Published: April 2024

Одной из частых причин врожденных пороков развития плода является недостаточное поступление витаминов в организм матери, важнейшим из которых является витамин B9 (фолиевая кислота). Еще одной причиной осложнений во время беременности может служить действие на организм беременной женщины свободных радикалов. В связи с этим большой интерес представляет изучение и сравнение антиоксидантных свойств фолиевой кислоты в лекарственных средствах и БАД, которые часто назначаются беременным в процессе прегравидарной подготовки и во время беременности. С этой целью было проведено исследование антиоксидантной активности (АОА) лекарственных препаратов и БАД фолиевой кислоты. В результате определения АОА методом Фолина-Чиокальте и в тесте связывания OH-радикалов активность уменьшалась в ряду «Фолиевая кислота» АОА «Марбиофарм» > «9 месяцев Фолиевая кислота» АО «Валента Фарм» > «FOLIC ACID 400 MCG» Nature's Bounty Inc. > «Фолиевая кислота 400 мкг» АО ПФК Обновление > «FOLIC ACID 400 MCG» Solgar. Антиоксидантная способность всех исследуемых образцов была ниже активности аскорбиновой кислоты.

Цель - изучить эффективность нефиксированных комбинаций антигипертензивной терапии (АГТ) при развитии бевацизумаб-индуцированной артериальной гипертензии (АГ) в эксперименте у нормотензивных крыс линии Wistar для определения первой линии терапии кардиотоксичности по типу АГ. Результаты: перед началом АГТ - через 12 дней после 1 инъекции бевацизумаба или через 5 дней после 2 инъекции бевацизумаба уровень АД во всех экспериментальных группах повысился с высокой степенью достоверности (р<0,01). У животных, получавших комбинацию телмисартан 3,1 мг/кг/сутки + амлодипин 0,4 мг/кг/сутки, АД снижалось эффективнее, чем у животных, получавших комбинацию лизиноприл в дозе 0,8 мг/кг/сутки с гидрохлортиазидом в дозе 2 мг/кг/сутки (р<0,05).
«Быть собой» или «радовать себя»? Терапевтические технологии, эмоции и неравенство в современной России
Authors: Терешина Дарья
Published: April 2024

В современном мире терапевтический дискурс и психотерапевтические практики играют все большую роль в процессах субъективации. В данной статье исследуется, каким образом различные подходы к управлению эмоциями влияют на социальные взаимодействия и карьерные траектории в социальных и институциальных контекстах. Основываясь на двух кейсах – изучения практик молодых профессионалов, работающих в культурных институциях, а также исследовании деятельности консультантов компании прямых продаж Мери Кей, статья демонстрирует, что терапевтический проект предлагает множество эмоциональных режимов, которые распространяются в социальных, экономических и культурных средах. Анализируются техники самоанализа и «проговаривания», востребованные среди представителей городского образованного среднего класса. Данные терапевтические техники основаны на рефлексивной интерпретации себя, умении распознавать эмоции и поисках своего «аутентичного» Я. Они сравниваются с практиками позитивного мышления на примере компании Мери Кей. Кроме того, уточняется вопрос о стратифицирующей роли эмоциональных компетенций. Работа над собой в контексте сетевого маркетинга Мери Кей особенно значима для женщин из малых городов, ограниченных в своих ресурсах и возможностях социальной мобильности. Они рассматривают эмоциональную работу и навыки позитивного мышления как ключевые инструменты для достижения успеха. Напротив, представители столичного образованного класса склонны к освоению навыков психологизированной рефлексии и умению говорить на языке «сложных чувств». Учитывая тот факт, что эмоциональные компетенции начинают играть все более значимую роль в процессах социальной мобильности и поддержания классовых различий, встает вопрос о существовании эмоциональной стратификации в современном российском обществе.

Wprowadzenie

Przeprowadzono retrospektywne badanie kliniczne w celu oceny wyników leczenia u pacjentów z nagłą głuchotą. Porównano dwie metody leczenia: glikokortykosteroidami skojarzonymi z hiperbaryczną terapią tlenową oraz samymi glikokortykosteroidami.

