Spatial Patterns of Macrozoobenthos Assemblages in a Sentinel Coastal Lagoon: Biodiversity and Environmental Drivers

This study presents an assessment of the diversity and spatial distribution of benthic macrofauna communities along the Moulay Bousselham lagoon and discusses the environmental factors contributing to observed patterns. In the autumn of 2018, 68 stations were sampled with three replicates per station in subtidal and intertidal areas. Environmental conditions showed that the range of water temperature was from 25.0 °C to 12.3 °C, the salinity varied between 38.7 and 3.7, while the average of pH values fluctuated between 7.3 and 8.0. In vegetated habitats, biomass values of the seagrass Zostera noltei Hornemann ranged between 31.7 gDW/m² and 170.2 gDW/m² while the biomass of the seagrass Ruppia cirrhosa (Petagna) Grande between 54.2 gDW/m² and 84.7 gDW/m². Sediment analyses showed that the lagoon is mainly composed of sandy and silty sediments. We recorded 37,165 individuals of macrofauna distributed in 63 taxa belonging to 50 families, with a mean abundance value of 4582.8 ind/m² and biomass average of 22.2 g/m². Distance-based linear modeling analysis (DISTLM) identified sediment characteristics, water parameters and habitat type (biomass of Z. noltei) as the major environmental drivers influencing macrozoobenthos patterns. Our results clearly revealed that the hydrographic regime (marine and terrestrial freshwater), sediment distribution and characteristics and the type of habitat (vegetated vs. unvegetated substrate) are the key factors determining the species composition and patterns of macrozoobenthos assemblages.
Effects of intermittent chemical dosing on volatile sulfur compounds in sewer headspace

Volatile sulfur compounds (VSCs), including hydrogen sulfide (H2S) and volatile organic sulfide compounds (VOSCs), can be produced in sewer systems causing sewer odor problems. In this study, the effects of intermittently dosing ferric iron, hydrogen peroxide, and nitrate on H2S and VOSCs in sewer headspace were investigated. In order to characterize the composition of VSCs, an HC-3 trace sulfur analyzer and gas chromatograph (GC) equipped with a triple quadrupole-type mass spectrometry (MS) apparatus were used to determine the VSCs. The results indicated that the effect of intermittent addition of 40 mg/L ferric iron or 40 mg/L hydrogen peroxide is limited for VSCs inhibition. The H2S and VOSCs concentrations increased significantly in the late-stage experiments, even around 20% and 30% respectively higher than the initial average concentrations. However, the intermittent addition of 40 mg N/L nitrate has a relatively stable control effect of H2S and VOSCs which maintaining 60% removal rate. Moreover, methyl mercaptan (MeSH) was the most abundant compound of the total VOSCs released and the results of the theoretical odor concentration study also indicate MeSH is the main VOSC causing the significant odor problem. Therefore, more attention should be focused on the VOSCs which have extremely low odor threshold.
Etiopathogenesis of schizophrenia – the state of the art for 2021

In 2021, one-hundred and ten years passed since a Swiss psychiatrist, Eugen Bleuler, introduced a term ‛schizophrenia’, denoting one of the most severe and stigmatizing psychiatric illnesses. Presently, it is known that the etiopathogenesis of schizophrenia is multifactorial, and a neurodevelopmental theory has been the most important pathogenic concept for more than 30 years. The theory postulates an interaction between genetic predisposition and environmental factors. In recent years, mainly thanks to employing the genome-wide association studies (GWASs), many molecular-genetic processes increasing a predisposition to schizophrenia have been identified. In the article, the role of pregnancy and perinatal period for risk of developing schizophrenia was considered. In patients with schizophrenia, as early as in childhood and adolescence, the disturbances of brain development occur, reflected, among others, by an impairment of cognitive functions. Childhood trauma makes a risk factor for developing schizophrenia and a less favorable course of the illness. The arising of the first psychotic episode is boosted by socio-environmental factors (e.g., migration, urbanicity) and psychoactive substance use, both increasing dopaminergic activity of the brain. In the paper, contemporary knowledge on the pathogenesis of psychotic and deficit symptoms and disturbances of cognitive functions was presented. This was done concerning the neurotransmitters’ changes and genetic and neuroimaging studies, with emerging therapeutic implications. At the end of the article, a current position of schizophrenia in the context of dichotomic division of mental disturbances put forward by Emil Kraepelin in 1899 was discussed.
Diffusion of isobutane in silicalite: a neutron spin-echo and molecular dynamics simulation study

