Numerical investigation of laminar convective heat transfer for TiO2/water nanofluids using two-phase mixture model (Eulerian approach)

Laminar convective heat transfer of TiO2/water nanofluids flowing through in tube has been studied numerically using a CFD code (ANSYS Fluent Release 14.5). 2D axisymmetric configuration was applied to a horizontal circular straight tube with 2000 mm in length and 4.0 mm in inner diameter. Semi-Implicit Method for Pressure-Linked Equation (SIMPLE) was performed to couple the pressure and velocity. The convergence of the iterative solution was carefully monitored less than 10−4. The temperature distributions of nanofluids flow at Reynolds number of 900 and 1500 were mapped for a circular tube subjected to constant wall heat flux boundary conditions of 4000 W/m2. By considering the mean temperature of nanofluids, the two-phase mixture model using Eulerian approach was performed to analyze numerically convective heat transfer for titania nanoparticle concentrations of 0.24, 0.60, 1.18 vol.%. The well-known Shah and London equation was used to validate this numerical study at developing laminar flow regime. The computed numerical data has a better agreement with the prediction from Shah-London correlation rather than the centerline temperature. The results show that the two-phase mixture model using Eulerian approach considering the mean temperature has succeeded to evaluate accurately.Laminar convective heat transfer of TiO2/water nanofluids flowing through in tube has been studied numerically using a CFD code (ANSYS Fluent Release 14.5). 2D axisymmetric configuration was applied to a horizontal circular straight tube with 2000 mm in length and 4.0 mm in inner diameter.

Nitrate uptake kinetics in streams: Is carbon the driver?

The underlying mechanisms driving the coupled interaction of organic matter quantity and uptake of inorganic nitrogen are not well understood, particularly in surface waters. To determine the relationship between background dissolved organic carbon (DOC) quantity and nitrate (NO3-) uptake kinetics in streams, a series of NO3TASCC additions were performed in four sites within the Lamprey River Watershed, New Hampshire, with a wide range in background DOC concentrations (1 mg C/L 8 mg C/L). Experiments were performed between the 2013 and 2014 growing seasons. Across all sites and experimental dates, ambient and dynamic uptake velocity (Vf) correlated negatively with NO3concentrations and positively with increasing DOC concentrations and DOC:NO3ratios. Ambient NO3Vf was unrelated to pH, SUVA, PAR, temperature, and dissolved oxygen. Although there are general tendencies across the Lamprey River Watershed, individual sites behave differently in their uptake kinetics. Variation in uptake kinetics consisted of saturation and efficiency loss models, hysteresis, undetectable uptake, and increasing Vf with higher NO3concentrations (biostimulation model). NO3uptake dynamics in the Lamprey River Watershed are most influenced by DOC concentrations rather than NO3concentrations or physico-chemical parameters. Understanding the fundamental relationship between organic matter and inorganic nutrients will be important as global and climatic changes influence the delivery and production of DOC and NO3in aquatic ecosystems.
The role of Working Memory, Processing Speed and Approximate Number System abilities in low maths achievement among preschoolers

This study examined the contribution of working memory (WM) above and beyond other domain general (e.g., processing speed; PS) and domain specific abilities (e.g., Approximate Number System; ANS) for mathematical performance in low achieving (LA) preschool children. Pre-schoolers aged 3 to 5 years (N = 139) were included in the study. Children performing below the 35th percentile on a Test of Early Mathematical Abilities (TEMA-3) were considered LA and at potential risk for later mathematical learning difficulties (MLD). First, the relationships between measures of simple and central executive visuospatial and verbal WM tasks (forward, backward, and dual processing tasks), ANS, PS abilities and early mathematical abilities were explored. Then, the contribution of these measures in predicting low mathematical performance was examined in several stepwise logistic regressions. The results showed that all measures were significantly correlated, and that ANS alone explained only a smaller amount of variance in low maths achievement. Surprisingly, PS did not contribute to prediction of low maths achievement and when visuo-spatial and verbal WM measures were added to the analyses they alone explained variance to a large degree. We concluded that central executive WM and particularly backward processing ability seems to play an important role in the development of mathematical abilities in LA preschool children. Results were discussed in relation to research on WM, executive functions (EF), and early mathematical development. Conclusions for early screening and intervention in preschool were also drawn.
Diclofenac transdermal patch versus the sustained release tablet: A randomized clinical trial in rheumatoid arthritic patients

