CARBON CAPTURE AND STORAGE(CCS) RESEARCH COLLABORATION TRENDS USING NETWORK ANALYSIS OF SCI PAPERS

Climate change has become one of the most important global agenda, and nations worldwide are taking actions to resolve the issue and contribute to the new climate change regime. In the case of South Korea, the new goal of reducing greenhouse gas emission to 37% below BAU(Business-As- Usual) was set. As a means to achieve this goal, the Korean government is actively investing in highly effective greenhouse reduction technologies such as solar cell, fuel cell, bioenergy, secondary battery, power IT, and CCS(Carbon Capture and Storage). This paper investigates the overall trend of CCS research by examining international CCS research collaboration characteristics through network analysis of SCI papers; collaboration network of Korea is analyzed in further detail. Such analysis helps understand the status of international research in the field of CCS, especially that of Korea

IMECE2005-80702 THE MESOSCOPIC SIMULATION ON THE STRUCTUES OF THE SURFACTANT SOLUTION USING DISSIPATIVE PARTICLE DYNAMICS

ABSTRACT With a simple model of surfactant which consists of hydrophilic head group and hydrophobic tail groups connected by harmonic springs, structural change of the association structures of surfactant in an aqueous solution was studied using the dissipative particle dynamics (DPD) simulation. The effect of the hydrophilic interaction between the head and water molecules and the hydrophobic interaction between the tail and water molecules and the head and tail on the structural change of the association structures was studied. Simulations show that proper value of these interaction parameters could yield desirable change of the association structure depending on the concentration of the surfactant. For example, a hexagonal structure appears when the volume fraction of surfactant of SDS (sodium dodecyl sulfate) becomes 25 % in aqueous solution, which is in good agreement with observation

Integration between WSNs and Internet based on Address Internetworking for Web Services

There has been an increasing interest in wireless sensor networks as a new technology to realize ubiquitous computing, and demands for internetworking technology between the wireless sensor networks and the Internet which is based on IP address. For this purpose, this paper proposes and implements the internetworking scheme which assigns IP addresses to the sensor nodes and internetworks based on the gateway-based integration for internetworking between the wireless sensor networks and the Internet. That is, the proposed scheme makes the access to the wireless sensor networks be serviced as like the Web service with internetworking Internet IP address and ZigBee address which is allocated to the sensor node in wireless sensor networks. For validating the proposed scheme, we made experiments using Berkeley TinyOS, Mica Motes, dual protocol stack based on ZigBee and IP, and showed the service result using browser (IE) and IPv6 address based on DNS

Solitary Fibrous Tumor of the Pancreas: Imaging Findings

We report here a case of a pathologically proven solitary fibrous tumor of the pancreas. A 54-year-old man was referred to our hospital for further evaluation of a pancreatic mass that was found incidentally. CT, MR imaging, and endoscopic ultrasonography showed a well-defined, enhancing mass with cystic portions of the pancreas body. MR cholangiopancreatography showed no pancreatic duct dilatation. A solitary fibrous tumor of the pancreas is a very rare lesion

Long term assessment of root coverage stability using connective tissue graft with or without an epithelial collar for gingival recession treatment. A 12-year follow-up from a randomized clinical trial

AimTo evaluate the long term root coverage outcomes of coronally advanced flap plus a connective tissue graft with (CAF + CTG) or without an epithelial collar (CAF + ECTG), and evaluate the adjacent treated sites included in the flap.MethodsSeventeen of the original 20 subjects included in the randomized clinical trial were available at 12 years (43 sites). Mean root coverage (mRC), keratinized tissue width (KTW), gingival thickness (GT) on the grafted and adjacent sites were evaluated and compared with baseline and 6 months.ResultThere was a reduction in the mRC at all sites: 16.52% in the CAF + CTG (p > .05), 19.42% in the CAF + ECTG (p  .05). Keratinized tissue width at baseline and at 6 months was found to be predictors for the stability of the gingival margin in the long term.ConclusionsCAF + CTG and CAF + ECTG were found equally efficacious in maintaining the levels of the gingival margin with a small amount of relapse over the period of 12 years while CAF-alone sites showed a greater gingival recession (GR) reoccurrence.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151994/1/jcpe13187_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151994/2/jcpe13187.pd

Generation of high concentration nanobubbles based on friction tubes

Nanobubble-related technologies have been confirmed to be useful in various fields such as climate change and the environment as well as water-based industries such as water purification, crops, horticulture, medical care, bio, and sterilization. However, a method of mass production in real time enough to apply nano-bubbles to the industry has not yet been developed. We explored the mechanism of nano-bubble water generation by friction between water and walls and developed a tube device applying the shape of the flow path to maximize the friction in the fluid passing through the flow path. It also describes the case of real-time and low-power mass production of nanobubbles and its technical utility. We found that the friction of nanotubes alone can easily and quickly improve the production of nanobubbles with small particle size in real time; by increasing the shearing pressure while increasing the effective friction constant value, the particle size of nanobubbles can be smaller while increasing the particle concentration.Comment: 24 pages, 24 figures, 6 table
