Abstract:
Kefir susu kambing dengan penambahan seduhan kopi robusta (SKR) dimungkinkan dapat meningkatkan kualitas fungsional, karena kandungan antioksidan yang dimilikinya. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan SKR pada kefir susu kambing dan menentukan level persentase pemberian SKR yang maksimal. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 5 ualangan. Level penambahan SKR pada pembuatan kefir sebanyak 0; 5; 10; 15 dan 20 %. Parameter yang dianalisis meliputi pH diukur menggunakan pH meter, kadarpolifenol total menggunakan reagen Folin-Ciocalceu, dan aktivitas antioksdian ditetentukan dengan metode DPPH. Data yang diperoleh dianalisis menggunakan uji ANOVA, dan jika berpengaruh nyata atau siginifikan dilanjut menggunakan uji beda Tukey. Hasil penelitian menunjukan bahwa penambahan SKR terhadap nilai pH sangat berpengaruh nyata (P<0.05),kadarpolifenol total dan aktivitas antioksidan mengalami peningktan dibandingkan perlakuan P0 atau kontrol. Semakin tinggi penambahan SKR dalam pembuatan kefir maka semakin tinggi pula nilai pH yang dihasilkan. Penambahan SKR sebanyak 20% menghasilkan kefir dengan kadar pH 4.35, nilai pH ini masih masuk standar pH susu fermentasi untuk susu fermentasi. Kadar polifenol total pada penelitian ini semakin meningkat dengan semakin banyaknya penambahan SKR. Penambahan SKR sebanyak 20% menghasilkan kadar polifenol total sebesar 684.4686 mg/L lebih tinggi 70% dibandingkan control. Sampel kefir yang diperkaya 20% SKR menunjukan nilai aktivitas antioksdian paling tinggi DPPH IC50 sebesar 554.3444. Kesimpulan penelitian ini bahwa penambahan SKR efektif meningkatkan aktivitas antioksdian, kadar fenolat total, dan pH kefir sesuai standar susu fermentasi.

Abstract:
Abstract. The periodicity of Saturn kilometric radiation (SKR) varies with time, and its two periods during the first 5 years of the Cassini mission have been attributed to SKR from the northern and southern hemisphere. After Saturn equinox in August 2009, there were long intervals of time (March 2010 to February 2011 and September 2011 to June 2012) with similar northern and southern SKR periods and locked SKR phases. However, from March to August 2011 the SKR periods were split up again, and the phases were unlocked. In this time interval, the southern SKR period slowed down by ~ 0.5% on average, and there was a large jump back to a faster period in August 2011. The northern SKR period speeded up and coalesced again with the southern period in September 2011. We argue that this unusual behavior could be related to the so-called Great White Spot (GWS), a giant thunderstorm that raged in Saturn's atmosphere around that time. For several months in 2011, the visible head of the GWS had the same period of ~ 10.69 h as the main southern SKR modulation signal. The GWS was most likely a source of intense gravity waves that may have caused a global change in Saturn's thermospheric winds via energy and momentum deposition. This would support the theory that Saturn's magnetospheric periodicities are driven by the upper atmosphere. Since the GWS with simultaneous SKR periodicity measurements have only been made once, it is difficult to prove a physical connection between these two phenomena, but we provide plausible mechanisms by which the GWS might modify the SKR periods.

Abstract:
Introduction. The skin resistivity (SkR) measurement is commonly recommended for acupoints measurement, but for trigger points (TrPs) only one study is available. The purpose of the study was to evaluate SkR for latent TrPs compared to non-TrPs and the surrounding tissue.Material and Methods. Forty-two healthy volunteers with unilateral latent upper trapezius TrPs (12 men, 30 women) aged 21–23 (mean age: 22.1 ± 0.6 y) participated in the study. Keithley electrometer 610B was used for measuring SkR (Ag/AgCl self-adhesive, disposable ground electrode: 30 mm diameter). SkR was measured for latent TrPs and compared to opposite non-TrPs sites and the surrounding tissue.Results. The SkR decrease of TrPs-positive sites as compared to TrPs-negative sites and the surrounding tissue was confirmed. However, no statistically significant difference in the SkR value occurred when all data were analyzed. The same was confirmed after gender division and for TrPs-positive subjects examined for referred pain and twitch response presence.Conclusion. SkR reactive changes at latent TrPs are possible but the results were not consistent with the previous study. Thus, caution in applying SkR to latent TrPs isolation is recommended and its clinical use should not be encouraged yet. Further studies, especially on active TrPs, are yet required.

