For compact Hausdorff admissible right topological (CHART) group G, we prove w(G)=πχ(G). This equality is well known for groups. implies the criteria metrizability of CHART groups: if G first-countable (2013, Moors, Namioka) or Fréchet Glasner, Megrelishvili), has countable π-character (2022, Reznichenko) then metrizable. Under continuum hypothesis (CH) assumption, a sequentially Namioka's theo...

Water pH and active ingredient concentration are two of the most important variables to consider in the manufacturing process of fungicides. If these variables do not meet the required standards, the quality of the product may be compromised and lead to poor fungicide performance when water is used as the application carrier, which is in most cases. Given the correlation between the variable...

Background Frequent blood transfusion is often associated with iron overload. Proper use of iron chelators to treat iron overload requires an accurate measurement of iron levels. Magnetic resonance T2-star (T2* MRI) can measure iron level in the heart and liver. Our goal was to see whether an association exists between serum ferritin level and T2* MRI in patients with major beta thalassemia. ...
