Study of Cornering Maneuvers of a Pneumatic Tire on Asphalt Pavement Surfaces Using the Finite Element Method

Field experience shows that most road accidents that occur during turning maneuvers are caused by the loss of vehicle control. The loss of vehicle control is often related to a lack of sufficient friction between the tire and the pavement surface. In experiments and analytical studies, the overall antiskidding performance of a pneumatic tire has been observed to be affected by operating conditions, road texture, and surrounding temperatures. Interactions of these parameters create a complex relationship between their combined effect and the tire's ability to combat skidding. One way to analyze the cornering maneuvers of a vehicle is by means of a validated finite element tool that can carry both the tire and the pavement properties. Few computational studies have been conducted to study the cornering performance of a rolling pneumatic tire, and none of these studies included the role of pavement surface morphologies in their analysis. In this study, a thermomechanical framework was used to analyze the influence of temperature on cornering friction. The cornering friction coefficient was found to decrease with an increase in the loads and the speeds. The cornering friction coefficient was found to increase with an increase in inflation pressure, sideslip angle, and pavement surface texture depth. The proposed study contributes to an understanding of the cornering performance of passenger car tires.

Environmental Impacts Associated with Intensive Production in Pig Farms in Mexico through Life Cycle Assessment

In this research, environmental impacts associated with the intensive production of pigs on a farm in Mexico were determined through the application of life cycle assessment methodology. The research was focused on the following stages of the product system: (i) pig rearing and growth phases; (ii) production operations in the pig-house; (iii) the supply of feed. The life cycle inventory database was mainly made up of data collected in field visits to local farms. The functional unit was defined as one finished swine weighing 124 kg. The results for the selected impact categories of carbon, water, and energy footprints were 538.62 kg CO2eq, 21.34 m3, and 1773.79 MJ, respectively. The greatest impact was generated in the final stages of pig fattening, mainly due to the large quantity of feed supplied. The impacts caused by operation of the pig farm were less significant, their contribution in all cases was less than a third of the total quantified values. The energy conversion of pig slurry improves the environmental performance of the product system by reducing the carbon footprint.
Numerical Analysis on the Evolution of NH2 in Ammonia/hydrogen Swirling Flames and Detailed Sensitivity Analysis under Elevated Conditions

ABSTRACT Ammonia/hydrogen blends have received some attention toward the development of new technologies focused on gas turbine combustion systems, as doping of hydrogen in ammonia enhances flame speed and stability while decreasing ignition energy. One of the challenges of these blends relies on the appropriate computational modeling of their combustion properties in combination with the complex hydrodynamics inherent to flow control techniques such as swirling flows, which are known to be the main method of flame stabilization in current gas turbines. Moreover, it is well-known that large reaction kinetic models are difficult to employ in these computational analyses, thus increasing the difficulty of obtaining reliable methods for the design of new combustors. Therefore, this research analyses a reduced chemical reaction mechanism, namely Okafor’s mechanism, comparing its performance and accuracy against obtained experiments. Emission measurements and non-intrusive laser techniques (LDA) were employed to validate models running on CHEMKIN-PRO flow reactors and RANS Complex Chemistry. Once validated, the study identified the main contributors and reaction kinetics of NH2 and NO consumption, hence evaluating the process via production rates and sensitivity analysis of various important reactions. The results depicted positive correlation between NH2 formation and heat release, N2, H2O, N2O, NH, NNH, NO, O formation, whereas NH3, N2H3 and NO2 have shown negative correlation. Statistical correlations supported these findings but unfortunately were inconclusive to the impacts of vorticity and turbulence over the production/consumption of amidogen. Sensitivity analysis has shown NH2 radicals and atomic N to be the main contributors of NO formation in the flame zone, although most of the NO formed in the flame zone shown to be consumed at the post-flame zone due to the presence of NHx radicals and atomic N.

