Authors: Souza Larissa Fatima de , Demarchi Carla Albertina , Rodrigues Clovis Antonio
Published: August 2022

Os antibióticos são substâncias classificadas como contaminantes emergentes e são uma preocupação constante devido aos efeitos deletério, ao meio ambiente e ao ser humano, principalmente pelo desenvolvimento de microrganismos resistentes aos antibióticos. A tecnologia atual de tratamento de águas residuais não pode remover antibióticos de esgoto de maneira eficiente e, portanto, novas tecnologias de baixo custo são necessárias. Neste trabalho, foi utilizado um material carbonáceo, preparado com fezes de cupim quimicamente ativado, como adsorvente de baixo custo, para remoção do antibiotico norfloxacina (NOR) presente em meio aquoso. As fezes de cupins foram tratadas com Na2CO3 H3PO4 e NaOH, 1 M, 24 h e 100 ° C para ativação química e depois lavadas com água destilada. Os experimentos forma feitos em sistema de batelada, para estudar a influência do tipo de adsorvente, pH, tempo de contato, temperatura e concentração inicial de NOR. Para o estudo de sorção, vários parâmetros foram otimizados (pH, temperatura, tempo de contato) e os dados foram ajustados às isotermas de Langmuir, Freundlich e Sips para demonstrar o mecanismo de sorção. Os dados cinéticos foram analisados ​​por equações de pseudo-primeira ordem e pseudo-segunda ordem. Os adsorventes têm uma área de superfície específica entre 61 e 2433 m2/g e um ponto de carga zero entre 7,4 e 10,1, dependendo do agente ativante. O melhor ajuste para as isotermas Sips sugeriu um modelo de adsorção do tipo monocamada, e a capacidade máxima de adsorção do adsorvente foi de 111 mg/g para o adsorvente preparado com fezes de cupim ativada com H3PO4 (TFPO4) e 169 mg/g para o para o adsorvente preparado com fezes de cupim ativada com NaOH (TFOH). Os resultados indicam que o modelo de pseudo-segunda ordem explica a cinética de adsorção de forma mais eficaz, com r2 na faixa de 0,961 e 999. Os resultados apresentados neste trabalho mostraram que o que os materiais carbonáceos, quimicamente ativados, como adsorventes de baixo custo, para a remoção da norfloxacina presente em sistemas aquosos.

Authors: PANKOVA Svetlana V. , KUZ'MICHEVA Aleksandra V.
Published: August 2022

Subject. Effective internal control system helps achieve sustainable development goals of Russian corporations. The introduction of integrated reporting into the practice of companies enables to obtain information about available units performing control functions, types and forms of control they use. In the study, we consider the case of companies of the energy industry that prepare and publish integrated reporting.
Objectives. The aim is to develop analytical tools to identify the effectiveness of internal control and audit services, and how they fit the scale of enterprises.
Methods. The study draws on general scientific methods of logical analysis, comparison, and the mean-value method.
Results. Based on the analysis of publicly available integrated reporting of Russian energy companies, we unveil shortcomings in the organization of internal and external control, when confirming the reliability of published reports, find the dependence of types of control services on the scale of the enterprise, and reveal their indirect impact on return on assets.
Conclusions. To increase the confidence of potential investors, it is recommended that CEOs evaluate reliability and validity of financial and non-financial information. When creating internal control and audit units, it is necessary to focus on the size of company's assets to avoid inefficient increase in the number of control units, duplication of their functions, and distraction of performers from achieving the goals of the organization.

Authors: GAVRYUSHENKO Anna P.
Published: August 2022

Subject. The article addresses the institutional environment in which the Russian financial control is organized and operates.
Objectives. The aim is to unveil problematic areas of organization of financial control and develop proposals for their elimination, from the standpoint of institutional approach.
Methods. The validity, reliability, and relevance of proposals rest on a set of approaches, in combination with general scientific and special methods of scientific cognition, like retrospective, systemic, functional-structural analysis, observation, classification, instrumental methods of grouping, sampling, comparison, and generalization, as well as evolutionary and dynamic analysis.
Results. On the basis of traditional domestic centralized and modern dispersed models of financial control, the paper identifies the possibility of combining their advantages. This enables to ensure interconnection and coordination within the framework of improved model of State financial control. I propose to mutually recognize the results of financial control bodies, including intra-departmental control. Thus, the institutional State financial control will get a "vertical", the competence of which will include all institutions and organizations using budgetary funds. The purpose of the improved control system functioning will expand and go beyond the identification of compliance with the parameters of financial management in the controlled areas.
Conclusions. The institutional approach will enable to solve management problems, strengthening the resource-saving control function.
Where the Trees Stood in Water

