Share with your Friends:More 4. Resolve to change a habit.If New Year’s Eve is the night to kick off a new personal health habit, then Earth Day should be the day that kicks off a habit that helps you be a better environmental guardian. Perhaps this means taking half the time to shower as you normally do, or considering the environmental impact of the production of the food you eat and making some changes.5. Retrieve your archived caches.This one’s a must. Maybe you archived your cache a few months back and haven’t had “a chance” to pick it up yet. Put away the guilt and GO PICK IT UP!6. Go outside.When’s a good time to go outside? After you’ve finished reading the last word of this article. Seriously. The more time you spend outdoors, the more you’ll understand why it’s important to care for our natural spaces. Invite a friend, the kids, or the dog for a walk. Breathe in and out. Ready, set, GO.Happy Earth Day everybody! There has never been a better day to care for the geocaching game board (our planet!) than today — regardless of whether you live somewhere that celebrates Earth Day. Take a moment to think about the most beautiful place you’ve ever gone geocaching. Got it? Now consider: will that place continue to exist without the efforts of people who care for it? How can you be one of those people?The answer may depend on the space you thought of and your situation in life. But here are six suggestions to jump-start your contributions this week…and beyond.1. Sign up for a CITO event this weekend.Not only is attending a Cache In, Trash Out (CITO) event a great way to give back to our planet, if you attend one this weekend you’ll also earn a souvenir for your geocaching profile. Find a CITO event near you. 2. Find an EarthCache near you.“Education is the most powerful weapon which you can use to change the world,” said Nelson Mandela. What better way to heed his words than by finding an EarthCache and learning something new about a geological “cache” the earth has stored.3. Do some human-powered caching.If you normally drive a car when you go geocaching, think about how you could change things up to lower your ‘caching carbon footprint. Are there geocaches within walking or biking distance that you haven’t found? Maybe it’s time to figure out the public transit system and use it to find some city ‘caches. Think about finding some geocachers in your area and carpooling with them on geocaching trips!

In this NLE showdown, we compare the text and title generators in Adobe Premiere Pro and DaVinci Resolve — and there’s a clear victor.Earlier this year, I attended London’s VidCon with Blackmagic to demonstrate Resolve to the passing youngsters — or as many companies view them, the customers of tomorrow. Both Adobe and Blackmagic had a presence at the convention to promote their software to the up-and-coming content creators. While many young creators care little about 12-bit footage and RAW, they do long for quirky text functions. As I hear every weekend from my ten-year-old nephew, “Uncle Lewis, can you make me an intro for my YouTube channel?”So, how does each program measure up when examining title generators, built-in text effects, and pre-made presets?Resolve TextI will openly admit that I don’t like how DaVinci Resolve handles text. This is from my write-up Is DaVinci Resolve’s Title Generator a Hit or a Miss?:I love Resolve. It is, after all, a world-class color grading application, and the designers have made massive improvements with the NLE’s capabilities in 12.5 and in 14. However, the title generator is only standard NLE quality, despite a great-looking UI. It is great for simple location introductions, or to fade the name of an interviewee in and out. But for anything that is slightly creative, you’re better off working with a dedicated motion-graphics compositor.My main frustrations involved trying to do anything creative with text in Resolve. For example, in the still below, I have two text layers (because you can’t change the font size of one line in a simple fashion). One using the standard text generator, and the other using Text+. I’m able to move “The Beat” freely by simply selecting the text within the timeline viewer itself and moving the text to a new position. The PremiumBeat text, however, isn’t as easy. I must first select the text, then activate the transform tool, then move the text.Text+, which builds the text from a Fusion source, rolled out with Resolve 15, adding a number of creative controls with how the text operates — from animating the text with a write-on effect to rotating the text in z-space. Text+ also offers a lot more design choices by allowing you to adjust the shading of the color and the properties of the appearance, such as making the font appear as just a text outline.However (and again) frustrations arise when you realize that not all individual parameters have a reset function for when using Text+. And, even if you were to click Ctrl-Z to undo the action, nothing happens. It will only undo movement and font changes.From having to click through several menus to change specific properties of the text, to the tedious process of having to select the text on the track before changing the position in the timeline monitor, it’s not a fun process. We can’t forget what is perhaps everyone’s main grievance with Resolve and its text: when choosing a font, you don’t see a preview of the font’s design. You have to scroll through each font manually. (A Blackmagic representative stated in the Resolve Facebook Usergroup that this will be changing in the future.)While I have grievances with the simple text elements in Resolve, several 3D and 2D title presets were included with