Help for scientific article I need to explain a concept for a scientific paper. But I don't know if it is clear and if the grammar is right. I understand that it could be difficult traslate only a piece of the text. If there is someone that can try I would be very happy. "Results of measurements show how the RR (Retroriflective) samples have an evident tendency to reflect the incident radiation mainly backward to the incoming direction. In particular, when solar radiation reaches the RR samples with low incidence angles with respect to the perpendicular direction. When the radiation reaches the RR samples with high incidence angles, contrarily it is reflected symmetrically with respect to the perpendicular direction. This behaviour allows to rr samples to be employed synergically in urban canyon both on the walls and at the ground. It is possible understand such synergic interaction in a simple way comparing the different behaviour of diffusive and retrorifletive materials placed at the ground into the canyon model by means the optical geometry. When sun radiation comes from high incidence angles (like in the summer season) hits rr coating of the walls, this is mainly reflected into the ground of canyon (Fig. 1). The two different materials (diffuse and retroreflective) employed to coat the ground of canyon cause two different effects. Case 1. Retro reflective coating on the ground. The incidence angle on the ground is low. Hence the rr behaviour reflects the radiation mainly backward to the incoming direction that is the walls. In this case the backward radiation on the wall has a high incidence angle. Therefore the incoming radiation is mainly reflected out of the canyon Case 2. Diffusive coating on the ground The incidence angle on the ground is the same. However the diffusive behaviour reflects or diffuses the radiation. Therefore a lower percentage of incoming radiation goes back to the wall and consequently is lower the percentage of radiation that comes out from the canyon. This sample considerations can be verified by the measurements carried out in the Canyon model. The Results of measurements show that the percentage of outlet radiation close to the wall using RR coating, is higher than the one measured using diffusive coating. Similar considerations can be applied regarding the results of albedo in the centre of canyon. The orthogonal radiation on the ground is diffused by the diffusive coating, instead it is mainly reflected backward by retroreflective coating."

(1) Do you know the Umbria Region? I have just decided to present my Italian Region: Umbria. This Region is placed in the centre of Italy and it is full of woods (forest) so it is called "il cuore verde dell'Italia" (The Italian's green heart). The foreigns usualy know only Assisi such as city of Umbria because it was the birth city of S. Francesco. But I want to speak about other towns that iI suggest you visit. I can begin to talk abaut my birth city: Spoleto. You can reach it by train from Rome in an hour and a half. This town is perched on a hill (S Elia Hill). It is a Romanesque town where you can find a beautiful canstle (fortress) and especially you can visit the Romanesque aqueduct that is over 80 m high . The name of the canstle is (Rocca Albornoziana) because it was build by Cardinal Albornoz and in such castle the dougther of Papa Borgia: (Lucrezia Borgia) spent several a lot of time (you can see it in Borgias's series).

My first conversation Yesterday I did my first Skype call with a Italki user. I was very shy and I felt sometimes stupid. The caller is Astrualian and she was very polite. Unfortunately internet connection worked bad and I could just listen to 2 or 3 words for each sentece. I had to ask her to repeat again. She spoke italian better than my English and she studies Italian only for hobby. It is not easy to find spare time to talk. When I don't work I have to spend my time with my doughters. I have both to help the old one to do homework and to look after my young one (7 months). Also I have to help my wife for Housworks and at the end I want to do some activities (sports) to relax myself and to avoid that my body gets weak and my brein break down. I hope to find almost 2 hours a week to know you.

Juventus Lazio I m trying to waching the football match Juventus lazio for the leadrschip on internet. But my doughter is talking with her grandmather by thelephon and it is impossible serfing. So while my doughter is speaking about her cousin (now) about the fisch can swim (a very important speach) I wait for waching the football match.

