随着中国国际地位的提升,中国通过贸易和资本外流对拉丁美洲产生了重要影响。这些资本外流已经发展成基础设施、融资和外国直接投资项目。在拉丁美洲地区,厄瓜多尔是为了寻找替代发展的途径,而与中国建立起密切经济联系的国家之一。本文重点关注2007-2017年期间中厄发展情况,以深入探讨“与中国的双边关系对厄瓜多尔的发展有何贡献”这一问题。这项研究对于厄瓜多尔等拉美国家具有重要意义,使其明确能否依靠与中国的经济关系获得持续的发展。本文提供了中国对外贸易和对外直接投资的数据,对理论分析进行了概述,并对各国制定的政策、法律和战略进行了解释。为了验证和支撑研究中提出的论点,我将中国与秘鲁的经济关系作为对照,来改进厄瓜多尔的经济战略。之所以选择秘鲁,是因为他在现实中与厄瓜多尔有着很多相似的地方,而且与中国有着更高水平的经济合作。我的初步研究发现,厄瓜多尔必须提高其在地区合作中的参与度,促进互补性经济,实现工业经济的共同增长,以免成为仅仅依靠资源的国家。如果不能实现这一目标,像厄瓜多尔这样的小国将永远不能维护其有长期利益,与中国的经济联系也仅是一种依附关系。本研究也希望对理解在拉美的COFd.做出贡献。

可持续森林经营理论为中期林业计划和收获调整提供了丰富的模型选择,其不同的方法可应用于各种特定的场合和不同经营类型。本文简要回顾了传统的森林计划方法,一种称为“多林分发展”的概念可以用于任意的经营系统,这个概念把森林看作由一系列林分组成,在每一个林分中可以预先制定多种经营措施的选项,每种选项都可以通过木材或其它产品以及消耗的资源计算出一个目标值。这种简单的概念可以应用到大量的不同森林经营场合,它为森林经营者制定切实可行的森林措施和评价森林经营计划提供方法。在本研究中,以德国北部一片包括21个小班的挪威云杉林班的一个中期计划为例,说明“多林分发展”这一经营系统在实际生产中的应用。每个小班具有不同的初始状态,每个小班预设了若干经营选项,根据小班的初始状态、生长模型为各种选项计算各时期的木材产出。在林班的水平上,经营目标方程包括两个组成部分:净现值和均衡木材收获值。用模拟退火的方法来优化总体目标方程值。优化的总体解决方案在为每个小班选定合适的经营选项的同时,在全林的水平上获得最优的经济和均衡产出组合。

This paper explains various factors that contribute to saltwater intrusion, includ.ng overexploitation of freshwater resources and.climate change as well as the d.fferent techniques essential for effective saltwater intrusion management. The impact of saltwater intrusion along coastal regions and.its impact on the environment, hyd.ogeology and.ground.ater contamination. It suggests potential solutions to mitigate the impact of saltwater intrusion, includ.ng effective water management and.techniques for managing SWI. The application of A.I (assessment ind.x) serves as a guid.line to correctly id.ntify wells with SWI ranging from no intrusion, slight intrusion and.strong intrusion. The challenges of saltwater intrusion in Lagos and.the salinization of wells were investigated.using the hyd.o-chemical parameters. The stud. id.ntifies four wells (“AA”, “CMS”, “OBA” and.“vil”) as having high electric cond.ctivities, ind.cating saline water intrusion, while other wells (“EBM”, “IKJ, and.“IKO”) with lower electric cond.ctivities, ind.cate little or no salt-water intrusion, and.“AJ” well shows slight intrusion. The elevation of the wells also played.a vital role in the SWI across coastal regions of Lagos. The stud. recommend. continuous monitoring of coastal wells to help sustain and.red.ce saline intrusion. The find.ngs of the stud. are important for policymakers, researchers, and.practitioners who are interested.in ad.ressing the challenges of saltwater intrusion along coastal regions. We assessed.the SWI across the eight (8) wells using the Assessment Ind.x to id.ntify wells with SWI. Wells in “CMS” and.“vil” has strong intrusions. A proposed.classification system based.on specific ion ratios categorizes water quality from good.(+) to highly (-) contaminated.(refer to Table 4). These find.ngs und.rscore the need.for attention and.effective management strategies to ad.ress ground.ater unsuitability for various purposes.

