The Grad-Shafranov (GS) equation is a fundamental tool extensively used in plasma physics, particularly in the context of magnetic confinement, notably in tokamaks for fusion energy research. This equation plays a crucial role in reconstructing magnetic field topology in plasma regions like the magnetopause and magnetotail, leading to the development of the GS reconstruction technique. In this third installment of our series, we explore the merger of the Yoon-Lui-2 and Yoon-Lui-3 generating functions, allowing for a deeper understanding of the core equation in Plasma Physics. Furthermore, this article provides a comprehensive summary of solutions previously presented in Parts 1 and 2. We investigate the behavior of magnetic islands positioned above either the X-axis or the Z-axis for specific parameter values and their impact on plasma confinement. The article concludes that the derived model offers a simpler, more stable, and easily analyzable solution for magnetic morphology. However, it is worth noting that the model’s inflexibility in singularity positions may limit its adaptability to different scenarios. This article marks the conclusion of our physics education series dedicated to studying new specific solutions of the GS equation.

Abstract The present study evaluated the hematological, antiparasitic and growth responses in tambaqui (Colossoma macropomum) fed with diets supplemented with the microalgae Arthrospira platensis and Chlorella vulgaris (0%; 10% A. platensis; 10% C. vulgaris; and 5% A. platensis+5% C. vulgaris). Tambaqui (n=60, 62.57 ± 8.76 g) were fed for 20 days with experimental diets. Blood samples collection was done to determine hematological parameters, and gills were removed to identify and count monogenetic parasites. Supplementation with A. platensis 10% reduced red blood cells count, in consequence mean corpuscular volume and mean hemoglobin concentration increased. Total leukocyte, monocyte, eosinophil, and basophil counts reduced with the use of A. platensis. Higher monocytes, eosinophil, and basophil numbers in tambaqui fed with diet supplemented with 10% C. vulgaris were observed and may have been due to the presence of immunostimulants in this microalga composition. Reduction on total cholesterol in tambaqui that received both microalgae (A. platensis 5%+C. vulgaris 5%) may indicate that combined supplementation presented greater benefits to the health for C. macropomum than separately. Both microalgae were efficient against monogenetic parasites of tambaqui. Thus, the dietary use of the microalgae A. platensis and C. vulgaris provided immunostimulant and antiparasitic efficacy in C. macropomum.

Resumo O presente estudo avaliou as respostas hematológicas, antiparasitária e de crescimento de tambaqui (Colossoma macropomum) após alimentação com dietas suplementadas com microalgas Arthospira platensis e Chlorella vulgaris (0%; 10% A. platensis; 10% C. vulgaris; e 5% A. platensis+5% C. vulgaris). Exemplares de tambaqui (n=60, 62,57±8,76 g) foram alimentados por 20 dias com as dietas experimentais. Amostras de sangue foram coletadas para determinação dos parâmetros hematológicos e brânquias foram retiradas para contagem de parasitos monogenéticos. A suplementação com A. platensis 10% reduziu o RBC, consequentemente aumentando os valores de VCM e HCM. As contagens de leucócitos (total) e de monócitos, eosinófilos e basófilos reduziram com o uso de A. platensis. Números altos de monócitos, eosinófilos e basófilos em tambaqui alimentado com dietas com 10% C. vulgaris foram observados e podem ter ocorrido devido à presença de imunoestimulantes na composição da microalga utilizada. Redução dos níveis plasmáticos de colesterol total em tambaqui indicou que a inclusão das duas microalgas (A. platensis 5%+C. vulgaris 5%) pode indicar que maiores benefícios à saúde do peixe do que quando separadamente suplementada. Ambas mostraram eficácia contra parasitos monogenéticos das brânquias de tambaqui. Assim, conclui-se que o uso das microalgas C. vulgaris e A. platensis promovem ação imunoestimulante com eficácia antiparasitária em C. macropomum. hematológicas Colossoma macropomum 0% 0 (0% 10 C 5 platensis5 platensis+5 vulgaris. . vulgaris) n=60, n60 n 60 (n=60 6257876 62 57 8 76 62,57±8,7 g 2 experimentais RBC HCM (total monócitos utilizada (A 5C 5%+C suplementada Assim concluise conclui se (0 1 platensis+ n=60 n6 6 (n=6 625787 7 62,57±8, ( n=6 (n= 62578 62,57±8 n= (n 6257 62,57± 625 62,57 62,5 62,

Given the extensive use of pesticides in modern times, residues are frequently detected in water samples. Therefore, this study developed and validated a method utilizing solid-phase extraction (SPE) with a polymeric sorbent for sample preparation in combination with ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS). The aim was to determine a variety of current-use pesticides (CUPs) in different types of water. The preconcentration step, employing the polymeric sorbent Oasis HLB (60 mg), combined with the high selectivity and sensitivity of the UHPLC-MS/MS analysis, enabled the multiclass determination of pesticide residues in water samples at very low concentrations. The proposed method underwent validation, demonstrating satisfactory linearity, precision, and accuracy. The accuracy results, determined through recovery assays at varying spike levels (0.04-0.4 μg L-1), ranged from 71 to 117%, with precision expressed as relative standard deviations consistently below 19%. The practical limits of detection and quantification for most compounds were 0.01 and 0.04 μg L-1, respectively. This method was effectively employed to analyze drinking water, artesian well water, dam water, and river water, leading to the detection of various pesticides at concentrations of up to 2.24 μg L-1. times Therefore solidphase solid phase SPE (SPE ultrahigh ultra UHPLCMS/MS.

