Effect of dietary protein-to-energy ratio on reproduction in female redclaw crayfish Cherax quadricarinatus
(2013-08-14)
The effect of eight diets with di¡erent protein-to-energy ratios (P-E ratio510, 11, 14, 16, 18, 20, 22, 24mg kJ- 1) on reproduction of female redclaw cray-fish Cherax quadricarinatus was tested under laboratory conditions. ...
Effect of pH and dye concentration on the n-octanol/water distribution ratio of phenothiazine dyes: a microelectrode voltammetry study
(Elsevier B.V., 2014-10-20)
Microelectrode voltammetry was employed to gain information on the n-octanol/water partition ratio of phenothiazine dyes. the data were obtained as a function of pH and dye concentration in aqueous solutions. All the dyes ...
The mechanism of 234U 238U activity ratio enhancement in karstic limestone groundwater
(Elsevier B.V., 1993-01-05)
Experimental etch/leach of Carboniferous Limestone gravels on a laboratory time-scale has demonstrated that 234U 238U activity ratios (AR's) greater than the radiochemical equilibrium value may be generated on short ...
Unbiased approach to diagnose the nutrient status of red guava (Psidium guajava)
(2012-09-30)
Fertilization of guava relies on soil and tissue testing. The interpretation of tissue test is currently conducted by comparing nutrient concentrations or dual ratios with critical values or ranges. The critical value ...

Human genetic studies in areas of high natural radiation. IX. Effects on mortality, morbidity and sex ratio
(Williams & Wilkins, 1978-01-01)
Sex ratio is variable and increasingly male biased at two colonies of Magellanic Penguins
(Ecological Society of America. John Wiley & Sons Inc, 2020-03)
Sex ratios are commonly skewed and variable in wild populations, but few studies track temporal trends in this demographic parameter. We examined variation in the operational sex ratio at two protected and declining breeding ...
