Збагачення мінеральної сировини – це сукупність процесів переробки мінеральної сировини з метою виділення із неї корисних компонентів. В результаті збагачення корисних копалин отримуються два основних продукти: товарний продукт (концентрат, окатки) та хвости (відходи від переробки руди). Хвости складуються в хвостосховище – спеціальну гідротехнічну споруду для прийому та зберігання твердих та рідких відходів збагачення корисних копалин. Дані гідротехнічні споруди задіяні в технологічному циклі підприємства і несуть великі ризики для навколишнього середовища, особливо коли вони запроектовані, побудовані та експлуатуються без дотримання вимог нормативних стандартів та рекомендацій. Хвостосховище входить в систему хвостового господарства комбінату разом з системами транспортування хвостів та оборотного водопостачання. При проектуванні, будівництві та експлуатації хвостосховищ найбільше уваги приділяється їх надійності та безпеці експлуатації, оскільки руйнування таких об’єктів може призвести до катастрофічних наслідків. Надійність та безпека експлуатації хвостосховищ залежить від конструктивних рішень, які приймаються на основі інженерних вишукувань, моніторингу технічного стану та виконаних розрахунків стійкості огороджувальних споруд хвостосховищ із урахуванням специфіки будівництва таких споруд. Проектування, будівництво, експлуатація та консервація хвостосховищ здійснюється згідно з відповідними нормативними документами та стандартами. В даній статті представлено огляд та порівняльний аналіз вимог стандартів України з міжнародними стандартами при проектуванні хвостосховищ.

Проведено критичний аналіз створення та розвитку теорії розрахунку залізобетонних конструкцій, а також обґрунтовано необхідність її удосконалення на основі деформаційно-силової розрахункової моделі, яка реалізується з використанням повних експериментальних діаграм деформування (стану) бетону. Зокрема розглядається низхідна ділянка діаграми σb–εb (напруга – деформації) з метою виділення деяких критичних значень деформативності бетону. Одне з них – значення ebR, яке фіксує початкову точку низхідної гілки. Кінцева точка низхідної частини повної діаграми може бути зафіксована параметром eb,max – граничною деформацією, яка відповідає найбільшій досягнутій її величині в кінці діаграми деформування бетону, і відповідної цій деформації залишкової міцністю бетону Rb,min. Як показують численні експерименти, розвиток деформацій бетону і форма діаграми σb–eb істотно залежать від зміни швидкості деформування при випробуваннях. Встановлено, що характер спадної гілки, зокрема її протяжність, значною мірою залежать від швидкості деформування. Для абсолютно однакових бетонів, змінюючи швидкість деформування, можна отримувати різну граничну деформативність наприкінці діаграми σb–εb. Якщо випробовувати високоміцні бетони з невеликою швидкістю деформування, то можна зафіксувати значно більшу таку деформацію в кінці спадної гілки, ніж для бетонів меншої міцності, випробуваних з більшою швидкістю. Обґрунтовано закономірність залежності деформацій у кінці повної діаграми від швидкості силового деформування: якщо така швидкість наближається до нуля, гранична деформація такої діаграми за відповідного рівня зниження напруг буде прагнути нескінченності. Запропоновано також напрями вдосконалення розглянутої моделі шляхом впровадження різних трансформованих діаграм стану бетонних, армованих та посилених конструктивних елементів. Такі діаграми моделюються посередництвом експериментальних залежностей параметрів бетону σb–εb з урахуванням впливу різних фізичних, технологічних, силових та інших факторів.

Proactive management outperforms reactive strategies for wildlife disease control
Authors: Bletz Molly , Grant Evan , DiRenzo Graziella
Published: May 2024

Finding effective pathogen mitigation strategies is one of the biggest challenges humans face today. In the context of wildlife, emerging infectious diseases have repeatedly caused widespread host morbidity and population declines of numerous taxa. In areas yet unaffected by a pathogen, a proactive management approach has the potential to minimize or prevent host mortality. However, we typically lack critical information on the disease dynamics in a novel host system, have limited empirical evidence on efficacy of management interventions, and lack validated predictive models. As such, quantitative support for identifying effective management interventions is largely absent, and the opportunity for proactive management is often missed. Here, we consider the potential invasion of the chytrid fungus, Batrachochytrium salamandrivorans, whose expected emergence in North America poses a severe threat to hundreds of salamander species in this global salamander biodiversity hotspot. We developed and parameterized a dynamic multi-state occupancy model to forecast host and pathogen occurrence, following expected emergence of the pathogen, and evaluated the response of salamander populations to different management scenarios. Our model forecasts that taking no action is expected to be catastrophic to salamander populations. We also show that proactive action is expected to maximize host occupancy outcomes compared to ‘wait and see’ reactive management, thus providing quantitative support for proactive management opportunities. Additionally, we found that Bsal eradication is unlikely under any evaluated management options. Contrary to our expectations, even early pathogen detection had little effect on Bsal or host occupancy outcomes. Our analysis provides quantitative support that proactive management is the optimal strategy for promoting persistence of disease-threatened salamander populations. Our approach fills a critical gap by defining a framework for evaluating management options prior to pathogen invasion and can thus serve as a template for addressing novel disease threats that jeopardize wildlife and human health.

