Flamelet/transported PDF simulations of ethylene/air jet turbulent non-premixed flame using a three-equation PAH-based soot production model

This article reports flamelet/transported PDF (TPDF) simulations of the well-documented ethylene/air turbulent non-premixed jet flame investigated experimentally at Sandia. The transported PDF equation is solved with the Stochastic Eulerian Field method. The soot production is modelled by a validated three equation PAH-based soot model that predicts the mean soot aggregate properties at low computational time and includes a detailed description of the soot production processes. Gas and soot radiation is modelled using the rank-correlated full-spectrum k model. The turbulence/chemistry/soot production/radiation interactions are taken into account by means of the PDF method. Simulations are run by considering or not soot differential mixing. Based on recent conclusions drawn from Direct Numerical Simulations (Zhou et al., Proc. Combsut. Inst. 38 (2021) 2731–2739), soot differential mixing is modelled by neglecting soot mixing owing to sufficiently large mixing timescales. When soot differential mixing is considered, model predictions reproduce reasonably well the exhaustive set of experimental data, including flame structure, soot statistics and radiative outputs without adjusting parameters. In particular, the predictions demonstrate for the first time the capability of RANS/TPDF models to capture the soot intermittency. On the other hand, neglecting the soot differential mixing produces notable reductions in mean and fluctuating soot volume fraction and soot intermittency. Scatter plot analysis shows that the effects of soot differential mixing are more pronounced in regions of the mixture fraction space where soot surface growth and soot oxidation dominate the soot production, affecting these processes in a non-negligible manner. In an opposite way, soot nucleation and PAH condensation are much less significantly affected. Model results show also that disregarding soot differential mixing reduces the mean soot emission as well the soot emission turbulence/radiation interaction.
Brand Management Measurement in Mexican Small Firms: Empirical Evidence

Abstract Brand management is a construct that has been recently analyzed and discussed in the marketing literature, where most empirical studies have made an emphasis on big transnational enterprises and only a few studies have focused on the analysis and discussion of brand management in small firms, even when this sector is the biggest one in any country as it represents around 90% of all the enterprises in the planet, they employ around 50% of all the labor force and they are main driving force of development of the economy of countries. That is why the main objective of this empirical research is the analysis and discussion of brand management in small enterprises from a country of emerging economy, as it is the case of Mexico, by using a sample of 300 small firms and applying a structural equations models that can allow more deeply the existing relation among the dimensions of brand management. The results obtained show that the four dimensions of brand management (values, norms, artifacts and behaviors) are closely related among them and they are excellent indicators for the measurement of brand management in small firms.

Meta-Analysis of the Effects of Organic Chromium Supplementation on the Growth Performance and Carcass Quality of Weaned and Growing-Finishing Pigs

Simple Summary During pig production, organic chromium is usually added to the feed to supplement the chromium needed for pig growth and metabolism. However, different types of organic chromium have different effects on the addition period and dosage. Therefore, the purpose of this study is to analyze the effect of adding organic chromium in pig feed by means of meta-analysis. The results show that organic chromium can improve the average daily gain and average daily intake of pigs. At the same time, the effect of adding in the weaning stage is better than that in the growing and finishing stage. Abstract Many factors influence the effects of exogenous organic chromium (EO-Cr) on the growth performance and carcass qualities of weaned and growing-finishing pigs, such as pig growth stages, types of EO-Cr, period of supplementation, and farm management. However, it is challenging to comprehensively consider all factors in one study. To solve this problem, we searched all relative literature published from 1 January 2000 to 1 January 2023, to systematically analyze and review the effects of EO-Cr on pig growth performance and carcass qualities via meta-analysis. Thirty-five papers were filtered and analyzed, which involved 4366 pigs. The results showed that, for weaned piglets, EO-Cr diets significantly increased the average daily gain (ADG, p < 0.001) and average daily feed intake (ADFI, p = 0.022) but reduced the feed–gain ratio (p = 0.004). In addition, for growing-finishing pigs, EO-Cr supplementation significantly increased the ADG (p < 0.001), carcass lean ratio (p = 0.020), and loin muscle area (p < 0.001), but had no significant effect on the ADFI (p = 0.071), feed–gain ratio (p = 0.692), dressing percent (p = 0.989), or back fat thickness (p = 0.142). Moreover, the effect of EO-Cr was greater in weaned piglets than in growing-finishing pigs. In terms of the dose effect of the supplement, chromium nicotinate is the most suitable EO-Cr type for weaned piglets with an optimal dosage range of 0.125–0.150 mg/kg. On the other hand, chromium picolinate is the most suitable EO-Cr type for growing-finishing pigs with an optimal dosage range of 0.250–0.300 mg/kg. In conclusion, EO-Cr supplementation is beneficial for enhancing the growth performance and carcass qualities of both weaned and growing-finishing pigs.
CATEGORY SHIFTS IN TRANSLATING ENGLISH COMPLEX NOUN PHRASES IN UGLY LOVE NOVEL INTO INDONESIAN

