- Q: If so, what time of year?
- oops, sorry, I had read crane flights. Crane flies - what we call 'cousin' or 'tipule' - are quite common in the Rhone valley, including Lyon though not as common as their dreaded relatives the mosquitos. They usually go dormant in winter as it is quite cold in Lyon during that time. They are harmless to Humans, even if they look terrifying but are a nightmare to gardeners. Edited: Wise Owl, I have lived in Lyon as well and I have seen them often enough to find it usual, though not every day of the week. However I lived near the Tête d'Or Park so the greenery might have had an influence on their presence here.

- Yes he Is r u sure u read it I read it a year ago know my boyfriend is obsessed with them he insist on me calling him Peeta I even remember him
- Q: Since a crane has to extend outriggers while performing lifting operation , is it ok to allow a crane to transfer materials by carrying without extending outriggers and lifting and carrying load to different location especially in construction industry for safety reasons?
- Yes, this is not only possible, it is done by cranes that are designed to operate without outriggers. There is a company called Lampson that has a whole product line of these cranes (see link). I have personally witnessed a number of lifts where an outrigger-less mobile Lampson crane moved a load in the multi-hundreds of tons during construction of a nuclear power plant.
- Q: Why do tower cranes need to be fabricated?
- The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3-4 times the same structure light steel wire rope (laboratory comparable conditions) with the research on the wear resistance of phosphating, and greatly enhance the possibility of. Manganese phosphating is bonderizing, can solve the wear problems of wire rope used in the process, according to the current market situation of wire rope, manganese phosphating coating of steel wire rope price is higher than that of plain steel wire rope, and prolonging the service life of much higher than the rate of price increase, so the phosphating coating steel wire rope daily use fee is only plain steel wire 30-45% rope, the use of lower cost, higher cost, smooth steel wire rope is eliminated. For reference only
- Q: It is my contention that God could be held accountable, at least as an accessory, for any crime. God had knowledge of these events in advance and did nothing.
- God is not a fallen man that He needs to defend Himself, who is there who can accuse God other than proud mistaken fools?
- Q: Can anyone help me interpret the poem Fear by Hart Crane? or North Labrador?
- Analysing Poetry Close reading may seem like a foreign and unfamiliar approach to analyzing a piece of text. However, it can often yield insights that will help you to create a unique paper developed from your own interpretation of the text. To analyze the work effectively, it is useful to concentrate on specific components of literature used to build and reveal the themes in the work. This process will help you explain how a passage relates to central themes in the text allowing you to reach an intelligent and creative thesis for a literary analysis. First, choose a passage (or a series of passages) that intrigues you.
- Q: I was given a CCRadio and I have no idea what it is or what it does.The guy that gave it to me says it's an Awesome DXing radio (whatever that means). The display doesn't work but other than that the radio works fine and pulls in alot of stations the previous owner said. Can anyone help me understand what a CCRadio is and what it does? Thanks to all that contribute.

- Q: Last week, I decided to make 1000 paper cranes as a new project. I am very craft- oriented, and have made numerous knitted scarfs, crocheted blankets (still in the works), and cross stitch patterns for family members. I have made 2 large cross stitch patterns, one for my grandma (took me 2 years to do) and one for my dad (2 months). My mom's birthday is coming up, and I was wondering if I should give her 1000 paper cranes as a present? I haven't yet given her anything that I made, and I feel bad about it. I don't have enough time to cross stitch a pattern or anything, and I can easily make 1000 by December. Would it be a sentimental present? Should I do it? Would she like it? If not, what should I get her? I want it to be something that I made so that it will be personal.
- Lol if you *really* want to be crafty... Get a spring (Or several) Glue it to the bottom of a box. Then glue a cardboard piece on top. Then put something heavy... (For example, a glass crane, shoudn't cost much) and put all the paper cranes under it. Then... when she opens the present and takes the glass one out the paper ones will fly everywehre :D
- Q: A Korean kid at my school made me one in a new kid meeting. Sadly, he made it with my hall pass that needs to be signed with the teacher that organized it. But when she had to sign it she ripped it up and he won't make me another one! How can i make one myself?
- Here are some links to pages that show you how to make the crane. You might also like to look for some general Origami pages, they will help you understand the directions if you run into a problem. Sometimes in origami you need to make a fold and then unfold it - the crease that was created by the un-fold will be used later - the instructions for this type of fold can be confusing. The first link is a step by step instruction site for the crane - very good illustrations with instructions accompanying each photo - it spans multiple pages so you need to click the next button at the bottom of the page as you finish each set of instructions. The second link is a full view of drawings of each fold on one single page - the instructions aren't as detailed, but it does give you the opportunity to see how each fold is supposed to look in one view. The third link is a link to a japanese site that explains the significance and history of the crane and what it means - it's very interesting. Good luck.
