The effects of Milou central fetal monitoring system on maternal and perinatal outcomes at Landspítali: Retrospective cohort study
No full textBakgrunnur: Ljósmæður hafa í áraraðir sinnt því hlutverki að fylgjast með líðan móður og barns í fæðingu og tryggja sem besta fæðingarútkomu. Ein aðferð til að meta líðan barns í fæðingu er með síritun fósturhjartsláttar. Í ört vaxandi tækniheimi hafa margar sjúkrastofnanir tekið upp síritunarkerfi sem kallast miðlæg fósturhjartsláttarkerfi. Á fæðingarvakt Landspítalans var í október árið 2017 tekið upp slíkt kerfi sem ber heitið Milou. Tilgangur þess var að auka öryggi skjólstæðinga þar sem fleira starfsfólk sér nú fósturhjartsláttarritin í rauntíma en áður, jafnframt því að bæta skráningu og varðveislu gagna.
Tilgangur: Kanna tengsl Milou miðlægs fósturhjartsláttarkerfis við útkomu fæðinga á fæðingarvakt Landspítala m.t.t tíðni áhaldafæðinga, bráðakeisaraskurða og útkomu nýbura eftir fæðingu.
Aðferðir: Rannsóknin er afturvirk ferilrannsókn. Gögnin voru fengin úr fæðingarskrá og eru rannsóknartímabilin tvö. Fyrra tímabilið var árið fyrir innleiðingu Milou, frá 1. október 2016 til og með 30. september 2017. Seinna tímabilið var eftir innleiðingu Milou, frá 1. október 2018 til og með 30. september 2019. Þátttakendur í rannsókninni voru alls 4279 eða allar konur sem fengu greininguna síritun fósturhjartsláttar í fæðingu og fæddu einbura í höfuðstöðu eftir 37. vikna meðgöngu á Landspítala. Gerð var lýsandi tölfræði til að lýsa bakgrunns- og útkomubreytum. Einnig var gerð greinandi tölfræði þar sem framkvæmd voru bæði kí-kvaðrat og t-próf til að meta mun á milli rannsóknarhópa.
Niðurstöður: Ekki reyndist marktæk aukning á áhaldafæðingum og bráðakeisaraskurðum fyrir og eftir innleiðingu á Milou á fæðingarvakt Landspítala. Auk þess reyndist ekki marktækur munur á fjölda nýbura með Apgar stigun <7 við 5 mínútur.
Ályktanir: Innleiðing á miðlæga fósturhjartsláttarkerfinu Milou á fæðingarvakt Landspítalans tengist hvorki fjölgun á inngripum né bættri útkomu nýbura. Nauðsynlegt er að vera áfram vakandi fyrir áhrifum Milou á útkomu fæðinga á Landspítala og er frekari rannsókna þörf á efninu.

One method is by monitoring the fetal heart rate. In this era of rapid technological change, many medical facilities have adopted systems known as central fetal monitoring systems. In October 2017, one such system, called Milou, was installed at Landspítali‘s birth unit. The intention was twofold: to increase the safety of clients, as more staff would be in a situation to see the heart rate charts in real time than before, and to improve documentation.
Aim: The aim of this study was to explore the relationship between Milou central fetal monitoring system and the outcome of births at Landspítali‘s birth unit in terms of the rate of operative deliveries, emergency c-sections, and the outcome of newborns after birth.
Methods: The study is a retrospective cohort study. The data was obtained from birth records and covers two periods. The first period was the year before the introduction of Milou, from 1st of October 2016 to 30th of September 2017, and the second period was after the introduction of Milou, from 1st of October 2018 to 30th of September 2019. There were 4,279 participants in the study comprising all women who received the diagnosis recording of fetal heart rate during labor and delivered a singleton in a cephalic postition, after 37 weeks of pregnancy at Landspítali‘s birth unit. Descriptive statistics were performed to describe both background and outcome variables. Analytical statistics were also performed, where both chi- square and t-tests were performed to assess differences between the study groups.
Results: There was no significant change in operative deliveries and emergency c-sections before and after the introduction of Milou at Landspítali‘s birth unit. In addition, there was no significant difference in the number of newborns with an Apgar score <7 at 5 minutes.
Conclusions: The use of the Milou central fetal monitoring system at Landspítali‘s birth unit has not resulted in an increase in obstetric intervention nor in better outcomes for newborns. It is necessery to remain vigilant of the effects of the Milou system on birth outcomes at Landspítali and further research is required on the topic.

Covering Covers: Characterization Of Visual Elements Regarding Sleeves
No full textThe aim of this work is to explore common traits preferred across different age groups of children to identify the appeal of book covers. By analyzing visual attributes, visible objects, and implied stories inferred from the covers, we can gain insights into the elements that are most attractive to children up to 18 years old. These findings can then contribute towards advancing personalization for recommender systems for children through new means that do not rely on historical data, seldom available for this user group.