Materiał i metody

W badaniu wzięło udział 65 dorosłych pacjentów z nagłym niedosłuchem czuciowo nerwowym podzielonych na dwie grupy: 1) 37 pacjentów leczonych glikokortykosteroidami podawanymi dobębenkowo i doustnie oraz hiperbaryczną terapią tlenową oraz 2) 28 pacjentów leczonych glikokortykosteroidami podawanymi dobębenkowo i doustnie, bez hiperbarycznej terapii tlenowej. Ocenę audiologiczną przeprowadzono za pomocą audiometrii tonalnej.

Wyniki

Poprawa słuchu mierzona jako poprawa średniego tonu czystego wyniosło 12 dB HL u pacjentów leczonych glikokortykosteroidami w połączeniu z hiperbaryczną terapią tlenową i 13,7 dB HL u pacjentów leczonych tylko glikokortykosteroidami. Całkowite wyleczenie lub wyraźną poprawę zaobserwowano u 27,8% pacjentów z pierwszej grupy i 25,5% z drugiej grupy. W obu grupach największy i zbliżony odsetek stanowili pacjenci, u których poprawa progów słyszenia była mniejsza niż 10 dB HL.

Wnioski

Pacjenci leczeni glikokortykosteroidami i hiperbaryczną terapią tlenową oraz pacjenci leczeni tylko glikokortykosteroidami osiągnęli podobną poprawę słyszenia. Prospektywne, kontrolowane i randomizowane badanie kliniczne mogłoby dostarczyć rzetelnej wiedzy dotyczącej stosowania hiperbarycznej terapii tlenowej w leczeniu nagłej głuchoty.
PARALLEL MESHLESS RADIAL BASIS FUNCTION COLLOCATION METHOD FOR NEUTRON DIFFUSION PROBLEMS
Authors: Tanbay Tayfun
Published: April 2024

The meshless global radial basis function (RBF) collocation method is widely used to model physical phenomena in science and engineering. The method produces highly accurate solutions with an exponential convergence rate. However, due to the global approximation structure of the method, dense node distributions lead to long computation times and hinder the applicability of the technique. In order to overcome this issue, this study proposes a parallel meshless global RBF collocation algorithm. The algorithm is applied to 2-D neutron diffusion problems. The multiquadric is used as the RBF. The algorithm is developed with Mathematica and eight virtual processors are used in calculations on a multicore computer with four physical cores. The method provides accurate numerical results in a stable manner. Parallel speedup increases with the number of processors up to five and seven processors for external and fission source problems, respectively. The speedup values are limited by the constrained resource sharing of the multicore computer’s memory. On the other hand, significant time savings are achieved with parallel computation. For the four-group fission source problem, when 4316 interpolation nodes are employed, the utilization of seven processors instead of sequential computation decreases the computation time of the meshless approach by 716 s.

The work under analysis is doubly indispensable in view of its disruptive component, but also as a relevant update to the debate around the social and political impact of DMs in contemporary societies. We categorise it as disruptive in that it uses data analysis methods from psychology, such as measuring skin conductance when paying attention to the news, which are still a minority in the field of communication sciences, as well as sociology. We also categorise the work as a powerful contribution to updating the debate around new and emerging forms of digital inequality, with widespread implications in the socio-economic and political spheres, conditioning access to political participation.

This study created membrane nanofibres using the electrospinning method and newly studied a mixture of ENR and ABS. The two-level complete factorial designs with centre points were used to characterise the functionality of the constructed membrane. The variables considered for experimental design were the polymer concentration, materials ratio (ENR concentration), applied voltage and distance between the needle tip and collector. According to the analysis of variance (ANOVA), the concentration of solution and distance were statistically significant parameters that affected the tensile properties of the ENR/ABS electrospun membrane. A mathematical model of the tensile property of polymer fibres was created using Response Surface Methodology (RSM). This model was built based on essential process factors. The mechanical properties of the electrospun ENR/ABS membrane compromised with 25wt% of solution concentration, 30% ratio of ENR, the voltage at 22.5kV and 15 cm of distance create an excellent tensile strength with desirability of 0.94. The influence of ENR on the morphology of ENR/ABS fibres was characterised by Scanning Electron Microscopy (SEM). The result showed beaded fibre and decreased fibres due to the low concentration of the solution and high ratio of ENR (50%). The contact angle measurements indicated that the electrospun fibre membrane was hydrophobic with a water contact angle of 136°. The addition of ENR showed a reduction in contact angle to 119°. The existence of ENR will change the features of the membrane, and investigations have demonstrated that RSM has been efficiently developed to acquire the interaction effects of processing parameters.
Effect of Mesh Coarseness on Slope Stability Analysis Using 2D and 3D Finite Element Method

