Phytoremediation of selenium-contaminated soils may be influenced by higher trophic levels including insects. We examined how selenium affects the behavior, survival, and development of the wasp parasitoid Cotesia marginiventris, parasitizing its natural host, the beet armyworm Spodoptera exigua, feeding on alfalfa, Medicago sativa, irrigated with water containing selenate. X-ray absorption spe...

The domesticated silkworm, Bombyx mori Linn., a lepidopteran molecular model and an important economic insect that are emerging as an ideal molecular genetic resource for solving a broad range of biological problems. The silkworm, B. mori produces massive amount of silk proteins during the final stage of larval development. These proteins are stored in the middle silk gland and they are dischar...

Earthworms are the most suitable biological indicators of radioactive pollution because they are the parts of nutritional webs, and are present in relatively high numbers. Four months old Eisenia fetida were exposed to different doses of gamma radiation, namely 1, 2, 3, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 & 60 Gy to study the effects of radiation on different reproductive parameters. The ...

The interaction of optically emitting clouds with warm X-ray gas and hot, tenuous radio plasma in radio jet cocoons is modelled by 2D compressible hydrodynamic simulations. The initial setup is the Kelvin-Helmholtz instability at a contact surface of density contrast 10. The denser medium contains clouds of higher density. Optically thin radiation is realised via a cooling source term. The cool...

In recent decades there has been an increasing use of remotely sensed data for precision agricultural purposes. Sericulture, the activity rearing silkworm (Bombyx mori L.) larvae to produce silk in form cocoons, is practice that rarely used remote sensing techniques but could benefit from them. The aim this work was investigate possibility using satellite imaging order monitor leaf harvesting m...

The development and characterization of three-dimensional topological magnetic textures has become an important topic in modern magnetism from both fundamental technological perspectives. Here, the authors stabilize skyrmionic cocoons by engineering properties Pt/Co/Al based multilayers with variable Co thickness. These new can be observed transmission x-ray holography. Their coexistence skyrmi...
