Therefore, this installation is looking at the world on an equal point of view instead looking at it on an equity point of view. Like equity see work of Elena Kovylina in St. Moreover, an other issue with this installation is that harmony is difficult to define — it is not only fast and slow — and can be seen differently depending on the individual.

At this stage, these observations raise the following question: There is urgency to act and fast according the scientific community Gore, Ecosystems — the complex interdependent webs of living organisms and natural resources — play a critical role in supporting human wellbeing and driving economic growth through the valuable services they provide such as food, water for drinking and irrigation, pollination and climate regulation.

Yet human society has systematically undermined these natural allies, treating forests, arable land and rivers as though they are inexhaustible United Nations Environment Programme, The issue is that these resources are not infinite as highlighted previously, but are still essential for our survival.

Circadian Biology and its advantages.

From these considerations I started to search for a design solution to make individuals act for the better good of the planet. I started questioning what are the possible actions and when there would be time to achieve them, or at least think about the issues.

To find these moments I conducted two different studies. Like taxi driver, lollypops lady… and lifeguard. I decided to focus on Lifeguard, as I have been one for 8 years.

It consists of spending hours waiting: The question I am asking from these observations is: As the Lifeguard do, should we all keep an eye, not on people swimming, but on the planet and prevent disaster?

And how to get people to watch and prevent the disaster in every day life? To get answers I sent a questionnaire to 5 of my colleagues in France.

Soon we will see ‘chrono-’ attached to every form of medicine | Aeon Essays

The questions are around the way they invigilate the swimming pool, how they manage to stay focussed, and how they detect that something bad could happen.

Finally I asked if they needed a tool or an invention to help them to do a better job. In the answers I had, they insist a lot on the observation and prevention.

They believe that concentration comes with experience and you develop the ability to detect problem before they arrive, developing a 6th sense in time. To do the job well they recommend to move, be in action, fight against monotony. Prevention is their key word.

As suggestion to improve the surveillance they would like to instal camera under the water, give a better education to the people, and a good one is create bionics ears to detect calls for help.In cyanobacteria, circadian clocks regulate nitrogen fixation.

In general, circadian clocks direct cell replication, amino acid uptake, and carbohydrate synthesis. Why are circadian clocks important? Circadian clocks are an integral part of everyday life for most all organisms on Earth.

They regulate the most important functions in each organism.

Specific circadian genes such as CLOCK, BMAL1, and PER are responsible for the main SCN clockworking machinery as well as subsidiary clocks in other parts of the body. In mice with mutations in time-keeping genes, deviant circadian sleep-wake and other rhythms can be observed. The effects of circadian dysfunction can be disastrous in the long term – knock out the cellular clocks in just part of a mouse pancreas, for example, and diabetes quickly ensues.

W e can time everything from exercise and eating to work and thinking for maximum effectiveness. Michel Siffre spent 6 months in a cave without external cues and found his circadian rhythm varied from hours again highlighting the existence of an internal circadian clock.

This also highlighted the importance of exogenous zeitgebers in regulating internal biological clocks.

This also highlighted the importance of exogenous zeitgebers in regulating internal biological clocks. The circadian rhythm is the pattern of fluctuations in bodily processes that occur regularly each day. Circadian rhythms are found in mostly all species. These rhythms are synchronized with the 24 hour cycle of day and night. In humans, the sleep-wake cycle operates on a circadian rhythm that is 3/5(3). Circadian Rhythms Essay. Circadian Rhythms. Ever wonder why people sleep at night and work during the day? - Circadian Rhythms Essay introduction?? Why do people feel sleepy when darkness falls? These questions can be answered by understanding the concept of circadian rhythms.

It's also known as your sleep/wake cycle. Circadian Clocks Essay example - What is a circadian clock.
