Thin-film analyses of silicate standards at 200 kv : the effect of temperature on element loss

Preliminary data is presented on a detailed statistical analysis of k-factor determination for a single class of minerals (amphiboles) which contain a wide range of element concentrations. These amphiboles are homogeneous, contain few (if any) subsolidus microstructures and can be readily prepared for thin film analysis. In previous studies, element loss during the period of irradiation has been assumed negligible for the determination of k-factors. Since this phenomena may be significant for certain mineral systems, we also report on the effect of temperature on k-factor determination for various elements using small probe sizes (approx.20 nm).

Early life determinants of atopy : A 20-year prospective follow-up study on unselected, healthy newborns

Atopy-related allergic diseases, i.e. allergic rhinoconjunctivitis, atopic dermatitis and asthma, have increased in frequency in the industrialized countries. In order to reverse this trend, effective preventive strategies need to be developed. This requires a better understanding of the early-life events leading to the expression of the atopic phenotype. The present study has aimed at defining early-life factors and markers associated with the subsequent development of allergic diseases in a cohort of 200 healthy, unselected Finnish newborns prospectively followed up from birth to age 20 years. Their mothers were encouraged to start and maintain exclusive breastfeeding as long as it was nutritionally sufficient for the infant. Consequently, all the infants received some duration of exclusive breastfeeding, 58% of the infants were on exclusive breastfeeding for the first 6 months of life, and 18% received this feeding at least for the first 9 months. Of the infants, 42% had a family history of allergy. After the first year of follow-up, the children were re-assessed at ages 5, 11 and 20 years with clinical examination, skin prick testing, and parental and personal interviews. Exclusive breastfeeding for over 9 months was associated with atopic dermatitis and symptoms of food hypersensitivity at age 5 years, and with symptoms of food hypersensitivity at age 11 years in the children with a familial allergy. Subjects with allergic symptoms or a positive skin prick test in childhood or adolescence had lower retinol concentrations during their infancy and childhood than others. An elevated cord serum immunoglobulin E concentration predicted subsequent atopic manifestations though with modest sensitivity. Children and adolescents with allergic symptoms, skin prick test positivity and an elevated IgE had lower total cholesterol levels in infancy and childhood than the nonatopic subjects. In conclusion, prolonging strictly exclusive breastfeeding for over 9 months of age was not of help in prevention of allergic symptoms; instead, it was associated with increased atopic dermatitis and food hypersensitivity symptoms in childhood. Due to the modest sensitivity, cord serum IgE is not an effective screening method for atopic predisposition in the general population. Retinol and cholesterol concentrations in infancy were inversely associated with the subsequent development of allergic symptoms. Based on these findings, it is proposed that there may be differences in the inborn regulation of retinol and cholesterol levels in children with and without a genetic susceptibility to atopy, and these may play a role in the development of atopic sensitization and allergic diseases.

Flood of September 20-23, 1969 in the Gadsden County area, Florida

The center of low pressure of a tropical disturbance which moved northward in the Gulf of Mexico, reached land between Panama City and Port St. Joe, Florida, on September 20, 1969. This system was nearly stationary for 48 hours producing heavy rainfall in the Quincy-Havana area, 70-80 miles northeast of the center. Rainfall associated with the tropical disturbance exceeded 20 inches over a part of Gadsden County, Florida, during September 20 through 23, 1969, and the maximum rainfall of record occurred at Quincy with 10.87 inches during a 6-hour period on September 21. The 48-hour maximum of 17.71 inches exceeded the 1 in 100-year probability of 16 inches for a 7-day period. The previous maximum rainfall of record at Quincy (more than 12 inches) was on September 14-15, 1924. The characteristics of this historical storm were similar in path and effect to the September 1969 tropical disturbance. Peak runoff from a 1.4-square mile area near Midway, Florida, was 1,540 cfs (cubic feet per second) per square mile. A peak discharge of 45,600 cfs on September 22 at the gaging station on the Little River near Quincy exceeded the previous peak of 25,400 cfs which occurred on December 4, 1964. The peak discharge of 89,400 cfs at Ochlockonee River near Bloxham exceeded the April 1948 peak of 50,200 cfs, which was the previous maximum of record, by 1.8 times. Many flood-measurement sites had peak discharges in excess of that of a 50-year flood. Nearly $200,000 was spent on emergency repairs to roads. An additional $520,000 in contractual work was required to replace four bridges that were destroyed. Agricultural losses were estimated at $1,000,000. (44 page document)

Un uso metafórico del vino en Aristófanes: las vinosas treguas de Acarnienses, 186-200

[ES] Aristófanes es un autor que muestra en sus obras una predilección especial por el vino, al que hace numerosas alusiones de todo tipo, relacionándolo con la celebración y la fiesta. Podemos destacar en particular algunos usos metafóricos en los que se muestra la estrecha relación que existe entre éste y la paz, con la que en cierta manera puede llegar a identificarse. Tal es el caso de un pasaje de Aristófanes (Acarnienses, 186-200) en el que las diversas propuestas de tregua se presentan como si fueran vinos de diversas añadas que el protagonista debe catar.

