Popular Abstract in English This study concerns the city of Damascus in the Syrian Arab Republic. Damascus is a city where the current urban form is characterized by wide streets and lack of shade as well as limited amount of green areas, which negatively affect the microclimate and thermal comfort. This study is mainly focused on residential streets and how the urban planning regulations affect tThis research is an attempt to develop further understanding of the relationship between microclimate, thermal comfort, urban design and outdoor space users in the hot dry city of Damascus. This is done by studying the impact of urban regulations on microclimate in different urban design patterns in Damascus. This study also aims to investigate the behaviour of different thermal comfort indices an

Popular Abstract in Swedish Hårdare krav på lägre energianvändning i byggnader samt ökade energipriser har gjort att välisolerade hus har blivit vanligare. Ökad medvetenhet om koldioxidens påverkan på klimat-förändringarna har också ökat intresset för trähus. Tjockare isolering ökar dock risken för höga fukttillstånd och med detta också risken för fuktskador. För att förutse och undvika fuktskadorDue to increased awareness of climate change and higher energy costs, well-insulated buildings have become more common. Furthermore, interest in the use of wood in building to produce more carbon dioxide-efficient buildings has increased. However, thicker thermal insulation in building envelopes increases the risk of high relative humidity levels and the risk of mold-related damage in wood frame b

The Swedish Antarctic Research Expedition named “SWEDARP” was performed during October 1988 through April 1989. The aim of our project was to study the radioactivity in air and water from Gothenburg to the Antarctic. Between Gothenburg and the Equator, the average activity concentration of 7Be in air was 4.3 ± 0.7 mBq/m3. The activity concentration of 7Be in the South Atlantic down to Antarctica v

The Swedish National Road Administration SNRA is responsible for the long term de-velopment of the road transport system, and spends large sums on road construction and 'operation and maintenance'. Improvements in efficiency which are small in per-centage terms therefore yield relatively large monetary effects. In order to create and maintain a strong and competitive road construction sector and a

Recent decades have been characterised by increasingly complex governance structures. In order to tackle threats from epidemics, environmental degradation and other trans-boundary problems governments collaborate not only with actors from other governments, international agencies and civil society, but also from the private sector and business community. Large numbers of global partnerships, inclu

Humidified gas turbines (HGT) offer the attractive possibility of increasing plant efficiency without the cost of an additional steam turbine as is the case for a combined gas-steam cycle. In addition to efficiency gains, adding steam into the combustion process reduces NOx emissions. It increases the specific heat capacity (hence, lowering possible temperature peaks) and reduces the oxygen concen

Kisel är ett vanligt förekommande grundämne som gärna bildar en oxid, nämligen kiseldioxid. Kiseldioxid träffar man i hög utsträckning på i det dagliga livet. Det är nämligen huvudbeståndsdelen i sand, glasvaror, kvarts, många keramiska material men också i den färgskiftande ädelstenen opal. Det finns också flera grupper av porösa kiseldioxidmaterial, till exempel så kallade zeoliter som har myckeThe formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. For zeolites the SDAs are molecular and for mesoporous silica the SDAs assem

At the very core of this thesis is the motivation to better understand how the seemingly inherent connection between powerful social agents and judges is produced and reproduced. The thesis also seeks to contribute to the view that who judges matters. This is not only true for the identity of the institutions they comprise, but for the individuals they adjudicate on behalf of. As a result, there e

Producing electrical power with photovoltaic solar panels is very attractive as the sun constitutes an inexhaustible source of clean energy. However, in order to make it a better alternative to other energy sources, its drawbacks must be addressed. In particular, scientific research is very active to find technologies that increase the efficiency of the solar cells, or decrease their cost. Reducin

“The management of innovation is inherently difficult and risky, most new technologies fail to be translated into products and services, and most new products and services are not commercial successes. In short, innovation can enhance competitiveness, but it requires a different set of management knowledge and skills from those of everyday business administration” (Bessant et al. 2005 p. 1). The a

Knowledge acquired through ecosystem service valuations can provide valuable information to stakeholders making land-use decisions. Effective use of ecosystem service valuation knowledge with a cost-benefit analysis can create resilient social-ecological systems. There is an increasing number of valuations being conducted, yet only one third of the studies are thought to be used in some form to ai

An experimental study of the Homogeneous Charge Compression Ignition (HCCI) combustion process has been conducted by using chemiluminescence imaging. The major intent was to characterize the flame structure and its transient behavior. To achieve this, time resolved images of the naturally emitted light were taken. Emitted light was studied by recording its spectral content and applying different f

Over the years several models have been developed to describe hydrophobic pervaporation. The different approaches can be generally classified as process-orientated or membrane-orientated. Among these models the resistance-in-series model (RSM) has a unique position since it combines process conditions with membrane parameters. The aim of this work is to demonstrate the extension of the RSM to c

This chapter provides an introduction to task engagement as a framework for better understanding how individuals participate in and learn from second language activities in their leisure time. Although the concept is relatively new to second language acquisition research, engagement has been extensively studied in educational science, as a way of operationalising different aspects of students’ par

Experimental work in turbid media has shown that transillumination images can be significantly improved by limiting light collection to a subset of photons which are minimally distorted by scattering. The literature details numerous schemes (commonly termed ballistic imaging), most often based on time-gating and/or spatially filtering the detected light. However, due to the complex nature of the d

Symposium 22 August: Prediction in Speech Processing Symposium 22 August: Prediction in Speech Processing Published 15 August 2025 This symposium brings together leading researchers to examine how the brain anticipates forthcoming speech—from prosodic cues and lexical forms to semantic content. Topics include neural markers of prediction in the sub-lexical level, anticipatory brain activity in sen

This thesis investigates the performance and feasibility of passive and active analog frequency compensation filters for audio signal processing in a distributed speaker system. One passive and one active circuit topology were investigated more thoroughly and then the active filter was realized on a PCB and evaluated with electrical, thermal and acoustic measurements. The work also resulted in tw

This research has explored the role actors from various scales have in the production of Research, Innovation and Smart Specialisation Strategies (RIS3) in the Eastern and Southern Netherlands through its multi-level governance framework. This could be worrying, as the influence from higher-scale actors could weaken RIS3’s ability to create place-based programmes. In order to gain an understanding
