A high ozone episode in winter 2013 in the Uinta Basin oil and gas region characterized by aircraft measurements

Abstract. During the winter of 2012–2013 atmospheric surface ozone mole fractions exceeded the US 8 h standard of 75 ppb on 39 days in the Uinta Basin of Utah. As part of the Uinta Basin Winter Ozone Study (UBWOS) aircraft flights were conducted throughout the basin with continuous measurements of ozone (O3), methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), nitrogen dioxide (NO2), and discrete whole air flask samples for determination of ∼50 trace gases including a number of non-methane hydrocarbons (NMHCs). During the course of seven flights conducted between 31 January and 7 February 2013, coinciding with strong, multi-day temperature inversions, O3 levels gradually built up in the shallow boundary layer from ∼45 ppb to ∼140 ppb. Near-surface CH4 mole fractions increased during the episode from near background levels of ∼2 ppm to over 10 ppm. Based on elevated levels of CH4 across the basin and high correlations of CH4 with NMHCs from the discrete air samples, O3 precursor NMHCs were also inferred to be elevated throughout the basin. Discrete plumes of high NO2 were observed in the gas production region of the basin suggesting that gas processing plants and compressor facilities were important point sources of reactive nitrogen oxides (NOx). Vertical profiles obtained during the flights showed that the high O3 mole fractions (as well as other elevated constituents) were confined to a shallow layer from near the ground to 300–400 m above ground level (m a.g.l.) capped by a strong temperature inversion. The highest mole fractions of the measured constituents during the study period were in an isothermal cold layer that varied from ∼300 m depth on 4 February to ∼150 m on 5 February. A gradient layer with declining mole fractions with altitude extended above the isothermal layer to ∼1900 m a.s. l. (300–400 m a.g.l.) indicative of some mixing of air out of the boundary layer. O3 mole fractions continued to increase within the basin as the high O3 episode developed over the course of a week. CH4 mole fractions, on the other hand, leveled off after several days. On several flights, the aircraft sampled the plume of a coal-fired power plant (located east of the main gas field) flowing above the inversion layer. These measurements ruled out the effluents of the power plant as a significant source of NOx for O3 production beneath the temperature inversion in the basin. The presence of elevated O3 precursors within the basin and the rapid daytime production of O3 in the atmosphere beneath the temperature inversion both indicated that O3 was being produced from precursors emitted within the basin beneath the temperature inversion. Although observations show that horizontal winds in the surface layer were relatively light during the high ozone event, they were sufficient to disperse precursors up to 80 km from primary sources in the main gas field in the southeast quadrant to the balance of the Uinta Basin.
Staying and performing: How human resource management practices increase job embeddedness and performance

Purpose – The purpose of this paper is to empirically examine the effect of human resource management (HRM) practices on employees’ organisational job embeddedness and job performance. Following the ability-motivation-opportunity (AMO) model of HRM, the authors predicted that ability-, motivation- and opportunity-enhancing HRM practices would relate to fit, links and sacrifice components of job embeddedness, with these components mediating the relationship between HRM and employee job performance. Design/methodology/approach – Data were collected from a matched sample of 197 Chinese state-own firm employees and their supervisors. Multiple mediation test was used to test direct and mediating effects. Findings – Results indicated that HRM practices contribute to the creation and development of embeddedness, and the improvement of job performance. The job embeddedness components of fit, links and sacrifice were found to mediate the HRM-job performance relationship. The results suggest that organisations can .
How youth picture gender injustice: building skills for HIV prevention through a participatory, arts-based approach

Based on the existing literature on the positive relationship that exists between high instances of HIV infections and a high degree of gender injustices in southern Africa, there is clearly a need for HIV-prevention interventions, to focus on the need for changing the existing gender norms. Social change begins with change at the individual level, so the question that this article attempts to answer is : How can we engage youth as key actors in educating their peers on HIV prevention, through a gender lens? Proceeding from a critical paradigm, the article describes how a participatory action-research design, using arts-based methods, has enabled youth to develop self-efficacy beliefs in regard to their ability to design and implement peer- education interventions, in order to raise awareness in the school community of the impact of gender injustices on the lives of youth. The data were collected through drawings, focus-group interviews, photographs, and video recordings of peer interventions. Thematic analysis of the data provides convincing evidence that arts-based methods are effective in developing youth agencies to create and disseminate powerful peer interventions around gender injustice that may make a significant contribution to changing gender norms.

