The COVID-19 pandemic presents potential mental health challenges, and the American Orthodox Jewish population has been particularly affected by the virus. The current study assessed the impact of the pandemic and explored the relationships between exposure, religiosity, and distress in a sample of n = 419 American Orthodox Jews. Results indicated high levels of exposure, concern, and compliance with medical guidelines; however stress was generally low and we found evidence for positive impact. Direct exposure correlated with higher religiosity. Positive religious coping, intrinsic religiosity and trust in God strongly correlated with less stress and more positive impact, while negative religious coping and mistrust in God correlated with the inverse. While the study is limited by its design, findings highlight that for some, faith may promote resilience especially during crisis.

This paper describes laminar fluid flow through a three-dimensional elastomeric microstructure formed by two microfluidic channels, fabricated in layers that contact one another face-to-face (typically at a 90 degree angle), with the fluid flows in tangential contact. There are two ways to control fluid flow through these tangentially connected microchannels. First, the flow profiles through the crossings are sensitive to the aspect ratio of the channels; the flow can be controlled by applying external pressure and changing this aspect ratio. Second, the flow direction of an individual laminar stream in multiphase laminar flow depends on the lateral position of the stream within the channel; this position can be controlled by injecting additional streams of fluid into the channel. We describe two microfluidic switches based on these two ways for controlling fluid flow through tangential microchannels and present theoretical arguments that explain the observed dependence of the flow profiles on the aspect ratio of the channels.
