Sorption-Enhanced Water-Gas Shift Reaction for Synthesis Gas Production from Pure CO: Investigation of Sorption Parameters and Reactor Configurations

A sorption-enhanced water-gas shift (SEWGS) system providing CO2-free synthesis gas (CO + H2) for jet fuel production from pure CO was studied. The water-gas shift (WGS) reaction was catalyzed by a commercial Cu/ZnO/Al2O3 catalyst and carried out with in-situ CO2 removal on a 20 wt% potassium-promoted hydrotalcite-derived sorbent. Catalyst activity was investigated in a fixed bed tubular reactor. Different sorbent materials and treatments were characterized by CO2 chemisorption among other analysis methods to choose a suitable sorbent. Cyclic breakthrough tests in an isothermal packed bed microchannel reactor (PBMR) were performed at significantly lower modified residence times than those reported in literature. A parameter study gave an insight into the effect of pressure, adsorption feed composition, desorption conditions, as well as reactor configuration on breakthrough delay and adsorbed amount of CO2. Special attention was paid to the steam content. The significance of water during adsorption as well as desorption confirmed the existence of different adsorption sites. Various reactor packing concepts showed that the interaction of relatively fast reaction and relatively slow adsorption kinetics plays a key role in the SEWGS process design at low residence time conditions.
Effect of Ni doping on structural, optical and photocatalytic properties of Zn1-XNiXO nanoparticles prepared by different pH conditions

Zn 1-X Ni X O (x = 0.00, 0.02, 0.04 & 0.06 mol %) nanoparticles were prepared by simple co-precipitation method. The influences of Ni doping on structure, morphology, optical and photocatalytic properties were investigated by means of X-ray diffraction, scanning electron microscopy, UV–Vis spectrophotometer and photochemical reaction method. The obtained result shows that the prepared ZnO nanocrystals were hexagonal wurtzite structure and the average crystallite size decreases with increase of Ni doping. The increase of visible light absorption and increase of band gap were found with the increase of Ni doping concentration, which enable the sample harvest more photons to excite the electron from valence band. The photocatalytic properties of Ni doped ZnO nanocrystals shows enhanced activity that the pure ZnO nanocrystals. The photocatalytic activities were not significantly affected by the particle size and 0.04% Ni doped ZnO nanocrystals shows best catalytic activity than the other catalysts.
The Relationship between Supply Chain Management Practices and Supply Chain Performance in Saudi Arabian Firms

The purpose of this study was to investigate the relationship between supply chain management practices (SCMPs) and supply chain performance (SC performance) within different industries in the Kingdom of Saudi Arabia. An empirical study was conducted on a sample of 196 firms; information was collected from the supply chain managers and those in top management in different industries in the Kingdom of Saudi Arabia. In addition to a series of interviews conducted with managers of the supply chains, a theoretical model was developed depicting the relationship between SCMPs and supply chain performance (SC performance). This model was also tested using multiple regression analysis. The research suggests that SCMPs, including supply chain planning (SC planning), level of information sharing (IS), customer relationship management (CRM), and supplier relationship management (SRM) are all positively related to SC performance. Additionally, SC performance is positively related to FFP. The research employed perceptual performance measures to gauge return on investment, revenue, and sales. Future studies could use actual numbers to better quantify the benefits within this context.
PARENTS’ INVOLVEMENT IN SEXUAL AND REPRODUCTIVE HEALTH EDUCATION FOR CHILDREN: A SCOPING REVIEW

