Development of a real-time PCR assay(SYBR Green I) for rapid identification and quantification of scyphomedusae Aurelia sp.1 planulae

The complicated life cycle ofAurelia spp., comprising benthic asexually-reproducing polyps and sexually-reproducing medusae, makes it hard for researchers to identify and track them, especially for early stage individuals, such as planulae. To solve this problem, we developed a real-time PCR assay （SYBR Green I） to identify planulae in both cultured and natural seawater samples. Species-specific primers targeting Aurelia sp.1 mitochondrial 16S rDNA （mr 16S rDNA） regions were designed. Using a calibration curve constructed with plasmids containing the Aurelia sp. 1 mt 16S rDNA fragment and a standard curve for planulae, the absolute number of mt 16S rDNA copies per planula was determined and from that the total number ofplanulae per sample was estimated. For the field samples, a 100-fold dilution of the sample DNA combined with a final concentration of 0.2 μg/μL BSA in the PCR reaction mixture was used to remove real- time PCR inhibitors. Samples collected in Jiaozhou Bay from July to September 2012 were subsequently analyzed using this assay. Peak Aurelia sp.1 planula abundance occurred in July 2012 at stations near Hongdao Island and Qingdao offshore; abundances were very low in August and September. The real-time PCR assay （SYBR Green I） developed here negates the need for traditional microscopic identification, which is laborious and time-consuming, and can detect and quantify jellyfish planulae in field plankton samples rapidly and specifically.

Dynamic development characteristics of amounts of gas and levels of pressure in the Pan-1 coal mine of Huainan

The Pan-1 coal mine located in Huainan municipality, Anhui province, is abundant in coal resources. In order to discover the natural conditions of gas in its coal seams, we inverted the burial history of these coal seams using the software of Easy%Ro method and simulated the development process of gas volumes and pressure of the major coal seams using CBM History Simulation Software. Our analysis shows that the devolution of gas volumes and levels of pressure can be divided into four stages: i.e., a biogas stage (P1-P3), a pyrolysis gas stage (T1-T2), an active gas enrichment stage (T3-K1) and a gas dissipating stage (K2-present). Currently, the average amounts of gas and gas pressure in coal seams Nos. 13-1, 11-2 and 8 of the Pan-1 coal mine are 8.18 m3/t and 2.20 MPa; 3.89 m3/t and 2.47 MPa and 6.35 m3/t and 2.89 MPa, respectively. This agrees very well with current mining data.

A model of quality control based on recycling economy and sustainable manufacture

People currentiy pay attention to a hotspot problem that how industrial production is evaluated and controlled based on sustainable development theory. Quality is one of the important indexes. Two mainstream theories guide us to realize the industrial sustainable development： mainly the circular economy and sustainable manufacturing are introduced. The basic characteristics of the sustainable manufacturing are introduced, and that quality management is important contents of sustainable development is indicated. Based on circular economy and sustainable manufacture theories, the drawbacks in the existing quality management models are analyzed. The requests that satisfy the big system ＂environment- society - economy＂ are summarized to build up a model. A Chinese traditional cultural principle is applied and the relevant contents are sublimated as the platform to set up the model. The new quality management concept models are put forward ＂T- D- R＂ three-dimensional structures and ＂ecological quality loop＂ model, from which the new quality concepts are formed The paper elaborates the contents and the process of setting up the models. The big quality problems of the system can be handled by the new quality concept and model that are validated in practice.

Water Status in Baghdad

Water is a strategically limited natural resource, and currently Iraq is in the grip of an extended drought period. It is needed to look for alternative water sources and work towards achieving high level of sustainability. Measurements for gray water samples were carried out including pH, EC （electrical conductivity）, TDS （total dissolved solids）, TS （total solids）, TSS （total suspended solids）, DO （dissolved oxygen）, BOD5 （biochemical oxygen demand）, COD （chemical oxygen demand）, alkalinity, chlorides （Cl）, calcium （Ca）, sodium （Na）, magnesium （Mg）, potassium （K）, lead （Pb）, TC （total coliforms）, TF （total fecal coliforms）, and nitrate （NO3）. The goals of this study are to estimate quantities of fresh water consumption and gray water generated in typical Baghdadian households, and to investigate gray water quality （physical, chemical and biological）. The major results can be summarized as follows： （1） The daily water consumption in Baghdad ranged from 75 Lpcd to 176 Lpcd with an average of 116 Lpcd; （2） the maximum daily consumption in Baghdad ranged from 124 Lpcd to 327 Lpcd with an average of 186 Lpcd; （3） the maximum hourly consumption in Baghdad ranged from 154 Lpcd to 900 Lpcd with an average of 308 Lpcd; （4） gray water generation in Baghdad ranged from 34 Lpcd to 139 Lpcd with an average of 68 Lpcd, and that gray water generated constituted 58% to 72% of total consumption.

Classification of Country Patterns in the World Based on Their Levels of Economy and Emission Process of Greenhouse Gases

According to the authoritative data involving social economic indicators and greenhouse gas （GHG） emission from the international universal database, the levels and processes of economic development and GHG emission in major economic groups, nations and regions of the world are simultaneously analyzed. Obtaining Gross Domestic Product （GDP） and emission per capita from various countries and regions in the past 40 years as the standard, countries and regions in the world are divided into six groups： countries with low emission per capita and low economic level （IA）, countries with low emission per capita and medium economic level （IIA）, countries with low emission per capita and high economic level （IIIA）, countries with high emission per capita and medium economic level （liB）, countries with high emission per capita and high economic level （IIIB）, countries with high emission per capita and low economic level （IB）. Countries belong to IB are quite rare in the study period, while the first five groups correspond to the poor regions, main developing countries, economically transitional countries with rapid economic development, rich islands and developed North America and Europe respectively. Data analysis shows that there is a close relationship between emission and economic development of different countries and regions. The composition relationship between economic development of different countries and regions is relatively stable over a long period of time. From 1970 to 2005, rising trends existed in the economic development of most countries and regions. However, the emission had a significant increase in a small part of countries and regions. In other words, for those with high emission, the emission level is always high. But for those with low GHG emission, the emission does not increase too much. The main processes of the change of countries pattern from IA to IIA and from II B to IIIB, occurring in the 1970s and from the late 1970s to the 1980s respectively. That result has .a significant enlightening effect in understanding the relationship between emission and eco- nomic development and its historical process of various countries and in choosing the position of our country in the future climate diplomatic negotiations.

