The circular economy (CE) as an idea involves applying the concept of sustainable development that has been gaining worldwide support. This shift in perception energy and resource-use from its linear to forms creates a specific business environment, which constitutes subject this research. article aims analyze impact manager’s on organizational wisdom, focusing model activity. In beginning, foc...

The present study was undertaken to provide more information on nucleolar changes induced by a histone deacetylase inhibitor such as valproic acid in leukaemic myeloblasts at the single-cell level. For this study, RNA in nucleoli was visualized by a simple but sensitive cytochemical procedure in unfixed cytospins of short-term bone marrow cultures from patients suffering from acute myeloid leuk...

In the recent years, e-learning gained popularity among educational institutions as well as enterprises. As the result of that many commercial or open-source Learning Management Systems (LMS) were developed to manage online courses. While the usage of these systems gains recognition and acceptance amongst institutions, there are new problems arising that need to be solved. Because of multiplici...

Uropathogenic Escherichia coli (UPEC) are capable of occupying physiologically distinct intracellular and extracellular niches within the urinary tract. This feat requires the timely regulation of gene expression and small RNAs (sRNAs) are known to mediate such rapid adjustments in response to changing environmental cues. This study aimed to uncover sRNA-mediated gene regulation in the UPEC str...

BACKGROUND The nutritional value of honey is a factor that encourages the increase of its consumption. The aim of the study was to identify consumers' behaviours and preferences towards honey and their determinants. METHODS Quantitative (PAPI method) survey was carried out in 2015 on a sample of 690 respondents from Mazowieckie, Podkarpackie and Zachodniopomorskie voivodeships. The data analy...

The ultimate goal of this research is to contribute to the understanding of spatial cognition and its consequences on locomotion (that is, on the organization of the whole organism's movements in space). An organism's locomotion depends on what structure it superimposes on space itself and can therefore be understood as a form of interaction with a subjective environment, understandable in turn...

Hardware performance monitoring (HPM) is a crucial ingredient of performance analysis tools. While there are interfaces like LIKWID, PAPI or the kernel interface perf_event which provide HPM access with some additional features, many higher level tools combine event counts with results retrieved from other sources like function call traces to derive (semi-)automatic performance advice. However,...

This paper describes the performance evaluation and analysis of a set of open source petascale quantum simulation tools for nanotechnology applications. The tools of interest are based on the existing realspace multigrid (RMG) method. In this work we take a reference set of these tools and evaluate their performance with the help of performance evaluation libraries and tools such as TAU and PAP...

Paragangliomas are tumors that originate from extra-adrenal medullary neural crest derivatives. They are rarely located in retroperitoneal space. These tumors are often discovered incidentally during imaging studies performed for other reasons. Periampullary cancers include adenocarcinomas arising from the pancreas, ampulla of Vater, duodenum or distal common bile duct. The exact site of origin...
