On the functions ${\rm Ci}(x,y)$ and ${\rm Si}(x,y)$

Abstract: FUNCTIONS Ci{x,y) AND Si\x\ y)*> TAMOTSU TSUCHIKURAMr. Gennόsuke Hara has introduced the following functions 1 *:where LF 0 (2/, 2y) a ^d U 1 (2f>2ji) are LcmmeΓs fmctions of order zero and one respectively.In this note we shall establish some relations concerning these functions, especially Hara's function γ(j/)* £) FORMULA ( 1). If ftv > -1, then (sd = TMT) ί 1 -Z \?Ji k dπ 0) cos PROOF. We shall prove the first part. (! ε sto "> cos " + '' •* -*) Received May 1, 1946. 2) In the sequel, we adopt the notation… Show more

“…Cystine was chosen for study since the S-S bonds joining peptide chains are quite labile and since results from chemical studies have indicated that hydrogen sulfide (1, 26,27) and sulfhydryl-containing compounds (3, 18,25) increase in fishery products undergoing spoilage.…”

“…It was considered of value in the present study, therefore, to find some substance in fish tissue that could be utilized in a critical experiment to evaluate the approach to spoilage indices proposed here. Cystine was chosen for study since the S-S bonds joining peptide chains are quite labile and since results from chemical studies have indicated that hydrogen sulfide (1, 26,27) and sulfhydryl-containing compounds (3, 18,25) increase in fishery products undergoing spoilage.…”
