The singularity cancelation scheme initially introduced by Khayat and Wilton for evaluating singular and near-singular potential integrals with 1/R singularities has in this paper been applied to parameterized quadrilateral cells containing higher order hierarchical H(div) Legendre basis functions. The singular and near-singular potential integrals treated in this paper appear in the method of mom
A statistical distribution for the number of CDMA RAKE fingers, N T, to be assigned in order to track a given percent of the total received power has been derived. The obtained distribution reveals a strong dependence of NT on the system bandwidth, the median RMS delay spread, its standard deviation and other environment specific parameters. Also, a statistical distribution for the fading width fw
From a combination of radiative lifetime measurements, performed with a time-resolved laser-induced fluorescence technique, for nine odd-parity levels of Ir I and four odd-parity levels of Ir II and branching fraction calculations, extended sets of transition probabilities have been derived for transitions of astrophysical interest. The new results are compared with the few experimental data avail
Single-layer molybdenum ditelluride (MoTe2) has attracted attention due to the smaller energy difference between the semiconducting (1H) and semimetallic (1T′) phases with respect to other two-dimensional transition metal dichalcogenides (TMDs). Understanding the phenomenon of polymorphism between these structural phases is of great fundamental and practical importance. In this paper, we report a
Despite the centrality of research phenomena, the process of their definition is often neglected and reduced to a simple choosing of pre-established subjects of interest. However, good research not only includes empirical work aimed at more or less ‘given as fact’ phenomena. It also involves phenomena construction: that is, the process of generating and establishing phenomena to investigate and th
The honeybee, Apis mellifera L. (Hymenoptera: Apidae), has recently become a model for studying brain asymmetry among invertebrates. A strong lateralization favouring the right antenna was discovered in odour learning and short-term memory recall experiments, and a lateral shift favouring the left antenna for long-term memory recall. Corresponding morphological asymmetries have been found in the d
Evaluating the subground properties during the initial stage of a construction of building is important in order to estimate the suitability of soil quality to the technical requirements of bearing capacity, resistance to stress, and strength. This study presented the evaluation of the geotechnical properties of soil intended for the construction of Max IV facility of Lund University, performed in

AIM: To explore HPs' perceptions of working on lifestyle management for patients with early rheumatoid arthritis (RA). METHODS: In this qualitative study, individual interviews were conducted with 20 HPs. Qualitative content analysis was used, and three categories and six subcategories were identified. RESULTS: HPs' perceptions of working on lifestyle management for patients with early RA revealed
Anthropogenically land cover modifications and human presence in natural environments are not without consequences to ecological processes. From a conservation perspective, these consequences are worrisome specially when considering the human domination of terrestrial ecosystems worldwide. The recent loss of wilderness areas has been described as catastrophic despite pro-active conservation scheme
Climate change mitigation requires rapid expansion of low-carbon electricity but there is a disagreement on whether available technologies such as renewables and nuclear power can be scaled up sufficiently fast. Here we analyze the diffusion of nuclear (from the 1960s), as well as wind and solar (from the 1980-90s) power. We show that all these technologies have been adopted in most large economie
Recycling polymers by site-specific scission into short-chain oligomers/polymers, followed by recoupling these to form the original polymer presents an energetically more favorable shorter-loop chemical recycling in comparison to recycling into monomers. Here, we present the synthesis and polymerization of triaromatic diesters to prepare polyesters with acylhydrazone units as weak structural links