Branding Co-Creation with Consumer-Generated Advertising: Effect on Creators and Observers

Abstract Of the social media tools available to brand managers, consumer-generated advertising (CGA) has attractive features combining consumer-generated content, social media advertising, and online interactive marketing campaigns. However, only a small number of customers actively participate in co-creation of CGA. Based on social presence theory and service-dominant logic conceptualization, we examined CGA observers, knowledgeable and attentive viewers of value co-creation processes who do not directly participate in value co-creation. In two studies, we examined consumer responses to company-driven CGA and found no significant differences between CGA creators, or direct participants, and CGA observers, or indirect participants in the process of involvement with CGA, its antecedents, and its outcomes. Study 1 demonstrated that CGA observers developed positive attitudes toward co-created CGA that influenced their brand loyalty and willingness to participate in the process. Study 2 revealed that both creators’ and observers’ involvement with CGA led to stronger perceptions of competitive advantage, which positively affected brand loyalty and trust. Perceptions of competitive advantage also had a mediation effect.
The role of cognitive activation in predicting mathematics self-efficacy and anxiety among internal migrant and local children

Abstract The primary goals of this study are to investigate if cognitive activation increases mathematics self-efficacy, which in turn alleviates anxiety and to examine the moderating role of internal migrant status. Hierarchical linear models and multilevel structural equation models were employed to datasets of 3088 fourth graders from 57 classrooms in China. The moderated effect and the moderated mediation effect of cognitive activation at both the student and classroom levels were tested. Results show that: (a) cognitive activation was positively associated with mathematics self-efficacy and negatively associated with mathematics anxiety; (b) the association of cognitive activation with mathematics self-efficacy and anxiety was stronger in classrooms with more internal migrant children and (c) mathematics self-efficacy mediated the relationship between cognitive activation and mathematics anxiety.
Can assessment-specific marking criteria and electronic comment libraries increase student engagement with assessment and feedback?

Abstract Student frustration with the level and content of feedback is well-noted, especially in relation to new or unfamiliar assessment types. At the same time, students are often unlikely to engage with marking and feedback processes, including the use of rubrics or marking criteria before submission. The aim of this project was to build students’ assessment and feedback literacy through engagement sessions both before and after submission in two departments at a UK university. Following discussions with students on their perceptions of feedback, assessment-specific marking criteria were developed. Students were provided with an opportunity to discuss these criteria and assess exemplars before submission and then, after return of marks, discussed the helpfulness of the feedback provided. Feedback Studio® was used to provide electronic feedback via comment libraries, general comments and qualitative rubrics. Both staff and students found that the combination of engagement sessions and online feedback was a positive improvement, although questions were raised about the timing and frequency of engagement sessions and students’ ability to apply marking criteria to their own work. The conclusions summarise recommendations for the use of timetabled engagement sessions to support students in the use of assessment-specific marking criteria.
Novel Polyimide-block-poly(dimethyl siloxane) copolymers: Effect of time on the synthesis and thermal properties

Polyimide-block-poly(dimethyl siloxane) copolymer was synthesized by a two-step process, initiated by coupling anhydride terminated poly(amic acid), AT-PAA with amino terminated poly(dimethyl siloxane), (NH2)2-PDMS to form poly(amic acid)-block-poly(dimethyl siloxane). The resulting copolymer is then thermally treated to produce polyimide-block-poly(dimethyl siloxane), PI-PDMS. Because of the high glass transition temperature, Tg of polyimide, it is usually cured at a high temperature of about 300°C for over 2.5 h. Copolymerization of polyimide with polysiloxane, reduces the imidization temperature while maintaining high thermomechanical properties. A series of instruments were used to monitor the progress of copolymerization. The time-based analysis of the product of copolymerization enables the optimization of the structure and properties of the copolymers. The chemical structure and composition of the copolymer were studied by Fourier Transform Infrared Spectroscopy, (FT-IR). The incorporation of PDMS blocks into the copolymer and the degree of imidization of the polyimide block increased with increasing reaction time. The change in the viscosity of the copolymerizing solution was monitored by simple shear viscometry conducted with the Brookfield Viscometer. The reported increase in solution viscosity with increasing copolymerization time is associated with increasing molecular weight of the copolymer. The intrinsic viscosity of the copolymer solution was measured as a function of copolymerization time and it was found that the intrinsic viscosity of the copolymer solution increased with increasing reaction time. The glass transition temperature (Tg) and the thermal stability of the copolymer were determined by differential scanning calorimetry, DSC and thermogravimetric analysis, and TGA, respectively. Between 25°C and 420°C, the copolymers synthesized in this study show two glass transition temperatures due to the polyimide, PI block at around 380°C and another peak associated with PDMS plasticized polyimide at about 290–300°C. The two Tg peaks observed in the DSC thermogram are believed to be indicative of the structure of a block copolymer. TGA analysis shows that the thermoxidative stability of the copolymers increased with increasing reaction time, due to the incorporation of increased amount of PDMS unit into the copolymer. The combination of increasing molecular weight of copolymer, higher degree of imidization of polyimide blocks and enhanced thermoxidative stability may translate into improved flame retardancy of copolymers. This suggested enhancement in flame retardancy in air atmosphere, is believed to be due the incorporated PDMS blocks, which can be converted into silica, SiO2, a recognized thermally stable material.
“The Message Is You Don’t Exist”: Exploring Lived Experiences of Rural Lesbian, Gay, Bisexual, Transgender, Queer/Questioning (LGBTQ) People Utilizing Health care Services

