abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
an attempt to see when these properties attain their normal values during the course of treatment of kala-azar patients, it was found that even after a period of two months after the courses of injections are finished, the serum does not attain its normal value so far as these physical properties are concerned. Simultaneously with these experiments, Napier's aldehyde reaction has also been foll...
objective: polymerase chain reaction (pcr) is one of the most important progress in the field of molecular biology and diagnosis. despite simplicity in concept, the reaction needs complex interaction between target sequence, primers, dntps and dna polymerase for a successful amplification and diagnosis. for the detection of rna viruses highly sensetive and specific technique is required. hence ...
The fine chemical process has many environmental and safety problems related to the unavoidable use of various organic reactions which are highly involved with exothermic reactions, explosive intermediates, corrosive reagents, toxic or reactive gases, flammable pyrophoric compounds, extreme conditions. Limited by traditional batch process, efficiency these should be manually lowered keep reacti...
This study provides an assessment of local government progress in adaptation to marine climate change in Australia's coastal communities. Globally, coastal communities are vulnerable to a diversity of marine climate change impacts, and adaptation responses will need to be tailored to suit each unique socioecological situation. The responsibility of adaptation planning is largely placed on munic...
When integrating numerous in-car information and assistance systems, a consistent way of spatial distance presentation for drivers is required. A common practice is to use discrete textual information (e.g. 500 meters) in combination with a graphical bar representing relative spatial information. Hitherto there exists no design consistency with respect to bars for distance illustration. Contemp...
Recently, progress indicators have been proposed for SQL queries in RDBMSs. All previously proposed progress indicators consider each query in isolation, ignoring the impact simultaneously running queries have on each other’s performance. In this paper, we explore a multi-query progress indicator, which explicitly considers concurrently running queries and even queries predicted to arrive in th...
in the present investigation efforts have been made to synthesis polyvinyl pyridine (pvpy) /c60 conjugatesthrough 2, 2-azobisisobutyronitrile (aibn) initiated insitu polymerization of pvpy in scco2.the processof synthesis was monitored under different reaction conditions ranging 1200-1800psi, 60-90 oc over 6hours. the progress of polymerization was monitored rheoviscometrically. the concentrati...
abu ahmad askari - the scholar, philologist and hadith teller - was living in askar makram city that unfortunately this city and his literary works have lost. he wished to meet the scientist – saheb ibn abad. but why the works of abu ahmad and his hometown scientists were lost while they caused the progress of literature especially in elementary literary criticism and created a dam against the ...
