Behavioral and Biological Factors Related to HIV Transmission among Female Sex Workers in Ethiopia

Due to legal, cultural, and social factors, female sex workers (FSWs) experience anelevated level of violence, heavy alcohol consumption, and sexual abuse. Theseindividual and societal factors create a web of vulnerabilities that facilitate thespread of HIV within this population group. Moreover, stigma and discriminationare common among HIV-positive FSWs, contributing to poor HIV treatmentadheren

Hyperbranched Polymers in Cationic Photopolymerization of Epoxy Systems

Mixtures of epoxy resins in the presence of epoxy hyperbranched polymers (HBP), in the range of 5-15 wt%, were investigated in the cationic photocuring process. No significant differences in rate of polymerization or final epoxy groups conversion were observed. At low concentration, HBP acts as plasticizer and causes a decrease of the glass transition temperature of the epoxy matrix and of the E'

Process for production of an oxetane

A process for production of an oxetane, which process comprises subjecting an alcohol having two or more hydroxyl groups to reaction with a carbamide at a molar ratio employing 1-2 moles of said carbamide on 1-2 moles of said alcohol. The alcohols preferably have at least one 1,3-diol grouping. The reaction is carried out in the presence of at least one catalyst promoting and/or initiating transca

A formaldehyde and formate reduced polyol process

Formaldehyde and formate reduced process for preparation of a di, tri or polyalcohol from formaldehyde and a second aldehyde in the presence of an alkaline catalyst. The process comprises an aldol condensation yielding a methylolaldehyde and a subsequent crossed Cannizzaro reaction yielding said di, tri or polyalcohol and formate. The Cannizzaro reaction comprises reacting said methylolaldehyde wi

Thickness and composition of native oxides and near-surface regions of Ni superalloys

The surface chemistry and thickness of the native oxide, hydroxide, and modified sub-surface layer of three Ni superalloys (alloy 59, 625, and 718) were determined by synchrotron X-ray Photoelectron Spectroscopy (XPS) and X-ray Reflectivity (XRR). Taking advantage of the synchrotron radiation techniques, a procedure for normalizing the photoelectron intensity was employed, which allowed for accura

Implementing an intermittent spin-coating strategy to enable bottom-up crystallization in layered halide perovskites

Two-dimensional halide perovskites (2D PVSKs) have drawn tremendous attentions owing to their outstanding ambient stability. However, the random orientation of layered crystals severely impedes the out-of-plane carrier transport and limits the solar cell performance. An in-depth understanding coupled with an effective control of the crystallization in 2D PVSKs is the crux for highly efficient and

Readout of an antiferromagnetic spintronics system by strong exchange coupling of Mn2Au and Permalloy

In antiferromagnetic spintronics, the read-out of the staggered magnetization or Néel vector is the key obstacle to harnessing the ultra-fast dynamics and stability of antiferromagnets for novel devices. Here, we demonstrate strong exchange coupling of Mn2Au, a unique metallic antiferromagnet that exhibits Néel spin-orbit torques, with thin ferromagnetic Permalloy layers. This allows us to benefit

Improved temporal contrast of streak camera measurements with periodic shadowing

Periodic shadowing, a concept used in spectroscopy for stray light reduction, has been implemented to improve the temporal contrast of streak camera imaging. The capabilities of this technique are first proven by imaging elastically scattered picosecond laser pulses and are further applied to fluorescence lifetime imaging, where more accurate descriptions of fluorescence decay curves were observed

Efficacy and safety of pelvic organ prolapse surgery with porcine small intestinal submucosa graft implantation

Objective: The ideal implant material for the surgical repair of pelvic organ prolapse in women is yet to be found. This retrospective study aims to evaluate a porcine small intestinal submucosa (SIS) graft (Surgisis™). Study design: We reviewed the medical records of women that were operated upon for pelvic organ prolapse using implantation of SIS graft and we examined the short-term complication

The PROCEM study protocol : Added value of preoperative contrast-enhanced mammography in staging of malignant breast lesions - a prospective randomized multicenter study

Background: Correct preoperative estimation of the malignant extent is crucial for optimal planning of breast cancer surgery. The sensitivity of mammography is lower in dense breasts, and additional imaging techniques are sometimes warranted. Contrast-enhanced mammography (CEM) has shown similar sensitivity and in some cases better specificity, than magnetic resonance imaging (MRI) in small, obser

Types of second primary cancer influence overall survival in cutaneous melanoma

Background: Favorable survival in malignant cutaneous melanoma (melanoma) has increased the likelihood of second primary cancer (SPC). We assess the influence of patient characteristics at diagnosis of first melanoma and the type of SPC (second melanoma and other SPC) on overall survival. Methods: We used the Swedish Cancer Registry data to assess overall survival in melanoma for the period 1990 t

Fears of compassion and happiness in relation to alexithymia, mindfulness, and self-criticism

Background. There is increasing research to suggest that fears of, and resistances to, affiliative and positive emotions are linked to self-criticism and a range of psychopathologies. It is unclear how these fears and resistances are linked to each other and how these in turn are linked to psychological processes, such as abilities to be mindful and recognize and describe emotions. Objectives. Thi

An exploration of competitiveness and caring in relation to psychopathology

Objectives. Social mentality theory outlines how specialist systems have evolved to facilitate different types of social behaviour such as caring for offspring, forming alliances, and competing for resources. This research explored how different types of self-experience are linked to the different social mentalities of competitive social ranking (focusing on gaining and defending one's social posi

Dynamics of IgG-avidity and antibody levels after Covid-19

Background: A potentially important aspect of the humoral immune response to Covid-19 is avidity, the overall binding strength between antibody and antigen. As low avidity is associated with a risk of re- infection in several viral infections, avidity might be of value to predict risk for reinfection with covid-19. Objectives: The purpose of this study was to describe the maturation of IgG avidity

Managing multiple medications and their packaging for older people in home care nursing : An interview study

Home care nurses assist older people in their daily living and well-being, including medication management. Medication management can be challenging for older people with functional constraints and several chronic conditions. This paper presents how home care nurses manage medications and their packaging for older people at their homes. This study followed an explorative qualitative research desig

Assessing the outcome of rehabilitation after hip fracture with a wearable device—a study protocol for a randomized control trial in community healthcare

Background: The increase of the aging population is a challenge to society, as age is related to dependence. Injuries such as hip fractures cause morbidity, loss of independent life, and mortal-ity. The purpose of this protocol is to describe a randomized control trial, with three intervention arms, aiming at investigating if there are any differences in outcomes after hip fracture between differe

X-ray and neutron μCT of biomedical samples: from image acquisition to quantification

Even though the validity of x-ray computed tomography in the analysis of biomedical samples is nowadays undisputed, the more recent imaging techniques and more advanced instruments (such as synchrotrons) are still relatively unknown to many medical doctors that could benefit from them.The doctoral work presented in this thesis joins a collective effort from the imaging community to demonstrate pot