Abstract:
Abstract. Voyager spacecraft measurements of Saturn kilometric radiation (SKR) identified two features of these radio emissions: that they pulse at a period close to the planetary rotation period, and that the emitted intensity is correlated with the solar wind dynamic pressure (Desch and Kaiser, 1981; Desch, 1982; Desch and Rucker, 1983). In this study the inter-relation between the intensity and the pulsing of the SKR is analysed using Cassini spacecraft measurements of the interplanetary medium and SKR over the interval encompassing Cassini's approach to Saturn, and the first extended orbit. Cassini Plasma Spectrometer ion data were only available for a subset of the dates of interest, so the interplanetary conditions were studied primarily using the near-continuously available magnetic field data, augmented by the ion moment data when available. Intense SKR bursts were identified when solar wind compressions arrived at Saturn. The intensity of subsequent emissions detected by Cassini during the compression intervals was variable, sometimes remaining intense for several planetary rotations, sometimes dimming and rarely disappearing. The timings of the initial intense SKR peaks were sometimes independent of the long-term pulsing behaviour identified in the SKR data. Overall, however, the pulsing of the SKR peaks during the disturbed intervals was not significantly altered relative to that during non-compression intervals.

Abstract:
Skyrin (SKR) is a plant bisanthraquinone secondary metabolite from the Hypericum genus with potential use in anticancer therapy. However, its effect and mechanism of action are still unknown. The negative effect of SKR on HCT 116 and HT-29 cancer cell lines in hypoxic and normoxic conditions was observed. HCT 116 cells were more responsive to SKR treatment as demonstrated by decreased metabolic activity, cellularity and accumulation of cells in the G1 phase. Moreover, an increasing number of apoptotic cells was observed after treatment with SKR. Based on the LC-MS comparative proteomic data from hypoxia and normoxia (data are available via ProteomeXchange with the identifier PXD019995), SKR significantly upregulated Death receptor 5 (DR5), which was confirmed by real-time qualitative PCR (RT-qPCR). Furthermore, multiple changes in the Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-activated cascade were observed. Moreover, the reversion of TRAIL resistance was observed in HCT 116, HT-29 and SW620 cell lines, even in hypoxia, which was linked to the upregulation of DR5. In conclusion, our results propose the use of SKR as a prospective anticancer drug, particularly as an adjuvant to TRAIL-targeting treatment to reverse TRAIL resistance in hypoxia.

Abstract:
Denna uppsats är en diskursanalys över Sveriges kvinno- och tjejjourers två riksförbunds (Roks och Unizon) konstruktion av mäns våld mot kvinnor som socialt problem. Syftet är att belysa hur riksförbunden bidrar till förståelsen av mäns våld mot kvinnor som socialt problem och hur riksförbunden bidrar till konstruktionen och beskrivningen av det sociala problemets orsaker och lösningar. Materialet består av pressmeddelanden från respektive förbund under perioden 2013–2015. Med socialkonstruktionismen som forskningsansats och Faircloughs kritiska diskursanalys som teori och metod har samtliga texter analyserats och sedan sammanfattats i en schemamodell skapad av Håkan Jönsson. Resultatet visar på fyra diskurser inom diskursordningen; två för förbunden gemensamma (strukturkritisk diskurs och diskursen om offentlig sektor som inkompetent samarbetspartner) samt två diskurser specifika för var sitt förbund (Roks professionaliseringskritiska diskurs och Unizons våldspreventiva lösningsorienterade diskurs). Uppsatsen avslutas med en diskussion kring vidare forskning utifrån frågorna hur sociala problem kan konstrueras och förstås med hjälp av civilsamhällets aktörers kommunikation utåt och i relation till resultatet hur civilsamhällets aktörers upplevelser kring samarbetet med offentlig sektor ser ut och kan tänkas förbättras.

