Groundwater contamination by nitrate is a common problem in many parts of the world. The agriculturally important Shimabara district in Nagasaki, Japan, is experiencing this problem. The general source of drinking water of the study area is groundwater and consequently the nitrate contamination is a significant problem. For this reason, a groundwater investigation was performed and water samples w
Kraven gällande maximalt tillåtna gångavstånd till en utrymningsväg saknar förmodligen en direkt vetenskaplig grund. De är dock resultatet av många års byggande där historien visat vad som fungerat. Exakt vad som givit upphov till gångavstånden är fortsatt okänt och det skulle således kunnat vara en praktisk fråga gällande vad som var möjligt att bygga, lika väl som hur stora avstånd städpersonal The allowed travel distance has probably not been determined scientifically. Yet it indirectly takes a number of factors into account and should therefore not only be seen as a distance that takes a certain time to walk, but also as a certain level of safety. Longer travel distances do extend the walking time but it also makes it possible for a series of factors to increase the risk. The factors t
This report is a result of a Master Thesis project made by Anna Håkansson and Lisa Carlson, two students from Mechanical Engineering with the specialization Product Development. The project was made at Axis Communications AB at the Department of Mechanics in interaction with the Division Machine Design at the Department of Design Science, Faculty of Engineering (LTH), Lund University. Axis Commun
To specify the incidence and risk factors for secondary autoimmune diseases (ADs) after HSCT for a primary AD, we retrospectively analyzed AD patients treated by HSCT reported to EBMT from 1995 to 2009 with at least 1 secondary AD (cases) and those without (controls). After autologous HSCT, 29 of 347 patients developed at least 1 secondary AD within 21.9 (0.6-49) months and after allogeneic HSCT,
We used allozymes to investigate the structure of genetic variation in populations of the perennial herb Silene nutans at local (Denmark), regional (Nordic area) and wide (over a 19A degrees latitudinal gradient) geographic scales in north-western Europe. New data from Denmark were combined with data from previously studied Fennoscandian and western populations. We related patterns of nuclear vari
We present a review of elemental abundances in the Milky Way stellar disk, bulge, and halo with a focus on data derived from high-resolution stellar spectra. These data are fundamental in disentangling the formation history and subsequent evolution of the Milky Way. Information from such data is still limited and confined to narrowly defined stellar samples. The astrometric Gala satellite will soo
The formation of soot particles has been investigated in CH4/O-2 diffusion flames using a unique burner design, which allows the creation of a nearly unstrained planar reaction sheet. Spatially resolved soot volume fractions were obtained using laser-induced incandescence. These soot measurements and the sooting limits were obtained as a function of bulk flow across the flame and mixture strength.
The radionuclide (210)Po is of importance from a radiation protection view and has properties that cause special problems when attempting to determine the body content in humans. Estimates have traditionally been made from either urine and/or fecal samples, which require a time-consuming radiochemical preparation before alpha spectrometric determination. In order to find a more simple and less lab
We examine energy and CO2 intensities (energy use / GDP and CO2 emissions / GDP) in Sweden and Spain during the last two hundred years. The first aim is to establish reliable and comparable time-series. We include all energy that involves some human effort in its capture. Therefore, not only do we include modern energy carriers such as coal, oil, and electricity, but also we aim to account for fir
© 2017 Informa UK Limited, trading as Taylor & Francis Group Earlier studies have clarified that NADH and NADPH, re-energized repeatedly by red blood cell (RBC) glycolysis, can be used in extracellular chemical reactions, where electron energies are extracted by electron mediators, such as methylene blue (MB). The electron mediators, which are reduced by NAD(P)H, permeate both the membranes
Background: The International Federation of Gynecology and Obstetrics (FIGO) ovarian cancer staging system includes no sub-stage for lymph nodes (LN) as only distant disease manifestation. We explore the prognostic implication of LN as only stage IV classifier in serous ovarian cancer. Method: This is a nation-wide, population-based study on 551 women with serous stage IV cancers diagnosed between
BACKGROUND: Genes continuously duplicate and the duplicated copies remain in the genome or get deleted. The DAL5 subfamily of transmembrane transporter genes has eight known members in S. cerevisiae. All are putative anion:cation symporters of vitamins (such as allantoate, nicotinate, panthotenate and biotin). The DAL5 subfamily is an old and important group since it is represented in both Basidio
The Gaia-ESO Survey was designed to target all major Galactic components (i.e. bulge, thin and thick discs, halo and clusters), with the goal of constraining the chemical and dynamical evolution of the MilkyWay. This paper presents the methodology and considerations that drive the selection of the targeted, allocated and successfully observed Milky Way field stars. The detailed understanding of th
Sweden is renowned for its centralised wage bargaining system, which has been studied from the point of view of inflation, wage differentials and unemployment. This article studies media coverage of wage bargaining rounds in the 1950s–1960s and in the 2000s–2010s to investigate the social understanding of what the wage bargaining institutions are supposed to do. The results indicate that the opera
The packaging solution for freeze-dried adventure food has not changed for a long time. Across the market, the available models look very similar, and differ only in branding and fine detail. With help from concept developers at AR Packaging, and based on interviews with a group of extreme athletes which are the intended users of the product, the package was analysed to see where it can be improve
Popular Abstract in Swedish Idag har kravet på kortare ledtider i bilindustrin dramatiskt ökat behovet av effektivare utvecklingsmetoder vid varje steg i processutvecklingskedjan. För att minska de långa ledtiderna för framtagning av ett formningsverktyg har man introducerat Finita Element (FE) simulering av formningsprocessen. Även om FE-simulering används inom bilindustrin idag finns fortfarandeToday, shortened lead-times in the automotive industry have dramatically increased the need for more efficient development methods at every stage of the process development chain. In order to decrease the long lead-time for producing a forming tool, sheet-metal-forming simulation was introduced. Even though sheet-metal-forming simulation is widely used in the automotive industry today, there are s
The 19th century rise of history as an academic discipline set new standards for acceptable methods of writing history. This greatly influenced the opinions historians held of older historical works, such as the Historia de omnibus Gothorum Sueonumque regibus (History of all the Kings of the Goths and the Swedes) by the Swedish archbishop Johannes Magnus (1488-1544). The work has been criticised f
HIV infection affects the course of tuberculosis (TB), and HIV and Mycobacterium tuberculosis (Mtb) synergize in disease progression through complex immunological interplay. To gain further understanding of these mechanisms, we compared the microRNA (miRNA) and small nucleolar RNA (snoRNA) expression patterns in whole blood of individuals with active TB, with and without HIV coinfection (HIV+/TB+
We present a model featuring heterogeneous households with a conspicuous consumptionmotive, in which inequality can decrease financial stability, and relate this behavior to the recent financial crisis in theUSA. A natural policy conclusion would be to combat income inequality jointly with financial instability by means of a progressive system of taxes and transfers. We investigate this for the ca
