Heart rate and behaviour of fur seals: implications for measurement of field energetics

first_imgArchival data loggers were used to collect information about depth, swimming speed, and heart rate in 23 free-ranging antarctic fur seals. Deployments averaged 9.6 ± 5.6 days (SD) and totaled 191 days of recording. Heart rate averaged 108.7 ± 17.7 beats/min (SD) but varied from 83 to 145 beats/min among animals. Morphometrics explained most variations in heart rate among animals. These interacted with diving activity and swimming speed to produce a complex relationship between heart rate and activity patterns. Heart rate was also correlated with behavior over time lags of several hours. There was significant (P < 0.05) variation among animals in the degree of diving bradycardia. On average, heart rate declined from 100–130 beats/min before the dive to 70–100 beats/min during submersion. On the basis of the relationship between heart rate and rate of oxygen consumption, the overall metabolic rate was 5.46 ± 1.61 W/kg (SD). Energy expenditure appears to be allocated to different activities within the metabolic scope of individual animals. This highlights the possibility that some activities can be mutually exclusive of one another.last_img read more


Harry Kane at the double as Tottenham brush aside West Ham

first_img With West Ham unquestionably beaten, Walker’s goal, from inside the area in the 83rd minute, resembled one more likely to be seen in training. Casually exchanging a one-two with Son that began outside the penalty box, the full-back masterfully bent the ball with the outside of his right foot into the bottom corner. Equally casually, he then gave Lanzini possession four minutes later in defence, allowing the midfielder to run into the area and beat Hugo Lloris by finishing high inside the near left post. Conceding will understandably have frustrated Pochettino, but while much has been said about his team’s promise so far this season, on this evidence there remains more to come. TWEET OF THE MATCH Gary Lineker ‏@GaryLineker This is the most promising Spurs outfit for many a year. Pochettino has got them bang on! https://twitter.com/GaryLineker/status/668481510622797824 PLAYER RATINGS Tottenham Hugo Lloris: 6 (out of 10) Kyle Walker: 7 Toby Alderweireld: 8 Jan Vertonghen: 7 Danny Rose: 7 Eric Dier: 7 Dele Alli: 6 Mousa Dembele: 8 Christian Eriksen: 7 Son Heung-min: 7 Harry Kane: 8 Subs Ryan Mason (for Alli, 71): 6 Josh Onomah (for Son, 86): 5 Tom Carroll (for Kane, 91) 5 West Ham Adrian: 7 Carl Jenkinson: 4 Winston Reid: 5 James Tomkins: 4 Aaron Cresswell: 4 Mark Noble: 5 Cheikhou Kouyate: 6 Diafra Sakho: 5 Manuel Lanzini: 7 Victor Moses: 6 Andy Carroll: 6 Subs Nikica Jelavic(for Moses, 63): 5 Mauro Zarate (for Carroll, 63): 6 Alex Song (for Noble, 80): 5 STAR PLAYER Harry Kane: His double means it is now eight goals in five games for the Tottenham striker, who could have had a hat-trick had he slotted a one-on-one in the first half. Undeterred, Kane managed another rousing display and looks firmly back to his best. MOMENT OF THE MATCH La Marseillaise played out around White Hart Lane before kick-off in tribute to the victims of the Paris terrorist attacks and there was a moving show of support from the Spurs fans towards their goalkeeper and France captain Hugo Lloris. Lloris received a standing ovation from the home fans behind the goal and at full-time,expressed his gratitude by clapping all sides of the ground. VIEW FROM THE BENCH Mauricio Pochettino will be delighted with another confident display from his side and he was even afforded the luxury of resting Alli, Kane and Son in the second half, with a six-hour trip to Qarabag to come in the Europa League on Thursday. Slaven Bilic’s men looked a pale shadow of the disciplined team that beat Arsenal, Liverpool and Manchester City earlier this season. MOAN OF THE MATCH Dele Alli has enjoyed a brilliant start to the season but the 19-year-old was less influential playing further forward behind Kane. With Tottenham 3-0 up, he picked up a needless booking for an altercation with Mark Noble and will now miss Tottenham’s game against Chelsea next Sunday. WHO’S UP NEXT Qarabag v Tottenham (Europa League, Thursday, 