Southwest soars on fuel gambit

first_imgDALLAS – Southwest Airlines Co. reported a 54 percent jump in fourth-quarter profit as the bets it made on fuel prices allowed it to dodge for a little longer the spiraling costs that led to a $604 million loss for the parent of American Airlines, the nation’s biggest carrier. Revenue increased at both airlines, as planes were more crowded and average fares rose. Airline stocks rallied, led by American’s parent, AMR Corp., which rose 47 cents, or 2.5 percent, to close at $19.33 in trading on the New York Stock Exchange. Southwest shares added 89 cents, or 5.6 percent, to $16.76. Ray Neidl, an analyst with Calyon Securities, said the stocks were lifted by a decline in oil prices but said AMR also may have been rewarded for the strength of American’s route network and a slightly smaller-than-expected loss.

On Tuesday, the contract leapt $2.39 a barrel amid supply concerns spurred by possible sanctions against Iran, OPEC’s second-largest producer, and political unrest in Nigeria. Southwest said it earned $86 million, or 10 cents per share, in the fourth quarter, compared with $56 million, or 7 cents per share, a year earlier. Excluding one-time items, net income was $98 million, or 12 cents per share. Analysts had expected a gain of 13 cents per share, according to a survey by Thomson Financial. Revenue rose 20 percent, to $1.99 billion from $1.66 billion a year ago. Southwest again cashed in on a winning bet it made several years ago on the direction of fuel prices. The carrier bought options that locked in prices on most of its fuel needs through 2009, softening the blow of higher fuel costs. As a result of this hedging, Southwest paid about $1.20 per gallon for fuel – its second-biggest cost after labor – in the fourth quarter. But beginning this year, Southwest has less of its fuel hedged and at higher prices. For that reason, the carrier expects its average cost of fuel to rise to $1.45 a gallon in the first three months of this year. Still, Chief Executive Gary Kelly said the company has a favorable outlook on the first quarter and still expects profit to rise 15 percent this year. American Airlines was too weak financially to buy fuel options in recent years, and it paid the price in the fourth quarter – $2.02 per gallon. Parent AMR, which also owns the American Eagle commuter line, spent about $400 million more on fuel in the fourth quarter than it did a year earlier. That helped push Fort Worth-based AMR to its loss, which equaled $3.49 per share, after a loss of $387 million, or $2.40 per share, in the fourth quarter of 2004. Excluding $191 million in net one-time costs, AMR said it would have lost $413 million, $2.39 per share. On that basis, Thomson Financial said analysts were expecting a loss of $2.50 per share. Revenue rose 13.8 percent, to $5.17 billion from $4.54 billion a year ago, but that was below analysts’ consensus forecast of $5.24 billion. “We need to do more on both the cost and revenue sides of the ledger to return our company to sustained profitability,” said Chairman and Chief Executive Gerard Arpey. Michael Linenberg, an analyst for Merrill Lynch, said AMR did a good job of controlling costs other than fuel. The airline permanently grounded 27 jets at the end of the year. Both American and Southwest reported their planes were fuller than they were the year before. American’s average occupancy rate rose 3.6 points, to 77.9 percent, while Southwest’s gained 4.6 points, to 69.6 percent. Airline executives and analysts are counting on financially troubled carriers to cut back on flights, which could make planes even more crowded and push fares up. Yet there are signs that might not happen. A new airline, Virgin America, plans to begin flying between San Francisco and New York. And on Tuesday, Houston-based Continental Airlines Inc. hinted it may increase flights to combat rivals such as JetBlue Airways Corp. Southwest’s Kelly said high fuel costs made it an “enormous risk” to start a new airline. “Look at the results here for the fourth quarter and you may find that we are literally the only airline to make a profit,” Kelly said. “That to me sort of sums it up about starting a new airline.” American’s Arpey said he worried that carriers will respond to rising revenue by adding too many flights, which could depress fares and add to the industry’s financial troubles. “I’m very concerned that an industry that is chronically destroying capital is continuing to pour investment into the business,” he said. “I’m scratching my head over that.” However, that’s exactly what a few analysts, such as Neidl, and others like Robert Mann, an airline industry consultant in Port Washington, N.Y., are predicting. “If Continental does expand, we’ll see a me-too response,” Mann said. “It’s great news for travelers – more low prices,” he said. For all of 2005, Southwest earned $548 million, or 67 cents per share, compared with $313 million, or 38 cents per share, in 2004. Revenue rose to $7.58 billion from $6.53 billion. At AMR, the full-year loss was $861 million, or $5.21 per share, after a loss of $761 million, or $4.74 per share, in 2004. Revenue rose to $20.71 billion from $18.65 billion. 160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations!

