Study of influence of cold rolling and annealing on ultimate tensile strength of AA2024 alloy using Box-Behnken experimental design
This study investigates the effects of thermo-mechanical processing parameters, specifically cold rolling and annealing, on the ultimate tensile strength (UTS) of AA2024 alloy, employing a Box-Behnken experimental design. The deformation during cold rolling, the annealing temperature, and the time annealing were varied to evaluate their individual and combined effects on the UTS.

Development of a cold plug valve with fluoride salt
The final goal of the work is to provide useful recommendations and guidelines for the design of a cold plug for the emergency draining system of a molten salt reactor. Some numerical thermal simulations were performed with ANSYS mechanical (Finite Element Method) to be compared with results of the experiments and to make extrapolations for a new component to be used in a reactor.

Effects of cold joints on the structural behaviour of polyurethane rigid foam panels
In this study, using a unique pneumatic pressure testing rig, bending tests are conducted on the two types of rigid polyurethane panels. The panels are categorized based on the existence of construction cold joints (seams) as S (Seamless) type and TS (Transverse Seams) type.

Preparation and characterisation of attenuated cold-adapted influenza A reassortants derived from the A/Leningrad/134/17/57 donor strain

Preparation and characterisation of attenuated cold-adapted influenza A reassortants derived from the A/Leningrad/134/17/57 donor strain presents the assay was capable of detecting interference where the infectivity ratio for A/Len/17 and A/Beij/32 was 1:7. Progeny viruses were characterised genetically by amplification of defined regions within each of the six internal genes by PCR and identification of the products by restriction enzyme analysis.
