The REVEALS model was developed to reconstruct quantitatively regional vegetation abundance (in a 10(4)-10(5) km(2) area) from pollen assemblages in large lakes (>= 100-500 ha). This model corrects for biases in pollen percentages caused by inter-taxonomic differences in pollen productivity and dispersal. This paper presents the first case study to validate REVEALS, using empirical data from south
To describe incidence, risk factors, and influence of treatment on occurrence of central nervous system (CNS) relapse or progression in younger patients with aggressive B-cell lymphoma. We analyzed 2210 patients with aggressive B-cell lymphoma treated on various studies for CNS relapse/progression. Treatment consisted of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) +/- etoposi
Increasing precipitation and surface water temperature due to global change may strengthen the salinity gradient in coastal regions, which could influence the behaviour of dinoflagellate migration. We studied diel vertical migration (DVM) behaviour in the dinoflagellates Prorocentrum minimum and Heterocapsa triquetra using vertically stratified laboratory columns with 3 different salinity gradient
This paper investigates different retrofit solutions simulated in a commercial building from the 1960s. All improvements were simulated in the IDA ICE software and the Global Warming Potential was calculated with the help of Eco Bat. During the investigation a cost-effective solution was indicated with the help of a life cycle cost calculation. Then the environmental impact of each proposal was es
The preferred method for synthesising therapeutic peptides today is by Solid-Phase Peptide Synthesis (SPPS). SPPS is a wasteful process, where the main component of the waste is hazardous solvents, i.e., N,N-dimethylformamide (DMF), N-methylpyrrolidone (NMP) or dichloromethane (DCM). 3 It is therefore desirable to search for new and greener solvents to use for SPPS, which is what has been studied

Abstract The aim of this research was to peruse the verdicts of custody disputes were violence against the mother has occurred. In 2005, a study by Barnombudsmannen presented a result that showed that 43 % of custody disputes were domestic violence occurred was convicted joint custody. The result leaded to a restriction of Swedish family law in 2006. This study therefor aims to examine how the cou
Young girls and boys in Sweden can be ordered to compulsory care by the Administrative court if they are in psychosocially problematic situations. The purpose of our paper was to analyze how the socially destructive behavior of girls and boys was constructed in verdicts made by judges at the Administrative court. With a qualitative textual analysis we analyzed what kind of acts and social situatio
Inadequate water infrastructural development and high costs of water are few of the many challenges that affect water access in Kibera. Consequently, many alternatives to piped water grew out of necessity to meet the needs of residents. The aim of this thesis is to examine the conditions that have led to poor water provision in Kibera and how transitions to improved water access can be achieved by
Lynch syndrome (LS) is an autosomal dominant syndrome that predisposes individuals to development of cancers early in life. These cancers are mainly the following: colorectal, endometrial, ovarian, small intestine, stomach and urinary tract cancers. LS is caused by germline mutations in DNA mismatch repair genes (MMR), mostly MLH1 and MSH2, which are responsible for more than 85% of known germline
The production of nitrogen fertilizers are almost exclusively based on fossil feedstocks such as natural gas and coal. Nitrogen fertilizers are a necessity to maintain the high agricultural production that the world's population currently demands. Ammonia produced from nonfossil-based feedstocks would enable renewable production of ammonia. Renewable feedstocks are one thing, but perhaps even more
Oxygen binding and cleavage are important for both molecular recognition and catalysis. Mn-based porphyrins in particular are used as catalysts for the epoxidation of alkenes, and in this study the homolytic cleavage of O-2 by a surface-supported monolayer of Mn porphyrins on Ag(111) is demonstrated by scanning tunneling microscopy, X-ray absorption, and X-ray photoemission. As deposited, {5,10,15
Objectives: Analysis of fetal arterial and venous Doppler predictability for adverse perinatal outcome. Methods: Blood flow in the uterine, umbilical and middle cerbral arteries, umbilical vein, ductus venosus and Galen vein were examined with in 72 h of delivery in 88 high-risk pregnancies. The managing clinicians were only informed about the results of the umbilical artery Doppler. The Doppler r
The effects of extracts from five cultivars of strawberries on the proliferation of colon cancer cells HT29 and breast cancer cells MCF-7 were investigated, and possible correlations with the levels of several antioxidants were analyzed. In addition, the effects of organic cultivation compared to conventional cultivation on the content of antioxidants in the strawberries and strawberry extracts on
The aim of this study was to assess the role of videofluoroscopy in the detection of structural abnormalities of the pharynx and esophagus in patients with different symptoms of impaired deglutition. Dynamic radiographic recording of deglutition was performed in 3193 consecutive patients (1578 men, 1615 women; mean age 54 years) suffering from dysphagia, suspicion of aspiration, globus sensation,
