Development of a Cost-Effective Miniaturized Microscope for Incubator Cell Culture Monitoring / Utveckling av ett kostnadseffektivt miniatyrmikroskop för övervakning av cellodlingar i inkubator

Nissolle, David January 2024 (has links)
A key component of biological research is cell culture technology, which allows researchersto examine the behavior and functionality of cells in controlled environments. Conventionalcell culture monitoring frequently necessitates taking the cultures out of their incubators tomake observations under a microscope. This exposes them to pollutants and changes in thesurrounding environment and may jeopardize the integrity of the experiment.This thesis presents the development of a cost-effective, miniaturized microscope designedfor imaging of cell cultures directly within incubators. By integrating simple, inexpensiveglass lenses and 3D-printed components and focusing on the ESP32-CAM module for digitalimaging, the project explores various optical setups to optimize image quality while minimizingdisruption to cell environments.Central to the research was the identification and testing of diverse optical configurations todetermine the most effective arrangement for both brightfield and fluorescence microscopy.The design features a baseplate for stability, a filter plate for fluorescence imaging, and afocus adjustment mechanism using magnets. Iterative enhancements led to a side illuminationtechnique using an economical LED, removing the need for a beamsplitter and simplifying theoptical path.The final microscope demonstrated successful brightfield imaging and weak fluorescenceimaging of Madin-Darby Canine Kidney (MDCK) II cell cultures marked with Green FluorescentProtein (GFP), using a magnification ratio of 2.5:1 through an infinity-corrected optical system.The findings illustrate the potential of developing an economical, functional microscope thatcan be readily replicated and scaled for use in cell culture technology. / En central del av biologisk forsking är användningen av cellkulturer, vilket tillåter forskare attutforska beeendet och funktionerna av celler i kontrollerade miljöer. Konventionell bevakning avcellkulturer kräver ofta att de tas ut från deras inkubatorer för att observeras under ett mikroskop.Detta kan utsätta dem för föroreningar och förändringar i omgivningen vilket kan äventyra helaexperimentet.Det här examensarbetet beskriver utvecklingen av ett kostnadseffektivt, miniatyriserat mikroskopanpassat för att avbilda cellkulturer inuti inkubatorer. Genom att integrera enkla, billigaglaslinser och 3D-printade komponenter, samt ESP32-CAM modulen för bildtagning, utforskardetta arbete olika optiska system för att optimera bildkvalitet och minimera störningar i cellernasmiljö.En väsentlig del av forskningen involverade identifiering och testning av olika optiska konfigurationerför att bestämma det mest effektiva arrangemanget för både brightfield- och fluorescensmikroskopi.Designen inkluderar en basplatta för stabilitet, en filterplatta för fluorescensavbildning ochen fokusjustering som utnyttjar magneter. Iterativa förbättringar ledde till utvecklingen av enbelysningsteknik med en billig LED, vilket tog bort behovet av en stråldelare och förenkladeden optiska banan.Det slutgiltiga mikroskopet uppvisade framgångsrik avbildning med brightfield och begränsadavbildning med fluorescens av MDCK II cellkulturer märkta med GFP. En förstoringsfaktor2.5:1 användes genom ett oändlighetskorrigerat optiskt system. Resultaten demonstrerar potentialenav att utveckla ett ekonomiskt och funktionellt mikroskop som kan replikeras för användninginom cellkulturforskning.

Francisco Jesus de Sousa 23 April 2010 (has links)
Os elevados índices de desperdícios na construção civil no Brasil reduzem significativamente as margens de lucro dos empreendedores. O superdimensionamento dos sistemas, paradas e retrabalhos por interferências entre projetos, informações faltando ou incorretas, empregos de materiais não padronizados e maior uso de mão-de-obra pela falta de construtibilidade são fatores ligados ao custo do desperdício originado pela falta de racionalização e coordenação do projeto. Neste contexto, o projeto apresenta-se como instrumento fundamental, devido à grande necessidade no setor da construção civil de aperfeiçoar a elaboração de projetos para otimizar e agregar valor ao empreendimento. Esta pesquisa tem como principal objetivo estudar e diagnosticar o processo de desenvolvimento e compatibilização de projetos em edifícios de múltiplos andares no pólo Petrolina-PE e Juazeiro-BA. O autor lança mão do uso da pesquisa qualitativa através da pesquisa de campo e a análise das incompatibilidades de projeto através de estudo de caso. A pesquisa qualitativa visa identificar os procedimentos empregados no desenvolvimento de projetos, a conformidade da representação gráfica, compatibilização de projetos, tecnologias CAD e tecnologia da informação. As análises do estudo de caso são realizadas através dos projetos arquitetônicos e complementares, visando à conformidade, padronização e compatibilidade dos elementos construtivos em edifícios de múltiplos andares. As conclusões apresentadas neste trabalho mostram um diagnóstico sobre o processo de desenvolvimento e compatibilização de projetos em edifícios de múltiplos andares, promovendo uma reflexão sobre uma série de questões relevantes com ênfase na diminuição do desperdício na construção civil e uma avaliação que possibilitou a revelação de empecilhos endógenos e exógenos no processo de compatibilização de projeto / The high levels of waste in the construction industry in Brazil reduce significantly the profit margins of entrepreneurs. The overestimation of the systems, stops and rework due to interferences between projects, missing or incorrect information, employment of non-standard materials and greater use of skilled manpower for the lack of constructability are factors related to the cost of waste caused by a lack or rationalization and project coordination. In this context, the project presents itself as essential, due to the great need in the construction industry to improve project design to optimize and add values to the enterprise. This research has as main objective to study and diagnose the process of development and compatibility of project in multi-floors building in the Petrolina-PE e Juazeiro-BA.

