Microfluidic Hydrodynamic of Gas-Liquid flow in Single Microchannel and Porous Media with Microchannel Network

In this thesis, a microfluidics platform with high-speed imaging system was built to investigate gas-liquid flow in single microchannel and interfacial instability in porous media with microchannel network:The mass transfer of slug flow in the rectangular and square microchannels was experimentally studied by using water as liquid phase and CO2 as gas phase. Depending on flow rates, flow patterns

Experimental study of gas-Liquid Mass transfer in a rectangular microchannel by digital image analysis method

Study of mass transfer in microchannels is indispensable for the design of microreactors. Gas-phase volume monitoring method has been widely used to study the mass transfer process.When using this method, bubble length was measured in most studies to calculate the bubble volume by assuming a symmetrical bubble shape. Therefore, this method is not suitable for asymmetric bubbles. The present study

Hydrodynamics of gas-liquid displacement in porous media: fingering pattern evolution at the breakthrough moment and the steady state

Gas-liquid displacement in porous media widely exists in many terrestrial/extraterrestrial subsurface resource extraction and utilization applications. The typical fingering displacement during gas invading has been well identified through extensive research efforts. Yet, the evolution of fingering structures after invading breakthrough is rarely reported. Herein, through a joint approach of exper

Back-to-back azimuthal correlations in Z + jet events at high transverse momentum in the TMD parton branching method at next-to-leading order

Azimuthal correlations in Z + jet production at large transverse momenta are computed by matching Parton-Branching (PB) TMD parton distributions and showers with NLO calculations via MCatNLO. The predictions are compared with those for dijet production in the same kinematic range. The azimuthal correlations Δ ϕ between the Z boson and the leading jet are steeper compared to those in dijet producti

When energy justice is contested: A systematic review of a decade of research on Sweden's conflicted energy landscape

The way in which we produce and consume energy has profound implications for our societies. How we configure our energy systems determines not only our chances of successfully dealing with climate change but also, how benefits and burdens of these systems are distributed. In this paper, we set out to map the literature on conflicts related to the energy system in Sweden using a framework of energy

Reduction of early surgical site and other care related infections in 3553 hip fracture patients : lessons learned from the 5-year Safe Hands project

Background: Surgical site infection (SSI) after acute hip fracture surgery is a devastating complication associated with increased suffering and mortality. The aim of the study was to investigate early SSI, sepsis, pneumonia and urinary tract infections over five years, before and after the implementation of the Safe Hands project. Methods: This was a single-centre observational study with a 5-yea

Movers and Stayers : A Study of Emigration from Sweden 1993–2014

A standard proposition in the migration literature is that emigrants are not drawn randomly from their source population, but rather compose a self-selected group in terms of labour market characteristics. Such self-selection refers to observed characteristics, such as education, or occupation, as well as unobserved characteristics such as cognitive abilities. However, due to data limitations, mos

Cell-Free Hemoglobin Concentration in Blood Prime Solution Is a Major Determinant of Cell-Free Hemoglobin Exposure during Cardiopulmonary Bypass Circulation in the Newborn

Exposure to circulating cell-free hemoglobin is a ubiquitous feature of open-heart surgery on cardiopulmonary bypass circulation. This study aims to determine the origins and dynamics of circulating cell-free hemoglobin and its major scavenger proteins haptoglobin and hemopexin during neonatal cardiopulmonary bypass. Forty neonates with an isolated critical congenital heart defect were included in

Polygenic scores for low lung function and the future risk of adverse health outcomes

AIMS: Reduced lung function and adverse health outcomes are often observed. This study characterizes genetic susceptibility for reduced lung function and risk of developing a range of adverse health outcomes.METHODS: We studied 27,438 middle-aged adults from the Malmö Diet and Cancer study (MDCS), followed up to 28.8 years. Trait-specific Polygenic scores (PGS) for forced expiratory volume in 1 s

Objekt i svenskans historia. : En studie av varierande objektsplacering i fornsvenska

I min avhandling undersöker jag varierande placering av objekt till verb i svenskans historia. Primärt undersöks placering av nominala objekt visavi negerande adverbial, och sekundärt undersöks placering av nominala objekt visavi andra argument (subjekt och objekt) i huvudsatser. Materialet som ligger till grund för avhandlingen är texter från äldre och yngre fornsvenska (1225-1526), och huvudsaklThis thesis focuses on the distribution of objects in the history of Swedish. The primary focus of the thesis is the distribution of objects relative to negation, and the secondary focus is varying order of nominal arguments in Old Swedish (1225–1526).In Modern Swedish, objects may precede the negation, often referred to as Object Shift, OS, or precede a subject, often referred to as Long Object S

Sexual Violence in Criminal Law : Presumptions, Principles and Premises in Relation to the Crime of Negligent Rape

In this chapter I analyse the recent criminalization of negligent rape in Sweden, introduced in 2018. My aim is to contribute to the discussion of criminalization as it relates to violence against women, while taking a broad view of criminalization that includes not only criminalization per se but also the application of law. My analysis of the application of the crime of negligent rape, from the

Discipline or punishment? : Sexual violence and harassment in administrative procedures at Lund University

A recent study from Lund University shows that more than 25 % of the female students have experienced sexual harassment or violence during their studies. Most of them stated they didn’t tell anyone about this, least of all anyone at university.. At the same time there seems to be a growing demand from students that university responds and takes action against sexual violence on campus. This could

Clinical frailty scale – skörhet är ett sätt att skatta biologisk ålder

The term frailty denotes a multi-dimensional syndrome characterised by reduced physiological reserves and increased vulnerability. Frailty may be used as a marker of biological age, distinct from chronological age. There are several instruments for frailty assessment. The Clinical Frailty Scale (CFS) is probably the most commonly used in the acute care context. It is a 9-level scale, derived from

Successful gene therapy of Diamond-Blackfan anemia in a mouse model and human CD34+ cord blood hematopoietic stem cells using a clinically applicable lentiviral vector

Diamond-Blackfan anemia (DBA) is an inherited bone marrow failure disorder in which pure red blood cell aplasia is associated with physical malformations and a predisposition to cancer. Twentyfive percent of patients with DBA have mutations in a gene encoding ribosomal protein S19 (RPS19). Our previous proof-of-concept studies demonstrated that DBA phenotype could be successfully treated using len

Syncope in hypertrophic cardiomyopathy (part II) : An expert consensus statement on the diagnosis and management

Syncopal events in patients with hypertrophic cardiomyopathy (HCM) are of concern as they are a vital consideration in algorithms for risk stratification for sudden cardiac death (SCD) and ICD implantation. However, the cause of syncope is often under-investigated and/or unexplained. Current syncope guidelines do not provide a detailed definition of unexplained syncope. To address this important g

From nazi concentration camp to detention in Sweden 1945 : Female survivors, sexuality, and respectability

Gunnarpshemmet was a closed detention camp for female refugees. Fifty-seven women were forcibly detained here be-tween 1945 and 1946. This article examine the camp, focusing on the internment of former concentration camp prisoners who had been transferred to Sweden with the “white buses” Red Cross rescue operation, undertaken in the spring of 1945. Gunnarpshemmet serves as a case study to shed lig
