The document summarizes a design project that aims to improve air circulation in buildings. The project proposes installing "Wind-Belt" façades that would use wind-triggered vibration to create electromagnetic induction and drive convection currents, improving airflow. This would help address issues like the urban canyon effect and poor air quality. User experience testing found many still need air conditioning for circulation even in cold weather, and current solutions are inefficient and noisy. The project sees potential markets in air conditioning companies, building owners, and apartment inhabitants, with the goal of providing a cooler, more economical and eco-friendly alternative called "City Breath".

This document summarizes a study that investigated students' alternative conceptions about the water cycle through drawings and interviews. The study involved undergraduate science students with an average age of 21. Students were asked to draw the water cycle and were classified based on the level of understanding shown in their drawings. Individual interviews were then conducted. Common misconceptions identified included thinking the water cycle only involved freezing/melting, only evaporation and condensation, or that water only evaporates from seas and oceans. The scientific understanding of the full water cycle process is also provided.
Open guard edges and edge guards in simple polygons
This document discusses open and closed guard edges in simple polygons. It defines key terms like open guard edges, closed guard edges, and star-shaped polygons. It presents two lemmas: 1) A point p is visible from an open/closed edge depending on the common vertices of paths from p to the edge's endpoints. 2) Given open guard edges ab and cd, their associated paths are disjoint and straight lines. The document proves that a non-starshaped polygon has at most 1 open guard edge and at most 3 closed guard edges. It also shows the intersection of paths associated with closed guard edges is in the polygon's kernel.

The study involved undergraduate science students with an average age of 21. Students were asked to draw the water cycle and were categorized based on the level of understanding shown in their drawings. Individual interviews were then conducted to further understand students' conceptions. The summaries identified several misconceptions students held, including that the water cycle only involves freezing/melting of water, only evaporation and condensation, or only evaporation from seas and oceans. The document concludes by providing the scientifically accurate description of the water cycle.

1. The document describes an experiment on anaerobic respiration using yeast fermentation. Glucose solutions of different concentrations (5%, 10%, 15%) were mixed with yeast and the amount of carbon dioxide produced over time was measured using a carbon dioxide sensor.
2. The results are presented in tables showing the ppm of carbon dioxide detected from each solution over time intervals of 10 seconds for 30 minutes. The highest concentration of glucose (15%) produced the greatest amount of carbon dioxide at each time interval.
3. Graphs of the results show that the amount of carbon dioxide increased over time for each solution, with the rate of production being highest for the 15% glucose solution and lowest for the 5% solution,
Cell division- Mitosis
This study examined biology student teachers' misconceptions about mitosis through drawings and interviews. 124 student teachers participated in the study. They were asked to draw the process of mitosis in a cell. Their drawings were analyzed and categorized into 5 levels of understanding. Interviews were also conducted with 15 students who demonstrated misconceptions. Common misconceptions identified included thinking interphase is the resting phase of mitosis, and that the chromosome number is doubled/halved at different phases of mitosis. The study provides a way to identify misconceptions and address them to improve understanding of cell division concepts.

Dokumen tersebut membahas tentang dualisme dan monisme dalam hubungan antara hukum internasional dan hukum nasional di beberapa negara. Negara-negara seperti Belanda, Jerman, dan Prancis cenderung monisme dengan memberikan prioritas kepada hukum internasional. Sedangkan Inggris dan Amerika Serikat lebih menganut dualisme dengan membedakan hukum internasional dan nasional.
The Chest Coach System
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
Cell division mitosis
This study examined biology student teachers' misconceptions about mitosis through drawings and interviews. 124 student teachers studying to become secondary biology teachers participated. They were asked to draw the process of mitosis in a cell. Drawings were analyzed and categorized into 5 levels of understanding. Individual interviews were also conducted with 15 students who demonstrated misconceptions to validate the drawing interpretations. Common misconceptions identified included thinking interphase is the resting phase of mitosis, the chromosome number doubles in prophase and is halved in anaphase, and that homologous chromosomes separate in anaphase instead of sister chromatids. The study provides examples of student drawings to demonstrate different levels of understanding and misconceptions.

This document discusses the Malaysian Smart School concept and components. It defines the Malaysian Smart School as a learning institution that has been reinvented in its teaching practices and management to prepare students for the Information Age. The key goals of a Smart School are to democratize education, produce a thinking and technology-literate workforce, provide well-rounded student development, enhance individual strengths and abilities, and increase stakeholder participation. It also outlines five strategies for preparing students, including providing a broad curriculum, emphasizing growth in multiple domains, developing technology literacy, accommodating all learning styles, and increasing involvement of all stakeholders.
