first_imgQPR boss Mark Hughes is considering a loan move for Porto centre-back Rolando and will complete the signing of Brazil goalkeeper Julio Cesar from Inter Milan in the next 48 hours, the Daily Mail report.It is claimed Rolando has been targeted because moves for Michael Dawson and Ricardo Carvalho have stalled.Meanwhile, Liverpool boss Brendan Rodgers is planning a £15m swoop for Chelsea forward Daniel Sturridge, the Daily Mirror say.It is suggested that Rodgers is ready to sell Charlie Adam and Stewart Downing in order to fund the deal.He is said to be a big admirer of Sturridge, whose future at Stamford Bridge has long been the subject of speculation.Sturridge has made it clear he wants to play in a centre-forward role rather than the wide position he has operated in for much of his time at Chelsea.The Blues are reportedly aware of Liverpool’s interest but would be reluctant to sell unless they sign a striker before this week’s transfer deadline.The Sun say Chelsea want £25m for Sturridge and that Tottenham are also interested in him, while the Daily Mail suggest Rodgers has made an inital enquiry and will try to land the England international for £10m.Chelsea manager Roberto Di Matteo recently stated that he expected Sturridge to stay at the club.The Mail say Chelsea are tracking 23-year-old Montpellier defender Mapou Yanga-Mbiwa.Meanwhile, Tottenham could offer Jermain Defoe to Fulham as part of an exchange deal for Moussa Dembele, according to the Mirror.It is claimed that David Bentley and Jermaine Jenas could also be offered to the Whites as Spurs look to take Dembele to White Hart Lane.Tottenham’s apparent interest in the Belgian is also reported by The Guardian, while the Mail suggest Fulham are monitoring powerful Genk forward Christian Benteke as a possible replacement for Clint Dempsey.This page is regularly updated. Follow West London Sport on TwitterFind us on Facebooklast_img read more

first_imgWe continue examining findings that call into question the certainty of scientific consensus about global warming. Here are interesting papers from leading peer-reviewed science journals.Ozone depletion following future volcanic eruptions (Geophysical Research Letters). This paper concerns the ozone layer, another atmospheric phenomenon blamed on humans. What about volcanoes? “If HCl, a chlorine-containing compound often present in large quantities in volcanoes, were to reach the stratosphere following a future explosive eruption, substantial ozone loss could result, regardless of the year in which the eruption occurred.” Have humans really been the culprit?Satellite snafu masked true sea-level rise for decades (Nature). This data point seems to favor the consensus. “Revised tallies confirm that the rate of sea-level rise is accelerating as the Earth warms and ice sheets thaw,” Jeff Tollefson reports. The reason for the correction, however, might undermine confidence in other types of data gathering methods:Now, after puzzling over this discrepancy for years, scientists have identified its source: a problem with the calibration of a sensor on the first of several satellites launched to measure the height of the sea surface using radar. Adjusting the data to remove that error suggests that sea levels are indeed rising at faster rates each year.River networks dampen long-term hydrological signals of climate change (Geophysical Research Letters). Here’s another non-trivial factor that was not given adequate consideration in current climate models. [Anecdote: The Fraser River is shown in the salmon migration episode of the Illustra Film, Living Waters.]River networks may dampen local hydrologic signals of climate change through the aggregation of upstream climate portfolio assets. Here we examine this hypothesis using flow and climate trend estimates (1970–2007) at 55 hydrometric gauge stations and across their contributing watersheds’ within the Fraser River basin in British Columbia, Canada. Using a null hypothesis framework, we compared our observed attenuation of river flow trends as a function of increasing area and climate trend diversity, with null-simulated estimates to gauge the likelihood and strength of our observations. We found the Fraser River reduced variability in downstream long-term discharge by >91%, with >3.1 times the attenuation than would be expected under null simulation. Although the strength of dampening varied seasonally, our findings indicate that large free-flowing rivers offer a powerful and largely unappreciated process of climate change mitigation. River networks that integrate a diverse climate portfolio can dampen local extremes and offer climate change relief to riverine biota.Influence