![]() The cheap Birra is imperial, but you may want to try out the craft beers instead. In Costa Rica, you will find that there are many amounts of well-crafted beers and the locals are very happy to share it with tourists. This word means beer, just like in the Italian language. In Costa Rica, everybody loves sugar and that is why it was labeled “the happiest place on earth.” You will realize just how much Costa Ricans are addicted to all the sweet flavors. It can relate to stuff like candies, cakes, cookies, McDonalds’s, etc. There are a couple of phrases that you will identify Costa Rican people with the phrases that make the Spanish Costa Rica special and stand out from the rest.īelow are a couple of words you can look into and practice when visiting. The Spanish there is slightly different from the Spanish you know or have learned from other Spanish-speaking countries. With the little Spanish you know, you may be shocked at what you will realize when you visit Costa Rica. If you have been studying Spanish throughout your life, then it would be safe to say that you have caught a couple of Spanish phrases down the line. ![]() This funny expression means awesome!, great! or how cool! If you want a tip to remember it, just keep in mind that chiva literally means goat - So, it would be "How goat!".How to Talk Like a Costa Rican Local March 30, 2018 But the truth is that this warm nickname might be used by adults too. Kids from Costa Rica call their fathers tata. But be aware that too much guaro will bring you a goma! - a hangover. It can be also a wide term meaning just alcohol drinks. If you learn the term guaro, you will also need to know the meaning of goma! Guaro refers to alcohol beverages made from sugar cane, like rum. On evenings or during the weekend you will probably see friends playing a mejenga. "You should meet John, he’s tuanis.", could be a good example. No matter if you are talking about a person, a place or an activity, tuanis is the Costa Rican for awesome, cool or nice. Also, diay could stand for What do you mean? or What happened? Sometimes you will hear the term as a linguistic filler, if they take a pause when talking.įor example, "Do you think you will you meet her again? Diay, I don’t know." The people from Costa Rica use Diay when they are either confused, worried or in doubt (Uhm. Ticos play with the term among friends, but when used with someone you don’t know it could be offensive. Among men, it is also slightly pejorative. It can also refer to a woman, but that’s not so usual and it may have a pejorative meaning. For instance, "I met that mae some days ago". Meaning guy or dude, it is widely used among friends, but it can also simply mean man. Walking down the street you will probably hear mae many times if you come across a group of young people. For example "Shall we go to the beach today? I cannot come, I have too much brete." Or, "I am looking for a brete near my home." It means work, indeed, but they could also use it as a synonym of job or workplace. If a tico is talking about work, you will definitely hear the word brete. It could describe a wonderful beach where to practice surf or a great restaurant for eating gallo pinto. It is a term used to express that something is great. One would be "Mas tico que el gallo pinto", which means "More Costa Rican than rice and beans" (a delicious local recipe you will love). There are some nice expressions that show how popular the word Tico is. This is a nice example of how ticos love diminutives and they tend to create them by adding -tico as a suffix. Tico is the short form for Costa Rican - a man. For example, if you say "Goodbye, Lucas", the response might be "Pura vida!" Or iv you say "Hi, my name is Ana" the response might also be "Pura vida, I am Lola". Pura vida could stand for nice to meet you, thank you, see you later, you are welcome, as well as great! For instance, you may hear Pura vida as a reply to your kind goodbye. It simply means "Pure life", but you will see that locals use it in many ways.

