Capital como Droga, Trabalho como Vício: subjetividade, euforia e depressão na pós-modernidade

O objetivo central deste estudo é examinar as novas formas de subjetivação e de mal-estar engendradas pelas exigências da sociedade do trabalho no contexto do capitalismo contemporâneo. A emergência de uma nova e perversa forma de sociabilidade e de uma subjetividade ligada a ela está intrinsecamente associada às transformações estruturais da sociedade capitalista e suas atuais condições da acumulação de capital. Considerando o caráter social e histórico da sociedade capitalista, do sujeito e da subjetividade, o foco deste trabalho deve ser o sujeito interpelado pela ideologia, clivado pelo inconsciente e individualizado pelo mercado. Busco, portanto, articular pontos teóricos entre os conceitos de ideologia, fetiche e inconsciente referenciados no materialismo histórico e na psicanálise. Ao apresentar o Capital como droga e o Trabalho como vicio, pretende-se de forma alegórica desvelar os impasses e sintomas de um sistema em crise que, apesar das sucessivas tentativas de recuperação, colapsa historicamente, levando sua dinâmica perversa aos limites do insuportável. Ao subordinar a reprodução da vida ao trabalho assalariado, ao mesmo tempo em que para se reproduzir tem sistematicamente de aboli-lo, o capitalismo engendra, na sua crise estrutural, uma das mais sofisticadas formas de dominação, sujeição e exploração: a utilização dos componentes do psiquismo e da subjetivação em nome dos interesses da ordem mercantil. No mundo globalizado pelo mercado, vem aumentando o uso de drogas lícitas, fruto ou não de prescrição médica, como um recurso para inibir todo tipo de mal-estar e impasse psíquico ou reações indesejáveis que possam comprometer a adequação dos indivíduos aos padrões da produtividade, a permanência no ambiente de trabalho, bem como o enfrentamento de conflitos e frustrações inerentes à condição humana. Essa manipulação química da subjetividade potencializa-se na atualidade, expandindo globalmente a drogadicção, no sentido amplo do termo, privando o sujeito da capacidade de pensar. Ela aponta também para as impossibilidades de o sujeito desenvolver suas faculdades ativas e criativas, assim como o diálogo com o outro, o que nos conduz cada vez mais a atitudes de intolerância e violência ou estados compulsivos e depressivos. Ao contrário do que o capitalismo podia propiciar em seu período de ascensão, os modos de inclusão imaginária engendrados pelo capitalismo pós-moderno estão baseados no consumo conspícuo e no gozo imediato, implicando novos contornos para o sofrimento psíquico, agora marcado por transtornos narcísico-identitários e saídas não-representacionais. A partir dessa reflexão, busco a crítica do conceito de sujeito configurado pelo trabalho e pelo psicologismo, que tem contribuído para práticas legitimadoras de exclusão no interior da própria psicologia. Esta crítica representa um compromisso ético-político pela desalienação do sujeito e pela superação do capitalismo, aqui entendido como um sistema que produz mercadorias e viciados em drogas.

Mortality estimates of Indian ribbon fish Trichiurus lepturus off Maharashtra coast

In view of its new found status in export market, ribbon fish resources need to be continually monitored. Mortality, one of the important parameter is reported for the Indian ribbon fish Trichiurus lepturus Linnaeus in the present communication. The average annual instantaneous rate of total (Z), natural (M) and fishing mortality coefficient (F) were estimated as 2.66, 0.77 and 1.89 respectively for the 1995 to 1997 period. The exploitation rate (U) and exploitation ratio (E) were estimated as 0.66 and 0.71 respectively, which is beyond the optimum thrust reduction in the fishing effort for this stock along the Maharashtra coast is necessary.

Preliminary investigations on the population dynamics of Otolithes ruber (Sciaenidae) on Sofala Bank, Mozambique

Catch length-frequency data of Otolithes ruber (Schneider, 1801) obtained from the "Projecto de Pesca Experimental da RDA" on Sofala Bank, Mozambique, in 1987 were used to estimate growth parameters, mortalities and exploitation rates. The yield-and biomass-per-recruit analyses based thereon suggest that the stock is overfished.

