Lionello Perera: An Italian Banker and Patron in New York
2022
The book presents the long-lost biography of Lionello Perera, principal banker, patron, and philanthropist of the Italian American community in New York at the inception of the twentieth century. Born and raised in Venice, Lionello Perera took over his uncle’s financial activity in Wall Street and developed the family business into a stronghold of the Italian American community. His remarkable career led him to become the Vice President of Bank of America in 1928 as an associate of California born Amadeo P. Giannini, while he also was instrumental to the political success of New York mayor Fiorello La Guardia. Recognised as a true founding father of the Italian American community of the Eas…
Fatigue Design of Cruciform Joints including V-notch Effect at the Weld Toe
2014
Abstract The present paper proposes a new and more accurate fatigue life prediction model for fillet welded joints in steel subjected to constant amplitude loading. With the traditional fracture mechanics approach, the greatest difficulty when computing the fatigue life of a welded detail is to determine the initial crack size a0. The classical way to determine the stress intensity factor K (SIF) is by using the following formula Where σ is the applied stress, a is the crack size and g(a/T) the geometrical correction factor which has been determined by Gurney function or similar solutions. This approach is not accurate for short crack because of the singular V-notch behaviour close to the c…
Storia dell'Arte in Europa. Inghilterra
2014
Il saggio si offre come guida alla lettura dei maggiori fenomeni artistici fioriti in Inghilterra nel XIX secolo e affronta la genesi e lo sviluppo di tendenze e movimenti straordinari che si estendono dal Gothic Revival alle Arts and Crafts, dai Preraffaelliti all'Aesthetic Movement, dal Japonisme all'Art Nouveau. Il volume, ampiamente illustrato e corredato di bibliografia aggiornata, traccia un quadro storico-critico dell'età vittoriana senza tralasciare l'analisi delle maggiori opere d'arte dell'epoca, realizzata da artisti quali William Morris, Dante Gabriel Rossetti, Albert Moore, Lawrence Alma-Tadema, Aubrey Beardsley e molti altri autori, oggi al centro di un rinnovato interesse da …
Illegitimate tasks, job crafting and their longitudinal relationships with meaning of work
2021
The aims of this study were twofold: first, to investigate whether illegitimate tasks and job crafting are associated longitudinally with meaning of work, and, second, to explore whether job crafti...
Job change without changing job? Exploring job crafting in Spain
2014
El document de treball analitza el “job crafting” i la seva validesa convergent amb el “work engagement” i la personalitat proactiva a Espanya. Basat en el model de demandes i recursos laborals (Job Demands-Resources model) amb quatre dimensions (augment dels recursos estructurals del treball, disminucio de les demandes de treball, augment dels recursos socials del treball i creixent demanda dels reptes del treball), el document de treball valida una escala de “job crafting” a partir d’una mostra de 896 treballadors d’empreses a Espanya. Els resultats de l’analisi factorial confirmatori i d’invariancia suggereixen que el model de quatre factors descriu satisfactoriament l’estructura dimensi…
Hemocyte types and some plasmatic properties of two edible crabs Cancer borealis and Cancer pagurus
2015
Cancer pagurus and Cancer borealis and are edible crabs produced by economically relevant aquaculture. In this study the hemocytes and some plasmatic parameters of Cancer borealis and Cancer pagurus were examined. The cell features of the hemocytes were observed using light and scanning electron microscopy (SEM). Granulocytes, semigranulocytes and hyalinocytes were mainly identified on the basis of size, presence/absence and quantity of the cytoplasmic granules and the nucleus-to-citoplasma (N/C) ratio. SEM observations were useful for disclosing the surface features of these cells, and the same characteristics were found in both crab species. A smooth surface distinguishes elongated hyalin…
Former for lek En empirisk analyse av møtet mellom barn og åpen form.
2015
Masteroppgave kunstfag- Universitetet i Agder, 2015 Denne oppgaven kan leses som et møte mellom barn og åpen form. Empirien utgjør materialet fra en observasjon der barn i en barnehage får nye formelementer som er laget spesielt for denne oppgaven. Problemstillingen i oppgaven er Hvordan kan åpne former skape fantasi i barns lek? Utgangspunktet er at barn kan leke med apparater og leketøy som enten har en bestemt funksjon, eller en mer åpen utforming, der gjenstanden ikke nødvendigvis viser at er noe, nærmere bestemt har en åpen form. I pedagogikken til Friedrich Frøbel fremholdes de åpne formene som fordelaktige, da de skaper fantasi og læring. Oppgaven viser også til kunstneren Gjedrem, s…
Data from: Plant – herbivorous beetle networks: molecular characterization of trophic ecology within a threatened steppic environment
2015
DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…
Human endothelial cell-based assay for endotoxin as sensitive as the conventional Limulus Amebocyte Lysate assay
2014
AbstractEndotoxin, also known as lipopolysaccharide (LPS) produced by bacteria can be present in any liquid or on any biomaterial even if the material is sterile. Endotoxin in mammals can cause fever, inflammation, cell and tissue damage and irreversible septic shock and death. In the body, endothelial cells making up the blood vasculature and endothelial cells in vitro rapidly react to minute amounts of endotoxin resulting in a rapid induction of the cell adhesion molecule E-selectin. In this study we have used immunofluorescent staining to evaluate the expression of E-selectin on human microvascular endothelial cells from the skin (HDMEC) and human umbilical vein endothelial cells (HUVEC)…
Hydrogen emissions from Erebus volcano, Antarctica
2012
International audience; The continuous measurement of molecular hydrogen (H2) emissions from passively degassing volcanoes has recently been made possible using a new generation of low-cost electrochemical sensors. We have used such sensors to measure H2, along with SO2, H2O and CO2, in the gas and aerosol plume emitted from the phonolite lava lake at Erebus volcano, Antarctica. The measurements were made at the crater rim between December 2010 and January 2011. Combined with measurements of the long-term SO2 emission rate for Erebus, they indicate a characteristic H2 flux of 0.03 kg s-1 (2.8 Mg day-1). The observed H2 content in the plume is consistent with previous estimates of redox cond…
