Application of Fenton´s Reagent for Acrylic Dyeing Wastewater Decolorization, Organic Matter Reduction and Biodegradability Improvement

Abstract Fenton's reagent oxidation was employed for organic matter and color removal, along with biodegradability improvement, of a synthetic acrylic dyeing wastewater, previously treated by coagulation/flocculation. The initial iron load in the Fenton’s stage varied from the residual soluble iron concentration resulting from the coagulation/ flocculation process (which was 275 mg Fe/L) up to 400 mg/L, by adding increasing amounts of ferrous sulfate. The combination of the two treatments led to overall removals of 99.8, 84.2 and 78.6% for color, dissolved organic carbon (DOC) and chemical oxygen demand (COD), respectively, complying with maximum allowable discharge values. The Fenton process was also directly applied to the effluent. Under the optimum conditions, the color removal (99.5%) was similar to that obtained in the combined process, but DOC and COD removals were lower (66.5 and 65.1%, respectively). An improvement of the wastewater biodegradability was observed in such condition: the specific oxygen uptake rate and BOD:COD ratio increased from < 0.2 to 17.9 mgO2/(gVSS.h)) and from ~0 to 0.40, respectively. The effluent toxicity also decreased, from 97 to 29% (30 min contact time), allowing the subsequent integration of a biological process.
A relationship between technostress, satisfaction at work, organizational commitment and demography: evidence from the Brazilian public sector

The literature is full of works that highlight the positive effects of the application of information technology on business processes, including gains in terms of transparency, efficiency and effectiveness. However, there is a growing number of studies showing that, in parallel with technological innovation, phenomena occur that cause distress and malaise to the workers, with studies on technostress being highlighted, that is, the difficulty of adapting to technological innovations in the work environment. However, few studies have been carried out to understand the negative effects of this technological transformation on public servants. Thus, the objective of this study is to identify the role of technostress on job satisfaction and organizational commitment in the context of the public sector. The technique of analysis of structural equations (CB-SEM) to analyze data collected with users of information technology from a Brazilian public organization. We have identified that the technostress negatively affects the satisfaction, which, in turn, positively impacts the commitment. In a complementary way, the relation between the demographic characteristics of the workers and the creators of technostress are presented in detail. As a result, several theoretical and practical implications are also discussed.
Thermodynamic Modeling of the Mg-Al-Li-Na-H System for Solid State Hydrogen Storage Applications

In this work a thermodynamic database describing the Mg-Al-Li-Na-H system was constructed using thermodynamic modeling through the CALPHAD method. The constructed database was used to assess the hydrogen storage properties of the system at different pressures and temperatures and to understand the phase relationships and reactions mechanisms. The liquid phase in the binary systems was reassessed using the modified quasichemical model (MQM) or taken from the literature. Since hydrogen atoms occupy the interstitial positions in the solid phases, terminal solid solution phases were described using the compound energy formalism (CEF). Two sublattices were used where Mg, Al, Li, and Na atoms mix randomly in the first sublattice to allow for their mutual solubility and H atom and vacancy mix in the second sublattice. All the gases included in this study were considered ideal. The calculated phase diagrams and thermodynamic properties were compared to experimental data from the literature and showed good agreement. The ternary systems were extrapolated from the corresponding binaries using the asymmetric Kohler-Toop technique where H is singled out as the asymmetric component. In this study, all the calculations were performed using the FactSage software where all the cited models are already coded and implemented. The constructed database allowed the calculation of pressure-composition isotherms of MgH2-10 wt. % NaH, Mg-10 at. % Al and Mg-4 at. % Al. Phase diagrams, pressure temperature diagrams, and reaction pathways of the composites MgH2-AlH3, MgH2-NaAlH4, MgH2-Na3AlH6, and MgH2-AlLiH4/AlLi3H6 were calculated and showed good agreement with the experimental data from the literature. The results provided more details about the de/hydrogenation processes, the amount and composition of phases, and the effect of the pressure and temperature. It is found that Al and Li when added to Mg improve the hydrogen potential of the system and the most promising compositions were predicted. The strategy used in this study will allow the experimental investigations to focus on the kinetics aspect of the de/hydrogenation reactions for these alloys.
The application of a synthetic measure in the assessment of the financial condition of LGUs in Poland using the TOPSIS method approach

