Fear and depressive symptoms amid COVID-19: A cross-sectional pilot study among adult population in Bangladesh.

Background: Fear is a primary emotional reaction to the deadly coronavirus disease which might be an associated factor for developing depressive symptoms. This study aimed to assess the level and associated factors of fear and depression amid the COVID-19 pandemic among the adult population of Bangladesh.

Methods: After providing informed consent, 1050 participants completed the cross-sectional online survey tool.

A diffusion model for drying of a heat sensitive solid under multiple heat input modes.

To obtain optimal drying kinetics as well as quality of the dried product in a batch dryer, the energy required may be supplied by combining different modes of heat transfer. In this work, using potato slice as a model heat sensitive drying object, experimental studies were conducted using a batch heat pump dryer designed to permit simultaneous application of conduction and radiation heat. Four heat input schemes were compared: pure convection, radiation-coupled convection, conduction-coupled convection and radiation-conduction-coupled convection.
