Sustainable energy is energy that is created in an environmentally friendly way.
It involves both energy efficiency and renewable energy. Both resources help to stabilize and reduce carbon dioxide emissions.
Efficient energy use allows energy demand to slow so that rising clean energy supplies can make big cuts in fossil fuel burning. If energy use grows too fast, renewable energy development will chase a receding target. Likewise, unless clean energy supplies come online rapidly, slowing demand growth will only begin to reduce total emissions; reducing the carbon content of energy sources is also needed.
Any serious vision of a sustainable energy economy thus requires major commitments to both efficiency and renewables.
Neoprene
Neoprene is the DuPont Performance Elastomers trade name for a family of synthetic rubbers based on polychloroprene (polymer form of Chloroprene). Neoprene was invented by DuPont scientists after Dr. Elmer K. Bolton of DuPont attended a lecture by Fr Julius Arthur Nieuwland, a professor of chemistry at the University of Notre Dame.
It is used in a wide variety of environments, such as in wetsuits, laptop sleeves, cars, bombs, electrical insulation, and car fan belts. Its chemical inertness makes it well suited for industrial applications such as gaskets, hoses, and corrosion-resistant coatings. It can also be used as a base for adhesives.
Pioneer 11
Pioneer 11 (also known as Pioneer G) was the second mission to visit Jupiter and the first mission to visit Saturn. The spacecraft was launched on April 6, 1973 and flew by Jupiter on December 4, 1974 and Saturn on September 1, 1979. The probe was last heard from November 1995 when the last communication between Earth and the probe ended due to power limitation and vast diatance.
Both Pioneer 10 and Pioneer 11 had plaques etched in gold. The plaques were designed by a team lead by Carl Sagan to communicate with extraterrestrial life should the spacecraft come into contact with it.
Medical tourism
Medical Tourism is when patients visit other countries for medical care. The patients usually come from developed countries to find treatment at lower prices. Over 50 countries have identified medical tourism as a national industry.
Examples of common medical procedures done for medical tourists are surgeries like joint replacement, heart surgery, cosmetic surgery, dental treatment, and addictions rehabilitation (or recovery from addiction).
The term "medical tourism" can also be called medical travel, health tourism or global healthcare. it was initially developed by travel agencies and the mass media to describe the rapidly-growing practice of travelling across international borders to obtain health care.mainly it is for curing people and a lot of countries believe on this.
Countries that are popular for Medical Tourism are:
To get an idea of the potential cost savings from medical tourism, in Denver, Colorado, USA, a person without health insurance who needs a hip replacement will pay about US $60,000 (EUR 44751). In comparison, in Cuba, going through medical tourism firm Choice Medical Services, the same procedure costs about US $8000 (EUR 5967) or about an 80 percent savings.
Burrowing parakeet
The burrowing parakeet ("Cyanoliseus patagonus"), also known as the burrowing parakeet or Patagonian conure, is a species of parrot in the Psittacidae family. It is found in Argentina, Chile, Falkland Islands, South Georgia and the South Sandwich Islands, and Uruguay. It lives in subtropical or tropical dry shrubland, subtropical or tropical high-altitude shrubland, and pastureland. It is also known as the burrowing parrot.
Aquifer
An aquifer is an underground layer where the material contains water. That can be less solid material like sand, gravel, clay or silt, but it can be rock as well, as long as the rock allows water to get in (that means that it is water-bearing).
From such layers or groundwater can be usefully extracted using a well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.
Groundwater may exist in underground rivers (e.g., caves where water flows freely underground). This may occur in eroded limestone areas known as karst topography, which make up only a small percentage of Earth's area. More usual is that the pore spaces of rocks in the subsurface are simply saturated with water — like a kitchen sponge — which can be pumped out for agricultural, industrial, or municipal uses.
If a rock unit of low porosity is highly fractured, it can make a good aquifer (via fissure flow), if the water can get through it. Porosity is important, but, "alone", it does not make an aquifer. The Deccan Traps (a flood basaltic lava) in west central India are good examples of rock with high porosity but low permeability, so they are poor aquifers. The (Upper Cretaceous) Chalk of south east England has a reasonably high porosity, but low grain-to-grain permeability. Much of its good water-yielding characteristics being due to micro-fracturing and fissuring.
Aquifers can occur at various depths. Those closer to the surface are not only more likely to be exploited for water supply and irrigation, but are also more likely to be topped up by the local rainfall. Many desert areas have limestone hills or mountains within them or close to them which can be exploited as groundwater resources. If more water is taken out than get in again one speaks of over-harvesting. Along the coastlines of certain countries, such as Libya and Israel, population growth has led to over-population which has caused the lowering of water table and the subsequent contamination of the groundwater with saltwater from the sea (saline intrusions). In these cases the aquifer contains brackish water.
When water seeps (comes slowly) out of the ground, it is called a seep or "spring (water)". It usually means there is an aquifer under the ground.

AFI is an acronym that can mean:
Voyager 2
Voyager 2 is a spacecraft used by NASA to explore Jupiter, Saturn, Uranus, and Neptune. It is the only spacecraft that has come near to Uranus and Neptune. Because of this, a majority of pictures we see of these two ice planets came from this spacecraft. It was identical in form to its sister ship, "Voyager 1". The probe is currently moving away from the solar system, and is heading out into interstellar space.
"Voyager 2" was launched on August 20, 1977.
Both "Voyager 1" and "Voyager 2" include the Voyager Golden Record, which is a recording of sounds and images of life on Earth. It was designed by a team headed by Carl Sagan to communicate with extraterrestrial life.
In 2018, NASA announced that Voyager 2 had reached the heliopause on 5 November of that year.
World Party Day
World Party Day (P-Day) is celebrated on April 3 as a synchronized global mass celebration of a better world and the creation of desirable reality.
The idea of a coordinated synchronized worldwide party appeared as a work of fiction in the book "Flight, A Quantum Fiction Novel", by American writer Vanna Bonta. In the ending of the book, published in 1995, all people in the world celebrated at the same time.
Masses of people grew larger by connecting with groups who shared ideals of peace and goals of using human intelligence and resources toward humanitarian progress.
A massive worldwide phenomenon now in progress involves millions of individuals, organizations and corporations around the world who are realizing a responsibility and ability to contribute positively to the collective future of humanity and Earth.
The internet, media and communication has accelerated one of the biggest social transformations in human history, facilitating the organization of global movements. Research has begun documenting the emerging social transformation of people around the world uniting for a positive, joyful future for humanity, through a common task.
