Feasibility of 177Lu activity quantification using a small portable CZT-based gamma-camera

Background: In image processing for activity quantification, the end goal is to produce a metric that is independent of the measurement geometry. Photon attenuation needs to be accounted for and can be accomplished utilizing spectral information, avoiding the need of additional image acquisitions. The aim of this work is to investigate the feasibility of 177Lu activity quantification with a small

Probabilistic Modelling of EV Charging Impact on the Sub-transmission Grid

Transport electrification in Sweden is moving at a fast pace. Grid impact studies from EVs predominantly consider low-voltage grids. However, as the share of electric cars is rapidly increasing, potential grid impact at higher voltage levels needs to be considered. This paper presents a probabilistic approach to generate aggregated charging profiles for home charging at a sub-transmission grid lev

Performance evaluation of a high speed segmented rotor axial flux switched reluctance traction motor

This paper deals with the performance evaluation of a high speed axial flux switched reluctance motor for automotive traction applications. The motor makes use of a novel axial flux segmented rotor topology. The main aim of the design is to push the continuous power density as high as possible. The high speed nature of the design and the resulting high electrical frequency, as well as the machine

Measurements of the Electric Properties of the Current Collector in a Conductive Electric Road

Conductive electric road systems are charging in-frastructures that allow electric vehicles to charge while driving. Similar to that of trolleybuses, trams and metro trains conductive electric roads use a physical sliding contact to facilitate the energy transfer between vehicle and road supply. However, as conductive electric roads introduce a new application for the sliding contact, knowledge is

A cosmopolitan invader – Choreutis sexfasciella (Lepidoptera, Choreutidae) – in Cyprus : first record, molecular characterization, and a reared parasitoid

The Banyan Leaf Skeletonizer moth, Choreutis sexfasciella (Sauber, 1902) (Lepidoptera: Choreutidae), is reported from Cyprus for the first time from Ficus microcarpa L.fil. and F. benjamina L. trees in urban areas of Larnaca, Limassol, and Paphos. C. sexfasciella was originally described from the Philippines and has rapidly extended its range in the last five years into several Mediterranean count

Shrinking and financial development in Kenya and Tanzania, 1960-2020

The failure of many countries in the Global South to catch up economically to the advanced economies of the Global North has long been a topic of interest to economic historians and development economists. Traditionally, researchers focused their attention on the question of growth –how can a country achieve growth to catch up? In recent years, however, a new research programme has begun to shift

A dynamic bounding volume hierarchy for generalized collision detection

In this paper, we propose a new dynamic and efficient bounding volume hierarchy for breakable objects undergoing structured and/or unstructured motion. Our object-space method is based on different ways to incrementally update the hierarchy during simulation by exploiting temporal coherence and lazy evaluation techniques. This leads to significant advantages in terms of execution speed. Furthermor

Deactivating effects of lead on the selective catalytic reduction of nitric oxide with ammonia over a V2O5/WO3/TiO2 catalyst for waste incineration applications

Lead is one of the poisonous elements for de-NOx catalysts especially in the case of municipal waste incineration plants. Samples of a commercial selective catalytic reduction catalyst were impregnated with different amounts of Pb(NO3)(2), and their catalytic activities were studied. The XPS and SEM analysis showed higher lead concentration on the outer surface of the monolith than on the inside o

The influence of calcium and magnesium in drinking water and diet on cardiovascular risk factors in individuals living in hard and soft water areas with differences in cardiovascular mortality

Background: The role of water hardness as a risk factor for cardiovascular disease has been widely investigated and evaluated as regards regional differences in cardiovascular disease. This study was performed to evaluate the relation between calcium and magnesium in drinking water and diet and risk factors for cardiovascular disease in individuals living in hard and soft water areas with consider

Correlation potentials for a multiconfigurational-based density functional theory with exact exchange

A density functional theory based on a complete active space self consistent field (CASSCF) reference function with exact exchange is discussed. It is first shown that such a theory may be formulated with a correlation potential dependent on the density function and on the active space used. Auxiliary functions, such as the on-top two-particle density, are used to define uniquely the potential for

Impaired postural control in patients with cervico-brachial pain

Dizziness and subjective balance disturbances are common complaints in cervical pain syndromes. We assessed balance function with posturography using vibration-induced and galvanically-induced body sway in consecutive patients (n = 116) with cervico-brachial pain syndrome of more than 3 months' duration. A total of 83% of the patients showed signs of cervical root compression on MRT scans. The inc

Search for supersymmetric particles in light gravitino scenarios and sleptons NLSP

A search for sleptons, neutralinos, charginos, sgoldstinos and heavy stable charged sleptons in the context of scenarios where the lightest supersymmetric particle is the gravitino, is presented. Data collected during 2000 with the DELPHI detector at centre-of-mass energies from 204 to 208 GeV were analysed and combined with all the data collected from 1995 to 1999 at lower energies. No evidence f

Estimation of fungal growth rates in soil using C-14-acetate incorporation into ergosterol

A technique to estimate fungal growth rates in field samples was tested in soil. The technique is based on the addition of C-14-acetate to a soil slurry and the subsequent uptake and incorporation of the labelled acetate into the fungus specific substance ergosterol by the fungi. The addition of fungal inhibitors decreased acetate incorporation rates, while bacterial inhibitors did not. Fungus-fre

Soft tissue reactions around percutaneous implants: a clinical study of soft tissue conditions around skin-penetrating titanium implants for bone-anchored hearing aids

Some patients with hearing impairment cannot use conventional hearing aids. One solution for these patients is the use of bone conduction hearing aids; however, this kind of equipment is associated with several problems related to the necessity for a good contact between the transducer and the temporal bone. Direct bone contact would be an ideal solution provided that safe and reaction-free skin p

The Geneva-Copenhagen survey of the Solar neighbourhood. Ages, metallicities, and kinematic properties of ∼14 000 F and G dwarfs

We present and discuss new determinations of metallicity, rotation, age,kinematics, and Galactic orbits for a complete, magnitude-limited, andkinematically unbiased sample of 16 682 nearby F and G dwarf stars. Our∼63 000 new, accurate radial-velocity observations for nearly 13 500stars allow identification of most of the binary stars in the sampleand, together with published uvbyβ photometry, Hipp

Objective: To study reproduction in a representative group of anorexia nervosa (AN) cases. Method: Fifty-one adolescent-onset AN cases (48 women; three men), originally recruited after community screening, and 51 matched comparison cases (COMP) were interviewed 18 years after AN onset at a mean age of 32 years, regarding pregnancies and early development of the children. Results: The result

A minimum distance analysis of a certain class of two dimensional ISI channels

In this paper we perform a minimum distance analysis of a class of two dimensional intersymbol interference channels. In particular, some important cases of multitrack multihead magnetic recording systems fall into the studied class. Previously, Soljanin and Georghiades have studied the same problem as we do. The results derived in this paper are more conclusive and they improve upon theirs. The f

Survival of rats with N29 brain tumours after irradiation with 5 or 15 Gy and immunization with IFN-gamma secreting tumour cells

Intra cerebral tumours were inoculated into the brain of Fischer-344 syngeneic rats. After one week they were treated with either 5 or 15 Gy of Co-60-gamma radiation. The first immunization was given 1 hour before the radiation treatment and then two more times with 14-day intervals. Immunization was performed with 3 x 10(6) radiation sterilized IFN-gamma secreting tumour cells (N29) injected intr
