Optimization and design of a new column sequencing for crude oil distillation at Basrah refinery
Authors: Hussain Muntadher Sallah , Fares Mohammad N. , Taher Mohammad A.
Published: March 2024

The utilization of distillation stands as a predominant separation method within the chemical and petroleum industries, prominently influencing operational costs and environmental impact due to energy consumption. Enhancing energy efficiency holds paramount significance in elevating the sustainability and overall efficacy of distillation operations. Within this study, we introduce an innovative approach termed “marginal vapor flow (MVF)” to optimize the distillation column sequence for crude oil processing, focusing on the third distillation unit at the Basra Refinery. This research evaluates diverse column designs through streamlined simulations using Aspen HYSYS V11 software. The study determines total energy consumption as a benchmark, comparing it against the optimal sequence recommended by the MVF methodology. A novel application of the downward reduction equation to crude oil guides the selection of light and heavy components. Key findings from this comprehensive analysis showcase the potency of combining MVF with Aspen HYSYS for optimizing crude oil distillation column sequences. Aspen HYSYS, a widely recognized process simulation tool, accurately represents distillation processes. Simultaneously, MVF facilitates the determination of optimal column sequences based on marginal vapor flow rates. Notably, the results reveal that within the studied sequences, sequence 9 exhibits the lowest total MVF of (1393.4 kmol/h), signifying its optimality, while sequence 2 displays the highest total MVF of (4827.3 kmol/h), representing the least favorable scenario. Simulation of the optimal sequence derived through the MVF approach exhibits a remarkable 35% reduction in energy consumption compared to real-life operations. Conversely, simulating the least favorable sequence demonstrates a substantial 32% increase in energy consumption compared to actual operations. This study underscores the pivotal role of MVF methodology in optimizing distillation sequences for enhanced energy efficiency, providing actionable insights for refining operations to significantly reduce energy consumption and operational costs while advancing sustainability goals.

Published: March 2024

The design of steel beam-column end-plate bolted connections is becoming increasingly popular owing to its simplicity of production. This requires knowledge of the full nonlinear resisting moment–rotation (M–Φ) behavior of the joint. To investigate the impact of various geometrical factors on the overall behavior of the connection, this work provides a three-dimensional finite element model (FEM) utilizing ABAQUS software. The suggested model accounts for the pretension force on the bolts, material and geometrical deviations from linearity, and the proximity of surfaces that are adjacent. The numerical model’s ability to simulate and process both the total and specific behavior of varieties of end-plate steel riveted connections is confirmed by calibrating the finite element findings with experimentally disclosed outcomes, which are reviewed in this study. The ultimate behavior was then investigated through a parametric study using the verified FEM with variations in the bolt pretension load, yield strength of the sections, and yield stress of the bolt considering the M–Φ curve. The results of the parametric study showed that as the bolt pretension load and yield stress of the column, beam, and plate materials increased, so did the connection’s moment ability. The yield tension of the bolts, however, had only a minor effect on the connection’s moment capacity.

Photothermal therapy (PTT) of nanomaterials is an emerging novel therapeutic strategy for breast cancer. However, there exists an urgent need for appropriate strategies to enhance the antitumor efficacy of PTT and minimize damage to surrounding normal tissues. Piezo1 might be a promising novel photothermal therapeutic target for breast cancer. This study aims to explore the potential role of Piezo1 activation in the hyperthermia therapy of breast cancer cells and investigate the underlying mechanisms. Results showed that the specific agonist of Piezo1 ion channel (Yoda1) aggravated the cell death of breast cancer cells triggered by heat stress in vitro. Reactive oxygen species (ROS) production was significantly increased following heat stress, and Yoda1 exacerbated the rise in ROS release. GSK2795039, an inhibitor of NADPH oxidase 2 (NOX2), reversed the Yoda1-mediated aggravation of cellular injury and ROS generation after heat stress. The in vivo experiments demonstrate the well photothermal conversion efficiency of TiCN under the 1,064 nm laser irradiation, and Yoda1 increases the sensitivity of breast tumors to PTT in the presence of TiCN. Our study reveals that Piezo1 activation might serve as a photothermal sensitizer for PTT, which may develop as a promising therapeutic strategy for breast cancer.

