Sorbenty i membrany polimerowe w przygotowywaniu do analizy próbek środowiskowych i biologicznych
2005
Istotny element procedur analitycznych dotyczących skomplikowanych mieszanin jakimi są próbki środowiskowe bądź biologiczne stanowi wstępne wyodrębnienie, oczyszczenie i zatężenie analizowanej substancji. Do tego celu coraz częściej stosuje się sorbenty polimerowe i układy membranowe. W niniejszym przeglądzie przedstawiono najważniejsze i najczęściej używane metody przygotowania próbek środowiskowych do analizy, czyli ekstrakcję do fazy stałej (SPE) i unieruchomione membrany ciekłe (SLM). Szczególną uwagę zwrócono na możliwość wykorzystania w SPE sorbentów o zróżnicowanej polarności. Omówiono możliwości wykorzystania ekstrakcji z zastosowaniem SLM, w tym ekstrakcji przy użyciu selektywnych …

Pathways for the amplification of agroecology in African sustainable urban agriculture
2020
A growing awareness that highly intensified agricultural systems have made a substantial worldwide contribution to the worsening of the resilience capacity of natural ecosystems has, over the last twenty years, brought general attention to agroecological management models. This aspect is even more evident in industrial agriculture, which is based on the use of multiple chemical products derived from non-natural synthesis. In more developed countries, a new idea of ecology linked to agricultural production has been increasingly developed and, for this reason, there has been a greater diffusion of differentiated agricultural models taking into consideration the environmental impact of product…

User-Centered Development of Video Telephony for Servicing Mainly Older Users: Review and Evaluation of an Approach Applied for 10 Years
2006
A research and development (R&D) approach has been applied to video telephony (VT) in northern Finland since 1994 by broad consortia. The focus has been on the considerable involvement of ergonomics within the engineering and implementation of VT. This multidisciplinary participatory ergonomic R&D approach (PERDA) is described briefly, in general and through two cases. The user-centeredness should be discernible in this sociotechnical systemic entity. A consortium—comprising mainly manufacturers, individual and organizational users of technological products, and R&D organizations—serves as a natural context for product development. VT has been considered to have much potential for enhancing…

Do Online Travel Communities Matter? A Literature Review
2017
The emergence of social media has migrated consumers from peripheral stakeholders to strategic partners whose inputs are critical for successful product and service innovation. Online communities provide a platform for aggregation of consumers from diverse backgrounds; online travel communities (OTCs) have recently attracted growing interest in the information systems and tourism literature because their unofficial boundary spanning role influences consumer interest in destinations. Importantly, this literature remains largely fragmented because of conflicting findings. The present study seeks to integrate prior OTC research in order to understand the motivations and consequences (negative …