Purpose : To prepare and characterize transdermal films of diclofenac diethanolamine as a safer and more effective alternative than the sustained release (SR) tablet equivalent for prolonged relief from pain and inflammation in arthritis. Methods: Transdermal films of diclofenac were prepared using sodium carboxymethyl cellulose and polyvinyl pyrrolidone K30, with turpentine oil and sesame oil as penetration enhancers. The films were characterized for physicochemical properties and for ex vivo permeation in a randomized clinical trial (RCT) for analgesic activities in arthritic patients. Results: The transdermal films were uniform in weight and thickness, flat, with high drug content (94.40 ± 1.04 to 98.62 ± 1.08 %) and with high folding endurance (149 ± 9.09 to 192 ± 10.12). Drug permeation through excised rat abdominal skin was prolonged. Films containing penetration enhancers showed higher ex vivo drug permeation than those without the enhancer; furthermore, drug permeation increased with increase in the concentration of enhancer. The films were non-irritating to the skin. In RCT, F3 (containing turpentine oil, 1 %v/w) decreased the pain score from 9.87 ± 1.14 to 4.94 ± 0.78 units, compared with the SR tablet (once daily) which decreased pain from 9.59 ± 0.42 to 6.49 ± 1.20 units, 48 h post-administration. Turpentine oil showed better permeation enhancement than sesame oil in the transdermal films. Conclusion: Transdermal films of diclofenac, formulated with permeation enhancers, may have greater therapeutic advantages over conventional oral tablets in terms of prolonged release and improvement of patient compliance in rheumatoid arthritis. Keywords : Analgesic activity, Diclofenac, Permeation enhancer, Rheumatoid arthritis, Transdermal films
Effects of Bacillus licheniformis derived-protease supplementation, alone or in combination, with valine to low protein diet on growth performance and carcass quality grade in growing-finishing pigs

ABSTRACT This study was conducted to evaluate the effects of dietary supplementation of Bacillus licheniformis derived-protease, alone or in combination with valine to low protein diet on growth performance, nutrient digestibility and carcass quality grade in growing-finishing pigs. A total of 180 crossbred ([Landrace × Yorkshire] × Duroc) growing pigs with an initial body weight of 22.56 ± 1.59 kg were used in a 17-week feeding trial. Pigs were randomly allotted into three treatments: CON, basal diet; PROT, low protein diet with 0.05% protease; PROTV, PROT diet with 0.08% valine. During the finishing phase (wk 7–17) and overall period (wk 0–17), gain: feed (G:F) ratio was increased (P < 0.05) in pigs fed the PROTV diet compared with those fed the CON diet. Although the supplementation of B. licheniformis derived-protease in combination with valine to low protein diet increased the G:F ratio of finishing phase and overall, compared with CON, other indexes of growth performance, nutrient digestibility and carcass quality grade were not impacted. Dietary supplementation with a combination of B. licheniformis derived-protease and valine in a low crude protein diet had no deleterious effects on growth performance, nutrient digestibility and carcass quality grade in growing-finishing pigs.

The Millennials' Energy Efficiency Behaviour towards Eco-friendly Home

Having an environmentally friendly and energy-efficient house is a critical requirement today as this has a positive impact on residents and the surrounding environment, which supports the improvement of the three main pillars of the concept of sustainable development. However, many factors influence the energy-saving behaviour of households, especially the millennial generation. This study aims to identify and analyse the millennial generation's behaviour towards energy efficiency activities in environmentally friendly houses using the Theory of Planned Behaviour. The quantitative method was applied with a cross-sectional survey method and analysis with structural equation modelling. The respondents were 200 millennials in Malang and Surabaya with purposive random sampling. The analysis resulted that attitudes have a positive effect of 0.22, subjective norms have a positive effect of 0.44, and perceived behavioural control has a positive effect of 0.19 on the energy efficiency intention. The results also showed that perceived behavioural control and energy efficiency intention partially have a positive effect of 0.61 on energy efficiency behaviour. Based on the analysis and hypothesis testing results, it is concluded that subjective norm and attitudes positively and significantly affect the millennial generation's energy efficiency intention, besides perceived behavioural control. Thus, this study will support the sustainable development stakeholders so that it will lead to understanding the millennials' behaviour and reasons for safe energy in eco-friendly homes concerning appropriate energy usage rules.
The Relation of Therapist Behaviors to Treatment Engagement and Outcomes in PCIT

Parent Child Interaction Therapy (PCIT) has proven to be a very effective treatment for child behavioral problems, however, PCIT does not benefit all families equally, presumably at least partly because therapists may not be equally effective in coaching their clients. Although researchers have proposed several dimensions of therapist coaching behaviors that are considered desirable, few of these have been empirically examined in relation to family engagement or child outcomes. Data from two clinical trials examining the effectiveness of culturally modified versions of PCIT (GANA and PersIn), were used to investigate which of several therapist coaching behaviors (brevity, positivity, consistency, accuracy, directive coaching and responsive coaching) are related to faster parent skill acquisition, treatment retention, and child outcomes. The findings indicate that none of these skills were significant in predicting speed of parent skill acquisition or parent reported improvement in child symptoms. However, positivity and responsiveness were significant predictors of treatment completion, while therapist directiveness was significantly related to treatment dropout. These findings suggest that these three therapist behaviors are particularly important to treatment engagement for both Spanish and English speaking families and should be important targets for therapist training.

