O objetivo deste trabalho foi validar um método quantitativo para determinação de L-fenilalanina (Fen) em farinha de trigo por espectrofotometria derivada segunda. A amostra de farinha de trigo, na quantidade de 0,525g, foi submetida à hidrólise ácida com HCl a 5,7 mol/L, a 110 °C, por 24 h. O material hidrolisado foi reconstituído para 50 mL com tampão fosfato de sódio a 0,1 mol/L, pH 7,0. As soluções preparadas a partir dessa amostra foram submetidas às leituras de absorvância, entre 230 nm e 280 nm, em espectrofotômetro UV/VIS. Os espectros de derivada segunda foram traçados e os valores das áreas dos picos negativos foram utilizados para estimar os teores de Fen. A linearidade do método foi demonstrada na faixa de 0,010 mg/mL a 0,035 mg/mL (correspondente a teores de 251 mg/100g a 877 mg/100g de Fen em farinha de trigo). Efeitos de matriz foram observados. A determinação de Fen não sofreu interferência de compostos como L-tirosinae L-triptofano. As porcentagens de recuperação variaram de 81 % a 118 % e os desvios padrão relativos de repetitividade e reprodutibilidade parcial foram respectivamente 11 % e 15 %, para amostras contendo 354 mg/100g, demonstrando adequada recuperação e precisão do método. Os limites de detecção e quantificação foram, respectivamente, 63 mg/100ge 175 mg/100g. Os parâmetros de desempenho estudados indicaram adequação do método para o monitoramento e controle de teores de Fen em farinha de trigo.

Neste estudo foi avaliada a estabilidade microbiológica da polpa de cajá conservada por métodos combinados e armazenada em temperatura ambiente por um período de 90 dias. A análise foi realizada por meio de determinações do número mais provável (NMP) de coliformes termotolerantes, contagem de bolores e leveduras e pesquisa de Salmonella spp. O delineamento foi inteiramente randomizado em esquema fatorial de 4 x 2 x 4 (tratamentos x processamento x tempo) com cinco repetições. Os processamentos de polpa sem pasteurização e polpa pasteurizada (90-93ºC/15min) foram combinados aos tratamentos: controle, metabissulfito de sódio (200 ppm), benzoato de sódio (500 ppm) e metabissulfito (200 ppm) + benzoato (500 ppm). O produto mostrou estar de acordo com a regulamentação técnica da legislação brasileira, que estabelece os padrões de identidade e qualidade para polpa de cajá, quanto aos limites microbiológicos. Com exceção das polpas sem pasteurizar, controle e combinada com benzoato de sódio, os demais tratamentos combinados promoveram o controle de bolores e leveduras da polpa durante o período avaliado. Entre estes, a formulação da polpa pasteurizada combinada com metabissulfito de sódio, apresentou maior eficácia no controle da carga fúngica com manutenção do produto apto ao consumo aos 90 dias.

Em janeiro de 2010, foi realizada uma vistoria sanitária pelos técnicos da ANVISA, em um navio durante a escala no porto de Santos/SP, pela ocorrência de distúrbios gastrointestinais nos passageiros e tripulantes, após a escala em Búzios, RJ. Foram coletadas amostras dos alimentos preparados: ensopados de peixe, de carne, de frango e de porco; salada de batatas com maionese, saladas grega e mista com macarrão; molho de maionese com ketchup e amostras de água potável de cinco pontos. As amostras foram analisadas segundo as metodologias descritas no “Compendium of Methods for the Microbiological Examination of Foods”, da American Public Health Association (2001) e “Standard Methods” (2005). Foi isolado Bacillus cereus no ensopado de peixe e coliformes a 35ºC no reservatório de água potável do navio. Coliformes totais e termotolerantes, Staphylococcus aureus coagulase positiva, clostrídios sulfito redutores, Bacillus cereus e Salmonella spp não foram isolados dos demais alimentos, tampouco Escherichia coli das amostras de água. A ocorrência de Bacillus cereus no ensopado de peixe com valores acima do limite de tolerância estabelecido pela Resolução RDC nº 12/2001, da ANVISA/MS, pode ser a causa de surtos de toxinfecção alimentar nos passageiros e tripulantes de navios de cruzeiros.

