A Astronomia era usada por muitos povos para buscar respostas para alguns fenômenos naturais, contribuindo para a organização cronológica da sociedade, períodos de plantações, desenvolvimento da navegação, entre outros. Contudo, a Astronomia é pouco abordada nas escolas do Brasil, pois a falta de estrutura adequada, a não obrigatoriedade no currículo das escolas, além de ser uma ciência que demanda o uso de métodos experimentais em sua aplicação, e isso contribui para que conceitos nessa área não sejam desenvolvidos. Este trabalho é resultante de uma pesquisa que objetivou mostrar uma didática com utilização de materiais alternativos e acessíveis para o estudo de tópicos de astronomia, que promovam o seu interesse, importância e emprego em sala de aula. Para realização do projeto foram usadas aulas desenvolvidas na Escola Militar Tiradentes “Cabo José Martins de Moura”, com estudantes do 1º ano do Ensino Médio. As aulas foram organizadas em forma de oficinas e realizadas no contraturno, sendo divididas em três etapas: aulas teóricas ou de apoio, construção dos experimentos e socialização dos experimentos, abordando conceitos de Astronomia. Como instrumento para a coleta de dados foi aplicado um questionário, contendo seis questões, para avaliar a importância das aplicações práticas e dos experimentos para a compreensão dos conceitos de Astronomia. Os resultados apontaram que os estudantes envolvidos no projeto apresentaram boa aceitação das atividades propostas, facilitando a compreensão de alguns tópicos da Astronomia, tais como: Leis de Kepler, Fases da Lua e Eclipses, bem como sua importância para o desenvolvimento da sociedade.

Identification of key performance dimensions of academic professionals: A qualitative exploration
Authors: Imran Sheikh
Published: June 2024

This study seeks to explore the dimensions of performance of academic professionals in various universities in Bangladesh. This qualitative study used 21 in-depth, semi-structured interviews to collect data from 10 public universities across four administrative regions of Bangladesh. The data was analyzed thematically using the interpretive phenomenological approach in NVivo 12 Pro software. This study has identified four crucial performance characteristics of academic professionals in public institutions in Bangladesh. These dimensions include teaching, research and publication, administrative tasks, and managing external funds. The results also indicated that academic professionals must participate in this activity throughout their careers. A range of respondents' perspectives were utilized to characterize the performance aspects of academic professionals. During the process of selecting the university category, there was some overlap. For instance, this study does not include private universities, medical universities, other specialized universities, and off-campus universities in Bangladesh. There is a better possibility of getting better outcomes if all kinds of universities are included in this study. By outlining the shortcomings of the present study, the article also serves as a rallying cry for additional research. The findings of the study will improve the understanding of the academic professional about the key performance dimensions. The results also offer a useful framework for relevant authorities, HR departments, university administrations, and lawmakers by describing the most important aspects of academic professionals' performance that they must exhibit at different career points. The study sheds light on the possible societal contributions of performance and its various sub-dimensions. This research constructs a comprehensive model of the links between HRM practices, university authority orientation, and academic professionals' productivity based on theoretical assumptions and empirical evidence. This study's results have practical consequences because they examine critical components of academic professionals' performance that may influence their employment.

Authors: Lawrence Luhanga , George C. Angelopulo
Published: June 2024

This research investigates the dual impact of second screening on television viewing in Blantyre, Malawi, exploring the challenges it poses to traditional viewing practices and the opportunities it presents for broadcasters. Based on the Distraction-Conflict and Uses and Gratification theories, the study examines how second screening, the simultaneous use of secondary devices during television watching, affects viewer attention and engagement. Utilising qualitative methodologies, including focus groups and in-depth interviews, the research gathered insights from a diverse demographic in Blantyre. The analysis uncovered that second screening often leads to fragmented attention and reduced engagement with television content, posing significant challenges for content creators and broadcasters. However, the study also highlights potential opportunities for leveraging second screening to enhance viewer engagement, particularly through interactive content and social media integration. These opportunities suggest innovative strategies for broadcasters to reclaim viewer attention and foster a more participatory viewing experience. The findings of this study offer valuable implications for media producers, suggesting that embracing the complexities of second screening can lead to more engaging and immersive content strategies. Furthermore, this research contributes
to the understanding of media consumption dynamics in Malawi, providing a foundation for future studies in similar contexts where digital and traditional media intersect.
Megalithic Culture Research in Banyuwangi, East Java Province, Indonesia | Penelitian Budaya Megalitik di Banyuwangi, Jawa Timur, Indonesia
Authors: Taniardi Putri Novita
Published: June 2024

