Mining activity always presents threats to soil and water pollution. As an extractive industry, it disturbs the ground and the biodiversity associated with soil and plants. Its operations have led to severe geological and environmental problems, including the depletion of land and water resources, geological dangers, and ecological landscape devastation that may have accelerated the desertification of mining areas. This case study analyzed the soil’s physical and chemical properties in a nickel laterite mine, including soil erodibility K factor, soil pH, and heavy metal accumulation, as a basis for establishing mine management protocol during and post-mining operations in Tubay, Agusan del Norte, Philippines. Results determined a slightly alkaline pH level. An estimate of soil erodibility ranging from 0.016 to 0.066 was determined using the USLE-K factor, with the highest erodibility at Mine 7, where % silt is high and % sand is lowest. X-ray fluorescence (XRF) spectroscopy was used to analyze soil samples. The findings show that Ni, Fe, Co, and Mn in the soil were above the WHO-permitted limits. The surface soil had mean values of 9,239 ppm for nickel, 302,618 ppm for iron, 639 ppm for cobalt, and 5,203 for manganese. Heavy metals in soil may be consumed by crops and pollute land and water.
The Influence of Media in Autonomous English Learners
Authors: Martínez Alicia
Published: May 2023

The objective of this research is to know the impact that the media have had on the learning of English, taking into account factors such as linguistic globalization and the influence that the media have had on the spreading of the language. It is important to highlight that the media have been very present in the daily life of recent generations of individuals and although they can be perceived as a means to perform recreational activities, they have also functioned as a tool to learn or develop skills, including among them the learning of English. Nevertheless, several questions arise regarding the outcomes of an autonomous English learning process. This study intends to explore to what extent social media is a useful tool for people to learn a language autonomously through the experiences of several individuals that happen to learn English using media as an instrument.

Objectives The stagnation of mental activity in aging is associated with a decline in the function of all body systems, including cardiovascular, respiratory, genital, glandular, immune, and other organs. Cognitive disorders are also one of the most common problems in aging, which in turn exposes them at risk. Aging is associated with significant changes in memory, intelligence, perception, metacognition, recall, problem-solving, and other cognitive abilities. Therefore, this study was conducted to determine the effectiveness of cognitive rehabilitation in improving the cognitive abilities of the elderly. Methods & Materials The present study was a quasi-experimental study with a pre-test-post-test design with a control group. The statistical population included elderly people living in nursing homes in Kermanshah City, Iran, from which 24 people were selected by convenience sampling method and according to the inclusion criteria and were randomly assigned to the experimental and control groups. The experimental group underwent 20 sessions of 35 minutes twice a week with the Captain Log cognitive rehabilitation program, during which time the control group did not receive any intervention. After the intervention, post-test was performed for both groups. Research tools included a cognitive rescue skills questionnaire and Captain Log rehabilitation software. Descriptive statistics and univariate and multivariate analysis of covariance were used to analyze the data using SPSS software, version 24. Results The results of data analysis showed that F statistic for dependent components, including memory (F=193.57, P<0.001), selective attention (F=375.43, P<0.001), decision-making (F=39.20, P<0.001), planning (F=120.003, P<0.001), sustained attention (F=312.07, P<0.001), flexibility (F=91.44, P<0.001), and social cognition (F=4.48, P<0.05) are significant at the level of 0.05 and 0.01. Therefore, it can be concluded that the cognitive rehabilitation program has improved the cognitive abilities of the elderly. Conclusion Considering that cognitive rehabilitation has a significant effect on the neural activities of brain areas related to cognitive abilities and improves their function, it can be used as a suitable method to improve cognitive abilities.

