Pyrolysis oil, a complex mixture of several organic compounds, produced during flash pyrolysis of organic lignocellulosic material was evaluated for its suitability as alternative carbon source for fungal growth and fermentation processes. Therefore several fungi from all phyla were screened for their tolerance toward pyrolysis oil. Additionally Aspergillus oryzae and Rhizopus delemar, both est...

background: substance abuse is one of the most complicated social problems. understanding socio-demographic characteristics of those who abuse substances could help deal with this problem more efficiently. the main objective of this study was to determine socio-demographic characteristics associated with alcohol drinking, cigarettes smoking and drug abuse among a sample of male medical universi...

OBJECTIVE Depression is highly prevalent among illicit drug users, and this co-occurrence is associated with poorer treatment outcomes. However, there has been limited empirical attention toward developing and assessing behavioral interventions for depression among illicit drug users. The objective of the current study was to test the efficacy of integrating a brief behavioral intervention for ...

Psychiatric emergencies are conditions that mostly destabilize the already frenetic activity of the Emergency Department. Sometimes the emergency is clearly referable to primitive psychiatric illness. Other times, psychiatric and organic symptoms can independently coexist (comorbidity), or develop together in different conditions of substance abuse, including alcohol and prescription drugs. Dif...

Various cultures (previously described), which oxidize thiosulfate in mineral media have been studied in an attempt to determine the products of oxidation. The transformation of sodium thiosulfate by Cultures B, T, and K yields sodium tetrathionate and sodium hydroxide; secondary chemical reactions result in the accumulation of some tri- and pentathionates, sulfate, and elemental sulfur. As a r...

Natural attenuation is presently used at numerous sites where groundwater is contaminated. In order to simulate this attenuation, reactive transport models are often used but they are quite complex and depend on both physical and chemical conditions in the aquifer. As complex numerical models cannot be used to study all possible cases, we develop here analytical solutions to draw general conclu...
