Arctic and Antarctic polar winter NOx and energetic particle precipitation in 2002-2006

first_imgWe report GOMOS nighttime observations of middle atmosphere NO2 and O-3 profiles during eight recent polar winters in the Arctic and Antarctic. The NO2 measurements are used to study the effects of energetic particle precipitation and further downward transport of polar NOx. During seven of the eight observed winters NOx enhancements occur in good correlation with levels of enhanced high-energy particle precipitation and/or geomagnetic activity as indicated by the Ap index. We find a nearly linear relationship between the average winter time Ap index and upper stratospheric polar winter NO2 column density in both hemispheres. In the Arctic winter 2005 – 2006 the NOx enhancement is higher than expected from the geomagnetic conditions, indicating the importance of changing meteorological conditions.last_img read more

Bus safety tips

first_imgBy Faith PeppersUniversity of GeorgiaTo be certain children have a safe trip to school each day, trythese safety tips from the National Highway Traffic SafetyAdministration:* Make sure children get to the stop on time, wait far away fromthe road and avoid rough play.* Teach your child to ask the driver for help if he dropssomething near the bus. If a child stoops to pick up something,the driver can’t see him. Then he could be hit by the bus. A bookbag or backpack helps keep loose items together.* Make sure clothing has no loose drawstrings and backpack strapsare short, so they don’t get caught in the handrail or bus door.* If you think a bus stop is in a dangerous place, talk with yourschool office or transportation director about changing thelocation. Teach your child to get on and off the bus safely:1. When getting on, stay away from the danger zone near the busand wait for the driver’s signal. Board the bus single file.2. When getting off, look before stepping off the bus to be sureno cars are passing on the shoulder. Move away from the bus.3. Before crossing the street, take five “giant steps” out fromthe front of the bus, or until the child can see the driver’sface. Wait for the driver to signal that it’s safe to cross.4. Look left-right-left when coming to the edge of the bus tomake sure traffic is stopped. Continue to watch for traffic whencrossing.Other motorists pose the greatest threat to children traveling toschool. Most children are injured at bus stops by cars illegallypassing the bus.Drivers coming to a school bus from either direction must stopwhen the bus displays flashing red warning lights and extends thestop-signal arm. These signals show that children are getting onor off the school bus.Don’t pass until the flashing red lights and signals are turnedoff.Drivers traveling in the same direction as the bus are alwaysrequired to stop. In some states, but not in Georgia, driversmoving in the opposite direction on a divided roadway are alsorequired to stop.Never pass on the right side of the bus, where children enter orexit. This is illegal and can have tragic results.For more information, call the NHTSA Auto Safety Hotline(1-888-DASH-2-DOT) or visit the NHTSA Web site( read more

How Could Polar Dinosaurs Survive Freezing, Darkness?

first_imgNational Geographic News has a report about a new exhibit of dinosaur fossils that have been found in the northern and southern polar regions.  These unusual creatures had to survive not only the cold, but also, due to the effects of orbital mechanics, six months of darkness each year.  Intrepid explorers in south Australia, northern Canada, Patagonia, Alaska and Antarctica have braved the elements since the 1980s to find dinosaur bones in the extreme polar regions.  Their discoveries have changed our conceptions of dinosaur metabolism and the ecosystems in which they lived.  Polar dinosaurs include:Hypsolophodontids: “small, speedy, plant-eating dinosaurs that ran on two feet.”  They had large eyes, apparently adapted to low light levels, and bones that grew throughout the year, suggesting they were warm blooded.  The plants on which they fed apparently did not drop their leaves during the winter.A horned dinosaur named Serendipaceratops arthurcclarkei (no kidding) must have looked like something out of a sci-fi movie.  NG claims this is “one of the oldest horned, or frilled, dinosaurs known, which suggests that horned dinosaurs may have originated in the southern polar region.”A sauropod, possibly the largest found in Antarctica, is being analyzed.  It was found at 13,000 feet elevation.An allosaurus-like meat eater named Cryolophosaurus ellioti was 22 feet long.The exhibit at Seattle’s Burke Museum is called “Dinosaur of Darkness.”Throughout the world there are mysteries.  Fossils give silent evidence of a very different world in the past; a world with polar regions that must have supported lush plant life and rich ecologies of diverse plants and animals larger than those living today.  Large redwood stumps have also been found in the Arctic circle (see 03/22/2002 headline), and there are the legendary frozen mammoths of Siberia.    This article suggests that “the climate was warmer then than it is now,” but puzzles over the fact that these dinosaurs must have “endured months of darkness and temperatures that plunged below freezing.”  For plants to have supported herbivores and carnivores of this size near the poles, it would seem there must have been atmospheric conditions that evened out the lighting and temperature.    As for horned dinosaurs originating near the south pole, we laugh, ha ha, at this funny joke.(Visited 38 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Canada to share GIS know-how