English noun phrases can be categorized into simple and complex noun phrases. Whether or not a noun phrase is complex, it can be seen from the structure of a noun phrase that has a pre-modification, head, and post-modification or its complementation. However, when it is translated into Indonesian, the shifts happen. In translations, there are two types of shifts. They are level shifts and category shifts. This research is aimed at finding out the complex noun phrases in a novel entitled Ugly Love and their category shifts of translation in Indonesian. A descriptive qualitative method was applied in this research. Based on the findings, there are 41 Complex Noun Phrases found. However, there are six (6) Complex Noun Phrases that are translated using category shifts. Two (2) data are translated using structure shift and unit shift. One (1) data is translated using unit shift. One (1) data is translated using unit shift and class shift. Two (2) data are translated using structure shift, class shift, and unit shift. It reveals that the most dominant used of category shift is unit shift, followed by structure shift. Furthermore, the least used of category shift is class shift. In addition, intra-system shift was not found because the nouns mentioned in the data findings are all singular nouns.

Neurological and Neurocognitive Impairments in Adults with a History of Prenatal Methylmercury Poisoning: Minamata Disease

Minamata disease, which happened during the 1950s and 1960s in Minamata, Japan, is a well-known case of food poisoning caused by methylmercury-contaminated fish. Although many children were born, in the affected areas, with severe neurological signs after birth (known as congenital Minamata disease (CMD)), few studies have explored the possible effects of low-to-moderate methylmercury exposure in utero, probably at lower levels than in CMD patients, in Minamata. We, therefore, recruited 52 participants in 2020: 10 patients with known CMD; 15 moderately exposed residents; and 27 non-exposed controls. The average umbilical cord methylmercury concentrations were 1.67 parts per million (ppm) for CMD patients and 0.77 ppm for moderately exposed participants. After conducting four neuropsychological tests, we compared the functions among the groups. Compared with the non-exposed controls, both the CMD patients and moderately exposed residents had worse scores in the neuropsychological tests, although the score decline was more severe in the CMD patients. For example, even after adjusting for age and sex, the CMD patients and moderately exposed residents had 16.77 (95% CI: 13.46 to 20.08) and 4.11 (95% CI: 1.43 to 6.78) lower scores in the Montreal Cognitive Assessment, respectively, than the non-exposed controls. The present study indicates that residents of Minamata who experienced low-to-moderate prenatal methylmercury exposure also have neurological or neurocognitive impairments.

Modern supplementary strategies of filling material removal in non-surgical root canal retreatment

O retratamento não cirúrgico é atualmente a terapia mais afetada na Endodontia em termos de desfecho clínico. O presente estudo tem como objetivo avaliar estratégias modernas para abordagens complementares na remoção de material de obturador. Assim foi realizada uma revisão narrativa da literatura nas bases de dados PubMed. Cochrane Library e Web of Science com as seguintes palavras-chave em diferentes ordens: “root canal”, “filling material removal”, “non-surgical retreatment” e “supplementary”. Para o delineamento da seleção de estudos, após a triagem dos títulos, foi realizada a retirada das duplicatas e aplicados os critérios de inclusão, em seguida foi feita a análise dos resumos e, por fim, realizada a revisão dos textos completos para seleção final dos estudos. Pesquisas adicionais foram conduzidas manualmente sob demanda. Seis tipos de estratégias de limpeza foram identificados na literatura para abordagem complementar em retratamento não cirúrgico: ativação ultrassônica e sônica passiva, ativação ultrassônica ativa, instrumentos plásticos para agitação mecânica, instrumentos metálicos para agitação mecânica, ativação multissônica e ativação a laser. Aqueles abordados na literatura têm sido associados a desempenhos mais elevados de remoção de material de obturador em comparação com sistemas de instrumentação apenas. No entanto, nenhum deles foi capaz de remover completamente o material obturador dentro do sistema de canais radiculares. Estudos clínicos controlados e randomizados são necessários para entender a real influência dessas estratégias no retratamento não cirúrgico. Há uma discrepância notável entre o volume de estudos para cada estratégia, mais estudos são necessários em alguns sistemas já contemplados. Ainda existem sistemas de ativação das soluções irrigadoras não elucidados no retratamento não cirúrgico.
Antiproliferative Activity and Impact on Human Gut Microbiota of New O-Alkyl Derivatives of Naringenin and Their Oximes

