BIOTOPICAL DISTRIBUTION AND SEASONAL ACTIVITY OF MODEL SPECIES OF THE FAMILY GNAPHOSIDAE (ARANEAE) IN ZEMEN GORGE (SW BULGARIA)

Biotopical distribution and seasonal activity of model species of the family Gnaphosidae (Araneae) in Zemen gorge (SW Bulgaria)

A faunistic study was carried out for three years in Zemen gorge (1984-1986).With SWIMSUIT the help of Barber-traps 675 gnaphosid spiders were caught in 4 localities, each with 2 habitats, meadow and forest.23 species were found in total and their biotopical distribution was recorded.The investigated habitats are faunistically similar, mainly in qu

Research on the operational performance of high speed permanent magnet generator with controlled rectifier in distributed generation

The uncontrolled rectifier and controlled rectifier which use fixed switching frequency control strategy are applied usually during the working of a high-power high- speed permanent magnet generator (HSPMG).Even for the controlled rectifier, it will generate harmonics.The electromagnetic performance of the HSPMG is also affected by these harmonics.

Comparing neutron and X-ray images from NIF implosions

Directly laser driven and X-radiation driven DT filled capsules differ in the relationship between neutron and X-ray images.Shot N110217, a directly driven DT-filled glass micro-balloon provided the first neutron images at the National Ignition Facility.As seen in implosions on the Omega laser, the neutron image can be enclosed inside Magazine Rack