Background: Parents play important role for educationg children about sexual and reproductive health. Sexual and reproductive health education is very important to be provided for children in early age, so that they could protect themselves from sexual violence. However, the information about sexual and reproductive health should be taught by parents so that children do not misstep in their lives. Objective: to review the evidence of parenting involvement in adolescent sexual and reproductive health education. Methods: The method of scoping reviews have adopted the framework of Arksey and O'Malley (2005), the steps of framework are (1) The identification of scoping review questions, (2) The identification of relevant articles, (3) The selection of articles, (4) Data Charting , (5) Maping, collating and summarizing. The writer searches for articles in 3 databases and selects the original article for review. The article theme focuses on the parents involvement in sexual and reproductive health education against children in developing countries that conducted in 2009-2019. Findings: Out of the 8 selected articles. Five themes of scoping review are the factors that influence parent and child communication, such as age, gender, education, social, economic, generation and relationship of family gaps. The obstacle of providing reproductive health education and sexual in children due to parents are ashamed, uncomfortable , lack of knowledge , and the influence of culture and norms. HIV/AIDS is a topic that is often discussed by parents. Knowing about sex education is important for children, while parents and teachers are sources of this information. In order to teach sexual and reproductive health education well, parents need good communication and improve their knowledge. Conclusion: In order to provide sexual and reproductive health education, there are several factors and barriers that affect the communication of parents and children. Parents only discuss sexual and reproductive health issues generally. They also teach their children about the dangers of premarital sex.
Perfectionistic concerns cognitions predict burnout in college athletes: a three-month longitudinal study

ABSTRACT The majority of research examining the relationship between perfectionism and athlete burnout has focused on trait perfectionism, while overlooking the importance of the cognitive elements of perfectionism. Perfectionistic cognitions represent an influential cognitive bias driving perfectionistic behaviour. Although perfectionistic cognitions have been shown to correlate with burnout symptoms in athletes, this body of work is very limited and does not include college athletes. In addition, it is currently unclear whether perfectionistic cognitions also predict changes in athlete burnout over time. To address these issues, we conducted a two-wave, three-month longitudinal study and measured perfectionistic cognitions and burnout in a sample of 170 college athletes both at the start and end of a competitive season. In doing so, we also sought to empirically test the different models of perfectionistic cognitions that have been proposed (original, short, and multidimensional). Using cross-lagged panel models, we found that perfectionistic concerns cognitions predicted increases in burnout. The findings provide initial evidence that perfectionistic cognitions predict changes in athlete burnout over time in college athletes. Consequently, the findings have important implications for our understanding of both athlete burnout and perfectionistic cognitions.
A STUDY OF OUTCOME OF PATIENTS WITH PRETERM PREMATURE RUPTURE OF MEMBRANES IN A TERTIARY CARE HOSPITAL

Background: Premature membrane rupture (PROM) is associated with substantial maternal prenatal morbidity and mortality. The maternal and foetal outcomes in PROM are crucial in Ethiopia, where maternal mortality is still high, to reduce maternal and child mortality as well as to improve care and the avoidance of problems. Aim & Objective: The purpose of the study was to examine maternal and neonatal outcomes in patients who underwent preterm premature membrane rupture as well as to find out how these patients fared during labour. To investigate the mortality and morbidity rates for both mothers and newborns related to preterm premature membrane rupture. Materials and Methods: From February 2021 to July 2021, this observational study was carried out at an obstetrics ward of a tertiary care facility. Result: In both groups, there was evidence of maternal morbidity in terms of PPH, puerperal pyrexia, and wound infection. There was a maternal morbidity of 20.93% in Group I and a morbidity of 41.18% in Group II. The p value was 0.856, which is not significant. In terms of RDS, Sepsis, Hyperbilirubinemia, IVH, Birth Asphyxia, and HIE, there was neonatal morbidity. Neonatal morbidity was 14% in Group I and 41.2% in Group II. Groups I and II both had a 7% and a 23.5% neonatal mortality rate, respectively. The p value is 0.762, which is not significant. Conclusion: Our study's goal was to examine maternal and perinatal morbidity as the duration between PPROM and birth increased. With increased PPROM hours, no statistically significant change was found.
Research on the lean and swept optimization of a single stage axial compressor