Regulation: A Burden in Biopharmaceutical Industry? The Case of EU-Risk Management Plans

The generation of new medicinal products is both a contributor to global economic growth and a source of valuable benefits to human health. Given their direct responsibility for public health, regulatory authorities monitor closely both the development and exploitation of the underlying technologies and the products derived from them. The manner in which such regulation is implemented can result in regulators constraining or facilitating the generation of new products. This paper will study as an example the impact of EU Risk Management Plans (EU-RMPs), which have been mandatory for the approval of new medicines since 2005, on both the industry and regulatory authorities. In interviews, the responses of those who had experience of the implementation of EU-RMPs were mixed. Although the benefits of a more structured and predictable approach to the evaluation of risk were appreciated, some respondents perceived the regulation as an excessive burden on their organisations. The exploration of factors that influence how EU-RMP regulation affects individual firms provides new insights for both regulators and managers, and demonstrates one aspect of the complexity of the process by which new medicinal products are brought to market.

Identification of differentially expressed immune-relevant genes in Chinese soft-shelled turtle (Trionyx sinensis) infected with Aeromonas hydrophila

Expressed sequence tag (EST) analysis is an efficient tool for gene discovery and profiling gene expression. Aeromonas hydrophila, a ubiquitous waterborne bacterium, is one of the most frequent pathogens isolated from diseased aquatic organisms. In order to understand the molecular mechanism of anti-bacteria immune response in reptile, we have investigated the differentially expressed genes in Chinese soft-shelled turtle (Trionyx sinensis) experimentally infected with A. hydrophila by suppression subtractive hybridization (SSH). Forty-two genes were identified from more than 200 clones, of which 25 genes are found for the first time in reptiles, and classified into 6 categories: 18 in defense/immunity. 4 in catalysis, 2 in retrotransposon; 2 in cell signal transduction, 5 in cell metabolism, 10 in protein expression, and 1 in cell structure. Of the 42 differentially expressed genes, 6 genes, IL-8, serum amyloid A (SAA), CD9, CD59, activating transcription factor 4 (ATF4) and cathepsin L genes, were further observed to be up-regulated in the infected turtles by virtual Northern hybridization and RT-PCR assays.

