Cooling process recorded in subglacially erupted rhyolite glasses: rapid quenching, thermal buffering, and the formation of meltwater
The thermal histories of two subglacial rhyolite glasses from Torfajokull complex of south central Iceland have been determined from changes in the relaxation of enthalpy in the calorimetric glass transition interval. Heat capacity measurements of bulk glass samples from Raudufossafjoll (sample number JS.1.1) and Blahnukur (sample number JS.2.1) by differential scanning calorimetry show marked differences in the temperature of the onset of glass transition (Tg) on reheating. The average Tg is 750 K for JS.1.1, whereas it is 850 K for JS.2.1. These differences in the onset of Tg are related to quench rate through considerations of the activation energy and timescales for structural relaxation modeled, using the Kohlrausch-Williams-Watt function. Multiple glass samples from the two Torfajokull locations recover different average values and distributions of a fictive temperature, T-f, which we interpret in terms of differences in the thermal histories of the glasses. In both glass samples the range of fictive temperatures and, by implication, apparent cooling rates, is lower than those estimated for a glass rapidly quenched by contact with cold (glacial melt) water and requires that the glass was annealed at temperatures in the glass transition interval associated with relaxation times of the order of 1000-10,000 s. The complex cooling histories of the Torfajokull samples show that the products of subglacial eruptions may be held at elevated temperatures for several hours and, as a result, may drive vigorous convection in the ice-bound vaults above erupting rhyolite deposits.

Well-known industry website supplier Jamie Arthur has taken the plunge and launched a property portal for upmarket agents based on a revenue-share model.The 40-year-old, who already runs a successful digital consultancy for UK and overseas estate agents called Property Webmasters, is to now take on platforms like PrimeLocation with his own portal.Propuno is free to list for agents and for the moment is working with a selected number of European and UK luxury property agents.But Jamie says he wants to eventually expand fully into the UK and Propuno is attracting leads for property in some of the most competitive landscapes in the world including the Costa Del Sol, Paris and Cannes to name a few.Based in Hartlepool, the portal has been created by the same tech team behind Property Webmasters and says it will offer buyers the chance to “work with ethical, professional and trustworthy estate agents in the UK and overseas”, he says.While it’s been in pre-launch mode Propuno says it has already been visited by a million people and that its agents in France, Cyprus, Portugal, Spain and the UK have already secured sales from its leads.ReservationsLuke Fleming, its Digital Marketing Manager, says: “We understand that customers have reservations about which estate agents to deal with, for that reason we wanted to ensure we work only with reputable estate agents who are providing the highest quality service in their specific areas around the world.“Drawing upon our marketing and website expertise, we advertise and list our clients’ properties for free on their behalf; this allows us to focus on our strengths whilst also freeing up more time for our agents to focus on what they’re best at.“We have introduced a revenue-share model where we receive a commission on any resulting sale, we don’t profit unless our agents do.”propuno jamie arthur PrimeLocation November 5, 2020Nigel LewisWhat’s your opinion?

