Objective: It is known that Thyroid Ultrasonography (US), guided by Fine Needle Aspiration (FNA), is a cost-effective and safe diagnostic method for evaluating thyroid nodules. Our purpose in the present study is to determine the reliability of the Thyroid Imaging Reporting and Data Systems (TIRADS) Scoring System for the evaluation of thyroid nodules.
Materials and Methods: A total of 3612 patients who were followed up in our endocrinology and general surgery clinic and operated on with the diagnosis of multinodular and nodular goiter were included in the study. The malignancy risk rate of all TIRADS categories was analyzed according to postoperative pathology results.
Results: Among the 724 patients, who were included in the study, preoperative FNA results were as 11.04% (n=80) benign, follicular, Hurthle cell neoplasia or suspected 8.83% (n=64), malignancy suspected 40.33% (n=292) and malignant 39.77% (n=288). We determined in the study that the malignancy was 72.15% (n=228) in TR-4 nodules and 97.1% (n=336) in TR-5 nodules. No correlations were detected between anti-TPO, anti-TG, TSH level, and malignancy.
Conclusion: TIRADS Scoring System was successful in predicting malignancy rates in the present study.
Dynamic response of an infinite timoshenko beam periodically supported subjected to a moving load
Authors: Lecheheb Mostefa , Lassoued Rachid
Published: July 2024

This study proposes an analytical approach to calculate the wave pattern produced by a moving load on a periodically supported Timoshenko beam. The Green's function for an unsupported beam is first assessed. Supports are then integrated using superposition, expressing the overall response as a combination of reactions from all supports and the external force. Bloch's theorem accounts for support periodicity, leading to a uniform system governed by a differential equation describing the rail response. Solving the homogeneous case derives the dispersion equation for Bloch waves and wave bands. The Bloch waves and dispersion curves represent the underlying mechanics of this dynamic scenario. The dynamic load creates a wave field expressed as a Bloch wave superposition, similar to modal decomposition for finite structures. The methodology determines the wave pattern from a constant velocity load traveling along a slender, periodically supported Timoshenko beam.

Due to increasing production of plastic and its piling up is a critical concern hence ways to degrade the plastic needs to be sought out. Microplastics (MPs) of the size of micron or less have been found everywhere, even in human blood, highlighting the adversity of the situation. Natural and microbial degradation mechanisms of MPs, focusing on polyethylene (PE) and polyethylene terephthalate (PET) have been explored by the study. Natural degradation is hindered by stability and hydrophobic properties of the polymers. Despite recycling efforts, a significant portion of PET waste ends up in landfills and the environment, posing threats to ecosystems and organisms. MPs are ingested by aquatic organisms, serve as substrates for unwanted microbes, and act as vectors for toxic chemicals. Atmospheric and aquatic fluxes contribute to the transport of MPs from production sources to marine environments. Microorganisms like bacteria, can degrade plastic polymers. Bacterial cultures are found to be effective in degrading MPs through extracellular and intracellular enzyme systems. Bacterial degradation of PE and PET has been demonstrated in laboratory conditions, with varying removal efficiencies and degradation durations. Abiotic factors like oxygen and light help in the PE degradation, while hydrolase enzymes are involved in PET degradation. For effective plastic management, a cyclic bioeconomy based method is necessary, which involves reconsideration of the entire value chain of plastic. Future-proofing plastic waste management requires delinking plastic production from fossil-based raw materials and energy sources. Additionally, addressing agricultural and food waste losses can contribute to reducing the carbon footprint associated with plastic production. Overall, understanding the microbial degradation of plastics offers promising avenues for combating plastic pollution and achieving a more sustainable plastic waste management system.

Introduction: Caroli's disease is a rare hereditary condition. It is characterized by segmental dilatation of the large intrahepatic bile duct with a cyst-like appearance. Caroli's disease is often found on typical imaging without specific symptoms. It can lead to progressive bile duct obstruction and cirrhosis. Therefore, early diagnosis and appropriate treatment are necessary for optimal outcomes and prognosis. Case presentation: A 12-month-old girl presented to the outpatient clinic of Dr. Soetomo General Academic Hospital, Surabaya, with complaints of jaundice, abdominal distension, pale stools dark tea-colored urine, hematemesis, pallor, and weight loss. She was malnourished and had anemic conjunctiva, icteric sclera, abdominal distension with hepatosplenomegaly, varicose veins on the abdominal wall, and edema in both lower extremities. Laboratory examination showed anemia (hemoglobin 7.3 g/dL), liver function abnormalities (Aspartate aminotransferase 191 U/L, Alanine aminotransferase 41 U/L, and Gamma-glutamyl transferase 148.3 U/L), hypoalbuminemia (albumin 2.47), cholestasis (total bilirubin 18.90 mg/dl and direct bilirubin 12.5 mg/dl), non-reactive HBsAg and reactive Cytomegalovirus Immunoglobulin G (IgG). Abdominal ultrasound showed cystic dilatation of right and left intrahepatic bile ducts consistent with Caroli's disease (Todani classification) with hepatomegaly. MRCP showed Caroli’s disease with multiple cystic dilatations of the right and left intrahepatic bile duct (IHBD), multiple peripheral small bile ductal dilatations, and hepatosplenomegaly. Conclusion: Appropriate imaging is critical in establishing the diagnosis due to the nonspecific clinical presentation of Caroli's disease. Caroli’s disease can result in biliary cirrhosis. Therefore, early diagnosis is necessary for the improvement of the outcome and prognosis of Caroli's disease
Bridging the Gap Between Community Schools and Rural Communities in Nepal Using Participatory Action Research
Authors: Shrestha Salpa , Raj Dangal Megh
Published: July 2024

