Authors: Карташова А.В. , Винникова Л.М. , Гущина М.Ю. , Деева Л.Д.
Published: September 2023

Рассмотрены наиболее популярные в РФ методики определения бенз(а)пирена в почвах и представлены результаты межлабораторных экспериментов с их использованием. Полученные данные показали недостаточную эффективность процедур извлечения бенз(а)пирена из пробы. Одной из причин занижения результатов может быть потеря бенз(а)пирена в процессе пробоподготовки. Для установления поправочного коэффициента лабораториям необходимы матричные стандартные образцы, отсутствующие на отечественном рынке. Проведенный межлабораторный эксперимент позволил аттестовать образец, который можно использовать для проведения внутрилабораторного контроля, оценки правильности выполнения анализов и улучшения процедур анализа.
Evaluaciones de Lula y Dilma en las élites latinoamericanas: de la transversalidad ideológica a la división
Authors: Bohigues Asbel , Rivas José Manuel
Published: September 2023

El objetivo de este artículo es analizar, con datos de encuestas a legisladores en 16 países de América Latina, los determinantes de las evaluaciones de dos líderes políticos, Lula da Silva y Dilma Rousseff, teniendo en cuenta variables explicativas relacionadas con los atributos sociodemográficos y, sobre todo, con la ideología de los legisladores. Los resultados de las regresiones logísticas muestran que el principal determinante es la valoración de la Alianza Bolivariana para los Pueblos de Nuestra América (alba) y su efecto se reforzó durante la presidencia de Rousseff. Esto se debe a la caída en las evaluaciones positivas en el campo de la derecha, que tenía mejor opinión de Lula. Este texto aporta evidencia empírica de que cuando se trata de evaluar a presidentes latinoamericanos, importa más la ideología que las medidas que estos implementen en sus países. Este hallazgo contribuye a entender mejor por qué algunos liderazgos, como el de da Silva, son ideológicamente transversales.
Las rutas de indefinición y las dimensiones de la cohesión social. La desigualdad como dimensión distintiva
Authors: Del Campo Esther , Hernández Corrochano David
Published: September 2023

Este artículo muestra que el desarrollo teórico, empírico e institucional del concepto cohesión social, ha implicado una elevada ambigüedad que se manifiesta en seis dilemas de indefinición y en un solapamiento entre este concepto y los de comunidad y de capital social. Partiendo de ello, y admitiendo dicha ambigüedad, los objetivos de este trabajo son: 1) localizar las dimensiones definitorias de la cohesión a partir de las variables utilizadas en 54 artículos académicos, 2) vincular los resultados con el modo con que comprenden el concepto los organismos internacionales y 3) poder concluir que la cohesión social se define a partir de ocho dimensiones, que remiten a una doble ecuación de pertenencia objetiva y subjetiva al grupo, y por las que se solapa con la comunidad y el capital social, pero que, además, cuenta con una dimensión diferenciadora: la desigualdad.
El discurso de odio y los límites de la libertad de expresión en Estados Unidos
Authors: Gómez Peralta Héctor
Published: September 2023

El artículo analiza el debate que existe en Estados Unidos sobre los límites y alcances de la libertad de expresión, a la luz de los más importantes casos de la Suprema Corte en la materia. Frente al argumento de que el discurso de odio es una dimensión opuesta a la libertad de expresión y que, por consecuencia, debería de prohibirse, se muestra cómo históricamente la Suprema Corte estadounidense ha defendido la constitucionalidad de expresiones que pueden considerarse ofensivas, degradantes o vulgares. Para diferenciar el discurso de odio de los crímenes de odio, se realiza un análisis histórico de los argumentos de los magistrados de la Suprema Corte.

