The application of electroanalytical methods to determine affinity series of metal cations for functional biosorbent groups

2018

Abstract The affinity of the selected heavy metal cations: Mn 2 + , Ni 2 + , Cu 2 + , Zn 2 + , Cd 2 + , Pb 2 + and Na + , K + , Mg 2 + , Ca 2 + was determined for the functional groups located on the surface of leached barley middlings, so called Brewer's spent grain (BSG) – a by-product of the brewing industry. A simple method for determining the affinity series, with the use of a conductivity meter and a pH-meter, was described. It was demonstrated that the affinity of cations for the functional groups located on the surface of the BSG increases in the series: Na + + 2 + 2 +  ≈ Zn 2 + 2 +  ≈ Ca 2 + 2 + 2 + 2 + , and the series was determined by comparing concentrations expressed in gram e…

Economic globalisation, the perceived room to manoeuvre of national governments, and electoral participation: Evidence from the 2001 British General …

2016

Recent macro-level research argues that economic globalisation negatively affects electoral turnout by constraining the leeway of national governments and thereby rendering elections less meaningful to voters. This article analyses the link between perceptions of the national government's room to manoeuvre and turnout on the individual level. Drawing on the 2001 British General Election, it is shown that citizens who believe that economic globalisation leaves the national government with less influence on the economy are less likely to report to have voted. Further findings also support the proposed theoretical model according to which room to manoeuvre perceptions affect turnout via views …

Political interest furthers partisanship in England, Scotland, and Wales

2016

ABSTRACTAccording to much of the literature, partisanship in Britain exercises little independent influence on the vote but merely reflects voters’ prospective and retrospective evaluations of the parties’ performance with regard to their management of the economy, national security, and public services. In this view, partisanship comes close to Fiorina’s model of a “running tally” of political experiences. Similarly, Dalton’s notion of “cognitive mobilization” suggests that seeking out political information should undermine both the need for and the likelihood of party identification. Applying Mixed Markov Latent Class Analysis to the British Election Study Panel 1997–2000, we challenge th…

Experimental study of a naturally weathered stiff clay

2016

Studying the shear strength of a naturally weathered clay is important to understand rain-induced slope failures in weathered soils. However, experimental studies on naturally weathered soils are limited. The paper focuses on the laboratory experimental investigation carried out to analyse the shear strength of a naturally weathered stiff clay that can be found in unsaturated conditions in situ. This has an important practical relevance in the evaluation of the stability conditions of natural slopes at clay outcrops. Different experimental techniques of suction measurement were used to obtain the soil-water retention curve of the clay over a wide range of suctions. Scanning electronic micr…

Sobre las posibilidades de reforma del modelo de empleo público español: límites constitucionales y jurídicos al modelo actual y sus sistemas de acce…

2021

En este trabajo se expone la conveniencia de revisar algunas de las pautas tradicionales con las que se ha declinado en nuestro país el régimen jurídico del empleo público y, en particular, de los modos de acceso. A la luz de algunos de los problemas de tipo práctico que la experiencia acumulada muestra que presenta el actual sistema español, e inspirados en la experiencia comparada se proponen diversas soluciones concretas que, a nuestro juicio, serían perfectamente compatibles con los principios constitucionales en la materia y ayudarían a mejorar el modelo de empleo público en general y, específicamente, los sistemas de acceso a este en condiciones de igualdad: limitar la reserva a perso…

Selection of time windows in the horizontal-to-vertical noise spectral ratio by means of cluster analysis

2016

The selection of the elementary analysis windows in continuous noise recordings for optimal estimation of the mean horizontal‐to‐vertical spectral ratio (HVSR) curve is generally performed by visual inspection of HVSR curves considered as functions of time. Starting from full‐length records, HVSR curves are determined in consecutive time windows of appropriate lengths. Time windows with HVSR curves that are anomalous on the basis of a simple visual inspection are generally ignored in the computation of the average HVSR curve. It is often very difficult to optimize the selection of time windows to be used for the calculation of the HVSR curve representative of a site. The use of nonobjective…

Event Management and Terrorism in a Global Order

2020

Over the recent years, the public spectacle and media events have become fertile grounds for terrorist attacks. Particularly, media events play a leading role enhancing the social cohesion as well as revitalizing the psychological frustrations that happened during the working days. Paradoxically, terrorism needs to maximize its gains while the costs are minimized. The spectacularisation tourism and events offer a double-edge sword. The same attractiveness that makes global cities a safer place to live are employed by the terrorist cells to cause chaos and uncertainty. The chapter theoretically explores the difficult interrelation between terrorism and event management as well as the concept…

Evaluation of Glyphosate Ecotoxicity and Biodegradability in the Municipal Wastewaters

2018

Glyphosate (G) is a broad-spectrum systemic organophosphate herbicide being widely used to control weeds in agricultural fields and urban areas. Its safety for both human health and aquatic biomes is a subject of wide debate. This study was aimed at evaluating the removal efficiency and ecotoxicity of G based herbicide (GBH) Klinik® (Nufarm, Austria) added to the raw municipal wastewater (WW) in a lab-scale model column system. The effect of oxide ceramics as a filtering medium (treatment „B”), as well as activated sludge and nutrients (treatment „C”) was compared with the control columns, which contained only WW (treatment „A”). After 72h treatment of WW spiked with 100 mg/L G, the lowest …
