Sequent Depth Ratio of a B-Jump
2011
A B-jump is defined as the jump having the toe section located on a positively sloping upstream channel and the roller end on a downstream horizontal channel. This jump often occurs in the stilling basins with a horizontal bottom and located downstream of a steep channel. For a B-jump, a completely theoretical approach is not sufficient to solve the momentum equation and to establish the sequent depth ratio. In this paper, by using the laboratory measurements carried out in this investigation, some available empirical relationships useful for estimating the sequent depth ratio are tested. Then, by using the Π theorem of the dimensional analysis and the incomplete self-similarity theory, a g…
The mitotic kinase Aurora-A promotes distant metastases by inducing epithelial-to-mesenchymal transition in ERα+ breast cancer cells
2013
In this study, we demonstrate that constitutive activation of Raf-1 oncogenic signaling induces stabilization and accumulation of Aurora-A mitotic kinase that ultimately drives the transition from an epithelial to a highly invasive mesenchymal phenotype in estrogen receptor α-positive (ERα(+)) breast cancer cells. The transition from an epithelial- to a mesenchymal-like phenotype was characterized by reduced expression of ERα, HER-2/Neu overexpression and loss of CD24 surface receptor (CD24(-/low)). Importantly, expression of key epithelial-to-mesenchymal transition (EMT) markers and upregulation of the stemness gene SOX2 was linked to acquisition of stem cell-like properties such as the ab…
Ex-Ante Business Model Evaluation Methods: A Proposal of Improvement and Applicability
2019
[EN] Purpose: The purpose of this paper is to choose the best method for ex ante business model evaluation, improve it and provide a framework to put it into practice. Design/Methodology/Approach: After an in-depth review, we chose the best method for ex ante business model evaluation, improved this method, and applied it to a real case study in which business models had been proposed for a Sustainable Smart District project. Findings: We analysed existing ex ante business model evaluation methods, justifying our choice of the best one. We improved this key question-based method by combining classic management tools and a new, promising procedure. We finally found a strong tool to improve b…

Sobolev-Poincaré implies John

We establish necessary conditions for the validity of Sobolev-Poincaré type inequalities. We give a geometric characterisation for the validity of this inequality for simply connected plane domains.
The Triple Layered Business Model Canvas Meets the Beekeeping Sector. General and Particular Considerations from the Romanian Industry
2020
Abstract Today, sustainability has been clearly recognized as a necessity at global level by many, and the role of the business environment as a contributor in ensuring sustainability has become more and more acknowledged lately. Several efforts undertaken in this direction were focused on obtaining higher life quality levels and long-term benefits through businesses’ actions. Exploring and understanding agri-businesses from a managerial perspective becomes necessary due to sector’s particularities, but also to the fact that they are generally small enterprises, deeply embedded into their local communities. Beekeeping, as an agricultural branch, has indispensable contributions at societal a…
Exploring working memory in children with low arithmetical achievement
2005
Abstract This research aimed at exploring the working memory functions in children with low arithmetical achievement and normal reading, compared to age matched controls (mean age 9 years). All the children completed a series of working memory tasks, involving the central executive functions (using both linguistic and numerical material), the phonological loop (using words, pseudo-words and digits) and the visual sketchpad (using both static visual-spatial patterns and visual-spatial sequences). Results indicated that poor arithmeticians performed worse than age-matched controls in all the visual sketchpad tasks and in all the central executive tasks, whether they used linguistic or numeric…
Does Personality Smell? Accuracy of Personality Assessments Based on Body Odour
2012
People are able to assess some personality traits of others based on videotaped behaviour, short interaction or a photograph. In our study, we investigated the relationship between body odour and the Big Five personality dimensions and dominance. Sixty odour samples were assessed by 20 raters each. The main finding of the presented study is that for a few personality traits, the correlation between self–assessed personality of odour donors and judgments based on their body odour was above chance level. The correlations were strongest for extraversion (.36), neuroticism (.34) and dominance (.29). Further analyses showed that self–other agreement in assessments of neuroticism slightly differ…
Reservoir computing model of prefrontal cortex creates novel combinations of previous navigation sequences from hippocampal place-cell replay with sp…
2019
As rats learn to search for multiple sources of food or water in a complex environment, they generate increasingly efficient trajectories between reward sites. Such spatial navigation capacity involves the replay of hippocampal place-cells during awake states, generating small sequences of spatially related place-cell activity that we call “snippets”. These snippets occur primarily during sharp-wave-ripples (SWRs). Here we focus on the role of such replay events, as the animal is learning a traveling salesperson task (TSP) across multiple trials. We hypothesize that snippet replay generates synthetic data that can substantially expand and restructure the experience available and make learni…
Sociālās uzņēmējdarbības loma cilvēku ar invaliditāti nodarbinātības veicināšanā Latvijā
2022
Bakalaura darba tēma ir “Sociālās uzņēmējdarbības loma cilvēku ar invaliditāti nodarbinātības veicināšanā Latvijā”. Pētījuma mērķis ir noskaidrot, kāda ir sociālās uzņēmējdarbības ietekme uz cilvēku ar invaliditāti nodarbinātību. Lai sasniegtu pētījuma mērķi, kā pētījuma metode tika izvēlēta kvalitatīvā pētījuma metode – daļēji strukturētās intervijas ar sociālajiem uzņēmējiem un cilvēkiem ar invaliditāti, kuri strādā sociālajos uzņēmumos. Kā datu analīzes metode tika izmantota tematiskā analīze. Darbs tika balstīts uz invaliditātes sociālo modeli. Bakalaura darbā tika secināts tas, ka sociālajai uzņēmējdarbībai ir pozitīva ietekme uz cilvēku ar invaliditāti nodarbinātību, jo tā nodrošina c…
