We consider the punctured plane with volume density $|x|^\alpha$ and perimeter $|x|^\beta$. show that centred balls are uniquely isoperimetric for indices $(\alpha,\beta)$ which satisfy conditions $\alpha-\beta+1>0$, $\alpha\leq 2\beta$ $\alpha(\beta+1)\leq\beta^2$ except in case $\alpha=\beta=0$ corresponds to classical inequality.

Early, lesion-based models of language processing suggested that semantic and phonological processes are associated with distinct temporal and parietal regions respectively, with frontal areas more indirectly involved. Contemporary spatial brain mapping techniques have not supported such clear-cut segregation, with strong evidence of activation in left temporal areas by both processes and dispu...

inthis paper, the main aim is to introduce the class $mathcal{u}_p(lambda,alpha,beta,k_0)$ of $p$-harmonic mappings togetherwith its subclasses $mathcal{u}_p(lambda,alpha,beta,k_0)capmathcal {t}_p$ and $mathcal{u}_p(lambda,alpha,beta,k_0)capmathcal {t}_p^0$, andinvestigate the properties of the mappings in these classes. first,we give a sufficient condition for mappings to be in $mathcal{u}_p(l...

previous studies have shown that when people enter a new cultural environment which is different from their own culture, they face a lot of problems to adapt themselves with the new environment. this may result in intense dissatisfaction with the new situation. the data for the present study were collected from a randomly-selected sample of 300 people, from among a population of 1100, through q...

OBJECTIVE To compare the effectiveness of beta lactam monotherapy versus beta lactam-aminoglycoside combination therapy in the treatment of patients with fever and neutropenia. DATA SOURCES Medline, Embase, Lilacs, the Cochrane Library, and conference proceedings to 2002. References of included studies and contact with authors. No restrictions on language, year of publication, or publication ...

the results of many studies suggested possible relationship between polymorphism at codons 16 and 27 and development of tolerance to beta-2 adrenoceptor agonist responses as well as disease severity in asthmatic patients. this study was designed to evaluate the effect of polymorphism of beta2 adrenoceptors on response to salmeterol and fluticasone (as inhaled seretide). sixty-four patients with...

introduction: hypoparathyroidism (hpt) is an irreversible but preventable disorder caused by an iron overload which can be considered a typical complication in patients with beta-thalassemia major. patients and method: parathyroid function was evaluated in 130 patients in qom, iran, who suffered from beta-thalassemia major. their serum ferritin levels were checked for monitoring of chelation th...

background: members of the eukaryotic hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. in the present study, the expression of hsp90 alpha and hsp90 beta genes in xenopus...

conclusions despite of high resistance of p. aeruginosa, the resistance rate of p. aeruginosa strains isolated from children in the current study was not high. then accurate prescription of antibiotics can decrease the speed of resistance creation. background the first report of pseudomonas aeruginosa (p. aeruginosa) carbapenem resistant strains, and especially the metallo-beta-lactam (mbl) pro...
