- Q: I'm supposed to be critiquing an article for a class of mine.. and I don't feel like I understand the concept enough to critique his use of it... (It's an article about The Red Badge of Courage... the author talks about how the observing narrator Stephen Crane creates in the novel uses patterned reality without ambiguity... he's describing one of the scenes in which the dead soliders are somewhat personified.. describing them in terms of the living...... erm anyone take a class on realism? your help is greatly appreciated
- The okorder
- Q: I have a vessel 40 feet off the ground in a platform, and the crane can get to within 30 feet of it (from the side). I'm more curious of the process for sizing them though.
- As you won't be building your own crane (that would be stupid since you would be fully liable). Call a crane vending/renting company. They'll be more than eager to provide you with technical council. How you pick a crane? What do you need to do with it - type of crane for instance -Moving stuff around in a warehouse, yard,.. always at the same places = overhead crane -Lifting heavy stuff once (for instance another crane) or for a short period - mobile crane -lifting stuff for a longer period but not permanent (construction) = tower crane How much do you need to lift, what can it cost? ... It's al pretty simple
- Q: would someone who study both white crane kung-fu & ninjutsu be called a mixed martial artist?
- It is mixing two martial arts but its not mma. MMA is more for fighting. While the styles you speak of are thought to be more of an ART. White crane kung-fu is not even used today and very rare to find. Most people that claim to teach it are probly teaching there own crane style. That goes for the same as ninjutsu. Both I styles i find to be not affective when matched up against an mma fighter. Some people from watching movies have this belief that ninjutsu is some deadly art when what is left of it today is not. Ninjutsu has not evolved and does not possess the ground game the brazilian Jui jitsu posses. Its also widely known that finding a true ninjutsu school is next to impossible. Now to Emerald. Your wrong. I must disagree with just about all your points. Its widely known that Boxing is the oldest known martial art in the world. Next to that is wrestling. You forget that another popular style among MMA practitioners is Muay Thai which has been around just as long as kung fu. It is also known to be one of the most powerful styles used today. Sorry to say its been proven that a master of one art will lose to a master of BJJ. We all remember the gracie challenge that got this started. U must of never seen all the karate and kung fu guys get choked out. Ignorance is bliss. Your styles failed and that is why they are no longer is use in mma today. Watch the UFC then watch your karate point sparing. Think about it.

- my daughter's art club did this for a hospital not to long ago...they made 1300 paper cranes and hung them from the ceiling in one of the hospital wings. I don't know about being granted one wish, but it made the patients happy and smile no matter how sick they were. I've heard the paper crane was some how connected with leukemia, so she made one for a friend of mine's son (he is only 7 and has battled this disease for 2 years) and it made him happy to know that someone who doesn't know him would make something like that for him.
