Lignite Basins in Poland after 1945

Health policy regarding the fight against veneral diseases in Poland in the years 1945-1958

One of the most serious health problems occurring among population living in the post-war Poland comprised venereal diseases, including mainly syphilis, which reached proportions that had not been observed since the second half of the 20th century 1). As it was believed at that time, the spread of the said diseases became epidemic. It concerns particularly Regained Territories, where 20-30% of ...

Biodiversity of Macroinvertebrates in Oxbow-Lakes of Early Glacial River Basins in Northern Poland

River basins are very complex systems which include both abiotic and biotic elements. Such a high number of components results in a situation that normal functioning of river with adjacent areas depends on a set of hydrological and geological processes. They influence biological diversity observed in river basins (Arscott et al., 2005; Marshall et al., 2006). Proper assessment of a lotic system...

Complication after breast implantation in Poland syndrome.

Congenital or developmental deformities of the chest rarely cause severe functional problems in the manner of larger anomalies of the limbs. Poland syndrome is known as a variety of associated anomalies centered on the trunk and upper limbs. The authors report the case of a 28-year-old female with absence of the pectoralis major muscle and depression of the left anterior thoracic wall (sunken c...

Treatments of Çan Lignite with Some Mineral Acids after Sodyum Hydroxide Washing

The fossil properties can be increased via enrichment process. It is the process that removes sulfur and mineral matter without changing the organic structure. In this study, Çan lignite was demineralized with some mineral free acid of 5% such as HCOOH and some mineral acids of 5% such as HNO3, H2SO4, HCl, H3PO4 and HF after 5% NaOH washing. The best sulfur and mineral matter performed were obt...
