Irreversible Effects

The globe is presently reliant on natural resources, fossil fuels, and crude oil to support the world’s energy requirements. Human exploration for oil resources is always associated with irreversible effects. Primary sources of hydrocarbon pollution are instigated through oil exploration, extraction, and transportation in the Arctic region. To address the state of pollution, it is necessary to understand the mechanisms and processes of the bioremediation of hydrocarbons. The application of various microbial communities originated from the Arctic can provide a better interpretation on the mechanisms of specific microbes in the biodegradation process. The composition of oil and consequences of hydrocarbon pollutants to the various marine environments are also discussed in this paper. An overview of emerging trends on literature or research publications published in the last decade was compiled via bibliometric analysis in relation to the topic of interest, which is the microbial community present in the Arctic and Antarctic marine environments. This review also presents the hydrocarbon-degrading microbial community present in the Arctic, biodegradation metabolic pathways (enzymatic level), and capacity of microbial degradation from the perspective of metagenomics. The limitations are stated and recommendations are proposed for future research prospects on biodegradation of oil contaminants by microbial community at the low temperature regions of the Arctic.

Green Buildings are defined as environmental-friendly buildings aimed at minimizing the impact on the natural environment through a sustainable and efficient use of resources over their life-cycle. This is, perhaps, a recently-introduced building concept that is increasingly gaining attention due to the policies and strategies intended to reduce the carbon footprint of conventional buildings, which nowadays represent a large portion of the global energy consumption and C02 emissions. This study provides a systematic literature review of the existing body of knowledge of research related to Green Buildings in the arctic region. Despite numerous studies and projects developed during the last decades, a study describing the current research for this specific region is still missing. Starting from the definition of Green Building and Arctic Region, an examination is made of research approaches developed to achieve the required green building standards, for which rating tools currently in use for their evaluation are also identified. The result is a critical analysis highlighting benefits and critical issues of Green Buildings located in the Arctic in comparison with conventional buildings, focusing on the environmental, economic and social dimensions. Finally, future research opportunities are presented and discussed.

16S Rrna Pyrosequencing

We performed a bibliometric analysis of relevant research trends, based on academic articles about the aquatic microbial community and recorded in the Web of Science during 1991–2018. The number of publications per annum is clearly rising and began to grow rapidly in 2005. Developed countries (e.g.the USA and some European countries) published the most articles, and led international cooperation. International cooperation benefitted from the implementation of the European Union (EU) Water Framework Directive and from the origination and development of molecular biological techniques. A strong correlation existed among such key words as "bacteria", "DGGE" (Denaturing Gradient Gel Electrophoresis), "16S rRNA", "pyrosequencing" and "sediment" as key research directions for many years. Sediment, biofilm and wetland were the main habitats studied; and high-throughput sequencing gradually replaced the traditional DGGE and other technologies, remaining the most popular research method at present. Studies still focus on basic research; interest in microbial community composition, structure, diversity and ecology remains high; and metagenomics and the microbiome have received considerable attention recently. Key words such as "organic matter", "nutrient", "enzyme activity", "nitrification", "denitrification" and "cyanobacteria" indicate current research hotspots, and we suggest this is because increasing attention is paid to environmental protection and management of the water environment by aquatic microorganisms. We predict that future research will promote the ultimate goals of warning about threats to the water environment and restoration by investigating the function of the aquatic microbial community.

BACKGROUND Research on Graves’ ophthalmopathy(GO) increased remarkably in recent two decades, however, few studies provided statistical analysis to these publications. OBJECTIVE The purpose of this study is to detect and analyze the emerging trend and collaboration networks on GO. METHODS GO-related publications were collected from 1999 to 2019 from the Web of Science Core Collection Database. The publications were collected after restricting the publications with the category of article or review and language of English. The content of bibliometric analysis included changes in the annual number of publications, journals, authors, countries and institutions, keywords, and references. RESULTS There were 3051 publications collected which met the criterion. The number of annual publications had an increasing trend over the last 20 years. THYROID published 183 assays in total related to GO and ranked first. SMITH TJ had the largest number of publications on GO(83). The United States had the largest number of articles(784) and highest centrality(0.18) among the countries that had published essays related to GO. The UNIV PISA, which belonged to Italy, contributed 114 articles that are ahead of other institutions on the number of articles related to GO. The most recent burst keywords (proliferation, rituximab, and selenium) and references may provide clues on an emerging trend of research and clinical decision. CONCLUSIONS This bibliometric analysis highlight countries, institutions, and authors which contributed to the publications on GO. And the possible emerging trends on GO research extracted from burst keywords and references may provided the clues on clinical decision making and future research.

