The Rockets Are Finally Playing Their Game In The Playoffs

It’s unlikely that the Rockets will play the rest of the series at the level they played Game 1 — the 27-point loss was the worst of the Spurs’ season. But however the series plays out, it’s progress that the Rockets have finally brought Rockets basketball to the playoffs. The biggest change has been in the number of threes the team gets. Over the previous three seasons, the Rockets led the league in 3-point attempt rate (the share of field-goal attempts that are 3-pointers) during the regular season before seeing significant dropoffs in the postseason. That’s particularly unusual, considering the playoff field as a whole had a higher rate in this span than the leaguewide regular-season rate.This season, the Rockets have seen a similar slide toward the mean. But they began with such an overwhelming cushion that although they’ve gone from 46.2 percent of their attempts being threes during the season to 40.3 being so in the playoffs, that 40.3 number would have led all teams during the regular season.It’s especially promising for the Rockets’ identity that they’ve continued to put up shots even though they haven’t been falling. In the Oklahoma City series, Houston shot 28 percent from three over five games and 169 attempts, including 6-for-37 in the series clincher. This was somewhat because of good coverage — the Thunder held the Rockets to 10 uncontested2No defender within 6 feet. threes per game, five fewer than their regular season average — but mostly it was just a cold spell that seems to have corrected itself. Against the Spurs in Game 1, the Rockets got 14 wide-open threes, right around their season average.Houston’s free-throw rate (a team’s number of free-throw attempts per field-goal attempt) hasn’t seen as consistent a downturn in the playoffs as its 3-pointers, but it’s fluctuated. The team has finished in the top two in each of the last four regular seasons, but the fouls dried up in its 2014 and 2016 playoff campaigns. Through six games this postseason, however, the team is drawing free throws at by far the highest rate in the field. The strangest thing about the Houston Rockets’ 126-99 dismantling of the San Antonio Spurs on Monday night wasn’t the final score, or the Spurs’ bloodless play, or even the 50 3-pointers (and 22 makes) that Houston threw up in the game. Those were all unusual, but in the way that any one-off game in a seven-game series might be. For Rockets fans, however, the big change was that for once in the playoffs, the Rockets looked like the Rockets.Over the last four seasons,1The period for which we have player-tracking data for the league.

Redknapp insists January is a crucial month for Hassenhuttl

first_imgJamie Redknapp insists January is an important month for new Southampton manager Ralph Hassenhuttl if he’s to keep the club in the Premier League.The former Saints midfielder believes Hassenhuttl must spend wisely when the transfer window reopens next month if the club are to avoid relegation.Redknapp said, as quoted by the Daily Echo:“The upcoming transfer window will be the most important for Southampton since their return to the Premier League.”“They have been a selling club in recent seasons, but now new manager Ralph Hasenhuttl must spend wisely to get them out of trouble.”“He should also give Charlie Austin a run in the side. They are in real need of more firepower.”Solskjaer slams Man United’s draw: “We should have won” Andrew Smyth – August 31, 2019 Ole Gunnar Solskjaer was left to rue another missed opportunity as Manchester United were held to a 1-1 draw against 10-man Southampton.“Only Manchester City and Chelsea have had more shots than Southampton, yet they have scored just 13 goals.”Hassenhuttl lost his first game in charge of Southampton to Cardiff but despite the result, Redknapp revealed the Saints players are already impressed by what they’ve seen from the former RB Leipzig boss.He added: “Their rivals are rallying, too. Cardiff — who beat them on Saturday — are starting to pick up points, Burnley got a vital win over Brighton and Huddersfield are improving.”“Southampton players I speak to say they have been impressed by Hasenhuttl since he has arrived, but he will be judged on whether the players he brings in can inspire a turnaround.”last_img read more

