Modelling reactive solute transport from groundwater to soil surface under evaporation

Two-stage soil column experiments involving capillary rise and evaporation were conducted to improve understanding of salt and water movement from groundwater to soil surface. In total, 64 soil columns were placed in a tank partly filled with water in order to mimic the groundwater table in soil. Each soil column was analysed by dividing it into 27 segments to analyse pore water and ion distributi

Awakening the Sufferers: Reflections on Public Relations, Activism, and Subalternity in Postcolonial Controversies between Taiwan and Japan

This article is a qualitative analysis of mass-mediated projections of relationships between public relations practitioners in the shape of activist groups and organizations, and subaltern stakeholders for whom they act as public representatives. Drawing my empirical examples from Japan and Taiwan and analysing the public relations implications of two politically sensitive and controversial cases,

How design process for the Base of the Pyramid differs from that for the Top of the Pyramid

The base (BOP) and the top (TOP) of the world income pyramid represent the poor people and the people from developed countries, respectively. The design of products for the BOP is an important ingredient of the poverty reduction approach that combines business development with poverty alleviation. However, the current understanding of the design for the BOP is limited. This study, using a protocol

Effects of nitrogen fertilization on the forest floor carbon balance over the growing season in a boreal pine forest

Boreal forests play a key role in the global carbon cycle and are facing rapid shifts in nitrogen availability with poorly understood consequences for ecosystem function and global climate change. We quantified the effects of increasing nitrogen availability on carbon fluxes from a relatively understudied component of these forests - the forest floor - at three intervals over the summer growing pe

Gas6 is complexed to soluble tyrosine kinase receptor Axl in human blood.

Summary Background: The vitamin K-dependent Gas6 protein (product of growth arrest specific gene 6) binds to, and activates the TAM receptor tyrosine kinases Tyro3, Axl, and Mer. Gas6 and the TAM receptors have been suggested to be important for primary platelet functions, but Gas6 cannot be found in human platelets. However, Gas6 is present in human plasma at a concentration of around 0.2 nM, whi

Spatially resolved Hall effect measurement in a single semiconductor nanowire

Efficient light-emitting diodes and photovoltaic energy-harvesting devices are expected to play an important role in the continued efforts towards sustainable global power consumption. Semiconductor nanowires are promising candidates as the active components of both light-emitting diodes and photovoltaic cells, primarily due to the added freedom in device design offered by the nanowire geometry. H

Platelet shedding of CD40L is regulated by matrix metalloproteinase-9 in abdominal sepsis.

Background and objectives: Platelet-derived CD40L is known to regulate neutrophil recruitment and lung damage in sepsis. However, the mechanism regulating shedding of CD40L from activated platelets is not known. We hypothesized that matrix metalloproteinase-9 might cleave surface expressed CD40L and regulate pulmonary accumulation of neutrophils in sepsis. Methods: Abdominal sepsis was induced by

Acoustofluidics 8: Applications of acoustophoresis in continuous flow microsystems

This acoustofluidics tutorial focuses on continuous flow-based half wavelength resonator systems operated in the transversal mode, where the direction of the primary acoustic force acts in plane with the microchip. The transversal actuation mode facilitates integration with up- and downstream microchannel networks as well as visual control of the acoustic focusing experiment. Applications of parti

Flame structure analysis for categorization of lean premixed CH4/air and H-2/air flames at high Karlovitz numbers: Direct numerical simulation studies

This paper presents direct numerical simulation studies of lean CH4/air and H-2/air flames at high Karlovitz numbers utilizing detailed chemical kinetic mechanisms. Identical Karlovitz numbers are applied to the two flames; however, as the interaction of high turbulence intensity small scale structures with the reaction zones is considered, a significant difference in the effect of the turbulence

Variation in allergen content over time of acrylates/methacrylates in patch test preparations

P>Background Acrylates/methacrylates are volatile substances. There might be a gradual decrease in acrylate/methacrylate allergen content over time in patch test preparations but this has not yet been documented. Objectives To determine the allergen content of acrylates/methacrylates in patch test preparations over time under different storage conditions. Methods Five acrylate/methacrylate allerge

The dawn of terrestrial ecosystems on Baltica: First report on land plant remains and arthropod coprolites from the Upper Silurian of Gotland, Sweden

Abstract in UndeterminedSporangia, with their in situ cryptospores, spore masses, and a possible axis were identified in marginal marine Ludlovian deposits from Gotland. Sweden by means of light- and scanning electron microscopy.The sporangia identified are elongate, with fragments of the sporangia covering preserved, and contain well-preserved in situ embryophyte cryptospores identified as Laevol

Spatio-temporal patterns of intentional fires,social stress and socio-economic determinants: A case study of Malmö,Sweden

Since the end of the 1990s, the number of fires has increased dramatically in Malmö, a city in the southernmost part of Sweden. Between 1998 and 2009, the increase was 215%, and a large number of the fires were intentional. The aim of this paper is to deepen our understanding of the underlying causes of the spatial and spatio-temporal distribution of intentional fires in Malmö, and to analyse how

Alterations in Lung Mast Cell Populations in Patients with COPD.

RATIONALE: Mast cells have important roles in innate immunity and tissue remodeling but have remained poorly studied in inflammatory airway diseases like COPD. OBJECTIVES: To perform a detailed histological characterization of human lung mast cell popu-lations at different severities of COPD, comparing with smoking and never-smoking controls. METHODS: Mast cells were analyzed in lung tissues from
