Unilateral sinus disease (USD) can sometimes be difficult to accurately diagnose before surgery. The application of nasal nitric oxide (nNO) for USD diagnosis and its surgical outcome in USD has not been reported in the literature. We prospectively enrolled sixty-six USD patients who underwent endoscopic sinus surgery for fungal rhinosinusitis (n = 19), chronic rhinosinusitis (CRS) without nasa...

Next Generation Networks (NGN, [1]) was the buzzword last year. Different people imagine different things when they think of NGN. How can this concept be defined? NGN is the application of Internet, IP and IT solutions to Telecom Services, including (but not only) the integration and sometimes the substitution of circuit switching with packet switching either for trunking or for access. Surpris...

This paper revisits a combinatorial structure called the large set of ordered design (LOD). Among others, we introduce novel Latin matching and prove that order n leads to an LOD(n−1, n, 2n−1); thus, obtain constructions for LOD(1, 2, 3), LOD(2, 3, 5), LOD(4, 5, 9). Moreover, show constructing is at least as hard Steiner system S(n−2, n−1, 2n−2); therefore, must be prime. We also some applicati...
