PHYLOGENY OF THE SINIPERCINE FISHES WITH SOME TAXONOMIC NOTES

Phylogeny of the sinipercine fishes, their relationships with some fossils and their systematic position were studied in this paper. Consisting of 2 sister groups, the sinipercine fishes were grouped as 2 genera - Coreoperca and Siniperca, while the genus Coreosiniperca was unwarranted for its type being a member in Siniperca, Having many special characters, Tungtingichthys was denied as the ancestor of the sinipercine fishes, however, Siniperca wusiangensis was taken as one member in Siniperca and some fossil percoids found in Japan had close relationship with sinipercine fishes. All characters of the sinipercine fishes are not concordant with that in Serranidae or Percichthyidae which leads to the conclusion that either the sinipercine fishes are not in Percichthyidae, or the defining characters of Percichthyidae listed by Gosline (1966) are wrong. But at present, we can only put the sinipercine fishes in Percichthyidae.

The Two Main Mechanisms of Glacier Lake Outburst Flood in Tibet,China

With the global warming,the disasters of Glacier Lake Outburst Flood(GLOF) have taken place frequently in Tibet in recent years and attracted more and more attention.A systematic survey was conducted on the 19 GLOFs in Tibet to study their two main mechanisms.Investigations indicated that all the events occurred in end-moraine lakes,and the outburst occurred partially and instantly.And the breach had the shape of an arc or a trapezoid in overflow outburst and its top width was 3-5 times more than the height.The two main mechanisms of GLOFs in Tibetan end-moraine Lake were overflow and piping,and the overflow mechanism caused by iceberg collapse was dominated in most cases.A formula was proposed to calculate the critical thickness of iceberg tongue that determines the collapse.Granular analysis of the moraine materials revealed that seepage deformation is crucial in the outburst process.Finally,we conducted a case study of the Guangxiecuo Lake to show its possible process of outburst and estimated the peak discharge of the resulted flood.

Marine Renewable Energy Seascape

Energy production based on fossil fuel reserves is largely responsible for carbon emissions, and hence global warming. The planet needs concerted action to reduce fossil fuel usage and to implement carbon mitigation measures. Ocean energy has huge potential, but there are major interdisciplinary problems to be overcome regarding technology, cost reduction, investment, environmental impact, governance, and so forth. This article briefly reviews ocean energy production from offshore wind, tidal stream, ocean current, tidal range, wave, thermal, salinity gradients, and biomass sources. Future areas of research and development are outlined that could make exploitation of the marine renewable energy （MRE） seascape a viable proposition; these areas include energy storage, advanced materials, robotics, and informatics. The article concludes with a sustainability perspective on the MRE seascape encompassing ethics, leg- islation, the regulatory environment, governance and consenting, economic, social, and environmental constraints. A new generation of engineers is needed with the ingenuity and spirit of adventure to meet the global challenge posed by MRE.

Variation of Air-Sea Heat Fluxes over the Western Pacific Warm Pool Area and Its Relationship with the South China Sea Summer Monsoon Onset

Based on oceanic and atmospheric parameters retrieved by satellite remote sensing using a neural network method, air-sea heat fluxes over the western Pacific warm pool area were calculated with the advanced the advanced Coupled Ocean-Atmosphere Response Experiment 3.0 (COARE3.0) bulk algorithm method. Then, the average annual and interannual characteristics of these fluxes were analyzed. The rela- tionship between the fluxes and the South China Sea (SCS) summer monsoon onset is highlighted. The results indicate that these fluxes have clear temporal and spatial characteristics. The sensible heat flux is at its maximum in the Kuroshio area, while the latent heat flux is at its maximum in the North Equatorial Current and Kuroshio area. The distribution of average annual air-sea heat fluxes shows that both sensible and latent heat fluxes are maximized in winter and minimized in summer. The air-sea heat fluxes have obvious interannual variations. Correlation analysis indicates a close lag-correlation between air-sea heat fluxes in the western Pacific warm pool area and at the SCS summer monsoon onset. The lagcorrelation can therefore predict the SCS summer monsoon onset, providing a reference for the study of precipitation related to the monsoon.

Raising the Stake of Global Warming and Climate Change in Nigeria Media： Implications for Development

The elements that mid-wife news and editorial contents remain： what, who, where, when, why, and how, typical of Lasswell＇s （1948） conceptual model of communication. The operational actualization of this in theory and practice exemplifies a paradigm of news and other editorial contents reporting slant that pays more attention to dramatizing events and incidents, at best exacerbating, psychologically, panic, apprehension, and tension, but hardly focusing on solution to critical situation in society. However, journalism may not always be about the curses; it could be about cures, particularly in regard to climate change/global warming issues in developing economies like Africa＇s. Hence, the thrust of this paper is a strong advocacy for curative journalism that should issue from a well fed body of science-based information on how to adapt to the menace of global warming palaver in developing nations of the world, especially Nigeria. It advances that new media scientific journalism that could benefit society should do more of probing solution rather than concentrate on the throes： the former acting as an anti-depressant journalism instead of a hopeless journalism.

