Nutrient removal in a slow-flowing constructed wetland treating aquaculture effluent

Danish model trout farms (MTFs) use stream-like constructed wetlands for effluent polishing, and the industry is keen to improve wetland removal efficiency. To facilitate this, we examined longitudinal and seasonal nutrient removals in an MTF wetland with a hydraulic retention time (HRT) of 1.7 d, a free water surface (FWS) area of 7510 m2, and a volume of 6008 m3. Biweekly, 24-h composite water samples were obtained for 1 yr at 6 sampling stations along the wetland. Assuming plug flow conditions, reductions in particulate and dissolved nutrient concentrations were modelled as first-order removal processes, and removal rate constants (k1,A, m d−1) were plotted to reveal seasonal fluctuations. Particulate phosphorus and organic matter k1,A fluctuated more or less randomly through the year, reflecting that particulate nutrient removal predominantly takes place by sedimentation. In contrast, dissolved nitrogen, phosphorus, and organic matter k1,A fluctuated seasonally, demonstrating that dissolved nutrient removal relies on biologically mediated processes. Temperature oscillations probably governed the observed seasonal fluctuations in nitrate-N k1,A and could be approximated with an Arrhenius temperature coefficient of 1.07. Furthermore, denitrification appeared to be carbon-limited. Incoming dissolved phosphorous and ammonia became incorporated in the natural wetland growth cycle that in cluded periods of net removal and release, resulting in minimal annual net removal. In summary, this study shows that improving nitrate removal in a slow-flowing MTF wetland would require some kind of carbon dosing, while further improving ammonia and phosphorus removal would require a reduction of the amounts of ammonia and dissolved phosphorus entering the wetland.
Propagation of radar rainfall uncertainties into urban pluvial flood modeling during the North American monsoon

ABSTRACT Pluvial flooding in urban regions is a natural hazard that has been rarely investigated. Here, we evaluate the utility of three radar (Stage IV, Multi-Radar Multi-Sensor or MRMS, and gauge-corrected MRMS or GCMRM) quantitative precipitation estimates (QPEs) and the Storm Water Management Model (SWMM) hydrologic–hydraulic model to simulate pluvial flooding during the North American monsoon in Phoenix. We focus on an urban catchment of 2.38 km2 and, for four storms, we simulate a set of flooding metrics using the original QPEs and an ensemble of 100 QPEs characterizing radar uncertainty through a statistical error model. We find that Stage IV QPEs are the most accurate, while MRMS QPEs are positively biased and their utility to simulate flooding increases with the gauge correction done for GCMRMS. For all radar products, simulated flood metrics have lower uncertainty than QPEs as a result of rainfall–runoff transformation. By relying on extensive precipitation and basin datasets, this work provides useful insights for urban flood predictions.
Interactive Effects of Stoicism and Religious Coping on Psychological Distress, Fatigue and Intercultural Communication: Muslim Health Workers in Bali

The rapid transmission of Covid-19 posed threats and challenges for people all around the world. Based on self-ownership theory, the current study tested the interactive effect of positive religious coping and stoicism in decreasing psychological distress and physical fatigue and increasing intercultural communication among Muslim health workers. This study advances the body of literature regarding coping mechanisms in the form of stoic believes and religion to decrease the stressors during disastrous situations like the COVID-19. Using a longitudinal field survey, data were collected from 243 Muslim health workers performing their duties at various public and private hospitals and medical centers in Bali, Indonesia. Data were analyzed using SmartPLS software. The results revealed that interactive effects of positive religious coping with stoicism helped decrease psychological stress and physical fatigue and increase intercultural communication among Muslim health workers during Covid-19. The study contributed to the body of knowledge regarding the role of religious practices and stoicism in building coping mechanisms among Muslim health workers to sustain themselves in a challenging environment.
Modelling spanwise heterogeneous roughness through a parametric forcing approach

Abstract Inhomogeneous rough surfaces in which strips of roughness alternate with smooth-wall strips are known to generate large-scale secondary motions. Those secondary motions are strongest if the strip width is of the order of the half-channel height and they generate a spatial wall shear stress distribution whose mean value can significantly exceed the area-averaged mean value of a homogeneously smooth and rough surface. In the present paper it is shown that a parametric forcing approach (Busse & Sandham, J. Fluid Mech., vol. 712, 2012, pp. 169–202; Forooghi et al., Intl J. Heat Fluid Flow, vol. 71, 2018, pp. 200–209), calibrated with data from turbulent channel flows over homogeneous roughness, can capture the topological features of the secondary motion over protruding and recessed roughness strips (Stroh et al., J. Fluid Mech., vol. 885, 2020, R5). However, the results suggest that the parametric forcing approach roughness model induces a slightly larger wall offset when applied to the present heterogeneous rough-wall conditions. Contrary to roughness-resolving simulations, where a significantly higher resolution is required to capture roughness geometry, the parametric forcing approach can be applied with usual smooth-wall direct numerical simulation resolution resulting in less computationally expensive simulations for the study of localized roughness effects. Such roughness model simulations are employed to systematically investigate the effect of the relative roughness protrusion on the physical mechanism of secondary flow formation and the related drag increase. It is found that strong secondary motions present over spanwise heterogeneous roughness with geometrical height difference generally lead to a drag increase. However, the physical mechanism guiding the secondary flow formation, and the resulting secondary flow topology, is different for protruding roughness strips and recessed roughness strips separated by protruding smooth surface strips.
Genomic differentiation with gene flow in a widespread Amazonian floodplain‐specialist bird species

