Development and Life Cycle Assessment of Polyester Binders Containing 2,5-Furandicarboxylic Acid and Their Polyurethane Coatings

This work presents a new polyester binder based on 2,5-furandicarboxylic acid (FDCA) as precursors of polyurethane (PU) coatings. The new 100% bio-based structure is composed of four different monomers such as glycerine (Gly), 1,3-propanediol (1,3-PD), 2,5-furandicarboxylic acid (FDCA) and succinic acid (SA). The corresponding PU coating was obtained by crosslinking with a conventional polyisocyan

The Church of Yimrhane Kristos : An Archaeological Investigation

The purpose of this thesis is to augment our understanding of the Church of Yimrhane Kristos, and the Lasta period in which it was built, from the study of a variety of source materials. Due to the fact that the Lasta period suffers from the absence of adequate and reliable literary sources, this study largely depends on the elements of historic buildings as the basic data source. Using archaeomet

A World of Persons

Detta är en studie i det internationella tänkandets subjekt. Människor och stater, om än ofta betraktade som varandras motsatser, delar en sak: de är det internationella tänkandets huvudsakliga subjekt. Avhandlingens argumentet är att orsaken till detta står att finna i det språk genom vilket subjektskap artikuleras, personbegreppets språk, som stipulerar vissa kriterier – i första hand rationalitThis is a study of subjecthood in international thought. Human beings and states, while often held to be opposed to one another, share this: they are international thought’s key subjects. The following chapters attempt to answer the question of why that is. The main argument advanced is that this is because of the particular language in which subjecthood is articulated, the language of personhood,

Biodiversity offsets may miss opportunities to mitigate impacts on ecosystem services

Biodiversity offsets are most commonly used to mitigate the adverse impacts of development on biodiversity, but some offsets are now also designed to support ecosystem services (ES) goals. Here, we assemble a global database of biodiversity offsets (n = 70) to show that 41% already take ES into consideration, with the objective of enhancing cultural, regulating, and provisioning services. We found

Different populations of CD11b + dendritic cells drive Th2 responses in the small intestine and colon

T-helper 2 (Th2) cell responses defend against parasites. Although dendritic cells (DCs) are vital for the induction of T-cell responses, the DC subpopulations that induce Th2 cells in the intestine are unidentified. Here we show that intestinal Th2 responses against Trichuris muris worms and Schistosoma mansoni eggs do not develop in mice with IRF-4-deficient DCs (IRF-4f/f CD11c-cre). Adoptive tr

Follow-up after curative surgery for colorectal carcinoma - Randomized comparison with no follow-up

PURPOSE: This study investigated the value of intense follow-up compared with no follow-up after curative surgery of cancer in the colon or rectum. METHODS: One hundred seven patients were randomized to no follow-up (control group; n=54) or intense follow-up (follow-up group; n=53) after surgery and early postoperative colonoscopy. Patients in the follow-up group were followed at frequent interval

Why Low Levels of Democracy Promote Corruption and High Levels Diminish It

Theory predicts democracy should reduce corruption. Yet, scholars have found that while corruption is low at high levels of democracy, it is high at modest levels, as well as low when democracy is absent. A weakness of studies that aim to explain this inverted curvilinear relationship is that they do not disaggregate the complex concepts of democracy and corruption. By contrast, this paper disaggr

A dual-action peptide-containing hydrogel targets wound infection and inflammation

There is a clinical need for improved wound treatments that prevent both infection and excessive inflammation. TCP-25, a thrombin-derived peptide, is antibacterial and scavenges pathogen-associated molecular patterns (PAMPs), such as lipopolysaccharide, thereby preventing CD14 interaction and Toll-like receptor dimerization, leading to reduced downstream immune activation. Here, we describe the de

Crop pests and predators exhibit inconsistent responses to surrounding landscape composition

The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity

Phenotypic antibody discovery and mining of complex antibody libraries

Therapeutic antibodies are the fastest growing class of drugs but suffer from a crowded target-space where many antibodies, against a few targets, are developed in parallel. The aim of this thesis is to find methods to enable discovery of novel antibody-target combinations and thereby increase the target-space. A strategy to achieve this is to use phage display antibody libraries and selection on

Statistical modeling of the atrioventricular node during atrial fibrillation : Data length and estimator performance

The atrioventricular (AV) node plays a central role during atrial fibrillation (AF). We have recently proposed a statistical AV node model defined by parameters characterizing the arrival rate of atrial impulses, the probability of an impulse choosing either one of the dual AV nodal pathways, the refractory periods of the pathways, and the prolongation of refractory periods. All model parameters a

Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers in Myocardial Infarction Patients With Renal Dysfunction

BACKGROUND: There is no consensus whether angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) should be used for secondary prevention in all or in only high-risk patients after an acute myocardial infarction (AMI).OBJECTIVES: This study sought to investigate whether ACEI/ARB treatment after AMI is associated with better outcomes across different risk profiles, inc

Focal F0 peak shape and sentence mode in Swedish

Shape characteristics of rising-falling accentual F0 peaks of Stockholm Swedish Accent I words in narrow focus are studied in a corpus of 287 read sentences. The corpus includes statements and three types of polar questions. Results reveal a clear effect of sentence mode on the shape of the accentual rises: Statements are predominantly characterized by convex rises, questions by concave rises.

A comparison of polar transmitter architectures using a GaN HEMT power amplifier

In this paper three transmitter architectures are compared, that each use the low-frequency envelope and high-frequency phase component of an RF signal. A power amplifier (PA) with Pulse Width Modulation by Variable Gate Bias (PWMVGB) is compared to an Envelope Elimination and Restoration (EER) and Envelope Tracking (ET) configuration. The test circuit is implemented using a discrete GaN HEMT powe

Arguing from Reception History for the Viability of Rational Reconstruction: A Case Study Involving The Reception of Cartesian Ethics in an Anglophone Context From 1650

I argue that Lisa Shapiro’s rational reconstruction of Descartes’s provisional moral code in terms of a broad conception of morality supplies us with an interpretative framework that make historiographical sense of the reception of Descartes’s moral philosophy in an Anglophone context on three occasions: the appeal to Descartes made by Henry More, Henry Sidgwick’s abrupt dismissal, and the ensuing

The rheumatoid finger : Treatment concepts and indications for surgery

Synovial proliferation in rheumatoid arthritis causes capsular distension, destruction of tendons and ligaments, and erosion of bone. The classic deformities in rheumatoid arthritis, like boutonnière or swan neck, are not consistent, and each patient may have his or her own pattern of deformities. The anatomic arrangement of the tendons enables motion of the proximal interphalangeal (PIP) joint is
