Piegādes ķēdes vadības efektivitātes novērtējums mazumtirdzniecības zīmolos: IKEA piemērs
2020
Mazumtirdzniecības nozares uzņēmumiem piegādes ķēdes vadība ir svarīgs aspekts. Tomēr joprojām daudziem no tiem ir grūtības ar efektīvās piegādes ķēdes novērtēšanas sistēmas radīšanu un ieviešanu. Šī darba galvenais mērķis ir izveidot dzīvotspējīgu piegādes ķēdes novērtēšanas sistēmas modeli mazumtirdzniecības uzņēmumiem. Darba gaitā autors ir izpētījis un izanalizējis pieejamu literatūru par piegādes ķēdes pārvaldību un tās novērtēšanas sistēmas efektivitāti, izpētījis esošo piegādes ķēdes novērtēšanas sistēmu IKEA uzņēmumā, kas kalpoja par pētījumu objektu, kā arī veicis intervijas ar nozares ekspertiem piegādes ķēžu pārvaldībā. Rezultātā autoram izdevās identificēt un klasificēt radītāju…
Synthesis of mesoporous silica nanoparticles (MSNs) and encapsulation of cisplatin for targeted cancer therapies
2014
The aim of this PhD thesis is to elaborate mesoporous silica nanoparticles (MSNs) able to sustain the release of cisplatin into the intracellular compartments of solid tumors. The parametric study shows that morphological, structural and textural properties of MSNs-MCM-41, synthesized by sol-gel reaction by using TEOS as a silica source and CTAB as a structure-directing agent, depend on pH, stirring speed, temperature and extraction process of CTAB. The synthesis atmosphere has to be controlled in order to avoid the presence of ethanol and carbonate species which are responsible of necks between particles generating unstable suspensions of MSNs.MSNs were functionalized in order to control t…
Molecular docking and pharmacogenomics of vinca alkaloids and their monomeric precursors, vindoline and catharanthine.
2011
International audience; Vinblastine and vincristine are dimeric indole alkaloids derived from (formerly: ). Their monomeric precursor molecules are vindoline and catharanthine. While vinblastine and vincristine are well-known mitotic spindle poisons, not much is known about vindoline and catharanthine. Vindoline and catharanthine showed weak cytotoxicity, while vinblastine, vincristine, and the semisynthetic vindesine and vinorelbine revealed high cytotoxicity towards cancer cells. This may reflect a general biological principle of poisonous plants. Highly toxic compounds are not only active towards predators, but also towards plant tissues. Hence, plants need mechanisms to protect themselv…
Mesoscopic and Microscopic Investigation on Poly(vinyl alcohol) Hydrogels in the Presence of Sodium Decylsulfate
2007
The structure of poly(vinyl alcohol) (PVA) hydrogels formed as a result of freeze/thaw treatments of aqueous solutions of the polymer (11 wt % PVA) in the freshly prepared state is analyzed through the combined use of small (SANS) and ultrasmall (USANS) angle neutron scattering techniques. The structure of these hydrogels may be described in terms of polymer rich regions, with dimensions of the order of 1-2 microm, dispersed in a water rich phase, forming two bicontinuous phases. The PVA chains in the polymer rich phase form a network where the cross-linking points are mainly crystalline aggregates of PVA having average dimensions of approximately 45 A. The structural organization of freeze…

Digitalisation of municipal healthcare collaboration with volunteers: a case study applying normalization process theory
2021
Abstract Background Increasing use of volunteers in healthcare requires structured collaboration between healthcare services and volunteers. The aim of this research was to explore critical issues and strategies in the implementation process of a digital solution for collaboration with and coordination of volunteers in municipal healthcare services. Methods Qualitative data collection was used to study implementation of a digital system for collaboration with volunteers in three Norwegian municipalities. Three rounds of interviews were conducted with healthcare employees from a volunteer centre and from municipality healthcare units in three municipalities: before implementation, and 6 and …
Key challenges and best practices in the coordination of volunteers in healthcare services: A qualitative systematic review.
2020
Cooperation between voluntary organisations and volunteers within healthcare services contributes to the development of public welfare. The coordination process between healthcare services and volunteers must therefore be studied to understand associated challenges and best practices. This paper presents a systematic literature review of studies that have used qualitative methods. The review was conducted to identify the knowledge base concerning these issues. The search was performed in 4 April 2019 on five databases: EbscoHost, Ovid, Scopus, Emerald and Svemed+. The selection criteria included papers published between 1 January 2009 and 4 April 2019. In total, 5,340 papers were extracted;…
Semantic Web Services for Smart Devices in a “Global Understanding Environment”
2003
Various Web resources and services are usually assumed to be used and accessed by human users (current Web) or by software agents on behalf of human users (emerging Semantic Web). However industry emerges also a new group of “users”, which are smart industrial devices, robots or any other objects, which can be adapted to the (Semantic) Web environment. They would need special services for e.g. online condition monitoring, information provisioning, remote diagnostics, maintenance support, etc. The goal of this paper is to specify main requirements to Web services that automatically follow up and predict the performance and maintenance needs of field devices. Semantic Web enabled services for…

Multilingual information delivery based on a domain ontology
2014
As internationalisation becomes more and more intensive, organizations need to work with information in different languages in their work. Interlingua content delivery in e-learning courses could be effective learning content adaption method for delivering information for much wider audience. This paper suggests high-level framework for multilingual learning content delivery. This approach is based on a domain ontology, which allows to annotate and retrieve learning resources in a language independent way. Such method can improve accessibility, sharing and reuse of multilingual learning content.