Avaliou-se a influência do líquido da casca da castanha de caju sobre as características físicoquímicas e sensoriais das castanhas fritas e salgadas. Foram determinados a composição centesimal, o valor calórico, a acidez e o pH das castanhas. A análise descritiva quantitativa estabeleceu atributos capazes de descrever com fidedignidade as características sensoriais: cor, uniformidade da cor, aroma torrado, aroma doce, aroma de ranço, aroma velho, crocância, sabor torrado, sabor doce, sabor de ranço, sabor velho, sabor salgado, sabor amargo e qualidade global. As amostras sem manchas do líquido da casca apresentaram maiores percentuais de umidade, cinzas e proteínas, o conteúdo lipídico foi superior naquelas com manchas. As amostras de castanhas manchadas apresentaram médias superiores para sabor amargo e crocância, os demais atributos não apresentaram diferenças significativas. As características que mais influenciaram positivamente na qualidade global foram: cor, crocância, sabor torrado, aroma torrado, sabor doce e sabor salgado. Todas as amostras apresentaram boa aceitação sensorial. O processo de fritura seguido da salga resulta em boa aceitabilidade; mesmo após esse processo, a presença do líquido da casca reduz a aceitação, por ocasionar sabor amargo mais intenso. A fritura e a salga minimizam, mas não mascaram o sabor residual do líquido da casca.

Segundo a norma ISO 17.025, os instrumentos usados em experimento devem ser calibrados. No caso de micropipetas não há limite máximo de erro definido, sendo difícil estipular até que ponto uma micropipeta pode continuar a ser usada. O objetivo do trabalho foi o de determinar a porcentagem de erro no volume da micropipeta que não interfira nos resultados das diferentes etapas do ensaio toxicológico Lisado de Amebócitos de Limulus (LAL). Os percentuais de erro foram obtidos do levantamento de 44 certificados de micropipetas. Foram utilizados uma pipeta monocanal calibrada, de volume variável e kit LAL Cromogênio QCL-1000 (Lonza). A curva de endotoxina foi construída com as concentrações de 0,1; 0,25; 0,5 e 1 UE/mL. Os percentuais de erro de ±2%, ±4% e ±10% foram comparados com a concentração de referência (0,5 UE/mL), e analisados pelo Student t-test (p<0,05). A análise estatística mostrou que, para a endotoxina padrão e para o substrato do LAL, erro acima de 2% interfere nos resultados, cuja correção deve ser feita pelo ajuste do volume na pipeta. Nenhum erro testado causou interferência estatisticamente significativa na reação da cor do substrato. Micropipetas com erro superior a ± 2% devem ser corrigidas.

Published: November 2023

This research is a qualitative research with a case study approach. The reason for using case studies is that this research examines existing cases so that researchers only study existing cases. This research will be conducted at SDN 106161 Percut Sei Tuan. The time of this research was carried out in March-April 2022. The total informants needed were 2 fifth grade teachers and 6 students. Determination of informants in this study was done by purposive sampling technique. After describing the results and discussion, the conclusions in this study are determined:1) For the value of patriotism, according to the researcher, the students of SDN 106161 Percut Sei Tuan have a good attitude of nationalism but still don't know much about the values of nationalism that must be fostered. Then students also have social care for fellow friends, family and teachers as well as for surrounding creatures such as animals that pass around the school and the plants that grow around the school are cared for properly. 2) The problem related to social care and love for the homeland lies in the lack of enthusiasm for students showing these 2 characters in learning and the importance of these two attitudes, considering that at present the problem of love for the homeland is very minimal for children because of global influences, technology and the entry of foreign culture into Indonesia so that it affects children. 3) The process of implementing experiential narratives where learning is carried out with the concept of telling the experience of role models in this country related to the Proclamation and Presidents 1 and 2 in Indonesia has been carried out very well