Abstract:
In this study, religiosity in prison is investigated. What opportunities are there for those detained to practice their religion and how did their religiosity change after they were detained? Six interviews were conducted to gain a better perspective of religiosity in prison. The focus is on Correctional Institution in Kalmar, where surveys have been conducted over a longer period but also the monastery at the Correctional facility in Kumla is discussed. Most interviews were conducted in the prison of Kalmar, in a room where religious conversations are conducted. The inmates’ and the prison guard´s name have been changed to protect their identity. A common thread throughout the interviews is that the religious group often talks about much more than religion. Detainees also talk about their involvement in these talks as an opportunity of breaking the everyday routines that occur in prisons. This strengthens Peter Berger and Thomas Luckmann´s theory that religion is a group phenomenon created, among other things, to feel a social connectedness.

Abstract:
Klimatfrågan är idag en världsomfattande utmaning och därmed krävs ett omfattande arbete för att minska vår klimatpåverkan. Parallellt i samhället har det skett en stor utveckling inom digitalisering och ökad implementation av informationssystem. Tidigare forskning belyser att informationssystem besitter en stor potential för ett mer hållbart arbete där kommuner och regioner innehar en viktig roll i att miljöanpassa sina verksamheter. Green IS (Green Information Systems) och Environmental Management Systems (EMS) är två termer som vuxit fram inom IS-sektorn. Det innebär att implementera informationssystem som stödjer miljöarbete och hållbarhet samtidigt som effektivisering och kostnadsreducering eftersträvas. Syftet med denna studie har varit att undersöka hur kommuner och regioner i Småland använder sig av Green IS och EMS för ett mer hållbart klimatarbete. Studien ämnade att belysa vilken sorts system som används och huruvida det bidrog till ett minskat klimatavtryck. Kommuner och regioner är stora aktörer och det ses som viktigt att de ligger i framkant för en utveckling gentemot ett land utan fossila utsläpp. För att besvara studiens frågeställningar utfördes en kvalitativ små-N-studie på sex kommuner och regioner. Informanterna valdes ut strategiskt då de arbetade i olika roller på respektive miljöenhet. Insamling av empiriskt material utfördes genom semistrukturerade intervjuer för en djupare förståelse inom området. Vidare tillämpades en tematisk analys för att strukturera det empiriska resultatet. Strategiska teman valdes ut för att framhäva hur kommuner och regioner verkar i det generella miljöarbetet, hur de använder informationssystem och huruvida det har hjälpt till för organisationen. Resultatet från den här studien visade att kommuner och regioner använde en mängd system och digitala verktyg inom verksamheten som kan härledas till Green IS och EMS. Majoriteten av organisationerna hade någon form av mjukvara för att beräkna och rapportera klimatdata, samt möjlighet att visualisera denna data. I organisationernas klimatarbete användes det för att samla in statistik för utsläpp och samtidigt identifiera kritiska områden. Det mynnade ut i att åtgärder har kunnat implementerats i avsikt mot ett mer effektivt miljöarbete. Det empiriska resultatet tyder på att det inte finns några kvantitativa siffror på hur användningen av Green IS och EMS har påverkat organisationernas klimatavtryck. Det har istället varit till hands genom ett effektivare sätt att identifiera kritiska områden genom beräkning och visualisering av klimatdata, som sedan har agerat underlag för åtgärder. Följaktligen har Green IS och EMS implementerats på flera sätt i kommuner och regioner vilket lett till indirekta minskningar i dess utsläpp.<br>Nowadays, the climate issue is a worldwide challenge and, thus, extensive work from individual actors and organizations is required to reduce our climate impact. In parallel, there has been major development in digitization and implementation of information systems (IS). Previous research highlights that information systems have great potential for more sustainable work.  The Information Systems, which go under the collective names of Green IS and Environmental Management Systems (EMS), have been implemented in organizations to support environmental work and sustainability, while striving for efficiency and cost reduction.                Municipalities and regions are major organizational actors and it is important that they are at the forefront of a development towards a country without fossil emissions. Thus, the purpose of this bachelor thesis research has been to investigate how municipalities and regions in Småland use Green IS and EMS for sustainability and climate work. The research study explored which type of these information systems are used in municipalities and regions in Småland and whether their use has contributed to reduced climate footprint. For this, a small-N-approach was selected in six municipalities and regions. The informants were purposively chosen as they work in different roles at environmental units of municipalities and regions. For the collection of empirical research data, semi-structured interviews were conducted with the aforementioned informants to gain a deeper knowledge and understanding of the research topic. Furthermore, a thematic analysis was applied to present the research results and highlight how municipalities and regions operate regarding environmental work; how they use information systems for that purpose and whether this has helped the organization. The bachelor thesis research results show that municipalities and regions used a variety of Green IS, Environmental Management Systems and related digital tools.  Most of the organizations had some form of software and applications for calculating and reporting climate data, as well as the ability to visualize this data. Within the organization’s climate work, this was used to collect statistics for emissions and, at the same time, identify critical areas. This has resulted in measures being implemented in the pursuit of more efficient climate work. The research results indicate that there are no quantitative figures on how the use of Green IS and EMS has affected the organization’s climate footprint. Instead, it has provided a more efficient way to identify critical areas through calculation and visualization of climate data, which has been the basis for measurements. Concluding, Green IS and EMS were found to be implemented in several ways, indirectly reducing emission factors in the study’s surveyed municipalities and regions.