Authors: Korku Mihriban , Feyzullahoğlu Erol
Published: March 2024

The use of composite materials, which are more economical and have better material properties, has become widespread in the industry lately. The glass fiber reinforced polyester composite materials constitute majority of composite materials produced in industry. Wear reduces working life of machine parts, affects their functions, and causes undesired deterioration, resulting in part separation over the contact surface. The machine parts produced from glass fiber reinforced polyester composite materials wear out because of exposure to dry friction and fluid film lubrication under different operating conditions. In this study, wear behaviours of glass fiber reinforced polyester composite materials under dry friction and fluid film lubrication conditions were investigated. The various results were obtained with this study. The wear resistances of samples in dry friction and fluid film lubrication conditions are like each other. The use of glass fiber, glass bead and plasticizer tensile additive in glass fiber reinforced polyester composite specimens is effective in improving the wear resistance of specimens.

Published: March 2024

The construction sector has been under growing public attention recently as one of the leading causes of climate change and its detrimental effects on local communities. In this regard, geopolymer concrete (GPC) has been proposed as a replacement for conventional concrete. Predicting the concrete’s strength before pouring is, therefore, quite useful. The mechanical strength of slag and corncob ash (SCA–GPC), a GPC made from slag and corncob ash, was predicted utilizing multi-expression programming (MEP). Modeling parameters’ relative importance was determined using sensitivity analysis. When estimating the compressive, flexural, and split tensile strengths of SCA–GPC with MEP, 0.95, 0.93, and 0.92 R
2-values were noted between the target and predicted results. The developed models were validated using statistical tests for error and efficiency. The sensitivity analysis revealed that within the mix proportions, the slag quantity (65%), curing age (25%), and fine aggregate (3.30%) quantity significantly influenced the mechanical strength of SCA–GPC. The MEP models result in distinct empirical equations for the strength characteristics of SCA–GPC, unlike Python-based models, which might aid industry and researchers worldwide in determining optimal mix design proportions, thus eliminating unneeded test repetitions in the laboratory.

Nowadays, over 200 countries face a wellbeing emergency because of epidemiological disease COVID-19 caused by the SARS-CoV-2 virus. It will cause a very high effect on the world economy and the worldwide health sector. The present work is an investigation of the newly synthesized (Z)-2,6-bis(4-bromophenyl)-3,3-dimethyl-4-(2-(2,4,6-trichlorophenyl) hydrazono) piperidine (BBDTHP) molecule inhibitory potential against important protein targets of SARS-CoV-2 using computational approaches. For the title compound BBDTHP, spectroscopic characterization like FT-IR, 1H-NMR, 13C-NMR, 1H–1H COSY and 1H–13C COSY spectrum were carried out. The geometry of the compound had been optimized by the DFT method and its results were compared with the X-ray diffraction data. The calculated energies for the Highest occupied molecular orbital (HOMO) and the Lowest unoccupied molecular orbital (LUMO) showed the stability and reactivity of the title compound. The molecular electrostatic potential (MEP) picture was drawn using the same level of theory to visualize the chemical reactivity and charge distribution on the molecule. Molecular docking study performed for the synthesized compound revealed an efficient interaction with the COVID-19 protease and resulted in good activities. We hope the present study would help workers in the field to develop potential vaccines and therapeutics against the novel coronavirus. Virtual ADME studies were carried out as well and a relationship between biological, electronic and physicochemical qualifications of the target compound was determined. Toxicity prediction by computational technique for the title compound was also carried out. From the molecular dynamic simulations study, we confirmed hydrogen bonding interactions and stability of the molecule.

Published: March 2024

The widespread significance of tobacco in Mesoamerica is documented in historical and ethnographic sources, yet recovery of the organic remains of this plant from archaeological contexts is rare. Here, the authors present evidence for the ritual use of tobacco at Cotzumalhuapa, Guatemala, during the Late Classic period (AD 650–950). Detection of nicotine in residue analysis of three cylindrical ceramic vases recovered from cache deposits near the El Baúl acropolis suggests that these vessels contained tobacco infusions or other liquid preparations. These results suggest an ancient ritual practice involving tobacco for which there was previously no physical evidence in Mesoamerica.