A comprehensive understanding of slope stability is essential for ensuring the safety and durability of structures built on or near slopes and mitigating the risks associated with landslides and slope failures. Slope stability is typically evaluated using the factor of safety (FOS) based on the critical slip surfaces. The calculation of FOS is commonly executed using Limit Equilibrium Method (LEM) by dividing the slope into several vertical slices. However, the stability analyses using Finite Element Method (FEM) have gained significant attention in geotechnical engineering due to their ability to simulate slope behaviour and predict stability accurately by employing mathematical models and computational algorithms. Hence, this paper aims to analyse the FOS of the unreinforced slope using 2D FEM and 3D FEM conducted through computer software while examining the influence of different mesh coarseness. Besides that, the formation of critical slip surfaces and the displacement behaviour of the slope are also presented. A slope geometry model was analysed using PLAXIS 2D and PLAXIS 3D with different mesh coarseness. The findings were compared and discussed. The findings reveal that the values of FOS generated by 3D FEM are slightly larger compared to 2D FEM analysis, ranging from 1.27% to 2.56%. On the other hand, the effect of mesh coarseness indicates that coarser mesh sizes yield higher FOS values compared to finer mesh sizes. The shape, location and depth of the critical slip surfaces are consistent for each analysis in both methods. However, the maximum displacement values differ for each mesh coarseness, as the locations of maximum total displacement are identified at different nodes due to varying numbers of elements but still within the same potential failure zone. Overall, this comparative study is crucial in ensuring the validity of the performed analyses. Understanding the capabilities and limitations of 2D and 3D numerical analyses to achieve reliable and accurate results is important to balance mesh coarseness and computational efficiency.

Graph data appears in broad real-world applications in modelling complex objects in big data. Effective analysis of graph data provides a deeper understanding of the data in data mining tasks, including classification, clustering, prediction, and recommendation systems. Mining a large number of graphs becomes a challenging task because state-of-the-art methods are not scalable due to the memory limit. To address this issue, we propose a novel approximate random sampling method for large-scale graph data classification. In this approach, we applied a representation method to encode each graph as a record of a vector string and a set of graphs as a set of N records in a file. Then, we partition the set of records into disjoint subsets of data blocks, making each data block a random sample of the data file. After that, we randomly select a subset of data blocks, each being a random sample of the graph dataset, and compute the different graph property distributions. Since the data blocks in this model are much smaller than the entire data set, it is more efficient to analyze them on a standalone small machine, and multiple data blocks can be analyzed on multiple nodes of the cluster in parallel. Finally, we classified the graphs of data blocks using the SVM algorithm. In experimental evaluation, our proposed method outperformed state-of-the-art graph kernels on graph classification datasets in terms of accuracy.

Peat soil is frequently seen as a soil foundation concern which normally required soil stabilization work. This study is conducted to assess the strength of peat soil mixed with GeoPolySoilS as a proposed ground improvement work for peat soil in Kampung Johan Setia in Klang Selangor, Malaysia. In order to look into the strength improvement of this peat soil, laboratory tests were conducted namely Unconfined Compressive Strength Test (UCT) and Calfornia Bearing Ratio Test (CBR). The highest strength of UCT for the uncured soils with 14% GeoPolySoilS is 161 kPa whilst for the sample that was cured for 7,14,28 and 50 days, the highest value of UCT with 20% GeoPolySoilS are 58.08 kPa,61.66 kPa, 95.62 kPa and 80.04 kPa respectively. For the CBR value, the highest top layer value is 8.12% for peat soil mixed with 14% GeoPolySoilS whilst the highest value for the bottom layer is 62.25% for unsoaked CBR. For soaked CBR, the highest top layer value is 5.82% for 20% GeoPolySoilS and the highest value for bottom layer is 43.07%. The strength of the modified peat increased with the increased of curing time and the percentage of GeoPolySoilS.

