Authors: Zu Yuqian , Zong Mengyu , Wang Yangxiao , Zhang Zhen , Zhang Zhonghan , Wu Anhua , Liu Jie , Su Liangbi
Published: September 2020

Self-Q-switched lasing was demonstrated for the first time around 2 μm in Thulium (Tm) doped CaF2 single-crystal fiber (SCF) using a compact linear cavity. Maximum average output power of 1.17 W was obtained under 2.38 W absorbed pump power, corresponding to the slope efficiency of up to 56.01%. Self-Q-switched laser with a 1.736 μs shortest pulse width at 48.80 kHz repetition rate was successfully realized. Besides, broad wavelength-tunable Tm:CaF2 SCF laser in 1859–2040 nm region was operated. These results show that the Tm:CaF2 SCF is a promising alternative for generating efficient micro diode-pumped pulsed lasers at 2 μm.

Authors: GÜVENALP Neşe , GÜVENÇ Dilek
Published: September 2020

Cancer cells are characterized by increased glucose uptake and the production of lactate, which leads to acidification of the tumor microenvironment. This acidification facilitates the development of invasiveness and metastasis. In this study, we investigated the effects of medium pH manipulation on the proliferation and viability of human hepatocellular carcinoma (HepG2) cells in vitro. HepG2 cells were grown in media with pH ranging from 6.0 to 8.5 for 24 h. The cells were then subjected to WST-1 and trypan blue exclusion assays to evaluate viability and cell proliferation, respectively. At pH 6.8 and 6.6, HepG2 cell viability was not significantly different from the control group (pH 7.2) (p>0.05) but there was a significant decrease at pH 6.4, 6.2 and 6.0 (p < 0.05). Furthermore, there was a significant decrease in cell viability at pH’s 7.8, 8.0 and 8.5 (p0.05), and decreased at pH 7.6 and 7.8 (significant at pH 7.8; p

Published: September 2020

Este artigo objetiva compartilhar experiências de formação de professores de línguas estrangeiras ao longo de propostas que viabilizaram o estágio supervisionado, obrigatório nos cursos de licenciatura em Letras, na modalidade remota. As propostas surgiram da demanda por ações educacionais não-presenciais em função da Pandemia Covid-19, responsável pela suspensão do ano letivo presencial na Universidade Federal do Paraná (UFPR - Brasil). Os resultados iniciais deste estudo, de cunho etnográfico, partem de nossas percepções, como professoras formadoras, responsáveis pelas ações, e dos licenciandos que participaram das experiências remotas de prática de docência e estágio supervisionado, considerando crenças pessoais sobre ensinar-aprender línguas por meio de novas tecnologias. Nossas discussões sobre tais percepções fundamentam-se nas concepções sobre estágio e pesquisa no estágio, de Pimenta e Lima (2011), nas perspectivas  de Schön (1994), Tardif e Moscovo (2018) quanto à formação reflexiva de professores, nas visões de Garcia da Cunha (2016) e Nogueira (2011) sobre práticas colaborativas de coensino e coaching e em discussões de Wenger (1998) e Walesko (2019) sobre comunidades de prática.  A partir dessas experiências, percepções e reflexões, apresentadas no texto, sugerimos perspectivas e possibilidades de inclusão e utilização das novas tecnologias nas ações de formação docente na modalidade remota, na já citada universidade e em outras instituições de ensino superior do país.

Theodor Wolff: ,,Tagebuch meines Sohnes“. Zugleich ein Ausblick auf die Tradition des Elterntagebuches seit der Aufklärung1
Authors: Reinthal Von Angela
Published: September 2020

