The thermodynamic quantities of dissociation contact and solvent-separated ion pairs into ions, conversion HBr ionogen in n-alcohols from methyl to n-octyl have been calculated by the procedure we set forth earlier for HCl – n-alcohol systems same solvents at 278.15–328.15 K. following regularities were established this work: a) positive values ΔdisGº increase with increasing temperature, numbe...

BACKGROUND Evidence shows that in Iran alcohol abuse rate may be of concern, especially among the youth. The mental and social health and addiction Department of the Ministry of Health and Medical Education has designed a plan to prevent, treat, and rehabilitate the patients abusing alcohol in a time period of 2011-2015. METHODS In a 6-month period, three guiding committees of experts in the ...

alcohol directly affects astroglial cell function, including inflammation-related activity.  and it also affects microglial cell development and function in specific ways that interfere with microglial interactions with the immune system and with neurons. neuroinflammatory processes might be involved in alcohol-induced brain damage. alcohol use, misuse and getting used to it causes different ki...

Human studies indicate that alcohol exposure during gestation not only increases the chance for later alcohol abuse, but also nicotine dependence. The flavor attributes of both alcohol and nicotine can be important determinants of their initial acceptance and they both share the component chemosensory qualities of an aversive odor, bitter taste and oral irritation. There is a growing body of ev...

Chitosan (CS) and alginate (Alg) are complementary in their membrane performance, but the combination of them is normally difcult to use due to their different solubilities. Layer-by-Layer deposition appears to be an effective method for improving the separation efciency of a composite membrane. In this work, the polyelectrolyte multilayer composite membranes (PEMCMs) wer...

Gums were precipitated from solutions gL,Tail End Syrup and Affination Syrup6sing.acidified alcohol. The precipitated solution was centrifuged and the gums washed by successive mixing, centrifuging and decanting with alcohol. The washed gums were dissolved in hot water and reprecipitated with acidified alcohol. After further washing the gums were re-dissolved. The gums and starch content of the...

based on some stationary periodic solutions and stationary soliton solutions, one studies the general solution for the relative lax system, and a number of exact solutions to the korteweg-de vries (kdv) equation are first constructed by the known darboux transformation, these solutions include double and triple singular periodic solutions as well as singular soliton solutions whose amplitude de...

Background and Aim: The hardness and wear resistance of denture teeth have great importance in the longevity of dentures. This study assessed the effect of 0.2% chlorhexidine (CHX) and alcohol-free Listerine on the microhardness of acrylic denture teeth. Materials and Methods: In this in-vitro experimental study, 26 Major Plus teeth were randomly divided into three groups for immersion in 0.2%...

This work reports on independent component analysis (ICA) as a tool used to discriminate between odour signals. Measurements of six different alcohol solutions were carried out with a commercial gas sensor array system, a so called electronic nose. The solutions were made of either pure propanol or butanol at concentration levels of 0.5%, 1% and 2%. Principal component analysis (PCA), a standar...
