Superconducting compound Pb2-xHgxBa2-ySry Ca2 Cu3 O10+δ was pressurized (8 tons) using a hydraulic press for different compensation ratios x=(0-0.1-0.2-0.3-0.4./cm2). The prepared sample was put into an electric furnace, and the temperature was raised from room temperature to (600°C) at a rate of (120°C/h), and then the sample was kept at this temperature for (12) hours, and then the furnace temperature was increased at (120°C/h) h) from (600 °C) to (800 °C) and maintained at this level (24 h) in an oxygen-saturated atmosphere and then at a rate of (30 °C/h) from (800 °C) down to (600 °C) and hold at that temperature for (12) hours ،Thereafter, the temperature was lowered from (600° C.) to room temperature at a rate of (30° C./h), and when the synthesis of the compound was completed in X-ray diffraction XRD, laser light was irradiated. Experiments have shown that the results before laser exposure are best compensated. The ratio is x=0. If the compensation ratio of Y is increased to 0.2, its value and regularity increase with the size (c), a = b = 5.471 (A°), c = 34.683 (A°). The increased regularity we observed in the crystal structure of the compound, the compound played better in the crystal structure.Whereas after irradiating and increasing the scale and increasing the compensation ratio to 0.2, the value and regularity increase with increasing dimensionality (c) a = b = 5.479 (A°), c = 34.731 (A°) we note a If we increase the compensation percentage and make the compound play better in the crystal structure, we can improve the regularity of the crystal structure of the compound.Checking the electrical properties of the resistance test, the results show that when the compensation ratio also increases the critical temperature of the junction, the optimal compensation ratio before laser irradiation is x = 0.2, so the critical temperature is (K135). This result can explain that the compound plays an important role in the structure and crystal structure, but the critical temperature after laser irradiation is the same (140 K

Published: June 2023

Since late 17th century Don Pierre Perignon used cork stoppers for his champagne, this material uses as closure were extended for both wines and sparkling wines. Cork has unique and different qualities that, have not yet been imitated or improved, among which we can highlight the combination of lightness, elasticity, high coefficient of friction, impermeability, high calorific value, low water content, good thermal insulation but above all, it is a 100% natural, recyclable and renewable material, witch are today essential attributes for a society committed to reducing pollution and sustainable with the environment. That is why, although new closures have been developed last years (crown cap, screwcap, ...) as well as new materials (synthetic closures), cork is still the most used closure in wine sector. Ccork stoppers have evolved with the developing of different granulometries (natural stopper of one, and two pieces, agglomerated stoppers, microgranulates, stopper 1 + 1, ...) and qualities, influencing considerably both the cost and the final result of the product. Each of these products has different manufacturing processes and different sources and levels of use of raw materials, despite being all manufactured with cork. The knowledge of the characteristics and resources invested in the manufacture of these plugs becomes necessary to carry out an adequate characterization and selection according to the characteristics and typologies of the wines for which they will be used.

Objective: Analysis of prenatal samples from 2015 to 2020. Comparison detection rates of clinically relevant variants by cytogenetic karyotype analysis and cytogenomic MLPA (Multiplex Ligation-Depent Probe Amplification) and microarray methods (CMA – chromosomal microarray). Material and method: 1,029 prenatal samples were analyzed by cytogenetic karyotyping (N = 1,029), cytogenomic methods – MLPA (N = 144) and CMA (N = 111). All unbalanced changes were confirmed by MLPA or CMA. Results: From the analyzed set of fetuses, after subtraction of aneuploidies – 107 (10.40%, N = 1,029), 22 structural aberrations (2.39%, N = 922) – nine unbalanced changes (0.98%), 10 balanced changes (1.08%), one case of unclear mosaicism (0.09%), one case of presence of a marker chromosome (0.09%) and one case of sex discordance (0.09%) – were detected by karyotype analysis. A total of eight (7.21%, N = 111) pathological variants were detected by CMA in 255 samples with physiological karyotype indicated for cytogenomic examination. Five (3.47%, N = 144) of eight pathogenic variants were detected by MLPA method. The total capture of pathogenic variants by MLPA and CMA methods was 14 (5.14%) and 17 (6.25%) (N = 272), including confirmatory pathological karyotype testing. Detection of pathological variants in the isolated disorders group was lower than in the multiple disorders group (5.08 vs. 21.42%). Conclusion: A higher success rate for the detection of pathological copy number variation variants by the microarray method than by the MLPA method was confirmed. Key word: congenital developmental disorders – CMA – MLPA – copy number variants