Antiviral Activity of Four Commercial Tilmicosin Preparations against Porcine Reproductive and Respiratory Syndrome Virus (PRRSV): An In Vitro Study

The efficacy of four commercial tilmicosin preparations (A, B, C and D) against type 2 porcine reproductive and respiratory syndrome virus (PRRSV), 01NP1 (Thai isolate), infection in cultured pulmonary alveolar macrophages (PAMs) was conducted in vitro. Primary PAMs were collected from four 4-week-old PRRSV-free pigs. After separately plated onto four 24-well plates, PAMs were treated separately by 4 commercial tilmicosin preparations of 2 concentrations each (0.1 mg/ml and 0.01 mg/ml). The treated PAMs were inoculated with 0.05 MOI of 01NP1 strain and were stained with PRRSV specific antibody using immunoperoxidase monolayer assay (IPMA) to evaluate the quantity of PRRSV infected cells after 12 hours post infection (HPI). Comparing to the untreated-tilmicosin PRRSV-infected PAMs, all tilmicosin-treated preparations exhibited significant virus titer reduction against 01NP1. Based on the results, 0.01 mg/ml of tilmicosin B solution exhibited the greatest PRRSV-titer reduction (65%), but was not statistically different from the others. The results indicated that tilmicosin could be one of the effective chemotherapy in reducing type 2 PRRSV infection in vitro regardless of differences in the preparations. The information obtained is of interest for practitioners for future study of implementation of tilmicosin use in PRRSV-positive farms.
The Relationship between School Related Variables and Motivational Patterns of Undergraduates: A Logistic Regression Analysis [La relación entre las variables relacionadas con la escuela y los patrones motivacionales de los estudiantes universitarios: un análisis de regresión logística]

Abstract: The purpose of this study is to investigate the relationships between gender, academic achievement, and satisfaction with degree program, and motivational patterns of undergraduates. The sample of the study consisted of 259 participants (141 females, 118 males) who were defined according to their motivational patterns as having either autonomous motivation (n=127) or controlled motivation (n= 132) among 732 participants who were selected randomly from the undergraduates attending Anadolu and Osmangazi Universities in Turkey. The data were collected via the Turkish Version of the Academic Motivation Scale. The findings obtained from 732 participants by using the linear regression analysis technique indicated that autonomous motivation predicted the academic achievement positively. The logistic regression analysis conducted on 259 participants also revealed that satisfaction with the degree program and being male increased the autonomous motivation significantly. The findings were discussed in the light of related literature. Keywords: Motivational patterns; educational outcomes; logistic regression.

Foraging range, habitat use and minimum flight distances of East Atlantic Light-bellied Brent Geese Branta bernicla hrota in their spring staging areas

Global Positioning System (GPS) satellite telemetry was used to determine the foraging range, habitat use and minimum flight distances for individual East Atlantic Light-bellied Brent Geese Branta bernicla hrota at two spring staging areas in Denmark. Foraging ranges (mean ± s.d. = 53.0 ± 23.4 km2) were comparatively large, greater than reported elsewhere for this species, and habitat use revealed a high exploitation of salt marshes (64.4%), which now replace traditional fjord habitats as the most important for spring-fattening. At one site (Agero), geese had started to exploit agricultural fields (winter-sown cereals; 11.8% of the total GPS location data), and in all areas fjords were still frequently used for roosting at night. Minimum flight distances for foraging excursions at the staging sites varied considerably between individual geese (ranging from 4.64–10.14 km/day), and these were related to differences in habitat use. Geese using a high proportion of agricultural areas flew greater distances than those avoiding this habitat. Compared to historical data on the same population, these findings indicate a significant enlargement of foraging ranges and increased use of terrestrial habitats. This might reflect changes in habitat availability, and is probably related to significant declines in Common Eelgrass Zostera marina in both these areas. From a historically rather sedentary lifestyle, which centred around foraging on Zostera beds in fjord habitats, this population now feeds on scattered areas of salt marsh, and increasingly on inland winter-sown cereals, in a progressively cultivated landscape. As fjord habitats remain the preferred roosting areas (probably as a consequence of differences in perceived habitat-specific predation risk), this “terrestrialisation” of Brent Goose habitat use is associated with increased energetic costs in the form of higher minimum flight distances.
Seasonal variations in the seminal plasma composition of male goats

