Immobilization of tyrosinase on polyacrylonitrile beads: biodegradation of phenol from aqueous solution and the relevant cytotoxicity assessment

An economical and stabilized immobilized-enzyme method was developed for the removal of phenol in wastewater. Tyrosinase was immobilized on the PAN-based beads with glutaraldehyde as was confirmed successfully by a series of characterizations involving Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS). The biodegradation of phenol was investigated by using the immobilized beads and compared to free tyrosinase. The optimum pH and temperature were determined to be 7.0 and 40 °C, respectively. Experiments showed that the immobilized tyrosinase was much more stable than the free tyrosinase in storage and that the immobilized tyrosinase could even retain about 78% of its original activity after repeated use 6 times in a batch system. Furthermore, the comparative in vitro cytotoxicity of phenol/treated solutions were evaluated in LO2 and HepG2 cells by using the CCK-8 assay for cell viability along with flow cytometry detection for apoptosis. The results showed that the toxicity of the phenol solutions only exerted toxicity on cells in a certain concentration range (>0.5 mM for LO2 and HepG2 cells) and that the toxicity of the phenol solutions was greatly decreased after treatment with the tyrosinase-immobilized beads. Thereby, the results confirm that we have established a suitable strategy with promising application to remove phenol economically and efficiently, which could even lower the toxicity of phenol at the cellular level.
PRICE-MATCHING COMPETITION IN THE PRESENCE OF STRATEGIC CUSTOMERS

Competition between retailers leads to an increase in the total inventory on the market while strategic customer behavior works in the opposite direction. Price matching (PM) alters the balance between these forces by working in the same direction as strategic customers and serves as a signal that dramatically changes the equilibrium. We show that PM deserves the close attention of all market participants because it can not only mitigate the loss from strategic customer behavior but may even lead to gains from increases in the level of this behavior under competition. At the same time, combined effects of PM and strategic behavior may cause the equilibrium retailer profit with PM to be less than the worst equilibrium profit without PM. Manufacturer never benefits from PM except for branded products when the sales at reduced prices are undesirable. On the other hand, policymakers may encourage PM since it can improve the aggregate welfare.
Single-ion Hydration and Ion Association in Aqueous Solutions

The research has focused on three projects: 1) fundamental thermodynamics aspects of ion hydration; 2) the driving forces for ion pair association; 3) a phase diagram calculation of the binary system consisting of water and 1-butanol using free energy methods developed in 1) and 2). First, the single ion hydration free energy is computed by quasi-chemical theory. An issue is that a Gaussian model fails to estimate the anion long-ranged contribution at intermediate cavity sizes; this issue is represented and addressed by the midpoint rule. It is found that the work of growing a cavity to a 6.15 Å size is equal to minus the ions’ bulk hydration free energy, suggesting that a consistent shift of ± 11.6 kcal/mol (across the alkali halide series) arises due to the net potential at the center of this cavity. Second, the local molecular field theory is employed to partition the potential of mean force of ion pairs. The association behavior of ion pairs is shown to be in line with the law of matching water a nity, and the local electrostatic contribution is seen to provide ion specificity. Correlation of the local electrostatic contribution with the coordination number is presented. Third, a calculation method for a binary mixture phase diagram is developed in the context of the potential distribution theorem. The quasi-chemical theory is used to estimate the hydration free energy of probe water molecules. Through the Gibbs-Duhem equation, the activity coe cients of both water and 1-butanol can be obtained. The subsequent optimization of an empirical excess Gibbs model produces i the Gibbs energy profile over all the concentrations, and its double-tangent points locate the phase boundaries.
Vapor Pressure and Boiling Point

As one of the important chemical-engineering properties vapor pressure plays significant role for fire and explosion prevention, gas separation, design and optimization of the processes. This chapter discusses several vapor pressure equations, such as Riedel's equation, Velasco equation, Wagner equation, and Cox's equation. Most vapor pressure of chemical substances have been reported between 5 and 100 kPa. Generally, the methods for the determination of vapor pressure are divided into four groups, the static methods, dynamic methods, effusion methods, and equilibration methods. The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid. The normal boiling point of a liquid is when the vapor pressure of the liquid equals to one atmosphere. There is currently a lot of experimental data for vapor pressures of smaller molecules but data is scarce or of low quality for larger and more complex molecules of low volatility.

