Job satisfaction in the multicultural environment of multinational corporations
PublikacjaPurpose – Since prior research into the effects of multiculturalism on job satisfaction in multinational corporations (MNCs) is rather scant and inconclusive, the authors attempt to review the literature and explain why these results are inconsistent as well as propose a new model aimed at responding to these irregularities. Design/methodology/approach – In the narrative review of the prior research and the proposed model the...

Analysis of IPv6 handovers in IEEE 802.16 environment
PublikacjaThe second generation of WiMAX solutions, based on IEEE 802.16-2005 standard, offers limited mobility support. Unfortunately, after quickly changing the point of attachment on the WiMAX data link layer (DLL), very slow and inefficient IPv6 reconfiguration takes place. Delays introduced by automatic configuration (DHCPv6 and IPv6 protocols) and Mobile IPv6 can easily diminish or even render useless all benefits gained using the...

Development of an Analytical Protocol for Determination of Cyanide in Human Biological Samples Based on Application of Ion Chromatography with Pulsed Amperometric Detection
PublikacjaA simple and accurate ion chromatography (IC) method with pulsed amperometric detection (PAD) was proposed for the determination of cyanide ion in urine, sweat, and saliva samples. The sample pretreatment relies on alkaline digestion and application of Dionex OnGuard II H cartridge. Under the optimized conditions, the method showed good linearity in the range of 1–100 μg/L for urine, 5–100 μg/L for saliva, and 3–100 μg/L for sweat...

Entropy Production Associated with Aggregation into Granules in a Subdiffusive Environment
PublikacjaWe study the entropy production that is associated with the growing or shrinking of a small granule in, for instance, a colloidal suspension or in an aggregating polymer chain. A granule will fluctuate in size when the energy of binding is comparable to k_{B}T, which is the “quantum” of Brownian energy. Especially for polymers, the conformational energy landscape is often rough and has been commonly modeled as being self-similar...

Application of passive sampling techniques for monitoring the aquatic environment
PublikacjaDozymetry pasywne są coraz powszechniej stosowanym narzędziem do pobierania próbek analitów ze środowiska wodnego. W przypadku próbników pasywnych pobieranie analitów następuje na drodze swobodnego transportu masy przez membranę do medium zatrzymującego, na skutek różnicy potencjałów chemicznych analitów w medium zatrzymującym w próbniku i środowiskiem wodnym, w którym umieszczany jest próbnik. Największą zaletą stosowania próbników...
