Description du sujet. L’étude de la qualité physico-chimique de l’eau vise une connaissance des risques écologiques que l’activité d’extraction du sable peut engendrer sur l’environnement et ses ressources. Objectifs. Évaluer l’impact de l’extraction du sable fluvio-lagunaire sur la qualité physico-chimique de l’eau des écosystèmes aquatiques du sud-Bénin. Méthode. Les données ont été collectées mensuellement de décembre 2018 à novembre 2019 au niveau de 16 stations dont huit stations draguées et huit stations non draguées (stations de références). Treize paramètres physico-chimiques dont neuf paramètres (température, pH, transparence, profondeur, salinité, oxygène dissous, conductivité électrique, Solides Totaux Dissous, vitesse du courant) sont analysés in situ et quatre autres (NO2-, NO3-, NH4+, PO43-) au laboratoire. Le test de Kruskal-Wallis, la Matrice de Corrélation, la Classification Hiérarchique Ascendante et l’Analyse en Composantes Principales (ACP) ont été utilisés pour l’analyse des données collectées. Résultats. Les résultats ont permis d’identifier les effets de l’activité d’extraction du sable sur la physico-chimie de l’eau des écosystèmes aquatiques à travers l’analyse des stations draguées et des stations non draguées. Les stations non draguées présentent des eaux fortement minéralisées associées également à une pollution azotée et phosphorée, ce qui pourrait créer un déséquilibre au niveau de la faune aquatique. Par contre, les stations soumises à l’activité d’extraction du sable présentent les caractéristiques d’eaux bien oxygénées, des pH qui tendent vers la basicité, des eaux bien transparentes et profondes. Les résultats de cette étude montrent que les eaux des milieux dragués sont bien oxygénées et pourraient être bien favorables avec le temps au bon développement des espèces aquatiques, lorsque ceux-ci retrouveront peu à peu leur stabilité et redeviendront riches en matières minérales et nutritives. Conclusions. Cette étude permettra aux chercheurs et aux services techniques en charge de l'environnement de mieux appréhender les effets de l'activité d'extraction du sable sur la qualité physico-chimique des eaux des hydrosystèmes pour une meilleure gestion de ces milieux.
Using diketopyrrolopyrroles to stabilize double excitation and control internal conversion
Authors: T. do Casal Mariana , Toldo Josene M. , Plasser Felix , Barbatti Mario
Published: May 2022

Diketopyrrolopyrrole (DPP) is a pivotal functional group to tune the physicochemical properties of novel organic photoelectronic materials. Among its multiple uses, DPP-thiophene derivatives forming a dimer through a vinyl linker were recently shown to quench the fluorescence observed in their isolated monomers. Here, we explain this fluorescence quenching using computational chemistry. The DPP-thiophene dimer has a low-lying doubly excited state that is not energetically accessible for the monomer. This state delays the fluorescence allowing internal conversion to occur first. We characterize the doubly excited state wavefunction by systematically changing the derivatives to tune the pi-scaffold size and the acceptor and donor characters. The origin of this state's stabilization is related to the increase in the π-system and not to the charge-transfer features. This analysis delivers core conceptual information on the electronic properties of organic chromophores arranged symmetrically around a vinyl linker, opening new ways to control the balance between luminescence and internal conversion.

There are currently fewer than ten antifungal drugs in clinical development, but new fungal strains, which are resistant to most current antifungals are spreading rapidly across the world. To prevent a second resistance crisis, new classes of antifungal drugs are urgently needed. Metal complexes have proven to be promising candidates for novel antibiotics, but so far, few compounds have been explored for their potential application as antifungal agents. In this work we report the evaluation of 1039 metal-containing compounds that were screened by the Community for Open Antimicrobial Drug Discovery (CO-ADD). We show that 20.9% of all metal compounds tested have antimicrobial activity against two representative Candida and Cryptococcus strains, compared with only 1.1% of the >300,000 purely organic molecules tested through CO-ADD. We identified 90 metal compounds (8.7%) that show antifungal activity while not displaying any cytotoxicity against mammalian cell lines or haemolytic properties at similar concentrations. The structures of 21 metal complexes which display high antifungal activity (MIC ≤ 1.25 µM) are discussed and evaluated further against a broad panel of yeasts. Most of these have not been evaluated for antifungal activity. Eleven of these metal complexes were tested for toxicity in the Galleria mellonella moth larvae model, revealing that only one compound showed signs of toxicity at the highest injected concentration. Lastly, we demonstrated that the organo-Pt(II) cyclooctadiene complex Pt1 significantly reduces fungal load in an in vivo G. mellonella infection model. These findings showcase that the structural and chemical diversity of metal-based compounds can be an invaluable tool in the development of new drugs against infectious diseases.
Comparing the sensitivity of low- and high-resolution mass spectrometry for xenobiotic trace analysis: A exposome-type case study
Authors: Flasch Mira , Koellensperger Gunda , Warth Benedikt
Published: May 2022

