LICHENS AND AIR POLLUTION



WELCOME! BEM-VINDOS! TO ECOLOGICAL DAY!
Do you see "this" in your garden or neighborhood? If your answer is YES, luck you! There is no air pollution around you!

Você vê "isto" em seu jardim ou redondezas? Se sua resposta for SIM, sorte sua! O ar está limpo e não há poluição!






Lichens are a successful alliance between a fungus and an alga. Each doing what it does best, and thriving as a result of a natural cooperation. They live as one organism, both inhabiting the same body. ""Many lichens are very sensitive to pollution in the air. When there are too many harmful things in the air, lichens die. If you live where there are many lichens it probably means the air is clean. But, if there are only a few lichens in your neighborhood, the air you are breathing is probably clogged with automobile fumes or industrial wastes.

Lichens are capable of inhabiting several ecosystems, due to their versatility, despite of the environmental conditions. They can live on rocks, ground, rind of trees, trunks and wood. Lichens are very good bio-indicators to survey the air pollution.

So, Lichens are important in many ways: Lichens are sensitive to pollution in the air and can tell us if the air is clear and clean; Drug companies make antibiotics from lichen substances; Some lichens make nitrogen in the air usable to plants; Lichens are homes for spiders, mites, lice and other insects; Lichens can be used as a natural dye to color wool; People eat lichens (careful - a few are poisonous, so don't experiment without adult help).



Os Líquens são seres vivos muito simples que se desenvolvem como lâminas ou placas de várias cores na superfície de árvores ou de pedras, expostas à umidade e ao sol. São geralmente estudados pelos botânicos, apesar de não serem verdadeiras plantas. Os líquens são uma simbiose – um organismo formado por um fungo (o micobionte) e uma alga ou cianobactéria (o fotobionte). Os líquens são muito sensíveis à poluição do ar. Quando há muitos poluentes no ar os líquens morrem. Se você mora num ambiente onde há muitos líquens, isso significa que o ar está limpo e não há poluição. Os líquens são indicadores biológicos importantes que permitem uma avaliação da qualidade do ambiente.

Os Líquens proliferam nos substractos mais variados: sobre rochas, solo, casca das árvores e madeira. Vivem em ambientes onde nem fungos nem as algas se desenvolveriam. Assim, toleram condições climáticas extremas. Os líquens, apesar de suportarem os rigores ambientais, são extremamente sensíveis aos agentes poluentes, podendo indicar a qualidade do ar e até a quantidade de metais pesados em áreas industriais, o que explica a não ocorrência destes seres vivos nas grandes cidades.

Outra utilidade dos líquens: eles são comestíveis, mas cuidado porque alguns são venenosos, assim não os experimente sem a ajuda de um expert no assunto. As indústrias farmacêuticas usam os líquens na fabricação de remédios e os líquens também podem ser usados para colorir lãs e tecidos.

BLOG ANNIVERSARY THIRD

In September 29, I will celebrate the Third Anniversary of Leaves of Grass. I must to say that through blogging I've met a lot of nice, intelligent and funny people all around the world and it has been a great experience to me! I am having a wonderful and great time here!

To homage all my blogs friends I made this collage. My criterium was to pick up them from my links seeing on "Blogs I like to visit". This list is a work in progress, so I truly hope I did not forgot any person here.



About the photos, my criterium was to add a personal photo or a page's PrintScreen, when I could not find personal pictures to post. All pictures comes from friend's blogs and I sort them by alphabetic order. These photos has different sizes and I haven't the specific tool to make all them with the same sizes. So, the resulting image looks like a mosaic. I hope you like it.



Finally, I would like to thank you all my blog's friends who has been visiting, commenting and giving your lovely feedback.



No próximo dia 29 irei comemorar o Terceiro Aniversário do Leaves of Grass. Através do meu blog encontrei pessoas agradáveis, inteligentes, criativas e fiz reais amigos no mundo todo. Blogar tem sido uma experiência fantástica!



Para homenagear os meus amigos eu tive a idéia de fazer uma colagem. Meu critério foi buscá-los nos meus links, que estão no ítem “Blogs I like to visit”. Esta lista de links está sempre em movimento, assim, espero que eu não tenha esquecido de ninguém.



Quanto às fotos, meu critério foi adicionar à colagem fotos pessoais ou o PrintScreen da página, quando não encontrei uma foto adequada para postar. Elas foram copiadas dos blogs e estão dispostas em ordem alfabética. As fotos têm diferentes tamanhos e como eu não disponho de um programa específico para padronizá-las, o resultado foi um mosaico de fotos em diferentes dimensões. Espero que vocês gostem.




Finalmente, gostaria de agradecer a todos vocês meus amigos, que têm me visitado e feito generosos comentários.

