One of the most widely used solutions to fix and preserve organic tissues is formaldehyde, despite reservations regarding its toxicity and the fact that formaldehyde-embalmed bodies lose their original characteristics. Anatomy laboratories have been replacing formaldehyde with solutions that retain the characteristics of fresh tissue. For this…

Previous work indicates mutual exclusivity in word learning in monolingual, but not bilingual toddlers. We asked whether this difference indicates distinct conceptual biases, or instead reflects best-guess heuristic use in the absence of context. We altered word-learning contexts by manipulating whether a familiar- or unfamiliar-race speaker…

This paper explores how students connect meaningfully with theory through the aesthetic experiences of problem solving together in the context of a workshop. It can be challenging for students studying design in university programs to understand how theory is relevant, when applied in practical design studio activities. In the colour workshop…

The topic of recurrence relations has recently been introduced in many discrete mathematics textbooks. Recurrence relations are efficient modelling and problem-solving techniques used in mathematics. Combinatorial problems are often used to introduce recurrence relations. However, many textbooks consider problems that can be reduced only to the…

This article describes a simple way to introduce nanomaterials using the presence of carbon nanodots (CNDs) in widely available food. Budweiser® beer and Coca-Cola®, commercial foods that are commonly accessible, were utilized to demonstrate the optical property of nanoparticles. Specifically, green and violet laser pointers were employed for the…

Children's brains develop faster in the early years than at any other time in their lives. If you want to make the most of this pivotal period, there is no time to waste. With newly updated research, the second edition of this bestseller provides parents and educators with strategies for building a brain-compatible environment where young learners…

Nowadays, technologies involving nanoparticles, colloids, sensors, and artificial intelligence are widespread in society, media, and industry. It is thus mandatory to integrate them into the curricula of students enrolled in chemistry and materials science. To this purpose, we designed a simple assay for the detection of glutathione (GSH) using…

The article is concerned with educating the concepts "proper name * toponym + anthroponym" linguocultural category and summarizing the analysis with regard to cognitive perception of Nakh-Dagestanian languages. If we consider the interpretation of the terms "proper name * toponym + anthroponym" from viewpoint of cognitive…

We present herein a module of pigment synthesis experiments that could be adapted and implemented in a variety of curricular settings. At the conclusion of each of the past two spring terms at our high school, we offered a 4 day short course on the chemical synthesis of pigments used in art. As part of the course, our students synthesized four…

Test anxiety is prevalent among adolescents. Some potentially successful mindfulness-based coloring interventions have been identified in previous research, however, conclusions have been based on self-report measures only. In the current study, 150 17- to 18-years-olds taking final school exam completed measures of state anxiety (STAI) and…

In light of the COVID-19 pandemic situation, the separation of the primary colors of ink markers and food coloring was performed using a simplified column chromatography setup at home to accomplish the educational outcome of the course. The virtual class instruction, for the students enrolled in the "Organic Techniques Laboratory"…

Steganography is a widely-used technique for digital data hiding. Image steganography is the most popular among all other kinds of steganography. In this article, a novel key-based blind method for RGB image steganography where multiple images can be hidden simultaneously is described. The proposed method is based on Discrete Cosine Transformation…

In this study, the visual assessment of building facades, which define the boundaries of avenues, were based on the color factor with the aim of revealing its effect on the aesthetic perception of a city. Being part of the façade coloring work implemented in the Province of Antalya, the facades along the Avenues of Gulluk, Yuzuncuyil and Mevlana…

This study provides information about the formation of colours with an experimental activity based on the reflection of coloured lights from pigments. The activity shows the formation of colour in a simple and entertaining way. The lights are reflected by being changed by different coloured pigments. This activity provides an opportunity to…

This paper presents the development and structure of indigenous Nahua teachers' ideas about mixing colors, as well their ideas about colors derived from their traditions. For the scientific school knowledge, teachers answered two questionnaires and an interview regarding knowledge from their culture; they were interviewed outside school. This…
