The Impact

Karaveera (Cerebra thevetia Linn.) is reported under Upavisha Dravya in classical ayurvedic pharmacopeias. It is observed that Shodhana (purification procedures) of the mool should be carried out before its internal administration. There are different Shodhana methods mentioned in Ayurveda. In this study Godugdha was used as media. The impact of Shodhana was evaluated by physico analytical study. It clearly proves physico analytical changes during Shodhana. Ashuddha Karaveera was taken on white clean cloth and they dumped in Pottali with Godugdha. Pottali was tied to middle of wooden rod dipped in Godugdha in stainless steel vessel and mild heat given to pottali in Dolayantra. Shuddha Karaveera was obtained and then washed with leuk warm water and dried. Ashuddha Karaveera contains toxin in it which was removed after Shodhana process. So that foreign matter, loss on drying was less in Shuddha Karaveera and due to Shodhan process with Godugdha total ash, acid insoluble ash was more than that of Ashuddha Karaveera.

Stainless Steel Vessel

Previous studies on solar cookers currently available in the market had indicated the need for redesigning to suit user requirements better. In order to help design engineers in developing next generation solar cookers, Gopal Naik and Girja Sharan use conjoint analysis to quantify values or utilities the users⁄ potential users associate with each important feature they desire Analysis reveals that three important features are: stainless steel vessel as against aluminium, provision of an electrical backup as against an exclusive solar device, and installation of an indicator to enable the user to judge the degree to which cooking has progressed.

Three Samples

Standard operating procedure for pharmaceutical preparation of Devdarvadyarishta has been developed in the present research work. A pilot scale study having 3 batches was carried out initially to find out the best possible fermenting vessel among glass jar, porcelain jar and stainless steel vessel and also to investigate for any possible hurdle related with fermentation process as honey and not jaggery is used as sweetening agent in this formulation. Three samples of Devdarvadyarishta as per conventional method were prepared in accordance with Bhaishjya Ratnavali and process for standard of Devdarvadyarishta was set in as a Quality specification for the same. Porcelain jar was found to be the best as per the results of pilot study as evident by alcohol content of 5.73%, 6.25% and 6.10% respectively in glass jar, porcelain jar and stainless steel vessel, the reaction being completed in between 38-47 days.  Approximate duration of Kwatha formation in all the batches was 9 hours with peak temperature during boiling being maintained at 920C. In all the three batches, fermentation started on 7th day, 7th day and 9th day, total duration of fermentation was 72 days, 70 days and 75 days, with % loss of 15.78%, 17.76% and 19.07% respectively. Mean % loss observed during preparation was 17.53%.

Ceramic membrane technology is used in water treatment due to the robustness of ceramic membranes, but ceramic membrane systems are costly as each membrane module is housed in individual casing. PWNT has developed a ceramic membrane system called the CeraMac which greatly reduced the capital cost of installing the system by housing up to 200 modules in a single stainless steel vessel. PWNT and PUB have jointly started a 18-month operation at Choa Chu Kang Waterworks (CCKWW). In this paper, the results of the optimization runs using settled water as feed has shown that membrane operation at flux of 200 lmh can be sustained with stable transmembrane pressure (TMP) and permeability, and the proposal to apply 0.5 mg/L residual ozone to the feed to investigate the effect of ozonated feed on membrane operational performance and fouling will be discussed.

Coupled Assay

A better synthetic route to β-carboxyaspartic acid (Asa) was achieved through condensation of sodium dibenzyl malonate and benzyl 2-bromoacetate as an alternative to two steps in the method of Koch etal. Catalytic hydrogenation at 5 atm pressure in a shaken stainless steel vessel removed protecting carbobenzyloxy groups. Asa was purified on a cation exchange column. An extract of E. coli was found to catalyse the decarboxylation of Asa in a doubly coupled assay designed to be specific for produced aspartic acid. Evidence for enzymatic decarboxylation includes complete loss of activity on boiling and progressive loss of activity on repeated freeze–thawing of the extract. Keywords: decarboxylation, β-carboxyaspartic acid, Asa decarboxylase.