first_img3 November 2005Canada is willing to share its Geographic Information System (GIS) expertise with South Africa.Canadian high commissioner Sandelle Scrimshaw told delegates from both countries at a GIS seminar in Pretoria on Wednesday that her country had amassed skills in research, development and technology and was willing to share with the rest of the continent.“We are keen to share these with South Africa, Africa and the rest of the world,” she said, adding that Canada viewed South Africa as a strategic partner for science and technology on the continent.“I know that our companies are also willing to collaborate with their African counterparts,” she said.Strategic partnershipDelegates met at the Innovation Hub in Pretoria to explore potential areas of co-operation in science and technology between the two countries.Earth observation and geosciences constitute strategic priorities for South Africa and play a crucial role in informing policy and decision making.GIS is a system that manages, analyses, and disseminates geographic knowledge.Throughout AfricaCanadian Director for Natural Resources Martin Aube said they had already embarked on earth science activities in other African countries such as Burkina Faso, Gabon, Ghana, Mali, Morocco, Mozambique and Senegal.He said his country was also supporting African countries to address environmental challenges such as natural resource management and environmental impact assessment.General Director for the Canadian Space Agency Paul Engel said they used space to monitor areas at risk for malaria and other diseases.Space policySpace Affairs Advisor for the Department of Trade and Industry Mothibi Ramusi said South Africa was currently developing a space policy.He said there is a satellite centre at the Hartebeespoort that could help the country in terms of disaster management.Ramusi said Africa faced challenges of poverty and climate change and that the information and analysis GIS provided could help the continent to deal with these issues.He said that access to satellite data at an affordable rate was a problem. “Other challenges [are getting] operating licence and hardware costs as well as availability of basic information such as statistics,” he said.Monitoring toolHowever, Ramusi acknowledged that earth observation had societal benefits in terms of monitoring service delivery, especially in South Africa.“In South Africa, government is embarking on service delivery programmes so earth observation can be used as a monitoring tool in this regard,” he said.Ramusi recommended that the co-operation between South Africa and Canada focus on exchange programmes of domain experts and well as exposure to technological development relating to GIS.Source: BuaNewslast_img read more

Vodacom’s solar-powered cellphone

first_img5 October 2010In a bid to exploit South Africa’s abundant sunshine and reduce reliance on mains electricity, Vodacom has launched a low-cost solar-powered mobile phone with the unique ability to charge on the go – even when it’s not in direct sunlight.Developed by Vodafone, the VF 247 has the unique ability to charge on the go, enabling people to benefit from mobile communications even in areas where electricity is scarce.“Cellphones are the primary means of communication for millions of South Africans, and thanks to our association with Vodafone we’re able to supply this new solar-powered handset, which makes it as easy and practical as possible for people to connect,” Vodacom South Africa MD Shameel Joosub said in a statement last week.Integrated solar panelThe VF 247 is designed with an integrated solar panel, saving users both time and money. The special built-in Sun Boost software ensures that the phone charges even when it’s not in direct sunlight.Charging the phone in sunlight for an hour or two every day should be enough to cover the power needs for average users, but if the battery runs low the phone can be topped up with a traditional mains power charger.“In many communities, electricity supplies are intermittent or non-existent, but with this new handset, people won’t have to worry about when they are next going to be able to charge the battery,” said Joosub.“It’s so simple and obvious, but the combination of solar power and a low-cost handset will hopefully make a big difference.”Basic voice and text featuresThe handset has been fitted with a high-temperature battery that can safely withstand increased operational temperatures. To prevent it from failure, an additional temperature protection is also embedded which will switch off any charging should the battery exceed the safe temperature.The VF 247 is an easy-to-use device that has all the basic voice and text features along with FM radio, torch and a colour display.SAinfo reporterWould you like to use this article in your publication or on your website?

