Micro bubble formation and bubble dissolution in domestic wet central heating systems
Fsadni Andrew M.,Ge Yunting
EPJ Web of Conferences , 2012, DOI: 10.1051/epjconf/20122501016
Abstract: 16 % of the carbon dioxide emissions in the UK are known to originate from wet domestic central heating systems. Contemporary systems make use of very efficient boilers known as condensing boilers that could result in efficiencies in the 90-100% range. However, research and development into the phenomenon of micro bubbles in such systems has been practically non-existent. In fact, such systems normally incorporate a passive deaerator that is installed as a ‘default’ feature with no real knowledge as to the micro bubble characteristics and their effect on such systems. High saturation ratios are known to occur due to the widespread use of untreated tap water in such systems and due to the inevitable leakage of air into the closed loop circulation system during the daily thermal cycling. The high temperatures at the boiler wall result in super saturation conditions which consequently lead to micro bubble nucleation and detachment, leading to bubbly two phase flow. Experiments have been done on a test rig incorporating a typical 19 kW domestic gas fired boiler to determine the expected saturation ratios and bubble production and dissolution rates in such systems.
Reproductive Biology of Ficus beipeiensis  [PDF]

American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.618286
Abstract: This paper uses morphological, anatomical and ecological methods to study the morphological characteristics and propagation mechanism of Ficus beipeiensis S.S Chang which is endemic to China, providing a scientific basis for the rare population of wild plants and repopulation. The following results were obtained. First, F. beipeiensis with pollinating fig wasps was highly adapted in morphological structure and behavior. Second, a monoclinous flower period existed during the developmental phase of male flowers. F. beipeiensis had one to four stamens and one pistil. The pistil in the stigma of syconium flowers was similar to that of gall flowers, but no pollinating fig wasps that laid eggs in the ovary were found. Third, wild individual specimens were found to be rare. The investigation found only one male and four female individuals among them. However, only two female plants can bear fruits. The remaining 9 female plants were cultivated, among which only four grew syconia. No fruit, seed germination, and seeding were found under natural conditions. Several possible reasons for the growth of rare wild plants can be found as following: 1) An imbalance between male and female plants reduces breeding efficiency; 2) Ceratosolen sp. is a species-specific pollinator of F. beipeiensis, so the gall rate is lower; 3) The high mortality of Ceratosolen sp. results in low pollination rate; 4) The seed rate [25.64% ± 54.13% (N = 50)] is lower, ranging from 2% to 70%; 5) Seed germination is difficult under natural conditions.

Correlation among SDS Sedimentation Value, Swelling Index of Glutenin and Solvent Retention Capacity of Spring Wheat

Notulae Scientia Biologicae , 2012,
Abstract: The determination of flour end-use quality of progenies is a routine process in high-quality wheat breeding program. Traditional determination involves larger amount of flour and specific instruments, meanwhile, is expensive and time-consuming. A rapid and accurate method which could predict the quality of early generation wheat lines is in high demand in the wheat breeding program. Clarifying the relationships among different prediction indexes is the prerequisite for devising a new prediction method screening the high-quality progenies. This study aimed to clarify the correlations between SDS sedimentation value, SIG and SRCs for both wholemeal flour and flour, as well as to study which parameter could be applied to predict the flour quality of spring wheat rapidly and conveniently. The result of the study showed that WSRC correlated significantly with all the parameters determined, the four different SRCs varied significantly between hard wheat and soft wheat, while SDS sedimentation value and SIG showed no significant difference between hard wheat and soft wheat. SRC test may provide a convenient method for predicting the quality of early generation wheat lines in wheat breeding.
Existence and Nonexistence of Global Solutions of a Fully Nonlinear Parabolic Equation  [PDF]
Zhihao Ge
Advances in Pure Mathematics (APM) , 2013, DOI: 10.4236/apm.2013.31004
Abstract: In the paper, we study the global existence of weak solution of the fully nonlinear parabolic problem (1.1)-(1.3) with nonlinear boundary conditions for the situation without strong absorption terms. Also, we consider the blow up of global solution of the problem (1.1)-(1.3) by using the convexity method.
Research on Serving the Development of Regional Economy Innovation by Intellectual Properties in Universities  [PDF]
Ge Li
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.23005
Abstract:

At present, a sound intellectual property management and service system have not been established yet in Chinese colleges and universities. Meanwhile, the lost of existing intellectual property in universities due to small amount, low conversion rate, low technology content and weak brand awareness, hinders the positive effect of intellectual property and affects its transformation and application in China. This article introduces the current problems with intellectual property in universities and gives some countermeasures to promote the use of intellectual property in universities for a better regional economic service.

The Property of a Special Type of Exponential Spline Function  [PDF]
Ge Yang
Advances in Pure Mathematics (APM) , 2015, DOI: 10.4236/apm.2015.513074
Abstract: Approximation theory experienced a long term history. Since 50’ last century, the rise of spline function as well as the advance of calculation promotes the growth of classical approximation theory and makes them develop a profound theory in maths, and application values have shown among the field of scientific calculation and engineering technology and etc. At present, the study of spline function had made a great progress and had a lot of fruits, as for that, the reader could look up the book [1] or [2]. Nevertheless, the research staff pays less attention to exponential spline function, since polynomial spline function is a special case of that, so it is much essential and meaningful for one to explore the nature of exponential spline function.

Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.63065
Abstract: Central economical zone is an important part of China’s regional economy. As a new growth pole, it will have a programmatic guidance to the reconstruction of the regional economy territory. Its development will have a significant positive impact on our country. To grasp opportunities and develop, we must start from the reality of the province and develop e-commerce, making it become the new economic growth point. This article utilizes the SWOT analysis and combines internal and external environment of electronic commerce, pointing out opportunities and threats that Henan face when developing electronic commerce.

Modern Economy (ME) , 2016, DOI: 10.4236/me.2016.76077
Abstract: As a technical and commercial revolution, e-commerce has an impact on the development of social economy more and more profoundly, and changes men’s business model and lifestyle fundamentally. Shortages of talents on e-commerce have become a “bottleneck” restricting China’s e-commerce development. However, undergraduate teachings in e-commerce have some shortcomings. Out of line with social demands, trainings for talents are of low quality. Therefore, reflecting problems of current undergraduate teachings in e-commerce, thus to explore solutions to these problem is undoubtedly of great theoretical and practical significance.