Published: May 2024

Tomando el caso de la documentación del terrorismo de estado por la sociedad civil chilena durante la última dictadura militar en Chile (1973-1990), y profundizando en la re-conceptualización de los archivos impulsada por el reciente “giro de los archivos”, este artículo describe nuestra propuesta de incluir otra escala y nivel de indagación en la investigación en archivos (de derechos humanos). Esto permite interrogar el acto documental, los artefactos y recursos técnicos que lo median, junto a las trasposiciones que re-inscriben lo enunciado en el futuro y en diversas arenas. Al mismo tiempo, y a diferencia de la lectura convencional que signa a los archivos como tecnologías de gobierno de poblaciones, proponemos que el archivo también puede constituir una tecnología de resistencia.

Published: May 2024

Bioactive compounds derived from plants are gaining attention worldwide because they have beneficial effects on humans. Rhizophora mucronata is a species of mangrove plant that has slightly dark leaves and glossy green on the top of the leaves and pale green on the bottom and acts as a natural antioxidant which has traditionally been used as a food ingredient and traditional medicine. Therefore, this article was written to review the bioactive compounds in Rhizophora mucronata leaves, antioxidant levels and the benefits of antioxidants in food and health products. This article summarizes relevant literature regarding R. mucronata which was tested using Phytochemical screening, FTIR and DPPH (1,1-diphenyl-2-picrylhydrazyl) methods. Phytochemical analysis revealed the presence of alkaloids, flavonoids, steroids, phenolics, tannins and saponins. Based on the FTIR test, R. mucronata leaf extract showed the presence of –OH, C-H (aromatic), C=C (aromatic), and C-O groups. The antioxidant capacity expressed in IC50 (mg/mL) shows that R. mucronata has the potential to be used as a source of natural antioxidants. Antioxidants can play a role in improving the sensory quality of a food product and as a natural bactericidal so that it can be used to maintain aquatic biota and food preservatives. In addition, antioxidants contained in mangroves can prevent aging, wrinkles, cancer, obesity, and diabetes mellitus.

Authors: Bhuiyan Mahbubur Rahman , Islam Md Ziaul
Published: May 2024

Background: Autism Spectrum Disorder (ASD) is a neurodevelopment disorder and an emerging public health issue globally which is associated with huge burden to the family, community and the nation. Study was conducted to find out the coping strategies for financial burden of the family with ASD children.
Methods: A cross-sectional study on 154 children with ASD was carried out from July 2015 to June 2016 where data were collected from two special schools and two specialized hospitals of Dhaka city. Data were collected by face-to-face interview with semi-structured questionnaire following systematic random sampling technique. Informed written consent was taken from the parents.
Results: Majority (73.4%) of the children were male and average monthly family income and total treatment cost was Tk. 41785.7 and Tk. 23076.62 respectively. However, coping strategies were adopted by the family “changing lifestyle” (96.8%), “accepting the reality” (100%), “minimizing family investment” (90.3%). Again, 52.5% families minimized family investment as coping strategies, 52.2% families had financial constraint as consequences of financial burden, which were significantly higher in comparison with others (p<0.05).
Conclusion: ASD foist huge financial burden to the families of affected children. To compensate this financial burden, families adopted different coping strategies like changing lifestyle, taking social support, relying on religion, minimizing family investment, accepting reality etc. Appropriate early diagnostic facilities should be available to estimate the actual burden of the country.

