Cutaneous leishmaniasis in al Hassa, Saudi Arabia: Epidemiological trends from 2000 to 2010

引用

Asian Pacific Journal of Tropical Medicine 2013年第8期6卷 667-672页

作者： Tarek Tawfik Amin Hamdan Ibrahim al-Mohammed Feroze Kaliyadan Balghonaim salah Mohammed King Faisal University Cairo University Vector Control Unit Preventive Medicine Department Local Health Directorate Al Hofuf Ministry of Health

Objective: To study epidemiological trends related to cutaneous leishmaniasis (CL) in al Hassa, an endemic area in Saudi Arabia. Methods: This retrospective study included the spatial/ temporal analysis of the reported cases of CL using the available surveillance database for the disease at the regional Vector Control Unit, from 2000 to 2010. Results: The incidence of CL was declining at a stable rate especially during the last 3 years of the study (2008-2010). An interesting finding was the percentage of expatriates affected was increasing over the last 10 years compared to that of the Saudis. Conclusions: A definite declining trend in the incidence of CL was observed in al Hassa. Further studies are warranted to assess whether special public health measures are needed for better control of CL in expatriate populations in Saudi Arabia.

RIESZ IDEMPOTENT AND BROWDER'S THEOREM FOR ABSOLUTE-(p,r)-PARANORMal OPERATORS

引用

Acta Mathematica Scientia 2012年第6期32卷 2259-2264页

作者： salah Mecheri Department of Mathematics College of ScienceTaibah UniversityP.O.Box 30002Al Madinah Al MunawarahSaudi Arabia

An operator T is said to be paranormal if ｜｜T^2 x ｜｜〉｜｜Tx｜｜^2 holds for every unit vector x. Several extensions of paranormal operators are considered until now, for example absolute-k-paranormal and p-paranormal introduced in [10], [14], respectively. Yamazaki and Yanagida [38] introduced the class of absolute-（p, r）-paranormal operators as a further generalization of the classes of both absolute-k-paranormal and p-paranormal operators. An operator T ∈ B（H） is called absolute-（p, r）-paranormal operator if ｜｜｜T｜p｜T^＊｜^rx｜｜^r 〉｜｜｜T^＊｜^rx｜｜p＋r for every unit vector x ∈ H and for positive real numbers p 〉 0 and r 〉 0. The famous result of Browder, that self adjoint operators satisfy Browder＇s theorem, is extended to several classes of operators. In this paper we show that for any absolute-（p, r）- paranormal operator T, T satisfies Browder＇s theorem and a-Browder＇s theorem. It is also shown that if E is the Riesz idempotent for a nonzero isolated point μ of the spectrum of a absolute-（p, r）-paranormal operator T, then E is self-adjoint if and only if the null space of T -μ, N（T - μ） N（T^＊ - ^μ）.