Este estudo avaliou as variacoes mensais proteicas e bioquimicas no plasma seminal de bodes da raca Alpina criados em clima tropical. A avaliacao da motilidade progressiva de espermatozoides foi realizada no semen fresco e descongelado, e a avaliacao da funcionalidade da membrana apos a descongelacao. Apos 12 meses, o plasma seminal foi submetido a eletroforese em gel de SDS-poliacrilamida a 10 e 14%, em paralelo com as analises dos seus parâmetros bioquimicos. No gel de poliacrilamida a 10% foram identificadas 22 bandas proteicas (25-181 kDa), enquanto que no gel de 14%, foram identificadas 16 bandas proteicas (5,7-165 kDa). As fracoes de proteinas de 5,7 e 34,3-34,5 kDa mostraram um perfil que variou de acordo com a sazonalidade reprodutiva dos bodes, com o aumento da producao ocorrendo durante a estacao reprodutiva. Na analise dos parâmetros bioquimicos, as concentracoes de calcio, fosforo, e colesterol tambem mostraram variacao sazonal. No entanto, a analise da motilidade progressiva, bem como a funcionalidade de membrana nao alteraram. Estes resultados indicam que alteracoes nos perfis proteico e bioquimico do plasma seminal durante o ano, nao alterou a qualidade do semen fresco e descongelado de bodes Alpinos em clima tropical.
Structural and Luminescence Characterization of Lithium-Borosulfophosphate Glasses Containing Dysprosium Ions STRUCTURAL AND LUMINESCENCE CHARACTERIZATION OF LITHIUM-BOROSULFOPHOSPHATE GLASSES CONTAINING DYSPROSIUM IONS

Rare earth doped glasses have been a great deal of research interest due to their prominent applications in laser lighting technology. However, achieving highly efficient yellow light emission from these materials require the collective efforts of many researchers across the world. Hence, a series of high optical quality dysprosium doped lithium-borosulfophosphate glasses with chemical composition of 15Li2O-30B2O3-15SO3-(40x)P2O5-xDy2O3 (where x = 0.1, 0.3, 0.5, 0.7 and 1.0 in mol%) were prepared by convectional melt quenching technique and characterized by X-Ray diffraction (XRD), Fourier Transform Infrared (FTIR) and Photoluminescence (PL) measurements. XRD pattern of the host glass confirms its amorphous nature while the results from FTIR spectra analysis indicates the presence of BO3, BO4, PO4 and SO4 groups in the host network structure. The photoluminescence spectral analysis revealed three emission bands at 494 nm, 585 nm and 673 nm attributed to the electronic transitions of F9/2→H15/2, F9/2→H13/2 and F9/2→H15/2,respectively, under the excitation of 386 nm. Among all the prepared glass samples, 1.0 mol% Dy3+ contained glass sample exhibits an intense yellow emission at 585 nm which specifies its prospective suitability for yellow laser applications.
Hemodialysis Access Choice: Impact of Health Literacy

Background: Hemodialysis patients need to make decisions about vascular access and diet that they may not fully understand. In this study, we hypothesized that patients with low health literacy are likely to choose a central venous catheter (CVC) and have higher serum potassium (K), serum phosphate (P), and inter-dialysis weight gains (IDWG). Objective: Primarily, the study sought to describe the health literacy of patients treated with hemodialysis in a Canadian tertiary care center. The secondary objective was to describe the association between health literacy and permanent vascular access choice, hyperkalemia, hyperphosphatemia, and IDWG. Methods: Adult patients receiving hemodialysis for more than 6 months were included. Health literacy was assessed with the Newest Vital Sign (NVS) test. Vascular access type and reasons for CVC use were determined. Serum K, P, and IDWG were collected retrospectively for 6 months. Student's t test and logistic regression were used to determine the association between health literacy (NVS score < 4 versus ≥ 4) and CVC choice, hyperkalemia, hyperphosphatemia, and high IDWG. Key Results: Fifty-six patients were involved. The average NVS score was 2.9. Overall, 66% of the patients had a CVC; one-third had chosen this access themselves. Poor control of K, P, and IDWG was experienced by 27%, 55%, and 36% of patients, respectively. The average NVS score was lower for patients choosing a CVC (p = .001), but not different for those with higher K, P, or IDWG. None of the patients who chose a CVC had adequate health literacy (NVS ≥ 4). Conclusions: Patients with low health literacy, who are eligible for both surgically created vascular access (fistula or graft) and CVC, are more likely to refuse fistula/graft creation compared to patients with adequate health literacy. Different educational strategies for such patients may help in appropriate decision-making. [Health Literacy Research and Practice. 2017;1(3):e136–e144. ] Plain Language Summary: This study suggests that more than one-half of patients who receive hemodialysis may not understand all the information provided by their health care team. Despite a higher risk of complications with a central venous catheter, patients with lower health literacy prefer the catheter over fistula as their blood access for hemodialysis. We need to explore patient education to ensure that information is easy to understand.
Determining behaviour of maize genotypes and growing environments using AMMI statistics

