Adsorption of anionic dyes onto natural, thermally and chemically modified smectite clays
2014
Abstract The aim of this study was to determine the adsorption capacity of the smectite clays (from the overburden of the lignite deposit in Belchatow) for two anionic dyes, i.e. Reactive Blue 81 (RB-81) and Direct Blue 74 (DB-74). Additionally, the influence of the thermal and chemical (acid and alkali) clay modifications on the amount of bonded dyes was investigated. The adsorption capacity of the clay (natural and modified) was different for studied dyes and depended on the initial concentration and modification type. All the modified clays adsorbed the dyes at pH>pHPZC as the negatively charged surfaces of their particles (in accordance with the formula: AOH ↔ AO- + H+) prevented the…
Splines in convex sets under constraints of two‐sided inequality type in a hyperplane
2008
The problem of minimization of a smoothing functional under inequality constraints is considered in a hyperplane. The conditions of the existence of a solution are obtained and some properties of this solution are investigated. It is proved that the solution is a spline. The method for its construction is suggested. First Published Online: 14 Oct 2010
Multispectral filter arrays: Recent advances and practical implementation
2014
Thanks to some technical progress in interferencefilter design based on different technologies, we can finally successfully implement the concept of multispectral filter array-based sensors. This article provides the relevant state-of-the-art for multispectral imaging systems and presents the characteristics of the elements of our multispectral sensor as a case study. The spectral characteristics are based on two different spatial arrangements that distribute eight different bandpass filters in the visible and near-infrared area of the spectrum. We demonstrate that the system is viable and evaluate its performance through sensor spectral simulation. Multispectral filter arrays: Recent advan…
Aristóteles entre doxografía y biografía: sobre Diógenes Laercio V 31
2019
Se pretende llamar la atención sobre un par de frases que aparecen justo hacia la mitad de la controvertida doxografía de Aristóteles que se puede leer en las Vidas y doctrinas de los filósofos más ilustres de Diógenes Laercio V 31, y que desde luego no corresponden a ningún sistema doxográfico conocido. Como sucede no pocas veces en la obra laerciana, la misma apreciación sobre si el filósofo debe o no enamorarse y contraer matrimonio se repite idéntica en otras doxografías completamente distintas: la cirenaica (DL II 91), la estoica (DL VII 129) y la epicúrea (DL X 118). Cabe plantearse, pues, el origen de este interés, en varias doxografías, por la vida sentimental, podríamos decir, de l…
The Development of Teachers' and Their Students' Social and Emotional Learning During the “Learning to Be Project”-Training Course in Five European C…
2021
This study was funded by a project Learning to Be: Development of Practices and Methodologies for Assessing Social, Emotional and Health Skills within Education Systems (#4120034) in the framework of Erasmus+ KA3 program (582955-EPP-1-2016-2-LT-EPPKA3-PI-POLICY). We are also grateful for funding by the Academy of Finland (#308352) and Finnish Strategic Research Council (#327242).
A firm's activity in social media and its relationship with corporate reputation and firm performance
2015
There is growing debate about whether companies’ investments in social media really pay off. This research attempts to contribute to this discussion by investigating the relationship between a firm’s social media activity and two outcomes, namely, company reputation and firm financial performance. Two propositions are developed based on theory and tested with a sample of 59 companies. The findings suggest that a firm’s social media activity is only partially linked with its financial performance and is not linked with corporate reputation. The implications of the research suggest that little is known about the relationships between a firm’s social media activity and corporate reputation and…

The social mediators: limits and challenges of a system
2011
Following a study aimed at measuring the limits and challenges of the social mediation system, the authors put forward an examination in this article of the mutual expectations of the social mediator and its employer, the urban community. This sociological study is comprehensive: it uses the method of the individual interview and focus group. The analysis of the results is supported by contributions from Boltanski and Thévenot in order to compare the reference “worlds” of both types of actor. It is supplemented by the analysis of notions of “system” (Foucault) and “professionalisation” (Hainaux et al., Bartoli). The authors try to understand the extent to which the actors understand involve…
Sociālā tīkla „Facebook” uzdevumi mājasdarbu izpildes sekmēšanai angļu valodas stundās 7. klasē
2015
Diplomdarba autores pieredze liecina, ka ļoti bieži daudzi skolēni neizpilda mājasdarbus, aizmirst tos izpildīt, vai arī skolotājam ir nepieciešams atgādināt, lai mājasdarbs tiktu veikts. Iekļaujot mācību procesā uz internetu balstītas aktivitātes skolēniem, kuri ir digitālās paaudzes pārstāvji, var būt motivējoša metodoloģijas sastāvdaļa. Darba mērķis ir atklāt, kā sociālā tīkla Facebook uzdevumi var palīdzēt veicināt mājasdarbu izpildi 7. klasē. Izvēlētā pētījuma metode ir atsevišķa gadījuma pētījums Rīgas Valsts 3.ģimnāzijā. Datu vākšanas metodes bija 2 anketas 7. klases skolēniem, skolotājas pieraksti ar mājasdarbu nodošanas laiku un biežumu, atgriezeniskās saites veidlapas un intervija…