of shale-total organic content on CO2 geo-storage potential (Geophysical Research Letters). This paper concerns efforts to store excess carbon dioxide in shale rock, but indicates that how it stores the gas is poorly understood. Might natural carbon storage be more variable than thought?Shale CO2-wettability is a key factor which determines the structural trapping capacity of a caprock. However, the influence of shale-TOC [total organic content] on wettability (and thus on storage potential) has not been evaluated despite the fact that naturally occurring shale formations can vary dramatically in TOC, and that even minute TOC strongly affects storage capacities and containment security. Thus there is a serious lack of understanding in terms of how shale, with varying organic content, performs in a CO2 geo-storage context.Land surface albedo bias in climate models and its association with tropical rainfall (Geophysical Research Letters). This paper’s opening sentence undermines confidence in climate models by admitting, “The influence of surface albedo on tropical precipitation is widely appreciated, but albedo bias over snow-free areas in climate models has been studied little.” Even if modelers find ways to compensate for this factor, what other factors have been “studied little”?Glacial weathering, sulfide oxidation, and global carbon cycle feedbacks (PNAS). These authors found a negative feedback loop that could prevent runaway glaciation, so often worried about in the climate change literature. In addition, these researchers consider large climate changes over a million years, when man had nothing to do with big changes in global temperatures.Record Temperature Streak Bears Anthropogenic Fingerprint (Geophysical Research Letters). Despite the uncertainties and unknowns listed above, many climate scientists overstate their confidence that the consensus is right. A look at the statistical methods in this paper, however, shows a fair amount of selective data manipulation to come up with probability numbers that the authors infer point to anthropogenic causes. Then notice the lead author: Michael Mann, a staunch advocate of the consensus whom some conservatives feel is so tainted with political bias as to be untrustworthy.We think the public deserves to know how much error and uncertainty goes on behind the curtain of the science wizards. Think of the money and the global political fallout downstream of the trust world leaders put in the scientists modeling climate change. What if much of it is fake science? What if it impossible to gauge the extent to which humans are responsible? What if natural processes will warm the climate no matter what humans do about it? These are important questions. It’s not our place to decide human fault on this issue; we just report what we run across in the literature, and as you can see, a lot of it is much more uncertain than the media make it out to be. With our 20 years of experience watching a consensus overplay Darwinism, we have reason to doubt the credibility of scientists’ judgment on such a global, complex issue. And we certainly doubt their credibility as prophets! None of them will be around in a century to see whether their forecasts of warming will come to pass or not.(Visited 485 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_img RELATED ARTICLES Making net-zero energy financially attractiveNet-zero energy is achieved in four steps: (1) Identify on-site renewable energy capacity and thus set the district’s energy “budget;” (2) use superefficient district geothermal heating and cooling; (3) set design standards to drive load down to as little as 75% below code; and (4) iterate between steps 1 and 3, optimizing based on the net present value of the life-cycle cost until net-zero energy is achieved.These four steps must be done in a way that makes the project financially attractive to developers, tenants, and investors.Three things must occur to make net-zero energy financially attractive to parcel developers: (1) on-site solar photovoltaics should be owned and developed by a third party; (2) the capital cost of heating and cooling equipment should be moved out of buildings and into a district heating/cooling system; and (3) there should be on-bill financing for the incremental cost of energy efficiency. This puts first costs at or below the cost of a business-as-usual (BAU) building. On top of that, high-performance buildings typically yield higher sale prices or rents.To make net-zero energy financially attractive to tenants, the BAU tenant energy bill must be replaced by a net-zero energy bill that includes three components: (1) an electricity bill that includes the