Der Wunsch und das ,,Bedürfniss, mich mit dir zu unterhalten“ (S. 55)2 veranlassen Theodor Wolff (1868–1943), 1906 bis 1933 Chefredakteur des ,,Berliner Tageblatts“, an sein erstgeborenes Kind Richard wenige Tage nach dessen Geburt einen langen Brief
in Gestalt eines Vatertagebuches zu beginnen, den er erst sieben Jahre später abbricht – der letzte Eintrag ist vom 1. August 1913 (S. 124–126). In dieser Zeit sind zwei weitere Geschwister, Rudolf und Lilly, hinzugekommen, und bedingt durch den Ersten Weltkrieg mußte
der an sich schon vielbeschäftigte politische Journalist seine Aufmerksamkeit vollständig der Schilderung des Weltgeschehens widmen. Im Folgenden sollen die Tradition, in der das Wolff’sche Tagebuch steht, sowie die Ausprägungen dieser Gattung mit Schwerpunkt auf dem Vatertagebuch
vorgestellt werden, dies vor allem im Hinblick darauf, wo es sich in diese Gattung einfügt und wo es davon abweicht. Ein Fazit läßt sich hier schon ziehen: Das Wolff’sche Tagebuch berichtet wie alle Elterntagebücher vom Aufwachsen des Kindes bzw. der Kinder mit allen
dazugehörenden Ereignissen und Erlebnissen, ist aber bei weitem nicht so ,,buchhalterisch“ angelegt wie manche anderen Diarien. Die auch durch die großen Pausen bedingte Distanz sowie Wolffs journalistische Sprachbegabung ermöglichen die Entstehung eines Textes, der sich
einerseits durch einen fesselnden, oft ironischen und auch poetisch anspruchsvollen Stil auszeichnet, sich dadurch von anderen Elterntagebüchern abhebt, sich aber andererseits durch die Beobachtung der Kindesentwicklung und vor allem durch die in allen Zeilen durchschimmernde und auch
offen formulierte liebevolle Zuneigung in die Tradition einbettet.
Industrial Policy Strategy: A Case of Changing National Priorities in Russia
Authors: Romanona Olga A. , Kuzmin Evgeny A.
Published: September 2020

New technology trends, mainly related to the development of Industry 4.0 and the digital economy, have created significant prerequisites for changing the priorities of industrial policy. This topic is particularly relevant for countries with economies in transition or developing economies, including Russia. The accumulated structural gap, expressed in the level of industries' digitalization, indicates a low willingness of industrial enterprises to introduce digital and related advanced technologies. The data obtained show that this gap is especially pronounced (more than 50% of the average for the EU countries) in the manufacturing industry, oil and gas industry, and transport. In mining, this gap approaches 70%. These circumstances predetermined the need to identify the strategic vector of Russian industrial policy against the background of the developing modern technologies that predetermine the adjustment of industrial policy priorities. To assess the potential of industrial transformation, the authors conducted a comparative analysis of changed targets for the formation of industrial policy in the developed countries and Russia. The analysis showed a sharp evolution in the priorities of industrial policy in Russia – those changed six times during the period from 2014 through 2019. The strategic policy focus has shifted from supporting projects in the production of high-tech civilian and/or dual-use products by enterprises of the military-industrial complex and the transition of enterprises to the best available technologies to supporting the digital economy and artificial intelligence technologies. Based on the results, the researchers suggested the development of industrial policy instruments adapted to the new priorities.

Published: September 2020

Research into the behavioral and neural correlates of spatial cognition and navigation has benefited greatly from recent advances in virtual reality (VR) technology. Devices such as head-mounted displays (HMDs) and omnidirectional treadmills provide research participants with access to a more complete range of body-based cues, which facilitate the naturalistic study of learning and memory in three-dimensional (3D) spaces. One limitation to using these technologies for research applications is that they almost ubiquitously require integration with video game development platforms, also known as game engines. While powerful, game engines do not provide an intrinsic framework for experimental design and require at least a working proficiency with the software and any associated programming languages or integrated development environments (IDEs). Here, we present a new asset package, called Landmarks, for designing and building 3D navigation experiments in the Unity game engine. Landmarks combines the ease of building drag-and-drop experiments using no code, with the flexibility of allowing users to modify existing aspects, create new content, and even contribute their work to the open-source repository via GitHub, if they so choose. Landmarks is actively maintained and is supplemented by a wiki with resources for users including links, tutorials, videos, and more. We compare several alternatives to Landmarks for building navigation experiments and 3D experiments more generally, provide an overview of the package and its structure in the context of the Unity game engine, and discuss benefits relating to the ongoing and future development of Landmarks.