Abstract:
La plupart de variétés élites de blé tendre ne peuvent pas être croisées avec des espèces apparentées ce qui restreint considérablement la base génétique qui peut être utilisée pour l'introgression de nouveaux allèles dans les programmes de sélection. L'inhibition de l'hybridation entre le blé et les espèces apparentées (e.g. seigle, orge) est génétiquement contrôlée. Un certain nombre de QTLs ont été identifiés à ce jour, y compris les gènes Kr1 sur le chromosome 5BL et SKr, un QTL majeur identifié au laboratoire en 1998 sur le bras court du chromosome 5B, tous deux impliqués dans l'inhibition du croisement entre le blé tendre et le seigle. Dans cette étude, nous avons utilisé une population recombinante SSD provenant d'un croisement entre la variété Courtot non croisable et la lignée MP98 croisable pour caractériser l'effet majeur dominant de SKr. Le gène a ensuite été cartographié génétiquement sur la partie distale du chromosome 5BS à proximité du locus GSP (Grain Softness Protein) dont l'homéologue sur le chromosome 5D est impliqué dans la dureté du grain (locus Ha). Les relations de colinéarité avec l'orge et le riz ont été utilisées pour saturer la région de SKr par de nouveaux marqueurs et établir des relations orthologues avec une région de 54 kb sur le chromosome 12L de riz. Au total, 6 marqueurs moléculaires ont été cartographiés dans un intervalle génétique de 0,3 cM, et 400 kb de contigs physiques de BAC ont été établis des deux cotés du gène afin de jeter les bases du clonage positionnel de SKr. De nouvelles populations de grands effectifs ont été développées pour la localisation précise du gène SKr sur les cartes génétiques et physiques. 223 individus d'une population HIF (SSD254.14) ont été testés pour leur aptitude au croisement avec le seigle et génotypés avec les marqueurs proches du gène pour confirmer les données obtenues dans la population de départ. Les résultats montrent que SKr est localisé dans une région hautement recombinante et que les relations entre distances génétiques et distances physiques sont favorables aux dernières étapes de clonage positionnel du gène. Enfin, deux marqueurs SSR complètement liés au gène SKr ont été utilisés pour évaluer une collection de descendances de blé aptes au croisement avec le seigle originaires d'un programme de sélection de triticale primaire. Les résultats confirment l'effet majeur de SKr sur l'aptitude au croisement et l'utilité des deux marqueurs pour introgresser l'aptitude au croisement interspécifique dans des variétés élites de blé tendre.

