it has been proved that ultrasonic energy can considerably increase the amount of oil recovery in animmiscible displacement process. although many studies have been performed on investigating theroles of ultrasonic waves, based on the best of our knowledge, little attention has been paid to evaluatewave attenuation parameter, which is an important parameter in the determination of the energydel...

We report initial NMR studies of (i) xenon gas diffusion in model heterogeneous porous media and (ii) continuous flow laser-polarized xenon gas. Both areas utilize the pulsed gradient spin-echo (PGSE) techniques in the gas phase, with the aim of obtaining more sophisticated information than just translational self-diffusion coefficients--a brief overview of this area is provided in the Introduc...

It has been proved that ultrasonic energy can considerably increase the amount of oil recovery in an immiscible displacement process. Although many studies have been performed on investigating the roles of ultrasonic waves, based on the best of our knowledge, little attention has been paid to evaluate wave attenuation parameter, which is an important parameter in the determination of the energy...

1. Entopy and viral packing. In the very first lecture, we learned how to do approximate integration by approximating curves as lines. We estimated how much energy it takes to pack the φ29 genome. As a reminder, the experimental setup is shown in Fig. 1a. A bead in an optical trap is connected to the φ29 DNA. The viral capsid is attached to an immobilized bead. The packing motor works to pack t...

We have developed a miniaturized bead-beating device to automate nucleic acids extraction from Gram-positive bacteria for molecular diagnostics. The microfluidic device was fabricated by sandwiching a monolithic flexible polydimethylsiloxane (PDMS) membrane between two glass wafers (i.e., glass-PDMS-glass), which acted as an actuator for bead collision via its pneumatic vibration without additi...

The initial rate of platelet aggregation induced by adenosine diphosphate and thrombin correlated with the number of platelets retained when samples of citrated blood from the same normal donors were passed through glass bead columns. The results support the view that the glass bead column method of measuring platelet ;adhesiveness' is influenced by platelet aggregation.
