Ohjelmistotyön tehostaminen automaatioympäristössä. Case: Jenkins

Tämän opinnäytetyön tarkoituksena oli toteuttaa Codecontrol Oy:lle avoimeen lähdekoodiin perustuvan web-pohjaisen Jenkins-palvelinsovelluksen asentaminen toimintakuntoon fyysiselle palvelimelle ja jakaa se usealle virtuaalipalvelimelle nykyisen yhden sijasta saaden kokonaisuus hyödyntämään master-slave -arkkitehtuurin mukaista ohjelmistoautomatisointimallia. Ennen varsinaista toteutusosuutta tämän opinnäytetyön teoriaosuudessa kerrotaan jatkuvasta integraatiosta ja jatkuvasta kehityksestä sekä niiden merkityksestä ohjelmistokehitykselle. Teoriaosuuden lopuksi esitellään toteutuksessa asennettava web-pohjainen palvelinsovellus Jenkins.The purpose of this thesis was to implement an open source web-based Jenkins server application installation into physical server for Codecontrol Oy and distribute it to multiple virtual servers instead of the existing one, thus enabling the whole utilization of the master-slave -architecture-based software automation model. Before the actual implementation part, the theoretical part of this thesis tells about continuous integration and continuous development and their significance for software development. Web-based server application Jenkins is introduced at the end of the theoretical part

X-ray powder diffraction quantitative analysis of anamorphous SiO2–poly(methyl methacrylate) nanocomposite

Quantification of individual phases within a multiphase amorphous material has been achieved using a newly developed technique based on X-ray powder diffraction. The quantification method was developed during a study of an amorphous silica-poly(methyl methacrylate) (SiO2-PMMA) hybrid nanocomposite. The efficiency of the method as a quantifying tool for individual phases was demonstrated for samples of SiO2-PMMA prepared either by polymerization of methyl methacrylate in the presence of amorphous SiO2 or by mechanically mixing known quantities of the individual and pre-prepared SiO2 and PMMA materials. The weight percentages of amorphous SiO2 in the nanocomposites as determined by application of the new technique were analogously found to be 29%, a result that was supported by thermogravimetric analysis and helium picnometry measurements

Structural properties of polysaccharide-based microcapsules for soft tissue regeneration

Autologous and eterologous cell encapsulation has been extensively studied for clinical application in functional organs substitution, recombinant cell transplantation in gene therapy or in muscle and cartilage regeneration to treat degenerative pathologies. In this work, calcium alginate, calcium alginate/chitosan, calcium alginate/ gelatin and pectin/chitosan microcapsules were prepared to be used as innovative injectable scaffolds for soft tissue regeneration by a simple extrusion method from aqueous solutions. Prepared microcapsules had spherical morphology, whereas their size was deeply influenced by the polymeric composition. When incubated in a physiological-like environment up to 30 days, they underwent an initial swelling, followed by weight loss at different rates, depending on the microcapsules formulation. The encapsulation of mouse myoblast cells (C2C12 cell line) was obtained in calcium alginate, calcium alginate/chitosan, calcium alginate/gelatin microcapsules. Cells were alive throughout the encapsulation procedure, and were recovered by a mechanical rupture of the microcapsules. After 7 days, fractured microcapsules led cells to migrate gradually out
