Object-oriented construction of a multigrid electronic-structure code with Fortran 90

We describe the object-oriented implementation of a higher-order finite-difference density-functional code in Fortran 90. Object-oriented models of grid and related objects are constructed and employed for the implementation of an efficient one-way multigrid method we have recently proposed for the density-functional electronic-structure calculations. Detailed analysis of performance and strategy of the one-way multigrid scheme will be presented.Comment: 24 pages, 6 figures, to appear in Comput. Phys. Com

Resistant Starch from Exotic Fruit and Its Functional Properties: A Review of Recent Research

Resistant starch is a functional food ingredient that can resist enzymatic digestion in the small intestine and fermentation in large intestine. Resistant starch has many benefits to human health by promoting a balanced blood sugar and beneficial gut bacteria. This review highlighted the sources of different exotic fruit starch, such as banana, jackfruit, cempedak, durian, and breadfruit. The functional properties of these exotic fruit resistant starches were covered in this review. The effect of resistant starch on glycaemic index of food was revealed. This review also discussed on the applications of resistant starch in the production of food products and their effects on food quality. The provided information through the overall review could especially benefit the food industry in producing functional food products with great consumer acceptability

A Suspended Nanogap Formed by Field-Induced Atomically Sharp Tips

A sub-nanometer scale suspended gap (nanogap) defined by electric field-induced atomically sharp metallic tips is presented. A strong local electric field (\u3e109 V=m) across micro/nanomachined tips facing each other causes the metal ion migration in the form of dendrite-like growth at the cathode. The nanogap is fully isolated from the substrate eliminating growth mechanisms that involve substrate interactions. The proposed mechanism of ion transportation is verified using real-time imaging of the metal ion transportation using an in situ biasing in transmission electron microscope (TEM). The configuration of the micro/nanomachined suspended tips allows nanostructure growth of a wide variety of materials including metals, metal-oxides, and polymers.

THE KINEMATIC ANALYSIS OF 500M SPRINT START IN 2005 WORLD SHORT TRACK SPEED SKATING CHAMPIONSHIP

A field study was performed attempting a kinematic estimation for six female foreign skaters, who participated in the 500m female final round competition. The three dimensional motion analysis with DLT method was executed using four video cameras for analyzing the actual competition situation. The following conclusions are drawn; the elapsed time by phase in start motion of the foreign skaters appeared shorter than those of Korean skaters, so the start training of Korean skaters should be strengthened. Also the displacement of COG in the foreign skaters appeared shorter than those of Korean skaters. The velocity of COG and maximum velocity of skate blade of foreign skaters are faster than those of Korean skaters. And the foreign skaters showed the superior early velocity change

An Empirical Study on the Importance of Psychological Contract Commitment in Information Systems Outsourcing

In IS outsourcing relationship literature, research has focused on detailed legal contracts and partnerships. We investigate the role of psychological contracts between client and vendor in the IS outsourcing context. The aim of this paper is to put the concept “psychological contract commitment” (PCC) under the spotlight, finding out its mediating effects between legal contracts/partnerships and IS outsourcing success. By analyzing 50 matched survey responses gathered from project managers, vendor firms, and end-users, we found that psychological contract commitment has both direct and mediating effects on outsourcing success. Along the same lines, the key findings suggest that psychological contract commitment explains why legal contracts and partnerships are still crucial to IS outsourcing success

Characterization Of Banana (Musa Acuminata × Balbisiana Cv. Awak) Pseudo-Stem Flour And Its Potential In The Development Of Novel Fibre-Rich Bread

The physico-chemical and functional properties of banana pseudo-stem flour (BPF) was compared with the commercial wheat flour (CWF). Unbleached and bleached cellulose were prepared from BPF. Various flour blends were formulated; CWF (FCWF), FCWF was substituted with 10% BPF (F10BPF) and F10BPF with added 0.8% w/ w (flour weight basis) xanthan gum (XG) or sodium carboxymethyl cellulose (Na CMC) (F10BPFXG or F10BPFCMC, respectively). The formulated flour blends were subjected to the mixing, pasting, and thermal profiles analyses. Novel composite breads by partially substituting BPF for control CWF bread (BCtr) at 10% level (B10BPF) and B10BPF added with 0.8% w/ w of XG or Na CMC (B10BPFXG or B10BPFCMC, respectively) were prepared and evaluated for the physico-chemical, nutritional and sensory. The proximate contents (fat, ash, crude fibre and carbohydrate), macro and micro elements, total dietary fibre (TDF), insoluble dietary fibre (IDF), soluble dietary fibre (SDF), total sugars, pentosans, total phenolics, antioxidants activity, pH, ⁰Brix, titratable acidity, water and oil holding capacities were significantly (p< 0.05) higher in BPF than in CWF. BPF had low bulk density, water activity (aw) and lightness value. Low yield and high crystallinity were obtained from bleached cellulose as confirmed by the fourier transform infrared spectroscopy and x-ray diffraction results. All composite flour blends showed significantly (p< 0.05) high water absorption and mixing tolerance index with decreased in gelatinization enthalpy change (ΔHg), breakdown, final viscosity and setback values

Investigation of the SH3BP2 Gene Mutation in Cherubism

Cherubism is a rare developmental lesion of the jaw that is generally inherited as an autosomal dominant trait. Recent studies have revealed point mutations in the SH3BP2 gene in cherubism patients. In this study, we examined a 6-year-old Korean boy and his family. We found a Pro418Arg mutation in the SH3BP2 gene of the patient and his mother. A father and his 30-month-old younger brother had no mutations. Immunohistochemically, the multinucleated giant cells proved positive for CD68 and tartrate-resistant acid phosphatase (TRAP). Numerous spindle-shaped stromal cells expressed a ligand for receptor activator of nuclear factor kB (RANKL), but not in multinucleated giant cells. These results provide evidence that RANKL plays a critical role in the differentiation of osteoclast precursor cells to multinucleated giant cells in cherubism. Additionally, genetic analysis may be a useful method for differentiation of cherubism.</p