166 G2019-010 Neutrophil Gelatinase-Associated Lipocalin_Layout 1

OBJECTIVE: To evaluate the serum neutrophil gelatinase-associated lipocalin levels in pregnant women with and without preeclampsia, early-onset preeclampsia and late-onset preeclampsia, preeclampsia with and without severe features, and investigate the correlation with the neonatal outcomes. STUDY DESIGN: A total of 79 pregnant women, 27 with uncomplicated pregnancies, 30 with early-onset preeclampsia, and 22 with late-onset preeclampsia were evaluated in a cross-sectional study. Neutrophil gelatinase-associated lipocalin was measured with a colorimetric Sandwich-ELISA method. Age; body mass index; systolic and diastolic blood pressure; umbilical-artery Doppler results; serum urea, bilirubin, uric acid, AST, ALT; 24-hour protein test; birth-weight; and Apgar-scores were recorded. RESULTS: Serum neutrophil gelatinase-associated lipocalin levels were significantly higher in women with preeclampsia compared to those without preeclampsia (p<0.001); in women with early-onset preeclampsia compared to those with late-onset preeclampsia (p<0.001); and in women with late-onset preeclampsia compared to those without preeclampsia (p=0.028). Mean serum neutrophil gelatinase-associated lipocalin levels were comparable in women with preeclampsia with and without severe features (p=0.076). The correlation analysis showed that neutrophil gelatinase-associated lipocalin was not affected by age or body mass index. Neutrophil gelatinase-associated lipocalin had a positive correlation with systolic and diastolic blood pressure and the umbilical-artery PI and RI. Serum neutrophil gelatinase-associated lipocalin had a positive correlation with serum urea (r=0.416, p=0.031) however had no significant correlation with birth-weight, Apgar-scores, uric acid and amount of proteinuria in women with preeclampsia. CONCLUSION: Serum neutrophil gelatinase-associated lipocalin levels were significantly higher in women with preeclampsia compared to those without preeclampsia; in women with early-onset preeclampsia compared to those with late-onset preeclampsia, and in women with late-onset preeclampsia compared to women without preeclampsia. Mean serum neutrophil gelatinase-associated lipocalin levels were comparable in women with preeclampsia with and without severe features.
Control of Intestinal E. coli Infection in Broiler Chicks Using Lactobacillus casei Isolated from Nono

The current study aimed to evaluate whether the probiotic Lactobacillus casei could be effective in controlling chicken intestinal colibacillosis. Avian pathogenic Escherichia coli (E. coli.) and Lactobacillus casei (L. casei) isolates were obtained from nono (a sour milk product produced by Fulani tribe of Nigeria), and were used for the chicken infection and probiotic treatment, respectively. The experimental design was conducted on three-week-old broiler chicks, which were divided into five groups, namely A (healthy control), B (infected without treatment), C (infected and treated with antibiotic), D (infected and treated with L. casei), and E (initially given L. casei before infecting with E. coli). Groups C and D were treated using 15 g/L norfloxacin and 1.5 ml of 1.1x10cfu/ml L. casei, respectively. Group E was given the oral infusion of 1.5 ml of 1.1 × 10 cfu/ml L. casei before infection with 1.5 ml of 1.3 × 10 cfu/ml avian pathogenic E. coli. Weight, hematological parameters, liver function, and fecal E. coli counts of the chicks were monitored and used to evaluate the level of protection elicited by the probiotic organism. There was weight gain in chicken groups, except for group B. There was a significant difference in the sodium, chlorine, and bicarbonate levels amongst the groups. The hematological profile revealed a significant difference in the hemoglobin, white blood cells, lymphocyte, and neutrophil counts of the chicken groups. Assessment of liver enzymes showed no significant difference amongst the chick groups except in group B. Similar results were obtained for the urea, creatinine, and C-reactive protein levels. The microbial tests revealed a decrease in the total E. coli count for groups C, D, and E. The results of the current study indicated that L. casei could be used as a probiotic in the control of chicken colibacillosis.
Psycho-Demographic Factors Predisposing School Adjustment Among The Adolescents in Osun State, Nigeria

