Characterisation of Interaction between Combustion Dynamics and Equivalence Ratio Oscillations in a Pressurised Combustor
Authors: van Kampen Jaap F. , Kok Jim B.W. 
Published: October 2010

In regular operation, all gas turbine combustors have a significant spontaneous noise level induced by the turbulent high power flame. This noise is characteristic for the operation as it is the result of the interaction between turbulence and combustion. Pressure fluctuations may also be generated by thermoacoustic instabilities induced by amplification by the flame of the acoustic field in the combustor. This paper focuses on the characterisation of the latter process, the combustion dynamics, in a pressurized premixed natural gas combustor. In order to predict the thermo-acoustically unstable operating ranges of modern gas-turbines with the use of an acoustic network model, it is essential to determine accurately the flame transfer function. This transfer function gives the relationship between a perturbation upstream of the flame and its combustion response, leading to acoustic forcing. In this paper, the flame transfer function is obtained by experimental means in a combustor test rig. This test rig was built in the framework of the European DESIRE project, and has the ability to perform thermo-acoustic measurements up to an absolute pressure of 5 bars. The maximum power of the setup is 500 kW. The paper presents a method to determine the flame transfer function by factorizing it in six subfunctions. Systematically these subfunctions are determined. With the method presented, acoustic measurements on the steady, unperturbed flame and on the unsteady, actively perturbed flame are performed. The effect of pressure is investigated. The steady measurements are used to provide an acousto-combustion finger print of the combustor. In the unsteady measurements, the flame transfer function is reconstructed from the measured acoustic pressures. These flame transfer functions are compared to transfer functions obtained from a numerical experiment in CFD. Good agreement is obtained.

Published: October 2010

Objectives. We examined gender differences in sociodemographic, military service, and mental health characteristics among Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans. We evaluated associations between these sociodemographic and service characteristics and depression and posttraumatic stress disorder (PTSD) diagnoses. Methods. In a retrospective, cross-sectional study, we used univariate descriptive statistics and log binominal regression analyses of Department of Veterans Affairs (VA) administrative data on 329 049 OEF and OIF veterans seeking VA health care from April 1, 2002, through March 31, 2008. Results. Female veterans were younger and more likely to be Black and to receive depression diagnoses than were male veterans, who were more frequently diagnosed with PTSD and alcohol use disorders. Older age was associated with a higher prevalence of PTSD and depression diagnoses among women but not among men. Conclusions. Consideration of gender differences among OEF and OIF veterans seeking health care at the VA will facilitate more targeted prevention and treatment services for these newly returning veterans.
Mental Health Disorders, Psychological Distress, and Suicidality in a Diverse Sample of Lesbian, Gay, Bisexual, and Transgender Youths
Authors: Mustanski Brian S. , Garofalo Robert , Emerson Erin M. 
Published: October 2010

Objectives. We examined associations of race/ethnicity, gender, and sexual orientation with mental disorders among lesbian, gay, bisexual, and transgender (LGBT) youths. Methods. We assessed mental disorders by administering a structured diagnostic interview to a community sample of 246 LGBT youths aged 16 to 20 years. Participants also completed the Brief Symptom Inventory 18 (BSI 18). Results. One third of participants met criteria for any mental disorder, 17% for conduct disorder, 15% for major depression, and 9% for posttraumatic stress disorder. Anorexia and bulimia were rare. Lifetime suicide attempts were frequent (31%) but less so in the prior 12 months (7%). Few racial/ethnic and gender differences were statistically significant. Bisexually identified youths had lower prevalences of every diagnosis. The BSI 18 had high negative predictive power (90%) and low positive predictive power (25%) for major depression. Conclusions. LGBT youths had higher prevalences of mental disorder diagnoses than youths in national samples, but were similar to representative samples of urban, racial/ethnic minority youths. Suicide behaviors were similar to those among representative youth samples in the same geographic area. Questionnaires measuring psychological distress may overestimate depression prevalence among this population.
Comparative Analysis of National Legislation in Support of the Revised International Health Regulations: Potential Models for Implementation in the United States
Authors: Katz Rebecca , Kornblet Sarah 
Published: October 2010

