The vascular precursor cells of the procambium differentiate to form continuous vascular strands, from which xylem and phloem cells are generated in the proper spatiotemporal pattern. Procambium formation and xylem differentiation are directed by auxin. In angiosperms, thermospermine, a structural isomer of spermine, suppresses xylem differentiation by limiting auxin signalling. However, the process of auxin-inducible xylem differentiation has not been fully elucidated and remains difficult to manipulate. Here, we found that an antagonist of spermidine can act as an inhibitor of thermospermine biosynthesis and results in excessive...

These 12 Twitter posts show the insane queues for masks in Singapore, Shanghai and Hong Kong, which are all sold out, Business Insider

As the number of people falling victim to the Wuhan virus rises, stocks of surgical face masks are plunging across Asia, as anxious citizens form snaking queues at supermarkets and pharmacies to stock up. Over the past week, netizens claim masks have sold at out most stores in cities like Singapore, Shanghai, and Hong Kong, with many uploading photos and videos of the insane queues that have formed in stores still offering precious stocks of the item. Long line of people buying masks instead of the state providing them. Want to guess how many infected are in that line without masks? Slow it down and see

Arlo Video Doorbell review: Nest and Ring should be worried about this nicely equipped, solid value

How are you going to call yourself a smart-home company, one with a huge focus on video, and not have a video doorbell? That’s a question Arlo had no doubt been asking itself for some time, and while it launched its Audio Doorbell with matching wireless Chime back in 2018, that one was largely meant to be used with the company’s existing video cameras. It took another year for the follow-up effort to arrive, but in late 2019 we finally got a proper Arlo Video Doorbell. How will this new entry compare against Arlo’s existing lineup of impressive cameras? What about video doorbells from other smart-home manufacturers? And is this going to be an easy upgrade for you, or should you think about calling an electrician? Let’s get right into what the Arlo Video Doorbell has to offer: The design of the Arlo Video Doorbell should be pretty familiar to anyone with even a passing interest in smart doorbells — if you’ve seen a Nest Hello, the Video Doorbell is going to look like its spitting image. That means a wide-angle camera up top, and a big illuminated button below — just like with Arlo’s Audio Doorbell, that button lights up when the unit detects motion to clu...

People who face homelessness in the area no longer have to be unsure about what to

People who face homelessness in the area no longer have to be unsure about what to expect when they walk into one of HELP’s “A Night’s Welcome” shelters. Members of Next Level Church have rallied to buy new blankets at the Hampton organization, and while it may not seem like much, Matthew Stern, executive director for HELP, said “it’s more dignifying when everyone can expect the same quality and experience when they come into a shelter.” “We just had a hodgepodge of blankets that felt like ‘homeless blankets,’” he said. “They were miss-matched, some were heavy, and not every guest would get the same size.” The church raised enough to buy 250 twin-sized hotel quality blankets, or enough for 125 people while the others could be washed in the laundry, Stern said. Scott Rutter, executive pastor at the Yorktown based church, said giving to A Night’s Welcome was part of the congregation’s monthly “Make a Difference” initiative to partner with organizations in the community who they feel are making an impact. “God’s love has transformed us for the better and so we want to take that love out into our community and transform it for the better,” he said. “Our strategy has always been to f...

Global Industrial Valve Market is Expected to Reach USD 93.79 Billion by 2026 : Fior Markets

Industrial Valve Market by Valve Type (Ball, Butterfly, Gate, Globe, Check, Plug), Regions, Global Industry Analysis, Market Size, Share, Growth, Trends, and Forecast 2019 to 2026 New Jersey, NJ, Jan. 22, 2020 (GLOBE NEWSWIRE) — As per the report published by Fior Markets, the global industrial valves market is expected to grow from USD 70.17 billion in 2018 to USD 93.79 billion by 2026, at a CAGR of 3.66% during the forecast period 2019-2026. Industrial valves are built to handle high pressure of fluid or gas, and to last through years of use in harsh environments. Most utilities, from water to oil and gas, have high requirement of heavy duty, industrial-strength valves. Industrial valves are of various types such as ball valves, butterfly valves, check valves, pressure valves, gate valves, globe valves, and diaphragm valves etc. The flow of liquids or gases can be controlled using these valves. This can be done through pipes and other passageways by opening, closing, and partially obstructing the passageway or pipe. The growing demand for flow control equipment is expected to fuel market growth over the forecast period. In addition to this, smart valves with intelligent ...

Judging by the number of times I’m asked about it, the The One For All SV

Judging by the number of times I’m asked about it, the The One For All SV 1760 solves one of the nation’s most pressing AV issues, allowining you to ‘beam’ audio and video wirelessly from an HDMI source in your main living room to a distant projector or a TV screen in another room. It’s a simple concept and there are some drawbacks, but for many households it’s a timely solution to an annoying problem. Despite having the Wireless HDMI Sender installed for a couple of weeks at the time of writing, I still find myself flip-flopping over whether I admire the business-like design or whether it’s actually just a bit dull. They look like tiny wireless routers with perforated holes spcing up an otherwise grey-and-black design.Thanks to their small size it’s pretty easy to hide them from view if you decide they’re not the ideal ornaments for your AV kit shelf or mantelpiece. You can lie them both flat if you wish, though they cut a more elegant profile if you slot them onto the little hexagonal feet One For All provides in the box. The basic idea behind the One For All Wireless HDMI Sender is simple: to send full HD, even 3D video – with accompanying audio – wirelessly from an AV source...

Why handwritten letters are becoming more precious in an increasingly digital world

For most of my three years working at a luxury writing shop in Perth, the most expensive pen was the Mont Blanc Marlene Dietrich, a special-edition fountain pen in commemoration of the actress. It had an 18-carat solid gold nib (of course), inlaid mother-of-pearl on the top of the cap and a diamond adorning the clip, which was shaped like the ties of which its namesake was so fond. That, in turn, was not the most expensive pen the store had ever had — that honour went, I was told, to a Caran d’Ache fountain pen that was literally encrusted with hundreds of diamonds. It was worth $1.7 million and travelled pen stores worldwide. Wherever it went, it apparently came with its own security guard. It makes my most expensive sale look like utter peanuts, but thankfully it doesn’t cost thousands to partake in the joy of writing. From working at the pen shop I learned that no matter how bad one’s handwriting is, or how rarely they put pen to paper, almost everyone harbours some kind of love for stationery. Industry experts say that no matter how flash the newest iPad might be, pen and paper are here to stay. Fountain pens rose to prominence in the first half of the 20t...

TribLIVE’s Daily and Weekly email newsletters deliver the news you want and information you need, right

TribLIVE’s Daily and Weekly email newsletters deliver the news you want and information you need, right to your inbox. Whether it’s a preference for online browsing, time constraints or anticipating a package’s arrival, many people embrace a “personally curated,” often subscription-based shopping service. “It’s like getting a little present in the mail every month,” Linda Brasile says of her regular Stitch Fix deliveries. Customers submit preference profiles, let stylists choose their “fix” — five pieces of apparel, accessories or footwear — and pay a $20 styling fee per shipment. They can keep what they like, with the $20 fee credited toward a purchase, and return the rest at no cost, according to its website. Brasile and her sister, Barb Twaddle, both enjoy shopping. Each has tried a few of the numerous online subscription services, as have several family members. Brasile says she can choose the frequency of shipments. She likes the styling cards that suggest ways of wearing the items in each package. She gets a 25% discount if she elects to keep all five items in a shipment. “I like things I can dress up or down,” says Brasile, finance administrator at the Arnold Palme...
