Reducing whole-body vibration exposure in backhoe loaders by education of operators

2012

Author's version of an article published in the journal: International Journal of Industrial Ergonomics. Also available from the publisher at: http://dx.doi.org/10.1016/j.ergon.2012.03.001 Whole-body vibration is a health hazard for operators of construction machinery. The level of whole-body vibration exposure on the operator is governed by three different factors; performance of the suspension system of the machine, planning of the work and the skills of the operator.In this research work it is investigated whether there is a potential in bringing down the level of whole-body vibration exposure by educating operators of backhoe loaders. This is carried out by an experimental setup. Six ex…

Le sens du regard Contribution sémiotique à la technique de l'eye-tracking face aux packagings produits

2009

International audience; This work is presenting a semiotic point of view of a promising but problematic tool of the communication field -eye-tracking- which is used in various fields to track and exploit the eye-path on an object. Drawing form a list of eye-paths on various packagings, the first step of the analysis was the identification without theoretical a priori- of fixed patterns in these paths. Several models can then be inferred on how the order of acquisition of the elements of an image or a pack might have an influence on the construction of their overall meaning.; Ce travail propose un point de vue sémiotique sur un outil du champ de la communication prometteur mais problématique…

Dynamische kulturelle Prozesse. Peripherisierung und Entperipherisierung der Insel Rügen

2017

The flow of the communication and the flow of the medial communication take part in the processes of marginalization or centralization. The present construction of space and its actual classification is then introduced on grounds of testimonies of written words (the individual statements in letters, lyrics, journalism). This paper presents the progressing cultural marginalization of the Island landscape of Pomerania, and especially of the Island Rugen taking into account the three following phases: 1. Devaluation or evaluation of the north in the period of the Middle Ages and the early Modern Era in the context of the Christian mission and the Bible representation of order; 2. The beginning…

Interaction of construction costs and output in Latvia

2020

Growth of an economy is strongly linked with the growth of the construction sector. An increased construction output must influence the costs in this area. Analysis of the construction output and construction costs in Latvia for the time period since 2006 until 2017 shows an average effect. The main goal is to forecast construction costs and output in Latvia. Comparative analysis of costs and output dynamics was done, and a general trend can be proven, but heteroscedasticity is being observed. The effect of construction output on costs is limited in scale, but similar in general tendency and author offers his discussion for possible reasons for inconsistencies in construction sector changes.

Conoscenza, conservazione, valorizzazione: criticità, processi e approccio unitario

2014

Conoscenza, conservazione e valorizzazione sono obiettivi distinti ma inseparabili; essi si sono sviluppati durante gli ultimi tre secoli con motivazioni collegate a diversi punti della “linea del tempo”: si deve conoscere qualcosa in modo peculiare perché si differenzia dal resto dell’ambiente costruito, in quanto è una testimonianza del Passato; questo qualcosa è vulnerabile, pertanto si deve proteggere per poterlo trasmettere al Futuro; la valorizzazione è un obiettivo relativamente più recente, che si concentra sul Presente, spingendo a integrare il patrimonio architettonico con la vita contemporanea. Oggi ci troviamo a perseguire nello stesso tempo questi tre obiettivi, tutti urgenti e…

Building the Defenses. The Construction Sites of the Fortifications of Trapani and Palermo in the First Decades of 16th Century

2016

La registrazione quotidiana di tutti i costi, comprese le retribuzioni dei lavoratori, era una prassi nei cantieri delle fortificazioni in Sicilia. Sfortunatamente questi registri sono andati perduti, con l'eccezione di un volume che registra i conti per la costruzione delle fortificazioni di Trapani nel 1527 e nel 1528, e altri due relativi a Palermo, che datano tra il 12 novembre del 1536 r il 23 agosto del 1539. Il registro relativo alle mura di Trapani testimonia l'andamento dei lavori di quello che può essere considerato il primo progetto in Sicilia per l'intero ridisegno delle difese urbiche secondo i principi della fortificazione all'italiana, e di certo la più importante opera dell'…

La difficile costruzione della chiesa nuova nell'abbazia di San Martino delle scale: contrasti, testimonianze, perizie (1576-1598)

2015

A partire dal 1561 nel complesso benedettino di San Martino delle Scale, presso Palermo, si avvia la costruzione di una nuova chiesa, portata a compimento e inaugurata soltanto nel 1602. Una variegata documentazione d’archivio restituisce i principali passaggi del tormentato iter esecutivo dell’opera, articolato in più tappe che vedono l’avvicendarsi di diversi sodalizi di maestri costruttori al vertice del cantiere. Testimonianze, memoriali e relazioni presentati e discussi, tra 1576 e 1598, in liti giudiziarie intentate dai monaci nei riguardi dei maestri costruttori offrono interessanti spunti per una più ampia riflessione sul tema delle perizie. Nello spazio di poco più di vent’anni la …

Copper( ii ) complexes with phosphorylated 1,10-phenanthrolines: from molecules to infinite supramolecular arrays

2016

International audience; The reaction of phosphorylated 1,10-phenanthrolines 3-Pphen, 3,8-Pphen and 4,7-Pphen (3-Pphen = 3-diethoxyphosphorylphenanthroline, 3,8-Pphen = 3,8-bis(diethoxyphosphoryl) phenanthroline, 4,7-Pphen = 4,7-bis(diethoxyphosphoryl) phenanthroline) and hydrated copper(II) nitrate in a 1 : 1 ratio leads to the formation of supramolecular architectures. In the 1D coordination polymer [Cu(3-Pphen)(NO3)(2)](n) (2) the copper atom is coordinated to only one phenanthroline ligand and the coordination sphere is completed by two oxygen atoms of nitrate anions and the oxygen atom of the phosphoryl group from the neighbouring phenanthroline ligand. Complex Cu(3,8-Pphen)(NO3)(2) (3)…

Construction stages of cable-stayed bridges with composite deck

2012

A cable-stayed bridge is built by following a construction sequence of different subsequent stages that imply changes of the geometric configuration, restraints and consequently stress and strain patterns. A study is presented about stay stressing sequences in cable-stayed bridges with composite deck for the case of construction made by the cantilever method. Initial cable forces are found through partial elastic schemes of construction stages. Different stay stressing procedures are implemented and a comparison between them is proposed in order to evaluate the differences in terms of deformed shape and internal force distribution of the deck and the pylon. Results can be useful to give pra…