The research will find out the actant model and functional model to see the plots, characters and hidden aim inside the text. The research also sees Richard Krevolin's Scene-o-gram model to sharpen the plot and characters in the film. The results of the study show that the six actants in the Greimas model are mentioned as subject, object, sender and recipient showed the meaning of the struggle against patriarchal domination that occurs throughout the story with violence and emotion as the main traitors and female characters who are the helpers of the main characters in achieving their desires. Meanwhile, a conflict-filled storyline can be read in a functional scheme that tells the beginning, the transformation that contains conflict until the final situation as the end of the story in the film. From the semiotic square, it can be found that the inner structure which is the main theme in this film is about masculine versus feminine as a simple movement of feminism to fight the gap among gender and ethical versus indelicate as a reflection of eastern Indonesian culture

A 25-year-old pregnant woman with a history of five previous miscarriages was admitted to our clinic. She had undergone abortion in her first pregnancy at 14 weeks gestation due to anhydramnios. Her second pregnancy had ended in a miscarriage at 19 weeks gestation due to premature rupture of membranes. Both of her first two pregnancies showed normal karyotypes. Her third pregnancy was noted to be an ectopic pregnancy leading to abortion at 5 weeks gestation. Afterwards, she experienced two more miscarriages at 7 weeks of gestation due to the lack of fetal cardiac activity which could not been investigated for chromosomal abnormalities. Her current pregnancy was also terminated at 9 weeks of gestation due to the lack of fetal cardiac activity. Cytogenetic analysis of abortion material using GTG banding technique revealed 48,XY,+12,+15[5]/46,XY[25] karyotype (7). Both parents were found to have normal karyotypes and physical examinations showed no obvious abnormalities. Thrombophilia evaluation revealed that she had heterozygous MTHFR C677T polymorphism.

La Constitution de 1958 : une conception de l’État
Authors: Denoix de Saint Marc Renaud
Published: September 2020

La Constitution du 4 octobre 1958 porte la marque de la personnalité du général de Gaulle et de ses convictions en matière institutionnelle, au premier rang desquelles la nécessité de restaurer l’autorité de l’État. En donnant notamment un statut particulier au président de la République – désigné, dès avant la révision de 1962, comme « la clef de voûte » des institutions – et en instaurant le parlementarisme rationalisé, elle a su doter la France d’un État souverain, unitaire et efficace.
De Gaulle face aux électeurs
Authors: Jaffré Jérôme
Published: September 2020

Le rapport du général de Gaulle aux électeurs et aux élections est complexe. Le Général considère la consultation des électeurs par référendum comme une manifestation supérieure de la démocratie. Mais il apprécie beaucoup moins les élections, soit parce qu’elles donnent trop de place aux partis politiques, soit parce qu’il accepte difficilement pour lui-même le statut de candidat et la compétition électorale.
Le Général et l’Histoire
Authors: Sirinelli Jean-François
Published: September 2020

Le général de Gaulle n’est pas seulement une figure majeure de l’histoire française, il y est doublement présent : non seulement, bien sûr, par la forte empreinte directe qu’il y a posée, mais aussi par la trace mémorielle très dense qu’il y a laissée. Ce sont donc bien deux strates, à la fois distinctes et imbriquées, qu’il convient de sonder pour rendre compte de cette place gaullienne dans notre histoire nationale.
De Gaulle rétrograde ? Le cas de la pilule
Authors: Mossuz-Lavau Janine
Published: September 2020

Contrairement à l’image qu’on peut avoir de lui, de Gaulle n’était pas réellement rétrograde en matière de mœurs. En dépit des avis très conservateurs de certains ténors de sa famille politique, il a donné son accord pour la légalisation de la contraception dite moderne. Ce qui a permis, en 1967, le vote de la loi Neuwirth et l’accès des Françaises au diaphragme, à la pilule et au stérilet.
Polysaccharide source altered ecological network, functional profile, and short-chain fatty acid production in a porcine gut microbiota

