大自然并不会带护照

历史一再证明一个简单的事实：大自然并不会携带护照。雨降落在每个人和每样东西上，不管是下在富人还是穷人身上，或者下在强者还是弱者身上，都是同样的冷漠。

吴川—四会成矿带燕山期地球动力学背景——来自强过铝质花岗岩的制约

燕山期强过铝质侵入岩广泛出露于广东省吴川-四会成矿带。其岩石化学成分表现出Al2O3/TiO2比值较低的特征,暗示其源区熔融温度在875℃以上。它们的稀土元素分布型式指示其熔融源区的残留矿物组合中含有斜长石、石榴石和角闪石,表明岩浆形成于1.0～1.5GPa的压力条件下。据此推断,吴川-四会成矿带燕山期岩浆作用的能量主要来自底侵岩浆。

Importance and Role of Biodiversity and Tropical Forests in the Cultural, Socio-Economic and Religious Life of African Black People： Case of Benin

Biodiversity and tropical forests play a fundamental role in the life of the black people of Africa. In Benin, while some aspects of this role are well-documented, others are barely known. Moreover, these information remains so far very scattered through the literature which does not allow to have a global view on the contribution of biodiversity and forests to the life of people. In this work, it is presented the role of forests and biological diversity in the main vital areas of life of populations in south of Benin. The methodology used was based, with regard to the field, on bibliographical research, observation and/or field stakeholder survey. Investigations are more particularly focused on hardwood lumber uses and the species that are significantly used. The results highlight the uses that are made of vegetal elements of biological diversity and timber as forest products in south of Benin. The main areas explored are animist or traditional religion and traditional medicine, as well as socio-cultural and economic life. In this latter area, the most used timber species and their uses are identified; these include furniture, light carpentry, sculpture, formwork, canoe construction, drums and mortar making.

User Association and Wireless Backhaul Bandwidth Allocation for 5G Heterogeneous Networks in the Millimeter-Wave Band

The user association and wireless backhaul bandwidth allocation for a two-tier heterogeneous network （HetNet） in the mil- limeter wave （mmWave） band is proposed in this article. The two-tier HetNet is built up with a macro base station （MBS） and several small cell SBSs, where the MBS is assumed to be equipped with large-scale antenna arrays but the SBSs only have single-antenna capa- bility and they rely on the wireless link to the MBS for backhaul. The sum of logarithmic user rate, which is established according to the result of multi-user Multiple Input Mul- tiple Output （MIMO） downlink employing Zero-Force Beamforming （ZFBF）, is chosen as the network utility for the objective func- tion. And a distributed optimization algorithm based on primal and dual decomposition is used to jointly optimize the user association variable xj,z and the wireless backhaul band- width factor α. Simulation results reveal that the distributed optimization algorithm jointly optimizing two variables outperforms the con- ventional SINR-based user association strate- gies.

Association of Indian Ocean ITCZ Variations with the Arctic Oscillation during Boreal Winter

In this study,the authors analyzed the associations between the Arctic Oscillation(AO)and the tropical Indian Ocean(TIO)intertropical convergence zone(ITCZ)in boreal winter for the period 1979–2009.A statistically significant AO-TIO ITCZ linkage was found.The ITCZ vertical air motion is significantly associated with the AO,with upward(downward)air motion corresponding to the positive(negative)AO phase.The Arabian Sea anticyclone plays a crucial role in linking the AO and the TIO ITCZ.The Arabian Sea vorticity is strongly linked to high-latitude disturbances in conjunction with jet stream waveguide effects of disturbance trapping and energy dispersion.During positive(negative)AO years,the Arabian Sea anticyclone tends to be stronger(weaker).The mean vorticity over the Arabian Sea,averaged from 850hPa to 200 hPa,has a significant negative correlation with AO(r=0.63).The anomalous anticyclone over the Arabian Sea brings stronger northeastern winds,which enhance the ITCZ after crossing the equator and result in greater-than-normal precipitation and minimum outgoing long-wave radiation.

Spatial-temporal Characteristics of Land Use Intensity of Coastal Zone in China During 2000–2010

Based on remote sensing and GIS techniques, land use maps in 2000, 2005 and 2010 in China′s coastal zone were produced, and structural raster data of land use were further generated to calculate land use intensity comprehensive index(LUICI) for analyzing land use spatial-temporal characteristics at 1 km scale. Results show that: 1) from the perspective of spatial patterns of landforms at a macro scale, there is a significant difference in land use intensity between the north and the south of China′s coastal zone. Hotspots of changes mainly concentrated in metropolitan areas, estuaries and coastal wetlands; 2) elevation is an important factor that controlling land use spatial patterns at local scale. Land use intensity is much higher within areas below the elevation of 400 m and it decreased significantly as the elevation increasing; 3) there is a significant land-ocean gradient for land use intensity, which is low in island and near-shore areas, but high in the regions that 4–30 km far away the coastline because of much intensive human activities; however, in recent decades land use intensity had been promoted significantly in low near-shore area due to extensive sea reclamations; 4) significant differences of land use intensity were also found among provincial administrative units. A rising trend of land use intensity was found in provincial-level administrative units from 2000 to 2010. To sum up, elevation, land-ocean gradient, socio-economic status and policy are all influencing factors to the spatial patterns and temporal variations of land use intensity in China′s coastal zone.

