The astronomical observations and calculations made at the lunar eclipse of 18 November 1584 in Mexico are analyzed with emphasis on the methods and calculations used. The observations were intended to determine the geographical longitude difference between Mexico City and Seville in Spain but due to several errors, the most important one being using the wrong time for the end of the eclipse in Se
Bone mineral density (BMD) measurements are widely used to estimate the risk of osteoporotic fractures. In addition, many other risk factors have been identified, sonic of which are known to add to the risk independently of BMD measurements. The combination of BMD with such risk factors increases the gradient of risk/standard deviation (SD) than that achieved by BMD alone. In this paper, we report
Serine protease inhibitors (Serpins) are involved in the pathogenesis of neurodegenerative dementia, including the two most common types, Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB). The pathological characteristics of AD include senile plaques, mainly composed of aggregated amyloid-beta peptide (Abeta1-42), but also serpins, and neurofibrillary tangles of hyperphosphorylated tau
The Amazon Rainforest is in grave danger of disappearing for good, due to a number of harmful economic activities, including land conversion for cattle ranching and monoculture, as well as unsustainable and illegal timber production. It has been shown, however, that the private sector has a crucial role in redressing socio-economic problems, causing deforestation and degradation. To illustrate thi
All over the arctic and sub-arctic region global warming is affecting permafrost. When permafrost thaws, organic material becomes available for decomposition, hence an increase of greenhouse gas emissions to the atmosphere. In the northernmost of Sweden, on a mire close to Abisko, a snow manipulation project is ongoing. The experiment is trying to mimic predictions of future conditions and advance
Orientation of Myriococcum thermophilum Cellobiose Dehydrogenase (MtCDH) immobilized on spectroscopic graphite electrodes has been investigated electrochemically through flow injection analysis in order to obtain more information about the DET efficiency of this enzyme. The effect of applied potential and the long term stability of the modified electrodes were determined, as well as the bioelectro
Objective: Previous studies have revealed positive effects on subjective alertness, performance and general sleep patterns, with exposure to light conditions adapted to time of day according to the circadian system. This study aimed to investigate the impact of a dynamic LED light intervention on sleep quality of adolescent students. Methodology: Twenty eight seventh-grade subjects were recruited
This study examines possible causal relationship between investments in research and development (R&D) and economic growth of the European Union (EU) regions using R&D per capita as a measure of innovation. Given the importance the EU policies have put on innovation in creating better economic outlook, questions whether investments in R&D are growth enhancing and efficient in promoting
The main purpose of this paper is to analyze different factors which have an impact on the level of financial constraints that companies face. The main factors that are discussed in this paper are the size of firms and the level of country development, measured by institutional development, development of financial markets and economic development. Whited-Wu index is used to calculate the level of
Thesis Purpose: The purpose of this study is to contribute to a further understanding of how managers of heritage brands within the arts and cultural sector can embrace co-creation activities to engage with and attract a broader segment of the market. Methodology: The Royal Danish Theatre serves as a single-case study. It is drawn on data that was generated using a qualitative research approach.
The Tomten-1 drilling at Torbjörntorp in Västergötland, southern Sweden, penetrated 29.85 m of Cambrian Series 2 and 3, Furongian, and Lower and Middle Ordovician strata. The biostratigraphy, sedimentology and carbon isotope (δ13Corg) stratigraphy of the core have been analysed. The succession is interrupted by numerous stratigraphic gaps (i.e. hiatuses) of variable magnitudes. There also appear t
The aim of the report was to investigate and compare the effect of horizontal projections along with different spandrel heights between the unprotected openings in the building facade. The effect was more specifically the effect on the risk level in regards to the external vertical fire spread. Furthermore, based upon the performance requirements of the Swedish building regulations (BBR), the aim
The purpose of this study is to examine whether an acquiring firm that operates as a contractor within the defence sector can expect to generate shareholder value from a merger and acquisition with a fellow defence sector competitor. Having selected thirty acquiring defence firms an event study utilizing the market model is performed to obtain the abnormal returns generated from a merger and acqui
Previous research has mainly addressed the impact of over/under-education on wages in developed countries. Therefore, this paper attempts to fill the void gap in the literature by empirically examining the impact of over-education and under-education on wages in a developing country, namely Egypt, using the 2012 Egyptian Labor Market Panel Survey (ELMPS). In order to do so, actual years of educati
Popular science The carbon balance of the forest ecosystems is determined by the uptake and release of carbon. Forests take up carbon dioxide (CO2) by photosynthesis and release by respiration. One part of the assimilated carbon is respired back to the atmosphere by vegetation. The other part is respired by soil microbes which decompose organic material in soil. The microbial respiration is contro
Background: Psilocybin-assisted therapy (PAT) shows promise in the treatment of a variety of mental disorders. To date, no meta-analysis has been conducted on the effect of PAT on quality of life (QOL). Methods: A systematic review and meta-analysis of clinical trials examining PAT and reporting on QOL, extracted from Embase, Medline, PsycInfo, Web of Science and Cochrane CENTRAL. Results: Across
This thesis investigates the evolving legal status of Sports Governing Bod-ies (SGBs) like UEFA and FIFA under EU law. It specifically questions whether their regulatory frameworks and practices align with EU competi-tion law and free movement principles. The research heavily relies on the analysis of recent pivotal court decisions, including the December Rulings and Diarra. The thesis begins by
Background Lifecycles of electronics are decreasing, whereas companies with long life product such as the automotive and defence industry is increasing electrification in their products. Consequently, the mismatch in lifecycles between the electronics industry and Original Equipment Manufacturers (OEMs), with long life products, requires a solid obsolescence management process, to mitigate and res
