Surface irrigation performance of date palms under water scarcity in arid irrigated lands

In this paper, a study on the performance of surface irrigation of date palms in a Tunisian arid area (Douz oasis) is presented. The study is conducted in 16 plots with various sizes and soil textures over a 4-year period (2012–2015). In the first step, an assessment of total water requirements of the date palms is carried out. Then, the surface irrigation performance is analyzed using three indic

Cerebrovascular and amyloid pathology in predementia stages : The relationship with neurodegeneration and cognitive decline

Background: Cerebrovascular disease (CVD) and amyloid-β (Aβ) often coexist, but their influence on neurodegeneration and cognition in predementia stages remains unclear. We investigated the association between CVD and Aβ on neurodegenerative markers and cognition in patients without dementia. Methods: We included 271 memory clinic patients with subjective or objective cognitive deficits but withou

Nitrated nucleosome levels and neuropsychiatric events in systemic lupus erythematosus; a multi-center retrospective case-control study

Background: In patients with systemic lupus erythematosus (SLE) there is no serological test that will reliably distinguish neuropsychiatric (NP) events due to active SLE from those due to other causes. Previously we showed that serum levels of nitrated nucleosomes (NN) were elevated in a small number of patients with NPSLE. Here we measured serum NN in samples from a larger population of patients

Planar screening by charge polydisperse counterions

We study how a neutralising cloud of counterions screens the electric field of a uniformly charged planar membrane (plate), when the counterions are characterised by a distribution of charges (or valence), n(q). We work out analytically the one-plate and two-plate cases, at the level of non-linear PoissonBoltzmann theory. The (essentially asymptotic) predictions are successfully compared to numeri

Costs of Care of Agitation Associated With Dementia in 8 European Countries : Results From the RightTimePlaceCare Study

Objective To estimate the additional societal costs for people living with dementia (PwD) with agitation in home care (HC) and institutional long-term care (ILTC) settings in 8 European countries. Design Cross-sectional data from the RightTimePlaceCare cohort. Setting HC and ILTC settings from 8 European countries (Estonia, Finland, France, Germany, Netherlands, Spain, Sweden, and England). Partic

A comparison of two emergency medical dispatch protocols with respect to accuracy

Background: Emergency medical dispatching should be as accurate as possible in order to ensure patient safety and optimize the use of ambulance resources. This study aimed to compare the accuracy, measured as priority level, between two Swedish dispatch protocols - the three-graded priority protocol Medical Index and a newly developed prototype, the four-graded priority protocol, RETTS-A. Methods:

A theory of openness for software engineering tools in software organizations

Context: The increased use of Open Source Software (OSS) affects how software-intensive product development organizations (SIPDO) innovate and compete, moving them towards Open Innovation (OI). Specifically, software engineering tools have the potential for OI, but require better understanding regarding what to develop internally and what to acquire from outside the organization, and how to cooper

Within-day energy deficiency and reproductive function in female endurance athletes

We aimed to estimate and compare within-day energy balance (WDEB) in athletes with eumenorrhea and menstrual dysfunction (MD) with similar 24-hour energy availability/energy balance (EA/EB). Furthermore, to investigate whether within-day energy deficiency is associated with resting metabolic rate (RMR), body-composition, S-cortisol, estradiol, T3 , and fasting blood glucose. We reanalyzed 7-day di

Deficiency in plasmacytoid dendritic cells and type I interferon signalling prevents diet-induced obesity and insulin resistance in mice

Aims/hypothesis: Obesity is associated with glucose intolerance and insulin resistance and is closely linked to the increasing prevalence of type 2 diabetes. In mouse models of diet-induced obesity (DIO) and type 2 diabetes, an increased fat intake results in adipose tissue expansion and the secretion of proinflammatory cytokines. The innate immune system not only plays a crucial role in obesity-a

Invandring och företagande : Kunskapsöversikt

Entreprenörskap och egenföretagande framställs idag som betydelsefulla faktorer avseende både tillväxt, sysselsättnings- och integrationsproblem. I en ny kunskapsöversikt presenteras och diskuteras kunskap om invandring och företagande ur ett internationellt och svenskt perspektiv. Översikten redogör för om det finns något särskilt som karaktäriserar utlandsföddas företagande exempelvis vad gäller

Complex-coefficient systems in control

Complex-valued dynamics can be used for modeling rotationally invariant two-input two-output systems and bandpass systems when they are considered in the baseband. In a few instances, control design has been done in the complex domain, which facilitated analysis and synthesis. While previous work has been application specific, we will discuss more generally how complex valued dynamics arise, basic

Coupling and braiding Majorana bound states in networks defined in proximate two-dimensional electron gases

Two-dimensional electron gases with strong spin-orbit coupling covered by a superconducting layer offer a flexible and potentially scalable platform for Majorana networks. We predict Majorana bound states (MBSs) to appear for experimentally achievable parameters and realistic gate potentials in two designs: either underneath a narrow stripe of a superconducting layer (S stripes) or where a narrow
