Helen Bennion first came to UCL in 1985 to study Geography where she obtained a first class honours degree and some years later a PhD, which examined sediment records of eutrophic ponds in south-east England. She was awarded a post-doctoral Royal Society Research Fellowship and spent a year at the Institute of Limnology, Mondsee in Austria. She returned to the Department of Geography at UCL in 1995 to take up a post as Research Fellow with the Environmental Change Research Centre (ECRC) and was promoted to Senior Research Fellow in 2001, then to Principal Research Associate in 2009, to Reader in Environmental Change in 2011, and most recently to Professor in Environmental Change in 2017.
Her research interests are in aquatic ecology and palaeoecology with a focus on freshwater diatoms. Over the last twenty-five years she has undertaken numerous national and international research projects examining the impacts of eutrophication on standing fresh waters over a range of time scales and employing lake sediment records to assess environmental change, reference conditions and restoration targets. Since 1996, she has been involved in EU collaborative research on five large multi-partner projects (BIOMASS, EDDI, Euro-LIMPACS, WISER and REFRESH), the most recent of which examined climate-nutrient interactions in aquatic ecosystems. She is currently working on a large NERC HIghlight Topic project 'Hydroscape' that explores how stressors and connectivity interact to influence biodiversity and ecosystem function in freshwaters across Britain.
Helen is interested in the application of science to lake management and conservation, particularly the EU Water Framework Directive. She was an invited member of the UK Lakes Task Team and UK Eutrophication Forum which advised on strategic research and development, and fed into environmental policy. Until 2018, much of Helen's applied research was carried out via ENSIS Ltd, the consultancy affiliated to the ECRC, of which she was appointed Director in 2006. ENSIS closed for business in March 2018.
Her publications include around 70 academic articles and over 80 research reports and she is a peer reviewer for numerous international scientific journals and funding bodies. She has supervised more than 20 Masters and PhD students and teaches on undergraduate and masters courses including topics of lake eutrophication, palaeoecological methods, water policy, lake management and conservation.

Project manager of over 80 projects funded by bodies such as the Environment Agency, English Nature, Scottish Natural Heritage, Countryside Council for Wales, Scotland and Northern Ireland Forum for Environmental Research, and the Irish Environment Protection Agency (1995-present). These cover research topics such as nutrient reconstructions of standing waters, lake classification and monitoring, water quality and sediment assessment, lake database and risk protocol development, and restoration feasibility studies (see 'Impact' section for details).
Helen is interested in the application of limnology and palaeolimnology to lake management and conservation, particularly the EU Water Framework Directive. The desire to contribute to the management of the aquatic environment underpins all of her research.
Helen has worked closely with government and conservation agencies to define ecological and chemical reference conditions for lakes in Europe and in China. For example, she has been centrally involved in advising the Environment Agency, Scottish Environment Protection Agency, Natural England, Countryside Council for Wales (now Natural Resources Wales) and Scottish Natural Heritage on reference conditions for UK lakes including development of an ecological classification tool using diatoms (DARLEQ). This was facilitated by her invited membership of the UK Lakes Task Team (2005-2009) and provided the evidence base to inform UK Government response to the EU Water Framework Directive. She co-edited a special issue of Journal of Paleolimnology (vol 45, 2011) on "Reference states and lake restoration". Her applied diatom work has helped to inform restoration strategies of >50 lakes suffering from nutrient enrichment.
She was an invited guest on BBC Radio 4s Material World programme in Sept 2005 to speak about diatoms as indicators of environmental change.
She has given talks to local interest groups (e.g. Morvern Historical Society) and regularly presents her research outputs at meetings attended by a range of stakeholders (e.g. Llangorse Lake and Llyn Tegid symposia and the Loweswater Care Project).
She is a member of the Environment Agency (EA) expert panel on diatom quality assurance and hosts regular training workshops for EA staff.
From 2005-2018 Helen was a director of ENSIS Ltd, an environmental consultancy within the Geography Department dedicated to supporting the research of the Environmental Change Research Centre. On behalf of ENSIS Ltd, she co-ordinated applied work on lowland and shallow lake systems.
In the last 20 years she has been the project manager of over 80 projects which have helped to inform lake conservation and management. Projects include:·
Identification of reference lakes and evaluation of palaeoecological approaches to define reference conditions for UK (England, Wales, Scotland & Northern Ireland) ecotypes (2002-2004), Scotland and Northern Ireland Forum for Environmental Research.
Development of an interactive CD-ROM for the identification of freshwater diatoms of the British Isles (2002-2004), Environment Agency.