Background: Examination for the presence of diastasis of the rectus abdominis muscle and examination of the entire posture is very important in postpartum women. Currently, examination by 2D ultrasound, caliper and palpation is used. It is examined at rest and during stress tests. Methods: Case study of a patient with diastasis of the direct abdominal muscle after a fi rst spontaneous uncomplicated delivery at the age of 32 years. Examination to confirm diastasis of the rectus abdominis muscle – the width of linea alba was measured with a 2D linear probe by ultrasound 4.5 cm above the umbilicus, in the region of the umbilicus and 4.5 cm below the umbilicus. Lying on the back at rest, and with elevation of the lower limbs. The degree of severity was classified into four grades. A standard physiotherapy postural examination was performed. A part of the intervention was individual exercise with activation of the m. transversus abdominis to reduce diastasis of the direct abdominal muscles. The exercise program included postural adjustment, modification of breathing stereotype and quality, and activation of pelvic floor muscles. Exercises to reduce pain in the ligamentous apparatus and training in correct ergonomics were also performed. The dosage of exercise was 15 min per day in the 1st week of treatment, 2–4 week of treatment 20 min per day, 5–12 week of treatment 30 min per day, 5 days per week, for 12 weeks. Conclusion: The effect of exercise with activation of m. transversus abdominis on the reduction of diastasis of the direct abdominal muscle in the postpartum patient was objectively proven by the above mentioned objectification methods. Key words: exercise – diastasis of the rectus abdominis muscle – objectification

Published: June 2023

Objective: Review of recent literature dealing with the effect of antipsychotic use during pregnancy on early postpartum adaptation of exposed infants and the development of congenital malformations. Results: The use of antipsychotics during pregnancy does not appear to lead to significantly higher risk of congenital malformations but may pose a greater risk for the early adaptation of the newborn (especially the risk of preterm birth and intensive care unit admission). The study to date face methodological limitations – lack of information on exact doses of antipsychotics, lack of control groups of women with psychiatric problems but not taking antipsychotics and failure to control for confounding factors. Conclusion: The available data suggest the relative safety of antipsychotics during pregnancy, provided that potential risks are known, and the woman and her baby are carefully monitored. Key words: pregnancy – childbirth – antipsychotics – congenital malformation – newborn

Os estudos sobre os processos de institucionalização de demandas, recursos de atuação, valores e categorias dos movimentos sociais no Estado, bem como das capacidades estatais produzidas nesses processos, têm ganhado cada vez mais destaque, seja na Ciência Política, na Sociologia ou na Antropologia. Diversos conceitos e ferramentas analíticas têm sido desenvolvidos e/ou reatualizados com o objetivo de analisar de maneira complexa os fenômenos correspondentes à institucionalização dos movimentos sociais, notadamente a transformação de suas demandas e projetos em políticas públicas, a institucionalização do acesso de atores de movimentos ao Estado, e o reconhecimento desses atores como intermediários legítimos de determinados grupos sociais. Dentre diversos conceitos e perspectivas analíticas avançadas no debate nos útlimos anos, no país, está aquela centada nos ‘encaixes institucionais’ e ‘domínios de agência’, inscrita na tradição do neoinstitucionalismo histórico e informada por uma perspectiva centrada na mútua constituição entre atores sociais e Estado.  A difusão e usos destes conceitos mostraram não apenas ganhos analíticos, mas também ambiguidades, insuficiências e questões não tematizadas na proposta original. O objetivo desta entrevista com os autores dessa abordgem é, à luz das lacunas detectadas em um levantamento de usos na literatura, aprofundar o entendimento teórico da abordagem dos encaixes institucionais e de domínios de agência, e suas possíveis aplicações na pesquisa empírica.

O Programa Inovar Auto e o alcance da igualdade de competição frente às cláusulas da nação mais favorita e do tratamento nacional da Organização Mundial do Comércio
Authors: Wieira Keite
Published: June 2023

O Programa Inovar Auto, iniciativa do governo federal para estimular a indústria brasileira, foi julgado pelo Órgão de Solução de Controvérsias (OSC) da Organização Mundial do Comércio (OMC) para avaliar a compatibilidade com a aplicação das cláusulas da Nação Mais Favorecida (NMF) e do Tratamento Nacional (TN) que estabelecem a igualdade de competição pretendida pelo sistema multilateral de comércio. Assim, o objetivo geral dessa pesquisa consistiu em descrever o julgamento desse caso, a partir dos seguintes objetivos específicos: abordar a industrialização automobilística brasileira e o Programa Inovar Auto; compreender o alcance das cláusulas da NMF e do TN; e, averiguar a aplicação das normas citadas no caso Inovar Auto. A pesquisa desenvolveu-se à luz da interpretação da OMC em relação à implementação das medidas de isenção e redução de barreiras tarifárias na indústria automobilística brasileira. No que tange à metodologia, tratou-se de pesquisa pura e qualitativa. O método de abordagem foi indutivo-crítico. Quanto aos fins, a pesquisa foi descritiva. Os procedimentos técnicos utilizaram doutrina de reconhecidos autores, jurisprudência e documentação da OMC. Em relação ao método de interpretação foi lógico-gramatical. A conclusão indicou que a igualdade de competição pretendida pelo sistema multilateral de comércio, impôs às empresas brasileiras severa limitação no caso do Programa Inovar Auto. Com isso, o princípio da reciprocidade para e entre os países revelou-se uma falácia, em virtude de inexistir diferenciação entre membros marcadamente diversos e em distintos níveis de crescimento econômico, em que pese a intenção das cláusulas da NMF e do TN.
Romance, Suspense, and Translations
Authors: van Dalen-Oskam Karina
Published: June 2023