‘Politicians, journalists, editors – we are all custodians of democracy’ – Ramaphosa

first_imgRead the full text of Deputy President Cyril Ramaphosa’s opening remarks at the 2015 indaba between the government and the South African National Editors’ Forum in Pretoria on Saturday 21 November.Deputy President Cyril Ramaphosa with members of the South African National Editors’ Forum at Sefako Makgatho Presidential Guest House in Pretoria on Saturday 21 November. (Image: The Presidency)Colleagues and compatriots, thank you all for being here today.We are hopeful that this engagement – which is long overdue – will enable a frank and robust discussion on the challenges and opportunities that shape our country and drive our public discourse.During these engagements, we are permitted to ask penetrating and difficult questions of ourselves and each other.As government, we strive to establish constructive partnerships with stakeholders across all sectors of our society.Such partnerships underpinned by dialogue and the joint actions that result from them, help us to move forward.These partnerships help to ensure that our nation is motivated by shared values, a common understanding of the challenges we face and a collective appreciation of the transformation that is underway in our society.As members of the executive and as representatives of the media, we each have assigned roles in society.We each have important functions to perform and are, in different ways, accountable to the South African public for the way we perform these functions.We therefore share a common responsibility.We are, all of us, custodians of the promise of 1994.We are all custodians of the aspirations of the millions of South Africans who have struggled, suffered and sacrificed to be free.Each of us – politicians, journalists, editors – are custodians of our democracy, of development, of justice and equality.We all therefore have a profound and abiding interest in the progress we are making towards the realisation of that promise of 1994.We are and should be encouraged by every accomplishment.We are and should be concerned about every setback.I hope that in our discussions today we can remain mindful of this shared responsibility.Colleagues,The relationship between government and the media in any democracy is underpinned and marked by healthy tensions.Since we first met in this forum many years ago our relationship has improved and become more constructive.These engagements, I am told, have always been forthright and robust.From government’s perspective, our approach to our engagement is grounded in our commitment to a free and thriving media.We hold the view that the media is critical in informing citizens about the work of government and educating them about their rights and responsibilities.To be successful as a country and nurture a functioning democracy we need to partner with the Fourth Estate so that it can empower citizens.South Africans expect the media to scrutinise the actions and policies of government.They expect to know what government is doing, and what government is not doing.But more than that, they want to be part of that engagement.With the emergence of new media platforms, citizens are increasingly able to shape public discourse. They are also able to be active public discourse participants and indeed activists arising from these new media platforms.They are able to ask difficult questions. They are able to offer solutions and actively promote their interests.Even in the age of citizen journalism and social media, the formal news media remains an institution entrusted with the task of informing, explaining, interpreting and making sense of the complexity of current affairs and modern life.The formal traditional media continues to enjoy access to our legislatures, various institutions, courtrooms and boardrooms to report and offer commentary.It is able to engage with institutions – both public and private – in a direct and meaningful way.As government, we appreciate the role that the formal news media plays and have been working to improve our ability to facilitate that role.Early in the term of this administration, President Jacob Zuma established an Inter-Ministerial Committee on Information and Publicity, chaired by Minister Jeff Radebe.This committee seeks to improve government’s communications operations and to build stronger relations with the media.The Presidency will soon launch the Presidential Media and Communication Working Group, which will bring government into contact with media proprietors and sectoral experts.This will enable government to develop an understanding of developments and challenges in this important economic sector.We have also undertaken to establish a Presidential Press Corps, which will comprise journalists who cover the Presidency.This is intended to improve the quality and depth of the Presidency’s and therefore government’s interaction with the media.It will also create a formal channel of communication between the Presidency