It is well known that newly formed planetary systems undergo processes of orbital reconfiguration and planetary migration. As a result, planets or protoplanetary objects may accrete onto the central star, being fused and mixed into its external layers. If the accreted mass is sufficiently high and the star has a sufficiently thin convective envelope, such events may result in a modification of the

The aim of this study is to investigate the physical and chemical properties of particle emissions from candle burning in indoor air. Two representative types of tapered candies were studied during steady burn, sooting burn and smouldering (upon extinction) under controlled conditions in a walk-in stainless steel chamber. Steady burn emits relatively high number emissions of ultrafine particles do

G.fast is a new standard from the International Telecommunication Union, which targets 1 Gb/s over short copper loops using frequencies up to 212 MHz. This new technology requires accurate parametric cable models for simulation, design, and performance evaluation tests. Some existing copper cable models were designed for the very high speed digital subscriber line spectra, i.e., frequencies up to

1 alpha,25-Dihydroxyvitamin D-3 (1 alpha,25(OH)(2)D-3) had earlier been regarded as the only active hormone. The newly identified actions of 25-hydroxyvitamin D-3 (25(OH)D-3) and 24R,25-dihydroxyvitamin D-3 (24R,25(OH)(2)D-3) broadened the vitamin D-3 endocrine system, however, the current data are fragmented and a systematic understanding is lacking. Here we performed the first systematic study o

During flow testing of a deep, 1927-m, gravel packed screen completed well, it became apparent that well development was needed to increase productivity. A hydrojetting system using coiled tubing in combination with simultaneous pumping was developed and tested and found to be successful. To verify whether the jetting improved the well, the results of a pumping test conducted before and after the

Single top quark production via four-fermion contact interactions associated to flavour-changing neutral currents was searched for in data taken by the DELPHI detector at LEP2. The data were accumulated at centre-of-mass energies ranging from 189 to 209 GeV, with an integrated luminosity of 598.1 pb(-1). No evidence for a signal was found. Limits on the energy scale Lambda, were set for scalar-, v

Structural glass-timber composite beams and shear wall elements were investigated in terms of their mechanical behaviour, energy performance and their LCA performance. The load bearing components were manufactured using annealed float glass which was adhesively bonded to the timber with different adhesives. The results show, among other things, that is is possible to join the two materials glass a

Recent studies suggest that service definition is an ongoing process, with service characteristics being temporarily stabilised and destabilised through buyer–service provider interactions. However, little is still known about how and, in particular, why services are (re)defined during the sourcing process, e.g., in terms of their intended outputs, how they are performed (processes), the inputs re

Popular Abstract in English Parkinson’s disease (PD) is the second most common, after Alzheimer’s disease, neurodegenerative disease in man. Stiffness in joints, shaky hands, and slowness of movements make it difficult for people with PD to complete normal daily tasks like buttoning up a shirt. Additionally, PD affects memory, mood, sleep and the function of the gastro-intestinal tract. Over time,Parkinson’s disease (PD) is currently the second most common neurodegenerative disorder (after Alzheimer’s disease). PD is diagnosed on its motor symptoms, which include akinesia, bradykinesia, rigidity, postural imbalance and resting tremor. It is well established that the motor symptoms develop due to lack of dopamine in the striatum. This is caused by progressive degeneration of dopaminergic ne

This article examines ways of constructing research questions from existing literature, which are likely to promote the development of interesting and influential theories. We review 52 articles in organization studies and develop a typology of how researchers construct their research questions from existing literature. The most common way across paradigmatic camps is to spot various 'gaps' in the

We examined whether zinc transporter-8 autoantibodies (ZnT8A; arginine ZnT8-RA, tryptophan ZnT8-WA, and glutamine ZnT8-QA variants) differed between immigrant and Swedish patients due to different polymorphisms of SLC30A8, HLA-DQ, or both. Newly diagnosed autoimmune (≥1 islet autoantibody) T1D type 1 diabetic patients (n = 2,964,

Lund University Cardiopulmonary Assist System (LUCAS) is a mechanical device providing automatic 5 cm deep chest compressions and active decompressions back to normal anatomical position with a frequency of 100 per minute, and a duty cycle of 50%, i.e., LUCAS is constructed to give chest compressions according to the latest international guidelines in cardiopulmonary resuscitation (CPR). The aim

A set of single pass full penetration friction stir bead-on-plate and butt welds in HSLA-65 steel were produced using a range of traverse speeds (50 to 500 mm/min) and two tool materials (W-Re and PCBN). Part I described the influence of process and tool parameters on the microstructure in the weld region. This article focuses on the influence of these parameters on residual stress, but the presen

The ECL cells constitute the major endocrine cell population in the acid-producing part of the stomach. Gastrin from G cells in the antrum is the main stimulus of gastric acid secretion. Gastrin stimulates the ECL cells in the oxyntic mucosa to mobilize histamine, which in turn stimulates the parietal cells to produce hydrochloric acid. In the present study we assessed the usefulness and limitatio

In discussions of moral responsibility for collectively produced effects, it is not uncommon to assume that we have to abandon the view that causal involvement is a necessary condition for individual co-responsibility. In general, considerations of cases where there is "a mismatch between the wrong a group commits and the apparent causal contributions for which we can hold individuals responsible"