Ecological, climatic and palaeogeographical processes drive biological diversification. However, the evolutionary outcomes of those mechanisms are complex and difficult to discriminate. Here, we test how alternative drivers affected connectivity along the Amazonian floodplains generating current patterns of population structure and diversity within the Striped Woodcreeper, a widespread bird species tied to forests seasonally flooded by Amazonian rivers.
Online Sentence Processing During Reading of Temporally Ambiguous Gapping Sentences in Brazilian Portuguese / Processamento online na leitura de sentenças elípticas gapping com ambiguidade temporária no Português Brasileiro

Abstract: This article aims to explore whether the online sentence processing of gapping sentences, with a temporary ambiguous DP at the second conjunct, such as “Beatriz baked a pizza and Carla a lemon cake for snack”, is more costing in terms of time course in comparison to other two coordinated sentences, coordinate with conjoined object such as “Beatriz baked a pizza and a lemon cake for snack in the afternoon”, and coordinate with conjoined clauses without ellipsis, such as “Beatriz baked a pizza and Carla made a lemon juice”. A Self-Paced Reading task in moving-window fashion was carried out with native speakers of Brazilian Portuguese. The results seem to indicate that temporary ambiguous DP and the resolution of the ellipsis site were more costly to process int comparison to the other two coordinated sentences.Keywords: Sentence Processing; Ellipsis; Gapping; Brazilian Portuguese. Resumo: Este artigo tem como objetivo explorar se o processamento online de sentenças elípticas gapping, com ambiguidade temporária do DP que inicia a segunda oração, como em “A Beatriz assou a pizza e a Carla o bolo de limão pro lanche”, é mais custoso em comparação com outros dois tipos de sentenças coordenadas, estrutura com coordenação de objetos como em “A Beatriz assou a pizza e o bolo de limão pro lanche da tarde”, e estrutura com sentenças coordenadas sem elipse, como em “A Beatriz assou a pizza e a Carla preparou um suco de limão”.

Re-Negotiating National Identity Through Chinese Fashion

Abstract As cultural and creative industries have been used by china to modernize the country, it is critical to talk about the emergence of new creative subjectivity. The lack of creative agency in China is a deficit position from which these industries began to gain attention within the policy circle. Much of the research and understandings on Chinese creative industries have been at the periphery of scholarly discussion on agency, identity, social class and so on. It has not been concerned with the question of how creatives deal with the conflicts between economic rationality and cultural esthetics. O’Connor and Gu’s research in China on this is an exception (c.f. O’Connor and Gu). In relation to fashion, scholarly attentions concern overwhelmingly with national identity (c.f. Tsui; Clark; Kunz) rather than how fashion identity is increasingly shaped by universal cultural values. Segre-Reinach’s works on the influence of international fashion industry (esp. Italian fashion) on Chinese national identity are of particular interests here (c.f. 2009). In this paper, we explore meaning making process within the emergent sustainable fashion field, drawing interests primarily from small independent labels in China. Their attempts to connect with universal cultural values in the field of sustainable fashion are testimonies to how creative subjectivity is evolving within contemporary China. We argue that whether Chinese creatives are going to break through is dependent on the following three aspects: availability of a symbolic space nurturing source of imaginary for creative subjectivity; the exchange structures attached to local imaginaries; and creative’s esthetic reflexivity framed by sense of belonging to this symbolic space—“Chineseness”.
New Electronically Tunable Third Order Filters and Dual Mode Sinusoidal Oscillator Using VDTAs and Grounded Capacitors

