Identifikácia organických látok v slovenskom hnedom uhlí Vzorky slovenského hnedého uhlia z lokality Cígeľ a Handlová boli podrobené nadkritickej fluidnej extrakcii (SFE) oxidom uhličitým, modifikovaným 5 % metanolom. Extrakty, získané metódou SFE, boli podrobené plynovej chromatografii s hmotnostno-spektrometrickou identifikáciou (GC MS). Porovnaním s literárnymi údajmi hmotnostnej spektroskop...

The aim of this study was to describe the breeding sites of Culicoides species in Konya province, Turkey. The samples taken from 11 different habitats in Konya province were examined for Culicoides species. The collected adult Culicoides specimens were reared in plastic buckets in our laboratory. Among 2,798 specimens reared, 18 species were identified. Culicoides circumscriptus Kieffer, 1918 w...

Return on assets (ROA) from household enterprise is crucial for understanding the well-being and productivity of households in developing economies. Yet the definition and measurement of household enterprise ROA remain inconsistent or unclear. We illustrate potential measurement problems with examples from various actual surveys. We then take advantage of a detailed integrated household survey ...

From its beginnings, organic chemistry has been a partner to biology, often crossing the artificial boundary between the sciences to the benefit of both disciplines. This is even reflected in the use of the adjective “organic” to refer to the chemistry of carbon. As the field has matured, it has continued to address matters of structure and synthesis to increasingly encompass the grand challeng...

In recent year large amount of water and wastewater generated from various industries and produce organic matters and contaminated the water, this organic this organic compound in water poses serious problems to public health as well as environment. The advanced oxidation process (AOPs) is one of the advanced treatment method for wastewater remediation. In AOPs, ElectroFenton process (EFP) is o...

after considering the security for costs as a rarely considered establishment and analyzing legal points and problems concerning that security which is located among the articles on provisional remedy, and after having a look at the security for costs against foreign claimants, present research analysis brings the security for costs in probate matters as its main subject into focus to the exten...

Acidic rivers in Nova Scotia have low concentrations of Ca (calcium) and high concentrations of dissolved organic matter and total dissolved aluminum. Dissolved organic matter binds to aluminum to form organic aluminum complexes which are not toxic to Atlantic salmon. Increased H ion concentrations (acidity) coupled with the low concentrations of Ca have caused the mortality of salmon in Nova S...