Sedentary occupation of the southern Levantine coast spans from the Pre-Pottery Neolithic C to the Early Bronze Age Ib phase (c.7000–3100 BC). Sites dating to the Early Pottery Neolithic (c.6400–5500 BC) are scarce, however, potentially reflecting the effects of the 8.2ka climatic event. Here, the authors present the investigations at the submerged site of Habonim North off the Carmel Coast. Typological and radiocarbon dating indicate an Early Pottery Neolithic occupation and evidence for continuity of subsistence and economic strategies with both earlier and later Neolithic cultures. The results indicate the resilience of coastal communities in the face of significant climatic uncertainty and contribute to understanding human responses to environmental change.

Honneth afirma que o léxico das palavras diagnóstico e patologia estão ligadas à medicina. Na área social, essas noções só podem ser interpretadas indiretamente, ou seja, através das narrativas literárias, do campo artístico e da cinematografia. O Observatório Global de Patologias Sociais propõe-se a superar esse déficit. Este artigo exibe não apenas a análise conceitual, mas também as percepções inovadoras oriundas de um questionário online. Foram três questões. Por um lado, trata-se de descrever uma conceptualização de patologia social. Por outro, coletar sugestões para um instrumento empírico. Por fim, obter uma lista de patologias sociais. A análise demonstrou que há patologias restritas ao âmbito individual, enquanto outras são concernentes ao espaço coletivo. Nesse sentido, os efeitos e acometimentos também obedecem a categorias diferenciadas. Além do mais, aparecem percepções de patologias ligadas ao aspecto institucional, revelando uma preocupação com relação ao sistema social. Como conclusão, o texto sugere que a análise das patologias deve voltar-se à concretização social, institucional e histórica. Deste modo, os impulsos que, a princípio, eram tratados como subjetivos, individuais ou pessoais podem ser investigados como situações sociais coletivas e institucionais.
LEBENSWELT, COMMON SENSE Y LA RACIONALIDAD COMUNICATIVA

En la t eoría de la acción comunicat iva habermasiana nos enf rentamos al problema de la validez de cat egorías del ent endimiento comunicativo, que est án fácticamente enormemente cuestionadas. Es decir, Habermas ha definido al in terior del apart ado “Desacoplamiento de sistema y mundo de la vida” una sist emática de las f ormas de entendimiento. Allí aparecen doce f ormas de entendimiento que art iculan la di ferenciación de esf eras de validez con á mbitos de acción que evolucionan socialmente desde f ormas de ent endimiento primitivas preconvencionales hacia las má s avanzadas postconvencionales, llegando así hasta las dos últimas categorías (11 y 12) que Haberma s denomina forma moderna de entendimiento y que es el punto de partida de su teoría de la modernidad. Sin embargo, a este sistema categorial, debe hoy enfrentar una realidad completamente distinta a la del mundo moderno t ardo-capitalismo, que opera como ref erente fáctico de la t eoría. La nueva realidad consiste en una globalización sist émica que ha puest o en espacios nacio nales específicos a una pluralidad de mundos de la vida que van desde el preconvencional al postconvencional. Es decir, hoy, en el cuadro de la figura 28 presentado por Habermas en TAC 1981, II, todas las categorías aparecerían juntas, aunque diferenciadas en grados de evolución, y en un espacio y tiempo presente y continuo. Por tanto, hoy, cuando Habermas habla de Europa y del Estado de derecho democrático habla d esde el principio del discurso, o desde presupuestos teóricos comunicativos; cuando aborda temáticas referidas a integración social intercultural lo hace de sde una racionalidad del sentido común democrático (common sense) al que deben subordinarse esas otras tradiciones culturales.

The Anterolateral Barrel Subfield Differs from the Posteromedial Barrel Subfield in the Morphology and Cell Density of Parvalbumin-Positive GABAergic Interneurons