Compressor design is always a prevalent research issue as nowadays the compressor demands higher performance. Designing afresh a new compressor of higher aerodynamic performance will cost a tremendous amount of time and expense. Consequently, the wiser method of acquiring a higher performance compressor is to optimize a current compressor, discussed in this paper. First, a detailed numerical simulation of al compressor is done. A parametric rotor model is created and the variations of lean and swept parameters are limited. Then, an optimization calculation is carried out based on the combination of an artificial neural network and a genetic algorithm. The optimization iteration is started at three specified working points – a choke point, a design point and a near stall point – to acquire a comprehensive improved solution. A novel penalty function considering both pressure ratio and efficiency is constructed to find the optimal model. Finally, a detailed review is made of the original and the optimized compressor. The computational results show that the isentropic efficiency is successfully increased and the stall margin is remarkably improved. Ultimately, a detailed vortex structure analysis with increasing outlet pressure is discussed. This helps the performance increment mechanism to be understood further.
Revisiting the measurement of financial inclusion of rural smallholder farmers in Nigeria

PurposeThis study aims to develop and apply a multidimensional measure of financial inclusion (FI) to address measurement issues and determine the level of FI of rural smallholder farmers and the contribution of domain indicators to the level of FI in Nigeria.Design/methodology/approachThe paper adapts the Alkire–Foster method to develop a multidimensional FI index (MFII). A stratified two-stage sampling procedure is used to select 2,300 rural respondents from the 2016 Consultative Group to Assist the Poor (CGAP) Smallholder Household Survey.FindingsResults indicate that 78% of rural smallholder farmers in Nigeria are financially excluded. In addition, owning a formal account is significantly different (p &lt; 0.00) from being financially adequate. The financial capability domain contributes the least (29.66%) to the multidimensional FI (MFI) of rural smallholder farmers relative to financial participation and financial well-being. Financial literacy, consumer protection, overcoming barriers such as high transaction costs and financial planning indicators contribute the least to FI relative to formal access.Practical implicationsResults of the study lead to policy recommendations for increasing the FI of rural smallholder farmers in Nigeria, which may be applicable to other countries.Social implicationsAchieving sustainable FI requires that interventions increase the FI of rural smallholder farmers by strengthening financial capability, participation and well-being and not only focus on formal account owners.Originality/valueThe study provides a new methodological and empirical contribution to the FI literature on rural smallholder farmers.
The Effect of Visualization, Relaxation, and Self-efficacy on the Performance of Men Speed World Record Athletes Category

Background: The speed world record (WR) performance is an achievement made by athletes in the competitive rock-climbing category, where the athlete must complete the climbing route on a standard artificial climbing wall with a height of 15 m in the shortest possible time. Purpose: This study aims to determine: (1) the effect of visualization and relaxation training on athlete's performance; (2) the effect of self-efficacy on athlete's performance, and (3) the interaction between exercise (visualization, relaxation) and self-efficacy on the performance of rock-climbing athletes in the speed world record category. Design/methodology/approach: This research is experimental research with a true experimental design modified with a factorial design (2x2). The population in this study was all junior and youth WR speed rock climbing athletes, aged between 15-20 years in Yogyakarta and Central Java. A sample of 20 men athletes was taken with the Slovin Formula and ordinal pairing technique. The data were collected using the General Self-efficacy Scale (GSE) to measure self-efficacy and motion climb to measure the performance of rock-climbing athletes with WR speed. A Two-Way ANOVA test was used with the following analysis prerequisites: normality test and homogeneity test. The results of this study showed that: (1) Visualization is better than relaxation; (2) Athletes who have high self-efficacy have better performance than athletes who have low self-efficacy; and (3) There is a significant interaction (p<0.05) between exercise (visualization and relaxation) and self-efficacy (high and low) on the performance of rock climbing athletes in the WR speed category. Conclusion: The highest performance is obtained with visualization exercises with high self-efficacy; followed by relaxation with high self-efficacy; and visualization exercises with low self-efficacy.
Central Equatorial Pacific Cooling During the Last Glacial Maximum