An assessment of the financial condition of local government units (LGUs) is usually carried out in a manner referring to traditional tools and methods based on financial analysis. However, it turns out that this approach is unreliable. There are known examples of LGUs, which, despite current reporting concerning their financial situation to the authorities controlling their financial economy, not only did not avoid financial problems (see Rewal, Dziwnów, Byczyna communes), but as a result of the improper management of public funds they were liquidated (e.g., Ostrowice commune). The finding presented above raises pertinent questions about the effectiveness of the current way of assessing the financial condition of local government units and on this basis arriving at conclusions and estimations relating to the possible consequences of the situation in local finance for the future of LGUs. Given the above, attempts to develop new solutions to assess the financial situation of LGUs are becoming more frequent. The aim of this article is to build a synthetic measure for the assessment of the financial condition of communes with regard to all basic statistics describing local government finances and making use of the TOPSIS methodology. The constructed measure does not focus on the estimation of individual financial measures but rather takes into account their interrelationships and interactions. It eliminates the problem of the lack of relationships between the analyzed result values, which may be responsible for the incorrect interpretation of the financial conditions of local government units. The value of the obtained measure allows for an objective assessment of the condition of LGUs finances, providing synthetic information concerning the multi-sectional assessment of the condition of local government finances.
THE INFLUENCE OF BOARD INDEPENDENCE AND INTERNAL AUDIT FUNCTION ON COMPANY’S PERFORMANCE, STUDY OF MACEDONIAN COMPANIES

Corporate governance and company performance are issues that continue to raise interests of the researchers worldwide, as they provide valuable lessons for vast audience, such as company owners, company leaders, supervisors and policy makers. This study aims towards contributing to the previous literature showing that there is positive correlation between corporate governance mechanisms and company performance. It specifically focuses on the correlation between board independence and internal audit function existence with performance of the companies listed on the Macedonian Stock Exchange, for specific periods 2003-2004 vs. 20142018. In particular, the influence of the board independence and the internal audit function over company performance are investigated through Profit, Return on Equity (ROE) and Earnings per Share (EPS) indicators. The results of the performed research and analysis suggest that corporate governance is important for the company performance, i.e. corporate governance improvements such as board member independence and internal audit function have positive impact on the performance of the companies listed on the Macedonian Stock Exchange. However, given the fact that, other factors apart from board member independence and internal audit function can influence the Profit, ROE and EPS of companies, it is reasonable to assume that the increase of profit and of ROE and EPS indicators may not be connected exclusively with having independent board members and internal audit function. First and foremost, this study is of interest for company owners and leaders; yet, it also provides useful information for supervisors and other policy makers.

Keep a minimum distance from other people of 1 meter, if using public transportation, if driving using your own helmet, as much as 100%. Keeping a minimum distance from colleagues of 1 meter as much as 84.2%, not shaking hands when meeting colleagues or relations as much as 68.4%. In general, the application of health protocols using masks, washing hands with soap / hand sanitizer, maintaining distance when leaving for work, during work and when returning home by sanitarians is very high.
Impact of a Novel Boar Pheromone on Weaned Sow Behavior and Reproduction

BackgroundReproductive performance on commercial farms depends on the ability to identify sexual behavior and breed females during estrus. The presence of a boar is essential in determining sow sexual behaviors and is greatly mediated by the adult boar odor. This study sought to examine the effects of a novel boar salivary pheromone on weaned sow sexual receptivity and subsequent reproductive performance. MethodsOne hundred weaned sows were randomly assigned to either a control treatment where sows were exposed during heat detection to a live mature boar (BG) or to BOARBETTER® (Vétoquinol, Lure, France), given as a single spray while a boar grunting audio file was played (PG). Sexual behaviors were assessed twice daily during a Back-Pressure Test (BPT). Sows expressing behavioral estrus were mated. Ultrasound was used to assess ovarian activity from weaning until the end of ovulation. Reproductive and prolificacy data were collected until farrowing.ResultsTwelve sows were eliminated from the study because of early ovulation, no ovulation, or infectious disease. Breeding rate did not differ between the two treatments (BG: 100% vs PG: 91%). Sows in the BG had a shorter wean-to-estrus interval (97 vs 108 h) and longer estrus duration than PG sows (57 vs 39 h; p < 0.05). Wean-to-ovulation interval did not differ but onset of estrus to ovulation interval was longer in PG compared with BG sows (40 vs 30 h, p < 0.01). Follicle size at the onset of estrus was larger among PG than BG sows (5.76 vs 5.43 mm, p = 0.04). Timing of ovulation relative to insemination did not differ between the two treatment groups. Pregnancy rates were identical or similar for sows in the two treatment groups (93%) as was number of pigs born per litter.ConclusionsExposing weaning sows to the novel pheromone and the boar grunting sound achieved high estrus detection rate. Estrus was delayed and shortened but sows were successfully bred and were farrowed. Despite the absence of teaser boar, the procedure incorporating the novel pheromone and the boar grunting sound was shown to be efficient for sow breeding.
Antimicrobial activity of combined thyme and rosemary essential oils against Listeria monocytogens in Italian mortadella packaged in modified atmosphere

