<title>Cerium-containing counter electrodes for transparent electrochromic devices</title>
1997
Films of Me-Ce oxide (Me: Ti, Zr, Sn, W) and of Ni-Ce hydroxide were produced by reactive magnetron co-sputtering. Li intercalation in Me-Ce oxide, and H exchange in Ni-Ce hydroxide, were accomplished electrochemically. Electrochromism was quenched in proportion with the Ce content in Me-Ce oxide. Films of Zr-Ce (and to some extent Ti-Ce) oxide were able to serve as fully transparent counter electrodes, of much interest for transparent electrochromic devices. In Ni-Ce hydroxide, the Ce addition enhanced the capacity for charge exchange.
Mākslinieciskās izteiksmes līdzekļi rakstos par ekonomiku
2022
Šajā bakalaura darbā tiek pētīts stilistisko ierīču lietojums un to nolūks The Economist laikrakstu rakstos par ekonomiku. Šajā darbā izmantotā pētījuma metode ir diskursa analīze, balstīta uz Galperina (1977) stilistisko ierīču klasifikāciju. Darbā apskatīta stilistikas kā nozares izcelsme, attīstība un klasifikācija. Pētījuma rezultāti liecina, ka žurnālistikā par ekonomiku tiek izmantotas dažādas stilistikās ierīces, un visbiežāk izmantotās stilistiskās ierīces kā spriedze, citāti, metaforas un aliterācija. Papildus tam tiek secināts, ka tekstā esošie līdzekļi palīdz rakstos izmantotajā valodā izcelt dramatisku efektu, kā arī sniegt tekstam papildus informāciju.
Kohēzija biznesa runās
2018
Šis bakalaura darbs pēta kohēzijas līmeni Maska un Mejas un Abes runās par komercdarbību. Darba mērķis ir izpētīt kohēzijas līdzekļu lietojumu runās par komercdarbību. Kā pētijuma metodes darbā izmantots literatūras apskats par dažādiem publicētajiem avotiem par leksisko un gramatisko kohēziju un biznesa diskursu, kā arī biežuma analīze. Leksiskās kohēzijas, atsauces, un saikļa klātbūtne tika analizēti trīs runās un trīs runās struktūras daļās. Analīzes rezultāti parādīja, ka iepriekš minēto kohēzijas līdzekļu izmantošanas biežums ir diezgan vienāds. Tomēr var secināt, ka saiklis ir visizplatītākais kohēzijas līdzeklis analizētajās runās par komercdarbību.
Imperial straightening devices in disciplinary choices of academic knowledge production
2021
Abstract In this piece, the authors question whether critical language research, in its complex collection of researcher choices, is possible beyond the discursive imaginary of critical academic scholarship. In other words, how do (allegedly) anticolonial efforts re-orient towards contribution to the imperial record? We present three vignettes, through which we grapple with the notion that researcher choice exists within the solipsism of academia. In doing so, we frame research and scholarship as a collection of choices, which we believe are better understood as a collection of fraught dilemmas. These dilemmas recognize that all academic scholarship production and its processes are birthed …
Beyond good and evil: The impact of digital environment in family life
2019
Internet has changed the way we interact with others and has become an essential tool for daily activities. Children and adolescents are the main users of new digital technologies and their first contact with a screen happens increasingly earlier in life. Its premature use can be dangerous: technology represents a “supernormal stimulus” that can act on the brain reward circuit and affect neural development. In this article we describe the effects of technology on the brain, well-being, social and family relationships, highlighting both positive and negative ones: rather than defining a priori any type of technology as “good” or “bad”, we should consider how specific applications are used in…
Au-delà de la frontière : la Charte de Lampedusa, un exemple de réécriture des droits contre la logique de l’enfermement
2015
The paper describes the elaboration of the Charter of Lampedusa. It focuses on the political and geopolitical upheavals of 2014, paying particular attention to the evolving humanitarian-military devices of border management and controls deployed in the Euro-Mediterranean area. Borders are analyzed not only with respect to their function of geographic separation, but also as social, cultural, and economic markers. The objectives and limits of the Charter are explored in light of its capacity to represent an alternative vision against the political, economic, social and cultural predominant model in Europe. It is argued that this model needs to be completely restructured. The alternative visi…
Thermodynamics and Biophysics of Biomedical Nanosystems Applications and Practical Considerations
2019
This book highlights the recent advances of thermodynamics and biophysics in drug delivery nanosystems and in biomedical nanodevices. The up-to-date book provides an in-depth knowledge of bio-inspired nanotechnological systems for pharmaceutical applications. Biophysics and thermodynamics, supported by mathematics, are the locomotive by which the drug transportation and the targeting processes will be achieved under the light of the modern pharmacotherapy. They are considered as scientific tools that promote the understanding of physicochemical and thermotropic functionality and behavior of artificial cell membranes and structures like nanoparticulate systems. Therefore, this book focusses …
Retos y oportunidades de la tecnología móvil en la educación física (Challenges and opportunities of mobile technology in physical education).
2019
La educación física (EF) y su profesorado están llamados a seguir procesos de inmersión digital, voluntarios o involuntarios, asociados al consumo masivo de medios y servicios digitales y a las demandas de la sociedad y de la institución educativa. El uso de tecnología, especialmente la móvil, social y ubicua, se generaliza personal y profesionalmente, aunque la escuela sigue sin encontrarle acomodo. Reconoce su potencial didáctico, pero no logra alcanzarlo. En la EF el uso de tecnologías tradicionales y fijas han demostrado su utilidad en la fase preactiva y postactiva del acto didáctico, sin embargo, los aprendizajes en movilidad propios de la fase activa, aconsejan explorar alternativas …
Digital Devices Use and Language Skills in Children between 8 and 36 Month
2020
Background: Over the past decade, the use of digital tools has grown and research evidence suggests that traditional media and new media offer both benefits and health risks for young children. The abilities to understand and use language represent two of the most important competencies developed during the first 3 years of life through the interaction of the child with people, objects, events, and other environmental factors. The main goal of our study is to evaluate the relationship between digital devices use and language abilities in children between 8 and 36 month, also considering the influence of several factors. Materials and Methods: We conducted a cross-sectional observational stu…
Secondary Education Students’ Questions on Experimental Devices
2012
Las preguntas forman parte esencial del trabajo que desarrollan los científicos para construir nuevo conocimiento. Sin embargo, los alumnos formulan un número muy escaso de preguntas en las situaciones usuales de aula. En este trabajo se realiza una revisión de las investigaciones realizadas sobre génesis de preguntas y se describen tres estudios empíricos realizados con estudiantes de diferentes niveles educativos ante dispositivos experimentales. Los objetivos fueron: 1) Estimular y analizar las preguntas de los estudiantes cuando intentan comprender los dispositivos; 2) Contrastar la idea de que la mayoría de preguntas destinadas a obtener información tienen su origen en inferencias fall…
