The development of functional literacy of students from specialized schools is currently relevant. The aim of the study is to analyze the process of development of functional literacy and its component of natural science literacy in chemistry lessons in the conditions of implementation of shortened curricula in specialized general education schools of the Republic of Kazakhstan. The scientific achievements of foreign and Kazakh scientists on the identified problems were studied, on the basis of which conclusions were made about the need to use the capabilities of the activity methodology. This necessity is a consequence of the observed transformation of the education system in the country. The content of normative documents regulating the system of general secondary education is also analyzed, according to which the chemistry teacher has the right to independently determine the number of hours allocated to study, which gives the teacher of a specialized school the opportunity to independently decide on the choice of ways to develop special competencies of students within their subject. The requirements to the tasks for assessing the level of science literacy were studied, and as a result, the necessity of defining the competence-skill as a parameter of competence was revealed. A table of matching skills (competencies) corresponding to tasks with a description of their characteristics was derived. It is concluded that it is possible to develop tasks that would ensure the development of competencies that include: scientific explanation of phenomena, understanding of the features of scientific research.

The article discusses the main physiological features of the formation of productivity elements of three species of miscanthus (Giganteus, Sinensis and Sacchariflorus) in drought conditions. The aim of the study is the comprehensive characterization of the responses of three miscanthus species under conditions of water deficit in order to identify potential mechanisms of drought resistance of this crop and assess the possibility of its cultivation in a more arid climate. The objectives of the study included assessing the level of biomass accumulation by miscanthus plants under normal and drought conditions, determining growth indicators and indicators of functional activity, as well as evaluating indicators of the aquatic regime of miscanthus plants. The results obtained indicate the presence of a wide species-specificity of the responses of miscanthus plants to water deficiency. In the case of prolonged drought, the relative growth rate of all miscanthus species decreases. In Miscanthus sacchariflorus drought leads to the decrease in photosynthesis productivity, but the efficiency of water consumption in these plants remained at the plant level in conditions of normal water supply. Miscanthus giganteus and especially miscanthus sinansis have found a wider range of reactions to drought, which includes not only maintaining photosynthetic productivity, but also optimizing it, as well as increasing the efficiency of water utilization. In the miscanthus of the studied species, two strategies for adaptation to conditions of draught were confirmed - the preservation and maintenance of vital processes in conditions of water deficit, along with the presence of mechanisms that optimize the efficiency of water consumption.

The article presents the characteristics of linear evaluation of exterior of the first calving heifers of different lineage in the conditions of dairy complex of Beck+ LLP located in the Fyodorov district of the Kostanay region. Three experimental groups of cows were formed based on the different lineage of their first calving: Vis Back Ideal, Reflection Sovereign, and Osborndale Ivanhoe. The assessment of first-calving cows' exterior traits was conducted using 24 indicators and 9-point scale from day 30 to day 150 of lactation. Throughout the study, cows from the Vis Back Ideal and Reflection Sovereign lines demonstrated their superiority in overall body conformation, dairy type, and limb structure compared to their herd mates from the Osborndale Ivanhoe line. Across most of the evaluated traits such as hip height, rear width, udder depth, udder attachment, and hind leg posture, first-calving cows from the Vis Back Ideal line exhibited an advantage over those from the Reflection Sovereign and Osborndale Ivanhoe lines. A comprehensive evaluation of exterior traits was conducted, revealing that first-calving cows from the Vis Back Ideal and Reflection Sovereign lines are classified as "good," while their herd mates from the Osborndale Ivanhoe line are classified as "satisfactory." These finding confirm that servicing bulls significantly influence the expression of linear exterior traits in offspring.

Authors: Şahin Mahmut , Kara Haki
Published: April 2024

This study was conducted to compare Mebendazole in terms of its apoptosis–inducing and tubulin–inhibitory effects when combined with vincristine and paclitaxel, both of which are used in cancer treatment. Lung fibroblast cells (MRC–5) and small cell lung carcinoma (NCI–H209) cell lines were used in the study. Concentrations of Mebendazole, vincristine, and paclitaxel at 0.5 µM, 1 µM, 1.5 µM, and 2 µM were separately applied to these cell lines, as well as in combinations. After the cells were kept in the culture medium for 24 hours following drug administration, cell proliferation, apoptotic DNA levels, caspase 3, 8, and 9 levels, and in vitro wound healing experiments were performed. It was determined that Mebendazole suppressed cell proliferation and cell healing, increased caspase–3, caspase–8, caspase–9 levels and apoptotic DNA formation in NCI–H209 cancer lung cells. Compared to the groups given Mebendazole and vincristine alone, it was observed that cell proliferation was more suppressed and, the level of apoptosis increased in cancerous cells in the groups given the combination of the two drugs. According to the findings obtained from the present study, it was believe that Mebendazole may possess therapeutic activity against cancerous lung cells (NCI–H209) due to its apoptosis–inducing and cell proliferation–suppressive effects.