In 2005, the World Health Organization adopted the revised International Health Regulations, or IHR (2005), to establish obligations for detecting and responding to public health emergencies of international concern. The success of the IHR (2005) rests on the ability of states to implement the objectives and to execute the regulations in a legal and politically acceptable manner. Implementation of the IHR (2005) may be challenging for federalist nations, where most public health regulatory power lies in local rather than in national governments. We examine the implementation strategies of 4 nations: Australia, Canada, Germany, and India. The methods currently being considered by these nations for executing the IHR (2005) are potentially applicable models for the United States to consider.
Transforming the Nation's Health: Next Steps in Mental Health Promotion
Authors: Power A. Kathryn 
Published: October 2010

The National Research Council and the Institute of Medicine have called for making the healthy mental, emotional, and behavioral development of young people a national priority. The Substance Abuse and Mental Health Services Administration (SAMHSA) in the US Department of Health and Human Services is uniquely positioned to help develop national mental health policies that promote mental health and prevent mental illnesses. In this article I describe the role of mental health in overall health, I make the case for a public health approach to mental health promotion and mental illness prevention, and I outline a strategy to promote individual, family, and community resilience. I also describe how SAMHSA works to achieve these goals. Ultimately, true health reform will not succeed without a comprehensive, committed focus on the mental health needs of all Americans.
Change in Level of Positive Mental Health as a Predictor of Future Risk of Mental Illness
Authors: Keyes Corey L. M. , Dhingra Satvinder S. , Simoes Eduardo J. 
Published: October 2010

Objectives. We sought to describe the prevalence of mental health and illness, the stability of both diagnoses over time, and whether changes in mental health level predicted mental illness in a cohort group.Methods. In 2009, we analyzed data from the 1995 and 2005 Midlife in the United States cross-sectional surveys (n = 1723), which measured positive mental health and 12-month mental disorders of major depressive episode, panic, and generalized anxiety disorders.Results. Population prevalence of any of 3 mental disorders and levels of mental health appeared stable but were dynamic at the individual level. Fifty-two percent of the 17.5% of respondents with any mental illness in 2005 were new cases; one half of those languishing in 1995 improved in 2005, and one half of those flourishing in 1995 declined in 2005. Change in mental health was strongly predictive of prevalence and incidence (operationalized as a new, not necessarily a first, episode) of mental illness in 2005.Conclusions. Gains in mental health predicted declines in mental illness, supporting the call for public mental health promotion; losses of mental health predicted increases in mental illness, supporting the call for public mental health protection.
The Structure of the Genetic and Environmental Influences on Mental Well-Being
Authors: Keyes Corey L. M. , Myers John M. , Kendler Kenneth S. 
Published: October 2010

Objectives. We sought to investigate the structure of the genetic and environmental influences on 3 measures of mental well-being. Methods. Analyses focused on the subsample of 349 monozygotic and 321 dizygotic same-sex twin pairs from a nationally representative sample of twins who completed self-report measures of emotional, psychological, and social well-being. Results. The best-fit model contained a common pathway to all 3 measures of well-being, no shared environmental effects, and 1 set of parameters for men and women. Heritability for the latent “mental well-being” factor was high (72%) and best indexed by psychological well-being. Moderate trait-specific genetic effects were seen for emotional and social well-being. Nonshared environmental effects for all measures were mostly trait specific. Conclusions. Genetic influences on the measures of mental well-being reflect a single, highly heritable genetic factor, although some trait-specific genetic influences were seen for emotional and social well-being. Moderate proportions of environmental influences were also shared, but the majority of unique environment was trait-specific.

Summary

Background and objectives
This study aimed to investigate the influence of social support and other psychosocial factors on mortality, adherence to medical care recommendations, and physical quality of life among hemodialysis patients.

Design, setting, participants, & measurements
Data on 32,332 hemodialysis patients enrolled in the Dialysis Outcomes and Practice Patterns Study (1996 to 2008) in 12 countries were analyzed. Social support and other psychosocial factors related to ESRD and its treatment were measured by patient self-reports of health interference with social activities, isolation, feeling like a burden, and support from family and dialysis staff. Cox regression and logistic regression were used to examine associations of baseline social support and other psychosocial factors with all-cause mortality and with other measured outcomes at baseline, adjusting for potential confounders.

