In Greek mythology, Antigone is the daughter of Oedipus and his mother, Jocasta. The denotement of the designation is, as in the case of the masculine equipollent Antigonus, "worthy of one's parents" or "in lieu of one's parents".
The authors utilize a fable about a penguin colony in Antarctica that has lived on the same iceberg for many years. When one curious bird discovers quandary signs in the iceberg, few penguins want to heedfully auricularly discern him. They are fine the way things are and don't optate to transmute. The story is analogous to the prevalent situation where people don't optate to face up to conundrums at home or at work.
Once a diminutive group of penguins came to understand that their iceberg authentically was melting, they 1) engendered a sense of exigency in the colony to deal with the arduous problem, 2) put a punctiliously culled group in charge of guiding the vicissitude, 3) found the sensible vision of a better future, 4) communicated that vision so others would understand and accept it, 5) abstracted as many obstacles to action as was practical, 6) created some remotely prosperity expeditiously, 7) never let up until the incipient way of life was firmly established, and, 8) conclusively, ascertained that the vicissitudes would not be overcome by adamant, hard-to-die traditions.
Blood will not break up unless it is acted upon perforce. The force must be great enough to surmount the surface tension of the blood Blood forms a spherical shape (perfect circular shape) virtually immediately upon dissevering from the blood source. The spherical shape is caused by the surface tension of the blood. Surface Tension causes the blood drop to pull itself in; both horizontally and vertically. The blood drop will settle into a spherical shape, as a result of the surface tension.The surface tension will maintain the sphere shape of the blood drop until it impacts with the
surface.
Blood is a bodily fluid in animals that distributes obligatory substances such as nutrients and oxygen to the cells and conveys metabolic waste products away from those same cells.When it reaches the lungs, gas exchange occurs when carbon dioxide is diffused out of the blood into the pulmonary alveoli and oxygen is diffused into the blood. This oxygenated blood is pumped to the left hand side of the heart in the pulmonary vein and enters the left atrium. From here it passes through the mitral valve, through the ventricle and taken all around the body by the aorta. Blood contains antibodies, nutrients, oxygen and much more to avail the body work.
Forensic Pathology is a sub-specialty of pathology that focuses on determining the cause of death by examining a corpse. The autopsy is performed by a medical examiner, usually during the investigation of criminal law cases and civil law cases in some jurisdictions. Coroners and medical examiners are also frequently asked to confirm the identity of a corpse.

In microeconomics, supply and demand is an economic model of price determination in a market. It concludes that in a competitive market, the unit price for a particular good will vary until it settles at a point where the quantity demanded by consumers will equal the quantity supplied by producers, resulting in an economic equilibrium for price and quantity.
Woman wilt not accept; she wilt challengeth. she wilt not be aw'd by that which hath been built up around h'r; she wilt rev'rence that woman in h'r which struggles f'r expression. The sooth will seteth thou free. But first, it will piss thou off. the people we art in relationship with art always a mirr'r, reflecting our owneth beliefs, and simultaneously we art mirr'rs, reflecting their beliefs. so. . . relationship is one of the most pow'rful tools f'r growth. . . . if we looketh honestly at our relationships, we can seeth so much about how we hast creat'd them.
This chapter builds on a brief introduction in the previous chapter by providing a more detailed analysis of product demand. The chapter covers demand functions and demand curves. It introduces elasticities and the properties of linear demand curves. The relation between total revenue and price is examined. The chapter also provides a brief introduction to network effects, the product-attribute model, product life cycles, and demand estimation. An appendix covers point elasticities, marginal revenue for linear demand curves, and log-linear demand curves.

Hallucinogens are drugs taken recreationally to alter thoughts, perceptions and emotions. The hallucinogens, more commonly known as psychedelics, produce visual, auditory and other sensory hallucinations--experiences that are not real.
Euphoria may occur, but these drugs also commonly cause agitation, confusion, anxiety, paranoia, delusions, loss of social inhibitions, and wildly labile emotions.
Large doses of hallucinogens can cause psychosis, ruptured brain blood vessels, brain damage, seizures, and potentially fatal respiratory and heart failure. According to the 2008 National Survey on Drug Use and Health, approximately 1.1 million Americans use hallucinogenic drugs.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
