Adaptació i canvi d'ús de la Farinera a hotel
Aquest treball consisteix a canviar l'ús i adaptar un edifici modernista a un hotel similar a tres estrelles a
partir d’una proposta i estudi de renovació interior. El punt de partida escollit és la fà brica de farina 'La
Farinera', construïda a finals del segle XIX a la ciutat de Vic i projectada per l'arquitecte Enric Sagnier.
Amb els anys, la seva funció ha anat canviant: des de fà brica d’embotits, de filatura, calçats i teixits fins
a fà brica de farina. El procés de transformació en hotel es va dur a terme a partir d'un anà lisi del seu
arquitecte i de les caracterÃstiques històriques i arquitectòniques de l'edifici.
Per començar a realitzar l'estudi es van cercar edificis modernistes a Vic que tinguessin algun tret
caracterÃstic per poder-los convertir en un hotel. Entre tots ells, la Casa d'Anita Colomer i la Farinera
van ser les opcions preferides per la seva estètica peculiar. Aquesta primera, però, es va descartar
perquè no tenia prou superfÃcie útil per ser un hotel.
Pel que fa a la metodologia, es va fer un estudi de la història de l'edifici, poc documentat, i una recerca
d'informació del seu arquitecte a partir dels llibres que existeixen de la seva biografia. A partir de
l'amidament in-situ de la Farinera, representada en diversos esbossos i croquis, juntament amb la
informació d'una reforma recent, es van poder realitzar els plà nols per convertir la fà brica La Farinera a
hotel. Un cop obtinguda tota aquesta informació i utilitzant la normativa del Codi Tècnic com a
referència, es va poder fer l’adaptació de l’edifici, digitalitzant i redistribuint l'espai amb l’AutoCad.
Paral·lelament es van anar aixecant seccions i façanes, aquestes últimes retocant-les amb l’Adobe
Illustrator. Finalment amb el Google Sketchup i el 3D Studio Max es van traçar les perspectives interiors
i exteriors, que ajuden a entendre molt millor el volum de l'edifici sencer.
El resultat del procés de renovació ha estat un hotel acollidor semblant a un hotel de tres estrelles amb
un disseny interior fidel al seu antic ús industrial i al seu estil arquitectònic, amb elements decoratius
propis del modernisme.
Com a conclusió penso que La Farinera convertida en hotel podria ser un benefici per a la ciutat de Vic,
millorant l’escassa oferta d’allotjament al centre de la ciutat i alhora preservant i posant a l’abast del
públic un edifici amb les arrels culturals i històriques del patrimoni vigatà .ENGLISH: This study is focused on the adaption of a Modernist building and its change of use to a three-star hotel
based on a building proposal and interior renovation. The chosen building was a flour mill, La Farinera,
built at the end of the 19th century in the city of Vic and designed by the architect Enric Sagnier. Over
the years the building has undergone several changes in use, cold meat processing, shoe, thread and
textile manufacturing and finally a flour mill. The transformation study of the building into a hotel was
carried out after an analysis of the building’s architect and the historical and architectural characteristics
of the building.
The study also emerged from a search of Modernist buildings in Vic with features that would be suitable
for hotel conversion. Among these buildings, Casa Anita Colomer and La Farinera seemed the best
options as a result of their special aesthetic qualities. The former, however, was discarded as a possible
hotel due to its lack of useful surface area.
As for the methodology, a study of the history of the building was made, although little had been
published about it, and the building’s architect was researched from books that exist about his life. By
taking in-situ measurements of La Farinera, which were then presented in different rough sketches and
drawings, as well as information from recent reforms, the plans could be drawn up to convert the flour
mill into a hotel. Once all this information was obtained, and using the regulations in the Spanish
Technical Building Code as a reference, the adaptation of the building was possible, digitalising and
redistributing spaces with AutoCAD. In parallel, sectors and façades were drawn up, the latter being
touched up with Adobe Illustrator. Finally, with Google Sketchup and 3D Studio Max the interior and
exterior perspectives of the building were traced which help to understand the volume of the whole
building much more clearly.
