The uniformity of absorbed dose in a batch of sludge in a large-scale liquid sludge gamma irradiator has been examined by using sand samples separated from sludge as an <i style="">in-situ</i> dosimeter. Statistical analysis of the data, by applying ANOVA test, has been used to evaluate uniformity of dose. The re-circulation time for irradiation of sewage sludge to a dose of 3 kGy for its disinfection has been optimized using the data obtained. <br/> <br/>Page(s): 879-885 Sun, 28 Nov 2004 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/9658 Title: Systematization of L X-ray satellites I: L<img src='/image/spc_char/alpha.gif' border=0> satellites <br/> <br/>Authors: Misra, U D; Kumar, N <br/> <br/>Abstract: The iterative procedure, based on Hagström's method of the doubly modified Moseley plot, has been used for the first time for the systematization of L<img src='/image/spc_char/alpha.gif' border=0> X-ray satellites for 48 <u><</u> <i style="">Z</i> <u><</u> 80. This has resulted in: (i) the identification of a number of satellites measured by certain researchers and (ii) removal of anomalies in the measurements of the wavelength of some satellite lines. <br/> <br/>Page(s): 891-895 Sun, 28 Nov 2004 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/9657 Title: Indigenous development of a low cost high power 2 kW (CW), 2.45 GHz microwave system <br/> <br/>Authors: Jain, S K; Jain, Akhilesh; Hannurkar, P R <br/> <br/>Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> An indigenous low cost high power 2kW (CW), 2.45 GHz microwave system for Electron Cyclotron Resonance (ECR) proton source has been designed and developed using WR-284 waveguide sections. An ECR proton source (50 keV, 30 mA) is under development as an injector to Proton Synchrotron (PS) is being built at Centre for Advanced Technology (CAT), Indore. Using this microwave system the microwave power was delivered successfully to the plasma chamber and stabilized plasma was produced. The details of the design, fabrication and performance of the waveguide components are presented in this paper. </smarttagtype></smarttagtype> <br/> <br/>Page(s): 896-901 Sun, 28 Nov 2004 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/9656 Title: Ultrasonic studies on aqueous ternary electrolytes <br/> <br/>Authors: Pavai, R Ezhil; Vasantharani, P; Kannappan, A N <br/> <br/>Abstract: The density, viscosity and ultrasonic velocity have been measured in two ternary electrolytic mixtures of sodium chloride and manganese chloride in the aqueous mixture of magnesium sulphate and cadmium chloride at 308, 313 and 318 K. From these values the parameters like free volume, internal pressure, solvation number and viscosity <i style="">B</i>-coefficient have been calculated. The results are interpreted on the basis of ion-ion, ion-solvent and structure making/promoting tendency of the electrolytes. <br/> <br/>Page(s): 934-936 Sun, 28 Nov 2004 22:58:59 GMT
