We have synthesized a new green fluorescent dopant C-545P having incorporated five strategically placed "methyl" steric spacers on the julolidyl ring system. C-545P has good thermal properties and photostability, and when fabricated as a dopant in an Alq(3)-hosted OLED device, it shows notable improvement in luminance efficiency and is more resistant to concentration quenching than C-545T, part...

This paper presents the buzzing issue of green brick technology with the promises to protect the environment against the multidimensional damage done by traditional brick system. Bangladesh now facing a flourish in real estate sector that stimulates the brick industry too, but the very traditional brick making system destroys the diminishing forest of this country intensifying the emission of c...

1. INTRODUCTION The following problem is due to Paul Erdijs tll. Color the edges of a complete graph K on n vertices red and blue. What n is the largest t such that we may always find a complete subgraph in which I# red edges-# blue edges1 Lt? We need a more precise and more general formulation. For any set V, define Vk = {W :, w&V, Iwl = k). (1) Note that V2 is the complete graph generated by ...

For arbitrary graphs G1 and G2, define the Ramsey number R(G1,G2) to be the minimum positive integer N such that in every bicoloring of edges of the complete graph KN with, say, red and blue colors, there is either a red copy of G1 or a blue copy of G2. The classical Ramsey number r(k, l) is in our terminology R(Kk,Kl). Call a family F of graphs linear Ramsey if there exists a constant C = C(F)...

Background: Color vision has an important role in daily activities and also learning special talents in different jobs, especially in the field of medicine. However, they are many people all over the world that has no insight into their color blindness and choose the study fields that are completely dependent on vision. Due to the importance of color vision in the field of medicine, we conducte...