The result of this renovation proposal is a cosy hotel with similar to a three-star rating and an interior
design which is faithful to the building’s industrial origins and architectural style with decorative elements
characteristic of Modernism.
In conclusion La Farinera converted into a hotel could be of great benefit to the city of Vic, improving the
little tourist accommodation on offer in the city centre and simultaneously preserving and making
available to the public a building with strong cultural and historical roots in Vic’s heritage
Development of a methodology based on headspace-gas chromatography-ion mobility spectrometry for the rapid detection and determination of patin fish oil adulterated with palm oil
The present research intends to develop a new method based on headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) for the detection and determination of patin fish oil adulterated with different percentages of palm oil, because it is a cheaper vegetable oil. Five variables that affect headspace generation (incubation time and temperature, amount of sample, injection volume, and pre-heating time) have been optimized by means of a Box Behnken design in combination with Response Surface Methodology. Then, repeatability and intermediate precision have been studied where coefficients of variation lower than 10% were obtained. This new method has been applied to several samples of patin fish oil adulterated with palm oil at 20 different levels (5-50% palm oil content). The results have confirmed the suitability of the HS-GC-IMS for a rapid, easy, and reliable detection and discrimination of adulterated oil samples since a characteristic fingerprint that allows 100% successful discrimination between adulterated and unadulterated patin oil samples was achieved. Finally, a regression model has been developed to determine each sample's adulteration level with an error lower than 10% and a coefficient of determination greater than 0.95. (C) 2020 The Author(s).

Micro Ion Mobility Spectrometry for Gas-phase Detection
En un món ideal, podrÃem ser capaços de detectar rà pidament i classificar qualsevol tipus de substà ncia quÃmica i biològica que es trobés en baixes concentracions, utilitzant instruments petits i de fà cil ús. És en aquest escenari on va aparèixer l'espectrometria de mobilitat iònica (IMS). Es tracta d'una tècnica de mesura i anà lisi, on els analits ionitzats es separen per diferències de mobilitat sota la influència d’un camp elèctric en un flux de gas neutre o d'aire a pressió i temperatura ambient. Els avantatges de l'IMS inclouen instrumentació compacte i portà til, un temps de separació curt (escala de mili-segons), i uns lÃmits de detecció baixos, i permeten una à mplia gamma d'aplicacions. En aquest sentit, un esforç intens de recerca s'ha enfocat cap a la miniaturització dels dispositius d'IMS disponibles vers als micro- espectròmetres de mobilitat iònica de forma d’ona asimètrica i d’alt camp (FAIMS).
En aquesta tesi es presenten els primers desenvolupaments i contribucions tecnològiques als FAIMS en el IMB-CNM (CSIC). En particular, aquest treball està dedicat a la simulació, disseny, i fabricació d'un micro FAIMS planar (p-FAIMS) per a aplicacions de seguretat. El treball s'organitza en cinc capÃtols dividits en dues seccions.
La primera secció consta de tres capÃtols. El primer capÃtol és introductori i en el segon capÃtol s'introdueix al lector en l'actual estat de la tècnica de l'espectrometria de mobilitat iònica en general i en particular per als micro- espectròmetres de mobilitat iònica de forma d’ona asimètrica i d’alt camp. El tercer capÃtol descriu el modelatge d'un tipus de FAIMS planar per a diferents camps elèctrics i condicions de flux.