Published: May 2024

Background: Acute pancreatitis is a potentially life-threatening condition characterized by inflammation of the pancreas. Early identification of patients at risk of severe disease is crucial for devising appropriate management strategies and improving outcomes. The aim of the study was to investigate the efficacy of BISAP score as predictor of in-hospital outcome in patients with acute pancreatitis. Methods: This was a longitudinal study conducted in Department of Medicine, Sir Salimullah Medical College Mitford Hospital, Dhaka from January 2023 to December 2023. After ethical approval, a total 107 subjects were included in this study based on inclusion and exclusion criteria. Severity of the disease was assessed by BISAP score. Theoutcome determinants were length of hospital stay, complete recovery, partial recovery with complication, transfer to ICU and mortality. Chi Square test, Binominal Regression analysis and Receiver operator characteristic (ROC) curve analysis were performed as applicable. p value <0.05 was considered as the level of significance. Results: The mean BISAP score among 107 study participants was 2.00 ± 0.76. Patients with BISAP score ³3 had significantly increased odds of prolonged hospital stay (OR: 11.226; 95% CI: 2.985- 42.222; p<0.001), higher rate of partial recovery with complications (OR: 7.302; 95.325% CI: -20.997; p<0.001). <0.001), and greater likelihood of intensive care unit (ICU) transfer (OR: 1.136; 95% CI: 0.968-1.333; p=0.004). A BISAP score cutoff value of ³3 was associated with increased length of hospital stay (sensitivity 91.3%, specificity 97.6%, AUC=0.945), partial recovery with complications (sensitivity 83.3%, specificity 96.4%, AUC=0.899), and ICU transfer (sensitivity 75%, specificity 80.6%, AUC=0.778).Conclusion: It can be concluded that increased BISAP score can be served as an independent predictor of in-hospital in patients with acute pancreatitis (AP).

Background: Oral mechanical bowel preparation is a routine practice prior to colorectal surgery in many centers. Virtually all colorectal surgeons consider a mechanically cleansed and empty bowel as one of the prerequisites for a safe colonic resection and anastomosis. Various agents had been used in different centers in mechanical bowel preparation.
Methods: A comparative prospective interventional analysis of preoperative elective bowel preparation in children with polyethylene glycol versus polyethylene glycol and mannitol was conducted on 60 children underwent elective GIT surgery between July 2014 and June 2016. The patients were allocated into 2 groups by simple random sampling, 30 in each group. Children of 6 months to 14 years were selected as study population. In group I, PEG was given per orally or through nasogastric tube at the rate of 1.5 gm powder/kg/dose, in group II, PEG & Mannitol were given orally or via nasogastric tube. PEG was administered as same dose of group I and mannitol 20% at a dose of 10 ml/kg/dose. All patients received prophylactic intravenous antibiotics (ceftriaxone + metronidazole) preoperatively as well as in postoperative period. All children were investigated preoperatively and post operative follow up was recorded. Structured questionnaire was used to collect information regarding preoperative status and post operative follow up. Statistical assessments were done by SPSS version 21. An Ethical clearance had been sought.
Results: Sixty children underwent mechanical bowel preparation prior to GIT surgery. 30 with PEG (group I) and 30 with PEG and Mannitol (group II). Our outcome variables were wound infection, anastomotic leakage, and Electrolyte balance. Demographic pattern also evaluated. The age range of both groups was 6-68 months, p value 0.987. In both group male and female were same in number, 16 male and 14 female each in both groups. Wound infection occurred 3 cases (10%) in PEG group and 2 cases in PEG and Mannitol group, p value 0.64. No anastomotic leakage in PEG and Mannitol group and only 1 leakage in PEG group. No Electrolyte imbalance was found in both groups. No mortality was recorded in this study.
Conclusions: No significant difference was found between the two study groups in respect of wound infection, anastomotic leakage and electrolyte balance. Ingestion of two drugs did not have any better outcome. So, mannitol can be omitted in MBP in children.

Published: May 2024

Pre–Eclampsia is a disorder in 2nd half of pregnancy, characterized by a combination of hypertension, proteinuria, and edema, secondary to decreased placental perfusion. Clinical studies suggest histo-morphological changes in the placenta of pre-eclamptic women compared to normotensive pregnant women. This study aimed to compare the histo- morphological changes of the placenta in selected pre-eclamptic and normotensive pregnant women.
Methods: Two hundred twenty pregnant women were selected with inclusion and exclusion criteria from 3 different medical colleges and divided into two groups. A study group comprised 110 pre-eclamptic women, and a control group comprised 110 normotensive pregnant women. After delivery, tissue samples were collected from the placenta and prepared for histopathological studies by hematoxylin and eosin stain. The mean number of areas of syncytial knot formation, the mean number of areas of cytotrophoblast cell proliferation, the mean number of areas of fibrinoid necrosis, and the mean number of areas of hyalinized villi of pre-eclamptic and normal pregnant women were evaluated. We evaluated the morphology by weight, diameters, number of cotyledons, and placental infarcts.
Results: The mean number of areas of syncytial knot formation, cytotrophoblastic cell proliferation, fibrinoid necrosis, and hyalinised villi were significantly higher in the study group compared to the control group. The mean weights, diameters, and the number of cotyledons were considerably lower in the study group compared to the control group. Moreover, the number of infarcted areas was significantly higher in the placentas of pre-eclamptic women.
Conclusion: There are histomorphologic changes in the placenta of pre-eclamptic women.

