The effect of cell phone radiation on yeast (1)
The student conducted an experiment to test the effect of cell phone radiation on yeast metabolism. Yeast and sugar mixtures were placed in test tubes near a cell phone, 30cm away, 1m away, and in another room as a control. The cell phone was used to make calls for 30 minutes by each test tube. Balloon diameters measured the yeast's CO2 output, indicating metabolism. Results showed yeast closest to the phone grew most, while the control grew second most, supporting the hypothesis that closer proximity increases yeast growth due to cell phone radiation. The student learned about cell phone operation and their classification as a potential carcinogen, while gaining experience with the scientific method.

The wackiest cell tower radiation myths
This document discusses and debunks some common myths about cell tower radiation. It presents some outlandish claims people make about health effects of cell towers, such as that cell tower radiation causes sweat glands in ears or can transmit STDs. It then provides facts from scientific organizations like WHO and ICNIRP that no health effects have been proven from cell tower radiation levels and that anti-radiation products are unproven. The document encourages verifying information from credible sources rather than social media.
Photonics
The technology of producing and utilizing light and other types of radiant energy whose quantum unit is the photon. Applications of photonics expand from power generation to recognition of communications and handling of information.
Mr Praveen Jayasuriya Smart Apperal
The document discusses the current state and future potential of smart apparel and wearable technology. It provides background on pioneers in the field and their contributions. Currently, most smart apparel focuses on basic activity and biometric tracking, but opportunities exist in new material sciences, electronic integration techniques, and advanced biochemical and biomechanical sensing to create apparel that can continuously monitor health metrics and provide real-time feedback. Realizing this future will require overcoming challenges in areas like durability, washability, manufacturing processes, and sensor development. The document envisions a future where apparel dynamically adapts to the environment and provides protection, insulation and an interface through changes in appearance and functionality.
Green
This document summarizes evidence on the harmful effects of ultraviolet radiation (UVR) exposure in childhood and epidemiological studies on childhood melanoma. Key points include: 1) Australian children receive 8 times more UV exposure than Danish children and 50% of lifetime UV exposure by age 20; 2) UVR exposure in childhood is linked to increased moles and signs of photoaging; 3) While rare under 20, melanoma incidence is higher in Australia than England for those under 25; and 4) Successful public education campaigns in Australia in the 1980s-90s coincided with decreased melanoma rates in children aged 10-14.
P2 lesson part two
The document provides an overview of a 12-lesson course on radiation and life. It focuses specifically on Lesson 7, which discusses how health studies are conducted to research issues like risks from lifestyles and the health benefits of medicines.

It provides examples of true/false questions and activities to rank risks and understand sample sizes, populations, and independent research.
Magneto impedance sensor
This document provides an overview of a project studying a magnetoimpedance biosensor. The objectives are to detect different types of biomolecular tissues, proteins, and damaged cells using magnetic particles and detecting changes in impedance. Motivation includes low power consumption, fast response time, and high stability. Literature reviewed includes detection of gastric cancer cells using magnetoimpedance. Future work could develop applications to detect tissues not currently detectable. The magnetoimpedance biosensor has potential benefits for society by enabling earlier detection of diseases like cancer to reduce mortality rates.
Vandeventer
This document discusses WHO's research agenda related to children's health and the environment. It focuses on several areas of research including epidemiological cohort studies of RF EMF exposure in children, human provocation studies on RF effects at different ages, and animal studies analyzing prenatal and early life RF exposure. It also outlines WHO recommendations to limit children's exposure to UV radiation from tanning beds and the IARC classification of UV as carcinogenic to humans. The purpose of WHO's research agenda is to promote studies that can reduce scientific uncertainties around health effects and better inform risk communication through social science research.
Wiart
The document discusses numerical dosimetry related to radio frequency (RF) exposure in children from wireless communication systems such as mobile phones.
It notes that realistic 3D numerical models of children's bodies and heads are needed to properly assess exposure, as a child's anatomy changes significantly with age and is not simply a smaller version of an adult. Factors like morphology, tissue properties, and phone usage also influence exposure.
While current safety limits may be conservative, localized exposure of tissues near the surface of a child's brain could potentially be higher than in an adult. Further research is ongoing to better understand children's RF exposure.

The document discusses the dangers of electromagnetic radiation exposure from wireless technologies like cell phones, WiFi, and baby monitors. It notes that scientific evidence points to increased brain tumor risk after 10 years of cell phone use. Exposure to wireless radiation is considered biologically active and studies have found cumulative effects from repeated exposure. The risks are greater for children due to their developing bodies and thinner skull bones that allow for deeper radiation penetration. The document urges parents to take action to protect their children from these risks.What is photonics - PDplus at RiAus

Silicon Photonics 2014 Report by Yole Developpement
Beyond all of the hype and tumult, market drivers and technological developments are converging to ensure a bright future for Si photonics.
THOUGH THE SI PHOTONICS MARKET HAS JUST KICKED OFF, VOLUME PRODUCTION IS ALREADY CLOSE
Big data is getting bigger by the second, and transporting it with existing technologies will push the limits of power consumption, density and weight. Yole Développement analysts are convinced that photons will replace electrons, and that Si photonics will be the mid-term platform to assist this transition.
Si photonics offers the advantages of silicon technology: low cost, higher integration, more embedded functionalities and higher interconnect density. It also provides two other key advantages:
1. Low power consumption: particularly when compared to copper-based solutions, which are expensive and require high electrical consumption.
2. Reliability: especially important for data centers, where a typical rack server’s lifespan is two years before replacement.
Back in 2006, VOA were the market’s first Si photonics products. Today, there are still a few Si photonics products on the market (i.e. VOA, AOC and transceivers from Luxtera, Kotura/Mellanox and Cisco/Lightwire) but big companies (i.e. Intel, HP and IBM) are close to realizing silicon photonics products. Yole Développement also sees big OEMs such as Facebook, Google and Amazon developing their own optical data center technology in partnership with chip firms (such as Facebook with Intel).
In this report Yole Développement shows that, in the short-term, silicon photonics will be the platform solution for future high-power, high-bandwidth data centers. Silicon photonics chips will be deployed in high-speed signal transmission systems, which greatly exceed copper cabling’s capabilities, i.e. for data centers and high-performance computing (HPC). As silicon photonics evolves and chips become more sophisticated, we expect the technology to be used more often in processing tasks such as interconnecting multiple cores within processor chips to boost access to shared cache and busses.
Analysts also analyzed silicon photonics’ chances of being used for telecom, consumer, medical and biosensors applications, compared with competing technologies.

Optical fiber communiction
Optical fibers use total internal reflection to transmit light signals for communication. They have a core and cladding layer, with the core having a higher refractive index to contain the light. Key components of an optical communication system include an information source, transmitter, fiber cable, receiver, and destination. Optical fiber networks have widespread applications in telecommunications, medicine, military systems, and more due to advantages like high bandwidth, low attenuation, immunity to electromagnetic interference, and signal security.
Seminar on CCTV Cameras
CCTV systems use video cameras to transmit signals to a limited set of monitors for security purposes rather than broadcasting publicly. Modern CCTV cameras employ closed-circuit television technology. The first CCTV security system was installed in 1942 in Germany, while digital and wireless CCTV cameras were later developments. CCTV cameras can be indoor, outdoor, hidden, dome-shaped, or have pan-tilt-zoom functions. Systems are either wired using coaxial cables or wireless using radio transmitters. CCTV provides security benefits but also raises privacy concerns.
