The paper introduces and discusses the developed integrated economic model of municipal waste management of the Czech Republic, which was developed by authors as a balanced network model for a set of sources (mostly municipalities) of municipal solid waste connected with a set of chosen waste treatment facilities processing their waste.Model is imp
This article aims to identify how the critical success factors (CSF), barriers and practices for lean manufacturing (LM) implementation in a small company are related.For this, the CSF, barriers and practices of LM related to small companies were initially consolidated from a literature review.Through semi-structured interviews and focus groups wit
The vacuole is by far the largest intracellular Ca2+ store in most plant cells.Here, the current knowledge about the molecular mechanisms of vacuolar Ca2+ release and Ca2+ uptake is summarized, and how different vacuolar Ca2+ channels and Ca2+ pumps may contribute to Ca2+ signaling in plant cells is discussed.To provide a phylogenetic perspective,
This study was designed to assess liver-specific functions of human fetal liver cells proposed as a potential source for hepatocyte transplantation.Fetal liver cells were isolated from livers of different gestational ages (16-22 weeks), and the functions of cell preparations were evaluated by establishing primary cultures.We observed that 20- to 22
While a plethora of studies hbl5266ca have focused on the role of visual, chemical and near-field airborne signals in courtship of Drosophila fruit flies, the existence of substrate-borne vibrational signals has been almost completely overlooked.Here we describe substrate vibrations generated during courtship in three species of the D.melanogaster