Published: August 2022

Where the Trees Stood in Water is a series of Cyanotype prints tracing the historic and contemporary transformations of Toronto’s Entertainment District. Each print is accompanied by an archival document which forms a narrative connecting geography to stories of colonization, industrialization and the transient bodies of those affected by the remaking of Toronto’s landscape. Juxtaposing text and image, Where the Trees… pushes against the archival documentation of Toronto’s past and challenges the stories told about colonialism, labour and migration. With playful reproductions, Bambitchell invites hidden, obscured, lost, and silenced narratives of colonial history to surface and tell new stories about the geography of Toronto’s core.

Re-membering a Queer Body
Authors: Holmes Morgan
Published: August 2022

In the spring 1993 issue of The Sciences, Brown University geneticist Anne Fausto-Sterling, citing the work of John Money, indicates that approximately four percent of the population is, to some degree, intersexual: they either possess physical characteristics of both officially recognized sexes or they have chromosomes which indicate a sex which are 'contradicted' by their physical appearance.1 In Toronto, the four percent figure translates into roughly 88,000 people. Yet little has been written about intersexuality, although its concerns often intersect with those of feminist and queer theory. This paper deals with feminist issues in patriarchal medicine and its relation(s) to intersexuality (and intersexuality's inherent ability to challenge arguments for the 'natural' basis of heterosexuality).

Queer Theory for Lichens
Authors: Griffiths David
Published: August 2022

An article published in The Quarterly Review of Biology in December 2012 ended with the sentence: “We are all lichens.” The article discusses symbiosis in organisms such as lichens as well as in humans, to argue that humans cannot be thought of as individuals by any biological criteria. In this article I follow this argument and offer a brief naturalcultural history of lichens to illustrate their argument and the work of biologist Lynn Margulis on symbiogenesis. Following this, I ask: if we have never been human – if we are all composites like lichens – then what does this mean for sexuality? I argue that lichens and other symbioses can open up a queer ecological perspective that can help counter the privileging of heteronormativity and sexual reproduction, and that this has consequences for both science and society.

Dark Ecology and Queer, Amphibious Vampires
Authors: Booth Naomi
Published: August 2022

This paper argues that early vampire narratives can be reread as queer ecological fictions, darkly re-imagining the human as a liminal, amphibious entity. I highlight the importance of the amphibian—a slippery, ambiguous creature—to contemporary eco-deconstructive accounts that seek to disrupt and queer species categorizations, focusing in particular on Timothy Morton’s notion of “dark ecology” (2007). Early vampire literature, I argue, similarly deconstructs the distinction between different species through its erotic depictions of enmeshed ecologies. Analyzing the new blood-relations established in Bram Stoker’s Dracula (1897) and the figure of the queer female vampire described as “amphibious” in Sheridan Le Fanu’s Carmilla (1872), I suggest that vampire narratives depict dark new ecologies, establishing an “in-betweeness” shared by the living and the undead. The final part of this paper considers the importance of loss to current theorizations of queer ecology: Catriona Mortimer-Sandilands (2010) has recently advocated a state of suspended mourning for what has been destroyed by anthropocentric and homophobic violence. I posit the haunting figure of the vampire as one example of literature’s “non-normalizing relationship to the past” (Mortimer-Sandilands)—a relation of return that might form an important part of queer, ecological resistance to current practices of unmarked destruction.

