Improved soil and tomato quality by some biofertilizer products

The use of microbial inoculums is a part of sustainable agricultural practices. Among various bioeffectors, the phosphorus-mobilizing bacteria are frequently used. The objective of this study is to investigate the effect of some industrial biofertilizer inoculums, of containing P-mobilizing bacteria on the quantity and some quality parameters of tomato fruits. Spore-forming industrial Bacillus amyloliquefaciens FZB42 (Rhizovital) as single inoculums and combinations with other Bacillus strains (Biorex) were applied on Solanum lycopersicon Mill. var. Mobil test plant. Soil microbial counts, phosphorus availability, yield and fruit quality, such as total soluble solids (TSS) content and sugars (glucose, fructose) were assessed. The results found that single industrial inoculums of FZB42 product had positive effect on P-availability and fruit quality in the pots. Fruit quality parameters, TSS content, soluble sugars were significantly improved (p<0.05). Such better fruit taste was correlated significantly by the most probable number (MPN) microbial counts. Use of such bioeffector products is supported by the positive interrelation among measured soil characteristics and inside healthy quality parameters of tomato fruits

E pluribus unum? : A bevándorlástörténet és a migrációkutatás historiográfiája az Egyesült Államokban

The topic of immigration has occupied a central place in the historiography of American history since the end of the nineteenth century. The article looks at seminal works on the history of immigration to examine the major topics and paradigm shifts within immigration history and migration research in the last hundred years. During this period historians moved away from depicing immigration as a linear movement between two states towards more complex models of migration. America- and Europe-centered narratives have been complemented by research informed by transnational approaches. The last hundred years saw radical shifts in the definiton of migration, the institutional structures as well as the function of historical research. Narratives of immigration and migration have, however, consistently reflected the changing understandings of American society and identity

An Exiled Generation : German and Hungarian Refugees of Revolution, 1848-1871

Focusing on émigrés from Baden, Württemberg and Hungary in four host societies (Switzerland, the Ottoman Empire, England and the United States), Heléna Tóth considers exile in the aftermath of the revolutions of 1848 as a European phenomenon with global dimensions
