Complexities associated with dissolved organic matter (DOM) isolation from seawater have hampered compositional characterization of this key component of global carbon and nutrient cycles. Two techniques, Electrodialysis (ED) and Solid Phase Extraction (SPE), were combined to more effectively isolate DOM from salt-containing waters. Sample recovery was optimized and evaluated on a range of samples including coastal ocean seawater, open ocean seawater, artificial seawater from cultures of marine phytoplankton, and artificial seawater samples containing standard compounds of different molecular sizes and charge. ED was performed with a system optimized for processing 2 to 10 L sample volumes and SPE was performed using Bond Elut PPL exchange resin. With the combination of ED and PPL techniques an average recovery of 76.7 ± 2.6% was obtained for natural coastal seawater. Comparison of C/N ratios and fluorescence excitation emission matrices (EEMs) taken at the beginning and end of the recovery process indicated that the final recovered material was representative of the DOM present in the original samples.

Natten mellan den 27:e och 28:e april 1889 mördas HannaJohansdotter på den skånska landsbygden i Yngsjö. Hon tas avdaga av sin man, Per Nilsson, och sin svärmor, Anna Månsdotter.Under rättegången i Villands häradsrätt utvecklas händelsentill en utredning som varade i drygt nio månaders tid där debåda anklagade gjort sig skyldiga till mycket mer än bara mord.Den här undersökningens syfte är att genom en hermeneutisktextanalys utröna vilka de anklagade, Anna Månsdotter och PerNilsson, var som personer med utgångspunkt i Villandshäradsrätts rättegångsprotokoll. Uppsatsen tar avstamp i AnjaPetersens teori kring rättsväsendets framställningar av enmanlig och kvinnlig våldsbrottsling där den manligebrottslingen som aggressiv och våldsam till sin natur och denkvinnlige brottslingen som ett offer för sina omständigheter.I fallet med Yngsjömordet visar det sig att båda dessakaraktäriseringar ger sig uttryck under rättegången. Dock ärtillämpningen av dessa karaktärsdrag applicerade på motsattkön. Per Nilsson blir, enligt Petersens teori, den kvinnligebrottslingen och Anna Månsdotter blir den manlige.

The eXtensible Access Control Markup Language (XACML) is allowing enterprises to implement a standard way of access control to their resources. Security administrators no longer need to duplicate their efforts in writing multiple policies for different resources since a XACML policy can be applied to multiple resources. Companies such as IBM, Sun Microsystems, Oracle, and Cisco are already providing integration of XACML in their products. Although the introduction of XACML has provided enterprises with a better approach of commonly realizing access control, there are still inconsistencies that policy administrators need to be aware of. This thesis identifies some of the inconsistencies in XACML today and introduces a new tool that can be used to visualize some of those inconsistencies. This new tool could be used by a policy administrator to visualize possible conflicting data among a set of policies.

"We analyze data on body mass index (BMI) in the third National Health and Nutrition Examination survey, predict finite population BMI stratified by different domains of race, sex and family income, and investigate what adjustment needed for nonresponse mechanism. We built two types of models to analyze the data. In the ignorable nonresponse models, each model is within the hierarchical Bayesian framework. For Model 1, BMI is only related to age. For Model 2, the linear regression is height on weight, and weight on age. The parameters, nonresponse and the nonsampled BMI values are generated from each model. We mainly use the composition method to obtain samples for Model 1, and Gibbs sampler to generate samples for Model 2. We also built two nonignorable nonresponse models corresponding to the ignorable nonresponse models. Our nonignorable nonresponse models have one important feature: the response indicators are not related to BMI and neither weight nor height, but we use the same parameters corresponding to the ignorable nonresponse models. We use sample important resampling (SIR) algorithm to generate parameters and nonresponse, nonsample values. Our results show that the ignorable nonresponse Model 2 (modeling height and weight) is more reliable than Model 1 (modeling BMI), since the predicted finite population mean BMI of Model 1 changes very little with age. The predicted finite population mean of BMI is affected by different domain of race, sex and family income. Our results also show that the nonignorable nonresponse models infer smaller standard deviation of regression coefficients and population BMI than in the ignorable nonresponse models. It is due to the fact that we are incorporating information from the response indicators, and there are no additional parameters. Therefore, the nonignorable nonresponse models allow wider inference."

