NBA free agency rumors: Robin Lopez unlikely to receive buyout from Bulls

first_imgRobin Lopez appears like he’ll be remaining with the Bulls.The 30-year-old center is unlikely to receive a buyout from Chicago, according to a report from the Daily Herald. Players must be waived by Friday in order to maintain playoff eligibility if they sign with another team. “I haven’t even been thinking about it,” Lopez said. “We’ve been having a lot of fun out on the court right now and I’m relishing it.”Bulls coach Jim Boylen praised Lopez’s leadership Tuesday. Related News NBA trade rumors: Celtics told Pelicans ‘everyone can be available’ in potential Anthony Davis deal “It’s invaluable to have a guy who honors his role as an example to the team, a guy who speaks up when a situation needs to be addressed,” Boylen said, via the Chicago Tribune. “What I want is guys who take ownership of our play and mistakes and coach each other and help each other and hold each other accountable. RoLo has done that.”center_img LeBron James ‘killed’ Lakers’ chemistry, league executive says Lopez is averaging 7.9 points and 3.2 rebounds for the Bulls this season.

Residents of Letterkenny estate to hold public protest in Lifford over water outages

first_imgA public protest against ongoing water issues will be held on behalf of residents of Gort Na Gréine, Letterkenny in Lifford on Monday. A spokesperson for the group said that residents of the private estate had suffered severe problems with water access for well over ten years.Local community activist, Finn O Donnell said it was time water outages in the area were resolved once and for all. He said: “It’s disgusting plain and simple. We have families going without a basic human right for over a decade and still there is nothing being done.“The residents are fed up with it and rightly so. I urge everyone who can make it, to come out to Lifford and attend this protest.”The protest will take place on April 15 outside the Donegal County Council Office in Lifford when the final meeting of councillors before the next election is due to take place on May 24.A statment released by the Gort Na Greine Residents Association on Saturday said that the residents had been ‘let down’ by the council for over a decade.”We as residents have been having issues with water in our estate for 10 years,” the statement read. “Time after time we have been let down by the council.“This is a privately built estate with a mixture of privately owned homes, some council-owned houses.“All we want is our basic human right to water. We won’t stop now until we receive this.“We will start with a protest at Monday’s meeting in Lifford and if there is no positive outcome, then we will escalate this to further protests.”Residents of Letterkenny estate to hold public protest in Lifford over water outages was last modified: April 13th, 2019 by Shaun KeenanShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:gort na greineletterkennylast_img read more

