Electroplating wastes
Authors: Reis M. Teresa A. , Ismael M. Rosinda C. 
Published: April 2018

AbstractElectroplating and other metal finishing industries, like every metal and metallurgical industry, are associated with the generation of waste. Spent electroplating baths, waste pickle liquors, etching solutions and rinse waters from electroplating units and steel finishing operations are complex solutions containing acids and several hazardous metals. It is compulsory, for environmental and economic reasons, to treat these solutions for recovering acid, metals and/or reusing these solutions/waters. This article is a review on the characterization of the wastes that are generated in electroplating industry, steel processing and copper etching in printed circuit boards manufacture, as well as on the treatment and regeneration methods of such streams. Various techniques, such as neutralization, crystallization, evaporation, pyrohydrolysis, electrodialysis, ion exchange, classical solvent extraction and membrane-based solvent extraction are presented, their advantages and disadvantages being scrutinized.
Dosimetric characterization of novel polycarbonate/porphyrin film dosimeters for high dose dosimetry: study on complexation effect

Published: April 2018

Abstract
Two novel radiochromic films with 20 μm thickness were made from casting of solutions of polycarbonate (PC) containing 0.5 wt.% tetra phenyl porphyrin (TPPH2) and 5,10,15,20-tetraphenyl-21H,23H-porphine iron(III) chloride (Fe-TPP). Dosimetric characterization of the films as routine dosimeters were studied by spectrophotometric method. On subjecting TPPH2/PC and Fe-TPP/PC film dosimeters to gamma radiation, radiolytic bleaching of films was observed. The effects of metal-complexation on the radiation response of the film dosimeters were studied under 60Co γ-rays exposure in dose range of 0–100 kGy. The results were also compared with the PC/TPPF20 (PC/tetrakis (pentafluorophenyl) porphyrin) dosimeter to evaluate the substituent effect (role of fluorine groups). Experimental parameters including humidity, temperature and pre-irradiation (shelf-life) and post-irradiation storage in dark and in indirect sunlight were examined. The maximum absorbance of Soret band of dyes had meaningful shifts and reduction which arose from complexation and substituents. The dyed films characteristics were found to be stable enough in media with high degrees of temperature and humidity. The results indicate that the radiation-induced decoloration of TPPH2/PC and Fe-TPP/PC films can be reliably tuned and used in high dose dosimetry.
Effect of water chemistry on Eu(III) biosorption by magnetic bioadsorbent
Authors: Li Fengbo , Li Xiaoyu , Cui Pu 
Published: April 2018

Abstract
In this study, magnetic biosorbent was fabricated by chemical co-precipitation of Fe(II) and Fe(III) on the surface Paeclomyces catenlannulatus (P. catenlannulatus) by adding NaOH solution under N2 conditions. The influence of water chemistries (i. e. pH, reaction time, temperature, concentration and ionic strength) on Eu(III) biosorption towards magnetic biosorbent was elucidated by batch technique. The batch experiment showed that Eu(III) biosorption on magnetic biosorbent was independent of ionic strength, suggesting that inner-sphere-surface-complexation predominated Eu(III) biosorption. The biosorption kinetics showed the sorption equilibrium was achieved at reaction time of 24 h, and the maximum biosorption capacity of Eu(III) on magnetic biosorbent calculated by Langmuir model was 69.45 mg/g at pH 3.5 and 298 K. The regeneration experiments showed the slight decrease of biosorption capacity after the fifth recycles. These results suggested that this magnetic biosorbent presented the fast biosorption rate and high biosorption capacity for Eu(III). The results of XPS analysis revealed that various oxygenated function groups (e.g. carboxyl, hydroxyl groups) were responsible for the high effective biosorption of Eu(III). These findings manifested that this magnetic biosorbent could be as a high-effective material for the immobilization and pre-concentration of radionuclides from aqueous solution in environment remediation.

Published: April 2018

AbstractMedia and digital literacy are being increasingly recognized as a fundamental competence for teachers of 21st century, but teachers’ professional development is still far from coping with this emerging need. This paper aims at providing some recommendations for integrating media literacy into in-service teacher training programs. To this purpose, it will present the results of the experimentation carried out in three European training institutions within the framework of the European project e-MEL (e-Media Education Lab, 2014–17). The overall training process was monitored and evaluated ex-ante, ongoing and ex-post. This paper illustrates and discusses the main findings of the experimentation focusing on strengths and challenges for implementing a teacher training program on digital and media literacy. It concludes with some recommendations and more general reflections on future research directions.

