Sedimentology and Diagenesis of Upper Triassic Sandstones, with Emphasis on the Snadd-Fruholmen Transition, Barents Sea

Triassic and Jurassic sediments from two cores in the Nordkapp Basin, Barents Sea, were analyzed by sedimentological, petrographic, SEM and XRD methods. The objective of the study was to gain better understanding of the depositional environments of the Upper Triassic-Jurassic, Snadd-, Fruholmen- and Stø formations with emphasis a mineralogical shift in the transition between the Snadd and Fruholmen formations, and try to relate the differences to depositional environment, climatic changes and diagenesis.The studied sediments of the Snadd and Fruholmen formations represent a transition from tidal flat, shoreline and inner shelf deposits. And the Stø Formation mainly represents inner shelf deposits, with exception of some fluvial deposits due to a local variation in one of the cores. The deposits represent an overall transgressive trend.The diagenetic processes differ in the three formations due to dissimilar depositional environment. In the Snadd Formation rhizocretions have been observed in combination with rootlets,and high levels of iron and manganese indicate influence by fresh-water. XRD analyses of mudstones showed no great compositional differences the Snadd and Fruholmen formations supporting observations from sandstone compositions of similar provenance and environment above and below the formation boundary.The largest compositional variation is seen between the Fruholmen and Stø formations, this is in accordance with other studies conducted in the Nordkapp Basin. The distinct increase in maturity may be due to extensive reworking connected with a regional transgression and sea-level rise

Treballs Finals de Grau de Matemàtiques, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2023, Director: Josep Vives i Santa Eulàlia[en] The aim of this work is to examine spatial statistics fundamentals and to study three different types of models used for flux migration forecasting: gravity models, radiation models and deep gravity models. The attention is drawn on Gaussian random fields, stationarity, kriging, Gaussian autoregression models and Markov random fields. Four gravity models, their respective four multi-linear regression models and a radiation model are implemented, all pulling the same data, to forecast migration flows within Catalonia (Spain) in 2019 between comarques by using data from these locations

Brace for Impact: The Effects of Victim Impact Evidence and Judicial Instructions on Juror Memory Distortion and Sentencing Decisions in Capital Trials

The utilization of visual evidence in the courtroom has increased exponentially in an effort to portray additional information that cannot otherwise be established via forensic evidence and expert testimony. According to Rule 403 of the Federal Rules of Evidence (1984), visual evidence may be permitted in court if the prejudicial value does not significantly outweigh the probative value. The admissibility of visual evidence however, becomes controversial when combined with victim impact statements (VIS) during the penalty phase of capital trials. Previous research has indicated that jurors are often unable to perceive emotional testimony and subsequently make objective sentencing decisions that are based on reason rather than emotion. Moreover, previous literature has demonstrated that emotionally charged visual evidence can significantly distort jurors’ memories of case facts depending on their desire for retribution. Despite these findings, previous literature has not empirically explored the combined effects of emotional testimony and visual evidence on juror memory distortion and sentencing decisions.The present study examined the combined effects of VIS and photographic evidence on juror memory distortion and sentencing decisions. Participants will be randomly assigned to three conditions and instructed to read identical murder trial transcripts and VIS during the penalty phase of a capital case. Participants were exposed to varying levels of emotionally charged photographs and instructed to subsequently sentence the defendant to either life in prison or to death. Participants’ memory recall and emotional states were evaluated. Implications are discussed

Preferential Paths of Air-water Two-phase Flow in Porous Structures with Special Consideration of Channel Thickness Effects.