This Plant Beats the Venus Flytrap for Speed

first_imgThe waterwheel plant, an aquatic species with a snap-trap faster than the Venus flytrap, is different enough to challenge evolutionary speculations.Most people have heard of or seen the Venus flytrap, one of nature’s most remarkable plants. In a split second, its leaves snap shut around any insect unlucky enough to touch its trigger hairs twice. But have you heard of the Waterwheel plant? Look at its picture in Science Daily reproduced from a press release at the University of Freiburg. Smaller than the Venus flytrap, with traps only 3mm in length, it boasts a much higher snapping action—ten times faster than the Venus flytrap. It was named the Waterwheel because its spokes stick out from the center with a trap on each end. From a water flea’s perspective, it should be called the Ferris Wheel from Hell.An article on the BBC News shows how the waterwheels are arranged along a stem, and says that the plants, though rare, are native to Europe, Africa, Asia and Australia. Being the only other known plant with snap traps, is it related to the Venus flytrap by evolution?Credit: Plant Biomechanics Group.The Venus flytrap (Dionaea muscipula) and the far less known aquatic waterwheel are the only carnivorous plants with snap traps. While intensive research on the Venus flytrap has been going on for a long time, the ten times faster underwater snap traps of the waterwheel have so far been little studied. The team led by the Freiburg biologists has now deciphered the underlying movement principle using experiments and computer simulations. The researchers found that the waterwheel snaps shut its trap, which is only three millimetres in size, by actively changing the internal pressure in the cells of the leaf, which leads to the midrib bending, and also by releasing internal prestress, which apparently results in an acceleration effect. The Venus flytrap, on the other hand, employs a hydraulic mechanism to change the curvature of its leaf halves which results in rapid trap closure. Although both plants share many similarities, the mechanics of the traps differ considerably. This finding may not only help understanding the development of snap traps from an evolutionary perspective, but also the adaptation to different habitats – in a terrestrial habitat with the Venus flytrap, under water with the waterwheel.The Waterwheel plant was the subject of two scientific papers this month. The first one, by Westermeier et al. in the Proceedings B of the Royal Society, reports on “How the carnivorous waterwheel plant (Aldrovanda vesiculosa) snaps.” The authors claim that their study of the mechanical trap of the Waterwheel plant “contributes to the question of how snap-traps may have evolved” but, since the paper is behind a paywall, we cannot analyze their arguments here. It appears from the press release, though, that there are significant differences between the two snap-trap species: differences in—Habitat, one terrestrial and one aquaticSize, one hand-size and the other made of trailing stemsGrowth habit, one upright and the other trailingMechanics, one employing hydraulics and the other internal pressure in the cellsSpeed, the Waterwheel being ten times fasterThere is no evidence the two plants are related. “It is thought that the waterwheel and the flytrap may share a common ancestor,” Mary Halton says in the BBC News article. “However there is no fossil evidence for what this ancestor might have looked like.”“This is one of the main questions in the carnivorous plant community,” says Dr Simon Poppinga, an author on the study.“Snap traps evolved only once in plants. There are two different mechanisms. Which one was first?“The second paper focuses on the design of the Waterwheel plant to come up with a biomimetics application: “Flectofold—a biomimetic compliant shading device for complex free form facades,” by Körner et al. in Smart Materials and Structures. Illustration from Curtis’s Venus flytrap, drawing from Botanical Magazine by William Curtis (1746–1799)Smart and adaptive outer façade shading systems are of high interest in modern architecture. For long lasting and reliable systems, the abandonment of hinges which often fail due to mechanical wear during repetitive use is of particular importance. Drawing inspiration from the hinge-less motion of the underwater snap-trap of the carnivorous waterwheel plant (Aldrovanda vesiculosa), the compliant façade shading device Flectofold was developed. Based on computational simulations of the biological role-model’s elastic and reversible motion, the actuation principle of the plant can be identified. The enclosed geometric motion principle is abstracted into a simplified curved-line folding geometry with distinct flexible hinge-zones. The kinematic behaviour is translated into a quantitative kinetic model, using finite element simulation which allows the detailed analyses of the influence of geometric parameters such as curved-fold line radius and various pneumatically driven actuation principles on the motion behaviour, stress concentrations within the hinge-zones, and actuation forces. The information regarding geometric relations and material gradients gained from those computational models are then used to develop novel material combinations for glass fibre reinforced plastics which enabled the fabrication of physical prototypes of the compliant façade shading device Flectofold.Readers may wish to score these two papers on their scientific value. The first one does produce original knowledge on the plant’s mechanics, but ends with a just-so story about evolution. The second paper yields a practical application that could improve our lives.Darwinian storytelling is so useless. Give it up, researchers! We don’t need an “evolutionary perspective” on everything. Give us the facts, and make something useful from what you learn to help your fellow human beings.(Visited 409 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

South Africa’s tallest structures and buildings

first_imgThere are 54 skyscrapers in South Africa that are more than 100m high, according to the Skyscraper Center global database. Of these, four are taller than 150m and one is over 200m. Most are in Johannesburg, but some feature in the skylines of Durban and Cape Town.As South Africa develops its economic status and infrastructure into the 21st century, more skyscrapers are being planned or are already under construction, all set to rival and eclipse these existing buildings in sky-scraping glory.But while these buildings are high, they are still not the highest man-made structures in South Africa.South Africa’s highest structuresVarious power station smokestacks around the country rank as the top nine highest structures in South Africa, ranging from 275m (the Lethabo, Matla and Kendal power stations) to 301m (the Sasol synthetic fuel plant in Secunda, Mpumalanga).Themost amazing #TVtowers : Hillbrow Tower in #Johannesburg#JHB #SouthAfrica (270m) pic.twitter.com/sUGLznRjfa— PROMAX Electronics (@PROMAX_news) May 27,2016Johannesburg’s iconic Hillbrow Tower, now known as Telkom Tower, is the 10th highest structure – but the highest urban structure – at 269m.Assorted television transmission masts around the county also dwarf the country’s highest building, at 265m each.The 10 highest buildings in South [email protected] @AdeleRoberts on top of the tallestbuilding in Africa: carlton centre in Johannesburg #lastphoto pic.twitter.com/eNmTkc65Pv—Deano (@The5BallOver) August 15,2016Carlton Centre in downtown Johannesburg, built in 1973, is currently the highest building in the country, as well as the highest in Africa.

