Ecosystem services - current challenges and opportunities for ecological research

e concept of ecosystem services was originally developed to illustrate the benefits that natural ecosystems generate for society and to raise awareness for biodiversity and ecosystem conservation. In this article we identify major challenges and opportunities for ecologists involved in empirical or modeling ecosystem service research. The first challenge arises from the fact that the ecosystem ser

Is it a policy crisis or it is a health crisis? The Egyptian context--analysis of the Egyptian health policy for the H1N1 flu pandemic control.

A new influenza virus that was first detected in people in April 2009, was initially referred to colloquially as "swine flu", since it contained genes from swine, avian and human influenza viruses. It can, however, not be transmitted by eating pork or dealing with pigs. In Egypt, several hundred thousand pigs were killed in May, in spite of advice from global health authorities that such an action

A comparative reactivity study of microperoxidases based on hemin, mesohemin and deuterohemin

Three microperoxidases-hemin-6(7)-gly-gly-his methyl ester (HGGH), mesohemin-6(7)-gly-gly-his methyl ester (MGGH) and deuterohemin-6(7)-gly-gly-his methyl ester (DGGH)-have been prepared as models for heme-containing peroxidases by condensation Of glycyl-glycyl-L-histidine methyl ester with the propionic side chains of hemin, mesohemin and deuterohemin, respectively. The three microperoxidases dif

Multi-Output Control of a Heavy Duty HCCI Engine Using Variable Valve Actuation and Model Predictive Control

Autoignition of a homogeneous mixture is very sensitive to operating conditions, therefore fast control is necessary for reliable operation. There exists several means to control the combustion phasing of an Homogeneous Charge Compression Ignition (HCCI) engine, but most of the presented controlled HCCI result has been performed with single-input single-output controllers. In order to fully operat

Cities and Regions in the New Learning Economy

The process of transforming the industrial economy into a society largely based on the production and dissemination of information and knowledge has widespread implications for cities and regions as well as organisations and individuals. And while the economy is increasingly global, the differences in economic development between cities and regions will not necessarily disappear. Indeed, the diver

Alkali Metal Adsorption on Metals Studied by Hiqh Resolution Core Level Spectroscopy and Low Energy Electron Diffraction

Alkali metal adsorption on metals is studied by High Resolution Core Level Spectroscopy (HRCLS) and Low Energy Electron Diffraction (LEED). The studies can be divided into two parts: adsorption of alkali multilayers and alkali adsorption in the submonolayer regime. In the case of the adsorption of alkali multilayers, the interface region between a thin alkali film of Na,K,Rb and Cs on different s

Fields of Green and Gold : Territorial hunger, rural planning, and the political ecologies of high-end golf

Fields of Green and Gold är en multipel fallstudie som analyserar placeringen och etableringen av två storskaliga, berömda och påkostade golfanläggningar för att därigenom undersöka den exklusiva golfens politiska ekologi. De fall som studeras är Bro Hof Slott Golf Club i Upplands-Bro - som öppnade 2007 - och Trump International Golf Links Scotland i Aberdeenshire - som öppnade 2012. Att analyseraFields of Green and Gold is a multiple case study analysing the placing and establishment of two large-scale, high-profile, upmarket golf developments with the aim of exploring a political ecology of high-end golf. The cases studied are Bro Hof Slott Golf Club in Upplands-Bro, opened in 2007, and Trump International Golf Links Scotland in Aberdeenshire, opened in 2012. Reading these two cases toge

Are we there yet? A legal assessment and review of the concept of sustainable development under international law

Some of the most consistently utilized terms in international environmental law are “sustainable development” and “sustainability”. Sustainable development is mentioned in virtually every domestic, regional and international laws on environment, energy and natural resources. This has led to the contentions by some scholars that the concept of sustainable development has matured into customary inte

Scale-dependent natural variation in larval nutritional reserves in a marine invertebrate : Implications for recruitment and cross-ecosystem coupling

In species with complex life cycles, laboratory studies have shown that variations in the traits of settling larvae can affect post-settlement survival and influence recruitment and benthic- pelagic coupling. However, we still know little about the magnitude and spatial scale of natural trait variation. We studied spatial variation in body size and nutritional reserves (carbon, nitrogen and lipids

Expression of flTF and asTF splice variants in various cell strains and tissues

Tissue factor (TF) expressed at the protein level includes two isoforms: The membrane‑bound full‑length TF (flTF) and the soluble alternatively spliced TF (asTF). flTF is the major thrombogenic form of TF, whereas asTF is more closely associated with tumor growth, angiogenesis, metastasis and cell growth. In order to further investigate the different expression and functions of TF splice variants,

Translations of health sector SWAps-A comparative study of health sector development cooperation in Uganda, Zambia and Bangladesh

Introduction: Sector-wide approach, or SWAp, is an increasingly popular approach to development cooperation for many bilateral and multilateral development agencies. While much has been published about the SWAp model itself, there is still limited research conducted on how it is applied in practice. This study aims at showing how the SWAp is translated as it is adopted in different local settings

Multi-centre evaluation of accuracy and reproducibility of planar and SPECT image quantification : An IAEA phantom study

Accurate quantitation of activity provides the basis for internal dosimetry of targeted radionuclide therapies. This study investigated quantitative imaging capabilities at sites with a variety of experience and equipment and assessed levels of errors in activity quantitation in Single-Photon Emission Computed Tomography (SPECT) and planar imaging. Participants from 9 countries took part in a comp

Gaia Data Release 1 : On-orbit performance of the Gaia CCDs at L2

The European Space Agency's Gaia satellite was launched into orbit around L2 in December 2013 with a payload containing 106 large-format scientific CCDs. The primary goal of the mission is to repeatedly obtain high-precision astrometric and photometric measurements of one thousand million stars over the course of five years. The scientific value of the down-linked data, and the operation of the on

A developmental etiological model for drug abuse in men

Background We attempt to develop a relatively comprehensive structural model of risk factors for drug abuse (DA) in Swedish men that illustrates developmental and mediational processes. Methods We examined 20 risk factors for DA in 48,369 men undergoing conscription examinations in 1969–70 followed until 2011 when 2.34% (n = 1134) of them had DA ascertained in medical, criminal and pharmacy regist

Decreasing organic carbon bioreactivity in European rivers

European rivers experience increased loading of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, little is known about how increased TOC is linked to changes in the bioreactivity of organic matter in these rivers on a continental scale. We compiled paired measurements of TOC and biological oxygen demand in 5‐day 20

User Knowledge Management – How University Libraries Analyse User Needs and Develop Services

The demands on library services are quickly changing in a continually updating digital age. This increases the importance of a good understanding of the needs and demands of the users. In order to sample and follow the change in user needs library organisations analyse their efforts using a series of different methods. In a recent survey distributed to all 301 European LIBER university libraries,

Dynamic urban land-use change management using multi-objective evolutionary algorithms

Frequent land-use changes in urban areas require an efficient and dynamic approach to reform and update detailed plans by re-arrangement of surrounding land-uses in case of change in one or several urban land-uses. However, re-arrangement of land-uses is problematic, since a variety of conflicting criteria must be considered and satisfied. This paper proposes and examines a two-step approach to re

A Comparative Study of Four Metaheuristic Algorithms, AMOSA, MOABC, MSPSO, and NSGA-II for Evacuation Planning

Evacuation planning is an important activity in disaster management to reduce the effects of disasters on urban communities. It is regarded as a multi-objective optimization problem that involves conflicting spatial objectives and constraints in a decision-making process. Such problems are difficult to solve by traditional methods. However, metaheuristics methods have been shown to be proper solut