Solar still was successfully used for the desalination of saline water in many arid and oceanic regions of the world. But the yield of solar still was found very low and fluctuating. The new develop system with the flashing of solarheated water is found possible during the study of flashing of hot water in many thermal processes used during the chemical and pharmaceutical processes. A compact and effective desalination system using solar energy had designed during the research work from the design reviews collected from flashing hot water devices used in many thermal processes. The compact flash chamber and flash steam condenser are critical components developed for the novel desalination system using locally available materials during the research work. In present experimental work a flash chamber is designed for flashing of solar heated water. Experimental work shows that by increasing the mass flow rate of water from 0.01 kg/sec to 0.02 kg/sec the distillate output of water could be increased with higher temperature of water. It shows that around 38% of higher distillate output in water could be achieved with development of new system.

Cadmium Telluride (CdTe) photovoltaics, incorporating a thin film of Cadmium Sulfide (CdS), present a costeffective yet less efficient solar cell technology. Improving CdS/CdTe solar cell efficiency involves optimizing parameters like doping concentration and CdS layer thickness. However, limited research on cell defects necessitates a comprehensive analysis, including the often-overlooked impact of temperature. This study aims to analyze defect-free and defective CdS/CdTe solar cells, exploring the effects of doping concentration and other parameters. Using the SCAPS-1D simulator, design parameter variations will be investigated, and key metrics— open-circuit voltage (Voc), short-circuit current density (Jsc), fill factor (FF), and efficiency (η)—will be extracted. Simulation results indicate minimal efficiency impact from increased doping concentration in the ntype CdS layer for defect-free devices. The optimal doping concentration for CdS is 5 × 1018 cm-3, with an optimum electron affinity of 4.0 eV. CdS thickness shows no significant efficiency impact, with the chosen optimum at 10 nm. In the defect-free CdS/CdTe solar cell, key metrics were Voc: 1.06 V, Jsc: 24.60 mA cm-2, FF: 87.89%, and η: 23.01%. Analysis of defects revealed single acceptor defects significantly impacting solar cell performance in both interfacial and bulk defects. Defect structure simulations demonstrated that increasing doping concentration, decreasing electron affinity, and thickness enhance efficiency. New optimum values for these parameters—1 × 1018 cm-3, 4.0 eV, and 10 nm—yielded Voc: 1.03 V, Jsc: 23.88 mA cm-2, FF: 87.15%, and η: 21.40%. Additionally, a temperature decrease was associated with increased efficiency.

Aluminum metal matrix composite (AMC) is a potential material for diverse applications in the field of automotive and aerospace owing to their superior mechanical properties, lightweight behavior, and low thermal expansion. Graphene nanoplatelets (GNP) have emerged as the preferred reinforcement in AMC. They are incorporated into the matrix by stir-casting methods to generate semi-solid feedstock suitable for thixoforming. The effects of the stirrer parameter and GNP content were examined using Taguchi design of experiments with an L8 (23) orthogonal array. The parameters tested were stirring speed (300-500rpm), GNP content (0.3- 0.7 wt%) and stirring time (5-10 minutes). The signal-to-noise ratio (S/N) and hardness of the GNP /A356 composite were used as response variables. The contribution of three factors in enhancing hardness has been identified. The optimum parameter obtained with stirring speed, GNP content, and stirring time is 500rpm, 0.7wt.%GNP and 5 min respectively.