I believed it was easier I believed it was easier to find somebody to talk by skype in Italki. However I can sadly understand that it is easier to find peaple who need that somebody traslates his thought. It isn't a problem...I hope that my traslation can help them so there are peaple who can help me. My aim was'nt this. My target is tmeeting foreign people from countries where you can speak in english. My interest is not only for my English improvement (that I need) but also for talking about what is happening in the word, and about what they think about Italy. I like knowing new kinds of music or dishes, different topinions. I persist... :-)

scientific paper I'd need to improve the conclusion of my scientific paper...(same parts are omitted) In order to valorise the bromure employment as sub product of process, an innovative plant has was tested on steam production by means of bromure combustion. The measurements of pressures, temperatures and flow rates are provided by XXX company, which installed the pilot plant ZZZZ in order to calculate its performance. The energy efficiencies obtained for the entire system are xx % and xxx %. Those values are comparable than the ones found in analogue studies for Industrial plants because the examined system is a pilot plant and it doesn’t produce energy (from economical point of view) as well as the boiler worked under low-load operating conditions. Technical adoptions employed in Industrial plant (xxxxxx) for energy production can easily improve such efficiencies. For instance, the employment of better thermal insulation materials or of preheating systems of water from exhaust gasses enhance the energy efficiency. xxxxx The results of campaign highlight the strengths of bromure employment within the mentioned technology. Differently from conventional plants, the xxxxx plant can employ fuels as the bromure with a low calorific value (probably also with much lower value than that assumed) with significant values of efficiencies (as shown in the present paper). Additionally it can recover the latent heat of water vapour of the exhaust gases thanks to the absence of nitrogen in the gas; it can adopt technologies to capture the oxigen present in the bromure with reduction of problems related to the durability of materials. It can also capture the ammonia produced by means of only physical systems of compression and condensation without the employment of absorption and stripping solvents .

Why dosn't my daughter sleep by night? This night my daughter didn't sleep. She is 6 month old and She falls asleep and wake up hourly everynight. I am tired but my wife too. Fourtunatly my daughter is vary nice otherwise who would be able to resist.

Information point Yesterday I was walking with my doughter when I saw two tourists that wolked before us Immediaetly I undestood that they come from north Europe. In Italy or south Europe it is difficult to find a middle age man that wears shorts and flipflap in April.They look that they are looking something or somewhere. So I thought to myself that they would have asked something.Ok... I was ready to strutter ..but I didn' care...I would have help them (?????). Then I approched them and they (XX) : Hallo! Could yo halp me!... (Iand I (Y) Yes of course..what are you looking for?. (XX) We are looking for the "Zentrum".....so I (Y) : Sind Sie Deutsch?. (XX) What? (Y) do you come from Germany?....(xx) NOOO... We come from ..xyxxxxzz ( I didn't underestand..it didn't metter)....(Y) The Centre is far from here...you have to come back. You have to go along this street and when you reach the end of the way you have to turn to the left...in Via Canali... so you walk for 500 meters and you find station square where there is the bus station. You can take Bus 1 (line 1)..it peaks you up until the center (Piazza Italia) Italian Square). (XX) Ah Ok thanks (Did they undestand what I said????)...Can we leave the car here... must we pay? (I write what I belive that they said to me)...(Y) No the parking is free on Sunday..don't worry. Have a good day!. My daugther looked at me like a Martian...and she asked me(in italian): Did you undesteand what they said to you?...Wow...I want to undestand too. Can you teach to me dad?. (Y) My love...When I have learned I will try...But you have to wait for many years.....I belive that it is bettere that you go to an English school... (She is studing English at elementary school....2 hours a Week..after two years she knows the names of 5 or 6 animals....cat.dog....there is no hope.)

My english life When I was a child I wished to be an engineer to manufacture schips or cars while my frineds wjshed to bejust a pilot or a football player. Then I studied scientific topics douring my school carreer path and when I decided which foreign language to study I chose the German one. Sombody said to me that German was the language of the future for the engineer. So I became an engineer that didn' speak english. Unfortunately when I meet people abroad for work or for pleasure evrybady speak english and my workmates too. Therefore I am the clown of the staff with my bad pronunciation and because I am the only one that ask to repeat slowly when somebody talks in English. Evereybody suggest to speak in English with English people. But where can I find them? Italki? Ok ...let's beginn. Here I am. I would like to meet people and in the future I woud like to meet them in their country and vice versa. I am married and I have two doughters ...we like travling... I loof forward to knowing new people and impruving my English. (I can help for Italian language)
