The solvent shift to the fluorescence transition pi* -> n in formaldehyde in aqueous Solution is theoretically analyzed. The solvent model has explicit representation of the solvent and uses the complete active space state interaction (CASSI) method to obtain a description of the wave function of the solute similar to what the complete active space self-consistent-field (CASSCF) method would give.
The introduction of guard channels in a cellular network is a method for giving priority to on-going calls by having channels exclusively reserved for handover purposes. Herein, an adaptive measurement-based dynamic guard channel scheme is introduced. The proposed scheme uses the number of on-going calls in adjacent cells and measurements of handover probabilities to determine the amount of guard
Phytase is an important enzyme in the food/feed industry. It catalyzes the hydrolysis of phytate, an anti-nutrient compound present in cereals and grains, to release orthophosphate and myo-inositol-6-phosphate with lower degrees of phosphorylation. Phytic acid is a strong chelator capable of complexing with a variety of metal ions under neutral and alkaline conditions, as well as with proteins and
The performance of truck drivers is crucial to the sustainability, in particular profitability, of motor carrier operations. Despite this, driver efficiency has received scarce attention in the transport and logistics literature. While the literature has focused on mathematical optimization, generic logistics frameworks and conceptual technology applications, measurement of drivers’ efficiency has
We consider a class of pseudodifferential evolution equations of the form u(t) + (n(u) + Lu)(x) = 0, in which L is a linear smoothing operator and n is at least quadratic near the origin; this class includes in particular the Whitham equation. A family of solitary-wave solutions is found using a constrained minimization principle and concentration-compactness methods for noncoercive functionals. T
Studies have shown that immigrants residing in Spain have lower risks of delivering low birthweight (LBW) and preterm babies despite their socioeconomic disadvantages (the healthy migrant paradox). However, less is known about other important perinatal outcomes derived from birth weight and gestational age such as macrosomia and post-term birth. This paper aims to compare the main indicators relat
In winter, small birds should be fat to avoid starvation and lean and agile to escape predators. This means that they face a tradeoff between the costs and benefits of carrying fat reserves. Every day they must gain enough fat to survive the coming night. Food-hoarding species can afford to carry less fat than nonhoarders because they can store energy outside the body. Furthermore, hoarders should
Decision support systems (DSS) have generated high expectations as a tool to support activated sludge operation because of their ability to represent heuristic reasoning and to handle large amounts of qualitative, uncertain and low-accuracy data. Previous applications have been satisfactory to control simple problems, when static reasoning and literature-based solutions were enough. However to fac
Personers reaktioner har studerats genom experimentella studier samt i genomgång av litteraturen. I denna undersökning har valet av utrymningsväg vid en simulerad brand studerats utifrån olika förutsättningar vad avser avstånd till utrymningsvägen och om dörren var öppen eller stängd. En andra del i försöket studerade hur personer reagerade och uppfattade situationen om en liten brand befann sig mHow people react on fire alarm have been studied in retrospect as well as in experiments. In the present study, the choice of exit was examined with respect to the distance to exits and open or closed emergency exit. The second part covers the question on how the subjects think and react in a situation having a small fire in the escape route. The third part deals with some communication aspects re
BACKGROUND: Patients with dental gold restorations are known to have a higher level of gold concentration in blood (B-Au). OBJECTIVES: To further investigate, in a study on patients with intracoronary stents and contact allergy to metals, the gold and nickel release from stainless steel stent with (Au stent) and without (Ni stent) gold plating. METHOD: A total of 460 patients treated with stenting
Society is becoming increasingly dynamic and complex, and therefore more vulnerable. It is thus important that society is resilient in order to be able to protect citizens and critical functions in the wake of disasters. It has been suggested that disaster risk reduction (DRR) is key in establishing resilience, and that adequate capacity in DRR is vital to reduce the effects of disasters. DRR and
Vasoconstriction accompanied by changes in skin color is a normal physiologic response to cold. The distinction between this normal physiology and Raynaud's phenomenon (RP) has yet to be well characterized. In anticipation of the 9th International Congress on Autoimmunity, a panel of 12 RP experts from 9 different institutes and four different countries were assembled for a Delphi exercise to esta
Some concerns still have not been resolved about the long-term safety of drug-eluting stents (DES) in patients with acute STEMI.
We sought to determine whether the COMT val158met polymorphism (rs4680) is associated with delusions and hallucinations in people with dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD). A total of 218 individuals, recruited from centres in Norway, Sweden and the UK were included in this study; 121 with clinically or neuropathologically diagnosed DLB/PDD and 97 age-matched, cog
This longitudinal study investigates the association between C-reactive protein (CRP), osteoporosis, fractures, and mortality in 1044 elderly women. CRP was not an indicator for low bone mineral density (BMD), bone loss, or fracture in elderly women; however, women with elevated CRP levels over a prolonged period lost more bone over the 10-year follow-up, although fracture risk was not increased.