有机质谱裂解规律及智能解析方法研究

本学位论文分为四个部分，第一部分报道了用串联质谱快速分析合成药物中的微量杂质成分以及分析中药材中的化学成分。第二部分报道了通过质谱和串联质谱发现并合成新型的PdPincer 催化剂，同时对其活性进行测试。第三部分为串联质谱自动解析软件的设计及应用。第四部分概述了应用在质谱中的各种碎裂方式。 第一部分首先总结了5-溴粉防己碱及其类似物的裂解规律，并以此为根据推测出2 个微量杂质的结构。随后针对无患子（Sapindus mukurossi Gatren.）中的皂苷成分，由ESI-QTOF 得到各个皂苷成份的高分辨质量数据进而得到其分子式，然后利用ESI-IT 电喷雾串联质谱对无患子总皂苷中各皂苷成分的结构进行进一步的鉴定。进而以同样的方式，先通过ESI-QTOF 得到黄山药（Dioscoreapanthaica）总皂苷中各个组分化合物的分子式，然后对已有的薯蓣皂苷标准品做串联质谱分析，以得到该类化合物的裂解规律并给出解析该类化合物的流程图。在此利用计算化学的方法讨论了离子的丰度与裂解活化能之间的关系。然后应用APCI-MS/MS 方法探讨了四对同分异构体和几个已知的化合物，并最后用液质联用对其进行确认，同时还给出了4 个未知化合物的可能结构。 第二部分报道通过质谱和串联质谱发现并合成新型的PdPincer 催化剂，同时对其活性进行测试。钯催化的交联反应是有机合成中C-C 键形成的最有效的方法，且硫脲是一类对空气和水都稳定的化合物，因此我们设计并合成了一系列的硫脲钯催化剂并得到了很好的催化活性。我们在对其中一类环状双硫脲化合物进行质谱实验的时候，在正离子模式下发现了反常的[M.H]+，通过串联质谱进一步确定了它是一种新型的PdPincer 结构。我们将其合成出来并通过X-ray 衍射实验确定了它的结构。同时测定其催化活性并与未形成pincer 的类似物进行比较发现该类化合物具有较宽的底物适用性。 第三部分为串联质谱自动解析软件的设计及应用。通过前面两部分的启示，独立设计开发了AuMass（1.0）。其算法是：先通过查找特殊的碎片离子，中性丢失或碎片离子质量差来确定某类化合物的骨架结构，然后利用该类化合物的自动解析流程来对其周边取代基进行确认。通过它快速地对白芍中的化学成分进行解析，并对未知的化合物进行了推测。为了增加它的解析能力，我又对其它类型的化合物裂解规律进行总结，并给出了自动解析流程。实践证明该软件具有相当好的应用价值。 第四部分综述了应用在质谱上的各类母离子的碎裂技术。这里包括了碰撞诱导裂解（CID）、光诱导碎裂（LID）、电子捕获裂解/电子转移裂解（ECD/ETD）、红外多光子解离（IRMPD）、黑体辐射解离（BIRD）和PQD 裂解技术。 This dissertation consists of four chapters. The first chapter reports the rapidanalysis of trace impurities from synthetical medicine and analysis of the chemicalconstitutents from Chinese herb medicines. The second chapter elaborates the studieson the discorvery and synthesis of new type of Pd Pincer catalyst by using MS andtandem MS together with the testing of its catalyst activity. The third chapter dwellson the designation and development of automatic tandem mass spectrometry analysissoftware. The last chapter presents a review on the dissociation technique of massspectrometry. The first chapter reports the rapid analysis of trace impurities from synthesismedicine and analysis of the chemical constitutents from Chinese herb medicines. The fission mechanism of 5-bromotetrandrine was obtained by analysis of the dissociationpathways of major product, by using which the possible structure of the two traceimpurties was assumed. There are lots of saponins in Sapindus mukurossi. Except forthe good spumescence and decontamination，it possesses the bioactivity of antigenand antitch. First of all, the high resolution mass information was obtained by ESI-QTOF. Hence the possible molecular formulars were acquired too. Then weconducted the further detection of the structures of its saponins by using ESI-ITtechnology. In the same manner, first the molecular formulars of every constituentfrom Dioscorea panthaica in total saponins were obtained by ESI-QTOF, and thenacquired the fission mechanism of this type of compounds by tandem massexperiment on a series of known and available saponins. In the same time, theanalysis flowchart was concluded. Here the relationship between the ion intensity andthe corresponding dissiociation activation energy was studied by computer chemistry.Then the four pairs of isomers were differentiated by APCI-MS/MS, as well as thecharacterization of known and unknown compounds. The assumption was confirmed by HPLC-MS/MS. Among them the possible structures of four unknown saponinswas presented. The second part was discovery and synthesis of a new type of Pd pincer catalystby MS and tandem MS. The coupling reaction catalyzed by Pd is the most effectivemethod in C-C formation in organic synthesis. Apart from that, thiourea is type ofcompounds that are stable to atmosphere and moisture. Hence we designed a series ofPd thiourea catalysts. Some of them show the excellent catalyst activity. The abnormalparent ion [M.H]+ was founded in positive ESI mode when we conduct some massspectrometry experiments on the bicyclical thiourea Pd complex. The structure wasproposed by mass and tandem mass spectrometry. Because it was a new type of pincer,we want to test its catalyst activity. So the Pd pincer was synthesized and the detailstructure was obtained by x-ray experiment. It shows the more fitness in catalysis ofSuzuki reaction by comparison with the analogue. The third chapter dwells on the design and development of automatic tandemmass spectrometry analysis software. Inspired by the former two chapters, theAuMass (version 1.0) was developed. Its algorithm is: first check the diagnostic ion,diagnostic neutral loss or diagnostic ions mass intervals in database to find out whatthe analyst’s skeleton belongs to, then identify the peripheral functional group by thecorresponding analysis flowchart. The chemical constituents of Paeonia lactiflorawere identified rapidly by using AuMass. To increase the analysis ability, the othertypes of compounds from Chinese herbs was concluded. Actually, the software isproven to have the much valuable application. The last chapter presented the review on the some kinds of fission technique ofmass spectrometry. It involves the collision induced dissociation (CID), laser induceddissociation (LID), electron capture dissociation/electron transfer dissociation(ECD/ETD), infrared multiple photons dissiociation, black body irraditiondissociation and PQD fission technique from Finnigan.

