An in vitro study in dual-flow continuous-culture fermentors was conducted with two different concentrations of monensin, cinnamaldehyde or garlic extract added to 1:1 forage-to-concentrate diet in order to determine their effects on selected rumen bacterial populations. Samples were subjected to total DNA extraction, restriction analysis of PCR amplified parts of 16S rRNA genes (ARDRA) and subsequent analysis of the restriction profiles by lab-on-chip technology with the Agilent's Bioanalyser 2100. Eub338-BacPre primer pair was used to select for the bacteria from the genera Bacteroides, Porphyromonas and Prevotella, especially the latter representing the dominant Gram-negative bacterial population in the rumen. Preliminary results of HaeIII restriction analysis show that the effects of monensin, cinnamaldehyde and garlic extract on the BacPre targeted ruminal bacteria are somewhat different in regard to targeted populations and to the nature of the effect. Garlic extract was found to trigger the most intensive changes in the structure of the BacPre targeted population. Comparison of the in silico restriction analysis of BacPre sequences deposited in different DNA databanks and of the results of performed amplified ribosomal DNA restriction analysis showed differences between the predicted and obtained HaeIII restriction profiles, and suggested the presence of novel, still unknown Prevotella populations in studied samples.

Članek obravnava izobraževanje o politiki v raznoterih pojavnih oblikah v kontekstu (neo)liberal- nega družbeno-političnega reda, ki mu je inherentna produkcija depolitizacije in negotovosti. Prikaže, kako so prevladujoče sistematizacije in prakse izobraževa- nja (tudi političnega), pa tudi politološke intervencije na področje (političnega) izobraževanja ujete v nepre- stano odpravljanje negotovosti in iskanje rešitev, pri čemer so servilne tržni racionalnosti in liberalni pred- stavniški demokraciji. Članek predvsem na podlagi Rancièrjevega in deloma Mouffinega motrenja politike in političnosti ponudi perspektivo, ki kritično naslavlja te formacije in procese, na tej osnovi pa konceptualizi- ra politično izobraževanje, ki ne izganja, temveč, obrat- no, vzame negotovost in družbeno enakost za svoje izhodišče. S tem ponudi alternativno formo političnega izobraževanja kot vedno-že negotovo prakso, ki izhaja iz (v rancièrjevskem smislu) radikalne enakosti in pred- stavlja disrupcijo obstoječemu konsenzualnemu (neo) liberalnemu redu. Ključni pojmi: negotovost, politično izobraževanje, politika, neoliberalizem, Rancière