A Review of Machine Translation Quality Assessment Methods
Authors: Wang Wenbo
Published: November 2023

Machine translation quality assessment plays a crucial role in enhancing the performance of machine translation systems. This review aims to survey and outline the current major methods used for assessing machine translation quality, which can be broadly categorized into manual and automatic assessment methods. Upon analyzing the existing literature, it becomes evident that while manual evaluation methods yield high-quality results, they are time-consuming and labor-intensive. On the other hand, automatic evaluation methods are cost-effective and rapid, but their evaluation results do not match the expertise of human evaluators. The objective of this paper is to furnish researchers with a comprehensive overview of machine translation quality assessment methods, enabling them to select appropriate approaches based on their specific experimental requirements. Additionally, we aspire to offer valuable insights and novel perspectives for further advancements in the field of machine translation quality assessment methods.
Research on Weibo New Word Recognition based on Weibo Data and Statistical Information
Authors: Xu Yuanfang
Published: November 2023

One of the key challenges in the field of Chinese information processing is the recognition of Weibo new words, which has a profound impact on machine translation and text classification. As Weibo has become the most used social platform for internet users, mining new vocabulary from Weibo data not only helps to deeply understand the data itself, but also provides personalized recommendation services for users. Although a large amount of research has focused on the recognition of Weibo new words, specialized research in this field is still scarce. In this article, we propose a Weibo new word recognition strategy that combines Weibo content features and statistical information. Firstly, extract repetitive vocabulary from Weibo topic names, and then use various methods such as absolute frequency, relative frequency, mutual information, and information entropy to filter for incorrect vocabulary. The experimental results show that by setting appropriate thresholds, incorrect vocabulary can be effectively filtered out, thereby improving recognition performance.

Increasing access to education through the re-entry policy for girls after school pregnancy could be seen in terms of bringing about social justice and equity in education, especially in developing countries, and enabling them to realise its benefits. This strong international and philosophical commitment is different from the traditional view of education as preparation for life roles. Therefore, implementing it in the African context might be expected to raise several problems, possibly resulting in a lack of commitment on the ground. The purpose of this study was to assess the views of stakeholders on the re-entry programme of teenage mothers into secondary schools in Unguja Urban-West district, Tanzania. The study used a mixed method approach and convergent mixed methods design. The study used a sample size of 160 participants, including teachers and parents. The findings revealed that stakeholders were sceptical of the success of this policy. Teenage mothers do not have enough time to complete their homework and to study at home because their relatives who take care of the babies want to be free of child chores the moment they are back at home. The babies also want attention from their mothers when they return from school. For effective implementation of school re-entry programme among teenage mother, schools should create an enabling learning environment that accommodates both the needs of teenage mothers and their children.
Therapeutic aspects of dietary fibre and glycemic index: a brief review
Authors: AHSAN Haseeb
Published: November 2023

Simple sugars, complex polysaccharides, and dietary fibres are all examples of dietary carbohydrates. A healthy diet should consist of more complex and less added carbohydrates. Dietary fibre is a non-digestible carbohydrate that is not digested and absorbed by the body but is required for satiety and bowel motility. Dietary fibre contains cellulose, hemicellulose, pectins, gums, mucilages, and lignin, which are resistant to enzymatic digestion. Various components of dietary fibre include arabinoxylan, inulin, β-glucan, pectin, bran, and resistant starches. Dietary fibre is a carbohydrate that resists digestion and absorption in the large intestine and may or may not be fermented by bacteria. Short chain fatty acids (SCFAs) are produced in the gut by the breakdown of fibre by intestinal microorganisms and offer energy calories (2 kcal/g). Dietary guidelines recommend increasing the dietary fibre intake since a high fibre intake provides health benefits and prevents dietary and life-style diseases. The aim of the present review article is to understand and suggest better dietary carbohydrates containing high fibre with low glycemic index for the prevention of diabetes, obesity and lifestyle diseases. The different types of carbohydrates in the diet need further recommendation to elucidate its function in health and diseases.
El consumo en la producción del espacio: una propuesta categorial a partir de la relación dialéctica producción-consumo del espacio urbano

