The goal of INREP is to develop and deploy valid and robust alternatives to indium (In) based transparent conductive electrode materials as electrodes. In-based materials, mainly ITO, are technologically entrenched in the commercial manufacture of components like LEDs (both organic and inorganic), solar cells, touchscreens, so replacing them with In-free transparent conducting oxides (TCOs) will require holistic approach. The INREP philosophy is to meet this challenge by addressing the whole value chain via an application focused research programme aiming at developing tailor made solutions for each targeted application. This programme will produce a complete evaluation of the relevant properties of the proposed TCOs, including the impact of deposition technique, and by doing so, devise optimum processes for their application in selected, high value application areas. The selected application areas are organic and inorganic light emitting diodes (LEDs), solar cells and touchscreens. The physical properties of interest are the transparency, electrical conductivity, work function, texture, and chemical and thermal stability. To reach its overall goal, INREP brings together industrial and academic experts in TCOs, the technology and processes for their deposition and their applications in a concerted research programme that will result in the creation of TCOs and deposition technologies with the optimum opto-electrical properties suitable for the economic and safe manufacture of the specified photonic or opto-electronic components. The approach will include life cycle assessments of the environmental impact of the developed TCO materials and of their formation technologies over the entire period from application in manufacturing, throughcomponent operation into waste management.

Many epidemiological studies and reviews have been performed to identify the causes of bladder cancer. The aim of this review is to investigate the links between various environmental risk factors and cancer of the bladder. A systematic literature search was performed using PubMed, Science Direct, Scopus, Scholar Google and Russian Google databases to identify reviews and epidemiological studies on bladder cancer risk factors associated with the environment published between 1998 and 2010. Only literature discussing human studies was considered. Smoking, mainly cigarette smoking, is a well known risk factor for various diseases, including bladder cancer. Another factor strongly associated with bladder cancer is exposure to arsenic in drinking water at concentrations higher than 300 μg/l. The most notable risk factor for development of bladder cancer is occupational exposure to aromatic amines (2-naphthylamine, 4-aminobiphenyl and benzidine) and 4,4'-methylenebis(2-chloroaniline), which can be found in the products of the chemical, dye and rubber industries as well as in hair dyes, paints, fungicides, cigarette smoke, plastics, metals and motor vehicle exhaust. There are also data suggesting an effect from of other types of smoking besides cigarettes (cigar, pipe, Egyptian waterpipe, smokeless tobacco and environmental tobacco smoking), and other sources of arsenic exposure such as air, food, occupational hazards, and tobacco. Other studies show that hairdressers and barbers with occupational exposure to hair dyes experience enhanced risk of bladder cancer. For example, a study related to personal use of hair dyes demonstrates an elevated bladder cancer risk for people who used permanent hair dyes at least once a month, for one year or longer. Smoking, in particular from cigarettes, exposure to arsenic in drinking water, and occupational exposure to aromatic amines and 4,4'-methylenebis(2-chloroaniline) are well known risk factors for various diseases including bladder cancer. Although the number of chemicals related to occupational exposure is still growing, it is worth noting that it may take several years or decades between exposure and the subsequent cancer.

Caffeine is a psychoactive substance in daily human life which plays an important role in food and drug chemistry. The beverages such as coffee, tea, cola or drug formulations belong to the significant economic products in which the highest quality in international business is demanded. In respect to an ascending number of samples, the novel and perspective analytical methods for determination of caffeine providing accurate and reliable results are necessary. Electrochemical methods have been commonly exploited as cheap, rapid and simple alternatives to modern separation and spectral methods. To-date however, a comprehensive review on the electrochemical determination of caffeine has not been reported. Herein the present paper gives a summary on the current state in this field. The major part deals with the use of bare and modified carbon-based electrodes as voltammetric sensors for determination of caffeine. Amperometric, potentiometric and piezoelectric methods are also discussed in this review. © 2013 by ESG.

The Šesták-Berggren equation, representing a powerful tool for the description of kinetic data by the model-fitting methods, is analyzed. It is discussed that the exponents in the conversion function are non-integer in general and that the conversion function may not have a mechanistic interpretation. Within the framework of single-step approximation, the Šesták-Berggren equation enables to describe the kinetics of complex condensed-state processes without a deeper insight into their mechanism. © 2011 Elsevier B.V.

The main aim of this paper is to propose an FTV aggregation operator, which is a tool for aggregation of fuzzy truth values (fuzzy sets in [0,1]), and to provide a theoretical basis for the concept of FTV aggregation operator. We extend (ordinary) aggregation operator via convolution and show that the extension satisfies stated axioms, i.e. this approach leads to constructing of FTV aggregation operator. Furthermore, we show that our definition of FTV aggregation operator is an extension of usual definition of aggregation operator as well as of definition of aggregation operators for intervals and for n-dimensional intervals. © 2014 Elsevier Inc.