The move has been met with praise from Buckeye fans, and members of the team. One key member of the program isn’t ready to fully commit to the move, however: head coach Urban Meyer. The three-time national champion told The Columbus Dispatch that reports of the official position change are a bit premature.“I haven’t made those decisions yet,” Meyer told The Dispatch. “It’s a little bit jumping the gun here. Braxton came to see me. He’s been talking to me about it (the switch). We’ve been working at it, but I’m not ready to say exactly how we’re going to use him yet.”Considering Pete Thamel’s SI report was based on a conversation with Miller, we have to imagine the move is, in fact, happening. Meyer is probably not thrilled that it was announced in July, giving Virginia Tech and others more than a month to prep for a J.T. Barrett or Cardale Jones-led offense, as well as figure out how to defend Miller as a skill guy. Otherwise, this would be a pretty crazy redirection by members of the Buckeye program.[Columbus Dispatch]last_img read more

Portfolio Minister, Senator the Hon. Ruel Reid, made the disclosure while addressing the opening of the Ministry’s inaugural Higher Education Summit on May 10 at the Jamaica Pegasus Hotel in New Kingston. The Government is looking to create an Integrated Higher Education System for Jamaica (IHES-J) aimed at better aligning training to industry demands. Story Highlights The Government is looking to create an Integrated Higher Education System for Jamaica (IHES-J) aimed at better aligning training to industry demands.Portfolio Minister, Senator the Hon. Ruel Reid, made the disclosure while addressing the opening of the Ministry’s inaugural Higher Education Summit on May 10 at The Jamaica Pegasus hotel in New Kingston.“This integration is expected to be supported with policies and systems to support greater autonomy, greater alignment to industry and a flexible approach to funding to support the needs of the institutions while ensuring that students are being trained in areas that are required by industry and will ultimately impact the economy,” he said.He said that despite deliberations over the years, limited progress has been made in addressing the need for greater integration of education and training.“Our hope is that coming out of these discussions (at the summit) we will be able to agree on the needed and significant steps forward together,” he said.The two-day summit, under the theme ‘Education 4.0: Disrupting Tradition…Transforming Jamaica’, provided a platform for stakeholders to discuss and provide feedback on a number of issues critical to the development of the higher education sector.From the consultations, the Ministry will seek to establish a declaration, which will encapsulate the core principles around which the Government will be able to define and pass legislation with regards to matters of governance, quality assurance and regulation of higher education.In his address, Senator Reid highlighted the importance of higher education to the development of the country.He said that among the national imperatives are (a) to increase the percentage of eligible cohort holding the minimum of a bachelor’s degree from 15 per cent to 80 per cent; (b)  remove barriers to access; and  (c) ensure that institutions are responsive to the changing dynamics and requirements of the labour market.Permanent Secretary in the Ministry, Dean-Roy Bernard, in his contribution, stressed that a key objective of the deliberations is to ensure that higher education is supporting the economic growth agenda.“We hear many times of the 67 per cent of our workforce that are untrained and uncertified. This summit is to ensure that we are reducing those numbers rapidly,” he said.Over the two days, experts in education and industry made presentations on a range of topics, including ‘Higher Education, Governance and the Oversight Framework’; ‘Autonomy within the Higher Education Sector’; ‘Funding the Higher Education Sector’; and ‘Relevance, Innovation and Leadership’.Among those in attendance were members of external quality assurance body, University Council of Jamaica (UCJ); regulatory body, Jamaica Tertiary Education Commission (J-TEC); the Council of Community Colleges of Jamaica (CCCJ) and their member institutions; and student representatives.last_img read more