La Búsqueda de Visión como potenciadora de resiliencia en situaciones de aislamiento e incertidumbre
Authors: Mendoza Verónica Trujillo , Morón Carlos Edwin
Published: August 2022

Una de las iniciativas para la contención de la pandemia fue el confinamiento. En su atención, la OMS recomendó el contacto virtual para mitigar la tristeza y estrés. La población relacionada con la cosmovisión de comunidades originarias resolvió esta cuestión a través del ritual Búsqueda de Visión. Por tanto, interesa describir de qué manera la participación en esta práctica influyó para asumir el confinamiento, así como los procesos anímicos derivados. Tal preocupación busca reconocer de qué manera un ritual permite establecer procesos para asumir el miedo y la depresión. La prenoción desde la que se intenta responder implica que los Buscadores, han encontrado maneras integrales de transitar el confinamiento, derivadas del proceso voluntario de aislamiento. Esta condición resiliente se presenta debido a que la experiencia vivida en el ritual permite un espectro de tolerancia más amplio a circunstancias emergentes. En esta exploración se recuperan algunos aportes críticos sobre la condición emotiva del ser humano en la actualidad, así como la importancia que tiene la pérdida de la conducta ritual en ello.

One of the initiatives to contain the Sars-Cov-2 was the lockdown. The OMS recommended the virtual interaction to prevent sadness and stress. Some indigenous people solved this issue through his participation in a Vision Quest ritual. The central issue of this reflection to describe how the practice of this ritual influenced to face the lockdown, and the emotional processes of the people. This essay seeks to know how the ritual allows to assume the fear and depression. The proposal for those question is: the vision questers has found integral ways to confront the lockdown because the voluntary processes of isolation. The vision quest helps the people to be resilient because the voluntary isolation gives them abilities to face emergent situations. For this paper we use some critic concepts of emotional condition of human being and the importance of the loss of ritual behavior proposed by Byung-Chul Han.

Authors: Normanyo Erwin , Blewushie Philip , Atatsi Cyril Yao
Published: August 2022

The challenge of regularly charging the battery of cellular phones has brought about new and more convenient ways to realising cellular battery charging. The wireless power platform has been explored for years bringing about many dimensions to its realisation. In this research, developed a wireless charging of  Li-Ion battery of a cellular phone using commercial-off-the-shelf components vis-a-vis Radio Frequency (RF) energy. A MAX2623 voltage controlled oscillator was used to generate RF signals at a frequency of 915 MHz. Through a series of amplifier stages, the signal is radiated using a half-wave dipole antenna. The signal is received by a remote receiver module made up of 5 dBi gain half-wave dipole antenna which is impedance matched to a bridge rectifier made of SMS3929 Bridge Quad Schottky low turn-on voltage diodes. The rectified output is received by a EH4205 low voltage booster which amplifies the input into two paralleled MAX 682 charge pumps. The paralleled MAX 682 charge pump delivers a constant output voltage of 5 V DC and current of 500 mA. Within a 4 m radius the receiver module can receive enough power for the realisation of wireless battery charging.

Performance Assessment of Shirin Earth Dam in Iraq Under Various Operational Conditions
Authors: Zedan Adnan Jayed , Faris Marewan Ridha , Bdaiwi Ali Kareem
Published: August 2022

Proper dam management should be ensured regularly to avoid breaches and failure. In this study, the finite element method was used to analyse the stability of the Shirin earthen dam under various conditions. The necessary laboratory tests for soils used in the construction of the dam were carried out in the laboratories of the College of the Engineering /University of Tikrit, and these data were employed in the GEO-STUDIO program to analyse the seepage and stability of the dam. The seepage was analysed at three levels of the water lake reservoir including the highest, middle and lowest water levels. In addition, factors such as the permeability of the shell layer, the presence and thickness of the dam’s core layer, the placement of filters at the back of the dam and the exit gradient have been considered. The results have shown that by increasing the permeability of the shell layer, the exit gradient is decreased while the seepage through the dam body is increased. The presence of the dam’s core layer has a significant effect on reducing the amount of seepage through the dam’s body as the amount of seepage is reduced by (99%). Moreover, it was found that the minimum safety factor is 1.95 and it occurs after (4 days) of the rapid emptying of the reservoir, and this indicates that the upstream slope of the dams is safe during water emptying.
Analysis of Transition to Thermo-Acoustic Instability in Swirl Combustor Using Variational Auto-Encoders
Authors: Ramanan Vikram , Ramankutty Anusai , Sreedeep Sharan , Chakravarthy Satyanarayanan R.
Published: August 2022

