Feasibility and limitations of quantitative SPECT for 223Ra
The aim of this paper is to investigate the feasibility and limitations of activity-concentration estimation for 223Ra using SPECT. Phantom measurements are performed using spheres (volumes 5.5 mL to 26.4 mL, concentrations 1.6 kBq mL-1 to 4.5 kBq mL-1). Furthermore, SPECT projections are simulated using the SIMIND Monte Carlo program for two geometries, one similar to the physical phantom and the
Maxwell's demon in a double quantum dot with continuous charge detection
Converting information into work has, during the past decade, gained renewed interest as it gives insight into the relation between information theory and thermodynamics. Here, we theoretically investigate an implementation of Maxwell's demon in a double quantum dot and demonstrate how heat can be converted into work using only information. This is accomplished by continuously monitoring the charg

Vitamin D status and cardiometabolic risk markers in young Swedish children : A double-blind randomized clinical trial comparing different doses of vitamin D supplements
Background: Observational studies have linked low vitamin D status to unfavorable cardiometabolic risk markers, but double-blinded vitamin D intervention studies in children are scarce. Objectives: The aim was to evaluate the effect of different doses of a vitamin D supplement on cardiometabolic risk markers in young healthy Swedish children with fair and dark skin. Methods: Cardiometabolic risk m
Exploring differences in how males and females leverage trust and reputation in driving online purchase intentions
How customers develop purchase intentions in online shopping has been a perennial area of interest. In this research note, we ask whether males and females leverage trust in and perceive reputation of online retailers differently in reporting purchase intentions. Drawing on the broader literature on differences in males and females in online shopping behaviors, we propose that females rely on repu
From Mars to Venus: Alteration of trust and reputation in online shopping
How customers develop purchase intentions in online shopping has been an area of recent interest. In this study, we ask whether males and females leverage trust into and perceived reputation of online retailers differently in reporting purchase intentions. Drawing on the literature on differences in males and females in online shopping behaviors, we propose that females rely on reputation in devel

Det er kjent fra før at langdistansebinding av refleksive pronomen forekommeri norsk. Fenomenet har blitt kobla til logoforisitet, men det har også blitt hevdaat langdistanse binding er mulig i visse ikke-logoforiske kontekster. I denne artikkelenargumenterer jeg for at langdistansebinding i norsk alltid er logoforisk,og at det samme gjelder for mellomdistansebinding. Det er bare lokal bindingsom Det er kjent fra før at langdistansebinding av refleksive pronomen forekommer i norsk.

Performance analysis and optimization of power systems with spatially correlated noise
Based on stochastic differential equations (SDEs), we analyse the overall performance of heterogeneous power systems network, subject to spatially distributed and correlated noises with random initial conditions. We determine bounds on the H2 norm of the heterogeneous system based on a closedform of the norm of the homogeneous power system. Then, we formulate possible scenarios for performance opt
A framework for resource recovery from wastewater treatment plants in megacities of developing countries
In developing countries, there is often a lack of a comprehensive data set that supports the development of coherent policies on resource recovery from wastewater treatment. This paper aims to contribute to the elaboration of resource recovery projects by providing accurate and updated data from wastewater treatment plants such as those located in the region of the Macrometropolis of Sao Paulo. Th
Impact on Seawater Composition from Brine Disposal at EMU Desalination Plant
This study deals with the desalination plant at the Eastern Mediterranean University (Cyprus) and its environmental impact. The reverse osmosis plant produces normally 42m3/hr potable water from 120m3/hr feed. The feed concentration reaches up to 36,000ppm TDS, while an approximate amount of 73.8m3/hr is led out from a pipe of 10inches diameter with a concentration of about 56,000ppm and the perme
Estimated Future Production of Desalinated Seawater in the MENA Countries and Consequences for the Recipients
Seawater desalination constitutes an important source for water supply to the population bordering the Arabian Gulf, the Mediterranean Sea, and the Red Sea. Desalination has advantages and disadvantages which may depend on the region, location, technology, impact and amount of fresh water production. Desalination may also have other impacts. For example, chemicals added in the pre-treatment stages
Developing New Measuring Technique Controlling Desalination Brine Concentration
Desalination is an important method and cost effective for producing potable water and is a rapidly growing technology worldwide. According to the International Desalination Association, IDA data base the amount of desalinated water soon will reach the 100 MCM per day, which means double of this amount (200 MCM/day) is called brine discharge or rejected amount. In this study, we planned to follow

Wildcat bankers or political failure? : The Irish financial pantomime, 1797–1826
Using a new biography of banks, we examine the stability of Irish banking from 1797 to 1826 by constructing a failure rate series. We find that the ultimate cause of the frequent and severe banking crises was the crisis-prone structure of the banking system, which was designed to benefit the political elite. There is little evidence to suggest that wildcat banking or the failure of the Bank of Ire
Modulating Charge-Carrier Dynamics in Mn-Doped All-Inorganic Halide Perovskite Quantum Dots through the Doping-Induced Deep Trap States
Transition-metal ion doping has been demonstrated to be effective for tuning the photoluminescence properties of perovskite quantum dots (QDs). However, it would inevitably introduce defects in the lattice. As the Mn concentration increases, the Mn dopant photoluminescence quantum yield (PLQY) first increases and then decreases. Herein the influence of the dopant and the defect states on the photo
Determinants of serum concentrations of perfluoroalkyl acids (PFAAs) in school children and the contribution of low-level PFAA-contaminated drinking water
Little is known about the demographic/life-style/physiological determinants explaining the variation of serum perfluoroalkyl acid (PFAA) concentrations in children. We identified significant determinants in children and investigated the influence of low-level PFAA-contaminated drinking water (DW) (
Evolutionary roads leading to low effective spins, high black hole masses, and O1/O2 rates for LIGO/Virgo binary black holes
All ten LIGO/Virgo binary black hole (BH-BH) coalescences reported following the O1/O2 runs have near-zero effective spins. There are only three potential explanations for this. If the BH spin magnitudes are large, then: (i) either both BH spin vectors must be nearly in the orbital plane or (ii) the spin angular momenta of the BHs must be oppositely directed and similar in magnitude. Then there is