The study examines the Psycho-demographic factors predisposing school adjustment among In-school adolescents in Osun state, Nigeria. The study adopted a descriptive design of correlational type. A Sample of three hundred In-school adolescents were selected using a multistage sampling technique. Data collected were analyzed using Pearson Product Moment Correlation, T-test and Multiple regression analysis. Results indicated School adjustment positively correlated with peer pressure (r= .461, p< 0.05), emotional instability (r = .665, p<0.05) while school adjustment is negatively correlated with gender (r= -.332, p<0.05). All the independent variables jointly accounted for 48.5% variance in predicting school adjustment among In-school adolescents. Two out of three predictors (emotional stability and gender) are potent predictors of school adjustment. The most potent factor was emotional stability (β = .591, t= 11.611, P<0.05), followed by gender (β = -.205, t= -4.757, P<0.05 except peer pressure (β = .062, t= 1.198, P>0.05) which is not a potent predictor of school adjustment. This implies that, an increased influence of emotional stability will increase school adjustment by 59.1% and gender will increase school adjustment by 20.5%. Also, the T-test analysis reveal a significant difference in the school adjustment of male and female; t (298) = 6.081, p<0.05.

Evaluation of the psychometric properties of the Treatment Self-Regulation Questionnaire for chronic diseases. Revista de Enfermagem Referência, 5(2), e19069. doi:10.12707/RIV19069 Abstract Background: The promotion of the management of the therapeutic regimen in people with chronic disease implies reliable and valid measures to assess motivation for treatment. Objective: To assess the psychometric properties of the Portuguese version of the Self-Regulation Questionnaire (SRQ) of the medication treatment in a sample of people with chronic disease. Methodology: A methodological study was conducted using the Confirmatory Factor Analysis (CFA). The sample was comprised of 189 people with chronic disease. Results: A three-factor solution of the SRQ showed poor fit to the model, thus a four-factor solution was suggested. The convergent validity was confirmed by associations between autonomous motivation, perceived competence and perception of a therapeutic environment that promotes autonomy, and adherence to medication. The reliability analysis showed satisfactory internal consistency values ranging between 0.56 and 0.90. Conclusion: The instrument shows good reliability and validity to assess self-regulation of the treatment regimen in people with chronic disease.
MALAYSIAN ONLINE JOURNAL OF EDUCATIONAL MANAGEMENT (MOJEM)

It is necessary that educational institutions are administered by leaders with visions who can be flexible while maintaining the institutions’ missions. Instructional leadership will enable the leaders to manage effectively and to persuade teamwork to be fully engaged in dynamic educational contexts. The purpose of this study is to explore the effectiveness of instructional leadership as an independent variable to instructors’ behavior. This relates to employees’ loyalty to their leaders and institutions through the relationship quality as a mediator variable which is considered as a direct effect from instructional leadership. The research’s respondents were instructors who worked under the dual system of private vocational education institution in Thailand and the sample data was collected from 396 instructors. The result showed that almost variables has a direct impact to each other except trust in the relationship quality group. This variable has no effect on job satisfaction and institution loyalty (p < 0.05). The model explained that 60.9 percent of leader loyalty and 59.7 percent of institution loyalty were variation of instructional leadership. The finding clearly reveal the instructional leadership helps to estimate what can contribute to the relationship quality and the loyalty in educational institution. The study recommends that the board of management with instructional leadership should examine the personnel’s needs to maximize institutional personnel in a more professionally manner.
Egg Production, Fertility, Hatchability and Luteinizing Hormone Profile of Progesterone Hormone Injected to Arabic Gold Chicken (Gallus turcicus)

