Beam dynamics of the ESS linac

The ESS linac will deliver an unprecedented 5 MW of average beam power when completed. Beyond the 90 MeV normal conducting front-end, the acceleration is performed using superconducting structures up to the design energy of 2 GeV. As the ESS will send the beam to a fixed tungsten target, the emittance is not as important a factor as in injectors. However, the losses have to be studied in detail, i

ESS commissioning plans

The ESS linac is currently under construction in Lund, Sweden, and once completed it will deliver an unprecedented 5 MW of average power. The ion source and LEBT commissioning starts in 2018 and will continue with the RFQ, MEBT and the frst DTL tank next year and up to the end of the fourth DTL tank in 2020. This paper will summarize the commissioning plans for the normal conducting linac with foc

QUAPEVA : Variable high gradient permanent magnet quadrupole

The magnetic and the mechanical design of a high and variable gradient Permanent Magnet Quadrupole (PMQ) is presented. Seven of them with various lengths, ranging from 26 mm up to 100 mm, for different integrated quadrupole strengths were manufactured. The measured magnetic performance of these devices is also reported. These devices were successfully commissioned to transport laser plasma acceler

5-hydroxytryptamine in the endocrine pancreas

The presence of serotonin (5-hydroxytryptamine [5-HT]) in pancreatic endocrine cells is well established. Nevertheless, recent advances are only now unraveling the signaling network involving 5-HT that partly regulates the release of hormones emanating from the islets of Langerhans. It is widely accepted that failure of the pancreatic β-cell to release sufficient amounts of insulin is the main cul

Serotonin and adipocyte function

The ability to store and mobilize energy is fundamental for physiologic function. Most excess energy is stored in adipose tissue as triglycerides, which is released as free fatty acids when needed through cellular processes tightly regulated by insulin. Intact adipose cell function is essential to regulate whole-body glucose and lipid metabolism. Several studies have focused on the metabolic impac

Investigation of mechanical and thermal loads in pcBN tooling during machining of Inconel 718

This study investigates machining superalloy Inconel 718 with polycrystalline cubic boron nitride (pcBN) tooling both numerically and experimentally. Particular attention is given to mechanical and thermal stresses in the cutting tool arising from segmented chip formation and associated forces and temperatures. The temperature dependence of the mechanical properties of pcBN has been investigated a

A 3D Universe? Students' and professors' perception of multidimensionality

This paper discusses the importance of learning to understand the three-dimensionality of astronomical objects, in particular nebulae. After collecting data from students' and professors' discernment of 3D we finds that this is difficult for both students and professors, which highlights the importance of addressing extrapolating three-dimensionality in astronomy education.

Familial malignant blood disease in the county of Jämtland, Sweden

In a material of 942 patients with malignant hematological disease, encompassing all diagnosed cases in the county of Jämtland in Sweden during a 22‐yr period, 36 families with multiple cases of such disease were found. Approximately 5% of the patients have at least one close relative who also suffers from a malignant hematological disease. An especially strong familial occurrence was found in the

The association between soft tissue sarcomas and exposure to phenoxyacetic acids. A new case‐referent study

A case‐referent study on soft tissue sarcomas (STS) was conducted, to see if previous findings regarding an association between exposure to phenoxyacetic acids or chlorophenols and this tumor type could be reproduced. Fifty‐five male STS patients were thereby compared with 220 living and 110 dead population‐based referents. Furthermore, another referent group consisting of 190 patients with anothe

The Role of PTEN Loss in Immune Escape, Melanoma Prognosis and Therapy Response

Checkpoint blockade therapies have changed the clinical management of metastatic melanoma patients considerably, showing survival benefits. Despite the clinical success, not all patients respond to treatment or they develop resistance. Although there are several treatment predictive biomarkers, understanding therapy resistance and the mechanisms of tumor immune evasion is crucial to increase the f