Femtosecond optical Kerr effect study of Ge(10)AS(40)S(30)Se(20) film

The results of the femtosecond optical heterodyne detection of optical Kerr effect at 805 nm with the 80 fs ultrafast pulses in amorphous Ge10As40S30Se20 film is reported in this paper. The film shows an optical non-linear response of: 200 fs under ultrafast 80 fs-pulse excitation and the values of real and imaginary parts of non-linear susceptibility chi((3)) were 9.0 X 10(-12) and -4.0 X 10(-12) esu, respectively. The large third-order non-linearity and ultrafast response are attributed to the ultrafast distortion of the electron orbits surrounding the average positions of the nucleus of Ge, As, S and Se atoms. This Ge10As40S30Se20 chalcogenide glass would be expected as a promising material for optical switching technique. (c) 2005 Elsevier Ltd. All rights reserved.

神农架的植被及其1：200，200植被图的编制

神农架位于湖北省西部，长江以北、汉水以南的广阔地带，属北亚热带向暖温带的过渡区域。本文依据该地区所处地理位置的植被分布规律等资料，绘制了1：20万的植被复原图。并在此基础上，运用ERDAS imagine 8.4和Maplnfoprofessional 6.0软件，分别对神农架地区的TM影像（5、4、3波段）进行监督分类及目视解译，同时结合野外的样方调查，绘制了神农架地区1：20万的植被类型图，并建立了相应的属性数据库。最后，根据野外的GPS定位点对制图精度进行了Kappa检验。 制图结果表明，制图区总面积3476.67 km2，共计504个斑块。据统计，林地面积2607.45 km2，森林覆盖率75%;山地灌丛及亚高山灌丛总面积358.62 km2，占总面积的10.3%：草甸面积156.84 km2，占4.51%。自然植被划分为10个植被型，46个群系，以及农田（包括居民点）和茶园两种农业土地利用类型。其中针叶、落叶阔叶混交林面积最大（6个群系），约908 km2，占总面积的26.12%;其它依次为落叶阔叶林（1 1个群系），针叶林（4个群系），常绿阔叶林（3个群系），山地灌丛（5个群系），常绿阔叶、落叶阔叶混交林（3个群系），亚高山灌丛(6个群系)，草甸（4个群系）以及亚高山针叶林（3个群系）等。另外，两种农业土地利用类型面积共计430 kn12，占总面积的12.37%。 植被类型图与复原图叠加分析表明：①常绿阔叶林的理论分布区域，由常绿阔叶林，常绿、落叶阔叶混交林等7种植被型以及农田（含居民点）等土地利用类型共同组成。因处低海拔区域，人口集中，所以农田（含居民点）分布最广，所占面积最大，占到该区域面积的35.28%;加上长期的人为干扰，常绿阔叶林面积缩小至48.76 krr12，占到该区域面积的13.93%;②常绿、落叶阔叶混交林的理论分布区域内，因干扰后落叶阔叶林恢复较快，逐渐占据优势。另外，该区域海拔较低，人类活动也较频繁，农田（含居民点）面积仍有相当的比例;③针阔混交林理论分布区海拔位置高，人为活动影响少，原地带性植被保存较好，分布面积最大;其余部分为落阔林等7种植被型共同组成。④针叶林理论分布区域应是以巴山冷杉林为单优种的亚高山针叶林带，但因历史上的皆伐及火烧等原因，现面积仅有17 kfr12，占该区域的19.8%，其余则为亚高山灌丛及亚高山草甸所替代。

Measurement of the Bottom Quark Contribution to Nonphotonic Electron Production in p plus p Collisions at root s=200 GeV

The contribution of B meson decays to nonphotonic electrons, which are mainly produced by the semileptonic decays of heavy-flavor mesons, in p + p collisions at root s = 200 GeV has been measured using azimuthal correlations between nonphotonic electrons and hadrons. The extracted B decay contribution is approximately 50% at a transverse momentum of p(T) >= 5 GeV/c. These measurements constrain the nuclear modification factor for electrons from B and D meson decays. The result indicates that B meson production in heavy ion collisions is also suppressed at high p(T).

A kind of microporous with size of 0. 661 4 nm X 0. 318 9 nm was formed in the crystal structure.
