Diet Coke and Mentos Eruption
A Diet Coke and Mentos eruption (also known as a soda geyser) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to spray out of its container. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle. Lee Marek and "Marek's Kid Scientists" were the first to publicly demonstrate the experiment on the Late Show with David Letterman in 1999. Steve Spangler's televised demonstration of the eruption in 2005 became popular on YouTube, launching a chain of several other Diet Coke and Mentos experiment viral videos.

Dhyāna Sutras
The Dhyāna sutras (Chinese: 禪経) or "meditation summaries" (Chinese: 禪要) are a group of early Buddhist meditation texts which are mostly based on the Yogacara[note 1] meditation teachings of the Sarvāstivāda school of Kashmir circa 1st-4th centuries CE. Most of the texts only survive in Chinese and were key works in the development of the Buddhist meditation practices of Chinese Buddhism.

Dhyāna in Buddhism
In the oldest texts of Buddhism, dhyāna (Sanskrit) or jhāna (Pāḷi) is the training of the mind, commonly translated as meditation, to withdraw the mind from the automatic responses to sense-impressions, and leading to a "state of perfect equanimity and awareness (upekkhā-sati-parisuddhi)." Dhyāna may have been the core practice of pre-sectarian Buddhism, in combination with several related practices which together lead to perfected mindfulness and detachment, and are fully realized with the practice of dhyana. In the later commentarial tradition, which has survived in present-day Theravāda, dhyāna is equated with "concentration," a state of one-pointed absorption in which there is a diminished awareness of the surroundings. In the contemporary Theravāda-based Vipassana movement, this absorbed state of mind is regarded as unnecessary and even non-beneficial for awakening, which has to be reached by mindfulness of the body and vipassanā (insight into impermanence). Since the 1980s, scholars and practitioners have started to question this equation, arguing for a more comprehensive and integrated understanding and approach, based on the oldest descriptions of dhyāna in the suttas. In Chán and Zen, the names of which Buddhist traditions are the Chinese and Japanese pronunciations, respectively, of dhyāna, dhyāna is the central practice, which is ultimately based on Sarvastivāda meditation practices, and has been transmitted since the beginning of the Common Era.

Dhammakaya Meditation
Dhammakaya meditation is a method of Buddhist meditation developed and taught by the Thai meditation teacher Luang Pu Sodh Candasaro (1885–1959).[note 1] In Thailand, it is known as vijjā dhammakāya, which translates as 'knowledge of the body of truth'. It is the meditation tradition that is at the center of the Dhammakaya Movement. The Dhammakaya meditation method has become very popular in Thailand and other parts of Southeast Asia, and has been described as a revival of samatha (tranquility) meditation in Thailand. The method was discovered by Luang Pu Sodh in the 1910s. Followers of the Dhammakaya Movement believe the method was the same as the original method the Buddha used to attain enlightenment. According to Luang Pu Sodh, the Dhammakāya, the core concept of the tradition, can be found within every human being. The most important aspect of the meditation method is the focus on the center of the body. As of 2008, there was still scholarly debate as to the origins of Dhammakaya meditation. Scholars refer to the Yogavacara tradition as a possible source, or that the method might be new or partly new. Dhammakaya meditation is taught at several temples of the movement, and consists of a stage of samatha (tranquility) and vipassana (insight), following the structure of the Visuddhimagga, a standard fifth-century Theravāda guide about meditation. In the method, the stages are described in terms of inner bodies (Pali: kāya), but also in terms of meditative absorptions (Pali: jhānas). Dhammakaya meditation has been the subject of considerable discussion among Buddhists as to its authenticity and efficacy, and also has been the subject of several scientific studies.

Devil in Christianity
The Devil in Christianity is the personification of evil and author of sin, who rebelled against God in an attempt to become equal to God himself.[lower-alpha 1] He is depicted as a fallen angel, who was expelled from Heaven at the beginning of time, before God created the material world, and is in constant opposition to God. The devil is identified with several figures in the Bible including the serpent in the Garden of Eden, Lucifer, Satan, the tempter of the Gospels, Leviathan, and the dragon in the Book of Revelation. Early scholars discussed the role of the devil. Scholars influenced by neoplatonic cosmology, like Origen and Pseudo-Dionysius, portrayed the devil as representing deficiency and emptiness, the entity most remote from the divine. According to Augustine of Hippo the realm of the devil is not nothingness, but an inferior realm standing in opposition to God. The standard Medieval depiction of the devil was set up by Gregory the Great. He integrated the devil, as the first creation of God, into the Christian angelic hierarchy as the highest of the angels (either a cherub or a seraph). But as high as he stood in heaven, so far he fell into the depths of hell and became the leader of demons. Since the early reformation period, the devil was imagined as an increasingly powerful entity, with not only a lack of goodness but also a conscious will against God, his word, and his creation. Simultaneously, some reformists interpreted the devil as a mere metaphor for human's inclination to sin and so downgraded the importance of the devil. While the devil played for most scholars no significant role in the Modern Era, he became more important in contemporary Christianity again. At various times in history, some people such as the Cathars and the Bogomiles, as well as theologians like Marcion and Valentinus, believed that the devil was involved in creating the world. Today these views are not part of mainstream Christianity.

Development of Data Driven Smart Cities
Cities are investing in data-driven smart technologies to improve performance and efficiency and to generate a vast amount of data. Finding the opportunities to innovatively use this data help governments and authorities to forecast, respond, and plan for future scenarios. Access to real-time data and information can provide effective services that improve productivity, resulting in environmental, social, and economic benefits. It also assists in the decision-making process and provides opportunities for community engagement and participation by improving digital literacy and culture. Smart people, smart living, and smart governance methods that have come into practice at a later stage are as important as smart mobility, smart environments, and smart economy measures that were implemented early on, and cities are opening up to new, transparent participatory governance approaches where citizens play a key role. It also illustrates that the current new wave of smart cities with real time data are promoting citizen participation focusing on human, social capital as an essential component in future cities.

Developing Indoor Temperature Profiles of Albanian Homes
Oversimplifying occupant behaviour using static and standard schedules has been identified as a limitation of building energy simulation tools. Three statistically different profiles were developed for each summer and winter, indicating that homes are used in different ways, as well as revealing possible comfort requirements. A statistically significant association was found between the presence of children and the clusters in winter, suggesting that families with dependents use more energy. Building-related factors including building type, building age, and wall insulation were found to be statistically significantly associated with clusters in summer.