Almost all buildings in Malaysia were previously designed for non-seismic loading. As such, the need to consider seismic load poses challenges for the engineers and project owners. In order to enlighten the stakeholders on the effect of adopting seismic design, the impact on building material cost and quantities must be investigated in advance. Although many studies have been conducted, the use of hypothetical building models and not considering the actual soil factors in Malaysia may yield unrealistic results. As such, this study is conducted with the aim to evaluate the change in the material quantities of the main frame members using six existing building models subjected to peak ground acceleration of 0.16g and situated on soil type D. The analysis, design and taking-off were conducted with the aid of Tekla Structural Designer software. The results showed significant increase in terms of the material quantity required for the main frame members when seismic design was considered. The increase in the concrete volume and reinforcement tonnage was calculated to be in the range of 6.92% to 404.86% and 3.23% to 563.94%, respectively. The development of high base shear force, the amplification of the seismic force by the soft soil, and relatively stringent detailing in DCM were identified as the contributing factors. With a broader spectrum of results, the stakeholder can anticipate the increase in the material cost for adopting seismic design that can be useful for design submission and project cost estimation.

Kawasan kajian terletak di Kg Ulu Bendol, daerah Kuala Pilah di Negeri Sembilan. Objektif utama kajian adalah untuk mengenal pasti zon sesar menggunakan kaedah geofizik keberintangan elektrik secara protokol Wenner-Schlumberger. Sesar Ulu Bendol, juga dikenali sebagai zon sesar Kuala Pilah, menganjur hampir timur ke barat. Rekod seismik menunjukkan gegaran kecil telah dicetuskan di empat lokasi berhampiran jalan utama Seremban-Kuala Pilah, yang sejajar dengan garisan sesar Ulu Bendol. Kaedah keberintangan elektrik digunakan untuk menentukan lokasi garis sesar secara tepat. Sebanyak 14 garis survei keberintangan elektrik telah dijalankan di 14 lokasi yang dikenal pasti. Batuan granit merupakan unit geologi utama yang menutupi kawasan kajian. Jenis batuan, tahap luluhawa, struktur sesar utama, zon retakan dan kehadiran zon tepu air di bawah permukaan ditentukan berdasarkan tafsiran nilai keberintangan, iaitu granit segar batuan dasar (> 1000 Ωm), granit sederhana luluhawa dan terkekar (500-1000 Ωm), batuan dasar granit terluluhawa dengan batuan yang sangat terkekar (100-500 Ωm) dan zon tepu air dalam batuan yang sangat retak (<100 Ωm). Sesar yang ditafsirkan terletak di kawasan tanah pamah dan dataran dengan nilai kerintangan 100 Ωm hingga 500 Ωm. Sesar yang terletak di Kg. Ulu Bendol, telah menganjur ke timur berhampiran Kg. Mampas, Seri Menanti dengan anggaran kira-kira 10 km. Kajian petrografi ke atas 12 sampel batuan dalam zon sesar menunjukkan bahawa kebanyakan batuan sesar telah mengalami canggaan yang kuat dibuktikan dengan wujudnya mikro sesar, herotan mineral dan kuarza dihancurkan menjadi saiz lebih kecil. Di kawasan zon sesar, sesar yang lebih kecil, juga dikenali sebagai sesar tersegmentasi dengan panjang kira-kira 50 hingga 250 meter, mencetuskan pergerakan berulang sesar utama. Kesimpulan daripada kajian ini menunjukkan kaedah keberintangan elektrik dapat menentukan keujudan sesar utama di Ulu Bendul. Ia boleh digunakan bagi menentukan sesar utama di kawasan lain sekiranya sesar tidak dapat dicerap di permukaan.
Detection of Outliers in Circular Regression Model Via DFBETAcIS Statistic
Authors: Ramlee Intan Mastura , Ibrahim Safwati , Leow Wai Zhe , Yusoff Mohd Irwan
Published: April 2024

The outlier issues in circular regression models have recently received much attention. The presence of outliers may cause the sign and magnitude of regression coefficients to vary, resulting in inaccurate model development and incorrect prediction. Many methods for detecting outliers in a circular regression model have been proposed in previous studies such as COVRATIO, D, M, A, and Chord statistics, but it is suspected that they are not very successful in the presence of multiple outliers in a data set since the masking and swamping is not considered in their studies. This study aimed to develop an outlier detection procedure using DFBETAc statistic for circular cases, where this new statistic will investigate and identify multiple outliers in the Jammalamadaka and Sarma circular regression model (JSCRM) by considering masking and swamping effect. Monte Carlo simulations are used to determine the corresponding cut-off point and the power of performance is investigated. The performance of the proposed statistic is evaluated by the proportion of detected outliers and the rate of masking and swamping. The simulation procedure is applied at 10% and 20% contamination levels for varying sample sizes. The results show that the proposed DFBETAcIS statistic for JSCRM successfully detect the outliers. For illustration purposes, this process is applied to wind direction data.
Invisibility and (Dis)Integration: Examining the Meaning of Migrant Inclusion in Everyday Lived Experience in Rural Areas
Authors: Giannetto Leila , Van der Maarel Shirley
Published: April 2024

