First Container Ship Crossing the Northern Passage

For the past few years, the Arctic has been sufficiently ice-free in the summertime that some ships have been able to take the short-cut routes across the cialis low priced North Sea Route and canadian cialis and healthcare the Northwest Passage. Last year, among others, a small sailboat with a crew of 3 made the Northwest Passage. This year, a 19,000 ton Chinese cargo container carrier is traveling to Amsterdam via the Arctic, going north and traveling along the northern coast of Russia, rather than down through the Indian Ocean and through the Suez Canal and the Mediterranean. This marks the first time that a container ship is buying cialis traveling through the Arctic.

The shorter trip will mean lower fuel costs (and, ironically, fewer greenhouse gas emissions) for the www.velikibrat.us freighter. Taking this route is expected to save 12 to 15 days of travel and shortens the trip by roughly 7,000 kilometers (4,350 miles).

While this is news now, it is all too likely that this will go from a unique occurrence to http://www.investordaily.com.au/get-cialis an ordinary annual event within a few years.

Fukushima Site Leaking Radioactive Wastewater


Radioactive water has been found leaking from storage tanks at the site of the Fukushima reactors which melted down in the wake of the 2011 tsunami. Three of the eight reactors at the site melted down after cooling systems failed due to damage caused by the tsunami.

Storage tanks have been built near the crippled reactors to store the great quantities of the best choice low price levitra water being used to cool off the cialis in spain damaged reactor cores. The melted reactors will need to be cooled off for years before further decontamination work can take place.

The leak has been classified as a low-level (Level 1) incident, but still, the radioactivity of the leak has been characterized as "equivalent to the limit for accumulated exposure over five years for nuclear workers."

Considering the Environmental Impact of 3D Printing


Manufacturing with 3D printing is now a fast-growing field, with the technology becoming more accessible and affordable. Some think that it will revolutionize all kinds of manufacturing. But, while it offers some advantages, the process can be energy intensive and wasteful of material. A recent study has a comparison of some 3D printing and levitra prescriptionsgeneric levitra sale conventional milling methods.

There are many different kinds of 3D printing, and this study is only an early examination of a few methods. The environmental impacts between different printers (different printing methods) were not as great as the those between occasionally operated printers and ones in more consistent production (which is more efficient). "In cases like this, job shops legitimately can argue that they provide both economic and environmental advantage to their customers."

Equally importantly, the kind of www.celebratinglife.org object being produced can make a huge difference in the amount material used. An object with a great deal of hollow space will be easier to tramadol fedex overnight delivery produce by 3D printing rather than milling. In some instances, "an inkjet 3D printer (which lays down polymeric ink and UV-cures it layer by layer) wastes 40 to 45 percent of its ink, not even counting support material, and it can't be recycled."

Regardless of method, 3D printing is not going to replace other methods of mass production, any more than laser printing replaced all conventional printing. "3D printing is not going to replace injection-molding for mass-manufactured products (plastic parts made in the millions). It is replacing machining for smaller runs (1 unit, 10 units, maybe 1,000 units)." Each has its advantages, for its appropriate application.

Microbes Thriving on Plastic Ocean Pollution

From the Great Pacific garbage patch to more disperse bits of trash, immense amounts of plastic and other garbage continue to amass in the ocean. However, some of viagra gel online without prescription that plastic pollution is http://grefa.org/viagra-philippines harboring life. Scientists have discovered colonies of microbes thriving on tiny fragments of plastic floating in the open ocean. The team of scientists studying these new ocean habitats--called the "plastisphere"--collected marine plastic debris using fine-scale nets at locations in the North Atlantic Ocean. They discovered at least 1000 kinds of bacterial cells, forming a variety of complex microscopic communities.

Many microbial species on the http://www.breinweb.nl/cialis-rx debris samples remain unidentified, and identifying the microbes present isn't the only task at hand. As Science Daily reports, scientist Linda Amaral-Zettler says, "We're not just interested in who's there. We're interested in their function, how they're functioning in this ecosystem, how they're altering this ecosystem, and what's the ultimate fate of these particles in the ocean ... Are they sinking to the bottom of the ocean? Are they being ingested? If they're being ingested, what impact does that have?"

One debris sample studied mostly contained certain strains of look here viagra soft gel Vibrio bacteria that cause cholera; disease-causing bacteria thriving on plastic instead of something less durable like driftwood may have a better chance of spreading disease across the ocean. However, some of the microbes found on purchase cialis overnight delivery the plastic debris may be capable of degrading hydrocarbons. The team found microscopic pits in the plastic surfaces on samples made of different kinds of resins. Genetic sequencing will identify these microbes, and further research will explore whether some of these microbes can actually digest the plastic garbage they find so appealing.

The plastisphere study was published online in Environmental Science & Technology.

Temperature Extremes In Both Hemispheres

Recently, there have been a couple of extreme climate effects noted. Record high temperatures have made the news on two continents in the northern and southern hemispheres.

In the United States, to the surprise of no one who experienced it, 2012 was the hottest year on record by more than a degree, with hundreds of fda approved viagra sales new temperature records set throughout the year. The average national temperature was a full degree higher than the previous record. A degree of temperature may not seem like much, but when talking about an average over a year, that's a huge spike. "Normally, records are broken by a tenth of a degree or so."

And, in Australia, recent temperatures have gotten so hot that the Bureau of Meteorology has had to add new colors to those it uses on its interactive weather forecasting chart. Until now, the temperature maps have gone up to www.syncom.nl 50 degrees C (122 F), but that hasn't been enough for recent high temperatures. Now, the new scale extends to 54 C (129 F).