This article provides a comprehensive review of relevant studies in the fields of plasma physics, electromagnetism, and space physics. The aim is to demonstrate how the study of the scientific literature can be used to enhance problem-solving abilities and develop innovative solutions in physics. In this paper, we focus on the study of solutions of the specific Grad-Shafranov equation. Two of the new solutions proposed by Yoon and Lui (2005) are used as a basis for the development of a new solution. The new solution presented has singular points similar to the Yoon-Lui-2 solution, but with an inverted configuration, and also presents less rounded double islands compared to the Yoon-Lui-2 solution. Additionally, the new solution does not exhibit the formation of a current ring, a characteristic of the Yoon-Lui-1 solution, and varying its parameters may lead to higher plasma confinement efficiency. In summary, we illustrate how a thorough analysis of literature can serve as a powerful means for generating innovative approaches to resolving theoretical issues in physics. physics electromagnetism problemsolving problem solving paper GradShafranov Grad Shafranov equation 2005 (2005 YoonLui2 YoonLui 2 Yoon-Lui- configuration Additionally ring YoonLui1 1 efficiency summary 200 (200 Yoon-Lui 20 (20 (2 (

In part 1 of our physics education series, we introduced a novel solution based on Yoon-Lui’s solutions 1 and 2. Building upon that, this follow-up presents a new solution obtained by combining the generating functions of Yoon-Lui-1 and Yoon-Lui-3, resulting in a new and simplified general solution. We also calculate the singular points and determine their coordinates for various parameter values. A graphical representation of the solution is presented, showing the magnetic field lines and current density distribution. The behavior of the magnetic field and the effect of varying the parameter are discussed. The observed magnetic islands and singular points are relevant in the fields of Plasma Physics and Space Physics, providing insights into magnetic structures in plasmas and their impact on confinement and stability. Furthermore, this study encourages innovation and equips researchers and students with the necessary tools to make meaningful contributions to the field, emphasizing the integration of scientific literature into physics education to promote a comprehensive understanding of physical concepts and their practical applications. series YoonLuis Yoon Lui s 2 that followup follow up YoonLui1 YoonLui Yoon-Lui- YoonLui3, YoonLui3 3, 3 Yoon-Lui-3 values presented distribution discussed stability Furthermore applications Yoon-Lui

Citrus sudden death (CSD) is a disease that has affected millions of orange trees in Brazil, leading to economic losses in the order of billions of US dollars. This article examines the effects of CSD on the fatty acid composition of triacylglycerides (TAG) extracted from rootstock and scion bark. The fatty acid profile determined by gas chromatography showed a reduction in oleic and linolenic acids, and an increase in the saturated fatty acids and linoleic acid content, which was in line with the severity of CSD. The reduction in linolenic acid content was related to its role in the biosynthesis of jasmonic acid, which is involved in responses to abiotic and biotic stresses, as well as senescence. These alterations in the fatty acid profile were also used to classify plants both with and without CSD symptoms by using chemometric means. This method represents an alternative to support the diagnosis of CSD disease.

RESUMO Parasitas gastrointestinais são importantes, pois podem causar uma diminuição no desempenho dos suínos. A ocorrência de parasitas em granjas de suínos pode gerar perdas econômicas, como redução no valor das carcaças e aumento de gastos com medicamentos e assistência veterinária. Este estudo teve como objetivo investigar a ocorrência de parasitas intestinais nas diferentes fases de produção de suínos criados em sistemas intensivos, na região oeste do estado de Santa Catarina. Foram analisadas 403 amostras fecais, das quais 51,86% foram positivas para um ou mais parasitas nas diferentes fases de produção. Os suínos de terminação apresentaram a maior prevalência de parasitas (60,19%), seguidos por suínos de creche (55,44%), suínos em gestação (50,49%) e leitões em lactação (40,81%). Parasitas da ordem Strongylida tiveram maior ocorrência (28,78%) e também foram os mais frequentes nos estágios de terminação, reprodução e creche. Coccídios foram mais ocorrentes em leitões lactentes. Este estudo destaca a necessidade de implementar medidas de controle antiparasitário adequadas em todas as fases da produção suína, associadas a um sistema de vigilância para o diagnóstico de infecção por endoparasitas em suínos. Os resultados demonstram que os endoparasitas são altamente ocorrentes em suínos, mesmo em animais de criação intensiva em granjas tecnificadas.

