Application of a Third Order Upwind Scheme to Viscous Flow over Clean and Iced Wings

A 3-D compressible Navier-Stokes solver has been developed and applied to 3-D viscous flow over clean and iced wings. This method uses a third order accurate finite volume scheme with flux difference splitting to model the inviscid fluxes, and second order accurate symmetric differences to model the viscous terms. The effects of turbulence are modeled using a Kappa-epsilon model. In the vicinity of the sold walls the kappa and epsilon values are modeled using Gorski's algebraic model. Sampling results are presented for surface pressure distributions, for untapered swept clean and iced wings made of NACA 0012 airfoil sections. The leading edge of these sections is modified using a simulated ice shape. Comparisons with experimental data are given

Inverse relationship between serum high density lipoprotein and negative syndrome in antipsychotic-naive schizophrenia

Background: Recent literature suggests a role for apolipoprotein L (apoL) aberrations in the pathogenesis of schizophrenia. ApoL is almost exclusively associated with apolipoprotein A-I in high-density lipoproteins (HDLs). The objective of this study was to examine the correlation between symptom scores and serum HDL in antipsychotic-naive schizophrenia patients. Methods: In this cross-sectional study, 60 antipsychotic-naive schizophrenia patients were systematically examined for their symptom scores, with good inter-rater reliability. Concurrently, an overnight fasting serum lipid profile from these patients was assessed. Results: Serum HDL had a significant inverse correlation with a total negative syndrome score (ρ=−0.43; p=0.001). Conclusions: The study observation supports the potential role for HDL abnormalities in the genesis of negative symptoms in schizophrenia. Clin Chem Lab Med 2010;48:95–8.Peer Reviewe

Auxiliary subunit regulation of high-voltage activated calcium channels expressed in mammalian cells

The effects of auxiliary calcium channel subunits on the expression and functional properties of high-voltage activated (HVA) calcium channels have been studied extensively in the Xenopus oocyte expression system, but are less completely characterized in a mammalian cellular environment. Here, we provide the first systematic analysis of the effects of calcium channel beta and alpha(2)-delta subunits on expression levels and biophysical properties of three different types (Ca(v)1.2, Ca(v)2.1 and Ca(v)2.3) of HVA calcium channels expressed in tsA-201 cells. Our data show that Ca(v)1.2 and Ca(v)2.3 channels yield significant barium current in the absence of any auxiliary subunits. Although calcium channel beta subunits were in principle capable of increasing whole cell conductance, this effect was dependent on the type of calcium channel alpha(1) subunit, and beta(3) subunits altogether failed to enhance current amplitude irrespective of channel subtype. Moreover, the alpha(2)-delta subunit alone is capable of increasing current amplitude of each channel type examined, and at least for members of the Ca(v)2 channel family, appears to act synergistically with beta subunits. In general agreement with previous studies, channel activation and inactivation gating was regulated both by beta and by alpha(2)-delta subunits. However, whereas pronounced regulation of inactivation characteristics was seen with the majority of the auxiliary subunits, effects on voltage dependence of activation were only small (< 5 mV). Overall, through a systematic approach, we have elucidated a previously underestimated role of the alpha(2)-delta(1) subunit with regard to current enhancement and kinetics. Moreover, the effects of each auxiliary subunit on whole cell conductance and channel gating appear to be specifically tailored to subsets of calcium channel subtypes

Schedule of Factors Influencing Adherence (SOFIA) to Psychiatric Treatment in Persons with Schizophrenia: Validity and Pilot Testing

Qualitative research has highlighted the complexinterplay of multiple factors that preclude persons withschizophrenia in rural Indian settings for discontinuedpsychiatric treatment. In this context, this paper aims toestablish the face and content validities of an interviewschedule titled „Schedule of Factors InfluencingAdherence (SOFIA) to Psychiatric Treatment in Personswith Schizophrenia‟ which comprehensively assessesfactors for discontinued  psychiatric treatment and   thefeasibility of its administration of the schedule. SOFIAcontains 16 factors. This schedule involves three phases of interviewing patients and family members.  This wasgiven to twelve experts who used likert scales to rate eachitems wells as the dimensions of the schedule. Later on,fifteen persons with schizophrenia were interviewed withSOFIA to test the feasibility of administration. The resultsshowed that Fourteen items were rated as eithersatisfactory (score=4) or very much satisfactory (score=5)by all twelve experts; remaining two were rated as 4 or 5by 11 experts. Regarding comprehensiveness of thefactors, scoring methods and general instructions given tothe interviewers, all provided scores &gt; 4; regardingmethod of interviewing, 11 provided score of &gt; 4; withregard to overall interview schedule, all experts providedscores &gt; 4. Pilot testing revealed that it took 60 minutes to administer SOFIA
