Purification and Properties of Bacteriophage f2 Replicase
… infection of E. coli with the RNA bacteriophage f2. Studies on the RNA replicase of the distantly-related bacteriophage Q3 have established the feasibility of using a simplified assay for replicase activity based on the ability of the enzyme to polymerize GTP in the presence of polycytidylic acid …

Quantitative Trait Loci Analysis of Low Temperature Responses in Grapevine F2 Population
… using quantitative trait loci analysis (QTL). An F2 population developed by selfing a single F1 from a cross between American species <em>Vitis riparia</em> and a hybrid grapevine Seyval, was used to conduct QTL analysis for subzero temperature tolerance. The low temperature exotherms (LTE) …

Exclusive Pomeron- and Odderon induced photoproduction of omega- and f2 mesons at HERA
The topics of this thesis are the analyses of exclusive photoproduction of $omega$- and $f_{2}$-mesons at mean $gp$ centre of mass energies of $langle Wangleapprox 200$ GeV at HERA. The former process is thought to be induced by photon-Pomeron interactions, and its cross section is measured to be …

Reciprocal Differences in F2 and F3 Nellore-Angus Halfblood Steers for Growth and Health Traits
Nellore-Angus halfblood reciprocal F2 and F3 steers (n = 372) produced in the Texas A&M AgriLife Research McGregor Genomics project were evaluated for weight and growth through different stages of life, including after a standardized bovine viral diarrhea virus (BVDV) challenge. The F2 steers were …

The influence of surface tension on F2-Bubble Morphology at detachment from carbon electrodes in KF-2HF molten fluoride salt
Molecular F2 and H2-bubbles were generated electrochemically on amorphous carbon electrodes in KF-2HF molten salt to study the effect of surface tension (ϒ) on the profile of a bubble. F2 is used for the purification and enrichment of fuel in the nuclear industry. Its generation is energy-intensive …

Small stem assay for chestnut blight resistance in segregating half-sib and full-sib families of F2 and backcross hybrid chestnut trees
… 2017 (Gentner 2018). In 2018, an additional 391 F2 hybrid chestnut seedlings were screened in a randomized complete block design. All seedlings were inoculated with the chestnut blight causal organism Cryphonectria parasitica when stem diameters were greater than 4mm. The 2017 trial recorded the …
