An iteration method similar to the thin-wing-expansion method for the compressible flow has been proposed to solve the boundary layer flow past a flat plate. Using such an iteration, the first step of which is Oseen’s approximation, the boundary layer past a flat plate is studied. As proceeding from the first approximation to the second and third approximations, it is realized that our solution approaches to a well known Howarth’s bench mark one gradually. Hence, it is concluded that the usefulness of the present method has been confirmed.

A 26-year-old woman with no family history of dermatophytosis presented with pruritic erythema on the right palm (Fig. 1) in November 2002, 1 month after first noticing it. She had no lesions on the soles, toe webs, left palm, or nails. The erythema had been treated with topical steroids for 4 weeks, but had continued to expand. The erythema measured 42 mm ×36 mm, and was hyperemic and infiltrated unevenly. Its center showed no signs of healing, its periphery exhibited small vesicles, and its margin showed scales. On the scales, fungal hyphae and chains of arthroconidia were revealed by direct KOH test. The erythema was diagnosed as tinea manuum and was treated with topical terbinafine once daily. After several days of treatment, the erythema flared up and red papuloerythemas appeared on the back of both hands and on both forearms. Ten days after the first visit, the patient returned to our clinic for the treatment of newly developed eruptions. A trichophytin skin test produced an infiltrated erythema measuring 21 mm ×18 mm, confirming that the newly developed eruptions and exacerbated erythema on the right palm were due to a trichophytid reaction. Topical terbinafine was continued for the palm and fluocinolone acetonide ointment was applied on the newly developed eruptions on the arms from day 10 after the first visit. All the inflammatory eruptions subsided after 4 weeks of treatment and direct KOH test results were negative. The suspected cause of t inea manuum was the patient’s pet female four-toed hedgehog (Atelerix albiventr is) which she had kept for 4 years (Fig. 2). When she bought it from a local pet shop, it had desquamation on its body, but no lesions with loss of hair or quil l and no dermatitis. The scaling decreased gradually with treatment given by a v eterinarian. Three isolates of dermatophytes were obtained from the scale on the woman’s palm (KmU 4455), scale removed from the hedgehog (KmU 4459-1), and a fallen-out quill (KmU 4459-2). KmU 4455 gre

The authors report a 29 year old woman with marked atrophy of the cerebellum , medulla oblongata, and spinal cord, dementia, diffuse white matter abnormality on mRI, ragged red fibers, and R88C mutation in the human glial fibrillary aci dic protein (GFAP). mitochondria DNA (mtDNA) analysis showed a rare polymorphism at A8291G. This mtDNA polymorphism, which has been associated with limb girdle type mitochondrial myopathy, may modify the clinical symptoms of this juvenile form of Alexander disease with GFAP mutation.

在全球致力于实现碳中和的大背景下,生物质和废弃塑料的高值化利用已成为科研领域的研究热点.加氢脱氧反应(HDO),作为实现这一目标的重要途径之一,通过精准解离C-O/C-C键,为生产燃料和化学品提供了有效方法.在HDO过程中,C-O键的氢解及不饱和键的氢化是主要步骤,而C-C键的氢解则是需要避免的副反应.与简单的氢化反应相比,HDO过程需要具有双功能特性的催化剂,特别是当目标产物为含氧化合物时,催化剂的区域选择性至关重要.近年来,双金属催化剂在生物质及其衍生物以及含氧塑料废弃物和聚合物的HDO过程中的应用受到广泛关注.通过深入理解金属纳米颗粒与金属氧化物之间的协同作用和强相互作用,双金属催化剂的理性设计取得了显著进展.特别是,部分金属氧化物(如ReO_(x),WO_(x),moO_(x),FeO_(x))与贵金属(如Ir,Pt,Ru)之间存在的强相互作用,不仅促进了C-O键的断裂,还有效保留了C-C键,为催化剂的高活性和高选择性奠定了基础.通过调整催化剂组成、使用小比表面积的载体等方法,可以进一步优化催化剂性能.本综述聚焦于金属氧化物改性的贵金属催化剂在HDO反应中的最新研究进展,特别是总结了Ir、Pt和Ru基催化剂在HDO反应中的应用.由于这类催化剂的结构和性能能够精确控制,并且每种催化剂都具备独特的选择性,因此被广泛应用于生物质衍生物和塑料废弃物的HDO过程中.本文总结了双金属催化剂的结构特点、HDO反应机制、催化剂结构与催化性能之间的关联,以及这些催化剂在高附加值化学品生产中的实际应用.我们以甘油和1,2-丙二醇的氢解为模型反应,深入探讨了基于Ir、Pt和Ru的双金属催化剂的催化性能、结构特点和催化机理.这些催化剂在温和条件下实现了高效的氢脱氧反应,有效抑制了C-C键的断裂,并优化了化学选择性和区域选择性.双金属催化剂在生物质精炼和塑料/聚合物转化方面展现出广泛的适用性.本文还介绍了其在木质纤维素衍生原料、羰基化合物以及聚碳酸酯等塑料中的应用.然而,双金属催化剂的稳定性在实际应用中仍面临挑战,如金属烧结、浸出、积碳及金属-金属氧化物界面的重构等问题.因此,未来的研究重点是开发高效的再生方法和高度稳定的催化剂.综上所述,金属氧化物改性的贵金属催化剂在HDO反应中展现出巨大潜力.通过深入研究和优化,有望为生物质和塑料的高值化利用提供有效解决方案.本文旨在为双金属催化剂的理性设计和优化提供参考,以期推动生物质和塑料的高值化利用技术的进一步发展和应用.

Landfilling municipal solid waste incineration （mSWI） residue alkalizes the waste layer, causing a subsequent decrease in microbial activity and a delay in the decomposition of organic matter. In this study, efficiencies of neutralization of the leachate and organic matter decomposition in the waste layer in a column filled with mSWI residue using aeration and compost addition were evaluated. Total organic carbon （TOC） reduction in the waste layer is large at high oxygen flow rate （OFR）. To effectively accelerate TOC reduction in the waste layer to which compost was added, a high OFR exceeding that by natural ventilation was required. At day 65, the pH of the leachate when OFR was above 102 mol-O2/（day.m3） was lower than that when OFR was below 101 mol-Oz/（day.m3）. At the same OFR, the pH of waste sample was lower than that of waste sample with compost. Although leachate neutralization could be affected by compost addition, TOC reduction in the waste layer became rather small. It is possible that humic substances in compost prevent the decomposition of TOC in mSWI residue.