KAIST research team finds cause of sepsisinduced lung injury

first_imgReviewed by Alina Shrourou, B.Sc. (Editor)May 7 2019A KAIST research team succeeded in visualizing pulmonary microcirculation and circulating cells in vivo with a custom-built 3D intravital lung microscopic imaging system. They found a type of leukocyte called neutrophils aggregate inside the capillaries during sepsis-induced acute lung injury (ALI), leading to disturbances and dead space in blood microcirculation.According to the researchers, this phenomenon is responsible for tissue hypoxia causing lung damage in the sepsis model, and mitigating neutrophils improves microcirculation as well as hypoxia.The lungs are responsible for exchanging oxygen with carbon dioxide gases during the breathing process, providing an essential function for sustaining life. This gas exchange occurs in the alveoli, each surrounded by many capillaries containing the circulating red blood cells.Researchers have been making efforts to observe microcirculation in alveoli, but it has been technically challenging to capture high-resolution images of capillaries and red blood cells inside the lungs that are in constant breathing motion.Professor Pilhan Kim from the Graduate School of Medical Science and Engineering and his team developed an ultra-fast laser scanning confocal microscope and an imaging chamber that could minimize the movement of a lung while preserving its respiratory state. They used this technology to successfully capture red blood cell circulation inside the capillaries of animal models with sepsis.During the process, they found that hypoxia was induced by the increase of dead space inside the lungs of a sepsis model, a space where red blood cells do not circulate. This phenomenon is due to the neutrophils aggregating and trapping inside the capillaries and the arterioles. It was also shown that trapped neutrophils damage the lung tissue in the sepsis model by inhibiting microcirculation as well as releasing reactive oxygen species.Related StoriesAPPG report highlights need to improve identification and treatment of sepsisStudy explains why several clinical trials of treatments for sepsis have been failedScientists identify mechanism that makes babies more likely than adults to die from sepsisFurther studies showed that the aggregated neutrophils inside pulmonary vessels exhibit a higher expression of the Mac-1 receptor (CD11b/CD18), which is a receptor involved in intercellular adhesion, compared to the neutrophils that normally circulate. Additionally, they confirmed that Mac-1 inhibitors can improve inhibited microcirculation, ameliorate hypoxia, while reducing pulmonary edema in the sepsis model.Their high-resolution 3D intravital microscope technology allows the real-time imaging of living cells inside the lungs. This work is expected to be used in research on various lung diseases, including sepsis.The research team’s pulmonary circulation imaging and precise analytical techniques will be used as the base technology for developing new diagnostic technologies, evaluating new therapeutic agents for various diseases related to microcirculation.Professor Kim said, “In the ALI model, the inhibition of pulmonary microcirculation occurs due to neutrophils. By controlling this effect and improving microcirculation, it is possible to eliminate hypoxia and pulmonary edema – a new, effective strategy for treating patients with sepsis.”Their 3D intravital microscope technology was commercialized through IVIM Technology, Inc., which is a faculty startup at KAIST. They released an all-in-one intravital microscope model called ‘IVM-CM’ and ‘IVM-C’. This next-generation imaging equipment for basic biomedical research on the complex pathophysiology of various human diseases will play a crucial role in the future global bio-health market.

Dermatologist shares five common sunscreen mistakes and offers tips to avoid them

first_img Ignoring the label- There are a variety of sunscreens on the market. To effectively protect yourself from the sun, the AAD recommends looking for sunscreens that are broad-spectrum, water-resistant and have an SPF of 30 or higher. Using too little- Most people only apply 25-50% of the recommended amount of sunscreen. However, to fully cover their body, most adults need about one ounce of sunscreen – or enough to fill a shot glass. Apply enough sunscreen to cover all skin that isn’t covered by clothing. Apply the sunscreen 15 minutes before going outdoors, and reapply every two hours while outdoors or after swimming or sweating. Applying only in sunny weather- Alarmingly, the AAD found that only about 20% of Americans use sunscreen on cloudy days. However, the sun emits harmful UV rays all year long. Even on cloudy days, up to 80% of UV rays can penetrate your skin. To protect your skin and reduce your risk of skin cancer, apply sunscreen every time you are outside, even on cloudy days. Using an old bottle-The FDA requires that all sunscreens retain their original strength for at least three years. Throw out your sunscreen if it’s expired or you’re unsure how long you’ve had it. In the future, if you buy a sunscreen that lacks an expiration date, write the purchase date directly on the bottle so that you know when to toss it out. Relying solely on sunscreen- Since no sunscreen can block 100% of the sun’s UV rays, it’s also important to seek shade and wear protective clothing, including a lightweight, long-sleeved shirt, pants, a wide-brimmed hat and sunglasses with UV protection.

