Depth-related changes in benthic diatom assemblages of a maritime Antarctic lake

first_imgThe epiphytic diatoms of filamentous matforming algae in Sombre Lake, Signy Island, South Orkneys, Antarctica were examined in a field study from January to March 1987. Results reveal 1) a shallow shelf assemblage, dominated by Fragilaria spp, with high percentages of empty frustules, and low numbers of viable cells and, 2) a mid-depth zone containing the most luxuriant epiphytic growth dominated by Achnanthes minutisima Kütz., Synedra rumpens var. familiaris (Kütz) Hust., and Cymbella minuta Hilse ex Rabenh., and 3) a deep water assemblage with low numbers of actively growing cells, dominated by Stauroneis anceps var. hyalina M. Perag. et Brun. in Hérib. The comparison of methods and their impact on ecological interpretation is discussed together with a consideration of the principal factors potentially influencing community structure.last_img read more

Who plays on ‘Sunday Night Football’ tonight? Time, TV channel, schedule for Week 11

first_imgFor those who can’t watch Bears vs. Rams on TV and wish to find the game on the radio, the Chicago call can be heard on Sirius channel 81 and XM channel 225, and the Los Angeles call can be heard on Sirius channel 83 and XM channel 226.MORE: Watch every NFL game and RedZone on DAZN (Canada only)Sunday Night Football TV schedule 2019All “Sunday Night Football” games start at 8:20 p.m. ET.Week 1Sept. 5 (Thur.)Packers at Bears Part of the struggles for both Chicago and LA has been the well-documented and shaky play of their quarterbacks. Yet, the Bears and Rams have reasons to believe Mitchell Trubisky and Jared Goff will perform to par Sunday night.MORE: Full betting preview for Bears vs. RamsTrubisky passed for 3 touchdowns and no interceptions in last week’s win over the Lions, with his 131 passer rating marking the third time in his career he has hit 130 or better. The Bears QB also has a 2-0 record in his only two career road starts against NFC West teams.As for Goff, it’s all about playing at home. The Rams QB has 3,279 passing yards, 23 TDs, 4 INTs and a 106.6 passer rating over his last 10 starts in LA. And as good as Trubisky has been on the road against the NFC West, Goff has been even better at home against the NFC North — as evidenced by his 8 TDs, 0 INTs, 380 yards per game and 143 rating in those two such games.Below is all the info you need to watch Bears vs. Rams on Sunday night, including the TV channels and kickoff time.Who plays on Sunday Night Football tonight?Matchup: Chicago Bears at Los Angeles RamsKickoff time: 8:20 p.m. ETIn our Week 11 NFL picks against the spread and straight-up predictions, Sporting News is split on Sunday night’s game. Below are the explanations for each pick.Pick against the spread: Mitchell Trubisky used the Lions to break out of a massive slump while Jared Goff went deeper into his struggles against the Steelers. The Bears can run the ball on the Rams to make Trubisky comfortable while the Rams face more tough sledding for Todd Gurley and more pressure on Goff. Chicago should have a good fan presence, as well, Sunday night in Los Angeles. Pick: Bears win 23-20.Straight-up prediction: Before the season, anybody could have reasonably stated this Week 11 matchup was a preview of a playoff game in the NFC. It technically still could be, but neither the Bears nor the Rams inspire much optimism. The Bears finally showed some signs of offensive life in their win over the Lions last week, but the Rams, despite some struggles of their own, still have the more trustworthy attack. LA’s defense will get back on track, and coach Sean McVay will scheme his way to enough points for a win.

It aims to make it easier than ever before to learn to play the game.It was trialled in Warwickshire last year and prompted enthusiastic feedback, including this comment from a novice who went on to become a golfer:“The informality and age range of all participants created a very relaxed introduction to golf and there was absolutely no embarrassment in being a total novice.“From this introduction to golf, and with others who started with me, I went on to take part in group coaching during the winter months and now play with some confidence on an 18 hole course with golfing partners that I met from participating in golf in the park. Looking back the total activity became a relaxed social event.”Another beginner remarked: “The opportunity for me and my family to all go and experience how golf should be played by a PGA professional was amazing. We really enjoyed the different activities held each week and the encouragement and one to one time that was still provided to us all to improve. A brilliant experience.”Jason’s coaching covers an introduction to the game, including grip, posture and swing. Anyone interested should just turn up in comfortable clothing and flat shoes to learn the basics, some information about the rules and a little ‘golf-speak.’He’ll also provide a quick refreshers for returners who want to get back on the course. Jason is pictured above, giving a lesson.Anyone interested in further tuition can visit our Get Into Golf site to find great value coaching near them.

