We report an observation of substantial deviations in the photoelectron angular distribution for photoionization of atoms in free Xe clusters compared to the case of photoionization of free atoms. The cross section, however, seems not to vary between the cluster and free atoms. This observation was made in the vicinity of the Xe 4d Cooper minimum, where the atomic angular distribution is known to
Photon energy dependent intensity variations are experimentally observed in the L2,3M2,3M2,3 Auger spectra of argon clusters. Two cluster sizes are examined in the present study. Extrinsic scattering effects, both elastic and inelastic, involving the photoelectron are discussed and suggested as the explanation of the variations in the Auger signal. The atoms in the first few coordination shells su
The free intracellular calcium ion concentration ([Ca2+]i) was measured simultaneously with isometric force in strips of guinea-pig mesotubarium using the Fura-2 technique. During the relaxed period (5-15 min) between spontaneous contractions [Ca2+]i continues to decrease after full mechanical relaxation to reach a minimal level of 86 +/- 8 nM (n = 9) just before the start of the next contraction.
Release of glycerol and free fatty acids (FFA) was investigated in human skeletal muscle strips. In the basal state, glycerol and FFA were released at almost equimolar rates (0.3 nmol/ng tissue.90 min). A nonselective beta-adrenoceptor agonist, isoprenaline, caused a concentration-dependent stimulation of glycerol release, whereas FFA release was unaffected. Basal and isoprenaline-induced glycerol
Transition metal dichalcogenide (TMDCs) monolayers make an excellent component in optoelectronic devices such as photodetectors and phototransistors. Selenide-based TMDCs, specifically molybdenum diselenide (MoSe2) monolayers with low defect densities, show much faster photoresponses compared to their sulfide counterpart. However, the typically low absorption of the atomically thin MoSe2 monolayer
Popular Abstract in Swedish Utvärdering av stråldos och bildkvalitet i mammografi Bröstcancer är den cancerform som är vanligast hos kvinnor. Genom tidig upptäckt med bröströntgen, mammografi, kan man behandla sjukdomen i ett tidigare stadium och därmed minska dödligheten. Det är också möjligt att behandla på ett skonsammare sätt vid tidig upptäckt. Därför har man startat hälsokontroller, screeniMammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. The side effects include a small and age related risk
Purpose:The purpose of this study is to map different kinds of tensions in product innovation and investigate how top managers use communication to shape subordinates' attention and thereby respond to these tensions.Design/methodology/approach:This study adopted an embedded case study of four innovation centers within a Nordic multinational firm.Findings:This study identifies three kinds of tensio

Osteoblasts, osteocytes, and osteoclasts (OCs) are involved in the bone production and resorption, which are crucial in bone homeostasis. OC hyperactivation plays a role in the exaggerated bone resorption of diseases such as osteoporosis, rheumatoid arthritis, and osteolytic tumor metastases. This work stems from the finding that OCs can express B7h (ICOS-Ligand), which is the ligand of the ICOS T
