  • How big of an earthquake can earthquake proof buildings withstand??
    Qlandav2ex_small

    The important distinction here to make is that the retrofitting of your older brick building has been done to ensure the survivability of the residents not that the structure itself is going to be undamaged. That is, that the building will maintain enough structural integrity to not collapse in the event of a seismic event. Prior to the retrofit your building would have been termed an "unreinforced masonry building" (URM). These structures tend to crumble and fall apart with seismic shaking. With those fittings and cables providing tension and forces to keep the structure together during an earthquake the living spaces have a much better chance of maintaining integrity for the survivability of the people within. I would suggest your term of being "earthquake proof" is only applicable for minor to maybe some medium level events (some that would have taken the building down before retrofit). The very high scale of the possible events for this area are going to cause significant damage to many if not most structures that are of significant age.

    Reutte covers the points about the strength and depth issues of quakes and how that affects movment. The point missing was that the Nisqually quake was centered some 40 or more miles away from Seattle. Liquefaction not only might cause some sinking but more importantly can magnify movement at the surface. There are many areas of Seattle built on filled areas that can experience this other significant effect of ground movement.

    I assume you understand the how the magnitude moment numbers work, but for those who don't that magnitude 9.0 event will be 1000 times greater than a 7.0 event. (The 2001 Nisqually earthquake was eventually rated at 6.8.)
    See: http://en.wikipedia.org/wiki/Moment_magnitude_scale

    This document is the report of a 2007 survey of URM buildings:
    http://www.seattle.gov/dpd/news/URMfinalreport.pdf
    It will not answer your question per se but you can get the scale of what possible damage is likely to be the result of a big event.

    I assume that the specifications of the retrofit done on your building would be the best information to consult and should be available with some research. I would suggest contacting the Seattle Department of Planning and Development to start and see what you can find out about your building.

  • Are natural fabrics and textiles biodegradable?
    Qlandav2ex_small

    In the strictest sense they are biodegradable, that is that given time and exposure to bacteria and micro-organisms and the action of other processes that degrade molecular bonds (UV light exposure) they will break down.

    Putting them in a compost pile would not be an effective way of recycling their materials and would probably introduce numerous chemical dyes and other compounds into the product obtained (as explained by others here).

    Cotton fabric and wool sweaters can be recycled into other economically productive industries by donation to Goodwill or other agencies that clean and separate material like this for resale to secondary product manufacturing concerns.

  • How does Youtube decide the order of search results?
    555_pinout_small

    I don't know, but since YouTube is a Google company I can take a pretty good guess:

    1. Google's search algorithms are extremely complex and sophisticated. Furthermore they are designed to try and ensure that no one can figure them out easily enough to game them.

    2. Google typically ranks results based on the behavior of viewers and site owners. So if a lot of people link to a given video or embed it then each of those instances is considered a "vote" for that video.

    3. They will also incorporate things like actual votes, views, keywords/tags, etc.

    4. I'm sure they also rank videos based on how much of the video was watched. Did people abandon it after a 30 seconds or watch the whole thing.

    So the short answer is that it is designed so that you cannot easily figure it out and it incorporates every bit of data about the video that is available - esp. the behavior of other sites and people watching.

    Hope that helps a little.

  • What is a website that will update me on up coming celestial events?
    Spaceship_small

    May I recommend www.spaceweather.com

    This daily news magazine not only covers celestial events, but all things space, astronomy and NASA related.

    They can send you alerts...for events, sightings, and meteor showers, as well as other events of interest.

    Or, you can just check regularly for the latest.

    Nice photos, great graphics, and simple language for the layman.

    Extra feature: The wayback device lets you go back in time to read ealier editions.

  • Planet X?
    Spaceship_small

    Planet X was a name for what became identified as "Pluto" ...but it also has been used at various times to identify any unknown, or suspected planet...