Abstract
Solid-phase microextraction (SPME) is a sample preparation technique with many applications that is being continuously developed. In this technique, the type of fiber coating plays a crucial role for extraction efficiency. Currently available commercial coatings have certain drawbacks that have been overcome by the development of new coatings based on novel materials; these have improved the efficiency of extraction, selectivity and stability of commercial coatings. Pharmaceutical and personal care products (PPCPs) are one of the most important groups of emerging contaminants; however, some studies suggest that these compounds can cause adverse health effects. No official monitoring protocols for these compounds are currently available, so the establishment of analytical methods that allow their determination in environmental samples is required. The complexity of environmental samples together with the low concentration levels of these compounds makes necessary the use of sample preparation techniques capable of removing interferences, as well as preconcentrated analytes, and SPME is a very promising alternative to achieve this. This review describes the recent developments in SPME with classical and novel coatings and its applications for PPCP determination in environmental samples.
Planned stagnation? The economic plan vs. reality in the Czechoslovak railway sector of the 1970s and 1980s
Authors: Nigrin Tomáš 
Published: April 2018

Abstract
The article deals with the state of the railway sector in a centrally planned economy in Czechoslovakia in the 1970s and 1980s. It compares the “to-be” position of the Czechoslovak state railway with the real situation in the railway sector. The Czechoslovak railway sector changed a lot during the two analysed decades – it lost its superior position to road transport and showed evident signs of stagnation, even though a big part of economy was dependent on the railway transport. The position of railway transportation had weakened within the two decades and the country lost its stage by stage initiative in modernisation of the railway sector. The railway sector lost its pre-1970s sovereignty in transport and had become more dependent on the general situation of the Czechoslovak economy. It was the reason for stagnation as a result of development of the railway sector in late socialism in Czechoslovakia.
Long-run and Short-run Monetary Policy Transmission Channels in Lebanon
Authors: Awdeh Ali 
Published: April 2018

Abstract
This research detects the existence of monetary policy transmission mechanisms in Lebanon through which the actions of the central bank propagate. By adopting co-integration analysis and VECM frameworks, and by exploiting monthly data between January 1994 and December 2016, the research revealed the existence of a long-run interest rate channel, affecting both resident private sector deposits and credit to the private sector. Another short-run capital channel was revealed, affecting total credit provided by the banking sector. Additionally, the empirical results show that (1) deposit inflows are not attracted by high interest rates, but stimulated by confidence provided by large foreign currency reserves held by the central banks; (2) non-residents deposit inflows could represent a substitute for local credit; (3) banks pass-through any increase in funding cost to borrowers; and (4) an increase in external interest rates may trigger deposit outflows.
Groupuscular identity-creation in online-communication of the Estonian extreme right
Authors: Madisson Mari-Liis , Ventsel Andreas 
Published: April 2018

AbstractFor explaining the dispersed extreme right movements that are presently flourishing in the online sphere, British historian and political theorist Roger Griffin has elaborated the concept ofgroupuscular right. The groupuscular right can be characterized by the non-hierarchic and the rhizomatic structure of intra-groupuscular communication. Our study on Estonian groupuscular right complements it with the ideas of cultural semiotics that help to explicate self-descriptions of particular groupuscular nodes (e.g., blog posts) but also to analyze their relations with other extreme right groupuscules and with the radical online sphere as a whole. Although the extreme right’s communication has become more heterogeneous in its form and content, it is still possible to distinguish central and peripheral meanings. Our approach allows us to understand a seemingly paradoxical problem: why, despite of the plurality of different view-points available on the web, are groupuscular communications still dominated by strict and homogeneous ways of modeling information.
Histopathology of Hepatic Sinusoidal Obstruction Syndrome After Neoadjuvant Oxaliplatin-Based Chemotherapy
Authors: Micev Marjan , Basaric Dragan , Micev Milena Cosic , Galun Danijel 
Published: April 2018

Abstract
Sinusoidal obstruction syndrome („blue liver syndrome“) has been frequently associated with oxaliplatin-based neoadjuvant chemotherapy in patients with colorectal liver metastasis. Hepatotoxic vascular lesions in the nontumourous liver parenchyma result in hypoperfusion and tissue hypoxia leading to lower tumour response to oncologic treatment and to increase the risk of liver metastasectomies. Furthermore, hepatic parenchyma injuries could be aggravated by hepatic resection itself. Contrary to standard surgical techniques, radiofrequency assisted liver resection significantly reduce harmful intraoperative blood loss and perfusion-reperfusion effects. We compared histological alterations in 59 specimens of bloodless radiofrequency-assisted liver recetions made for colorectal metastases to those in 38 specimens of standard liver resections. In general, the main histologic alterations in both examined groups related to oxaliplatin include SOS lesions (69.35%), fibrosis (50.95%) and steatosis (38%). After scoring of histopathological parameters based on modified criteria according to Rubbia-Brandt et al., they were statistically insignificant between both groups for portal and/or porto-portal fibrosis (59.3% vs 47.4%, respectively) and moderate/severe macrovacuolar steatosis (10.2% vs 26.3%). Similar distribution between groups was shown for surgical hepatitis with „borderline“ statistical significance (23,7% vs 42,1%, p= 0.05). However, there were significant differencies in vascular lesions, particularly for hemorrhagic centrilobular necrosis (10,2% vs 31,5%, p= 0.01) and peliosis (15,2% vs 36,8%, p= 0.04), but were not significant for sinusoidal dilatation and congestion as well as surgical necrosis. Highgrade vascular lesions such as hemorrhagic centrilobular necrosis and peliosis are less frequent in cases of radiofrequency-assisted liver recetions and might be associated with better clinical outcome in these patients.
Comprehension of Spatial Metaphors After Right Hemisphere Stroke: A Case Report
Authors: Kljajevic Vanja , Vranes-Grujicic Milenka , Raskovic Katica 
Published: April 2018