third-party-owned PV costs; (2) district heating and cooling costs; and (3) on-bill repayment of the energy efficiency financing. The sum of these three components is lower than BAU, and the tenant inhabits a healthier and more comfortable building.Net-zero energy business models are financially attractive to investors because the large capital investments in PV, district heating and cooling, and energy efficiency are repaid over time on utility bills, generating a steady return that benefits from enhanced credit because of the utility-customer relationship.The elements of this business plan can be broken into discrete components consisting of services and value streams. Some of these components are interdependent, while others stand alone. But in our newly released Insight Brief, “An Integrative Business Model for Net-Zero Energy Districts,” Rocky Mountain Institute (RMI) presents an innovative business model for developing net-zero energy or ultra-low energy districts and details how pursuing net-zero energy is not a cost, but rather a significant value driver.Our innovative business model develops net-zero energy districts in a way that is attractive to the district developer, parcel developer, and tenants; creates a profitable business for an integrated energy services provider; and benefits the local electric grid and neighboring community. It was developed specifically for a 180-acre development in a midsize U.S. city. By IAIN CAMPBELL Building better, cleaner communitiesDistrict-scale developments are uniquely positioned to be a major driver of the next generation of high-performance buildings and an intelligent electric grid, and to benefit financially from such leadership.Not all of the value elements of this business case will pertain to every large-scale development, given their variations in size, use types, regulatory environment, project goals, energy prices, access to capital, or operator sophistication. But stand-alone components or hybrids of this model can still be valuable, especially under the guidance of an IESP that plays an integrative role in value capture and creative financing, making such developments attractive to investors, developers, and tenants alike.Net-zero districts will be explored during October’s Getting to Zero National Forum in Denver, Colorado. View the program and register today. The Department of Energy Chooses a Definition for Net-ZeroCalifornia Leads the Nation in Net-Zero ProjectsMajor U.S. Builder Tests Net-Zero MarketNet-Zero versus PassivhausNet-Zero Families, Not Net-Zero HomesNet-Zero Cities Aren’t Possible, You Say?center_img A profitable business for integrated energy service providersDistrict-scale developments have a unique opportunity to put in place a dedicated integrated energy services provider (IESP) to manage multiple energy-related operations and act as a multipurpose developer, financier, operator, and administrator of energy systems, as well as a regulator of building performance requirements. The IESP may be one organization or multiple organizations acting in cooperation, but the key is to execute multiple functions in concert to achieve performance objectives in the most economical way.IESP functions include:1. Sales of electricityActing as an electrical micro-utility providing retail electricity to the district’s electricity customers, managing supply, and conducting customer billing. The IESP functions as an intermediary between the regional electric grid and the district’s microgrid, negotiating interconnection terms, ancillary services, demand charges, consumption charges, and feed-in tariffs with the regional utility.2. District heating and coolingHandling district heating and cooling through a central district heating and cooling system (geothermal heat pump systems being the most efficient). Compared to individual building plants, district heating and cooling is much more efficient, has lower maintenance costs, is more reliable, and has longer equipment lifetimes. Equally important to this business case, district heating and cooling shifts upfront capital costs from parcel developers to the IESP.3. Neighborhood diversityOptimizing heating and cooling across a diverse neighborhood building stock with a district heating and cooling system. Rather than designing individual building systems to meet individual-building instantaneous peak loads, a district system is designed to meet the collective peak load, which is considerably lower, due to non-coincident peaks across the diverse building stock. This means smaller overall system capacity and lower first costs.4. Demand-side managementThe IESP would manage multiple megawatts of load at the district heating and