The prognosis of thermo-acoustic/combustion instability is usually accomplished by applying a priori knowledge about features of unstable operation and measuring deviation from those features using point values. In the present work, we adopt a different methodology, whereby the presence and extent of the signature of unstable combustion are learnt as an anomaly from the distribution of pressure oscillations during stable operation across several protocols. The protocols involve a transition from stable to unstable operation in a swirl combustor. It is inferred that the stable combustion in the present case is stochastic noise with a normal distribution containing values comparable with root-mean-square values at unstable operation with a [Formula: see text] value 0.05–0.07. We exploit this feature to detect anomalies from flame intensity images, which represents the heat release rate fluctuations by manipulating their features to be a part of multivariate Gaussian distribution. To formulate this distribution, we employ a convolutional-neural-network-based variational auto-encoder (CNN-VAE) and express the associated reconstruction loss as an anomaly metric. The anomalies obtained through CNN-VAE and integrated intensity fluctuations are then evaluated for their sensitivity against the unsteady pressure data. The analysis reveals that the CNN-VAE metric performs better than the integrated intensity fluctuations for predominantly all [Formula: see text] values.

To increase the income of rice farmers in Sukabumi City, the Sukabumi City Food Security, Agriculture and Fisheries Service made a new breakthrough, namely the One Roof program which began in 2020. This program was implemented as a farmer partner institution, in this program an offtaker was appointed who in terms of guarantees financing capital for farming and at the same time guaranteeing the market for agricultural products. Farmers will obtain a business financing loan facility from the offtaker with a guarantee that the resulting product is sold to the offtaker at a reasonable price. The existence of offtakers is expected to be able to reduce farmers' dependence on middlemen who generally harm farmers. In addition, there is assistance from sapras (fertilizers and pesticides) to alleviate the need for sapras whose prices are increasing. The purpose of this study was to analyze the differences in production costs, production and income of lowland rice farmers before and after participating in the One Roof program. The data analysis method used was unpaired t-test. The results of the analysis show that the cost of farming production before participating in the One Roof Program is Rp 8,178,302/Ha, and after Rp 7.723.236, this shows a significant difference. Rice production before joining the One Roof Program was 6,530 Kg/Ha, and after 6,542 Kg/Ha, showed no significant difference. For lowland rice farmers' income before and after participating in the One Roof program, it shows a significant difference, before Rp 17,941,762/Ha/MT, while after Rp 20,408,759/Ha/MT.

Кундравы и других населенных пунктах Чебаркульского района Челябинской области. В контексте исследований региональных и локальных особенностей обрядовой культуры материалы, собранные И. Тимофеевым, представляют научный интерес. Необходимо отметить, что Чебаркульский район является крайне малоизученным в области фольклора и этнографии, что, безусловно, определяет актуальность данной темы. В статье представлена структура приложения рукописи, характеристика его разделов, проводится краткий анализ экспедиционных материалов, выявляются основные особенности свадебного обряда Чебаркульского района. Собранные И. И. Тимофеевым экспедиционные фольклорно-этнографические материалы по Чебаркульскому району восполняют один из неисследованных сегментов традиционной свадебной обрядовой культуры Южного Урала.

This article discusses the materials from the appendix of a manuscript of Igor Ivanovich Timofeev, collector and scholar of the Russian wedding ritual. In the period from 1993 to 1999, he collected historical and folklore-ethnographic materials on the structure and vocabulary of the wedding ceremony in the village of Kundravy and other settlements of the Chebarkul district of the Chelyabinsk region. The materials Timofeev collected are of special scholarly interest in the context of the study of the regional and local peculiarities of ritual culture. The folklore and ethnography of the Chebarkul district is poorly studied, which makes his work especially valuable. The article describes the structure of his manuscript’s appendix and its sections, giving a brief analysis of the expedition materials and presenting the main characteristics of the Chebarkul district wedding ceremony. The folkloric and ethnographic materials concerning the wedding ceremony that Timofeev collected on expeditions in the Chebarkul district help fill the gap in our knowledge of the ritual culture of the Southern Urals.