the incorporation of Fusion, last year. With these new titles, you can quickly drag and drop pre-made 3D custom titles to spice up your footage. Perfect for the content creator on-the-go.2D example:3D example:However, it does appear as if these presets are hard-baked into the software; therefore, you can’t customize the properties outside of the color elements.Many Resolve functions adjust with sliders rather than numerical inputs. While this isn’t inherently a negative attribute, I do find that the sliders respond a little too extremely. The slightest movement to the right can increase the text by 100 percent when you only want to move it 5 percent.Premiere TextIt’s no surprise that the company behind Photoshop offers an excellent text function in their editing software. A few years back, they removed the “add text object” and added a type tool similar to Photoshop. Being able to hit a keyboard shortcut (T) as opposed to opening the effects library, finding the title generator, and placing it onto a track is a lot more organic. And, if we want to talk about fluidity, the ability to just click on the text to move it is effortless. Of course, being able to adjust the size, font, and color of two lines of text in a single text object is a godsend. In Resolve, both lines of text would require separate text objects.Unlike Resolve and After Effects, Premiere doesn’t offer any built-in 3D text presets. As such, you would need to import them from After Effects. However, (and again) unlike Resolve, you can apply a vast number of video effects to the text object in Premiere — from transitions to the video effects themselves. In Resolve, if I were to apply a glow effect to a fusion title, it freaks out. (Although, it’s essential to note that you can apply effects to Fusion titles, but it has to be on the fusion page and added with the fusion effects.)If there’s one thing about Resolve that irritates me more than the text tool, it’s how it handles keyframes on the edit page. Whether audio, video, or text, keyframes are adjusted on the clip itself by opening the keyframe panel on the track. In Premiere, we have a separate window within the effects controls, which makes the process smoother and more efficient when animating text properties such as size or rotation.I’ve been trying to conjure something snarky to say about the type tool in Premiere, but there’s nothing to be said. It’s a simple, useful tool that’s easy to use. I haven’t edited in Premiere for over two years now, and despite pressing every incorrect keyboard shortcut, I was able to apply and animate the text quickly and with ease.I love using Resolve, and I think it’s the very best in many areas, however, text isn’t one of them. Despite not having custom presets or 3D text applications, Premiere wins this round for the simplicity of its text.Lewis McGregor is a certified DaVinci Resolve trainer.Looking for more articles on film and video editing?

The ruling Congress and Opposition BJP in Rajasthan have started the exercise for identifying candidates for by-elections to two Assembly seats — Mandawa and Khinvsar — scheduled for October 21. After facing defeat in the 2019 Lok Sabha election, the bypolls will be a challenge for the Congress, while the BJP pins its hopes on new State president Satish Poonia.The by-elections were necessitated after the sitting MLAs vacated the seats following their election to Lok Sabha. Mandawa MLA Narendra Khichar won as the BJP MP from Jhunjhunu, while Rashtriya Loktantrik Party MLA from Khinvsar, Hanuman Beniwal, won from Nagaur after his regional party entered into an alliance with the BJP and joined the NDA just before general elections.The candidates’ nominations can be filed till September 30 and the date for withdrawal of candidature will be October 3. After the polling on October 21, the results will be declared on October 24, according to the Election Commission.Impact on civic pollsThe by-elections are important for Congress because of their perceptible impact on the municipal polls due in November this year, for which the rival factions in the party wish to field their favourite candidates with the winning potential. Moreover, the party wants to send across a message of its effective governance even after its defeat at all the 25 Lok Sabha seats in the State.For the BJP, the appointment of Mr. Poonia — a Jat leader with strong association with Rashtriya Swayamsevak Sangh — as the party chief may help at the two Jat-dominated seats. The party is yet to make up its mind on entering into alliance with the RLP, though former Chief Minister Vasundhara Raje may not play a major role in the candidates’ selection, unlike in the Lok Sabha polls.Mr. Beniwal said on Monday that the RLP-BJP alliance would contest both the Assembly seats and he would like to field his party’s candidate in Khinvsar. “We are willing to support the BJP candidate in Mandawa. The final decision will be take at a meeting of office-bearers of both the parties in a couple of days,” he said.The Congress, which has strengthened its position in the State Assembly after the recent merger of six Bahujan Samaj Party MLAs, may give ticket to a member of Nagaur district’s influential Mirdha family. The party has lost the Khinvsar seat during the last three successive elections, as Mr. Beniwal won first on the BJP ticket in 2008 and later as an Independent in 2013 and as the RLP candidate in 2018.Mandawa was earlier considered a stronghold of veteran Congress leader Ram Narayan Chaudhary, who died in 2012. His daughter Rita Chaudhary defeated Mr. Khichar in 2008, but the latter emerged victorious as an Independent in 2013 and and as a BJP candidate in 2018.
