China : largest importer of Brazilian agricultural products

 

Brazilian food products has been welcomed and loved by Chinese consumers for some time now. According to the Brazilian Agriculture and Brazilian Fisheries Department’s latest data, for the first time last year, the EU has been surpassed by China in becoming Brazil’s largest export country of agricultural products. China’s agricultural imports from Brazil totalled US$22.88 Billion, with an increase of US$4.91 Billion from 2012. Why are Brazilian agricultural products popular with the Chinese? The reason lies not only in its diversity, but also in its high quality.
Brazilian agriculture and animal husbandry is very developed and is one of the main producers in the world of; coffee sugar, citrus, corn, chicken, beef, tobacco, soybeans. Exporting to countries such as the US, Japan, China, Belgium, etc.
Brazil is located in the southern hemisphere’s tropical climate zone, an area of vast plains, arable fertile land rich in resources. Brazilian agriculture is constantly developing and moving forward. Brazil foods are extremely outstanding in both quality and quantity.
The Brazilian government has given great importance to its agricultural development. Data shows that agriculture and animal husbandry accounted for 22.5% of Brazil's GDP, exports of agricultural and livestock products accounted for nearly 40% of Brazil's exports. In recent years, Brazil has continued to increase its investments in scientific and technological innovations in agriculture, to improve agricultural production efficiency.

Greatest Invention in Human History Helps You Avoid Certain People

 

 

The era of antisocial networking has begun with the development of apps such as Cloak, which identifies locations of your contacts so you don't have to see them. Larry Greenemeier reports.  

Mar 28, 2014 |By Larry Greenemeier

You’re walking near the park when your iPhone chimes. It tells you that one of your many Foursquare contacts is enjoying a coffee at an outdoor café on the next block. So you turn on your heel and head the other way.
Welcome to the era of antisocial networking. Where you filter pictures of your friends’ kids out of your Facebook feed, replace inane tweets with those you actually care about and keep tabs on people you’d rather avoid.
The
Cloak app, for example, collects location info from Instagram and Foursquare to let you know where your so-called “friends” are—so that you never have to see them. It scans their most recent check-ins, and plots those locations on a map. It can even alert you when the guy you owe twenty bucks to is nearby.
Cloak developers Brian Moore and Chris Baker say they came up with the idea after too many chance encounters with ex-girlfriends. They plan to expand Cloak to interface with other apps, including Facebook. And they insist their feelings won’t be hurt if they suddenly stop bumping into their Cloak-using friends.

Q: Is coconut oil OK to use for people with heart disease? My doctor cautions against its use.

— Deborah S., Lakeland, Fla.

A: Unfortunately, the medical profession continues to propagate this myth. Most medical research finds that there is little link between saturated fats and heart disease. In the case of coconut oil, there is no positive link to heart disease, but there is a strong link to preventing heart disease.

I would caution that you should use only extra-virgin coconut oil, which is high in a healthy oil called MCT (medium chain triglyceride) as well as a number of healthy flavonoids (the extra-virgin part). The strongest link to heart disease and fats comes with the very oils most promoted by the medical profession and dieticians — omega-6 fats, such as corn, safflower, sunflower, peanut, soybean, and canola oils.

These oils rapidly oxidize, and this aggravates the inflammation within blood vessels, which is the primary cause for atherosclerosis. Unfortunately, most doctors know so little about nutrition they just repeat tired old myths such as this.

Q: Are there any natural foods or supplements that would help cope with hepatitis C?

— Rod M., Anaheim, Calif.

A: Yes, there are a number of natural treatments that have shown benefit. At the top of the list are R-alpha-lipoic acid, taurine, indole-3-carbinol, a multivitamin/mineral (such as from Extend Core), vitamin C (buffered), vitamin E (mixed tocopherol with high gamma E), N-acetyl-L-cysteine, astaxanthin, white tea, and beta-1,3/1,6 glucan, which is an immune stimulant that boosts cellular immunity.

Most of the liver damage caused by this virus is what is called bystander damage; that is, free radical damage. Reducing free-radical and lipid-peroxidation damage dramatically lowers the risk of subsequent liver cancer and preserves liver function. It is also important to avoid excitotoxic food additives, such as MSG, hydrolyzed proteins, soy proteins, autolyzed yeast, etc. Resveratrol, grape seed extract, and curcumin reduce liver damage and inhibit viral replication.

Alert: What Is Your Risk for a Heart Attack? Find Out Now

Look, Smartphone: No Hands!

 

Controlling an iPhone or Android phone with just your voice and a noise-cancelling headset is doable, but frustrating.

Why It Matters

As gadgets continue to get smaller, we’ll need new ways to interact with them easily, such as with voice or gestures.

So controlling: There are plenty of things you can do on your smartphone via voice control. Texting isn’t always that easy, though.

