By the year 2050, the population of the United States is expected to reach over 418 million, while the global population will reach 9.6 billion. to provide safe food and fiber, agriculture must balance pesticide usage against impacts on natural resources. Challenges arise when storms cause runoff to be transported to aquatic receiving systems. Vegetated systems such as drainage ditches and constructed wetlands have been proposed as management practices to alleviate pesticide runoff. twelve experimental mesocosms （1.3 ±0.71 ± 0.61 m） were filled with sediment and planted with a monoculture of one of three wetland plant species （typha latifolia, Leersia oryzoides, and Sparganium arnericanurn）. three mesocosms remained unvegetated to serve as controls. All mesocosms were amended with 9.2 ± 0.8 μg/L, 12 ± 0.4 μg/L, and 3.1 ± 0.2 μg/L of atrazine, metolachlor, and diazinon, respectively, over a 4 hr hydraulic retention time to simulate storm runoff. Following the 4 hr amendment, non-amended water was flushed through mesocosms for an additional 4 hr. Outflow water samples were taken hourly from pre-amendment through 8 hr, and again at 12, 24, 48, 72, and 168 hr post-amendment. L. oryzoides and t. latifolia had mean atrazine, metolachlor, and diazinon retentions from B1%-55% for the first 4 hr of the experiment. Aside from S. arnericanum and atrazine （25% retention）, unvegetated controls had the lowest pesticide retention （17%-28%） of all compared mesocosms. While native aquatic vegetation shows promise for mitigation of pesticide runoff, further studies increasing the hydraulic retention time for improved efficiency should be examined.

在网络路由器或交换机以及企业存储设备等系统中的高速背板中,通信系统正在使速度限制超越传统的1Gbps大关.PCI或VME之类的共享总线拓朴结构曾用于背板应用,然而,它们在可伸缩性、带宽和距离方面受到限制,即使最新的PCI-X也只能在刚过1Gbyte/s的速率下使用.共享总线拓朴主要的限制因素在于高的I/O和有限的距离.由于任何一条引线或连线的损坏都将造成整个接口故障,所以可靠性也是共享总线的一个问题.共享总线的最大有效距离是18英寸.

在介绍性教科书、保护计划甚至基础著作中 ,常常将北极区和高山生物群系等同看待。高山和北极区生物群系无树的广阔区域 ,草本和非禾本科草本植物的初级生产力总量低 ,食物网单一。此外 ,除热带高山生境可能有例外 ,该两种环境都具有明显的季节性。但是 ,对于这些表面上相似的环境以前很少进行比较 ,而两者之间应具有明显的不同。我们假定 :如果环境相似 ,栖息在这些环境里的鸟类会对意外的应激刺激表现出相似的反应。相反 ,如果这些环境很不同 ,那么鸟类对剧烈应激的反应可进行调整以适应当地的不同环境 ,而不应一成不变。本文初步报道了青藏高原某些繁殖鸟类的肾上腺皮质反应 ,并与已发表的栖息于北极区苔原生态系统鸟类的数据进行了比较。白腰雪雀 (Onychostruthustaczanowskii)和棕颈雪雀 (Pyrgilaudaruficollis)被认为是高山代表物种 ,随着标准化捕捉 -处理 -抑制的应激刺激 ,它们表现出典型的血浆肾上腺皮质酮含量升高。但是 ,不同于许多北极区的代表物种 ,它们对应激的肾上腺皮质反应并无任何季节性变化。研究结果表示 :生活在高山和北极区环境下的鸟类物种可能具有激素反应以适应其生存环境所施加的生态挑战 [动物学报 49(1) :1～ 19,2 0 0 3]。

A multiphase microscopic interference system is designed to measure the height of cell which is important to the research of collective cell migration in physiology and medicine. this sys- tem can quantitatively measure cell height across a living monolayer without knowing the refractive index of cells. For the interference pattern, because the phases are all wrapped between - π to π, it is necessary to get the real phase through phase unwrapping,a method to restore the wrapped phase data of the object by using numerical calculations. three representative algorithms are selected to unwrap the interference pattern of ceils： branch-cut method, quality-guided method and network method. Although each of them can restore the phase, their performances are obviously different. We compare these methods and find that branch-cut method needs the smallest execution time and can obtain good unwrapped patterns when noises are not serious.

Arsenic contamination of global water supplies has come to the forefront in policy decisions in recent decades. However, the effects of arsenic on lower trophic levels of insects inhabiting contaminated ecosystems are not well understood. One approach to document both acute and sublethal effects of toxicants like arsenic is to assay them in combination with microbial pathogens to evaluate shifts in survival curves of the test organisms. Larvae of Culex quinquefasciatus and Culex tarsalis were reared in water containing 0 or 1 000μg/L of arsenate or arsenite. Fourth instars were then exposed to a range of doses of Bacillus thuringiensis subsp, israelensis （Bti） or Lysinibacillus sphaericus （Ls）, with shifts in lethal concentrations determined. Arsenic accumulation in 4th instars was also quantified, and a relative growth index （RGI） calculated for the treatments and compared to controls. Larvae of both species accumulated between 4 447 ± 169 ng As/g and 6 983 4- 367 ng As/g, though RGI values indicated accumulation did not affect growth and development. In all cases, the LC50＇s and LC90＇s of Cx. quinquefasciatus exposed jointly with arsenic and Bti/Ls were higher than Cx. tarsafis. Cx. tarsafis reared in arsenite showed a significant reduction in their Bti LC90 values compared to the control, indicating a sublethal effect of Bti. When exposed jointly with Ls, arsenite was more toxic than arsenate in Cx. tarsalis. Overall, these results indicate tolerance of these Culex species to arsenic exposures, and why this may occur is discussed.

Both neurons and glia throughout the central nervous system are organized into networks by gap junctions. Among glia, gap junctions facilitate metabolic homeostasis and intercellular communication. Among neurons, gap junctions form electrical synapses that function primarily for communication. However, in neurodegenerative states due to disease or injury gap junctions may be detrimental to survival. Electrical synapses may facilitate hyperactivity and bystander killing among neurons, while gap junction hemichannels in glia may facilitate inflammatory signaling and scar formation. Advances in understanding mechanisms of plasticity of electrical synapses and development of molecular therapeutics to target glial gap junctions and hemichannels offer new hope to pharmacologically limit neuronal degeneration and enhance recovery.
