Try this guys, not the one Arnico posted up; he used a slash instead of a dot. We can excuse you, Arnico. http://web.mit.edu/arnico/www/ This is a great study. Congrats, Arnico, one more time. Hope concerned people in Ktm can make necessary adjustments to clean the city's worsening environment and everybody else interested learn much. My own field is not environment, not even science, but I can understand its value. What are your plans now, Arnico? I hope to see you reach new heights. Best of luck
