The role of accelerator programmes on the capital structure of start-ups

Several factors affect the capital structure of start-ups. In this study, we compare the capital structure choices of accelerated and non-accelerated start-ups to evaluate the role of accelerated programmes on the capital structure decisions for startups. Using a comprehensive database provided by Emory University, we find that accelerated start-ups have higher external equity ratios than non-acce

Portuguese version of the PTSD Checklist-Military Version (PCL-M)-I : Confirmatory Factor Analysis and reliability

The PTSD Checklist-Military Version (PCL-M) is a brief self-report instrument widely used to assess Post-traumatic Stress Disorder (PTSD) symptomatology in war Veterans, according to DSM- IV. This study sought out to explore the factor structure and reliability of the Portuguese version of the PCL-M. A sample of 660 Portuguese Colonial War Veterans completed the PCL-M. Several Confirmatory Factor

Proportions of polyunsaturated fatty acids in umbilical cord blood at birth are related to atopic eczema development in the first year of life

Atopic eczema, the most common atopic disease in infants, may pave the way for sensitization and allergy later in childhood. Fatty acids have immune-regulating properties and may regulate skin permeability. Here we examine whether the proportions of fatty acids among the infant and maternal plasma phospholipids at birth were associated with maternal dietary intake during pregnancy and development

Surgery is underused in elderly patients with left-sided infective endocarditis : A nationwide registry study

BACKGROUND: Infective endocarditis is associated with higher mortality in elderly patients, but the role of surgery in this group has not been fully evaluated. The aim of this study was to assess outcomes of left-sided infective endocarditis in elderly patients and to determine the influence of surgery on mortality in the elderly. METHODS AND RESULTS: A nationwide retrospective study was performed

Use of bacterial strains antagonistic to Escherichia coli for biocontrol of spinach : A field trial

To counteract global food safety hazards related to raw consumption of ready-to-eat leafy vegetables, a method to improve bacterial status using antagonistic bacteria was studied under field conditions. This is the first study to identify potential Escherichia coli antagonists from the native microbiota on leafy green vegetables and evaluate their effect in an industrial field production setting.

Resilient cooling strategies : A critical review and qualitative assessment

The global effects of climate change will increase the frequency and intensity of extreme events such as heatwaves and power outages, which have consequences for buildings and their cooling systems. Buildings and their cooling systems should be designed and operated to be resilient under such events to protect occupants from potentially dangerous indoor thermal conditions. This study performed a c

Characterization of Magnetic Nanoscale Systems: From Molecules to Particles and Self-Assembled Chains

This thesis characterizes magnetic nanoscale systems with increasing size and aspect ratio using synchrotron radiation-based spectroscopy and microscopy techniques, combined with conventional magnetometry. The systems studied are molecular magnets, bimagnetic nanoparticles and self-assembled magnetic nanochains.Single-molecule magnets are compounds that exhibit magnetic bistability and hysteresis

Cellular proteo-transcriptomic changes in the immediate early-phase of lentiviral transduction

Lentivirus-based vectors derived from human immunodeficiency viruses type 1 and 2 (HIV-1 and 2) are widely used tools in research and may also be utilized in clinical settings. Like their parental virions, they are known to depend on the cellular machinery for successful gene delivery and integration. While most of the studies on cellular proteomic and transcriptomic changes have focused on the la

Ex vivo MRI atlas of the human medial temporal lobe : characterizing neurodegeneration due to tau pathology

Tau neurofibrillary tangle (NFT) pathology in the medial temporal lobe (MTL) is closely linked to neurodegeneration, and is the early pathological change associated with Alzheimer’s disease (AD). To elucidate patterns of structural change in the MTL specifically associated with tau pathology, we compared high-resolution ex vivo MRI scans of human postmortem MTL specimens with histology-based patho

The potential of degrowth and buen vivir in addressing underdevelopment and conflict in the Global South

What is the potential role of degrowth and buen vivir in addressing underdevelopment and conflict in the Global South? Underdevelopment and conflict are often portrayed as the most important challenges for countries in the Global South. Not only are they important, but they are also related; the level of development is seen to present an indication for the risk of violent conflict and civil war. P

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

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

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

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
