Modelling anaerobic co-digestion in Benchmark Simulation Model No. 2 : Parameter estimation, substrate characterisation and plant-wide integration

Anaerobic co-digestion is an emerging practice at wastewater treatment plants (WWTPs) to improve the energy balance and integrate waste management. Modelling of co-digestion in a plant-wide WWTP model is a powerful tool to assess the impact of co-substrate selection and dose strategy on digester performance and plant-wide effects. A feasible procedure to characterise and fractionate co-substrates

Mini Projects Solution for Energy, Wastewater and Water for the Gaza Strip, Palestine

Gaza has several water problems; limited fresh water supply, inefficient water use by the agricultural sector, high water demand, groundwater contamination, seawater intrusion and shortage of electricity. Water and electricity is the first priority for Gaza that will add significant positive values to the Palestinians living in blocked Gaza and easy operation and maintenance of their ongoing and e

Politikens drivfjäder : Frihetstidens partiberättelser och den moralpolitiska logiken

Denna avhandling studerar den moraliska konfliktlinje som genomsyrade den frihetstida politiken åren kring 1740 och som strukturerade politiken enligt en särskilt moralpolitisk logik. Logiken hade sin grund i dels samhällsordningens absoluta och normativt oföränderliga karaktär, dels ett antal djupa förmoderna erfarenheter av och förväntningar på människan som oförmögen att hantera sin fördärvade This thesis examines the moral conflict permeating the politics of Sweden’s Age of Liberty around 1740 – a conflict that also structured the politics of the time in relation to a particular political logic based on moral. This logic was based on the absolute and normatively immutable nature of the social order, but also on a number of deep pre-modern experiences and expectations of man as unable t

Exploring the functional heterogeneity of the tumor microenvironment

Tumors are complex entities, composed of different functional populations of malignant and stromal cells. There is an emerging importance to understand previously unmapped communication routes between different cell and non-cell compartments of the tumor microenvironment. Targeted drugs have been used for years in an attempt to block essential pathways for tumor growth. Specifically, drugs targeti

Industry attitudes towards ecodesign standards for improved resource efficiency

Current European regulations on producer responsibility provide limited incentives for ecodesign practices among manufacturers. Additional incentives for 'design for resource efficiency' and 'design for recycling' could be provided through mandatory design standards set under the Ecodesign Directive. While European manufacturers have become increasingly positive towards eco-design standards for en

Waste management: The Other of production, distribution, and consumption

Italian novelist Italo Calvino ([1972] 1974: 102–103) described Leonia as a city where ‘every morning the people wake between fresh sheets, wash with just-unwrapped cakes of soap, wear brand-new clothing, take from the latest model refrigerator still unopened tins, listening to the last-minute jingles from the most up-to-date radio’. This opulent newness is dependent upon garbage trucks collecting

Advancing sustainable solutions : An interdisciplinary and collaborative research agenda

Sustainable solutions are needed to drive a profound industrial and societal transformation towards a sustainable, low-carbon, resilient, equitable and prosperous future. This Special Volume of the Journal of Cleaner Production addresses possibilities and drivers for change by focusing on strategies for sustainable solutions with the underlying purpose of defining an interdisciplinary and collabor

PEAS: A Performance Evaluation Framework for Auto-Scaling Strategies in Cloud Applications

Numerous auto-scaling strategies have been proposed in the past few years for improving various Quality of Service (QoS) indicators of cloud applications, for example, response time and throughput, by adapting the amount of resources assigned to the application to meet the workload demand. However, the evaluation of a proposed auto-scaler is usually achieved through experiments under specific cond

Framework for a virtual nursing faculty and student learning collaboration between universities in Sweden and the United States : A theoretical paper

A sound pedagogical framework must be explored and identified to implement opportunities for collaborative learning through international exchange. This paper identifies the framework used by two universities, in Sweden and the United States. Virtual learning environments and meaningful learning activities can be constructed using web-based learning platforms. The goal for this initiative was 'int

