Over the past few decades, lean management philosophies have penetrated various sectors of industry. At same time, dynamic environmental, or green, management is needed to succeed in the current green conscious market. Some research has already been conducted on the potential synergy gains of the two management philosophies, since both are known to strive towards efficient use of resources, elimin
Overt autoantibodies to the smaller isoform of glutamate decarboxylase (GAD65Ab) are a characteristic in patients with Type 1 diabetes (T1D). Anti-idiotypic antibodies (anti-Id) directed to GAD65Ab effectively prevent the binding of GAD65 to GAD65Ab in healthy individuals. Levels of GAD65Ab-specific anti-Id are significantly lower in patients with T1D, leading to overt GAD65Ab in these patients. T
Bakgrund Med en snabbt växande äldre populationsgrupp kommer även andelen med kognitiva störningar, som demens, att växa. Det är således nödvändigt med forskning på kognition och åldrande. Denna avhandling, genom fyra delarbeten, redogör för testledareffekter vid kognitionsmätningar och hur yngre födelsekohorter (generationer) presterar bättre än äldre på kognitionstester. Den kommer även förklaraGiven a growing population of older adults and the common occurrence of natural as well as pathological cognitive decline, i.e. dementia, there is a need to better understand how to accurately measure and classify level of cognitive functioning. Both using multiple test administrators to collect cognitive data and what year the participant is born (birth cohort effects) can influence participants’
Plasma accelerators present one of the most suitable candidates for the development of more compact particle acceleration technologies, yet they still lag behind radiofrequency (RF)-based devices when it comes to beam quality, control, stability and power efficiency. The Horizon 2020-funded project EuPRAXIA ("European Plasma Research Accelerator with eXcellence In Applications") aims to overcome t
Post-traumatic stress disorder (PTSD) impacts many veterans and active duty soldiers, but diagnosis can be problematic due to biases in self-disclosure of symptoms, stigma within military populations, and limitations identifying those at risk. Prior studies suggest that PTSD may be a systemic illness, affecting not just the brain, but the entire body. Therefore, disease signals likely span multipl
Electronic transport through a single-level quantum dot coupled to two ferromagnetic leads is studied in the sequential tunneling regime. Transport characteristics are calculated for arbitrary angle between magnetic moments of the electrodes. It is found that the diode feature in the transport characteristics is significantly suppressed for canted magnetic configurations. It is also shown that a s
BACKGROUND: Patients with new-onset atrial fibrillation in relation to infection are frequent in emergency departments (ED) and may require antithrombotic therapy due to increased risk of stroke. Our objective was to describe the one-year risk of stroke in ED patients with infection, new-onset atrial fibrillation and no antithrombotic therapy.METHODS: Population-based cohort study at four EDs in D
A 2H n.m.r. relaxation study of sodium dodecyl sulphate (SDS) in the micellar phase is presented. The surfactant is specifically deuterated in the α-, γ- and ω-positions. Relaxation data are obtained at two temperatures and at three field strengths, and show a dependence on the field strength. The data are analysed with the 'two-step' model of relaxation, and the fast correlation times as well as
The glutamate transporter 1 (GLT1) is upregulated during astrocyte development and maturation in vivo and is vital for astrocyte function. Yet it is expressed at low levels by most cultured astrocytes. We previously showed that maturation of human and mouse stem cell-derived astrocytes - including functional glutamate uptake - could be enhanced by fibroblast growth factor (FGF)1 or FGF2. Here, we
[Context and motivation] Quality requirements (QRs) are inherently difficult to manage as they are often subjective, context-dependent and hard to fully grasp by various stakeholders. Furthermore, there are many sources that can provide input on important QRs and suitable levels. Responding timely to customer needs and realizing them in product portfolio and product scope decisions remain the main
Background: Bisphosphonates have previously been shown to increase the density of impacted graft bone. In the present study we hypothesise that bisphosphonates also reduce early stem subsidence. We examined the effect of locally applied bisphosphonate to allografts on prosthetic micromotion and bone density in femoral stem revision with impaction grafting. Methods: 37 patients were randomised to e
Within the hematopoietic system, the Notch pathway is critical for promoting thymic T cell development and suppressing the B and myeloid lineage fates; however, its impact on NK lymphopoiesis is less understood. To study the role of Notch during NK cell development in vivo, we investigated different NK cell compartments and function in Rbp-Jkfl/flVav-Cretg/+ mice, in which Rbp-Jk, the major transc
A fundamental difference between ordinary and leisure time is for many the ability to indulge in extra-ordinary activities of both body and mind. Rooted in antiquity, the renaissance villas were often used as spaces for indulgence of artistic endeavors, be it philosophical discussions, poetry-writing or lavish parties. Of indulgence, Aristoteles wrote: ‘The self-indulgent man craves for all pleasa
The complement system resembles a double-edged sword since its activation can either benefit or harm the host. Thus, regulation of this system is of utmost importance and performed by several circulating and membrane-bound complement inhibitors. The pool of well-established regulators has recently been enriched with proteins that either share structural homology to known complement inhibitors such