This paper explores the engagement of parents with out-of-school children through community-based participatory action research in a rural community in Nepal. This study addresses the connection gap between local communities and community schools, which has resulted in consequences such as inconsistent attendance among students and low educational expectations among parents. By investigating the processes of formulating an action plan by a parent-led action group and analysing its execution, the research aimed to understand how participatory action research can foster a stronger bond between community schools and parents, thereby enhancing parental involvement in children’s education. The study draws on Mezirow’s transformative learning theory, incorporating concepts from Habermas’s public sphere and Freire’s notion of conscientization. It specifically focuses on the action group’s monthly meetings held over nine months and the collaborative outcomes that resulted. By emphasising targeted interventions, collaboration and a departure from deficit-focused approaches, the findings propose effective strategies for bridging the gap between community schools and rural communities in Nepal.

MYTHOLOGICAL IMAGES IN EMBROIDERY OF TURKIC PEOPLES (to the statement of the research problem)
Authors: Shaigozova Zhanerke
Published: July 2024

The embroidery of Turkic peoples is a unique phenomenon in all respects. More than one generation of scholars has been studying it step by step, reconstructing the semantic context of both the thing itself, its role in rites and rituals, and its form, ornamentation and colouring. The problem of reflecting archetypal motifs and mythological images in the art of embroidery occupies a special place in scientific research. With all the diversity of ethno-variants of embroidery: Uzbek, Karakalpak, Kazakh and others, it traces common images: Heavenly Father (deified Cosmos), the Great Mother in different variations - Umai, Ot-Ana, Zher-Su and other significant semantic constants of culture. In the process of research it was found out that the visual representation of archetypal images and motifs could be expressed from concrete anthropomorphic images to abstract word signs, i.e. had direct or indirect expression. The traditional practice of embroidery shows that “communicants” in the foreseeable period used indirect strategies much more often than “direct” ones, which is quite understandable by the Islamic paradigm - the prohibition of depicting living beings. These indirect statements in the most general form are characterised by a divergence of form: graphic and colouristic design. But, they were always understandable and clear for others. Of course, the main factor influencing the interpretation of indirect "statements" is the context in which embroidery is involved. This can be both the decoration of clothes, and the ritual and ceremonial function of embroidery itself in the bosom of culture.
The study was carried out under the grant of the Ministry of Science and Higher Education of the RK IRN AP23488164 – “Traditional and contemporary art of Kazakhstan in the focus of visual studies: iconography, semiotics and discourse”.

The Latex Diagnosis (LD) is performed through the determination of dry rubber (DRC), sucrose (Suc), inorganic phosphorus (Pi) and thiol (RSH) contents. It is carried out through the colorimetric method using a single cuvette spectrophotometer, which is time-consuming and requires a high volume of chemicals. It also needs to be executed as soon as the samples are collected so that limits the adoption of LD. The adaptation of the protocol to a multiplate reader and suitable conservation aimed to overcome the limitations. The experiments were carried out at the Indonesian Rubber Research Institute, Sembawa, Palembang, and Research Center for Biotechnology, Universitas Gadjah Mada, Yogyakarta. Various combinations of solution volumes, adapted from standard protocol, were tested. The closest slope of the standard curve to control was then applied to 7 randomly selected trees. The result showed that for Suc, the composition of 10 µL samples, 30 µL of 2.5 % TCA and 210 µL anthrone reagent was suitable for determination using a multiplate reader. The combination of 40 µL of sample, 85 µL of 2.5 % TCA and 125 µL mL FeSO4 solution was suitable for Pi determination, while 100 µL samples, 5 µL DNTB and 100 µL Tris is recommended for RSH. The measurement using a multiplate reader resulted in comparable contents (average deviations were 1.83, 2.69 and 3.51 % for Suc, Pi, and RSH, respectively), lower time and chemicals consumptions, and a larger number of sample handling compared to single cuvette method. This study also tested the effect of freeze-drying for sample conservation. The result indicated that freeze-drying was able to maintain the Pi level (deviation 0.93 %). However, it increased Suc (deviation 19.43 %) and decreased ascorbate (AsA) significantly (deviation 43.60 %); therefore, freeze-drying might not be suitable for conserving serum samples in the LD method.

