Frost flowers in the laboratory: growth, characteristics, aerosol, and the underlying sea ice

first_imgIn the laboratory, we have investigated the growth and composition of frost flowers. Their ionic composition has shown little difference from those of field measurements. Young frost flowers grown on sea ice are saline, leading us to speculate that wicking occurs continually during their growth on sea ice. The surface area of frost flowers is only a little larger than the area of ice underneath, consistent with recent field measurements from the Arctic. Time-lapse photography has allowed us to observe the extreme mobility of freshly forming sea ice, at the stage at which the mush has become rather solid, and continuing while the flowers grow. This mobility results in new brine being expelled to the surface, which therefore remains wet. During various stages of frost flower growth, we observed their freshly formed dendritic parts rapidly diminishing in size after contacting the surface, consistent with repeated wicking. Frost flowers proved to be very stable in the presence of wind, such that no aerosol was observed when wind was blown across them in the laboratory chamber. This is consistent with recent field observations of frost flowers coexisting with wind-blown snowlast_img read more

HollyFrontier Corporation to build new renewable diesel refinery project

first_img Image: HollyFrontier to build new renewable diesel refinery project. Photo: Courtesy of Harry Stilianou/Pixabay HollyFrontier Corporation today announced a series of strategic actions targeting growth, risk management and shareholder returns: a new renewable diesel unit (“RDU”) project, regular dividend annual growth target and a new HollyFrontier share repurchase authorization.Commenting on the announcements, Franklin Myers, Chairman of the Board of HollyFrontier, stated, “Today’s announcements illustrate HollyFrontier’s commitment to both grow our business and deliver superior cash returns to shareholders. We expect our new renewable diesel plant will generate attractive returns and help us meet our requirements under the Renewable Fuel Standard. At the same time, we are increasing cash returns to shareholders through an increase in our regular dividend with a path for future dividend growth and a new HollyFrontier share repurchase authorization.All of these actions are consistent with our balanced approach to capital allocation: 1) reinvest in and maintain our existing assets, 2) maintain a healthy balance sheet with an investment grade credit profile, 3) pay a competitive and sustainable regular dividend through the cycle, 4) invest in growth capital projects or acquisitions with a superior return, and 5) return excess cash to shareholders through share repurchases.”Construction of a Renewable Diesel UnitHollyFrontier plans to construct a new RDU at its Artesia refinery. The RDU will have a production capacity of approximately 125 million gallons a year and allow HollyFrontier to process soybean oil and other renewable feedstocks into renewable diesel. This investment will provide HollyFrontier the opportunity to meet the demand for low-carbon fuels while covering the cost of our annual RIN purchase obligation under current market conditions. The RDU, along with corresponding rail infrastructure and storage tanks, is estimated to have a total capital cost of $350 million, and is expected to be completed in the first quarter of 2022. The RDU will be funded with cash on hand and is expected to generate an internal rate of return between 20% and 30%.Regular Dividend Annual Growth TargetOn November 13, 2019, HollyFrontier announced that its Board of Directors declared a regular quarterly dividend of $0.35 per share, an increase of 6% from $0.33 per share the prior quarter, payable on December 11, 2019 to holders of record of common stock on November 27, 2019. Over the next three years, HollyFrontier plans to review the dividend annually and target an expected dividend growth rate of approximately 5% per year.New HFC Share Repurchase AuthorizationHollyFrontier’s Board of Directors authorized a new $1 billion share repurchase program. This authorization replaces all existing share repurchase authorizations, of which there was approximately $281 million remaining. Over the past 15 months, HollyFrontier has returned over $719 million to shareholders under its previous share repurchase program and reduced the outstanding share count by 8%. Share repurchases may be made in the open market, through privately negotiated transactions from time to time or by other means in accordance with federal securities laws and are subject to a number of factors, including market conditions, applicable legal and regulatory requirements and other considerations. This share repurchase program may be discontinued at any time by the Board of Directors.