Published: September 2023

Anaerobic digestion can be a viable alternative for the destination of effluents from stabilization ponds rich in naturally produced microalgae, without the need for concentration processes, however, there are challenges related to the rigid cell wall of microalgae and the low carbon content in its composition, to be overcome. To improve these parameters, this study comparatively evaluated hydrolytic pretreatments in microalgae from effluents from stabilization ponds, aiming to hydrolyze the cell wall of these microorganisms, for co-digestion with residual glycerol from biodiesel. In this case, glycerol is a by-product with limited applicability, acting in this scenario as a carbon supplier, improving the C/N ratio, microalgae biodegradation and biomethane production. Effluents with microalgae submitted to thermal and ultrasonic hydrolysis (for 30 and 90 minutes) were tested to assess their potential in the production of methane-rich biogas, monitored by gauge measurements and gas chromatography, respectively, in co-digestion with residual glycerol from biodiesel. The heat treatment for 30 minutes showed more satisfactory results and was replicated in a benchtop anaerobic reactor (R2), in parallel with a reactor operating untreated microalgae (R1), in a continuous feed system. The effects of pretreatment and COD/N ratio were evaluated on organic matter removal and biomethane production. R2 showed the most satisfactory effect on COD removal, resulting in up to 90% COD removed, with a theoretical biogas production of 0.52 L g-1 COD removed. As for the methane content contained in biogas, R1 reached percentages of up to 84% against 73% in R2.

Published: September 2023

Atualmente, têm se dado maior atenção à contaminação de recursos hídricos por diferentes categorias de compostos, por este se tratar de um recurso essencial à vida. Desta forma, o presente trabalho realizou um estudo bibliográfico referente à síntese de geopolímeros (GPs), através de diversos materiais e metodologias, com aplicação para a adsorção de metais pesados, abordando a questão de modificações realizadas na síntese dos GPs, visando obter a potencialização de suas características de adsorção. Constatou-se que para a síntese dos GPs não há um padrão, ou seja, podem ser usados um número variado de materiais precursores, ativadores alcalinos, tempos e temperaturas de cura, com recipientes selados ou não e optar por diferentes tamanhos de partículas para utilização no processo de adsorção. Também, pode ser feito uso de agentes criadores de poros, ou modificações realizadas durante a síntese dos materiais visando atribuir as características desejadas aos GPs. A utilização de GPs como adsorventes com o objetivo de remover metais pesados, mostrou-se eficaz e com perspectivas de aplicação para diversos íons metálicos (Ni, Pb, Cu, Hg, Cd, Cr, Zn, Cs).

Authors: Sabino Hullysses , Menezes Juliana
Published: September 2023

Water salinization changes hydrogeochemistry, affects the quality and quantity of groundwater available for human consumption and its mitigation is time-consuming. A large brackish lagoon and the Atlantic Ocean surround the aquifer of the São José do Norte town (Brazil). Population and economic growth demand more groundwater for domestic and agricultural purposes, stressing the aquifer. Despise the aquifer’s social-economic status, potential impacts on the groundwater have not yet been substantially investigated. The aims of this study were to analyze the hydrogeochemistry of the São José do Norte aquifer, focusing on the search for salinization indicators, and to assess the groundwater suitability for human drinking and irrigation purpose. Ionic ratios, Piper and USSL diagrams were applied, such as new methods, as Seawater Intrusion Groundwater Quality Index (GQISWI) and the Groundwater Quality Index for human consumption (GWQIHC). The results showed that the groundwater is mostly calcium bicarbonate type and did not indicated salinization occurrence. The interior and the northern area had the highest ionic content and the lowest water quality values. Most of the samples contained at least one parameter above the maximum allowed concentration for drinking purpose according to water quality standards. High concentration of alkalinity, iron and hardness reduced the groundwater suitability for human consumption, requiring water treatment before ingestion.
Comparative Study on Analysis of Losses and Leakage Current for Transformer-less Inverters for PV Applications: A Review
Authors: Imran Mohammed , Mane Manjula
Published: September 2023

Abstract: The reduction in the Common Mode Voltage (CMV) and thermal losses in semiconductors play a crucial role in designing of a new transformer-less inverter topologies for solar powered applications. The galvanic isolation and the leakage current problem due to non-availability of transformer can be addressed either by providing additional switches on the dc side or on the ac side, but this results in more number of semiconductor devices being added into the conduction paths which are switched according to the desired output requirements which further results in high conduction and switching losses indirectly effecting the efficiency of the transformer-less inverters. Hence it is important to study the existing topologies in view of the total losses, CMV and leakage current parameters together. In this review paper H5, H6 and HERIC transformer-less inverter configurations in terms of CMV, Leakage current, Conduction and Switching losses as total losses have been analyzed using PSIM2022.2 simulation software package with the availability of the thermal module. The study of total losses with CMV and leakage current will help in noting the drawbacks of the topologies discussed in this paper.