Establishing tropical sea surface temperature (SST) during the Last Glacial Maximum (LGM) is important for constraining equilibrium climate sensitivity to radiative forcing. Until now, there has been little data from the central equatorial Pacific in global compilations, with foraminiferal assemblage‐based estimates suggesting the region was within 1°C of modern temperatures during the LGM. This is in stark contrast to multi‐proxy evidence from the eastern and western Pacific and model simulations which support larger cooling. Here we present the first estimates of glacial SST in the central equatorial Pacific from Mg/Ca in Globigerinoides ruber. Our results show that the central Pacific cooled by about 2.0°C during the LGM, in contrast with previous global compilations but in agreement with models. Our data support a larger magnitude of tropical LGM cooling, and thus a larger equilibrium climate sensitivity, than previous studies which relied on foraminiferal assemblages in the central tropical Pacific.
Bioaccessibility of trace elements and chromium speciation in commonly consumed cereals and pulses

ABSTRACT Copper, manganese, and chromium content and their bioaccessibility were determined in commonly consumed cereals and pulses. Copper, manganese, and chromium concentration of these grains ranged from 0.19 to 1.22, 0.46 to 8.12, and 0.02 to 0.11 mg/100 g, respectively. Bioaccessibility of these minerals from the grains ranged from 6.6 to 32.5% (copper), 15.5 to 43.5% (manganese), and 2.66 to 36.4% (chromium). In terms of bioaccessibility of these minerals, pulses provided more than cereals. Speciation analysis of chromium by selective alkaline method demonstrated the presence of the toxic hexavalent chromium in lower concentration than trivalent form.
Sexual Dimorphism in the Functional Development of the Cochlear Amplifier in Humans

Objectives: Otoacoustic emissions, a byproduct of active cochlear mechanisms, exhibit a higher magnitude in females than in males. The relatively higher levels of androgen exposure in the male fetus are thought to cause this difference. Postnatally, the onset of puberty is also associated with the androgen surge in males. In this study, we investigated sexual dimorphism in age-related changes in stimulus-frequency otoacoustic emissions for children. Design: In a retrospective design, stimulus-frequency otoacoustic emissions were analyzed from a cross-sectional sample of 170 normal-hearing children (4 to 12 years) and 67 young adults. Wideband acoustic immittance and efferent inhibition measures were analyzed to determine the extent to which middle ear transmission and efferent inhibition can account for potential sex differences in stimulus-frequency otoacoustic emissions. Results: Male children showed a significant reduction in otoacoustic emission magnitudes with age, whereas female children did not show any such changes. Females showed higher stimulus-frequency otoacoustic emission magnitudes compared with males. However, the effect size of sex differences in young adults was larger compared with children. Unlike the otoacoustic emission magnitude, the noise floor did not show sexual dimorphism; however, it decreased with age. Neither the wideband absorbance nor efferent inhibition could account for the sex differences in stimulus-frequency otoacoustic emissions. Conclusions: The cochlear-amplifier function remains robust in female children but diminishes in male children between 4 and 12 years of age. We carefully eliminated lifestyle, middle ear, and efferent factors to conclude that the androgen surge associated with puberty likely caused the observed masculinization of stimulus-frequency otoacoustic emissions in male children. These findings have significant theoretical consequences. The cochlea is considered mature at birth; however, the present findings highlight that functional cochlear maturation, as revealed by otoacoustic emissions, can be postnatally influenced by endogenous hormonal factors, at least in male children. Overall, work reported here demonstrates sexual dimorphism in the functional cochlear maturational processes during childhood.
THE DESCRIPTION OF KNOWLEDGE, PERCEPTION, ROLE, ROLE IMPLEMENTATION, EMOTIONAL CONNECTION IN PSYCHOSEXUAL DEVELOPMENT OF CHILDREN AGED 3-5 YEARS IN NEW NORMAL PERIOD AT THE SUBURBAN OF SURABAYA

