In the fields of medicine, biotechnology and pharmacology, drug discovery is process by which new candidate medications are discovered. Historically, drugs were discovered identifying active ingredient from traditional remedies or serendipitous discovery, as with penicillin. More recently, chemical libraries synthetic small molecules, natural products extracts screened in intact cells whole org...

IN THE MANAGEMENT of thyroid carcinoma, doxorubicin alone, or in combination with cisplatin , is considered the most active regimen, although it gives unsatisfactory response rates with significant side-effects [1-3]. Epirubicin is endowed with a spectrum of activity similar to doxorubicin and an equivalent response rate with less cardiotoxicity and acute myelosuppres­ sion [4, 5]. Carboplatin ...

Abstract: nanocrystalline nickel samples with the grain size of ~25 nm were prepared via direct current electrodeposition andaluminized for different durations by pack cementation method at 500 means of SEM, EDS and XRD techniques. According to results, short time aluminizing resulted in the formation of asingle aluminide layer whereas at long duration two distinct aluminide layers were formed....

We present the results of the first long-term user study of site-based login mechanisms which force and train users to login safely. We found that interactive site-identifying images received 70% detection rates, which is significantly better than passive indicators’ results [16, 9, 13]. We also found that login bookmarks, when used together with ‘non-working’ links, doubled the prevention rate...

Password-free login is a system that sets the user free from remembering the passwords used, so that the user can get an easy access to any website of his choice in a common password. The system is basically a password storage website that keeps all the login id's and password in a single database.
