乡品与乡里:六朝贵族制言说的展开及其新趋势

六朝时期,即便出身贵族也必须经过乡论和中正的“品藻”,获得“乡品二品”后才能成为官僚,进入清流官序。六朝史料中另有“二品才堪”现象,通过分析可以认为“二品才堪”并没有获得乡品二品,它反映出皇帝权力无法干涉“乡品二品”的授予这一历史事实。门阀贵族的存在反映出六朝与秦汉、宋元明清时期有着不同的历史特性,而六朝贵族体制源于地方乡里社会,则是其与重视血缘的欧洲和日本贵族制迥异之处。以皇权为核心的政治社会结构是中国历史发展的主轴,与此同时,六朝贵族制研究有助于我们从历史演进中去发现那些被皇权相对化的事物,从而客观、全面地勾勒中国历史发展的脉络和轨迹。

Trace Metals in Water Samples Taken from Azerbaijan Sector of Caspian Sea

The present study was conducted to investigate the heavy metal contents （As, Ba, Cd, Co, Cr, Cu, Ga, Mo, Mn, Rb, Pb, Cu, Ni, V, U and Zn） in seawater samples, which were collected at two c （5 and 100 m）, from 9 different sites of Azerbaijan sector of the Caspian Sea. The Agitent 7700x Series ICP-MS （inductively coupled plasma mass spectrometry） with HMI （high matrix introduction） system applied to analysis seawater. It was shown, the average concentrations of elements as Cr, Co, Cu, Mn, Pb and Zn in surface water slightly higher than their concentrations in depth water at 100 m. Practically it is not deference of the Mo, Rb and U average concentrations in surface and 100 m depth column water. There was little variation observed for nickel and vanadium. In contrast the concentrations of As, Ga and Ba in samples taken from 100 m, were significantly higher than the concentration in surface samples. Dependence concentration of elements from water columns depth can be explained in accordance with the geochemical system of classification of dissolved forms of elements in the sea water.

Affirming Art： Heidegger and the Sense of a Beginning

This essay offers a philosophical perspective that, in breaking with both the open and surreptitious dialectical method still so prominent in academic discourse, follows Heidegger in trying to conceive of a radically non-dialectical manner of approaching affirmation, negation, and neutrality. As with Heidegger, this is attempted through a turn towards art and the ＂emancipated contingency＂ that characterizes much creative production. In contrast to action and production within the knowledge economy, the creation of the artwork concerns a knowing of unknowingness （described by Maurice Blanchot as the neutral） that demands a rethink of action in relation to truth and errancy. Indeed, the very working of the work of art is conceived here as a truth that is precisely ＂set to work＂ （Heidegger） by errancy. Through a consideration of the essential difference between choice and decision and the different ＂beginning＂ of art that this suggests, the essay concludes with some reflections of the theme of art＇s fascination and the and the affirmation of the unknown.

Chemical Composition of the Edible Part and the Waste of Brachyuras

Flavorful meat and great economic importance, crabs and swimming crabs are appreciated throughout the Brazilian coast, where its waste is discarded by fishermen and consumers. In order to verify the centesimal composition, these animals caught in Sepetiba Bay （Rio de Janeiro, Brazil）, 20 samples of Ucides cordatus, Cardisoma guanhumi, Menippe nodifrons, Callinectes danae and C. exaperatus had their edible and waste parts （shells and hepatopancreas） analyzed in the Laboratory of Bromatology of the UFRRJ. The analysis revealed that the meat of crustaceans is protein （12.68% to 25.56%） and low in fat （0.37% to 0.67%）, sticking to a more demanding consumer market for thin products; the waste has already presented a protein content ranging from 15.75% to 27.64% and fat from 0.75% to 3.27%, with values of calcium （17.96% to 25.23%） and phosphorus （0.93% to 1.55%）, setting a precedent for use in animal feed through future studies in area.

Durum Wheat Bread： Old Sicilian Varieties and Improved Ones

In Mediterranean countries and particularly in Southern Italy, durum wheat （Triticum durum Desf.） is traditionally used for bread production. Market globalization has created, also in these regions, the spread of bread made with soft wheat flour （Triticum aestivum L.） standardizing this product flattening consumers＇ taste. With the aim of re-evaluating the old Sicilian local varieties, some landraces, chosen from the genebank of the institute, have been multiplied on farmers＇ fields to have enough material for making bread and for comparing this product with bread made by improved new varieties. Before milling in the pilot plant, the different wheats were characterized for their merceological indexes. The semolina obtained was analyzed for its chemical parameters. Rheological tests were conducted on dough and, finally, using standardized methods, one-variety breads were produced. On the bread slices, computerized image analysis was performed to measure colour and morphological parameters of crumb and crust. Sensory analysis, achieved through a descriptive profiling test, was conducted with trained judges using touch, fragrance and taste attributes for the different bread types. The different merceological, chemical and theological properties of raw material, grain and semolina were reflected in the breads prepared using old or improved varieties. Finally, the data obtained pointed out that the bread prepared with old and improved varieties can be clearly distinguished both by objective morphological parameters （image analysis） and by sensorial evaluations, for a potential traceability of typical product.