青藏高原栽培青稞遗传多样性研究

青稞，是我国藏区居民对裸大麦的称谓，它不仅是藏民的主要食粮、燃料和牲畜饲料，而且也是啤酒、医药和保健品生产的原料；青稞不仅为藏区人民的健康和经济发展做出了很大的贡献，而且对人类健康和社会经济的可持续发展都有重要的意义。青藏高原是我国及世界上青稞分布和种植面积最大的地区，资源极其丰富。虽然从经典遗传直到分子标记对我国大麦遗传多样性都有研究，但研究手段、数量仍然不够深入，对我国大麦资源遗传多样性研究的信息非常有限，不能很好地满足大麦遗传研究和育种应用的需要，尤其是对西藏栽培大麦的遗传多样性的研究还只是刚刚开始，关于栽培青稞多态性的研究报道很少。本研究采用SSR标记和蛋白质电泳两类技术，从SSR标记位点、单体醇溶蛋白、B组醇溶蛋白和淀粉粒结合蛋白（SGP）等四个方面对我国青藏高原栽培青稞的遗传多样性进行了综合评价。 SSR标记具有基因组分布广泛、数量丰富、多态性高、容易检测、共显性、结果稳定可靠、实验重现性好、操作简单、经济、易于高通量分析等许多优点，被认为是用于遗传多样性、品种鉴定、物种的系统发育、亲缘关系及起源等研究的非常有效的分子标记。本研究采用SSR标记分析了64份青藏高原栽培青稞的遗传多样性，同时评估SSR标记在我国大麦育种和品种鉴定中的应用潜力。选择了30个已知作图位点SSR标记，其中25个标记与重要性状的控制位点连锁紧密。选择的30个SSR标记，5个未得到很好的扩增产物，3个无多态性。22个多态性SSR标记位点中，每位点检测出等位基因2~15个，共检测出等位基因132个，平均每位点6.0 个。各多态位点检测出基因型为2~11种，位点HVM33的基因型最多。各多态位点的多态信息指数为0.16~0.91, 平均为0.65。根据PIC值选择了13个SSR标记用于我国青藏高原栽培青稞基因型鉴定，这些标记的PIC值为0.6以上。结合PIC值和基因型差异，选择了8个多态信息含量高的SSR标记，构建了高效指纹图谱，此图谱能把64份材料完全区分。 贮藏蛋白电泳分析是研究相关编码蛋白基因多态性的非常有效的方法。大麦单体蛋白与小麦醇溶蛋白相对应，具有丰富的多态性，可用于大麦遗传多样性、品种鉴定和群体进化等研究。本研究通过A-PAGE电泳技术研究了84份青藏高原栽培青稞的单体醇溶蛋白多态性。大麦单体醇溶蛋白图谱与小麦醇溶蛋白电泳图谱类似，所分离的蛋白清晰地分为ω－，γ－，β－和α－四个部分。青藏高原栽培青稞单体醇溶蛋白具有丰富的多态性，84份青稞材料中存在43条不同的蛋白带，75种组合带谱；其中67种为单一材料所独有，另8种则分别包含了2-3份材料。每份材料中拥有醇溶蛋白带为6－16条，含有6-10条单体醇溶蛋白带材料较多。西藏和四川材料群体单体醇溶蛋白多态性不同，具有区域特异性。西藏材料中发现了40条不同蛋白带，3条特异带，46 种蛋白组合；四川材料中出现了40种不同蛋白带，26种条带组合, 3条特异带。基于单体蛋白多态性的聚类与材料的来源有一定的相关性。A-PAGE单体蛋白具有丰富的多态性，可作为遗传研究和品种鉴定的标记。 大麦醇溶蛋白（hordein）是大麦籽粒的主要贮藏蛋白，与大麦的营养品质和加工品质密切相关，而且具有丰富的多态性，广泛用于品种鉴定、种质筛选、遗传多样性和亲缘关系研究。B组醇溶蛋白是主要的醇溶蛋白组份，约占总醇溶蛋白的80%，而且具有丰富的多态性。本研究采用SDS-PAGE分析了72份青藏高原栽培青稞B组醇溶蛋白的遗传多样性。青藏高原栽培青稞B组醇溶蛋白具有丰富的多态性，72份青稞材料中存在15种蛋白带，30种组合带谱，其中15种为单一材料所独有，另15种则分别包含了2-10份材料。每份材料中B组醇溶蛋白条带数为4-8条，含5、6条的材料较常见。不同来源的群体材料间B组醇溶蛋白组成存在差异，西藏青稞含有26种蛋白组合带谱，其中有19种特异带谱；四川群体中共发现11种蛋白组合带型，其中有4种特有带谱。两群体中都存在稀有条带。聚类分析将材料分成三组，材料聚类与材料来源地没有明显的相关性。 淀粉粒蛋白（Starch granule proteins, SGPs）是一类与淀粉粒结合的微量蛋白，一些淀粉粒蛋白具有淀粉生化合成中主要的酶蛋白功能，其变异会影响淀粉含量和特性，从而影响淀粉的应用。关于我国大麦淀粉粒组成研究还未见报道。本实验首次开创了我国大麦淀粉粒结合蛋白的研究工作。采用SDS-PAGE电泳技术研究了青藏高原栽培青稞的SGP组成，并分析了不同SGP组合间淀粉含量的差异，初步探索了所分离的SGP蛋白与淀粉合成的关系。66份青稞材料中分离了10种主要的SGP，其表观分子量为40-100KD，低于60KD的SGP带有7条，共有16种组合带谱；各SGP蛋白和组合带谱出现的频率存在差异，青藏高原青稞的SGP组成存在多态性。西藏青稞和四川青稞的SGP组成有很大差异，SGP组成具有地域差异性，西藏青稞含有12种蛋白组合带谱，其中有9种特异带谱；四川群体中共发现7种蛋白组合带型，其中有4种特有带谱；两群体中仅有3种共同的蛋白组合带谱。SGP蛋白特性将66份青稞分为三组, 即Ⅰ、Ⅱ、Ⅲ，材料聚类与材料来源具有一定的相关性。不同组合带谱材料间淀粉含量差异显著性检验结果显示，不同带谱间材料的总淀粉含量、直链淀粉含量和支链淀粉含量有差异，带谱2（SGP1+3+7+9+10）和8（SGP1+2+4+6+8）的总淀粉含量及支链淀粉含量显著大于组合带谱3（SGP1+3+7+10）的总淀粉含量。组合带谱7（SGP1+2+6+8）的直链淀粉含量显著低于带谱11（SGP1+5+8）的直链淀粉。带谱SGP2、3、4、5、6、7、8、9、10可能参与淀粉合成，SGP9可能与高支链淀粉的合成相关。 SSR标记位点、单体醇溶蛋白、B组醇溶蛋白、淀粉结合蛋白等四个方面的研究结果表明青藏高原SSR标记多态性、单体醇溶蛋白多态性、B组醇溶蛋白多态性和SGP多态性都非常丰富，与青藏高原是栽培青稞的多样性分布中心的观点一致。 青藏高原栽培青稞的SSR标记、单体醇溶蛋白、B组醇溶蛋白和SGP多态性表现出很大差异。SSR标记覆盖了整个基因组，多态性非常高。单体蛋白、B组醇溶蛋白、SGP蛋白是育种中非常关注的性状，他们只是代表基因组中的某一区域或位点，多态性相对较低。但单体蛋白多态性很高，84份材料中检测出43条不同蛋白带，75种不同的组合带谱。SSR标记技术和单体蛋白技术都是遗传多样性研究的有力工具，但单体蛋白技术不仅多态性高，而且经济、操作简便，是种质鉴定的理想方法。 对不同标记的多态性材料数据进行聚类，聚类图能为我们提供各材料间的遗传相似信息，为材料选择提供参考。但材料聚类与材料来源的地理区域的相关性表现不一致。SSR聚类和B组醇溶蛋白聚类与材料的来源地无相关性，而单体醇溶蛋白和SGP聚类与材料来源地有一定相关性，即西藏群体和四川群体分别有集中类群，这可能是人为选择的附加效应。 不同来源的群体材料的遗传多样性不同，具有区域特异稀有基因，加强不同地区间资源的交换和配合使用，有利于增加群体遗传多样性和新品种培育。 青藏高原栽培青稞的麦芽浸提性状、淀粉性状、病虫及裸粒等重要农艺性状控制位点存在丰富的变异，遗传基础宽广，可能蕴藏着多种不同的等位基因，是研究重要性状遗传特性、基因资源挖掘和遗传育种的宝贵资源库。 