    In the awful 1960s sci-fi flick "Journey to the Far Side of the Sun", an astronaut who is lost in space, returns to the earth and discovers that he's on a duplicate of Earth that orbits exactly opposite the sun from us, in a place we can never see...and gets confirmation when the polarity of the electricity in the capsule is reversed...unfortunately, dooming him to crash land and never getting the story out.

    There's also been a theory that a rouge planet will sweep in and either: 1) Collide with Earth, 2)Collide with the Moon 3) Near miss, causing tidal forces and disaster, 4) take up orbit with us, etc. 5) rip us away from the sun,etc.

    Take your pick of which theory you want. Why? What did you hear?

  • Are you upset that the UARS satellite may have fallen to Earth near Seattle?
    Rex_racer_small

    Sorta. I'm more upset that we're so flippant about uncontrolled littering of a bus sized piece of junk. The fact it could kill people sucks too.

    Also, doesn't it take considerable expense and technology to PREVENT the space shuttle and capsules from burning up? Why doesn't this thing burn up -- did we accidently make it out of ceramic re-entry tiles?

  • Less hungry from whole grain carbs?
    Bauhaus_small

    The scientific explanation suggests that slowly digestible carbs (whole grains) don't spike insulin levels the way white flour, sugar, refined carbs, and fruit juices (and alcohol) do. Sugary Chinese food is notorious for satisfying hunger for about an hour and then you hit the leftovers. When insulin spikes, blood sugar decreases, and one then feels the need to eat again to get the blood sugar level back up starting the cycle all over again.

    But here's the thing...carbs are fairly calorie intensive and portion control must be exercised or you're going to gain weight. Personally speaking, if I get on a sandwich kick (even using whole grain, healthy bread), I find myself eating more and more frequently. Bread in all forms satisfies hunger but only temporarily. And I can eat a wheel barrel full of whole wheat pasta - enough of it until I'm sick-full, and two hours later I want another helping of spaghetti (or whatever).

    It may be genetic. I know runners, for instance, don't usually have to worry about carbs because they burn it off. But I have to avoid or limit carb intake or I balloon up in no time. It isn't that way for everyone, but it is definitely that way for me.

    And that USDA pyramid is well-known bullshit. Twelve servings (even half-cup servings) of grains a day? Can you say "wheat lobby?" I'd weight 500 lbs. if I followed its recommendations.

  • Is it possible to get someone's DNA off of a book if they handled it at some point?
    Qlandav2ex_small

    What you are talking about, I believe, is referred to as contact DNA. This is becoming more feasible, with the tests becoming more sensitive and smaller samples being required. Of course, there would have to be skin cells or some nuclear material left behind. Also if the object was handled by other people you would have contamination from other DNA being present. Objects like cigarettes and soda cans that are touched by the mouth are more likely to have the DNA of only one person. Plus we shed whole cells more often and reliably by our lips and the soft mucousal tissues of the mouth.

  • How long do flies live (w/o enough food)?
    Qlandav2ex_small

    My experience has been that the window screen trapped fly constantly crawling about looking for an exit will meet a natural end within a day or so, basically succumbing to starvation, and stress from being subjected to less than ideal temperatures. An active fly will seek out the temperatures it needs to survive for resting at nightfall or other times.

    Here is a more detailed answer that considers all of the aspects of where it is in its life cycle, etc. and hard to beat for completeness.

    One method to use after you get that pesky fly trapped in the window is to suck him into your vacuum cleaner using the bare wand on the hose. With the vacuum cleaner turned on you can sneak open the window and grab him when he is close. This vacuuming can work when they are crawling on a window pane searching for a way out also. It will save you having to see the insect active, hear him buzzing and having your open window out of service for a day or so. The forces involved in being sucked up by the vacuum is pretty violent and will likely end its life plus the dry dusty environ of the collection bin or bag is not conducive to survival.

  • Could you die if your cell phone falls into the water while you're taking a bath?
    Avatar_default

    Nope. Generally direct current voltages below 40-60 volts are considered completely safe (depending on the regulating body) and realistically the voltages need to get up to 75-100 volts in order for current to actually flow through a person (depending on the human body). Your cell phone battery is probably somewhere between 2-6 volts and so there is no way in heck it will flow through you.

