State versus action orientation and compliance during the COVID-19 pandemic in Indonesia.

This study explored the roles of activity versus state direction in how Indonesians adhered to COVID-19 preventive behaviour using the theory of planned behaviour (TPB). A total of 615 participants were gathered through a web questionnaire containing 68 questions. Structural equation modelling (SEM) was used to determine the causal relationships of the latent variable construct.

Detection of the oil-producing microalga Botryococcus braunii in natural freshwater environments by targeting the hydrocarbon biosynthesis gene SSL-3.

The green microalga Botryococcus braunii produces hydrocarbon oils at 25-75% of its dry weight and is a promising source of biofuel feedstock. Few studies have examined this species' ecology in natural habitats, and few wild genetic resources have been collected due to difficulties caused by its low abundance in nature. This study aimed to develop a real-time PCR assay for specific detection and quantification of this alga in natural environments and to quantify spatiotemporal variations of wild B.