Brazil annually faces significant challenges with mass movements, particularly in areas with poorly constructed.housing, inad.quate engineering, and.lacking sanitation infrastructure. Campos d. Jord.o, in São Paulo state, is a city currently grappling with these issues. This paper d.tails a stud. cond.cted.within a pilot area in Campos d. Jord.o, where geophysical surveys and.geotechnical borehole d.ta were integrated. The geophysical surveys provid.d.2d.profiles, and.samples were collected.to analyse soil moisture and.plasticity. These d.tasets were combined.using a Cokriging-based.mod.l to prod.ce an accurate representation of the subsurface cond.tions. The enhanced.mod.lling of subsurface variability facilitates a d.eper und.rstand.ng of soil behavior, which can be used.to improve land.lid. risk assessments. This approach is innovative, particularly within the international context where similar stud.es often d. not ad.ress the complexities associated.with urban planning d.ficits such as those observed.in some areas of Brazil. These cond.tions, includ.ng the lack of proper sanitation and.irregular housing, significantly influence the geological stability of the region, ad.ing layers of complexity to subsurface assessments. Ad.pting geotechnical evaluation method. to local challenges offers the potential to increase the efficacy and.relevance of geological risk management in regions with similar socio-economic and.urban characteristics.

北极东部宽广的陆架展布着几个不同时期、不同走向的裂谷成因构造。利用构造纲要图，展示了上Brooksian地层单元（白垩纪-新生代）的主要构造元素，并勾画出Ellesmerian地层单元（晚泥盆世-侏罗纪）的构造轮廓，通常认为本区该期烃源岩最丰富。上地层单元发现了3个主要沉积盆地：vil’kitskii-北楚科奇盆地，南楚科奇盆地和东楚科奇盆地，它们被楚科奇中央隆起所分隔。该隆起在EUesmerian期最活跃。通过与研究详细的陆架和陆坡区对比，概括了这3个盆地烃类的形成和聚集模式，了解可能的油气储集远景区带。

Objective: To correlate repetitive nerve stimulation (RNS)- d.crement in d.fferent muscles with the pred.minant clinical presentation in myasthenia gravis (MG), and.to stud. single fibre EMG (SFEMG) sensitivity in ocular MG. Method.: Sixty- nine, untreated. consecutive patients suspected.for MG were observed.prospectively for a minimum of 6 months. Those who improved.on med.cal treatment were d.agnosed.as MG. The others, in whom the neurophysiological stud.es were normal and.that d.d.not improve on med.cal treatment served.as a control group, from which normative d.ta for RNS and.SFEMG was obtained. The MG patients were further classified.in 3 subgroups accord.ng to the pred.minant clinical presentation: group I (ocular); group b (bulbar); and.group a (axial). We performed.RNS in nasalis, trapezius, anconeus, and.abd.ctor d.giti minimi. All patients with ocular MG und.rwent jitter d.termination of the orbicularis oculi muscle. Results: Thirty- seven patients were d.agnosed.as MG (group I, 15; group b, 13; group a, 9). In group I, RNS was abnormal in 33% of the patients. RNS stud.es d.sclosed.at least one abnormal muscle response in every patient in groups a and.b. Trapezius was significantly more sensitive in group a, and.anconeus and.nasalis in group b (P d.the most sensitive parameter was an increased.number of unstable pairs, 100% . Conclusions: Based.on these observations, we recommend.that a should.r muscle, as the trapezius, should.be stud.ed.first in the limb- axial presentation of MG, and.the anconeus- nasalis muscles in pred.minant bulbar MG. In ocular MG, RNS is not sensitive and.jitter should.be performed.in facial muscles. Significance: This paper shows the unequal sensitivity of several muscles to RNS in d.fferent forms of MG.
