title: Genome-Wide Analysis of the PLATZ Gene Family and Identification of Seed Development-Related Genes in Flax [<i>Linum usitatissimum</i> L.]

description: The plant AT-rich sequence and zinc-binding proteins (PLATZ) are a new class of zinc-dependent DNA-binding proteins that play important roles in plant growth and development. But it has not been systematically identified in flax (Linum usitatissimum L.), as an important seed crop with high nutritional value. In this study, 28 LuPLATZ proteins were identified from flax and divided into six phylogenetic groups. Fragment duplication was an important driving factor in the evolution of <i>LuPLATZ</i> genes. The RNA-seq results showed that the LuPLATZ genes had different expression patterns. Quantitative analysis of 16 <i>LuPLATZ</i> genes was performed, and the qRT-PCR results were consistent with the RNA-seq results. The expression of <i>LuPLATZ6</i>, <i>LuPLATZ23</i>, and <i>LuPLATZ27</i> increased significantly during seed development. The observed change in the expression pattern suggests that these three genes could have significant regulatory functions during seed formation. These three LuPLATZ proteins were localized to the nucleus, suggesting that they could be conventional transcription factors. <i>LuPLATZ23</i> and <i>LuPLATZ27</i> were co-expressed with LuNAC1 and LuNAC75, suggesting an interactive relationship. This study aims to offer a theoretical foundation for high-yielding molecular breeding of flax.

title: Exploring Genetic Variability and Morpho-Agronomic Trait Associations Among Ethiopian Flax (<i>Linum Usitatissimum</i> L.) Accessions for Enhanced Fiber and Seed Yield

description: Flax is a versatile crop grown for its fiber and seed oil. Despite extensive conservation efforts in Ethiopia, the genetic potential of flax accessions conserved in the gene bank remains largely underexplored for fiber and seed yield. Here, we aimed to assess the genetic variability and association of morpho-agronomic traits and identify potential accessions for fiber and seed yield among 150 flax accessions. The study was conducted at Holeta Agricultural Research Center during 2022/23 growing season using an augmented design. Data were collected on flowering and maturity dates, plant and technical height, basal and secondary branch, boll and seed numbers, 1000-seed weight, and yield. Results revealed significant variation both between blocks and within treatments, with flowering time, maturity, plant height, boll number, seed weight, and yield contributing for the highest variability (58.7%). Cluster analysis revealed nine distinct genetic groups, each exhibiting specific trait patterns. Seed yield had strong associations with maturity, plant height, and boll number. High broad-sense heritability for days to flowering, plant height, and yield traits suggests selection could be effective based on phenotypic expressions. The study highlights the potential of Ethiopian flax genetic diversity for enhancing fiber and seed yield, suggesting effective selection based on key traits.

title: A Comparison of the Physical Properties Between Merino Wool and Camel Hair Through Discriminant Analysis

description: The applicability of camel hair is still conditioned by a gap in the knowledge about this raw material, which in turn hinders its supply chain, commercial possibilities, and the value that the product reaches in the market. The present research compares the physical-mechanical properties of Canarian camel hair versus Merino sheep wool, the world’s most popular proteinic fabric material, using a discriminant canonical analysis. The attributes that maximized differences between both types of animal-origin fibers were related to average fiber diameter, fineness, length staple, and residual dirt. Although slightly shorter than sheep wool, camel hair can reach a prominent fabric quality and spinning performance given its greater average diameter and its lower variation within small fragments along the snippet, as well as the higher distance from the tip to the finest point in the staple, which is an indicator for the breaking point. Such characteristics are known to increase bending rigidity during the manufacturing process. Residual dirt may be associated with the low-input, extensive exploitation of camels. The present paper provides a reference for maturing pre-process and manufacture techniques for the further valorization of camel hair in the present-day textile industry and, thus, engages income opportunities for this livestock production.

title: Design of Recyclable Adsorbent for Water Pollutants Based on Chitosan-Coated Carboxymethyl Cellulose-Calcium Alginate Wrapped Iron Oxide-Copper Oxide Composite Beads

description: In this study, an efficient nanocomposite based on calcium alginate-carboxymethyl cellulose/iron oxide-copper oxide (CA-CMC/Fe<sub>2</sub>O<sub>3</sub>-CuO) is developed in beads form and utilized as nanoadsorbent and nanocatalyst. Further, the beads were coated with chitosan, resulting in Cs@CA-CMC/Fe<sub>2</sub>O<sub>3</sub>-CuO beads. The prepared beads exhibited exceptional adsorption capabilities for selected heavy metal ions. Notably, the Cs@CA-CMC/Fe<sub>2</sub>O<sub>3</sub>-CuO beads displayed remarkable adsorption among the other beads toward the three selected metal ions. Ag(I) was highly adsorbed by Cs@CA-CMC/Fe<sub>2</sub>O<sub>3</sub>-CuO beads, and the adsorption capacity of beads was 4.91 mgg<sup>−1</sup>, while 4.5 mgg<sup>−1</sup> and 3.0 mgg<sup>−1</sup> for Co(II) and Ni(II), respectively. Beads’ ability to adsorb Ag(I) varied depending on several factors. It was observed that the adsorption capacity of Ag(I) ions increased as the interaction time and metal concentration rose. However, increasing the beads dose led to a decrease in the Ag(I) ion adsorption. Further, the waste beads after Ag(I) adsorption were treated with reducing agent to form beads supported Ag nanoparticles (Ag/Cs@CA-CMC/Fe<sub>2</sub>O<sub>3</sub>-CuO) and used as effective catalyst for reducing 4-nitrophenol in the presence of NaBH<sub>4</sub> as a reducing agent. Ag/Cs@CA-CMC/Fe<sub>2</sub>O<sub>3</sub>-CuO achieved reduction up to 93% for 4-NP within 30 min. The designed nanocomposite beads displayed several desirable attributes, including eco-friendliness and robust catalytic performance, making them highly promising for useful reduction of 4-NP.