cooling plant, as well as introduce the possibility for additional thermal storage that would make the load even more flexible. Demand response capabilities in other building loads, such as lighting, water heating, or plug loads, would make that flexible, demand-side resource even larger. The importance of megawatts and “negawatts” at a district scaleRenewable supply is a critical component of achieving net-zero at a district scale, and it is necessary to optimize renewable energy deployment across the entire district to achieve the best economics. In this model, the IESP is responsible for all renewable energy development, whether on-site, such as ground-mounted, rooftop, or carport-mounted photovoltaics (PV), or off-site via power purchase agreements. It can then recoup the cost of the system via utility billing to customers.Depending on the regulatory environment, it can negotiate with the regional utility to capture maximum value from the large-scale, on-site generation, which could be in the form of net metering, feed-in tariffs, or simply wholesale into the regional spot market. Having one single solar developer means that on-site renewables can be phased and developed en masse, negotiating lower costs and capturing economies of scale in mass installations.The IESP also can manage the demand side, encouraging the deployment of high-performance buildings that benefit owners, occupants/tenants, and the environment through district-wide energy efficiency financing. Compared to conventional buildings, superefficient buildings (buildings that perform 50% better than code-compliant buildings) may cost more upfront, as a result of expert integrative design costs, higher-performance envelopes, smart controls, best-in-class systems, and rigorous construction quality, testing, and commissioning.But this incremental cost for superefficiency can be financed in the form of a loan from the IESP, removing any incremental first costs from the parcel developer. That loan can be repaid over time on utility bills by the electricity and district heating and cooling customers who are benefiting from the lower energy bills. The incremental capital investment, and resultant property value, of energy efficiency thus stays with the property. The IESP lender also has recourse or collateral against defaulting customers, making the on-bill financed loans more credit-worthy. Reducing demand at a district scale also significantly lowers the cost of renewable energy supply. Net-zero energy (NZE) buildings — those that are responsible for the production of as much clean energy as, or more clean energy than, they use annually — have been gaining momentum around the world. And now, even net-zero energy districts are being contemplated, like Fort Collins’s Fort ZED, Arizona State University, and UC Davis’s West Village. However, there still remains an industry-wide perception that net-zero energy is too expensive, or comes at a much higher incremental cost over business as usual.Master developers of NZE districts face the challenge of driving exceptional energy performance without deterring prospective parcel developers or incurring exorbitant development costs themselves. Prospective parcel developers may fear that stringent performance requirements will require higher upfront capital costs or that achieving ultra-low energy buildings will not be cost-effective in the long run, compared to business as usual. Prospective tenants of NZE developments may fear that additional construction costs will get passed through to them in the form of higher rents, or that the ongoing cost of procuring renewable energy may be higher than conventional energy bills. Iain Campbell is managing director of the Rocky Mountain Institute. This post originally appeared at the RMI Outlet.last_img read more

first_img JBL Flip The new JBL Flip 5 in front of the Flip 4. It’s really only a little bigger than its predecessor. David Carnoy/CNET Lay the JBL Flip 5 next to last year’s Flip 4 like I did at this year’s CES in Las Vegas and you’ll notice that the Flip 5 looks pretty similar but is slightly bigger than its predecessor. That increased size has allowed JBL’s engineers to equip the Flip 5 with a larger battery and more power so that it delivers a little bigger sound. It also now has USB-C charging for quicker battery charging. Like its predecessor, the JBL Flip 5 is fully waterproof, has a buillt-in microphone for speakerphone calls and comes in multiple color options. It’ll ship this spring for $100 and should gradually come down in price over the course of the year.I’ll have a full review shortly before it hits stores. jbl-flip-5-colorsEnlarge ImageAll the new color options.

