Composting is a useful waste treatment for environmental problem, but composting experiment is challenging due to large-scale requirement. Thus, laboratory-scale reactor is of interest for composting experiment. The capability of laboratory-scale reactor to simulate large-scale composting was determined by assessing the quality of produced compost via germination index.

In everyday life, nature has given us countless useful medicinal plants. Among the common plants in Vietnam, the custard apple (Annona squamosa L.) has not been mainly used as a fruit but also traditionally as a medicine. However,studies on morphological characteristics remain limited in Vietnam as well as around the world. Determine the morphological and microscopic characteristics, and physicochemical features of A. squamosa leaves.

This study focuses mainly on the normal stresses that are caused by applied forces. As a case study, the present work aims at investigating the bi-dimensional contact mechanics of wavy cosinusoidal anisotropic finite planes. To achieve this objective, results on the displacement and stress component are first calculated with the help of the Lekhnitskii formalism.
