1. Winter harvest : organic vegetable production in unheated greenhouses in Central Europe

Author

Palme, W., Stopper, E., Palme, W., and Stopper, E.

Abstract

During winter time many greenhouses and polytunnels in Central Europe stay unused. Alternatively they are heated with fossil fuels which means high input of unsustainable energy. Imports from southern countries meet demand of fresh vegetables during that time. In this project a new cultivation system for harvesting leafy vegetables during winter without additional heating was developed by organic growers together with researchers and advisers in Austria.

Abstract

This paper reports that for the cases studied, and assuming a perfectly cut gear and pinion lead, the T-gear load distribution is slightly better than the Y-gear. However, pinion crowning would be more effective on the Y-gear than the T-gear., This paper reports that for the cases studied, and assuming a perfectly cut gear and pinion lead, the T-gear load distribution is slightly better than the Y-gear. However, pinion crowning would be more effective on the Y-gear than the T-gear.

Abstract

Exencephaly/anencephaly is a rare neural tube defect occurring early in embryogenesis. We report a 14-week-old fetus with exencephaly in whom central nervous system tissue was developed and preserved. There were 2 symmetrical structures grossly resembling cerebral hemispheres, which on histologic and ultrastructural study, consisted of a combination of ependymoblastomatous rosettes and canals and primitive neural tissue. The brainstem and spinal cord were partially normally formed, although descending tracts were not apparent. No cerebellar tissue was found. The eyes were formed. This appears to represent a rare example of exencephaly not covered by skin, which did not undergo necrosis and early transformation into a residual area cerebrovasculosa, characteristic of anencephaly. It may be appropriate to regard this as a unique neural tube closure defect that might be termed "ependymoblastomatous exencephaly."
