Nonequilibrium Particle Morphology Development in Seeded Emulsion Polymerization. II. Influence of Seed Polymer Tg.

Most structured latex particles are formed in the nonequilibrium state as a result of the reaction kinetics proceeding faster than the phase separation kinetics. Of the many factors controlling such morphologies, the polarity and glass transition temperature (Tg) of the seed polymer are important. In order to study the direct effect of the seed polymer Tg on morphology, we produced a series of pol

Gastric inflammatory markers and interleukins in patients with functional dyspepsia, with and without Helicobacter pylori infection

Helicobacter pylori is the most important cause of gastritis, peptic ulcers and the development of gastric cancer. The chronic active inflammation is dominated by neutrophils, macrophages, lymphocytes and plasma cells. Several interleukins (IL-8, IL-10 and IFN-gamma) are involved in the inflammatory process in the gastric mucosa. The aim of this study was to investigate the gastric inflammation in

Jurassic volcanism in Skane, southern Sweden, and its relation to coeval regional and global events

Isolated exposures of basalt in a 1000 km 2 area in the central northern part of Skane have long been known to the local people. A volcanic origin for these rocks was finally resolved by geologists during the early 1800s. Until 1965 the volcanic activity was considered to have occurred during the Cenozoic i.e. not older than 65 Ma. In the 1970s attempts were made to directly date the volcanic acti

Admission control for multicast routing with quality of service in ad hoc networks

Ad hoc networks, being able to organize themselves without user intervention, can easily provide their users with mobility, multimedia support and group communication. However, they have to combine quality of service (QoS) and multicast routing strategies. This article defines the resource management and admission control components of the ad hoc QoS multicast (AQM) routing protocol, which achieve

Bioelectrocatalytic properties of lignin peroxidase from Phanerochaete chrysosporium in reactions with phenols, catechols and lignin-model compounds

Bioelectrocatalytic reduction of H2O2 catalysed by lignin peroxidase from Phanerochaete chrysosporium (LiP) was studied with LiP-modified graphite electrodes to elucidate the ability of UP to electro-enzymatically oxidise phenols, catechols, as well as veratryl alcohol (VA) and some other high-redox-potential lignin model compounds (LMC). Flow-through amperometric experiments performed at +0.1 V v

Stored blood transfusion induces transient pulmonary arterial hypertension without impairing coagulation in an ovine model of nontraumatic haemorrhage.

BACKGROUND AND OBJECTIVES: Transfusion of blood products in particular older products is associated with patient morbidity. Previously, we demonstrated a higher incidence of acute lung injury in lipopolysaccharide-treated sheep transfused with stored blood products. As transfusion following haemorrhage is more common, we aimed to determine whether a 'first hit' of isolated haemorrhage would prec

A systematic approach for identifying lean and green improvements related to packaging material in assembly

One significant environmental impact from assembly operations includes packaging material use and subsequent waste generation. Although current practice involves reduction of unnecessary materials handling, there is potential to adapt packaging material in order to simultaneously improve the environmental performance and reduce cost in a “lean and green” mindset. Hence, with increased emphasis on

International expansion through flexible replication: Learning from the internationalization experience of IKEA

Business organizations may expand internationally by replicating a part of their value chain, such as a sales and marketing format, in other countries. However, little is known regarding how such "international replicators" build a format for replication, or how they can adjust it in order to adapt to local environments and under the impact of new learning. To illuminate these issues, we draw on a

Interactions between Predation and Resources Shape Zooplankton Population Dynamics.

Identifying the relative importance of predation and resources in population dynamics has a long tradition in ecology, while interactions between them have been studied less intensively. In order to disentangle the effects of predation by juvenile fish, algal resource availability and their interactive effects on zooplankton population dynamics, we conducted an enclosure experiment where zooplankt

What makes a best exemplar?

This paper is part of a broader multilingual research project that addresses the relationships between affective phenomena (as units of personal experience), concepts (as units of cognitive processing) and the lexical items we use in talking about affective experience (as units of verbal communication. The focus will be here on data obtained in six Scandinavian and Romance languages (N=1093) with

Design/methodology/approach – The paper incorporates a mix of quantitative analysis, based primarily on original analysis of national farm household survey data, toge

Tourists and Global Environmental Change: A Possible Scenario in Relation to Nature and Authenticity

The aim of this chapter is to discuss global environmental change (GEC) through the social construction of nature and notions of authenticity. We will discuss the social construction of nature in a specific context, namely that of different kinds of nature-based tourism. The argument will revolve around what we perceive as a shift in focus from the image of nature as thing to nature as experience,

Women’s Agency in Transforming Religious Discourse: Gender-Sensitive Interpretations of Islam in Indonesia

The purpose of this article is to present and analyse gender sensitive interpretations of Islam in Indonesia and a reform of fiqh from a gender perspective. These interpretations can be seen as an expression of Islamic feminism, a discursive framework that has grown from the Islamisation processes of Muslim societies in the 1980s. Another aim is to depict the specific Indonesian environment where

Gas Flow and Heat Transfer Analysis for an Anode Duct in Reduced Temperature SOFCs

In this study, a fully three-dimensional calculation method has been further developed to simulate and analyze various processes in a thick anode duct. The composite duct consists of a porous layer, the flow duct and solid current connector. The analysis takes the electrochemical reactions into account. Momentum and heat transport together with gas species equations have been solved by coupled sou

On Self-Tuning Regulators

The problem of controlling a system with constant but unknown parameters is considered. The analysis is restricted to discrete time single-input single-output systems. An algorithm obtained by combining a least squares estimator with a minimum variance regulator computed from the estimated model is analyzed. The main results are two theorems which characterize the closed loop system obtained under

Quantifying differences between computational results and measurements in the case of a large-scale well-confined fire scenario

The objective of this work was to quantify comparisons between several computational results and measurements performed during a pool fire scenario in a well-confined compartment. This collaborative work was initiated under the framework of the OECD fire research program and involves the most frequently used fire models in the fire community, including field and zone models. The experimental scena

Rheological Investigations on the Creaming of Depletion-Flocculated Emulsions

Preventing creaming or sedimentation by the addition of thickeners is an important industrial challenge. We study the effect of the addition of a "free" nonadsorbing polymer (xanthan gum) on the stability against creaming of sterically stabilized O/W emulsions. Therefore, we analyze our samples using microscopy and rheological measurements. At low xanthan concentrations, the emulsions cream. Howev

Long-term temporal and spatial trends in eutrophication status of the Baltic Sea

Much of the Baltic Sea is currently classified as 'affected by eutrophication'. The causes for this are twofold. First, current levels of nutrient inputs (nitrogen and phosphorus) from human activities exceed the natural processing capacity with an accumulation of nutrients in the Baltic Sea over the last 50-100 years. Secondly, the Baltic Sea is naturally susceptible to nutrient enrichment due to
