Comparative transcriptomics of albino and warningly‐coloured caterpillars
2021
Abstract Coloration is perhaps one of the most prominent adaptations for survival and reproduction of many taxa. Coloration is of particular importance for aposematic species, which rely on their coloring and patterning acting as a warning signal to deter predators. Most research has focused on the evolution of warning coloration by natural selection. However, little information is available for color mutants of aposematic species, particularly at the genomic level. Here, I compare the transcriptomes of albino mutant caterpillars of the aposematic wood tiger moth (Arctia plantaginis) to those of their full sibs having their distinctive orange‐black warning coloration. The results showed >29…
Work-related language learning trajectories of migrant cleaners in Finland
2017
Cleaning is often the survival employment that migrants can get in their new home country. Ideally, the workplace can be a site for integration and language learning. This article explores how two migrants working as cleaners in Finland narrate their work-related Finnish language learning trajectories. The research is designed by applying nexus analysis (Scollon & Scollon, 2004), which focuses on social action in the intersection of interaction order, participants’ life experiences, and discourses in place. The social action in focus here is investment (Darvin & Norton, 2015), which means a commitment to developing language skills to achieve one’s aspirations. The article also analy…
The Concept of Key Success Factors in Logistics and Supply Chain Management in the Context of Creating Business Competitive Advantage
2018
Firms are constantly looking for ways to create a competitive advantage. An important place among the factors affecting the way in which this advantage is gained is taken by success factors including, but not limited to, the so-called key success factors that may be related to the domains of logistics and supply chain management. The aim of the article is to identify the basic characteristics of the concept of key success factors in logistics and supply chain management. The article presents the essence and importance of success factors in the context of creating the business competitive advantage, the basic concepts of key success factors related to resource-based and market-based strategi…
Supramolecular Organocatalysis in Water Mediated by Macrocyclic Compounds
2018
In the last decades many efforts have been devoted to design supramolecular organocatalysts able to work in water as the reaction medium. The use of water as solvent provides promising benefits with respect to environmental impact. In this context, macrocyclic compounds played a role of primary importance thanks to their ease of synthesis and their molecular recognition abilities toward the reactants. The aim of this review is to give an overview of the recent advances in the field of supramolecular organocatalysis in water, focusing the attention on calixarene and cyclodextrins derivatives. Calixarenes and cyclodextrins, thanks to their hydrophobic cavities, are able to host selectively th…
Scattering of Co-Current Surface Waves on an Analogue Black Hole
2018
We report on what is to our knowledge the first scattering experiment of surface waves on an accelerating transcritical flow, which in the analogue gravity context is described by an effective spacetime with a black-hole horizon. This spacetime has been probed by an incident co-current wave, which partially scatters into an outgoing countercurrent wave on each side of the horizon. The measured scattering amplitudes are compatible with the predictions of the hydrodynamical theory, where the kinematical description in terms of the effective metric is exact.
Knowledge, attitude, and practice of the use of ready-to-eat vegetables among potential consumers of Palermo (Italy).
2007
The knowledge, attitude, and practice toward the use of ready-to-eat vegetables were evaluated in a sample of 701 (388 women and 313 men) potential consumers in Palermo, by answering to an anonymous questionnaire handed out. Food safety perceptions and behaviors were analysed; in general, interviewed consumers who perceived higher risks exhibited safer food behaviors. There weren't considerable differences in the use of these salads between two sexes; 81.4% of respondents uses these products to save a lot of time, particularly the graduates attach importance to saving in time (p = 0.001), and only 34.4% is worrying about high price. Statistical analysis showed a significant correlation betw…
The Graffiti Storyline and Urban Planning : Key Narratives in the Planning, Marketing, and News Texts of Santalahti and Hiedanranta
2018
This article regards urban planning as a form of storytelling and argues that there is significance in whose stories and which storylines are acknowledged to belong to the narrative fabric of a place and how the stories of future districts are communicated to the public through narratives during a planning project. My focus is on the storyline that follows the activity of graffiti culture in the two case areas of Santalahti and Hiedanranta (located in the city of Tampere in Finland) during these areas’ phases of transition created during the redevelopment of former industrial areas into residential districts. In my discursive analysis I identify key narratives that recur in planning, market…
Physics meets Bohemia Einstein in Bohemia Michael D. Gordin Princeton University Press, 2020. 360 pp.
2020
In Einstein in Bohemia, Michael Gordin seeks to illuminate the elusive significance of Einstein9s brief tenure in Prague, both for the biography of the famous physicist and for the cultural history of Bohemia. An expert in the history of modern physical sciences and of Russian, European, and American history, Gordin pulls together a wealth of information about the wider context of Einstein9s stay in Prague and of the cultural, scientific, and political history of Bohemia.
Stealth dicing with Bessel beams and beyond
2016
In the context of laser cutting of transparent materials, we investigate glass cleaving with Bessel beams and report that a modification of the beam with 3 main lobes drastically enhances cleavability and reduces defects.
Characteristics of Mesozoic fluvio-lacustrine formations of the western Central African Republic (Carnot Sandstones) by means of mineralogical and ex…
1990
Abstract The so-called Carnot Sandstones, Mesozoic fluvio-lacustrine detrital formation, which stretch over an area of more than 40 000 km 2 in the western part of the Central African Republic, are made of a succession of conglomerates, sandstones and argilites which can reach 300 m in thickness. Heavy mineral analyses and quartz exoscopic studies of this detrital material allow to understand the geology of these formations. The detrital material origin: heavy mineral distribution in the lower levels indicates mostly a meridional origin with a quantitatively poor peripheral supply. The importance of the transport: quartz exoscopic observations show that the main part of the detrital materia…
