Impact of Drinking Water Treatment and Pipe Biofilms on Bacterial Dynamics in the Distribution System

This thesis addresses drinking water quality and microbiology in full-scale drinking water distribution systems (DWDSs). It examines how UV irradiation and slow sand filters (SSFs) alter the water bacteriome, and how the biofilm in the DWDS affects the drinking water quality.In addition, the effects of installing a combined ultra­filtration and coagulation treatment stage on the pipe biofilm com­m

Cultural and heritage tourism in the Middle East and North Africa : Complexities, management and practices

This is the first book to provide a comprehensive account of cultural and heritage tourism in the Middle East and North Africa (MENA) region and the many complexities that heritage sites and tourist attractions face. The MENA region has long been regarded as the cradle of Western and Arab civilisation and is the home of many of the world’s major religions. Because of this, the region is rich in he

Conclusion : The futures of cultural heritage tourism in the MENA countries

The chapter outlines the main themes that emerge in discussing the futures of cultural heritage tourism in the MENA region. Six main themes are identified. The tensions between the social and economic dimensions of heritage are illustrated in the construction of heritage, especially for international and domestic tourists. These tensions are also to be found in the wat in which heritage is deliber

Cultural heritage tourism in the MENA : Introduction and background

The Middle East and Sorth Africa (MENA) is a large, complex, and diverse region and is viewed as a huge centre of cultural and travel influence. Nevertheless, the region has been plagued by geopolitical tensions, political turmoil, instability, and conflict over the decades. The conflict-ridden and controversial image of the region in many tourism-generating markets has negatively affected the flo

Toward allele-specific targeting therapy and pharmacodynamic marker for spinocerebellar ataxia type 3

Spinocerebellar ataxia type 3 (SCA3), caused by a CAG repeat expansion in the ataxin-3 gene (ATXN3), is characterized by neuronal polyglutamine (polyQ) ATXN3 protein aggregates. Although there is no cure for SCA3, gene-silencing approaches to reduce toxic polyQ ATXN3 showed promise in preclinical models. However, a major limitation in translating putative treatments for this rare disease to the cl

Implications of land use on the carbon cycle - Impacts of long-term human activities on terrestrial organic matter input to aquatic ecosystems in southern Sweden

Human activities have a huge impact on the carbon cycle by modifying the landscape. Vegetation cover changes attributed to forest clearance and the expansion of agricultural land increases soil erosion, organic matter and other nutrient delivery from terrestrial to aquatic ecosystems. Long-term records of environmental variation at centennial to millennial time scales are essential for the assessm

RIFM fragrance ingredient safety assessment, 2-decanone, CAS Registry Number 693-54-9

The existing information supports the use of this material as described in this safety assessment. 2-Decanone was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog 2-heptanone (CAS # 110-43-0) show that 2-decanone is not expected to be ge

20 Years of Nordic climate change crisis and tourism research : a review and future research agenda

Climate change poses an existential crisis for tourism and destinations. Nordic researchers have been at the forefront of research on climate change impacts, adaptation and mitigation. The review provides a brief account of some of the main themes in Nordic climate change research from a regional and international perspective and potential future research directions. Key themes identified include

Imaging properties of beam line optics for undulator based third generation synchrotron facilities

Beam line optics for synchrotron facilities are generally designed from geometric calculations wherein the bending magnet, undulator, or wiggler photon source is approximated by a high divergence point source. In this article we will, however, show that in the case of a synchrotron radiation source with very small divergence (such a source can be encountered at an undulator based third generation

Breast cancer survival in Nordic BRCA2 mutation carriers—unconventional association with oestrogen receptor status

Background: The natural history of breast cancer among BRCA2 carriers has not been clearly established. In a previous study from Iceland, positive ER status was a negative prognostic factor. We sought to identify factors that predicted survival after invasive breast cancer in an expanded cohort of BRCA2 carriers. Methods: We studied 608 women with invasive breast cancer and a pathogenic BRCA2 muta

Current taxonomy of the lichen family Teloschistaceae from India with descriptions of new species

The present study recorded 36 genera and 115 species of the lichen family Teloschistaceae in India. Three species, i.e. Caloplaca rajasthanica S. Y. Kondr., Upreti et G. P. Sinha, Huriella upretiana S. Y. Kondr., G. K. Mishra, Nayaka et A. Thell, and Squamulea uttarkashiana S. Y. Kondr., Upreti, Nayaka et A. Thell, are described as new species. Seven new combinations, i.e. Fulgogasparrea awasthii

Reliably predicting pollinator abundance : Challenges of calibrating process-based ecological models

Pollination is a key ecosystem service for global agriculture but evidence of pollinator population declines is growing. Reliable spatial modelling of pollinator abundance is essential if we are to identify areas at risk of pollination service deficit and effectively target resources to support pollinator populations. Many models exist which predict pollinator abundance but few have been calibrate
