| 1 | EXISTENCE OF MULTIPLE POSITIVE SOLUTIONS FOR SEMILINEAR ELLIPTIC SYSTEMS INVOLVING m CRITICAL HARDY-SOBOLEV EXPONENTS AND m SIGN-CHANGING WEIGHT FUNCTION显示文摘In this article, we consider a class of degenerate quasilinear elliptic problems with weights and nonlinearity involving the critical Hardy-Sobolev exponent and one signchanging function. The existence and multiplicity results of positive solutions are obtained by variational methods. | Nemat NYAMORADI Tsing-San HSU | 2014 | Acta Mathematica Scientia2014，34，2： | 4 |
| 2 | Multiple solutions for weighted nonlinear elliptic system involving critical exponents显示文摘In this paper,by using the idea of category,we investigate how the shape of the graph of h(x)affects the number of positive solutions to the following weighted nonlinear elliptic system:-div(|x|-2au)-μu|x|2(a+1)=αα+βh(x)|u|α-2|v|βu|x|b2*(a,b)+λK1(x)|u|q-2u,in,-div(|x|-2av)-μv|x|2(a+1)=βα+βh(x)|u|α|v|β-2v|x|b2*(a,b)+σK2(x)|v|q-2v,in,u=v=0,on,where 0∈is a smooth bounded domain in RN(N 3),λ,σ>0 are parameters,0μ<μa(N-2-2a2)2;h(x),K1(x)and K2(x)are positive continuous functions in,1 q<2,α,β>1 andα+β=2*(a,b)(2*(a,b)2N N-2(1+a-b),is critical Sobolev-Hardy exponent).We prove that the system has at least k nontrivial nonnegative solutions when the pair of the parameters(λ,σ)belongs to a certain subset of R2. | NYAMORADI Nemat HSU Tsing San | 2015 | Science China Mathematics2015，58，1： | 3 |
| 3 | Multiplicity of positive solutions to weighted nonlinear elliptic system involving critical exponents显示文摘This paper deals with the existence and multiplicity of nontrivial solutions to a weighted nonlinear elliptic system with nonlinear homogeneous boundary condition in a bounded domain. By using the Caffarelli-Kohn-Nirenberg inequality and variational method, we prove that the system has at least two nontrivial solutions when the parameter λ belongs to a certain subset of R. | NYAMORADI Nemat | 2013 | Science China Mathematics2013，56，9： | 3 |
| 4 | Phytochemical and biological activities of Crataegus sinaica growing in Egypt显示文摘Objective:To evaluate the cardiac activity and hepatoprotection of Crataegus sinaica (C.sinaica).Methods:All the isolated compounds were isolated by open-column liquid chromatography(CC) using sephadex LH-20 as stationary phase.Elution of the column was performed with EtOH or MeOH.The phytochemical investigation of the young stem of C.sinaica for the first time together with the leaves and flowers lead to the isolation and identification of quercetin,hyperoside,vitexin-2'-0-rhamnoside,epicatechin,procyanidin B2 and procyanidins CI.Results:Rats treated with the low and high dose of C.sinaica leaves with flowers extract showed 15%and 17%reduction in the heart rate,and reduction in the STsegment by 107%and 57%;respectively.The T-amplitude was decreased by 59%of the high dose extract.On the other hand,the young steins and leaves with flowers extracts of C.sinaica on primary culture of rat hepatocytes monolayer indicated a hepatoprotection for the total extract,ethyl acetate,butanol,and chlor of orm fractions at 100μg/mL,75μg/mL,50μg/mL,and 25μg/mL; respectively.Conclusions:The results of these chemical and biological studies suggest the use of C.sinaica growing in Egypt as a preventive drug against cardiovascular and hepatic diseases. The chemical studies suggest the use of woody young stems as a newly investigated bioactive organ.The extraction of unsaturated fatty acids from the seeds of the plant would serve as a good health and nutritive product. | Alaa Tawfeek Refaat Abdelaaty Abdelaziz Shahat Nermine Ahmed Ehsan Nemat Yassin Faiza Hammouda Elsayed Abou Tabl Shams Imbabi Ismail | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，4： | 2 |