Adani to Invest 2 Billion in Odisha Power Plant

first_imgGujarati billionaire Gautam Adani has planned to invest $2 billion for a 2,500 megawatt power plant at Angul district in Odisha State to boost power supply.He who build a power, mining and ports giant with revenue of nearly $9 billion has acquired a power plant from Lanco Infratech last month.”The Adani Group is the largest private power producer in India, which expects to sign a deal with the government of Odisha in next four months to set up a new plant,” Reuters quoted Rajesh Jha who looks after the group’s mining business in the state.The Adani group plans to generate 1,000 megawatts (MW) of electricity within the next three years in Odisha and will source coal from Machhakata and Chhendipada coal block with a total capacity of 70 million tonnes per annum (mtpa).The Chhendipada block has a mining capacity of 40 million tonne per annum (mtpa), which is allocated to the UCM Coal Company, a joint venture promoted by Maharashtra State Power Generation Corporation (MAHENGENCO), Uttar Pradesh Rajya Vidyut Utpadan Development Corporation (UPRVUNL) and Chhattisgarh Mineral Development Corporation (CMDC).On the other hand, the Machhakata Coal block is allocated to MahaGuj Collieries Limited (MGCL), a joint venture of Maharashtra State Power Generations Corporation Limited (Mahagenco) and Gujarat State Electricity Corporation Limited (GSECL), that projects an initial mining capacity of 30 mtpa.”We are looking at couple of sites and the exact location will be finalised within few months. The investment in the project will be close to Rs 12,500 crore,” Business Standard quoted Rajesh Jha.He added that the power plant would require 25 million tonnes of coal per year at full capacity. The land acquisition for the coal blocks by the Odisha Industrial Infrastructure Development Corporation (IDCO) is in progress and Jha hopes that the blocks will be operational within two years.The Adani Group, controlled by Adani Enterprises has 9,240 MW of power capacity at its plants in Gujarat, Maharashtra and Rajasthan. It imports about 100 million tonnes of coal every year, mainly from Indonesia to feed the plants.Currently, Adani Group is implementing coal mining projects with a total annual coal production capacity of around 110 mtpa, that aims to achieve 200 mpta coal mining capacity by 2020.After the Supreme Court declared on Monday that all coal block allocations and licenses issued to mining companies were unlawful since 1993, the stock prices of most power and coal companies dropped.The stocks of Adani Enterprises dipped 1.35 percent and ended at ₹497.65 per share.last_img read more

