Indigenous Peoples Front of Tripura (IPFT) MLA Dhananjoy Tripura has tied the knot with the girl who had alleged that he raped her on the pretext of marrying her. The wedding is the fallout of hectic negotiations between the families of the MLA and the girl, who hails from Mandwai, at the intervention of some senior IPFT leaders.Police had booked the Mr. Tripura (29) under sections of 417 and 376 of IPC after the tribal girl in her complaint with the police on May 20 last charged him with raping and deceiving her with the promise of marriage.Police made progress in the investigation amid pressure from different social forums for a fair and complete probe.Sources in the IPFT said senior leaders intervened for an amicable solution between the families as police were to arrest the MLA anytime. Mr. Tripura, who had vehemently denied the allegation, finally relented.The marriage was solemnised at a simple ceremony attended by only family members. Both the bride and the groom made a joint submission to the designated court seeking the closure of the case.
A captain plays what is, in his own words, the best Twenty20 innings of his life, his team gets a rare victory, and suddenly it runs into the most well-oiled machine in the tournament. That is what awaits the Delhi Daredevils when they take on the Mumbai Indians in the Indian Premier League (IPL) at the Wankhede Stadium here on Saturday.Virender Sehwags masterful 119 against Deccan Chargers in Hyderabad on Thursday was perhaps the innings of the tournament so far, given the magnitude of the target, Delhis lacklustre start and the fact that the next highest contribution to the cause was James Hopess 17 not out.However, it will be up to Sehwag to do it again, since the Daredevils run so far shows that only when he succeeds do they have a chance of winning. The Nawab of Najafgarh has fired on all cylinders three times – registering scores of 119, 80 and 77 – and on each of those occasions, Delhi have ended up victorious.Their only other victory – against Pune in Navi Mumbai – also featured a short Sehwag blitz, though there were solid contributions from David Warner and Venugopal Rao too.Warner, who missed the last match, is expected to be back in the scheme of things.According to the skipper, hardly anybody is expecting Delhi to make the play- offs in any case – just the kind of lowpressure scenario their inexperienced and inconsistent line-up needs.Not much improvement can be expected of the bowling – this being Twenty20 after all – though that has been Delhis stronger suit in any case. It is the fielding that will give coach Greg Shipperd something to work on, since the Daredevils players – old and young – have been guilty of letting the opposition score much more than they should thanks to sloppy ground fielding and dropped catches.advertisementAt the other end will be the master and his bunch of match- winners, who have only lost twice to lead the points table.Be it Tendulkar, who has led the way with remarkable consistency, Ambati Rayudu, who has looked every inch the prospect he was once said to be, or Rohit Sharma, who seems to change gears every time he spots the acronym ‘IPL around the ground – the batting has seldom been worrisome.Tirumalasetti Suman too played a sterling hand against Pune Warriors on Wednesday, while the big guns like Kieron Pollard and Andrew Symonds have hardly been called upon to unleash their brute force.But even more than the batting, it is their bowling that would give Delhi nightmares. They came up against Mumbai at the Ferozeshah Kotla in their first match of the tournament and Lasith Malinga duly served up yorker after yorker to end with figures of five for 13 and sent the Daredevils crashing to 95 all out. He is the leading wicket- taker in the tournament with 22, a mind- boggling 10 clear of the chasing bunch. Harbhajan Singh and Munaf Patel too have been extremely hard to get away, with economy rates of 6.24 and 6.19 respectively, and the rest of the bowlers have been protected well by the spectacular fielding Mumbai have put on display.It looks like another mismatch on the cards but it will be interesting to see how Tendulkar and his think- tank curb Sehwag, since getting him early could hand them the match on a platter.shreyas. sharma@ mailtoday. in
The growth has been bolstered by what Considine calls a “soft rollout.”American Googlers were coming to the U.K. version in droves, she says, but the format wasn’t ideal for them There was opportunity to improve.Studying the patterns and conducting audience research, the U.S. site has changed obvious elements-pricing items in U.S. Dollars instead of British Pounds, for example-along with some more obscure features-“The word ‘flavor’ has a ‘u’ in the U.K., so we had to make sure we took that out,” Considine says.To this point, expansion plans have, of course, been based on market considerations, but location has been a factor as well. With an October launch in Australia-the third TechRadar site-the site’s network is now staffed 24 hours a day.Breaking stories originating in the U.K. will be passed off to TechRadar staff in San Francisco at around 7 p.m. GMT. In turn, the Australian staff will pick up where the San Francisco team left off when they go home at 7 p.m. PT, and so on.South America has been posited as the next market, although Considine could not confirm whether plans had advanced past the testing stage.PlayStation: The Official Magazine Shutting DownDespite the success of TechRadar, another Future property, Playstation: The Official Magazine, will shut down after the holiday issue is released this winter.An official statement will not be released.The shuttering of PTOM comes months after Future announced that it would also cease publication of Nintendo Power at the end of the year.”It’s not the space, I think that the space is amazing,” Considine says. “We’re just going through a console life-cycle change, so you’re really just seeing the space in general is evolving, and I actually think it’s only going to get better.”PTOM and Nintendo Power have been in publication since 1997 and 1988, respectively. PTOM has a circulation of 139,000, according to Future.To stay updated on the latest FOLIO: news, become a Facebook fan and follow us on Twitter! It was a mixed week for Future plc who announced record growth for TechRadar’s U.S. website, while also revealing that it would close long-time gamer title, PlayStation: The Official Magazine.Just six months after its launch, Future’s U.S. incarnation of TechRadar.com reached 5.4 million unique visitors in September, surpassing the established U.K. site audience by more than 1 million. Although the size of the markets varies greatly, Rachelle Considine, Future U.S. COO, is happy with the results.”I don’t think we expected to grow this quickly,” she says.