Hulless barley, due to its favorable attributes such as high feed value, good human nutrition，rich dietary fiber and ease processing, attracts people,s attention . Hulless barley plays a very important role in Tibetan life, used as essential food crop, main animal feed and important fuel. In addition to tsampa (roasted barley flour), a main food for Tibetan, hulless barley is also made into cake, soup, porridge, recent naked barley liquor and cornmeal. Qinghai-Tibet Plateau is one of a few areas which plant naked barley widely in the world and also has a long growing history. Genetic diversity of the cultivated hulless barley in this region , however, has not been documented. The study of genetic diversity existing within this population is of particular interest in germplasm identification, preservation, and new cultivar development. This study analyzed the genetic diversity of the cultivated naked barley from Qinghai-Tibet plateau through the study of SSR marker loci and monomeric prolamins, B-horden and starch granule proteins. SSRs are present abundantly in genomes of higher organisms and have become a popular marker system in plant studies. SSRs offer a number of advantages, such as the high level of polymorphisms, locus specificity, co-dominance, reproducibility, ease of use through PCRand random distribution throughout the genome. In barley, several hundred SSRs have been developed and genetically mapped and can therefore be selected from specific genomic regions. The genetic diversity of 64 cultivated naked barley from Tibet and Sichuan was studied with 30 SSRs of known map location.Among the selected SSR markers, PCR products of 5 SSR markers were not obtained and 3 SSR marker loci were monomeric. A total of 132 alleles were identified at 22 polyomeric SSR loci. The number of alleles per locus ranged from 2 to 15, with an average of 6.0. The polymorphism information content values for the SSRs ranged from 0.08 to 0.94, with an average of 0.65. 13 SSR markers with the PIC value >0.6 have been selected for discrimination of Qinghai-Tibet naked barley genotypews. A finger Print map was developed through 7 SSR markers with the high PIC value. It could be used as an efficient tool for gene discovery and identification of gernplasm. Hordeins, the main storage proteins of the barley seed, are composed of momomeric and polymeric prolamins and divided into -A, B, C and D groups in order of decreasing electrophoretic mobility. Hordeins show high inter-genotypic variation and have been extensively used as markers for cultivar identification and analyzing the genetic diversity. This study analyzed the genetic diversity of B-hordein in 72 naked barley from Qinqhai-Tibet Plateau. Extensive diversity was observed. A total of 15 different bands and 30 distinct patterns were found. Jaccard's coefficient of similarity was calculated, and the accessions were divided into three　main groups by cluster analysis using UPGMA. Differentiation