Popular Abstract in Chinese 北极和亚北极地区对全球气候变化影响尤为重要。目前，北极地区正面临着变暖速度高于全球平均的现状。全球大约有50%的土壤碳储存在高纬度地区的土壤里，这些土壤碳主要分布于冻土层和泥炭层中。冻土层的解冻会使原先被冻结的土壤碳加速分解，产生温室气体，从而对全球变暖形成一个强烈的正反馈。与此同时，气温的增加可能会很大程度地影响植被在这些地区的生长和分布。动态生态系统模型是一种非常强大的工具，被用来研究气候变化对生态系统的影响，并且可以量化生态系统对大气的反馈信息。然而这些模型通常只关注大气、地表植被和土壤之间的水和碳的纵向转移，从而忽略了其在模型空间单元中的横向移动。这样可能会导致模型对于水和碳平衡的计算不够准确和全面，尤其在气候敏感的高纬度极地地区，这种偏差可能会更大。 本论文旨在解决动态生态系统模型中的这个局限性问题。基于目前最先进的动态生态The Arctic and Subarctic regions are of particular importance to the global climate change and are now experiencing a climate warming that is higher than the global average. Around 50% of the global soil carbon is stored in high latitude soils, especially in permafrost and peatland soils. Permafrost thawing, speeding up the decomposition of previously frozen soil carbon, is expected to result in s

Kampen mot fattigdom och socialt utanförskap är en av EU:s topprioriteringar efter den globala finanskrisen. Genom Europa 2020-strategin åtar sig unionen att lyfta minst 20 miljoner européer ur fattigdom. Utvecklingen i krisländerna har dock gått i motsatt riktning och de ekonomiska skillnaderna mellan EU:s medlemsstater fortsätter att öka. Är ett bestående välfärdsgap på väg att etablera sig mell

The German “Energiewende” (energy transition) is meant to be a contract between generations. The rebuilding of the whole energy system is designed and financed today in order to safeguard our children and grandchildren against fundamental risks: the enormous economic, social and environmental costs of a fossil-nuclear energy system, the risks of the nuclear fuel-cycle and the impacts of climate ch

The paper describes a simple analytical framework to be used when designing control algorithms for systems of specific type - in which the state derivatives go in feedback as accelerometer signals, and the overall controller explicitly exhibits an algebraic disturbance feedback loop. A simplified hydrofoil craft linear model is treated as an example. The method proposed combines all the approaches

Popular Abstract in Swedish Metylisotiazolinoner. Diagnostik och prevention av allergiska kontakteksem. Konserveringsmedel är biologiskt aktiva ämnen som hindrar mikroorganismer som t.ex bakterier och svampar att föröka sig. Produkter som innehåller vatten behöver konserveringsmedel, annars kan t ex konsistens, färg och lukt förändras så att produkten blir oanvändbar. Hudvårdsprodukter, rengöringPreservatives are biologically active substances which are required in water-based products/systems to prevent growth of micro-organisms. Kathon® CG (K-CG), one of several preservatives based on 5-chloro-2-methyl-4-isothiazolinon-3-one (MCI) and 2-methyl-4-isothiazolin-3-one (MI) has been shown to be a common sensitizer in dermatitis patients. The aims of the study were to find a method to demons