Mike Lutmer, July 25

first_imgShare Facebook Twitter Google + LinkedIn Pinterest It has been hot and steamy. We just baled some hay the other day and it had only laid two days and baled just fine. The ground where we are baling is really dry. West of us has gotten rain, south of us has gotten rain and we haven’t had any more than a few drops. It has been at least three weeks since we really had a good rain.I have some crops that really look good but it’s not going to be pretty if we don’t get some rain this week. The corn is just getting pollinating. Some of the later corn is just starting to shoot tassels and all of the beans are blooming. The double-crops look alright and little bit of rain would go a long way right now. There is a 30% to 40% chance today and another chance late in the week.Up in South Charleston, I heard they got five inches in 45 minutes last week. It sounded awful, but the crops were not too badly damaged. We don’t need a rain like that.We are trying to get the second cutting hay finished and go from there. It has been pretty favorable for making hay. Second cutting is starting to get a little thin because we haven’t been getting the rain. The stuff we made on Saturday, though, was beautiful.As a whole everything looks pretty good. We just need some rain. The corn looks decent and the beans are coming along. All of the wheat is done and the straw is all but baled around here. There was a good amount of straw, but it remains to be seen how long it will last. There has been a shortage of straw the last couple of years because it has been so wet. There are a lot of bales this year and the quality seems pretty good.last_img read more

Thoughts for Video Pros: Embracing the Amateur

first_imgIn this post, we share a few thought on why amateurs are here to stay…and why the professional community should embrace them.The word amateur refers to someone who does something without getting paid for it….however it has also more commonly been used to define someone doing something not very well. I’m a professional film editor because I get paid to edit and (hopefully) because I’m also good enough to be paid to do it. But the origin of the word amateur is actually from from the Latin word amator meaning ‘lover’. An amateur is someone who does it because they love to do it. They would do what they love even if they didn’t get paid to do it. As an editor I love to edit. I love what I do, getting paid is bonus (just don’t tell me clients that!)The Rise of the AmateurApple is a company that’s often accused of leaving their professional user base behind. “Where is the Mac Pro update” all professionals moan – releasing a powerful tower has come to symbolise their commitment to a pro user base after the fumbling of the FCPX launch.Interestingly Larry Jordan blogged early in April about a pre-NAB quote from an Apple source:The week before the 2013 NAB Show, I had an on-the-record comment from Apple saying that they have sold more Final Cut Pro X seats than they sold Final Cut Pro 7, which was part of Final Cut Studio (3). I was not given any more specifics than that. Why is this interesting?The bigger a user base gets the more a company has invested in keeping that user base happy. Amateurs like the idea that they’re using the same kind of software that the professionals use, but probably won’t invest the time (or money) it takes to get used to something like Avid Media Composer. By making FCPX more accessible to more people, Apple will need to continue to add features that the pros need for the kudos of a pro product, as well as maintaing a broader sales base. Adobe are also making it easier for amateurs to access their software with their Creative Cloud monthly app rental model.  Instead of shelling out over a grand for a full suite of professional creative software, its easy to give a project a go without the financial commitment. Whatever you think of FCPX the stats don’t lie, consumers are buying it and professionals are too. Phillip Hodgetts, creator of Sync-N-Link, reports more evidence of another tipping point.  Purchases of this professional video product for FCPX have surpassed previous sales of Sync-N-Link for legacy FCP versions.Why Pros Shouldn’t Fear the AmateurThe common insecurity among professionals is that this rising army of ‘kids with laptops’ will take away all the work – the “we don’t need a DIT, my nephew can do it” mentality. I think this fear is really unfounded for two reasons.First, the content most ‘amateurs’ are creating isn’t competing with the content that most professionals are creating. The video content explosion shows no signs of abating with an estimated $37 billion global video market in 2017. That’s a lot of pie to go around.  Professionals are typically given bigger budgets and more resources to create a higher quality of work.  The production value between amateur and professional video projects is obvious in most cases.Second, there is far more to being a professional than knowing how to use the right tools. Would you trust a teenager to be responsible for the safe guarding of the cumulative output of thousands of dollars worth of time and investment (your rushes) rather than an experienced and proven professional DIT? Probably not. Experience and expertise comes from years of practice that cannot be short-circuited by any number of free online tutorials. Professional levels of service, facilities and infrastructure are not to be sniffed at.Why You Should Embrace the AmateurImage source: FlickrSo as a professional, what should I do with these amateurs?We should embrace them. Embrace them because they represent a hungry, eager and cash ready community who are doing what they do not because they have to, but because they love to.What if you were to open up your shop after hours for short courses in teaching amateurs valuable tips and techniques in what you do? Or if you’re a rental house – hosting a day long saturday course where they can get hands on with professional equipment in partnership with a friendly supplier?Amateur may buy gear or equipment this is overkill for their needs….but they bought it and they want to know how to use it. Why not use this as an opportunity.  Be the teacher who shows them how.last_img read more

