Formulating for Innovative Self-Compacting Concrete with Low Energy Super-Sulfated Cement Used for Sustainability Development  [PDF]
Hoang-Anh Nguyen, Ta-Peng Chang, Jeng-Ywan Shih, Chun-Tao Chen
Journal of Materials Science and Chemical Engineering (MSCE) , 2016, DOI: 10.4236/msce.2016.47004
Abstract:

This study proposed a new way to formulate a low energy super-sulfated cement (SSC) which can be used to produce self-compacting concrete (SCC) with high compressive strength and durability in terms of chloride penetration resistance. This innovative SSC, different from the traditional SSC, was purely produced with a ternary mixture of three industrial by-products of ground granulated blast furnace slag, low calcium Class F fly ash and circulating fluidized bed combustion (CFBC) fly ash and was denoted as SFC-SSC (super-sulfated cement made by mixture of slag, Class F fly ash and CFBC fly ash). Experimental results showed that the combination of a fixed amount of 15 wt.% of CFBC fly ash with various ratios of Class F fly ash to slag could be used to produce the hardened SCCs with high 28-day compressive strengths (41.8 - 65.6 MPa). Addition of Class F fly ash led to the resulting SCCs with lowered price and preferable engineering properties, and thus it was considered as state-of-the-art method to drive such type of concrete towards sustainable construction materials.

Evaluations and Selections for High Isoflavone Black Soybean Mutants Induced by NaN3 Treatment  [PDF]
Toong Long Jeng, Yi Ju Shih, Min Tze Wu, Chiang Sheng Wang, Jih Min Sung
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.48A004
Abstract:

Sodium azide (NaN3) (2 mM) was used to induce mutation in black soybean variety CRWD for improvement of isoflavone content. The individual selections were made in M6, M7 and M8 generations, respectively. Both high levels of isoflavones and medium seed size traits were used as selection criteria. Across three growth seasons, the selected five NaN3-induced mutants accumulated more total isoflavones (average increases of 5% to 25%) than their wild type variety CRWD. Four mutants yielded more (average increases of 17% to 25%) than CRWD. Both mutants SA-M-03 (yellow cotyledon) and SA-M-05 (green cotyledon) are rich in isoflavones and may be useful in food and other applications.

Discovery of the female of Pyrocoelia prolongata in Taiwan (Coleoptera, Lampyridae)
Ming-Luen Jeng,Michael Engel,Ping-Shih Yang
ZooKeys , 2011, DOI: 10.3897/zookeys.116.1412
Abstract: The female of Pyrocoelia prolongata Jeng & Lai, a diurnal lampyrid species from Taiwan, is described for the first time. A single individual was found in a small, shady, dry streambed at the edge of a mixed forest at 2700 m elevation. The individual glowed in darkness and would move its abdomen up and down when disturbed and as a deterring behavior. A key to the females of the species of Pyrocoelia Gorham in Taiwan is provided. The morphology of photogenic organs of females and the function of bioluminescence of day-active species of Pyrocoelia are discussed.
Laparoscopic resection of gastric gastrointestinal stromal tumors presenting as left adrenal tumors
Shiu-Dong Chung,Jeff Shih-chieh Chueh,Hong-Jeng Yu
World Journal of Gastroenterology , 2012, DOI: 10.3748/wjg.v18.i1.96
Abstract: Gastrointestinal stromal tumors (GISTs) are rare gastrointestinal malignancies. They are rarely seen near the urinary tract. In a literature review, only one case of GIST presenting as a left adrenal tumor was reported. We report two documented cases of gastric GISTs mimicking left adrenal tumors which were successfully treated with pure laparoscopic adrenalectomy and wedge resection of the stomach by excising the tumor from the stomach with serial firing of endoscopic gastrointestinal staplers. The surgical margins were clear, and the patients recovered smoothly. No adjuvant therapy with imatinib was prescribed. During the surveillance for 9 mo and 44 mo respectively, no tumor recurrence and metastasis were documented. Laparoscopic tumor excision, when adhering to the principles of surgical oncology, seems feasible and the prognosis is favorable for such tumors.
Coincidence and fixed point theorems for functions in S-KKM class on generalized convex spaces

Abstract: We establish a coincidence theorem in S-KKM class by means of the basic defining property for multifunctions in S-KKM. Based on this coincidence theorem, we deduce some useful corollaries and investigate the fixed point problem on uniform spaces.

Idiopathic Spinal Epidural Lipomatosis – Two Cases Report and Review of Literature
Jun-Yeen Chan,Chih-Ju Chang,Chin-Ming Jeng,Shih-Hung Huang
Chang Gung Medical Journal , 2009,
Abstract: Spinal epidural lipomatosis (SEL), an abnormal localized or tumor-like accumulation offat in the epidural space, is an infrequent complication of chronic steroid usage and anuncommon cause of spinal cord compression. During the period of 1990 to 2006, we havetwo cases of medically heath SEL patients without history of steroid administration. Theirinitial clinical manifestations were low back pain, progressive lower extremities weakness,numbness, followed by rapid deterioration of neurogenic intermittent claudication. Theywere misdiagnosed and treated as degenerative spinal disease for a long time. Due to prominentneurological deficit, lumbar magnetic resonance image (MRI) was obtained andshowed SEL. These 2 patients all underwent laminectomy and removal of epidural fat. Postoperatively,they both showed improvement. We reviewed the literature and discussed thecurrent concept in the management of SEL.
Partially incoherent optical vortices in self-focusing nonlinear media
Chien-Chung Jeng,Ming-Feng Shih,Kristian Motzek,Yuri Kivshar
Physics , 2003, DOI: 10.1103/PhysRevLett.92.043904
Abstract: We observe stable propagation of spatially localized single- and double-charge optical vortices in a self-focusing nonlinear medium. The vortices are created by self-trapping of partially incoherent light carrying a phase dislocation, and they are stabilized when the spatial incoherence of light exceeds a certain threshold. We confirm the vortex stabilization effect by numerical simulations and also show that the similar mechanism of stabilization applies to higher-order vortices.
MATEX: A Distributed Framework for Transient Simulation of Power Distribution Networks
Hao Zhuang,Shih-Hung Weng,Jeng-Hau Lin,Chung-Kuan Cheng
Computer Science , 2015,
Abstract: We proposed MATEX, a distributed framework for transient simulation of power distribution networks (PDNs). MATEX utilizes matrix exponential kernel with Krylov subspace approximations to solve differential equations of linear circuit. First, the whole simulation task is divided into subtasks based on decompositions of current sources, in order to reduce the computational overheads. Then these subtasks are distributed to different computing nodes and processed in parallel. Within each node, after the matrix factorization at the beginning of simulation, the adaptive time stepping solver is performed without extra matrix re-factorizations. MATEX overcomes the stiff-ness hinder of previous matrix exponential-based circuit simulator by rational Krylov subspace method, which leads to larger step sizes with smaller dimensions of Krylov subspace bases and highly accelerates the whole computation. MATEX outperforms both traditional fixed and adaptive time stepping methods, e.g., achieving around 13X over the trapezoidal framework with fixed time step for the IBM power grid benchmarks.