  • Do You Trust Science?
    Medium_2868373187_b2c11c89cf_o_small

    I don't necessarily trust every study or report that I read that is based in science, but I do trust science a method.

    Ultimately, science works itself out, figures out a lot of shit, and generally approaches the truth better than any other system ever created by man.

    In the process, it makes a lot of claims and sometime even errors - but the test of time, and more science, corrects it.

  • It is said that beetles called rice weevils are found in rice.The weevils appear to come from rice.Is this true?If it is not,Explain.
    Qlandav2ex_small

    Rice weevils (Sitophilus oryzae) are beetles (Class/Insecta, Order/Coleoptera) that feed on a number of different grains including rice, corn and wheat.

    The female deposits and seals an egg in a hole that is made in a single grain and the developing larva eats the grain from the inside out as it grows.

    Being difficult to control, grain sold as food can contain some contaminated individual grains. Stored at room temperature existing eggs and larva can mature and continue the life cycle feeding on the readily available food source. The loss of food grain can be prevented by freezing it below 0° Fahrenheit for three days to kill any eggs or developing larva.

    Small beetles found in flour probably were there in the product (in egg or larval form) when you bought it. Storage in airtight containers and freezing for a period of time also will curtail an outbreak and eliminate problems.

    Other recommendations include buying small enough quantities of these products so that you use your grains and flour up in a reasonably short period of time.

  • What bug is this?
    Qlandav2ex_small

    That is a house centipede.

  • PHP vs. Rails for web-app development?
    Avatar640_31_small

    Comparing PHP to Rails is comparing apples to oranges. PHP is a programming language; Rails is an MVC framework.

    Do you really want to compare MVC frameworks like Rails, Django, CakePHP, and Catalyst?

    Or compare programming languages like PHP, Ruby, Python, and Perl?

    The "right" answer in my opinion is either Python+Django or Ruby on Rails.

    PHP is an annoying language because it has about a thousand or two built in subroutines, most of which do the same thing just very slightly different ways. I've never liked PHP but CakePHP is a mature MVC suite.

    Perl is the swiss army knife of languages but gets a lot of flack because it's so loose and lets you do crazy things and the current MVC frameworks kinda suck. Catalyst sucks, but Mojolicious (its successor) is up and coming and looking alright so far... not mature enough yet.

    Python is a cool language (it's Google's favorite, they hired the creator too) and Django is very mature but it's also pretty complicated and possibly overkill.

    Never used Ruby or Rails, but several people I know who work for serious shops that you've definitely heard of all code in it. It is also possibly overkill.

    Mr_small

    Thanks for your answer, Reutte. This soil liquefaction sounds scary. What do you think would happen to areas like Pioneer Square where there is a rather hollow structure underground?? I work in the area and my "office" is actually located in the lower level... I might be pancaked.. Anyway, I'm actually from Japan (in fact, my town is only about 50 km from the troubled nuclear plant... sigh..) I'm used to earthquake, and educated/trained regarding how I must act in case of an earthquake. And yes, the system there is well organized. Most damages and deaths in the last year's quake were due to the massive Tsunami, not because of the quake itself. The thing is, we've NEVER experienced a large Tsunami like that, and although everyone rushed towards uphill as soon as the shakes stopped and the warning was announced, the wave was too fast. So, if you see the list of the deceased, you see that most of them were elderly, 70~90 years old who couldn't move fast enough and those who were helping them move. Also it really didn't take long at all till things got relatively normal, and the clean up was finished. Anyway, as I don't feel that Seattle is well prepared for such catastrophes, I started to educate myself a bit and plan/ prepare. Knowledge might save my life. Thanks again for your answer.

    Oh, thanks, Russ. Your answer is always so educational. Well, I contacted the management company about who to contact in order to find out exactly how the "earthquake proof" of my building was retrofitted, etc., instead of contacting the Seattle Department of Planning and Development. - I thought it may take longer for the city department to respond to my inquiry.

