An alternative to the sickling test.

An assessment of Sickledex as an alternative to the sickling test.

Cloze-Elide Test as an Alternative Test Method: Linking Personality Types to Test Method Performance

More innovative test methods may measure language learners’ test performance more accurately, contributing to much fairer decisions. This study examined Iranian language learners’ performance on cloze-elide test as an innovative, integrative test method. It specifically focused on investigating whether personality types correlated with their performance and whether personality types could predi...

Spot test for detection of sickling hemoglobin.

We describe a simple, noninstrumental procedure for detecting hemoglobin S in samples of blood on filter paper, with use of small volumes of reagents. The method depends on the differential solubilities of reduced sickling and nonsickling hemoglobin in phosphate solutions (1, 2) or Sickledex reagent’ and the apparent solubilizing effect of urea on reduced hemoglobin S (3). The color of paired p...

Development of an alternative to the olsen test for determining corn plant-available phosphorus in calcareous soils

In this research, several chemical extractants and modified Olsen methods were studied in 25 surface-calcareous soils (0-30 cm) for determining available phosphorus (P) for corn (Zea mays L.) plant. In this experiment, the highest correlation was obtained between extracted P by Olsen and Colwell methods (NaHCO3-extractable P) and dry weight of corn shoot (r =0.67 and 0.75, p