and journalists covering the institution.We see an important role for Sanef in the implementation of this new arrangement.We hope that this engagement will identify other areas where we can improve engagement and cooperation.Colleagues,The free flow of information among all South Africans is vital to securing the social cohesion, collective focus and coherent action needed to advance our national developmental objectives.Our engagement today should therefore explore how we can use our respective platforms to realise the promise of 1994.This government has a mandate to address poverty, unemployment and inequality.The government’s policies carry the overwhelming endorsement of the electorate.In successive elections, they have voted for development, transformation and redress.They have endorsed the National Development Plan and look to government to lead in its implementation.They have correctly identified economic transformation as the central task of the moment.This is a task that falls to all of us, for it is through the radical transformation of the economy that we will build a united, prosperous nation.By creating jobs, we will improve livelihoods.By developing skills, we will grow the economy.By ending poverty, we will reduce inequality and build social cohesion.We need a national effort to grow an inclusive economy.An effort in which all stakeholders will revisit longstanding attitudes and assumptions about each other, so that our factories, office blocks, spaza shops, stock market and home offices can become centres of growth and transformation.We undertake this effort under challenging domestic and international circumstances.Growth is faltering amid a slowdown in global demand and a dramatic decline in commodity prices.The systemic challenges in our economy – principally, the skills deficit and high unemployment rate – are aggravated by energy constraints, low levels of domestic savings, and increased pressure on public finances.Government is investing significantly in economic infrastructure, expanding energy and water supply, improving transport and logistics capabilities, and installing broadband across the country.Even in difficult economic conditions, we are sustaining our investment in schools, colleges, universities, hospitals and clinics.We are sustaining spending on social grants, housing, textbooks, antiretrovirals and the many other social interventions needed to tackle poverty and promote development.We are committed to act decisively against those who abuse or neglect public resources as we tackle poor administration and inefficiencyGovernment is constantly facilitating interaction between South African businesses and their counterparts abroad.Our government-to-government relations are these days invariably accompanied by business-to-business engagement.We do this because we want South African businesses to succeed at home and abroad, and we want to ensure that South Africans enjoy the practical benefits of our extensive interaction with the world.Colleagues,Social partnership is critical to the success of these endeavours.No government anywhere in the world could achieve these goals alone.We therefore continue to promote cooperation and collaboration, whether it be in the higher education space, in health care or in the labour market.As an example, we are currently engaged in a dialogue with our social partners in Nedlac on the introduction of a national minimum wage.These discussions are at an advanced stage, with agreement having been reached on key principles and mechanisms.As this process nears its conclusion, we are having to confront challenging and difficult questions about the level at which the minimum wage should be set and the process by which that determination should be made.In many ways, we are entering a phase of engagement not unlike the negotiations that led to the adoption of our democratic Constitution.There are still areas of difference.There are still competing interests that need to be accommodated.And yet, there is a shared determination to find a solution that advances our efforts to both grow the economy and improve the lives of workers which will lead to lower levels of inequality.There is a commitment to find common ground.By crafting a meaningful a national minimum wage we have an opportunity to address income inequality. We also have an opportunity to stabilise our labour environment, and, above all, to advance our national interest.There are many other areas where we are working together with our social partners to address common challenges.We look to the media not only to report on these efforts, but to engage with them, to critique them, to analyse them, even to embrace them.We look to the media to be a critical part of transformation and development.We look to the media as committed and meaningful social partners.Together, we are custodians of democracy, of development, of justice and equality.Together, we are the custodians of the promise of freedom and transformation.last_img read more

