Effects of laser wavelength and density scalelength on absorption of ultrashort intense lasers on solid-density targets

Hot electron temperatures and electron energy spectra in the course of interaction between intense laser pulse and overdense plasmas are reexamined from a viewpoint of the difference in laser wavelength. The hot electron temperature measured by a particle-in-cell simulation is scaled by $I$ rather than $I \lambda^2$ at the interaction with overdense plasmas with fixed ions, where $I$ and $\lambda$ are the laser intensity and wavelength, respectively.Comment: 12th International Congress on Plasma Physics, 25-29 October 2004, Nice (France

Effect of Calcium Silicate Application on the Alleviation of Metal Toxicity in Lowland Rice and Wheat Plants

土壌中に過剰に存在するアルミニウム,マンガン,ニッケル,銅およびカドミウムが水稲および小麦の生育におよぼす障害について培地に添加した可溶性ケイ酸の吸収が金属過剰害を軽減するか否かについて検討し,つぎのような知見が得られた. 1)水稲のニッケル過剰害軽減にケイ酸の効果が認められた. 2)ケイ酸は水稲の茎葉から穂へのマンガンの移行を抑制した. 3)水稲のアルミニウム過剰呼吸によって,茎葉中のケイ酸および鉄含有率を著しく増加させた. 4)小麦のアルミニウム過剰害に対しケイ酸は地上部のアルミニウム含有率を減少させ収量を増加させた

Influence of nut shell powder content on the tribological properties of recycled polyolefin composites

The purpose of this study is to investigate the influence of nut shell powder (NSP) content on the tribological properties of recycled polyolefin (R-PO) composites. NSP was previously grinded the dried nut shell by crusher machine cryogenically in liquid nitrogen. NSP/R-PO composites with NSP content of 5, 10 and 20 vol.% were prepared in this study. These composites were extruded by a twin screw extruder and injection-molded. Their tribological properties were measured by a reciprocating type sliding wear tester at constant normal load and sliding speed under dry condition. It was found that NSP is effective for reducing the wear resistance of R-PO, and the influence of NSP content on the tribological properties of NSP/R-PO composites does not remarkably appear, but they are improved with the addition of low content such as 5 vol.%. This may be attributed to the change of wear mechanism according to the filling of NSP. © 2016 Author(s).MEXT, Ministry of Education, Culture, Sports, Science, and Technolog

Localized Immunoglobulin Light-Chain Amyloidosis of the Ulnar Nerve

Amyloidosis is a disorder caused by extracellular tissue deposition of insoluble fibrils. Amyloidosis can be divided into systemic or localized disease. Primary systemic amyloidosis is a multisystem disease caused by the deposition of amyloid in various tissues. Localized amyloidosis has different characteristics than those of systemic amyloidosis. In this paper, we present the case of a middle-aged woman who presented with worsening ulnar nerve palsy. Electrophysiological examination and MRI indicated a tumor surrounding the ulnar nerve in the forearm. However, the operative findings revealed that ulnar nerve fascicles were replaced with a yellow tissue, which was diagnosed as amyloid light-chain λ amyloidosis, based on histopathological examination. Systemic amyloidosis was ruled out after the screening examinations. This paper is the first report of the ulnar nerve as the sole site of localized immunoglobulin light-chain amyloidosis manifestation
