HALIFAX – Nearly two-thirds of Nova Scotians seeking assisted suicide in the first six months of 2017 did not receive a lethal injection, with doctors saying the province’s system is short of available physicians and payments are low.The Nova Scotia Health Authority reports that of 64 referrals made for medical assistance in dying, 23 were completed between Jan. 1 and Canada Day.The remaining patients either dropped the request, lost the mental ability to agree — a requirement under Canada’s Bill C-14 — or died before anyone could carry out the euthanasia.Over the past year Bill C-14 has allowed for the procedure when patients are over 18, have a serious and incurable illness or disability, are in an advanced state of irreversible decline, endure intolerable pain, and face a “reasonably foreseeable” death.Dr. Tim Holland — a Halifax doctor who performs medically assisted deaths — said the province’s system needs better ways to train physicians for euthanasia, improved administration and higher reimbursement for doctors.“We have a small set of providers, but we can’t possibly keep up with the patient demand,” he told delegates at the International Conference on End of Life Law, Ethics, Policy and Practice in Halifax earlier this month.He said 20 doctors came to a recent training session, but many also want to witness a procedure first hand — a step that is taking more time than expected to arrange.“We’re two years behind the mark of where we should have been compared to other jurisdictions,” Holland said during a presentation on the early days of medically assisted dying in the province.He also said he has been advocating for the ability to bill for more than four hours, as the process often requires more time than that.“None of us want to make money off of it. But we’d like to see a situation where we’re not losing money in it,” said Holland.A spokeswoman for the Health Department said Friday the fees are still being reviewed, and policies for medical assistance in death are still under development.Cancer was the most common reported underlying condition for the euthanasia, followed by neuro-degenerative, cardiovascular and respiratory diseases, according to the health authority’s records.Since it became available in Nova Scotia in June 2016, 46 people have received medical assistance in dying, the health authority says.Dr. Lynne Harrigan, the vice-president of medicine at the Nova Scotia Health Authority, said there is a “learning curve for everybody involved.”She said in some cases, gravely ill people are applying too late and lose the capacity to consent.In other instances, there is difficulty finding an available doctor, she added.“We’re working to train physicians to come forward,” she said.The law requires agreement between two physicians who are examining the request, and families need to have the process carefully explained, he added.The process also involves a 10-day wait period after a consent form is signed as a time for sober second thought and families to make last preparations. It can be waived if the person is at risk of losing their capacity to agree to their death.Under Canadian law, the person must have the capacity to understand what is occurring up until the point the fatal drug is provided.Another Nova Scotia physician, Dr. Robyn MacQuarrie, said during the euthanasia conference that doctors in the province involved in assisted suicide over the past year already have multiple practices and responsibilities, and most live in a 100-kilometre radius of Halifax — meaning long journeys around the province.Some patients are waiting until the “very end” to request the process, and that is putting pressure on the small pool of doctors involved, she added.“We feel guilt we can’t provide the service right away. Obviously we care about these patients and people having the kind of death they want to have. It’s a bit emotionally overwhelming for us to constantly have these emergency assessments.”Follow (at)mtuttoncporg on Twitter.
Spain’s Diego Costa believes that their 6-1 victory over Argentina could have been a different story had Lionel Messi featured in the matchThe Atletico Madrid forward opened the scoring at the Estadio Wanda Metropolitano for Spain, before having to come off the field injured.Quiz: How much do you know about David Villa? Boro Tanchev – September 14, 2019 Time to test your knowledge about Spanish legendary forward David Villa.But despite their convincing win, Costa felt that the absence of Messi had made a difference to the Argentina side and felt that it had ultimately compromised them.“You have to do an analysis in all aspects, you in Argentina criticize Messi a lot but you can tell that when Messi It is not something else, a player like Messi is not criticized, we have to thank God that he is in. Messi must always be treated well, even if he plays a bad game with the national team, having him in the field is different ” said Costa, according to Marca. The Brazilian native was ecstatic with the final result and is confident that Spain can potentially repeat their 2010 World Cup success this summer.“This team wants to do something big again, there is a good team for the World Cup, I had a bad time because I was not playing for six months but I knew that when I came back I could do it well and be in the selection makes me very excited. ” said the 29 year-old. Costa also reserved special praise for Isco: “Today we have seen, Isco would play on any team.” Argentina was very inferior to Spain: “We played a great match against a great team, Messi was missing”.
