Assessment of mineral liberation spectrum with all its aspects is essential for plant control and optimization. This paper aims to estimate 2D mineral map and its associated liberation spectrum of a particular chromite sample from optical micrographs by using Random Forest Classification a powerful machine-learning algorithm implemented on a user-friendly and an open-source software. This supervised classification method can be used to accurately generate 2D mineral map of this chromite sample. ...

The Precambrian metamorphic basement of the Istanbul-Zonguldak Unit (IZU) NW Anatolia Turkey is represented by the Sunnice Group composed essentially of four different metamorphic assemblages: (1) Cele metaophiolite (2) Yellice metavolcanics (3) Demirci metamorphics and (4) Dirgine metagranite. The field relations and structural characteristics of these units were studied and representative geochemical analyses of Cele metaophiolite and related volcanics were obtained from the Sunnice Almacik and ...

Electrical activity of myotubes represses nicotinic acetylcholine receptor (AChR) gene expression. This effect is mimicked by okadaic acid and blocked by tetrodotoxin (TTX) or staurosporine in cultured myocytes [Altiok et al. EMBO J. 16 (1997) 717-725]. In this study we investigated the mechanism of this repression. We show that addition of exogenous phospholipase D (PLD) and C inhibits AChR expression in a manner which parallels that of okadaic acid. Furthermore okadaic acid caused an increase ...

Formal Safety Assessment is a very important tool for the establishment of safety systems according to marine safety. FSA methodology has been recommended to all the maritime actors by the International Maritime Organization (IMO) as an integrated safety system. In Formal Safety Assessment two main risk methodologies are applied which are quantitative and qualitative risk assessments. Both of these methods are used together in practice. The FSA approach is applied in five main stages. In this study ...

This study examines the relationships similarities and differences among traditional advertising applications guerrilla art guerrilla marketing and guerrilla advertising all of which are interrelated. Guerrilla advertising differs from traditional advertising in that it is creative and allows for maximum turnover while spending the least amount of money since it is able to benefit from innovative strategies and promotional tactics. Guerrilla marketing employs various techniques which keep costs ...

Acute effects ofcadmium (Cd) and combined antioxidants were evaluated in Sprague-Dawley rat testes. The rats were subdivided into four groups. Cadmium chloride (2 mg/kg day) injected intraperitoneally during 8 days. Vitamin C (250 mg/kg day) vitamin E (250 rng/kgday) and sodium selenate (0.25 mg/kg day) were pretreated by gavage in both ofcontrol and cadmium injected rats. Testis lipid peroxidation and glutathione levels were determined by spectrophotometrically. In Cd treated rats lipid peroxidation ...

The aim of this study is to undertake an up-to-date assessment of market power in Central and Eastern European banking markets and explore how the global financial crisis has affected market power and what has been the impact of foreign ownership. Three main results emerge. First while there is some convergence in country-level market power during the pre-crisis period the onset of the global crisis has put an end to this process. Second bank-level market power appears to vary significantly with ...

The course concept introduced in this paper was implemented in 2011 in a university in Austria and shows an approach for integrating mobile learning modules in higher education. The results of the course as revealed in the research show the advantages as well as the potential for improvement of the system and its use in higher education. (C) 2013 The Authors.

Design has been in a period of change for the last decade but design education and more specifically design educators haven't kept up with these transformations. As a result design students continue to learn outdated methods and techniques. A designer needs to understand processes methods and mediums of design. At all of these levels the process is the same while methods may change slightly and the medium differs dramatically. Without expertise in mediums a designer is only able to facilitate what ...

This study analyzes the effect of interest and power structures and conflict of interest among managers and investors and tests the effect of different payout mechanisms on willingness to pay. In this study 74 student subjects are involved in a setting where the manager is determining his own compensation. A series of experiments that vary managers' ability to determine their own compensation and investors' ability to punish inappropriate behavior are reported. The experiments involve pairs of ...
