A NOVEL APPROACH TO FULLY CHARACTERIZE FIBER NETWORK MORPHOLOGY OF PLANAR FIBROUS TISSUES AND SCAFFOLDS
2011
Comprendere come la struttura di uno scaffold influenzi la morfologia cellulare e predirne il comportamento meccanico sono divenuti obiettivi fondamentali nello sviluppo dei tessuti ingegnerizzati. In questo studio si presenta un algoritmo innovativo basato su analisi d’immagine. Vengono introdotti descrittori di micro architettura che identificano univocamente la topologia della rete di fibre: orientamento delle fibre, connettività, densità spaziale delle intersezioni e diametro. Le prestazioni dell’algoritmo sono state valutate utilizzando immagini di microscopio a scansione elettronica (SEM) di (1) scaffolds in poliestere uretano-urea prodotti per elettrospinning, (2) gel di collagene se…

Tulkojumi ne dzimtajā valodā. Gadījuma analīze: Lubānas pašvaldības mājas lapas tulkojums
2018
Darba tēma: Tulkojumi ne dzimtajā valodā. Gadījuma analīze: Lubānas pašvaldības mājas lapas tulkojums. Darba mērķis: noskaidrot, vai, apzinot galvenās problēmas, kas rodas tulkojot tekstu ne dzimtajā valodā, iespējams sasniegt kvalitatīvāku rezultātu. Darbā tiek definēts dzimtās valodas jēdziens, apskatīts dzimtās valodas princips, precizēti galvenie pretargumenti tulkošanai ne dzimtajā valodā, noskaidroti iemesli, kāpēc cilvēki tulko svešvalodās un uzskaitīti galvenie teksta rediģēšanas pamatprincipi. Praktiskajā daļā tiek veikts Lubānas pašvaldības mājas lapas tulkojums vācu valodā un rediģēti tulkotie teksti. Tiek secināts, ka tulkotājam, lai veiktu tulkojumu ne dzimtajā valodā, galvenok…
The news consumption of digital natives
2015
Digitalization has shaped the newspaper market and nowadays the news consumption of people increasingly takes place in the online environment. At the same time when print newspapers can no longer be considered as the revenue drivers for media companies, especially digital natives remain reluctant to pay for news content in the digital media. As a result, the digitalization brought by the Internet is challenging the operations of media companies and they need to find new ways to attract consumers to using their services. Digital natives represent a generation that has grown up surrounded by the digital technologies and got used to utilizing the Internet for information collection. So far, th…
Frequency and Density-Dependent Selection on Life-History Strategies - A Field Experiment
2008
Negative frequency-dependence, which favors rare genotypes, promotes the maintenance of genetic variability and is of interest as a potential explanation for genetic differentiation. Density-dependent selection may also promote cyclic changes in frequencies of genotypes. Here we show evidence for both density-dependent and negative frequency-dependent selection on opposite life-history tactics (low or high reproductive effort, RE) in the bank vole (Myodes glareolus). Densitydependent selection was evident among the females with low RE, which were especially favored in low densities. Instead, both negative frequency-dependent and density-dependent selection were shown in females with high RE…
The Effect of Predator Population Dynamics on Batesian Mimicry Complexes.
2022
Understanding Batesian mimicry is a classic problem in evolutionary biology. In Batesian mimicry, a defended species (the model) is mimicked by an undefended species (the mimic). Prior theories have emphasized the role of predator behavior and learning as well as evolution in model-mimic complexes but have not examined the role of population dynamics in potentially governing the relative abundances and even persistence of model-mimic systems. Here, we examined the effect of the population dynamics of predators and alternative prey on the prevalence of warning-signaling prey composed of models and mimics. Using optimal foraging theory and signal detection theory, we found that the inclusion …
Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.
2011
Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…
Digital advertising around paid spaces, e-advertising industry’s revenue engine : A review and research agenda
2017
We develop and describe a framework for research in a particular segment of digital advertising. Internet Advertising Paid Slots and Spaces (IAPS) is a neologism and work almost like a stock exchange for buying and selling advertising in various formats on designated spaces around web and make a significant contribution to Internet advertising revenues. These paid spaces were found to encompass diverse areas of Internet advertising that include search engine marketing, social media advertising and display advertising. Given the complexity of the modern digital advertising eco system, this literature review seeks to provide clarity, up-to-date knowledge and ongoing insights into Internet adv…
Procedures for study of teaching practices. Literature Review
2012
Interest in studying teaching practices has increased, because of the need to evaluate teachers and dissatisfaction with the usual ways of doing it. Recent approaches with Value-Added Models, based on students’ results on achievement tests do not seem satisfactory. The article is based on a review of literature and classifies the approaches to practices in three groups: instruments based on information given by teachers; observation protocols; and approaches based on the analysis of products of the practices. Specific tools are described and advantages and disadvantages of the three approaches are discussed. El interés por las prácticas docentes ha aumentado, en parte por la necesidad de ev…

Le famiglie di soggetti autistici, le giovani donne affette da disturbi del comportamento alimentare, gli alcolisti, i tossicodipendenti, i giovani a rischio devianza dei quartieri degradati e coloro che usufruiscono delle misure alternative alla detenzione sono alcune degli attori che, venendo a far parte di nuovi aggregati identitari, mappano i contesti locali in spazi simbolici, in localitè, società urbane incomplete che rinviano a nuove questioni sociali e a differenti derive cui il welfare locale cerca di rispondere. Nel tentativo di esplicitare il groviglio fra solidarietà e povertà, capitalizzazione dei legami e inadeguatezza della rete, progettualità sociale e limiti organizzativi, …