Previous research on the megalithic cultures of East Java, Indonesia was carried out in the regions of Situbondo, Bondowoso, Jember, and Probolinggo. The results demonstrated that there is a diversity of megalithic monuments and cultures in the area, both in terms of form and chronology. The latest project undertaken by the Megalithic Culture Research Team in Banyuwangi focuses on the megalithic monuments in Banyuwangi, the easternmost region of East Java. This research was conducted using surveys and excavations. The project has demonstrated that Banyuwangi possesses dolmens, a type of megalithic monument uncovered by excavation. Pottery fragments and beads were also recovered from the megalithic sites. Dating of pottery retrieved from the same contexts as the dolmens suggest that the megalithic culture of Banyuwangi originated in the 3rd to 6th centuries CE, or in the protohistoric period. This date is the oldest when compared to othermegalithic cultures in East Java. Thus, the results of this study contribute important new archaeological data to the diversity of megalithic cultures in Indonesia. Penelitian sebelumnya tentang budaya megalitik Jawa Timur, Indonesia dilakukan di daerah Situbondo, Bondowoso, Jember, dan Probolinggo. Hasilnya menunjukkan bahwa terdapat keragaman monumen dan budaya megalitik di daerah tersebut, baik dari segi bentuk maupun kronologis. Proyek terbaru yang dikerjakan tim penelitian budaya megalitik di Banyuwangi berfokus pada monumen megalitik di Banyuwangi, wilayah paling timur Jawa Timur. Penelitian ini dilakukan dengan metode survei dan ekskavasi. Proyek tersebut telah menunjukkan bahwa Banyuwangi memiliki dolmen, sejenis monumen megalitik yang ditemukan melalui penggalian. Pecahan tembikar dan manik-manik juga ditemukan dari situs megalitik. Penanggalan tembikar yang diambil dari konteks yang sama dengan dolmen menunjukkan bahwa budaya megalitik Banyuwangi berasal dari abad ke-3 hingga ke-6 Masehi, atau pada periode protohistoric. Pertanggalan ini merupakan yang tertua jika dibandingkan dengan kebudayaan megalitik lainnya di Jawa Timur. Dengan demikian, hasil penelitian ini memberikan kontribusi data arkeologi baru yang penting bagi keragaman budaya megalitik di Indonesia.
Enquiring the two transcendent Buddha statues of Cham art belonging to the Vijaya state in the 11th to 13th centuries | Tìm hiểu hai pho tượng Phật Chàm bằng đá thuộc Tiểu quốc Vijaya thế kỷ 11-13
Authors:   University of Social Sciences and Humanities, Vietnam National University, Ho Chi Minh City, Nguyễn Thị Tú Anh
Published: June 2024

Although the stone sitting Buddha statue from the Thủ Thiện temple has been documented by French scholars since the early 20th century, the Buddha figure currently on display at the Đà Nẵng Museum of Cham Sculpture remains a mystery in Cham Buddhist art from the 11th to 13th centuries. In addition to the other stone Buddha statue in meditation position on display at the Museum of Fine Arts in Ho Chi Minh City, these masterpieces are a challenge for modern Cham Buddhist art historians. This paper will argue that the Thủ Thiện’s Buddha image is Amoghasiddhi based on his hand gesture in abhaya-mudrā (gesture of fearlessness); while the other one is Vairocana with his hand gesture in bodhyāgrī-mudrā (the fist of wisdom). These two transcendent Buddhas may lead to the assumption that esoteric Buddhism was once practiced in the Campā kingdom during the Vijaya art period in the 11th to 13th centuries. It may also indicate the cultural relationships between Campā and the other Buddhist states during the time of esoteric Buddhism spreading throughout the entire Maritime Asia. Pho tượng Phật ngồi bằng đá thuộc di tích Thủ Thiện, Bình Định, đã được các học giả Pháp tìm thấy vào đầu thế kỷ 20; sau đó, tuyệt phẩm này đã được chuyển về trưng bày tại Bảo tàng Điêu khắc Chăm Đà Nẵng, tuy nhiên pho tượng này vẫn ẩn chứa nhiều bí ẩn chưa được tìm hiểu cho đến nay. Ngoài ra, một tuyệt tác điêu khắc đá khác cũng thể hiện đức Phật ngồi trong tư thế thiền định, đang trưng bày tại Bảo tàng Mỹ thuật Thành phố Hồ Chí Minh cũng thuộc thời kỳ Vijaya vào thế kỷ 11-13. Cả hai pho tượng vẫn còn là một thử thách đối với các nhà nghiên cứu nghệ thuật Campā trong việc thẩm định nội hàm của chúng. Tiểu luận này đặt giả thiết bức tượng Thủ Thiện là hình ảnh của đức Phật Amoghasiddhi dựa trên tạo hình ấn quyết abhaya-mudrā (vô uý thí); đồng thời giả định rằng đức Phật của Bảo tàng Mỹ Thuật TPHCM là Vairocana dựa trên ấn quyết bodhyāgrī-mudrā (trí huệ ấn). Hai pho tượng Phật này đưa đến nhận định rằng Phật giáo Mật tông từng được thực hành phổ biến tại vương quốc Campā vào thời kỳ Vijaya thế kỷ 11-13. Nhận định đó đồng thời phác họa mối liên hệ Phật giáo giữa Campā và các quốc gia khác trong suốt thời kỳ Phật giáo Mật tông phát triển, dựa trên mạng lưới hải thương châu Á đương thời.