Počítačová podpora projektování datových rozvodů - projektová laboratoř / Computer support for data distribution design - design laboratory

Benešová, Lucie January 2010 (has links)
This thesis is concerned with data wiring infractructure. In the theoretical part the basic technology of the LAN networks is described as well as its parts, such as HUB and switch. Various types of transfer paths used in data wiring are briefly mentioned. They included coaxial cable, which were then replaced by shielded twisted pair and in future the fibre optics cables will be used instead. The shielded twisted pair operates on structured cabelling, which is guided by central principles in designing, which then can guarantee 15 years of good service. The most used cables 5e and 6 are described. The next chapter describes the endings of cables and connectors as well as the principles of patch pannels and patch cables. The following parts focus on the fibre optics networks, because they are the networks of the future. The types of fibre optics cables are described together with networks standards, the minimal fibre radius and innovations such as WDM or micropipes. There is also a resume of the ČSN norms, which are important for this thesis, concerning issues of the ways how to lay cables, placing of the communications etc. In the practical part, the various softwares for designing data wiring infractructure are studied and compared. As the most convinient for student proposals the AutoCAD Electrical 2011 has been chosen. This design software is studied from the point of view of its user interface and basic rules of behaviour. The functions of the menus and pripary settings are described. In the last part of the thesis the lesson is provided. The lesson should give students basic information and opportunity to design a basic data wiring infrastructure for a building.

Språkförskolan : En jämförelse mellan CAV- och VAV-system / Språkförskolan : A comparison between CAV and VAV systems

Lundberg, Mattias January 2019 (has links)
I denna rapport undersöks lönsamheten och energibesparingen av att byta ut befintligt CAV-system mot ett VAV-system i Språkförskolan som är belägen i Umeå på Marielund/Olofsdal området. Projektet utförs i samarbete med Tyréns i Umeå som är ett konsultföretag och ett av de ledande företagen inom samhällsbyggnad i Sverige.   Med hjälp av IDA ICE, som är ett energiberäkningsprogram, kunde en modell av förskolan byggas i 3D utifrån ritningar och inställningar såsom, antal personer, belysning, ventilationssystem och luftflöden, inomhustemperatur och så vidare, justeras för att vara så lik den verkliga byggnaden som möjligt. När alla värden var satta gjordes en energisimulering i programmet som ger mängder av värden som till exempel årlig energiförbrukning för olika system i byggnaden och värmeförluster genom byggnadens klimatskal. Filen duplicerades och CAV-systemet byttes ut mot ett VAV-system och ytterligare en simulering gjordes. Utifrån simuleringsresultaten jämfördes energiförbrukning för värmesystemet och fläktarna i de båda fallen.   I AutoCAD ritades en ventilationslösning med VAV-systemet i en avdelning av förskolan, med tillhörande VAV-spjäll som automatiskt justerar luftflödet efter den uppmätta belastningen i rummet. CAV-systemet justerar inte luftflödet utan går på max dimensionerat flöde hela tiden vilket inte är energieffektivt i rum med varierande belastning (människor).   Resultaten från simuleringarna visade att med styrd ventilation sjönk den totala årliga energiförbrukningen med 20 953 kWh vilket är en procentuell sänkning på 26%. Av denna energibesparingen stod värmesystemet för 67% och fläktarna för 33%. Investeringskostnaden för att installera VAV-spjäll i byggnaden är 192 000 SEK och utifrån den årliga besparingen hamnar återbetalningstiden på 19,7 år. Med en livslängd på 25–30 år anses en investering av VAV-systemet vara lönsam. / This report examines the profitability and energy-saving potential of replacing the existing CAV system with a VAV system in Språkförskolan, which is located in Umeå in the Marielund/Olofsdal area. The project is carried out in collaboration with Tyréns in Umeå, which is a consulting company and one of the leading companies in urban management in Sweden.   With the help of IDA ICE, which is an energy calculation program, a model of the preschool could be built in 3D based on floor plan drawings and settings such as the number of people, lighting, ventilation systems and air flows, indoor temperature and so on adjusted so as to be as similar to the actual building as possible. When all values ​​were set, an energy simulation was made in the program, which gave a lot of values ​​such as annual energy consumption for different systems in the building and heat losses through the building envelope. The file was duplicated, and the CAV system was replaced by a VAV system and another simulation was started. Based on the simulation results, energy consumption for the heating system and the fans was compared in both cases.   In AutoCAD, a ventilation solution was designed with the VAV system in one department of the preschool, with associated VAV dampers that automatically adjust the airflow according to the measured load in the room. The CAV system does not adjust the airflow but goes to the maximum dimensioned flow all the time which is not energy efficient in rooms with varying loads (people).   The results from the simulations showed that with variable ventilation, the total annual energy consumption decreased by 20 953 kWh, which is a reduction of 26%. Of this energy saving, the heating system accounted for 67% and the fans for 33%. The investment cost for installing VAV dampers in the building is SEK 192,000, and based on the annual savings the payback time was calculated to 19,7 years. With a lifetime of 25-30 years, an investment of the VAV system is considered to be profitable.