Abstract:
We experimentally demonstrate a RF-assisted four-state continuous-variable quantum key distribution (CV-QKD) system in the presence of turbulence. The atmospheric turbulence channel is emulated by two spatial light modulators (SLMs) on which two randomly generated azimuthal phase patterns are recorded yielding Andrews' azimuthal phase spectrum. Frequency and phase locking are not required in our system thanks to the proposed digital phase noise cancellation (PNC) stage. Besides, the transmittance fluctuation can be monitored accurately by the DC level in this PNC stage, which is free of post-processing noise. The mean excess noise is measured to be 0.014, and the maximum secret key rate of >20Mbit/s can be obtained with the transmittance of 0.85, while employing the commercial PIN photodetectors.

Abstract:
Spent Fuel Repository for low and intermediate radioactive waste, SFR, is owned by SKB (Swedish Nuclear Fuel and Waste Management Co). The repository needs more monitoring of groundwater seepage and improvement of the monitoring methods. Seepage is currently managed by a system that collects the seepage in 2 levels before pumping it to the surface. The current method only allows for the continuous measurement of groundwater seepage in one location in the system. Seepage is measured once per year in different locations in the repository to monitor the amount of seepage in the different parts of the repository. The seepage is primarily caused by deformation zones in the vicinity of the facility. The suggested improvements to the measuring system are to increase the number of places that measure groundwater seepage and up dated the current system in order to increase the measuring accuracy.

