Using 1:1 <i style="">M</i> salicylic acid in sodium carbonate in the receiving phase, the amount of dye transported across the U-type bulk liquid membrane (BLM) after 70 min was found to be 97 ± 2 %. The percent recovery of dyes is not found to decrease in the presence of anions (Cl^- and SO₄^-) in the feed solution. <br/> <br/>Page(s): 529-533 http://nopr.niscair.res.in/handle/123456789/5161 Title: Charge transfer complexes of chloranil with drugs <br/> <br/>Authors: Veeraiah, T; Anjaiah, G; Reddy, P Kista <br/> <br/>Abstract: The study of charge transfer (CT) complexes of chloranil with drugs (Naproxen, Nerolin, Methyl anthranilate, Isoxsuprine and Nylidrin) showed that there is a significant interaction between the acceptor and donors as evidenced by colour changes and absorption spectra. From the position of CT bands, the ionization potentials (IPs) of donors were evaluated using appropriate equations. The donor’s abilities are in the following order: Naproxen > Nerolin > Methyl anthranilate > Isoxsuprine > Nylidrin. Benesi-Hildebrand plots, Job's variation method indicated the formation of 1:1 complex in each case. The stability constants that varied in the same order as IPs are useful in estimation of the concentration of drugs either in pure form or in formulations and give a guide to the estimation of the drugs in industry and pharmacy. Thermodynamic parameters (-ve values of <i style=""><img src='/image/spc_char/delta.gif'>H</i>) suggest that the formation of complex is exothermic. The <i style="">-</i><i style=""><img src='/image/spc_char/delta.gif'>S</i> values indicate a decrease in the degree of freedom of molecules upon complexation, while -<i style=""><img src='/image/spc_char/delta.gif'>G</i> values indicate that complex formation is spontaneous and the values give a relative estimation of interaction between donors and acceptor. <br/> <br/>Page(s): 504-508 http://nopr.niscair.res.in/handle/123456789/5159 Title: Performance evaluation and software validation of automatic bank of DC reference standard<b style=""></b> <br/> <br/>Authors: Sharma, Sudhir K; Ojha, V N <br/> <br/>Abstract: The paper discusses in detail the establishment, performance evaluation and software validation of automatic bank of DC reference standard, which is traceable to primary standard of voltage. The bank is used for calibration of reference standard/industrial instruments in dc voltage at par to the international level and for the dissemination of unit of volt in the country. The average values of Device Under Calibration (DUC), assigned using bank of DC reference standard in automatic and manual mode, are 10.000 0061 ± 0.000 0044 V and 10.000 0060 ± 0.000 0046 V respectively. The difference between their average values and expanded uncertainty are 0.1 x 10^-6 V and ± 0.2 x 10^-6 V respectively and are within the permissible limit of the stability of the reference voltage. <br/> <br/>Page(s): 487-490 http://nopr.niscair.res.in/handle/123456789/5157 Title: Fenugreek and other lesser known legume galactomannan-polysaccharides: Scope for developments <br/> <br/>Authors: Mathur, Vandana; Mathur, N K <br/> <br/>Abstract: Among useful plants, legumes stand next only to grasses, yet the variety of products produced from legumes are more numerous than those from grasses, which mainly contain glucans (starches & cellulose), hemicelluloses and sugars as carbohydrates. Some legume seeds additionally have galactomannans and amyloid as endosperm reserve polysaccharides, while many legume trees exude variety of gums. Because of unique industrial applications, legume galactomannans have acquired commercial value. There are many unutilized tropical legume galactomannans that could be exploited. This review presents galactomannans of some less common legumes. <br/> <br/>Page(s): 475-481