among the populations from different collecting regions based on the polymorphism of B-hordein was investigated. Monomeric prolamins show high inter-genotypic variation and have been used as molecular markers for cultivar identification, analyzing the genetic diversity in collections and investigating the evolution processes and structure of populations However, the cultivated hulless accessions from Qinghai-Tibet Pateau in China have never been examined with respect to monomeric prolamins. This study analyzed the genetic diversity of monomeric prolamins (protein fraction corresponding to wheat gliadins) using the Acid -PAGE technique in eighty-four cultivated hulless barley from Qinqhai-Tibet Plateau in China. Extensive diversity was observed. A total of 43 different bands were found, of which 21 different bands were in the region of ω group, 8 in the region of γ, 8 in the region of β, and 6 in the region of α group. Among the 86 accessions, 75 distinct patterns were identified. The number of bands ranged from 6 to 16, depending on the variety. Jaccard’s coefficient of similarity was calculated, and the lines were grouped by cluster analysis using UPGMA. A dendrogram was obtained from the analysis of the groups and five main clusters were identified. No relationship between the distribution in the dendrogram and growth habits and origins of the cultivars could be detected. Starch is the major constituent of the cereal endosperm, comprising approximately 65% of the dry weight of the mature wheat grain. The starch formed in all organs of plants is packaged into starch granules, which vary widely between species and cultivars in size and shape. Wheat endosperm starch granules contain about corresponding to the main biosynthase of starch. This report firstly dealed with intraspecific variation of the major SGPs in cultivated naked barley from Qinghai-Tibet plateau. A total of 10 major SGPs were observed in the range of 40KD-100KD and 16 types of patterns were found. Based on the variation of SGPs, accessions studied were classified into 3 groups. A geographical cline of electrophoregram was observed. In addition, significance test of the difference of starch content among groups and types of patterns were done, and the results indicated those SGPs could be related to the content of starch. Diagram obtained through cluster analysis exhibited a structuration of diversity and genetic relationship among cultivated hulless accessions. In breeding program, parents with genetically distant relationship for hybridization will increase genetic diversity of progenies. In conclusion, cultivated naked barley from Qinghai-Tibet Plateau in China presents a high variability with respect to monomeric prolamins，SSR markers , B- hordeins and SGPs. The result of this study supports Qinghai-Tibet Plateau is the center of cultivated hulless barley and the cultivated naked barley is considered to be a gene pool with large diversity and could be applied to breeding for cereal.

