adsorption of 1-butanol, phenol, and p-nitrophenol on activated carbon havebeen studied. the results were used to testifying the validity of different modelsbased on thermodynamic principles: freundlich, langmuir and henry isotherms.the maximum capacity of adsorbent for three compounds was determined, theconstants of equilibrium were determined by freundlich isotherm and virialisotherm expressi...

Alice wants to query a database but she does not want the database to learn what she is querying. She can ask for the entire database. Can she get her query answered with less communication? One model of this problem is Private Information Retrieval, henceforth PIR. We survey results obtained about the PIR model including partial answers to the following questions. (1) What if there are k non-c...

retention behavior of molecules mostly depends on their chemical structure. retention data of biologically active molecules could be an indirect relationship between their structure and biological or pharmacological activity, since the molecular structure affects their behavior in all pharmacokinetic stages. in the present paper, retention parameters (rm0) of biologically active 1,2-o-isopropyl...

to compensate for some inferior properties of recycled papers, application of processing chemical aids such as chitosan can be quite effective in the wet end section of papermaking. in this study, the performance of chitosan biopolymer, individually or associated with nanobentonite was investigated as wet end additive on recycling process of white cuttings. for this purpose, the performance of ...

the present paper is concerned with the structural characteristics and contents of the russian resistance poets from the outset up to the end of the world war ii, 1941-1945. regarding the linguistic and literary structures of the resistance poetry of this period, such features as changes in the lexical structure of poems, outspokenness, proximity of poetry to slogans can be easily observed. sem...

the present study carried out an in vitro experiment on effects of salinity and temperature on acartia tonsa life cycle from caspian sea. during the experiment, temperature and salinity ranged 25, 27, 29 ± 1 °c and 12‰ and 17‰, respectively within a period of 60 days. spawning rate was measured using mesh size of 100 µ planktonic net from surface to 10 m depth. early results show that nauplii a...

abstract background and objective: parkinson's disease (pd) is an age-related neurodegenerative disorder with massive loss of dopaminergic neurons in the substantia nigra pars compacta. l-dihydroxyphenylalanine (l-dopa) substitution is still the gold standard therapy for pd. however, there has been little information available on neuroprotective and regenerative therapies for pd. due to the neu...