The lazy economy in a developing country
Authors: Singharat Wanlop , Kraiwanit Tanpat , Shaengchart Yarnaphat
Published: September 2023

The evolution of technology encourages lazy behaviour or addiction to convenience. Consumers are willing to pay for products and services that help them to live a more comfortable life thanks to changes in their behaviour. They want to save time and energy for something else; even if a job is beneficial to them, they would prefer someone else to do it (Komin, 2019). The lazy economy is an intriguing economic trend in today’s world as the market for hyper-convenience is rapidly expanding (Chou, 2019). This study investigated the factors affecting the lazy economy in Thailand. A quantitative approach was employed. An online questionnaire was used to collect data from a convenience sample of 636 participants in Thailand. Binary regression analysis was performed for the data analysis. For online shopping, the lazy economy could be described as being a student, using Facebook, and using Twitter. For catering, the lazy economy could be described by score and education. The development of comprehensive and consistent related laws is required in the next phase to share resources, strengthen community cooperation, create a sense of security and peace of mind, and reduce the gap in the consumption of goods and services in the lazy economy.

Background: In recent years, game-based teaching (GBT) has become
increasing popular in the field of education. Increasingly, teachers are
using game-based methods to facilitate learning activities, though much
experience and time are required to formulate the content and pattern of
study. However, preparing GBT burdens teachers as its tedious steps,
which requires supports to give teacher suggestions during teaching
process. Besides, few studies have developed GBT systems to help
teachers make suggestions for student performance. Objectives: This
study aims to design of a teaching assistant system SmartTA, based on
GBT, automated machine learning, and blockchain, that provides GBT
examples for teachers to consult and suggestions keyed to students’
final examinations and grades. Method: According to meet the
requirements of helping teachers preparing GBT more easily, this

blockchain technology. In order to get the user’s evaluation, several
databases have been applied to evaluate the operation of the system and
have yielded positive results in testing. Results:The results indicated
that this approach could assist teachers in designing GBT, reducing
their preparation time and increasing the quality of their instruction.
SmartTA contributes to the digital transformation of the education
industry by offering critical data analysis, course recommendations, and
secure data storage. Conclusion:The system combines the open and
distributive advantages of blockchain with the data mining and analysis
functions of AutoML, to provide guidance for the deployment of GBT in
the classroom so that doing so is far more efficient. However, this
study also has some limitations. For example, it relys on the electronic
devices, and this factor maybe a disadvantages for someone do not grasp
the technique to use such devices, like children or elders.

OBJECTIVE

To assess anxiety and risk perception among parents whose children screened positive for islet autoantibodies, indicating elevated risk for type 1 diabetes (T1D).

RESEARCH DESIGN AND METHODS

The Autoimmunity Screening for Kids (ASK) study identified 319 children age 1 to 17 years at risk for T1D via screening for islet autoantibodies; 280 children with confirmed islet autoantibodies and their caregivers enrolled in a follow-up education and monitoring program to prevent diabetic ketoacidosis at diagnosis. Parents completed questionnaires at each monitoring visit, including a 6-item version of the State Anxiety Inventory (SAI), to assess anxiety about their child developing T1D, and a single question to assess risk perception.

RESULTS

At the first ASK follow-up monitoring visit, mean parental anxiety was elevated above the clinical cutoff of 40 (SAI 46.1 ± 11.2). At the second follow-up monitoring visit (i.e., visit 2), mean anxiety remained elevated but started to trend down. Approximately half (48.9%) of parents reported their child was at increased risk for T1D at the initial follow-up monitoring visit (visit 1). Parents of children with more than one islet autoantibody and a first-degree relative with T1D were more likely to report their child was at increased risk.