That dudes page is full of kooky rants and minor misinformation and misconceptions, but ok fine, leaving that aside. Then - as to the "recalibrated" thermostats. Mine is now straight up around low 90's (which is what an 88C stat gives you really) You can code that same as M62 stock (so an 88C would read a bit low) but I have custom coded mine for 88C also, I have a thread on that somewhere. That one you CAN recalibrate w cluster coding. ![]() The actual coolant gauge is the one on the far right. So that's the thing that needs fixing and it isn't fixed in the cluster coding it is fixed in the DME Tune - Terraphantm made some OEM modded binaries people could flash as long as you weren't tuned or otherwise special. So for reasons I forget the cluster gets coolant temp instead and for some scaling reason I guess it pins the gauge. The M62TU DME (as opposed to the S62 DME) doesn't send the oil temp over CAN (without mods that is and if it is not a 4.6 or Alpina etc). And it displays a temp that's sent over the CAN bus. That oil temp gauge is what youre talking about right? The one centered below the tach? That's oil temp not coolant. So the cluster stuff is entirely different. It gets really hot in the summer here in LA. And yeah, I know what you mean, I'm not looking to run super low temps, just a little bit lower. Some later cars - seems like the 2002's specifically - seem to have DME software versions that will throw an SES occaisionally w/ the 88C because the DME is smart enough to notice "Hey! WTF! This engine is running too cool!" but seems like that's mainly just a subset of later cars.Thanks for the info and insight.

This engine is running too cool!" but seems like that's mainly just a subset of later cars. Single power resistor, zip tie it under the beauty cover, easy. ![]() The 88C is closest to plug and play for sure, but you need to make a resistor to fake the DME into not throwing a code because the 88C has no plug on it and the DME wants to see "oh there's a thermostat connected". There's even an argument that 88C is real cold - ie something like 'san's 95C or a 92C are the kind of thing that most BMW M motors get from the factory. ![]() 80C is frickkin cold prob not a good idea. so you really want to shoot for a sweet spot which is something around the 90's Celsius (the 88C T-stat means the engine runs generally in the low/mid 90's most of the time). But engines run w/ less friction at higher temps which means less wear and more performance. Too cold is not good, even though a lotta knuckledraggers think "you can't have cold enough" and "high temps are only for emissions!".

The droprate on PTR seems to be worse for me, but it could just be that I'm having bad luck.Ĭomment by ThottbotNote: Only Horde can kill the Dalaran Spellscribe. ![]() The spawn time seems to be about the same on the PTR (Patch Test Realm), although for the most part it was every 4 hours + 10 minutes. But I have gone for over 30 kills without getting one. Maybe one in 20 kills or so if I'm lucky. I did get a green recipe (I'll have to look again to see what kind it was) that isn't on the loot list here. I filled my bags with the jewel-encrusted sashes, maybe about 10 of the channeler's staff. Most of the time for me he/she would respawn after 4 hours and 10 minutes. The spawnrate seems to be between 4 hours + 10 minutes up to 8 hours (on only one occasion it was 10 hours, but I think I may have missed a spawn while grabbing something to eat). Whenever he/she spawned I would check the smaller buildings first and then inside the large one and one-shot kill him/her. I had the sound set so that if there was any combat I would hear it happening and be able to check. I had my orc death knight sit at Ambermill for hours on end, spamming the target macro every few minutes and checking the combat log to see if anyone else had come by and attacked the spellscribe. I only managed to get those once as the droprate is horrible. I also got a tabby from a Dalaran Shield Guard. Between spawn times I hunted Dalaran Summoners and got one tabby. The droprate on the tabby is not very good. It also makes a difference whether you buy/sell at a Horde AH or neutral, of course.Ĭomment by kyntheaI've been camping the Dalaran Spellscribe for a few weeks now. I've sold my boxes for anywhere from 600g on the low side to 1600g on the high side.