Journalists in the Valley took out a protest march here against the continued suspension of internet services which completed 100 days on Tuesday since the abrogation of the Jammu and Kashmir’s special status on August 5.Scores of journalists working with different media organisations assembled at the Kashmir Press Club here and took out a protest march against the snapping of internet services in the Valley on the night of August 4, hours before the Centre revoked the state’s special status under Article 370 and abrogated it into two Union Territories.The journalists demanded immediate restoration of the services to facilitate the media persons to discharge their professional duties.“We took out the protest against the suspension of internet services for 100 days now. Internet is a basic took for journalists to discharge their professional duties and we demand its immediate restoration,” senior journalist Pervez Bukhari told reporters after the protest.The Centre’s August 5 decision led to an unannounced shutdown in the valley even as authorities imposed severe restrictions, including on communication, which were later gradually eased out.Postpaid mobile services on all networks were restored in the Valley on October 14, 72 days after they were snapped.However, pre-paid mobile phones and all internet services continue to remain suspended since August 5.The government has set up a ‘Media Facilitation Centre’ at a conference hall of a local hotel here for journalists to discharge their professional duties. But the media persons complain that it has not enough computers and they have to wait for hours for their turn.
She is over the moon after becoming the first Indian woman boxer to clinch an Olympic medal but bronze is not the colour for M C Mary Kom, who feels she could have finished higher on the podium had it not been for the “confusion” that gripped her during the semifinals.’Magnificent Mary’ as she is called by the International Boxing Association, was the lone Indian in fray when women’s boxing made its Olympic debut in the just-concluded London Games.Top 10 memorable moments from London OlympicsThe five-time world champion ensured a piece of history for herself and the country by fetching a bronze in the flyweight 51kg division. But for someone who is more used to finishing at the top, bronze was less than satisfactory.”I am very happy to be the first Indian woman boxer to get a bronze medal but I am sad that I could not convert it into gold. I don’t know what happened during my semifinal bout. My body was not moving the way I would have liked and I felt as if I could not do anything. I was very much confused,” the 29-year-old, who returned to the country to a rousing reception early this morning, told PTI in an interview.Video: Mary Kom gets a rousing welcomeHundreds of cheering fans welcomed Mary Kom at the airport, breaking into an impromptu jig in which the boxer also participated. She was accompanied by her husband Onler Kom and her mother Akham Kom.Mary Kom lost 6-11 to England’s two-time world champion Nicola Adams in the semifinals and reflecting on the bout, the diminutive Manipuri was at a loss of words to explain what went wrong.advertisement”I never get nervous before bouts but that day I don’t know what was happening to me. I can’t even explain it. I was not attacking as much and may be it was the crowd also which was cheering Nicola. I generally don’t get affected by how the crowd is behaving but probably in the semifinals, it affected me,” she recalled.The Indian conceded that Adams had the bout but was not quite convinced by the scoreline which she felt was narrower than what the record books show.”I don’t think it was that big a margin even though I admit that Nicola won it. At best, it could have been a difference of 2-3 points but certainly not 6-11. Even though my body was not moving that well, I think I hit her hard and I should not have lost by that margin,” she insisted.”I don’t think she hit me so many clear punches, hers was a touch-and-go game. I had already fought my toughest bout of the competition in the first round itself,” she said.The mother-of-twins was nevertheless happy that she returned to the country with a medal around her neck.”I think I have achieved everything that I dreamt of. Of course I wanted a gold medal at the Olympics but I am happy with the bronze too because I am the first Indian woman boxer to get it,” she laughed.However, realisation of all her dreams does not mean that Mary Kom is thinking of hanging up her gloves just yet.”I am planning to continue till the next Olympics in Rio de Janeiro. I don’t know if my body will allow this to happen but if it does, then I would surely try to get a gold there,” she said.Asked to compare her five world titles with the Olympic bronze, Mary Kom emphatically said that nothing can beat the thrill of being there on the podium at the biggest sporting show on earth.”This Olympic bronze is very, very special for me. Of course the world titles also mean a lot but an Olympic medal is at an altogether different level for every athlete in the world. It is the highest honour,” she explained.”It is a perfect climax to all the hardships that I have gone through during my life. God has been kind to me,” said the boxer, reflecting on a 12-year career during which she changed three weight categories since debuting in 45kg.