Print still plays a role, but Hanley Wood has committed to a future based on digital media, data services and events. As such, the company is “shifting resources” toward those ends and away from print.The b-to-b publisher focused on the professional construction and design markets has laid off 19 employees from across various disciplines that will impact two of its top titles, Builder and Remodeling.CEO Peter Goldstone confirmed the moves in comments to FOLIO:.”[Hanley Wood] is making significant investments in digital and data solution platforms, increasing headcount across the board,” he says, noting that the company has made 70 hires in the last 12 months. “The shift in resource deployment is from print to digital and data. Our digital and data businesses are up 20 to 30 percent [year-over-year]. We are fueling the growth businesses with additional resources.” Goldstone says frequency and size of the print products will remain unchanged despite the cuts. Print and digital editorial operations began merging in 2011.”We are very committed to print as we still have over 20 print brands that are performing well against our core audience sectors,” he says. “Our core asset is our construction audience database. Print is still 50 percent of our overall media expense and critical to feeding the database.””Instead of wide and thin, which is the old magazine model,” Goldstone continues, “we are expanding vertically and deep within our core audiences. This specialization requires new talent and new skills and new training.”Hanley Wood has emphasized digital- and data-first approaches with several of its smaller brands and in many of its senior-level hires—the company brought on dedicated presidents of content, digital and market intelligence—but hadn’t made major changes to its primary print products until now.Two of the company’s three biggest magazines, Builder has a total qualified circulation of 111,716, while Remodeling has 102,035 qualified subscribers, according to the most recent BPA audits from the first half of 2013. The brands’ web properties attract 161,235 and 87,621 unique visitors each month, respectively, per their media kits.Broadly, the titles’ sector has declined, but is slightly outperforming industry averages in ad pages and ad revenue, according to the latest BIN report from ABM. Building, engineering and construction magazines declined 5.9 percent in pages and 3.7 percent in revenue through the first quarter of 2013.The layoffs are the latest in a series of changes Hanley Wood has undergone as it transforms its business model. The company has been sold twice since 2005 and drastically reduced its debt through restructuring early 2012. Goldstone, who had been president of Hanley Wood from 2009 to 2010, was named CEO last year.**Editor’s note: A prior version of this article incorrectly stated that Goldstone had served as Hanley Wood’s CEO from 2009 to 2010.