Royal Canadian Legion releases digital version of the Remembrance Day poppy

first_imgOTTAWA – The Remembrance Day poppy has entered the digital age.The Royal Canadian Legion launched a digital version of the distinctive red flower Friday, which it says can be customized, shared online and used as a profile image on sites including Facebook, Twitter, Instagram and LinkedIn.The downloadable image looks like a silver coin with a red poppy at the centre. The words “Remembrance Day 2018” run along the top edge, while the bottom edge can be customized to display the name of a veteran or someone in service. Otherwise, the words “We Remember” will appear.The Royal Canadian Legion’s deputy director says he hopes it will appeal to younger generations accustomed to communicating on social media.“It’s the way they communicate to their friends and to groups of individuals and it’s the same as physically wearing a poppy and saying, ‘I support veterans,’” says Danny Martin.He also expects a downloadable poppy would address our “increasingly cashless society,” guessing that a growing reliance on debit and credit purchases mean shoppers often have less cash to donate when faced with a request.In the same way there are strict rules around how a lapel poppy should be worn (over the heart, with the original pin), there are limits to how the digital poppy should be used.Martin says they’re not meant to be altered, and although they can supplant a profile image on a social media account, they’re not meant to be combined with other images.The danger that the poppy can be co-opted and distorted is why the legion is fiercely opposed to creating a poppy emoji, he adds, despite the popularity of miniature images in messages and email.“It’s a free-for-all. People can take that emoji and utilize it for other purposes, which happens all the time in different environments or different companies,” he explains.“You send that thing out in the common domain, then we’ve lost control and we actually, legally, (would be) losing control of the poppy trademark.”Still, he admits there’s “no doubt” someone could manipulate the digital poppy that’s being released now.“Yes, there’s going to be cases where they’re going to abuse the symbol or try and use it for their own cause and we’ll have to deal with that as we go along.”Poppies are meant to be displayed from the last Friday of October until midnight, Nov. 11.Beyond that date, an accompanying link to the online poppy will expire, although the image will remain on sites they’ve been posted to or drives to which they’ve been downloaded, says Martin.The digital poppies are available for an online donation at www.mypoppy.ca until Nov. 11 and are meant to complement the traditional lapel poppy, typically available at cafe and convenience store cash registers alongside a donation box.Martin says the legion is also selling a butterfly clasp that for the first time is allowed for use with the lapel poppy to better secure it in place.Publicity material for the digital poppy featured endorsements by celebrity Canadians including Margaret Atwood, Ashley Callingbull and Don Cherry, who dedicated his poppy to his great uncle, Sgt. Thomas William MacKenzie. He died in battle four days before Armistice Day in 1918.— Cassandra Szklarski in Torontolast_img read more