In the case of tennis, the popularity of the game in the metros, coupled with the success of Leander Paes, Sania Mirza, Mahesh Bhupathi and Somdev Devvarman has ensured a steady flow of young hopefuls taking up the game. The hosting of the CWG meant a massive makeover of the R.K. Khanna Tennis Stadium in the Capital. The stadium has 14 fields of play and the courts are utilised for approximately 10 hours.Nearly 500-600 youngsters practice every day and after the CWG, more than 20 tournaments, including Challengers and Nationals have been held here. The ‘Come and Play’ scheme of the Sports Authority of India (SAI) will also be implemented and 50 children have already been shortlisted for the programme. But the going has not been smooth for the stadium authorities as they do not get any funding from the government for the maintenance, and getting sponsors for the ITF tournaments is also an uphill task.”The maintenance of the stadium entails a lot of money and we do face some teething problems. But with players from Iran and Nepal also utilising the facilities with our national teams , we somehow manage to keep things going,” said R. Chauhan, Executive Director – Development and Marketing, All India Tennis Association.He also stressed the importance of conducting more tournaments. “We should conduct more ITF and Challenger tournaments. But funds are an issue. We are planning to submit a plan to the government and apprise them of the benefits of more tournaments. Our players will immensely benefit from it and their rankings will also improve if they play more Challenger tournaments in home conditions,” he added.advertisement

Share BILL ZEEBLE / KERA NEWSJosh Masters listens to Children’s Health licensed counselor Angeleena May using the hospital’s telehealth connection. Children’s Health now has more than 100 telehealth school partners.One in five North Texas children lives in poverty, and more than a quarter million are hungry as their parents struggle to feed them.Those are just a few statistics from a recent 97-page report issued by Children’s Health, the Dallas-based children’s hospital network. The study offers possible solutions, too.The Beyond ABC report only looks at the well-being of children in parts of North Texas, specifically six counties: Dallas, Collin, Denton, Cooke, Grayson and Fannin. It has come out every two years since the late 1990s.How health affects educationThe rate of uninsured kids in Dallas County, as well as Cooke, Fannin and Grayson counties is double the national average. The report says more than 500,000 Texas children lack health insurance, and nearly half of the kids in Dallas County kids are enrolled in Medicaid. The study finds children living in poverty are seven times more likely to be in poor or fair health.Health has a direct impact on education. Yet, low-income parents may be hesitant to get medical care for their kids for several reasons, including cost. Children’s Health points to its telemedicine program as a way to help.For example, if a child’s sick in school, he or she usually goes to the nurse. Then, the parent typically gets called, has to leave work, possibly lose pay, then get to a doctor’s office by car, bus or a friend. Dr. Stormee Williams, who oversees the telehealth program with more than 100 school partners, says telemedicine offers another option.“We can call in, have a live video interaction,” Williams said. “The nurse has an electronic stethoscope, otoscope, dermscope, so that, live, we can diagnose ear infections, look at the throat, listen to lungs in a child with asthma, and actually make a diagnosis and treat if necessary and send prescriptions, electronically.” Dallas’ problem with povertyThe report also finds one in five North Texas kids lives in poverty and offers another way to look at that. Nearly 500,000 children in North Texas qualify for free or reduced-price school meals. Food insecurity in all of the six counties in the study exceeds the national average.In the Dallas school district, 90 percent of the students are considered low-income.Mike Koprowski used to be with Dallas ISD, and while he’s concerned about the poverty rates in Dallas, he’s even more concerned about neighborhood segregation in Dallas. He calls Dallas one of the most segregated cities by race and income in the country.