Washington D.C. Ranks #1 in 2019 List of Top 10 Cities with the Best Park Systems

Washington. D.C. has emerged as the top ranking U.S. metropolis in The Trust For Public Land’s 2019 assessment of U.S. cities with the best park system. The non-profit organization performs annual assessments of U.S. city park systems using four metrics: accessibility, acreage, amenities and investment.

 

 

The Trust For Public Land measured accessibility based on the number of city residents who can access the park by way of a 10-minute walk. In terms of amenities, Amenities include popular recreations such as basketball, playgrounds and swimming pools. Amenity-assessments also include recreational facilities for senior citizens, bathrooms and dog parks.

AllTimeList.com helped us compile in brief, important details about each of the top ten cities, based on the metrics used by the organization.

Top Ten U.S. Cities with the Best Park Systems

1. Washington, D.C. – Ninety-eight (98%) of D.C.’s residents are within a 10-minute walking distance to a city park; of which there are as many as has 629 in all. The number represents about 21% of the city land. As of survey period, the city had spent $257 per resident on parks and recreations.

6. Irvine, California – The City of Irvine has 127 parks, dispersed in about 27% of the metropolitan area. They are reachable by way of a 10-minute walk to 80% of the residents. The local government had allocated park-upkeep spending at a rate of of $206 per resident.

7. San Francisco, California – An impressive score of one hundred percent (100%) of San Francisco’s residents can take a 10-minute walk, to easily access one or more of the city’s 471 parks. Parks occupy about 20% of the metropolitan area, for which the city government had spent $260 per resident.

8. Cincinnati, Ohio – Cincinnati’s 259 parks are reachable via 10-minute walk from residents of 77% of the city population. Here, parks occupy about 14% of Cincinnati’s land area, to which the local government incurred costs at a rate of $153 per resident

9. New York, New York – Ninety-nine percent (99%) of New Yorkers can take a 10-minute walk and reach one or more of the city’s 2,311 parks, the largest number enjoyed by city residents. Total area of all parks combined represents 22% of the Big Apple’s jurisdiction, to which the city government allocated a spending rate of only $163 per resident.

10. Chicago, Illinois – Although only 10% of Chicago City’s land is used for parks, a total of 1,230 are located across the metropolis, making recreational and green spaces available by way of a 10-minute walk to 98% of Chicago residents.

Mountain Biking: Incorporating Nature Into Your Exercise

Mountain biking was demonstrated to be among the very best exercise programs on earth. Age doesn’t matter, so long as you’re yare and emotionally able to peregrinate together with the bicycle.

By way of instance, once you’re riding your bike with loads of trees around you out in the hills and slopes going through a multitude of paths, that’s where you’ll discover placidity.  Long and mid-distance runners locate running curative withal, but many people are unable to run. Many can peregrinate using a bicycle, possibly for comfort, or to get the expeditious action it may provide.

You are able to bicycle indoors, known as turning into your heart’s pleasure, or place your mountain bike rollers, particularly during the challenging hiemal months, however you can’t compare the alfresco for new air and liberation. When you ride inside, you’re held to the exact same view.

When you are doing it outdoor with your bicycle, you’ll discover paradise.

The atmosphere is fresh and pristine, at least parks with lots of woods, or maybe you bicycle in places where the topography comprises less vegetation, as is mountainous or desert areas. The result is identically tantamount since new air circulates around you in open locations.

Does this have some therapeutic advantages, besides being a wonderful exercise?

Mountain biking is a game and a physical action considered an aerobic workout, designating that plenty of energy is free. Running is withal an aerobic workout. The whole body functions in unison to maintain your bicycle moving ahead and above obstacles. Your legs are those that get nearly all the cumbersomely heavy-duty to propel the bicycle. Your stomach also receives a fantastic workout. Regular breathing as you ride is essential to maintaining up your stamina. You may additionally get to work out your lungs very marginally. It would be great to avail the best triathlon watch for while you bike, you also monitor how are you doing.

Make mountain biking as secure and stress-free as you can study technique , until it becomes natural for you.  The less anxiety you have when you peregrinate together with all the paths, the greater the rider you will become. On occasion, it is far better to journey less time on the paths and call it off to the afternoon, than to perpetuate exorbitantly fatigued, particularly in the sultry summer season.

Biologists Innovate Bacteria-Based Graphene that Can Handle Large Scale Graphene Productions

Environment-friendly, large scale production of graphene, the innovative nanomaterial essential for the production of computer technologies, medical equipment and other advanced applications, is now possible.

Researchers at the University of Rochester in New York and Delft University of Technology (DUT) in the Netherlands, have found a time-saving and cost-efficient way to produce graphene in large volumes, without causing harm to the environment. More importantly, the new method will ensure that large scale production will not affect the amazing properties of graphene.

In a report published in the ChemOpen Journal, researchers led by Anne S. Meyer, an associate professor at the Department of Biology at the University of Rochester, along with her former colleagues at the DUT in Netherlands, described the new method as one that combines graphite oxidants with bacteria.

Meyer explained that real applications require large amounts. Yet producing bulk amounts of graphene presented difficulties because the resulting substance became denser, and at the same time less pure.

That being one of the stumbling blocks to large-scale graphene production, they were able to tackle the problem by mixing oxidized graphite with bacteria, instead of the present method of using chemicals. Their solution therefore is not only cost efficient and less time-consuming but also environmentally friendly.

Professor Meyer and her team of researchers combined graphene oxidants (GO) with a bacteria known as Shewanella. The bacteria demonstrated capability to remove most of the groups of oxygen, which in time made the GO a highly conductive graphene material. She takes pride in saying that their bacterially-produced graphene is far superior. She added that they were able to develop “bacterial lithography,” a technique that can lead to the development of other nanocomposite materials, using graphene materials that are highly conductive only on one side.

What is Graphene and What Makes Graphene Important

Graphene is best described as a flake of graphite carbon that is equivalent to a single layer of atoms arranged in a pattern resembling a honeycomb. It is actually a nanomaterial, which despite its thinness is regarded as the strongest material with the highest capability for conducting heat and electricity. It was discovered in 2004 by scientists at the University of Manchester in the UK who later received the 2010 Nobel Prize in Physics for its discovery.

Touted as the world’s strongest material, it is widely used in enhancing the strength of other materials like plastic and metals even only with a trace amount of graphene. Composite graphene, possessing greater mechanical strength, high degree of conductivity, and greater capacity for storing energy, found excellent use in the aerospace industry, as well as in the manufacture of construction materials, mobile devices, advanced hospital equipment and many other technological innovations and applications.