The diffusion of isobutane in silicalite was studied using neutron spin–echo (NSE) experiments and molecular dynamics (MD) simulations between 444 and 550 K. The experimental and simulated diffusion coefficients showed agreement well within an order of magnitude, as did the activation energies of diffusion which agreed to within 3.4 kJ mol–l (∼15%). Jump diffusion was observed by NSE with a jump distance of 10 A, also observed by the MD simulations showing that the residence time was spent in a small section of the sinusoidal channel, rather than the intersections between channels as reported in previous simulations. The level of sinusoidal trapping diminishes in the simulations with increasing temperature, where the isobutane develops isotropic diffusion through both channel systems, as observed by NSE experiments.
N2 oxidation kinetics in a ns-pulsed discharge above a liquid electrode

In this work, the kinetics of nitrogen fixation via plasma-induced N2 oxidation in a 10 ns pulsed atmospheric pressure water-contacting discharge sustained in air is investigated. Two pulse regimes, a single pulse and a three-pulse burst of 100 kHz, are considered. The densities of relevant radicals (NO, O) are studied by time- and space-resolved laser-induced fluorescence spectroscopy. It is concluded that in a single pulse mode, O atoms are mainly generated by O2 reacting with electronically excited states of N2 ( A3Σu+,B3Πg,C3Πu ) and are primarily reduced as a result of O3 formation. The O density shows a maximum at ∼100 ns after the plasma pulse with number density of ∼1023 m−3. NO radicals, on the other hand, are primarily formed by reacting with the N2A3Σu+ state (up to ∼1 μs after the pulse) and with OH radicals (up to ∼10’s of μs), peaking at approximately 60 μs with a peak density of ∼1021 m−3. The NO loss pathway is represented by the reversed Zeldovich mechanism at short time delays (∼10’s μs), whereas at longer delays (>100’s of μs) HNO2 and NO2 formation causing NO loss start to be dominant. In the burst mode, the energy efficiency of NO formation decreases despite higher N2 conversion, for which three reasons are suggested: (1) NO removal by the generated O(D1) after the discharge pulse through the reverse Zeldovich mechanism, (2) NO oxidation via the accumulated O3, (3) pre-ionization induced by high pulse repetition rate (100 kHz) leading to shrinkage of the plasma bulk.
Cyclical Worker Flows: Cleansing vs. Sullying

Do recessions speed up or impede productivity-enhancing reallocation? To investigate this question, we use U.S. linked employer-employee data to examine how worker flows contribute to productivity growth over the business cycle. We find that in expansions high-productivity firms grow faster primarily by hiring workers away from lower-productivity firms. The rate at which job-to-job flows move workers up the productivity ladder is highly procyclical. Productivity growth slows during recessions when this job ladder collapses. In contrast, flows into nonemployment from low productivity firms disproportionately increase in recessions, which leads to an increase in productivity growth. We thus find evidence of both sullying and cleansing effects of recessions, but the timing of these effects differs. The cleansing effect dominates early in downturns but the sullying effect lingers well into the economic recovery.
Medical Errors Disclosure Practices, Barriers and Motivations to Disclosures Among Physicians in Tertiary and Secondary Health Facilities in Abuja Nigeria

The disclosure of medical errors is very important in ensuring the quality of patient care and safety. However, the disclosure practices by physicians are not well documented in this setting. The objective of this study is to compare the disclosure practices as well as the motivations and barriers to disclosure of these errors among physicians in government secondary and tertiary health facilities in Abuja, Nigeria. A cross sectional survey of physicians working in six out of fourteen government hospitals was conducted. A cluster sampling technique of the hospitals as the clusters was employed to obtain the total sample size of 402 physicians, 201 for each level. A semi structured, self-administered questionnaire was used to collect quantitative data on near misses, mistakes, slips or lapses and technical errors. Data was analysed using SPSS version 15.0 and summarised as proportions. Chi-square test was used to assess associations between variables at a significance level of 5%. Also logistic regression analyses were used to determine the significant predictors of medical error occurrences and disclosures. Some 255 physicians i.e. (52.6%) from the tertiary level and 230 (47.4%) from the secondary level were interviewed. Both the tertiary and the secondary levels had very poor medical errors disclosure practices, with disclosure of errors that caused patient’s death or disability (3.9 vs. 8.3%, p=0.023); or disclosure of errors that caused discomfort or prolonged treatment to patients (33.2% vs. 21.3%, p=0.026). The major barriers to error disclosures at the tertiary and the secondary health facilities were: lack of malpractice insurance (69.4% vs. 48.2%, p=0.000); lack of policies for disclosing errors (62.4% vs. 55.4%, p=0.119); and the fear of negative patient reactions (56.7% vs. 51.3%, p=0.233). The major motivations to errors disclosure were receiving a positive feedback from the institution (65.1% vs. 56.3%, p=0.048) and the support and understanding of colleagues (50.2% vs. 48.7%, p=0.74). This study suggests poor medical errors disclosure practices. In this study setting, the development of institutional policies on disclosure will motivate physicians’ disclosure of medical errors and this should be encouraged. Such policies should include institutionally administered malpractice insurance for the physicians.
Perceived Stress as A Mediator in The Relationship between Time Perspectives and Alcohol Consumption

