How wind formed largest dust deposit on Earth

Washington: China’s Loess Plateau — the largest dust deposit in Earth — was formed by wind alternately depositing dust or removing dust over the last 2.6 million years, according to geoscientists from University of Arizona.

The study is the first to explain how the steep-fronted plateau formed.

About the size of the state of Arizona, the Loess Plateau is the largest accumulation of dust on Earth.

Deposits of wind-blown dust known as “loess” generally create good agricultural soil and are found in many parts of the world, including the US Midwest.

“Wind blew dust from what is now the Mu Us Desert into the huge pile of consolidated dust known as the Loess Plateau,” said lead author Paul Kapp, professor of geosciences.

Just as a leaf blower clears an area by piling leaves up along the edge, the wind did the same thing with the dust that was once in the Mu Us Desert.

“If the blower keeps blowing the leaves, they move backward and the pile of leaves gets bigger,” Kapp said. “There is a boundary between the area of leaves and no leaves.”

The team also found that, just as a leaf blower moves a pile of leaves away from itself, wind scours the face of the plateau so forcefully that the plateau is slowly moving downwind.

“You have a dust-fall event and then you have a wind event that blows some of the dust away,” Kapp said. “The plateau is not static. It’s moving in a windward direction.”

Linear ridges on the top of the Loess Plateau are also sculpted by the wind, the researchers found.

“The significance of wind erosion shaping the landscape is generally unappreciated. It is more important than previously thought,” the authors noted.

The paper is forthcoming in the journal Geology.

Casino Days Reveal Internal Data on Most Popular Smartphones

International online casino Casino Days has published a report sharing their internal data on what types and brands of devices are used to play on the platform by users from the South Asian region.

Such aggregate data analyses allow the operator to optimise their website for the brands and models of devices people are actually using.

The insights gained through the research also help Casino Days tailor their services based on the better understanding of their clients and their needs.

Desktops and Tablets Lose the Battle vs Mobile

The primary data samples analysed by Casino Days reveal that mobile connections dominate the market in South Asia and are responsible for a whopping 96.6% of gaming sessions, while computers and tablets have negligible shares of 2.9% and 0.5% respectively.

The authors of the study point out that historically, playing online casino was exclusively done on computers, and attribute thе major shift to mobile that has unfolded over time to the wide spread of cheaper smartphones and mobile data plans in South Asia.

“Some of the reasons behind this massive difference in device type are affordability, technical advantages, as well as cheaper and more obtainable internet plans for mobiles than those for computers,” the researchers comment.

Xiaomi and Vivo Outperform Samsung, Apple Way Down in Rankings

Chinese brands Xiaomi and Vivo were used by 21.9% and 20.79% of Casino Days players from South Asia respectively, and together with the positioned in third place with a 18.1% share South Korean brand Samsung dominate the market among real money gamers in the region.

Cupertino, California-based Apple is way down in seventh with a user share of just 2.29%, overshadowed by Chinese brands Realme (11.43%), OPPO (11.23%), and OnePlus (4.07%).

Huawei is at the very bottom of the chart with a tiny share just below the single percent mark, trailing behind mobile devices by Motorola, Google, and Infinix.

The data on actual phone usage provided by Casino Days, even though limited to the gaming parts of the population of South Asia, paints a different picture from global statistics on smartphone shipments by vendors.

Apple and Samsung have been sharing the worldwide lead for over a decade, while current regional leader Xiaomi secured their third position globally just a couple of years ago.

Striking Android Dominance among South Asian Real Money Gaming Communities

The shifted market share patterns of the world’s top smartphone brands in South Asia observed by the Casino Days research paper reveal a striking dominance of Android devices at the expense of iOS-powered phones.

On the global level, Android enjoys a comfortable lead with a sizable 68.79% share which grows to nearly 79% when we look at the whole continent of Asia. The data on South Asian real money gaming communities suggests that Android’s dominance grows even higher and is north of the 90% mark.

Among the major factors behind these figures, the authors of the study point to the relative affordability of and greater availability of Android devices in the region, especially when manufactured locally in countries like India and Vietnam.

“And, with influencers and tech reviews putting emphasis on Android devices, the choice of mobile phone brand and OS becomes easy; Android has a much wider range of products and caters to the Asian online casino market in ways that Apple can’t due to technical limitations,” the researchers add.

The far better integration achieved by Google Pay compared to its counterpart Apple Pay has also played a crucial role in shaping the existing smartphone market trends.