THE BRIDGE AND THE SKY

Welcome to Sky Watch Friday





Photos By Carlos A. Mascaro






A cable-stayed bridge is a bridge that consists of one or more columns (normally referred to as towers or pylons), with cables supporting the bridge deck. There are two major classes of cable-stayed bridges: In a harp design, the cables are made nearly parallel by attaching cables to various points on the tower(s) so that the height of attachment of each cable on the tower is similar to the distance from the tower along the roadway to its lower attachment. In a fan design, the cables all connect to or pass over the top of the tower(s). Cable-stayed bridges can be dated back to the 1784 design of a timber bridge by German carpenter C.T. Loescher. Many early suspension bridges were of hybrid suspension and cable-stayed construction, including the 1817 footbridge at Dryburgh Abbey, and the later Albert Bridge (1872) and Brooklyn Bridge (1883).

Peugeot shows new 908 HY diesel-hybrid Le Mans racer!


In the current world of big time international endurance racing, two cars stand head and shoulders above the rest, the Audi R10 TDI and the Peugeot 908 HDi. Put these two Le Mans Prototype class 1 cars, both powered by 5.5L turbo diesel V12s, on a wide open track and nothing can run with them. With Formula 1 introducing hybrid kinetic energy recovery systems (KERS) in 2009 and the American Le Mans Series introducing a Green Challenge award, Peugeot has decided to take the next step with its program. The French manufacturer is using the last race of the 2008 Le Mans Series at Sliverstone to unveil a demonstrator called the 908 HY which may foreshadow the next generation of its Le Mans challenger. The 908 HY adds a 60 kW electric motor, a set of lithium ion battery packs and corresponding power electronics. The diesel hybrid system will allow the car to operate in electric-only mode in the pits, and get a power boost on the track thanks to recaptured kinetic energy. The current demonstrator has a net weight gain of 45 kg (99 lbs) compared to the standard car. Whether Peugeot runs a car based on this powertrain depends on the ACO, the organization that sets the rules for Le Mans.

New Honda City unveiled in Thailand - is this the look of the new Insight?



The new Honda Insight concept was teased last week in advance of the vehicle's unveiling at the Paris Motor Show next month. We don't know that the production version will look like, but it'll be similar in some ways to the concept and different in others. That's a cop out, sure, but what else is there to know? How about by taking a look at the 2009 Honda City, which was just unveiled in Thailand and is based on the Fit/Jazz. An anonymous poster wrote to Carscoop that, "We'll definitely see a variant of this in the US. It'll have a slightly different profile from the c-pillar back, be a hatchback and will be called the 'Insight.' Due at dealers in April..."

Last year, Honda became one of the first international automakers to take advantage of Thailand's financial aid packages to get more green cars built domestically. As to what the local vehicles might reveal about Honda's global line-up, go ahead and compare the two cars in high-resolution galleries below. Do you think that anonymous is right? Thanks to Rob for the tip.

Mercedes-Benz S400 hybrid to launch in June 2009 in Europe



Mercedes-Benz hasn't publicly announced an official on-sale date yet for its first hybrid models beyond the first half of 2009. However, BusinessWeek is reporting that the S400 BlueHybrid will go on sale in Europe in June 2009. The big gas-electric luxury sedan is due to arrive on U.S. roads one year from now. The S400 will use a lithium-ion battery pack and will likely be the first from a major automaker to do so. With a current U.S. base price of $86,700 for an S550, it's not quite clear where the hybrid will fit in the U.S. lineup. The S400 will pair the 3.5L V6 that is not available in the U.S. S-Class with the Daimler/BMW mild hybrid system. BusinessWeek reports the system will command a premium of less than €10,000 (I should hope so, since that's almost what Lexus charges for the full hybrid system on the LS600h). On the plus side, the Mercedes should get significantly better fuel economy than the Lexus. Mercedes is claiming 29.8 mpg (U.S.) for the hybrid although it remains to be seen how it will fare on the EPA cycle.

Rain Supreme: Big surprises at soaked Italian Grand Prix (SPOILER ALERT)


Racing fans are used to tuning in on the Saturday of a grand prix weekend to find the words "Scuderia" and "Ferrari" at the top of the qualifying list. But interrupted by the words "Toro Rosso"? Never. But that was only the first of many surprises at this weekend's Italian Grand Prix.

Sebastian Vettel shockingly secured his first pole position thanks to some exceedingly brilliant driving joined with good strategy on the part of his Ferrari-powered Scuderia Toro Rosso team, which wisely stuck with the extreme wet tires on the rain-soaked Monza circuit while others experimented with intermediate treads. The young German's unprecedented qualifying performance put him in the record books as the youngest driver ever to secure a pole position, supplanting Fernando Alonso's previous record. But with so many other drivers with more experience and backed by teams with immensely bigger budgets, surely Vettel's lead would quickly be stolen by an established front-runner. Wouldn't it? Follow the jump to find out.