Published: June 2024

This paper presents an overview of the rock art sites in Perlis of West Malaysia, namely Gua Bintong, Gua Semadong, Bukit Jernih, and Bukit Tengku Lembu. In general, the Perlis rock art consists of black charcoal drawings with a wide variety of motifs such as anthropomorphs, zoomorphs, watercraft, geometric shapes, ray motifs, and abstract designs. This paper provides new insights into the rock art from Perlis and further explores their relationship with other rock art sites across West Malaysia. We propose that the rock art from these sites were possibly made between middle 19th to 20th century CE by the Negrito Orang Asli. Kertas kerja ini membentangkan tapak-tapak lukisan gua di Perlis, iaitu Gua Bintong, Gua Semadong, Bukit Jernih dan Bukit Tengku Lembu. Secara amnya, lukisan gua di Perlis terdiri daripada lukisan arang yang berbentuk seperti manusia, haiwan, kapal, geometrik, sinar, dan reka bentuk abstrak. Kertas kerja ini memberi perspektif baharu mengenai lukisan gua di Perlis dan seterusnya menerokai hubungannya dengan tapak-tapak lukisan gua lain di Semenanjung Malaysia. Kajian ini mencadangkan bahawa lukisan gua di Perlis dihasilkan antara pertengahan abad ke-19 dan ke-20 oleh Orang Asli Negrito.

Machine Learning for the recognition and analysis of prehistoric rock art and pottery is a promising area of research that could reveal new insights into cultural heritage and identity. Deep Learning (a form of Artificial Intelligence) can now be used to train powerful models to automatically recognise pottery and rock art images, overcoming resource constraints such as time, manpower, and lack of funding. This article provides a preliminary overview and proof of concept by providing Machine Learning approaches based on current advancements in Deep Learning to train a model to recognise images of pottery and prehistoric rock art. These methods can process large amounts of data quickly and accurately, revealing new patterns and relationships. Although ML can be a complex undertaking, new tools make it accessible to the archaeological practitioner who is not an AI expert. แมีชี่ชีี่นเลิ่ร์นนิงสีำาหรับัการจดจำาแล่ะวิเค้ราะห์ศิิล่ปัะหินยุค้ก่อนปัระวัติศิาสีตร์แล่ะเค้ร􀄙ืองปัั้นดินเผู้าเปั็นพื􀄚นท􀄙ีที􀄙มีีแนว โน้มีขีองการวิจัยท􀄙สีี ามีารถ้ำเปัิดเผู้ยขี้อมี้ล่เชีิ่งล่่กใหมี่ๆ เก􀄙ยี วกบัั มีรดกทางวัฒนธรรมีแล่ะเอกลั่กษณ์ ตอนน􀄚สีี ามีารถ้ำใชี่้ การเรียนร้เชีิ่งล่่ก (ปััญญาปัระดิษฐ์ร้ปัแบับัหน􀄙่ง) เพ􀄙อื ฝัึ่กโมีเดล่ที􀄙ทรงพลั่งให้จดจาำ ภาพศิิล่ปัะเค้ร􀄙อื งปัั้นดินเผู้าแล่ะหิน โดยอัตโนมีัติ เอาชี่นะขี้อจำากัดด้านทรัพยากร เชี่่น เวล่า กำาลั่งค้น แล่ะการขีาดเงินทุน บัทค้วามีนี􀄚แสีดงภาพรวมีเบัื􀄚อง ต้นแล่ะการพิสี้จน์แนวคิ้ดโดยให้แนวทางการเรียนร้ขีองเค้ร􀄙ืองตามีค้วามีก้าวหน้าในปััจจุบัันขีองการเรียนร้เชีิ่งล่่กเพื􀄙อฝัึ่ก โมีเดล่ให้จดจาำ ภาพขีองเค้ร􀄙อื งปัั้นดินเผู้าแล่ะศิิล่ปัะบันหินยุค้ก่อนปัระวัตศิิ าสีตร์ วิธีการเหล่่านี􀄚สีามีารถ้ำปัระมีวล่ผู้ล่ขี้อมี้ล่ จำานวนมีากได้อย่างรวดเร็วแล่ะแมี่นยำา เผู้ยให้เห็นร้ปัแบับัแล่ะค้วามีสีัมีพันธ์ใหมี่ๆ แมี้ว่า ML จะเปั็นงานที􀄙ซึั่บัซึ่้อน แต่ เค้ร􀄙อื งมีือใหมี่ๆ ทำาใหผู้้ ้ปัฏบัิ ัติงานทางโบัราณค้ดีท􀄙ีไมี่ใชี่่ผู้้เชีี่􀄙ยวชี่าญด้าน AI สีามีารถ้ำเขี้าถ้ำง่ ได้