Published: March 2024

Layer 4 of the rodent somatosensory cortex has unitary structures called barrels that receive tactile information from individual vibrissae. Barrels in the anterolateral barrel subfield (ALBSF) are much smaller and have gained less attention than larger barrels in the posteromedial barrel subfield (PMBSF), though the former outnumber the latter. We compared the morphological features of barrels between the ALBSF and PMBSF in male mice using deformation-free tangential sections and confocal optical slice-based, precise reconstructions of barrels. The average volume of a single barrel in the ALBSF was 34.7% of that in the PMBSF, but the numerical density of parvalbumin (PV)-positive interneurons in the former was 1.49 times higher than that in the latter. Moreover, PV neuron density in septa was 2.08 times higher in the ALBSF than that in the PMBSF. The proportions of PV neuron number to both all neuron number and all GABAergic neuron number in the ALBSF were also higher than those in the PMBSF. Somata of PV neurons in barrels and septa in the ALBSF received 1.64 and 1.50 times more vesicular glutamate transporter Type 2–labeled boutons than those in the PMBSF, suggesting more potent feedforward inhibitory circuits in the ALBSF. The mode of connectivity through dendritic gap junctions among PV neurons also differed between the ALBSF and PMBSF. Clusters of smaller unitary structures containing a higher density of representative GABAergic interneurons with differential morphological features in the ALBSF suggest a division of functional roles in the two vibrissa–barrel systems, as has been demonstrated by behavioral studies.

Published: March 2024

DYT1 dystonia is a debilitating neurological movement disorder, and it represents the most frequent and severe form of hereditary primary dystonia. There is currently no cure for this disease due to its unclear pathogenesis. In our previous study utilizing patient-specific motor neurons (MNs), we identified distinct cellular deficits associated with the disease, including a deformed nucleus, disrupted neurodevelopment, and compromised nucleocytoplasmic transport (NCT) functions. However, the precise molecular mechanisms underlying these cellular impairments have remained elusive. In this study, we revealed the genome-wide changes in gene expression in DYT1 MNs through transcriptomic analysis. We found that those dysregulated genes are intricately involved in neurodevelopment and various biological processes. Interestingly, we identified that the expression level of RANBP17, a RAN-binding protein crucial for NCT regulation, exhibited a significant reduction in DYT1 MNs. By manipulating RANBP17 expression, we further demonstrated that RANBP17 plays an important role in facilitating the nuclear transport of both protein and transcript cargos in induced human neurons. Excitingly, the overexpression of RANBP17 emerged as a substantial mitigating factor, effectively restoring impaired NCT activity and rescuing neurodevelopmental deficits observed in DYT1 MNs. These findings shed light on the intricate molecular underpinnings of impaired NCT in DYT1 neurons and provide novel insights into the pathophysiology of DYT1 dystonia, potentially leading to the development of innovative treatment strategies.

The application of water to the surface of a paper or board web (in printing, coating, surface sizing etc.) causes a decrease in MD tension and a rapid increase in web width. Both processes have complex time-dependences whose details have direct practical relevance. For example, in color offset printing the amount of CD expansion between printing units determines fan-out and other misregister problems. No single traditional measurement can predict the amount of expansion or reveal its causes. We use KCL Vesikko and supplementary paper transmittance analysis to study the CD expansion and sorption dynamics for different papers and experimental conditions. With a new sorption model we can predict the experimentally observed movements of water inside paper.

Several clad segments from the same spent nuclear fuel rod were leached in a highly alkaline solution representative of the conditions expected in the current Belgian reference deep disposal design, and in presence of hydrogen. The results are compared with experiments that were conducted with clad and declad samples in a bicarbonate solution without presence of hydrogen. For the monitored radionuclides (238U, 90Sr, 137Cs, 129I, 99Tc), a fast initial release was observed. Afterwards, the release depended on the experimental conditions (medium, redox conditions) for uranium, strontium and technetium, but not for cesium and iodine. The cumulated released fractions were quantified at the end of the experiment.

The place of anthropology in the philosophy of education
Authors:   Matej Bel University Banska Bystrica, Slovak Republic, Golema Martin
Published: March 2024

The study tries to define the anthropology of dialogue as a specific way of thinking on human being; it grounds mainly in Tzvetan Todorov's findings. It comments basic theses of Buber, Levinas, Bachtin, Habermas and Todorov while underlining their mutual interpretability as well as similarity. Because of possible significance of this anthropological conception for professional teacher training, it recommends to reserve some space for the anthropology of dialogue in the area of the philosophy of education thus enabling it to come out of the shadow of more influential anthropological conceptions.

