Implications of burial alterations on luminescence dating of archaeological ceramics

Recent mineralogical studies on archaeological pottery samples report significant variations in alkali metal concentrations due to environmental alterations during burial. Here we examine the effects of potassium (K) leaching on luminescence dating. The effect on the estimation of the dose rate is studied by considering four models of leaching (exponential, linear, early and late) and their impact on fine- and coarse-grain dating are calculated. The modeling approaches are applied to two cases of pottery in which evidence for alteration was found. Additionally, TL dating performed on pottery of one of the studied cases, indicates the importance of leaching effects on absolute dating measurements.

Planering av tidtabell, kostnader och arbetsplats för småhus

Det här examensarbete gjordes åt Seasong Travels Oy. I arbetet gjordes en kostnadsplan, tidtabell och dispositionsplan för en stugby på Norrkullalandet. Arbetet börjades med att bekanta sej med byggbranschens facklitteratur och ta reda på vilka faktorer som påverkar byggprojektets slutliga kostnader och tidtabell. På basen av områdets litteratur valdes kostnadsberäkningssättet att utföras med hjälp av Talo-80 nomenklatur och göra en byggnadsdelskalkyl. I arbetets undersökningsskede delades stugorna upp enligt Talo-80 nomenklatur i enskilda byggnadsdelar, varefter byggnadsdelarna prissattes. En tidtabell gjordes när alla byggnadsdelar var uppdelade och med hjälp av områdets litteratur räknades den effektiva byggtiden ut. Dispositionsplanen gjordes genom att studera områdets facklitteratur och själva byggplatsen.

Aneurisma venoso na junção esplenomesentérica e emergência da veia porta: relato de caso

Os aneurismas no sistema esplenoportomesentérico são uma entidade clínica rara e de etiologia desconhecida, tendo como fatores contribuintes hipertensão portal, doença hepática crônica e trauma, entre outros. Os autores apresentam os achados de imagem de um caso de aneurisma na junção esplenomesentérica ao nível da emergência da veia porta, em uma paciente de 62 anos de idade sem fatores predisponentes.

Worldwide trends in diabetes since 1980: a pooled analysis of 751 population-based studies with 4.4 million participants.

One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age-standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are affecting the number of adults with diabetes. We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosis with diabetes, or use of insulin or oral hypoglycaemic drugs-in 200 countries and territories in 21 regions, by sex and from 1980 to 2014. We also calculated the posterior probability of meeting the global diabetes target if post-2000 trends continue. We used data from 751 studies including 4,372,000 adults from 146 of the 200 countries we make estimates for. Global age-standardised diabetes prevalence increased from 4.3% (95% credible interval 2.4-7.0) in 1980 to 9.0% (7.2-11.1) in 2014 in men, and from 5.0% (2.9-7.9) to 7.9% (6.4-9.7) in women. The number of adults with diabetes in the world increased from 108 million in 1980 to 422 million in 2014 (28.5% due to the rise in prevalence, 39.7% due to population growth and ageing, and 31.8% due to interaction of these two factors). Age-standardised adult diabetes prevalence in 2014 was lowest in northwestern Europe, and highest in Polynesia and Micronesia, at nearly 25%, followed by Melanesia and the Middle East and north Africa. Between 1980 and 2014 there was little change in age-standardised diabetes prevalence in adult women in continental western Europe, although crude prevalence rose because of ageing of the population. By contrast, age-standardised adult prevalence rose by 15 percentage points in men and women in Polynesia and Micronesia. In 2014, American Samoa had the highest national prevalence of diabetes (>30% in both sexes), with age-standardised adult prevalence also higher than 25% in some other islands in Polynesia and Micronesia. If post-2000 trends continue, the probability of meeting the global target of halting the rise in the prevalence of diabetes by 2025 at the 2010 level worldwide is lower than 1% for men and is 1% for women. Only nine countries for men and 29 countries for women, mostly in western Europe, have a 50% or higher probability of meeting the global target. Since 1980, age-standardised diabetes prevalence in adults has increased, or at best remained unchanged, in every country. Together with population growth and ageing, this rise has led to a near quadrupling of the number of adults with diabetes worldwide. The burden of diabetes, both in terms of prevalence and number of adults affected, has increased faster in low-income and middle-income countries than in high-income countries. Wellcome Trust.

Matkustus Suomessa : ensimmäinen jakso

Suomalainen maisema esitellään tässä teoksessa ajan tunnetuimpien suomalaisten taiteilijoiden näkemänä; teosta varten tilattiin A. v. Beckerin, A. Edelfeltin, R. V. Ekmanin, W. Holmbergin, E. Janssonin, O. Kleinehin, J. Knutsonin, B. Lindholmin, Hj. Munsterhjelmin ja B. Reinholdin maisemamaalaukset. Näiden maalausten pohjalta kaiverrettiin ulkomailla teräspiirrokset kirjan painotyötä varten.

Maisemia ja nähtävyyksiä kuvaavat selitystekstit ovat Topeliuksen kirjoittamia. Kuvauskohteiden painopiste on rannikkoseudulla, sillä julkaisulle oli suunniteltu jatko-osia, jotka eivät kuitenkaan toteutuneet. Teoksessa pyrittiin antamaan entistä todenmukaisempi kuva Suomesta. Teos oli tarkoitettu myös Suomi-kuvan luojaksi ulkomailla; teksti julkaistiin saksaksi, ranskaksi ja englanniksi. Teoksesta ilmestyi myös ruotsinkielinen laitos.

Finland framstäldt i teckningar

Zacharias Topeliuksen (1818-1898) Finland framstäldt i teckningar oli ensimmäinen kokonaisesitys Suomen maisemista lounaissaaristosta tunturimaisemaan. Sen esikuvana olivat muissa Euroopan maissa julkaistut vastaavat teokset, jotka lisäsivät lukijoiden tietoisuutta oman maan kauneudesta ja historiallisesta merkityksestä. Myös Topeliuksen teoksella oli suuri merkitys suomalaisten isänmaakäsityksen kehittymiseen. Teokseen liittyy 120 historiallisesti, maantieteellisesti tai muuten merkittävää paikkaa tai rakennusta esittävää kivipiirrosta, joiden tekijöinä olivat tunnetut taiteilijat, kuten Lennart Forstén, Magnus von Wright, P. A. Kruskopff ja Johan Knutson. Kirjan laaja teksti on Topeliuksen seikkaperäinen kuvaus maisemakohteista, maan ja kansan historiasta.