论自然保护与资源开发的策略

The conservation of species requires preservation of natural habitats,where the integrity of natural habitats has been severely disturbed and species goes extinct. All natural habitats are continuing to decline both inside and outside of reserves. Habitat change is partly a natural process (e.g., succession), but human activities have accelerated the process so that natural rate of renewal is insufficient to maintain natural habitats. This paper provided concept, methods of habitat renewal, habitat mitigation and their implication to protection and exploitation of natural resource. We argue that our only resourse, in light of these scenarios, is to adopt a new conservation strategy that considers the importance of habitat renewal and habitat mitigation in addition to habitat preservation. Accordingly, in our management decision, we must not only choose the size of area to preserve ,but also the size of area to balance habitat loss with habitat renewal or habitat mitigation. Finally, we explored the application of habitat renewal and habitat mitigation in regional sustainable development of Liaohe Delta wetland.

基于语义的Web服务匹配及其框架模型研究

随着Internet上异构应用系统的大量增加和SOA技术的空前发展，Web服务技术变得越来越重要，已经成为了学术界和工业界关注的热点。在Web服务技术中，服务发现为Web服务消费者调用Web服务提供者提供的服务提供了桥梁，起到非常重要的承接作用，成为了Web服务技术中的重点。目前的Web服务发现机制主要有两种，第一种是传统的Web服务发现方式，主要基于UDDI（Universal Description， Discovery and Integration）的纯粹关键字查找；第二种是基于Web服务的语义信息，进行Web服务间的语义匹配。 第一种方法的基础UDDI是国际标准，而且应用也最为广泛，但UDDI中对于Web服务的描述是基于语法的，而且缺乏Web服务所特有的I/O属性和服务质量属性等信息。第二种方法基于Web服务的语义信息，包括Web服务所特有的I/O属性，但因为缺乏灵活有效的Web服务匹配方法和与之对应的Web服务匹配框架，限制了其应用。 基于此，本文在对当前语义Web服务匹配技术分析和研究的基础上，对当前的语义Web服务匹配方法进行了改进，同时提出了基于过滤器（filter）的语义Web服务匹配框架模型。本文的主要工作有： 1）对目前的语义Web服务匹配技术进行了较为全面深入的探讨和综述。 2）对当前的语义Web服务匹配的各个阶段进行了详细的分析，对其中的匹配方法进行了改进。提出了基于向量空间模型(VSM)和TF-IDF(Term Frequency–Inverse Document Frequency)思想的本体权重的计算方法，本体层次关系图中边的权重的计算方法和本体之间相似度的计算方法。 3）提出了基于web服务黑盒属性的语义。 4）语义Web服务匹配框架方面，本文提出了基于filter的语义Web服务匹配框架，并将其延伸到非语义Web服务系统中。

