Performance and kinetic modeling of modified attached-growth anoxic-oxic-anoxic reactor for onsite sanitation system treating septic tank effluent

This paper investigated a combined process of a modified attached-growth anoxic-oxic-anoxic reactor (AG-AOAR) as a sustainable and effective post-treatment system for septic tank effluent was developed. The AG-AOAR was operated by varying hydraulic retention times (HRTs) from 24 to 72 h. The results showed that the AG-AOAR achieved highest removal efficiencies of 84, 66 and 91% of chemical oxygen demand (COD), total nitrogen (TN) and ammonium nitrogen (NH4-N), respectively, under the HRT of 72 h, resulting its effluent meeting the international and national discharge quality standards for non-sewered sanitation system. The Stover-Kincannon model was applicable to describe the kinetic constants of COD, TN, and NH4-N removal in the AG-AOAR (R2 > 0.85). Accordingly, the maximum utilization rates (μmax) were determined to be 41.1, 0.15 and 0.50 g/(L-d) for COD, TN and NH4-N removals, respectively, while the saturation constants (KB) were 57.7, 0.12 and 0.51 g/(L-d), respectively. These constant values could be applied for the design of the AG-AOAR to produce treated effluent meeting desired standards.
Estimates of Genetic Parameters for Economic Traits of Holstein Friesian Dairy Cattle in Tropics: A multi-trait animal model

Background: In any genetic improvement program, multi-trait estimates of genetic parameters and breeding values of economically important traits are essential to facilitate total merit index selection objectives.Method: Data comprising 4,263 lactation records of 1,223 cows calved in the years between 1992 and 2017 were used to estimate genetic parameters and breeding values of lactation milk yield (LMY) and lactation length (LL) and fertility (age at first calving, AFC; calving interval, CI; and days open DO) traits. Preliminary analysis of fixed effects used in the mixed model analysis was tested for their significance using lm package of R software. C(o)variance components and resulting parameters were estimated by fitting single and multi-trait repeatability animal models using BLUPF90 software packages.Results: The heritability estimates of LMY and LL were 0.21±0.04 and 0.13±0.02, respectively. Heritabilities for AFC, CI, and DO were 0.53, 0.12, and 0.14±0.04, respectively. Repeatability estimates of production and fertility traits were low to moderate. The genetic correlation between LMY and LL was high (0.53) whilst, among fertility traits, the estimates were ranged from 0.09±0.03 (between AFC and CI) to 0.99±0.01 (between CI and DO). Genetic correlations of productive traits with fertility traits were ranged from -0.01 to 0.99. The phenotypic correlations between production and fertility traits ranged from 0.06±0.02 for LL and AFC to 0.43±0.02 for LL and DO. The genetic trends for LMY and LL were positive and genetically improved by 15.80 kg year−1 and 0.92 days year−1, respectively. Regarding fertility traits, favorable trends of -0.56 and -0.65 days year-1 were observed for CI and DO, respectively. However, unfavorable trends of 0.04 month year−1 were obtained for AFC.Conclusion: With this small herd size, the study highlighted that a high response to selection for LMY and AFC would be expected in this population. Furthermore, aggregate selection of both production and fertility traits should take into account their antagonistic genetic correlations in future improvement programs.
Youth Experiences of Violence at Home, School, and Street in Disadvantaged Urban Neighborhoods of Islamabad, Pakistan: Troika of Violence

ABSTRACT Youth and Violence have mostly been correlated with either neighborhood, school, or street environment. The current study aims at exploring how the violent experiences of youth at home, school and the street are interconnected, an area of study that has been overlooked in previous studies. Thirty in-depth interviews were conducted with violent youth aged between 14 and 21 years in two disadvantaged urban neighborhoods of Islamabad. The findings show that youth had cyclical experience of violence on three fronts including their homes, schools, and streets in Islamabad. The analysis led us to term these consequential violent experiences among Pakistani youth as the “Troika” of violence. The troika of violence, thus, engages an individual in its vicious cycle, where shared standards of street code become desirable attributes for the youth of disadvantaged neighborhood at home, school, and the street.
Cold spell variability in Europe in relation to the degree of climate continentalism in 1981–2018 period