Translations were usually valued slightly less than Dutch originals.
Participants attributed the lowest mean scores for literary quality to E.L. James’
Fifty Shades of Grey. The Dutch publisher marketed the translations of the Fifty
Shades trilogy as Literary novels. To find out if this label indeed suits the novels
best, the chapter applies cluster analysis using Burrows’ Delta and principal
components analysis (PCA). The same methods are used to explore five novels by
Swedish author Henning Mankell, to see whether the style of his Literary novels
differs from his Suspense novels. Finally, keyword analysis is applied to get an
indication of the fluency of translations, to see whether the results may explain
the differences in ratings of originals and translations.
Our Lady of Contingency
Authors: Blanco John D.
Published: June 2023

This chapter examines the proliferation of devotional cults to the
“Virgin Queen” Mary against the absence of Crown authority in the provinces
in order to highlight the imaginary character of the unfinished conquest and
its “spiritual” continuation. The proliferation of devotional cults owed itself
to not only the religious ministers but also the participation of Indians in the
organization and enactment of paraliturgical traditions like town fiestas,
religious processions, assistance with the upkeep of the parish church and the
priest’s administration of Christian sacraments. This achievement, however,
also created a complication in the coherence and imaginary matrix of spiritual
conquest, because it gave way to other forms of native participation in the
imagination and construction of the mission settlements.
AN EXTENDED K-MEANS CLUSTER HEAD SELECTION ALGORITHM FOR EFFICIENT ENERGY CONSUMPTION IN WIRELESS SENSOR NETWORKS
Authors: Maina Mwangi Peter , Gichuki Ndia John , Muchiri Muketha Geoffrey
Published: June 2023

Effective use of sensor nodes’ batteries in wireless sensor networks is critical since the batteries are difficult to recharge or replace. This is closely connected to the networks’ lifespan since once the battery is used up, the node is no longer useful. The entire network will not function if 60 to 80% of the nodes in it have completely depleted their energy. In order to minimize energy usage and sustain the network for a long time, many cluster head selection algorithms have been developed. However, the existing cluster head selection algorithms such as K-Means, particle swarm selection optimization (PSO), Density-Based Spatial Clustering of Applications with Noise (DBSCAN) and Fuzzy C-Means (FCM) cluster head election algorithm have not fully reduced the issue of energy usage in WSN. The objective of this paper was to develop an extended K Mean Cluster Head selection(CHS) algorithm that uses remaining energy, distance between node and base station, distance between nodes and neighbour nodes, node density, node degree Maximum Cluster size, received signal strength indicator (RSSI) and Signal to Noise Ratio. The algorithm developed was used to enhance the lifespan of WSNs. The performance of the simulated variants of LEACH routing protocols is measured and evaluated using the quantitative research methodology. Utilizing residual node energy, packet delivery ratio, throughput, network longevity, average energy usage, and the number of live and dead node, the suggested approach is contrasted to previous approaches. From the study we observed that the proposed approach outperforms existing actual LEACH, Mod-LEACH and TSILEACH approaches.

Pesticide refers to all chemical compounds which are mainly used in agriculture to control pests and weeds. In many developing countries, the increasing use of pesticides is due to agricultural activities for intensification purposes. The potential consequences for the environment, health and biodiversity are difficult to anticipate, as the presence of pesticides is difficult and rarely monitored. This is the case in the upper Mekong delta in Cambodia where many irrigation systems are being developed. The aim of the study is to provide a preliminary assessment of the situation by looking for the presence of pesticides in the water within a representative irrigation system. Water samples were collected in canals, river, irrigated rice field and groundwater in both dry and wet seasons. Solid-phase extraction (SPE) and gas chromatography-mass spectrometry (GC-MS) methods were used to purify and analyze the samples. Among 37 pesticides used by farmers and detectable, 6 were found in water. Paclobutrazol and propiconazole are moderately hazardous, hexaconazole is slightly hazardous, fluquinconazole presents acute toxicity and azoxystrobin is unlikely to present acute hazard. Hexaconazole and paclobutrazol are classified as highly persistent in water, while others are slightly to moderately persistent. Pesticides were found mostly in groundwater but they were found in the canals and rice field only in dry season. This means that pesticides may accumulate in the aquifer while the flooding has a flushing effect on pesticides. Further analyses should be extended to a bigger scale and be continued monitoring.

