FOB、CIF、CFR与FCA、CIP、CPT价格术语应用与案例分析

FOB、CIF、CFR与FCA、CIP、CPT价格术语在运输方式、风险转移点、提单签发人、时间、地点、性质及运费计收、保险区段、运输合同订立等方面存在差异,国际商会自上世纪20年代起即不断对有关价格术语进行研究和解释.但由于国际贸易、运输的发展,人们对新、老价格术语中买卖双方的风险转移、责任、费用的划分时常难以理解.本文中作者试通过案例分析说明之.     

Synoptic transects on the distribution of trace elements (Hg,Pb, Cd,Cu, Ni,Zn, Co,Mn, Fe,and Al) in surface waters of the Northern- and Southern East Atlantic

Surface seawater samples were taken in the framework of the GEOTRACES program on “POLARSTERN” expedition ANT XXIII/1 in the Eastern Atlantic in 2005 to study the distribution of the trace elements Hg (mercury), Pb (lead), Cd (cadmium), Cu (copper), Ni (nickel), Zn (zinc), Co (cobalt), Mn (manganese), Fe (iron), and Al (aluminium). With the exception of Hg, results were compared to earlier datasets from 1989 to 1990. The particulate fraction averaged over the transect was calculated to be 49% for Cd, 23% for Mn and 50% for Fe indicating a release of these TEI's (trace elements and their isotopes) from a leachable SPM fraction in the stored and acidified samples.Total Pb concentrations ranged between 5 and 20 pmol kg^? 1 in 2005 with highest values in the ITCZ (intertropical convergence zone). In 1989 Pb concentrations were twice as high in the region of the ITCZ, while by a factor of 10–15 higher values were obtained in the North Atlantic.Total Cd and Co are dominated, by different seasonal upwelling regimes (Equatorial upwelling, Guinea Dome, Angola Dome).Total Cu, Ni, Fe, Mn and Al show nearly identical concentrations in 1990 and 2005. For total manganese and aluminium strong maxima (3–4 nmol kg^? 1 and 55 nmol kg^? 1 respectively) are observed between 23°N and 0°, while the Fe maximum (6–9 nmol kg^? 1) is located at 7°N. Total Hg concentrations ranged between 0.5 and 4.5 pmol kg^? 1.     

美国航空母舰之六十五 CVN-77“乔治·布什”号

CVN-77“乔治·布什”号航空母舰是美国海军“尼米兹”级超级航母的第十艘，也是该纫的最后一艘，是美国海军第十一艘核动力航空母舰，也是美国海军中第一艘以“布什”（美国第41任总统，现任总统小布什之父）命名的战舰。据称，CVN-77之所以以老布什的名字命名，不仅是因为他曾任美国总统，曾领导美国打赢了1991年的海湾战争，而且缘于他与美国海军及航母有很深的渊源：早在1942年，18岁的布什就参加了美国海军并于次年成为一名舰载机飞行员，     

球扁钢等效方法的研究

在进行船体结构强度的计算分析时,需要将球扁钢等效为L型材或T型材进行屈服及屈曲计算。然而,现有的等效转化方法存在较为明显的问题。本文在前人研究基础上,推出两种简化等效方法,并与现有方法进行计算对比,结果表明这两种方法简单方便,精确度高。此外,本文分别使用三种转化方法,运用Mars2000软件计算某船剖面的极限强度。计算结果表明,使用本文提出的等效转化方法一计算船体结构极限强度最合理。     

Congress,reform, and oceans policy

Congress has not been able to pass comprehensive oceans policy legislation in recent years. Nonetheless, significant individual oceans policy measures have been enacted. These are reviewed in the article. A Joint Committee on the Organization of Congress has been established to recommend reforms in how Congress conducts its business, including proposals for committee restructuring. These proposals could affect how Congress examines oceans policy issues, but it is unlikely that these reforms will make it easier to pass comprehensive oceans policy legislation. For this to happen, well‐organized constituencies have to demonstrate support for this legislation, which has not happened to date.

Culture,Ethnography, and Marine Affairs

Abstract

Marine and coastal zone policy represents a collaboration of people managing and people managed. This paper takes a holistic stance in suggesting that marine communities are viewed properly as networks of focused interest groups, policymakers, professionals, and publics. The interplay between culture and marine and coastal policy is appropriately one topic of applied social research. Seven ethnographic studies in this domain are introduced in this theme issue and help us to understand sociocultural processes and institutions bearing on marine affairs.

