Manganese enhanced atrazine transformation by the fungus Pleurotus pulmonarius when added to a liquid culture medium at concentrations of up to 300 microM. Both N-dealkylated and propylhydroxylated metabolites accumulated in the culture medium, with the former accumulating to a greater extent than did the latter. Lipid peroxidation, oxygenase and peroxidase activities, and the cytochrome P-450 ...

Staphylococcus aureus formed an electron transport system when exponentially growing cells were aerated. Formation of the electron transport system occurred concomitantly with increases in the phospholipids and the carotenoids. The addition of piperonyl butoxide or benzo(a)pyrene at the onset of aeration (i) slowed the formation of the electron transport system, (ii) both inhibited cytochrome o...

Organic-inorganic hybrid perovskite materials have recently been identified as a promising light absorber for solar cells. In the efficient solar cells, the perovskite active layer has generally been fabricated by either vapor deposition or two-step sequential deposition process. Herein, electrochemically deposited PbO film is in situ converted into CH3NH3PbI3 through solid-state reaction with ...

Three commercially available backpack sprayers were evaluated with Aqualuer® 20-20 (20.6% permethrin, active ingredient; 20.6% piperonyl butoxide, technical) against caged adult Aedes aegypti in semifield trials in northeastern Florida. Two battery-powered sprayers, Birchmeier and Hudson, were compared with the standard hand-pump SOLO 425 sprayer, which is currently used in pest management oper...

BACKGROUND Continuous treatment is recommended for patients with moderate-to-severe psoriasis; however, treatment may need to be interrupted in routine clinical practice. OBJECTIVE To assess outcomes in patients continuously treated with ixekizumab versus those who interrupted therapy and were subsequently retreated with ixekizumab (IXE). METHODS This analysis used data pooled from two phas...

1 緒 言 PBO(ポリパラフェニレンベンゾビスオキサゾ-ル) 繊維は,繊維強化複合材料の有機系強化繊維の一つであ り,炭素繊維に匹敵する強度・弾性率を有し,有機繊維 中最高の耐熱性・難燃性を示す事から,FRPの次世代の 強化繊維としての用途展開が期待されている.1), 2) しかしながら,PBO繊維は,繊維/樹脂間の界面強度 が不十分であり,この界面強度は FRPの様々な力学的特 性に大きく影響するため,3)PBO繊維の FRPの強化繊維と しての優れた特性を最大限に活かすためには,界面強度 向上を目的とした繊維表面改質法の研究が不可欠となっ てくる. 現在,繊維/樹脂間の界面強度の向上を目的として, 様々な表面改質法が試みられている.中でも低温プラズ マ処理は,ドライプロセスで低公害であり,繊維自身の 物性を損なうことなく,親水性の官能基を表面に効率的 に付与できるといった利点を...

A field strain of the German cockroach (Melia), collected from the kitchen of a hotel in Kuala Lumpur, Malaysia demonstrated moderate resistance to bendiocarb and low resistance to propoxur and deltamethrin when tested with modified W.H.O. glass jar method. Low resistance was also detected when the strain was tested with DDT. Resistance level to bendiocarb and deltamethrin was partially suppres...

Long lasting pyrethroid treated bednets are the most important tool for preventing malaria. Pyrethroid resistant Anopheline mosquitoes are now ubiquitous in Africa, though the public health impact remains unclear, impeding the deployment of more expensive nets. Meta-analyses of bioassay studies and experimental hut trials are used to characterise how pyrethroid resistance changes the efficacy o...