Published: June 2023

The teaching of Physics has faced a number of problems of epistemological and didactic order. Discipline is seen by many as not only difficult to be learned as to be taught. This study highlights the contributions of virtual laboratories, as element mediator/facilitatorof the teaching-learning process able to promote the building of meaningful learningsince many phenomena can not be played in the classroom or in a real lab. As a possibility that should also be considered from the perspective of teacher training, especially in undergraduate programs in physics, as a means to overcome the fragmented training with the overlay of theoretical knowledge about the knowledge of the practice. The research brings inclusion of the perspective of the virtual laboratory as an important resource for the learning process. This study was based on theoretical contributions from: Ausubel, Lapa, Medeiros, Paulo Freire, PCNEM (2000), Perrenoud (1993), Prensky, Moreira (1997), Silva (2005), Vygotsky (1991),and Wolfgram (1994).

A pesquisa exploratória coletou dados de 120 alunos, com idades entre 14 e 18 anos, em duas escolas de nível médio da rede estadual dos municípios de José de Freitas e Campo Maior, ambos localizados na região norte do estado do Piauí. Os resultados apresentados neste trabalho foram coletados através de questionário com questões objetivas relacionadas às principaisdificuldades enfrentadas pelos alunos na disciplina de física. O principal objetivo foi analisar a concepção dos alunos sobre o processo de ensino-aprendizagem e discutir os motivos que os levaram a considerar a disciplina de física difícil. A pesquisa revela que 75,83% dos alunos têm algum tipo de dificuldade em física e que as duas maiores dificuldades são: solucionar os cálculos e compreender a teoria. Este trabalho mostrou que ainda é grande o percentual de alunos que têm dificuldades na disciplina, pois grande parte possui notas abaixo da média, apesar do sistema educacional ter melhorado. Os alunos apontam que para melhorar o ensino-aprendizagem deve-se investir em laboratório didático, formação de professores, conteúdos atuais, metodologias e recursos didáticos

ENHANCED TOTAL PHENOLIC CONTENT EXTRACTION FROM CUCUMIS MELO L. (KULTIK) KERNEL BY DEEP EUTECTIC SOLVENT (DES)
Authors: AYDIN Çağlar Mert
Published: June 2023

Kernel of Cucumis melo L is a by-product produced from the water-melon production process. The phenolic compounds could be considered as a potential bioactive source for industrial applications. Therefore, the extraction of these compounds as much as possible will decrease valuable waste and could lead to produce value-added products. In the first part of this study, comparation of the effect of DESs and conventional solvent on total phenolic content (TPC) was performed. Some DESs had significantly better extraction yield than conventional solvent. Therefore, optimization of extraction conditions was performed by single factor experiment.

Optimized parameters are molar ratio, type of HBA (hydrogen bond acceptor), addition of water content, extraction time and extraction temperature. From the results obtained, all these parameters were found to have an impact on TPC extraction yield. Also, it is noteworthy that the extraction yield using some selected parameters was on decrease after a certain extent. The best extraction parameter for Cucumis melo L. was found to be choline chloride as HBA, 1:4 molar ratio, %30 water addition, 500 extraction temperature and 30 min extraction time. This result confirms that kernel of Cucumis melo L. is a valuable ingredient due to its bioactive content, DESs could be a good alternative to conventional solvents and the industrial applications of DESs could be possible.
Lifelong Learning Motivation Scale (LLMS):Validity and Reliability Study
Authors: USTA Ertuğrul
Published: June 2023

The aim of this study is to develop a scale for measuring lifelong learning skills in both young and adult individuals. A total of 275 participants, ranging in age from 14 to 55, took part in the study. The first step in creating the scale item pool involved conducting a thorough literature review. Existing scales related to the subject were examined, and based on these findings, an initial 18-item form was developed. The scale item pool was then presented to two experts who are academicians in the field of lifelong learning, as well as a scale development expert. Their input was taken into account, resulting in corrections and refinements to the scale trial form. Following this, the revised scale trial form was administered to the participants. To assess the construct validity of the scale, an exploratory factor analysis was conducted. This analysis revealed that 7 items needed to be removed from the scale. Ultimately, the scale was found to consist of five factors. The first factor included 5 items, while the remaining factors consisted of 3 items each. Next, a confirmatory factor analysis was performed to determine the relationships between the factors, the relationships between the variables and the factors, the relationships between the factors themselves, and the degree to which the factors explained the model. The Cronbach's alpha reliability coefficient for the scale was found to be .646. Based on these results, the Lifelong Learning Motivation Scale (LLMSS) was developed to address the existing gap in the literature and provide a useful tool for future research and applications related to lifelong learning.