Published: June 2024

Obesity is closely related to a decrease in brain-derived neurotrophic factor (BDNF) expression, which will pose a risk for metabolic disorders. Therefore, this study aims to prove the effect of moderate-intensity aerobic exercise on increasing BDNF expression in obese women. A total of sixteen obese women were selected based on predetermined criteria and were divided into 2 groups, namely the aerobic exercise group (AE) and the control group (CN). Aerobic exercise was carried out by running on a treadmill at moderate intensity (60-70 HRmax) for 40 minutes/session with a frequency of 5x/week for 2 weeks. Blood samples were taken twice before and after exercise intervention to see BDNF expression using the Enzyme-Linked Immunosorbent Assay (ELISA-kit) method. The results of the analysis showed differences in increase between the control group (1816.66 ± 689.48 vs. 1822.86 ± 467.87 pg/mL; p = 0.974) and the intervention group (2173.81 ± 705.89 vs. 3635.01 ± 699.71 pg/mL; p = 0.013). This shows that moderate-intensity aerobic exercise carried out for 2 weeks has proven effective in increasing BDNF expression in obese women.

Published: June 2024

In the current educational landscape, incorporating active learning activities centred around STEM (Science, Technology, Engineering, and Mathematics), themes have emerged as a potential solution for educators aiming to cultivate students' problem-solving skills. Nevertheless, a dearth of comprehensive research exists concerning the development of problem-solving skills specifically within the realm of STEM education. To bridge this gap, our study undertook a systematic review by utilizing relevant articles and implementing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Adhering to the prescribed steps within the PRISMA model, an extensive evaluation of 29 articles was conducted, spanning the period from 2018 to 2023, focusing on problem-solving skill development for students in STEM education. Through meticulous content analysis and synthesis, this research elucidated key insights pertaining to publication years and countries of origin, employed research methodologies, extracted keywords, identified limitations, and suggested avenues for future investigation. The findings revealed several influential factors that shape the cultivation of integrated teaching competence among students engaged in STEM education. This article bears significance for aspiring educational researchers, school administrators, and mainstream teachers vested in the exploration of this important subject matter.

Research introduction as a genre has been a fertile subject of inquiry in recent years. However, much of the research has focused primarily on the analysis of its generic structure, paying less attention to its other equally important elements. Hence, examining the quality of research introductions using multiple criteria, particularly among novice research writers, is pivotal in the field of second language (L2) academic writing in a secondary education context. This study was conducted to examine the writing quality of research introductions among senior high school (SHS) students and to further probe whether a significant difference existed in the students’ writing quality when grouped according to their chosen educational track. The data involved 60 research introductions collaboratively written and submitted as preliminary examination papers by SHS students in an online research writing course. Using a modified rubric from Tuyen et al. (2018), the research introductions were rated in terms of their content, organization, language use, mechanics, and citation, and were subjected to descriptive and inferential analyses. Triangulation using qualitative evidence was undertaken to illustrate the students’ actual writing quality. The results show that the overall writing quality of the students’ research introductions was poor, and there was a significant difference in their writing quality when they were grouped according to educational track. The results indicate a need for a more holistic theoretical framework on academic writing and a call for a genre-oriented approach to teaching academic writing in a secondary education context.
Towards Improving Class Attendance in Higher Education: A Case Study of a University of Technology in South Africa