The chemical exposome consists of all environmental exposures experienced throughout a lifetime. Liquid chromatography high-resolution mass spectrometry (HRMS) is common in untargeted exposome-wide analyses of xenobiotics in biological samples; however, human biomonitoring approaches usually utilize targeted low-resolution triple quadrupole (QQQ) mass spectrometry tailored to a small number of chemicals. HRMS can identify novel contaminants over a broad mass range but the detection of molecules from low-level exposure amidst a background of highly-abundant endogenous molecules has proven to be difficult. In this study, high- and low-resolution mass spectrometry with identical chromatography was utilized to determine the limits of quantitation (LOQ) of >100 xenobiotics and estrogenic hormones in pure solvent and human urine. For HRMS analyses, the median LOQ was 0.9 and 1.2 ng/mL in solvent and urine, respectively and for low-resolution QQQ measurements, the median LOQ was 0.1 and 0.2 ng/mL in solvent and urine, respectively. To evaluate the calculated LOQs in complex biological samples, spot urine samples from 24 Nigerian females were measured. The higher LOQ values for HRMS resulted in less quantified low-abundance analytes and decreased the number of compounds detected below the LOQ. Even at chronic low-dose exposure, such compounds might be relevant for human health because of a high individual toxicity or potential mixture effects. Nevertheless, HRMS enabled the additional screening for exposure to unexpected/unknown analytes, including emerging compounds and biotransformation products. Therefore, a synergy between high- and low-resolution mass spectrometry may currently be the best option to elucidate and quantify xenobiotics in exposome-wide association studies (ExWAS).

Herein, we demonstrate the superior performance of novel bismuth subcarbonate ((BiO)2CO3) film catalysts for formate production using a fluidic CO2-fed electrolyzer device. The subcarbonate catalyst readily forms in situ from a CO2-absorbing Bi2O3 precursor material during the CO2 reduction reaction (CO2RR). In 1 mol dm–3 KOH electrolyte solution, a maximum Faradaic efficiency of FEformate = 97.4% (corresponding partial current density of formate formation: PCDformate = –111.6 mA cm–2) was achieved at a comparably low applied electrolysis potential of –0.8 V versus the reversible hydrogen electrode (RHE). Even higher values of PCDformate = –441.2 mA cm–2 (FEformate = 62%) were observed at more cathodic potential, –2.5 V vs. RHE. As the alkalinity of the liquid electrolyte is further increased (e.g., by using 5 mol dm–3 KOH solution), the performance of formate production is boosted beyond PCDformate values of –1 A cm–2. Combined X-ray diffraction and Raman spectroscopic investigations demonstrate an extraordinarily high stability of Bi(III) cations in the catalytically active subcarbonate catalyst phase down to cathode potentials of –1.5 V vs. RHE. This stabilization effect can clearly be attributed to the high abundance of gaseous CO2 under the operating conditions of the gas-fed electrolyzer. In the absence of any CO2 supply, however, the reductive Bi(III)-to-Bi(0) transition already occurs at much milder conditions of –0.3 V vs. RHE, as evidenced by in situ Raman spectroscopy in CO2-free 1 mol dm–3 KOH electrolyte solution. Advanced X-ray diffraction computed tomography (XRD-CT) technique was applied to gain deeper insights into the spatial distribution of the metallic and subcarbonate phases comprising the active composite catalyst layer (CL) during the CO2RR.

