Оцінка етанологенного потенціалу ксилозоферментуючих дріжджів Scheffersomyces stipitis UCM Y-2810
No full textBackground. Enhancing the efficiency of second-generation (2G) bioethanol production from lignocellulosic biomass is crucial for advancing sustainable biofuel technologies. However, the conversion of biomass into 2G bioethanol faces substantial challenges, necessitating a comprehensive investigation of microbial agents. Objective. To evaluate the effect of glucose and xylose concentrations, as well as cultivation duration, on the efficiency of ethanologenesis using the model organism Scheffersomyces stipitis UCM Y-2810, and to determine the optimal conditions for achieving maximum ethanol yield. Methods. The effects of glucose and xylose concentrations and cultivation time on ethanologenesis efficiency were evaluated using S. stipitis UCM Y-2810 as a model organism. The experimental design included three levels of factors: xylose concentration (3, 16.5, and 30 g/l), glucose concentration (1, 5.5, and 10 g/l), and cultivation durations (1, 2, and 3 days). Statistical analysis of the experimental data was conducted using a three-factor, three-level Box–Behnken design. Results. Under submerged cultivation of the strain of S. stipitis UCM Y-2810 in model media, optimization of the ethanologenesis process resulted in a maximum ethanol yield of 7.74 g/l. The optimal conditions for this yield were identified as follows: xylose concentration of 16.5 g/l, glucose concentration of 7.75 g/l, and a cultivation time of 3 days. Conclusions. The application of the Box–Behnken design revealed that the statistically significant factors influencing ethanologenesis efficiency were xylose concentration, yeast cultivation duration, and the linearquadratic interaction between these two factors.Проблематика. Підвищення ефективності виробництва біоетанолу другого покоління (2G) з лігноцелюлозної біомаси має вирішальне значення для розвитку сталих біопаливних технологій. Однак перетворення біомаси на біоетанол 2G стикається зі значними труднощами, що зумовлює необхідність всебічного дослідження мікробних агентів. Мета. Оцінити вплив концентрації глюкози, ксилози та тривалості культивування на ефективність етанологенезу при використанні Scheffersomyces stipitis UCM Y-2810, а також визначити оптимальні умови для досягнення максимального виходу етанолу. Методика реалізації. Оцінку впливу концентрації глюкози, ксилози та тривалості культивування на ефективність етанологенезу проводили з використанням S. stipitis UCM Y-2810 як модельного організму. Експериментальний дизайн включав три рівні факторів: концентрація ксилози (3, 16,5 і 30 г/л), концентрація глюкози (1, 5,5 і 10 г/л) і тривалість культивування (1, 2 і 3 дні). Статистичний аналіз отриманих результатів здійснювали з використанням трифакторного, трирівневого експериментального дизайну Бокса–Бенкена. Результати. При глибинному культивуванні штаму S. stipitis UCM Y-2810 на модельних середовищах оптимізація процесу етанологенезу дала змогу досягти максимального виходу етанолу 7,74 г/л. Оптимальними умови для досягнення цього виходу були: концентрація ксилози 16,5 г/л, концентрація глюкози 7,75 г/л і тривалість культивування 3 доби. Висновки. Застосування дизайну Бокса–Бенкена показало, що статистично значущими факторами, які впливають на ефективність етанологенезу, є концентрація ксилози, тривалість культивування дріжджів та лінійно-квадратична взаємодія між цими двома факторами

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textFor the first time cw, cascade lasing was demonstrated in 1% Er doped yttrium lithium fluoride (YLF) at room temperature at both 1620 and 2810 nm. In addition, cw lasing in Er[1%]:YLF at 1640 nm and in Er[5%]:YLF at 2810 nm at room temperature is reported for the first time in material of such low concentration
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
