In this work, we numerically study a self-guiding process in which ionization plays a dominant role and analyze its effect on high-order harmonic generation (HHG) in gases. Although this type of self-guiding-termed "plasmacore- induced self-guiding" in previous works-limits the achievable cutoff by regulating the intensity of the laser beam, it provides favorable conditions for phase matching, whi

Equatorial volcanic eruptions are known to impact the atmospheric circulation on seasonal time scales through a strengthening of the stratospheric zonal winds followed by dynamic ocean-atmosphere coupling. This emerges as the positive phase of the North Atlantic Oscillation in the first 5 years after an eruption. In the North Atlantic, other modes of atmospheric circulation contribute to the clima

Graphite electrodes were modified with triangular (AuNTrs) or spherical (AuNPs) nanoparticles and further modified with fructose dehydrogenase (FDH). The present study reports the effect of the shape of these nanoparticles (NPs) on the catalytic current of immobilized FDH pointing out the different contributions on the mass transfer–limited and kinetically limited currents. The influence of the sh

In a low temperature district heating (LTDH) system the importance of well performing network and customer installations are essential due to reduced operation margins. The use of low-value waste heat in the production sets limitations on the supply temperature. New piping materials sets limitations on the supply temperature and the pressure level. All in all, this means an increased focus on ensu

Legionellae are bacteria that naturally exist in freshwater environments, but have also been found in seawater and soils. Legionella can cause illnesses such as Legionnaires' disease or Pontiac Fever where the Legionnaires' disease is a severe variant of Pneumonia and Pontiac Fever is a milder influenza like variant. Legionella bacteria can grow in domestic hot water systems (DHW systems) and in oLegionellae are bacteria that naturally exist in freshwater environments, but have also been found in seawater and soils.Legionellacan cause illnesses such as Legionnaires' disease or Pontiac Fever where the Legionnaires' disease is a severe variant of Pneumonia and Pontiac Fever is a milder influenza like variant.Legionellabacteria can grow in domestic hot water systems (DHW systems) and in order

”Bortom förnybart” är rapportens underrubrik men också en sammanfattning av en av de viktigaste slutsatserna från syntesarbetet. Fjärrvärmesverige har nästan uppnått sin vision om en fossilfri värmetillförsel. Detta är en fantastisk prestation som behöver ersättas av nya framtida miljö-, klimat- och samhällsmål att sträva efter. Framtida forskning kring fjärrvärme bör utgå från en tydligare vision

Tidigare svenska studier om prissättning och prismodeller i fjärrvärmeverksamhet har bidragit med viktiga aspekter ur ett produktionsperspektiv på hur man kan tänka vid utformning av prismodeller för fjärrvärme. Dessa studier har framförallt tryckt på att fjärrvärmens prismodeller bör återspegla fjärrvärmebolagets kostnader för produktion och distribution av fjärrvärme i kundledet då detta minskar

Duodenal perforation is a rare, but potentially life-threatening injury. Multiple etiologies are associated with duodenal perforations such as peptic ulcer disease, iatrogenic causes and trauma. Computed tomography with intravenous and oral contrast is the most valuable imaging technique to identify duodenal perforation. In some cases, surgical exploration may be necessary for diagnosis. Specific

Although extensively studied (and of large importance for food processing) there is still no general consensus on the time-dependent convective heat transfer coefficient (h) in immersion frying – reported values differ by orders of magnitude (4–7000 W m−2 K−1). Moreover, none of the many methods suggested have become a generally agreed upon standard. This study uses the general uncertainty managem

Lead-free halide double perovskites have gathered wide scientific interest since they are environmentally friendly and stable. However, compared to the lead perovskites, their optoelectronic properties are compromised. Herein we report a series of bulk lead-free mixed Bi-In halide double perovskites: Cs2AgBi1−xInxCl6 (0

In this paper, we study how increasing the cognitive demands of multitasking affects time preferences. The novelty of this paper is that it studied how time perception mediates the effect of multitasking on time preferences. Results from experimental psychology have demonstrated that people tend to experience the passage of time as quicker when they are busy with cognitively-demanding tasks. If ti

For over two hundred years, Egyptologists, archaeologists, explorers, knowledgeable enthusiasts, as well as intrepid tourists and laypeople alike have regarded Gebel el-Silsila as a minor archaeological site of little significance within the greater ancient scarred landscape of Egypt. For many, Gebel el-Silsila’s enduring and captivating sculptured stone landscape has been viewed merely from the d

Background and objectives: Despite global warming, the climate in Northern Europe is generally cold, and the large number of deaths due to non-optimal temperatures is likely due to cold temperatures. The aim of the current study is to investigate the association between cold temperatures and all-cause mortality, as well as cause-specific mortality, in Tallinn and Riga in North-Eastern Europe. Mate

BACKGROUND: There is growing evidence for a negative impact of traffic-related air pollution on risk of dementia. However, the contribution of noise exposure to this association has been rarely examined.OBJECTIVE: We aimed to investigate the individual and combined effect of noise and air pollution on risk of dementia.METHODS: Data on dementia incidence over a 15 year period was obtained from the

OBJECTIVES: There is highly suggestive evidence for an effect of air pollution exposure on dementia-related outcomes, but evidence is not yet present to clearly pinpoint which pollutants are the probable causal agents. The aims of this study was to assess the longitudinal association between exposures of fine ambient particulate matter (PM2.5) from residential wood burning, and vehicle exhaust, wi

This essay offers a contemporary overview of issues in organizational identity, organizational identification, difference, and branding, including references to personal experience, work trends, and popular culture. Along the way, we consider how certain intellectual traditions remain relevant today, as well as identify research exemplars for challenges to accustomed notions of identity in and aro

Objectives: Genetic variations in TNFAIP3 (A20) de-ubiquitinase (DUB) domain increase the risk of systemic lupus erythematosus (SLE) and rheumatoid arthritis. A20 is a negative regulator of NF-κB but the role of its DUB domain and related genetic variants remain unclear. We aimed to study the functional effects of A20 DUB-domain alterations in immune cells and understand its link to SLE pathogenes
