Selective oxidation of benzyl alcohols with molecular oxygen as the oxidant using Ag-Cu catalysts supported on polyoxometalates

We report an efficient process for the oxidation of benzyl alcohols using molecular oxygen as the oxidant catalyzed by Ag-Cu catalysts supported on polyoxometalates (Ag-Cu/POM). The Ag-Cu/POM catalyst was prepared by galvanic displacement in the presence of polyvinyl pyrrolidone and polyethylene glycol. The catalysts were characterized using Fourier transform infrared spectroscopy (FTIR), ultravio

Signal quality assessment of a novel ecg electrode for motion artifact reduction

Background: The presence of noise is problematic in the analysis and interpretation of the ECG, especially in ambulatory monitoring. Restricting the analysis to high-quality signal segments only comes with the risk of excluding significant arrhythmia episodes. Therefore, the development of novel electrode technology, robust to noise, continues to be warranted. Methods: The signal quality of a nove

”Jag ser till att bli uppfattad som en vanlig DDR-medborgare”: musikforskaren Gerd Schönfelder, Kungl. Musikaliska akademien och Stasi

This article is a case study of the contacts between the music sector in Sweden and the GDR in the 1970s, 1980s and 1990s. The case is the activities of the East-German musicologist and music administrator Gerd Schönfelder (1936–2000) in Sweden at that time, and the debate that arose in the early 1990s when he was accused of having worked for the East German security service, Stasi. The purpose is

Strengthened workplace relationships facilitate recovery at work – qualitative experiences of an intervention among employees in primary health care

Background: The literature on workplace interventions focusing on recovery is scarce; hence this study intends to expand that knowledge. An intervention was run for one year, aiming at increasing the experience of recovery during the workday among primary health care employees. During the intervention, different forms of recovery activities were integrated into the daily work at six primary health

Assessment of future EV charging infrastructure scenarios for long-distance transport in Sweden

Over the last two decades, electrification has gained importance as a means to decarbonise the transport sector. As the number of Electric Vehicles (EVs) increases, it is important to consider broader system aspects as well, especially when deciding the type, coverage, size and location of the charging infrastructure required. This article proposes a new approach using agent-based simulations to a

Equilibria and Systemic Risk in Saturated Networks

We undertake a fundamental study of network equilibria modeled as solutions of fixed-point equations for monotone linear functions with saturation nonlinearities. The considered model extends one originally proposed to study systemic risk in networks of financial institutions interconnected by mutual obligations. It is one of the simplest continuous models accounting for shock propagation phenomen

Lawrence Summers Deserves a Nobel Prize for Reviving the Theory of Secular Stagnation

Lawrence Summers produced a big upset within the economics profession when he revived Alvin Hansen’s theory of secular stagnation, which had been thought of as an old-Keynesian fallacy. While some economists like Brad DeLong and Paul Krugman instantly recognized Summers’s contribution, a large share of the economics profession remained skeptical at first. Whereas most New Keynesian models allow fo

Occupational value outcomes among people with mental health issues participating in activity-based interventions–The importance of internal and external factors

Background: Perceived occupational value is an important treatment outcome but is still relatively unexplored as a phenomenon. Aim: To evaluate whether the Balancing Everyday Life (BEL) intervention for people with mental health issues was effective compared to Standard Occupational Therapy (SOT) regarding improvement on three dimensions of occupational value (concrete, socio-symbolic and self-rew

Blood-based biomarkers for Alzheimer's disease

Neurodegenerative disorders such as Alzheimer's disease (AD) represent a mounting public health challenge. As these diseases are difficult to diagnose clinically, biomarkers of underlying pathophysiology are playing an ever-increasing role in research, clinical trials, and in the clinical work-up of patients. Though cerebrospinal fluid (CSF) and positron emission tomography (PET)-based measures ar

The consequences of timing norms and term limits on local agency

Incorporating time as a unit of analysis can enrich the study of agency by showing the specific ways in which actors are temporally constrained when responding to economic disturbances. In this paper, this is done by examining how the behavior of actors is affected by timing norms such as term limits that may be associated with an actor's position, as for example, an elected mayor or university vi

