4‐valent graphs

Journal of Graph Theory, 1982
AbstractLet {pk}k≥2, k≠4 be a sequence of non‐negative integers which satisfies 8 + Σk≥3(k — 4)pk = 0. Then there exists an integer p4 such that there exists a 2‐connected planar graph with exactly pk k‐gons as faces for all k ≥ 2. This paper determines all such p4 when pk = 0 for k ≥ 5 and determines that there is a constant C ≥ 1 such that for some m

Cost-effectiveness of conjugate pneumococcal vaccination in Singapore: Comparing estimates for 7-valent, 10-valent, and 13-valent vaccines

Vaccine, 2011
Although multiple studies of cost-effectiveness of pneumococcal conjugate vaccines have been conducted, no such study has examined Singapore's situation nor compared the licensed conjugate vaccines in an Asian population. This paper estimates the costs and public health impacts of pneumococcal conjugate vaccine programs, varying estimates of serotype ...

Comparison of aerobic atrazine degradation with zero valent aluminum and zero valent iron

Journal of Hazardous Materials, 2018
This study systematically compared the degradation of atrazine (ATR) with aerobic zero-valent aluminum (ZVAl/Air) and zero-valent iron (ZVI/Air) systems. By comparing the ATR degradation curves and rate in the ZVAl/Air and the ZVI/Air systems, a significant induction period was observed in the ZVAl/Air system, and the pseudo-first-order rate constant ...