    You'll find that virtually ALL non-commerical public broadcasting stations on the FM dial are clustered down to the left hand side of the dial. But there is nothing that prevents a broadcaster with a frequency elsewhere on the dial (in the commerical portion) to go "public" or "non-commerical" in their operation. They just have to be able to prove their operation is "in the public interested, convenience and necessity", which is the yard stick by which the FCC measures all station performance. THEY are the authority who assigns frequencies, power, and licenses broadcasting operations.

    Oh Oh! What a good question. I just did a little research and discovered that KUOW used to broadcast on 90.5, and KING used to be 94.9. Then, Dorothy Stimson Bullitt moved KING to 98.1 and donated the 94.9 transmitter and license.

    Dorothy Stimson Bullitt, if you're not familiar, is a Seattle Legend. She's the woman who built KING5 and KING radio. They called her the "Queen of KING."

    In the early days of broadcasting, call letters were were assigned to anyone operating broadcasting equipment, without much regard to arranging them into memorable words or patterns. Ms. Bullitt was one of the first people to recognize that memorable call letters could help market the station. She tracked down the owner of the broadcasting license with the letters KING, a fishing boat captain, and asked him to sell KING to her. Legend has it that the boat captain said she could have it if she made a donation to his church. Legend further has it that she made the donation, and personally rowed out to his boat on Lake Union with a bottle of Champagne to celebrate.

    Oh! This is the stuff of Seattle Legend. I might have to write a blog post about it....

    Wow, so there you have it, KUOW is one of the only mid-dial NPR stations in the country because Dorothy Stimson Bullitt donated the old KING transmitter.

    Seattle legend and lore, for the win!

    I was wondering about 94.9 too. In other cities I've lived in, the local public radio news station was between 89 and 91 FM; it surprised me that here it's in what I think of as the middle of the dial.

  • Comment on Mahtli69's answer…
    Spaceship_small

    You are correct about the "public" Non-commerical frequencies being at the lower end. Thanks to Freta Hennock lobbying the FCC decades ago, that spectrum was set asside.

    On the AM band the lower the number, the further the propagation, and so, lower numbers were more desirable. But it aint all that way.

    I hadn't thought about the middle of the dial being considered more valuable.

    I love KEXP, it's an awesome station, but their signal throw is pretty weak. Half the time when I'm running around in the car It's because I'm going somewhere far away, like Aberdeen or Portland or Friday Harbor. I always try to take transit in the city, so ironically, the times that I'm within range of KEXP are the times I don't have a radio with me. I wish there was a station like KEXP with 100,000 watts like KOMO that could throw a signal from Vancouver Washington to Westport to Friday Harbor to Ellensburg and play good music too. First World Problems of a Washingtonian I guess.

    Most memorable episode: The aftermath of Hurricane Andrew, having wiped his beloved animal preserve off the map had a pronounced effect on Jack.

    I suspect this is the reason why they kept reporting there might be as many as 26 "pieces" surviving to impact the Earth. That allows for the majority of it to burn up upon re-entry, and for some larger, heavier parts to survive in a burned, inert manner.
    Since this bad boy was launched, NASA has had to have re-entry policy and plans for ALL launched items... planning on how and where and when it will come down..and how to control it.

    I suspect that at the end of it's usable life, NASA steered UARS into an orbit that would take in mainly over water, with the anticipation that a lot of it would burn up upon re-entry, and that which did not, might stream into the Pacific over a long track.

    But you can't convince men that NORAD and the national defense system wasn't on alert with ICBM's at the ready, watching to see if this bad boy was going to take a dump on the lower 48 states. I can just imagine a few radar operators and a general staying at high alert for the last few days with a finger poised over the button.

    If say, the bulk of it was headed for L.A. or NYC or Chicago, I suspect a little ICBM would have gone up to meet it...and been dismissed as "lightning" or "burned up upon re-entry" so that we'd never have learned what they had to do to protect us citizens.