Heavy drinking is injurious to health and may even lead to death. Previous studies showed that Past-Negative, Present-Fatalistic, and Future time perspectives influence alcohol consumption; however, this study presents evidence that contradicts these claims. Lazarus and Folkman’s (1984) transactional model of stress and coping explains that cognitive processes, such as perceived stress, are responsible for individual choices of coping strategies or decision to consume alcoholic beverages. Personal factors also influence time perspectives. This study applies the aforementioned model to hypothesize that the relationship between time perspectives and alcohol consumption is mediated by perceived stress. A total of 307 participants aged 18–22 years (late adolescence) who were habitual consumers of alcohol participated in this study. Mediation analysis was employed and it was revealed that perceived stress did not mediate the relationship between Past-Negative and Present-Fatalistic time perspectives and alcohol consumption. However, perceived stress was found to be a mediator in the relationship between Future time perspective and alcohol consumption. To summarize, dominant Past-Negative and Present-Fatalistic time perspectives can cause alcohol consumption in individuals who possess specific characteristics. Conversely, stress can precipitate alcohol consumption for individuals evincing the Future time perspective.
ESG ratings: relevant information or misleading clue? Evidence from the S&P Global 1200

ABSTRACT Environmental, social, and corporate governance (ESG) scores are frequently involved in investment-related decision-making, e.g. for red-flagging or to manage risks. The increasing interest in ESG data raises the question about their validity from various sources. Therefore, we explore the consistency and convergent validity of the well recognized ESG data providers. Exploratory factor analysis of S&P Global 1200 index demonstrates considerable uncertainty across extracted latent factors. Further factor analyses show that the consistency and convergent validity across ESG data significantly depend on the industry type and the country of domicile. These findings are supported by confirmatory factor analyses. Thus, the stakeholders are encouraged to incorporate the company sector and domicile aspects into their decisions. Otherwise, naive use of primary ESG scores may provide a misleading clue.
Percutaneous Coronary Intervention in Post-Infarction Ventricular Septal Rupture

Background: Ventricular septal rupture (VSR) is a fatal mechanical complication following acute myocardial infarction (AMI). The definitive treatment remains surgical repair, however several aspects are still debatable, including the timing of surgery. Patient’s refusal of treatment and lack of medical facilities put other challenges in management of VSR. Case presentation: A-48-year-old male with a history of diabetes mellitus and hypertension came with a late-presentation anterior AMI, and refused the reperfusion therapy. By the third day, he developed VSR and cardiogenic shock. The patient was also against any referral plan for further therapy. Hemodynamic status was optimally controlled with vasopressor and inotropic agents. The patient was discharged with a grade II-III New York Heart Association (NYHA) on the tenth day. In follow up evaluation a week later, the patient presented limb swelling and functional NYHA class III-IV. The patient agreed to received percutaneous coronary intervention (PCI). Drug eluting stent (DES) in left anterior descending (LAD) coronary artery was implanted successfully without defect closure. Follow-up after 12-months revealed no signs or symptoms of decompensated heart failure. Keywords: ventricular septal rupture; percutaneous coronary intervention; acute myocardial infarction
No Association was Detected between Polymorphism of COL1A2 Genes and Occurrence of Dental Fluorosis Among the Subjects Living in a Fluorosis-Endemic Area of India