Naringenin is a 5,7,4′-trihydroxyflavanone naturally occurring mainly in citrus fruits, characterized by a wide spectrum of biological activity. Chemical modifications based on alkylation and oximation in most cases increase its bioactivity. The aim of our research was to evaluate the antiproliferative activity and influence on selected representatives of the human gut microbiota of new synthesized O-alkyl derivatives (A1–A10) and their oximes (B1–B10), which contain hexyl, heptyl, octyl, nonyl and undecyl chains attached to the C-7 or to both the C-7 and C-4′ positions in naringenin. To the best of our knowledge, compounds A3, A4, A6, A8–A10 and B3–B10 have not been described in the scientific literature previously. The anticancer activity was tested on human colon cancer cell line HT-29 and mouse embryo fibroblasts 3T3-L1 using the sulforhodamine B (SRB) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assays. We also determined the impacts of all compounds on the growth of Gram-positive and Gram-negative bacterial strains, such as Staphylococcus aureus, Enterococcus faecalis and Escherichia coli. The antimicrobial activity was expressed in terms of minimal inhibitory concentrations (MIC) and minimal bactericidal concentrations (MBC) values. For 7,4′-di-O-hexylnaringenin (A2), 7-O-undecylnaringenin (A9) and their oximes (B2, B9), which were safe for microbiota (MIC > 512 µg/mL) and almost all characterized by high cytotoxicity against the HT-29 cell line (A2: IC50 > 100 µg/mL; A9: IC50 = 17.85 ± 0.65 µg/mL; B2: IC50 = 49.76 ± 1.63 µg/mL; B9: IC50 = 11.42 ± 1.17 µg/mL), apoptosis assays were performed to elucidate their mechanisms of action. Based on our results, new compound B9 induced an apoptotic process via caspase 3/7 activation, which proved its potential as an anticancer agent.
Hypolipidemic effects of microencapsulated powder fraction from Hibiscus sabdariffa. L calyx in hyperlipidic rats

The lipid-lowering activity of microencapsulated and nonmicroencapsulated Hibiscus sabdariffa L. powder fractions in rats rendered hyperlipidemic by a hyperlipid diet (HLD) was determined. Dried calyces of H. sabdariffa were finely ground and fractionated on a sieve column to retain particle sizes ϕ < 315 µm, and were microencapsulated with maltodextrin (MD). Rats were randomly divided into four groups: normal control group, hyperlipid diet group (negative control groups), hyperlipid diet group supplemented with atorvastatin, non-microencapsulated (NMEPHS) and microencapsulated (MEPHS) powders from H. sabdariffa calyces groups. Rats received atorvastatin, NMEPHS and MEPHS for three weeks. Atorvastatin (10 mg/kg) and individual powders were dissolved in water and administered to rats at a dose of 250 mg/kg body weight for three weeks. Body weight, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate transferase (AST), alanine transferase (ALT), superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) were measured. Very low-density lipoprotein cholesterol (VLDL-C), hepatosomatic index (HSI), and adiposomatic index (ASI) were calculated. Lipid profil, and MDA were increased in the negative control rat groups compared with the negative control rat group. NMEPHS and MEPHS significantly reduced body weight gain, ASI, HSI, TC, TG, LDL-C, ALT, AST, and MDA and increased HDL-C level significantly. Moreover, SOD and CAT activities were reduced with HLD and significantly increased with HSCP intake. however, the most significant activities were revealed by MEPHS. These results suggest that MEPHS exerts potent lipid-lowering effects, promotes hepatic fat breakdown, and regulates antioxidant enzymes in a more efficient manner.
Speech corpus recycling for acoustic cross-domain environments for automatic speech recognition

In recent years, server-based automatic speech recognition (ASR) systems have become ubiquitous, and unprecedented amounts of speech data are now available for system training. The availability of such training data has greatly improved ASR accuracy, but how to maximize the ASR performance in new domains or domains where ASR systems currently fail (thus limiting data availability) is still an important open question. In this paper, we propose a framework for mapping large speech corpora to different acoustic environments, so that such data can be transformed to build high-quality acoustic models for other acoustic domains. In our experiments using a large corpus, our proposed method reduced errors by 18.6%.
Variance heterogeneity in experimental design

In many experiments (especially simulation experiments) the response variances ai2 differ substantially. These variances a12 can be estimated through replication (ín simulation through different random numbera seeds). The experiment can be analyzed through Estimated Weighted Least Squares, or Corrected Least Squares, which use the variance estimators ai2. Even if the design matrix is orthogonal (like in 2k p designe), the resulting estimatora of the effects s become mutually dependent. Variance heterogeneity means that classical designs are not necessarily optimal. Fortunately, optimality is not really i mportant in practice. More important is to have designs with a small number of factor-level combinations (which still yield unbiased estimators of g) , permitting validation of the linear regresaion model, and providing flexibilíty including sequential experimentation. A heuristic two-stage procedure is proposed, which com-binea classical desígns with a number of replicatione euch that the variancea are approximately conetant per average response.
The Long-Term Risk of Knee Arthroplasty in Patients with Arthroscopically Verified Focal Cartilage Lesions