The Impact

The concept of Green Building refers to environmentally friendly constructions with the target of minimizing the impact on the natural environment through sustainable and efficient use of resources over their life cycle. Since modern buildings are large contributors to global energy consumption and greenhouse gas emissions, policies and international strategies intended to reduce the carbon footprint of conventional buildings are highlighting the role of this recently introduced building concept. This study provides a systematic literature review of existing research related to Green Buildings in the Arctic. Despite numerous studies and projects developed during the last decades, a study describing the current research status for this region is still missing. The review first examines the role that national and international policies developed by the arctic countries have on the development process of Green Buildings. Second, it provides an overview of the most commonly used and promoted Green Building rating systems used by the same countries in the region. The analysis highlights benefits and critical issues of Green Buildings located in the Arctic in comparison with conventional buildings, focusing on environmental, economic, and social dimensions. Finally, future research opportunities are presented and discussed.

The Bering Strait crossing would link the entirety of Eurasia to the entirety of the Americas. There are some immense geopolitical benefits of such project. It would bring about a deep and lasting change to global economic outlook. A possible tunnel under the Bering Strait and extension of the railroad network could open vast areas of Siberia containing mineral deposits necessary for global economic growth. According to a number of respectable Russian geologists, Siberia/the Arctic region is home to considerable amount of minerals and fossil fuels. The most valued function of the Bering Strait rail system would be to release those vast natural resources trapped underneath the tundra and permafrost for the benefit of Russia and the world. These resources can be used for global economic development. Moreover, the rail project would also build development corridors in the underdeveloped parts of Russian Siberia. The development of those resources in question and their rapid transportation to the global markets can contribute to overall development of Siberia. This paper will explore/evaluate the possible benefits of the Bering Strait crossing from Russian perspective and Russia’s new role in the Arctic region, under the frame of geopolitics.

Wind Source

In the last few decades, the relationship between energy production through fossil fuels and climate change has been widely discussed, which has led to a significant increase in studies on new forms of energy generation, using clean and renewable sources. Among these sources, wind power is considered as one of the most promising, since it has exponential growth, economicity and guarantee of continuous supply. Despite this, given that fossil sources are already consolidated, both in economic terms and in technical knowledge terms, it is necessary to know the competitiveness factors that can be characterized as potentialities or restrictions for the full development of the wind source. In order to know these aspects, the central objective of this research was to analyze the evolution path of the studies related to the competitiveness factors pertinent to wind energy, using bibliometric analysis so that future research directions can be identified. The results showed that studies on wind power and competitiveness have gained prominence since 2006, remaining constant until the current period. It was also found, through analysis by keywords and qualitative assessment of publications, that these surveys were classified into nine aspects related to competitiveness: Economic Analysis, Competition, Technology, Operational Costs, Regulation/Government, Environmental Impacts, Competitiveness, Market and Hybrid Generation, thereby providing guidance for future investigations.  Keywords: Wind Energy. Competitiveness. Renewable Energy. Bibliometric Analysis.

Biotechnological Potential

Polar microbiology remains as the most fascinating area of research which mainly focuses on exploration of psychrophilic organisms for having their cold-active enzymes of biotechnological potential. In this study, we have explored a culturable bacterial community and isolated 27 bacterial isolates with a different morphology from an unexplored site of Arctic region, for the possibility of identifying various active biomolecules. Screening of various isolates in a culture dependent manner helped us to identify strains capable of producing extracellular enzymes. The optimal growth parameters of most of the isolates are ranges between 18-22°C temperature, 3-5 days of incubation, 6-9 pH, and 3-5% (w/v) NaCl in LB media. It has also been found that among these isolates, 63% are able to produce lipase, 17% amylase, 7% xylanase and 7% isolates have responded for phosphatase activity but there are no isolates found for gelatinase and cellulase production ability. In addition, few isolates can also produce secretory protease, urease, β-galactosidase, etc. 16SrRNA gene sequence-based phylogeny revealed that the isolates belong to the genera of Psychrobacter, Planococcus, Halomonas, Arthrobacter, Oceanisphaera, Marinbacter, Pseudomonas, Algoriphagus. Strikingly, none of the Arctic isolates showed resistance towards commonly used antibiotics which indicates that the unexplored habitat is devoid of antibiotic exposure and so does the rise of antimicrobial resistance. The structure-function relationship of the isolated bioactive compounds from these isolates are the major focus of future research.
