Organic dyes are common constituents in wastewater and contribute to accumulation of persistent organic pollutants in the environment. Common dyes are aromatic compounds, bearing a variety of hydrophilic functional groups. Their interaction with solid surfaces can thus involve both van-der-Waals and hydrophobic interactions and electrostatic and/or hydrogen bonding. Aiming to tailor adsorbents with specific capacity for removal of dyes, silica microspheres were synthesized, combining aminopropyl ...

The concept of Corporate Social Responsibility covers a wide range of actions which have been practiced for many years in Western countries. As well as in other developing and transitional countries, the concept of social responsibility emerged in Romania after 1990, concurrently with the set-up of many non-governmental organizations (NGOs) and the entrance of multinational companies and was rapidly adopted by several firms. The main purpose of our paper is to investigate practices and actions related ...

Spherical silica particles with bifunctional (≡Si(CH 2 ) 3 NH 2 /≡SiCH 3 , ≡Si(CH 2 ) 3 NH 2 /≡Si(CH 2 ) 2 (CF 2 ) 5 CF 3 ) surface layers were produced by a one-step approach using a modified Stöber method in three-component alkoxysilane systems, resulting in greatly increased contents of functional components. The content of functional groups and thermal stability of the surface layers were analyzed by diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy, and 13 C and 29 Si solid-state NMR spectroscopy ...

Spherical silica particles with bifunctional (Si(CH2)3NH2/SiC6H5) surface layers were synthesized by the Stöber method using ternary alkoxysilanes systems. The influence of the synthesis conditions, such as temperature and stirring time on the process of nanoparticles formation was studied. The presence of introduced functional groups was confirmed by FTIR. The composition of the surface layers examined by elemental analysis and acid-base titration was shown to be independent from the synthesis temperature. ...

Tubular porous ceramic substrates based on crystalline SiO2 were successfully functionalized with amino and mercapto functions using the one-step sol-gel approach. The samples were analyzed by SEM, FT-IR spectroscopy, low-temperature nitrogen adsorption-desorption to reveal their structure and composition. It was shown, that the functional layers of such materials contain silica nanoparticles with amino and mercapto groups, and their porosity can be varied regarding the nature of the structuring ...

The multidimensional construct of perfectionism is well studied as it relates to coping with stress and burnout (Childs & Stoeber 2012; Flett & Hewitt 2002). Bontempo and Napier (2011) identify the personality trait of conscientiousness, which includes perfectionistic traits, as beneficial to an interpreter’s job performance. In contrast, several studies suggest that constructs related to maladaptive perfectionistic traits play a role in the development of burnout among interpreters, although perfectionism ...

Operant conditioning is a common tool for studying cognitive aspects of brain functions. As the first step toward understanding those functions in simple invertebrate microbrains, we tested whether operant conditioning could be applied to train American lobster Homarus americanus that has been extensively adopted as an animal model for neurophysiological analyses of nervous system functions and behavioral control. The animal was trained by food rewarding for gripping of a sensor bar as the operant ...

Moreover, studies on Romanian CSR demonstrate the incremental development of such practices, while the social responsibility of Romanian small business is an understudied topic. In this paper we present data regarding the role of owner-managers in shaping the CSR actions ...

Animals generally exhibit circadian rhythms of locomotor activity. They initiate locomotor behavior not only reflexively in response to external stimuli but also spontaneously in the absence of any specific stimulus. The neuronal mechanisms underlying circadian locomotor activity can, therefore, be based on the rhythmic changes in either reflexive efficacy or endogenous activity. In crayfish Procambarus clarkii, it can be determined by analyzing electromyographic (EMG) patterns of walking legs whether ...

Chicken cholera usually occurs in septic form, and causes high morbidity and mortality (60–80%), but recently it has become chronic, subclinical and associated. Inactivated emulsion vaccines are used worldwide to prevent chicken cholera and provide high and long-term immunity. However, there is a problem with residual reactogenicity of inactivated ...
