This thesis is focused on the detail process of formation of mesoporous silica materials.Mesoporous silica materials are one type of porous materials with a pore size between 2 and 5 nm (1 nm=0.000 000 001 m). The pore walls consist of silicon dioxide – silica (sand also consists of silica). The mesoporous silica materials are formed by amphiphilic molecules, a kind of molecule with one part that We investigate the formation mechanism responsible for two specific systems of mesoporous silicas formed with the so-called co-structure directing agent (CSDA) route. The synthesis relies on the interactions between silica source (tetraethylorthosilicate, TEOS), surfactants and CSDA. The structures of the mesoporous silica materials were investigated mainly by small angle X-ray diffraction (SAXD),

This paper uses a method devised by Geary and Stark to estimate regional GDPs for 24 Swedish provinces 1855-2007. In empirical tests, we find that the Swedish estimations yield results of good precision, comparable to those reported in the international literature. From the literature, we generate six expectations concerning the development of regional GDPs in Sweden. Using the GDP estimations, we

Training and exercises programmes are not independent activities, forming part of a larger, risk-based, process of disaster management preparedness. In order to have an impact on an individual's skills knowledge or behaviours, or to influence organizational learning or procedures, the programmes needs a cyclic and holistic approach. It should focus on clearly identified outcomes that are designed

This research note presents the major findings of the evaluation of a major power outage in the Netherlands in December 2007 concerning citizen preparation and response. Particular attention is paid to people's perception of the event and its handling.

1. Opioid- and FMRFamide (FMRFa)-ergic systems are believed to play antagonistic behavioral roles in both higher and lower animals. In our previous experiments on a snail, behavioral choice has been demonstrated to be dependent on a balance between FMRFa and enkephalins [7]. Here, we examined if the disturbance of the balance causes changes in the activity of both systems. Opiate receptor blocker

Hutchinsoniella macracantha is a simultaneous hermaphrodite. The small, paired ovaries are cephalic. From each, a long oviduct runs posteriorly to the eighteenth trunk segment, where it loops forward and runs toward the sixth trunk segment. The paired, sausage-shaped testes are dorsal to the midgut in the anterior end of the abdomen. A vas deferens runs down from the anterior end of each testis to

A new Swedish construction classification system, CoClass, is now under development. CoClass has presented two alternative classifications for review, both based on the standard for construction classification ISO 12006-2:2015. One alternative also applies the IEC CD 81346-series for reference designations which includes classification tables for systems and components with function as the basis f

This thesis contributes to the empirical energy finance literature and consists of three research papers. The common denominator for all papers is the multivariate modelling approach, placing the electricity market at the core and delving into its interdependencies on fundamentally related markets and factors.In the first paper, we focus on the multivariate modelling of the return series of electr

This paper contains some new results on the hadronic light-by-light contribution (HLbL) to the muon g − 2. The first part argues that we can expect large effects from disconnected diagrams in present and future calculations by lattice QCD of HLbL. The argument is based on the dominance of pseudo-scalar meson exchange. In the second part, we revisit the pion loop HLbL contribution to the muon anoma

In 2007, Chinese Ministry of Education (MOE) and Ministry of Housing & Urban-Rural Development (MOHURD) carried out the Campus Resource Conservation Actions, in order to take full use of resources and to improve the energy efficiency. However, due to the large amounts of universities, the total energy consumption and the energy efficiency situation have no objective statistics. Taking modeling

A novel pilot-control globe valve, which can be used in vertical pipelines with a lower driving energy consumption, is proposed. A governing equation for valve core motion is obtained through a theoretical analysis of the forces applied on the valve core. A 3D simulation of valve core motion is conducted in Fluent by using User Defined Function (UDF) to involve different spring stiffness, steady s

The pilot-control globe valve (PCGV) is a novel globe valve with a piston-type valve core and a small pilot valve. It can utilize a pressure difference to control the state of the main valve by the pilot valve. In this paper, a mathematical model of PCGV is established and a computational fluid dynamics (CFD) method is used to numerically simulate its flow and cavitation characteristics. Analysis

This paper introduces the concept of 'dynamic capability' (DC) in relation to disaster management - in particular to disaster management exercises (DME). Firstly this paper discusses changes and challenges in DME and the concept of dynamic capabilities as one potential approach dealing with the existing challenges in DME. Thereafter it outlines basic contents of developing DC in DME. The paper con

Preparedness is the key to provide an effective response to drowning, whether it is a single person at risk of drowning through unplanned entry into water or a larger number through a disaster such as flooding. Preparedness is achieved by training and exercise. There is increased awareness that water search and rescue response needs to become more effective as worldwide flood risks grow [1]. Teams

The main objective of this paper is to study the characteristics of flow-induced noise in high pressure reducing valve (HPRV) and to provide some guidance for noise control. Based on computational fluid dynamics (CFD), numerical method was used to compute flow field. Ffowcs Williams and Hawkings Model was applied to obtain acoustic signals. The unsteady flow field shows that noise sources are loca

In this article I present findings from my earlier research on reconciliation in South Africa and Northern Ireland, together with some issues raised by my current research project on “reconciliation in South Africa from women’s perspectives”. Reconciliation is seen as a process whereby the diverse “moral landscapes” held in a war-torn society are addressed, with the aim of building, rebuilding or