26 November) West Ham v West Brom (Premier League, Sunday, 29 November) Man of the match Kane said on Sky Sports: “I enjoy the atmosphere of these games, especially when we’re at home. The crowd were incredible, they got right behind us, and we put in a good performance.” Tottenham have lost just once in this Premier League campaign, but Eric Dier tempered expectations. “We’re going game by game, we’re not going to get excited,” he said. “We’re going to keep doing what we’ve been doing since the beginning of the season. If you ask any Spurs player, that’s what they’d tell you. We’ll keep on trying to perform as we’ve been doing, work hard, and we know that if we perform like we did today then we’re going to get wins and push right at the top, so we just need to do that.” Pochettino, the Spurs boss, saluted his team’s display. “It was a high level of performance. It was fantastic, I’m very proud of the players,” he said. “The way we played today, we showed how we can play, and we need to perform like that all season. “I never had a doubt about Harry Kane. It’s difficult sometimes to score in every game but Harry is top. We have a very good squad, I’m very happy in the way we work every day.” They consistently outplayed their visitors as two goals from Harry Kane and one each from Toby Alderweireld and Kyle Walker took them within two points of joint-third-placed Arsenal and Manchester City and three ahead of sixth-placed West Ham, whose goal came from Manuel Lanzini. Son Hueng-min returned to Tottenham’s starting XI in the absence of the suspended Erik Lamela, while West Ham, for the coming three months without the injured and important Dmitri Payet, started with Andy Carroll, Victor Moses and Diafra Sakho. Following his outstanding recent goal for England against France, much of the early attention inevitably centred on Dele Alli and the midfielder – curiously switching with Mousa Dembele from his usually-deeper position to No 10 – was central to Spurs’ opening goal. Receiving possession from Son in the 23rd minute, Alli found room to shoot from inside the area but watched as Winston Reid deflected the ball to Kane, who in one motion classily turned Carl Jenkinson before shooting with his left foot beyond goalkeeper Adrian into the roof of the net. It could easily have already been more. With West Ham defending from a deep position amid Spurs’ intensity, Christian Eriksen had previously tested Adrian with a powerful strike from midfield and the visitors’ Cheikhou Kouyate, albeit from an offside position that went unnoticed, had hit the crossbar with a bicycle kick. The momentum theirs, Spurs continued to threaten and within 10 minutes had doubled their lead. From a corner on the left, Eriksen delivered a typically-accurate, inswinging cross which Alderweireld read to routinely head in from close range. Kane soon should have scored a third when one-on-one with Adrian after Alli’s through-ball, but despite time and space the forward showed an uncharacteristic lack of composure to shoot with his weaker left foot and miss the target by considerable distance. Had he done so, it would have been difficult to see any way West Ham could have recovered from such a half-time deficit. It said much about the inaccuracy of suggestions that they can compete with Spurs for a place in the top four when they were so visibly an inferior team. The only chance they had came in scoring the second half’s first goal, and ideally soon after the restart, but Mauricio Pochettino’s Spurs are a more ruthless team than has been seen under his predecessors, and they instead swiftly sealed victory. Maintaining their aggressive, high-paced football, they immediately attacked and then took advantage when James Tomkins thoughtlessly conceded possession with a misplaced pass to Eriksen. With West Ham’s defence out of position, the midfielder played in Kane, and he atoned for his earlier error by shooting past the exposed Adrian into the bottom left corner to score his eighth goal in his past five Spurs games. Tottenham demonstrated their Champions League credentials with a convincing 4-1 Premier League home defeat of West Ham that exposed their London rivals as pretenders at that level.