Holcomb Picks New Child Services Director, Calls For Assessment Of Agency

first_imgFacebookTwitterCopy LinkEmailShare Staff ReportTheStatehouseFile.comINDIANAPOLIS—Gov. Eric Holcomb has named a veteran health professional to lead Indiana’s Department of Child Services and is calling for a complete assessment of the agency.Holcomb named Terry J. Stigdon, who has worked at Riley Hospital for Children for nearly 20 years, as the next director of DCS, effective Jan. 22. Stigdon replaces Mary Beth Bonaventure, who quit after saying that she was no longer able to protect the children in the care of the agency because of budget cuts.“I choose to resign, rather than be complicit in decreasing the safety, permanency and well-being of children who have nowhere else to turn,” Bonaventure said in a letter to the governor.Former Gov. Mike Pence appointed Bonaventure, who had 31 years of experience in the Lake County juvenile system, to lead the agency in 2013.Stigdon comes to the role with extensive experience at Riley Hospital where she is currently the clinical director of operations, overseeing strategy, finance, personnel, research and programs for several of the hospital’s key divisions.Terry J. Stigdon has been named to lead Indiana’s Department of Child Services. Photo provided by governor’s office.“Terry has in-depth, firsthand experience in the issues faced by the children and families served by Indiana’s Department of Child Services,” Holcomb said in a statement. “She has dedicated her life to saving and improving the lives of young Hoosiers, and she will bring a passion for this critically important work.”Stigdon has worked at Riley since 1998, where she began as a pediatric intensive care staff nurse before taking on progressively greater managerial responsibilities over the next two decades.“I am honored by this incredible opportunity to put my experiences and passions to work as never before to improve the lives of children and families around the state,” Stigdon said in a statement.Stigdon has earned associate and bachelor’s degrees in nursing as well as a master’s degree in nursing leadership and management.Sam Criss, current DCS deputy director, will serve as interim director for the agency.Holcomb has also announced that he has asked a national nonprofit organization that specializes in improving child and family outcomes to conduct an assessment of DCS. That assessment, conducted by the Child Welfare Policy and Practice Group, will begin its work on Jan. 3.The group has conducted similar projects in 20 other states. In Indiana, it has been asked to assess:Are systems in place to assure that children and families are healthy and safe?Is funding being utilized in the most appropriate ways to best serve children and taxpayers?Are caseloads appropriate for staffing levels? What staffing adjustments should be made?Are DCS program outcomes appropriate for services provided to Indiana children and families?How do Indiana’s case load numbers, costs and program outcomes compare to other states and the nation?The DCS assessment is expected to be complete and delivered to the governor and the new director in spring of 2018. It will be used to inform future operations of DCS to ensure state resources are deployed most effectively so that all Hoosier children in need of services are kept safe and healthy.Indiana House Democratic Leader Terry Goodin of Austin issued a statement saying he had asked for a complete assessment of DCS and believes the legislature should be involved in the process.“If the governor doesn’t want us to take part in his review, then the Legislature must study the situation on its own,” Goodin said in a statement. “Committees in both chambers should conduct hearings on this matter, and figure out if there is a need for legislative remedies.”FOOTNOTE:TheStatehouseFile.com is a news website powered by Franklin College journalism students.

HGCA points to importance of provenance

first_imgNew research commissioned by the Home Grown Cereals Authority (HGCA) has revealed that the bakery sector is under-playing the provenance card in product marketing.Based on interviews through seven focus groups, the research found that bread and morning goods fell behind the brewing and dairy industries over perceptions of provenance claims, which ranged from supporting the local community through regionality or Britishness, natural ingredients, the origins of food including named suppliers, heritage and tradition and environmental standards.Richard Walters, head of food marketing at Bidwells Agri- business, which carried out the research, said: “In bread and morning goods, our research identified an opportunity for manufacturers to use provenance to underline the health benefits and freshness of product – linking to the farm and natural ingredients. There’s already product differentiation between healthy products within bakery, and provenance is a way to better target consumers buying into that market.”He added that there was further potential around regionality, following Morrisons and Sainsbury’s initiatives to source local wheats for regional stores.Roz Reynolds, marketing manager at the HGCA, added: “It may only be possible in certain parts of the bakery market to achieve that 100% feel for provenance, but it is very powerful in those parts, and it’s worth exploring within your own business.”last_img read more

HSPH, Ministry of Health of India formalize collaboration on public health issues

first_imgIndia faces daunting public health challenges. Maternal and infant mortality rates are high. Malaria and tuberculosis persist stubbornly. Noncommunicable diseases such as diabetes and cancer are prevalent and increasing. And many—especially the poor—lack good and affordable health care.Keshav Desiraju, secretary of health for the Ministry of Health and Family Welfare in India, and Harvard School of Public Health (HSPH) faculty gave an overview of India’s current and future public health challenges at an HSPH seminar on May 9, 2013. Introducing Desiraju, HSPH Dean Julio Frenk said he is described by colleagues “as a visionary and a man of action, with enormous capacity to articulate complex ideas.”Desiraju’s talk featured the signing of a memorandum of understanding (MOU) between India’s Ministry of Health and Family Welfare and HSPH, which formalizes a closer working relationship between the School and the ministry on a variety of public health issues. Ties between HSPH and India are longstanding, said Wafaie Fawzi, chair of the HSPH Department of Global Health and Population (GHP).“Many of us at the School—faculty, students, and staff—have had the privilege of working with institutions and partners in India for mutual benefit on issues of critical importance to global health such as the impact of urbanization, the effectiveness of health interventions, and issues around nutrition research and training,” Fawzi said.

