Carlo Sbisà e il teatro

Analyzing the relations between Carlo Sbisà and the world of theatre, seems obvious to me that his interest for the scenes was born in his first youth and this is attested also by some of his first draws, today in the family’s collection. Furthermore, during the 40s and the 50s, he worked on the sketches for Trittico, lyrical theatre piece set for the first time in Trieste in 1949. Those sketches are today stored in the collection of Theatre’s Museum “Carlo Schmidl” of Trieste and my studies wish to contextualize them among his career and in relation to his artworks. Thanks to this focus, I had the pleasure to discover how his personal life story has been connected to the sphere of culture, music and, in particular, theatre

Stratocumulus cloud height variations determined from surface and satellite observations

Determination of cloud-top heights from satellite-inferred cloud-top temperatures is a relatively straightforward procedure for a well-behaved troposphere. The assumption of a monotonically decreasing temperature with increasing altitude is commonly used to assign a height to a given cloud-top temperature. In the hybrid bispectral threshold method, or HBTM, Minnis et al. (1987) assume that the lapse rate for the troposphere is -6.5/Kkm and that the surface temperature which calibrated this lapse rate is the 24 hour mean of the observed or modeled clear-sky, equivalent blackbody temperature. The International Satellite Cloud Climatology Project (ISCCP) algorithm (Rossow et al., 1988) attempts a more realistic assignment of height by utilizing interpolations of analyzed temperature fields from the National Meteorological Center (NMC) to determine the temperature at a given level over the region of interest. Neither these nor other techniques have been tested to any useful extent. The First ISCCP Regional Experiment (FIRE) Intensive Field Observations (IFO) provide an excellent opportunity to assess satellite-derived cloud height results because of the availability of both direct and indirect cloud-top altitude data of known accuracy. The variations of cloud-top altitude during the Marine Stratocumulus IFO (MSIFO, June 29 to July 19, 1987) derived from surface, aircraft, and satellite data are examined

Epidemiology and fitness effects of wood mouse herpesvirus in a natural host population

Rodent gammaherpesviruses have become important models for understanding human herpesvirus diseases. In particular, interactions between murid herpesvirus 4 and Mus musculus (a non-natural host species) have been extensively studied under controlled laboratory conditions. However, several fundamental aspects of murine gammaherpesvirus biology are not well understood, including how these viruses are transmitted from host to host, and their impacts on host fitness under natural conditions. Here, we investigate the epidemiology of a gammaherpesvirus in free-living wood mice (Apodemus sylvaticus) and bank voles (Myodes glareolus) in a 2-year longitudinal study. Wood mouse herpesvirus (WMHV) was the only herpesvirus detected and occurred frequently in wood mice and also less commonly in bank voles. Strikingly, WMHV infection probability was highest in reproductively active, heavy male mice. Infection risk also showed a repeatable seasonal pattern, peaking in spring and declining through the summer. We show that this seasonal decline can be at least partly attributed to reduced recapture of WMHV-infected adults. These results suggest that male reproductive behaviours could provide an important natural route of transmission for these viruses. They also suggest that gammaherpesvirus infection may have significant detrimental effects in wild hosts, questioning the view that these viruses have limited impacts in natural, co-evolved host species

Changes in the diet of hake associated with El Niño 1997?1998 in the northern Humboldt Current ecosystem

International audienceHake (Merluccius gayi peruanus) predation plays an important role in the dynamics of the Humboldt Current ecosystem (HCE). Changes in the hake trophic habits associated with physical variability are expected to impact prey populations and to propagate through the food web. Time series (1995?2002) of (a) stomach contents of hake, (b) biomass estimations of fish prey species of hake, and (c) depth of the 15°C isotherm was analysed with the aim of exploring the impacts of El Niño 1997?1998 on the diet of hake. Biomass estimations of fish prey species were used to indicate resource availability, and depth of the 15°C isotherm to represent variability associated with the ENSO cycle in the physical environment of hake. The richness of prey species increased during the months when 15°C isotherm reached its deepest position, supporting the hypothesis of increased biodiversity (tropicalization) of the HCE during El Niño events. An increased variability in stomach fullness of hake was detected after 1999 which could indicate high heterogeneity in the food supply as a consequence of impacts of the warm event in the biotic community structure of the HCE, a physiological impairment of hake or an effect of the abrupt reduction in the mean total length of hake, postulated as a compensatory response to fishery pressure. Hake can be characterized as an opportunist predator according to the observed changes in its diet during 1995?2002. Overall, the diet of hake in the northern HCE exhibited transitory (e.g. increased richness of prey species in the stomach contents) and medium term (e.g. increased variability in feeding activity) responses associated with El Niño 1997?1998, which should be incorporated both in population dynamics and food web analyses

