The diurnal rhythm in the urinary excretion of 17-ketosteroids and neutral reducing lipids has been reported by Pincus. 1) On the other hand the diurnal variation of circulating eosinophils in normal subjects has been studied by Rud,2) Bonner3) and others.4) 5) The characteristic feature in diurnal rhythm of urinary steroids is an increase in the morning especially after awakening. Meanwhile th...

The electrocatalytic ability of the iron-substituted crown-type polyoxometalate (POM) Li4K16[P8W48O184Fe16(OH)28(H2O)4]66H2O2KCl (P8W48Fe16) towards the reduction of both nitrite and hydrogen peroxide reduction has been studied in both the solution and immobilized states for the POM. P8W48Fe16 was surface immobilised onto carbon electrode surfaces through employment of the layer-bylayer techn...

Regular almost periodicity in compact minimal abelian flows was characterized for the case of discrete acting group by W. Gottschalk and G. Hedlund and for the case of 0-dimensional phase space by W. Gottschalk a few decades ago. In 1995 J. Egawa gave characterizations for the case when the acting group is R. We extend Egawa’s results to the case of an arbitrary abelian acting group and a not n...

The problem of impostor dataset selection for GMM-based speaker verification is addressed through the recently proposed data-driven background dataset refinement technique. The SVM-based refinement technique selects from a candidate impostor dataset those examples that are most frequently selected as support vectors when training a set of SVMs on a development corpus. This study demonstrates th...

The crystal structure of the title compound, C(7)H(14)NO(2) (+)·Cl(-), was reported previously [Chacko, Srinivasan & Zand (1975 ▶). J. Cryst. Mol. Struct.5, 353-357] from Weissenberg photographic data with R = 0.113. It has now been redetermined, providing a significant increase in the precision of the derived geometric parameters, viz. mean σ(C-C) = 0.003 Å in the present work compared with 0....

decreasing water resources has made optimum water allocation in agriculture essential. planning optimum irrigation and crop production function considering accessible water and growing stage is an efficient approach to increase water productivity. studies have applied this approach to maximize crop production using the fao crop production method introduced in 1979. however, the fao introduced a...

relations between the third world countries in different parts of asia and africa during the 19th and 20th centuries, to a great extent, were influenced by the presence and policies of colonial powers. thus, for a better understanding of roots of disputes and issues existing between these countries concerning frontiers, disputed islands, political and prejudicial tensions, we need to study past...
