Sorption properties of lignite for some acid dyes
2014
Przedstawiono właściwości sorpcyjne węgla brunatnego pochodzącego z KWB Bełchatów w stosunku do wybranych barwników kwasowych (Acid Red 18, Acid Black 1, Acid Blue 9 oraz Acid Green 16) w roztworach wodnych. Wyznaczona w statycznych warunkach kontaktu faza stała-roztwór maksymalna pojemność sorpcyjna węgla w stosunku do wybranych barwników kwasowych mieściła się w zakresie 3,80-22,7 g/kg i rosła w szeregu AR-182). W wiązaniu barwników AR-18, AB-9 i ABk-1 odgrywała rolę adsorpcja jonowymienna (E>8 kJ/mol), przy czym jej udział w wiązaniu barwników był największy dla AR-18.
Towards a more dynamic stakeholder model : Acknowledgning multiple issue arenas
2010
Purpose – The paper suggest that corporate communications is becoming less predictable as interaction with stakeholders is moving from organizational control toward ‘issue arenas’, places of interaction where an issue is discussed by stakeholders and organizations both online and within the traditional media. The role of corporate communications and public relations is broadening beyond the traditional relationship management to issue arena monitoring. Design/methodology/approach – Theoretical approach with six axioms suggested. Findings – Several central theories of corporate communications are combined with issues management and stakeholder theory to argue for a multiplicity of new ‘issue…
Keskisuomalainen turveprotesti : Pelastetaan reittivedet -yhdistyksen tarina
2020
Ympäristökonfliktien hallinnassa käydään kauppaa taloudellisten hyötyjen ja ympäristöhaittojen välillä. Nykyinen hallinnan malli on edustuksellis-korporatiivinen. Turvetuotantoa, jolla paikallinen väestö näkee olevan vesiympäristöä pilaavia vaikutuksia, ohjataan ja päätösten valmistelua tehdään ryhmässä, johon osallistuu ministeriöiden alaisia viranhaltijoita sekä turvealan yritysten ja etupiirien toimijoita. Vain Suomen luonnonsuojeluliitto on edustanut kansalaisjärjestöjä. Luonnon pilaantumisesta kärsivät kansalaiset pidetään hallintajärjestelmän ulkopuolella varsinkin silloin, kun kansalaisten vaatimukset ovat ristiriidassa luontoa hyödyntävän tuotannollisen toiminnan kanssa. Tällaiseen …

2017
The monograph by Edward Nycz, entitled Druga szansa młodzieży. Studium funkcjonowania Ochotniczych Hufców Pracy [A second chance for youth. A study in the functioning of the Voluntary Labour Corps], orders in a chronological way the knowledge on the activity of the organization of the Voluntary Labour Corps (VLC) in Poland. The author - taking advantage of the rich literaturę in the fields of pedagogy and sociology and discussing the results of his own studies - offers valuable information with reference to the share of the VLC in the work with the young who remain on the social margin and are socially maladjusted.
Triggering sustainability communication in a B2B context: combining action research and sensemaking
2021
PurposeThe paper explores processes associated with the adoption of corporate sustainability communication in a B2B context. It employs a combined action research and sensemaking approach to document moments that precede the initiation of external sustainability communication.Design/methodology/approachThe paper is the outcome of an action research project, where we examine the case of one industrial company that was silent on its multiple sustainability-related practices, but recently decided to become more transparent to the outside world. A processual approach to sensemaking is adopted to show how organisational and non-organisational members actively participated in meaning co-construct…
The use of social media for knowledge acquisition and dissemination in B2B companies: an empirical study of Finnish technology industries
2019
Scholars and practitioners of knowledge management have paid increasing attention to the adoption of social media in business-to-business (B2B) setting for knowledge sharing; however, both the theoretical and empirical research in this domain are quite fragmented. The aim of this research is to deepen the understanding about the B2B companies’ awareness of the potentials of social media in improving their absorptive capacity and, consequently, if and how such companies deploy knowledge strategies based on social media adoption. We carried out an empirical survey of Finnish technology companies operating purely in B2B markets. Results highlight that social media adoption is still in a prelim…
Cadmium Metal–Organic Frameworks Based on Ditopic Triazamacrocyclic Linkers: Unusual Structural Features and Selective CO 2 Capture
2017
International audience; Two three-dimensional cadmium metal organic frameworks with general formula [Cd-2(L-1)(H2O)(3)](NO3)(0.7)(HCOO)(0.2)Br-0.1 (Cd2L1, L-1 = 1,4,7-tris(4-carboxybenzy1)-1,4,7-triazacyclononane) and Cd(HL2)(H2O)(2) (CdL2, L-2 = 1,4,7-tris(3-(4-benzoate)prop-2-yn-1-yl)-1,4,7-triazacydononane) based on 1,4,7-triazacyclononane N-functionalized by different arylcarboxylic acids were prepared under solvothermal conditions and characterized by single crystal X-ray analysis and porosity measurements. The crystal structure of Cd2L1 reveals a cationic net with a bcs topology,. and nodes are constituted by dinuclear cadmium complexes, in which each cadmium atom adopts a hexacoordin…

Zanieczyszczenie metalami ciężkimi Matricaria chamomilla L. i Plantago lanceolata L
2019
Celem badań była ocena zanieczyszczenia metalami ciężkimi (Mn, Fe, Ni, Cu, Zn, Cd i Pb) rumianku lekarskiego (Matricaria chamomilla L.) i babki lancetowatej (Plantago lanceolata L.). W ramach biomonitoringu pasywnego pobrano próbki roślin leczniczych oraz próbki gleby, na której rosły rośliny. Metale ciężkie oznaczono za pomocą absorpcyjnej spektrometrii atomowej (AAS). Na podstawie przeprowadzonych badań można stwierdzić, że zioła wykorzystane do badań różniły się pod względem stężeń metali ciężkich w zależności od miejsca ich pobierania. Wszystkie próbki ziół były zanieczyszczone wysokimi stężeniami manganu, żelaza oraz cynku. Badane próbki gleb z grupy B i C według rozporządzenia ministr…