Helen has supervised several PhD students who have worked with CASE partners to deliver projects with real impact:
Emily Smith (2014-2019) worked with the Angling Trust to explore the role of angling as a pathway by which invasive aquatic species are brought to the UK. The findings from the PhD have been used to inform invasive non-native species (INNS) policy, in particular the development of an Angling Pathway Action Plan for Great Britain, improved communication of the 'Check, Clean, Dry (CCD)' campaign and to encourage the adoption of CCD in Western Europe. Emily also gave oral evidence at an Environmental Audit Committee enquiry into INNS in July 2019, using her PhD findings and work with the Angling Trust to articulate the environmental and economic threats of INNS and the importance of biosecurity in reducing the risk of INNS spread.

We would like to thank you for coming to our website in search for "Blackcoin Wallet 10gb" online. Mining cryptocurrencies is how new coins are placed into circulation. Because there's no government control and crypto coins are digital, they cannot be printed or minted to produce more. The mining process is what makes more of the coin. It may be useful to consider the mining as joining a lottery group, the pros and cons are precisely the same. Mining crypto coins means you'll get to keep the total rewards of your efforts, but this reduces your chances of being successful. Instead, joining a pool means that, overall, members will have a higher chance of solving a block, but the benefit will be split between all members of the pool, according to the number of "shares" won.
If you are considering going it alone, it's worth noting that the software settings for solo mining can be more complicated than with a swimming pool, and beginners would be probably better take the latter route. This option also creates a secure stream of earnings, even if each payment is small compared to completely block the benefit. Here is the trendiest thing about cryptocurrencies; they do not physically exist anywhere, not even on a hard drive. When you take a look at a specific address for a wallet containing a cryptocurrency, there is no digital information held in it, like in precisely the same way a bank could hold dollars in a bank account. It's nothing more than a representation of value, but there is absolutely no genuine tangible kind of that value. Cryptocurrency wallets may not be seized or immobilized or audited by the banks and the law. They don't have spending limits and withdrawal restrictions imposed on them. No one but the person who owns the crypto wallet can determine how their riches will be managed.
Blackcoin Wallet 10gb: Put CryptoCoin in YoWallet!
Entrepreneurs in the cryptocurrency movement may be wise to explore possibilities for making gigantic ammonts of cash with various forms of online marketing.There could be a rich reward for anyone daring enough to endure the cryptocurrency markets.Bitcoin structure provides an instructive example of how one might make lots of money in the cryptocurrency markets. Bitcoin is an incredible intellectual and technical accomplishment, and it has generated an avalanche of editorial coverage and venture capital investment opportunities. But not many people understand that and lose out on quite profitable business models made available as a result of growing use of blockchain technology. The trades of Bitcoins are recorded in ledgers which are referred to as Blockchains. The ledgers use extremely sophisticated technology about them to work. The notion is very simple than you think. The Blockchain enables two parties to create a smart contract. The contract can be created between two firms in a platform understood It is certainly possible, but it must be able to recognize opportunities irrespective of market behavior. The market moves in relation to price BTC … So even supposing it's in a BTC trend down can make money by purchasing the altcoins which are altcoin oversold trading ratios-BTC. Sure, your purchasing power in DOLLARS may be lower, but as long as your purchasing power in BTC is still growing you will be ok. You are able to run a search on the web. First learn, then models, indicators and most importantly practice looking at old charts and pick out trends. When you learn to keep a trading diary screenshots and your comment/forecast. Precisely what is the best way to get confident with charts IMHO. Oh certainly, and don't fool yourself into thinking that you get the uptrend will never decrease! Always will go down! Viewers incremental profits are more reliable and profitable (most times) It should be hard to get more small gains (~ 10%) throughout the day. Study the way to read these Candlestick charts! And I found these two rules to be true: having small gains is more profitable than attempting to fight up to the pinnacle. Most day traders follow Candlestick, so it's better to look at publications than wait for order confirmation when you believe the price is going down. Second, there is more unpredictability and reward in monies that have not made it to the profitability of websites like Coinwarz. When searching forBlackcoin Wallet 10gb, there are many things to consider.