CONCLUSIONS

Most parents of autoantibody-positive children have high anxiety about their child developing T1D. Information about the risk of developing T1D is difficult to convey, as evidenced by the wide range of risk perception reported in this sample.

Laser beam welding of brass with combined core and ring beam
Authors: Maiwald Daniel , Nothdurft Sarah , Hermsdorf Jörg , Kaierle Stefan
Published: September 2023

Brass represents a large part in the production of components within the copper alloy group. Laser beam welding of this alloy offers great potential for many applications in terms of achievable seam quality and productivity. However, there is a very high tendency of the process for irregular seam surfaces and formation of pores as well as spatters. These are due, among other things, to instabilities of the keyhole, which is favored by the evaporation of the alloy component zinc. Furthermore, near-infrared laser beam wavelength can couple poorly into the material due to the low absorption level of brass, whereas absorption jumps during the melt transition. In recent years, high-brilliance near-infrared laser beam sources with adjustable beam profiles have been developed, to contribute to the stabilization of the keyhole. The presented experimental process investigations are on deep penetration welding of different brass alloys (CuZn37 and CuZn39Pb3). A laser beam source with a power of 6000 W and a combined core and ring beam was used for this purpose. It was found that the process parameters, such as energy per unit length, spot size, and process gas supply, have a significant impact on the resulting weld seam. These parameters were systematically varied. The produced seams were analyzed and evaluated using various methods, including micrograph analysis, energy dispersive x-ray spectroscopy, 3D-computed tomography, and 3D-topography imaging. The results were then correlated with the process parameters. Process parameters that produce high-quality bead-on-plate and butt welds for a sheet thicknesses of 2 mm were determined.

Authors: Kobune Hiroto , Kubo Yoshiaki , Fukuda Yasushi , Matsuura Yuto , Kato Takeyuki , Koyama Koji
Published: September 2023

Foam rolling (FR) is an easy-to-perform self-care activity to improve the range of motion in patients with injuries. However, even if FR is performed at the same intensity, the feeling differs depending on the patient. In addition, FR affects the contralateral side. This phenomenon is called cross education. Therefore, the main purpose of this study was to examine the relationship between FR sensitivities and FR efficacy. The secondary purpose was to determine how FR intensity perception influences cross education. In this study, FR sensitivity was calculated using the Visual Analogue Scale (VAS). The difference in the effect of FR sensitivity was evaluated using the correlation between the amount of change in PRE-test to POST- test ROM and VAS. The experimental procedure in this study first measures ankle dorsiflexion range of motion (ROM) on the left and right leg. Immediately after measurement, 3sets of FR were performed on one random leg. Participants wrote the VAS of FR for each set during the rest period of each FR intervention set. Immediately after 3 sets of FR, the ROM was measured in the left and right legs. Statistical analysis performed Two-way repeated measures ANOVA in group comparison. As a result, two-way ANOVA did not show a significant effect of group (F = 0.003, P = 0.95) or interaction effect (F = 2.28, P = 0.14). In contract, time had a significant effect (F = 39.65, P = 0.001). Post hoc result in [Dominant leg] PRE: 19.7 ± 7.6° POST: 22.2 ± 7.3° P = 0.001 Δ = 0.33. [Non-dominant leg] PRE: 20.0 ± 7.8° POST: 21.6 ± 7.8° P = 0.01, Δ = 0.21). On the other hand, Pearson’s correlation coefficient was used for the correlation between the amount of change in ROM and VAS. As a result, a dominant leg significant negative correlation was observed between the 3dr set of FR VAS score and the amount of change in ROM (r = -0.38, P = 0.04). Non-dominant leg significant correlations were observed third set of FR VAS score and amount of change in ROM (r = 0.41, P = 0.03). The result of this study suggested that it is necessary to perform FR with a comfortable stimulus on the dominant leg to maximize the effect of FR.

