Characterization of microscopic disorder in reconstructed porous materials and assessment of mass transport-relevant structural descriptors
2016
The targeted optimization of the functional properties of porous materials includes the understanding of their transport properties and thus requires knowledge about the relationship between material synthesis, resulting in three-dimensional material morphology, and relevant transport properties. In this Perspective, we present our views and results on the characterization of microscopic disorder in functional porous materials, which are widely used today as fixed beds in adsorption, separation, and catalysis. This allows us to identify structural parameters that impact their mass transport properties and eventually their overall performance in technological operations. We address this comp…
Influence of temperature on mass transfer in an incomplete trapping single hollow fibre supported liquid membrane extraction of triazole fungicides.
2008
The influence of temperature in a single hollow fibre supported liquid membrane extraction of triazole fungicides with a stagnant acceptor phase was investigated. The mass transfer parameters such as diffusion coefficient, flux and apparent viscosity were determined at temperature ranging from 278 K to 313 K. Increase in temperature led to an increase in diffusion coefficient and flux. The apparent viscosity also decreased with an increase in temperature. The degree of trapping in the acceptor phase influenced the mass transfer at higher temperature. At lower temperature, the transport of analytes from the donor solution through the donor-membrane interface and through the membrane mainly a…

Metamorfosis de la prensa de referencia en el contexto digital: clickbait y estrategias de tabloide en Elpais.com
2016
En un contexto marcado por la incertidumbre tecnológica y la búsqueda de un modelo de negocio viable, los medios digitales han sucumbido a diversas estrategias para captar audiencia, reflejada en los clicks que genera cada titular. Este artículo centra la atención en un medio de referencia como El País para analizar qué opciones ha incorporado para atraer visitas a la web. A partir de una metodología cuantitativa y cualitativa, se estudian los contenidos de cuatro secciones que ha sumado Elpais.com en los últimos dos años (SModa, Icon, BuenaVida y Verne), que han logrado generar –en especial la última– un tráfico importante. Las conclusiones del análisis muestran una apuesta por la tabloidi…
Pressure-Induced Deformation of Pillar-Type Profiled Membranes and Its Effects on Flow and Mass Transfer
2019
In electro-membrane processes, a pressure difference may arise between solutions flowing in alternate channels. This transmembrane pressure (TMP) causes a deformation of the membranes and of the fluid compartments. This, in turn, affects pressure losses and mass transfer rates with respect to undeformed conditions and may result in uneven flow rate and mass flux distributions. These phenomena were analyzed here for round pillar-type profiled membranes by integrated mechanical and fluid dynamics simulations. The analysis involved three steps: (1) A conservatively large value of TMP was imposed, and mechanical simulations were performed to identify the geometry with the minimum pillar density…
Reporting in Conflict Zones in Pakistan: Risks and Challenges for Fixers
2020
As a backbone of reporting in war and conflicts, fixers offer essential assistance to the foreign correspondent in conflict zones, also in Pakistan. With valuable local knowledge and contacts, fixers can arrange travel to secure entry of foreign correspondents into conflict zones in addition to securing interviews with otherwise unattainable figures, while offering reliable translation services. Pakistani media, despite being one of the largest and most developed in South Asia, remains under the strict control of powerful military establishment and government, while seeming to mirror the overarching government sentiment with a distinct lack of research-based news. Challenging this state of …
A Relational Approach to How Media Engage With Their Audiences in Social Media
2022
People are increasingly turning to social media for their news and for sharing and discussing news with others. Simultaneously, media organizations are becoming platform-dependent and posting short forms of their news on their social media sites in the hope that audiences will not only consume this news but also comment on and share it. This article joins other media and journalism studies exploring this phenomenon through a relational approach to media audiences to better understand how media organizations, particularly newspapers, are cultivating relationships with audiences via social media. Drawing on public relations theory about organization–public relationships, the article examines …
Study on the Reputation of the (MASS) Media in Romania
2021
Abstract Part of a bigger research project conducted by Media Reputation Lab (Media REP Lab) on the reputation of media in Europe, the study explores the reputation of media among informed population in Romania. A sample of 100 cases was involved in the online survey taking place in December 2019. The results provide a description of the country’s media reputation (media in general: radio, print, digital and television). For each one of these media, the valuation obtained by each of the reputational attributes (credibility, rigor, impartiality, willingness to rectify) by the informed population would be indicated. Moreover, insights on the knowledge and use, as well as on the reputation (ov…
Problemy wczesnej eduacji medialnej
2017
Media pośredniczą w poznawaniu świata i komunikowaniu się ze światem. Korzystanie przez dziecko ze środków masowego przekazu ma wiele walorów, pod warunkiem że zostanie ono do tego odpowiednio przygotowane i ukierunkowane. W procesie wczesnej edukacji medialnej znaczącą rolę odgrywają kompetencje nauczycieli w zakresie korzystania z mediów i przygotowania do ich odbioru.
A Virtue Ethical Exploration of Multi-Attractedness
2018
Tässä artikkelissa tarkastelen moniviehättyneisyyden käsitettä hyve-etiikan kontekstissa. Moniviehättyneisyys on luonteenpiirteen tapainen ominaisuus, jonka kantaja tulee päätöksiä tehdessään ristiriitaisten näkökulmien puoleensa vetämäksi. Tavoitteeni on syventää moniviehättyneisyyttä koskevaa ymmärrystä selvittämällä, miten se voidaan Aristoteelisen hyve-etiikan piirissä määritellä. Tarkastelun lähtökohtana on Lehtosen näkemys siitä, että moniviehättyneisyys saattaa olla hyödyksi päätöksenteolle. Tutkimuksen aineiston muodostaa moniviehättyneisyyden teoria, joka muodostuu useista erillisistä teoreettisista kirjoituksista. Filosofisen tarkastelun viitekehys muodostuu Nikomakhoksen etiikan …