The production and reproduction performance of chicken depends on their hormonal status, especially progesterone hormone, which has been known to correlate with egg production. The present study aimed to analyze the effect of progesterone hormone injection on Arabic Gold chickens (Gallus turcicus) regarding egg production and luteinizing hormone concentration in blood plasma. A total number of 60 Arabic Gold chickens aged 26-weeks were divided into three groups based on injected hormone concentration (P0: control; P1: 1 mg/chicken; P2: 2 mg/chicken). The study was conducted using a completely randomized design and the obtained data were analyzed with a descriptive analysis for qualitative data and one-way analysis of variance followed with Duncan’s Multiple Range Test as a post hoc test for the quantitative data. The results presented that progesterone hormone injection had a significant effect on hen day production two and six weeks after injection. The P1 group was able to reach its peak production (82.9%) at week 29, while the P2 group reached its peak at week 26 (78.9%). In addition, it was found that the P2 group produced a soft-shelled egg and double egg yolk. Progesterone injection led to no significant effect on the egg weight, shape index, fertility, embryo viability, hatchability, and chick weight at hatch. The luteinizing hormone concentration was higher in P2 (1.52 ng/ml), compared to P0 (1.36 ng/ml) and P1 (1.34 ng/ml) groups. It was concluded that progesterone hormone injection during the production phase of Arabic Gold chicken had a significant effect on egg production and caused varying egg production peak and luteinizing hormone concentration.
Advanced SiC/Oxide Interface Passivation

To save energy on an electric power grid, the idea of redesigned ‘micro-grids’ has been proposed. Implementation of this concept needs power devices that can operate at higher switching speeds and block voltages of up to 20 kV. Out of SiC and GaN wide band gap semiconductors, the former is more suitable for low- as well as high-voltage ranges. SiC exists in different polytypes 3C-, 4H- and 6H-. 4H-SiC due to its wider band gap, 3.26 eV has higher critical electric field of breakdown (E c ) and electron bulk mobility compared to 6H-SiC. Even with all these benefits 4H-SiC full potential has not yet been realized. This is due to high trap densities (D it ) at the interface. In addition to 4H-polytype, in recent years, there is a reignited interest on cubic silicon carbide (3C-SiC), which can be potentially grown heteroepitaxially on 12″ Si substrates, as it would result in a drastic cost reduction of semiconductor devices compared to the successful but exorbitantly expensive SiC hexagonal polytype technology (4H-SiC). In this chapter, we discuss and summarize all different interface passivation techniques or processes that have led to a vast improvement of these (4H- or 3C-SiC/SiO 2 ) interfaces electrically.
Exports, Imports, and Economic Growth Nexus in Iran: Bounds test approach to Cointegration

This paper examines the long-run relationship between exports, imports and economic growth in Iranian economy using annual data over the period of 1960-2007. As Iran is an oilexporting country, and oil-export boom has a direct impact on the import demand function, and it leads to higher levels of consumption that impact on growth, we emphasize the role of the imports variable in this investigation. Moreover, following recent studies about importance of human capital in endogenous growth models, we extend Feder's model (1982) by entering a proxy for human capital. As Iranian economy has been subject to numerous shocks and regime shifts, we apply Bai and Perron (2003) test to detect any possible endogenous structural breaks. Hence, investigating data properties by concerning structural breaks shows that our variables are not in the same order of integration. This property convince us to use Bounds Test approach to cointegration developed by pesaran et, al. (2001) where it can be applied irrespective of order of integration of the variables. Finally, being sure about existence a long-run relationship between variables, ARDL approach and ECM employed to argue about short-run and long-run coefficient. The results reveal that while there is significant positive relationship between exports and economic growth, the effect of imports is insignificant and also human capital has a negative effect on growth both in short and long run.

