Solution 31P-Nuclear Magnetic Resonance (NMR) is an analysis technology which has been an effective means for the analysis of environmental organic phosphorus. However, the method is rarely applied in the study of wetlands so that the corresponding researches about wetland sediment sample preparation method also very deficient. The present study was aimed(More)
BACKGROUND The perforator flap has become a very useful reconstructive means of soft tissue defect of extremities. The perforator flap from the inguinal region has advantages that include the ability to cover a large area with little donor site morbidity and provision of suitable thickness for reconstruction. METHODS From July 1, 2005 to June 30, 2007, 10(More)
With the development of oilfields, the problem of eccentric wear between casing and sucker rod in rod-pumped wells operation is more and more severe. Investigations on the eccentric wear show that the abrasion of sucker rod joint is more serious than the sucker rod itself. A new method of producing the Ni-base composite coating that contains nano-diamond(More)
The title compound, (C(10)H(10)N(2))(2)[Fe(C(2)O(4))(2)(H(2)O)(2)](C(2)HO(4))(2), appears to be a modular associate consisting of a complex anion containing bivalent Fe as the central atom, a bridging hydrogen oxalate anion and a diprotonated 4,4-bipyridine acting as the counter-cation. The Fe(II) ion in the complex anion occupies a position on a centre of(More)
The composite tissue flap of the descending genicular vessels with the adductor magnus tendon is a newly developed, reliable method to repair the Achilles tendon and relevant skin defects. The aim of this study was to evaluate the anatomy of the adductor magnus tendon-descending genicular artery bone flap, and the feasibility and value for the repair of the(More)