Containerization, inter-port competition, and port selection

This paper explores the criteria shippers employ in the port selection process. By focusing on the containerized traffic between the North American Mid-West and Western Europe, the factors considered by exporters and freight forwarders are examined. The findings suggest that decision-makers are influenced more by price and service considerations of land and ocean carriers than by perceived differences in the ports of entry and exit. Port infrastructures do not appear to play an important role in the routeing decisions made by an important group of independent businesses involved in the North Atlantic container trade.     

Monitoring trace elements (Al, As, Cr, Cu, Fe, Mn, Ni and Zn) in deep and surface waters of the estuary of the Nerbioi-Ibaizabal River (Bay of Biscay, Basque Country)

Deep water samples (in contact with the sediment) were collected at eight different points of the estuary of the Nerbioi-Ibaizabal River (Bay of Biscay, Basque Country), both at low and high tides, during four sampling campaigns (May, September and December 2005 and March 2006). Superficial water was also sampled in March 2006. Temperature, pH, redox potential, dissolved oxygen and electrical conductivity corresponding to each sample were measured in situ at each sampling point using a multiparametric probe. The physico-chemical parameters found are typical of highly stratified estuaries, with an acceptable oxygenation level. After filtering and acidifying the samples, they were analysed by inductively coupled plasma/mass spectrometry (ICP/MS) to simultaneously determine the total concentration of Al, As, Cr, Cu, Fe, Mn, Ni and Zn. Concentrations in the μg kg^− 1 level were found in all cases (c_Cr and c_Ni, 1–10; c_Al, c_As and c_Zn, 10–50; c_Cu and c_Mn, 10–100 and c_Fe, 100–400 μg kg^− 1). A probable net input of Al, Cr, Mn and Zn via the main (Nerbioi-Ibaizabal) and some of the tributary rivers (Galindo, Asua and Gobela) was identified. Evidence of a common source of Al and Zn to the estuary was found. Correlation analysis of data revealed connections between variables (concentration of Cu, Fe and As with salinity, as well as c_Al with c_Zn, c_Cu with c_Fe, c_As with c_Fe, and c_As with c_Cu). Principal Component Analysis (PCA) of data allowed the samples to be grouped according to sampling campaign, with two principal components accounting for 62% of the total variance. In addition, plots of element concentration against salinity suggested a conservative behaviour for As, Cu and Fe and a non-conservative one for Cr. Not clear mixing behaviour was observed for the rest of elements.     

Sediment geochemistry and mineralogy in Milos bay, SW Kyklades, Aegean Sea, Greece

This work aims at studying the geochemistry and mineralogy of Milos bay surface sediments. The bay forms an enclosed marine area, supplied totally by volcanic formations. Totally 16 samples were subjected to sedimentological (grain size), mineralogical (microscope examination and X-ray diffraction of the bulk sample and the pelitic fraction), and geochemical analyses (X-ray fluorescence in the pelitic fraction). Also the carbonate content was determined. Sediments were sandy with a high carbonate content (14–58%). The dominant minerals recognized in the pelitic fraction were smectite, kaolinite and illite, followed by chlorite, quartz, calcite, Mg-calcite and feldspars. In general, element concentrations appeared to be within the normal range, except Pb and Zn, which exhibited relatively high values. The Index of Geoaccumulation I_geo was computed, in order to investigate a possible enrichment of the surface sediments in metals. The analysis revealed again high values of I_geo class for both Pb and Zn. A careful study of the area, in relation to the quality of the catchment basins petrology, lead to a non-anthropogenic origin of these high concentrations. The enrichment of the surface sediments in Pb and Zn is attributed to the weathering of several mineral deposits, pyroclastic rocks and lavas, covering almost all Milos vicinity. A study of the geochemical data correlation coefficient matrix revealed three major groups of elements: (i) the elements of detrital origin represented by Si, Al, K and a part of the metals; (ii) the carbonates group; and (iii) a Fe–Mn oxyhydroxides–oxides group, which attracts a part of Pb, Cr and Ni.
