Health care consumers no longer want to be passive receivers of treatment and care, they want to be involved. This shift is driven by the new information technology and a ‘social revolution’. Easy access to health information, thanks largely to the Internet, and active health consumer organizations have provided consumers with enabling independent health information. Individual consumers are also more willing to enter into a dialogue, participate and influence decisions concerning their own care. At the same time the consumer role becomes more diverse. Populations in many countries today are culturally, socially, and demographically diverse. Understanding consumer diversity is one of the greatest challenges facing health care providers. There is a risk that the quality of health care provided to consumers can vary depending on the skills of the professionals to tune into the values and preferences of the individual consumer. Health care providers need to listen to and incorporate consumers’ experiences into their health service offerings in new and creative ways. They need to engage in a dialogue with various consumer groups using multiple channels. There is a need for a new business logic, which would structurally help the providers, on an individual basis to deal with more sophisticated health care consumers. This is a review paper and provides a framework and a set of strategies for dealing with health consumer diversity. We draw on three interrelated theories – open systems theory, service management research and the concept of consumer segmentation to understand health care consumers’ attitudes and behaviour, and their expectations.

There exists a gap between control theory and control practice,i.e.,all control methods suggested by researchers are not implemented in real systems and,on the other hand,many important in dustrial problems are not studied in the academic *** problems can help close this gap and provide many opportunities for members in both the controls theory and application *** goal is to survey and give pointers to different general controls and modeling related benchmark problems that can serve as inspiration for future benchmarks and then specifically focus the benchmark coverage on automotive control engineering *** the paper reflections are given on how different categories of benchmark designers,benchmark solvers and third part users can benefit from providing,solving,and studying benchmark *** paper also collects information about several benchmark problems and gives pointers to papers than give more detailed information about different problems that have been presented.

It is possible and clinically relevant to distinguish between slow and rapid progressive spermatozoa in basic semen analysis. This is discussed in light of the different purposes of semen analysis for the subfertile couple and the male patient. The two groups of progressive spermatozoa should be distinguished to help ensure that pertinent information available in the semen sample is not neglected.

QCD-motivated models for hadrons predict an assortment of ＂exotic＂ hadrons that have structures that are more complex than the quark-antiquark mesons and three-quark baryons of the original quark-parton model. These include pentaquark baryons： the six-quark H-dibaryon~ and tetraquark, hybrid and glueball mesons. Despite extensive experimental searches, no unambiguous candidates for any of these exotic configurations have been identified. On the other hand, a number of meson states, one that seems to be a proton-antiproton bound state, and others that contain either charmed- anticharmed quark pairs or bottom-antibottom quark pairs, have been recently discovered that neither fit into the quark-antiquark meson picture nor match the expected properties of the QCD- inspired exotics. Here I briefly review results from a recent search for the H-dibaryon, and discuss some properties of the newly discovered states -the proton-antiproton state and the so-called XYZ mesons- and compare them with expectations for conventional quark-antiquark mesons and the predicted QCD-exotic states.

Sphingosine-1-phosphate (S1P) has diverse biological functions acting inside cells as a second messenger toregulate cell proliferation and survival, and extracellularly, as a ligand for a group of G protein-coupled receptors(GPCRs) named the endothelial differentiation gene (EDG) family. Five closely related GPCRs of EDG family(EDG1, EDG3, EDG5, EDG6, and EDG8) have recently been identified as high-affinity S1P receptors. Thesereceptors are coupled via Gi, Gq, G12/13, and Rho. The signaling pathways are linked to vascular cell migration,proliferation, apoptosis, intracellular Ca2+ mobilization, and expression of adhesion molecules. The formation of anatherosclerotic lesion occurs through activation of cellular events that include monocyte adhesion to the endothe-lium and vascular smooth muscle cell (VSMC) migration and proliferation. Thus, S1P signaling may play animportant role in the pathogenesis of atherosclerotic vascular disease. This review highlights S1P signalling invascular cells and its involvement in the formation of atherosclerotic lesions.

Film cooling is an important measure to enable an increase of the inlet temperature of a gas turbine and, thereby, to improve its overall efficiency. The coolant is ejected through spanwise rows of holes in the blades or endwalls to build up a film shielding the material. The holes often are inclined in the downstream direction and give rise to a kidney vortex. This is a counter-rotating vortex pair, with an upward flow direction between the two vortices, which tends to lift off the surface and to locally feed hot air towards the blade outside the pair. Reversing the rotational sense of the vortices reverses these two drawbacks into advantages. In the considered case, an anti-kidney vortex is generated using two subsequent rows of holes both inclined downstream and yawed spanwise with alternating angles. In a previous study, we performed large-eddy simulations (which focused on the fully turbulent boundary layer) of this anti-kidney vortex film-cooling and compared them to a corresponding physical experiment. The present work analyzes the simulated flow field in detail, beginning in the plenum (inside the blade or endwall) through the holes up to the mixture with the hot boundary layer. To identify the vortical structures found in the mean flow and in the instantaneous flow, we mostly use the λ 2 criterion and the line integral convolution (LIC) technique indicating sectional streamlines. The flow regions (coolant plenum, holes, and boundary layer) are studied subsequently and linked to each other. To track the anti-kidney vortex throughout the boundary layer, we propose two criteria which are based on vorticity and on LIC results. This enables us to associate the jet vortices with the cooling effectiveness at the wall, which is the key feature of film cooling.