Abstract
Studying how spatial information interacts with figurative language processing in right-hemisphere (RH) stroke patients is a relatively neglected area of research. The goal of the present case study was to establish whether an ischemic lesion in the right temporo-parietal region causing spatial neglect would affect comprehension of sentence-level spatial metaphors, since some evidence indicates the crucial role of the RH in metaphor processing. The patient under study showed some degree of cognitive impairment (e.g., in spatial and verbal working memory, executive control, visuo-spatial matching skills). However, his comprehension of spatial metaphors was preserved. This case illustrates that RH damage does not necessarily affect comprehension of sentence-level spatial metaphors.
The influence of pre- and perioperative administration of gabapentin on pain 3–4 years after total knee arthroplasty

Published: April 2018

Abstract

Background and aims:
Approximately 20% of patients having total knee arthroplasty (TKA) will experience chronic postoperative pain. Recently, preoperative pain facilitation has been associated with chronic pain after TKA, and gabapentin has been shown to decrease pain facilitation. The current study is a secondary follow-up of a primary RCT investigating the effect of gabapentin on acute postoperative pain after TKA and exploring the effect of pre- and perioperative administration of gabapentin on chronic postoperative pain and psychological state 3–4 years after TKA.

Methods:
Patients scheduled for TKA were randomized to either gabapentin 1,300 mg/day, gabapentin 900 mg/day, or placebo daily from 2-h before and 6 days after operation. Pre- and 3–4 years postoperatively pain scores related to pain while walking, at rest, when flexing the hip or the knee were collected. At the same time, the pain catastrophizing scale (PCS) and hospital anxiety and depression scale subscales for anxiety (HADS-A) and depression (HADS-D) were collected.

Results:
Lower postoperative pain while walking, flexing the hip, and at rest were found compared with preoperative scores (p<0.03), but these were not associated with gabapentin treatment (p>0.19). Significantly lower postoperative PCS and HADS-A scores were seen compared with preoperative scores (p<0.001), but these were not associated with gabapentin treatment (p>0.55).

Conclusions:
The current study found that pre- and perioperative administrations of gabapentin do not influence the pain or psychological state 3–4 years after TKA.

Implications:
The current study does not support that short-term pre- and perioperative use of gabapentin can reduce the development of chronic postoperative pain after TKA.
Constitutional Justice in Credit Crises. The Hungarian Case
Authors: Gárdos-Orosz Fruzsina 
Published: April 2018

Abstract
The economic crisis of 2008 brought about a rapid depreciation in the exchange rate of the Hungarian forint (HUF). Debtors in Hungary had borrowed money in foreign currencies—especially the Swiss franc—and now found themselves in a significantly deteriorating situation. The consequences of increased indebtedness reached all levels of society. On various grounds, consumers took out numerous civil law proceedings to challenge consumer loan agreements. Questions raised by these lawsuits were, several times, brought to Hungary’s Supreme Court, and were then taken to the legislature. The legislative acts and judicial decisions that ensued were subsequently reviewed by the Constitutional Court of Hungary. This article analyses the case law the Constitutional Court applied in this crisis situation, and brings out the lack of balancing capacity in the constitutional adjudication. Referring to the principles of basic Rule of Law, the author makes a critical assessment of the new constitutional ideas, measures and legal solutions that emerged.
Risk Analysis of Propulsion System based on Similarity Measure and Weighted Fuzzy Risk Priority Number in FMEA
Authors: Zhou Hang , Yang Yuan-Jian , Huang Hong-Zhong , Li Yan-Feng , Mi Jinhua 
Published: April 2018