Toimitusketjuhäiriöiden hallinta terveydenhuollossa : hankintojen johdon näkökulma

This thesis aims to give the reader a general idea of different methods used in managing risks and disruptions in supply chains, using the recent “COVID-2019”-pandemic as an example for a disruption in the healthcare sector. The theoretical background helps to understand what risks are in the context of supply chains, and how they can be prepared for. Alongside literature, three interviews were conducted where professionals from well-established organizations give their views on what is supply management, what are risks and how they protect themselves from them. The main theme in risk management was its broad nature, where issues appear spontaneously and in many shapes. Due to this, there are many methods and tools deployed to control the entirety of risks the company is exposed to, often governed by the values of the respective organization. It is possible to plan and build operations and supply chains to withstand disruptions, and when environmental factors change, different solutions can become opportunities. The factors defining the ability of specific process to withstand the disruption are resiliency and robustness. As noted in previous literacy, they are often used inter-changeably. However, this thesis gives us a further foothold to keep the two separated. A matter that should be elevated more by the management was tracking changes in the organization’s operational environment. The changes should be constantly monitored and changes to processes done accordingly. Another matter for management to consider is both the responsibility and ability of the management and leadership, in changing how the processes and values are set through organization’s culture.Tämän tutkielman tarkoituksena on antaa lukijalle pääpiirteittäinen ajatus siitä, millaisia työkaluja ja tapoja voidaan käyttää toimitusketjujen riskienhallinnassa. Esimerkkinä vakavasta toimitusketjuhäiriöstä käytetään ”COVID-19”-pandemiaa, joka nosti terveydenhuollon tarvikkeiden riittävyyden esille. Teoreettinen tausta auttaa lukijaa ymmärtämään mitä riskit ovat toimitusketjujen yhteydessä, sekä miten niihin voidaan varautua. Kirjallisuuskatsauksen tukena toimii kolmen eri organisaation riskienhallintaan tai toimitusketjuihin liittyvää johtohenkilöä, ketkä antavat näkemyksiään hankintojen johtamisesta sekä riskienhallinnasta ja niiltä suojautumisesta. Pääteemaksi muodostui riskienhallinnan laaja luonne, missä ongelmat ilmestyvät yllättäen ja moninaisesti. Näistä seikoista johtuen riskienhallinnassa käytettyjä työkaluja on monia organisaatioiden pyrkiessä hallitsemaan kokonaisuutta, ja nämä työkalut määräytyvät usein organisaation arvojen kautta. Organisaation on mahdollista suunnitella ja rakentaa toimintojaan sekä toimitusketjujaan kestämään häiriöitä, ja häiriöiden ilmaantuessa uusien toimintatapojen muodostaminen mahdollistuu. Tekijät, jotka määrittävät tätä häiriönkestävyyttä ovat kestävyys sekä joustavuus. Kuten aiempi kirjallisuus on maininnut, näitä termejä käytetään usein kuvaamaan toisiaan. Tämä tutkielma kuitenkin antaa lisää jalansijaa niiden erottamiselle toisistaan, sillä ne kuvaavat kahta erilaista tapaa kestää häiriöitä. Hankintojen johdon kannalta tärkeimmiksi seikoiksi nousivat organisaation toimintaympäristön seuranta, jonka avulla toimintatapoja muutetaan, sekä johdon rooli organisaation kulttuurimuutoksessa. Onnistuakseen uusien riskeihin liittyvien toimintatapojen ja asenteiden läpiviennissä, on johdon toimittava esimerkkinä organisaatiokulttuurin muutoksessa

Bone healing following different types of osteotomy: Scanning electron microscopy (SEM) and three-dimensional SEM analyses

The aim of the present study was to compare dynamics of the bone healing process after different types of osteotomies. In total, 24 Wistar rats were subjected to different types of osteotomy performed with standard steel bur, piezosurgery, contact, and non-contact Erbium:yttrium-aluminum-garnet (Er:YAG) laser ablation. The animals were randomly divided into four groups, to be euthanized immediately after the procedure, or at 1, 2, or 3 weeks after surgery. The obtained bone samples were analyzed by scanning electron microscopy (SEM). Immediately after surgery, there were significant differences in the appearance of the bone defects, with presence of bone fragments and debris after standard steel bur preparation, compared with the clean smooth walls and relatively sharp edges in all other groups. The initial bone formation in defects prepared by piezosurgery was observed to be the most rapid. After 3 weeks, all bone defects were completely restored; although, differences in the healing pattern were noted, with a modest initial delay in healing after laser preparation. The first stage of the bone healing process was delayed when contact and non-contact Er:YAG laser modes were used and accelerated by piezosurgery; however, the results after 3 weeks demonstrated similar restitution of defects in all tested groups
