Study of Titanium based Composite Coatings for Resistance against Molten Aluminium Soldering on H13 Tool Steel
… is extremely reactive with the constituents of H13 die steel and has a tendency to form intermetallic layers. This chemical interaction results in sticking of molten metal to the die surface which produces defective castings and also damages the die surface. The use of thermal spray coatings …

Directed energy deposition of tool steel/copper alloy multi-material structures
… tool steel and copper alloy. Specifically, AISI H13 hot work tool steel is deposited on copper-beryllium alloy (CuBe) substrate using three deposition strategies: directly depositing H13 on CuBe (H13/CuBe), SS316L buffer (H13/SS316L/CuBe), and commercially pure nickel buffer (H13/Ni/CuBe), aiming …

Laser surface modification of steel
… of the laser surface modification of H13 tool steel using pulse laser processing mode. Initial screening experimental designs conducted lead to more optimised detailed designs. A carbon dioxide (CO2) laser system with 10.6 μm wavelength was used. In the experimental designs …

Identification of quantitative trait loci, candidate genes and diagnostic markers for Hessian fly resistance in wheat
… KASP markers for QHf.hwwg-6BS.2, H35 and H13. H13 on 6DS is a recently cloned resistance gene that originated from Aegilops tauschii; however, selectable markers were not available. In this study, KASP marker K6B_7697506 tightly linked to QHf.hwwg-6BS.2 was developed and validated in three …

Laser Directed Energy Deposition of tool steels; Investigating the heat treatment strategies and other potentialities of LDED
… of two carbon-bearing tool steels, namely AISI H13, and X35CrMoMn7-2-1 (PLASWeld Ferro55), fabricated through Laser Directed Energy Deposition (LDED). The as-built microstructure of these steels comprises a martensitic matrix with ~10 vol.% retained austenite (RA) as a consequence of …

Characterization of Hessian fly from Israel
… between Hf larvae and resistance gene H13 in wheat has recently been cloned and characterized using Hf populations from the US. Within the US, virulence is a sex-linked, recessive trait and was shown to be associated with three independent insertions that resulted in a loss of …

Investigation of flagellotropic phage interactions with their motile host bacteria
… approach. We identified three Agrobacterium sp. H13-3 genes involved in phage 7-7-1 infection. Using mass spectrometry and other analyses, we determined that the LPS profiles of strains lacking these genes varied compared to the wild type. Thus, LPS is a secondary cell surface receptor for phage …

Evaluación de veinte híbridos de maíz (Zea mays L.) en cinco localidades de Nicaragua
… (modelo AMMI). Los híbridos H10 y H13 mostraron los mayores rendimientos promedios a través de todas las localidades, superando al mejor testigo H19 (H-INTA 991) en 13 y 14 % respectivamente, no obstante, expresaron su mayor potencial en ambientes favorables. Los híbridos H11, H15 y …

Multi-material Adhesive Bonded Joints Under Static And Dynamic Loading
… attention given to joints involving 3D printed H13 tool steel bonded to aluminum. The insights gained from this work aim to inform the design of lightweight, impact-resistant bonded structures and contribute to the broader understanding of dynamic adhesive joint behavior.</p>

Comparative Analysis of Flagellotropic Agrobacterium Phages
… and 7-7-1 and host Agrobacterium sp. H13-3. Chapter 1 is a literature review. Chapter 2 discusses the identification of the bacterial lipopolysaccharide as a secondary receptor for bacteriophage Milano, and the cross infectivity of the three bacteriophages with the three host bacteria. …

DISCOVERY AND FUNCTIONAL ANALYSES OF HESSIAN FLY EFFECTOR-ENCODING GENES
… candidate HF effector-encoding genes. Candidate vH13 failed to induce plant immune responses in H13-resistant wheat leaves when carried by Pseudomonas fluorescens. However, experiments with the plant pathogen Burkholderia glumae carrying candidates vH13 or vH16 suggest they might interfere with …

Rehardenable materials system with diffusion barrier for three-dimensional printing
… C stainless steel bar. A 0.8 [mu]m TiN-coated H13 tool-steel powder skeleton was successfully infiltrated with Cu-20Ni-20Mn infiltrant. Age hardening at 450° C for one day resulted in a high macrohardness of 40 HRC, surpassing the current 3DP metal system for injection molding tooling. Future …