Precision agriculture highlighted with Ohio State logo

first_imgShare Facebook Twitter Google + LinkedIn Pinterest From the ground, it looks like just another Midwestern cornfield. Nothing special.Fly a few hundred feet above the cornfield, and a clear image comes into view: a Block O with the words “Ohio State” angled through the middle of it.Buckeye pride? Partly. But the logo also illustrates the power of “smart planting.”As the planter was driven across the field, its computer system knew the rate and variety of seed to sow in each area, having noted the differences in soil type, terrain, drainage and organic content within the same field.Over the past few months, the Block O, Ohio State University’s primary athletic identity, slowly emerged in the cornfield where two different corn hybrids were planted, one with a slower growing rate. So green corn plants form the background, and the drier brown plants create the “O” and “Ohio State.”The logo stands in a field at the Molly Caren Agricultural Center in London, Ohio, home to the Farm Science Review.For last year’s Review, Brutus Buckeye grew up in a field as a result of the same precision planting technology, and before that, a plain Block O — without the words “Ohio State” —emerged. Each image proved challenging for different reasons.“Brutus Buckeye had a lot of curves, and equally difficult this year was creating all the lines and small details for the script letters that spell ‘Ohio State,’ ” said Andrew Klopfenstein, senior research associate engineer with the college, who helps plan the project. “We’ve gotten better at it each year.”While farmers may not want to brand their fields with Ohio State logos, they could see the value in having a planter that can easily sow multiple hybrids of corn or soybeans in the same field and at different rates. A section of a field with rocky terrain may get fewer seeds sown to compensate for the expected lower rate of success for each seed. Alternatively, the base of a hilly section that’s rich in organic matter may get more seeds because more of them are expected to grow in that area.“This allows you to get the most out of the soil and the seeds that you possibly can,” Klopfenstein said. “You give the crop the best chance of producing the largest yield for its growing conditions.”With a standard planter, a grower can’t easily plant one variety of seed, then switch to another.However, there are significant costs associated with the newer technology. Purchased new, a traditional 16-row planter costs about $160,000, and the multi-hybrid and other planter technologies add another $50,000 to the price tag, Klopfenstein said.Using a multi-hybrid planter, research has shown, can lead to a 4- to 5-bushel increase in corn yield per acre, he pointed out. That’s because with a multi-hybrid planter, the right corn hybrid and seeding rate are matched to the soil’s potential to produce grain. The smart planter “knows” about the various soil types and terrain of any field because the data was uploaded to the planter before it sowed the first seed in that field.“If you do the same thing you’ve always done,” Klopfenstein said, “you’re never going to increase the potential of your soil.”The brainpower in the machinery that planted the Ohio State emblem is a series of electronic control units in the planter and in the tractor pulling the planter — technology made by Illinois-based Precision Planting. The smart planting demonstration is part of ongoing research into precision agriculture in the Department of Food, Agricultural and Biological Engineering at Ohio State.