Jürgen Klopp decided not to use three of his key players in the Merseyside derby as Mohamed Salah, Andrew Robertson and Roberto Firmino were not included into the starting eleven and the coach explained why.After the starting eleven had been revealed, the Liverpool fans started to worry about the fitness of their team’s crucial players but Jürgen Klopp insisted that he expects them all to be back for the match against City.The German coach spoke about the absence of this trio as he said that all of them will be available for the next game against Manchester City, according to Talk Sport:Report: Origi cause Klopp injury concerns George Patchias – September 14, 2019 Divock Origi injury in today’s game against Newcastle is a cause for concern for Jurgen Klopp.Perhaps with one eye on Tuesday’s trip to Italy…“Mo, he’s injured. I don’t think it is really serious and he can be available for Tuesday but for today he wasn’t available.“It’s the same with Andy Robertson.“Bobby’s out, he’s played a lot of games for us obviously and we have two fresh strikers there.”
The agent of Jorginho insists that his client is enjoying his Chelsea “adventure” and is surprised by the club’s Neapolitan fanbaseThe Italian midfielder has settled in well at Stamford Bridge and has proved to be a valuable alley for his new teammates as they adapt to new manager Maurizio Sarri’s playing style.And his agent, Joao Santos, feels that the move to Chelsea has been a success so far.“Jorginho has started his adventure at Chelsea very well,” he told Radio CRC, via Football-Italia.“He’s already integrated himself, plus he also speaks English well, so he’s not having any problems settling.Chelsea hat-trick hero Tammy Abraham hopes for more Andrew Smyth – September 14, 2019 Tammy Abraham hopes this season will be his big breakthrough at Chelsea after firing his first hat-trick for the club in Saturday’s 5-2 win at Wolves.“When a player is good, he can play in any League. Stereotypes matter little. If a player has quality, they can make the grade anywhere.”Santos also revealed that 50 Neapolitans greeted Jorginho at the end of Chelsea’s 3-2 win over Arsenal in Saturday’s London derby.“He’s very happy with how the match against Arsenal went. There were 50 Neapolitans who cheered him on and asked for photos and autographs,” he said.“This is why we love Naples and we’ll continue to. Their support has continued in London. Jorginho has many friends in Naples, like Mertens and Insigne.“He heard from them after Napoli’s win against Lazio and complimented the team.”
Rangers defender Connor Goldson insists the team must improve their performances if they’re to defeat Hibernian.The former Brighton & Hove Albion says there can be no repeat of the team’s first-half display against St Johnstone if they’re to secure all three points on Boxing Day at the Ibrox Stadium.Steven Gerrard’s men struggled in the opening 45 minutes of the game against St. Johnstone and found themselves trailing before a brace from Alfredo Morelos turned the game on its head.It’s the second game between the two teams in the space of seven days following the goalless draw at Easter Road on Wednesday, and Goldson explained, according to the club’s official website: Rangers is still behind Celtic: John Hartson Manuel R. Medina – September 3, 2019 According to the former Celtic player, there’s still a massive gap between his ex-club and Rangers in the Scottish Premier League.“They are a good side, and we showed them respect going there by the way we set up and we had a game plan of playing on the counter attack.”“I think it worked really well but we missed quite a few chances which was a bit frustrating as we had a good chance of winning the game.”“But, at the same time, we know they are dangerous, they can hurt us and they have good players. We know we are going to have to be at it and we can’t put in a performance like the first half yesterday.”“But if we put in a performance like the second, we will have a good chance of getting the result we want.”
Arsenal goalkeeper Petr Cech says the club’s big objective in the Premier League this season is to get into the top four.After their 3-0 FA Cup win at Blackpool on Saturday evening, Cech outlined their targets and objectives for the season.Arsenal are in 5th place and trailing fourth-placed Chelsea by three points, but a resurgent Manchester United side is breathing down their necks with just three points separating them.“Personally I love the competition,” Cech told the club’s website.“I haven’t played it much in my career but most of the time I played at the end and I have five [winners’ medals].“I am very proud of them because it is a great competition to win and something to remember and something to look at one day when you retire.“The FA Cup final is a special occasion for any player playing in England.Premier League Betting: Match-day 5 Stuart Heath – September 14, 2019 Going into the Premier League’s match-day five with a gap already beginning to form at the top of the league. We will take a…“Our priority is to get into the top four [so we can] be in the Champions League and then you want to progress and evolve as a club, as a team.“We have a new manager and obviously we set our targets so if we can win a trophy together in the first season it would be a good achievement.“You play every game to win and this time we were in the FA Cup, we have the tradition as a club to do well and if we can win it, we’d like to do so.“It is the same with the Europa League – we started really well and are in the last 32.“These are two targets but the Premier League remains a big objective, to get into the top four.”