Masalah utama pada penelitian ini adalah rendahnya hasil belajar siswa kelas VIIIA di MTs Alkhairat Luwuk pada materi kubus. Hal tersebut disebabkan oleh kurangnya perhatian pada proses pembelajaran, malu bertanya pada guru, serta kurangnya latihan dalam menyelesaikan soal sehingga siswa kesulitan dalam menyelesaikan soal yang berkaitan dengan materi segitiga. Maka untuk mengatasinya, dilakukanlah penelitian tindakan kelas. Peningkatan hasil belajar siswa dari 58,69% pada siklus I menjadi 89,78% pada siklus II. Peningkatan hasil observasi siswa dari 66,67% pada sikus I, menjadi 96,36% pada siklus II. Peningkatan hasil observasi guru dari 71,67% pada sikus I menjadi 98,81% pada siklus II. Indikator keberhasilan disetiap siklus mengacu pada keberhasilan proses pembelajaran mencapai 85%, keberhasilan observasi guru maupun respon siswa mencapai lebih dari atau sama dengan 75%. Hasil penelitian menunjukkan bahwa indikator keberhasilan pada pelaksanaan siklus 1 belum tercapai. Melalui refleksi dilakukan peninjauan kembali penerapan model pembelajaran Improve kemudian melanjutkan tindakan ke siklus 2. Dimana indikator keberhasilan dapat tercapai pada siklus 2. Hal ini menunjukan bahwa penerapan model pembelajaran Improve pada materi bangun ruang dapat meningkatkan hasil belajar matematika siswa kelas VIIIA di MTs Alkhairat Luwuk.

Good-quality chocolate can be produced only from good-quality cocoa beans. The cocoa bean quality can be improved using indigenous Lactiplantibacillus plantarum HL-15 as a starter culture in fermentation. The functionality of chocolate can be enhanced by the addition of probiotic L. plantarum Dad-13. This research aimed to evaluate the physicochemical, microbiological, and sensory characteristics of the probiotic chocolate bar Dad 13 made from fermented cocoa beans L. plantarum HL-15 during storage at different temperatures. The research was conducted in three stages. The first stage was the cocoa bean fermentation with and without L. plantarum HL-15, the second stage was probiotic chocolate bar Dad-13 production, and the third stage was the storage of probiotic chocolate bar Dad-13 at temperatures of 4 and 26°C. This study found that adding L. plantarum HL-15 to the fermentation could produce good-quality cocoa beans, prevent the growth of fungi presented by the pH and Aw of cocoa beans, and form a probiotic chocolate bar during storage. Storage at 4°C maintained the viability of L. plantarum Dad-13 and minimized fat breakdown. The organoleptic attributes of the probiotic chocolate bar Dad-13 during storage at 4 and 26°C were not significantly different (p > 0.05).

Bivalve molluscs are invertebrate organisms of economic relevance in several regions of the world. Due to their commercial importance, this study aimed to monitor the hygiene and sanitary quality of Perna Perna mussels (Linnaeus, 1758), from commercial farming and extractivism in Jurujuba, Boa Viagem and Centro, Niterói, Rio de Janeiro, Brazil. Collections were carried out once a month, from January to December 2022, in 1,080 animals, for bacteriological evaluation by the MPN of coliforms at 35°C, 45°C and Escherichia coli, according to the “Fluorocult LMX” Broth method. The results obtained in fresh mussel samples of coliforms at 45°C (E. coli) ranged from < 3.0 to 4.0 x 102 MPN/100 g, and animals from Jurujuba had the highest geometric mean of contamination and a higher 90th percentile level. A percentage of 22.2% of samples with satisfactory quality for consumption was obtained, according to the National Safe Bivalve Molluscs Program (MoluBiS). It is concluded that it is necessary to implement the aforementioned Program in the state of Rio de Janeiro to monitor sanitary conditions, so that the minimum requirements to guarantee the safety and quality of bivalve molluscs for human consumption are provided.

Esta pesquisa tem como objetivo investigar as dificuldades encontradas pelos professores de Biologia de vinte e seis Escolas Públicas, localizadas nos seis distritos da cidade de Fortaleza, Ceará. Os dados foram obtidos por meio de entrevista, usando questionário qualitativo e quantitativo. As dificuldades enfrentadas no ensino estão entre realizar a aula de campo, o desinteresse do aluno e a terminologia. Porém, os termos específicos não necessariamente estão relacionados com o desinteresse pela área, já que Zoologia mesmo sendo considerada com termos mais difíceis ainda é a disciplina de maior interesse. A grande maioria (42,31%) apresenta interesse mediano pela Biologia Vegetal mesmo percebendo que é um conteúdo de grande importância. Quanto ao ensino, consideram menos importante para os alunos (29,17%) por motivos como “não serem muito cobrados em avaliações e serem menos interessantes, podendo assim ser refletido na aprendizagem dos alunos”. Dentre os assuntos que mais despertam interesse dos professores é Angiospermas, isso pode ser explicado pelo livro didático que é organizado de forma a privilegiar esse assunto. Em contrapartida, a morfologia vegetal é considerada mais difícil de lecionar, por ser muito aprofundada e os alunos tendem a ter dificuldades em aprender os conceitos necessários. Apesar das diversas dificuldades na educação básica como falta de infraestrutura da instituição de ensino e desinteresse dos alunos, a determinação e motivação dos professores na ação pedagógica é significativa para o processo educacional.