Background Lesbian, gay, bisexual, transgender, queer/questioning (LGBTQ) people experience significant health inequities with well-documented negative health impacts due to their status as a sexual and gender minority population. Insensitive or discriminatory attitudes toward LGBTQ people within the health care system have negatively impacted access to health services and the overall physical and mental health and well-being of this at risk population. Few studies of LGBTQ populations in rural areas have been conducted, with even fewer in the Canadian context. Rural areas often create greater visibility for LGBTQ persons, contain fewer supports and alternatives in the face of discrimination, and are often are less accepting of LGBTQ populations due to increased stigma and social isolation. Objective The purpose of this study is to examine the lived experiences of LGBTQ people utilizing health care services in rural Manitoba. Method 12 individuals who self-identified as LGBTQ who had accessed health care services in Manitoba were recruited. Using qualitative methodology, interviews were recorded and analyzed for themes. Results Analysis revealed themes including stigma and discrimination, judgments and assumptions, gender identities, lack of knowledge, limited access/systemic barriers, rural considerations, and recommendations for changes to address the gaps in health care services and barriers to access. Conclusions This study of the LGBTQ community provides an expression of their opinions and experiences, but also provides a voice to this underserved population. The findings of this study provide a better understanding of the unique health needs and experiences of LGBTQ people in rural Manitoba, creating opportunities for meaningful change in health care delivery
Relationship between quality of work-life, resilience and burnout among nursing professionals during COVID-19 pandemic in Iran: A cross-sectional study

Background The COVID-19 pandemic and the increased workload and stress associated with the disease prevalence have posed a high risk of burnout to nurses. The effects of the workplace and environmental factors on resilience and burnout among nursing professionals have not been investigated in Iran. Objective Present study aimed to assess a model linking quality of work-life to the resilience and various dimensions of burnout among Iranian nursing professionals based on the health service workplace environmental resilience model. Methods This was a cross-sectional study performed on 202 Iranian nurses employed in three educational hospitals. Maslach burnout inventory, Brooks’ quality of nursing work-life survey, and an abbreviated version of the Connor-Davidson resilience scale were used to collect data. The correlation between the study variables was assessed by conducting path analysis in AMOS 22. Results The final model demonstrated adequate fit. The quality of working life indirectly affected burnout via a direct impact on nursing professionals’ resilience (p <0.001, β = 0.39). In addition, resilience had negative, significant effects on all the dimensions of job burnout. The quality of work-life also had negative and significant effects on emotional exhaustion (p <0.001, β = -0.38) and reduced personal accomplishment (p <0.001, β = - 0.38). Conclusion Resilience and quality of work-life are protective variables against burnout in nursing professionals. Nursing managers can increase resilience and decrease burnout among nursing professionals by adopting policies that can improve the quality of work life.
High frequency characteristics of MCM decoupling capacitors

The increased frequency operation of CMOS microprocessors and other circuitry places severe demands on power distribution systems to supply stable, noise-free power. Particularly in MCMs, where short signal line lengths allow fast off-chip switching, improved decoupling capacitors are required for short-term charge storage to reduce dI/dt noise. This paper examines the relative parasitic contributions of off-chip connections, MCM power distribution planes, and decoupling capacitors, and the effect of these parasitics on power distribution integrity. It is shown that the effect of the inductances of chip-to-substrate interconnections can be minimized by using multiple interconnections and careful design both in a wirebond or in a flip chip environment. Similarly, the intrinsic inductance and resistance of power distribution planes, either solid, perforated, or the new IMPS (Interconnected Mesh Power System), is extremely low and does not determine the effectiveness of power distribution.
Comparison of D-dimer level measured on the third day of hospitalization with D-dimer level in predicting in-hospital mortality in COVID-19 patients