Abstract
Due to the epistemic uncertainty, it is difficult for the experts to give precise parameter values in Risk Priority Number (RPN) evaluations. To overcome this drawback, a hybrid method is proposed by integrating the concepts of fuzzy set theory, weight analysis and similarity value measure of fuzzy numbers. The analysis process is divided into two phases to identify the hazard source. The first phase uses fuzzy Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA), then the main potential failure modes can be determined. The importance analysis of basic events can be calculated using fuzzy set theory and weight analysis. In the second phase, the multiple failure modes and component correlations are modelled using the Fuzzy Risk Priority Number (FRPN) evaluation and the Similarity Measure Value Method (SMVM). The proposed method has been applied to the risk analysis of a satellite propulsion system to show the effectiveness and applicability.
Wittgenstein’s Vienna around 1900
Authors: Munz Volker 
Published: April 2018

Abstract:Even more than 60 years after his death the interest in Wittgenstein’s philosophy is still unbroken. Within the last two or three decades, however, we can observe an additional emphasis on the philosopher’s personality and his socio-cultural background. One way of explaining this development is the assumption that the work of an author, artist, or other intellectual cannot be separated from the person and his or her biographical setting. If this thesis is correct, one also has to take into account the lifeworld context within which any kind of intellectual oeuvre is ingrained. In this paper I try to give a very rough sketch of Wittgenstein’s Vienna and its socio-economic and cultural milieu around 1900.
Culture as a Monastic Rule
Authors: Albinus Lars 
Published: April 2018

Abstract:The German philosopher Peter Sloterdijk has taken a considerable interest in Wittgenstein’s concept of culture. The title of his book Du mußt dein Leben ändern, which is a quote from Rilke, also reflects one of Wittgenstein’s remarks, and Sloterdijk devotes a whole chapter to another quote, namely that “Culture is a monastic rule”, as Wittgenstein put it in 1948. Sloterdijk argues that Wittgenstein’s philosophy was, from the beginning, irreversibly formed by the secessionist movement in fin-de-siecle Vienna, and that he remained a cultural elitist at heart through his whole life. Thus Sloterdijk regards the concept of “language games” as ascetic instructions en miniature and reads Wittgenstein’s late philosophy as a veiled criticism of the so-called culture of his society, that is, “life forms” among ordinary language users who are blind to their own proclivities. I regard this interpretation as a gross misconception of Wittgenstein’s inclinations but also as a welcome opportunity to make some necessary distinctions between Wittgenstein’s views of culture in different phases of his philosophy.
On Certainty, Epistemic Incommensurability and Epistemic Relativism
Authors: Salvatore Nicola Claudio 
Published: April 2018

Abstract:In this paper, I present Wittgenstein’s remarks on the structure of reason, drawing on the notions of “hinges” he developed in On Certainty. I then outline some of the unpalatable relativistic consequences that can be extracted by Wittgenstein’s epistemological views. Then, developing the similarities between Wittgenstein’s treatment of “hinges” and his views on metrology and religious beliefs, I aim to show that his remarks on the structure of reason, once correctly understood and developed, can help us to block rather than license relativistic conclusions. I argue that following Wittgenstein’s views on epistemology, we should be able to dismiss all the cases of apparent unsolvable disagreement between communities committed to radically different worldviews; this is so because, once seen in the light of his conception of the structure of reason, these disagreements are either solvable, as they are based on lack of knowledge and can thus be solved through education and training, or are mere pseudo-problems that stem from misguided comparisons between constitutively different language games and are thus the result of a misleading way of representing the nature and aim of our epistemic practices.
Voices of Resolution and Resistance in Indian Women’s Poetry
Authors: Uniyal Ranu 
Published: April 2018

Abstract
Contemporary Indian women’s writing is a challenge to existing male ethos and sexual ideology based on unequal power relations. Earlier domesticity and sexual relations were couched in silence and acceptance; today, they have become an intrinsic part of feminist discourse. Indian women poets converse in a language that threatens the status quo and propose to open up a separate space for those on the margins. The paper examines the essence of power dynamics in contemporary Indian women’s poetry in English. Poetry with its hidden metaphors and lilting images demonstrates an urge to dissolve the barrier between speech and silence. It also demands to be read differently. The desire to write leads to the ability to act with courage.
Alternative Literary Modernities: A Voice from Colonial Punjab
Authors: Minocha Arti 
Published: April 2018

Abstract
This paper looks at the formation of colonial print publics in Punjab, the gendered subjectivities that emerged in this new discursive space, and middle-class women’s deployment of print to articulate the self. This will be done through a close reading of one of the first novels in English, Cosmopolitan Hinduani, which was published in Lahore, Punjab, by a woman in 1902. The essay examines the narrator’s notion of a gendered cosmopolitanism and the subject position that it affords, her attempt at going beyond the fault lines of religion to articulate a liberal and modern political subject, while reworking the cosmopolitan/local binary. How does her insertion of herself as a gendered subject in the provincial, national, cosmopolitan imaginary reflect in the author’s choice of language and genre? My attempt will be to see the novel and its author as part of a literary culture in which she made certain choices about the form, language, content, and audience.
