To cope with the immense complexity of the brain, neuroscientific research often focuses on isolated brain structures or circumscribed perceptual, cognitive or motor functions [1]. This reductionist approach overlooks the intricate and multifaceted interplay among various structural and functional *** instance, even simple movements require the coordinated activation of numerous neuronal populations across multiple brain regions [2].

Red-emitting Mn^(4+)-doped fluorides are a promising class of materials to improve the color rendering and luminous efficacy of white light-emitting diodes(w-LEDs).For w-LEDs,the luminescence quenching temperature is very important,but surprisingly no systematic research has been conducted to understand the mechanism for thermal quenching in Mn^(4+)-doped ***,concentration quenching of the Mn^(4+) luminescence can be an issue but detailed investigations are *** this work,we study thermal quenching and concentration quenching in Mn^(4+)-doped fluorides by measuring luminescence spectra and decay curves of K2TiF6:Mn^(4+) between 4 and 600 K and for Mn^(4+) concentrations from 0.01%to 15.7%.Temperature-dependent measurements on K2TiF6:Mn^(4+) and other Mn^(4+)-doped phosphors show that quenching occurs through thermally activated crossover between the ^(4)T_(2) excited state and ^(4)A_(2) ground *** quenching temperature can be optimized by designing host lattices in which Mn^(4+) has a high 4T2 state ***-dependent studies reveal that concentration quenching effects are limited in K_(2)TiF_(6):Mn^(4+)up to 5%Mn^(4+).This is important,as high Mn^(4+)concentrations are required for sufficient absorption of blue LED light in the parity-forbidden Mn^(4+)d–d *** even higher Mn^(4+) concentrations(>10%),the quantum efficiency decreases,mostly due to direct energy transfer to quenching sites(defects and impurity ions).Optimization of the synthesis to reduce quenchers is crucial for developing more efficient highly absorbing Mn^(4+) *** present systematic study provides detailed insights into temperature and concentration quenching of Mn^(4+) emission and can be used to realize superior narrow-band red Mn^(4+) phosphors for w-LEDs.

Reports from European university hospitals show an increase in work-related mental strain. Four European university hospitals started a comprehensive research program called Health and Organisation among University hospitals Physicians in Europe--the HOUPE Study in the year 2003. Based on the results from the HOUPE study, the authors conducted an intervention project together with HR-consultants at one of the participating hospitals. A collected cross-sectional survey in 2005 among permanently employed academic physicians （N = 1800, response rate 60%） at Karolinska University Hospital in Sweden. Results from the study were used in survey feedback seminars （N = 250）. This method is a way of systematic collection of data to process and give feedback to the organisation＇s members in order to initiate organisational change. By providing results based on the total sample, on each division, and unpublished data from each clinic the authors aimed to improve physicians＇ health and work satisfaction and thereby enhance the health of the physicians. Feedback seminars can arouse many emotions and might make people defensive. The role of resistance in the process of change is a paradox in that resistance slows down change. However, without resistance there will be no change at all. The authors conducted 20 feedback seminars of three hours duration where results were discussed relating mainly to the psychosocial work environment, psychological distress, and career paths, i.e., job demands, control at work, social interactions, leadership, commitment to the organisation, harassment at work, burnout, depression and suicide ideation. Altogether, 250 physicians participated in these meetings. To achieve acceptance for organisational change, data about relevant conditions in the organisation have to be processed in a systematic way in collaboration with all those who will benefit from changes, in concrete work units as divisions and clinics.

本试验的目的是开发从污染过的土壤中除去重金属的技术。试验是将六种不同的荷兰土壤用人工污染上五种不同的重金属,然后将污染过的土壤用三倍的0.1M的HCI溶液进行抽提,可将土壤中的Cu、Pb与Zn抽出90～99％,将Ni抽出80～90％,但是三价铬(Cr)只能抽出0～25％,可用次氯酸(HOCI)溶液在pH为8时抽出大部份铬(三价)。在水力旋流器中进行了固液分离试验。用化学凝聚与絮凝试验表明,几种絮凝剂都可收到很好的分离效果,这种絮凝并不影响抽提结果。在抽提与分离试验结果的基础上,安装了一套实验室规模的连续装置。抽提是在几只装有搅拌器的槽内进行,也可在有筛板的柱子中进行连续抽提。
