Historically,Eastern China has the highest prevalence of anemia among adults in China. It is commonly believed that iron deficiency is the main cause of anemia in China. Iron fortified soysauce is used to prevent anemia. Findings from Jiangsu Nutrition Study suggest that diet is related to anemia in this region. However,iron deficiency is not the main cause. Micronutrients other than iron(e.g.,riboflavin) need to be considered in the prevention of anemia in the region.

土壤中嗪草酮迁移和降解的研究

中国环境科学 1997年第4期17卷 316-320页

作者：徐建民 w.C.Koskinen H.H.Cheng 浙江农业大学土化系

通过两季马铃薯大田试验，研究了嗪草酮在灌溉沙壤土中的消失和移动情况。结果表明，表层土壤中，嗪草酮施用后最初７～１５天内其含量急剧降低，此后随时间推移降低幅度平缓，１９９３年和１９９４年试验结束时的残留量分别为５．９μ... 详细信息

通过两季马铃薯大田试验，研究了嗪草酮在灌溉沙壤土中的消失和移动情况。结果表明，表层土壤中，嗪草酮施用后最初７～１５天内其含量急剧降低，此后随时间推移降低幅度平缓，１９９３年和１９９４年试验结束时的残留量分别为５．９μｇ／ｋｇ和２．３μｇ／ｋｇ。两年共采集的３７９个土样（分布在１５～７５ｃｍ各土层）中只有５个检测到有嗪草酮。１９９４年大田１３５ｃｍ土层处的水样中，嗪草酮的检测率高达６６％，检测浓度范围为０．０６～１５．８５μｇ／ｋｇ，平均浓度为１．９４μｇ／ｋｇ。相比较，嗪草酮在大田试验中的消失速率远大于实验室控制条件下的降解速率。

In this paper we describe a method for improving the angular resolution of the electron backscatter diffraction(EBSD) technique based on a correlative matching of EBSD *** image interpolation methods are used to detect shifts between selected regions of the EBSD patterns to an accuracy of one tenth of a *** data sets are used to show that such accuracy,combined with a small angle approximation in calculation of the rotation angle,allows determination of the misorientation between patterns to an accuracy of 0.01 *** method is tested on samples of both single crystal aluminum and recrystallized *** results demonstrate the accuracy and stability of the new method compared to the conventional method.

The activity concentration of naturally occurring radionuclides 40K, 226Ra and 232Th have been measured in different brands of fertilizer samples in Saudi Arabia using sodium iodide gamma spectrometry. The results of measurements showed that the mean (ranges) of specific activities for 226Ra, 232Th and 40K activities in the nitrogen, phosphorus and potassium fertilizers are 64 (35.8 - 120.7), 17 (3.2 - 56.8) and 2453 (744.9 - 4227.1) Bq/kg, respectively. with respect to organic fertilizers under investigation, the average radioactivity of 226Ra, 232Th and 40K are 42, 10 and 333 BqKg?1, respectively. Radium equivalent activity is not exceed 370 Bq/kg, the maximum permissible limit for radiation dose for all present samples. Average values of the three natural radionuclides measured in the brands of fertilizers used in Saudi Arabia are within the range of values reported in several other countries. This study could be useful as baseline data for radiation exposure to fertilizers and their impact on human health.

Deep troughs in Lake Superior support the hypothesis of Younger Dryas Boundary (YDB) comet impact 12,900 BP. The impact theory explains the megafauna extinction, a black mat across the Northern hemisphere, nanodiamonds, platinum and iridium, and the enigmatic Carolina Bays (CB). while the CB were thought to predate Clovis cultural remains, but this must now be seen as spurious as the CB occur on Long Island, an LGM terminal moraine & on end-glacial flood plains, according to Allen west. The CB sand rims are exceptionally pure quartz with large phenocrysts, and also they exude hydrogen (H). This suggests origin from deep granitic plutons, the granite typically being over-saturated with silica. when the Russian Kola Peninsula Superdeep Borehole had reached 40,000 ft, H was boiling from the borehole. This H is among volatiles copiously dissolved in the mantle, from the primitive solar nebula. The granite is from the Lake Superior Province. Lakes Superior, Michigan, Huron & Ontario have deep holes, reaching to below sea level. Bathymetry exhibits a ~145 km circular contour in Eastern L. Superior, where deep troughs occur, eroded in breccias infilling impact explosion cavities many kms deep, as much as 15 to 35 km, the comet fragments coming in from the Nw, with the holes lined up along the trajectory. This was an oblique impact with an extremely low angle of incidence, so the ejected granite quartz sands ended up in the CB along the Eastern seaboard principally.

China is rich in marine food fish resources. Among the fifty species of the marine food fishes, the Ribbonfish, Trichiurus haumela, the Small Yellow croaker, Pseudosciaena polyactis, and the Large Yellow croaker, P. crocea, are of primary importance, as the annual catches of each of these fishes in China exceed 100,000 tons. Annual catches of the other fishes vary greatly from species to species, ranging from several thousand tons to over ten thousand tons. As ichthyological studies were devoted mainly to the taxonomical works in China before 1949, the scientific data