ABSTRACT Gastrointestinal parasites are important, since they can cause a decrese in the performance of swine. The occurrence of parasites in pig farms can create economic losses such as reduction in the value of carcasses and increasing expenses with medicines and veterinary assistance. This study aimed at investigating the occurrence of intestinal parasites in different phases of production reared pigs in intensive prodution systems in the western region of the State of Santa Catarina. A total of 403 fecal samples were analyzed, of which 51.86% were positive for one or more parasites in different phases of production. Finishing pigs had the highest prevalence of parasites (60.19%) followed by nursery pigs (55.44%), pigs in breading sows (50.49%), and suckling piglets (40.81%). Strongylida parasites had higher occurrence (28.78%), and were also the most frequent in the finishing, breading sows, and nursery phases. Coccidia were more occurrent in suckling piglets. This study highlights the need of implementing suitable antiparasitic control measures in all phases of swine production associated with a surveillance system for the diagnosis of endoparasite infection in pigs. Our results demonstrate that endoparasites are highly occurring in pigs, even in intensive system animals on technified farms.

RESUMO Amostras do lenho de Araucaria angustifolia foram coletadas em Fazenda Rio Grande/PR (25°39 'S 49° 18 'O) em janeiro de 2011. As 32 amostras provenientes de 8 árvores foram submetidas a tratamentos seguindo as técnicas de dendrocronologia. Os núcleos foram medidos e contados usando-se metodologia óptica e computacional, sendo então padronizados para se obter a série temporal de anéis de crescimento do período 1907-2009, que representa o local de estudo. Índices de anéis de crescimento foram analisados e correlacionados com variáveis climatológicas (temperatura eprecipitação, ambas de 1961-2009). Este procedimento teve o objetivo de estudar e compreender a influência do clima local no crescimento das plantas e se esta influência pode ser quantificada. As árvores de A. angustifolia possuem anéis de crescimento visíveis com lenho inicial e lenho tardio bem definidos. As análises deste estudo mostram que A. angustifolia é sensível ao clima e que as baixas temperaturas no inverno interrompem sua taxa de crescimento. A correlação dos anéis de crescimento com a série mensal de precipitação mostrou tendência de crescimento comum entre elas, o que tornou possível estimar o comportamento sazonal da precipitação durante o período 1907-2009 por meio da reconstrução.

ABSTRACT Samples of Araucaria angustifolia were collected at Fazenda Rio Grande, Paraná, Brazil (25°39'S 49 18'O) in January 2011. The 32 samples from 8 trees were subjected to treatments following dendrochronological techniques. The cores were measured and dated using optical and computational methodology, and then standardized to obtain a growth-ring time series, which considers the 1907-2009 time range and represents Fazenda Rio Grande. Tree-ring indices were analyzed and correlated to temperature and precipitation averages from the 1961-2009 range. This procedure aimed to study and understand the influence of the local climate on the plant growth and if this influence can be quantified. A. angustifolia trees produce visible annual growth rings, and their earlywood and latewood are clearly defined. The present study shows that A. angustifolia is sensitive to climate variables (e.g., low temperatures in wintertime tend to stop the growth rate). The correlation between tree rings and monthly precipitation series showed a common trend, making it possible to estimate the seasonal rainfall behavior for the entire 1907-2009 range.

In this study the immobilization of lipase in matrices produced with gelatin with different Bloom values and with the addition of plastifiers was investigated to evaluate the influence of the Bloom value, as well as the capacity of the plastifiers to maintain the enzyme immobilized and the immobilization yield. The results indicated the need for crosslinking of the matrices with glutaraldehyde due to the high solubility in water, explained by the amino acid profile, which confirms the solubility of gelatin. Mannitol showed greater efficiency in the lipase immobilization, since it led to more porous structures and more uniform pores. These structures were also influenced by the gelatin concentration; greater concentrations associated with intermediate concentrations of plastifier led to matrices with a greater immobilization yield (87.92%). The X-ray diffraction analysis revealed that the structure of the immobilization matrices was partially crystalline.

The aim of the study was to synthesize the urea (13CO(NH2)2), with 99% 13C atoms, and to perform a quality analysis for the diagnosis (breath test) of Helicobacter pylori. Furthermore, the process was submitted to economic analysis. The reaction was performed in a stainless steel reactor, lined with polytetrafluoroethylene, under low pressure and temperature. The synthesis method was shown to be appropriate (2.35 g; 81.9% yield), evidenced by physico-chemical and microbiological results, according to Brazilian legislation. The production and diagnosis costs were competitive compared with national and international market values, rendering this a valuable tool in clinical medicine.