Accurate understanding and predicting the flow paths of immiscible two-phase flow in rocky porous structures are of critical importance for the evaluation of oil or gas recovery and prediction of rock slides caused by gas-liquid flow. A 2D phase field model was established for compressible air-water two-phase flow in heterogenous porous structures. The dynamic characteristics of air-water two-phase interface and preferential paths in porous structures were simulated. The factors affecting the path selection of two-phase flow in porous structures were analyzed. Transparent physical models of complex porous structures were prepared using 3D printing technology. Tracer dye was used to visually observe the flow characteristics and path selection in air-water two-phase displacement experiments. The experimental observations agree with the numerical results used to validate the accuracy of phase field model. The effects of channel thickness on the air-water two-phase flow behavior and paths in porous structures were also analyzed. The results indicate that thick channels can induce secondary air flow paths due to the increase in flow resistance; consequently, the flow distribution is different from that in narrow channels. This study provides a new reference for quantitatively analyzing multi-phase flow and predicting the preferential paths of immiscible fluids in porous structures

Brukermedvirkning innen barnevernet

Problemstilling: Hvordan kan vernepleieren fremme brukermedvirkning til barn under barnevernets omsorg? Introduksjon: Brukermedvirkning for barn er et komplekst tema. Lovverket er veldig tydelig på hva som er barnets rettigheter. Nyere forskning peker imidlertid på at dette ikke blir fulgt. Vernepleiere som jobber innen barnevernet har et faglig krav om å ivareta brukermedvirkning. Skreddersydd tilnærming er nøkkelen for fremming av brukermedvirkning, og med det fungere som en støtte for et sårbart barn. Dette lar seg ikke gjøre uten relasjonsbygging, noe som er en del av vernepleierens kjernekompetanse. Hensikt: Hensikten med denne studien er å finne ut hvilke roller og kvaliteter vernepleieren bør inneha for å fremme brukermedvirkningen til barn under barnevernets omsorg. Metode: Denne bacheloroppgaven er en litteraturstudie. Den bygger på analysen av fem fagfellevurderte forskningsartikler, samt relevant teori for å svare på problemstillingen. Resultat: Studien identifiserer særlig fire temaer som påvirker barns brukermedvirkning. Disse er relasjon, maktubalanse, holdninger og organisatoriske rammer. En vernepleier kan ved bruk av sin faglige kunnskap og kompetanse gjennom partner- eller pådriverrollen bryte ned utfordringene, og med det fremme brukermedvirkningen til barn. Konklusjon: Vernepleieren kan fremme brukermedvirkningen hos barn under barnevernets omsorg ved å etablere sterke relasjoner, utjevne maktforholdet, vise til gode holdninger samt å utfordre de organisatoriske rammene vernepleieren jobber under.

Introduction: User involvement regarding children is a complex topic. The legislation is very clear about the children's rights. However, it appears from recent research that these rights are not followed. Social educators who work in the Child Welfare Service have a professional requirement to ensure user participation. A tailored approach is key to promote user participation as well as being a support to a vulnerable child. This cannot be done without fostering the relationship to the child, which is one of the social educator's core competencies. Purpose: The purpose of this study is to identify the roles and qualities the social educator should possess in order to promote user involvement from children that are under the care of the Child Welfare Service. Method: This bachelor' thesis is a literature review. It is based on the analysis of five peer-reviewed research articles, as well as other theories that is relevant to the topic. Result: Four themes that affect children's user participation emerged. These include relationships, power imbalances, attitudes and organizational frameworks. A social educator can, by using his or her professional knowledge and expertise, break down the barriers and thereby promote user participation of children. Conclusion: The social educator can promote user participation for children under the care of the Child Welfare Service by establishing strong relationships, balance power dynamics, demonstrate good attitudes and challenge the organizational framework under which the social educator works. Keywords: social educator, promote, user participation, participation, child welfare service, chil

Evaluation of the biodegradability of hazardous industrial solid waste: Study of key parameters