Rate of MIMO Systems with CSI at Transmitter and Receiver from Pilot-Aided Estimation

We consider realistic multiple input multiple output antenna systems operating over spatially colored channels with instantaneous, albeit imperfect, channel state information at the receiver and only covariance knowledge available at the transmitter. We focus on pilot-aided channel estimation in which the receiver uses minimum mean square error channel estimation. For such a setup, our goal is the

Bioassays on ultrasonically trapped microbead clusters in microfluidic systems

The handling of biochemically functionalised beads or particles is becoming increasingly important in µTAS. Bead-based analysis of e.g. proteins can be made sensitive due to the large active surface area and flexible by chemical design of the bead surface. We have developed a microfluidic device utilising an array of integrated and individually controlled ultrasonic microtransducers for particle t

CAN AN ENERGY-COMPENSATED SOLID-STATE X-RAY DETECTOR BE USED FOR RADIATION PROTECTION APPLICATIONS AT HIGHER PHOTON ENERGIES?

The objective of this study was to investigate the characteristics of a solid-state detector commonly available at hospitals for parallel use as a real-time personal radiation monitor following radiation emergency situations. A solid-state detector probe with an inherent filtration (R100, RTI Electronics AB, Mölndal, Sweden) was chosen for evaluation. The energy dependence and the linearity in sig

Techniques of peripheral nerve repair.

Nerve injuries extend from simple nerve compression lesions to complete nerve injuries and severe lacerations of the nerve trunks. A specific problem is brachial plexus injuries where nerve roots can be ruptured, or even avulsed from the spinal cord, by traction. An early and correct diagnosis of a nerve injury is important. A thorough knowledge of the anatomy of the peripheral nerve trunk as well

Ta plats eller få plats? : Studier av marginaliserade människors förändrade vardagsliv

Syftet är att studera och analysera processer vars mål är att förändra vardagen för två marginaliserade grupper, så att de i större utsträckning blir delaktiga i samhället. De två undersökta grupperna är manliga unga narkomaner och äldre utvecklingsstörda. Avhandlingen består av tre geografiska perspektiv: 1) det tidsgeografiska synsättet, 2) känslan för platsen och 3) socialgeografiska teorier omThe aim is to study and analyse processes intended to change the daily lives of two marginalised groups and enable them to participate to a greater extent in the community. The two marginalised groups are young male drug addicts and older intellectually disabled. The thesis is permeated by three geographic perspectives: 1) the time-geographic approach, 2) sense of place and 3) social-geographic th

Does Caring for Parents Take its Toll? Gender Differences in Caregiving Intensity, Coresidence, and Psychological Well-Being Across Europe

Given population ageing and the emphasis on in-home care, more working-age adults are facing the demands of providing unpaid care to the elderly with potential implications for their own well-being. Such effects likely vary across Europe because care is differently organized with a differing emphasis on public support, dependence on family, and orientation toward gender equality. We studied the re

Tau burden is associated with cross-sectional and longitudinal neurodegeneration in the medial temporal lobe in cognitively normal individuals

Background: Neurofibrillary tangle pathology is thought to drive neurodegeneration in beta-amyloid positive (A+) cognitively normal (CN) individuals, i.e., preclinical Alzheimer’s disease (AD).However, in beta-amyloid negative (A-) CN, the contribution of tau pathology [primary age-related tauopathy (PART)] to neurodegeneration remains uncertain. We investigate the correlation between tau burden m

Alkylglucosides - physical chemical properties

The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. The two parts are linked together with a glucoside bond. In nature, the building and breakage of a glu

Cashflow Investment Relationship: Empirical Evidence of Chinese Financial Market

Purpose: In this study, we examine the data from Chinese companies to test the relationship between cash flow and investment. While a wide assortment of previous research has examined the relationship between cash flow and investment, they have largely focused on empirical analysis from an US or a Western perspective. But, to date, little attention has been paid to such relationship using empirica
