Newton's Laws, G-Forces and the Impact on the Brain Zasady
The Journal of Neurological and Neurosurgical Nursing 2019;8(3):133–137 Pielęgniarstwo Neurologiczne i Neurochirurgiczne THE JOURNAL OF NEUROLOGICAL AND NEUROSURGICAL NURSING /JNNN 2019;8(3):133–137 2019;8(3):133–137 eISSN 2299-0321 ISSN 2084-8021 www.jnnn.pl Review DOI: 10.15225/PNN.2019.8.3.6 Newton’s Laws, G-forces and the Impact on the Brain Zasady Newtona, siła grawitacyjna a ich wpływ na mózg Vicki Evans Royal North Shore Hospital, Sydney, Australia Abstract The thrill to go fast and push boundaries is something that many seek. From John Stapp’s rocket sled at Edwards Air Force Base in the late 1950’s to todays’ Formula 1 drivers, the “need for speed” is broadcast across TV screens weekly. So too are the horror stories of crashes, many at over 300 km/hr. Yet “need for speed” continues. It appears that the higher and faster the rollercoaster, the better. This leads to several questions. How does the brain stand up to speed and G-forces? Do Newton’s Laws still have reference in today’s world? There has been much attention in the general press on the possibility that high G-force roller-coasters are inducing brain injury in riders. However, research does not wholeheartedly support this notion, but rather the risk of brain injury from a rollercoaster is not in the rides, but in the rider — caused by previously undetected brain or neck conditions. That said there is some truth that high G-forces do affect the brain at a chemical and structural level. -
2. Díl – Tryskový Muž Aneb Jaké Je to Létat Jako Pták Poměrně Náročnou Otázkou Pro Mě Bylo, Kterým Zajímavým Projektem Nebo Rekordem Začít
2. díl – Tryskový muž aneb jaké je to létat jako pták Poměrně náročnou otázkou pro mě bylo, kterým zajímavým projektem nebo rekordem začít. Vybírat je opravdu z čeho, protože svět letectví se žene kupředu závratným tempem, takže se ukázalo, že potíží není najít něco, o čem psát, ale naopak vybrat z ohromného množství to, čím začít. Po opravdu náročném rozmýšlení jsem nakonec dospěl k rozhodnutí, že seriál začnu představením toho, co v té nejčistší formě naplňuje odvěkou lidskou touhu létat. Jinak řečeno, začnu hned pěkně zostra. Let ptáků člověka inspiroval odedávna. Důkazy o tom nám poskytují již nejrůznější staré mýty. V průběhu staletí se objevovali vynálezci, kteří navrhovali létajicí aparáty, tu s větším, tu s menším úspěchem. Až konečně bratři Wrightové vstoupili na tu správnou cestu. Jejich následovníci po celém světě zkonstruovali ohromné množství letadel a létajicích zařízení. Žádné z nich však zcela nenaplňovalo onu odvěkou představu o letu, jakým se vyznačují ptáci. Ať už proto, že se člověk vzduchem pohyboval v kovovém obalu, pevně přikurtován k sedačce, jak je tomu v případě letadel, nebo proto, že i když se vzduchem proháněl podobně jako pták, bez nějakých vnějších schránek, bylo to naneštěstí vždy jen jedním směrem, jak by si mohli parašutisté postesknout. Pro dosažení naprosté svobody létání, jak ji zažívají ptáci, by se tedy měly oba tyto přístupy zkombinovat. Zachovat na jedné straně svobodu parašutisty, ale na druhé straně ji doplnit o schopnost plně řídit svůj let, jak jsme na to zvyklí u letadel. Tohoto zadání se chytil švýcarský pilot a dobrodruh – Yves Rossy, známý taktéž jako Jetman, Tryskový muž. -

Yves “Jetman” Rossy
Yves “JetMan” Rossy “When I grow up, I’m going to be pilots. With an S”. A profession of faith made as a child that was instilled in Yves Rossy the day he found himself on the branch of a tree unable to get down unaided. Today, he has become Jetman, the first man in the world to attach jet engines to a single wing and fly like Icarus. His story. Yves Rossy was born on the 27 of August 1959 in Neuchâtel (Switzerland). With his head in the clouds and his feet on the ground, Yves Rossy followed a technical apprenticeship and then graduated in engineering. An accomplished sportsman, his past and present pastimes include surfing, water-skiing, wakeboarding, skysurfing, parachuting, aerobatics, motorbike riding, rafting and hang-gliding, to name but a few. Flying under a jet wing is the culmination of a 30 year career interspersed with exploits and firsts. Fighter pilot Discovering the Mirage III supersonic fighter plane was certainly one of the high points of Yves Rossy’s career. He flew the aircraft for 17 years while at the same time piloting historic aircraft such as the Hunter and the Venom, one of England’s earliest jet fighters. In 1991 the idea arose to complete a multi-activity tour of Switzerland in a single day. On 3 July that year he began the day at the controls of a DC-9 and completed the challenge by riding a motorbike, snowboarding, skiing, mountaineering, paragliding, mountain biking, bungee-jumping, flying a helicopter, skydiving and white water rafting, followed by kayaking, driving a racing car, hanggliding, horse riding, running barefoot, water-skiing, wakeboarding and piloting a speed boat. -

By pursuing research relating to the medical aspects of flight, USAFSAM has provided pilots and astronauts with the necessary equipment and support to ensure their overall safety and health. In 1926, Brooks Field began its first association with the School of Aviation Medicine (SAM) when it moved from New York in order to support the Primary Flying School at Brooks Field. While stationed there from 1926 to 1931, the school trained flight surgeons as well as performed cadet physical examinations. SAM's brief but important tenure at Brooks Field served as a vital step in the development of aviation medicine and its contributions to pilot safety and training. In 1959, SAM again was relocated to Brooks AFB as part of an Air Force plan to concentrate its aerospace medical research facilities at one location. -

With a subjective camera shooting, Marianne Chaud, a young ethnologist, grants us a sensitive and poetical immersion in the universe of four generations of women during the harvest in Zanskar. We share their everyday lives, waiting a husband with the first, being bored and lonesome with the second one, giving a tender look to the kids' games with the following and sharing with the older one her very dying days.

After wandering aroung the world for ages, international scientists involved in a large variety of disciplines have arrived at the same conclusion that we know nothing or next to nothing in Europe of the world we are living in. They, thus, engaged in a mission: decypher and understand the biodiversity concealed in an apparently ordinary forest. Such an expedition had never been led in any european forest.