Background: Focal cartilage lesions are common in the knee. The risk of later ipsilateral knee arthroplasty remains unknown. The purposes of the present study were to evaluate the long-term cumulative risk of knee arthroplasty after arthroscopic identification of focal cartilage lesions in the knee, to investigate the risk factors for subsequent knee arthroplasty, and to estimate the subsequent cumulative risk of knee arthroplasty compared with that in the general population. Methods: Patients who had undergone surgical treatment of focal cartilage lesions at 6 major Norwegian hospitals between 1999 and 2012 were identified. The inclusion criteria were an arthroscopically classified focal cartilage lesion in the knee, an age of ≥18 years at the time of surgery, and available preoperative patient-reported outcomes (PROMs). The exclusion criteria were osteoarthritis or “kissing lesions” at the time of surgery. Demographic data, later knee surgery, and PROMs were collected with use of a questionnaire. A Cox regression model was used to adjust for and investigate the impact of risk factors, and Kaplan-Meier analysis was performed to estimate cumulative risk. The risk of knee arthroplasty in the present cohort was compared with that in the age-matched general Norwegian population. Results: Of the 516 patients who were eligible, 322 patients (328 knees) consented to participate. The mean age at the time of the index procedure was 36.8 years, and the mean duration of follow-up was 19.8 years. The 20-year cumulative risk of knee arthroplasty in the cartilage cohort was 19.1% (95% CI, 14.6% to 23.6%). Variables that had an impact on the risk of knee arthroplasty included an ICRS grade of 3 to 4 (hazard ratio [HR], 3.1; 95% CI, 1.1 to 8.7), an age of ≥40 years at time of cartilage surgery (HR, 3.7; 95% CI, 1.8 to 7.7), a BMI of 25 to 29 kg/m2 (HR, 3.9; 95% CI, 1.7 to 9.0), a BMI of ≥30 kg/m2 (HR, 5.9; 95% CI, 2.4 to 14.3) at the time of follow-up, autologous chondrocyte implantation (ACI) at the time of the index procedure (HR, 3.4; 95% CI, 1.0 to 11.4), >1 focal cartilage lesion (HR, 2.1; 95% CI, 1.1 to 3.7), and a high preoperative visual analog scale (VAS) score for pain at the time of the index procedure (HR, 1.1; 95% CI, 1.0 to 1.1). The risk ratio of later knee arthroplasty in the cartilage cohort as compared with the age-matched general Norwegian population was 415.7 (95% CI, 168.8 to 1,023.5) in the 30 to 39-year age group. Conclusions: In the present study, we found that the 20-year cumulative risk of knee arthroplasty after a focal cartilage lesion in the knee was 19%. Deep lesions, higher age at the time of cartilage surgery, high BMI at the time of follow-up, ACI, and >1 cartilage lesion were associated with a higher risk of knee arthroplasty. Level of Evidence: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.
Current sampling and sequencing biases of Lassa mammarenavirus limit inference from phylogeography and molecular epidemiology in Lassa fever endemic regions

Lassa fever (LF) is a potentially lethal viral haemorrhagic infection of humans caused by Lassa mammarenavirus (LASV). It is an important endemic zoonotic disease in West Africa with growing evidence for increasing frequency and sizes of outbreaks. Phylogeographic and molecular epidemiology methods have projected expansion of the Lassa fever endemic zone in the context of future global change. The Natal multimammate mouse (Mastomys natalensis) is the predominant LASV reservoir, with few studies investigating the role of other animal species. To explore host sequencing biases, all LASV nucleotide sequences and associated metadata available on GenBank (n = 2,298) were retrieved. Most data originated from Nigeria (54%), Guinea (20%) and Sierra Leone (14%). Data from non-human hosts (n = 703) were limited and only 69 sequences encompassed complete genes. We found a strong positive correlation between the number of confirmed human cases and sequences at the country level (r = 0.93 (95% Confidence Interval = 0.71 - 0.98), p < 0.001) but no correlation exists between confirmed cases and the number of available rodent sequences (r = -0.019 (95% C.I. -0.71 - 0.69), p = 0.96). Spatial modelling of sequencing effort highlighted current biases in locations of available sequences, with increased effort observed in Southern Guinea and Southern Nigeria. Phylogenetic analyses showed geographic clustering of LASV lineages, suggestive of isolated events of human-to-rodent transmission and the emergence of currently circulating strains of LASV from the year 1498 in Nigeria. Overall, the current study highlights significant geographic limitations in LASV surveillance, particularly, in non-human hosts. Further investigation of the non-human reservoir of LASV, alongside expanded surveillance, are required for precise characterisation of the emergence and dispersal of LASV. Accurate surveillance of LASV circulation in non-human hosts is vital to guide early detection and initiation of public health interventions for future Lassa fever outbreaks.
