Phase I of the International Study of Asthma and Allergies in Childhood has provided valuable information regarding international prevalence patterns and potential risk factors in the development of asthma, allergic rhinoconjunctivitis and eczema. However, in Phase I, only six African countries were involved (Algeria, Tunisia, Morocco, Kenya, South Africa(More)
A new series of multipotent antioxidants (MPAOs), namely Schiff base-1,2,4-triazoles attached to the oxygen-derived free radical scavenging moiety butylated hydroxytoluene (BHT) were designed and subsequently synthesized. The structure-activity relationship (SAR) of the designed antioxidants was established alongside the prediction of activity spectra for(More)
Benzyl α-l-rhamnopyranoside 4, obtained by both conventional and microwave assisted glycosidation techniques, was subjected to 2,3-O-isopropylidene protection to yield compound 5 which on benzoylation and subsequent deprotection of isopropylidene group gave the desired 4-O-benzoylrhamnopyranoside 7 in reasonable yield. Di-O-acetyl derivative of benzoate 7(More)
In the past, acoustical consultants could only try to convince the client/architect that with calculations and geometrical plots they could create an acoustically superb space. Now, by modeling the significant acoustical parameters of a design, we can preview a proposed acoustical solution and it is possible to identify the objective parameters that(More)
Rare earth copper sulfides, LnCuS2 (Ln 1⁄4 Ce, Pr, Nd, Sm, Gd and Tb), powders were synthesized by the following procedure: (1) Ln-Cu complex oxide was synthesized using the polymerized complex method, and (2) LnCuO2 was sulfurized by the CS2 gas. CS2 gas sulfurization combined with a polymerized complex method can reduce a reaction temperature and a(More)
With the rapid development of Internet, e-mail has become effective means of communication to share information. Through e-mail, we can send text messages, images, audio and video clips across the world within a fraction of time. In recent years, e-mail users are facing problem due to spam e-mails. Spam e-mails are unsolicited commercial/bulk e-mails sent(More)
In this research, we report the size-controlled synthesis and surface-functionalization of magnetite with the natural antioxidant gallic acid (GA) as a ligand, using in situ and post-synthesis methods. GA functionalization provided narrow size distribution, with an average particle size of 5 and 8 nm for in situ synthesis of gallic acid functionalized(More)