NRA Rallies Members In Dallas Facing New Pressure And Anger

first_imgMike Stewart/APPresident Trump speaks to the National Rifle Association in 2017 in Atlanta. Despite new political pressure, the president and vice president are both scheduled to speak to the group this year.Tens of thousands of gun owners are gathering in Dallas for the National Rifle Association’s annual convention, as the group’s leadership rallies its rank-and-file in a political climate altered by the school shooting in Parkland, Fla., and the student protests that followed.The aftermath of the mass shooting, which cost 17 lives, makes this an important moment for the NRA. While its leaders remain insistent that more gun control will not stop such carnage, some acknowledge a shift in the way the country is talking about firearms.“Of course [Parkland] increased the probability in some states of legislators passing more meaningless legislation,” Tom King, an NRA board member from New York, tells NPR.“That’s going to happen, it already has happened. But has it eroded the NRA’s position? I don’t think so.”The three-day convention opens Thursday night, with President Trump and Vice President Mike Pence scheduled to be the key speakers on Friday — a sign of the NRA’s resilient power and influence. The convention features a series of forums and speakers on gun and safety issues and a huge exhibition hall with the latest weaponry.A big question in Dallas is how the NRA leadership navigates the less certain climate. Will it find new ways to tell its story to a country shaken by Parkland? Will there be a different conversation among rank-and-file gun owners about firearm safety?Protesters, including student activists, are expected to make their voices heard outside. A large rally in favor of gun control has been organized for Saturday morning at Dallas City Hall.King calls new gun control legislation “meaningless” because he’s convinced it won’t keep people or schools safe. But a growing number of people disagree, including some Republican leaders who have been closely aligned with the NRA.Among them is Florida’s Republican Gov. Rick Scott, who signed bipartisan gun legislation in the aftermath of the Parkland shooting that raised the age for gun purchases, while making it easier for law enforcement to take firearms from persons deemed a public risk. Scott and Florida’s Republican-controlled legislature defied the NRA to pass the measure.“The hardest thing I’ve ever had to do as a governor is try to find the words to console a parent who has lost their child,” Scott said at a signing ceremony in March.Vermont’s Republican Gov. Phil Scott also signed sweeping gun-control measures this spring and New York’s Republican-controlled Senate helped tighten that state’s already-strict gun laws. In all, at least seven states from Oregon to Rhode Island approved new gun legislation since the Parkland shooting, as have some municipalities.“I think that is a really important shift,” says Kris Brown, co-president of the Brady Campaign to Prevent Gun Violence, a group that supports tighter gun laws.She believes the NRA lost ground after Parkland, fumbling control of the conversation, failing to adapt to a new national mood.“When we look at the last year with three of the deadliest mass shootings in American history, the NRA has been tone deaf,” she says.Brown points to surveys that have long shown most gun owners and many NRA members support creating a stronger system of background checks for gun buyers, one that closes loopholes for private sales. But she credits the Parkland students for redefining the gun debate.It was just a year ago that the NRA was so confident in its clout that the group had taken to mocking its political opponents, promising to crush anyone who proposed new gun laws.In a controversial video that went viral, spokeswoman Dana Loesch said the NRA would prevail by using “the clenched fist of truth.”Then came Parkland. In the days after the shooting, a new group of voices emerged in favor of gun control — student survivors who took on the NRA directly.“To every politician who is taking donations from the NRA, shame on you,” said Majorie Stoneman Douglas High School senior Emma Gonzalez at a rally shortly after the shooting. Her words drew a roar of applause and have been looped again and again on TV and social media.Even President Trump, a close NRA ally, publicly challenged the organization — at least for a rare moment.In a White House meeting with members of Congress two weeks after the Parkland shooting, he called for comprehensive new gun legislation and he accused lawmakers of being “afraid” of the NRA.“They do have great power, I agree with that,” Trump said. “They have great power over you people. They have less power over me.”But the NRA quickly flexed its political muscle. After a closed-door meeting with the group’s leaders, Trump backed off and the Republican-controlled Congress hasn’t approved new gun control bills.That fact and the decision by Trump and Pence to attend this week’s convention is a sign that the NRA remains a powerful force. Donations to the organization actually surged after Parkland.As rank-and-file members gather, board member Tom King says the NRA will once again make the case that firearms aren’t the real public safety issue.The focus should be on other things, including more security in schools, King says. “Until we talk about the core issues, getting people jobs, getting the criminals off the streets, stopping the drug trade, we are going to be a dangerous country.”Copyright 2018 NCPR.

