly identified to genus or species. Our results indicate that the soil arthropod fauna is still insufficiently documented, with many species unrepresented in DNA barcode libraries. More effort toward integrative taxonomic characterization is needed to complete our reference libraries before we can rely on DNA barcoding as a universally applicable identification method.

Authors: Fu Chun , Yang YaoJun 
Published: November 2023

Abstract
With the continuous upgrading of high-throughput sequencing technology, a large amount of biological genome data has been deciphered and published. The research on functional genes of biological genomes urgently needs a collection of service websites with user-friendly and full annotation functions for a variety of gene function annotation tools. In this study, iCAZyGFADB, which is a database website integrating nine gene function annotation tools, was perfectly developed to meet the needs of biological genome functional annotation. Its nine gene function annotation tools were Carbohydrate-Active Enzymes (CAZyme) annotation, Gene Ontology (GO) annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation, Cluster of Orthologous Gene (COG) annotation, Evolutionary Genealogy of Genes: Non-supervised Orthologous Groups (eggNOG) annotation, SwissProt annotation, Pfam annotation, KOG annotation and Animal Transcription Factor DataBase (AnimalTFDB) annotation. It has three advantages. First, it is superior to gene function annotation of other biological cloud analysis platforms and runs very fast. Second, all gene annotation functions of the website are free and open to users. Third, it can annotate eight gene functions (GO, KEGG, COG, eggNOG, SwissProt, Pfam, KOG and AnimalTFDB annotation) of a single species at the same time, while other cloud platforms do not have the ability or need to charge to open for users to complete the annotation of eight gene functions at the same time. Moreover, the development and operation of our database will provide great help for gene function annotation research and significantly improve the efficiency of genome function research and reduce the cost of bioinformatics analysis. Genomic functional annotation researchers can access this database through the following website: http://www.icazygfadb.org.cn/.

Abstract
Bacterial wilt caused by Ralstonia solanacearum is a severe soil-borne disease globally, limiting the production in Solanaceae plants. SmNAC negatively regulated eggplant resistance to Bacterial wilt (BW) though restraining salicylic acid (SA) biosynthesis. However, other mechanisms through which SmNAC regulates BW resistance remain unknown. Here, we identified an interaction factor, SmDDA1b, encoding a substrate receptor for E3 ubiquitin ligase, from the eggplant cDNA library using SmNAC as bait. SmDDA1b expression was promoted by R. solanacearum inoculation and exogenous SA treatment. The virus-induced gene silencing of the SmDDA1b suppressed the BW resistance of eggplants; SmDDA1b overexpression enhanced the BW resistance of tomato plants. SmDDA1b positively regulates BW resistance by inhibiting the spread of R. solanacearum within plants. The SA content and the SA biosynthesis gene ICS1 and signaling pathway genes decreased in the SmDDA1b-silenced plants but increased in SmDDA1b-overexpression plants. Moreover, SmDDB1 protein showed interaction with SmCUL4 and SmDDA1b and protein degradation experiments indicated that SmDDA1b reduced SmNAC protein levels through proteasome degradation. Furthermore, SmNAC could directly bind the SmDDA1b promoter and repress its transcription. Thus, SmDDA1b is a novel regulator functioning in BW resistance of solanaceous crops via the SmNAC-mediated SA pathway. Those results also revealed a negative feedback loop between SmDDA1b and SmNAC controlling BW resistance.
