ABSTRACT Kinematic lensing (KL) is a new cosmological measurement technique that combines traditional weak (WL) shape measurements of disc galaxies with their kinematic information. Using the Tully–Fisher relation, KL breaks degeneracy between intrinsic and observed ellipticity significantly reduces impact multiple systematics are present in WL. We explore performance given instrument capabilit...

‎In this article‎, ‎we discuss about solvability of infinite systems of singular integral equations with two variables in the Banach sequence space $C(I times I‎, ‎c)$ by applying measure of noncompactness‎ and Meir-Keeler condensing operators‎. By presenting an example, we have illustrated our results‎. ‎For validity of the results we introduce a modified semi-analytic method in the case of tw...

The synthesis and single-crystal X-ray structure determination of the title compound [(bipy) , Pb(0 ,CMe) (O ClO )] (1) and [(bipy) Pb(ClO ) ] (2) is described. Compound (I) crystallizes in the triclinic space group P1(2), a= 7.384(2), b= 12.824(3), c= 10.622(6) A, ?= 73.41(2), ?= 80.98(2), ?= 73.68(2)', Z= 2, and R =0.033 for 3408 independent reflections .Compound (2) crystallizes in the ...

nasopharyngeal angiofibroma is a relatively uncommon vascular tumor affecting adolescent males and it characteristically originates in the posterior lateral wall of the nasopharynx. primary extra-nasopharyngeal angiofibroma is very rare. here, i present a case of angiofibroma of the parapharyngeal space in a 53-year-old woman with ct and sonographic findings.

Dark matter halos that reach the HI-cooling mass without prior star formation or external metal pollution represent potential sites for of small - extremely faint Population III galaxies at high redshifts. Gravitational lensing may in rare cases boost their fluxes to detectable levels, but find even a number such objects randomly selected regions sky requires very large areas be surveyed. Becau...