Results
Mortality was higher among patients reporting that their health interfered with social activities, were isolated, felt like a burden, and were dissatisfied with family support. Poorer family support and several psychosocial measures also were associated with lower adherence to the prescribed hemodialysis length and the recommended weight gain between sessions. Some international differences were observed. Poorer self-reported social support and other psychosocial factors were associated with poor physical quality of life.

Conclusions
Poorer social support and other psychosocial factors are associated with higher mortality risk, lower adherence to medical care, and poorer physical quality of life in hemodialysis patients. More research is needed to assess whether interventions to improve social support and other psychosocial factors will lengthen survival and enhance quality of life.

Anhemialges bakeri sp. nov. (Analgoidea, Analgidae) — a new species of feather mite from the Common Chiffchaff Phylloscopus collybita (Passeriformes, Sylviidae) from England
Authors: Dabert Jacek , Nattress Barry , Labrzycka Anna 
Published: October 2010

AbstractA new species of the poorly known feather mite genus Anhemialges Gaud, 1958 is described from the Common Chiffchaff Phylloscopus collybita. Anhemialges bakeri sp. nov. differs from all other species of the genus by the shape of setae w and s on tarsi III, which are hair-like and slightly thickened in basal and median parts. In all other described species of Anhemialges, setae w and s on tarsi III are blade-like or shaped as thick spines. The lack of leg III hypertrophy is discussed and interpreted as characteristic feature of the species rather than male homeomorphy. Remarks about the recent and possible species richness of the genus Anhemialges are given.

AbstractDiploproctodaeum monstrosum sp. nov. is described from Arothron stellatus and A. mappa from off Lizard Island, northern Great Barrier Reef. It differs from its congeners in having a body-length ventral scoop. Diploproctodaeum triodoni sp. nov. is described from Triodon macropterus off New Caledonia. It is distinguished by the extensive vitelline fields usually reaching to the ventral sucker and the folded scoop margins. Other related species are reported from new hosts or localities and dimensions are supplied for: Diploproctodaeum haustrum from Aluterus monoceros off New Caledonia; Diploproctodaeum arothroni from Arothron hispidus off Lizard Island and Ningaloo Reef, northern Western Australia, A. nigropunctatus off Lizard Island and Arothron manilensis off New Caledonia; Diploproctodaeum macracetabulum from Abalistes stellatus on the Swain Reefs, southern Great Barrier Reef and off New Caledonia; Diploproctodaeum momoaafata from Ostracion cubicus off Lizard Island; Diploproctodaeum rutellum from Platax teira off Heron Island, southern Great Barrier Reef; Diploproctodaeoides longipygum from Abalistes stellatus on the Swain Reefs and off New Caledonia; Diplocreadium tsontso from Balistoides conspicillum off Heron Island; Bianium arabicum from Lagocephalus sceleratus off New Caledonia. Attention is drawn to apparent convergent evolution in the body form of several families of trematodes infecting tetraodontids and especially species of Arothron.

AbstractCaligus uranoscopi Vaissière, 1955 (Copepoda, Caligidae) is redescribed based on specimens collected from the gill arches of red mullet, Mullus barbatus barbatus L., 1758, caught off the Algerian coast. Caligus uranoscopi is reported for the first time from the east coast of Algeria and M. barbatus barbatus is a newly recorded host for this parasite. The parasite is uncommon and may be restricted to Algerian coasts. Some remarks are given on the species of Caligidae known from Algeria.
Low prevalence of haemosporidian parasites in the introduced house sparrow (Passer domesticus) in Brazil
Authors: Lima Marcos , Simpson Lucy , Fecchio Alan , Kyaw Cynthia 
Published: October 2010

