Impact of electron-beam irradiation combined with shellac coating on the suppression of chlorophyll degradation and water loss of lime fruit during storage
Ratchagon Pongsri,Sukanya Aiamla-or,Varit Srilaong,Apiradee Uthairatanakij,Pongphen Jitareerat +4 more
TL;DR: In this paper, the effect of electron-beam (E-beam) irradiation and shellac coating on chlorophyll degradation and qualities in lime fruit was studied and the results imply that shellac coatings combined with E-beam irradiation is an alternative approach to delay the degradation and maintain the quality of lime fruit.

A specific method for determination of total ascorbic acids in urine by the α,α-dipyridyl method
TL;DR: Application of the α,α-dipyridyl method for determination of ascorbic acid in urine is described and ferrous ion in urine samples, which theoretically interferes with the method, was removed by a combination of Na 2 HPO 4 and H 3 PO 4.
Journal ArticleDOI
Analysis of arterial and cerebral venous blood from the rabbit
TL;DR: Findings with respect to glucose, lactic acid, and keto-acids which are in line with those already established in other species are described, and initial studies of amino acids, indole compounds, ascorbic acid and purines are described.

Some biochemical aspects of bracken ‘POISONING’ in the ruminant animal. I.—Vitamin factors
F. E. Moon,M. A. Raafat +1 more
TL;DR: Measurements of blood prothrombin time suggested that no deficiency of vitamin K is involved in the production of this disease, but low body-reserves of vitamins A and C were found in experimental sheep which had died with bracken ‘poisoning’.
