On the elemental contents of aspen (Populus tremula L.) leaves grown in the mineralization area

The aim of this study is to investigate the behavior of major and trace elements in aspen leaves grown in an intensely altered region from a geochemical point of view. In this context, major and trace element contents of aspen leaves (Populus tremula L.) grown on Gümüştuğ (Gümüşhane/Türkiye) antimony mineralization were investigated. For this purpose, 56 leaf samples were collected from the field by grid method and at intervals of approximately 50–60 m. After routine sample preparation processes, analyzes were carried out to determine the major and trace element concentrations. Subsequently, elemental concentrations of aspen leaves were evaluated by different statistical methods. As a result, major elements Ca, Mg, Na, K, Al and S concentrations were determined in the range of 2%–3%, 0.23%–0.85%, up to 0.02%, 0.79%–2.01%, 0.01%–0.03% and 0.13%–0.43%, respectively. The trace element concentrations were determined in the range of 127–339 ppm, 86.7–265.30 ppm, 0.1–1.21 ppm, 13.5–453.20 ppm, 6.0–12.0 ppm, 14.0–82.0 ppm and 0.1–0.60 ppm for Mn, Sr, La, Ba, Ti, B and Se, respectively. Considering that the samples were taken from aspen leaves grown on the antimony mineralization, the concentrations of the antimonite element were determined above the detection limit in only a few sampling points in the study. But the concentrations of B, Mn, Sr, La of aspen (Populus Tremula L.) leaves are remarkable.

The Application of Totem Art Culture in Graphic Design Teaching

In the teaching of graphic design, students' learning state and learning effect are poor due to the lack of attractiveness of teaching materials. In order to fully display the graphic design knowledge contained in totem patterns, a model based on the pattern elements of totem patterns was constructed. Through Marvelous Designer software, the display of totem visual effects under different pattern element configurations was realized, providing a basis for the comparative explanation of graphic design teaching. When designing the teaching content, based on the totem art culture, it has constructed three parts of teaching methods of plane composition, teaching contents of plane composition and teaching concepts of plane composition, which correspond to the material selection, composition and freehand brushwork skills of totem patterns in modeling creativity and expression techniques, and the range of material selection, composition form and connotation of plane design teaching, the specific application is realized through knowledge transfer.

A Comparative Analysis of Old and New High School Mathematics Textbooks from the Perspective of Mathematics Core Literacy -- Taking the Trigonometric Function Content of the Human Education Edition as an Example

The promulgation of the Curriculum Standards for ordinary high School (2017 edition, 2020 revision) has effectively promoted the reform of high school mathematics classroom. In order to cope with the change of textbook content in the new curriculum reform, it has become one of the important tasks for high school mathematics teachers to implement teaching activities better and sort out and analyze the differences between the old and new textbooks. This paper analyzes the differences between old and new textbooks from the three dimensions of system structure, course content and example exercises, and gives some reasonable teaching suggestions. Among them, the new textbook uses 2019 "Ordinary High School Textbook" person-taught A version of Compulsory Mathematics 1, and the old textbook uses 2004 "Ordinary High School Mathematics Curriculum Standard Experimental Textbook" person-taught A version of compulsory Mathematics 4. In general, the adjustment of the new teaching materials is more in line with the cognitive characteristics of students, pay attention to the penetration of mathematical culture and pay attention to the development of students' mathematical core literacy.

Salinity tolerance in tomato genotypes at an early plant growth stage: Morphological and physiological responses

Salinity is a significant factor restricting plant development at various stages, resulting in lower yield and productivity. The current study was carried out to investigate and assess the tolerance of several tomato genotypes to salty conditions. Thirty (30) tomato genotypes were cultivated in pots and tested for salinity at three levels: 5 ds/m NaCl, 10 ds/m NaCl, and 15 ds/m NaCl, in comparison to the control (0 mM NaCl). Two weeks after treatment, several morphological and physiological parameters were measured. The effects of salt stress on tomato genotypes included a considerable reduction in leaf area, chlorophyll content, shoot and root length, shoot and root biomass, and relative water content. Different tomato genotypes responded differently to salinity severity score (SSS). Reduction of shoot dry weight (0.27 to 0.44) and leaf area (0.33 to 0.45) were positively correlated with SSS at moderate (10 ds/m) to higher (15 ds/m) salinity levels, respectively. Based on the experiment results, the genotypes BARI Tomato 4, BARI Tomato 14, BARI Tomato 15, SAU Tomato 2, AV₀T₀ 1228, and NS 501 were found to be more salinity tolerant than other genotypes. The results showed that measuring shoot length, leaf area, and shoot fresh and dry weight was better for evaluating salinity stress and screening salt-tolerant tomato genotypes.

Copyright and generative AI

This research investigates the relationship between Generative Artificial Intelligence (GAI), media content, and copyright laws. As GAI technologies continue to evolve and permeate various aspects of the media landscape, questions regarding the creation and protection of intellectual property have become paramount. The study aims to highlight the impact of GAI generated content, and the challenge it poses to the traditional copyright framework. Furthermore, the research addresses the evolving role of copyright laws in adapting to the dynamic landscape shaped by artificial intelligence. It investigates whether existing legal frameworks are equipped to handle the complexities introduced by GAI, or if there is a need for legislative and policy reforms. Ultimately, this research contributes to the ongoing discourse on the intersection of GAI, media, and copyrights, providing insights that can guide policymakers, legal practitioners, and industry stakeholders in navigating the evolving landscape of intellectual property in the age of artificial intelligence.

An Analysis of the Visual Characteristics of Vertical Screen Images in the Era of Intelligent Media Audiovisual

In the era of intelligent media audiovisual, vertical screen images have gradually become the preferred browsing device playback mode for consumers. Taking clarifying the visual characteristics of vertical screen images as a breakthrough point, promoting visual innovation in vertical screen images can provide consumers with a more comfortable and effective visual experience. In view of this, it is necessary to recognize the differences in narrative space between vertical and horizontal banners, the strengthening effect of narrowing narrative space by vertical banners on gaze, and the normative role of audio-visual language transformation in vertical screen image production. The production and innovation of vertical screen image content should grasp the production characteristics and pay attention to visual direction and spatiotemporal integration.