AbstractSpecies that are introduced to novel environments can lose their native pathogens and parasites during the process of introduction. The escape from the negative effects associated with these natural enemies is commonly employed as an explanation for the success and expansion of invasive species, which is termed the enemy release hypothesis (ERH). In this study, nested PCR techniques and microscopy were used to determine the prevalence and intensity (respectively) of Plasmodium spp. and Haemoproteus spp. in introduced house sparrows and native urban birds of central Brazil. Generalized linear mixed models were fitted by Laplace approximation considering a binomial error distribution and logit link function. Location and species were considered as random effects and species categorization (native or non-indigenous) as fixed effects. We found that native birds from Brazil presented significantly higher parasite prevalence in accordance with the ERH. We also compared our data with the literature, and found that house sparrows native to Europe exhibited significantly higher parasite prevalence than introduced house sparrows from Brazil, which also supports the ERH. Therefore, it is possible that house sparrows from Brazil might have experienced a parasitic release during the process of introduction, which might also be related to a demographic release (e.g. release from the negative effects of parasites on host population dynamics).
Characterisation of NcGRA7 and NcSAG4 proteins: Immunolocalisation and their role in the host cell invasion by Neospora caninum tachyzoites

Published: October 2010

AbstractNeospora caninum negatively impacts bovine reproductive performance around the world. Addressing this problem requires a greater understanding of the parasite’s molecular biology. In this study, monoclonal antibodies against recombinant proteins were successfully developed and employed to characterise two different proteins of N. caninum: the acute phase-associated NcGRA7 and the chronic phase-associated NcSAG4. Immunofluorescence with the anti-rNcGRA7 monoclonal antibody suggested that NcGRA7 trafficks from tachyzoite dense granules to the matrix of the parasitophorous vacuole and parasite’s surroundings. Furthermore, NcGRA7 is also expressed in the bradyzoite stage and localised on the matrix of bradyzoite-positive vacuoles. NcGRA7 appears to be partially involved in the tachyzoite-invasion mechanisms, as an anti-rNcGRA7 monoclonal antibody partially inhibited in vitro tachyzoite-invasion. A monoclonal antibody specific for NcSAG4 confirmed this protein’s bradyzoitespecific expression both by western blot and immunofluorescence. However, some bradyzoite-positive vacuoles only weakly expressed NcSAG4, if it was expressed at all. The specificity of the anti-rNcSAG4 monoclonal antibody was confirmed by the recognition of the NcSAG4 in the membrane surface of Nc-1SAG4c transgenic tachyzoites, which constitutively expresses NcSAG4. Blocking NcSAG4 of Nc-1SAG4c tachyzoites with the monoclonal antibody did not affect host cell invasion. However, its implication on the host cell adhesion or host immune evasion should not be discarded.
New philometrids (Nematoda, Philometridae) from head tissues of two serranid fishes (Epinephelus morio and Mycteroperca microlepis) off Florida, northern Gulf of Mexico
Authors: Moravec František , Bakenhaster Micah , Fajer-Avila Emma 
Published: October 2010

AbstractA new species of nematode, Philometra morii sp. nov. (Philometridae), is described from males and gravid females collected from the mouth cavity of the red grouper, Epinephelus morio (Valenciennes) (Serranidae, Perciformes), from the northen Gulf of Mexico, off Florida, USA. The new species is characterized mainly by the length of spicules (84–90 and 72–87 μm) and the length (54 μm) and structure of the gubernaculum in the male, and by the presence of three large oesophageal teeth protruding from the mouth, the number and arrangement of small cephalic papillae (8 papillae in 4 pairs of external circle and 6 single papillae of internal circle), the length (1.09–1.50 mm) and structure of the oesophagus and two large papilla-like caudal projections, and by the length of their bodies (19.34–30.07 mm). Philometra morii is the third species of this genus reported from E. morio in the Gulf of Mexico, differing from the two previously described species, in addition to morphological features, by the site of infection in this host (mouth cavity and sinuses vs oculo-orbits or gonads). From the same region (northern Gulf of Mexico, off Florida), gravid females of Philometra Costa, 1845, morphologically and biometrically similar to those of P. morii, were found in the subcutaneous tissues and sinuses of the head of another serranid fish (gag), Mycteroperca microlepis (Good et Bean). Although their conspecificity with P. morii cannot be excluded, they have been designated as Philometra sp. until conspecific males are discovered and described. Based on light and scanning electron microscopy examination (latter used only for females), both these forms are described.