Published: June 2024

The relationship between absenteeism and academic performance in the higher education environment is extensively documented. In the South African context, this was exacerbated by the institution of emergency measures at the outset of the COVID-19 pandemic and followed by hybrid adoption in the post-pandemic context. This study, relying on the views of sixteen academics from a university of technology in South Africa, explores the pandemic era considerations by examining pre-, during, and post-pandemic class attendance trends. By adopting a thematic lens, the study's outcomes highlighted a high prevalence trend in class non-attendance numbers from the academics’ viewpoint. Nevertheless, the relationship between attendance figures and students' performance was disproportionate as the academics witnessed slight differences in the performance levels of various categories of students, even in the context of the pandemic, a nuanced suggestion that certain pandemic-related interventions such as lecture recording could have been positively received. The study proposes strategies for potential implementation and suggests recommendations while advancing future research pathways.
Enhancing English First Additional Language Teaching and Learning in Grade seven Rural Classrooms: A Comprehensive Evaluation of Teaching Strategies
Authors: Nqoma Lungiswa
Published: June 2024

Language used for teaching and learning (LoLT) is considered as the essential tool that drives learning in classrooms. When the language of teaching and learning is not the mother tongue (MT) it becomes a barrier to teaching and learning. This study aims to evaluate strategies that can be employed to foster teaching and learning in English First Additional Language (EFAL) classrooms. The study employed a qualitative research method through case study design. Data was collected through semi-structured interviews and class observations; it made use of purposive sampling which involved ten educators and seven learners from grade seven classrooms. Thematic analysis approach was adopted to analyse the collected data and themes were extracted. Findings of this paper showed that language as medium of instruction (MoI) plays a crucial role in teaching and learning, and the confusion could lead to a mismatch of concepts and ideas when it is different from learners’ and educators’ home languages. This requires EFAL educators to possess specific first additional language teaching competencies, skills, and an extremely high sense of personal linguistic proficiency in the language of instruction (LOI). The paper, therefore, recommends that to improve EFAL learners’ performance, language educators must utilise conceivable teaching and learning strategies that would be relevant to the subject, content, topics, and class activities. It was also recommended that EFAL learners be exposed to language learning programs that would develop and improve basic language skills in the targeted language. Educators are encouraged to use handcrafted teaching resources and DoE renovate infrastructure and provide basic resources.

Educators are becoming concerned about the students’ increasing dependency on diverse digital technologies in their daily lives, which creates a clear disconnection between their lifestyles and the passive teaching and learning strategies implemented in schools. Thus, contemporary research debates focus on enhancing learning environments to maintain the interests and motivation of students. Educationists have proposed strategies such as integrating immersive and engaging digital technologies into the classroom to foster shared learning experiences among students. Although augmented reality (AR) is a fascinating immersive technology, its integration into the classroom environment has been scarcely documented. With this perspective, the present study seeks to amalgamate AR technology and Kolb's Experiential Learning Model (ELM) into an enhanced experiential learning classroom by using a mixed-method research methodology. Both qualitative and quantitative approaches were used to conduct this study on undergraduate students enrolled in a digital marketing course at a Malaysian institution. Data were collected through surveys, interviews, and open-ended questions, with consideration given to the student’s experience within this technologically assisted learning environment. Significant data analysis and feedback demonstrated an effective student collaboration, which improved learner interest, motivation, and engagement, thereby establishing a solid case for the integration of immersive technologies, such as AR, into the educational process to create an enhanced learning environment. Thereby, this paper presents the ARSSLE (AR-supported Shared Learning Experiences) framework, which may assist teachers in building a captivating yet collaborative and dynamic learning environment.

