Purpose – This paper aims to develop a novel micro-ablation system to realise micrometric and well-defined hydrogel structures. To engineer a tissue it is necessary to evaluate several aspects, such as cell-cell and cell-substrate interactions, its micro-architecture and mechanical stimuli that act on it. For this reason, it is important to fabricate a substrate which presents a microtopology simi

Measurements of the adiabatic laminar burning velocities of n-heptane, iso-octane, ethanol and their binary and tertiary mixtures are reported. Non-stretched flames were stabilized on a perforated plate burner at 1 atm. The Heat Flux method was used to determine burning velocities under conditions when the net heat loss from the flame to the burner is zero. Initial temperatures of the gas mixtures

The assessment of flood vulnerability is a complex task that involves numerous uncertainties. Within this context, sensitivity analyses are crucial to better understand the variability of vulnerability index outcomes according to different input parameters. The present study sheds light on the importance of assessing the sensitivity of different criteria weights to construct flood vulnerability in

Background: Prolactin receptor (PRLR) signaling affects breastfeeding and potentially breast cancer treatment response. Methods: The prognostic impact of 20 PRLR single nucleotide polymorphisms (SNPs) in relation to adjuvant treatment groups in patients with primary breast cancer (n = 1701, 2002–2016, Sweden) was evaluated. Genomic DNA was genotyped on Illumina OncoArray, and survival analyses wit

Problem: Det finns flera teorier kring olika utdelningsstrategier. Vad forskare inte är eniga om är huruvida företagsledningar använder utdelningsförändringar för att minska informationsasymmetrin mellan ledningen och ägarna genom att informera något om företagets framtida vinst, och i så fall vad dessa signaler säger. Syfte: Studiens syfte är att undersöka huruvida det finns något samband mellan

The aim of this paper is to chart the relevant studies and research questions concerning the relationship between ICTs and Mobility in Everyday Life – a concept defined and delineated in a previous paper An Agenda for ‘Mobility in Everyday Life’ for ICT Researchers (Haddon, 2000a).

High resolution real time heat release analysis will become increasingly important in the future development of engine control systems. The increased demands on efficiency and emissions will put high demands on future engine control. Future engine concepts, for example the HCCI engine concept might crave cylinder pressure based Closed-Loop Combustion Control (CLCC). The analysis of cylinder pressu

Neisseria meningitidis is a normal commensal of human mucous membranes that is no longer considered to be restricted to the nasopharynx. Due to the practice of oral sex, the mucous membranes of the cervix, urethra or anus have become a potential infection site for this bacterium. Inserting an intrauterine device (IUD), can alter the protective barrier of the endocervical mucosa, allowing for bacte

OBJECTIVE: There is great need of biomarkers for research and clinical purposes in COPD. This study explored the relationships between ten putative plasma biomarkers of COPD and physiological measures of reduced lung function. METHODS: FEV(1), FVC, residual volume/total lung capacity (RV/TLC) and CO diffusion capacity (D(L)CO) were assessed in 357 subjects from the Swedish Twin Registry. The l

This article extends the common correlated effects pooled (CCEP) estimator to homogenous dynamic panels. In this setting, CCEP suffers from a large bias when the time span (T) of the dataset is fixed. We develop a bias-corrected CCEP estimator that is consistent as the number of cross-sectional units (N) tends to infinity, for T fixed or growing large, provided that the specification is augmented

Observational learning has shown to be a successful intervention for writing. Up until now, however, studies have only been performed with normal-hearing participants, usually highschool or university students. Additionally, there have been conflicting results in whether subjective text quality correlates with one or more objectively measured text characteristics. In this study, we measured the ef

There is an increasing interest in open source, which also goes for enterprise resource planning (ERPs) systems, especially when it comes for small and medium sized enterprises (SMEs). In this article, the focus is on the combination of open source and ERPs, and specifically on what role development of open source ERPs plays in diffusion of ERPs among SMEs. In an effort to be able to explain the i

Leishmaniasis is one of the most important neglected tropical diseases, with a broad spectrum of clinical manifestations. Among the clinical manifestations of the disease, cutaneous leishmaniasis, caused by species of Leishmania braziliensis, presents wide distribution in Brazil. In this work, we performed the cloning, expression, and purification of the enzyme superoxide dismutase of Leishmania b

PURPOSE: There is a dearth of research on coping strategies of patients with malignant lymphoma. The aim of this article is to explore how these patients cope with cancer in everyday life.METHOD: Semi-structured interviews were conducted with nine patients in Sweden. A thematic analysis was made, inspired by Antonovsky’s theory of sense of coherence. The SRQR checklist was used.

Aim: The relationship between support at home and rehospitalization has not been extensively studied until now. In particular, little is known about the impact of being assisted by migrant care workers (MCW) and rehospitalization. We aimed at investigating such a relationship in a population of older patients discharged from hospitals. Methods: Our series consisted of 506 patients aged 65 years or

Chronic low-grade inflammation, particularly in adipose tissue, is an important modulator of obesity-induced insulin resistance. The Toll-like receptor 4 (Tlr4) is a key initiator of inflammatory responses in macrophages. We performed bone marrow transplantation (BMT) of Tlr4lps-del or control C57Bl/10J donor cells into irradiated wild-type C57Bl6 recipient mice to generate hematopoietic cell-spec