“When you have areas of concentrated poverty, that creates a lot of challenges in the school. So any educator will tell you a kid living in poverty brings challenges into the classroom,” he said. “But when an entire school building is concentrated with low-income kids, the challenges get more difficult.” Koprowski calls that segregation a disaster for Dallas.Proposed solutionsThe report recommends supporting increased development of mixed-income neighborhoods and more widespread acceptance of housing assistance vouchers.Some say lawmakers should get involved.Matt Moore, Children’s Health vice president for government relations, says elected leaders often say it’s important to improve the state of children, but they don’t necessarily take action.“So, I think that the interest is there; we see it from both sides of the aisle,” Moore says. “We see it among the deepest of red tea party members; we see it among the most blue of liberal members. The interest is there, but it just seems that, right now, the moment is aligned against us.”That leaves nonprofits, like the North Texas Food Bank, education groups and health care providers, playing a big role. The goal is to help kids get the basics for success when obstacles block the way. Dr. Williams says it all matters because she’s looking to the future. “We know that healthy kids learn better. And children who’ve learned well end up being healthier adults,” Dr. Williams says.The report also suggests that schools prioritize support for student health and healthy behaviors by providing more nutritious meals and more physical activity and focusing on students’ behavioral and emotional health.Read the full report 2017 Beyond ABC Report by KERANews on Scribd
© 2019 Science X Network Explore further A team of researchers affiliated with several institutions in Japan has found evidence that offers credence to a theory that subducted crust exists at the base of Earth’s upper mantle. In their paper published in the journal Nature, the group describes experiments they conducted in their lab involving pressurizing material believed to exist in the mantle, and what they found. Johannes Buchen, with the California Institute of Technology, has written a News & Views piece on the work in the same journal issue. Citation: Lab experiments offer credence to theory that subducted crust exists at the base of Earth’s upper mantle (2019, January 10) retrieved 18 August 2019 from https://phys.org/news/2019-01-lab-credence-theory-subducted-crust.html Credit: CC0 Public Domain More information: Steeve Gréaux et al. Sound velocity of CaSiO3 perovskite suggests the presence of basaltic crust in the Earth’s lower mantle, Nature (2019). DOI: 10.1038/s41586-018-0816-5 Journal information: Nature Prior research has suggested that as tectonic plates shift around, some of the material on the surface is pushed below. Prior research has also suggested that such material would likely sink deep into the mantle because it is denser than the pyrolite that is believed to make up most of the mantle. Researchers theorize that that the subducted material would likely settle in the bottom of the transition zone between the upper and lower mantle—but to date, there has been little evidence backing up this theory. The primary test has been analyzing seismic waves traveling through such material, but these readings have two possible explanations—the first is that differences in the speed of waves traveling through material in the area is due to dehydration melting. The other is that it is surface material that has drifted down into the mantle. In this new effort, the researchers report that they believe they have found evidence that supports the latter theory.The researchers started by noting that the crust beneath the oceans is made mainly of basalt. They also noted that prior research showed that when basalt makes its way into the crust, a mineral called calcium silicate perovskite (CaSiO3) is created. Thus, if crust material made its way to the transition zone, it would be in the form of CaSiO3. But CaSiO3 exists in two configurations depending on its environment—at high temperature and high pressure, it has cubic symmetry. At lower temperatures and pressure, such as on the surface, it has tetragonal symmetry. That meant the team had to subject a sample of the crystal to pressure and temperatures approximately equal to that found in the mantle to test it. Once they succeeded, they sent ultrasonic waves through it to see if they matched what theory had suggested. They found that the cubic form of CaSiO3 did, indeed, slow the waves in approximately the same way as they do when passing through parts of the mantle, suggesting that the material there is very nearly the same. And that suggests the material is, indeed, subducted crust. Subducting slabs of the Earth’s crust may generate unusual features spotted near the core This document is subject to copyright.
