We demonstrate, for the first time, continuous real-time observations of airborne bio-fluorescent aerosols recorded at the British Antarctic Survey’s Halley VI Research Station, located on the Brunt Ice Shelf close to the Weddell Sea coast (lat 75°34′59′′ S, long 26°10′0′′ W) during Antarctic summer, 2015. As part of the NERC MAC (Microphysics of Antarctic Clouds) aircraft aerosol cloud interaction project, observations with a real-time ultraviolet-light-induced fluorescence (UV-LIF) spectrometer were conducted to quantify airborne biological containing particle concentrations along with dust particles as a function of wind speed and direction over a 3-week period. Significant, intermittent enhancements of both non- and bio-fluorescent particles were observed to varying degrees in very specific wind directions and during strong wind events. Analysis of the particle UV-induced emission spectra, particle sizes and shapes recorded during these events suggest the majority of particles were likely a subset of dust with weak fluorescence emission responses. A minor fraction, however, were likely primary biological particles that were very strongly fluorescent, with a subset identified as likely being pollen based on comparison with laboratory data obtained using the same instrument. A strong correlation of bio-fluorescent particles with wind speed was observed in some, but not all, periods. Interestingly, the fraction of fluorescent particles to total particle concentration also increased significantly with wind speed during these events. The enhancement in concentrations of these particles could be interpreted as due to resuspension from the local ice surface but more likely due to emissions from distal sources within Antarctica as well as intercontinental transport. Likely distal sources identified by back trajectory analyses and dispersion modelling were the coastal ice margin zones in Halley Bay consisting of bird colonies with likely associated high bacterial activity together with contributions from exposed ice margin bacterial colonies but also long-range transport from the southern coasts of Argentina and Chile. Dispersion modelling also demonstrated emissions from shipping lanes, and therefore marine anthropogenic sources cannot be ruled out. Average total concentrations of total fluorescent aerosols were found to be 1.9 ± 2.6 L−1 over a 3-week period crossing over from November into December, but peak concentrations during intermittent enhancement events could be up to several tens per litre. While this short pilot study is not intended to be generally representative of Antarctic aerosol, it demonstrates the usefulness of the UV-LIF measurement technique for quantification of airborne bioaerosol concentrations and to understand their dispersion. The potential importance for microbial colonisation of Antarctica is highlighted.
Just a week or so ago, we reported on a story which claimed that Arcade Fire had finished working on new music. The band officially validated those claims by releasing a brand new track, “I Give You Power,” featuring vocal contributions from the legendary Mavis Staples. The new track is the band’s first in nearly four years, and a strong indication that more tunes are on the way!The track was released via TIDAL, and all proceeds from purchasing the track will go to ACLU. You can stream it below. The track also came with some artwork that you can see below.
Pappu worked to find the secret of when the thrips can transmit TSWV. He’s usingnew biotech methods to detect specific proteins that appear only when the insect cantransmit the virus. And they’re doing it quickly. “The presence of the viral protein is a good indication that the insect was capable oftransmitting the virus,” Pappu said. Pappu points out, too, that the 10 percent average is just that. “Some farmers lost only1 percent or 2 percent,” he said. “Others may have lost close to 50 percent.” The three main crops the virus affects are peanuts, tobacco and tomatoes. But manyothers are affected. In these three crops alone, Georgia farmers lost $63.8 million in1996. The virus affects the crops differently, but the results are the same: decreasedyields and crop loss. Viruses rely on carrier insects, he said. The TSWV relies on tiny insects called thripsto move from plant to plant and field to field. “Tomato spotted wilt virus is the No. 1 problem in the state’s crops,” said Hanu R.Pappu, a plant pathologist at the Coastal Plain Experiment Station. “Last year alone, itcaused an average 10 percent loss in many affected crops.” Past efforts to control tomato spotted wilt by controlling the insects didn’t work. “Wejust didn’t know at the time that only certain populations were transmitting,” he said. The first problem farmers have with the virus is knowing when it’s in their fields.Since it’s a virus, Pappu said, there’s no cure. The method he uses is called TAS ELISA; Triple Antibody Sandwich, Enzyme-LinkedImmunoSorbent Assay. It uses virus-specific antibodies that reveal if viral proteins arein the insect. In past years, Georgia farmers had a tough row to hoe in many crops in fighting thedeadly tomato spotted wilt virus. Now, new technology can give them an edge inmanaging the virus. But while about a dozen species of thrips live in Georgia, only two can transmitTSWV. “And those two species can transmit the virus only when the insect wasinfected as a juvenile,” Pappu said. For the first time, Georgia scientists can learn in just one day if insects in the field areactually transmitting the virus. Pappu is working with another plant pathologist and an entomologist at the experimentstation to learn the secrets of the virus that causes tomato spotted wilt. Once they learnits secrets, they can use them to fight against the tiny but destructive organism. Before, scientists needed six to eight weeks to find out if a thrips population wastransmitting the virus. “Now this technology can tell us in one to two days,” he said. “So prevention is extremely important,” he said. “There is no control, so we’re tryingto get it to a point where we can manage the disease through other means.” Pappu’s goal is to forecast when a transmitting population is moving into a field.Armed with that knowledge, farmers can apply pesticides to kill the insects before theycan transmit the virus into the plants. “This information will allow them (farmers) to be more precise in applying chemicals,”Pappu said. “To be effective with our applications, we needed an efficient, quick wayto know if the population was transmitting.” Now they have it.
