Climate change and human activities, including heat emission, nitrogen (N) emission and water management, are altering the hydrothermal condition and N transport in the soil and river systems, thereby affecting the global nitrogen cycle and water environment.
“We need to assess the impacts of these human activities on global river temperature and riverine N transport,” said Prof. Xie Zhenghui from the Institute of Atmospheric Physics of the Chinese Academy of Sciences. “Quantitative assessment can not only improve our understanding of the material and energy cycle that occur in response to anthropogenic disturbances, but also contribute to protecting river ecosystems.”
Xie and his collaborators from the Chinese Academy of Sciences incorporated the schemes of riverine dissolved inorganic nitrogen (DIN) transport, river water temperature, and human activity into a land surface model, and thus developed a land surface model CAS-LSM. They applied the model to explore the impacts
Driver fatigue brought on by the monotonous drone of road roar and wind noise could soon be a thing of the past, as Jaguar Land Rover reveals new noise-cancelling technology.
Similar to how headphones with ANC (active noise cancelling) work, the new system uses sensors on each wheel to monitor vibrations. These are then used to produce a sound wave through the car’s audio system that cancels out the unwanted noise, particularly low-frequency sounds up to 300Hz.
The system debuts on the new Jaguar F-Pace, new Jaguar XE, and Range Rover Velar, but is likely to soon roll-out across the rest of the JLR range.
JLR explains how the system “calculates the opposite phase sound wave needed to remove the noise heard by the
(Reuters) – Tesla’s upcoming quarterly report could put another $3 billion in Chief Executive Elon Musk’s pocket.
The electric car maker on Tuesday saw the six-month average of its stock market value hit $250 billion, a milestone toward triggering the fourth of 12 tranches of options to buy Tesla stock at a discount, granted to the billionaire in his 2018 pay package.
Musk’s compensation is exclusively made up of a series of potential stock options rewards based on market capitalization and operational goals. To secure Musk’s fourth tranche, Tesla still must hit a goal related to revenue or profitability, and that could happen in the company’s third-quarter report, the date of
2020 Land Rover Defender 110 first drive review: Off-rad chops meets modern tech
“The 2020 Land Rover Defender combines old-school ruggedness with modern refinement.”
Impressive off-road capability
Drives like a car, not an SUV
Modern Land Rover is defined by SUVs that combine luxury with off-road capability, vehicles that, despite their mud-plugging abilities, are typically compared to the likes of Mercedes-Benz. It wasn’t always this way.
When Land Rover launched in 1948, it made simple, rugged vehicles aimed more at farmers, explorers, and soldiers than wealthy suburbanites. Those early Land Rovers were Britain’s answer to Jeep, not Mercedes. As Land Rover drifted further into luxury, the Defender became the last reminder of the brand’s origins. Until it went out of production in 2016, that is (United States sales ceased in 1997).
Fans loved the original Defender because it existed in a time
Born in Tanzania in 2014, Magawa has since age 2 enjoyed a highly successful career detecting land mines in Cambodia. So far, he’s found 39 land mines and 28 items of unexploded ordnance, according to Apopo, a global nonprofit started in Belgium that breeds and trains rats for humanitarian work such as sniffing out land mines and tuberculosis.
Magawa’s impressive record makes him Apopo’s most successful working rat, or “HeroRat,” to date. It also makes him the first rat in UK animal charity PDSA’s 77-year history of honoring critters to win a coveted PDSA Gold Medal. Other animals to receive the award have included dogs, horses, a pigeon

Not long ago, getting a job at a big tech company meant you had to live in one of the tech hubs such as Silicon Valley, Seattle, New York, or Boston. Even if you planned to work from home most or all of the time, you would likely need to be located near to the company’s offices, or at least in the