Seasonal and multiannual variability of the number, duration and severity of cold spells in Europe were analysed in this paper in cold seasons starting with 1981/1982 through 2017/2018. Data were used from seven weather stations characterised by different degrees of climate continentalism. Cold spells did not occur in the oceanic climate of southeastern England. In the Netherlands only a few cold spells were identified in the entire study period lasting 31 or 67 days in total, depending on the method used. The number, duration and severity of cold spells increased toward the east. In the continental climate of the European part of Russia, 163 or 74 cold spells were identified. Their total duration exceeded 1300 days. In Western Europe the potential period when cold spells occurred lasted about 50 days, from the middle of December to the beginning of February. In Eastern Europe the period when cold spells occurred lasted about 140 days, from the beginning of November to the second half of March. The longest and the most severe cold spells were concentrated in four periods: 1984/1985 to 1986/1987, 1993/1994 to 1996/1997, 2001/2002 to 2005/2006 and 2009/2010 to 2011/2012. Statistically significant trends in the number, duration and severity of cold spells were not evident for the locations analysed over the period from 1981 to present.
Auditory Alerts and Safety with Simulated Bicycles and Motor Vehicles

Bicycling has become an increasingly popular and environmentally friendly active transportation modality for many commuters across the nation. Consequently, as ridership increases so does the rate of bicycle–motor vehicle crashes, many of which are caused by reduced bicycle visibility and driver inattention. Therefore, one effective solution to improve bicyclist safety may be through the use of an audible bicycle alarm system to alert both the driver and the rider. A study was conducted to determine whether a unique auditory alert would be effective at reducing crash rates and whether a localized alert (i.e., an alert presented from the driver’s perspective) would improve the driver’s responsiveness in avoiding a potential collision. A driving simulator study tested car horn sounds, an experimental bike alert, and no auditory alert in different potential collision scenarios to measure collision rates and other collision avoidance metrics. Findings indicated that the experimental bike alert contributed to fewer relative crashes than the horn sound and no sound on bicycles, motor vehicles were struck more frequently than bicycles, collisions were more likely to occur from the front than the sides, and collisions were more likely for drivers going straight than when making turns. Taken together, the findings suggest that an alarm designed to be specifically compatible with bicycles is more effective than auditory alerts from other sources.
To what extent did independent directors help firms’ recovery during the COVID-19 pandemic? Evidence from China

ABSTRACT To what extent did independent directors help firms’ recovery during the COVID-19 pandemic? In this paper, we answer this question by investigating whether independent directors contribute to Chinese listed firms’ operation income growth during the first and second quarters of the year 2020. By employing a triple difference-in-differences (DDD) estimation strategy, we show that firms located in more pandemic-affected regions experienced a more pronounced operating recovery if they receive more independent directors’ opinions and have fewer female and busy directors. The possible reason is that those female and busy directors were likely to be distracted during the pandemic outbreak. We also provide evidence that firms paying higher remunerations to independent directors tend to recover quicker. Moreover, independent directors’ age and education level positively contribute to firms’ recovery. Our work is among the first to study independent directors’ role in shaping firms’ operation performance under the COVID-19.
High-Performance Nanocatalyst for Adsorptive and Photo-Assisted Fenton-Like Degradation of Phenol: Modeling Using Artificial Neural Networks

High-performance activated carbon-zinc oxide (Ac–ZnO) nanocatalyst was fabricated via the microwave-assisted technique. Ac–ZnO was characterized and the results indicated that Ac–ZnO is stable, had a band gap of 3.26 eV and a surface area of 603.5 m2g−1, and exhibited excellent adsorptive and degrading potentials. About 93% phenol was adsorbed within 550 min of reaction by Ac–ZnO. Impressively, a complete degradation was achieved in 90 min via a photo-Fenton/Ac–ZnO system under optimum conditions. An artificial neural network (ANN) model was developed and applied to study the relative significance of input variables affecting the degradation of phenol in a photo-Fenton process. The ANN results indicate that increases in both H2O2 and Ac–ZnO dosage enhanced the rate of phenol degradation. The highest rate constant at the optimum conditions was 0.093 min−1 and it was found to be consistent with the ANN-predicted rate constant (0.095 min−1).
The role of self-care and professional quality of life in sustaining a long-lasting career in sport psychology: A qualitative exploration

