Abstract We demonstrate that planet formation via pebble accretion is sensitive to external photoevaporation of the outer disc. In accretion, planets grow by accreting from a flux solids (pebbles) radially drift inwards production front. If truncates disc fast enough, it can shorten time before front reaches edge, cutting off supply for hence limiting mass reservoir growth. Conversely, cloud sh...

The behavior of externally prestressed composite beams under short term loading has been studied. A computer program developed originally by Oukaili to evaluate curvature is modified the deflection beam flexural load. analysis model based on deformation compatibility entire structure that allows determine full history strain and stress distribution along cross section depth, increment in extern...

Star clusters are known to be formed in turbulent molecular clouds. How turbulence is driven clouds and what effect this has on star formation still unclear. We compare a simulation setup with driving everywhere periodic box where only around the outside of box. analyse resulting gas distribution, kinematics, population stars that from cloud. Both setups successfully produce velocity field powe...

An electro-optic tunable single and multi-channel optical filter based on one-dimensional defective photonic crystal (1DDPC) structure is proposed. A couple of externally tunable defects in arrangement of (AB)5D1(BA)D2(BA)5, where A and B are dielectric materials, D1 and D2 are the tunable defects are used. The defects are composed of the ferroelectric LiNbO3 crystals and two pairs of thin Ag l...