Industrial Carbon Emissions Status and Analysis Based on Energy Consumption

With frequent disastrous weathers and increasingly prominent GHG effects in recent years, normal existence and development of mankind are facing unprecedented threats and challenges. GHG emissions mitigation for the global climate changes has been the focus of concern of the world. As the biggest developing country and the second largest country of carbon-emission, China attaches importance to the carbon emission reduction. The major GHG component is carbon dioxide and in China, the emis- sion of carbon dioxide is mainly from industrial production. In the paper, the status and trend of Coz emission from industrial departments, high-carbon emission and its specific industries are shown in statistics. Meanwhile, the policy environment, industrial organization structure and technology of carbon high emission are all discussed based on practical situations in these departments and industries. At the end, through the analysis of gray correlation, correlativity is explored for both fossil energy consumption and total carbon emission, and also for the production value and carbon emission of each industrial sector. Some policy proposals for the establishment of low-carbon industries and transition of economic development pattern are set forth.

Principles About Batho Pele Principles： South African Exploration and Analyses

This paper explores Batho Pele principles within the ambit of the South African legislative framework regularizing the public service. It informs that there are original principles apprising what is commonly referred to as Batho Pele principles. The original principles are principles about Batho Pele principles. Batho Pele principles are not Bantu principles due to the historical and derogatory orientation of the phrase ＂Bantu＂. They are people orientated principles. The analytical axis is premised on that Batho Pele principles are more about the people than about themselves. The people are not only first in relation with the principles but are the first to be first before the principles were documented. The principles are developed by the people in order to regularize the actions of the public functionaries. The Batho Pele principles and the original principles do not exist in isolation. They are deeply rooted in the societal value systems of the people that existed from one generation to the other to the subsequent, emphasizing the centrality of people in relation to principles. The people＇s centrality is accentuated with references to a reasonable number of specific people orientated instruments that have bearing in the global and international arena.

Discussion on the Construction of low-carbon electricity technology innovation system

With the issue of climate change increasingly restricting the sustainable development of society, people must realize that we must control atmospheric concentrations of greenhouse gases at a certain level. However, the traditional model of economic development will lead to human demand for energy continuing to grow, followed by a growth in emissions of carbon dioxide. Obviously we must ensure that there is rapid economic development, but also to protect the human living environment, which is a very sharp contradiction. A good solution to this conflict is to take a new model of development --- a low-carbon economy. The so-called low-carbon economy refers to the reduction of greenhouse gas emissions, the application of new technologies, new materials and new practices, etc., through improvements, optimization or innovative production and business activities, to achieve the maximum degree of reduction of greenhouse gas emissions, and the formation of a new economic development model, the goal is to mitigate climate change and promote sustainable human development. On how to develop a low-carbon economy, domestic and foreign scholars have been studied from many angles, one of which is a consensus to reduce greenhouse gas emissions through the development and use of low-carbon technologies.

Carbon budget proposal： a framework for an equitable and sustainable international climate regime

A worldwide consensus on reducing greenhouse gas emissions has been reached at the technical and political level. However, as the issue involves economic costs and developmental interests, the international institutional framework for addressing global greenhouse gas emissions has consistently failed to balance the demands of equity and sustainability. But the sustainability of carbon budget proposal is undoubtedly achievable if the total global carbon budget （the total amount of carbon permitted by climate security） is made an absolute constraint. If an initial allocation is made among all members of the global village on a per capita basis, a limited total budget could not only meet basic needs but also ensure equity. Taking into account historical emission levels and future needs, we should implement carbon budget transfer payments and devise a corresponding financial mechanism to ensure efficient allocation. Unlike the phase-by-phase progress and provisional goals of the Kyoto Protocol, the carbon budget proposal presented here is a comprehensive and holistic package. Due to the politicization of the climate change question, however, many technical issues can only be worked out through international political and diplomatic negotiations.

Potentials of GHG reductions from wastewater treatment for the CDM

The study aims to evaluate the potential of GHG （greenhouse gas） reductions by installing an anaerobic digester in a wastewater treatment facility in Southeast Asia. Then the break-even point of additional investment to reduce GHG is obtained by exchanging carbon price as emissions credits. In the project scenario, the wastewater treatment system has the digester, where methane （biogas） is produced and recovered. Compared with the baseline scenario, the biogas has calorific value to produce heat and electricity, and can substitute fossil fuels for power generation. The objective of the study is to define the relationship between CERs （certified emission reductions） and investment costs, and the beak-even point, finding out the dominant pa- rameters in the system. Financial parameters such as capital costs and operating costs are considered to evaluate the investmerit costs. The result shows that the methane recovery reduces 54% of GHG emissions. Although the substitution of the biogas for the fossil fuels reduces only 6% of the GHG emissions, the electricity output can satisfy the electricity consumption. The results also show that the maximum CER credit is 73000 t-COEe/a, and the GHG reduction cost is 14 USD/t-CO2e.
