Context. Insight into the conditions that drive physics and chemistry in interstellar clouds is gained from determining abundance charge state of their components. Aims. We propose an evaluation C60:C60+ ratio diffuse translucent exploits electronic absorption bands so as not to rely on ambiguous IR emission measurements. Methods. The determined by analyzing archival spectra literature data. In...
Background: Increasing demand for blood and blood products mostly due to increased individual access to health care services rises the concerns over lack of adequate amounts of blood products. It also can impose additional costs to blood transfusion centers and may increase transfusion-related complications. We aimed to investigate the impact of the Iranian Blood Transfusion Organization (IBTO)...
In this paper we describe block algorithms for the reduction of a real symmetric matrix to tridiagonal form and for the reduction of a general real matrix to either bidiagonal or Hessenberg form using Householder transformations. The approach is to aggregate the transformations and to apply them in a blocked fashion, thus achieving algorithms that are rich in matrix-matrix operations. These red...