Diabetes and obesity are diseases of relevance in the epidemiological context of Yucatan. The high coexistence and complex interaction between these pathologies have generated an initial characterization of the phenomenon called diabesity, however, it is necessary to resort to comprehensive theoretical frameworks that contribute to the understanding of this phenomenon. Diabesity is particularly relevant in the native population of Mexico. Taking the Maya from Yucatan as a case study, we propose that an ecological perspective of diabesity allows for the identification of the presence of factors at different scales of analysis that help to understand the phenomenon. In this article, we aim to analyze the phenomenon of diabesity in the context of the Yucatecan Maya population, given the demographic importance of this ethnic group in the country and due to the high prevalence of diabetes and obesity. In this descriptive review, we first describe the phenotypic and genotypic traits associated with diabesity; we then discuss the role of the sociocultural factors that have impacted the dietary pattern of the Maya and the available evidence regarding the phenotypic characteristics acquired during the early stages of development and their possible repercussions on metabolism and the presence of obesity and diabetes. Finally, we propose that the failure of insulin secretion and glucolipotoxicity are common factors and a possible unifying factor of diabesity among the Maya. For this purpose, we resort to primary sources of information, including original research articles and chapters from edited books about diabesity and socio-historical essays on the Maya population.

Black liquor evaporators upgrade - How many effects?
Authors: CANTRELL JAMES , STRAKA JIM
Published: May 2023

Black liquor evaporation is generally the most energy intensive unit operation in a pulp and paper manufacturing facility. The black liquor evaporators can represent a third or more of the total mill steam usage, followed by the paper machine and digester. When considering an evaporator rebuild or a new system, the key design question is how many effects to include in the system. The number of effects is the main design feature that determines the economy of the system and the steam usage for a given evaporation capacity. A higher number of effects increases steam economy and reduces energy cost to a point, but additional effects also have higher initial capital cost and increased power costs. This research paper uses life-cycle cost analysis (LCCA) as a method to determine the optimum number of evaporator effects for a new evaporator system. The same basic principles and method can also apply to existing evaporator rebuild projects.
How do mud balls form in lime kilns?
Authors: HINTON-BARBER PATRICK , TRAN HONGHI
Published: May 2023

Mud ball formation in lime kilns has been a persistent problem in many kraft mills, particularly for older kilns that are equipped with chains. A systematic laboratory study was conducted to examine how mud balls are formed and the key factors that affect ball formation. The results confirm the general mill experience that high moisture and high sodium contents in lime mud are the main contributing factors to ball formation. The high moisture content allows lime mud to agglomerate and grow to form balls, while the high sodium content helps make the balls hard and retain their shape. A ball formation mechanism is proposed to explain how mud balls form and grow near the kiln feed end.
Interfaith Marriage in Indonesia: The Controversy between MUI Fatwa and Surabaya District Court Decision
Authors: Saidah
Published: May 2023

This article is motivated by the issue of the Surabaya District Court's decision to legalize interfaith marriage. This issue has garnered a lot of opinions and criticism because it is considered to be not in line with the MUI fatwa that has been established. Therefore, the focus of this study is firstly on the legal basis of the MUI in establishing interfaith marriage, secondly on the considerations of the Surabaya District Court judge in deciding on interfaith marriage, and lastly on the legality of interfaith marriage in law and human rights. Using a sociological and normative approach, it can be concluded that the Surabaya District Court decision was rejected by various groups, especially the MUI, which was deemed to be no longer in line with the fatwa that had been established since long ago. Regarding this issue, the MUI will hold a meeting with the legal commission to discuss this issue. Nevertheless, the Surabaya District Court remains on the decision they issued because they have a basis for the decision. This study obtained data sources from secondary data by processing data from primary legal materials and secondary legal materials in the form of laws, civil procedure law books, and opinions of legal experts and theses. The results of this study are that interfaith marriage is recognized by state law if it is recorded in civil registration, as stipulated in Article 37 of the Population Administration Law, but it is not valid according to religion.
СТАНОВЛЕННЯ ЗБРОЙНИХ СИЛ В УКРАЇНІ ТА КРАЇНАХ БАЛТІЇ У ПЕРШЕ ДЕСЯТИЛІТТЯ ВІДНОВЛЕНОЇ НЕЗАЛЕЖНОСТІ
Authors: Войтенко Юрій Миколайович
Published: May 2023