I usually enjoy making fun of people who walk around wearing Bluetooth headsets, seemingly talking to themselves. So of course I felt like a hypocrite last week wandering around downtown San Francisco doing exactly that.

I had an excuse, though. The rise of wearable gadgets means touch displays are getting ever smaller, and in some cases they may not be the best way to interact with these new devices. Voice-activated assistants like Siri and Google Now, meanwhile, are becoming increasingly popular. So I wanted to see how easy it would be to control both an iPhone and an Android smartphone with my voice, without having to touch them (spoiler: not very, but voice control does show promise).

For the experiment, I used Jawbone’s new Era Bluetooth headset ($100), which has noise-cancelling technology meant to help it pick up your voice even in loud places, and which can control both Siri and Google Now without your taking your phone out of your pocket (though you’ll still have to press a button on the headset itself). It also supports wideband audio (aka HD voice), which is emerging on some handsets and networks and can make speech recognition easier.

The Era is extremely compact—a bit less than two inches long, about half an inch tall—and weighs just six grams. Like Jawbone’s other products, it has a sleek, high-fashion look: it’s a faceted bar with a power switch hidden next to the earpiece and a single button on its rear end. The matte black one I tested nestled close to my cheek, easily hidden if I wore my hair down (which I did when using it in public, since even though it’s good-looking relative to other Bluetooth headsets, I didn’t want to show it off).

As with other wearable technology, power is a major concern. You wouldn’t be able to get through an entire day of ordering your smartphone around via the Era, as you get just four hours of talk time on a charge. But realistically, you probably wouldn’t be using it nonstop, and buying it with its optional charging case ($130 for the pair) will give you about six more hours of juice if you plug it into the case when not using it.

Jawbone has created an app for iPhones and Android devices that lets you customize some of the Era’s functions. I set it to know that one long press on the button meant I wanted to use either Google Now or Siri, depending on which smartphone it was connected to at the time.

First I tried out the Era with Siri on my own iPhone 5S. In the middle of the day I headed to San Francisco’s Union Square—a bustling shopping district—and started talking to my phone, which was hidden in my back pocket. The Era was able to pick up my voice so Siri could accurately respond to my commands on crowded streets and in busy stores. I had it read my work e-mail aloud and composed a response for it to send; I had it post undoubtedly clever tweets and define words for me while I walked through a busy shopping mall and its surrounding neighborhood.

It was easier to interact with my iPhone this way than by holding down the button on its face to summon Siri, and I was impressed by how much I could get done without even looking at the phone’s screen, which my eyes are normally glued to. Although I felt weird talking to my phone in public, I could imagine using the Era to interact with it and other gadgets at home, especially in the kitchen when my hands might not be free.

Siri still had a hard time understanding some things, especially when I tried to play music by musicians like Ferraby Lionheart and CeeLo Green, or used words with “ee” sounds. In one particularly vexing exchange about an upcoming party, I learned that Siri really doesn’t like the word “theme,” at least not the way I pronounce it. Instead, I got “FEMA,” “Tina,” and “fee” (twice).

Despite some difficulties recognizing artists’ names, the Era was best for simply playing music, as it has excellent sound quality and I could use Siri to skip tracks and pick artists (when I was multitasking, having tunes in one ear was fine). Adjusting sound or switching tracks was kind of a pain, though: to turn sound up or down via the Era, you have to hold down its one button and let the volume cycle all the way down and then all the way up, releasing your finger when it gets to the right level.

All ears: Jawbone’s new Era Bluetooth headset can be used with an iPhone or Android smartphone to control Siri or Google Now.

Then it was on to testing the Era with an Android smartphone. I quickly realized that Google Now’s ability to understand what I was saying was superior to Siri’s, but it still had some problems doing things like creating and sending messages if I didn’t enunciate as clearly as possible.

The Era also had trouble launching Google Now if the phone was asleep. Holding the button would bring me into the phone’s voice dialer; I had to do a short button press to cancel that before another long press brought up the general voice search that let me do things like check my appointments and get directions.

Whether on the iPhone or Android, the Era did a good job of cancelling noise when I was walking or standing still in crowds, but when I was cycling the wind generally drowned out my attempts to tell it to do things like play music or place a phone call. This is important. If your voice is the only way to control a gadget like a smart watch or head-worn computer, you will need the microphone to be robust enough to counteract wind so you can use it for all kinds of outdoor activities.   

Oddly, both handsets had a really hard time understanding when I tried to dial sources and editors who weren’t in my address book, resulting in a lot of frustration. And when I finally got through, while I could hear the person on the other end just fine, several of them complained that I was hard to understand or cutting in and out. In two of those cases, I was alone in my office or at home, so it wasn’t an issue of background noise.

