The effects of the molecular weight (MW) and charge density (CD) of cationic polyacrylamide (CPAM) on sludge dewatering and moisture evaporation were investigated in this study. Results indicated that in sludge conditioning, the optimum dosages were 10, 6, 6, 4, and 4 mg g(-1) CPAM with 5 million MW and 20% CD, 5 million MW and 40% CD, 3 million MW and 40% CD, 8 million MW and 40% CD, and 5 mil...

Nateglinide(NTG), Repaglinide(RPG), and Glimepiride(GMP) are antidiabetic drugs. These antidiabetic drugs are poorly soluble in water, which affect the bioavailability. In the present work, complex formation of all the three drugs with b-cyclodextrin (b-CD) and Hydroxy propyl bcyclodextrin (HPb-CD) and then the possibility of improving the solubility of NTG, RPG and GMP by complexation with b-C...

1.はじめに CGで現実感のある画像を生成する技術は、いかにして物体を 忠実に表現するかの技術である。物体を特徴付ける要素として は、大きく分けて、物体の形状と、物体表面の色情報や光学属 性などの表面属性がある。物体の表面属性を表現する場合、一 般的には、バンプマッピングなどのさまざまなマッピング手法 がとられている。CGデザイナがマッピングに利用できる素材と しては、市販の CD-ROM やインターネット経由で入手できる素 材集、およびテクスチャ生成のプログラムから出力されるデー タなどがある。 本報告で取り扱う石畳を表現する場合、CGデザイナが路面の 敷石を1つ1つモデリングして表現することが理想ではある が、大変な労力を要するため現実的ではない。一方、石畳の写 真素材を路面にマッピングして表現することも可能であるが、 以下のような問題が生ずる。 ・テクスチャ全体として凹凸が激し...

Sedum alfredii is a well known cadmium (Cd) hyperaccumulator native to China; however, the mechanism behind its hyperaccumulation of Cd is not fully understood. Through several hydroponic experiments, characteristics of Cd uptake and translocation were investigated in the hyperaccumulating ecotype (HE) of S. alfredii in comparison with its non-hyperaccumulating ecotype (NHE). The results showed...

BACKGROUND AND OBJECTIVES Epidemiological evidence for the role of polyunsaturated fatty-acids (PUFA) in Crohn's disease (CD) is unclear, although the key metabolite leucotriene B4 (LTB(4)) is closely linked to the inflammatory process. We hypothesized that inherited variation in key PUFA metabolic enzymes may modify susceptibility for CD. METHODS AND PRINCIPAL RESULTS A case-control design w...

BACKGROUND A number of studies have shown that the chronic stress of caring for persons with dementia can have significant immunological consequences as demonstrated by the down-regulation/dysregulation of the cellular immune response. METHODS Utilizing flow cytometry to measure the percentages and absolute numbers of CD-4(+) and CD-8(+) T lymphocytes producing the cytokines indicative of Th-...