Thirty three maize genotypes including hybrids and pure lines were evaluated to assess the grain yield performance under four environments; normal nitrogen (NN 120 kg ha -1 ), high nitrogen (HN 160 kg ha -1 ), low nitrogen (LN 80 kg ha -1 ) and excess water (EW). Environment wise analysis revealed significant variance for grain yield. Analysis of data across the environments using additive main effect and multiplicative interaction (AMMI) statistics revealed significant variance for genotypes, environment and genotype x environment (GxE) interaction. Genotype main effects had the largest contribution (55.23%) to the total sum of square for grain yield followed by GxE interaction (22.73%) and environment (22.02%). The interaction component was further divided into three interaction principal component axes (IPCAs), IPCA I, IPCA II and IPCA III which accounted for 45.24%, 29.60% and 25.16% of GxE interaction component, respectively. The AMMI 1 biplot analysis using genotype main effect and IPCA I scores indicate that genotypes had high variance compared to the variance due to environments as evidenced by the distribution as well position occupied by the 33 hybrids and 4 environments on biplot display. The AMMI 2 biplot analysis identified three hybrids SCH-10, SCH-21, SCH-19 with relatively stable performance across the environments. AMMI 2 biplot analysis also categorized hybrids specifically adapted to NN, LN, HN and EW environments. However, all the hybrids exhibited specific adaptability to LN and EW environments having lower grain yield than the average yield. The inbred lines identified to have stable performance across the environments were IL-5 and IL-10, however it is interesting to note that none of the inbred lines exhibited specific adaptability to NN and HN environments which may due to inherently poor nitrogen use efficiency of inbred lines in comparison to hybrids.

Performance of radar absorbing nanocomposites by waveguide measurements

Sol-gel synthesis has been investigated in order to produce stoichiometric compositions of Ba3Co2Fe24O41 (Co2Z) at lower calcination temperatures, using citric acid as quelant complex. Using this method, Co2Z ferrite could be synthesized at 950 °C, about 400 °C lower than that of conventional method. Nanocomposites (80:20% weight) of this ferrite with polychloroprene (CR) were obtained for the microwave absorption measurements by mixing, molding and curing mixtures of Ba3Co2Fe24O41 powders with polychloroprene and the additives of vulcanization. The microwave absorption measurements was carried out using the Transmission/Reflection method for the S and X-Ku bands and showed the best performance as Radar Absorber Material (RAM) in 8.0-16.0 GHz range. Thus, the material can be used by reducing the radar signature of the Brazilian Frigates' superstructures.
HUMANIZING CLINICAL DENTISTRY THROUGH A PERSON-CENTRED MODEL

The clinical approach in dentistry stems from a biomedical model of health that is anchored in positivism. This biomedical model was never explicitly developed or reflected on, but rather implicitly acquired as a product of historical circumstance. A reductionist understanding of health served dentistry well in the past, when health afflictions were mostly acute. Today, however, in the age of chronic illnesses, the current clinical approach is no longer adequate: patients and dentists are both dissatisfied, and there are problems with dental education and dental public health. After a thorough review of the literature, highlighting the current state of the profession, we propose an alternative clinical model upon which updated approaches can be based. We call this model "Person-Centred Dentistry". Our proposed model is rooted on the notion of sharing of power between the dentist and the patient: a sharing of power in the relationship and epistemology. This leads to an expanded understanding of the person and the illness; a co-authoring of treatment plans; and interventions that focus not only on eliminating disease but also on patient needs.
Research of Dynamic Inter-relationship between Firm Growth and Profitability: A Case of Manufacturing Listed Companies

In this paper, we tried to explore the dynamic relationship between firm growth and profitability. For the purpose, we designed two testable models and collected data of manufacturing firms that listed on the Shanghai stock market from fiscal years 2003 to 2013. The results of the unit-root test showed that profitability at time t-1 had a positively significant effect on current profit rate. However, profit rates at times t-2 and t-3 were negatively significant. Through analyzing the models, we found that firm growth has a positive impact on the profitability, the increase of current equity and total assets would be helpful to the improvement of profitability, the prior year‟s (time t-1) too much assets and current high financial leverage would impede firm‟s current profitability. The prior year‟s growth rates had a negative effect on current firm growth rates, meanwhile, firm profitability may not has any impact on firm growth rates. The equity and total assets are the major factors to promote firm growth and improve profitability.
