Industry, War and Stalin’’s Battle for Resources: The Arctic and the Environment

為了解決Polar region的問題,作者Rowe, Lars 這樣論述:

In this book the territory of Pechenga, located well above the Arctic circle between Russia, Finland and Norway, holds the key to understanding the geopolitical situation of the Arctic today. With specific focus on the local nickel industry of the region, Lars Rowe explores the interaction betwee

n commercial and state security concerns in the Soviet Union. Through the lens of this local industry a larger historical context is unravelled - the nature of Soviet-Finnish relations after the Russian Revolution, Soviet international relations strategies during the Second World War and the nature

of the Stalinist economy in the early post-war years. By presenting this environmentally focused history of a small corner of the Arctic, Rowe offers the historical context needed to understand the current geopolitical climate of the Polar North.

再生礦物填充料類型與含量對密級配熱拌瀝青混凝土力學特性之影響

為了解決Polar region的問題,作者Tarekegn Kumala Sherre 這樣論述:

Investigation of recycled waste materials as a replacement of conventional filler is one alternative problem solving mechanism in hot mix asphalt (HMA). This study was designed to analyze the characteristics of two recycled fillers called hollow concrete block (HCB) powder and brick powder (BP), to

assess impacts of filler type and content on the mechanical and cracking properties of hot mix asphalt (HMA) at 3%, 5% and 7% as a full replacements for limestone (LS) filler. The recycled materials and limestone fillers obtained from construction and demolition wastes (CDW) site, and naturally min

ed for commercial uses, respectively. Filler characteristics were examined using different cutting-edge technologies, such as laser diffraction particle size analysis (LDS), Fourier transform infrared (FTIR), Brunauer, Emmette, and Teller method (BET), X-ray diffractometer (XRD), scanning electron m

icroscope (SEM) and energy dispersive x-ray spectroscopy (EDS). Rotational viscosity and dynamic rheological properties of asphalt mastic with recycled filler over a wide range of frequencies and temperatures have shown better values than the conventional filler. The respective effects of the recycl

ed fillers and the mechanical properties of the HMA mixtures were assessed by investigating superpave volumetric analysis, indirect tensile strength (ITS), moisture damage by tensile strength ratio (TSR), permanent deformation and indirect tensile cracking indices (IDTindex) tests. The analysis of t

he volumetric properties revealed that the 5% of each fillers content was considered as an optimum filler content in the mixtures among the three fillers percentages (3%, 5% and 7%). Thus, the mechanical properties had investigated at the optimum 5%, except for IDT crack tests that used three differ

ent % of fillers. The results demonstrated that mixture with the HCB powder recorded a 6% higher TSR value than the LS mixture and 7.2% higher TSR value than the BP mixture. Mixtures with the HCB powder significantly improved the moisture, rutting, and cracking resistance of the HMA, which are fact

ors critical to extend the life of asphalt concrete. In contrast, using BP results in mixed values and negative effects particularly in terms of moisture resistance and rutting. The filler concentrations had also significant effect on the cracking performance of the asphalt. Peak loads and fracture

energy were increased as filler percentages were increased from 3%, 5% to 7% while the cracking indices such as cracking tolerance index (CT-index), flexibility index (FI), fractural energy index (FEI), toughness index (TI), crack resistance index (CRI), and fracture strain tolerance ( FST) were gov

erned at the 5% filler concentration. Strong linear correlations were observed for the R2 values of 0.89, 0.85, 0.84 and 0.68 for the CT index, FI, FEI, and TI, respectively, while a moderate correlation with 0.52 R2 for CRI and a weak correlation with 0.44 R2 for FST were observed between both spec

imen diameters. Therefore, both of the specimen diameters examined in this study (100mm and 150mm) may use interchangeably to characterize the crack performance of HMA using the IDT test due to the test results found and discriminated low variability of cracking indices.

Seychelles

為了解決Polar region的問題,作者Mair, Lyn,Beckley, Lynnath 這樣論述:

This new sixth edition of Bradt's Seychelles has been fully updated and remains the only travel guide giving comprehensive information on the biodiversity of the islands and updates on the conservation efforts in an easy to read format (over 40% of the Seychelles land is under environmental protecti

on). New for this edition are expanded details of the many accommodation options, from F licit Island's luxurious resort and the many hotels recently refurbished to higher standards to the growing number of B&Bs and small guest houses that offer a more authentic Seychellois experience. New destinat

ion-specific places covered include the Outer Islands of Alphonse, Astove and Cosmoledo, and new practical information includes all the latest updates on getting around plus the significant increase in Marine Protected Areas.With plants and animals historically linked to Africa, Madagascar and Asia,

and marine life native to the tropical Indo-Pacific region, the Seychelles is a haven for those interested in natural history. The authors provide fascinating coverage of the islands' fauna and flora, from mangroves and turtles to birds and nature reserves. Updated throughout, they reveal the islan

ds many secrets from coco de mer palm forests and bird sanctuaries to local markets and Creole cuisine. This new edition not only provides up-to-date details of where to stay, eat and relax, but also where the to find the world's tiniest tree frog and how to visit Bird Islands to see the world's hea

viest Giant Tortoise.Beaches, snorkelling and diving among the coral reefs, wildlife, sailing, festivals, the UNESCO World Heritage Site of Vallee de Mai and hiking in the mountains... all are covered in Bradt's Seychelles, making it an ideal companion for a dream holiday. Lyn Mair is a naturalist

and travel guide who specializes in the islands of the western Indian Ocean, West Africa and Antarctica. Passionate about birdwatching, she regularly leads tours to exotic places and lectures on board ships plying the tropical waters off Africa and Polar regions. She was one of the first volunteers

to undertake environmental monitoring on Aldabra and has also spent many months travelling around the islands. Since her first visit in 1995 she has set foot on many of the most remote islands in the Seychelles.Lynnath Beckley is a professor of marine science at Murdoch University, Perth, Western A

ustralia and specialises in the Indian Ocean. She has undertaken scientific research, travelled and sailed extensively in the western Indian Ocean and has been writing for magazines, journals and books for many years.

北極海航道開通後對中國大陸之影響

為了解決Polar region的問題,作者黃引 這樣論述:

近年來,由於地球氣候暖化影響,使北極海融冰現象持續,進而使北極海航道通航及北極地區資源開發等議題成為討論重點。連接歐亞大陸的北極海航道的通航,除了直接影響環北極國家的軍事部署、經濟發展及政策推行外,近北極國家及非北極國家也將間接受到影響。因此,宣稱為近北極國家的中華人民共和國(以下簡稱為中共),當然迫切希望參與北極地區的資源開發及獲得北極海航道通航後之利益。所以,中共在2018年時正式公布《中國的北極政策》,便是希望透過政策的推行,能夠與北極國家共同擁有開發北極地區資源及使用北極海航道之利益。本文認為北極海航道的通航是中共參與北極地區治理的重要關鍵,在未來也將深深影響中共的國家發展。本研究發

現,北極海航道開通加上中共的北極政策推行,將可縮減航程與及增加貨運量、採多元路徑直接從極區運送天然能源及促進中國大陸東北地區區域發展;另外中共也因此面臨來自西方國家與俄羅斯的疑慮及本身條件受限等挑戰,須善用軍事外交與政治外交手段以因應。