The settlement of migrants in rural areas that are facing population decline has gained increased attention in recent years as an economic, social, and political issue, as well as an opportunity for development for local communities. Studies have primarily focused on investigating whether and how migrants are integrated and included within these areas. This article adopts a fresh perspective by examining how the meaning of “integration” and “inclusion” is given shape by residents and migrant workers themselves. Our research centres on a small rural town in Sardinia, where individuals from Romania and West Africa have relocated to fill job positions traditionally held by Italians. Based on participant observation and in‐depth interviews, we examine the everyday experiences of residents and migrants to develop an understanding of the lived realities of integration and inclusion. In doing so, the article calls into question the perceived value of these processes for the very individuals that are supposed to benefit from them.
Transforming Public Spaces in Post-Socialist China’s Danwei Neighbourhoods: The Third Dormitory of the Party Committee of Shandong Province
Authors: Shi Tao , Guo Fangjie , Zhang Yali
Published: April 2024

The urban residential pattern in China experienced two significant transitions during the second half of the 20th century. The first happened in the 1960s, based on the Soviet model, when a large-scale community model was built led by government enterprises and institutions under a planned economy; the second was in 1998 when the real estate market-led socialised community model emerged after the reform of commercial housing. The former is characterised by the integration of supervisory units, service units, and property owners: Residents enjoy the right to use the residences and supporting services provided by their affiliated institutions, while for the latter case, supervisory units, service units, and property owners are separate. New conflicts have been found in Danwei neighbourhoods with the housing commercialisation reform. This research focuses on the Third Dormitory of the Party Committee of Shandong Province as a case study to analyse the transformation of public space in the Danwei neighbourhood during the post-socialist era. Through archival research, interviews, and observation, this research has found that two forces that celebrate marketisation by the new residents and resist marketisation by the original residents coexist in the Third Dormitory. Unregulated spatial practices have resulted from the incomplete control of the owners of public space by the provincial government office. This research offers an example of public space transformations in Danwei neighbourhoods, which have undergone incomplete marketisation. The reflections on the Third Dormitory provide references for future neighbourhood management and policy-making.

Frente al método tradicional de enseñanza que se aplica en los estudios jurídicos, se plantea un enfoque pedagógico de aprendizaje experiencial basado en la problematización jurídica y el uso del Storytelling en los diferentes estudios de caso, con el objetivo de dinamizar la puesta en práctica de los contenidos contemplados en el programa de la asignatura. A través de casos jurídicos que recorren las diferentes etapas vitales de un personaje en la antigua Roma, este modelo narrativo involucra al alumnado haciéndole partícipe en el estudio del caso en un ambiente de participación activa. A la par, el discente profundiza en el manejo de las fuentes romanas durante la resolución de casos aplicando los conocimientos adquiridos en el aula y fomentando así una experiencia educativa enriquecedora y significativa.

Antecedentes del principio de igualdad de género en el ius adcrescendi in partem
Authors: Fernández Vizcaíno Belén
Published: April 2024

En caso de omisión testamentaria de un sui heredes por el paterfamilias el ius civile declaraba la nulidad del testamento si el omitido era un varón, lo que no ocurría si era una hija, que recibía una parte de la herencia paterna, con diferente medida según los instituidos mediante el denominado ius adcrescendi in partem. Con la evolución del Derecho, el pretor favoreció el derecho de las hijas a la herencia de su padre concediéndoles la bonorum possessio contra tabulas, que podía ser más ventajoso patrimonial y procesalmente. Más tarde, la legislación de Justiniano dispuso que la mujer debía ser estimada al igual que el hombre, ordenando que la preterición de una hija tuviese el mismo efecto que la omisión de un filius suus. Esta evolución muestra una adaptación del derecho a la sociedad desde el espíritu de igualdad de trato de los hijos, sin distinción de sexo, lo que podemos considerar un antecedente del principio de igualdad de género.