У даній статті здійснюється огляд становлення збройних сил в Україні і країнах Балтії протягом першого десятиліття відновлення ними незалежності. У ній зазначається, що оскільки ці країни наприкінці літа 1991 року проголосили свою незалежність, то для її утримання необхідно було сформувати власні армії. Враховуючи те, що цей процес у часі досить тривалий, то починаючи з осені 1991 року збройні сили цих країн проходять своє становлення та трансформацію. Метою статті є аналіз процесу становлення збройних сил в Україні та країнах Балтії у перше десятиліття відновлення ними незалежності. Під час дослідження процесу становлення збройних сил в Україні та країна Балтії було використано методи: історико-порівняльний, ідіографічний, аналізу, синтезу та динаміки. Результати. У даній статті зазначається, що Україна базувала свою нову армію на колишньому радянському спадку, а країни Балтії відмовились від цього і почали з «чистого аркушу» формувати власні збройні сили. Проте вже у перші місяці незалежності росія почала здійснювати демілітаризацію України. Українська влада взаємодіяла як з країнами-членами НАТО, так і з країнами СНД, що не сприяло якісному реформуванню Збройних сил України. Країни ж Балтії, у перші роки відновленої незалежності, взяли курс на тісну співпрацю з НАТО і згодом набули членства у цій Організації. Якщо українське керівництво з самого початку незалежності приділяло більше увагу збройним силам, то згодом зменшувало видатки на його утримання в умовах економічної кризи. Країни ж Балтії, навпаки, почали посилювати видатки та збільшувати свої армії наприкінці 90-х рр. ХХ ст. в умовах курсу до НАТО. Політична еліта країн Балтії була більш ідейно монолітною та далекоглядною за українську, що відображалося також на питанні національної безпеки і зміцненні збройних сил. Висновки. Отже, на процес становлення збройних сил в Україні і країнах Балтії впливали внутрішні (зрілість політичної еліти, стан економіки, радянський спадок тощо) та зовнішні (потенційні ризики нової окупації, зміцнення росії і її геополітики щодо сусідів, розширення НАТО тощо) чинники.
СПРИЯННЯ БОГДАНА ГАВРИЛИШИНА РОЗВИТКУ МІЖНАРОДНИХ ВІДНОСИН УКРАЇНИ
Authors: Гаврилишин Петро Михайлович
Published: May 2023

Метою дослідження є з’ясувати, як представник української діаспори Богдан Гаврилишин посприяв у налагодженні та розвитку міжнародного співробітництва української держави. Методологічною основою дослідження стали методи аналізу, синтезу, принципи історизму та об’єктивності. Основні результати дослідження. Саме у визначений період часу на території Центральної та Східної Європи відбулись значущі геополітичні зміни у зв’язку розпадом Союзу Радянських Соціалістичних Республік та ліквідації Організації Варшавського договору. Ці події призвели до проголошення української незалежності та налагодження міжнародного співробітництва, з метою повноправного входження до грона вільних країн світу. У результаті цих процесів надзвичайно важливим було налагодження особистих міжлюдських контактів із провідними світовими лідерами та діячами. У зв’язку із цим на допомогу українській державності та дипломатії прийшов Богдан Дмитрович Гаврилишин. Висновки. У своїх мемуарах та даних ним у різний час інтерв’ю Богдан Гаврилишин ділився побаченими враженнями та здйсненими за його участі справами, які неможливо знайти в інших видах історичних джерел. Однією з провідних тем його як спогадів, так і діяльності стало покращення ефективності українського народу. Складовою ефективності є також встановлення міжнародних контактів. У результаті проведеного дослідження встановлено, що він був радником президента Леоніда Кравчука та трьох прем’єр-міністрів, допомагаючи їм встановлювати вагомих світових контактів. Науковець ввів українську еліту до Всесвітнього економічного форуму в Давосі, що значно розширило її контакти та можливості для розвитку України. Зневірившись в українських політиках, вчений у 2010 р. засновує Благодійний Фонд Богдана Гаврилишина, метою якого є підготовка значної групи молодих українців, які на власному досвіді вивчили б як функціонують передові держави Європи, та змогли б змінити Україну на краще.