Published: September 2020

Several validated dynamic in vitro models of the colon have been developed for humans, but there is no dynamic in vitro fermentation model for pigs. This study was conducted to modify the human, dynamic, computer-controlled TNO in vitro model of the colon (TIM-2) for pigs and investigate effects of different starch sources and polysaccharides on swine microbiota structure, ecological network, predictive functional profile, and short-chain fatty acids production. Our study showed that three different types of starch or two polysaccharides greatly impacted microbiota composition. Co-occurrence network analysis indicated that microbiota fed with different sources of starch changed the network topological properties. Functional profiles were predicted to vary significantly among the three starch treatments, and the original pig faecal inoculum was more similar to maize starch treatment. On the other hand, compared with maize starch and arabinoxylans (AX), the microbial composition of the original inoculum was more similar when AX-XG (arabinoxylans and xyloglucan) were added, and the functional profile of the original inoculum also clustered with AX-XG. The cumulative production of acetic, propionic, and butyric acid on maize starch were significantly higher than those on potato starch and wheat starch, while only the amount of acetic acid was significant higher on AX-XG than that on AX. In conclusion, supplementation of maize starch as the starch source together with AX and XG, leads to the bacteria being more stable in the in vitro model and closer to the original inoculum and microbial function compared to potato starch, wheat starch and AX. A maize basal diet may improve energy absorption in the large intestine in growing pigs.
Apport du portfolio numérique d'apprentissage et de la vidéo pour l'autoévaluation de la compétence en production orale d'élèves du secondaire en classe de français, langue d'enseignement
Authors: Paquet Maxime , Karsenti Thierry
Published: September 2020

Cette étude part du constat que nous savons peu de choses sur l'utilisation du portfolio numérique et sur le recours aux autoévaluations dans un contexte d'apprentissage de la production orale. De ce constat découle notre cadre théorique, élaboré autour des modèles didactiques de l'oral (Dumais, 2010a ; Lafontaine, 2007) et des données empiriques portant sur l'utilisation du portfolio numérique et de l'autoévaluation, auxquels nous souhaitons apporter de nouvelles données grâce à notre recherche, dont l'objectif est de décrire et d'analyser l'apport du portfolio numérique pour l'autoévaluation de la compétence orale d'élèves du secondaire. Pour atteindre cet objectif, nous avons analysé globalement les autoévaluations contenues dans les portfolios et les réponses à deux questionnaires de 77 élèves de 3ème secondaire (N = 77), puis, de manière plus précise, nous avons analysé le contenu des autoévaluations de 16 de ces élèves (N = 16), qui ont également participé à une entrevue individuelle. Notre collecte de données nous a permis de décrire de quelle manière le recours au portfolio numérique d'apprentissage permettait d'accroître la capacité des élèves à s'autoévaluer.
Software-Defined Networking (SDN)
Authors: Reddy L. Naga Durgaprasad
Published: September 2020

This chapter researches in the area of software-defined networking. Software-defined networking was developed in an attempt to simplify networking and make it more secure. By separating the control plane (the controller)—which decides where packets are sent—from the data plane (the physical network)—which forwards traffic to its destination—the creators of SDN hoped to achieve scalability and agility in network management. The application layer (virtual services) is also separate. SDN increasingly uses elastic cloud architectures and dynamic resource allocation to achieve its infrastructure goals.

This chapter provides readers with a practical and experimental approach that is based on the author's education and extensive experiences. These experiences are drawn from a journey of different levels of delivering competency-based learning to education and industry in South Africa. The author provides a perspective of interpretation for the utilization of a behavioral approach to competencies development in organizational environments. The author proposes learning occurs because of a behavioral approach to understanding competencies as a concept.
Robot-Proof Work Capabilities
Authors: George Richard A. , Bowles Marcus , Nouri Nicholas , Bhargava Ria
Published: September 2020

Jobs are changing fast as many firms automate or augment work-tasks. Constant change is the new normal as technology relentlessly infiltrates all industries and businesses. This puts pressure on employees to upskill and stay relevant. While some jobs are relatively immune from disruption, these are in the minority. Most employees will need to continually build the necessary skills and capabilities that will help them safeguard their current careers or shift to entirely new careers or industries. This chapter describes an approach to answer the following question: What are the core work capabilities that students and employees should be learning now to future-proof their careers? The authors apply a prediction of automation and augmentation to work-tasks to model the change to the future workforce and analyse the remaining work skills and abilities required in the future. These future skills and abilities are further grouped to determine 32 future-work capabilities, including 13 digital and data literacies that can be targeted by employees, firms, and governments in L&D programs.
