Background The left ventricular (LV) ejection fraction (EF) is a crucial parameter for the diagnosis and therapeutic management of heart failure. Due to its wide availability and its comprehensive use, echocardiography (EC) is the standard method for the assessment of the LV function in clinical routine. As fundamental clinical decisions, e.g. initiation of medical heart failure therapy or impl...

we find recursive formulae for the number of perfect matchings in a graph g by splitting g into subgraphs h and q. we use these formulas to count perfect matching of p hypercube qn. we also apply our formulas to prove that the number of perfect matching in an edge-transitive graph is , where denotes the number of perfect matchings in g, is the graph constructed from by deleting edges with an en...

The rapid identification of Staphylococcus aureus from positive blood cultures provides important clinical and therapeutic information. Using criteria based on direct Gram stain characteristics, an experienced microscopist was able to distinguish S aureus from other staphylococci isolated from BacT/ALERT blood culture bottles with an overall sensitivity of 89% and specificity of 98%. Furthermor...

Introduction The purpose of this lecture is to introduce you to terminology used in microbiology. The lecture will: 1. cover different classification schemes for grouping bacteria, especially the use of the Gram stain 2. describe the different types of bacteria 3. discuss bacterial structure and the function of the different bacterial components 4. discuss the distinguishing characteristics of ...

The most effective way to express the mathematical and physical research results is by using formulas. Our article contains formulas that were biggest contributors development of technical, physical, sciences. can be applied in different areas. In this article, we will show how calculate an orbit a miniature satellite based on Law Gravity. For calculations online recording results, are MATLAB s...