Study identifies two biomarkers for lack of sleep

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. © 2015 Phys.org Common biomarkers of sleep debt found in humans, rats, study finds (Phys.org)—Ideally, we would get the appropriate amount of sleep to keep our bodies healthy, but in our modern society things like jet lag, extended work hours, or using electronic devices cause disruptions in our sleep/wake cycle often leading to fewer hours of quality sleep. Most people suffer from chronic sleep restriction rather than complete deprivation, but there are very few studies that explore the effects of sleep restriction. Amita Sahgal and Aalim Weljie from the University of Pennsylvania and Peter Meerlo, from the University of Groningen in The Netherlands, investigated at how chronic sleep restriction affects the body’s metabolic processes. Their work is published in the Proceedings of the National Academy of Sciences. More information: “Oxalic acid and diacylglycerol 36:3 are cross-species markers of sleep debt.” PNAS 2015 ; published ahead of print February 9, 2015www.pnas.org/content/early/2015/02/03/1417432112AbstractSleep is an essential biological process that is thought to have a critical role in metabolic regulation. In humans, reduced sleep duration has been associated with risk for metabolic disorders, including weight gain, diabetes, obesity, and cardiovascular disease. However, our understanding of the molecular mechanisms underlying effects of sleep loss is only in its nascent stages. In this study we used rat and human models to simulate modern-day conditions of restricted sleep and addressed cross-species consequences via comprehensive metabolite profiling. Serum from sleep-restricted rats was analyzed using polar and nonpolar methods in two independent datasets (n = 10 per study, 3,380 measured features, 407 identified). A total of 38 features were changed across independent experiments, with the majority classified as lipids (18 from 28 identified). In a parallel human study, 92 metabolites were identified as potentially significant, with the majority also classified as lipids (32 of 37 identified). Intriguingly, two metabolites, oxalic acid and diacylglycerol 36:3, were robustly and quantitatively reduced in both species following sleep restriction, and recovered to near baseline levels after sleep restriction (P < 0.05, false-discovery rate < 0.2). Elevated phospholipids were also noted after sleep restriction in both species, as well as metabolites associated with an oxidizing environment. In addition, polar metabolites reflective of neurotransmitters, vitamin B3, and gut metabolism were elevated in sleep-restricted humans. These results are consistent with induction of peroxisome proliferator-activated receptors and disruptions of the circadian clock. The findings provide a potential link between known pathologies of reduced sleep duration and metabolic dysfunction, and potential biomarkers for sleep loss.center_img Citation: Study identifies two biomarkers for lack of sleep (2015, February 13) retrieved 18 August 2019 from https://phys.org/news/2015-02-biomarkers-lack.html Journal information: Proceedings of the National Academy of Sciences Recent studies have shown that lack of sleep may be a culprit for increased risks of several health issues including obesity, heart disease, and diabetes. One theory is that sleep deprivation causes metabolic changes including changes in the brain’s metabolic pathway. Sehgal, et al found two metabolites common in both rats and humans that change after chronic sleep restriction, oxalic acid and diacylglycerol 36:3. Both are byproducts of two different metabolic processes, but behave similarly when rats or humans lack sleep.For the human subjects and the rat models, a baseline reading of blood metabolite content was taken after a 12-hour fast and eight to 10 hours of sleep. Then, both groups were subjected to five days of sleep that was restricted to four hours per night. Blood was taken after one night to test acute sleep restriction and taken after five nights to test chronic sleep restriction. Finally, blood was taken after a “recovery” night of eight to 10 hours of sleep to see if the metabolic profile returned to baseline levels.While there was variation in metabolite composition between humans and rats, both showed an increase in phospholipids after acute and chronic sleep restriction. The particular phospholipids varied between the two, but indicated that under restricted sleep, the metabolic processes are operating in an oxidative environment. Both rats and humans showed a distinct decrease in oxalic acid and diacylglycerol 36:3 levels. Additionally, both showed a return to baseline levels for most, but not all, metabolites after a recovery night.The reasons for reduced oxalic acid levels are likely from reduced synthesis or increased gut microbiota processing, and not from dietary intake. It is unclear why diacylglycerol levels are reduced in both humans and rats. Even though more studies are needed to determine why these levels decrease in both humans and rats, because oxalic acid and diacylglycerol 36:3 responded similarly in both species, they can serve as biomarkers for sleep loss.Other results were species specific. After chronic sleep restriction, the rats had indicators of oxidative stress, which is due to the buildup of oxidants that are typically removed after sleeping, but humans did not show oxidative stress after four hours of sleep per night. Prior studies had shown that completely sleep deprived, humans showed signs of oxidative stress. This suggests that humans may be able to counteract the effects of oxidative stress with less sleep more easily than rats. The human subjects did show elevated levels of the amino acids, tryptophan and phenylalanine, both of which are precursors for neurotransmitter production, suggesting that amino acid metabolism is affected by sleep restriction. This study elucidates some of the effects sleep restriction has on metabolic processes. Sleep restriction affects several different processes in the body and chronic sleep restriction likely induces an oxidative environment. Additionally, two biomarkers were found that can aid in further studies. Explore furtherlast_img read more

