Nonconvolution nonlinear integral Volterra equations with monotone operators
Some results about existence, uniqueness, and attractive behaviour of
solutions for nonlinear Volterra integral equations with non-convolution
kernels are presented in this paper. These results are based on similar ones
about nonlinear Volterra integral equations with convolution kernels and some
comparison techniques. Therefore, this paper is devoted to find a wide class of
nonconvolution Volterra integral equations where their solutions behave like
those of Volterra equations with convolution kernels.Comment: 13 page

Aharonov-Bohm Effect and Hidden Photons
Signs of hypothetical light gauge bosons from a hidden sector may appear in
Aharonov-Bohm-like experiments. The absence of signal in carried on experiments
allow us to set a modest constraint to the mass and coupling constant of these
particles. Our findings open the possibility to exploit the leaking of hidden
magnetic field in a different setup of experiments.Comment: Contributed to the 9th Patras Workshop on Axions, WIMPs and WISPs,

Improved retort for cleaning metal powders with hydrogen
Improved cleaning retort produces uniform temperature distribution in the heated zone and minimizes hydrogen channeling through the powder bed. Retort can be used for nonmetallic powders, sintering in a reducing atmosphere, and for cleaning powders in reduction atmospheres other than hydrogen
