Strength Analysis for the Adhesive Layer on the Basis of Intensity of Singular Stress

In this paper the strength of adhesive joint under tension and bending is discussed on the basis of intensity of singular stress by the application of FEM. A useful method is presented with focusing on the stress at the edge of interface between the adhesive and adherent obtained by FEM. After analyzing the adhesive joint strength with all material combinations, it is found that to improve the interface strength, thin adhesive layers are desirable because the intensity of singular stress decreases with decreasing of the thickness.11th International Conference on the mechanical behavior of Materials (ICM11), 5-9 June 2011, Como, Ital

Development of 3D Bit-Map-Based CAD and Its Application to Hydraulic Pump Model Fabrication

A novel 3D bit-map-based CAD has been developed. This program, named CellCAD, relies on techniques which provides easy manipulation of huge sized 3D bit-map, poly-triangle and 2D bit-map data. It can be attached to various kinds of additional plug-in processors to extend its functions and to customize it highly for broad applications. CellCAD can be applied in fields using computed tomography digitizers and/or layering fabricators. The authors applied CellCAD to hydraulic pump model fabrication. This paper reports the basic design concept and implementation techniques of CellCAD from the viewpoint of design engineering, and also introduces the methods and results of an actual CellCAD application.Mechanical Engineerin

Behaviour-Based Husbandry-A Holistic Approach to the Management of Abnormal Repetitive Behaviors

The field of zoo animal welfare science has developed significantly over recent years. However despite this progress in terms of scientific research, globally, zoo animals still face many welfare challenges. Recently, animal welfare frameworks such as the five domains or five needs have been developed and suggested to improve the welfare of zoo animals, but without practical guidance, such tools may remain abstract from the daily experience of zoo animals. Similarly specific practical strategies such as those for enrichment development exist, but their lack of holistic integration with other aspects of animal husbandry and behavioral medicine means that overall, good zoo animal welfare may still be lacking. This paper outlines some of the barriers to implementing improved zoo animal welfare in practice, and proposes a new strategy for the development of behavioral husbandry routines focused on the management and mitigation of abnormal repetitive behaviors. Focusing on enhancing zoo animal welfare by integrating aspects of ecology, ethology and clinical animal behavior into a practical and comprehensive approach to behavior-based husbandry

Lateral Lumbar Interbody Fusion with Percutaneous Pedicle Screw in Combination with Microendoscopic Laminectomy in the Lateral Position for Lumbar Canal Stenosis

A minimally invasive surgical (MIS) procedure is an ideal surgical procedure. Many MIS techniques have been reported in spinal surgery. In clinical practice, we often encounter two-level canal stenosis cases, in which one level shows instability and the other does not. In such a case, fusion surgery for one level and decompression surgery for the other level is ideal. LLIF/OLIF approached from the lateral side has been reported effective. MIS decompression techniques in the lateral decubitus position have never been reported. We devised a surgical method that can accomplish both fixation and decompression in a consistent lateral decubitus position

PLAG1 enhances the stemness profiles of acinar cells in normal human salivary glands in a cell type-specific manner

Objectives: Details of the histogenesis of salivary gland tumors are largely unknown. The oncogenic role of PLAG1 in the salivary gland has been demonstrated in vivo. Herein, we demonstrate the roles of PLAG1 in the acinar and ductal cells of normal human salivary glands in an attempt to clarify the early events that occur during the histogenesis of salivary gland tumors. Methods: Normal salivary gland cells with acinar- (NS-SV-AC) and ductal- (NS-SV-DC) phenotypes were transfected with PLAG1 plasmid DNA. Subsequently, the PLAG1 overexpressed and mock cells were examined by cell proliferation, transwell migration, and salisphere formation assays. The expression levels of salivary and pluripotent stem cell markers and differentiation markers were evaluated by quantitative real-time polymerase chain reaction and immunofluorescence. Alterations in transcriptional expressions were investigated via cap analysis of gene expression with gene-enrichment and functional annotation analysis. Results: PLAG1 promoted cell proliferation and transwell migration in the acinar and ductal cells, and markedly enhanced the stemness profiles and luminal cell-like profiles in acinar cells; the stemness profiles were partially increased in the ductal cells. Conclusion: PLAG1 enhanced the stemness profiles in the acinar cells of normal human salivary glands in a cell type-specific manner. Thus, it may be involved in salivary gland tumorigenesis by increasing the stemness character of the normal salivary gland cells

サキシマフヨウの花の形質と変異，特にフヨウとの比較において

Floral characters and their variations of Hibiscus makinoi Jotani et H. Ohba were examined in comparison with H. mutabilis L. Hibiscus makinoi, distributed from the Ryukyu Islands to western Kyushu of Japan, has been confused with H . mutabilis which is widely cultivated and sometimes escaped in western Japan. Eight flo-ral characters ; petal length, petal width, style length, anther-anther distance, anther-stigma distance, number of anthers, number of episepals, episepal width, and potential number of seeds per fruit and dry seed weight were measured for 10 individuals of H . makinoi and for 7 individuals of H . mutabilis, respectively. The petal length and width, style length, anther-anther distance, anther-stigma distance, and number of stamens of H . makinoi were signficantly smaller, and the episepal width was wider than those of H . mutabilis. Floral vari-ations in color and form of H . makinoi might be due to its ruderal habitat and for pollinators