Colorimetric Monitoring of a Chemical Reaction Using Cesium Lead Iodide Assays
Authors: Doane Tennyson L. , Cruz-Lopez Kevin J. , Maye Mathew M.
Published: August 2022

In this work we take advantage of halide exchange (HE) at cesium lead iodide (CsPbI3) nanoparticles to develop an assay that is sensitive to bromide ions (Br-) released during an organohalide reaction. Upon sampling the reaction, the free Br- react quickly with the CsPbI3, resulting in CsPbBrxI3-x intermediates, each of which have unique blue-shifted photoluminescence (PL) wavelengths, the change of which (), we use as a colorimetric proxy of the reaction. An assay response factor, C, relates  as a function of CsPbI3 concentration, as well as Br- concentration. The observed kinetics, as well as calculated rate constants, equilibrium, and activation energy of the solvolysis reaction tested correspond closely to synthetic literature values, validating the assay. Factors that influence the sensitivity and performance of the assay, such as CsPbI3 size and morphology, and concentration, are discussed.

Chemical products, such as plastics, solvents, and fertilizers, are essential for supporting modern lifestyles. Yet, producing, using and disposing of chemicals creates adverse environmental impacts which threaten the industry's license to operate. This study presents seven planet compatible pathways towards 2050 employing demand-side and supply-side interventions with total investment costs of US$1.2-3.7 billion. Resource efficiency and circularity interventions reduce global chemicals demand by 23–33% and are critical for mitigating risks associated with using fossil feedstocks and carbon capture and sequestration, and constraints on available biogenic and recyclate feedstocks. Replacing fossil feedstocks with biogenic/air-capture sources, shifting carbon destinations from atmosphere to ground, and electrifying/decarbonizing energy supply for production technologies, could enable net negative emissions of 200 MtCO2eq yr-1, while still delivering essential chemical-based services to society.

Published: August 2022

We report the evaluation of density-functional-theory (DFT) based procedures for predicting 19F NMR chemical shifts at modest computational cost for a range of molecules with fluorine bonds, to be used as a tool for assisting the characterisation of reaction intermediates and products and as an aid to identifying mechanistic pathways. The results for a balanced learning set of molecules were then checked using two further testing sets, resulting in the recommendation of the ωB97XD/aug-cc-pvdz DFT method and basis set as having the best combination of accuracy and computational time, with a RMS error of 3.57 ppm. Cationic molecules calculated without counter-anion showed normal errors, whilst anionic molecules showed larger errors, possibly due to omission of the counter-cation. The method was applied to the prediction of the conformationally averaged 19F chemical shifts of 2,2,3,3,4,4,5,5-octafluoropentan-1-ol, in which gauche stereoelectronic effects involving fluorine dominate and to determining the position of coordination equilibria of fluorinated boranes as an aid to verifying the relative energies of intermediate species involved in catalytic amidation reactions involving boron catalysts.
Copper-Catalyzed Alkynylation of Hydrazides: An Easy Access to Functionalized Azadipeptides
Authors: Le Du Eliott , Borrel Julien , Waser Jerome
Published: August 2022

We report a copper-catalyzed alkynylation of azadipeptides using ethynylbenziodoxolone (EBX) reagents. Non-symmetrical ynehydrazides could be obtained in 25-97% yield using azaglycine derivatives as nucleophiles. The transfor-mation is compatible with most functional groups naturally occurring on amino acid side-chains and allows the transfer of silyl-, alkyl- and aryl-substituted alkynes. The obtained α-alkynyl azaglycine products could be further functionalized by nucleophilic attack or cycloaddition on the triple bond.
Synthetic duocarmycins: structural evolution from SAR to prodrugs and ADCs - a searchable structure/function database
Authors: Felber Jan , Thorn-Seshold Oliver
Published: August 2022

Synthetic analogues of the DNA-alkylating cytotoxins of the duocarmycin class have been extensively investigated in the past 40 years, driven by their high potency, their unusual mechanism of bioactivity, and the beautiful modularity of their structure-activity relationship (SAR). This minireview analyses how the molecular designs of synthetic duocarmycins have evolved: from (1) early SAR studies, through to modern applications for directed cancer therapy as (2) prodrugs and (3) antibody-drug conjugates in late-stage clinical development. Analysing 583 primary research articles and patents from 1978-2022, we distill out a searchable A0-format "Minard map" poster of ca. 200 key structure/function-tuning steps tracing chemical developments across these three key areas. This structure-based overview showcases the ingenious approaches to tune and target bioactivity, that continue to drive development of the elegant and powerful duocarmycin platform.

