Corporate Sustainability – From a Fuzzy Concept to a Coherent Reality
2018
Abstract During the last few decades, the search for sustainability has experienced a tremendous momentum, encompassing all the levels of the global system. Fuelled by complex (both proactive and reactive) motivators, the process has surpassed the characteristics of an intellectual endeavor – more preoccupied by idealist goals, and less focused on the actual means to achieve them – and has proved that it can successfully be transposed into the corporate real world – of decision making, objective assessment, and relentless scrutiny. The paper aims to (broadly) explore the world of the most sustainable corporations – based on a descriptive (factual and dynamic) analysis of Corporate Knight’s …
Comparing analytical methods to detect SARS-CoV-2 in wastewater
2021
Wastewater based epidemiology (WBE) has emerged as a reliable strategy to assess the coronavirus disease 2019 (COVID-19) pandemic. Recent publications suggest that SARS-CoV-2 detection in wastewater is technically feasible; however, many different protocols are available and most of the methods applied have not been properly validated. To this end, different procedures to concentrate and extract inactivated SARS-CoV-2 and surrogates were initially evaluated. Urban wastewater seeded with gamma-irradiated SARS-CoV-2, porcine epidemic diarrhea virus (PEDV), and mengovirus (MgV) was used to test the concentration efficiency of an aluminum-based adsorption-precipitation method and a polyethylene…
Measurements of organochloro compounds at a metal reclamation plant
1993
Abstract Kuusakoski Ltd is a metal reclamation company operating world wide. Metals recovered are mainly aluminium, copper and different steels. NaCl and KCl are used in processes. Sampling and emission analysis of PCP's, PCB's, PCDD/PCDF's and PAH's were made from seven processes at plant. Emissions indicate, that large part of chlorinated aromatic compounds are formed due to PVC-plastic in cables and car components. On the basis of this study, we suggest, that chlorinated benzenes, -naphtalens and -diphenyl ethers should also be measured in the emissions.
Transfer of hexazinone and glyphosate through undisturbed soil columns in soils under Christmas tree cultivation.
2004
Abstract Field studies monitoring pesticide pollution in the Morvan region (France) have revealed surface water contamination by some herbicides. The purpose of this study was to investigate in greater detail the transport of two herbicides, used in Christmas tree production in the Morvan, under controlled laboratory conditions. Thus, the leaching of hexazinone (3-cyclohexyl-6-dimethyl-amino-1-methyl-1,3,5-triazine-2,4 (1H,3H) dione) and glyphosate ( N -(phosphono-methyl-glycine)) through structured soil columns was studied using one loamy sand and two sandy loams from sites currently under Christmas tree cultivation in the Morvan. The three soils were cultivated sandy brunisol [Sound refer…
Real-time PCR detection of Ochroconis lascauxensis involved in the formation of black stains in the Lascaux Cave, France
2012
A real-time Polymerase Chain Reaction (PCR) assay was developed to detect and quantify Ochroconis lascauxensis in the Lascaux Cave in France. This fungus is the principal causal agent of the black stains threatening the Paleolithic paintings of this UNESCO World Heritage Site. The black stains outbreak could not be stopped in spite of using intensive biocide treatments. A sensitive and time-saving protocol is needed for determining the extent of the colonization. Sets of primers that target the ITS and RPB2 regions were designed and evaluated for specificity against O. lascauxensis. Genomic DNA extracted from five species of Ochroconis and 13 other fungal species frequently isolated from ca…
A revision of the new world species of Polytrichophora Cresson and Facitrichophora, new genus (Diptera, Ephydridae)
2012
The New World species of Polytrichophora Cresson and Fascitrichophora new genus, are revised. Fifteen new species are described (type locality in parenthesis): Fascitrishophora atrella sp. n. (Costa Rica. Guanacaste: Murciélago [10°56.9’N, 85°42.5’W; sandy mud flats around mangrove inlet]), F. carvalhorum sp.n. (Brazil. São Paulo: Praia Puruba [23°21’S, 44°55.6’W; beach]), F. manza sp. n. (Trinidad and Tobago. Trinidad. St. Andrew: Lower Manzanilla (12 km S; 10°24.5’N, 61°01.5’W), bridge over Nariva River), F. panama sp. n. (Panama. Darien: Garachine [8°04’N, 78°22’W]), Polytrichophora adarca sp. n…
The histology of ovarian cancer: worldwide distribution and implications for international survival comparisons (CONCORD-2).
2016
OBJECTIVE: Ovarian cancers comprise several histologically distinct tumour groups with widely different prognosis. We aimed to describe the worldwide distribution of ovarian cancer histology and to understand what role this may play in international variation in survival. METHODS: The CONCORD programme is the largest population-based study of global trends in cancer survival. Data on 681,759 women diagnosed during 1995-2009 with cancer of the ovary, fallopian tube, peritoneum and retroperitonum in 51 countries were included. We categorised ovarian tumours into six histological groups, and explored the worldwide distribution of histology. RESULTS: During 2005-2009, type II epithelial tumours…

Varieties of agencies during working life changes
2020
The aim of this study is to shed light on the varieties of workers´ agencies in working life change situations, which is an under-researched topic in the literature of workplace learning and in working life studies. The research questions are what kinds of agencies there are to be found when workers encounter changes and how the different kinds of agencies are connected together. The understanding of agency is grounded on the subject-centered socio-cultural approach, whereas the methodological approach is based on applying life-course perspective on research material consisting of 48 working life narratives written by Finnish adults. The narratives are analyzed by abductive content analysis…
