, 2010 We study mass transfer by Roche lobe overflow in close-in exoplanetary systems. The planet's atmospheric gas passes through the inner Lagrangian point and flows along a narrow stream, accelerating to 100-$200\kms$ velocity before forming an accretion ...

Properties of In-Plane Graphene/MoS2 Heterojunctions
, 2017 The graphene/MoS2 heterojunction formed by joining the two components laterally in a single plane promises to exhibit a low-resistance contact according to the Schottky-Mott rule. Here we provide an atomic-scale description of the structural, electronic,

Heterogeneous dynamic restoration of Ti–15Mo alloy during hot compression
Journal of Materials Research and TechnologyNear-β titanium alloys have shown low Young's modulus and good strength, making them excellent implant candidates. However, their processing using thermomechanical routes in single phase β region results in heterogeneous microstructures due to high ...

Joining of EN AW 6060 Pipes by Plastic Forming
Periodica Polytechnica Mechanical Engineering, 2023 The article deals with an innovative, but not widely used type of joining of aluminum pipes through experiments. The joints are formed by plastic forming. The process is carried out in one step using the principle of pipe expansion, in order to bring the mating surfaces of the two pipes into a suitable position for the subsequent joining, which is ...

Paenibacillus brasilensis sp nov., a novel nitrogen-fixing species isolated from the maize rhizosphere in Brazil [PDF]
, 2002 Sixteen nitrogen-fixing strains isolated from the rhizosphere of maize planted in Cerrado soil, Brazil, which showed morphological and biochemical characteristics similar to the gas-forming Paenibacillus spp., were phenotypically and genetically ...

Producing Hybrid Busbars by Fastening and Joining by Forming
, 2021 This paper is focused on hybrid busbars, which are crucial elements in modern electric vehicles for distributing electric power to multiple equipment such as the electric motor, the electric power steering unit, and the AC/DC converters. The authors investigate the possibility of replacing fastening by a new joining by forming process to assemble the ...

Joining by sheet-bulk forming of tubes to sheets
Procedia Manufacturing, 2018 Abstract This paper presents a new joining by forming process for connecting tubes to sheets that is carried out in two stages; (i) forming of an annular flange with rectangular cross section by partial sheet-bulk of the tube wall thickness and (ii) mechanical interlock by upsetting of the free tube end against a counterbored (flat-bottomed) sheet ...

Phylogenies of atpD and recA support the small subunit rRNA-based classification of rhizobia [PDF]
, 2001 The current classification of the rhizobia (root-nodule symbionts) assigns them to six genera. It is strongly influenced by the small subunit (16S, SSU) rRNA molecular phylogeny, but such single-gene phylogenies may not reflect the evolution of the ...
