The purpose of this work is to indicate the actinides input to the total radiation dose caused by the irradiated graphite of the RBMK-1500 reactor in comparison to the dose delivered by other nuclides. We used computer codes (SCALE 6.1 and MCNPX 2.7) to estimate the dose rate delivered by actinides giving special attention to the 244
Telomerase maintains telomere length and chromosome integrity by adding short tandem repeats of single-stranded DNA to the 3' ends, via reverse transcription of a defined template region of its RNA subunit. To further understand the telomerase elongation mechanism, we studied the primer utilization and extension activity of the telomerase from the budding yeast Naumovozyma castellii (Saccharomyces
This paper aims to explore how learning about Circular Economy (CE) may be facilitated through the use of the serious game In the Loop. Despite the growing literature base related to CE, academic reflection on education for a CE is currently limited. In the Loop was developed to provide an experiential learning situation for educating about material criticality and CE. This study reflects on the u
The aim of this thesis is develop methods to extract information from high-dimensionality data and to apply them in looking at gene-gene and gene-protein interactions in Acute Myeloid Leukemia (AML). The in silico methods developed can be used with data from other systems. The thesis gives an overview of the field for network inference and deconvolution methods, as well as a brief background on th
The paper considers multi-hop wireless mesh networks that serve multicast periodic packet traffic. The packets from each packet stream are generated at the stream's source node and traverse a number of wireless nodes in order to reach their multiple destination nodes. Packet periodicity means that a common repeatable frame of time slots is defined and that the packets to be transmitted arrive at t
PURPOSE: Epinephrine is used in local anesthetics to induce vasoconstriction and thus reduce bleeding and prolong the anesthetic effect. Finding the optimal delay between the administration of the anesthetic and skin incision to ensure vasoconstriction and minimize bleeding is important and has recently become the subject of debate. This is the first study to assess blood perfusion and oxygen satu
West African Sahelian and Sudanian ecosystems provide essential services to people and also play a significant role within the global carbon cycle. However, climate and land use are dynamically changing, and uncertainty remains with respect to how these changes will affect the potential of these regions to provide food and fodder resources or how they will affect the biosphere-atmosphere exchange
The role of proteins as the mediators of the interaction between engineered materials (biomaterials) and living systems has long been appreciated, but the subtleties and complexities introduced by changing surface curvature are only beginning to be understood. Thus, in implant devices, where the biomaterial is presented as a flat surface, a very limited range of proteins bind to the material, thes
Purpose: Monte Carlo (MC) modelling techniques can assess the quantitative accuracy of both planar and SPECT Nuclear Medicine images. It is essential to validate the MC code's capabilities in modelling a specific clinical gamma camera, for radionuclides of interest, before its use as a clinical image simulator. This study aimed to determine if the SIMIND MC code accurately simulates emission image
Abstract Purpose: To evaluate the midterm outcomes and potential risk factors associated with the fascia suture technique (FST) for closure of femoral artery access sites after percutaneous endovascular aneurysm repair (EVAR). Methods: Between April 2007 and April 2008, 100 consecutive EVAR cases were evaluated retrospectively. A third of the procedures were emergent (16 ruptured aneurysms). Of th
The gradient of five dansylated amino acids in a capillary-based separation system commonly used in capillary liquid chromatography (LC) or capillary electrochromatography (CEC) was followed and examined in detail using a detection method based on laser-induced fluorescence imaging. The detection system consisted of an XeCl excimer laser and an image-intensified charge-coupled device (CCD) camera.
Background: Motor fluctuations are routinely documented using the Parkinson's disease (PD) home diary. However, the validity of this diary when compared to clinical observers is limited. Objective: This study disassembled the effects of nonmotor symptoms (NMS) on inter-method agreement between the PD home motor diary and clinical observers (outside validity criterion). Methods: A prospective obser
Two-level systems (TLSs) are the basic units of quantum computers but face a trade-off between operation speed and coherence due to shared coupling paths. Here, we investigate a TLS given by a singlet-triplet (ST+) transition. We identify a magnetic-field configuration that maximizes dipole coupling while minimizing total dephasing, forming a compromise-free sweet spot that mitigates this fundamen
This contribution explores the attempts by international humanitarian agencies and the post-genocide Rwandan state respectively to deal with exceptionality created by the genocide and return to normality. It does so by comparing two kinds of camps that deal with exceptional life: the refugee camps for Hutu who fled after the genocide and the Rwandan government's ingando re-education camps. While t
Habitat area, forest characteristics, management practices and protected areas have the potential to profoundly impact biodiversity. This is particularly true for specialist species linked to structural complexity and old forest, like the lesser spotted woodpecker (Dryobates minor). This study examines how habitat quality and quantity influence the occurrence of this Near-Threatened species across
In order to understand and manipulate biological function at the molecular level, access to high-resolution structures of biological macromolecules is essential, as structure is intimately linked to function. The two main experimental techniques that can achieve atomic, or near-atomic, resolution are crystallography and electron microscopy. Unfortunately, the experimental data alone is typically n
Background: There was a global epidemic of methylchloroisothiazolinone (MCI) and/or methylisothiazolinone (MI) contact allergy from 2009 to 2015. In response, the Thai Ministry of Public Health regulated the use of MCI/MI in cosmetics. Objective: To survey the presence of MCI/MI and MI alone, as labelled on cosmetics sold on the Thai market, before and after the ministerial directive. Methods: The
