Ultraviolet radiation lies between visible light and x-rays on the electromagnetic spectrum. It is emitted by the sun and tanning beds. While UV radiation produces vitamin D, overexposure presents health risks like sunburn, skin cancer, and eye damage. The main sources of overexposure are the sun and tanning beds. Tanning beds use UV radiation to artificially induce tanning by simulating sunlight.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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.
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.
3. 1. DEFINE ULTRAVIOLET RADIATION
Ultraviolet (UV) radiation is a form of non-
ionizing radiation that is emitted by the sun
and artificial sources, such as tanning beds.
The beneficial effects of UV radiation
include the production of vital nutrient,
vitamin D; however overexposure may
present risk.
4. 2. DESCRIBE WHERE
ULTRAVIOLET
RADIATION IS
FOUND ON THE
EMS COMPARED TO
THE OTHER SIX
FORMS OF
RADIATION.
Ultraviolet radiation lies
between visible light and
x-rays along the
electromagnetic
spectrum. UV “light”
spans a range of
wavelengths between
about 10 and 400
nanometers, while the
wavelength of violet light
is around 400
nanometers or (4,000 Å).
5. 3. ARE THERE HUMAN HEALTH RISKS
FROM EXPOSURE (OR OVEREXPOSURE)
TO ULTRAVIOLET RADIATION?
YES! There are health risks associated with
exposure or overexposure to ultraviolet (UV)
radiation.
6. • DESCRIBE THE MAIN RISK(S)
•Sunburn •Skin Cancer •Eye Damage
7. • Sunburn – UVB radiation is primarily responsible for sunburn, which is
characterized by red, painful, and inflamed skin. Severe sunburn can
cause blistering, peeling, and increase of the risk of skin cancer.
• Skin Cancer – prolonged exposure to UV radiation, especially UVA and
UVB, increases the risk of developing skin cancer. This includes both
non-melanoma skin cancers and melanoma, which is the most
dangerous skin cancers.
• Eye Damage – UV radiation can also harm the eyes. Overexposure to
UV radiation increases the risk of cataracts, a clouding of the eye’s
lens that can impair vision. It can also cause photo keratitis, a painful
condition similar to sunburn of the cornea.
•DESCRIBE COMMON SOURCES OF
EXPOSURE OR OVEREXPOSURE
8. • TO PROTECT YOURSELF FROM
THE HARMFUL EFFECTS OF UV
RADIATION:
• Use Sunscreen
• Wear Protective
Clothing
• Seek Shade
• Avoid Tanning Beds
9. 4. DESCRIBE HOW
ULTRAVIOLET RADIATION IS
USED IN TANNING BED
TECHNOLOGY
Tanning beds, also known as
sunbeds or indoor tanning devices,
use ultraviolet (UV) radiation to
simulate sunlight on the skin. The
technology behind tanning beds
involves the controlled emission of
UV radiation to induce a tan.