This paper examined industrial waste management practices in Kaduna Metropolis, Kaduna State, Nigeria. A mixed method was used in carrying out the study as it involved surveys as well the use of GIS for site suitability. A total of 200 copies of the questionnaire were administered by adopting simple random sampling and used for the analysis. A simple lab test was conducted and findings revealed that there is a wide variation in the levels of zinc and nickel availability, though within the standards for drinking water, suggesting a change in water quality at various locations. High mercury levels in one of the samples are a reason for concern. It was recommended based on the findings amongst others that awareness and education regarding appropriate waste management, including collection and disposal, is essential for all construction workforces and should be provided by firms, in conjunction with the industry, The study recommends that the Kaduna State Government should consider measures, such as the introduction of regulatory policy, including site waste management plan (SWMP), Pay-As-YouThrow (PAYT), and landfill ban to divert material wastes from landfills. PPUV is a Pay-Per-Unit volume of waste generated and its purpose is to reduce waste and encourage reuse and recycling management of industries needs to change the misconception that landfilling is a cheaper option when compared to reuse and recycling. The design team should adopt effective design minimization measures, while other professionals are to ensure efficient waste reduction approaches.
Genomic Evolution in Pseudomonas fluorescens as a Result of Gradual Temperature Changes
Authors: Lee Spencer , Jonas Robert
Published: May 2023

As climate change continues to affect global temperatures, organisms will need to not only adapt but evolve to survive the changing climate conditions. Temperature selection experiments were performed on Pseudomonas fluorescens to select for growth at lower temperatures. The P. fluorescens temperature selection experiment selected for cells that can grow at a new minimum temperature which is over 20˚C lower than the optimal growth temperature (25-30˚C). Previous experiments established the low end of P. fluorescens’s growth temperature as 4˚C. The genomes of the newly selected and reference strains of P. fluorescens were sent for sequencing, and the results showed differences in protein sequence between the two strains. This experiment is a model for evolution as a result of gradual temperature change (similar to climate change) over generations, and the resulting genomic changes recorded show which protein families could evolve as an organism adapts to a gradually changing temperature.

Purpose: To analyze the association of systemic and ophthalmic disease in patients with pseudoexfoliation syndrome.Methods: We retrospectively reviewed the records of 207 patients with pseudoexfoliation syndrome and 201 age-matched controls without pseudoexfoliation syndrome seen from January 2016 to January 2021. Age, sex, systemic diseases such as diabetes mellitus, hypertension, cardiovascular and cerebrovascular disease, and ocular disease including retinal vascular occlusion, age-related macular degeneration (AMD), glaucoma, cataract surgery rate, complications related to cataract surgery, and ocular characteristics were compared. Factors associated with pseudoexfoliation syndrome were analyzed using logistic regression.Results: The frequencies of diabetes mellitus, hypertension, AMD, glaucoma, a history of cataract surgery, and complications related to cataract surgery were significantly higher in patients with pseudoexfoliation syndrome (all Ps ≤ 0.049). The pseudoexfoliation syndrome group had a significantly thinner global retinal nerve fiber layer, worse mean deviation and pattern standard deviation, and smaller dilated pupil size than the controls (all Ps < 0.001). In univariate and multivariate logistic regressions, the presence of diabetes mellitus (odds ratio [OR] = 1.613, p = 0.041), AMD (OR = 3.071, p = 0.001), and glaucoma (OR = 17.800, p < 0.001) were associated with pseudoexfoliation syndrome.Conclusions: Diabetes mellitus, hypertension, AMD, and glaucoma were more frequent in pseudoexfoliation syndrome patients. Since pseudoexfoliation syndrome is closely related to AMD and glaucoma, this requires clinical consideration.