Also, the location changes as well, in a similarly random manner. The timing of the spawns changes and does not repeat intra-day or inter-day. Some days it will spawn 2-3 times, some days never. It changes from day to day and from hour to hour. The trouble is, there is no pattern to the spawning of the Spellscribe. Out of 40 spawnings of the Spellscribe that I have seen, I've collected: I've mapped out the times and locations of each spawning, the location and the drop. :)ģ hours of doing quests is nothing compared to most farming, plus you don't have to check the AH 50 times a day hoping a Horde has realized it is a valuable item.Ĭomment by insinu8I have been farming this pet on and off since January. Dropped the cat second try (however I think I'll get a few more to make some cash). I've had the mob spawn twice since I made my Horde character yesterday. Just get a guild member or someone you trust to get into position while you put it up on the AH for 2 copper. So don't go putting it on the neutral AH and then login with an Alliance character hoping to buy it from yourself. You're stuck with the same faction.Ģ: You cannot bid on your own auctions. When you've finished the quests you have all the flight paths, so head to Silverpine and camp there until you have one and zip down to Booty Bay.ġ: You cannot make a Horde if you are on a PvP server and play Alliance. Simply make a Horde Death Knight, do the starting quests (3 hours or less) and take the flight path straight there. Comment by ForcedPerfectTo all those Alliance players who want this item, but don't want to spend a ton of gold on the AH or spend 6 months waiting for it to even appear, you might want to do what I did. ![]() On the plus side, if you need to practice your eighth and sixteenth notes over triplets, this is a great piece for that, because it repeats the same eighth and sixteenth patterns over triplets, using the same notes, over and over and over again. Now, I know this is supposed to represent Beethoven's unwinding while going into the woods and getting away from the stress of civilization, but that doesn't make it musically interesting, at least to me. I was surprised by how repetitious it was. It is very repetitious, playing the same motives over and over again. The development, though, is surprisingly bland. It works musically, the great theme is there. ![]() My mind would start to wander, after being enthralled by the first half. In fact, that happened to me with the second part of the 1st movement also. The rest of the movements I'd sort of zone out and lose focus when listening (usually in my car). I'm not super familiar with the symphony, but the only movement that really wowed me was the 1st. Peters edition of Beethoven Symphonies 6-9, edited by Otto Singer, largely for the 6th. I will be seeing Frederic Chiu perform the Beethoven-Liszt 5th Symphony in concert in a few days. It has finally been purchased by someone else, but I do not find my procrastination troubling, even as I'm sure Katsaris would easily eclipse any other set.Why would I listen to Beethoven's Symphonies on the piano when I have recordings of Furtwänlger, Scherchen, Szell, Klemperer, Weingartner, Mengalberg, Asahina, Abravanel, Krips, Munch, Monteux, Kleiber, Koussevitzky, and others conducting fine orchestras in perfomances of far more expressive power? I use the Liszt transcriptions as a means for my own private access into this world without currently being a conductor and having access to an orchestra, and there is their merit. Every time I went in I thought of buying it, but instead walked out with other material. In a local second hand shop, I had seen for a number of months, a sealed copy of Katsaris's recordings of all the Symphonies for a very reasonable price. I'd love to do the 3rd, but.here I may make my own transcription, for in Liszt's writing, as in many of the others, the Symphony simply does not translate well to the piano. I've often times played around with the 7th and it has reaped musical awards, but the scherzo and finale are quite imposing for these pianistic short comings. It's just my opinion that the Liszt-Beethoven Symphonies are very unpianistic.easily the most unpianistic thing he realized. ![]() ![]() ![]() Below, we’ve detailed cost ranges for some of the most popular metal roofing types and factors to consider. Tin roofs aren’t one-size-fits-all you have multiple styles and types to choose from. How Much Does a Tin Roof Cost by Metal Roofing Type? Learn more about the pricing of other kinds of roofing shingles and read our article about the pricing of rubber shingles for more information. The rough costs listed in this article include bare materials and labor fees. We retrieve cost data from RS Means, a project estimator for contractors and home improvement experts. Here are some cost approximations for a standard 1,700-square-foot roof: Cost Range Such projects will likely exceed $30,000 for standard roof sizes. Premium-coated metals or complex roof configurations will produce a higher tin roof cost of about $14–$18 per square foot. On average, a tin roof costs between $10–$13 per square foot, or $100–$130 per square (a roofing term used to describe 100 