For more than a century the research on the Antikythera Mechanism engaged scientists from a widerange of scientific disciplines searching for clues, in order to solve the mystery that this unique ar-chaeological find poses. The results so far have been spectacular enough to re-write the History ofTechnology providing new aspects on the degree of technological sophistication and scientific de-velop
BACKGROUND: Malignant melanoma is the most deadly form of skin cancer. Female sex is known to have a protective effect on incidence, tumour characteristics, and mortality from melanoma. However, the potentially modifying effect of sex on the prognostic significance of clinicopathological and investigative factors is generally not taken into consideration in biomarker studies. In this study, we com
Tunnelling below water passages is a challenging task in terms of planning, pre-investigation and construction. Fracture zones in the underlying bedrock lead to low rock quality and thus reduced stability. For natural reasons, they tend to be more frequent at water passages. Ground investigations that provide information on the subsurface are necessary prior to the construction phase, but these ca
Animals, like humans, need to perceive their surroundings via their senses in order to make sensible behavioral decisions, reproduce successfully, and survive. Animals are equipped with audition, vision, thermosensation, hygrosensation, mechanosensation, magnetoception, gustation, and olfaction, which detects physical and chemical changes in their habitats. Among these senses, olfaction is likely
BACKGROUND: Most evidence for TSC-associated neuropsychiatric disorders (TAND) to date have come from small studies and case reports, and very little is known about TAND in adults. We explored baseline TAND data from the large-scale international TOSCA natural history study to compare childhood and adult patterns, describe age-based patterns, and explore genotype-TAND correlations.RESULTS: The stu
The importance of semi-arid ecosystems in the global carbon cycle as sinks for CO 2 emissions has recently been highlighted. Africa is a carbon sink and nearly half its area comprises arid and semi-arid ecosystems. However, there are uncertainties regarding CO 2 fluxes for semi-arid ecosystems in Africa, particularly savannas and dry tropical woodlands. In order to improve on existing remote-se
Some polycyclic aromatic hydrocarbons (PAH) are known carcinogens and workplace PAH exposure may increase the risk of cancer. Monitoring early cancer-related changes can indicate whether the exposure is carcinogenic. Here, we enrolled 151 chimney sweeps, 152 controls, and 19 creosote-exposed male workers from Sweden. We measured urinary PAH metabolites using LC/MS/MS, the cancer-related markers te
Fredrik N G Andersson diskuterar i bokens sjätte kapitel den gemensamma valutan eurons problem och framtid. Andersson påpekar att utmaningen för euron inte är nationalstatens återkomst utan att nationalstaten aldrig försvann. För att vinsterna med en gemensam valuta skall överstiga kostnaderna måste euroländerna förenas i en politisk union som gemensamt utformar regler för bland annat skatter, arb
BackgroundThe incidence of human papilloma virus (HPV)-related oral cancer has recently increased worldwide. The role of dentists is of prime importance in the early detection of oral cancer which would result in a favourable outcome for the patients. The aim of the current study was to assess the knowledge, awareness and attitudes of dental students, interns and postgraduate maxillofacial residen
OBJECTIVES: To examine the mortality pattern and the cancer incidence in a cohort of long term smelter workers exposed to lead.METHODS: The cohort consists of 664 male lead battery workers, employed for at least three months in 1942-87. From 1969 the values of all blood lead samples repeatedly obtained from these workers every two to three months, have been collected in a database. The expected mo
Biomarkers are used in molecular biology to predict characteristics of interest and are applied in agriculture to accelerate the breeding of target traits. Proteomics has emerged as a promising technology for improved markers by providing a closer view to the phenotype than conventional genome-based approaches. However, a major challenge for biomarker development is that the identified biological
Studien fokuserar på sociala- och organisatoriska aspekter av den digitala arbetsmiljön och hargenomförts av en pedagog och en datavetare i samverkan. Införandet av Canvas som lärplattform haranvänts för att studera implementeringen av ett nytt system som en del av lärares arbetsmiljö.Med material från intervjuer och observationer ges en beskrivning av hur universitetslärararbetetunderlättats och
Pollination is a key ecosystem service for global agriculture but evidence of pollinator population declines is growing. Reliable spatial modelling of pollinator abundance is essential if we are to identify areas at risk of pollination service deficit and effectively target resources to support pollinator populations. Many models exist which predict pollinator abundance but few have been calibrate
Osteoarthritis of the carpometacarpal joint at the base of the thumb (CMC1 OA) is common and causes difficulty in grasp, grip, and fine manipulation of the hand. Surgery is recommended after failure of non-operative treatment, andevidence from short and medium-term follow-up studies shows successful relief of pain and return of function. Previous investigations of epidemiology and risk factors wer
There is an extensive research that explores the reproduction of transnational communities and relations, with a particular focus on locality, identity and culture. However, the existing research emanates from the case studies of immigrant communities in Western-type democracies, while we know little about migrant transnationalism in non-Western migration regimes such as Russia, where migrant work
This work provides new insights into the presence of 239Pu, 240Pu, 241Pu, and 236U in the Southern Hemisphere through the study of peat bog cores from marshlands in Madagascar (19°S). 210Pb, 238Pu and 239+240Pu activities were characterized by alpha spectrometry in previous studies. Here, Pu from alpha-spectrometry discs corresponding to 10 peat-bog cores (85 samples) was reassessed for the aim of
PURPOSE: The prevalence of iron deficiency (ID) in Left Ventricular Assist Device (LVADs) recipients is not known nor has the association between ID and peak oxygen uptake (VO2) been reported. The aim of this study was to study to investigate the prevalence of ID in this population and the association between ID and VO2. METHODS: Data was included from LVAD recipients at Rigshospitalet, Denmark (D
Unstructured citizen-science data are increasingly used for analysing the abundance and distribution of species. Here we test the usefulness of such data to predict the seasonal distribution of migratory songbirds, and to analyse patterns of migratory connectivity. We used bird occurrence data from eBird, one of the largest global citizen science databases, to predict the year-round distribution o