Published: May 2023

Purpose: To report a rare case of acute red eye in a contact lens user.Case summary: An 18-year-old female presented with decreased visual acuity and ocular pain in the right eye for 4 days. The patient had used contact lenses for > 8 hours a day, even while sleeping at night, for the past 3 months. Corneal epithelial edema and punctate stromal infiltration along with diffuse conjunctival hyperemia and corneal limbal injection in the right eye were observed in slit lamp examination. The uncorrected and corrected visual acuities of the right eye were 0.02 (20/1000) and 0.16 (20/125), respectively. The right eye had an intraocular pressure of 10 mmHg, and the left eye was within normal range. The patient stopped wearing contact lenses and was prescribed steroid and antibiotic eye drops and artificial tears. The corrected visual acuity increased to 0.5 (20/40) on the first day of treatment and to 1.0 (20/20) after 2 months. The cornea and conjunctiva also returned to the normal appearance.Conclusions: It is important to differentiate contact lens-induced acute red eye from microbial keratitis. Discontinuation of contact lens use and education are required to prevent acute red eye caused by contact lens use.

The aim of our study is to examine the effect of differences in the levels of functionality of individuals with autism spectrum disorder (ASD) on level of family involvement.Our study has been carried out with the relatives of ASD individuals attending Aydın Efeler Municipality Autism Sports and Life Center. The Pediatric Functional Independence Criterion (WeeFIM) has been used to determine the functional independence levels of children, and The Family Impact Scale (FIS) has been used to measure the impact on the families of children with chronic disabilities. Our study was completed with the assessment of 98 individuals diagnosed with ASD (age=10.17±5.11, gender=15 female/83 male) and 98 pairs of their parents. The total WeeFim score was determined as 94.73 ±20.26 (independent) and the family impact scale scores were determined as 63.03 ± 12. The correlation analysis showed the sub WeeFIM impact the financial burden my family, self-care, communication, social status were statistically significant and weak correlation score between the total score (p<0.05; respectively, r=-0.025, r=-0.027, r=-0.310, r=-0.273). There was also a statistically significant, negative and moderate correlation between the total impact score of the FIS and the social status of the WeeFIM (p<0.00; r=-0.402).This study shows that family influence on individuals with ASD affects their social status. In addition, self-care, communication skills, and social status negatively affect individuals with more financial problems. In families with individuals with ASD, the independence of children affects the quality of life of families.

Enterobacter aerogenes representa uma bactéria gram negativa anaeróbia facultativa, não formadora de esporos. Apresenta-se como um microrganismo multirresistente que está diretamente relacionado a infecções oportunistas, sobretudo em ambiente hospitalar. Essa bactéria dispõe de diversos mecanismos para que se mantenha ativa, podemos destacar dentre estes, a utilização do sistema CRISPR-Cas para imunizá-las da infecção por elementos genéticos móveis. O sistema CRISPR (repetições palindrômicas curtas com intervalos regulares em cluster) trata-se de uma ferramenta genética responsável por clivar a fita dupla de DNA, em loci específicos através de endonucleases Cas. Diante do exposto o presente estudo teve como objetivo caracterizar amostra de Enterobacter aerogenes proveniente de colonização quanto aos sistemas CRISPR-Cas e comparar com amostra de infecção. Ao analisar o isolado de Colonização (Ea5A) foram identificados 31 genes que tinham relação com o sistema CRISPR, dentre esses, apenas 4 tinham associação com as endonucleases Cas, foram verificados inúmeros espaçadores na amostra. Ademais, a comparação entre o isolado de colonização e infecção, propôs que os genes independem da fonte de isolamento bacteriano. O sistema CRISPR-Cas trata-se de um assunto novo, porém já é considerado uma importante ferramenta para a engenharia genética.