The number of pornography and cybercrime among Indonesian children reaches 4448 cases – children as a perpetrator and victim. Meanwhile, Indonesian children experience 183 cases of rape and sexual abuse, 54 cases of sodomy or pedophilia – children as a perpetrator, 42 cases of sodomy or pedophilia – children as a victim, and 44 cases of abortion. Preliminary study on March 2020 in West Surabaya showed that 6 in 10 children aged 3-5 years faced sexual abuse or harassment and rape by their closest circle. The research aims are to describe the level of knowledge, perception, role implementation, emotional connection between father and child in the accompaniment of psychosexual development of children. This paper combined quantitative and qualitative methodologies with a phenomenological approach. Respondents were father compatible with inclusion criteria – was determined by researchers. This study used total sampling – 112 fathers lived in West Surabaya. The research instruments were questionnaire and observation sheet. Data analysis utilized percentage analysis, data reduction, and data triangulation. Result: There were 64.5% low level of knowledge, 70.5% negative perception, 63.4% father absence in assisting psychosexual development of children, and 69.6% absence of emotional connection. Conclusion: The father’s role in assisting the psychosexual development of children aged 3-5 years can decrease the number of psychosexual disorders in adulthood. Keywords: knowledge, perception, role, role implementation, father, child’s psychosexual
Expression of B Locus Beta 2 (BLB2) Gene at Cytolytic and Latent Immune Response Stages of Immunocompetence in Nigerian Indigenous Chickens

An economically-important trait in poultry for which gene identification continues to be a challenge is immune response. The objective of the study is to quantitate the expression of major histocompatibility complex (MHC) class II BLB2 gene at cytolytic and latent immune response stages in Nigerian indigenous chickens. A total of 108 Nigerian indigenous chickens (NIC) were sourced across the South-western states in Nigeria. The birds were inoculated with sheep red blood cells (SRBC), after which blood samples were obtained (5 days post-inoculation) and antibody haemagglutination test was carried out to place the birds into groups of high and low antibody titre levels. The categorisation of the birds resulted in six groups of normal feather high, normal feather low, naked neck high, naked neck low, frizzle feather high and frizzle feather low antibody groups. A total of 48 chicks were selected from the progeny for gene expression studies. Surgical excision of thymus and spleen was carried out for the detection of cytolytic and latent responses of the birds. β-actin was used as the endogenous control and the critical threshold method (2–ΔΔCт) was carried out for the determination of fold change. The fold change of spleen tissue expression at cytolytic immune response of the birds was 30,362.44 compared to latent response 294.07; and the fold change of thymus expression at cytolytic immune response of the birds was 51.98 compared to latent response 5.24. At both cytolytic and latent stages of immune response to SRBC antigen, BLB2 expression in the spleen was comparatively higher than in the thymus and the height of transcriptional activity was associated with the cytolytic stage. The birds of high titre at both the cytolytic and the latent responses had higher mRNA expression. This study concluded that BLB2 gene expression in the Nigerian indigenous chicken was induced at the cytolytic stage and repressed at the latent stage. During avian infections, the category of high immune response birds would perform better than the low immune response counterpart; and the protective response that BLB2 gene will be repressed from one time point to the other.
What You See is What You G(u)e(s)t: How Profile Photos and Profile Information Drive Providers’ Expectations of Social Reward in Co-usage Sharing

ABSTRACT Co-usage sharing involves social interactions between providers and consumers. Previous research established that individuals’ motivation to engage in such transactions are not only driven by economic factors but also by expectations about the social reward that can be gained from them. This research develops a theoretical model to understand providers’ expectations of social reward and considers how they draw on the consumer’s user representation (profile photo and information) being the only cues available to them.
