Sarri hints at squad rotation

first_imgChelsea manager Maurizio Sarri has hinted at rotating his squad ahead of a busy run of matched both in the league and in Europe.The former Napoli manager, who has used the second least number of players this season, has revealed that he will possibly call on some of the club’s fringe players with the match roster about to get packed.“We have used 26 players in official matches [in all competitions] this season so the rotation at the moment is this, but I don’t know in the future,” said Sarri, according to LiveSoccer.Maurizio Sarri, JuventusMaurizio Sarri satisfied despite Juventus’ draw at Fiorentina Andrew Smyth – September 14, 2019 Maurizio Sarri was satisfied with Juventus’ performance on Saturday afternoon after finishing a tough game at Fiorentina 0-0.“If you look only in the Premier League the situation is that, you are right [only used 19 players] but I have to look at all competitions: 90 minutes are 90 minutes. You have to look at the League Cup, Europa League, and the national team.“I have to look also to the minutes in the national teams. So I think the rotation is good. Every moment was done only between the Europa League, League Cup, and Premier League but, in the future, it will be different.“If you look at December and January, you need to change also in the Premier League because we will play every three days in the Premier League. So we need to change in the Premier League.”last_img read more

There will also be a bike lane and pride plaza expansion, with 60 additional parking spaces, full-time security, and a special events program.They say adding these features will give eastern Hillcrest the first transit-oriented pedestrian promenade in San Diego.After waiting hours Tuesday night to find out the results, residents were overjoyed their fight finally coming to fruition.

Googles pricey Pixel phones arent selling even at steep discounts

first_img Comments Preview • Pixel and Pixel XL unveiled: Google’s post-Nexus phones come out swinging (hands-on) Tags Mentioned Above Google Pixel (32GB, Quite Black) 5:52 Pixel 3: 6 months in 15 Pixel 3 features you should use right now See it How To • How to transfer your data from an iPhone to Android phone Phones Rumors Google The company has become more aggressive in trying to get more people to switch to its phones, with a new promotion on the Google Play Store knocking the prices down by $200, bringing the regular Pixel 3 to a $599 starting price and the 3 XL to $699.  Earlier this month the company went so far as to take 50% off the Pixel 3 price if purchased on Google Fi, though that deal has since ended.  Luckily for the company, and fans of the brand hoping to save a bit more, rumors point to the Pixel 3 getting cheaper siblings shortly. Dubbed the Pixel 3a or Pixel Lite, the new phone is expected to share the same general look as the current Pixel line, but switch to a slower Snapdragon 670 processor, lower standard storage (32GB instead of 64GB) and plastic as opposed to glass, to get to a cheaper price.  Noted leaker Evan Blass recently tweeted images of the forthcoming handset, including one in a new purple hue.  News • Google Pixel 3A: Where is AT&T?

Porat said that Pixel sales were lower year over year, in part due to “heavy promotional activity industry-wide, given some of the recent pressures in the premium smartphone market.” Google’s latest Pixels, available from Verizon, Google’s Fi or unlocked in the US, launched last October starting at $799 for the 5.5-inch Pixel 3 and $899 for the 6.3-inch Pixel 3 XL. The high prices put the phones in close competition to rival flagship devices from Apple and Samsung.  17 Photos CNET may get a commission from retail offers.last_img read more

Hydrogen fuel cells provide power when fuel supply is off

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. (Phys.org) — Fuel cells, which generate electricity from the chemical energy of a fuel such as hydrogen, are not intrinsically capable of storing energy. When a fuel cell’s hydrogen supply runs out or is temporarily interrupted, the cell’s power output quickly decreases to zero. If an application requires energy storage, then the fuel cell must be coupled to an external charge storage device, such as a battery, which increases the weight and volume of the system. But now researchers have designed a hydrogen fuel cell with a new anode that can supply electricity up to 14 times longer than conventional fuel cells, which could be particularly useful for mobile energy applications.

Image credit: Quentin Van Overmeerecenter_img For now, the researchers do not know exactly what allows the new fuel cell to run after its supply is cut off. They identified and tested three possible charge storage mechanisms, with the results showing that reversible oxidation of the anode contributed a portion of the observed charge, but did not account for all of it. The finding suggests that the power generation in the absence of fuel arises from multiple mechanisms.Although identifying the underlying mechanisms will require further research, the discovery that vanadium oxide anodes can store energy and deliver power when the fuel supply is depleted could be useful for developing future miniature power sources. Applications could include miniature autonomous systems, military technologies, and other devices that need to operate for short time periods.”Unmanned aerial vehicles, for instance, would really benefit from this,” said Van Overmeere. “When it’s impossible to refuel in the field, an extra boost of stored energy could extend the device’s lifespan significantly.” More information: Quentin Van Overmeere, Kian Kerman, and Shriram Ramanathan. “Energy Storage in Ultrathin Solid Oxide Fuel Cells.” Nano Letters.

Vanadium is known for its tendency to change oxidation state, a process that involves the transfer of electrons. Since a key to enabling fuel cells to store charge is to use materials that can reversibly transfer electric charges, vanadium’s properties make it a good candidate for these technologies. “This thin-film SOFC takes advantage of recent advances in low-temperature operation to incorporate a new and more versatile material,” said Ramanathan. “Vanadium oxide at the anode behaves as a multifunctional material, allowing the fuel cell to both generate and store energy.”The researchers’ experiments showed that, after the hydrogen fuel supply is turned off, fuel cells with the vanadium oxide anode could generate power for more than 3 minutes, compared with about 10-15 seconds for fuel cells with porous platinum anodes. Both fuel cells produced a comparable amount of power, and the researchers expect that future improvements will further extend this time. With the ability to store electrochemical energy, the new device could be thought of as combining the characteristics of a fuel cell and a battery.last_img read more

Stop Posting Your Childs Tantrum on Instagram

first_imgNaturally, joking serves a purpose — it provides psychological distance from negative feelings like shame or anxiety. A study of 105 wheelchair-bound college students found that humor, especially concerning bladder and bowel problems, was a key method of coping with distress. As one respondent said, “We have to laugh at ourselves to make life easier.” Read the whole story: The New York Times Publicly laughing at your toddler’s distress has somehow become not only acceptable but encouraged. Websites offer “best of”compilations, or canned quips readers can use when posting tantrum photos and videos (“Metallica has a new lead singer”). As psychologists and parents ourselves, we understand the urge to laugh when a child howls because he’s forbidden to eat the packing peanuts from the Amazon box, and we also understand the impulse to make these moments public. The problem is the mockery.center_img What should a parent do when a 2-year-old shrieks inconsolably because her string cheese wrapper tore “the wrong way”? Increasingly, the answer is “snap a photo, add a snarky caption and upload it to Instagram.”last_img read more
