We measured the Dk (oxygen permeability) of one specific hydrogel contact lens material (phemfilcon A, nominally 38% water content and ionic) by use of the conventional single chamber polarographic technique at 35 degrees C. When corrected for the boundary and edge effect, Dk was found to be 13 x 10(-11) cm2 ml O2/s ml mm Hg.

On Representing ‘True-in-L’ in L [PDF]
Philosophia, 1975 Given Tarski’s familiar treatment of the semantic paradoxes, no formal language can adequately represent its own truth-concept.1 But natural languages do, apparently, express their own truth-concepts and this fact alone has been enough to motivate some to seek alternative treatments of the paradoxes.

l‐Alanyl‐l‐Leucyl‐l‐Tyrosyl‐l‐Leucyl‐l‐Valin
Justus Liebigs Annalen der Chemie, 1960AbstractDas in der Phenylalaninkette des Insulins vorkommende Pentapeptid l‐Alanyl‐l‐leucyl‐l‐tyrosyl‐l‐leucyl‐l‐valin wurde aus Carbobenzoxy‐l‐alanyl‐l‐leucin und l‐Tyrosyl‐l‐leucyl‐l‐valin synthetisiert und sein säurehydrolytischer und enzymatischer Abbau untersucht.

Triterpene glycosides ofHedera canariensis. I. Structures of glycosides L-A, L-B1, L-B2, L-C, L-D, L-E1 1, L-G1, L-G2, L-G3, L-G4, L-H1, L-H2, AND L-I1 from the leaves ofHedera canariensis [PDF]
Chemistry of Natural Compounds, 1996 From the leaves of Algerian ivyHedera canariensis Willd. (fam. Aralaceae) we have isolated 13 triterpene glycosides: the 3-O-α-L-arabinopyranosides of oleanolic acid (A), of echinocystic acid (B1), and of hederagenin (B2); the 3-O-[O-α-L-rhamnopyranosyl-(→2)-α-L-arabinopyranoside]s of oleanolic acid (C), of echinocystic acid (D), and of hederagenin (E1)

Synthesis of L-leucyl-L-isoleucine and L-isoleucyl-L-leucine [PDF]
Russian Journal of Organic Chemistry, 2015 New preparative procedures were developed applying tert-butoxycarbonyl or trifluoroacetyl protection of amino groups in the synthesis of L-leucyl-L-isoleucine and L-isoleucyl-L-leucine.

Using one of the models of Gell-Mannet al. the intermediate vector meson mass is estimated by using the upper limit for the decay of theKLEmphasis>/0 meson into a lepton pair. This mass turns out to be very large. Therefore only the leading terms are taken into account.