News GRAMMYConnect Presents: 6 Degrees From Brandi Carlile 6 Degrees From Brandi Carlile With GRAMMYConnect grammyconnect-presents-6-degrees-brandi-carlile We put the seven-time GRAMMY nominee together with GRAMMYconnect.com for an IBM Watson-fueled exploration of the talented and powerful people who contributed to her careerthe GRAMMYsGRAMMYs Feb 5, 2019 – 11:36 am Over the course of their careers, GRAMMY-nominated artists intersect with hundreds—maybe thousands—of fellow musicians, producers, and other industry professionals. Many have a chance to work with entertainers outside the music industry, or even a politician or two.Given a typical GRAMMY-nominated artist’s far-reaching network, we thought it would be fun to explore a few of these connections with folk-rock singer/songwriter Brandi Carlile, who is nominated for six GRAMMYs this year. To help facilitate the conversation, we used GRAMMYconnect.com, our AI-powered site developed in partnership with IBM.”It was really cool to kinda stroll dowm memory lane and see so many of the people that have touched my live over the years,” says Carlile. “I even came across a few connections I didn’t know I had.”One of those hidden connections was with none other than Amy Schumer, the comedienne, actress, and activist who shares a passion for many of the same causes as Carlile. Turns out Schumer and Carlile were born on the same exact day: June 1, 1981. “I think it’s quite a compliment to share a birthday with somebody that exciting and funny, and of that depth,” says Carlile. The two actually met one time at a hotel swimming pool, when Brandi’s wife managed to get a laugh out of Schumer. “She made the funniest woman in America laugh.”Exclusive: Brandi Carlile On ‘By The Way, I Forgive You’ & “The Joke”That’s not the only surprising link GRAMMYConnect found to Carlile: The Washington-born singer also has deep ties to former President Barack Obama. Obama has included a few of Carlile’s songs on the favorites list he posts every year. Not only that, but he wrote the foreword to Cover Stories, Carlile’s 2017 album to benefit children of war.“I’ve got a lot of connection points with Barack Obama over the last eight to 10 years,” says Carlile. “There are so many ways he’s impacted my life… I think the most potent connection I have to him is that I proposed to my wife on the day that he came out as the first American president in support of marriage equality.”And here’s one that many of you probably missed: Brandi is connected to Bradley Cooper and Lady Gaga, due to her cameo in A Star is Born. In the scene, Cooper’s character, Jackson Maine, participates in a GRAMMY Awards tribute to Roy Orbison. Brandi plays herself, and takes the lead on vocals in the scene. We also explored Carlile’s connections to Dolly Parton, who will be honored as the 2019 MusicCares Person of the Year at the L.A. Convention Center two nights before the 61st Annual GRAMMY Awards. Click Dolly’s name to find out how the two are connected! And while you’re at it, find out how Carlile connects to GRAMMY winners Pearl Jam, Elton John, Kacey Musgraves and Maren Morris.To explore more of Brandi’s connections, or the connections of more than 19,000 GRAMMY-nominated artists through the years, go to GRAMMYconnect.com.

It’s a thin band with a physical button on the side.Both have touchscreens, although the Charge 3 has a monochrome display compared to the Versa’s color LCD. You can swipe across from the sides of the display to access fitness tracking features or settings. To go back, press the side of the Charge 3. The Versa has three physical buttons that let you go back, start or stop activities, and make selections.You can change the watch faces on both in the Fitbit app. But the Charge 3 has fewer watch faces to choose from than the Versa, which has plenty of third-party options.Change the straps with this toggle on the Versa (left) and button on the Charge 3 (right). Angela Lang/CNET I found it hard to see the display on the Charge 3 in direct sunlight, regardless of the brightness setting selected (you can choose between auto or normal brightness). For me, the Versa was easier to see outdoors and you get an extra brightness setting to choose from.To change up the look of your Fitbit, each offers interchangeable straps. The Charge 3 has quick release buttons at the back, while the Versa uses a small metal bar that you have to toggle to change the strap. It’s a lot easier to swap the straps out on the Charge 3 than it is the Versa, especially if you’re looking for a quick change.Each display is coated in Gorilla Glass 3 to protect against scratches and bumps.Winner: Tie, depending on which size you preferFitness tracking features are similar on bothBoth Fitbits have an optical heart rate sensor, sleep tracking, female health tracking and water resistance to 50 meters. Neither has GPS built-in. Instead, they use connected GPS. So if you want to track your route, pace and elevation during an outdoor workout, you’ll need to take your phone with you.Check out your previous