Overcoming the Void: Obstacles to Authentic Culturally Relevant Teaching

This study explored how teacher perceptions of professional development (PD) on culturally relevant teaching (CRT) and a lack of student voice impede authentic implementation of CRT. Culturally relevant teaching involves utilizing student backgrounds and voices to shape curriculum and pedagogy. However, a review of the literature revealed that student voice is largely missing in CRT research. Additionally, teacher responses to PD were not frequently discussed in studies exploring implementation of CRT. The purpose of the study was to better understand student desires for education and teacher responses to PD on CRT. Research was conducted at a 7-12 public school in Northern California. Four teachers and three students were interviewed, and two students participated in a focus group. After analysis through coding, narrative analyses, and analytic memos, the findings suggested there was a void between teacher’s understanding of CRT and student desires for what CRT should include in the classroom. While students and teachers had similar understandings of the meaning of CRT, students desired more representationally diverse academic content and recurrent lessons on social emotional learning. An additional void in communication appeared to exist between teachers and administration regarding the perceived effectiveness of the mandatory school-wide CRT training. Two teachers had negative reactions to the PD and did not feel comfortable sharing their frustrations with administration. Overall, findings suggest that schools should create more explicit avenues for students to share their desires and feedback with staff. Additionally, training on CRT should take place through bottom-up PD rather than a top-down approach.
Common basil (Ocimum basilicum L.) responses to lead (Pb(NOз)2) stress: Germination, morpho-physiological, and phytochemical

The negative impact of contaminated soil with heavy metals on plant and human health is an important global concern. To evaluate the effect of lead (Pb(NOз)2) stress (0, 25, 75, 100, and 150 µM) on the germination, growth, physiological, and biochemical of sweet basil (Ocimum basilicum L.), a pot experiment based on completely randomized design (CRD) with three replicates was conducted at the Department of Horticultural Science, Shahed University of Tehran, in 2018. The contaminated soil with Pb had a negative impact on germination indices (percentage and rate), growth and morphological parameters (shoot and root length and dry weight), and physiological parameters (LAI, photosynthetic pigments, and number of leaf secretory glands). Pb stress (150 µM) led to a reduction in the average of germination percentage (43.33%), germination rate (62.92%), shoot and root dry weight (60.22 and 77.43%, respectively), LAI (64.68%), total chlorophyll content (73.10%), and number of leaf secretory glands (33.3%) in compared to the control treatment (without Pb), while increased peroxidase activity (62.3%), proline content (70.14%), and the root and shoot Pbcontent (92.10 and 97.6%,respectively). On the Other hand, Pb stress led to a change in the content of essential oil compounds. In general, low levels of Pb (25 µM) appear to increase the predominance of oil compounds. In conclusion, common basil cultivation in the Pb contaminated soil could cause undesirable effects on the germination indices, growth and morphological traits, and physiological attributes but might behave a positive influence under low level (25 µM) on the essential oil composition.
Screening of transition metal/oxide-impregnated ZSM-5 catalysts for deoxygenation of biomass oxygenates via direct methane intervention

ABSTRACT Removal of oxygen from biomass (deoxygenation) is a significant challenge that needs to be overcome to effectively produce hydrocarbon-based biofuel. The present technology needs extraneous hydrogen (H2) to act as a proton donor, to effectively remove this oxygen. This work is geared toward finding an effective catalyst that accommodates the direct use of methane, instead of H2, for deoxygenation reactions. Here, we studied the impact of three oxides (Ga2O3, MoO3, Cr2O3) and two metals (Pt, Ni) impregnated (at 1, 2 and 5% loadings) on ZSM-5 support on furan conversion, benzene-toluene-ethylbenzene-xylenes (BTEX) selectivity, and coke formation when furan was catalytically pyrolyzed in methane and methane-free environments. The results indicate that Ga-, Pt- and Ni-based catalysts increase BTEX selectivity in a methane environment as opposed to methane-free conditions. The type of metal and the amount of loading had a significant impact on furan conversion as well. Ga/ZSM-5-based catalyst displayed the highest BTEX selectivity, while Ni/ZSM-5 resulted in the highest furan conversion. The results are significant since there is strong evidence of select catalysts’ ability to activate methane and in turn allow furan deoxygenation. This work paves the way to use methane (or natural gas) instead of H2 as a direct proton donor for deoxygenation reactions.
Physical Attractiveness Biases Judgments Pertaining to the Moral Domain of Purity

Research on the Beauty-is-Good stereotype shows that unattractive people are perceived to have worse moral character than attractive individuals. Yet research has not explored what kinds of moral character judgments are particularly biased by attractiveness. In this work, we tested whether attractiveness particularly biases moral character judgments pertaining to the moral domain of purity, beyond a more general halo effect. Across four preregistered studies (N = 1,778), we found that unattractive (vs. attractive) individuals were judged to be more likely to engage in purity violations compared with harm violations and that this was not due to differences in perceived moral wrongness, weirdness, or sociality between purity and harm violations. The findings shed light on how physical attractiveness influences moral character attributions, suggesting that physical attractiveness particularly biases character judgments pertaining to the moral domain of purity.
