This paper describes the design of a ventilation system to be paired with a carbon capture system. The ventilation system utilizes the geometry of the George C. Wallace tunnel, located in the City of Mobile, Alabama, USA to capture and redirect emissions to a direct air capture (DAC) device to sequester 25% of the total CO2 mass generated from inside the tunnel. The total CO2 mass rate for the westbound traffic between the week-day hours of 7 a.m. and 6 p.m. has been estimated between 2,300 to 3,000 lbs./hr. By sequestering these emissions, the overall surrounding air quality was shown to be improved to a level that mirrors that from the pre-US industrial era of 270 ppm.

It is now recognized that nanoscale particulate matter(pM)represents a substantial health hazard for our society,including pM from restaurant *** this study,we explored the use of a transient pulsed plasma in conjunction with an applied DC bias to treat oil aerosols that closely resemble restaurant(i.e.,charbroiler)smoke *** polyaromatic olefin pAO-4 and soybean oil,we found that a three-order-of-magnitude reduction in particulates(i.e.,99.9%remediation)could be achieved with this ***,the plasma discharge was produced in a 4-in.-diameter cylindrical reactor with a 5-10 ns high voltage(30 kV)pulse generator together with applied DC bias voltages up to 10 *** distribution of nanoparticle sizes was measured using a scanning mobility particle sizer(SMpS)with diameter centered around 225 ***,the main mechanism of remediation occurs in a two-step process in which the oil nanoparticles are first ionized by the free electrons and free radicals in the plasma and then the charged particles are swept out to the sidewalls of the reactor by the applied DC *** believe this general approach opens up new degrees of freedom in the design of electrostatic oil aerosol pollution control devices.

HIV已不再占据头条新闻。这主要是因为抗逆转录病毒药物的成功开发已将HIV病毒感染导致的艾滋病（AIDS）转化为一种慢性的可控制的疾病。然而。当前在全世界大约0．367亿名HIV感染者中，仅约一半的人能够获得控制这种病毒所需的药物。与此同时。新的HIV感染率持续保持在非常高的水平，这突出强调了需要开发一种预防性疫苗。然而，几十年来。