Despite the criticism and skepticism, a cryptocurrency coin may be better suited for some uses than others. Fiscal privacy, for instance, is amazing for political activists, but more problematic as it pertains to political campaign financing. We need a stable cryptocurrency for use in commerce; if you're living pay check to pay check, it would take place within your riches, with the rest reserved for other currencies. Ethereum is an incredible cryptocurrency platform, however, if growth is too fast, there may be some issues. If the platform is adopted quickly, Ethereum requests could increase drastically, and at a rate that exceeds the rate with which the miners can create new coins. Under a situation like this, the entire stage of Ethereum could become destabilized because of the raising costs of running distributed programs. In turn, this could dampen interest Ethereum stage and ether. Uncertainty of demand for ether can lead to a negative change in the economical parameters of an Ethereum based company that may result in company being unable to continue to operate or to discontinue operation. You've probably heard this often where you often distribute the good word about crypto. "It's not unpredictable? What happens if the value failures? " sofar, several POS systems presents free conversion of fiat, improving some worry, but before volatility cryptocurrencies is resolved, most people will undoubtedly be resistant to put up any. We have to discover a way to fight the volatility that's inherent in cryptocurrencies. The physical Internet backbone that carries information between different nodes of the network has become the work of several firms called Internet service providers (ISPs), which includes firms that provide long-distance pipelines, occasionally at the international level, regional local pipe, which finally joins in households and businesses. The physical connection to the Internet can only happen through one of these ISPs, players like level 3, Cogent, and IBM AT&T. Each ISP runs its own network. Internet service providers Exchange IXPs, owned or private businesses, and occasionally by Governments, make for each of these networks to be interconnected or to move messages across the network. Many ISPs have arrangements with providers of physical Internet backbone providers to offer Internet service over their networks for "last mile"-consumers and businesses who want to get Internet connectivity. Internet protocols, followed by everyone in the network causes it to be possible for the information to flow without interruption, in the right spot at the right time.
While none of these organizations "possesses" the Internet collectively these businesses decide how it works, and recognized rules and standards that everyone stays. Contracts and legal framework that underlies all that is occurring to ascertain how things work and what happens if something goes wrong. To get a domain name, for instance, one needs permission from a Registrar, which includes a contract with ICANN. To connect to the Internet, your ISP must be physical contracts with providers of Internet backbone services, and suppliers have contracts with IXPs from the Internet backbone to connect to and with her. Concern over security dilemmas? A working group is formed to focus on the problem and the solution developed and deployed is in the interest of all parties. If the Internet is down, you have someone to phone to get it mended. If the difficulty is from your ISP, they in turn have contracts in place and service level agreements, which govern the manner in which these problems are resolved.
The benefit of cryptocurrency is that it uses blockchain technology. The network of nodes the make up the blockchain is not regulated by any focused firm. No one can tell the miners to update, speed up, slow down, stop or do anything. And that is something that as a committed promoter badge of honour, and is identical to the way the Internet operates. But as you understand now, public Internet governance, normalities and rules that govern how it works current inherent difficulties to the consumer. Blockchain technology has none of that. If you are in search for Blackcoin Wallet 10gb, look no further than Bitcoin.
Bitcoin is the main cryptocurrency of the web: a digital money standard by which all other coins are compared to. Cryptocurrencies are distributed, world-wide, and decentralized. Unlike traditional fiat currencies, there is no authorities, banks, or any other regulatory agencies. As such, it really is more resistant to wild inflation and tainted banks. The advantages of using cryptocurrencies as your method of transacting money online outweigh the security and privacy risks. Security and seclusion can readily be realized by simply being clever, and following some basic guidelines. You wouldn't put your entire bank ledger online for the word to see, but my nature, your cryptocurrency ledger is publicized. This can be fixed by removing any identity of ownership from your wallets and thereby keeping you anonymous. Since one of the oldest forms of making money is in money lending, it is a fact you could do this with cryptocurrency. Most of the giving sites currently focus on Bitcoin, many of these sites you're required fill in a captcha after a specific time frame and are rewarded with a small quantity of coins for seeing them. You are able to see the www.cryptofunds.co web site to locate some lists of of these sites to tap into the money of your choice. Unlike forex, stocks and options, etc., altcoin marketplaces have quite different dynamics. New ones are constantly popping up which means they do not have a lot of market data and historical perspective for you to backtest against. Most altcoins have quite poor liquidity as well and it is hard to produce a reasonable investment strategy. Anyone can become a Bitcoin miner running applications with specialized hardware. Mining applications listen for broadcast trades on the peer-to-peer network and perform the appropriate jobs to process and support these trades. Bitcoin miners do this because they can earn transaction fees paid by users for quicker transaction processing, and new bitcoins in existence are under denominated formulas.