ND Glee Club tours internationally over fall break

first_imgThe Glee Club took its talents on tour this fall break when they performed in two concerts in Michigan, two in western New York and one in Toronto. The all-male a capella group will also give its annual fall concert Friday at 8 p.m. in the DeBartolo Performing Arts Center. Stuart Streit, a sophomore member of Glee Club, said the concert in Rochester, New York, was his favorite of the five performances. “A huge crowd turned out for [the Rochester concert], and I thought we had done a really good job,” Streit said. “It was one of our first times off-book, which means we weren’t reading our music while singing, which led us to engage the audience a little bit more and keep our eyes on our director, which led to us singing better.” Streit said the wide range of music in the group’s concert repertoire contributed to the tour’s success. “We had some Canadian folk songs and a lot from our regular repertoire, so a lot of spirituals, some sacred music, [and] we had some Russian and German songs on this one,” he said. In addition to the Fall Tour, the group performs during spring break and travels internationally every other year, junior and Glee Club secretary Michael Shakour said. The club gives brief concerts on football weekends at the reflecting pool in front of Hesburgh Library, and it also performs longer concerts on campus.   “We perform … main concerts [four times] a year: fall, three at Christmas, spring and then a commencement concert,” Shakour said. “We’ll perform anything from classical music to spiritual to jazz. … Anything that has the words ‘Notre Dame’ in it we’ll sing. “We perform at least once a year with generally an orchestra and another singing group around campus or at Saint Mary’s.” Senior and Glee Club vice president Tim Kenney said the fall concert program will contain much of the same music the group performed on its recent tour. “In addition [to the tour music], for our second half we’ll have a couple small groups.” Kenney said. “There’s one quartet that a couple of the guys organized, … and then the Undertones do a set. “It’s a lot of fun. We’ve all spent a lot of time working on the music, been working on it the entire semester so far, put in a lot of rehearsal hours. It’s a really strong set of music that’s going to be really well-done.” Though the Glee Club has a vigorous, four-days-a-week practice schedule, Kenney said the singers don’t mind because they’re like a family now. “The community has been really exciting and really just wonderful,” Kenney said. “It’s such a tight-knit group of guys. We really do consider ourselves a brothership. Being able to have that close of interaction … having 80 best friends on campus, it’s really just awesome.” tThe Glee Clubssells CDs,at gleeclub.nd.edu,and at the Hammes Notre Dame bookstore. CDs will also bedavailable at Friday’s concert, which costs $10 for general admission, $6 for seniors and $5 for students. Contact Emma Borne at [email protected]last_img read more

Indian state of Maharashtra says no to new thermal power plants, pushes renewables

first_img FacebookTwitterLinkedInEmailPrint分享ETEnergyWorld.com:Energy minister Nitin Raut has announced that no more thermal power generation units would be set up in [Maharashtra] as there is a huge gap between supply and demand due to the coronavirus pandemic-induced recession.Maharashtra State Electricity Distribution Company Limited (MSEDCL) has signed power purchase agreements (PPAs) for 35,000MW, but is purchasing only 14,500MW due to low demand.Maharashtra Electricity Regulatory Commission (MERC) has set a target for MSEDCL of meeting 25% of its demand from renewable sources in next five years. Hence, the government has decided to promote renewable energy only.Civil supplies minister Chhagan Bhujbal and MLAs of Deolali, Igatpuri and Amalner had met Raut urging him to replace the old units in Nashik thermal power station by a new unit of 660MW. The energy minister turned down this demand.Earlier, deputy chief minister Ajit Pawar had rejected proposal to set up two new 660MW units at Koradi. He had told Raut to set up solar power plants instead as it is cheaper. Raut then chalked out plans to set up several solar power plants in the state in three phases.Raut told Bhujbal that power demand had gone done by 33% and several thermal units were lying idle. However, MSEDCL had to pay fixed charges to the generation companies for these units, which was a huge burden on power consumers. He further said the generation cost of old units was very high and hence MSEDCL could not purchase power generated by these units under merit order dispatch (MOD) regime. Same was the case with new units as capital cost was very high. So, it was not possible to set up a new unit at Nashik, he said.[Ashish Roy]More: Maharashtra: No new thermal power units in state, says Raut Indian state of Maharashtra says no to new thermal power plants, pushes renewableslast_img read more

CU 2.0 Fintech Friday: CU Student Choice

first_imgIt’s CU 2.0 Fintech Friday! Today, Chris Otey sits down with CU Student Choice to discuss all things credit union, fintech, and digital innovation.CU Student Choice works with credit unions to provide prospective university students with student loans. Their goal is to simplify the college loan process for students. This simplification, they hope, will help students find good-value educational loans to finance their education. They also make it so that the borrower doesn’t have to reapply for loans each year.For all of us who have taken out federal student loans at some point—that setup sounds like a breath of fresh air. Nobody likes filling out FAFSA forms year after year.It sounds even better for those of us who took out private student loans. The interest rates on those often exceed any reasonable boundaries.