Abstract Listeria monocytogenes has been reported as a cause of illnesses related to the consumption raw and processed foods, contaminated during and/or after processing. The ability of L. monocytogenes to multiply at 4°C makes the occurrence in ready-to-eat (RTE) of particular concern. Nowadays, different strategies are applied in order to control pathogens in food products and in particular on the use of essential oils (EOs). The inhibitory effect of thyme and rosemary EOs (0.025% and 0.05%) was determined on a mix of three strains of L. monocytogenes in Italian mortadella packaged in modified atmosphere and stored at 4°C for 30 days. Thymol and p-cymene were the main components of thyme EO, while α-pinene, camphor and eucalyptol of rosemary EO. The use of combined rosemary and thyme EOs exhibited bacteriostatic activity against L. monocytogenes. After 30 days of storage L. monocytogenes charges in treated samples was lower of 2.29 log CFU/g in Group A and 2.79 log CFU/g in Group B compared with control samples. The sensory evaluation, showed the permanence of a strong odor related to EOs used. This work shows that the combined use of thyme and rosemary EOs could be used to control L. monocytogenes in mortadella.

A Comparative Study of Dyslexia Style Guides in Improving Readability for People With Dyslexia

Dyslexia is a cross-cultural complex learning disability that mainly affects the visual structure region of the human brain. The main characteristic is quite distinctive such as seeing words as if they seem doubled, overlapped, irregular, moved, danced, faded, swirled, and even bounced or jumped out of the page which is termed as visual-perceptual distortion. Since 1887, some researchers have tried to discover the most beneficial methods to accommodate people with dyslexia in spelling and reading. In response to this, British Dyslexia Association published Dyslexia Style Guides in 2018, which aimed to ensure that written material considers the difficulties experienced by individuals with dyslexia who estimated around 10% in the world. This was also echoed in Indonesia as the fourth South-east Asian countries based on disability prevalence, where approximately 1 out of 5 people sustained linguistic or learning difficulties. This research was addressed to analyse the BDA Dyslexia Style Guides and perceive its effectiveness through a comparative study with other past research.
Are Lactational Breast Abscesses caused by Methicillin-resistant Staphylococcus aureus Special?

Background: This study aimed to identify the differences in clinical characteristics, puncture efficacy, antibiotic use, treatment duration, breastfeeding postillness, and recurrence of patients with breast abscesses caused by methicillin-resistant Staphylococcus aureus (MRSA) or methicillin-susceptible Staphylococcus aureus (MSSA) infection during lactation.Methods: The clinical data of patients with breast abscesses during lactation who were treated in our hospital from January 2014 to February 2017 were reviewed. According to bacterial culture results, they were divided into MRSA (n = 260) and MSSA (n = 962) groups. Hospitalization (whether or not the patients were hospitalized), postpartum time, age, location of abscess cavities, number of abscess cavities, amount of pus, frequency of needle aspiration, failure of needle aspiration, antibiotic use, treatment duration, delactation and recurrence were compared between the two groups using a t-test and a chi-squared test.Results: We noted that only delactation was statistically significantly different between the two groups (P = 0.018). Hospitalization, postpartum time, age, location of abscess cavities, number of abscess cavities, amount of pus, frequency of needle aspiration, failure of needle aspiration, antibiotic use, treatment duration and recurrence showed no statistically significant differences (P = 0.488, P = 0.328, P = 0.494, P = 0.218, P = 0.088, P = 0.102, P = 0.712, P = 0.336, P = 0.512, P = 0.386 and P = 0.359, respectively). Conclusion: Patients with breast abscesses caused by MRSA infection during lactation presented no significant differences in the clinical manifestations, needle aspiration efficacy, antibiotic use or treatment duration compare with those caused by MSSA infection. However, patients with MRSA infected were more susceptible to delectation.
