A systematic review of urinary bladder hypertrophy in experimental diabetes: Part 2. Comparison of animal models and functional consequences.
2018
Aims To explore whether the bladder hypertrophy consistently seen in rats upon streptozotocin injection also occurs in other animal models of type 1 or 2 diabetes and how hypertrophy is linked to functional alterations of the urinary bladder. Methods A systematic search for the key word combination "diabetes," "bladder," and "hypertrophy" was performed in PubMed; additional references were identified from reference lists of those publications. All papers were systematically extracted for relevant information. Results Models other than streptozotocin-injected rats and female animals have been poorly studied. Most animal models of diabetes exhibit less bladder hypertrophy as compared to strep…
Uterus transplantation: animal research and human possibilities
2012
Uterus transplantation research has been conducted toward its introduction in the human as a treatment of absolute uterine-factor infertility, which is considered to be the last frontier to conquer for infertility research. In this review we describe the patient populations that may benefit from uterus transplantation. The animal research on uterus transplantation conducted during the past two decades is summarized, and we describe our views regarding a future research-based human attempt.
Investigation of vehicle crash modeling techniques: theory and application
2013
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-013-5320-3 Creating a mathematical model of a vehicle crash is a task which involves considerations and analysis of different areas which need to be addressed because of the mathematical complexity of a crash event representation. Therefore, to simplify the analysis and enhance the modeling process, in this work, a brief overview of different vehicle crash modeling methodologies is proposed. The acceleration of a colliding vehicle is measured in its center of gravity—this crash pulse contains detailed informati…
The performance investigation of viscoelastic hybrid models in vehicle crash event representation
2011
Aurthor's version of a chapter published in the book: Proceedings of the 18th IFAC World Congress 2011. Also available from the publisher at: http://dx.doi.org/10.3182/20110828-6-IT-1002.00284 This paper presents application of physical models composed of springs, dampers and masses joined together in various arrangements to simulation of a real car collision with a rigid pole. Equations of motion of those systems are being established and subsequently solutions to obtained differential equations are formulated. We start with a general model consisting of two masses, two springs, and two dampers, and illustrate its application to represent fore-frame and aft-frame of a vehicle. Hybrid model…
The VFR Phenomenon in Italy
2015
The collection is the first book to explore research on visiting friends and relatives (VFR). In assembling an international collection of quality VFR-related research the editors present the profiles, characteristics, opportunities and behaviours of VFR travel for the benefit of researchers, industry practitioners and educators. This chapter discusses the characteristics of the phenomenon in Italy, by analysing official data as well as data drawn from purpose research.
Latvijas alus iespēju analīze eksportam uz Latīņameriku
2022
Maģistra darba tēma ir “Analīze par Latvijas alus eksporta iespējām Latīņamerikā”. Darba autore ir Jarlotte Camila Quintero Martinez un darba vadītājs - Prof., Erika Sumilo. Maģistra darba mērķis ir noteikt, kurš modelis tiks izmantots starptautiskā tirgus atlasei, un veikt Latīņamerikas tirgus izpēti, lai noskaidrotu, kura šī reģiona valsts būtu piemērotākā Latvijas alus eksportam. Lai sasniegtu maģistra darba mērķi, tiek veikta Latīņamerikas valstu izpēte, īstenota teorētiskā materiāla analīze par starptautisko tirgus atlases modeļu raksturojumu, kā arī riska pārvaldības un eksporta barjerām, tā rezultātā nosakot valsti ar labāko vidi Latvijas alus eksportam. Maģistra darbs sastāv no piec…
New Business Models In-The-Making in Extant MNCs: Digital Transformation in a Telco
2017
In recent years, we can observe the emergence of firms, born both digital and global, that have disrupted existing industries. Deploying digital technologies, they have developed innovative value chains and business models that threaten established multinational companies (MNCs). In this chapter, we examine how MNCs can and do respond to the challenge digital technologies represent. We describe the main facets of digital technologies and discus the potential these have to undermine the value chains and business models of established MNCs. In order to illustrate this, we employ longitudinal data from Telenor, a leading multinational mobile telecom company. Telenor perceives digitalization as…
Dialogues in partner abusive clients' group treatment: conversational tools used by counselors with differently motivated clients.
2014
This qualitative study investigated talk and interaction as process factors potentially influencing outcomes in abuser group intervention. The findings showed that (a) abusers participate in group programs with considerably different degrees of motivation; (b) the interaction in abusers’ various stages of change is characterized by different qualities; and (c) group counselors face a challenge in adapting their ways of working to abusers’ various needs and backgrounds. The findings demonstrate the importance of attending to the interactional elements in abuser treatment programs and show the value of matching an abuser’s needs and degree of motivation with the timing of interventions. It is…
Effects of COVID-19 on Business Models in Romania and the Netherlands, A Digitalization Perspective
2020
Abstract The research objective is to study how Romanian and Dutch organizations’ business models have changed under COVID-19 conditions. The role of digitalization in adapting business models and business practices is studied. The theoretical background reviews literature about business models and their dimensions. Literature review investigated digitalization in Romanian and Dutch organizations. Research questions were: To what extent do Romanian and Dutch organizations use: • more digital methods in their offer to their clients now than before the crisis? • more digital methods in their business processes now than before the crisis? • more digital methods in communicating with their clie…
Dynamic business modeling for sustainability: Exploring a system dynamics perspective to develop sustainable business models
2019
In the last decade, business models for sustainability have gained increasing attraction by corporate sustainability scholars with international conferences and scientific journals encouraging the development of the debate on their design, use and innovation processes. Capitalizing on the basic principles, requirements, and methodological limitations found in the literature on sustainability‐oriented business model design, this paper aims to conceptualize a dynamic business modeling for sustainability approach, which combines an adapted sustainable business model canvas and system dynamics modeling. To this end, the paper also illustrates the key operating principles of the proposed approac…