How IoT could benefit from Bluetooth’s new mesh specs

first_imgTags:#Bluetooth#eero#featured#Google#Internet of Things#IoT#mesh network#Samsung#top#Zigbee Follow the Puck When the Bluetooth Special Interest Group (SIG) released the Bluetooth mesh specification in mid-July, the launch heralded something much greater than just a new wireless spec. The move formalized the latest major development in mesh technology that will increase its adoption in Internet of Things (IoT) applications. The technology’s reach in both home and commercial installations of connected devices is expanding by the day, led by a handful of mesh networking standards, or protocols. The Zigbee Alliance first released its low-power mesh networking stack in 2004, which you’ll now find used in smart home solutions including connected lighting offerings from the likes of Philips and OSRAM as well as in smart metering applications widely deployed in the U.S. and Great Britain. A second protocol, Thread, received a big boost for its association with Nest and Google as founding members when launched in 2015. More products on the marketThread-enabled products are just hitting the market thanks to its ability to offer reliable low-power IP mesh connectivity. The efforts of companies like eero, who are putting Thread infrastructure in place integrated with its mesh-based Wi-Fi network, are encouraging other vendors to develop Thread mesh applications. With offerings from Google, Samsung, Netgear, Linksys and Luma, Wi-Fi mesh is becoming more common in the home, further growing the popularity of mesh usage.With the IoT already teeming with mesh networking options, what’s the need for yet another from Bluetooth? It might seem that their addition to the space could confuse a market unsure of which type of mesh should be used for each new IoT development. Each low-power mesh technology has its strengths and best use cases, so we won’t see one dominant mesh standard. See also: IoT and Bluetooth — more tools for developers makes it popularBluetooth does, however, connect 8.2 billion devices today and is projected to be used in 60 percent of wireless devices by 2021 (according to ABI Research). Bluetooth comes in many flavors as well, from classic “one-to-one” communications for continuous voice/audio streaming or device-to-device data transfers to beacon-style “one-to-many” broadcasting. Bluetooth mesh is their newest flavor: adding “many-to-many” communications for large-scale networking applications like asset tracking, home and building automation, lighting, beaconing and smart metering. Zigbee and Thread networks relay messages through a routing technique where a message hops from node to node to reach its final destination. Bluetooth mesh, however, uses a “managed flooding” technique in which every device in the network shouts its message to every other node. Though flooding may be easier and more flexible to deploy for simpler applications, it can also add an overhead of higher latency and power consumption for some larger-scale networks.Why the convergence on mesh?While it’s geeky fun to debate the technical merits of Zigbee/Thread routing versus Bluetooth mesh flooding, developers really just want to understand the answer to one question: “Why are so many wireless standards converging on mesh?” Let’s consider the benefits that mesh brings to the IoT:Extended Range – In a star network topology, all devices have to be in radio range of the central device. We experience this with our cell phones and Wi-Fi: our call may be dropped or our Wi-Fi connection lost when we move out of range. With mesh, having other devices route messages means they can communicate even when they are not in range of each other. Self-Healing Networks – Many early home wireless technologies supported multi-hop performance, but the network configuration was set by hand when the network was installed. Radio conditions and the environment change over time and mesh provides autonomous self-healing by allowing multiple paths between a source and destination.Enhanced Network Reliability – A well-designed and well-implemented mesh network provides exceptional reliability because it can better route around failures or intermittent connections.Scalability – As networks grow to hundreds of devices, having a single, central connection point can create a bottleneck. Building larger, more scalable networks using mesh can enable you to spread the radio load across the network. Improved Energy Efficiency and Battery Life – For devices that are transmitting frequently, transmit power becomes an important factor in battery life calculations. A mesh enables these devices to use lower transmit power with powered routers reliably handling the communications.Despite all this, a mesh will not automatically solve all the IoT’s networking needs. It remains to be seen how well Bluetooth mesh will perform in real-world, large-scale networks. We need to see more field implementations of Bluetooth mesh to evaluate its interoperability, reliability, scalability and performance. Interoperability in particular will become what really matters in a mesh. To date, Bluetooth-enabled products have generally been point-to-point solutions with one vendor controlling the application on both ends. In real-world mesh applications, however, we will see multiple products by different manufacturers that will need to interoperate with seamless message routing and security. Just as Zigbee and Thread have evolved to address interoperability and application layer challenges, Bluetooth mesh will now evolve to meet the needs of a growing and evolving IoT ecosystem, giving developers and end users a new set of solutions designed for larger-scale networks.The author is VP of Software at Silicon Labs, an Austin-based semiconductor innovator whose wireless chips are used by many leading manufacturers of smart home and industrial IoT devices.

Northeastern New Brunswick monastery closes 100yearold dairy operation

first_imgROGERSVILLE, N.B. – A 100-year tradition will come to an end at a New Brunswick monastery Thursday when 80 head of cattle will be taken to neighbouring Nova Scotia for auction.The Cistercian-Trappist Monastery in Rogersville, N.B., has decided to end its dairy operation because of financial problems.Brother Stephan Hewitt, who has been in charge of the herd for 35 years, told Global News that “we don’t make a big profit with the dairy.”Hewitt, who is one of eight monks remaining at the monastery, says it will continue its poultry raising operation, which he says is much more lucrative.Six of their 14 employees will lose their jobs because of the change.The monks plan to look at future ventures such as beer brewing or cheesemaking.The monastery has already auctioned off 82 cattle and the remaining 80 will be sold in Truro, N.S., on Thursday.Hewitt said he plans to accompany the cattle to the auction.“I want to see the girls off one last time,” he said. “Give them a last hug.”(Global News)last_img read more