This study introduces a third order filter and a third order oscillator configuration. Both the circuits use two voltage difference transconductance amplifiers (VDTAs) and three grounded capacitors. By selecting the input and output terminals properly, current mode and transimpedance mode low-pass and band-pass filters can be obtained without component matching conditions. The natural frequency (ω0) can be tuned electronically. The oscillator circuit provides voltage and current outputs explicitly. The condition of oscillation (CO) and the frequency of oscillation (FO) can be adjusted orthogonally and electronically. The workability of the configurations is judged using TSMC CMOS 0.18 μm technology parameter as well as commercially available LM13700 integrated circuits (ICs). The simulation results show that: for ±0.9V power supply, the power consumption is 1.08 mW for both the configurations, while total harmonic distortions (THDs) are less than 2.06% and 2.17% for the filter and oscillator configurations, respectively.
Knowledge, attitude, and practice towards patient safety culture among primary health care physicians in training centers at cluster one in Riyadh, Kingdom of Saudi Arabia

Background: Patient safety is a global concern among healthcare providers. However, the challenges to and the future of patient safety have not been explored in details at primary health care centers in recent literature in the Kingdom of Saudi Arabia. The World Health Organization (WHO) defines patient safety as “the prevention of errors and adverse effects to patients associated with health care” and “to do no harm to patients”. The study aims to identify and analyze factors that influence patient safety culture in the primary health care setting. Methodology: A cross-sectional study was conducted on primary health care physicians working in 12 primary health care training centers, cluster one, ministry of health, Riyadh city, Kingdom of Saudi Arabia, over a period of two months from the beginning of January, 2021 to the end of February, 2021 using a survey inspired from Hospital Survey on Patient Safety Culture (HSOPS). The HSOPS was developed by the Agency for Healthcare Research and Quality (AHRQ) in 2004 and has been translated into around 20 different languages. The questionnaire was answered by all primary health care physicians who accepted to be included in this study. The data was analyzed by Statistical Package for the Social Sciences (SPSS) latest version program. Results: In this study, the response rate was 94.55% and we were able to collect 208 responses of our questionnaire among primary health care physicians with 75% of the physicians were Saudis. 53.4% of the responders were males. The overall average positive response rate for the patient safety culture dimensions was 76.13%. Moreover, we found that 48.1% of the participants rated the procedures to achieve patients’ safety is very good while 32.2% of them reported excellent patients’ safety. Moreover, we found that almost half of the physicians (46.2%) reported no event reports in the last 12 months while 28.8% reported 1 -2 events, 20.2% reported 3-5 events and only 1% reported 11-20 event in the last 12 months. Conclusion: The patient safety culture in primary health care facilities in Riyadh city, Kingdom of Saudi Arabia is good and gives better results than previous studies.
CORN AND ALEXANDERGRASS INTERCROPPING SYSTEM: INFLUENCES OF HERBICIDE MANAGEMENT ON GRAIN AND FORAGE YIELD

At Southern Brazil, intercropping system between corn and Urochloa is an interesting way to improve soil cover and animal feed. This study was carried out with the objective to evaluate the effect of herbicides and its doses on corn and Alexandergrass (Urochloa plantaginea) yield, in an intercropped system. The experiment was arranged in a randomized block design, with four replications in a factorial scheme. First factor was composed of four herbicide associations: (1) Atrazine + Oil; (2) Atrazine + Simazine + Oil; (3) Atrazine + Nicosulfuron + Oil; (4) Atrazine + Mesotrione + Oil. The second factor was composed of three doses of these herbicide combinations: 100%, 75% and 50% of the recommended dose to control Alexandergrass. A control treatment without herbicide spraying was evaluated. Corn crop was sowed in no-till system and Alexandergrass established by self-seeding. Herbicide management in corn and Alexandergrass intercropping system is primordial to obtain good grain yields, once corn was highly affected by the forage. Herbicides and doses influenced Alexandergrass forage yield, although, all the managements allow forage availability after corn harvest. 75% of the recommended dose of Mesotrione and Nicosulfuron associations promoted the better corn yields in the consortium, with adequate Alexandergrass forage production.
The (in)significance of citizenship in white British citizens’ narratives of national belonging

ABSTRACT This paper investigates the relationship between citizenship and belonging through empirical analysis of citizens’ narratives. Specifically, through analysis of interview narratives produced with twenty-six white British citizens, the paper explores whether/how citizenship is recognised as a basis for national membership by those for whom citizenship and national belonging are largely taken for granted. In doing so, the paper sheds new light on the meaning and significance of citizenship within informal economies of national belonging and draws critical attention to the role of discursive recognition in sustaining hierarchies of belonging. The paper finds that formal status has limited significance as a practical marker of belonging and that, even where citizenship is constructed as significant, its significance is often undermined. It concludes that citizenship on its own is insufficient to guarantee substantive national belonging in the sense of being recognised and included as belonging to a national community and does not necessarily legitimise more ambiguous claims to national belonging.
Surface Wettability Controllable Polyimides Having Various Photoreactive Groups by Photo-irradiation

