Engaging universities in social innovation research for understanding sustainability issues
2017
International audience; The paper presents the analysis of a three-stage research conducted by the authors within a social innovation project in collaboration with international master students of Riga Technical University for determining the factors, which motivate people to be involved in the solution of social problems. The authors not only analyse and use the outcomes of the students’ research but also provide feasibility study of using the potential of study research at the university, for implementing serious research projects. Data collection from Africa, Asia, America and Europe was organised jointly by all the students via web-based survey for creating an original data base for the…
Graphic model for evaluating the competitiveness and eco-efficiency of eco-innovative projects
2019
Eco-innovation describes the creation of novel and competitively priced goods, processes, systems, services, policies, and procedures that satisfy human needs and improve the quality of life while ensuring sustainable development with minimal use of natural resources and minimal release of toxic substances. This article delves into one of the most pressing problems in improving the assessment of eco-innovative projects meant to effect sustainable development. The article also proposes new criteria for evaluating eco-innovation projects. The purpose is to develop and propose a graphic model by which to assess the innovativeness, competitiveness, and eco-efficiency of eco-innovation projects.…
Evaluation of accounting regulation evolution in selected countries
2018
International audience; Accounting forms a significant part of information on any enterprise and plays the most important role in different levels of enterprise' management as well as in country's. Accounting information is used by various information users, whose decisions may influence various spheres: from performance of enterprises to proceeding the state policy. Its role increased recently under conditions of modern global and competitive market economy, and will be increasing in the future. Importance of accounting information usage highlights the need of appropriate formation of such information. And accounting regulation plays the main role in the process of formation and presentati…
Telemedicine the role of the patient-doctor relationship
The aim of this work is to study whether and how the characteristics of the existing relationship between a patient and her/his doctor impact the patient’s propensity to switch to telemedicine. We build a conceptual model which hypothesizes a direct effect of the patient-doctor relationship on the propensity to telemedicine, with the perceived efficacy of the healthcare service as the mediator. To collect data, we used the survey methodology. The results confirm the hypothesis about the positive effects of both a good patient-doctor relationship and the patients’ perceived value on the patients’ propensity to switch to telemedicine.
Synthesis and antiproliferative activities of two new analogs of tetrazepinones
Based on the encouraging results, we report the multistep synthesis and the biologicalo results of two new analogs of tetrazepinones: the 3,5-dimethyl-6-phenyl-8-(trifluoromethyl-5,6-dihydropyrazo1o[3-4-f]1,2,35)tetrazepin-4(3H)-one and the 3-(2-chloroethyl)-5-methyl-6-phenyl-8-(trifluoromethyl-5,6-dihydropyrazo1o[3-4-f]1,2,35)tetrazepin-4(3H)-one. Both compounds showed a pro-apoptotic activity against HL60 and K562 resistant cell lines. Flow cytometry studies carried out 0n K562 cells allowed to establish that the methyl derivative induces G0-G1, phase arrest followed by apoptosis, whereas the chloroethyl derivative is a not phase-specific agent.
Postsurgical Paracicatricial Cutaneous Satellitosis of Giant Cell Tumour of Tendon Sheath, Localized Type.
2011
The tenosynovial giant cell tumour (localized type) is a tumour of tendon sheaths and interphalangeal joints, affecting the digits and arising from the synovium. It is characterized by a proliferation of mononuclear cells and osteoclast-like polykaryocytes. Its propagation to the skin is an exceptional event, which can take place either in localized form in the fingertips (localized type) or in the rare diffuse form called giant cell tumour of the tendon sheath, ( diffuse type ). We report here a case of giant cell tumour with cutaneous satellites, which appeared close to and around the surgical scar following the excision of the primary lesion, in a 9-year-old boy. In the cutaneous satelli…
Estimates for Sums of Eigenvalues of the Free Plate via the Fourier Transform
2017
Using the Fourier transform, we obtain upper bounds for sums of eigenvalues of the free plate.
Inverse Malthusianism and Recycling Economics: The Case of the Textile Industry
2020
The current use of natural resources in the textile industry leads us to introduce a new economic concept called inverse Malthusianism describing a context in which population grows linearly and resource consumption grows exponentially. Inverse Malthusianism implies an exponential increase in environmental impact that recycling may contribute to reduce. Our main goal is to extend the analysis of materials selection under the principle of equimarginality proposed by Jevons. As a first result, we show the particular circumstances under which policies excluding recycled supplies are never optimal. We also aim to overcome the difficulties of reducing environmental aspects to monetary units. To …
Underlying Simple Graphs
2019
Summary In this article the notion of the underlying simple graph of a graph (as defined in [8]) is formalized in the Mizar system [5], along with some convenient variants. The property of a graph to be without decorators (as introduced in [7]) is formalized as well to serve as the base of graph enumerations in the future.
Automaton (Semi)groups (Basic Concepts)
2018
In this paper, we give an introduction to basic concepts of automaton semigroups. While we must note that this paper does not contain new results, it is focused on extended introduction in the subject and detailed examples.