workouts from the Fitbit app. You can also tap into each one to see a breakdown of heart rate zones and calories. Tracking a run will also show a breakdown of your average pace. Screenshot by Lexy Savvides/CNET They both have automatic workout detection, and you can set goal-based exercises to get a notification once you pass a set distance, time or calorie goal.The Charge 3 lets you put six different workout shortcuts on the exercise screen, while the Versa gives you space for seven shortcuts. You can choose from 19 workout types from the Fitbit app (run, hike, walk, swim, bike, spinning, pilates, interval workout, golf, elliptical, weights, workout, treadmill, stairclimber, yoga, tennis, kickboxing, circuit training, martial arts, bootcamp). Both give you reminders to move, prompting you to complete a number of steps an hour to “win”.I found the fabric and plastic Fitbit straps fairly comfortable to work out with during a run or sweaty Pilates session.Thanks to its larger screen, the Versa gives you more metrics from your workout once you complete your exercise routine. It’s also the only one that lets you go back and view your past few workouts from the watch face, rather than diving into the Fitbit app itself.The Versa has lots of third-party apps available (which we’ll cover in the next section) which makes it easier if you prefer to track your workout in a different app. During workouts, I found the Charge 3 often gave a higher reading on my heart rate than the Versa. During an outdoor run, it said my maximum heart rate was over 200 beats per minute. From using previous heart rate trackers and smartwatches (and comparing with the Versa), running at the same intensity on the same route never gave me a max heart rate over 190.The Versa comes with the Coach app. A bit like a personal trainer on your wrist, it runs you through a sequence of moves with quick visual cues on the screen. It’s a nice extra if you want to squeeze in a quick workout. For similar workouts on the Charge 3, you’ll need to use the Fitbit Coach app on your phone.Fitbit metrics don’t sync to Apple Health, so keep this in mind if you are an iOS user who likes to consolidate data in one app.Winner: VersaBoth have smartwatch features, but the Versa does moreIt’s easy to get notifications mirrored from your phone on each Fitbit, and they both work with iOS and Android. That being said, you’ll only be able to respond to notifications if it’s tied to Android. You can customize quick responses to messages from the Fitbit app.Fitbit Pay is a mobile wallet that lets you tap to pay with NFC at compatible terminals. It’s only available if you buy the special edition of both (which does come at a premium). Angela Lang/CNET The Versa is the only one that can store music. It has space for around 300 songs, but the process to get those tunes onto the watch is cumbersome. You need to download a desktop app then make sure the Versa and your computer are on the same Wi-Fi network to start the transfer.If you prefer a streaming service, the only two options available are Pandora and Deezer, as long as you have a subscription. There is a third-party Spotify app available, but it is only to control playback from your phone.There are also many more third-party apps available on the Versa than there were when it first launched. Here’s a list of some of our favorites. The Charge 3 doesn’t have third-party apps at the time of writing.As the Versa was released in April 2018, a new edition of the watch potentially called Fitbit Versa 2 may be around the corner. We don’t have any insider information, but we’d love to see on-board GPS and Fitbit Pay integrated into the new version.Winner: VersaBattery life is stellar on the Charge 3There’s no contest here. You’ll get around six to seven full days on the Charge 3 before you need to juice it up, while the Versa gives you around four full days. Each has a proprietary clip-in charger. If you’re coming from the Charge 2, the cable for the Charge 3 is different.Winner: Charge 3What about price?At the time of writing, the Charge 3 costs $150 for the regular edition and $20 more gets you the special edition with Fitbit Pay and extra bands. The Versa is $200 and the special edition, also with Fitbit Pay, costs $30 more. Since the Versa was released almost a year ago, it has been discounted several times to a price that’s pretty comparable to the Charge 3 (the cheapest we’ve seen it in the past is $90).So comparing the Charge 3 and the Versa on price isn’t always straightforward, as you can get them for around the same price at certain times of the year.Winner: TieWhich is the best Fitbit for me?If you want Fitbit’s top of the line fitness tracker with a heart rate monitor and without too many bells and whistles, get the Charge 3. The battery will last you a long time and you’ll get notifications mirrored from your phone.If you’re looking for a smartwatch with a big screen, more robust fitness tracking on the watch itself, and the added bonus of a personal trainer on your wrist, get the Versa.

