Analyze! : Crafting your data in qualitative research

Is there an easy way to analyze interviews, observations and documents? The answer is no. Analytical work is notoriously multilayered and there is undoubtedly more than one approach. But this book shows how it can go more smoothly. The authors maintain that all analysis involves three activities: sorting, reducing and arguing. If the researcher or student can sort and organize the material, cut ou

Regionalization and spatial analysis of precipitation of the Urmia Lake Basin, Iran

The spatial patterns of precipitation regarding physiography and atmospheric circulations in the Lake Urmia Basin have been investigated. Daily rainfall time series for the 50 most reliable precipitation stations for the period 1980-2010 were analyzed to detect the regional precipitation pattern. To identify rainfall homogeneous regions, principal component analysis was applied to the precipitatio

Long-term relationships between climate oscillation and basin-scale hydrological variability during rainy season in eastern Northeast Brazil

The high variability in the hydrological regime of the Eastern Hydrological Region (EHR) of Northeast Brazil often results in floods and droughts, leading to serious socio-economic issues. Therefore, this work aimed to investigate connections between spatiotemporal hydrological variability of the EHR and large-scale climate phenomena. Multivariate statistical techniques were applied to relate clim

Climate warming effects on hydropower demand and pricing in California

High-elevation hydropower units in California might be sensitive to climate warming since they have been designed to take advantage of snowmelt and have low built-in storage capacities. Snowmelt is expected to shift to earlier in the year and the system might not be able to store sufficient water for release in high-electricity-demanding periods. Previous studies have tried to explore the climate

Investigations on enhanced Fischer–Burmeister NCP functions : application to a rate-dependent model for ferroelectrics

This contribution deals with investigations on enhanced Fischer–Burmeister nonlinear complementarity problem (NCP) functions applied to a rate-dependent laminate-based material model for ferroelectrics. The framework is based on the modelling and parametrisation of the material’s microstructure via laminates together with the respective volume fractions. These volume fractions are treated as inter

Hereditary colorectal cancer diagnostics in southern Sweden : retrospective evaluation and future considerations with emphasis on Lynch syndrome

Overlapping phenotypes between different hereditary colorectal cancer (CRC) syndromes together with a growing demand for cancer genetic testing and improved sequencing technology call for adjusted patient selection and adapted diagnostic routines. Here we present a retrospective evaluation of family history of cancer, laboratory diagnostic procedure, and outcome for 372 patients tested for Lynch s

FGFR3 mutation increases bladder tumourigenesis by suppressing acute inflammation

Recent studies of muscle-invasive bladder cancer show that FGFR3 mutations are generally found in a luminal papillary tumour subtype that is characterised by better survival than other molecular subtypes. To better understand the role of FGFR3 in invasive bladder cancer, we examined the process of tumour development induced by the tobacco carcinogen OH-BBN in genetically engineered models that exp

Educational inequalities in fracture-related mortality using multiple cause of death data in the Skåne region, Sweden

AIM: To assess the absolute and relative educational inequalities in mortality from hip and non-hip fractures in Skåne region, Sweden.METHODS: We conducted a population-based open cohort study. People aged 30-99 years, resident in the region during 1998-2013 ( n = 999, 148) were followed until death, their 100th birthday, relocation outside Skåne, or the end of 2014. We obtained individual-level d

Factors associated with patients' willingness to consider joint surgery after completion of a digital osteoarthritis treatment program : A prospective cohort study

OBJECTIVES: To examine patient willingness and possible shift in willingness for surgery and to investigate factors associated with this shift, following participation in the digital non-surgical osteoarthritis (OA) treatment program Joint Academy.METHODS: 458 individuals (mean age 62±5.6 years, 67% women) with diagnosed hip or knee were evaluated after six weeks in Joint Academy, comprising educa

Athlete’s Heart : Diagnostic Challenges and Future Perspectives

Distinguishing between adaptive and maladaptive cardiovascular response to exercise is crucial to prevent the unnecessary termination of an athlete’s career and to minimize the risk of sudden death. This is a challenging task essentially due to the substantial phenotypic overlap between electrical and structural changes seen in the physiological athletic heart remodeling and pathological changes s

Predictors of responses to clinic-based childhood obesity care

Background/Objective: Lifestyle modification is the therapy of choice for childhood obesity, yet the response rate is variable and may be affected by genetic factors. We aimed to investigate predictors of poor response to lifestyle modification obesity treatment in children. Methods: A prospective cohort study of 434 youths (64.5% females) between 4 and 20 years of age undergoing a standard care o

Prostate cancer risk assessment in men with an initial P.S.A. below 3 ng/mL : results from the Göteborg randomized population-based prostate cancer screening trial

Abstract Objective: To evaluate the long-term outcome of men with an initial prostate-specific antigen (PSA) level below 3 ng/mL and whether the free-to-total (F/T PSA) ratio is a useful prognostic marker in this range. Materials and methods: This study is based on 5,174 men aged 50–66 years, who in 1995–1996 participated in the first round of the Göteborg randomized screening trial (initial T-PSA

Effects of free omega-3 carboxylic acids and fenofibrate on liver fat content in patients with hypertriglyceridemia and non-alcoholic fatty liver disease : A double-blind, randomized, placebo-controlled study

Background: Treatment with omega-3 fatty acids and fenofibrates reduces serum triglyceride levels, but few studies have compared the effect of these agents on liver fat. Objective: The aim of the EFFECT I trial (NCT02354976) was to determine the effects of free omega-3 carboxylic acids (OM-3CA) and fenofibrate on liver fat in overweight or obese individuals with non-alcoholic fatty liver disease a

Parental alcohol use disorder and offspring marital outcomes

Aims: We tested whether parental alcohol use disorder (AUD) predicted adult offspring's likelihood of marriage and marriage to an AUD-affected spouse; whether effects differed as a function of the sex or number of affected parents; and whether they were robust to confounders. Design: Sex-stratified Cox and logistic regression models. Setting: Sweden. Participants: A total of 1 171 070 individuals

Reaction mechanism of formate dehydrogenase studied by computational methods

Formate dehydrogenases (FDHs) are metalloenzymes that catalyse the reversible conversion of formate to carbon dioxide. Since such a process may be used to combat the greenhouse effect, FDHs have been extensively studied by experimental and theoretical methods. However, the reaction mechanism is still not clear; instead five putative mechanisms have been suggested. In this work, the reaction mechan

Characterization of habenular neurocircuitry. A potential novel target for treating depression.

In the last decade, there has been an explosion of interest within the psychiatric research community in a small diencephalic brain region called the habenula. It has been uncovered as a key regulator of monoaminergic transmission, playing a fundamental role in decision making, behavioral flexibility, inhibitory control, sleep, pain and analgesia. Perturbation of the habenular neurocircutry in ani

Atrial fibrillation frequency tracking in ambulatory ECG signals : The significance of signal quality assessment

An approach to atrial fibrillation (AF) frequency tracking in long-term ambulatory ECG recordings is presented, comprising f-wave extraction, dominant atrial frequency (DAF) tracking, and signal quality assessment. Since poor signal quality is commonly encountered in ambulatory monitoring, a recently proposed index is employed to assess f-wave signal quality in a database containing 38 patients wi

Direct role of FLT3 in regulation of early lymphoid progenitors

Given that FLT3 expression is highly restricted on lymphoid progenitors, it is possible that the established role of FLT3 in the regulation of B and T lymphopoiesis reflects its high expression and role in regulation of lymphoid-primed multipotent progenitors (LMPPs) or common lymphoid progenitors (CLPs). We generated a Flt3 conditional knock-out (Flt3fl/fl) mouse model to address the direct role