Small-Scale Household Biogas Digesters as a Viable Option for Energy Recovery and Global Warming Mitigation--Vietnam Case Study

Biogas from livestock waste is considered as clean and renewable energy in Vietnam. In the last 20 years, in rural and remote areas of Vietnam, there has been a significant increase of small-scale household biogas digesters. Biogas digesters create the benefits of replacing energy and mitigation of climate change caused by greenhouse gas （GHG） emission and deforestation for firewood and charcoal. Livestock waste produces approximately 85 million tonnes every year and continues to increase, meaning there are huge feedstocks for biogas digesters to meet the energy demands in households. However, there are also many constraints on the development programme for small-scale household biogas digester. In Vietnam, the socio-economic situation and the lack of a sustainable energy policy for biogas from livestock sector are hindering the growth of the biogas digester industry. Government subsidies are needed to encourage farmers to participate. This paper will be helpful not only for the sustainable development of household biogas in Vietnam, but also for the developing program of biogas generation in developing countries with similar agricultural economies to Vietnam.

WZ Sagittae Space WeathermGIobal Warming

The planet responds thermally to the impacts of nova WZ Sagittae debris by heating and cooling. The result in the first 19 years of the nova WZ Sagittae cycle is global warming that is hemi-spherically dependent and is detectable in South America ice core data and Antarctica surface mass balance data. Planetary thermal data are correlated in the past by calculating the debris impact times from the super outbursts times of nova WZ Sagittae. The shape of the arctic ice cap is dependent on the 220 degree path of the debris and does not exist southward between the western extension and eastern termini of nova WZ Sagittae that define the Arctic heating path. Future global heating from nova WZ Sagittae will begin in 2020-2021. The increase of 6 to 8 magnitude unusual earthquakes in recent years is the results of nova WZ Sagittae and SN 1054 debris impact. Unusual occurrences in the biosphere indicate the starting time of impacting supernova debris streams. The Antarctic sea ice distribution in November of 2016 defines the termini of maximum particle concentration impact from supernova 1006 in the southern hemisphere. The killing heat in India of the northern hemisphere is associated with the western terminus of this supernova. Novas and supernovas times of impact correlate with plague outbreaks in the western USA marking the particles in the debris streams as the cause of the disease.

Analysis on the Hotel Management Mode from the Perspective of Low-carbon Tourism

As the global warming is becoming more and more serious, people have gradually come to realize the important role of low- carbon life. Since a strategy of sustainable development was proposed in China, the concept of low-carbon tourism has emerged, requiring tourists to carry out energy conservation and environmental protection as much as possible in the process of travel. The hotels in scenic areas naturally become an important part of tourists in travel and play a crucial role in the development of low-carbon tourism. Therefore, a deep analysis on the present hotel management mode is necessary, promoting hotels to conform to the requirements of low-carbon tourism. In this paper, hotel management is discussed from the perspective of low-carbon tourism, so as to provide ideas of practical significance and guiding role and a basis for the future low-carbon tourism and hotel management.

Impact of Climatic Change on Agricultural Production and Response Strategies in China

A number of studies indicate that global climate warming has been increasing, especially in recent decades. Climate warming greatly affects global agro-production and food security-- becoming a hotspot of global environmental change. This paper proposes a structural and orientational framework for scientifically addressing climatic change impact on agroroduction. Through literature reviews and comparative studies, the paper systematically summarizes influencing mechanisms and impact of climate warming on such agro-production factors as light, temperature, soil quality and water environment. The impact of climate warm- ing on cultivation regions, cropping systems, crop pests, agro- production capacity, agro-economy and farm management is analyzed. Then, suitable climate-adapting agro-development strategies are put forward for different regions in China. The strategies are carefully selected from a repository of international tested climatic change countermeasures in agriculture at national or district level.

Widening and weakening of the Hadley circulation under global warming

The Hadley circulation is one of the most important atmospheric circulations.Widening of the Hadley circulation has drawn extensive studies in the past decade.The key concern is that widening of the Hadley circulation would cause poleward shift of the subtropical dry zone.Various metrics have been applied to measure the widening of the tropics.What are responsible for the observed widening trends of the Hadley circulation? How anthropogenic and natural forcings caused the widening? How the widening results in regional climatic effects? These are the major questions in studing the widening of the Hadley circulation.While both observations and simulations all show widening of the Hadley circulation in the past few decades,there are no general agreements of changes in the strength of the Hadley circulation.Although some reanalysis datasets show strengthening of the Hadley circulation,it was shown that the strengthening trend could be artificial,and simulations show weakening of the Hadley circulation for global greenhouse warming.In the present paper,we shall briefly review the major progresses of studies in trends in width and strength of the Hadley circulation.We address answers to these questions,clarify inconsistent results,and propose ideas for future studies.

