A supported titanium postmetallocene catalyst: Effect of selected conditions on ethylene polymerization
2011
Ethylene polymerization with a titanium complex [N,N-ethylenebis(3-methoxysalicylideneiminato)titanium dichloride] immobilized on the magnesium support with the formula MgCl2(THF)0.32(Et2AlCl)0.36 was studied. In particular, the effects of polymerization temperature, monomer pressure, and polymerization time on the activity of the catalyst and on the polyethylene properties (molecular weight and its distribution, melting point, crystallinity, and bulk density) were evaluated. The findings of investigations prove that the studied supported titanium catalyst is highly active in ethylene polymerization, and its activity increases with increasing temperature and monomer pressure. Moreover, stab…
Realization of polyaspartamide-based nanoparticles and in vivo lung biodistribution evaluation of a loaded gucocorticoid after aerosolization in mice
2016
Abstract In this study, novel polymeric nanoparticles (NPs) were developed and their potential as carriers for beclomethasone dipropionate (BDP) into the lung after aerosolization was demonstrated by in vivo studies in mice. In particular, these NPs were obtained starting from two polyaspartamide-based copolymers which were synthesized by chemical reaction of α,β-poly(N-2-hydroxyethyl)- dl -aspartamide (PHEA) and its pegylated derivative (PHEA-PEG2000) with poly(lactic acid) (PLA). To obtain nanosized particles, the high pressure homogenization (HPH)—solvent evaporation method was followed by using an organic phase containing both PHEA-PLA and PHEA-PEG2000-PLA (at a weight ratio equal to 1:…
Effect of Hot Dip Galvanized Steel Surface Chemistry and Morphology on Titanium Hexafluoride Pretreatment
2017
Titanium hexafluoride pretreatments are known to improve paint adhesion and function as a barrier between the coating and the hot dip galvanized (HDG) steel surface. Interactions at the zinc/pretreatment interface are of utmost importance for the formation of pretreatment layers and the corrosion resistance of color coated hot dip galvanized steels. Removal rate of inert aluminum oxide from HDG steel samples by chemical dissolution was studied. XPS measurements showed that the surface Al2O3 layer thickness decreased rapidly already at mild alkaline cleaning, while complete removal of Al required severe etching. Low reactivity of an Al2O3-rich surface was confirmed by impaired formation of a…
Closed tank pneumatic press application to improve Sauvignon Blanc wine quality and nutraceutical properties
2019
The machines used in the winemaking process directly affect the quality of wine and its nutraceutical properties. Grapes-pressing is a very important step in winemaking as it may promote the presence and/or absence of enzymatic processes on the must, leading to the creation of different products in terms of chemical composition, starting from the same grapes. The aim of the study was to compare two different pressing systems of Sauvignon Blanc grapes using an innovative pneumatic discontinuous closed tank press in two operating modes: the traditional pressing mode in presence of oxygen and the inert pressing mode, performed through grapes pressing under inert gas with nitrogen recovery. Che…
Strategic renewal : Can it be done profitably?
2022
Industry transformation requires strategic renewal at the level of individual firms. Executives then face the dilemma of choosing renewal paths in the face of uncertainty over the competitive environment of the future, and hence the profitability of potential strategies. This dilemma motivates us to study industry transformation from the perspective of strategic renewal among 208 large firms in the global pulp and paper industry. The findings of our qualitative comparative analysis show that only a minority of firms in our sample succeeded in profitable proactive renewal. Content-wise, there were similarities in the pursued strategies over the wider population, but only a few maintained sup…
Crowdfunding performance, market performance, and the moderating roles of product innovativeness and experts' judgment: Evidence from the movie indus…
2023
Reward-based crowdfunding (CF) has emerged as a method to solicit funds for innovative projects. Yet, little is still known about the ability of reward-based CF to act as a signal in the eyes of future consumers, and thus boost the future market performance of new products that innovators intend to commercialize using the campaign funds. In addition, scant research has clarified the boundary conditions that can magnify or weaken the efficacy of this CF signal. Given the relevance of reward-based CF for supporting innovation, understanding when the CF campaign performance works as an effective signal is of great interest, especially in business settings characterized by high product quality …
Project Finance in the Energy Industry: An Integrated Approach to Credit Risk Assessment
2011
Project finance has emerged as a leading way to finance large projects in energy industry. The basic characteristic of project finance is that lenders loan money for the development of a project solely based on the specific project’s risks and future cash flows. This highlights a key feature of project finance due to the capacity to generate cash flows to ensure the repayment of loans and adequate returns on equity capital. A revenue stream from the project large enough is a prerequisite for project financing. The paper aims to assess the drivers of credit risk in project finance. Credit risk is one of the risks to which the project lenders are exposed. In particular, the proposed paper aim…
Factors Affecting the Consumers’ Purchase Intention and Willingness-to-Pay More for Electric-Vehicle Technology
2021
This study conducted an in-depth analysis of the factors affecting consumers’ intention to purchase and willingness to pay more for an electric vehicle (EV) in the developing-country context, extending the theory of planned behavior with two new variables: environmental concern and willingness to pay (WTP) a premium. Survey data were collected from 358 responses and were analyzed using partial least squares structural equation modeling. Multi-group analysis was conducted, and the moderating role of gender was examined. The findings showed the significant effects of the theory-of-planned-behavior variables and environmental concern on EV technology purchase intention. The present study provi…
Zu ausgewählten Aspekten der deutschen Eisenbahnterminologie
2020
Niniejszy artykuł prezentuje wybrane strategie nazewnicze, które wpływają na powstawanie terminów fachowych w branży kolejnictwa. Jednym z jego celów jest ukazanie, że forma tych pojęć jest w głównej mierze uzależniona od takich aspektów jak ekonomia językowa i ‘tendencja do uwidaczniania’. Krótki rys historyczny i szczególne podkreślenie znaczenia kognitywnej funkcji języków fachowych tworzą ramy niniejszej analizy, z jednej strony podkreślając wagę omawianego zagadnienia, z drugiej zaś wskazując na wielowymiarowy charakter uzyskanych wyników.
Einige Bemerkungen zu den produktivsten Wortbildungsstrategien in der deutschen Fachterminologie des Eisenbahnwesens unter der kontrastiven Berücksic…

Abstract This article is dedicated to present the most common word-formation strategies in German railway specialist terminology. The presentation of the most productive morphological nomination strategies in the analysed area is preceded by a short historical outline of the railway industry in Germany. The adumbration of the historical background and hints regarding the current EU environmental plans for railways are intended to expose the importance and relentless currency of the analysis undertaken here. The presented examples, which were extracted from the most extensive industry terminology database, RaiLLexic, have been correlated with their Polish equivalents. This contrastive proced…