La segona part consta de dos capÃtols. El quart capÃtol presenta un resum dels diferents dissenys i materials considerats per a la implementació del p-FAIMS: estructures Vidre-Si-Vidre i PCB-PMMA-PCB, les tasques tecnològiques fetes per cada un i les estratègies de solució que hi han conduit. La fotoionització UV ha estat l'escollida com a mètode de ionització en tots els casos per raons de seguretat. També es presenta la caracterització amb toluè del nou prototip de p-FAIMS de baix cost fabricat a l'IMB-CNM. El cinquè capÃtol es presenta un resum de l'estudi de la viabilitat del monitoratge d'un fà rmac analgèsic (remifentanil) en l’alè de pacients sota anestèsia. Un espectròmetre de mobilitat iònica comercial s'utilitza per a aquesta aplicació mèdica en col·laboració amb el KIST-Europe i la Chirurgische Universitätsklinik d'Homburg (Alemanya).In an ideal world, we might be able to rapidly detect and classify any type of chemical and biological that is found in low concentrations, using instruments of small size and easy implementation. Is in that scenario where the Ion mobility spectrometry (IMS) appeared. It is a technique of measurement and analysis, where ionized analytes are separated by mobility differences under electric field in a flow of neutral gas or air at ambient pressure and temperature. The advantages of IMS include compactness and portability of instrumentation, short separation time (milliseconds scale), and low detection limits, and allow a wide range of applications. In this sense, an intense research effort has been focused towards miniaturization from the available IMS’s devices to the micro high-Field Asymmetric waveform Ion Mobility Spectrometers (FAIMS).
This thesis presents the first developments and technological contributions to the FAIMS at IMB-CNM (CSIC). Particularly, this work is dedicated to the simulation, design, and fabrication of a micro planar FAIMS (p-FAIMS) for security applications. The work is organized in five chapters divided in two sections.
The first section consists of three chapters. Chapter one is introductory, and on Chapter two introduces the lector to the actual state-of-the-art of the Ion Mobility Spectrometry in general and in particular for the micro high-Field Asymmetric waveform Ion Mobility Spectrometry. Chapter three described the modeling of a planar type of FAIMS for different electric fields and flow conditions.
The second section consists of two chapters. Chapter four provides a summary of the different designs and materials considered for the p-FAIMS implementation: Glass-Si-Glass and PCB-PMMA-PCB structures; the technological tasks done for each one and the solving strategies that have leaded to it. UV photoionization has been the chosen as ionization method for safety reasons in all cases. It also presents the characterization with toluene of the new low-cost p-FAIMS prototype fabricated in the IMB-CNM. Chapter five provides a summary of the feasibility study of an online-monitoring of an analgesic drug (remifentanil) in patients breath under anesthesia. A commercial Ion Mobility Spectrometer is used for this medical application in collaboration with the KIST-Europe and the Chirurgische Universitätsklinik from Homburg (Germany)

Chemical analysis of whale breath volatiles: a case study for non-invasive field health diagnostics of marine mammals.
Chemical Analysis of Whale Breath Volatiles: A Case Study for Non-Invasive Field Health Diagnostics of Marine Mammals
We explored the feasibility of collecting exhaled breath from a moribund gray whale (Eschrichtius robustus) for potential non-invasive health monitoring of marine mammals. Biogenic volatile organic compound (VOC) profiling is a relatively new field of research, in which the chemical composition of breath is used to non-invasively assess the health and physiological processes on-going within an animal or human. In this study, two telescopic sampling poles were designed and tested with the primary aim of collecting whale breath exhalations (WBEs). Once the WBEs were successfully collected, they were immediately transferred onto a stable matrix sorbent through a custom manifold system. A total of two large volume WBEs were successfully captured and pre-concentrated onto two Tenax®-TA traps (one exhalation per trap). The samples were then returned to the laboratory where they were analyzed using solid phase micro extraction (SPME) and gas chromatography/mass spectrometry (GC/MS). A total of 70 chemicals were identified (58 positively identified) in the whale breath samples. These chemicals were also matched against a database of VOCs found in humans, and 44% of chemicals found in the whale breath are also released by healthy humans. The exhaled gray whale breath showed a rich diversity of chemicals, indicating the analysis of whale breath exhalations is a promising new field of research
