Some Further Experiments on Bimolecular Lipid Membranes

In the earlier experiments it was established that a bilayer of pure egg phosphatidyl choline containing less than 50 per cent by volume of n-decane had a capacitance of 0.38 /ff/cm2 , this value being independent of applied voltage up to at least 50 my and independent of frequency between 200 and 5 X 106 cs. It was also unaffected by the nature and concentration of the surrounding electrolyte ...

Some Ethical Reflections on In Vitro Fertilization

In vitro fertilization is becoming a pressing issue in contemporary societies. The article considers it starting from the Polish debate but takes up its broader anthropological and ethical aspects. Dealing with the latter, it also employs some acute remarks from “Dignitas Personae.” Finally it considers an approach to in vitro against the background of “European Convention on Bioethics.” In its...

Further results on odd mean labeling of some subdivision graphs

Let G(V,E) be a graph with p vertices and q edges. A graph G is said to have an odd mean labeling if there exists a function f : V (G) → {0, 1, 2,...,2q - 1} satisfying f is 1 - 1 and the induced map f* : E(G) → {1, 3, 5,...,2q - 1} defined by f*(uv) = (f(u) + f(v))/2 if f(u) + f(v) is evenf*(uv) = (f(u) + f(v) + 1)/2 if f(u) + f(v) is odd is a bijection. A graph that admits an odd mean labelin...