Superdry reforming reaction converts greenhouse gases to useful intermediates

first_img New approach to dynamically tune how a catalyst operates More information: L. C. Buelens et al. Super-dry reforming of methane intensifies CO2 utilization via Le Chateliers principle, Science (2016). DOI: 10.1126/science.aah7161AbstractEfficient CO2 transformation from a waste product to carbon source for chemicals and fuels will require reaction conditions that effect its reduction. We develop a “super-dry” CH4 reforming reaction for enhanced CO production from CH4 and CO2. We used Ni/MgAl2O4 as a CH4 reforming catalyst, Fe2O3/MgAl2O4 as a solid oxygen carrier, and CaO/Al2O3 as a CO2 sorbent. The isothermal coupling of these three different processes resulted in higher CO production compared with conventional dry reforming by avoiding back reactions with water. The reduction of iron oxide was intensified by CH4 conversion to syngas over Ni and by CO2 extraction and storage as CaCO3. CO2 is then used for iron reoxidation and CO production exploiting equilibrium shifts effected with inert gas sweeping (Le Chatelier’s Principle). Super-dry reforming utilizes up to three CO2 molecules per CH4 and offers a high CO space-time yield of 7.5 mmol CO per second per kilogram of iron at at 1023 Kelvin.

The content is provided for information purposes only. Explore further Researchers from Ghent University in Belgium, led by Dr. Vladimir Galvita have developed a nickel-catalyzed carbon reforming reaction scheme that involves the use of calcium oxide as a carbon dioxide sorbent and iron oxide as a solid oxygen carrier. This process does not involve temperature swings, allowing for better carbon monoxide production, and their two-flow system eliminates unwanted back reactions. Their work appears in a recent issue of Science.In an effort to decrease CO2 production, scientists have developed methods to convert CO2 to helpful starting materials that can be used to produce synthetic energy sources. These methods involve reducing CO2. The most commercially feasible method is a process called dry reforming of methane, which produces syngases, CO and H2. This reaction needs to be a “dry” reaction because in the presence of water, the more energetically favored water gas shift reaction occurs. In this reaction carbon monoxide reacts with water to re-form carbon dioxide. Eliminating water from these reactions has proved to be an active area of research.In the current study, Buelens et al. used calcium oxide as a CO2 sorbent in which calcium carbonate is formed. This has several benefits that that has allowed a higher carbon monoxide yield and an opportunity to remove water that is formed from the oxidation of methane. First, from an economic and practical standpoint, because CO2 is removed in situ, the feed gas can be of lower stock quality. Secondly, the formation of calcium carbonate can be coupled with methane reformation and iron oxide reduction resulting in a more energetically favorable process. Then, when calcium carbonate decomposes into CO2 and CaO, the carbon dioxide is reduced to CO over the iron oxide oxygen carrier. According to the authors, it is at this point that the feed is switched to inert gas to regenerate the system. They obtained a 45% higher CO yield, but this yield could be even higher by optimizing conditions. The higher efficiency of this reaction is due in large part by employing Le Chatlier’s Principle. Importantly, their two-flow reaction set-up seems to have some versatility that prior dry reforming reactions lacked either by changing the gas feedstock ratios or by changing to a multi-reactor configuration.The applications of this technique, according to lead author, Lukas Buelens is that “with this process, we intensify the conversion of CO2 by making maximal use of CH4 as reducing gas. The generated CO can be used directly or combined with a green H2 source for the production of chemicals or fuels.”Additionally, their initial flow system uses a less expensive nickel catalyst because carbon deposition has been eliminated. Their system is more efficient for CO2 utilization than prior dry reforming reactions and may serve as a model for optimized CO2 conversion.