Published: September 2023

Kemampuan bersaing hasil produksi gula merah yang dikerjakan dengan sangat tradisional semakin hari semakin menurun, hal ini juga terjadi hasil produksi gula merah pada kelompok petani gula merah yang tergabung pada Gapoktan Gunung Sari Desa Gunaksa, Klungkung, Bali. Ketidakmampuan bersaing dapat dibuktikan melalui semakin berkurangnya anggota kelompok Gapoktan dari tahun ke tahun. Masuknya gula merah dari berbagai wilayah dengan harga yang lebih terjangkau, menyebabkan hasil produksi gula merah Gapoktan Gunung Sari tidak mampu dijual dengan harga yang lebih tinggi. Hal ini menyebabkan, anggota kelompok petani gula banyak yang berhenti membuat gula. Pengabdian saat ini berupaya mempertahankan daya saing, dengan meningkatkan nilai tambah produk berupa mengubah bentuk cetakan gula (re-design), pengemasan (packing), dan pemberian label/merek (labelling). Pengabdian dilakukan melalui pendekatan ceramah dan peragaan peningkatan nilai tambah melalui perubahan bentuk, pemberian pembungkus dan label pada produk. Anggota kelompok sangat antusias mengikuti kegiatan pengabdian ini. Pengabdian kali ini diharapkan mampu memotivasi anggota kelompok tani untuk tetap menggeluti usaha pembuatan gula merah.

Namun sering kali RPS dan bahan ajar yang dikembangkan belum sesuai dengan Kerangka Kualifikasi Nasional Indonesia (KKNI). Penelitian dan pengembangan ini bertujuan untuk menghasilkan RPS dan buku ajar kimia bahan pangan yang sesuai dengan tuntutan KKNI. Model pengembangan buku ajar yang digunakan adalah model ADDIE (Analysis > Design > Development > Implementation > Evaluation) namun pada penelitian ini hanya sampai tahap development. Teknik pengumpulan data menggunakan wawancara dan instrumen analisis RPS dan BSNP. Data yang diperoleh berupa data kuantitatif dan kualitatif. Uji kelayakan dilakukan oleh ahli materi dan ahli pengembangan. Komentar, tanggapan dan saran yang diberikan digunakan untuk merevisi dan memperbaiki RPS dan buku ajar yang dikembangkan. Hasil penilaian kelayakan oleh para ahli menunjukkan RPS dan buku ajar sudah sangat layak digunakan untuk proses perkuliahan kimia pangan

Objectives: Nickel is one of the common trace metal element used in industries. It has been documented that even in small quantities, prolonged exposure to nickel is cytotoxic, genotoxic and carcinogenic. Nickel biomonitoring has been done by various countries to monitor nickel level. However, there is little information on established baseline nickel level in our population which leads to the difficulty for comparison during nickel exposure. This study aims to determine the baseline nickel level in saliva and urine samples for the healthy Malay population. Materials and Methods: Fourteen healthy Malay subjects were recruited in this study. Saliva and urine samples were collected and analysed using Inductively Coupled Plasma Optical Mass Spectrometry (ICP-MS) to measure the nickel level. Statistical analysis was performed using IBM SPSS Version 27. Results: Results showed that the nickel level in urine was higher compared to saliva. The baseline nickel level exhibited in saliva was 4.80 ppb (95% CI: 2.23, 7.38) and in urine was 5.88 ppb (95% CI: 3.49, 8.27). Conclusion: To our knowledge, this is the first study to report the baseline nickel level in saliva and urine among the Malay population.

