ECMO in trauma patients—Should we consider alternative cannulation sites?

Pitfalls in percutaneous ECMO cannulation

INTRODUCTION This observational report depicts typical problems of extracorporeal membrane oxygenation cannulation from a large case series of a single center. METHODS We analysed our experience with 720 consecutive patients receiving veno-venous or veno-arterial extracorporeal membrane oxygenation focusing on the spectrum of complications occurring in a subset of 159 patients treated with pe...

Should We Consider another Booster Dose of Measles Vaccine?

Background: To date, 36 years has passed since the beginning of measles vaccination; the disease is still circulating around the world, threatening lives of human beings especially in developing countries.  In recent years, we have confronted measles in previously vaccinated adults from all over the country. Objective: To find out if there is a need for changing our routine measles vaccination ...

Erythema nodosum :what should we consider about it?

Consider the Strip-Tillage Alternative

seed germination, is a new alternative to no-till in areas where poorly drained soils are dominant. Where soil moisture conditions are suitable, strip-tillage creates narrow-width tilled strips, traditionally in the fall, to increase early spring soil evaporation and soil temperature in the top 2 inches. This is particularly effective in poorly drained wet soils, where slightly raised soil stri...

2. The Problems We Consider

The Cauchy-Davenport theorem states that for any two nonempty subsets A andB of Z/pZ we have |A + B| ≥ min{p, |A| + |B| − 1}, where A + B := {a + bmod p | a ∈ A, b ∈ B}. We generalize this result from Z/pZ to arbitrary finite(including non-abelian) groups. This result from early in 2006 is independent ofGyula Károlyi’s 2005 result in [13] and uses different methods.
