Abstract Local delivery of physical energy, such as heat, is promising for the treatment target lesions without unintended distribution heat to other normal tissue. However, heating device must be equipped with an external power source or strong magnetic field operate device, and many them are too large placed inside body. In this regard, wireless, lightweight, flexible electronics can used miniaturization implantable devices. study, a induction (IH) reported that integrates inkjet‐printed...

Cathode spots of a low-pressure arc can remove oxide layers and evaporate impurities on metal surfaces. Removal the layer using cathode is expected to solve recent obstacles chemical mechanical cleaning methods. Various phenomena have been investigated for pre-treatment atmospheric pressure plasma spray (APPS). This study addressed relation initial surface roughness treated by low arc. The test pieces (SS 400) are compared with ones mechanically blasted Results show that sample surfaces most...
Challenges in the selective manipulation of functional groups (chemoselectivity) organic synthesis have historically been overcome using either reagents/catalysts that tunably interact with a substrate or through modification to shield undesired sites reactivity (protecting groups). Although electrochemistry offers precise redox control achieve unique chemoselectivity, this approach often becomes challenging presence multiple redox-active functionalities. Historically, electrosynthesis has...

In this paper, we propose an efficient route discovery scheme for mobile ad hoc networks called Hop-Wise Limited broadcast (HoWL). Since nodes do not identify the location of other nodes, some routing protocols proposed use network-wide broadcasts to discover a route. contrast, HoWL limits area by predicting current destination node using history hop counts previously used routes. We also introduce Characterized Environmental Indicators (CEI) which characterize environments nodes....

静岡県富士市内に所在するPS協同処理組合（16工場）の協力を得て，PSの化学組成，鉱物組成の週変化傾向を4週間にわたり詳細に検討した。具体的には，PS協同処理組合から排出された全体のPS焼却灰と，組合を構成する16工場から排出された各PSを，それぞれ週1回の間隔で合計4回採取し，化学組成の分析とゼオライト合成を行った。その結果，（1）各工場から排出されたPSの化学組成は変動するが，PS協同処理組合から排出された全体のPS焼却灰の化学組成は極めて安定していること，（2）ゼオライト原料として適するPSのみを選別したと仮定して，計算によって求めた化学組成は，PS協同処理組合から実際に排出された全体のPS焼却灰の化学組成と大きく変わらないこと，（3）このため，工業的にゼオライト合成を行う場合，ゼオライト原料として不適と判断したPSを分別する必要はなく，化学組成の安定した全体のPS焼却灰を原料として用いるのが，作業性，経済性の観点から適すること，等が明らかとなった。

静岡県の製紙産業は古紙の利用が盛んで, そのためペーパースラッジ (PS) の発生量が多く, その処分問題が早くから取り上げられてきた。PSは, 昭和40年代より様々な分野への利用法が開発され, 実用化されてきた。しかし, いまだに, 富士市内だけで年間100万t (水分65%換算) が排出され, セメント原料や製鉄保温材等に使われているが, 年間3万tの焼却灰が埋め立て処分されている。処分場確保の問題等もあり, 新しい用途開発が緊急の課題であることから, PS焼却灰を填料や顔料として紙にリサイクルする方法を研究した。その結果, 二酸化炭素 (排ガス) を導入してPS焼成することにより, 白色度も高く, 軟らかい焼却灰を得るPSの焼成条件を見出した。見出した焼成条件が実用焼却炉で再現できることを確かめた。PS焼却灰は鉄分除去を行いながら, 乾式粉砕と湿式粉砕により所定粒径まで粉砕した。鉄分除去を行ったにも係わらず上市されている填・顔料より赤味のある填料・顔料となった。PS焼却灰の特性を検討するとともに, 内添紙や塗工紙を実機製造した。塗工紙はマット調に仕上がったが,...
