Differential scanning calorimetry (DSc) and dynamic light scattering (DLS) were used to obtain the gel to liquid-crystalline phase transition temperature (T-m) and the apparent hydrodynamic radius (R-h) of spontaneously formed cationic vesicles of dialkyldimethylammonium bromide salts (CnH2n+1)(2)(CH3)(2)N+center dot Br-, with varying chain lengths. The preparation of cationic vesicles from aqueou

The application of time-resolved fluorescence methods to study the aggregation behavior in aqueous solution of anionic surfactant sodium dodecyl sulphate (SDS) in presence of trivalent counterions (Al3+) was investigated. Addition of small amounts of aluminum salt to dilute micellar solutions (< 10 wt.% SDS) resulted in isotropic fluid solutions, but for a molar ratio [SDS]/[Al(NO3)(3)] lower than

Importance: Preterm birth has been associated with increased risk of heart failure (HF) early in life, but its association with new-onset HF in adulthood appears to be unknown. Objective: To determine whether preterm birth is associated with increased risk of HF from childhood into mid-adulthood in a large population-based cohort. Design, Setting, and Participants: This national cohort study was c

Rationale: Coronavirus disease (COVID-19) is an ongoing pandemic, in which obesity, hypertension, and diabetes have been linked to poor outcomes. Obstructive sleep apnea (OSA) is associated with these conditions and may influence the prognosis of adults with COVID-19. Objectives: To determine the effect of OSA on clinical outcomes in patients with COVID-19. Methods: The current prospective observa

In this study, we investigated the regional contributions of carbon dioxide (CO2) at the location of the high Alpine observatory Jungfraujoch (JFJ, Switzerland, 3580ĝ€¯mĝ€¯a.s.l.). To this purpose, we combined receptor-oriented atmospheric transport simulations for CO2 concentration in the period 2009-2017 with stable carbon isotope (δ13C-CO2) information. We applied two Lagrangian particle disper

The stability of proteins is an essential property that has several biological implications. Knowledge about protein stability is important in many ways, ranging from protein purification and structure determination to stability in cells and biotechnological applications. Experimental determination of thermal stabilities has been tedious and available data have been limited. The introduction of li

From liquefied human seminal plasma, we purified the predominant basic protein which appears following liquefaction of coagulated semen. The protein was purified in the presence of di-isopropylfluorophosphate to retard its degradation. Heparin-Sepharose® chromatography was followed by gel filtration (Biogel® P 60) and by fast performance liquid chromatography on a reversed phase column (C8). The b

With the full-scale colonization of Hokkaido, home to the indigenous Ainu people, by the Japanese Meiji government (1868-1912), unprecedented ethnographic opportunities emerged for Western scientists and adventure-seekers. Literally dozens of such individuals “discovered” information about the Ainu and their homeland during this period, introducing European and American audiences to the subject th

Corrosion in leak-tight plate structures, such as the containment liner in Nuclear Power Plants (NPPs), is detrimental to their operational state. To tackle this issue, the present work aims to assess the feasibility of using nonlinear ultrasound to detect corrosion. The corrosion product of main concern in the present study contains several microscopic and macroscopic cracks and delaminations. Th

In one way or another, everyone is a pedestrian. The planning for walkable cities has received more and more attention over the years. Researchers in the fields of transportation, the health sciences, urban design, and environmental psychology have all contributed to the walkability research by focusing on different aspects of walking. Walkability can be defined as factors related to the planning-

This essay conducts a semiotic analysis of four Walt Disney Pictures films, two from the 1990s and two from the past decade. The films were selected based on their release periods and shared narratives. The first two films analyzed are Vaiana from 2016 and Pocahontas from 1995, chosen for their focus on independent female protagonists. The other two films, En annorlunda värld from 2022 and Lejonku

Strålterapi är en vanligt förekommande behandling som ges till hälften av cancerpatienterna i landet. I fallet för prostatacancer, som utgör den vanligaste diagnosen, beror ofta cancerrelaterade dödsfall på återkomst av sjukdomen efter genomförd behandling. Vår hypotes är att detta kan minskas genom att identifiera strålrestistenta volymer i prostatan och öka stråldosen till dessa. Tyvärr finns deRadiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. These regions may be identified by hypoxia, given that radiobiological research has demonstrated a significant correlation between oxygen leve

The majority of the coastal area of Scania is highly susceptible to sediment transportation. Due to various influences which are both human induced and natural, the morphology of coastal dunes often alters. Therefore, it is important to assess these changes, especially after major cyclonic storms such as the storm Babet in order to get a comprehensive understanding of the aftermath. The purpose of

Studien undersöker på vilket sätt pedagoger och barn i förskolan kommunicerar kring musik. Syftet med undersökningen är att ta reda på vilka ord och begrepp som används i musikarbetet på förskolan och primärt i sångsamlingen och hur sångsamlingen organiseras. Genomförandet av studien utgår från två olika sätt att samla in data, observationer och kvalitativa intervjuer.