To get the perspective of someone who’s been in the speech-recognition trenches long enough to know how far the technology has come (and how far it still has to go), I called Jim Glass, who heads MIT’s Spoken Language Systems Group and studies automatic speech recognition and spoken-language understanding. (I actually called him first using the Era and the Android handset, but he said he couldn’t hear me well, so I hung up and called him back from my land line.)

Glass does think that as gadgets get tinier, voice will become an increasingly natural way to interact with them. Still, he says that while speech recognition will improve, there will continue to be people for whom it won’t work well, such as nonnative speakers of the language that’s being scrutinized. For this and other reasons, he thinks it’s best if wearable gadgets offer multiple ways to interact. People might not mind chattering alone in the car, but not everyone is comfortable doing so on the bus.

“I think giving people choice is always the best option when you can,” he says.

I agree, in part because I couldn’t shake the feeling that I looked completely bizarre muttering to myself while using the Era in public. I suspect erasing that feeling will prove to be even more difficult than improving the speech recognition.

Microsoft Builds a Digital “Monkey” to Hunt Fraudulent Ads

 

A new tool roots out ads that are too easy for users to accidentally click.

By David Talbot on March 28, 2014

Why It Matters

Almost half of all clicks on ads in apps are inadvertent.

Ads on mobile apps generate more than $8 billion in annual revenue for app developers. With so much money at stake, various ways to game the system have arisen. One fraudulent method is to write malicious code to generate false clicks (see “A Web Scam That Makes $500,000 a Month”). A more insidious approach is to simply make it easy for users to hit ads through “placement fraud.” Developers can make ads too small to stand out, too close to a game button, or even invisible.

Now researchers at Microsoft and the University of Southern California have come up with what they say is the first publicly disclosed technology for detecting and countering placement fraud at a large scale. They’ve built what they call a digital “monkey” to hop between millions of app screens to see whether designs violate an app store’s terms of use.

When the technology was deployed on 50,000 Windows Phone apps, it uncovered more than 1,000 that had ad placements that violated the terms of use; of 1,200 Windows 8 tablet apps, it found more than 50 with problems. The work, done in April 2013, is the subject of a paper being aired next week at the Usenix conference in Seattle.

With millions of apps for sale, it’s infeasible for humans to do a visual inspection. That’s one reason why most research attention has been focused on the problem of click fraud, in which automated programs called bots click ads.

Microsoft’s new tool systematically reviews apps in an app store, launches an app in an emulator, and then interacts with that app and attempts to go through as much of it as it can. If the monkey encounters a button, it clicks on it. If it encounters a text box, it tries to continue by determining what is being sought and entering something, such as a zip code. “The goal of the monkey is to go to as many pages in the app as possible,” says Suman Nath, a senior researcher at Microsoft.

One of the sneaky gambits Microsoft’s monkey rooted out was inside an app for playing mah-jongg, the Chinese tile game. A vertical advertising bar on the right side of the screen was filled with tiles that looked like the tiles used in the game itself. “The user will believe this is an ad-free app,” Liu says.

Other app authors shrunk ads to fit a given game layout, unaware of or flouting the fact that the app store’s terms of use disallow ads that are smaller than a certain size.

Xuxian Jiang, a computer scientist at North Carolina State University and an expert in mobile security, says the work was novel. Even though it can’t detect whether the bad ad placement was intentional, “it is a good start,” he says.

Skyline of Leipzig, Germany


The skyline of Leipzig, Germany

The skyline of Leipzig, Germany. Cities are growing around the world, and understanding how urbanization and urban gardening impact biodiversity and ecosystem services is increasingly important.
There are more plant species in cities in both the U.S. and Europe than in rural areas. Plant species in urban areas are more closely related to each other and often share similar functions. Consequently, urban ecosystems should be more sensitive towards environmental impacts than rural ecosystems. This is concluded by German and U.S. scientists based on a field study in Minneapolis (Minnesota) led by Jeannine Cavender-Bares, associate professor at the University of Minnesota. The new study confirms results obtained by Dr. Sonja Knapp and colleagues of Helmholtz Centre for Environmental Research (UFZ) in a study on the German flora in 2008. The new results have been published as a preprint in Ecology and have been highlighted in the renowned science magazine Nature.

Manmade "Wall of Wind" creates hurricane force winds to test construction -- Science Nation

Manmade "Wall of Wind" creates hurricane force winds to test construction A Category 5 hurricane is a monster of a storm that most people would want to avoid. But, civil engineer Arindam Chowdhury actually recreates those monster hurricane force winds in hopes of helping us better prepare for the real thing. Chowdhury and his team at Florida International University (FIU) and the International Hurricane Research Center designed a 15-foot-tall "Wall of Wind," aptly nicknamed WOW. The wall is made up of 12 giant fans. They can create the intensity of a Category 5 hurricane with 157 mile-an-hour winds. The team's goal is to see if low-rise structures and building materials can withstand the same wind forces they would face in a full-blown hurricane. Credit: National Science Foundation
