To gain a deeper insight into the potential interactions between individual aromatic hydrocarbons in a mixture, several benzo[a]pyrene (B[a]P) and 7H-dibenzo[c,g]carbazole (DBC) binary mixtures were studied. The biological activity of the binary mixtures was investigated in the HepG2 and WB-F344 liver cell lines and the Chinese hamster V79 cell line that stably expresses the human cytochrome P4...

The e−banking in Malaysia is growing rapidly with the fast development of Information and Communication Technology (ICT) infrastructure under Multimedia Super Corridor (MSC). Malaysian banks have stepped in e−banking to cater the needs of innovative customers. Having started with ATM facilities in 1981, they have introduced Internet banking as another new product recently regardless of the fact...

In this paper I explore Fauconnier and Turner's (1998) conceptual blending as an evaluative technique for user interface design. Conceptual blending theory offers a rich model that may account for meaning construction and meaning elaboration in design. Blending has been used previously to analyze jokes (Coulson, 1995), metaphor (Fauconnier & Turner, 1998), and Hebrew verb morphology (Mandelblit...

We present the design of a device for securing online transactions, e.g. for internet banking, which can protect against PC malware, including Man-in-the-Browser attacks. The device consists of a USBconnected smartcard reader with a small display and numeric keyboard, similar to devices currently used for internet banking. However, unlike existing devices, we rigorously stick to the design phil...

Smart cards are being integrated into a diverse range of industries: ranging from banking, telecom, transport, home/office access control to health and E-passport. Traditionally, cardholders are required to carry a smart card for each application. However, recent developments in the Near Field Communication (NFC) have renewed the interest in multiple applications for different services on a sin...

Due to the rise of technology, the possibility of fraud in different areas such as banking has been increased. Credit card fraud is a crucial problem in banking and its danger is over increasing. This paper proposes an advanced data mining method, considering both feature selection and decision cost for accuracy enhancement of credit card fraud detection. After selecting the best and most effec...

FVB/N mice wild-type, heterozygous or null for Cyp 1b1 were used in a two-stage skin tumor study comparing PAH, benzo[a]pyrene (BaP), dibenzo[def,p]chrysene (DBC), and coal tar extract (CTE, SRM 1597a). Following 20 weeks of promotion with TPA the Cyp 1b1 null mice, initiated with DBC, exhibited reductions in incidence, multiplicity, and progression. None of these effects were observed with BaP...

The automatic teller machine (ATM) is the most widely used e-Payment instrument in Nigeria. It is responsible for about 89% (in volume) of all e-Payment instruments since 2006 to 2008. Some customers have at least two ATM cards depending on the number of accounts operated by them and they represent the active users of the ATM cards. Furthermore, identity theft has been identified as one of the ...

CarD, an essential transcription regulator in Mycobacterium tuberculosis, directly interacts with the RNA polymerase (RNAP). We used a combination of in vivo and in vitro approaches to establish that CarD is a global regulator that stimulates the formation of RNAP-holoenzyme open promoter (RPo) complexes. We determined the X-ray crystal structure of Thermus thermophilus CarD, allowing us to gen...

In this study, DNA block copolymer (DBC) micelles with a polystyrene (PS) core and a single-stranded (ss) DNA shell were doped with ferrocene (Fc) molecules. Tapping mode atomic force microscopy (AFM) was used to study the morphology of the doped and undoped block copolymer aggregates. We show that introducing Fc molecules into the hydrophobic core does not affect the structural properties such...