In ensuring that TVET colleges achieve their mandate of academic excellence, the role of leaders as instructional leaders becomes critical and relevant. This study explores challenges experienced in implementing instructional leadership practices within selected TVET colleges of South Africa. In addressing this objective, a qualitative approach was employed. About three campus managers, six heads of departments and six lecturers participated in the study. These participants were drawn from four colleges that were purposively sampled. Data were collected through in-depth interviews, focusing on practices of instructional leadership by campus managers and challenges experienced thereof. The collected data were analysed, using thematic analytical approach. This was to identify and categorise participants’ responses from interviews and generated key themes were then interpreted. Results showed that externally, campus managers faced challenges related to lack of time, work overload and lack of rewards or incentives. Internally, campus managers had limited skills and knowledge on instructional leadership. The study, therefore, recommended that campus managers be trained on instructional leadership and develop a culture of delegating mainly administrative duties than instructional duties to their immediate subordinates. This would allow campus managers to have more time to monitor teaching and learning as part of their instructional leadership practices.
Plane sections method in determining characteristic velocities of water flow in construction and operation of underwater crossings

При строительстве и эксплуатации подводных переходов магистральных трубопроводов через реки необходимо иметь достоверные сведения о скоростях речного потока и их распределении в поперечном сечении русла в заданный момент времени. Применяемые в действующих нормативных документах понятия «скорость», «средняя скорость», «максимальная скорость» течения (потока) не дают понимания особенностей распределения частных скоростей течения и расходов воды по поперечному сечению водотока, что в ряде случаев принципиально важно при решении задач строительства и эксплуатации подводных переходов. В настоящей статье представлен подход, позволяющий на основании результатов полевых гидрометрических работ получить с достаточной точностью данные по скоростной структуре водного потока и общую пространственную картину скоростной неоднородности потока по сечению русла реки. Основой данного подхода является разработанный выдающимся российским и советским ученым-гидрологом М. А. Великановым метод плоских сечений, который построен на очевидных аналитических зависимостях гидравлики и использовании стандартных гидрологических исходных данных. Приведенный авторами опыт практического применения метода плоских сечений для решения прикладных гидрологических задач позволяет рекомендовать его для использования при разработке проектных и технических решений по строительству и эксплуатации подводных переходов.

During the construction and operation of undewater crossings for main pipelines across rivers, we need to have reliable information about the river flow velocities and their distribution in the riverbed cross section at a given point in time. The concepts of ‘‘velocity’’, ‘‘average velocity’’ and ‘‘maximum velocity’’ of the flux (flow), as used in current regulatory documents, do not provide a clear understanding of the distribution specifics for particular flow velocities and water flow rates in the watercourse cross section which, in some cases, is fundamentally important for solving problems related to the construction and operation of underwater cros-sings. This paper presents an approach that allows for obtaining fairly accurate data on the velocity structure of water flow and a general spatial pattern for the flow velocity heterogeneity in the riverbed cross section based on the results of field hydrometric survey. The basis of this approach is the plane section method developed by the outstanding Russian and Soviet hydrologist M. A. Velikanov, which is based on obvious analytical dependencies in hydraulics and the use of standard hydrological input data. The authors’ experience in the practical application of the plane section method for solving applied hydrological problems allows us to recommend it for use in the development of design and engineering solutions for construction and operation of underwater crossings.

The study of light-dependent growth of butch culture Phaeodactylum tricornutum has been carried out. Based on the developed mathematical model of the true absorption spectrum, an express method for determining the concentration of photosynthetic pigments without interfering with the growth process of the culture was proposed. In the exponential phase at an irradiance of 120 μE·m-2·s-1, the maximum specific synthesis rates of chlorophylls a and c were determined, which were 1,4 times higher than
the specific growth rate of the culture and amounted to 0,3 day-1. On the eighth day of the experiment, a kink in the growth curve was observed, which was expressed as a decrease in both growth rate and chlorophyll production. At the transition to the linear growth phase, the maximum productivity of Pheodactylum was 0,15 g·l-1·day-1, and chlorophyll production was 3,44 and 2,85 mg·l-1·day-1 a and c, respectively. The dependence of the integral light absorption coefficient on chlorophyll a concentration was obtained, which is described by the Bouguer-Lambert-Bera law with a sufficient degree of accuracy;
the specific light absorption coefficient was 0,10 m2·g-1 dry matter and 0,008 m2·mg-1 chlorophyll a. Comparison of the results obtained with literature data showed that at irradiances of 120 μE·m-2·s-1 and 602 μE·m-2·s-1 the specific rates of chlorophyll a synthesis are the same, and the maximum specific growth rate of Ph. tricornutum culture increases proportionally with increasing light intensity from 0,23 to
0,91 day-1. The results obtained indicate that chlorophyll a synthesis is determined not by the effective light intensity, but by the amount of reserve biomass accumulated during the previous light period.