Abstract:
Synthetic Aperture Radar (SAR) has proven a valuable tool in the monitoring of the Earth, either at a global or local scales. SAR is a coherent radar system able to image extended areas with high resolution, and finds applications in many areas such as forestry, agriculture, mining, structure inspection or security operations. Although space-borne SAR systems can image extended areas, their main limitation is the long revisit times, which are not suitable for applications where the target experiments rapid changes, in the scale of minutes to few days. GBSAR systems have proven useful to fill this revisit time gap by imaging relatively small areas continuously, with extensions usually smaller than a few square kilometers. Ground Based SAR (GBSAR) systems have been used extensively for the monitoring of slope instability, and are a common tool in the mining sector. The development of the GBSAR is relatively recent, and various developments have taken place since the 2000s, transitioning from the usage of Vector Network Analyzers (VNAs) to custom radar cores tailored for this application. This transition is accompanied by a reduction in cost, but at the same time is accompanied by a loss of operational flexibility. Specifically, most GBSAR sensors now operate at a single frequency, losing the value of the multi-band operation that VNAs provided. This work is motivated by the idea that it is worth to use the value of multi-frequency GBSAR measurements, while maintaining a limited system cost. In order to implement a GBSAR with these characteristics, it is realized that Software Defined Radio (SDR) devices are a good option for fast and flexible implementation of broadband transceivers. This thesis details the design and implementation process of an SDR-based Frequency Modulated Continuous Wave (FMCW) GBSAR system from the ground up, presenting the main issues related with the usage of the most common SDR analog architecture, the Zero-IF transceiver. The main problem is determined to be the behavior of spurs related to IQ imbalances of the analog transceiver with the FMCW demodulation process. Two effective techniques to overcome these issues, the Super Spatial Variant Apodization (SSVA) and the Short Time Fourier Transform (STFT) signal reconstruction techniques, are implemented and tested. The thesis also deals with the digital implementation of the signal generator and digital receiver, which are implemented on top of an RF Network-on-Chip (RFNoC) architecture in the SDR Field Programmable Gate Array (FPGA). Another important aspect of this work is the development of an radiofrequency front-end that extends the capabilities of the SDR, implementing filtering, amplification, leakage mitigation and up-conversion to X-band. Finally, a set of test campaigns is described, in which the operation of the system is verified and the value of multi-frequency GBSAR observations is shown.<br>El radar d'obertura sintètica (SAR) ha demostrat ser una eina valuosa en el monitoratge de la Terra, sigui a escala global o local. El SAR és un sistema de radar coherent capaç d’obtenir imatges de zones extenses amb alta resolució i té aplicacions en moltes àrees com la silvicultura, l’agricultura, la mineria, la inspecció d’estructures o les operacions de seguretat. Tot i que els sistemes SAR embarcats en plataformes orbitals poden obtenir imatges d'àrees extenses, la seva principal limitació és el temps de revisita, que no són adequats per a aplicacions on l'objectiu experimenta canvis ràpids, en una escala de minuts a pocs dies. Els sistemes GBSAR han demostrat ser útils per omplir aquesta bretxa de temps, obtenint imatges d'àrees relativament petites de manera contínua, amb extensions generalment inferiors a uns pocs quilòmetres quadrats. Els sistemes SAR terrestres (GBSAR) s’han utilitzat àmpliament per al control de la inestabilitat de talussos i esllavissades i són una eina comuna al sector miner. El desenvolupament del GBSAR és relativament recent i s’han produït diversos desenvolupaments des de la dècada de 2000, passant de l’ús d’analitzadors de xarxes vectorials (VNA) a nuclis de radar personalitzats i adaptats a aquesta aplicació. Aquesta transició s’acompanya d’una reducció del cost, però al mateix temps d’una pèrdua de flexibilitat operativa. Concretament, la majoria dels sensors GBSAR funcionen a una única freqüència, perdent el valor de l’operació en múltiples bandes que proporcionaven els VNA. Aquesta tesi està motivada per la idea de recuperar el valor de les mesures GBSAR multifreqüència, mantenint un cost del sistema limitat. Per tal d’implementar un GBSAR amb aquestes característiques, s’adona que els dispositius de ràdio definida per software (SDR) són una bona opció per a la implementació ràpida i flexible dels transceptors de banda ampla. Aquesta tesi detalla el procés de disseny i implementació d’un sistema GBSAR d’ona contínua modulada en freqüència (FMCW) basat en la tecnologia SDR, presentant els principals problemes relacionats amb l’ús de l’arquitectura analògica de SDR més comuna, el transceptor Zero-IF. Es determina que el problema principal és el comportament dels espuris relacionats amb el balanç de les cadenes de fase i quadratura del transceptor analògic amb el procés de desmodulació FMCW. S’implementen i comproven dues tècniques efectives per minimitzar aquests problemes basades en la reconstrucció de la senyal contaminada per espuris: la tècnica anomenada Super Spatial Variant Apodization (SSVA) i una tècnica basada en la transformada de Fourier amb finestra (STFT). La tesi també tracta la implementació digital del generador de senyal i del receptor digital, que s’implementen sobre una arquitectura RF Network-on-Chip (RFNoC). Un altre aspecte important d’aquesta tesi és el desenvolupament d’un front-end de radiofreqüència que amplia les capacitats de la SDR, implementant filtratge, amplificació, millora de l'aïllament entre transmissió i recepció i conversió a banda X. Finalment, es descriu un conjunt de campanyes de prova en què es verifica el funcionament del sistema i es mostra el valor de les observacions GBSAR multifreqüència.

Abstract:
Det nordiska samarbetet ska vara tillgängligt och inkluderande, och den politik som genereras ska vara relevant för alla nordbor oavsett funktionsförmåga. I den här rapporten presenteras hur arbetet går, och vad som händer område för område. Att integrera ett funktionshindersperspektiv handlar för Nordiska ministerrådet om att synlig- och tydliggöra situation och behov hos personer med funktionsnedsättning samt att främja inkludering genom universell utformning och tillgänglighet. Det kan gälla praktiska saker, så som att politiska möten ska vara tillgängliga och det ska gå att ta del av ministerrådets rapporter och hemsida även med digitala hjälpmedel. Det handlar också om att främja inkludering av personer med olika typer av funktionsnedsättning i den politik som utvecklas genom samarbetet. Målet är att alla relevanta politikområden, administration och institutioner inom det nordiska samarbetet ska ha ett integrerat funktionshindersperspektiv. I den här statusrapporten går vi igenom allt arbete som skett under 2021, område för område. De olika områdena blickar också framåt och ser vad nästa steg är för att blir ännu mer inkluderande och tillgängliga.
