PM1.0 （fine particles, with diameter 〈 1 pm）, PM2.5 （fine particles, with diameter 〈 2.5μm） and PM10 （coarse particles, with diameter 〈 10 μm） were measured at 24-hour intervals near a high-traffic road in Hong Kong, from October 2004 to september 2005. Mass.c.ncentrations were determined for the three particle fractions, averaging for PM1.0, PM2.5 and PM10, respectively, 44.5±18.4, 55.4±25.5 and 81.3±37.7μg·m^-3, PM2.5 was 3.7 times the U.s. EPA＇s annual NAAQs of 15 μg·m^-3,. Overall, PM1.0 accounted for 44 to 69% （average 57%） of PM10, while PM2.5 accounted for 58 to 82% （average 71%） in this study. The particulate masses showed obvious seasonal patterns with high concentrations in cold seasons and low in warm seasons, especially high concentrations of PM2.5-10 during the cold seasons. Diurnal variations of mass.c.ncentrations of PM2.5 were determined during July, showing two major peaks in the morning and afternoon rush hours.

A comprehensive investigation on nonlinear vibration and bending characteristics of bio-inspired helicoidal laminated composite structures

引用

Applied Mathematics and Mechanics(English Edition) 2025年第1期46卷 81-100页

作者： s.sAURABH R.KIRAN D.sINGH R.VAIsH V.s.c.AUHAN school of Mechanical and Materials Engineering Indian Institute of Technology Mandi

Bio-inspired helicoidal composite laminates, inspired by the intricate helical structures found in nature, present a promising frontier for enhancing the mechanical properties of structural designs. Hence, this study provides a comprehensive investigation into the nonlinear free vibration and nonlinear bending behavior of bio-inspired composite plates. The inverse hyperbolic shear deformation theory(IHsDT) of plates is employed to characterize the displacement field, with the incorporation of Green-Lagrange nonlinearity. The problem is modeled using the c0finite element method(FEM), and an in-house code is developed in the MATLAB environment to solve it numerically. Various helicoidal layup configurations including helicoidal recursive(HR), helicoidal exponential(HE), helicoidal semi-circular(Hs), linear helicoidal(LH), and Fibonacci helicoidal(FH)with different layup sequences and quasi-isotropic configurations are studied. The model is validated, and parametric studies are conducted. These studies investigate the effects of layup configurations, side-to-thickness ratio, modulus ratios, boundary conditions, and loading conditions at different load amplitudes on the nonlinear vibration and nonlinear bending behaviors of bio-inspired composite plates. The results show that the laminate sequence exerts a substantial impact on both nonlinear natural frequencies and nonlinear bending behaviors. Moreover, this influence varies across different side-to-thickness ratios and boundary conditions of the bio-inspired composite plate.

将近30年来一直号称权威的发展范式如今正经受严重的压力。这一范式提出来时,曾被预言为能够自动成为现实,但终于未能产生预期的结果。为发展所付出的大量努力被引到了错误的方向,目标与效果南辕北辙。失败促使人们为这种毛病会诊,意在寻求其他出路。

Impact of climate change and Deforestation on stream Discharge and sediment Yield in Phu Luong Watershed, Viet Nam

Journal of Environmental science and Engineering 2011年第8期5卷 1063-1072页

作者： D.B. Phan c.c. Wu s.c. Hsieh Institute of Tropical Agriculture and International cooperation National Pingtung University of Science and TechnologyPingtung 912 Taiwan Department of soil and Water conservation National Pingtung University of Science and Technology Pingtung 912 Taiwan

The purpose of this paper is to apply ＂soil and Water Assessment Tool （sWAT）＂ model to assess the impacts of climate change and deforestation on stream discharge and sediment yield from Phu Luong watershed in Northern Viet Nam. Among the three climate change scenarios B 1, B2, and A2, representing low, medium, and high levels of greenhouse gas emission, respectively were set up for Viet Nam, the B2 scenario was selected for this study. Two land use scenarios （s1-2030 and $2-2050） were formulated combination with climate change in WsAT simulation. In B2 climate change scenario, mean temperature increases 0.7℃（2030） and 1.3 ℃ （2050）; annual rainfall increases 2.1% （2030） and 3.80% （2050） respect to baseline scenario. The results show that the stream discharge is likely to increase in the future during the wet season with increasing threats of sedimentation.

The purpose of this paper is to implement ＂soil and Water Assessment Tool （sWAT）＂ model to examine the effects of land use change scenarios; ass.c.ated with crop rotations and special cultivation techniques most susceptible to erosion; exert on runoff discharge and sediment yield from song cau catchment in Northern Viet Nam. All scenarios＇ simulations resulted in a decrease of soil losses and sediment yield comparing to the current land use status. sWAT s.c.essfully predicted soil losses from different HRUs that caused significant sediment yield, and it predicted explicitly the consequences of non-structural mitigation measures against erosion.

在资本主义体系内,大部分经济发展理论是假定该制度可以和谐地自我调整,并不考虑“区域”问题存在的可能性。这些理论认为,市场力量的自由发挥能保证工作向有劳动力的地方移动,或劳动力向工作机会多的地方迁移。由此会导致供需之间最终的和谐平衡。地区之间在利润、工资和就业方面的差异,即使存在,也被认为只是暂时的、由摩擦而生的,可以通过资本与劳动力的相应流动而自动趋于消失。新古典假说根据新古典理论,区域二元化或收入不平等的产生,只是均衡机制失灵的