Background: Human periodontal ligament stem cells (PDLSC) are multipotent cells, derived from periodontal ligament (PDL), that can attain the formation of new bone, cementum, and periodontal ligament. However, the quantity of stem cells found in PDL tissues is deficient. Therefore, in periodontitis, the limited PDLSCs make regeneration of the periodontium challenging and unpredictable. Objectives: To critically appraise the available experimental evidence of the local immunomodulation signaling systems and their surrounding functional molecules for repair and application in periodontal regeneration therapy. Methods: This systematic review was conducted using PRISMA 2020 guidelines and research papers were selected based on strict exclusion and inclusion criteria. PubMed, Cochrane Library, Google Scholar and Web of Science databases were used to collect all the research papers ranging from January 2012 to December 2022. Results: Nine out of 586 research papers that focused on PDLSCs during inflammatory conditions were selected based on the Cochrane Risk of Bias Assessment. Seven articles documented that non-coding microRNAs (ncRNAs) played critical roles in the modification of PDLSC multipotency in periodontitis. An article showed that the post-translational modifications are influenced by histone deacetylases (HDAC) indicating the involvement of novel epigenetic signaling systems. A natural product-derived functional molecule resveratrol is described to have anti-inflammatory properties through the nuclear factor kappa B (NF-kB) pathway. Conclusion: The results of our present systematic review clearly apprise that the ncRNAs signaling system and natural products derived anti-inflammatory functional molecules play a clinically significant therapeutic target in novel periodontitis therapy as preventive, diagnostic, therapeutic, and prognostic markers.

Introduction: Idiopathic Trigeminal neuralgia in children is a rare case presentation that poses a challenge in dental practice. This case involved a sequence of multi-management by several departments including Paediatric Dentistry, Oral Maxillofacial Surgery (OMFS), Otorhinolaryngology (ORL) and Paediatric Neurology. Case description: A 10-year-old girl was referred initially to the Paediatric Dentistry Specialist Clinic, School of Dental Sciences, Universiti Sains Malaysia (USM), Malaysia with the complaint of left facial pain associated with muscle twitching, weakness and swelling for five days prior to this first visit. There was a history of tooth extraction of her lower left second primary molar on the day before the episode of left facial pain and twitching. Clinical examination showed left facial involuntary twitching with visual analogue scale (VAS) pain score of 8, some evidence of left facial weakness, numbness but no facial swelling. No significant finding on the intraoral examination, including good healing signs at the exodontia site. The investigations included orthopantomography, Cranial Nerves II-XII examination and tests, blood investigations, Blood Urea and Serum Electrolyte (BUSE), electromyography (EMG) and electroencephalogram (EEG). The final diagnosis was left Idiopathic Trigeminal Neuralgia that is associated with tooth extraction. After a period of a month, the symptoms and signs were gradually reduced and ceased by taking oral medications such as Baclofen, Neurobion and Gabapentin. Joint management from multi-departments with close follow ups help to provide the conservative and safe treatment for this patient.

The purpose of brand positioning is to change the perception of prospective customers compared to other brands in the same product category. Many business organisations try to steer the customer's mind on the target brand and its advantage in the market. To determine whether the positioning of a certain brand is a success or not, a company should observe whether its brand is salient or not to the customers. Positioning or brand positioning includes choosing a particular product characteristic from the whole set of features associated with the brand. The main aim of this research is to determine the factors influencing the brand positioning of three-star hotels among residents in Kuala Terengganu. The first objective is to examine the relationship between the price and brand positioning of three-star hotels. The second objective is to determine the effect of brand image on the brand positioning of a three-star hotel. The third objective is to define the value of the brand positioning of a three-star hotel. The researcher disseminated 384 sets of questionnaires to 384 respondents in Kuala Terengganu and used SPSS version 20 to analyse the data. By using the data gathered, the researchers can produce frequency analysis, descriptive statistical analysis, Pearson test correlation analysis, regression analysis, hypothesis testing, and also the interpretation of objectives. The finding shows that two independent variables (price and brand image) have a significant relationship with the brand positioning of three stars hotels. Brand image is the vision of hotels in the industry more than what hotels' records show and the price represents the standard of service as perceived by the customers. Positioning is the use of marketing to project differentiation in the hotel and its services to targeted customers. Building and maintaining a strong brand positioning is critical in that it will help create a positive image and create unique perceptions among present and potential customers. A hotel with a positive brand positioning will transform a satisfied customer into loyal guests.