first_imgSagarFour days since the death of Sagar, police have failed to arrest the main culprits of the murder. Accused of theft, teenager Sagar was beaten to death in Gauripur, Mymensingh.The police said that till Thursday they could not nab any of the six accused, including Akkas Ali, the prime suspect in the case.The police, however, arrested two men on Tuesday and Wednesday, Riaz Uddin and Fazlur Rahman respectively. In confessional statements, they told a court that hatchery owner Akkas Ali and his staff Qayyum beat Sagar to death.The four other accused in the case statement are Akkas’ brother Jewel, Hasu Miah, Sattar, and Sohel.Meanwhile, Sagar’s mother alleged that two unknown people came to their home in the slum around 12:00am on Thursday and woke them up from bed. When Sagar’s family asked them who they were, they remained silent and offered them Tk 10,000. But they did not reveal why they were offering the money.Sagar’s family refused to take the money.“They could have pressurised us to withdraw the case after giving the money. I don’t want money in exchange of my son’s life. I want justice,” said Sagar’s mother Hasina Khatun.Sagar’s father Shipon Miah said, “Sagar and I would run the family with our earnings. I’m now worried about how to run the family alone.”Sagar used to collect and sell garbage while his father sells cosmetics.Sagar, 16, was tied to an electric pole and brutally beaten to death at the Gauchhiya Hatchery of Char Sreerampur village in Gauripur, on allegations of stealing a water pump.Police recovered Sagar’s body from a bush near the hatchery on Tuesday.Sagar’s father lodged a case in this incident accusing six named and another six to seven unnamed people.Mymensingh police superintendent Syed Nurul Islam said they have taken the case seriously and vowed to arrest the accused soon.Read more: Teenager tied to electric pole, beaten deadlast_img read more

first_imgYouTube takes a 30% cut of membership fees. The program has been available on a handful of top channels via a “Sponsor” button during the trial phase. Over the next few months, it will be expanding to channels worldwide with more than 100,000 subscribers under the new name Channel Memberships.“There’s a subset of those huge audiences who are superfans who would love to be closer to the creators,” said Dhawan.YouTube channel owners can customize many different elements of their Channel Memberships, including designing their own emoji and badgets, and offering an array of content and merchandise bonuses to paying fans. “It’s a blank canvas,” Dhawan said.While for now the $4.99-per-month Channel Membership can’t be changed initially, YouTube does plan to add the ability to add different subscription tiers. For example, for $1 monthly, fans might be able to get a membership badge next to their name. For, say, $20 per month, a YouTuber might provide even more exclusive features — like private livestreams.YouTube also touted early results from Channel Membership trials. Travel vloggers Simon and Martina signed up 1,000 paying fans in 30 countries in six days for their members-only miniseries. Comedy creator Mike Falzone launched his sponsor program in January, and has more than tripled his YouTube revenue, according to YouTube, while musician Wintergatan now makes over 50% of his YouTube revenue from Channel Memberships (and plans to use the extra income toward funding a world tour).For the new merchandising option, YouTube has partnered with San Francisco-based Teespring, to let YouTubers design, create and sell about 20 different products. Those products can be featured on a “shelf” underneath videos. Initially, the ecommerce program will be available only the U.S. creators with 10,000 or more followers.Creators set the prices for the items they produce; Teespring keeps a portion of the revenue in addition to production and shipping costs, while Google takes “a small amount” of each transaction, Dhawan said. YouTube is unboxing new ways for creators to rake in more cash, and it’s adding a new way to turn video premieres into anticipatory appointment-viewing events.First is paid Channel Memberships, letting YouTubers offer access to exclusive content, members-only emoji and badges, and other perks for $4.99 monthly. It’s an expanded version of the “sponsorship” program it adopted last fall, after ending its fairly unpopular channel-subscription plan (which basically put an entire channel behind a paywall).The Google video platform also is rolling out a merchandising feature, giving creators a way to sell T-shirts, phone cases, stickers, mugs and other products directly from their YouTube channels. And it’s launching YouTube Premieres, a tool for promoting live and on-demand videos at a scheduled day and time — complete with a countdown timer. YouTube plans to work with other merch companies in the future. It selected Teespring as the launch partner because “they gave us the broadest reach among creators and had the ability to scale,” according to Dhawan, while Teespring also extended better revenue-sharing terms to YouTuber creators through the program than Teespring’s standard deal.Another new feature is YouTube Premieres, aimed at driving up engagement by turning videos into TV-like scheduled events. YouTube already allows on-demand videos to be pre-scheduled. What’s different with Premieres is that YouTube automatically creates a public landing page, which creators can then use to promote an upcoming live or recorded video release.