This chapter deals with the application of adhesives in timber engineering, including wood-based products. This work is aiming to describe the general subjects in wood gluing technology, which are characteristic to wood substrates. Firstly, an overview of the basic needs and prerequisites is given, followed by a brief overview of the characteristics of the wood material. An introduction to the gen
Glued-in rods are important connecting and reinforcing elements in modern timber engineering used in new and existing timber structures. The complex stress distribution along the bondline between rod and wood depends on the type and properties of the adhesive and the type of load application. In this chapter, different models for the determination of the shear stress distribution along the bondlin
Det stora träbyggandet har varit i blickfånget sedan våra byggregler ändrades i mitten av 1990-talet. En tydlig utveckling har skett vad gäller flervåningsbyggandet i trä. Användningen av trä i infrastrukturer som broar och vindkraftverk har också ökat, även om användningen av trä i sådana bärande utomhuskonstruktioner i allmänhet är blygsam. Genom att modifiera trä på kemisk väg kan många av de s

Background and AimsP-Coumaric acid (PCA) is one the compound that has free radical scavenging effects. This study investigates the protective effect of PCA on tissue damage in DOX-induced nephrotoxicity.MethodsThirty two Wistar rats were divided into control, PCA, DOX (15 mg/kg, i.p.) and DOX plus PCA (100 mg/kg, orally) groups. DOX-induced nephrotoxicity was indicated by marked increase in blood
Acute as well as chronic pain syndromes are common after whiplash trauma and exercise therapy is proposed as one possible intervention strategy. The aim of the present systematic review was to evaluate the effect of exercise therapy in patients with Whiplash-Associated Disorders for the improvement of neck pain and neck disability, compared with other therapeutic interventions, placebo interventio
BackgroundEarly life factors influence the number of nephrons a person starts life with and a consequence of that is believed to be premature kidney ageing. Thus, we aimed to identify early life factors associated with cystatin C and creatinine-based estimated glomerular filtration (eGFR) rate equations and urine -albumin-to-creatinine ratio after a follow-up of 46–67 years.MethodsThe study includ
Svensk-kinesiska forskningssamarbeten ökar, men att förhålla sig till Kina kräver kunskap, transparens och kompass. Det skriver Tommy Shih och Sylvia Schwaag Serger vid Lunds universitet.
Performance is the yardstick by which the quality of individual and collective human effort is assessed. Everywhere, performance shapes the lives of people and organizations according to its logic and demands. The quest for performance has spread to societies worldwide; it has become of central importance for our perception of our activities and our understanding of the world. Such importance call
This article discusses how Doris Lessing’s Memoirs of a Survivor and Neil Gaiman’s Neverwhere question notions of self and identity through engagement with the fantastic urban space. Through the examination of the cityscape, maturity, and reconciliation the fantastic space is seen to have a disruptive and destabilising effect on the narrative and on the characters, which ultimately encourages a re
Industrial catalysts are often comprised of nanoparticles supported on high-surface-area oxides, in order to maximise the catalytically active surface area and thereby utilise the active material better. These nanoparticles expose steps and corners that, due to low coordination to neighboring atoms, are more reactive and, as a consequence, are often assumed to have higher catalytic activity. We ha
Background: Childhood acute lymphoblastic leukemia (ALL) is associated with cognitive impairment in adulthood. Cognitive interference processing and its correlated functional magnetic resonance imaging (fMRI) activity in the brain have not yet been studied in this patient group.Material: Twenty-six adult childhood ALL survivors (median [interquartile range {IQR}] age, 40.0 [37.0-42.3] years) were
The integrity of isolated mitochondria can be estimated functionally using enzymatic activities or the permeability of mitochondrial membranes to molecules of different sizes. Thus, the permeability of the outer membrane to the protein cytochrome c, the permeability of the inner membrane to protons, and the permeability of the inner membrane to NAD+, NADH and organic acids using soluble matrix deh
This thesis asks when and why interest groups influence political parties. I address this question in two ways: 1) by examining the organizational ties between parties and interest groups, given that party-interest group ties may constitute an important step on groups' way to influence, and 2) by more directly examining interest group influence on parties. By doing this, the thesis contributes to
Transition between stream and droplet regimes in a coflow is typically achieved by adjusting the capillary numbers (Ca) of the phases. Remarkably, we experimentally evidence a reversible transition between the two regimes by controlling exposure of the system to acoustic standing waves, with Ca fixed. By satisfying the ratio of acoustic radiation force to the interfacial tension force, , experimen
Rationale: Untreated obstructive sleep apnea (OSA) is associated with adverse outcomes in patients with coronary artery disease (CAD). Continuous positive airway pressure (CPAP) is the most common treatment, but despite interventions addressing established adherence determinants, CPAP use remains poor. Objectives: To determine whether physiological traits that cause OSA are associated with long-te
Physical activity may prevent anxiety, but the importance of exercise intensity, sex-specific mechanisms, and duration of the effects remains largely unknown. We used an observational study design to follow 395,369 individuals for up to 21 years to investigate if participation in an ultralong-distance cross-country ski race (Vasaloppet, up to 90 km) was associated with a lower risk of developing a
