Early vascular ageing is common in patients with hypertension and increased burden of cardiovascular risk factors, often influenced by chronic inflammation. One aspect of this vascular ageing is arterial stiffening, as measured by increased pulse wave velocity or augmentation index and central pressure. Several studies have indicated that this process starts early in life and that arterial functio
Prevailing winds carry seafarers across oceans and guide insects on their journeys. The South African, ball-rolling dung beetle Kheper lamarcki depends on a range of compass cues, including the azimuthal position of the sun and the directed airflow of wind to steer its plotted course. In this thesis, I set out to further our understanding for how these insects benefit from the directional componen
Manual segmentations are considered the gold standard for ground truth in machine learning applications. Such tasks are tedious and time-consuming, albeit necessary to train reliable models. In this work, we present a dataset with expert segmentations of the prostatic zones and urethra for 200 randomly selected patients from the PROSTATEx dataset. Notably, independent duplicate segmentations were
A relativistic transient absorption theory is derived, implemented and validated within the dipole approximation based on the time-dependent Dirac equation. In the non-relativistic limit, it is found that the absorption agrees with the well established non-relativistic theory based on the time-dependent Schrödringer equation. Time-dependent simulations have been performed using the Dirac equation
This qualitative theological study seeks to shed light on pentecostal theology and spirituality through an investigation of worship as it is practiced in two urban pentecostal-charismatic churches in Nairobi, Kenya. The empirical data serve as a springboard for theological construction and interpretation from a pentecostal perspective. In contemporary charismatic liturgy, the first section of the
I argue that the philosophy of Merleau-Ponty can help resolve a long-lasting problem, with continued relevance for philosophy, semiotics and linguistics: the dialectical relationship between pre-verbal consciousness and language. I proceed by reconstructing the development of his thought on the topic from the Phenomenology of Perception to his final writings. From an initial standpoint where langu
Context. With data releases from the astrometric space mission Gaia, exploration of the structure of the Milky Way is now possible in unprecedented detail, and has unveiled many previously unknown structures in the Galactic disc and halo. One such feature is the Gaia phase spiral where the stars in the Galactic disc form a spiral density pattern in the Z- VZ plane. Many questions regarding the pha
At key moments in history, political understanding and action are irrevocably transformed. What makes such moments of transformation possible? This article examines the emergence of African nationalism in South Africa, following the multivocal appeal to African nationhood made by proto-nationalist leaders and intellectuals. In doing so I examine how new political imagination can reconfigure the st
It is widely acknowledged that official surveillance and control over Chinese citizens have been intensifying since President Xi Jinping came to power in late 2012. What is alarming is the authorities’ vigorous promotion of a variety of channels for ordinary people watching and informing on each other in daily life. In recent years, the regime has systematically institutionalised mass reporting. T
Having found that carbonyl sulfide (COS), works well as a catalyst in the transformation of amino acids to polypeptides, we have now tested COS as a catalyst also for the formation of substances that might be thought of as partners in the building of RNA. The model used was selective energy transfer (SET). This model implies that a certain number of vibrational quanta are donated from the catalyst
Addressing climate change and the collapse of ecosystems without threatening the economy, while simultaneously improving the well-being of all people, and ensuring social justice and equality seems to be the largest challenge in the history of mankind. So far, all the efforts to address growing environmental and human problems through technological solutions and half-hearted policy measures have b
The aim of this paper is to begin a discussion on what role Environmental Humanities might play in policy-making, and in negotiating alternative ways of engaging with the environment in general, in the Faroe Islands. To approach these issues, it is necessary first to deal with what the absence of Environmental Humanities means in the Faroes and what Environmental Humanities would mean in a Faroese
Det finns vissa relativt enkla knep när det gäller att försvåra fusk i samband med online-examination på distans. Här nämner vi några stycken som kan vara värda att prova: Går det att bygga in element med en personlig vinkel i frågorna, där studenten måste reflektera eller relatera de ämnesmässiga kunskaperna till sådant som inte är lika för alla? Är det möjligt att lägga till en eller ett par f
Årskurs: 4-6, 7-9 Ämnesområde: Ljus och ljud Ögats näthinna reagerar på det ljus som kommer in i ögat. Näthinnan skickar signaler till hjärnan, detta är att se. Det finns emellertid delar av näthinnan som inte ger dig någon syninformation. Detta är ögats blinda fläck. Med hjälp av nedanstående experiment kan du räkna ut storleken på den blinda fläcken, visa att den finns och hur hjärnan kompense