Abstract In this study, we aimed to explore experienced and senior sport psychology professionals’ (SPPs’) understanding of and experiences with the relationship between their professional quality of life and self-care. Adhering to the philosophical stance characterizing the consensual qualitative research methodology, we conducted a qualitative study using semi-structured interviews. Following criterion-based sampling, we interviewed 10 male and 10 female experienced and senior (M years of practice = 23.9; SD = 8) SPPs from seven countries and four continents who worked in university (n = 10), private practice (n = 7), and governmental (n = 3) settings. We constructed one main domain encompassing seven categories (viz. Inextricably interrelated, Personal relationships, Professional relationships, Role model, Influence of SC on SP-PQL, and Enhancement of professional effectiveness) that highlight quality of life and self-care as inextricably linked and combined to provide a foundation for one’s professional journey. The participants highlighted the importance of concurrently engaging in practices aimed to take care of themselves. They also described their professional experiences to protect and preserve themselves and their ability to guarantee the delivery of ethical and effective care to their clients as well as to their students. These can be interpreted to highlight the key interplay between practitioner holistic well-being, effectiveness, and a meaningful and lasting career in the sport psychology profession. Recommendations for professionals are discussed in terms of implications for professional bodies, supervisors and employees. Lay summary: Sport psychology practitioners (SPPs) are the main agent for their interventions with clients. Twenty SPPs shared their understanding of and experiences with the relationship between their professional quality of life and self-care. The data highlight the interrelated nature of these constructs and their links to effective and ethical practice. Implications for practice Sport psychology professionals may engage in practices devoted to positively enhancing their professional experience to support a long-lasting and effective career. Sport psychology professionals may explore, develop and implement strategies to protect and enable personal flourishing and as a way to enhance their professional career. Sport psychology professionals may benefit by dedicating meaningful time to their own personal and professional development to foster congruent, complementary, and reciprocally nurturing aspects of their lives.
The Role of Identity Prioritization

Social Identity Theory suggests that individuals are motivated to support/oppose policies and politicians that benefit/harm members of their ingroup as a means of protecting their social status. Since the Republican Party’s rhetoric against immigrants in recent decades has often been viewed as an assault upon those of Latinx descent, it is not surprising that strong majorities oppose restrictionist immigration policies and support the Democratic Party. However, the existing literature has overlooked why a sizeable minority of Latinx voters express support for restrictionist immigration policies and the politicians who espouse them. Our analysis of Latinx voters with the 2012 and 2016 American National Election Studies (ANES) demonstrates that the degree to which individuals prioritize their US American identity over their Latinx identity has a significant influence over support for conservative immigration policies and GOP candidates. This relationship emerges above and beyond partisanship, ideology, and other key explanatory factors. Such attitudes likely represent an individual social mobility strategy in which members of a social group attempt to “pass” as a member of a higher-status group. Prioritizing a US American identity, supporting the Republican Party, and expressing hostility toward the interests of undocumented immigrants are a means of distinguishing themselves from a social group that has become increasingly associated with negative stereotypes. In contrast, those who are unwilling or unable to make this transition are likely pursuing a collective social mobility strategy (e.g., linked fate) whereby they attempt to enhance their individual status by elevating that of the entire social group.
Respiratory Consequences of N95 Mask during Covid-19 Pandemic- An Observational Study

Background: Outbreak of novel corona virus has led World Health Organization (WHO) to come up with healthcare guidelines which includes wearing of N95 mask. The aim of this study was to evaluate whether blood oxygen saturation level is affected by wearing of N95 mask for the duration of 4 hours. Materials and Methods: A total of 90 exam going students were included in this study, who were instructed to wear N95 mask. Blood oxygen saturation level (SpO2) was checked both before and after wearing of N95 mask for a period of 4 hours. Results: It was observed that, before wearing N95 mask at 9 am, SpO2 values were 96.64±0.196 while at 1 pm after removing N95 mask, the saturation values were 95.68±0.235 (p=0.000) among all the students. There was a statistically highly significant difference seen for the values between the time intervals (p<0.01) with higher values at 9 am and lesser at 1pm. On comparing the SpO2 levels among males and females, a statistically nonsignificant difference was seen. Thus, reduction in blood oxygen saturation level can be a major parameter to evaluate the respiratory consequences of N95 mask. Conclusion: Various adverse effects of N95 mask were quoted in literature but respiratory consequences due to reduction in blood oxygen saturation level can be harmful. Thus, to avoid such consequences, precautionary measures are advised to be taken. Key words: N95 mask, SpO2, Blood oxygen saturation, COVID-19.
Mucin-1 expression in endometrial tissue of Macaca nemestrina during mid-luteal phase after controlled-ovarian hyperstimulation