Elderly Hip Fracture during Covid-19 Pandemic: What we are Learning

In December 2019 when first cases of Coronavirus 19 Disease (COVID-19) appeared, we couldn’t imagine the spreading capacity neither infectious aggressiveness of this virus. Europe health services have been blocked to control this pandemic state. Orthopaedic departments reduced their activities just for treating the emergent and urgent pathologies such as fractures, infections and tumors. Because of the specific biological conditions of the elderly that suffer a hip fracture, they usually present high rates of complications and mortality after surgery [1]. The objective of this review is to know the impact of this viral infection in patients with hip fracture, as COVID-19 seems to affect the global immune and inflammatory system.
Nanofluid Enhanced Oil Recovery Using Hydrophobically Associative Zwitterionic Polymer-Coated Silica Nanoparticles

Intense interest has been shown in the development of “smart nanofluids” because they can dramatically change their flow properties in complex fluid systems. We introduce a robust and straightforward approach to develop a smart nanofluid system, in which associative silica nanoparticles (ASNPs) were incorporated to regulate their flow properties in rock pores. ASNPs were synthesized by covalently coating a hydrophobically associative hygroscopic zwitterionic poly[2-methacryloyloxyethyl phosphorylcholine (MPC)-co-divinylbenzene (DVB)] shell layer on 20 nm sized silica nanoparticles (NPs) by surface-mediated living radical polymerization. The essence of our approach is to copolymerize DVB, which endows the polymer shell of ASNPs with a weak long-range hydrophobic attraction. This leads to the favorable formation of a wedge film as a result of structural disjoining pressure. This wedge film made the oil adsorbed on the rock surface more dewettable, thus enhancing the efficiency of oil recovery. As a result o.
University of Birmingham Frequencies of board meetings on various topics and corporate governance

This paper examines the relationship between numbers of topic-specific board meetings and quality of corporate governance. The quality of corporate governance is estimated by CEO turnover-performance and compensation-performance sensitivities. Information about topicspecific meetings is collected from the reports of independent directors of Chinese listed firms. We find that more-frequent discussions of growth strategies related to the use of IPO proceeds, investment and acquisitions increase CEO compensation-performance sensitivity. By contrast, more discussions about the nomination of directors and top management are likely to reduce the sensitivities of both CEO turnover and compensation to performance. Our findings shed light on what makes boards efficient, and how board monitoring of assorted decisions modifies the relationship between CEO interests and firm performance.

A Social Media Study on Mental Health Status Transitions Surrounding Psychiatric Hospitalizations

For people diagnosed with a mental illness, psychiatric hospitalization is one step in a long journey, consisting of clinical recovery such as removal of symptoms, and social reintegration involving resuming social roles and responsibilities, overcoming stigma and self-maintenance of the condition. Both clinical recovery and social reintegration need to go hand-in-hand for the overall well-being of individuals. However, research exploring social media for mental health has considered narrower, disjoint conceptualizations of people with mental illness - either as a patient or as a support-seeker. In this paper, we combine medical records with social media data of 254 consented individuals who have experienced a psychiatric hospitalization to address this gap. Adopting a theory-driven, Gaussian Mixture modeling approach, we provide a taxonomy of six heterogeneous behavioral patterns characterizing peoples' mental health status transitions around hospitalizations. Then we present an empirically derived framework, based on feedback from clinical researchers, to understand peoples' trajectories around clinical recovery and social reintegration. Finally, to demonstrate the utility of this taxonomy and the empirical framework, we assess social media signals that are indicative of individuals' reintegration trajectories post-hospitalization. We discuss the implications of combining peoples' clinical and social experiences in mental health care and the opportunities this intersection presents to post-discharge support and technology-based interventions for mental health.
