CO is one of the main air pollutant which leads to many problems for human. Mega cities such as Tehran have critical issues by increasing the vehicles, fuel usage and urban area expansion. Hence, to have a clear view points on the pattern of CO concentration in Tehran, the data of 14 air quality concentration centers in a midterm period (2009 and 2012) are used. The main novelty of this research is using the third quartile (Q3) as the pollution indicator which leads to more accurate results based on the exposure pattern in a day. Additionally, by Spline interpolation model and using ArcGIS software the zoning maps to show the CO concentration in urban area are illustrated and discussed. Using Q3 instead of the mean values showed more accurate results due to the exposure patterns. Due to the results, the CO concentration shows a downward trend and the most changes are in the Western side of the city.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

A Study on the Seismic Isolation Systems of Bridges with Lead Rubber Bearings

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52566#.VJt06cCAM4 Author(s)   Woo-Suk Kim , Dong-Joon Ahn , Jong-Kook Lee Affiliation(s) School of Architecture, Kumoh National Institute of Technology, Gumi, Republic of Korea . ABSTRACT This study consists of the development and presentation of example of seismic isolation system analysis and design for a continuous, 3-span, cast-in-place concrete box girder bridge. It is expected that example is developed for all Lead-Rubber Bearing (LRB) seismic isolation system on piers and abutments which placed in between super-structure and sub-structure. Design forces, displacements, and drifts are given distinctive consideration in...

Effects of Karate Training on Basic Motor Abilities of Primary School Children

“You never attack first in karate” might be the best conclusion of karate, which is a martial art practiced typically without weapons. It’s reported that karate has a long history for several hundred years, but the modern karate was spread to the whole Japan from Okinawa in the early part of 20th century. Now it has become one of the most widely practiced martial art forms in the world. Usually, it’s divided into Kihon, Kata and Kumite. As for the beginners, Kihon is more suitable for them because it involves basic techniques. Due to karate consists of dynamic offensive and defensive techniques using all parts of the body to their maximum advantage, the best understanding of true karate practice is the perfection of oneself through the perfection of the art. It not only develops coordination, quickens reflexes, and builds stamina, but also develops composure, a clearer thought process, deeper insight into one’s mental capabilities, and more self-confidence. So many researchers stu...