Characteristic of Local Boiling Heat Transfer of Ammonia and Ammonia/Water Binary Mixture on the Plate Type Evaporator

Power generation using small temperature difference such as ocean thermal energy conversion(OTEC)and discharged thermal energy conversion(DTEC)is expected to be the countermeasures against global warming problem.As ammonia and ammonia/water are used in evaporators for OTEC and DTEC as working fluids,the research of their local boiling heat transfer is important for improvement of the power generation efficiency.Measurements of local boiling heat transfer coefficients were performed for ammonia/water mixture(z=0.9-1)on a vertical flat plate heat exchanger in a range of mass flux(7.5-15 kg/m2s),heat flux(15-23 kW/m 2),and pressure(0.7-0.9 MPa).The result shows that in the case of ammonia/water mixture,the local heat transfer coefficients increase with an increase of mass flux and composition of ammonia,and decrease with an increase of heat flux.

Model study of relationship between local temperature and artificial heat release

In recent decades,it presents a more obvious temperature rise in urban area along with the global warming.City is generally the center of human society,so the study on urban temperature variation will be helpful to our city development planning that is to reduce urban warming.The study is also helpful to a more comprehensive understanding of the causes of climate warming,which could provide a theoretical support to the government to make more reasonable international energy policies.Local temperature rise has different mechanisms with the global warming:large quantities of artificial heat release from the energy consumption will stay in urban areas for a period of time,which will inevitably influence the short-term trend of the local temperature change.Based on that view,a structural thermodynamic model was established in this paper to investigate the effect of the artificial heat release on the urban local temperatures.In the model,the city environment was divided into Human,Local,Outer three blocks,and then the heat and temperatures of the blocks were analyzed based on the laws of thermodynamics.After that,the effect of artificial heat release in Human block on the local temperatures was clarified.The model shows that the artificial heat release has an approximately linearly promoting effect on the local temperature rise,and the more the heat release is,the stronger the effect is.In addition,a validation of that model was carried out based on some national statistical data.The data of temperatures and artificial heat release of some provincial capitals of China were analyzed with linear regression extrapolation method and Pearson correlation statistical method.The results show that in most capital cities,the temperature variations basically depend on the artificial heat release in a linear relationship,which usually becomes more apparent with the increase of the artificial heat release in both spatial and temporal dimensions.The conclusions of the statistics have good conformity with the model and the rationality of the model is verified.

Virtual design and analysis with multi-dimension coupling for engineering machinery cooling system

A good cooling circle should ensure that the system can work at an appropriate temperature in the requirements of power increase,engine compartment constraint and working demands for modern engineering machinery,which asks for a thorough understanding of system thermal loads before practical production.However,traditional experiment method spends a long time,costs a huge resource but lacks efficiency,whereas virtual design can avoid the shortcomings of traditional method and can analyze operating states adequately with variable loads on engine,generator,drives,battery pack and HVAC systems.Therefore,this paper focuses on a new virtual design method based on multi-dimension coupled simulation adopting Flowmaster software for initial prediction and CFX tool for further optimization.The simulation results in different operating conditions are compared and validated with experiments.Orthogonal experiment and range analysis are used to explore key parameters of cooling system.The research will be helpful in guiding future design and optimization of engineering machinery.

The behavior of deep convective clouds over the warm pool and connection to the Walker circulation

As the deep convective clouds(DCCs) over the western Pacific and Indian Ocean warm pool may play different roles in the climate system, variations in DCC properties over these two sectors are investigated and compared. The DCC intensity and area varies more significantly in the Indian Ocean than the western Pacific sector, while the DCC frequency is comparable in both sectors at the seasonal scale. Although the Indian Ocean sector is strongly dominated by the seasonal evolution, the interannual variations in the two sectors are comparable for all three DCC properties(frequency, intensity, and area). Besides,Walker circulation is closely correlated with the interannual variability of DCCs in both sectors. The Walker circulation strengthens(weakens) as the DCCs shift eastward(westward) over the Indian Ocean sector and westward(eastward) over the western Pacific sector. When more or stronger DCCs occur over the Indian Ocean sector(western Pacific sector), the Walker circulation becomes stronger(weaker) and shifts westward(eastward). Interestingly, the response of the Walker circulation to DCC variability over the warm pool is asymmetry. The asymmetry response of the Walker circulation to the negative and positive DCC anomaly may be related to the non-linearity internal variability of the atmosphere. DCCs over the Indian Ocean sector have a much weaker nonlinear correlation with the Walker circulation than DCCs over the western Pacific sector.
