This contribution presents a modeling and optimization method for multi-column counter-current purification (MCSGP) processes. The model is based on conventional column models and by using the symmetric and cyclic steady state characteristics of the process a single column analog model was developed. The model have been used for dynamic optimization of the MCSGP process. The optimization was based

Material resources exploitation and the pressure on natural ecosystems have raised concerns over potential future resource risks and supply failures worldwide. Interest in the concept of Circular Economy has surged in recent years among policy makers and business actors. An increasing amount of literature touches upon the conceptualisation of Circular Economy, the development of ‘circular solution

Background: Recent studies have shown that quantification of myocardial perfusion (MP) at stress and myocardial perfusion reserve (MPR) offer additional diagnostic and prognostic information compared to qualitative and semi-quantitative assessment of myocardial perfusion distribution in patients with coronary artery disease (CAD). Technical advancements have enabled fully automatic quantification

The most fundamental clinical monitoring tool in traumatic brain injury (TBI) patients is the repeated clinical examination. In the severe TBI patient treated by continuous sedation in a neurocritical care (NCC) unit, sedation interruption is required to enable a clinical evaluation (named the neurological wake-up test; NWT) assessing the level of consciousness, pupillary diameter and reactivity t

The formation of neutrophil extracellular traps (NETs) is a host defence mechanism, known to facilitate the entrapment and growth inhibition of many bacterial pathogens. It has been implicated that the translocation of myeloperoxidase (MPO) from neutrophilic granules to the nucleus is crucial to this process. Under disease conditions, however, excessive NET formation can trigger self-destructive c

Tom Tyler’s theory of procedural justice argues that police may foster legitimacy by acting “procedurally just”. This can be done by granting citizens opportunities to partake in decision-making, by making decisions impartial and unbiased, and by showing dignity, respect and honesty in public interactions. Legitimacy depends on people’s assessments of fairness, Tyler argues. His psychological theo

Summary: Kidney function decreases with age; however, the long-term influence on bone density (BMD) in older women already at risk of osteoporosis is unknown. We followed kidney function and bone loss for 10 years. Declining kidney function was adversely associated with bone loss and mineral homeostasis in old women, though it attenuated with advanced aging. Introduction: Existing studies do not f

Objective: Meal ingestion is followed by a redistribution of blood flow (BF) within the splanchnic region contributing to nutrient absorption, insulin secretion and glucose disposal, but factors regulating this phenomenon in humans are poorly known. The aim of the present study was to evaluate the organ-specific changes in BF during a mixed-meal and incretin infusions. Design: A non-randomized int

Background--Family history of coronary heart disease (CHD) as well as genetic predisposition to CHD assessed by a genetic risk score (GRS) are predictors of CHD risk. It is, however, uncertain to what extent these risk predictors are mediated by major metabolic pathways. Methods and Results--Total effects of self-reported family history and a 50-variant GRS (GRS50), as well as effects mediated by

Background-Treatment with renin-angiotensin system (RAS) inhibitors might restrain the structural/electrical remodeling associated with atrial fibrillation (AF). Limited evidence exists regarding the potential benefits of RAS inhibition post-acute myocardial infarction (AMI) in patients with AF. This study sought to assess the association between RAS inhibition and all-cause mortality and new-onse

This article presents a search for flavour-changing neutral currents in the decay of a top quark into an up-type (q = c, u) quark and a Higgs boson, where the Higgs boson decays into two photons. The proton-proton collision data set analysed amounts to 36.1 fb−1 at s=13 TeV collected by the ATLAS experiment at the LHC. Top quark pair events are searched for, where one top quark decays into qH and

Prostate cancer units - hubs in the future care of men with prostate cancer Prostate cancer is the most common form of cancer in Sweden. The past decade has seen a tremendous development of new methods for diagnosing, staging, treating and rehabilitating men with suspicious or confirmed prostate cancer. This development necessitates a multidisciplinary and multiprofessional approach to the managem

Treating Life-Threatening Bleedings: Development of Recombinant Coagulation Factor VIIa provides a comprehensive understanding of the first new drug within the area of hemostasis, describing a new mechanism of action that has resulted in a modified concept of the whole hemostasis mechanism. As the treatment of life-threatening bleedings is a serious challenge for clinicians, this powerful and hist

The Crafoord Prize in Polyarthritis ranks as one of the most prestigious prizes and can be awarded only if the Royal Swedish Academy of Sciences decides the likelihood of prize worthy progress in the field, and at most every 4th year. This has happened only four times since 1982. This year the 5th Laureates were Shimon Sakaguchi, Fred Ramsdell, and Alexander Rudensky with the motivation "for their

A search is presented for the pair production of heavy vector-like T quarks, primarily targeting the T quark decays to a W boson and a b-quark. The search is based on 36.1 fb−1 of pp collisions at s=13 TeV recorded in 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Data are analysed in the lepton-plus-jets final state, including at least one b-tagged jet and a large-radius

Endoscopy is not a modern invention but the history of endoscopy goes back to ancient times in Egypt and Greece when speculums were used to inspect the nose cavity, vagina and anorectum. The modern era of endoscopy started in the 19th century with the development of straight metallic tubes with primitive light sources, such as Bozzini´s »lichtleiter« and Desormeaux´s »endoscope«. The first gastros

Loss and Damage (L&D) has been the subject of contentious debate in international climate policy for several decades. Recently, formal mechanisms on L&D have been established, but arguably through unclear language. This ambiguity is politically important, but researchers and practitioners require clearer understandings of L&D. Here we report on the first in-depth empirical study of act