square feet.) The lowest price range for tin roofing is between $4.50–$8.50 per square foot or $450–$850 per square. Your initial metal roof investment will undoubtedly be high, but the roof’s durability, energy efficiency, and curb appeal will pay off for decades to come.This durability also gives the material a long life span of 40–70 years, compared to asphalt’s 15–30 years.On average, a tin roof costs between $10–$13 per square foot, or $100–$130 per square (a roofing term used to describe 100 square feet.).Best Lawn Care Service for Service Dogs.Lighted Magnifying Glass That Stays Put.It is time to dispel the unfair rumors and myths about metal roofs. Metal roofs are clearly the all-round green roof for any homeowners who are serious about comfortable, cost-effective, and efficient roofing solutions. Widely coveted for their fire-resistant and strength, it is common for metal roofs to live to see their 100th anniversary of service. This is because metal roofs are also much more durable than asphalt shingle roofs, and as a result of their durability, they tend to last much longer. Not stopping there, metal roofs are extremely eco-friendly because they are made of 100% recyclable materials and are completely toxin-free!ĭeterioration is also of little concern for homeowners with metal roofs. Known for their strong solar reflectance value, metal roofs will keep your house cool during the dog days of summer by reflecting as much as 40% of the solar radiation. In addition to serving as a great line of defense against noise pollution, metal roofs are also energy efficient and eco-friendly. In reality, they can be quieter than your typical asphalt shingles. Because of this, metal roofs can effectively reduce noises from rain, hail, windblown debris, and other extreme weather conditions much better than other roofing materials. When a metal roof is installed, it comes with strong sheathing that goes between the metal roof and your existing roofing surface. This is because your typical metal roof is no longer directly installed over your roofing surface. The truth about metal roofs is that they aren’t any noisier in the rain than a traditional asphalt roof. Nonetheless, this method of metal roof installation is long outdated the rumor that metal roofs are loud is but a remnant of an old concept. The reason metal roofs may come across as a resounding speaker in earlier times is that they were directly installed over rafters and held in place by exposed fasteners (a perfect recipe for rattling). Chances are they imagine the legendary barn or farm roof that makes a great racket in heavy rain and hailstorms. In fact, many make their deductions about metal roofs based on the simple fact that the roof is made out of metal. It might surprise you that the claim metal roofs are much more noisier than asphalt shingles is made by misinformed people who do not know much about metal roofs. However, the saying that metal roofs are noisier than your average asphalt shingle roof is in itself a myth. For those living on busy streets, having a roof that is impervious to the rising noise pollution is extremely important. Every homeowner dreams to have a quiet home. The myth that metal roofs are noisy is especially detrimental to their popularity in the roofing and home improvement industry. Yet, they are often misjudged as heavy, prone to lightning strikes, and overall noisy. Metal roofs are a sturdy, quiet, and energy efficient roofing solution. ![]() They are known for their versatility and practicality.

Animals eat the plants so they too have carbon-14 in their tissues. but the carbon-14 decays away, at a constant rate, making carbon-14 a ticking atomic clock. 14 N (n,p) 14 C 14 C can also be produced by the following reaction: 13 C(d,p) 14 C d: deuterium or 2 H the production rate is 2.4 0.2 atoms (cm 2 sec)-1 Radioactive decay 14 C decays by b-decay with a maximum. The length of time it will take for half the amount of carbon-14 to decay is known as its half-life. ![]() Plants take in carbon-14 through the process of photosynthesis.

Solution One mole of carbon has a mass of 12.0 g, since it is nearly pure 12 C 12 C. The amount of carbon-14 in the atomosphere is, on an average, relatively constant. A sample of radioactive isotope A and a sample of radioactive isotope B decay as shown in the graph below. While an organism is living, it takes in carbon from the atmosphere and the ratio of carbon-14 to the stable isotope carbon-12 in the organism is constant. The decay constant is determined from the known half-life of 14 C 14 C (available from Figure 10.4). A species half-life is the time is takes for that species to decay. The 14C/ 12C ratio in living organisms is 1. Carbon-14 is a radioisotope formed in our atmosphere by the bombardment of nitrogen-14 by cosmic rays. Radioactive dating is a process by which the approximate age of an object is determined through the use of certain radioactive nuclides.For example, carbon-14 has a half-life of 5,730 years and is used to measure the age of organic material. The value of k for carbon-14 is 1.21 x 10-4 year-1, which comes from the half-life formula. ![]() The half-life for this reaction is 5700 ± 30 yr.