In the political aspect, it means bringing about rapprochement between nations. In Polish circumstances, Europeanism in the school context means carrying out activities aimed at making pupils realize the existence of the European Union, as well as its objectives and guiding rules. European education assumes that the European Community should be perceived not only in the institutional, economic or poHtical perspective, but mainly in the human one, as related to ever tightening bonds within the frameworks of the OId Continent that build an integrated community. However, the consciousness of the on-going changes can hardly be acknowledged as prevailing and well founded, since the probing research reveals that the knowledge of European problems among present and future PoHsh teachers from the Upper Silesian region is only fragmentary. Such a state of affairs should be a subject of retlection, especially in view of PoIand's imminent accession to the European Union.

1 RESUMO
 
No Brasil, o balanço hídrico climatológico tem sido amplamente utilizado para a gestão e planejamento dos recursos hídricos, tornando uma ferramenta importante para a análise dos impactos das mudanças climáticas na disponibilidade de água em diferentes regiões do Brasil. O objetivo desse estudo, foi calcular o balanço hídrico climatológico (BHC) mensal dos anos de 2019 a 2020 do estado do Tocantins.  Para a execução do mapa foi utilizado o software Rstudio®, utilizando médias mensais de temperatura e precipitação, para calcular a temperatura média mensal do ar no período de 01 de janeiro de 2019 a 31 de dezembro de 2020. O maior período de taxa de armazenamento de água no solo, foram nos meses de janeiro a abril, onde favoreceu o excedente hídrico. Já nos meses de maio a outubro prevaleceu o déficit hídrico.

CLIMATOLOGICAL WATER BALANCE AND MANAGEMENT OF WATER RESOURCES IN THE STATE OF TOCANTINS AS A SUBSID FOR IRRIGATION IN INCRA SETTLEMENTS
 
 
2 ABSTRACT
 
In Brazil, the climatological water balance has been widely used for the management and planning of water resources, making it an important tool for analyzing the impacts of climate change on water availability in different regions of Brazil. The objective of this study was to calculate the monthly climatological water balance (BHC) for the years 2019 to 2020 in the state of Tocantins. To execute the map, the Rstudio® software was used, using monthly averages of temperature and precipitation, to calculate the average monthly air temperature in the period from January 1, 2019 to December 31, 2020. The longest period of storage rate of water in the soil, were in the months of January to April, where the water surplus was favored. In the months of May to October, water deficit prevailed.

Published: March 2024

Abstract Objective: To determine the frequency and interobserver reproducibility of the magnetic resonance imaging (MRI) features considered diagnostic for autoimmune hepatitis. Materials and Methods: Two abdominal radiologists, blinded to pathology data, reviewed the MRI examinations of 20 patients with autoimmune hepatitis, looking for liver enhancement, lymphadenopathy, portal hypertension, and chronic liver disease. The pattern of liver fibrosis was categorized as reticular, confluent, or mixed. Interobserver agreement was assessed by calculating intraclass correlation coefficients and kappa statistics. Results: The most common abnormal finding on MRI was surface nodularity (in 85%), followed by liver fibrosis with a reticular pattern (in 80%)—categorized as mild (in 25.0%), moderate (in 43.8%), or severe (in 31.2%)—; heterogeneous liver enhancement (in 65%); splenomegaly (in 60%); caudate lobe enlargement (in 50%); and lymphadenopathy (in 40%). The interobserver agreement was almost perfect for surface nodularity (0.83), ascites (0.89), and liver volume (0.95), whereas it was just slight and fair for the degree of fibrosis and for heterogeneous liver enhancement (0.12 and 0.25, respectively). It was also slight and fair for expanded gallbladder fossa and enlarged preportal space (0.14 and 0.36, respectively), both of which are indicative of chronic liver disease. Conclusion: The interobserver agreement was satisfactory for surface nodularity (the most prevalent abnormal MRI finding), ascites, liver volume, and splenomegaly. Conversely, it was only slight or fair for common but less objective criteria.
Medial condyle hypoplasia in adolescent and young adult patients with trochlear dysplasia: a retrospective study