Development of expressed sequence tags from the bay scallop, Argopecten irradians irradians

The bay scallop, Argopecten irradians irradians, introduced from North America, has become one of the most important aquaculture species in China. Inan effort to identify scallop genes involved in host defense, a high-quality cDNA library was constructed from whole body tissues of the bay scallop. A total of 5828 successful sequencing reactions yielded 4995 expressed sequence tags (ESTs) longer than 100 bp. Cluster and assembly analyses of the ESTs identified 637 contigs (consisting of 2853 sequences) and 2142 singletons, totaling 2779 unique sequences. Basic Local Alignment Search Tool (BLAST) analysis showed that the majority (73%) of the unique sequences had no significant homology (E-value >= 0.005) to sequences in GenBank. Among the 748 sequences with significant GenBank matches, 160 (21.4%) were for genes related to metabolism, 131 (17.5%) for cell/organism defense, 124 (16.6%) for gene/protein expression, 83 (11.1%) for cell structure/motility, 70 (9.4%) for cell signaling/communication, 17 (2.3%) for cell division, and 163 (21.8%) matched to genes of unknown functions. The list of host-defense genes included many genes with known and important roles in innate defense such as lectins, defensins, proteases, protease inhibitors, heat shock proteins, antioxidants, and Toll-like receptors. The study provides a significant number of ESTs for gene discovery and candidate genes for studying host defense in scallops and other molluscs.

Application of forecasting structural cracks technique of 3D move in Chengdao buried hill

3DMove software, based on the three-dimension structural model of geologic interpretation, can forecast reservoir cracks from the point of view of formation of the structural geology, and analyze the characteristics of the cracks. 3DMove software dominates in forecasting cracks. We forecast the developments and directions of the cracks in Chengbei buried hill with the application of forecasting technique in 3DMove software, and obtain the chart about strain distributing on top in buried hill and the chart about relative density and orientation and the chart about the analysis of crack unsealing. In Chengbei 30 buried hill zone, north-west and north-east and approximately east-west cracks in Cenozoic are very rich and the main directions in every fault block are different. Forecasting results that are also verified by those of drilling approximately accord with the data from well logging, the case of which shows that the technique has the better ability in forecasting cracks, and takes more effects on exploration and exploitation of crack reservoir beds in ancient buried hill reservoirs.

Winter counter-wind currents off the southeastern China coast: A review

This review covers the discovery and studies of the year-round northeastward currents off the southeastern China coast, paying special attention to its upwind characteristic in winter, mainly focusing on work by Chinese oceanographers. This current system is a prominent and unique phenomenon in the shelf circulation of the world ocean. The general features of the current system are summarized. The evidence for the existence and the variation of the three parts of the currents-the South China Sea Warm Current, the Taiwan Strait Warm Current and the Taiwan Warm Current-are separately elucidated. The formation mechanisms of the current as a whole are explained using dynamic analysis and numerical simulation results. Some suggestions for further studies are also made.

First record of the family Spengeliidae (Hemichordata : Enteropneusta) from Chinese waters, with description of a new species

Six species belonging to two families of Hemichordata have previously been recorded in Chinese waters. This paper records the discovery and description of a new species of the genus Glandiceps found in Jiaozhou Bay, Qingdao, Shandong Province, named Glandiceps qingdaoensis. The new species has a long proboscis with dorsal and ventral grooves, a stomochord with a long vermiform process, a proboscis cavity with a dorsal median, right and left glomeruli, right and left glomeruli very large and encircling the stomochord, a proboscis skeleton in the cavity extends into the median posterior of the collar, a well-developed dorsal ventral muscular septum in the proboscis cavity dividing the cavity completely into two separate parts. The collar cord is without giant nerve roots. The trunk with four distinct regions that can be recognized externally: branchial-genital region, genital region, hepatic region, and intestinal region. The dorsal pharynx is large and the gill pores are small. The tongue bars are encircled by vesicles, and the first gonad commences at the level of the second or third gill slit.