The present study aimed to compare the value of D-dimer measured on the 3rd day of hospitalization with admission D-dimer level in predicting in-hospital mortality in coronavirus disease 2019 (COVID-19) cases. In total, 231 patients with COVID-19 disease were included in the study. D-dimer levels were estimated using immunoturbidimetric assay with normal range of 0–500 μg/mL. In the current research, the primary outcome was the in-hospital mortality. In the present research, 39 (16.8%) COVID-19 cases died during the index hospitalization. In a multivariable analysis; age, D-dimer (3rd day) (OR: 1.00, 95% CI: 1.00–1.00, p<0.001), WBC count, and creatinine were independent predictors of the in-hospital death for COVID-19 cases. The ideal value of D-dimer level on the 3rd day of hospitalization was 774 μq/mL (area under curve (AUC): 0.903, 95% CI: 0.836–0.968; p<0.01) with sensitivity of 83.2% and specificity of 83.6%. It was noted that D-dimer level on the 3rd day of hospitalization had a higher sensitivity (83.2% vs 67.6%, respectively) and AUC value than that of D-dimer level on admission (0.903 vs 0.799, respectively). The main finding in this investigation was that D-dimer elevation on the 3rd of hospitalization is more sensitive predictor of in-hospital mortality than D-dimer elevation on admission in COVID-19 patients. Even though further investigations are needed to forecast precise prognosis in patients with COVID-19 disease in terms of D-dimer levels, we believe that D-dimer levels on the 3rd day of hospitalization have an enhanced potential to be used as a prognostic marker in routine clinical practice.

What else can a crush become: working with arts-methods to address sexual harassment in pre-teen romantic relationship cultures

ABSTRACT This article focuses on a study in which feminist new materialist and arts-based methodologies were employed to explore how three girls address their experiences of sexual harassment as part of ‘crushes’ with boys in fourth and fifth grade. The study stems from longitudinal research on how Finnish children from pre-school to pre-teen years are caught up in entanglements of power in the formation of romantic relationship cultures. Such entanglements often escape articulation and are therefore difficult to study using more traditional research methods. During the arts-based process, the girls began to negotiate consent and self-determination in new ways through collecting, crafting, and making a booklet and a YouTube video. Conceptualising the changes as minor gestures [Manning, Erin. 2016. The Minor Gesture. Durham, NC: Duke University Press] that gradually transform girls’ somatic archives [Paasonen, Susanna. 2013. “Grains of Resonance: Affect, Pornography and Visual Sensation. ” Somatechnics 3 (2): 351–368. doi:10.3366/soma.2013. 0102], we argue that arts-methods can empower children to relate differently to each other, refuse harassment and assert their desires.
Fertilizer N- and P-rates Response on sunflower intercropping with Mungbean in North-West, Pakistan

Intercrop mungbean in sunflower may increase yield, improve soil quality and use the resources (e.g. air, water and light) more efficiently. We, therefore, compared mungbean intercropped in sunflower by increasing N and P fertilizer rates. The given fertilizers rates were 30, 60, 90 kg ha -1 each for N and P 2O5 including a control treatment (no N and P fertilizer) as sole sunflower, mungbean and their intercropping in spring 2011 and 2012. The experiment was conducted in randomized complete block design with split plot arrangement at Agronomy Research Farm, the University of Agriculture Peshawar, Pakistan. Results revealed that grain yield (kg ha -1 ) of sunflower crop did not differ as sole or intercrop but did reported higher for mungbean as sole than intercrop which were due to healthier traits of the mungbean crop as sole than intercrop. Fertilized than control obviously showed better yield and yield traits of both sunflower and mungbean. Increased N-rates from 30 to 90 kg ha -1 showed a significant (p<0.05) increase in yield of both sunflower and mungbean. This increase in yield of crops were mainly associated with increase in head diameter, grain number per head and grains weight of sunflower and likewise the pod number, grain per pod and grains weight of mungbean. Grain oil content of sunflower and nodule number of mungbean were rather adversely affected by increase in N-rate to the crops. Increase in P-rate to both crops increased grain yield with markedly increase in thousand grains weight on sunflower and mungbean. The study suggested that intercrop mungbean in sunflower than sole crop has a potential for further yield improvement of the cropping system. Research needs to identify an appropriate variety as well as species for the better soil health and future production per unit return.
