Influence of Woven-Fabric Type on the Efficiency of Fabric-Reinforced Polymer Composites

The greatest advantage of fiber-reinforced composite materials is the freedom to tailor their strength and stiffness properties, while the most significant disadvantage consists in their high costs. Therefore, the design process and especially the optimization phase becomes an important step. The geometry of the fabric of each lamina as well as their stacking sequence need to be carefully defined, starting from some basic geometric variables. The input parameters are the widths and the heights of the tows, the laminate-stacking sequence and the gaps between two successive tows or the height of the neat matrix. This paper is a follow-up to a previous work on using and improving an in-house software called SOMGA (Satin Optimization with a Modified Genetic Algorithm), aimed to optimize the geometrical parameters of satin-reinforced multi-layer composites. The final goal is to find out the way in which various types of woven fabrics can affect the best possible solution to the problem of designing a composite material, able to withstand a given set of in-plane loads. The efficiency of the composite structure is evaluated by its ultimate strains using a fitness function that analyses and compares the mechanical behavior of different fabric-reinforced composites. Therefore, the ultimate strains corresponding to each configuration are considered intermediate data, being analyzed comparatively until obtaining the optimal values. When the software is running, for each analysis step, a set of intermediate values is provided. However, the users do not have to store these values, because the final result of the optimization directly provides the composite configuration with maximum efficiency, whose structural response meets the initially imposed loading conditions. To illustrate how the SOMGA software works, six different satin-woven-fabric-reinforced composites, starting from plain weave (satin 2/1/1), then satin 3/1/1, satin 4/1/1, satin 5/1/1, satin 5/2/1 and finally satin 5/3/1, were evaluated in the SOMGA interface. The results were rated against each other in terms of the composite efficiency and the case characterized by minimal reinforcement undulation (thinnest laminate) were highlighted

HPLC Analysis of Polyphenolic Compounds in <em>Lysimachia nummularia</em> L. and Comparative Determination of Antioxidant Capacity

Lysimachia nummularia L. is a perennial herbaceous plant rich in bioactive compounds, which can be utilized for medicinal purposes. The present work aims to analyze the phenolic compounds from different parts of the Lysimachia nummularia L. plant using the HPLC technique: Lysimachiae radix (the root part), Lysimachiae herba (the aerial part), Lysimachiae flores (flowers). In order to determine the phenolic compounds, extraction from the three categories of vegetable products was performed with ethanol 70% (v/v) using three extraction methods: (i) Soxhlet extraction, (ii) maceration and (iii) ultrasonic-assisted extraction. The content of polyphenols was determined by the Folin–Ciocalteu method, and the antioxidant activity was evaluated by the DPPH, ABTS, FRAP and CUPRAC methods. The antioxidant activity was correlated with the content of phenolic compounds in the analyzed extracts. The following phenolic compounds were separated, identified and quantified: 3-O-methylgallic, gallic, ferulic, caffeic, chlorogenic, p-coumaric acids and trans-resveratrol. According to the experimental data, the highest content of total polyphenols was observed in the hydroethanolic extract from Lysimachiae flores (22.10 ± 1.48 mg gallic acid/g), which also presented remarkable antioxidant activity

Universal Dependencies 2.5

Universal Dependencies is a project that seeks to develop cross-linguistically consistent treebank annotation for many languages, with the goal of facilitating multilingual parser development, cross-lingual learning, and parsing research from a language typology perspective. The annotation scheme is based on (universal) Stanford dependencies (de Marneffe et al., 2006, 2008, 2014), Google universal part-of-speech tags (Petrov et al., 2012), and the Interset interlingua for morphosyntactic tagsets (Zeman, 2008)