“It’s YouTube’s take on appointment viewing,” said Kurt Wilms, YouTube’s lead for live video and Premieres. “It’s the single biggest change to the upload flow since YouTube’s inception.”Creators who are releasing YouTube Premieres post-VidCon are set to include: Simon & Martina , Leroy Sanchez, Jackson Bird, Los Polinesios, Ari Fitz, ZerkaaPlays, Theskorpionshow, Laura Kampf, Vintage Space, Yammy, R.LUM.R., JacksFilms, Corridor Digital.Premieres also will be really useful to entertainment and media companies, Wilms expects. For example, a movie trailer can be scheduled with a premiere date and time, and studios can promote the URL of the landing page leading up to the reveal.The minute someone schedules a Premiere, the page will be live, with a countdown timer in the lower left-hand corner over the video’s thumbnail image. At the scheduled premiere time, YouTube will kick off a standard two-minute countdown video.The Premieres feature unlocks new forms of monetization, too. The Super Chat paid-messaging features, which has been available only on live streams, is now available in prerecorded VOD. (Creators can choose whether or not to leave up the replay of the chat in the post-Premieres debut version of the video.) In addition, Channel Memberships perks (including members-only live chat and emoji) are now available in VOD via YouTube Premieres. For now, however, there’s no way to restrict access to Premieres videos to paying Channel Memberships users. YouTube is considering adding that down the road, Wilms said.— Ricardo Lopez contributed to this report. Neal Mohan, YouTube chief product officer, unveiled the new features Thursday at Vidcon 2018, the Viacom-owned confab for digital creators and their fans.“We’re working on new ways to help creators strengthen those bonds,” Mohan told a packed ballroom at the Anaheim Convention Center. “That’s why we’ve been working alongside them… Together we’ve experienced the biggest music, sports, science, culture and gaming events unfold live on YouTube in the last year.”Mohan said live-streaming of events like the British royal wedding last month and the launch of the SpaceX rocket attracted millions of people. The new YouTube Premieres feature for creators, Mohan said, is expected to create more real-time interaction between viewers and creators. “It’ll be like the entire audience around the globe for that video will be together,” he said.The goal with the initiatives? As YouTube faces intensifying competition from Facebook, Instagram and others, Google wants to help career YouTubers build bigger fanbases and make more money from their channels.“A lot of creators already are selling merchandise, doing influencer marketing, and fan-funding. We saw these things already happening,” said Rohit Dhawan, alternative monetization lead at YouTube. “So we’re going after the lowest-hanging fruit to make it much easier for them to do it on YouTube.”The results in some of YouTube’s early tests have been huge. For example, Joshua Slice of Lucas the Spider three weeks ago began selling a plushie of his popular animated arachnid (pictured above) — and moved more than 60,000 stuffed spiders in 18 days, netting him over $1 million in profit.According to YouTube, the number of creators earning $10,000 or more annually is up 35% year-over-year and those bringing in at least $100,000 annually is up by 40%. (It doesn’t reveal actual numbers.)YouTube creators have long had the ability to generate revenue through ad-revenue sharing, and a “tip jar” for followers to buy premium chat messages during live-streams.Now it’s letting YouTubers cater to their biggest fans with Channel Memberships, which it has been testing with a few creators in the past few months. Under the program, subscribers pay a monthly recurring fee of $4.99 (currently, the price point can’t be altered) to get unique badges, new emoji, members-only posts in the Community tab and access to unique custom perks offered by creators, such as exclusive live streams, extra videos, or shoutouts. ×Actors Reveal Their Favorite Disney PrincessesSeveral actors, like Daisy Ridley, Awkwafina, Jeff Goldblum and Gina Rodriguez, reveal their favorite Disney princesses.