O Granito Três Figueiras representa a única ocorrência de granitos peraluminosos no extremo sudeste do Cinturão Dom Feliciano (RS), sendo um granitoide sincinemático à Zona de Cisalhamento Arroio Grande. O objetivo deste trabalho é a caracterizaração geológica do granito, através de estudos de campo, microscopia óptica, geoquímica de rocha total (ICP-MS) e datações U-Pb em zircão (SHRIMP). O granito é cinza claro, composto por quartzo, K-feldspato, plagioclásio, muscovita, biotita (M‟ 7-10), com granada, turmalina, zircão, monazita e apatita como minerais acessórios. Nas porções afetadas pela zona de cisalhamento, desenvolve uma trama milonítica com foliação tectônica subvertical com mergulho > 70° para SE e lineação de estiramento sub-horizontal marcada pelas micas e agregados estirados de quartzo e feldspato, com direção N80°E e caimento de até 10° para ENE, que demonstram o caráter transcorrente desta zona. Nos termos milonitizados, o arranjo da matriz chega a apresentar textura granoblástica poligonal, recristalização parcial de dos cristais de feldspatos e a formação de mirmequitos por deformação, o que indicam temperaturas de deformação de pelo menos 550°C. Indicadores cinemáticos como feldspatos com cauda de recristalização assimétricas, pares S-C, atestam uma cinemática destral para essa zona. O granito é classificado como peraluminoso, com teores de A/CNK entre 1,07 e 1,21 e coríndon normativo entre 1,2 a 3 %. Possui altos teores de SiO2, Al2O3, álcalis, e baixos teores de FeO, MgO e TiO2. Apresenta correlação negativa para a maioria dos elementos maiores, o que indica que o principal processo de evolução magmática foi a cristalização fracionada. Uma fonte homogênea é sugerida a partir da relação entre elementos traços e ETR. Com a datação U-Pb se obteve uma idade de cristalização magmática de 585 ± 16 Ma, que registra um importante eventode fusão crustal para o extremo sudeste do Cinturão Dom Feliciano. / The TrêsFigueiras Granite represents the occurrence of peraluminous granite in the southeastern Dom Feliciano Belt, representing a sinkynematic rock to the Arroio Grande Shear Zone. The aim of this work is to make the geologic characterization of the granite through field studies, optic microscopy, geochemistry and U-Pb geochronology. The granite is light grey coloured composed by quartz, K-feldspar, plagioclase, muscovite, biotite (M‟ 7-10), with garnet, tourmaline, zircon, monazite and apatite as accessory minerals. When affetected by shear zone, it develops a mylonitic fabric with subvertical tectonic foliation with dip >70° for SE and a stretching lineation marked by elongated micas and aggregates of quartz and feldspar, both with a N80°E trend dipping 10° ENE. On the milonitc terms the matrix shows granoblasticpolygonal texture, parcialrecristalization of feldspar and formation of mirmequite by deformation which indicates deformation temperatures of at least 550°C. Kynematic indicators like assimetric tails in feldspar and S-C pair define a dextral kinematic to this zone. The granite is classified as a peraluminous granite with A/CNK content ranging between 1.07 and 1.21 and normative corundum from 1.2 to 3 %. It has high SiO2, Al2O3 and alkalis (K2O + NaO) and low FeO, MgO and TiO2 contents. In Harker diagrams shows negative correlation for most of the major elements in response to the fractional crystallization process. An homogeneous source is suggested based on the relation between trace elements and ETR. Zircon U-Pb SHRIMP dating yielded an age of 585 ± 16 Ma, interpreted as magmatic crystallization an important record of Neoproterozoic peraluminous magmatism in the southeastern portion of the Eastern Domain of Dom Feliciano Belt.

Currently there are several interfaces for XML data, such as DOM, SAX, JAXP, StaX, .NET XML support etc. However, each of them has its advantages and disadvantages. This work analyses the existing XML APIs and identifies their pros and cons from various points of view. On the basis of the results a new DOM API for large XML data is proposed and is provided its prototype implementation. New API uses splitting method for input XML document to smaller ones and querying performs on these smaller XML documents. Finally, using a set of experiments the newly proposed API is compared with the existing ones.

Syftet med den här uppsatsen är att undersöka hur väl svenska och finlandssvenska niondeklassare hanterar utvalda svenska skrivregler och det svenska skriftspråket. Vidare undersöks huruvida det finns olikheter länderna emellan, samt mellan kön. Undersökta språkdrag är fyra till antalet: förekomst av särskrivning, hantering av gemener och versaler, inslag av engelska respektive finska samt hantering av pronomina de, dem och dom. Undersökningsmaterialet består av 100 diskursiva elevtexter från Sverige och Finland, jämnt fördelade mellan länderna. Texterna kommer från nationella prov i ämnet svenska (Sverige) respektive modersmål och litteratur (Finland) genomförda våren 2010 av elever i årskurs 9. En kvantitativ forskningsmetod är tillämpad i denna studie; samtidigt är undersökningen även en kvantitativ jämförelse länderna emellan. Resultatet visar att eleverna i stort hanterar undersökta svenska skriftspråksnormer. Det råder dock tveksamheter gällande hur ord skrivs samman på ett korrekt sätt och när ord stavas med stor respektive liten begynnelsebokstav. Främmande ord och uttryck förekommer inte i någon större utsträckning i de undersökta diskursiva texterna. En viss tveksamhet råder även gällande bruket av personliga pronomen i tredje person plural då somliga elever blandar tal- och skriftspråksformer i sina texter samt överanvänder objektsformen. Vid en jämförelse av variabeln kön visar det sig att pojkarna i min studie har fler felaktigheter i sina texter än vad flickorna har. Överlag behärskar de finlandssvenska eleverna undersökta språkdrag med större säkerhet än de svenska eleverna.
