Labour Mobility in Construction: European Implications of the Laval un Partneri Dispute with Swedish Labour
2006
The accession to the European Union of new member states from central and eastern Europe, with weak trade union movements, poorly developed social dialogue and inferior working conditions, has been viewed as a threat to regulated labour standards in the EU-15. This article examines a high-profile labour dispute arising from the conditions of Latvian construction contract labour in Sweden. The dispute exposes weaknesses in the protective floor of minimum standards offered by the posted workers Directive. It also goes to the core of the debate about the preservation of a ‘European social model’ and the proposed Services Directive.
Is Education Getting Lost in University Mergers?
2010
Mergers are common phenomena in higher education institutions. Improving educational quality is typically one of the stated goals of university mergers. Yet, little information exists about how merging institutions approach this goal. This paper presents results from a study of planning documents created prior to four mergers in the Finnish higher education system. These documents show that there was little concrete attention given to the educational issues related to the mergers. Most attention was placed on administrative issues and issues related to research. When educational issues were mentioned, it was almost always in the form of vague goals with few details provided about how the go…
Interlingual translation of the International Financial Reporting Standards as institutional work
2017
The International Financial Reporting Standards (IFRS) have been widely adopted well beyond English-speaking jurisdictions. Using the Finnish translation of the IFRS as a primary object of investigation, this article analyses the way in which the standards are translated into another language. Drawing on interviews with translators and translation review committee members and on an analysis of archival materials, it provides an empirically grounded understanding of practical problems of linguistic equivalence, and the institutional work required to maintain the IFRS as a global, translingual institution. Accordingly, the article highlights the constructed and negotiated nature of the lingui…
Imaging standardisation in metastatic colorectal cancer: a joint EORTC-ESOI-ESGAR expert consensus recommendation
2022
Background: Treatment monitoring in metastatic colorectal cancer (mCRC) relies on imaging to evaluate the tumor burden. Response Evaluation Criteria in Solid Tumors (RECIST) provide a framework on reporting and interpretation of imaging findings yet offer no guidance on a standardized imaging protocol tailored to mCRC patients. Imaging protocol heterogeneity remains a challenge for the reproducibility of conventional imaging endpoints and is an obstacle for research on novel imaging endpoints. Patients and methods: Acknowledging the recently highlighted potential of radiomics and artificial intelligence (AI) tools as decision support for patient care in mCRC, a multidisciplinary, internatio…
Ceftazidime Determination in Serum by High-pressure Liquid Chromatography
2004
A rapid and sensitive high-pressure liquid chromatographic method with simple sample preparation was developed for the quantitative analysis of the beta-lactam antibiotic ceftazidime (CAS 78439-06-2, Fortum). A good linear relationship was established between the peak area and the amount of ceftazidime injected over a concentration range of 1 to 200 microg/ml. The detection limit of the method was calculated to be 0.9 microg/ml. Stability was shown at 4 degrees C and at -196 degrees C for time periods of 2 h and 84 days, respectively.
Sensitive screening of synthetic cannabinoids using liquid chromatography quadrupole time-of-flight mass spectrometry after solid phase extraction.
2021
Analysis of synthetic cannabinoids still poses a challenge for many institutions due to the number of available substances and the constantly changing drug market. Both new and well-known substances keep appearing and disappearing on the market, making it hard to adapt analytical methods in a timely manner. In this study, we developed a qualitative screening approach for synthetic cannabinoids and their metabolites by means of liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). Samples were measured in data-dependent auto-MS/MS mode and identified by fragment spectra, retention time and accurate mass. Two established solid phase extractions were compared using fo…

Resumen Introduccion La normalizacion del proceso de intercambio terapeutico de medicamentos en el medio hospitalario, mediante el establecimiento y difusion de criterios normalizados, se ha definido como una actividad que conduce a un incremento en la calidad asistencial y, consecuentemente, a una mejora en el cuidado del paciente. Objetivo Establecer un intercambio terapeutico normalizado para los antagonistas del receptor de angiotensina-II (ARA-II) en el tratamiento de la hipertension arterial y, evaluar la idoneidad de los intercambios terapeuticos realizados en un sistema integral de dispensacion individualizada de medicamentos. Material y metodos El intercambio terapeutico normalizad…
Determination of fatty alcohol ethoxylates by derivatisation with maleic anhydride followed by liquid chromatography with UV-vis detection.
2007
The esterification of fatty alcohol ethoxylates (FAEs) by melting with maleic anhydride has been studied in the presence of urea. The reaction rate and yield of non-ethoxylated and ethoxylated alcohols increase largely when grinded urea is suspended in the reaction medium, a 100% yield being achieved at 80 degrees C in 15 min. The procedure is tolerant to the presence of large amounts of water. The UV-vis response factors of the derivatives of individual FAE oligomers vary little with the number of carbon atoms in the alkyl chain, n, and the number of ethylene oxide units, m. Derivatised samples of industrial FAE mixtures, cleaning products and river and sea waters were chromatographed on a…
Monte Carlo calculation of dose rate distributions around 192Ir wires.
1997
Monte Carlo calculations of absolute dose rate in liquid water are presented in the form of away-along tables for 1 and 5 cm 192 Ir wires of 0.3 mm diameter. Simulated absolute dose rate values can be used as benchmark data to verify the calculation results of treatment planning systems or directly as input data for treatment planning. Best fit value of attenuation coefficient suitable for use in Sievert-integrals-type calculations has been derived based on Monte Carlo calculation results. For the treatment planning systems that are based on TG43 formalism we have also calculated the required dosimetry parameters.
Understanding 802.11e contention-based prioritization mechanisms and their coexistence with legacy 802.11 stations
2005
The IEEE 802.11e task group has reached a stable consensus on two basic contention-based priority mechanisms to promote for standardization: usage of different arbitration interframe spaces and usage of different minimum/maximum contention windows. The goal of this article is to provide a thorough understanding of the principles behind their operation. To this purpose, rather than limit our investigation to high-level (e.g. throughput and delay) performance figures, we take a closer look at their detailed operation, also in terms of low-level performance metrics (e.g., the probability of accessing specific channel slots). Our investigation on one hand confirms that AIFS differentiation prov…