The biological stability of solid waste is one of the main problems related to the environmental impact of landfills and their long-term emission potential. Current European legislation (European Landfill Directive, EC/99/31) introduced the need to reduce biodegradable organic compounds deposited in landfills; however, it set neither official parameters nor methods to define the stability of such a waste. In Spain, biodegradability is generally evaluated using the biological oxygen demand/chemical oxygen demand (BOD5/COD) ratio, measuring it on the leachate, thus not considering the non-soluble fraction and therefore creating false negatives. To solve this problem, the biodegradability of hazardous industrial waste has been determined by measuring its respirometric activity (AT4). Our results show that the measure of the AT4 is independent of the enrichment with a microbial inoculum, and a sample size no higher than 20 g could be a reasonable value for a sensitive biodegradability determination. The highest respirometric index is obtained in waste with pH values between 6.5 and 10.5. Furthermore, respirometric biodegradability values are independent of traditional parameters of organic matter characterization such as BOD5/COD ratio, volatile content, and total and dissolved organic carbon. Consequently, the AT4 parameter provides new information on the composition and stability of organic matter in hazardous industrial waste. Its incorporation into pre-disposal waste characterization protocols allows to identify waste that exceeds recommended biodegradability thresholds. This approach ensures that only waste meeting specified biodegradability standards is deposited, avoiding landfill emissions and related environmental impacts, and thereby improving the overall effectiveness and sustainability of waste management practices.info:eu-repo/semantics/publishedVersio

Continuum-based models and concepts for the transport of nanoparticles in saturated porous media: A state-of-the-science review

Environmental applications of nanoparticles (NP) increasingly result in widespread NP distribution within porous media where they are subject to various concurrent transport mechanisms including irreversible deposition, attachment/detachment (equilibrium or kinetic), agglomeration, physical straining, site-blocking, ripening, and size exclusion. Fundamental research in NP transport is typically conducted at small scale, and theoretical mechanistic modeling of particle transport in porous media faces challenges when considering the simultaneous effects of transport mechanisms. Continuum modeling approaches, in contrast, are scalable across various scales ranging from column experiments to aquifer. They have also been able to successfully describe the simultaneous occurrence of various transport mechanisms of NP in porous media such as blocking/straining or agglomeration/deposition/detachment. However, the diversity of model equations developed by different authors and the lack of effective approaches for their validation present obstacles to the successful robust application of these models for describing or predicting NP transport phenomena. This review aims to describe consistently all the important NP transport mechanisms along with their representative mathematical continuum models as found in the current scientific literature. Detailed characterizations of each transport phenomenon in regards to their manifestation in the column experiment outcomes, i.e., breakthrough curve (BTC) and residual concentration profile (RCP), are presented to facilitate future interpretations of BTCs and RCPs. The review highlights two NP transport mechanisms, agglomeration and size exclusion, which are potentially of great importance in controlling the fate and transport of NP in the subsurface media yet have been widely neglected in many existing modeling studies. A critical limitation of the continuum modeling approach is the number of parameters used upon application to larger scales and when a series of transport mechanisms are involved. We investigate the use of simplifying assumptions, such as the equilibrium assumption, in modeling the attachment/detachment mechanisms within a continuum modelling framework. While acknowledging criticisms about the use of this assumption for NP deposition on a mechanistic (process) basis, we found that its use as a description of dynamic deposition behavior in a continuum model yields broadly similar results to those arising from a kinetic model. Furthermore, we show that in two dimensional (2-D) continuum models the modeling efficiency based on the Akaike information criterion (AIC) is enhanced for equilibrium vs kinetic with no significant reduction in model performance. This is because fewer parameters are needed for the equilibrium model compared to the kinetic model. Two major transport regimes are identified in the transport of NP within porous media. The first regime is characterized by higher particle-surface attachment affinity than particle-particle attachment affinity, and operative transport mechanisms of physicochemical filtration, blocking, and physical retention. The second regime is characterized by the domination of particle-particle attachment tendency over particle-surface affinity. In this regime although physicochemical filtration as well as straining may still be operative, ripening is predominant together with agglomeration and further subsequent retention. In both regimes careful assessment of NP fate and transport is necessary since certain combinations of concurrent transport phenomena leading to large migration distances are possible in either case
