Lesser-known bug a bigger hospital threat: study

CTV Health — Sat, 20 Mar 2010 17:04:45 +0100

A dangerous, drug-resistant staph infection called MRSA is often seen as the biggest germ threat to patients in hospitals and other health care facilities. But infections from Clostridium difficile -- known as C-diff -- are surpassing MRSA infections, a study of 28 hospitals in the Southeast U.S. found. (Source: CTV Health)

Anti-Escherichia coli O157:H7 activity of free fatty acids under varying pH

Canadian Journal of Microbiology — Sat, 20 Mar 2010 16:19:30 +0100

Jinli Yang, Xianzhi Hou, Priya S. Mir, and Tim A. McAllister - Following screening of 4 strains of Escherichia coli O157:H7 (E32511, E318N, H4420N, and R508N) for acid tolerance, strain H4420N was selected for further study into... (Source: Canadian Journal of Microbiology)

Electronically excited and ionized states of the CHCHOH radical: A theoretical study

Journal of Chemical Physics — Sat, 20 Mar 2010 16:16:09 +0100

B. Karpichev, L. Koziol, K. Diri, H. Reisler, and A. I. Krylov The low lying excited electronic states of the 2-hydroxyethyl radical, CHCHOH, have been investigated theoretically in the range 57 eV by using coupled-cluster and equation-of-motion coupled-cluster methods. Both dissociation and isomerization pathways are identified. On the ground electronic potent ... [J. Chem. Phys. 132, 114308 (2010)] published Fri Mar 19, 2010. (Source: Journal of Chemical Physics)

Liquid-vapor equilibria and interfacial properties of n-alkanes and perfluoroalkanes by molecular simulation

Journal of Chemical Physics — Sat, 20 Mar 2010 16:16:09 +0100

Miguel A. Amat and Gregory C. Rutledge A molecular dynamics study is presented to assess the performance of a united-atom model in the prediction of liquid-vapor interfacial properties for short-chain perfluoroalkanes and their alkane counterparts. In particular, the ability of this model to discriminate between the surface-energy values ... [J. Chem. Phys. 132, 114704 (2010)] published Fri Mar 19, 2010. (Source: Journal of Chemical Physics)

Minimizing the scattering of a nonmagnetic cloak

Applied Physics Letters — Sat, 20 Mar 2010 16:15:49 +0100

Jingjing Zhang, Yu Luo, and Niels Asger Mortensen Nonmagnetic cloak offers a feasible way to achieve invisibility at optical frequencies using materials with only electric responses. In this letter, we suggest an approximation of the ideal nonmagnetic cloak and quantitatively study its electromagnetic characteristics using a full-wave scattering th ... [Appl. Phys. Lett. 96, 113511 (2010)] published Fri Mar 19, 2010. (Source: Applied Physics Letters)

Application of thermal lens response to monitor health status of red blood cells: A quantitative study of the cell death process by extracting thermal diffusivity and size

Applied Physics Letters — Sat, 20 Mar 2010 16:15:49 +0100

Srivathsan Vasudevan, George Chung Kit Chen, and Marta Andika We explore monitoring the death process of individual red blood cells (RBC) quantitatively by using thermal lens (TL) response. TL response is a noninvasive excitation/probe technique that reflects photothermal parameters (e.g., absorption, thermal diffusivity, size, etc.). Since these parameters of ... [Appl. Phys.

Sleep deprivation influences drug use in teens' social networks, study finds

ScienceDaily Headlines — Sat, 20 Mar 2010 15:54:19 +0100

Recent studies have shown that behaviors such as happiness, obesity, smoking and altruism are "contagious" within adult social networks. In other words, your behavior not only influences your friends, but also their friends and so on. Researchers have taken this a step farther and found that the spread of one behavior in social networks influences the spread of another behavior -- adolescent drug use.
