Identification of Novel Principles of Keratin Filament Network Turnover in Living Cells

2004

It is generally assumed that turnover of the keratin filament system occurs by exchange of subunits along its entire length throughout the cytoplasm. We now present evidence that a circumscribed submembranous compartment is actually the main site for network replenishment. This conclusion is based on the following observations in living cells synthesizing fluorescent keratin polypeptides: 1) Small keratin granules originate in close proximity to the plasma membrane and move toward the cell center in a continuous motion while elongating into flexible rod-like fragments that fuse with each other and integrate into the peripheral KF network. 2) Recurrence of fluorescence after photobleaching i…

Dominance of Chain Entanglement over Transient Sticking on Chain Dynamics in Hydrogen-Bonded Supramolecular Polymer Networks in the Melt

2018

The chain dynamics in supramolecular polymer networks is determined by the interplay of the kinetics of transient interchain association and relaxation of the network chains themselves. This interplay can be addressed by studying model supramolecular polymer networks in which the number of associative side groups and the molar mass of the covalently jointed backbone polymers are both varied systematically. To realize this idea, we use precursor chains with three different molar masses, which comes along with different extents of entanglement in the melt state. For each molar mass, the precursor polymers are functionalized with three different relative contents of associative side groups, gi…

Imaging of Keratin Dynamics during the Cell Cycle and in Response to Phosphatase Inhibition

2004

Publisher Summary The characterization and development of autofluorescent proteins, most prominently of the green florescent protein, have provided tools to label cellular structures such that they can be examined in living cells. This chapter highlights the potential of live cell imaging in providing novel and unprecedented insights into the dynamic organization of the keratin cytoskeleton and outlines the important aspects of this method. The live cell imaging experiments suggest that the driving force behind the vectorial and dynamic keratin distribution patterns relies both on microtubules and microfilaments and their associated factors. The studies on the dynamics of the keratin cytosk…

Preservation in Disaster Situations: a case study of the Valvilla Wool Mill Museum, Finland

2013

This article discusses the role of documentation and rescue planning in minimizing collection damages in disaster situations. The topic is surveyed through a case study of a fire that occurred in 2003 at the Valvilla Wool Mill museum in Hyvinkää, in Southern Finland. This incident caused significant damage to the authenticity and integrity of the museum’s archival collection. Both the fire and the extinguishing of the fire caused severe damage to items in the archival collection. Deterioration continued during aftercare, causing serious secondary collection damage because the methods of the first aid and aftercare were spontaneously planned and applied. By using the Valvilla Wool Mill museu…

An Interdisciplinary Approach to the Significance of Digital Economy for Competitiveness in Romanian Rural Area Through E-agriculture

2014

Abstract The digital economy is the key factor in the recovery of the EU economy and especially the Romanian economy. Based on its strengths in technology and knowledge, Europe should exploit the full potential of the digital economy. The digital economy offers great opportunities for SMEs in the manufacturing and service sectors. Therefore, an ambitious Digital Agenda, providing concrete steps to complete the online single market will be a key to sustainable economic recovery and social development of Europe. The understanding of what makes them a success or failure, and how much impact they may have in contributing to the wider rural economy is still relatively poorly developed. What is c…

Managing Municipal Solid Waste: Energetic and Environmetal Comparison among different options

2001

Goal. This research aims to assess the environmental effects of integrated strategies in a municipal waste management system. In particular, analysis is focused on a waste stream in Palermo, where landfill involves the prompt disposal of the most waste after collection. The current local management system is compared with two integrated waste management alternatives. Both the options comply with Italian regulations, but each one predicts adopting the available technologies in different ways. Methods and objectives. Energetic and environmental balances are carried out in each management system referring to local waste composition in order to quantify energy consumption, the recovery of mater…

Public procurement: current situation and points of improvement

2015

[ES] La construcción pública ha sido, es y será uno de los pilares fundamentales del sector construcción español, si bien la actual situación de crisis económica y la reducción de la inversión pública en nuevas infraestructuras ha generado un descenso de actividad hasta niveles similares a los años noventa. El retorno a índices de actividad más elevados no solo se conseguirá con la recuperación de la economía del país, sino que será necesario realizar ciertas mejoras en los procesos de licitación con objeto de conseguir una mayor funcionalidad y flexibilidad en la contratación pública de obras.

Sull’attuazione degli obblighi internazionali di risposta e ripresa a fronte della pandemia di Covid-19: una prospettiva italiana

2023

This work aims at offering a critical analysis of how Italy, as one of the most early-affected countries, has responded to and is currently recovering from the Covid-19 pandemic, in the framework of international and European obligations applicable to CBRN events at large. To this end, this article will first examine the main obligations concerning «response» to and «recovery» from a pandemic event, as stemming from relevant international and European law instruments. Then, it will look at how these obligations have been implemented by Italian central and local authorities vis-à-vis the Covid-19 pandemic, while also offering some conclusive remarks on the legal meaning of the «disaster mana…

Low-Head Hydropower for Energy Recovery in Wastewater Systems

2022

Hydraulic turbines for energy recovery in wastewater treatment plants, with relatively large discharges values and small head jumps, are usually screw Archimedes or Kaplan types. In the specific case of a small head jump (about 3 m) underlying a rectangular weir in the major Palermo (Italy) water treatment plant, a traditional Kaplan solution is compared with two other new proposals: a Hydrostatic Pressure Machine (HPM) located at the upstream channel and a cross-flow turbine (CFT) located in a specific underground room downstream of the same channel. The fluid mechanical formulations of the flow through these turbines are analyzed and the characteristic parameters are stated. Numerical ana…