Credit unions have heard it for years now—“you’ve got to be on social media.” Many credit unions have recognized this necessity and are active on multiple social media platforms, including Facebook, Twitter and YouTube. Is it making the impact they are hoping for?“According to a survey fielded by Third Degree Advertising, 41% of credit union marketers think social media is very important to their marketing strategy and 74% said their organization intends to increase its level of social media use in the future. Yet 53% of respondents rated their credit union’s social media efforts as not effective in helping them achieve marketing goals.” continue reading » 20SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr
The House Financial Services Committee passed a host of NAFCU-backed regulatory relief bills out of committee yesterday following a two-day mark-up that addressed Home Mortgage Disclosure Act (HMDA) improvements and tailoring of regulations to limit burdens on affected institutions. One approved bill would also raise the CFPB supervision and examination threshold from $10 billion to $50 billion.“We thank Chairman [Jeb] Hensarling and the committee for recognizing the regulatory burden facing today’s credit unions and for advancing legislation that would provide some regulatory relief,” said NAFCU President and CEO Dan Berger. “We are pleased to see a number of these bills get bipartisan support and look forward to continuing to work with lawmakers as these bills now await House action.”NAFCU Vice President of Legislative Affairs Brad Thaler sent a letter to the committee on Tuesday, urging action on the regulatory relief measures that would help credit unions. 9SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr continue reading »
Credit unions tend to be on the forefront of financial health; implementing enterprise-level and consumer-centric strategies, designing high-quality products and services, and measuring their members’ outcomes so they can pursue long-term opportunities. However, the landscape in and around financial services is shifting dramatically with the emergence and application of new disruptive technologies.To help credit unions understand this ever-changing landscape, the Foundation partnered with Members Development Company (MDC) and the Financial Health Network (FHN) in 2019 to research emerging technologiesand how they will help credit unions grow, meet their members where they are in life and provide them with new opportunities.

Facebook Indonesia tourism hotels restaurant impact coronavirus epidemic loss LOG INDon’t have an account? Register here Forgot Password ? Topics : Linkedin Log in with your social account The Indonesian tourism sector has suffered losses of at least US$1.5 billion since January as cancelations have hit the industry, especially hotels, amid growing fears over the outbreak of the novel coronavirus, an industry source has said.Chairman of the Indonesia Hotel and Restaurant Association (PHRI) Hariyadi B. Sukamdani said that of the total estimated losses, about $1.1 billion occurred as a result of cancelations made by tourists from China and the remaining $400 million resulted from cancelations made by tourists from other countries.“The losses are growing as people prefer to stay at home rather than going on vacation,” Hariyadi, who also chairs the Indonesia Employer’s Association (Apindo), said in Jakarta on Thursday.He said that other related businesses such as the suppliers of hotels for their daily operations, which mostly comprise small- and … Google

Australia’s big four banks were all part of the inquiry which is looking into residentialA FEDERAL inquiry investigating the decision making processes of Australia’s biggest banks has found that public outcry was sometimes the only thing preventing them from pushing mortgage rates higher.And the interim report of the Australian Competition & Consumer Commission’s residential mortgage price inquiry also highlighted the need for greater transparency in mortgage rate discounts offered by the banks.The interim report, out today, pointed to public criticism and media attention acting as a handbrake on bank ambitions to raise rates to boost margins.“Expectations of strong public reaction have acted as a constraint on pricing decisions,” it said, “ … without this reaction residential mortgage interest rates could have been higher and/or increases could have been introduced earlier.”“ … In one case, for example, an Inquiry Bank began considering an interest-rate increase, but staff recommended deferring any increase until a ‘trigger event’ occurred (either an Official Cash Rate change or a rate change by a big four bank) due to concerns about adverse publicity,” the report said. “At a different Inquiry Bank, as another example, a proposal to increase fees was substantially modified due to concern about reputational damage.”The inquiry also warned that there were “signs of a lack of vigorous price competition” among the Big Four banks in particular.“The internal documents of the Inquiry Banks reviewed by the ACCC to date reveal a lack of vigorous price competition between the Inquiry Banks, and the big four banks in particular.More from newsParks and wildlife the new lust-haves post coronavirus20 hours agoNoosa’s best beachfront penthouse is about to hit the market20 hours ago“The pricing behaviour of each of the Inquiry Banks appears more consistent with ‘accommodating’ a shared interest in avoiding the disruption of mutually beneficial pricing outcomes, rather than consistently vying for market share by offering the lowest interest rates.”The Big Four banks make up the lion’s share of the market, around three quarters.The Australian Banking Association was quick to defend competition levels in the banking sector, stating there were “over 140 providers, offering over 4,000 home loan products”.“Truly a vast and competitive market for Australians to choose a home loan.”It also said there were “very high levels of discounting in the Australian home loan market”.“It’s clear that competition is delivering better deals for customers, shopping around works and Australians should continue to do so to get the best discounts on the advertised rate.”The ABA said Galaxy research had found that three million people had switched banks in the last three years — with two-thirds finding that “switching was an easy process”.The ACCC was expected to issue its final report after the end of this financial year, delving into how the banks passed on the cost of the Major Bank Levy, as well as how smaller lenders can compete with bigger banks and how consumers can change residential mortgage pricing.