We are committed to creating
a vibrant, diverse, powerful community of womxn who are not afraid to speak our minds, take risks, elevate each other, create meaningful change, and live in pursuit of our desires.
The Perlene was born out of a desire for founder Kiki Littlestar to be surrounded by a community of powerful and open-hearted womxn who wanted to do business- and life- differently. She named the business after her maternal grandmother, a nod to the belief that none of us get where we are going all on our own.
On her 32nd birthday, Kiki declares that in 9 months she will create something that brings ambitious womxn together. She did not know what it would become. She recruits two friends, takes $10,000 from her savings, and gets to work.
A lease was signed on a little two-story building in Southeast Portland, with lots of windows and potential. Later that week, the Presidential election would prove that we need this space, and each other, more than ever.
The little building is transformed into a feminine fortress, and The Perlene opens her doors for our grand opening party. Over the next 3 years, more than 200 womxn add their power to the community, and we outgrow our space.
The Perlene moves to her custom-built clubhouse in the Fair-Haired Dumbbell, adding a wine bar, beauty lounge with sauna and shower, stage, board room, and views of downtown Portland. It is an exquisite home worthy of holding this community and our future.

Humans > Obituary
Ric Ocasek officially made driving a lover's obligation
The frontman of The Cars is gone, and we salute him
V Vernon B. Sarne
Ric Ocasek wrote The Cars' 1984 hit song 'Drive'. SCREENSHOT FROM RHINO
If you grew up in the 1980s, you should be very familiar with rock legend Ric Ocasek, who belted out such classics as "My Best Friend's Girl," "Shake It Up" and "Tonight She Comes" as the frontman of a band, and sang "Emotion in Motion" as a solo artist.
According to reports, Ocasek was found dead in his New York townhouse in the afternoon of September 15 (US time). He was 75.
Now, Ocasek—Richard Theodore Otcasek in real life—wasn't known to be a petrolhead. So what is his obituary doing here? Well, we can think of two reasons.
First, obviously, is the fact that his famous band was called The Cars. Funny, because the group never really recorded songs dedicated to the automobile. You would think a band with such a simple name had the inclination to compose and perform car songs like The Beach Boys ("409" and "Little Deuce Coupe," among many others) had done earlier. But no, The Cars chose to sing about girls and parties instead. And many of them became defining soundtracks of a generation.
Which leads us to the second reason. One song The Cars made that is somewhat related to cars is "Drive," a heart-wrenching ballad about parting with a romantic partner. Sure, Ocasek didn't provide the lead vocals for the song (bandmate Benjamin Orr did), but he wrote it. "Who's gonna drive you home tonight?" the lyrics ask. The way we see it, the ditty enumerates the sweet things a person should selflessly do for a loved one (especially one who is hopelessly hooked on a vice):
Tell them things aren't so great
Pick them up when they fall
Pay attention to their dreams
Hold them down when they shake
And driving the beloved is one of those obligations. It may sound sexist now—women can drive for themselves, you know—but back in the day, giving your lady a ride was considered chivalrous. Try doing that today on a daily basis. On EDSA.
The iconic rock star famously married the ultimate supermodel of the 1980s. PHOTO FROM PAULINA PORIZKOVA
Of course, we also admired Ocasek for marrying supermodel Paulina Porizkova, who was about 19 years old when she appeared in the music video for "Drive." We '80s teenagers started believing that anything was romantically possible when the pair hooked up. When the couple revealed their separation last year, Porizkova wrote:
Our family always has been—and still is—a well-built car. When the four of us [including their two sons] are together, we can go wherever the road takes us. But as a bicycle, my husband and I no longer pedal in unison. So we're ditching the bicycle.
Farewell, Ric. We'll strive to chauffeur our own Paulina without complaining about the inconvenience. Because she gives us a reason for feeling alright.

Vernon is the founder and editor-in-chief of VISOR. He has been an automotive journalist for 25 years. He became one by serendipity, walking into the office of a small publishing company and applying for a position he had no idea was for a local car magazine. The rest, as they say, is rock and roll. He writes the column 'Spoiler'.