Energy Code Development Begins: Commercial Proposals

first_imgThis article is the second of a two-part series. To read about residential code proposals, click here.With millions of commercial and apartment buildings in the United States, an improved model building energy code can make a significant difference when it comes to reducing energy waste, saving owners and tenants money on their utility bills, and avoiding power plant pollution. Updating the code also is a critical policy tool for states, counties, and cities working to stave off the worst impacts of the climate crisis.That’s why code officials, builders, energy efficiency advocates, and others met last month in Albuquerque on proposals to update the next model residential and commercial building codes for homes and the commercial energy code. In Part One of this series, I discussed the proposals at play for the residential energy code. Today we’re examining the commercial energy code, which covers building elements like insulation, windows, and mechanical equipment in non-residential buildings and multifamily structures over four stories in height.The processAs part of the process of updating the energy code, the Natural Resources Defense Council and many others submitted proposals to the International Code Council back in January, offering a variety of ideas for modifying the energy code.The Committee Action Hearings in May gave proponents and opponents of each proposal the opportunity to hash it out in front of a technical advisory committee, which then voted on each one. Next, proponents can revise and resubmit proposals, which will be discussed again during the Public Comment Hearings in October. Governmental voting members like city code officials or sustainability directors have the final word, and they’ll get to vote on each proposal in November.While governmental officials hold the ultimate power on what goes into the new building energy code, the commercial code committee’s action this month is still important: a favorable recommendation means a proposal only needs a simple majority of governmental official votes to pass and become part of the code, while a committee recommendation for disapproval means that a proposal requires a two-thirds majority of votes to reverse it to become part of the code.Commercial proposalsWe’ve previously noted how difficult it is to get good energy efficiency proposals passed by the notably challenging residential code committee. Well, I’m happy to report that the commercial committee was much more favorable to energy efficiency, and if all goes well in the November vote, there will be substantial energy efficiency improvements in the commercial energy code.Electric vehicle chargingA proposal for electric vehicle charging infrastructure (CE217 Part 1) received a favorable recommendation from the committee, which is great news. While promoting electric vehicles may initially seem like a completely separate issue from the building energy code, where do you charge your electric car? Generally at the building where you live or work. And it’s much cheaper and easier to install the charging infrastructure, which includes conduit and wiring and space on the electric panel, at the time of construction.Electric vehicles are key to the fight against the climate crisis. More than 95% of the energy used in transportation comes from oil, which means high levels of pollution and emissions. Electric vehicles have much lower emissions, and every major automaker plans to electrify a significant portion of its vehicle fleets in the coming years.However, a key barrier to customer adoption is the lack of access to EV charging stations. This proposal would require a certain percentage of parking spaces in commercial buildings to be ready to support electric vehicle charging infrastructure, which makes sense for drivers, building owners, and the Earth.InsulationThe committee also passed a swath of proposals that will improve the insulation required in roofs (CE61), above- and below-grade walls (CE63 and CE64, respectively), floors (CE66) and building slabs (CE68 and CE69). Each of these proposals would have a moderate impact on a building’s energy efficiency, but taken together they will result in buildings that use less energy and are more comfortable.Furthermore,  these proposals make improvements based on extensive research and cost-benefit analyses used to support ASHRAE 90.1, which is another type of building energy standard commonly used for commercial building construction. By selecting the most efficient, cost-effective requirements from the IECC and ASHRAE 90.1, these improvements will help ensure that commercial buildings reap the benefits of efficiency. And since insulation is likely to remain unchanged over the useful life of the building (70-100 years or more), these improvements will benefit generations of building occupants.Plug loadsMiscellaneous electrical loads – meaning all the things you plug in, like monitors, printers, and space heaters – use more than one-third of the energy in the average commercial building. That number is projected to grow to nearly 45% over the next 15 years. Lots of energy is wasted by printers or monitors that consume energy in idle mode, even when nobody is there to use them. A proposal passed the committee (CE216) that will require at least half of all electrical outlets to have automatic shutoffs, to cut down on this “vampire load.”FenestrationWhen it comes to fenestration (meaning any openings in the building’s envelope, like windows or doors), there were multiple proposals (CE84 and CE87) that will significantly increase efficiency. A broad range of representatives in the fenestration industry reached a consensus that will both improve the efficiency and comfort of windows, and also align the IECC and ASHRAE 90.1, making compliance and enforcement easier.That’s great news for anyone in an office building or a high-rise multifamily building who sits near a window that is too hot in the summer: improved fenestration saves energy while making buildings more comfortable and reducing solar heat gain.…And more!My colleagues Dan Bresette at the Alliance to Save Energy and Kim Cheslak at the Institute for Market Transformation give a great overview of some additional proposals that passed the commercial committee, including proposals that would require energy-monitoring systems (CE215), improve the efficiency of ventilation in multifamily buildings by requiring energy recovery ventilation systems, and making changes to the structure of the code to make it clearer and easier to use (CE41, CE42 Part 1, and CE218, among others).There’s also an interesting proposal (CE264) to codify Architecture 2030’s ZERO CODE as an option for code compliance. And just like in the residential code, efficiency advocates were successful at ensuring that the commercial code doesn’t slide backward, in spite of numerous attempts to weaken it by some attending the committee hearing.It was a great few weeks in Albuquerque, and we’re off to a solid start to make the 2021 energy code the best one yet.Lauren Urbanek is senior energy policy advocate at the NRDC’s Climate & Clean Energy Program.
