The viscous and the external forces effect on thermal DNA denaturation of Peyrard-Bishop model are investigated. The calculation of the partition function to determine the stretching of hydrogen bonds has been performed by path integral Monte-Carlo. The result shows that the interaction between the viscous potential a…
In this study, the effect of water-soluble components on the thermal fluidity of steam-treated bamboo powder was investigated. Bamboo powders were steam-treated at 180 or 200 °C for various steam treatment times. The bamboo powders were then treated with hot water to extract the water-soluble components. The flow rate…
An LSI for the Massive Parallel Electron Beam Lithography using nc-Si (Nano Cristal Silicon) has been developed. It can drive a 100×100 electron emitter as an active matrix electron emitter with an innovative aberration correction scheme, a compensation scheme for electron beam intensity variation and a test circuit f…
木材は適切な管理を行えば持続的に生産可能な資源である。しかし，我が国の森林資源は，齢級分布が大きく偏っており，直近では資源余剰の状態だが，将来的には資源不足に陥る可能性がある。また，近年は，環境面の意識の高まりから，利活用における環境負荷の削減も重要な課題のひとつとなっている。木材について，環境負荷を削減しつつ，資源の利活用策を検討するためには，マテリアルフロー分析や，LCA手法を用いた環境影響分析が必要不可欠である。本総説では，木材の利活用におけるマテリアルフロー分析や，LCAによる環境影響分析を実施に関わる研究について概説するとともに，分析に必要なデータに関する情報の整理を試み，これらの内容に関する今後の課題について論じる。
Three sites of Benin’s clays from Gbedji-Kotovi, Massi-Sehoue and Zogbodomey were characterized in this study. Physicochemical and mineralogical analysis were performed by X-Rays Diffraction, chemical analysis, thermal analyses ATD/ATG, infrared IR, specific surface area and granulometry. Density of clayey particles,…
This paper presents the values of some physical and mechanical properties of bamboo culms grown in Italy and belonging to Phyllostachys Edulis and Phyllostachys Viridiglaucescens species. Specifically, the geometrical properties, the density, the moisture content, the compressive strength, the tensile strength, the be…
Abstract Bioabsorbable vascular stents in magnesium alloys provide an attractive alternative to standard stainless steel metal stents, because of their adequate radial force, high biocompatibility, low thrombogenicity and intrinsic dissolution in body fluids. Since magnesium is the major component of the alloys, high…
Medical radiation practitioners have been using lead aprons to protect themselves and others from uncontrolled X-ray radiation for almost a century. Lead impregnated vinyl aprons have excellent radiation shielding abilities. However, their shielding, comfort and design abilities overtime have been put to question by n…
In reality, nanotubes are not straight. In the present work, the buckling behavior of curved single-walled nanotubes (SWNTs), double-walled nanotubes (DWNTs) and multi-walled nanotubes (MWNTs) under axial compression is studied. The buckling analysis for the curved nanotube structures is performed by applying a nonloc…
Fermilab Main Injector is upgrading the accelerator to double the beam intensity from 24·10¹² protons to 48·10¹² protons, which brings the accelerator into a regime where electron cloud effects may limit the accelerator performance. In fact, an instability that could be caused by electron cloud effects has already bee…
The stress-strain behaviour of elastomeric polymers, such as polyurethane (PU), exhibit high rate dependency, stress-strain non-linearity, and high pressure dependency when compared to other construction materials. Since these polymers exhibit the potential to be applied as retrofitting and protective material for var…
Superconducting RF cavities made of bulk Nb has reached a breakdown field of about 200 mT which is close to the superheating field for Nb. As it was theoretically shown* a multilayer coating can be used to enhance the breakdown field of SRF cavities. The simple example is a superconductor-insulator-superconductor (S-I…
Polypyrrole-ZnO composites have been synthesized by chemical oxidation method using an anhydrous ferric chloride (Fecl3) as an oxidizing agent for different weight percentages of ZnO. The surface morphology has been studied by scanning electron micrograph (SEM) and structure by X-ray diffraction technique. The SEM ima…
This paper presents an overview of methods for recrystallizing 3-nitro- 1,2,4-triazol-5-one (NTO), with particular emphasis on methods for obtaining spheroidal particles with low porosity. The effects of selected solvents and surfactants on the recrystallization results was checked. Products in the form of spheroidal…
In order to facilitate studies of how dynamically changing element attributes affect the dynamics of the beam and beam losses, the functionality for dynamic kicks (DYNK) of SixTrack has been significantly extended. This functionality can be used for the simulation of dynamic scenarios, such as when crab cavities are s…
A new photoemissive electron source is being built in order to make use of the reduction of ensemble temperature in near band gap photoemission. It will operate at up to 200 kV bias voltage with NEA GaAs photocathodes. High bunch charges will be investigated in pulsed mode with respect to the conservation of emittance…
Drilling quality of medium density fiberboards (MDF) is significantly affected by delamination in furniture industry. The feed generated by a multi-spindle drilling machine tool is the so-called pneumatic pressure which provides a complex non-linear feed. The present study focuses on the machining parameters on delami…
Recently a number of novel drug delivery systems have emerged to minimize drug degradation and loss, to prevent harmful side-effects, to increase drug bioavailability and to achieve controlled and targeted drug delivery. Magnetic microsphere is one of the newer approach in pharmaceutical field due to their biocompatib…
2 Abstract: Fish such as common carp (Cyprinus carpio L), red snapper (Lutjanus sp.) and milkfish (Chanos chanos) play significant role in nutrient sources in Asian countries. The skin constituted of 4% of total body weight is usually discharged. The skin in fact contains of 50% collagen which can be useful as materia…
In this paper, we show how the Ordered Decomposition DAGs kernel framework, a framework that allows the denition of graph kernels from tree kernels, allows to easily dene new state-of-the-art graph kernels. Here we consider a quite fast graph kernel based on the Subtree kernel (ST), and we improve it by increasing its…