Glucose-dependent insulinotropic polypeptide (GIP) and GIP receptor (GIPR) genes : An association analysis of polymorphisms and bone in young and elderly women

Introduction: The gastro-intestinal hormone glucose-dependent insulinotropic polypeptide (GIP) potentiates glucose-induced insulin secretion, with bone anabolic effects through GIP receptor (GIPR) in animal models. We explore its potential in humans by analyzing association between polymorphisms (SNPs) in the GIP and GIPR genes with bone phenotypes in young and elderly women. Methods: Association

National environmental objectives in Sweden : A critical reflection

The National Environmental Objectives (NEOs) adopted by Swedish Parliament in 2001 and proclaimining that major environmental problems should be solved within a generation are often portrayed as good practice of a concrete yet visionary sustainability strategy. In this paper we summarize one and a half decade of the NEOs' experience for the international audience. The NEOs were based on an eclecti

Mitotic History Reveals Distinct Stem Cell Populations and Their Contributions to Hematopoiesis

Homeostasis of short-lived blood cells is dependent on rapid proliferation of immature precursors. Using a conditional histone 2B-mCherry-labeling mouse model, we characterize hematopoietic stem cell (HSC) and progenitor proliferation dynamics in steady state and following several types of induced stress. HSC proliferation following HSC transplantation into lethally irradiated mice is fundamentall

Evidence for neural contribution to islet effects of DPP-4 inhibition in mice

It has been suggested that neural mechanisms may contribute to effects of the incretin hormones, and, therefore, also to the effects of dipeptidyl peptidase (DPP-4) inhibition. We therefore examined whether muscarinic mechanisms are involved in the stimulation of insulin secretion by DPP-4 inhibition. Fasted, anesthetized mice were given intraperitoneal saline or the muscarinic antagonist atropine

The Politics of Combat : The Political and Strategic Impact of Tactical-Level Subcultures, 1939-1995

This dissertation argues that lower-level military leaders, commanding between a dozen and a few hundred troops, can have a major political and strategic impact. Furthermore, it is argued that the decisions made by these lower-level military leaders are shaped by subcultures, in particular under conditions of stress and uncertainty. The concept of tactical-level subcultures is defined, drawing on

Control-Based Load-Balancing Techniques: Analysis and Performance Evaluation via a Randomized Optimization Approach

Cloud applications are often subject to unexpected events like flashcrowds and hardware failures. Users that expect a predictable behavior may abandon an unresponsive application when these events occur. Researchers and engineers addressed this problem on two separate fronts: first, they introduced replicas - copies of the application with the same functionality - for redundancy and scalability; s

In defence of the fundamental values of society: an analysis of blasphemy trials and debates in Sweden around 1900

Critique of religion and its consequences is a topical theme. The attack on the satirical magazine Charlie Hebdo in Paris in January 2015 made the Western media establishment to rally in defence of freedom of expression, but it also raised the question of the limits of this freedom. There are always defined limits to freedom of expression, which change over time and are adapted to the political sy

A nickel (II) PY5 complex as an electrocatalyst for water oxidation

A Ni-PY5 [PY5 = 2,6-bis(1,1-bis(2-pyridyl)ethyl)pyridine)] complex has been found to act as an electrocatalyst for oxidizing water to dioxygen in aqueous phosphate buffer solutions. The rate of water oxidation catalyzed by the Ni-PY5 is remarkably enhanced by the proton acceptor base HPO42−, with rate constant of 1820 M−1 s−1. Controlled potential bulk electrolysis with Ni-PY5 at pH 10.8 under an

Interaction of Hydrogen and Oxygen with Nanocrystalline Diamond Surfaces

Nanocrystalline diamond films (NCD) are strong candidates for applications in a wide variety of fields. An important concern in all these applications is to understand the properties of variously prepared NCD surfaces. This contribution is focussed on the surface science study of hydrogen and oxygen containing NCD films using X-ray photoelectron spectroscopy (XPS) as well as high resolution electr