Published: May 2022

Tujuan pelaksanaan pelatihan flourishing untuk membantu anggota organisasi meningkatkan self compassion. Mahasiswa memiliki kesempatan mengembangkan diri secara akademis dan secara sosial selama belajar di perguruan tinggi. Usia mahasiswa saat belajar di perguruan tinggi biasanya berada pada masa emerging adulthood. Salah satu karakteristiknya ialah identity exploration yang terdiri dari eksplorasi relasi romantis, eksplorasi pekerjaan dan eksplorasi cara pandang akan dunia. Salah satu cara mahasiswa melakukan eksplorasi pekerjaan dengan mengikuti organisasi. Anggota Organisasi Mahasiswa Universitas X Surabaya juga mengalami hal serupa. Saat masa kepengurusan, sedang terjadi pandemi Covid-19 dan mengharuskan seluruh pelaksanaan kegiatan secara daring. Hal ini menyebabkan persoalan self compassion karena anggota organisasi memilih pasif, mengisolasi diri dan mengkritik diri berlebihan ketika mengalami kesulitan. Metode penelitian menggunakan teknik penelitian quasi experimental, yaitu teknik penelitian dengan menggunakan desain one group pretest posttest design. Pelaksanaan pelatihan selama 2 hari dan 6 sesi melalui aplikasi Zoom Meeting. Hasil analisis uji beda wilcoxon (0.289; p<0.05) menunjukkan adanya perbedaan self compassion antara sebelum dan setelah pemberian pelatihan flourishing, namun perbedaan yang terjadi tidak signifikan. Hal yang menyebabkan kondisi ini ialah interaksi sosial belum berfungsi secara utuh di dalam organisasi dan adanya faktor tahap perkembangan pada usia mahasiswa, sehingga pelatihan flourishing tidak dapat meningkatkan self compassion secara signifikan.

Between the Global and Regional: Asia in the Tamil Buddhist Imagination
Authors: Narasimhan Shrinidhi
Published: May 2022

At the turn of the nineteenth century, Madras became home to a movement that anticipated Ambedkar’s turn to Buddhism by nearly half a century. Founded in 1898, the Sakya Buddhist Society was led by Iyothee Thass (1845–1914) and became the first Dalit Buddhist revival of its kind in late colonial India. In this article, I explore the global dimensions of Sakya Buddhism through an intertextual reading of its journal, Oru Paica Tamilan, and the work of Asian Buddhists like Henry Olcott and Anagarika Dharmapala who were associated with the movement. I argue that Sakya Buddhism’s historical imaginaire of Dalits as indigenous Buddhists intersected with the political concerns that drove Asian Buddhist revivalist movements in important ways. I also show that the movement created a distinctly Tamil tradition of Buddhism for Dalits and attempted to reorient them towards the broader Buddhist world even as they had a notionally marginal presence within this landscape. In doing so, I propose the category of ‘pararegional’ as a way of thinking about seemingly uneven or unidirectional interactions between different spatial scales such as ‘global’ and ‘regional'.
Maadathy-An Unfairy Tale: Caste, Space, and Gaze
Authors: Eswaran Swarnavel
Published: May 2022

This essay engages with Maadathy (dir. Leena Manimekalai, 2019) to explore how space is constructed as a marker of caste and interrogate the concomitant intersection of caste and gender in a divided community. Through the retooling of myth, Maadathy explores the horror at the heart of a patriarchal society that is invested in caste as a means of oppression, violence, and inequity. However, such a perverse agenda comes back to haunt the community, which is invested in destroying an adolescent girl without any concern for her desires and finally trying to deify her and find a way for the catharsis of their guilt. Untouchability runs as a subtext throughout Maadathy as Yosana and her family are marked, even more inhumanely and unjustly, as unseeable people, wherein the onus to be not seen falls on them. They are abused verbally and physically when they are going about their mundane chores. Nonetheless, the focus on the joyful demeanor of the pleasure-seeking Yosana through the Lacanian lens of the gaze initially enables the understanding of the yearning for subjective mastery from the other side of the village community whose men repeatedly target and try to contain her. However, Yosana’s gaze does not allow itself to be domesticated. The jouissance of Yosana, marking her singularity as the casteless adolescent girl, troubles those who want to contain and destroy her effervescence and, even after her death, continues to haunt them as they are blind to the impossibility of knowing the secret of her desire.