Abstract. Sahar N, Birowo P, Kusmardi, Kristianty D, Rahmaningrum K, Miranda AV, Rasyad A, Prasasty VD. 2021. Mucin-1 expression in endometrial tissue of Macaca nemestrina during mid-luteal phase after controlled-ovarian hyperstimulation. Biodiversitas 22: 1927-1933. Endometrial receptivity is one of the factors for successful implantation in pregnancy. Controlled ovarian hyperstimulation (COH) is a required step of in vitro fertilization (IVF), one of the standard procedures to overcome infertility. Exogenous gonadotropin hormones from COH provoke the secretion of estrogen and progesterone from the ovaries in higher amounts. The supraphysiological environment could impact the endometrial receptivity of the implantation process. Mucin-1 (MUC1) can be used as a marker to indicate alterations in the endometrial tissue. Therefore, this study aimed to investigate the alteration of mucin-1 expression in endometrial tissue of Macaca nemestrina after COH protocol. This study used endometrium tissue of M. nemestrina embedded with paraffin as tissue blocks. The subjects were 15 female macaques in reproductive age (8-10 years old) with a history of producing offspring. These macaques were classified into four groups based on the COH protocols, which consist of administering gonadotropin-releasing hormone (GnRH) agonist and recombinant FSH (r-FSH) with dosages of 30 IU, 50 IU, 70 IU (intervention groups), and no r-FSH (control group). The stimulations were administered for 14 days during the mid-luteal phase. Moreover, tissue staining was done by using immunohistochemistry. Mucin-1 expression was analyzed manually for glandular and luminal compartments and automatically for the stromal compartment by Red Green Blue (RGB) measure plugin as a color image from ImageJ software. The expression of mucin-1 was counted semi-quantitatively as H-score. Mucin-1 expression differences in endometrial tissue were assessed by one-way ANOVA with a significant difference found in the glandular part and insignificant results found in luminal and stromal parts. Pearson correlation test was also performed to determine the relationship of steroidal hormones and mucin-1 expression in glandular and luminal compartments. Both correlations were statistically insignificant. However, a positive correlation was found with the glandular compartment and a negative correlation with luminal compartment. As the subject species, M. nemestrina is limited for research utilization in our country, small number of subjects becomes a limitation of this study. Further studies need to be conducted to deepen the understanding of the regulation of mucin-1 expression, particularly by the altered concentrations of steroidal hormones as a consequence of COH.
A COMPASS for Navigating Relationships in Co-Production Processes Involving Vulnerable Populations

ABSTRACT When it comes to engaging vulnerable populations in co-production, power imbalances across stakeholder groups can create methodological challenges. A thoughtful, planned, and responsive approach is needed to prepare vulnerable participants to fully engage in co-production processes. Data from key informant interviews (n = 16) and author reflections on three Experience-based co-design (EBCD) studies involving youth (16–25 years) with mental health issues in Ontario Canada, were analyzed. Four overarching themes and 12 subthemes were identified, and heuristic tools (a relational COMPASS and MAPS directions) were developed to assist researchers in navigating vulnerability, power and relational issues in co-production processes involving vulnerable populations.
Clinical outcome of acute Monteggia fractures in children after open reduction and internal fixation of ulna

Background: Monteggia fracture dislocations are a rare but a complex injury. The fracture of the ulna associated with proximal radioulnar joint dissociation and radio capitellar dislocation. This injury comprises less than 1% of all pediatric forearm fractures and typically affects patients between 4 and 10 years of age. There are many options for treatment of these fractures. The present study was planned to assess the clinical outcome of patients treated with open reduction and internal fixation of ulna with plating.Methods: The study was conducted in department of orthopedics, government medical college and hospital, Jammu from August 2018 to January 2021. 25 patients of Monteggia fractures were managed with open reduction and internal fixation of ulna with plating. Patients were evaluated at follow-up for pain, stability and disturbance of daily and sports activities. Functional outcome was assessed using elbow performance score.Results: Mean age of study participants was 8.2 years and male children predominated our study constituting 17 patients (68%). 14 patients were Bado type 1, four patients were Bado type 2 whereas seven patients were Bado type 3. The outcome was excellent in 18 patients (72%) and no cases of failure were encountered.Conclusions: Stable anatomical fixation by open reduction and internal fixation of ulna fractures with plating, that in turns leads to the stable reduction of radial head, in the management of acute Monteggia fracture dislocations in children has a very good outcome.
Changes in Victorian entrepreneurship in England and Wales 1851-1911: Methodology and business population estimates

Abstract The full population of England and Wales employers and own-account business proprietors is estimated using population censuses 1851–1911. The main contribution of the article is a method of mixed single imputation to overcome the challenge of non-responses to the census 1851–1881. This method is compared with alternatives. Downloads of all data allow replication. The method is used to track trends in proprietor numbers and entrepreneurship rates to reassess the ‘decline of Victorian entrepreneurship’, onset of the ‘U’-shaped trough of the twentieth century, the ‘climacteric’ of 1901, and compositional changes by sector and sex. There is strong sector and gender diversity, with changes in female participation major drivers of overall trends. Proprietor numbers show slow increases of employers, and rapid rise and then decline of own-account, with a turning point after 1901. The methodology and turning point is compared and confirmed against the 1921 census and national and local trade directories.