Individuals who have been affected by skin cancer can also share their personal stories on SpotSkinCancer.org to provide support and inspiration for others fighting skin cancer and communicate the importance of skin cancer prevention and early detection. Reviewed by Kate Anderton, B.Sc. (Editor)May 14 2019Skin cancer is the most common cancer in the United States, affecting one in five Americans in their lifetime. Yet according to dermatologists from the American Academy of Dermatology, most cases of skin cancer can be prevented by protecting your skin from the sun’s harmful ultraviolet rays.The best way to do this, they say, is by seeking shade, wearing protective clothing and applying a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher. However, in a recent survey, the AAD found that not everyone is applying their sunscreen correctly -; leaving people vulnerable to dangerous ultraviolet radiation from the sun. Sunscreen is the most important skin care product you can use, as it helps prevent sunburn, skin cancer and premature skin aging, including wrinkles and age spots. However, to ensure the best protection for you and your family, it’s important to follow the manufacturer’s directions before using.”Tanya Kormeili, MD, FAAD To help the public protect their skin and reduce their risk of skin cancer, Dr. Kormeili shares five common sunscreen mistakes and how to avoid them: Source:American Academy of Dermatology Sunscreen is a vital tool in the fight against skin cancer, including melanoma, the deadliest form.

EKFs DiaSpect Tm hemoglobin analyzer used for anemia study in remote region

first_imgMay 17 2019EKF Diagnostics, the global in vitro diagnostics company, announces the highly successful use of its FDA cleared DiaSpect Tm (sold as Consult Hb in the USA) point-of-care hemoglobin analyzer to study iron-deficient anemia in a remote region of Ghana, West Africa. The Eleanor Mann School of Nursing at the University of Arkansas, USA, took 15 nursing students on a Study Abroad Program in Bolgatanga, Ghana in summer 2018. Working at small village clinics they established that anemia is very common among women of childbearing age, sometimes leading to blood transfusions, but more commonly, death. Therefore, in addition to measuring hemoglobin (Hb) using EKF’s fully portable hand-held analyzer and confirming the prevalence of anemia, the team also provided vital nutritional education. Given the success of this program, a further 15-strong team from the University will return in summer 2019, extending their anemia studies to include the elderly who are at high risk of death from anemia.In summer 2018, the nursing students centered Hb testing on women of child bearing age. After reading current research data on anemia in Ghana, they developed an anemia focused teaching program, providing education on the dietary importance of iron and protein. They also undertook a small research project on the women’s perceptions of anemia in women and children. This study concluded that it is imperative to understand the community before conducting public health initiatives to ensure that teachings are accurate and tailored to the culture and mindset of the target audience.Using the DiaSpect Tm for the study, a total of 176 Hb tests were undertaken with a 45% rate of tests below the normal values; these results supported the pre-study desk research and hypothesis that iron-rich and high protein foods need to be increased in the women’s diets.  The educational program focused on which local foods were iron-rich or high protein and why it is important to include them in the diets of new mothers, pregnant women and those of child bearing age.Leading the nursing team and study program, Carol Agana, University of Arkansas, explained why they chose to use EKF’s DiaSpect Tm in Ghana, “The point-of-care analyzer had to be unaffected by high ambient temperatures, as well as being easy-to-use and even easier to carry. Battery life was also important for working in remote areas, so when charged up it could last a very long time, which is great when electricity is either unavailable or intermittent.  Furthermore, having virtually instantaneous hemoglobin results meant that the participants didn’t have to wait or return for these. Also ideal was the fact that DiaSpect’s sampling cuvette requires such a tiny drop of blood from a standardized finger prick procedure.” Related StoriesEKF’s PCT LiquiColor assay receives FDA clearance and validation for use on Beckman AU analyzersEKF’s Quo-Lab POC HbA1c analyzer meets international quality targets for diabetes testingEKF signs private label distribution agreement with McKesson for new hemoglobin analyzerThe DiaSpect Tm provides users with precise hemoglobin measurements (CV within run ≤1%) within two seconds of its whole blood-filled microcuvette being inserted for analysis. Palm-sized, it is easily transportable, and ideal for use in any screening setting even in challenging climatic environments, as demonstrated by the Ghana-based study.Factory calibrated against the HiCN reference method in accordance with ICSH, DiaSpect is ‘always on’ and ready to use with no re-calibration or maintenance needed. Also ideal for point-of-care settings, the rechargeable internal battery (providing up to 40 days / 10,000 tests continuous use) means no power source is necessary for weeks at a time. Furthermore, its reagent-free microcuvettes have a shelf life of up to 2.5 years and can be used until the expiration date, even after opening the bag. They are also unaffected by humidity or temperature across a wide range, making it so well suited for hot and humid climates. EKF’s contribution to our project really helped to reinforce the education, and women were so impressed that they could actually get their blood checked immediately.  Even the local women working at the clinics asked to be tested too. Our nursing staff also found DiaSpect Tm great to work with as the self-training video was easy to follow, and it being hand-held and lightweight, it was very easily transported in its protective carry case. Overall, it was a very successful program and we look forward to returning this summer.”  Carol Agana, University of Arkansas Source:EKF Diagnosticslast_img read more

