Investigations of recalcitrant, or desiccation-sensitive, seeds have as yet failed to identify the causes of this phenomenon. Experiments with Guarea guidonia (L.) Sleumer (American muskwood) were initiated to determine the effects of desiccation on the physiology and biochemistry of the seeds of this tropical tree species. Seeds were air-dried at room temperature for 7 days. At intervals, germ...

Karl Pearson played an enormous role in determining the content and organization of statistical research in his day, through his research, his teaching, his establishment of laboratories, and his initiation of a vast publishing program. His technical contributions had initially and continue today to have a profound impact upon the work of both applied and theoretical statisticians, partly throu...

A solution of urea, sulphur dioxide and sodium salicylate in methanol is proposed as the solvent in the Karl Fischer titration, with a separate iodine solution as titrant. Comparison of the performance of this solvent with that of some commercial reagents shows that it is has distinct advantages for use with amine samples.

This special volume of the Journal of Economic Theory honors Karl Shell, the journal’s founding editor, on the occasion of his 65th birthday. The contributions to the volume are from Karl’s students or co-authors. Karl’s generosity and intellect have touched our lives profoundly. His keen sense of what matters most in economic theory has shaped our own research, and has influenced the entire ec...

Residual moisture content plays a significant role in assessing the stability of veterinary vaccines. Analysis of water amount is often a critical parameter, which determines the quality of product, its appearance as well as the expiration date. The aim of the study was to validate a coulometric Karl Fisher method for practical use in the national monitoring of veterinary vaccines market. Immun...

This review article aims to discuss and analyze the background and findings regarding Fisher-Mendel Controversy in Genetics and to elucidate the scientific argument and intellectual integrity involved, as well as their importance in a fair society, and the lesson of Western falls as learned. At the onset of this review, the kernel of Mendel-Fisher Controversy is dissected and then identified. T...

Örnekleme dağılımlarının temelini oluşturan Ki-kare, t ve F dağılımlarını sırasıyla Karl Pearson, William Sealy Gosset Ronald Aylmer Fisher istatistik bilimine kazandırmıştır. normal dağılım göstermeyen veriler için o dönemde yaptığı çalışmalar sonucu Ki-kare dağılımını elde etmiştir. Sonraki yıllarda Fisher, dağılımı üzerine ile serbestlik derecesinde bir düzeltme yapmıştır. Bu durum Pearson t...