(Left) A photograph of the PENG, (center) the PENG powers an LCD for more than 60 seconds, and (right) a green LED is powered by a Li-ion battery that was charged by the PENG. Image credit: Yang, et al. ©2012 American Chemical Society Explore further The scientists, Ya Yang and Sihong Wang from the Georgia Institute of Technology in Atlanta, Yan Zhang from the Georgia Institute of Technology and the Chinese Academy of Sciences in Beijing, and Zhong Lin Wang from both institutions, have published a paper on a pyroelectric nanogenerator in a recent issue of Nano Letters.The scientists call the device a pyroelectric nanogenerator (PENG) because it’s based on the pyroelectric effect, in which an anisotropic material’s polarization changes in response to temperature fluctuations, which can be used to harvest thermal energy. Unlike the Seebeck effect, which is used to harvest thermal energy based on the temperature difference between two ends of a device, the pyroelectric effect occurs in environments where the temperature is spatially uniform but changes over time.”Wasted heat is a rich source of energy that can be harvested,” Zhong Lin Wang told Phys.org. “In 2010, for example, more than 50 percent of the energy generated from all sources in the US was lost mainly in the form of wasted heat, which presents us with a great opportunity to harvest this type of energy using nanotechnology. Harvesting thermoelectric energy mainly relies on the Seebeck effect, which utilizes a temperature difference between two ends of the device for driving the diffusion of charge carriers. The presence of a temperature gradient is a must for the conventional thermoelectric cell. However, in an environment where the temperature is spatially uniform without a gradient, such as the outdoors in our daily life, the Seebeck effect is hardly useful for harvesting thermal energy arising from a time-dependent temperature fluctuation. In this case, the pyroelectric effect is the choice, which is about the spontaneous polarization in certain anisotropic solids as a result of temperature fluctuation, but there are few studies about using the pyroelectric effect for harvesting thermal energy.” More information: Ya Yang, et al. “Pyroelectric Nanogenerators for Driving Wireless Sensors.” Nano Letters. DOI: 10.1021/nl303755m (Phys.org)—The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new area of research is that scientists have yet to find a method that can harvest very large amounts of energy. However, the technology is steadily improving, as demonstrated by the development of a nanogenerator that can partially charge a Li-ion battery by harvesting energy from temperature fluctuations in the environment. Ancient effect harnessed to produce electricity from waste heat Journal information: Nano Letters To date, PENGs have had output voltages below 0.1 V and current below 1 nA, which are too low to drive any commercial electronics. Here, the researchers demonstrated that a PENG made of a lead zirconate titanate (PZT) thin film has an output voltage of up to 22 V, a current peak of 430 nA, and a current density of 171 nA/cm2 when exposed to a temperature change of 45 K at a rate of 0.2 K/second. The PZT thin film is 21 mm long, 12 mm wide, and 175 μm thick – about half the size of a postage stamp.With these improvements in voltage and current, a single output pulse of the PENG could continuously power an LCD for longer than 60 seconds; in comparison, a piezoelectric nanogenerator, which harvests mechanical energy from the environment, can power an LCD for about 2 seconds. To expand the potential applications of the PENG, the researchers wanted to store the electric energy it generated from temperature fluctuations. So they hooked it up to a Li-ion coin battery, and demonstrated that the PENG could charge the battery from 650 to 810 mV in about 3 hours. They then showed that this stored electric capacity could be used to power a green LED for a few seconds.Another potential application of PENGs is wireless sensors. The researchers explained that wireless sensors can be powered by a rechargeable Li-ion battery with a voltage of 2.8 V. However, the PENG fabricated here has too small of a current to do this, since the current cannot completely overtake the battery’s inherent self-discharge. The researchers predict that doubling the area of the PZT film would double the current, and increasing the thickness of the PZT film could also increase the current. These improvements could make the pyroelectric nanogenerators attractive for driving wireless sensors, LCDs, and other small electronic devices, just by harvesting the temperature changes in the environment.”In our living environment, temperature change can come from an air-flow-induced drop in room temperature, the cycled heat generation near an engine, sunlight illumination with a moving shadow, on and off hot water/air flow in a pipe, etc.” Zhong Lin Wang said.Currently, the researchers are continuing to improve the PENG’s output power and are also integrating the technology with some existing products to demonstrate its practical applications.

JD Institute of Fashion Technology officially launched Tarun Shienh, CMD Premia Group as the mentor for the students of interior design at Eros International Continental recently. The event witnessed the association of two eminent personalities, Shienh who is a renowned name in the field of real estate and RC Dalal who is a pioneer in the field of design education. Rohit Bal, mentor for Fashion Design department at JD Institute also graced the occasion. Also Read – ‘Playing Jojo was emotionally exhausting’Shienh would be closely working with the student designers of interior design department and would absorb them in the industry. Talking about the event the mentor said, ‘I am very excited and honoured to be a part of JD Institute of Fashion Technology. The Indian interior infrastructure sector is growing at a CAGR of 5-7%. Employment of interior designers is expected to grow 19 percent till 2018, faster than the average for all occupations. This gives immense opportunities and scope for one to make a career in interior design. My aim is to enhance knowledge about the industry, design, layout, material selection and market intelligence’.Dalal said having Shienh is a great way to boost the learning and the exposure of jediiians. ‘We wanted to raise the bar for student designers and give them an experience of live projects, while also enabling them to get insights about the industry,’ he said.