Without a nation there is nothing to brand

first_imgNation branding challenges and successes faced by Eastern European countries such as Ukraine, Bulgaria and Kosovo, in the wake of political and social change in the region since 1989, were held up as lessons in nation branding.Professor Nadia Kaneva offered the analysis in a presentation titled “The branded national imagination and its limits: Insights from the post-socialist experience” given at a Brand South Africa Competitiveness Forum for South African academia. Held at the University of Pretoria, Tshwane, on 5 October 2016, the forum aimed at in-depth analysis of global and domestic issues influencing the reputation and competitiveness of the nation’s brand.“As communism was ending, the Romanian flag allowed for a discourse around the future of the Nation” says Dr. Nadia Kaneva @Brand_SA forum— Guido van Garderen (@GuidovGarderen) October 5, 2016Presenting at the event were key academics in the fields of business, humanities and political science, from a host of South African universities and tertiary institutions.The goal of the dialogue is to compile all presentations and contributions into a peer-reviewed journal, with a view to positioning South Africa as a thought leader in nation branding. Key to the success of that journal will be the keynote contribution from Kaneva.Bulgarian-born Kaneva is an associate professor in the University of Denver’s media, film and journalism faculty. She is a globally respected and widely published researcher who uses critical sociology and media studies to dissect the commercialisation of politics and culture in Eastern Europe through nation branding and reputation-building.Kaneva’s ultimate conclusion – that in order to be more effective, an imagined nation brand should align closer to and more realistically to the changes in the nation and its people – was honed through extensive research on radical changes in Romania after the fall of communism, post-conflict Kosovo during the 2000s and the relationship between Ukraine and Russia as recently as three years ago.The lessons learnt in the research can be just as easily applied to any nation brand, especially for emerging economies like South Africa, she says.In introducing Kaneva, University of Pretoria deputy dean of humanities Professor Maxi Schoeman highlighted the importance of getting an outsider view on building South Africa’s brand internationally, someone objective enough to weigh up the differences and similarities between the country and nations with similar histories.The science and application of nation branding was now very much part of mainstream academia and an essential tool for governance, Kaneva said at the start of her presentation. As a legitimate interdisciplinary field, the study of nation branding included elements of media and marketing ideas, anthropological study, business theory and sociology.Yet, Kaneva argued, developing and managing a national brand and reputation would always be a highly political and therefore delicate process, the success of which did not always lie in the area of savvy marketing or critical theory.This was evident in post-socialist Eastern Europe countries experiencing the swift changes of political and economic experiments, Kaneva said.Extensive global multichannel marketing campaigns by Romania and Kosovo highlighted each country’s promise in its people and economics in a vastly depoliticised way, focusing on things such as tourism and investment and replacing a more realistic national identity with something more market-oriented, in other words, what “the outside world wanted to see”.In 2009, two years after gaining independence, Kosovo’s first attempt at marketing the country to the outside world was in the form of a television commercial, The Young Europeans. While carrying a positive message of reconciliation and cultural tolerance as well as an eagerness to partake economically in the European Union, it told little about the country and its people to outsiders (investors, tourists) that would differentiate it from any other European nation.While initially successful, there was a negative reaction from citizens, who felt misrepresented by this imagined nation brand. As Kaneva says, a rejection of idealised, imagined branding is ultimately counter-productive to what a country brand really wants to achieve.Watch The Young Europeans:At the crux of the argument, Kaneva says, is honesty with the nation brand, creating an identity that can actually be recognised by the people it is supposed to be representing.Offering solutions to link the imagined nation brand closer to reality, Kaneva highlighted the following:Recognise that nation branding has a political element and embrace it, with all its shortcomings and diversities.Invest in programmes and policy that encourages and grows both citizen engagement and development in the nation and its brand: let people inform the national message.Look beyond the data of perception ratings to formulate effective nation brand evaluation and measurement: outside views, particularly those formulated with data, are important, but other research models are necessary to get the complete picture of a nation.Diminish the focus and use of transnational mass media nation brand advertising; look to niche marketing opportunities for creating a truer, most consistent national image and reputation.Concluding her presentation, Kaneva said that reconstructing and refreshing national identities, particularly for nations with a history of significant political and societal transformation, should always consider the transformations of the people it represented, adding that, “without a nation there will be nothing to brand”.Download full reporterWould you like to use this article in your publication or on your website?

Barcelona forward Ousmane Dembele out for two weeks due to ankle sprain

first_imgBarcelona’s French international forward Ousmane Dembele will be out for two weeks after spraining his ankle in Sunday’s 3-1 victory over Leganes, the Spanish champions said on Monday.The news comes as a blow for the 21-year-old, who opened the scoring for the La Liga leaders and has impressed in recent weeks, netting six times in his last 10 outings.The injury means he is likely to miss both legs of their Copa del Rey quarter-final with Sevilla, and Sunday’s Catalan derby at Girona.It is also possible that he could be sidelined for the visit of Valencia at the beginning of February, although he should be fit for Barca’s Champions League last-16 meeting with Olympique Lyonnais in February.Fellow big-money arrival Philippe Coutinho will be expected to fill the void created by Dembele’s absence, with the Brazilian struggling for game time since his 160 million Euros ($181.87 million) move from Liverpool 12 months ago.last_img read more
