The document summarizes the key functions and components of the respiratory system. It begins with an overview of how air moves from the nose or mouth through the trachea and bronchi into the lungs. It then provides 10 interesting facts about respiration and the lungs. The document concludes with sections on lung cancer symptoms, prevention strategies, and diagrams of the trachea and lungs.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

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.

The Respiratory System
1. R e s p i r a t o r y s y s t e m By Wheturangi Derby Year 9, Paeroa College New Zealand
2.
3. First the body breathes in the air which is sucked through the nose or mouth and down through the trachea (windpipe). The trachea is a pipe shaped by rings of cartilage. It divides into two tubes called bronchi. These carry air into each lung. respiratory uses
4.
5. 6,We lose about a half a litre of water a day from breathing. 7,The surface area of people’s lungs is as big as a tennis court. 8.The capillaries in the lungs would extend 1,600 kilometres if placed end to end 9.Inside the lung, the tubes divide into smaller and smaller tubes called bronchioles. 10.At the end of each of these tubes are small air balloons called alveoli.
6.
7. Were you focusing 3. What happens to air when passed through the hairs in your nose? A] It gets warmed up and cleaned B] It gets cooled down C] None of the above 4. How many times does someone breathe a minute while they are asleep? A] 23-30 B] 18-20 C] 16-17 D] 12-15
8. Were you paying attention ? 5. What is the highest speed recorded for a sneeze travelling? A] 120km/h B] 145km/h C] 150km/h D] 165km/h 6. Around about how many litres of water do we lose a day from breathing? A] 3/4 litres B] ½ litres C] 2 litres D] 5 litres
9. 7. How big is the area of someone’s lung? A] As big as a netball court B] As big as a rugby field C] As big as a tennis court 8. How long would the capillaries in the lungs extend to? A] 1,200 kilometres B] 1,400 kilometres C] 1,600 kilometres Almost there……………
10. 9. The lungs have tubes that divide into smaller and smaller tubes called what? A] Capillaries B] Lung tubes C] Bronchioles 10. At the end of these tubes there are small air balloons called what? A] Lung balloons B] Bronchioles C] Alveoli Last few questions ……
11. The trachea…… The Trachea The Trachea also known as the wind pipe is used to pass air that is breathed in through the nose or mouth into the lungs. The diagram below shows the Trachea.
12. The Lungs……. The lungs are two vital organs in the respiratory system Air is breathed in and the trachea pumps the oxygen that goes into the lungs and carbon dioxide goes out. The lungs are also shown on the diagram below
13. Lung cancer Symptoms of lung cancer are varied depending upon where and how widespread the tumour is. Warning signs of lung cancer are not always present or easy to identify. A person with lung cancer may have the following kinds of symptoms 1.Swelling in the throat. 2.Change from your normal cough. 3.A hoarse voice. 4.You loss weight easily. 5.You loose your hunger for food. 6.You may notice blood in your phlegm. 7.You get sore when breathing or coughing. And much more.
14. How to prevent lung cancer You should go in for checks every now and then if it is common in your family or if you have any of the symptoms of it. Another way to prevent it is not to smoke or be around smokers. If you have been diagnosed with lung cancer, be sure to follow your doctor's instructions about calling when you have problems, new symptoms, or symptoms that get worse.
