Automation to benefit or ruin?The purpose of this article is to discuss and analyze how digital automation of the provision of social assistance affects the practice of social work, as part of welfare. Based on interviews with supervisors/project managers and social case workers, who work with social assistance in a strategic selection of municipalities, the opportunities and challenges that robot

Sub-trabecular strain evolution in human trabecular bone

To comprehend the most detrimental characteristics behind bone fractures, it is key to understand the material and tissue level strain limits and their relation to failure sites. The aim of this study was to investigate the three-dimensional strain distribution and its evolution during loading at the sub-trabecular level in trabecular bone tissue. Human cadaver trabecular bone samples were compres

Non-ischemic Heart Preservation via Hypothermic Cardioplegic Perfusion Induces Immunodepletion of Donor Hearts Resulting in Diminished Graft Infiltration Following Transplantation

Introduction: Many donor organs contain significant leukocyte reservoirs which upon transplantation activate recipient leukocytes to initiate acute rejection. We aimed to assess whether non-ischemic heart preservation via ex vivo perfusion promotes immunodepletion and alters the inflammatory status of the donor organ prior to transplantation. Methods: Isolated porcine hearts underwent ex vivo hypo

The head direction circuit of two insect species

Recent studies of the Central Complex in the brain of the fruit fly have identified neurons with activity that tracks the animal’s heading direction. These neurons are part of a neuronal circuit with dynamics resembling those of a ring attractor. The homologous circuit in other insects has similar topographic structure but with significant structural and connectivity differences. We model the conn

On a class of random walks in simplexes

We study the limit behaviour of a class of random walk models taking values in the standard d-dimensional simplex. From an interior point z, the process chooses one of the vertices of the simplex, with probabilities depending on z, and then the particle randomly jumps to a new location z′ on the segment connecting z to the chosen vertex. In some special cases, using properties of the Beta distribu

Kardiellt troponin – en biomarkör för hjärt–kärlsjukdom vid KOL

Chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) are frequently associated and share common risk factors, pathophysiological processes, symptoms and clinical signs. Ischemic heart disease, heart failure, pulmonary hypertension and atrial fibrillation are common comorbidities of COPD. COPD has been described as an independent risk factor for CVD. Cardiac troponin elevat

Sintering and reaction behavior in Ni-Ti powder mixtures

The present study focuses on in situ as well as ex situ studies on the sintering of pre-compacted powder mixtures of 50 at% Nickel-50 at %Titanium. In situ studies were carried out by monitoring the changes in morphology of the fracture surface of the compact continuously during heating in the hot stage of an environmental scanning electron microscope. Results on the initiation of sintering and it

Dynamic studies on the sintering of compacted metal powders using an environmental scanning electron microscope

The sintering of pre-pressed powders of iron, copper and nickel has been studied in situ using an Environmental scanning electron microscope. The small samples were slowly heated to sintering temperatures in a reducing atmosphere. Continuous monitoring of the fracture surface of the sample revealed the initial formation of inter-particle bonds at relatively low temperatures for fine particles. The

Modification of PES ultrafiltration membranes by cationic polyelectrolyte Praestol 859: Characterization, performance and application for purification of hemicellulose

Novel approach for membrane modification to improve separation performance and antifouling stability was proposed. It involves using of 0.1–0.3 wt.% aqueous solutions of Praestol 859 (cationic polyelectrolyte based on copolymer of acrylamide and 2-acryloxyethyltrimethylammonium chloride) as coagulants upon membrane preparation via non-solvent induced phase separation. It was shown that the additio

Correlation between membrane surface properties, polymer nature and fouling in skim milk ultrafiltration

The fouling of the membranes in skim milk ultrafiltration with the nominal molecular weight cut-off (MWCO) of 100 kDa fabricated from different polymers (polysulfone (PSF), polysulfonamide (PSA), aromatic polyamide (PA), polyacrylonitrile (PAN), cellulose acetate (CA) and regenerated cellulose (RC)) was studied. The membrane structure and physical-chemical properties of the selective layer were an

Preventing Parastomal Hernia After Ileal Conduit by the Use of a Prophylactic Mesh : A Randomised Study

Background: Parastomal hernia (PSH) after urinary diversion with ileal conduit is frequently a clinical problem. Objective: To investigate whether a prophylactic lightweight mesh in the sublay position can reduce the cumulative incidence of PSH after open cystectomy with ileal conduit. Design, setting, and participants: From 2012 to 2017, we randomised 242 patients 1:1 to conventional stoma constr

Linguistic : Application of LSA to predict linguistic maturity and language disorder in children

In this chapter we will describe applications of latent semantic analysis to assess semantic linguistic maturity in children and how well the method can predict whether a child has developmental language disorder (DLD), based on orally produced narratives. Assessment of narrative ability in preschool years captures important cognitive, linguistic and socio-pragmatic skills and is an important prog

SemanticExcel.com : An online software for statistical analyses of text data based on natural language processing

The overall aim of this chapter is to present a guide in how to efficiently measure and statistically analyze text and numerical data using the online software SemanticExcel.com; we will focus on the following main functions: 1. Computing semantic similarity scores between the semantic representations of two sets of texts. 2. Testing whether the semantic representations of two sets of texts statis

Integrated multimagnet systems

The design trend for the magnet system of modern synchrotron light sources is moving towards smaller magnet apertures with a reduction of magnet dimensions as a consequence. There are several reasons for this: • to increase the number of focusing cells in a given ring circumference • to increase the multipole field strengths • to reduce the total cost of the magnet and vacuum-systems This chapter

Neuronal Replacement as a Tool for Basal Ganglia Circuitry Repair : 40 Years in Perspective

The ability of new neurons to promote repair of brain circuitry depends on their capacity to re-establish afferent and efferent connections with the host. In this review article, we give an overview of past and current efforts to restore damaged connectivity in the adult mammalian brain using implants of fetal neuroblasts or stem cell-derived neuronal precursors, with a focus on strategies aimed t

Neuroscience : Mapping the semantic representation of the brain

Introducing the concept of semantic representation in the brain as well as highlighting their relevance for day-to-day human functioning. Presenting a brief overview of different theoretical viewpoints on semantic representation in the brain along with empirical evidence implicating brain areas designated for semantic processing. Illustrating how statistical semantics and semantic spaces have been

Activity in grafted human iPS cell-derived cortical neurons integrated in stroke-injured rat brain regulates motor behavior

Stem cell transplantation can improve behavioral recovery after stroke in animal models but whether stem cell-derived neurons become functionally integrated into stroke-injured brain circuitry is poorly understood. Here we show that intracortically grafted human induced pluripotent stem (iPS) cell-derived cortical neurons send widespread axonal projections to both hemispheres of rats with ischemic

Social psychology : Evaluations of social groups with statistical semantics

Semantic analyses are potentially important, but underutilized, tools to study social psychology. This chapter focuses on how semantic analysis, using personal pronouns, can be used to study important phenomena in social psychology. Personal pronouns can be used as proxies for social categories, and the semantic contexts associated to these pronouns can be used to study stereotypes and how groups