Published: March 2024

Abstract Objective: To determine the association between medial femoral condyle hypoplasia and trochlear dysplasia by analyzing the knee magnetic resonance imaging scans of young patients with or without trochlear dysplasia. Materials and Methods: This was a retrospective analysis of magnetic resonance imaging scans of the knees of young individuals (16-35 years of age): 30 patients with trochlear dysplasia and 30 individuals with no signs of patellofemoral instability. The ratios between the depth, width, and height of the medial and lateral femoral condyles (dLC/dMC, wLC/wMC, and hLC/hMC, respectively) were calculated, as was the ratio between the width of the medial condyle and the total width of the femur (wMC/FW). All of the values were determined in consensus by two radiologists. Results: We evaluated 60 patients: 30 with trochlear dysplasia and 30 without. The mean dLC/dMC, wLC/wMC, and hLC/hMC ratios were higher in the patients than in the controls (p < 0.05), whereas the mean wMC/FW ratio was lower in the patients (p < 0.05). The optimal cutoff values, obtained by calculating the areas under the receiver operating characteristic curves, were 1.0465 for the dLC/dMC ratio (76% sensitivity and 63.3% specificity), 0.958 for the wLC/wMC ratio (80% sensitivity and 73.3% specificity), and 1.080 for the hLC/hMC ratio (93.3% sensitivity and 93.3% specificity). Conclusion: Our findings confirm our hypothesis that trochlear dysplasia is associated with medial condyle hypoplasia.

Destaca o papel crucial desempenhado pela Agência Nacional de Avaliação da Qualidade e Acreditação (ANECA) e a imposição progressiva de fatores de impacto em periódicos científicos como expressão do fortalecimento do denominado capitalismo acadêmico e do trabalho digital nas universidades, no âmbito das reformas universitárias dos anos 2000.
Violência e vulnerabilização: o cotidiano de jovens negros e negras em periferias de duas capitais brasileiras
Authors: Silva Maria Edna Bezerra , Anuciação Diana , Trad Leny Alves Bonfim
Published: March 2024

Resumo A violência é um grave problema de saúde pública e constitui um fenômeno sócio-histórico, com causas e consequências diversas e múltiplas expressões. As principais vítimas seguem sendo as populações vulnerabilizadas e periféricas, nas quais se interseccionam dimensões como gênero, classe, raça e pertencimento social. Embora as questões étnico-raciais estejam presentes nos estudos que explicam o fenômeno da violência, estes tendem a não a considerar também fruto do racismo institucional. Este artigo pretende analisar dados de uma pesquisa quali-quanti que avaliou experiências de violência simbólica e estrutural vivenciadas por jovens negros/as de 15 a 29 anos de idade e moradores/as de bairros periféricos de duas capitais brasileiras - Recife e Fortaleza, a partir de grupos focais e entrevistas semiestruturadas. Foram enfatizados os lugares de fala que situavam a interseccionalidade, sobretudo de raça/cor da pele, pertencimento territorial e classe, na própria definição identitária. Em ambas as capitais a juventude negra trouxe à tona uma realidade comum: um horizonte limitado na definição de projetos de vida, tanto por questões econômicas quanto da demarcação concreta ou simbólica de lugares sociais para os quais seu acesso é interditado.
Desnortear, aquilombar e o antimanicolonial: três ideias-força para radicalizar a Reforma Psiquiátrica Brasileira

Published: March 2024

Resumo Este artigo é parte de uma pesquisa que buscou cartografar saberes e fazeres antirracistas em saúde mental por meio do acompanhamento das práticas de três coletivos de profissionais trabalhando na/com a rede de atenção psicossocial na cidade de São Paulo, o que possibilitou caracterizar suas estratégias de intervenção. Buscando contribuir para sua conceitualização, delineamos, por meio da revisão da literatura descolonial, três ideias-força que nos permitem dar corpo à descolonização da Reforma Psiquiátrica: o desnortear, que, em diálogo com Achille Mbembe e Frantz Fanon, nos convida à afirmação da loucura e da negritude - sem, no entanto, estabelecer fixações; o antimanicolonial, que se dá no fomento do exercício livre e contracultural de imaginar diásporas, em relação com as proposições de Édouard Glissant, Paul Gilroy e Lélia Gonzales quanto a uma (des)orientação atlântica na qual elementos da diáspora negra e da América Latina possam ressignificar negritude e desrazão; e o aquilombar, como práxis libertária que tem em sua gênese os quilombos como metáfora viva da radicalização das relações nas diferenças, a partir do quilombismo de Abdias do Nascimento, da quilombagem de Clóvis Moura, do (k)quilombo de Beatriz Nascimento e do devir quilomba de Mariléa de Almeida.