Revisiting Childhood: A Phenomenological Study on Art Students' Lived Experiences of Memory and Fantasy Drawings
Authors: Ankyiah Francis
Published: May 2024

This phenomenological study explored art students' lived experiences of creating memory and fantasy drawings of their childhood. In-depth semi-structured interviews were conducted with 12 undergraduate art students who completed a drawing assignment revisiting their childhoods through memory and fantasy renderings. Data were analyzed using interpretative phenomenological analysis to extract themes and insights into the essence of the phenomenon. Findings revealed that memory drawings evoked vivid recreations of specific moments and relationships from childhood, eliciting emotional responses ranging from nostalgia to distress. Fantasy drawings provided opportunities for imaginative reworking of childhood experiences, allowing expression of latent wishes, fears, and curiosity. The act of rendering childhood memories and fantasies in visual form allowed access to embodied aspects of past experience and enabled new perspectives. Participants described the assignment as an insightful rediscovery and reevaluation of childhood. The study provides an enhanced understanding of how memory and fantasy drawings provide evocative access to lived dimensions of childhood among art students. The visual articulation and symbolic processing of remembered and imagined childhood experience facilitated self-reflection, emotional exploration and integration.

Authors: Hillesheim Selma , Thadeu Moretti Méricles
Published: May 2024

Este artigo apresenta uma possibilidade metodológica para o desenvolvimento de programas de formação continuada para professores pedagogos. Essa perspectiva metodológica, intitulada de Engenharia Didática Colaborativa Semiocognitiva, foi concebida mediante a seguinte problemática: como abordar a aprendizagem da geometria com um grupo de professores pedagogos, considerando a perspectiva Semiocognitiva da teoria dos Registros de Representação Semiótica? Procurando solucionar esse impasse, viu-se emergir uma nova perspectiva metodológica a partir de uma tessitura entre a Engenharia Didática, a pesquisa Colaborativa, a Engenharia Didática Colaborativa e a teoria Semiocognitiva de Duval para a aprendizagem da geometria. O desenvolvimento do programa de formação, por intermédio dessa nova perspectiva metodológica, com os professores pedagogos, apontou que houve uma percepção da importância dos temas discutidos e, como consequência disso, possibilidades de incorporação desses elementos semiocognitivos em suas práticas pedagógicas.
Comparative characterization of supragingival plaque microbiomes in malocclusion adult female patients undergoing orthodontic treatment with removable aligners or fixed appliances: a descriptive cross-sectional study
Authors: Zheng Jiajia , Wang Xiujing , Zhang Ting , Jiang Jiuhui , Wu Jiaqi
Published: May 2024

Objectives

This study aimed to explore the effects of removable aligners and fixed appliances on the supragingival bacterial communities in adult female patients undergoing orthodontic treatment.

Methods

Supragingival plaque samples from 48 female individuals underwent microbiome analysis (16S rRNA gene sequencing) using PacBio Sequel sequencing. The study included 13 adults without orthodontic treatment needs as the control group (Group C), and 35 patients with comparable initial orthodontic conditions who received treatment at a university clinic in Beijing, China. The treatment involved either traditional fixed brackets (Group B, n = 17) or Invisalign® aligners (Group AT, n = 18). Bioinformatics methods were used for data analysis.

Results

From the 48 plaque samples, a total of 334,961 valid reads were obtained, averaging 6,978 sequences per sample. The 16S rDNA sequences were classified into 25,727 amplicon sequence variants (ASVs). Significant variances in alpha and beta diversity among the groups were noted. Group B microbiome exhibited an increased presence of Gram-negative bacteria. At the phylum level, Actinobacteriota was significantly more prevalent in Group C samples, while Bacteroidota was enriched in Group B samples. Family-level relative abundance analysis showed a notable increase in Saccharibacteria (formerly TM7) and Prevotellaceae in Group B. Genus-level analysis revealed a significant rise in Lautropia in Group AT. Fixed orthodontic appliances were linked to oral microbiome changes, notably an enhanced relative abundance of anaerobes, including periodontal pathogens.

Conclusion

The observation points to the impact of orthodontic appliance on the oral microbial community, highlighting the difference between traditional braces (Group B) and clear aligners (Group AT)in terms of the predominance of anaerobic and gram negative bacteria. This emphasizes the importance of considering the microbiological effects when choosing orthodontic appliance and underscores the need for tailored oral hygiene practices for individuals undergoing these treatments. This research might provide insights that could assist in the development of innovative cleaning techniques and antibacterial materials.