Authors: Fauziah Silva , Trilaksani Wini , Nurhayati Tati
Published: April 2024

Docosahexaenoic acid (DHA) merupakan asam lemak omega-3 pada minyak ikan yang berperan penting dalam perkembangan otak dan retina. Minyak ikan kaya DHA belum diproduksi secara massal di Indonesia. Mata tuna yang menjadi hasil samping industri perikanan dapat menjadi sumber potensial DHA dan eicosapentaenoic acid (EPA). Minyak mata tuna dengan karakteristik tinggi DHA dan polyunsaturated fatty acid (PUFA) rentan mengalami oksidasi, sehingga proses pemurnian perlu dilakukan untuk menghilangkan pengotor penyebab oksidasi. Penelitian ini bertujuan untuk menentukan perlakuan pemurnian terbaik melalui parameter mutu minyak ikan guna menghasilkan minyak mata tuna dengan penurunan pengotor yang maksimal. Minyak mata tuna diperoleh melalui ekstraksi secara sentrifugasi. Minyak yang dihasilkan selanjutnya dimurnikan dengan beberapa tingkatan perlakuan permurnian, yaitu netralisasi (N1), netralisasi bleaching (N1B1), netralisasi bleaching netralisasi (N1B1N2), dan netralisasi bleaching netralisasi bleaching (N1B1N2B2). Pemurnian menggunakan jenis adsorben yang berbeda, yakni alumina aktif 8%, arang aktif 10%, dan magnesol XL 5%. Parameter yang dianalisis meliputi asam lemak bebas (FFA), bilangan asam, bilangan peroksida, anisidin, dan total oksidasi (TOTOX). Hasil penelitian menunjukkan bahwa perbedaan jenis adsorben dan perbedaan tingkat ekstraksi berpengaruh secara nyata (p<0,05) terhadap bilangan peroksida, bilangan anisidin, total oksidasi, asam lemak bebas dan bilangan asam. Perlakuan dengan tingkat pemurnian N1B1N2B2 dengan adsorben magnesol XL 5% merupakan perlakuan terbaik. Proses pemurnian menghasilkan penurunan paramater oksidasi mencapai 50-80% meskipun minyak yang dihasilkan masih belum sesuai standar.

Suicide, a tragic loss of life, is a complex and multifaceted phenomenon, presenting a significant challenge to public health efforts globally. The prevalence of suicide, particularly due to pesticide self-poisoning in rural areas of low and middle-income countries, underscores its significant impact. Despite efforts to understand suicide, little is known about the diverse range of poisoning agents used and the socioenvironmental factors surrounding their selection.

To study sociodemographic profile, choice of poisoning agent, and self-reported reasons for attempted suicide.

This was a retrospective observational study. All the case records of patients admitted for attempted suicide by oral poisoning in a tertiary care hospital were accessed and assessed in detail regarding sociodemographic profile, choice of oral poisoning agent, and self-reported reasons for attempted suicide.

The present study, comprising 146 cases of attempted suicide, revealed a predominant age group of 18-27 years, with a male majority and a high illiteracy rate. The agricultural sector, low socioeconomic status, and unmarried status were prevalent among the participants. Herbicides were the most commonly used poisoning agents, followed by insecticides. Immediate precipitants for suicide attempts were family quarrels.

The findings of the current study align with previous research, indicating a vulnerable demographic of young, unmarried males from low socioeconomic backgrounds. The predominance of agricultural sector involvement underscores the accessibility of pesticides as suicide agents. Family conflict was cited to be the immediate precipitant for suicide attempt. Thus, addressing underlying sociodemographic stressors and regulating pesticide availability could mitigate suicide risk. Moreover, interventions targeting psychosocial support and coping strategies are crucial for preventing suicide attempts.

This study presents insights into the choice of poisoning agents and self-reported motives in suicide attempts, shedding light on the underlying sociodemographic factors and immediate precipitants driving these behaviours.
