Characterization of coliphage PR772 and evaluation of its use for virus filter performance testing.

Coherent soft X-ray diffraction imaging of coliphage PR772 at the Linac coherent light source

Single-particle diffraction from X-ray Free Electron Lasers offers the potential for molecular structure determination without the need for crystallization. In an effort to further develop the technique, we present a dataset of coherent soft X-ray diffraction images of Coliphage PR772 virus, collected at the Atomic Molecular Optics (AMO) beamline with pnCCD detectors in the LAMP instrument at t...

Physical characterization of icosahedral virus ultra structure, stability, and integrity using electrospray differential mobility analysis.

We present a rapid and quantitative method to physically characterize the structure and stability of viruses. Electrospray differential mobility analysis (ES-DMA) is used to determine the size of capsomers (i.e., hexons) and complete capsids. We demonstrate how to convert the measured mobility size into the icosahedral dimensions of a virus, which for PR772 become 68.4 nm for vertex-to-vertex, ...

HEPA Filters specifications in two standards, ASME AG-1 & DOE for using in Tehran Research Reactor (TRR)

HEPA filters serve as important safety device to protect personnel as well as the public and environment from the radiation effects exist in the air, so they are vital devices in the event accidents. DOE provides directions through the use of two technical standards, 3020 and 3025, including QA requirements for the procurement, packaging, shipping and storage of HEPA filters and also provides d...

The use of dried whole blood absorbed on filter-paper for the Evaluation of Diphtheria and Tetanus Antitoxins in Mass Surveys

Performance evaluation of groundwater drainage in two types of PP450 synthetic filters and natural filtering in Sugarcane Farms: A Case Study of Salman Farsi Cultivation and Industry

Sand coverings account for a large part of the cost of a project. The purpose of this study is to evaluate the performance of different coatings for filtration of underground drains and reduce the cost of cornfield farms. The experiments were carried out in farm in Salman Farsi. The subsoil drainage was fitted to each test piece with a length of 120 meters, a diameter of 100 mm, and a distance ...
