Properties of the scalar mesons f0(1370)f_0(1370), f0(1500)f_0(1500) and f0(1710)f_0(1710)

In the three-state mixing framework, considering the possible glueball components of $\eta$ and $\eta^\prime$, we investigate the hadronic decays of $f_0(1370)$, $f_0(1500)$ and $f_0(1710)$ into two pseudoscalar mesons. The quarkonia-glueball content of the three states is determined from the fit to the new data presented by the WA102 Collaboration. We find that these data are insensitive to the possible glueball components of $\eta$ and $\eta^\prime$. Furthermore, we discuss some properties of the mass matrix describing the mixing of the isoscalar scalar mesons.Comment: Latex 14 pages including 1 eps figur

Analysis of influence factors of free cataract surgery in suburban district of one city in middle China

AIM:To investigate the reasons of the barriers to free cataract surgery in suburban area of one city in middle China. <p>METHODS: From 2008 to 2009, in Sight Rehabilitation Programme of Cataract in suburban district of one city in middle China, all visually significant cataract patients screened were questioned about why he/she did not accept free cataract surgery. The answers were recorded and analyzed. <p>RESULTS: Of 892 screened patients, only 387 patients(43.39%)wanted a free cataract surgery at first. At last 490 patients(54.93%)accepted free surgery. The main reasons for patients who did not accept free surgery include: be afraid of surgery and wanting other treatments(193, 21.64%), thinking the eyesight was enough for daily life(148, 16.59%), worrying about that the result would not be good as those paid for surgery(147, 16.48%), and other reasons(17, 1.91%).<p>CONCLUSION: The reasons of the barriers to free cataract surgery include patients' ignorance, surgery outcome of patients around, and working mode of designated surgical hospital