The soluble polyimides were synthesized from tetracarboxylic dianhydrides such as 3,4'-oxydiphthalic anhydride (3,4’-ODPA) and diamine monomers having various photoreactive groups, which are photo-oxidative groups, photoreaction groups based on photoresist technology, and photochromic groups. The thin films of obtained polyimides were irradiated by UV light (λ max; 254 nm or 365 nm), and the contact angles for the water decreased from near 100° (hydrophobicity) to minimum 20° (hydrophilicity) in proportion to irradiated UV light energy. The reversible wettability changes of the polyimides having photochromic groups by UV-Vis light irradiation were also investigated. Various surface analysis such as ATR, solid state refractive UV, XPS support above surface wettability changes of the polyimides.

Campomanesia spp. native fruits as potential source of health-promoting compounds

Campomanesia xanthocarpa var. littoralis, Campomanesia xanthocarpa (Berg), and Campomanesia eugenioides are native fruit plants found in Brazil. Due to the scarce number of controlled scientific studies comparing different native Campomanesia species, this study sought to determine their bioactive compounds and antioxidant properties. C. eugenioides proved to be a rich source of total phenolic compounds, also showing the best antioxidant capacity by the ABTS, DPPH and molybdenum reduction power methods. On the other hand, C. xanthocarpa var. littoralis showed the best results for total flavonoids content, and Iron(II) chelation power. The phenolic compounds contents present in C. eugenioides could be responsible for the best antioxidant activity. This study provides key scientific data regarding the use of valuable fruits from different edible Campomanesia species to produce bioactive ingredients, as well as natural preservatives for food products. Thus, our results contribute to the discovery of the potential application of these native Campomanesia Brazilian fruits, as a natural product with functional and antioxidant properties.

New results of numerical simulations and analytical estimations of the energy into gas deposition due to NS SDBD driven by a single NS voltage pulse are presented. The problems relating to NS SDBD modelling are discussed.
Cloud Forming Potential of Aerosol from Light-duty Gasoline Direct Injection Vehicles

In this study, the authors evaluate the hygroscopicity and droplet kinetics of fresh and aged emissions from new generation gasoline direct injector engines retrofitted with a gasoline particulate filter (GPF). Furthermore, ageing and subsequent secondary aerosol formation is explored in (NH4)2SO4-seeded and non-seeded experiments. The authors explore the impacts on measured and predicted hygroscopicity, CCN-activity, and droplet kinetics of secondary aerosol mixed with initially insoluble carbonaceous materials versus very soluble (NH4)2SO4 seed. The chemical composition and density of the secondary aerosol (SA) formed from aging is measured with an HR-TOF-AMS and a custom-built APM-SMPS system. The supersaturated and subsaturated hygroscopicity of the fresh and aged emission is measured with a DMT Streamwise Thermal Gradient CCN counter and a hygroscopicity tandem differential mobility analyzer (HTDMA), respectively. The measurements show that the fresh gasoline emissions are only slightly hygroscopic in both supersaturated and subsaturated environments. Photochemical aging and subsequent condensation of the secondary aerosol formed from the co-emitted gas phase precursors increases the hygroscopicity of gasoline emissions. Without the GPF, both subsaturated and supersaturated hygroscopicity. When the engine was retrofitted with the GPF, the secondary aerosol (SA) experiments were seeded with (NH4)2SO4. In these experiments the presence of the condensing SA depresses the hygroscopicity of the salt-secondary aerosol mixture. The hygroscopicity was also depressed in the subsaturated regime with time. These changes in the hygroscopicity with aging were additionally sensitive to aerosol dry size distribution. The authors also used threshold droplet growth analysis (TDGA) to evaluate the effects of the condensing SA on droplet kinetics. These results have important implications for the assessment of cloud-aerosol indirect effects of salt-seeded and black carbonaceous aerosol cores. The authors concluded that in the new generation GDI vehicles the point of aerosol emissions will have significant influence on the impacts of the secondary and primary aerosols on climate.
Effect of feedstocks and chain length of alcohols on whole-cell-catalyzed generation of alkyl esters

ABSTRACT The dried biomass of a whole-cell catalyst was used for the generation of alkyl esters from cottonseed oil and acid oil with different alcohols (methanol to decanol) as acyl acceptors. The conversion of alkyl esters increased from methanol (12%) to pentanol (96%), followed by decreased from hexanol (86%) to decanol (64%) in case of acid oil. The extent of transesterification was significantly higher (P < 0.01) in case of acid oil, with most of the acyl acceptors as compared to cottonseed oil. The study demonstrates the use of dried biomass of fungus as catalyst and an effective feedstock such as acid oil, for the generation of various industrially important alkyl esters.
