{sl let $[n]={1,dots, n}$ be colored in $k$ colors. a rainbow ap$(k)$ in $[n]$ is a $k$ term arithmetic progression whose elements have different colors. conlon, jungi'{c} and radoiv{c}i'{c} cite{conlon} prove that there exists an equinumerous 4-coloring of $[4n]$ which is rainbow ap(4) free, when $n$ is even. based on their construction, we show that such a coloring of ...
The Zarankiewicz number z(b; s) is the maximum size of a subgraph of Kb,b which does not contain Ks,s as a subgraph. The two-color bipartite Ramsey number b(s, t) is the smallest integer b such that any coloring of the edges of Kb,b with two colors contains a Ks,s in the rst color or a Kt,t in the second color.In this work, we design and exploit a computational method for bounding and computing...
The design of rug and carpets (kilim) have artistic values and capacities which are not known enough for the artists and scholars. As some of such motifs belonging to the carpets of the city of Jiroft have been extracted by the creative mind of artist without any direct connection with the nature, this paper focuses on such motifs which are similar to natural elements in their visual repr...
Background and Objectives: Pulse oximetry is the most common technique for monitoring hemoglobin oxygen saturation (SpO2). Different colors and brands of nail polish may cause disturbance in the reading and interpretation of oxygen saturation. The aim of this study was to determine the effect of different colors of nail polish on oxygen saturation measured by pulse oximeter. Methods: Thirty he...
Introduction: International Commission on Radiological Protection introduced three basic principles of radiation protection, namely justification, optimization, and dose limit. Medical exposure has no dose limits, and generally, diagnostic reference levels are used as a tool for optimization of patient protection. Material and Methods: Dosimetry was performed on 20 CT scanners located in 14 cit...

Let S be a set of n points in general position the plane. Suppose that each point has been assigned one k ≥ 3 possible colors and there is same number, m , color class. This means = . A polygon with vertices on empty if it does not contain its interior; rainbow all have different colors. f ( ) minimum number triangles determined by In this paper we give tight asymptotic bounds for function. Fur...
Introduction and purpose: Number of elderly is increasing in the world and as they grow older the risk of falling increases, accordingly. Visual disturbances are among internal risky factors of falling and meanwhile depth perception attenuation as one king of visual disturbances has the highest relationship with their falling. The aim of present investigation was to the effect of sports p...
