In this study, a synthesis process based on the microemulsion method (ME) was developed with the aim to produce controlled-size starch nanoparticles (SNPs). Several formulations were tested for the preparation of the W/O microemulsions varying the organic/aqueous phase ratios and co-stabilizers concentrations. SNPs were characterized in terms of size, morphology, monodispersity and crystallinity.
Two-dimensional femtosecond broadband electronic spectroscopy was used to simultaneously probe parallel pathways of energy transfer in the major light harvesting complex of Photosystem II from plants. Sub-100 femtosecond relaxation between delocalized excitonic states on highly coupled clusters of chlorophylls and several hundred femtosecond to picosecond components of relaxation between clusters
This study explores systems for recognizing and rewarding teaching excellence in higher education, where engagement in the Scholarship of Teaching and Learning (SoTL) is considered an important merit. Nearly a decade ago, Fanghanel et al. (2016) identified the underutilized potential of teaching recognition as an institutional tool. More recently, Graham (2025) has documented a transformation in u
This study examines how public transport passengers experience and use travel time and under what conditions they are particularly concerned about shorter travel time. Using a survey of Swedish public transport users and a follow-up focus group, we compare current patterns with a similar 2009 study. Findings indicate a slight decline in perceived value of travel time, coinciding with a marked redu
Semiconductor nanowires provide a versatile platform for fluorescence-based detection enabled by their high refractive index and waveguiding properties, which amplify excitation and emission from surface-bound fluorophores. Together with their large surface-to-volume ratio, these features enable enhanced and even single-molecule sensitivity.This thesis explores the use of gallium phosphide (GaP) a
Rapporten sammanfattar fjärilsinventeringar utförda 2024 inom Biogeografisk uppföljning som drivs av Naturvårdsverket. I fjällområdet inventerades totalt 35 ytor. Sammanlagt noterades 33 högnordiska blåvingar på 11 av 16 inventerade ytor, 36 dvärgpärlemorfjärilar på 12 av 18 ytor och 13 fjällsilversmygare på 4 inventerade ytor. Svartfläckig blåvinge observerades på 26 av 49 inventerade lokaler. To
Preclinical transplantations using human neuroepithelial stem (NES) cells in spinal cord injury models have exhibited promising results and demonstrated cell integration and functional improvement in transplanted animals. Previous studies have relied on the generation of research grade cell lines in continuous culture. Using fresh cells presents logistic hurdles for clinical transition regarding t
Popular Abstract in Swedish En vän till mig berättade hur hon hade köpt en färgglad t-shirt vid en resa till Indien. Första gången hon hade den på sig började det att ösregna och ett par minuter senare fanns det snopet nog mer färg i de kringliggande vattenpölarna än i tyget. Lyckligtvis har de flesta färger idag bättre kvalitet än så. De färger som används inom textilindustrin är utvecklade för aConsiderable amounts of water and chemicals are used in the textile industry, and the presence of dyes in the wastewater is a problem of environmental concern. Synthetic dyes are designed to resist light, water and chemicals to improve the quality of the textiles; however, these properties also contribute to their persistence in the environment. The existence of wastewater treatment plants in conn
This paper presents a new Hardware (HW) im- plementation proposal for Discrete Fourier Transform (DFT) based channel estimators. The presented algorithm uses the high time correlation property of the channel estimates to reduce the complexity and the power consumption by utilizing a lower number of bits for the FFT in the channel estimator, compared to a traditional approach. The idea is that the
By the use of wavelength-modulation diode laser spectroscopy, water vapor and oxygen are detected in scattering media nonintrusively, at 980 nm and 760 nm, respectively. The technique demonstrated is based on the fact that free gases have extremely sharp absorption structures in comparison with the broad features of bulk material. Water vapor and oxygen measurements have been performed during the
Popular Abstract in Swedish Ekonomistyrsystemens utformning och roll är sedan 1980-talet föremål för stor uppmärksamhet mot bakgrund av pågående förändringar i företagens tillverknings- och marknadsmiljö. En grundläggande frågeställning som behandlas i boken är vilken påverkan företagens situation har på ekonomistyrsystemets utformning och om olika ekonomistyrsystem är mer ändamålsenliga än andra The focus of the thesis is the situation of and the management control systems in middle-sized, manufacturing companies. We have examined the relevance of different types of management control systems for different situations and formulated taxonomies of the contingency factors environment, production situation and business strategy. We found two types of situation. The first type, the interactive
This thesis describes inter and intramolecular dynamics in porphyrin molecules. To create a basis for understanding the energy and electron transfer processes in photosynthesis, the ultrafast dynamics of monomeric chlorophyll a, chlorophyll b and bacteriochlorophyll a were studied with ultrashort laser pulses. The transient absorption spectra of all three molecules were found to have pronounced co
Despite the importance of canon law in the life of the Eastern Orthodox Churches, there has not been a study of the ecclesiology of the canons regulating marriage. Marriage is an object of right regulated both by civil law and the canon law of the Eastern Orthodox Church. Marriage as an object of right is at the intersection of two legal orders - the ecclesial and the civil. The canonical regulati
This paper reports on the challenges computer forensic investigators face in relation to collaborative decision making, communication and coordination. The opportunities, operational environment and modus operandi of a cyber criminal are considered and used to develop the requirements in terms of both skill sets and procedural support a forensics investigator should have in order to respond to the
In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. These include, for instance, a high number of correlated measurement variables, non-stationarities, nonlinearities and multiscale process b
Energy consumption reduction is today an important design issue for all kinds of digital systems. Offering both flexibility and efficient energy management, variable speed processor architectures are prefered for low energy consumption even in hard real-time systems. For this type of systems, the main approach consists in trading speed for lower energy while meeting all deadlines. For tasks with v