Assessment of inorganic nitrogen and phosphorus compounds removal efficiency from different types of wastewater using microalgae cultures
Authors: Nezbrytska Inna , Shamanskyi Sergii , Pavliukh Lesia , Kharchenko Galina
Published: May 2022

The efficiency of ammonium nitrogen (N-NH4 +) and phosphate (P-PO4 3-) removal from wastewater with different loads of these nutrients was evaluated using Chlamydomonas reinhardtii (Сhlоrорhуtа) and Oscillatoria neglecta (Суаnорhуtа/Cyanoprokaryota). In addition, functional characteristics of the microalgae under the studied conditions were determined. It was demonstrated that Ch. reinhardtii is resistant to a wide range of concentrations of inorganic nitrogen and phosphorus compounds. Microalgae actively participate in the removal of N-NH4 + from wastewater (removal efficiency of 49–63%, depending on the initial concentration). At the same time, Ch. reinhardtii showed low levels of P-PO4 3- removal (7–18%) from the aquatic environment. O. neglecta, unlike Ch. reinhardtii, is sensitive to excessively high concentrations of N-NH4 + (90–140 mg l−1) and P-PO4 3- (26–90 mg l−1). However, it is characterized by high removal efficiency for both forms of nitrogen (60–61%) and phosphorus (43–55%) at their initial concentrations of 30–50 mg l-1 and 7–14 mg l-1, respectively. Therefore, O. neglecta is best suited for use in wastewater post-treatment.
Prospects and opportunities for mussel Mytilus trossulus farming in the southern Baltic Sea (the Gulf of Gdańsk)
Authors: Sokołowski Adam , Lasota Rafał , Sami Alias Izabela , Piłczyńska Joanna , Wołowicz Maciej
Published: May 2022

In the Baltic Sea, where osmotic stress limits the growth of marine organisms, mariculture is driven primarily by the need to improve the status of the environment. To this end, several mussel farms have been attempted in selected areas, except the southern Baltic. The pilot culture of  Mytilus trossulus  was carried out with the use of a modified long-line system in the Gulf of Gdańsk in 2009–2012, providing the first evaluation of the mussel farming potential in this area. The growth rate of mussels (3.0–6.7 mm year-1) in the gulf was in the low range, but the mean wet biomass gain (1.50 kg m-1 normalized culture rope) was among the highest in the Baltic. After a two-year growth period, one tonne of mussels fixed in their soft tissues from 93 to 98 kg N t-1 and 11 kg P t-1. The cost-benefit analysis revealed a negative budget balance of production for human consumption, with a total income covering only 12.0% of the cumulative costs. Mussel farming in the gulf can therefore only be justified to improve the environmental quality if additional funding mechanisms are put in place to support farming activity.

Published: May 2022

As a major component of freshwater ecosystems, insect species play an important role in nutrient cycling and are often used as bioindicators of water pollution. Although extensive studies have characterized insects from freshwater habitats, little is known about the distribution of these species along the Lower Sector of the Danube River. Therefore, this survey conducted in the Danube section within the Romanian territory aimed to identify insect larvae belonging to seven different species of Odonata, Trichoptera, Ephemeroptera, Lepidoptera and Megaloptera by DNA barcoding and to investigate their distribution, density and frequency. A total of 41 quantitative macrozoobenthic samples were collected during two consecutive years (2019 and 2020). Species showed large differences in the distribution and density along different sections, and an overall tendency to populate downstream areas, except for Sialis morio. On the other hand, only Hydropsyche bulgaromanorum, Triaenodes bicolor and S. morio larvae were identified in the upstream section (Sulina branch). These data provide baseline information on the larger range of some of the most common aquatic insects in the Romanian Danube section in relation to several environmental parameters based on the first molecular identification of these species using COI gene sequencing.

It has been determined that 24% of the midwives has witnessed a faulty medical practice and 5.4% of midwives make medical errors. The most observed types of medical errors encountered by midwives; umbilical cord prolapses due to amniyotomy prematurely (42.7%), damage to the anal sphincter during episiotomy (62.7%) and forgetting foreign object after repair of episiotomy (32%).  At the end of the study has appeared should be giving importance to vocational training and postgraduate service training for reducing medical errors and protection from malpractice midwives.
Is Covid-19 responsible for asthma and COPD exacerbations?
Authors: Çilekar Şule , Balcı Aydın , Coşgun İbrahim Güven
Published: May 2022