Two Northward Jumps of the Summertime Western Pacific Subtropical High and Their Associations with the Tropical SST Anomalies

Based on the pentad mean ridgeline index of the western Pacific subtropical high (WPSH), the authors identified the two northward jumps of the WPSH from 1979 to 2008 and revealed their associations with the tropical SST anomalies. The authors show that the northward jumps, especially the second jump, exhibited remarkable interannual variability. In addition, the authors find that the two northward jumps were mutually independent and were influenced by the SST anomalies in the different regions of the tropical Pacific. The first jump was positively correlated with the SST anomalies in the tropical central Pacific from the preceding winter to June. In contrast, the second jump was positively related to ENSO in the preceding winter, but this correlation tended to weaken with the decay of ENSO and disappeared in July. Instead, a positive correlation was found in the Indian Ocean. We therefore suggest that ENSO plays an indirect role in the second jump through the capacitor effect of the Indian Ocean.

Relieving a Tropical Vernacular Habitat Typology as a Source for Contemporary Social Housing Designs

This work presents an analysis for the rural vernacular dwelling （Culata Yovai）, sited in the South America Guarani region, basin of Paraguay and Paraná rivers. Outdoor climate has conducted man to build along the time a habitat climatic responsive. Nowadays, studies in progress try to show how this vernacular typology can support new low-income house designs. The intent is to guarantee for new projects the socio-cultural image that people, coming from countryside to live in city outskirts, are accostumed. Also, to provide material improvements and functional adequation for a quality and healthiness. Natural ventilation is the main bioclimatic strategy during summer for thermal comfort, which influences the house characteristics. This is proven by calculation, and simulation with the CFX-ANSYS software. Thus, the analysis performed shows the real possibity to reconcile bioclimatism with the symbolic-cultural value represented by this vernacular architecture form. It is hopped that this study can be considered as a methodological contributition for new sustainable projects （materials, technics and services） of low-incoming houses in this Latin American region.

Identifying Links between Ecosystem Services and Aboriginal Well-Being and Livelihoods in North Australia： Applying the Millennium Ecosystem Assessment Framework

The livelihoods and well-being of Aboriginal and non-Aboriginal communities in remote and rural northern Australia are dependent upon the ecosystem services provided by tropical ecosystems. The well-being of all Australian citizens is measured by the Australia Bureau of Statistics （ABS） using socio-economic indicators. In this study we investigated the importance of non-market benefits derived from ecosystem services for Aboriginal well-being. Through a case study with the Mullunburra-Yidinji people in the Wet Tropics, Queensland, we applied the Millennium Ecosystem Assessment （MA） framework to identify the links between ecosystem services and the MA＇s six constituents of human well-being. The study demonstrated that cultural and provisioning services were key determinants of community well-being, and these are not currently measured by the ABS. We adapt the MA framework to include the ABS indicators and explore the potential strengths and weaknesses of the approach for measuring the well-being of contemporary remote and rural Aboriginal communities.

ASME Section Ⅲ Stress Analysis of a Heat Exchanger Tubesheet with a Misdrilled Hole and Irregular or Thin Ligaments

A stress analysis is described for a nuclear steam generator tubesheet with a thin, or irregular ligament, associated with a mis-drilled hole using the rules of ASME （American Society of Mechanical Engineers） B ＆ PV Section Ⅲ and non-mandatory Appendix A, Article A-8000 for stresses in perforated flat plates. The analysis demonstrates the proper application of the NB-3200 rules for this special application, with discussion of the differences between an actual tube hole deviation and what is assumed in ASME Appendix A. This is a companion paper to ＂Technical Justification Supporting Operation with a Tube Installed in a Mis-Drilled Hole of a Steam Generator Tubesheet＂.

Mitigating greenhouse gas of chemical fertilizer with farmland emissions through replacement organic manure in a temperate

Burning crop residues and excessive use of chemical fertilizers results in an enormous waste of bio- logical resources, which further weakens the potential capacity of the agro-ecosystem as a carbon sink. To explore the potential of farmlands acting as a carbon sink without yield losses, we conducted an experiment on a temperate eco-farm in eastern rural China. Crop residues were applied to cattle feed, and the composted cattle manure was returned to cropland with a winter wheat and maize rotation. Four different proportions of fertilizers were designed： 100 % cattle manure, 100 % mineral nitrogen, 75 % cattle manure plus 25 % mineral nitrogen, and 50 % cattle manure plus 50 % mineral nitrogen. Crop yield and greenhouse gas （GHG） emissions were carefully calculated according to the Intergovernmental Panel on Climate Change （IPCC） Guidelines for National Green- house Gas Inventories 2006. Our results showed that replacing chemical fertilizer with organic manure signifi- cantly decreased the emission of GHGs. Yields of wheat and corn also increased as the soil fertility was improved by the application of cattle manure. Totally replacing chemical fertilizer with organic manure decreased GHG emissions, which reversed the agriculture ecosystem from a carbon source （＋2.7 t CO_2-eq. hm-2 year-1） to a carbon sink （-8.8 t CO_2-eq. hm^-2 year^-1）. Our findings provide useful insights for improving agricultural ecosystems under global change scenarios.
