Educational Research and Reviews

Educ. Res. Rev.

In this research, we aim to develop a 5-point likert scale and use it in an experimental application by performing its validity and reliability in order to measure the will perception of teenagers and adults. With this aim, firstly the items have been taken either in the same or changed way from various scales and an item pool including 61 items highly comprimising significant and probable testing areas have been formed. This item pool has been... Read more

Anticonceptive, estrogenic and antiestrogenic potentials of methanol extract of Garcinia kola seed in rodents

Journal of Medicinal Plants Research

J. Med. Plants Res.

The anticonceptive, estrogenic and antiestrogenic potential of methanolic extract of Garcinia kola seed in rodents was investigated. The anti-conceptive effect of extract showed that the extract dose-dependently protected female mice and rats from conception for two to three gestational periods. Changes observed in the length and weights of pups were not statistically significant relative to control. There were no abnormalities observed in the pups... Read more

Subsoil chemical amelioration and crop yields under continuous long-term no-till in a subtropical Oxisol

African Journal of Agricultural Research

Afr. J. Agric. Res.

Long-term no-till with shallow fertilizer input results in a chemical enriched topsoil but has minor effect of subsoil. The sub-optimal use of water and mobile nutrients stored in the subsoil layers is a frequent limiting factor to crop grain yield in tropical acid soils. This study aim assesses the corn and soybean grain yield response to gypsum combined with lime surface input as a tool for subsoil chemical quality improving. A Brazilian... Read more