COVID-19 is an infectious disease that is transmitted by the respiratory tract and was first identified in the Wuhan province of China. The causative agent of the disease is SARS-CoV-2. There is little known about this disease and its agent, which affected the whole world in a short time and became a pandemic. Molecular interactions between COVID-19 and chronic respiratory diseases are unknown. In this study, we examined the patients admitted to our outpatient clinic with the diagnosis of Asthma and Chronic Obstructive Pulmonary Disease (COPD) exacerbation. We investigated how much of the exacerbations during the pandemic period are caused by the COVID-19 virus and whether there have been any changes in the treatment of and approaches to exacerbations stemming from COVID-19. COVID-19 was detected in 135 of the patients. Clinically, fever, myalgia, and headache findings were significantly more common in patients with a positive COVID-19 PCR CoV 2 test in patients who were diagnosed with an attack of Asthma or exacerbation of COPD (p<0.001). The number of hospitalizations, the need for intensive care, the need for ventilation support, and the number of mortality were high in asthma and COPD patients with positiveSARS- CoV-2 tests (p<0.05 ). Based on the results of our study, patients with COPD and asthma exacerbations due to COVID-19 should be evaluated from a wider perspective. As is known, chronic diseases are poor prognostic factors for COVID-19, but asthma and COPD chronic disease are prominent among them. If there is a need for different approaches for the treatment of these patients, these approaches should be determined urgently.
A qualitative research on the acculturation strategies, risk factors and health perceptions of Syrian asylum seekers
Authors: Nural Arslan Dilek , Dağhan Şafak
Published: May 2022

The internal turmoil, that broke out in Syria, started a mass migration movement towards Turkey in 2011. This migration movement, which proved to be an important social phenomenon, individuals from many different cultures have experienced coexistence for compulsory reasons. On top of that experience they were subjected to, the addition of a highly complicated process of acculturation, and the risk factors which immigrants and ethnic minority groups faced caused them to classify as vulnurable regarding health. The aim of this study is to assess how the preferred acculturation strategy of Syrian asylum seekers, who found themselves living along with different cultures, their negative or positive experiences and the risk factors they face affects their health, and health perceptions. The research was designed as a phenomenological research. In-depth interviews were conducted with 24 participants, who were included in the study, using the purposive sampling strategies, homogeneous case sampling and criterion sampling technique. In addition to the usage of code book obtained from the literary works related to the field using the deductive method, the data recorded by observing and the notes from interviews were reduced to themes, categories and codes using the inductive method. The study is grouped under three main themes, namely acculturation strategy of Syrian asylum seekers, risk factors affecting the healths of Syrian asylum seekers and health perception of Syrian asylum seekers. Statistical analysis of the data was carried out by using descriptive analysis and content analysis provided in the MAXQDA 2020 pro-package program. Although the participants heavily express their opinions in favor of seperationg strategy, which is one of the acculturation strategies, this is followed by an integration strategy. Furthermore, the participants were observed to have been subjected to discrimination and rejection, and in this process, facing risk factors mainly social, psychological, environmental, physical and barriers affecting healthcare procurement. Multiple relational analysis show that an intense relationship was found between the participants who preferred the separatist strategy and the risk factors affecting their health. It was observed that the participants who reported good health perception before migrating; due to the most reported social risk factor, economic barriers, reported negative health perception after migrating. The majority of participants who preferred the integration strategy reported good health perception both before and after migration.
Assessment of plasma lipid parameters, exhaled nitric oxide fraction, and systemic immune-inflammation index on stable asthma patients
Authors: Düz Muhammed Emin , Balcı Aydın
Published: May 2022

Asthma is a chronic disease characterized by the presence of inflammatory agents in the airways, and diagnosis and treatment are based on clinical questioning, physical examination, laboratory results, and spirometric analysis. This study investigated the effect of asthma alone on routine laboratory parameters in adults and whether an idea about the course of the disease can be obtained using these parameters. Two hundred and fourteen patients with known asthma history, diagnosed, and treated according to guidelines, were included in our study. Among all patients and between gender-specific groups, total cholesterol (CHOL), HDL, LDL, VLDL, triglyceride (TG), albumin, total protein (TP), lactate dehydrogenase (LDH), glucose, urea, creatinine, C reactive protein (CRP), FeNO, SII, INR, and complete blood count value parameters of the patients were analyzed. When we consider all asthma patients, we found that the mean glucose, LDH, CRP, TG, FeNO, and INR values outpaced the upper limit of the reference range. In contrast, the mean HDL value was below the reference range for all patients. In addition, our study found a significant correlation between triglyceride levels within the biochemical parameters with FeNO and SII). Finally, when we compared the mean values of gender-specific groups, we found a statistically significant difference between VLDL, HDL, TG, CRP, FeNO, creatinine, lymphocyte, eosinophile, basophile, and hemoglobin. CRP, LDH, TG, FeNO, SII, and INR levels may help clinicians in adult patients with stable asthma. In addition, differences depending on gender could be observed in the biochemical parameters of asthma patients.