Dye-sensitized solar cells with carbon nanotube transparent electrodes offer significant cost savings Copyright 2012 Phys.org All rights reserved.

Lee, et al. “Efficient Hybrid Solar Cells Based on Meso-Superstructured Organometal Halide Perovskites.” Science Express. DOI: 10.1126/science.1228604 , Science Express (Phys.org)—It may sound counterintuitive that replacing one of the most photosensitive solar cell materials with a material with less desirable photosensitive properties can improve the solar cell’s efficiency, but that’s what scientists have shown in a new study. By replacing the highly photosensitive titanium dioxide (TiO2) with alumina (Al2O3) in a solution-processable solar cell, the researchers have achieved a record power conversion efficiency of 10.9%. They attribute this high efficiency to the Al2O3 acting as an inert scaffold, forcing the electrons to remain within and be transported through an extremely thin absorber (ETA) layer. The researchers, led by Henry J. Snaith at the University of Oxford in the UK, with coauthors from the University of Oxford, Toin University of Yokohama in Japan, and the National Institute of Advanced Industrial Science and Technology in Ibaraki, Japan, have published their study on the highly efficient solar cells in a recent issue of Science.”This is a new technology, so in essence a new record,” Snaith told Phys.org. “All solar cell technologies have different efficiencies, with GaAs being the highest at over 28%. This is not an absolute world record, but probably the highest for a solution-processable solid-state solar cell. And the real excitement is where it may reach over the next few years; it should have a steep improvement curve.”The choice of electrode material in a solar cell is one of the most important factors contributing to solar cell efficiency, and TiO2 is often used as an electrode material in solution-processable solar cells due to its good ability for photoexcitation, or converting photons into electrons, as well as its strong electron-accepting properties when photosensitized with a dye or absorber. But in order to improve solar cell efficiency, the scientists here addressed the fundamental energy losses that arise throughout the photovoltaic process of absorbing photons and generating electrons. As they explain, energy is lost during the photogeneration of electron-hole pairs (excitons), the separation of tightly bound excitons, and the extraction of free electrons from highly disordered networks. In attempts to overcome these losses, previous research has investigated the use of coating an ETA layer, 2 to 10 nm in thickness, on the internal surface of the TiO2 electrode in order to increase the current density and voltage. So far, solar cells with ETA layers have achieved power conversion efficiencies of up to 6.3%.Here, the researchers have investigated the possibility that TiO2 may be hindering the effectiveness of the ETA layer due to its electronic disorder and low mobility. Because Al2O3 is a wide band gap insulator, the researchers found that, when it’s used as the electrode, the photoexcited electrons remain in the ETA layer and do not drop to lower energy levels in the oxide as they do in the TiO2 electrode. This difference offers several advantages. For instance, the researchers found that using Al2O3 significantly speeds up the electron transport process, forcing electrons to quickly travel through a perovskite ETA layer, and also increases the voltage. These improvements increased the power conversion efficiency from 8% with the TiO2 electrode to 10.9% with the Al2O3 electrode. Because the Al2O3 is mainly acting as a meso-scale scaffold, and does not play a role in photoexcitation, the researchers call this device a “meso-superstructured solar cell” (MSSC). “The alumina is acting as a scaffold for the perovskite layer, and subsequently the hole-conductor which is coated on top of the perovskite layer,” Snaith said. “It is not electronically active, but purely acting as a physical support.”It is very surprising and would not have been predicted,” he added. “However, in hindsight we can see where the efficiency gains come from. The real surprise is that the perovskite layer is so effective at transporting charge and generating high photovoltage in the solar cell.”The scientists expect that the efficiency can be further improved in the future by various means, such as experimenting with new perovskites, using other semiconductors, and extending the absorption range.”This work moves low-cost solution-processable solar cells significantly closer to the performance of perfectly crystalline semiconductors, while at the same time opening extensive possibilities for future research and development,” Snaith said.