Homemade versus Commercial Jarred Baby Foods with Regard to Nitrites and Nitrates Content

This paper presents results of nitrites and nitrates determination in two types of baby foods： commercial products in jars and their homemade conventional counterparts. Nitrites levels in all analyzed samples were below of the detection limit （〈 0.9 mg/kg） of applied spectrophotometric method with Griess reagent. Nitrates contents in commercial products ranged： 9.1-38.1 mg/kg while in homemade baby foods levels between 26.6 mg/kg and 118.8 mg/kg were obtained. All the contents of nitrates were lower than the EU legislation maximum limit （200 mg/kg）. Comparison of each type of commercial product with its homemade counterpart baby food evidenced significant differences （p 〈 0.05） in average nitrates levels in favor of the first type. Apart from determining and comparing the levels of nitrates in the baby food samples also risk assessment for an average 6-months old infant to nitrates exposure was conducted. The estimated nitrates intake with a typical portion of 200g of baby food ranged between 6% and 25.7% of acceptable daily intake for commercial and from 18.0% to 80.3% for homemade ones.

Grout diffusion characteristics during chemical grouting in a deep water-bearing sand layer

This paper is devoted to application of ordinary kriging method in Choghart north anomaly iron ore deposit in Yazd province, Iran. In order to estimate the deposit, 2329 input data gained from 26 boreholes were used. Fe grade was selected as the major regional variable on which the present research has focused. All of the available data were changed to 12.5 m composites so that statistical regularization could be reached. Studies indicated that iron grade input data had single-population characteristics. To carry out ordinary kriging, a spherical model was fitted over empirical variogram. Then the model was verified through cross validation method and proved to be valid with a coherence coefficient of 0.773 between the estimated and real data. Plotting the empirical variogram in different directions showed no geometric anisotropy for the deposit. To estimate the Iron grade, ordinary kriging method was used according to which, all of the exploitable blocks with dimensions 20 m x 20 m x 12.5 m were block esti- mated within the estimation space. Finally tonnage-grade curve has been drawn and reserve classified into measured, indicated and inferred.

Development of a novel nano-biosorbent for the removal of fluoride from water

The study was designed to investigate the use of two sorbents namely(i) Fe3O4 nanoparticles immobilized in sodium alginate matrix(FNPSA) and(ii) Fe3O4 nanoparticles and saponified orange peel residue immobilized in sodium alginate matrix(FNPSOPR) as sorbents for fluoride removal from contaminated water. The synthesized nanoparticles were analyzed and characterized by dynamic light scattering, X-ray diffraction, vibrating sample magnetometry, and scanning electron microscopy with energy dispersive X-ray spectroscopy and Fourier transform-infrared spectrometry. The sorbent matrices were prepared in the form of beads and surface functionalized to enable enhanced sorption of fluoride ions. Batch sorption studies were carried out and the sorption isotherm and reaction kinetics were analyzed. Both the sorbents followed Langmuir model of isotherm and fitted well with Pseudo first order reaction. The maximum sorption capacity exhibited by FNPSA and FNPSOPR was58.24 mg·g-1and 80.33 mg·g-1respectively. Five sorption–desorption cycles exhibited 100%, 97.56%, 94.53%,83.21%, and 76.53% of regeneration of FNPSOPR. Accordingly, it is demonstrated that FNSOPR could be used as a promising sorbent for easy and efficient removal of fluoride from contaminated water with good reusability.The current work suggests a simple and effective method to remove fluoride from contaminated water.

Classification of Barley according to Harvest Year and Species by Using Mid-infrared Spectroscopy and Multivariate Analysis

In order to monitor malt quality in the malting industry, despite yearly variations in the barley quality, 394 barley samples were analysed using conventional （moisture, protein and B-glucan content） and mid-infrared Fourier transform spectroscopy FT-IR. The experimental dataset included barley from three harvest years, two barley species, 77 barley varieties, and two-row and six-row barley, from 16 cultivation sites. For each sample, the malt quality indices were also assessed according to European Brewing Convention （EBC） standards. Principal component analysis （PCA） was carried out on mean-centred, normalized and derivative spectra using 200/cm width spectral bands. The most informative spectral bands were observed in the 800-1,000/cm and 1,000-1,200/cm ranges. PCA revealed that barley harvested in 2010 and in 2011 had bands that were very close together, while 2009 harvest clearly displayed a difference in its quality. PCA made it possible to distinguish two species and confirmed that two-row winter barley quality was closer to two-row spring barley quality than to six-row winter barley. Results indicate that mid-infrared spectrometry （MIR） could be a very useful and rapid analytical tool to assess barley qualitative quality.

美国众议院关于“慰安妇”问题的立法活动研究

"慰安妇"问题一直被美国议员所关注,1997年美国议员威廉姆·里品斯基首次向美国众议院提交议案要求众议院关切"慰安妇"问题,从而在美国众议院开启长达十年之久关于"慰安妇"问题的立法活动。2007年美国众议院终于通过H.Res.121议案,该议案要求日本政府就"慰安妇"问题以明白和明确的方式正式承认、道歉和承担历史责任。H.Res.121议案获得通过,不仅意味着首次成功以立法形式确定日本性奴役"慰安妇"事实和划定日本政府在"慰安妇"问题上的责任,而且带动了世界范围内对"慰安妇"问题的立法活动。

Contribution to sample failure probability plot and its solution by Kriging method

To analyze the effect of the region of the model inputs on the model output,a novel concept about contribution to the sample failure probability plot(CSFP) is proposed based on the contribution to the sample mean plot(CSM) and the contribution to the sample variance plot(CSV).The CSFP can be used to analyze the effect of the region of the model inputs on the failure probability.After the definition of CSFP,its property and the differences between CSFP and CSV/CSM are discussed.The proposed CSFP can not only provide the information about which input affects the failure probability mostly,but also identify the contribution of the regions of the input to the failure probability mostly.By employing the Kriging model method on optimized sample points,a solution for CSFP is obtained.The computational cost for solving CSFP is greatly decreased because of the efficiency of Kriging surrogate model.Some examples are used to illustrate the validity of the proposed CSFP and the applicability and feasibility of the Kriging surrogate method based solution for CSFP.