Role of saturated covers as oxygen buffers in cold climates
No full text[T]his report explores a hybrid-applied solution: the use of saturated covers, which involve lifting an elevated water table into a tailing impoundment that maintains saturation within the tailing profile without allowing excess water directly along the surface of the embankment. The objective of this project is to evaluate the efficacy of saturated covers in Northern regions by testing oxygen diffusion in a series of experiments with two levels of saturation using an instrumented column. While there has been some research detailing the beneficial use of saturated covers, such as in the Oxygen diffusion in saturated covers methodology and literature review (Gagne Turcotte et al., 2020) completed prior to this lab scale study, the methodology used within this study relied heavily on prediction variables/models: De and Kr, but
these proved to be more complicated than expected (Gagne Turcotte et al., 2020). Additionally, mine tailings by nature are rather unique and each sample of tailings has its own unique characteristics that need to be accounted for. Thus, the creation of this methodology occurred, with a specific emphasis on applied methods.--from IntroductionPublication is a an outcome of the oxygen diffusion in saturated covers project
Assessment of Acculturation: Issues and Overview of Measures
No full textPublicly available acculturation measures are systematically reviewed based on three criteria: scale descriptors (name of the scale, authors, year, target group, age group, subscales, and number of items), psychometric properties (reliabilities) and conceptual and theoretical structure (acculturation conditions, acculturation orientations, acculturation outcomes, acculturation attitudes, acculturation behaviors, conceptual model and life domains). Majority of the reviewed acculturation measures are short, single-scale instruments that are directed to specific target groups. Additionally, they mainly assess behavioral acculturation outcomes than acculturation conditions and orientations. Regarding the psychometric properties; most measures have an adequate internal consistency; yet cross-cultural validity of the instruments have not been reported. Guidelines for choosing or developing acculturation instruments are provided in the chapter

Oxygen diffusion in saturated covers
No full textThe objective of this study is therefore to evaluate the impact of freeze-thaw cycles on oxygen migration within saturated covers over tailings, by simulating a tailings cover system in the laboratory through column experiments. Covers for waste rock are not evaluated, but may be the topic of future research. This report details the selection of experimental methodology, background literature, experimental design, and details the results of the column experiments.--from IntroductionPublication is an outcome of the Oxygen diffusion in saturated covers project.
Phase 2:
This study focused on oxygen concentration and unfrozen volumetric water content within freezing conditions through a series of laboratory column experiments and through an analysis of diffusion coefficients De and Kr, from Fick's first and second law. In order to create a representative model of freezing conditions for the numerical simulations, large instrumented columns were used with an inert material filling, and the evolution of the following parameters were monitored over time and depth: volumetric water content, unfrozen volumetric water content, temperature; and oxygen concentration gradient between the water interface and the top of the cover material (only the partially water-saturated portion)

Strength of grass covers on dikes
No full textWave overtopping is responsible for many dike failures, dike breaches and severe flooding. The erosion resistance of dikes to overtopping waves is determined by the strength of the grass cover. Therefore, a thorough understanding of the erosion resistance of grass covers is desired to enable a good and effective dike management. In the existing approach to assess the erosion resistance of grass covers, the erosion resistance is empirically quantified in terms of local hydraulic loads. However, despite the cyclical nature of overtopping waves, no insights into the dependence of the erosion resistance on successive loads are available. To improve the understanding of the resistance of grass covers to wave overtopping induced loads, understanding of the development of the mechanical behaviour of grass sods is essential. In this study the mechanical behaviour of grass covers under tensile loads have been examined by means of direct pull tests executed in the field. Especially the influence of repetitive wave loading and the conditions during testing were of interest. The results of this study show that the deformation of the grass cover due to tensile load is time dependent. The failure mode of the grass cover is influenced by the degree of saturation of the grass cover. The maximum strength and mechanical behaviour of the grass cover is influenced by accumulation of damage. The findings presented in this study provide a better understanding of the processes that influence the mechanical behaviour of the grass cover. Moreover, insights in the development of the process of damage accumulation are revealed. Based on the findings of this study, a method is proposed to determine the resistance of grass covers against repetitive loads by means of direct pull tests. In this method the resistance of grass covers against repetitive loads is described by an estimation of the fatigue limit. Relating the fatigue limit of a grass cover to hydraulic loads, enables an assessment of the erosion resistance of a grass cover at a specific location.Civil Engineer Consultancy ProjectCivil Engineering | Hydraulic Engineering | Hydraulic Structures and Flood Ris
From digital harm to recovery: a multidisciplinary framework for First Aid after Online Sexual Abuse
No full textOnline sexual abuse in adolescence encompasses various forms of digital exploitation, including grooming, sexting, sextortion, and image-based sexual abuse. Current research indicates that a significant proportion of minors are exposed to online sexual abuse. The psychological impact on victims includes severe mental health issues, such as depression, anxiety, and post-traumatic stress symptoms. Responses to online sexual abuse disclosures often require a multidisciplinary approach. In the Netherlands, Sexual Assault Centers (SACs) utilize the First Aid after Online Sexual Abuse protocol. This approach addresses immediate safety and (forensic) medical concerns, facilitates the removal of image-based content, and supports natural recovery while providing referrals for psychological treatment if needed. This paper highlights the urgent need for a comprehensive, multidisciplinary response to online sexual abuse, emphasizing the importance of integrating psychological, medical, and legal support to tackle the complex challenges posed by online abuse, ensuring effective, context-sensitive interventions, and supporting victims’ recovery and well-being