Synthetic ionophores able to transport bicarbonate and chloride anions across lipid bilayers are appealing for their wide range of potential biological applications. We have studied the bicarbonate and chloride transport by carbazoles with two amido/thioamido groups using a bicarbonate-sensitive europium(III) probe in liposomes and found a highly remarkable concentration dependence. This can be explained by a combination of two distinct transport mechanisms: HCO3−/Cl− exchange and a combination of unassisted CO2 diffusion and HCl transport, of which the respective contributions were quantified. The compounds studied were found to be highly potent HCl transporters. Based on the mechanistic insights on anion transport, we have tested the antimicrobial activity of these compounds and found good correlation with their ion transport properties and a high activity against Gram-positive bacteria.
Stacked 3D Antiaromaticity in the π-Congested Space Between the Aromatic Rings in the Anthracene Dimer

Published: August 2022

Substance containing two π-congested aromatic systems are attractive targets in synthetic studies as well as efforts designed to explore the unique properties that originate from π-congestion. Since the time of the computational studies by Schleyer and Warner, the concept of stacked 3D aromaticity created by the encounter of two antiaromatic rings has received much attention. In contrast, questions about what happens when two aromatic rings are closely stacked have remained unanswered. To the best of our knowledge, only one computational study has been performed by Herges, the results of which suggest that [2.2]paracyclophane, possessing short distance (<3.00 Å) between two aromatic ring planes, has a paratropic ring current between two the benzene rings. This observation is consistent with the conclusion that stacked 3D antiaromaticity exists within the π-congested space between aromatic rings. Herein, we investigated the 3D antiaromaticity of highly π-congested anthracene dimers using anthracenophane, which possesses a short inter-plane carbon-carbon distance of ca. 2.80 Å. The absorption spectrum of this substance contains a weak broad band from 450 to 550 nm that is attributed from HOMO-LUMO transition. These properties exist in planar cyclooctatetraene derivatives that having 8π-electron antiaromaticity. The results of nucleus-independent chemical shift and anisotropy of the induced current density calculations indicate that relatively weak antiaromatic character exists between the central six-membered rings of the two anthracene moieties in anthracenophane. In addition, an attempt to enhance the stacked 3D antiaromaticity of anthracenophane using pressure to enhance π-congestion using was unsuccessful.
Assessment of the generalization abilities of machine-learning scoring functions for structure-based virtual screening
Authors: Zhu Hui , Yang Jincai , Huang Niu
Published: August 2022

In structure-based virtual screening (SBVS), it is critical that scoring functions capture protein-ligand atomic interactions. By focusing on the local domains of ligand binding pockets, a standardized pocket Pfam-based clustering (Pfam-cluster) approach was developed to assess the cross-target generalization ability of machine-learning scoring functions (MLSFs). Subsequently, 11 typical MLSFs were evaluated using random cross-validation (Random-CV), protein sequence similarity-based cross-validation (Seq-CV), and pocket Pfam-based cross-validation (Pfam-CV) methods. Surprisingly, all of the tested models showed decreased performances from Random-CV to Seq-CV to Pfam-CV experiments, not showing satisfactory generalization capacity. Our interpretable analysis suggested that the predictions on novel targets by MLSFs were dependent on buried solvent-accessible surface area (SASA)-related features of complex structures, with larger predicted binding affinities on complexes owning larger protein-ligand interfaces. By combining buried SASA-related features with target-specific patterns that were only shared among structurally similar compounds in the same cluster, random forest (RF)-Score attained a good performance in Random-CV test. Based on these findings, we strongly advise to assess the generalization ability of MLSFs with Pfam-cluster approach and to be cautious with the features learned by MLSFs.

Published: August 2022

Herein, we report the aggregation properties of metabolites of urea cycle and uric acid pathway. The aggregation/ self-assembly properties of these metabolites were studied extensively via microscopic techniques. In this context the self-assembling properties of citrulline, ornithine, xanthine, hypoxanthine, cytosine and uracil were studied by assessing its aggregation under varying ageing time from fresh to day 15 of incubation. Interestingly, the metabolites exhibited tendency to aggregate and form soft fibril assembly during the course of ageing and gradually changes to crystalline structures on prolonged incubation. The results presented in this manuscript may have important implications in the pathogenesis of diseasescause urea and uric acid pathway metabolic dysfunction like HHH syndrome, Citrullinemia, Xanthinuria, Lesh Nyahn syndrome and Gout caused by accumulation of these metabolites.