Desde el mismo momento en que el filósofo francés Henry Lefebvre publicó su obra cumbre “La Producción del Espacio'' en 1974, el estudio sobre el espacio se tornó un campo de reflexión clave alrededor del papel que este podría cumplir en el capitalismo. No obstante, y a pesar de los avances en dicha materia, el consumo del espacio carece de una equivalencia categorial (de método) frente a la producción del espacio, lo que significa que el fundamento dialéctico de la producción-consumo se ha reducido a la relación valor de uso-valor de cambio, dejando en un segundo plano el par dialéctico trabajo vivo-trabajo muerto. Así, la propuesta presentada de manera teórico-reflexiva, se centra, en primer lugar, en la construcción de un consumo abordado como término universal y no solo singular en la relación producción-consumo, lo que implica la ampliación de escalas, temporalidades y espacios (lo que aquí se denominó espacios-otros), y en segundo lugar, enfatiza la relación necesidad-satisfactor pensada desde el plano cotidiano, esto es, sobre el horizonte de representación (inmediato y directo) y ocultamiento (de procesos históricos y universales) de los fenómenos de reproducción social propios de la sociedad moderna.

The phenomenon that happens in communication, especially in terms of speech acts often becomes an issue in society. The function of a language or utterance that does not only contain literal meaning but has a certain intended meaning often causes misunderstanding in communication. Since the development of technology, speech acts also can be found in a movie. Since, in the movie, the producer sometimes raises a story of a certain social life, Di Timur Matahari's movie was chosen to be the object of the study. This movie raised the culture of north Indonesia (Papua). A descriptive qualitative method was applied in this study. From collected data, some types of illocutionary acts were found. Those were expressive, assertive, and directive. The most dominant type of illocutionary acts found in the utterance was directives. The result of this study is essential because it shows what type of illocutionary act that was mostly used in the movie.

Fire and herbivory – key drivers of temperate open ecosystems : Effects of consumer control on woody and herbaceous plant communities in temperate wood-pasture
Authors: Amsten Karin
Published: November 2023

The decline of open and semi-open habitats is an important reason behind the ongoing worldwide loss of biodiversity. Understanding the drivers of habitat openness is an important key for preventing the continued loss of these ancient ecosystems. In other continents, fire and herbivory are well-studied and identified as important processes in preventing open habitats from turning into closed forests. The aim of this thesis is to apply the established concept of consumer control in a new context: the northern areas of temperate Europe. In a large field experiment in a Swedish wood-pasture, we first studied how two consumers, prescribed grass fire and grazing by cattle, alone or in combination, affected the survival and growth of planted tree saplings (I). The tree species demonstrated different strategies to resist fire or herbivory. Either they survived by re-sprouting or they quickly grew out of reach of the consumers. In addition, we studied the effect of the two consumers on the establishment and reproduction of sowed open habitat forbs (II). Herbivory improved the conditions for the establishment of forbs, but fire promoted the production of inflorescences. A release of grazing pressure increased the number of remaining flowers at the end of the growing season, confirming the importance of variation in herbivory intensity over time for the persistence of forbs. In a third study, we studied the interaction between fire and cattle grazing (III). We followed the foraging behaviour of cattle with camera traps and found that when a larger proportion of an area was burned, the cattle preferred to graze in the newly burned areas. This led to a reduction in fuel, altering the future fire pattern. In a final study, we evaluated the long-term effects of fire and herbivory by comparing the biomass of woody and herbaceous vegetation (IV). Without fire and herbivory, trees out-shaded grasses and forbs, leading to conversion from an open grassy ecosystem to a tree-dominated forest. In conclusion, herbivores and potentially also fire can be important drivers of openness, also in temperate Northern Europe, but further research is needed to understand the effect of different fire and grazing regimes.