CCOMSEx added that the most highly sensitive systems and informational assets are institutions directly involved with cybernetic security and defense, such as Area Defense Coordination Centers (CCDA); Integrated Centers for Regional Command and Control (CICCR); CDCiber; the Ministry of Defense; and the Navy, Army, and Air Force. CDCiber, which security authorities created in September 2012, is an organization within the Brazilian Army that’s responsible for coordinating and integrating cybernetic defense activities under the umbrella of the Ministry of Defense. During the Olympics, which will be held from August 5th-21st, CDCiber will be at the forefront of the activities that will bring together 200 members from all three branches of Brazil’s Armed Forces and other partner security agencies. CDCiber’s mandate is to fight against threats in cyberspace that could undermine the games. During the latest large events that Brazil has hosted, the main offenses were the abuse of public and private websites, wherein the page was hacked and content changed; virus alerts and hosting; and cases involving sites that were defaced or maliciously taken offline. On November 8th, the Army detected hackers had entered servers belonging to the Army’s network and leaked Natural Persons Registry (CPF, for its Portuguese acronym) numbers – a unique 11-digit number assigned to each individual – belonging to military personnel, as well as passwords they used to access Army web pages. CCOMSEx publicly stated that the breach did not compromise strategic defense systems and that the Army’s Coordination Center for the Response to Internet Offenses was handling the case. “The working model of the Center for Cybernetic Defense (CDCiber) will, in essence, continue unchanged since it has proven to be a successful strategy,” the Brazilian Army’s Social Communication Center (CCOMSEx) stated. “Small changes in the strategy do take place, though, as fruit of the lessons learned during the previous events. We are constantly broadening capabilities and perfecting processes.” By Dialogo December 22, 2015 Brazilians’ thinking in general is that military forces would be inert/stagnant, given the entry of weapons and drugs and the fact that the local police are drying ice in the hot sun (i.e., doing things that are completely unnecessary and counterproductive). However, I see with pleasure that it’s not exactly like that. There are responsibilities. There were also a number of phishing attempts, in which a hacker tries to manipulate people into disclosing private information. For example, one phishing attempt could be a false e-mail from a “bank” asking for the user’s bank codes; if the intended victim provides the information, the perpetrator could clean out the account’s contents. During the Olympics, cyberspace defense activities will prioritize informational assets and systems according to how important they are to sustaining the event’s overall structure. Informational assets refer to the means of storage, transmission, and processing of data and information, in addition to the places where the information is stored and the people who have access to them, according to the “Military Doctrine on Cybernetic Defense,” published in 2014 by the Ministry of Defense. Brazilian Armed Forces plan on continuing to enforce the security concepts that succeeded in keeping the country safe from cyberattacks at the 2014 FIFA World Cup and the 2013 FIFA Confederations Cup during the 2016 Olympics in Rio de Janeiro. Strategic defense structures Countering threats in cyberspace Brazil highlighted cyberspace, along with nuclear and aerospace threats, as the three most strategic areas that need to be protected, according to the “National Defense Strategy” report in 2008. In Brazil, there is a popular saying: “one should not mess with a team that’s winning.” For the Olympics, the Armed Forces will adhere to this philosophy by using the same cybernetic defense strategy that helped provide public safety during the previous major sporting events. In the real world, attacks on “units” that are considered strategic for national defense such as ports, refineries, and hydroelectric power plants, could result in national catastrophes. However, Brazil has enacted important defense mechanisms to protect government databases and banks’ electronic systems, ensuring that the country would continue to run smoothly in the event of an attack. Since then, Brazil has launched a series of steps to protect cyberspace, which authorities define as “a virtual space, composed of computing devices – both connected to networks and not – from which digital information is transmitted and either processed or stored.” During the Olympics, these organizations’ domains (URLs), address books, and systems and services of partner organizations, such as the Federal Police and Brazilian Intelligence Agency (ABIN), will be protected.
by: Emma JohnsonBragging about being thrifty may get your props from your peers. But just because a decision appears to be a savvy money move doesn’t mean it actually nets savings. Here are seven things people do in the name of frugality that actually cost them money — or worse.Maintain membership in The Clean Plate Club. Just because it’s in your bowl doesn’t mean you have to eat it. If you’re full or it’s unhealthy, stop eating. Throw the rest away (or save for later). Your choice is obesity or throwing out food. Neither are great, but obesity will cost you in medical expenses and lost wages. Tossing out uneaten food will teach you to serve yourself smaller portions.Buy clothes that don’t fit (or you don’t like) because they’re on sale. It’s not a good deal if you don’t wear it. And (speaking from years of promising myself to lose that last 15 lbs already), if it doesn’t fit now, it won’t be in style when in may fit in the future (though it probably won’t ever fit).Manage your own investments. Yes, fees can eat away at your hard-earned savings. But unless you’re a financial professional, hire an expert to advise you on managing your finances (and there are some excellent arguments for why everyone should hire a neutral, non-emotional third-party). According to one recent study by managed accounts manager Financial Engines, 401(k) participants who paid extra for advice earned on average 3.32 percentage points more per year, net of fees, than those who managed their accounts themselves. continue reading » 1SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr
NCUA’s member business lending rule has been in effect for more than 5 months now, and credit unions are still working on implementing the rule’s changes. This month’s compliance feature in Credit Union Magazine examines new collateral and security requirements in section 723.5 of the regulation.The new rule allows credit unions to make their own risk-based decisions, as opposed to the strict loan-to-value limits and personal guarantee requirements.From an operation perspective, this means credit unions should focus on:Collateral: Sufficient capital is required, but the new rule states that collateral alone shouldn’t be the sole basis for granting a loan. The creditworthiness of the borrower and the marketability of the collateral determine the amount of collateral needed for each loan, and credit unions must establish standards, policies, and procedures to confirm, value, manage, and control collateral;LTV limits: Rather than specific ratios for each type of collateral, NCUA expects credit unions to set their own LTV ratio limits. These should be based on internal risk management analysis and accepted financial industry standards; and continue reading » 11SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr
“The company has taken several measures to improve its performance such as through [debt] restructuring and transformation,” he said in a statement on Friday.Earlier this year, Krakatau Steel received the green light from its creditors, mainly local banks such as state-owned Bank Mandiri and Bank Negara Indonesia, to restructure its loans totaling $2 billion in its bid to avoid bankruptcy.Silmy said earlier this year that the debt restructuring would cut interest payments to $466 million from $847 million. It is also expected to slash costs by around $685 million until 2027.The steelmaker also mentioned that the move to optimize its workforce, lower energy costs and slash spare part costs also contributed to the profit. State-owned steelmaker Krakatau Steel reported its first profit in eight years, thanks to its continuous measures to lower expenses.The company booked US$74.1 million in profit in the first quarter this year, a major switch from the $62.3 million loss it suffered in the same period last year, as its cost of revenue as well as general and administrative expenses dropped 39.8 percent and 41.5 percent respectively.Krakatau Steel president director Silmy Karim attributed the positive performance to the company’s concerted move to improve its performance since last year. Krakatau Steel’s operating expenses in the first quarter this year dropped 31 percent year-on-year (yoy) to $46.8 million. In total, the company claimed it had saved $130 million between January and March this year.However, Silmy expected the current economic condition induced by the COVID-19 pandemic to affect the company’s future performance this year.“Second quarter performance is expected to be different as the steel market weakened by 50 percent amid COVID-19 pressure,” he said.Steelmakers are facing severe blows to their business demand during the COVID-19 pandemic.The low demand is partially due to the large-scale social restrictions (PSBB) imposed by the government to contain the virus, which has led to the closure of businesses, including major steel-consuming businesses in the automotive and construction industries.“A weakening national economy has had a severe impact on the steel industry. If it continues further then we expect it will have a severe impact on [the company’s] full-year performance,” Silmy added.Krakatau Steel shares had risen 7.5 percent in Friday trading as of 13:08 p.m.Topics :
US LNG player Cheniere filed a request with the Federal Regulatory Energy Commission (FERC) to introduce fuel gas into the first liquefaction train at the Corpus Christi LNG project for commissioning. The company requested a permit be issued by no later than June 29, 2018, according to the filing to the commission.Cheniere noted in its filing that it has already filed the project commissioning plan for the Stage 1 with the regulator on May 25.According to an earlier monthly report, the Corpus Christi LNG Stage 1, which includes the first two liquefaction trains, two storage tanks, west jetty and east jetty civil work has reached an overall completion of 87.1 percent. Train 1 is projected to achieve substantial completion during the first half of 2019 with the second train to follow during the second half of 2019.The Corpus Christi project is a three-train liquefaction project under construction near Corpus Christi. Each train is expected to have a nominal production capacity of about 4.5 mtpa of LNG.The third train is part of Stage 2 of the project development currently at a 21.5 percent overall completion level.Cheniere has also set out plans for the construction of seven midscale liquefaction trains and an additional storage tank in the third stage of the project development. The Stage 3 project would increase the expected aggregate nominal LNG production capacity at the Liquefaction Project to approximately 23 mtpa.
