Sieving is a simple and low cost process, and has the ability to measure relatively coarse particles up to several centimeters in size, and these are some of the reasons that sieving is still in use ...

Genomic sieve analysis of these so-called "breakthrough" SARS-CoV-2 infections in COVID vaccine trials is a critical tool to identify viral mutations associated with vaccine failure and to predict how ...

Particle analysis is a crucial step in the quality control of bulk materials and is performed in laboratories worldwide. The methods used have usually been established for years and are rarely ...

Assessment of vaccine efficacy as a function of the similarity of the infecting pathogen to the vaccine is an important scientific goal. Characterization of pathogen strains for which vaccine efficacy ...

Careful cutting of the hypocotyl of Ricinus communis L. seedlings led to the exudation of pure sieve-tube sap for 2—3 h. This offered the possibility of testing the phloem-loading system qualitatively ...

RECENTLY, Harris and Jowett have discussed an inherent shortcoming of the electronic counter which is able to count only those particles above a certain threshold size 1. Thus a substantial portion of ...

Our two labs help process and analyze sediment samples and sediment cores collected from terrestrial, lake, and marine environments. We perform chemical and physical analyses on sediments and other ...

DUBLIN--(BUSINESS WIRE)--The "Europe Molecular Sieves Market - Segmented by Type, End-user Industry, and Geography - Growth, Trends, and Forecast (2018 - 2023)" report has been added to ...

SILVER SPRING, Md. - As concern has grown over COVID-19 variants and their implications for how well COVID-19 vaccines will protect against the virus, researchers have proposed a method to examine ...
