The nematophagous fungus Arthrobotrys oligospora produced extracellular proteases when grown in a liquid culture, as revealed by measuring the hydrolysis of the chromogenic substrate Azocoll. The extracellular protease activity was inhibited by phenylmethylsulfonyl fluoride (PMSF) and other serine protease inhibitors and partly inhibited by the aspartate protease inhibitor pepstatin and by a cyste
The lower Borgarfjörður region, western Iceland, has been central to the reconstructions of the dynamics and collapse of the Icelandic Ice Sheet during the deglaciation. Here, extensive stratigraphical sections and landforms provide a rare opportunity to study past glacier dynamics in this part of Iceland. Previous studies reveal that a large outlet glacier in Borgarfjörður advanced during the Lat
A sediment sequence from a small forest lake in southwestern Sweden was investigated to explore the effects of forestry and land-use on catchment erosion and delivery of organic and minerogenic matter to the lake. Catchment-scale vegetation changes during the last 1,100 years were reconstructed quantitatively at 50-year resolution using pollen analysis and the Landscape reconstruction algorithm (L
The so-called “dot-compartment” is conjectured in diffusion MRI to represent small spherical spaces, such as cell bodies, in which the diffusion is restricted in all directions. Previous investigations inferred its existence from data acquired with directional diffusion encoding which does not permit a straightforward separation of signals from ‘sticks’ (axons) and signals from ‘dots’. Here we com
Iron can be a growth‐limiting nutrient for phytoplankton, modifying rates of net primary production, nitrogen fixation, and carbon export ‐ highlighting the importance of new iron inputs from the atmosphere. The bioavailable iron fraction depends on the emission source and the dissolution during transport. The impacts of anthropogenic combustion and land use change on emissions from industrial, do
The aldosterone binding in isolated distal convoluted and cortical collecting tubules of renal nephrons and the influence of hormonal induction on the Na, K-ATPase activity in membrane fraction of kidney cortex were studied in 10-day- and 2-month-old rats. No reliable difference in aldosterone-specific binding was revealed (0.26 +/- 0.04 and 0.22 +/- 0.03 fmol/mm of tubule length, respectively, at
The influence of standard language varieties on rural dialects is an important factor involved in dialect loss, which is widespread in Europe. In this study, we look at how the three-gender system in the Jämtlandic dialect of Sweden is changing under pressure from the two-gender system of Standard Swedish. The Jämtlandic dialect is an understudied Swedish dialect and an interesting object of study
The relative environmental impact from the building construction phase is increasing compared to the operation phase for new buildings. Therefore, it is important to consider the complete environmental life cycle of energy improvement measures. Many advanced optimization methods have been developed in recent years to assess building life cycle impact. However, these previous studies have not fully
Practitioners may face difficulties in the interpretation of fire codes since they often present so called "magic numbers", i.e. numbers available in the codes which are listed for providing the design of building fire safety, for which the derivation and justification are not explained. The present paper discusses the need for a transparent regulatory approach, in which legislators publicly justi
The summed probability distribution of 162 radiocarbon dates from Gotland was analysed with reference to archaeological and environmental data in order to evaluate possible variations in settlement intensity on the island. The data indicated variations in demographic development on the island, with probably several different colonization events and external influences; the pioneer settlement reach
This thesis delves into two ‘edge areas’ located in and around East Jerusalem. It attempts to unfold and analyze the dynamics in these edge areas, while investigating the agency of the people present there through their own perceptions and practices towards the land, the urbanization processes, the power circulation and the structural impositions. Squeezed by a settler-colonial domination that con
The highly eroded 23 km diameter Rochechouart impact structure, France, has extensive evidence for post-impact hydrothermal alteration and sulphide mineralisation. The sulphides can be divided into four types on the basis of their mineralogy and host rock. They range from pyrites and chalcopyrite in the underlying coherent crystalline basement to pyrites hosted in the impactites. Sulphur isotopic
Platform ecosystems are becoming the locus of innovation-driven economies as technology-based platform within the ecosystem acts as the foundation for innovative product and services developed by the networked business community around that platform. At its core, a technology platform shows architectural properties, which once emerged in an industry could play as the de facto template for defining
The top quark mass is measured in the tt̄ → dileptonchannel (lepton=e, µ) using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton-proton centre-of-mass energy of √s=8 TeV and correspond to an integrated luminosity of about 20.2fb-1. Exploiting the template method, and using the distribution of invariant masses of lepton-b-jetpairs, the top quark mass is measured to b
Background: Studies have shown conflicting associations between the salivary amylase gene (AMY1) copy number and obesity. Salivary amylase initiates starch digestion in the oral cavity; starch is a major source of energy in the diet. Objective: We investigated the association between AMY1 copy number and obesity traits, and the effect of the interaction between AMY1 copy number and starch intake o
OBJECTIVES: The 22 countries of the East Mediterranean Region (EMR) have large populations of adolescents aged 10-24 years. These adolescents are central to assuring the health, development, and peace of this region. We described their health needs.METHODS: Using data from the Global Burden of Disease Study 2015 (GBD 2015), we report the leading causes of mortality and morbidity for adolescents in