title: Evaluating the Comfort Properties of Single Jersey Knitted Fabrics

description: In today’s textile industry, the comfort of a fabric often preponderates its importance in price. The concept of “fabric handle” - the tactile sensation experienced when touching a fabric – plays a crucial role in shaping consumer perceptions and product functionality. This fact greatly influences consumer perceptions of fabric quality during shopping and affects the functionality of textile products in everyday use. This study aimed to explore the comfort properties by using 10 different samples of knitted fabric. Ten single-knit jersey fabrics covering a wider range of commercial uses were used to objectively evaluate the fabric hand properties. The Kawabata evaluation system assessed the mechanical properties, including tensile strength and shearing resistance, bending rigidity, compressional performance, and surface characteristics determining fabric comfort. The material composition has been shown to affect the functional characteristics of fabrics to comply with consumer needs and preferences.

title: Influence of Utilization of Natural Waste Fibers Pyrolysis on Mechanical Properties and Microstructure of Concrete

description: The main purpose of this paper is to investigate the impact of the thermal processing of natural fibers on the strength of what is considered fiber-reinforced concrete. Natural fibers extracted from palm trees and bamboo residues were collected and pyrolyzed. The investigation of the morphological alterations that occur during the pyrolysis of natural fibers at a temperature of 200°C showed the impact of the cementitious environment on this process. In addition, the mechanical characteristics of fiber-reinforced concrete were conducted on different dosages (1, 1.5, 2, and 5% wt.) of treated and untreated palm oil, date kernel, and bamboo fibers. The results demonstrated that the inclusion of fibers up to 1.5% wt. enhanced the concrete mixes mechanical properties, which included pyrolyzed fibers. Analyzes of the concrete microstructure revealed that the treated fibers were not damaged. The 1.5% wt. addition of fibers after pyrolysis process can effectively improve their adhesion to the matrix and reduce the width and number of cracks. The analysis of variance results for flexural strength indicated that all sources had no significant impact on the flexural strength of untreated or pyrolysis treated natural fiber reinforced concrete.

title: Analysis of Water Absorption on the Young’s Modulus and Damping of Sponge Gourd (<i>Luffa cylindrica</i>) Composites

description: Composites reinforced with lignocellulosic fibers are attracting attention for use in several applications. This fact is directly linked to the advantages of using renewable lignocellulosic fibers. However, due to their cellulose-based structure, lignocellulosic fibers easily absorb water, which can affect the behavior of the composites. Surface treatments are used to reduce the hydrophilicity of fibers, but common surface treatments use chemicals, compromising the green approach of using lignocellulosic fibers. This work compares the water absorption behavior of sponge gourd-epoxy matrix composites with untreated and surface treated fibers. The effect of these treatments on the variation of the Young’s modulus and damping factor of the composites during the immersion time in distilled and salt water was also evaluated using the nondestructive impulse excitation test. In addition to the commonly used surface treatments (mercerization and acetylation), hornification has also been used to reduce the use of chemicals. The results obtained show that hornification is a competitive approach to reduce the water absorption of composites, being an interesting alternative to chemical surface treatments. A relationship was established between the amount of water absorbed and the variation in Young’s modulus and damping factor. Both properties stabilized when the water absorption saturation value was reached.

title: Unveiling the Impact of Acetic Acid: Multi-Analytical Assessment for Characterizing Accelerated Aging in Raw Silk and Sappanwood-Dyed Silk

description: In this study, raw and sappanwood-dyed silks were exposed to varying concentrations of acetic acid vapor to investigate aging degradation by colorimetry, SEM, FTIR, ATR-FTIR, and HPLC. The findings illustrate that acetic acid gas could lead to increase in color difference, decrease in the relative contents of crystalline regions, and changes in amino acid contents. Therefore, the aging process could be characterized as a progressive procedure: (i) initial stages were marked by color changes, (ii) gradual acid hydrolysis occurred within the protein crystalline region in the intermediate phase, and (iii) diverse trends of increase or decrease in different amino acids prevailed during the final stage of aging. Additionally, raw and sappanwood-dyed silks deteriorated further with acetic acid solution. Colorimetry and SEM showed more severe damage in dyed silk with rougher surfaces and more fiber breakage, indicating that acidic gas in water could cause greater damage and highlighted greater vulnerability of dyed silk. This study innovatively used multiple analytical methods to explore the long-term effects of acidic environments on silk and filled gaps in gas-induced aging research. It emphasized the necessity and importance of addressing gas pollution in museums and sounded the alarm of its damaging effects on silk artifacts.
