Electron microscopy was used to measure microvillous surface area in seven small intestinal biopsies showing secondary disaccharidase deficiency and in five biopsies having normal disaccharidase levels. There were significant reductions in microvillous surface area in the enzyme deficient group, although the microvilli were not severely damaged. Histological abnormality was not always present w...

In this paper, we propose a Kohonen feature map associative memory with area representation for sequential patterns. This model is based on the Kohonen feature map associative memory with area representation and the Kohonen feature map associative memory for temporal sequences. The proposed model can learn sequential patterns successively, and has robustness for damaged neurons. We carried out ...

the influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. the incorporation of nanoclay into epoxy enhances the impact resistance of the composites. the impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...

The magnitude-9.0 Great East Japan Earthquake, which struck at 14:46 JST on March 11, 2011, was the largest ever recorded in Japan. Strong quakes were felt not only in Tohoku, the closest region to the epicenter, but also nationwide from Hokkaido to Kyushu. This exceptional event was followed by huge tsunami waves that severely damaged the Fukushima Daiichi nuclear power plant, which consequent...

Earthquakes leave in their wake permanently deformed ground. These deformations take on extremely complex surfaces and shapes. A new technology, 3-D laser-scanning Light Detection And Ranging (LIDAR), allows for the rapid and remote sensing of damaged terrain to construct ultra-high resolution 3-D models of the ground. Scanning LIDAR targets the damaged area with sequenced LASER pulses that, in...

Antioxidant effects of Chitosan nano-green tea on hepatic fibrosis was studies ultrastrucutrally with detailed quantification comparing the percentage differences between the damaged done by CCl4 and ethanol effects and the rehabilitation by the use of Chitosan nano-green tea’s antioxidant effect. Especially in demolishing the damaging effects of CCl4 and ethanol on both the cell cytoplasm and ...

Abstract: The timely detection of gold foil damage in gold-overlaid stone carvings and the associated maintenance of these relics pose several challenges to both the research and heritage protection communities internationally. This paper presents a new method for detecting gold foil damage by making use of multi-temporal 3D LiDAR point clouds. By analyzing the errors involved in the detection ...

Although secondary delayed neuronal death has been considered as a therapeutic target to minimize brain damage induced by several injuries, delayed neuronal death does not occur always. In this study, we investigated possible mechanisms that prevent delayed neuronal death in the ATP-injected substantia nigra (SN) and cortex, where delayed neuronal death does not occur. In both the SN and cortex...

The northeastern region of Bangladesh often experiences flash flooding during the pre-harvesting period of the boro rice crop, which is the major cereal crop in the country. In this study, our objective was to delineate the impact of the 2017 flash flood (that initiated on 27 March 2017) on boro rice using multi-temporal Landsat-8 OLI and MODIS data. Initially, we opted to use Landsat-8 OLI dat...