Published: July 2024

Fish oil has been reported to have positive health effects because it is rich in n-3 essential fatty acids. This study aimed to determine the optimal conditions for achieving a high oil yield and omega-3 content from milkfish by-products using ultrasound-assisted extraction (UAE) combined with a d-limonene solvent. The Box-Behnken design (BBD) combined with response surface methodology was successfully used to determine the optimum extraction conditions for omega-3 fatty acids based on several factors: Temperature (30, 60 and 90 °C), solvent-to-sample ratio (2:1, 4:1 and 6:1 mL/g) and time (6, 38 and 70 min). The ANOVA results showed that sonication time (p < 0.05) and temperature (p < 0.05) had a significant influence on omega-3 fatty acids and the yield of extracted oil. The optimal extraction conditions for UAE were 68 min, 84 °C, and a solvent-to-sample ratio of 3:1 mL/g resulting in high oil recovery (21.95 %) containing omega-3 compounds (12.50 %). Additionally, the resulting oil was also further characterized by quality parameters (acid, peroxide, anisidine-total oxidation and iodine values) as well as the fatty acid composition. The developed milkfish oil met the IFOS™ (International Fish Oil Standards) criteria hence applicable for industrial oil production.

В настоящее время рассолы, вскрывающиеся при разработке различных месторождений полезных ископаемых, являются жидкими отходами и не перерабатываются. Высокое содержание промышленно-ценных компонентов в рассолах предопределяет экономическую эффективность их переработки при условии применения комплексных технологических схем. Из рассолов можно получить большой перечень товарной продукции, к тому же это сырье имеет ряд преимуществ перед месторождениями твердых полезных ископаемых. В статье описываются различные методы извлечения лития из рассолов, соляных растворов и геотермальных вод, включая осаждение, мембранное разделение, метод ионного обмена, адсорбцию и так далее. Целесообразность применения того или иного метода определяется рядом факторов: содержанием основных компонентов, обогащающих рассол, требованиями к продуктам, допустимой энергоемкостью. На рисунках также показаны технологические схемы переработки попутных пластовых рассолов с получением гидроксида лития.

At present, the brines uncovered during the development of various mineral deposits are liquid wastes and are not recycled. The high content of industrially valuable components in brines predetermines the economic efficiency of their processing on condition of application of complex technological schemes. From brines can be obtained a large list of commercial products, in addition, this raw material has a number of advantages over the deposits of solid minerals. This article describes various methods of lithium extraction from brines, saline solutions and geothermal water: including sedimentation, membrane separation, ion exchange method adsorption and so on. Feasibility of application of one or another method is determined by a number of factors: the content of the main components enriching the brine, the requirements for the products, the permissible energy intensity. The figures also show technological schemes for processing of associated formation brines to produce lithium hydroxide.

В статье изложено решение одной из важных проблем для горного производства – разработка новой инновационной технологии закладочных работ на основе тиксотропной закладочной смеси высокой плотности «пастовой закладки». Эти работы – одно из направлений в многогранной деятельности академика О.А. Байконурова. Описаны решения задачи по выбору материалов для закладочных работ, разработке технологии приготовления закладочных смесей и их транспортировки по трубам, оценке прочности закладки в массиве и экономической оценке новой технологии. Обосновано использование твердеющих закладочных смесей из мелкого заполнителя, которые обеспечивают эффективное использование их тиксотропных свойств: получение их высокой подвижности и сохранение ее в течение длительного времени, достаточного для доставки смеси на большое расстояние; образование изотропного искусственного массива, малое водоотделение и усадка массива. Показана необходимость активации закладочных смесей с целью более эффективного использования активности вяжущего с помощью активаторов-смесителей, «омагничивания» воды затворения и обработки лазером.

The article presents the solution of one of the important problems for mining industry – the development of a new innovative backfill technology based on a high-density thixotropic backfill mixture «paste backfill». These works are one of the directions in the multifaceted activity of Academician O.A. Baikonurov. The use of hardening filler mixtures made of fine aggregate is justified, which ensure the effective use of their thixotropic properties: obtaining their high mobility and maintaining it for a long time sufficient to deliver the mixture over a long distance; the formation of an isotropic artificial array, small water separation and shrinkage of the array. It is shown that it is necessary to activate the filling mixtures in order to use the binder activity more effectively with the help of activators – mixers, «magnetization» of the mixing water and laser treatment. Approaches to evaluating the effectiveness of the use of development systems with a hardening bookmark are described.
