The paper considers the numerical solution process of the strength and stability problems of thin-walled shell structures taking into account the geometric nonlinearity, transverse shifts, and material orthotropy.

The Effect of Negative-Energy Shells on the Schwarzschild Black Hole [PDF]
We construct Penrose diagrams for Schwarzschild spacetimes joined by massless shells of matter, in the process correcting minor flaws in the similar diagrams drawn by Dray and 't Hooft, and confirming their result that such shells generate a horizon ...

Shell‐by‐Shell Functionalization of Inorganic Nanoparticles [PDF]
AbstractThe current state of the hierarchical chemical functionalization of inorganic nanoparticles (NPs) by shell‐by‐shell (SbS)‐assembly of organic layers around the NP cores is summarized. This supramolecular functionalization concept is based on two steps: 1) the covalent grafting of a first ligand–shell consisting of, for example, long chain ...

Formation and Incidence of Shell Galaxies in the Illustris Simulation [PDF]
Shells are low surface brightness tidal debris that appear as interleaved caustics with large opening angles, often situated on both sides of the galaxy center.

Partitioning of trace metals between soft tissues and shells of Patella aspera [PDF]
This paper describes the partitioning of iron, manganese, zinc, copper, cadmium, cobalt, nickel and lead between the soft tissues and the shells of the gastropod mollusc Patella aspera. Specimens of the limpet P aspera were collected from a clean coastal

Overwintering of spiders in empty snail shells is a little studied topic and in Slovakia similar research has not been carried out yet. Collecting shells was carried out in the eastern part of Slovakia, in winter at the turn of 2012/2013 and 2013/2014 ...

From Shell Logs to Shell Scripts [PDF]
Analysing the use of a Unix command shell is one of the classic applications in the domain of adaptive user interfaces and user modelling. Instead of trying to predict the next command from a history of commands, we automatically produce scripts that automate frequent tasks. For this we use an ILP association rule learner.

The accuracy of the Boundary Element Method (BEM) is strongly dependent on an accurate evaluation of boundary integrals. For thin-walled structures, collocation points and integration elements are often very close, making the kernel of the integrations ...

An Evolutionary Sequence of Expanding Hydrogen Shells in Galaxy Discs [PDF]
Large HI shells, with diameters of hundreds of pc and expansion velocities of 10-20kms-1 are well observed features of local gas rich galaxies. These shells could well be predicted as a result of the impact of OB associations on the ISM, but doubt has ...