Objective: To determine any genetic association of COL1A2 polymorphism and the occurrence of dental fluorosis within an Indian human dental fluorosis population. Material and Methods: Fifty-six (56) subjects from two groups i.e. cases with dental fluorosis from the Pavagada population (n=29) and a control group (n=27) without fluorosis, were explored. The ages ranged between 15 and 76 years (mean 50.8 years) were included, and the male to female ratio was 70:30. The severity of dental fluorosis was graded using WHO’s Thylstrup-Fejerskov index (TF), and the concentration of fluoride was determined by a fluoride ion selective electrode (ISE). Genomic DNA was extracted using the standard phenol-chloroform method. The rs412777 and rs414408 polymorphism in COL1A2 were genotyped using the Sanger sequence method. Results: Genotype distributions for rs412777 within each group were: AA 41%, AC 51%, and CC 7% for dental fluorosis participants, and AA 56%, AC 46%, and CC 0% for the control participants. Conclusions: The rs412777 and rs414408 polymorphisms in the COL1A2gene showed no significant association between COL1A2 and the occurrence of dental fluorosis amongst this Indian population.
Binderless bark particleboard made from gelam (Melaleuca viridiflora Sol. ex Gaertn.) bark waste: The effect of the pressing temperature on its mechanical and physical properties

This study investigated the effects of the pressing temperature on the mechanical and physical properties of binderless bark particleboard made from Gelam bark waste and the improvement of those properties. In addition, the thermal insulation properties of the particleboard were determined. Four different temperatures (140 °C, 160 °C, 180 °C, and 200 °C) were used to make single-layer binderless bark particleboard with a target density of less than or equal to 0.59 g/cm3. Results revealed that the pressing temperature affected the mechanical properties (modulus of rupture, modulus of elasticity, and tensile strength perpendicular to panel surface), which increased as the temperature increased, and the physical properties (thickness swelling and water absorption), which decreased as the temperature increased. Based on the Tukey test, increasing the temperature from 180 to 200 °C did not significantly affect the mechanical or physical properties, except for the tensile strength perpendicular to panel surface. None of the mechanical properties met SNI standard 03-2105-2006 (2006); however, the 12% maximum thickness swelling requirement was met for binderless bark particleboard hot-pressed at 200 °C. Binderless bark particleboard hot-pressed at 200 °C had high water resistance, regardless of its low strength, and a thermal conductivity value of 0.14 W/m∙K.
Enhanced Methanol Oxidation Activity of PtRu/C100−xMWCNTsx (x = 0–100 wt.%) by Controlling the Composition of C-MWCNTs Support

PtRu nanoparticles decorated on carbon-based supports are of great interest for direct methanol fuel cells (DMFCs). In this study, PtRu alloy nanoparticles decorated on carbon Vulcan XC-72 (C), multi-walled carbon nanotubes (MWCNTs), and C-MWCNTs composite supports were synthesized by co-reduction method. As a result, PtRu nanoparticles obtained a small mean size (dmean = 1.8–3.8 nm) with a size distribution of 1–7 nm. We found that PtRu/C60MWCNTs40 possesses not only high methanol oxidation activity, but also excellent carbonaceous species tolerance ability, suggesting that C-MWCNTs composite support is better than either C or MWCNTs support. Furthermore, detailed investigation on PtRu/C100−xMWCNTsx (x = 10–50 wt.%) shows that the current density (Jf), catalyst tolerance ratio (Jf/Jr), and electron transfer resistance (Ret) are strongly affected by C-MWCNTs composition. The highest Jf is obtained for PtRu/C70MWCNTs30, which is considered as an optimal electrocatalyst. Meanwhile, both PtRu/C70MWCNTs30 and PtRu/C60MWCNTs40 exhibit a low Ret of 5.31–6.37 Ω·cm2. It is found that C-MWCNTs composite support is better than either C or MWCNTs support in terms of simultaneously achieving the enhanced methanol oxidation activity and good carbonaceous species tolerance.
Transportation technology with pour point depressant and wax deposition in a crude oil pipeline

ABSTRACT The authors systematically studied transportation technology with pour point depressant and wax deposition in an industrial crude oil pipeline. Experiment results manifest that beneficiated oil acquires obvious modification effect and the reheating temperature of intermediate heat stations should be above 55°C to avoid effect deterioration. Heating schemes are made with lower heating temperature and wider output range. Moreover, an applicable wax deposition model is established to predict wax deposition distribution along the pipeline under various operating conditions. Wax deposition rate varies severely along the pipeline and it is necessary to consider its non-uniformity in production.