Engineers are developing a small cooled turbine to make drones more efficient

first_img Citation: Engineers are developing a small cooled turbine to make drones more efficient (2018, September 4) retrieved 17 July 2019 from https://phys.org/news/2018-09-small-cooled-turbine-drones-efficient.html Southwest Research Institute engineers are developing a cooled, radial gas turbine for a small generator that provides thousands of hours of electricity to an unmanned aerial vehicle (UAV), a significant improvement to current UAV turbines that only operate a few hundred hours before wearing out. This document is subject to copyright. 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. Turbines are rotary mechanical devices that, when combined with a generator, produce electrical power.”This turbine is part of a generator that’s similar to what the average person might use to generate electricity in their home when the power goes out,” said David Ransom of SwRI’s Mechanical Engineering Division. “The version we’re creating is more compact and efficient, tailored to the needs of a small, unmanned aircraft.”The problem with current small turbine models is that during the generator’s combustion process, the turbine is constantly bathed in high temperature gas that ultimately damages or destroys it.”The hotter the turbine gets, the better its performance,” Ransom said. “But these smaller turbines can’t survive the temperature, so we’ve designed one that has tiny airflow passages that cool the turbine without sacrificing the power of its performance. Normally with small turbines you have to make a choice between performance or reliability, but we’re making it possible to have both.”SwRI has worked with internal passages of high temperature turbines on large version used in power plants and passenger airplanes. To create the small, intricate design with internal air passages, engineers are using a new selective laser melting (SLM) machine, which builds metal parts layer by layer. The new SLM machine, which arrived at SwRI in December 2017, sets itself apart from other 3-D printers in that it’s built to craft layered and highly detailed metal parts rather than plastic ones.To leverage the capability of the new SLM machine, the SwRI Advisory Committee for Research launched the Metals Additive Kickoff Emphasizing Research Synergies (MAKERS) program, an internal research and development effort. MAKERS is designed to encourage collaboration between SwRI researchers on projects utilizing the revolutionary new technology. The new turbine is one of the first products to result from the MAKERS program. MAKERS and other internal research programs invest in innovative technologies that ultimately benefit client-sponsored programs.”Generators that provide power to us and to big aircraft already have cooled turbines, whereas a generator of this size for a small craft does not,” Ransom said. “It’s an exciting engineering challenge, and having the ability to print parts with the SLM machine is a real advantage.” Explore further Provided by Southwest Research Institute New blades and generators for more efficient small wind turbineslast_img read more

22 GMs to elevate as executive directors at PSU banks

first_imgrecommendation COMMENT Banks Board Bureau (BBB), the advisory body formed by the government for selection of candidates for top level board appointment, has recommended 22 general managers to be elevated as executive directors at the various public sector banks. This is the first major exercise undertaken by the BBB, headed by newly appointed chairman B P Sharma, former Secretary, Department of Personnel and Training. Sharma was appointed head of the panel in April after completion of two-year term of former CAG Vinod Rai. The chairman and members of the panel have recommended to the Government of India 22 general managers for being appointed as executive directors in public sector banks (PSBs), BBB said in a statement. The panel has recommended general managers Manas Ranjan Biswal, Gopal Gusain, Vivek Jha, Alok Srivastava, Hemant Kumar Tamta, Ajit Kumar Das, Agyey Kumar Azad, Dinesh Kumar Garg, Sanjay Aggarwal and Shanti Lal Jain for appointment as EDs. Besides, Vijay Dube, Ajay K Khurana, A Manimekhalai, Vikramaditya Singh Khichi, Usha Ravi, P R Rajagopal, Shenoy Vishwanath Vittal, Atul Kumar, K Srinivasa Rao, Sanjay Kumar, K Ramchandran and Ajay Vyas too would be elevated.“These recommendations are based on interactions held by the Banks Board Bureau with eligible candidates from PSBs towards appointment against vacancies in PSBs for the period 2018-19,” it said. The Appointments Committee of Cabinet headed by Prime Minister Narendra Modi will take the final decision in this regard. There are already some vacancies at executive director level and some would be created during the course of the year.
